The fundamental problems related to uncertainty in quantitative risk analyses, used in decision making in safety-related issues (for instance, in land use planning and licensing procedures for hazardous establishments and activities) are presented and discussed, together with the different types of uncertainty that are introduced in the various stages of an analysis. A survey of methods for the...

Various normative decision theories are discussed in the context of fire risk management. A method suitable for practical decision making in respect to fire safety investments is presented and exemplified. The method involves the use of second-order probabilities to represent uncertainty regarding probability values. A discussion on the use of Bayes theorem in combination with decision analysis...

Introduction Uterine rupture is an obstetric emergency associated with maternal and neonatal morbidity. The main risk factor a prior cesarean section, occurring in subsequent labor. aim of this study was to assess the uterine by labor duration management. Material methods This Swedish register-based cohort women who underwent 2013–2018 after primary section (n = 20 046). Duration exposure, calc...

The preventive effect of the serine protease inhibitor FUT-175 (nafamostat mesilate), a potent inhibitor of the complement system, against vasospasm was evaluated in 34 high risk patients with thick and diffuse subarachnoid hemorrhage (SAH) demonstrated by computed tomography corresponding to Fisher group 3. All patients underwent surgery within 96 hours following SAH and received the thromboxa...

We previously reported on a 3-hydroxy fatty acid that is secreted via cryptococcal capsular protuberances - possibly to promote pathogenesis and survival. Thus, we investigated the role of this molecule in mediating the fate of Cryptococcus (C.) neoformans and the related species C. gattii when predated upon by amoebae. We show that this molecule protects cells against the phagocytic effects of...

The low-flow regime of a river may be described in terms of various characteristics (indices). These characteristics may have multiple use in different areas of water-related research and practice and uncertainty often exists as to which low-flow characteristic is the most suitable for a specific purpose. The paper illustrates that many low-flow characteristics exhibit a strong intercorrelation...
