any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
This study defined a wealth index that was strongly correlated with a health indicator: the survival of children aged less than five years. This index allowed the most vulnerable social groups for health outcomes to be identified. These groups could become the target for focused interventions and in particular for health-insurance schemes. The study was based on a thorough analysis of data coll...

in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
comparing non-mesh and sutured inguinal hernia repairs in groin surgery: a randomized clinical trial
purpose: mesh technique is the standard for inguinal hernia repair because of less recurrence, but it is inferior or equal to sutured technique in case of other post-operative complications such as chronic pain. this clinical trial set out to compare these two techniques. materials and methods: a total number of 322 cases of unilateral inguinal hernia in participants older than 18 years...
During a period of nine years (1982-1991), Pauwels' osteotomy was performed for 38 cases of femoral neck non-:::union:::. 32 led to consolidation with one osteotomy (84%) and 6 failed (3 needed revision (92%), one died and two were lost to follow-up). The length of follow-up was 2-11 years, the average time of non-:::union::: 12 months (ranging from 4 months to 13 years) and the mean patien...
background: acute upper gi bleeding (ugib) is a common medical emergency situation. in the past years, important changes have taken place that might have influenced the incidence, etiology, and outcome for patients with acute ugib. the aim of this study was to determine current time trends in the incidence, management, and prognosis of patients with ugib in 14 years period in a region in center...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
Background:Non-accidental poisoning in the paediatric age group is uncommon and international literature on this subject is limited. There are no Sri Lankan paediatric studies on non-accidental poisoning to date. The objective of the current study was to explore the predisposing factors and profile of children less than 12 years in rural Sri Lanka who had non-accidental poisoning. Method:This c...
