Series of novel dichromophoric cyanine dyes based on 2-aminobenzothiazoles and 3-amino-1,2,4 -triazole have been synthesized in high yields. All the dyes have been classified as disperse dyes. Besides their electronic spectroscopic properties, high dye-uptakes on polyester, excellent fastness properties, highly extinction coefficients, and broad solvatochromic effects have been observed in thes...

The molecular structure, UV-visible spectra, and optical properties of D-π-A conjugated organic dye molecules (Disperse Red 1 (DR1) Disperse 73 (DR73)) were analyzed using density functional theory (DFT) time-dependent (TD-DFT) compared with azobenzene molecule to study the effect donor acceptor substituents on properties. performance DFT functionals is investigated B3LYP hybrid three long-rang...

This paper was aimed to study the efficiency of forward osmosis (FO) process as a new application for treatment wastewater from textile effluent and factors affecting performance process.The draw solutions used were magnesium chloride (MgCl2), aluminum sulphate (Al2 ( SO4)3 .18 H2O), feed reactive red, disperse blue dyes.Experimental work includes operating using thin film composite (TFC) membr...

Endometriosis is associated with pelvic pain and infertility, which affects approximately 10% of women of reproductive age. In recent years, Curcuma xanthorrhiza (CG) has been administered by some clinical practitioners to treat endometriosis and get satisfactory curative effects. The present study was then designed to investigate the effects of CG on the model rats with endometriosis. Forty fe...

In some livestock evaluation contests, participants will be required to place a performance class of breeding animals. A performance class is one in which two important pieces of information are provided to contestants: (1) a production scenario and (2) performance data. In some livestock evaluation contests, the scenario and performance data are used in conjunction with evaluating the phenotyp...

This work studies the effect of azobenzene dye Disperse Red 1 (DR1) doping and annealing on thermomechanical photomechanical properties poly(methyl methacrylate) (PMMA) fibers. The mechanical are measured as a function temperature, pump light intensity, polarization. We find that with DR1 increases stiffness glass transition temperature (Tg) PMMA Moreover, below Tg decreases Young’s modulus Tg....

Alors que la croissance de l’économie belge fut très soutenue durant une large partie l’année écoulée, nos estimations indiquent celle-ci a considérablement ralenti en fin d’année, comme le montre l’encadré 2. Les principaux facteurs explicatifs ce ralentissement sont dégradation situation sanitaire, les difficultés rencontrées par entreprises pour accroître leur production, et forte hausse l’i...
