This paper is concerned with the management of multi-plant manufacturing networks. Two key concepts in this domain are plant roles and plant autonomy in the context of operations strategy decision-making. We investigate the relationship between these two concepts and their impact on plant performance. We use data from 102 manufacturing plants belonging to multi-plant networks. The results suggest
In this paper we present a technique that improves rendering performance for real-time ith ray in the presence of dynamic lights and objects. In particular we verify photon paths from the previous frame against dynamic objects in the current frame, and show how most photon paths are still valid. When using area lights, we use a data structure to store light distribution that tracks light paths all
This study aims to understand how goals of activation and gender equality interact in labor market programs directed towards activating unemployed participants. The study draws on interviews with 28 social workers and managers at four Swedish municipally governed labor market programs typically targeted towards poor, unemployed individuals with little to no attachment to the labor market or social
This paper presents the numerical study of soot formation and oxidation processes across different ambient temperatures (900K, 1000K, and 1100K) and oxygen levels (15% and 21% O2) using large eddy simulation coupled with a two-equation soot model. The predicted ignition delay time, lift-off length and soot distribution show good agreements with the corresponding experimental data. A stronger oxida
Background: Deep Brain Stimulation (DBS) is an established treatment for motor symptoms in Parkinson's disease (PD). However, side effects often limit the usefulness of the treatment. New method: To mitigate this problem, we developed a novel cluster of ultrathin platinum-iridium microelectrodes (n = 16) embedded in a needle shaped gelatin vehicle. In an established rodent PD-model (6-OHDA unilate
Diffusion MRI (dMRI) can probe the tissue microstructure but suffers from low signal-to-noise ratio (SNR) whenever high resolution is combined with high diffusion encoding strengths. Low SNR leads to poor precision as well as poor accuracy of the diffusion-weighted signal; the latter is caused by the rectified noise floor and can be observed as a positive bias in magnitude signal. Super-resolution
Welding fumes induce lung toxicity and are carcinogenic to humans but the molecular mechanisms have yet to be clarified. The aim of this study was to evaluate the toxicity of stainless and mild steel particles generated via gas–metal arc welding using primary human small airway epithelial cells (hSAEC) and ToxTracker reporter murine stem cells, which track activation of six cancer-related pathways
Quinoa (Chenopodium Quinoa Willd.), a South American grain, has great potential for innovation and development of improved food products because of its protein content and nutritional benefits. The study aimed to develop an instant-mix beverage based on fermented quinoa with reduced phytate content and viable lactic bacteria. Two different lactic fermentation processes were designed known as Ferme
To counteract global food safety hazards related to raw consumption of ready-to-eat leafy vegetables, a method to improve bacterial status using antagonistic bacteria was studied under field conditions. This is the first study to identify potential Escherichia coli antagonists from the native microbiota on leafy green vegetables and evaluate their effect in an industrial field production setting.
This brief overview of the use of household salt (NaCl) in optically stimulated luminescence (OSL) dosimetry is focusing on the use of NaCl pellets. It is suggested that the most optimal use of household NaCl, in general prospective dosimetry, is to compress the salt grains to pellets and read the radiation induced signal using OSL rather than TL. A summary of the main OSL dosimetric properties is
Recent interest in applying novel imaging techniques to infer optical resolution in compound eyes underscores the difficulty of obtaining direct measures of acuity. A widely used technique exploits the principal pseudopupil, a dark spot on the eye surface representing the ommatidial gaze direction and the number of detector units (ommatidia) viewing that gaze direction. However, dark-pigmented eye
The learning with errors (LWE) problem is one of the main mathematical foundations of post-quantum cryptography. One of the main groups of algorithms for solving LWE is the Blum–Kalai–Wasserman (BKW) algorithm. This paper presents new improvements of BKW-style algorithms for solving LWE instances. We target minimum concrete complexity, and we introduce a new reduction step where we partially reduc
The gut bacterium Prevotella copri (P. copri) has been shown to lower blood glucose levels in mice as well as in healthy humans, and is a promising candidate for a next generation probiotic aiming at prevention or treatment of obesity and type 2 diabetes. In this study the hypoglycemic effect of live P. copri was confirmed in mice and pasteurization of P. copri was shown to further enhance its cap

In this report, the effectiveness of a detector-activated water mist system, Q-fog, has been compared to traditional residential sprinklers. In total, eight tests were performed with a realistic fuel (bed with pillow and duvet) based on the test procedure described in LPS 1655. The bed was placed at different locations in the room and was ignited at the pillow and below the bed, also according to In this report, the effectiveness of a detector-activated water mist system, Q-fog, has been compared to traditional residential sprinklers.

What is the potential role of degrowth and buen vivir in addressing underdevelopment and conflict in the Global South? Underdevelopment and conflict are often portrayed as the most important challenges for countries in the Global South. Not only are they important, but they are also related; the level of development is seen to present an indication for the risk of violent conflict and civil war. P
The Sustainable Development Goals outline a “shared blueprint for peace and prosperity for people and the planet, now and into the future”. However, this is not only ambitious; there appear to be inherent contradictions to reconciling the economic, environmental, and social goals. Goal 16 on Peace, Justice and Strong Institutions relies on the promotion of “sustainable development” to achieve envi
Vad hände med innebörden av ordet "otrygghet", ett ord med gamla svenska rötter och en tidigare etablerad innebörd, när det amerikanska forskningsfältet "Fear of Crime" introducerade i Sverige och översattes till "Otrygghet"? Syftet med denna avhandling är att beskriva trygghetsforskningens uppkomst, etablering och expansion i Sverige, i syfte att besvara frågor om forskningsdiskursens funktion, sThe purpose of this dissertation is to construct an historical account of the emergence, establishment, and expansion of fear of crime research in Sweden. This dissertation aims to answer questions about the function, spread, and high level of institutional engagement of fear of crime research by analyzing the literature and examining the methodological, theoretical, and epistemological origins of
Synthetic pheromones have been used for pest control over several decades. The conventional synthesis of di-unsaturated pheromone compounds is usually complex and costly. Camelina (Camelina sativa) has emerged as an ideal, non-food biotech oilseed platform for production of oils with modified fatty acid compositions. We used Camelina as a plant factory to produce mono- and di-unsaturated C12 chain
