Abstract
Neurologic disorders are common reasons for emergency consultations. The majority of neurologic disease manifestations in the emergency room (ER) are life-threatening and require urgent treatment. The goal of this study is to investigate the epidemiology and clinical characteristics of different neurological disorders among emergency department admissions in Mogadishu.This is a cross sectional study conducted in the emergency department of Mogadishu Somali Turkish Training and Research Hospital from July 2021 to February 2022. The clinical and epidemiological characteristics of adult patients with neurologic manifestations in the emergency room were evaluated. Age, gender, distribution of neurological disease manifestations, neurological examination findings, and neurological diagnoses made by consultant neurologists were assessed. During the study period, 321 patients out of 8,500 were included in the study accounting for 3.7 percent of all emergency admissions. The majority of the patients in the study were 50 years of age or older (59%). The male subjects accounted for 56% of the total, while females accounted for 44%. Hypertension was the most common co-morbidity among subjects (38%), followed by diabetes mellitus and heart disease. The admission rate was high (78.2%) after neurological evaluation. The most common reason for a neurology consultation (43.9%) was altered mental status, followed by motor deficits and seizures. Ischemic and hemorrhagic strokes were the most common diagnoses after neurological evaluation (38.9% and 20.2%, respectively). Among subjects evaluated due to altered mental status, stroke was the most common diagnosis, followed by encephalopathy and status epilepticus. Patients with neurological manifestations in the ER require a multidisciplinary approach. This study illustrates the pattern of neurological emergencies in Somalia’s largest referral hospital and also highlights the significance of neurological assessment by a neurologist in the ER. In our study, hemorrhagic and ischemic strokes were the most prevalent neurologic presentations in the ER, particularly among the elderly.
Active Multi-Target Search Using Distributed Thompson Sampling
Authors: Chen Jun , Dames Philip 
Published: July 2022

Abstract
Distributed search and track is a canonical task for multi-robot systems, encompassing applications from environmental monitoring to disaster response to surveillance. In many situations, the distribution of objects in a search area is irregular, with some areas having high object densities while other areas have low densities. In this paper, we formulate the search task as a multi-armed bandit problem and propose a novel distributed formulation of Bernoulli Thompson sampling that enables robots to share coarse global information across the team. We demonstrate that this new formulation significantly accelerates the speed at which robots find targets compared to previous distributed search approaches. This effect is even more pronounced when the distribution of targets is clustered within small subregions of the search space.

Published: July 2022

Abstract
The Central Region of Ghana is endowed with rich kaolin deposits with immense potential industrial application which largely remain untapped due to limited information on geochemical properties. This paper assessed the geological composition of kaolin deposits with the view of elucidating their use in the formulation of climate-smart Portland cement. Four kaolin deposits in the Central Region were randomly selected and 20g each of 90mm of the kaolin samples from the selected deposits were analysed using X-ray diffraction (XRD) for the mineralogical composition and X-ray fluorescence (XRF) for the elemental composition. The results from the XRF determination were used in the principal component analysis. It was also used to compute geochemical indices, such as chemical index of alteration (CIA), chemical index of weathering (CIW) and the index of compositional variability (ICV) to determine the intensity of weathering of the kaolin as well as identify the different rock types from which they originated. The chemical index of alteration (CIA) values ranges from 86.7% (kaolin deposits in Ekon) to 95.8% (kaolin deposits in Saltpond), which suggest an extreme silicate weathering of feldspars; the chemical index of weathering (CIW) values obtained also ranged from 96.6% to 98.6%, which indicate an increasing degree of weathering; index of compositional variability (ICV) varies from 0.19 to 0.66 as well as low K2O/Al2O3 ratios indicate that kaolin deposits in the study area is compositionally mature and are rich in kaolinite. The geochemical characteristics of studied kaolin suggest that, they can be used in the ceramic, cosmetic, pharmaceutical, paper and other industries. Also, the high concentration of titanium dioxide found as anatasse reduce the quality of the kaolin which needs to be removed. The removed titanium dioxide can then be used in the formulation of climate-smart cement.

Abstract
This study represents a new line of research focused on the potential effects of a hybrid learning model on established health predictors (sleep and activity level) during the COVID-19 pandemic. This research explored the correlation between the mode of education delivery (online vs. in-person classes) to the students’ sleep duration and activity level. Current literature supports the paradigm that lower physical activity leads to negative health outcomes. At the time of this writing, there was a lack of scientific knowledge on the pandemic-produced ratio of online courses taken per day and face-to-face classes taken per day and how those differences may affect sleep duration and activity levels of college students. The results of this study showed an inversely correlated relationship between the utilization of a HyFlex (online and in-person delivery mode) learning model and students’ activity level. For each additional online class a student took in a given day (when compared to the same student going to in-person classes) the amount of mild activity decreased by nearly 7 minutes (b = − .115, p < .001). This research also found that taking online classes had the same effect on vigorous activity levels, decreasing the time spent in activity by 2.1 minutes for each online course taken on any given day (b = − .035, p = .020). This relationship between online learning and activity level is important in understanding the potential negative effects on physical health for college students as educators try to deliver a robust learning experience via online education both during and after the COVID-19 pandemic.

Abstract
Owing to huge benefits derived from understanding the complexity and association of the food, energy and water, delineation of prospective food-energy-water nexus has been carried out over the Ghana to provide insight into the existing relationship and correlation between the food-energy and water. To achieve this goal, researchers used the fuzzy analytical hierarchy process (FAHP) multi-criteria decision making (MCDM) technique and geographic information systems (GIS) to create a foodenergy-water nexus potential map (FEWM) by combining nine (9) evidential layers that contribute to food, energy and water systems. Three decision makers (DMs) utilized their expertise in modeling food energy water interconnectedness to assigned weight to these 9 strata using the FAHP approach, focusing on their relative importance in terms of food-energy-water nexus characterization within Ghana. Using a fuzzy gamma operator value of 0.9 in GIS, the weights acquired for the various evidential layers were normalized and then merged to produce the FEWM which graphically depicts the food-energy-water nexus over the country.

Перенести в английский вариант Purpose. To assess the effect of adequate laser coagulation (LC) of peripheral vitreochorioretinal dystrophy (PVCRD) on the clinical and functional state of the retina and the microcirculation of the macular region. Material and methods. Ganzfeld electroretinogram (ERG), multifocal ERG (mfERG), and optical coherent tomography with a function of angiography (OCTA) were performed for the retina of 22 patients (37 eyes), aged 20 to 62, who had been given an adequate volume of LC to treat dangerous types of PVCRD. The tests took place before LC and 1, 3, 6, 9, 12 months after it. To analyze the results, two groups were formed: (1) 27 eyes with LC volume of less than 200 coagulates and (2) 10 eyes with LC volume of more than 200 coagulates. Results. After LC, we observed a moderate decrease in the amplitudes of scotopic ERGs and the a-wavepeak latency lengthening in the maximal ERG. In the 2 ndsubgroup, the amplitude of the second wave of oscillatory potentials (OP2) and the OP index decreased more significantly than in the 1st, subgroup (by 17 and 21 % from the initial values, respectively, p<0.05). The cone and flicker ERGs in the 1st subgroup did not change, while in the 2nd subgroup the amplitude showed a stable decrease by 10 to 20 % as compared to the data before LC. As shown by mfERG, in the 2nd subgroup the functional activity of the macular region was moderately and reversibly declining. OCTA showed a general decrease in blood flow density (by 6.6% against the initial data) after LC, which reached the minimum 6 months after the intervention, with subsequent recovery in another 6 months. The recovery of blood flow density was complete in the 1st subgroup and partial in the 2 nd subgroup. Conclusion. LC of PVCRD in an adequate volume leads to a moderate general decrease in retinal activity with the restoration to the initial amplitudes of scotopic and photopic ERGs, and mfERG within 6 to 12 months. OCTA also showed that LC conducted in an adequate volume does not significantly impair the microcirculation in the fovea zone. A moderate depression of blood flow was more pronounced in the subgroup with the higher number of coagulates.

To evaluate macular thickness in patients with pseudoexfoliation syndrome (PXS) after phacoemulsification. Materials and methods. 30 patients with PXS (mean age 74.05 ± 5.21 years) and 31 age-matched patients (mean age 71.35 ± 7.51 years) without PXS (control group) were examined to assess macular thickness, which was measured by optical coherence tomography before phacoemulsification, 2 weeks, 2 and 6 months after it. Results. A significant increase in retinal thickness was noted in patients of both groups in parafovea 2 weeks after phacoemulsification, in parafovea and periphovea after 2 months, and in parafovea after 6 months. At 2 months after surgery, in patients with PXS, the thickness o f the retina in the fovea and perifovea was significantly higher than in the control group; at other times, no difference was observed between the groups. Conclusion. PXS does not affect macular thickness after phacoemulsification if no intraoperational or postoperational complications took place.

Published: July 2022

Abstract
This work reports a study of corrosion lifetime of transparent electrodes deposited on the microscopic glass substrate. A procedure was developed for obtaining the transparent electrode by spray method. The corrosion lifetime variation in the presence of 1.5 M NaOH medium chemically degraded at room temperature before and after gamma irradiation was determined by measuring the evolution of the structure, electrical and optical characteristics. The mean values of transmittance up to 25 month before and after irradiation were calculated 91% ±6% and 96±7%, respectively. The average value of resistivity after corrosion and age time after γ-irradiation was 0.016±9% Ω.cm and 0.017± 4% at 1.0 kHz. No significant changes observed for 27 hr corrosion and 25 month age time of the transparent electrodes in NaOH solution.

Abstract
Coconut husk is generated yearly as waste in large quantities but majorly under-utilized. Also, as a result of high embodied carbon, cement production is one of the largest contributors to construction sector carbon footprint. Since accumulation of unmanaged agro-waste like coconut husk has an increased environmental concern due to its pollution effect, recycling it into sustainable construction materials is a viable solution for future generation. In this study, experiments were performed to investigate the influence of coconut husk ash nanomaterial (CHAN) inclusion on electrical characteristics of plain cement paste (BCP) and mortar (CSM) samples at curing ages of 7 and 28 days. The results showed increase in electrical resistivity, thermal constant, and activation energy with curing duration for heating and cooling cycles of BCP and CSM. With inclusion of CHAN, the developed cement paste (CAP) and mortar (CASM) possessed lower values in all cases compared to their counterparts. Also, during heating at 28 days, both the CAP and CASM exhibited decrease in thermal constant. Though electrical resistance of all the samples varied inversely with temperature, CAP and CASM were found to possess greater potentials to make building structures intrinsically smart. Hence, in addition to solving disposal problems, utilization of coconut husks as described herein could enhance development of safe, inexpensive, and sustainable buildings that have large temperature sensing volume.
Methods of Multi-Criteria Analysis in Technology Selection and Technology Assessment: A Systematic Literature Review
Authors: Kozłowska Justyna 
Published: July 2022

Abstract
Technology assessment and selection problems have gained importance in recent decades as the used technology often determines the enterprises’ competitive advantage. Due to the extensive catalogue of criteria that should be considered and, on the other hand, the extensive catalogue of available technologies and solutions, the decision-making process of choosing a technology becomes a significant challenge for organisations and individuals. This study aims to identify the main research directions and trends in the scientific literature on applying multi-criteria analysis (MCA) in the context of technology assessment and/or technology selection. The author conducted a bibliometric analysis of publications indexed in the Web of Science and Scopus databases. The methodology of this study also included identifying the most productive authors, countries, organisations, and journals and analysing the occurrence and co-occurrence of terms. Final analyses included 380 publications retrieved from the Scopus database and 311 documents retrieved from the Web of Science repository. The analysis of the occurrence of terms and keywords allowed distinguishing two main research directions in using MCA methods in assessing and selecting industrial and health and medicine-related technologies. Some sub-areas have also been distinguished within these two areas: energy and renewable energy technologies, waste management, biomedical and medical technologies, and drug production technologies.

Fruit is the most popular food element of Indonesian people, almost everywhere in Indonesia sells a variety of fruits, one of which is apples sold in various stores, ranging from traditional markets and supermarkets. However, pear sold by traders are not completely sterile from various bacteria on the skin and flesh of pear, another factor buyers hesitate in buying fruit, namely shelf life or durability for how long the fruit. Therefore, research was conducted on fruit sterilizing technology, one of which was obtained was ozone water purifier technology for fruit sterilizing. From this research, we innovated to develop a user-friendly ozone sterilization tool named ozone box. Several tests of this tool are carried out to determine whether it works correctly or not, the first is an endurance test between fruits sterilized with ozone and fruits that are not sterilized with ozone. This resistance test was conducted over several days and showed results that the physical appearance of fruits sterilized using ozone was much fresher compared to fruits that were not sterilized using ozone or washed clean water.
