The influence of the enhanced vector meson sector on the properties of the matter of neutron stars

This paper gives an overview of the model of a neutron star with non-zero strangeness constructed within the framework of the nonlinear realization of the chiral $SU(3)_{L}\times SU(3)_{R}$ symmetry. The emphasis is put on the physical properties of the matter of a neutron star. The obtained solution is particularly aimed at the problem of the construction of a theoretical model of a neutron star matter with hyperons that will give high value of the maximum mass.Comment: 13 pages, 17 figure

Generalization of the Four Roles Found in Adult Children of Alcoholics to a College Population

The Children\u27s Roles Inventory was developed to assess the four theoretical children\u27s roles found not only in alcoholic families but in all families regardless of parental alcoholism: the Hero, Mascot, Lost Child, and Scapegoat. A sample of 266 college students, with 19% indicating parental alcoholism, completed the CRI and measures of self-actualization and self-esteem to verify any differences between the identified groups of adult children of alcoholics, adults from nonalcoholic families and the four roles within. Demographic information was also obtained including: gender, age, and whether the individual was a member of a fraternity or sorority. Significant differences were found in these areas: COA-Scapegoats scored higher on the CRI than nonCOA-Scapegoats for this subgroup; Heroes, Mascots, and the Blended subgroup scored higher than Lost Children in self-esteem; and males scored higher in self-esteem than females. These results indicated that the four theocratical children\u27s roles can cautiously be applied to a college population with few empirical differences. A suggestion for further investigation of the use of the CRI was to administer the measure to high school or junior-high school students. Questions still remain of how appropriate the CRI is for labeling individuals who do not come from alcoholic families

Isolation, Preliminary Characterization and Preliminary Assessment of Scale-Up Potential of Photosynthetic Microalgae for the Production of Both Biofuels and Bio-Active Molecules in the U.S. and Canada: Cooperative Research and Development Final Report, CRADA Number CRD-10-372

Combustion flue gases are a major contributor to carbon dioxide emissions into the Earth's atmosphere, a factor that has been linked to the possible global climate change. It is, therefore, critical to begin thinking seriously about ways to reduce this influx into the atmosphere. Using carbon dioxide from fossil fuel combustion as a feedstock for the growth, photosynthetic microorganisms can provide a large sink for carbon assimilation as well as a feedstock for the production of significant levels of biofuels. Combining microalgal farming with fossil fuel energy production has great potential to diminish carbon dioxide releases into the atmosphere, as well as contribute to the production of biofuels (e.g., biodiesel, renewable diesel and gasoline and jet fuel) as well as valuable co-products such as animal feeds and green chemicals. CO2 capture may be a regulatory requirement in future new coal or natural gas power plants and will almost certainly become an opportunity for commerce, the results of such studies may provide industries in the US and Canada with both regulatory relief and business opportunities as well as the ability to meet environmental and regulatory requirements, and to produce large volumes of fuels and co-products

Gasoline Biodesulfurization DE-FC07-97ID13570 FINAL REPORT

Nine strains were identified to grow with gasoline as sole sulfur source. Two different genes were cloned from Gordonia terrae KGB1 and tested for the ability to support gasoline BDS. The first of these, fmoA, was cloned by screening a KGB1 gene library for the ability to convert indole to indigo (a sulfur-regulated capability in KGB1). The fmoA gene was overexpressed in a gasoline tolerant strain of Pseudomonas putida PpG1 and the recombinant strain was shown to convert thiophene to a dimer of thiophene sulfoxide at rates nearly two orders of magnitude higher than KGB1 could catalyze the reaction. Despite this high activity the recombinant PpG1 was unable to demonstrate any activity against gasoline either in shake flask or in bench-scale gasoline BDS bioreactor. A second gene (toeA) was cloned from KGB1 and shown to support growth of Rhodococcus erythropolis JB55 on gasoline. The toeA gene was also identified in another gasoline strain T. wratislaviensis EMT4, and was identified as a homolog of dszA from R. erythropolis IGTS8. Expression of this gene in JB55 supported conversion of DBTO2 (the natural substrate for DszA) to HPBS, but activity against gasoline was low and BDS results were inconsistent. It appeared that activity was directed against C2- and C3-thiophenes. Efforts to increase gene expression by plasmid manipulation, by addition of flavin reductase genes, or by expression in PpG1 were unsuccessful. The DszC protein (DBT monooxygenase) from IGTS8 has very little activity against the sulfur compounds in gasoline, but a mutant enzyme with a substitution of phenylalanine for valine at position 261 was shown to have an altered substrate range. This alteration resulted in increased activity against gasoline, with activity towards mainly C3- and C4-thiophenes and benzothiophene. A mutant library of dszB was constructed by RACHITT (W. C. Coco et al., DNA shuffling method for generating highly recombined genes and evolved enzymes. 2001. Nature Biotech. 19:354-359) method of in vitro recombination. Methods for analysis were developed and a preliminary analysis of the library was performed. A preliminary gasoline process design was constructed and process economics were determined based upon assumptions made from experimental results. The projected cost of gasoline BDS was determined to be competitive with current competing technologies

Variedades de la experiencia de sí mismo: una fenomenología comparativa de la melancolía, la manía y la esquizofrenia. Parte I

Este trabajo ofrece un estudio crítico de algunos trastornos de la experiencia de sí mismo [self experience], sutiles y a menudo pasados por alto, que pueden encontrarse en la esquizofrenia, la melancolía y la manía. El objetivo es mejorar la comprensión de las similitudes y las diferencias entre estos desórdenes. Aquí presentamos estudios clásicos y contemporáneos, en su mayoría de la tradición fenomenológica, que ilustramos con reportes de pacientes. Se consideran cambios experienciales en cinco dominios del “sí mismo” [selfhood] (siguiendo a Parnas et al., 2005): cognición, auto-conciencia, experiencias corporales, demarcación/transitivismo, y reorientación existencial. Vamos a discutir: I, las principales diferencias entre la esquizofrenia y los desordenes afectivos que involucran la experiencia propia; II, experiencias en las cuales estas condiciones, a pesar de las diferencias principales, se parecen entre sí; y III, sugerencias sobre cómo estas experiencias pueden, sin embargo, diferenciarse en un plano fenomenológico más sutil. Mientras que los pacientes afectivos pueden pasar por cambios significativos en su experiencia propia, su sentido subyacente de una individualidad mínima o básica (“ipseidad”) se mantiene intacto. En la esquizofrenia hay un trastorno del sí mismo [self] básico, y esto nos puede ayudar a dar cuenta de muchos de los trastornos característicos de este desorden

Examination of Triacylglycerol Biosynthetic Pathways via De Novo Transcriptomic and Proteomic Analyses in an Unsequenced Microalga

Biofuels derived from algal lipids represent an opportunity to dramatically impact the global energy demand for transportation fuels. Systems biology analyses of oleaginous algae could greatly accelerate the commercialization of algal-derived biofuels by elucidating the key components involved in lipid productivity and leading to the initiation of hypothesis-driven strain-improvement strategies. However, higher-level systems biology analyses, such as transcriptomics and proteomics, are highly dependent upon available genomic sequence data, and the lack of these data has hindered the pursuit of such analyses for many oleaginous microalgae. In order to examine the triacylglycerol biosynthetic pathway in the unsequenced oleaginous microalga, Chlorella vulgaris, we have established a strategy with which to bypass the necessity for genomic sequence information by using the transcriptome as a guide. Our results indicate an upregulation of both fatty acid and triacylglycerol biosynthetic machinery under oil-accumulating conditions, and demonstrate the utility of a de novo assembled transcriptome as a search model for proteomic analysis of an unsequenced microalga
