Authors: Ali Rashid
Published: December 2020

This research analyzes the design and simulation of a mobile robot using Extended Kalman Filter (EKF) and Unscented Kalman filter (UKF). The mobile platform has a differential configuration, where each track of a wheel is associated with an encoder. The EKF and UKF methods are used to integrate the measurements of a novel odometric system based on the optical mice and the measurements of a localization system based on a map of geometric beacons. Two different types of simulations have been performed for validating the results, either using the mouse-based odometric system or using the conventional wheel encoder-based odometric system, to compare and evaluate the errors made by each system.
INTEGRATED IoT BASED WATER QUALITY AND QUANTITY MONITORING SYSTEM
Authors: Arsalan Muhammad
Published: December 2020

Smart and cost-effective solutions for water quality monitoring are gaining attention with the recent advancement in information and communication system technology. This paper aims at the design and development of the internet of things (IoT) based low-cost and portable water quality and quantity monitoring (WQQM) system. The proposed system not only monitors the water quality but also monitors the amount of water being utilized by the consumer. The main objective of designing WQQM is to ensure both purity and conservation of water. The water quality meter measures six qualitative parameters of water viz. potential hydrogen (pH), water temperature, atmospheric temperature, turbidity, and total dissolved solids (TDS). Whereas, the water quantity meter measures the water level and water flow to calculate the amount of water being used. A custom printed circuit board (PCB) is designed to integrate all the sensors for quality and quantity measurement. The results generated by the WQQM system are wirelessly transferred, using Wi-Fi, to the online monitoring system.
A NEW AND EFFICIENT SIMPSON’S 1/3-TYPE QUADRATURE RULE FOR RIEMANN-STIELTJES INTEGRAL
Authors: Memon Kashif
Published: December 2020

In this research paper, a new derivative-free Simpson 1/3-type quadrature scheme has been proposed for the approximation of the Riemann-Stieltjes integral (RSI). The composite form of the proposed scheme on the RSI has been derived using the concept of precision. The theorems concerning basic form, composite form, local and global errors of the new scheme have been proved theoretically. For the trivial case of the integrator in the proposed RS scheme, successful reduction to the corresponding Riemann scheme is proved. The performance of the proposed scheme has been tested by numerical experiments using MATLAB on some test problems of RS integrals from literature against some existing schemes. The computational cost, the order of accuracy and average CPU times (in seconds) of the discussed rules have been computed to demonstrate cost-effectiveness, time-efficiency and rapid convergence of the proposed scheme under similar conditions.

Aplicación del método de la deliberación de Gracia en líderes religiosos que asisten espiritualmente a mujeres privadas de la libertad
Authors: Quintero Quiroga Giovanny
Published: December 2020

El presente artículo pretende profundizar en la aplicación del método de la deliberación en un contexto de líderes religiosos, con el fin de que sea una herramienta útil para poder resolver las dificultades que surgen en la asistencia espiritual que se brinda a mujeres privadas de la libertad. Para realizar este cometido, me apoyo en el pensamiento de Gracia (2011a; 2011b; 2014) con su propuesta de la pedagogía deliberativa. La tarea de destacar el método deliberativo y aplicarlo en dicho contexto hace que se unifiquen criterios en la implementación de fundamentar y orientar la asistencia espiritual para personas de diferentes creencias religiosas. Dedicarnos a llegar a acuerdos por el ejercicio deliberativo es el compromiso que tenemos los líderes religiosos en un contexto penitenciario femenino. Así mismo, priorizar los elementos valiosos que fundamentan y sostienen la vida espiritual de las mujeres hace que su contexto esté lleno de esperanza y su proyecto de vida adquiera más sentido. El tema de la espiritualidad, al ser complejo por las variables que presenta, no impide a líderes religiosos reflexionar sobre los elementos propios de la deliberación, por el contrario, ayuda para que la vida espiritual de las mujeres, en su condición de encierro, pueda seguir descubriendo lo que es voluntad de Dios mientras que recobran su libertad física.

Authors: Svane Jeff Kirk , Konge Lars , Tønnesen Hanne
Published: December 2020

Background Implementation in healthcare is often slow and poorly reported. Results include suboptimal outcomes and adverse consequences for patients. However, promising tools to remedy implementation speed and reporting already exist – such as the evidence-based, fast-track implementation model (Fast-IM) and the comprehensive RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) reporting format. Metods In combination, Fast-IM and RE-AIM may constitute a new best practice for fast and well-reported implementation. The aim of this article was to visualize the feasibility of the combination in practice via 3 examples concerning smoking cessation among patients, simulation-based training of healthcare professionals, and mandatory regulation. Results Combining Fast-IM and RE-AIM is feasible and provides a useful overview of both implementation process and results. Conclusion This article describes a new best practice for fast and well-reported implementation by combining Fast-IM and RE-AIM.

Authors: DEĞİRMENCİ Hakan
Published: December 2020

Türk edebiyatında İstanbul’un fethini ele alan romanların geçmişi, Türk romanının mazisi kadar eskidir. İlki 1875’de yayımlanan Süleyman Musli romanıyla başlayan fetih romancılığı, Tanzimat ve II. Meşrutiyet dönemlerinde devam etmiş, Cumhuriyet’ten itibaren Tek Parti, Demokrat Parti dönemlerinde de ele alınmış ve 1970’lardan itibaren gayet nitelikli ürünlerle zirveye çıkmıştır. 2000’lerden itibaren ilkede yaşanan siyasal ve toplumsal dönüşüme paralel olarak fethe duyulan alakayı para kazanma aracı olarak gören bir zümre de oluşmuş ve ortaya piyasa romanı olarak nitelendirebileceğimiz ürünler de çıkmıştır. Nihayetinde fetih meselesi, hangi dikkat ve malumat seviyesinde olursa olsun, herkesin ilgisini çeken popüler bir konudur.

Bu çalışmada, kurgusal metinlere yansıyan yönüyle hem Osmanlı Devleti ve toplumu bakımından hem de Bizans Devleti ve genel olarak Hristiyan dünyası bakımından fethin öncesine yönelik değerlendirmeler yapılacaktır. Surların her iki tarafında yaşanan siyasi, askerî ve ekonomik koşular ve bunların insani ve sosyolojik süreçler bağlamında romanlara yansımasıyla ilgili tahliller, fethe giden süreci daha iyi anlamamıza vesile olacaktır.

Authors: PAMUK ÖZTÜRK Nuray
Published: December 2020

Çin toprakları tarih boyunca birçok hanedanlığa ev sahipliği yapmıştır. Bu hanedanlıklardan bir tanesi de Tang Hanedanlığıdır (618-906). Tang Hanedanlığının kurulması ile Çin’de yeni bir dönem başlamıştır. Bu dönemde siyasi, ekonomik, sosyal ve kültürel alanda birçok gelişme yaşanmıştır. Kültürel alanda yaşanan gelişmelerin içerisinde edebiyat önemli bir yere sahiptir. Bu dönem, Çin edebiyatının gelişmesinde ve yenilenmesinde bir dönüm noktası niteliğindedir. Tang Hanedanlığı döneminde ortaya çıkarılan edebiyat eserleri, günümüz Çin edebiyat eserlerinin temelinin oluşmasında büyük etkiye sahiptir. Sanat ve edebiyata önem veren imparatorların desteği ile gelişen Tang dönemi edebiyatında en göze çarpan öğelerden biri şiirdir. Daha önceki dönemlerde şairler tarafından imparatora ve saraya övgüler sunan şiirler yazılırken, Tang Hanedanlığı döneminde şiirlerde genel olarak; halkın durumu, doğa olayları, sosyal yaşam, savaşlar, kahramanlıklar, sevgi gibi konular ele alınmıştır. Şiirler yapısal olarak beş veya yedi im kullanılarak yazılmıştır. Her bir Çince karakter Türkçede “im” olarak ifade edilmektedir. Günümüzde Tang dönemi Çin şiiri “en az im ile en fazla olanı anlatma sanatı” olarak nitelendirilmektedir. Bu çalışmada Tang Hanedanlığı döneminin Beş İmli Dört Mısralı Şiir türünün özelliklerinden, şair Wang Wei (701-761) ve Meng Haoran’ın (689-740) hayatlarından bahsedilmiştir. Şairlerin beş im’li dört mısralı şiirlerine örnekler verilmiştir. Şiirlerin Türkçe anlatıma en uygun şekilde çevirileri yapılmış olup, konuları hakkında inceleme yapılmıştır.

Published: December 2020

Nano Spinel Lithium Manganese Oxide (LiMn2O4) was distributed properly on carbon nanotubes ( CNTs) and graphene nanoplatelets (GNPs) using chemical coprecipitation method. The original particle size was less than 40 nm, and the average size of the crystallite was 20 nm without the application of any capping agents. Characteristic spectra of spinel structure and a peak of CNTs & GNPs obtained using X-ray powder diffraction (XRD). CNTs and GNPs in energy storage systems improve the rate capabilities and cyclic efficiency of cathode materials. The suggested technique, chemical coprecipitation, provides new avenues for the production of nano-sized lithium transition metal oxide composites with CNTs and GNPs in an inexpensive and simple way. Higher density energy storage systems raise significant safety issues, and for safety, they are restricted to 30 percent to 50 percent of their ability. The proposed composite would enable the energy storage systems to be used even at high temperatures and higher discharge rates above 60 percent of their ability. Besides, the parasitic reaction between the electrode surface and the electrolyte will decrease, which will increase the battery's projected life span. As an all-solid-state device, the new composite batteries would make the system non-flammable, immune from side reactions, and resistant to capacity erosion.

Published: December 2020

Lithium ion batteries (LIBs) are attractive for energy storage application. In this regard, lithium rich layered oxides (LLOs), are considered viable cathodes due to their tempting properties such as lower production cost, faster manufacturing process, excellent reversible capacity, and better electrochemical performance at high voltages. Despite these properties, LLOs lack in cyclic stability and inferior capacity retention. This study proposes a surface modification technique to overcome the above-mentioned limitations in which a layer of silica (SiO2) has been coated on the particles of Li1.2Ni0.13Mn0.54Co0.13O2. The Li1.2Ni0.13Mn0.54Co0.13O2 was synthesized by a sol-gel process and then coated with SiO2 (SiO2=1.0 wt. %, 1.5 wt. %, and 2.0 wt. %). The coatings were undertaken through a dry ball milling technique. Different characterization test such as X-Ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), elemental mapping, and X-ray photoelectron spectroscopy (XPS), were utilized to prove phase pure material formation and identify the SiO2 layer on the surface of Li1.2Ni0.13Mn0.54Co0.13O2. The electrochemical measurements, confirm the improvement in capacity retention and cyclability of SiO2 coated Li1.2Ni0.13Mn0.54Co0.13O2 samples with reference to the uncoated samples. This improvement can be ascribed to the protective and barrier effect of the coated layer on the LLOs particles avoiding any unwanted side reactions when the cathode is exposed to the electrolyte. A small trade-off between electrochemical performances and the coating thickness confirms the best efficiency of 1 wt.% SiO2 coated Li1.2Ni0.13Mn0.54Co0.13O2 when compared to other coated samples.
Organic Pollutants along the Qatari Coast: A Case Study of the Pearl Oyster (Pinctada radiata)
Authors: AlShamary Noora Mahmood AlJathelah , Mondal Debapriya , Simon Hutchinson
Published: December 2020

The Qatari marine environment is endangered due to high industrial expansion and anthropogenic pressure over the last few decades. The presence of common contaminants such as total petroleum hydrocarbons (TPHs) and polycyclic aromatic hydrocarbons (PAHs) is a threat to the marine environment. The aim of this study is to determine the environmental threats and risks posed by organic contaminants to Qatar’s marine environment using pearl oyster ‘Pinctada Radiata’ as the indicator study organism. The samples (marine sediment, seawater, and oysters) were collected four times within two years in different seasons from the four sites (Simaisma, Al Khor, Umm Bab, and Al Wakra), on March 2017, December 2017, May 2018, and November 2018. A total of 144 samples were analyzed, 48 samples of seawater, 48 samples of sediment and 48 samples of oysters. Levels of organic contaminants (TPHs and PAHs) were quantified in seawater, marine sediment and oyster tissues (P. radiata). In addition, the TOC and particle sizes were measured in abiotic matrices as well as the temperature, salinity, and pH of seawater in the study areas. Overall, the organic contaminants (TPHs and PAHs) were more readily detected in oyster tissue samples than marine sediment and seawater samples collected from the same areas. The surface seawater samples showed negligible levels of PAHs, while TPHs were ranged from 1.164 to 271.77 μg/L. The concentration of TPHs and PAHs in surface marine sediment were ranged between (75.02 -1751.82) and (4.25 - 36.73) μg/kg dry weight respectively. In oyster tissue samples, the level of TPHs was ranged from 633.33 to 6666.67 μg/kg dry weight, with the highest concentrations measured in Simaisma, while PAHs concentration showed an extreme variation from 25.90 to 2244.03μg/kg dry weight. The present study could, however, provide useful background information for further investigations to understand the presence of organic contaminants in Qatar’s marine environment.

Published: December 2020

PANI coated Cu-ZnS porous microsphere structures have been synthesized by hydrothermal method and in-situ polymerization process. The synthesized composite is characterized by different techniques in order to study the structural, morphological and surface absorption properties. The experimental observation demonstrates that the PANI/1%Cu-ZnS composite has better sensitivity, fast response and good stability as compared to pure PANI and other PANI/CuZnS compositions. Finally, PANI/1% Cu-ZnS composite has been found to be optimized for the humidity sensors due to its well-distributed roughness, porosity and hydrophilicity. The average response and recovery times of the PANI/1% Cu-ZnS are found to be 42 s and 24 s, respectively, which outperform recent results.

Authors: khan Shoyeb , Das Probir , Abdul Quadir Mohammed , Thaher Mahmoud , Al Jabri Hareb
Published: December 2020

Chroococcidiopsis sp. was grown in 200 L open raceway pond. Biomass density and average biomass productivity were 0.41 g/L and 16.1 g/m2/d. Chroococcidiopsis biomass was harvested by self-settling. Self settled biomass was further subjected to centrifugation to obtain a biomass paste with 25-30% solid content. Centrifuged biomass was dried at 80 °C overnight and used as a feedstock for pretreatment step. Biomass was pretreated in water at 105 °C for 15 minutes. A slurry containing 15 wt% pretreated and untreated biomass (control) in deionized water was prepared and subjected to hydrothermal liquefaction for biocrude oil production. Hydrothermal liquefaction for both pretreated and untreated biomass was conducted at temperatures ranging from (275, 300, 325, 350 °C) in a 500 mL high-pressure PARR reactor for 30-minute reaction holding time. Maximum biocrude yields for pretreated and untreated biomass was 42.4 % and 26.4 % based on ash free dry weight basis. Biocrude oil was characterized for hydrocarbons using GC-MS technique. Biocrude oil obtained from pretreated and untreated biomass contained 58.9% and 41.01% (C8-C19) hydrocarbons. Higher heating values for biomass and biocrude oil were 16.93 and 31.28 MJ/kg, with an energy recovery value of 41.1%.
Novel Approach to Study the Diversity of Soil Microbial Communities in Qatar
Authors: Oja Jane , Adenan Sakeenah , Talaat Abdel-Fattah , Alatalo Juha
Published: December 2020

A broad diversity of microorganisms can be found in soil, where they are essential for nutrient cycling and energy transfer. Recent high-throughput sequencing methods have greatly advanced our knowledge about how soil, climate and vegetation variables structure the composition of microbial communities in many world regions. However, we are lacking information from several regions in the world, e.g. Middle-East. We have collected soil from 19 different habitat types for studying the diversity and composition of soil microbial communities (both fungi and bacteria) in Qatar and determining which edaphic parameters exert the strongest influences on these communities. Preliminary results indicate that in overall bacteria are more abundant in soil than fungi and few sites have notably higher abundance of these microbes. In addition, we have detected some soil patameters, which tend to have reduced the overall fungal abundance and enhanced the presence of arbuscular mycorrhizal fungi and N-fixing bacteria. More detailed information on the diversity and composition of soil microbial communities is expected from the high-throughput sequenced data.

Published: December 2020

Sida cordifolia L. (SC) is an invading species that represents a threat to grazing lands in Niger. In order to enhance this invasive species, we studied the use of this plant for compost-making. First, the study evaluated the development of chemical properties under aerobic composting of SC in pit (P) and in heap (H) composting with two different mixtures. Mixture 1 (M1) contained 75% SC, 20% manure and 5% ash, while mixture 2 (M2) contained 95% SC and 5% manure. Then, the phytotoxicity test of the composts obtained was carried out by evaluating the effects of four different concentrations of compost on germination of pearl millet. The study of the effect of the rates 1000 kg ha-1 and 1500 kg ha-1 (100g and 150 g hill-1) of the different composts on pearl millet yield under field conditions. The composting was undertaken at Molli fishery station and the agronomic tests at the N’Dounga experimental site during two seasons (2018 and 2019). The chemical analysis showed that the composts from M1 were richer in plant nutrients than the M2 composts. All four rates of composts gave germination rates beyond 50% independent of composting method or compost mixture. On both seasons, the 1000 kg ha-1 M1P gave the best result in terms of grain yield. In 2018, M1P treatment increased grain yield compared to the control by 652 kg ha-1 (105.2%), while in 2019, the corresponding yield increase was 812 kg ha-1 (118.02%). Application of 1000 kg M1 compost ha-1 corresponded to about 11.1 kg N ha-1, which is more than three times the amount of N applied when using the recommended rate of 20 kg NPK ha-1 as micro dosing. This result showed that compost of SC can be used as a supplement to mineral fertilizer for increasing pearl millet yield.
On the Legitimacy of Cross-Border Pharmacy
Authors: Rabinovitch Simon R.
Published: December 2020

Cross-border pharmacy sales of prescription drugs to U.S. patients by Canadian Internet pharmacies have generated significant controversy in the U.S. and Canada. Violative of U.S. legislation and Canadian professional codes of conduct, cross-border pharmacy has nonetheless flourished in response to strong demand and incomplete enforcement. Proponents laud the greater affordability of needed drugs provided by cross-border pharmacy; opponents decry the practice as unsafe, economically ill-advised and harmful to Canadian interests in the long term.

This article evaluates the safety arguments that have been put forward by the U.S. Food and Drug Administration and others and concludes that they do not justify a prohibition on prescription drug imports from Canada. Similarly. Canadian professional regulatory bodies' objections to the participation of Canadian pharmacists and physicians in cross-border dispensing are a misapplication of conduct rules developed in another context. Objections to cross-border drug sates based on an economic analysis assume normative positions that should be explicitly identified and socially determined. On the other hand, if patient safety, professional responsibility and economic arguments fail to provide adequate support for a policy of prohibition, then self-interest in protecting domestic drug supplies and prices may support, at least from a Canadian perspective, some constraints on cross-border pharmacy.
The Origins, Early History and Evolution of the English Criminal Trial Jury
Authors: Anand Sanjeev
Published: December 2020

This article presents an historical account of the English criminal trial jury from its birth in the thirteenth century, as a largely self-informing institution that replaced the ordeals, to the nineteenth century, where the passivity of the modern trial jury became firmly established as a result of the influence of legal counsel and the development of the adversarial criminal trial. The expansive timeline that is assessed reveals that public distrust of the motives and competency of jurors is a recurrent theme and not simply a modern phenomenon. However, the historical evidence suggests that criminal trial jurors tended not to suffer from the deficiencies attributed to them by some commentators. Because the jury has undergone significant transformations in the past and survived, modern day proponents of the criminal trial jury could argue that it is capable of continuing to accommodate significant changes to the practices that govern its conduct. For those inclined towards the reform of the English criminal trial jury, some of the features noted by the author that have been discarded over time may be considered deserving of revival.

In recent years, substantial attention has been given to the impact of Financial Participation on Financial Performance. However, there is a lack of research of the impact of Financial Performance on Financial Participation and the mediating role of Fnancial Participation between Financial Performance, Employee Recruitment and Employee Retention. In this paper, Financial Performance, Financial Participation, Employee Recruitment and Employee Retention is examined, including two types of financial participation; Employee Stock Options and Profit Sharing. The purpose of this research was to understand the role of financial participation in attracting individuals and retaining them. Non-probability-based convenience sampling technique was used in this study. The technique was used mainly due to ease of access of respondents, geographical proximity and cost-effectiveness (Etikan et al. 2016). Structural Equation Modelling was applied on the data analysis using Partial Least Squares method on SMART-PLS Software. Drawing on the data collected from 211 respondents from various national and multinational companies in the FMCG Sector of Karachi, Pakistan. The results indicated that Financial Participation has important interaction effects with Financial Performance, Employee Recruitment and Employee Retention. It is also found that indirect effect of Financial Participation has a strong mediating relationship with Employee Retention as compared to Employee Recruitment. The findings suggest that by incorporating financial participation by employees, HR can effectively recruit and retain better individuals. Also, ESOPs are a better form of attracting and retaining better employees.

Objetivo: este estudio tuvo como propósito, determinar la existencia de una asociación entre el índice de masa corporal y la regulación cardiovascular en estudiantes de medicina. Materiales y métodos: Estudio transversal con un diseño aleatorio. La muestra se compuso por 54 estudiantes de medicina (21,2 ± 1,6 años) que fueron evaluados y clasificados según el índice de masa corporal: Normopeso (NP; IMC < 25 kg/m2); Sobrepeso (SP; IMC≥ 25 kg/m2); Obesos (OB; IMC a 30 Kg/m2). Medidas antropométricas, presión arterial y variabilidad de frecuencia cardiaca (HRV) fueron las variables evaluadas. Resultados: 51,9% de los estudiantes presenta sobrepeso u obesidad. El índice de masa corporal correlaciona negativamente con el parámetro de variabilidad de frecuencia cardíaca, especialmente al compararla en los dominios de tiempo de HRV (p<0,001). También se observaron diferencias en el control autonómico cardíaco al comparar los grupos de estudio en LnRMSSD (p<0,01) y LnSDNN (p<0,01). Conclusión: los estudiantes de medicina que presentan mayor índice de masa corporal se asocian a un menor control autonómico cardíaco y menor acción parasimpática en la regulación del sistema cardiovascular.
