We report on the shear-induced transition from an oriented lamellar phase (L, phase) to multilamellar vesicles (MLV) in two nonionic surfactant systems, namely, a 40 wt % sample of triethylene glycol monodecyl ether (C10E3) and a 40 wt % sample of tetraethylene glycol monododecyl ether (C12E4) in D2O. This transition was studied by time-resolved small-angle neutron and light scattering under shear

Neuroinflammation is a major contributor to the progressive brain injury process induced by traumatic brain injury (TBI), and may play an important role in the pathophysiology of axonal injury. The immediate neuroinflammatory cascade cannot be characterized in the human setting. Therefore, we used the midline fluid percussion injury model of diffuse TBI in rats and a novel microdialysis (MD) metho

The increased demand for high purity nanoparticles (NPs) of defined geometry necessitates the continuous development of generation routes. One of the most promising physical techniques for producing metal, semiconductor or alloy NPs in the gas phase is spark discharge NP generation. The technique has a great potential for up-scaling without altering the particles. Despite the simplicity of the set

Avian migrants may fly at a range of altitudes, but usually concentrate near strata where a combination of flight conditions is favourable. The aerial environment can have a large impact on the performance of the migrant and is usually highly dynamic, making it beneficial for a bird to regularly check the flight conditions at alternative altitudes. We recorded the migrations between northern Europ

This paper investigates the quantification of FPGA resources for the implementation of closed-loop combustion control algorithms. Specifically, the study focuses on methods for their in-cycle execution and control of the combustion in real-time. A National Instruments Xilinx Virtex-5 platform was used for the quantification of the resources.Closed-loop combustion control obtains feedback from fast

Reproduction is a critical part of an animal's life history, but one which incurs significant costs to survival and future reproductive potential. These physiological consequences are likely to be influenced by context – for example, if an individual is subject to environmental stressors, physiological and behavioral changes associated with reproduction may be altered. Glucocorticoids, hormones pr

In the course of my PhD work, I have been involved in the development and the construction of the Tagging System for the BGO-OD experiment at the ELSA accelerators of the University of Bonn.BGO-OD is a fixed target experiment for the investigation of the structure of the nucleon at low energies via the photoproduction of mesons. It consist of a central calorimeter and a forward spectrometer. The r

Our model deals with a single-product and a single-stock location with Poisson demand. The replenishment leadtime from the external supplier is fixed. The lifetime of the product is also fixed, and aging is assumed to begin when the order is placed. When the age of a unit has reached its lifetime, the unit is useless and thus discarded from the system. The replenishment policy is assumed to be an

The present study aimed to investigate how the impact of several factors linked to geography would shape life-history traits in a gregarious species, using the pine processionary moth (PPM) Thaumetopoea pityocampa as a model system. PPM has a wide geographical distribution over the Mediterranean Basin, and it is a strictly gregarious species throughout larval development, where the total reproduct

Popular Abstract in Swedish Den viktigaste uppgiften inom den kliniska cytologin är att påvisa cancerceller i olika typer av cellprover. Många olika cancertumörer sprider sig till lungsäcken och bukhålan och ger då ofta upphov till vätska (exsudat) som innehåller cancerceller. Ofta kan cancerdiagnosen ställas på grundval av cellernas utseende men detta är inte alltid möjligt, eftersom cancercellerClinical cytology is a rapid method to detect malignancy in effusions of the serous cavities, but the morphological characteristics of the cells do not always allow diagnosis and a specific marker for malignant cells would improve the diagnostic performance. Telomerase adds telomere repeats to the chromosome ends. It is the most promising universal indicator of malignancy and the project focuses o

A Holocene lake sediment record is presented from Lake N14 situated on Angissoq island 15 km off the main coast of southern Greenland. The palaeoclimatic development has been interpreted on the basis of flux and percentage content of biogenic silica, clastic material, organic material and sulphur as well as sedimentation rate, moss content and magnetic susceptibility. A total of 43 radiocarbon dat

Background: Patients with possible radiation induced cancer could be used to study if the rate of tumour cell proliferation is related to latency time. Such a finding could help researcher to find time periods when other initiating risk factors operate. Methods: Seventeen women with breast cancer, with a prior history of radiation treatment towards the parts or the whole breast, exclusive of the p

Bell’s palsy is an acute onset of peripheral facial nerve dysfunction. Despite extensive research the aetiology is unclear. The most prevailing theory is that reactivation of viruses such as Herpes simplex type-1 or Varicella zoster may cause Bell’s palsy. The natural course is favourable but at least 30% of patients will suffer sequelae such as residual paresis, synkinesis and/or contracture. The

Although Cloud Sourcing has been around for some time it could be questioned what actually is known about it. This paper presents a literature review on the specific question if Cloud Sourcing could be seen as the next generation of outsourcing. The reason for doing this is that from an initial sourcing study we found that the sourcing decisions seems to go in the direction of outsourcing as a ser

The latest Cyrtograptus lundgreni graptolite Chron (Late Wenlock, middle Silurian) is characterized globally by the Mulde Event faunal extinctions and glacio-eustatic sea-level change. Only in the last decade has it been recognized as one of the most severe extinction events of the Silurian Period. A section spanning the Slite Group-Halla Formation boundary on the islet Ytterholmen off main Gotlan

The accomplishments of the Nordic Myeloma Study Group (NMSG) during its first 15 yr are briefly surveyed, together with a discussion of principles guiding the group's clinical trials and of problems that need to be addressed in coming years. The group has so far carried out 12 clinical trials, comprising more than 2500 patients, spanning from minor phase II to large randomised phase III trials. At

Design has received increased attention not least of all in the business press and journals. The concept of design thinking – how to approach problems in a designerly way – is sometimes attributed as being the savior of business, making companies creative and innovative. This kind of exaggeration does more harm than good to industrial design consultancies (IDCs) and their client firms (CFs). And y

Although fever (a closely regulated increase in body temperature in response to infection) typically is beneficial, it is energetically costly and may induce detrimentally high body temperatures. This can increase the susceptibility to energetic bottlenecks and risks of overheating in some organisms. Accordingly, it could be particularly interesting to study fever in small birds, which have compar

That a load balancing strategy using stale information care lessly will incur system performance degradation is easy to verify. However it is not so obvious that routing a customer to the expected shortest queue has the same problem when information for decision is stale. We consider a queueing system with a load balancer and a pool of identical FCFS queues in parallel. The arrival process is assu
