Objective: Diabetic patients are more likely to be infected and are at the higher risk of morbidity and mortality in COVID-19 pandemic. The aim of this study was to compare the preventive behaviours and perceived risk of COVID-19 in women with and without type 2 diabetes mellitus (T2DM). Materials and Methods: The analytical cross-sectional study was conducted from June to July 2020 on 151 par...

This paper presents the comprehensive analytical design and numerical performance evaluation of novel millimetre-wave (mm-wave) switched-beam networks, based on the Rotman lens (RL) array feeding concept. These passive array devices have been designed for operation in the 28GHz frequency band, covering the whole 18–38 GHz frequency range. The primary objective of the work is to conduct a thorou...

The swimming, air-gaping, and agonistic behaviours of Heterobranchus longifilis (318 ± 67 mm) were examined while fish were in a fasted state under 12L:12D and variable group size (2, 5, 10 and 15 fish) in a 1000L aquarium. Fish exhibited a predominantly nocturnal activity pattern independent of group size. A diurnal peak of activity occurred, however, at the usual feeding time. A reduction in ...

Avoiding biological contaminants is a well-known manifestation of the adaptive system of disgust. In theory, animals evolved with such a system to prevent pathogen and parasite infection. Bodily products are human-universal disgust elicitors, but whether they also elicit avoidance behaviour in non-human primates has yet to be tested. Here, we report experimental evidence that potential exposure...

Tooth morphology and development can provide valuable insights into the feeding behaviour and evolution of extinct organisms. The teeth of Theropoda, the only clade of predominantly predatory dinosaurs, are characterized by ziphodonty, the presence of serrations (denticles) on their cutting edges. Known today only in varanid lizards, ziphodonty is much more pervasive in the fossil record. Here ...

The behaviour of a male American black bear Ursus americanus was observed for over 2400 h across all seasons of the year. Stereotypic pacing was most frequent, oriented away from the exhibit, and performed mainly after feeding during the period May-July; from August-November pacing was oriented towards the exhibit and performed mainly around feeding time. Placing bear odors in the enclosure sli...

This study was conducted to evaluate the effects of a toy on behaviour and body weight weaned pigs after mixing. Two groups (192 in total, control: without toy; treatment: with placed floor) housed pens (1.8 m × 1.4 m, 4 pigs/pen) were observed aid video technology for nine consecutive hours early (days 1 2) late 38 39) period Bodyweight at end (Mann-Whitney U-test, Z = -2.46, P 0.01) average ...
