Ökad tillgänglighet med följsam logistik

Logistik är ett ämnesområde som får allt större betydelse i allt fler branscher. Logistik sägs ha initierats av Napoleon då han utförde militära insatser på 1800-talet. För att klara matförsörjningen för sina militärer och för att underhålla den utrustning som fördes med trupperna så var han tvungen att ta med smeder, kockar och andra hantverkare som kunde försörja trupperna med mat och återställa

'This Is The Hell That I Have Heard Of' : Some Dialectical Images in Fossil Fuel Fiction

How can the realities of global warming be made visible in literary texts? After the rise of 'cli-fi', it might be time to return to a trove of literature written long before the discoveries of climate science: fiction about fossil fuels. It is filled with premonitions of disasters, such as extreme heat and terrible storms. Focusing on two texts - Ghassan Kanafani's Men in the Sun and Joseph Conra

Analysis of slab heating characteristics in a reheating furnace

For a reheating furnace, an analysis of thermal efficiency depends on precise investigations of the combustion and flow characteristics inside a furnace. Especially, the flow field of the hot gas has significant influence on heating slabs. The slabs are heated up to the temperature over 1500. K, and then they are transported to the rolling mill. The heating efficiency is affected by many factors,

Managing agricultural change for biodiversity conservation in a Mediterranean upland

In Europe, land use changes follow public policies, and particularly the Common Agricultural Policy. To predict the effect of policies on agricultural practices, landscape, and ultimately biodiversity, requires understanding of the interactions between social, economic and ecological dynamics at regional scale. We studied by means of prospective scenarios the possible effects of agricultural chang

Modelling invasibility in endogenously oscillating tree populations : Timing of invasion matters

The timing of introduction of a new species into an ecosystem can be critical in determining the invasibility (i.e. the sensitivity to invasion) of a resident population. Here, we use an individual-based model to test how (1) the type of competition (symmetric versus asymmetric) and (2) seed masting influence the success of invasion by producing oscillatory dynamics in resident tree populations. W

Roller coaster loop shapes revisited

In 'Rollercoaster loop shapes', (Pendrill 2005 Phys. Educ. 40 517) the author started from the observation that although textbook loops are often circular, real rollercoaster loops are not. In this paper the mathematical description of various possible loop shapes, as well as their riding properties was discussed and also how a study of loop shapes can be used in physics education.

Liquid in accelerated motion

What happens to a liquid in a swing or a loop? Accelerated motions leadto effects that may seem surprising. Consider a liquid in a glass placed ona wooden triangle, in turn attached to a string and moving fast in circle a vertical plane. The surface of the water remains parallel to the bottom of the glass—and orthogonal to the string—as long as gravity and the tension in the string are the only fo

Municipal governance and sustainability : The role of local governments in promoting transitions

This research addresses local governance for building energy efficiency. In order to turn an increasingly proactive environmental policy agenda at subnational levels into practice, local governments experiment with new forms of governance. One important policy area in this regard is building energy use, often addressed through urban development projects. Such initiatives provide important insight

The rate of joint replacement in osteoarthritis depends on the patient's socioeconomic status : a cohort study of 71,380 patients

Background and purpose - Assessment of potential disparities in access to care is a vital part of achieving equity in health and healthcare. We have therefore studied the effect of socioeconomic status (SES) on the rates of knee and hip replacement due to osteoarthritis. Methods - This was a cohort study in Skåne, Sweden. We included all residents aged ≥ 35 years with consultations between 2004 an

Enhanced immune response to MMP3 stimulation in microglia expressing mutant huntingtin

Huntington's Disease (HD) is an inherited neurodegenerative disease caused by a polyglutamine expansion in the huntingtin protein. The YAC128 mouse model of HD expresses the full-length human huntingtin protein with 128 CAG repeats and replicates the phenotype and neurodegeneration that occur in HD. Several studies have implicated a role for neuroinflammation in HD pathogenesis. Studies on presymp

A toolbox to evaluate non-residential lighting and daylighting retrofit in practice

In the field of lighting and daylighting, standard monitoring procedures to assess the overall performance of retrofit projects are scarce. Nevertheless, access to monitored data is crucial in assessing whether daylighting or electric lighting systems deliver the expected performance in terms of cost-effectiveness, energy efficiency and lighting quality. In order to bridge this gap, a lighting ret

Airborne hyperspectral data predict Ellenberg indicator values for nutrient and moisture availability in dry grazed grasslands within a local agricultural landscape

Species-based ecological indices, such as Ellenberg indicators, reflect plant habitat preferences and can be used to describe local environment conditions. One disadvantage of using vegetation data as a substitute for environmental data is the fact that extensive floristic sampling can usually only be carried out at a plot scale within limited geographical areas. Remotely sensed data have the pote

Bivalirudin versus heparin in non-ST and ST-segment elevation myocardial infarction - A registry-based randomized clinical trial in the SWEDEHEART registry (the VALIDATE-SWEDEHEART trial)

Background The optimal anticoagulant for patients with acute coronary syndrome treated with percutaneous coronary intervention (PCI) has not been validated in current practice of radial approach and pretreatment with potent P2Y12 inhibitors. Several studies have indicated increased bleeding rate and, in some instances, even increased mortality by the routine use of heparin and glycoprotein IIb/III

Hållbarhetskriterier för biogas : En översyn av data och metoder

I Sverige är biodrivmedel befriade från energi- och koldioxidskatt förutsatt att drivmedlet uppfyller hållbarhetskriterierna i EU:s direktiv om främjande av användningen av energi från förnybara energikällor. Ett av kriterierna är att användningen av biodrivmedlet måste leda till minskade emissioner av växthusgaser jämfört med fossila bränslen. Utsläppsreduktionen ska beräknas på det sätt som ange
