(PhD Thesis;2021:89, Doctoral thesis, 2021)Childhood obesity is one of the most serious public health challenges of the twenty-first century (WHO, 2018). In this context, finding ways to make the healthier food choices the preferred ones, can be a valuable contribution ... -
Non-target and suspect characterisation of organic chemicals of emerging concern in air and biota
(PhD Thesis;2020:42, Doctoral thesis, 2020)Persistent organic pollutants (POPs) and other regulated organic chemicals are being monitored in the environment to evaluate the effectiveness of regulations and conventions, spatial and temporal trends as well as a ... -
Novel aspects of the ecophysiology of denitrifying bacteria and their roles in N2O emissions
(PhD Thesis;2017:91, Doctoral thesis, 2017)Environmental bacteria are in general limited by nutrient availability, and as the conditions fluctuate rapidly and unpredictably they must adapt or they will not thrive. This requires fast and adequate sensing and ... -
Objective methods of classification for beef- and pork carcases as a basis for evaluation of carcase yield
(PhD Thesis;2024:13, Doctoral thesis, 2024)Yield within the meat industry refers to the ratio and weight of tissues from the carcase. Carcase classification gives each carcase grades that determine the price paid for the carcase. Two aspects are especially important ... -
Parameters and pedigrees in forensic genetics and statistics
(PhD Thesis;2017:46, Doctoral thesis, 2017)With the rapidly evolving DNA technology today, there is a constant need of more robust statistical methods for analyzing the data. The sequencing techniques are improving, making more genetic markers available, and we are ... -
Physiological features of aging in honey bees (Apis mellifera)
(PhD Thesis;2019:52, Doctoral thesis, 2019)Aging and a decline in physiological resilience occur in most living organisms, including honey bee workers. Aging research in different organisms—from yeast, worms, insects, and mice to humans—has investigated several ... -
Polycyclic aromatic compounds (PACs) in ambient air of Svalbard : concentrations, seasonal trends, sources, and transformation processes
(PhD Thesis;2021:80, Doctoral thesis, 2021)Polycyclic aromatic compounds (PACs) are ubiquitous organic, gaseous, and particulate chemicals primarily emitted from incomplete combustion of fossil fuels, waste, and open biomass burning, including wildfires. Several ... -
Present health challenges in fresh and processed meat
(PhD Thesis;2016:28, Doctoral thesis, 2020-11-13)Processed meat intake is claimed to involve a higher risk of colon cancer. In particular, sausage intake is high and therefore has a potential for influencing consumers’ health. In Norway, sausage consumption has been ... -
Principal components of buffalo and cow milk from Bangladesh : proteolysis and lipolysis of buffalo, cow and omega-3 enriched milk by ex vivo digestion
(PhD Thesis;2014:52, Doctoral thesis, 2014)The aim of the study was to characterize and compare the Bangladeshi buffalo, Holstein cross, Indigenous cattle and Red Chittagong Cattle milk based on milk’s principal components, and further to investigate the proteolysis ... -
Production and characterisation of native whey and native whey products
(PhD Thesis;2016:15, Doctoral thesis, 2020-10-27)When microfiltration is applied in order to casein-standardise cheese milk, native whey (skimmed milk microfiltration permeate) is generated. Native whey consists of minor serum components that are allowed to be transmitted ... -
Production of microbial protein from brown seaweed and spruce wood and its use as a novel feed ingredient in aquaculture
(PhD Thesis;2018:46;, Doctoral thesis, 2018)With the world’s rapidly expanding population, it is necessary to provide sustainable and nutritious food. Aquaculture is the world’s fastest growing food production sector and carries with it some major tradeoffs and ... -
