Background: Logistics and distribution of sold goods have traditionally been individually handled by each company in the Wanxingda Group with minimal coordination on group level. The strong relationships between the companies within the group and their close geographical proximity to each other indicate that there might exist potential for closer collaboration in this area. Furthermore, many of th
One of the biggest expenses for airline companies is the fuel for the aircrafts; preceded only by labor costs it is important for an airline to optimize its use of fuel. One option to save money on fuel is by doing something called Fuel Tankering. Essentially, fuel tankering is a way to lower the fuel cost by refueling at departures where the fuel price is lower than at the destination of the airc
The use of natural gas is increasing globally. At the same time, the cheap and easily accessible resources are decreasing rapidly. Among other alternative gases, biogas is considered since it is a renewable resource. In order for biogas to really become a large scale alternative, it needs to be fully compatible with today’s infrastructure and gas applications. This report is evaluating the technic
Rationale: Knowledge regarding the prevalence and shared and unique characteristics of the restrictive spirometric pattern (RSP) and preserved ratio impaired spirometry (PRISm) is lacking for a general population investigated with post-bronchodilator spirometry and computed tomography of the lungs. Objectives: To investigate shared and unique features for RSP and PRISm. Methods: In the Swedish CAr
In many species, polymorphic genomic inversions underlie complex phenotypic polymorphisms and facilitate local adaptation in the face of gene flow. Multiple polymorphic inversions can co-occur in a genome, but the prevalence, evolutionary significance, and limits to complexity of genomic inversion landscapes remain poorly understood. Here, we examine genome-wide genetic variation in one of Europe’
This study examines farmers' willingness to sell straw for energy and material applications in Scania, Sweden. Using interviews and surveys, we tested three empirical consequences derived from the premise that missing data on farmers' willingness to sell straw for energy may misrepresent the biomass supply in potential assessments. Findings reveal willingness to sell straw depends on end use, with
Background: Knee Osteoarthritis (KOA) is a heterogeneous pathology characterized by a complex and multifactorial nature. It has been hypothesised that these differences are due to the existence of underlying phenotypes representing different mechanisms of the disease. Methods: The aim of this study is to identify the current evidence for the existence of groups of variables which point towards the
Bacterial ice-nucleating particles (INP) have the ability to facilitate ice nucleation from super-cooled cloud droplets at temperatures just below the melting point. Bacterial INP have been detected in cloud water, precipitation, and dry air, hence they may have an impact on weather and climate. In modeling studies, the potential impact of bacteria on ice nucleation an
Northeast China, the most important region for commercial grain farming in China, is vulnerable to drought due to high fluctuation in monthly rainfall. Timely, accurate and effective drought monitoring is very essential for securing the output of grain farming. In this study, three widely used drought indices were compared using satellite soil moisture data and their capability for drought monitor
Aim: Parental care improves the survival of offspring and therefore has a major impact on reproductive success. It is increasingly recognized that coordinated biparental care is necessary to ensure the survival of offspring in hostile environments, but little is known about the influence of environmental fluctuations on parental cooperation. Assessing the impacts of environmental stochasticity, ho
Introduction: Developing a national assistive products list is an important part of an assistive technology policy and requires knowledge of total population need, and product costs and benefits; information is not always readily available in low-income countries. Our experience in Tajikistan of developing a national assistive products list provides guidance for others. Methods: Two hundred people
The present work details a study of the 3D-modeling of dual-fuel engines, with a specific focus on medium speed marine engines. These operate under the fumigated approach, which means that the second fuel, which replaces most of the diesel fuel, is added in the intake duct. This type of engine requires the least amount of modifications to the current medium speed diesel engine and is therefore an
Partially premixed combustion (PPC) is a promising way to achieve high thermal efficiency and low emissions, especially by using multiple injection strategies. The mechanisms behind PPC efficiency are still to be explained and explored. In this paper, multiple injections have been used to affect the gross indicated efficiency in an optical PPC engine modified from a Volvo MD13 heavy-duty diesel en
Background: Migraine is a debilitating neurological disorder where trigeminovascular activation plays a key role. We have previously reported that local application of Complete Freund’s Adjuvant (CFA) onto the dura mater caused activation in rat trigeminal ganglion (TG) which was abolished by a systemic administration of kynurenic acid (KYNA) derivate (SZR72). Here, we hypothesize that this activa
Host responses to parasitism in the wild are often studied in the context of single host–parasite systems, which provide little insight into the ecological dynamics of host–parasite interactions within a community. Here we characterized immune system responses to mostly low-intensity, chronic infection by haemosporidian parasites in a sample of 424 individuals of 22 avian host species from the sam
Objective: Little is known about midlife risk factors of future cardiac arrest. Our objective was to evaluate cardiovascular risk factors in midlife in relation to the risk of cardiac arrest (CA) of cardiac and non-cardiac origin later in life. Methods: We cross-matched individuals of the population based Malmö Diet and Cancer study (n = 30,447) with the local CA registry of the city of Malmö. Bas
Objectives: We have observed clinical cases where bone is formed in the overlaying muscle covering surgically created bone defects treated with a hydroxyapatite/calcium sulphate biomaterial. Our objective was to investigate the osteoinductive potential of the biomaterial and to determine if growth factors secreted from local bone cells induce osteoblastic differentiation of muscle cells.

With peroral levodopa treatment, a majority of patients develop motor fluctuations and dyskinesia already within a few years of therapy. Device-aided Parkinson (PD) therapies refer to deep brain stimulation (DBS), levodopa-carbidopa intestinal gel infusion (LCIG), and subcutaneous infusion of the dopamine agonist apomorphine and represent effective strategies counteracting motor fluctuations and d
Introduction: Resistance to antiretroviral drugs can complicate the management of HIV-1 infection and impair control of its spread. The aim of the current study was to investigate the prevalence and transmission of HIV-1 drug resistance among 106 antiretroviral therapy (ART)-naïve patients diagnosed in Iceland (1996–2012).Methods: HIV-1 polymerase sequences were analysed using the Calibrated Popul
The local geology at Kloxåsen is characterised by ejecta deposits from the 458 Ma Lockne marine impact. The Kloxåsen ejecta are located on a Caledonian parautochthonous unit, approximately 7 km from the centre of the 7.5-km-wide Lockne crater structure. The ejecta were deposited on the seafloor and were covered with seawater immediately after the impact event. Of special interest is a mafic impact
