Metal cutting is a very common operation in the manufacturing industry. Drilling and other hole-making operations perhaps account for 50% of all metal cutting, according to some investigations. All metal cutting including drilling always produces burrs, as a by-product. Actually burrs are nothing but uncut metal at the beginning and at the end of the operations. Yet, despite burr's omnipresence in
Background. Dosimetry of the hypothalamus-pituitary (HP) region could allow prediction of the risk of growth hormone deficiency (GHD) following cranial irradiation. Procedure. Nineteen children (15 boys) with a median age of 6.3 years (range 1.7–16.5) at the time of irradiation of a brain tumor not involving the HP axis were followed for 1.2–6.3 years (median 3.4) from radiotherapy (RT). The dose
Diabetic foot ulcer is an important entity which in many cases is the first serious complication in diabetes. Although a plantar forefoot location is common, there are few studies on larger cohorts and in such studies there is often a combination of various types of ulcer and ulcer locations. The purpose of this study is to discern the outcome of plantar forefoot ulcers and their specific characte
Avian blood parasites have been preliminarily studied in East Asia, but no data are available from long-term monitoring. The aim of this study was to evaluate the prevalence, genetic diversity, and temporal dynamics of Plasmodium, Haemoproteus, and Leucocytozoon in two passerine communities (one forest and one urban) in north China from 2008 to 2013, as well as the association between infected lin
We have developed a new approach to create microsatellite primer sets that have high utility across a wide range of species. The success of this method was demonstrated using birds. We selected 35 avian EST microsatellite loci that had a high degree of sequence homology between the zebra finch Taeniopygia guttata and the chicken Gallus gallus and designed primer sets in which the primer bind sites
Minimal residual disease (MRD) detection during the early treatment phase has become an important stratification parameter in many childhood acute lymphoblastic leukaemia (ALL) treatment protocols. Here, we aimed to address the applicability of rearranged antigen-receptor genes as potential MRD markers using real-time quantitative polymerase chain reaction (RQ-PCR) in a Swedish population-based co
Background. The overall purpose of the present study was to attain more insight in month-to-month variation of sleep duration and quality in order to improve design and interpretation of, e.g. epidemiological studies using sleep as outcome. Methods. The study design entailed monthly self-reports from 38 (26 women/12 men) daytime workers, who completed the Karolinska Sleep Diary (KSD) once a month
This study was performed to elucidate circulatory changes in the fetal cerebral circulation during uncomplicated labor and in early neonatal life. Eighteen healthy term singleton fetuses were followed longitudinally during labor. Using the transabdominal approach, and the color Doppler technique, the middle cerebral artery was identified and Doppler flow velocity waveforms recorded between and dur
Background and Purpose - The causes of death of patients with cerebral venous thrombosis (CVT) have not been systematically addressed in previous studies. We aimed to analyze the causes and predictors of death during the acute phase of CVT in the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT) to identify preventable or treatable causes. Methods - ISCVT is a multinational,

Controls were 57 age-matched boys assigned to the general school curriculum of 60min/ week. Bone mineral content BMC; g) and areal bone mineral density (aBMD; g/cm(2)) were measured with dual X-ray abso
PURPOSE: To describe complications and visual outcome of photocoagulation for clinically significant macular oedema. SUBJECTS AND METHODS: Evaluation of macular oedema and complications of photocoagulation in 194 eyes, defined as subretinal fibrosis, atrophic creep of the pigment epithelium and subretinal neovascularization was based on stereo fundus photo grading. The study included 25 patients w
Context: We have previously found that visceral fat is a stronger predictor for cardiovascular risk factors than body mass index (BMI). Objective: This study sought to investigate the prevalence of diabetes in elderly men and women in relation to objectively assessed visceral fat volume. Design and Setting: The cohort consisted of a population-based sample of 705 men and 688 women, all age 70 y at
Dealing with water diffuse pollution is a major problem for watershed managers. This problem raises many complicated questions, which are important to answer in order to reach water environment protection goals. This study suggested some possible answers for the country of Lithuania. Among them were the identification of critical source areas, the identification of sensitive areas and the applicat
Vid avdelningen för kärnfysik utvecklas för närvarande andra generationens Ir-koincidensspektrometer. Anledningen till detta är att det finns ett stort behov bland geologer att mäta spårkvantiteter av Iridium i olika geologiska skikt för att korrelera skiktens ålder med eventuella stora meteoritnedslag. Första generationens spektrometer byggde på en dubbelkoincidens mätt med två HPGe-detektorer, mPresently, the development of the second generation Ir coincidence spectrometer is talking place at the division of Nuclear Physics. There is a large need among geologists to measure trace quantities of Ir in different geological layers and correlate the age of the layer with different large meteorite impacts. The first generation Ir spectrometer was based on a coincidence measured by two HPGe det
I nuläget har vi levt med covid-19-pandemin och dess medföljande restriktioner, rekommendationer och budskap i över ett år. De konstant återupprepade budskapen kring ämnet har resulterat i att människor tröttnat på att följa restriktioner och uppmärksamma informationen, vilket WHO beskriver som pandemic fatigue.

Lasten i ett fjärrvärmenät varierar mycket över dygnet på grund av variationer i väder, utomhustemperatur och användning av tappvarmvatten. För att driften av produktionsenheter ska bli jämnare används ofta värmeackumulering, de flesta fjärrvärmenät har tillgång till en ackumulatortank som kan fyllas med varmt vatten när lasten är låg för att sedan pumpa ut det i nätet vid hög last. I det här proj
Det får anses vedertaget att barn är en särskilt utsatt grupp världen över. Gifta barn, som dessutom är asylsökande, är alldeles särskilt sårbara. Insikten om detta bör genomsyra all lagstiftning som avser barn, där barnets bästa ska sättas i främsta rummet. Uppsatsens övergripande syfte har varit att undersöka ett i utlandet gift barns rätt att i Sverige återförenas med sina föräldrar. Syftet haIt may be considered accepted that children are a particularly vulnerable group worldwide. Married children, who are also asylum seekers, are particularly vulnerable. The realization of this should permeate all legislation concerning children, where the best interests of the child shall be a primary consideration. The overall purpose of the essay has been to investigate a child married abroad righ
In this thesis a system for tracking the fingers of a user using sound waves is developed. The proposed solution is to attach a small speaker to each finger and then have a number of microphones placed ad hoc around a computer monitor listening to the speakers. The system should then be able to track the positions of the fingers so that the coordinates can be mapped to the computer monitor and be
