Utomhuspedagogik : En studie om lärares uppfattningar av utomhuspedagogik

In previous contact with secondary schools, we have noticed a dull setting for friluftsliv among teachers in Physical Education and Health. We suspected that both teaching and assessment are sometimes conducted in error. Under the provisions of Skolverket the teacher must involve all elements mentioned in the core content of the curriculum and the assessment of students' knowledge may be based only on what is expressed in the syllabus for each course. Research shows that the implementation of the curriculum have failed in the subjects investigated (Skolinspektionen, 2013:22). We have identified a gap of knowledge regarding the situation of friluftsliv in the course physical education 1.

Upplevd trafiksäkerhet med mittbarriär

AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

Sjukgymnastik i skolan - behövs det?: en kvalitativ studie

The aim of this study was to investigate physical education teachers (PET) view of the needs of physiotherapy in compulsory school. Semi structured interviews were conducted with five PET.

Utvärdering av individuellt märkt text

With the development of the Internet, illegal copying of electronic documents has become a growing problem. There is an increasing need of prevention in the field of pirate copying. One method is to mark the document by changing some of the words to synonyms. In this way it is possible to construct legal copies which do not differ in content but still are unique. Since the copies of the documents are unique, it is possible to trace the owner of a document and accordingly call him or her to account for pirate copying if several exactly similar copies are reaching the market.

Transportoptimering i dagbrott: En fallstudie vid Boliden i Aitik

Gruvbrytning i dagbrott kräver ofta stora kapitalinvesteringar och för att hålla verksamheten lönsam krävs ofta storskalig drift. Truckar utgör ca 60 % av de totala produktionskostnaderna och det är därför viktigt att de används på ett effektivt så att maximal mängd malm kan produceras. Produktionen i en gruva är dynamisk till följd av att tillgängliga vägar, maskinkapaciteter, tillgängliga bergmassor och bergets egenskaper ofta varierar. Dynamiken och de många variablerna gör det svårt att planera och styra produktionen eftersom vissaplaner, såsom exempelvis fördelning av truckar, ofta måste justeras när förutsättningarna ändras.Syftet med den här studien är att kartlägga materialflödet och produktionsstyrningen i ett dagbrott, samt att identifiera förbättringsförslag.En fallstudie har genomförts vid Boliden Mineral AB (Boliden) i Aitik, Sveriges största dagbrott. Bolidens prioriteringar är att (1) maximera totalt producerad mängd malm, (2) möta de dagliga produktionsmål för malm och gråberg som finns för varje enskilt sprängområde, och (3) minimera produktionskostnaderna.

Dagvattendammars reningseffekt : påverkande faktorer och metodik för statistisk modellering

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

Flotation av tellur- och vismutmineral

Vid Boliden Minerals anrikningsverk, i Boliden, planeras ett tellurlakningsverk där det är tänkt att lakningen skall ske i två steg. Varm cyanidlakning görs på flotationskoncentratet och flotationsavfallet skickas för kall cyanidlakning. Varm cyanidlakning görs satsvis och tanken har en maximal gräns för mängden ingående material som styrs av viktsutbyte sulfid hos det ingående material. Ur lakresten från den varma cyanidlakningen planeras för att utvinna tellur genom ytterligare lakningssteg. Även här är det önskvärt att hålla viktsutbytet så lågt som möjligt för att minimera anläggningens storlek.

Markvattenhalt och temperatur i sandig jordbruksmark vid Ilstorp, centrala Skåne : en mätnings- och modelleringsstudie

Vinderosion på jordbruksmark har länge varit ett välkänt faktum trots att någon utförligare undersökning om dess omfattning och skadeverkan inte tidigare genomförts. Mot bakgrund av detta har därför ett nordeuropeiskt projekt, WEELS (Wind Erosion on European Light Soils), dragits i gång som syftar till kartlägga vinderosionen på sandig jordbruksmark i norra Europa och som man i slutändan hoppas ska kunna resultera i en vinderosionsmodell. Detta har genomförts med SOIL modellen, en matematiskt fysikaliskt baserad modell för simulering av vatten och värmeflöde i en skiktad jordmånsprofil..
