The influence of physical training on indicators of the functional state of the cardiovascular system of young boxers during the stage of initial training

Field: Medicine (Health Sciences)

The article is devoted to the problem of assessing indicators of the functional state of young martial artists (on the example of boxing). The goal is to investigate the dynamics of changes in the functional state of the cardiovascular system of young boxers during the stage of initial training. The research was conducted on the basis of "Complex Children's and Youth Sports School for Boxing and Martial Arts" of the DMR during 2021-2022. 35 young athletes participated in the research. It was established that in September 2021, the average group indicators of heart rate and average blood pressure corresponded to age norms; systolic and diastolic blood pressure indicators were higher than the age norm, pulse pressure indicators were lower. The assessment of the Robinson index indicated the predominance of a low level, which indicated the presence of signs of dysregulation in the activity of the CVS; in 80.0% of athletes, the state of adaptation was defined as "satisfactory adaptation". During almost a year of boxing classes (in December 2022), a repeated study confirmed the positive dynamics of the functional state of the CVS: the percentage of athletes who had an average level of the CVS condition increased statistically significantly to 83%, in 97.14% the state of adaptation was defined as "satisfactory adaptation".
Phased array measurement and simulation of vertical axis wind turbine noise

Field: Engineering (Physical Sciences)

Small scale vertical axis wind turbines are capable of capturing a large proportion of the energy contained in short period gusts of wind. This makes them ideally suited to operation in the turbulent wind environment found in built up areas. If wind turbines are to be installed in an urban area they will inherently be close to people meaning that noise is a particularly significant issue. Current understanding of the mechanisms of noise generation on vertical axis wind turbines is very limited. This study investigates the sources of noise using two methods. The principal approach uses a phased acoustic array to locate the noise sources on a model scale vertical axis wind turbine. These experiments are supported by aeroacoustic simulations of the sound field produced by a rotating point force representation of the wind tunnel model. Some initial results and conclusions are presented along with an outline of future investigations. The first initial conclusion is that the dominant noise source is in the upstream half of the rotor at tip speed ratios near 1 but moves to the downstream half as the tip speed ratio increases to 3. At these low tip speed ratios the noise is generated by fluctuations in the blade loads. At a tip speed ratio of around 5 the radiated noise is no longer due to blade loading effects and is now predominantly self-induced.

Conservation of transcriptional elements in the obligate symbiont of the whitefly Bemisia tabaci

Field: Agricultural and Biological Sciences (Life Sciences)

Background Bacterial symbiosis is widespread in arthropods, especially in insects. Some of the symbionts undergo a long-term co-evolution with the host, resulting in massive genome decay. One particular consequence of genome decay is thought to be the elimination of transcriptional elements within both the coding region and intergenic sequences. In the whitefly Bemisia tabaci species complex, the obligate symbiont Candidatus Portiera aleyrodidarum is of vital importance in nutrient provision, and yet little is known about the regulatory capacities of it. Methods Portiera genomes of two whitefly species in China were sequenced and assembled. Gene content of these two Portiera genomes was predicted, and then subjected to Kyoto Encyclopedia of Genes and Genomes pathway analysis. Together with two other Portiera genomes from whitefly species available previously, four Portiera genomes were utilized to investigate regulatory capacities of Portiera , focusing on transcriptional elements, including genes related with transcription and functional elements within the intergenic spacers. Results Comparative analyses of the four Portiera genomes of whitefly B. tabaci indicate that the obligate symbionts Portiera is similar in different species of whiteflies, in terms of general genome features and possible functions in the biosynthesis of essential amino acids. The screening of transcriptional factors suggests compromised ability of Portiera to regulate the essential amino acid biosynthesis pathways. Meanwhile, thermal tolerance ability of Portiera is indicated with the detection of a σ 32 factor, as well as two predicted σ 32 binding sites. Within intergenic spacers, functional elements are predicted, including 37 Shine-Dalgarno sequences and 34 putative small RNAs.
Metastatic Cavernous Sinus Meningioma: A Theory of Probable Predisposing Factor for Metastasis of Meningioma

Field: Medicine (Health Sciences)

Meningiomas are mostly benign, slowly-growing, non-metastatic, particularly limited to the central nervous system, however, they were occasionally reported for spreading to distant organs. While the risk factors still remain widely unknown for metastasis of meningiomas, the histopathological type and size of tumor are predicted to be predisposing factors for it. We aimed to discuss a possible new predisposing factor, which is contiguity of intracranial meningiomas to the dural sinuses, for metastasis to the body by presenting a case with metastatic cavernous meningioma and literature research. We presented a rare case that has been treated for cavernous sinus meningioma and then diagnosed with malign meningioma metastasis to the lung. We speculated that meningiomas adherent to the dural sinuses may be more inclined to distant organ metastasis, and they might use dural sinuses for seeding. This hypothesis can be likely verified by large case series, and this case report may inspire further investigations.
Factors Affecting the Readiness of Malaysian Schools toward ICT Management: A Theoretical Context

Field: Social Sciences (Social Sciences)

ICT is now widely adopted within the education system in Malaysia. As such, teachers are now required to integrate ICT into their teaching and learning practices. The integration of ICT requires organizational change and adequate supports from schools to create an ICT culture. However, underutilization of ICT elicits the issue of the lack of ICT management readiness in schools. This paper aims to analyze the possible factors of ICT management readiness. A number of relevant studies have been discussed in this paper. A few propositions and a theoretical framework for ICT management readiness are recommended for the attention of school principals.
The Implications of Coupling an Electron Transfer Mediated Oxidation with a Proton Coupled Electron Transfer Reduction in Hybrid Water Electrolysis

Field: Chemistry (Physical Sciences)

Abstract Electrolysis of water is a sustainable route to produce clean hydrogen. Full water‐splitting requires a high applied potential, in part because of the pH‐dependency of the H 2 and O 2 evolution reactions (HER and OER), which are proton‐coupled electron transfer (PCET) reactions. Therefore, the minimum required potential will not change at different pHs. TEMPO [(2,2,6,6‐tetramethyl‐1‐piperidin‐1‐yl)oxyl], a stable free‐radical that undergoes fast electro‐oxidation by a single‐electron transfer (ET) process, is pH‐independent. Here, we show that the combination of PCET and ET processes enables hydrogen production from water at low cell potentials below the theoretical value for full water‐splitting by simple pH adjustment. As a case study, we combined the HER with the oxidation of benzylamine by anodically oxidized TEMPO. The pH‐independent electrocatalytic oxidation of TEMPO permits the operation of a hybrid water‐splitting cell that shows promise to perform at a low cell potential (≈1 V) and neutral pH conditions.
Effect of bilateral carotid occlusion on cerebral hemodynamics and perivascular innervation: An experimental rat model

Field: Neuroscience (Life Sciences)

Abstract We aimed to investigate the effect of chronic cerebral hypoperfusion on cerebral hemodynamics and perivascular nerve density in a rat model. Bilateral common carotid artery (CCA) ligation ( n = 24) or sham‐operation ( n = 24) was performed with a 1‐week interval. A subgroup (ligated n = 6; sham‐operated n = 3) underwent magnetic resonance imaging (MRI) before the procedures and 2 and 4 weeks after the second procedure. After termination, carotids were harvested for assessment of complete ligation and nerve density in cerebral arteries that were stained for the general neural marker PGP 9.5 and sympathetic marker TH by computerized image analysis. Five rats were excluded because of incomplete ligation. MRI‐based tortuosity of the posterior communicating artery (Pcom), first part of the posterior cerebral artery (P1) and basilar artery was observed in the ligated group, as well as an increased volume ( p = 0.05) and relative signal intensity in the basilar artery ( p = 0.04; sham‐group unchanged). Immunohistochemical analysis revealed that compared to sham‐operated rats, ligated rats had increased diameters of all intracircular segments and the extracircular part of the internal carotid artery ( p < 0.05). Ligated rats showed a higher general nerve density compared to controls in P1 (10%, IQR:8.7–10.5 vs. 6.6%, IQR:5.5–7.4, p = 0.003) and Pcom segments (6.4%, IQR:5.8–6.5 vs. 3.2%, IQR:2.4–4.3, p = 0.003) and higher sympathetic nerve density in Pcom segments (3.7%, IQR:2.8–4.8 vs. 1.7%, IQR:1.3–2.2, p = 0.02). Bilateral CCA occlusion resulted in redistribution of blood flow to posteriorly located cerebral arteries with remarkable changes in morphology and perivascular nerve density, suggesting a functional role for perivascular nerves in cerebral autoregulation.
Mycorrhizal associations drive the tradeoff between plant biomass and soil carbon accumulations in forest ecosystems under N deposition and warming

Field: Environmental Science (Physical Sciences)

Abstract Forest ecosystems store ca. 80% of the carbon (C) in terrestrial ecosystems 1–2 , but their long-term C sequestration partly depends on how plant biomass and soil C stocks will respond to global changes. Although the stimulation of plant growth by global change drivers such as nitrogen (N) deposition, elevated CO 2, and warming has been widely observed 3–5 , the response of soil C stock to global changes remains uncertain. Here, we conducted a meta-analysis on 3050 pairwise observations of plant and soil C-related data from 372 experiments worldwide. We found that plant biomass and soil C stock increased more under elevated CO 2 than under N deposition and warming. Under N deposition and warming, soil C stock depended on mycorrhizal associations, decreasing in forests dominated by arbuscular mycorrhizal (AM) tree species while increasing in forests dominated by ectomycorrhizal (ECM) tree species. These results suggest a mycorrhizae-mediated tradeoff between plant biomass and soil C sequestration in forest ecosystems under N deposition and warming conditions.
Relationship between the genetic hemoglobin polymorphism, morphometry and fertility of Pramenka sheep breed from Central Bosnia

Field: Agricultural and Biological Sciences (Life Sciences)

The characteristics of these sheep are highlighted depth measures of external appearance with modest width measures. Another weaker feature of Pramenka sheep is poor fertility. Despite the mentioned disadvantages, Pramenka sheep is the most grown sheep in Central Bosnia and sheep production is based on it. Methodical selection to improve the characteristics of Pramenka sheep has not applied. However, sheep breeders tend to improve the qualitative and quantitative characteristics of sheep, and that means more intensive work on the selection. In this sense, genetic markers are used to carry out the selection lately. Three types of hemoglobin, HbAA, Hband HbBB of Pramenka sheep population (at 189 male and female animals) in Central Bosnia were segregated by the method of electrophoresis. The following genotype frequencies are determined: HbAA 0.11; Hb0.41; and HbBB 0.48. Allele frequencies, HbA and HbB for Pramenka sheep breed (estimate based on genotype frequencies) were 0.315 and 0.685. It was found that the population of sheep was in the equilibrium of the frequency of hemoglobin genotypes. Sheep with HbAA genotype had lower morphometric measures in relation to the other two genotypes. The statistically significant difference between sheep with Hbgenotype and HbAA genotype was recorded only for the shin perimeter. The ewes that lambed one lamb have the following frequency of HbAA, Hband HbBB genotypes: 0.13; 0.40 and 0.47, and the ewes with twins: 0.02; 0.40 and 0.58. Fertility, as important quantitative characteristic of sheep, was more emphasized in genotype HbBB, than in HbAA genotype. This was confirmed by the statistical analysis.

Field: Medicine (Health Sciences)

We report a rare case of chronic paracoccidioidomycosis(PCM) in a woman with Crohn disease in the setting of treatment with azathioprine and mesalazine. Serum tests for antigens to Paracoccidioides brasiliensis, Histoplasma capsulatum, and Aspergillus fumigatus were negative. An incisional biopsy of an oral lesion with periodic acid-schiff and Grocott-methenamine silver stains revealed chronic granulomatous inflammation with multinucleated giant cells with Paracoccidioides brasiliensis within the cytoplasm, confirming the diagnosis of PCM.
Potential Analysis and Development Strategies Based on Zoning For Beef Cattle Farming in Kepulauan Bangka-Belitung Province

Field: Agricultural and Biological Sciences (Life Sciences)

This research was aimed in detemining the potency mapping and development strategies based on zoning for beef cattle farming in Kepulauan Bangka Belitung Province. This research was implemented by using two-stages survey method. The first stage was analyzing and making regional potency mapping from secondary data with potential index analyses. The second stage was observing the results of the observation, an in-depth interview, and focus group discussion towards 42 respondents consisted of 14 cattle farmers, 5 cattle sellers, 5 agriculture agency officers, and 18 officials who were in charge of the cattle function in regency/city. Purposive sampling was used to choose respondents. Meanwhile, the data analysis used SWOT analysis. The results of potency mapping showed that Bangka had the highest index (the most potential). Pangkalpinang had the lowest index (potential). The qualitative SWOT analysis resulted in the strategy of SO (Strength-Opportunity), WO (Weakness-Opportunity), ST (Strength-Treat), and WT (Weakness-Threats). Qualitative analysis of SWOT showed the internal factor -0,153 (x) and external factor 0,34 (y). The strategies were in quadrant III; changing the policies by minimizing the weakness to take advantage of opportunities. The analysis for RTRW documents and the result of SWOT analysis generated 6 (six) zones and development priorities. Thus, the development plan of beef cattle consisted of priority zones: 1). I: production center and product processing in Bangka Tengah; 2) II: Cattle farmer integration in Bangka, Bangka Barat, and Belitung Timur; 3) III: Cattle farming in a previously ex-mining land in Bangka, Bangka Barat, and Belitung Timur; 4) IV: production center with local based feed production in Bangka Selatan; 5) V: Modern cattle farm with technology-based in Pangkalpinang; 6) VI: Animal farm with agrotourism based in Pangkalpinang and Belitung.
Resource allocation in MIMO systems specific to radio communication

Field: Computer Science (Physical Sciences)

The performance of the multi-input multi-output (MIMO) systems can be improved by spatial modulation. By using spatial modulation, the transmitter can select the best transmit antenna based on the channel variations using channel state information (CSI). Also, the modulation helps the transmitter to select the best modulation level such that the system has the best performance in all situations. Hence, in this paper, two issues are considered including spatial modulation and information modulation selection. For the spatial modulation, an optimal solution for obtaining the probability of selecting antenna is calculated and then Huffman coding is used such that the transmitter can select the best transmit antenna to maximize the channel capacity. For the information modulation, a multi quadrature amplitude modulation (MQAM) strategy is used. In this modulation, the modulation size is changed based on the channel state variations; therefore, the best modu- lation index is used for transmitting data in all channel situations. In simulation results, the optimal method is compared with Huffman mapping. In addition, the effect of modulation on channel capacity and a bit error rate (BER) is shown.
Mathematical Modeling of Electromagnetic Disturbances in Railway System

Field: Engineering (Physical Sciences)

By introduction of modern electronics into railway system, new challenges in understanding the electric and electromagnetic behavior of these systems arise. In this thesis, electromagnetic modeling of electric networks above dielectric and perfect electrically conducting surfaces are studied. The approach is based on the Partial Element Equivalent Circuit (PEEC) method for solving Maxwell's equations. The most challenging problem within electromagnetic modeling of large systems is computational speed and for railway systems, modeling of the ground becomes the major bottleneck. The purpose of the thesis is to develop maintenance program for the railway system in the northern Sweden to deal with the failures created by electromagnetic disturbances using mathematical modeling of the electromagnetic phenomena. First, a grid PEEC approach is used to improve the computation time of the original program. This approach utilizes an algorithm to distribute the calculations on computers in a local area network. It is shown that the computation time for large systems can be improved in some stages of the computation process. The second approach to improve the computational efficiency of the PEEC method utilizes the theory of complex images. This results in an appropriate mathematical tool to study and describe the generated electric fields above the earth, as a dielectric- or perfectly electric conducting surface. Different mathematical models are applied to analyze and plot the current distribution on structures and the electric field generated by several structures above a perfect electrical conducting surface. The tests are verified by analytical methods and the traditional PEEC computation method. In the traditional PEEC method, the numerical solution of mathematical modeling of the ground constitutes the major effort due to the large number of unknown variables in the corresponding linear equation system. By using of the complex image methods, where the effect of the ground is approximated, the computational time will clearly be improved in the case studies. This combination of the PEEC method and the method of complex images results into an ultimate linear equation system by a smaller number of unknown variables and therefore a considerable improvement of the computational time. By use of electromagnetic modeling, it will be possible to study the disturbances due to transients and discharges, and also to expand the data bases for artificial intelligence. Defining the problem and determining what can be obtained by using of computational electromagnetic modeling, will be a step towards developing a more appropriate maintenance program for the railway system in the northern Sweden.
The Experiences of Students with Mobility Disabilities in Cypriot Higher Education Institutions: Listening to their voices

Field: Social Sciences (Social Sciences)

This article explores the experiences of students with mobility disabilities in Cypriot higher education institutions. In order to obtain relevant information, in‐depth semi‐structured interviews were conducted with 10 Cypriot students with different forms of mobility disabilities, who attended different Cypriot higher education institutions and a variety of courses. This study yielded interesting results in terms of provision (e.g., accommodation for examinations and assignments, note‐taking services, tutorials, counselling services) as well as lecturers' and students' attitudes towards disability, raising interesting issues of social inclusion and rights. The quality of their experiences was affected by physical access, provision availability, positive responses by fellow students without disabilities, and the level of awareness among the members of the academic staff or the rest of the staff (e.g., cleaners, administrative officers, and accommodation staff). The findings of this study have implications at an institutional level for rethinking and refining policy and practice on disability.

The Scalenus Accessorious Muscle

Field: Medicine (Health Sciences)

Muchas de las variaciones anatomicas no estan suficientemente descritas o cuantificadas y son actualmente clinica y quirurgicamente significativas mas que curiosidades anatomicas. Reportamos una variacion anatomica en el grupo de los musculos escalenos, presente en un cadaver de una mujer de 56 anos. Este tipo de variacion puede afectar el tamano del triangulo escalenico y por lo tanto, puede potencialmente resultar en variados signos y sintomas en pacientes vulnerables al sindrome de salida toracica. La proximidad de los musculos escalenos con el plexo braquial, arteria y vena suclavias, coexistiendo con fasciculos aberrantes pueden predisponer a sindromes de compresion.
