Radio-controlled model planes are useful when carrying out photography, especially from low altitudes, and meteorological soundings (air temperatures in boundary layers). Soundings were carried out with a system which stored the measured data on board the plane pending evaluation after the flight. The payload of the plane was a camera and equipment for measuring temperature and air pressure (altit
The present work reports on testicular hormone-sensitive lipase (HSL), the biological significance of which has been documented in male fertility. The HSL protein levels and enzymatic activity were measured, respectively, by densitometry of immunoreactive bands in Western blots, performed with antibodies against recombinant rat HSL, and by spectrophotometry in seminiferous tubules (STf) and inters
The sexes' share in parental care and the social mating system in a marked population of the single-brooded Lesser Spotted Woodpecker Dendrocopos minor were studied in 17 woodpecker territories in southern Sweden during 10 years. The birds showed a very strong mate fidelity between years; the divorce rate was 3.4%. In monogamous pairs, the male provided more parental care than the female. The male
1. Recent reviews demonstrate that genetically determined alternative mating strategies (AMS) are widespread and typically consist of morphs that are recognized by morphological or colour traits. Despite well-established behavioural differences associated with each morph, and evidence that androgens are involved in the induction of morphs, few studies have examined whether morphs also vary in whol
Aim. To 'own' a person is considered an infringement of human rights, but we suggest that concepts of ownership influence interactions between parents and staff when a child is admitted to hospital. This paper aims to stimulate debate and contains an explanation of the exploration of the literature for research and discussion of ownership of the child. Method. A wide variety of library indexes, da
Objective: To compare the accuracy of fetal weight estimation in large fetuses using four ultrasound formulas. Design: Prospective comparative study. Setting: University Hospital, Lund, Sweden. Population: Large-for-gestational age fetuses (n = 114) at a routine ultrasound examination in the third trimester. Methods: Persson & Weldner two-dimensional formula was compared with Hart et a
Tailbiting codes are error correcting codes and can be used in digital transmission systems. They are obtained by terminating convolutional codes into block codes. This thesis consists of an introduction to convolutional and tailbiting codes, and the Papers A--G that include the main results. In Paper A, the error correcting capability of tailbiting codes is described via the active distances for
We present age- and gender-specific normative bone status data evaluated by quantitative ultrasound (QUS) in the calcaneus with the Lunar Achilles device and compare these estimates with bone mineral content (BMC) and bone mineral density (BMD) estimated by dual X-ray absorptiometry (DXA). Included were a sample of 518 population-based collected Swedish girls and 558 boys aged 6-19 years. QUS meas
Background: Computed tomography (CT) of the brain is performed with high local doses due to high demands on low contrast resolution. Advanced algorithms for noise reduction might be able to preserve critical image information when reducing radiation dose.PurposeTo evaluate the effect of advanced noise filtering on image quality in brain CT acquired with reduced radiation dose. Material and Method
The problem of empty names derives from the fact that empty names fail to refer. The reference failure of empty names implies that sentences containing empty names lack truth-conditions. As a consequence those sentences are meaningless, according to many theories of meaning. The present dissertation addresses the problem of empty names and proposes a solution to the problem at hand. In brief, the

Borderline Personality Disorder (BPD) has largely been associated with self-harm and chronic suicidality, despite the fact that these behaviours comprise only one diagnostic criterion. Treatments for self-harm are mostly indicated for individuals with BPD. Emerging literature suggests that youth with histories of depression are at risk of both self-harm and completed suicide. For individuals with
Popular Abstract in Swedish En ny typ av vattenlösliga fosfin ligander har utvecklats. Dessa fosfiner har använts som ligander i rhodium katalyserade tvåfasreaktioner.Komplexbildningen mellan de nya liganderna och olika metalcentra har studerats och de nya komplexen har använts i hydroformylerings- och hydreringsreaktioner. Polymerbundna kirala fosfiner har använts i enantioselektiv hydrering.Four new water-soluble phosphines have been prepared by utilising water-soluble polymers as charge carrying units. Coupling of methyl-4-(diphenylphosphino)-benzyl-amine or 4-diphenylphosphino benzaldehyde to poly-acrylic acid and poly-ethylene imine, respectively, afford the ligands PAA-PNH and PEI-PNH. Coupling of (2S,4S)-4-diphenylphosphino-2-di-phenylphosphino-methylpyrrolidine (PPM) or (R,R)-3
An algorithm specific digital signal processor is a powerful alternative to a general purpose signal processor for demanding specifications such as high throughput, low power, small size, etc. These properties are achieved as the processor architecture is tailored to the algorithm as opposed to the general purpose architecture which must suit a wide range of algorithms. The increased performance i
The main goal of SASPENCE is to develop and evaluate an innovative system able to perform the Safe Speed and Safe Distance concept, that means to help the driver in avoiding accident situations related to excessive speed or too small headway. So, the system should co-operate seamlessly with the driver, suggesting the proper velocity for the given condition (road structure, traffic situation, etc.)
This study investigates the public reading of New Testament writings in early Christian communities during the first two centuries C.E. from the perspective of the lectors who prepared and performed the readings. A survey of literary and pictorial sources from the Greek and Roman world indicates that only oratory and drama were delivered from memory, whereas most literary writings were read aloud
In the discipline of archaeology death has always been a common subject. Graves and dead bodies in different states of decay are important sources of information. This dissertation investigates how our relation to death can be mirrored through some of the better-known individuals from prehistory in Scandinavia. Because of the character of the question at issue I start with three chapters in which
