The gene encoding stilbene synthase is frequently used to modify plant secondary metabolism with the aim of producing the self-defence phytoalexin resveratrol. In this study, strawberry (Fragaria x ananassa) was transformed with the NS-Vitis3 gene encoding stilbene synthase from frost grape (Vitis riparia) under the control of the cauliflower mosaic virus 35S and the floral filament-specific fi...
BACKGROUND There are few longitudinal studies that have examined the association of lung function decline with indoor mould and dampness. Lung function decline in relation to dampness and mould in the home has studied in adults over a 9 year period. METHODS Spirometry was performed twice in participants in the European Respiratory Health Survey (ECRHS I and II) who were initially examined age...
Abridged version of the AWMF guideline for the medical clinical diagnostics of indoor mould exposure
This article is an abridged version of the AWMF mould guideline “Medical clinical diagnostics of indoor mould exposure” presented in April 2016 by the German Society of Hygiene, Environmental Medicine and Preventive Medicine (Gesellschaft für Hygiene, Umweltmedizin und Präventivmedizin, GHUP), in collaboration with the above-mentioned scientific medical societies, German and Austrian societies,...
This article is focused on the infrared heating of shell metal moulds and optimization of temperature field on the surface of the mould. The upper part of the mould is heated by infrared heaters, and after the required temperature is attained the inner part of the mould is sprinkled with special PVC powder. The moulds are made of aluminium or nickel alloys. The described mathematical model allo...
Two decades of operating experience have shown that reducing the corner radius from 12–16 mm to 3 or 4 mm A finite element thermal stress model to compute is beneficial in reducing longitudinal corner cracking.4 In the thermomechanical state of the solidifying shell addition to lessening crack frequency, decreasing the corner during continuous casting of steel in a square billet radius also ten...
In this study, an experimental research was conducted in developing and characterising sugarcane bagasse pineapple leaf particulate re?nforced polyester res?n compos?tes. Unsaturated resin (UPR) reinforced with particulates varied proportions (0 – 25 wt. %) by mould casting. Morphology mechanical properties of the composites were examined. There a good dispersion resin. The composite demonstrat...
The nucleotide sequence reported for the Dictyostelium discoideum ceramidase is available on the DNA Data Bank of Japan (DDBJ). Ceramidases (CDases) are currently classified into three categories (acid, neutral and alkaline) based on their optimal pHs and primary structures. Here, we report the first exception to this rule. We cloned the CDase cDNA, consisting of 2142 nucleotides encoding 714 a...
Acellular slime mould Physarum polycephalum is a popular now user-friendly living substrate for designing of future and emergent sensing and computing devices. P. polycephalum exhibits regular patterns of oscillations of its surface electrical potential. The oscillation patterns are changed when the slime mould is subjected to mechanical, chemical, electrical or optical stimuli. We evaluate fea...
BACKGROUND This study examines whether leaf spectra can be used to measure damage to cassava plants from whitefly (Bemisia tabaci), and the potential to translate measurements from leaf to landscape scale in eastern Africa. Symptoms of the cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) viruses, and sooty mould (SM) blackening of lower leaves from whiteflies feeding on the ...
Allelic variation at 46 simple sequence repeat (SSR) marker loci well distributed across the sorghum genome was used to assess genetic diversity among 92 sorghum lines, 74 resistant and 18 susceptible to grain mould. Of the 46 SSR markers, 44 were polymorphic, with the number of alleles ranging from 2 to 20 with an average of 7.55 alleles per locus. Genetic diversity among the sorghum lines was...
