Creative thinking skills plays a paramount role in child’s developments. It is the heart and soul of child's education. It is the foundation on which the personality of child is built. The study of mother-tongue is of dire necessity on the aforementioned skills. Teachers rarely use teaching technology like multimedia, instructional technology etc. They adopt lecture cum text book method-a boring procedure. No attempt is made to arouse their creativeness or encourage their self-expression so what they learn is poor learning. The researcher takes the initiative to bridge the relationship between the utilisation of technological methods in Arabic classes and the enhancement of critical thinking skills as a result of adopting technological methods.

In this paper, we explore different notions of sets namely ?-open , semi-open , pre-open , b-open and ?-open to define the concept of delta-convergence and delta-adherence of grills in a topological space. Further, we discuss their characterizations

Deployment of maintenance and quality management systems comprehensively (TPM and TQM) have an important role in improving the productivity of manufacturing industries. Results of studies confirmed that implementation of TPM and TQM systems in many industries have not been successful. This research evaluated TPM and TQM deployment readiness in the Iranian prominent automaker, Pars Khodro, by appointing three different enablers. Research findings indicate that General and TPM enablers in Pars khodro are desirable, while TQM enablers should be boost.

The concept of system lifecycle models came into existence that emphasized on the need to follow some structured approach towards building new or improved system. Many models were suggested like waterfall, prototype, rapid application development, V-shaped, top & Bottom model etc. In this paper, we approach towards the traditional as well as recent software development life cycle models.

Cryogenic homogenized cotton samples were tested for mercury traces with very low concentrations we used analysis technique namely Cold Vapor/ Isotope Dilution ICP-MS. Target element is listed in Öko-Tex Standards and it should be absent or less than 0.02 mg/kg in the tested cotton samples for baby, direct skin contact and decoration products. Due to the presence of Hg in a very low concentration we need to measure it with high accuracy and low uncertainty sources testing method. In this work a previously homogenized Egyptian cotton samples were tested for total content of mercury. These samples included cotton varieties represent extra long staple (Giza 70 and 88) and long staple (Giza 89). The measurements were made using isotope dilution cold vapor inductively coupled plasma- mass spectrometry (ID-CV-ICP-MS) with Carius tube digestion. The results showed that the tested homogenized cotton samples have very low concentrations that cannot be detected by many other mercury analysis techniques. Uncertainty budgets also estimated in this work for all samples.

This study was aimed at assessing the concentrations of heavy metals and other elements in surface dust at Agbogbloshie, where crude methods are used for e-waste processing. Dust samples were collected from fourteen locations within Agbogbloshie including the dismantling site and burning site of the scrap market. The X-ray fluorescence spectroscopy (XRF) was used to evaluate the concentrations of the heavy metals and other elements in the samples. Heavy metals such as Zn, Cu and Pb gave concentrations in the range of (422.54 – 181752.94mg/kg), (101.83 – 9144.50mg/kg) and (117.03 – 14448.46mg/kg). All these concentrations and that of most elements exceeded the New Dutch List Action Values (for which intervention is required) over thousand times. The road surface, dismantling site, burning site and the Domod office recorded very high concentrations of heavy metals. The Ayalolo cluster of schools also gave alarming concentrations of heavy metals. Assessment of human heath risk of these heavy metals indicated that, exposure to dust through dermal contact posed the highest health risk to children under 6 years. Hg was the only element which indicated a higher risk through the inhalation of vapour. The hazard indices (HI) computed indicated that the values from all the sites were above the safe level of one. The dismantling site gave the highest HI value of 882.57 for Pb from all the sites. Further research work on health risk assessment should be conducted for those directly involved in the recycling activities.
