The continues increase in population and market globalization necessitated offering additional services and mass production strategy deployment. Consequently, a dramatic increase in research studies have been directed towards mitigating the shift schedule harmful physical, psychological, and social life effects on the workers. In addition, studies are currently conducted to determine the optimal shift schedule and shift rota, which is capable to incorporate human factors and applicable to the environment adopted in. In Kingdom of Bahrain there are no studies that investigate the effects of shift schedule on the operators, neither provide clear guidelines to select the appropriate shift schedule based on the environment adopted in. Accordingly, the aim of this paper is to present the development of an effective shift schedule selection mechanism that considers the physical, psychological, and social life factors for Al-Dur Power and Water Plant in Kingdom of Bahrain. The research methodology adopted was based on survey and case study. The results of this research study concluded that the shift schedule selection procedure developed was capable to involve all the stakeholders associated in the shift schedule selection process.

Published: January 2021

Environmental threats of coal usage in the electricity production combined with the consumption of renewable and non-renewable resources had led to worldwide energy challenges. The cost of coal mining and economical and environmentally sustainable usage of mined coal could be optimized by efficient management of coal supply chain. This paper provides a mathematical model for improving coal supply chain sustainability including the cost of exergy destruction (entropy). In the proposed method, exergy analysis is used to formulate the model considering not only economic costs but also destructed exergy cost, while genetic algorithm is applied to efficiently solve the proposed model. In order to validate the proposed methodology, some numerical examples of coal supply chains are presented and discussed to show the usability of the proposed exergetic coal supply chain model and claim its benefits over the existing models. According to the results, the proposed method provides 17.6% saving in the consumed exergy by accepting 2.7% more economic costs. The presented model can be used to improve the sustainability of coal supply chain for either designing new projects or upgrading existing processes.

Published: January 2021

The article discusses methods for accelerating the operation of convolutional neural networks for autonomous robotics learning. The analysis of the theoretical possibility of modifying the neural network learning mechanism is carried out. Classic semiotic analysis and the theory of neural networks is proposed to union. An assumption is made about the possibility of using the symmetry mechanism to accelerate the training of convolutional neural networks. A multilayer neural network to represent how space is an attempt has been made. The conclusion was based on the laws on the plane obtained earlier. The derivation of formulas turned out to be impossible due to the problems of modern mathematics. A new approach is proposed, which involves combining the gradient descent algorithm and the stochastic completion of convolutional filters by the principles of symmetries. The identified algorithms allow increasing the learning rate from 5% to 15%, depending on the problem that the neural network solves.

Published: January 2021

Breast cancer is the most common cancer in Polish women and the second leading cause of cancer deaths. Screening mammography is the only recognized method for early detection of malignant neoplasm and provides to reduction in cancer related deaths so far. The sensitivity of this examination is strongly influenced by the structure of the breast and is definitely lower for breasts of type 2 and 3 in accordance to American College of Radiology. That is why it is suggested that women younger than 35 years should be examined with ultrasound if necessary, and for women 35 years and older it is recommended to perform mammography, as the primary breast study. Ultrasound elastography is noninvasive imaging technique which can contribute to increase the sensitivity and specificity of recognition breast lesions. There are two main types of elastography: static and shear wave one. According to tissue stiffness, static elastography encodes lesions using a 5-point color scale – the Tsukuba University Score. Improvements in the interpretation of non-invasive examinations with using ultrasound elastography were discussed. It is considered that addition ultrasound elastography to ultrasound B-mode can play an important role in verification focal lesions in the breast.

Published: January 2021

‘Circular economy‘ in agriculture centres on the production of agricultural commodities using a minimal amount of external inputs, closing nutrient loops and reducing negative discharges to the environment (in the form of wastes and emissions). This can be achieved through the (re)design of maintenance, repair, reuse, remanufacturing, refurbishing, and recycling. Under the principles of CE, products and materials approaching their end-of-life stage can be regenerated or restored or replaced. Circular agriculture is aimed at closing the loop of materials and substances, and reducing both resource use and discharges into the environment. New measures like environmental taxes, insurance for liability resulting from environmental damage, cap and trade system and environmental labelling can be explored to promote transition of a current linear model to a circular one. The circular economy in Nepal is in infant stage and there is plenty of works to be done in this sector. The results of the paper will be instrumental for the transition of Nepalese agricultural sector to a more circular one.

Animal originated proteins have great importance in meeting the daily protein need in a healthy and balanced diet due to their high protein content, amino acid pattern and good digestibility. Also, when included in a diet, they play an important role in the protection of individuals‘ health and improving the life quality with their vitamin and mineral content. The aim of this study is to investigate the changes in meat and meat products consumption habits of people and whether they are concerned about reaching meat and meat products during the COVID-19 pandemic. For that purpose, a 24-question survey of 1000 people from several cities of Turkey was carried out. The majority of the participants stated that their consumption of red meat (77%), poultry meat (81%) and fish (66%) did not change due to the COVID-19 pandemic, while 10%, 8%, and 3% of the participants said their red meat, poultry meat and fish consumption increased, respectively. In addition, 13%, 11%, and 31% of the participants said there was a decrease in their red meat, poultry meat and fish consumption, respectively. The major reason for the decrease in red and white meat consumption was economic reasons, however, the reason for the decrease in consumption of fish was difficulties in reaching. During the COVID-19 pandemic, until the date that the survey was done, 12% of the participants had concerns about reaching meat and meat products. The main cause of their concern was being unemployed or losing their job after the COVID-19 pandemic.

This study was carried out to investigate the effect of equi-protein replacement of soybean meal with groundnut cake on immune status, haematology and serum biochemical parameters of broiler chickens. A total of One hundred and twenty (120) Cobb‘s day old chicks were randomly allocated to five (5) dietary treatments of three (3) replicates and eight (8) chicks per replicate in a completely randomized design. The Diet I was the control diet with 100% SBM as the major plant protein source while in other diets, SBM was replaced with 25, 50, 75 and 100% GNC in equi-protein basis and designated as Diets II, III, IV and V respectively. Feed and water were provided ad-libitum throughout the experimental period of 56 days. Newcastle disease (ND) vaccines were administered following a stipulated regime. At the end of the experiment two birds were randomly selected from each replicate and slaughtered. Blood and serum was collected for haematological analysis, serum bioassay and HA/HI tests to determine antibody titres against ND vaccines. All data collected were subjected to one-way analysis of variance using SPSS software package. Results showed that haematological parameters were significantly influenced by the dietary treatments in which birds fed 50% equi-protein replacement of SBM with GNC had better PCV, basophil, MCH and MCHC values compared to that of birds in the other dietary treatments. The antibody titres of experimental birds were not significantly different among treatment groups. The diet with 50% equi-protein replacement of SBM with GNC elicited the highest antibody titres of Log28 and Log210 after the 1st and 2nd ND vaccinations when compared to the other diets. The serum total protein, globulin, albumin, and glucose were significantly influenced by the dietary treatments. The present result indicate that 50% equi-protein replacement of SBM with GNC in diets is not detrimental to health status of broiler chickens.

Nowadays, to have a job is the best way to get a successful personal development. However, we find that people with disabilities have difficulties in accessing the labour market, even when they have successfully completed their university studies. This paper describes and analyzes the situation of people with disabilities who have graduated from the ULPGC between 2000 and 2010. The career trajectories of 96 graduates have been reviewed by matching the records from the ULPGC and those of The Canary Islands Observatory of Employment (OBECAN). Four indicators have been used: job placement, registered unemployment, temporary employment, and occupation. The results show that one in two people achieves a job according to their training in the third year after graduation, which suggests certain positive effects of university studies on job placement

Published: January 2021

The objectives of this research to determine the combination of the process of precipitation and adsorption in reducing the content of pollutant metals in the hazardous waste category B3 (hazardous toxic substances) produced at the Polinela Analysis Laboratory. The study was conducted in May to November 2019. The results obtained from 3 (three) times of sampling in May 2019 obtained a description of the characteristics of heavy metal content in wastewater in the form of Aluminum (Al) an average of 1.59 ppm, iron content ( Fe) an average of 9.73 ppm and Cadmium (Cd) an average of 0.022 ppm. From these results it can be seen that the wastewater containing Al and Fe has passed the threshold quality standard of waste water that is allowed to be discharged into water resource (PP No.82 of 2001), while the Cd content is still below the threshold. Furthermore, through the precipitation process with Ca (OH)2 0.8 M and adsorption using activated charcoal with contact time of 3 (three) hours the content of pollutants in wastewater can be reduced to 0.92 ppm for Al metals and 0.1 ppm for metals Fe, so that it is below the standard quality of waste water that is allowed to drain in water.

Keywords: adsorption, precipitation, quality standard

The Bina Sarana Bakti Foundation (YBSB) implements an organic farming system, which is an agricultural management system with a terrace design with permanent beds that can ecologically (environmentally) improve land quality, provide stable and sustainable yields and income into the future. To provide water for plants so that organic farming can take place throughout the season, both in the rainy season and in the dry season, water reservoirs are built using existing water sources. Utilization of water in the cultivation of organic lettuce at the Bina Sarana Bakti Foundation is carried out with 2-level irrigation hose treatment, namely the interval of providing irrigation water for 3 days and 4 days. Data analysis used t test at 5% real level. The results showed that the theoretical amount of water for lettuce at the Bina Sarana Bakti Foundation was 714 l/bed/season which was almost the same as the actual water use of lettuce with an interval of 3 days of irrigation water including additional liquid fertilizer from rabbit urine. + water in open land in shade is 720 l/bed/season, however, it is much lower than the interval of providing irrigation water for 4 days in open land without shade, namely 4,980 l/bed/season. The production of lettuce in shade with an interval of 3 days of 30.4 kg/bed/season was much greater than the production of lettuce without shade with an interval of 4 days of irrigation water, which was only 24.7 kg/bed/season. The productivity of irrigation water for shaded lettuce with the provision of irrigation water at an interval of 3 days of irrigation is 42.22 kg/m³, much higher and more effective than lettuce without shade with an interval of 4 days of irrigation which is only 4.96 kg/m³.

The bactericidal activity against S. aureus, E. coli and fungicidal activity against C. albicans of polyclonal immunoglobulins G was established. Objectives. To evaluate the bactericidal and fungicidal activity of polyclonal immunoglobulins G isolated from patients with purulent-inflammatory diseases and to analyze its relationship with the type of pathogen of the infectious process and clinical and laboratory manifestations of the disease. Material and methods. Using the developed method the ability of polyclonal immunoglobulins G isolated from 45 patients with purulent-inflammatory diseases and 16 donors was determined to have bactericidal activity against S. aureus, E. coli and fungicidal activity against C. albicans without the participation of complement and immune cells. The ratio of viable and dead bacteria was evaluated by laser scanning confocal microscopy using propidium iodide as a marker of dead bacteria.Results. It was shown that immunoglobulins G isolated from patients with purulent-inflammatory diseases and donors may have their own bactericidal activity against S. aureus, E. coli and C. albicans without participation of the complement system and immune cells, while in patients with purulent-inflammatory diseases this activity is significantly higher than in persons without purulent-inflammatory processes. The relationship between the activity of immunoglobulins against S. aureus, E. coli and C. albicans with clinical and laboratory manifestations of pyoinflammatory diseases was analyzed.Conclusion. The findings suggest the presence of mechanisms of immunoglobulins G bactericidal activity against S. aureus, E. coli and fungicidal activity against C. albicans, which is not associated with participation of the complement system and immune cells.

Authors:   Main Directorate of Health of the Grodno Regional Executive Committee, Grodno, Belarus, Gavrilik A. A.
Published: January 2021

Background. To date, there are no evidence-based ways to assess patients ' trust in medical professionals. The relevance of searching for such methods for studying the level of social trust of foreign consumers of medical services in Belarusian doctors is not in doubt due to the annual increase in the export of medical services. Objective: to develop a new method for assessing the confidence of foreign patients in Belarusian doctors. Material and methods. Based on the Russian and foreign experience in studying trust in the provision of non-medical services and using the principles of sociology of medicine, an approach to the mathematical assessment of the level of trust of foreign consumers of medical services in Belarusian doctors has been developed. Results. The method includes a sociological survey with subsequent calculation of the index of trust in Belarusian doctors, determined on the basis of generalized trust indices (three types), the values of which are calculated based on the values of two indicators: the indicator of generalized trust of foreign consumers in Belarusian doctors and the indicator of the measure of personal trust of foreign consumers in Belarusian doctors. Conclusions. The method of calculating confidence indices needs to be implemented and further tested, the survey of foreign patients is planned to be conducted after each case of receiving medical care in the Grodno region.

Published: January 2021

UiO-66 is one of the most chemically stable Metal-organic frameworks (MOFs) available. However, little is known about its stability in organic solvents. In this study, we synthesized a highly defective UiO-66 (HD-UiO-66) and explored how its textural properties change when exposed to weak and strong acids, both organic and inorganic in nature, and dissolved in different solvents, water, dichloromethane (DCM), and tetrahydrofuran (THF). Exposing defective UiO-66 to weak acids and bases, such as acetic acid and triethylamine, maintains its crystalline structure and porosity, irrespective of the solvent. Sulphuric acid decomposes HD-UiO-66 in organic solvents but not in water, trifluoroacetic acid decomposes the framework only in DCM. Tetramethylguanidine decomposes HD-UiO-66 in organic solvents but mantains some of the MOFs porosity and crystalline structure in water, whereas potassium carbonate damages the MOF to a greater extent in water than in organic solvents. Our results show that the acid/base properties of the solvent modulate the strength of acids and bases and its polarity determines the extent of their solvation, thus playing a crucial role in altering the MOF’s textural properties. This systematic investigation highlights the central role played by the solvent in tuning the stability of MOFs, which is relevant for liquid-phase applications in acidic and basic environments, such as catalysis and adsorption.
Experimental Determination of Activation Energies for Covalent Bond Formation via Ion/Ion Reactions and Competing Processes
Authors: See Kit Melanie Cheung , Shepherd Samantha O. , Prell James , Webb Ian
Published: January 2021

The combination of ion/ion chemistry with commercially available ion mobility/mass spectrometry systems has allowed rich structural information to be obtained for gaseous protein ions. Recently, the simple modification of such an instrument with an electrospray reagent source has allowed three-dimensional gas-phase interrogation of protein structures through covalent and non-covalent interactions coupled with collision cross section measurements. However, the energetics of these processes have not yet been studied quantitatively. In this work, previously developed Monte Carlo simulations of ion temperatures inside traveling wave ion guides are used to characterize the energetics of the transition state of activated ubiquitin cation/reagent anion long-lived complexes formed via ion/ion reactions. The ΔH‡ and ΔS‡ of major processes observed from collisional activation of long-lived gas phase ion/ion complexes, namely collision induced unfolding (CIU), covalent bond formation, or neutral loss of the anionic reagent via intramolecular proton transfer, were determined. Covalent bond formation via ion/ion complexes was found to be significantly lower energy compared to unfolding and bond cleavage. ΔG‡ of activation of all three processes lie between 55 and 75 kJ/mol, easily accessible with moderate collisional activation. Bond formation is favored over reagent loss at lower activation energies, whereas reagent loss becomes competitive at higher collision energies. Though ΔG‡ are between CIU of a precursor ion and covalent bond formation of its ion/ion product complex are comparable, our data suggest covalent bond formation does not require extensive isomerization, supporting evidence from previous structural studies that these ion/ion reactions measure compact gas phase structures.

We report the atomic-scale structure of alumina layers obtained by atomic layer deposition (ALD) of trimethylaluminium onto partially dehydroxylated silica. Such a detailed insight into the atomic structure of the species formed with increasing Al content was gained using a variety of one- and two-dimensional solid-state nuclear magnetic resonance (NMR) experiments involving 27Al, 1H and 29Si nuclei. 15N dynamic nuclear polarization surface-enhanced NMR spectroscopy (15N DNP SENS) and infrared spectroscopy using 15N-labelled pyridine as a probe molecule reveal that aluminium oxide layers on amorphous silica contain both strong Bronsted and strong Lewis acid sites, whereby the relative abundance and nature of these sites, and therefore the acidity of the surface, evolve with increasing thickness of the alumina film.

We previously demonstrated that Milstein’s seminal diethylamino-substituted PNN-pincer-ruthenium catalyst for ester hydrogenation is activated by dehydroalkylation of the pincer ligand, releasing ethane and eventually forming an NHEt-substituted derivative that we proposed is the active catalyst. In this paper, we present a computational and experimental mechanistic study supporting this hypothesis. Our DFT analysis shows that the minimum-energy pathways for hydrogen activation, ester hydrogenolysis, and aldehyde hydrogenation rely on the key involvement of the nascent N-H group. We have isolated and crystallographically characterized two catalytic intermediates, a ruthenium dihydride and a ruthenium hydridoalkoxide, the latter of which is the catalyst resting state. A detailed kinetic study shows that catalytic ester hydrogenation is first-order in ruthenium and hydrogen, shows saturation behavior in ester, and is inhibited by the product alcohol. A global fit of the kinetic data to a simplified model incorporating the hydridoalkoxide and dihydride intermediates and three kinetically relevant transition states showed excellent agreement with the results from DFT.

We present a protein database search engine for the automatic identi?cation of peptide and protein sequences using the recently introduced method of two-dimensional partial covariance mass spectrometry (2D-PC-MS). Since 2D-PC-MS measurement reveals correlations between fragments stemming from the same or consecutive decomposition processes, the ?first-of-its-kind 2D-PC-MS search engine is based entirely on the direct matching of the pairs of theoretical and the experimentally detected correlating fragments, rather than of individual fragment signals or their series. We demonstrate that the high structural speci?city a?orded by 2D-PC-MS fragment correlations enables our search engine to reliably identify the correct peptide sequence, even from a spectrum with a large proportion of contaminant signals. While for peptides the 2D-PC-MS correlation matching procedure is based on complementary and internal ion correlations, the identi?cation of intact proteins is entirely based on the ability of 2D-PC-MS to spatially separate and resolve the experimental correlations between complementary fragment ions.

The risk of maturation failure in arteriovenous fistula (AVF) remains high. Curcumin poses antioxidant effects may enhance AVF maturation. This study evaluates the antioxidant effect of Curcumin on AVF maturation among type 2 diabetic patients (T2DM) with end-stage renal disease (ESRD). This was a single-blinded, randomized controlled trial conducted in three tertiary hospitals in Jakarta, Indonesia. Patients underwent the first hemodialysis. A total of 67 patients divided into groups of Curcumin, acetylsalicylic acid, and placebo. After 4 weeks, TAC level among the curcumin group was significantly higher compared to acetylsalicylic acid, and placebo groups 794.2(457.4±1473.7) µM vs. 519.2(247.7 ± 1027.7) µM and 794.2(457.4± 1473.7) µM vs. 542.5(281.91± 1054.64) µM, respectively (p<0.05). Also, TAC after 8 weeks was significantly higher among curcumin group compared to acetylsalicylic acid, and placebo groups (820.5(380.7± 1643.7) µM vs. 509.7(341.0± 981.91) µM and 820.5(380.7± 1643.7) µM vs. 497.7(324.7± 979.2) µM, respectively (p<0.001). The TAC level patients with mature AVF were also higher. A 2000 mg/day of curcumin increases antioxidant capacity after 4 and 8 weeks following AVF surgery among ESRD with T2DM.
