A screen capture of a function music teachers wanted for DT (apple.com).

We are living in the 21st century that requires us to know how to integrate paper based curricula into interactive media. The purpose of the study is to provide exemplary cases that music teachers hope for their music classes through using Digital Textbook. For this purpose, two times of interviews with ten music teachers in South Korea were conducted. Case study and grounded theory methodology were adopted as a tool for analyzing the data. As a result, the teachers’ desires for Digital Textbook were categorized into two perspectives: learner-centered learning, and collaborative learning & connection with open sources. Continue reading

Marajó, located in the lower Amazon, Brazil, is one of the largest river islands in the world. Most of the island is subject to tidal or seasonal flooding. Despite its historical, cultural and geographical importance, Marajó Island remains relatively less investigated in terms of mammal diversity, ecology and community structure than the rest of the Amazon. This scenario has motivated the presentation of this list of land mammals of eastern Marajó Island. Two field surveys were conducted in the course of 7-11 December 2012 and 17-25 Continue reading

ABSTRACT

The organs of flowers & leaves etc.
The organs of flowers & leaves etc.

On the investigation of the biodiverisities of plant resources of Nujiang River Valley in Nujiang Autonomous Prefacure, Yunnan Province, China, a new species of Ehretia has been described and illustrated as Ehretia retroserrata in the arid valley of Nujiang according to the new living state of erect shrub and the characteristics of serrate leave margin, retrose, apiculate, endocarp divided at maturity into 4 1-seeded pyrene and serrate leaves margins by comparison with other species of the genus Ehretia.

1. Introduction
There are 14 species in genus Ehretia in China. Most of them are arbors more than 10 meters high. There are 7 species in Yunnan Province and Continue reading

MAC Throughput Improvement Using Adaptive Contention Window

Author(s): Chun‐Liang Lin, Wei‐Ting Chang, Min‐Huei Lu

Abstract
HomePlug AV (HPAV) is a standard developed by HomePlug Powerline Alliance (HPA) for power line communication. In HomePlug AV, it uses a technology named Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) to reduce collision happened in network. However, when network nodes increase, the contention window number may not be wide enough. It will cause collision probability to increase. In this paper, we introduce a new idea of adaptive contention window Continue reading

Human Nail Clippings as a Source of DNA for Genetic Studies

Author(s) :Le Truong, Hannah Lui Park, Seong Sil Chang, Argyrios Ziogas, Susan L. Neuhausen, Sophia S. Wang, Leslie Bernstein, Hoda Anton-Culver

ABSTRACT
Blood samples have traditionally been used as the main source of DNA for genetic analysis. How-ever, this source can be difficult in terms of collection, transportation, and long-term storage. In this study, we investigated whether human nail clippings could be used as a source of DNA for SNP genotyping, null-allele detection, and whole-genome amplification. From extracted nail DNA, we achieved amplicons up to a length of ~400 bp and >96% concordance for SNP genotyping and 100% concordance for null-allele detection compared to DNA derived from matched blood sam-ples. For whole-genome amplification, OmniPlex performed better than Multiple Displacement Amplification with Continue reading

Revisiting WTO Fisheries Subsidies Negotiations

Author(s):Youngjeen Cho

ABSTRACT
Fisheries subsidies negotiation was added to the negotiation agenda of the DDA largely by the concern for the depletion of fishery stocks. Some members, in particular, the Friends of Fish group countries, claimed that over-fishing and overcapacity caused by various fisheries subsidies program have resulted in the depletion of fishery stocks. Therefore, they argued that new disciplines should be introduced to address the situation. In 2007, after more than five years of negotiations, the chairman of the Rules Negotiations Group circulated a consolidated text. However, the negotiations have hardly Continue reading

Propolis in Dogs: Clinical Experiences and Perspectives (A Brief Review)

Author(s):Nelly Tovar Betancourt, Lucila García-Contreras, Tonatiuh Alejandro Cruz Sánchez

ABSTRACT
Propolis in DogsIn light of the scarcity of novel therapeutic agents that are effective, the pharmaceutical industry has found a newer source of therapeutic compounds in natural products and herbal medicine to address the current health problems in humans and animals. What is particularly promising about these agents is that they produce fewer side effects and are more cost effective than synthetic compounds. This means greater availability of these treatments particularly for less developed countries who can’t afford expensive treatments. The reduced side effects also mean greater patient tolerance and increased compliance thereby yielding maximal therapeutic effect without negatively impacting on quality of life. Continue reading

Estimation of Population Ratio in Post-Stratified Sampling Using Variable Transformation

Author(s):Aloy Chijioke Onyeka, Chinyeaka Hostensia Izunobi, Iheanyi Sylvester Iwueze

ABSTRACT
Extending the work carried out by [1], this paper proposes six combined-type estimators of population ratio of two variables in post-stratified sampling scheme, using variable transformation. Properties of the proposed estimators were obtained up to first order approximations,(on–1), both for achieved sample configurations (conditional argument) and over repeated samples of fixed size n (unconditional argument). Efficiency conditions were obtained. Under these conditions the proposed combined-type estimators would perform better than the associated customary combined-type Continue reading

Dual Dynamic PTZ Tracking Using Cooperating Cameras

Abstract

Master-slave camera surveillance setup (refer to gimbals graphically like master and slave).
Master-slave camera surveillance setup (refer to gimbals graphically
like master and slave).

This paper presents a real-time, dynamic system that uses high resolution gimbals and motorized lenses with position encoders on their zoom and focus elements to “recalibrate” the system as needed to track a target. Systems that initially calibrate for a mapping between pixels of a wide field of view (FOV) master camera and the pan-tilt (PT) settings of a steerable narrow FOV slave camera assume that the target is travelling on a plane. As the target travels through the FOV of the master camera, the slave cameras PT settings are then adjusted to keep the target centered within its FOV. In this paper, Continue reading

ABSTRACT
Jatropha curcas is a species with a variety of uses. It is grown primarily for oil for biodiesel, but also has agronomic and medicinal applications. Two methods were evaluated for cryopreservation of seeds and zygotic embryos of J. curcas: desiccation followed by rapid
