The metal complexes of Mn (II), Co (II) and Ni (II), were prepared by mixing and refluxing methanolic solutions of MnCl2, CoCl2 and NiCl2 with N-[4- (Phenyliminomethyl)phenyl]acetamide 0.67-hydrate. Metal Schiff base complexes were prepared and characterized by using different techniques, such as; infrared and atomic absorption spectroscopy. Octahedral geometry was proposed for synthesized metal complexes by comparing theoretical and estimated metal ligand ratio. All the synthesized compounds were tested for their antibacterial activity against Staphylococcus epidermidis, Escherichia coli and Staphylococcus aureus bacteria. Schiff base itself was inactive against these bacteria whereas its complexes with Mn (II), Co (II) and Ni (II) have remarkable action against these bacteria, indicating that they can be used as bactericidal agents.

Sawdust carbon (SDC) and chemically treated sawdust carbon (CSDC) were characterized using SEM, FTIR. The effect of variables like pH, contact time, initial Ni (II) concentration, sorbent dose and temperature were studied. Maximum % uptake of Ni (II) ion (86.50 %) was achieved at pH 7. The maximum Ni (II) removed from aqueous solution in 70 min after the starting of each experiment. The batch adsorption kinetic studies have been carried out and the applicability of the Freundlich and Langmuir adsorption isotherms were conducted at room temperature for the Ni (II) in aqueous system. The adsorption data fit well in Langmuir adsorption model. The pseudo-first-order, pseudo-second-order, intraparticle diffusion and Elovich models were tested for kinetic study. The data shows that pseudo-second-order model (R2 > 0.99) was the best choice among the kinetic models for description of adsorption of Ni (II) on CSDC. The spontaneous and endothermic nature of the sorption process was revealed from thermodynamic parameters such as standard entropy, free energy and enthalpy. The effect of some common alkali and alkaline earth metal ions were also studied which showed that the presence of these ions have no effect on the sorption of Ni (II). The results showed that CSDC has the potential to be used as a low cost sorbent for the removal of Ni (II) from aqueous solutions.

The formation of pills occurs as a consequence of mechanical action during washing or wear. Pilling of fabric changes its aesthetic properties. Pilling prevention is an ongoing challenge for manufacturers of cotton, polyester and blended fabrics. For the textile finishers, there are many methods for reducing the pilling tendency of the Fabric. One of them is the application of Anti Pilling Finishes. In this method Fabrics are treated with special anti pilling agents to prevent pilling that promote adhesion of the fibres in the yarn or the fabric. This paper endeavors to optimize the application of different anti pilling agents at different concentration and pH levels on the P/C fabric for superlative results. The results revealed that different anti pilling finishes have significant effects on the fabric pilling at different concentration level however different pH levels have no considerable effects.

Limestone and clay of the area under investigation have been utilized in the raw mix designing and clinkerization of white cement. The physical and chemical parameters of resulting cement have been studied and compared with British and Pakistan standard specifications, including compressive strength, setting time, consistency, lechatelier expansion, Blaine and insoluble residue. Three samples of white cement were manufactured by mixing limestone samples in different proportion obtained from different locations of the study area. All the three cement samples were found with close agreement with British and Pakistan standard specification. It was found that the raw material available at the study area meets the standard specifications and the area is feasible for the cement plant installation. The raw material available at the study area is quite sufficient for the running of cement plant. Thu, 09 Feb 2012 00:00:00 GMT http://localhost:80/xmlui/handle/123456789/20064 2012-02-09T00:00:00Z
