The movement of individual hydrocarbons in a high pressure displacement process
No full textIn this investigation the effects of sand grain size, injection rate, and type of gas injected upon the recovery of the intermediate (C₂-C₆) hydrocarbons by high pressure gas injection were studied by making a series of displacement tests on a sand-pack 20ft. long and one inch in diameter. In each of the displacement experiments an attempt was made to maintain a constant flow rate at a constant injection pressure. All of the reported data were obtained from experiments made with one mixture of intermediate hydrocarbons. Three different sands were used. The finest had a permeability of 2.1 Darcys while the coarsest had a permeability of 13.7 Darcys. Injection rates of 1, 2, and 3 ml/min with the gases methane, nitrogen and flue gas were used. During each experiment, samples of the produced fluid were analyzed for each component. In spite of constant concentrations before the breakthrough time, separation of components was noticed after that time. The concentrations of the produced hydrocarbons after breakthrough formed profiles with peaks in the same order as the volatility of the hydrocarbons. ..
The Egyptian Military in Popular Culture:Context and Critique
No full textThis book examines a key question through the lens of popular culture: Why did the Egyptian people opt to elect in June 2014 a new president (Abdel Fattah al-Sisi), who hails from the military establishment, after toppling a previous military dictator (Hosni Mubarak) with the breakout of the 25 January 2011 Revolution? In order to dissect this question, the author considers the complexity of the relationship between the Egyptian people and their national army, and how popular cultural products play a pivotal role in reinforcing or subverting this relationship. The author takes the reader on a ‘journey’ through crucial historical and political events in Egypt whilst focusing on multi-layered representations of the ‘military figure’ (the military leader, the heroic soldier, the freedom fighter, the conscript, the martyred soldier, and the Intelligence officer) in a wide range of popular works in literature, film, song, TV drama series, and graffiti art. Mostafa argues that the realm of popular culture in Egypt serves as the ‘blood veins’ which feed the nation’s perception of its Armed Forces

Although Lactococcus garvieae was historically considered the sole causative agent of piscine lactococcosis, recent studies have identified L. petauri and L. formosensis as additional, highly pathogenic species. In this study, we developed a novel TaqMan-based multiplex qPCR assay for the simultaneous detection and differentiation of L. garvieae, L. petauri and L. formosensis, following a pangenome analysis of the publicly available genomes of these bacterial species. The assay demonstrated high sensitivity and specificity across 156 bacterial isolates obtained from various cultured fish species and geographical locations between 2008 and 2024, as well as against a panel of non-target bacteria. It also successfully detected target pathogens in 146 field tissue samples, including tissues preserved in 70% ethanol, formalin-fixed paraffin-embedded (FFPE) tissues and tissues fixed on FTA cards. Compared to classical bacteriology, the multiplex qPCR assay yielded higher detection rates and enabled precise identification of the causative species of piscine lactococcosis. Overall, the multiplex qPCR assay developed in this study provides a reliable, rapid, highly sensitive and species-specific molecular approach for diagnosing piscine lactococcosis, contributing to better surveillance and management of the disease in aquaculture.Bursa Uludag UniversityDepto. de Sanidad AnimalFac. de VeterinariaTRUEpu
Chromosome-level genome assembly of Tritrichomonas foetus, the causative agent of Bovine Trichomonosis.
No full textAbdel-Glil MY, Solle J, Wibberg D, Neubauer H, Sprague LD. Chromosome-level genome assembly of Tritrichomonas foetus, the causative agent of Bovine Trichomonosis. Scientific Data . 2024;11(1): 1030 .Tritrichomonas foetus is a parasitic protist responsible for bovine trichomonosis, a reproductive disease associated with significant economic burden to the livestock industry throughout the world. Here, we present a chromosome-level reference genome of T. foetus -KV-1 (ATCC 30924) using short-read (Illumina Miseq), long-read (Oxford Nanopore) and chromatin-linked (Hi-C) sequencing. This is the first chromosome-level genome of a parasitic protist of the order Tritrichomonadida and the second within the Parabasalia lineage, after Trichomonas vaginalis, the human-associated causative agent of the sexually transmitted infection in humans. Our constructed genome is 148Mb in size, with a N50 length of the scaffolds of 22.9Mb. The contigs are anchored in five super-scaffolds, corresponding to the expected five chromosomes of the species and covering 78% of the genome assembly. We predict 41,341 protein-coding genes, of which 95.10% have been functionally annotated. This high-quality genome assembly serves as a valuable reference genome for T. foetus to support future studies in functional genomics, genetic conservation and taxonomy. © 2024. The Author(s)
Migration of leachate solutin through clay soil
No full textThe problem of domestic solid wastes buried in landfill sites is viewed from the aspect of leachate contamination and migration in the substrate. Generally, this occurs through the penetration of the contaminant into the liner material. This study assesses the efficiency of natural clay barriers as an expedient economic lining material.Various chemical constituents of the landfill leachate of an actual waste containment site at Lachenaie (35 km east of Montreal) were determined from samples collected from specially designed basins.In companion laboratory tests, these leachate samples were permeated through laboratory columns that contained the natural clay compacted at the optimum water content. The columns were constructed so as to permit simulation of slow, saturated, anaerobic flow of leachate through the clay lining surrounding the landfill and leachate basins. Leachates were permeated through the soil columns for periods of four to five months, during which effluents were collected periodically and analyzed for different chemical species and physical parameters. These chemical analyses measured changes in the concentration of: (a) cations (Na, K, Ca, and Mg), (b) anions (Cl, HCO, and CO), (c) total organic carbon (TOC), and (d) heavy metals (Fe, Zn, Pb, and Cu). The physical parameters measured included: (a) pH, and (b) specific conductivity.Subsequent to the leaching tests, the column contents were cut into six sections and analyzed to determine the distribution profiles of the adsorbed and retained contaminants at various time durations.Predictions, using a dispersion-convection model for concentration profile development for either adsorbed or retained contaminants, were compared with the experimentally determined profiles (both in leaching columns and landfill laboratory model).Another set of experiments was also conducted to evaluate the effect of some organic fluids on the geotechnical properties of different clay soils (natural clay and two reference clay soils: illite and kaolinite).The results from this study have demonstrated that the natural clay soil can be used to adequately contain the different contaminant species usually present in the leachate solutions. Furthermore, the data suggested that under favourable soil conditions, landfill leachates containing low levels of trace metals will not pose a substantial contamination threat to the subsurface environment, provided that a proper thickness of barrier is used.

No full textOn Bayesian Identification of Autoregressive Processes
No full textThe main objective of the current study is to handle the identification problem of autoregressive processes from the Bayesian point of view. Two Bayesian identification approaches are considered. They are referred to as the direct and the indirect approaches. The two approaches are employed to solve the Bayesian identification problem of autoregressive processes using three well known priors. These priors are the G prior, the Natural-Conjugate prior and Jeffrey's prior. The theoretical derivations related to the two Bayesian identification approaches are conducted using the above mentioned priors. Moreover, the performance of the two techniques, using each of the three priors, is investigated via comprehensive simulation studies. Simulation results show that the two techniques are adequate to solve the identification problem of autoregressive processes. The increase in the time series length leads to better performance for each technique. The use of different priors doesn't affect the previous results
