In his famous 1959 review, Walter Kauzmann clarified important features of the thermodynamic stabilities of proteins. The hydrophobic effect is recognised as an important contributor to the stability of proteins and an important determinant of their structural patterns. As generally understood, it depends on the unusual properties of cold water and its interactions with nonpolar solutes. Here w...

Energy consumption for hot water production is a major draw in high efficiency buildings. Optimizing this has typically been approached from a thermodynamics perspective, decoupled from occupant influence. Furthermore, optimization usually presupposes existence of a detailed dynamics model for the hot water system. These assumptions lead to suboptimal energy efficiency in the real world. In thi...

HISTORICAL DEVELOPMENT: The use of hyperthermia (heat) in the treatment of malignant tumors is as old as medicine itself. For example, the 5000-year old Edwin Smith Surgical Papyrus mentions heat as potential treatment for breast cancer [1]. Hippocrates, the father of medicine, proposed that surface tumors should be cauterized by application of hot iron. In modern times, more advanced methods (...

henbane hyoscyamus reticulatus l. is a plant species in solanaceae family that seeds hardly germinate because of seed dormancy. in order to determine the best methods for seed dormancy breaking in henbane, a experiment was conducted as a completely randomized design with three replications. the treatments included moist pre-chilling (at 4 °c) for 7, 14, 21 and 28 days, combined treatment of gib...

Hot-water dips with and without the additives abamectin and sodium hypochlorite were evaluated for control of Ditylenchus dipsaci infection of garlic seed cloves. All treatments were compared to hot water-formalin clove dip disinfection and to nontreated infected controls for garlic emergence, midseason infection, bulb damage, and yield at harvest in field plots in 12 experiments. Hot-water tre...

Allergic rhinitis is a common nasal disorder with a high impact on quality of life, high social costs in therapies, and a natural development towards asthma. Pharmacological therapy is based on several genres of medications, of which intranasal corticosteroids are currently the most widespread. Thermal water treatment has traditionally been used as adjunctive treatment for chronic rhinitis and ...

Numerous advanced surface modification techniques exist to improve bone integration and antibacterial properties of titanium based implants and prostheses. A simple and straightforward method of obtaining uniform and controlled TiO(2) coatings of devices with complex shapes is H(2)O(2)-oxidation and hot water aging. Based on the photoactivated bactericidal properties of TiO(2), this study was a...

Pressurized hot water extraction (PHWE) has become a popular green extraction method for different classes of compounds present in numerous kinds of matrices such as environmental, food and botanical samples. PHWE is also used in sample preparation to extract organic contaminants from foodstuff for food safety analysis and soils/sediments for environmental monitoring purposes. The main paramete...

Introduction: Radon-222 gas is a radioactive, colorless and odorless element that can cause lung cancer and stomach in humans with alpha-ray emissions. An important source of Radon-222 is the output water in springs, especially hot springs to emit ionision radiation. In this study, Rn-222 activity concentration and gamma dose rate levels in water sample of some selected hot spr...

Prestorage heat treatment appears to be a promising method of postharvest control of decay. Heat treatments against pathogens may be applied to fresh harvested commodities by hot water dips, by vapour heat, by hot dry air or by a very short hot water rinse and brushing. Heat treatments have a direct effect slowing germ tube elongation or of inactivating or outright killing germinating spores, t...
