Helicobacter pylori may cause gastritis, gastric/duodenal ulcer and gastric cancer. During infection, most H. pylori are found in the gastric mucus layer, but some are attached to, or have penetrated, epithelial cells. The aim of this study is to characterize the binding of H. pylori to gastric mucins and to investigate host changes that occur after inoculation. Results: H. pylori binds to mucins

In order to tap the energy saving and climate mitigation potential of the building sector, transaction costs of implementing energy efficient technologies need to be better understood and ultimately reduced. The objective of this paper is to identify and analyze the nature and scale of transaction costs resulting from the application of the passive house concept in energy efficient renovations. Re

Hormone-sensitive lipase (HSL) and protein kinase B (PKB) are enzymes that in different ways are associated with lipid metabolism. While HSL is the well-known lipolytic enzyme responsible for hydrolysis of stored triacylglycerols in adipose tissue, PKB is a recently identified serine/threonine protein kinase, ubiquitously expressed and involved in signal transduction pathways induced by insulin an

In response to stakeholder expectations from corporate social responsiblity (CSR), many firms create written policies about principles of social responsibility to be applied in their corporate activities. In this book, it is suggested that CSR could be integrated as part of the firm's marketing strategies. The perspective is that of a retail organisation. The retailer not only has immediate contac

Bone and soft tissue tumors (BSTT) constitute a heterogeneous group of neoplasms of mesenchymal and neuroectodermal origin. Although many BSTT are rare, it has become clear that BSTT are characterized by recurrent acquired chromosomal aberrations, and the general aim of this thesis have been to apply molecular genetic and molecular cytogenetic techniques to further characterize recurrent breakpoin

The thesis provides a discussion of the ecclesiology of the French Roman-Catholic theologian Henri de Lubac SJ (1896-1991) by showing how this is determined by his method of fundamental theology. I establish the term ?fundamental ecclesiology? for this inter-dependance of form and content, subject and object in theology; this is why his ecclesiology is sacramental in structure. I primarily use tex

Flexibility as well as constraints to the evolution of migration routes has the possibility of affecting large-scale patterns of geographical ranges of animals both by facilitating, but sometimes restricting, accessibility to and colonization of new regions. This dissertation concerns the broad-scale effects migration has on the distributional patterns of birds in the Arctic. I studied the circum

Malignant glioma is, with rare exceptions in younger adults, an uncurable brain tumor, as very few survive more than 1-2 years after diagnosis. Despite advances in recent years, current treatments such as surgery, radiotherapy and chemotherapy only prolongs the life of the patients. Because of the poor prognosis, several additional therapies have been investigated and are under development, such a

Why do some corporations become positioned as socially responsible and others as socially irresponsible? Here, an attempt is made to explore this issue. Within the established management literature it is held that managers do not understand corporate social responsibility (CSR), wherein the focus has been turned towards how corporations can work with CSR inside their organisation as a response to

I share my fascination of bird flight with many others, and here I summarise my thesis on the subject. This thesis emphasises the mechanics of bird flight by focusing on flight mechanics, wake dynamics and flight performance. Gliding flight performance of a jackdaw was measured in a wind tunnel and I conclude that the current model for predicting optimum wingspan as a function of forward gliding

Poor public perception can obstruct a construction project in a damaging way. Knowledge about public opinion should be considered as a relevant area of expertise for project managers and as an essential cost element in the planning and completion of construction projects. A consensual approach to a siting controversy requires informal face-to-face interaction among chosen representatives from all

The paper deals with durability of Self-Compacting Concrete with limestone filler during Thaumasite Sulphate Attack. For this purpose six concrete with varying amounts of limestone filler, particle size of limestone filler, pressure height during casting and mixing order were studied. One normal concrete (without limestone filler) with vibrator compaction was studied in parallel. In the ongoing ex

Based on Brandtler (2012), this paper argues that polarity items are sensitive to evaluability, a concept that refers to the possibility of accepting or rejecting an utterance as true in a communicative exchange. The main distinction is made between evaluable and non-evaluable utterances. The evaluable category comprises any clause that asserts, presupposes or entails the truth of an affirmative o

En solfångarhybrid har utvecklats och utvärderats på avdelningen för Energi och ByggnadsDesign på Lunds Tekniska Högskola, LTH. Solfångarhybriden, ”Solfönstret”, består av solcellslaminerade absorbatorer placerade i ett fönster bakom glasrutorna. Solfönstret finns byggt i ett enfamiljshus, Solgården, i Älvkarleö utanför Gävle. För att minska investeringskostnaderna för solel har reflektorer placer
