Urinseparerande avloppssystem - En utvärdering med hänsyn till teknik, ekonomi, användbarhet och drifterfarenhet
This paper deals with the use of Internet at Swedish public libraries. The author asks whether public libraries should or should not limit access to information available on the Internet. Starting from the American discussion, concerning Internet at public libraries, the author shows the Swedish attitudes. The paper demonstrates that many Swedish public libraries have adopted rules forbidding retrieval of certain kinds of information, such as hard-core pornography and racist propaganda. The persons in charge of such actions claim that public libraries should provide high-quality educational literature and should not spread mass-produced, provocative information.
Är förekomst av knäckesjuka i tallföryngringar mindre på stora naturvårdsaspar än på aspsly?
Pine twisting rust (Melampsora pinitorqua) is a parasitic rust fungus found all across Sweden causing damage resulting in lower quality and reduced tree growth in pine stands. In Sweden, the fungus is dependent on two alternate hosts; European aspen (Populus tremula) and Scots pine (Pinus sylvestris). Pine twisting rust has five different spore stages, two of them (uredinio- and teliospores) on the leaves of aspen. Injures on aspen caused by pine twisting rust is not extensive. On the other hand, when it infects the annual shoots of Scots pine it often results in a bent steam or even a top shoot breakage.
En elev som till slut exploderar : En vetenskaplig essä om praktisk kunskap vid problemskapande beteende
This scientific essay starts in a story where you get to follow me in my work by three situations with creative problem behavior at the special school where I work. The story culminates in a dilemma where I ask myself questions about how I look at my actions and my thoughts about the student. I break down and put these thoughts into three questions: What is my student's perspective and how will it affect my actions? How can I explain my actions and attitude of the student from ethical perspective? How do my practical knowledge look like in the narrative situations and why do I act like I do?My approach is to get answers to the questions by the reflection of the text itself, the reflection group and supervisors, as well as through literature that I find relevant to the issues. The process is like a pendulum motion between text, reflection and new understanding.I look at my situations based on psychological theories about the treatment of persons within the autism spectrum of problems creative behavior.
Konsumentinformation i förändring - Samarbete mellan Stockholms kommunala konsumentvägledning och Stockholms stadsbibliotek
Voluntary organisations provided the first consumer guidance in Sweden. The government'sinterest in the question started during the second world war and has ever since increased.Since the 1970's the local authorities, with support from the community, have played animportant roll in consumer policy work. Due to the economic recession of recent years theappropriation to consumer guidance work has been cut down. The work has been rationalisedand libraries have more frequently been used to spread consumer information.In Stockholm the municipal has been responsible for local consumer information since the1940's. Co-operation with the library of Stockholm has occurred in different forms.

Hjärtfrekvensvariabilitet hos friska hundar
In healthy dogs, heart rate fluctuates during the day. Heart rate variability (HRV) reflects the autonomic nervous system´s regulation of the cardiovascular unit. Heart rate variability shows the balance between the sympathetic and parasympathetic nervous system, also called sympathovagal balance. Heart rate variability can be measured by time domain - and frequency domain analysis. In a time domain analysis you study the beat-to-beat-interval (RR-interval) in an electrocardiogram (ECG), while a frequency domain analysis can be used to determine the size of the variability.
Underlag för en pedagogisk turled i permakulturekobyn Suderbyn
Permaculture is a design system that aims at developing sustainable human settlements and self-maintained agriculture; it may also be used for community planning. The design system of permaculture aims at mimicking a natural ecosystem; this gives the advantage to make use of all the connections and mechanisms that exist in such a system.The purpose of this bachelor thesis was to compile and spread scientific information regarding five different themes within the areas of ecology, environmental science and permaculture. This was achieved through cooperation with the permaculture inspired Ecovillage Suberbyn in southern Gotland. Information about the central parts of a permaculture ecovillage was used as material for a series of signposts that will be located around the ecovillage Suderbyn. The five selected themes were: An overview of permaculture, The forest garden, The pond, Composting and The use of human excrement and urine..
Magnetfält alstrade kring nätstationer i samband med lokaldistribution av elkraft : Magnetic fields generated by electrical substations during distribution of electric power
Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.The report deals with a number of formulated questions and/or hypothesis? stated at the onset of the work undertaken, theory that is relevant for the topics the report covers, the details of the field work undertaken and the following analysis of the readings, which in term provide answers for the questions stated in the beginning. It also covers what is the currently known short term and long term risks associated with electromagnetic fields in the power frequent spectrum and of varying intensity in the vicinity of humans.The analysis also provides recommendations and identifies several points to carefully consider when planning for new installations or replacements of some parts of existing installations.For enhanced reading comprehension there is, aside from sections with pictures and attached explanatory texts and templates, several graphs, one-line diagram and maps of the power grid among the appendixes to the rapport..
Museernas roll i samhället : En intervjustudie av Stockholms stadsmuseum, Länsmuseet Gävleborg och Världskulturmuseet
This is a two year master's thesis in the field of museum and cultural heritage studies. The purpose of the thesis is to examine different opinions among museum employees about the role of museums. The thesis also aims to find out to what extent and in what way these opinions are influenced by the museum's own policy documents, the national cultural policy and the academic field of museum studies. I have conducted qualitative research interviews with six employees from three different cultural history museums. The theoretical framework of the thesis is based on Laruajane Smith's term authorized heritage discourse.
Musik som hjälpmedel för att öka aptiten hos äldre
It has long been discussed how to use music in a new way in the field of food and elderly, and in this study, the authors wanted to test this. Music is the language of emotions. It?s a powerful tool, but its effects are difficult to predict (Theorell, 2009). Malnutrition in the elderly is a serious condition that often gets overlooked (Edfors & Westergren, 2012).
Från Balkan till Sverige : Ungdomars indentitet och historia
The purpose of this essay is to shed some light upon the children who grew up in Sweden after their parents fled the war in former Yugoslavia. Did the parents spread their own opinions about the other ethnicities which they fought against in the war to the children, even though they live in a new country? And if so, was it an act of patriotism for the country they once lived in and who was to blame for the war? Did the children who grew up in Sweden share the same attitudes as their parents? To find out about this we used interviews with four people, all with heritage from former Yugoslavia, Bosnia and Croatia. What we found out was that the thoughts from the parents partially were passed down to their children, even though the children thought that they had formed their own opinions. In this case the thoughts didn?t relate to any kind of patriotism or who to blame for the war, they rather believed that they shouldn?t blame the other ethnic groups for the war.
Applikationsintegrering - en analys av metoder och teknik
Abstract
In the contemporary world of information technology you find a multitude of
applications and systems covering a broad spectrum of areas of need in
different companies. One effect of this multitude of programs is the difficulty
to make them exchange information with each other or to collaborate, since they
are developed by different programming languages for different platforms, with
different standards and different data formats.
Our aim with this work is to describe how it is possible to tie these programs
together to make them actually communicate with each other in order to exchange
information, share their native methods and also to become a part of the
overall business processes. In this integration task you will, among other
things, find different levels of application integration such as data level,
method level, application interface level and user interface level integration.
Application integration also involves hardware components, called middleware,
that facilitate the physical connection between applications. There is a range
of different middleware products offered today on the market.
Tio smutsiga fingrar : en observationsstudie om följsamheten till hygienrutiner på en infektionsavdelning som vårdar patienter med ESBL
Resistenta bakterier är ett växande problem inom den svenska sjukvården. Extended spectrum ß-lactamases (ESBL) är bakterier som kan bilda enzymer som bryter ned antibiotika så att den på så sätt blir resistent. En av de stora anledningarna till spridning av resistenta bakterier är personalens brist på korrekt utförande av basala hygienrutiner. Syftet med studien var att undersöka hur sjukvårdspersonal på en infektionsavdelning tillämpar de riktlinjer för basala hygienrutiner som finns fastställda för personal inom hälso- och sjukvården. Data samlades in genom observationer på en infektionsavdelning på ett sjukhus i Mellansverige.
Mot en grönare organisation : Niscayah i en säker framtid
This paper covers how a company must act to become ?greener? and yet still increase profitability with the main emphasis on the inner structure of the company. The research is focused on the Swedish security systems company Niscayah AB, part of the multinational corporation Niscayah Group with approximately 6000 employees. A company can be assumed to consist of seven parts (strategy, systems, structure, super-ordinate goals, staff, skills and style) that have to cooperate for the firm to be able to become more environmentally friendly. Also, the economic performance is of importance and therefore that too is examined.
