description: This short communication studies the physicochemical properties of an abundant natural rock from the Sidi Lamine region of Central Morocco, used as a basic product in several building materials. Using X-ray diffraction (XRD) and scanning electron microscopy coupled with Energy–dispersive X–ray analysis (SEM/EDX), we show that the rock is composed mainly of calcite (CaCO3) and and a small amount of quartz (SiO2). From the spectroscopic data, we can ease the work later on this rock for the development of new building products.

description: Soil properties, such as wetting collapse behavior and permeability, are strongly correlated to the soil microstructure. To date, several techniques including mercury intrusion porosimetry (MIP), can be used to characterize the microstructure of soil, but all techniques have their own limitations. In this study, the features of mercury that penetrated and has been entrapped in the pore network of the specimens through MIP testing were investigated by X-Ray microtomography (X-$μ$CT), in order to give an insight into the geometry of macropores and possible ink-bottle geometry. Two conditions of water content and density were selected for the compacted Maryland clay. The distribution and geometry features of mercury entrapped in the microstructure after MIP were characterized and pore size distributions were also reconstructed. The results suggest that, for the two conditions studied in this paper, macropores were evenly distributed within the specimens, and most of them with a non-spherical shape, and with aspect ratio (ratio between the maximum and minimum thickness along a given segment) smaller than three. Different dominant entrance pore size of macropore was obtained from MIP and X-$μ$CT, due to the specific experimental protocol used in tests and the effect of ink-bottle geometry. Only the large pore bodies with high aspect ratio were imaged in X-$μ$CT, due to the extrusion of mercury during the process of depressurization and subsequent sample preparation for X- $μ$CT. But entire pore space was accessible in MIP. The difference in dominant entrance pore size was more significant for specimens with lower void ratio due to a more pronounced aspect ratio.

description: In this article we design a novel quasi-regression Monte Carlo algorithm in order to approximate the solution of discrete time backward stochastic differential equations (BSDEs), and we analyze the convergence of the proposed method. The algorithm also approximates the solution to the related semi-linear parabolic partial differential equation (PDE) obtained through the well-known Feynman-Kac representation. For the sake of enriching the algorithm with high-order convergence a weighted approximation of the solution is computed and appropriate conditions on the parameters of the method are inferred. With the challenge of tackling problems in high dimensions we propose suitable projections of the solution and efficient parallelizations of the algorithm taking advantage of powerful many-core processors such as graphics processing units (GPUs).

description: In this study, we have developed a new effective study to find solutions for obesity disease by exploring the links between this disease and the CAMKK2 inhibitor by developing a two-dimensional model of quantitative structure-activity relationships (2D-QSAR) for a group of 32 molecules based on pyrimidine and azaindole derivatives, these molecules were subjected to quantitative structure-activity analysis (QSAR) to study, interpret and predict activities using several statistical tools, such as Multiple Linear Regression (MLR), Nonlinear Regression (MNLR) , and principal component analysis models (PCA) which are developed using 32 molecules with a pIC50 between 6.7 and 9.1. The 16 descriptors are calculated for the 32 compounds studied using ACD / ChemSketch and Marvin Sketch software. The best-generated MLR and MNLR models show conventional correlation coefficients R of 0.829 and 0.878, respectively.

description: In this paper, we design a novel algorithm based on Least-Squares Monte Carlo (LSMC) in order to approximate the solution of discrete time Backward Stochastic Differential Equations (BSDEs). Our algorithm allows massive parallelization of the computations on many core processors such as graphics processing units (GPUs). Our approach consists of a novel method of stratification which appears to be crucial for large scale parallelization. In this way, we minimize the exposure to the memory requirements due to the storage of simulations. Indeed, we note the lower memory overhead of the method compared with previous works.

Non-Platonic Autopoiesis of a Cellular Automaton Glider in Asymptotic Lenia

description: Like Life, Lenia CA support a range of patterns that move, interact with their environment, and/or are modified by said interactions. These patterns maintain a cohesive, self-organizing morphology, i.e. they exemplify autopoiesis, the self-organization principle of a network of components and processes maintaining themselves. Recent work implementing Asymptotic Lenia as a reaction-diffusion system reported that non-Platonic behavior in standard Lenia may depend on the clipping function, and that ALenia gliders are likely not subject to non-Platonic instability. In this work I show an example of a glider in ALenia that depends on a certain simulation coarseness for autopoietic competence: when simulated with too fine spatial or temporal resolution the glider no longer maintains its morphology or dynamics. I also show that instability maps of the asymptotic Lenia glider, and others in different CA framworks, show fractal retention of fine boundary detail down to the limit of floating point precision.

description: Sweet almonds are widely grown in both northern and southern hemispheres owing to their economic and nutritional values. Almonds consumption is linked to numerous health-promoting properties. From pomological and biochemical points of view, lipids are the major fraction in almond kernels. The majority of almond compositional research has been focused on chemical composition especially the lipidic fraction. Along with its nutritional value, almond fat has many cosmetic and medicinal uses, which arise from kernel lipids biochemical richness including several essential fatty acids and antioxidants such as tocopherols. The increase of almond production globally encourages almond oil production, which in turn push scientists and growers to select higher oil yielding genotypes and cultivars and to assess oil plasticity under various environments. Genotypic and environmental variations of almond oil have not reviewed before, hence the originality of this review. Peer reviewed literature published in English for almond oil variability confirmed the genotypic dominance in the expression of this parameter with a heritability value of 0.57. Environmental conditions under which almonds are grown account for important variations in kernel oil content. The main environmental factors studied in the literature encompass climatic conditions along with soil moisture. It has been widely reported that moderate water deficit enhances oil accumulation for various commercial cultivars. An inverted effect is observed when soil water deficit become more pronounced. Almond oil content expression is the result of genotypic and environmental variations. Almond oil production must take into account these variations.

description: COVID-19 was first reported in late 2019 in Wuhan, China, and has since spread extensively in worldwide. The World Health Organization recognized this disease as a pandemic on 11 March 2020. During this pandemic, Moroccan population used several medicinal plants for the prevention purposes. The current work focuses on the study of the most medicinal plants used during this pandemic in Morocco. In early March 2020, preliminary information was obtained through interviews with herbalists. In response to the progression of the Covid-19 epidemic, Moroccan's state of health emergency came into effect 20 March 2020. For this reason, survey data was collected with a Google Form. The participants were selected because of their knowledge of the use of medicinal plants. During this study, we identified a total of 23 medicinal plant species belonging to 11 botanical families used during the Covid-19 pandemic. The most important families were that of the Lamiaceae, Cupressaceae and Zingiberaceae. The most used plants were Allium Sativum, Olea europaea, Allium cepa, Zingiber officinale, Thymus maroccanus, Eucalyptus globules, Foeniculum vulgare, Curcuma xanthorrhiza, Phoenix dactylifera, Rosmarinus officinalis, Thymus satureioides, Mentha pulegium and Pimpinella anisum. Information on the biological effects and on the most abundant secondary metabolites in the 23 plants was given. According to several studies the majority of these plants are used to treat many respiratory diseases causing symptoms and signs similar to coronavirus symptoms. These plants have innumerable benefits because of the diversity of the secondary metabolites which they contain. The majority of these compounds, especially essential oils, are well known for their positive biological effects on respiratory functions. But some plants may contain toxic substances which can cause various overdose intoxications and disorders.

Subjects: Treatment, Traditional, Symptoms, Coronavirus.

description: Coronavirus disease is caused by severe acute respiratory syndrome (SARS) and is the causative agent of a life-threatening disease that is of great concern to global public health. Currently, according to the definition given by Morocco's public health of this pandemic: "The symptoms described mainly evoke an acute respiratory infection (fever, cough, shortness of breath), but also breathing difficulties and pulmonary complications of pneumonia type are also described, as well as more severe forms. Digestive and ocular symptoms (conjunctivitis) have also been observed in some confirmed cases ". Human-to-human transmission of coronavirus infection has led to the isolation of patients who then received various drug treatments (chloroquine, lopinavir / ritonavir, teicoplanin, azithromycin, ...) who are likely to be administered are therefore those who allow to fight against its symptoms, on the other hand, the effectiveness of these drugs remains a big problem considering the large number of deaths mentioned in the totality. In the meantime, it's the global race to find a specific drug, stop this pandemic, we will present a traditional Moroccan treatment for fever and flu, the major symptoms similar to those of coronavirus disease, this treatment based on two (2) medicinal plants used in the countryside for several centuries (Since 19th century). May this minireview be helpful for conquering COVID-19 in the near future.

description: This work focuses on MB sorption by hazelnut shell (HN) modiﬁed by zero valent iron and silver bimetallic nanoparticles. The purpose of this study is to understand the mechanisms that govern the elimination of MB and to find a suitable kinetics model of removal. Spectroscopic studies including FTIR, (TG-DSC), Methylene blue, Iodine number and effet of pHZPC were used for its characterization. Equilibrium data was examined using a comparison of linear Langmuir, Freundlich and Temkin isotherm models. The Freundlich and Langmuir isotherm provided the best fit to the experimental data for MB as indicated by the values of the regression coefficient. The kinetic rates were modeled by using the Lagergren-first-order, pseudo-second-order, Elovich and Intraparticle diffusion model. The pseudo-second-order model was found to explain the adsorption kinetics most effectively. The presence of intra-particle diffusion mechanism was prominent, although it was not the sole rate-determining step. The results showed that HN, HN-Fe0 and HN-Fe0/Ag0, can be effective for removing MB from solution.

description: This work examines the distributions and comparison of trace elements in Moroccan and Indian henna samples. Multivariate statistical methods involving principal component analysis and hierarchical cluster analysis are applied. The measurements were performed using 22 elements (Al, As, Ba, Ca, Cd, Ce, Cr, Cu, Er, Fe, K, La, Li, Mg, Mn, Na, Ni, Sm, Sr, Ti, Y, Zn) at µg.g-1 level determined by ICP-OES. The coefficients calculated for samples indicated strong positive correlations among firstly K, Mg, and Li, on the hand La and Ba, on the other hand Al and Fe and finally Ti and Er. These strong correlations between these variables show the similarity of the phenomena at the origin in henna samples. Also, negative correlations between K, Mg and Li with Ba then La, which indicates that these elements have different origins, the same result showed by Fe and Ce. The multivariable analysis indicates that three principal components (PC) were significant with eigenvalues higher than 1, contributing 100% of the observed variance. Thus, principal component 1 and principal component 2 showmajor contributions, whereas principal component 3 has a relatively lower effect. The same results obtained by hierarchical cluster analysis.

description: In this paper, physicochemical and nutrition values (moisture, ash, nonfat solids, total solids, protein, fat, lactic acid, pH, and total sugar contents) in several pasteurized milk and long-life milk samples (11) sold in Misurata city-Libyan supermarkets have been evaluated. Several techniques have been used for these determinations. Generally, the concentrations of these parameters were varied significantly depending upon the type of the milk type. The levels of proteins, fats, total acidity, and total sugars were as follows: 2.43 – 3.50 %, 0.25 – 3.50 %, 0.13 – 0.18 %, and 2.96 – 4.39 %, respectively. However, the levels of the investigated parameters were in the acceptable range reported by the Libyan standard specifications. Also, our results were similar to those reported by several researchers. Finally, further investigations should be carried out to monitor the quality of a greater number of milk samples from various companies in Libya and to confirm their quality.

description: An inductively coupled plasma atomic emission spectrometry (ICP-AES) method was developed for the simultaneous determination of major, minor and trace elements in lipsticks purchased from Valencia markets. A comparative study between microwave-assisted digestion with HNO3/H2O2 and dry ashing with Mg(NO3)2/MgO, as ashing aid, was performed in order to provide the highest sensitivity and to maximize the number of the analytes to be quantified. Microwave assisted digestion can be considered better than dry ashing method for avoiding Ba losses and providing data regarding Mg contents. Limit of detection values, equal or lower than few mg g-1, were obtained for all the elements under study. To assure the accuracy of the whole procedure, the recovery of the proposed microwave assisted digestion method was evaluated using spiked samples at different concentration levels from 40 to 1600 mg L-1. Quantitative average recovery values were obtained for all the elements evaluated, demonstrating the suitability of this methodology for the determination of mineral elements in lipstick samples. Finely, results obtained for the analysed samples were compared with those found in the literature to fuelling the lack of information about many elements existing in the lipsticks.

description: The accumulation of heavy metals (Cd, Pb, Cr, Li...) in soils, especially agricultural soils, can cause serious problems for the environment and organisms. The accumulation of these Heavy Metals is mainly due to intense human and industrial activities. These soil contamination problems can be partially solved by the application of phytoremediation technologies or phycoremediation using algae to complex and remove pollutants from the environment. In this study we evaluated the role of a macroalgae Corallina officinalis on the mitigation of chromium toxicity in the bean crop (Vicia faba L.). Our results showed that the addition 5% of Corallina officinalis improved growth parameters and chlorophyll content in bean leaves, and that in the presence of chromium, and reduced chromium toxicity on faba bean crop.

description: This study evaluates antimicrobial and cytotoxic activities of the marine red algae Bornetia secundiflora collected from the Atlantic coast of Sidi Bouzid El Jadida-Morocco. Antibacterial and antifungal activities were tested in methanol, chloroform, acetone, hexane and water extracts against Staphylococcus aureus, Bacillus subtilis, Bacillus thuringinsis, Bacillus cereus and against fungi Candida albicans and Candida tropicalis. The best antibacterial activity was obtained in methanolic extract and S. aureus was the more sensitive, while, a weak antifungal activity was observed. Concerning the cytotoxic activity, dichloromethane/methanol (50:50) extract of Bornetia secundiflora was evaluated using test of brine shrimp lethality for larvae then tested on KB, HeLa and k562 cells lines.The highest cytotoxic activity was found against KB cell lines.
