Exactly How The Paper Pulp Molding Machine Works

Descripción: The paper pulp molding machine is responsible for creating molded pulp, which has become an ideal material when it comes to packaging. In the past years, the molded-pulp was typically used simply to produce cartons and egg trays. However, the adaptability and sustainability of such processes has resulted in many different industries choosing these methods over packaging materials that are environmentally-harmful for example plastic. The paper pulp molding machine has additionally grown in popularity mainly because these particular materials are recyclable. We are the best one of pulp molding machine suppliers. Introduction To The Pulp Molding Machines The makers of molded-pulp typically take into account the fibers (materials) how the want to use in the pulp-molding machines. Materials like paper are simple to transform in to a pulp in addition to being easy enough when it comes to shaping. The manner in which these pulp-molding machines jobs are to first mix the materials with water. The presser on these pulp molding machines typically features built in blenders that perform task of turning this mixture into pulp. This mixture will then be typically transferred in a paper “egg-tray” making machine that includes a built-in mold. This is the process that the material is exposed to a set temperature. Following the mold has become heated it would move through the dryer as well as the vacuum. This just about sums up basic functionalities of the pulp molding machine. The working principle is similar to the egg tray machine. The advanced designs of today are able to improve end-products further when it comes to making the item denser and providing it with specific shapes which is suitable when it comes to many different purposes. As an example, once a basic form of pulp-molded package is generated it will typically undergo subsequent processes referred to as “after pressing.” This procedure involves providing these packages using their final and further improved shape. These capabilities are what highlight the flexibility from the pulp-molding technology. In addition, it really is worthwhile to keep in mind that the paper pulp molding machine can be utilized for a variety of other purposes over and above packaging. For example, these machines are able to produce items such as bowls, plates and utensils, together with cushioning and protection for other packaged items. Today a variety of other containers are invented and looked at due to the versatility of molded pulp when it comes to its many applications. The Benefits Of Making Use Of The Paper Pulp Molding Machine While it can be an evident fact that the molded pulp is actually one of the more favorable environmentally-friendly materials currently available, using these materials in addition to a reliance on pulp-molding machines is additionally fantastic for your packaging industries because of the fact that materials including paper that are used with regards to pulp molding are incredibly affordable. Moreover, the exact operations of these pulp-molding machines have the ability to save manufacturers a great deal of their time and money across the long-run. It is because virtually all these pulp-molding machines which can be sold today have already been created in such as way in which they necessitate minimal maintenance as well as leaning towards more energy savings. In addition, this equipment is already famous for high efficiency and also the decrease of the necessity for manual labor. It is not surprising these appliances are already praised as the way forward for packaging materials across the world. We have good quality of apple tray machine for sale. The greater number of that consumers buy their goods which has been packaged inside the pulp-mold packages, the greater we can save our trees and the less landfills will be created. This packaging also decreases the CO2 amounts which get released in to the atmosphere that significantly reduces “producers” contribution towards climatic change. What is EPE Foam? EPE foam, or Expanded Polyethylene foam, processed by EPE bonding and butting machine, is one of the most widely used plastics in production. What is polyethylene foam? It is a thermoplastic resin, which means that it can be melted by heating and cooled to form different shapes and objects. What Are The Physical and Chemical Properties of EPE? The physical and chemical properties of EPE foam are what give it its desirable characteristics. It is due to these properties that this plastic has avariety of applications in different industries such as EPE foam padding, EPE foam tube, and EPE foam sheet. There is also Ps foam machine to process. Physical Properties of EPE Foam EPE foam is a harmless plastic and has no taste or odour. It is a very popular material for packaging goods as it is light in weight and flexible. It has the ability to absorb shock and provide good cushioning to delicate objects. EPE has a high weight to strength ratio and high thermal resistance. It can be heated and melted multiple times, and reshaped into other new objects due to the high EPE foam temperature range. EPE foam is resistant to water, oils, and many chemicals. It is also a very good insulating material. EPE is available in different densities, according to its application or purpose. Chemical Properties of EPE Foam The chemical makeup of expanded polyethylene is similar to most plastics, and of the form (C?H?)nH?. EPE is usually white in colour unless a dye or other colour pigment is added to it during the melting process. EPE foam is also referred to as bead board in the plastic industry. It is a closed cell foam, which allows it to take up more volume and be light weight.

What Is Red Yeast Rice Extract?

Descripción: Red yeast rice extract (RYRE) is a traditional Chinese medicine that has been purported to lower cholesterol. Several types of the extract are sold as supplements. Red yeast rice may be appealing because it's "natural," but you need to be careful. Experts have not studied it extensively. The ideal dosing and its long-term safety are unclear. It could be dangerous for some people. And because the ingredients of different brands of red yeast rice extract might vary so much, it's hard to make firm statements about its effectiveness or safety. What Is Red Yeast Rice Extract? RYRE is a substance that's extracted from rice that's been fermented with a type of yeast called Monascus purpureus. It's been used in China and other Asian countries for centuries as a traditional medicine. It's also used as a food coloring, additive, and preservative. RYRE naturally contains several ingredients that may help control cholesterol levels. These include a number of monacolins, most importantly monacolin K. It also contains sterols, isoflavones, and monounsaturated fatty acids, or "healthy fats." Is Red Yeast Rice Extract a Drug or a Supplement? Confusingly, the answer is both. One of the most important ingredients in RYRE is monacolin K. It's also known as lovastatin, the active ingredient in the prescription drug Mevacor. So on one hand, the extract is a traditional remedy that helps lower cholesterol. On the other, the pharmaceutical manufacturer of Mevacor argues that it owns the rights to the ingredient lovastatin. This confusion extends to how the supplement is sold in the U.S. Because red yeast rice extract contains a substance classified as a prescription drug, the FDA has requested that several RYRE products be withdrawn from the market because they contained monacolin K. The FDA cited a risk of severe muscle problems that could lead to kidney disease. Despite the FDA's attempts, many people in the U.S. still manage to get similar red yeast rice extracts from other countries or on the Internet. How Well Does Red Yeast Rice Lower Cholesterol? Studies have shown that certain red yeast rice products that contain statin can significantly lower levels of total cholesterol and specifically LDL, or "bad" cholesterol. One showed that taking 2.4 grams per day reduced LDL levels by 22% and total cholesterol by 16% in 12 weeks. Another study showed that taking 1.2 grams per day lowered LDL levels by 26% in just eight weeks. However, the results of these studies depend on the amount of statin that is in the extract, and it can vary widely. The FDA considers extracts that contain statins to be illegal in the U.S., but many are still available. What Is the Correct Dosage of Red Yeast Rice Extract? Keep in mind that the amount of monacolin -- perhaps the most important ingredient -- in a organic red yeast rice extract can vary a lot. There are many different strains of the yeast. Different types of fermentation are used. One study of different brands of red yeast rice supplements showed that the amount of monacolin ranged from 0% to 0.58%. So even though studies have shown that RYRE can lower cholesterol, you can't really know if the supplement brand you're using will have that effect. What Are the Risks of Red Yeast Rice? Studies have shown that side effects are mild, like headaches, heartburn, and upset stomach. Side effects from prescription lovastatin include elevation of liver enzymes and muscle enzymes, muscle problems, and liver problems. But more research needs to be done before we can know about the long-term safety of red yeast rice extract. We do know that some types may be more dangerous than others because of high levels of other substances such as citrinic acid. RYRE also shares some of the same risks as statins, the class of drugs containing lovastatin. Experts say that the risks of lovastatin would logically apply to RYRE -- elevation of liver and muscle enzymes, muscle problems, and liver problems. The extract may not be safe for everyone. You should not take it if you: Have kidney disease Have liver disease Are pregnant Are breastfeeding In addition, anyone taking one of the following medicines should not use red yeast rice: Statins to control cholesterol such as lovastatin (Mevacor), rosuvastatin (Crestor), fluvastatin (Lescol), atorvastatin (Lipitor), pravastatin (Pravachol), and simvastatin (Zocor) Other cholesterol drugs such as gemfibrozil (Lopid) and fenofibrate (TriCor) Drugs to suppress the immune system, like cyclosporine Antifungal drugs such as fluconazole (Diflucan), ketoconazole (Nizoral), and itraconazole (Sporanox., The antibiotics erythromycin and clarithromycin (Biaxin) Serzone, an antidepressant Protease inhibitors, used to treat HIV People who have allergies to fungus or yeast should also be wary of using RYRE. The extract may also interact with other drugs for blood pressure and thyroid problems and interact with other herbs and supplements you may be taking. Whatever the state of your health, always talk to your doctor before you start using red yeast rice or any other supplement. Remember that not all brands are equal, and that RYRE isn't safe for everyone. Though red yeast rice extract looks like a promising treatment, more research needs to be done. For now, you should be cautious.

7 Spare Tractor Parts You Need to Have Handy for Preventative Maintenance

Descripción: Preventative maintenance is an important part of owning a tractor. If you want that machine to run as strong as the day you bought it for as long as possible, you have to be dedicated to maintenance every day and at every service milestone. Things tend to break down just when you need them most. You might be gearing up for planting or getting ready to harvest when you find an issue that requires repair of your tractor. Whether you catch it during routine maintenance or out in the field, you need a fix and you need it fast. Replacement Parts for Routine Tractor Repair There’s a long list of issues that can sideline your tractor. If you’re ready with the right parts, you can make the necessary repairs or replacements to get back to farming with little delay. Stock up on the MTZ tractor parts listed in your operator’s manual so you have backup in case something goes wrong. 1. Filters Tractors do the dirty work. So, naturally, they get dirty. A variety of filters help protect critical components from the dirt, debris, and dust they kick up during a day’s work. You’ll need an extra oil filter, air filter, hydraulic filter, and fuel filter to change out old, dirty ones. John Deere makes it easy, providing all four filters your compact tractor needs in one convenient package. Since you need to check and change your fuel and engine oil more frequently, you may want to have several additional filters on hand. 2. Oil and Fuel Despite the best efforts of the filters, oil still gets dirty and can easily gunk up your tractor or cause it to stall out. Engine oil and hydraulic oil are needed for regular maintenance items, so it’s important to have plenty around. On some sub-compact tractors, the hydraulic filter is low to the ground and subject to damage from rough terrain. If a stick or something else breaks your filter, you can lose hydraulic oil quickly, so it’s important to have extra gallons available if you run a smaller compact tractor. Having a full fuel supply might seem obvious but it’s easy to overlook. If you don’t keep an eye on fuel levels, you can waste a lot of time filling up. You also need to ensure your fuel is clean. John Deere diesel fuel conditioner is a fuel additive that improves fuel quality and maintains peak engine efficiency. 3. Fluids and Coolants Oil and fuel are the most important fluids you need to fill to keep your equipment’s engine running. But there’s a wide variety of other fluids that your tractor needs to run efficiently. Checking the engine coolant, hydraulic fluid, radiator fluid, and transmission fluid — and topping off empty tanks — should be part of your daily preventative maintenance routine. Clean coolant helps avoid internal damage, rust, or clogs in the engine, which helps prevent much bigger engine troubles. Many new tractors, including parts like T25 tractor parts, have combined systems where hydraulic or transmission fluid is shared between the machine and an attachment. To keep both your tractor and your implements running at full power, you need full tanks of clean fluid. 4. Light Bulbs It might seem like a minor inconvenience, but burnt bulbs should always be replaced immediately. While you can ignore a slightly dimmer room in your home for weeks, tractor light bulbs are there for safety — yours and those around you. Take stock of the specific light bulbs you need for your headlamps, taillights, and warning lights. Keep them in your shed, garage, or even in the cab of larger utility tractors, so that you can quickly swap out a burnt bulb and keep the lights on. 5. Replacement Belts Your tractor has several different belts that keep your engine running and other components moving. Over time, alternator belts, fan belts, and air compressor belts can loosen, crack, or split. The belts for your specific tractor model may not always be in inventory at your local dealer or tractor supply store. Plan ahead for replacement belts, especially as your tractor approaches the 200-hour mark, to keep a quick and easy switch from causing prolonged downtime. 6. Zerk Fittings Greasing your tractor should be part of your daily maintenance checklist. You need to regularly grease the joints and Zerk fittings on your equipment. Zerk fittings are all over your machine, and many are exposed to wear and tear. While small, a damaged or missing Zerk fitting can contaminate the grease inside your machine and cause much bigger issues. So keep a lot of spare fittings around so you can easily replace broken ones and keep your tractor in good condition. 7. Fuses Whether you’re tractor’s big or small, all agricultural equipment is becoming more and more powered by electrical components. And every electrical circuit on your machine is protected by a fuse. Electrical issues aren’t always expensive fixes. Sometimes, it’s simply a blown fuse. Your tractor’s fuses are color-coded and have the ampere rating clearly marked to ensure proper replacement.

Power Saws & Their Uses

Descripción: Power saws are extremely useful machine tools, but they are also very confusing. There are so many types of saw in different categories and sub-categories of power saw, that it becomes difficult to remember what each kind of saw does. That is the purpose of this article, to act as a sort of “comprehensive guide” to explain the world of various types of power saws. Generally, there are three varieties of power saws namely power saws with rotating blades, with reciprocating blade and circulating blade, including electric wood cutting saw. If you have ever played the word game CodyCross then you probably have across the puzzle: Power tool with rotating blade. The answer is BUZZSAW. But what is a buzzsaw? It is nothing but a circular saw. Most of the electric saws fall under this classification. In this guide, I’m going to give you a very brief explanation as to what each kind of power saw does, what it is good for, etc. My hope is that this saw guide will be useful for both beginners, who know nothing about power saws and professionals who are familiar with power saws, but who are also looking to expand their knowledge. Table saws are one of the workhorses of any workshop or garage. Everyone from professionals to home DIYers use this tool often. In my experience, it is hard to think of a woodworking or carpentry job that does not require you to use a table saw at least once. Table saws are very simple, a circular saw blade is spun at high speeds at a stationary position and the operator pushes the wood into the blade. There is some room for customization, especially with regards to the blade, which can be changed to accommodate different kinds of jobs. However, ultimately the table saw is a simple, but effective tool. Working Principle: The circular table saw blade fixed on an arbor revolves at a very high speed. The work-piece is fed against the rotating blade to make the cut. Circular saws, much like table saws, are a very common workhorse in both professional and DIY workshops. A circular saw is a versatile tool that offers high portability. The main purpose of a circular saw is to cut wood and other soft materials; in this sense, they are essentially portable table saws. You can also this saw to cut tough materials like metal with the appropriate circular saw blade. The working principle of a circular saw is opposite of a table saw. How Circular Saw works: A circular saw it a handheld power tool with a rotating blade that is pushed across the workpiece to cut through it. That means the work needs to be stationary and the rotating circular saw blade moves to make the cut. Jigsaws work similarly to reciprocating saws, except with two key differences. Firstly, unlike with regular reciprocating saws, the blade on a jigsaw aims downward, instead of jutting out from the nose of the saw. Secondly, jigsaws are designed specifically to make curved or otherwise non-straight cuts. A jigsaw, when compared to a reciprocating saw, is a much more precise tool. Also, it is the only handheld power saw with which you can produce curved cuts. Uses of Jigsaw: The jigsaw is a very versatile tool that can be used to cut straight and curved cuts on different materials including wood, plastic, metal, granite, tiles, and metal. One of the most common applications of a jigsaw in a household is to install countertops. Another advantage of a jig saw is that you can use it to cut internal profiles. All you need to do is drill a start hole for the blade to enter and you are ready to cut straight, angled and curved shapes. Introduction of Grinding Machines Grinding machines produce flat, cylindrical, and other surfaces through high-speed rotating abrasive wheels. Grinding is a means of giving a more accurate finish to a part already machined but is also a machining process in its own right. The main types of machine are the ‘surface grinding machine’ for flat surfaces; and the ‘cylindrical grinding machine’ for cylindrical surfaces. More complex shapes are produced by shaped wheels called ‘contour grinding wheels’. ‘Bench’ and ‘pedestal’ grinders are used for tool sharpening, etc. A grinding machine, often shortened to grinder, is one of the power tools or machine tools used for grinding, it is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation. Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension. As the accuracy in dimensions in grinding is of the order of 0.000025 mm, in most applications, it tends to be a finishing operation and removes comparatively little metal, about 0.25 to 0.50 mm depth. However, there are some roughing applications in which grinding removes high volumes of metal quite rapidly. Thus, grinding is a diverse field. There are also drill machines.

Why Aluminum Windows

Descripción: Aluminum windows and aluminum doors have become increasingly popular for both commercial and residential buildings. Aluminum window frames can be made to match almost any color and home style. They can also be made in a range of different configurations including casement windows, double-hung windows, sliding windows/doors, awning windows, fixed windows, and lift and slide doors. Here are some reasons why you should choose aluminum. Durability Aluminum windows are far less prone to warping; they are weather-proof, corrosion- resistant and immune to the harmful effects of UV rays, ensuring optimal performance with a long lifespan. Their strong window frames will last longer than wood and vinyl frames. Variety of Color Options Aluminum windows can be powder coated or anodized in thousands of colors. The only limitation in color is your imagination. Energy Efficient Because aluminum, including aluminum awning window, aluminum sliding windows, aluminum casement window, etc., is light, malleable and easy to work with, manufacturers are able to produce window frames that offer high levels of wind, water, and air-tightness, which means exceptional energy efficiency. Cost efficient Aluminum windows are far less expensive than wood frames. They do not leak; therefore, they can save a ton of money on energy bills. Low Maintenance As opposed to wood, aluminum does not warp or decay. Additionally, paint touchups are not needed. Aluminum is strong enough to bear the load of window lintels with minimal reinforcement. Aluminum windows are virtually maintenance free. Better Operability Aluminum is a durable substance and will keep its shape over time. Therefore, aluminum windows and doors will continue to open and slide smoothly over the years. Noise Proof Aluminum windows are much better at stopping noise than vinyl windows. Since they are three times heavier and many times stronger than Vinyl. Also, aluminum windows are best when you're opting for the soundless feature due to the fact that they can support heavier glazing than other solutions. Safety Features The linkage hardware around the window sash and the handle operating make the window have excellent safety and security. Also, aluminum windows are highly resistant to forced entry and have high-quality multipoint locking mechanisms, which makes it impossible for people to break-in. Why do you really need an aluminium toilet cabinet? It is always a difficult thing for people to choose a bathroom cabinet. This is because there are so many styles, designs and functions of cabinets that are available in the market. Choosing the material for your cabinet too may be a little hard since you want to go for a material that is durable, stable, long-lasting and at the same time will give you what you want. Aluminium bathroom cabinets are very popular in most modern homes. They are available in various designs, styles and shapes in order to suit any toilet. The fallacy that aluminium cabinets are very costly does not really hold again these days because there are cheap aluminium cabinets that you can find in the market although the prices of aluminium cabinets may be slightly higher than the other cabinets. Aluminum toilet cabinets and aluminum kitchen cabinets have various advantages that will entice you into having them as your bathroom cabinets. Aluminium toilet cabinets are durable Of all the materials that can be used in making cabinets, aluminium remains the best. You would have realized that your bathroom is always covered with moisture and warmth from the hot air that comes as a result of your shower. Aluminium is the only material amongst all other materials that can fully withstand both moisture and warmth. It will do this effectively without being affected by it. Not only that they are durable, but they also have a tough and robust nature when placed in comparison with other materials used in constructing bathroom cabinets. Aluminium toilet cabinets (or aluminum laundry cabinet) have lasting performance Do you know that aluminium cabinets can last for a lifetime? Yes, they can and the reason behind this is their thickness and framework. Thick aluminium cabinets provide better support and they do not bend or become deshaped unlike cabinets made with other materials. Although some deformities may be noticed with aluminium cabinets. These deformities may be slanting or tilting of the cabinet with time but this will only be noticed with cheap and low-quality aluminium and that is why I advise you to go with high-quality aluminium when you want to buy a cabinet. Aluminium toilet cabinets have a quality of being waterproof. One of the major problems that are noticed in bathrooms and toilet is the condensation of water vapour on surfaces and materials in the bathroom This condensation will lead to the formation of moisture on these surfaces. Moisture is a very big threat to wood cabinets because it may cause the wood to twist or bend in shape or swell. When this happens, the area that has become damaged will be unable to support heavy loads and the cabinet becomes eventually useless. Aluminium cabinets defy this mechanism because they are waterproof. Moisture from the condensation of water vapours or other things in the toilet will not harm them and they will not be susceptible to bending or swelling from any moisture.

WHAT TOOLS ARE USED IN LAPAROSCOPIC SURGERY?

Descripción: Laparoscopic instruments are made of durable materials and usually high quality stainless steel. Instruments all have a very narrow shaft so that they can fit inside laparoscopic ports. Sizes typically range from 3 mm, 5 mm and 10 mm sizes. A variety of tips are available for manipulating the tissue and handle styles may allow ergonomic rotating, grasping and locking abilities in a precise fashion. Laparoscopic instruments are used along with a laparoscope, which is a thin telescope fitted with a cold light source and a video camera. Inert gases like carbon dioxide are used to inflate the abdominal region which increases the distance between the organs and the abdominal wall thus enlarging the operating field. Common instruments used during laparoscopic procedures include a: LAPAROSCOPE, NEEDLE DRIVER FOR SUTURING, TROCAR, BOWEL GRASPER and SURGICAL MESH. LAPAROSCOPE Surgical scopes are one of the oldest instruments used by medical practitioners since ancient times. Modern surgical laparoscopes used for minimally invasive procedures are a far cry from the simple hollow tubes that gradually developed to include lenses for magnified vision. Today, scopes are more like an apparatus with multiple parts that include a CCD camera, viewing device, lens cleaner, and an energy-supply device. NEEDLE DRIVER A needle holder is used by laparoscopic surgeons to hold suturing needles when closing wounds. Forming slip-knots to close wounds and surgical incisions requires precise skills. Suturing can often be tricky to use owing to the property of “memory” which causes tissue to resist deformation. Needle holders have three parts – the jaws, joints, and handles. The instrument, including disposable laparoscopic instruments and reusable laparoscopic instruments, is classified as straight or curved depending upon the shape of the jaws. TROCAR Along with the probe, scalpel, and cannula the trocar is one of the oldest implements used by medical practitioners. A trocar is shaped like a pen and has a sharp triangular point. Trocars are typically placed inside hollow cannulas and introduced inside body cavities to assist in draining fluids. Trocars are now referred to as both the initial entry device as well as the hollow cannula used during the operation. These instruments play an important role in laparoscopic surgery. Instruments such as scissors and graspers are introduced using surgical trocars. BOWEL GRASPER A bowel grasper is used during minimally invasive bowel surgery. The graspers are maneuvered through incisions that are usually no larger than 5 mm. The advantage with using laparoscopic graspers is that they enable the surgeon to grasp and manipulate abdomen tissue with precision without having to cut open the abdomen. The graspers facilitate observation, excision, and biopsy procedures. SURGICAL MESH Hernia mesh is an implantable device that serves as scaffolding for your natural tissue to grow into and hence reinforce the area. The mesh itself only provides minimal support. It is your own tissue that is ultimately responsible for the repair. There are many different types of surgical mesh that can be used to repair hernias and other defects of the musculoskeletal system. The journey of laparoscopy, which is now reaching single-incision and robotic surgery, began with our quest to find ways to reduce operative morbidity.1 Since those first steps were taken, gynaecological surgery with the use of minimally invasive techniques continues to change rapidly. With computerised design and microchip-controlled safety features, the laparoscopic surgeon is dependent on the equipment and needs to understand the electromechanical function of the instruments. In this changing environment, it is vital to understand the characteristics of the commonly used surgical instruments. The basic equipment essential for any laparoendoscopic procedure includes: endoscope, camera, light source, video monitor, insufflator, trocars and surgical instruments. However, there are many variants of each available Disposable or reusable? The cost effectiveness of disposable versus reusable instruments is a subject of debate. The choice of the instrument is multifactorial and depends on function, reliability and cost. So, during most laparoscopic procedures, a combination of disposable and reusable instruments is used. Frequently, disposable trocars and scissors are used, while reusable instruments can be graspers, coagulation spatula/hook and needle drivers. The commonly used laparoscopic instruments are described below. Uterine manipulators These allow uterine positioning and expand operating space. Several uterine manipulators are available – the HUMI? (Cooper Surgical), the RUMI? (Cooper Surgical), Spackman, Cohen, Hulka, Valtchev, Pelosi and Clearview? (Endopath). Some are reusable while others are disposable. Most come with a channel to perform chromotubation; however, some (such as Hulka tenaculum and Pelosi) lack this channel. With 210?, Clearview has the greatest range of motion in the anterior-posterior plane. Hulka tenaculum, Spackman’s and Cohen’s have a straight shaft, hindering their range of motion and limiting their use in advanced laparoscopic accessories and procedures. Veress needle This is a specially designed needle with a blunt-tipped, spring-loaded inner stylet and a sharp outer needle, used to achieve pneumoperitoneum while performing closed laparoscopy with ultrasonic system. It is available in disposable and reusable form, with 12cm or a 15cm length. Most injuries in minimally invasive surgery are associated with primary port insertion, leading to an unresolved debate on the benefits of various entry techniques (open, closed or direct entry). There is no evidence that any single technique is better in preventing major vascular or visceral complications, though there is a higher risk of failed entry with closed entry. The most recent Cochrane review concluded there is a lower risk of vascular injury with the direct entry in comparison to use of Veress needle.3 Trocars/cannulas These are used to create small passageways through the abdominal wall and are available in different textures (see Figure 1). Disposable and reusable trocars in various sizes are available and share the following common parts: Sharp tips cut an entry path through the abdominal wall while blunt tips stretch the tissues apart to gain access to the peritoneal cavity. Sleeve: is the working channel. Trocar sleeves or collars can have textures on the outer surface of the trocar that help it anchor to the abdominal wall. Some have an internal inflatable balloon at their tip and plastic/rubber ring to provide anchorage. Valve: different valve systems prevent gas leaking from trocars and allow the insertion of instruments. Side port: many trocars come with a side port that allows for gas insufflation or smoke evacuation. Laparoscopes The telescopes used in laparoscopy are available in sizes ranging from 2mm up to 12mm. The 10mm size is the one most commonly used in gynaecology. Similar to a hysteroscope, a laparoscope can come with an angle of view such as 0?, 30? or 45?. In an angled-view scope, the direction of vision points away from light source attachment. The 0? telescope offers a forward view corresponding to the natural approach and is preferred by most gynaecologists. It is useful if a less-experienced assistant is available. The 30? telescope can be rotated to enlarge field of view and can be advantageous for complicated cases. The 45? telescope is useful in single-incision laparoscopies, but is not commonly available. Every laparoscope has an engraved number by the eyepiece that specifies the viewing angle.

HOW DIGITAL PRINTING WILL IMPACT THE QUILTING COTTON MARKET

Descripción: Quilting with machine embroidery is an easy way to finish off the top of a quilt or be creative with quilt blocks. With the popularity of personal embroidery machines increasing, many quilters find it cost-effective to quilt their own projects instead of sending them to a professional. Also, for those who quilt by hand, this process can get the job done in a fraction of the time. Quilting With Machine Embroidery Basics While quilting with machine embroidery may sound cumbersome, it doesn't have to be if you follow the instructions and have the correct embroidery supplies. This style of machine quilting falls into two categories: Machine guided: This technique, which uses your machine's feed dogs, is for straight and slightly curved lines. It is used with a walking foot and sews about 12 stitches per inch. Free motion: This type of quilting, where the feed dogs are dropped or covered up, normally doesn't follow straight lines. You can use different feet with it, but a darning foot works well. This foot jumps up and down with the needle, allowing you to easily move the fabric. Supplies and Accessories Quilting and embroidery supplies and accessories vary depending on your machine and the type of quilt you want to design. Some of the basic tools needed are: Sewing or embroidery machine Embroidery patterns Needles Thread Bobbins Gloves or grippers Embroidery hoops (if they don't come with your machine) Spray adhesive Darning foot and other embroidery machine feet Quilting stencils Designs Available Online There are many helpful Web sites where you can buy or download for free many different printed quilting and embroidery designs. For example: Embroidery Online offers a wide choice of delicate and beautiful quilting designs for purchase. Erica's Embroidery Designs has both simple and complex designs. Splinters and Threads has some basic patterns for sports, feathers, and other miscellaneous designs. Golden Threads motto is, "Designs that make every embroidery quilt a work of art," and the ones listed on the Web site show just that. Everything from complete quilting packages to miniature designs is offered. Advantages and Disadvantages Some will find quilting with machine embroidery a breeze, while others won't like it all. Pros There are many advantages to embroidering a quilt in this fashion: It cuts back on time it would take to hand-embroider the item. It can be cost-effective because doing the microfiber printed quilting at home is cheaper than having a professional do it. Learning a new craft may be hard work, but it is fun. Cons While every quilting technique has an upside, it also can have a downside: Quilting with machine embroidery does not work with every style of quilt, like jacquard quilt. Making a mistake can be costly, especially if the machine snags, rips or puckers the fabric. If you are a novice quilter, a professional can embroider your quilt quicker and more efficiently. Tips for Quilting With Machine Embroidery If you are using a basic sewing machine, the easiest way to get the design onto your quilt is to trace it onto tissue or other lightweight paper. Pin the paper to the quilt and sew on the lines. Tear the paper away when you are done. Add a folding or cart table next to your sewing table to help support the heavy quilt. Practice on scraps pieces of fabric before quilting your final product. If you are a beginner, take a digital printed quilting class from your local craft store or community college. Michael Miller Fabrics will begin printing the majority of its quilting cottons digitally in 2019. The shift from screen printing to digital printing is one that Michael Steiner, the co-owner and company president, has been contemplating for a while. “We’ve been printing a small percentage of our quilting fabric digitally for three years now,” Steiner said in a phone call from the Michael Miller warehouse earlier this week. “And all of our plush fabric is printed digitally. Digital printing is not the only path forward, but it’s definitely a path that offers more flexibility for us.” Until now manufacturers of premium quilting cottons, the kind of fabric sold through independent quilt shops which sell patchwork printed quilt, ultrasonic quilt, winter quilt, etc., have been printed with flat-bed screen printers through mills in Korea and Japan. Screens are engraved for each color in the design, then ink is pushed through a frame screen onto the fabric, like a stencil. The quality and colorfastness of the prints are high, but there are limitations. A screen can only hold about two dozen colors and the repeat can only be 24 inches wide, the size of the screen printing bed. The process creates dye and water waste. There’s about an eight-month turnaround time from the time the designs are submitted to the time the fabric is in the warehouse. And the mills require an 800-1,000 yard minimum order for each colorway. There are also no high capacity flatbed screen printers for textiles left in the US. THE DIGITAL ALTERNATIVE For at least a decade digital fabric printing has been lurking as a possible alternative. The print-on-demand fabric company, Spoonflower, was founded 2008 giving consumers a taste of digitally printed fabrics. Today, most of the major manufacturers of quilting cotton have done some digitally printing fabric, at least on an experimental basis. But now, several of the major companies are going all in. (Watch the digital printing process in this video from Hoffman California Fabrics.) Last year Ken Gamache at QT Fabrics decided to shift all of the company’s fabric to a digital printing plant in China. Gamache says the plant he’s found can produce 18 million yards a year and has just invested in a second printer. The trade tariffs on Chinese goods that could be implemented in the coming months will impact QT in a way that they won’t affect other quilting fabric companies, but Gamache feels the decision was likely the right one anyway because it affords him the ability to better control QT’s inventory, plus he loves the quality of the designs digital printing can produce. CAPACITY AND PRICING Right now there are digital printing plants in China, Korea, Pakistan, Japan, Italy, and even in the US at Santee. The Korean mills haven’t yet invested in the high-speed digital printers so their cost is still very high. Others can offer fair pricing, but can’t produce the necessary volume, but they’re getting there. THE CREATIGVE ADVANTAGES OF DIGITAL Hoffman California Fabrics has embraced digital printing, becoming known for their digitally printed fabric panels. “We can quite literally create anything and turn it into fabric without any limitations on color or problems with overlapping motifs,” says Hailey Hoffman-Chisholm, Marketing and Sales Associate at the company. “We can capture thousands of colors and achieve photorealistic designs on cotton.” Still, there are some color limitations. According to Steiner, digital printers can’t print metallics or pigment white. Hoffman has gotten creative with product development, using limitless size for repeats to their advantage. They’ve designed large panels and now bolts that are two-yard panels with eight different fat quarter-sized prints. For Hoffman, the cleaner printing process is also a priority. “Textile manufacturing is not good for our planet, and the digital printing process is by far the most eco-friendly form of textile printing that has come about,” Chisholm says. “We believe it is the right way to print and where textile manufacturing will go as a whole.” LESS RISK FOR REPRINTS Digital printing allows fabric companies to be more nimble when it comes to reprints. The large minimums screen printing requires can make companies hesitant to reprint a design or collection, even if sales look promising. The four times a year release cycle that has become industry standard means companies can easily become saddled with excess inventory that ends up being sold at a loss in closeout sales. Digital printing, on the other hand, offers lower minimums. “Technically the minimum is 5 or 10 yards,” Steiner at Michael Miller says, “But really we would produce 500 yards of each design.” That level of investment is easier to make. Fabric that sells well and gets reprinted benefits designers, too, because they continue to earn royalties on the designs that have proved to be most successful. Steiner explains, “There’s no benefit in producing something that’s not going to sell. If we print 2,000 yards and sell 800, then closeout the rest, that doesn’t benefit the designer.” Digitally printed fabric continues to cost somewhat more to produce, at least for now, which leads to a higher wholesale price. This means designers will also see slightly more money per yard sold. WHERE WE’RE HEADED In the years to come the quilting industry will likely see more companies follow in QT and Michael Miller’s footsteps, shifting the majority of their operations to digital. “I think it’s good for the whole industry,” says Steiner. “Less glut in the market, less excess fabric floating around clogging things up and inhibiting new product development.”

Dog Beds: Everything Pet Parents Need To Know

Descripción: Dog beds can be simple or fancy, expensive or homemade, and everything in between. How do you pick the right dog bed for your pup when there are so many on the market? Does your pooch even need a dog bed? Should you spend a lot of money when your dog is just as happy lying with you in your human bed or on the couch These are all questions you should consider before you buy a dog bed, and this dog bed guide is here to help you make a decision. Does Your Dog Need A Dog Bed? Even if your dog is allowed to sleep with you in your human bed, every dog should have a bed of their own — or two or three or four, actually. There are plenty of benefits to having dog beds. They can be used for napping during the day and sleeping in at night. Unlike the floor, a bed will keep your dog warm, support arthritic joints, and prevent calluses. And unlike a couch or human bed, dog beds, or pet bed, are spaces that pups can have all to themselves. And if you’re allergic to your dogs, then it’s best if they sleep somewhere besides your bed. Dog beds can also be taken with you when you travel so that your dog feels comfortable and is able to sleep somewhere familiar. They’ll rest easier and feel less anxiety. Dog beds are also usually easy to wash, which makes life easier if your dog has accidents, gets infested with fleas or mites, or just rolls in something stinky. A dog bed shouldn’t be used as a place for punishment or confinement. It’s a place of security that belongs only to that one dog, and they should always feel safe in it. A bed makes a crate more comfortable, but that doesn’t mean a dog can spend twelve hours a day in a crate just because it has a bed. It’s a place dogs should be able to go and relax without feeling trapped or anxious. All dogs could benefit from having a place where they can feel calm and de-stress during the day or night. What Kinds Of Dog Beds Are There? Dog beds can be as simple as your old pillow or as fancy as a wrought-iron frame with a lace canopy. Your selection depends on your taste, budget, and décor, but you may find that your dog expresses a preference by taking over another dog’s bed. Keep an eye on where your dog feels most comfortable, as this can help you decide which bed will be best. Basic Styles Of Dog Beds Flat pads or mats are inexpensive and fit in crates. Nesting/snuggle beds are similar to beanbag chairs and often preferred by smaller dogs who love to curl up. Cuddler/nest beds come in the “traditional” oval bowl shape. Bolsters have one long side with a built-in pillow and are often preferred by large dogs. Donut-shaped beds are circular bolsters with a removable center pillow. Waterproof beds are good for outdoor use or incontinent pets. Homemade beds can be inexpensive and easy to customize. There are plenty of tutorials on how to make your own dog bed with blanket that you can find on YouTube or by searching online. Just make sure you’re using safe materials and that it will hold up, especially if your dog likes to chew. Special Dog Beds For Seniors Or Dogs With Medical Needs Orthopedic beds support old joints or very large dogs; they usually have medical-grade foam and/or box-spring construction. Heated beds maintain body warmth. This can be beneficial for dogs who get cold easily or for dogs with arthritis that is worsened by the cold. Travel beds are portable, so your dog can have the security of the same bed every night while on the road. For dogs who suffer from anxiety in new places, this can help them relax and get some sleep. Cot-style beds keep your dog off the ground and comfortably support joints by distributing the dog’s weight evenly. They are also usually fairly easy to transport. What Is The Best Dog Bed For Your Dog? There are so many dog beds on the market. How do you pick the best one? There are many factors to take into consideration, including size, cost, comfort, your dog’s medical needs, convenience, and so much more. You should do your research and consult your veterinarian about your pup’s needs before you make a decision. Here are several factors to consider when choosing the best dog bed: A good fit. Beyond finding something within your budget, make sure your dog fits on the bed; heads and limbs shouldn’t have to be hanging off the edge. Easy washability. Dogs eat treats, vomit, pass gas, scratch fleas, and wipe ointment-filled eyes and ears on their beds. Some dogs urinate on them — so the ability to throw the bed into the washing machine is a big help, if not downright critical. Dogs with allergies will also benefit from having their bed washed frequently. Safety. Place the bed away from high-traffic areas so no one trips on it or on the dog. If the dog chews it, then get rid of it — swallowing stuffing can lead to emergency surgery (and you thought the bed itself was expensive). Remove any buttons or ribbons the dog could chew, or look for “chew-proof” beds now available. Stuffing that works for you and your dog. Young, warm, healthy dogs can usually get by with inexpensive foam filling, but your older or arthritic dog will probably prefer more comfort and support. Some orthopedic beds use foam because it’s thicker and of higher quality, so it doesn’t squash flat. Thick, flexible gel has recently become more common as a bed filling; it’s more comfortable than foam and distributes weight more evenly, making it excellent for geriatric dogs — but expensive. And some beds contain cedar chips to ward off pests and keep the bed smelling fresher than your dog. The environment. Some of us are concerned about using materials that won’t harm the earth when we decide to replace, get rid of, or recycle a dog bed, or a car tree. You can check out eco-friendly dog beds if that’s something that factors into your decision. Absorbent pads for dogs who wet the bed. Sick, incontinent, or geriatric dogs can benefit from washable or disposable absorbent pads (technically, you’re the one benefiting because you won’t have to wash the bed). Note: These flat pads won’t fit well in a nesting bed.

How do I use a Recovery Strap?

Descripción: The right recovery straps and how to use them can make the difference if you can pull your vehicle out safely or if you have to wait on a tow truck. A high-quality strap without hooks attached to it is the strap you want to use for getting a vehicle unstuck. The above is called a “tow” strap. The main reason not to use this for recovery is simple. If the recovery strap or your recovery hardware breaks, it’s not safe to have a metal hook flying off at speeds in excess of 100 mph. Many people have been killed and seriously injured by using these straps incorrectly. These straps will not stretch because they are made for towing, not recovery. How a Recovery Strap Works The strap works like this. Say for example you are pulling out your friend, so you attach your recovery ropes to the back of your vehicle and then to the front of his. As you drive away from him the recovery strap stretches just like a rubber band. The strap wants to go back to its normal size, so it has no other choice than to transfer the energy to the stuck vehicle, pulling it out. Recovery straps are flat with sewn loops and no hooks. They are nylon, not polypropylene or Dacron or chain. Because the straps are made of Nylon, they stretch. They are safer than chains, easier to use, and not nearly as heavy. Specifications I’ve seen recovery straps come in lengths of 20 to 40 feet and widths from 2 to 6 inches. A general rule of thumb, each inch of width will allow you to pull out about 10,000 lbs. So if I have a 3 inch wide strap, it would be rated to tug up to 30,000 lbs. Many will then ask, why not go all the way up to a 6″ wide recovery strap? The problem is that the strap becomes less elastic the wider it gets, which means it will not work properly. Typically a 2″ or 3″ wide recovery strap will suit all of your needs. Tips for Recovery Strap Use Before ever using the strap, make sure it is in good condition ( no cuts, frays, or broken stitching.) Make sure the hardware being used is free of defects and rust. This includes your tow hooks or front hitch and the hardware on the other vehicle. If possible, the recovering vehicle should place the recovery kit strap to its rear end, which would be the safest place if the strap happens to break. You may be able to wrap the strap around a hitch, but I would not put it IN the hitch. I have seen a few people who have bent the pin, which then had to be cut out. Getting a tow hook or D-Ring adaptor to go into the hitch is a better idea. Here is an example of a D-Ring adaptor and how a recovery gear strap should be hooked up to one: Some older cars actually have tow hooks, but if not you must use your own judgment. Never attach a recovery strap to a vehicles bumpers, axles, suspension, steering rods, or a trailer hitch ball. The attach points must be to a secure place on the vehicles frame. Do not place the recovery strap on another vehicle in a way that it may be cut. Never, ever, attach a recovery strap to another vehicle with a knot. You should pass one end of the strap through the loop at the other end of the strap to secure it on. Incase the strap may break, lay a tarp or some jackets on top of the recovery strap. When the strap breaks (lets hope for the best, but prepare for the worst), the jackets or tarp will slow the recovery strap down before it hits someone. To help protect the strap from tears, make sure all logs and large rocks are removed from the recovery path. Everyone should stand clear of the recovery strap when it is in use. When pulling the vehicle out, drive very slowly. Sudden tugs may lead to damage to either of the vehicles or the strap accessories. Once the vehicle is safely removed, inspect your recovery kits strap and hardware and hit the road! In addition to these recommendations, read the instructions your recovery essentials strap comes with. To protect your strap, store it out of sunlight and away from heat and keep it clean. Dirt, mud, and debris embedded in a tow strap actually damages the fibers over time and can decrease its strength. After a muddy day of wheeling and recovery, always clean your straps by hosing them off and spray horizontally across the strap as not to push the debris into the strap fibers. Happy Recovering!
