Modifying Cooking Practices to Reduce the Formation of Heterocyclic Amines

Popular Abstract in Swedish Vid tillagning av kött, och framför allt stekning och grillning, bildas mutagena ämnen i stekskorpan. Dessa ämnen benämns heterocykliska aminer. Flera epidemiologiska studier har visat ett samband mellan uppkomsten av cancer och intaget av heterocykliska aminer, medan några studier inte finner något samband. Ämnena har också visat kunna utveckla tumörer och cancer i djuCommonly cooked meat dishes contain heterocyclic amines (HAs) at ng/g levels. HAs are animal carcinogens, form DNA adducts in human tissues, and have been associated with increased risk of cancer in epidemiological studies, and it is thus recommended that human intake be decreased. The aim of this investigation was to find ways of modifying cooking practices to reduce the formation of HAs. Various

Age-related circulatory responses to whole body cooling: observations by ballistocardiographic EMFi sensors

The purpose was to study age related changes in circulatory system via Ballistocardiography (BCG) by utilizing Electromechanical Film (EMFi) sensors by gradually changing the ambient temperature from a thermoneutral area to cold direction. ECG and BCG were recorded from a young person (23 years) and from an older person (78 years), both males. During the tests, brachium blood pressure (BP) and pul

Lexical inferencing procedures in L3 Italian

This study is aimed at investigating and describing the different procedures of foreign language learners of Italian when they infer the meaning of unknown words in a written authentic text. Vocabulary is a crucial component in the learning process of a foreign language and many studies show that lexical inferencing is one of the most important strategies when foreign language learners encounter u

Shards of Iron Age Communications. A ceramological study of internal structures and external contacts in the Gudme-Lundeborg Area, Funen during the Late Roman Iron Age

Popular Abstract in Swedish Målet för ceramologisk forskning är att studera och beskriva keramikhantverkstraditioner : krukmakarna, deras produktion och sociala organisation samt användningen af keramikprodukterna. Kunskapen om keramiken gör det möjligt också att studera de mänskliga handlingarna, som keramiken tog del i. Den föreliggande avhandlingen söker att avtäcka kontakt-mönstre mellan olikaThe objective of ceramology is to describe pottery craft traditions; the potters, their production, social organisation and the use of the products. Through this the human actions surrounding the pottery are studied. The objective of the research presented in this thesis is to study patterns of contacts between different, contemporary sites within a limited area through a ceramological analysis of

Tool Life and Wear Modelling in Metal Cutting, Part 2 ─ Based on Combining the Archard and the Colding Equations

In this article an analytical and empirical model for describing tool life and tool wear in metal cutting is presented. The model is based on combining the Colding tool life equation and an extended version of the Archard wear function. It is shown that through the combining of these two models a substantial saving of resources can be achieved in terms of the workpiece material required, as well a

Some Acoustic Cues to Human and Machine Estimation of Speaker Age

Two experiments were carried out in order to learn more about the relation between the various acoustic cues to speaker age. The first included listening tests with resynthesized stimuli, and the second comprised automatic estimation of age using the CART (Classification And Regression Trees) technique. In the first experiment, results indicate that human listeners seem to rely more on spectral cu

Taxation of Dividend Income and Economic Growth: The Case of Europe

More recently researchers have turned to analyze how the tax structure, rather than the overall tax level, affects economic performance. For instance, several papers have investigated how taxation on corporate and individual (labor) income influences growth. Taxation of dividend income may also influence growth via its impact on investments and firm behavior. Within the academic community there is

Molecularly Imprinted Polymers at the Nanometric Scale: Synthetic Receptors for Chemical Sensors

In this thesis, polymerisation techniques or deposition methods have been developed permitting the creation of thin molecularly imprinted polymer (MIP) films or patterns and their interfacing with transducer surfaces for biosensor applications. The creation of ultra thin films has been achieved using two different techniques, spin-coating and in-situ polymerization of thin films of monomers conta

Populärvetenskapligt skrivande som mål och medel

Kan populärvetenskapligt skrivande bidra till en bättre ämnesförståelse? Kan det bidra till att öka kvaliteten även på det vetenskapliga skrivandet? Vilken roll spelar lärarens eller handledarens återkoppling under skrivprocessen för lärandet? Hur kan populärvetenskaplig kommunikation integreras i utbildningen? Detta är några av de frågor som denna rundabordsdiskussion kommer att utgå ifrån. Syfte

High-Resolution Measurement of the 4He(g,n) Reaction in the Giant Resonance Region

Popular Abstract in Swedish Kärnan kan ses som en samling nukleoner vilka hålls samman av den starka kraften. Nukleonerna är protoner (p) med laddning +1 och neutroner (n) med laddning 0. Kraften kan beskrivas som ett utbyte av mesoner såsom pioner (pi) vilka förekommer i tre laddningstillstånd pi+, pi- och pi0 (laddning +1, -1 och 0). Inuti kärnan rör sig nukleonerna och utbytesmesonerna vilket gA comprehensive near-threshold 4He(g,n) absolute cross section measurement has been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 20 < Eg < 45 MeV tagged photons (covering the Giant Dipole Resonance energy region) were directed towards a liquid 4He target, and knocked-out neutrons were detected in a pair of 60 cm x 60 cm vetoed NE213A liquid scintilla
