BACKGROUND This study evaluated adding reflective thermal inserts (RTI) to reduce the physiological strain during exercise-heat stress with a radiant load. RTI were used with a U.S. Army desert battle dress uniform, body armor, and helmet. METHODS Four male volunteers attempted four trials (10 min rest followed by 100 min walking at 1.56 m x s(-1)). All trials were at 40.0 degrees C dry bulb ...

To predict the polymer properties produced by free-radical polymerization of N-vinylpyrrolidone (NVP) in aqueous solution a detailed kinetic model has been developed. The allows to calculate chain length distribution, number branching points, and terminal double bonds (TDB). latter is accounted for since TDBs are precondition branching. While monomer conversion can be predicted sufficiently usi...

The purpose of this study was to examine the changes in technical and physical performance between the first and second half during official matches of Italian Serie A league. Further aim was to compare the technical and physical performance of the players of the more successful teams (ranked in the first 5 positions) with the players of the less successful teams (ranked in the last 5 positions...

The application of active magnetic bearings (AMBs) enables turbomachinery to increase power density, controllability and resilience external disturbances. However, due the limited load capacity AMBs, base shock excitations may result in contact between rotor touchdown (TDBs), which can seriously damage machine. This paper presents a dynamic analysis rotor-AMB-TDB system experiencing strong shoc...

The aim of the experiment was to evaluate effects of zinc gluconate (ZnGlu) and probiotic administration on the daily rhythm of cloacal temperature (tcloacal) in broiler chickens of different age groups during the hot-dry season. One-day-old broiler chicks (n = 60) were divided into groups I-IV of 15 chicks per group, and treated for 35 days: Group I (control) was given deionized water; Group I...

Language development in early childhood is a foundations both mastering academic skills and social skills. Delays intervention will increase the risk of children experiencing problems as adults. TDB kindergarten student with age 5 years 9 months who was identified expressive language developmental delay. The results assessment showed that not accordance its chronological age. Intelligence test ...
