groundwater resources are the main source of water supply in many arid countries such as iran. because of uncontrolled increasing of the population, limitation of surface water resources and excessive extraction from aquifers, sharp drop in groundwater level in many plains such as khezel plain located in hamedan province was occurred. khezel plain is important because of strategic crop farming ...

background and objectives: hospital is the largest and most costly operating unit of healthcare system. provision of optimal care requires that hospital administrators identify hospital performance based on relevant indicators. this study used the pabon lasso analysis to assess the performance of hospitals and identify strategies towards an improved hospital performance.   methods: this cross-s...

rade control structures are used to control bed erosion in steep small rivers mostly in the mountains. scour downstream of this structure can lead to failure. over the past years, the effect of different variables on this phenomena have been studied, however the effect of upward seepage which is common due to head difference of the banks water table or water surface level between the upstream a...

Muscle wilting meltdown, air gulping short of oxygen feeling, brain blood vessels flayed on a laundry line in the wind, metal rods in the back of head . . . someone crushing your ribcage, limbs giving out, mesh bag constricting head, 'pingers': those first small headaches that warn of bigger headaches, 'back of head clamp' . . . headache, increased gravity feeling, being pushed backward into be...

BACKGROUND Care of patients with enteral feeding tubes often is based on tradition and textbook guidance rather than best evidence. Care practices can vary widely both between and within institutions, and this was the case at a northeastern military medical center that served as the site for this evidence-based protocol development and implementation project. OBJECTIVES The purpose of this st...

OBJECTIVE The study aimed to evaluate the effects of putting a sandbag on femoral access site after cardiac invasive procedure and changing patients' position in bed on vascular complications rate and the severity of back pain related to the duration of bed rest after procedure. METHODS This randomized controlled study included 169 patients divided into five different groups assigned randomly...

BACKGROUND It has been suggested that placing critically ill ventilated patients in a semirecumbent position minimizes the likelihood of nosocomial pneumonia. AIM This pilot study explores whether the incidence of ventilator-acquired pneumonia (VAP) can be reduced by elevating the head of the bed to 45 degrees. METHODS The design is quantitative in nature, using a randomized controlled tria...

Palm kernel shell is an important bioenergy resource in Thailand. However, due to elevated alkali content in biomass ash, this oil palm residue shows high tendency to bed agglomeration in a fluidized-bed combustion system using conventional bed material (silica sand). In this study, palm kernel shell was burned in the conical fluidized-bed combustor (FBC) using alumina and dolomite as alternati...
