Removal efficiency of perfluoroalkyl substances (PFASs) in drinking water : evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon
Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. Furthermore, PFASs have also been detected in drinking water, leading to raised concerns for human health, since drinking water is one of the most significant sources of PFASs for the general population. Conventional water treatment techniques have shown to be ineffective removing PFASs, highlighting the importance for further research to develop efficient removal techniques.
The aim of this study was to investigate the removal efficiency of PFASs in water using two treatment techniques; granular activated carbon (GAC), type Filtrasorb 400®, and anion exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied.
Om att lära sig prestera under press
I have researched different methods for practicing with the purpose of learning some useful ways to handle my performance anxiety issues, to better understand the phenomenon, and to be able to perform better under pressure. I chose or created nine methods and used each during a decided period of time, each period ending with a performance. Afterwards I analyzed the methods with the help of audio recordings and written concert evaluations to see if it was possible to alter my practicing techniques to be more directly focused on preparing for the concert situation..
Siffror istället för bokstäver : Övergången från SAB till DDK i Sigtuna kommuns folkbibliotek
The purpose of this thesis is to examine the transition from SAB to DDC in the public libraries of Sigtuna.More specifically, it aims at investigating why the decision was made to adopt the DDC and how the system has been implemented. Particular attention is drawn to the difficulties and problems that have arisen while organising the libraries open shelves with DDC and to the ways in which the difficulties have been handled. These questions are examined through a pragmatic perspective on Knowledge Organization that focuses on the contexts and domains in which the classification system is used. The empirical material is drawn from qualitative interviews with the former director of Sigtuna public libraries and with the in-charge of the catalogue department. .
Drama & vägledning : Metoder som speglar livet
This study illustrates how drama methods and career counselling might interact. The aim is to investigate whether drama methods can enhance career counselling methods. Drama is here defined as an umbrella term that includes all forms of action methods used in psychology and education.A literature survey was carried out in parallel with qualitative research interviews. Three professional drama leaders were interviewed separately. This was followed by a group interview with five upper secondary school students, who had all taken a course in drama with a focus on personal development.The findings show that there are common and consistent goals and values between drama and career counselling.
Perceptuell identifiering av musikgenre
This is a study in the field of Music Information Retrieval (MIR) concerning classification of musicgenre. The study uses a music listening experiment and machine learning methods to determinewhether or not the drum sounds from different songs contain sufficient information to classifygenre.MIR methods are used to extract data from the audio signals. The data is used together with theclassification results of the listening experiment to train different machine learning algorithms toclassify the songs in different genres.The results indicate that using only drum sounds for genre classifications works well, both forlisteners and for machine learning methods..

En studie om möjligheter att stoppa förfalskningar : Spårbarheten i en global värld
The purpose of this study is to describe the traceability of products that protect against counterfeiting and examine how protection against counterfeit products have been developed to date, and to display the opportunity to streamline the protection of products and brands.Nowadays, in the global world, it is getting increasingly more difficult to track the products. Especially for the last link in the chain, which in most cases is the customer and who is constantly exposed to risks. This report deals with the possibilities of preventing and detecting counterfeit products. Fake products are not unusual in an historical perspective. It has been common with counterfeits ever since the Middle Ages continuously until today. Forgers have become more skillful and they are successful in most industries. Many of the fake products are of poor quality and can be downright dangerous to the customer.To answer the question, the author used a qualitative collection method.

Aim Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) is an international survey tool based on parents' estimation of their child's motor coordination skills. The purpose of this study was to investigate the validity of a Swedish version of DCDQ'07 by finding out how the classification of Developmental Coordination Disorder (DCD) via DCDQ'07 is consistent with the classification of DCD via the motor impairment test, Movement ABC.MethodIn the context of a larger study, a Swedish translated version of the parent survey DCDQ'07 were sent to 4000 randomly selected families with children aged 8 - 10 years in Stockholm County. The classifications "DCD" or "NOT DCD" with cut-off values ??of 56 (9 years) and 57 (10 years) were applied. Forty families were selected from 410 registered responses.
Automatisk genreklassifikation : en experimentell studie
This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.

Trafikklasser för markplattor av natursten : förslag till klassificeringstabell
This report deals with hard surfaces and the factors which are behind the criteria for dimensioning, also dependent on the level, or volume, of traffic. A test was made on slabs of two kinds of natural stone. This was made to see if the values that were reached for breakload was transferable to the same tables that the concrete industry is using for surface dimensions of slabs and paving stones. The test showed very high values and the result, together with the written study, led to the author?s suggestion for a classification table where slabs of natural stone were divided in to different classes depending on traffic, thickness and durability..

Evenemang : Great event of Karlstad & Mariebergsskogen
In my study I have chosen to examine the mathematics in children's free play and everyday situations, with focus on sorting and classification. The purpose of the study was to see how children express their mathematical knowledge. I have chosen to use a qualitative method in my examination, here I did observations in a children's group where the children were between three and six years old. I also did interviews with the teacher's on the department to see how they relate to the mathematics and how they formulate the department to achieve as good a learning environment as possible.The result shows that the teacher's approach is incredible important to the children's learning ability and that they are always present to challenge and discuss together with the children. The observation indicates that children use mathematics all the time in their everyday situations and that it is the interaction between individuals and environment that affects children's development. .
