Introduction. Posturograph tests are used to assess the vestibular reflex, which can be helpful for specialists who analyze body balance disorders. Despite many studies on the stability of body posture in pediatric patients, there is still a lack of reliable analysis.Aim. Performing a review of the literature to verify the relationship between balance and body posture as well as stomatognathic system as a part of motor system and the craniofacial complex using a posturograph.Material and Methods. A review of the literature has been carried out for the posturographic examination as a diagnostic tool. The following work is for reference only. A review of the Google Schoolar database and PubMed was made. Keywords used in the search are: (children) and (posturography, posture control, balance, temporomandibular joint). The authors took into account reports published in Polish and English. For the purposes of this review, strict criteria for the inclusion and exclusion of research work have been created.Results. The authors analyzed 335 research papers, of which 5 articles were qualified after the analysis. Studies show that there is a relationship between posturographic examination and postural disorders in children. However, the results are not conclusive and further research is necessary before these results can be considered as fully generalized.Summary. It is necessary to standardize the research using a posturograph. There is a need for further research due to the lack of standardized measurements showing norms for individual age groups.

Index Of Multiple Deprivation

ObjectivesThis study aimed to assess the impact of using different weighting procedures for the German Index of Multiple Deprivation (GIMD) investigating their link to mortality rates.Design and settingIn addition to the original (normative) weighting of the GIMD domains, four alternative weighting approaches were applied: equal weighting, linear regression, maximization algorithm and factor analysis. Correlation analyses to quantify the association between the differently weighted GIMD versions and mortality based on district-level official data from Germany in 2010 were applied (n=412 districts).Outcome measuresTotal mortality (all age groups) and premature mortality (<65 years).ResultsAll correlations of the GIMD versions with both total and premature mortality were highly significant (p<0.001). The comparison of these associations using Williams’s t-test for paired correlations showed significant differences, which proved to be small in respect to absolute values of Spearman’s rho (total mortality: between 0.535 and 0.615; premature mortality: between 0.699 and 0.832).ConclusionsThe association between area deprivation and mortality proved to be stable, regardless of different weighting of the GIMD domains. The theory-based weighting of the GIMD should be maintained, due to the stability of the GIMD scores and the relationship to mortality.

The Relationship

The relationship of parental nurturance to self-esteem for seven distinct adolescent and early-adulthood age groups ( N = 784) was investigated. Analysis showed that even though mothers' and fathers' nurturance together were more strongly related to self-esteem during the junior high school years ( R2 values >50% were obtained in each of the junior high samples) than during the high school and college years ( R2 values < 40% were obtained in each of these samples), parental nurturance still remained a robust predictor of self-esteem during these latter years. These results were discussed within the context of (a) the stability at different ages of the bases upon which one's judgments of self-esteem are made, and (b) parental nurturance as a stabilizing influence during the transitional years of adolescence and early adulthood.

Purpose – The information technology (IT) industry has been continuously expanding. This has resulted in promoting outsourcing of work by clients to vendors. Most of the published research has focussed on when clients should start outsourcing, what to outsource, criteria for vendor selection, etc., however the vendor side of the relationship has been mostly ignored. The purpose of this paper is to delve deep into the vendors’ side and what aspects a vendor needs to consider in order to maintain a good relationship with the clients. Design/methodology/approach – The research design of the paper is to use literature survey to define the components of the client vendor relationship (CVR), identify the parameters impacting the relationship, establish correlation between the independent variables and the dependent variable; subsequently to propose a framework for the CVR. Findings – The findings have been that – communication, technical value addition, knowledge sharing and client vendor adaptability are vital to any outsourcing engagement and if the vendor is able to get good knowledge transfer of the application at hand and the business domain, it can perform better. Vendors, which proactively resolve issues, ensure stable deliveries before time and identify improvements in the software outside the work assigned maintain better relationship. Further a vendor must be adaptable to clients, cultural, time zone differences, should provide a good project manager and be ready to change tools, resources as per client needs. As long as the vendor is able to ensure the above, the stability of the client country and need for information security is not as important to vendors. Research limitations/implications – The study has limitations as it focusses on the vendors’ side and is inclined toward Indian vendors’ perspectives. Future research can include client as well and can be conducted for a different geography. Originality/value – The research work is original and adds value to the IT service outsourcing industry by identifying the parameters which need to be monitored for a sustainable CVR.

In phonology, the terms ‘tenseness’ (tensing) and ‘laxness’ (laxing) are an important pair pertaining to the distinctive features of vowels. A similar dichotomy, ‘tenseness’ – ‘laxness’, can also be observed in the body-gesture (B-G) behaviors. On the basis of this distinction, the author of the article proposes to make a division between two body–gesture cultures, namely: the ‘lax B-G cultures’, and the ‘tense B-G cultures’, respectively. Additionally, the author constructs two working hypotheses. Namely:Hypothesis no. 1 (H1):(H1a): The laxer the B-G system is, the less ritual (and more casual) a given communication act happens to be.(H1b): The relationship “lax body posture + lax gesture” correlates with full spoken, profane (non-ritual) communication potential.Hypothesis no. 2 (H2):(H2a): The tenser the B-G system is, the more ritual a given communication act happens to be.(H2b): The relationship “tense body posture + tense gesture” correlates with full spoken, ritual (nonprofane) communication potential.

Modal Vibration

In view of the complex vibration characteristics of hydrodynamic coupling, dynamic analysis of hydrodynamic coupling is carried out by finite element method (FEM), and modal characteristics of pump and turbine which are the most important parts of it are calculated. Modal vibration analysis data of pump and turbine could be obtained by ANSYS software and the natural frequencies of it within different rotational speed is calculated. The result shows that the natural frequencies of pump and turbine are increasing along with enhance of the rotating speed, and it illustrates that rotating centrifugal force could be reinforced natural frequencies of the structure. According to the relationship between exciting force and rotating speed，the critical speeds of pump and turbine are calculated. And the stability operating condition of hydrodynamic coupling must be avoided in each order critical speed of pump and turbine. The research work provides an effective method to analyze the vibration of hydrodynamic coupling. It is suitable for further dynamic analysis and structure optimum design to reduce the vibration of Hydrodynamic coupling.

AbstractIn this article, we reported a case of spinal muscular atrophy (SMA) type I noted to have tetraventricular hydrocephalus with Blake's pouch cyst at 8 months of age following intrathecal nusinersen therapy. The association of hydrocephalus with SMA is rarely reported in the literature. Development of hydrocephalus after intrathecal nusinersen therapy is also reported in some cases, but a cause–effect relationship is not yet established. The aim of this study was to describe the clinical characteristics of a patient with SMA type I and hydrocephalus, to review similar cases reported in the literature, and to explore the relationship between nusinersen therapy and development of hydrocephalus. The clinical presentation and radiographic findings of the patient are described and a comprehensive review of the literature was conducted. The adverse effect of communicating hydrocephalus related to nusinersen therapy is being reported and the authors suggest carefully monitoring for features of hydrocephalus developing during the course of nusinersen therapy.

This paper presents the findings of the stability, thermal conductivity and viscosity of CNTs (doped with 10 wt% graphene)- TiO2 hybrid nanofluids under various concentrations. While the usage of cutting fluid in machining operation is necessary for removing the heat generated at the cutting zone, the excessive use of it could lead to environmental and health issue to the operators. Therefore, the minimum quantity lubrication (MQL) to replace the conventional flooding was introduced. The MQL method minimises the usage of cutting fluid as a step to achieve a cleaner environment and sustainable machining. However, the low thermal conductivity of the base fluid in the MQL system caused the insufficient removal of heat generated in the cutting zone. Addition of nanoparticles to the base fluid was then introduced to enhance the performance of cutting fluids. The ethylene glycol used as the base fluid, titanium dioxide (TiO2) and carbon nanotubes (CNTs) nanoparticle mixed to produce nanofluids with concentrations of 0.02 to 0.1 wt.% with an interval of 0.02 wt%. The mixing ratio of TiO2: CNTs was 90:10 and ratio of SDBS (surfactant): CNTs was 10:1. The stability of nanofluid checked using observation method and zeta potential analysis. The thermal conductivity and viscosity of suspension were measured at a temperature range between 30˚C to 70˚C (with increment of 10˚C) to determine the relationship between concentration and temperature on nanofluid’s thermal physical properties. Based on the results obtained, zeta potential value for nanofluid range from -50 to -70 mV indicates a good stability of the suspension. Thermal conductivity of nanofluid increases as an increase of temperature and enhancement ratio is within the range of 1.51 to 4.53 compared to the base fluid. Meanwhile, the viscosity of nanofluid shows decrements with an increase of the temperature remarks significant advantage in pumping power. The developed nanofluid in this study found to be stable with enhanced thermal conductivity and decrease in viscosity, which at once make it possible to be use as nanolubricant in machining operation.

В статье представлены материалы о взаимосвязи продолжительности продуктивного использования коров с характеристикой устойчивости к деградации, с возрастом отела и удоем. В исследованной, разнородной по происхождению, группе животных для прогноза продуктивного периода коров, обусловленного устойчивостью к деградации и возрастом первого отела, пригодно уравнение регрессии, аргументами в котором являются индекс устойчивости, возраст первого отела в первой и второй степенях. Коэффициент корреляции межу предсказанными значениями продуктивного периода и его фактическими величинами в I группе составляет 0,502, во II - 0,604. При этом крайние варианты прогнозируются со статистическими ошибками 5 мес при оценке индекса устойчивости по 2 лактациям и 4,1 мес по 3, а средние варианты, соответственно, 1,6 и 1,51 мес. Индекс устойчивости к процессу старения является важной характеристикой биологических особенностей коров, определяющий их продуктивное долголетие. Его оценка по первым 2 и 3 лактациям имеет прямолинейную связь с продуктивным периодом (r=0,4109 и r=0,5270), соответственно. Зависимость продуктивного периода от возраста первого отела криволинейная — с увеличением возраста первого отела сокращается срок продуктивного использования, при возрасте первого отела более 1400 дней срок продуктивного использования колеблется от 1,33 до 1,41 лактации. Коэффициент корреляции между этими характеристиками коров составляет - 0,2164 в I и - 0,2620 во II группах. The article presents materials about the relationship of the duration of productive use of cows with the characteristic of resistance to degradation, with the age of calving and milk yield. In the studied group of animals, which is heterogeneous in origin, the regression equation is suitable for predicting the productive period of cows due to resistance to degradation and the age of the first calving, the arguments of which are the stability index, the age of the first calving in the first and second degrees. The correlation coefficient between the predicted values of the productive period and its actual values in group I is 0.502, in group II - 0.604. At the same time, the extreme variants are predicted with statistical errors of 5 months when evaluating the stability index for 2 lactations and 4.1 months for 3, and the average variants, respectively, are 1.6 and 1.51 months. The index of resistance to the aging process is an important characteristic of the biological characteristics of cows, which determines their productive longevity. Its estimate for the first 2 and 3 lactations has a direct relationship with the productive period (r=0.4109 and r=0.5270), respectively. The dependence of the productive period age at first calving curvilinear with increasing age at first calving reduces the time to productive use, while age at first calving of more than 1400 days, the period of productive use ranges from 1.33 to 1.41 lactation. The correlation coefficient between these characteristics of cows is-0.2164 in I and-0.2620 in II groups.

Проведена статистическая обработка сформированной базы данных показателей неспецифической резистентности MS «Excel» с целью изучения динамики иммунитета по параметрам бактерицидной, лизоцимной и фагоцитарной активности у крупного рогатого скота черно-пестрой породы разных возрастов. Было установлено, что средние значения показателей лизоцимной и бактерицидной активности у телят в 6 мес были ниже (47,89% и 49,09%, соответственно), чем у животных в 3—4 года (53,75% и 52,81%). Выведено уравнение регрессии, описывающее взаимосвязь между средними показателями фагоцитарной активности и возрастом при высокой степени достоверности (R2=0,90). Изменения лизоцимной и бактерицидной активности в зависимости от возраста были недостоверными (R2=0,58 и R2=0,49, соответственно). Установлена высокая корреляция между бактерицидной и лизоцимной активностью. Отмечена динамика изменения неспецифического иммунитета у коров различных возрастных групп. Создание баз данных и постоянный мониторинг основных показателей естественной резистентности в зависимости от различных факторов (породы, возраста, стадий лактации, кормления, способов содержания), которые влияют на данные показатели, необходимо для оценки физиологического состояния организма животных и их устойчивости к болезням. Statistical processing of the generated MS "Excel" on indicators of non-specific resistance database was carried out with the aim of studying the dynamics of the development of immunity in terms of bactericidal, lysozyme and phagocytic activity in black-and-white cattle of different ages. It was found that the average values of indicators of lysozyme and bactericidal activity in calves at 6 months were lower (47.89% and 49.09%, respectively) than in animals at the age of 3—4 years (53.75% and 52.81%). The equation of regression was derived, it describes the relationship between the average indicators of phagocytic activity and the age with a high degree of reliability (R2=0.90). The changes in lysozyme and bactericidal activity depending on age were dubious (R2=0.58 and R2=0.49, respectively). The high correlation between bactericidal and lysozyme activity was established. It was noticed that the cows of different age groups experienced the dynamics of changes in nonspecific immunity. The creation of databases and constant monitoring of the main indicators of natural resistance, depending on various factors (breed, age, stages of lactation, feeding, methods of keeping) that affect these indicators, is necessary for assessing the physiological state of the animals’ body of and their resistance to diseases.
