In the Gambia, particularly in the Lower River Region, agricultural production in mt has increased over the past two decades despite variability in rainfall conditions. In response to this finding, the study aims to analyze the evolution of rice and maize production in the Lower River Region, and to determine, in particular, the dependence or independence of each production on rainfall and cultivated areas. To do this, data on production in mt and hectare cultivated areas of rice and maize between 1981-2016, and precipitation data over the same period are used. These data are derived respectively at the level of the Gambia Department of Agriculture Planning Services and the Department of Water Resources. Their treatment was based on statistical data, including descriptive statistics, Pearson correlation, and simple linear regression. The calculation of the simple linear regression at the p<0.05 threshold indicated a non-significant relationship between rice and rainfall. In other words, rice does not depend on rainfall. This is not the case for corn, where the linear regression equation was found to be significant with b=0.395, (1,34)=-0.606, p<0.05. On the other hand, with respect to cultivated areas, the results show that rice production is highly dependent on it. The linear regression equation was found to be significant with b=0.679, (1,34)=2,485, p<0.05. Adjusted R² is 44.5%. It is even more significant for corn with an adjusted R² of 100%.

The current situation of water resources and their uses in the Sisseb El Alem Nadhour Saouaf basin (Central Tunisia) is under strong pressure; human activities and climate change. To arrive at a realistic assessment of the underground water reserves in this basin, a diversified hydrogeological database was created (data from hydraulic and oil drilling, seismic sections, electrical surveys and gravimetric). A structural model is built and validated for the study area. Such a geomodel results from a geological interpretation, which makes it possible to identify the sedimentary series present and to specify their spatial and chronological relationships. This 3D geological model was integrated to Modflow model to assess the flow dynamic and to calculate the water budget. Many simulations were performed. The balance budget over 2020 will be in deficit -14.22 Mm3 and the aquifer will remain in a critical situation: the exploitation will be of the order of 75.43 Mm3. This depends enormously on the progress of the method of extraction of groundwater and over 2030: the global water budget is also deficit -14.5 Mm3.

The National Science and Technology Museum launched the «Explore IOT Exhibition» in 2017. When curating the exhibition, it included the exhibit education activity: «DIY Unmanned Aerial Vehicle» in its planning to respond in a real time manner to the emerging issue of incorporating information, communication and digital technology into the Curriculum Guidelines for the 12-Year Basic Education, displaying the Museum’s function in supporting formal education. Museum has to be innovative in terms of educational activity to meet various groups’ learning needs. Using «DIY Unmanned Aerial Vehicle» activity as an example, this paper discusses the generic learning outcomes (GLOs) of non-formal educational institutions used in said activity to plan further activities and conduct learning evaluations. The objective is to see if it is feasible to practically use GLOs for the Museum’s educational activities. The results of a qualitative and quantitative data analysis show that most participants gave positive feedback to learning effectiveness, attesting to learning goals based on the framework of GLOs set by the organizer. GLOs make it easier for the organizer to focus on the direction of the activity. The findings from this case study suggest that GLOs can serve as a reference for promoting the Museum’s educational activities.

Introduction: Glycogen storage disease type I is a rare hereditary metabolic disorder, caused by a deficit of the glucose-6-phosphatase, an enzyme that catalyzes hydrolysis of glucose-6-phosphate to phosphate and glucose, inducing essentially hypoglycemia, hyperlactacidemia, hyperuricemia and hyperlipoproteinemia often at the expense of triglycerides. Hypertriglyceridemia is often moderate (<10 g / l) at the time of diagnosis, but in the long term, it can exceed 20g/l causing serious complications such as acute pancreatitis or hepatic adenoma. We report a case of glycogen storage disease type I revealed by major hypertriglyceridemia.Case report: A 10-month-old infant girl, with a family history of storage disease type I (brother), admitted to the pediatric department for recurrent seizures due to hypoglycemia evolving for 2 months, and hepatomegaly. The blood tests made on admission revealed a hepatic cytolysis with a liver enzyme level 5 times upper the limit of normal, a major hypertriglyceridemia at 10 g / l (<1.5 g / l), and a correct glycemia and uricaemia. The infant was put on an adequate diet therapy. The evolution was marked by good clinical improvement.Conclusion: Major hypertriglyceridemia is a metabolic abnormality often occurring during the course of glycogen storage disease type I, but sometimes it is discovered at the time of diagnosis requiring prompt management and strict monitoring to avoid complications.

In order to preserve the ecological quality of Aby lagoon, the aim of this study is to determine, according to seasons, spatiotemporal distribution and origin of phthaltes in the sediments of this lagoon. To do this, from September 2007 to July 2009, during seasonal sampling campaigns, sediment samples were collected at twenty (20) stations distributed along Aby lagoon. Analysis of the sediment samples, using gas chromatography-mass chromatography (GCMS- QP2010 plus), revealed presence of eight phthalates in the lagoon’s sediments. These are dibutyl phthalate (DBP), di (2-ethylhexyl) phthalate or bis (2-ethylhexyl) phthalate (DEHP), dimethyl glycol or di (2-methoxyethyl) phthalate (DMEP), phthalate di (2-methylpropyl) or diisobutyl (DIBP), dihexyl phthalate (DHP), di-isodecyl phthalate (DIDP), butyloctyl phthalate (BOP) and didecyl phthalate (DDcP). Areas of high population density as well as areas under the influence of the rivers that feed Aby lagoon contain more phthalates. However, the area under oceanic influence is free of phthalates. Statistical processing of data, using STATISTICA 7.1 and ADE-4 softwares, showed that the phthalates are continental and anthropogenic origin.

Since practically the 2000s, Morocco has continued to consolidate its National Innovation System (INS), in order to create an environment conducive to innovation. The Moroccan government has put in place a number of plans and devices, aimed at giving new impetus to innovation and catching up with the delay recorded in this area, compared to developed countries, but above all, compared to emerging and competing countries. Also, he initiated several legal and institutional reforms, which led to the emergence of a set of institutional actors, constituting the backbone of the Moroccan INS, such as political support bodies, the system of research, networking structures, support infrastructures, all at the service of innovative companies. The analysis of the path of consolidation of the Moroccan INS teaches us the existence of several obstacles, of a structural nature, likely to prevent its maturation and, consequently, its role in the dynamics of learning.

The aim of this methodology is to combine Arab musical characteristics with various modern compositional techniques, and to study these works, we have relied on several references and studies concerned with musical analysis and Western musical theories, which can be used in Arab maqam music that includes various analytical methodological bases. Whereas, the proposed analytical study includes four analytical aspects represented mainly in the melodic aspect, the rhythm side, the performance aspect and the harmonic analysis, which are the basic elements for analyzing the melodic themes that make up each effect, considering the structural division. In addition to the possibility of adopting it also in improvisational musical works (rhythmic or free), this study also contains a section in which we deal with the constants and variables occurring in the musical effect, depending also on the analytical elements included in this proposal.

Since the 1960s, Côte d'Ivoire has experienced a decline in forest areas in favor of humanized areas due to the establishment of cash and food crops. The Nassian sub-prefecture is not on the sidelines of this degradation. The objective of this research is to analyze the land use and the impact of anthropogenic activities on the natural environment in the Nassian sub-prefecture from 1998 and 2018. The methodology was based on a cartographic, analytical approach. based on the use of remote sensing and geographic information systems (GIS). Carrying out this study required the use of satellite and cartographic data and field surveys. The results indicate a transformation of natural spaces by human activities. Thus, the sub-prefecture initially made up of forests and savannahs deteriorated in favor of humanized areas (crops / fallow, habitats / bare soil) from 1998 to 2018. The analysis indicates that from 1998 to 2018, the transformation of the environment is changing at a rapid pace. There is a regression of natural spaces in favor of humanized spaces. Natural areas have gone from 64% to 37%. Humanized spaces have progressed at the expense of natural spaces. They went from 36% to 63% from 1998 to 2018. We are witnessing human pressure on the environment and degradation of the plant cover.

Climate change is putting significant pressure on agricultural activities. This chapter aims to analyze the perceptions of climate variability by cereal producers in the far north of Benin. To achieve this objective, meteorological data (temperature, precipitation and relative humidity) from the period 1970 to 2018, socio-demographic data and agricultural data were used. Instat + and SPSS software enabled the analysis of the agro-climatic parameters of the season and the survey data on the local perception of the populations, respectively, in the form of tables and graphs. The results of the work reveal that the grain producers in the study environment perceive climate variability. Rising temperatures (94.86%), flooding (67.19%) and drought (58.6%). The analysis of climatic risks (precipitation, temperature and humidity) confirms the perception of these producers. Indeed between 1970 and 2018, the trends in precipitation and temperature are on the rise with increasing humidity.

This research proposes to contribute to the study of port competitiveness. Given the lack of unanimity of previous studies, we will try to overcome some shortcomings that we have detected in studies dealing with the subject of port competitiveness and propose a theoretical framework to describe this concept under three foundations theoretical: port competition, competitive advantage and relativity.
