Näringsretention i återskapad våtmark på betesmark : studier av en mad vid Bornsjön

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

Gestaltningsfloran : en brygga mellan hortikultur och biotopgestaltning

Contemporary plant design can be examined by how it relates to two Extremes - Nature and Art. This idea is explained by Noel Kingsbury in the book The Dynamic Landscape where he places designers and their projects on a gradient (Kingsbury, 2004). Nature, one of the Extremes can be represented by a dynamic, species-rich plant design with native species and with nature as the ideal. The other Extreme - Art implies a more static view on plant design. Here, the designs consist of colourful flowers, exotic species and cultivars with double flowers.

Enabling behaviour change : community-based social marketing strategy in Malmö

Our planet is faced with enormous challenges as the Extreme weather events related to the human-caused climate change continue to gain strength. The scale of the problem has made changing human behaviour the central focus of sustainable development, and both public and private sector are expected to gain relevant expertise and introduce this work in their agenda. Over its 40-year history, social marketing has become an established field providing tools for social change, but compared to health promotion, sustainability has not been a major focus of social marketing research so far. At the same time, sustainable lifestyles are embedded in complex systems where both individual factors and those of physical and social environment play a defining role in their adoption. Communities are a good example of such environments, and they became the key focus of Community-Based Social Marketing, which combines different insights from psychology to suggest a step-by-step framework for crafting behaviour change campaigns. However, it has not been applied to larger and diverse communities, like cities, and has not focused on sustaining new behaviour over time, which is crucial for creating sustainable lifestyles.

Ett (o)tillåtet undantag eller en (ny)etablerad regel? : - En studie av den nuvarande folkrättsliga regleringen av humanitär intervention

AbstractThis essay has as its purpose to discuss the current legal regulation of the concept of humanitarian intervention. The inconsistencies in the debate over the legal status of this concept, and the legal uncertainty it brings to the acts of states and the lives of their nationals is a motivating factor for the writing of this essay. However, it has been clear from the outset that the concept of humanitarian intervention is intricately connected to political and moral ideas and values. Thus, the attitude taken towards this doctrine will be highly dependent on the perspectives of the state, government or single author representing it.Following this starting point, the aim of this essay is not to present a single answer as to whether humanitarian intervention is, or is not, legal, but to research, compare and analyze the different arguments put forward in this subject in international law today. Hopefully, this will provide the reader of this essay with some insight into the sources of international law of today and how the principles of state sovereignty, non-intervention, the prohibition of force and the protection of human rights relate to the concept of humanitarian intervention.A frank overview of the UN Charter does not support use of force except in the case of self-defence or without a Security Council mandate.

Hur påverkar en ökad andel solceller Umeå Energis elnät? : ? En utredning med fokus på spänningsvariationer och osymmetri inom landsbygds- och tätortsnät vid en- och trefasanslutning av solcellsanläggningar

A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.

Collaborating for Corporate Social Responsibility : the case of conflict minerals in global supply chains

Corporate Social Responsibility (CSR) refers to adjusting corporate goals so that they are not only based on maximizing corporate profits, but include ethical standards on socially desirable behavior (Boatright, 2008). Even though many companies have integrated CSR into their business operations, there are still many issues that are difficult to tackle. Especially Multinational Corporations (MNCs) in the global business environment face many challenging situations due to the fact that they often have linkages to countries where the local government is either unwilling or unable to take care of its responsibilities. MNCs often find themselves with increased responsibilities when they start solving some of the issues that earlier have been the sole responsibility of states. A specific case situation discussed in this paper is related to ?conflict minerals?.

Textil fotokatalytisk vattenreningsreaktor: Optimering av beredningsparametrar för titandioxidbeläggning på polyestersubstrat ämnad för vattenrening

I denna kandidatuppsats avlägsnas organiska föroreningar från vatten genom användning av textilier, vars yta belagts med nanopartiklar utav ämnet titandioxid. När titandioxid belyses med UV-strålning sker en fotokatalytisk reaktion, vilket i sin tur bryter ned bland annat bakterier och organiska färgämnen. I hopp om att finna ultimat vidhäftning mot textil passande titandioxid har olika typer av beläggningar studerats; akrylbaserade, sol-gel och slutligen en hybrid. Dessutom har fem olika konstruktioner av textila bindningar jämförts i syfte att undersöka dess påverkan på den fotokatalytiska effekten. Förorenade vatten är ett stort problem, både i utvecklingsländer och i industriella sammanhang.

Felkällor och systematiska avvikelser i kvalitetsuppföljningen av tidnings- och journalpapper

I papperstillverkning ställs det krav inte bara på kvalité och kvantitet utan också att stickprov från produktion utförs och tas hand om på ett korrekt sätt. Från det att ett stickprov tas ut och undersöks på brukets laboratorium kan en del källor till förändringar på provresultatet uppstå. Sådana förändringar kan uppstå för det första vid hanteringen av stickprov från pappersmaskin och provens transportering till laboratoriet och för det andra vid laboratoriets hantering och uppföljning av kvalitén. En annan faktor som kan påverka stickproven är klimatet. Årstiderna vår och höst är de tider som proverna kan påverkas mest.

Konkurrenssituationen för den skånska grönsaksproduktionen :

The vegetable production in Sweden is concentrated to the very southern parts of the country. This is also were the major wholesalers are located. In recent years, there has been an Extreme focus on price on the food market. As there are only a few big wholesalers and also very few food retail chains, these have a great impact on the producers. The pressure from prominent vegetable-producing countries, providing low price products, such as the Netherlands and Spain is strong.

Design, anläggningsmetoder och skötseltekniker för hagmarksbestånd :

SUMMARY Establish a pasture There is many valuable nature and culture landscapes in Sweden that has developed during a long period of time, throw natural processes or human use. Unfortunately lot of these are disappearing. My thought with this work is to explore the possibility to establish new areas with similar qualities. The motive for this is that attractive countryside biotopes are well worth to use as model to enrich the urban landscape. Another thought has concerned the people that establish, build and manage landscapes and parks. They often have varied views, both coming from a difference in background and previous experiences.
