Utvärdering av mikrofon- och högtalarelement för högtalartelefonsapplikation

The project deals with the evaluation and testing of speaker and microphone elements as well as microphone Cavity.The first part of the report comprises a comprehensive theoretical part about drivers, microphone elements, and to some extent microphone Cavity.The goal was to , on the behalf of the company Limes Audio AB, develop proposals on microphone element and Cavity as well as drivers for a speakerphone application, based on specific factors. The main factors were performance, price and form factor.The aim was to create the best possible conditions for Limes Audio's software developers to implement the company's audio-enhancing software, mainly adaptive echo cancellation.The testing was carried out using Adobe Audition and MatLab. The test methods were developed in conjunction with Limes Audio and are described below.The project will result in suggestions for a speaker, a microphone and a Cavity. The Cavity were removed from the product because the results indicated that the Cavity matter little for the end result.The report concludes with a discussion on how the measurements could have been enhanced to simplify the interpretation of the results and making the testing more efficient..

Datering av röta i hålekar :

I have chosen in this work to examine which factors are affecting the artificially creation of a tree Cavity containing decomposed wood. The purpose of the work is to find out which factors are affecting the most when a tree Cavity is created, and to apply these results when you artificially try to create a tree Cavity. The need to create tree cavities comes from the situation where many tree Cavity living beetles finds themselves today. When existing trees are to pass out there will be no suitable inheritors yet. The work was initially to focus on cavities created from cut branches.

Identifiering av lek- och övervintringsområden för lax (Salmo salar) och öring (Salmo trutta) i Klarälven

Old hollow trees of oak contain a large amount of wood mould. Unfortunately, these trees have in the last century been greatly reduced in numbers. It has resulted in that species that depend on these habitats, saproxylic species, have become at risk to decrease in numbers or die out regionally. Previous studies have shown that the volume of wood mould is an important factor for occurrence and population size of saproxylic organisms. The aim of the present study was to examine how the volume of wood mould varies among ash (Fraxinus excelsior), lime (Tilia sp.), maple (Acer platanoides), aspen (Populus tremula) and oak (Quercus robur).

Munvårdinterventioners samt personalutbildningsinterventioners effekter på munhälsan hos äldre patienter

Senior citizens require a healthy oral Cavity and healthy teeth in order to eat, speak and preserve their well-being. With age we know that the incidence and prevalence of diseases and symptoms originating from the oral Cavity are more common compared to younger age groups. Senior citizens are the fastest growing population on earth, thus the need of healthcare providers with knowledge and skills in oral healthcare are in great demand.  The purpose of this thesis is to identify oral healthcare interventions and educational interventions which have been shown to improve oral health of residents over 65 years of age.  A literature review was conducted in which 15 scientific articles were scrutinized. Databases used were PubMed, Cinahl and Scopus. The results imply that good oral healthcare not only improve the oral health of senior citizens, but also prevents the occurrence of other diseases such as pneumonia and  improve the overall quality of life.

Från ståtlig befästning till vittrande världsarv : En jämförelse av byggnadstekniska metoder för sammanbindning av skalmurar

This is a final year project considering constructional techniques for joining Cavity walls. The project is related to an ongoing scientific programme about the restoration of The City wall of Visby located on Gotland. The programme was set by Riksantikvarieämbetet as a reaction to a collapse of the outer masonry wall shell which took place in February 2012.The City wall of Visby is a medieval fortification built out of limestone during the 13th century. The wall is constructed as a Cavity wall with two separate masonry shells connected to each other through an intermediate core. During the 14th century the wall was heightened which lead to a higher stress, especially in the outer wall face.

Seventy-two working horses (they had been ridden with bit and bridle within the last two weeks) were examined in the oral Cavity. Findings and status were noted. The horses were randomly chosen among individuals without clinical symptoms from the mouth and gastrointestinal system. The result showed that 93% of the horses had changes in the mucus membranes, 86% in the form of ulcerations. The P2 region was most commonly affected followed by wounds more caudally in the mouth (P3-M3 region).

Finns det ett samband mellan ökad mjölkproduktion och mastit?

The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

Intuberingsmetoder och alternativa metoder att tillföra inhalationsanestetika för allmän anestesi på kanin

Handling of animals during anaesthesia is an important field in the profession as a veterinary nurse and in which intubation is an essential part. Hence, adequate knowledge is necessary for the welfare of the animal. The objective of this literature study was to make it useful and trustworthy for veterinary nurses. It is intended to describe and summarize existing scientificity with its benefits and disadvantages within the different areas of intubation techniques and alternative methods of inhalation anaesthetic supplementation for general anaesthesia in rabbits. Endotracheal intubation in rabbits can be complicated and technically demanding due to the anatomy of the oropharynx including the narrowness of this structure, a relatively large tongue, large incisors and a limited mobility of the temperomandibular joint. The obstructed visualization of larynx and the rabbit?s tendency to develop laryngospasm contributes to the difficulty of intubation. Rabbits are susceptible to tracheal injury and multiple intubation attempts can cause tracheal lesions due to repeated damage to the tracheal mucous membrane, although damage can occur after a single intubation attempt as well. An ETT (endotracheal tube) with or without a cuff can be used during orotracheal intubation in rabbits.

Metodik för bakteriologisk provtagning från näshålan på får :

Respiratory infections are one of the major causes of disease in sheep throughout the world. In the beginning of 2008 the Swedish National Veterinary Institute and the Swedish Animal Health Service together started a project about respiratory infections in Swedish sheep. This study is an initial part of that project and the aim of this study was to investigate different sampling possibilities with focus on nasal swabs. This study is composed partly of a literature review on causative agents of respiratory infections in sheep and existing sampling methods, and partly of an experimental study comprising 56 sheep. These sheep were sampled with both an ordinary nasal swab and a guarded nasal swab. Before the start of this study there was to our knowledge no described method for sampling sheep with a guarded swab.

Kunskap om och upplevelse av halitosis samt klinisk mätning av svavelhaltiga gaser bland gymnasieelever

The aim of this study is to examine the knowledge and experience of the bad breath among high school students in Kristianstad. A further objective was to measure the amount of VSC (Volatile Sulfur Compounds) among those who perceive themselves to have a bad breath. A questionnaire with 21 closed questions was distributed to 120 high school students from Kristianstad municipality who were between the ages of 17-20. The results of this study revealed that most of the students had good knowledge of halitosis. The majority of all participants thought it was important to smell fresh in the mouth and also experienced most of their breath as very good or good.
