Description du sujet. L’érosion hydrique est une problématique particulièrement importante, notamment dans la zone méditerranéenne et semi-aride. Cette zone est caractérisée par des régimes pluviométriques irréguliers qui ont une influence considérable sur les pertes en sol. Dans les zones montagneuses, les phénomènes d’érosion hydrique sont accentués par les fortes pentes et la couverture réduite du sol. Les barrages alimentés par ces zones subissent un envasement lié à une érosion importante. L’envasement de ces barrages limite drastiquement leur capacité et donc leur durée d’exploitation. Lorsqu’ils sont utilisés pour la recharge de nappes phréatiques, les lâchers entrainent la remise en suspension des particules fines qui s’accumulent au niveau des zones de recharge et réduisent la capacité d’infiltration par colmatage de la porosité du sol, ce qui conduit à un abattement important des niveaux piézométriques. De plus, les nappes phréatiques situées dans la zone côtière sont sujettes à des pompages intensifs. Ces deux phénomènes ont pour conséquence de rendre les nappes particulièrement sensibles aux intrusions marines. Objectifs. Cet article vise, d’une part, à quantifier le taux d’envasement dans le cas du barrage de Boukourdane (Nord de l’Algérie), qui est utilisé pour la recharge des nappes phréatiques et à montrer, d’autre part, la diminution de la perméabilité au niveau du champ captant avec la gestion actuelle des lâchers. Méthode. Les débits solides ont été mis relation avec les débits liquides et la concentration en sédiments prélevés ponctuellement dans l’oued. La relation établie a permis d’évaluer les apports solides dans le barrage de Boukourdane. L’impact des lâchers sur la recharge du champ captant a été évalué par regroupement des puits et forages du champ captant à l’aide de l’heuristique k-moyenne. Des régressions ont ensuite été appliquées sur les variations piézométriques de chacun des groupes. Résultats. Le taux d’érosion spécifique des sols, aussi appelé taux de dégradation spécifique des sols, a été évalué à 366 t·km-2·an-1 pour la période de 1993 à 2005. L’augmentation de la fréquence des pluies exceptionnelles se traduit par une augmentation du taux d’érosion des sols à 446 t·km-2·an-1 (+ 22 %) pour la période de 1993 à 2013. Ces valeurs correspondent à des volumes de vase accumulés au droit du barrage respectivement de 8·104 m³·an-1 et 11·104 m³·an-1. Conclusions. Une modification de la gestion des lâchers actuelle a un impact positif sur la restauration partielle de la conductivité hydraulique et de facto, sur la lutte contre les intrusions marines.

Description of the subject. Quercus rubra L. is considered an invasive species in several European countries. However, little is known about its dispersal in the introduced range. Objectives. We investigated the significance of animal dispersal of Q. rubra acorns on the ground by vertebrates in its introduced range, and identified the animal species involved. Method. During two consecutive autumns, the removal of acorns from Q. rubra and from a native oak was assessed weekly in forest sites in Belgium. We used automated detection camera traps to identify the animals that removed acorns. Results. Quercus rubra acorns were removed by wood mice (Apodemus sylvaticus L.), red squirrels (Sciurus vulgaris L.), rats (Rattus sp.), and wild boars (Sus scrofa L.). The two former are scatter-hoarding rodents and can be considered potential dispersers. Conclusions. Dispersal of Q. rubra acorns in Western Europe by scatter-hoarding animals may help the species increasingly colonize forest ecosystems.

Published: February 2022

Description of the subject. Edible mushrooms cultivation is one of the most important agro-industries in Mexico, showing good impact on food production through a controlled biotechnological process. National production is supported by foreign strains although this region has a great biological diversity in wild mushrooms species with adaptatively advantages to the local environment, but these genetic resources have been few studied, especially for Agaricus species. Objectives. To unravel the potential of wild Mexican strains of Agaricus bisporus for the production of fruiting bodies on compost. Method. The mycelial growth rate of eight A. bisporus strains (two wild, six commercial) in culture media was assessed by supplementing a malt extract medium with yeast extract (YMEA), yeast extract and indulin AT (YMEA-indulin AT), and compost extract (CMEA) at three different incubation temperatures (22, 25 and 28 °C). Mycelial growth was evaluated in solid media (mm·day-1) and liquid culture (decrease in the phenol content). Four strains (two wild, two commercial) with the best in vitro results were selected to obtain carpophores on compost and evaluate their yields. Results. The highest values of mycelial growth were observed in CMEA and the greatest decrease in phenol content was recorded for YME. Biological efficiencies of the four selected strains were 50.8 to 95.5%, and yields were 7.4 to 14.1 kg·m-2 in crop cycles of 74 to 98 days. Basidiomes 5 to 15 cm in diameter predominated. Conclusions. The characteristics of the wild strains indicate their suitability for the regional market, but additional experiments are necessary to improve their productivity parameters.
Corporate social responsibility in non-profit organizations
Authors: Plaisance Guillaume 
Published: February 2022

The concept of corporate social responsibility (CSR) in nonprofit organizations (NPOs) is a challenge for the literature and for the organizations themselves. The concept is often confused with social responsibility or sustainability. The pleonasm between CSR and the mission, values and nature of NPOs also raises questions. Finally, the relevance of the concept in its current state to NPOs calls into question, because of the “corporate” terminology.
Design/methodology/approach: Based on a literature review, this article proposes to respond to these different gaps thanks to an analysis of the definitions, the theories, measurement methods and content of research dedicated to CSR, social responsibility and sustainability.
Findings: The research underlines the triple relevance of the concept of CSR in NPOs. Its relevance to the other two concepts, its strategic importance and the interest of differentiation from for-profit organizations.
Originality: This article proposes a literature review on CSR in NPOs, a subject that is still emerging in the literature but which nevertheless needs to be addressed in the current context of multiple crises.

Гравитация оказывает сильное влияние на физиологию человека, включая атрофию мышц, снижение плотности костей, дисбаланс иммунной и сердечно-сосудистой систем, эндокринные нарушения. Эти физиологические изменения представляют собой серьёзные препятствия для длительных космических путешествий. Механизмы нарушения физиологии человека в условиях микрогравитации остаются неизвестными, что порождает многочисленные открытые вопросы, касающиеся адаптивных изменений, которые происходят на клеточном и молекулярном уровне. Использование наземных средств моделирования микрогравитации позволяет получить данные о влиянии невесомости на биологию разных клеток. В этом обзоре рассматриваются последние данные о влиянии моделированной микрогравитации на клеточном уровне: на адгезию, морфологию, механочувствительность и апоптоз. Таким образом, исследования, проводимые в условиях микрогравитации, могут расширить наши знания, о биологических механизмах, лежащих в основе клеточной физиологии и патофизиологии человека.
Gravity has a profound influence on human physiology, including muscle wasting, decreased bone density, immune and cardiovascular functions, and endocrine disruption. These physiological changes represent major obstacles to long-term space missions. The mechanisms by which human physiology is disrupted in microgravity remain unknown, rendering numerous open questions regarding the adaptive changes that occur at the cellular and molecular level in response to microgravity. The use of ground-based facilities to simulate microgravity provides a better understanding of the effect of weightlessness on cells. This review will give recent insights into the impact of simulated microgravity on cells and how this technology may improve our understanding of the effects of space on human physiology and pathophysiology.

Published: February 2022

Proyek Hydrant House adalah jenis proyek konstruksi yang membuat area tanki tandon air bawah tanah, beserta instalasi pompa utamanya. Proyek Hydrant House tersebut akan dikerjakan oleh tim internal perusahaan, yaitu Departemen Sipil PT XYZ. Terkait lama pengerjaan proyek Hydrant House, pihak manajemen memberi target selama kurang lebih 3 bulan. Namun, lama waktu tersebut dapat ditinjau ulang dengan catatan Departemen Sipil PT XYZ dapat melampirkan rincian perhitungan schedule dari proyek tersebut. Sejauh ini Departemen Sipil PT XYZ dalam merencanakan proyek hanya berdasarkan metode scheduling sederhana dan pengalaman saja. Perlu dilakukan perencanaan yang lebih sistematis dan terukur agar dapat mencegah terjadinya permasalahan di kemudian hari. Jadi, dalam melakukan penelitian terkait perencanaan proyek, penulis akan menggunakan metode PERT-Type System. Dari penelitian ini dapat diperoleh kesimpulan, yaitu : terdapat tiga level (proyek, tugas, sub-tugas) dari proyek Hydrant House dan dari tiga level tersebut terdiri dari 34 sub-tugas. Terkait lama proyek dapat terselesaikan adalah selama 120 hari, dengan probabilitas keberhasilan sebesar 12%. Oleh karena itu, penulis memberi opsi peluang keberhasilan terselesainya proyek sebesar 95% adalah selama 139.23 hari atau 140 hari. Jadi, agar dapat tercapai penyelesaian proyek, maka proyek paling tidak harus dikerjakan selama 140 hari. Karena probabilitas penyelesaian 140 hari lebih besar (95%), jika dibandingkan dengan probabilitas penyelesaian 120 hari (12%). Kemudian diketahui lintasan kritis pada proyek Hydrant House adalah yang dilalui oleh alur 1-6-7-8-9-10-11-12-13-14-15-16-17-18-19-20-22-23-24-25-26-27-29-30-31

The Relationship Between the Tasks Aimed at the Prevention of Extraordinary Incidents, the Preparation for the Mitigation of their Consequences and the System of Protection
Authors: Hornyacsek Júlia 
Published: February 2022

Extraordinary incidents, including disasters, usually cause significant damage to nature, the built environment and human lives. An approach, accepted by experts, is gaining more and more ground in the field of protection and research: it is not enough to respond to incidents following their occurrence, but great attention should be paid to prevent them, and authorities should be fully prepared to mitigate their consequences in due time. What does the preparation for extraordinary incidents mean, where is the place of these tasks in the system of protection, what are the tasks of the prevention phase, and how can the preparation activity be more efficient? In the article the author analyses the complex system of protection/defence, its subsystems, and then she demonstrates the place of disaster management and its subsystems in this environment. She examines the tasks of preventative protection against threat factors, with special regards to the tasks of the prevention/preparation phase. In the light of Hungarian and international prevention practice, she shows the up-to-date methods and tools with the help of several examples.

El propósito del presente estudio es analizar la situación actual de la parroquia Urbina para identificar estrategias que permitan la promoción de la economía, mediante el estudio de las variables desarrollo económico, bienestar - cohesión social, capital territorial y establecer las potencialidades económicas, productivas, sociales, culturales y naturales que la parroquia dispone en cada una de ellas. La investigación fue desarrollada bajo un diseño no experimental, de tipo transversal con un enfoque cuantitativo de alcance descriptivo, para recolectar la información se utilizó encuestas dirigidas a la población, una entrevista a un representante de la parroquia y a una asociación, el procesamiento de la información se lo realizó mediante SPSS y Excel, se presentó los resultados a través de figuras y tablas de contingencia. Con base en la investigación, se detectó que las principales actividades económicas de la parroquia son la agricultura y la ganadería, teniendo como principales productos la leche y la papa, pese a que se tiene gran producción y de calidad, estos sectores están estancados a causa de los limitados recursos disponibles y al desconocimiento en temas de industrialización y emprendimiento. Además, se determinó que Urbina cuenta con un importante potencial de recursos tangibles e intangibles, sin embargo, algunos de ellos tienden a desaparecer por la falta de empoderamiento y desinterés de pobladores como de autoridades. Adicionalmente se identificó que los moradores de la parroquia son conocedores de recetas tradicionales y preparación de platos típicos que son presentados en las festividades, pero, no existe una infraestructura adecuada para su comercialización.
