The Quest For Equal Citizenship: Middle Eastern Christian Narratives of Migration and Inclusion in the United Kingdom
Authors: Hunter Alistair , McCallum Guiney Fiona
Published: December 2020

This article explores how migrants experience the process of becoming (and being) citizens by taking the understudied case of Middle Eastern Christians of Iraqi and Egyptian heritage residing in the United Kingdom. It is argued that exclusion in the Middle East reinforces a sense of inclusion in the UK particularly due to the prevalence of the rule of law in the UK. However, by exploring a “clash of values” on the role of religion in society and sexual liberalization issues, it is suggested that Middle Eastern Christians’ support for equality and tolerance is not absolute, especially when they perceive societal norms as conflicting with religious teachings. Finally, the paper shows how the notion of “protective patriotism” is used by some Middle Eastern Christians to express their belonging to their new state by defending perceived societal values.

Published: December 2020

The subject of this research is the analysis of possible implementation of the mechanisms of functionality of human immune system applicable to information security systems in automated data processing systems. The objects of this research are the human immune system, information security systems, and automated data processing systems. The research is conducted on the basis of achievements of systemic-conceptual approach towards information protection in automated data processing systems, developed within the framework of the project sponsored by the Russian Foundation for Basic Research No. 19-01-00383 on creation of intelligent information protection systems based on the neural network intrusion detection systems and  the mechanisms of artificial immune systems. The article reviews similarity and difference between human immune system and information security systems. Special attention is given to identification of peculiarities of functionality of the mechanisms on detection of harmful intrusions into these systems respectively. Methodological research on the topic are carried out using the achievements in the area of creation of neural network intrusion detection system, built on the basis of artificial immune mechanisms that function similar to human immune system. The main result consists in the conclusion that adaptive information security systems containing the means and mechanisms of protection and built by analogy with the human immune system, may provide successful and effective protection of information in automated data processing systems. The specificity and importance of this conclusion is substantiated by the fact that it can be implemented despite the absence of full analogy between human immune system and information security system; moreover, multiple mechanism of protection implemented in human immune system are absent in the information security system, or the other way around.
Identifying Organisational Climate Elements that can be used to Detect and Prevent Management Fraud
Authors: Bezuidenhoud Leon , Geldenhuys Dirk
Published: December 2020

Management fraud is a global problem that has become more widespread than ever before. Current modes for detecting and preventing fraud, such as those based on demographic factors, have not been very successful. It is argued that organisational psychology—more specifically the study of organisational climate—provides excellent vantage points from which to understand management fraud. The purpose of this study was to identify organisational climate elements that increase the potential risk of management fraud within an organisation. The study has done this in order to employ these elements in detecting and preventing potential management fraud. A mixed research design was employed, encompassing two broad phases, namely: classification, whereby a framework was developed; and empirical validation, which made use of analytical induction as well as Lawshe’s content validity ratio. It was found that leadership style and managerial values are the elements that relate most to the detection and prevention of management fraud. It was also found that ethical leniency, poor example setting and hypocrisy were likely to create climates in which management fraud takes place. In terms of values, the study found that it is not simply the adoption or communication of values that is important in shaping a fraud-conducive climate, but rather whether or not any professed values are seen to be implemented or lived.
Direct vs. Indirect Impact of Fuel Price on Wages in South Africa
Authors: Leshoro Temitope Lydia , Maluleke Glenda
Published: December 2020

The international oil price has been increasing significantly, but consumers react more to the announcement of the increase in fuel (pump) price, than an increase in international oil prices. This study, therefore, investigates the direct effect of fuel prices on the inflation rate and wages in South Africa, on the one hand, and the domestic price pass-through from fuel prices to wages (indirect effect) on the other. The impulse-response function of the vector autoregressive (VAR) technique was used to examine the direct and indirect effects of fuel prices on the inflation rate and wages, as well as the domestic prices pass-through from fuel prices to wages in South Africa. Quarterly data from 2001Q1 to 2018Q2 were utilised. The empirical results showed that inflation and wages responded positively to the shock in the fuel price. The results indicated that although wages increased because of a shock in the inflation rate—depicting the pass-through from the fuel price—the direct impact of the fuel price on wages is more significant. This study departs from the usual studies that examine the exchange rate pass-through of international oil prices to the inflation rate. The conclusion drawn was that the pass-through effect was not as strong and did not contribute as much as the direct effect of the fuel price. Therefore, the indirect shock of fuel prices, via inflation, does not so much cause an increase in wages as its direct shock. The study concludes with policy recommendations.

Molecular Modelling Reveals Eight Novel Druggable Binding Sites in SARS-CoV-2’s Spike Protein
Authors: Ugur Marion Ilke , Marion Antoine
Published: December 2020

Spike glycoprotein (S), one of the signature proteins of the SARS-CoV-2, initiates the membrane fusion and virus entry to the host cell. The S protein’s key role in virus viability makes it an attractive candidate for drug design studies. Besides the recent structural characterization of the S protein, information fundamental to drug design such as possible binding sites or molecular fragments with high affinity towards the protein is unknown. We explored the druggability of this protein, focusing on its S1 and S2 domains. We performed virtual screening studies on both closed and open forms of the protein, using both cryo-EM structures and geometries obtained from molecular dynamic simulations. We targeted 20 distinct ligand binding centres with a set of about 9,000 molecules. Our docking calculations followed by molecular mechanics-based refinement of ligand/protein complexes led us to detect eight binding sites that were so far undocumented. By further focusing on a subset of approximately 1,000 approved and marketed drugs, we aimed at suggesting a new direction for drug repurposing strategies that were not considered so far. Within this approved set, our best hits include a number of antibacterial and antiviral drugs (e.g., Streptomycin, Nelfinavir), which were not yet investigated clinically in treating COVID-19. We also identified some molecules (e.g., folic acid, Famotidine) that were already suggested to be effective towards SARS-CoV-2, yet without molecular explanation. Our results also indicate a great affinity of SARS-CoV-2’s S protein towards nucleoside analogues, either approved or experimental.

Authors: Kato Minami , Masese Titus , Yoshii Kazuki
Published: December 2020

Potassium-ion batteries have been envisioned to herald the age of low-cost and high-performance energy storage systems. However, the sparsity of viable components has dampened the progress of these energy devices. Thus, herein, we report coronene, a high-voltage cathode material that manifests a high-voltage of 4.1 V enkindled by anion (de)insertion. This work not only illuminates the broad class of polycyclic aromatic hydrocarbons as prospective cathode materials but also sets a new benchmark for the performance of future organic cathode materials.
Development of Lock-in Based Overtone Modulated MARY Spectroscopy for Detection of Weak Magnetic Field Effects
Authors: Konowalczyk Marcin , Foster Vander Elst Olivia , Storey Jonathan
Published: December 2020

Modulated magnetically altered reaction yield (ModMARY) spectroscopy is a derivative variant of fluorescence detected magnetic field effect measurement, where the applied magnetic field has both a constant and a modulated component. As in many derivative spectroscopy techniques, the signal to noise ratio scales with the magnitude of the modulation. High modulation amplitudes, however, distort the signal and can obscure small features of the measured spectrum. In order to detect weak magnetic field effects (including the low field effect) a balance of the two has to be found. In this work we look in depth at the origin of the distortion of the MARY signal by field modulation. We then present an overtone detection scheme, as well as a data analysis method which allows for correct fitting of both harmonic and overtone signals of the modulation broadened MARY data. This allows us to robustly reconstruct the underlying MARY curve at different modulation depths. To illustrate the usefulness of the technique, we show measurements and analysis of a well known magnetosensitive system of pyrene / 1,3-dicyanobenzene (Py/DCB). The measurements of first (h1) and second (h2) harmonic spectra are performed at different modulation depths for both natural isotopic abundance, and perdeuterated pyrene samples.

Published: December 2020

Supramolecular self-assembly of small organic molecules has emerged as a powerful tool to construct well-defined micro- and nanoarchitecture through fine-tuning a range of intermolecular interactions. The size, shape, and optical properties of these nanostructures largely depend on the temperature and polarity of the medium, along with the specific self-assembled pattern of molecular building units. The engineering of supramolecular self-assembled nanostructures with morphology-dependent tunable emission is in high demand due to the promising scope in nanodevices and molecular machines. However, challenges are probing the evolution of molecular aggregates from a true solution and directing the self-assembly process in a pre-defined fashion. The structure of molecular aggregates in the solution can be predicted from fluorescence correlation spectroscopy (FCS) and dynamic light scattering (DLS) analysis. On the other hand, the morphology of the aggregates can also be visualized through electron microscopy. Nevertheless, a direct correlation between emission from molecular aggregates in the aqueous dispersion and their morphology obtained through a solid-state characterization is missing. In the present study, we decipher the sequential evolution of molecular nanofibers from solution to spherical and oblong-shaped nanoparticles through the variation of solvent polarity, adjusting the hydrophobic-hydrophilic interactions. The intriguing case of molecular self-assembly is elucidated employing a newly designed π-conjugated thiophene derivative (TPAn) through a combination of steady-state absorption, emission measurements, FCS, and electron microscopy. The FCS analysis and microscopy results infer that small-sized nanofibers in the dispersion are further agglomerated, resulting in a network of nanofibers upon solvent evaporation. The evolution of organic nanofibers and subtle control over the self-assembly process demonstrated in the current investigation provides a general paradigm to correlate the size, shape, and emission properties of diverse fluorescent molecular aggregates in complex heterogeneous media, including a human cell.

Published: December 2020

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a pandemic which not only created a situation of dealing with public health emergency but also triggered the financial crisis of international concern. The current situation demands rapid, convenient and reliable diagnosis of the disease to downregulate its spread. Primary method of diagnosis presently being used, such as nucleic acid testing (RT-PCR), CT scans etc. involve time-consuming advanced machinery for imaging/ RNA replication and highly skilled technicians which could be only done in a laboratory set-up. A rapid, simple yet selective naked eye detection methodology that does not require any advanced instrumental techniques is highly desirable. In this study, we report computational results which could form the basis of a simple and rapid strategy for the detection of SARS-Cov-2 using peptide (screened from angiotensin-converting enzyme 2 (ACE2) receptor of host cell) functionalized gold nanoparticles (GNPs). This is based on the preferential binding of viral spike (S) protein to ACE2 receptor situated on the surface of the host cell membrane by which the virus gains access to the host cell. The interaction of peptide coated GNPs with spike protein has been investigated using coarse grained molecular dynamic simulations. The potential of mean force calculation of spike protein confirmed strong binding between peptide and receptor binding domain (RBD) of spike protein. The results presented here demonstrate the potential of this peptide coated GNPs-based system in the development of convenient sensors for the clinical diagnosis.

Published: December 2020

Polydimethylsiloxane (PDMS) is the most widely used silicon-based polymer due to its versatility and the range of attractive properties. Fabrication of PDMS involves liquid phase cross-linking to obtain hydrophobic and mechanically flexible material in the final solid form. This gives opportunity to add various fillers to affect the properties of resulting material. In the present work, we describe simple and reliable method of making a PDMS-based composite material with significantly improved thermal insulation properties by adding hollow glass microspheres (HGMs) to the mixture of liquid base and cross-linker (10:1 ratio) followed by degassing and heat-assisted crosslinking. We obtained 31% reduction of thermal conductivity for samples with HGMs content of 20% by mass. At the same time, sound insulation capacity slightly decreased as a result of lower density of PDMS-HGMs composite in comparison to pure PDMS. The wettability of the samples had no dependence on HGMs content.

Globally, the amount of loss due to smoking has been well documented. But smoking among teenagers not only dwells on the problem of physical danger in the form of illness or death but also damages emotions and behavior. The phenomenon of smoking among adolescents takes attention because the future of a nation is determined by the quality of its future generations. This paper focuses on understanding cigarette promotion strategies and juxtaposing them with anti-smoking health promotion strategies with the literature review method. The results show that there are gaps in themes and content where health promotion strategies are considered rigid and have not yet adapted to the development of millennial adolescents. The recommendations given should be that themes and content in health promotion be packaged more interactively and flexibly according to the current era. Incorporating elements of anti-smoking health promotion into the game features will allow health promotion to be more acceptable among teenagers.

Literature Review: Efektivitas, Keamanan, dan Biaya Terapi Imidafenacin untuk Pasien Overactive Bladder
Authors: Halim Steven Victoria
Published: December 2020

Imidafenacin is a new antimuscarinic agent in Indonesia that was recently approved in 2019 to treat overactive bladder (OAB) symptoms, including urinary incontinence, urinary frequency, and urinary urgency. As a new OAB medication in the Indonesian commercial market, a comprehensive review on the efficacy, safety, and cost of imidafenacin are essentially needed to optimize the responsible use of this drug, particularly in the era of universal coverage implementation in Indonesia. This review aimed to describe the profile of imidafenacin and to compare the efficacy, safety, and cost of imidafenacin with the other antimuscarinic drugs in Indonesia, and the guideline recommendations towards when to use imidafenacin for OAB treatment. Only results from systematic reviews and meta-analyses were used in the efficacy and safety comparison. Our review found that the efficacy of imidafenacin was relatively comparable to the other antimuscarinic drugs in Indonesia, including solifenacin, tolterodine, dan propiverine. Also, a better safety profile was found in the imidafenacin group, in particular, imidafenacin caused less dry mouth and constipation. This could be attributable to the higher affinity of imidafenacin to the M3 receptor resulting in less antimuscarinic effect at the other receptors. From the cost perspective, the cost of medication by using imidafenacin was relatively lower compared to the other antimuscarinic drugs in Indonesia. It, therefore, could be suggested to use imidafenacin as a potential agent for OAB.

A aventura semiológica de Barthes
Authors: Araujo Rodrigo da Costa
Published: December 2020

Compreendendo por semiologia a ciência que se dedica ao estudo da significação na vida social, este ensaio breve desenvolve, em um primeiro momento, uma possível função social e trajetória de tal ciência, de acordo com o viés barthesiano. Em seguida, considera a hipótese, segundo a qual a conjunção dessa função com o estudo sistemático da significação desdobra-se para a configuração de um impasse da semiologia, o qual é tanto previsto quanto lido, criticamente, por Roland Barthes (1915-1980).

Diversos fatores interferem no processo de ensino-aprendizagem, entre eles a forma de abordagem dos conceitos nos livros didáticos adotados pelos professores em sala de aula. Sendo assim, objetivou-se com este artigo observar a abordagem dos conceitos em três livros didáticos de Cálculo com relação ao conteúdo “Limites de Função de Uma Variável Real”. Essa observação foi feita à luz dos estudos de Duval (2003), principalmente em relação aos registros de representação semiótica. Percebeu-se, pelas análises, que duas obras apresentam os vários registros de representação na exposição teórica, mas supervalorizam as manipulações algébricas nos exercícios, não explorando satisfatoriamente outras formas de representação. Já em outra obra, verificou-se a utilização de uma abordagem que estimula a transição entre as várias linguagens matemáticas, tanto na exposição teórica como nas atividades práticas, o que pode contribuir para que o estudante compreenda, efetue e controle a diversidade de processos matemáticos propostos numa situação de ensino.

The origin of dolomite –a common carbonate mineral– is the subject of an ongoing debate. It has been proposed that extracellular polymeric substances (EPS) excreted by microbes contain specific organic molecules that facilitate the incorporation of magnesium in the carbonate minerals. We characterized the EPS produced under different conditions by measuring total carbohydrate (TCHO), total protein (TP) content and by (FTIR) analysis. We report the formation of Mgcarbonates with a mol% Mg higher than 41%, exclusively in association with EPS, rich in carbohydrates (TCHO > than 75% of the total EPS mass). Moreover, FTIR analysis of these EPS revealed the presence of protein secondary structures (e.g., β-sheets) known to favor mineral nucleation. These results suggest that some organic molecules with specific functional groups (e.g., carboxyl and hydroxyl groups) may be of key importance for overcoming the kinetic barriers that else prevent the incorporation of Mg into carbonate minerals, a crucial step for the formation of dolomite in natural environments.

Phycocyanin is one of the major light harvesting accessory pigment present in microalgae and cyanobacteria. This water-soluble pigment protein exhibits antioxidant, anti-inflammatory, and neuroprotective effects. Application of this pigment has also been used in dietary nutritional supplements in many food, nutraceutical, cosmetic, and biotechnology industries. In the present study phycocyanin was extracted from locally isolated marine cyanobacteria Geitlerinema sp. Geitlerinema sp. showed a higher growth during the summer perioed of 0.75 g/L and 0.54 g/L. Similarly, the maximum Phycocyanin obtained was up to 7.1% during summer period.

The constant utilization of hydrocarbon-based fuels such as petroleum, coal, and natural gas has resulted in the detection of high concentration levels of sulfur containing gases in the atmosphere of many countries, including Qatar. Among those potential air pollutants, the rising concentrations of H2S and SO2 are of serious concern. In this work, sulfur-based seed solutions (SBSSs) such as sulfite or sulfide solutions are made by purging sulfur-containing gases released from industry into alkaline solutions. These SBSS solutions are simultaneously utilized towards the production of renewable hydrogen energy via a photoelectrochemical (PEC) process, and are used as draw solutions (DS) to produce diluted fertilizer water by a forward osmosis (FO) desalination process for agricultural irrigation purposes. The continuous bench scale of the integrated PEC-FDFO system was successfully demonstrated for simultaneous hydrogen production and dilution of SBSS DS. The experimental results showed that the reduction potential of SBSS DS in the PEC cell changes with variation of SBSS DS concentration and pH. This resulted in the continuous oxidation of sulfite into sulfate and led to more hydrogen production. Moreover, FDFO process exhibited high percentage of water recovery and DS dilution up to 80% and 68% at high SBSS DS concentration, respectively. In binary mixture of SBSS DS, increasing the concentration of ammonium sulfate (NH4)2SO4 led to high water flux to about 42%. The outcomes of this experimental study showed a successful practical continuous integrated system toward hydrogen production and fertigation.

This work is focused on the design and fabrication of hydrogel sensors for the agricultural applications, “a multi-sensory device”. Agriculture is an important contributor to Qatar’s economy, as the country is aiming to produce more local products. We chose to use hydrogel in soil, for their high efficiency in absorbing water. The hydrogel will be embedded in a multisensory device that will provide consistent plant watering when soil is dry and in need for water. The multi-sensory device will employ NFC switch “Near Field Communication” which is a wireless communication device used to control water flow for plant irrigation. Also, the experimental work including enhancing soil properties by using Arabic gum (sodium 2-[(7-carboxyheptyl)-Chydroxycarbonimidoyl] benzen-1-olate), a biodegradable and naturally available polymer. It is proven that it decreases soil porosity, enhances the reinforcement between the soil and the hydrogel therefore retaining more water and preventing evaporation, it also increases plant growth through fixating nitrogen in the soil.
Algae-based Biofertilizer for Date Palm Cultivation in Qatar

Published: December 2020

Date palm (Phoenix dactylifera L.) is the main fruit crop found in the arid and semi-arid regions of the world. It naturally adapts to the adverse environments of extreme heat and water scarcity and prevents further desertification in addition to producing fruits with high nutritional value. It is seen in many parts of the world that traditional cultivation practices such as mixed planting and chemical fertilizers have led to low fruit quality resulting in low market values. Long generation time also hinders production of the dates. Tissue culture is therefore considered the most promising solution for rapid large-scale production of trueto- type clonal plants. The plantlets originating from in vitro callus proliferation are transferred from synthetic media to soil. The conventional method of using chemical fertilizers also leads to low plantlet viability with increased environmental and health risk. The current research targets the use of a local microalga, Tetraselmis sp. QUCCCM8, identified as an organic source of nutrients, a substitute for chemical fertilizers to acclimatize cultured date palmlets to soil. Soil was supplemented with different concentrations of algal biomass and plant growth was monitored for 3 months. Soil without any fertilizer and soil amended with 1 g conventional fertilizer were used as negative and positive control, respectively. Supplementation with 0.5 g of algal biomass led to higher plant growth rates, 100% survival rates, high ability of rooting (3.17 ± 0.14 roots), higher number of leaves (2.5 ± 0.25 leaves), largest stem thickness, longer shoot (33.75 ± 1.56 cm), and higher total chlorophyll (159.61 ± 9.6 mg L⁻ ¹) as compared to conventional fertilizer. These stated findings are significantly higher than the control. Furthermore, elemental analysis of the soil showed that supplementation with algal biomass increased the soil total nitrogen, potassium, and phosphorus contents essential for plant growth. Finally, the comparison of heavy metals composition between soils amended with conventional fertilizer and algae-based fertilizer highlights the potential use of algae as a safe and efficient biofertilizer post tissue culture mode of plantlet generation. This enhanced the viability of healthy plantlets without affecting the environment, averting usage of chemical fertilizers.

Published: December 2020

Microalgae are believed to be a promising source of different high value products (HVP). HVP are metabolites which are produced during the growth of microalgae and their production is triggered by the physiochemical growth conditions of the microalgae. The present project is aimed at exploring the presence of bioactive compounds in desert microalgae Desmodesmus sp. and to assess its ability to support and improve health care in Qatar. The isolate was cultivated under conventional conditions as a control, and under 3 different stress conditions to enhance the production of high value products. Then crude algal extracts were used to assess the biological activity. Results of the study suggest that Desmodesmus sp. produces high value products that exhibit great anti-oxidant, anti-proliferative and anti-bacterial activity when cultivated under conventional conditions and under continuous light stress.
