A continuous-review two-echelon inventory system with one central warehouse and a number of nonidentical retailers is considered. The retailers face independent Poisson demand and apply standard (R, Q) policies. The retailer order quantities are fixed integer multiples of a certain batch size, representing the smallest pallet or container size transported in the system. A warehouse order may consi
The Universal Thermal Climate Index (UTCI) aimed for a one-dimensional quantity adequately reflecting the human physiological reaction to the multi-dimensionally defined actual outdoor thermal environment. The human reaction was simulated by the UTCI-Fiala multi-node model of human thermoregulation, which was integrated with an adaptive clothing model. Following the concept of an equivalent temper
Akademisk teori såväl som politiska diskussioner framhåller ofta entreprenörskap som gynnsamt för ekonomisk tillväxt. De specifika teoretiska mekanismerna som gör att entreprenörskap leder till tillväxt har dock inte kunnat fastslås och det är därför inte klart om entreprenörskap alltid är ekonomiskt gynnsamt, och för vem? I denna artikel kommer vi att sammanfatta den empiriska forskningen inom en
Background: B-vitamins are essential for one-carbon metabolism and have been linked to colorectal cancer. Although associations with folate have frequently been studied, studies on other plasma vitamins B2, B6, and B12 and colorectal cancer are scarce or inconclusive. Methods: We carried out a nested case-control study within the European Prospective Investigation into Cancer and Nutrition, includ
Background: The Patient Enablement Instrument (PEI), which has been used to evaluate core ingredients in primary care consultations, has been proposed as a means of moving beyond patient satisfaction evaluations. The aim of the present study was to examine the reliability and applicability of the PEI to the Swedish context. Methods: The original PEI was translated to Swedish and included in a ques
This special section of an issue of Science and Public Policy grew out of an interest in following the politics of the European Spallation Source (ESS) Facility at Lund, Sweden. The ESS spectacle provided a platform from which to review different research infrastructure projects and to place them in the context of science policy as a whole. Large-scale research infrastructure investments are often
Context. It is still debated whether or not the Galactic chemical evolution of sulphur in the halo follows the flat trend with [Fe/H] that is ascribed to the result of explosive nucleosynthesis in type II SNe. It has been suggested that the disagreement between different investigations of sulphur abundances in halo stars might be owing to problems with the diagnostics used, that a new production s
Understanding how learning occurs, and what improves or impedes the learning process is of importance to academicians and practitioners; however, empirical research on validating learning curves is sparse. This paper contributes to this line of research by collecting and analyzing CAD (computer-aided design) procedural and cognitive performance data for novice trainees during 16-weeks of training.
Popular Abstract in Swedish Hemofili A är en form av blödarsjuka som beror på en medfödd defekt av äggviteämnet faktor VIII (FVIII). FVIII spelar en viktig roll för att kroppens blodlevringsförmåga (s.k. koagulation) ska fungera optimalt och med nedsatt funktion hos FVIII riskerar man att drabbas av allvarliga blödningar i framför allt leder, men även i muskler, slemhinnor (t.ex. näsblödning) och Haemophilia A (HA) is caused by defective synthesis of coagulation factor VIII(FVIII), which has serious effects on haemostasis; joints being the most common site of bleeding. The development of FVIII replacements has improved the situation for patients with haemophilia such that chronic arthropathy can be prevented, and life expectancy and the quality of life have increased. However, approximatel
Objective: To describe a multidisciplinary program, given by an occupational therapist and a physiotherapist, for patients with stress-related disease in primary health care and to measure the effect of this program in terms of self-perceived health, degree of burnout, physical activity, symptoms, recreational activities, and psychological and physical well-being. Method: Retrospective study. Re
The effects of wood ash application on soil microbial processes were investigated in three drained forested peatlands, which differed in nutrient status and time since application. Measured variables included the concentrations of soil elements and phospholipid fatty acids (PLFAs), net nitrogen (N) mineralization, nitrification and denitrification enzyme activity, potential methane (CH(4)) oxidati
Five new monophyletic groups of xanthorioid lichens have been identified by phylogenetic analyses using nuclear ITS and 18S and mitochondrial 12 mt and 23 mt sequences. As a consequence, the following new genera are described: Gallowayella, Jesmurraya, Honeggeria, Massjukiella and Martinjahnsia. New combinations for 26 species are proposed: Gallowayella aphrodites, G. borealis, G. concinna, G. cop
Background: Previous studies have focused on weight maintenance following weight loss, i.e. secondary weight maintenance (SWM). The long-term results of SWM have been rather modest and it has been suggested that preventing initial weight gain, i.e. primary weight maintenance (PWM), may be more successful. Therefore, developing a prevention strategy focused on PWM, enabling normal weight or overwei
Background: Overweight and obesity during pregnancy raise the risk of gestational diabetes and birth complications. Lifestyle factors like physical activity may decrease these risks through beneficial effects on glucose homeostasis. Here we examined physical activity patterns and their relationships with measures of glucose homeostasis in late pregnancy compared to non-pregnant women. Methods: Nor
Background: Older patients generally have only poor knowledge about their medicines. Knowledge is important for good adherence and for participating in decisions about treatment. Patients are entitled to be informed on an individual and adequate level. The aim of the study was to explore frail elderly patients' experiences of receiving information about their medications and their views on how the
The aim of the European Funded Project BRAFO (benefit-risk analysis of foods) project was to develop a framework that allows quantitative comparison of human health risks and benefits of foods based on a common scale of measurement. This publication describes the application of the BRAFO methodology to three different case studies: the formation of acrylamide in potato and cereal based products, t
The low field ESR lineshape and the electron spin-lattice relaxation correlation function are calculated using the stochastic Liouville theory for an effective electron spin quantum number S = 1. When an axially symmetric permanent zero field splitting provides the dominant relaxation mechanism, and when it is much larger than the rotational diffusion constant, it is shown that both electron spin
We present a protocol for a facile orientation specific deposition of plate-like mesoporous SBA-15 silica particles onto a surface (mesopores oriented normal to surface). A drop of an aqueous dispersion of particles is placed on the surface and water vaporizes under controlled relative humidity. Three requirements are essential for uniform coverage: particle dispersion should not contain aggregate
