the use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. one of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. this research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...

the seeds of lepidium sativum (garden cress) were selected as a new source of hydrocolloid and some of its fundamental physico-chemical properties such as intrinsic viscosity and functional group were determined. ftir analysis showed that this polymer was composed of carbohydrate with functional carboxyl and hydroxyl groups. intrinsic viscosity was determined to be 1.33 ml/mg in water. the hydr...

The chemical composition of the essential oils of S. hierosolymitana Boiss. and S. multicaulis Vahl. var. simplicifolia Boiss. collected in Lebanon was studied by means of GC and GC-MS analysis. In all 115 compounds were identified: 82 for S hierosolymitana and 72 for S. multicaulis var. simplicifolia. The presence of carbonylic compounds (17%) characterizes the oil from S. hierosolymitana,whil...

The study was conducted to evaluate metabolic answer of Lepidium sativum L. on Hg, compost, and citric acid during assisted phytoextraction. The chlorophyll a and b contents, total carotenoids, and activity of peroxidase were determined in plants exposed to Hg and soil amendments. Hg accumulation in plant shoots was also investigated. The pot experiments were provided in soil artificially conta...

We analyze how temporal variability in local demography and dispersal combine to affect the rate of spread of an invading species. Our model combines state-structured local demography (specified by an integral or matrix projection model) with general dispersal distributions that may depend on the state of the individual or its parent. It allows very general patterns of stationary temporal varia...

Lepidium sativum Linn. has been used in traditional and folklore medicine for the treatment of bronchial asthma, diabetes, local and rheumatic pain. The present study deals with the investigation of the neurobehavioral effects of the total alkaloid from seeds of Lepidium sativum [LSAF].The effect of LSAF on general pharmacology, thiopental induced hypnosis, locomotor activity, motor coordinatio...

Sexual selection favors strategies that enhance the fertilization chances of sperm donors, and sexual conflict can ensue when these adaptations negatively affect sperm recipients (Arnqvist and Rowe 2005). Such conflict often causes counteradaptive coevolution that can result in bizarre mating behaviors in separate-sex (Arnqvist and Rowe 2005) and hermaphroditic species (Michiels and Newman 1998...

Garden cress or "hab arachad" seeds are considered one of the popular medicinal herbs used in Arabian countries. Garden cress meal (Lepidium sativum) is a by-product remaining after the extraction of the oil from seeds. The decline in male reproductive health and fertility in the last 30 years has been linked to environmental toxicants. The present study was designed to investigate the effects ...
