The aim of Green Cloud Computing is to achieve a balance between resource consumption and quality of service. In order to achieve this objective and to maintain the flexibility of the Cloud, dynamic provisioning and allocation strategies are needed to manage the internal settings of the Cloud, addressing oscillatory peaks of workload. In this context, we propose strategies to optimize the use o...

BACKGROUND Green tea has shown the role of chemoprevention for cancer. Recently, several studies suggested that green tea intake may have effect on esophageal cancer risk, whereas the results were inconsistent. METHODS We performed a meta-analysis of all English and Chinese language studies of green tea consumption and esophageal cancer risk indexed in Medline, Embase, the Science Citation In...

This study was performed to assess the relationship between the amount of green tea that is consumed and periodontitis. It is based on data obtained from the Korea National Health and Nutrition Examination Survey, conducted between 2008 and 2010. A community periodontal index equal to code 3 was defined as moderate periodontitis, and code 4 was defined as severe periodontitis (n = 16,726). Cons...

− Energy consumption of massive scale mobile cloud data centers is increasing unacceptably. It is the most challenging field of concern these days. So there is a need to improve the energy efficiency of such data centers using server consolidation which aims at minimizing the number of active physical machines in a data center. As the analysis has shown that by applying suitable optimization po...

Recently, green networks are considered as one of the hottest topics in Information and Communication Technology (ICT), especially in mobile communication networks. In a green network, energy saving of network nodes such as base stations (BSs), switches, and servers should be achieved efficiently. In this paper, we consider a heterogeneous network architecture in 5G networks with separated data...

ISSUE ADDRESSED Populations in many developed countries continue to fail to meet vegetable consumption recommendations despite ongoing health promotion activities supported by public health policies. Novel ways to encourage vegetable consumption may help address this concern. The aim of the present study was to describe female consumers' perceptions about leafy green vegetables and identify con...

Nowadays, the high power consumption of data centers is the biggest challenge to making cloud computing greener. Many researchers are still seeking effective solutions to reduce or harvest the energy produced at data centers. To address this challenge, we propose a green cloud infrastructure which provides security and efficiency based on energy harvesting (EH-GC). The EH-GC is basically focuse...

CONTEXT Green tea polyphenols have been extensively studied as cardiovascular disease and cancer chemopreventive agents in vitro and in animal studies. However, the effects of green tea consumption in humans remain unclear. OBJECTIVE To investigate the associations between green tea consumption and all-cause and cause-specific mortality. DESIGN, SETTING, AND PARTICIPANTS The Ohsaki National...
