The price of fish depends on quality attributes such as size and freshness. In turn, quality attributes are related to fishery management. This article presents a hedonic analysis where attribute prices of size and quality ratings are estimated for the Swedish Baltic cod fishery. Using information from 5,307 landing days, hedonic inverse demand functions are estimated with a random coefficient (RC
The problems of allocation of scarce resources and priority setting in health care have so far not been much studied in the context of stem cell-based therapeutic applications. If and when competitive cost-effective stem cell-based therapies are available, the problem of priority setting - to whom should stem cell-based therapies be offered and on what grounds - is discussed in this article using
Development and application of some laser techniques for the study of engine combustion are presented. The investigations mainly cover two aspects: fuel dynamics and formation of NO. Fuel dynamics is one of the most central problems in engine design since many performance parameters are affected by it; emission formation, efficiency, drivability etc. The studies include cycle-resolved measurement
This article presents two new models that give a perspective on green chemistry (GC). The first model is a classification model of different green chemistry activities, while the second model concerns green chemistry policy and knowledge areas (green chemistry principles, industrial biotechnology and "the green sector"). A broad view of green chemistry is used, where all activities with the aim of
The distribution of mRNA for pituitary adenylate cyclase-activating polypeptide (PACAP) type 1 (PAC1) and vasoactive intestinal polypeptide (VIP) types 1 and 2 (VPAC1 and VPAC2, respectively) receptors was examined by reverse transcriptase polymerase chain reaction (RT-PCR) in human cerebral arteries and in trigeminal, otic, sphenopalatine and superior cervical ganglia. RT-PCR products of the expe
Human aquaporin 2 (AQP2) is a water channel found in the kidney collecting duct, where it plays a key role in concentrating urine. Water reabsorption is regulated by AQP2 trafficking between intracellular storage vesicles and the apical membrane. This process is tightly controlled by the pituitary hormone arginine vasopressin and defective trafficking results in nephrogenic diabetes insipidus (NDI
Contemporary advancements in miniaturization of analytical systems have advantageously fostered development, automation, and hyphenation of a variety of sample preparation techniques. Among several downscaled extraction designs, porous synthetic polymeric membranes (such as flat sheet (FS) or hollow fiber (HF)) have been utilized for membrane-based extraction, separating two aqueous phases (as in
Popular Abstract in Swedish Förbränning av fossila bränslen som bensin, kol, olja och naturgas orsakar att koldioxid ackumuleras i atmosfären, vilket är en av orsakerna till global uppvärmning. Transportsektorn står för största delen av Sveriges användning av bensin och olja. Oljan är importerad från andra länder, som gör oss väldigt beroende av omvärlden. Ett av de mest lovande alternativa bränslTransportation fuels from renewable resources such as ethanol are one of the alternatives to ensure energy security and decrease the net emission of carbon dioxide. First-generation ethanol production from sugar- and starch-based raw materials (1G) is today well established in many countries, and the focus of research has thus shifted to the development and demonstration of the production of secon
Studies of natural radiative lifetimes and hyperfine structure have been performed for group IIA and IIIA atoms. Different laser spectroscopic techniques such as PUMOLS, time-resolved laser spectroscopy, using transient recorder, and collimated atomic-beam experiments have been used. These methods employ cw or pulsed dye laser systems. The lifetime measurements revealed several cases in barium and
Pile heat exchangers are fast emerging as a potentially viable alternative to the more prevalent borehole heat exchangers for the provision of space heating and cooling. In the last decade or so, the use of geothermal piles has increased sharply in many countries including Belgium, China, Japan, Switzerland, the Netherlands, United Kingdom, and United States, among others. In Sweden, however, inte
Vertigo is one of the most common complaints in medicine. Despite its high prevalence, patients with vertigo often receive either inappropriate or inadequate treatment. The most important reasons for this deplorable situation are insufficient interdisciplinary cooperation, nonexistent standards in diagnostics and therapy, the relatively rare translations of basic science findings to clinical appli
