Iranian native hens are a valuable genetic resource, due to their adaptability to harsh conditions of husbandry and environment in rural area. The genetic parameters for various traits of economic importance were studied in an Iranian Native chicken population under short term selection for egg production and body weight for over 2 years. The parameters studied were body weight at day old (BW1)...

the genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. the results revealed that the single shell weight showed higher genetic variation such as pcv% (17.20%), gcv% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. the d2 (mahalonobis? distance) statistics revealed...

National Economic Input-Output (EIO) data describes the monetary transactions among economic sectors. The monetary transactions among these sectors form a weighted bi-directional network from a supply sector to a demand sector and the weight is equivalent to the transaction value between them. In this research, we study the properties of this network and identify patterns of inter-sector depend...

Th e aim of the study was to analyse the changes in BMI category between 7 and 16–18 years of age on the basis of continuous studies and evaluate which factors are related to the increase and decrease in BMI category. Data were collected from 1008 secondary school students aged 16–18 y. Body height and weight were measured and BMI was calculated. Information on height and body mass in earlier p...

The effect of fungicides on silkworm larvae was analyzed with regard to the fact that these beneficial insects are usually affected by fungicides, Daily feeding on 1 and 2g/liter of carbendazim, a systemic fungicide, did not have significant effects on larval and pupal mortality. However the weight of the treated larvae showed considerable weight decrease up to 37% weight.. All the economic tra...

in a case control study the effects of literacy, socio-economic status and the fertility behavior of mothers were fully investigated in two groups. out of 13123 babies born in 17 hospitals during almost 8 months in 1988-1989 in tehran 730 had a low birth weight (less than 2500 gr). as a control group, 1460 births were randomly selected from normal weight births. some basic findings are as follo...

Abstract Despite the significant rise in obesity in the U.S., economic research on obesity is still in its infancy. This paper employs a microeconomic approach to investigate the effects of price and income changes on weight in an effort to ...

BACKGROUND Self-reported weights and heights can be subject to gender, socio-economic, and other biases. On the other hand, obtaining measured anthropometric data can pose a significant respondent burden. METHODS Seattle Obesity Study II (SOS II) participants (n = 419) provided self-reported height, weight, and demographic data through an interviewer-assisted behavior survey. Participants wer...
