The Use of Social Media as a Tool for Learning: Perspectives of Students in the Faculty of Education at Kuwait University

The purpose of this study is to explore the use of social media by students in the Faculty of Education, University of Kuwait. The study was conducted within the context of the socio-cultural characteristics of Kuwait, and was underpinned by Alsaied ’ s (2017) Social Media - Learning Performance model, designed for female Arab students. A volunteer sample of 35 Kuwaiti undergraduate students (88.6% female) was interviewed. Students reported frequently using social media informally for socialization and entertainment, but less frequently as a formal educational tool. Most of the students perceived that social media facilitated interaction with peers, interaction with faculty, engagement, and collaborative learning. However, technical difficulties, and certain negative attitudes towards women using social media, were identified. We recommend that Kuwait University needs to harness the full benefits of social media for teaching and learning and to formulate official guidelines to control the use of social media by all faculty members and students.
Effects of different poultry waste manure rates and irrigation intervals on okra (Abclmoschus esculenfus L.) growth and yield performance

The use of organic addition has been found to be an environmentally beneficial method for enhancing quality of crops with good soil quality. Similarly, selection of suitable irrigation period is an important factor for optimum crop production. A study was conducted to evaluate the effects of chicken manure and irrigation interval on the development and production of okra in a greenhouse. The poultry manure was applied to 5 kg soil at three different rates, namely: 20 t ha-1 (T1), 40 t ha-1 (T2), and 60 t ha-1 (T3), and the fourth group without poultry manure treatment were set up as the control. Four levels of irrigation intervals (3, 6, 9 and 12 days) were selected for the study. Plant height, number of leaves, leaf area (cm2), and stem diameter were all assessed as growth metrics. Leaf fresh weight, leaf dry weight, shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, and total plant dry weight were the yield characteristics that were measured. The findings indicated that increasing poultry manure rates enhanced the examined growth and yield parameters, but increasing irrigation intervals decreased the studied growth and yield characteristics of Abelmoschus esculentus. The interplay between chicken manure and irrigation intervals, on the other hand, had no significant effect on leaf area and stem diameter. Finally, the application of 60 t ha-1 poultry manure and a three-day watering interval boosted the development of Abelmoschus esculentus. Keywords: Abelmoschus esculentus, irrigation, okra, poultry manure, yield
Theoretical Analysis on Thermoelectric Power Generation with Rectangular-Fin Elements and Its Applicability in Micro Systems

A thermoelectric module, which consists of rectangular-fin elements and has a simple structure suitable for micro fabrication, was newly proposed for a micro- to milli-scale thermoelectric power generator. A unit model was introduced to examine the basic characteristics of thermoelectric power generation with rectangular-fin elements. Theoretical descriptions of the power density and conversion efficiency were given by solving one-dimensional heat and current flows inside the elements. Then, it was found that there exist optimum aspect ratios of the elements to achieve maximum power density and conversion efficiency. Power density becomes larger if the module is downsized with a similarity in shape, while conversion efficiency remains constant, i.e., smaller devices show better performance. Finally, comparative analysis with a standard pi-type module was conducted to emphasize the superiority of the proposed module in micro systems, when convective heat transfer resistance is taken into account. © 2006 Wiley Periodicals, Inc.

Numerical Design Studies on Internal Flow Characteristics of LOX/CH4 Swirl Injector

Numerical design study of the central post of a full-scale liquid oxygen and liquid methane (LOXLCH4) swirl coaxial injector element has been carried out utilizing the unsteady ReynoldsAveraged Navier-Stokes (URANS) approach. The scope of the present study involves water cold flow with atmospheric chamber pressure corresponding to a parallel experimental investigation [6]. To characterize the internal two phase flow of the nozzle, the Eulerian Volume of Fluid (VOF) method was used to capture the sharp liquid-gas interface encountered in liquid swirl injector involving air cores. The goal of the numerical simulation is to predict the liquid film thickness and spray cone angle at the injector exit to be used for subsequent atomization/spray modeling studies. The numerical results are compared with the parallel experimental effort [6]. The 2-D axisymmetric numerical computations performed on the LOX inner swirl injector indicated that the accurate prediction of the liquid film thickness is essential to evaluating the swirling sheet’s free cone spray angle at the exit face of the nozzle.
Theta- and gamma-band oscillatory uncoupling in the macaque hippocampus

Nested hippocampal oscillations in the rodent give rise to temporal dynamics that may underlie learning, memory, and decision making. Although theta/gamma coupling in rodent CA1 occurs during exploration, in contrast to sharp-wave ripples that emerge in quiescence, it is less clear that these oscillatory regimes extend to primates. We, therefore, sought to identify correspondences in frequency bands, nesting, and behavioral coupling taken from the macaque hippocampus. We found that, in contrast to rodent oscillations, theta and gamma frequency bands in macaque CA1 were segregated by behavioral states. Beta2/gamma (15-70 Hz) had greater power during visual search while the theta band (3-10 Hz; peak ∼8 Hz) dominated during quiescence. Moreover, theta band amplitude was strongest when beta2/slow gamma (20-35 Hz) amplitude was weakest, occurring instead concomitant with higher frequencies (60-150 Hz). Spike-field coherence was most frequently seen in these three bands, (3-10 Hz, 20-35 Hz, and 60-150 Hz); however, the theta-band coherence was largely due to spurious coupling during sharp-wave ripples. Accordingly, no intrinsic theta spiking rhythmicity was apparent. These results support a role for beta2/slow gamma modulation in CA1 during active exploration in the primate that is decoupled from theta oscillations. The apparent difference to the rodent oscillatory canon calls for a shift in focus of frequency when considering the primate hippocampus.
Impaired Endogenous Neurosteroid Signaling Contributes to Behavioral Deficits Associated With Chronic Stress

Chronic stress is a major risk factor for psychiatric illnesses, including depression; however, the pathophysiological mechanisms whereby stress leads to mood disorders remain unclear. The recent FDA approval of antidepressants with novel mechanisms of action, like Zulresso®, a synthetic neuroactive steroid analog with molecular pharmacology similar to allopregnanolone, has spurred interest in new therapeutic targets and, potentially, novel pathophysiological mechanisms for depression. Allopregnanolone acts as a positive allosteric modulator of GABAA receptors (GABAARS), acting preferentially at δ subunit-containing receptors (δ-GABAARS). Accumulating clinical and preclinical evidence supports the antidepressant effects of exogenous administration of allopregnanolone and allopregnanolone analogs; however, the role of endogenous neurosteroids in the pathophysiology of depression remains unknown. Here, we examine whether altered neurosteroid signaling may contribute to behavioral deficits following chronic unpredictable stress (CUS) in mice. We first identified reductions in expression of δ-GABAARs, the predominant site of action of 5a-reduced neuroactive steroids, following CUS. Additionally, utilizing LC-MS/MS we discovered a decrease in levels of allopregnanolone in the BLA, but not plasma of mice following CUS, an indication of impaired neurosteroid synthesis. CRISPR knockdown the rate-limiting enzymes involved in allopregnanolone synthesis, 5α-reductase type 1 and 2, in the BLA mimicked the behavioral deficits associated with CUS in mice. Furthermore, overexpression expression of 5α-reductase type 1 and 2 in the BLA improved behavioral outcomes. Collectively, this suggests chronic stress impairs endogenous neurosteroid signaling in the BLA which is sufficient to induce behavioral deficits similar to those observed following CUS. Further, these studies suggest that the therapeutic efficacy of allopregnanolone-based treatments may be due to their ability to directly target the underlying pathophysiology of mood disorders. Therefore, targeting endogenous neurosteroidogenesis may offer a novel therapeutic strategy for the treatment of mood disorders.
Formulation of zwitter-ionic terpolymeric hydrogels and their comprehensive rheological investigation

Abstract With the rapid enhancement in pharmaceutics, cosmetics, medical applications, and water contamination, the demand of hydrogels with varying properties is increasing day by day. Hydrogels with keen properties like pH sensitive, thermosensitive, biocompatibility, visco-elasticity, mechanical rigidity, and resistive to exterior stress are of great interest. In order to attain such properties for above mentioned applications, a zwitter ionic hydrogel was synthesized having flexible nature, pH sensitive and is tested using rheometer. Rheological properties are elucidated using frequency sweep and flow curve analysis. The fluidity index lower than unity indicates the non-Newtonian shear thinning behavior. The lower value of shear thinning makes it a feasible candidate to be used in paints and cosmetics industries like nail polish, lotions etc. Values for consistency index increased with rising temperature and increasing amount of AMPS. The increase in consistency coefficient and yield stress with increasing temperature from 25 to 35 ̊C indicates the strengthing of hydrogels which will facilitates jellification of drug delivery system on skin. Modified Bingham model was found the best fit to our rheological data. The thermodynamic data obtained revealed higher activation energy for ZHG-02 with greater concentration of AMPS than ZHG-01 with lower amount of AMPS. Graphical Abstract

Totally Ultrasound-Guided Minimally Invasive Percutaneous Nephrolithotomy in Children: Is It Safe?

Objective: The objective of the study was to assess the outcome and feasibility of ultrasonography (US)-guided minimally invasive percutaneous nephrolithotomy (mini-PCNL) in children. Materials and Methods: Twenty-five children with upper urinary tract stones who had undergone US-guided mini-PCNL from June 2017 to June 2020 were enrolled in this study. Patients' demographic information and post-treatment results were retrospectively gathered and analysed. Pyelocaliceal system was punctured in prone position using US guidance, and the tract was dilated using single-shot dilation technique. All steps of renal access were done using only US. Mini-PCNL in all cases was done by using 15 Fr rigid nephroscope. Stones were fragmented with a pneumatic lithotripter and evacuated. Results: The patients' mean age was 6.30 ± 3.25 years (range: 1.5–15). The mean stone size was 16.04 ± 3.93 mm (range: 10–30). The mean access time to the stone was 1.50 ± 0.62 min (range: 1–4). The mean operation time was 94.66 ± 3.05 min (range: 90–100 min). The final stone-free rate was 96%. Post-operation fever occurred in 4 (16%) patients who were treated successfully with an antibiotic. No major complications occurred. Conclusions: We recommend US-guided mini-PCNL as a harmless alternative treatment option, in children with renal calculi due to its excellent outcomes and little complications.

Also, the results revealed that student’s interest and perception significantly predicted students’ achievement in mathematics. Again, a positive, moderate and significant relationship was recorded between students’ interest and achievements in mathematics. Furthermore, there was a positive weak correlation between students’ perception and achievement in mathematics which is also significant. Finally, weak positive significant correlation was recorded for the relationship between students’ perception and interest towards mathematics.
Cell type–specific interpretation of noncoding variants using deep learning–based methods

Interpretation of non-coding genomic variants is one of the most important challenges in human genetics. Machine learning methods have emerged recently as a powerful tool to solve this problem. State-of-the-art approaches allow prediction of transcriptional and epigenetic effects caused by non-coding mutations. However, these approaches require specific experimental data for training and can not generalize across cell types where required features were not experimentally measured. We show here that available epigenetic characteristics of human cell types are extremely sparse, limiting those approaches that rely on specific epigenetic input. We propose a new neural network architecture, DeepCT, which can learn complex interconnections of epigenetic features and infer unmeasured data from any available input. Furthermore, we show that DeepCT can learn cell type-specific properties, build biologically meaningful vector representations of cell types and utilize these representations to generate cell type-specific predictions of the effects of non-coding variations in the human genome.
Hemp Shive-Based Bio-Composites Bounded by Potato Starch Binder: The Roles of Aggregate Particle Size and Aspect Ratio

According to European regulations, the construction industry supports and strives to save non-renewable natural resources, increases the share of reusable resources in production and attempts to use renewable natural resources as much as possible by creating alternative building materials, such as bio-composites. Various building materials containing hemp shives (HS) are relatively popular and are often used in practice. The properties of these materials vary widely due to the usage of significantly different binders and because the parameters of the HS can significantly affect the properties of the bio-composite. Potato starch (PS), the properties of which have not been studied extensively in the past, was used as a binder in this study. Depending on the type of manufacturing process and technology employed for hemp fibre production, the HS particle shape and size can vary widely, which leads to the following statement: the properties of bio-composites produced by using the same method, but with different HS, may differ significantly. In order to investigate the effects of HS on the properties of bio-composites, including the hydro-thermal properties, an in-depth study was conducted to examine the structure, the physical properties and the particle size of HS. It was discovered that in order to obtain a material of higher compressive strength, the HS with smaller dimensions should be used; however, if enhanced thermal properties are required, the HS with longer particles should be used.

The numerical results are compared to measurements performed during the experimental campaign.
Length of life of equipment in French manufacturing industries

Times series of capital and investment for indi vidual manufacturing firms based on balance sheet data serve to estimate the average lifetime and the lifetime distribution of equipment. Four models of lifetime distribution are considered : fixed lifetime, exponential, * lognormal and Weibull. The data are treated in three different ways, with and without aggregation or the sim plifying assumption of identical lifetime distri bution for each firm within the same manu facturing sector. The simplest model, fixed lifetime of capital equipment, is generally appropriate. Even taking into account various possible biases, the results indicate average ser vice lives ranging between 16 to 21 years for all sectors and periods. * Margaret Atkinson, Adelaide University and INSEE, Jacques Mairess? , Unit? de Recherche INSEE.
