Effect of silicon application on roselle (Hibiscus sabdariffa L.) grown in a Vertisol in Egypt
No full textRoselle (Hibiscus sabdariffa L.) is an important tropical and subtropical crop, because of its multi uses in the medicinal purposes as well as food industries. A plot experiment was conducted in a Vertisol in Egypt over two sequential seasons (2013 and 2014) to assess the effect of silicon (Si) fertilization on roselle growth and yield. Specific growth characteristics measured were: plant heights, branching, and leaves; biomass and calyces yield; and concentrations of anthocyanin, total soluble solids (TSS), carbohydrates, N, P, and K in the calyces. The experiment compared five rates of Si fertilization (0.00, 1.75, 3.50, 5.25, and 7.00 kg Si ha-1). One-third of each rate was applied as a foliar spray at 45, 60, and 75 days after sowing, respectively. Results showed an increase in plant height, number of branches and leaves to Si fertilization rates. Similarly, anthocyanin and TSS concentration increased with increasing Si rates. Anthocyanin concentration significantly increased by 16.3% as the applied Si rate increased from 0.00 to 5.25 kg Si ha-1. However, carbohydrate content was not affected by the applied Si rates. Nutrients (N, P, and K) concentrations, in the calyces extract, increased with increasing the applied Si rate. Biomass and calyces yield increased by 23 and 33%, respectively, as the applied Si rate increased from 0.00 to 5.25 kg Si ha-1. The highest values of all of the measured properties were observed under the Si rate of 5.25 kg Si ha-1, and the lowest values were obtained from the control treatment (0.00 kg Si ha-1).This article is published as Abdelkader, Mohammed A., Mostafa A.

L’année de Bacchus d’El Mostafa Bouignane entre devoir de la mémoire et exaltation de la vie
No full textThis study will discuss the approach to the structure and narrative composition of the novel entitled L\u27année de Bacchus by Mostafa Bouignane, published by Virgule Editions in 2020. This text adds to a series of stories of which Bouignane constructs a narrative universe to reveal the nature of man who, even submissive and reduced, remains capable of regaining his freedom and leading a peaceful life. Thus, our study will propose an analysis of the ideological and historical dimension of this text representative of the literary experience of the author, then at the end the questioning of his human and moral values
Experimental and Numerical Investigations of Salinity Gradient Energy Harvesting by Pressure Retarded Osmosis
No full textSalinity Gradient Energy (SGE) is the energy available from the difference in the salt concentration between two solutions such as seawater and river water. It is a promising source of renewable energy since it utilizes naturally occurring processes and does not release any emissions. Pressure retarded osmosis (PRO) is a practical membrane process developed to harvest SGE. Despite its great potential, power generation through PRO is not yet commercialized because of many challenges such as the low performance of the available membrane modules, pressure drop in flow channels, pressure effect of the high salinity solution, and varying temperature effect. This study investigates these challenges and develops a new membrane module design to enhance PRO performance for large-scale osmotic power plants. A novel spiral wound module design is proposed that reduces pressure drop and enhances power density (power generated per membrane area). The performance of the new design was compared with the commercially available design and was found to reduce the pressure drop by 35% resulting in an increase in the power density by 25% when using seawater and freshwater. Furthermore, a new approach is proposed for the calculation of the pressure drop in the spacer-filled channels by treating the channels as porous media and using Darcy-Forchheimer model. In this approach, a permeability coefficient of the spacer-filled channel is calculated from the spacer filament diameter and porosity. Pressure drop data calculated using this approach was in good agreement with the experimental data in the literature. Finally, numerical and experimental investigations into the effect of solutions temperature on PRO performance were carried out. The results showed an enhanced power density of up to 90% when increasing the solutions temperature from 10 to 35 °C. This was due to the change in membrane properties as the water permeability coefficient increased by 55 % and the salt permeability coefficient increased by 100%, while the membrane structure parameter decreased by 40%. The results presented in this thesis enhance our understanding of the challenges that are facing PRO commercialization and proposes a new membrane module design that improves the performance of large-scale osmotic power plant.Natural Sciences and Engineering Research Council of Canada2023-08-0

Description: A large worker from al-Ain was selected as holotype. The measurements are as follows: total length 8.40; head width 3.60; head length 4.20; scape length 3.84; funicular segment I 0.40; funicular segment II 0.23; petiole length 1.10; petiole width 0.72. Colour dark reddish brown. There are no exterior hairs on the scapes or hind tibia. The gaster, petiole and propodeum have dorsal hairs. Remarks: This species thought to correspond with C. desertorum has to be described as a new species. In fact it is one of the commonest Cataglyphis in southern Arabia. The main distinguishing feature compared with other dark Cataglyphis is the slender petiole, which has the anterior face more sloped than in other similar species such as C. niger (André, 1882) and C. savignyi (Dufour, 1862). Biology: Cataglyphus laylae nov. spec. does not appear to occur in open sandy desert and is most abundant in disturbed habitats such as man-developed plantations and open cultivated fields. Distribution: This species was recorded by Collingwood (1985) as C. desertorum from Saudi Arabia and Oman and as Cataglyphis spec. by Collingwood & Agosti (1996). Etymology: The new species is named after a village settlement called “Layla”, just north of Riyadh (Saudi Arabia) in the area where the author (CAC) first encountered it in numbers in an Acacia plantation.Published as part of Cedric A.

Digital amplification for pathogen detection in bloodstream infections from whole blood
No full textSensitive and specific detection of bacteria is essential for control and treatment of bloodstream infections. Sepsis, a diagnostic challenge of blood stream infections, causes thousands of deaths each year. The gold standard for detection and identification of microorganisms is blood culture, which can take up to 5 days to yield a diagnosis or a negative result. Molecular diagnostic methods and nucleic acid assays developed to detect pathogens often require enrichment through blood culture prior to DNA extraction. Nonetheless, state of the art diagnostic tests that detect pathogens directly from blood are available with limitations. Increased amount of sample processing and purification is required before detection of pathogens and turnaround time to results can be up to 8 hours. Moreover, the sensitivity and specificity of such assays are broad in range. Thus, there is a need for a rapid detection method that can identify pathogens from whole blood within 1-2 hours, with minimal sample processing and high sensitivity and specificity.
In this work, we demonstrate detection of bacterial pathogens from whole blood through loop mediated isothermal amplification without the steps of DNA purification and extraction. Whole blood with pathogens is dried to tubes, creating separated phases of the cellular debris of blood from the amplification reaction and allowing for separation of background human DNA from target DNA as well as better detection of amplicons that are not masked by red blood cells. We show that this method is robust, having a detection limit of 1 cfu of pathogens in 4uL of whole blood. In preparation of processing higher blood volumes in a digital amplification method, we also show characterization experiments and preliminary results of amplification of pathogens from whole blood on chip.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-12-01The student, Ariana Mostafa, accepted the attached license on 2019-12-04 at 05:15.The student, Ariana Mostafa, submitted this Thesis for approval on 2019-12-04 at 05:29.This Thesis was approved for publication on 2019-12-05 at 09:04.DSpace SAF Submission Ingestion Package generated from Vireo submission #14686 on 2020-02-28 at 17:23:14Made available in DSpace on 2020-03-02T22:15:06Z (GMT).
