Experiments on dry face turning offunctionallygraded heat treatable steel are conducted. The workpieces have a hardened zone of approx. 60 HRC and a non-hardened zone of approx. 30 HRC. PCBN tools are used with different feeds, cutting speeds and depths of cut. Measurements of residual stresses in the surface layer reveal compressive stresses in the hardened zone and tensile stresses in the non-ha
In modern industrialised society prepared meals and eating out of home is an increasing phenomenon. This develops new business opportunities for food manufacturers, since they need to create more convenience to the consumers through food that can be prepared and served quickly. However, the new food products require increased quality and safety and thereby more controlled distribution. The issue i
Scholarship of Teaching and Learning (SoTL) is discussed as a strategy for institutional improvement of teaching and learning. Engagement in SoTL could be an individual enterprise focusing external networks including conference presentations and journal publications. This strategy could lead to development and improved teaching for the individual but not necessarily contribute to the developme
In TSP with neighborhoods (TSPN) we are given a collec-tion X of k polygonal regions, called neighborhoods, with totally n ver-tices, and we seek the shortest tour that visits each neighborhood. TheEuclidean TSP is a special case of the TSPN problem, so TSPN is alsoNP-hard. In this paper we present a simple and fast algorithm that, givena start point, computes a TSPN tour of length O(log k) times
Planning and implementing an open-loop, business-wide national pool system for transport packaging (trays and pallets) is a complex process. This research project is focusing on the driving forces in the development and decision processes. During 1992-1999, a group of logistics specialists within the Swedish food supply chains took part in a development process, which included much learning and ne
We present a flexible and efficient program package written in C++, PROFASI, for simulating protein folding and aggregation. The systems are modeled using an all-atom description of the protein chains with only torsional degrees of freedom, and implicit water. The program package has a modular structure that makes the interaction potential easy to modify. The currently implemented potential is abl
This thesis concerns two interrelated subjects of heat and mass transfer processes. The first one concerns mainly experimental measurements, with a subsequent development of a calculation procedure, of the thermal and hydraulic performances, experimental methods and evaluation procedures applied on various plate heat exchangers (PHEs) as evaporators with the refrigerant ammonia as working medium.
Women are a neglected group for cardiovascular disease. Whereas young women tend to have lower incidences of coronary artery disease, stroke and myocardial infarctions than men, the situation changes drastically at menopause, after which women are at greater risk than men. Despite this, women at all ages receive less treatment, less attention and not enough information about health risks. Most ris
We propose a new third-order multidimensional upwind algorithm for the solution of the flow equations on tetrahedral cells unstructured grids. This algorithm has a compact stencil (cell-based computations) and uses a finite element idea when computing the residual over the cell to achieve its third-order (spatial) accuracy. The construction of the new scheme is presented. The asymptotic accuracy f
Particle separation is one of the fundamental processes in wastewater treatment and a good understanding of the basic separation mechanisms ? sedimentation, flotation and filtration ? is critical in the design of wastewater treatment systems. Upgrading of treatment plants for enhanced primary treatment and effluent polishing are current examples of applications where effective, high-rate separatio
Swedish legislation and international norms emphasize society's obligation to ensure general accessibility. The possibility of independent outdoor mobility, transportation, and travel are as important for individuals with reduced functional capacity as for other members of society, but today their mobility is limited. The aim of this article is to outline a novel field for research collaboration b
We study the complexity of the dynamic partial sum problem in the cell-probe model. We give the model access to nondeterministic queries and prove that the problem remains hard. We give the model access to the right answer +/-1 as an oracle and prove that the problem remains hard. This suggests which kind of information is hard to maintain. From these results, we derive a number of lower bounds fo
Objective Incidence of cardiovascular disease (CVD) is higher in men than in women. The aim of this study was to investigate whether the gender differential can be modified by pharmacological intervention in a population-based setting. Design and method In a prospective population-based cohort - the Malmo Diet and Cancer study - a total of 3608 hypertensives (1559 men, 2049 women), 45-73 years old
Recent marsupials include about 280 species divided into 18 families and seven orders. Approximately 200 species live in Australia/New Guinea. The remaining species inhabit South America with some of these secondarily ranging into North America. In this study, we examine marsupial relationships and estimate their divergences times using complete mitochondrial (mt) genomes. The sampling, which incl
Results from large scale, ab initio MCHF calculations are presented for the transition properties of the 3s2 3p2(3)P(J-)e{3s3p3, 3s2 3p3d, 3s2 3p4s} 5S2o and 3P2o intercombination and resonance lines in P II. The agreement with experiment is good, the systematic approach shows convergence and the agreement between different forms of the oscillator strength is excellent for the resonance lines.
