Prompt Recognition of Left Ventricular Free-Wall Rupture Aided by the Use of Contrast Echocardiography
Authors: Okabe Toshimasa , Julien Howard M. , Kaliyadan Antony G. , Siu Henry , Marhefka Gregary D.
Published: October 2015

In the modern period of reperfusion, left ventricular free-wall rupture occurs in less than 1% of myocardial infarctions. Typically, acute left ventricular free-wall rupture leads to sudden death from immediate cardiac tamponade. We present the case of a 59-year-old woman who sustained a posterior-wall myocardial infarction and subsequent cardiac arrest with pulseless electrical activity. A bedside transthoracic echocardiogram showed pericardial effusion with cardiac tamponade. Emergency pericardiocentesis yielded 500 mL of blood, and spontaneous circulation returned. Contrast-enhanced echocardiograms revealed inferolateral akinesis and a new, small myocardial slit with systolic extrusion of contrast medium, consistent with left ventricular free-wall rupture. During immediate open-heart surgery, a small hole in an area of necrotic tissue was discovered and repaired. This case highlights the usefulness of bedside contrast-enhanced echocardiography in confirming acute left ventricular free-wall rupture and enabling rapid surgical treatment.
Successful Prasugrel Therapy for Recurrent Left Main Stent Thrombosis in a Clopidogrel Hyporesponder
Authors: Kim Yi-Sik , Lee Sang-Rok
Published: October 2015

Stent thrombosis is a life-threatening sequela of drug-eluting stent implantation. Dual antiplatelet therapy with aspirin and thienopyridine is typically used to prevent this catastrophic event. In terms of stent thrombosis, the major concern is the variable response of patients to clopidogrel, and this has raised interest in new antiplatelet agents. We present the case of a 64-year-old woman whom we successfully treated with prasugrel after she had repeated episodes of stent thrombosis caused by a poor response to clopidogrel. This case highlights the potential role of new antiplatelet agents for patients who are undergoing drug-eluting stent implantation.
Acute Respiratory Failure Induced by Magnesium Replacement in a 62-Year-Old Woman with Myasthenia Gravis
Authors: Singh Paramveer , Idowu Olakunle , Malik Imrana , Nates Joseph L.
Published: October 2015

Magnesium is known to act at the neuromuscular junction by inhibiting the presynaptic release of acetylcholine and desensitizing the postsynaptic membrane. Because of these effects, magnesium has been postulated to potentiate neuromuscular weakness. We describe the case of a 62-year-old woman with myasthenia gravis and a metastatic thymoma who was admitted to our intensive care unit for management of a myasthenic crisis. The patient's neuromuscular weakness worsened in association with standard intravenous magnesium replacement, and the exacerbated respiratory failure necessitated intubation, mechanical ventilation, and an extended stay in the intensive care unit. The effect of magnesium replacement on myasthenia gravis patients has not been well documented, and we present this case to increase awareness and stimulate research. In addition, we discuss the relevant medical literature.

Published: October 2015

Some existence results for a parametric Dirichlet problem defined on the Sierpiński fractal are proved. More precisely, a critical point result for differentiable functionals is
exploited in order to prove the existence of a well-determined open
interval of positive eigenvalues for which the problem admits at
least one non-trivial weak solution.

Published: October 2015

Let Ω be a bounded open interval, letp>1${p>1}$andγ>0${\gamma>0}$, and letm:Ω→ℝ${m:\Omega\rightarrow\mathbb{R}}$be a function that may change sign in Ω. In this article we study the existence and nonexistence of positive solutions for one-dimensional singular problems of the form-(|u′|p-2⁢u′)′=m⁢(x)⁢u-γ${-(|u^{\prime}|^{p-2}u^{\prime})^{\prime}=m(x)u^{-\gamma}}$in Ω,u=0${u=0}$on∂⁡Ω${\partial\Omega}$. As a consequence we also derive existence results for other related nonlinearities.

Published: October 2015

: Serum alkaline phosphatase (ALP) plays a critical role in the diagnosis of various diseases, and the establishment of relevant, reliable reference intervals (RI) is key to avoiding misdiagnoses. In 2011, IFCC published the new reference measurement procedure (RMP) for the determination of serum ALP in which one of the main modifications was the measuring temperature of the assay. Here, the new RMP was used to help establish RIs for serum ALP concentrations in healthy Chinese Han.

Volunteer individuals in Guangdong province, China (n=1622) were screened by questionnaire and laboratory testing for eligibility as a reference. Blood (20 mL) was collected and samples were measured by the Roche Modular system using the new RMP for the serum ALP compatible method. Partitioning of values by gender and/or age was evaluated with a standard normal deviate test after removing outliers. A simple non-parametric method for a two-sided 95% distribution of reference values was calculated.

Serum ALP concentrations were obtained from the cohort of eligible reference individuals (n=658). The RI for serum ALP in males age 18–79 years was 48–131 U/L. Females were partitioned into two age groups based on statistical analysis, 18–49 years and 50–79 years, and the RIs derived were 40–106 U/L and 57–159 U/L, respectively.

RIs for serum ALP for Chinese Han individuals in between the ages of 18 and 79 years were determined and required partitioning due to the higher ALP values of females age 50–79 years.

Authors: Tagliapietra Silvia , Orio Laura , Palmisano Giovanni , Penoni Andrea , Cravotto Giancarlo
Published: October 2015

There is currently a significant increase in the use of glycerol as a renewable solvent for catalytic reactions. Glycerol has often been the solvent of choice in both homogeneous and heterogeneous catalyses, despite its high viscosity at ambient temperature and the low solubility of highly hydrophobic reagents found in glycerol. Its biodegradability and non-toxicity have led to reports of improved reaction performance and selectivity, as well as easier product separation and effective catalyst recycling. All relevant advances in this emerging field of “green” catalysis are thoroughly reviewed below.

Small Two-Bar Specimen Creep Testing of Grade P91 Steel at 650°C
Authors: Ali Balhassn S. M. , Hyde Tom H. , Sun Wei
Published: October 2015

Commonly used small creep specimen types, such as ring and impression creep specimens, are capable of providing minimum creep strain rate data from small volumes of material. However, these test types are unable to provide the creep rupture data. In this paper the recently developed two-bar specimen type, which can be used to obtain minimum creep strain rate and creep rupture creep data from small volumes of material, is described. Conversion relationships are used to convert (i) the applied load to the equivalent uniaxial stress, and (ii) the load line deformation rate to the equivalent uniaxial creep strain rate. The effects of the specimen dimension ratios on the conversion factors are also discussed in this paper. This paper also shows comparisons between two-bar specimen creep test data and the corresponding uniaxial creep test data, for grade P91 steel at 650°C.
Identification of irradiated dried fruits using EPR spectroscopy
Authors: Guzik Grzegorz P. , Stachowicz Wacław , Michalik Jacek
Published: September 2015

The dominating carbohydrates in fruits are monosaccharides like fructose, glucose, sorbose and mannose. In dehydrated fruits, concentration of monosaccharides is higher than in fresh fruits resulting in the formation of sugar crystallites. In most of dried fruits, crystalline fructose, and glucose dominate and appear in proportion near to 1:1. Irradiation of dried fruits stimulates radiation chemical processes resulting in the formation of new chemical products and free radicals giving rise to multicomponent EPR signal which can be detected for a long period of time. For that reason, it is used as a marker for the detection of radiation treatment of dried fruits. It has been found that EPR spectra recorded in dried banana, pineapple, papaya, and fig samples resemble the EPR spectrum obtained by computer addition of fructose and glucose spectra taken in proportion 1:1. The decay of radiation induced EPR signals proceeds in dried fruits fast during the first month of observation and becomes much slower and almost negligible after prolonged storage. However, it remains intense enough for EPR detection even one year after processing. The radiation induced EPR signal is easily detected in dried fruits exposed to 0.5 kGy of gamma rays. Thus, the EPR method of the detection of irradiated fruits can be used for the control of dried fruits undergoing quarantine treatment with 200-300 Gy of ionizing radiation.

Published: September 2015

Medieval Central Europe coins - the Saxon coins, also called as the Otto and Adelheid denarii, as well as the Polish ones, the Władysław Herman and Bolesław Śmiały coins - were examined to determine their provenance and dating. Their attribution and chronology often constitute a serious problem for historians and numismatists. For hundreds of years, coins were in uncontrolled conditions and in variable environment. Destructed and inhomogeneous surface were the effect of corrosion processes. Electron microscopy with energy dispersive X-ray analysis (scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS)), X-ray fluorescence (XRF) analysis (energy dispersive X-ray fluorescence (EDXRF) and total reflection X-ray fluorescence (TXRF)), and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) were applied. The results of these investigations are significant for our knowledge of the history of Central European coinage, especially of Polish coinage

Regional topology and approximative solutions of difference and differential equations
Authors: Migda Janusz
Published: September 2015

We introduce a topology, which we call the regional topology, on the space of all real functions on a given locally compact metric space. Next we obtain new versions of Schauder’s fixed point theorem and Ascoli’s theorem. We use these theorems and the properties of the iterated remainder operator to establish conditions under which there exist solutions, with prescribed asymptotic behaviour, of some difference and differential equations.
Nonautonomous Solitons for the Coupled Variable-Coefficient Cubic-Quintic Nonlinear Schrödinger Equations with External Potentials in the Non-Kerr Fibre
Authors: Mao Bing-Qing , Gao Yi-Tian , Feng Yu-Jie , Yu Xin
Published: October 2015

Variable-coefficient nonlinear Schrödinger (NLS)-type models are used to describe certain phenomena in plasma physics, nonlinear optics, arterial mechanics, and Bose–Einstein condensation. In this article, the coupled variable-coefficient cubic-quintic NLS equations with external potentials in the non-Kerr fibre are investigated. Via symbolic computation, similarity transformations and relevant constraints on the coefficient functions are obtained. Based on those transformations, such equations are transformed into the coupled cubic-quintic NLS equations with constant coefficients. Nonautonomous soliton solutions are derived, and propagation and interaction of the nonautonomous solitons in the non-Kerr fibre are investigated analytically and graphically. Those soliton solutions are related to the group velocity dispersionr(x) and external potentialsh1(x) andh2(x,t). With the different choices ofr(x), parabolic, cubic, and periodically oscillating solitons are obtained; with the different choices ofh2(x,t), we can see the dromion-like structures and nonautonomous solitons with smooth step-like oscillator frequency profiles, to name a few.

Published: October 2015

Currently, silicon and germanium, the most common materials in the production of discrete semiconductor devices and integrated circuits, do not always meet all the requirements to the sensing elements of mechanical quantities sensors. Therefore, it is logical to research the properties of other semiconductor materials that could be used as sensing elements in such sensors. A3B5 semiconductor compounds seem promising for such purpose. Effect of hydrostatic pressure up to 5000 bar on the resistance of n-type antimonide gallium whiskers doped by Se or Te was studied. Coefficient of hydrostatic pressure for this crystals was determined, it equals Kh = (16,5—20,0)•10–5 bar–1 at 20°N. Temperature dependence of resistance and coefficient Kh for this crystals in the temperature range ±60°N was studied. Design of the developed hydrostatic pressure sensor based on GaSb whiskers and its characteristics are presented. The possibility to decrease the temperature dependence of sensitive element resistance by mounting GaSb whiskers on the substrates fabricated from materials with different temperature coefficient of expansion was examined. It was shown that mounting of GaSb crystals on Cu substrate gives the optimal result, in this case the temperature coefficient decrease to 0,05%•°N–1, that leads to decrease of output temperature dependence. The main advantages of developed pressure sensor are: the simplified design in comparison with pressure sensors with strain gauges mounted on spring elements; the high sensitivity to pressure that is constant in the wide pressure range; the improvement of sensors metrological characteristics owing to hysteresis absence. The possible application fields of developed sensors are measuring of high and extremely high pressure, chemical and oil industries, measuring of pressure in oil bore-holes, investigation of explosive processes.
Thermal monitoring as a method for estimation of technical state of digital devices
Authors: Lavrich Yu. N.
Published: October 2015

Requirements to the reliability level of modern element base are so high that traditional methods of assessing the technical condition of electronics become ineffective, the modern theory of reliability has almost no practical applications [1], and reliability index does not reflect the true state of an electronic device due to an insufficient amount of information received during testing of electronic devices.
The majority of modern electronics are limitedly easy-to-test. They are equipped with small number of tools for direct measurement that leads to a delayed troubleshooting and the inability to take measures efficiently.
Despite the fact that new generations of electronics use modern components and new design technologies, their performance is still defined by two states — serviceability or failure, and the failure still happens unexpectedly. We may note, that failure is an uncontrolled result of an irreversible degradation process, taking place in time and having appropriate time parameters, but it's not the critical act.
Research of various structural and hierarchical levels of functional units of digital electronics show that temperature control can be used for automatic condition monitoring of such devices in real time. As a generalized control parameter, it is advisable to use the temperature of the case of the element, and the case itself — as a generalized point.
Getting on Good Terms
Authors: Clark Rob , Cason Trent
Published: October 2015

For much of the twentieth century, less developed countries endured deteriorating terms of trade relative to more advanced nations. During that time, a number of explanations emerged to help explain the “unequal exchange” that occurred between rich and poor countries. We revisit these ideas in light of recent data showing more favorable trade terms for a large number of countries in the developing world. Using panel data covering 132 countries during the 1990–2012 period, our analysis considers the importance of trade composition, productive capacity, labor power, foreign capital, factor endowments, and macroeconomic conditions in affecting a country's net barter terms of trade. In addition, we introduce a measure of trade coreness to this field of work, which indicates the relative bargaining power that countries possess during exchange. Our results show that changes in the terms of trade can be attributed to several factors. Most notably, our findings suggest that foreign capital penetration leads to deteriorating terms of trade via its impact on labor conditions, while countries occupying more core-like positions in the international trade network have come to experience more favorable trade terms.

Objective

Pituitary adenomas (PA) are among the most common human neoplasms. To describe the epidemiology and assess the disease burden of clinically significant PAs, population-based studies are needed. Iceland has a small well-defined population. The aim of this study is to describe the epidemiology of PAs in Iceland over an expanded period of time.

Design

This is a retrospective observational study, including all PAs diagnosed in Iceland from 1955 to 2012.

Methods

Extensive clinical information was gathered in a database. Prevalence rates for all PA subtypes were calculated along with standardized incidence rates (SIR). Sex ratios and relationships with adenoma size, age, and symptoms were assessed.

Results

We identified 471 individuals: 190 men and 281 women. Total prevalence in 2012 was 115.57/100 000, prolactinomas were most prevalent (54.37/100 000) followed by non-functioning adenomas (NFPAs) (42.32/100 000). Throughout the period, NFPAs were most common (43.0%) followed by prolactinomas (39.9%) and 11.3% had acromegaly and 5.7% Cushing's disease. Women are diagnosed younger with smaller adenomas. Total SIR has increased significantly and is now 5.8/100 000 per year.

Conclusion

In this nationwide study spanning six decades, we have confirmed PAs rising prevalence and incidence rates noted in recent studies. We demonstrated higher overall prevalence and incidence rates than ever previously recorded with an increasing predominance of NFPAs, which is not explained by incidental findings alone. There is a relationship with the introduction of imaging modalities, but the vast majority of patients are symptomatic at diagnosis. This underlines the importance of increased awareness, education, and appropriate allocation of resources for this growing group of patients.

Authors: Patrick Stephen W. , Burke James F. , Biel Terry J. , Auger Katherine A. , Goyal Neera K. , Cooper William O.
Published: October 2015

OBJECTIVE:

Neonatal abstinence syndrome (NAS) is a postnatal drug withdrawal syndrome that may last for months. Our objective was to determine if infants with NAS are at increased risk for hospital readmission compared with uncomplicated term and late preterm newborns.

METHODS:

In this longitudinal retrospective cohort study, administrative data were used for all births from 2006 to 2009 in the New York State Inpatient Database. We identified infants with NAS, born late preterm or uncomplicated term, as independent groups using diagnostic codes and determined readmission rates. We fit a multivariable logistic regression model with 30-day readmission after discharge as the outcome and infant characteristics, clinical morbidities, insurance type, and length of birth hospitalization as predictors.

RESULTS:

From 2006 to 2009 in New York State, 700 613 infants were classified as uncomplicated term, 51 748 were born late preterm, and 1643 infants were diagnosed with NAS. After adjusting for confounders, infants with NAS (odds ratio [OR] 2.49, 95% confidence interval [CI] 1.75–3.55) were more likely than uncomplicated term infants to be readmitted within 30 days of birth hospitalizations. The risk of readmission was similar to late preterm infants (OR 2.26, 95% CI 2.09–2.45). Length of birth hospitalization in days was inversely related to odds of being readmitted within 30 days of birth hospitalization (OR 0.94 95% CI 0.92–0.96).

CONCLUSIONS:

When compared with uncomplicated term infants, infants diagnosed with NAS were more than twice as likely to be readmitted to the hospital. Future research and state-level policies should investigate means to mitigate risk of hospital readmission for infants with NAS.

Published: October 2015

Purpose: is study of adaptation mechanisms of 400 meter’ hurdles-runners to intensive physical loads. Material: in the research 13 - 400 meters’ hurdles-runners and 13 - 400 meters’ runners participated. Results: it was found that physiological cost of sportsmen’s special workability has fragmentary character. We presented results of physiological and bio-chemical adaptation mechanisms to dozed work. The received results have no confident distinctions and can not objectively characterize mechanisms of sportsmen’s special workability. We did not detect definite differences in indicators of mechanisms, ensuring sportsmen’s special workability under dozed loads. We found, that level of anaerobic glycolysis is an objective criterion of 400 meter’ hurdles-runners’ special workability. It was shown that for determination of functional potentials for such kind of functioning it is necessary to apply special loads. Conclusions: the received results deepen information about mechanisms of adaptation to specific competition functioning. Correct approaches to processing and analysis of the research’s results permit to more specifically determine sportsmen’s functional potentials in different kinds of competition functioning.
Microstructure and Crystallographic Texture Development of Microalloyed Twinning Induced Plasticity (TWIP) Steels Under Uniaxial Hot-Tensile Conditions
Authors: Salas-Reyes A.E. , Mejía I. , Cabrera J.M.
Published: October 2015

Nowadays, there are limited referenced data on the hot deformation of twinning induced plasticity (TWIP) steels, particularly on the crystallographic preferred orientation (crystallographic texture). It is well know that texture is one of the most important factors affecting sheet metal forming performance. The aim of this research work is to determine the influence of microalloying elements on the microstructure and texture of high-Mn austenitic TWIP steels deformed under uniaxial hot-tensile conditions. For this purpose, one non-microalloyed and other single microalloyed with Ti, V and Mo TWIP steels were melted in an induction furnace and cast into metal and sand molds. Samples with average austenitic grain size between 400 and 2000 µm were deformed in the temperature range between 800 and 900 °C at a constant true strain rate of 10-3 s-1. The evolution of the microstructure and texture near to the fracture tip were characterized using electron back-scattering diffraction (EBSD) technique. The results show that the TWIP steels microalloyed with V and Mo and the non-microalloyed one, solidified in metal mold, exhibit dynamically recrystallized grains oriented in the [012] preferential direction, which was corroborated by local misorientation measurements, indicating low dislocation density. On the other hand, most TWIP steels solidified in sand molds do not show dynamically recrystallized grains, having the largest austenitic grains oriented in the [001]/[101] preferred directions. In general, weak textural Cube {001}<100> combined with <111> fiber, namely γ-fiber, spread from E {111}<110> to Y {111}<112> as major texture components were detected.
Sufism Without Boundaries
Authors: Alam Sarwar
Published: October 2015

Most scholars believe that the majority of the population of Bangladesh embraced Islam through the influence of the Sufis (mystics, holy men). A large majority of Bangladeshi Muslims perceives Sufis as sources of their spiritual wisdom and guidance, viewing Sufi khanqahs [hospices] and dargahs [mausoleums] to be the nerve centers of Muslim society. It has been argued that the greatest achievement of the Sufis of Bengal is the “growth of cordiality and unity between the Hindus and the Muslims.” Yet, Sufism is a contested phenomenon in Bangladesh. Islamic reform movements in the nineteenth and twentieth centuries preached against some Sufi rituals and practices, and Sufism as a whole. This article analyzes how the concept of “Bangalee Nationalism” emerges, among others, from various Sufi ideologies that recognize the authenticity of another’s faith. This article will also analyze how these traditions have hitherto been engaged in establishing a pluralistic society as well as in developing a culture of tolerance and interfaith dialogue.
Challenge of Religious Pluralism in Malaysia with Special Reference to the Sufi Thought of Ustaz Ashaari Muhammad
Authors: Hamid Ahmad Fauzi Abdul
Published: October 2015

Ustaz Ashaari Muhammad (1937-2010) was a sufi leader best remembered for the controversies surrounding his eschatological teachings which led to the Malaysian government’s banning of his organization, Darul Arqam, in 1994. Loved by admirers but reviled by the state, Ashaari’s influence cut across ethnicity, nationality and religion. While the transnational dimensions of Ashaari’s activities were well-known, aspects of ethno-religious pluralism in his thought, as conveyed in a multitude of written works published independently, have mostly escaped the attention of analysts and casual observers alike. With contemporary Malaysian Islam being invariably understood via ethnically slanted lenses, it would not have occurred to most people that a Malay-Muslim religious personality would actually subscribe to pluralistic conceptions of society which are liable to be interpreted as undermining conceptions of Malay-Muslim hegemony dearly held by the ruling establishment of the day. This chapter seeks to bring to the fore features of Ashaari’s thought which exemplifies integration between Sufism and political realities as conditioned by nation state-defined categories.

This paper aims at comparing national identity situations in Moldova and the self-proclaimed Transnistrian state (Pridnestrovie). Moldovan identity is torn and takes at least five forms: (1) Moldovan ethnonational identity as a regional variation of the Romanian one; (2) specifically Moldovan ethnonational identity; (3) post-Soviet amorphous ‘non-identity’; (4) specific identities of ethnic minorities (identification of the Ukrainians with Ukraine, Russians with Russia, etc.); (5) marginal identities of the titular ethnic group. None of these identity projects is directed towards consolidating the Moldovan civil nation, including ethnic minorities (roughly making 22 % of the population). Moreover, there is an identity split within the titular ethnic group, more complex than a dilemma of Romanianism / Moldovanism. Moldovanism has at least two versions (ethicized and integrative), not mentioning marginalized identities (such as Romanian-speaking Orthodox fundamentalists objecting eurointegration). Transnistrian identity, to the contrary, is firm and consolidated, although it consists of seemingly incompatible parts (pre-Soviet, Soviet and post-Soviet). It is a civil identity based on ideology, not on ethnicity. This ideology is also mosaic and cannot be reduced to ‘neo-Communism’ or Russian nationalism. Thus, Transnistrian national project is open for all post-Soviet ethnic groups. Rapid reunification of the two banks seems impossible because their national projects have not just different contents, but different structures. Moldova should first decide on its vision of the national project and then build its policy towards Pridnestrovie and the EU on this ground. Without it, the conflict cannot be resolved in the foreseeable future.

The article provides an overview of the language problems in the Republic of Kazakhstan. Social and theoretical deconstruction of the Soviet ethno-cultural monolith has led to changes in socio-psychological self-identification that reflect previously hidden differences in identity and language usage. The focus of the article is on the language knowledge, attitudes and the ethnolinguistic vitality of four ethnic minority group of Kazakhstan: Russians, Ukrainians, Poles, and Koreans. The research findings indicate that the level of knowledge of Russian is high amongst Russians while the other groups studied have low knowledge of heritage language and have mainly shifted to Russian. The knowledge and the use of Kazakh language is low amongst all minorities studied, while the attitudes towards learning Kazakh are generally positive. The analysis of the ethnolinguistic vitality showed that the Russians have high ethnolinguistic vitality with a weak level of ethnocentrism while Ukrainians and Poles have low ethnolinguistic vitality indicating a medium danger of assimilation. Koreans have the lowest ethnolinguistic vitality indicating a strong danger of assimilation.

Russian-speaking migrant communities in Germany and Norway share a large part of a common history during the time of the Soviet Union, and each community has developed their unique ways of interaction in and with the accepting society. The article focuses on the main areas for communication between Russian-speaking migrants in Germany and Norway, as well as the wish to maintain contact with ones’ home country. As the question of maintaining ones identity as well as the vitality of these communities is strongly linked to its members’ wish to maintain their common language, these aspects were covered in particular through the study. The article uses a combined research method consisting of a quantitative and qualitative part. The findings indicate that while the groups are different from each other, particularly in their demographic composition, distribution and communication patterns, they do possess some similarities for example having common elements defining and retaining their cultural heritage and approaches towards maintaining the Russian language.

O isolamento térmico é empregado na proteção de superfícies aquecidas ou resfriadas através de materiais de baixa condutividade térmica, onde as espumas rígidas de poliuretano (PUR) são as mais utilizadas. O rejeito de vidro não é aproveitável pela indústria recicladora, por isto algumas pesquisas buscam um aproveitamento desse resíduo vítreo aplicando-o como reforço em materiais. Neste trabalho foram desenvolvidos compósitos de PUR carregadas com pó de vidro (PV) refinado objetivando uma comparação com o PUR puro e sua adequação como isolante térmico. O PV foi triturado e moído, obtendo-se duas granulometrias diferentes, as quais foram caracterizadas por Análise de Granulometria a Laser, DRX e FRX. Os corpos-de-prova de PUR+PV foram produzidos aplicando-se percentuais mássicos de PV a 5, 10 e 20, cujas características foram analisadas através de ensaios de condutividade térmica, massa específica e resistência à compressão. Os resultados demonstraram que as propriedades dos compósitos de PUR são influenciadas pelos percentuais de PV adicionados na matriz de PUR. Assim, constatou-se que a resistência à compressão (exceto o PV20-100) e a massa específica dos compósitos PUR+PV foi superior à do PUR puro. A condutividade térmica dos compósitos PUR+PV permaneceu numa faixa de 0,035 a 0,045 W/m-K, o que pode sugerir que a inclusão do PV não afetou significativamente as propriedades termofísicas, quando comparadas às do PUR puro (0,040 W/m-K). A partir destas análises, a aplicabilidade do rejeito vítreo contribuiu como reforço do PUR e a sua função de isolação térmica não foi reduzida. Isto possibilita maior economia e preservação ambiental.

Este trabalho tem como objetivo o estudo do balancim, um dispositivo da suspensão do veículo Fórmula SAE que recebe os esforços oriundos do movimento de rolagem do veículo e os transmite para a estrutura do chassi de uma forma minimizada por uma relação de momento e suavizada pelo conjunto mola – amortecedor. Realiza-se uma revisão sobre parâmetros usados em dinâmica veicular e uma análise geométrica das forças e dos esforços provocados por tais. Em seguida, faz-se a análise pelo método dos elementos finitos, que utiliza a teoria de discretização de sistemas e analisa a resistência do componente baseado na energia de distorção, determinando a tensão máxima sofrida pelo componente e a região de maior solicitação e o fator de segurança para um carregamento estático

O objetivo deste trabalho é identificar os aspectos da satisfação e motivação dos funcionários técnicos administrativos do IFRN Campus Natal Central. Pois se considerando a importância social do setor publico no país, deve-se promover estudos que visem avaliar os aspectos motivacionais que reforçem a satisfação do funcionário, visto que a qualidade no atendimento ao público externo tende a estar ligado à satisfação desse publico para com a organização. Dessa forma, foi realizado um estudo de caráter exploratório e descritivo, do tipo estudo de caso e abordagem quantitativa. A população desta pesquisa foi formada pelos servidores técnico-administrativos do IFRN Campus Natal-Central, no qual se coletaram 136 questionários, atendendo ao critério de amostra probabilística. Os resultados apresentaram que as pessoas se sentem fortemente motivadas, evidenciando que a maioria deve gostar do trabalho que desenvolve. Esse mesmo resultado se confirma no nível de satisfação com o trabalho Isso demostra que a maioria dos servidores trabalham com o que gostam, promovendo uma forte relação e sentindo-se satisfeitos como o seu trabalho. A analise de Cluster demonstrou que pode ser possível diferenciar dois agrupamentos, que apresentam nível de satisfação e motivação diferenciados. Conclui-se que os funcionários menos motivados são os que possuem mais tempo de serviço e que percebem o seu trabalho com menor nível de importância. Essa informação sugere uma urgência em destacar a importância do sentido do trabalho para esses profissionais.

Cerca de 98% do território do Rio Grande do Norte estão incluídos nas chamadas Áreas Susceptíveis à Desertificação do Brasil. Na região do Baixo-Açu, o desmatamento sistemático da mata nativa para atender às necessidades do polo ceramista e de outras pequenas indústrias locais tem intensificado o grave quadro de devastação ambiental da região. Este estudo examinou a viabilidade econômico-financeira da produção comercial de briquetes como forma de suprir parte da demanda por lenha e carvão vegetal, mitigando assim os efeitos antrópicos sobre o bioma caatinga. Os briquetes seriam compostos  de resíduos da produção de cera de carnaúba e  de capim-elefante plantado exclusivamente para fins energéticos nas áreas irrigáveis da região. As estimativas de custos de instalação e manutenção da fábrica foram feitas tendo como parâmetros os custos de instalação de uma fábrica-escola em construção no Campus Ipanguaçu do IFRN e os custos de produção de uma fábrica idêntica a esta, em operação há cinco anos, no Estado do Paraná. Os dados foram sistematizados em planilhas do software Make Money, usado na avaliação da viabilidade econômica a partir de aferidores como Valor Presente Líquido, Payback e Taxa Interna de Retorno. Os resultados comprovaram que a produção de biocombustíveis sólidos adensados é viável no Baixo-Açu e pode contribuir de maneira efetiva para a recomposição da mata nativa, além de gerar ocupação e renda para os moradores da região.
PRECIFICAÇÃO DA ENERGIA DISPONÍVEL NO BRIQUETE DE CARNAÚBA E CAPIM-ELEFANTE E NA LENHA DO SEMIÁRIDO POTIGUAR

Um dos maiores entraves para a consolidação do mercado para briquetes é o mito de que esses biocombustíveis são sempre mais caros do que a lenha advinda do puro extrativismo.  Através da análise comparativa do preço da energia disponível para queima em uma tonelada de lenha e briquete misto de palha de carnaúba e capim-elefante, este estudo comprovou que, dependendo do teor de umidade da lenha, o rendimento do briquete é superior em metade das 60 simulações feitas com três tipos de espécies vegetais do semiárido do Rio Grande do Norte.   A análise se baseou no cálculo do Poder Calorífico Útil de cada uma das biomassas analisadas e nos preços das respectivas toneladas
