The aim of this paper to draw attention to several aspects of the algebraic dependence in algebras. The article starts with discussions of the algebraic dependence problem in commutative algebras. Then the Burchnall-Chaundy construction for proving algebraic dependence and obtaining the corresponding algebraic curves for commuting differential operators in the Heisenberg algebra is reviewed.

Advanced driving assistance systems that offer support by operating for example longitudinal control will have an effect on the transport system. Previous studies have also shown that drivers may be slower to respond in hazardous situations with systems like adaptive cruise control (ACC) engaged, if the system suddenly fails. Little understanding has, so far, emerged to explain why. In this thesis

A report from the conference Post-Colonialism and Global Migration and the exhibition Inclusion/Exclusion held in Graz, Austria, in 1997.

The release of two compositionally different solutes from a composite gel composed of two different populations of microgel particles embedded in a single bulk gel matrix is described, showing the potential of the "plum-pudding gel" as a multifunctional platform for controlled surface release. One hydrophobic solute (pyrene) and one hydrophobic and charged solute (rhodamine 123) were chosen as the

BACKGROUND: Hereditary non-polyposis colorectal cancer (HNPCC) (Lynch cancer family syndrome I (LCFS1) and II (LCFS2)) is one of the most common hereditary cancer disorders. HNPCC results from dominantly inherited germline mutations in mismatch repair (MMR) genes, leading to genomic instability and cancer. No predictive physical signs of HNPCC are available to date. AIMS: Increased complexity in t

Previous research has documented intergenerational transmission of human capital from children to parents. Less is known, however, about heterogeneity in this 'upward transmission' in low-resource settings. We examine whether co-resident adult children's education is associated with improved health among older parents in India, using nationally representative data from the 2014 Indian National Sam

The water exchange between the sea and a lagoon or bay through an inlet due to tides is a classical topic that has been investigated in a large number of studies (Keulegan, 1967; O’Brien and Dean, 1972; O’Brien and Clark, 1974; Escoffier, 1977). In this paper, a simple semi-analytic model of the flow induced by tides through an inlet connecting the sea to a lagoon or bay is developed. The model is

This dissertation investigates how different regions are financially integrated with the US capital markets and how the level of integration has changed over time. The research has been conducted by using an event study methodology to examine the impact on domestic stock prices following foreign cross-listings on US stock exchanges. A sample of 556 ADR programs initiated by companies from 38 count

Vårt syfte med denna uppsats är att klarlägga hur en offshoringprocess förändrar en organisation, samt ta reda på huruvida denna process påverkar kärnkompetensen. Denna studie bygger på en kvalitativ ansats i form av semistrukturerade intervjuer och dokumnetstudier. De teorier som använts har varit de fyra Idealteorierna av Van de Ven och Poole samt Prahalad och Hamels teori kring begreppet kärnko

Tortilla samples were elaborated by four small commercial factories in Mexico, employing masas prepared with the traditional nixtamalization process. Samples were stored at 4°C for up to 72 hours and their chemical composition and in vitro starch digestibility features were evaluated. Chemical composition did not change with the storage time, but soluble carbohydrates decreased slightly during sto

In a Storage-Ring Free-Electron Laser (SRFEL) giant pulses can be produced by the interaction between the light stored in the optical cavity and an electron beam with low energy-spread (cold beam). This interplay produces the heating of the beam. After the generation of a single giant pulse the overlap between electrons and radiation is periodically prevented for a time necessary to dump the energ

Debates on adaptation in rural Africa rarely consider how responses to climate variability vary by wealth group. This study examines differences across wealth groups based on principal component analysis and cluster analysis triangulated with participatory methods. Results indicate that perceptions of weather variability and extreme events are detected by most households regardless of wealth statu

Aim: Students with hearing loss (HL) often fall behind hearing peers in complex language tasks such as narrative writing. This study explored the effects of school grade, gender, cognitive and linguistic predisposition and audiological factors on narrative text quality in this target group.Method: Eleven students with HL in Grades 5–6 and 7–8 (age 12–15) who took part in a writing intervention wro
