This study examines the pressures which lead to employers offering low-paid, insecure jobs and also considers the scope for change. Employers determine terms and conditions and how work is organised, including pay, the balance between temporary and permanent work, skill requirements and progression structures. In seeking to reduce intermittent poverty, it is, therefore, important to consider ho...
Vapor-liquid equilibrium in NH3-CO2-H2O system at high pressures has been studied. The UNIQUAC-NRF model for this system was extended by using the Goppert 4 maurer reported datas. Since the system contains molecules and ionic species the binary interaction parameters considered, where those are of molecule-molecule, molecule-ion and ion-ion types. These interaction parameters are taken as c...
In this work the effects of heat generation on the modes of Yb:Glass double clad fiber laser were investigated. The thermal dispersion and thermally-induced birefringence were considered when the gain medium becomes an anisotropic medium. The results showed considerable modifications of laser modes profiles, in particular for transfer magnetic (TM) and transfer electric (TE) modes which their p...
a refrigeration cycle is a chain of various pieces of equipment including compressors, condensers, evaporators, and expansion devices each of which takes on a particular thermodynamic process duty in the cycle that eventually results in the production of the required refrigeration. the results of optimized mixed refrigerant cycles (mrcs) in part i show that the configuration of mrc is an effect...
toxicity bioassays are important tools to determine biological effects of chemical agents on species. the questions remained on, what effects have been imposed on each of the different molecular site of cells by chemical exposure and how to find a pattern for chemical toxicity. to address the questions, hepg2 cell lines were exposed to the different concentrations of cisplatin for 24 hours to r...
Self-organized patterns of cathodic spots have been observed in microdischarges operated in xenon, but not in other gases. However, modelling has indicated that it is, in principle, possible to observe the patterns of spots in discharges operated in other gases provided that experimental conditions, in particular pressure, are right. In this work, self-organized patterns of cathodic spots are f...
The importance of peer-review in the scientific process can not be overestimated. Yet, due to increasing pressures of research and exponentially growing number of publications the task faced by the referees becomes ever more difficult. We discuss here a few possible improvements that would enable more efficient review of the scientific literature, using the growing Internet connectivity. In par...
In the current work we describe the development of an oxygen plasma-free microfluidic device sealing method with tunable properties. In particular, it allows the end-user to bond PDMS-glass microfluidic devices using nothing more than some mild acidic buffer, and access to an oven, and achieve burst pressures of more than 80 psi, or 0.55 MPa. The minimal requirements on the processing steps mak...
