Due to the high level of pollutant emissions from traditional marine diesel engines, Liquefied Natural Gas (LNG) as clean energy is becoming a better choice for main engines to replace the traditional fuels. Meanwhile, in order to improve the energy efficiency of the marine power system, the Organic Rankine Cycle (ORC) has been regarded as the most suitable solution to recover the waste heat for t

Key points• Obsessive-compulsive disorder is a disabling mental disorder with a lifetime prevalence of around 2% with similar rates across age groups and countries.• Diagnosis is made based on a pattern of time-consuming, clinically distressing, or impairing obsessions and compulsions and most cases emerge during puberty or early adulthood.• Obsessions are recurrent, persistent, and intrusive thou

A useful protocol for achieving decarboxylative cross-coupling (DCC) of redox-active esters (RAE, isolated or generated in situ) and halo(hetero)arenes is reported. This pragmatically focused study employs a unique Ag–Ni electrocatalytic platform to overcome numerous limitations that have plagued this strategically powerful transformation. In its optimized form, coupling partners can be combined i

A concise and enantioselective total synthesis of the Veratrum alkaloid cyclopamine is disclosed. This highly convergent synthesis with a 16-step longest linear sequence (LLS) was enabled by a de novo synthesis of the trans-6,5-heterobicycle via a strain-inducing halocyclization process, a key Tsuji–Trost cyclization to construct the fully substituted, spirocyclic THF motif with exquisite diast

Abstract There is a pressing need, particularly in the field of drug discovery, for general methods that will enable direct coupling of tertiary alkyl fragments to (hetero)aryl halides. Herein a uniquely powerful and simple set of conditions for achieving this transformation with unparalleled generality and chemoselectivity is disclosed. This new protocol is placed in context with other recently rThere is a pressing need, particularly in the field of drug discovery, for general methods that will enable direct coupling of tertiary alkyl fragments to (hetero)aryl halides.

OBJECTIVES: To compare patient reported outcomes from before surgery to 52 weeks after surgery between individuals undergoing arthroscopic partial meniscectomy for traumatic meniscal tears and those for degenerative meniscal tears.DESIGN: Comparative prospective cohort study.SETTING: Four public orthopaedic departments in the Region of Southern Denmark. Participants were recruited between 1 Februa

Objectives: This study sought to examine the relationship between temperature at reperfusion and infarct size. Background: Hypothermia consistently reduces infarct size when administered prior to reperfusion in animal studies, however, clinical results have been inconsistent. Methods: We performed a patient-level pooled analysis from six randomized control trials of endovascular cooling during pri

This paper focuses on the interaction of reasons and argues that reasons for an action may transmit to the necessary means of that action. Analyzing exactly how this phenomenon may be captured by principles governing normative transmission has proved an intricate task in recent years. In this paper, I assess three formulations focusing on normative transmission and necessary means: Ought Necessity

Catchy slogans about tourism’s peace-promoting qualities abound—‘passport to peace’, ‘a vital force for peace’, and ‘the peace industry’, to name but a few. Yet, despite the critical scrutiny of the peace–tourism nexus in recent decades, its historical origins remain unexplored. This article traces the historical roots of the idea that tourism can help advance peace and international understanding

Ecosystem functioning depends on biodiversity at multiple trophic levels, yet relationships between multitrophic diversity and ecosystem multifunctionality have been poorly explored, with studies often focusing on individual trophic levels and functions and on specific ecosystem types. Here, we show that plant diversity can affect ecosystem functioning both directly and by affecting other trophic

This article takes a cognitive approach to natural concepts. The aim is to introduce criteria that are evaluated with respect to how they support the cognitive economy of humans when using concepts in reasoning and communicating with them. I first present the theory of conceptual spaces as a tool for expressing the criteria. Then I introduce the central idea that natural concepts correspond to con

Probabilistic life-cycle consequence (LCCon) analysis (e.g., assessment of repair costs, downtime, or casualties over an asset's service life) can enable optimal life-cycle management of critical assets under uncertainties. This can lead to effective risk-informed decision-making for future disaster management (i.e., risk mitigation and/or resilience-enhancing strategies/policies) implementation.

The low water flux and high production cost of ceramic membranes for vacuum membrane distillation (VMD) are among the factors limiting their feasibility for desalination applications. To address this challenge, highly permeable anodic alumina membranes were modified and evaluated for their properties in VMD using a highly permeable support. Owing to the nanostructures on its surface, the anodic al

This study proposes to determine the influence of ‘Environmental Knowledge’ (EK), ‘Altruism’ (Atr), ‘Consumer Confidence’ (CC) and constructs of ‘Theory of Planned Behaviour’ (TPB) like Attitude” (Atd), ‘Subjective Norm’ (Sub) and ‘Perceived behavioural control’ (Pbhc) on consumers’ intention to purchase ‘Green Apparel Products’ (GAPI). Moreover, the moderating effect of ‘Perceived Innovativeness’

BackgroundTo enable people with stroke to achieve an active everyday life under altered conditions, the development of self-management programs is essential to facilitate the process of change that individuals must undergo. To improve access to self-management, internet-based solutions have been proposed. The aim of this study was to evaluate the feasibility of a novel internet-based intervention,

Existentiella hot, inklusive hot mot jaget, samhället och planeten, förekommer genom hela livet och utgör en central del av den mänskliga erfarenheten. För att sammanföra kunskap och begrepp om hur människor kan hantera existentiella hot på ett adekvat sätt sammankallade vi en tvärvetenskaplig arbetsgrupp bestående av åtta forskare från fälten psykologi, systematisk teologi, praktisk teologi, reliExistential threats, including threats to the self, society, and the planet, are present throughout the lifespan and form a core element of the human experience. To consolidate knowledge and constructs about how people can adequately respond to existential threats, we convened an interdisciplinary working group, which consisted of eight researchers from the fields of psychology, systemic theology,
