Marble vs granite: in this article we will try to clarify the difference between marble and granite, two wonderful rocks. Both are natural sandstones extensively used in interior and exterior design, for modern and rustic furniture. They are characterized by high resistance, timeless beauty and versatility: but what is the difference between marble and granite? In order to analyze the granite marble difference, we must focus on three main aspects: geological, chemical and aesthetic difference.




Since granite is rich of silicates, it is tougher and more resistant especially to resistant to acid substances, scratches, wear and atmospheric agents. This is the main reason why granite is preferred in outdoors applications or in places where heavy foot traffic is expected. Yet, the processing of granite is not easy at all as it is cut and broken with difficulty and, in fact, its cost is on average higher than that of marble.

The main difference between marble and granite probably lies in the aesthetic properties. On the one hand, granite is characterized by a particularly recognizable “speckled” effect and its color is determined by the variation in the percentage of minerals (such as quartz, mica, feldspar, amphibole, etc.) contained in the stone. Marble is unanimously considered more fascinating due to its irregular veins and varieties of colors based on its impurities.


Another difference between marble and granite in design concerns the production of pieces of furniture. Due to the difficult workability and the change in aesthetic standards, granite has been used less for furniture design compare to the 70s and the 80s when it was more popular. Today, however, it seems that a trend inversion is taking place. This is true also thanks to new types of finish available: with a matte finish, matt imported granite can beautifully adapt to more contemporary furnishing compared to the typical glossy finish granite. In conclusion, to the question granite vs marble dining table, the Customer’s response may not be so obvious nowadays.



Another quite common dispute in interior design is surely the choice between marble vs granite countertops. We do not believe that there is a better choice between the two materials but, beyond their geological and chemical difference, there are a number of aspects to consider when it comes to marble vs granite countertops. For what concerns durability, both materials are high resistant stones. However, granite is harder than Chinese marble and less porous so it is more difficult to get it cut, ruined by heat and stained. Moreover, both materials need regular sealing but marble surfaces require more careful cleaning compared to granite, this to avoid damaging the porous stone. Finally, talking of appearance, marble is unanimously recognized as the most versatile between the two. Marble veining is generally considered more elegant by designers and the infinite varieties offered by marble make this material more easily combined with styles that are also very different from each other, from rustic and traditional to luxurious and hyper-modern spaces.

Tapping into touch screens
Most of us are pretty familiar with touch screens. We use this technology daily with our phones, computers, at the ATM, or at the grocery store checkout. Even restaurants have implemented touch display ordering and payment right at the table. Even though we’re constantly tapping and swiping our screens all day long, few of us can actually answer the question: how do touch screens work?


With the first touch screen debuting in 1965, we’ve seen incredible advancements in touch screen technology and computing technology in general. If we told E.A. Johnson that over 2 billion people currently carry touch screens in their pockets every day, he probably wouldn’t have believed us. But that same technology he developed for the Royal Radar Establishment helped shape the future of the modern touch screen technology that we use daily [1].
There are many iterations of touch screen technology including infrared and surface acoustic wave (SAW), but there are two that most of us are familiar with. The most common smart touch board screens we interact with today are capacitive and resistive touch screens. Let’s get to know how these technologies work, and where you’ll see each.

Capacitive touch screens
Capacitive touch screen technology is the style we interact with most. This is the kind of display we see in our smartphones, laptops, and tablet screens, and digital signage.
Capacitive screens are made up of multiple layers of glass and plastic, coated with a conductor material like indium tin oxide or copper. This conductive material responds when contacted by another electrical conductor, like your bare finger. When you touch your screen, an electric circuit is completed at the point where your finger makes contact, changing the electrical charge at this location. Your device registers this information as a “touch event.”
Once a touch event has been registered, the screen’s receptors signal this event to the operating system, prompting a response from your device. This is the application’s interface that you experience.

Capacitive touch screens generally have a brighter, clearer appearance and are much more sensitive than resistive touch smart board screens. We tend to see capacitive touch screens in more modern technologies like smartphones and tablets. They give us the ability to experience high-quality imagery that imitates reality.


Each screen has strengths and weaknesses that make it a better choice for certain applications. Capacitive screens with portable monitor offer more flexibility in functionality as resistive screens lack the ability to register multiple touch points at the same time.from the operating system.

This means that other objects with the same charge as your bare finger could complete the same request when using your phone, tablet, or interactive touch screen laptop. This is why touch screens respond to styluses, special gloves, and the occasional pocket-dial.


The good news is that as technology in touch screens has advanced, so have their durability. Touch TV Screen protectors aren’t as necessary now as they were when consumers were first introduced to touch screen products. Many of us are still scarred by the first time we shattered the glass display on our shiny new device. Contrary to over-protective techies, you don’t need to worry so much about the safety of your screen thanks to developments in materials.

Today, as I work with wire harnesses that are built for electronic devices, I am reminded of those days coaching the kids on how to put the play together. First, the wire harness specifications are drawn up in the same way we would diagram the play. Then, the harness is meticulously laid out, just as we demonstrated to the kids how to execute the play. There’s a lot more to the process of course, and thankfully, the wire harnesses usually don’t talk back to us. Here are more details of the PCB wiring harness manufacturing process that your contract manufacturer should go through when building your assemblies.

Input: What Your CM Needs for the Wire Harness Manufacturing Process

Contract manufacturers often build both flat ribbon cable assemblies and wire harnesses. To distinguish between the two, a multicore cable assembly is an external connection to devices and will have different environmental considerations, such as their thickness, insulation type, and flexibility. A wire harness, on the other hand, will provide the connectivity between systems in an electromechanical assembly, such as connecting a power supply to a motherboard.

With the documentation in hand, you should expect your contract manufacturer to follow a general process in building your wire cable harness assembly:

Design review: First off, your CM will examine your bill of materials and other documentation to make sure that everything they need is in place. They will also evaluate your specified parts to see if those are the best choices due to cost, availability, and performance. If not, they will search for available replacements.
Materials preparation: Once the bill of materials is finalized, the CM will next purchase the components and materials needed for production and test of the harness.
Assembly documentation: At the same time as procurement, the CM will be creating assembly documentation for the manufacturing floor based on your input. This will include detailed assembly steps, images and illustrations, and test procedures. Additionally, the assembly panel will be created with all the necessary pegs set at the specified locations.
Wire harness production: Now, the harness will be built. The assembly technicians will cut the PVC insulated wires to length, and lay it out on the assembly panel according to the build instructions. Connectors will be added, bundles of wires will be tied together, and labels will be attached.
The Dos and Don’ts of Having Your Wire Harness Built
The component manufacturer usually provides termination recommendations for how the high temperature wires should be attached. Be sure, then, to use those recommendations—such as stripped and bare or stripped and tinned—as that is what the component is built for. The same goes for torque values on fasteners, in which you should also use the manufacturer’s recommended values.

Before you install a SATA hard drive, be sure you have the right cables and slots available on your motherboard. Here's what you need to know.



Consider your use case: If you need a large amount of storage at an affordable price and don't plan on using it as an everyday drive running your operating system, i.e. it doesn't need to be ultra-fast, then a regular HDD drive is the right choice. In that case, you'll want a connection compatible with your motherboard, most likely SATA connector. If you're looking for the fastest possible drive and neither price nor storage capacity are an issue, consider an SSD and check whether your computer has a PCIe slot.




2. SATA DATA and Power Connectors
This article assumes you have a modern motherboard that no longer has IDE connectors. IDE drives haven't featured in consumer computers for some time. The overwhelming majority of computers and motherboards sold in recent years will focus solely on SATA drives (with a few exceptions, of course). Let's familiarize ourselves with the SATA 7P connector and port.

The left connector is for data (typically a red cable), while the second powers your drive. It is possible to buy an all-in-one, 22-pin SATA 15P cable that combines both connectors (but is less flexible).


A reader notes that you should "never use the Molex (4-pin) to SATA power adapter" because "most hard drives and solid state drives require the orange 3.3V wire to board to supply power for the drive electronics." This may cause the drives to fail at spinning up or registering in the computer's BIOS, Device Manager, or Disk Management. Thank you for the heads-up, Doc!

Consequently, some modern HDDs have done away with 4-pin Molex power inputs and now offer just a SATA power input. A SATA SSD will arrive with only a SATA power connector and a data transmission cable.

insecticide, any toxic substance that is used to kill insects. Such substances are used primarily to control pests that infest cultivated plants or to eliminate disease-carrying insects in specific areas.




Modes of penetration
Stomach poisons are toxic only if ingested through the mouth and are most useful against those insects that have biting or chewing mouth parts, such as caterpillars, beetles, and grasshoppers. The chief stomach poisons are the arsenicals—e.g., Paris green (copper acetoarsenite), lead arsenate, and calcium arsenate; and the fluorine compounds, among them sodium fluoride and cryolite. They are applied as sprays or dusts onto the leaves and stems of plants eaten by the target insects. Stomach poisons have gradually been replaced by synthetic insecticides, which are less dangerous to humans and other mammals.

Contact poisons penetrate the skin of the pest and are used against those arthropods, such as aphids, that pierce the surface of a plant and suck out the juices. The contact insecticides can be divided into two main groups: naturally occurring compounds and synthetic organic ones. The naturally occurring contact insecticides include nicotine, developed from tobacco; pyrethrum, obtained from flowers of Chrysanthemum cinerariaefolium and Tanacetum coccineum; rotenone, from the roots of Derris species and related plants; and oils, from petroleum. Though these compounds were originally derived mainly from plant extracts, the toxic agents of some of them (e.g., pyrethrins) have been synthesized. Natural insecticides are usually short-lived on plants and cannot provide protection against prolonged invasions. Except for pyrethrum, they have largely been replaced by newer synthetic organic insecticides as technical products.


The organophosphates are now the largest and most versatile class of insecticides. Two widely used compounds in this class are parathion and malathion; others are Diazinon, naled, methyl parathion, and dichlorvos. They are especially effective against sucking insects such as aphids and mites, which feed on plant juices. The chemicals’ absorption into the plant is achieved either by spraying the leaves or by applying solutions impregnated with the chemicals to the soil, so that intake occurs through the roots. The organophosphates usually have little residual action and are important, therefore, where residual tolerances limit the choice of insecticides as soil disinfectant. They are generally much more toxic than the chlorinated hydrocarbons. Organophosphates kill insects by inhibiting the enzyme cholinesterase, which is essential in the functioning of the nervous system.

Carbamates

The advent of synthetic insecticides in the mid-20th century made the control of insects and other arthropod pests much more effective, and such chemicals remain essential in modern agriculture despite their environmental drawbacks. By preventing crop losses, raising the quality of produce, and lowering the cost of farming, modern insecticides and fungicide increased crop yields by as much as 50 percent in some regions of the world in the period 1945–65. They have also been important in improving the health of both humans and domestic animals; malaria, yellow fever, and typhus, among other infectious diseases, have been greatly reduced in many areas of the world through their use.

But the use of insecticides has also resulted in several serious problems, chief among them environmental contamination and the development of resistance in pest species. Because insecticides are poisonous compounds, they may adversely affect other organisms besides harmful insects. The accumulation of some insecticides in the environment can in fact pose a serious threat to both wildlife and humans. Many insecticides as formulation products are

Many chairs for gamers look like they belong on a racetrack. But the flashy aesthetics are secondary. The true value is the ergonomic support these models provide. If you suffer from back pain in a standard office chair, a gaming chair is one of several upgrades can help. Here we compare racing-style gaming chairs vs office chairs. Learn which type is a better fit for your needs.

Head-to-head, a gaming chair is more visually striking than a standard office chair. It stands out with a bucket seat, tall backrest, thick padding, and support pillows. Meanwhile, a generic office chair typically comes with a padded fabric seat and mid-back support.



Today, sedentary lifestyles are endemic. People spend the majority of their days sitting. There are consequences. Health issues like lethargy, obesity, depression, and back pain are now common. Gaming chairs fill a crucial need in this era. Learn about the benefits of using a gaming chair. It’s true! Upgrading from a cheap office chair can help you feel better, sit longer, and be more productive.

The bottom line is that human bodies work best when active. Despite that, the typical desk worker spends as much as fifteen hours sitting each day. Compounding that problem is how employees sit while at work.

Most offices equip their staff with cheap, traditional office mesh chairs. These come with fixed armrests and a fixed backrest that doesn’t recline. This style of chair forces users into static sitting positions. When the body tires, the user must adapt, instead of the chair.



Ergonomic advantages of a kids gaming chair and adults gaming chair
Standard office chairs force users into static sitting positions. Over full-time sitting hours, that leads to poor posture, joint strain, lethargy, and discomfort. In stark contrast, gaming chairs are “ergonomic”.

That means they come with adjustable components that meet modern ergonomic standards. Those emphasize two essential qualities. First, the presence of adjustable parts that support a healthy sitting posture. Second, features that promote movement while sitting.

A crane is a machine that is used to lift and move heavy loads, machines, materials, and goods for a variety of purposes. They are used in all different sectors of industry, from construction to manufacturing to shipbuilding and material loading. Cranes are common along skylines as they are necessary to build the skyscrapers we so often see in our cities today. And cranes can be debided into different types such as Overhead Crane, Gantry Crane& and Port Crane.

While there are many different types of cranes, there are a few basic components or Crane Accessories like Hoist and Trolley worth mentioning. The main parts that can be found on a crane are as follows.
The Boom
The boom is the most recognizable part of a crane. The boom is a long arm that can either be telescopic or fixed. They take on a variety of roles depending on the type of crane and how it is built. They are able to work without jibs and are sometimes the main component on a crane. The primary purpose of the boom is to lift, move and position material. They bear the majority of the load and are responsible for determining the reach of the crane.

The Jib
The jib crane is the lattice-type structure attached to the end of the boom. Using a lattice-type build helps to reduce the weight it adds to the front of the boom. It is fixed in length and cannot be extended or retracted like a boom can. Some versions of mobile cranes have a jib fixed to the end of the boom to help move and lift materials. The jib or jib arm has one main purpose: to help keep the material clear of the main support so that it doesn't hit it while being moved. That being said, jibs are not always required and are often looked at as extra pieces that can be used when needed.

The Rotex Gear
The Rotex gear is the mechanism below the cab of the crane. It allows the cab and boom to rotate left and right. A simple movement, but incredibly important for the function of the machine.

Counterweights
The name "counterweight" pretty much describes the purpose of them: to counter the weight on the front of the crane while lifting material to prevent tipping. They help add stability to the machine and generally increase stability. Many cranes have adjustable counterweights so that they fit the specific requirements of a load or job. On tower cranes, for example, the counterweight can be seen at the other end of the jib.

Outriggers
Outriggers may be one of the most important factors for crane safety. The function of an outrigger is to supply additional support. The purpose of an outrigger is to distribute the load of the crane over a large enough area so that the crane itself doesn’t tip over or become unstable. All outriggers should either meet or exceed the weight requirements of a crane or job. Outriggers do not compensate for unstable land. OSHA requires cranes to be assembled on firm ground that is drained and graded sufficiently. Supporting outriggers are meant to be used in conjunction with proper ground standards and do not make up for unstable ground.

Reinforced-Steel Cable
In order for cranes to actually lift and move material, they require some kind of line or rope to do the actual lifting. In the case of cranes, this material is a reinforced steel cable. Steel ropes were first used for mining hoists in the 1830s. The wires used today are highly reinforced, resistant to corrosion, absorb any movement or force, and have extremely high breaking points.

The Hook
Finally, the crane must have some way for materials to be attached to it. The most typical way this is done is through a hook. The lifting hook on cranes is usually equipped with a safety latch to prevent the material from slipping off the hook in transit. Crane lifting hooks are often made of steel or wrought iron. Hooks for heavy-duty cranes and loads are usually heat-treated and forged in order to make the hook as strong as possible.

Molybdenum metal is usually produced by powder metallurgy techniques in which Mo powder is hydrostratically compacted and sintered at about 2100°C. Hot working is done in the 870-1260°C range. Moly forms a volatile oxide when heated in air above about 600°C and therefore high temperature applications are limited to non-oxidizing or vacuum environments.

[url=http://www.tungsten-moly.com/molybdenum-alloy/]Molybdenum Alloys have excellent strength and mechanical stability at high temperatures (up to 1900°C). Their high ductility and toughness provide a greater tolerance for imperfections and brittle fracture than ceramics.

The unique properties of molybdenum alloys are utilised in many applications:
High temperature heating elements, radiation shields, extrusions, forging dies, etc;
Rotating X-ray anodes used in clinical diagnostics;
Glass melting furnace electrodes and components that are resistant to molten glass;
Sprayed coatings on automotive piston rings and machine components to reduce friction and improve wear.

For specialised applications, Mo is alloyed with many other metals like Lanthanated Molybdenum Alloy:
Mo-tungsten alloys are noted for exceptional resistance to molten zinc;
Mo is clad with copper to provide low expansion and high conductivity electronic circuit boards;
Mo-25% rhenium alloys are used for rocket engine components and liquid metal heat exchangers which must be ductile at room temperature.

Except for Molybdenum, Tungsten is also a popular metal. Tungsten is an invaluable element in the alloying process, where elements are blended to form new and improved metals known as alloys. Tungsten provides a unique contribution, as it imbues exceptional strength, corrosion resistance, and other useful properties to base metals. Besides being a great alloying element, tungsten can also be the base for its own alloys.

Tungsten alloy
Tungsten alloys, sometimes referred to as heavy alloys, are usually 90-97% tungsten with the rest of its composition being a matrix of metals which improve the ductility and machinability of the resulting alloy. There is no true naming standard for these alloys, as they are set individually by the manufacturer and are not superimposable onto a general scheme such as with the alloys of steel or aluminum.


In addition, there are other kinds of Tungsten alloys like Tungsten Heavy Alloy and Copper Tungsten Alloy are more and more popular. And in the industrial production, other metals like Tantalum, Titanium, Niobium and Chromium are all applied more and more often.

Fruit Vegetable Washing Mahcine is mainly used in washing fruits or vegetables, it is an essential equipment on the fruit and vegetable juice processing line. Fruit washer machine is also widely used in the processing of varied fruit products. To ensure the quality of fruit products or fruit juice, clean fruit is very important, so the washing of fruit is essential.




Besides, when producing the fruits or vegetables, another equipment called Fruit Vegetable Cutting Machine is worth to mention as well. Fruit Vegetable Cutting Machine is currently the most advanced machine in China specialized for slicing vegetables and fruits. The vegetable slicer machine has wide applications. It can cut potato, cucumber, apple and other vegetables and fruits into the round or diagonal slice. The number, diameter, and angle of the feeding inlet could be customized. There is no restriction on the thickness of the vegetables or fruits.

The machine is mainly composed of frame, the feed inlet, rotating cutter head, motor, and transmission part. Put the material into the feed inlet, then the high speed rotating cutter will cut the material into slices.
Attention:
1. It's strictly forbidden to put metal objects or tools into the feed inlet of the fruit slicer machine.
2. The vegetables or fruits to be cut should be washed beforehand. Clay or sand is not allowed to be attached to avoid damaging the cutter.
3. It's strictly forbidden to put your hands into the feed inlet of the industrial fruit slicer while feeding the raw materials.
4. The switch must not be splashed while cleaning the machine.
5. Check and change the v-belt in case the commercial vegetable slicer runs powerlessly.

For the fruits and vegetable processing industry, there are many Fruit and Vegetable Processing Machinery needed during the process. Beside the machine mentioned above, others like Fruit and Vegetable Peeling Machine, Fruit Vegetable Juice Machine, Fruit and Vegetable Sorting Machine, etc. Also, with the improving of the living standard, food producing industry like cake and snake become more and more popular nowadays, so the equipments such as Food Snack Machine, Dough Snack Processing Machine, Cake Processing Machine and Snack Food Processing Machine are commonly seen.
