Congenitally impaired pattern-recognition receptors in pathogenesis of pediatric invasive and recurrent pneumococcal infection
Authors: Tereshchenko S. Yu. , Smolnikova M. V.
Published: July 2019

Here we review currently available data showing that innate immune signs predisposing to recurrent and invasive pneumococcal infections were identified in children. Streptococcus pneumoniae (pneumococcus) belongs to Grampositive bacteria being the major cause of morbidity and mortality in infants, especially in developing countries and in communities with low socioeconomic status. Due to the lack of anti-pneumococcal vaccination, the significant proportion of pneumococcus carriers develop non-invasive (pneumonia, otitis media, sinusitis) and severe invasive (bacteremia/septicemia, meningitis) pneumococcal infection. A great deal of diverse factors related to pneumococcus biological features (virulence factors) as well individualized host-specific immunity are implicated in efficient bacterial penetration across the mucous membranes. The TLR signaling system plays a crucial role in the human nonspecific defense upon the first encounter with the pathogen. Various TLRs comprise the first pattern recognition receptor fami ly ever described which sense ligands derived from the outer bacterial wall. The complement system is the ancient innate immunity component mainly involved in intravascular elimination of bacterial agents. In addition, the complement proteins serve as a bridge between innate and adaptive immunity, ensuring optimal conditions for B- and T-cell maturation and differentiation. Because pneumococcus secretes the IgA protease, a local protective effects related to IgA antibodies might not be so prominent. Therefore, B-cell immunodeficiency and impaired complement system hold a lead place among congenital causes resulting in severe and recurrent pneumococcal infections in children. Thus, based on available data, we concluded that impaired B-cell function, the complement components deficiency as well as receptor-recognition receptors (TLR-2, -9, -4, MYD88 adapter protein, TLR cascade enzymes: IRAK4, NEMO, NOD-like receptors: NOD2, NLRP3; C-type lectins: MBL, Dextin-2, and, possibly, ficoline) play the most important role among congenital immunodeficiencies predisposing to invasive and recurrent pneumococcal infections play the most important role among congenital immunodeficiencies predisposing to invasive and recurrent pneumococcal infections, and should be used as a rationale for immunological surveillance and organizing immunogenetics screening in these patients.

Published: July 2019

Hepatitis E is an acute viral infectious disease transmitted by fecal-oral route mainly through fecally contaminated drinking water, with cyclic outbreaks and frequent development of acute hepatic encephalopathy in pregnant women. Hepatitis E epidemic outbreaks occur in Central Asia, Africa and Latin America, whereasChina,India,Turkmenistan,Kazakhstan,Tajikistan,Uzbekistan,Kyrgyzstan,Bolivia,Mexico, andTaiwanrepresent endemic geographic regions. Hepatitis E in the structure of acute viral hepatitis morbidity during outbreaks ranges from 64.7% to 80%, whereas sporadic morbidity may be up to 10 to 18.8%. In contrast, percentage of hepatitis E in acute viral hepatitis varies from 0.5% to 12.6% in European countries and some territories of theRussian Federation. The latent active virus circulation was confirmed in various regions of theRussian Federation. All introduced cases were related to recent traveling to the regions with high incidence of hepatitis E, which course clinically did not differ from standard hepatitis E infection, but no cases of infection were recorded after exposure. Lack of contact transmission in this case was associated with low virus survival in environment. Patients with any clinical form including anicteric serve as a source of infection. An increased risk of hepatitis E infection is typical for livestock workers dealing with pigs, employe es of meat processing plants engaged in primary meat carcass processing and working at slaughterhouse. According to the World Health Organization, 20 million cases of hepatitis E virus infection are recorded annually, among which 3 million cases account for acute hepatitis E and related 70 000 lethal outcomes. Chronic liver disorders comprising up to 70% followed by death of pregnant women (40%) as well as acute liver and kidney failure reaching as low as 4% result in lethal outcome in hepatitis E patients. Creating a mathematical model for development of hepatitis E infection could allow to predict changes in its morbidity rate at controlled area. Here, for the first time we propose a mathematical model for developing hepatitis E in human population based on disease course, which may potentially predict an incidence rate for the most dangerous icteric hepatitis E as well as assess amount of individuals susceptible to it at morbidity rise in the geographic region.
Point-Based Value Iteration for Finite-Horizon POMDPs
Authors: Walraven Erwin , Spaan Matthijs T. J.
Published: July 2019

Partially Observable Markov Decision Processes (POMDPs) are a popular formalism for sequential decision making in partially observable environments. Since solving POMDPs to optimality is a difficult task, point-based value iteration methods are widely used. These methods compute an approximate POMDP solution, and in some cases they even provide guarantees on the solution quality, but these algorithms have been designed for problems with an infinite planning horizon. In this paper we discuss why state-of-the-art point-based algorithms cannot be easily applied to finite-horizon problems that do not include discounting. Subsequently, we present a general point-based value iteration algorithm for finite-horizon problems which provides solutions with guarantees on solution quality. Furthermore, we introduce two heuristics to reduce the number of belief points considered during execution, which lowers the computational requirements. In experiments we demonstrate that the algorithm is an effective method for solving finite-horizon POMDPs.
Northam River Bridge, Southampton, UK: a life-extension maintenance project
Authors: Simpkins John , Cole Graham
Published: July 2019

The Northam River Bridge in Southampton, UK, carries the A3024 principal road across the River Itchen. The 1954 structure was a pioneer of early concrete post-tensioning techniques, with longitudinal prestressed beams held together both transversely and longitudinally with transverse post-tensioning. Works started in 2014 to address extensive water seepage that was potentially corroding post-tensioning elements. The need to avoid traffic disruption was a significant constraint in delivering the scheme. A post-tensioned special inspection to vulnerable details was undertaken when the main works contract started and a contraflow system was introduced. This revealed issues with the transverse tensioning that implied a need for reassessment. The outcome was that the majority of the structural elements were suitable for 40 t assessment live loading. However, there was a further requirement for measures to prevent any accidental wheel loading to the edge beams.
Stress wave velocity in soils: Apparent grain-size effect and optimum input frequencies
Authors: Dutta T. T. , Otsubo M. , Kuwano R. , O'Sullivan C.
Published: July 2019

There is a lack of consensus in the literature on the influence of the median particle size on stress wave velocity in cohesionless soils. For assemblies of spherical particles with Hertzian contacts, the stress wave velocities should not depend on particle size. However, a link between particle size and stress wave velocity has been reported in laboratory experiments. In this study, to identify the reasons for the discrepancies, wave velocity measurements were performed using planar piezoelectric transducers on four different sizes of alkaline glass beads and natural silica sands. The experimental results indicate that shear and compression wave velocities are independent of the median particle size. In accordance with the dispersion theory, both the experiments and discrete-element simulations demonstrate that the maximum frequency that can propagate through a granular assembly (i.e. the low-pass frequency) reduces with increasing median particle size. The relationship between the low-pass frequency and the input signal frequency determines the quality of the received signal and hence the accuracy of the interpreted stress wave velocity data. To accurately estimate shear wave velocities, the selected input frequencies should match those frequencies which exhibit the largest gain factors and the input frequencies should not exceed more than half of the low-pass frequency. To determine the compression wave velocity, it is suggested that the start-to-start method be adopted and an input frequency which is slightly lower than the low-pass frequency be chosen.
Evaluation of virtual fixed points in the response spectrum analysis of a pile-supported wharf
Authors: Yun J.-W. , Han J.-T. , Kim S.-R.
Published: July 2019

Response spectrum analysis is widely employed in the seismic design of pile-supported wharves, as it can easily determine the maximum response of a structure. The analysis typically uses virtual fixed points to model the structure, without modelling the ground, as the structure is assumed to be a frame. Virtual fixed points can adequately simulate pile responses under horizontal static loads; however, pile responses under seismic loads have not been well studied. Therefore, the dynamic centrifuge tests evaluate the applicability of response spectrum analysis, using virtual fixed points, to the seismic design of a pile-supported wharf. Comparison of results from scale models (3 × 3 groups of piles from sections of Pohang New Port, Korea) with those from the analysis showed that the response spectrum analysis using virtual fixed points does not adequately simulate the natural period or pile bending moment of a pile-supported wharf system.
La escucha como apertura existencial que posibilita la comprensión del otro
Authors: Joaqui Robles Darwin , Ortiz Granja Dorys Noemy
Published: July 2019

The article approaches the subject of listening as a central axis of an existential openness that promotes the understanding of the other. It is an relevant issue since that widely reflected about the language and its possibilities; however, the listening has been little addressed so it remains in a discreet silence that is important to clear. The main objective of this proposal is to highlight the value that listening has to reach the understanding of the other and the construction of dialogical relations between humans’ beings. To do this, a descriptive journey is made about language and its characteristics, emphasizing its two components: speech and listening as an interrelated process to understand its role in the construction of linking narratives among human beings. An essential part of this process is the time for which some reflections on the subject are made to conclude with the question of listening that provides the possibility of an existential openness that facilitates the understanding of the other. The description is made in a descriptive, reflective and hermeneutic way, with the support of the ideas of the main authors of the Philosophy and of other disciplines. The ideas and their arguments have been organized into three essential themes: language, time and listening, to conclude by highlighting the main arguments of each of the aspects considered in the reflection.
La (re)invención del pasado como gesto de (des)composición de la pedagogía
Authors: Ramallo Francisco
Published: July 2019

The processes of recording the past in education commonly forget their pedagogic power, thus paradoxically contributing to nostalgic, fossilized accounts. However, the matrix junction of narrative research and critical pedagogies fosters the composition of stories that invigorate and inhabit a more sensitive past —one which is more polite towards life. We hereby aim at disturbing the classical perspectives of History of Education with the partial, fluent and provisional intention of intervening in coloniality and the normalization of the legitimacy of “the” educational narrative. Specifically the objective is a (re) of a past —the past of Argentinian high schools— from a methodology of narrative research —which weighs both the data of the field and the reflections on what is done with them—; by the abolishment of its forms and the inversion of its enunciation as a means to fostering gestures leading to what we call a (de) composition of pedagogy. Preoccupation that becomes paramount to stop interpreting it as a social science that studies education, because in this way it is usually relegated to its systemic, technical and disciplinary use. The stories collected from the Argentinian high schools, dislocate it from its classical notion to try to understand it as a narrative in which human relations of education are verbalized in an extended and vital sense. In short, they activate a discursive power as a condition to restore other ways of knowing, being and knowing.
Diseño de certificación lingüística comunicativa: ¿cómo evaluar la expresión e interacción escritas y orales?
Authors: Baralo Marta
Published: July 2019

La posibilidad de medir y de evaluar las actividades de expresión y de interacción en una lengua, sea por el canal oral o el escrito, es un desafío para los especialistas en lingüística aplicada pues se trata de una apreciación subjetiva, que depende en gran parte del evaluador, de sus creencias y actitudes. Para conseguir que la prueba de evaluación sea válida, fiable y auténtica es necesario que su diseño esté sujeto a un conjunto de parámetros de calidad establecidos por las agencias e instituciones especializadas y que su aplicación cuente con un conjunto de herramientas de evaluación suficientemente probadas y un conjunto de evaluadores preparados que aseguren el acuerdo en la valoración del desempeño lingüístico comunicativo de los candidatos. Se presenta aquí la experiencia investigadora en el marco del diseño e implantación del Diploma LETRA (Lengua Española para Trabajadores inmigrantes) en la Comunidad de Madrid.
Los diccionarios en el mundo ELE: ayer, hoy y mañana (una reflexión desde la propia experiencia)
Authors: Maldonado González Concepción
Published: July 2019

Dos preguntas clave deben responderse para poder abordar con éxito un proyecto lexicográfico didáctico pensado para la enseñanza del español como segunda lengua: ¿Deben los estudiantes de ELE consultar un diccionario monolingüe o uno bilingüe? ¿Por qué, si para el usuario el diccionario es siempre un instrumento al que se le exige una utilidad práctica inmediata, los lexicógrafos y profesores de ELE nos empeñamos en convertirlo en un medio con el que hacer ejercicios con objetivos de aprendizaje a largo plazo? De la respuesta que demos a ambas preguntas, y de la adecuación del trabajo lexicográfico a los tiempos actuales (es decir, a los tiempos de las obras de consulta en digital), dependerán el éxito o el fracaso de un diccionario ELE.

Magnetic spring effect on the force characteristics of the electromechanical magnetic liquid damper
Authors: Nesterov S.A. , Morozov N.A. , Kazakov Yu.B.
Published: July 2019

The effect of a magnetic spring is observed in electromechanical devices with limited pole sizes. Simultane-ous changing of the system magnetic conductivity after a relative displacement of the poles causes mag-netic tension forces. These forces in electromechanical magnetic fluid dampers have their own specific characteristics which have not been studied before. All this requires studying the effect of a magnetic spring on the damper power characteristics, estimating the effect of the properties of a magnetorheological suspension on the magnetic spring strength, nature of its change and combination of the action of magnetic forces and viscosity resistance to the piston movement. To do that, it is important to analyze the effect of a magnetic spring in statics, at a slow movement of the piston and its dynamic oscillations. The studies were based on the theory of natural experiment and methods of processing experimental results. We have obtained and analyzed dependences of the resistance force of the electromechanical magnetic fluid damper for different vibration frequencies and magnetic inductions. The effect of magnetic spring forces on the damper power characteristic has been investigated. It has been found how the damper resistance force is affected by the magnetic and hydrodynamic components. The use of a damper with alternating elements with high and low magnetic conductivities makes it possible to change the strength characteristic of electromechanical magnetic fluid dampers. The proportion of the force controlled by the magnetic field reaches 75 % of the total effort. The use of the magnetic spring effect allows increasing the damping efficiency at small amplitudes and vibration frequencies. Increasing the magnetic properties of a magnetorheological suspension enhances the effect of a magnetic spring if the piston is non-magnetic, and weakens it if it is a magnetic one. When the magnetic induction rises, the effect of the magnetic spring increases. By changing the initial piston position, it is possible to obtain an asymmetrical power characteristic, for example, without using valves and spools, to increase the rebound force and to reduce the compressive force. If there are no moving parts, the damper reliability increases.
Development of a control algorithm for the three-phase inverter of the two-phase electric drive for reducing the number of switching elements
Authors: Meshcheryakov V.N. , Belousov A.S.
Published: July 2019

High overload capacity and ability to control speed in a wide range are important requirements for modern electric drives. Introduction of a low-power adjustable two-phase electric drive with these properties into me-chanical devices is limited by the frequency converter function to convert a three-phase network into a two-phase one when the unit power of such mechanisms increases. Previous studies have shown that it is possible to use a standard frequency converter with a three-phase bridge voltage inverter applying a new control algorithm based on space-vector PWM. When PWM is used, the switching frequency of the key inverter elements remains quite high, strictly specified, non-amenable to reduction without degrading the harmonic composition. The goal of this work is to develop an algorithm for two-phase electric drive control that would reduce the number of switching operations of the switch elements of a three-phase inverter with-out increasing the deviations of the instantaneous values of the phase currents from the reference sine curve. The study employed provisions of the theory of automatic control, the theory of electric drive and methods of mathematical modeling. The simulation object was the control system of a two-phase motor; the elements of the Matlab Simulink software package were used. An algorithm has been proposed for operating a three-phase inverter of a two-phase electric drive system. The difference of the algorithm from the well-known control system of a standard bridge inverter with space vector PWM consists in using phase current control relays and dividing the period of sinusoidal phase currents into four sections ensuring a decrease in the number of switching operations of the inverter switch elements when the maximum instantaneous deviations of current values from a sinusoidal reference are equal, the starting torque of the motor is stabilized and the speed control is smooth. The results show that with an equal maximum deviation of the instantaneous current values from a given sinusoidal value, the number of switching operations of the inverter switch elements in the proposed system is smaller than in the known analogues. The electric drive system ensures the start of a two-phase motor with stabilization of the starting torque under increased load. The considered system of variable frequency control with current control relays can be used for two-phase electric drives of mechanical devices and household electric appliances and is promising as a substitute for less cost-effective single-phase and capacitor motors.

The three-dimensional (3D) printing manufacturing process begins with the creation of a 3D model—using computer aided design (CAD) software—of the part to be printed. Using a type of 3D printing known as fused deposition modeling (FDM®), the 3D printer extrudes molten plastic to scan lines to create individual layers (i.e., the infill): one on top of the other. (Note that "scan" in this context refers to the movement of the extruder head, along an x,y coordinate path, while depositing molten plastic.) This process is repeated until the overall geometry, specified by the 3D model, is built. This process is attractive for producing proof of concept or prototype parts in various fields including automotive, aerospace, and medical. However, FDM subjects the material to rapid heating and cooling; therefore, some degree of undesirable warpage of the part occurs post fabrication. The primary objective of this study was to determine the effect of 4 process parameters (i.e., infill shape, infill density, number of perimeters created per layer, and layer height) on the total dimensional error of a representative 3D-printed part. This part (the "simple part"), used in Trials 1 through 3 of this study, was a square acrylonitrile butadiene styrene (ABS) plate having a nominal measurement of 50 mm × 50 mm × 5 mm thick. A residual error (the difference between the measured post-printing dimension and the theoretical CAD file dimension) was calculated along each given direction and for each test print. Finally, a root mean square (RMS) error (i.e., the square root of the average of the squared residual errors along the length, width, and thickness directions) was calculated for each printed part. Three repeat test prints were carried out for each parameter. The number of perimeters played a key role in the dimensional stability of the part. As the number of perimeters increased up to 5, the RMS error decreased. Beyond 5 perimeters, however, the RMS error increased due to excessive warpage/curvature at the corners of the part. Ultimately, when examined individually, a grid infill shape at 100% density, a 0.4 mm layer height, and 5 perimeters each produced the lowest warpage. In combination, these same 4 parameters also produced the lowest RMS error (based on dimensional analysis of 3 test prints) when used to print a more complicated part (the "stacked part") in Trial 4.

Testicular torsion is a serious scrotal emergency having a negative impact on fertility and in its most severe presentation, there is potential loss of the testicle if not diagnosed early. The condition needs to be diagnosed promptly with immediate surgical intervention. Intermittent testicular torsion (ITT) is a forerunner or a red flag for an impending frank testicular torsion. ITT is characterized by sudden onset of testicular pain which may resolve spontaneously before further investigation and treatment. Testicular torsion in adults is usually intravaginal in location and can be diagnosed clinically if the patient presents early with typical clinical signs. A case of ITT who presented with frank unilateral testicular torsion diagnosed clinically and surgically treated with salvage of the affected testes is presented to highlight the importance of history of ITT and typical clinical features. The anatomical aspects and pathophysiology of testicular torsion including the aftermath is discussed. ITT is a forerunner to frank testicular torsion. If offered prophylactic orchidopexy then a frank episode of testicular torsion with all its sequelae can be averted.

Background: Surgical diabetes is syndrome of hyperglycemia and disturbance of carbohydrate, fat and protein metabolism associated with absolute or relative deficiency of insulin secretions. Diabetes mellitus and hypertension considered as a major medical and public health issues worldwide, and both are important risk factors for both macrovascular and microvascular diseases like coronary artery disease, heart failure and cerebrovascular diseases.Methods: This cross-sectional study was conducted among 175 patients coming to Govt. medical college and SSG hospital, Vadodara from 2014 to 2015 having diabetes mellitus were studied and evaluated for hypertension  and its various risk factor like age, obesity.Results: one hundred and twenty-nine (127) out of 175 subjects had hypertension, thus giving a prevalence rate of 73.7% of which 64 males (49.6%) were hypertensive compared with 65 (50.3%) females. Mean age of patients having hypertension with Diabetes Mellitus (case) is 59.87 compare to DM without hypertension (control) was 56.21. Mean BMI in diabetes cases with hypertension was 30.93 while without hypertension was 23.47 suggest obese are more prone to develop hypertension. Waist hip ratio DM with hypertension was 0.96 while was 0.81 in DM without hypertension.Conclusion: Hypertension and its associated risk factor like obesity, dyslipidemia are important risk factor for development of complication in diabetes patients so early detection and intervention measures should be undertaken for aggressive control of  blood pressure control , obesity and it will  likely to offer the greatest promise for reducing the incidence of complications and its associated mortality.

Background: Nigeria continues to have one of the highest rates of maternal mortality in the world at 814 deaths per 100,000 live births despite several efforts. Various factors can influence appropriate utilization of services during pregnancy, childbirth and postpartum. This study examined the perceived factors that influence the utilization of maternal and child-health services among mothers in Enugu, South-East Nigeria.Methods: A descriptive survey design was adopted for the study. The study population of 323 pregnant women was determined using the Power Analysis formula. The instrument used for data collection was a self-developed questionnaire. Demographic information of the women was also obtained for the study. The analysis was done with the software statistical package for Social Sciences (SPSS) Version 16.0. Study period was from April 2016 to August 2016.Results: There was high antenatal clinic attendance (93.1%) and utilization of postnatal care services (93.1%). Also, the major factors that influenced the utilization of maternal and child health services were professionally defined needs, accessibility of health care services and economic status.Conclusions: There was high utilization of maternal and child health care services which was influenced by some factors. There is a need for nurses and other health workers to be actively engaged in educating mothers during antenatal visits. Sustainable financial subsidies and community-based initiatives should be developed to encourage early antenatal clinic visits and to provide the necessary information on the importance of facility-based antenatal and postnatal care.

Introdução: Um dos defeitos de esmalte que vem desafiando os odontopediatras é a Hipomineralização Molar-Incisivo (HMI), uma alteração de origem sistêmica caracterizada pela diminuição da mineralização de um até quatro primeiro molar permanente e que surge frequentemente associada aos incisivos permanentes, os quais podem estar, igualmente, afetados. Objetivo: O propósito deste trabalho é realizar uma revisão da literatura sobre as possibilidades de tratamento em molares afetados pela HMI. Método: Através de uma revisão de literatura, foi feito buscas nas bases de dados Biblioteca Virtual em Saúde, Scientific Electronic Library Online (Scielo) e Google Acadêmico. Os termos utilizados foram hipomineralização, molar, incisivo, anomalias. Resultados: Os tratamentos variam desde aplicação tópica de flúor à restaurações e exodontias. A decisão do tratamento depende do grau de acometimento do dente com HMI. A utilização de vernizes fluoretados são essenciais no início de todo tratamento com a finalidade de diminuir a sensibilidade presente nesses casos. Conclusão: Por meio desta, concluiu-se que, o estabelecimento de um correto plano de tratamento é fundamental para proservação do elemento dental, sendo necessário o conhecimento dessa alteração para o profissional fazer a melhor escolha.
