Chenopodium album L. ssp. album is a common plant species worldwide, especially in humid areas. Sun exposure after oral intake of the plant can lead to sunburn-like rashes owing to its furocoumarin content. In this article, we reported nine patients who developed dermatitis with edema, erythema and necrosis on the face and dorsum of the hands. Each was exposed to sunlight after eating selemez (...
Background: The use of allelopathic plant extracts as herbicide is being popularized in recent years. Objective: This research has been conducted to evaluate the allelopathic potential of caltrop (Tribulus terrestris L.) on seed germination and growth of Avena fatua L., Chenopodium album L., Setaria viridis L. and Amaranthus retroflexus L. Methods: This research was done to evalature the ef...
Despite an extensive history of research into herbicide resistance in New Zealand maize, some aspects remain understudied. Herbicide was first detected the 1980s maize crops, with atrazine Chenopodium album L. and Persicaria maculosa Gray. Since then, has also developed to dicamba, last five years Digitaria sanguinalis (L.) Scop. populations have been reported be resistant nicosulfuron. Here we...
recent years have witnessed an increased attention to form focused instruction and consciousness raising activities (ellis, 2002; doughty & williams, 1998) on the one hand and extensive and meaningful exposure to the target language (klapper & rees, 2003; day & bamford, 1998) on the other. due to significance attributed to above mentioned issues by scholars, this study attempted to bridge them ...
The Chenopodium genus comprises ~150 species, including Chenopodium quinoa and Chenopodium album, two important crops with high nutritional value. To elucidate the phylogenetic relationship between the two species, the complete chloroplast (cp) genomes of these species were obtained by next generation sequencing. We performed comparative analysis of the sequences and, using InDel markers, infer...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
A study was carried out to determine the composition and predominance of weed species in wheat field in Khokana of Kathmandu valley as a representative sample of mountain ecosystem in Nepal. A total of 44 weed species representing 18 families were recorded. The most abundant species were Chenopodium album, Polygonum plebeium and Spergula arvensis. With the improved temperature after February, t...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...
in order to examine the multi-species weed competition in corn field an experiment as an interval mapping was carried out at the agricultural research field of ferdowsi university of mashhad during growing season 2009-2010. at 3-4 leafy stages of corn, 20 non-destructive quadrates determine and the density of weeds was counted separately. at the same time, 20 destructive quadrates determine and...
