The rapid increase in Internet communications’ products such as high-speed switches, SerDes (serial-deserializer) elements and XAUI (X=10G, attachment unit interface) ports has energized the need for process technologies that support both digital and analog (mixed-signal) elements at radio frequencies (RF). In order for these products to be competitive, process technologies that support analog/...

BACKGROUND A constantly growing part of consumers considers the organic foods healthier than the conventional foods. However, so far few nutritional intervention studies in humans are available on the comparison of organic and conventional food products. OBJECTIVE The aim of the present work was to compare the total antioxidant activity of organic versus conventional fruits (apples, pears, re...

traditional agriculture and non-chemical crop production have a long story; however organic agriculture which relies on local and in-farm inputs, with the aim of protecting ecological balances and developing biological cycles on the one hand while regarding regulations and specific standards on the other hand, doesn’t have a very long history. there are numerous environmental reasons for the pr...

Emerging contaminants are distributed in to the environment from various anthropogenic activities. These Emerging contaminants (ECs) are mainly composed of products, such as pharmaceuticals, personal care products (PCPs), surfactants, plasticizers, pesticides etc. The present conventional system of waste treatment are not designed to treat these contaminants. Complex structure of these pollutan...

Brasica napus L. is one of the most important crops in the world, but every year during mechanized harvesting with conventional combines large quantities of the seeds fall to the ground and thus result in a decrease in yield. Therefore, designing and manufacturing a head specific for harvesting this crop is a high priority. In this study, the head of a combine for harvesting fine-grained produc...

The application of the [Pd{C6H3(CH2CH2NH2)-4-OMe-5-κ2-C,N}(μ-Br)]2 complex of 2-methoxyphenethylamine in the Heck coupling reaction was considered under both conventional and microwave irradiation conditions, and their results were compared. This complex is an efficient, stable and non-sensit...

In the past decade, a global demand for products from organic agriculture has increased rapidly. Milk quality is of major interest for all parties. Therefore, the objective of this study was to compare cow performance and product quality in conventional and organic system. Twenty Holstein dairy cows were allotted to one of 2 diet groups, which including: a conventional diet (CON), and an organi...

Increasing material’s strength is of particular importance. Improving material’s mechanical properties such as strength could reduce the size and weight of the structure. The size and weight of the structure are among the effective parameters in design. Since the past a variety of methods have been developed to increase the strength of metals that are capable of increasing metals’ strength to a...
