Congenital hernia of the diaphragmatic dome (CHDD) is an embryonic malformation in which all or part of the diaphragmatic dome fails to develop properly. In the majority of cases (80% to 90%), this malformation affects the left posterolateral part of the diaphragm, while in 10% to 15% of cases it affects the right. Bilateral cases are extremely rare, accounting for less than 1% of cases. This malformation is estimated to occur at a frequency of around 1 in 3500 births, with a male predominance. The diaphragmatic defect causes the abdominal organs to rise into the thoracic cavity during critical phases of lung development. These anomalies result in bilateral pulmonary hypoplasia, a reduced number of pulmonary vessels, and pulmonary arterial hypertension (PAH). The combination of these anatomical and functional anomalies, in varying degrees, explains the wide variability of symptoms at birth. Diagnosis is usually made prenatally by ultrasound, which enables severe forms of the disease to be detected and appropriate management initiated. The prognosis remains generally grave, with a neonatal mortality rate of between 30% and 60% depending on the study, and around half of all children will have long-term sequelae.

In order to investigate the role of TiO2 during plasma treatment, the degradation of the dye AO7 has been studied by gliding arc discharge in the presence of a TiO2 catalyst （CGAD）. The results revealed that the adsorption of the dye on TiO2 is a physical adsorption in accordance with Langmuir isotherm, with a constant of adsorption KL ： 0.52 mg/L and a maximum adsorption capacity b = 18.1 mg/g. The temperature variation of the reaction medium made it possible to consider thermodynamic parameters. Indeed, the adsorption is exothermic （enthalpy： △H 〈 0）, and spontaneous （free enthalpy： △G 〈 0）. The negative entropy （△S 〈 0） confirms the affinity of the dye molecules for TiO2. 20 min of CGAD treatment in the pres- ence of an optimal quantity of TiO2 （2 g/L enabled us to bleach the solution of AO7 （100 μM） completely. The discoloration rate with and without the addition of TiO2 was 100% and 28%, respectively. 40 additional minutes of treatment allowed a total abatement of the chemical oxy- gen demand. The elimination of AO7 molecules during the plasma-catalytic treatment follows Langmuir-Hinshelwood （L-H） model kinetics. According to this model, the speed constant is kr = 14.97 mg-L-1 ·min-1 and the adsorption coefficient is KL-H= 0.010 L/mg. The latter being negligible compared to kr, adsorption is therefore weakly performed during the plasma treatment.

In the recent past years, the major challenge facing scientists and researchers in the field of knowledge engineering is classifying and sharing geographic data with both computer and human. Ontology is one of the most important classification schemes that aim to make data machine-interpretable. In the literature, all ontology based models developed in the field of urban planning have some limits. First, they describe the nature of each parcel of the soil while ignoring other important components of urban planning such as services, infrastructure … Secondly, these ontologies are developed according to legislation and regulations of the zone studied so they can’t be used by some urban territories that have specific urban law such as Moroccan country. This paper presents a new multi-dimensional ontology model called LUP specifically developed to overcome this flaw. The main goal is to provide semantic land use descriptions according to four dimensions: zoning, services, infrastructure and easement and to define all LUP concepts within the Moroccan urban law. We illustrate the use of our proposed model with a case study by mapping a land use planning document within the area of Ainchock municipality of Casablanca city according to our model concepts.

The magnetic properties of Ni/Cu multilayers, prepared by the electron beam evaporation method under ultra high vacuum conditions, have been systematically studied by magnetic measurements. The temperature dependence of the spontaneous magnetization M (T) is well described by a T3/2 law. A spin wave theory has been used to explain the magnetization versus temperature. Based on this theory, the approximate values for the exchange interactions have been obtained.

Background and Aims: Crohn’s disease is a chronic inflammatory bowel disease (IBD). Endoscopy and radiology play an important role in the diagnosis and management of this specific disease. The ability of each of these two tests to detect the gastrointestinal involvement (ulceration, stenosis, fistula, polyp, mucosal thickening) varies according to the type of Crohn’s lesions. The purpose of our study was to evaluate the correlation between these two diagnostic methods in the detection of those specific lesions in 70 patients diagnosed with Crohn’s Disease (CD) during the period of 3 years. Methods: In this retrospective study, including 70 patients with Crohn’s disease, Four major characteristic lesions (ulceration, stenosis, fistula and polyps) were studied by endoscopy and radiological exams to evaluate the relationship between endoscopy and imaging findings in the detection of these lesions. The analysis of our results was made by statistical analysis system: EpiInfo and SPSS. Results: The concordance of each of these diagnostic modalities is average for stenosis and fistulas and low diagnostic significance for ulcers and polyps. However, the imaging features of mucosal thickening are sensitive but not specific.
