A majority of viruses are composed of long single-stranded genomic RNA molecules encapsulated by protein shells with diameters of just a few tens of nanometers. We examine the extent to which these viral RNAs have evolved to be physically compact molecules to facilitate encapsulation. Measurements of equal-length viral, non-viral, coding and non-coding RNAs show viral RNAs to have among the sma...

Embryonic development of the pancreas is marked by an early phase of dramatic morphogenesis, in which pluripotent progenitor cells of the developing pancreatic epithelium give rise to the full array of mature exocrine and endocrine cell types. The genetic determinants of acinar and islet cell lineages are somewhat well defined; however, the molecular mechanisms directing ductal formation and di...

to evaluate the effect of zn sulfate foliar application on morphologic and quantitative characteristics of safflower (carthamus tinctorius l.) cultivars, a field experiment carried out in ramin agriculture and natural resources university of khouzestan, iran, in a factorial arrangement in a randomized complete block design with four replications, during 2012-2013. treatments consisted of two sp...

in order to investigate the effects of water deficit at different growth stages of chickpea genotypes, determining the best drought tolerance index and genotypes, an experiment carried out in the saatlu agricultural research station of uromia in 2008-2009. the experiment was split plot based on the randomized complete blocks design with four replications, in which, four levels of irrigation as ...

Polyethyleneimine (PEI) is a common polymer used in many industrial applications and research, especially surface chemistry. It available wide range of molecular weights different degrees branching. classified as linear or branched sometimes the term hyperbranched also used. This description, however, quite rough, which limits possibility to correlate structure PEI its properties. The aim this ...

Sesame (Sesamum indicum L.) seed and oil have long been used widely as healthy foods to supply energy and prevent aging. Some of the main active anti-oxidative constituents in sesame seeds are γ-tocopherol and phenols. The purpose of this study was to investigate the relationship between roasting temperature and time with γ-tocopherol and total phenolic compounds (TPC) of sesame seeds when roas...

1 LIP6, Université Pierre et Marie Curie, 4 Place Jussieu, 75252 Paris Cedex 05, France. [email protected] Abstract. Knowledge about forced moves enables to select a small number of moves from the set of possible moves. It is very important in complex domains where search trees have a large branching factor. Knowing forced moves drastically cuts the search trees. We propose a language an...
