Published: June 2019

Due to low working temperature, high energy density and low pollution, proton exchange fuel cells have been investigated under different operating conditions in different applications. Using platinum catalyst in methanol fuel cell leads to increasing the cost of this kind of fuel cells which is considered as a barrier to the commercialism of this technology. For this reason, a lot of efforts have been made to reduce the loading of the catalyst required on different supports. In this study, carbon black (CB) and carbon nanotubes (CNT) have been used as catalyst supports of the fuel cell as well as using the double-metal combination of platinum-ruthenium (PtRu) as anode electrode catalyst and platinum (Pt) as cathode electrode catalyst. The performance of these two types of the electro-catalyst in oxidation reaction of methanol has been compared based on electrochemical tests. Results showed that the carbon nanotubes increase the performance of the micro-fuel cell by 37% at maximum power density, compared to the carbon black. Based on thee-electrode tests of chronoamperometry and voltammetry, it was found that oxidation onset potential of methanol for CNT has been around 20% less than CB, leading to the kinetic improvement of the oxidation reaction. In addition, the active electrochemical surface area of catalyst has been increased up to 90% by using CNT compared to CB which shows the significant rise of the electrocatalytic activity in CNT supported catalyst with 62% increase in current density of methanol oxidation reaction respect to CB supported one. Moreover, the resistance of CNT supported sample to poisonous intermediate species has been found 3% more than CB supported one. According to the chronoamperometry test results, it was concluded that the performance and sustainability of NCT electro-catalyst shows remarkable improvement compared to CB electro-catalyst in long term.
Serum Agrin and Talin, Two Muscular Proteins, are Significantly Increased in Major Depression and Increased Agrin and Lowered Creatine Phosphokinase are Associated with Chronic Fatigue and Fibromyalgia Symptoms in Depression

Published: June 2019

Chronic fatigue and fibromyalgia symptoms frequently occur in major depressive disorder (MDD). The pathophysiology of these symptoms may in part, be ascribed to activated immune pathways, although it is unclear whether muscular factors play a role in their onset. The aim of the present study is to examine the role of muscle proteins in major depression in association with symptoms of chronic fatigue and fibromyalgia. We measured serum levels of agrin, talin-2, titin, and creatine phosphokinase (CPK) as well as the FibroFatigue (FF), the Hamilton Depression Rating Scale (HAM-D) and the Beck Depression Inventory (BDI-II) in 60 MDD patients and 30 healthy controls. The results show a significant increase in agrin and talin-2 in MDD patients as compared with controls. There were highly significant correlations between agrin and HAM-D, BDI-II and FF scores. Agrin, but not talin or titin, was significantly and positively associated with all 12 items of the FF scale. We found that a large part of the variance in HAM-D (47.4%), BDI-II (43.4%) and FF (43.5%) scores was explained by the regression on agrin, smoking, female sex (positively associated) and education (inversely associated). CPK was significantly and inversely associated with the total FF score and with muscle and gastro-intestinal symptoms, fatigue, a flu-like malaise, headache and memory, autonomic and sleep disturbances. These results suggest that aberrations in neuromuscular (NMJs) and myotendinous junctions may play a role in MDD and that the aberrations in NMJs coupled with lowered CPK may play a role in symptoms of chronic fatigue and fibromyalgia in MDD. Moreover, the increase of agrin in MDD probably functions as part of the compensatory immune-regulatory system (CIRS).

Published: June 2019

Carbon dots (C-dots) are a new type of fluorescent nanoparticles that can be readily synthesized from natural sources, such as cassava’s peels. In this work, C-dots were synthesized from cassava’s peels using low temperature green synthesis based. The Green synthesis techniques were done by using water as a solvent non-chemical and natural sources. The Synthesis was done using various concentrations of precursor from 0.25%, 0.50%, 1.0% and 2.0%. Optical properties of C-dots were characterized using spectrophotometer UV-Vis, photoluminescence (PL) and time resolved photoluminescence (TRPL). The concentration of precursor lead to differences in molecular density and content of preparation thus affecting optical properties. The performance of C-dots optical properties were dominated by the transition of electrons n–π* on structure aromtic C=O which originate from the surface of C-dots. The result of C-dots sample with a concentration of 2.0% precursors has the best emission effiency. This provides the potential for C-dots cassava’s peels in the aqueous solution to be applied as cellular bioimaging and biosensing metal ions and salts.

Authors: Hadiningrum Kunlestiowati , Muldani Ratu Fenny
Published: June 2019

Boyle’s Law describes the inverse relationship between absolute pressure and air volume, if the temperature is constant in a closed system. Gay Lussac’s Law states that the pressure of a gas mass is directly proportional to the absolute temperature of the gas, when the volume is held constant. The macroscopic quantity associated with both laws includes the number of moles of gas. The purpose of the study is to calculate the number of moles of gas through Boyle’s Law and Gay Lussac’s Law experiments. The experimental results were confirmed by calculating the number of moles theoretically, so that it can be concluded that the experimental device settings which the closest to the theoretical results. The Boyle’s Law experimental results with a pipe cross-sectional area of 54.08 mm2, at a temperature of 295 K obtained 4.67 x 10-4 moles, its relative uncertainty is 7.60%, at a temperature of 299.1 K obtained 3.97 x 10- 4 moles, the relative uncertainty value is 0.51%, and at a temperature of 299.5 K obtained 5.20 x 10-4 moles, the relative uncertainty value is 12.56%. The average relative uncertainty value of the three experiments is 6.89%. The results of the Gay Lussac’s Law experiment, at a gas volume of 0.578 x 10-3 m3, obtained the number of moles in a row of 1.38 x 10-2 moles, 1.83 x 10-2 moles and 1.33x 10-2 moles, theoretical calculation of 2.14 x 10-2 moles. The average value of the relative uncertainty of the three experiments is 24.3%. Based on these results, it can be concluded that the results of calculating the number of moles through Boyle’s Law experiments are closest to theoretical calculations.

Published: June 2019

Background: Humic acid (HA) fertilizer was previously considered to be able to enlarge the effective absorption area of roots and promote plant root growth. While recent evidences suggested that certain root-associated microbes might be able to mitigate the negative responses of drought stress. In this study, we sought to explore abundance and diversity of root-associated bacterial communities under humic acid (HA) fertilizer and drought stress treatments.
Results: We collected rhizospheres of three groups (HA, drought, and control) and microbiomes from bulk soil during flowering period in maize. We obtained the bacterial community for the V4 region of the 16S rRNA gene using Illumina Hiseq2500. By analyzing the sequencing data, we identified 40 bacteria phyla across samples. The abundance level of the 12 bacterial communities at phyla level are significantly different in the rhizosphere of the drought treated samples as compared to the controls, two of which, Actinobacteria and Bacteroidetes, were also significantly enriched (FC=1.79, adj.P=0.043) and depleted (FC=0.70, adj.P=0.086) in HA fertilizer treated samples.
Conclusions: The results suggested that the delayed responses of plants to drought stress in HA fertilizer treated soils might be through supply a resource of substance to recruit drought-resistance microbiomes.

Authors: Manjunath Adarsh , Dielubanza Elodi J. , Amarasekera Channa , Kielb Stephanie J.
Published: June 2019

Background

A significant proportion of renal transplant recipients experience recurrent urinary tract infections. This can ultimately compromise graft function but no protocol exists for diagnosis and management in these patients. We sought to evaluate the utility of urodynamics in renal transplant recipients with recurrent urinary tract infections.

Methods

Our institution’s electronic data warehouse was queried to identify renal transplant recipients who received urodynamics between 1999 and 2013. A retrospective review of urodynamic findings, management, and graft outcomes was performed for nine patients who had a diagnosis of recurrent urinary tract infections. Mean follow-up was 2.46 years.

Results

On urodynamics, mean bladder capacity was 392mL and post-void residual urine volume was >100mL in 3/9 patients. All patient had normal bladder compliance and voiding pressures. Native ureteral reflux was seen in one patient with a history of a febrile urinary tract infection and 4/9 had reflux in a transplant kidney. Mean creatinine at last follow up was 1.47. The patient with febrile infections had creatinine >3 from a nadir of <1. All patients were managed with medical therapy and none referred for surgery. No patients required dialysis.

Conclusions

In renal transplant recipients with recurrent urinary tract infections and no pre-existing voiding abnormalities, urodynamics did not identify functional or anatomic abnormalities that impacted management. Urodynamics may have a limited role as a diagnostic modality in this cohort after failure to respond to medical therapy.
Corporate rating forecasting using Artificial Intelligence statistical techniques

Published: June 2019

Forecasting companies long-term financial health is provided by Credit Rating Agencies (CRA) such as S&P, Moody’s, Fitch and others. Estimates of rates are based on publicly available data, and on the so-called ‘qualitative information’. Nowadays, it is possible to produce quite precise forecasts for these ratings using economic and financial information that is available in financial databases, utilizing statistical models or, alternatively, Artificial Intelligence techniques. Several approaches, both cross section and dynamic are proposed, using different methods. Artificial Neural Networks (ANN) provide better results than multivariate statistical methods and are used to estimate ratings within all the range provided by the CRAs, obtaining more desegregated results than several proposed models available for intervals of ratings. Two large samples of companies ‘public data’ obtained from Bloomberg are used to obtain forecasts of S&P and Moody’s ratings directly from these data with high level of accuracy. This also permits to check the published rating’s reliability provided by different CRAs.

Published: June 2019

Economic development of any country depends on its natural resources, as well as availability of human resource. Every aspect, actions and activities in an organization involve people. Out of various resources, the human resource management has become critical resource for gaining the competitive edge. Today, most of the countries are giving attention and putting their effort to the development and training of their human resources. Training is effort initiated by an organization to foster learning among its workers. Training and development are a continuous effort designed to enhance employee learning, as well as his/her creativity, which is helpful in improving employees’ competence and organizational performance. The present research work examines the moderating and mediating role of organizational climate between employees training and creativity. In a survey of 324 employees working in various SME of Dehradun area, it was found that both employee creativity and employee learning foster organizational climate. Further, the mediation effect of organizational climate on learning and creativity is different. The study shows that creativity is partially mediated, but learning has no significant effect on organizational climate. The study suggests that companies must focus on training their employees so that employees become creative and learn new practices for improving their competencies at work. The study also suggests finding the means of improving organizational climate because of its rich contribution towards improving employee creativity and learning.
The symmetrical cell eigenfrequency method for periodic structure stop-band definition
Authors: Hvatov Alexander
Published: June 2019

The Floquet theory that is used in order to find the stop-bands is not defined for non-linear cases. The eigenfrequencies of a symmetrical periodicity cell can serve as alternative indicators of stop-band boundaries. In the linear cases, eigenfrequencies of a structure with symmetrical boundary conditions are exactly placed on stop-bands boundaries. In the non-linear cases, however, the notion of the Floquet zones are not clearly defined. However, the eigenfrequencies method show the stop-band positions that agree with the energy flow analysis. In the cases are considered, the axial rod vibration, the radial-periodic membrane case, the axial rods connected with spring with non-linear stiffness.
On oscillations of a vibratory jaw crusher with asymmetric interaction of the jaws with the processed medium
Authors: Panovko Grigory , Shokhin Alexander , Lyan Ilya
Published: June 2019

This paper is devoted to the problem of providing the required synchronous modes of oscillations of a jaw crusher with self-synchronizing inertial vibration exciters. The described mathematical model of the crusher takes into account the mechanical properties of the medium being processed and the possible asymmetry of its contact with the crusher’s working bodies – the jaws. A numerical analysis of synchronous modes of crusher vibrations with different asymmetries of the initial location of the processed medium relative to the jaws is done. It is shown that for given oscillation excitation frequencies, the non-simultaneous contact of the processed medium with the jaws can lead to a change in the types of synchronous vibrations of the jaw crusher.

Published: June 2019

Abrasive flow machining technology is a new type of precision machining technology. Due to its unique rheological properties, it can process any complex structure and size parts to meet the requirements that conventional machining cannot meet. Combined with the turbulent flow characteristics of the abrasive flow, the large eddy simulation numerical method is used to simulate the machining process of the abrasive flow. The influence of different sub-grid scale models on the simulation results is discussed. Taking curved tube as the research object, the static pressure, dynamic pressure and velocity of different sub-grid models are analyzed to find the best sub-grid scale model. Large eddy simulation method is used to simulate the complex flow channel parts, and the best sub-grid scale model suitable for complex flow channels is determined, which reveals the grinding and polishing rule of abrasive flow and provides academic support for future research. Therefore, it has frontier and important research value.

Authors: Buyanova Irina , Altukhov Igor , Tsuglenok Nikolay , Krieger Olga , Kashirskih Egor
Published: June 2019

The paper describes physical characteristics of drying animal- and plant-based raw materials with pulsed infrared emitters. Furthermore, it discusses how to select and use infrared emitters to produce high quality products with a long shelf-life. Using an experimental facility, we identified basic patterns of changes in the heat flux density. We also analysed the drying thermograms and assessed the influence of process factors on the removal of moisture from raw materials and the preservation of biologically active substances in dried and concentrated products. We determined specific kinetics of drying in different modes of power supply and selected the most efficient pulsed cera- mic emitters. These emitters had a high rate of heat transfer and an ability to accurately target molecular bonds, thus reducing the drying time and energy costs. Mathematical modelling enabled us to obtain specific values of process parameters for pulsed infrared drying of plant materials. The heating time constant was calculated for root and tuber vegetables, depending on their moisture content and size. The study showed that root and tuber vegetables should not be heated to more than 60°C when irradiated with a 500 W medium-wave emitter at a working distance of 250 mm during a full 10-minute cycle. The optimal modes of drying liquid products with milk and plant proteins included a heating power of 400 W, a radiant heating temperature of 60°C, and a layer thickness of 10 mm. The selected modes of pulsed infrared drying of sugar-containing root and tuber vegetables reduced the duration of moisture removal by 16–20% and cut energy costs by 16.6%. This unconventional method of infrared drying of whole milk, whey, whey drinks, and milk mixture preserves beneficial microflora and increases the nutritional value and shelf-life, with a pos- sible content of chemically bound water of polymolecular and monomolecular adsorption ranging from 10 to 15.58%.
Environmental regulations in Russian food security
Authors: Lisina Natalia
Published: June 2019

The present research features the legal effect of environmental regulation on food security in the Russian Federation. The author analyzed the system of environmental regulation together with its legal instruments, and gave a legal assessment of its efficiency in providing safe environment and food products. The efficiency of the mechanism of environmental regulation affects the safety of products. However, the system of environmental regulation is large- ly represented by sanitary and hygienic standards and does not fully meet modern challenges. Meant as a basis for environmental and food security, the current environmental regulation takes into account neither local conditions nor the level of aggregate anthropogenic load on environment, thus failing to ensure the production of safe, high-quality food products. The study proves that there is an inextricable link between environmental regulation and environmen- tal safety, which has to be taken into account in state policy planning. By providing environmental safety, environ- mental regulation serves as the main means of food security. The author proposes to develop legislation on various types of environmental standards that would ensure food quality and security. The measures of food quality and se- curity should be based on the principles of environmentalisation and sustainable agriculture.

Subjects of this research were: green mussels (C1), marinated green mussels (C2), and marinated green mussels packaged in modified atmosphere (M1, M2, and M3). A percentage of O :CO :N was 5:50:45 for M1, 5:70:25 for M2, and 5:90:5 for M3. Microbiological, hemical, and sensory qualities of the samples were analyzed during storage at 4°C for 30 days. The results indicate

that glycogen, iron, and zinc contents as well as pH values decreased in all the cases during storage. In addition, TVB-N and TBARS values as well as mesophilic and lactic acid bacteria increased with time in all the samples. The number of psychrophilic bacteria in marinated samples was small or not detected at all. Escherichia coli, Staphylo- coccus aureus, Salmonella spp. and Vibrio cholera were below standard values. Based on sensory acceptability, the shelf-life of C1, C2, M1, M2, and M3 samples was 12, 18, 24, 24, and 27 days, respectively.
MultiRain: a GIS-based tool for multi-model estimation of regional design rainfall for scientists and practitioners
Authors: Grasso Susanna , Libertino Andrea , Claps Pierluigi
Published: June 2019

Extreme rainfall estimation is a long-standing challenge for hydrological hazard assessment and infrastructure design, particularly if considering the need to deal with climate change. Advances in statistical methods and in rainfall data availability allow for frequent updates of regional rainfall frequency analyses. These allow for new estimates that, however, cannot simply replace older ones in the risk management, due to technical, socio-economic and legislative reasons. To preserve compatibility between old and new regional estimates a multi-model approach could be used, where model uncertainties can be combined to help reach a final decision. To make this possible, one has to face the uneasy retrieval of data and results of older analyses and, quite often, non-trivial areal rainfall estimates are needed with all methods. To give an answer to these technical needs, a tool named MultiRain has been developed. The tool computes depth–duration–frequency (DDF) curves, both related to a point and integrated over an area, from multiple regional statistical analyses. The MultiRain procedure is based on Python scripting, geographic information system (GIS) functions and web technologies, and can be performed via web browser or in a desktop GIS environment. A demonstration version has been built using four different regional analyses proposed in a 20-year period for the north-west of Italy.

From random Brownian motion of particles to high automation laboratory: a brief history of correlation time (Preprint)
Authors: Di Stasio Enrico , Berruti Federico , Arcovito Alessandro , Romitelli Federica , Antenucci Mirca , De Cristofaro Raimondo , Urbani Andrea
Published: June 2019

BACKGROUND

Laboratory automation is the actual frontier for the increase of productivity and reduction of samples turnaround time (TAT), in turn used as a key indicator of laboratory performance. However, due to the statistical distribution of TAT values, classical parameters (mean, standard deviation, percentiles) fail to describe each single sample processing “story”. The driving idea of the present work is to assimilate the samples flow in an automation laboratory to the movement of molecules in solution by means of Dynamic Light Scattering Correlation Function analysis expansion.

OBJECTIVE

The aim of the approach is the increase of productivity and the reduction of laboratory process cycle times thus improving data quality level. The most widely known application of laboratory automation technology is robotics, based on many different automated laboratory instruments, devices (the most common being autosamplers), software algorithms and methodologies assembled together to form an unique production chain starting from the arrival of the biological sample in the lab to the output of clinical useful final results.

METHODS

TAT values from 10000 samples were used to build a correlation function. Through a time course, each sample perfectly correlates with its initial status (no results available) until its specific TAT value is reached and assumes a value of 1; after the TAT is reached (produced results) it no more correlates and its status value becomes 0. The generated correlation function is simply the normalized progressive timing sum of all analyzed samples status conditions at each specific time.

RESULTS

By correlation function analysis, several parameters to describe the general performance of the system as well as each individual sample status are derived and applied to monitor the efficiency of the automation chain in real time mode.

CONCLUSIONS

Our original approach to laboratory automation leads to the possibility of determining measurable criteria able to describe the entire system capacity to buffer and reduce problems both on the full performance or on spot samples, consequently developing a new tool to evaluate different or improved performing systems

To study astrophysical transit phenomena we follow an alternative strategy for getting high-cadence observations of the field. This can be achieved with our new Fly’s Eye Camera System that monitors the entire sky above 30◦ horizontal altitude. With this instrument one can observe all phenomena brighter than ∼ 15m in Sloan r-band (u’, g’,i’ and z’ filters are also available). If we stack together a few hour of images we canobserve ∼ 17 m faint sources. This small-sized instrument is designed for time-domain astronomy with its 150 sec cadence. Due to the hexapod-based motion control, the instrument can be installed anywhere without any modifications, it can accomplish sky tracking automatically. These parallel robots have 6 degrees of freedom (DoF), but since any kind of rotation can be done by using only 3 DoF, the tracking with hexapods is independent from the geographical coordinates. Even polar alignment is not required, because Fly’s Eye can calibrate itself based on its own observed data. The system is optimal for time-domain astronomy: detecting novae, supernovae, optical afterglows of gamma-ray bursts and other bright, fast transients, and, from the
observation database such data can be obtained - even from before the discovery of the transient event. In the future when the direction of the gravitational waves will be defined precisely we will be able to detect their first multiwaveband counterparts. In addition the Fly’s Eye will support the “Transient Astrophysical Objects” project which will use two new 80 cm robotic telescopes for follow-up observations of transients.

The current UK’s National Space and Security Policy states that the identification of potential on-orbit collisions and warning of re-entries over UK sovereign territory is of high importance, driving requirements for indigenous Space Situational Awareness (SSA) systems capable of delivering these products.
The UK’s Defence Science and Technology Laboratory (Dstl) is examining options for the creation of a distributed network of longitudinally distributed, low cost commercial–off-the-shelf electro-optical sensors to support survey work and catalogue maintenance. To effectively exploit this, a robust data handling system is required to autonomously detect satellite trails in a manner that can handle variable target intensities, periodicities and rates of apparent motion, as well as meteors and aircraft. Data captured during the United Kingdom/New Zealand Automated Transfer Vehicle-5 (ATV-5) deorbit observation trial have been employed to inform the development of a prototype processing pipeline for autonomous on-site processing. The approach taken employs pre-existing and documented tools such as Astrometry.NET and DAOPHOT from the astronomical community, together with image processing and orbit determination software developed in-house by Dstl. Some preliminary results from the automated analysis of data collected from wide angle sensors are described, together with an appraisal of the limitations of the proposed system and our plans for future development

Introdução: A incontinência urinária de esforço (IUE), definida por queixa de perda involuntária de urina após tosse, espirro ou esforço  físico, é a mais prevalente na população em geral. Objetivo: Verificar   alternativas à melhoria da IUE através da atuação da Fisioterapia  melhorando a qualidade de vida desses pacientes. Metodologia: Esta pesquisa se caracteriza por um estudo de caso que apresenta uma  análise qualitativa e descritiva. O caso a ser estudado envolve uma  mulher de 58 anos, o qual realizou 9 sessões de fisioterapia, duas  vezes por semana, com duração de 50 minutos cada sessão, na  Clínica  Escola de Fisioterapia da URI. A paciente foi submetida a uma   avaliação da qualidade de vida utilizando o questionário      denominado International Consultation on Incontinence Questionnaire  - Short Form (ICIQ-SF). Após, a intervenção fisioterapêutica utilizada  foi composta por exercícios de cinesioterapia (conscientização e série  de Kegel) com cones vaginais realizados em 12 séries, divididos em  fibras tipo I e II e eletroestimulação. Resultados: Observou-se  aumento da força da musculatura do assoalho pélvico (MAP), tanto da  musculatura superficial quanto da musculatura profunda e também   aumento  da resistência da mesma. Quanto ao questionário sobre a  qualidade de vida, não houve mudanças. Conclusão: A prática dos    exercícios foram essenciais para a reeducação e fortalecimento dos  músculos do assoalho pélvico.

Objetivos: este estudo teve o objetivo de identificar e conhecer a crença dos idosos em símbolos espirituais que expressam sua espiritualidade e religiosidade, utilizando-os em diferentes situações para vencer os obstáculos da idade, fortalecendo-os e proporcionando bem-estar físico, mental e espiritual. Sabe-se que o ser humano é um ser religioso e os símbolos sagrados são respeitados por representarem a existência de uma força superior acenando a possibilidade do homem conectar-se com o divino, ocupando um lugar de destaque na vida terrena. Materiais e métodos: este estudo foi observacional do tipo transversal, realizado na cidade de Chapecó (SC), no período de julho de 2008 a janeiro de 2009. Fez parte da amostra 2.160 pessoas de idades 20 a 39, de 40 a 59 e acima de 60 anos, implicando em 720 indivíduos entrevistados em cada faixa etária nas suas residências. Na conferência do banco de dados, optou-se pela análise descritiva univariada, com a obtenção das frequências simples e relativas para cada variável investigada, e os dados finais receberam tratamento estatístico utilizando-se o software SPSS 13.0 (Statistical Package to Social Sciences for Windows). Resultados: a partir dos resultados, observou-se que 68,5% dos pesquisados acreditam em símbolos espirituais. 47,3% apontam a Bíblia como símbolo mais reverenciado em que depositam sua crença e fé e 73,9% confirmam que os  símbolos os ajudam no enfrentamento das diferentes situações da vida cotidiana. Conclusão: frente aos achados, pode-se inferir que, com o aprofundamento do  envelhecimento, os idosos tornam-se mais espiritualizados e olham com mais serenidade para a vida ampliando a fé, aproximando-se de Deus, acreditando nos símbolos e forças espirituais, exercitando mais suas práticas religiosas (preces, orações, súplicas).

Introdução: a asma brônquica é uma doença inflamatória crônica das vias aéreas quese caracteriza por obstrução reversível espontaneamente ou com tratamento. A maiorprevalência é entre crianças, configurando assim um sério problema de saúde. Esse estudo teve como objetivos identificar quais as diferenças entre a forma do tórax, avaliar o padrão respiratório, avaliar a pressão expiratória e inspiratória máxima e ainda o pico defluxo expiratório. Material e métodos: a presente pesquisa caracteriza-se pelo método quantitativo, tendo uma amostra de 40 crianças entre 06 a 12 anos de idade, sendo 20 sem diagnóstico de asma brônquica (Grupo 1), e 20 com diagnóstico de asma brônquica(Grupo 2). Para a análise dos resultados foi utilizado a média, desvio padrão e Teste t deStudent, apresentados através de tabelas descritivas. Resultados e discussão: podeseconcluir que em algumas medidas e análises o grupo de crianças asmáticas atingiuresultados inferiores em relação ao grupo de crianças saudáveis. O asmático em funçãodas características da doença apresenta um aumento da resistência ao fluxo aéreo,aprisionamento de ar e hiperinsuflação pulmonar, o que levam a alterações mecânicas nadinâmica tóraco-abdominal e à desvantagem muscular. Conclusão: a avaliação adequadada mecânica respiratória, juntamente com tratamento da asma na infância são importantesfatores para a prevenção secundária de redução da função pulmonar e de doença pulmonarcrônica na vida adulta. São necessários mais estudos e com uma amostra maior para que sejapossível estabelecer um consenso a esse respeito, principalmente estudos com crianças, emque verificamos que o número de pesquisas com este público é menor, a fim de produzirmaiores conhecimentos a este assunto.
