Transient Control of Combustion Phasing and Lambda in a Six-Cylinder Port-Injected Natural-Gas Engine

Fuel economy and emissions are the two central parameters in heavy duty engines. High exhaust gas recirculation rates combined with turbocharging has been identified as a promising way to increase the maximum load and efficiency of heavy duty spark ignition engines. With stoichiometric conditions, a three way catalyst can be used, which keeps the regulated emissions at very low levels. The Lambda

Successful Selective Thrombolysis for Limb-Threatening Ischemia due to Bilateral Lower Extremity Emboli After Open Aortic Aneurysm Repair

Severe lower extremity emboli with occlusion of all 3 lower limb arteries bilaterally occurred after an elective open abdominal aortic aneurysm (AAA) repair. Selective thrombolysis with alteplase and repeated percutaneous transluminal angioplasty (PTA) along the occlusions on both side anterior and posterior tibial arteries was performed without complications. Angiography the following day showed

Sex-Specific Fitness Consequences of Nutrient Intake and the Evolvability of Diet Preferences

The acquisition of nutrients is fundamental for the maintenance of bodily functions, growth, and reproduction in animals. As a result, fitness can be maximized only when animals are able to direct their attention to foods that reflect their current nutritional needs. Despite significant literature documenting the fitness consequences of nutrient composition and preference, less is known about the

Doubly reactive INS-IGF2 autoantibodies in children with newly diagnosed autoimmune (type 1) diabetes.

The splice variant INS-IGF2 entails the preproinsulin signal peptide, the insulin B-chain, eight amino acids of the C-peptide and 138 unique amino acids from an ORF in the IGF2 gene. The aim was to determine whether levels of specific INS-IGF2 autoantibodies (INS-IGF2A) were related to age at diagnosis, islet autoantibodies, HLA-DQ, or both, in newly diagnosed type 1 diabetes patients and controls

Applying social sciences to inspire behavioural change in the construction sector: an experimental study

In several reports, the construction industry has been criticized for inefficiencies, errors and increasing costs. Although the industry's critics and researchers implicitly call for a change in human behaviour, this is seldom explicitly problematized by any of them. It is rather seen as a natural consequence of the suggested measures for improvements. Researchers have begun to question if the inf

EANM procedure guideline for the treatment of liver cancer and liver metastases with intra-arterial radioactive compounds

surgery (i.e. resection or liver transplantation), but only 10-20% of patients are candidates for this. In other patients, a variety of palliative treatments can be given, such as chemoembolization, radiofrequency ablation or recentlyPrimary liver cancers (i.e. hepatocellular carcinoma or cholangiocarcinoma) are worldwide some of the most frequent cancers, with rapidly fatal liver failure in a lar

Multinational Firms, Acquisitions, and Job Tasks

We revisit the question how inward FDI and multinational ownership affect relative labor demand. Motivated by the recent literature that distinguish between skills and tasks, we argue that the impact of multinational and foreign ownership on the demand for labor is better captured by focusing on job tasks rather than education. We use Swedish matched employer-employee data and find that changes of

Thrombospondin-4 knockout in hypertension protects small artery endothelial function but induces aortic aneurysms.

Thrombospondin-4 (TSP-4) is a multidomain calcium-binding protein that has both intracellular and extracellular functions. As an extracellular matrix protein it is involved in remodeling processes. Previous work showed that in the cardiovascular system, TSP-4 expression is induced in the heart in response to experimental pressure overload and infarction injury. Intracellularly, it mediates the end

Atomoxetine's Effect on Societal Costs in Sweden

Objective: To compare societal costs between patients treated with atomoxetine and placebo in Sweden. Method: Ninety-nine pediatric ADHD patients were randomized to a 10-week double-blind treatment with atomoxetine (n = 49) or placebo (n = 50). All parents received four sessions of psycho-education. Parents filled out a resource utilization questionnaire covering the 10 weeks prior to treatment an

Trait-dependent responses of flower-visiting insects to distance to semi-natural grasslands and landscape heterogeneity

Protecting semi-natural grasslands may through spill-over benefit species richness and abundance of flower-visiting insects in linear habitats, such as uncultivated field boundaries, in agricultural landscapes. However, whether local diversity increases both with decreasing distance from potential source habitats and increasing landscape heterogeneity is poorly known due to a general lack of studi

Development of a pressure-measuring device to optimize compression treatment of lymphedema and evaluation of change in garment pressure with simulated wear and tear.

The use of compression garments in treating lymphedema following treatment of genital (penis, testes, uterus, cervical) and breast cancer treatment is a well-established practice. Although compression garments are classified in compression classes, little is known about the actual subgarment pressure exerted along the extremity. The aims of this study were to establish an in vitro method for measu

General overview: European Integrated project on Aerosol Cloud Climate and Air Quality interactions (EUCAARI) - integrating aerosol research from nano to global scales

In this paper we describe and summarize the main achievements of the European Aerosol Cloud Climate and Air Quality Interactions project (EUCAARI). EUCAARI started on 1 January 2007 and ended on 31 December 2010 leaving a rich legacy including: (a) a comprehensive database with a year of observations of the physical, chemical and optical properties of aerosol particles over Europe, (b) comprehensi

Comparative proteomic analysis of hyphae and germinating cysts of Phytophthora pisi and Phytophthora sojae.

The recently described oomycete pathogen Phytophthora pisi causes root rot on pea and faba bean, while the closely related Phytophthora sojae is the causal agent of soybean root and stem rot. Differences in the pathogenicity factor repertoires that enable the two species to have distinct host specificity towards pea and soybean, were studied using tandem mass spectrometry in a global proteome stud

SDI planning using the system dynamics technique within a community of practice: lessons learnt from Tanzania

There exist major challenges in accelerating the spatial data infrastructure (SDI) planning process in the developing countries as well as advocating for politicians to support the development of SDI, due to the high complexity of SDI, lack of knowledge and experience, and limited insight in the benefits. To address these challenges, a methodology for SDI planning in Tanzania, based on the system

A cathodoluminescence study of the influence of the seed particle preparation method on the optical properties of GaAs nanowires.

Cathodoluminescence at 8 K is used to compare the optical properties of AlGaAs-capped GaAs nanowires, grown by metal-organic vapour phase epitaxy and seeded by gold particles prepared by different methods. Six different methods were used to fabricate and deposit gold seed particles onto GaAs substrates: colloid particles, aerosol particles and particles defined by electron beam lithography. The na

A massive expansion of effector genes underlies gall-formation in the wheat pest Mayetiola destructor

Gall-forming arthropods are highly specialized herbivores that, in combination with their hosts, produce extended phenotypes with unique morphologies [1]. Many are economically important, and others have improved our understanding of ecology and adaptive radiation [2]. However, the mechanisms that these arthropods use to induce plant galls are poorly understood. We sequenced the genome of the Hess
