The shell condenser is one of the key components of underwater vehicles. To study its thermal performance and to design a more efficient structure, a computational model is generated to simulate condensation inside straight and helical channels. The model combines empirical correlations and a MATLAB-based iterative algorithm. The vapor quality is used as a sign of the degree of condensation. Three

Microbial carbon use efficiency (CUE), or the partitioning of assimilated C into growth or respiration, is a key parameter that is central to understanding the soil C cycle and its feedback to environmental and climate change. The availability of nitrogen (N), organic matter (OM) quality and environmental factors influence CUE indirectly by affecting growth rates and respiration of the major micro

The aim of this paper is to explore, conceptualize, and critically discuss how the temporary retail site of the pop-up store works towards inciting consumers to buy products which have previously been discarded. Drawing on, and developing, the concept of the retailscape, we use empirical material from an ethnographic study to show how the temporal retailscape of the pop-up store is assembled, and

A numerical method was used to study the effect of clearance and rotational number on the thermal performance in a detached latticework duct. The latticework duct, which had four-entry sub-channels, was located in a simplified rectangular channel. The crossing angle for each sub-channel was 45°. The numerical studies were conducted with various clearances (0–0.5) and various rotational numbers (0–

Industries and regional economies evolve as a result of the interplay between local and non-local factors. Increasing globalization of both production- and innovation activities implies a shift in the relevant scales of interaction from the local towards the global level. This paper is concerned with the implications of such scale shifts for the role of the region and for cluster-related regional

This study evaluates the potential of supervised and transfer learning techniques to assist energy system optimization. A surrogate model is developed with the support of a supervised learning technique (by using artificial neural network) in order to bypass computationally intensive Actual Engineering Model (AEM). Eight different neural network architectures are considered in the process of devel

In a technologically dependent society, like the one we are living in today, it is of importance to develop citizens' technological literacy, including an understanding of technological processes and technological systems and the ability to make informed decisions. Technology is a compulsory subject in Swedish compulsory school. The curriculum requirements include the abilities to identify, analys

Objective: To study the association between the level of Cesarean hysterotomy and the presence of large uterine scar defects 6–9 months after delivery. Methods: This was a two-center, randomized, single-blind trial of a surgical procedure with masked assessment of the principal outcome under study. Women without a history of Cesarean section (CS) who underwent emergency CS at cervical dilatation ≥

OBJECTIVE To investigate real-world costs of continuous insulin pump therapy compared with multiple daily injection (MDI) therapy for type 1 diabetes. RESEARCH DESIGN AND METHODS Individuals with type 1 diabetes and pump therapy in the Swedish National Diabetes Register (NDR) since 2002 were eligible. Control subjects on MDI were matched 2:1 using time-varying propensity scores. Longitudinal data

Banknotes and their design play an important role in creating a nation’s identity.This paper analyzes the design of German, French and Italian banknotes in the period after the formation of national states in the 19th century until the outbreak of World War II. We take into account the economic development of these countries and relate it to banknote issuance. Our analysis reveals that the banknot

In the aftermath of the global financial crisis, increasing attention has been paid to the role played by financial factors in business cycle fluctuations. The crisis also led to the development of economic policies, beyond traditional microprudential regulation, that promote financial stability. Macroprudential policy is one such tool. It fosters a more resilient financial system by directly tack
