The U.S. Spallation Neutron Source (SNS) is an accelerator-based, pulsed neutron-scattering facility currently in the process of ramping up neutron production. To meet present and future beam current and reliability requirements we are developing an RF-driven, H ion source based on a ceramic aluminium nitride (AlN) plasma chamber surrounded by an external RF antenna. This report recounts the de...

Few studies have considered the personal characteristics that may predict the use of Social Networking Sites (SNSs). We examined the prediction of SNS use from distinct personality traits (i.e., sociability and shyness), attitudes toward SNS use, motivations for SNS use and Internet self-efficacy. Participants were 352 Chinese college students who used the QQ zone. Results indicated that sociab...

A representative sample (n=1,000) of the Belgian population aged 18 years and older filled out an online questionnaire on their Internet use in general and their use of social networking sites (SNS) in particular. We measured total time spent on the Internet, time spent on SNS, number of SNS profiles, gender, age, schooling level, income, job occupation, and leisure activities, and we integrate...

We report on the technical design and expected performance of a 592 kg heavy-water-Cherenkov detector to measure absolute neutrino flux from pion-decay-at-rest source at Spallation Neutron Source (SNS) Oak Ridge National Laboratory (ORNL). The will be located roughly 20 m SNS target with better than 5% statistical uncertainty in 2 years. This heavy-water serve as first module two-module system ...

Privacy policies are unsatisfactory in communicating information to users. Social networking sites (SNS) exemplify this, attracting growing concerns regarding their use of personal data, whilst lacking incentives to improve their policies. Standardization addresses many of these issues, but is only possible if policies share attributes that can be standardized. This investigation assessed the s...

UNLABELLED The purpose of this study was to examine the clinical usefulness of preoperative lymphoscintigraphy (PLS) for sentinel node identification in patients undergoing lymphatic mapping during surgery for early cervical cancer. PATIENTS AND METHODS Day-before PLS was performed in 42 patients who were candidates for open radical hysterectomy and intraoperative lymphatic mapping, using a c...

In light of the analysis framework including Political and governmental support, Economical and commercial support, Social and communities support and Technology support (PEST), this study identified motivations and obstacles for seniors’ use of social network services (SNS). Scenario simulation interviews based on four steps in which the seniors built strategies for learning about social media...

As the use of social network sites (SNS) has become increasingly prevalent, its effect on sustainable performance has received much attention. The existing literature has taken either a positive or negative view of SNS, arguing that it either decreases performance by taking time and effort away from work, or increases performance by providing social benefits for enhancing performance. In contra...

Social network sites (SNS) have rapidly become very popular, challenging even the major portals and search engines in terms of usage and commercial value. This chapter introduces key SNS issues and reviews relevant academic research from sociology, communication science, computer science, and information science. The chapter introduces a broad classification of SNS friendship and demonstrates t...

Synaptoneurosomes (SNs) are obtained after homogenization and fractionation of mouse brain cortex. They are resealed vesicles or isolated terminals that break away from axon terminals when the cortical tissue is homogenized. The SNs retain pre- and postsynaptic characteristics, which makes them useful in the study of synaptic transmission. They retain the molecular machinery used in neuronal si...
