Background: The increasing demand for using mobile phones has led to increasing mobile phone jammers as well. On the other hand, reports show that exposure to electromagnetic field causes an increase in the incidence of diseases such as leukemia, cancer, depression and failure in pregnancy outcomes; therefore, the aim of this study is to investigate the effects of exposure to electromagnetic fi...

Since the mid-1980s, watermelon fields in southwestern Indiana have experienced outbreaks of a disease syndrome known as mature watermelon vine decline (originally known as sudden wilt). The disease was a limiting factor in production and reduced yields in many fields in 1989, 1995, and 1999. In 2000, it was especially severe, affecting more than 50 percent of watermelon acreage in southwest In...

The density of microcapsules was compared on 'Golden Delicious' mature and immature foliage, fruit, and 1-yr-old limbs after dip treatments with Phase III oriental fruit moth, Grapholita molesta (Busck), microencapsulated pheromone. Microcapsules were counted with a dissecting microscope at 50x magnification after apple tissues were treated with a two-step dye staining process to increase the v...

Purpose: One of the most important issues regarding radio frequency electromagnetic fields (RF‐EMF) is their effect on genetic material. Therefore, we investigated the cytogenotoxic effects of 900 MHz radio frequency electromagnetic fields (RF‐EMF) and the effect of a recovery period after exposure to RF‐EMF on bone marrow cells of immature and mature rats. Materials and methods: The immature a...

background: most studies on anabolic-androgenic steroids abuse have been done in adult rats, but few data are available to immature. objective: this study was conducted to assay the effect of nandrolone decanoate (nd) on the testis and testosterone concentration in male immature rats compare with mature ones in short and long time. materials and methods: 40 mature rats were divided into 4 group...

This study assessed the viability of using planted, mature rice fields in mitigating diazinon (an organophosphate insecticide) runoff toxicity using aqueous 48 h Hyalella azteca whole effluent toxicity bioassays. Rice fields decreased diazinon concentrations 80.1%-99.9% compared with 10.8% in the unvegetated field control. H. azteca survival responses coincided with observed diazinon concentrat...

Stand structure, species richness and population structures of tree species were characterized in 12 stands representing 50 y of succession following slash-and-burn agriculture in a tropical dry forest in lowland Bolivia. Estimates of tree species richness, canopy cover and basal area reached or surpassed 75% of mature forest levels in the 5-, 8-, and 23-y-old stands respectively. Total stem de...

About two-thirds of fields that exist in the world right now are classified as mature fields. Mature usually have a lot problems occurred during production. field is which has produced much fifty percent their established proved plus probable resources estimation or for more than twenty-five years. Empowerment well can be increasing efficiency productivity. Productivity decline caused by low ma...
