Abstract. Rubber seed Hevea brasiliensis contains relatively high oil and potentially used in a diet as sources of fatty acid and energy as well. A study, therefore, was conducted in the aim of evaluating the use of rubber seed oil as a substitution of soybean oil in the diet for increasing growth performance of common carp. The treatments were the substitution of rubber seed oil to soybean oil at a respectived level of 0, 25, 50, 75 and 100%, each treatment had three replications. Test diet contained Cr2O3 as digestibility indicator. After acclimatization, common carp fingerling of 3.55 ± 0.00 g in average weight was randomly stocked in 15 aquaria of 69x29x35 cm3 in dimension size containing 50 L water at 15 fingerlings per aquarium and fed iso-protein and iso-energy test diet at satiation for 40 days of the experimental period. Feces in each tank were collected at day 3 for 15 days. Parameters tested were digestibilities of total and fat, diet consumption, growth, protein/fat retention, and survival. The results showed that the more increase rate of substitution of rubber seed oil in the diet, the more significantly declining diet digestibility and growth performance of common carp (P0.05). It is concluded that the substitution of rubber seed oil to soybean oil as much as 25% in diet resulted in the highest diet digestibility and growth performance of common carp.Keywords: Common carp, Digestibility, Rubber Seed Oil, Soybean Oil, Growth Performance Abstrak. Biji karet Hevea brasiliensi mengandung lemak relatif tinggi dan berpotensi digunakan dalam pakan ikan sebagai sumber asam lemak dan energi. Oleh karena itu, suatu penelitian telah dilakukan dengan tujuan untuk mengevaluasi penggunaan minyak biji karet dalam pakan sebagai substitusi minyak kedelai untuk peningkatan kinerja pertumbuhan ikan mas Cyprinus carpio. Perlakuannya adalah substitusi minyak biji karet terhadap minyak kedelai pada tingkat 0, 25, 50, 75, dan 100%, masing- masing perlakuan mempunyai tiga ulangan. Pakan uji mengandung Cr2O3 sebagai indikator kecernaan. Setelah diadaptasikan, ikan mas dengan bobot rata-rata 3,55 ± 0,00 g ditebar ke dalam 15 akuarium ukuran 69x29x35 cm3 berisi 50 L air dengan padat tebar 15 ekor/ akuarium dan diberi iso protein dan iso enerji pakan uji secara sekenyangnya selama 40 masa percobaan. Uji kecernaan dilakukan selama 15 hari dan uji pertumbuhan selama 40 hari. Parameter uji yang digunakan adalah kecernaan total dan lemak, konsumsi pakan, pertumbuhan, retensi protein/lemak dan sintasan. Hasil penelitian menunjukkan bahwa semakin meningkat substitusi minyak biji karet, secara nyata semakin menurun kecernaan pakan dan kinerja pertumbuhan ikan mas (P0,05). Oleh karena itu substitusi minyak biji karet terhadap minyak kedelai sampai dengan 25% menghasilkan kecernaan pakan dan kinerja pertumbuhan ikan mas terbaik.Kata Kunci: Ikan mas, Kecernaan, Minyak biji karet, Minyak kedelai, Pertumbuhan

BACKGROUND The ileum is the most vulnerable part of the small intestine that plays an important role as the motor of multisystem organ failure. Villous damage is demonstrated after ligation of supply artery in mice; however, there is no study on the ileum after distant ischemic organs. Thus, this study was aimed to find out ileal villous changes following reperfusion injury, the protective effects of ischemic hypothermia and ischemic preconditioning.METHODS An experimental study conducted enrolled 21 subjects of Oryctolagus cuniculus. Ischemia is induced by ligation of the femoral artery for 4 hours. Eight hours after ligation was released, ileum and duodenal specimens were taken through laparotomy. H&E stained specimens were examined for histomorphological changes. Villi change scores, tissue level of hypoxia-inducible factor-1α (HIF-1α), malondialdehyde (MDA), and occludin were statistically analyzed in four treatment groups, namely ischemia, ischemic hypothermia, ischemic preconditioning, and control.RESULTS Intestinal villi changes were found following ischemic-induced arterial ligation. Ileal villi changes showed differences with the duodenum and controls as indicated by the villi damage scores, increased tissue HIF-1α and MDA, and decreased occludin levels. Ileal villi changes in the ischemic and ischemic hypothermia groups showed significant changes with controls; whereas the ischemic preconditioning group showed no significant differences.CONCLUSIONS Ischemia at a distance leads to both histomorphological and biochemical damage of the ileal villi and disrupts the integrity of the intestinal mucosal barrier. In addition, the study showed a protective effect of ischemic preconditioning.

BACKGROUND Women in menopause experience dramatic alterations in gonadal hormone concentrations, including diminished estradiol levels. It has been hypothesized that these hormonal changes may be responsible for the occurrences of menopausal symptoms, such as hot flushes, sleep disruption, night sweats, and irritability, as well as mild cognitive impairment (MCI) in postmenopausal women. Therefore, this study was aimed to determine if there is any association between hormonal changes and menopausal symptoms, including MCI in postmenopausal women.METHODS A total of 245 postmenopausal women were recruited for this cross-sectional study and classified into 2 groups; MCI and non-MCI groups. Diagnosis of MCI was made using the modified Petersen criteria. Variables such as subjects’ age, duration of menopause, menopausal symptoms, anthropometric status, hormone levels, and cognitive status were assessed and statistically analyzed.RESULTS Of the 245 subjects enrolled in this study, 53.9% had MCI. Multivariate analysis found that sleep disruption and estradiol levels were independent risk factors of MCI in postmenopausal women. No significant correlation was found between menopausal symptoms and estradiol concentration.CONCLUSIONS Low estradiol levels were associated with higher risks of experiencing menopausal symptoms and MCI. Sleep disruption and estradiol levels were the most influential factors in the development of MCI in postmenopausal women.

BACKGROUND The incidence of multiple pregnancies in industrialized countries due to the use of assisted reproductive techniques has increased over the past two decades. Multiple births are more dangerous than single pregnancies for mother and baby. This study evaluated the frequency of multiple pregnancies and its neonatal complications.METHODS In this cross-sectional study, we assessed all multiple neonates hospitalized in Fatemieh Hospital of Hamadan, Iran from September 2016 to September 2017 in terms of gender, gestational age, birth weight, the use of assisted reproductive techniques, delivery method, cause of hospitalization, therapeutic intervention, and hospitalization outcome.RESULTS Of 10,581 deliveries during the study period, 351 (3.3%) was multiple pregnancies and 232 neonates hospitalized. The incidence of twin, triplet, and quadruplet birth were 1.7%, 0.39%, and 0.11% respectively. In this study, 178 twin and 54 triplet and quadruplet birth were compared. The mean gestational age and mean birth weight of triplet and quadruplet were lower than that of twin births (p<0.001). A significant difference was found on the frequency of assisted reproductive techniques (p<0.001). Female sex (p=0.007), lower mean gestational age (p=0.009), lower mean birth weight (p=0.017) and need to mechanical ventilation (p<0.001) were significantly associated with early neonatal death in multiple pregnancies.CONCLUSIONS The incidence of multiple births was high in the Hamadan province, which was often followed by infertility treatment. Moreover, multiple births cause prematurity, low birth weight, respiratory distress syndrome, and increased neonatal mortality rate.
O fruto que restitui o fio do tempo e da identidade. Reelaboração do trauma da tortura em mulheres em Que bom te ver viva
Authors: Monay Ana Carolina 
Published: May 2019

O período da história do Brasil compreendido entre 1964 e a segunda metade da década de 1980 foi marcado por uma ditadura implementada pelas Forças Armadas mediante um golpe de Estado. Para combater um imaginário "inimigo internoâ€, foi montada no coração do Estado uma robusta engenharia repressiva. Peça-chave ou motor, a instituição da tortura possibilitava o giro dessa engrenagem. Para além da captura de informações, a tortura objetivava expor o sujeito torturado a uma situação-limite capaz de provocar cesuras traumáticas nas possibilidades de articulação da identidade. Em 1989, contexto de redemocratização do Estado, Lúcia Murat, que fora organizada na resistência Ã Ditadura, lança seu primeiro filme de longa-metragem. Em Que bom te ver viva (1989) é tecida uma denúncia pública da violência da tortura em mulheres, tratando da origem do trauma e da vivência com/apesar dele. Desse modo, o presente trabalho analisa o argumento de Que bom te ver viva (1989), observando que se no evento gerador da cesura - a tortura - o controle do uso da especificidade da mulher, exprimido em uma forma de dupla punição às mulheres por transgredirem duas ordens - a do Regime Militar e do Regime patriarcal -, se encontrava nas mãos dos algozes, as possibilidades de restituição da fratura do fio identitário se deram, justamente, através da retomada deste controle, que se traduziu em uma forma específica de resistência feminina: a maternidade.
O Regimento Inquisitorial de 1774: modernização e dirigismo cultural nos tribunais de fé no reformismo pombalino
Authors: Rocha Igor Tadeu Camilo 
Published: May 2019

O objetivo deste artigo é analisar o Regimento da Inquisição de Portugal de 1774 e sua articulação com um dirigismo cultural marcante no reformismo pombalino a partir da segunda metade do século XVIII. Tratam-se de políticas tocantes às instituições públicas, sociais, culturais e religiosas de Portugal e colônias, que partiam de uma premissa de que o atraso atribuído a Portugal em relação às nações do norte da Europa seria superado com reformas feitas verticalmente. Para tanto, seria necessária a permanência de instituições como os órgãos de censura e a Inquisição, desde que reformadas e modernizadas, readequadas a "iluminar" as mentalidades, guiando-as rumo Ã uma razão iluminista delimitada pelo ideário cristão católico. O Regimento da Inquisição de 1774 ao mesmo tempo em que modernizava as formas de punir com a supressão da tortura, das penas públicas como os autos de fé e publicação de listas de penitenciados, terminou com o segredo processual e ainda modificou categorias penais, como, por exemplo, retirando "possessão demoníaca" como evidência válida para delitos como os de feitiçaria. Ele se norteava por um ideal de pureza de fé, de um lado, e secularizador, de outro, contrário tanto à irreligião quanto às formas consideradas supersticiosas e fanáticas de religião. Será discutida a ambiguidade de um regimento inquisitorial que dialogou com os diversos debates iluministas a respeito da aplicação e tipificação de delitos e penas, a despeito do fato de a crítica Ã repressão das diferenças de religião ser uma tópica fundamental das Luzes.

O presente artigo parte da premissa de que cabe à escola promover, por meio da educação científica, condições para o exercício da cidadania crítica e ativa. Resulta de uma investigação realizada com a finalidade de avaliar a importância da discussão de dilemas éticos para uma compreensão adequada da ciência e para a promoção da vivência cidadã. A motivação pela temática ocorreu a partir da leitura do livro "A vida Imortal de Henrietta Lacksâ€. As atividades investigativas foram desenvolvidas por meio da metodologia IBSE-7E's, integrando no currículo as ferramentas da Web 2.0. Os resultados indicaram que o exercício da cidadania de forma crítica e ativa está relacionado com a capacidade dos cidadãos avaliarem criticamente os efeitos da ciência e da tecnologia na sociedade. Depreende-se disso, de que a discussão de temas controversos dessa natureza precisam ser considerados na educação científica escolar para que a mesma atinja as suas finalidades.

Non-local Degenerate Diffusion Coefficients Break Down the Components of Positive Solutions
Authors: Delgado M. , Morales-Rodrigo C. , Santos Júnior J. R. , Suárez A. 
Published: May 2019

Abstract
This paper deals with nonlinear elliptic problems where the diffusion coefficient is a degenerate non-local term. We show that this degeneration implies the growth of the complexity of the structure of the set of positive solutions of the equation. Specifically, when the reaction term is of logistic type, the continuum of positive solutions breaks into two disjoint pieces. Our approach uses mainly fixed point arguments.

Zusammenfassung
Nach dem Zweiten Weltkrieg waren die Bemühungen um den Auf- und Ausbau des deutschen Bibliothekswesens vornehmlich auf die Universitätsbibliotheken gerichtet, während die Landesbibliotheken als Stätten des historischen Erbes ihrer jeweiligen Regionen an den Rand gedrängt zu werden drohten. Ihr maßgeblich von Dr. Hermann Sauter (Landesbibliothek Speyer) initiierter Zusammenschluss zur Arbeitsgemeinschaft der Landesbibliotheken im Jahre 1958 verschaffte ihnen bibliothekspolitisches Gewicht: 1964 fanden sie Einlass in die „Empfehlungen des Wissenschaftsrates zum Ausbau der wissenschaftlichen Einrichtungen“. Durch die Vereinigung mit der Arbeitsgemeinschaft der kommunalen wissenschaftlichen Bibliotheken im Jahre 1971 entstand die Arbeitsgemeinschaft der Regionalbibliotheken. Der vorliegende Beitrag blickt zurück insbesondere auf die Anfänge dieser sechzigjährigen Geschichte, skizziert aber auch in groben Zügen deren weiteren Verlauf. Er wurde in verkürzter Form auf der Herbsttagung der Arbeitsgemeinschaft der Regionalbibliotheken als Festvortrag präsentiert.
Sovereign default and the structure of private external debt
Authors: Siwińska-Gorzelak Joanna , Brzozowski Michał 
Published: May 2019

AbstractWhile the literature on determinants of sovereign default is voluminous, the links between private indebtedness and the probability of public bankruptcy have not been studied extensively. In this paper we aim to fill this gap and to shed more light on the influence of the size and structure of private debt on sovereign default probability. We focus on developing and emerging market economies over the years 1970–2012. The main conclusions are that both the size and the structure of private borrowings affect the probability of a sovereign default.
Regional dimension of firm level productivity determinants: the case of manufacturing and service firms in Ukraine
Authors: Cieślik Andrzej , Michałek Jan Jakub , Gauger Iryna 
Published: May 2019

AbstractThe main goal of this paper is to empirically investigate the regional dimension of productivity determinants for 24 regions of Ukraine using micro-level dataset for individual firms in 2013. The novelty of our analysis is the comparison of the determinants of productivity in the manufacturing and service sectors. We estimate both pooled regressions for all regions and separate regressions for particular regions. The estimation results obtained for the entire country demonstrate that the majority of our explanatory variables are statistically significant for the manufacturing sector and all are statistically significant for the service sector although at different levels of significance. At the same time, the estimation results obtained separately for each region show a large degree of heterogeneity across the regions and sectors and the lack of scale economies at the firm-level.
