Full textAbstract:
Recent climate change effects worsened water scarcity in Morocco and forced the country to seek alternative water resources such as domestic and industrial wastewater. In this context, we assessed the treatment efficiency of wastewater treatment plants (WWTP) of the BeniMellal-Khenifra region based on physicochemical and biological parameters. Vegetation cover evolution near WWTPs was also analysed using satellite images (Landsat TM and OLI). Six WWTP were evaluated based on treated water quality and a survey of nearby farmers and residents. Results showed treated wastewater is in line with Moroccan standards, and can be reused for irrigation and aquaculture without harmful effects. The survey pointed to the Boujaad WWTP as a model in the region. The vegetation cover evolution before and after WWTP existence showed an important improvement of cultivated lands. As a conclusion, wastewater reuse will allow the BeniMellal-Khenifra region to secure agricultural irrigation to safeguard freshwater quantities and quality despite climate change.

Like the other Moroccan territories, Khenifra region faces many problems in household waste management, due to produced waste quantities, the insufficient infrastructure and the low level of environmental education. Khenifra region contain a diversified and fragile natural environment. In this work, we used the social approach that aims to diagnose the current state of waste management in the study area and in order to propose appropriate solutions for a successful management, as results, the existence of several deficiencies and constraints in the daily operations of collection and landfilling. Surveys and field visits have been carried out showed that the human and material resources used in the west management operation are not sufficient and not respect the environmental conditions. Facing these constraints require, an effective strategy for management of household waste in this territory has been developed to ensure a better collect and treatment. Thus, our proposed strategy cannot succeed without population involved, it requires collaboration between municipalities, delegated companies and citizens as well.

Full textAbstract:
One of the most important challenges in the authentication of olive oil is the determination of the geographical origin of virgin olive oil. In this work, we evaluated the capacity of two spectroscopic techniques, UV-Visible and ATR-FTMIR, coupled with chemometric tools to determine the geographical origin of olive oils. These analytical approaches have been applied to samples that have been collected during the period of olive oil production, in the Moroccan region of Beni Mellal-Khenifra. To develop a rapid analysis tool capable of authenticating the geographical origin of virgin olive oils from five geographical areas of the Moroccan region of Beni Mellal-Khenifra, UV-Visible and ATR-FTMIR spectral data were processed by chemometric algorithms. PCA was applied on the spectral data set to represent the data in a very small space, and then discrimination methods were applied on the principal components synthesized by the PCA. The application of the PCA-LDA method on the spectral data of UV-Visible and ATR-FTMIR shows a good ability to classify olive oils according to their geographical origin with a percentage of correct classification that represents 90.24% and 85.87%, respectively, and the processing of the spectral data of UV-Visible and ATR-FTMIR by PCA-SVM allows differentiating correctly between five olive oils with a correct classification rate of 100% and 97.56, respectively. This study demonstrated the feasibility of UV-Visible and ATR-FTMIR fingerprinting (routine technique) for the geographical classification of olive oils in the Moroccan region of Beni Mellal-Khenifra. Such developed methods can be proposed as alternative and complementary methods to authenticate the geographical origin of virgin olive oil.

Agriculture in the region of Beni Mellal-Khenifra, Morocco relies on irrigation from rain and dams, but recently there has been a lack of precipitation which may negatively affect crop growth. This has made accurate precipitation forecasts even more important for farmers, as they need this information to make informed decisions about their crops. However, a lack of data-driven research utilizing past data presents a challenge for the development of such research and leaves farmers relying solely on weather forecasts from TV, which cannot relied upon in systems such as irrigation. The objective of this paper is to propose various approaches for forecasting precipitation in the region of Beni Mellal-Khenifra using big data analytics and machine learning techniques. The study made use of Apache Spark, a big data analytics tool, and five machine-learning algorithms: Lasso regression, ridge regression, elastic net, auto regressive integrated moving average, and random forest. These algorithms were applied on dataset of daily rainfall from 2000 to 2015 to forecast the amount of precipitation in the region. The results of the study showed that the random forest algorithm had the lowest mean absolute error, making it the most effective at forecasting precipitation in the region.

Abstract Khenifra region is rich in geological resources, which attracted a lot of investment, especially the quarrying. The Grou River watershed contains a lot of quarries of alluvial material extraction which causes negative impacts on its environment such as landscape modification, water quality degradation, dust emission and, soil erosion. The evaluation of water quality by measuring physicochemical parameters showed a deterioration of its quality in the downstream area compared to the upstream area. To respond to this situation, we suggest a set of mitigation measure and propose the respect of monitoring and surveillance plans.

Abstract Water contaminated by microorganisms and chemical molecules is a cause of disease for humans and the environment. For this reason, we have assessed the microbiological quality and metallic trace elements of groundwater used by the rural population of the Khenifra province, Morocco. Two groundwater sampling campaigns were carried out during the period February/August 2021, studying physico-chemical parameters such as temperature, electrical conductivity, dissolved oxygen, and ph. Then, the metallic trace elements were analyzed: lead (Pb), copper (Cu), nickel (Ni), manganese (Mn), iron (Fe), and zinc (Zn). In addition, the samples taken for the bacteriological study were filtered and introduced in a growth medium for the research and enumeration of total aerobic mesophilic germs vary from 1 to 30.103CFUs/ml, total coliforms (1 to 3x102 CFUs/100ml), Escherichia Coli(1 to 3x102 CFUs/100ml)and intestinal enterococci(1 to 290 CFUs/100ml). The analysis was carried out according to the recommendations of Moroccan standards. It is interesting to note that the groundwater in the Khenifra region is contaminated with pollutants and can cause a health risk for the inhabitants.

Despite advances in modern medicine, limitations persist. In response, scientific research is revisiting the benefits of natural products, particularly homeotherapy. Limited healthcare access in developing countries is another factor driving the population towards traditional medicine. Herbal medicine is viewed as a viable alternative, especially among pregnant women, despite limited safety data. This study aims to document the use of medicinal plants by pregnant and postpartum women in Beni Mellal-Khenifra region and identify associated factors. A cross-sectional survey was conducted with 400 postpartum women in the maternity ward of the regional hospital of Beni Mellal. Most women (63.75%) reported using medicinal plants during pregnancy, labor, and after dilevery. Significant correlations were found between medicinal plants usage and family structure, residence, and education level (p<0.05). The study identified 20 plant species used for various health issues, with Lepidium sativum, Peganum harmala, and Trigonella foenum-graecum being the most common. Medicinal plants were used for dietary, cosmetic, and therapeutic purposes, with gastrointestinal disorders, urinary tract infections, and anemia being the most frequently treated conditions. Adverse effects were reported by 5.88% of users. Family and friends constituted the primary source of information (34.73%). Pregnant women in the Beni Mellal-Khenifra region widely utilize herbal medicine for various purposes, despite the potential risks associated with certain remedies. There is a pressing need for enhanced education and awareness regarding the safe use of herbal medicine during pregnancy.

The outbreak of COVID-19 has made a substantial positive impact in educational settings, urging teachers to use innovative online ways of teaching and making numerous online platforms, including Microsoft Teams, Google Meet, Google Classroom, video communication applications, and many other tools accessible for students. However, the online learning setting has spawned a variety of challenges for both learners and teachers, ranging from technical problems to poor training. As a matter of fact, learners, educators, and practitioners have different attitudes toward the effectiveness of online learning. Considering this, this study investigates the impact of implementing online learning on students' grammar performance in Morocco. It does so by assessing the control and experimental groups' performance during five-week experimentation. The study population was 11th-grade secondary school students in Tazizaoute High School, El Kbab, Khenifra, Benni-Mellal-Khenifra Region. The participants were randomly and equally assigned to the control group (N=30), taught through face-to-face learning, and the experimental group (N=30), taught using online learning via Microsoft Teams. To collect quantitative data, grammar pre- and post-tests were employed to measure the grammar performance in both groups before and after the treatment. Both descriptive and inferential statistics (Independent T-Test) using SPSS-26 were used to analyse the data. The findings revealed a statistically significant difference between the two groups favouring the control group.

Full textAbstract:
Drought and water scarcity are resulting from the effects of climate change during recent decades. The region of Beni Mellal Khenifra, by the nature of its economic activities based particularly on agriculture and the availability of water resources, is considered among the most vulnerable regions to the effects of climate change in Morocco. In this paper, we analyzed the impact of climate change on the three largest dams in the region (Hassan first, Bin El Ouidane and Ahmed El Hansali), based on statistical data from five stations over 1990-2020. We used Normalized Precipitation Index (SPI) to characterize climatic drought, the Mann-Kendall test to assess the trend of temperature changes, Kendall’s tau and linear regression to detect the relationship between climatic parameters (temperature and precipitation) and water supplies from the three dams. Standardized Precipitation Index (SPI) results showed that the region underwent a significant rainfall deficit between 19911995, 2000-2003, 2005-2008, and 2017-2020. Their intensity varies from moderate to severe type. Moreover, temperature values obtained by Mann– Kendall test showed an increasing trend for all stations. Correlation analysis of rainfall and temperature with inflow dams showed that the mean annual inflows dams are directly proportional to the yearly average SPI increase.

Full textAbstract:
Euphorbia resinifera O. Berg, also called Euphorbusresin, is a species belonging to the Euphorbiaceae family. It is endemic to the Beni Mellal Khenifra region and extends discontinuously between El Ksiba and Demnate. Currently, this plant is known as a meliferous species and its product is considered as a terroir product with a Protected Geographical Indication (PGI). However, few studies have conducted on its ecology and particularly its mapping in relation to the environmental conditionswhere it thrives. That’s why in this study, we tried to establish, for the first time in the region of Beni Mellal, a distribution mapping of E. resinifera according to the ecological needs of the plant, the exploration of high-resolution satellite imagery and on the field by observing a representative sample of the study area. Results showed that it spread from Demnate to Elksiba in the Atlas piedmont area but appears as scattered individuals from Demnate to AitOurir due to a complexity of factors mainly related to the soil characteristics, paleogeography and the climate exacerbated by the negative results of anthropogenic impacts. It extends also into the central high Atlas valley as small isolated units which reach 1900 m of altitude. This could explain why other ecological requirements should be considered in terms of the distribution of this endemic species in the context of climate change.

The protection of plant food resources contributes to safeguarding their nutritional value, the culinary heritage as well as the sustainability of the traditional food that uses them. To contribute to the knowledge of wild edible plants (WEPs) used in traditional diet among the population of 7 communes in Khenifra province in a mountainous region of Morocco, an ethnobotanical survey was conducted on 206 local adult respondents, of both sexes, in rural (70%) and urban (30%) areas using a questionnaire and focus groups. Information on sociodemography, knowledge of WEPs and their current and past indigenous food and medicinal uses, culinary knowledge, recipes for their preparation as well as their toxic effects were collected. The results show a great food variety of more than 90 WEPs belonging to 40 families and that the local population still often uses different WEPs on a daily basis as food, in therapy or other uses in the study area. Over 50 traditional recipes were recorded, consumed presently and in the past with recipes consumed during times of food shortage. The study also reports that the local population has ethnobotanical information and knowledge of traditional cooking techniques allowing the safe use of WEPs. Dietary diversity linked to knowledge of biodiversity, traditions and culinary culture to use WEPs is observed in the study population. However, this knowledge is in decline, especially among younger generations, which draws attention to the importance of documenting and safeguarding this wealth.

Full textAbstract:
This paper evaluates the ability of a natural rock found in Morocco to remove the pollutant properties of methylene blue (MB) dye. In this regard, the experiments were conceived to test the hypothesis that the rock native of the country’s region of Khenifra can be used as a new abundant adsorbent to remove cationic dyes from water through the adsorption technique in order to avoid extra cost and contribute to the valorization of this material. For this, several factors such as pH of the solution, granulometry, mass of adsorbent, initial dye concentration and stirring rate were tested. The adsorption kinetics process was tested through three models, namely, the pseudo-first-order model, pseudo-second-order model and the intraparticle diffusion model, to predict which type of adsorption is best suited in the removal of dye pollution. The batch study proves that only the granulometry (G ≤ 63µm = 91%, G ≤ 80µm = 88.4% and G ≤ 100µm=70.7%) and the adsorbent mass (the more the mass of the adsorbent increases the more the elimination is achieved) can influence the elimination rate of our rock. Meanwhile, the data of the adsorption kinetics test show that the experimental adsorption could be described by the mechanism of the pseudo-second-order model (correlation coefficients near the unit ‘R 2 = 0.99’ ), confirming chemical sorption as a rate-limiting step of the intraparticle diffusion mechanism. According to the results of this study, the rock collected from the area of Khenifra can be used as a new and efficient adsorbent in the field of wastewater treatment.

In Morocco, where cancer is a major public health problem, the characteristics of cancer in the Beni Mellal-Khenifra region of Morocco are unknown. Our objective was to establish the epidemiological profile of cancer in this region and the main risk factors influencing cancer. We conducted a cross-sectional study, including all types of cancer, with a sample of 100 patients at the Beni Mellal regional oncology center. Data collected in June and July 2021 using a questionnaire, pre-tested, and analyzed using SPSS and Excel. The questionnaire included sections on cancer-related clinical characteristics and other items related to cancer risk exposures. Gyneco-mammary cancers occupied the first position (49%). The most common localization of cancer in women was breast cancer, with a proportion of 63% of cases recorded during the period studied. In men, lung cancer was the most frequent location at 17%. We found some possible risk factors for cancer: tobacco and alcohol use, dietary habits, use of hormonal contraceptive methods, low income, pollution, sun radiation, exposure to asbestos, family history of cancer, and diseases associated with cancer. Women’s cancers are very common in the region. Several factors are responsible for this frequency. These results suggest several avenues for further research.

Abstract The industrialization of the agricultural sector increases the use of pesticides, which are composed of chemical substances, such as herbicides, fungicides, insecticides, acaricides, nematicides, and rodenticides, that are adapted to the control of undesirable plants and animals. All these phytosanitary products have varying degrees of toxicity, which risks human life. This study aimed to make an inventory of the pesticides used in the irrigated perimeter of Beni Moussa and Beni Aamir in the Beni Mellal-Khenifra region. The data collection through questionnaires took place between January and February 2016 and covered all the study areas. The questionnaires are focused on the mode of packaging management, sale and purchase of pesticides. The results demonstrated the existence of different pesticides and active substances used for crop protection in the region. Among 63 molecules, 14 active substances were detected, where the active substances are not approved by the world health organization, which considers it as carcinogenic substances. During phytosanitary treatments by farmers, these active substances come into direct contact with the soil, presenting a permanent risk to the environmental compartments, including groundwaters.

The purpose of this study is to determine the total content of phenols, flavonoids, and condensed tannins, as well as on the antioxidant activity of the extract, and their fractions were measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), phosphomolybdate reduction (or total antioxidant capacity), and cyclic voltammetry (CV). The hydromethanolic extract of Salvia officinalis showed the highest values of total phenolic (176 mgGAE/g of extract) and condensed tannins (162.53 mgEC/g of extract) from the Boulemane and Khenifra regions, respectively. The results showed that the best DPPH assay was found in the ethyl acetate fraction of Salvia officinalis leaves of the Boulemane region (IC50 = 0.002 mg/ml). For the ethyl acetate and butanolic fractions of Salvia officinalis leaves, those collected from different regions have a better reducing capacity (EC50 = 0.021 mg/ml, respectively). For the total antioxidant capacity, the best activity was found in the aqueous fraction of Salvia officinalis leaves of the Boulemane region (108 mgGAE/g of extract). By the cyclic voltammetry method, hydromethanolic extract of Salvia officinalis leaves from the Boulemane region showed an important result (288.8 mgGAE/g). There was a positive correlation between total phenol content (TPC), condensed tannin content (TCT), and total antioxidant capacity (TAC) (r = 0.932, r = 0.896, respectively). The main compounds that have been identified in the hydromethanolic extract of Salvia officinalis are ascorbic acid, gallic acid, 4-hydroxybenzoic acid, tannic acid, and rutin. Due to their antioxidant property, the leaf extracts from Salvia officinalis are used as natural preservative ingredients in food and/or pharmaceutical industries.

In Morocco, where cancer is a major public health problem, the characteristics of cancer in the Beni Mellal-Khenifra region of Morocco are unknown. Our objective was to establish the epidemiological profile of cancer in this region and the main risk factors influencing cancer. We conducted a cross-sectional study, including all types of cancer, with a sample of 100 patients at the Beni Mellal regional oncology center. Data collected in June and July 2021 using a questionnaire, pre-tested, and analyzed using SPSS and Excel. The questionnaire included sections on cancer-related clinical characteristics and other items related to cancer risk exposures. Gyneco-mammary cancers occupied the first position (49%). The most common localization of cancer in women was breast cancer, with a proportion of 63% of cases recorded during the period studied. In men, lung cancer was the most frequent location at 17%. We found some possible risk factors for cancer: tobacco and alcohol use, dietary habits, use of hormonal contraceptive methods, low income, pollution, sun radiation, exposure to asbestos, family history of cancer, and diseases associated with cancer. Women’s cancers are very common in the region. Several factors are responsible for this frequency. These results suggest several avenues for further research.

Full textAbstract:
Honey is valued not only for its taste and nutritional properties but also for its health benefits, primarily due to its phenolic compound content. Environmental and biological factors influences this content. This study investigates the total polyphenol content of monofloral honey varieties from the Beni Mellal-Khenifra region and its relationship with botanical origin, geographic location, color, and harvesting period. The results showed highly significant differences in total phenolic content among honey samples with varying botanical and geographical origins (p < 0.0001). The study revealed a strong correlation (r= 0.985*, p<0.05) between total phenolic content and the location of honey collection. Honey from lower altitudes, such as citrus and anis honey, showed lower total polyphenol content levels (13.53 ± 0.004 and 19.10 ± 0.004 mg EAG/100g, respectively), while honey from higher altitudes, such as euphorbia and carob honey, exhibited higher total phenolic content levels (30.61 ± 0.009 and 28.62 ± 0.003 mg EAG/100g, respectively). Additionally, a highly significant correlation was observed between total phenolic content and honey color (r = 0.996**, p<0.01), indicating that darker honey contains higher phenolic levels. Conversely, no significant association was found between total phenolic content and harvesting period (r = 0.486, p>0.05). These results highlight the impact of environmental factors on honey’s phenolic composition and underscore the importance of considering geographic and botanical influences in honey quality assessment.

ABSTRACT Several research studies have been devoted to study the links between emotional disorders and learning disabilities. However, very minimal of this research has focused on dyslexic students. Objective: The objectives of this study were as follows: (1) to assess self-esteem, anxiety, and depression in dyslexic Arabic-speaking children and adolescents and (2) to describe psychiatric comorbidities in these subjects by comparing them to their non-dyslexic peers. Methods: In total, 205 students (56 dyslexics and 149 good readers), pursuing their education in ordinary schools in the Beni Mellal-Khenifra region of Morocco responded to Taylor’s Self-Assessment Scale of Anxiety, Beck’s Depression Questionnaire, and the Coopersmith Self-Esteem Inventory (SEI). Results: Overall, dyslexics were more anxious, more depressed, and had disturbed self-esteem compared to their non-dyslexic peers. The percentage of psychiatric comorbidity was higher in the dyslexic group. Conclusions: The results of this study highlight the need for a multidisciplinary approach that integrates emotional needs assessment into the rehabilitation care of dyslexic children and adolescents.

Full textAbstract:
Soil salinisation is a phenomenon considered to be a real threat to natural resources in semi-arid climates. The phenomenon is controlled by soil (texture, depth, slope etc.), anthropogenic factors (drainage system, irrigation, crops types, etc.), and climate factors. This study was conducted in the watershed of Oued El Abid in the region of Beni Mellal-Khenifra, aimed at localising saline soil using remote sensing and a regression model. The spectral indices were extracted from Landsat imagery (30 m resolution). A linear correlation of electrical conductivity, which was calculated based on soil samples (ECs), and the values extracted based on spectral bands showed a high accuracy with an R2 (Root square) of 0.80. This study proposes a new spectral salinity index using Landsat bands B1 and B4. This hydro-chemical and statistical study, based on a yearlong survey, showed a moderate amount of salinity, which threatens dam water quality. The results present an improved ability to use remote sensing and regression model integration to detect soil salinity with high accuracy and low cost, and permit intervention at an early stage of salinisation.

Full textAbstract:
SummaryThe main characteristics of Beldi (meaning “native” in Arabic) poultry raised in rural areas were studied in the Khenifra Region through extensive surveys.Beldi chickens have large phenotypic variability. Black, brown, grey and white colours, pure or mixed, are frequently observed in chickens' featherings while turkeys are predominantly bronze. Plumage types were fairly homogeneous in both species. Single combs and dented combs were respectively predominant in chicken hens and roosters.Sexual maturity was reached at 154 days for roosters, 168 for hens in chicken, around 217 days for toms and 231 for turkey hens. The age at first egg averaged 5.8 months for hens and 8.4 months for turkey hens. The number of eggs laid per hen per year was 78 for chicken and 69 for turkey. Hatchability rate was 78 and 80 percent for chicken and turkeys, respectively. Diseases were the main cause of mortality, which could affect up to 77 percent of chicken flocks.Few preliminary urgent steps for the conservation of Beldi poultry are discussed with other production improvement proposals.

Full textAbstract:
Since it first appeared in 2022, the phenomenon referred to as Colony Collapse Disorder (CCD) has affected several regions of Morocco to varying degrees. In order to assess the possible impact of pesticides on the appearance of this syndrome, we conducted a study aimed at evaluating the impact of pesticide use on the emergence of this syndrome through a year-long survey involving 160 beekeepers in the Beni Mellal–Khenifra Region (BKR) who also experienced an unprecedented desertion of hives during the same period. The majority of surveyed beekeepers practice mixed (45%) or migratory beekeeping (42%) and provide supplementary feeding (83.75%) to support their bees. Nearly 37.5% of the hives are located near crops treated with pesticides, exposing the bees to these chemicals. The results showed that the majority of beekeepers reported a cessation of queen laying (74.38%), high mortality rates among worker bees (81.25%), drones (65.63%), and queens (61.88%). Abnormal behaviors such as immobility with trembling (42.50%), reduced flights (47.50%), and disoriented navigation (28.75%) were also observed. Correlation analyses indicate that proximity to treated crops significantly increases the risk of queen laying cessation (Odds Ratio 6.0) and a reduction in waggle dances (Odds Ratio 2.41). Extended foraging flights show a borderline statistical significance (Odds Ratio 2.33), suggesting a disruption of natural food sources. These results highlight the potential impact of pesticides on colony health and bee behavior, pointing out the need to adapt beekeeping practices and implement protective measures against pesticides.

By the diversity of its soil and climatic factors, Morocco offers a flora particularly rich in aromatic and medicinal plants (MAP). In order to obtain the most information about the flora (flowering times, fruiting, harvesting and their main uses in traditional medicine), a study was conducted in the mountainous Khenifra region. A survey of users of MAP (rural population, herbalists arborists) has been undertaken and was completed by field observations and sampling at different stages of growth. The results showed a range of indigenous and diversified MAP belonging to 10 botanical families (Lamiaceae, Asteraceae, Rosaceae, Chenopodiaceae, Papaveraceae, Caryophyllaceae, Cupressaceae, Rutaceae, Anacardiaceae and Zygophyllaceae). The flowering period of all species, according to the local community surveyed, spread from February (2%) to September (12%), with a significant concentration from April to June (65%). The highest rate of fructification occurred in June-July (64%). The harvesting period of the main MAP from this mountain area stretches mainly from March to April (61%). The mode of propagation stated varied among species, and concerned mainly replication by seeds (53%) and cuttings (24%). Regarding the use of these indigenous MAP as traditional medicines, all plant parts are used, especially leaves, flowers and stems.

Full textAbstract:
The objective of the present work is to evaluate the relationship between the edapho-climatic conditions of the cultivation environment and the variability of olive productivity, yield, and quality of olive oil in orchards of the Moroccan Picholine (PM) population variety (Olea europaea L.). This work was carried out on different agricultural territorial units (agroecosystems) of the Beni Mellal-Khenifra region with a semi-arid climate during four agricultural seasons (2016/2017 to 2019/2020). For this purpose, the relevant agronomic and agro-biochemical parameters were studied, namely the stage of maturity, fruit and olive oil yields and quality indices. The data treatments of the results were performed according to descriptive and affiliated statistics by analysis of variance (ANOVA). We have found significant correlations (according to Pearson's R) between agroecosystems, particularly for weight of crude olives produced per hectare and temperature (R= 0.803), olive yield and humidity (R= 0.654), olive oil yield and temperature (R= 0.837), olive oil richness and humidity (R= -0.622), as well as the qualitative characteristics of the extracted oils, through the levels of free acidity and peroxide value (R = 0.467). These results confirm that in the studied semi-arid environments, the properties of the biotope of the cultivated olive groves, combined with the interannual agroclimatic variability, effectively influence the productivity of the olive trees, the oil production and the chemical and organoleptic quality of the extracted olive oil

The objective of this study was to identify new bioactive substances through the phytochemical study and evaluation of the antibacterial activity of the essential oils of Tetraclinis articulata (Vahl). Harvested in April 2016, in the region of Khenifra (Middle Atlas-Morocco). Separate of hydrodistillation extracts of the three organs (branches, leaves and fruits) of Tetraclinis articulate were performed. The yields of essential oils are 0.92% for fruits; 0.41% for branches and 0.61% for leaves. The GC/MS analysis allowed the identification of 33 compounds in essential oil leaves, 20 compounds in excess fruits and 58 compounds in branches. The main compounds are bornyl acetate (38.54%) and α-pinene (6.71%) for leaves. α-pinene (22.12%); 13-epi-mannol (3.58%) and retinol (3.44%) for branches. Bornyl acetate (19.96%); α-pinene (12.47%) and retinol (11.98%) for fruits. The antibacterial properties of the essential oil of leaves of Tetraclinis articulata (Vahl) were tested in clinical bacterial strain. The essential oils inhibit the growth of Escherichia coli, Staphylococcus aureus and Klebsiella pneumoniae at 1.2 µl/ml; 2.4 µl/ml and 9.7 µl/ml respectively. Indeed, the resistance of bacteria to antibiotics is known for its adverse effects on human health, to escape this problem, it is necessary to exploit the antibiotics from aromatic and medicinal plants.

This study was realized in the north-east of the plain of Tadla, in the region of Beni Mellal-khenifra, Morocco. The main aim of this research is to establish the geometry and hydrogeology characteristics of the region's aquifer system, based on the results of analysis and interpretation of deep-drilling data, and on gravimetric and electrical survey measurements. First, the regional gradient was determined, then the initial data was extracted, and based on the extracted data, we created the gravity map of the Bouguer, where the anomalies are clearer. The examination of the Bouguer anomaly's gravity map reveals the existence of a regional gradient. These anomalies are typically found in outcrop areas of the basement and differences in thickness of the sediment cover in the study area. The Electrical survey measurements, and the interpretation of the deep-drilling data, confirm the results of gravimetry survey, after applying different techniques such as horizontal gradiometer and upward extension, on the Gravimetric map. The founded results allowed us to draw up a structural map showing the system faults, which is accountable for the study area structure. The structural map is a very useful tool to guide future hydrogeological researches in the plain of Tadla.

This study concentrates on assessing the insecticidal attributes of the γ-Al2O3 nanoparticles derived from the remnants of Mentha pulegium, which include essential oil, ethanolic extract, and plant waste. The synthesis of the γ-Al2O3 nanoparticles was executed using a direct sol-gel procedure, affirming the crystal structure according to extensive physicochemical analyses such as UV-Vis, XRD, FTIR, and SEM. Evaluation of the insecticidal activity in vitro was conducted against Xylosandrus crassiusculus, a pest that infests carob wood, utilizing strains from diverse forests in the Khenifra region, situated in the Moroccan Middle Atlas. The lethal doses 50 ranged from 40 mg/g to 68 mg/g, indicating moderate effectiveness compared to the commercial insecticide Permethrin. Optimization of the conditions for the efficiency of the γ-Al2O3 nanoparticles was determined using experimental plans, revealing that time, humidity, and temperature were influential factors in the lethal dose 50 of these nanomaterials. Moreover, this study encompasses the establishment of correlations using Principal Component Analysis (PCA) and Ascending Hierarchical Classification (AHC) among various geographic, biological, and physical data, amalgamating geographic altitude and γ-Al2O3 nanoparticle insecticide parameters, as well as the attributes of the mechanical tests conducted on the carob wood affected by insects. The correlations highlight the close connections between the effectiveness of the insecticide, mountain altitude, and the mechanical parameters that were examined. Ultimately, these nanoparticles demonstrate promising potential as alternative insecticides, thus opening up encouraging prospects for safeguarding against carob wood pests.

The Beni Mellal-Khenifra region in Morocco boasts one of the largest forested areas in the country, rich in resources that remain underutilized. Among these resources is the Chamaerops humilis L. fruit, which is the focus of this study. Despite its potential value, the fruit has been largely overlooked. In this study, we comprehensively examined the physical-chemical, phytochemical screening, and sensory attributes of Chamaerops humilis L. fruit. Physical analysis revealed variations in fruit size, weight, providing insights into factors influencing these characteristics. Chemical analysis unveiled the fruit's moderate titratable acidity, mildly acidic pH, substantial dry matter content, and noteworthy ash content, indicative of its nutritional composition. The extraction of phenolic compounds total phenolic content TPC, total flavonoid content TFC and antioxidant DPPH (IC50) activity was optimized using simplex centroid design using various extractor solvents (acetone, water and methanol) as well as their combinations in pairs (binary) and threes (ternary). The outcomes showed that the best combination for achieving the highest levels of TPC and TFC, along with enhanced antioxidant activities was the binary acetone-water mixture. Sensory evaluation indicated a moderately acceptable taste, well-received color, and other organoleptic qualities, offering valuable insights into consumer preferences. Furthermore, Fourier transform infrared spectroscopic method with attenuated total reflectance (FTIR-ATR) spectroscopy identified seven distinctive bands in the fruit pulp spectrum, providing evidence of proteins, carbohydrates, lipids, and unique functional groups within the fruit. These findings collectively enhance our understanding of the multifaceted utility of Chamaerops humilis L. fruit, highlighting its potential in nutrition and traditional medicine, and emphasize the importance of further research to explore its applications and promote dietary diversity and well-being.

Objectives. Congenital malformations originate from the genetic constitution of the embryo or from an extrinsic defect during its in-utero development. The most common causes of congenital anomalies are teratogenic agents, specifically the teratogenic plants (TP). In this context, we undertook a cross-sectional study in order to assess the prevalence of TP usage by pregnant women before and during pregnancy in Morocco. Material and methods. This study was conducted in seven health facilities providing ante-natal care in the Beni Mellal-Khenifra region, central Morocco. The study focused on a population of pregnant women (N=624) in their last trimester of pregnancy, spanning a four-months period from February 1 to May 30, 2022. Results. In total, 13 different TP were identified. 92% of pregnant women reported that they were used with TP before pregnancy, this percentage decreased to 75% during pregnancy. For newborns after childbirth, stillbirth represents 0.7% of pregnancies. Furthermore, there were 17 newborns (2.8%) affected. The use of TP during pregnancy showed a significant association with the economic level of pregnant women (p < .05), medical insurance (p < .05), parity (p < .05), the type of pregnancy (programmed or not) (p < .05), and stillbirth (p < .05). Furthermore, a knowledge gap and dangerous practices related to TP were detected among participants. Conclusions. This study reveals high prevalence of TP used just before and during pregnancy which present a danger to the health of mothers and their newborns, requiring an urgent action to raise public awareness of the harmful effects of these TP.

Full textAbstract:
Overuse of chemical pesticides has been linked to mammalian toxicity, environmental contamination, and bioaccumulation. Nanopesticide research, introduced relatively recently, is an emerging field that can be defined as application of nanotechnology for crop protection. Nanopesticides have been proven to be more effective in reducing pest populations and plant infestation levels than bulk chemical pesticides .Some of the advantages that nanopesticide formulations present are increased solubility of water-insoluble active ingredients, increased formulation stability, elimination of toxic organic solvents when compared to conventional pesticides, the ability to release active ingredients gradually, enhanced stability to prevent early degradation, increased mobility and higher pesticidal activity due to smaller particle size, and a larger surface area that may lengthen their shelf life . Furthermore, the nanopesticides we're interested in are synthesized using plant-based substances, making them promising alternatives to traditional pest control chemicals. Beans (Phaseolus vulgaris) play an important role in human nutrition due to their high nutritional value. However, phytopathogenic fungi, bacteria, viruses, harmful insect species and mites can limit and reduce their production. In the current paper, we present the framework on which plant based nanopesticide technology is based, as well as the various techniques for determining nanoparticle properties. We highlight the potential for several medicinal and aromatic plants from the Khenifra region in Morocco to be used in the synthesis of metal-based nanoparticles. We also reviewed the use of metal nanoparticles in crop protection, emphasizing the control of green bean’s pests and disease, while compiling numerous research that demonstrate their effectiveness. After comparing plant-based nanopesticides to chemical pesticides used to treat green beans in Morocco, it is clear that they have enormous potential for treating pests and diseases with fewer negative effects on the environment and human health.

<em>The main objective of the present study was to evaluate the physicochemical quality of raw cow milk produced in Fkih Ben Saleh, one of the major milk production areas in Beni Mellal-Khenifra region in Morocco located in the North-Centre of Morocco. Physicochemical quality of raw milk was determined by assessing the analysis of Fat Content “FC”, Protein Content “PC”, Total Solids “TS”, Solids No-Fat “SNF”, Acidity “Ac”, Brix “Bx”, Density “Ds”, Temperature “T°” and Alcohol Test “AT”, using recognized standardized methods and infrared methods for better assessing of characteristics (fat, protein, total solids and no-fat solids contents). The results obtained from this study showed an average ranging from 34.06 to 38.60 g/l, 30.01 to 31.61 g/l, 40.53 to 42.52 g/l, 116.03 to 121.51 g/l, 88.88 to 90.85 g/l, 9.87 to 10% for FC, PC, LC, TS, SNF and Bx, respectively. On the other hand, an average ranging from 14.62 to 15.04 D°, 6.68 to 6.76, 1.0208 to 1.0494, 0.517 to 0.532 was showed for Ac, pH, Ds and FP, respectively. Furthermore, all milk samples tested for AT were, in most cases, normal at different concentrations of 79, 76, 74 and 68% while T° of all samples collected from bulk milk was under 06 °C. The present findings showed a good quality of the milk produced in this area in terms of chemical and physical criteria. Finally, the milk originated from Fkih Ben Saleh could be considered as an important riche and source of fabrication of dairy products with high quality.</em><strong> </strong>

The aim of this work is to evaluate the antioxidant effects of the extracts of Pistacia atlantica collected in the Khenifra region (Morocco) in 2016. Different methods were used to study these extract: 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, the ferric reducing ability of plasma (FRAP) assay, the phosphomolybdate method for determining the total antioxidant capacity, and the electrochemical method for cyclic voltammetry were employed to evaluate the antioxidant capacity of Pistacia atlantica Desf. Phytochemical screening helped us to highlight the presence of secondary metabolites. The extraction of the phenolic compounds was carried out by the Soxhlet method in the presence of different mixtures solvents (ethanol/water and methanol/water); the fractions of the different extracts were affected using ethyl acetate and n-butanol. The dosage results showed that the ethanolic extract was rich in total phenols (260.4 mg GAE/g of the extract) and in total flavonoids (129.15 mg QE/g of the extract), while the butanolic fraction was rich in condensed tannin (50.96 mg CE/g of the extract). The qualitative analysis was performed by high performance liquid chromatography (HPLC). The main compounds that were identified in the methanolic and ethanolic extracts of Pistacia atlantica Desf were ascorbic acid, gallic acid, tannic acid, rutin, and quercetin. The results of the antioxidant activity revealed that the butanolic and ethyl acetate fractions exhibit a good iron reduction capacity (concentration that gave half maximal response, EC50 = 0.02 mg/ml and 0.03 mg/ml, respectively) and a very interesting antiradical activity with an IC50 (concentration of inhibitor where the response is reduced by half) = 0.08 mg/ml and 0.04 mg/ml, respectively. Cyclic voltammetry presented a single oxidation peak between 400 and 500 mV. The ethanolic and methanolic extracts were recorded from the oxidation currents values of 15.75 and 10.41 i/μA cm.2 respectively at the concentration 0.1 mg/ml. Hence, it is clear that the leaves of Pistacia atlantica Desf, which are currently often considered as potential antioxidants, contain antioxidants that can usefully be extracted and added to foods.

Dyslexia is the most common learning disability in school and the most devastating in terms of academic performance. In interaction with the socio-cultural environment, several and various factors can aggravate the difficulties of reader acquisition in dyslexic children. Identifying these factors and interpreting them according to the neuropsychological approach, in the Moroccan context, was the objective of this study Socio-economic data was collected from 626 children, aged 9 to 15 years with an average age of 11,95 years, enrolled in public educational establishments in the Beni Mellal-Khenifra region, located in central Mo- rocco. Among all the participants, 41 had a profile of dyslexia, 13 of whom had reading attitudes evoking "severe dyslexia". Subjects underwent a cognitive assessment. the others were normal-readers and classified as good readers (n=481) and weak readers (n=104). To follow our purpose, we have determined socio-cultural and cognitive variables that may discriminate between students in the "severely dyslexic" group and their "dyslexic" peers. The performance gap was significant in favor of "dyslexic" students in the reading test of pseudowords, rapid naming of images, and the deletion of the initial phoneme. These data reinforce the hypothesis that the phonological deficit is at the root of developmental dyslexia. On the socio-cultural domain, the results showed that preschool attendance and early exposure to written language activity discriminate the participants with a "severe dyslexia" profile from their peers in the "dyslexic" group. We believe that these two factors were responsible for the moderate intensity of the disorder observed in the "dyslexic" group. Our study also showed that bilingualism raises the degree of learning reading difficulties among students with this disorder. These results are consistent with those described in the literature, it suggests that dyslexics can implement compensation strategies both at the behavioral and neuronal level. They call on those in charge of the Moroccan education system to recognize the existence of learning disabilities of neurobiological origin in order to address the necessary care for children who suffer from them.

Full textAbstract:
The present research studies the geographical classification of olive mill wastewater (OMWW) samples using FT-MIR spectroscopy and chemometric recognition algorithms. The study focuses on samples collected from two regions in Morocco: BeniMellal-Khenifra and Fes-Meknes. Principal Component Analysis (PCA) has been applied to the spectral data, revealing distinct clustering of OMWW samples based on their geographical origin. Additionally, Partial Least Squares Discriminant Analysis (PLS-DA) has been employed to develop a classification model for accurate sample categorization. The PLS-DA model presented high sensitivity and specificity, achieving perfect classification rates during the calibration phase. Validation results show the model's capability to accurately identify the majority of samples, with a minor misclassification. These results confirm the potential of FTMIR spectroscopy and chemometric recognition algorithms for authentication, and traceability in the olive oil industry. Further research can explore the extension of this methodology to other regions and agricultural by-products, incorporating advanced machine learning algorithms for enhanced classification accuracy. Overall, the present study contributes to enhance environmental waste management research by addressing OMWW disposal concerns and promoting sustainable practices on the valuation possibilities.

Full textAbstract:
Over the last three decades, growing inequalities in countries have compounded the issues faced by society's most vulnerable populations. Students are facing the brunt of the effects in particular. A student's social vulnerability emerges as a result of the interaction of a variety of individual and environmental factors that accumulate over time. Poverty, material deprivation, and a lack of parental education can all have an impact on student assessment in school. Previous research has focused on the impact of psychological, cognitive, and physical functioning on children's education, ignoring students’ social vulnerability and its impact on educational achievements in developing countries. This paper aims to identify vulnerable regions that need attention and intervention by clustering Moroccan students based on their social vulnerability using an unsupervised competitive learning approach “Centroid neural network,” subsequently displaying the results in a choropleth map to visualize the results. For this purpose, we used the PISA dataset which contains the full set of responses from individual students focusing on specific information such as their parent’s backgrounds, socioeconomic position, and school conditions. Based on our current findings, we concluded that social vulnerability has a detrimental impact on students’ cognitive development. Moreover, the choropleth map shows that 'Beni Mellal-Khenifra' has the highest level of social vulnerability among all regions, besides "Marrakech-Safi" "Eddakhla-Oued Eddahab" and "Guelmim-Oued Noun" all of which have a high level of social vulnerability as well, urging academicians to incorporate resilience building into the design of policies in these regions in order to improve student’s educational outcomes.
