Abstract
INTRODUCTION Behçet's disease is a systemic disease of unknown etiology. Its ocular manifestations are multiple and polymorphic, with uveitis at the top of the list. Classically, uveitis in Behçet's disease does not cause elevation of intraocular pressure. However, this may be found in 10 to 20% of cases, secondary to trabeculitis, trabecular obstruction by inflammatory cells, anterior or posterior synechiae, or induced by prolonged use of corticosteroids. Its occurrence is a major complication, the management of which is especially delicate when glaucoma occurs. The purpose of this study was to study the factors predictive of glaucoma in Behçet's disease. MATERIALS AND METHODS This is a retrospective study of all the charts of patients consecutively hospitalized for Behçet's disease over a period of 8years in the ophthalmology A department of the specialty hospital of Rabat university medical center. RESULTS Fifty patients were treated for Behçet's disease during the study period. There were 41 men (82%), and 9 women (18%). Glaucoma was diagnosed in 11 patients (22%). The mean age of this subgroup was 31years, with a gender ratio of 6 women/5 men. The glaucoma was associated with anterior synechiae in 4 cases, primary open-angle glaucoma in 5 cases, neovascular glaucoma in 1 case and seclusio pupillae in 1 case. Therapeutically, all patients were on glaucoma eye drops, and five underwent filtering surgery. Statistically, on univariate analysis, ocular hypertension was observed particularly in patients with low initial visual acuity (less than 1/10) (P=0.001), with severe posterior segment involvement, especially retinal vasculitis (29% vs. 6%, P=0.04), macular edema (40% vs. 4%, P=0.001), and optic disc edema (50% vs. 15%, P=0.02). A high number of recurrences was also associated with glaucoma (1.0 vs. 3.0, P<0.0001). On multivariate analysis, low baseline visual acuity, presence of retinal vasculitis, and high number of recurrences were independent risk factors for ocular hypertension in our patients followed for Behçet's disease. CONCLUSION Glaucoma can complicate the management of Behçet's disease. This glaucoma will be more difficult to manage in this delicate pathological context. It requires special vigilance in patients with severe posterior segment inflammation, to institute effective management to avoid its potentially blinding complications.

Abstract
In this work, we have studied, formulated, prepared, and characterized the rheological and electrical behavior of a composite material based on an epoxy resin Diglycidyl Ether of Bisphenol A (DGEBA) reinforced with hexaglycidyl cyclotriphosphazene (HGCP). The epoxy system was cured with 4,4’-methylene dianiline (MDA). DGEBA-HGCP-MDA epoxy composite materials with reinforced HGCP which varied from 5% to 10% by weight were prepared by mixing in the molten state. The morphology was evaluated by SEM. The rheological behavior was studied using small deformation rheology. The electrical characterization was carried out with a frequency variation range from 1 Hz to 100 KHz at room temperature. These measurements revealed that the rheological and electrical behaviors strongly depend on the quantity of HGCP in the DGEBA matrix. The linear viscoelastic properties study reveals that the modulus of elasticity G’ is dependent on the amount of HGCP present in the epoxy resin DGEBA. The capacitance-frequency measurements suggest a distribution of localized states in the band gap of the blends.

Abstract
PURPOSE To analyze clinical, therapeutic and prognostic features of pediatric Vogt-Koyanagi-Harada (VKH) disease. MATERIAL AND METHODS This retrospective study included 16 eyes of 8 children diagnosed with VKH disease followed at a teaching hospital over a 10 year period. Diagnosis was based on the revised criteria of VKH disease. All data were analyzed using SPSS® software. RESULTS There were 62.5% girls and 37.5% boys. The mean age (years) was 14.6±4.4. The mean follow-up (months) was 38.7±28.7. The mean initial visual acuity (VA) (LogMAR) was 1.4 with 68.8% of eyes presenting with severe visual loss at admission. The median time (days) required for resorption of the serous retinal detachment was 10 [8.25-25]. Extraocular signs were present in 62.5% of cases. The mean time until initiation of treatment was 25.6 days. 62.5% of patients received corticosteroids alone, and 37.5% of patients received a combination of corticosteroids and immunosuppressive therapy. Final VA was 0.4 [0.1-2.3]. In our study, the time until consultation, low initial VA and recurrences were statistically associated with severe visual loss (P≤0.05). CONCLUSION Life expectancy in pediatric cases of VKH disease justifies the early initiation of immunosuppressive treatment or even biological therapy to achieve better steroid sparing and preserve visual function.

Abstract
The aim of the present work is to monitor the flocculation process using the analysis of the electric and dielectric properties. Therefore the dielectric and electrical characteristics of wastewater with different cationic polymer concentrations were investigated via the impedance spectroscopy (IS) method. Impedance measurements were carried at different concentration of cationic polymer in the frequency range from 0.1 Hz to 100 kHz. The analysis of complex permittivity spectra was described by the superposition of a power law at a low frequency related to the diffusion process and Cole-Cole relaxation behavior at high frequency. Moreover, an equivalent circuit model was developed in order to analyze the experimental data and to further investigate both processes. The variation of the parameters extracted from the equivalent circuit with the increase of cationic polymer concentrations has shown a net transition at 10 mg/l. This behavior could reflect the flocculation of dispersed particles at 10 mg/l. The findings in this work could draw new attention toward the monitoring of the coagulation-flocculation process using impedance spectroscopy and could be extended to other kinds.

Abstract
In the present review, we have been able to describe the different families of dyes and pigments used in textile finishing processes (Yarns, fabrics, nonwovens, knits and rugs) such as dyeing and printing. These dyes are reactive, direct, dispersed, indigo, sulphur and vats. Such that their presence in the liquid effluents resulting from the textile washing constitutes a serious risk, in the absence of their purification, for the quality of receiving aquatic environments. Indeed, the presence of these dyes and pigments can cause a significant alteration in the ecological conditions of the aquatic fauna and flora, because of the lack of their biodegradability. This has a negative impact on the equilibrium of the aquatic environment by causing serious dangers, namely the obvious dangers (Eutrophication, under-oxygenation, color, turbidity and odor), the long-term dangers (Persistence, bioaccumulation of carcinogenic aromatic products and formation of by-products of chlorination), mutagenicity and carcinogenicity.
