Abstract Corn ( Zea mays L.) provides a major source of calories for human consumption and therefore, the nutritional components corn have large impact on health. For example, kernels contain antioxidants, such as polyphenols (including anthocyanins other flavonoids) carotenoids. Such compounds represent useful targets biofortification breeding. In this study, we used 34 inbred lines from three...
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
objective: fusarium diseases that cause grain mold and stalk rot of millet are the most important diseases, of these crops in iran. fusarium can cause stalk rots, ear rots, and grain mold, resulting in serious production losses in millet, and produce mycotoxins that are harmful to both humans and domesticated animals. methods: a total of 23 fusarium isolates were recovered from foxtail millet ...
background: one of the most critical problems in the field of water and food pollution is the heavy metal pollution. agricultural products are exposed to this type of contamination through wastewater; industrial activity and population pollutions are also in its area. since the plant in the affected areas can directly enter heavy metals into the food chain, so, it is important to check their le...
the purpose of the present study is to find out whether bilinguals of khuzestan-arab origin or monolinguals of iranian origin code-switch during learning or speaking english and which group is more susceptible to code-switch. to this end, the students of 24 classes from high schools and pre- university centers were screened out, and interviewed and their voices and code-switchings were recorded...
rhizoctonia zeae causes root rot and sheath blight on corn (zea mays) and several other gramineous plants. in order to determine the genetic diversity of the r. zeae population in mazandaran and golestan provinces, samples were collected from cultivatd soils of both provinces in 2011 and 2012.the identity of isolates as r. zeae were verified by amplification and sequencing of the 18s and 28s rd...
abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
Wide variations in the prevalence of asthma, allergic rhinitis and eczema have been reported in the world, between regions and countries. The international study of asthma and allergies in childhood (ISAAC) was developed to provide standardized method to ascertain the prevalence of asthma and allergies in different regions. Comparisons of prevalence rates across geographic regions may help to i...
