Published: August 2020

In order to study the tribological properties of titanium alloy materials and reinforced PTFE pairs treated by surface nitriding modification in seawater environment under low speed and high load, the physical properties of surface nitriding modified treatment were observed and measured with Ti-6Al-4V ELI as the substrate, and the samples of substrate and surface nitriding were modified as disks to 25% fiberglass , 15% glass fiber +5% graphite and 60% tin bronze reinforced PTFE as distribution pins, the friction properties of substrate and surface nitriding modification layer in seawater environment were studied by friction tester. The results show that the friction coefficient between titanium alloy and auxiliary pair is above 0.1, the friction coefficient of titanium alloy surface treatment specimen is lower than that of TC4 titanium alloy, the wear of surface nitriding modified treatment sample is significantly slight, the friction coefficient of 60% tin bronze distribution is the highest, and the friction coefficient of 15% fiberglass +5% graphite is about 15% higher.
Influence of Alkali Treatment and Fiber Content on Mechanical Properties of Pineapple Leaf Fiber (PALF)-Reinforced Cement-Based Composites via Full Factorial Design
Authors: Esper Charmane Dawn H. , Canseco Hana Astrid R.
Published: August 2020

In tropical regions such as the Philippines, pineapple leaf fiber (PALF) is abundantly available as a low-cost and renewable source for industrial purposes. In this research, PALF was used as a reinforcing material for cement-based composites to open up further possibilities in waste management. Since natural fibers are not fully compatible with the matrix due to their hydrophilic nature, surface treatment is necessary to enhance the fiber-matrix bonding. Fibers were treated using sodium hydroxide (NaOH) with varying concentrations (4%, 8% and 12%) for 6-hr immersion time at room temperature. PALF was then added at varying content (1%, 4% and 7% w/w cement) to the concrete mixture with a design mix ratio of 2:1 (sand: cement) and a constant water-cement ratio of 0.55. The samples were mechanically characterized after 28 curing days following ASTM C209 and ASTM C473. Full factorial experimental design (FFED) was used to investigate the effects of alkali treatment and the fiber content on the mechanical strengths of the composite. Experimental methods, analysis of variance (ANOVA) and normality test were carried out to evaluate, analyze and validate the results. The best results for tensile strength parallel to the surface and flexural strength at 2.028 MPa and 1.495 kN, respectively, were observed at composites with 1% PALF with 4% NaOH. Meanwhile, composites with 1% PALF with 12% NaOH showed the best result for tensile strength perpendicular to the surface at 1.681 MPa. According to ANOVA results, only the model for the tensile strength perpendicular to the surface showed a curvilinear behavior (p-value=0.012). Results revealed that the factor with the most significant effect was the interaction of the fiber content and alkali treatment on the tensile strength parallel to the surface (p-value=0.000), tensile strength perpendicular to the surface (p-value=0.001) and flexural strength (p-value=0.001).

Published: August 2020

Amine-modified solid sorbents have attracted extensive interests in post-combustion carbon capture for power plants. Among various amines, polyethyleneiemine (PEI) is likely to be the most effective and promising candidate. However, previous studies have mainly focused on examining various supports to increase PEI loading and then enhance CO2 adsorption capacity. In this study, one rare earth element (Ce) and 6 first-row transition metals (from V to Cu) in the oxidation states impregnated on PEI incorporated γ-Al2O3 were prepared and investigated as potential catalyst/promotor for base-catalyzed reaction. Thermodynamic analysis, including isothermal and quasi-static CO2 adsorption tests, were implemented to evaluate the performances amongst the 7 metal oxides. The results showed that MnO2, CeO2 and Fe2O3 showed a better performance in isothermal CO2 adsorption at 75°C. Upon quasi-static tests, the results also indicates that the peak adsorption temperatures (Tpeak, a) of V2O5 and Cr2O3 shifted to high temperature region, whilst opposite behavior of MnO2 was observed. In preliminary study, density functional theory (DFT) was also adopted to assist the screening of metal oxide in terms of bond length and adsorption energies.

Middle East respiratory syndrome coronavirus (MERS-CoV) is a highly pathogenic human coronavirus causing severe disease and mortality. MERS-CoV infection failed to elicit robust IFN response, suggesting that the virus might have evolved strategies to evade host innate immune surveillance. In this study, we identified and characterized type I IFN antagonism of MERS-CoV open reading frame (ORF) 8b accessory protein. ORF8b was abundantly expressed in MERS-CoV–infected Huh-7 cells. When ectopically expressed, ORF8b inhibited IRF3-mediated IFN-β expression induced by Sendai virus and poly(I:C). ORF8b was found to act at a step upstream of IRF3 to impede the interaction between IRF3 kinase IKKε and chaperone protein HSP70, which is required for the activation of IKKε and IRF3. An infection study using recombinant wild-type and ORF8b-deficient MERS-CoV further confirmed the suppressive role of ORF8b in type I IFN induction and its disruption of the colocalization of HSP70 with IKKε. Ectopic expression of HSP70 relieved suppression of IFN-β expression by ORF8b in an IKKε-dependent manner. Enhancement of IFN-β induction in cells infected with ORF8b-deficient virus was erased when HSP70 was depleted. Taken together, HSP70 chaperone is important for IKKε activation, and MERS-CoV ORF8b suppresses type I IFN expression by competing with IKKε for interaction with HSP70.

Authors: Durán-Solórzano Stéfano Alexander
Published: August 2020

Entre las labores más complejas para los profesionales de la salud mental que se dedican a la evaluación de personas se encuentra la obtención de perfiles psicológicos, puesto que se requiere un nivel elevado de experticia, sobre todo cuando se pretende valorar si la persona presenta características relativas a la transgresión de normas. Por otra parte, para desarrollar estrategias de detección de sujetos transgresores de normas en la evaluación grafológica, es necesario comprender algunos conceptos básicos como la definición de grafología, la importancia de conocer la sectorización de la letra y sus áreas. Es por estas razones que el objetivo del presente manuscrito es analizar la bibliografía referente al perfil psicológico de los individuos trasgresores de normas y su relación con la grafología como mecanismo de detección de este comportamiento. Se logró definir las características psicológicas de los sujetos transgresores de normas, mediante encuadres teóricos: el primer encuadre fue la visión médico psiquiátrica mediante el DSM. El segundo encuadre fue el psicoanálisis, que desde el constructo de perversión, argumenta que el sujeto goza quitándole el estatus de sujeto al otro.

Authors: Dr. Mayank Surana  , Dr. Vineeta Pande  , Dr. Sharad Agarkhedkar  , Dr. Ajit Teegala
Published: August 2020

Allergy, is a clinical expression of soluble factors like IgE, histamine or eosinophils found in serum or plasma of such patients. The products that are responsible for allergy are called as Allergens. Allergens normally induce IgE production which leads to type 1 hypersensitivity response on subsequent exposure to the same allergen. The target organs are mostly nose, lung, skin and gastrointestinal tract. Atopy is also considered as a triad of Atopic dermatitis, allergic rhinitis and bronchial asthma. Raised serum IgE and AEC are proven indicators of allergic phenomenon. Various studies show relationship between serum Immunoglobulin E level and total eosinophil count in population suffering from allergic diseases. Serum total Immunoglobulin E, total eosinophil count and specific IgE are all helpful for the diagnosis and treatment of allergic diseases. Objectives: 1.To Evaluate Serum Total IgE level in Children with allergic diseases.2. To Evaluate Absolute Eosinophil Count (AEC) in children with allergic diseases.3. To Correlate Serum Total Immunoglobulin E Level and Absolute Eosinophil Count (AEC) with allergic diseases. Methodology: Cross sectional study with 100 children in the age group 2-12 years with nasopharyngeal allergies (like bronchial asthma and atopic rhinitis) and skin allergies (like atopic dermatitis, urticaria) ,eye allergies were enrolled and serum IgE levels and AEC levels was done. Results: In present study Absolute eosinophil count was raised in 58% of cases Serum IgE was raised in 54% of cases. In present study, of 58% cases with raised Absolute eosinophil count 81% (47 cases) showed raised serum IgE levels. Conclusion: Absolute eosinophil count and serum Total IgE has been considered as a significant marker of allergic state and can be used as a marker of allergic response in atopic individuals. Raised serum IgE and AEC are more in nasobronchial allergy as compare to other systemic allergies. The elevated level of serum Total IgE and Absolute Eosinophil Count both shows Significant Correlation thus can be considered as a dependable laboratory investigation in diagnosing and categorizing allergic diseases.

Published: August 2020

The Nitric oxide (NO.) is an intermediate between molecular oxygen (O2) and nitrogen (N2).  N2 has low solubility and readily diffuse through membranes as easily as through cytoplasm and is a strong oxidant. Molecular oxygen propagates free radical damage and has a central role in oxidative stress and in infectious diseases. In our study nitric oxide and lipid peroxide (MDA) level is measured in 100 healthy controls   and in 60 infectious diseases patients.   Both nitric oxide level (P<0.001) and lipid peroxide (p<0.001) was found significantly high in infectious diseases patient group than normal healthy control. The study concludes that NO· is the effector molecule that initiates the cytotoxic effects by increasing the oxidative stress.

Published: August 2020

The background of this research was how Malaysian students maintain their Malaysian language in Medan even when they were far from their language domain. When a certain language speaker moved to other area which use different language and interact with them, they tend to adopt that new language. The objectives of this study wire to find what factors that induce maintainability of Malaysian language by Malaysian students in Medan, and how is the maintainability of Malaysian language realized by Malaysian students in Medan and also why the maintainability of Malaysian language is the way it does. This research used descriptive research by giving the Malaysian students a questionnaire and interviewing them. There were 21 Malaysian students as informants, 16 men and 5 women. It was found that the maintainability happened because Malaysian students were living in group, so they still use Malaysian language regularly. Even when they were far from Malaysian language domain, they still accessed Malaysian language media such as music, news, TV, radio etc regularly and still active in chatting application with their friends who are still living in Malaysia and use Malaysian language. They realized they maintainability of Malaysian language by joining Malaysian community, where many Malaysian students gather and speak in Malay, they also have good language attitude towards Malaysian language. Those happened because when they lived in a foreign environment they tried to find other Malaysian students to fell like home. That makes them living together with other Malaysian students in group.

Impact of Anxiety and Depression on Quality of Life among Patients Undergoing Hemodialysis: A Scoping Review
Authors: AlNashri Fatima I. , Almutary Hayfa H. , Al Nagshabandi Elham A.
Published: August 2020

Context: Chronic kidney disease (CKD) is a life-threatening problem of global concern. Living with CKD is associated with many psychological problems, including depression and anxiety, which can directly or indirectly affect the quality of life. Only one review in the existing literature has assessed these associations among CKD patients using different dialysis modalities. However, the experience of these symptoms could be higher among patients on hemodialysis therapy. In this purview, there is a need to narrow the previous work to be more focused on hemodialysis patients.

Aim: This scoping review aims to determine the gaps in the knowledge about the impact of anxiety and depression concerning QOL among people undergoing hemodialysis.

Methods: The studies selected were those examined the relationships between depression or/and anxiety with quality of life in adult patients on hemodialysis. The CINAHL, MEDLINE, and Pub Med databases were searched for literature published between January 2012 and December 2019. The quality of the included studies was also apprised. Eleven studies met the inclusion criteria.

Results: Six studies examined the impact of depression and anxiety on the quality of life. Five studies identified from the review have examined the relationships between depression and quality of life. It was established that the prevalence of anxiety and depression was high among hemodialysis patients, and the same was associated with low quality of life.

Conclusion: The literature review highlights the negative associations between anxiety, depression, and quality of life among hemodialysis patients. It is, therefore, essential to screen hemodialysis patients frequently for anxiety and depression using a short-form questionnaire. This screening would allow for providing early interventions, and the potential deterioration of quality of life could be prevented. Further longitudinal studies are needed to assess these relationships. Additionally, further research is needed to determine effective interventional programs to improve the overall quality of life.
FREQUENCY OF IN HOSPITAL MORTALITY IN PATIENTS WITH HIGH NEUTROPHIL/LYMPHOCYTE RATIO PRESENTING WITH ST ELEVATION MYOCARDIAL INFARCTION
Authors: Siraj Jawad , Ali Umair , Ahmed Tanveer , Ali Haider
Published: August 2020

Objective: To determine the frequency of in-hospital mortality in patients with high NLR presenting with STEMI. Methodology: Consecutive patients with STEMI and high NLR presenting at Cardiology department, Lady Reading Hospital, Peshawar were evaluated for our study. Out of the 236 patients admitted from 1st September 2015 to 28th February 2016, 191 patients qualified for study inclusion. NLR was calculated by dividing the total number of neutrophils over the total number of lymphocytes obtained via a computerized heamogram. A high NLR was defined as value >4.7. In hospital mortality and the effect of various class of patients with or without conventional risk factors was assessed. Results: The mean high NLR in study population was 6.38±1.28. In-hospital mortality due to cardiac cause was 12% (n=23) which included 8.37% (n=16) males. Statistically significant higher values of mean high NLR were found to be associated with in-hospital mortality and presence of conventional risk factors including hypertension, diabetes, and smoking with the exception of hypercholesterolemia. Among the patients who died, more had adverse events in form of higher Killip class and arrythmias. Conclusion: High NLR has fair prognostic value in patients presenting with acute STEMI. Raised values correlate well with the presence of conventional risk factors which increase the risk of post MI adverse events and appears additive to conventional risk factors and biomarkers.

ECG FEATURES OF TAKOTSUBO CARDIOMYOPATHY IN PAKISTANI PATIENTS
Authors: Ahmed Syed Waqar , Tipoo Fateh Ali
Published: August 2020

Objectives: Takotsubo cardiomyopathy (TC) is a distinct clinical disease that mimics the clinical and ECG features of ST elevation Myocardial Infarction (STEMI). Differentiating between TC and STEMI is essential since they have different treatment strategies and prognosis, especially in the acute phase. Since ECG is the first investigation for a patient with clinical features of STEMI, recognizing ECG features of TC early on is invaluable. There is a dearth of literature from the South Asian population describing ECG features of TC. Hence we investigated the different ECG features of TC in comparison to ECG features of anterior STEMI in a cohort of Pakistani population. Methodology: A retrospective analysis of first presentation ECG’s of 32 TC patients admitted in AKUH from January 2010 to December 2019 was done. TC was diagnosed using the Mayo clinic diagnostic criteria. Major exclusion criteria were patients with ECG features of left or right bundle branch block and left ventricular hypertrophy were excluded. Similar number of acute anterior STEMI patients (coronary angiogram proven) was identified and first presentation ECG features evaluated. 6 different ECG criteria to differentiate between TC and acute anterior STEMI were examined for diagnostic accuracy. Results: Patients with TC were younger and 81% of the patients were females .50% of the TC patients had precordial ST elevation >1.5mm. Reciprocal ECG changes were significantly lesser in the TC patients. The QTc interval was prolonged (>440msec) in 62.5% of the TC patients (20 patients) with a mean QTc of 456 +/- 48 msec. Q waves was seen lesser in TC patients (15.6 % vs 43.4%). All the ECG criteria examined for diagnostic accuracy for differentiating between TC and anterior STEMI had low sensitivity and high specificity. The highest sensitivity was 66 % for the criteria STe V2<1.75 mm and STe V3<2.5 mm in our population. Conclusion: This study demonstrates that published ECG criteria to distinguish TC from acute, anterior STEMI in Pakistani patients have a low diagnostic accuracy. Our study also shows that ECG of TC patients have lesser reciprocal ECG changes & Q waves, and longer QTc intervals. Novel ECG criteria amalgamating these findings can be developed to improve the accuracy of ECG diagnosis of TC.

Este artigo visa descrever de maneira fenomenológica a experiência de escuta musical com dispositivos portáteis, tendo como referência principalmente os estudos de Michel Chion e os conceitos filosóficos de Gilles Deleuze. A capacidade que esses aparelhos têm de proporcionar uma escuta em movimento faz com que eles sejam potenciais fontes de um efeito cinematográfico de suspensão ou de fabulação, em que a própria realidade torna-se tela panorâmica de uma obra processual e assubjetiva. O corpo ganha funções de mediação na medida em que o modo de auralidade dos dispositivos de escuta portátil, completamente autônomo, insere na percepção visual eflúvios sonoros, os quais, anexados ao ritmo do movimento imagético, elevam-no à posição de movimento cinemático, ou seja, de realidade que dura, de mais-que-realidade.

The profile of the electric field on the earth discontinuity with a lightning conductor
Authors: Khechekhouche Ali
Published: August 2020

In this paper, we present some results of investigations carried out in the electric field distribution of both horizontal and vertical lightning conductors in the case of discontinuous earth. The conductors may be situated as well as in the upper or the lower earth part. The electric field distribution was determined in the case of lightning conductor situated between the high voltage rod and the discontinuity (interface) and also in the case of high voltage rod situated between the lightning conductor and the discontinuity. In some situations the electric field distribution on the plan are smaller than defined by the electro-geometrical model. We attribute this result to the great field intensity at the discontinuity, which reduce the lightning conductor discharge capture effect. This is in concordance with the results concerning the electrical strength of such air gaps without lightning conductors.

Authors: Saoussane Gouiaa
Published: August 2020

The multi-copters are one of the important aircrafts in the world because they are used in both military and civil application. The problem of these aircrafts is the low efficiency of its propellers. That’s why, it is necessary to study the aerodynamic structure around every rotor. In this paper, a computer simulation has been done to study the aerodynamic structure around a NACA 6409 airfoil rotor. The numerical model is based on the resolution of the Navier-Stockes equations with a standard k-ε model. Then, the finite volume discretization of these equations leads to solve it. The local characteristics of the aerodynamic structure are extracted using the software Solidworks Flow Simulation and the validation is done with comparison with anterior result of Alexandrov (2013).

Municipality of El-Oued has been confronted with the phenomenon of the upwelling of water for several years and without almost any cease to become more extensive each year. This phenomenon took very alarming dimensions the last twenty years. The use of the deep layers water (the Continental intercalary and the Final Complex) in an excessive way considerably increased the volume of the water input, as well as the absence of a natural discharge system for the rejections of wastewater, are the principal causes of this ecological imbalance. Contributing to the deterioration of the palm trees, the inundation of (Ghouts) causes mortal consequences at the level of environment, agriculture, the economy and the health of Municipality of El-Oued.The piezometric variation of the water table has shown that in the areas of upwelling groundwater; correspond to piezometric depressions which has favored the accumulation and especially of the waste water.

Published: August 2020

This paper is an optical and thermal study of a small model of a parabolic trough solar collector (CTP), which will be used to heat tap water in the winter at Guemar, El-Oued province, Algeria. A mathematical model drawn from the energy balance equation applied to the absorber tube, this model was solved by the finite difference method. A computer program was developed to solve our problem. MATLAB was used as a tool for numerical simulation where it is used to calculate dynamic shifts at the level of the absorbent tube. The results are very honorable and encouraging, where the thermal efficiency of the concentrator had passed 61%, and the fluid temperature had passed 343 K.

Authors: Benabdelkrim Bouchra , Benatillah Ali
Published: August 2020

Photovoltaic modules operate under a large range of conditions. This combined with the fact that manufacturers provide electrical parameters at specific conditions (STC). The present study proposes a comparison between single and double diode models of solar PV system and ensures the best suited model under specific environmental condition for accurate performance prediction. An important feature of these models is that its parameters can be determined using data commonly provided by module manufacturers on their published datasheets. Accurate determination of these parameters which arose from a diversification of models and methods dedicated to their estimations is still a challenge for researchers. In this paper the single and two diode models have been studied by mathematical methods based on simulated Newton-Raphson iteration method. Newton-Raphson iteration method is solved by MATLAB simulation.

Published: August 2020

The purpose of this study was to analyze the Fluoride Tin Oxide (SnO2/F) production in home-scale industry in engineering point of view and economic evaluation perspective. This material is considered due to its wide range of energy-related applications. Evaluation of the SnO2/F production in engineering perspective is conducted from the selection of the most economical process, mass balance calculation, to the adaptation in the commercially available apparatuses. Evaluation of the production from the economic point of view is done by calculating economic parameters: Gross Profit Margin, Internal Rate Return, Payback Period, Cummulative Net Present Value, Profitability Index, and Breakeven Point. In short of the production process, we used the pure tin (as the metal precursor) and ammonium fluoride (as the source of Flouride for doping). The engineering point of view showed that the process is able to produce conductive glass that can be used as the active electrode substrate in the solar cell. Economic evaluation showed that the process is profitable, confirmed by the positive values from all economic parameters. However, for some cases that are compared to the market and the local bank interest, the process is not attractive for investor. Thus, to make them attractive, support from government or corporate social responsibility is required.
