  • The dual fluidized beds experimental set up is made of transparent perspex material. The system consists of a fast bed riser, a cyclone to separate the solids, a down comer with a L- valve, a bubbling fluidized bed and a return pipe with another L-valve. The system is shown schematically in Fig 1. The solids after passing through the fast bed riser gets separated in the cyclone, descend downwards through the down comer and enter the bubbling bed reactor through the L-valve. A part of bed materials in the bubbling bed system are then transferred back into the...

  • The present volume ofModern Aspects of Electrochemistrybrings readers the newest developments and achievements in the product ion of metallic powders by electrochemical and electroless methods from aqueous solutions. Although the deposition of metallic powders from aqueous solutions was intensively studied for years, the last summarized results (Calusaru) on this topic were published in 1979. Electrochemically and chemically produced metal powders from aqueous solutions are of high purity.

  • The oxide reduction diffusion (ORD) procedure has recently been applied in synthesizing hydrogen storage materials AB5 for Ni-MH batteries. Starting from metal hydroxides and La oxalat precursor, superfine powder alloys LaNi5, LaNi4.5Co0.5 and LaNi3.87Mn1.13 were obtained by this “soft-chemistry” route. Chemical composition, structure and morphology of alloy phases were examined by different analysis techniques such as AAS, EPMA, X-ray and TEM. The H2-absorption and desorption behavior of crystalline products was determined by Sieverts’ method.

  • Plastic products are indispensable in our everyday life. Today, the injection molding is the most used method for producing plastics parts. Using injection molding process, the plastic materials can be melted or remelted and injected at high pressure into the mold cavity to produce parts with desired shape. I started my study on injection molding seven years ago. When I was an undergraduate student, I got acquainted with mechanics and control. Then, injection molding opened a new and interesting world for me to know mechanical engineering and plastic materials....

  • Sintering refers to the science and technology of production objects from fines or powders. Being a very complex phenomenon, sintering covers a broad subject field and combines chemistry, physics and mechanics. Sintering deals with various material systems such as metals, non-metals, ceramics, polymers, and their combinations. Processes of sintering may occur in a wide temperature range - in a solid state as well as with participation of a liquid phase.

  • POWDER METALLURGY has been called a lost art. Unlike clay and other ceramic materials, the art of molding and firing practical or decorative metallic objects was only occasionally applied during the early stages of recorded history. Sintering of metals was entirely forgotten during the succeeding centuries, only to be revived in Europe at the end of the 18th century, when various methods of platinum powder production were recorded (

  • The standard is intended for the development of organic production and trade in the East African region. The standards can be a platform for a common label for organic products in East Africa and for developing consumer trust. The standard also formulates standpoints which can be used in international negotiations on standards. Further, it can be a basis for equivalence agreements with other countries and regions. The East African organic products standard has been written in a way to make it easy for the reader and user to access and understand.

  • The probiotic bacteria must be viable to affect the health, but the non-viable bacteria could also affect the immunological status of the host. It is believed that the arrival of probiotic bacteria with food to different parts of intestine can increase probiotic bacteria adherence and the rate of colonization. Food products may contain many forms of probiotic bacteria, including culture concentrate that is added to a food (dried or deep-freeze form), the fermented or non-fermented food products, and dietary supplements in the form of drug products-powder, capsules or tablet.

  • Among food products probiotic bacteria is distributed in a variety of products including fermented milks, ice cream, various types of cheese, baby-food milk powder, frozen dairy desserts, whey-based beverages, sour cream, butter milk, normal and flavored milk, and concentrated milk. Currently, yogurt is the major probiotic which is sold to consumers. Mortavasian et al. attempted to characterize the probiotic microorganisms used in food products exploring the most common, bifidobacteria and lactic acid bacteria.

  • Magnesium is the lightest of all the metals and the sixth most abundant on Earth. Magnesium is ductile and the most machinable of all the metals. Magnesium alloy developments have traditionally been driven by requirements for lightweight materials to operate under increasingly demanding conditions (magnesium alloy castings, wrought products, powder metallurgy components, office equipment, nuclear applications, flares, sacrificial anodes for the protection of other metals, flash photography and tools). The biggest potential market for magnesium alloys is in the automotive industry. ...

  • The results of scenario S4 are presented in relative terms to scenario S3, i.e. the baseline scenario in year 2020. Therefore, this analysis isolates the effects of the abolition of the milk quota system in the EU-27 on specific economic indicators at MS and regional level. Key results of scenario S4 are that milk production increases by about 4.4% in the EU-27, and EU raw milk prices decline by 10%. Production of butter, skimmed and whole milk powder would increase by 5-6% while their prices would decline by about 6-7%. The production of cheese and fresh milk products...

  • Many soils which have received manure or synthetic applications over a number of years contain relatively high levels of soil phosphorus. In soils which have not been so fertilized, phosphorus levels may be low. Rock powders suc as colloidal phosphate and rock phosphate can be applied to build up the phosphorus-supplying power of a soil over time. However, these products become available to plants very slowly, and cannot be relied upon to supply adequate phosphorus to a crop the year of application when soil level of phosphorus are low.

  • Corn gluten meal is a natural pre-emergent fertilizer (9.5-0.5-0.5) that reduces the germination and establishment of troublesome annual weeds. It is available as a powder or in granular form. It is 60 percent protein and approximately 10 percent nitrogen by weight. It is a by-product of the wet milling process and commonly used in pet and livestock feed. It can be used in vegetable gardens as a fertilizer and can help with weed control, but be careful. It can damage the germination of your food crops. Use it only after your vegetable seeds are up and young plant roots are...
