Influence of high compression ratio and excess air ratio on performance and emissions of natural gas fuelled spark ignition engine
Authors: Sremec Mario , Bozic Mladen , Vucetic Ante , Kozarac Darko
Published: July 2018

Compressed natural gas is in automotive industry recognized as one of the ?cleanest? fossil fuels which can be used in internal combustion engines with a number of benefits. Since natural gas has much higher octane rating than gasoline it is expected that higher compression ratios can be used. The goal of the research is to determine the change of performance of spark ignited engine with the increase of compression ratio to values similar to compression ignited engine while keeping the exhaust emissions on the acceptable level and avoiding knock combustion. Measurements are performed at compression ratios 12, 16, and 18 at three different values of air excess ratio. Methane with known composition from a pressure cylinder is used instead of natural gas and the results are comprised of indicating results (in-cylinder and intake pressure in a crank angle space), emissions, temperatures, and mass-flows on various intake and exhaust positions. Analysis of results shows high influence of compression ratio and excess air ratio on combustion, performance, and exhaust gas emissions.

Published: July 2018

The steady boundary-layer flow of a nanofluid past a moving semi-infinite flat plate in a uniform free stream in the presence of second order slip is studied using a second order slip flow model. The governing PDE are transformed into non-linear ODE by using appropriate similarity transformations, which are then solved numerically using bvp4c solver for different values of selected parameters. We found that the solutions existed for dual in a certain range of velocity ratio parameter. Therefore, a stability analysis has been analyzed to show which solutions are stable. The effects of velocity ratio parameter, Lewis number, Prandtl number, Brownian motion parameter, thermopherosis parameter, mass suction, first order slip parameter, and second order slip parameter on the skin friction coefficient, heat transfer coefficient, dimensionless velocity, temperature as well as nanoparticle volume fraction profiles are figured out graphically and discussed. These results reveals that the slip parameters expand the range of the solutions obtained. The increment of slip parameters lead to decrease the skin friction coefficient while increase the heat transfer coefficient. In addition, the value of Lewis nmber, Prandtl number, Brownian motion parameter, and thermopherosis parameter are significantly affected the heat transfer coefficient. Lastly, the first solution is stable and physically relevant, while the second solution is not.

Authors: Lee Hye Seung (Grace) , Nagy Albert L. , Zimmerman Aleksandra B.
Published: July 2018

This paper examines the demand- and supply-side factors associated with audit partner selection and assignment in the United States. First, we examine whether audit partner gender and experience are associated with board and management gender and experience. Second, we investigate whether engagement audit quality varies with audit partner gender and experience, controlling for selection effects. The results indicate that companies with more gender-diverse boards of directors and top management teams are more likely to have a female lead audit partner. In addition, the experience of the client's board is positively associated with the experience of the lead audit partner. In terms of audit quality, we find that higher audit fees are positively associated with female and more experienced audit partners. Our results shed light on the important role that partner characteristics play in the demand and supply sides of audit quality.
Executive Stock Ownership Guidelines and Debtholder Wealth
Authors: Kang Jun-Koo , Xu Limin
Published: July 2018

We examine how the adoption of executive stock ownership guidelines affects debtholder wealth. We find that guideline adoption is associated with lower loan spreads, fewer collateral requirements, and fewer other restrictive covenants. The results are robust to using an instrumental variables approach. We further find that guideline adoption has a negative effect on bond yield spreads and that after the adoption, firms' risk-taking incentives are lower. These results suggest that guideline adoption benefits debtholders by lowering agency costs of debt. However, we also find that adoption of ownership guidelines is associated with a significant increase in stock prices, and that firms are more likely to increase financial reporting quality in the post-adoption period, indicating that guideline adoption incentivizes managers to improve firm fundamentals, benefiting both shareholders and debtholders.

Authors: AKKÖSE Ahmet
Published: July 2018

In this study, glass transition temperatures (Tg) as well as
ice crystallization and melting temperatures and enthalpy values were
determined by using Differential Scanning Calorimetry (DSC) for chicken breast
meat samples blended with different levels (2, 4, and 8%) of xanthan gum, κ-carrageenan
and gum arabic. The water activity (aw) values, moisture contents
and unfreezable water fractions of the samples were also analyzed. While the
moisture contents decreased and unfreezable moisture fractions increased, the aw
values of the samples unchanged by addition of the biopolymers. The ice
crystallization enthalpies and melting temperatures and enthalpy values
decreased with increased levels of biopolymer additions. Tg value of
the chicken breast meat was detected as -17.08±0.04°C
(midpoint). It was observed that Tg values of the samples significantly
affected by the biopolymer addition (P<0.01) and increased for the samples
including 4% and %8 xanthan gum and 8% κ-carrageenan.
Reduction of Tissue Maceration in Potatoes by Rose Essential Oil
Authors: DOĞUŞ SİVRİ Emine , ULUSOY Seyhan
Published: July 2018

Erwinia carotovora is a phytopathogen which causes soft-rot disease in a wide
variety of economically important plants. E. carotovora is known to produce a range of exoenzymes
that enhance its ability to damage the host tissue and cause disease. A cell to
cell communication mechanism called quorum sensing which is mediated by small
signalling molecules regulates exoenzymes (cellulase, pectinase and
protease) and carbapenem production
in E. carotovora. Thus the
exploration of new strategies to manipulate this communication pathway for the
prevention of E. carotovora
infections is valuable. In this study, the inhibitory effects of the rose,
orange, lavender, clove, cinnamon, black pepper and cumin oils on
the production of the exoenzymes (cellulase, pectinase and protease) and
carbapenem in the Erwinia carotovora subsp.
carotovora ATCC 39048 were investigated. And potato tissue maceration was also
tested in the presence of oils. Rose and lavender essential
oils markedly inhibited the production of pectinases by 38.7 and 9.7%, cellulases by 36.6
and 31.7% and proteases by 29 and 16.1%, carbapenem by 61.9 and 54%, and maceration of potatoes by 61.4
and 30.7% in the E. carotovora
respectively without affecting the growth of
cells. Although
several studies have reported antibacterial effects of rose and lavender essential oils, there is no report
describing their antivirulence potential. To the best of our knowledge, this is
the first report on the rose and lavender
essential oils with potential antivirulence components against soft rot caused by E. carotovora.

Published: July 2018

In parallel with the world population growth, the decrease in food sources, caused by global climate change, unplanned urbanization, unplanned industrialization and reduction of agricultural land etc., creates a high potentially risk about poor nutrition and hunger. This case has caused scientists to make researches about new food sources and alternative nutrients. Numerous processes and materials such as algae, edible insects, microbial proteins, microbial oils, in vitro meat, non-dairy and vegan milk and cheese, bio-fermentation technology have been proposed as alternatives by scientists. Besides being healthy of these foods, characteristics such as price, taste, shelf life will be decisive for their acceptance thereof by consumers. However, cultural, religious and social factors may be limiting on the alternative foods. Despite all, future generations will probably eat very different foods for nutrition that we consume today. In this study, it is aimed to give information about possible future alternative food sources and technologies, mainly on protein sources.
Epidemiologia e aspectos imunopatológicos do vírus da imunodeficiência humana (HIV): revisão de literatura
Authors: Melo Bruna De Oliveira de , Rodrigues Lilya Xelle De Brito , Monteiro Joveliane De Melo , Arruda Mariana Oliveira , Bomfim Maria Rosa Quaresma
Published: July 2018

O vírus da imunodeficiência humana (HIV) infecta as células do sistema imunológico do indivíduo provocando uma queda progressiva nos linfócitos T CD4+, debilitando progressivamente o sistema imune e deixando-o mais vulnerável a diversas infecções por patógenos oportunistas e ao surgimento de cânceres de etiologia rara. Este estudo de revisão tem como objetivos explorar os dados epidemiológicos e os aspectos imunopatológicos das infecções pelo HIV-1. As buscas de artigos relacionados ao tema foram feitas nos bancos de dados PubMed; Latin American & Caribbean Health Sciences Literature (LILACS); Scientific Electronic Library Online (SciELO); Science Direct; CAPES (Journal Portal databases) e BIREME (Biblioteca Virtual em Saúde). Os resultados demonstraram que as infecções pelo HIV-1 continuam sendo um grave problema de saúde pública mundial, com as maiores taxas de infecção em países do continente africano e outros países com condições socioeconômicas semelhantes. No Brasil, está ocorrendo um aumento no número de infectados na faixa etária de 50 anos ou mais, com um leve declínio na taxa de infectados nas demais faixas etárias. As principais formas de transmissão do HIV são por relação sexual desprotegida, transfusão de sangue e hemoderivados, compartilhamento de agulhas entre usuários de drogas injetáveis, de mãe para filho durante a gestação, parto e aleitamento materno e, acidentalmente, no ambiente de trabalho, entre profissionais da saúde. A síndrome da imunodeficiência adquirida – AIDS é considerada a última fase da infecção pelo HIV. Entretanto, nos últimos anos, tem sido observado um leve declínio nas taxas de infecção pelo HIV-1, que provavelmente está associada ao sucesso obtido pela terapia com antirretrovirais – drogas que controlam as taxas de replicação do vírus. Contudo, tem sido registrada a ocorrência de resistência clínica aos fármacos que compõem o coquetel de tratamento. Neste sentido, mais estudos são necessários para se ampliar o conhecimento sobre a dinâmica do vírus durante a infecção e interação com as células de defesa humana, a fim de minimizar os efeitos imunopatológicos, bem como para se descobrir potenciais alvos para o desenvolvimento de uma vacina segura e eficaz.

Published: July 2018

Las inmunodeficiencias primarias (IDP) son patologías que tradicionalmente se consideran de la niñez sin embargo los adultos representan el 35% del total de pacientes con IDP. Las deficiencias de anticuerpos, en especial la Inmunodeficiencia Común Variable (IDCV) tienen su pico de incidencia en la edad adulta, requiere un alto índice de sospecha y si bien su frecuencia estimada no es alta (1:25,000), es muy posible que el subregistro y subdiagnóstico si lo sean. El retraso en el diagnóstico aumenta la morbi-mortalidad razón por la cual los médicos de adultos deben estar en capacidad de sospechar, identificar e iniciar el manejo de las personas con IPD. Presentamos el caso de un hombre de 37 años de edad atendido en la sala de urgencias con disnea, fiebre y tos, desarrolla falla respiratoria requiriendo ventilación mecánica. Refería neumonías a repetición desde los 18 años de edad asociadas con bronquiectasias generalizadas. La cuantificación de inmunoglobulinas séricas evidenció hipogammaglobulinemia severa (IgG total <140 mg/dL, IgA total 2.9 mg/dL, IgM total <5 mg/dL), se inició inmunoglobulina humana endovenosa (IGIV) al 10%, y recibió tratamiento antibiótico por 14 días para neumonía severa, su evolución clínica ha sido favorable hasta ahora (un año de seguimiento), se estableció el diagnostico de Inmunodeficiencia Común Variable (IDCV).
Identification of coronary heart disease in asymptomatic individuals with diabetes mellitus: to screen or not to screen
Authors: Bravo Paco Eduardo , Psaty Bruce Mark , Di Carli Marcelo Fernando , Branch Kelley Robert
Published: July 2018

Coronary heart disease (CHD) is highly prevalent in patients with diabetes mellitus (DM), and remains the single most common cause of death among this population. Regrettably, a significant percentage of diabetics fail to perceive the classic symptoms associated with myocardial ischemia. Among asymptomatic diabetics, the prevalence of abnormal cardiac testing appears to be high, raging between 10% and 62%, and mortality is significantly higher in those with abnormal scans. Hence, the potential use of screening for CHD detection among asymptomatic DM individuals is appealing and has been recommended in certain circumstances. However, it was not until recently, that this question was addressed in clinical trials. Two studies randomized a total of 2,023 asymptomatic diabetics to screening or not using cardiac imaging with a mean follow up of 4.4 ± 1.4 years. In combination, both trials showed lower than expected annual event rates, and failed to reduce major cardiovascular events in the screened group compared to the standard of care alone. The results of these trials do not currently support the use of screening tools for CHD detection in asymptomatic DM individuals. However, these studies have important limitations, and potential explanations for their negative results that are discussed in this manuscript.

Mores exists in the community, it happens repeatedly, snd it is supposed to be so. Adat that can lead to sanctions called customary law. Customary law occurs because of social contracts, binding on existing parties within the scope of mores. It treaties made to the public applicable as laws of law and protected by the state, the treaty made must be kept in the covenant of Islam as a debt. Misbehavior is the king's official statement of the recognition of the territorial autonomy of the kingdom that governed himself. Kebangaran Mergo Sekampung Udik is an autonomous region of the Banten government under the sultanate of Maulana Hasanudin. Maulana Hasanudin reigned over Pugung's unity in Lampung, after subduing Pugung's Keratuan through Marriage. In the indigenous communities of Lampung Mergo Sekampung Udik recognize custom Akken Waghei, customs that allow the adoption of family and carried out by adopting an Islamic pledge. Ankken waghei for local people is a solution to maintain good relationships, eradicate family problems, resolve disputes peacefully. Akken waghei can be done with any party, even between tribes.

Published: July 2018

Nanocomposites based on poly(ethylene terephthalate-ethylene dilinoleate) (PET-DLA) copolymers of different hard to soft segment ratios (40:60 and 60:40) and three different carbon nanofillers of different aspect ratios (dimensions), as 0D carbon black, 1D multiwalled carbon nanotubes, and 2D graphene, have been prepared in situ during two-stage polymerization. Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopy were used to characterize the chemical structures of the obtained nanocomposites. Scanning electron microscopy (SEM) indicated very good dispersions of all carbon nanofillers in both polymer matrices. Differential scanning calorimetry (DSC) results revealed that the addition of nano-sized fillers eliminated cold crystallization of materials containing 40% hard segments in polymer matrix. We found that the high aspect ratio, 1D nano-filler (multiwalled carbon nanotubes) strongly nucleated crystallization of materials containing 60% of hard segments. This nanofiller also yielded the greatest improvement in the Young’s modulus as assessed by tensile tests, both at 24 oC and 37 oC. We did not observe reduced bacterial adhesion to nanocomposites, likely due to increased roughness. Importantly, in vitro cytocompatibility tests with L929 murine fibroblasts demonstrated cell viability and growth on all materials except those containing carbon nanotubes. Finally, both high aspect ratio nanofillers markedly improved the barrier properties of obtained nanocomposites. New materials were successfully used for manufacturing of prototype of heart assist device, with pneumatic membrane made of graphene nanocomposite.

Mediante la generación electroquímica de yodo se evalúa la acumulación de Cd(II) por células de tomate de árbol (Solanum Betaceum) a través de la detección de péptidos ricos en cisteína, compuestos sintetizados por la planta cuando está contaminada con metales. La curva de calibración obtenida indica un intervalo lineal de 0 a 250 µmol L-1, con un límite de detección de 4,82 µmol L-1 (3,3 s/m). La concentración de péptidos en las suspensiones celulares incrementa conforme aumenta la concentración de CdSO4 y el tiempo de exposición. Los resultados indican que las células de tomate de árbol acumulan cadmio. Durante 5 días de exposición a 100 µmol L-1 CdSO4 las células en suspensión aún no sufren la apoptosis. El método propuesto muestra características útiles para su implementación en el monitoreo de contaminación por metales pesados en plantas en crecimiento.

Fitria, S.PdPendidikan Olahraga, Universitas Negeri SurabayaPfitria43@gmail.com AbstrakTujuan penelitian ini adalah untuk meningkatkan performa atlet anggar dengan metode latihan imagery dan self-talk. Tujuh siswa yang terpilih sesuai kriteria akan dilakukan pretest untuk menentukan pembagian kelompok imagery, self-talk atau kontrol. Pada penelitian ini akan digunakan dua instrument test, yaitu grid concentration exercise test untuk mengukur tingkat konsentrasi dan kuhadja skill fencing test untuk mengukur ketepatan tusukan. Akan diberikan latihan selama 4 minggu untuk masing-masing kelompok dan 2 kali perlakuan dalam satu minggu. Hasil uji paired sample t-test menunjukkan metode latihan imagery menunjukkan pengaruh yang signifikan pada variabel ketepatan tusukan, kelompok self-talk menunjukkan pengaruh yang signifikan pada variabel konsentrasi dan ketepatan tusukan. Dari data yang diperoleh dapat disimpulkan bahwa kedua kelompok eksperimen ini memiliki peningkatan guna meningkatkan konsentrasi dan ketepatan tusukan, walaupun dengan jumlah rerata yang tidak sama, hal ini bisa disebabkan karena keterbatasan waktu yang ada dan minimnya pertemuan treatmen per mingu yang diberikan.Kata Kunci : ketepatan tusukan, konsentrasi, latihan self-talk, imagery

Published: July 2018

We have introduced the notion of $\alpha$-prime and weakly $\alpha$-prime submodules as a generalization of prime submodules. Some basic properties of $\alpha$-prime and weakly $\alpha$-prime submodules are the extension of prime submodules. Finally, after introducing the notion of $\alpha$-prime submodules, we also define and study the concept of $\alpha$-prime ideals in a ring.

In this paper, we introduce the concept of slightly compressible-injective modules, following this, a right R-module N is called an M-slightly compressible-injective module, if every R-homomorphism from a non-zero M-slightly compressible submodule of M to N can be extended to M. We give some characterizations and properties of slightly compressible-injective modules.

Published: July 2018

In this article we consider the numerical approximation of lower bounds of Structured Singular Values, SSV. The SSV is a wellknown mathematical quantity which is widely used to analyse and syntesize the robust stability and instability analysis of linear feedback systems in control theory. It links a bridge between numerical linear algebra and system theory. The computation of lower bounds of SSV by means of ordinary diï¬€erential equations based technique is presented. The obtained numerical results for the lower bounds of SSV are compared with the well-known MATLAB function mussv available in MATLAB control toolbox.

Published: July 2018

Вагітність і пологи є значним фізичним навантаженням на організм кожної жінки. Виношування плода та пологова діяльність вимагають від вагітної посиленого функціонування всіх органів і систем організму. Мета дослідження – теоретично обґрунтувати особливості проведення фізичної реабілітації вагітних жінок у передпологовому періоді. Представлений у статті матеріал свідчить, що рухова активність під час вагітності сприяє нормалізації психологічного стану жінок у процесі вагітності, формуванню родової домінанти, перешкоджає розвитку стресу та сприяє збереженню й зміцненню здоров’я матері та потомства, а тим самим – і здоров’ю сім’ї. Також фізичні вправи дають змогу ефективно підготуватися до пологів і сприяти швидкому протіканню пологового та післяпологового періоду. У них виникають позитивні емоції, покращується настрій, створюється впевненість у сприятливому перебігу вагітності, повноцінному розвитку плода, подоланні труднощів із його виношуванням і під час пологів та народження нормальної здорової дитини. Вагітні, які займалися фізичними вправами за запропонованою програмою, відзначили тонізуючий, оздоровчий і загальнозміцнювальний ефект занять.
