Due to the massive loss of leaves in parks and green spaces and big cities such as Isfahan and the lack of domestic production of leaf vacuum shredder machine for use in large green spaces of parks, the design and construction of the collecting and recycling by the system is need so the design of the vaccum section which is one of the main parts and includes entrance, channels and ducts and exh...

CONTEXT Urine specific gravity (USG) has been used to estimate hydration status in athletes on the field, with increasing levels of hypohydration indicated by higher USG measurements (eg, greater than 1.020). Whether initial hydration status based on a urine measure is related to subsequent drinking response during exercise or athletic competition is unclear. OBJECTIVE To determine the relati...

Fluid imbalance, caused by fluid loss and changes in capillary permeability, occurs during the acute phase of burns and scalds, and the extent of the loss has been shown to depend on the body weight and surface area damaged. The blister fluid may contain protein in a concentration up to 6 g./100 ml. and sodium up to 160 mEq/l., resembling lymph and interstitial fluid in the burned patient (Cope...

CONTEXT Considerable controversy regarding fluid replacement during exercise currently exists. OBJECTIVE To compare fluid turnover between National Football League (NFL) players who have constant fluid access and collegiate football players who replace fluids during water breaks in practices. DESIGN Observational study. SETTING Respective preseason training camps of 1 National Collegiate ...

Introduction: Congenital anomalies of the cochlea and labyrinth can be associated with meningitis and varying degrees of hearing loss or deafness. Despite antibiotics, meningitis remains a life threatening complication.   Case Report: We report a case of recurrent meningitis following episodes of otitis media in a cochlear implantee child with bilateral vestibulocochlear malformation, due to f...

Radial inflow turbines are the preferred architecture for energy extraction from the organic Rankine cycle and the supercritical CO2 Brayton cycle at smaller scales. For such turbines it is possible for fluid to be delivered to the first stage by either a volute or plenum delivery system. For high pressure supercritical CO2 turbines, there are no fully documented fluid delivery systems in liter...

The purpose of this research was to investigate rates of residual-limb fluid volume change within one day for people with transtibial limb loss. Rates of fluid volume change during 30 min test sessions of sitting, standing, and walking activities were measured twice a day, once in the morning and once in the afternoon, on 12 regular prosthesis users with the use of bioimpedance analysis. Betwee...

For people who wear a prosthetic limb, residual-limb fluid volume loss during the day may be problematic and detrimentally affect socket fit. The purpose of this research was to test the capability of a novel liner with adjustable bladders positioned within its wall to mitigate volume loss and facilitate limb fluid volume recovery and retention. Bioimpedance analysis was used to monitor fluid v...

Venous blood leaving a solid tumor showed higher erythrocyte concentration than did aortic blood. Net fluid loss of efferent blood as calculated from hematocrit differences was 2.7 to 6.7% of flow volume, 4.5 to 10.2% of perfusing plasma volume, or 0.14 to 0.22 ml fluid per hr per g in 2 to 5 g transplanted MTW9 and Walker 256 mammary carcinomas, and primary N-nitrosomethylurea- and 7,12-dimeth...
