Forensic acquisition on MP3 players

SummaryDuring autumn migration, people set trammel nets along most of the Mediterranean coast of Egypt, with migrating Common Quail Coturnix coturnix as their primary target. These nets capture large numbers of quail, but also illegally capture other birds, which are then killed. We present the results of surveys from 2008 to 2012 along these lines of nets on the coast of North Sinai, Egypt. In desert scrub, which covers most of the Sinai coast, the mean number of quail killed reached a high of 357.1 per km per day in 2012, with a grand mean over the study period of 191.9 per km per day. Trammel nets also captured 54 other bird species in 28 families. Species captured at the highest rates in desert scrub included Corncrake Crex crex, Isabelline Wheatear Oenanthe isabellina and Greater Short-toed Lark Calandrella brachydactyla. Based on mean rates of capture from 2008 to 2012 in desert scrub and sand bar habitats, we estimate 2.0 million quail and 0.5 million birds of other species are killed annually in North Sinai during the 45 days of peak migration. In 2012, however, after the use of MP3 players to attract quail became widespread, we estimate that 3.3 million quail and 0.5 million other birds were captured. Hunters near the coast have recently begun covering shrubs and trees with mist nets to catch passerines. From 2010 to 2012, mist nets along our survey routes caught birds of 17 species in three families, with seven of these species caught only in this type of net. Hunting is likely to be a contributing factor to population declines for some species that migrate across Egypt and further studies of migratory bird hunting along the southern Mediterranean shore are badly needed.

Aims and Objective. Pain is a common problem associated with postoperative orthopedic patients; the current study is aimed at evaluating music intervention as an alternative method to control pain. Methodology. The experimental design of the current study was comparative, descriptive, and quasi-experimental. 38 postoperative orthopedic patients were equipped with pocket-size MP3 players with prerecorded music tracks (instrumental and lyrical) in Hindi, English, and Urdu. After that, pre-post-pain scores were recorded with the help of designed brief patient logs. Ultimately, a satisfactory survey was completed at discharge. Major Findings. It was found that during the intervention of music, the pain was significantly reduced from 5.40 to 2.98. There was a slight relationship between listening time and pain relief. It was also found that the feedback was extremely positive and each patient suggested the use of music to others with 96.6% recommendation. Conclusion. From the current study, it was found that music intervention can be beneficial to postoperative patient pain control. Further, it is hoped that the findings of the current experimental work will lead to improvements in the care of postoperative patients.

The paper discusses the effect of mobile learning on students, especially the tablets and smartphones. Theses gadgets have become a research interest of education to encourage and facilitate learning. Mobile devices assist in build closer connection between students and teachers. There are several options of mobile devices such as Ipod, personal digital assistant, smart phone, laptop or tablet PC, MP3 Players, pen drive and so on. Mobile learning involves the use of mobile technology either alone or combination with other information and communication technology (ICT). The benefits of mobile learning expand the reach and quality of education, facilitate personalized learning, power anytime, anywhere learning, provide immediate feedback and assessment, ensure productive use of time spent in classrooms, build new community of students, support selected learning, enhance seamless learning, bridge formal and informal learning, improve communication and administration, maximize cost efficiency and update policies related to mobile learning. It is concluded that the benefits overshadow the challenges. Using mobile devices allow students to extend learning beyond the classroom walls. Students are highly engaged and are able to demonstrate unique and creative way to respond to the use of technology that offers some distinctive affordance to users.

E Learning

Mobile learning or “m-learning” is a relatively new learning modality in higher education and it refers to the delivery of educational content by means of mobile devices, such as PDAs, cell phones, and MP3 players, effectively enabling learners to access course materials anytime, anywhere, and any while (Walker, 2006). M-learning is also characterized as “personalized” … “bite-sized”, and “portable”, characteristics not often associated with “conventional tethered e-Learning” (Traxler, 2007).

To achieve better MP3 audio output quality, this thesis makes research of D/A chips that most MP3 players to ultimately make the decision of using one-bit DAC as the way of DAC and audio output. And this overall design scheme is given out as well. Decoding MP3 files through upper computer software of PC and transmitting data to one-bit DAC module through serial ports. DAC is realized in FPGA chip through Verilog Language. And high shelf is used in the output section of one-bit DAC module. Finally, analyzes the output audio frequency of one-bit DAC module, surveys general performance of the overall play system and DAC module.[1][2]
