The rate of complying for ISO 14001 Environmental Management Systems (EMS) certification has been generally slow in Sri Lankan Organizations compared to the adoption of other popular management systems certifications like ISO 9001 Quality Management System and ISO 22000 Food Safety Management System. Further, the awareness on the benefits of having this certification for an organization is also at very low level. The present study is focusing to get some research data on the potential drivers that could be used to adopt ISO 14001.

When the size of materials and structures shrinks to nanometer, the influence of surface energy on their stress field becomes more important in nanoscale due to their relatively high surface-to-volume ratios compared to that of a macro-scale domain. Based on Gurtin-Murdoch surface elasticity theory, displacement potentials are used to solve the three dimensional boundary-value problems involving non-classical boundary conditions represented by the generalized Young-Laplace equations.

The name Terry originated from the way towels were manufactured originally. The towels are manufactured by compiling loops and then pulling them out to form a textile product. Historically, these loops were pulled out by hand and thus named from a French word “Tire” which means to pull out. Thus,A Terry towels may be described as a textile product which is made up with loops on one side or both side of the cloth. The loops enable the towels to absorb a large amount of water. These towels can be manufactured by weaving or knitting.

Now a days demand for smart home devices are increasing with a rapid pace. Portable Knock Detecting Notifier(PKDN) is a small wireless device that instantly transforms ordinary surfaces (walls, tables, doors, furniture, countertops, & more) into a powerful touchpad. This is a very unique approach to control home devices as well as send alert notification to the user .Our device (PKDN) uses home Wi-Fi network to connect to other devices and is programmed to accept various commands through number of knocks.

Welding of dissimilar aluminum alloys (AA) is not reliable by using fusion welding techniques. Many fusion defects such as porosity and hot crack have been observed by these techniques due to the melting of these alloys. It can eliminate the fusion defects by using a different process technique to join these alloys without melting. One of this processes is friction stir welding. This process is a solid state joining technique which joins metals under its melting temperatures. This process uses a tool which consists a shoulder to produce heat by friction and a pin to stir the welded metals.

Currently there is a growing interest in researching and developing new antibacterial agents from various sources to combat bacterial resistance. Therefore, a greater attention must be paid to antibacterial activity screening and evaluating methods. Several bioassays such as disk-diffusion, well diffusion and broth or agar dilution are well known and commonly used, but other methods are not widely used because they need some special equipment.

Introduction: Urothelial carcinoma (UC) is the most common type of bladder cancer (BC). Approximately 75% of all BCs are restricted to the mucosa. Ten to 30% of superficial tumors will progress to invasive disease with worse prognosis. The epithelial to mesenchymal transition (EMT) is associated with the acquisition of tumor invasiveness and aggressive phenotypes. E-cadherin (E-CA) and vimentin are two proteins related to the EMT phenomenon.

The proposed RP-HPLC method is developed and subsequently validated which is rapid, sensitive and reproducible for the analysis of amikacin in pharmaceutical dosage forms with short analysis time. A mobile phase is a mixture of acetonitrile, methyl alcohol, and o- phosphoric acid, OPA, (0.1%) in 50:35:15 (v/v).A flow rate of 1.0 mL/min mobile phase was found to be suitable in the studied range of 0.5—1.5 mL/min. The spectra of Amikacin showed a balanced wavelength at 272 nm.

In this paper, a study of phase diagram of a binary mixture of two compounds of liquid crystal has been produced by high resolution temperature scanning technique. Heptyloxy cyanobiphenyl (7OCB) and octyl cyanobiphenyl (8CB) has been chosen to produce binary mixtures. The former compound exhibits only nematic phase so that it is treated as nematogenic and the latter is smectogenic which exhibits both nematic and smectic phases. Binary mixtures of these compounds in a certain concentration range (0.1 < x7OCB < 0.90 except 0.8) has been reported here.

Background: Malaria is a major public health problem in Ethiopia. Somali Region is one of malaria endemic areas in the country. It’s known that the use of Insecticide Treated Nets (ITNs) is one of most important malaria preventive methods. However, there are no studies concerning ITNs utilization and factors associated with its utilization in Gode district. The objective of the study is to assess the ITNs coverage, utilization and associated factors at household (HH) level in Gode District, Somali Region, Gode zone, Eastern Ethiopia.
