This research was carried out to study the effect of ageing on antioxidant and biochemical changes of wheat (Triticum aestivum L.) seeds. The experiment laid out in completely randomized design (CRD) with four replications in Islamic Azad University, Boroujerd Branch, Boroujerd, Iran in 2015. The seeds of wheat (cv Sardari) were harvested at maturity and ageing treatments were done at 43° C wit...

www.thelancet.com Vol 374 October 3, 2009 1139 James W Vaupel’s career has always been about transcending the limits of his fi eld, demography. As the founding Director of the Max Planck Institute for Demographic Research in Rostock, Germany, Vaupel has helped to revolutionise the statistically bound fi eld by taking a multidisciplinary approach that incorporates both human and non-human biolog...

In abiotic degradation the action of light radiation is one of the most important parameters, because polymers undergo degradation due to the action of light (natural or artificial). The aim of this study was to investigate the degradation rate for samples of polypropylene (PP) modified with an organic pro-degradant submitted to ageing in a natural environment and to accelerated ageing test. Th...

objective: ageing of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. accelerated ageing has been recognized as a good predictor of the storability of seed lots. aged seeds show decreased vigor and produce weak seedlings that are unable to survive once reintroduced into a habitat. the characteristics of the chemical composition of...

The paper aims to examine the population ageing as a new phenomenon effecting rural areas in Iran. Population ageing is going up throughout the country especially in the rural areas by 6.8 percent. fertility decline, increase in the youth migration to cities, and coming back to rural areas after retiring are the major factors which involve in rural ageing. This may jeopardize the communities. f...

All cities are subject study. research covered period 2000-2020. categorised into small, medium, large, their specific characteristi...

Neuroendocrine tumors are most often located in the intestine and lungs but they can arise from other areas of the body. Limited data is available on epidemiology and clinical patterns of neuroendocrine tumors in Iran. We analyzed medical records of 34 patients from 2 cancer centers (Emam Khomeini hospital and Omid Charity Cancer Center) in west Azarbaijan province of Iran with neuroendocrine t...

the glass transition temperature (tg) and the melting temperature (tm) of gelatin at water contents between 7 and 14% were measured using differential scanning calorimetry.  the plasticisation of the polymer by water led to a decrease in tg and tm. the tg of partially crystalline gelatin was higher than that of the amorphous one obtained by quenching from the melt. the enthalpy relaxation occur...
