An Empirical Study of Relationship between Working Capital Management and Leverage in Selected Petroleum Companies in India
Authors: Nayyef Yousif Hameed
Published: May 2023

The main purpose of this article is to find out the relationship between working capital management and leverage of selected petroleum companies in India. The management of working capital and leverage in the business organization has been considered as very crucial part in financial management. Working capital considered as surplus of current assets over current liabilities and leverage considered as firm’s ability of employing long term fund having a fixed cost for the purpose of increasing the return of the real owner of the organization. The evaluation of relationship between the two variables and it is identified with the help of parametric test like correlation analysis and one-way ANOVA.  The major findings of the study indicated that there is mixed relationship between working capital and leverage position because with the help of correlation analysis Reliance Petroleum, ONGC (Oil and Nature Gas Corporation Limited), IOCL (Indian Oil Corporation Limited), BPCL (Bharat Petroleum Corporation Limited) indicated positive relationship between two variables. GAIL (Gas Authority of India Limited) indicated negative relationship between working capital and leverage during the study period.
Des corps perdus aux corps-bateaux. L’Art et la manière
Authors: Fortier Corinne
Published: May 2023

The sunken ship motif is frequently found in films and artistic installations on migrants, as it symbolizes their perilous crossing. As Michel Foucault asserts, the ship is “the heterotopia par excellence,” and the contemporary fate of migrant barges is quite comparable to that of the ship of fools described by the philosopher in the classical age. The ship is a heterotopic motif which acts as a physical substitute for the body of the castaway, a substitute that makes sense in the maritime world, and that we find in classical paintings, in popular religious art, or even in the ex-votos. The objects that belonged to migrants perished at sea have a memorial character, allowing their history and sometimes their identity somehow to be restored. Giving them back their name is an essential issue so that they can be buried and not wander in a heterotopic space after their death, a heterotopic wandering which also characterizes the experience of their migratory journey.
Hétérotopies domestiques
Authors: Arambašin Nella
Published: May 2023

In applying the notion of heterotopia to domesticity this paper aims to historicize, from the 19th century to today, the vanishing points imagined by those who maintain the interiors where they are assigned to those “good to do everything,” such as nannies and housewives. The inner frame then opens like an Alberti’s window to narrative perspectives which, according to historical configurations, articulate private and public spaces, as well as urban and rural, bourgeois and popular, and national and foreign, to designate counter-spaces of domesticity: the café, ball, square, multimedia installation, beach, and flight. To access the paradoxical nature of these “located utopias,” both hindered and half-open to freedom, it is necessary to use the writers (Octave Mirbeau, Marguerite Duras, Léïla Slimani, Aldous Huxley), artists (Edouard Manet, Lucien Simon, Richard Hamilton, Birgit Jürgenssen), as well as filmmakers (Benoît Jacquot, Alfonso Cuarón). They lay the groundwork for a deconstruction of the matrimonial norm, from which feminine vanishing points radiate, produced by the stereotypes of the servant-whore, the good Bécassine or the housewife, in order to try to thwart them and free themselves from them.
Les hétérotopies perturbatrices
Authors: Zandieh Rezvan
Published: May 2023

Since Menstruationsfilm (1966-67), the pivotal work of Valie Export, many contemporary artistic creations highlight the menstrual value of “gendered blood,” to use the term of Mary Jane Lupton in Menstruation and Psychoanalysis (1993: 3). In the form of painting, performance, installation and video, these creations apply “menstrual blood” in a feminist context, as was the case with the first works made with this type of blood. This article will focus on the crucial link between these works and the concept of heterotopia. On the one hand, we will show in what sense these works can constitute heterotopias and/or how they integrate this concept of by their subversive dimension. On the other hand, we will seek to understand how these works contribute to the extension of heterotopias, both in mental spaces, than in those of the real in our time
Experimental science-fiction films as filmic heterotopia
Authors: Holloway Mathilda
Published: May 2023

This paper questions the concept of the possible heterotopia of cinema by making a creative reading of a corpus of contemporary experimental science-fiction films. We think heterotopia in direct relation to utopia. If utopia can be linked to a form of thought, then heterotopia would be a form of realised or achievable utopia. Heterotopian action would then allow us to experiment subversive, if not new social configurations, where utopian thought allows us to dream of better (or at least other) societies. We propose to look at these issues starting from experimental science-fiction films. The aesthetic and narrative resorts as well as the modes of production of works like Slow Action and Urth by Ben Rivers, Meteor by Mathias Müller and Christoph Girardet, Momoko Seto’s Planet Series or Jérôme Cognet’s Guerilla Hubble, indeed offer us with an audiovisual experience that invites us to re-evaluate our human relation to the world by appealing to our capacity for imagination and by stimulating our free will, notably through their staging of historicity and multiplicity.
La dystopie W pour dire l’horreur des camps de concentration. Une étude sur les hétérotopies de Perec
Authors: Holmertz Samuel
Published: May 2023

In the work of Georges Perec, the novel W or the Memory of Childhood (1975) is an attempt, halfway between autobiography and detective novel, to reveal the greatest enigma of the existence of the writer, namely the tragic fate of his mother who was deported to Auschwitz from where she would never return. In order to be able to outline the ignominy of the concentration camps, Perec refers to a story that he himself had invented during his childhood: one on the island of W. Based on the Olympic ideal, its residents are athletes who must endure a series of inhuman challenges. The monstrous dystopia of the Island of W thus echoes the historical facts of the Second World War, which directly affected Perec, although he did not witness them in person. In the perspective of a study of the island of W, the concept of heterotopia forged by Michel Foucault will set the theoretical perspective for this work. This article will also analyze how the places – both the spaces of the everyday life and heterotopias, other spaces which very often play an allegorical role (Ellis Island, to which Perec dedicated a book, is also an example), as the island of W does – occupy a prominent place in Perec’s works. This stresses out the metonymic power generated by the creation of spaces, whether entirely invented or borrowed from reality, since they always tell something other than merely showcase themselves and install a mirror game between fiction and reality.
TD 2872 - Avaliação dos condicionantes de abandono contratual e viabilidade econômica da relicitação em concessões de infraestrutura pela abordagem das opções reais
Authors: Costa Felipe Amaral
Published: May 2023

O objetivo do estudo é apresentar um modelo, a partir da aplicação da Teoria das Opções Reais (TOR), para o aprimoramento regulatório da metodologia de cálculo de indenizações relativas aos investimentos em bens reversíveis em caso de extinção antecipada de concessões rodoviárias por meio de devolução amigável (Lei no 13.448/2017), buscando-se chegar ao seu “justo valor”. Para tanto, uma série de análises de sensibilidades foi realizada para aquelas variáveis que exercem maior influência no comportamento da opção. Além disso, avaliou-se a sua dinâmica em diferentes arranjos contratuais, modalidades de leilão e métodos de quantificação de indenização e precificação de opções. Por meio da análise de sensibilidade, majorando as cifras reembolsáveis, evidenciou-se a tendência de alta no valor da opção, na probabilidade de exercício e no contingenciamento necessário para as verbas indenizatórias. O estímulo à adoção de estratégias hiperagressivas por parte dos licitantes também é uma possível consequência adversa que se pode ter com a flexibilização das hipóteses para o término dos contratos, caso lhes seja assegurada a garantia de retorno sobre parte dos investimentos realizados. O trabalho demonstrou que a opção de abandono é sensivelmente afetada pelo desconto aplicado à tarifa base do leilão: quanto maior o deságio, mais valiosa se torna a opção e mais certa é a extinção prematura do contrato.

Hernia registry as the first stage of the development of a ‘learning healthcare system'
Authors: Kravchenko A. Yu. , Kakotkin V. V. , Agapov M. A.
Published: May 2023

This paper aims to assess the effectiveness of current approaches to information exchange among key actors in the healthcare system and their impact on healthcare delivery. Specifically, it compares existing approaches to collecting medical data in herniology and explores their potential use in ‘learning healthcare systems'. However, current nosological registries do not fully meet the needs of these systems. One solution is to modify medical information systems to serve as a source of medical data of sufficient quality to supplement existing medical data lakes. Achieving this requires collaboration among clinicians, researchers, medical information system engineers, and data scientists. Establishing legal regulations for the transfer of medical data to scientific and educational organizations is necessary to fully realize the potential of this new type of nosological registry for advancing science and medicine.
Reconstruction methods after proximal gastrectomy for cancer
Authors: Komarov R. N. , Osminin S. V. , Novikov S. S. , Bilyalov I. R.
Published: May 2023

The study on gastrointestinal tract reconstruction after proximal gastrectomy (PG) for stomach cancer aimed to identify the most optimal way to restore the integrity of the gastrointestinal tract. The study involved a comparative analysis of 23 papers with a total of 1,517 cases of reconstructions after PG from four countries during the period 2010—2021. The five most commonly described types of reconstruction after PG were analyzed: jejunal interposition, esophagogastric anastomosis, ‘double tract' reconstruction, ‘double flap' reconstruction, and jejunal pouch interposition. The comparison criteria included the duration of surgeries, intraoperative blood loss, length of hospital stay, as well as postoperative complications such as anastomotic leakage, anastomotic stricture, reflux esophagitis, and residual food. The results of the study can provide valuable insights for surgeons in choosing the most optimal type of reconstruction after PG, thus reducing the risk of postoperative complications and improving the quality of life of patients with stomach cancer.
Treating unresectable intrahepatic cholangiocarcinoma with transarterial chemoembolization and an unusual progression with cardiac involvement
Authors: Mumdzhiev Nikola , Borisov Borislav , Tenev Rumen , Radicheva Mariana
Published: May 2023

Intrahepatic cholangiocarcinoma is a rare type of cancer that is usually discovered at an advanced stage where surgical treatment is not an option. When compared to standard systemic therapy, transarterial chemoembolization (TACE) can provide a survival benefit to unresectable patients. Extrahepatic tumor spread is not rare, but cardiac involvement is an unusual complication.

We present the case of a 56-year-old man with histologically proven intrahepatic cholangiocarcinoma. Oncologic risk factors include hepatitis B and liver cirrhosis. Being in an unresectable stage of the disease, three TACE procedures were performed. Partial response was achieved (according to RECIST) leading to a 16-month survival. However, disease progression was present, with unusual heart metastases.

TACE can bring a survival benefit to unresectable cholangiocarcinoma patients. Defining the best disease stages in which TACE can be implemented and introducing it as part of standard treatment guidelines still presents a challenge.
Cardiac echinococcosis, a multidisciplinary approach in the diagnosis and treatment of this rare entity: two case reports and literature review
Authors: Kelchev Assen , Kunev Boyan , Partenova Anelia , Genova Kamelia , Nikolov Dimitar
Published: May 2023

We present two case reports of cardiac echinococcosis. Case 1 was a 33-year-old woman with hepatic and cardiac echinococcosis. The parasitic cyst was located intramyocardially in the free wall of the left ventricle leading to cranial dislocation of the left circumflex coronary artery (LCx). The patient was successfully operated. Case 2 was a 28-year-old woman with hepatic and cardiac echinococcosis. The parasitic cyst was located in the left ventricular myocardium in the area of the apex and manifested clinically as paroxysms of ventricular tachycardia. The ultrasound study showed a 3.2×2.8 cm cyst dislocating the papillary muscles and causing moderate mitral regurgitation.

Bulgaria ranks first in the European Union in terms of the number of echinococcosis patients. Although cardiac involvement is uncommon, occurring in only 0.5%–2% of cases, it can cause a wide range of clinical symptoms. Multimodal imaging is a key step in the management of patients with cardiac involvement.
Confiner la menace
Authors: Flame Éric
Published: May 2023

L’auteur se réfère au récit La Métamorphose de Franz Kafka comme un récit de transformation, celle des mutations pubertaires où s’entremêlent l’émergence de la sexualité génitale, l’assujettissement du corps au biologique et la permanence du sexuel infantile. Usuellement le fantasme d’auto-engendrement permet d’articuler ces différentes contraintes. L’échec de cette articulation entraîne chez les adolescent(e)s un vécu d’un corps incontrôlable et menaçant qu’il s’agit de maintenir confiné.
De la claustration à la fugue ou « le complexe d’Alexis »
Authors: Assoun Paul-Laurent
Published: May 2023

La tendance à se reclure dans l’espace familial est une tendance manifeste de l’adolescence. La sortie de l’enfance, avec la « décroyance parentale », se marque par une claustration hostile dans l’enclos de « sa » chambre, au moins jusqu’à l’acte de « déclaustration » soudaine. Le cas d’Alexis, l’un des premiers saints, mérite de baptiser un « complexe » comme paradigme clinique : trouvant le moyen de s’incruster incognito dans la maison du père et menant une double vie, après avait cherché hors des idéaux familiaux un Ailleurs salutaire. Comment ne pas y reconnaître un fantasme majeur de l’adolescence, comme le confirmera le récit kafkaïen de la « Métamorphose » ? Il est troublant de le retrouver, au-delà du temps et des cultures, dans le phénomène nommé Hikikomori – « auto-séquestration » des adolescents japonais – réduit à un syndrome, alors qu’il s’éclaire du drame inconscient ici reconstitué.
Masochisme et mélancolie, l’enfermement de Madame Butterfly
Authors: Verdon Benoît , Louët Estelle , de Luca Manuella , Chabert Catherine
Published: May 2023

Madame Butterfly , opéra de Puccini, est une illustration magistrale du masochisme et de la mélancolie mobilisés dans les conduites sacrificielles sous-tendant la claustration à l’adolescence. Les auteurs montrent combien derrière la figure de la femme passive et naïve se révèle une position active de Butterfly pour lutter contre la séparation. Les identifications mélancoliques au père déchu et suicidé nourrissent l’impossibilité de renoncer à l’objet perdu et de gagner en liberté autrement qu’en s’attaquant soi-même.

Nous illustrons enfin notre propos avec une vignette clinique, ouvrant sur la question de la fonction de miroir.
A partir du monastère : essais d’ouverture
Authors: Celnikier Sarah
Published: May 2023

À l’âge où beaucoup s’aventurent hors de la famille, d’autres adolescents, reclus et déscolarisés, adoptent une attitude monacale, au point que la langue les dise « cloîtrés » dans leur chambre. À leur insu, et sous différentes formes, quelque chose du registre religieux fait retour dans la clinique de ces jeunes. Leur renoncement à la sexualité et leur refus du monde extérieur, dont ils ne veulent rien savoir, réalisent un idéal de pureté – difficilement perméable au lien, fût-il thérapeutique.

Chargé de contrôler les privations de liberté subies en « zone d’attente » par les personnes étrangères auxquelles l’accès au territoire est refusé, le juge judiciaire exerce sa mission dans un cadre légal restrictif et des conditions matérielles dégradées qui en affectent lourdement l’efficacité. À ces contraintes s’ajoutent parfois des comportements inacceptables traduisant la perméabilité de certains juges à une xénophobie ambiante.

Une révolution bureaucratique avortée. Les énarques et l’État au Mali
Authors: Baczko Adam , Dorronsoro Gilles
Published: May 2023

A contrario de la thèse d’une fonction publique « introuvable », les énarques maliens donnent à voir un corps doté d’un « intérêt au dés intéressement ». L’établissement de l’Ena (École nationale d’administration) résulte d’une coalition entre hauts fonctionnaires et quelques hommes politiques confrontés à un effondrement des institutions. Un concours méritocratique, une formation exigeante et un statut avantageux ont favorisé des profils issus des classes populaires et moyennes, qui ont connu une rapide ascension au sein de l’administration. Mais cette révolution bureaucratique a avorté face aux résistances dans la fonction publique et la classe politique.
Transition sécuritaire et production « bric-à-brac » de l’ordre post-guerre en Côte d’Ivoire
Authors: Zina Ousmane
Published: May 2023

En 2017, une vague de mutineries secouait la Côte d’Ivoire, interrogeant la capacité du pays à reconstruire une armée divisée après le conflit armé post-électoral de 2010-2011. Ces événements ont laissé entrevoir une confrontation d’intérêts divergents et un entrecroisement de réseaux d’acteurs à la fois formels et informels dans le champ de cette reconstruction du dispositif sécuritaire ivoirien. C’est en partant de ce constat que l’article défend le postulat selon lequel une politique de reconstruction sécuritaire « bric-à-brac » aurait été mise en œuvre depuis la fin de la crise post-électorale. Il en analyse la signification, la portée et les limites. Le texte s’appuie sur le cadre théorique de la sociologie de l’action publique en contextes africains, et saisit dans le temps long les relations de pouvoir, les registres de domination, les ruptures et les continuités pour expliquer ce moment de fabrique d’un nouvel ordre sécuritaire post-guerre en Côte d’Ivoire.
Industries minières et violences au Burkina Faso. Comment le développement minier a-t-il contribué à l’expansion des groupes armés ?
Authors: Hubert Nicolas
Published: May 2023

Dans cet article, nous nous interrogeons sur la manière dont le développement de l’industrie extractive a contribué à la propagation des violences et des dynamiques conflictuelles au Burkina Faso. Pour mieux saisir ces dynamiques, nous nous intéressons à la manière dont les groupes armés transnationaux actifs au Sahel, concurrençant l’autorité centrale des États, s’appuient sur les griefs des populations pour élargir leurs bassins de recrutement et favoriser leur intégration sociale et territoriale. Nous analysons également les liens entre ressources naturelles et conflits armés, puis le processus de rupture avec l’autorité centrale, avant d’appréhender directement l’élargissement des bassins de recrutement des groupes armés dans la région burkinabè du Sahel.
Fable primitiviste. À propos de l’exposition « Sur la route des chefferies »
Authors: Beuvier Franck
Published: May 2023

Cette chronique de l’exposition « Sur la route des chefferies du Cameroun » présentée en 2022 au musée du quai Branly-Jacques Chirac, pointe les dérives d’un récit identitaire. À la manière d’un voyage d’immersion, les promoteurs de l’événement proposent une visite initiatique de la chefferie bamiléké, où le public découvre tour à tour un large éventail de croyances totémiques au fondement de la vie religieuse et morale, une théosophie de la nature confondue avec la mythologie bamiléké, un régime politique équilibrant monarchie et démocratie, et une organisation sociale conforme au principe d’égalité entre hommes et femmes. Composé de vrais-faux coutumiers convertis en totems et en fétiches, l’héritage donné à voir au fil du parcours est justifié au nom d’une tradition séculaire, combinant habilement caractères primitivistes et tendances de notre temps. Les concepteurs camerounais ont ainsi misé sur l’animisme écologique pour séduire bailleurs de fonds et visiteurs, aux dépens de l’histoire et de l’élan décolonial.

Critical Thinking Disposition and Influencing Factors Among New Graduate Nurses
Authors: Wu Hsiao-Ling , Lu Der-Fa , Tsay Pei-Kwei
Published: May 2023

Background:

Critical thinking disposition is important to facilitate professional judgment for novice nurses. The goals of this study were to describe critical thinking disposition among newly graduated nurses and to examine the factors that impact the development of critical thinking disposition.

Method:

This study employed a cross-sectional research design.

Results:

The mean critical thinking score was 244.11 (
SD
= 44.70), with the highest mean scores earned on the inquisitiveness subscale (
M
= 38.46,
SD
= 7.10). The lowest subscale scores were for systematicity (
M
= 34.81,
SD
= 5.54), truth seeking (
M
= 33.12,
SD
= 6.42), and self-confidence (
M
= 29.26,
SD
= 6.90). Critical thinking dispositions were significantly associated with teaching strategies during the educational period, problem-based learning courses, and length of exposure to problem-based learning.

Conclusion:

Findings provide information to understand the disposition toward critical thinking in novice nurses and can serve as a reference in efforts to improve novice nurses' critical thinking skills.

Certain differential subordination results for univalent functions associated with $ q $-Salagean operators
Authors: Amini Ebrahim , Fardi Mojtaba , Al-Omari Shrideh , Saadeh Rania
Published: May 2023

In this paper, we employ the concept of the $ q $-derivative to derive certain differential and integral operators, $ D_{q, \lambda}^{n} $ and $ I_{q, \lambda}^{n} $, resp., to generalize the class of Salagean operators over the set of univalent functions. By means of the new operators, we establish the subclasses $ M^n_{q, \lambda} $ and $ D^n_{q, \lambda} $ of analytic functions on an open unit disc. Further, we study coefficient inequalities for each function in the given classes. Over and above, we derive some properties and characteristics of the set of differential subordinations by following specific techniques. In addition, we study the general properties of $ D_{q, \lambda}^{n} $ and $ I_{q, \lambda}^{n} $ and obtain some interesting differential subordination results. Several results are also derived in some details.
Estrategias habitacionales de mujeres venezolanas en Chile. Obstáculos, desafíos y resistencias
Authors: Zenteno Torres Elizabeth , Contreras Hernández Paola , Trujillo Cristoffanini Macarena
Published: May 2023

El fenómeno migratorio en Chile ha presentado patrones cambiantes durante los últimos años. Focalizado especialmente en la migración proveniente desde Venezuela, el presente artículo tiene por objetivo comprender el proceso de búsqueda y asentamiento residencial de mujeres venezolanas en Chile. Para ello se realizaron entrevistas cualitativas en Valparaíso y Viña del Mar, a través de las cuales se recabaron las principales dificultades que ellas deben atravesar para acceder a la vivienda, que se transforman en imbricados procesos de racialización y feminización. Sin embargo, también se evidenció la existencia de múltiples estrategias de agenciamiento desplegadas para la obtención de un lugar donde vivir y cuidar de sus familias. Así, y desde un enfoque interseccional que comprende los estudios urbanos, raciales y de género, se concluye que, si bien las mujeres venezolanas migrantes deben enfrentarse a contextos de discriminación y segregación en la búsqueda de vivienda, también establecen mecanismos colaborativos que permiten su acceso, tales como el allegamiento, la cohabitación, la gestión compartida y la creación de redes.
EFFECTIVENESS OF LEARNING RATE IN DEMENTIA SEVERITY PREDICTION USING VGG16
Authors: Torghabeh Farhad Abedinzadeh , Modaresnia Yeganeh , Khalilzadeh Mohammad Mahdi
Published: May 2023

Alzheimer’s disease (AD) is the leading worldwide cause of dementia. It is a common brain disorder that significantly impacts daily life and slowly progresses from moderate to severe. Due to inaccuracy, lack of sensitivity, and imprecision, existing classification techniques are not yet a standard clinical approach. This paper proposes utilizing the Convolutional Neural Network (CNN) architecture to classify AD based on MRI images. Our primary objective is to use the capabilities of pre-trained CNNs to classify and predict dementia severity and to serve as an effective decision support system for physicians in predicting the severity of AD based on the degree of dementia. The standard Kaggle dataset is used to train and evaluate the classification model of dementia. Synthetic Minority Oversampling Technique (SMOTE) tackles the primary problem with the dataset, which is a disparity across classes. VGGNet16 with ReduceLROnPlateau is fine-tuned and assessed using testing data consisting of four stages of dementia and achieves an overall accuracy of 98.61% and a specificity of 99% for a multiclass classification, which is superior to current approaches. By selecting appropriate Initial Learning Rate (ILR) and scheduling it during the training phase, the proposed method has the benefit of causing the model to converge on local optimums with better performance.
What social determinants will cause ethical challenges in geriatric care? Comments from South Africa
Authors: Lategan Laetus , Van Zyl Gert , Kruger Willem
Published: May 2023

Background: Social determinants are defined as those nonmedical factors that influence health. Their influence is especially evident in vulnerable communities, such as the geriatric one. However, which social determinants will cause ethical challenges in geriatric healthcare in South Africa are not yet confirmed.Objective: This study first identified which social determinants influence geriatric care. The study then established which of these social determinants raises ethical challenges in geriatric care. Methods: Twenty statements were identified from the literature review and were grouped into 3 indexes, focusing respectively on i) a general view on public health and social determinants; ii) social determinants influencing geriatric people’s health; iii) the consequences of social determinants on geriatric people’s health. The rating was based on presenting the statements employing a 5- point Likert scale.Results: The rating of statements confirmed the generally accepted view that social determinants impact geriatric people’s health. The responses to the statements were an additional confirmation that the quality and access to healthcare services influence geriatric care and lead to ethical challenges. Matters such as corruption, limited resources, and the COVID-19 pandemic contribute to the influence of social determinants and the expected but failed ethical behavior toward the geriatric community. Conclusion: The geriatric community is vulnerable because of the ongoing social factors that have a negative impact on health, of which healthcare quality and provision are significant contributing factors. These factors contribute to ethical challenges in healthcare for the geriatric community.
Potential of bio-drying applied to exhausted grape marc
Authors: Rada Elena Cristina , Ragazzi Marco
Published: May 2023

In the present work, experimentation was carried out to study the behavior of exhausted grape marc during the bio-drying process. This process was chosen as an alternative to the typical grape marc thermal drying approach. The aim was to reduce the moisture level thanks to the biological exothermal reactions, and to increase the energy content in the biodried grape marc. The target was the generation of a product interesting for energy options. For the development of the research, a biological pilot reactor and a respirometric apparatus were used. Results demonstrated that bio-drying can decrease the water content saving the original energy content. The final material could be assumed like a solid recovered fuel, class 5:1:1 with a very low potential rate of microbial self-heating.
Evaluating the correlation between chemical and sensory compounds in Blaufränkisch and Cabernet Franc wines
Authors: Balga Irina , Kiss Attila , Gál Lajos , Leskó Annamária , Kállay Miklós
Published: May 2023

The positive physiological effects of the bioactive compounds of red wines have been known for a long time. Besides that, the polyphenolic compounds of red wines represent one of the most important factors for oenology. With a special chemical analysis, we discover the relationship between chemical and sensory compounds. In this way, we explore which compounds influence sensory properties. The phenolic compounds are the quality attributes of the wine. The analysis of phenolic compounds was carried out in two red wines: Cabernet Franc and Blaufränkisch. The aim of this study was to analyse the chemical and organoleptic characteristics of these two wines and evaluate the connection between the two parameters. In addition, we also examined the influence of the polyphenolic content on sensory perception. The experiment was carried out in a cool climate wine region in Eger, Hungary, in vintage of 2008. We investigated the profile of phenolic contents in new and aged wines. Total polyphenolic content, anthocyanin, leucoanthocyanin and catechin were evaluated by spectrophotometer. Stilbenes were identified and quantified by high-performance liquid chromatography.
Amino acid content in red wines obtained from grapevine nitrogen foliar treatments: consumption during the alcoholic fermentation
Authors: Portu Javier , López Rosa , López-Alfaro Isabel , González-Arenzana Lucía , Santamaría Pilar , Garde-Cerdán Teresa
Published: May 2023

Nitrogen is an important element for grapevine and winemaking which affects the development of the plant and yeast, and therefore it is important for wine quality. The aim of this work was to study the influence of foliar application to vineyard of proline, phenylalanine and urea and two commercial nitrogen fertilizers, without and with amino acids in their formulation, on the wine amino acid content and their consumption during the alcoholic fermentation. The results showed that these treatments did not affect the amino acid composition in wines. The differences observed for certain amino acids were so small that the concentration of total amino acids was not significantly different among wines. Moreover, it was observed that the higher the content of amino acids in the medium, the greater their consumption during the alcoholic fermentation.

The aim of this work was to evaluate the potential of moderate consumption of red wine to modulate the intestinal inflammation response on healthy humans. Fecal samples from a human intervention study (n=34) were collected before and after consumption of red wine for 4 weeks, and 24 immune markers including immunoglobulins, cytokines, chemokines and growth factors, were analysed. When considering the whole group of case volunteers, almost no statistically significant differences were found in the immune markers after wine consumption. However, a detailed exploration of the values differentiated a 6-volunteer subgroup that showed unusually high values of cytokines before wine consumption. For this subgroup, wine consumption significantly reduced the content of 16 out of 24 markers down to usual values, especially noticeable for cytokines related to the promotion of initial inflammation (tumor necrosis factor-alpha, interleukin 6 and interferon-gamma). This study reveals, for the first time, changes in the fecal profile of inflammatory markers after moderate consumption of red wine.

In the field of winemaking, malolactic fermentation is a key aspect in obtaining high quality wines. Unfortunately, in some oenological contexts effective evolution does not take place because of the occurrence of certain limiting factors for malolactic bacteria in wine. Simultaneous alcoholic and malolactic fermentation in grape must is a promising alternative that promotes the survival of bacteria, due to the absence of certain limiting factors such as ethanol or other toxic substances produced by yeasts in the native grape must. The risk of wine depreciation due to the spoilage activity of malolactic bacteria can be reduced by using selected strains of Oenococcus oeni, with proven behaviour in terms of malolactic fermentation occurring in the presence of sugars. In this work we compared the activity of a strain of Oenococcus oeni in malolactic fermentation of a Chardonnay grape must, using different winemaking protocols characterised by sequential or simultaneous inoculums of microbial starters. The results are discussed both in terms of fermentative behaviour and the quality of the wines obtained, with careful analysis of the main chemical parameters of the wines and of 47 different volatile compounds, giving an exhaustive overview of the opportunities and the risks related to different wine fermentation strategies.
Treatment with different fining agents of white musts from spoiled wine grapes
Authors: Meistermann Eric , Pinsun Michel
Published: May 2023

Fining agents have evolved significantly over the last twenty years. The need for winemakers to have objective references about the new products has prompted this study. The experiment consists in comparing the new fining products (charcoal, pea proteins, derivatives of chitin and composite products generally mixing PVPP + various proteins + bentonite) with reference products such as casein and PVPP and with non-treated controls. Fining agents were applied during clarification of 15 different musts obtained from wine grapes affected by different degrees and types of rot: fresh and dry Botrytis cinerea rot, powdery mildew and Botrytis contaminated with other fungi (Aspergillus, Penicillium, Basidiomycetes), giving the bunches offflavours that were earthy and resembled fresh mushrooms. This study highlights the importance of good clarification of musts. The quality of control wines, without any treatment, increases with the clarity of the must. In most experiments, clarification of the must around 50 Nephelometric Turbidity Units (NTU) can eliminate or reduce any organoleptic defects in wine without fining. Use of pectolytic enzymes may be necessary in order to reach this level of clarity. The new allergen-free fining agents have the same effectiveness as reference products such as casein and polyvinylpolypyrolidone (PVPP). Composite products are more efficient than pea protein alone and less than products including charcoal. However, the improvement of aromatic quality goes hand in hand with loss of body and persistence.

BACKGROUND:

The prevalence of diabetes mellitus has almost reached global epidemic proportions. Fortunately, the progress of the disease can be stemmed at the prediabetic level. The objective of the present study was to determine the frequency of impaired glucose tolerance (IGT) and its predictors in females of reproductive age in the urban slums of Lahore.

MATERIALS AND METHODS:

A cross-sectional study was conducted among females of reproductive age in the slums of metropolitan Lahore. The calculated sample size was 384. Data were collected using a structured questionnaire covering demographic variables, lifestyle, medical, and dietary history. The oral GT test was carried out on the study participants after a 10 hour overnight fasting. Data were entered and analyzed using Statistical Package for the Social Sciences (SPSS version 23). Frequency distributions and percentages were calculated for categorical variables, and the mean and standard deviation were calculated for continuous variables. The Chi-square test or Fisher’s exact test, as appropriate, was used to determine the association between IGT and various categorical variables. Logistic regression analysis was performed to determine the correlates of IGT after adjusting for confounders.

RESULTS:

The final sample size was 394 women; 17% of whom had IGT, and 8.6% had newly diagnosed diabetics. Results of logistic regression showed increased waist/hip ratio, lower literacy of father or husband, age, and low intake of pulses as significant predictors of IGT (P < 0.05).

CONCLUSION:

The frequency of IGT is high in females of reproductive age living in the urban slums of Lahore. There is a need for targeted health promotion and educational activities to improve the health and social conditions of slum dwellers.
Distant learning and primary school teacher burnout: Assessing the effect during coronavirus disease (COVID-19) in Jeddah, Saudi Arabia, 2021
Authors: Altwaim Najlaa M. , Kadi Mai S. , Alfakeh Solhi A.
Published: May 2023

BACKGROUND:

Teaching is indeed a very stressful occupation. Owing to the novel coronavirus SARS-CoV-2, certain changes were made in education in Saudi Arabia. A switch to a 100% distant learning in some courses was implemented, thereby increasing the burden on teachers. The aim of this study was to assess the level of burnout and the impact of distant learning on burnout in primary school teachers during the pandemic.

MATERIALS AND METHODS:

This cross-sectional study recruited 295 primary school teachers in Jeddah City, Saudi Arabia. Data were collected using self-administered questionnaire having two parts: the first part included questions on sociodemographic charecteristics and the second part included questions related to distant learning and the Arabic version of the Maslach Burnout Inventory. Chi-square test was used to assess association between burnout and various factors. For comparison of mean scores by various factors, analysis of variance (ANOVA) was performed.

RESULTS:

A high level of burnout was perceived by 48.4% of the teachers in the dimension of emotional exhaustion, 26.4% in the depersonalization dimension, and 60% in the reduced personal accomplishment dimension. Teachers in the public school showed a higher burnout score than teachers in the private schools. The teachers in 40–50 age group had higher scores than the teachers with other age groups. There were no significant differences in terms of gender and years of experience. A higher proportion of teachers working in private schools had higher personal accomplishment than teachers working in Government schools (P = 0.01). Regarding personal accomplishment and depersonalization subscales, there were differences between the different types of schools. The teachers who believed “distance/E-learning was difficult” had lower personal accomplishment score.

CONCLUSION:

According to the study, primary teachers in Jeddah suffer from burnout. More programs should be implemented to deal with teacher burnout and more research focusing on these groups should be done.
Risk factors for carpal tunnel syndrome in patients attending the primary care center of a tertiary hospital in Riyadh, Saudi Arabia: A case–control study
Authors: Alendijani Yaser A. , Abaalkhail Bahaa A. , Binsaeedu Abdullah S. , Alandijani Asim A.
Published: May 2023

BACKGROUND:

Carpal tunnel syndrome (CTS), the most common entrapment neuropathy in the upper extremity, is known to be a multi-factorial disease that raises medical and nonmedical risk factors. The aim of the current study was to determine the risk factors of CTS in patients attending the primary care center at a tertiary hospital.

MATERIALS AND METHODS:

A case–control study was conducted by reviewing all medical records of patients above the age of 18 years old diagnosed with CTS from 2015 to 2021. The selected cases were evaluated by physical examination and confirmed by a nerve conduction study. Cases and controls were matched by age, gender, and nationality, with a case-to-control ratio of 1:2. Odds ratios were calculated for association between carpel tunnel syndrome and various factors and Chi-sqauare test determined statistical significance. Multiple logistic regression was performed to adjust for confounding.

RESULTS:

The study recruited 144 cases with a mean age of 53.38 ± 12.20 years and 288 controls with a mean age of 53.80 ± 12.27 years. The majority of subjects were female (84.7%) and of Saudi nationality (68.3%). There was a significant difference in body mass index, employment status, number of years of employment, occupation, mean systolic blood pressure, mean low-density lipoprotein cholesterol level, and mean blood urea level between cases and controls (P < 0.05). Laboratory tests that were found to be significantly associated with CTS in univariate analysis were thyroid-stimulating hormone (crude odds ratio [COR] = 0.828) and urea level (COR = 0.802). In fully adjusted analyses, obesity (adjusted odds ratio [AOR] =3.080), chronic kidney disease (AOR = 3.629), and the use of corticosteroid (AOR = 0.470) were also significantly associated with CTS.

CONCLUSION:

Similar to the findings of other studies, this study identified several potential risk factors for CTS. More large-scale longitudinal studies are required to establish a precise causal association.

Published: May 2023

Background:

Insomnia in shift work has been associated with impairment in health and social life and poor quality of life among shift workers.

Aims and Objective:

The study aimed to assess insomnia, chronotype, and quality of life in nursing shift duty workers and to find an association among insomnia, chronotype, and quality of life in nursing shift duty workers of a tertiary care center in Saurashtra.

Materials and Methods:

A cross-sectional study was carried out among 300 nursing shift duty workers. Consented participants with at least one-night duty per week were included in our study. A semistructured proforma containing basic demographic details and scales such as ‘Insomnia Severity Index’ (ISI), ‘Composite Scale of Morningness,’ and ‘world health organization quality of life’ were distributed among all participants. Associations were examined by using t test and Chi-square test.

Results:

The prevalence of insomnia was 42.66% in this study. A total of 27.33% of participants were having mild insomnia, whereas 15.33% were having moderate-to-severe insomnia. Insomnia severity was statistically significantly associated with needle stick injury (p = 0.003) and years of shift work (0.031). Insomnia severity had been significantly associated with the chronotype of participants, negative but statistically significant correlation was found between the ISI score and mean score of all four domains of world health organization quality of life.

Conclusion:

Insomnia in shift work has been associated with evening chronotype and poorer quality of life of shift workers. Therefore, the management of insomnia is important for a better quality of life for shift workers. Participants with insomnia are more prone to needle stick injury during work.
