A large fraction of atmospheric aerosol particles are formed from condensable vapors in the air. This particle formation process has been observed to correlate in many locations with the sulfuric acid concentration, but the very first steps of cluster formation have remained beyond the reach of experimental investigation until recently. Charged clusters can now be detected and characterized sta...
The purpose of the research is modeling the relationship between divided attention and working memory in mathematical reasoning with the mediation of mathematical knowledge and fluid intelligence in fourth grade elementary students. Statistical population of the research included all fourth grade male students of Primary schools in District 4 of Qom from which 213 students were randomly selecte...
We report cross-shore profile evolution at Palanga, eastern Baltic Sea, where short period waves dominate. Cross-shore studies began directly after a significant coastal erosion event caused by storm “Anatol”, in December of 1999, and continued for year. Further measurements were undertaken sixteen years later. changes described, transport rates calculated. A K-means clustering technique was ap...
The floor of the fourth ventricle in the mouse was studied by scanning and transmission electron microscopy. 1. The fourth ventricular floor is covered by a simple layer of ependymal cells, the cytoplasm of which is characterized by numerous filaments and scanty ribosomes. 2. The ventricular surface of the ependyma is studded with numerous cilia and abundant microvilli. In the medial part of th...
SSI-4: Stuttering Severity Instrument – Fourth Edition is a reliable and valid norm-referenced stuttering assessment that can be used for both clinical and search purposes. It measures stuttering severity in both children and adults in the four areas of speech behavior: (1) frequency, (2) duration, (3) physical concomitants, and (4) naturalness of the individual’s speech. Frequency is expressed...
