A growing body of evidence suggests that resources invested in reproduction often come at the expense of the ability to mount an immune response. During mating, female sagebrush crickets, Cyphoderris strepitans, consume the ends of the male's hind wings and ingest his haemolymph. Previous research has shown that this behaviour impairs the ability of males to secure additional matings. One hypot...

ninteen samples of dust from wool and carpet-weaving places around tabriz were collected. dust mites of wool and carpet-weaving places were separated and identified based on morphological characteristics. genus and species of mites per gram of dusts, were determined. the results showed that dominant population of mites were:dermatophagoides farinae (64%), dermatophagoides pteronyssinus (21.5%),...

The stimulation of the human sensory receptors by compounds present in virgin olive oils (VOOs) gives rise to the sensory attributes that describe its particular aroma. The sensor panel evaluation and the molecules responsible for sensory perceptions of virgin olive oil quality are elucidated. The methodology for the evaluation of the sensory characteristics of VOOs is reported, and typical fla...

Life history parameters and reproductive behaviors of the harlequin bug, Murgantia histrionicaHahn (Heteroptera: Pentatomidae), were determined. Total developmental time from egg to adultwas 48d.After a sexualmaturationperiodof 7d, both sexesmated repeatedly,with females layingmultiple eggmasses of 12 eggs at intervals of 3 d. Adult females lived an average of 41 d,whereas adult males lived an ...

The scope of this paper is the rationale and significance of the virgin birth, not the historical evidence for it. But in fact the rationale and significance are as important for the defence of the virgin birth as is the historical evidence. One of the main charges against it has been that it is theologically superfluous, dubious or even heretical. On the other hand, defenders of the virgin bir...

In Estonia, up to 90% of local wool is not adequately valued, while in Norway, due the well-functioning wool-buying and -sorting system, a large part used purposefully. However, both countries have room for improvement terms better usage wool. This article provides an overview Estonian-Norwegian research conducted from 2020 2023 its main results. During study, was collected three Estonian Norwe...

Natural dyes gained increasing attention due to environmental considerations. Many of the dye plants have also medicinal values. This study aimed to evaluate the effect of 25 plants as dyes and their dyed wool yarns against microorganisms. Prokaryotes were found to be more sensitive to dye extracts than eukaryotic microorganisms and dyestuff from Punica granatum, Berberis vulgaris, Agrimoni...
