A brief study on the effects of storage conditions on sexual lubricant components in the presence of a biological fluid.

This study illustrated the effects of environmental conditions (i.e., temperature) on the components of a condom lubricant in the presence of vaginal secretion.

Utilization and recycling of wood ashes from industrial heat and power plants regarding fertilizer use.

To achieve a sustainable circular economy for wood ash, the reuse of wood ash in agriculture and forestry is important. To evaluate the usability of ash from the combustion of natural as well as waste wood for application as fertilizer, wood fuel and corresponding ash fraction samples (n = 86) of four industrial wood-fired heat and power plants (>20 MW) were investigated. In different ash fractions, the concentrations of heavy metals (As, Cd, Pb, Ni, Tl, Zn) and plant nutrients (N, P, K, Ca) were assessed with regard to relevant legislation from the European Union and from selected European countries (Germany, Austria and Finland).

A longevity study to determine appropriate storage conditions for sexual lubricants using spectroscopic and spectrometric techniques.

There has been an increase in the number of reported cases in which assailants have used a condom or sexual lubricant. Sexual predators understand that DNA from seminal fluid is one of the main forms of evidence used to connect a suspect to a victim or crime scene; therefore, the use of condoms in sexual assault cases has increased. This dilemma has led to research into other types of trace evidence (e.
