Combustion of ammonia (NH3) as a carbon-free alternative fuel has been recently widely studied, with vast majority of the burning velocity data obtained at room temperature. In the present study, the laminar burning velocity SL of NH3/air mixtures has been measured at unburnt gas temperature Tu from 298 K to 448 K, covering equivalence ratios from 0.85 to 1.25 and at 1 atm using the heat flux meth

The overall aim of this chapter is to present a guide in how to efficiently measure and statistically analyze text and numerical data using the online software SemanticExcel.com; we will focus on the following main functions: 1. Computing semantic similarity scores between the semantic representations of two sets of texts. 2. Testing whether the semantic representations of two sets of texts statis

Background: Intensive care unit (ICU)-acquired delirium is frequent and associated with poor short- and long-term outcomes for patients in ICUs. It therefore constitutes a major healthcare problem. Despite limited evidence, haloperidol is the most frequently used pharmacological intervention against ICU-acquired delirium. Agents intervening against Delirium in the ICU (AID-ICU) is an international

Aim: To describe the experiences of peer learning in psychiatric inpatient settings during clinical placement of undergraduate nursing students and to highlight the possibility for peer learning in psychiatric outpatient settings. Design: A qualitative inductive design. Method: Questionnaires with 14 students and 12 preceptors in inpatient and outpatient care and interviews with one student and on

Objective: To compare mode of birth in Robson group 1 according to administration of oxytocin for labour augmentation. Design and participants: A retrospective review of 724 medical records from women in Robson group 1 was performed. The outcome measurements were: mode of birth in relation to presence of labour dystocia when initiating augmentation with oxytocin, duration of augmentation with oxyt

The paper presents research results from the Marie Skłodowska-Curie Innovative Training Network INFRASTAR in the field of reliability approaches for decision-making for wind turbines and bridges. This paper addresses the application of Bayesian decision analysis for installation of heating systems in wind turbine blades in cases where an ice detection system is already installed in order to allow

Decision analysis is often used to help decision makers choose among alternatives, based on the expected utility associated to each alternative as function of its consequences and potential impacts. Environmental impacts are not always among the prioritized concerns of traditional decision making. This has fostered the development of several environmental problems and is nowadays a reason of conce

This study aims to reveal the obstacles to achieving quality in distance learning during the Coronavirus (COVID-19) pandemic and was based on a large sample of professors and students of universities in the Arab world (Algerian, Egyptian, Palestinian, and Iraqi). The primary aim of this research was to investigate the various ways in which students pursued their studies at home during the universi

Även om man redan under 1930- och 40 talen förstod att små vattendroppar under vissa förutsättningar kan förbättra släckeffektiviteten för vatten jämfört med större vattendroppar och slutna vattenstrålar, så var det inte förrän på 1990 talet som tekniken med fasta system med ”vattendimma” kommersialiserades. Incitamentet var i första hand det så kallade Montrealprotokollet och branden ombord på pModern, commercial water mist fire protection system technology evolved at the beginning of the 1990s due a need to replace halon fire-extinguishing systems and improve fire safety on passenger ships. This thesis documents the unknown water mist system development work by two Swedish companies during the 1970s and 1980s. It also documents the development of the first international installation rec

This report presents an integrated simulation-based approach to study the on-site production of concrete frameworks by considering the multiple effects of weather on work task productivity and concrete curing process. The suggested approach enable to systematically study how different weather conditions and the use of climate-improved concrete in combination with different methods to shield concre

The Hyogo and Sendai frameworks stress that risk assessments should inform plans. However, it is unclear how, in theory, risk assessments and plans are conceptually related and how, in practice, they inform each other. This study aims to fill this knowledge gap. Conceptually, it proposes an explicit link between risk assessments and plans via the capability of the responding organisation and its e

Different scientific communities produce different kinds of datasets that rely on different data descriptions, approaches, and logical organisations. In such an environment, it is essential to establish a knowledge communication framework that can guarantee some fundamentals, such as an inclusive description and documentation of the interdisciplinary digital resources, their long-term preservation

Deoxyribonucleoside triphosphates (dNTPs) are vital for the biosynthesis and repair of DNA. Their cellular concentration peaks during the S phase of the cell cycle. In non-proliferating cells, dNTP concentrations are low, making their reliable quantification from tissue samples of heterogeneous cellular composition challenging. Partly because of this, the current knowledge related to the regulatio

This paper summarizes the experimental and numerical investigations on an innovative hybrid joint for timber structures. A total of 12 hybrid dowel and bonding steel plate joints divided in four subgroups were investigated. Different parameters such as the presence of self-tapping screws and the surface treatment of the bonding steel plate, were studied. For two subgroups, a vulcanized rubber laye

Aim A key component of library management is meeting the needs of our users. This requires continuous analysis of user experience followed by library development. The aim of this study was to better understand the use and effect of general user surveys (GUS) and other methods of gathering user input for quality assessment and improvement of library activities. Methods Data collection was done via

The transitions to a low carbon and sustainable society are urgent, but at the current level and pace of action there is a significant risk we will escalate and exceed the goals of the Paris Climate Agreement and fail to achieve the Sustainable Development Goals. By engaging cities, we can build momentum around bottom-up interconnected actions and accelerate societal and technological transitions.

The temperature increase that occurs during running of a polymer gear pair can be divided into two components: the nominal and flash temperatures. The latter denotes the short-term temperature increase that takes place during a gear meshing cycle. A thorough analysis of the flash temperature yields an insight into the heat dissipation process, which also determines the nominal temperature increase
