They act asneurotransmitters and have a variety of pharmacological effects on the nervoussystem. Biosynthesis of cannabinoids is one of the nine categories of newpsychoactive substances. It is a synthetic chemical substance, independent ofthe cultivation of c
IndustrialCoil Coatings is a coating product applied to the coating of pre-coated metalcoils, which changes the traditional way of coating metal sheets after formingand processing. Coil coatings are pre-coated on metal coils to form colorcoated steel plates and then processed. They are widely used in buildingmaterials, home appliances and other fields.
Dairy flavors are processed and manufactured from dairy products such as milk, butter, cheese, cream, etc. These flavoring agents are specially used to enhance the flavor and creaminess of dairy products. In non-dairy ingredients and product formulations, dairy flavors are used in combination with other natural flavors to provide better taste to the final product. Dairy flavors have a variety of f
Urological X-ray is a method of diagnostic examination of urological disorders using X-rays. Continuous advances in X-ray examination methods are driving the development of modern urology, such as intravenous urography, renal arteriography, computed tomography and the combined use of various imaging techniques have largely improved urological diagnostic techniques and advanced the development of u

Itconsolidates disparate learning resources into a single portal. A learningexperience platform is a cloud-based offering that delivers a personalizedlearner experience to employees. The platform combines internal digitallearning assets of a company wi
DAM software enables users to upload, store,organize, manage, share and track all digital assets from one source. Usually,it gives users access to it on any device, anywhere. Make regular backups andsynchronizations to keep all the files safe and protected. In addition,administrator users can grant or deny access to specific files through specificroles with access control. DAM software is also use
A French press, also known as a press pot, coffee press, or coffee plunger, is a coffee brewing device, while it can also be used for other tasks. In a word, French press is a coffee cooking tool made of glass and metal mesh. French presses are more portable and self-contained than other coffee makers. Travel mug versions exist, which are made of tough plastic instead of the more common glass, and
HVAC refers to heating, ventilation and air conditioning, which has a wide influence in the world of architectural design and engineering as well as manufacturing. Heat transfer, engineering thermodynamics, and fluid mechanics are the basis of its basic theory. Its research and development direction is to provide a more comfortable working and living environment for human beings. HVAC software all
Automotive torque actuator motors can be dividedinto pneumatic motors and electric motors according to different types. Drivenby air, pneumatic motors use vacuum or compressed air to convert energy intolinear or rotary motion. Air pressure and flow determine speed and torque. An electric motor is a device that converts electrical energy intomechanical energy, and can reuse mechanical energy to gen
Blood sugar of diabetes patients is not easy tocontrol. In severe cases, it can damage many parts of the body, including thenerves and blood vessels in the feet. As a result, diabetic patients have anincreased risk of foot disease. Diabetic shoes, also called therapeutic shoes, is specifically designed for footdiseases of diabetic patients, which comfortable materials and scientific workmanshipcan
Demineralized whey powder is a whey product with dissolved minerals and water removed. The main components of whey powder are whey protein and lactose.
Rubberplays a vital role in the global economy, with major applications in theautomotive, consumer goods, manufacturing, and medical industries. Naturalrubber is collected from rubber trees, is transformed through remilling plantsthat wash it (removing leaves, insects, dirt, etc.), blend it (to ensureconsistency), dry it and package it before selling it on in the form of eithersmoked rubber sheets
LBOcrystal is one of the most versatile nonlinear optical crystal materialsavailable. It has a very broad transmission range from vacuum UV to midinfrared, a very high damage threshold (actually the highest among the commonnonlinear crystals) and is capable of noncritical phase matching (NCPM) in thenear IR region. In addition, the crystal has stable chemical properties, highmechanical hardness, a
Heparin Sodium is formed by a heterogeneous group of straight-chain anionic mucopolysaccharides called glycosaminoglycan. It can be described as a glycosaminoglycan sulfate. Heparin delays the coagulation of fresh blood. Heparin is strongly acidic because of its content of covalently linked sulfate and carboxylic acid groups. In heparin sodium, the acidic protons of the sulfate units are partially
Laweson reagent, or LR, is a chemical compoundused in organic synthesis as a thiation agent, which was first prepared by thereaction of aromatic hydrocarbons with tetraphosphorus decasulfide in 1956, andwas named after the Swedish chemist Sven-Olov Laweson research on its reactionwith organic compounds. It hasmany advantages over the classical thionating reagent P4S10 such as mildreaction conditio
3D Optical surface profilers are a type of profilometer that uses a non-contact technology. They are typically built on advanced optical microscopes, providing the dual advantages of excellent imaging and no contact with the surface being measured. They use a variety of light sources, usually using high-brightness LEDs, to illuminate the sample and sophisticated cameras to capture the images which
PolyimideVarnish is a polyamic acid solvent resulting from the condensationpolymerization reaction of aromatic diamine and anhydride. Polyimide membraneswith excellent characteristics are produced by applying a polyimide varnish tothe base materials and then drying or heating it at high temperature.
