Objetivo. Identificar o consumo de ferro no período menstrual por mulheres em idade reprodutiva. Métodos. Tratou-se de uma pesquisa de caráter descritivo, do tipo transversal, com coleta de dados primários, realizada com 76 estudantes do curso de bacharelado em Nutrição, idade entre 18 e 30 anos, e que tinham ciclo menstrual irregular. O estudo foi realizado via internet através de formulários postados no Google Forms após consentimento livre esclarecido das participantes e aprovação pelo comitê de ética em pesquisa. Resultados. Sessenta e seis porcento das entrevistadas não estava inserida no mercado de trabalho. Observou-se que 76% se encontravam em peso adequado, 13% com sobrepeso e 11% com obesidade. Em relação à renda mensal bruta, 58% das estudantes relataram receber entre 1 e 3 salários-mínimos. Os alimentos de origem animal estavam sendo consumidos pelo menos duas a quatro vezes por semana; e aqueles que continham farinha de trigo como os pães e massas foram os mais utilizados. Os sintomas físicos frequentemente relatados durante a menstruação foram dores abdominais, cefaleia e constipação. Os sintomas emocionais mais expressados nesse período foram alterações de humor, irritabilidade e depressão. Conclusão. A menstruação causa grande interferência física e emocional em mulheres jovens na iminência de interferir no consumo dietético. Ressalta-se a importância de realizar orientações alimentares para prevenir deficiências nutricionais e minimizar os danos à saúde da mulher em fase reprodutiva, mesmo na presença de síndrome pré-menstrual.

Published: August 2023

Os ingressantes no curso de medicina trazem consigo substancial bagagem emocional advinda de experiências pessoais, familiares e sociais, dentre elas a tensão entre o excesso de opções desde a infância e a falta de decisão nas escolhas. O concorrido processo de seleção para a faculdade de medicina e a adaptação à universidade, numa fase em que o cérebro está em franco desenvolvimento, também impactam nas reações dos estudantes. Além disso, o próprio desenvolvimento no curso e a assumpção de postura profissional, com suas naturais exigências, podem gerar desequilíbrios psicossociais. Entre outros, os fatores acima contribuem para alta prevalência de estresse, ansiedade e depressão observados nos estudantes de medicina de todo o mundo. São revisados, neste artigo, os principais aspectos psicossociais presentes na rotina dos estudantes de medicina, com ênfase nos alunos brasileiros, e as relações destes com o raciocínio clínico, uma habilidade essencial a ser desenvolvida no futuro médico. Por fim, são sugeridas algumas ferramentas na tentativa de mitigar tais condições e ajudar os alunos na tomada de decisão.

A obesidade pode ser definida como uma Doença Crônica Não Transmissível, degenerativa com etiologia complexa e multifatorial, com interações epigenéticas, constituindo um relevante fator de risco para o desenvolvimento de outras comorbidades. Apesar da obesidade ser reconhecida como uma doença multifatorial e que requer cuidados intersetoriais e interdisciplinares, os tratamentos convencionalmente utilizados são unidisciplinares. Diante disso, o presente estudo teve por objetivo elaborar e implementar uma proposta interdisciplinar para o tratamento de adultos obesos usuários do SUS. A metodologia utilizada para essa pesquisa foi quantitativa de delineamento experimental não controlado o qual comparou diferentes indicadores de sujeitos que participaram de uma intervenção interdisciplinar em grupo, realizada em dois momentos distintos. O primeiro momento considerou a linha de partida e, o momento dois deu-se nove semanas após o término das ações desenvolvidas em cada grupo. Foi realizada a coleta de parâmetros antropométricos e bioquímicos antes e após a intervenção. Houve diminuição de 3,4 % do peso, 6,99 % da circunferência da cintura, 3,2% do índice de massa corporal, 5% da massa gorda relativa e 8,57% na relação cintura/ estatura, diferença estatisticamente significativa entre os parâmetros (p<0,001). A prevalência de Síndrome Metabólica (SM) encontrada na amostra foi de 61,66%, sendo que 25,9% das pessoas, deixaram de ter SM ao final da intervenção, com diferença estatística significativa (p=0,016). Os resultados encontrados apontam que a intervenção interdisciplinar em grupo apresentou resultados satisfatórios na mudança comportamental e nos parâmetros bioquímicos e metabólicos.

Published: August 2023

Este trabalho teve como objetivo realizar um estudo e desenvolvimento de simulações computacionais para previsão de perdas de cargas em dutos verticais e horizontais de petróleo em escoamento multifásico. A metodologia utilizada para análise de perdas de carga no escoamento de fluidos bifásico foi o modelo de correlação de Beggs e Brill (1973). A escolha dessa correlação se deu pelo fato de ser uma correlação genérica, e por isso, foi possível usá-la tanto para escoamento vertical quanto no escoamento horizontal ou inclinado.O desenvolvimento do algoritmo de solução para o modelo foi implementado através da plataforma científica e computacional scilab 6.1.0 a obtenção da distribuição da pressão ao longo do comprimento do duto ou da profundidade do poço vertical e a perda de carga de carga foi alcançada pelos cálculos dos gradientes, além disso, foram tabuladas pelo algoritmo as propriedades de massas específicas e viscosidade do óleo e do gás, respectivamente. Também foi executado no ambiente de programação octave 8.2 o mapa de regime de fluxo de Beggs e Brill por meio das fronteiras do escoamento.Os resultados obtidos a partir do modelo computacional foram apresentadas as curvas de perdas de pressão, o mapa de padrão de fluxo modificado indicando a classe de escoamento transição e as tabelas de propriedades dos fluidos, conforme os dados do poço obtidos da literatura e do duto de escoamento horizontal. Os resultados de perdas cargas e das propriedades dos fluidos utilizando o modelo de escoamento de Beggs e Brill para o escoamento vertical e em duto horizontal demonstraram comportamento satisfatório comparando-se as correlações de fator de atritos.

Mais que um projeto de extensão e uma atribuição profissional, o projeto Letras e Cores foi, pra mim, uma experiência de vida, motivada por questões pessoais e com resultados difíceis de mensurar, dado o tamanho e a diversidade das suas influências em aspectos profissionais, psíquicos e emocionais – meus e de 30 meninas. Aprovado pelo edital 14/2020 do Programa de Extensão Teresa de Benguela, o objetivo do Letras e Cores era capacitar meninas em situação de vulnerabilidade social nas técnicas de aquarela e lettering, voltadas à produção de quadros decorativos que pudessem ser revertidos em fonte de renda. Tratava-se, portanto, de uma formação artística pautada no empreendedorismo e no empoderamento feminino, que buscava oferecer às alunas condições de exercer, no futuro, uma atividade rentável, que propiciasse independência financeira e qualidade de vida. E aqui, neste capítulo, deixo um pouco de lado a formalidade científica e trago à tona toda a sensibilidade de Teresa de Benguela para relatar as dores e delícias emergidas na experiência deste projeto.

We report the discovery of a binary galaxy cluster merger via a search of the redMaPPer optical cluster catalog, with a projected separation of 535 kpc between the brightest cluster galaxies (BCGs). Archival XMM-Newton spectro-imaging reveals a gas peak between the BCGs, suggesting a recent pericenter passage. We conduct a galaxy redshift survey to quantify the line-of-sight velocity difference (153 ± 281 km s−1) between the two subclusters. We present weak-lensing mass maps from archival Hubble Space Telescope Advanced Camera for Surveys (HST/ACS) imaging, revealing masses of M

We draw from cosmological n-body simulations to find analog systems, which imply that this system is observed fairly soon (60–271 Myr) after pericenter, and that the subcluster separation vector is within 22° of the plane of the sky, making it suitable for an estimate of the dark matter scattering cross section.

Published: August 2023

In the course of evolution, animals and particularly insects, have developed efficient and complex mechanisms for survival. Biomimetics aims to find applications for these features of organisms (or organs) in industry, agriculture, and medicine. One of these features is the thin, flexible, and mobile insect ovipositor, which is also capable of carrying substances and drilling various substrates, usually of plant origin. Despite the well-studied structure of the ovipositor, the principles of its operation and real possibilities remain poorly understood. In our study, we first discovered an unusual behavioral pattern of oviposition of the female parasitoid Eupelmus messene Walker (Hymenoptera: Eupelmidae): she drilled with her ovipositor through the wall of a polystyrene Petri dish and laid her egg outside the dish. Due to the transparency of the plastic, we described the technique of ovipositor movement and studied its structure using scanning electron microscopy. Our research may contribute to developing minimally invasive guided probes and various other instruments.

Patulin, a known fungal poison, is an important pollutant in apples and products derived from apples and fodder. Ginger improved the liver function and prevents hepatotoxicity against many toxins and used in treatment of various diseases. The genetic toxicity of patulin in the liver of rats using the comet assay in vivo was investigated and effect of ginger (Zingibe officinale) on DNA damage induced by patulin. Five groups of adult male Sprague Dawley rats were used. The rats were given 3.75 mg kg-1 intraperitoneal (i.p) patulin. The rats were treated with ginger at a dose (100 mg kg-1) for four weeks and eight weeks. DNA damage was measured in the liver of rats using a standard genetic toxicity tests comet assay. Tail length and percentage of tail DNA within the comet increased significantly (p <0.05) in patulin group (p =0.01), (p =0.000) respectively, compared with control group a time-dependent manner, indicating an increase in DNA damage. The liver tissue showed signs of improvement in DNA damage after treating rats with ginger. In conclusion, these results indicate that patulin is genotoxic at the injected dose and that liver is an important target organ. Instead, ginger therapy can reduce DNA damage in liver cells from the toxicity caused by patulin.

The present study aims to evaluate the possibility of using low-cost adsorbents based on Cardoon waste for the depollution of industrial effluents. After characterization of the raw cardoon waste [1], the carbonization was carried out at 350 °C in a muffle furnace. In order to show the performance of the method used to prepare this activated carbon (PC), a comparative study with a commercial carbon (CC) is performed. The obtained activated carbon and the commercial carbon were characterized by thermogravimetric analysis, scanning electron microscopy coupled with EDX, X-ray diffraction, Fourier transform infrared absorption spectroscopy and inductively coupled plasma atomic emission spectroscopy. Approximate analyses of moisture content, volatile matter content, ash content and fixed carbon content, acid-base surface functions, pH at zero charge and iodine value were performed. The obtained results indicate that the main characteristics of the activated carbon prepared at 350 °C are practically similar to those of the commercial carbon; a homogeneous porous surface, an interesting percentage of carbon, a high thermal stability and a disorganized graphitic crystalline structure, the iodine adsorption values on the two carbons are 409.887 mg/g for PC and 430.191 mg/g for CC. The adsorption of methylene blue (MB) on both carbons was performed. The kinetics and isotherms of MB adsorption on the two carbons were evaluated. According to the obtained results, the use of the prepared carbon in effluent treatment can be put into perspective.

Authors: Louani Kahina , Kebiche Abdelkader
Published: August 2023

La croissance urbaine accélérée et les mutations socio-économiques qu’a subies la ville de Tizi Ouzou, génèrent de plus en plus l’évolution des demandes en déplacement, en transport et en infrastructures routières, avec une situation marquée par la dominance du caractère rural et des contraintes topographiques qui produisent des obstacles vis-à-vis du développement urbain de cette région. On s'appuie dans cette étude sur la notion d'interaction "urbanisme-mobilité", dans un contexte marqué par une urbanisation spontanée et par un système de transport insuffisant qui ne serait pas susceptible de satisfaire la demande de la population. Mais plusieurs atouts sont favorables pour une meilleure gestion de la mobilité durable à Tizi Ouzou où la part modale du transport collectif est la plus dominante et les taux de motorisation sont encore faibles.

Published: August 2023

The objective of this paper is to construct periodic life tables based on the mortality experience of the Algerian survivor pension beneficiaries. Usually, the mortality of retirees is lower than that of the global population, essentially due to better living conditions and access to health care. Also, we aim to verify if mortality is different between the categories of survivor pensioners and to adapt the actuarial life tables accordingly, which may result in actuarial valuations more adapted to the risk function of each subpopulation. To this end, we compare three parametric models i.e., the Gompertz model, the Kannisto model, and the Heligman & Pollard model. Results show a significant difference between the life expectancy of the survivor pension beneficiaries and that of the direct retirees and between the categories of survivor pensioners.
Assessment of algerian interbank interest rate through extreme value theory
Authors: Afroune Nadia , Achouche Mohamed
Published: August 2023

This article tries to examine the evolution of interest rates in the Algerian interbank money market which focuses on the behavior of extreme. Empirical results illustrate that data are not distributed normally, exhibiting that their distribution is fat tails. Applying the GEV method on the maxima shows that the distribution law of the maxima changes over time due to the non-stationary data.  Subsequent investigations suggest two subsample periods.   The first period characterized by a deterioration of the liquidity of Algerian banks following the collapse of oil prices (1997-2000), the distribution law obtained is the law of Fréchet, but during the period characterized by an excess liquidity of the banks resulted from the increase in oil prices (2002-2013), the distribution law found is that of Weibull which is right bounded.
Déterminants de la performance à l’export des pme algériennes : dirigeant, entreprise et conditions dans le pays d’origine
Authors: Kadi Mohamed , Cheriet Foued
Published: August 2023

Ce travail a pour objectif d’analyser les déterminants de la performance à l’export des PME en intégrant les caractéristiques du dirigeant, de l’entreprise et de l’environnement externe, comme les éléments du contexte du pays de départ et les stimuli à l’export. En nous basant sur des données recueillies auprès de 53 PME exportatrices algériennes, et à travers un modèle d’équations structurelles, nous avons testé les effets de trois groupes de facteurs (profil du dirigeant, caractéristiques internes de l’entreprise, caractéristiques de l’environnement externe) sur deux types de mesures de la performance (objective et subjective). Nos résultats montrent l’importance des facteurs liés au profil du dirigeant et confortent une conception multidimensionnelle de la performance à l’export.
Perceptions of the sustainable entrepreneurial intention of university students as picture for economic integration
Authors: Boudia Mouhamed Fouzi , Hagain Faouzia
Published: August 2023

The domain of sustainable entrepreneurship has recently received great interest by many researchers, and this is due to the role it plays in sustainable economic development. Algeria has adopted a series of policies and programs to promote sustainable enterprises. Its success is linked to the awareness of emerging and potential entrepreneurs, particularly the contribution of the university in training and developing graduates, considered as the elite of the society. This research paper aims to measure the impact of personal perceptions of sustainable entrepreneurship on the intent of sustainable entrepreneurship. The study was conducted on a group of students who are about to graduate. The sample contained eighty-three (83) students from various disciplines of the university. It concluded that the perceptions of sustainable entrepreneurship have an impact on sustainable entrepreneurial intentions and that both the social and the environmental perceptions have a positive and statistically significant impact on sustainable entrepreneurial intention. However, the economic perception did not have a significant effect on the intention of sustainable enterprise.
Contribution of small rodent communities (Muridae) to the history of West Central African savannas (case of Gabonese savannas): diversity, biogeographic affinities, phylogeography and paleoenvironmental analyses
Authors: Mboumba Jean-François , Guyot Véronique
Published: August 2023

Savannas of West Central Africa stand around or inside the large rainforest block. They result from paleo-climatic fluctuations, but the  details of their history remain poorly known. The aim of the present study is to explain the present distribution of savannas in West  Central Africa, considering the two classic anthropic or paleoclimatic hypotheses about their origin. The study was focused on Gabonese  savannas and based on small terrestrial mammal patterns. The phylogeography of small species of strictly savanicolous rodents was compared using nested clade analysis of haplotype networks based on cytochrome b mitochondrial DNA, coupled with other approaches.  The data were also compared with literature data on vegetation changes in tropical West Africa over the last 150,000 years  to test scenarios on the origin and history of Gabonese savannas. The results showed several fragmentation events of small rodent  populations and revealed redundant biogeographic relationships. These events were dated, and the results about the history of rodent  species were congruent with palaeobiological data about the successive phases of savanna expansion and fragmentation: the results  support the hypothesis of a paleoclimatic origin of the Western Congolian forest-savanna mosaic. These rodent population  fragmentation events occurred more than 50,000 years ago.

L’Afrique de l’Ouest subsaharienne a un cadre physionomique privilégié pour la conservation des Poaceae (Gramineae). Cependant, la  détermination des centres de diversité spécifique des Poaceae a été très peu abordée dans les travaux scientifiques. La présente étude  avait pour objectif de cartographier les centres de diversité des Poaceae en Afrique de l’Ouest. Elle a donc nécessité la collecte de  données d’occurrence sur GBIF et dans le Parc national de la Comoé. Au total, 134127 spécimens de Poaceae concernant l’Afrique de  l’Ouest, regroupé en 116 genres et 402 espèces ont été considérés. La zone d’étude a été subdivisée en 506 mailles suivant une  résolution spatiale d’une maille de 1.5 x1.5 de côté pour analyser la distribution spatiale de la richesse spécifique. Les résultats montrent  que certaines zones comme le nord du Burkina Faso ont été bien échantillonnées par contre d’autres comme le nord-est du Mali ne l’ont  pas été. Aussi, la richesse spécifique des différentes grilles croît de la marge sud du Sahara à la latitude 10oN ; puis de la latitude 5oN au  niveau du golfe de Guinée à la latitude 10oN. Cette diversité est aussi variable de l’est à l’ouest. La carte de distribution spatiale de  l’ensemble des échantillons a mis en évidence les centres de diversités des Poaceae d’Afrique de l’Ouest. 

 

English title: Diversity of West African Poaceae, with emphasis on determining centers of diversity for their conservation

Sub-Saharan West Africa has a privileged physiognomic framework for the conservation of Poaceae (Gramineae). However, few studies  addressing the aspect of determining the centers of specific diversity of this taxon have been published. this present study aimed at  maping the centers of diversity of Poaceae in West Africa. The study therefore required the collection of occurrence data on GBIF and in  the Comoé National Park in Côte d’Ivoire. In total, 134127 specimens of Poaceae of West Africa, grouped into 116 genera and 402 species  were considered. The study area was subdivided into 506 grids according to a spatial resolution of a grid of 1.5 x1.5 on a side to analyze  the spatial distribution of species richness. The results show that certain areas such as northern Burkina Faso were well sampled, while  others such as northeastern Mali were not. Also, the specific richness of the different grids increases from the southern margin of the  Sahara to latitude 10oN; then from latitude 5oN at the level of the Gulf of Guinea to latitude 10oN. This diversity is also variable from east  to west. The spatial distribution map of all specimens revealed the centres of diversity of the West Africa Poaceae.

On Provable White-Box Security in the Strong Incompressibility Model
Authors: Alpirez Bock Estuardo , Brzuska Chris , Lai Russell W. F.
Published: August 2023

Incompressibility is a popular security notion for white-box cryptography and captures that a large encryption program cannot be compressed without losing functionality. Fouque, Karpman, Kirchner and Minaud (FKKM) defined strong incompressibility, where a compressed program should not even help to distinguish encryptions of two messages of equal length. Equivalently, the notion can be phrased as indistinguishability under chosen-plaintext attacks and key-leakage (LK-IND-CPA), where the leakage rate is high.In this paper, we show that LK-IND-CPA security with superlogarithmic-length leakage, and thus strong incompressibility, cannot be proven under standard (i.e. single-stage) assumptions, if the encryption scheme is key-fixing, i.e. a polynomial number of message-ciphertext pairs uniquely determine the key with high probability. Our impossibility result refutes a claim by FKKM that their big-key generation mechanism achieves strong incompressibility when combined with any PRG or any conventional encryption scheme, since the claim is not true for encryption schemes which are key-fixing (or for PRGs which are injective). In particular, we prove that the cipher block chaining (CBC) block cipher mode is key-fixing when modelling the cipher as a truly random permutation for each key. Subsequent to and inspired by our work, FKKM prove that their original big-key generation mechanism can be combined with a random oracle into an LK-IND-CPA-secure encryption scheme, circumventing the impossibility result by the use of an idealised model.Along the way, our work also helps clarifying the relations between incompressible white-box cryptography, big-key symmetric encryption, and general leakage resilient cryptography, and their limitations.
