The existence of doubly charged Higgs bosons (H±±) is predicted by several theories beyond the Standard Model that aim to explain the origin of neutrino masses. These particles are expected to decay into same-sign lepton pairs H±± → ℓ±ℓ±. At the LHC, they are produced predominantly via the Drell–Yan process, resulting in four-lepton final states. Due to the rarity of events involving doubly charge

Two different main concepts for the treatment of a severe traumatic brain injury have been established during the last 15 years, namely the more conventional concept recommended in well-established guidelines (eg, U.S. Guideline, European Guideline, Addelbrook's Guideline from Cambridge), on the one hand, and the Lund concept from the University Hospital of Lund, Sweden, on the other. Owing to the

The earlier studies in this measurement series defined the limits and aims for design process to create better ventilating helmets [1], and tested the insulation [2] and evaporative characteristics [3] of the designed mock-ups. In addition some of the tested mock-ups were modified to study more closely the factors that were expected to improve heat transfer from the bicycle helmets. The present pa

When biomass is used to produce fuels and green products by thermochemical conversion, the ability to handle or remove the fine particle phase in the product gas is crucial. The product gas from biomass gasification contains relatively volatile organic compounds (“tar”) condensed on nonvolatile cores of, for example, aggregated soot particles and char. The problems are, for example, that particles

Analytic expression for the exact bit error probability of the (7,5) convolutional code was discussed. Recursive systematic encodes which became especially important as component encoders in concatenated coding schemes were also studied. This technique can calculate the probability distribution of the output log-likelihood ratios of the Max-Log-MAP algorithm in analytic form.

In the development of new food products, more knowledge is needed about the occurrence and quantity of food-borne pathogens in the food chain to be able to implement effective control measures and assure food safety. In addition, improved understanding of how environmental factors and food preservatives effect the microbial virulence expression in foods will enable the formulation of new strategie

In addition to being a key criterion of the sustainable development proviso, for business, the integration of social- and ecological considerations into decision-making is of growing importance for minimising future environmentally-related risk and associated economic costs, as well as gaining a share in growing markets favouring products and companies focusing upon social responsibility and ecolo

In an era of lifelong learning, empowerment of the learner becomes fundamental. Therefore ex-ploitation of the full potential of learning objects depends upon creation of an appropriate infra-structure to promote symmetrical control of inquiry. The learner needs to be empowered because learning is a discovery process and thus must be under his or her own control. In early stages of education it

Popular Abstract in Swedish Patienten med underbensamputation på grund av kärlsjukdom Långt före Kristi födelse var amputation av benet en känd operation. Anledningen till amputationen kunde vara kärlsjukdom, olycksfall, tumör eller medfödda missbildningar. I västvärlden idag utförs 90 % av amputationerna på grund av kärlsjukdom. Dessa patienter är äldre och sjukare än övriga benamputerade och meThe patient with unilateral trans-tribal amputation for vascular disease. Functional assessments, prognostic factors and cost of prostheses. The aims of the study were to focus on the functional ability of the dysvascular patient with unilateral trans-tibial amputation and the early rehabilitation period, defined here as the period between the amputation and the prosthetic fitting. Results revea

Potential doubling time (Tpot), DNA synthesis time (TS), and labelling index (LI) are fundamental growth kinetics parameters in clinical and experimental cancer research, which may be of further practical importance regarding prognosis and treatment prediction of cancer. They can be measured by bromodeoxyuridine(BrdUrd)/flow cytometry (FCM) methods, where BrdUrd, an analogue of thymidine, is incor

Prediction of the in-plane biaxial strength of paper by the Tsai-Wu failure criterion has in general proved to be in good agreement with experimental data. However, the Tsai-Wu criterion overestimates the strength in some parts of the biaxial tension region. This shortcoming can be corrected by adding a pair of cubic terms to the existing Tsai-Wu criterion. The modified Tsai-Wu criterion presented

Indolyl substituted pyranyl- and cyclohexenyl molybdenum complexes were synthesised through stereoselective nucleophilic addition of indoles to the corresponding cationic 2H-pyran or cyclohexadiene molybdenum complex. Decomplexation of an allylic molybdneum complex by treatment with iodine gave 1-(4-iodo-2-cyclohexenyl)-1H-indole-3-carbonitrile in high regio-selectivity. A new method for preparati

Abstract in UndeterminedThe report is an evaluation of five years of Linnaeus-Palme exchange programme between the chemistry departments at University of Gothenburg, Sweden and University of the West Indies, Jamaica. The exchange programme gives students and teachers at the two universities the possibility to study and teach at the partner university to better understand the international implicat
