Estimation & Cartography the Water Erosion by Integration of the Gavrilovic "Epm" Model using a Gis in the Mediterranean Watershed: Oued Tleta (Western Rif, Morocco)
265-278
Aman Allah Zahnoun and Jamal Al Karkouri
Abstract:
The watershed of the Oued Tleta (178 km²), situated in the north of Morocco, on the Mediterranean side of the Western Rif, is characterized by a subhumid bioclimate and heavy (700 mm) and irregular rains and heavy anthropogenic pressure. This has had the impact of surexploitation of natural resources in general, and soils in particular. Excessive use of agricultural land has led to its fragility and exacerbated its susceptibility to erosion. These natural and anthropogenic conditions have induced a rather intense erosive dynamic which is visible by various forms, sheet erosion stripping, gully erosion and landslides. This erosive dynamic leads progressively and inevitably to impoverish the soils of the catchment area and to the siltation of the Ibn Batouta dam located downstream of the Oued Tleta, hence the interest of this study. The application of the "EPM" model for estimating soil losses makes it possible to approximate the severity of the erosive phenomenon. The average soil losses by water erosion according to the model used are estimated at 46.1 t/ha/year. The maximum losses are of the order of 294 t/ha/year per plot. Total annual watershed losses are close to 800,000 t/year (Plot Erosion). In addition, the analysis of these results made it possible, using the GIS, to determine the factors that control water erosion and that are in order of importance: the sensitivity of soils to erosion, slopes, soil protection, precipitation, types of erosion, and temperature. It should be noted that the used methodology of EPM model applies to various types of erosion.

Abstract:
In a complex hospital environment, where in many cases the demands for a quality in Clinical Engineering are high and resources are low, it is important to apply tools that can assist at improving services provided by clinical engineering’s professionals. Thus, this paper aims to apply the QFD methodology as an aid tool in planning the quality of service provided by the clinical engineering team of Onofre Lopes University Hospital, with the intention of proposing improvements to be included in future planning. Initially, this research aims to discover the main needs of healthcare professionals that use services provided by the clinical engineering team, by reviewing articles on quality at hospitals environments. The target sectors of this research were chosen using as criteria the highest number of work orders (OS) generated and criticality of equipment. It is also object of study to analyze the level of satisfaction and importance that the employees of the studied sectors attribute to the clinical engineering sector. This study was conducted through semi-structured interviews, which were granted by the heads and coordinators of each sector. After completing the previous step, the quality house was built starting with translating users' needs into design requirements, and then correlating existing design requirements with finding out which design requirement is of highest relevance to meet customer needs. In the end, it will be possible to generate data that can be interpreted efficiently by the clinical engineering team, thus identify which points are working as expected and which need to be analyzed more closely in future strategic planning.

A Critical Reading in Malek Bin Al-Raib’s Lament
329-336
Muyassar Saleem Al-Shora
Abstract:
This study is considered from the most famous of what had been in the art of “lamentations” in the Arab Poetry, for what it enjoys of bravery and truthfulness that both spring from the inner-self of the Poet Malek Bin Al-Raib, where nothing precious matches the psyche, so feelings intermixed about a decisive issue, and the smell of death penetrated into the directions of the place, it fragranted in his breaths so he drew them painful words catch the receiver with infection, so he lives it a moment by moment and shares the poet his pains, cares, and alienation. All that is done by the text, so I could discover the relationship between the images formed by the poet in this imagination and the psychological state that accompanies this production, through the first chapter of study. And also the reader can disclose some semantics of the text, that is, through his interaction with a truthful sentiment together with poem. But what relates with the second chapter. We glance the ascension of the “ego” and this ‘self’ sighs. This means the psychological state at the poet and appearance of death marks at a great from represented with meanings of mutual consolation, sorrow, and scenes of weeping and lamentation that are in harmony with the decisive end of the poet.

L’étude a été menée dans le centre agricole d’Agricongo situé à 17 Km de Brazzaville. Le but de cette étude était d’évaluer les effets des usages des sols sur les caractéristiques chimiques et microbiologiques des sols. Sept sites ont été choisis dans la zone d’étude : S1 Jachère d’herbe avec légumineuse plantée ; S2 Jachère d’herbe ; S3 jachère avec enfouissement de fanes de niébé; S4 culture de soja ; S5 jachère d’herbe (7 ans) ; S6 plantation de caféier et S7 verger dans lesquels des échantillons composites de sol ont été prélevés dans les horizons 0-10 et 10-20 cm. Les analyses ont porté sur la détermination du pH, du carbone total, de la biomasse microbienne, du phosphore total et assimilable. Les résultats ont montré que le pH diffère entre les horizons et entre les sites. Le taux de carbone total le plus élevé a été enregistré dans le site1, 16,8‰ et 12,4‰ respectivement dans l’horizon 0-10 cm. La biomasse microbienne carbonée la plus élevée a été observé dans S1 de l’horizon 0-10 cm avec 309,5 µg / g sol. Les teneurs en phosphore total ont varié entre 66,88 mg/kg de sol dans le site 4 et 35,14 mg/kg de sol dans le site 1 dans l’horizon 0-10cm. A l’exception des sites 1 et 7 les teneurs en phosphore assimilable sont plus élevées dans l’horizon 0-10 cm que dans l’horizon 10-20cm. Les résultats obtenus montrent que les changements d’usage des sols impactent fortement les caractéristiques chimiques et microbiologiques des sols.

Ihejiamazu, Christiana Chinyere, Neji, Hope Amba and Isaac, Ashiwere Obogo
Abstract:
Science process skills knowledge is essential if effective learning of science at all levels of education must be achieved. The knowledge of science process skills helps the learner to develop formal thinking ability and thus appreciate the relevance of science in everyday life. The aims of this study were to investigate the relationship between Senior secondary school II Biology students’ knowledge level of science process skills and their attitudes toward science, the effect of gender and class size on students’ knowledge level of science process skills. Three null hypotheses were formulated to guide the study. A sample of 350 (SSII) Biology students was used for the study. The instrument used for data collection were Process Skills Correlates Questionnaire (PSCQ) and Process Skills Knowledge Test in Biology (PSKTB). The reliability of the PSCQ was established using Cronbach Alpha Statistics and Kurder Richardson formula 20 (KR20) for PSKTB respectively. The reliability estimate ranged from 0.77-0.78. Pearson Product Moment Correlation Co-efficient statistics was used to test hypotheses one and two whilst independent t-test was used in testing hypothesis three at 0.5 levels of significance. The results of analysis revealed that attitude and class size has significant correlation with students’ science process skills knowledge. However, gender does not significantly influence Biology students’ science process skills knowledge. Based on the findings, it was recommended among others that government should build more equipped classroom blocks in secondary schools that will reduce crowded class size in schools for effective teaching and learning of Biology.
