Tungsten and Copper (II) Oxide Mixtures as Gasless Time Delay Compositions for Mining Detonators.

The widespread use of pyrotechnic compositions in time delay detonators is the reason for research aimed at expanding knowledge of the combustion properties of new pyrotechnic mixtures, whose components react with each other in the solid or liquid state. Such a method of combustion would make the rate of combustion independent of the pressure inside the detonator. This paper presents the effect of the parameters of W/CuO mixtures on their properties of combustion.

Public attitudes towards sexual behavior-Results of the German Health and Sexuality Survey (GeSiD).

Population-level data on predictors for attitudes towards sexual behavior are missing for Germany. The current study investigated sexual attitudes in the German population with regard to sociodemographic and sociocultural factors. Data originated from the German Health and Sexuality Survey (GeSiD; N = 4,955) carried out from October 2018 to September 2019.

Some Aspects of the Burning Process of Antimony and Potassium Manganate(VII) Compositions.

Antimony and potassium manganate(VII) compositions are widely used in time delay elements of detonators. Despite the existing literature on such systems, there is no complete information on the burning process of Sb/KMnO compositions in closed systems. There are also no data on the heat of their combustion in conditions of increased pressure without the access of oxygen from the air and on the composition of solid combustion products.

Improving hospital hygiene to reduce the impact of multidrug-resistant organisms in health care--a prospective controlled multicenter study.

Background: Nosocomial infections are the most common complication during inpatient hospital care. An increasing proportion of these infections are caused by multidrug-resistant organisms (MDROs). This report describes an intervention study which was designed to address the practical problems encountered in trying to avoid and treat infections caused by MDROs.
