Background: Expression of virus coat protein (CP) in Escherichia coli often leads to production of partially folded aggregated proteins which are called inclusion bodies. Grapevine fanleaf virus (GFLV) is one of the most serious and widespread grapevine virus diseases around the world and in Iran.Objective: The main objective of this study was to find a s...

OBJECTIVES To find evidence, either corroborating or refuting, for many persisting beliefs regarding the feasibility of carrying out surgical randomised controlled trials with a placebo arm, with emphasis on the challenges related to recruitment, funding, anaesthesia or blinding. DESIGN Systematic review. DATA SOURCES AND STUDY SELECTION The analysis involved studies published between 1959 ...

In biotechnology has been concentrated to review alternative routes for the production of natural compounds. Plant cell culture systems are viable alternatives for the production of secondary metabolites that are of commercial importance in food and pharmaceutical industries. However, relatively very few cultures synthesize these compounds over extended periods in amounts comparable to those fo...

Withania somnifera (L.) Dunal is an important medicinal plant with many pharmaceutical and therapeutic uses ranging from immunomodulation to anticancer property. Field cultivation of W. somnifera is time consuming and it not able to meet current global demands. For commercial production of withanolides, field grown plant materials have generally been used but the quality and uniformity in the l...

In the Andapa region of northeast Madagascar, smallholders cultivating swidden hill rice (tavy) for subsistence are pressing against neighboring nature reserves. A dominant policy approach to reducing this pressure requires that smallholders abandon tavy and purchase rice from proceeds obtained from their environmentally sustainable commercial crops, vanilla and coffee. Economic liberalization ...

Early developments in commercial hatchery technology, artificial incubation and brooding, marketing, diagnostic testing, and key infrastructure improvements from 1900 to 1950 contributed to the growth and present prominence of the poultry industry in the Shenandoah Valley and its importance in the agricultural economy of Virginia. In 2003, Virginia ranked 5, 9, and 31 in the nation for commerci...

It remains unlikely that any government or group of governments will make the long-term funding commitments necessary to return to the Moon in support of scientific goals or resource production. If a lunar base is to be established within the foreseeable future, it will support commercial production and use of unique energy resources. Business plan development for commercial production and use ...

This paper is devoted to simulate the arc movement in the quenching chamber of the low-voltage circuit breaker. Based on a group of governing equations, a three-dimensional (3-D) arc model is built and solved by a modified commercial code. According to the simulated results, some phenomena such as a ‘bulge’ in front of the arc column, a tail in the rear of the arc column, arc shrinkage near the...

Discrete groups of isometries provide a rich class of groups for detailed study in an undergraduate course in abstract algebra. After developing some geometric tools, we illustrate several important ideas from group theory via symmetry groups. In particular, we consider conjugation, homomorphisms, normal and nonnormal subgroups, generators and relations, quotient groups and direct and semidirec...
