Several methods are used to evaluate knee articulation during movement, such as the Tibio Femoral Contact Point migration or the Instantaneous Centre of Rotation displacement and even the Moment Arm variations during extension. Such evaluation is important in case of Anterior Cruciate Ligament reconstruction or Total Knee Replacement, but unfortunately, it is only available in research settings...

The availability and usage of portable image intensifiers has revolutionised routine orthopaedic practice. Extensive use of fluoroscopy however may result into significant radiation exposure to operating staff. An accumulated dose of 65 microSv per procedure over long exposure has been reported to increase the risk of thyroid cancer. The present prospective study aimed at measuring the scattere...

Sentence adverbials build a multidimensional constituent in many languages, i.e. they can, among others, modify the meaning of entire sentence, emphasize particular element it, or coherence texts. Due to multifaced character this linguistic phenomenon acquisition it foreign language learners can be complex process. The learner is not only faced with variety different words and phrases that used...

Based on the findings of mixed-methods research conducted with 279 Muslim prisoners in 10 prisons England, Switzerland and France, this paper argues that contemporary European are sites intense religious change, which many people born outside Islam born-Muslims believe practise for first time. In order to map experience change prison, articulates an original typology conversion identify convert...

Over the last twenty years, significant progress has been made in the technical development of night vision equipment. There are a number of different approaches. Image intensifiers amplify ambient light so that it can be presented via phosphor displays including those embedded within night vision goggles. This technology relies upon light from the stars or moon, as well as from man-made source...

Performance characteristics of various readout systems coupled to an EGG-AVO streak camera were analyzed and compared to scaling estimates. The purpose of the work was to determine the limits of the streak camera performance and the optimal fielding conditions for the Amador Valley Operations(AV0) streak camera systems. We measured streak camera limitations in spatial resolution and sensitivity...

We describe a state-of-the-art tunable ultraviolet (UV) Raman spectrometer for the 193-270 nm spectral region. This instrument allows for steady-state and transient UV Raman measurements. We utilize a 5 kHz Ti-sapphire continuously tunable laser (approximately 20 ns pulse width) between 193 nm and 240 nm for steady-state measurements. For transient Raman measurements we utilize one Coherent Inf...

Sentiment analysis assumes the task of identifying positive, negative, and neutral thoughts as well as emotional and subjective attitudes of the holder to the target audience, such as products, persons, or topics. Sentiment analysis is emerging as a research field attracting the scientific community. This includes the construction of emotional lexicons as a basis for other sentiment analysis pr...

A high-speed camera that combines a customized rotating mirror camera frame with charge coupled device ~CCD! image detectors and is practically fully operated by computer control was constructed. High sensitivity CCDs are used so that image intensifiers, which would degrade image quality, are not necessary. Customized electronics and instruments were used to improve the flexibility and control ...

A cross-reactive array in a micro titer plate (MTP) format is described that is based on a versatile and highly flexible scheme. It makes use of rather unspecific metal ions probes having almost identical fluorescence spectra, thus enabling (a) interrogation at identical analytical wavelengths, and (b) imaging of the probes contained in the wells of the MTP using a CCD camera and an array of bl...
