Oranic acid anhydrides (OAAs) are important reactive, low-molecular-weight industrial chemicals which induce allergic rhinitis and asthma in exposed subjects. Specific IgE has been demonstrated in a large proportion of OAA-exposed workers. The characteristics of the OAAs make them excellent model compounds for studies of quantitative structure-activity relationships (QSAR) of allergenicity. In the

Polyphosphoinositides, the different phosphorylated variants of the phospholipid phosphatidylinositol (PtdIns), are used in a wide array of intracellular mechanisms in eukaryotic cells. The phosphorylation of PtdIns at carbon D4, catalyzed by phosphatidylinositol 4-kinase, is an important step in the synthesis of several of these molecules. The presence of different isoenzymes of PtdIns 4-kinase i

We discuss the IAU resolutions B1.3, B1.4, B1.5, and B1.9 that wereadopted during the 24th General Assembly in Manchester, 2000, andprovides details on and explanations for these resolutions. It isexplained why they present significant progress over the correspondingIAU 1991 resolutions and why they are necessary in the light of presentaccuracies in astrometry, celestial mechanics, and metrology.

This paper examines references of visual product identity in product design. The perception of identity is the result of a composite experience of the presentational and representational dimensions of the product. As consumers to a large degree create their value perceptions of products and brands based on the design of the product, it is important for companies to understand how perceptions of id

Projects often suffer from lack of logistics considerations in the early phases. Since logistics is not the main focus of the people involved in the project, logistics solutions become reactive rather than proactive. With the increasing global competition, forcing companies to shorten time-to-market for their projects and becoming more cost effective, it becomes increasingly important to manage pr

Colonialism’ and ‘decolonization’ have been dealt with by postcolonial studies and, more recently, by scholars identified with the ‘de-colonial turn’. At the same time, in the ethnopolitically charged context of contemporary Bolivian society, colonialism and decolonization have become issues of political, existential and even cosmological import. This thesis identifies a need to root the ‘de-colon

The partitioning of 10% (w/w) lactic acid in ethylene oxide propylene oxide (EOPO) random copolymers and dextran T500 aqueous two-phase systems was studied. An analysis of variance design was applied to investigate the effect of pH, polymer concentration, and addition of polyethyleneimine to the aqueous two-phase systems. The lowest lactate partition coefficient of 0.09 was obtained at pH 6 in the

Purpose: Individuals with tetraplegia depend on alternative interfaces in order to control computers and other electronic equipment. Current interfaces are often limited in the number of available control commands, and may compromise the social identity of an individual due to their undesirable appearance. The purpose of this study was to implement an alternative computer interface, which was full

The rapidly growing interest in photocatalytic systems for direct solar fuel production such as hydrogen generation from water splitting is grounded in the unique opportunity to achieve charge separation in molecular systems provided by electron transfer processes. In general, both photoinduced and catalytic processes involve complicated dynamics that depend on both structural and electronic effec

This article identifies factors which contribute to households’ willingness to pay for improving and protecting a multiple-use water scheme in Ethiopia. It does so through descriptive statistics, a probit model and contingent valuation methods complemented with qualitative data. Estimates suggest farmers’ willingness to pay is based on gender, the prevalence of waterborne disease, the time to coll

This paper presents a novel approach for the elaboration of an integration strategy for controls and computing systems at large particle accelerator based research facilities. The approach is applied in a specific case study conducted at the world-leading neutron science facility European Spallation Source (ESS). First, an introduction to the term 'integration' in the Systems Engineering literatur

OBJECTIVE: Sleep disturbances and alterations of diurnal endocrine rhythms are associated with increased risk of type 2 diabetes (T2D). We previously showed that young men born small for gestational age (SGA) and with increased risk of T2D have elevated fat and decreased glucose oxidation rates during nighttime. In this study, we investigated whether SGA men have an altered diurnal profile of horm
