We compared high school students’ performance in a traditional comprehension assessment requiring them to identify key information and draw inferences from single texts, scenario-based (SBA) integrate, evaluate apply across multiple sources. Both assessments focused on non-academic topic. Performance the two were moderately correlated (r = 0.57), but SBA was more difficult (Study 1; n 342). The...

In the laboratory diagnosis of pharyngitis, results from latex agglutination tests (LAT) performed directly on throat swabs are often compared with the isolation of group A beta-hemolytic streptococci (GABHS) from simultaneously obtained swabs cultivated on a variety of media under different atmospheric conditions. In this study, results of an LAT, Directigen, were compared with those of two di...

In this paper, a novel technique for the design of two-channel Quadrature Mirror Filter (QMF) banks with linear phase in frequency domain is presented. To satisfy the exact reconstruction condition of the filter bank, low-pass prototype filter response in pass-band, transition band and stop band is optimized using unconstrained indirect update optimization method. The objective function is form...

Catalytic materials bearing multiple sulfonic acid functional groups and positioned at varying distances from one another on the surface of mesoporous solids are prepared to explore the effects that the spatial arrangement of active sites have on catalytic activity and selectivity. A series of organosiloxane precursors containing either disulfide or sulfonate ester functionalities (synthons of ...

news & views Nevertheless, a few hurdles must be overcome before SBA dielectrics will make a significant impact on large-scale transistor manufacturing. Perhaps the biggest problem at the moment is the slow response of the sodium ions to an external electric field. Consequently, the capacitance of the SBA films is reduced at higher frequencies. Solid-polymer electrolytes typically suffer from a...

Having received considerable interest in recent years, associative classification has focused on developing a class classifier, with lesser attention paid to the probability classifier used in direct marketing. While contributing to this integrated framework, this work attempts to increase the prediction accuracy of associative classification on class imbalance by adapting the scoring based on ...

Repeated applications and combination of glyphosate-containing herbicides (GCH) with other are two weed management practices (WMP) used to compensate for GCH decreasing efficiency impacts in field crops. These may have serious on soil functions because affect biota biological activity (SBA). Two experiments, one corn soybean crops, were conducted during growing season. SBA indicators, respirati...

Magnetic Fe-SBA-15 mesoporous silica molecular sieves were prepared, characterized, and used for magnetic separation. Wet impregnation, drying, and calcination steps led to iron inclusion within the mesopores. Iron oxide was reduced to the metal form with hydrogen, and the magnetic Fe-SBA-15 was obtained. Fourier-transform infrared spectroscopy confirmed the preparation process from the oxide t...

Amniotic band sequence (ABS) is the term applied to a wide range of congenital anomalies, most typically limb and digital amputations and constriction rings, that occur in association with fibrous bands (1). These alterations may be associated or not with cutaneous and visceral abnormalities. This work, which is a literature review, examines several studies that relate to cases of amniotic band...
