This study determined whether marked hyperthermia alone or in combination with dehydration reduces the initial rate of rise in O(2) consumption (VO(2) on-kinetics) and the maximal rate of O(2) uptake (VO(2 max)) during intense cycling exercise. Six endurance-trained male cyclists completed four maximal cycle ergometer exercise tests (402 +/- 4 W) when euhydrated or dehydrated (4% body wt) with ...

Abstract Most tungsten (W) and tin (Sn) deposits are associated with highly evolved granites derived from the anatexis of metasedimentary rocks. They commonly separated in both space time, rare cases where W Sn mineralization part a single deposit, two metals temporally separate. The factors controlling this behavior, however, not well understood. Our compilation whole-rock geochemical data for...

PURPOSE Increased core temperature (T(c)), impaired cardiovascular function, and dehydration contribute to fatigue during prolonged exercise in the heat. Although many studies have examined mechanisms addressing these factors, few have investigated the effect of cold beverage temperature on thermoregulation and exercise performance in the heat. METHODS Citations from MEDLINE (Ovid), Sport Dis...

• Nb 2 O 5 · n H proved to be a stable and efficient catalyst for the dehydration of citric acid at mild reaction temperatures. Investigation interaction with surface by 13 C MAS NMR. Synthesis bifunctional Pd/Nb via low-temperature reduction method preserve properties support. Yields tricarballylic exceeding 90% over multiple runs. Recently, sequence was developed production acid, an interesti...

Amorphophallus paeoniifolius known as Elephant foot yam is a highly potential tropical tuber crop of Areace family. The tubers are rich in nutrients. It is a healthy low-fat food containing a good source of protein as well as starch. It is a natural product that is high in fiber, rich in potassium, calcium (50 mg g-1), phosphorus (34 mg g-1) vitamin A (260 IU g-1), vitamin B6, as well as with t...

The osmotic dehydration causes water removing from food and also a soluble solid uptake into thefoodstuffs. However, large penetration of solute into the food becomes a major problem in osmoticdehydration.Pre-coating the food to be dehydrated with an artificial, edible barrier was also explored as a wayto efficiently hinder solute penetration. In this study the effect of edible coating (CMC),co...

Liquid desiccants such as glycols are used in dehydration process, among which Triethylene Glycol (TEG) is considered as a common choice. The addition of nanoparticles to TEG as the base fluid is one of the prevalent method to improve thermal properties of TEG. In this study, an experimental investigation was performed on thermal conductivity of TEG-based nanofluids with 20 and 40 nm diameter c...

Isoenzyme profiles of peroxidase [EC 1.11.1.7], superoxide dismutase (SOD)[EC 1.15.1.1] and catalase [EC 1.11.1.6] in the endosperm and roots of wheat seedlings germinated under chronic stress conditions were investigated. Low and high temperature, 0.2 M NaCl and 0.5 M sucrose were applied as stress factors. Germination of seeds in the presence of ABA was used as a dehydration stress confirming...

A potential drawback with the use of mannitol as a bulking agent is its existence as mannitol hemihydrate (MHH; C₆H₁₄O₆·0.5H₂O) in the lyophile. Once formed during freeze-drying, MHH dehydration may require secondary drying under aggressive conditions which can be detrimental to the stability of thermolabile components. If MHH is retained in the lyophile, the water released by MHH dehydration d...
