introduction: note taking while attending a ppt requires high activity of memory and writing process which ultimately leads to what is called “death by power point” referring to boredom and fatigue. to overcome this we planned to evaluate the impact of utilisation of uncompleted handouts given prior to ppt presentations. methods: final year mbbs students were divided in 2 batches, batch a and b...

Two gas chromatography-olfactometry (GC-O) techniques were used to screen targeting compounds with an impact on the perceived quality of Sherry vinegar: detection frequency and aroma extract dilution analysis (AEDA). The GC-O study revealed the presence of 108 aromatic notes, of which 64 were identified. Diacetyl, isoamyl acetate, acetic acid, and sotolon reached the highest frequency and flavo...

In this paper we describe our participation in the Interactive Social Book Search task at CLEF 2015. We focus our analysis on differences in search behaviour between native and non-native speakers of English. The analysis is based on both questionnaire and log data. 49 participants out of the 192 total participants are native speakers and the remaining 143 participants are nonnative speakers. I...

background: the inappropriate use of handouts and notes is a common academic problem among students. students' notes are too brief and incomplete in compare with references; hence they may not cover the required content for the courses. the aim of this paper is to analyze students' attitude toward reading handouts and notes instead of references. methods: in this analytical and descri...

These notes are an introduction to the theory of algebraic varieties. In contrast to most such accounts they study abstract algebraic varieties, and not just subvarieties of affine and projective space. This approach leads more naturally into scheme theory. v2.01 (August 24, 1996). First version on the web. v3.01 (June 13, 1998). v4.00 (October 30, 2003). Fixed errors; many minor revisions; add...

We present CheatSheet, a novel contextual interactive memory aid that helps users track their learning progress and refind information when working with complex web applications. Unlike most refinding systems that rely on background monitoring of search sessions or browsing histories to automatically suggest content to users, our approach actively engages users in assessing and curating helpful...

three threidiid spiders of the genus latrodectus occur in khorasan province: l.tredecimguttatus, l.pallidus, l.dahli. the three are described, their diagnostic features are illustrated, and taxonomic notes are given where possible. spider bites are very common in these regions, so, further notes about the medical importance of these species are given. a dichotomic key to the species of the genu...

The objective of this research was to design a 2.4 GHz class AB Power Amplifier (PA), with 0.18um Semiconductor Manufacturing International Corporation (SMIC) CMOS technology by using Cadence software, for health care applications. The ultimate goal for such application is to minimize the trade-offs between performance and cost, and between performance and low power consumption design. This pap...

In this work, dynamic load modulation of high power amplifiers using a varactor-based tunable matching network is presented. The feasibility of dynamic tuning and efficiency enhancement of this technique is demonstrated using a modular design approach for two existing high efficiency power amplifiers (PA), a 7-W class-E, and a 10-W class-J power amplifier PA at 1 GHz. For this purpose and for e...
