In experiment 1 NoSo and NoS pi thresholds for a 500-Hz pure tone were obtained in a low-fluctuation masking noise and a high-fluctuation masking noise for six normal-hearing listeners. The noise bandwidth was 10 Hz. In agreement with previous investigations, the NoSo thresholds were lower in low-fluctuation noise than in high-fluctuation noise. For three listeners, NoS pi thresholds were simil...

Background The reduction in fertility and increase in the number of single-child families in Iran will result in an increased risk of population aging. One of the factors affecting fertility is women's empowerment. This study aimed to evaluate the relationship between women's empowerment and fertility in single-child and multi-child families. Materials and Methods This case-control study was ...

IN ISOLATED populations underdominance leads to bistable evolutionary dynamics: below a certain mutant allele frequency the wildtype succeeds. Above this point, the potentially underdominant mutant allele fixes. In subdivided populations with gene flow there can be stable states with coexistence of wildtypes and mutants: polymorphism can be maintained because of a migration-selection equilibriu...

curly top disease is one of the important diseases of sugar beet. spatial pattern and population variation of leafhoppers circulifer haematoceps, and c. tenellus, vectors of sugar beet curly top virus, were studied in hamadan province, iran for three years (2007- 2009). sampling was carried out at the early stage of the plant growth, in accordance with planting date for 9 weeks, in 7- 10 day in...

Abstract Visual cortical responses are known to be highly variable across trials within an experimental session. However, the long-term stability of visual is poorly understood. Here using chronic imaging V1 in mice we show that neural repeated natural movie clips unstable weeks. Individual neuronal consist sparse episodic activity which stable time but gain Further, find individual episode, in...

year among a certain number of livinginhabitants of a community or state. Of it is usual to calculate this proportion per 1,000 inhabitants. The birth-figure and the death-figure are of opposite significance in estimating the movement of a population. The smaller the birth-figure and the larger the death-figure> the more favourable is it for development, as then the increase by the births occur...
