Hydrodynamic interactions in systems composed of self-propelled particles, such as swimming microorganisms and passive tracers, have a significant impact on the tracer dynamics compared to the equivalent "dry" sample. However, such interactions are often difficult to take into account in simulations due to their computational cost. Here, we perform a systematic investigation of swimmer-tracer inte
During the past 25 years, the combination of increasingly sophisticated gene targeting technology with transplantation techniques has allowed researchers to address a wide array of questions about postnatal mammary gland development. These in turn have significantly contributed to our knowledge of other branched epithelial structures. This review chapter highlights a selection of the mouse models
Spiders have been suspected to be one of the most important groups of natural enemies of insects worldwide. To document the impact of the global spider community as insect predators, we present estimates of the biomass of annually killed insect prey. Our estimates assessed with two different methods suggest that the annual prey kill of the global spider community is in the range of 400-800 million
Nations around the world are feverishly developing new standards relating to Building Information Modelling (BIM) in the construction industry which may enable teams to leverage greater value from BIM implementation and model authorship efforts. This study reflects on ongoing standardisation initiatives in Sweden and considers where current research efforts fit in. There is limited research presen
Background and purpose There are no reports in the literature on the influence of learning on the pedicle screw insertion. We studied the effect of learning on the rate of screw misplacement in patients with adolescent idiopathic scoliosis treated with segmental pedicle screw fixation. Method We retrospectively evaluated low-dose spine computed tomography of 116 consecutive patients (aged 16 (12-2
In this thesis, liquid-membrane-based methods for the analysis of trace metal species in samples of environmental and biological origin were developed. By incorporating extracting reagents in the membrane liquid, trace metal ions were selectively separated from humic-rich natural waters and urine samples, prior to their determination using various instrumental techniques. The extractions were perf
The fire technical properties of products are determining factors for the initiation and growth of fires. Measurement of fire technical properties and the understanding of how they relate to real hazards are therefore important for fire safety. This work deals with the fire technical properties of building products, their tendency to ignite and release heat in different fire scenarios. Building p
The bacterial flora of the gastro intestinal (GI) tract may be involved in chronic inflammation and colon cancer and affected by antibiotics, cytotoxic drugs and radiotherapy, trauma and intensive care therapy. It is important to map the mucosa-associated flora in healthy individuals to clarify the pathogenic risk under stressed conditions. The aim was to achieve an overview of the mucosa-associat
Popular Abstract in Swedish Melatonin är ett hormon som produceras i, och frisätts från pinealorganet hos ryggradsdjur. Melatoninets viktigaste uppgift är att till hjärnan förmedla signalen om nattens längd, d.v.s vilken årstid det är. Produktionen och frisläppningen sker rytmiskt med den högsta nivån under natten. Melatoninet transporteras ut i kroppen via blodet och binder till särskilda mottagaMelatonin is a neurohormone which mediates photoperiodic signals from the pineal organ to the brain. GABA (g-aminobutyric acid) is the major inhibitory transmitter in the central nervous system. It has previously been suggested that functional interaction exists between central binding sites for GABA/benzodiazepines (GABAA/bzd receptors) and melatonin in the central nervous system, and that GABA a
Introduction: Early excision and skin grafting has become the standard of good burn management, but it is associated with major blood loss. Aim: To determine the haemostatic effect of terlipressin compared with placebo. Material and methods: Fifty-one patients with bums of 10-20% total body surface area had early excision and split skin grafting of deep burns. The surface area of the bum wound and
Human papillomavirus (HPV) infection is a necessary cause of cervical cancer and cervical dysplasia. Accurate and sensitive genotyping of multiple oncogenic HPVs is essential for a multitude of both clinical and research uses. We developed a modified general primer (MGP) PCR system with five forward and five reverse consensus primers. The MGP system was compared to the classical HPV general primer
Using the combined Golgi-electron microscopy technique, we have determined the three-dimensional dendritic fields of the short visual fibres (svf 1-3) and first-order interneurons or L-fibres (L1-4) within the first optic ganglion (lamina) of the nocturnal bee Megalopta genalis. Serial cross sections have revealed that the svf type 2 branches into one adjacent neural unit (cartridge) in layer A, t
Objective: To analyse the extent to which traumatic life events, post-traumatic stress disorder (PTSD) and the neuropsychiatric disorder attention deficit hyperactivity disorder (ADHD) can be contributors associated with burnout and the long-term sick leave that results from it. Subjects: Sixty-two individuals on long-term sick leave due to stress-related poor health and burnout, and 83 working in
It has been generally accepted that increasing aerosols suppress precipitation. The aerosol-induced precipitation suppression was suggested by the study of shallow stratiform clouds. Recent studies of convective clouds showed increasing aerosols could increase precipitation. Those studies showed that intense feedbacks between aerosols and cloud dynamics led to increased precipitation in some cases
Dysthymia and major depressive disorder (MDD) are both risk diagnoses for suicidal behaviour. The aim of the present study was to identify clinical differences between these disorders, with a special reference to dysthymia. We studied suicidal behaviour, comorbidity and psychiatric symptoms of inpatient suicide attempters with dysthymia and MDD. We used DSM III-R diagnostics, the Suicide Assessmen
