Small corrections to the uncertainty relations, with effects in the ultraviolet and/or infrared, have been discussed in the context of string theory and quantum gravity. Such corrections lead to small but finite minimal uncertainties in position and/or momentum measurements. It has been shown that these effects could indeed provide natural cutoffs in quantum field theory. The corresponding unde...

The Nanobiosciences Unit of the Joint Research Centre’s Institute for Health and Consumer Protection and Eurocolour, the association of European pigments, dyes and fillers industry, have carried out a program of work to evaluate a number of instrumental methods of measuring particle size distributions as required for assessing compliance versus the EU Recommendation for the definition on nanoma...

In the present study, we examined insecticidal effect of Carifend® (BASF AG, Ludwigshafen, Germany; 163.2 mg m−2), an alpha-cypermethrin-coated polyester net, as well Carifend-like nets containing different rates alpha-cypermethrin, specifically 10, 30, 80, and 325 m−2, against two major stored tobacco insect pests, i.e., Lasioderma serricorne (Fabricius) (Coleoptera: Anobiidae) Ephestia elutel...

OBJECTIVE The aim was to examine the long term morbidity experience of men exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). METHODS A retrospective cohort morbidity study of 158 men first exposed to TCDD between 17 November 1953 and 16 November 1954 subdivided by chloracne state and back calculated TCDD blood lipid concentration, and 161 referents. Cause specific illness absence and adm...

Soybean is a valuable protein and oilseed crop ranked among the most significant of major crops. Field experiments were carried out in 2016–2019 South-East Poland. The influence soybean cultivars (Aldana, Annushka), nitrogen fertilizer (0, 30, 60 kg?ha?1 N) inoculation with B. japonicum (control, HiStick® Soy, Nitragina) on content fatty acids (FA) seeds was investigated three-factorial experim...
