Coronavirus and Nutrition: Approach for Boosting Immune System in Morocco

The Covid-19 pandemic is a pandemic of an emerging infectious disease, the 2019 coronavirus disease Covid-19, caused by the SARS-CoV-2 coronavirus. The essential protective measures recommended by WHO (2020) to limit the spread of the Coronavirus (Covid-19) limited in the suppression of travel, quarantine and containment. In the first part of this review, we will examine the origin of the coronavirus, the modes of spread and their adverse effects on human health. We will include in our analysis the nutritional importance of the different approaches based on mechanisms to boost the immune system and therefore good viral defense. The immune system helps protect the host against environmental agents such as pathogenic microorganisms (bacteria, fungi and viruses), thus preserving the integrity of the organism. To preserve the defense mechanisms of the organisms, an adequate nutritional state must be maintained with adequate intakes of calories, vitamins, minerals and water which must be continuously provided by a healthy diet. In addition, it is necessary to have nutritional information that will help boost the immune system of people in the fight against Covid-19, nutritional diagnosis and early nutritional management of affected patients must be integrated into the overall therapeutic strategy. Several clinical data have shown that micronutrients like vitamins, including vitamins A, C, D, E, B12, B6 and folic acid; trace elements like iron, zinc, copper, magnesium, selenium, and omega-3 fatty acids like docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) play a major role in supporting the immune system

Identifying effluents from a food processing industry

The agri-food industry in Morocco generates significant volumes of liquid waste, contributing to environmental challenges that directly impact public health. To address this issue, it is crucial to characterize this wastewater comprehensively, enabling the development of suitable treatment strategies to alleviate pollution and potentially facilitate recycling. This study focuses on the identification of effluents from an olive and caper preservation industry, employing physicochemical and bacteriological analyses on raw, decanted, and filtered effluent samples. The findings reveal that the effluent from the olive and caper preservation industry is characterized by high acidity and an exceptionally elevated mineral load. Notably, the application of decantation and filtration methods demonstrates a limited influence, primarily affecting the reduction of suspended solids. Understanding these physicochemical and bacteriological characteristics is pivotal for devising targeted treatment protocols, ensuring effective pollution reduction, and exploring avenues for potential recycling of this agri-food industry wastewater. This research serves as a foundation for informed decision-making in the development of sustainable and efficient wastewater management practices, balancing environmental preservation with industrial needs

Flashing Phenomena in the Case of Two-Phase Flow (Liquid-Gas) in a Vertical Porous Channel

ABSTRACT In this paper, flashing phenomena are studied in the case of water-steam and air outflow in a vertical porous channel . The presence of air, the nature of the porous environment, as well as injected fluid thermo-physics parameters are analyzed. The separate flow model approach which takes the individual properties of air and water separately is considered. On the other hand, we consider that water and its steam are represented as a mixture characterized by the mean properties according to the quality (x)(the ratio of the vapor mass and the total mass). Some results show that the porous environment as well as the presence of air represent a resistance to the water outflow. When the effective permeability (or the relative permeability) decreases, the pressure of injection of water increases to maintain the same flow rate. In this case, a decrease of steam generated is observed

DÉTECTION DU PITCH PAR LES ONDELETTES CONTINUES EN TEMPS RÉEL POUR UN SIGNAL PAROLE BASÉE SUR UN SEUIL ADAPTATIF POUR UNE DÉTERMINATION V/NV.

Une nouvelle méthode de détection du pitch basée sur les transformées d’ondelette continue (TOC) a été développée pour un objectif d’implantation en temps réel qui nécessite un temps d’exécution réduit. Alors on a conçu un algorithme adaptatif comme un outil de détermination V/NV (présenté dans notre travail dans [1]) et se met au début d’analyse d’une trame, si cette trame est voisée on effectue l’analyse sinon on passe directement à la deuxième trame ce qui fournit un temps du calcul réduit (on élimine l’analyse pour un son non voisé d’une trame. Pour plusieurs méthodes, de détection du pitch la décision V/NV est faite après analyse ce qui signifie un vainement de calcul). On a évalué notre méthode sous condition bruité et comparé avec d’autre méthode. Le contour d’évolution du pitch et la décision V/NV présentent un problème complexe sous conditions bruités

Poorly differentiated thyroid carcinoma: a retrospective clinicopathological study

Poorly differentiated thyroid carcinoma (PDTC) is an independent thyroid cancer histotype. In spite of its scarcity, it represents the main cause of death from non-anaplastic follicular cell-derived thyroid cancer. However, given the newness of this entity, few data are available on its clinical behaviour and no explicit consensus sets its treatment. To report the experience of a tertiary medical centre in morocco with PDTC over a period of 7 years. Retrospective study selecting all patients treated for thyroid carcinoma in Nuclear Medicine Department of a tertiary medical centre in Casablanca over seven years period. Patient's files were reviewed for background data, clinico-pathological characteristics, treatment and outcome. Seven patients were included in the study. Patient's average age was 60 years old (30-81) including six women and one man. All patients underwent a total thyroidectomy completed by cervical lymph node dissection in 57% of cases. Mean primary tumour size was 4cm (1-9cm). Patients were classified pT3 in 70% of cases, pT1 and pT2 in 15% each. Vascular invasion was found in 85% of cases. Pathological subtypes found were "insular carcinoma" in 85% of cases. Radioiodine therapy (RIT) was indicated in all cases. Follow-up period ranged between 10 months and 6 years. It showed a complete remission in 57% of cases, persistent disease in 28% of cases and a progressive disease in 15% of cases with a local recurrence. To date, the survival rate is 85%. PDTC is an aggressive thyroid cancer histotype. Treatment remains surgical followed by RIT if the tumour is radioavid. Multimodality therapy is indicated depending on the case and close monitoring is always indicated given the high risk of relapse

Topological phase diagram and saddle point singularity in a tunable topological crystalline insulator

We report the evolution of the surface electronic structure and surface material properties of a topological crystalline insulator (TCI) Pb1-xSnxSe as a function of various material parameters including composition x, temperature T and crystal structure. Our spectroscopic data demonstrate the electronic groundstate condition for the saddle point singularity, the tunability of surface chemical potential, and the surface states' response to circularly polarized light. Our results show that each material parameter can tune the system between trivial and topological phase in a distinct way unlike as seen in Bi2Se3 and related compounds, leading to a rich and unique topological phase diagram. Our systematic studies of the TCI Pb1-xSnxSe are valuable materials guide to realize new topological phenomena.Comment: 10 pages, 7 figures. Expanded version of arXiv:1403.156

Yard-Sale exchange on networks: Wealth sharing and wealth appropriation

Yard-Sale (YS) is a stochastic multiplicative wealth-exchange model with two phases: a stable one where wealth is shared, and an unstable one where wealth condenses onto one agent. YS is here studied numerically on 1d rings, 2d square lattices, and random graphs with variable average coordination, comparing its properties with those in mean field (MF). Equilibrium properties in the stable phase are almost unaffected by the introduction of a network. Measurement of decorrelation times in the stable phase allow us to determine the critical interface with very good precision, and it turns out to be the same, for all networks analyzed, as the one that can be analytically derived in MF. In the unstable phase, on the other hand, dynamical as well as asymptotic properties are strongly network-dependent. Wealth no longer condenses on a single agent, as in MF, but onto an extensive set of agents, the properties of which depend on the network. Connections with previous studies of coalescence of immobile reactants are discussed, and their analytic predictions are successfully compared with our numerical results.Comment: 10 pages, 7 figures.
