HOT ALONE WON‘T DO THE TRICK!

    HEATING ELEMENTS

    About 5000 to 7000 furnaces for sintering zirconia are produced every year at the moment. The numbers are rising. There 

are two different heating element types that are installed in the dental furnaces on the market to achieve the extremely 

high temperatures, usually in excess of 1400°C (2552°F). By far the largest share of the furnaces on the market is built 

with molybdenum disilicide (MoSi2) heating elements. In some few cases, silicon carbide (SiC) heating elements will be 

used. These two element types differ in their properties in addition to the entirely different basic materials.


    SiC heating elements are usually used up to a 

temperature of 1530°C (2786°F) as recommended by the furnace manufacturer. A firing cycle will take several hours. 

MoSi? heating elements can be used up to a temperature of 

1750°C (3182°F), depending on the quality and furnace type. The maximum application temperature of these heating elements 

therefore is clearly above that of SiC heating elements. Additionally, the surface load, which means the power (W) 

that can be emitted per square centimeter (cm2) is more than twice that of SiC, at above 25 W/cm2. This permits much faster 

heating-up rates, to much higher application temperatures. Heating to 1550°C (2822°F) in less than 15 minutes is 

possible.

    MolyCom?-Hyper 1800 (MoSi2) heating elements that have been used on the international dental market since 2005 have 

turned out to be much longer-lived than SiC elements in continuous tests and according to the experience of various furnace 

manufacturers. SiC elements usually need to be replaced after just a few hundred cycles due to the strong change of 

resistance, which corresponds to a service life of approx. 1-2 years at common use. MolyCom?-Hyper 1800 elements in 

contrast have been operated for more than 2500 cycles without any failure or need for exchange. Exchange of the defective 

element is usually sufficient in MoSi2 heating elements. In contrast to this, all parts of the SiC elements must be 

exchanged in one due to the strongly impaired resistance.


    If we additionally compare the chemical analysis of the heating elements, the standard heating elements show a much 

higher degree of contamination, in particular by iron oxide. No contamination could be measured at use of the MolyCom?-

Hyper 1800 elements up to a temperature of 1630°C (2966°F). No contamination was measured for MolyCom?-Hyper 1800 Super 

Clean elements up to 1680°C (3056°F).


    Additionally, a contaminated zirconia sample on the surface was analyzed with a secondary ion mass spectrometry 

(SIMS). As the analysis shows, increased contents of iron oxide could be documented in the sample up to a depth of 0.15 

μm. While the degree of contamination is very low, it has a considerable visual effect. The vapor pressures of many 

different oxides at the surface temperatures of the MoSi2 heating elements in the furnace were additionally calculated 

with Fact Sage. 

    Among the ceramic materials, silicon nitride ceramics possess 

good overall performance (e.g., high hardness, high strength, low density, low thermal conductivity, low chemical activity, 

and high wear resistance), which promotes these applied as rolling bearing, machine tools, sliding bearing in water pumps.

    Aluminum titanate has outstanding properties that make it 

ideally suited for applications involving molten aluminum, including complete resistance to wetting by aluminum alloys, 

total gas impermeability, and a very low thermal expansion coefficient. This material offers a longer service life 

and higher reliability when compared to cast iron, calcium silicate or fused silica components. All riser/stalk 

tubes are 100% leak-down tested, and parts are available with gasketing and ceramic foam filters to provide complete 

assemblies.


    Alumina ceramic is an industrial ceramic that has high 

hardness, is long wearing, and can only be formed by diamond grinding. It is manufactured from bauxite and can be shaped 

using injection molding, die pressing, isostatic pressing, slip casting, and extrusion.


    Reaction bonded silicon carbide has excellent 

wear, impact, and chemical resistance. The strength of RBSC is almost 50% greater than that of most nitride bonded silicon 

carbides. It can be formed into a variety of shapes, including cone and sleeve shapes, as well as more complex engineered 

pieces designed for equipment involved in the processing of raw materials.


    Ceramic fiber paper is a must-have for those who work in the 

manufacturing industry. It’s a type of the high-temperature insulated paper that’s integral to many manufacturing 

functions. For one thing, ceramic fiber paper has a huge variety of applications — whether it’s protecting gaskets (like 

rope gaskets) from high temperatures or providing insulation — and there’s a range of grades and thermal conductivity, 

depending on what’s needed. If you’re looking to purchase ceramic fiber paper, we’re your best bet — we’ll 

discuss some of the benefits and applications that you might not have expected out of this material and what you should 

expect when ordering and handling it. 

    One of the major benefits of using ceramic fiber paper is that it has a low thermal conductivity and doesn’t store 

much heat. It’s also thermal shock resistant and is resistant to most chemicals, which means it has a low corrosion rate. 

It’s great if you’re looking to die-cut or use automatic stamping and has high dielectric strength as well. 


    Another benefit to this type of paper is that it’s lightweight and uniform in its structure, which makes it a great 

type of insulation. It’s also flexible and fire-resistant! 

The Difference Between Network and Server Racks

    Before purchasing a server cabinet or server rack it is import ant to understand the difference between the 

different products that are available. This will ensure that you purchase exactly what you need.


    Server Cabinets

    Server Rack Cabinets such as the 42u Server Cabinet are generally nineteen inches wide by industry standards. This 

products is mostly used to install servers, UPS ES, monitors or similar equipment. Server rack cabinets, for the most part, 

are twenty-four inches in width, and thirty six inches deep. Some companies offer other measurement options to meet 

customers’ needs, however. [url=http://www.nbjingheng.com/network-cabinet/floor-standing-network-server-rack-

cabinet/]Floor standing network server rack cabinet[/url]s usually have a perforated front and rear. This feature offers 

ventilation for the equipment being housed. This is crucial to providing a safe environment for this type of equipment 

which generates a good deal of heat.

    Network Cabinets


    Network cabinets or Network Racks are often confused with server 

cabinets. However, there is a difference. Network cabinets are generally used for the storage of routers, 

patch panels, switches and a wide variety of networking equipment as well 

as networking accessories. In most cases a network cabinet will be far shallower than a server rack cabinet, generally 

measuring in at less than thirty one inches deep. Outdoor network 

cabinets will sometimes have glass or a strong plastic front door. Network cabinets also generally do not have 

perforated enclosures. The type of equipment generally housed in network cabinets does not generate the same amount of heat 

as that housed inside a server rack.


    Because one product can not fulfill the needs of all office equipment storage, it may become necessary to do a thorough 

evaluation of the type of equipment being used, or that will be used, in order to make the most informed purchasing 

decision. In many cases, office spaces will require the use of both a server rack and a networking cabinet in order to 

house the various equipment that will be used there.
It is important to note, that improperly housing heat generating equipment is dangerous. This could cause damage to your 

equipment, or worse could become a fire hazard due to the temperatures which some servers can generate. Good rack dealers 

will help you decide which product is best for you.


    Monitoring can be done either at the incomer of the PDU sockets in 

terms of the total power being drawn from the whole PDU, or it can be focused on an individual device’s demands from the 

socket. The latter provides a greater granularity for analysis but not all meters have the same accuracy, it may range from 

one to five percent, so it is worth investigating into the technical specifications.


    PDU electronics also consume power at levels which can be significant, especially in a large scale data centre, given 

that it can range from as little as six to 60 watts. If intelligent PDUs are installed in a 200 rack data centre with dual 

PDUs in the rack then their power consumption could be as little as 2.4kW or as much as 24kW.


    The switching function allows users to remotely shutdown individual sockets and to ‘hard boot’ any device that is 

connected to it. It is worth checking which type of switch device (or relay) is within the PDU construction, either 

monostable or bi-stable. The monostable needs a permanent supply of power to change state and stay there. Bringing it back 

means removing the power. 


    The bi-stable needs to be pulsed with electricity to change state and pulsed again to come back. Bi-stable therefore 

uses less power than monostable, which can again be significant in terms of the aggregate consumption from a lot of 

sockets.

Everything you wanted to know about UV Lamps

    The use of UV light as a curing technology has been around for a long time. In the last few years it has become more 

popular since the technology on the lamps and the materials side has greatly improved. Applications are now on sheetfed, 

web and wide format inkjet equipment. The major advantages of UV inks are:



    1)    Press sheets are dry when they come off the press


    2)    Higher throughput speed than Infra-Red drying


    3)    No Volatile Organic Compounds released in the air


    4)    Resist smudging and abrasion


    5)    UV Coatings have a “wet look”


    6)    Do not have solvents to penetrate uncoated stocks


    Most printers buy UV power supply systems that may be supplied 

by the manufacturer of the equipment but made by someone else. Understanding how UV lamps work can improve their 

performance and save you money.


    There are series power supply for 

different applications. Low-pressure UV lamps may be used for disinfecting purposes, curing nails and dental fillings, or 

water purification. The type of lamp used in printing applications is usually a medium pressure, linear (straight tubes), 

mercury vapor arc lamp. Medium pressure UV lamps cure inks and coatings instantly. It is a photochemical, not a heat 

process. It allows the equipment to run at very high speeds for extended periods.


    General use light bulbs have a filament. The electricity causes the filament to glow, producing light. Medium pressure 

UV lamps do not have a filament. They utilize a high voltage charge to ionize a mercury/gas mixture in the lamp creating a 

plasma that emits UV light. This system requires a high voltage/amperage power supply (typically a magnetic ballast 

transformer with a high voltage capacitor bank). The ballast is wired in series with the lamp and performs two functions. 

Initially, the ballast provides a high voltage charge to ‘strike’ or ‘ionize’ the mercury. Then, once the mercury is 

ionized, the ballast reduces the voltage and amperage required to keep the mercury ionized and emit a stable stream of UV 

light.


    These lamps generate a specific wavelength to cure the inks or coatings. Currently, most of these lamps operate at 300 

to 600 watts per inch with some newer systems using lamps that generate up to 1000 watts per inch. So a 30 inch UV bulb may 

be capable of an output of 30,000 watts. They also operate at very high temperatures (850 to 950 Celsius or 1550 to 1750 

Fahrenheit).


    This type of UV lamp is made from Quartz. A general glass product would not be able to withstand the high temperatures. 

An inert gas (usually argon) is pumped into the quartz sleeve and then mercury is added to achieve the proper electrical 

specification. Iron and gallium are occasionally added to achieve special wavelengths. The tubes are sealed and the correct 

electrical end-fittings are added to complete the lamp.


    These lamps need a powerful cooling system to offset the high operating heat. They are usually air or air and water 

cooled. They also use reflectors to maximize the ultraviolet light delivered to the substrate. There must be an even flow 

of air or water across the lamp for proper curing. If lamps run too cool they may not cure the ink or coating. Some systems 

use outside air for cooling. As the seasons change, depending on your geographic location, you may need to adjust your fan 

speed or increase/decrease water temperature to maintain proper cooling.


    Contamination is another problem that can affect lamp performance. Due to the high heat air contaminants such as spray 

powder from other presses or dust particles can bake on the lamps creating a haze. This decreases the performance of the 

lamps. Ideally, even after extended use the quartz should be completely clear.


    The xenon searchlight is delivered with a built-in xenon power 

supply, excluding large and heavy external power supply’s. This design enables easy installation (no external power 

supply TA values or IP-ratings to be considered) and significant cost savings, by reducing engineering and eliminating 

these cables and connections:


    - Cable between power source and external power supply
- Cable between power supply and searchlight
- Remote signal cable between searchlight and power supply


    UV LED systems have a bright future in industrial and life 

science applications even given the fact that humans can’t see the light. In particular, LEDs in the UV-C band (generally 

100–280 nm) promise to revolutionize sterilization and disinfection and could bring safe water to people around the globe 

and safer conditions to our medical facilities (Fig. 1). LEDs Magazine, in fact, covered a [url=https://www.hpe-

uvpower.com/uv-led-system/uv-led-curing-with-4in1/]UV LED Curing with 4in1[/url] designed for such an 

application earlier this year. Still, we hear that such applications need LEDs with higher performance and longer 

lifetimes to truly penetrate the market. But UV product developers need to rethink LED lifetime as another variable in the 

engineering process.

WPC Flooring, SPC Flooring and LVT Flooring: What Differences, Similarities and Benefits?

    If you own a modern home or have plans to own one in the future, you must have heard of vinyl floorings. These 

affordable and stylish flooring options are increasingly becoming the choice of many homeowners and commercial property 

owners who want to give their living and working spaces a fresh look. 


    There are three main types of vinyl flooring - WPC flooring, LVT flooring

and SPC flooring. In terms of market entry, traditional versions of 

Luxury Vinyl Tile flooring have been in the market for many years. With time, changes in buyer preferences led to the 

development of advanced flooring solutions that saw rigid core vinyl such as WPC and SPC flooring hit the market.


    Even so, each flooring type comes with its own set of benefits and drawbacks that you need to consider before settling 

for one. Though different, the three flooring types share several similarities.


    In this article, we explore the benefits, differences and similarities that SPC Vinyl flooring, LVT and WPC floorings 

have. 


    Before we delve into this, let's first define each of these vinyl floorings:


    LVT Flooring


    Luxury Vinyl Tile is an updated and innovative version of vinyl flooring that is today a top contender when it comes to 

floor installations in commercial and living spaces. Designed with a real wood, stone or ceramic look, 

carpet grain LVT flooring is not just 

affordable, it is also durable, waterproof and resistant to scratches. 


    SPC Flooring


    Stone Plastic Composite (SPC flooring), also referred to as Rigid Vinyl Plank, is an upgrade of LVT. SPC vinyl 

flooring comes with multiple layers and backing options that make it ideal for homes. Some key aspects that make it 

stand out include low noise levels, no warping, eco-friendliness and insulation against sound and heat. 


    WPC Flooring


    Wood Plastic Composite (WPC) derives its name from the wood-like material used to make it. These materials include a 

foaming agent known as polyvinyl chloride, plasticisers, wood flour and calcium carbonate. 


    Benefits of LVT, WPC and SPC Flooring


    There are numerous benefits that home and commercial property owners derive from using vinyl floorings. These include:


    1.Wear Resistance


    All three vinyl floorings - WPC, SPC and Luxury Plank Vinyl have a high resistance to wear and tear. This means if you 

choose to install any of them in your home or commercial entity, you can use them for a long time without seeing signs of 

wear and tear on them. 


    2.Do Not Fade Fast


    While WPC, LVT and SPC floorings will eventually fade, they do not do so fast. As a matter of fact, these flooring 

score moderately when it comes to fade resistance. This is because they have a UV coating treatment that keeps their color 

from fading fast. This means that once installed, you don't have to worry about your floor losing its shine and color 

in a few years. With proper maintenance, you can enjoy a great floor appearance for a considerably long time. 


    3. 100% waterfroof


    When constructing a home or a commercial building, you'll need to put waterproof flooring in rooms. The 

high moisture resistance feature in LVT, SPC and WPC floor makes them an obvious choice for such spaces. SPC and WPC floor 

have a core that is completely waterproof. These vinyl click floor can be installed in places like kitchens, bathrooms, 

basements and laundry rooms where hardwood or moisture sensitive floor types are not recommended. 


    4.Easy to Install


    Installing WPC, SPC or LVT floor is pretty easy and DIY installation is possible. Since the vinyl planks are easy to 

attach and lock, they can be installed on any existing floor or subfloor without using glues. 


    However, there are places that each floor type works well. For instance, due to their rigid core, SPC vinyl plank 

flooring are suitable for commercial buildings. On the other hand, WPC floor are most suitable for residential spaces due 

to their ability to hide floor imperfections. LVT vinyl flooring work well in leveling uneven surfaces while WPC can cover 

crafts on concrete or wooden floor. 


    5.Design Options 


    If you decide to fix a WPC, LVT or SPC floor in your commercial or living space, you'll be spoilt for design 

choices. All the three floor types are available in numerous designs. They are available in just about any pattern and 

color.


    Making them in different designs is easy - all manufacturers have to do is to print patterns on the vinyl layer. Most 

designs resemble other floor types. For instance, you'll find SPC and WPC floor that have designs similar to stone, 

tile and hardwood flooring.


    6.Easy to Maintain 


    All three floor types are pretty easy to clean and maintain. To keep them looking great, all that home or commercial 

space users have to do is sweep them regularly and clean them occasionally. 


    Key Differences and Similarities Between LVT, WPC and SPC Flooring


    While they have similarities, WPC, LTV and SPC floorings also have several differences. These include: 


    1.Manufacturing Materials


    These three vinyl floorings differ in the composition of the materials that are used to make them. SPC flooring is made 

from polyvinyl chloride, limestone powder and stabilizers. While WPC floorings also contain polyvinyl chloride, the other 

materials differ from those used in SPC flooring. The limestone powder and stabilizers are replaced by plasticisers, wood 

flour and calcium carbonate in WPC flooring. 


    2.Structural Design


    LVT, WPC and SPC are all hybrid flooring. This means they are designed with several layers. However, the layers vary in 

type from one flooring type to another. For instance,

wood grain SPC flooring has a core layer that is made of PVC powder, a stabilizer and calcium powder. On the other 

hand, LVT Vinyl Flooring have a decor and a wear layer. For the WPC floor, the core area comprises a foaming layer and an 

LVT layer that has PVC powder, calcium powder and a plasticizer.


    The other major structural difference between WPC and LVT or SPC flooring is in the way they have been 

constructed. LVT Plank flooring have a PVC core while SPC vinyl plank flooring have a rigid core. However, both of 

them can move and even flex with ease. This is not the case with WPC floorings. Due to the wood-plastic composite material 

that is used to fix their core, these floorings are more stable and more solid compared to LVT and SPC vinyl flooring.


    3.UV Top Coating


    The top layer in the all three vinyl floors -SPC, LVT and WPC - are the same. Each of these floor has a UV coating that 

helps in maintaining their lush appearance by preventing color fading. 


    4.Thickness of Floor Planks


    Generally, the thickness of the three flooring planks ranges between between 3.2mm and 8mm. However, WPC floor planks 

are much thicker compared to LVT and SPC floorings. With a thickness that ranges between 3.2 mm and 7mm, SPC Vinyl flooring 

are not as thick as LVT plank flooring that measure 4mm and WPC flooring that have a minimum thickness of 5mm.  


    5.Firmness of Vinyl Planks


    When it comes to firmness and cushioning, WPC floor carry the day. The sturdiness of floor vinyl is largely determined 

by the material that is used to develop its core. Since WPC vinyls have a thicker core than 

stone grain SPC flooring or 

stone grain LVT flooring, it is more stable 

and has a cushioned feel when you walk on it. SPC floor also have a relatively high level of sturdiness, which causes the 

floor to feel softer. The sturdiness also protects SPC flooring against dents and wear.


    6.Floor Plank Insulation


    Insulation capabilities vary from one floor type to the other. If you prioritize sound insulation, go for a floor plank 

that has a thicker core like WPC. Because they do not have thick cores, LVT and SPC flooring perform poorly when it comes 

to absorbing noise than WPC floor. The thickness absorbs impact sounds, which reduces the noise that the floors produce as 

you walk on them. 


    7.Durability of Vinyl Planks


    While all three floor types are designed to last for an extended period of time, their durability varies from one floor 

type to another. In most instances, durability of vinyl floor is determined by how thick the top wear layer is. 


    Even so, SPC floor is not as thick as WPC flooring. However, the former are denser than WPC floor - an aspect that 

makes them more resistant to damage arising from heavy weight or impacts. Since they do not tear or wear easily, SPC floor 

become ideal for areas that are prone to high traffic.


    8.Cost of Vinyl Planks


    Vinyl planks are generally not as expensive as other forms of flooring. However, out of WPC, SPC and LVT flooring, SPC 

flooring tends to be the most affordable. 


    9.Resistance to High Temperature


    While LVT, SPC and WPC flooring can be installed in rooms that have high moisture exposure, not all of them can 

withstand high temperatures. WPC and LVT floor do not work well in spaces that experience high temperature changes. If you 

have such spaces, carpet grain SPC flooring will 

perform much better compared to the other two. This is because SPC floor have a denser core that causes them to resist 

contractions and expansions compared to WPC floors. 


    10.Environmental Friendliness


    Eco-friendliness of vinyl floors depends on the materials that are used to make them. Since WPC and 

Wood grain LVT flooring contain plasticiser, a 

material that is not eco-friendly, they are not considered environmental friendly. SPC flooring do not contain artificial 

materials like glue and plasticiser. These vinyl floors are therefore considered eco-friendly - which makes them a great 

choice for pets and kids.

Active Cashmere | Luxury Innovation and Modern Design

    Consumers will now be able to enjoy all their favorite qualities of cashmere without any of the drawbacks of this 

typically delicate fabric. Active Cashmere is the first performance-based 

luxury cashmere that is water repellent and durable among other key characteristics that reinvent the way cashmere is worn.


    Active Cashmere perfectly blends quality and function by utilizing an innovative fiber treatment process that enhances 

the cashmere’s natural qualities. Active Cashmere garments are breathable and have a comfortable and soft hand feel. The 

proprietary process allows the cashmere to be machine washable with no shrinkage, retaining the garment’s initial shape 

and form, and significantly reducing any chance of pilling, felting, fuzzing, or discoloration on the cashmere. At the same 

time, the machine washable series is water-

resistant: water repels off the garment’s surface eliminating any absorption and wetness that typically would occur with 

cashmere and maintaining complete dryness on the inside of the garment. Any water on the cashmere is limited to the surface 

and dries within minutes, whereas traditional cashmere can stay wet for up to an hour causing the immediate odor.

     

    The debut Active Cashmere collection launches direct-to-consumer this Fall 2020 via their website and in select 

retailers for Winter 2020 / 21. The collection ranges between lounge, leisure, and active pieces that are versatile, in 

addition to core items that serve as all-purpose wardrobe staples. The modern aesthetic and refined design approach 

combined with superior functionality is set to transform the perception of cashmere in today’s marketplace. Whether worn 

in an outdoor social setting, for recreational activities, during or post-workout or simply as day-to-day wear, 

mixed color series provides a solution to our 

fluid new-age lifestyle.


    The pieces range from a sweatshirt-inspired sweater (a new take on a classic crew) to a cropped sweater and sweatpant 

set, to short sleeve tops and shorts, to midweight and lightweight long sleeves. The majority of the collection utilizes 

WHOLEGARMENT knit techniques that make the seamless 

wholegarment series proving both minimalism and comfort. The craftsmanship on the material and knitting 

construction provides for quality, breathable and long-lasting pieces that can serve our year-round cashmere needs for 

years to come.

    Active Cashmere is founded by DanRoy, a family-owned company deeply rooted in Scottish cashmere heritage with over 60 

years of experience in the industry. Together with Todd & Duncan, the world’s largest and finest Scottish cashmere mill, 

DanRoy is the first company worldwide to infuse this treatment and proprietary process into both the cashmere yarn and 

knitting process, while maintaining the highest quality and sustainability standards. 


    Unlike other chemical processes, the heavy cashmeres 

series technology lasts for over the life of the garment and the treatments used are non-toxic, non-hazardous, hypo-

allergic, and have no ancillary impact on the environment. As industry veterans, DanRoy is a proud member of CCMI, the 

cashmere organization that sets the global standard for quality. They utilize a fully sustainable supply and 

production chain, sourcing the highest grade and ethically-sourced raw material, working with manufacturers who recycle 

their water and reduce water usage, and eliminating fabric waste through WHOLEGARMENT knitting techniques.

    Wool fabrics can be classified by their production technology — the worsted and woolen ones. 

Woolen cashmere series are spun from short fibers, 

while worsted wool is made from long and fine ones. Compared to woolens, worsted wool fabrics are brushed in two 

directions with special brushes. Wool yarn differs in quality: it is bulky for woolen fabrics and smooth for worsteds.

    Worsted cashmere series are lighter, smoother 

and more durable, but provide less warmth. However, they are better at keeping off rain. Worsted wool requires more 

processing (remember, it is made of long staple fibers only), it tends to be more pricey compared to woolens. The most 

common uses for worsted fabrics are suits and tailored clothes.

now, five times a week, and we are impressed. Not only is it quite compact to store, but it also has a range of workout 

programmes so you can mix up your workout routine. That and it has four user settings so more than one person can use the 

bike in your home, while there are 32 resistance levels to offer a sweaty workout.


    When in use
On initial setup, you can set a user programme from one to four and input your gender, age, weight and height so it 

knows who is using the machine. We've used this spin bike in 

manual mode and tried every one of the programmes. We prefer the programmes as they give structure to our workout and keep 

us motivated, and it's even better than you can tailor them to suit your needs. By this, we mean that you can input a 

time or distance, or the number of calories you'd like to burn, and the programme will run until you reach your goal. 

You can also set the 'load' which is the starting resistance, based on your fitness level or how hard you want to 

push yourself. This bike automatically ups the resistance for you, though you can change it at any time by turning the flat 

button on the console. After your workout is finished, the machine will beep to let you know. From here you can either 

finish or head to manual mode to cool down.


    Practising yoga at home? You can't go wrong with the Yoga items

: they feature alignment markers so that you know where your hands and feet should be while posing. It's great 

for those who usually attend a yoga class and rely on help from their instructor when going from one position to another.

    An easy (read: fun) way to get your heart rate up, this one is our pick of the best fitness trampolines you can 

buy. Fitness trampolines are smaller versions of your classic outdoor trampoline and are otherwise known as a 

trampette.


    When in use


    This piece of fitness equipment has been popular for quite a while now, and it's easy to see why: jumping on a 

fitness trampoline is considered moderate to vigorous-

intensity exercise. This device is easy to assemble as you only need to attach the non-slip feet on, it has a solid 

and stable construction that's ideal for aerobic use AND it's super affordable. Just start bouncing!


    If it's a running machine you are after, then the treadmill is our top recommendation. Not only does it feature a 

cushioned deck for protecting your joints when jogging, sprinting or running, but it features a range of pre-set programmes 

and adjustable incline for simulating uphill running.


    When in use
Boasting easy to use buttons and a seven-inch display, this treadmill

allows you to adjust speed and incline settings safely, without the need to look down. You can also use this machine 

for heart rate training, as well as tracking time, pulse, speed, incline, distance and calories burnt. There are 43 

workout programs at different intensities for you to enjoy, and a 15 per cent incline (at 15 levels) to really make you 

work up a sweat. Use the free tablet holder for watching Netflix while working out, or, Kinomap allows you to run stunning 

routes from all over the world, inside your home.

    If you don't have enough room in your home for a home gym (same) then consider a 

pull up bar. Use this sturdy bar for pull ups, chin ups and 

push ups, and then pop it away underneath your bed or sofa after use. 


    If you want to have flat and lean abs, then the sit up bench is 

just best for you. Aside from this, it provides a lot of benefits. Strengthens your core - keep in mind that your core 

is the area of your hip flexors, abs and lower back. By means of having a stronger core, you will be able to move and lift 

better. And the sit up exercise bench can especially help you strengthen your core.

Covid-19: Disinfection Robots Are Being Deployed

    Robots using different technologies are being deployed on the frontline in the fight against Covid-19. Among these 

robots, disinfection robots are of particular interest. A 

division of Siemens has produced one such robot in just a week.

    Models using hydrogen peroxide vapor (HPV) and ultraviolet (UV) light are moving through hospitals, health centers, 

government buildings, and public centers across the globe in a bid to disinfect surfaces. The use of automated 

air disinfection machines not only reduces human 

exposure to the virus but is also proving to be more rigorous and effective in decontaminating spaces. Some of the 

robots incorporate bulbs that emit concentrated ultraviolet-C (UVC) light.

    Danish company UVD Robots is manufacturing robots that are able to disinfect patients and operating rooms in 

hospitals thanks to powerful short-wavelength UVC lights that emit enough energy to eradicate the DNA or RNA of any 

microorganisms that are exposed to them. US-based Xenex also counts on UVC light to annihilate the virus on 

“high touch” hard surfaces, such as bed rails, trays and call buttons. Melinda Hart, media relations director 

at Xenex, explained that the radiation damages the structure of genetic material and prevents particles from 

making more copies of themselves:

        “UV light has been used in this area for a long time and there are dozens of technologies out there that use 

mercury bulbs to emit a continuous stream of UV light. What makes our LightStrike Germ-Zapping Robots so different is that 

they use a pulsing Xenon lamp not a mercury bulb.This emits intense flashes of germicidal light, which are able to 

deactivate a pathogen very quickly so it can’t reproduce and mutate.”

    The LightStrike robots, which are now being used in Europe, Asia, and the US, can disinfect a hospital room in 20 

minutes and have been proven to reduce the spread of bacterium and bugs such as MRSA (Methicillin-resistant Staphylococcus 

aureus) and C. diff (Clostridium difficile). 

[blockquote]
    
        “Covid-19 is not yet available in a commercial lab for testing but we have tested against Middle Eastern 

Respiratory Syndrome (MERS) and other surrogate viruses. Our robots were able to deactivate those quickly, so we are quite 

confident that they are destroying Covid-19.”

    An Intelligent Solution

    At Siemens Corporate Technology China, the Advanced Manufacturing Automation (AMA), which has a focus on special 

and industrial robots, unmanned vehicles and intelligent equipment for robotic applications, also moved quickly to help 

tackle the spread of the virus. The laboratory produced an intelligent disinfectant robot in just one week, explained 

Yu Qi, head of its research group. Its model, which is powered by a lithium battery, distributes a mist to neutralize 

Covid-19 and can disinfect 20,000 to 36,000 square meters in one hour.

    For Yu Qi,  many disinfection machines available on 

the market combine a petrol-driven mistorizer gun with an electric chassis. However, on-site refueling is neither 

clean nor convenient, so the team decided to develop purely electric robots.

[blockquote]
    
        “An omni-directional camera platform on the top transmits videos and information in real time, enabling the 

operator to remotely locate affected areas and control the sterilizing. Considering the multi-scene adaptation, the 

disinfectant robot project designed a caterpillar chassis which has the ability of 35-degree slope climbing and 160mm-

height-of-obstacle crossing. It means the robot can be widely used in hospitals, bus stations, metro stations, 

manufacturing factories and canteens etc.”

    Disinfecting PPE

    Melinda Hart, from Xenex, explained robots are now also being used in pods to disinfect mobile and high-touch 

complex equipment, such as ventilators and scanners. Equipment can be wheeled in and the LightStrike will be effective 

on anything within the pod.

    “Our robots and pods are being used to disinfect masks where there are shortages of personal protective equipment 

(PPE). They can disinfect hundreds of masks in one day, which can make a real difference.”

    YOUR HOME IS now your workplace, playground, meditation studio, dine-in restaurant, neighborhood 

bar, refuge, and movie theater. The point being, you're spending a lot of time in it. You may as well prevent the 

air inside from making you sick. Indoor air is dirty. Particulate matter, volatile organic compounds, and vaporous 

chemicals seep in through our ventilation systems and the weatherstripping around windows. Indoor plastics, furniture, 

paint, and also flooring off-gas noxious fumes. An air sterilizer 

won't do much good if you're not vacuuming regularly and changing the filters in your home's HVAC 

system, but if you live where there's a lot of pollution or wildfires, it could help a lot.

    Whether it is the eradication of biofilm or treating wounds in locations not conducive to sharp debridement, ultrasonic 

debridement can be a key tool for promoting improved wound healing.The surgical debridement of nonviable tissue is 

essential in the wound care process. While sharp debridement with or without pulse lavage is the most common method, the 

use of an ultrasonic wound debridement machine

is a more recent option that one should consider. Physicians originally developed ultrasonic debridement for 

dentistry in the 1950s and later adapted it for debulking soft tissue and dissecting bone.

    Forget about the hassle of ice packs, cold therapy machine

s are the easiest, most effective way to apply for continuous relief from joint pain and swelling and inflammation. 

Whether you’re recovering from surgery, recovering from a workout, or simply seeking relief from a painful medical 

condition, a cold therapy machine can help speed your recovery and ease the pain.

    Studies in the early 1970s suggested that wrapped sterilization 

trays remained sterile for varying periods depending on the type of material used to wrap the trays. Microorganisms 

were found to penetrate single-wrap muslin as early as three days, and double-wrap muslin and single-wrap two-way crepe 

paper in 21 to 28 days when stored on open shelves. Based on these studies, the Joint Commission on Accreditation of 

Hospitals (now Joint Commission of Healthcare Organizations) required that hospitals provide an expiration date on wrapped 

surgical trays, indicating a time when the trays would no longer be considered sterile. In a 1984 article, Mayworm 

criticized the scientific basis for dating sterile surgical trays. He noted that "time doesn't contaminate 

products, events do." He then listed the following factors, which contribute to the contamination of product: 

bioburden (contamination in the environment), air movement, traffic, location, temperature, humidity, and the barrier 

properties of the wrap material. He stressed that when the proper wrap materials along with appropriate sterilization 

techniques were used, surgical trays should remain sterile unless damaged. Subsequent studies demonstrated that the sterile 

integrity of surgical packs was maintained for at least one year and no trend was found toward increased probability of 

contamination over time. In this latter study, no differences were observed among the wrapping materials studied (i.e., 

two-ply reusable, nonbarrier wovens, both new and previously used; disposable, barrier nonwovens; and paper/plastic peel 

pouches). These studies were conducted under ideal circumstances. Sterility may be more difficult to maintain under actual 

use conditions where movement and storage conditions may damage wrap materials.
