A dynamic assessment tool was developed and validated using Mokken scale analysis to assess the extent to which kindergartners are able to construct unconfounded experiments, an essential part of scientific reasoning. Scientific reasoning is one of the learning processes happening within science education. A commonly used, hands-on, experimentation task was adapted to dynamically assess the use...

OBJECTIVE Caloric vestibular stimulation (CVS) has traditionally been used as a tool for neurological diagnosis. More recently, however, it has been applied to a range of phenomena within the cognitive neurosciences. Here, we provide an overview of such studies and review our work using CVS to investigate the neural mechanisms of a visual phenomenon - binocular rivalry. We outline the interhemi...

We present the results of a search for cataclysmic variables (CVs) in the Calán-Tololo survey. We detected a total number of 21 CVs, 12 of them are previously unknown objects. Our results suggest that the mismatch between the theoretically predicted sample and the observed one is not due to observational bias but has to be resolved by a revision of the theoretical models. 1. The survey Theoreti...

We describe a code management and distribution system based on tools freely available for the UNIX systems. At the master site, version control is managed with CVS, which is a layer on top of RCS, and distribution is done via NFS mounted file systems. At remote sites, small modifications to CVS provide for interactive transactions with the CVS system at the master site such that remote develope...

Computer Vision Syndrome (CVS) adalah kombinasi masalah atau sekumpulan gejala pada mata akibat aktivitas penggunaan perangkat digital seperti komputer, telepon, dan tablet dengan penglihatan jarak dekat berlangsung secara terus menerus. Pekerja yang menggunakan komputer durasi lebih dari 2-4 jam sehari beresiko mengalami CVS dapat berdampak produktivitas kerjanya. Penelitian ini bertujuan untu...

Language is the chief embodiment of information and it is, therefore, not surprising that in the information age, a new importance should attach to language. The 1980s have been called ‘‘the decade of language.’’ Worldwide the present publication of language tools, such as dictionaries, glossaries, and thesauri, is proceeding at the rate of 500 per month and there now exist over 10,000 vocabula...

Abstract Color assessment of animal source foods was investigated using a computer vision system (CVS) and traditional colorimeter. With the same measurement conditions, color readings varied between these two approaches. The measured by CVS highly similar to actual foods, ranged from 75.0%-100.0% colors, whereas colors read Minolta colorimeter showed non-typical appearances. CVS-obtained were ...

OBJECTIVE Cationic proteins found in cervicovaginal secretions (CVS) are known to contribute to the early antiviral immune response against HIV-infection in vitro. We here aimed to define additional antiviral factors that are over-expressed in CVS from female sex workers at high risk of infection. METHODS CVS were collected from Kenyan HIV-seronegative (n = 34) and HIV-seropositive (n = 12) f...

purpose: to evaluate the knowledge and practice of computer users about computer related eye problems.  methods: one hundred twenty-three computer users were asked to complete a questionnaire. in each questionnaire, after initial demographic questions, 9 questions were conducted to evaluate the knowledge of the users and 9 questions to assess their attitude about the computer vision syndrome (c...

We present an observational and theoretical review of the winds of cataclysmic variables (CVs). Specifically, we consider the related problems of the geometry, ionization state, and mass-loss rate of the winds of CVs. We present evidence of wind variability and discuss the results of studies of eclipsing CVs. Finally, we consider the properties of accretion disk wind and magnetic wind models. S...
