Humans are poorly adapted for underwater vision. In air, the curved corneal surface accounts for two-thirds of the eye's refractive power, and this is lost when air is replaced by water [1]. Despite this, some tribes of sea gypsies in Southeast Asia live off the sea, and the children collect food from the sea floor without the use of visual aids [2]. This is a remarkable feat when one considers th
In this paper we consider a 1-warehouse, N-retailer inventory system where demand occurs at all locations. We introduce an inventory model which allows us to set different service levels for retailers and direct customer demand at the warehouse. For each retailer a critical level is defined, such that a retailer replenishment order is delivered from warehouse stock if and only if the stock level e
High-spin states of T-z = 1 nuclei were studied with the reactions Ni-58(Si-28,3 alpha)Kr-74,Ni-58(Si-28,2 alpha)Sr-78, and Ni-58(Si-28,2p2n)Zr-82 at 130 MeV beam energy. The Gammasphere array in conjunction with the 4 pi charged-particle detector array Microball was used to detect gamma rays in coincidence with evaporated light charged particles. The known pi = +, alpha = 0 yrast bands were exten
Uppmärksamheten rörande flyktingfrågan tenderar att beröra människor på olika sätt. Det kan få dess effekter på gott och ont. Jag har valt att koncentrera mig på en mer påtvingad invandring som jag väljer att kalla det. Den påtvingade aspekten på det menar jag är människors flykt från dess hemländer, vilket får de att bli flyktingar av olika slag. Jag diskuterar där de olika grunder som kan bli akThe attention regarding the refugee issue tends to affect people in different directions. It has its effect in both a good and bad way. I have chosen to concentrate on what i call a forced migration. The forced aspect in this subject is those people fleeing from their respective homelands, which ends up resulting in that these people become refugees of different kind. I will discuss the bases whic
Signal is a very important part of the railway. If you place a signal or a different object which is also important in the wrong place, can mean increased safety risks. To ease the work of the consultants in the creation of operational site drawings, the aim is to develop an action plan for the creation of a database, which in turn will be used to create a tool that can be used to automate the pro
Jönköping stad har stora framtidsambitioner och hoppas på att staden kan växa i samband med att den nya höghastighetsjärnvägen byggs. För att klara av nya invånare och uppnå de kommunala och transportpolitiska målen behöver kollektivtrafiken byggas ut. Den nuvarande busslinje 1 som är den mest trafikerade linjen i Jönköping idag behöver dras om vid vissa delar för att inkludera den nya höghastigheJönköping city has big ambitions for its future, and they hope that the city can grow with the new highspeed railway. To manage all the new citizens and make up for the communal and transport political goals they need to expand their community rides. Today’s bus line 1, which is the most trafficked line in Jönköping, need a reroute to include the new station for the highspeed trains which will be
This thesis examines the nature and purpose of the Greek sciences ἀριθμητική, λογιστική and γεωμετρία in the texts of Plato. The statements of some other ancient authors are also mentioned, and the relevant modern research is consulted. ἀριθμός is at any instance, as Klein has already noted, ‘a definite number of definite objects’. In Plato’s philosophical ἀριθμητική, ἀριθμός seems to always consi
The use of biofuel has been used a long time and its consumption keeps increasing. Depending on where the fuel comes from, the chemical composition can be very different. There have been incidents of ashes generating flammable gases, but also the ashes itself have been seen in dust explosion incidents. The risk must be understood and evaluated properly. This paper aims to investigate how explosive
Systems development methods mirror different organizational perspectives, and not all methods are formalised, but what they have in common is the purpose of structuring and supporting systems development processes. Which method would be the most suitable may be determined by the systems development context at hand, because every systems development context is unique. Information is a valuable asse
In this essay I will look at the independence of the Swedish municipalities. By looking at articles for the biggest journal in Sweden on this subject Kommun aktuellt I will look at the discussion for the years of 1978 and 1998 to see if one can draw some parallels in the debate and see if some subjects are always returning in the agenda for the independence. The autonomy of the Swedish municipalit
The purpose of the study was to examine how mothers from 30 to 35 years living in a big city felt that stress and status affects their everyday lives and health. My questions was how mothers feel and handling requirements in relation to family life and parenting versus career, the demands on the mothers themselves, and how mothers look at the link between stress and status? I wanted to explore the
Populärvetenskaplig sammanfattning: Malmö ur ett mandelblomsperspektiv. Tänk dig att du är en mandelblom på en äng någonstans i trakterna kring Malmö. I början av Maj år 1802 kryper du upp ur jorden och känner solens strålar mot dina blad. Du sätter blommor, du får frön som av en vindpust förs iväg och landar i en hage inte så långt bort. Nu låtsas vi att ditt frö inte gror, utan det ligger kvar iBiodiversity preservation has a high priority in nature conservation on a global, regional and local scale. The rate at which species are extinct today is very high and this is to a large extent a consequence of human influence on the earth’s ecosystems. The decreasing biodiversity in Sweden is mainly an effect of the landscape becoming more fragmented. GIS is generally considered as an effective
Den underkambriska lagerföljden i Skandinavien utgörs huvudsakligen av ljusa, marint avsatta sandstenar och når i Skåne en mäktighet av ca 120 meter. Två borrkärnor från Skryllebrottet i västra Skåne undersöktes och dokumenterades med avseende på petrografiska egenskaper och mineralinnehåll, samt diagenetiska egenskaper och bakomliggande processer. Lagerföljderna, som representerar hela HardebergaThe Lower Cambrian of Scandinavia consists mainly of light-coloured marine sandstones, with thicknesses reaching approximately 120 m in Skåne (Scania). Two drill cores from the Skrylle Quarry of west-central Skåne were investigated and documented with respect to their petrographic properties, mineral contents, and diagenetic history. The drill cores are divided into three lithofacies, and represen
