Background: Tobacco smoking and alcohol consumption have been intensively studied in the general population to assess their effects on the risk of breast cancer, but very few studies have examined these effects in BRCA1 and BRCA2 mutation carriers. Given the high breast cancer risk for mutation carriers and the importance of BRCA1 and BRCA2 in DNA repair, better evidence on the associations of the

BACKGROUND: A large tumor volume negatively impacts the outcome of radiation therapy (RT). Altered fractionation (AF) can improve local control (LC) compared with conventional fractionation (CF). The aim of the present study was to investigate if response to AF differs with tumor volume in oropharyngeal cancer.METHODS: Three hundred and twenty four patients with oropharyngeal cancer treated in a r

We argue that the neoliberal tradition and new public management reforms of the public sector effectively erode the core (liberal) democratic values of the rule of law and transparency. The tension between public law and managerially-influenced governmental policy is in practice resolved by the emergence of what we call “shadow management” in public administration, whereby managerial decisions tha

The ice cover presence on the surface of a lake insulates the water body from the atmosphere. This prevents or reduces the influence of processes which depend on the exchange between the atmosphere and the water surface. This implies significant reduction or elimination of some processes taking place at the open water surface; for instance, a substantial reduction in solar energy penetrating to th

The polygenic background of selectively bred diabetes models mimics the etiology of type 2 diabetes. So far, three different rodent models (Goto-Kakizaki rats, Nagoya-Shibata-Yasuda mice, and Oikawa-Nagao mice) have been established in the diabetes research field by continuous selective breeding for glucose tolerance from outbred rodent stocks. The origin of hyperglycemia in these rodents is mainl

A process-oriented, performance-based cost-model for manufactured parts has been assessed in its ability to capture sustainability. Literature has been reviewed and found 108 sustainability indicators, which have been compared with the input parameters in the cost-model. Based on a gap analysis, a framework for sustainable production evaluation has been developed. The framework considers performan

Stable HCCI combustion requires a proper level of fuel reactivity. This study shows that adding ethanol as a renewable fraction to low octane gasoline decreases the reactivity of the gasoline, while adding 2-ethyl hexyl nitrate (2-EHN) can enhance the reactivity of the blend and counter the effect of ethanol.The experimental apparatus consisted of a modified CFR engine for HCCI combustion equipped

The aim of this study is to analyse how the study group method aids student entrepreneurs when developing entrepreneurial knowledge through the experiential learning process, and why it is important to stimulate peer learning in an experiential entrepreneurship education context. Due to a more experiential perspective on learning, the environment in which students learn, what students learn and whThe aim of this study is to analyse how the study group method aids student entrepreneurs when developing entrepreneurial knowledge through the experiential learning process, and why it is important to stimulate peer learning in an experiential entrepreneurship education context.

In 1977 several patients were seen with soft-tissue sarcomas and previous exposure to phenoxy acids. This clinical observation resulted in a case-referent (case-control) study being undertaken which showed that exposure to phenoxy acids or chlorophenols, which are chemically related, gave a roughly six-fold increase in the risk for this type of tumor. A further case-referent study of soft-tissue s

A number of men with malignant lymphoma of the histiocytic type and previous exposure to phenoxy acids or chlorophenols were observed and reported in 1979. A matched case-control study has therefore been performed with cases of malignant lymphoma (Hodgkin's disease and non-Hodgkin lymphoma). This study included 169 cases and 338 controls. The results indicate that exposure to phenoxy acids, chloro
