Johan Jakob Borelius var professor i teoretisk filosofi vid Lunds universitet från 1866-1898. Boken belyser den syn på filosofin som Borelius gav uttryck för när han tillträdde sin professur. Vidare ges en inblick i hans trettioåriga verksamhet som professor. Särskilt utrymme ägnas åt Borelius syn på motsägelsesatsens innebörd och giltighet, liksom det stora verket "Metafysik" som han arbetade på

Biografisk artikel om Elsa Collin (1887-1941), kvinnlig studentpionjär, skådespelerska, poet, teaterkritiker etc.

Popular Abstract in Swedish Gastroesofageal refluxsjukdom är ett tillstånd som kännetecknas av att magsyra åker upp i matstrupen (reflux). Reflux är ett normalt fenomen som förekommer hos alla individer utan att orsaka symtom eller vävnadsskador. Hur detta normaltillstånd utvecklas till ett sjukdomstillstånd är ej helt klarlagt. Reflux förhindras normalt av en barriär vid övergången mellan matstruThere is a persisting controversy concerning the definition, etiology and pathogenesis of Barrett's esophagus. The dramatic and parallel increase in the incidence of esophageal and junctional adenocarcinoma over the past decades justifies an evaluation of the pathophysiology of premalignant metaplastic changes of the esophagus and the gastroesophageal junction. Patients were evaluated with upper G

The chapter defines mimetic schemas as dynamic, concrete and preverbal representations, involving the body image, which are accessible to consciousness, and pre-reflectively shared in a community. Mimetic schemas derive from a uniquely human capacity for bodily mimesis (Donald 1991; Zlatev, Persson and Gardenfors 2005) and are argued to play a key role in language acquisition, language evolution a

Popular Abstract in Swedish Inom medicin, och inom många andra tillämpningar, är uppgiften ofta att utifrån en serie observationer ge ett jakande eller nekande svar på en viss fråga. Exempelvis måste en läkare avgöra om en patient med bröstsmärtor lider av akut hjärtinfarkt eller inte. Artificiella neurala nätverk är en sorts datorprogram som själv förmår "lära" sig att svara på sådana frågor. NäArtificial neural network (ANN) and combinatorial optimization algorithms are developed, and applied to the medical domain. A novel method for training an ensemble of ANN is presented, based on random weight updates alternated with replication of networks with low error. The evolution of the ensemble is explored, with particular emphasis on its diversity and internal correlation. The performance

The aim of this chapter is to move the issue a bit beyond the polarized views of profound critical reflection versus excessive trust in the checking procedures behind standards. We claim that the polarized views are largely due to an over-simplistic understanding of transparency. By comparing practical policy processes surrounding various standards, we aim to provide nuance to the issue of transpa

We consider the problem of nding a long, simple path in anundirected graph.W e present a polynomial-time algorithm that ndsa path of length (log L/ log log L)2, where L denotes the length ofthe longest simple path in the graph.This establishes the performanceratio O|V |(log log |V |/ log |V |)2 for the Longest Path problem, whereV denotes the graphs vertices.

As current silicon-based microelectronic devices and circuits are approaching their fundamental limits, the research field of nanoelectronics is emerging worldwide. With this background, the present thesis focuses on semiconductor nanoelectronic devices based on ballistic and quantum effects. The main material studied was a modulation doped In0.75Ga0.25As/InP semiconductor two-dimensional electr
