The REDEEM authoring tool allows teachers to create adapted learning environments for their students from existing material. Kamagra Australia Previous evaluations have shown that under experimental conditions REDEEM can significantly improve learning. The goals of this study were twofold: to explore if REDEEM could improve students learning in real world situations and to examine if learners can share in the authoring decisions. REDEEM was used to create 10 courses from existing lectures that taught undergraduate statistics. An experimenter performed the content authoring and then created student categories and tutorial strategies that learners chose for themselves. https://www.buykamagraaustralia.nu All first-year psychology students were offered the opportunity to learn with REDEEM: 90 used REDEEM at least once but 77 did not. Students… also completed a pre-test, 3 attitude questionnaires and their final exam was used as a post-test. Learning with REDEEM was associated with significantly better exam scores, and this remains true even when attempting to control for increased effort or ability of REDEEM users. Students explored a variety of categories and strategies, rating their option to choose this as moderately important. Consequently, Kamagra Perth Australia whilst there is no direct evidence that allowing students this control enhanced performance, it seems likely that it increased uptake of the system.
To investigate the dose-volume histogram parameters and clinical factors as predictors of pleural effusion in esophageal cancer patients treated with concurrent chemoradiotherapy (CRT); Buykamagraaustralia Forty-three esophageal cancer patients treated with definitive CRT from January 2001 to March 2007 were reviewed retrospectively on the basis of the following criteria: pathologically confirmed esophageal cancer, available computed tomography scan for treatment planning, https://www.buykamagraaustralia.nu 6-month follow-up after CRT, and radiation dose ≥ 50 Gy. Exclusion criteria were lung metastasis, malignant pleural effusion, and surgery. Mean heart dose, mean total lung dose, and percentages of heart or total lung volume receiving ≥ 10-60 Gy (Heart-V(10) to V(60) and Lung-V(10) to V(60), respectively) were analyzed in relation to… pleural effusion; https://en.wikipedia.org/wiki/Sildenafil The median follow-up time was 26.9 months (range, 6.7-70.2) after CRT. Of the 43 patients, 15 (35%) developed pleural effusion. By univariate analysis, mean heart dose, Heart-V(10) to V(60), and Lung-V(50) to V(60) were significantly associated with pleural effusion. Poor performance status, primary tumor of the distal esophagus, and age ≥ 65 years were significantly related with pleural effusion. Kamagra Oral Jelly Wiki Multivariate analysis identified Heart-V(50) as the strongest predictive factor for pleural effusion (p = 0.01). Patients with Heart-V(50).
Highlights • Tomography down to 400km depth under New Madrid Seismic Zone (NMSZ) is obtained. Kamagra Perth A prominent low-velocity zone (LVZ) exists in the lithosphere under NMSZ. • The LVZ can concentrate tectonic stress and transfer stress to seismogenic faults. • NMSZ is related to the structural heterogeneity in the crust and upper mantle. Abstract We determine a 3-D P-wave velocity model of the crust and upper mantle down to 400km depth to investigate structural heterogeneity and its influences on the generation of intraplate earthquakes in the New Madrid Seismic Zone. https://www.buykamagraaustralia.nu We used 4871 high-quality arrival times from 187 local earthquakes and 30,846 precise travel-time residuals from 1041 teleseismic events recorded by the EarthScope/USArray Transportable… Array. Our results show that, beneath the Reelfoot rift, a significant low-velocity (low-V) zone exists in the upper mantle down to 200km depth, with a large volume of 200×200×150km 3 . The origin of the low-V zone may be related to the passage of the Bermuda hotspot and the stalled ancient Farallon slab materials foundering in the mantle transition zone. This low-V zone may have relatively low shear strength and act as a viscously weak zone embedded in the lithosphere, Buykamagraaustralia being apt to concentrate tectonic stress and transfer stress to the seismogenic faults in the upper crust, leading to the large intraplate earthquakes in the New Madrid Seismic Zone.
