Several studies were realized on the swelling phenomena of soils. This phenomenon which still remains non controllable, cause great damages on buildings all throughout the world. All the investigations done till now, have as objective to mitigate the extent of these damages through improving our knowledge on the swelling soils behavior and controlling factors responsible for this behavior. In this context, the present study represents a contribution to the stabilization of two clays, the M’Zila(Sidi Ali-Mostaganem) and the Bourmadia(Relizane). It can be found in the literature, several stabilization procedures of expansive soils. For the sake of promoting certain materials, the Beni-Saf ‟s pouzzoulana is used for the stabilization work. It will be presented in this study, experimental results obtained from different tests of characterization i.e: mineralogical, mechanical and oedometer tests. These tests will allow us on one hand to determine certain characteristics such as: constituents of the clays, mineralogical properties, Atterberg limits, mechanical properties, and also pressure and potential of swelling. On the other hand, these tests and particularly the oedometric tests will permit us to carry out stabilization tests by the addition of pouzzoulana.

Titanium carbonitride is a material of high technological interest because of its beneficial proprieties including high hardness, low friction and chemical inertness. Chemical Vapor Deposition (CVD) processes are used, in a long time, to produce TiCN thin films. But the high substrate temperature condition work causes thermal damage to the deposited films and the substrate. But the physical vapor deposition (PVD) is mostly used because it’s an environmentally technique for coating deposition it’s used at relatively low substrate temperature. The sputtering is used for depositing TiCxNy films, the films properties are widely changed by the variation of the sputtering conditions, such as reactive gas pressure, total pressure, and substrate bias voltage. Therefore it was interesting to study the effect of the deposition parameters on deposited films.In this study, titanium carbonitride thin films have been deposited on silicon, glass and steel substrates by reactive RF sputtering (13.56 MHz) from a pure titanium target in Ar-CH4-N2 mixture. The main variables investigated are the composition of the CH4-N2 gas mixture, the total pressure, the discharge power, substrate bias, and the deposition time. The microstructure and chemical composition of the coating were studied respectively by X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS). The optical and electrical properties will be discussed and correlated to the deposition parameters.

The rapid development of wearable applications based on 5G networks has led to an urgent need for specific antenna types. These antennas must have low power consumption, small size, great flexibility, and other features.Thus, the microstrip antenna is the best choice for these applications. In this thesis, a dual band antenna has been presented for 5G wearable applications. The proposed antenna operates in 6GHz and 28GHz frequencies, which are within the 5G frequency bands. The antenna design is simulated and validated by two-simulation softwares: Computer Simulation Technology (CST-Studio) and High-Frequency Simulation Software (HFSS). The Arlon AD 250C, Rogers RT/droid 5880(tm), and FR4 materials are used as substrates, in addition to the copper as a patch and ground. The simulation results show that the Rogers RT/droid 5880(tm) material has the better performance compared to other materials. However, the FR4 material is used in the fabrication process due to the unavailability of the Rogers RT/droid 5880(tm) in the Iraqi materials. The propose antenna has been designed with four feeding methods: Microstrip line, Coaxial (coplanar feed), Proximity coupled, and Aperture coupled. The simulation results shows that the Aperture coupled method has the best results over the other methods. Where, the antenna parameters with the Aperture coupled method are determined as follows:S11 values are -69.2dB and 23.2dB at 6GHz and 28 GHz, respectively, in addition, VSWR values are 1.006 dB and 1.14 dB at 6GHz and 28 GHz, respectively. Furthermore, the gain and efficiency values are (3.72 dB & 65.7%) and (7.07 dB & 97.5%) for 6GHz and 28 GHz, respectively.These results and other are compared with some literature results and this comparison shows that the proposed antenna outperforms the previous works.The folding ability of the proposed antenna has been tested by bending it on cylinders with different radii. Where, the simulation results show that the folded antenna versions have the same performance as the original one. Finally, the fabrication results show the fabricated antenna has a problem due to the air gap between the antenna’s substrates, which left because the hardiness of the FR4 material. However, the performance of the fabricated antenna has been corrected by compressing the both substrates during the test process.

TheObjectives of this study were to detect the common medical problems,to assess the psychosocial profile and to identify factors associated withoffending.Self administered ISAAC questionnaires with supplementedquestion on sociodemographic data, drug history (substance abuse),features of both medical and psychiatric problems were included.Detailed information about the offence were stated. Anotherquestionnaire; strength and difficulties questionnaire which is abehavioral screening covering items on psychosocial attributes was alsoadministered. Complete physical examination was recorded.The age of the detained children range from 10-17 years. Therewas obvious male predominance in the study. The majority of childrenbelong to Foar (49%), Nilotic (26%) and Gaaleen (17%) tribes. Most ofthe parents were from states other than Khartoum (61%). The majorityof the children belong to a low social classes (94.2%). The main reasonsfor placement were condemnation (43.3%) which were mainly due tofinancial causes (27.9%).The most common health problem was substance /alcohol abusewhich was reported in (54.1%), followed by dermatological conditionswhich accounted for (30.8%). Intestinal parasitism were reported by(11.6%). Enuresis was found in (11.6%), schistosomiasis affected (6.1%)and upper respiratory tract infection which was encountered by (6.7%).The prevalence of HBV was (4.9%). Psychiatric disorders werediagnosed in (40%) which were mainly conduct disorders (33.3%), withan overlapping between different types of psychiatric disorders. Beingan offender was significantly (P. value < 0.000) affected by the state ofpoverty; however, it was not affected by the state of being from verylarge families, other offender in the family, poor education or repeatedoffending.It concluded that the common health problems are substance/alcohol abuse, dermatological problems and intestinal parasitism.Psychiatric disorders were diagnosed in 40% of the children withconduct disorders (83.3%) being the most common.Being an offender was significantly (P. value < 0.000) affected bythe state of poverty.
