Measurements of reflectance quantities collected in natural radiation conditions underpin quantitative Earth observation (EO) science through calibration, validation and atmospheric correction techniques. Despite their importance to the longevity of EO data, only a few studies have commented on the reliability of such measurements. This paper will report on results from three experiments. Each ...

Mate choice is based on the comparison of the sensory quality of potential mating partners, and sex pheromones play an important role in this process. In Drosophila melanogaster, contact pheromones differ between male and female in their content and in their effects on male courtship, both inhibitory and stimulatory. To investigate the genetic basis of sex pheromone discrimination, we experimen...

Why don’t workers follow Hazard Analysis Critical Control Point (HACCP) guidelines? Socio-psychological models have been used to describe factors that influence the implementation of food safety management systems (FSMSs) in food processing facilities. The theory of planned behavior posits that perceived control over one’s own behavior, one’s attitude and the influence of others are antecedents...

Congenital heart disease (CHD) is one of the most common congenital anomalies with an incidence of approximately 8–10 cases per 1000 live births. Technical development and continuing improvement in surgical methods have led to early interventions and an increased survival and consequently also a new group of patients in dentistry. The general aim of this thesis was to study the caries prevalenc...

abstract background and aims: probable risk factors of clinical anastomotic leakage and the role of defunctioning stoma in patients undergoing low anterior resection (lar) for rectal cancer, is still controversial. the goal of our study was to find out possible risk factors of anastomotic leakage and to locate the influence of protective stoma in the rate of anastomotic leakage. materials and m...

Several natural populations of D. melanogaster were investigated for the presence (or absence) of the Segregation Distorter ( SD) chromosomes and their suppressor systems. The SD chromosomes were found, at frequencies of a few percent, in two independent samples taken in different years from a Raleigh, North Carolina, population, whereas no SD chromosomes were found in samples collected from se...
