Title: Analysis of the decomposition of factors affecting energy-related carbon emissions in Guangxi province, China Authors: Zhou, Huijie; Zou, Yi; Kuang, Yaoqiu; Huang, Ningsheng; Wang, Wenxiu; Wang, Dehui Abstract: Present study also indicated the industrial structure of Guangxi was characterized with high-energy consuming industries since 2004. The rapid urbanization changed the population structure of Guangxi, being a leading driver of carbon emissions, by examining the regional development inequalities in China and Guangxi, this study suggested the governments should develop special policies for creating a pathway towards sustainable, low-carbon development for under-developed minority-inhabited areas rather than setting non-regional differences emissions targets.

Title: Comparative study on condition factors of Terapon jarbua and Terapon puta from Puducherry waters Authors: Nandikeswari, R.; Sambasivam, M.; Mohan, P.M. Abstract: The condition factor values between male and female Terapon jarbua and Terapon puta were examined. Mean values of both the species showed there was statistically slight difference and the difference was in favour of female. From the present study, it is noticed that the K_n values of male and female Terapon jarbua and Terapon puta are greater than one in most of the months in the year 2009-2010. Page(s): 245-249

A novelty location-based routing scheme and dynamically vary the transmit power in deep sound channel of acoustics

Title: A novelty location-based routing scheme and dynamically vary the transmit power in deep sound channel of acoustics Authors: Tsai, Chia-Sheng; Yang, Chich-Fu Abstract: Many papers have examined the current state of underwater sensor networks (UWSN) technologies. The UWSN could be recorded by hydrophones that are suspended in the channel to monitor seismic events on or below the seafloor generated energy that caused by earthquake. In the deep ocean Sound Frequency and Ranging channel, acoustic waves carry the information of seismic events for long range propagation over a few thousands kilometers. In this paper, we present a novel approach of sensor devices as well as routing protocol towards Sound Frequency and Ranging channel for Sound Fixing and Ranging channel technologies. The sound speed increases towards sea surface as water temperature increases. Therefore, we use the oceanography to find a more efficient way of utilizing routing protocol to obtain more effective detection and identification capabilities, and also to dynamically vary the transmit power for underwater sources. We devise a low cost robust routing protocol based on the long-distance transmission Sound Frequency and Ranging channel. The transmission distance can be determined passively by UWSN with minimum control overhead. The routing scheme integrates position and routing functionalities while leveraging different levels to provide high link layer reliability and energy efficient. We developed an algorithm for underwater acoustic power control at different layers of the UWSN signal power which depends on oceanography requirements. Our approach gives a straightforward interpretation of an adaptive location-based routing protocol, which can overcome the location-based UWSN without GPS position. It reduced costs of deployment for the case of long range propagation. The performances are measured according to the number of collisions, energy consumption per bit, and average end-to-end packet latency. The result of simulation is better than other routing protocols such as FBR and static methods. Page(s): 250-258

Coastal vulnerability: A case study along Digha Sankarpur coast, West Bengal, India

2017-03-16T09:15:52Z

Title: Coastal vulnerability: A case study along Digha Sankarpur coast, West Bengal, India Authors: Sen, Sayanti; Sen, Goutam; Chatterjee, Meenakshi Abstract: This study attempts to study the socio-economic impacts of coastal hazards on the vulnerable zone populace, identify the probable factors that are responsible for inducing worst impact and to suggest methods to manage the impact of coastal hazards to reduce damage on the coastline. Analysis has been carried out by preparing a map of the vulnerable coastal stretch and their related threat on coastal habitation. Prediction has been attempted to indicate points of coastal disaster on the study site. Protection option has an effective outcome with consequent degradation and loss of the beach amenity. Within a framework of increasing population pressure and Greenhouse driven climate change, the potential for conflict between development and the coastal processes will surely increase.
