Published: November 2021

It is shown that electron tunneling through a potential barrier that separates two quantum dots of germanium leads to the splitting of electron states localized over spherical interfaces (a quantum dot – a silicon matrix). The dependence of the splitting values of the electron levels on the parameters of the nanosystem (the radius a quantum dot germanium, as well as the distance D between the surfaces of the quantum dots) is obtained. It has been shown that the splitting of electron levels in the QD chain of germanium causes the appearance of a zone of localized electron states, which is located in the bandgap of silicon matrix. It has been found that the motion of a charge-transport exciton along a chain of quantum dots of germanium causes an increase in photoconductivity in the nanosystem. It is shown that in the QD chain of germanium a zone of localized electron states arises, which is located in the bandgap of the silicon matrix. Such a zone of local electron states is caused by the splitting of electron levels in the QD chain of germanium. Moreover, the motion of an electron in the zone of localized electron states causes an increase in photoconductivity in the nanosystem. The effect of increasing photoconductivity can make a significant contribution in the process of converting the energy of the optical range in photosynthesizing nanosystems. It has been found that comparison of the splitting dependence of the exciton level Eех(а) at a certain radius a QD with the experimental value of the width of the zone of localized electron states arising in the QD chain of germanium, allows us to obtain the distances D between the QD surfaces. It has been shown that by changing the parameters of Ge/Si heterostructures with germanium QDs (radius of a germanium QD, as well as the distance D between the surfaces of the QDs), it is possible to vary the positions and widths of the zones of localized electronic states. The latter circumstance opens up new possibilities in the use of such nanoheterostructures as new structural materials for the creation of new nano-optoelectronics and nano-photosynthesizing devices of the infrared range.

Published: November 2021

Este artículo presenta los modelos evaluativos para intervenciones complejas en salud. Dichas intervenciones se caracterizan por ser dinámicas, altamente influen- ciadas por el contexto (político, social, económico y cultural), y cuentan con múlti- ples actores y multicomponentes. Las intervenciones complejas en salud se ejecutan simultáneamente con otras intervenciones de otros sectores; requieren tiempo para mostrar resultados y a veces es difícil estimar su contribución social e individual a la población blanco. Este artículo pretende identificar los modelos evaluativos propues- tos para intervenciones complejas en salud con sus respectivas características, a fin de tener referentes teóricos para evaluaciones de programas de esta naturaleza. Por mucho tiempo las intervenciones en salud y su evaluación se entendieron de manera lineal; sin embargo, bajo la perspectiva teórica de la complejidad (en la que se integran múltiples dimensiones del fenómeno), el contexto tiene un papel central. Esto permite entender que las intervenciones no tienen el mismo resultado en diferentes espacios y que esta forma de evaluación permite dar cuenta de ello.

Published: November 2021

This report aims to analyze the impact of state grants upon the effectiveness efficiency of the enterprises in the Agricultural sector. The presence/absence of the correlation between the “received state grants - financial results from the activity of the agricultural enterprises” was studied. The efficiency of agricultural enterprises is expressed through the indicators of profitability and productivity. The empirical data for a period of 10 years 2008 – 2017 were shown in the study. The main activities of the surveyed enterprises are crop, livestock and combined - crop-livestock. Based on the results obtained, it is expected that the receipt of grants will have a positive influence on the performance of enterprises in the agricultural sector, measured by indicators of effectiveness and productivity. The following research hypotheses have been proved: the positive effect of the grant is more obvious in larger agricultural enterprises, which have higher productivity and profitability compared to small and medium-sized farms; agricultural enterprises which receive grants and are characterized by higher investment activity and are also characterized by higher innovation activity; based on the predominant number of crop enterprises, it is assumed that this type of activity leads to the achievement of higher financial results as a result of the activity of the agricultural enterprises; the age of the enterprises, expressed through the years of their activity, contributes significantly to higher profitability and productivity of the carried out activity.

Non-occlusive mesenteric ischemia is a relatively rare but extremely complex pathology in terms of diagnosis. A wide range of reasons for the development of non-occlusive impression dramatically complicates the diagnosis and differentiation with other abdominal pathology. The vast majority of publications in the domestic literature on acute disorders of mesenteric blood flow, mostly address the problems of diagnosis and treatment of occlusive types of mesenteric ischemia, while the topic of non-occlusive ischemia remains insufficiently covered. Given that in half of the cases NOMI is diagnosed at the stage of irreversible necrotic changes of the intestine – there is a real need to generalize the root causes and mechanisms of neoclustive mesenteric ischemia, modern methods of diagnosis and treatment. Purpose – to analyze of the causes, prevalence, classification, diagnosis and treatment of non-occlusive disorders of mesenteric blood flow. This research, based on literature review, showed that acute non-occlusive mesenteric ischemia (NOMI) is associated with poor prognosis due to the lack of accurate diagnostic measures. First of all, clarity regarding biochemical markers. Therefore, the research and development of the latter is seen as a priority. Contrast methods of examination (computed tomography, angiography) are the only possible diagnostic tools. Pharmacological correction is fundamental and presupposes the use of drugs with a vasodilating effect systemically or locally (catheter-associated). An important issue is the development of pharmacological agents that allow targeted action on the pathogenetic mechanisms of the development of NOMI. A multidisciplinary approach involving a specialized doctor, a surgeon, an X-ray endovascular surgeon and an intensive care physician in the treatment of a patient with suspected NOMI is the foundation for the success of therapy. The question of the use of laparoscopy remains controversial, given the invasiveness of the method and the difficulty of interpreting the changes detected in the early phase of the disease. No conflict of interests was declared by the authors. Key words: acute mesenteric ischemia, non-occlusive disorders of mesenteric blood flow.

Duplication of the urethra is a rare abnormality that can occur with other urogenital tract congenital pathologies. Ischemia at embryogenesis, urogenital sinus defect, Muller`s duct anomaly and incomplete mesodermal fusion are the pathophysiological mechanisms of the pathology onset. Duplication of the urethra diagnostics is based on clinical examination, disease anamnesis, urethrography and magnetic resonance imaging. It is nessessary to consider Effmann and Leibowitz classification, urethras and prostate location and urethral orifice distance on operation of additional urethra removing. Clinical case. Presenting a clinical case of a boy with grade I epispadias and complete duplication of the urethra. Urination was maintained and was performed from the dorsal-epispadic urethra, the ventral urethra was obliterated in the distal region. According to the data of magnetic resonance imaging: double urethra is traced, dorsal – comes out from the anterior parts of the bladder wall, continues along the dorsal surface under the dorsal neurovascular bundle, above the cavernous bodies. The urethra opening is traced at the level of the upper surface of the head of the penis. The distal / ventral urethra comes out from the posterior parts of the lower bladder wall, typically continues down through the prostate embryo, rotated forward between of the corporas cavernosas stipes, and had a typical location with except for the level of the penis head, where it bends and merges with the dorsal urethra, which opens with a single opening. The surgery of excision of an additional urethra on child was performed. During the examination of the child of 6 months after surgery: urination with one stream from the ventral urethra at the apex of the head of the penis, stream freely passes the Nelaton catheter No. 10, child holds urine, there was no complaints. Performing of the next stage of the operation (penis plastic surgery) is planned after 1 year of the previous stage. Conclusions. In cases of epispadias is possible a congenital defect – a complete douplication of the urethra with the ventral urethra obliteration at the top of the head, which may not be determined in epispadias surgery preparation. Doubling of the urethra in boys requires magnetic resonance imaging for a better orientation in the defect anatomy and to determine the tactics of further surgical treatment. The research was carried out in accordance with the principles of the Helsinki declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: complete duplication of the urethra, surgical treatment, children.
RD-projective module whose subprojectivity domain is minimal
Authors: DURĞUN Yilmaz
Published: November 2021

A p-indigent module is one that is subprojective only to projective modules. An RD-projective module is subprojective to any torsionfree (and flat) module. An RD-projective module $T$ is called rdp-indigent if it is subprojective only to torsionfree modules. In this work, we consider the structure of SRDP rings whose (simple) RD-projective right $R$-modules are rdp-indigent or torsionfree. Moreover, new characterizations of P-coherent rings and torsionfree rings are presented by subprojectivity domains.

We introduce bi-slant $\xi^{\perp}$-Riemannian submersions from Sasakian manifolds onto Riemannian manifolds as a generalization of slant and semi-slant $\xi^{\perp}$-Riemannian submersion and present some examples. We give the necessary and sufficient conditions for the integration of the distributions used to define the bi-slant $\xi^{\perp}$-Riemannian submersions and examine the geometry of foliations. After we obtain necessary and sufficient conditions related to totally geodesicness of such submersion. Finally we give some decomposition theorems for total manifold.
High order approach for solving chaotic and hyperchaotic problems
Authors: ADIYAMAN Meltem
Published: November 2021

In this work, the method of Taylor's decomposition on two points is suggested in order to find approximate solutions of chaotic and hyperchaotic initial value problems and to analyze the behaviors of these solutions. Unlike to the classical Taylor's method, the proposed numerical scheme is based on the application of the Taylor's decomposition on two points to the system of nonlinear initial value problems, and as a result an implicit method is obtained. Stability and error analysis of the method are presented, and its high-order accuracy and A-stability are proven. One of the advantages of the proposed method is that it is a stable and very efficient method for chaotic problems as it is an implicit one-step method. The most important advantage of the Taylor's decomposition method is that it has high order accuracy for large step sizes with a simple algorithm compared to other methods. The applicability of the proposed method has been examined in some famous chaotic systems; the Lorenz and Chen systems, and hyperchaotic systems; the Chua and Rabinovich-Fabrikant systems, to emphasize both its accuracy and effectiveness. The accuracy of the proposed method is checked by comparing the calculated results with semi-explicit Adams-Bashforth-Moulton method and ninth order Runge-Kutta method. The calculated results are also compared with multi-stage spectral relaxation method and multi-domain compact finite difference relaxation method. Comparisons have shown that the method is more accurate and efficient than the other mentioned methods for large step sizes. The obtained results are also compared with the theoretical findings and it is shown that the theoretical and numerical results are consistent.

Published: November 2021

A $C$-semigroup (respectively a $D$-semigroup) is a positioned numerical semigroup $S$ such that $\rm{g}(S)=\frac{\rm{F}(S)+\rm{m}(S)-1}{2}$ (respectively $\rm{g}(S)=\frac{\rm{F}(S)+\rm{m}(S)-2}{2}$). In this paper we study these semigroups giving formulas for the Frobenius number, pseudo-Frobenius number, and type. Furthermore, we give algorithms for computing the whole set of $C$-semigroups and $D$-semigroups.
Diamond alpha Hardy-Copson type dynamic inequalities
Authors: KAYAR Zeynep , KAYMAKÇALAN Billur
Published: November 2021

In this paper two kinds of dynamic Hardy-Copson type inequalities are derived via diamond alpha integrals. The first kind consists of twelve new integral inequalities which can be considered as mixed type in the sense that these inequalities contain delta, nabla and diamond alpha integrals together. The second kind involves another twelve new inequalities, which are composed of only diamond alpha integrals, unifying delta and nabla Hardy-Copson type inequalities. Our approach is quite new due to the fact that it uses time scale calculus rather than algebra. Therefore both kinds of our results unify some of the known delta and nabla Hardy-Copson type inequalities into one diamond alpha Hardy-Copson type inequalities and offer new Hardy-Copson type inequalities even for the special cases.

Published: November 2021

ABSTRACT Background: Ischemic stroke (IS) is a multifactorial disease that presents high rates of morbimortality in Brazil. Several studies proved that there is a link between the ABO blood group system and the occurrence of thrombotic events. Nonetheless, its association with IS is not well established. Objective: For that reason, the purpose hereof was to investigate the relation between the ABO blood groups and the occurrence of IS in a Brazilian cohort of cerebrovascular diseases. Methods: Five hundred and twenty-nine subjects were included over 12 months, from which 275 presented an IS episode and 254 composed the control group. Blood samples were drawn for direct and reverse serotyping. The control and IS groups were compared regarding the traditional risk factors and the distribution of the ABO blood groups. Results: The IS group presented a higher prevalence of systemic arterial hypertension (SAH), diabetes mellitus, smoking habits, family history, cardiopathy, and sedentary lifestyle in comparison with the control group. The AB blood type prevailed among the patients (5.1 vs. 1.6%; p<0.05) and this group had more SAH cases in comparison with the O type group (92.9 vs. 67.3%; p<0.05). Conclusions: Our results suggest that the occurrence of IS is more frequent among patients of the AB blood type.

ABSTRACT Objectives: to identify factors associated with specific health-related quality of life in cerebrovascular accident, or stroke, survivors. Methods: cross-sectional study, carried out with 160 cerebrovascular accident survivors. Data were collected using the Barthel Index, Cerebrovascular Accident Specific Quality of Life Scale, and semi-structured instruments for sociodemographic and clinical data, analyzed by descriptive and inferential statistics. Results: health-related quality of life was associated with work activity (p=0.027), physical activity (p=0.007), functional capacity (p=0.001), presence of caregiver (<0.001), motor alteration (p = 0.001) and rehabilitation (p=0.003). The functionally dependent people were 14.61 times more likely to present low health-related quality of life, and those with motor impairment were 3.07 times more likely. Conclusions: it was evidenced that functional dependence and motor impairment increase the chance of low health-related quality of life in cerebrovascular accident survivors.

ABSTRACT Objective: Bibliometrics is a group of statistical and mathematical methods employed to measure and analyze the quantity and the quality of scientific articles, books, and other forms of publications. The objective of the present study was to conduct a bibliometric analysis of the Jornal Brasileiro de Psiquiatria (JBP) by listing its 100 most highly cited articles in the scientific literature and identifying their main characteristics in terms of authorship and research topics and design. Methods: The 100 top-cited references in the JBP were identified through a search with Google Scholar. The main author, last author, corresponding author, the total number of authors, gender of the authors, year of publication, research institution, geographic origin, language, and the research design and subject of each reference were recorded and analyzed. Results: A marked increase in the number of citations in the last 15 years, a relatively balanced distribution of publications among the Brazilian states and research centers, absence of gender bias among authors, and a varied range of published topics suggest a good current editorial performance by the JBP. Relative lack of systematic reviews and longitudinal studies, dearth of articles published in the English language, and modest participation of foreign authors were points requiring improvement. Conclusion: The present study suggests that a survey of the 100 most cited articles in the JBP can provide a historical overview of the progress of this journal, as well as highlight the main obstacles, constraints, and challenges faced by its editors and authors.

RESUMO Objetivo: Investigar a associação de horas diárias de trabalho e de descanso com o uso de substâncias psicoativas entre motoristas profissionais de caminhão. Métodos: Estudo transversal conduzido em 2016 com 354 motoristas profissionais de caminhão que aguardavam a inspeção da mercadoria transportada em um Posto de Controle Fiscal localizado na cidade de Itatiaia, RJ, Brasil. A associação entre horas diárias de trabalho (exposição), horas diárias de descanso (exposição) e uso de substâncias psicoativas (desfecho) foi investigada por meio de modelos de regressão linear que estimaram coeficientes de regressão (β) e respectivos erros-padrão,considerando p< 0,05. Resultados: Mostraram-se positivas as associações entre horas diárias de trabalho e uso de anfetamina (β = 0,91; erro-padrão = 0,19; p< 0,01) e de cocaína/crack (β = 1,32; erro-padrão = 0,35; p< 0,01) e negativa a associação entre horas diárias de descanso e uso de anfetamina (β = -0,43; erro-padrão = 0,09; p< 0,01). Conclusão: Horas diárias de trabalho e de descanso parecem ser determinantes do uso de anfetaminae de cocaína/crack entre motoristas profissionais de caminhão.

Abstract: This study aimed to compare the anthropometric measurements and body proportionalities of neonates born before the Zika virus epidemic with those born during this period. We compared 958 neonates born during the pre-Zika epidemic with 264 neonates born during the epidemic period. The newborns had their head circumference, weight, and length classified according to the Fenton & Kim growth chart. We considered disproportionate those individuals that presented microcephaly and adequate weight or length for sex and gestational age, and those whose head circumferences were lower than the ratio ((length / 2) + 9.5) - 2.5cm. We estimated the frequencies of Zika positivity and brain imaging findings among neonates with microcephaly born during the epidemic period, concerning the anthropometric and body proportionality parameters. Low weight and proportionate microcephaly were similar among newborns from both periods. However, the frequencies of newborns with microcephaly with a very low length and disproportionate microcephaly were higher among the neonates of the epidemic period with brain abnormalities and positive for Zika virus. We conclude that, at birth, the disproportion between head circumference and length can be an indicator of the severity of microcephaly caused by congenital Zika.
Os desertos de Breaking Bad: sobre as novas séries televisivas e o mal-estar na cultura
Authors: François Ana Paula Wilke , Froemming Liliane Seide
Published: November 2021

Resumo As séries televisivas têm ocupado cada vez mais espaço na cultura, de forma que seus conteúdos incidem significativamente nas subjetividades. Este estudo aborda as séries dramáticas desta nova era da televisão, iniciada há aproximadamente duas décadas. Atenta-se para certo mal-estar evocado por essas obras, até então incomum na programação televisiva. Toma-se a série Breaking Bad como objeto de análise delimitado e utiliza-se como referencial a pesquisa psicanalítica, que olha para o cinema enquanto linguagem singular. Neste artigo são abordados os resultados obtidos a partir da articulação da série analisada ao conceito freudiano de mal-estar na cultura. Dessas reflexões, destaca-se a dimensão espacial, que é explorada em profusão pela obra audiovisual por meio de recursos formais e que aparece de forma propícia a evocar a questão do mal-estar.

Published: November 2021

ABSTRACT Introduction: Special physical exercise and exceptional physical fitness are an assuredly positive combination for winning. Good exceptional physical fitness is an essential prerequisite for athletes to win competitions. Objective: This study mainly explores the relationship between the functional performance of specialized sports athletes and the performance of specific physical fitness to optimize the functional training and specific physical fitness training system of male tennis players. Methods: The article selects six tennis players as the research objects and conducts active movement monitoring and physical fitness training. Results: Athletes have poor stability in the core area and poor flexion flexibility of both hips and ankles in a symmetrical posture. There is a significant correlation between the functional movement screening test and the tennis-specific physical fitness performance test results. Conclusions: Only by studying body shape and function can we guide the diagnoses and evaluation of an athlete's physical function. We need to formulate reasonable strengthening measures based on the analysis of body shape and function. Only in this way can the athlete's body shape and physical function be effectively enhanced.

ABSTRACT Introduction: Obesity is a chronic disease with excessive accumulation of body fat, exceeding the normal health level and affecting the physiological functioning of the body. Objective: To establish an obesity evaluation standard closely related to health based on sports medicine indexes, and to provide a new theory and method for the formulation of an obesity evaluation standard in China. Methods: Height, weight, skin fold thickness (shoulder, arm) and medical indexes (SBP, DBP, TC, TG, HDL, INS) of 108 female subjects in a city were tested by means of anthropometry, experiment, and mathematical statistics. All the selected medical indicators were evaluated according to clinical medical standards. Results: the body mass index of 108 women was positively correlated with such medical indexes as systolic blood pressure, diastolic blood pressure, triglycerides, high density lipoprotein cholesterol, insulin and so on (P<0.05~0.01). Conclusions: The correlation between medical indexes and BMI is high, and the abnormal rate increases with the increase in the level of obesity. Clinical indicators can be used as an important scientific basis for the establishment of obesity evaluation criteria. Level of evidence II; Therapeutic studies - investigation of treatment results.

Published: November 2021

ABSTRACT Introduction: In recent years, genetic engineering has made outstanding contributions to sports, and it has played a huge role in promoting the development of sports-related fields. Objective: We analyze the tissue source of bone growth and healing by studying the role of bone morphogenetic protein and transforming growth factors in fracture injuries caused by sports. Methods: We established a human fracture model to express the shape and content of bone morphogenetic protein and transforming growth factor during fracture healing. Results: In the fracture healing stage caused by different sports, the expression levels of the two genes are different. Bone morphogenetic protein has a high content in the osteogenesis stage of the membrane, while transforming growth factor is high in the cartilage ossification stage. Conclusion: Gene therapy for fractures caused by physical exercise has certain advantages. Osteoblasts and chondrocytes are involved in the synthesis of transforming growth factors.
