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
How will higher education and research evolve in the future to produce the high-level knowledge and skilled human capital which underpin sustainable societies?This book explores challenges for the post-knowledge society and economy where major socio-economic change is occurring in tandem with advances in digital technologies. It brings together international authors to discuss scenarios against a
This research studied the preferences reported by women and men about their Ideal Body Image for the Opposite Sex (IBIOS), and its association with body mass index (BMI). It also analysed the preferences of each sex for a woman's ideal body image (W-IBI) and a man's ideal body image (M-IBI). A total of 450 participants aged 18-70 years with different weights were studied. Their IBIOS was assessed
AIM: The aim of this study was to determine the value of medical history and physical examination, tumour marker testing, and CT-scanning in the follow-up of patients treated for peritoneal carcinomatosis of colorectal origin.METHODS: Between November 1995 and June 2003, 107 patients were treated by cytoreduction and hyperthermic intra-peritoneal chemotherapy. The treatment was considered effectiv
Purpose of Review: Recent advances in the small field of the rare mixed phenotype acute leukemias (MPAL) are presented focusing on a better understanding of their pathophysiology and search for better therapeutic approaches. Recent Findings: Three aspects of respective classification, therapy, and immunophenotype of MPAL are reviewed. New proposals have been made to segregate MPAL subtypes based o
Critical infrastructures must be both robust and resilient in order to ensure the functioning of society. A key activity in ensuring their proper function is finding and addressing system weaknesses by the means of risk and vulnerability analysis. A critical factor of such analysis is the ability to determine the negative consequences of various types of contingencies. Numerous mathematical and si
Arsenic contamination of drinking water is a result of natural and/or anthropogenic activities, causing undesirable detrimental effects on the environment and the human health. Herein, an integrated process based on Membrane Distillation (MD), photocatalysis and Polymer-enhanced Ultrafiltration (PEUF) was developed for an effective remediation of arsenic (As). This approach, whose effectiveness wa
