Hur miljövänlig är dagens optikerbutik, och hur miljövänlig kan den bli?
SUMMARYEnvironmental issues are currently a hot topic of debate. Studies within the optics branch have not specifically been conducted previously, so the aim of this study was to determine the extent of environmental-awareness specifically within this branch.A survey, consisting of questions relating to environmental issues, was distributed to 100 randomly-selected opticians in Sweden. Of these 100 surveys, 64 were returned and showed a varied branch-engagement for environmental issues.Results of this survey showed that opticians were best in sorting newspapers, magazines, other paper and hazardous waste. Metal and rigid plastic were not sorted to any larger extent.Choosing environmentally-safe products was not so popular and only six stores always do this. 25 shops turn off electrical machines and equipment over night; while the majority of the remaining stores leave the machines on during the night.27 stores did not know if their electrical company provided ?green electricity?.Results showed that there is a lot of work to be done in making the stores more environmentally friendly.
?ÄNTLIGEN!?- En lysrörsarmatur för det egna hemmet
The aim of our study is to ascertain whether a hanging suspension fluorescentlamp for a private home environment is going to be attractive for a largeaudience. We want to open up for new uses of fluorescent lamps as lightsources.The main approach in this work is how to design a fixture with fluorescentlamps as a light source that will meet the requirements and requests of thehome environment could look like. At the same time we want to make a newimpression of how a fluorescent light source.Primarily we used a quantitative method, but this was rejected after a pilotstudy. Instead we used a qualitatively based method in the sense that weconducted a group interview as well as individual interviews.Based on data from the interviews and our preliminary work a prototype wasbuilt. This prototype is a fluorescent fixture equipped with 2x14W T5fluorescent lamps, dimmed separately.
Modeller för utvärdering av set-up för återvinning av lastlister inom IKEA
Reverse logistics is getting more and more attention both from companies and the public. It is an area with the possibility for companies to do good in the eyes of the public. This work focus on the return system of a one-way handling material called the loading ledge. The loading ledge is developed by IKEA as a substitute for the EUR-pallet in transports from suppliers with a long distance and even flow and in transports from suppliers with short distance and uneven flow. The loading ledge is made out of 100 % recyclable plastic.The purpose of this work is to find the most efficient set-up for recycling of loading ledges within IKEA on a European level from a transport and handling point of view considering aspects like cost, environment, time and, from an administrative point of view, user-friendliness.Who will the participants of the set-up be, where will they be located, which transports are needed and which income and costs does the set-up generate, are questions that will be answered.
Emballage för väggelement i trä : Paketering, hantering, lager och transport
As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.
Utvärdering av BD Vacutainer® Rapid Serum Tube vid analys av S-Paracetamol och S-Etanol
Avdelningen för klinisk kemi vid Länssjukhuset i Kalmar analyserar läkemedel och alkoholer med BD Vacutainer® Plus Plastic Serum Tube (Serum Tube), som kräver en koagulationstid i upp till 60 minuter. BD Vacutainer® Rapid Serum Tube (RST?) innehåller trombin och kräver en koagulationstid på endast 5 minuter. Syftet med studien var att undersöka möjligheten att förkorta den preanalytiska väntetiden före centrifugering vid intoxikationsanalyser i serumrör från akutmottagningen. Studien utfördes genom att jämföra RST? med Serum Tube vid analys av S-Paracetamol och S-Etanol.
Perspektiv på fostran : En begreppsanalytisk studie av fostran i Lgr-11
Syftet med denna uppsats är att göra en begreppsanalys av begreppet fostran för att undersöka vad begreppet innebär, hur begreppet används i den senaste svenska läroplanen, samt undersöka vem som tillskrivs ansvaret för elevens fostran då begreppet förekommer i grundskolans läroplan utan vägledning för tolkningen av begreppet.Begreppsanalysen gjordes i två delar. Den första delen gjordes genom att studera och sammanställa fostrans betydelse i ordböcker, -listor och lexikon, samt hur begreppet används för att belysa vem som tillskrivs ansvaret för elevens fostran. Resultatet av begreppsanalysens första del visar att det är en innehållsmässig, och inte bara grammatisk, skillnad mellan begreppen fostra och fostran, där fostra handlar om att överföra kunskaper medan fostran mer handlar om att påverka beteende.Begreppsanalysens andra del gjordes genom att studera hur begreppet fostran används i läroplanen. Resultatet visar att det i läroplanen talas om två olika sorters fostransarbeten. Det första handlar om specifika värden som skolan ska förmedla och gestalta och det andra fostransarbetet är det elevens föräldrar som har ansvar för, det innefattar bl.a.
Minkvalpars beteende i större berikade burar vid olika gruppstorlek :
Farmed mink often perform stereotypic behaviours which is considered to be a sign of reduced welfare. Previous studies have shown that enriched cages can reduce the frequency of performed stereotypies. Most studies on mink in Sweden have been done on adults. The aim of this study was to investigate if larger enriched cages with two or four mink kits reduce stereotypies in mink kits during their growth period in comparison to traditional cages.
In the present study the behaviours of mink kits that were kept in four different treatments at a private mink farm were recorded. Traditional cages with two mink kits were used as a reference and the other treatments consisted of larger cages with shelves with two kits, larger cages with shelves and a plastic cylinder with two kits, and larger cages with shelves with four kits.
From paper to plastic ? En studie om tidningens egenskaper och la?sarnas anva?ndningsmo?nster
E-papperet är ett medie som i framtiden kan komma att användas för att läsa dagstidningar. Istället för att bläck trycks på papperet så visar e-papperet informationen genom att små partiklar på papperets yta byter färg vilket innebär att samma e- pappersark kan innehålla och visa ett stort antal sidor. Nya medier blir sällan accepterade utan att det funnits länkar till tidigare eller existerade tekniker. Denna studie ämnar kartlägga tidningsläsarnas användningsmönster och papperstidningens egenskaper för att understödja utformningen av morgondagens e-papperstidning. Genom att kombinera litteratur med egna undersökningar presenteras riktlinjer för vilka egenskaper och användningsmönster som framtidens e-papper bör stödja.
Just In Time : Effektivisering av materialflöden med hjälp av principer från Inventory Management och Production Management
AbstractManagement is a field that started getting attention in the beginning of the 20th century by Frederick Taylor. His publication is called the Principles of Scientific Management and is based on the principles of using scientific methods to find the best way of conducting each operation within a production facility. Many of Taylor?s principles may appear obsolete today but the matter of an effective material flow is still highly current. Efficiency is the relationship between the input into an operation and its result.
Standardisering av förpackningar på HABO AB
This thesis project has been written and accomplished in cooperation with HABO AB. The objective of the project was to develop a standard stated packaging system. The background to this is that HABO is not pleased with the system currently in use. The system which HABO is currently using consists of to many sizes. The largest benefit of a standard stated system is that it becomes much easier to organize the packaging with the aid of a computer program.
Mulesingens historia och framtid, samt desskonsekvenser för djurvälfärden.
Mulesing is a surgical husbandry procedure performed on lambs in Australia. The reason is toprevent severe fly-strike to the breech area, which otherwise risks to be soiled with faeces.This problem is mainly occurring in sheep of the Merino breed. Their fine wool is in demandworldwide due to high quality. Mulesing has been performed since the 1930?s, and eventhough alternative methods have been discussed nothing is yet generally accepted.
Energikartläggning hos RostiGP i Gislaved
In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a power quality clamp meter to carry out time logs of the machines for some time during normal word rate.
Transportfo?rpackningar och marknadsfo?ring av frukt och gro?nt inom dagligvaruhandeln : en pilotstudie i Sverige och Tyskland
The logistic business Svenska Retursystem AB was founded by the Swedish retail sector in
the year 2000, and their introduction of a grey plastic crate to the supply chain for perishable
goods changed the situation for the swedish horticultural sector. The new system revealed
several challenges to be tackled by all actors, from the small family firm to the bigger
organisations. Whereas the initiative comes from the customer himself, from the horticultural
sector ?s point of view, a refusal of the new packing is a hard decision to take. It is however
interesting that a comparison between the two systems, shows in favour of the corrugated
board boxes, not only concerning environmental aspects but also for economical and
ergonomical reasons.
Köldbryggors inverkan på isoleringsegenskaper för sandwichelement : Anslutning mellan fönster och yttervägg
I dagens läge har energifrågorna väckt ett stort intresse i samhället. Nu fokuseras det mer på att bygga energisnålare hus. En betydande faktor som påverkar energiförbrukningen i våra hus är köldbryggor. De uppstår då ett material med dålig värmeisolering bryter igenom ett material med bättre värmeisolering. Köldbryggor är nästan omöjligt att undvika, dock går alltid att reducera.
Evaluation of Ectopar for the control of the poultry red mite Dermanyssus gallinae
The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great
discomfort for the hens and effecting the production economically. Few efficient acaricides are available
and there is a need for new control methods since resistance has become a problem in some cases.
The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).
