introduction renal transplant is the best treatment of choice for patients with end-stage renal disease (1). annually, about 17000 patients receive deceased or living donor transplants, which help them promote health and self-efficacy (1-2). however, despite advances in transplant technology, patients face a number of post-operative challenges, which might lead to stress in patients, including ...

utilization of photodisintegration reaction of deuterium, 2h(?,n)1h, is a precise technique for determining the percentage of 2h in tritiated and natural water. the 23na(n,?)24na reaction is a suitable ?-source for producing the 2h(?,n)1h reaction. tehran research reactor was used as a neutron source for producing 24na isotopes. the bf3 detectors were used to detect the neutron emission of h2 c...

Background: A new treatment approach for most patients who have undergone early stage non-small-cell lung carcinoma (NSCLC), is wedge resection plus permanent implant brachytherapy. However, the specification of dose to medium at low energies especially in heterogeneous lung is unclear yet.Objective: The present study aims to modify source strength for different configurations of 125I and 103...

Introduction:  90 Sr/ 90 Y source  has  been  used  for  the  intravascular  brachytherapy  to  prevent  coronary  restenosis in the patients who have undergone angioplasty. The aim of this research is to determine the  dose distribution of  90 Sr/ 90 Y source in a water phantom.  Materials  and  Methods:  In  the  present  work,  MCNP  code  has  been  applied  to  calculate  the  dose  distri...

measuring salinity of water at different depths along six transacts at the mouth of the wetland and along five tributaries connecting the wetland to the sea the extent of caspian sea penetration into anzali wetland was determined. the results demonstrated a depth-dependent salinity gradient extending up to 10 kilometres into the wetland. a pattern of saltwater and freshwater interface is presen...
