The phenomenal growth of mobile data demand has brought about increasing scarcity in available radio spectrum. Meanwhile, mobile customers pay more attention to their own experience especially in communication reliability and service continuity on the move. To address these issues, LTE-unlicensed (LTE-U) is considered as one of the latest ground-breaking(More)
Surfactant soil washing can remove polycyclic aromatic hydrocarbons (PAHs) from contaminated soil, and the white rot fungus, Phanerochaete chrysosporium Burdsall in Burdsall & Eslyn, can oxidize PAHs. The objective of this study was to develop a novel bioremediation technology using a combination of abiological surfactant soil washing followed by PAH(More)
Wireless sensor networks (WSNs) play an increasing role in a wide variety of applications ranging from hostile environment monitoring to telemedicine services. The hardware and cost constraints of sensor nodes, however, make sensors prone to clone attacks and pose great challenges in the design and deployment of an energy-efficient WSN. In this paper, we(More)
In this study, an elevated non-ionic surfactant critical micelle concentration (CMC) in a soil/aqueous system was examined. Experimental measurements have been made of surfactant solubilization of polycyclic aromatic hydrocarbons (PAH) (i.e. fluoranthene and pyrene) in a 5-month aged PAH contaminated soil, as well as surfactant sorption onto soil.(More)
An ELISA Microtiter Plate, Total Aflatoxin Test called AgraQuant® was validated to measure total aflatoxins in a range from 4 to 40 ppb in corn, corn meal, corn gluten feed, corn gluten meal, corn germ meal, corn/soy blend, popcorn, sorghum, wheat, milled rice, soybeans, peanuts and cottonseed. The test is performed as a solid phase direct competitive ELISA(More)
Recent advances in micro-electro-mechanical systems (MEMS) technology have boosted the deployment of wireless sensor networks (WSNs). Limited by energy storage capability of sensor nodes, it is crucial to jointly consider security and energy efficiency in data collection of WSNs. Disjoint multi-path routing scheme with secret sharing is widely recognized as(More)
BACKGROUND AND OBJECTIVE Indigenous soil microorganisms are used for the biodegradation of petroleum hydrocarbons in oily waste residues from the petroleum refining industry. The objective of this investigation was to determine the potential of indigenous strains of fungi in soil contaminated with petroleum hydrocarbons to biodegrade polycyclic aromatic(More)
The metabolic responses of the juvenile Miichthys miiuy in terms of oxygen consumption and ammonia excretion to changes in temperature (6–25°C) and salinity (16–31 ppt) were investigated. At a constant salinity of 26 ppt, the oxygen consumption rate (OCR) of the fish increased with an increase in temperature and ranged between 133.38 and 594.96 μg O2 h−1(More)
A mesocosm experiment was conducted to study the effects of commercial microbial agents (probiotics) on the phytoplankton community structure in a shrimp (Litopenaeus vannamei) farm located in Yinzhou-Ningbo, Zhejiang Province, China. Qualitative and quantitative analyses of the phytoplankton were examined along with physico-chemical parameters in the ponds(More)
In this paper, we analyze the user accommodation capabilities of LTE-A systems with carrier aggregation for the LTE users and LTE-A users, respectively. The adopted performance metric is equivalent capacity (EC), defined as the maximum number of users allowed in the system given the user QoS requirements. Specifically, both LTE and LTE-A users are divided(More)
