Ordinary Mode Instability in a Cairns Distributed Electron Plasma

引用

Communications in Theoretical Physics 2018年第6期69卷 699-703页

作者： K.azra Z.Iqbal G.Murtaza Salam Chair Department of PhysicsG.C.UniversityLahore 54000Pakistan

Employing the linearized Vlasov-Maxwell equations, a generalized dispersion relation for the ordinary mode is derived by employing the Cairns distribution function. The instability of the mode and its threshold condition is investigated. It is found that the temperature anisotropy χ= TⅡ I⊥〉 1 required to excite the instability varies with density values whereas the growth rate is dependent on various parameters like non-thermMity A, equilibrium number density no and temperature anisotropy. It is found that with the increase in the values of any of the parameters A, no and X, the growth rate is enhanced and the k-domain is enlarged. The results are applicable for space plasma environments like solar wind.

AIM To investigate the quality of life(QOL) and its clinical and epidemiological correlates among people with type 2 *** This cross-sectional study was conducted in Tabriz, Northwest of Iran, including a total of 394 people with type 2 diabetes using convenient sampling method from November 2014 to March 2015. General information including demographic, socioeconomic status and lifestyle factors were collected by trained interviewers. Clinical information was retrieved from clinic's record and QOL was assessed using the 26-item WHOQOL-BRIFE questionnaire. Univariate and multivariate linear regression were performed to assess the related factors and QOL dimensions. RESULTS The mean of overall health related QOL was 52.11 ± 11.53 and the maximum and minimum dimensions wererespectively seen in psychological(60.38 ± 14.54) and social(38.32 ± 16.94) dimensions. The results of multiple linear regression showed a significant overall relationship between HRQOL and age(b =-1.48%, 95%CI:-0.03 and-2.93) level of education(b = 4.12%, 95%CI: 2.73 and 5.5), number of comorbidities(b =-2.41%, 95%CI:-3.89 and-9.41), and level of income(b = 1.98, 95%CI: 0.05 and 3.9), functional limitation(b =-3.59, 95%CI:-2.26 and-4.92) and psychological distress(b =-2.02%, 95%CI:-2.83 and-1.21). Level of education, functional limitation, psychological distress were associated with the score of physical, mental and environmental dimensions, and number of comorbidities was associated with the score of physical and mental dimensions. CONCLUSION Based on our findings, lifestyle modification and increasing facilities of clinics providing service can be effective steps to improve the QOL among people with type 2 diabetes.

Chloramination of wastewater effluent: Toxicity and formation of disinfection byproducts

引用

Journal of Environmental Sciences 2017年第8期29卷 135-145页

The reclamation and disinfection of waters impacted by human activities（e.g., wastewater effluent discharges） are of growing interest for various applications but has been associated with the formation of toxic nitrogenous disinfection byproducts（N-DBPs）. Monochloramine used as an alternative disinfectant to chlorine can be an additional source of nitrogen in the formation of N-DBPs. Individual toxicity assays have been performed on many DBPs, but few studies have been conducted with complex mixtures such as wastewater effluents. In this work, we compared the cytotoxicity and genotoxicity of wastewater effluent organic matter（Ef OM） before and after chloramination. The toxicity of chloraminated Ef OM was significantly higher than the toxicity of raw Ef OM, and the more hydrophobic fraction（HPO）isolated on XAD-8 resin was more toxic than the fraction isolated on XAD-4 *** DBPs were also isolated on the XAD-8 resin. N-DBPs（i.e., haloacetonitriles or haloacetamides） were responsible for the majority of the cytotoxicity estimated from DBP concentrations measured in the XAD-8 and XAD-4 fractions（99.4% and 78.5%, respectively）.Measured DBPs accounted for minor proportions of total brominated and chlorinated products, which means that many unknown halogenated compounds were formed and can be responsible for a significant part of the toxicity. Other non-halogenated byproducts（e.g.,nitrosamines） may contribute to the toxicity of chloraminated effluents as well.

Safety and Efficacy of Digoxin TherapymWhere Are We Now？

引用

Journal of Pharmacy and Pharmacology 2016年第3期4卷 128-134页

作者： azra Bajraktarevic Department for Pharmacokinetics University of Sarajevo Faculty of Pharmacy Sarajevo 71000 Bosnia and Herzegovina

The aim of our study was to determine the criteria and key factors for the effectiveness of digoxin therapy. A prospective opened-type study was carried out in conditions of everyday clinical practice. The concentrations of digoxin were quantified from blood samples taken following the achievement of drug steady-state （using AxSYM microparticle enzyme immunoassay-MEIA）. The risk/benefit ratio was evaluated based upon the correlation between measured blood concentrations of the drug and clinical response. Study results （100 decompensated patients） revealed that therapy indication field was correctly covered, showing a higher prevalence in elderly. On average, each examinee had 2 or 3 comorbidities. Applied daily dose of digoxin ranged from 0.053 mg to 0.25 mg. Renal function was assessed by creatinine clearance which is one of the key factors for the accomplishment of optimal digoxin serum concentrations （p 〈 0.05）. Co-administration of seven drugs was complicating factor for the management of rational therapy. 76/100 patients were within referent range （0.8-2.0 ng/mL）, while 13/100 were above the upper limit. Four side effects in total were recorded （nausea, vomiting, confusion）, whereas in only two patients digoxin was excluded from the therapy. Digoxin confirmed the justifiability of its use in contemporary clinical practice.

Seed Priming Influence on Early Crop Growth, Phenological Development and Yield Performance of Linola (Linum usitatissimum L.)

引用

Journal of Integrative Agriculture 2014年第5期13卷 990-996页

作者： Hafeez ur Rehman Muhammad Qaiser Nawaz Shahzad Maqsood Ahmed Basra Irfan Afzal azra Yasmeen Fayyaz ul-Hassan Seed Physiology Laboratory Department of Crop Physiology University of Agriculture Faisalabad Soil Salinity Research Institute Pindi Bhatian College of Agriculture Bahuddin Zakriya University Department of Agronomy PMAS University of Arid Agriculture

Reduced early crop growth and limited branching are amongst yield limiting factors of linola. Field response of seed priming treatments viz. 50 mmol L^-1 salicylic acid （SA）, 2.2% CaCl2 and 3.3% moringa leaf extract （MLE） including untreated dry and hydropriming controls was evaluated on early crop growth and yield performance of linola. Osmopriming with CaCl2 reduced emergence time and produced the highest seedling fresh and dry weights including Chl. a contents. Osmopriming with CaCl2 reduced crop branching and flowering and maturity times and had the maximum plant height, number of branches, tillers, pods and seeds per pod followed by MLE. Increase in seed weight, biological and seed yields was 9.30, 34.16 and 39.49%, harvest index （4.12%） and oil contents （13.39%） for CaCl2 osmopriming. Positive relationship between emergence and seedling vigor traits, 100-seed weight, seed yield with maturity time, 100-seed weight and seed yield were found. The study concludes that seed osmopriming with CaC12 or MLE can play significant role to improve early crop growth and seed yields of linola.

Second-Order Kalman Filtering Application to Fading Channels Supported by Real Data

引用

Journal of Signal and Information Processing 2016年第2期7卷 61-74页

作者： azra Kapetanovic Redhwan Mawari Mohamed A. Zohdy Department of Electrical and Computer Engineering Oakland University Rochester MI USA

The lack of effective techniques for estimation of shadow power in fading mobile wireless communication channels motivated the use of Kalman Filtering as an effective alternative. In this paper, linear second-order state space Kalman Filtering is further investigated and tested for applicability. This is important to optimize estimates of received power signals to improve control of handoffs. Simulation models were used extensively in the initial stage of this research to validate the proposed theory. Recently, we managed to further confirm validation of the concept through experiments supported by data from real scenarios. Our results have shown that the linear second-order state space Kalman Filter (KF) can be more accurate in predicting local shadow power profiles than the first-order Kalman Filter, even in channels with imposed non-Gaussian measurement noise.
