BACKGROUND The Food Frequency Questionnaire (FFQ) is the most commonly used method for ranking individuals based on long term food intake in large epidemiological studies. The validation of an FFQ for specific populations is essential as food consumption is culture dependent. The aim of this study was to develop a Semi-quantitative Food Frequency Questionnaire (SFFQ) and evaluate its validity a...

one of the method to clean up contaminated soil is growing a hyper accumulator plant which is named phytoremediation. some of  hyper accumulator plants are proper host for mycorrhizal fungi.in this relationship, fungus, consume a part of organic carbon from the plant and by developing its mycelium network help plant to uptake more mineral nutrients from the soil. by doing a greenhouse research ...

this study was conducted to choose the best species for plantation on a poor drainage soil in southern coast of caspian sea, iran. nutrient concentrations in live and senescent leaves and soil properties were compared among alnus subcordata c.a.mey (n-fixing tree), populus deltoides­ marsh. (non n-fixing tree)and taxodium distichum (l.) rich. (coniferous tree) plantations. in each of these plan...

ABSTRACT: Fertigation is widely used in seedling production for different crops, including passion fruit. There no consensus on the ideal nutrient solution, and as such, nurseries have fertigation empirically. This study assessed electrical conductivity of solution containing macro micronutrients fruit compared it with commercially fertigation. A completely randomized design was used, five trea...

abstract pistachio ( pistacia vera l.) is an important crop in our country and has a unique position in export goods. in respect to better nut quality this research was conducted during 2005-2006. macro and micronutrients were used as foliar application to surmount soil limitations in nutrient uptake and alternate bearing control with “owhadi” cultivar in rcbd with 3 replications. the treatment...

Studies on the effect of simulated acid raid rain (pH 2.0, 3.0, 4.0, 5.0 and control pH 5.6) growth, yield mineral nutrient relations Capsicum frutescens (chilli pepper) was carried out. Simulated (SAR) prepared by adding sulphuric nitric in ratio 3:1 to distilled water get desired pH, sprayed plants. The experimental result indicated that under stress rain, growth parameters which include plan...

We present a T E X macro package for generating the arabic writing from a standardized ASCII input notation. It can handle partial or full vocalization, and generates automatically most of the common ligatures. There is limited support for Farsi, Urdu, and Pashto. ArabT E X is compatible with Plain T E X and also most L a T E X environments; arabic and other material can be mixed freely. For sp...
