an earthquake with magnitude ms = 6.5 on the richter scale occurred in december 26th, 2003 in bam region in southeastern part of iran. this study investigates the chemical variations of the groundwater resources in the effected region. for this purpose, 30 wells were selected and chemical compounds, in terms of cations (ca+2, mg+2, na+, k+); anions (hco3, so4, cl, no2), as well as ec, tds and p...
Background: The growth and evolution are among the basic sciences in pediatricsAll of the health staff should be familiar with infants care and the natural pattern of their growth. The present study aimed to help the health staff in urban society of Bam and Baravat, Iran to solve infants growth disorders. Methods: This cross-sectional study was done in 8 health centers of Bam and 2 health cente...
background: radon is one of the most important radioactive elements which is released by natural decay of available uranium and radium in the ground. the presence of radon gas is common, wherever those faults are located there. radon concentration of various drinking water resources of bam villages; located near bam fault; was measured. materials and methods: this cross-sectional study was cond...
Chemical quality change of the underground water resources of Bam andBaravat plain between 1997-2003
Introduction: Freshwater shortage and its sustainability and unsustainability are under consideration across the world. The fact that considerable parts of Iran are located in the arid and semiarid regions, is indicative of these geographical and climatic characteristics. This descriptive study is conducted to evaluate the chemical quality of water in Bam and Baravat plain and the variations ...

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
The transition from a Drosophila ovarian germline stem cell (GSC) to its differentiated daughter cell, the cystoblast, is controlled by both niche signals and intrinsic factors. piwi and pumilio (pum) are essential for GSC self-renewal, whereas bag-of-marbles (bam) is required for cystoblast differentiation. We demonstrate that Piwi and Bam proteins are expressed independently of each other in ...
The Drosophila germ-cell lineage has emerged as a remarkable system for identifying genes required for changes in cell fate from stem cells into more specialized cells. Previous work indicates that bam expression is necessary for cystoblast differentiation; bam mutant germ cells fail to differentiate, but instead proliferate like stem cells. This paper reports that ectopic expression of bam is ...
Bag of Marbles (Bam) is a stem cell differentiation factor in the Drosophila germ line. Here, we demonstrate that Bam has a crucial function in the lymph gland, the tissue that orchestrates the second phase of Drosophila hematopoiesis. In bam mutant larvae, depletion of hematopoietic progenitors is observed, coupled with prodigious production of differentiated hemocytes. Conversely, forced expr...
