Authors: Aboagye Emmanuel , Yawson Joseph Anthony , Appiah Kofi Nyantakyi
Published: July 2020

Problems associated with the transition from conventional learning (face to face) to online learning (e-learning) in the educational system are well documented. The present study explores the challenges students in tertiary institutions have reported facing in online learning in the era of coronavirus pandemic. Using a sample (n = 141), an initial principal component factor analysis was conducted to group the constructs. Eight groups that emerged were social issues, lecturer issues, accessibility issues, learner motivation, academic issues, generic issues, learner intentions, and demographics. Cronbach’s alpha was used to determine the reliability of the scales resulting in the deletion of learner motivation. Comparing the means of the factors revealed that the most important challenge for students to study online was accessibility issues. This was followed by social issues, lecturer issues, academic issues, and generic issues. The mean for the individual items in learners’ intention to study online showed that students were not ready to study online. A Multiple Regression Analysis was further conducted to determine which factors pose the most important challenges to the student’s decision to study online. Social issues and lecturer issues were significant. In the final model, only lecturer issues were significant. A blended approach-where conventional teaching is combined with online teaching should have ushered the learners to complete online learning.

Published: July 2020

The paper deals with destructive testing of �new� group of material - Wood Plastic Composite (in short WPC). WPC emerging from a fusion of two different kinds of components - thermoplastics matrix and natural reinforcement (fibres or flour). Natural fibres offer several advantages - they are renewable, inexpensive, low-density, good isolate a sound and low cost. These components are mixed under the influence of high temperature and then pressed to make various shapes. This material contains cracks localized on the interface between the wood and plastic. These cracks occurred due to inhomogeneity of WPC and affected mechanical properties of final WPC product. The testing of mechanical properties (tensile test and bending test) were determinate in VUHZ Dobra (Ostrava) - following the ISO standards. Significant differences between mechanical properties after testing were caused by non-perfect encapsulation between components and non-homogeneity of materials.

Published: July 2020

A good bone augmentation and regeneration depends essentially on the use of a high biomimetic hydroxyapatite, respectively of an osteoclast apoptosis promoting compound. The last one, used in oral or injectable form, leads to different gastrointestinal side effects. We suggested and studied, at non-clinical level, a composite of sodium alendronate linked on a biogene hydroxyapatite. The composite was obtained by putting an aqueous solution of alendronate into a suspension of hydroxyapatite in acetone. By physico-chemical methods the binding of alendronate (ALE) on hydroxyapatite was proved, the content of ALE in the composite being 22%. The patients can benefit from this composite due to a total elimination of gastrointestinal side effects as a consequence of limiting the bioactivity only locally.
Hydrolysis Mechanism of Bismuth in Chlorine Salt System Calculated by Density Functional Method
Authors: Chunfa Liao , Zhenxin Xu , Jianbai Zou , Pinguoo Jiang
Published: July 2020

Based on the density functional theory, this paper presents the calculated cellular electronic properties of BiCl3, BiOCl and Bi3O4Cl, including unit cell energy, band structure, total density of states, partial density of states, Mulliken population, overlapping population, etc. Combined with the thermodynamic analysis of Bi3+ hydrolysis process in chlorine salt system, the conversion mechanism of oxychloride bond in BiCl3 to form BiOCl and Bi3O4Cl by hydrolysis, ethanololysis and ethylene glycol alcohololysis was obtained by infrared spectroscopy. The results indicate that the energy of Bi3O4Cl cell system was lower than that of BiOCl cell, indicating that the structure of Bi3O4Cl was more stable. From the analysis of bond fluctuation, the electron nonlocality in BiOCl belt was relatively large, and the orbital expansibility was strong; thus the structure of BiOCl was relatively active. The state density map of Bi3O4Cl had the widest energy gap, i.e., the covalent bond between Bi3O4Cl was stronger than BiOCl. Therefore, the hydrolysis of BiCl3 would preferentially generate Bi3O4Cl with a more stable structure. The number of charge arrangement, overlapping population and infrared spectrogram indicate that there were two basic ways in the hydrolysis and alcoholysis of BiCl3. Firstly, two chlorine atoms in BiCl3 were replaced by hydroxyl groups ionized by water and alcohol to form [Bi(OH)2Cl] monomer, and BiOCl and Bi3O4Cl were formed by intra-molecular dehydration or inter-molecular dehydration. The other way was that the Bi atom directly reacted with the OH ionized by water and alcohol to form the [Bi-OH] monomer, and the Cl atom replaced the H atom on the hydroxyl group in the [Bi-OH] monomer to further form BiOCl and Bi3O4Cl.
The Biochemical Effects of Angiotensin-(1-7) on the Oxidative Stress Metabolism and Their Specific Parameters from the Temporal Lobe
Authors: Ungurianu Sorin , Trus Constantin , Enciu Roxana-Rosmary
Published: July 2020

It is already known from a variety of previous reports that an independent brain renin�angiotensin system (RAS) exists, completely separated from the one in the periphery. This independent brain RAS has all the precursors and the enzymatic structures necessary for the generation of the angiotensin peptides. Thus, in the last few years various groups started focusing on the more central effects of less known angiotensins (e.g in comparison with Angiotensin (Ang) II), namely Ang III, Ang IV, Ang-(1�7) or Ang 5-8. One of these newly emerging angiotensins which has become an increased center of interest in many studies is Ang-(1-7), which is a heptapeptide previously described especially for its opposite effects to Ang II, in the peripheral vascular area, but also described for some opposite central functions vs. Ang II. These aspects are completed with the fact that it was recently suggested that the renin�angiotensin system could modulate the oxidative stress metabolism, and also it seems that the manifestations of Angiotensin-(1-7) on the basal oxidative stress status are contradictory, with a variety of reports describing controversial (e.g. both pro-oxidant and antioxidant actions) effects for this heptapeptide. Our results presented here are confirming a possible antioxidant effect of Ang-(1�7) administration on rat, as shown by the increased levels of antioxidant enzymes from the temporal lobe (superoxide dismutase and glutathione peroxidase) and decreased levels of malondialdehyde, as an important lipid peroxidation parameter.

This study is based to a new concept, to use maize stalk for specific sorption and recovery of Cu(II) and Fe(III) from synthetic solutions. Thus, the sorption properties of the biomass resulting from the recycling of the maize stalk that reached maturity (autumn) were studied. In the first stage, the sorption properties of the maize stalk were evaluated in batch system. Moreover, in terms of water quality improvement several key parameters that influence the sorption equilibrium were evaluated. The effect of contact time (0-120min) and cations initial concentration (investigated range: 0.05-0.4 mg/L) on biomaterial sorption capacity were assessed. Kinetic studies were performed taking into consideration the initial concentration of metallic cation. The experimental data were analyzed based on first order kinetic model, pseudo-second-kinetic model and Morris Webber kinetic model. The kinetics of sorption was in accordance with the pseudo - second - kinetic model as the correlation coefficients showed (R2=0.9940 for Cu(II) and R2=0.9999 for Fe(III)). Moreover the desorption study was evaluated with hydrochloric acid and have detected to be 63% and 89% for Cu(II) and Fe(III) when 4M HCl is used. The surface of the maize stalk loaded with Cu(II) and Fe(III) was characterized by various specific techniques such as FTIR-ATR, SEM, and TG. Experimental results revealed that cations sorption process takes place on the sorbent surface. The sorption rate of each metallic cation is controlled by the formation of chemical bonds with surface polar groups. Their presence on biomass structure, evidenced by FTIR-ATR analysis, explains the behavior of maize stalk as a weak ion exchanger acid.

Antimicrobial resistance constitutes a topical subject and it is one of the major threats to public health. According to statistics, the incidence of multidrug-resistant microorganisms, such as bacteria, fungi and protozoa has increased in the last decades and it continues to spread. Therefore, the development of novel antimicrobial agents to combat drug-resistant infections is very important, among other research directions in this field. Quinoline ring is a very interesting structure for researchers because of its diverse biological properties (antimicrobial, anticancer, anticonvulsant, antiinflamatory and cardiovascular). On the other hand several studies showed good antibacterial activity (including anti-Pseudomonas effects) and antifungal properties of rutin or vegetal species with a high flavonoids (especially rutin) concentration. Based on the above considerations, eight novel rutin derivatives carrying 4- and 8-aminoquinoline moiety were designed, synthesized and characterized by FTIR, 1H NMR and elemental analysis. All compounds were evaluated for their in vitro antimicrobial activities against representative Gram-positive, Gram-negative and fungal pathogens. The results indicated that all rutin derivatives exhibited good antibacterial activities, similar to ciprofloxacin.
Big data analytics and international market selection: An exploratory study
Authors: Calof Jonathan , Viviers Wilma
Published: July 2020

A great deal of information is available on international trade flows and potential markets. Yet many exporters do not know how to identify, with adequate precision, those markets that hold the greatest potential. Even if they have access to relevant information, the sheer volume of information often makes the analytical process complex, time-consuming and costly. An additional challenge is that many exporters lack an appropriate decision-making methodology, which would enable them to adopt a systematic approach to choosing foreign markets. In this regard, big-data analytics can play a valuable role. This paper reports on the first two phases of a study aimed at exploring the impact of big-data analytics on international market selection decisions. The specific big-data analytics system used in the study was the TRADE-DSM (Decision Support Model) which, by screening large quantities of market information obtained from a range of sources identifies optimal product‒market combinations for a country, industry sector or company. Interviews conducted with TRADE-DSM users as well as decision-makers found that big-data analytics (using the TRADE-DSM model) did impact international market-decision. A case study reported on in this paper noted that TRADE-DSM was a very important information source used for making the company’s international market selection decision. Other interviewees reported that TRADE-DSM identified countries (that were eventually selected) that the decision-makers had not previously considered. The degree of acceptance of the TRADE-DSM results appeared to be influenced by TRADE-DSM user factors (for example their relationship with the decision-maker and knowledge of the organization), decision-maker factors (for example their experience and knowledge making international market selection decisions) and organizational factors (for example senior managements’ commitment to big data and analytics). Drawing on the insights gained in the study, we developed a multi-phase, big-data analytics model for international market selection.
Intelligent information extraction from scholarly document databases
Authors: Fernandez Fernando Vegas
Published: July 2020

Extracting knowledge from big document databases has long been a challenge. Most researchers do a literature review and manage their document databases with tools that just provide a bibliography and when retrieving information (a list of concepts and ideas), there is a severe lack of functionality. Researchers do need to extract specific information from their scholarly document databases depending on their predefined breakdown structure. Those databases usually contain a few hundred documents, information requirements are distinct in each research project, and technique algorithms are not always the answer. As most retrieving and information extraction algorithms require manual training, supervision, and tuning, it could be shorter and more efficient to do it by hand and dedicate time and effort to perform an effective semantic search list definition that is the key to obtain the desired results. A robust relative importance index definition is the final step to obtain a ranked importance concept list that will be helpful both to measure trends and to find a quick path to the most appropriate paper in each case.

Background: The subject of this research is the creation of an optimal school bench design with the aim of determining the most favorable posture of students while sitting, taking into account the relevant ergonometric and biomechanical characteristics of the human body. For the proposed model of the school bench which allows adjusting the different slopes of its surface, the corresponding computer model of the student and the table was first created, and then biomechanical and RULA analysis was performed in order to determine the maximum load in the lumbar part. Next, for each test subject of given weight, it was necessary to determine the amount of maximum load in lumbar zone L3/L4 for different slope angles and to determine the critical angles at which the maximum permissible load of 3400 N is reached.

Methods: The analysis is performed on a total of 5 subjects of the same height (180 cm) and various weights (60, 70, 80, 90, 100 kg). The task is to determine at which weight and at what angle of the workbench with standard height will not exceed the permissible loads of the spine, specifically referring to the L4/L5 vertebrae whose stresses should not exceed 3400 N. The CATIA software package (Dassault Systèmes, Vélizy-Villacoublay, France) is used for the analysis. By knowing the anthropometric and work environment data with ergonomic design and analysis, the following analyzes were made: biomechanical analysis, rapid upper limb assessment (RULA) and carry analysis (an option from CATIA software).

Results: The proposed school bench design allows for flexible adjustments to its worktop, that is, changing its tilt. This allows students of different body masses to have an optimal position at work that does not compromise their maximum permissible load in the L4/L5 spinal column (3400N).

Conclusions: The proposed ergonomic design of the desk will result in students being adequately positioned during their activities at school with the minimal risk of permanent deviations and other health problems.

In this paper, a new compact coplanar antenna used for Radio frequency identification (FID) applications is presented. This antenna is operated at the resonant frequency of 2.45 GHz. The proposed antenna is designed on an epoxy substrate material type (FR-4) with small size of (40 × 28) mm2 in which the dielectric thickness (ℎ) of 1.6 mm, relative permittivity (er) of 4.3 and tangent loss of 0.025. In this design the return loss is less than −10 dB in the frequency interval (2.12 − 2.84) GHz and the minimum value of return loss is -32 dB at resonant frequency. The maximum gain of the proposed antenna is 1.22 dB and the maximum directivity obtained is 2.27 dB. The patch and the ground plane of the proposed antenna are in the same surface. The proposed antenna has a wide bandwidth and omnidirectional radiation pattern with small size. The overall size of the compact antenna is (40 × 28 × 1.635) mm3. The Computer Simulation Technology (CST) microwave studio software is used for simulation and gets layout design.

Authors: Abdulhussein Nabil , Abdullah Abdulkareem
Published: July 2020

This paper presents a new design to obtain wide dual-band operation from a coplanar probe feed antenna loaded with two shorted walls. The lower band of proposed antenna has a 10 dB bandwidth of 611 MHz (24.18%) around the center frequency 2527MHz, and the upper band has a bandwidth of 1255 MHz (27.88%) around the center frequency 4501MHz. The obtained bandwidths cover WLANs operations on all bands. The bandwidth of the first operating frequency covers ISM band (2400-2483.5) MHz, which is required by IEEE 802.11b, g and Bluetooth standards, and the bandwidth of the second operating frequency covers U-NII1 (5150-5350) MHz band, which is required by IEEE 802.11a and HiperLAN2 standards, and also covers U-NII2 (5470-5725) MHz and U-NII3/ISM (5725-5825) MHz bands, which are required by IEEE 802.11a standard. A three dimensional finite-difference time-domain (3-D FDTD) method is employed to analyze the proposed structure and find its performance. The simulated results are compared with the experimental results.

A robot is a smart machine that can help people in their daily lives and keep everyone safe. the three general sequences to accomplish any robot task is mapping the environment, the localization, and the navigation (path planning with obstacle avoidance). Since the goal of the robot is to reach its target without colliding, the most important and challenging task of the mobile robot is the navigation. In this paper, the robot navigation problem is solved by proposed two algorithms using low-cost IR receiver sensors arranged as an array, and a robot has been equipped with one IR transmitter. Firstly, the shortest orientation algorithm is proposed, the robot direction is corrected at each step of movement depending on the angle calculation. secondly, an Active orientation algorithm is presented to solve the weakness in the preceding algorithm. A chain of the active sensors in the environment within the sensing range of the virtual path is activated to be scan through the robot movement. In each algorithm, the initial position of the robot is detected using the modified binary search algorithm, various stages are used to avoid obstacles through suitable equations focusing on finding the shortest and the safer path of the robot. Simulation results with multi-resolution environment explained the efficiency of the algorithms, they are compatible with the designed environment, it provides safe movements (without hitting obstacles) and a good system control performance. A Comparison table is also provided.
Two Algorithms For Static Polygon Shape Formation Control
Authors: Issa Bayadir , Rashid Abdulmuttalib
Published: July 2020

This paper provides a two algorithms for designing robust formation control of multiple robots called Leader- Neighbor algorithm and Neighbor-Leader algorithm in unknown environment. The main function of the robot group is to use the RP lidar sensor attached to each robot to form a static geometric polygon. The algorithms consist of two phases implemented to investigate the formation of polygon shape. In the leading- neighbor algorithm, the first stage is the leader alignment and the adjacent alignment is the second stage. The first step uses the information gathered by the main RP Lidar sensor to determine and compute the direction of each adjacent robot. The adjacent RP Lidar sensors are used to align the adjacent robots of the leader by transferring these adjacent robots to the leader. By performing this stage, the neighboring robots will be far from the leader. The second stage uses the information gathered by adjacent RP sensors to reposition the robots so that the distance between them is equal. On the other hand, in the neighbor-leader algorithm, the adjacent robots are rearranged in a regular distribution by moving in a circular path around the leader, with equal angles between each of the two neighbor robots. A new distribution will be generated in this paper by using one leader and four adjacent robots to approve the suggested leader neighbor algorithm and neighbor-leader algorithm.

Background: The management of children with type 1 diabetes mellitus (T1DM) remains a major challenge in developing countries.
Case presentation: We report an adolescent male who was diagnosed with T1DM at the age of 11 years when he presented at a private hospital with diabetic ketoacidosis. He received emergency treatment there and was subsequently referred to our tertiary hospital for expert care. All through the management, there was poor clinic attendance, poor glucose monitoring, poor compliance with insulin therapy, and ultimately, poorly controlled diabetes. Later, he developed diabetic autonomic neuropathy which manifested as unawareness of bladder fullness with secondary enuresis and fecal incontinence. He was also severely malnourished. At his last admission, seven years after the initial diagnosis, he presented with burnt hands and feet, which were injuries sustained from putting his extremities in naked flames when he lapsed into a coma during a religious activity. He received multidisciplinary management but died a few weeks later.
Discussion and conclusion: This case is being reported to draw attention to the plight of children with T1DM from the low socioeconomic class in developing countries. In such children, poverty and ignorance may have profound negative effects on the management and outcome of T1DM.
Belo Horizonte, a cidade modelar: representações da nova capital das Minas Gerais
Authors: Othon Teixeira Alves Rogério
Published: July 2020

Ao se fundar a moderna cidade de Belo Horizonte em 1897, a sua dinâmica revelaria significados que extrapolariam a prancheta dos engenheiros. Com o tempo, aspectos políticos e sociais que forjariam aquela sociedade seriam trazidos nos periódicos da época da nova capital. Quais os sentimentos primários ao se pensar na nova cidade? Havia ideais políticos nela embutidos? Quais as reações e tensões refletidas da antiga capital, Ouro Preto? Quem foram os primeiros belo-horizontinos? Este trabalho buscou em periódicos mineiros, informações que demonstrassem a ideia da construção na nova capital e os desdobramentos decorridos da nova sociedade. A fundação da cidade refletiria supostamente o moderno, o civilizado, o urbano, em contraposição à antiga e atrasada Ouro Preto monarquista. Pelos periódicos e autores consultados, percebeu-se que na mudança de endereço da capital não havia intuito de se negligenciar o orgulho do povo mineiro, depositado nas ideias libertárias dos personagens independentistas da Ouro Preto oitocentista. Se, em princípio, no reino ideológico o objetivo foi sepultar a antiga Ouro Preto embaixo da arrojada Belo Horizonte, na prática, o sujeito que se formava na nova capital, orgulhou-se da grandiosa moderna cidade sem desmerecer o passado, a tradição e a história da antiga.
