Objective: Taro (Colocasia esculenta L. Schott) is a perennial root crop that belongs to Araceace family.  It is widely cultivated as a staple food in Africa, Asia and pacific Islands. Despite its importance, there is limited information on many aspects of the crop. In order to obtain data that can support improved and sustainable taro production, a field trial was conducted to study t...

Background:                             The use of new technologies in the field of drug discovery and development plays an important role in introducing new and effective drugs, optimizing the properties of existing drugs and, in general the development of various drug-dependent industries, as well as the general health of human, animal and plant communities. These methods provide new drugs at...

manure and putreseible garbage are some of the main sources of pathogenic germs in countryside’s. on the other hand, demand for fertilizer and energy increases in rural areas every day. to study potential of cow manure for these requirements a 16,5m3 pilot plant was designed and constructed as fermentation tank near animal husbandry of karaj agriculture faculty. some 260kg cow manure and water ...

The paper describes the main drive systems of an iron ore pelletizing plant and related important design aspects. It is shown how today’s drive systems provide the desired flexibility for the process and lead to high energy efficiency and system reliability. With respect to electric drives expansion projects have many technical issues in common with green-field installations. However, there are...

Natural-based drugs are the important bioactive substances that have been used for prevention and treatment of diseases. Natural products should be prepared in commercial scale from relevant medicinal plants. Hence, large amounts of the plants have been needed for extraction and isolation of compounds of natural origin. Plant cells technology is the best strategy for the production of the plant...

The lot-sizing and production scheduling problem in a real-life multi-product yoghurt production line is addressed. A new discrete/continuous time representation mixedinteger linear programming model, based on the definition of families of products, is presented. It is mainly optimized the packaging stage while timing and capacity constraints are imposed with respect to the pasteurization/homog...

Manure not only supplies many nutrients for crop production, but it is also a valuable source for increasing soil organic matter content and improving soil structure. To increase organic manure content as well as improve the wheat production adding plant residues and livestock to soil is necessary. The experiment was conducted in Shavoor Research Station to determine seed yield and soil physica...

abstract nitrogen is a key nutrient in plant growth and it is necessary for amino acid synthesis. sulfur has very important role in the biosynthesis of the alliums flavor and pungency precursors and potassium improve crop yield and quality. in order to study the effect of ammonium nitrate and potassium sulfate on concentration some of the mineral elements in onion (allium cepa l. azar shahr cv....
