Mild heat treatment of carrot slices as a pre-treatment for frozen storage was accomplished by exposure of slices to radiant heat to maximise thermal exposure of the cells at the surface while preserving the integrity of cells within the slices. Cell damage as a consequence of this treatment on texture was evaluated. Carrot slices treated for 7 s with radiant energy in the far-infrared region from
Since conflict prevention is a visionary strategy it has beer difficult to put it into practice. This article explores conflict prevention in practice as well as in theory. There have been several attempts by the international community to take a proactive rather than a reactive approach to conflict management. One case often held up as a model for post Cold War prevention is the preventive missio
We establish the local well-posedness for a recently derived model that combines the linear dispersion of Korteweg-de Veris equation with the nonlinear/nonlocal dispersion of the Camassa-Holm equation, and we prove that the equation has solutions that exist for indefinite times as well as solutions that blow up in finite time. We also derive an explosion criterion for the equation, and we give a s
In this article we report Si 2p core-level spectroscopy results from the alkali (Li, Na, and K) induced Si(111)-3 x 1 reconstructions. The experimental results are compared to the theoretical honeycomb-chain channel (HCC) model for,the 3 x 1 reconstruction using density functional theory (DFT) to calculate core-level shifts using both initial and final-state calculation schemes. Si 2p core-level s
Urinary hexahydrophthalic acid (HHP acid) levels were determined in 20 workers occupationally exposed to hexahydrophthalic anhydride (HHPA) air levels of 11-220 micrograms/m3. The levels of HHP acid in urine increased rapidly during exposure and the decreases were also rapid after the end of exposure. The elimination half-time of HHP acid was 5 h, which was significantly longer than in experimenta
Background & objectives: Human and animal cystatins have been shown to inhibit the replication of certain viruses and bacteria, though it is not directly demonstrated that the effects are due to protease inhibitory capacity of the cystatins. We report antibacterial properties of a novel antimicrobial peptidyl derivative, (2S)-2-(N-alpha-benzyloxycarbonyl-arginyl-leucylamido)-1-(E)-cinnamoyla m
The influence of different nutrient conditions on the production of toxins was studied in certain fishkilling haptophytes (e.g. Prymnesium parvum and Chrysochromulina polylepis). The toxicity was strongly influenced by the nutrient status of the medium, resulting in a significantly higher toxicity when grown under nutrient limited conditions compared to nutrient replete conditions. This occurred i
The water channel aquaporin-1 (AQP1) is considered as the molecular counterpart of the ultrasmall pore predicted by the three-pore model of fluid transport across the peritoneal membrane. However, the definitive proof of the implication of AQP1 in solute-free water transport, sodium sieving, and ultrafiltration (UF) during peritoneal dialysis (PD) is lacking, and the effects of its deletion on the
This paper is a direct continuation of a previous study that addressed the performance and design of a variable compression engine, the Alvar-Cycle Engine [1]. The earlier study was presented at the SAE International Conference and Exposition in Detroit during February 23- 26, 1998 as SAE paper 981027. In the present paper test results from a single cylinder prototype are reviewed and compared wit
The present study is a review of published investigations regarding the economy of ethanol production from lignocellulosic material The objective is to present relations between and tendencies observed in different cost estimates. The influence of plant capacity and overall product yield on the ethanol production cost is investigated, as well as variations in capital costs in the different process
Laparoscopic cholecystectomy (LC) is attempted in all our patients scheduled for cholecystectomy. The related standard radiologic procedures are preoperative ultrasonography (US) and preoperative cholangiography (PCA). In a retrospective study of 214 patients scheduled for LC over a 2-year period we have reviewed the radiologic and clinical records. Preoperative US revealed stones in the common bi
Popular Abstract in Swedish Genom att använda en fettsyra, oktansyra, som modelsubstans har fouling pga adsorption inne i membranmatrisen studerats. Det har visats att mycket lågmolekylära hydrofoba föreningar kan ha en förödande inverkan på ett membrans flux, även om retentionen för dem är mindre än 10%. En teori om att foulingen beror på kapillärkondensation och hur detta skulle kunna användas fA study of fouling of ultrafiltration membranes due to adsorption of a fatty acid in the membrane matrix has been done. Octanoic acid was used as a model substance. It has been shown that a low-molecular-weight hydrophobic solute can have detrimental effects on the flux of hydrophobic ultrafiltration membranes even though the size of the solute is much smaller than the cut-off of the membrane and
That the Church of Norway has now adopted gender equality as its policy, is a new situation in a historical perspective, and is the result of a long process within the framework of the state church system. In this context, the way in which the Storting (the Norwegian parliament) dealt with the issue of admitting women to clerical offices in the 1930s was important. The purpose of this thesis has b
