Obtenção de sistemas macroemulsionados a partir de óleos vegetais, para incorporar extrato seco de punica granatum

As emulsoes sao formulacoes empregadas em diferentes segmentos da industria, principalmente na area alimenticia, terapeuticas, cosmeticas. Os oleos de Linum usitatissimum e Sesamun indicum apresentam propriedades anti-inflamatorias, em razao da presenca de acidos graxos essenciais, podendo ter aplicacao na preparacao de medicamentos pelo potencial farmacologico. O objetivo desse trabalho foi usar as propriedades farmacologicas do Punica granatum, como ativo, em sistema emulsionado, para aplicacao fitoterapica. As emulsoes foram obtidas a partir de diagrama ternario utilizando a agua destilada como fase aquosa e a lecitina de Glycine max como tensoativo. Na preparacao dos dois diagramas, na fase oleosa, utilizou-se os oleos de Linum usitatissimum e Sesamun indicum. Nos diagramas obtidos, na regiao de emulsao do tipo O/A, foram escolhidos seis sistemas (tres em cada diagrama) por apresentar maior estabilidade. Os conservantes adicionados aos sistemas foram metilparabeno (Nipargin) e propilparabeno (Nipazol) e o estabilizador de emulsoes, hidrocoloide Xanthan Gum (goma xantana). Da casca do vegetal Punica granatum foi obtido extrato aquoso, e em seguida liofilizado. Foram definidos tres percentuais (0,3%, 0,5% e 1,0%) de extrato liofilizado em cada sistema. Essas formulacoes foram caracterizadas atraves das tecnicas de medida pH, viscosidade, condutividade, estabilidade acelerada e estabilidade termica. Antes de adicionar o bioativo foi empregada a espectrofotometria no Ultravioleta para quantificar o bioativo presente no po da casca da roma. A formulacoes com a adicao do extrato tiveram seus valores de pH diminuidos e viscosidade aumentada quanto maior foi o percentual do extrato no meio. Isso se deve por que o extrato apresenta fenois de carater acido e a quantidade maior de extrato no meio precisa de mais moleculas para hidratar esse extrato, tornando o meio com menos agua livre.
A Critical Fast Ion Beta in the Madison Symmetric Torus Reversed Field Pinch

The first fast-ion profile measurements have been made in a reversed-field pinch (RFP) plasma. A large population of fast-ions are deposited in the core of the Madison Symmetric Torus (MST) through use of a 1 MW neutral beam injector (NBI) giving rise to a variety of beam-driven instabilities. One such mode, the energetic-particle mode (EPM) has been shown to reduce fast-ion content in MST, evident through drops in signal levels of the advanced neutral particle analyzer (ANPA). EPMs in MST appear as bursts of magnetic fluctuations at a lab frequency of ∼100 kHz reaching peak amplitude and decaying away within 100μs. A burst ensemble of the neutron data does not reveal a drop in neutron emission across a burst, implying the population of fast-ions transported by a burst constitute a small fraction of the total. The burst may also pitch-angle scatter out of the ANPA phase space or be transported to mid-radius where charge-exchange with the background neutrals or fast-ion orbit stochasticity may reduce fast-ion confinement. Data gathered from the expanded neutron diagnostic suite including a new collimated neutron detector (CiNDe) was used to reconstruct the fast-ion profile in MST and measure critical βf quantities. Measurements were made in plasma conditions with varying magnetic field strength in order to investigate the interplay between the energetic particle (EP) drive and Alfvén continuum damping. The measured values of βf (0) (7.5% (1.2%) in 300 (500) kA plasmas) are reduced from classical predictions (TRANSP predicts up to 10% core value) due to EPM activity. The frequency, magnitude, and rate of occurrence of the bursts depends on the tearing mode amplitude, Alfvén continuum damping rate, fast-ion profile shape, and resonant orbit dynamics. Marginal stability was reached in both moderate(300 kA) and high(500 kA) current discharges, marked by sustained EPM activity and a saturated global neutron signal during NBI. The difference in profile shape is interpreted to be related to the core-most resonant tearing mode amplitude, as a larger core magnetic island moves the location of steepest
Systematic density functional theory study of the structural and electronic properties of constrained and fully relaxed (0 0 1) surfaces of alumina and hematite

Abstract Owing to their widespread use in a variety of technological applications, as well as their prevalence as naturally occurring phases in the environment, there is a prolific amount of computational research devoted to the surfaces of metal oxides. However, there is no standard approach for how to best represent the surface structurally in quantum mechanical modeling, specifically in the standard supercell slab geometry that is amenable to density functional theory calculations that employ periodic boundary conditions. There is a choice in both slab thickness and in how the atomic positions are treated during geometry optimisations; the atomic coordinates can either be fully relaxed or partially fixed. Constraining the atomic positions of select layers of the slab can decrease overall computational cost and is often reported to have a minimal effect on the details of the optimised geometries. In this study, we compare fully relaxed structures of alumina () and hematite () (0 0 1) surfaces to two slab models in which either one or two stoichiometric layers, denoted as trilayers, are constrained to bulk positions. We go on to study the electronic structure of the slab models, and we also assess how modeled reactivity is affected through studies of atomic chemisorption on the slab models. Our results suggest that while structural differences between partially constrained or fully relaxed slab models may be subtle, both the electronic structure and modeled reactivity can vary significantly in quantitative and qualitative ways.
Search for second order response of nuclei to isospin probes and their connection to double beta decay

In order to get quantitative information on neutrino absolute mass scale from the possible measurement of the 0νββ decay half-lives, the knowledge of the Nuclear Matrix Elements (NME) involved in such transitions is mandatory. NMEs are not observables and can only be accessed by theory. However, the many-body nature of the nuclear state involved in the decay, makes this task possible only at approximate level. In this perspective, several experimental approaches have been proposed in the years in order to provide useful information to better constrain the theory. Here a short overview of the role of charge exchange reactions in this scenario is given, with particular emphasis on second order processes, known as Double Charge Exchange (DCE) reactions.
An Experiential Learning-Based Integrated Policy Advocacy Education Model in Hong Kong: What Works in a Non-Western and Partial Democratic Context?

ABSTRACT This study examined the effectiveness of an experiential learning-based integrated policy advocacy education model in Hong Kong, a partially democratic and non-Western society. The model incorporated guest lectures, a mock hearing, a site visit, and an advocacy project. A mixed methods evaluation involving 144 students in quantitative surveys and 9 students in focus groups demonstrated that this model increased students’ levels of political activity, political efficacy, competence in advocacy, and their intention to take future advocacy action despite what some have perceived to be a pessimistic and ambivalent environment for advocacy in Hong Kong. Interviews with six advocates also suggest that an ideal advocacy education model should incorporate theoretical teaching, social justice values, sharing experiences of field experts, practice, and action.
The effect of Confucian culture on corporate tax avoidance: evidence from China

Abstract This study investigates whether Confucian culture can influence corporate tax avoidance. We measure Confucianism using geographical-proximity based method and opt ordinary least square regression considering a sample of Chinese firms during 2004–2016. We find strong evidence that Confucian culture and tax avoidance are negatively associated and this association is less prominent for state-owned firms. Additional analysis shows that tax enforcement efforts mitigate the effect of Confucianism on tax avoidance. The results are consistent and robust to alternative measures of tax avoidance and Confucianism. Overall, the findings enrich our understanding that Confucian culture reduces tax avoidance by promoting corporate ethical behavior.
Pursuing Quality Education in Karamoja. An Analysis of the Caregivers’ Quality Indicators from a Community Perspective for Sustainable Early Childhood Education Programmes

Purpose of the study: The purpose of the study was to analyze the caregivers’ quality indicators from a community perspective for sustainable ECE programmes.Methodology: The study employed a qualitative approach that used phenomenology research design. Twenty-five interviews and ten focus group discussions were used on the respondents for collecting data. The data collected from the caregivers/teachers, elders, parents and Early Childhood Education focal point officers revealed that the Ministry of Education and Sports caregiver quality indicators are not much emphasised in Karamoja. Findings: While the ECE learning framework wants caregivers to promote holistic development of children, the karimojong community wants caregivers to focus more on their culture. A good ECE caregiver for Karamoja should be able to honour the histories, culture, language, traditions, child rearing practices and lifestyle choices of the communities.Unique contribution to theory practice and policy: The findings indicate that there is need for stakeholders to work together to identify the caregivers ECE quality indicators then support in the designing, implementation and supervision of the ECE programmes for sustainability. If researchers use the strengths of communities, enshrined in their funds of knowledge, we are more likely to tap into their reserve support for ECE interventions. The social capital theory therefore when correctly implemented helps the caregivers and the education sector in working collaboratively with the parents in the setting up systems that aim at sustainable ECE programmes in the communities.
Komposisi Kimia Baby Fish Nila Larasati (Oreochromis niloticus) Pada Berbagai Umur Panen dalam Sistem Akuaponik

Baby fish tilapia is mostly consumed by society in fried the fish and crispy forms, but the information on the nutritional composition of the fish is limited. The objective of the present study was to evaluate the chemical composition and fatty acids of baby fish tilapia harvested in different periods reared under aquaponic system. The research was conducted in factorial design with single factor namely different harvesting periods (14 days, 21 days, 28 days, and 35 days). The parameters measured were morphometric (body weight, total length and body length), chemical composition, and fatty acids. The results showed that the body weight affected the chemical composition. Statistical analysis showed that the proximate analysis was significantly different among the treatments (p<0.05). The highest saturated fatty acid (SAFA) and polyunsaturated fatty acid (PUFA) was palmitate (C6:0) dan linoleat (C18:2n6) respectively obtained at fish harvested in 14 days.
Formulações analíticas e numéricas para caracterização do fenômeno oscilação de potência em linhas de transmissão

Este artigo apresenta formulacoes analiticas e numericas para caraterizacao do fenomeno oscilacao de potencia em linhas de transmissao. As perturbacoes sistemicas que afetam o balanco carga-geracao podem ocasionar a aceleracao ou o atraso do ângulo do rotor dos geradores sincronos em relacao a frequencia sincrona, dando origem as oscilacoes de potencia. O impacto deste fenomeno nos terminais das linhas consiste essencialmente em flutuacoes dos valores de tensao e corrente, podendo ocasionar atuacao indevida da funcao de distância (ANSI 21) em reles de protecao. Neste trabalho e utilizado o modelo classico de duas maquinas para obtencao das grandezas corrente, tensao, potencia ativa, potencia reativa, impedância e velocidade da impedância, durante oscilacoes. Para isso, foram implementados no MATLAB® metodos analiticos e numericos para a determinacao de grandezas instantâneas e fasoriais. O comportamento dos sinais obtidos e o efeito da oscilacao de potencia na trajetoria da impedância no plano RX dos reles de distancia sao analisados. Para validacao das solucoes empregadas e utilizado o Alternative Transients Program (ATP). Por meio dos resultados constatou-se que a velocidade da impedância e a potencia ativa sao as principais grandezas que caracterizam o fenomeno, visto que durante uma oscilacao de potencia a velocidade da impedância e substancialmente inferior a de curtos-circuitos, e o fluxo de potencia ativa varia ciclicamente em modulo e direcao.
Rumor spreading model considering the influence of public opinion environment

Rumor spreading has a profound influence on daily lives. There are several factors influencing rumor spreading. In this paper, we assume that there are two kinds of individuals in the crowd: those who do not know the rumors and those who learn about the rumors. And in the latter category, there are two attitudes toward rumors: those who are convinced of rumors and those who hold an objective attitude. Those convinced and objective individuals form a public opinion environmental factor conducive to the spread of rumors. Based on the public opinion environmental influence whose intensity decays with time, a model with two attitudes toward rumors is established. With numerical simulations, we illustrated the conversion state of three categories because of public opinion environmental factors, analyzing the sensitivity of the model. The results showed that it is beneficial to control the rumor propagation when controlling the influence of those who are convinced of rumors and those who hold an objective attitude rather than constraining one of them individually. And it was commonsensical that increasing the attenuation intensity of the two attitude rumors was also an effective way conducive to the control.
Passagerforsinkelser: Model og casestudie :

Nar passagerer rejser med kollektiv transport, vil langt storstedelen opleve, at en eller flere af deres forbindelser afvigelser fra den publicerede koreplan. Selvom det langtfra er ligetil at afgore hvordan koretojsforsinkelser influerer passagerenes endelige ankomster, er det abenlyst, at der er en sammenhaeng mellem de to. I dette studie skaber vi denne sammenhaeng ved at praesentere en adaptiv rutevalgsmodel, der tillader passagerer at reagere pa forsinkelser og realtidsinformation, saledes at de lobende optimerer deres rutevalg for at ankomme pa den mest hensigtsmaessige made. Flere scenarier for realtidsinformation er testet i et storskala casestudie for Hovedstadsomradet, hvor passagerforsinkelser modelleres for 65 dage, fra hvilke realiserede koretojsforsinkelser for bus og tog er anvendt. Modellen er storskalaanvendelig med beregningstider under realtid. Resultaterne viser som ventet at passagerforsinkelserne har langt storre variation end koretojsforsinkelser, og at passagerforsinkelserne reduceres ved oget realtidsinformation.
FTIR spectroscopic analysis of protein/carrier interactions in novel protein delivery systems

The objective of this work was to investigate the binding of calcitonin to complexation hydrogels composed of poly(methacrylic acid) (PMAA) grafted with polyethylene glycol) (PEG), henceforth designated as P(MAA-g-EG). This was done to investigate the complexation and decomplexation of these hydrogels in buffered solutions, using attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy. P(MAA-g-EG) hydrogel films were prepared by free radical solution polymerization using the spin coating method. The ensuing films were tested directly on Ge crystals. Carbonyl ion peaks were used to identify protein/P(MAA-g-EG) binding due to electrostatic and hydrogen bonding interactions between the complexation hydrogel and the protein. As the pH values increased, the asymmetric and symmetric stretching vibrations appeared in the spectra identifying the C(=O)-O functional group. In addition, the binding of calcium to P(MAR-g-EG) hydrogels was investigated to elucidate the complexation mechanism.
Quantum Descriptors and Corrosion Inhibition Potentials of Amodaquineand Nivaquine

Amodaquine [4-[(7-chloroquinolin-4-yl) amino]-2-(diethylaminomethyl) phenol] and nivaquine (4-N-(7- chloroquinolin-4-yl)-1-N,1-N-diethylpentane-1,4-diamine sulphate) has been studied as potential source of green inhibitor for corrosion of aluminium in 1 M HCl at different concentrations using gravimetric method. To further elucidate the reactivity and efficiency of these anti-malaria drugs as potential corrosion inhibitors, quantum chemical calculations using Density Functional Theory (DFT) method in conjuction with Becke 3 Lee Yar Parr (B3LYP)/6-311++G** level of theory was applied. Kinetics and thermodynamic parameters central to surface adsorption were calculated and discussed. Results revealed that the inhibition efficiency increased as the inhibitor concentration increased but decrease with an increase in temperature with Nivaquine having better inhibition efficiency than Amodaquine. The adsorption of Amodaquine and Nivaquine on the surface of aluminium both followed the Freundlich adsorption isotherm at all concentrations and temperatures. The negative value of ΔGads obtained indicates spontaneous adsorption of the inhibitor on the aluminium surface and a low negativity indicates electrostatic interactions between inhibitor and the charged metal surface.
LA FUERZA MÁXIMA EN PRESS BANCA PLANO NO ESTA INFLUENCIADA POR LA REPETICIÓN MÁXIMA DE EJERCICIOS ACCESORIOS

La realizacion de ejercicios accesorios (EA) en los programas de entrenamiento de fuerza con sobrecargas (EFS) es una practica bastante difundida para obtener mayores beneficios en la fuerza e hipertrofia muscular, sin embargo, no existen estudios que correlacionen la repeticion maxima (RM) de ejercicios accesorios y el press banca (PB). Por ende, el objetivo del presente estudio exploratorio de tipo correlacional y una muestra a conveniencia fue determinar el grado de correlacion entre la repeticion maxima de ejercicios accesorios de miembros superiores y la repeticion maxima en PB en sujetos practicantes de musculacion. Participaron voluntariamente catorce hombres sanos (edad 22,45±2,45 anos, talla 1,69±0,07 m, masa corporal de 66,5±13,11 kg) capacitados en el EFS, el test de RM se realizo en tres dias separados por 48 horas, y, los ejercicios valorados fueron: PB, remo en polea baja (RP), press militar con barra (PM), biceps en polea (BP), triceps en polea (TP), jalon a la cara en polea (JP) y encogimientos con barra (EB). El analisis de los datos se realizo en el paquete estadistico IBM SPSS V.22 con un nivel de confianza del 95% en el cual se aplico la prueba de normalidad (Shapiro-wilk) y el coeficiente correlacional de Pearson teniendo en cuenta para la significancia un p-valor de 0,05. Los resultados de la repeticion maxima en todos los ejercicios manifestaron una distribucion normal (p>0,05), sin embargo, la relacion entre el PB con RP (r = -0,49), PM (r = 0,48), BP (r = 0,07), TP (r = -0,09), JP (r = 0,37) y EB (r = 0,09) no fue significativa (p>0,05). En conclusion, los ejercicios valorados no estan relacionados significativamente con la repeticion maxima en press banca plano en sujetos practicantes de musculacion.
Suboptimal Birthweight and Adult Cardiometabolic Disease: The HPA-Axis Link

Introduction Suboptimal birthweight (<10th percentile, >90th percentile) has a well-established relationship with several adult cardiometabolic risk factors, including obesity, dyslipidaemia and elevated blood pressure (BP) [1]. Over the past three decades, several animal studies have investigated this relationship. Together, these studies have shown that in sub-optimally grown offspring, adaptive changes occur in key organ systems to maximize chances of ex-utero survival [2]. Unfortunately however, these early life adaptations to organ structure and function render suboptimally grown offspring vulnerable to chronic disease later in life [3]. This concept is known as the Developmental Origins of Health and Disease (DoHAD) hypothesis, and provides the broad mechanistic framework underpinning the relationship between adverse early life exposures and chronic disease in adulthood [2]. The hypothalamic pituitary adrenal axis (HPA-A) plays a key role in cardiometabolic homeostasis by regulating tissue exposure to endogenous glucocorticoids [4]. Several animal studies have shown that the axis is highly susceptible to adaptive change in response to adverse early-life exposures [5].
Association between anti-complement factor H antibodies and renal outcome in primary membranous nephropathy.

AIMS The complement factor H (CFH) is a regulator for the alternative complement pathway. The prevalence and roles of anti-CFH antibodies in the clinical outcome of primary membranous nephropathy (MN) patients remain unclear. MATERIALS AND METHODS A total of 106 biopsy-proven kidney disease patients and 18 healthy controls were retrospectively investigated in this study. 36 patients had primary MN and 70 patients were diseased controls (31 minimal change nephrotic syndrome (MCNS), 19 rapidly progressive glomerulonephritis (RPGN), and 20 IgA glomerulonephritis (IgAGN)). Serum anti-CFH antibody titers were measured by enzyme-linked immunosorbent assay. RESULTS 77.8% of MN patients were positive for anti-CFH antibodies. However, only 27.1% of diseased control patients and 5.6% of healthy controls were positive for anti-CFH antibodies. Moreover, median anti-CFH antibody titers were significantly higher in MN patients (4.69 AU/mL) than in diseased control patients (MCNS patients (0 AU/mL, p < 0.01), RPGN patients (0 AU/mL, p < 0.05), IgAGN patients (0 AU/mL, p < 0.01)), and healthy controls (0 AU/mL, p < 0.01). Anti-CFH antibody titer was selected as an independent unfavorable predictor of renal dysfunction by Cox proportional hazards analysis. CONCLUSION These data suggest that anti-CFH antibodies may be involved in the deterioration of renal function in primary MN.
STUDY COMPARATIVE OF ANTENNA FOR MICROWAVE IMAGING APPLICATIONS

AbstractMicrowave can be applied for telecommunicaions, radar and microwave imaging. This wave has been widely used in everyday life, such as in the industrial word in the fields of robotics, microwave vision, imaging burrier objects, vehicular guidance, biomedical imaging, remote sensing, wheater radar, target tracking, and other apllications. Microwave imaging is a technology that uses electromagnetic waves at frequencies from Megahertz to Gigahertz. Utilization of microwave imaging in addition to information technology and telecommunications, this wave application can be used to process an image because of its ability to penetrate dielectric materials. The purpose of writing this article is to determine microwave imaging application, the working principle of antennas used for microwave imaging applications and antenna specifications used for microwave imaging applications. Microwave imaging research has been carried out using several different type of antennas such as vivaldi and monopole antennas. Where the signal tha is transmitted and will be exposed to the object will send a different return signal so that an image of an object will be obtained which will be processed on the computer. The working frequency of the antenna for microwave imaging applications is in a wide frequency range (UWB antenna). The antennas that are applied include the vivaldi antenna which works at a frequency of 1-11 GHz and a monopole antenna that works at a frequency 1,25-2,4 GHz for biomedical imaging applications, while for radar applications in the construction field it can use a frequency of 0,5-40 GHz.
