Le chrome est l’un des métaux les plus largement utilisés dans l’industrie. Aujourd’hui, suiteau non-respect ou à l’insuffisance des lois en vigueur ou à des accidents, un grand nombre desites et d’anciens sites industriels sont pollués par du chrome. La forme hexavalente, que l’onretrouve dans les rejets industriels, est considérée parmi les polluants les plus solubles dansl’eau et les plus toxiques à cause de leurs propriétés cancérigènes. Cette solubilité lui confèreune grande mobilité dans les écosystèmes. La réduction du chrome (VI) en chrome (III) permetde limiter sa mobilité et sa toxicité et ainsi de réduire les impacts écotoxicologiques potentiels.Le sol, pollué ou non, contient une microflore abondante qui peut dans certains cas métaboliserles substances polluantes et ainsi réduire le caractère toxique de certains composés. De plus enplus de travaux de recherche tentent d’exploiter ce phénomène de « dépollution naturelle » afinde mettre au point des procédés de traitement biologique des rejets pollués. Ces procédéspourraient être utilisés en complément des procédés physicochimiques, thermiques etélectrochimiques déjà existants.

ABSTRAK Penelitian ini bertujuan untuk merancang sebuah materi ajar khusus untuk pengajaran Bahasa Arab di Madrasah Tsanawiyah “Mansyaul Ulum” berdasarkan pendekatan komunikatif kambiumi. Tidak adanya bahan ajar sebagai sumber bagi guru dan siswa dalam melaksanakan aktifitas belajar mengajar yang efektif di madrasah adalah dasar pijakan penelitian ini. Untuk itu, peneliti melihat bahwa pendekatan komunikatif kambiumi sangat cocok dengan tujuan utama pembelajaran Bahasa Arab dan motivasi siswa untuk belajar Bahasa Arab disekolah tersebut. Penelitian ini adalah penelitian pengembangan dengan menggunakan pendekatan kualitatif, serta memakai langkah-langkah penelitian pengembangan yang dikemukakan oleh Sugiono dengan modifikafi. Adapun subjek coba dari penelitian ini terdiri dari 53 orang siswa dan guru bahasa arab di Madrasah Tsanawiyah Mansyaul Ulum. Teknik pengumpulan data menggunakan observasi, wawancara, dan angket. Sedangkan pengolahan datanya menggunakan teknik analisis isi, analisis deskriptif dan analisis statistik deskriptif. Penelitian ini Menghasilkan Sebuah buku ajar untuk kemahiran berbicara yang disusun dengan menggunakan pendekatan komunikatif kambiumi untuk Madrasah Tsanawiyah Mansyaul Ulum gondanglegi malang. Hasil dari validasi yang telah dilakukan oleh para validator pembelajaran Bahasa Arab terhadap bahan ajar ini secara umum dinilai “baik sekali” sedangkan hasil analisis data yang didapat melalui angket ataupun wawancara dengan guru bahasa Arab menunjukkan bahwa kecocokan bahan ajar ini untuk diterapkan di Madrasah Mansyaul Ulum dinilai "baik sekali” Dan Penggunaan produk bahan ajar yang telah didesain memiliki efektifitas yang sangat baik di dalam peningkatan keterampilan berbicara para mahasiswa. ABSTRACT This research was intentionally performed to design a specific Teaching Materials for teaching process of Arabic language at the Junior Islamic high School “Mansyaul Ulum Gondanglegi Malang” based on Communicative approach cambiumy. The reason of choosing this topic was the absence of an integrated Teaching Materials which can be used as a guide for teachers and students to perform an effective learning and teaching process in that school. The author assumed that the Communicative approach cambiumy is relevant with the main goals of Arabic teaching in this school and useful to motivate the students to learn Arabic language. This development research with qualitative approach, used a model proposed by Sugiono. The subjects of the research were 53 students and teacher of Arabic language from the Junior Islamic high School Mansyaul Ulum. The data was collected by using observation, interview, and questionnaire. The data was then analysed by using a content analysis technique, a descriptive analysis and a descriptive statistic analysis. This study result a Teaching Materials to Improve Speaking Skill Based on Communicative Approach Cambiumy for the Arabic language teaching at the Junior Islamic high School Mansyaul Ulum. The final assessment of this designed Teaching Materials from the validators resulted the score which means “very good”. The result of data analysis obtained from the questionnaires and interview with the teachers shows that the suitability of the designed teaching materials to be applied at the Junior Islamic high School Mansyaul Ulum has a score which means “very good”. and the experiment appointed that using product handbook could improve the ability of students to speak Arabic.

Border zones in post-conflict cities are the locus of collective imaginaries inducing memories of sectarian divides, and instigating attempts at urban integration with narratives of peace and reconciliation. Post-war reconstruction plans have favored the neutralization of border zones through urban renewal projects, unresponsive to the evolving identity of their adjoining districts. This thesis intends to re-conceptualize border zones as both segregators and integrators, to be reinforced, negotiated, or ‘fluidified’ with reference to the realities of their district’s context as well as to the overall city dynamics. The case study focuses on the Southern entrance of Beirut’s Central District along Damascus Road (a segment of the former Green Line) and examines its transformation from a combat zone into a transitional and unresolved interface polarized between two district identities; to the East, a campus district typified by Saint Joseph University (USJ), and to the West a corporate development precinct epitomized by Beirut Digital District (BDD). The thesis proposes a set of context-sensitive urban design strategies for enhancing streetscape identity, improving vehicular and pedestrian connectivity, and providing a framework for private development aimed at strengthening the responsive capacity of Beirut’s former Green Line as a resilient interface.

Observed variables often contain outliers that have unusually large or small values when compared with others in a data set. Some data sets may come from homogeneous groups; others from heterogeneous groups. Outliers can be caused by incorrect measurements, including data entry errors, or by coming from a different population than the rest of the data. The Appearance of the outlier Values in the set of data may effect on the result of the statistical Analysis of data, from this point of view appears the Importance of detecting the outlier values in any set of data before study. To detect the mentioned outliers, we have used formal and informal methods. Whatever, this study aimed at making a comparison among the detection outliers methods (formal and informal methods) to discover the best in detecting outliers. To achieve this goal, we have simulated 4 samples with different size which follow the normal distribution N(0,1). The sizes of these samples are: 20, 100, 500 and 1000. Another elements which follow the normal distribution N(0,1.5) had been added to the previous samples with a percentage of 20% for each one. The new sizes became 24, 120, 600 and 1200. After applying these methods (formal and informal) on the samples to detect the outliers, we have noticed that: Tukey which is an informal method had the highest sensitivity in detecting outliers, next one is MAD and then the modified Z-score. Z and SD methods were of low sensitivity in detecting outliers. For formal methods, Quartile and Hample methods were the most effective in detecting outliers, next one is ESD. Dixon is not appropriate in detecting outliers in samples more than 30 elements. Grubbs was of low sensitivity in detecting outliers. We have applied the mentioned methods on a medical data set of body mass index (BMI) with a sample of 309, this sample was of patients of UN sanitation center in Khanyounis, their ages were ranging between 25- 50 years old. Results were the same of simulation study as Hample and Quartile as formal methods were the most effective in detecting outliers and Tukey as informal method was the most effective then MAD.

In the present work,we are interested to the study of the adsorption of Malachite green, it iscationic dye .For this work we use catalyst NiO-MgO synthetised by two methodsautocombustion and impregnation , calcinated at 700°C for 2h , characterizes by XRD andSEM analysis than applied on the elimination of Malachite green by adsorption process .Theexperimental results showed that the NiO-MgO prepared with autocombustion is moreefficient in adsorption then NiO-MgO impregnation due to the IP due to the smallestcrystallite size 8 nm compared to 28nm in case of NiO-MgO AT. The study of the influenceof the pH dye, the initial concentration of pollutant and the adsorbent mass showed us thatthe optimal adsorption of malachite green is on this condition (C0 = 30 ppm, pH=10, T=25°C,m=0.04 g) after 55 min of reaction.
