Abstract: Silk fibre is one type protein fibre and its coloration is also an art. Every types of natural dyestuff can be used for silk dyeing. Acid dyestuff used for silk dyeing and required more than boiling temperature, resulting fibre damage and more energy. In this research, coloured silk fabric with natural onion dye for textiles by using a method of dyeing that relies on natural ingredients extracted from onion’s outer shell colorant (Quercetin) by using water and organic solvents. And also used three types of mordants such as Alum, Copper Sulphate, and Potassium dichromate. The results of the research indicated that using onion’s outer shell, deeper and more stable shades of the colours were obtained in comparison with water and organic solvent extracts dyed silk fabric. All samples were better results obtained such as light fastness, rubbing, water, acid and alkaline perspiration, changes appear in a smaller extent.

Abstract: A total of 10 species of fungi belonging to 5 genera were isolated and identified from four cereal grains; wheat, barley, rice and maize collected from three Libyan cities known to grain producers (Al-Zawia, Subratah and Tripoli) on 1% dextrose-Czapkes agar medium at 28 ± 2°C for 7-15 days using seed-plate method. Two species of Alternaria (A. raphani and A. tenusinae); two species of Aspergillus (A. flavus and A. niger); three Fusarium (F. graminearum, F. moniliforme and F. solani); one Rhizopus species (Rhizopus stolonifer) and two species of Penicillium (P. digitatum and P. notatum) were isolated from the grains. The densities of these fungi and their frequencies of occurrence have been investigated. It can be concluded that for human public health, cereal grains of production chain must be subjected to quality control and microbiological examinations.

Abstract: Multi layers CdSe artificial atoms system prepared using Spin coating method. Using W-H method, which based on XRD Broading line profile, structural parameters of FTO/CdSe system were calculated. XRD spectrum reveal that CdSe nanoparticles have hexagonal structure, have high strain, show deposition layer on other do more stress and strain (Crystallization size (6.16 A◦), lattice constant C(7.16A◦), effective strain (0.07377 (lin–2 m–4)) between the nano crystals and dislocation (irregular) (26.443×1020 (lin–2 m–4)) were determined), which confirm more later by anther spectroscopic method. By doing fitting between experimental and theoretical absorption using Gaussian profile and Doppler broading line. Different electronic transitions were deduced and other broading curve were studying such as effect of particle size of artificial atoms, with doing more accurate fitting reveals existence of two intensities lines attributed to diffusion layer between FTO and CdSe artificial atoms.

Abstract: Abnormal passage of liquid or unformed stool at an increased frequency is termed as diarrhea: Infectious agents, certain medications, plant and animal toxins, gastrointestinal disorders, and substances that enhance gastrointestinal tract secretions are may be the triggers of diarrhea [1]. In recent times, medicinal plants occupy a considerable position for being the paramount sources of drug discovery irrespective of its categorized groups- herb, shrub or tree [2]. Oroxylum indicum (Linn.) Vent is widely used in Ayurvedic system of medicine [3]. The crude methanolic extract of Oroxylum indicum bark and fruits with different soluble partitionates were subjected to investigate for the evaluation of analgesic, hypoglycemic, CNS depressant and antidiarrheal activity on mice and thrombolytic, antihelmentic, antimicrobial, antioxidant along with cytotoxicity different in vivo experiment. [4] The antidiarrheal activity of methanolic bark and fruits extract and its different fractions of Oroxylum indicum (Ethyl acetate fraction, Dichloromethane fraction, Hexane fraction, Carbon tetrachloride fraction) (400mg/kg) cause reduction of diarrheal feces by 46.5%, 32.6%, 45.3%, 33.7%, 51.2%, respectively compared to standard Loperamide (82.6%). This reveals that methanol extracts of bark and fruits of Oroxylum indicum showed significant antidiarrheal activity.

Abstract: Advanced oxidation is one of the potential alternatives to decolorize and to reduce recalcitrant wastewater loads from textile dyeing and finishing effluents. This process implies generation and subsequent reaction of hydroxyl radicals, which are the most powerful oxidizing species after fluorine. Among AOPs, treatment with ozone (often combined with H2O2, UV, or both), an UV/H2O2 system, or Fenton and Photo-Fenton type processes have proven to yield very good results either for complete mineralization of reactive dyes or for their transformation into less complex structures that are more easily biodegradable. Particularly, we summarize recent researches in the AOP treatment using O3 alone and or in combination with UV, US and H2O2 of textile wastewater for complete color and COD removal and decrease the toxicity of the treated wastewater for water.
