A ROTATIONAL ANALYSIS OF THE SYSTEM OF InCl
No full textAuthor Institution: Department of Chemistry, The Ohio State University ColumbusThe absorption spectrum of the system of InCl has been recorded in the region 2650 -- 2800 \AA. Our spectrum is in good agreement with that reported by Froslie and except that our resolution is appreciably higher. The improved resolution in the present study along with the availability of precise microwave for the ground state permits us to obtain significantly improved constants for the level of the state. As has been previously noted, levels with become progressively diffuse indicating predissociation. Predissociation in bands involving is indicated by increasing line width with increasing J. H.M.

Questioning the Borders of Contemporary US Fiction: H.M. Naqvi’s Home Boy, 9/11 and the American Novel
No full textThis essay investigates the margins of XXI century American novel in the light of the increasingly deterritorialized status of US culture and literature – a literature whose borders need to be reconfigured not only in terms of reception, but of creation as well. In particular, the essay focuses on the Pakistani-born author H. M. Naqvi and his first novel, Home Boy (2009) – part immigrant narrative, part Bildungsroman, part 9/11 novel. Rooting Home Boy deep in the American grain and at the same time investigating the construction of Otherness through the protagonist’s “inoutsider” status and perspective, Naqvi explores the potential and the limits of what can be defined as “performative Americaness”, defined not by genealogic or geographical belonging, but by cultural and literary affiliations in the politically and socially unstable scenario of the post-national world
Population differences in immune responses to Bacille Calmette-Guérin vaccination in infancy.
No full textBacille Calmette-Guérin (BCG) vaccination induces a marked increase in the interferon (IFN)-gamma response to Mycobacterium tuberculosis purified protein derivative (Mtb PPD) in UK adolescents, but not in Malawian adolescents. We hypothesized that Mtb PPD-induced IFN-gamma after BCG vaccination would be similar in infants from these 2 countries. Infants were vaccinated with BCG during the first 3-13 weeks of life. Three months after BCG vaccination, 51 (100%) of 51 UK infants had an IFN-gamma response to Mtb PPD, compared to 41 (53%) of 78 of Malawian infants, in whom responses varied according to their season of birth. We conclude that population differences in immune responses after BCG vaccination are observed among infants, as well as among young adults
An analysis of numerical model applications to river hydrodynamics
No full textDouble Master of Science in Hydraulic Engineering (Civil Engineering and Geosciences) and Applied Mathematics (Electrical Engineering, Mathematics and Computer Science) - It is of importance to know how the water is behaving in rivers due to the dangers, such as flooding and eroding of land, it can bring with it. Present day we are still reshaping rivers, building structures in rivers or adjusting them, which results in changes in the hydrodynamics and morphology. In order to obtain more insight in the consequences of these adjustments, it is convenient to use a numerical model to simulate the river hydrodynamics. For the last decades numerical models have been developed that are able to simulate hydrodynamics. Currently, new software packages are proposed that are more efficient in predicting this. Two of these new software packages are D-Flow Flexible Mesh (FM) and 3Di. Whereas the first is especially designed to model the hydrodynamics of rivers and other flows such as in estuaries, the latter is mostly used for the simulation of flooding of land (for example due to dike breaches). The usage of numerical model applications results usually in many choices that have to be made. Based on these choice there are considerations that need to be taken into account. Both these choices and considerations will have influence on the river hydrodynamics. With two new packages available that can simulate hydrodynamics, the choices and possibilities for each package should be clear. When multiple numerical model applications are considered the similarities and differences should be known. The aim of this thesis is to indicate which considerations and consequences for simulations, that follow from the choices in numerical model applications, are important for the suitability of results given a specific problem.Civil Engineering and GeosciencesHydraulic Engineering3Di en D-Flow Flexible Mes

Hundreds of variants clustered in genomic loci and biological pathways affect human height
No full textMost common human traits and diseases have a polygenic pattern of inheritance: DNA sequence variants at many genetic loci influence the phenotype. Genome-wide association (GWA) studies have identified more than 600 variants associated with human traits(1), but these typically explain small fractions of phenotypic variation, raising questions about the use of further studies. Here, using 183,727 individuals, we show that hundreds of genetic variants, in at least 180 loci, influence adult height, a highly heritable and classic polygenic trait(2,3). The large number of loci reveals patterns with important implications for genetic studies of common human diseases and traits. First, the 180 loci are not random, but instead are enriched for genes that are connected in biological pathways (P = 0.016) and that underlie skeletal growth defects (P<0.001). Second, the likely causal gene is often located near the most strongly associated variant: in 13 of 21 loci containing a known skeletal growth gene, that gene was closest to the associated variant. Third, at least 19 loci have multiple independently associated variants, suggesting that allelic heterogeneity is a frequent feature of polygenic traits, that comprehensive explorations of already-discovered loci should discover additional variants and that an appreciable fraction of associated loci may have been identified. Fourth, associated variants are enriched for likely functional effects on genes, being over-represented among variants that alter amino-acid structure of proteins and expression levels of nearby genes. Our data explain approximately 10% of the phenotypic variation in height, and we estimate that unidentified common variants of similar effect sizes would increase this figure to approximately 16% of phenotypic variation (approximately 20% of heritable variation). Although additional approaches are needed to dissect the genetic architecture of polygenic human traits fully, our findings indicate that GWA studies can identify large numbers of loci that implicate biologically relevant genes and pathways

Practical approach for production of bacteria-based agent-contained light weight aggregates to make concrete self-healing
No full textA functional experimental concrete system has been developed in our lab, in which a two component bacteria-based healing agent contained in a protective reservoir is included in the concrete mixture. Incorporated bacteria have the potential to produce copious amounts of calcium carbonate based crystals from supplied mineral precursor compounds. Precipitates of the carbonate mineral seal and block occurring cracks. Particles of expanded clay, a type of light weight aggregate (LWA), were chosen as protective reservoir in which the bacteria and precursor compound are contained. Most effective method for intrusion of healing agent in LWA is by vacuum impregnation, a rather expensive process. In this work a more economically feasible in-situ approach is proposed, still gaining the required healing capacity. Prior to mixing LWA are pre-wetted with a warm liquid impregnation solution (80°C) carrying bacterial spores and mineral precursor compounds. This alternative production process is economical and practically more straightforward and functionally additionally beneficial as water-saturated LWA contribute to internal curing. Benefit of the novel approach is the reduced cost of healing agent production and improved practicality directly at a concrete plant, as commonly available equipment can be used. First tests indicate sufficient healing capacity remains after the wet mixing stage and internal drying by cement hydration.Structural EngineeringCivil Engineering and Geoscience
