Treatment and nursing of birds with wing fractures
Vingfrakturer Àr en vanlig orsak till att fÄglar behöver vÄrd pÄ veterinÀrkliniker. Syftet med arbetet
var att söka vetenskaplig information om behandling och omvÄrdnad av vingfrakturer hos fÄglar.
Intentionen var Àven att jÀmföra skillnaderna pÄ behandling och omvÄrdnad mellan tamfÄglar och
vilda fÄglar. Vidare fokuserar arbetet pÄ att utforska om fÄglar med vingfrakturer kan lÀka och ÄterfÄ
sin förmÄga att flyga igen efter behandling. Arbetet bestod av en litteraturstudie och personliga
intervjuer. Till litteraturstudien anvÀndes bÄde vetenskapliga artiklar och lÀroböcker för att hitta
information. För intervjuerna kontaktades tre veterinÀrer och tvÄ djursjukskötare som arbetade pÄ
veterinÀrkliniker som var specialiserade pÄ exotiska sÀllskapsdjur. Av de fem personer som
kontaktades kom tre till intervju.
I litteraturgranskningen framkom det att röntgendiagnostik anvÀnds för att avgöra om det finns en
fraktur och utröna vingfrakturens utseende. Bandagering Àr den vanligaste behandlingsmetoden som
anvÀnds för att pÄbörja lÀkningsprocessen. Detta arbete ger information om hur behandling och
omvÄrdnad för fÄgel med vingfraktur kan utformas. I arbetet jÀmförs de skillnader som fanns att
hitta i den sökta litteraturen inom behandling och omvÄrdnad mellan tamfÄglar och vilda fÄglar.
Resultatet i arbetet tyder pÄ att fÄglar Àr svÄra patienter att hantera och behandla, dÄ de lÀtt blir
stressade och döljer smÀrta. Det finns trots det en chans att fÄglarna kan ÄterhÀmta sig frÄn en
vingfraktur om personalen pÄ kliniken har rÀtta kunskaper. Det spelar Àven in om djurÀgaren avsÀtter
tid och arbete för att optimera fÄgelns vÀlmÄende under lÀkningsprocessen.Wing fractures are a common reason why birds need care at veterinary clinics. The aim of this
bachelor thesis was to obtain scientific information regarding the treatment and care of wing
fractures in birds. The intention was also to compare the differences in treatment and care between
domestic birds and wild birds. This bachelor thesis focuses on exploring if birds with wing fractures
can heal and regain their ability to fly again after treatment. The bachelor thesis consisted of a
literature study and personal interviews. For the literature study, both scientific articles and
textbooks were used to find information. For the interviews, three veterinarians and two veterinarian
nurses who worked at veterinary clinics specializing in exotic pets were contacted. Three of those
five were booked for interview.
In the literature it was found that x-ray diagnostics are used to determine if there is a fracture and
confirm the appearance of the wing fracture. Bandaging is the most common treatment method used
to begin the healing process. This bachelor thesis provides information on how the treatment and
nursing of a wing fracture can be designed. The work compares the differences that were found in
the applied literature in the treatment and nursing between domestic birds and wild birds.
The results of this bachelor thesis indicate that birds are difficult patients to manage and treat, as
they easily become stressed and conceal pain. There is nevertheless a chance that the birds can
recover from a wing fracture if the staff at the clinic has the right knowledge. It also matters if the
animal owner allocates time and work to optimize the bird's well-being during the healing process.

Ăr resursfördelningen rĂ€ttvis? Skillnader inom och mellan kommuner - en rĂ€ttvisefrĂ„ga.
Since the municipalization of primary school in the early 1990s, has a fair education within and between muncipalities been discussed. The purpose of this case study is to examine Frasers (2011) equitable theory of economic redistribution, cultural recognition and political representation against the effects on fairness of municipalization. The aim is to see if the municipalities are responsible to freely allocate resources to primary schools, create equity between schools within and between municipalities, by answering questions about how resource allocation affects a fair education, the municipalitiesâ freedom to allocate resources based on local conditions, as well as if concerning local resource allocation to primary school is fair from Fraserâs perspective. The study is based on state public inquiries, reports and investigations of, for example, Swedish Governments Official Reports (SOU), Swedish Association of Local Authorities and Regions (SKL), National Agency for Education (Skolverket) and the Swedish Schools Inspectorate (Skolinspektionen) but also literature relating to equitable primary education. The analysis of the material based on Fraserâs theory shows that the municipalitiesâ freedom to allocate resources to primary schools do not create a fair education. Economic redistribution, cultural recognition and political representation are three dimensions which together, create an equal participation in social life
Genusperspektiv pĂ„ nationalekonomi â vĂ€lkommet eller motarbetat?
Ekonomiska fakulteten vid Lunds universitet beslutade Är 2013 att genusperspektiv ska ha en framtrÀdande roll i undervisningen. Genom intervjuer med undervisande personal pÄ Nationalekonomiska institutionen undersöker denna studie vilka möjligheter de anstÀllda har att följa de direktiv som Ekonomiska fakulteten beslutar om. Studien analyserar universitetslÀrarnas svar utifrÄn teorin om förstÄ, kan och vill, vilka Àr de tre egenskaper som Lundquist anser behövs för att beslut ska verkstÀllas. Graden av uppfyllelse av Lundquists kriterier för god implementering varierar kraftigt mellan de intervjuade och det finns varierande möjligheter för de intervjuade att uppfylla policyn. Undersökningen Àr gjord utifrÄn ett traditionellt perspektiv pÄ styrning, och arbetar med ett top-down-perspektiv vilket under arbetets gÄng fÄtt utvecklas dÄ modellen för styrningen kan diskuteras
Strategier personer med multipel skleros anvÀnder sig av i sin vardag
Syftet med studien var att undersöka vilka strategier personer med multiple skleros anvÀnder sig av för att handskas med sjukdomen dÄ den innebÀr skiftande dagsform. Sju personer deltog i studien, tvÄ mÀn och fem kvinnor. Studien hade en kvalitativ ansats och datainsamlingen skedde genom intervju med hjÀlp av en egengjord intervjuguide. Efter innehÄllsanalys identifierades tre kategorier och ett flertal subkategorier. Resultatet visade att alla deltagare anvÀnde sig av olika strategier i sin vardag,. Att informera sina anhöriga om sjukdomen fungerade som en social beredskap för individerna att ta till vid behov av stöd. Andra strategier var olika typer av energibesparing genom anvÀndande av hjÀlpmedel, att planera sin vardag sÄ att energin rÀckte till, samt att lyssna pÄ sin kropp och inte köra över sig sjÀlv. En positiv och aktiv livsstil visade sig Àven vara av stor vikt. Trots att sjukdomen pÄverkade mycket sÄ upplevde alla individerna sig ha livskvalitet och en innehÄllsrik vardag, och de betonade vikten av att fokusera pÄ det positiva, det man tycker Àr kul, det man kan och det man vill
Characterization of Natural Killer Cell Phenotype and Function during Recurrent Human HSV-2 Infection
Human natural killer (NK) cell differentiation, characterized by a loss of NKG2A in parallel with the acquisition of NKG2C, KIRs, and CD57 is stimulated by a number of virus infections, including infection with human cytomegalovirus (CMV), hantavirus, chikungunya virus, and HIV-1. Here, we addressed if HSV-2 infection in a similar way drives NK cell differentiation towards an NKG2A-NKG2C+KIR+CD57+ phenotype. In contrast to infection with CMV, hantavirus, chikungunya virus, and HIV-1, recurrent HSV-2 infection did not yield an accumulation of highly differentiated NK cells in human peripheral blood. This outcome indicates that human HSV-2 infection has no significant imprinting effect on the human NK cell repertoire
Novel Method for Controlled Wetting of Materials in the Environmental Scanning Electron Microscope
Environmental scanning electron microscopy has been extensively used for studying the wetting properties of different materials. For some types of investigation, however, the traditional ways of conducting in situ dynamic wetting experiments do not offer sufficient control over the wetting process. Here, we present a novel method for controlled wetting of materials in the environmental scanning electron microscope (ESEM). It offers improved control of the point of interaction between the water and the specimen and renders it more accessible for imaging. It also enables the study of water transport through a material by direct imaging. The method is based on the use of a piezo-driven nanomanipulator to bring a specimen in contact with a water reservoir in the ESEM chamber. The water reservoir is established by local condensation on a Peltier-cooled surface. A fixture was designed to make the experimental setup compatible with the standard Peltier cooling stage of the microscope. The developed technique was successfully applied to individual cellulose fibers, and the absorption and transport of water by individual cellulose fibers were imaged
A self-consistent hybrid Comptonization model for broad-band spectra of accreting supermassive black holes
The nature of the broad-band spectra of supermassive accreting black holes in
active galactic nuclei (AGNs) is still unknown. The hard X-ray spectra of
Seyferts as well as of Galactic stellar-mass black holes (GBHs) are well
represented by thermal Comptonization, but the origin of the seed photons is
less certain. The MeV tails observed in GBHs provide evidence in favour of
non-thermal electron tails and it is possible that such electrons are also
present in the X-ray emitting regions of AGNs. Using simulations with the
kinetic code that self-consistently models electron and photon distributions,
we find that the power-law-like X-ray spectra in AGNs can be explained in terms
of the synchrotron self-Compton radiation of hybrid thermal/non-thermal
electrons, similarly to the hard/low state of GBHs. Under a very broad range of
parameters the model predicts a rather narrow distribution of photon spectral
slopes consistent with that observed from LINERs and Seyferts at luminosities
less than 3 per cent of the Eddington luminosity. The entire infrared to X-ray
spectrum of these objects can be described in terms of our model, suggesting a
tight correlation between the two energy bands. We show that the recently found
correlation between slope and the Eddington ratio at higher luminosities can be
described by the increasing fraction of disc photons in the emitting region,
which may be associated with the decreasing inner radius of the optically thick
accretion disc. The increasing flux of soft photons is also responsible for the
transformation of the electron distribution from nearly thermal to almost
completely non-thermal. The softer X-ray spectra observed in narrow-line
Seyfert galaxies may correspond to non-thermal Comptonization of the disc
photons, predicting that no cutoff should be observed up to MeV energies in
these sources, similarly to the soft-state GBHs.Comment: MNRAS publishe
Investigations on path indexing for graph databases
Graph databases have become an increasingly popular choice for the management of the massive network data sets arising in many contemporary applications. We investigate the effectiveness of path indexing for accelerating query processing in graph database systems, using as an exemplar the widely used open-source Neo4j graph database. We present a novel path index design which supports efficient ordered access to paths in a graph dataset. Our index is fully persistent and designed for external memory storage and retrieval. We also describe a compression scheme that exploits the limited differences between consecutive keys in the index, as well as a workload-driven approach to indexing. We demonstrate empirically the speed-ups achieved by our implementation, showing that the path index yields query run-times from 2x up to 8000x faster than Neo4j. Empirical evaluation also shows that our scheme leads to smaller indexes than using general-purpose LZ4 compression. The complete stand-alone implementation of our index, as well as supporting tooling such as a bulk-loader, are provided as open source for further research and development
Radiation Induced Point and Cluster-Related Defects with Strong Impact to Damage Properties of Silicon Detectors
This work focuses on the investigation of radiation induced defects
responsible for the degradation of silicon detectors. Comparative studies of
the defects induced by irradiation with 60Co- rays, 6 and 15 MeV electrons, 23
GeV protons and 1 MeV equivalent reactor neutrons revealed the existence of
point defects and cluster related centers having a strong impact on damage
properties of Si diodes. The detailed relation between the microscopic reasons
as based on defect analysis and their macroscopic consequences for detector
performance are presented. In particular, it is shown that the changes in the
Si device properties after exposure to high levels of 60Co- doses can be
completely understood by the formation of two point defects, both depending
strongly on the Oxygen concentration in the silicon bulk. Specific for hadron
irradiation are the annealing effects which decrease resp. increase the
originally observed damage effects as seen by the changes of the depletion
voltage. A group of three cluster related defects, revealed as deep hole traps,
proved to be responsible specifically for the reverse annealing. Their
formation is not affected by the Oxygen content or Si growth procedure
suggesting that they are complexes of multi-vacancies located inside extended
disordered regions.Comment: 14 pages, 15 figure
