Alternativa förpackningsmaterial och konstruktioner för »Hackman tools«-serien

Choosing a new plastic material for a container includes several different steps. In this case,the Finnish company Hackman needed a new type of packaging material for theircutlery- and kitchentool series »Hackman tools«. The project was carried out in cooperationwith the design agency Ytterborn & Fuentes, which has Hackman as a client.Several different demands were put on the material in order to fulfill as many of the clientswishes as possible. The most urgent problem with the existing container was the difficultysfor the customer to clearly see the contents in the container. Because of this problemthe customer tried to open the container in the shop. To avoid this from happening,Hackman wanted a more transparent plastic material that still fulfilled all other necessaryproperties such as strength, viscosity, printability, sealability and exhaustion strength.The final result and recommendation of a polypropylen-plastic (Evacast) was based ondetailed studies of packaging plastics and their properties as well as discussions with plasticconvertersand suppliers. The recommended plastic is avaliable in several different modelsthat fulfill all demands on material properties, environmental aspects, cost aspects and transparency.Apart from the material problem the project also included drafting some sketches and ideason new construction solutions for the container. The construction of the exsisting containerwas also a problem because of its complexity. As a result of the change of material it has beenpossible to simplify the construction.

Facade integration of polymeric solar collectors

The present paper examines building integrated solar collectors with absorbers of polymeric materials. Efficiency measurements of façade-integrated collectors with non-selective black and spectrally selective coloured absorbers are carried out. The performance of the polymeric absorber was compared with solar glass and polycarbonate twin-wall sheets as collector cover. Simulations demonstrate a high solar fraction for a solar combisystem with façade collectors for a well-insulated house in a Nordic climate. Two examples of house concepts with façade collectors are presented which address a new type of customer than the solar enthusiasts with special interest in renewable energy

Development of a Compact Solar Combisystem

Within the frame of the project REBUS, "Competitive solar heating systems for residential buildings", which is financed by Nordic Energy Research, a new type of compact solar combisystem with high degree of prefabrication was developed. A hydraulic and control concept was designed with the goal to get highest system efficiency for use with either a condensing natural gas boiler or a pellet boiler. Especially when using the potential of high peak power of modern condensing natural gas boilers, a new operation strategy of a natural gas boiler/solar combisystem can increase the energy savings of a small solar combisystem by about 80% compared to conventional operation strategies.

Fyrtiotalisterna och äldreomsorgen : massmediala konstruktioner av en ny sorts omsorgstagare

Baby boomers and elderly care: expectations in print media about a new kind of care users The Swedish baby boomer generation – known as the forties generation – has been characterized as youthful and powerful. At present, members of this generation are entering the category of old age and in about ten years they will start reaching ages where the likelihood of encountering elderly care increases significantly. The present study reports on how this expected meeting has been discussed in Swedish newspapers. Data consisted of 481 articles during the period 1995–2012 and was analyzed through qualitative content analysis. Results show that the generation was predicted to become a new type of demanding and self-conscious care users. Claims were backed by descriptions of formative events and typical characteristics that were projected onto a future as care user. Such projections tended to portray care users of present time as passive and submissive, and partly responsible for problems associated with elderly care
