Effects of Rubber Particles on Rheological and Mechanical Properties of Concrete Containing CaCO3 Nanoparticles
Authors: Wang Li , Zhao Ben Dong
Published: July 2018

Lots of waste rubber is being produced in the world and the utilization of it not only mitigate environmental impacts caused by waste rubber disposal but also enhance sustainable development. As a result, rubberized concrete, by incorporation of waste rubber into concrete, should be considered as one of the effective strategies to take advantage of waste rubber. However, problems such as low strengths, weak adhesion between rubber particles and cement pastes, and undesirable pore structures associated with rubberized concrete should be pay more attention to. In this study, the effect of replacement fine aggregate with rubber particles on rheological and mechanical properties of concrete containing CaCO3 nanoparticles was examined through slump, compressive and flexural strength tests. Rubber particles were employed to replace the fine aggregate equally by volume while CaCO3 nanoparticles were used as an equal part of binder by weight. Different sizes and volume contents of rubber particles were evaluated as well as different weight contents of CaCO3 nanoparticles. In addition, corresponding tests were also performed to evaluate the effect of CaCO3 nanoparticles in comparison to concrete specimens without CaCO3 nanoparticles. The results showed that replacement fine aggregates with rubber particles had some influence on the mechanical properties of rubberized concrete, resulting in undesirable findings in terms of compressive and flexural strengths. However, the incorporation of CaCO3 nanoparticles improved mechanical properties of rubberized concrete. Regarding slump test, the rubberized concrete without CaCO3 nanoparticles showed better performance. Considering rheological and mechanical properties, rubberized concrete with 1% CaCO3 nanoparticles presented acceptable results.

Published: July 2018

In recent years there has been an increasing tendency to use wastes in manufacturing construction material. Some of the studies were dedicated to recycling hazardous waste in a manner that is safe and protective of human health and the environment. The aim of this work is to study the possibility of using clinical waste as the aggregates for manufacturing construction materials. For that purpose, firstly a technology of initial sterilization with combustion of clinical waste was considered. Secondly as along as the clinical waste became sterile and environmentally safe, non-hazardous fractionated products of clinical waste combustion were proposed as aggregate for concretes. This study reports the results of the experiment when different concrete compositions with such aggregate were obtained, investigated and tested using samples (100 mm cubes). Physic-chemical properties of the material were described; its environmental impact was assessed. Thirdly, the potential of the big city in clinical waste generation and subsequent use of fractionated products of clinical waste combustion in construction materials manufacturing was evaluated. As a result of the use of ArcGIS ESRI geoinformation system, a visual representation of the information has been provided. The results of this study show the possibility of using non-hazardous clinical wastes combustion products in manufacturing construction materials and also in road construction.

Authors: Yao Wen Juan , Fan Lei , Liu Guang Yan
Published: July 2018

The hydration products, microstructure and development principle of intensity of cement-glass powder cementitious materials acted in alkali and activation effect of chemical activation on waste glass powder were investigated. The principle of intensity and effect of curing time was analyzed by changing alkali type, content of alkali, incorporation of glass powder, incorporation method of activators and other factor. The result shows that: sodium carbonate and sodium silicate can single stimulate activity of glass powder under a certain condition, the activated effect of combined admixture is superior to the effect on single-doped activator, under the action of an excitation agent, surface hydrolysis of glass powder takes place on the glass body first and the hydration products occurs, The pozzolanic reactivity of glass powder increases gradually and generated a larger amount of hydration products，which has lapped and interlocked growth between each other，and form the compact hardened matrix. In addiation, the shorting of curing time is used by activator, the result may be lead to initial curing and against in engineering construction.
Effect of Osmotic Pressure by Salt Concentration on Corrosion Resistance of Anti-Corrosive Paint
Authors: Moon Kyung Man , Lee Myeong Hoon , Baek Tae Sil
Published: July 2018

Recently, many types of constructional steels have been often exposed to severely corrosive environments due to acid rain with increasing environmental contamination. To control corrosion problems, a painting protection method has been widely applied to numerous constructional steels on land as well as offshore. Therefore, development of anti-corrosive paint with good quality of corrosion resistance is very important from an economical perspective. In this study, four types of anti-corrosive paint were coated to test specimens, and then, were immersed in various salt solutions (0.1, 3 and 9% NaCl solution) for 11 days. Corrosion resistance of these samples by effect of osmotic pressure with various salt concentration was investigated with electrochemical methods such as measurement of corrosion potential, impedance and corrosion current density. Corrosion current density of these samples submerged in 0.1% NaCl solution exhibited highest value than those immersed in 3% and 9% NaCl solutions because water, dissolved oxygen and chloride ion etc. is easily to invade towards inner side of coating film due to increasing osmotic pressure compared to 3% and 9% NaCl solutions. However, corrosion current densities of all samples in the case of submerged in 9% NaCl solution exhibited higher values compared to 3% NaCl solution.Thus, a large amount of chloride ion dissolved in 9% NaCl solution plays a more critical role in corrosion behavior of coated steel rather than osmotic pressure. Consequently, the corrosion mechanism between coated steel and bare steel plates is different from each other because of presence of osmotic pressure between salt solution and coating film of coated steel plate. As a result, corrosion resistance of tcoated steel plate may be depend on the osmotic pressure as well as salt concentration

Authors: Protsenko Alexander E. , Malisheva Daria P. , Petrov Victor V.
Published: July 2018

The article presents the data of an experimental study on how heat treatment influences the physical and mechanical properties of cured samples of sandwich structures. The sandwich structures were made using VaRTM method. Heat treatment at 80 °С and 60 °С leads to increase in the tensile strength. Three-point bend tests were conducted. The results characterize the relationship between the durability and the temperature and exposure time of the sandwich structures. The results correlate with the data of structural studies of fracture cross-sections and research on the extent of swelling of the cured binder. The SEM micrographs of the microstrustructures of fiberglass reinforced plastic samples show that during heat treatment there is a structural refinement of the polymer matrix. As a result of heat treatment at 80 °С for 4 hours, the extent of swelling decreased by 14%. The heat treatment of sandwich structures at a temperature of 80 °С for 4 hours is optimal and leads to increase in the tensile strength by 30.7%.

Authors: Park Hyun Bum
Published: July 2018

This study aims to investigate numerically the damage area of a sandwich composite structure. In this work, the optimal sandwich core modeling method was proposed. This study applied two modeling methods to compare their analysis results for the structural analysis of the sandwich composite structure. Firstly, the modeling of sandwich core structure was performed with laminate modeling method. Secondly, the modeling of core structure was performed with core solid modeling method. The laminate modeling method was compared with the core solid modeling method. For the modeling, a carbon/epoxy composite structure was applied to the face sheet. And a nomex honeycomb core was applied to the core. Finally, comparing the result of modeling as actual shape with the one of virtually applying the thickness and modeling, it was examined that the former had three times more stress than the latter.

Published: July 2018

Forest ecosystems have been studied for terrestrial components and other faunal assemblages while information on aquatic plants on this regard is scarce. Thus, present preliminary study was designed to study the abundance, distribution and factors influencing on aquatic plant distribution in forested stream selecting “Gong Gawwa Ela” locate in the Kottawa forest reserve. Six sites were selected along a stretch of the stream (~1 km). Those sites were visited once in every month for a period of three months. For each site, plant distribution was observed in a transect across the stream perpendicular to the river bank. Water quality, water flow velocity and sediment composition at each site were also monitored. Eleven aquatic plant species were found along the stream while the most common species were Lagenandra thwaitesii, Aponogeton rigidifolius and Adiantum sp. A significant difference in plant diversity among study sites was noticed where the highest plant diversity was found in the most downstream site. Irrespective to the species; distribution of above three species exhibited a significant positive correlation to the sediment composition. Further, diversity of aquatic plant was significantly correlated to the abundance of L. thawaitsii. There was no significant difference in dissolved oxygen, pH, temperature and biological oxygen demand among study sites. Present study revealed that sediment composition and the abundance of L. thawaitsii are two factors that decide the architecture of the aquatic plant communities along this stream.
Active Scapular Retraction and Acromiohumeral Distance at Various Degrees of Shoulder Abduction
Authors: Harput Gulcan , Guney-Deniz Hande , Düzgün İrem , Toprak Uğur , Michener Lori A. , Powers Christopher M.
Published: July 2018

Context: 

Performing shoulder-abduction exercises with scapular retraction has been theorized to reduce the potential for shoulder impingement. However, objective data to support this premise are lacking.

Objective: 

To evaluate the influence of active scapular retraction on acromiohumeral distance (AHD) at 4 shoulder-abduction angles using real-time ultrasound.

Design: 

Cross-sectional study.

Setting: 

University laboratory.

Patients or Other Participants: 

Twenty asymptomatic individuals (10 men, 10 women; age = 22.9 ± 2.8 years, height = 169.3 ± 9.5 cm, mass = 65.5 ± 12.9 kg) were recruited.

Main Outcome Measure(s): 

Real-time ultrasound images of AHD were obtained during nonretracted and retracted scapular conditions at 0°, 45°, 60°, and 90° of shoulder abduction. A 2-factor analysis of variance with repeated measures was used to evaluate the influence of shoulder retraction on AHD across shoulder-abduction angles.

Results: 

A scapular-retraction condition × shoulder-abduction–angle interaction for AHD was found (F3,57 = 4.56, P = .006). The AHD was smaller at 0° (10.5 versus 11.2 mm, respectively; t19 = 2.22, P = .04) but larger at 90° (9.4 versus 8.7 mm, respectively; t19 = −2.30, P = .04) of shoulder abduction during the retracted than the nonretracted condition. No differences in AHD were observed between conditions at 45° (t19 = 1.45, P = .16) and 60° (t19 = 1.17, P = .86) of abduction.

Conclusions: 

The observed differences in AHD at 0° and 90° of shoulder abduction were small and did not exceed the established minimal detectable change for either angle. Our findings suggest that active scapular retraction during shoulder abduction has a minimal influence on AHD at 0° and 90° in healthy individuals. Further investigations are needed to determine whether scapular retraction influences AHD in individuals with subacromial impingement.
Heterogeneous hydraulic properties of an insular aquifer clarified by a tidal response method with simple decomposition techniques
Authors: Shirahata Katsushi , Yoshimoto Shuhei , Tsuchihara Takeo , Ishida Satoshi
Published: July 2018

Two simple frequency decomposition techniques were used as part of a tidal response method to derive the hydraulic diffusivities of a freshwater-lens aquifer. Digital high-pass filtering can separate the tidal components of diurnal and shorter periods from longer-period components. Discrete Fourier transform can be used to isolate a specific tidal component. These techniques are easy to practice using the built-in functions of spreadsheet software. The applied techniques were each optimized for the frequencies of known major tidal components. Isolation of the specific tidal signals helps to reduce the errors of a basic tidal response method that uses in its calculations the amplitude attenuation and phase lag of a simple sinusoidal wave of groundwater fluctuations. Another advantage of the present tidal method is the utilization of two groundwater time series collected from near-shore and relatively inland sites affected by the same ocean tide. The method does not use surface-water observation, thus avoiding errors derived from generally possible surface-water/groundwater boundary effects.The tidal response method with simple decomposition techniques was used to investigate the aquifer properties of an uplifted limestone island located in a subtropical region of Japan. A freshwater lens is the principal water resource for this island and its sustainable development is desired. Significant hydraulic layering has not been reported in the limestone aquifer. Pairs of groundwater-level time-series data collected by simultaneous observations at near-shore and inland sites were analysed by the tidal response method. The results demonstrated heterogeneous aquifer diffusivity on the island, typically with larger values in the southeastern coastal part than in the northwestern coastal part, which is consistent with the planar distribution of the entire freshwater lens and the position of its maximum thickness that are slightly biased toward the northwestern side.

Published: July 2018

La educación es uno de los elementos más importantes para el desarrollo de la sociedad. En México y Centroamérica, de donde proviene la gran mayoría de los inmigrantes no autorizados en EEUU, la igualdad de oportunidades en el acceso al sistema educativo y su permanencia sigue siendo una asignatura pendiente. Por ello, el logro educativo, al igual que la mejora material, son aspectos muy importantes del “sueño americano” de la población que desea alcanzar ese país, y particularmente de las mujeres migrantes de nuestro estudio.En el siguiente artículo presentamos los resultados de una investigación desarrollada en la frontera norte de México con EEUU, en la cual analizamos las expectativas educativas de las mujeres migrantes en tránsito en su proyecto migratorio y cómo la educación es una variable importante en la preparación de su viaje, y en la minimización de los riesgos. A través de entrevistas en profundidad se realiza un análisis cualitativo de las motivaciones que llevan a estas mujeres a iniciar su viaje y los recursos con los que cuentan para hacer frente a los riesgos, estando la educación presente en ambos casos.Entre los resultados obtenidos, podemos establecer que la educación formal recibida en sus lugares de origen condiciona el proyecto migratorio de mujeres migrantes viajando a EEUU en condición indocumentada, su alcance, estrategia de viaje, así como las respuestas ante los peligros. Y de la misma manera, el logro educativo, de sí mismas o de sus dependientes, es parte de su proyecto migratorio. Donde, por otra parte, la noción del retorno en ellas no les permite, en algunos casos, ver cumplidas sus expectativas del “sueño americano”.

En el dilema de Jano. Un comentario a la sentencia 1221/2014 del Tribunal Supremo Popular de Cuba
Authors: Limonta-Montero Reynier
Published: June 2018

El problema de la interpretación judicial y los alcances de los dictados de la ley ha sido y será uno de los más difíciles asuntos teóricos en la llamada ciencia del derecho. Sin embargo, dada la obligatoriedad de la interpretación judicial y su carácter de norma jurídica concreta, resulta un aspecto imprescindible para juristas, estudiosos y operadores jurídicos en general. El presente trabajo delinea estos asuntos y tiene como centro la decisión del máximo foro judicial cubano en un recurso presentado en materia tributaria. Por la alta investidura de esta esfera judicial, es lógico que sus decisiones implican a todo el sistema de tribunales y conforman una pauta interpretativa para casos revestidos de características similares. Por otro lado, la ratio decidendi del caso analizado tiene vínculos profundamente interdisciplinarios y polisémicos, lo que crea un nexo, descrito en este trabajo, entre el mandato constitucional, lo ordenado por las normas y la práctica sobre estas mismas materias. Se trata del análisis de una materia emergentemente vigorosa en medio de la llamada actualización del modelo económico cubano.
Freedom, Power, and the Global Economic Order
Authors: Sutch Peter
Published: July 2018

This article develops arguments found in chapter six of Freedom Is Power: Liberty through Political Representation, concerning how Hamilton's account of freedom might inform our thinking about global justice. Hamilton's work grapples with the problem of domination and freedom in a postapartheid and postcolonial world order. While we find important statements of this theme in some of the canonical texts of the tradition, Hamilton's treatment of the theme hints at a further reaching, more demanding engagement with “real modern freedom”—freedom in the vast shadow of economic, political, and cultural domination. This contribution seeks to place his work within debates in normative international political theory and to compare his position (and its implications) with those arguing for normative and institutional change in world politics including questions of distributive justice and global economic governance.

Published: July 2018

Este artigo tem por objetivo investigar a vivencia e participação feminina em cargos eletivos no município de Cruzeiro do Oeste, localizado no noroeste do Estado do Paraná, enfocando os tempos atuais. Este município foi fundado em 1952, e atualmente com cerca de 21.000 habitantes (sendo 16.375 eleitores em 2016) e sua investigação é interessante por indicar o panorama acerca da participação feminina na política em municípios menores. Nas últimas eleições, em 2016, foram eleitas 04 mulheres dentre as 11 cadeiras do legislativo local: Imaculada Conceição da Silva Magalhães, Aparecida Nunes Gonçalves, Nadya Correa Massé, Rosy Anne Almodovas Rodrigues. No caso do poder executivo local, duas vice-prefeitas foram eleitas na história deste município: Dayana Mazzer (2012-2016) e Maria Helena Bertocco Martins (2016), portanto, apenas nas duas últimas eleições há a presença de mulheres integrantes da chapa vencedora ao Executivo local. Sendo de extrema importância o estudo e uma análise aprofundada acerca da participação feminina na política, tendo em vista que em sociedades regidas por matrizes culturais atravessadas por relações assimétricas de gênero, é um desafio para as mulheres destacarem-se em um universo predominantemente masculino, como é a política. No contexto deste artigo, questionamos como se dá a vivência da mulher em municípios menores. Pressupondo que o funcionamento da democracia implica na representação equilibrada da sociedade, especialmente nos parlamentos, questionamos a percepção das mulheres em cargos políticos públicos do atual período acerca da participação feminina na política no contexto de Cruzeiro do Oeste, sendo realizadas entrevistas anônimas com as mulheres com roteiro aberto e cujo resultado é analisado neste artigo.

Volatility Clustering at a Sector Level in the Chinese Equity Market
Authors: Perez Gerardo “Gerry” Alfonso
Published: July 2018

The issue of volatility clustering i.e., if periods of high volatility on stocks returns are typically followed by other periods of high volatility and vice versa, is analysed in this article at a sector level for the Chinese stock market. This analysis was performed with daily returns for the period from 2008 to 2017. When the entire dataset is analysed the statistical tests are rather consistent indicating that there is volatility clustering for all the major nine sectors (basic materials, communications, consumer cyclical, consumer non-cyclical, energy financial, industrial, technology and utilities). However, when each year is analysed independently the results are much more mixed with some sectors, such as technology companies, that could a priori look as a prime candidate for volatility clustering having less years with such feature present that other sectors such as for instance basic materials. The issue of volatility clustering at a sector level is of clear interest and can be used as another tool to optimize portfolio allocations. It is interesting to see that volatility clustering seems to be present when the statistical tests are performed over long periods of time but less so when the timeframe is shortened.

Regulatory roles of sugars in plant growth and development
Authors: Ciereszko Iwona
Published: June 2018

In recent years, several studies have focused on the factors and mechanisms that regulate plant growth and development, as well as the functioning of signaling pathways in plant cells, unraveling the involvement of sugars in the processes regulating such growth and development. Saccharides play an important role in the life of plants: they are structural and storage substances, respiratory substrates, and intermediate metabolites of many biochemical processes. Sucrose is the major transport form of assimilates in plants. Sugars can also play an important role in the defense reactions of plants. However, it has been shown that glucose, sucrose, or trehalose-6-phosphate (Tre6P) can regulate a number of growth and metabolic processes, acting independently of the basal functions; they can also act as signaling molecules. Changes in the concentration, qualitative composition, and transport of sugars occur continuously in plant tissues, during the day and night, as well as during subsequent developmental stages. Plants have developed an efficient system of perception and transmission of signals induced by lower or higher sugar availability. Changes in their concentration affect cell division, germination, vegetative growth, flowering, and aging processes, often independently of the metabolic functions. Currently, the mechanisms of growth regulation in plants, dependent on the access to sugars, are being increasingly recognized. The plant growth stimulating system includes hexokinase (as a glucose sensor), trehalose-6-phosphate, and TOR protein kinase; the lack of Tre6P or TOR kinase inhibits the growth of plants and their transition to the generative phase. It is believed that the plant growth inhibition system consists of SnRK1 protein kinases and C/S1 bZIP transcription factors. The signal transduction routes induced by sugars interact with other pathways in plant tissues (for example, hormonal pathways) creating a complex communication and signaling network in plants that precisely controls plant growth and development.
Investigating the Effects of Core Spun Yarns on the Quick-Dry Property of Towels
Authors: Yılönü Sait , Ünal Belkıs Zervent
Published: July 2018

The purpose of this study was to investigate the effects of core-spun yarn on the quick-dry property of towels. This study focused on five different raw materials (modal, cotton, polyester, bamboo, viscose) which are the most frequently used in towel production. Seven different core yarns and five different conventional yarns were produced with these fibres on a ring spinning machine. These yarns were used in the weft direction of the towels. Samples produced with the same ground and pile warp yarns were subjected to constant dyeing conditions. All samples were tested for strength, softness, hydrophilicity and quick drying. As a result, polyester core yarn on the towels did not negatively affect basic properties such as water absorbency, softness and strength. However, the usage of polyester core yarns provided better quick dry properties than that of conventional yarns.
Health related quality of life of the patients after transient ischaemic attack: is carotid endarterectomy (CEA) or carotid artery stenting (CAS) more influential?
Authors: Trystuła Mariusz
Published: July 2018

Although randomized trials have proven the benefit of revascularization with the use of carotid endarterectomy (CEA) or stenting (CAS) for appropriate patients, health care purchasers increasingly look beyond clinical outcome toward measures of health-related quality of life (HRQoL) in apportioning limited resources.

36 patients after TIA participated in this study. One group (n=18) had undergone CEA, whereas the second group (n=18) had undergone CAS. Both groups were matched according to age and sex. The Short Form 36 (SF-36) was used to assess the differences in patient-perceived HRQoL in two groups of patients who had suffered minor cerebral ischemic events.

No significant difference in health profile between the CEA and CAS was detected for the eight SF-36 domains. However, the CEA group rated a significantly improved change in general health after one year compared with the CAS group (p<0.001). A greater proportion of the CEA group comparing to the CAS group thought their treatment had been successful and that their health had been improved (p<0.001). Both groups shared the same level of anxiety over potential future cerebral ischemic events (p=0.3).

Patients' perception of HRQoL measured by the SF-36 domains was almost identical between the CEA and CAS apart from a small but significant improvement in self-reported overall health in the CEA group after one year follow up. HRQoL outcome measures may be of value in future clinical trials of cerebral revascularization to compare the effectiveness of carotid revascularization with the particular method of operation.
The mind and brain in time: implications for modern neuropsychology
Authors: Brown Jason W.
Published: July 2018

In this paper, I wish to describe the categorical nature of the mind/brain state from its origins in drive to the refinements of human cognition. Categories are concepts with a broader scope. The virtual quality of category members corresponds to the relation of whole and part. A successive individuation of categories is the foundational operation of the mind/brain state. There is a similarity to fractal theory and the mereology of wholes and parts, though categories are not sums or containers, members are virtual and the whole/part specification is qualitative, unlike the self-similar replications of fractal theory. The discussion takes up the problem of causal transmission between the mind and brain and within and across mental states, concluding that an assimilation model has more explanatory power than a strictly causal one, in keeping with the distinction of potential/actual from cause/effect. The idea that mind-brain interaction is causal introduces the possibility of subjectivity independent of a material substrate. This leads to speculation on a world soul animating the brain as part of nature, and conversely, the effort to extract all vestiges of spirit to leave a purely material organism and universe. There is no bifurcation of the mental and physical; rather a graded series of stages with properties of material and subjective entities that eventuate in human mentality. This conforms to a neutral monism. Duration is inherent in nature and evolves in company with organisms of increasing complexity.
The clinical image of memory, attention, and executive functions in a school-aged child with autoimmune epilepsy: A case study
Authors: Nowaczyk Natalia
Published: July 2018

The aim of this study was to identify specific aspects of the cognitive and socioemotional functioning of a school-age child with autoimmune-resistant epilepsy, and to provide a detailed explanation of the executive dysfunctions significant in this type of disorder.

A battery of neuropsychological tests and clinical trials were used to neuropsychologically diagnose an eight-year-old girl. Data from an interview with the patient’s mother, observational data, and the results of previous psychological and medical tests were also taken account. Neuropsychological diagnosis was performed in line with the clinical–experimental and psychometric -test models.

The patient’s current level of intellectual functions is below average. The patient obtained low results in tests examining executive functions, direct auditory memory, phonemic hearing, and visual–spatial organization. In comparison with children of her age group and with similar intelligence quotients, she obtained average results relating to tasks involving direct visual memory. No difficulty was seen in terms of semantic fluency, concentration, or persistence of the attention process.

Executive dysfunctions are among the dominant disorders seen in clinical settings; these significantly hinder the systematic and orderly organization of the child’s learning process. Such difficulties in cognitive functioning, but also in emotional and social functioning, can significantly impede the normal development of the child.

Published: July 2018

In this study, structural or physical properties such as the unevenness, hairiness and frictional properties of cotton-modal blended yarns were studied. For this purpose, 100% cotton, 50% cotton/modal and 100% modal ring spun yarns were produced in five different twist coefficients (αe: 3.5, 3.7, 4.0, 4.2, 4.5) and four different yarn linear densities (21, 25, 30 and 37 tex). General factorial design was used and the response surface was plotted for analysing the data. In conclusion, the most influential factors for the yarn characteristics were the yarn linear density and blend ratio. Contrary to expectations, the twist coefficient factor had a minor effect on yarn characteristics, especially on the friction coefficient.

Occasionally it can be located in less obviously place, which force the laryngologist to prevent more viligant diagnostic. A foreign body pounded within soft tissue of the oral cavity is the example. A case report of a metallic foreign body inherent in the tongue for more than six weeks before the final treatment is presented.

Aim: To evaluate acoustically evoked cervical and ocular vestibular miogenic potentials (AC cVEMP and oVEMP) findings in patients with Susac’s syndrome. We did not seek for a diagnostic replacement test in those patients, but we investigated if the combined application of AC cVEMP and oVEMPs might be helpful as an additional source of information about the disease.
Methods: To record VEMPs the EMG standardization method was used to continuously monitor and minimize the variability of the recordings. The stimuli were presented unilaterally one ear at a time. The waveforms were analyzed for the response presence, latency and amplitude.
Results: In the patient #1 stimulation resulted in responses on both sides with latencies within normal and symmetry limits for both c- and oVEMPs; however, the responses presented small amplitudes for cVEMPs. In patient #2, only cVEMPs were present. The P1 latencies were within normative values but amplitudes were low, in addition showing asymmetry between sides with right side amplitude being smaller.
Conclusion: The information provided by the combined application of AC cVEMP and oVEMP might be useful in diagnosis of Susac’s syndrome revealing additional information about the affected vestibular system and be of help in treatment and rehabilitation planning.

Published: July 2018

The paper deals with a concept of a missile vertical launch system using reaction control jets. The purpose of the study was a detailed investigation of a method optimizing fuel consumption in the first phase of the missile flight to increase the range and optimize the flight path. In the designed system the missile is ejected vertically and turned to the desired position by using corrective engines before the sustainer motor is started. The dynamics and controllability of the missile at low velocities were studied. The physical and mathematical model of the object has been described, taking into account the nonlinearities connected with the dynamics of the rocket itself, the disturbances caused by firing the rocket engine as well as some effects the unsteady aerodynamics. A method identifying the aerodynamic characteristics of the missile and an algorithm controlling the correction engines is presented. A prepared mathematical model of the missile was used to create a simulating environment. The results of numerical simulations in the form of graphs and tables are presented.

Introduction: Lower grades students participate in Physical Education lessons mainly for
pleasure, as well as for emotional and utilitarian reasons. For many students at this educational
stage their attendance in Physical Education classes is the only form of participation in organized
physical activity. Therefore, motor activities should provide children with the opportunity
for experiences of different kind and motivate them to physical activity. The aim of the research
was to find out what are the opinions of early school students on physical activities.
Material and methods: The research covered 256 students at the age of 7-10, 128 girls and 128
boys. The method of open categorized interview was applied to collect the empirical material.
Results: The results of the survey have shown that the vast majority of children expressed
their positive opinions on their participation in physical activities. The students enjoyed team
games and various exercises most. Nearly 9% of the examined were dissatisfied with the lack
of discipline during the lesson and not observing fair play principles by their classmates during
exercises. The said dissatisfaction increased with age. The examined did not show much interest
in swimming classes, and the 9-10 age group showed no interest in them at all.
Conclusions: The large majority of students, irrespective of their age, are willing to participate
in motor activities.
STUDY OF THERMO-MECHANICAL PROPERTIES OF AGED HOMOGENEOUS SOLID ROCKET PROPELLANT ACCORDING TO STANAG REQUIREMENTS
Authors: Czerwińska Magdalena , Prasuła Piotr
Published: July 2018

Proper operation of rocket motor depends significantly on thermo-mechanical properties of propellant used. For this reason it is important that characteristics of a particular propellant versus the time and temperature pass a thorough investigation to assess its operation at different conditions. The paper illustrates investigations of ageing process influencing thermo-mechanical properties of homogeneous rocket propellant. A selected type of rocket propellant was subjected to accelerated ageing in conditions specified in AOP-48 document to establish in the next step its thermal and mechanical characteristics (between all the temperature of glass transition and decomposition). The ageing of propelling explosives causes the reduction of stabiliser content deciding about thermo-mechanical properties of propellant and for that the percentage of effective stabiliser and its loss were identified by liquid chromatography HPLC. Thermal properties were investigated by differential scanning calorimetry. Thermal analyses were carried out according to STANAG 4515. Mechanical characteristics were tested by dynamic mechanical analysis (DMA) in line with STANAG 4540.

Physical activity (PA) is an important modifiable risk factor for endometrial cancer (EC). PA has been studied using diverse measures including metabolic equivalent of task MET, duration, frequency and subjective levels, but for practical reasons most of epidemiological studies use questionnaires rather than objective measures to document PA. Moderate-intense daily PA has a protective effect and have a 20-40% reduced risk of EC. In this rewiev complex and variable behaviour, and the ability of epidemiological studies to determine the relationship between PA and EC has been discussed.

According to recent society guidelines, upper gastrointestinal bleed initial approach includes assessment of hemodynamic status, fluid resuscitation if necessary, transfusion strategy to target hemoglobin above 7 (g/dL), use of intravenous proton pump inhibitor and generally upper endoscopy within 24 hours. We present a case of a 26-year-old woman who sought treatment after one episode of hematemesis and pre-syncope. She had a similar presentation three months earlier and received interventional radiology-guided mesenteric angiography and the use of multiple coils to embolize a 1.5-cm deep punched-out duodenal ulcer. Migration of the coil was noted on endoscopy within the previously described ulcer. Coil migration is expected to occur in up to 3% of cases of endovascular embolization. However, migration into the duodenum is uncommon and could have actually been a contributing factor to the current bleed.
Preparation and investigations of electrical
and optical properties of thin composite
layers PAN/SiO2, TiO2 and Bi2O3
Authors: Matysiak W. , Jarka P. , Tański T.
Published: July 2018

Purpose: The aim of this study was to present the influence of mass concentration of the
reinforcement phase on the structure and optical properties of the obtained composite thin
films with a polymer matrix reinforced by SiO2, TiO2 and Bi2O3 nanoparticles, produced by
the spin-coating method.
Design/methodology/approach: To produce composite materials, 10% wt. polymer
solutions of polyacrylonitrile (PAN) and N, N - Dimethyloformamide (DMF) were used,
containing nanoparticles with a mass concentration ratio of, sequentially: 0, 4, 8, 12%. The
morphology, structure and chemical composition of the obtained thin films were determined
on the basis of surface topography images, taken using atomic force microscopy (AFM)
and a scanning electron microscope (SEM) with EDX and QBSD spectrometers. In order
to analyse the optical properties, UV-Visible spectroscopy (UV-Vis) was used. The width of
the band gap was determined on the basis of the absorption spectra of radiation (UV-Vis).
Findings: The carried out morphology and surface structure research showed that with
increasing mass increased porosity of the produced coating surface was observed. In
addition, the greater the diameter of the applied ceramic nanoparticles, the more noticeable
this effect was. The analysis of the optical properties of the obtained nanomaterials, carried
out based on the registered spectra in absorption function of the wavelength, revealed a
strong absorption of this type of layers under ultraviolet radiation.
Research limitations/implications: The nanostructured materials as components
provides nanocomposite optical properties, such as absorption and width of the energy gap.
In addition, nanoparticle content causes changes of the surface morphology, which is an
important parameter of thin films in potential applications.
Originality/value: The properties of films depend not only on the individual components
used, but also on the morphology and the interfacial characteristics.
