Upprustning av vattenbottnar kan rädda ålen Många frågor står obesvarade när man pratar om ålen och dess komplexa livscykel, där ålen föds och leker i havet men växer upp i sötvatten runtom i Europa ända ner till Nordafrika. Dock vet vi svaret på frågan om huruvida dess bevarandestatus ser ut idag: ålen är akut utrotningshotad och är på väg att dö ut, och den behöver hjälp för att överleva. ÅlbeAnthropogenic activities have caused aquatic habitats both indirect and direct damage, where loss of benthic substrates may consequently decrease the possibility of aquatic organisms surviving within affected areas. Restoration measures with introduction of suitable bottom substrates might thus create better opportunities for aquatic species to thrive within targeted locations, including endangere

En prognos för Skanör-Falsterbos kust Populärvetenskaplig text för: Dynerosion vid kraftiga stormar i Skanör-Falsterbo – simulering med hjälp av modellen XBeach Författare: Mikael Dunér och Axel Flodin Vacher Introduktion Diskussionen om hur vi ska bevara våra kuster och dess närmiljö, har växt allt mer i takt med att vi börjat se följderna av klimatförändringen.

As the Union Customs Code will replace the Community Customs Code with effect from 1 May 2016, the thesis focuses on the new treatment of royalty payments for customs purposes and its legal consequences. In a first step, a comparison between the Community Customs Code and the Union Customs Code reveals that importers will have to face a significant increase in the customs liability of royalty pa

Rätten till nödvärn är en av de ansvarsfrihetsgrunder som rättfärdigar en annars brottsbelagd gärning. För att nödvärn ska föreligga måste nödvärnshandlingen inte vara uppenbart oförsvarlig samt och det måste föreligga en nödvärnssituation. I denna försvarlighetsbedömning granskas angreppets beskaffenhet, det angripnas betydelse och omständigheterna i övrigt. Andra faktorer som kan påverka bedömniThe right to self-defence is one of the few ways to render an otherwise illegal action legal. The right to self-defence can only be given if the action taken by the attacked was not clearly unjustifiable and the situation calls for self-defence, according to the situations given in first paragraph in the 24 chapter of the Swedish Penal Code. In the assessment of whether or not the act is clearly u

Om ett brott som hör under allmänt åtal har begåtts ska förundersökning inledas och bedrivas i syfte att ta fram material som gör det möjligt för åklagaren att fatta beslut i åtalsfrågan. Till sin hjälp att bedriva en effektiv utredning har polis och åklagare möjlighet att använda straffprocessuella tvångsmedel. De straffprocessuella tvångsmedlen ger polis och åklagare rätt att använda åtgärder soIf an offense subject to public prosecution has been committed a preliminary investigation shall be initiated and carried out in order to optain materials to make it possible for the prosecutor to decide on the prosecution issue. To assist the police and prosecutors to conduct an effective investigationt they have the option of using coercive measures. The coercive measures give police and prosecu

Allteftersom företag har börjat att ompröva sättet de designar, tillverkar och avyttrar produkter inom ramarna för hållbar utveckling så har tillverkare av akustiska produkter varit långsamma ur startblocken. Majoriteten av akustiska produkter är fortfarande primärt sammansatta av nyråvara från petrokemiska resurser, vilka har en signifikant påverkan på miljön. Det är problematiskt ur både en miljAs industries have begun to rethink the way they design, make and dispose of products for the purpose of sustainable development, manufacturers of acoustic products have been slow off the mark. The majority of acoustic products are still made of primarily virgin material made from petrochemical resources, which have a significant impact on the environment. This is problematic from an environmental

Cytochrome c oxidases - why you need copper to breathe The next time anyone will ask you to provide any proof of evolution, you can surprise them by mentioning cytochrome c oxidases. Not only this answer will make you look smart and knowledgeable, but it will also provide a very solid example of something that brings together any oxygen-breathing organism, from the smallest bacterium to a majesti

Recent advances in the digital detector technology have paved the way for modalities such as two-dimensional digital mammography (DM) and three-dimensional breast tomosynthesis (BT). In this work, experimental studies were conducted to investigate the influence of reducing the average glandular dose (AGD) on detection of simulated lesions in DM and to compare the diagnostic accuracy of BT and DM.

The effects of dryer fabric cooling were studied. Using a dryer fabric cooled to a temperature below the dew point of the air-vapour mixture resulted in condensation of water vapour in the fabric structure. This condensation process was studied by means of a small-scale dynamic pilot dryer. The novel model on mass and heat transport in dryer fabrics, described in part 1, was validated against expe

Disposable electrodes were fabricated by coating chromium (5 nm) and gold (200 nm) on glass strips (5.0 mm x 25.4 mm) and used in a label-free immunosensor. Human Serum albumin (HSA) and its antigen (anti-HSA) were used as a model system. Electropolymerization of o-phenylenediamine was used for the immobilization of anti-HSA by covalent binding. A linear relationship was obtained in the range from

In this study pause patterns during writing were investigated and compared in a developmental perspective. The material consisted of keystroke logging recordings of the writing process of 30 expository texts written by 30 persons from the age groups 13-year-olds, 15-year-olds and 17-year-olds. A total number of 3080, all pauses longer than two seconds, were identified and categorized, according to

It is increasingly recognized that feelings of incompleteness and not just right experiences are important emotional and sensory processes underpinning obsessive-compulsive disorder (OCD). Such experiences refer to uncomfortable sensations that something is not right or not in its proper order, and they are typically accompanied by urges to perform behavioral or mental actions until it feels just

In many civil engineering problems, soil is stabilized by a combination of binders and water. The success of stabilization is evaluated using seismic tests with measured P-wave velocities. Optimization of process, laboratory testing and data modelling are essential to reduce the costs of the industrial projects. This paper reports the optimized workflow of soil stabilization through evaluated effe

The threat to the rural heritage has since the 1990s become a concern for Chinesescholars and heritage experts. Today many individual buildings and whole villageshave been listed as protected sites at different levels. But long before experts began totake an interest, villagers were themselves actively involved in protecting their owntraditions and the buildings of importance to the community (in

Visual abilities of the honey bee have been studied for more than 100 years, recently revealing unexpectedly sophisticated cognitive skills rivalling those of vertebrates. However, the physiological limits of the honey bee eye have been largely unaddressed and only studied in an unnatural, dark state. Using a bright display and intracellular recordings, we here systematically investigated the angu

In the Netherlands, the role of the woman in society has changed drastically in the past century. Furthermore, over the past 50 years, marriage between man and woman lost its dominant position to alternative forms of cohabitation. These developments in society and civil law are also reflect-ed in the Dutch Personal Income Tax Act (PITA) and the Dutch Gift and Inheritance Tax Act (GITA) and will be

The development of the intraovarian adrenergic nervous system was investigated in the guinea-pig by use of chemical determination of catecholamines with high performance liquid chromatography (HPLC) and with the formaldehyde-induced fluorescence method for visualization of adrenergic nerves (Falck-Hillarp technique). Ovaries from fetuses (39-40, 45-50, 55-57, 60-63 days of gestation) and young ani
