Purpose: In a prospective study, we assessed if a diagnosis of osteoporosis and periodontitis could predict hip and hand fractures in older persons. Materials and methods: Bone density was assessed by a Densitometer. Periodontitis was defined by evidence of alveolar bone loss. Results: 788 Caucasians (52.4% women, overall mean age: 76 years, S.D. +/- 9.0, range: 62 to 96) were enrolled and 7.4% ha
Renal function is often estimated using one of several glomerular filtration rate (GFR) estimating equations. However, there is no consensus which estimating equation performs best in patients with advanced renal failure. We compared the performance of five different estimated GFR (eGFR) equations [Cockcroft-Gault, Modification of Diet in Renal Disease (MDRD), Chronic Kidney Disease (CKD) Epidemio
The formation of various aluminides and intermetallic compounds in the Al-Ni-Ti ternary system offers great potential for a wide variety of applications. In the present work, reactions occurring during the heating of compacted ternary Al-Ni-Ti elemental powder mixtures were studied using differential scanning calorimetry (DSC). The effect of composition on the reaction behavior was studied by vary
The building sector contributes to one-fifth of Sweden’s total greenhouse gas emissions (GHG) and consumes 40 % of the final energy consumption. To achieve the climate goals set by the Swedish government, the building sector requires rapid development to reduce its climate impact. The climate impact of buildings comes from two types of energy throughout the building's lifecycle: operational an
This work is an investigation into practical design and loss minimization of DC/DC-switched power supplies, enabling cooler operation, smaller size, and additional or wider areas of use. There is an abundance of switch controller ICs on the market and a few of the manufacturers offer very sophisticated design tools that suggest operating parameters and grade components. However, one of the major
This Master's thesis has concerned the segmentation and classification of background textures in images. In order to segment the images we have used the SLIC algorithm to create superpixels. These are a sort of over segmentation of the image where pixels close to each other and similar in colour are considered to be the same texture. All superpixels were then classified using a convolutional n
När någon går bort försvinner inte det den avlidne efterlämnar sig automatiskt. Ett dödsbo bildas som omfattar den avlidnes tillgångar och skulder. Normalt sett kommer dödsboet att förvaltas av dödsbodelägarna, det vill säga de som på något sätt kommer ha del av det som ingår i dödsboet genom arv eller genom testamente. Det ska eventuellt göras en bodelning mellan efterlevande make och dödsboet. DWhen a person passes away, an estate takes form which includes all the deceased’s assets and liabilities. Normally the estate is being taken care of by the parties to the estate. The parties to the estate is everyone who has a rightful claim on the estate, either by heritage according to Swedish law or according to a will from the deceased. Sometimes a division of the joint property between the sp
Antalet företagsförvärv har vuxit snabbt i Sverige under de två senaste årtiondena och är idag en del av viktiga strategiska och ekonomiska beslut för många företag. Ett företagsförvärv kan dessutom vara en mycket stor ekonomisk risk för den förvärvande parten. Denna uppsats undersöker processen för ett företagsförvärv från den förvärvande partens perspektiv samt ur ett rättsekonomiskt perspektiv.The amount of acquisitions has grown rapidly in Sweden during the past two decades and are today a very important strategic and financial decision for many companies. A corporate acquisition could also be a very big financial risk for the acquiring party. This thesis researches the process of corporate acquisitions from the perspective of the acquiring party with a focus on an economic analysis of
Nibe Industries has grown from being a local Swedish company to a global group with subsidiaries around the world. Nibe has protected its roots and still retains the head office in Markaryd, where they invest heavily in production locally (Nibe Industrier AB, 2020). The master thesis was conducted at the subsidiary Nibe AB in Markaryd within Climate Solutions” business area with a special focus on
Equitable distribution of healthcare services towards the reduction of HIV-AIDS prevalence in Nigeria remains a major public health concern. One of several research model to solve this public health problem is the use Geographical Information System, a two-step floating catchment area (2SFCA), this model emerged in the last decade as a key measure of spatial accessibility, particularly in its appl
The aim with this master thesis was to investigate if a certain sow feed requires different calibrations in near-infrared analysis, due to if the sow feed have fish oil or AkoFeed as fat source. To investigate this, a basic sow feed mix was prepared and divided in 60 jars with 250 g in each. In 30 of the jars 0 to 15 g fish oil were added and in the other 30 jars 0 to 21 g AkoFeed were added. 2/
Background: Perioperative myocardial injury (PMI) is associated with increased short-term major adverse cardio- and cerebrovascular events (MACCE) and mortality. We evaluated how different phenotypes of PMI based on timing of injury impact long-term MACCE and mortality among patients undergoing major noncardiac surgery (NCS). Methods: A prospective, observational study was carried out in 1290 pati
Background: The Swedish National Board of Health and Welfare centralized the surgical care of patients with anorectal malformations from four to two centres in 2018. This retrospective review compares short-term complications after anorectal reconstruction before and after centralization. Methods: Hospital records of all infants in Sweden who underwent reconstruction of an anorectal malformation b
As climate models can be used to reproduce historical climates, the outcomes can be used to put climate extremes in to a proper historical perspective. This also allows investigation of nonlinear properties of hydrologic processes (e.g. precipitation, runoff) to better understand regional hydrologic dynamics. To this end, the present study uses results from a so-called 'paleosimulation' (i.e. simu
Objective: To characterize the trend of opioid use (number of users, dispensations and oral morphine milligram equivalents) in Catalonia (Spain). Design, setting, and participants: This population-based cohort study included all individuals aged 18 years or older, registered in the Information System for Research in Primary Care (SIDIAP), which covers >75% of the population in Catalonia, Spain, fr
Background: Despite the advancement of electrocardiogram (ECG) monitoring methods, the most important factor influencing diagnostic yield (DY) may still be monitoring duration. Ambulatory ECG monitoring, typically with 24–48 hours duration, is widely used but may result in underdiagnosis of rare arrhythmias. Aims: This study aimed to examine the relationship between the DY and monitoring duration
Circular economy (CE) is still a nascent research field in the built environment, however, has gained traction in the last decade. Despite it being generally accepted that sustainability consists of three dimensions, namely, social, environmental, and economic, CE has been criticised for focusing on environmental and economic impact whilst neglecting the social aspect. Further, CE has been critici
