Mobile commerce is especially attractive to Chinese college students since it offers the possibility of purchasing goods and services from anywhere at any time. Electronic commerce has produced increasing revenues since 1990. M-commerce represents a newer source of revenue with great potential as part of e-commerce. This research proposes to determine significant factors influencing the intention to adopt a new m-commerce application by a group of college students in Nanjing, China, using a formative Structural Equation Model. The model uses a set of 11 indicators to build the final construct. Results from this study identified the following factors as significantly influencing the intention to adopt a new m-commerce application by a group of college students in China: Perceived security, Perceived Ease of Use, Perceived Enjoyment and Perceived Compatibility. These results have some partial similarity with previous research. However, Perceived Compatibility appears as the single factor not common with previous results indicating an increased interest from Chinese college students to have an m-commerce application that is compatible with all their mobile devices. Significant factors identified in the present research according to the value of the coefficient of determination R2 have substantial explanatory power. Explanatory power of the model presented in this research improves those from previous studies. However, further studies are needed with larger sample sizes to corroborate the results presented in this research.

Floods are one of the most common natural disasters causing many casualties and significant economic damage around the world. Hurricane Florence and Typhoon Mangkhut in 2018 were only the last reminder of the disruption caused by the catastrophic floods. Despite significant safeguards to reduce fluvial flooding risk, further efforts are still needed. This study is part of the NABRAPOL (NEBARSKA POLYMER) project, which aims to improve the knowledge of the drag reduction effect on free surface flows, a new protection technique used to reduce the rivers flooding risk. This article presents a state of the art in terms of fluvial flow modeling in the presence of polymers to strengthen flood risk management. A modeling approach for flows mixed with polymers is described. A case study on the watercourse modeling containing a flow without and with polymers is presented. The modelling results show that the addition of polymers to the flows watercourse results in a marked drag reduction by decreasing the water depth up to 18% of its initial depth. This technique can be considered as an efficient new method for strengthening non-structural protection measures against river floods risk.

Gabon contains the richest and most diverse forest block in the Congo Basin. More than 50 non-timber forest products are listed. Despite this natural advantage, Gabon continues to import many forest products, including spices. The present work was initiated to study some morphometric, physicochemical and biochemical characteristics of a species of local wild pepper (Piper guineense), in order to domesticate and commercialize it. The results obtained showed that the leaves of this pepper had average leaf area of 106.71 cm2. These organs contained 87.57% moisture content, 17.13% dry matter and 3.4% crude ash. At the biochemical level, the wild pepper leaves of Gabon contain 26.04 g/ 100 g of protein DM, 21.48 g/ 100 g of total sugar DM and 244 g/ 100 g of chlorophyll Pigment FM. This plant is also rich in polyphenols (0.6 g/ 100 g DM) and ascorbic acid (3.58 g/ 100 g DM). It is not very pungent and contains only one (1) digital unit of Scoville. All these physicochemical and biochemical characteristics bring this morphotype closer to other types of pepper imported from Central America or Asia. Gabon's wild pepper can therefore be domesticated and marketed to reduce the country's food dependency.

The experience of pregnancy, accompanied by physical and emotional changes, will have an impact on the couple's sexuality. The purpose of this study is to focus on the issue of sexuality during pregnancy, to look at its variations and describe the different changes in sexual parameters. In our study about 170 cases, 91.76% continue to have sexual intercourse during pregnancy, 7.6% thought it could be responsible for miscarriages, infection or bleeding in 26% and 20% respectively. The main reason for the continuation of the sexual intercourse was looking for husband’s pleasure and the preparation and facilitation of delivery. In contrast, female pleasure was expressed in only 4% of women, discomfort at the time of the sexual act dominated the reasons for which sex was stopped or spaced. There has been a gradual downward trend in most sexual parameters: frequency of sexual intercourse, sexual desire, sexual satisfaction, and frequency of orgasm.

This is a 28-year-old woman nulligeste, followed for hypothyroidism under levothyrox consults for a primary infertility of 1 year. She did an infertility checkup: an ultrasound examination that showed a myomatous uterus and ovaries seat of a dermoid cyst. In hysterosalpingography, she has opacified tubes up to their isthmic portion without peritoneal diffusion. The husband's investigation is normal. She had a diagnostic laparoscopy that showed bilateral tubal agenesis with a negative methylene blue test. The patient is proposed for in vitro fertilization.

The sale of bananas on the markets of the commune of Ibanda town of Bukavu is one of sectors of creation of abstract jobs in favour of the disadvantaged social groups, left for account, among the population of this city, namely the stripped women, the unemployed young people, the not provided education for girls, etc. This activity deserves to be modernized, structured, to be organized and supported by the organizations as well public as private so that it becomes really a true fish pond of employment to the profit of honest of this urban and rural population that it employs. Provincial and central government urban development policies should be geared towards solving material (insufficient commercial infrastructure, commercial facilities), fiscal and financial constraints (excessive taxation on small banana sellers and resellers, insufficient capital, difficult access to credit for small sellers and small retailers), commercial, economic, administrative and social constraints, which small sellers and sellers of dessert bananas, sweet bananas and plantains working in this commune face on a daily basis. This research reveals that three main units of measurement are present in the markets: main bananas, a banana, and the banana diet, but they are not standardized. Among them, the hand is the most applied unit in all markets. They are the abstract markets, decentralized markets, markets of streets which know a great passion of the applicants and record the greatest quantities of sale of bananas. The soft bananas and plantains are bought in commune of Ibanda compared to bananas serves. The quantities sold by the women would be almost the same ones as those sold by the men. The factors of limitation of the performance of the die banana in commune of Ibanda are: the abusive tax on the small salesmen and soft banana retailers, plantains and serves, the dubious and insufficient customers, the insufficiency of the fixed places in the markets and strategic sites of the city to contain all the salesmen, the bulk-heading of the markets and sites of sale, the means of transport used by the small banana retailers.

The reversal of the situation of supply of the town of Bukavu with food and non-food products in favor of local products, is a matter which obliges the emergence of the policies of incentives and facilitation of the marketing of agricultural products. It is no secret that in South Kivu, the agro-pastoral sector no longer produces products capable of meeting the demand of an ever-growing population in the city of Bukavu. It is also observed that very often the prices received by agricultural producers hardly encourage them to increase agricultural production. On the other hand, sellers and resellers, as well as consumers in the city of Bukavu are turned to outside products. Suddenly, mistrust of products from the territories of South Kivu increases as a result of the qualitative and quantitative mediocrity which does not favor their commercial promotion. The supply of the city of Bukavu with food and non-food products from the territories of the province of South Kivu faces the following main difficulties: the advanced deterioration of transport infrastructure, the lack of transport equipment, costs and high transport costs compared to products purchased abroad (in Rwanda, Uganda, Burundi, etc.) for 26.6% of respondents; commercial, social, administrative and fiscal harassment in the rural and Bukavu markets, the indifference of services and public authorities to the problems of marketing local agricultural products, for 21.6% of respondents, and the instability of supplies in the territories, the unavailability of various lots of desired products, the poor quality of certain local products, the strong competition from outside products (from North Kivu, Rwanda, Uganda, Burundi, etc.) for 25% of respondents. The constantly growing demand of the city of Bukavu for food products must play a driving role for the increase of agricultural production at the provincial level, provided that the supply circuits in the various sectors are organized in a rational manner. It would take a synergy effort for the supply of Bukavu with food and non-food products from the territories of South Kivu to be profitable, resilient and sustainable.

The main objective of this study is to make profitable the exploitation of fresh cocoa in the sector of Nganda Tsundi, Tshela Territory, Kongo Central Province, in the Democratic Republic of Congo, in order to improve the well-being of its population. The documentary review on cocoa cultivation, the survey of 69 cocoa farmers and the breakdown of data; have formed the methodological approach begun. The results showed that: 91.8% of income is over-spent by village planters for harvest because of the lack of specific tasks for this operation, compared to SCAM's production standards for the same crop, or to harvest pods to produce 111,666 Kg of beans, 20,040,000 FC are spent in the village instead of 1,642,000 FC at the SCAM. The planters pay the labour to pick up the pods at harvest while the SCAM assimilates this operation to the harvest. So for milled beans equivalent to 111.666 Kg the planters lose 3.480.000FC against zero costs to the SCAM. As for the total cost of production, the production of 111,666 kg of fresh beans results in 52.16% of expenditures by the cocoa farmers of Phalanga Ndenga, whereas it would only result in 7.68% of expenditures at the SCAM. Make this profitable exploitation among the farmers of Phalanga Ndenga, contributed to the reduction of the anthropic pressure of the forest ecosystems of this sector.

The Psychological Contract is an important emerging area of human resource researchers and practitioners. Increasing recognition of the importance of human resources in enhancing Organizational performance, coupled with wider concerns about reputation and competitions have made the issue of Psychological Contract of highly relevant to researchers and those managing Organizations. Hence, the objective of the study is to analyse the effects of the psychological contract factors operationalized in terms of transactional, rational and employee performance in a private sector organisation in Cameroon. A structured questionnaire adapted and validated for this study was used to ascertain the responses of the respondents. A self-administered questionnaire was used to collect the data from twenty-five (25) samples. The analysis was conducted using SPSS, the major findings of the study indicated that Transactional Psychological contract has a strong positive significant relationship with turnover intention of employee in private organisation Also, the Relational were significantly related to employee performance in the said private organisation there by implying that a beach in the psychological contract has a significant effect on the performance of employee in an organisation. The owner/managers, regulatory agencies, government and other stakeholders will benefit from the findings, and recommendations suggested.

This study examined the Determinant of Intangible Asset Disclosure of Banking Sector in Nigeria. A sample of (15) selected banks was used for the period of 2009 to 2018. The study was predicated on Ex-post facto and longitudinal research design and used secondary data for the analysis. The data collected were analyzed using descriptive statistics, Correlation Matrix and Ordinary Least Square regression. The result revealed that there is a significant and negative relationship between bank size and Intangible Asset Disclosure which was statistically significant at 5% level of significant while a positive and significant relationship was documented against Bank Age and Intangible Asset Disclosure which was statistically significant at 1% level of significance. The finding shows that 68.7% of the system variation in Intangible Asset Disclosure was jointly explained by all the independent variables of our sampled banks over the 10 years period while about 31.3% of the total variations were unaccounted for, hence captured by the stochastic error term. The study therefore recommends among others that decrease in banks size should be encouraged since it enhances intangible Assets Disclosure among Banks in Nigeria while existence of old generation banks should be encouraged as it helps in compliance with disclosure policy.

Currently, learning foreign languages remains a crucial issue today. The idealis to power less Several languages at once. It's all that many parents want for children. That said, learning the foreign language has gained importance over the years. It allows the student to choose new horizons, but also to acquire new skills taught. Besides that, knowing another language allows to discover a country in another form. It is possible, for example, to see the cultural language of a particular country. In addition, innovation in language teaching is a challenge for faculty. It consists in following the new strategies of the acceleration of the pace of learning, the reinforcement of the desire to learn, the encouragement of intellectual curiosity as well as the creative initiative of the learner. It is therefore a question of making the lessons of an exchange course free, of creating conversations and simulation games in order to make the class a useful and pleasant moment where the student becomes the real actor. Why then learn foreign languages in this case the French, Arabic and Amazigh languages? That is the question we are going to solve.

In order to better circumscribe a petroleum field, several delineation drilling must be carried out to obtain the maximum of the data by using various methods and techniques which will lead to modeling the reservoir to optimize the recovery of its hydrocarbons. Thus, during the drilling of the OKA-01 oil well in the Tshiala (Offshore) field of the DRC coastal basin, the Pinda formation presents an extreme lithological complexity with a combination of siliciclastic carbonate which is associated with a wide variety of environments. We used a method called Gas While Drilling that uses surface-detected gas during drilling for fast determination of valuable reservoir information such as identification and characterization of hydrocarbons in the lower Pinda reservoir, which are the subject and the contribution of this study. The obtained results from this study are represented in graphic form or figures and cross-plots; the latter are analyzed and interpreted according to the different components present in the fluids, that is to say the quantity of the components (C2-C5) to that of the component C1 as well as the rations of Wetness Ratio (Wh); Balance Ratio (Bh) and Character Ratio (Ch). Data collected from our method compared to other methods used during this drilling of the OKA-1 well identified and characterized the heavy oils in the OKA-01 well, indicating a problem of their recovery with primary methods. and secondary; allowing to consider tertiary recovery techniques with a work over project.

The disruption of global macroeconomic balances has had consequences both at the state and individual levels. In several countries and in the Democratic Republic of Congo in particular, the population is plunged into extreme poverty. In the current post-conflict context in the DR Congo, we observe a multiplication of local initiatives enabling the populations to face current problems (poverty, the accentuation of inequalities, the satisfaction of basic needs, unemployment, low income, growth, social cohesion, famine) and to provide for basic and urgent needs. The overall objective of this work was to analyze the contribution of the associative movement in the development of the Shabunda territory. A survey questionnaire was developed with the aim of triangulating the different information, this study found it useful to randomly survey different socio-economic levels. The result on the factors which influence the proliferation shows that 40% of the interviewees affirm that the problems of the community occupy the first rank for the explanatory factors of the proliferation of associations, another group of surveys is 31% confirming that the presence of Organizations Non-Governmental is also at the base of this proliferation of these associations because these structures finance the actions carried out by these associations. The associations manage to carry out the actions on the ground, starting with local participation with a percentage of 38% and secondly with animation or awareness raising with a percentage of 36%, so that the population becomes aware of their community problems, which problems resolved by local participation. Significant change is observed in the area of food security at 23% activities are more devoted to this sector, A change in mentality is observed at 20%, and access to work at 22%. Most associations operate in the agro-pastoral sector (44%). On the other hand, 16% of associations intervene in the resolution of conflicts.

Introduction: Intestinal parasitosis are neglected diseases that are still a major public health problem in tropical countries. Objective: This study was undertaken to evaluate the impact of seasons in a subtropical climate on the occurrence of intestinal parasites in children under 5 years of age. Patients and method: The study concerned 504 cases of children under 5 who consulted at the "Afia-Sake" Reference Health Center and carried out direct parasitological examination of stools. Each patient underwent a fresh optical microscopic stool examination by the direct physiological saline technique and positive results were reported for the different subtropical climatic seasons corresponding to the date of each child's passage to the Health Center. Result: The prevalence of intestinal parasitosis is 94%, the most affected age group is between 18-29 months with a predominance of female. We did not find a statistically significant difference between the presence of parasites and the seasons; for, the risk of having mono-parasitoses during the long rainy season and the risk of having poly-parasitoses during the short dry season appeared equal. conclusion: Periodic chemoprophylaxis with deworming, drinking water supply without health risks, hygiene and sanitation and veterinary public health measures should help to curb these endemics.

Innovation is becoming more and more a success factor for companies worldwide and Morocco has adopted a national policy that encourages innovation and research and development in recent years. Our job is to make a diagnosis of the current state of business innovation challenges in Morocco. In this article we analysed the current situation of innovation in the Moroccan industrial sector. For this, we carried out a survey of forty companies in the industrial field in Morocco, based on a questionnaire that we have developed in our research laboratory. The interpretation and analysis of the results obtained are summarized, on the one hand, by the structural incompatibility of companies with the means required for innovation, and on the other hand by the problem posed by the technical level of the players and employees of companies to make possible the design and production of innovative products. We have dealt with issues related to innovation in Morocco from two different angles: firstly, the direct or indirect barriers or obstacles to the integration of innovation, and secondly, internal and external levers. That can encourage manufacturers to adopt innovative solutions.

Technical progress and innovation must play a very important role in protecting the environment by meeting the needs of present generations without compromising the ability of future generations. The challenges of the environment are universal: the daily erosion of biodiversity, the generation of waste and the consumption of excess energy, have all become the concerns of all industrial and academic actors. Studies show that the majority of waste thrown into the wild is no longer collected for possible recycling and negatively influences biodiversity. This research article proposes two innovations to reduce the impact on the environment of two products used frequently in everyday life: the whiteboard marker and the toothbrush, which generate a lot of indirect waste during their production and waste. direct in nature after their end of life. Our innovation is the design of an "eco-marker" and an "eco-brush" that are not all disposable in whole. Both solutions are to keep the body of the marker for a very long time, and to keep the handle of the toothbrush and just change the head: which will significantly reduce the generation of waste.

This article focuses on the study of the link between human resources management (HRM) practices related to continuous training and the three-dimensional organizational involvement of employees of private companies in Morocco. The research results show, on the one hand, that continuous training is a lever of affective organizational involvement and, on the other hand, an absence of correlation with normative involvement and calculated involvement.

The clandestine exploitation of gold in Nyan in the Adzopé department with its rapid evolution has led to an uncontrolled migration of miners. This article aims to determine the impact of clandestine gold mining on Nyan populations. It also aims to highlight the interactions of the actors in the controversial resilience game system of illegal gold panning in the village of Nyan. Adopting a qualitative approach for data collection, individual interviews and focus-groups were used. The results show that this clandestine activity has contributed to the creation of other income-generating activities and to improve somewhat the living conditions of some villagers. Beyond these advantages, gold panning in Nyan has negative impacts on the environment, health and daily life of the people. Awareness campaigns among the various social strata of the village and sometimes intimidations presented themselves as an alternative of resilience which helped to put an end to this activity in the village.

After several decades of economic expansion, the growth process continues to put negative pressure on the environment and the quality of life. Combining poverty and social precariousness, the economic model has not been able to meet the growing needs of humanity because of the limited nature of natural resources. Societies cannot continue to consume this way, it is imperative to reduce the negative impact on the environment. More than that, we have to look for a way to get back within the limits of the planet's resources. In this context, green growth is an opportunity to put economic activity back on a path that is more respectful of the environment. This growth represents for Morocco an opportunity so that its economy opts for a path of sustainable development. The objective of the article is to discuss how to combine optimality and durability of growth to achieve a model of humanistic and sustainable development for Morocco. We show that this requires a number of tools that allow this transition.

Since its independence, Morocco engaged in the process of decentralization which results in the creation of the public administrations of proximity called territorial collectivity, this orientation rested with the new constitution in 2011 the adoption of the organic law. From this point of view and with resulting from the various dysfunctions it was imperative to adopt a new public management that is based on action and places the satisfaction of the citizen at the center of concern.

This study is about research works which have as objective to assess the present state of preschool education in Morocco in general and in Meknes in particular. It was carried out through face-to-face interviews with the various officials at the Meknes-Tafilalet regional academy of education and training as well as in in the Meknes provincial direction. It allowed us This enabled us to investigate official documents and analyze the state of preschool education and curricula. A questionnaire was also administered to a representative sample of preschool educators at the level of 67 institutions. Research has revealed that preschool offer in Morocco remains limited and unsatisfactory in terms of quality as well as quantity, in spite of the adoption of the urgent programme (2009-2012) which aimed to generalize quality preschool education again. Almost all preschool establishments are private (Kouttab and modern establishments) and unequally distributed through all the municipalities. Many of them do not comply with the specifications produced by the competent educational authorities. Too much diversity in curricula and lack of training of educators only detract from the quality of this type of education. All these points correspond to obstacles and challenges that the Moroccan government must overcome in order to develop and improve preschool education in the Moroccan territory.

This study was conducted in Republic of Benin to compare the effectiveness of two forms (powder and extract leaves) of Spondias mombin on the milk production of the Djallonke ewes as well as weight gains of theirs lambs. The experimental part involved 18 lactating ewes divided into three homogeneous groups of 6 animals each that received orally and separately powder and extract of leaves of Spondias mombin. The results of experimental study showed that powder of leaves of S. Mombin improved significantly the milk production of ewes (707.94 ± 24.34 VS 650.30 ± 26.37 and 647.18 ± 50.77) and weight gain of lambs (ADG: 112.67 g/day VS 90.67g/day and 89.47g/day). The extract of leaves of S. Mombin had less effect on milk production or on the growth of lambs compared to the powder group, but had more effect compared to the control group. Treatments based on S. Mombin had no effect on the variation of body weight of ewes during lactation (p>0.05). Also, the leaves of Spondias mombin had no significant effect on ph, dry matter content, ash content, protein and milk fat (p > 0.05). The powder of S. Mombin can be a best source of plant drug to increase the milk production on african livestock for malnutrition reduction.

The construction of hydraulic structures on watercourses modifies the flow conditions and the extent of flood propagation zones. To do this, the installation of the structures must be preceded by models ensuring the correct dimensioning of the structures and their influence on the hydrological functioning of the watercourse. This study used hydrometric data, satellite images and cartographic data to design a run-of-river dam and model its influence on the propagation of floods from the Davo River to the drinking water production station in Gueyo (Côte d'Ivoire). The dimensioning of the weir gave the following main characteristics: 2.5 m heigth, 1.3 m wide at the crest, 3.8 m right-of-way and 177 m long. The retention created by the presence of this weir answer the population's water needs, which are estimated at 0.19 m3/s, or 16,800 m3/day. Simulation of the behaviour of the Davo River during high water periods shows that the presence of the weir does not have a significant impact on the extent of the floodplain area.

This study aims to show how do the Value at Risk contributes at measuring the risks that face the financial portfolio and its damages using a Financial Portfolio that was formed from five normal stocks of listed companies in the Kuwaiti financial market of 2018. The study has adopted confidence levels of 99%, 95% and 90% to calculate the value at risk using historical simulations and comparing it to the parametric method to the daily portfolio returns. The study resulted at there are some differences between the two methods, and that this qualitative tool is accurate and important in estimating maximum losses that can be achieved within the selected time horizon of one day and a month.

In its 2016 report, the Economic and Social Council of the State of Morocco notes, in a social framework that since 2007, a clear improvement in the average standard of living of Moroccans with a reduction of the monetary poverty rate. Such an effort was only possible thanks to, among other things, the National Initiative for Human Development (INDH) based on a participatory approach. An approach that repositioned Income Generating Activity (RGA) at the center of the production process in the social and solidarity economy as a lever for economic and human development. And in order to achieve the objectives of the INDH, these activities have proved to be effective in helping the disadvantaged to integrate economic circuits and improve their social condition. This paper examines the impact and importance of IGAs in the face of constraints such as illiteracy and lack of a culture of entrepreneurship. In order to answer this problem, we will analyze the impact of the AGR projects on the socio-economic situation of the beneficiaries in the prefecture of Inezgane-Ait-Melloul through a field survey conducted with about forty people. The main result of this study shows that these igas have a positive impact on the socio-economic life of the beneficiaries.

Women empowerment is an important issue of socioeconomic development of a country. However, in Benin where the situation of women remains worrying, the question of empowerment is very little tackled by research. Accordingly, this paper analyses the empowerment of rural women in the central part of Benin. Based on a random sample of 190 rural women and using empowerment indices, the study shows that only 19% of the women enjoy a decision-making autonomy whereas 41% of them are free of mobility. About the leadership, the most of the women can neither integrate nor leading any rural organisation without the consent of their husband, although they clearly enjoy a financial autonomy. The results also show that there is a significant relationship between decision-making autonomy and freedom of mobility. In the same way, decision-making autonomy is correlated with the marital status of women. Due to the influence of social norms and customs on the current situation of the women in the study area, one can suppose that any boosting of the empowerment process is subject to a major change in these factors.

This work focuses on the avian biodiversity inventory of the city of Bunia. The bird specimens were obtained by the Capture-Marking-Recapture (CMR) method using the Japanese net trapping technique. A total of 5 nets (3 m wide, 8.5 m long and 35 mm mesh) were used and observations with the naked eye completed the sampling. Fieldwork was done every Sunday; the nets were installed online. They remained in place for eight hours and the readings were made every 2 hours between 08:00 and 16:00. This study leads to a census of 53 species of birds. Spatially, 29 species are constant and 24 accessories. The Shalom University concession (S2) has a high specific richness (45 species), followed by the Pan-African Higher Institute of Community Sciences (S4) and the Grand Seminary (S1) (22 species each). Temporarily, 30 species are constant and 23 accessories. The first rainy season offers a high specific percentage (34.5%), followed by the second rainy season (27.4%) and the first dry season has a low percentage (15%). The Shalom University concession has a high number of individuals caught and species recaptured. The same concession (S2) offers a high number of individuals (349 out of 756) observed. The first rainy season also offers a high number of individuals (349) observed, followed by the second rainy season (127 individuals).

Remote sensing is an indirect tool for prospecting the Earth's surface. It is very powerful especially in its applications related to the field of geology. This work is part of the use of remote sensing as a tool to direct prospectors to areas that may contain mineral concentrations, saving both time and cost. We will limit ourselves mainly to the study of a Landsat 8 satellite image captured on 22 July 2016 around the Precambrian inlier of Bou-Azzer-El Graara, Anti Atlas Central region in Morocco and another Landsat 7 image. The latter did not give good results considering the problem at the level of the image sensor unlike that of the Landsat 8; the Optimum Index Factor (OIF) calculation makes it possible to detect that the most important colored components are, in the order of priority, 567 (with the OIF = 8830), 467 (with the OIF = 8446), 456 (with OIF = 8387) and 367 (with OIF = 8063); The reports of the bands, rations, and the Principal component analysis PCA, made it possible to carry out a cartography lithological and hydrothermal alteration as well as maps of lineaments by means of the directional filters; the assembly and the interpretation of these information plans allow us to know the zones with mining potential. The validity of the models is tested by comparison with field data and geological maps of the studied site.

In Morocco, vicia faba is considered the most important legume for both food and feed. However, the ravages caused by pathogens remain hardly controlled. The objective of the present study is to evaluate the efficacy of Urtica dioica and Capsicum frutescens’ extracts in protecting broad beans against Bruchus rufimanus infestation. To this end, the research was conducted at the National Institute for Agricultural Research in Meknes (INRA) during the 2015-2016 crop years. The experimentation was conducted in pots with four replicates to evaluate the efficacy of aqueous extracts of urtica dioica and capsicum frutescens on five varieties of Vicia faba beans. The cultures were spread with the aqueous extract of these two plants from the beginning of flowering to maturity. The results of the study showed that the aqueous extract of c. frustescens at 100g/l dose, decreased the rate of infestation of beans by bruchids by 16.35% while for the other treatments, no decrease was recorded. In addition, an increase in yield was notified for the aqueous extract of u. dioica at the dose of 100g / l with a percentage of 4.96% and a pourcentage of 8.18% at the dose of 200g/l.

This paper presents the numerical method used to solve the nonlinear plasma fluid equations. We have developed a fluid plasma model for a microwave plasma CVD reactor used for diamond thin film deposition. This model solves the electron and ion continuity equations, momentum transport equation and the Poisson's equation. In these equations we have the problem of non-linearity which is solved using the Newton’s method. From these equations, the unknowns computed are electron and ion densities (ne,ni), and plasma potential (ψ). Then the impacts of the hydrogen pressure and microwave power density have been studied. Simulation results show a strong effect of these parameters on the species densities distribution in the plasma.
