Kvinnan:mannen::alternativet:normen ett feministiskt perspektiv på klassifikation
Using a feministic perspective and a critical approach, my purpose is to discuss bibliographic classification, a central aspect of Library and Information Science. More specifically, my aim is to demonstrate the norms and the dominating thoughts regarding the organization and representation of knowledge, subjects, and social categories in classification systems. I review previous research involving critical approaches to classification. These show that classification systems are a reflection of the context in which they are created, with the result that universal assumptions can be questioned. Some studies also present problems inherent in hierarchical structures.
Elektromagnetisk och mekanisk design av en 20MW turbogenerator
At the Division of Electricity at UppsalaUniversitythere are ongoing researches, including a research concerning turbo generators.Turbo generators produce a large share of electricity in the world; however they are costly mainly due to the fact that the cooling and ventilation that are needed to eliminate the excess heat from the generators are expensive. Turbo generators work with high efficiency and in this project, the main task is to simulate a generator while taking into account that the generator must be designed against self-oscillation, centrifugal force, exhaustion and heat. The turbo generator must be simulated without being too expensive and complicated.In this project, the dimensions of the turbo generator depend on the efficiency of it, and where the losses are in the generator. Furthermore, the optimum values need to be chosen with the help of the ACE simulation program. The report begins with an introduction describing the project followed by a task description that is dealing with the project.
Skillnader mellan katalogiseringsregler för ljudupptagningar: En fråga om syften och principer?
The aim of this thesis is to describe and compare the cataloguing rules for sound recordings: the rules used by a specialised archive and common libraries respectively. We will put the rules in relation to purposes (the objectives of a bibliographic system) and principles (directives that guide the construction of a bibliographic language). The first question to be answered is in which way the set of rules used by a specialised archive differ from the one used by common libraries. The second question examines if and how the differences can be derived from purposes and principles. The sets of rules studied are KRS (chapter 6) and the Swedish version of the IASA Cataloguing Rules (1999), worked out by the National Archive of Sound and Moving Images (SLBA).
Rostfärgat slam i dränagesystem vid vattenkraftsanläggningar : orsaker och åtgärder
From embankment dams is something that has long been noticed and given rise to different questions. The most serious question is if the sludge is a result of inner erosion through the dam, and thus consists of material transported from the dam. Concerns have also been raised whether the sludge could interfere with the systems drainage capacity and thereby lead to high pore pressure in the dam, or if the measurement of seepage is disturbed, as the measuring is usually made via Thomson weirs, which could risk being blocked.
The result of this investigation shows that the sludge is a result of the oxidation of iron by iron bacteria, and to the greater part consists of these oxides as well as the bacteria?s own structures. The iron oxidizing bacteria, FeOB, oxides ferrous iron to ferric as a part of their metabolism, and thereby create large quantities of iron(oxy)hydroxides.
Arenans betydelse för en stad : En studie av en arenas tillförande av väde i platsmarknadsföring
AbstractThe purpose with this essay has been to gain a greater understanding and clarify how an arena can create value within place marketing and development of a place brand. This will be achieved through a description of which values an arena causes in the surrounding areas and an understanding of how these values can be interpreted through the place brand. We decided to base our study according to the following two questions:1. What are the underlying reasons why there has been such a big trend with arena project?2.
Metadata enligt Dublin Core : Tillämpningar och konsekvenser i de svenska kvalitetssöktjänsterna SAFARI, Svenska miljönätet och Svesök
This study investigates the individual usage of the Dublin Core metadata format in three Swedish Subject Based Information Gateways, SAFARI, Svenska miljönätet and Svesök. The authors also present the reader with an overview of the metadata concept and explains in particular the Dublin Core Element Set. The approach to the study is investigation of Dublin Core application from the viewpoint of three major issues, user friendliness, interoperability and quality control. The study includes an in-depth comparison of the three different metadata templates, as well as interviews with people in charge of the metadata production at the respective SBIGs and users of the respective SBIGs« templates. The study shows that the three SBIGs are more similar than they are different.
Museum på webben - en undersökning om användbarhet och åtkomst
The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems.
Eutanasi : en skonsam död
This work is about euthanasia and how to use it on horses, dogs and cats.
A description for each animal is done, about when it is time, why, which methods can be used and who is allowed to use them, how and where it shall be done.
The methods we have concentrated on are:
- Chemical destruction and the most common drugs for euthanatize horses, dogs and cats.
- Physical disruption of the brain activity by a captive bolt, only for horses.
The captive bolt only makes the horse unconscious and must always be followed by cutting off the vena jugularis. Then the horse dies because of loss of blood.
No matter which method used for euthanizing, the animal must be declared to be dead by the operator before other measures. The testing criteria for death: muscle relaxation and cyanosis, cessation of reflex activity and pupillary dilatation, cessation of respiratory activity and cessation of all cardiac activity.
Vaddå matematiksvårigheter : En studie utifrån elevens perspektiv om svårigheter och kritiska moment vid lärandet i matematik
This paper investigates how students in the humanities in four universities in Sweden reflect on their education and the current view on the humanities as an education and a science. I want to investigate what impact the past few years public debate about the humanities have had on the students. What kind of beliefs and identities do the students of the humanities form and how do they discuss the universities, the choices they made in life and how do they feel about the future.This study is based on interviews with seventeen students in Sweden from four different universities. The research is also based upon a report that The Confederation of Swedish Enterprise (Svenskt Näringsliv) published in 2011 and the debate following that report. I have also made participant observations on the four universities to make a broader description for the reader.
