Introduction: It is proposed that the use of the foam roller (FR) in the sports field can be a good complement to optimize the acute improvement of range of motion and to cause an analgesic effect, however, its use in warm-up to improve neuromuscular variables such as vertical jump is controversial in athletes. Therefore, the objective of this systematic review was to analyze the effects of FR on jumping ability in athletes. Material and method: A comprehensive, exhaustive, and structured search was carried out following PRISMA recommendations in the following databases: Pubmed/MEDLINE, Cochrane, Scopus, Sciencedirect and Web of Science. The studies that met the inclusion criteria were assessed for their methodological quality using the PEDro scale. Results: A total of 262 records were found in the study identification phase. In the screening phase, duplicates were eliminated, and the studies were filtered by selecting the title, abstract and keywords, obtaining 47 references as a result. A total of 18 studies were analyzed in full text, 12 of which were excluded. Therefore, the total number of studies that met all the selection criteria was six. Conclusions: The selected studies show that the application of RF is a technique that contributes to increasing the performance of jumping capacity in athletes and its effect can last up to 10 minutes after its application. However, protocols and duration times should be standardized to maximize results.

Introduction: Each development stage of the healthcare system and medicine is associated not only with the emergence of new integrated areas of knowledge, but also with radical changes in the technology of the doctor’s work with the patient, algorithms, methods for collecting, processing information, and making decisions. Also, many postulates need revision, activation of existing reserves, certain concepts also require a new interpretation. Objective: To form a high-quality medical model for the rehabilitation of highly qualified athletes. Material and method: The paper proposes a model for constructing a quality assessment of rehabilitation of athletes based on probabilistic methods. The novelty of the study underlies the transition from a qualitative to a quantitative assessment of health, which has become a new direction in the assessment and management of health. Results: The authors present a model of a qualitative increase in the managerial process by the rehabilitation of highly qualified athletes. The paper proves that it is necessary to determine the ability to measure and express the basic properties of any organism in conditionally qualitative proportions – the ability to withstand various stressful effects and adverse environmental influences. Conclusion: The practical significance of the study is determined by the fact that it is necessary to search for evaluative health criteria, and in the individual’s ability to carry out biological and social functions. The perfection of these functions in humans can also be described quantitatively, by reserves of energy, plastic, and regulatory support of functions.

Published: April 2023

Nas escolas no Campo encontram-se diferentes tipos de agrupamentos e organizações de sala de aula que resistentemente, diante de tantas contingências, proporcionam educação às crianças. A partir do problema de: como são organizados os agrupamentos de multiidade e multisseriação nas escolas no Campo, este texto se propõe investigar como são organizados esses agrupamentos nas escolas no Campo. Com uma natureza exploratória, este estudo se configura como uma revisão de literatura, tendo como aporte teórico textos que discutem o tema visitado, com destaque para os trabalhos de Barbosa e Fernandes (2013), Hage (2011), Janata e Anhaia (2015), João (2018), Oliveira e Oliveira (2017), Prado (2006), Rego (1995). Os agrupamentos de Multiidade no contexto do Campo constituem-se organizações que agrupam crianças com idades diferentes em uma sala de atividade, por conta da pouca demanda em cada nível, insuficiente quantidade de salas de atividade ou docentes disponíveis, dentre outras necessidades, com ausência de uma proposta pedagógica específica e legítima a esse tipo de agrupamento. As classes multisseriadas no Campo ao reunir alunos de diferentes séries escolares em um mesmo espaço físico de sala de aula, também se configura como ajuste/arranjo imposto à prática docente e a aprendizagem discente por conta das contingências existentes nas escolas no Campo. A nucleação, enquanto um modo de organizar, aparece como uma alternativa para auxiliar nessa conjuntura, porém, em muitos aspectos também se configura como uma proposta sem muita consistência pedagógica.

Published: April 2023

Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) causes coronavirus disease 2019 (COVID-19) with clinical outcome ranging from asymptomatic to severe disease, and even death to some. It posed a terrifying challenge to healthcare system worldwide. Several observational and clinical trials has reported that, Vitamin D deficiency has contributed to acute respiratory distress syndrome. Case fatality rate increases with age and comorbidities, both of which are associated with decreased Vitamin D level. Therefore, this study is done to study the prevalence of 25(OH)Vitamin D in RT-PCR positive COVID-19 cases and RT-PCR negative controls.

This is a hospital based cross-sectional study conducted at Jawaharlal Nehru Institute of Medical Sciences, Manipur on 88 RT-PCR positive Covid-19 cases and 88 COVID-19 negative controls over a period of 2 years. Analysis of the sample was done by Liaison 25(OH) Vitamin D Total Chemiluminescence assay(CLIA).

In this study, statistically significant (p-0.018) lower plasma 25(OH)Vitamin D level is seen in COVID-19 positive cases (median 28±20.47) when compared to Covid-19 negative controls(median 33.50±10.66). The number of 25(OH) Vitamin D deficient is higher in Covid-19 positive cases when compared to Covid-19 negative controls -46(52.3%) and 30(34%) respectively with a high statistically significant value (p-0.015).

COVID-19 positive cases have higher tendency to have suboptimal plasma 25(OH) Vitamin D level which may contribute to the high hospitalization risk in COVID-19 infection. This finding is important as it can identify population at risk, and contribute to interventions in reducing the risk of hospitalization associated with COVID-19 infection.

Published: April 2023

Quality assurance is need of the hour in a laboratory. Clinician’s decision regarding treatment modality is based on the laboratory results on most occasions. So to ensure accuracy of results reported periodic evaluation as per standard criteria and audit is necessary. Six sigma is one such tool to apply in day to day practice for monitoring and enhancing performance of a laboratory. A new machine is a new challenge for a laboratory from validation to reporting of quality result with assurance for which six sigma is invariably a necessary method. So this study was taken up to check for month wise status of six sigma and performance of clinical chemistry analyser for 20 different analytes.

: It was a retrospective study and data required for the study were collected from March 2020 to November 2020 in clinical biochemistry laboratory of Tata Medical Centre Kolkata, West Bengal. Test parameters were analysed on Vitros 7600 automated analyser. Data collected were IQC-coefficient of variation percent (CV %) and proficiency test -Bias%. Six sigma score were analysed monthly using standard formula applicable.

We obtained an excellent performance (> 6 sigma) for test parameters CK, Urea, Creatinine, Uric acid, albumin, Calcium, Phosphorus, Magnesium, AST, ALTV, ALKP, GGT, Lipase, LDH in both level of IQC and for sodium and amylase in level 2 IQC. However we noticed poor performance (<3 sigma) for test parameters Glucose, potassium, chloride, TP in both level IQC and for sodium and amylase in level 2 IQC.QGI score analysed to find out root cause and corrective action.

Monitoring IQC and EQAS with six sigma method helps evaluation and improvement of performance of a laboratory even with a new machine. It supports root cause analysis and necessary corrective and preventive action.

Authors: Anjum Arshiya , Bagade Sanjay , Boyella Pavan Kumar
Published: April 2023

: Monoclonal gammopathy include several clinical variants ranging from asymptomatic MGUS, asymptomatic smouldering myeloma, multiple myeloma to aggressive plasma cell leukemia. The characteristic property of myeloma cells is the production and secretion of M protein. Due to its diverse structure, no single test can identify M protein accurately in all patients. A simple, non-invasive combination of tests is necessary for the screening of monoclonal gammopathy.

The present study aims to assess the diagnostic sensitivity of the biochemical tests used in the screening of monoclonal gammopathy.

: This study was conducted retrospectively of the newly diagnosed cases of monoclonal gammopathy screened with SPE and ISUB/IT using sebia capillary electrophoresis and serum free light chain ratio using immunoturbidimetry method.

: Out of the 142 patients included in the study, 120 had M band in SPE, 125 had monoclonal gammopathy by ISUB/IT and 121 patients had abnormal sFLCR. The diagnostic sensitivity obtained was 84.5% 88% and 85.2% for SPE, ISUB/IT and sFLCR respectively. Addition of sFLCR to SPE and ISUB/IT could identify 20 patients who had no abnormality in either of these tests. The combined sensitivity of SPE and ISUB/IT was 88%, while that of SPE and sFLCR and a combination of all the three tests was 98.6%.

The simple, non-invasive, cost-effective screening panel of SPE plus sFLC ratio could be used as the initial screening method for patients with suspected monoclonal gammopathy with increased reliability.
They lied to them at every word": lie in the communication system of Russian peasants and landlords in the late 18th — early 20th centuries
Authors:   Belgorod State National Research University, Shapovalov Vladimir A. , Istomina Irina V. ,   Belgorod State National Research University
Published: April 2023

The article deals with the lie as communicative phenomenon in the context of manipulative communication between peasants and landowners both in the pre-reform and post-reform periods. The authors highlight the reasons for the widespread use of lies by peasants, ranging from the desire to get something fraudu-lently from the landlords and ending with the evasion of corvée work or their poor-quality performance. Within the framework of manipulative communication, a lie was a convenient tool, since it was not always possible to quickly verify false information or ex-pose it at all. Lies were also a “weapon of the weak”, when real resistance was hidden behind pretense and hypocrisy (rumors, gossip, labeling, etc.).

In order to meet the needs of the fishing function, the overall structure of the surface floating object fishing device was bionically designed by combining the large beak and flexible neck of the pelican, The innovative design of the mouth lower beak opening and closing mechanism, the lower beak gear rack lever slide mechanism, the mouth throat pouch bottom release mechanism and the neck structure are mainly carried out.The structural strength of the device under the most dangerous operating conditions was simulated using finite element analysis software for statics and dynamics simulation. The research results show that the structure of this design is reliable, and the experimental test of the prototype model verifies the validity and reliability of this design scheme, which provides the theoretical and experimental basis for the further development of the subsequent products.
Examen de la teoría aimarista de Uhle
Authors: Cerrón-Palomino Rodolfo
Published: April 2023

Dentro de la historiografia andina relativa a la etapa preincaica, son conocidas las tesis antagónicas del quechuismo y del aimarismo primigenios de la civilización megalítica de Tiahuanaco (cf. Porras Barrenechea 1963, cap. 11, 22-23). Las teorías propuestas buscaban responder, básicamente, las mismas interrogantes que se formulaba a mediados del siglo XVI el muy ponderado e inquisitivo cronista Cieza de León (ver epígrafe), "espantado", como diría él, ante la magnificencia de los monumentos tiahuanacotas. 1 Tales preguntas, en efecto, giraban en torno a éstas: ¿qué pueblo (o "raza", como se decía entonces) habría sido el constructor de tales prodigios? ¿Serían los quechuas (mas no necesariamente los incas) o los aimaras~ que compartían el mismo espacio que había visto florecer tan asombrosa civilización? ¿Cuál habría sido la lengua originaria de los auténticos creadores de aquélla? ¿Sería la quechua, la aimara, u otra diferente, puesto que, además de estas lenguas, había por Jo menos otra que aún se hablaba la uruquilla- en territorios cotérminos?

Authors: Akumbom Paul , Egwu Mary Juliet Bime , Shillie Peter Ngek
Published: April 2023

Purpose — Often people's hesitation to accept new technology stems from a misconception of what technology truly entails. Pictures of future robots and robotics typically spring to mind when people think of technology. Many poor nations rely heavily on agriculture for their survival. Most of the world's impoverished population works in agriculture and lives in rural regions. Indirectly and directly, it contributes to expanding industries and providing food for the world's population. This paper investigates the effects of agricultural technology adoption on poverty reduction.Method — The study adopted both the survey and causal research designs. The researcher employed purposive and snow ball sampling techniques. A total of 384 households were sampled for the study. Data for this study was gotten with the help of a structured questionnaire from household in Tubah Sub-Division of Cameroon and was analysed using inferential statistics.Result — This study revealed that consumable and durable inputs significantly positively affect agricultural productivity in the sub-division at 1% and 5% degree of significance respectively. The results further showed that agricultural productivity had a mediating positive effect on poverty reduction at 1% degree of significance.Contribution — Most studies on agricultural technology adoption in developing countries only focus on short-term impacts. In contrast, this study provides information on the long-term effects of technology adoption on farmers' livelihoods and the environment.

Published: April 2023

Introduction: With increasing global concerns about the prevalence of COVID-19, chest imaging findings are essential for effective diseases diagnosis and treatment. There is a need to distinguish between imaging features of COVID-19 pmeumonia and other viral pneumonia like Influenza.For this purpose, a study was performed on a comparison of chest CT findings between COVID-19 pneumonia and Influenza pneumonia. Methods: Fifty patients with respiratory symptoms and positive real-time PCR (RT-PCR) of nasopharyngeal swab for Influenza and fifty patients with respiratory symptoms and positive real-time PCR (RT-PCR) of nasopharyngeal swabfor COVID-19 from March to May 2020 were enrolled in the study. In the patient’s checklist, information such as demographic characteristics (age, sex), laboratory findings including (CRP, ESR, WBC), and clinical signs (fever, cough, fatigue, dyspnea) were also recorded. Results: Gastrointestinal symptoms, anorexia, high CRP, ground-glass opacityare more common in patients with COVID-19 pneumonia than in patients with influenza pneumonia and this difference was statistically significant (P <0.05). But, fever is more common in influenza patients than in Covid-19 patients and this difference is statistically significant (P=0.029). The location of CT scan findings in COVID-19 patients was dominant in peripheral (54 %), while the location of CT scan findings in patients with Influenza was dominant in central (32 %), which is statistically significant (P <0.05). Conclusion: According to the results of the study, lung CTscan findings along with some clinical and laboratory findings can help differentiate COVID-19 pneumonia from influenza pneumonia, which is very important in faster diagnosis and timely treatment of both diseases.

The article provides the description of three clinical cases for demonstration of difficulties of coxiellosis diagnosis with analysis of serological profiles, titers and avidity of antibodies. Conclusion: the results of the study indicate that negative results of PCR testing do not exclude C. burnetii infection. For patients who, according to clinical and epidemiological data, Q fever is not excluded, it is advisable to prescribe a complex of laboratory tests to verify the diagnosis, which includes not only studies of the pathogen’s DNA, but also specific antibodies. To clarify the stage of the disease and reduce the risk of developing complications of coxiellosis, it is necessary to monitor the dynamics of antibody titers to C. burnetii in phase I and II phase states differentially.

The combination of chronic coronary heart disease and type 2 diabetes mellitus in a patient has high medical importance, because relevance of the problem increases every year. Modern requirements for the provision of high-quality medical care to patients with combined pathology require attentive assessment: we can’t deny the pathophysiological relationship of both diseases. Serious changes that occurred in the treatment tactics in relation to such patients require close attention of the medical community. Modern approaches of the therapy of this group of patients include treatment directions that improve the cardiovascular prognosis (lifestyle changes, anti-platelet therapy, antihypertensive therapy, statins and nonstatin lipid-lowering agents, which are indicated for patients who are difficult to tolerate statin treatment, glucose-lowering drugs), as well as careful management of stable angina syndrome (using of antianginal drugs, assessing the possibilities of revascularization). The therapeutic tactics of the new revision offers promising perspective regimens for taking antiplatelet therapy, lipid-lowering drugs. The new line of glucose-lowering drugs has high cardioprotective properties, reduces the intensity of vascular lesions (vasoprotection), and has renoprotective properties. The strategy of choosing glucose-lowering drugs has also undergone some changes: at the moment it is designated as «differentiated», which implies choosing a drug with the highest organoprotective properties. Achievement of target HbA1C levels in the range of 7.0-8.0 % is associated with the lowest patient mortality rate. In addition, to patients with type 2 diabetes mellitus, especially group with coronary heart disease, advised to minimize episodes of hypoglycemic conditions. Aim of this statement is to discuss in detail progressive approaches in the treatment of patients with chronic coronary heart disease and type 2 diabetes mellitus.

Complexity of cellural decoders with repeating inputs
Authors: Zizov Vadim Sergeevich
Published: April 2023

The cellular schema model (CS) was first proposed in 1967 by S.S. Kravtsov, who also obtained the order of the Shannon function for it. Model CS is a mathematical model of integrated circuits (IC), taking into account features of physical synthesis. Presence of requirements for geometry schemes that ensure that the necessary routing resources are taken into account when creation of IP, represents a fundamental difference from good studied classes of circuits from functional elements (SFE). Similar mathematical model in foreign sources was described in 1980 K.D. Thompson. For IP-related studies, the model is fundamental, and is considered a satisfactory approximation for IS, at least for single crystal systems. Moreover, she remains an accurate approximation for small areas (individual components) IP in cases where the model cannot correctly reflect all features of the designed systems. In this work asymptotic estimates for the area of cellular schemes are established, implementing a decoder of order n with repeated inputs.

On restoration of a diagram of automata by its graph
Authors: Babin Dmitry Nikolaevich , Ishchenko Roman Andreevich
Published: April 2023

If in the transition diagram of an automaton we remove information about the input letters, we get a directed graph. Up to renaming the letters of the input alphabet, we solve the inverse problem restoring the automaton diagram from a digraph. Usually the number solutions turns out to be large, but sometimes it can be done unambiguously. The problem arises to find an algorithm for checking the existence of a solution, and also estimate the number of solutions in the worst case depending on the type automatic transitions.

Restoration of convex CPL-functions by neural nets over RELU bases
Authors: Shishlyakov Vladimir Gennadievich
Published: April 2023

The paper considers the issue of representing convex piecewise linear functions in the form of neural networks with activation functions RELU type and neural networks with a single non-linearity - so called the max-pooling layer. This question is in support of proof of a more general representation problem for any piecewise linear function in the form of a neural network over these bases. This problem is also solved, but so far the results obtained are under review, so it was decided to make emphasis on an intermediate, but no less important result. Also in work numerical characteristics are given that evaluate the quality of the obtained neural networks - non-linear complexity and depth.
On dyagnostic tests for mirror reflections of circuit inputs
Authors: Albek Madi Kairatuly , Romanov Dmitry Sergeevich
Published: April 2023

A single local mirror reflection of circuit inputs is understood as a malfunction consisting in the fact that within a certain segment consecutive inputs of the circuit, the order of the inputs of the circuit changes to opposite. With multiple local mirror reflections of the inputs scheme, the source of faults is chosen by an arbitrary number pairwise non-intersecting segments of consecutive inputs of the circuit, in each of which the order of the inputs of the circuit changes to opposite. The paper establishes the order of growth of the Shannon function length of a single diagnostic test relative to local mirror reflections of circuit inputs, as well as nontrivial evaluation of the Shannon function of the length of the complete diagnostic test with respect to local mirror reflections of circuit inputs.
