Over the past few years, body sculpting has become quite popular across the globe. According to some experts, these treatments can help you eliminate fat cells so you can get back in shape and appear slimmer. In this article, we are going to read about some common body sculpting treatments and their advantages. Read on to find out more.

The shower answer is, yes. These treatments may help kill fat cells and cut down on the amount fat on the target areas of your body. You can use ultrasound, cooling or heat method for this purpose. The results may take a few months to appear.

Basically, this type of treatment helps shrink the fat cells. It may also kill some fat cells and they will be gone forever. It’s important to keep in mind that body sculpting is a simple weight loss treatment. You can go for it if you want to maintain your lifestyle using diet and exercise. Let’s talk about some common treatments.

1. CoolSculpting

This treatment is approved by the FDA. Also called cryo lipolysis, this treatment causes the fat cells to freeze in the target areas. After the cells are frozen, you will see that your body is getting back into shape over the next few months.

Most patients who get the treatment experience a reduction in body fat in a few months. The good news is that the results of the treatment are permanent.

Pros

You can use the CoolSculpting method on almost every part of your body. Therefore, if you want to target several parts of your body simultaneously, you can go for it. If you want to target only one area, you need to wait for at least 30 minutes before the procedure is done.

2. WarmSculpting

Unlike CoolSculpting, WarmSculpting makes use of the heat of lasers to eliminate fat cells. As far as the process is concerned, it follows the same method that involves targeting and killing fat cells in your body.

Also, for some parts of the body, it’s approved by the FDA. After the treatment is done, you will experience reduced body fat in the target areas.

Pros

This treatment is a good choice for those who have stubborn fat in some areas of their body. The good thing is that the results of the procedure are permanent provided you take the right steps to maintain your physical health and ideal weight.

3. UltraShape

UstraShape uses ultrasound energy to target fat cells. Basically, the treatments kill fat cells and expel them from your body like natural fat. Also, it’s approved by FDA and you may experience great results after three months.

Pros

According to a clinical study, all patients find the treatment comfortable. This is what makes this procedure better than other treatments out there. You don’t feel any pain or even slight discomfort. Plus, the treatment is free of all types of side effects like bruising or skin redness.

Long story short, these are just some of the most common body sculpting treatments. If you follow these treatment methods, you can get rid of that stubborn body fat and get back in shape once again.

By the name, it is quite understood that cold & hot rolled steel hold some differences. But it is not due to the difference in their grade or specification, it is due to how they are treated inside the mill or factory during the manufacturing process.

Hot rolled steel utilizes the high temperatures to roll the steel, whereas, steel is processed in cold temperature once it is off with the annealing (heating element & allowing it to cool slowly) process.

What is Hot Rolled Steel?

• It is prepared by rolling the steel at a high-temperature point (usually 1700 degree F) which is even beyond the re-crystallization temperature of the steel.

• Once the steel reaches beyond its re-crystallization temperature, it gets easy to shape, mold or form the steel into larger sizes.

• This type of rolled steel is cheaper comparative to old, as it doesn’t require re-heating or any further process.

• However, this type of rolled steel doesn’t give much scope to manage the size & shape of the material – once it cools off & shrink as compared to cold.

Uses of hot rolled steel

This type of steel is utilized in the making of steel bars for making railroad tracks & I-beams by the welding & construction settings. This type of steel fits best in product engineering where there is not much need for précised shape & tolerance.

What is Cold Rolled Steel?

• It is basically the extension of hot rolled steel – the one which has been further processed.

• The steel is later processed inside the cold reduction meals and when the material is cooled enough it is again heated and brought slowly to the cooling point with help of the process annealing.

• This process makes the steel have finished surface & close dimensional tolerances.

• The process is followed by “cold finishing” which involves 4 steps – cold drawing, Turning, Grinding and Polishing.

• These four stages are performed as each has its own advantages. Cold drawings discard the need to have costly thermal treatments and increases the tensile strength & yield of the material. Turning helps to scrape out the imperfections from the surface. Grinding helps to narrow the tolerance range and polishing helps to bring the surface finish to the finished product.

• The cold is in demand over hot rolled one as it brings superior surface finish, tolerance & straightness to the product.

Uses of Cold Rolled sheet

It fits well to the project requirements where there is immense need of surface condition, concentricity, tolerance and straightness.

So, these were the few factors of hot and the Cold Rolled sheet that makes them different from each other.

Precious Slag Balls are widely used as abrasives for industrial applications. They are made by a process that involves the atomizing of liquid steel slag using a modern technology called Slag Atomizing Technology (SAT). The liquid steel slag stream is converted to spherical slag balls of various sizes by super cooling method of molten slag, using fast heat exchange of the falling liquid steel slag in a high speed airflow. During this process, free CaO and Fe2O3 are scattered to form a solid PS ball and thus produced is in a stable Spinel Structure.

Characteristics of PS balls

– They are environmentally friendly as the material is pollution-free and non-toxic.

– Has a natural characteristic hardness.

– Is not toxic due to properties caused by its structure, shape, physical and chemical compositions.

– Its Spinel structure causes stability in physical and chemical composition, eliminating any causes for pollution.

– As compared with sand, it has superior characteristics in compressive strength, hardness and anti-weathering properties.

– PS Ball is a cost-effective material as compared to other mineral materials.

– The efficiency of the abrasive material makes it easy to recycle, reducing the consumption rate and increasing the productivity. It can be recycled up to 3-4 times depending on the surface hardness.

– This material is easier to produce and supply, as compared to copper slag and garnet mineral abrasives.

– Storage is easy.

– Lower levels of dust and contaminants make it less risky for use in various field operations, and less harmful to the health of operators.

Applications of PS balls

Unlike the case of mineral abrasives like garnet, PS ball is completely dust free and this makes it suitable for use in surface preparation, rust removal and ship building applications. It is also commonly used for maintenance of ships.

PS Balls find applications in oil storage tanks, bridge construction work, in construction of heavy steel structures, in oil rig platforms, and so on; mainly for purposes of cleaning and surface preparation and are used for cleaning welded areas in storage tanks before repainting.

It can be used as an abrasive material, to clean material surfaces and prepare them for painting.

The typical characteristics make PS balls perfect for use in blast cleaning applications, as they provide the right atomizing of materials with respect to size, density, hardness and durability.

Due to its high bulk specific gravity of 2.42 Kg/l, precious slag balls are widely used as a counter balance in many applications.

PS ball is also used as a filtration medium as it is non-water absorbent and is very durable.

Because of its nonslip properties, PS Balls can be used as covering on the road or as paving for concrete and asphalt roads. It adheres effectively with asphalt or concrete, and can therefore be used as efficient repair or reinforcement material for various purposes.

Pharmaceutical companies are on the rise today. The industry is booming with high ratios of dependency of the patient. The agenda of these companies is to prepare a medical drug to either use or sell it through appropriate means. They deal in generic or brand medications and devices but are bound by various restrictions on the sale and purchase of them. They are subjected to only lawful means where the product should be fully tried and tested. We, as a rising pharmaceutical agency strive and put our energy and focus so that we can provide our patients with the best. Companies like us go through a series of steps on the ladder of providing fully trusted products.

The easiest phase of all is the Operational qualification (OQ) phase as it is considered a walk in the park. During this process, there is the absence of any kind of load due to which giving accurate results is not an impossible task but these results cannot be trusted upon as they show only one side of the story. The next step is the Installation qualification (IQ) followed by Design qualification(DQ). These steps are not of much importance. The most important and crucial phase during the testing of a product is Performance Qualification (PQ). It is undeniably the only source that accurately describes whether the product is viable at all.

For instance, if we consider a homogenizer working perfectly when empty but doesn’t provide a specified rate per minute with a few kg of weight in it, then it will pass the operational qualification test but will fail in PQ. The testing is asked to verify that the performance specified in the user requirement specifications is being delivered. It is also mandatory to confirm the requirements listed in government protocols, health and safety rules and other guidance documents. For pharmaceutical companies, the objectives of the test and methodologies must all be pre-approved. It showcases the final qualification of equipment. This includes a wide range of tests to restore the production and give assured results that your system is capable of process validation activities.

If our products don’t go through PQ then they might end up in a horrid condition where it may even produce an undesired product that might harm a large group of people. We are bound by an ethical obligation in which we want to provide our customers with quality results. If these tests fail then our reputation is at stake which is highly non-acceptable by our company. Performance qualification is as mandatory as it is for a human to breathe and the time to move. If you purchase a new air conditioner, you tend to inspect it from every single aspect. Statistical programmers in the pharmaceutical world are key players in all area of research about drugs and medications from the initial progress of a chemical right to the manufacturing and commercialization of these products.

You set it on every single mode to check its cooling process, you call in for a demo to understand the system better, but does the air conditioner always works the same for years? Does it provide the same amount of cooling for the whole day? These are the questions which are answered by Performance qualification in pharmaceuticals companies related to their research on medicines. For achieving success we need to continue working hard so that the end results are complimenting the struggle to receive the best out of all.

Wine cellar cooling systems are designed specifically to maintain a constant temperature between 55 to 57 degrees Fahrenheit and humidity levels between 50 to 70 percent. The right humidity levels will keep your corks moist and swollen enough thus ensuring a tighter seal while the right temperature moderates your wine’s aging process.

Always keep in mind:

• If humidity is too low, you dry out the corks, thus allowing air to slip into the bottle and if oxidation occurs, the wine will surely be ruined.

• If humidity is too high, you risk growing mold in your corks, labels and wine racks.

• If the temperature is too cold, the wine becomes dormant and would end up tasting flat instead of being fruity and sparkling.

• If the temperature is too high, you risk cooking the wine and aging it prematurely.

Ideally, however, the cellar room itself should be designed and constructed precisely with the right conditions for these temperature and humidity variables to work.

The Wine Room

Before installing a wine refrigeration system, make sure the room is vapor sealed and properly insulated.

• Every wall and ceiling should be scaled with a vapor barrier on the “warm side” of the walls. 6 or 8 mil plastic sheeting is highly recommended.

• Interior walls should be insulated to a minimum of R-19. We recommend using rigid foam board. Additionally, all cracks should be filled with expanding spray foam.

• All walls are finished with moisture resistant green board.

• Doors should be solid wood and/or insulated and weather stripping is vital for an air tight seal.

• Glass should be double pane with a minimum of a 1/2″ gap.

• Lighting should be low wattage.

The Wine Cellar Refrigeration Units

Wine cellar refrigeration unit types and models are usually chosen based on room size, which is usually measured in cubic feet (Length x Width x Height). Other factors to consider are the location of your wine room and the geographical aspects of your home because they can affect the temperature and humidity of your wine room. Measure the size of the room then use a thermometer and hygrometer to test the room’s natural temperature and humidity.

You can now choose your wine cellar refrigeration system based upon your results. There are mainly 2 types of wine cellar cooling units.

The first is the relatively more affordable Self-Contained Cooling System. The self-contained cooling system is a lot like a built-in or through-the-wall air conditioning unit. This system needs to vent to an adjacent climate-controlled room that is usually the same size or larger than your wine room. The WhisperKool XLT Series is one example of a self-contained cooling system.

The second type is the Split Cooling System. This type of wine cellar cooling unit is essentially two separate units, the condenser unit and the evaporator unit. The condenser, which is usually situated outside the house, supplies refrigerant liquid to the evaporator via a compressor, which is normally wall mounted inside the wine room. The evaporator then cools the air that comes into contact with it by turning humid air into liquid, which is then collected outside the wine room.

Split Cooling versus Self-Contained Cooling

Self-contained systems are less expensive and simple to install but possible downsides include the noise it produces during normal operation and a shorter life span (around 5 to 6 years) compared to a split cooling system. The availability of a suitable adjacent room for ventilation can also be a factor but this could be solved by using air ducts to control where the warm air can be vented. One such wine cellar cooling system that uses this method is the Cellarmate Self-Contained System. Of course, there will be additional costs depending on the circumstances surrounding the installation.

Split systems come in handy when dealing with site difficulties or when installation flexibility is needed. On the other hand his wine cellar cooling unit costs more than self-contained ones and requires an HVAC professional to install it. Ideally, the two units must be at least 50 feet apart, which in most cases means that the condenser unit might have to be located outside the house. This means extra costs for the condenser housing, pipelining sets and power source. Split wine cellar cooling systems are more durable, however, and lasts at least a decade longer than self-contained systems.

Both types of climate control systems are popular and selecting one over the other depends on your wine room’s current condition and, of course, your personal preferences. Just make sure you get everything right and your valued wine collection will turn out right as well.

Red wine is the purest and most loved liquor of the world. Red wine is preferred over other wines because of its various qualities that make it a cherished drink. It is rated very highly for being a health drink by some leading health bulletins. The alcohol content generally ranges between 12 to 15 %. The most common varieties of red wine are shiraz, pinot noir, merlot, zinfandel and cabernet sauvignon.

It is made of dark grapes, it takes intense violet color initially but later it takes red brick color as it matures with time. Its production is a long tedious process but it could be understood in short. This red color comes from the skin of the grapes which consists of anthocyanin pigments which give rich texture, taste, besides colour that attracts all. Red wine is given treatment at the winery during fermentation. The process starts with selected grapes going through stainless steel crushers and later preservatives are added which help on timely fermenting as well as maintain good quality and texture to the drink. Yeast is added and later is goes through the cooling process and then the pressing, the second transformation through microbiological takes place. This is a very important process in wine making. Later it is kept to mature and the process is called racking and ageing. The older the wine is the better quality it would be. Then fining is done to rectify any faults in post production of the wine. Wine is filtered and finally bottling takes place. Bottling is generally done in glass bottles with cork stoppers which give it a classic look.

Consumption of wine depends on the menu being served with it. Red wine is always preferred with heavy red meat and roasted, roasted, cuisine whereas white wine is taken with light snacks like fish and poultry items. Red wine is the most loved liquor or drinks in this universe for various reasons. The foremost reason is that it is good for health if taken in a moderate quantity. It lowers the cholesterol and its consumption prevents heart ailments and some form of cancer as well. As grapes contain antioxidants which prevent oxidative damage to our body and act as a preventive measure in many types of cancer. In a recently published journal is stated that intake of red wine lowers the blood sugar level. In women, if taken in small quantity, it can prevent type 2 diabetes and it lowers sex hormonal levels and protect against breast cancer. Thus we can make out why it is so highly rated by everyone, as it takes care of our heart which is the most important part of our body. Today’s life is full of stress and pressures and we take various measures to release stress including medicines which may have some side effects but your friend red wine can relieve stress and relax your nerves. Well if you catch a cold you do not have to take any specified medicine for it, just a regular glass of red wine will solve your problem. We do not have to think twice as it takes care of our health as a trusted doctor and friend.

Now on a lighter note, it is the most loved drink at dinner time, as it goes well with our cherished hot, spicy red meat. Intake of it with food helps in digestion of heavy food. Ladies are very particular of their looks and slim fit body and take some drastic measures to bring it back to shape. Many go for surgery, medication, yoga, aerobics, but for all this, we need time and guidance or it may backfire too. In such a case lovely ladies prefer to have an enjoyable glass of red wine and get rid of extra fat and toxins is their body.

We always want a true genuine friend in our life and red wine is our true companion and friend which gives us good health as well as gives us makes our dinner and life interesting and enjoyable. So “cheers” and enjoy our life.

Technological advancements in the field of industrial processing have brought dynamic impacts and developments when it comes to productivity and product quality. If before, heating and cooling bulk powder materials using the traditional method is very inefficient and at the same time yields low quality final product. Today, we can find a lot of innovative technology that were expertly engineered to provide efficiency in the major industrial processes like heating and cooling bulk solids such as sugar, fertilizer, chemicals, plastics, dried biosolids, minerals, and many other types of grains, crystals and bulk powders.

The bulk powders heat exchanger technology is one of the worlds leading technologies in cooling and heating bulk solids materials and bulk powders of all types. It was expertly designed with technical superiority compared to other competing technologies we have today. Furthermore, it has many innate advantages that are incomparable and couldn’t be matched with the traditional method of processing bulk solids materials.

Produces Superior Bulk Powder Quality

Unlike with other bulk processing technologies, the bulk powders heat exchanger technology maintains the highest quality while heating and cooling bulk materials by not altering the particle characteristics through out the entire process. This was made possible by making the materials to pass through the bulk powders heat exchanger technology at a slow and controlled rate to avoid any damages to the products and by which also allows the precise prediction and control of the products final temperature.

Energy-efficient Processes

The bulk powder heat exchanger technology saves a lot of energy since it uses up to 90% less energy compared to the traditional method and other competing technologies. This proven efficiency is a result of a proprietary process that does not rely on air, which means users save energy while eliminating emissions. Unlike to the traditional method which rely entirely on air in all it’s processes, this new technology cools and heat bulk products with out the use of air. This means that you save energy and at the same time you eliminates emission and other accompanying problems by having the products contacts with the air.

No Emissions, Dusts, Fines and Odors

With the help of the indirect plate cooling design, air was not used in cooling bulk materials and it has no contacts with the products during the entire process, thus, the risks of bacterial contamination, odor contamination, and product moisture content changes are totally eliminated. Also, emissions, dust, fines and odors are eliminated because air is not used to directly cooling the product.

No Moving Parts and with Compact and Modular Design

The bulk powder heat exchanger technology was designed to process bulk product materials with out any moving parts to provide easy maintenance, reliable operation and years of low cost. In addition, this technology has a vertical configuration making it both modular and compact. Its modular design allows additional heat exchanger plate banks in the future if increased cooling capacity is required. On the other hand, its compact installation makes it easy to integrate in existing plants and is ideal for de-bottlenecking, revamps and capacity increases.

What is the primary purpose of an industrial blower you may well ask. Well, similarly to industrial fans, the various different blowers available on the market ensure the provision of a steady gas or air flow when needed in industrial or mechanical processes, in a whole range of industries from transport to paper and pulp.

Various types of blower exist to serve their many varied applications. Anyone intending to rent or purchase a blower must first describe its use in detail to the salesman to avoid situations where an inappropriate device is bought and installed that could potentially even cause danger.

High Pressure Blowers

The name gives a lot away in this case. These are fans that can handle really heavy industrial applications where pressure is high, meaning the air is hot and heavy, and needs regular movement.

High pressure devices are often employed in grain handling processes, specifically conveying, drying and ventilating.

RPD Blowers

Rotary lobe, positive displacement or “Roots-type” blowers work by pumping a fluid with a pair of meshing lobes. During the process, fluid is trapped in pockets around the lobes and carried from the entrance point to the exhaust.

One of the most common uses of the RPD type is in vehicle engines. Another domain in which it is easy to come across the device is the gas industry. Here, roots blowers are used in reverse to assess the flow of gases in gas meters.

Interestingly, the sophisticated piece of machinery is also used in as narrow a niche as the assembling of civil defense sirens, in which they work to pump air to the chopper.

Submerged Blowers

What makes this type different is that they are fully submerged in the process cooling gas. This ensures contamination never takes place during the cooling process, and makes maintenance easier as, contrary to other types of the device, running seals aren’t used in the design and build.

The submerged version is often employed in the power industry with devices often in strategic use at nuclear power stations. They are often also used by industries that require the implementation and regular use of gas flow calibration loops.

Industrial blowers are a tool without which many industries wouldn’t be fully functionable. They serve an important purpose in most mechanical processes where an air flow is needed. As safety is paramount, this is a must needed investment for anyone looking to launch an industrial operation.

Your body is designed to burn food for energy and produces heat from within. So, don’t forget to eat! If your body is getting cold, it will sacrifice your feet and hands to save its life. Ever wonder why your feet and hands are the first to get cold?! Your body loses heat in 5 ways – radiation, convection, conduction, respiration and evaporation.

1. Radiation: Just as a wood stove radiates heat into a room, your body radiates heat into the air. The more insulation you put around it, the loss of heat is decreased.
2. Convection is moving air. Wind blowing through your sweater or around your jacket is heat lost through convection. Windproof outer layers will help prevent heat loss.
3. Sitting on some cold bleachers at a football game, grabbing a ski pole, or just catching a cold zipper on your neck, are all heat loss by conduction.
4. Evaporation is a very efficient cooling process.

6 Tips for Staying Warm at a Sporting Event:

• Check weather conditions before heading outside. Watch your local weekly weather forecast to make it easy to prepare in advance.
• Dress appropriately. If you are going to be in the extreme cold, wear as many layers of warm clothing as possible. If it’s mildly cold, try to dress in just a few layers and pack an extra coat or sweater in case the temperature drops.
• Be prepared for all conditions. Keep an umbrella, poncho or warm jacket with you. Have an indoor, heated place to go… you don’t want to be stuck outside if the weather conditions become extreme.
• Wear waterproof shoes or boots with a good grip. If your feet are cold and wet, it won’t matter how well the rest of your body is bundled up. You will still be miserable!
• Wear gloves and/or mittens and long thick socks. These protect your hands and feet, which are the hardest places to keep warm blood flowing. Try wearing thinner gloves underneath heavier winter gloves for extra warmth.
• Pack warm food. Sometimes all you need in chilly conditions is hot food or drink. Carry a thermos with hot drinks, soups, or noodles. Warm food and drink will warm you inside and keep your strength up.

Signs and Symptoms of Hypothermia: shivering, shallow breathing, confusion, exhaustion, slurred speech, loss of coordination, weak pulse, unconsciousness (in severe cases)

Treatment of Hypothermia: remove any wet clothing, protect individual against the wind, move to a warm shelter as soon as possible, rewarm the individual with extra clothing, take the person’s temperature if a thermometer is available, offer warm liquids (avoid alcohol or caffeine).

The most efficient tractor engine will utilize approximately 35% of its energy into useful actions of driving, plowing, pulling, transporting and other farm duties. The excess 65% of energy produced will be lost in the form of sound energy, heat energy, radiant energy, vibrations, and friction.

A sufficiently cooled engine, and its counterpart, a sufficiently hot engine, are both necessary for optimum tractor engine performance. An over cooled engine can cause excessive damage to the engine components. Pistons and liners are designed to maintain very specific and minute clearances.

An over cooled engine will have its liners cooler than the hot pistons. The aluminum pistons typically expand faster than the steel based liners, and therefore, there will be scarring between the two surfaces. This damages the pistons, piston rings, and liner surface.

An excessively hot engine will cause all internal components to expand beyond normal tolerances, producing loose components, and burnt tractor engine parts. This is a phenomenon that is referred to as a “shot” engine or “seized” engine by mechanics. The tractor radiator removes excessive heat from the engine. The coolant that is circulating through the engine is allowed to be cooled via the tractor radiator.

The thermostats aids in this cooling process by preventing heated coolant from leaving the engine during the start-up phase when the engine is cold, and allowing coolant to flow through the radiator when the engine temperature is above design temperature limits. The tractor radiator can be manufactured from aluminum or copper or alloys of aluminum or copper. Aluminum or copper is used as both have a high heat capacity, which is the capability to absorb and release a large amount of heat very easily.

The tractor radiator basically has rows of tubes, and onto these tubes are attached thin strips of metal. The coolant is forced through the tubes the water pump. Typically, the coolant flows from the top of the radiator, downwards through the tubes, and back into the engine block. Specially designed radiator hoses perform these high temperature connections between the engine and the radiator.

Onto these rows of metal tubes, are fitted thin strips of identical or similar metal. This effectively increases the surface area of the tubes, allowing the heat form the coolant to travel by conduction to the fins. The fins are typically designed as fins per inch. The 8N Ford tractor radiator and the David Brown radiator model 990 has eight (8) fins per inch, the Allis Chalmers radiator for the D17 has seven (7) fins per inch, the John Deere radiator for model 3020 has ten (10) fins per inch.

The other main component of the cooling system is the radiator cap. This serves to maintain a high pressure in the radiator, thus preventing the coolant from boiling, and it acts like a pressure relieve valve releasing coolant to the reservoir when hot, and pulling coolant into the engine when cold.
