Zinc oxide nanoparticle thin films were synthesized on glass substrate by radio-frequency magnetron sputtering (RF Sputtering) technique. The thin films were characterized and tested for optical properties by using different techniques such as field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), UV–visible spectrophotometry and fluorescence spectrofluorophotometry. The produced nanoparticle ZnO thin films were investigated as photocatalyst for degradation of 2- chlorophenol (2-CP) in synthetic wastewater solutions under UV irradiation. Complete degradation of 2- CP was achieved by ZnO thin film (200 nm thickness) within 3 h at solution pH 3. The photocatalyst retained its high efficiency even after three reuse cycles.
Exact Solution of Klein Gordon Equation via Homotopy Perturbation Sumudu Transform Method
Sundas Rubab,Jamshaid Ahmad,Muhammad Naeem 보안공학연구지원센터 2014 International Journal of Hybrid Information Techno Vol.7 No.6
We apply the proposed method (NHPSTM) which is the combination of new homotopy perturbation methodand Sumudu transform to solve analytical linear and nonlinear Klein-Gordon equations. The proposed method finds the solution without any discretization or restrictive assumptions and avoids the round-off errors. The fact that the proposed technique solves nonlinear problems without using Adomian’s polynomials can be considered as a clear advantage of this new method over the decomposition method. Obtained results reveal that the proposed method is very efficient, simple and can be applied to other nonlinear problems arising in mathematical physics and engineering.

Cervical cancer is one of the leading causes of morbidity and mortality amongst the gynecological cancers worldwide, especially in developing countries. There are few to no initial symptoms and signs. This study was conducted to assess the awareness level of young Pakistani women about cervical cancer and to educate them about this deadly disease. A detailed questionnaire regarding demographic data and information about cervical cancer was distributed in different cities of Punjab. A total of 873 women took part in this survey and 70.1 percent were totally unaware of this cancer. Only 8.5% of the whole surveyed population knew accurately about cancer of cervix, 7% of the surveyed respondents correctly specified the human papilloma virus as the causative agent. Only 5.2% respondents were able to identify the Pap smear test as a diagnostic measure. Out of all the surveyed population only 4.3% of individuals were found to be vaccinated against this disease and the majority was found from the medical profession. Medical professionals, students, working women, housewives and uneducated individuals took active part in this survey. This study demonstrates a low level of awareness among Pakistani women and a need for an active campaign by media and government to increase understanding as well as introducing measures for improved prevention and treatment of cervical cancer.

Multidrug resistance of bacteria is an emerging human health hazard and warrants development of novel antibacterial agents with more effective mode of action. Here, zinc oxide and silver nanomaterials were prepared using Ficus palmata Forssk leaf extract with efficient antibacterial activity. SEM coupled with EDS confirmed the spherical symmetry with average particle diameter 50 to 65 nm while the XRD confirmed crystalline face centered cubic structure of silver and hexagonal crystallize phase of zinc oxide nanoparticles. Antibacterial activity was evaluated for 8 pathogenic bacterial strains including 3 drug resistant pathogenic strains. The nanoparticles showed enhanced growth inhibition for resistant strains in comparison with the broad-spectrum antibiotics i.e. roxithromycin and cefixime. Minimum inhibitory concentration in μg.mL<SUP>-1</SUP> of silver nanoparticles was found to be as low as 33.3 for resistant Streptococcus haemolyticus; 11.1 for Staphylococcus aureus and E Coli; and 3.7 μg.mL<SUP>-1</SUP> for resistant Pseudomonas aeruginosa. Similarly, the minimum inhibitory concentration of zinc oxide nanoparticles was found to be 100 μg.mL<SUP>-1</SUP> against resistant Streptococcus haemolyticus and Staphylococcus aureus; 11.1 μg.mL<SUP>-1</SUP> for resistant Pseudomonas aeruginosa; and 3.7 μg.mL<SUP>-1</SUP> against resistant E coli. Ficus palmata Forssk leaf extracts can be explored effectively for synthesizing active antibacterial nanomaterials as a non-toxic and environmentally benign synthesis route.

Investigations on influence of stitch types in single jersey knitted fabric on flammability and comfort properties arecarried out in this paper. Seven different knitted structures were developed on single jersey machine. In this study the effect ofcombinations of knit, miss and tuck stitches on comfort and flammability properties of knitted fabrics are investigated. Flammability test/properties e.g. afterglow time, char length, and weight loss % are evaluated. Several tests for thermophysiologicalcomfort i.e. air permeability, thermal resistance and absorbency are also carried out. Results obtained show thatboth comfort and flammability properties are dependent on type of stitch, pattern of stitch, location of stitch and percentage ofany stitch used in the fabrics. Moreover, fabric physical parameters also affect the flammability and comfort properties. Thefindings of this study shall work as a guide for material or textile engineers in the design and selection of fabric for apparel aswell as high performance thermal protective clothing; as a result safety and occupational health of fire fighters will beimproved.

The main aim of this study is to determine the thermo-physiological comfort properties of single knit fabrics and their derivatives. As the Single Jersey knitted fabrics are the most widely used fabrics in the apparel sector, they have been selected for the analysis purpose. Derivatives of single jersey are developed and compared in order to understand the infuence of structural variations. Physical properties e.g. thickness and areal density were evaluated for all knitted fabrics with 100% cotton yarn having three diferent yarn linear densities and after diferent stages of relaxation. Various thermo-physiological properties have been studied by changing the combed cotton yarn linear density as well as the structure of single knit fabric. Air permeability, thermal insulation and relative water vapor permeability of the fabrics were observed and investigated under wet relaxed states. It is determined that fabric physical properties are afected by changing yarn linear density and by the dry or wet relaxation stages. The percentage/number of tuck stitches (NTS), location of tuck stitches (LTS) and ratio of tuck to knit stitches (RTKS) have strong infuence on physical and thermo-physiological properties of single knit fabrics, even though other knitting parameters remained the same.
