The present study aims to analyze the hydropluviometric variability and the dynamic of land cover in the catchment of the Sota located at the North-east of Benin. It is based on the exploitation, on one hand, of rainfall and runoff data over the period 1965-2010 and, on the other hand, of satellite images Landsat TM of 1995 and Landsat 8 OLI/TIRS of 2013. The calculation of rainfall and hydrometric index and the application of statistical tests were used to analyze the hydropluviometric variability in the catchment of Sota. This variability is marked by similar fluctuations of rainfall and runoff. The break identified on rainfall and hydrometric series in 1970 is followed by a rainfall deficit of 6,76 % and a flow deficit of 33,75 %. The analysis of land cover maps produced from satellite images made it possible to release the land cover dynamic. This dynamic is characterized by the regression of natural vegetation formations to the profit of anthropic formations. The crops areas and fallows knew the greatest expansion with an annual growth rate of 6, 16 %. The degradation of the vegetation cover is undoubtedly one of the factors of the persistence of the relatively high level of the hydrometric deficit in the watershed of Sota.

The processing of sugar cane in Morocco is by specific industrial units. The SURAC Company (Dar Gueddari) produces significant quantities of sugar and molasses in a period of production that extends the month from January to June Wastewater produced by this activity is characterized by very high loads of organic matter whose flow is 1200 m3 / d. The stock SURAC its wastewater Lagoons with limited capacity for pretreatment in wastewater. The aim of our study was to assess the pollution of waste water from the SURAC at the lagoon which is adopted by the SURAC as a means of treating these liquid discharges. The physicochemical analysis of effluent from the SURAC gave the following average values: PH (Moy=4,15), Temperature (Moy= 25
The developed crucible furnace has the capacity to melts 30 kg of Al-Si alloy scraps in 20 minutes during which 7 litres of spent engine oil was used up at a flow rate of 5.833 x 10-6 m3/sec. The overall thermal efficiency of the developed crucible furnace was 46.74% on its performace evaluation. Its operating cost is cheaper since, spent engine oil is relatively available and the incessant increment in the price of fossil fuel will no longer have effects on the production costs. The performance of the equipment is better than the traditional ways of non-ferrous metals recycling exercise and its adequate implants for conversion of waste engine oil and Al-Si alloy scraps to wealth.
In recent years, many designs have been developed for the anaerobic treatment of leachate. The UASB (Upflow Anaerobic Sludge Blanket) is currently the most recent process used for the treatment of these discharges in Morocco, it is a treatment system known by low sludge production and a high methanogenic activity. This work aims is to present the importance of leachate treatment of household waste from the town of Kasba Tadla in Morocco By a process of UASB. Our team is interested in studying how management and recovery of household waste in the city of Kasba Tadla in Morocco. We have shown on one hand the evolution of the tonnage of household waste in the period between 2014 and 2016, as the importance of screening and also determine the evolution of the quantities of leachate produced daily basis for four months, of January to the month of April 2015 and the characteristics of these liquid discharges and their impact on the environment and thought processing techniques. The results obtained in this study show that the production of household and similar waste of around 11849 tonnes in the year 2014, and 0.27 tonnes / capita / year. These wastes are essentially of the organic material (74%), paper (3%), plastics (9%) of metal (1%) and glass (0.5%). The quantities of leachate produced monthly at the city range from a maximum of a maximum average daily volume of 2320 liters per day during the month of April 2015, and a minimum average daily volume of 1028 liters per day during the month January 2015 with a monthly average of about 46,656 liters per month. The physicochemical analysis of leachate from the region shows a high concentration of organic matter, COD is about 12240 mg O2 / l and high acidity (pH = 5.16), hence the importance of treatment these effluents through effective and adaptable technology to weather the study area namely the UASB technology before the direct discharge into the environment. Leachate treatment by the UASB technology has allowed us to have an allowance of 93% of COD and pH shift to neutral (pH = 6.9). In conclusion, the results show the success of the leachate treatment UASB technique in the study area, especially that this technique is already proposed by the urban municipality for the treatment of wastewater.
This study examined the behavioral intention to implement sustainable waste management on primary school students by using the framework of the Theory of Planned Behavior. The purpose of this study was to determine the factors associated with the behavioral intention to implement sustainable waste management. Population and sample in this study were primary school students in city of Padang, West Sumatera, Indonesia. The data collected for this study were analyzed using structural equation modeling. The results of this study stated that the knowledge of the sustainable waste management has a significant relationship with the attitudes towards the sustainable waste management behavior. Attitudes towards the sustainable waste management behavior, subjective norms, and perceived behavioral control also had a significant relationship with the behavioral intention to implement sustainable waste management. This study has helped in understanding the relative strength of the determinants of the behavioral intention to implement sustainable waste management. The biggest strength is the relationship between the perceived behavioral control and the behavioral intention, followed by the relationship between subjective norm and the behavioral intention, and the weakest were the relationship between attitude and the behavioral intention. These findings have important implications for the school as well as for policy makers.
Moringa oleifera from India in the valleys south of the Himalayas, is a tree species with multiple virtues, now present in tropical and subtropical areas. The present study focuses on the endogenous knowledge and importance of Moringa oleifera in eight departments (Atlantic Coastline Ou
Problems related to the elasticity, studied based on the models represented by the elliptic equations are characterized by their invariable in time. For an isotropic compressible medium, the loss of ellipticity criterion depends on the determinant of the Hessian matrix of the energy potential and therefore invariant tensor Cauchy Green. Necessary and sufficient conditions on the ellipticity or Legendre -Hadamard condition are given from two energy functions of polynomial type from the isotropic compressible case.
The Study aimed at learning the effects of the suggested photography program on developing creative abilities in third grade female students at the Intermediate level, within the city of Jeddah. The Quasi Experimental approach was used; it was based on two groups; Experimental Group and Control Group. The sample included (42) forty-two female students from intermediate third grade in the city of Jeddah. It comprised instruments of the suggested photography program for three weeks. Additionally, the researcher used creative thinking tests in the Aurora Battery. The research results were as follows: There was a difference of statistical significance at the level of (0.05) between the average of the Experimental and Control Groups in the overall creative abilities. and in each component of its sub-components (i.e. quantitative, formal, verbal) which was in favor of the Experimental Group. Upon these findings, the researcher was able to reach the following recommendations to pay attention to the Intermediate Level Curricula in general, which includes mechanisms that would help students to develop creative thinking skills and to use a camera during the courses' applications.
The present study aimed to investigate the effect of different plant growth regulator namely 2,4 dichlorophenoxy acetic acid (2,4-D) and ?-Naphthalene Acetic Acid (NAA) on callus induction of Helianthus annuus L. Callus culture were initiated from three explants namely cotyledon leaf, hypocotyl and root segments explants of in vitro Helianthus annuus L seedling. Both auxins 2,4-D and NAA stimulate callus induction, however 1.5 mg/L 2,4-D proved to be more effected for induction of callus. Among all treatment media containing 1.5 mg/l 2,4 D showed highest response of callus degree (3.44
In a bit to contribute to the study of the sedimentary Formation of the Mungo series, studies on the Mungo river Formation was effectuated in this work. The reconstitution of the paleoenvironment in which the formation was put to place has been done based on six analyses: granulometrical, morphoscopic, heavy mineral, thin section analyses, as well as mineralogical and chemical analyses by x ray diffractometry and fluorescence respectively. From the granulometrical analyses, plurimodal histograms are indications of multiple sources of sediments. The granulometrical curve show low gradient. The sediments are therefore very poorly to poorly sorted.The morphoscopical analyses reveals the presence of: quartz grains that has not been worn out (53%), having been eroded from proximal source rocks (short transport); sub spherical and shiny quartz grains (44%) having been subjected to an averagely long transportation; spherical and shiny quartz grains (3%) having been subjected to relatively long transportation. The heavy mineral analyses reveal a variety of heavy minerals: pyroxene, rutile, tourmaline, zircon, are indications that part of the sediments came from magmatic source rocks; also, the presence of andalousites is indicative of a metamorphic source rock. The examination of thin sections reveals that the rocks are essentially lithic arkose and litharenites which are respectively less consolidated and averagely consolidated. The x ray diffractometry on a clay facies reveals that it is made up mostly of clay sized particles rather than clay minerals (i.e made up mostly of quartz and hematite with koalinite being the only constitutive clay mineral). A chemical analysis by x ray fluorescence has unraveled the major and trace element contents of the clay facies. The paleoenvironmental context in which the terrigenous detritic facies of the Mungo river Formation was put to place could have been fluvio-deltaic to shallow marine. At a larger scale, the paleoenvironment of deposition of the Mungo series could have been fluviatic to fluvio-deltaic and shallow marine.
Map satellite lineaments served as study support for gold geochemical sampling of Lolodorf region in the southern part of the Eburnean Ngovayang massif in Cameroon. This technique is a major step in the search for clues metal geological and mineral exploration fractured zones. 228 samples were analyzed and the levels vary from 301ppb to -2ppb. These results showed that the probability of greater than 10ppb levels, which may lead to a gold anomaly is 67.48% for areas where the concentration areas weaving lineaments are superimposed on high density areas lineaments, 2.31% for the concentration of intersection surfaces lineaments, 28.92% for areas located in the high density areas levels of lineaments and only 1.28% for areas located in isolated lineaments. This study confirms the hypothesis that the areas of intersections and high density of lineaments are directly related to high concentrations of geochemical elements and mineral deposits.
The aim of this paper is to study the relationship between rural poverty and local governance while emphasizing the importance of the link between agriculture and industry. Our empirical study focuses on the case of Tunisia over a period ranging from 1990 to 2010. The estimation results show that a reduction of rural poverty is achieved by improving local governance and a complementary relationship between agriculture and industry.
Beyond a diagnosis that would only reason out the shortcomings of the practice of human resource management within the company and the causes of this situation, the issue of this thesis aims to identify the various factors and elements that do not favor a true and complete implementation of a human resources management policy in a Moroccan company and their degree of implementation on the company's performance. Thus, the study focused on the impact of human resource management on a company performance. For a better rapprochement of the theoretical research to those practices, we examined a quantitative vision of practices HR in the company to discuss later the degree of implementation of HR practices on the performance of the company. We highlighted our research with a company "Source Marrakech" specialized in the bottling of water that is based on the establishment of a HRM policy to achieve business performance. This communication is not, moreover for its essential, that is the outcome of experience within the company (combined certainly to my theoretical research), proposes to treat the above problem by posing a plan for treating indicators of key measures of HR poles (employment, compensation, appraisal of staff, training, management of jobs and skills and the development of human resources) and their influence on the company's performance via while proposing a research model to affirm or deny.
The purpose of this study was to describe, evaluate, and identify psychoactive substances and its risk factors among Moroccan drivers. The epidemiological and cross-sectional survey concerned 428 drivers: heavy weight (70) Coach (67) Automotive (234) and taxi (57). The support of the survey is an individual questionnaire comprising four sections: individual characteristics of drivers, medical practices, toxicological habits and knowledge of road safety. The results show that drivers constitute a population at risk : Medical Habits: risk taking drugs and driving (61%), followed by chronic treatment (37.9%), medication without prescription (55%), non-compliance of the treatment rest before driving (70%) , toxicological habits (tobacco : 53.6 % alcohol : 27.17%, illegal drugs : 18.97%, tea : 31.1%, coffee :15.4%. Their knowledge of road safety is very poor: ignorance of the Highway Code and the risk factor in the decision of psychoactive substances are respectively about 73% and 80.6 %. Prevention and reduction of accidents related to the taking of psychoactive substances pass through awareness and training of drivers on the real risk of this factor.
Most of water resources nowadays are exposed to pollution caused by domestic, industrial and agricultural wastewater. Pollution is also caused by climate changes, acidic rain, etc. The superficial pollution can infiltrate through soil into the underground water. The danger of this pollution depends on the nature, concentration and type of the pollutants. The main objective of this study is to evaluate and control the physicochemical quality of underground water of ALLAL TAZI- Gharb Morocco .The research is carried out on 22 underground water wells in the region under study. It analyses and controls 12 physicochemical parameters of the collected samples in ORMVAG Laboratory, Kenitra. These parameters are pH, EC, Ca2+, Mg2+, Na+, K+, Cl-, SO42-, (NH4+) et NO3-, CO32- et bicarbonate HCO3-.The results have shown that the concentration of ammonium NH4+ in 95% of wells and nitrate NO3- in 68.2 % of wells are much higher than the World Health Organization (WHO) norms . This indicates that there is nitrogen pollution as a result of industrial and domestic organic waste or due to the excessive use of soil fertilizers. The electric conductivity in 31.8 % of wells, concentration of chloride Cl- in 41% of wells, and concentration of sodium Na+ in 31.8% of wells are relatively higher than WHO norms. This explains the existence of high level of mineralization in water-wells of the region under study as a result of geological structure or industrial and domestic pollution. The study has also revealed that other parameters are approximately in concord with the norms set out by WHO. It is concluded that the physicochemical quality of the underground water of the region under study is medium.
The elderly passes through many physical and physiological changes which necessarily reflected on the psychological and social features in him. The psychological status in the elderly is a result of a number of factors, each one of them affect positively or negatively on the psyche of the elderly. It is therefore not a typical case of all people, but each one of them has his own case according to the influence of different factors and the extent of his influence. These psychological changes at this stage necessarily require aesthetic formulation of the surrounding environment in order to achieve psychological comfort and calm. And from this came the research idea of preparing the elderly surrounding environment through designing printed fabrics for furnishing the rooms to suit this stage taste and give the sense of psychological comfort and calm on the elderly. The researcher did this through displaying opinion poll on a sample of elderly people (male and female) to know the preferred color groups to the elderly which raised the feelings of each color group. The recent studies proved that color considered as one of the important design elements. It affects the human when he sees it because of the reflected colors .It gives the elderly the sense of tranquility and comfort or sadness and depression. It has been recording their color preferences and use them in designing suitable designs for every type of textiles (Curtain- furnishing) by using sample geometrical shapes which inspired from some paintings of modern art. So this study considered as an attempt to compensate for the decline in the mental status resulting from the decline in the physical condition of the elderly and his inability to movement as in the past. Therefore he/she would have to stay at home for long periods and especially in the bedrooms or living rooms, through changing the surrounding environment of the elderly through creating designs suitable for print upholstery fabrics for the elderly rooms according to their preferences of color that rise the positive senses in them.
The present study was undertaken with the objective of comparing the structure, the richness and the floristic diversity of the forest settlements of zones with Pericopsis elata (clay soil) and those with Julbernardia seretii (sandy ground) in the Uma plain forest located in the Ubundu Territory, District of Tshopo in Orientale province of the Democratic Republic of the Congo (DRC). This comparative study is a contribution to the improvement of knowledge on the influence of the ground type on the species distribution in the forest of low altitude of Uma. To carry it out, we inventoried all the trees having dbh?10 cm (all species) on 24 plots of 0.25 ha (either, 6 ha on the whole: 3 ha per zone). The following results were obtained: (i) A total of 2372 trees (for all the species) were listed: 1340 (467 trees/ha) for the settlements with Pericopsis elata and 1032 (344 trees/ha) for the settlements with Julbernardia seretii. They respectively represent a basal area of 29 m
Companies tend increasingly to turn to the improvement steps in order to boost their performance and thus enhance their competitiveness. In times of crisis, the use of such steps is no longer a choice, but is an obligation. In this context, Lean Six Sigma is uncontested today a vector of business development through various objective tools, and also by the involvement of various company stakeholders. In Africa, the Lean Six Sigma seems like an opportunity to seize and operate. Is it then a management instrument submitted to the fad after the massive craze, or he is a real performance improvement tool for African business and thus responding to a actual need? This article aims to shed light on the reality of the practice of Lean Six Sigma by African companies through the assessment of lessons learned in the field, culminating in the end a synthesis on issues and deployment prospects of this approach in the context of sustainable development.
Soil characteristics and metals contents are important components for playground safety, but these are lacking in third world countries. In the present study thirty six soils samples from nine preselected public schools playgrounds were characterized using standards methods. Results revealed poorly equipped and maintained playgrounds with pH < 7 for all playground soils indicating acidic soils while organic matter ranged from Ikenegbu primary school (0.2 %) to World Bank Primary school (2.8%), sodium adsorption ratio ranged from Model Nursery school (0.41 (Cmolkg-1)05) to Shell camp primary (0.77 (Cmolkg-1)05). Other physicochemical characteristics had values comparable to those of typical acid sand derived soils whose textural class is sandy loam. Electrical conductivity varied widely amongst playgrounds ranging from Housing Estate primary school (3.2 S/cm) to Shell Camp Primary school (9.5 S/cm) indicating presence of some soluble inorganic salts. These soils characteristics therefore constitute major favorable conditions for the release of toxic metals in the soil or runoffs.
Theories are organizing principles by which thought processes are clearly set out in such a way that enable various studies to explain issues relating to them explicitly. Over the years, linguists have provided theories that have been used to capture some aspects of language descriptions and analysis. This is owing to the fact that no single theory has been found to capture all of the aspects of language(s) explicitly all of the time. Practitioners of theories have taken them to heights that even the original exponents have never thought of. One of these theories is the theory of Standard Language, the subject matter of this paper. This paper sets out to examine the origin of the theory of standard language, its principles and application on new idioms and idiomatic expressions in Yoru?ba? with a view to establishing its analytical strength and appropriateness.
