FACTORS AFFECTING AN INDIVIDUAL’S ADMISSION INTO SUBSTANCE ABUSE TREATMENT by

This study was looking at the factors that predicted an individual’s initial entrance into substance abuse treatment. More specifically, this study looked at the influence between an individual’s demographics, preferred drug of choice and number of Interim Groups attended and how these factors related to the individual’s motivation to follow through with substance abuse treatment. The participants in this study were individuals who were on local substance abuse treatment waiting lists. An analysis of the data was conducted using logistic regression. The statistical results indicated that demographics and preferred drug of choice were not predictive of an individual’s substance abuse treatment entry. Factors such as the number of Interim Groups attended and the individual’s motivation and readiness for substance abuse treatment, as measured by the SOCRATES, were found to be significant, although they offered little predictive value regarding subsequent substance abuse treatment attendance. Research and clinical implications of these findings were discussed.

‘Just notes’: Young musicians’ views on learning expressive performance

Expressiveness is an important aspect of an excellent music performance as it adds quality and interest to the playing and listening experience. Although several studies have investigated tertiary students’ learning of expressiveness, little is known about effective approaches for teaching children to perform expressively. In the present project 16 young musicians (aged 9-16, Pre-Grade 1 – Grade 8) took part in a video-stimulated recall interview after an experimental investigation which had featured methods for teaching and facilitating expressiveness. The interviews explored pupils’ views on that instruction, which included practice of difficult sections, scales practice, improvisation, and questions and dialogue regarding musical character. Participants who had been taught via dialogic teaching indicated that the questions relating to musical character and expressive tools had been helpful for their understanding of the ‘musicality’ of their pieces and thus for their learning of performance expression. The questions regarding musical character were seen as helpful, as this had facilitated pupils’ reflection on, and understanding of the interpretation, thus contributing to their learning of expressiveness. This demonstrates the importance of teachers’ enqui ry and pupils’ reflection for young musicians’ learning of expressive performance.
Relationship Between Egg Productivity and Insulin-Like Growth Factor-I Genotypes in Korean Native Ogol Chickens

Endocrine factors, such as steroid hormones and growth factors, regulate egg productivity in terms of the quantity of egg production, egg weight, sexual maturity, and the number of small yellow follicles (SYF). Insulin-like growth factors (IGF) are involved in the regulation of ovulation rate and ovarian follicular development in chickens, and a relationship between IGF-I genotype and egg weight has been reported. However, the effect of IGF on egg productivity in Korean Native Ogol chickens (KNOC) has been little studied. Therefore, this study was conducted to identify the relationship among endocrine factors (IGF-I, IGF-II, estradiol, and pro-gesterone), IGF-I genotypes, and egg productivity. Fre-(
Sequential Delivery of Live Attenuated Influenza Vaccine and Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in the Ferret Model Can Reduce SARS-CoV-2 Shedding and Does Not Result in Enhanced Lung Pathology

Cocirculation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza viruses could pose unpredictable risks to health systems globally, with recent studies suggesting more severe disease outcomes in coinfected patients. The initial lack of a readily available coronavirus disease 2019 (COVID-19) vaccine has reinforced the importance of influenza vaccine programs during the COVID-19 pandemic. Live attenuated influenza vaccine (LAIV) is an important tool in protecting against influenza, particularly in children. However, it is unknown whether LAIV administration influences the outcomes of acute SARS-CoV-2 infection or disease. To investigate this, quadrivalent LAIV was administered to ferrets 3 days before or after SARS-CoV-2 infection. LAIV administration did not exacerbate the SARS-CoV-2 disease course or lung pathology with either regimen. In addition, LAIV administered before SARS-CoV-2 infection significantly reduced SARS-CoV-2 replication and shedding in the upper respiratory tract. This study demonstrated that LAIV administration in close proximity to SARS-CoV-2 infection does not exacerbate mild disease and can reduce SARS-CoV-2 shedding.
High-dimensional Covariance/Precision Matrix Estimation under General Missing Dependency

High-dimensional Covariance/Precision Matrix Estimation under General Missing Dependency Seongoh Park The Department of Statistics The Graduate School Seoul National University A sample covariance matrix S of completely observed data is the key statistic to initiate a large variety of multivariate statistical procedures, such as structured covariance/precision matrix estimation, principal component analysis, and graphical models. However, the sample covariance matrix obtained from partially observed data is not adequate to use due to its biasedness. To correct the bias, a simple adjustment method called an inverse probability weighting (IPW) has been used in previous research, yielding the IPW estimator. The estimator plays a role of S under missing data context so that it can be plugged-in into off-the-shelf multivariate procedures instead of S. However, theoretical properties (e.g. concentration) of the IPW estimator have been only established under very simple structure
Correlation between nitric oxide levels and clinical features in patients with nasal polyposis

Background: Nasal polyposis (NP) is a multifactorial pathology with negative impact on quality of life. The pathogenesis of NP has not been fully elucidated. This limits the pathogenic treatment. Recent studies suggest that nitric oxide (NO) and its metabolites are involved in pathophysiological events of NP. Purpose of the study: to evaluate the tissue NO and nitrite/nitrate (NO 2- /NO 3- ) levels in patients with and without NP and to establish the relationship between NO levels and some clinical features. Material and methods: 86 recruited patients were divided into a case group (N 1 =43), patients with NP and a control group (N 2 =43), patients with septal deviations and turbinate hypertrophies. Visual Analog Scale (VAS) was used to evaluate the severity of nasal obstruction and olfactory disturbances. NO and NO 2- +NO 3- concentrations in tissue specimens were measured by spectrometric method. Results: Case group had significantly lower NO (U=173.5, p<0.001) and NO 2- +NO 3- levels (U=123.5, p<0.001). A negative correlation was found between VAS for nasal obstruction and NO levels (r s = -0.379, p<0.05), between VAS for olfactory disturbances and NO levels (r s = -0.531, p<0.001), and between endoscopic score and NO levels (r s = -0.758, p<0.05). Conclusions: Our results corroborate the previous findings. This underlines that NO levels depend on the patency of sinus ostium and the state of osteomeatal complex. Further studies, which take into account the role of NO in different rhinosinusitis endotypes, are needed to be performed in order to improve the NP management.
Dopaminergic mechanisfl*in the pathogenesis of schizophrenia

The dopamine hypothesis of schizophrenia has been the dominant theoretical construction guiding research and treatment of the schizophrenic disorders over the past generation. This hypothesis, in its simplest guise, posits the presence of a functional alteration in central dopaminergic systems in the brains of schizophrenic patients. Recent findings have resulted in a greater under- standing of the complexity of the central dopaminergic systems and have led to revisions of the hypothesis of a simple functional hyperactivity of central dopaminergic systems. These recent data suggest that there may be regionally restricted changes in the function of the mesotelencephalic dopamine system, and that these changes may be in opposite directions. Such changes may be associated with dysfunctions of interactions between distinct dopaminergic terminal field regions, and may be subserved by functional derangements in other transmitter systems or reflect regionally restricted changes in expression or function of distinct dopamine receptors or catecholamine synthetic enzymes.

A Novel Passive Cost-Effective Technique to Improve Radiated Immunity on PCBs

This paper proposes a novel simple cost-effective technique to improve the potential immunity of integrated circuits (ICs) to radiated electromagnetic (EM) disturbances. It is based on dielectric loading which lessens the susceptibility of ICs independently of frequency by confining the reactive fields inside the dielectric load. This has no side effects on the IC performance. To highlight the importance of the proposed technique, immunity testing was performed numerically both in near and far fields. A loaded IC (a microcontroller) was compared to an unloaded one through far-field measurements inside a transverse EM cell to indirectly assess the suitability of the proposed approach. Results show that loading the IC with non-ferromagnetic dielectric material not only effectively decreases its susceptibility to electric field, but also to magnetic field. Moreover, a significant difference of $\sim$48% less failure rate was achieved for the loaded compared to the unloaded IC demonstrating the usefulness of this technique as a potential solution for radiated immunity improvement.
Study of the Growth of a New Social Network Platform

—Nowadays, with the rapid development of social network sites (SNS), many efforts have been made on the analysis of such networks, which is important for us to enrich our social network knowledge and improve the SNS design. However, most analysis have focused on the very popular SNS, there is little comprehensive analysis of growing process of a SNS from the exact original stage, therefore, lacking of deep understanding how the SNS evolve over time. In this paper, a comprehensive growth data set of a new social network site constructed by our lab is examined to see the growing process of the network and to find some underlying growth mechanisms. This observation provides an empirical evidence of the Barabási-Albert (BA) model. During the observation, the number of new added links is shown to have a linear relationship with the number of new added users and there is a preferential attachment phenomenon in the link formation process. In addition, the degree distribution at different time points is presented to see the formation of the power-law distribution. Finally, the topological properties are found to be stable after a period of development, though the network is still growing.
Stem cells from rats with pulmonary hypertension reduce pulmonary parenchymal damage, medial hypertrophy of pulmonary arterioles, and right ventricular hypertrophy in rats with pulmonary hypertension

Background: Pulmonary arterial hypertension (PAH) is a chronic lung disease characterized by increased pulmonary artery pressure, pulmonary vascular damage and medial hypertrophy of pulmonary arterioles. Stem cell therapy may improve pulmonary damage in patients with PAH. Purpose: To test the effects of treatment with bone marrow-derived mesenchymal stem cells (MSCs) obtained from donor rats with monocrotaline (MCT)-induced PAH to recipient rats with MCT-induced PAH on ( i ) pulmonary artery pressure, ( ii ) lung histology, ( iii ) pulmonary arteriolar diameters, and ( iv ) right ventricular (RV) hypertrophy. This model was chosen to mimic autologous stem cell therapy. Methods: Female Wistar rats were divided in 4 groups, receiving either PBS (control, n=10), MCT (60 mg/kg, n=10), MCT (60 mg/kg) 14 days later followed by administration of 10 6 MSCs per rat i.v. (n=10), or 10 6 skin fibroblasts (SFs) per rat i.v. (n=10). MSCs were obtained from bone-marrow of PAH rats treated with MCT (60 mg/kg) for 28 days. SFs were obtained from healthy rats. At 28 days after MCT (or PBS) administration, the animal was sacrificed, lungs and heart were excised, weighed, fixed and examined by histology. Results: At 28 days after MCT-treatment, rats had PAH (RV peak systolic pressure of 42±17 vs. 27±5 mmHg in control; p<0.02), and increased lung weight (1.66±0.32 vs. 0.96±0.15 g in control; p<0.05). Lung histology demonstrated severe narrowing of precapillary arterioles, thickening of arteriolar walls (3.4 times increased vs. control; p<0.001), thickening of alveolar septa (3.5 times increased vs. control; p<0.001), and increased RV mass (by 63%; p<0.01). Treatment with MSCs for 14 days attenuated PAH (31±4 mmHg; n.s. vs. MCT60; n.s. vs. control), and almost normalized lung weight (1.16±0.24 g; p<0.05 vs. MCT60), wall thickness of arterioles (p<0.01 vs. MCT60), thickness of alveolar septa (p<0.01 vs. MCT60), and RV hypertrophy (p<0.01 vs. MCT60). In MCT-treated rats i.v. therapy with SFs from healthy rats had less beneficial effects than i.v. therapy with MSCs from PAH rats. These results suggest that autologous stem cell therapy may help to alleviate cardiac and pulmonary symptoms in patients with PAH.

Histomorphology, Hormonal Changes and Redox Imbalance in Aluminum-Induced Testicular Toxicity: The Mitigating Influence of Ethanolic Stembark-Extract of Prosopis africana.

:- The study aimed at mitigating effect of ethanolic stembark extract of Prosopis africana on aluminum-induced testicular toxicity in adult Wistar rats. Twenty-five Wistar rats of an average weight of 200g were grouped into five: Normal control, AlCl 3 (200 mg/kg/ d), 200mg/kg/d P. africana , AlCl 3 (200 mg/kg/ d) + 200mg/kg/ d P. africana and AlCl 3 (200 mg/kg/d) + 400mg/kg/d P. africana groups. All animals were fed orally and allowed access to water ad libitum for four weeks. Testicular histology, semen parameters, biochemical assays and testosterone hormone were assessed. The degenerative seminiferous tubule histoarchitecture due to AlCl 3 toxicity was improved by Prosopis africana extract. Notably, the group with extract alone showed superlative values in all investigated parameters relative to the other groups. This study also showed the significant reduction in testicular mass and parameters. There was improvement in sperm parameters in group co-treated with Prosopis Africana extract groups. This study showed reduced antioxidant level of SOD and increased MDA levels in the AlCl 3 group relative to the other groups. This study demonstrated the ability of ethanolic stembark-extract of Prosopis africana to mitigate aluminium-induced testicular toxicity on reproductive functions and the pro-spermatogenic properties of the compound in boosting andrological parameters. semen parameters, biochemical parameters and testosterone hormone of adult Wistar rats.

Approaches to Teaching L2 Writing A Move towards an Alternative Approach at the Arab tertiary level

( دللمجا ـ ةيوبترلا مولعلاو بادلآا في ةلمج 81 ( ددعلا ) 8 ةنس ) 8181م ABSTRACT The development of L2 (English as a second language) writing instruction can be seen as a succession of major approaches that have occurred in more or less historical progression all of which are proposed in English as the first language (L1) theory and practice. Based on the relevant existing literature, three approaches are still dominant and influential. They are: product approaches, process approaches, and genre approaches. The current writing instruction to teach EFL writing at the Arab tertiary level is characteristically inspired by product approaches. Such approaches have come under serious scrutiny for a number of reasons. field theory and and the a Writing instruction in
Hydrodynamics and morphodynamics of shallow tidal channels and intertidal flats. Doctoral thesis

Abstract : In this thesis, mechanisms which control morphodynamics of shallow tidal embayments are investigated analytically. In the process of exploring these mechanisms (specifically asymmetries in bottom stress, Tau, basis momentum and mass balances which govern flow in these systems are clarified. Temporal asymmetries in Tau are investigated via a new perturbation scheme which quantifies nonlinear processes and combines geometric controls on asymmetry into a single non-dimensional parameter. Implications of spatial asymmetries in Tau are investigated through stability criteria based on a uniform distribution of Tau. Morphologic observations of both tidal channels and intertidal flats are consistent with a uniform distribution of Tau at equilibrium. Investigation of morphodynamic mechanisms leads to scalings of momentum and continuity which diverge from classical models. Scalings for prismatic channels with strong tidal asymmetries indicate friction often dominates acceleration in the momentum equation. The resulting zero-inertia balance gives a time-varying diffusion equation which requires along-channel amplitude to decay. Uniform Tau justifies a new scaling of continuity for exponentially-shaped channels. In such channels, along-channel gradients in tidal velocity are small and are often dominated by gradients in cross-sectional area. The resulting first-order wave equation allows only amplitude, forward propagating waveforms which are independent of channel length. Tidal channels Hydrodynamics, Tidal flats.
FPGA Implementation of a New DTC Strategy Dedicated to Delta Inverter-Fed BLDC Motor Drives

Abstract This paper presents the field programmable gate array (FPGA) implementation of an ameliorated direct torque control strategy (DTC-2) for a brushless DC motor (BLDCM) fed by a reduced delta inverter, called also three-switch three-phase inverter (TSTPI). In this work, a DTC-fed BLDCM drive is treated by considering two strategies. The first strategy (DTC-1) emulates the operation of the conventional inverter where the original DTC control is applied. Based on the DTC-1 strategy, high ripples of the electromagnetic torque are registered during the sector-to-sector commutations. These ripples are due to the application of unbalanced voltage vectors. To overcome these drawbacks, an ameliorated strategy (DTC-2) is proposed. This second strategy consists in decreasing the sudden transition between lower and upper voltage vectors by the synthesis of an appropriate vector selection table. The particularity of this table is based on the application of switching voltage vectors during a defined period of each commutation sector operation. In this paper, the two DTC strategies are developed, simulated and checked under the Xilinx system generator environment. Both strategies are translated into a hardware implementation using an FPGA device (Virtex 5). The hardware co-simulation results clearly validate the performances of the association BLDCM-TSTPI under the second ameliorated control strategy DTC-2.
