Developed countries are interested in the retired segment and provide them with many services such as medical care, housing entertainment, whether it is between his family or homes of elderly, discrepancy world retirement age, but Iraq a large number referred to when they reach civil legal age (60 years). Al-Askari (50 years) has service no less than (15 years), noted that residents increased y...
Using computer tapes of death registrations for the period 1980-2, and paper copy of population data for the 1981 census, death rates were calculated for the population resident in each of the 112 postcode sectors that make up the area served by the Greater Glasgow Health Board. Rates were calculated for both sexes in combination for each of the age groups 60-64, 65-69, 70-74, 75-79, 80-84, and...
Population Balance Modelling of Zirconia Nanoparticles in Supercritical Water Hydrothermal Synthesis
Like any other precipitation process, in supercritical water hydrothermal synthesis (SWHS), the need to improve product quality and minimize production cost requires understanding and optimization of Particle Size Distribution (PSD). In this work, using Population Balance Equation (PBE) containing nucleation and growth terms, the reactive precipitation of zirconia nanoparticles prepared by ...
according to the classical economists such as ricardo, labour was considered as the only factor of production; while capital, realized in machinery, tools and the like was identified as the accumulated labour and that inferior lands can be exploited due to the use of labour on them. but, in the long run development of capitalism in the western countries, this idea, i.e. labour as the base of pr...
An investigation of the population parameters of Indian mackerel, Rastrelliger kanagurta (Cuvier, 1816) in the Marudu Bay, Sabah, Malaysia was carried out from January to September 2013. The relationship between total length and body weight was estimated as W=0.006TL3.215 or Log W=3.215LogTL – 2.22 (R2=0.946). Monthly length frequency data of R. kanagurta were analyzed by FiSAT software to eva...

Causes of interspecific variation in growth rates within and among geographic regions remain poorly understood. Passerine birds represent an intriguing case because differing theories yield the possibility of an antagonistic interaction between nest predation risk and food delivery rates on evolution of growth rates. We test this possibility among 64 Passerine species studied on three continent...
This study was conducted to collect comprehensive identification about Markhoz goat population and to simulate past dynamics of the population under its living conditions.Census data of the population size and the required parametersfor the simulation modelwere obtained frompublished data or were collected in its habitat in the last 3 years. In this study, past population dynamics and expected ...
Aquatic environments are often received to industrial, agriculture and domestic effluents containing metals and caused biological problems for microalgae because they require to some of essential trace elements. In this research, solely effects of different concentrations of Zn (450, 900 and 1350 mg/l) and Mn (75, 150 and 225 mg/l), and their combined effects (450+75, 900+150, and 1350+225 from...
