Effects of chemically-passive fire suppressants on laminar premixed hydrogen flames were investigated by combined use of microgravity experiments and computations. The experiments used a short-drop freefall laboratory facility that provides at least 450 ms of 10 2 g. Near-limit laminar burning velocities were measured for outwardly propagating spherical stoichiometric hydrogen-air flames with v...

BACKGROUND When the etiology of a patient's chronic cough is established, specific antitussive therapy that is aimed at a particular cause of cough is highly effective. Nevertheless, in certain situations, therapy with cough suppressants, which previously were classified as nonspecific antitussive therapy, and which aim at suppressing the cough reflex regardless of the cause of cough, will be n...

Evidence-Based Answer Phentermine and diethylpropion are appetite suppressants approved for use in the United States as adjuncts in the treatment of obesity. These agents demonstrate a modest weight loss benefit when combined with dietary modifications and exercise. (Strength of Recommendation: B, based on a randomized trial and a meta-analysis.) No current evidence is available on the long-ter...

Polysaccharide biopolymers have been shown to be alternatives established dust suppressants. This study investigates the potential of 14 polysaccharides and proteins from diverse botanical (corn, pea, wheat, cellulose, potato, fava bean) animal (pig, chicken, cow) sources as suppressants on two mine soils (medium-grained sand fine-grained silica sand). Results laboratory tests demonstrate that ...

Inorganic fertilizers containing ammoniacal nitrogen or formulations releasing this form of N in the soil are most effective for suppressing nematode populations. Anhydrous ammonia has been shown to reduce soil populations of Tylenchorhynchus claytoni, Helicotylenchus dihystera, and Heterodera glycines. The rates required to obtain significant suppression of nematode populations are generally i...

The objective of this study was to evaluate the efficacy and safety associated with treatment available to prevent an acute attack of gout when initiating a urate-lowering therapy (ULT). We retrospectively reviewed patients who were diagnosed with gout and treated with ULT during the period from January 2000 to January 2014. They were divided into three groups, 75 patients without prophylaxis t...

The management and treatment of the tumors depends mainly upon the size of the tumor, its location and extent of metastasis. If symptoms begin to appear it means that most likely the tumor has spread to such an extent that treatment is going to be highly challenging. An open heart surgical excision of the tumor can be done if the tumor is localized. In cases where excision cannot be done due to...
