The development of information technology and communications consolidate a multimedia, multi-itinerary highway with new roads to manage knowledge, share best practices, and learn formally or informally, to acquire the competences required. University education in the twenty-first century is at the epicenter of this epistemological hurricane. As a part of this problem, the question arises

Simulation is a Greek word, was established by Aristotle in his book (The Art of Poetry) where he offered the principles of simulation by reaching that tragedy in action simulation and not only similarity in imitation that is why it entail selection, arrangement and events illustration that reveal the relationship between art and life? simulation finds that art is a direct mirror to life ?simulation theory illustrated in three trends simple simulation, core simulation and ideal simulation. On the other hand tendency formalism shows that exact art separates entirely from actions and themes that make up the usual experience. Art is a freestanding science that does not require repeating life as art. When the simulation theory moved to the Arab Monetary, it scrubbed and gained the status of Islamic realism that do not conflict with the principles of the mind and spirit longings but we find that tradition faddish life and follows it, that is why it includes period of time (occurred at certain time and ended) while decoration totally lack period of time and gained constancy character. While decoration knows nothing except stability and immortality. So simulation, non-simulation, ordinary, decoration, shaping and geometry are all considered Expression of two major patterns of human expression patterns linked very closely to the position of the artist and his community towards the environment he lives: the first pattern has the time period trait ( beginning & ending)that leads to meaning while the second illustrate stability and expansion that has constancy and immortality connected to intuition In general Arab Islamic art falls within the non-simulation arts acquired from the influence of Islam decisive basic characteristics, a characteristic which had a far-reaching aesthetic charm on the reviewers from within the Islamic world and beyond Which made the Arabic language subject to the requirements of the new reform and though spread throughout Asia and eradicated the old dialects and ruled out. Artist Ebadi Hafez has said "I try to keep the core values of the letters which leads me to art by its role, united spirit of the Arabic script with the movement in art the spirit of the Arabic letter is united with the progress in art " that is why we noticed that most of his work with Arabic letter is documented on walls in Paris and Europe. He assures that his use to the calligraphy in Europe countries is relations establishment between east and west that required the presence of bilateral awareness of the importance to build a coherent world. From here our research problem is raised for the need of the letter element in clarifying the fundamentals of fine arts that assure its value and concepts.

Plagued by coups and political crisis that gradually destroyed the state apparatus, central african republic comes out from a humanitariam and security crisis marked by a political and religious context. The international community had to get involved to restore peace. The last elections won by Touadera open a new era. Reconstruction seems to be vital. Our concern is to know how these new elections may contribute to national reconstruction. Challenges are enormous : restoration of the rule of law by ensuring respect of the constitution, restoration of state autority throughout the national territory in addition to the reform of security forces by instructing and equipping them, promoting peaceful coexistence and inter-sectorian in equality and ethnic geopolitical balance. This reflection is not only spot to mark the way for national reconstruction but also to restore the state sovereign powers. The government, the country

In this study, we have established the relationship between the seasons and the rate of flow of the Congo river during two periods of observations, the first from 1990 to 1999 and the second period from 2000 to 2009. It was observed a pluviometrical increase form the first period to the second. This fact should be correlated to the climate change characterized by the dry and wet seasons associated with low water and flood periods, respectively. This climate change has a real impact on temperature which is increasing.

The impacts of climate change of Osse-Ossiomo River Basin in the South-West of Nigeria under different climatic Scenarios were investigated using information on rainfall - temperature for forty years (1961 - 2000). Discharge information of Osse and Ossiomo rivers was collected for the period from 1989 to 1994. A number of water resources development schemes including hydroelectric and water supply projects have been planned in the southwestern of the river system of Nigeria. Results revealed fluctuating rainfall pattern with great uncertainties in the mid-1980s. Temperature shows an increasing trend and the highest temperature of 37oC was obtained in 1998 during the 40-year period. There is a strong evidence of global warming using the index of temperature in the drainage basin. River discharge also indicated fluctuating trends from year to year in the decades with records. It was concluded that the river discharge pattern of Osse-Ossiomo River Basin exhibited similar behaviors as other drainage basins of the world. Climate change has impacted on the river discharge of Osse-Ossiomo. This has implication on water security, sanitation and health of the inhabitants in the river basin. Most people were forced to resort to various sources for the numerous uses of water. Statistical tests had shown that the changes in rainfall temperature and rainfall discharge were significant at the 5% level.

Chilli, or Capsicum annum, is a high value cash crop. Cultivation of chilli had been done using the conventional method and fertigation system. There are two methods of fertigation system practiced in Malaysia, which are planting chilli under rain shelters and open fertigation and planting chilli without rain shelter. All three planting systems have their own advantages and disadvantages. This study was conducted to evaluate the costs and benefits of chilli cultivation using both the fertigation system and conventional methods. Data were obtained from the pilot project plot under MARDI and the Department of Agriculture. The cost-benefit analysis showed that the costs of production for chilli using both fertigation systems were RM1.19/kg (under the rain shelter) and RM1.56/kg (open fertigation), respectively, compared to RM2.03/kg using the conventional method. The net income per season per hectare for planting chilli using the fertigation system under rain shelter was RM105,654 and open fertigation was RM77,415, which were higher than the conventional method (RM55,900). The higher net income was due to the high yield of chilli, almost twofold per hectare, than the conventional method. The partial budget analysis also showed a higher benefit value than the implication value in the event of farmers switching from using conventional methods to chilli cultivation using both fertigation systems. Overall, chilli cultivation using fertigation technology is proven to improve chilli yield and has a high viability. The high cost or initial capital will be offset by the high production yield. This technology is also more environmentally friendly than the conventional methods and in accordance with the practice of sustainable agriculture development, besides conforming to the present national agriculture agenda.

The development of fungi in stored grains present a health risk to customers due to their ability to produce and accumulate mycotoxins. Then, chemical antifungal agents are applied to grains to reduce their contamination by molds. The aim of the present study was to evaluate the antifungal potency of oregano essential oil and thymol on some species of fungi involved in corn spoilage. Molds were isolated, and then identified by their macroscopic and microscopic characteristics after cultivation on standard media. The antifungal activity of oregano essential oil and tymol was conducted by broth dilution method. The mold species isolated were Aspergillus niger, Aspergillus flavus, Penicillium sp., Fusarium sp., and Mucor sp. Oregano essential oil and thymol demonstrate an antifungal effect against all these isolates. These compounds may be useful as alternative in limiting or preventing the development of harmful fungi and mycotoxins in food.

The quality of higher education institutions and students is significantly an impact toward the development of their country. A partnership between an educational institution and industry is a step that is often used by the developed countries in America and Europe. A major success factor in institution-industry partnership is the willingness and ability to collaborate in teaching quality. A unique partnership is implemented in the remote area, Indonesia that is undertaken by Polytechnic, Indonesia through practice teaching in the industry. The basis of this partnership is the lack of the practice facility that owned the educational institution so that the industry provided solutions to use existing industrial facilities to support learning practices for Polytechnic students. A team of Polytechnic partnership should responsible to plan, to implement, and to evaluate through an implementation guideline that approved by industry. Industry requires that polytechnics prepare basic knowledge and competence of their students before they follow activities of teaching and learning in the industry. This paper is to discuss partnership program implementation carried out between polytechnics and industry in the remote area, a model of sustainable partnerships of the teaching program between polytechnics and local industry, and benefits of a partnership program between polytechnics and local industry. These are conducted to create graduates, according to labor market needs. The partnership program is also more optimal if it supported by a good communication between Polytechnic, industry, and government.

Local authorities play a key role in managing local affairs and territorial governance in all its administrative, financial dimensions... So it is noticed a strengthening in recent years of the process of decentralization and advanced regionalization by allowing the local elected the means and instruments to enable them to improve significantly their managements. Therefore, and in the current context that is marked by the strengthening of the policy of decentralization and significant transfer of responsibilities to local authorities, they are constantly faced to the improvement of their performance in order to establish a new, more transparent and effective governance which is facing some shortcomings. It is for this reason that we find new ways and management tools such as the use of audit on local authorities in order to appreciate the different aspects of the functioning of local governments and to ensure their regularity, efficiency and performance at all levels. This is why the current new organic law of local authorities focus on the external audit due to its critical role in the implementation of principles of good governance in local authorities.

Nowadays, commercial enterprises confront a clientele increasingly informed and therefore demanding and volatile, especially in the telecoms sector in Morocco. For that purpose, the customer capital becomes a central concern of these companies. Furthermore, the solution that seems most effective to deal with these challenges is to set up a relational dimension. In order to verify the impact of the relational dimension of marketing on customer loyalty, an empirical study was conducted with 138 customers of Moroccan telecom operators (Maroc Telecom, Meditel and Wana Corporate). The results of this study confirm that all elements of relational marketing have a positive and significant effect statistically on customer loyalty. Found and develop a customer capital is the aim of any business. To this end, Moroccan telecom operators must establish trust with customers, to notify their customers of any information deemed useful and satisfy their expectations while being close to the customer as well as personalizing the customer-company relationship.

Introduction: Since more than two decades, the territory of Masisi in North-Kivu province is dived in a crisis whose contours are far to be known. The objective of this study was to assess knowledge, attitudes and practices of the population of Kamuronza grouping concerning management of conflicts and peace promotion in view to contribute to the funding of the peace in North Kivu province. Methods: In November 2015, a descriptive study has been conducted close to 448 people inhabitants the seven localities of Kamuronza grouping nearby from a questionnaire and focus groups. Results: Of land conflicts, identity, socio-economic, bound to rapes and sexual violence and based on the gender and those related to the abuse of the power and the exploitation and the natural resource depredation have been identified. Knowledge of the population of the grouping of Kamuronza concerning management of conflicts and peace promotion were insufficient. A negative attitude persistence within the population has been observed as well as a good practice insufficiency concerning management of conflicts and peace promotion. Conclusion: The population directly concerned by these conflicts is to place to the center of the solution research while privileging the backing of his community capacities concerning management of conflicts and peace promotion and the social dialogue that will permit him to understand reasons of conflict and their dynamics better, and, will give him means to formulate some concerted actions in favor of the peace.

This work is to study the influence of form deviation on the tolerance analysis of a mechanism. In this case we use the worst case method. We also use the deviation domain. The study is primarily to assess the accumulated tolerances while assuming insignificant form deviations and secondly to integrate these deviations to assess the functional condition which is defined by orientation tolerance.

Recruitment as one of the principal practices of the human resource management represents a major stake in all the organizations and in particular in the multinational firm. However the risk to fall into discrimination is current there. This work seeks to study this phenomenon with the help of a qualitative study conducted near ten Tunisian subsidiaries of Multinational Firm. At the conclusion of this research, discrimination with recruitment seems to exist in all the subsidiaries, but to differing degrees. To avoid it, we propose criteria of equity like the adaptability, the good knowledge of the profile, the good definition of the station and the equal opportunity.

Gnetum africanum Welw belonging to the botanical family of Gnetaceae (order Gnetales ) is a wild plant of Central African forests. It provides a non-timber forest product called "koko" harvested for its food and commercial interest. In Congo intensified harvest caused its disappearance around major cities and the remoteness of rural harvesting sites. The objective of this study was to know the influence of light on the potential and spread of different growth stages in relation to the change in canopy gaps that allow the entry of light into the undergrowth. The study was carried out in the departments of plateaux and Kouilou where two and three sites were sampled respectively. The analysis of forest sites by basal area led to distinguish the forest regrowth, the young secondary forest and old secondary forest or mature. Recruits are characterized by large canopy gaps ranged between 50.5

The fermentation process of Sorghum wort is one of the fundamental steps that determine the quality of tchapalo (traditional beer). Its assessment through biochemical parameters such as pH, temperature, total soluble solids (substrate), biomass, released carbon dioxide and alcohol (ethanol) content allowed capitalizing values during the experiments. Analysis of the evolution of these biochemical parameters showed significant variations (P < 0.05) during the batch fermentation process of sorghum wort. Thus, the biomass reached a maximum average of 27.64 (

In the search of strategy for an effective use of impregnated mosquito nets by the populations, the impact of active distribution on the use rate of long lasting impregnated mosquito nets (LLIN) and on the transmission of malaria was studied in rural areas in the South of Ivory Coast, in 4 villages of Bassam and Adzop

The characterization of the fungal flora of the breeding litter Achatina fulica and different incubation substrates (coconut husks, cotton wool, sawdust, planting soil, virgin forest soil) of the eggs revealed the presence cosmopolitan fungi such as Aspergillus Niger, Fusarium oxysporum, Fusarium solani, Mucor sp., Penicillium decumbens, Penicillium sp. and Trichoderma sp. Note however that fusaria are only present on the breeding litter the giant African snail. The percentage of occurrence of fungi varies from one substrate to another. Aspergillus Niger remains the only fungus present on all substrates and Penicillium decumbens only on the planting soil. Similarly, the characterization of the potential of each of toxigenic strains performed through the identification technique by HPLC was able to detect and quantify ochratoxin A and aflatoxin G2, G1, B1 at most samples (eggs + fungus ) except that consisting of eggs + Fusarium solani or no mycotoxins were detected. Ochratoxin A detected in samples containing Aspergillus Niger, Oxysporum Fusarium, Mucor sp. and Penicillium sp. is present in very small quantities in the set. The aflatoxin B2 is absent in all samples.

This work was carried out at the Field Crop Institute-Agricultural Experimental Station of Setif (Algeria) during the 2008/2009 cropping season. The objective was to evaluate some pheno-morpho-physiological and agronomic traits in five durum wheat (Triticum durum Desf.) varieties and F2 segregating lines. The results indicate the presence of a good amount of variability for the measured traits. Low relationships between wheat productivity and the physiological traits is found, which makes them less effective as selection criteria in the case of this study. However, the above-ground biomass measured at maturity stage seems to be the determinant factor in grain yield expression. High heritability associated with high coefficients of phenotypic and genotypic variation values, along with high genetic gain are recorded for the above-ground biomass and spikes weight per plant, suggesting that early selection based on these traits would be effective to improve the stress tolerance and enhance the productivity of the F2 studied populations.

The excessive use of antibiotics has become a global problem our day in light of the emergence of multidrug resistance of bacteria strain. The search for the discovery of new antibiotic is not moving as fast as that. It is with this that we undertook this study. We have developed the health regulator BIOFOR as an alternative to antibiotics for face care that does not require the use of antibiotics. Our study shows that the BIOFOR health regulator stimulates the immune system. There was a significant increase in both leukocyte and lymphocyte count compared to normal. The prophylaxis plan BIOFOR has allowed growth very significantly higher compared to conventional chicken prophylaxis plan. The relative organ weight was allowed to show that organs are well developed. Thus the measurements of AST and ALT enzymes have allowed showing that the BIOFOR prophylaxis has no hepatic, muscle and heart toxicity. The BIOFOR health regulator is a purely natural product made from plants. The results of our work allow saying that the use of the BIOFOR health regulator would be beneficial to human health in order to avoid the systematic use of antibiotics.

Epidemiological monitoring integrating spatial and temporal dimension, geographical information systems (GIS) appear as a management tool, planning tool, and Support Tool Decision of sanitary policies. This study aims to map cholera sanitary risk in order to improve its monitoring due to better fight against the disease in Abidjan. The combination, of multi-sources data (QUICKBIRD satellite image, socio-environmental survey results and epidemiological data) in a GIS was used to analyze the sanitary environment in precarious settlements and the spatial pattern of confirmed cases of cholera over the period 2011-2012. This analysis was done using environmental and socioeconomic characteristics that influence vulnerability to cholera and to categorize households according their vulnerability indexes. Analysis of the results shows that all households are vulnerable to cholera with a high index ranging between 2.5 and 3.5 on a scale from 0 to 5. Boribana and Divo have respective indexes 3.07 and 3.05 followed by Mossikro and Zimbabwe each with 2.94 and 2.92. Bromakot

The liquid waste refining station of the International Market of ARKEZE, which has three lagoon basins with microphytes, faces important development problems. Those problems include the low production of liquid waste, the plugging of the main water pipe - which usually results in olfactory nuisances, the frequent breaking of the pipes that drain the liquid waste to the station, the lack of maintenance of the station - which causes a high rate of mud in the anaerobic basin. This investigation aims at studding the hydraulic functioning and assessing the different basins. To that purpose, quality indication measures have been carried out for ten weeks on samples, some of which have been taken daily and others weekly. The liquid waste

The effect of stocking density on the growth performance of Clarias jaensis in pond was studied in the zone of Nkolnkondi II, area of center Cameroon with an aim of contributing to the improvement of the production by the optimization of the stocking densities.

The main objective of this article was the assessment of the impact of damage caused to the MIOMBO clear forest on the diversity of litter fauna. In order to lead to results it was specially selected three different stations (the MIOMBO clear forest, the shrub savannah and the farmed field) those were characterized by the pH, the water content and the organic matter concentration of their soil. The litter fauna species listed on the inventory of the Miombo forest were compared in quality and quantity to those listed in shrub savannah and the land under farming after the calculation of diversity indications. So it was brought out that the acidity and the organic matter concentration were more considerable in the soil of the forest than the shrub savannah and the land under farming. The same goes for the litter fauna that was more abundant and diversified in the forest (to wit the relative abundance of 59, 8%) than the land under farming that has registered 30, 4% of all listed species and the shrub savannah with 9, 8% only. These results constitute the evidence that damages caused to the MIOMBO clear forest has negative actions on the abundance and diversity of the litter fauna.

The Niayes area is an agricultural region where market gardeners use a lot of fertilizers and pesticides. With irrigation, water infiltration can lead with it chemicals that can reach the groundwater that is used for drinking by the population and other domestics activities. The study presented in this paper is to assess the risk of contamination of the groundwater consecutive to the use of chemicals in the Niayes area. To perform this, we used the HYDRUS-1D software to model and visualize the spread of flow concentration of the constituent considered as pollutant from the soil surface to the water table. For pollutants we considered in our simulations, urea and NPK 46% mainly used in the Niayes area. The amounts of fertilizer considered in the simulations are those recommended by the Regional Agriculture Center of Thi

The environmental education and health is one of the major axes of the Moroccan school curriculum, giving us the opportunity to assess the interlinkages between knowledge and behaviors taught students about the environment and health in schools. From an analysis of the curricula of Life Sciences and Earth qualifying secondary school , and a study via a questionnaire for secondary pupils qualifying , it was noted the existence of attitudes to health risks and behaviors that do not respect the environment.

This study was conducted to evaluate the morphological and agronomic performance of ten varieties of sweet potato grown in Bongor in Chad during the dry season. The average length of internodes of the main stem and means the collar diameters were measured and maximum growth rates associates were determined, the length and diameter of tuber were measured, the number of tuber per plant were recorded tuber yield, the diameter/length ratio of the tuber, the average weight of tuber and dry matter aboveground biomass were determined. The results, it appears that varieties BF 59 and BF 40 have the longest and varieties BF 108 and TIB have diameters in the larger collar internodes. The highest growth rates were noted between the 37th and 51st JAP and between the 23rd and 72nd JAP respectively for the length of internodes and the collar diameter. For agronomic parameters, variety BF 108 was more effective for most of the studied parameters. This variety seems interesting for the selection of work.

At the end of the red waste biotransformation an alga Gelidium agar -agar sesquipedale after extraction, we achieved a finished product free of pathogenic bacteria and rich in protein 26%, fat 0.40%, carbohydrate 38% and 11% minerals. Three diets containing respectively 20%, 25%, 30% seaweed waste are compared with a commercial ration to determine the best growth on sheep. We followed the weight gain and average daily gain during the 90 days. Four batches of ten sheep each were submitted to the fattening test. Lot 1 receiving the food (F1) reached an average gain resulting weight of 14.5 kg or average daily gain (ADG) of 161 g / d. Lot 2 receiving the food F2 recorded an average weight gain of 16.3 kg is the equivalent of a daily gain 181 g / d. As for lot3 nourished by the food F3, marked the largest average weight gain of 19.35 Kg, a daily gain of 215 g / d. The control group regarding showed him a mean weight gain of interest near that of lot1 13.3 Kg, which corresponds to an average daily gain of 147 g / d. In addition, microbiological analyzes of sheep carcasses and viscera showed that total mesophilic anaerobic flora varies between 102 and 103 cfu / g and faecal coliforms vary between 1 and 3 cfu / g. Salmonella and clostridia are totally absent. These results confirm the possibility of solving problems due to protein and mineral deficiencies in animals by adding these fermented waste and obtain a clean and healthy meat for consumption.

Intimate Partner Violence is any behavior within an intimate relationship that causes physical, psychological, or sexual harm to those in the relationship. The study was carried out in Babati district in Manyara region where 94 respondents were involved. The cross sectional research design was adopted due to the nature of the study and the data were obtained from focus group discussions, key informant interviews, questionnaire and documentary reviews. The study aimed at exploring the major causes of intimate partners

The observation of the coast on the level of Vridi Ako lets appear several old barriers of beach. Four (4) wells were dug on one of these barriers of beach in order to know its lithology and the grain size of sediments. Moreover, a mineralogical and morphoscopy analysis of sands was made. The lithology is characterized by an alternation of layers of color yellowish gray and olive gray with the appearance of a surface of white color. These layers consist of sands whose average of sizes varies between 0.470 and 1.269 mm. these are essentially of coarse sands, good enough classified at very well classified. The mode (Mo) indicates that the shape of the graph is bimodal. This shows that there are two sources suppliers of sediments (hinterland and continental shelf). There is also the following mineral: the sphene, the rutile, the anastase, tourmaline, and unspecified minerals. The quartz grains are primarily very round to sub-angulous with as a whole a shining blunted aspect.

In the context of the global change, the loss of biodiversity in the forests-savannas mosaic zone of West Africa constitutes a growing problem. The sale of cashew nuts remains one of the main economic resources of C

In physics, the circular motion is described by more than one method, any of them can be used to drive the same equations that govern the behavior of the body in its circular path. Due to these equations, satellites are placed in their orbits, the curvilinear paths are designed with more security such that, cars or trains continue in motion with their high velocities. In the other hand, all these methods failed to describe how the motion of the body is controlled. In addition, they also failed to give reasons why some quantities disappear as if, they are destroyed or balanced. In this research we show that, to describe any motion, the accuracy of the description will be close to the exact one if we use most of the physical quantities that affect the body to control it path. A cording to this method we use the moving body's forces , the side reactions of the body, the centripetal force and the body's momentum to describe the circular motion . As a result we see that, our method can answer most of the questions that the other methods failed to give, and corrects all the mistakes that are considered as scientific evident in the other methods.

Epileptic power supply by the service provider has been a major bottleneck in the bid of residential building occupants to use their electrical appliances indoor for comfort drive. Thus, this study is aimed at investigating and analysing usage of generating sets by the building occupants in Ibadan Metropolis, Nigeria. Data were collected by administering questionnaires on the respondents. The 59 political wards in the 5 local government areas of Ibadan Metropolis were stratified into core, transition and suburban residential zones. Twenty five (25) per cent of the wards indicating 15 wards were selected across the three zones. By using systematic sampling technique, 2% of the residential buildings totaling 736 buildings were sampled across the zones. The study revealed that the average duration of power supply that was incidental to dependence on generating sets in residential buildings in the core, transition and suburban zone was 4.37, 5.31 and 7.63hrs respectively. Also, 45.82% of the respondents had used their generating sets for 3 years; 93.78% largely depended on petrol engine generators; and 71.43% of the respondents could not use their generating sets to power all their electrical appliances at a moment when compared with the normal voltage of power from the service provider (IBEDC). The study concluded that the type of generating used depended on the socio-economic characteristics of the respondents and recommended that government should ensure sincere deregulation of power sector and seek for more environmentally energy sources.
