Checking the soil's thermal resistivity tests the soil's ability to conduct or discharge heat. For designing and installing underground pipelines and transmission cables, the correct understanding of the thermal properties of soil or layer of rendered ground is necessary to prevent premature failures. The current provided by a subterranean power cable can dissipate the heat properly. And that is why Sigma is all ready to help provide its clients with Solar Thermal Resistivity Test to meet the Solar Power Target of India. What does Sigma do – 1.        Assists in the planning and construction of underwater pipelines. 2.        Prevents the build-up of heat across power transmission cables. 3.    Measures the heat dissipation properties of the earth in preparation for pipeline construction. 4.        Calculates the best cable requirements for the ground conditions in the region...

  Hydrocarbons of mineral oil (MOHs) are complex chemical blends. MOHs usually come from crude petroleum. They are primarily made up of hydrocarbons saturated with mineral oil (MOSH) and aromatic mineral oils (MOAH). MOSH consists of open, often rammed hydrocarbons and cyclic, saturated hydrocarbons (usually referred to as paraffin) (commonly named naphthene's). MOAH comprises aromatic monocarbons or polycyclic hydrocarbons. In general, Naphthene and MOAH are rather alkylated. The MOAH content can reach up to 35 per cent depending on crude oil source and refining. How does MOAH/MOSH enter Food Products? What are the known contaminant sources? Mineral oils have a wide range of input pathways that span all stages of food production (raw materials, storage and transportation, production, and packaging materials). Adhesives, printer inks, and packaging materials - especially those made of recycled materials - are the main sources of MOSH/MOAH contamination. Machine and hydraulic oils u...

Condoms are the second best thing to happen to humans after sex. Without a doubt, it is one of the most brilliant human inventions. It not only helps you prevent accidental pregnancies, but it also prevents you from STI. Male condoms have been on the market for far longer than female condoms, so, understandably, male condoms are more commonly used, but it is reassuring to know that there is another choice that allows women to be in charge. Women with these needs will protect themselves from disease and motherhood without depending on the guy to use a condom. Female Condom Material - The FC2 internal condom, also known as the female condom, consists of a smooth, thin (nitrile) substance-free of latex, so no allergic reaction is possible. It is inserted within the body to create a removable pocket that restricts the exchange of body fluids between sex partners and direct contact with your skin. In comparison to masculine condoms, the FC2 is pre-lubed on both ends, making both partner...

  How often have you heard the contractors say “how about if we add some more water to the concrete eh?” Well, depending on the conditions that must be followed, adding water to a concrete load may or may not be suitable. If no concrete has been drained except for slump or slump flow testing, a one-time injection of water may be divided into multiple separate adds of water. However, within 15 minutes of the start of the first water addition, all water additions must be completed.  Also, one should make sure that water is pumped in a manner under certain pressure and direction of flow that optimal a mixture of the matter is attained. Hence, keeping in mind the goal, that a homogeneous mixture is achieved, the drum should be turned an additional 30 revolutions at mixing level, or more if possible. The sole The aim of this article is based on strengthening one’s understanding of water-cement proportions and how excess and undesired water additions can influence the concrete's per...

The increased use of lithium-ion battery-powered devices has created a demand for high levels of precision and quality to support a wide range of applications. One evaluation test method utilized to address this demand is charge/discharge cycle testing. The goal of the test is to discover how many times a battery can be used by examining it until it deteriorates after repeated charging and discharging cycles. Under this, the battery is connected to a decade resistor box, the resistance is set to 8 ohms (6.5V and 750mA) to simulate the current draw, and the voltage across the terminal of the battery is measured every 15 minutes with the resistor box connected. The results are collected and a scatter graph can be created to show the relationship of battery discharging. Then high voltage and low voltage disconnected voltages can be determined based on the resulting curve. Required Equipment               ...

  Petroleum, which literally means "rock oil" or "oil from earth" forms from the remains of the plants and animals that lived in the marine environment millions of years ago, is preferable during the Pre-Dinosaur age. Subsequent decomposition of the buried remains of the marine animals by the application of heat and pressure due to the deposition of sand and slit of over them led to the form of the "Crude Oil" or Petroleum. Petroleum is one of the three fossil fuels that occur in our nature. Moreover, these fossil fuels are comprised of a complex mixture of different types of hydrocarbons along with several elemental impurities such as sulfur, nitrogen, oxygen, and many others. However, due to wide variations in the origin of petroleum products, they vary in terms of their physic-chemical properties and appearances, from one oil field to other. While purchasing anything you need to consider three primary aspects; price, service, and quality. However, consi...

Food Shelf Life refers to the product of physical, chemical, and microbiological processes, which are triggered by any of these contributing factors. The product's characteristics, including the quality and consistency of the ingredients, moisture content, and acidity levels, play an important role as external factors such as storage, packaging materials, and transportation of the products. Certain complex factors contribute to the shelf life of food, which is tailor-made by the professionals according to the composition of the products, storage, and packaging.  Food Shelf-Life Testing helps you in defining accurate dates for your products by ensuring that the quality remains acceptable and safe for the consumers. Some of the tests undertaking by the professionals and food testing lab specialists include:  Food-borne microorganisms such as Listeria, Salmonella, E.Coli, Campylobacter, yeasts and molds, Staphylococcus Aureus, Bacillus Cereus, Lactic Acid Bacteria Total viable ...
