Language use and maintenance among the Moroccan minority in Britain

The goal of this study is to investigate language use among a relatively young immigrant community in Britain with a view to finding out what role English plays in their lives, whether they still use their languages of origin, and what are the reasons for their particular language behaviour. Language use and maintenance in an immigrant minority setting is an important area of investigation if one is to understand some of the factors involved in the community's integration process, or the lack of it, in general, and to appreciate the role of language for integration in particular. Minority communities adopt a number of linguistic strategies for communication among themselves and their wider community. In most cases, these linguistic strategies are dictated by both the social and linguistic environment the immigrant minority finds itself living in. The thesis first looks at the sociolinguistic situation of Morocco in order to establish the linguistic background of this community. It then considers the British Moroccans from a socio-economic perspective with a view to identifying factors that may influence language shift behaviour. The empirical part of the thesis is concerned with establishing linguistic as well as non-linguistic determinants of language maintenance such as those that influence language choice, code-switching, attitudes and use of language-specific media. The study has two main hypotheses: first, the Moroccan community in Britain is undergoing a generational language shift, and second, typical Moroccan sociolinguistic patterns are reflected in the language use of Moroccan speakers in Britain as well. While the former hypothesis has, on the whole, proved correct, the latter did not hold true.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

A comparative study of the lipid panel levels at different duration time and temperature storage

Background: the stability of serum specimen during time storage is importance in clinical and medical science researches in addition of diagnosis. Lipids are organic molecules that classified into 8 classes: fatty acids, phospholipids, glycerolipids, saccharolipids, polyketides, prenol lipids, sterol, and sphingolipids. Lipid analysis (cholesterol, triglyceride, high density lipoprotein, low density lipoprotein, very low-density lipoprotein) is a vital tool for diagnosis of numerous disease such as cardiovascular disease. follow-up the lipid profile progression is essential of numerous diseases. Methods: a 72 apparently healthy individual were participated in current study the serum sample was taken after 12-14 hours of fasting. The serum cholesterol, triglyceride, high density cholesterol, low density cholesterol, and very low-density cholesterol were determined. Results: there are no significant value found in all groups when compared to control except triglyceride that was significant after 24 hours of freezing.Comment: 7 page, 1 table, 1 figur

Multigeneic QTL: The Laccase Encoded within the Soybean Rfs2/rhg1 Locus Inferred to Underlie Part of the Dual Resistance to Cyst Nematode and Sudden Death Syndrome

Multigeneic QTL present significant problems to analysis. Resistance to soybean (Glycine max (L) Merr.) sudden death syndrome (SDS) caused by Fusarium virguliforme was partly underlain by QRfs2 that was clustered with, or pleiotropic to, the multigeneic rhg1 locus providing resistance to soybean cyst nematode (SCN; Heterodera glycines ). A group of five genes were found between the two markers that delimited the Rfs2/rhg1 locus. One of the five genes was predicted to encode an unusual diphenol oxidase (laccase; EC 1.10.3.2). The aim of this study was to characterize this member of the soybean laccase gene-family and explore its involvement in SDS resistance. A genomic clone and a full length cDNA was isolated from resistant cultivar \u27Forrest\u27 that were different among susceptible cultivars \u27Asgrow 3244\u27 and \u27Williams 82\u27 at four residues R/H168, I/M271, R/H330, E/K470. Additional differences were found in six of the seven introns and the promoter region. Transcript abundance (TA) among genotypes that varied for resistance to SDS or SCN did not differ significantly. Therefore the protein activity was inferred to underlie resistance. Protein expressed in yeast pYES2/NTB had weak enzyme activity with common substrates but good activity with root phenolics. The Forrest isoform may underlie both QRfs 2 and rhg

Réalisation de transistors bipolaires à double hétérojonction (DHBT) GaAlAs/GaAs pour circuits intégrés I2L

Dans cet article, nous montrons l'intérêt du transistor bipolaire à double hétérojonction (DHBT) pour la filière logique rapide I2L (logique à injection). En effet l'interchangeabilité entre l'émetteur et le collecteur et la liberté de conception résultant de l'utilisation de deux hétérojonctions donnent aux DHBT un grand intérêt dans le domaine des circuits intégrés rapides à grande intégration tels que la logique à injection I2L. L'accent est mis sur le comportement en régime statique de dispositifs d'étude, réalisés par les techniques d'épitaxie par jets moléculaires et d'implantation ionique de magnésium. Les résultats les plus intéressants sont l'obtention de dispositifs symétriques présentant un gain en courant en régime de fonctionnement inverse de 40 pour un gain de 280 en régime normal et de tensions de saturation très faibles de l'ordre de 3 mV

Optimizing expression and purification of an ATP-binding gene gsiA from Escherichia coli k-12 by using GFP fusion

The cloning, expression and purification of the glutathione (sulfur) import system ATP-binding protein (gsiA) was carried out. The coding sequence of Escherichia coli gsiA, which encodes the ATP-binding protein of a glutathione importer, was amplified by PCR, and then inserted into a prokaryotic expression vector pWaldo-GFPe harboring green fluorescent protein (GFP) reporter gene. The resulting recombinant plasmid pWaldo-GFP-GsiA was transformed into various E. coli strains, and expression conditions were optimized. The effect of five E. coli expression strains on the production of the recombinant gsiA protein was evaluated. E. coli BL21 (DE3) was found to be the most productive strain for GsiA-GFP fusion-protein expression, most of which was insoluble fraction. However, results from in-gel and Western blot analysis suggested that expression of recombinant GsiA in Rosetta (DE3) provides an efficient source in soluble form. By using GFP as reporter, the most suitable host strain was conveniently obtained, whereby optimizing conditions for overexpression and purification of the proteins for further functional and structural studies, became, not only less laborious, but also time-saving

Patterns and Mechanisms of Ancestral Histone Protein Inheritance in Budding Yeast

Tracking of ancestral histone proteins over multiple generations of genome replication in yeast reveals that old histones move along genes from 3′ toward 5′ over time, and that maternal histones move up to around 400 bp during genomic replication
