the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
to study the effect of different fertilizing systems on macro and micro nutrients uptake by annual medic (medicago scutellata cv. robinson) an experiment was conducted under dry farming and irrigated conditions at two research stations (sararood dryland agricultural research institute and soil fertility research station in mahidasht) during 2009 growing season. the experimental treatments consi...
The present study determined and compared contents of macro- (Nitrogen-N, Phosphorus-P, Potassium-K, Calcium-Ca, Magnesium-Mg) and micro- (Zinc-Zn, Iron-Fe, Manganese-Mn, Cupper-Cu) nutrients in four seagrass species big-leaved (BL) Halophila ovalis (R. Br.) Hook. f., small-leaved (SL) H. ovalis (R. Br.) Ascherson, H. spinulosa (R. Br.) Aschers. in Neumayer and Halodule uninervis (Forssk.) Asch...
In this study the effects of irrigation with raw or diluted municipal effluents along with foliar micro-nutrients fertilizer spray were examined on the growth, yield and mineral nutrient in foxtail millet plants. The experimental design was a split-plot with three irrigation sources (namely raw sewage, 50% diluted sewage and well water) as main-treatment and four combinations of Mn and Zn folia...

ارزیابی وضعیت تغذیهای چغندرقند با استفاده از روش DRIS و مقایسه آن با روشDOP در استان آذربایجان غربی
To establish DRIS norms in sugar beet (Beta Vulgaris L.) and compare them with DOP index, leaf samples were collected from 57 fields and N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B concentrations were determined. On the bases of crop yield, the fields were divided into two groups with low and high yielding performances. Standard DRIS norms were established for the different nutrient ratios. DRIS indi...
diagnosis and recommendation integrated system (dris) can be used as efficient methods to interpret the results of plant analysis and the nutritional diagnosis in crops and fruit trees. to establish dris norms in onion (allium cepa l) leaf samples were collected from 50 fields and n, p, k, ca, mg, fe, mn, zn, cu and b concentrations were determined. on the bases of yield, the studied fields wer...
background and objectives: multiple sclerosis (ms) is the most prevalent autoimmune disease of the central nervous system, and it has been suggested that nutrition might play a role in the etiology of ms. this study was aimed to evaluate the relationship between ms risk and intake of some macro- and micro-nutrients in tehran (iran). materials and methods: in this hospital based, case-control st...
