Authors: Umuogbana Umuogbana Augusine Onyemaechi , Onuchukwu Onuchukwu Chika
Published: June 2022

A statistical analysis on the main parameters of Coronal Mass Ejections (CMEs) and solar activity for solar cycles 23 and 24 has been carried out and reported. The data used for the analysis was obtained from SOHO/LASCO CME Catalogue by the Coordinated Data Analysis Workshop (CDAW), and Omini Services, for CME and solar activity respectively. The parameters for the CME analysis are Linear speed (LS) and Final speed (FS). The solar activity tracers analyzed are sunspot number (SSN) and sunspot area (SSA). We characterized and compared the CME parameter for each cycle, and then compared their monthly time series plots with the solar activity cycle for possible similarities. Also, for each parameter, same analysis was also done on various sizes of CMEs (normal, narrow and wide) segregated from All CMEs. A comparison of CME time series with solar activity (especially SSAT and SSN which seem to reflect the true general activity cycle) shows that CME linear speed follow the solar activity cycle though lags it by 3 months for cycle 24. CME distributions shows that Linear speed and final speed for All CMEs decreases from one cycle to the other; it appears so too for segregated CME angular sizes of both parameters. These changes is perhaps due to effects of solar wind. These changes are, perhaps, due to effects of solar wind.

Published: June 2022

Preliminary screenings are essential to limit the community propagating nature of COVID-19. COVID-19 patients’ lung health status can be assessed by chest radiographic imaging, such as computed tomography scanning or X-ray images. Therefore, it is preferable to use machine learning approaches to help identify COVID-19 by using chest radiographs. This research presents an image-based diagnosis of COVID-19 disease using Deep Learning. The presented work uses chest CXNet-A Novel approach for COVID-19 detection and Classification X-ray images because the X-ray imaging facility is widely available in almost all healthcare facilities. It is less costly and has a more negligible radiation effect than Computed Tomography (CT) scan images. This study employed the implemented a custom Convolutional Neural Network (CNN) model and pre-trained deep neural architecture such as resnet50, DenseNet121, VGG16, and VGG19 to classify COVID-19 chest X-ray images. The proposed model has been evaluated on the real-life data, the accuracy of 98% has been achieved. We can recommend the proposed model to health care professionals as a trustworthy diagnostic decision-making system for COVID-19 detection.

Authors: Tegegne Demeke Fantaw
Published: June 2022

The water quality of Lake Ziway is deteriorating due to human intervention. The objective of this research was to analyze the water quality of the lake. Analysis was done for color, odor, pH, EC, TDS, turbidity, ammonia, total hardness, sodium, potassium, total iron, manganese, calcium, magnesium, alkalinity, bicarbonate, chloride, Sulphate, nitrate, nitrite, fluoride, phosphate, DO, BOD and COD at seven sites from February to March in 21 runs. This research utilized international and national drinking water quality guidelines and standards for the statistical evaluation of experimental results. The mean values of turbidity, manganese, BOD, and COD levels exceed the WHO standards. All water quality parameters have significance values of P ≤ 0.05 for spatial variation except BOD and COD that have P- values of 0.196 and 0.143, respectively. Whereas significant temporal variations were only observed for potassium (0.03), BOD (0.001), and COD (0.002). The cluster analysis showed two significant clusters for both water and sediment samples. This study indicated that the major causes of water quality deterioration are the inflow of effluents from the floriculture industry, domestics, agricultural practices, saline seeps, and other uncontrolled human interventions as observed in sites one, two, three, four, and five. The other cause results from people’s activities in boats and islands. Run-off, silt, waste effluents, etc. probably were the causes of the lakes' pollutions as shown in cluster one.

Authors: Ullah Khalil , Aslam Muhammad , Abbas Nasir , shah Syed Irfan
Published: June 2022

The method of paired comparisons (PC) endeavors to rank treatments presented in pairs to panelists (or respondents, judges, jurists, etc.) and they have to select the better one based on sensory evaluations. Sometimes the situations may occur when the panelists cannot discriminate between the treatments and declare a tie. In this study, an effort is made to extend the Weibull PC model to accommodate ties. The extended Weibull PC model is analyzed using Bayesian paradigm. Four different loss functions are used under noninformative (Uniform and Jeffreys) priors. The posterior and marginal posterior distributions are derived. The posterior estimates, posterior risks, preference probabilities, posterior probabilities and predictive probabilities are evaluated to know the ranking of ecological factor. The goodness of the proposed model is assessed. The entire analysis is carried out using a real data set based on the preference for the ecological factors.

Published: June 2022

Background
Pro-opiomelanocortin (POMC) neurons play a sexually dimorphic role in body weight and glucose balance. However, the mechanisms for the sex differences in POMC neuron functions are not fully understood.
Results
We detected small conductance calcium-activated potassium (SK) current in POMC neurons. Secondary analysis of published single-cell RNA-Seq data showed that POMC neurons abundantly express SK3, one SK channel subunit. To test whether SK3 in POMC neurons regulates POMC neuron functions on energy and glucose homeostasis, we used a Cre-loxP strategy to delete SK3 specifically from mature POMC neurons. POMC-specific deletion of SK3 did not affect body weight in either male or female mice. Interestingly, male mutant mice showed not only decreased food intake but also decreased physical activity, resulting in unchanged body weight. Further, POMC-specific SK3 deficiency impaired glucose balance specifically in female mice but not in male mice. Finally, although no sex differences were detected in the expression of SK3 and SK current in POMC neurons, SK current was significantly higher in male POMC neurons that co-express estrogen receptor α (ERα).
Conclusions
These results revealed a sexually dimorphic role of SK3 in POMC neurons in both energy and glucose homeostasis independent of body weight control, which was associated with the sex difference of SK current in a subpopulation of POMC/ERα neurons.

Authors: Heidari Mohammad Javad , Najafi Akbar , Borges Jose G
Published: June 2022

Due to the high cost of identifying and evaluating forest roads and the subsequent issue of maintenance, forest management has always faced challenges in terms of scheduling and implementation costs. Currently, monitoring the condition of forest roads has reached a critical stage due to budget allocation problems and lack of adequate supervision and requires low-cost or cost-effective monitoring. Today, smartphones have been used on public roads to identify road deterioration due to benefits such as usability, cost, ease of access, and expected accuracy. The use of smartphones in forest road development by the proposed system is a distributed information system that converts data from enterprise mode to field mode by harvesting and assessing forest road conditions and image processing technologies. The technology proposed in this research allows different information YOLOv4-v5 with improvements to this version including mosaic data augmentation and automatic learning of enclosing frames. In this research, we applied a new hybrid YOLOv4-v5 to the dataset's general applicability. We assessment forest road dataset to run an experiment, smartphone images by various aspects of the smartphone images (SI) dataset which is specialized for detect forest road deterioration. To enhance YOLO's ability to detect damaged scenes by proposed a new technique that takes information into frames. We expanded the scope of the model by applying it to a new orientation estimation task. The main disadvantage is the provision of qualitative model information on forest road activity and the indication of potential deterioration.
Ideal User Group: A New Perspective on Item Representation for Recommender Systems
Authors: Peng Zi-Feng , Zhang Heng-Ru , Min Fan
Published: June 2022

Item representation is a significant building block of recommender systems (RSs). Most existing methods are based on the inherent features of the item, such as its type, shape, and color. In this paper, we propose a new perspective to characterize items by building ideal user groups (IUGs). We define the IUG as the most suitable user group for an item, such as athletes are the IUG of fitness equipment. The construction of an IUG begins with separating user groups according to every single demographic attribute (gender, occupation, etc.), such as male or female groups by gender attribute. Subsequently, we calculate the average rating of each group based on historical records. The next step is to compare the average ratings of different attribute values for the same attribute (e.g., male and female in gender) of the demographics. Meanwhile , we employ Bayesian averaging to address the issue of certain user groups having fewer members but stronger preferences to achieve a fair comparison. Finally, we combine the attribute values corresponding to the group with the maximum average rating of each attribute to obtain the demographics of an IUG, such as female students in their 20s. To validate the effectiveness of the IUG, we propose an IUG-based neural Collaborative Filtering model. Experiments are taken on two real-world datasets in comparison with nine state-of-the-art methods. Results show that the application of the IUG is effective in terms of two metrics.

Published: June 2022

Background: Mother To Child Transmission (MTCT) of HIV is a threat in resource limited countries like Uganda where breastfeeding is the largest source of HIV transmission in children below the age of 5 years. The study was done to assess the compliance of HIV positive breast-feeding mothers to the Ministry of Health (MoH) recommended Infant and Young Child Feeding (IYCF) options to prevent MTCT of HIV in Mukono district.Methodology: This study enrolled a total of 380 HIV positive mothers of age 17 to 44 years with infants aged four years and below attending Naggalama hospital, Mukono COU hospital, Mukono Municipality health centre IV and Kojja health centre IV. Results: The results of the study revealed that 62.11% of the respondents complied with the recommended MoH IYCF options while the rest did not. 25.69% mothers had HIV positive children. Mothers who had babies aged between 13-24 months and mothers with secondary education were 2.55 and 2.29 times respectively more likely to comply with IYCF options. Mothers who practiced mixed feeding after 6 months; exclusive replacement feeding after 6 months and having HIV positive children were 0.002; 0.02 and 0.13 times respectively less likely to comply with IYCF options. Conclusions: Age of child and education of the HIV positive mother, the feed type practiced by the mother after six months and the HIV test result of children were all found to be predictors of mothers’ compliance with the recommended IYCF options.

Published: June 2022

Purpose
To explore radiological changes of the lacrimal gland (LG) in Graves’ ophthalmopathy (GO) and whether a combination of MRI parameters and clinical indicators can better predict individual clinical manifestation of GO compared to clinical activity scores (CAS) assessment.
Methods
A total of 28 patients with GO (56 eyes) were enrolled between July 2020 and July 2021. Patients were classified into either the active GO group ( CAS ≥ 3) and the inactive GO group ( CAS < 3). MRI data and clinical data of LG were collected. The diagnostic performance of MRI parameters and models was assessed by receiver operating characteristic curve analysis. Logistic regression predictive models for staging GO were compared.
Results
There were statistically significant differences in T2-mapping values (p < 0.001), the proportion of mild or no obvious redness of conjunctival (p < 0.001), and the proportion of swelling of caruncle or plica (p < 0.001) between inactive and active groups. In MRI based logistic regression model, the T2-mapping value was an independent risk factor (AUC = 0.832). When combining MRI and clinical indicators, T2-mapping value and age resulted as independent risk factors (AUC = 0.928). Swelling of eyelids, redness of conjunctiva, swelling of conjunctiva, swelling of caruncle or plica, and spontaneous retrobulbar pain can be replaced by other objective indicators (AUC = 0.937, 0.852, 0.876, 0.896, and 0.891, respectively).
Conclusion
The combination of the T2-mapping value of LG and clinical indicators can improve the stage prediction of Graves’ ophthalmopathy compared to CAS and provide a new idea for improving the objectification level of GO data collection.
Coronary stent-graft use to salvage a juxta-anastomotic arterial rupture complicating a case of radio-cephalic fistuloplasty
Authors: Lin Zhiyuan , Kallam Neha , Khurram Ruhaid , Midani Ammar Al , Khalifa Mohamed
Published: June 2022

Background:
Stenosis is a common complication of haemodialysis arteriovenous accesses. Endovascular approaches with percutaneous transluminal fistuloplasty have largely replaced open surgical approaches as first line treatment. Vessel rupture is an uncommon complication of fistuloplasty and most reports describe venous rupture. Stent-graft deployment can salvage this however its use requires careful assessment of the distal vasculature. Arterial rupture with fistuloplasty has rarely been described in the literature. This is a novel case describing the use of a BeGraft coronary stent-graft to manage juxta-anastomotic arterial rupture and pseudoaneurysm complicating fistuloplasty.
Case presentation:
A 77 year old female with end stage renal failure secondary to systemic amyloid light chain type amyloidosis was referred for a suspected radio-cephalic arteriovenous fistula stenosis after difficulty cannulating with poor flow during dialysis and clinical reduction in the fistula thrill. Both doppler ultrasound and intravenous fistulography confirmed a venous stenosis 2cm distal to the anastomosis. The stenosis was treated by fistuloplasty, however, this was complicated by a rupture of the juxta-anastomotic arterial segment intraoperatively. Intermittent balloon tamponade was used to minimise extravasation although a pseudoaneurysm formed within the damaged arterial segment. The patient’s distal neurovascular status was assessed using the Barbeau test and we sonographically confirmed adequate retrograde arterial flow via a complete palmar arch directing blood from the ulnar artery. After discussion with the renal transplant team, a 4mm BeGraft coronary stent-graft was deployed to control haemorrhage and bypass the pseudoaneurysm until adequate haemostasis and fistula flow was achieved. Follow-up 3 months post-procedure reported the patient continued with haemodialysis using the stented fistula with no further complications.
Conclusions:
To our knowledge, this is the first case report describing the application of BeGraft coronary stent-grafts to salvage fistuloplasty of a radio-cephalic arteriovenous fistula stenosis complicated by juxta-anastomotic arterial rupture and pseudoaneurysm formation. We demonstrate the safety and short-term efficacy of this technology.
Use of Chlorhexidine Gluconate Irrigation Solution to Prevent Postoperative Infection in Inflatable Penile Prosthesis: a Cost-effectiveness Analysis
Authors: McDermott Sean , Kaiser Melanie , Deibert Christopher
Published: June 2022

Inflatable penile prosthesis (IPP) placement for erectile dysfunction carries a risk of postoperative infection. This risk can be mitigated with intraoperative irrigation with antibiotic solutions. One such irrigant, chlorhexidine gluconate (CHG), has recently been introduced into the field of urology for IPP surgery. This investigation aimed to construct a Markov Model using established data from literature to define the incremental cost of complications following IPP and the range of infection rates at which CHG could serve as a cost-effective approach. The model produced found the incremental cost of infection/mechanical failure to be several thousand dollars when utilizing standard antibiotic regimens of Rifampin/Gentamicin ($2 483) and Vancomycin/Gentamicin ($3 066). However, if CHG irrigation is utilized instead, cost savings of several hundred to over a thousand dollars are observed, so long as CHG maintains below a 2.8% infection rate. The lower baseline cost and potential for equivalent or superior infection prevention with CHG make it an intriguing option for use in IPP surgeries.

Published: June 2022

This paper deals with a class of Leslie-Gower predator-prey model with Beddington-DeAngelis functional response function. We assume that predator reproduce much slower than prey, which yield a slow-fast system. Using the normal form theory and geometric singular perturbation theory, we provide a detailed mathematical analysis for the existence of supercritical Hopf bifurcation, canard explosion and relaxation oscillation. Numerical simulations are also carried out to substantiate our analytical results.2000 Mathematics Subject Classification: 34C37, 34C07, 37G15.
A free boundary problem with nonlocal diffusion and unbounded initial range
Authors: Li Lei , Li Xueping , Wang Mingxin
Published: June 2022

We consider a free boundary problem with nonlocal diffusion and unbounded initial range, which can be used to model the propagation phenomenon of an invasion species whose habitat is the interval $(-\infty,h(t))$ with $h(t)$ representing the spreading front. Since the spatial scale is unbounded, a different method from the existing works about nonlocal diffusion problem with free boundary is employed to obtain the well-posdeness. Then we prove that the species always spreads successfully, which is very different from the free boundary problem with bounded range. We also show that there is a finite spreading speed if and only if a threshold condition is satisfied by the kernel function. Moreover, the rate of accelerated spreading and accurate estimates on longtime behaviors of solution are derived.AMS Subject Classification (2000): 35K57, 35R09, 35R20, 35R35, 92D25
Macroeconomic Determinant of Domestic Savings in Nigeria: A Cointegration Approach
Authors: Ugah John
Published: June 2022

The crux of the study is to succinctly identify and examine the macroeconomic determinant of domestic savings in Nigeria. Historical time series data were collated from CBN, NBS, and IMF bulletins for the period 1990 to 2019. The data were tested and analyzed using the unit root test, Johansen co-integration test, and ECM regression technique. The outcome of the ADF unit root test shows that the variables were stationary while the empirical results for Johansen co-integration test conclude that there exists a long-run relationship between the variables. From the ECM regression result, deposit rate and inflation rate in Nigeria negatively and insignificant affect domestic savings in Nigeria. While income level was revealed to have a positive and significant impact on domestic savings in Nigeria. Albeit, financial deepening negatively affect domestic savings in Nigeria but the effect was statistically significant. Conclusively the study shows that the level of income, deposit rate, financial deepening, and inflation rate determines the volume of domestic savings in Nigeria – positively or negatively. It was recommended among others that the government and monetary authorities should set sound policies and a fertile environment to foster domestic savings that will help to increase the level of economic growth in Nigeria.

Performance Study of Steel Coupling beams in coupling shear-wall system
Authors: Rezapour Moin , Mirghaderi Seyedrasoul , Rajabnejad Hamid
Published: June 2022

Application of concrete coupling beams using diagonal reinforcement is a common practice which has certain limitations such as issues associated with their execution and their large depth to satisfy the stiffness, strength, and energy dissipation criteria. Steel coupling beams have a higher performance in terms of satisfying the stiffness and strength criteria with respect to the reinforced concrete beams with customary or diagonal reinforcement. 10 and 15-story buildings are designed in accordance with the energy absorption concept or plastic design based on the structure performance. The equivalent column method is used for modeling and the nonlinear behavior of the wall is modeled by two methods. In the first method, which is shown to have a better performance, the nonlinear behavior of the wall is obtained using ABAQUS software and is assigned to the wall base using the lumped plastic hinge method (Link element). The nonlinear behavior is defined in the second method using the semi-lumped plastic hinge (Fiber element). The capacity curves obtained from the pushover analysis show the limited ductility and displacement of concrete coupling beams because of rapid loss in the capacity curves compared with those modeled that used steel coupling beams. The incremental dynamic analysis using 20 earthquake records is performed on 2D models. In this research concluded that at the immediate occupancy performance level both the concrete and steel coupling beams have similar performances and approximately equal failure probabilities. But at the life safety and collapse threshold performance levels the structure with the steel coupling beam exhibits a better performance. Therefore, it seems that in the structures that are designed for IO performance level, there is no advantage between the two types of coupling beams. But at lower performance levels, the steel coupling beam would have a better performance.

Published: June 2022

Background: To develop a viable in vivo chorioallantoic membrane (CAM) model to study the growth and invasion of patient-derived Retinoblastoma (RB) and Choroidal Melanoma (CM) xenografts (PDXs). The study utilizes primary tumor samples instead of cancer cell lines which provides a more authentic representation of tumors due to conserved morphology and heterogeneity. Methods: Fertilized chicken eggs were procured, windowed, and their CAM layers were dropped. On embryonic development day (EDD) 10, freshly cut patient-derived CM and RB tumors were implanted on the CAM layer and the set-up was incubated for 7 days. The tumor-embedded CAM layer was harvested on EDD-17 and the extracted tumor samples were subjected to Hematoxylin and Eosin staining and Immunohistochemical analysis to evaluate the extent of tumor invasion. Results: Significant changes in the vascularity around the RB and CM PDXs were observed indicating an angiogenic environment. The cross-sectional histological view of the tumor implant site revealed the invasion of both the tumor types into CAM. Invasion of CM to CAM mesoderm was visualized in the form of pigmented nodules and of RB was indicated by synaptophysin and Ki-67 positivity in IHC.Conclusion: The CAM xenograft model was successfully able to support the growth of CM and RB PDXs and their invasion in CAM, thus presenting as a feasible alternative to mammalian models for studying tumorigenicity and invasiveness of ocular tumors. Moreover, this model can further be utilized to develop personalized medicine by inoculating patient-specific tumors for pre-clinical drug screening.

Authors: Elashmawi I. S. , Ismail A. M. , Abdelghany A. M. , Yassin A. Y.
Published: June 2022

This work aims to prepare LiZnVO4 nanoparticles and incorporate them into PVDF as a host polymeric material using the casting method for rechargeable Li-battery applications. The effect of LiZnVO4 on the structural and optical properties of the samples was studied using XRD, FT-IR, and UV-is techniques. Moreover, the electrical conductivity of the prepared films was studied. The XRD spectra show semicrystalline structure of PVDF and the rhombohedral structure of LiZnVO4. Scherer's equation was used to determine the crystallite size of LiZnVO4 which is nearly 83 nm. The interaction between PVDF and LiZnVO4 was approved by shifting some FT-IR bands. The band gap energies were decreased by increasing LiZnVO4 due to the density in the localized states in the mobility band gap in PVDF. The AC parameters as a function of frequency and temperature were investigated in detail. Both ε' and ε" had their maximum values at low frequencies and decreased as the frequency and temperature increased. The dielectric properties and tan δ were improved, particularly 5 wt% of LiZnVO4, which confirms the XRD and FT-IR results indicating their suitability as a suitable base material for designing and developing promising energy storage devices and lithium batteries.

Authors: Al-Jibory Mohammed Wahhab , Rahman Mokdad Hayawi
Published: June 2022

The development of methods for making fluids in a state of turbulence to obtain better heat transfer and its strong effect on the elastic wall. One of the ways that we can obtain the turbulent state of the fluid is to make one of the surfaces of the solid slide at a certain speed. This slip leads to the surface tension in a state of turbulence, and this rotates the fluid flow in a way large and in order to obtain better turbulence, it is used to make the surfaces surrounding the fluid in a directional way to help rotate the fluid. The results proved the effectiveness of this stereotype, as the force of the effect of the fluid velocity on the elastic wall was in the case of the thickness of 0.5 mm and the sliding velocity of 0.9 m/s, where the deformation was 5.6 mm, which is the best strike condition was deduced either at 2 mm thickness and 0.1 m/s sliding velocity where the deformation was 0.272 mm which is the least deformation reached by the wall.

Fatherhood and High-Risk Pregnancy: A Scoping Review
Authors: Jackson Kyle , Erasmus Erika , Mabanga Ntobizodwa
Published: June 2022

Background
The experience of expectant parenthood is commensurate of relative angst and nervousness albeit one of overall excitement and joy. However, when the pregnancy is regarded as high-risk, this experience changes dramatically for both parents. While literature on high-risk pregnancies is gaining traction, the focus is predominantly on the mother’s experiences and therefore, a paucity exists in exploring the father’s experiences of a high-risk pregnancy. This study aimed to determine the current extent of literature focusing on father’s experiences of a high-risk pregnancy using a scoping review methodology.
Method
Nine databases were reviewed using the EBSCOHost metadatabase: Academic Search Complete; APA PsychArticles; CINAHL Plus with full-text; Health Source: Nursing/Academic Edition; MasterFILE Premier; MasterFILE Reference eBook Collection; MEDLINE; SocINDEX with full-text; and eBook Collection. Data was extracted according to the following headings: Authors (including the year of publication); aim of the study; research context; research design; sample characteristics; and key findings.
Results
15 studies were included in this review. A narrative synthesis was applied within which 4 key themes emerged from the data: (1) The father versus the healthcare professional and the hospital environment; (2) The impact of high-risk pregnancies on fathers; (3) Redefining the role of ‘father’ after experiencing high-risk pregnancy and (4) Focus on fathers: Recommendations for support during high-risk pregnancies.
Conclusion
The findings of this study highlights the importance of the inclusion of men and fathers in supporting both his partner and (un)born child. The findings further illustrated the long-lasting impact of trauma felt by men which constrained his ability to support his family. A family-centred approach is needed to further support the family and the impact of a high-risk pregnancy on all members within the family unit.

Published: June 2022

The development of the housing and communal complex is focused on ensuring guaranteed access of the Russian population to high-quality drinking water. Due to the deterioration of drinking water quality, the mineral composition of sediments in the heating and hot water supply systems of the towns of Apatity and Kirovsk (the Murmansk region) has been studied. It has been established that sediments in the heating system mainly consist of iron oxides and oxyhydroxides: magnetite, goethite and lepidocrocite. All these mineral phases are products of active oxidation (corrosion) of steel pipes and heating system equipment. No mineral phases of ferrous forms of iron have been found in the sediment, which indicates sharply oxidizing environment in the heating system. The presence of sulfur-containing mineral phases, namely, anhydrous calcium sulfate - anhydrite and elemental sulfur, has been recorded in the heating system of the Apatity combined heat and power plant. Indirectly, the presence of such sulfur-containing phases may indicate the possible presence of microflora (bacteria) in the heat-transfer agent, in the metabolic processes of which sulfur and sulfur-containing compounds are involved.
Model evaluation of accuracy of obtaining total electron content by the method of spaced reception of low Earth orbit satellite signals
Authors: Cherniakov S. M.
Published: June 2022

A model-based technique to estimate the accuracy of the ionospheric total electron content (TEC) based on the data from spaced receivers of low Earth orbit satellite signals has been suggested. That allows us to estimate the total electron content errors for both quiet ionosphere conditions and under the presence of a plasma ring. To estimate the error, the dynamic model of the electron concentration of the Earth's ionosphere has been used. For the selected input parameters (day of the year, time of day, etc.), a model two-dimensional electron density distribution has been calculated using this model. When calculating this two-dimensional distribution of the electron density, changes have been made that transformed it into a distribution that most closely matches the real ionosphere, for example, the presence of a plasma ring, a trough, etc. Using the obtained distribution, some model quantities (differential phase and total electron content) have been calculated. Then they are used for model estimation of errors in the calculation of the TEC by the spaced reception method. For quite conditions in the ionosphere, the relative error of determining the initial phase constant does not exceed 3 %, and in the case of the plasma ring - 13 %. For the vertical total electron content, the relative error in quite conditions does not exceed 7 %, and in the case of a plasma ring - 60 %. Large values of the relative error are in areas of sharp change of the vertical total electron content.

Authors: Dikaeva D. R.
Published: June 2022

The northeast of the Barents Sea (the area between the Franz Josef Land and Novaya Zemlya archipelagos) is one of the little-studied areas characterized by a complex structure of the hydrological regime, bottom relief and bottom sediment structure. This area is characterized by the predominance of brown soils with a large number of foraminifera shells, which affects the species composition and structure of benthic communities. The species composition and quantitative characteristics of polychaetes in the northeastern part of the Barents Sea were analyzed on the basis of material collected in December 2019 during Murmansk Marine Biological Iinstitution expeditions on the r/v Dalnie Zelentsy . Faunal complexes of polychaetes have been identified in the study area depending on environmental conditions (type of bottom sediments, depth, hydrological conditions). In the areas of marginal troughs, the detritophagus Spiochaetopterus typicus dominates in terms of biomass and abundance, forming abundant settlements on soft silty-sandy, silty-clay soils. Low values of biomass and abundance have been noted on brown silts with a large number of foraminifera, dominated by Laonice cirrata . On the slopes of underwater hills, washed more strongly by bottom currents, on rough sandy soils with low nutrient content, the dominance of Nephtys ciliata has been noted. The species Sphaerodoridium kolchaki sp. n. recently encountered in the Barents Sea has been noted in the study area as well. The obtained data complement information on the species composition of the northeastern part of the Barents Sea and make it possible to trace further changes in the composition and structure of benthic communities.

The study of the realization of hereditary variability on the background of already existing mutant alleles of certain genes is an important part of biomedical and population investigations, including human diseases. The change in viability parameters in individuals of the wild type Belgorod and in the mutant strain of vestigial Drosophila melanogaster over the course of breeding has been researched. The changes in viability parameters during breeding have been recorded in hybrid individuals heterozygous for vestigial, namely, changes in fertility and embryonic lethality of offspring in hybrid individuals Belgorod × vestigial during direct selection, the presence of regulated cell death in the wing imaginal disc in individuals of the Belgorod and vestigial strains, and in hybrid individuals at the initial stage of breeding and after 30 generations of selection. The wing shape changes in interlinear hybrid individuals at different stages of breeding in relation to wild-type individuals Belgorod have been studied. The research methods are the following: selection, study of the frequency of death of offspring at the embryonic stage of development, fertility study, morphometric analysis of the wing, determination of the presence and location of regulated cell death in the wing imaginal disk, statistical analysis. The marker parameters of the wing sensitive to the presence of the mutant allele vg in the genotype, not associated with change in the intensity of regulated cell death in the wing imaginal disc have been revealed.

Authors: Faraci Palmira , Bottaro Rossella
Published: June 2022

Introduction: The impact of cancer represents a severe crisis for both patients and relatives. The implications of social support on well-being were well studied but several classifications have been proposed. Objective: The present cross-sectional study was aimed at examining the association between perceived social support (PSS) from family, friends, and significant other and psychological well-being (illness perception, life orientation, life satisfaction, and quality of life). Method: Participants were 138 cancer patients recruited during waiting time for medical treatment or examination, mostly diagnosed for more than six months. The Multidimensional Scale of Perceived Social Support, the Illness Perception Questionnaire, the Life Orientation Test-Revised, the Satisfaction with Life Scale, and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire were administered. Multiple regression analyses were performed. Results: Patients reported fatigue and loss of energy, and environmental pollution and change or bad luck as probable illness causes. Associations between (i) PSS from family and optimism, (ii) PSS from friends and personal control, coherence of disease, optimism, and physical functioning, (iii) PSS from significant other and life satisfaction were found. Conclusions: Our results revealed a specific role for each different PSS source.

Introduction: A cross-sectional descriptive study was conducted to evaluate the factor structure of Spanish translation and adaptation of the Cognitive Flexibility Inventory (CFI) in a sample of Colombian adults. Method: The sample of the study was n = 968. Respondents were aged between 18 and 52 years old (Mage=22.81, SD=4.42). Descriptive analyses, confirmatory factor analysis, and Cronbach’s Alpha calculation were carried out. Results: Internal consistency for the global scale was high (α=.89). Likewise, the coefficients of the Alternative factor and the Control factor were similar (α=.90, 95% CI=.89–.90 and α=.83, 95% CI=.81–.85, respectively). A two-factor structure performed best according to the results of model selection criteria. This model suggested the existence of two correlated factors, with correlated items within factors (Item19∼Item20 and Item8∼Item10). Conclusions: Overall, the results suggest that the CFI scale exhibits construct validity and adequate reliability, both for the general scale and the subscales in the Colombian sample, enabling their use in contexts such as clinical or research.

La contaminación del medio ambiente se ha convertido en una gran problemática, en una era donde la revolución industrial y el desarrollo tecnológico son predominantes y dominantes en la vida del ser humano, que lo ha llevado a un consumismo desmesurado. Problemática evidenciada en la industria del plástico, y que requiere buscar alternativas que permitan dar un nuevo uso a los plásticos descartados, retornándolos a la cadena productiva.
En este artículo se presentan resultados del proyecto que se desarrolló utilizando el polipropileno, procedente de tapas plásticas, en la elaboración de ladrillos de plástico, como material sostenible para la construcción de vivienda de interés social. Se comparó el comportamiento de estos especímenes con los ladrillos de arcilla convencional, con base en ensayos de laboratorio que permiten evidenciar un mejor comportamiento de los prototipos de plástico respecto a los ladrillos convencionales. Estos aspectos permiten ver la viabilidad del elemento con fines constructivos.

Spiritual capital is one of the essential intellectual capital that drives individuals and organizations to run the business following the law and standards. As a result, organizations can gain trust and integrity by following the rules and affecting their competitive advantages. This study analyzes competitive advantage based on spiritual capital, innovative work behavior, and organizational learning, which are reflected in two dimensions: exploratory and exploitative learning. The research population was 53 businesspersons of handicraft industries in the Malang City of Indonesia selected by saturated sampling techniques. A research instrument collected data in a structured questionnaire distributed to business people; the data were analyzed with SmartPLS 3.0. The results are interesting because they showed that spiritual capital did not significantly affect competitive advantage, both directly with a coefficient of 0.090 and as a mediator with a coefficient of 0.030 for innovative work behavior on competitive advantages. Other results of this study concluded that innovative work behavior was affected significantly by exploratory learning with a coefficient of 0.412 and exploitative learning with a coefficient of 0.139. Indirectly, exploratory and exploitative learning have a significant impact on spiritual capital with a coefficient of 0.139 for exploratory learning and 0.112 for exploitative learning. Spiritual capital was affected significantly by innovative work behavior with a coefficient of 0.331, and innovative work behavior affected competitive advantages with a coefficient of 0.371.

Authors: Karaçay Çiğdem
Published: June 2022

Boteh motifi, binlerce yıldır farklı kültürlerde çok çeşitli biçimlerde tasvir edilmiştir. Kelime olarak Farsçada “çalılık”, “yaprak demeti” veya “çalı yığını” gibi anlamlara gelmektedir. En genel formuyla soyut bir yaprağı andırmaktadır. Araştırmacılar tarafından motifin menşei ve sembolizmi ile ilgili çok farklı görüşler öne sürülmektedir. Ancak İslam öncesi ve İslam sonrası İran sanatında çok sayıda seçkin örneğine ulaşılan motifin İran kökenli olduğu ve servi ağacından köklendiği ortak kanı olarak görülmektedir. Bu çalışmada, evrensel bir motif olarak yüzyıllardır farklı toplumların kültür ve sanatlarında, 18. yüzyıldan itibaren ise özellikle İran ve Azerbaycan halı sanatlarında sıklıkla betimlenen boteh motifinin, Anadolu Türk halı sanatında tasvir edildiği örnekler tanıtılmakta ve gösterge bilimsel açıdan ifade ettiği anlam üzerinde durulmaktadır.

Türk dokuma kültürü içerisinde üretilen dokumalar zengin çeşitliliğe sahiptir. Dokumacı günlük yaşamı içerisinde yer yaygısı, heybe, torba, çuval, mafraş gibi farklı kullanım amaçları için çeşitli dokumalar üretmiştir. Bunlardan biriside “ölümlük-dirimlik” dokumalardır. Dokumacı bu dokumayı cenazesinin defni için götürülürken sarılması amacıyla dokuyup ya da başka bir kişiye dokutturup bir kenarda saklamaktadır. Genç kızların çeyizlerinde hem kendileri hem de eşleri için ölümlük-dirimlik dokumalar mutlaka bulunmaktadır. Bazen halı bazen de kilim, cicim ya da zili gibi farklı teknikli düz dokumalardan oluşan ölümlük-dirimlik dokumalar yöresel olarak “sargı kilimi” ya da “ahretlik dokuma” gibi farklı isimlerle bilinmektedir. Bu dokumalar mezarlık dönüşü ölen kişinin hayrına camiye bağışlanmaktadır. Bu çalışmada da günümüzde azalarak da olsa devam eden bu geleneğin önemli bir dokumacılık merkezi olan Burdur ve köylerinde sürdürülme biçimi ve bu amaçla yörede kullanılan dokumalar, bu dokumaların; kullanılan hammadde ve araç-gereçleri, dokuma tekniği ile renk, motif ve desen özellikleri incelenmiştir. Araştırma sonucunda 29 adet zili teknikli düz dokuma tespit edilmiştir.
