Onychophorans typically possess a pair of simple eyes, inherited from the last common ancestor of Panarthropoda (Onychophora + Tardigrada + Arthropoda). These visual organs are thought to be homologous to the arthropod median ocelli, whereas the compound eyes most likely evolved in the arthropod lineage. To gain insights into the ancestral function and evolution of the visual system in panarthropo

In LTE base-stations, RoHC is a processingintensive algorithm that may limit the system from serving a large number of users when it is used to compress the VoIP packets of mobile traffic. In this paper, a hardware-software and a full-hardware solution are proposed to accelerate the RoHC compression algorithm in LTE base-stations and enhance the system throughput and capacity. Results for both sol

OBJECTIVES:: The objectives of this clinical trial of orally administered manganese in magnetic resonance imaging (MRI) of the liver were to assess signal enhancements in the liver with and without the addition of an uptake promoter, ascorbic acid, and to evaluate acute safety. MATERIALS AND METHODS:: A total of 18 healthy adult males were enrolled in the present trial. Contrast medium: MnCl2, dos

This Master’s thesis in library and information science deals with the relationship between research and practice of information literacy education. Information literacy is a common field of research and many theories and models have been developed through the years. The concept is widely used in society and one goal for educational institutions is to train students to become information literate.

The purpose of this thesis is to through the analysis of interviews with finance professionals in listed companies answer the question on what lies behind capital structure decisions, and to see how well the prevailing theories fit the answers. This article is an explorative and descriptive hypothesis creating study. We have used a qualitative method to analyse practice through theory. We have con

The intention of this study was to inquiry how the social workers at the social service offices in Helsingborg perceive the homeless and their situation, and what kind of aid and support the homeless are getting so they can change their situation. We have also examined how the homeless describe their own situation and how they experience the treatment and the help they get from the social workers.

The purpose of this composition was to find out, from a child’s point of view, where, what and with whom children play. Our ambitions were also to examine if perspectives like gender, ethnicities and different types of housing will strike off the children’s play. Our main questions regarded the signification of language in choice of playmate, the resemblance and difference in girls respectively bo

Kognitiv beteendeterapi (KBT) kan idag erbjuda evidensbaserade behandlingar för de flesta psykiska sjukdomar, men har inte utvecklats systematiskt för svagbegåvade personer med psykiska besvär. Individerna i denna osynliga befolkningsgrupp är emellertid extra sårbara för psykisk ohälsa pga sina sociala livsvillkor, samt sina psykobiologiska förutsättningar. Med stöd i forskning om KBT för lågbegåCognitive-Behavioural-Therapy (CBT) can today offer evidence-based treatments for most psychological disorders, but has not developed systematically for people with borderline intellectual functioning (IQ 70-85) and their psychological disorders. Individuals in this unseen population are, however, exceptionally vulnerable to psychological disorders because of their social life situation, as well a

This thesis regards datapath design and analysis at several abstraction levels. Five papers are presented that focus on datapath design for mobile communication systems and design methodologies for such datapaths. Paper I discusses different aspects of Turbo channel decoder design for high speed and low power applications. It is shown that critical path delay is significantly reduced by simple re

The inception of the sheet flow regime as well as the effects of the phase lag when the sheet flow regime is established were investigated for oscillatory flows and combined steady and oscillatory flows. A new criterion for the inception of sheet flow is proposed based on around 300 oscillatory flow cases from experiments. This criterion was introduced in the Camenen and Larson [Camenen, B., Larso

Popular Abstract in Swedish De flesta primärar hjärntumörer utgår ifrån astrocyter, oligodendrocyter och ependymala celler, som är hjärnvävnadens egna celler. Cirka hälften av dessa tumörer ingår i en grupp där tumörtypen heter gliom. Glioblastoma multiforme (GBM) är den mest elakartade tumören inom denna grupp och också den vanligast förekommande.Trots stora forskningssatsningar är behandlingsstrGlioblastoma multiforme (GBM) is the most malignant and also the most common form of brain tumour in humans. The overall aim of this thesis was to investigate morphological and diagnostics features in human GBM that may be of importance for prognosis and treatment. Immunohistochemically stained tissue sections have been microscopically analysed regarding immuno-reactive cells, cell proliferation,

Accurate and precise determinations of thermodynamic parameters of binding are important steps toward understanding many biological mechanisms. Here, a multi-method approach to binding analysis is applied and a detailed error analysis is introduced. Using this approach, the binding thermodynamics and kinetics of the reconstitution of the protein monellin have been quantitatively determined in deta

Multi-objective performance assessment of operational strategies at wastewater treatment plants (WWTPs) is a challenging task. The holistic perspective applied to evaluation of modern WWTPs, including not only effluent quality but also resource efficiency and recovery, global environmental impact and operational cost calls for assessment methods including both on- and off-site effects. In this stu

Agricultural production systems are affected by complex interactions between social and ecological factors, which are often hard to integrate in a common analytical framework. We evaluated differences in crop production among farms by integrating components of several related research disciplines in a single socio-ecological analysis. Specifically, we evaluated spring barley (Hordeum vulgare, L.)

This paper presents the design and characterization of millimeter-wave (28/38 GHz), circularly polarized (CP) active antennas, suitable for the future 5G services. By augmenting the modelling capabilities of commercially available nonlinear CAD tools, the active antenna design can simultaneously optimize figures of merits for both radiation and non-linear (NL) performance. The radiating part is co

In this study, we developed a nanoparticle-based mesoporous composite that consisted of silicate-titanate nanotubes (STNTs) supported in hydrogel chitosan beads (STNTs-Ch beads) and was studied for Cd2+ adsorption. By using Fourier-transform infrared spectroscopy, transmission and scanning electron microscopy coupled to an energy-dispersive X-ray spectrometer, we coulddetermine that the hollow STN

Experimentation has become a popular term amongst those interested in fostering more sustainable social futures. But the ways in which researchers and policy makers have thought about experimentation have generally been with reference to new infrastructural and governance conditions. Focusing on intentional interventions downplays the capacity for change stemming from peoples’ already existing pra

We present the first comprehensive, long-run estimates of Finnish wealth and its distribution from 1750 to 1900. Using wealth data from 17,279 probate inventories, we show that Finland was very unequal between 1750 and 1850; the top decile owned about 90% of total wealth. This means that Finland was more unequal than the much wealthier economies Britain, France and the US, which goes against the c

G protein-coupled receptor 30 (GPR30) is a G protein-coupled receptor (GPCR) that is attracting considerable attention in breast cancer and cardiometabolic regulation. Following reports that GPR30 is required for some rapid estrogen responses, e.g. increased cAMP production and ERK1/2 activity, in estrogen receptor (ER)-negative cells, GPR30 was renamed G protein-coupled estrogen receptor 1 (GPER1

For years, it is an actuality in the poultry processing industry, that the body and the cardiovascular system of the chickens are not strong enough due to the shortened rearing time. This induces, that the quality of the chicken breast is not appropriate for selling, since during the processing procedure, frequently blood spots appear inside the meat. These damaged parts need to be removed, causin
