Authors: Raider Leandro
Published: November 2019

A busca pelo melhor resultado nas partidas de futebol passou a ser um ato devidamente estudado e pesquisado, porém há uma carência de pesquisa a respeito da potência aeróbia e os estágios de maturação dos jovens atletas, representando uma grande perda de informações para os profissionais atuantes na área. O presente estudo tem como objetivo identificar os estágios de maturação e sua influência nos valores de potência aeróbia nas categorias infantil e juvenil. A amostra foi composta por cento e cinquenta (N = 150) jogadores de futebol do sexo masculino, com idades compreendidas entre 14 e 17 anos. Para a avaliação da potência aeróbia, foi utilizado o teste de Yo-Yo Recovery Intermitente ní­vel I. As avaliações maturacionais foram feitas através do protocolo de Anner (1962) que divide em 5 os estágios de maturação pubiana. Foram realizadas as estatí­sticas descritivas (média, desvio padrão e coeficiente de variação) e, para verificar as diferenças das variáveis dependentes entre os estágios maturacionais, foram realizados os testes não paramétricos Mann Whitney U e Kruskall Wallis. Na categoria Infantil encontramos atletas nos estágios de maturação 3 (VO2 46,39 ml/kg-1. min-1), estágio 4 (VO2 45,40 ml/kg-1. min-1) e estágio 5 (VO2 46,20 ml/kg-1. min-1). Já na categoria juvenil encontramos atletas apenas nos estágios 4 (VO2 47,3 ± 1,8 ml/kg-1. min-1) e estágio 5 (VO2 48,1 ± 1,6 ml/kg-1. min-1).(p = 0,03). O presente estudo concluiu que na categoria infantil não houve diferenças significativas entre os estágios de maturação 3, 4 e 5 e os valores de potência aeróbia. Entretanto, na categoria juvenil ocorreu diferenças significativa entre os valores de potência aeróbia e os estágios 4 e 5.Palavras-chave: futebol, maturação e potência aeróbia.

Poor graft function is a serious complication following allogeneic hematopoietic stem cell transplantation. Infusion of CD34+-selected stem cells without pre-conditioning has been used to correct poor graft function, but predictors of recovery are unclear. We report the outcome of 62 consecutive patients who had primary or secondary poor graft function who underwent a CD34+-selected stem cell infusion from the same donor without further conditioning. Forty-seven of 62 patients showed hematological improvement and became permanently transfusion and growth factor-independent. In multivariate analysis, parameters significantly associated with recovery were shared CMV seronegative status for recipient/donor, the absence of active infection and matched recipient/donor sex. Recovery was similar in patients with mixed and full donor chimerism. Five -year overall survival was 74.4% (95% CI 59-89) in patients demonstrating complete recovery, 16.7% (95% CI 3-46) in patients with partial recovery and 22.2% (CI 95% 5-47) in patients with no response. In patients with count recovery, those with poor graft function in 1-2 lineages had superior 5-year overall survival (93.8%, 95% CI 82-99) than those with tri-lineage failure (53%, 95% CI 34-88). New strategies including cytokine or agonist support, or second transplant need to be investigated in patients who do not recover.

Semantic of the form in rock-music: art-pedagogical aspect (on example of hardand-heavy)
Authors: Vasylieva Larysa
Published: November 2019

Purpose of Article - description of the semantic features of the hard-and-heavy musical composition in artistic and pedagogical aspects - the following tasks are specifically applied: individual perspectives of the study of semantics in rock music; need an organization theme), describe the structure and semantic model of hard and
heavy compositions. Methodology relies on an integrated approach with the use of system-structural, functional and comparative methods, which allows to explore the characteristics of musical composition's semantics in hardand-heavy at the intonational-thematic, genre, compositional levels. Scientific novelty consists in describing the models of the structural and semantic organization of hard-and-heavy compositions on the basis of a study of the processes of shaping, thematic and structural organization.
Hard-and-heavy uses various types of forms - from simple to complex, mirror-symmetric, open, alternative, which are based on one of the three types of thematic organization: monoriff, polyriff, spiral. Structural models of hard-and-heavy musical forms emerge based on the interaction of genre features of vocal and instrumental music. Each structural model corresponds to a generalized semantic model with a specific range of values. The guiding lines for semantic interpretation are representations of typical forms. The semantic model of a typical hardand-heavy composition has several particular models that play the role of a meaningful scenario, define the functional and dynamic profile of the piece, and create the semantic field of this form.
Semantic analysis of the rock-piece`s form, as a component of the operational level of artistic and pedagogical analysis, provides an awareness of the joint action of the means of musical expression in their interconnection and conditionality of content. It reveals the structural features of a piece of music, facilitating the process of perception and providing active influence of musical images on the listeners

Landslides almost every year occur in Indonesia, this rare landslide that can be detected early. because so far the prediction of slope slope is difficult. To predict the calculation requires the analysis and stability of the slope manually. This manual calculation process is quite long and long process. The calculation data and slope stability analysis are in the form of slope measurement, the work is quite tiring and risky for the researcher, and also the scope of the slope that can be measured is only narrow. In addition to slope inclination data, for slope analysis also requires soil data to be sampled and testing in a geotechnical laboratory. This study investigated slope stability by creating landslide models using Digital Elevation Models (DEM), and Geoslope programs. Slope model was analyzed from DEM and landslide stability analysis using Geoslope. From this concept we are expected to analyze landslide / stability slope quickly and accurately without risk for researcher.

Published: November 2019

Energy demand is increasing day by day be cause of the step up of population, rising living standards, rising energy prices, global warming and climate change, developments in industry and tech nology in developing countries. In order to meet this increasing energy demand, it is not possible to increase production only due to limited energy resources. Therefore existing energy sources need to be used in the most efficient way. One of the most important means of reaching this target is the effi cient use of energy and its saving. Tunnel illumina tion is one of the areas of efficient and saving use of energy. In this study, high pressure sodium (HPS) and light emitting diode (LED) luminaires usage are compared to Buzlup?nar tunnel, which is a short tunnel in Bitlis province. It has also been found that illumination with LED luminaires is more efficient and economical in tunnel illumination instead of HPS.
A Review of Dimensionality Reduction Techniques for Processing Hyper-Spectral Optical Signal
Authors: del Águila Ana , Efremenko Dmitry S. , Trautmann Thomas
Published: November 2019

Hyper-spectral sensors take measurements in the narrow contiguous bands across the electromagnetic spectrum. Usually, the goal is to detect a certain object or a component of the medium with unique spectral signatures. In particular, the hyper-spectral measurements are used in atmospheric remote sensing to detect trace gases. To improve the efficiency of hyper-spectral processing algorithms, data reduction methods are applied. This paper outlines the dimensionality reduction techniques in the context of hyper-spectral remote sensing of the atmosphere. The dimensionality reduction excludes redundant information from the data and currently is the integral part of high-performance radiation transfer models. In this survey, it is shown how the principal component analysis can be applied for spectral radiance modelling and retrieval of atmospheric constituents, thereby speeding up the data processing by orders of magnitude. The discussed techniques are generic and can be readily applied for solving atmospheric as well as material science problems.
How to measure respiratory mechanics during controlled mechanical ventilation
Authors: Giani Marco , Bronco Alfio , Bellani Giacomo
Published: November 2019

Bedside measurement of respiratory mechanics allows to closely monitor the lung function in critically ill patients. The two fundamental parameters describing the respiratory system mechanics are resistance and compliance. Resistance of the respiratory system describes the opposition to gas flow during inspiration. During volume-controlled ventilation, resistance can be calculated as the ratio between the peak to plateau pressure drop and the resulting flow rate. Compliance describes the elastic property of the respiratory system, comprising the lung and the chest wall. It is the ratio between a change in volume (i.e. tidal volume) and the corresponding change in pressure, calculated as the difference between plateau pressure and total positive end-expiratory pressure, measured by end-inspiratory and end-expiratory manual occlusion, respectively. In this review, we describe how to measure respiratory mechanics at the bedside, starting from the physiological background of the equation of motion of the respiratory system.  (Intensive care)

Neurofibromatosis type 1
(NF1) is the most common autosomal dominant neurocutaneous syndrome with the
estimated prevalence ranging from 1 in 3000 to 1 in 4000 individuals and wide
phenotypical variability. NF1 is caused by autosomal dominant heterozygous
mutations in the neurofibromin gene which is located on the chromosome 17
(17q11.2). Phenotypically, NF1 patients have a very heterogeneous clinical
phenotype. In this study, a novel frameshift NF1 variant was identified in a
Croatian family with NF1 (mother and two daughters). The novel variant c.

stop signal (p.His1494Glnfs*7) in the NF1 gene. Our study showed that even when
the same germline NF1 variant has been identified, there is still huge phenotypic
variability in patients even within the same family, and it makes prognosis of
the disease more complex. The development of next-generation sequencing
technologies which allow rapid and accurate identification of disease-causing
mutations becomes crucial for molecular characterization of NF1 patients as
well as for patient follow-up, in the context of genetic counseling and
clinical management of patients.

Elevated blood pressure
(BP) in pregnancy, especially gestational hypertension and preeclampsia, can
lead to serious pregnancy complications and adverse birth outcomes. A large
body of literature already reported the effect of baseline body mass index (BMI)
on changes in blood pressure during pregnancy. The aim of this study was
therefore to define trajectory of systolic (SBP) and diastolic (DBP) blood
pressure in 308 pregnant participants from the CRIBS study (146 from the
mainland and 162 from the islands of Brač and Hvar) and to analyze the
association of blood pressure with maternal BMI prior to pregnancy and maternal
anthropometry during pregnancy. Pregnant women included in the CRIBS study had
no history of chronic diseases. The BP of CRIBS participants was measured at
least once in each trimester, and maternal pre-pregnancy weight was
self-reported. All analyses were performed using SPSS 10.0. Results showed that
pre-pregnancy BMI was the strongest predictor of pregnancy blood pressure. This
association was evident for pre-pregnancy BMI independently (p<0.001), and
it also persisted after adjusting for maternal age, education, income, parity,
smoking and physical activity (p<0.05). The association between maternal
anthropometry during pregnancy and blood pressure was not as strong and was
therefore less informative. The study reinforces the role of BMI on SBP and DBP
and highlights its importance during prenatal care monitoring. Significant
association also emerged between blood pressure in pregnancy and place of
residence (mainland vs. island). Women on Dalmatian islands have lower
educational level, higher pre-pregnancy BMI and different levels of blood
pressure than women from the mainland (namely, higher SBP and lower DBP). Such
comparisons between mainland and island populations are valuable, because they
can, in the long term, lead to better maternal health care on the islands.

Angiogenesis has a significant
part in the pathogenesis of hematological malignancies, such as leukemia and
myelodysplastic syndromes (MDS). We evaluated the relationship between
morphometric, morphological and clinical features of MDS. Blood vessels of 31
newly diagnosed MDS bone marrow biopsies were immunohistochemically analyzed
using CD34 and compared with 8 controls and 13 chronic myelomonocytic leukemias
(CMML). MDS were categorized into three risk groups: low-, intermediate- and
high-risk MDS.
Microvascular density (MVD) and major and minor
axis length were analyzed using digital image analysis. Overall, MDS had
significantly higher MVD and lower minor axis values than the control group and
CMML. High-risk MDS had significantly higher MVD compared to the controls,
while all MDS risk groups had lower minor axis values than the control
group. Increased minor and major axis
values were prognostic predictors of shorter overall survival in all MDS risk
groups and CMML patients. In conclusion, angiogenesis presents one of the
essential factors in MDS pathogenesis and progression characterized by
descriptive marrow microvascular network transformation. The size-related
features are powerful indicators of survival in MDS patients.

Knowledge about consumers is the key to planning a marketing strategy in the company, the customer can be the most valuable asset so the company needs to maintain and create equity. The development of technology is very rapid from the development of new product markets to meet the increasing needs of society as well. business people lead to the establishment of many shopping facilities that offer services and facilities that make it easier, then this can attract consumers. Impulsive buying and unplanned buying by some researchers are not differentiated. Semuel, (2005) does not distinguish between unplanned buying and impulsive buying but gives important attention to researchers, customers must focus on the interaction between point of sale with buyers who are often ignored. Personal selling is a form of individual communication where a salesperson deals directly with potential buyers and tries to influence them to buy their products or services. Hedonic shopping according to Semuel (2005) reflects an instrument that directly presents the benefits of experience in spending, such as pleasure, new things. Multiple Linear Regression Analysis is used to analyze the effect of several independent or independent variables (X) on one dependent or dependent variable (Y) together.

At the paper results of study of air distribution at elongated railway tunnels from piston effect of trains are represented. Simulation was carried out on the example of movement of freight train with length of 1 km at tunnels with length 3 and 6 km by numerical experiment in ANSYS Fluent software pack. As a result of the study, dependences of air pressure to front and rear surfaces of train on its position in the tunnel and on value of aerodynamic resistance of the gap between train and wall of the tunnel are obtained. The results have been used for development of quasi-dynamic model of piston effect of trains for solution of static air distribution problems on network models. Comparison of air discharge at various tunnel cross-sections obtained using ANSYS Fluent pack and network model shows satisfied repeatability. In that case, time of problem solution for a tunnel with length 3km on network model in 4·105 lower than on volume model. It has important practical meaning for multivariant calculations during designing of ventilation systems at railway tunnels.
DESTRUCTION OF GROUND BREEDS BY SHOCK LOADING THROUGH BULK MATERIAL IN SLEEP
Authors: Kyu Nikolai
Published: November 2019

The principle of the formation of an oriented crack by splitting a rock in a given plane by shock loads through the bulk material in the bore holes is discussed. It is shown that the transmission of shock loads from wedges through the bulk material to the walls of the holes in the rock does not cause local stresses, causing the appearance of random micro discontinuities that can change the orientation of the plane of the formed crack. The technical means for the implementation of this principle and the engineering calculation of their working bodies are given.

Published: November 2019

Intensive development of goal deposits by means of implementation more productive machinery causes the increasing of fire and explosion hazardous situations in mines due to gas-dynamic effects. Mass media regularly reports about tragic events related to gas explosions and mass fatality in coal mines in Russia, neighboring and foreign states. General topic is the creation of composite material based on solid particle of coal and rocks, gases (methane and hydrogen) and moisture and study of mechanisms of initiating action of accident dynamic effects due to mining. Study objective is creation of laboratory facilities for obtaining composite materials “coal-gas-moisture” in the form of coal core-sample and experimental investigation of its physical and mechanical properties. Special stand is developed for obtaining and study of composite materials “coal-gas-moisture”. Dependences of changes of physical and mechanical properties of core-samples on pressure are obtained experimentally by the example of various materials (coal, limestone, graphite, etc.) using the developed stand. Features of change of temperature, deformation of briquette mass, density after pressure increasing up to 200 MPa are established by the example coal of D-make of different coarseness. It is shown that temperature of coal briquette increases maximum up to 14 ºС at air pressure and up to 10 ºС at vacuum. The stand allows to carry out physical simulation of coal and rocks considering its composition. Scientific novelty is the creation of composite materials imitating natural coal and rocks under specified physical and mechanical conditions.
