Effect of Paraquat Herbicide on Oxidative Stress Biomaker Enzyme Activities in C. Gariepinus
Authors: Nafi’u S. A , Suleiman K. , Ahmad M. K , Zakariyya M
Published: January 2022

Toxicity assessment was conducted for 96hr exposure duration using synthetic herbicide (paraquat dichloride 276g/L) on Claris gariepinus with mean weight range of 27.2 - 29.7g and mean length 10.95 -15.5cm. They were exposed to varying herbicide concentrations of 0.0, 3.45, 6.90, 10.35 and 13.5mg/L with 5-levels exposure concentrations in a Completely Randomized Design (CRD). Liver, gills and kidney tissues were analyzed for oxidative stress enzymes activities using Solarbio science assay kit (BC1170, 0170 and 0020). Four days lethal concentration (LC50) value for 96hr was found to be 7.298mg/L. The treated fish displayed erratic swimming with irregular opercular movement, loss of reflex, mucus secretion and increased air gulping with the increasing concentration of the herbicide compared with the control fish. Antioxidant biomarkers activities revealed that Glutathione S-transferase (GST), catalase (CAT) and superoxide dismutase (SOD) activities increased significantly (P<0.05) in the gills, liver and kidney tissues at higher concentrations compared with control. It can be deduced that alterations in the oxidative stress enzyme activities in the exposed fish to paraquat exert toxic effect on the liver, gills and kidney tissues. It is therefore recommended that appropriate authorities should develop strategies on minimizing the indiscriminate use of synthetic herbicides due to their impact on aquatic biota such as fish in order to reduce its potential risk to other non-target organisms.

Prévention du brunissement enzymatique de l’aubergine violette (Solanum melongena L.) par traitement thermique : analyses cinétiques et thermodynamiques
Authors: Yapi Jocelyn Constant , Ya Kouamé Claude , Gnanwa Mankambou Jacques , Kouame Lucien Patrice
Published: January 2022

Le brunissement enzymatique est associé à l'action des polyphénol oxydases (PPO) et des peroxydases (POD). Les produits de ces enzymes provoquent des changements indésirables de couleur et de saveur des aubergines transformées. Une dopamine oxydase responsable du brunissement enzymatique a été isolée de l’aubergine violette (Solanum melongena L.). Ainsi, l’inactivation thermique et l’analyse thermodynamique ont été étudiées sur une base cinétique afin de contrôler ce phénomène physiologique. Les études cinétiques ont montré que l’inactivation thermique de l’activité dopamine oxydase de l’aubergine violette suivait une cinétique de premier ordre aux températures comprises entre 35 – 80 °C, avec des constantes de vitesse (k) comprise entre 0,0101 ± 0,0001 et 0,0865 ± 0,0004 min-1. Les temps de réduction décimale (D) et k ont diminué et augmenté respectivement avec l’augmentation de la température, indiquant une inactivation plus rapide de la dopamine oxydase à des températures plus élevées. Les résultats suggèrent que dopamine oxydase est une enzyme relativement thermostable avec une constante de résistance (Z) de 50.25 ± 0,7 °C et une énergie d'activation (Ea) de 40.65 ± 0,6 kJmol-1. Les résultats thermodynamiques ont indiqué que les réactions d'oxydation étaient : non spontanées (ΔG > 0), légèrement endothermiques (ΔH > 0) et réversibles (ΔS < 0). Ces données cinétiques peuvent être utilisées dans la prévention du brunissement enzymatique de la pulpe d’aubergine violette par l'inactivation thermique de l'enzyme.

Enzymatic browning is associated with the action of polyphenol oxidases (PPO) and peroxidases (POD). The products of these enzymes cause undesirable changes of color and flavor of processed eggplant products. A dopamine oxidase responsible for enzymatic browning was isolated from violet eggplant (Solanum melongena L.). Thus, thermal inactivation and thermodynamic analysis were studied on a kinetic basis to control this physiological phenomenon. Kinetic studies showed that thermal inactivation of dopamine oxidase activity in purple eggplant followed first-order kinetics at temperatures between 35 - 80 °C, with speed constants (k) values between 0.0101 ± 0.0001 and 0.0865± 0.0004 min-1. The decimal reduction times (D) and k values decreased and increased, respectively, with increasing temperature, indicating more rapid inactivation of dopamine oxidase at higher temperatures. The results suggest that dopamine oxidase is a relatively thermostable enzyme with a resistance constant (Z) value of 50.25 ± 0.7 °C and an activation energy (Ea) of 40.65 ± 0.6 kJmol-1. Thermodynamic results indicated that the oxidation reactions were: non-spontaneous (ΔG > 0), slightly endothermic (ΔH > 0), and reversible (ΔS < 0). These kinetic data can be used in the prevention of enzymatic browning of purple eggplant pulp by thermal inactivation of the enzyme.

Published: January 2022

Cette synthèse bibliographique vise à comprendre l’état des connaissances des pratiques de chasse et leurs effets sur les espèces de faune dans les périphéries des Aires Protégées d’Afrique de l’Ouest. Elle identifie également les lacunes dans les critères de classification des types de chasse et la prise en compte des aspects théoriques dans les diverses analyses. Trois types de chasse dont la chasse de subsistance (27,5% des documents), la chasse commerciale (63,75%) et la chasse sportive (8,75%) ont été identifiés. Si la chasse de subsistance prélève les oiseaux et les rongeurs en majorité, la chasse commerciale capture toutes les espèces rencontrées tandis que la chasse sportive abat les espèces avec les trophées comme les éléphants et les lions. L’impact négatif de la chasse est dénoncé par les auteurs lus. Bien que la prise en compte des aspects spatiaux et environnementaux et les caractéristiques biologiques des espèces prélevées soient importante dans la gestion de la faune, les documents analysés ont occulté ces aspects. Le présent travail suggère des études complètes sur la chasse traditionnelle en y intégrant les aspects spatiaux et environnementaux.

This bibliographic review aims to understand the state of knowledge of hunting practices and their effects on species of fauna in the outskirts of West African Protected Areas. It also identifies the gaps in the criteria for classifying the types of hunting and the taking into account of theoretical aspects in the various analyzes. Three types of hunting including subsistence hunting (27.5% of documents), commercial hunting (63.75%) and sport hunting (8.75%) were identified. While subsistence hunting takes the majority of birds and rodents, commercial hunting captures all the species encountered while sport hunting cuts down species with trophies such as elephants and lions. The negative impact of hunting is denounced by the authors read. Although the consideration of spatial and environmental aspects and the biological characteristics of the species collected are important in wildlife management, the documents analyzed have overlooked these aspects. The present work suggests comprehensive studies on traditional hunting by integrating spatial and environmental aspects.

Authors: Agwa O.K. , Chukwunweike C.A. , Ire F.S.
Published: January 2022

The use of plant waste product for maximum sustainability has led to the search for bio based raw material such as Chlorella vulgaris which can make a tremendous contribution on the ecological and economical production of different organic acids like lactic acid. This study aimed to evaluate the enzymatic and or acidic hydrolysis of Chlorella vulgaris cell wall Intercellular starch as a source of fermentable sugar for lactic acid production. Lactic acid was produced through acid hydrolysis, enzyme hydrolysis and a combination of acid and enzyme hydrolysis of four different substrates. Each of the substrate was inoculated with a lactic acid bacterium (Lactobacillus plantarum) and a fungus (Rhizopus oryzae) while acid/enzyme hydrolysis was inoculated with mixed culture of the organism within a retention period of tendays.  Results showed that the physico-chemical properties of C. vulgaris had a total carbohydrate of 17.4% and a reducing sugar of 24.0µg/ml. According to treatment, C. vulgaris had the highest reducing sugars (6.4 ± 0.2) and (4.4 ± 0.3) with Lactobacillus Enzyme Hydrolysis (LEH) and Rhizopus Enzyme Hydrolysis (REH) treatments, respectively indicating that C. vulgaris was the most hydrolyzed sample. Results of the optimization of various responses showed that using Corn Steep Liquor (CSL), REH day 2 treatment for fermentation at 370C for 48h were best combinations that yielded the optimal of Y1=0.249, Y2= 5.461 and Y3=33.704, respectively with a desirability of 0.619. The results indicated Chlorella vulgaris produced the highest lactic acid of about 20% signifying that its biomass contains high source of carbohydrate accessible for lactic acid production.

Authors: Idibie C.A. , Omo-Udoyo E. , Fielami J.
Published: January 2022

Batch kinetic process was employed in the evaluation of the dehydration of ethyl alcohol-water mixture via locally synthesized activated starch from cassava and maize. The equilibrium data generated were analyzed using adsorption isotherm and kinetic mechanism model equations. Results showed that the optimum concentration of 74.07% was obtained when 4g of modified cassava starch was contacted with 70ml of ethyl alcohol of initial concentration 69.72% at a contact time of 20min where the volume of ethyl alcohol recovered was 65ml. The maize starch could only achieve 72% optimum concentration when same 4g of modified maize starch was used with 70ml of ethyl alcohol with an initial concentration of 68.15%, at a contact time of 20 min where 60 ml of ethyl alcohol was recovered. The adsorption isotherm was studied using two well-known models; Langmuir and Freundlich. Although results showed that the adsorption process obeyed both models, however, the Freundlich model gave a better fit with an R2 value of 0.984 as against 0.974. The kinetic study on the other hand showed that the adsorption process obeyed the pseudo-second order.

Published: January 2022

The effect of shade on the germination, growth, and development of Abelmoschus esculentus (L.) Moench (Okra) was investigated. This experiment was carried out using two varieties of A. esculentus seeds (Kirikoa F1 and Hire varieties) which were replicated 5 times for both under shade and under direct sunlight as growth conditions. The seeds and soil were tested for liability and physicochemical composition, respectively, before the commencement of the work. The parameters assessed following standard procedures on A. esculentus plant were number of leaves, plant height, leaf petiole length, internode, pigments and nutritional composition. The seeds germinated within 3 – 4 days after planting. Among the treatments at ninth week after planting, Kirikoa F1 variety under shade had the highest number of leaves (7.0±1.00), plant height (27.80±5.718 cm), petiole length (7.60±2.408 cm), leaf length (11.30±2.168 cm) and leaf width (10.20±1.924 cm). Also, internode (3.40±1.517 cm) was high at Kirikoa F1 under direct light. Total chlorophyll content of the varieties under light and under shade were: 1.441 mg/g and 1.254 mg/g, respectively for Kirikoa F1 and 0.549 mg/g and 0.938 mg/g, respectively for Hire. Okra under shade had high moisture content (87.36%) when compared to okra under direct sunlight (83.24%) while the reverse was the case for other nutritional composition (carbohydrate, ash content, crude lipid, crude protein and crude fibre). The study showed that Kirikoa F1 variety performed better than the Hire variety during development, and most indices of growth had higher performance under shade condition than under direct light for the okra varieties, respectively.

Assessment of radius of influence of sparging well and biosparging operations in Ozzmukpbu, Zizkwere LGA, Rivers State, Nigeria
Authors: Tijani S.O. , Obafemi A.A. , Babalola A.E. , Usman A.O.
Published: January 2022

The capacity to analyse the influence of the operation on the targeted wells is critical to the efficacy of biosparging. Its success varies based on the profile of the targeted region in which the operation is carried out. The Omkpbu investigation was able to establish the impact of the activities as defined by the soil texture, which is clay silt in nature. To establish the ROI inside the research region, a 10m deep sparging well (SW) and 8m deep monitoring wells (MW) were constructed at 1m, 2m, 3m and 5m intervals around the sparging well. The influence of the sparging well became obvious on the 13th, 14th and 15th day of the sparging operations. This resulted in an increase in the dissolve oxygen in the ground water condition across the monitoring wells. In comparism with the baseline data there were massive improvement in the presence of dissolve oxygen in the ground water at an increasing rate as the operations continues. Monitoring well 1, 2, 3 and 4 on the 13th day felt an increased rate of influence at 2.6mg/l, 2.5mg/l, 4.31mg/l and 2.83mg/l as against the base line data of 1.9mg/l, 1.5mg/l, 1.7mg/l and 1.9mg/l respectively. Similarly, there were also an increased influence from data generated on the 13th day as at the 14th day the presence of the dissolve stood at 2.7mg/l, 3.6mg/l, 4.9mg/l, and 3.0mg/l respectively. The 15th day noticed a massive increase in the dissolve oxygen in groundwater as it stood at 4.4mg/l, 6.2mg/l, 6.17mg/l, and 4.78mg/l respectively. Biosparging has a great influence in increasing dissolve oxygen in groundwater which essentially is a major requirement for addressing groundwater contamination.

Published: January 2022

This article reviews the available evidence on the effectiveness of gloves in preventing infection during care provided to patients under contact precautions, and analyses the risks and benefits of their systematic use. Although hand hygiene with alcohol-based handrub was shown to be effective in preventing nosocomial infections, many publications put the effectiveness and usefulness of gloves into perspective. Instead, literature and various unpublished experiences point towards reduced hand hygiene compliance and increased risk of spreading pathogens with routine glove use. Therefore, hospitals should emphasise hand hygiene in their healthcare staff and, instead of the routine use of gloves when caring for patients under contact precautions, limit their use to the indications of standard precautions, i.e., mainly for contact with body fluids. Wide and easy access to alcohol-based handrub and continual teaching are essential. If such conditions are met and adherence to hand hygiene is excellent and regularly assessed, the routine use of gloves for patients under contact precautions seems no longer indicated.

Spaceships and Underwater Tribes – Afrofuturistic Contexts of the Flying Africans Myth This article’s objective is to compare different afrofuturistic texts containing references to the Flying Africans myth. I am going to analyse Anthony Joseph’s text The African Origins of UFOs and Nalo Hopkinson’s novel The Salt Roads in the musical funk and ambient context. My main focus is the song Star Child from album The Mothership Connection by the American band Parliament-Funkadelic and an electro-ambient album by the American group Drexciya, entitled The Quest, built around a story about an underwater human race living in the bottom of the Atlantic, born of pregnant women thrown overboard by slave ships.
Syndrom ciągłości i nieciągłości
Authors:   Maria Curie-Sklodowska University in Lublin, Poland, Pękala Teresa
Published: January 2022

The Syndrome of Continuity and Discontinuity The article discusses the problem of understanding changes in modern art as “the syndrome of continuity and discontinuity”. The term was used by Stefan Morawski in describing relationships between the avant-garde and neo-avant-garde. The author poses the thesis that this model of thinking is characteristic of the history of art in the modern period and analyzes its sources and consequences using the example of Morawski’s concept. The first part of the study discusses selected themes in Morawski’s scholarly achievement that characterize it as the thought entangled in the pitfalls of the discourse of modernity whose weaknesses the esthetician notices or sometimes even stigmatizes but which he does not want or is unable to give up. Both the avant-garde formations and postmodernism were treated as symptoms of the crisis of Western culture, which is why taking a stance on the violation of the existing boundaries of art and on understanding its function was a form of declaration of a world-view attitude. Another part of the article focuses on analytical categories such as ‘boundary’, ‘identity thinking’, ‘space between’, or ‘otherness.’ The reflections are conducted in the context of contemporary theories that point out the weakening of metaphysical thinking.
Stany emocjonalno-społeczne wśród młodzieży akademickiej w okresie pandemii COVID-19 (raport z badań)
Authors: Owczarz Magdalena
Published: January 2022

Przeprowadzone w 2020 roku badania wykazały, że okres pandemii wpłyną na ogół negatywnie na środowisko studenckie. Pojawiły się negatywne stany emocjonalne, które osłabiły psychikę badanych a w niektórych przypadkach doszło nawet do załamania nerwowego i myśli samobójczych. Studiujący utracili poczucie własnej wartości, niektórych dotknęło poczucie krzywdy i cierpienia psychicznego. Pojawiły się obawy o przyszłości i realne zagrożenie o utratę własnego zdrowia i bliskich osób. Ogólne zmęczenie psychiczne i fizyczne, wrażenie spowolnienia upływającego czasu i ograniczenia w kontaktach międzyludzkich wymusiły zmiany w codziennym rytmie dnia a nawet korekty w planach życiowych. Sytuacja pandemiczna wpłynęła także zasadniczo na osłabienie tempa i motywacji do nauki i pojawienia się takich stanów jak utrata zainteresowań, obniżenie poziomu koncentracji, trudności z zapamiętywaniem. Niepokojące może się wydać, że już w drugiej fali pandemii wśród młodzieży studiującej był aż 29% koronasceptyków. Za pozytywne zjawiska można uznać to, że okres izolacji przyczynił się do zwrócenia uwagi na jakość i ilość kontaktów międzyludzkich i właściwe ich docenianie oraz fakt, że skrajnie uciążliwa sytuacja nie spowodowała ucieczki do używek i środków farmakologicznych w celu poprawy samopoczucia.

The emotional and social state among academic youth during the COVID- 19 pandemic (Research report)

The research was conducted in 2020 and showed that the period of the pandemic will generally have a negative impact on the student’s community. Among students negative emotional states appeared that weakened the psyche of the respondents, and in some cases there was even a nervous breakdown and suicidal thoughts. The students lost their self-esteem, some were touched by a sense of psychological harm and suffering. Among students there were fears about the future and a real threat to the loss of one’s own health and that of relatives. Mental and physical fatigue of students, the impression of slowing down the passage of time and limitations in interpersonal contacts forced changes in the daily rhythm of the day and even corrections in their life plans. The pandemic situation also significantly reduced the pace and motivation to learn and the emergence of such conditions as loss of interests, decreased concentration, difficulty remembering. It may seem disturbing that already in the second wave of the pandemic, as many as 29% of coronersceptics were among the students who studied there. The positive phenomena were that the period of isolation contributed to drawing attention to the quality and quantity of interpersonal contacts and their proper appreciation, and the fact that the extremely burdensome situation did not result in resorting to stimulants and drugs in order to improve well-being.

A Case of Acute Pancreatitis Following Computed-Tomography Scan
Authors: SAYINALP Başak , ÖZIŞIK Lale , PARLAK Erkan
Published: January 2022

Introduction:

Acute pancreatitis is a common cause of hospitalization among gastrointestinal disorders and its frequency has been rising in the past few years. The majority of cases are due to alcohol use, gallstones and hypertriglyceridemia. However, there still remain a significant number of cases in which no causative factor can be found and therefore called idiopathic. Contrast-induced pancreatitis is a rare cause pancreatitis and there are only a few cases reported so far. Here we present a case of mild acute pancreatitis following iodinated contrast exposure.

Case Presentation:

A 42-year-old female patient with a history of lymphoma was admitted to our clinic with severe abdominal pain and nausea. Her blood tests revealed elevated pancreatic enzyme levels and mildly elevated liver function tests. Upper abdomen magnetic resonance imaging revealed pancreatic inflammation without any sign of necrosis. Since her complaints began after a computed-tomography scan that she had earlier that day for the evaluation of lymphoma and no other cause could be found, iodinated contrast was thought to be the cause of acute pancreatitis in this patient.

Conclusion:

Contrast agents seem to be a rare cause of acute pancreatitis, however taking the increasing availability of procedures involving radiocontrast agents into consideration, it is important to keep in mind that clinicians may come across more cases of contrast-induced acute pancreatitis in the future.
Taking Nativism to the Streets
Authors: Botsch Gideon
Published: January 2022

In this article, I give an overview on nativist street protests in Germany from the early nineteenth century to the present from an historical perspective. In a preliminary remark, I will reflect on some recent developments in Germany, where nativist protest campaigns against immigration took place in the streets when voters were turning towards the populist radical right party Alternative für Deutschland (AfD). In the first section, I will outline an older tradition of anti-immigration protest in nineteenth and early twentieth century Germany, which is closely connected to modern antisemitism. In sections two and three, I will retrace how, from the late 1960s onward, the far right in the Federal Republic of Germany (FRG) discovered concerns about immigration in the German population, addressed them in protest campaigns and developed narratives to integrate such sentiments into a broader right-wing extremist ideology, itself deeply rooted in antisemitism. Studying nativism and the radical right from an actor-oriented perspective, I will focus on traditionalist movements, including the Nationaldemokratische Partei Deutschlands (NPD) and neo-Nazi groups.
Non-Citizens Protests in Germany since the 1980s
Authors: Alexopoulou Maria
Published: January 2022

This article focuses on three specific episodes of non-citizen protests in the Federal Republic of Germany. The common characteristic of these protests, fought out by different groups in different contexts and at different times, was a “claim to the political,” which were made visible through a demonstration of a precarious civil rights status. Embedded in a long history of racial knowledge about the German and its Other, these migrant protests indicate how essential “performative forms of power” are for individuals and groups without the specific political rights that remain the prerogative of nation-bound citizens. Special attention is paid to transgressions that delegitimized these non-citizen protests even in the eyes of some of their supporters and to actions that are considered illegal by established law, and are thus classified as unwelcome. Instead of providing a closed narrative or recounting the history of migrant protests, the goal here is to add more pieces to the unwritten history of the (ongoing) migrant civil rights movement in Germany.
“Protest? Bollocks!” On Public Perceptions of Punk in West Germany
Authors: Robel Yvonne
Published: January 2022

The article thematizes the phenomenon of punk as an example of “unconventional” and “unwelcomed” protest. It focuses on the public perception of West German punks from the late 1970s into the 1980s. In this early phase, punks caused confusion especially because of their alleged passivity. Their seeming rejection of a concept of being (politically) active was regarded as provocative, as the idea of “activity” largely dominated notions of legitimate political protest at that time. Punk was considered destructive and contentless, but non-political and as such “non-real” as a form of protest. Moreover, “experts” from the social sciences and pedagogy, politicians, and journalists interpreted the behaviour of the youth in social terms and responded to the “problem” with attempts to “understanding” and “help.” From their point of view too, Punks seemed to be unable to detect any political issues of their own or to fulfil notions of meaningful forms of protest. Using the example of punk perceptions, the article examines how collective knowledge about legitimate and proper forms of protest is negotiated through demarcations.

Con el surgimiento de la pandemia alumnos de todo el mundo dejaron de asistir físicamente a la escuela cambiando la modalidad de enseñanza presencial a una modalidad a distancia creando un caos por lo repentino del suceso. La Coalición Mundial para la Educación Covid-19 estimó que un gran porcentaje de alumnos y maestros no estaban preparados para la enseñanza-aprendizaje a distancia ya que carecían de habilidades digitales y de los dispositivos necesarios para su correcta implementación dada la premura derivada de la contingencia. Así mismo un porcentaje de estudiantes no tendrían los recursos suficientes para afrontar la nueva realidad.

En respuesta a esto, cada país adoptó diferentes políticas para reabrir escuelas con restricciones estrictas y los maestros y alumnos han seguido con sus procesos de adaptación a lo digital creando espacios de enseñanza-aprendizaje con aciertos y errores en el uso de herramientas y aplicaciones. Ante este escenario parece que la tecnología digital en la educación llegó para quedarse, aún en el caso de educación presencial, por lo cual es interesante  entender cómo la pandemia modificó diferentes hábitos de estudiantes de las carreras de nivel superior con el fin de adecuarlos y adaptarlos a la educación presencial, por lo cual, esta investigación se enfoca a determinar bajo un esquema de educación virtual el tiempo dedicado a siete aspectos cotidianos  que impactan en el rendimiento académico como lo son el estudio, trabajo, ejercicio, alimentación, sueño, convivencia familiar y hobbies; describiendo la tendencia de las respuestas con el tiempo dedicado a cada uno de los aspectos mencionados de tal manera que los resultados obtenidos sirvan como base para estudios post-pandemia.
Diagnóstico de Seguridad Alimentaria en algunas de las comunidades indígenas del Municipio de Huatabampo.
Authors: Zazueta Arguilez Celia
Published: January 2022

El presente estudio tuvo como objetivo identificar si existe seguridad alimentaria en comunidades indígenas del Municipio de Huatabampo, esto es, el acceso permanente de todas las personas a los alimentos como son las verduras, frutas, granos integrales y grasas saludables, que se requieren para una vida activa y saludable (Latham, Organización de las Naciones Unidas para la Alimentación y la Agricultura., 2002). Este estudio se realizó a petición de un grupo de personas interesadas en apoyar a los grupos mas vulnerables y establecer un camino enfocado para que los jovenes continuen con esto, en favor de la comunidad, denominado INICIATIVA CIUDADANA HUATABAMPO.  Para esto se determinó elegir diez comunidades de manera aleatoria y de fácil acceso, siendo requisito presenten un alto grado de marginación, siendo estas un total de 70 de 210 comunidades existentes (SEDESOL, 2015), además de medir si en la pandemia generada por el COVID 19 este grado de marginación había aumentado o disminuido. Por ser un número grande de comunidades se tomaron solamente diez comunidades (ver tabla 1), elegidas como muestras para esta investigación debido al tiempo limitado en el cual se esta llevando a cabo, de septiembre a noviembre del presente año, siendo el estudio de tipo cualitativo transversal  ya que solo se tomarán en cuanta la información que se recabe en estas fechas.

 Se determinó solo encuestar  a las mujeres como jefes de familia ya que estas son las que tradicionalmente compran y preparan el alimento, teniendo en cuenta las responsables de levantar la información que antes de preguntar informaran el significado de seguridad alimentaria. Se determinó aplicar la escala de seguridad alimentaria que ya ha sido validada anteriormente para los hogares de Venezuela y Colombia, presentando este instrumento en anexos.  (Álvarez, Estrada, Montoya, & Melgar-Quiñónez, 2006)
Confirmatory model of environmental expectations in the COVID-19 era
Authors: García Lirios Cruz , Rubén Sandoval Francisco , Juárez Nájera Margarita
Published: January 2022

Studies of risk perception, in relation to the governance of risk events, have advanced towards a management, production and knowledge transfer system focused on the impact of the media on audiences and eventually on the leaders of Civil protection institutions, but the absence of research encouraged the present work to establish the reliability and validity of an instrument. The proposal was based on a non-experimental study and a non-probabilistic sample selection of 100 students from a public university. Based on a structural model, it was found that Internet users perceive risks and affect media perception and perception social on the perception of risk events, although there are lines of research concerning the mediation of such dependency relationships.
Apuntes para una refundamentación de la democracia
Authors: Compte Nunes Guillem
Published: January 2022

Desde un enfoque normativo e interdisciplinario se realiza una crítica a la democracia liberal-representativa a partir del modelo principal-agente, lo cual supone identificar un conflicto de interés político que vicia el gobierno representativo. Se muestra, a continuación, cómo ese conflicto, en distintas versiones, aparece en teorías de la ciencia política, la administración pública y el derecho, y que su resolución reiteradamente implica cierta separación de poderes. Con base en este análisis, se propone un nuevo fundamento para la democracia, consistente en la propiedad popular directa del sistema político, que puede institucionalizarse en un Poder Ciudadano.

Bu nedenle hat belirleme, graf yani ağ yapısındaki sistemlerin tasarlanmasında kullanılabilen bir Minimum Yayılan Ağaç (MYA) problemi olarak ele alınmıştır. Problemin çözümünde Prim, Kruskal algoritmaları ve matris yöntemi kullanılmıştır. Her üç yöntem ile optimal sonuç elde edilmiştir. Minimum MYA mesafesi 29,09 km’dir. Ancak söz konusu yöntemler için süreçler; işlem kolaylığı, iterasyon sayısı, karmaşıklıkların minimuma indirilmesi açısından değerlendirildiğinde, daha avantajlı olan matris yönteminin gerçek hayat MYA problemlerinde kullanılmasının daha uygun olacağı sonucuna varılmıştır.

Objective: To investigate the correlation of Adenine-1012-Guanine (rs4516035) promoter region polymorphism of vitamin-D receptor gene with serum levels of omentin-1, vitamin-D and vitamin-D receptor protein in patients with coronary artery disease.
Method: The case-control study was conducted January to June 2020 at the cardiac unit of Civil hospital Karachi (CHK), and comprised coronary artery disease patients and controls. The tetra-primer amplification refractory mutation system polymerase chain reaction method was used to genotype Adenine-1210Guanine polymorphism in the vitamin D receptor gene.  Serum levels of omentin-1, vitamin-D, and vitamin-D receptor protein were measured in both the groups using an enzyme-linked immunosorbent assay. Data was analysed using SPSS 17.
Results: Of the 1,000 subjects, there were 500(50%) cases; males 306(61.2%) and 194(38.8%) females with overall mean age of 51.08±9.55 years. The remaining 500(50%) were controls; 290(58%) males and 210(42%) females with overall mean age of 50.9±10.78 years. The mutant Guanine allele was more prevalent in controls 261(52.2%), and had a non-significant correlation with coronary artery disease (p=0.45).  Among the cases, the wild Adenine-Adenine genotype had a higher prevalence 402(80.4%) and had a significant correlation with coronary artery disease (p<0.001). The heterozygous genotype Adenine-Guanine was significantly more predominant among the controls 346(69.2%) compared to the cases 66(13.2) (p=0.002).
Conclusion: Adenine-1012-Guanine polymorphism in the vitamin-D receptor gene was found to be a protective polymorphism for coronary artery disease in the recessive model.
