UltraPerformance LC (UPLC) in hydrophilic interaction chromatography (HILIC) separation mode is becoming a routine and widely recognized technique for rapid, efficient, sensitive, and reproducible analysis of 2-aminobenzamide (2-AB) labeled glycans. Even though 2-AB is now the most common glycan labeling reagent, its use is limited by low MS sensitivity. Recent reports on LC/FLR/MS of glycans t...

Background Sensitization to food allergens is supposed mostly to be caused by ingestion of the allergen. However, sensitization may also be initiated in the respiratory tract or through the skin. Little is known about sources and prevalence of food allergens in environmental samples. We aimed to describe the presence of food allergens in mattress dust from the homes of 13 year old Norwegian ado...

In this note based on paper [3] we deal with domains D (i.e. connected open subsets) of a Finsler manifold (M, F ). At first we carry out a comparison between different notions of convexity for their boundaries. Then a careful application of variational methods to the geodesic problem yields that the convexity of ∂D is equivalent to the existence of a minimal geodesic for each pair of points of...

This paper develops and analyzes a principal-agent model for product specification and production motivated by “core buying” decisions at Ford Motor Company. This model focuses on two important elements of the “core” buyer’s responsibility: (1) assessing the supplier’s capability and (2) allocating some or all of a fixed level of some buyer-internal resource to help the supplier. Under the cont...
