In the last decades, emission legislation on pollutant emissions generated by road transportation sector has become the main driving force for internal combustion engine development. Approximately 20% of worldwide emissions of carbon dioxide from fuel combustion come from the transportation sector, and road vehicles contribute up to 80% of those emissions [1].Light-duty methane gas engines are usuIn the last decades, emission legislation on pollutant emissions generated by road transportation sector has become the main driving force for internal combustion engine development.

Paperboard mechanical properties at fracture during uniaxial tests is an interplay between available elastic energy at fracture and the fracture energy needed to separate the sample into two parts. In a test at a critical specimen length, the load vs. elongation curve immediately drops from a point of instability to zero load, whereas a test at a stable length gives a stable descending load-elonga

ObjectivesThe objective of our article is to show how “quality of evidence” and “imprecision,” as they are defined in Grading of Recommendations Assessment, Development, and Evaluation (GRADE) articles, may lead to confusion. We focus only on the context of systematic reviews.Study Design and SettingWe analyze, with the aid of standard probabilistic and statistical concepts, the concepts of qualitThe objective of our article is to show how “quality of evidence” and “imprecision,” as they are defined in Grading of Recommendations Assessment, Development, and Evaluation (GRADE) articles, may lead to confusion.

Introduction: Complicated perianal disease (cPD) may be the sole presentation of Crohn’s disease (CD). The role of small-bowel capsule endoscopy (SBCE) in the diagnostic algorithm of cPD is unclear. We aimed to evaluate the role of SBCE as a diagnostic tool, in patients with cPD, after a negative standard workup for CD. Methods: A multicenter, retrospective, cross-sectional study, in patients with

Ekonomisk-historiska institutionen har ett välgrundat rykte för sina omfattande forskningsprogram med tonvikt på långsiktiga processer, baserad på ekonomisk teori och med kvantitativa metoder som viktiga verktyg. Forskningsämnena är inriktade på frågor av hög relevans för samhället. Institutionens forskare genererar årligen en imponerande mängd internationell publicering och är mycket framgångsrThe Department of Economic History has a well-established reputation for wide-ranging research programmes with an emphasis on long-term processes, based on economic theory and quantitative methods as important tools. The research topics are oriented towards issues of high relevance for society. The Department has an acknowledged international publication record and is very successful at attracting

With the increasing focus on reducing emissions and making fuel efficient vehicles within the automotive industry over the past few years, new methods are constantly being investigated to improve the efficiency of the powertrain. One such method is recovering waste heat from the exhaust gases as well as the coolant using a thermodynamic cycle such as a Rankine cycle. However, most studies looking

Atherosclerosis is a disease characterized by chronic inflammation and fibrosis of the intima of large and medium sized arteries. Atherosclerosis in the coronary arteries is the most common cause of myocardial infarction and atherosclerosis in the carotids and other major arteries supplying the brain is the major cause of stroke. Cardiovascular diseases caused by atherosclerosis is the most common
