BACKGROUND: X-ray micro-tomography (μCT) is a powerful non-destructive 3D imaging method applied in many scientific fields. In combination with propagation-based phase-contrast, the method is suitable for samples with low absorption contrast. Phase contrast tomography has become available in the lab with the ongoing development of micro-focused tube sources, but it requires sensitive and high-reso
Tissue clearing is commonly used for whole-brain imaging but seldom used for brain slices. Here, we present a simple protocol to slice, immunostain, and clear sections of adult rat brains for subsequent high-resolution confocal imaging. The protocol does not require toxic reagents or specialized equipment. We also provide instructions for culturing of rat brain slices free floating on permeable cu
Seaweeds (macroalgae) are gaining attention as potential sustainable feedstock for the production of fuels and chemicals. This comparative study focuses on the characterization of the microbial production of alcohols from fermentable carbohydrates in the hydrolysate of the macroalgae Laminaria digitata as raw material. The potential of a hydrolysate as a carbon source for the production of selecte
Structured triacylglycerols (STAG) with desired properties can be synthesized by transesterification using immobilized lipases. Herein, the effect of immobilization conditions and support material on the immobilization yield, specific activity and regioselectivity of lipases from Rhizomucor miehei (RML) and Rhizopus oryzae (ROL) in the production of STAG, are evaluated. Four different support mate
This paper is concerned with the estimation of macroscopic properties such as the permittivity or the thermal conductivity of a composite material from the microstructure. A new method of estimating the microstructural parameters, such as the volume fraction of anisotropic two-phase composite material, is derived. The parameters are estimated using information from measurements of the random mater
For more than a century the research on the Antikythera Mechanism engaged scientists from a widerange of scientific disciplines searching for clues, in order to solve the mystery that this unique ar-chaeological find poses. The results so far have been spectacular enough to re-write the History ofTechnology providing new aspects on the degree of technological sophistication and scientific de-velop
För att kunna optimera idrottares säkerhet är det viktigt att tränare och medicinsk personal har utbildning i HLR och OB-ABCDE-principerna. För paraidrottare är det också viktigt att ha en plan för hur man tar bort utrustning vid ett trauma. Dessutom rekommenderas det att medicinsk personal alltid är närvarande vid tävlingar, och om möjligt även under idrottarnas träningspass.In order to optimize the safety of athletes, it is important that coaches and medical personnel have training in CPR and the OB-ABCDE principles. For para athletes, it is also important to have a plan for how to remove equipment in the event of a trauma. In addition, it is recommended that medical personnel are always present at competitions, and if possible also during the athletes' training sess
Research is needed to understand attitudes toward and adoption of the broad range of technologies available to support active and healthy aging in different generations. The present article gives an overview of the GenerationTech survey and sample, and describes attitudes and acceptance related to technology in general and as a means to support active and healthy aging. A national survey was condu
A strategy for the formation of thin reconstituted cellulose films (pure or modified)) with embedded receptors or embedded ion-selective components is reported. Cellulose nanofibril ribbons from sisal of typically 3-5 nm diameter and 250 nm length are reconstituted into thin films of typically 1.5-2.0 μm thickness (or into thicker free-standing films). Cellulose and cellulose nanocomposite films a
Using a model disordered mesoporous solid with a spatial arrangement of pore sizes analogous to a macroscopic 'ink-bottle', it has been shown that the hysteresis observed in NMR cryoporometry can be deconvoluted into separate single pore and pore-blocking contributions. The suggestion of pore-blocking effects has been confirmed using PFG NMR. Hence, percolation theory has been used, for the first
Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To assess the effects of caffeine compared to aminophylline or theophylline in preterm infants at risk of apnea, with apnea, or in the peri-extubation phase.
Treatment of chronic osteomyelitis by radical debridement and filling of the dead space with antibiotic containing calcium sulphate/hydroxyapatite (CaS/HA) bone substitute has shown excellent long-term outcomes. However, in extensive infections, sessile bacteria may remain in bone cells or soft tissues protected by biofilm leading to recurrences. The primary aim of this study was to evaluate if sy
Fast-moving consumer goods (FMCGs) are products that have a short useful lifetime and are typically designed for single or limited uses followed by disposal. The disposable nature of FMCGs combined with ineffective waste recovery systems is causing global environmental problems. Various reusable packaging business models have emerged to tackle these problems; however, their influence is still low
Sixteen landcover classes in a representative Swedish environment were analyzed and classified using one Landsat TM scene and seven ERS-1 SAR.PRI images acquired during 1993. Spectral and backscattering signature separabilities are analyzed using the Jeffries-Matusita distance measure to determine which combinations of channels/images contained the most information. Maximum likelihood, sequential
We introduce the combination of digital holographic microscopy (DHM) and antibody microarrays as a powerful tool to measure morphological changes in specifically antibody-captured cells. The aim of the study was to develop DHM for analysis of cell death of etoposide-treated suspension cells. Results/methodology: We demonstrate that the cell number, mean area, thickness and volume were noninvasivel
