Many studies were carried out in Morocco to show that the dynamics of the market gardening is characterized by frequent use and often uncontrolled use of chemical inputs to the detriment of the preservation of natural resources, the health of consumers and the producers themselves. This reality, calls for appropriate structural actions, based on the levels of sustainability of the sector. The IDEA method (Farm Sustainability Indicators) is one way of giving practical expression to the concept of sustainable farms. Based on 40 sustainability indicators covering the three dimensions of sustainability: agro-ecological, socio- territorial, and economic. Using the IDEA method, we conducted this research with a view to analyze the sustainability of market gardening exploitations in three rural communities: Mnasra, Sidi Mohamed Benmansour, and Benmansour. We conducted questionnaire interviews with 180 producers. The results obtained have generally shown that the market gardening farms in this region have low sustainability scores. The sustainability of farms is lowest on the socio-territorial scale due to the absence of product quality approaches, poor human development, and poor employment conditions and services. On the economic scale, the low viability stands out. The agro-ecological scale shows higher values due to the good organization of space and diversified systems.
The objective of this article is to study the existing relationship between training and the integration of Sustainable Development (SD) practices in the Moroccan University. The issue at stake is to verify whether the training provided at the level of higher education institutions responds to the various worldwide challenges. In order to respond to the difficulties that impact the higher education model, Moroccan universities are invited to rethink their various approaches so that they can respond to the economic, social, societal and environmental constraints which are constantly evolving. Therefore, these universities must align themselves with the major challenges facing education today[1]. The empirical research method used in this quantitative study is a Likert’s scale based questionnaire. The investigation was carried out on a sample of 134 teachers-researchers of Ibn Tofail University of Kénitra (ITUK) (Morocco). The investigated sample population was surveyed during the time period lasting from February the 1st to May the 31th, 2021. The analysis conducted regarding the results of the ANOVA of the variables reveals that the pedagogical approaches, curriculum and teaching methods are significant except for the teaching activities which display a value of 0.280 higher than the recommended threshold. Consequently, training in higher education can contribute to forging attitudes in the future in line with SD’s requirements by relying on pedagogical approaches. Hence, the University through training should contribute to a sustainable society in order to meet the 17 SD Goals which require that by 2030 all students should have the knowledge, skills and attitudes necessary to promote sustainable development. The results of this research will contribute to the development of new training curricula that meet the requirements of the various SD objectives. We have focused our research on the ITU Kénitra, we believe that our approach will serve as a basis to develop other cases of Moroccan universities to have an overall vision of training curricula converging towards the practices of SD at the Moroccan national level and for a better contribution in the new 2035 nationwide development model[2].
Introduction: The current study aimed to explore the in vitro antioxidant, anti-inflammatory, antidiabetic, and dermatoprotective properties of lemon peel essential oil (EO). Methods: The chemical composition of lemon EOs extracted from the lemon of three cities in Morocco was investigated using gas chromatography-mass spectrometry (GC-MS) analysis. The antioxidant property was estimated by two complementary tests: Ferric ion reducing antioxidant power (FRAP) and 1,1-diphenyl-2-picrylhydrazyl (DPPH). The in vitro anti-inflammatory activity was assessed by the inhibition of albumin denaturation and proteinase. Inhibitory properties of α-glucosidase and α-amylase were used to reveal the antidiabetic activity of lemon peel EOs. Dermatoprotective property was evaluated by the tyrosinase inhibition method. Results: In addition to high amounts of polyphenols and flavonoids, GC-MS analysis of lemon peel EOs demonstrated the presence of D-limonene, β–pinene, and γ-terpinene as the main compounds in the three samples studied. Lemon peel EOs exhibited significant antioxidant activities by IC50 values ranging from 40.57 µg/mL to 100.22 µg/mL and 113.63 µg/mL to 180.90 µg/mL obtained by DPPH and FRAP tests, respectively. in vitro inhibition of enzymes involved in inflammatory response revealed that lemon peel EOs presented remarkable inhibitory activities against albumin denaturation (230.48 µg/mL>IC50<341.13 µg/mL) and proteinase (199.70 µg/mL>IC50<307.05 µg/mL). Moreover, lemon peel EOs demonstrated powerful inhibition of α-amylase and α-glucosidase with various IC50 values (1689.06 µg/ mL>IC50>4000 µg/mL and 1021.58 µg/mL>C50<2467.62 µg/mL), respectively. These EOs also revealed significant inhibition of tyrosinase with IC50 values ranging from 248.42 μg/ mL to 378.02 μg/mL. Conclusion: These results revealed that lemon peel EOs might constitute a new product with beneficial biological abilities against the mentioned complications.
The main objective of this work is to determine the effect of the harvest period on the yield and chemical quality of the essential oils of the Eucalyptus sideroxylon A. Cunn. leaves of the Mamora forest, Dayet Zerzour Bnifdel region, Rabat. Essential oil yields are remarkably high above 2.3%, with an ultimate rate of 5.48% for the month of April. The chemical quality of these essential oils is characterized by the presence of two major monoterpenes, 1,8-cineole (eucalyptol) and α-terpineol, which are proportionally inverted in terms of quantity. During the wet months between September and March, the cineole predominates with levels ranging from 72.67% to 86.11% and the other dry months are characterized by an increase of α-terpineol rate from 12.05% to 25.61%. This inverted chemical variability reveals a change in the orientation of cineole and α-terpineol biosynthesis under the control of climatic factors. This work allows us to discern favorable periods for the harvest of Eucalyptus sideroxylon leaves in terms of yield and quality of essential oils.
The present work aimed to determine the difference in the chemical composition of essential oils isolated from two parts of Cupressus arizonica and to evaluate their in vitro antimicrobial and antioxidant effects. The yields of the essential oil obtained by hydrodistillation from the leaves and cones were 0.85% and 1.29%, respectively. The chemical analysis of the constituents of the two essential oils of Cupressus arizonica was carried out by using the GC and GC/MS techniques. The results of this analysis show that the leaves are dominated by cis-muurola-4 (14), 5-diene (21.27%), umbellulone (19.88%), α-pinene (9.39%), and α-muurolene (7.87%7); on the other hand, the cones are rich in α-pinene (51.07%) accompanied by other variable content constituents, myrcene (17.92%), limonene (9.66%), β-pinene (4.92%), meta-cymenene (2.6%), and α-terpineol (2.38%). The antimicrobial activity against four bacterial strains, four wood decay fungi, and three mould strains were determined using the agar-agar dispersion method. The studied essential oils exhibited moderate antimicrobial properties, which demonstrates the sensibility of all strains tested with the exception of wood rot fungi to which they do not have activity against all concentrations tested. The dosage of antioxidant activity was evaluated using DPPH scavenging and ferric ion reducing power (FRAP). The results indicate that the essential oils from cones of Cupressus arizonica possess a strong antioxidant activity (lower IC50) IC50 = 0.098 ± 0.008/EC50 = 0.646 ± 0.02) in comparison with those from the leaves (IC50 = 5.297 ± 0.09/EC50 = 2.335 ± 0.36). The results suggest that both essential oils could be used as a source of treatment for bacterial infections and also as natural antioxidant substances.
Customer satisfaction is the key to success in all organizations and this satisfaction has a correlational relationship with the quality so that is why we notice that during the last ten years, the automotive sector focuses on the quality whose new strategy reinforces to develop quality and anchors Morocco in the global automotive industry. This article describes the use of Six Sigma through the DMAIC method (Define, Measure, Analyze, Improve and Control) during production lines in a wiring company. The objective is to reduce the defect rate to improve the quality of the product. After defining the workplace and measuring the defect rate, a structured analysis was done to find the root causes and then actions were implemented to reduce the defect rate. To this effect, the deployment of this method has reduces the rate of defects. The use of the Six Sigma method plays a key role in improving the quality of the product as well as financial gains for the different companies.
