Authors:   Asst. Professor and Head, Dept. Of English, Dr. RafiqZakaria College for Women, Aurangabad., Shakir Nilofer
Published: November 2020

The events in the novel Moth smoke, by Mohsin Hamid are based in Lahore, Pakistan. The writer takes us back in time to the Lahore of the Mughal era. He highlights a turbulent period in Mughal history when the ageing Monarch, Shah Jahan was distressed over the question of succession to the throne. A Sufi saint had predicted that his younger son Aurangzeb would become the king. The writer discusses the political tension of the times. The drive for succession involved a series of diplomatic moves and strategies which the four Mughal Princes adopted to survive the political storm that was generated by the conflicts related to the war of succession. The novel focuses on the late 90s in Lahore. Mohsin Hamid draws a parallel between the political disturbance in the 16th century and the Lahore of present times. The Lahore of the late 90s is in the grip of serious political and social crises. The hostility gripping the two countries of the subcontinent, India and Pakistan is portrayed through the nuclear tests conducted first by India and immediately afterwards by Pakistan in 1998. He focuses on the disintegration of the country and highlights the rampant corruption, drugs, and class wars. The intrigues and conspiracies hatched in the court and harems of Emperor Shah Jahan bordered on the lust for power or supremacy. The novel highlights the impulses, dreams and ambitions which motivate the actions of the characters in the two different time zones and how they finally lead to defeat and death.

Published: November 2020

The state of Jammu and Kashmir (now a UT after the abrogation of article 370) is not only the casus belli of three wars between India and Pakistan but is also a possible nuclear flashpoint. Thus the security situation in Jammu and Kashmir (J&K) is a cause of concern not only for the two states but also for South Asia and the entire world. The state-sponsored proxy war in J&K and the resultant militarization of the entire state has turned the situation into a vicious spiral that threatens to go out of control every few years since the 1980s. The dynamics of Kashmir valley have also oscillated from peaceful marches on one end to the forced exodus of Kashmiri Pandits, mass murders by the terrorists, heavy-handedness by the security forces, and violent protests across the Kashmir valley. Amongst this melee of constant violence and curbs on a day to day freedom, the ultimate losers are the people of the state. The aspirations and happiness of these common people have somehow been lost on the state and national governments, the curbs on the flourishing of civil society, and the environment of fear generated by the so-called militants and militarization of the state. An analysis of these mass protests gives out the general mood of the public if not the actual aspirations of the people. The factors causing the security situation in the valley to deteriorate need to be taken cognizance of not only in the domain of law and order but also in the modifications to the approach required to renew and reestablish a compact with the people of the state.

The construction activities are increasing day by day. Due to this the natural sand is increasing its scarcity and its price in all parts of the country. Therefore reducing the consumption of natural sand in construction is a major issue while considering the both environment and economic view. The sustainable development for construction involves the use of nonconventional, innovative materials and recycling of industrial by products in order to compensate the lack of natural resources. Copper slag is one of the industrial by-product obtained during manufacture of copper. This paper reviews the characteristics of copper slag and its effects on the engineering properties of cement, mortar and concrete.

Acute compartment syndrome after snakebite is considered to be quite rare and there is still a lot of controversy in regard to its diagnosis and management as it has been reported by the little available medical literature on the topic. It is in this context that our series assumes importance as we report our experience relating to management and outcome of 16 consecutive cases of compartment syndrome from snakebites. A 15-year retrospective study was conducted on all adult patients with compartment syndrome following snakebites, who were admitted between April 2005 and December 2019 in our institution. Due to non-availability of equipment to measure intracompartmental pressure, the diagnosis of compartment syndrome was based on clinical judgment. There were 10 (62.5%) male and 6 (37.5%) female, with a mean age of 32.1 ± 7.8 years. Bite site was mostly in the lower limbs (62.5%). Based on clinical severity, 2 (12.5%), 10 (62.5%) and 4 (25%) patients were classified into classes I, II, and III, respectively. FAV-Afrique® antivenom was administered to 12 (75%) patients in doses ranging from 1 to 5 vials by patients. Fasciotomy was performed in all cases and the median time from admission to surgery was 5.8 hours (range: 4– 9hours). The mean hospital stay was 16 days and follow-up of patients has shown good results: normal limb function was regained in all cases. In summary, acute compartment syndrome following snakebite is not rare in our context and must be treated by performing early fasciotomy without any delay after diagnosis.

COMPARISON STUDY: INTERMITTENT ANTIGRADE WARM CARDIOPLEGIA VERSUS ANTIGRADE COLD INTERMITTENT BLOOD CARDIOPLEGIA FOR MYOCARDIAL PROTECTION DURING ELECTIVE ON PUMP CORONARY ARTERY BYPASS GRAFTING IN EARLY POST-OPERATIVE PERIOD
Authors:   ijar, F. El-Safty Mahmoud , Gamal Bakr Hazem , Abd El-Hady Mohamed , Mahmoud Yahia
Published: November 2020

Background: Defending the heart against potential damage during cross-clamping is the most important and vital step to ensuring a successful surgical outcome(1). The creation of cardioplegia solutions was one of the major advances in cardiac surgery that allowed surgeons to conduct complicated surgical procedures to avoid myocardial injury (14). Treating cardioplegia at a cool temperature would be a significant factor in lowering myocardial metabolism. However, the reduction in myocardial metabolism due to hypothermia, compared with that achieved by diastolic arrest, is usually very negligible. Since Normothermias enzymatic and cellular processes work better (7). Owing to the propensity of the heart to resume electrical operation during normothermia, however, this must be administered consistently or only with short interruptions (4). Terminal warm blood cardioplegia (hot shot) is normally done just before the elimination of the aortic cross-clamp since it has been demonstrated that myocardial metabolism is increasing (23). Methods: A prospective controlled randomised study (200 hundred patients aged 40 to 65 years of both sexes underwent elective CABG pump surgery) will be included. They will be divided into three groups of patients: Group I:includes 100 Patients who received intermittent cold blood cardioplegia. Group II:includes 100 Patients who received intermittent warm blood cardioplegia with controlled reperfusion for 3 minutes before aortic unclamping. Study made from January, 2019 to August, 2020, at National Heart Institute.All patients were thoroughly evaluated preoperatively, intraoperatively, and postoperatively. Results: We hypothesized that in our patient cohort, warm blood cardioplegia could be as successful as or even better than the conventional antegrade cold blood cardioplegia. Patients were randomised into two similar blocks, each of which consisted of 100 patients, each of whom obtained one of the two cardioplegic solutions. Our analysis did not indicate a statistically important difference in the post-operative release of myocardial biomarkers (Troponin I) & CK in both classes. This finding did not significantly reflect the clinical outcome of our patient, which may indicate similar myocardial protection in primary low-risk CABG patients for both cold and warm blood cardioplegia. Conclusion: During the time of cardiac arrest, both methods tend to enable an equal and adequate approach for myocardial defence. To attain improved myocardial defence, warm blood cardioplegia needs a shorter administration interval. Therefore, the choice between one type of cardioplegia and the other remains at the discretion of the surgeon. The statistically minor variation found in the release of myocardial enzymes did not translate into distinct clinical results.

This study attempts to identify the Bank Specific and Macro-economic Determinants of The United Arab Emirates Commercial Banks Profitability measured by Return on Assets, Return on Equity and Net Interest Margin. The study uses bank-specificand microeconomic factors as independentvariables. The bank-specific factors include bank size, capital adequacy, assets quality, liquidity, deposits, diversification ,business mix, and efficiency, while the macroeconomic factors include real Gross Domestic Product growth, Inflation Rate, and Real Interest Rate.Regression models were used to relate bank profitability ratios to the independent variables built on panel data for the period 2013-2019 of sixteen commercial banks operating in the United Arab Emirates.The results of the study show thatassetsize, liquidity, off-balance sheet activities, and diversification have significant impact on profitability as measured by theNet Interest Margin. In addition, loans under follow-up to total loans, and managerial efficiency are found to behighlysignificantvariables of profitability in the context of the United Arab Emirates commercial banks as measured by Return on Assets and Return on Equity. Furthermore, diversification has a significant impact on profitability as measured by Return on Assets. The remaining bank-specific factors (capital adequacy, loans to total assets, liquidity, deposits to assets ratio, and operating expenses to total assets ratio) and macroeconomic factors have no significant effect on bank profitability. The results of the study suggest that banks can improve their profitability through maintaining high operating income, decreasing the size of non-performing loans, full utilization of liquid assets, more concentration on the main activities, efficiently managing their operating expenses, and taking advantage of the Gross Domestic Productgrowth , inflation and Interest Rate changes to improve the banks performance and profitability. In addition, it is recommended to make further studies on the banks performance with an expanded scope which is tobe extended to other industries.

Micro hydropower projects and diversion based irrigation projects are dependent on the amount of water flowing in the river of concern. Analyses of historical River Flow information are crucial to understand its pattern, frequency and predictability. Statistical analysis is the basis for a better scientific comprehension of the river flow system. Based on this information designing of such projects as well as making management plans for any future eventualities are possible. In this paper historical discharge information for a period of 19 years is collected and analyzed. Based on the water level and volume of discharge information of the river for the year 1995, various stage discharge rating curves are prepared. The best fitted curve is used for the estimation of the discharge for the remaining years where only the stage information is available. Daily discharge hydrographs for 19 years is prepared along with annual discharge computation for each of the 19 years of observation period. Preparation of flow duration curve helped to understand what is to be expected minimum from the river and what could be the most risky situation for a river project in this river and make necessary allowances for designing such project. Finally seasonal and monthly time series models are prepared so that the future discharge could be scientifically forecasted for predicting the future of such projects.

Authors: Kaiser Mohammad Salim , Fazlullah Fahim , Ahmed Sheikh Reaz
Published: November 2020

A parametric study has been conducted on the characterization of machined surfaces of some commercially available polymeric materials structures obtained under surface finishing. More specifically, the major mechanical properties of the machined surface, namely, surface roughness, hardness, temperature, as well as chips deformation are evaluated under different machining conditions, and are analyzed in a comparative fashion for a number of commercial polymeric material samples that include Acrylic (Perspex), High Density Polyethylene (HDPE) and Unplasticized Polyvinyl Chloride (uPVC). The machining of the samples is realized through a standard horizontal shaper machine with HSS single point V-shaped cutting tool at different cutting speed and depth of cut. The measured results show that the surface properties of the polymeric materials are affected quite significantly by the change of machining parameters. Microstructures of the chips reveal that crack-like flaws are formed at higher cutting speeds and lower depths of cut.
Nonlinear dynamic response and deformation analysis of soil under the explosion shock loading
Authors: Wang Iau-Teh
Published: November 2020

Energy is released during explosions, and this creates shock waves. The dynamic pressure generated from an explosion is transmitted through soil in the form of compression waves. In military engineering and industrial safety protection, soil, a blast-resistant material, is used to achieve blast resistance. This study used the blast pressure and ground acceleration measured in an experimental explosion to verify the results of finite element numerical analysis. A fluid–solid interaction numerical analysis method was employed to simulate a trinitrotoluene explosion on the ground. Through analysis of the dynamic characteristics of soil after an explosion, the relationship between the dynamic stress wave formed by the explosion and the plastic deformation of the soil was studied. The results may provide a reference for the design of blast-resistant protective soil layers.

Authors: Sun Weigang , Xu Juncai
Published: November 2020

The prestressed concrete cable-stayed truss T- frame bridge is a novel type and complex structure. Truss damage is a common form of distress in this type of bridge. For studying the mechanical properties of truss members under the condition of the truss rod, a finite element model is established for analyzing the damage or failure of the truss rod. The effects on the deflection and frequency are compared and analyzed under the condition of damage or failure of the truss rod. The results show that the damage of the truss members has a significant effect on the deflection and frequency of the main beam. The damage of the upper chord affects the deflection of the entire T-beam, and the damage scope of the web member is limited to the abdominal area. The relationship between the damage of the truss members and the deflection of the main beam is nonlinear. Damage to truss members results in a reduction in fundamental frequency. Whole bridge truss damage has a more significant effect on frequency. Upper chord damage has a more significant effect on frequency than web members.

Authors: Li Youlin , Hu Yu , You Wenqiao , Zhou Guangming , Peng Guilong
Published: November 2020

Activated carbon/CuO (AC/CuO) composites were prepared through a facile one-step hydrothermal method and used as a bifunctional material for adsorption and catalysis degradation of bisphenol A (BPA). The composite was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and X-ray powder diffraction (XRD). The obtained AC/CuO exhibited excellent adsorption and catalytic performance. The maximum adsorption capacity of BPA on the AC/CuO was 319.03 mg/g according to the Langmuir fitting. At an initial BPA concentration of 20 mg/L, the BPA degradation efficiencies were maintained above 96% for 15 min by using 20 mg/L AC/CuO and 2 mM peroxymonosulfate (PMS). Moreover, the relationship between adsorption and catalytic degradation was also investigated. The results indicated that the pre-adsorption disfavored the degradation reaction. This work not only provides a novel preparation method for AC/CuO catalyst, but also gives a deeper insight into the mechanisms between adsorption and catalytic degradation.

Published: November 2020

The performance of a continuously operated laboratory-scale rotating biological contactor (RBC) was assessed for the removal of heavy metals viz. Cu(II), Cd(II) and Pb(II) from synthetic wastewater using artificial neural networks (ANNs). The RBC was inoculated with Sulfate Reducing Bacteria consortium (predominantly Desulfovibrio species), and the performance was evaluated at different hydraulic retention times (HRTs) and inlet heavy metal concentrations. A feed-forward back-propagation neural network model was developed using 90 data sets obtained over a period of three months, to predict the removal of heavy metal (HMRE) and COD (CODRE). The predictive capability of the model was evaluated in terms of the coefficient of determination (R) and mean absolute percentage error between the model fitted and actual experimental data, whereas sensitivity analysis was performed on the input parameters by determining the absolute average sensitivity (AAS) values. The higher AAS value of the HRT compared with that of inlet heavy metal concentration suggested that the change of HRT has a significant influence on HMRE and CODRE. Overall, the results obtained from this study demonstrated that ANNs can efficiently predict RBC behaviour with regard to heavy metal and COD removal characteristics under the prevailing operational conditions.

Published: November 2020

With the continuous development of the population and social economy, the spatial and temporal distribution of water resources in arid inland river basins is severely uneven, and there is a sharp contradiction between agricultural water use and ecological water use. Irrational development and utilization of water resources has led to many problems, such as shrinking oases and drying lakes. To solve this problem, this study proposes a multiobjective, multiwater-source, ecological stability-oriented double-layer model for optimal allocation of water resources based on the large-scale system decomposition–coordination principle, the water balance principle, and a water supply and demand forecasting model. This model can resolve the contradiction between agricultural water use and ecological water use by optimizing and adjusting the crop planting structure, industrial structure, and the amount of water allocated to and groundwater level in each region and thereby achieve ecological stability and restoration of oases. The developed model was applied to the Heihe River Basin in an inland region of Northwest China. The long-term time series data of 2000–2016 were used to construct and calibrate the model. Finally, the practical ecological stability-oriented plan for conjunctive allocation of surface water and groundwater in different plan years was proposed. This model enriches the research results related to the conjunctive allocation of surface water and groundwater and provides a reference for the ecological restoration of oases in arid inland river basins.
Experimental study on the performance of modified flocculant (PEI-T) for removal of turbidity and heavy metals from aqueous solution

Published: November 2020

The current study was focused on the evaluation of the performance of a modified flocculant (PEI-T) for the removal of turbidity and heavy metals from wastewater. Thioglycolic acid was introduced into the molecular chain of cationic flocculant polyethyleneimine (PEI) through an amidation reaction to form a new flocculant PEI-T. Results revealed that: (a) PEI-T and PEI had similar turbidity removal effect, but PEI-T had a good function of catching heavy metal copper and mercury; (b) when Cu2+ and turbidity-causing substances coexist in a water sample, Cu2+ and turbidity-causing substances promote the removal of each other and the residual concentration of Cu2+ and turbidity decrease further; and (c) the presence of Ca2+ and Mg2+ can promote the removal of copper ions by PEI-T.
Predicting failures in electronic water taps in rural sub-Saharan African communities: an LSTM-based approach

There is a growing need to sustain solar-powered water taps in most parts of the sub-Saharan Africa. The frequent failure of the water taps gives rise to intermittent water supply and poor service delivery by the water service providers. The challenge is to foresee and predict the failure of these water systems before they occur. This study develops a scalable machine-learning model for failure prediction in electronic water taps to ensure timely maintenance of the taps. Specifically, we develop a model based on long short-term memory (LSTM) to efficiently make failure predictions with noisy heterogeneous time-series data from rural water taps. Results from the experiment prove that the proposed model can effectively classify activities and patterns in various time-series datasets. With the proposed model, the failures of the solar-powered taps due to abnormal events can be successfully predicted well in advance, with an accuracy of 78.54%. Based on the data analyses, common causes of failures are presented.

Aim/ Background: The holistic approach in medicine refers to addressing an individual as a whole. Family physicians should be familiar with psychological as well as physical problems of their hemodialysis patients. This study aims to measure depressive mood levels of patients in a hemodialysis center, and to investigate the potential risk factors with a holistic approach. Method: This study was conducted on patients receiving treatment at a private hemodialysis center. During the hemodialysis session, the patients’s blood samples were taken, and serum phosphorus, creatinine, albumin, and hematocrit levels were measured. A semi-structured questionnaire form was used to investigate the sociodemographic characteristics and the Beck Depression Inventory (BDI) was used to determine depressive mood level of the patients. Results: This study was conducted on a sample of 88 patients (33 female, 55 male). The mean BDI scores were 16.7±9.8, and when the cut-off point of BDl was taken as 15, the rate of depressive mood was %56.8 for hemodialysis patients. We evaluated the duration of illness, family structure, educational level, having non-renal comorbid disease, employment status, economic status, and also blood creatinine, albumin, phosphorus, and hematocrit levels. The mean BDI score was significantly lower in patients who lived in simple nuclear families with fewer than six individuals at home. Conclusion: The holistic approach is essential, especially in chronic disease follow-up in primary healthcare. Family support and psychological evaluation with a holistic approach are vital for hemodialysis patients.

Purpose: Identification of women’s attitudes towards early diagnosis of cervical cancer is important in terms of overcoming the barriers to the solution to a global health problem. In this regard, the purpose of this study is to identify women’s attitudes towards early diagnosis of cervical cancer. Methods: This descriptive and cross-sectional study utilized a stratified, proportional sampling method. The participants were 1248 women aged between 20 and 64 who applied to the Maternity and Children Hospital polyclinics due to any reason. Data were collected through the socio-demographic form which was originally developed by the researchers in line with the literature and the Attitude Scale toward Early Detection of Cervical Cancer. Results: Of all the participants, 66.6% were found to have a regular gynecological examination. Almost half of the women who did not undergo regular examination reported to have done so because they felt embarrassed. Attitudes of women towards early diagnosis of cervical cancer were found to be at moderate level. Age, education level, financial situation, and being married were identified as the factors that affected attitudes towards early diagnosis (p<0.05). Perceived susceptibility, seriousness, and benefits of women who had regular gynecological examination were found to be significantly higher than those who did not. Conclusions: In line with the findings, although there is a reliable and accessible test that enables early diagnosis of cervical cancer, medium level of attitudes among women is an important barrier in preventing and decreasing deaths caused by cervical cancer.
