From Grain to Feed

Horse beans are used as an example of grain, which have potentials to substitute fish meal in fish feed. After several grinding and fractionation steps it was possible to obtain a protein-rich horse bean fraction with a yield of 19 %. This fraction contained 55.9 % protein. The high protein content together with the amino acid profile makes the fraction very suitable as a substitute to fish meal in fish feed. The protein-rich fraction was used as a successful additive in extruded fish pellets

Surface Patterns – Surface Law

 On my almost daily bicycle rides in the mornings of the spring and early summer 2013 I began noticing the presence of several women wearing trousers with large printed patterns. I wondered whether this might indicate a certain shift from the dominant modern mono-chromatic norm regarding Nordic / Danish women’s urban (summer) dress. To what extent are fashion norms influencing and interacting with other social and societal norms including, what has in the Western world long been called legal norms – most often understood as state produced norms

Heuristic Solution Approaches to the Double TSP with Multiple Stacks

This paper introduces the Double Travelling Salesman Problem with Multiple Stacks and presents three different metaheuristic approaches to its solution. The Double TSP with Multiple Stacks is concerned with determining the shortest route performing pickups and deliveries in two separated networks (one for pickups and one for deliveries) using only one container. Repacking is not allowed, instead each item can be positioned in one of several rows in the container, such that each row can be considered a LIFO stack, but no mutual constraints exist between the rows. Two different neighbourhood structures are developed for the problem and used with each of the heuristics. Finally some computational results are given along with lower bounds on the objective value.

Effects of Cultivation Conditions for Apples on Growth Rates of Fruit Fly Larvae and Contents of Phenolics

Apples were grown with 3 different alleyway groundcover management strategies, providing a wide range of nutrient availabilities to the trees, spanning the ranges normally found in both conventional and organic orchards. These treatments had significant effects on both yields and incidence of fungal diseases. However, the differences in yields and disease incidence cancelled each other out, resulting in identical average yields of marketable fruit, as reported earlier (Lindhard Petersen & Bertelsen 2002). These results indicated that the composition of the fruit may also differ, and that this material is useful as a model for investigating how growth conditions influence the content of nutritionally relevant compounds, and thus may affect the health of humans and animals. In a preliminary study, two species of fruit flies were reared on material from each of the 3 cultivation treatments, and the time when 50% of the flies in each vial had emerged was calculated. Development duration, hours Treatment: Annual clovergrass Perennial clovergrass Perennial grass (high N availability) (medium N availability) (low N availability) Species: D. melanogaster: 256 271 286 Drosophila hydei: 456 475 557 The fruit from each treatment, as well as corresponding fruit treated with pesticides, was analysed for contents of phenolic compounds. The number of flies produced in each treatment did not differ systematically, but observations indicate that the fastest development also resulted in the heaviest animals. It should be pointed out that excessive growth rates (obesity) is a major health risk in affluent human societies. This material is also used in ongoing rat feeding experiments
