Polyhydroxyalkanoates (PHAs), a biodegradable polymer, has many industrial and medical applications such as heart valves, scaffold, suture and drug delivery. Because of their structural diversity and close analogy to plastics, PHAs have gained major interest over the world. Natural isolates, recombinant bacteria, and plants have all been found to improve the quality, quantity, and economics of PHA production. Their biodegradability makes them an especially appealing synthetic plastic substitute. PHB biosynthetic genes phbA, phbB, and phbC are grouped and systematised into a single phbCAB operon. In terms of alignment and clustering of the relevant genes, the PHB pathway varies greatly across bacterial genera. In this regard, the enzymes appear to have a high degree of sequence preservation. The structural studies further improve the mechanism of action of these enzymes and helped in improving and choosing the good candidates for increased production of PHB.

Authors from the Christian Right in the USA situate the September 11 attack on New York and Washington within God's intentions to bring America into the divine schedule for the end of the world. This is true of Pat Robertson and Jerry Falwell, and other leading figures in the ‘Christian Coalition’. This article analyses how Christian fundamentalists assess the roles of the USA, the State of Israel, Islam, Iraq, the European Union and Russia within what they perceive to be the divine plan for the future of the world, especially against the background of ‘9/11’. It argues that the ideas of the Christian Right and of President George W. Bush coalesce to a high degree. Whereas before 9/11 many American mega-church preachers had aspirations to direct political life, after the events of that day the President assumes some of the roles of a mega-religious leader.

Religious Landscape

In recantation of his earlier approach, Peter L. Berger now claims: ‘The world today, with some exceptions […], is as furiously religious as it ever was, and in some places more so than ever.’ The most important exception that Berger refers to is Western Europe. The introduction to Part II provides an overview of the religious landscape in Western Europe. The data show that the current religious situation in the countries of Western Europe is in fact subject to considerable variation. It would therefore be erroneous to describe Western Europe as secularized. At the same time, the data reveal that there have been clear secularization tendencies over the last few decades. To grasp the diversity of religious tendencies, Part II deals with three cases: West Germany with moderate downward tendencies, Italy with a considerably high degree of stability, and the Netherlands displaying disproportionately strong secularizing tendencies.

AbstractCaenorhabditis elegans has become one of the most widely used model research organisms, yet we have little information on evolutionary processes and recent evolutionary history of this widespread species. We examined patterns of variation at 20 microsatellite loci in a sample of 23 natural isolates of C. elegans from various parts of the world. One-half of the loci were monomorphic among all strains, and overall genetic variation at microsatellite loci was low, relative to most other species. Some population structure was detected, but there was no association between the genetic and geographic distances among different natural isolates. Thus, despite the nearly worldwide occurrence of C. elegans, little evidence was found for local adaptation in strains derived from different parts of the world. The low levels of genetic variation within and among populations suggest that recent colonization and population expansion might have occurred. However, the patterns of variation are not consistent with population expansion. A possible explanation for the observed patterns is the action of background selection to reduce polymorphism, coupled with ongoing gene flow among populations worldwide.

The Way

This article addresses the work of the German artist Hannah Höch in the light of the struggle for abortion rights in the Weimar Republic. I attempt to show how Höch’s uses of the technique of photomontage can be read as a way of introducing a distance between the work and the viewer that allows us to question the beliefs we use to make sense of the world. Specifically, I discuss her photomontage Mutter (‘Mother’), a version of a photograph taken by John Heartfield, and some of her writings and interviews. I also examine closely the material conditions and political debates in which Höch’s work – as a social practice – developed. After a brief introduction and a methodological outline, I present Höch in the context of Berlin Dada and summarise the main underlying arguments of my hypothesis. Namely, that the major interest of Höch’s photomontages lies in the complex articulation of activism and philosophy, and in the way in which they put mainstream categories into question by ‘distancing’ fragments of reality.

AbstractIn a comparative study the issue is raised about the relationship between the construction of the saviour-image in Christianity, Buddhism, Zoroastrianism and Hinduism. The historical links between these traditions are highlighted and then the article proceeds to argue that when compared, the projections of the images of Jesus and Buddha, Jesus and Zoroaster and Jesus and Krishna exhibit a high degree of similarity. In the process questions are asked about the nature of religion and the value of comparative study.

AbstractThe basidiomycete fungus Lentinula novae-zelandiae is endemic to New Zealand and is a sister taxon to Lentinula edodes, the second most cultivated mushroom in the world. To explore the biology of this organism, a high-quality chromosome level reference genome of L. novae-zelandiae was produced. Macrosyntenic comparisons between the genome assembly of L. novae-zelandiae, L. edodes and a set of three genome assemblies of diverse species from the Agaricomycota reveal a high degree of macrosyntenic restructuring within L. edodes consistent with signal of domestication. These results show L. edodes has undergone significant genomic change during the course of its evolutionary history, likely a result of its cultivation and domestication over the last 1000 years.

: Nitrogen-containing heterocycles attract the attention of chemists due to their multifarious activities. Amongst all, pyrimidine plays a central role and exhibits a broad spectrum of biological activities. Literature is replete with the various aspects of synthetic development in pyrimidine chemistry for a wide array of applications. It aroused our interest to compile various novel and efficient synthetic approaches towards the synthesis of pyrimidine and its derivatives. Pyrimidine derivatives are broadly useful as therapeutic agents, owing to their high degree of structural diversity. They have been recorded to possess a diverse range of therapeutic activities, viz. anticancer, anti-inflammatory, anti-HIV etc.

<p>The study aimed at revealing the motives and the obstacles of using internet as a source of<br />learning by the human colleges at WISE. And to achieve the study’s goals , a questionnaire<br />was developed consisting of 40 items; 20 items addressed motives of using internet as source<br />of learning and other 20 items addressed obstacles of using internet as a source of learning .<br />The sample of the study which consisted of 520 male and female students was selected<br />randomly in the second semester for 2012/2013. After data were collected, they were<br />analyzed using descriptive methods, t-test and ANOVA. Results showed the motives of using<br />internet ranged from high degree to moderate. The degrees of obstacles facing using internet<br />were moderate.<br />The researcher recommended the necessity of activating the students’ use of internet with<br />their teachers’ guidance, facilitating the use of internet by increasing the number of computer<br />labs and supervisors, in addition to provide flexible and easy electronic programs for studying<br />university courses.</p>

The application of automatic data processing techniques to air traffic control has been espoused by both operational and research and development groups dealing in air traffic control throughout the world. As far back as 1947, in the U.S.A., the Special Study Group, SC-31 of the Radio Technical Commission for Aeronautics suggested that a high degree of automation be applied—including rigid control of all flights and their times of arrival.
