Aroma compounds are widely used as additives in many products (food, pharmacy and cosmetics). Most industries applied extraction and distillation to recover aroma compounds from natural sources; however, both suffer from disadvantages (product contamination and energy consumption). Pervaporation (PV), a membrane separation process, is considered as a promising technique to overcome above challenges. This book contains both experimental and parametric studies dealing with the application of PV for aroma compound recovery from aqueous solutions using poly (ether-block-amide) (PEBA) membranes. The effect of process conditions on PV performance (permeation flux and selectivity) were investigated. The solubility and diffusivity of the aroma...

Meat and meat products make important nutritional contribution to the diet of the people. Significant percentage of the recommended dietary allowances for proteins, vitamins-B, magnesium, phosphorous, iron and zinc are contributed by red meat and poultry (Pearson and Brooks, 1978). Primitive men recognized that a meat rich food was for more concentrated than vegetable foods and in early days mankind survived on animal foods, which now a days after development of food science are claimed to be more nutritious than other foods. It is recognized as a highly nutritious food having high quality proteins, a good balance of the essential amino acids and high biological value.The meat is the center of attraction for microorganism especially...

Molecularly imprinted polymers (MIPs) are synthetic polymers possessing specific recognition sites designed for a template molecule. These artificially-generated recognition sites have their shapes, sizes or functionalities complementary to the template, and are capable of rebinding the template in preference to other closely analogue. The main propose of this study is to prepare a series of the molecularly imprinted polymers based on siloxanes for recognized sulfonamide by sol-gel process and to investigate systematically their preparation conditions and the various fundamental properties. This book contains three parts as follows: in first part, the sol-gel molecularly imprinted polymers based on tetramethoxysilane (TMOS) and...

The theoretical principles of anelastic phenomena in solids were formulated for the first time by C. Zener in 1937 – 1938. Virtually at the same time N. N. Davidenkov formulated the principles of the nonlinear mechanics of materials. Special literature operates with various terms for describing inelastic phenomena in solids, for example, internal friction, physical acoustics, absorption of ultrasound, static and dynamic hysteresis loops, internal dissipation of energy, and damping of oscillations. In 1990 De Batist and Magalas suggested a generalized concept for the description of these phenomena known today as mechanical spectroscopy of materials. Mechanical spectroscopy (MS) studies absorption spectra of mechanical energy under the...

High Quality Content by WIKIPEDIA articles! A submarine tender is a type of ship that supplies and supports submarines. Submarines are small compared to most oceangoing vessels, and generally do not have the ability to carry large amounts of food, fuel, torpedoes, and other supplies, nor to carry a full array of maintenance equipment and personnel. The tender carries all these, and either meets up with the submarines at sea to replenish them or provides these services while docked at a port near the area where the submarines are operating. In some navies, the tenders were equipped with workshops for maintenance, and as floating dormitories with relief crews. Unable to operate conventional surface tenders during World War II, the German...

High Quality Content by WIKIPEDIA articles! The Sunset Limited is a passenger train that for most of its history has run between New Orleans and Los Angeles, California, and that from early 1993 through late August 2005 also ran east of New Orleans to Florida, making it during that time the only true transcontinental passenger train in American history. From late August 2005 to the present, the train has remained officially a Florida-to-Los Angeles train, being considered temporarily truncated due to the lingering effects of Hurricane Katrina. Service between Orlando and New Orleans has been suspended. Future service has not been determined. It uses cars of Amtrak's double-deck Superliner fleet. Данное издание не...

It is owned and operated in partnership between South Yorkshire Passenger Transport Executive, who own the infrastructure, and Stagecoach Group who operate and maintain the trams, through their Stagecoach Supertram branded subsidiary. Following a parliamentary act in 1985 authorising the scheme, the system was built by SYPTE at a cost of 240 million, and opened in stages between 1994 and 1995. It was initially operated by South Yorkshire Supertram Ltd, a wholly owned subsidiary company of SYPTE.

During the last decades, supercritical fluid extraction has received especial attention mainly due to its direct application in food, cosmetics and pharmaceutical industries. Regarding to environmental and processing regulations, supercritical fluids are a very attractive alternative to conventional extraction and refining methods. Agricultural processes result in large quantities of several by-products, which are often under utilized. Several organic natural components can be found in food processing by-products and, with additional treatment, can change from a low-value status to a high revenue stream of nutraceutical materials, such as phytosterols, oryzanol, triglycerides, vitamins and aromatic components, which can be used in the...

High Quality Content by WIKIPEDIA articles! Surface-mount technology (SMT) is a method for constructing electronic circuits in which the components (SMC, or Surface Mounted Components) are mounted directly onto the surface of printed circuit boards (PCBs). Electronic devices so made are called surface-mount devices or SMDs. In the industry it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. An SMT component is usually smaller than its through-hole counterpart because it has either smaller leads or no leads at all. It may have short pins or leads of various styles, flat contacts, a matrix of solder balls (BGAs), or terminations on the body of the...

High Pressure Die Casting of aluminium alloys is a technology of critical importance to Australias' global competitiveness in the light metals industry. Its productivity, however, was severely impaired by the rapid degradation of die steels when they encountered molten aluminium entering the die under extreme conditions of high melt velocity and the rapid thermal shock on cooling. The research conducted in this book identified for the first time the benefits of applying advanced plasma- based surface engineering technologies to the treatment of die surfaces. Industrial plant trials proved the success of the innovation which led, through technology transfer, to significant productivity gains. Данное издание не...

The development of composites using carbon fibers as the reinforcement requires surface activated carbon fibers with a durable surface composition. In this work, sized polyacrylonitrile (PAN)-based carbon fibers were modified by Oxy- Plasma treatment, Oxy- fluorination, and Nitric acid treatment in order to improve the interaction between carbon fiber surface and matrix. The effect of different surface treatments was observed by means of contact angle, surface free energy measurement. Surface roughness were seen by the help of Scanning electron microscopy (SEM).The lower contact angle proved the surface hydrophilicity of treated carbon fiber.XPS, Zeta-potential measurements revealed changes in surface chemistry of treated carbon fibers....

It is proposed that by microstructural modification of the surface of Mg alloy ZE41, the corrosion resistance of the alloy may improve. This is based on the assumption that the secondary phase in the microstructure of the alloy is responsible for the corrosion and by removing or reducing the secondary phase, the corrosion resistance of ZE41 would improve. Laser surface treatment and friction stir surface treatment are two techniques employed in the present study to carry out this surface microstructural modification on ZE41. New refined microstructures are formed in the modified zones. Corrosion behavior of the surface modified alloy has been compared with the alloy without surface modification, by eletrochemical corrosion tests and...
