Partially clonal organisms are very common in nature, yet the influence of partial asexuality on the temporal dynamics of genetic diversity remains poorly understood. Our results argue for a dynamical interpretation of FIS in clonal populations. Negative values cannot be interpreted as unequivocal evidence for extremely scarce sex but also as intermediate rates of clonality in finite populations.

The age-stage, two-sex life table method was used for data analysis. The results indicated that EPF treatments affected the population growth rate of the aphids by causing prolongation of the development time, decrease in survival rate, shortening of adult longevity, and decrease in reproduction. The intrinsic rate of increase (r) and the finite rate of increase (λ) reflecting combined effects of all life history parameters were the highest in the control group and the lowest in M.

The predator-prey model is an essential tool in mathematical ecology and specifically for our understanding of interacting populations in the natural environment. We consider a predatorprey model with variable carrying capacity and cross-diffusion. First, we recall some recent results on the existence and regularity of inertial manifolds for nonautonomous evolution equations involving sectorial operators.

Minimal available information concerning hip morphology is the motivation for several researchers to study the difference between Asian and Western populations. Current use of a universal hip stem of variable size is not the best option for all femur types.

Cancer patients are likely to undergo osteoporosis as consequence of hormone manipulation and/or chemotherapy. Little is known about possible increased risk of fracture in this population. The aim of this study was to describe the biomechanical effect of a metastatic lesion in an osteoporotic lumbar spine model.

Disease progression models are important for understanding the critical steps during the development of diseases. The models are imbedded in a statistical framework to deal with random variations due to biology and the sampling process when observing only a finite population.

In the present study, we have developed new estimators for the estimation of finite population variance by using auxiliary information as combination of conventional and non-conventional measures. Bias and mean square error has been worked out up to the first order of approximation. The empirical study has been carried out through numerical demonstration, under which improved estimators have performed better than the other existing estimators.

In order to know the degree of relevance or significant contribution of this practice bank in the learning of autonomous photovoltaic solar systems, a questionnaire was applied - a survey of a finite population of 25 students who had taken the subject of Alternative Energies in the period 2019- 1, from the Santo Tomás University, Tunja. The results obtained allowed us to determine that all students agree that this laboratory equipment is relevant and meaningful for their learning, so that the theoretical knowledge obtained in class is complemented by laboratory practice.

In the present paper, an attempt has been made to conduct a limited simulation study to examine the relative performance of calibration approach based estimators. The real data has been taken from Appendix-C of Sarndal et al., (2003). The study variate y and the auxiliary variate x are the population of the Sweden in year 1985 and year 1975 which is divided in 284 municipalities (MU284). The results have been found that the calibration estimators have outperformed the usual estimator of finite population mean in two-stage stratified random sampling.

The purpose of this research is to analyse the attitudes and believes of Irish investors towards green and ethical investments. Why they invest in green, is it profit maximisation or ethical considerations and what are the barriers for green investments. How feasible is the government policy and targets set for greening the Irish economy by 2020.

(bq) the book contains about 350 well placed and instructive problems, which cover a considerable part of the subject. all in all this is an excellent work, of equally high value for both student and teacher. the book continues to exert its influence sixty years after publication, as linear algebra is now widely used, not only in mathematics but also in the natural and social sciences, for studying such subjects as weather problems, traffic flow, electronic circuits, and population genetics.

Given that social media applications and services have only recently become available, these high usage rates indicate a surprisingly rapid take up among large parts of the European population. These findings are confirmed by a recent IPTS assessment of social computing (Ala-Mutka et al. 2009b) and by figures from other independent sources. Nielsen Online (2009) estimates that, globally, 67% of Internet users accessed social networking sites or blogs in 2008.

The population exposure without PM10 fraction attributable to road traffic is shown in Figure 6. Compared to total PM10, the frequency distribution changes considerably. Most people would live in areas with PM10 values less than 20 µg/m3. In France and Switzerland, less than 3% of the population would live in areas with PM10 greater than 20 µg/m3. In Austria, this portion is higher due to an increased non-traffic caused regional PM10 background.

In January 2009 WWF-UK launched its One Planet Food programme, which aims to reduce the environmental and social impacts of food consumption in the UK. We work across the food chain to reduce greenhouse gas emissions (GHGEs), protect biodiversity and reduce the impact of food on finite water resources. The aim has always been to move away from unsustainable food choices, towards sustainable ones that support global agriculture and biodiversity. Since 1960 the world’s population has doubled, increasing the demand for food and impacting on the climate and our ecosystems.

Malaria risk exists in Myanmar throughout the year: 29% of the population live in high risk areas, 24% in moderate risk areas and 18% in low risk areas. Apart from those living in endemic areas, a major risk group are non-immune adult migrants in forest areas who work in gem mining, logging, agriculture, plantations and construction. The full extent of the burden of malarial disease is likely to be higher than records indicate due to a poor reporting system. The disease is endemic in 284 townships out of 324. One hundred of these townships account for 53% of the...
