Search Engine Traffic Guide
Harvester is a meta search engine for gene and protein information. It searches 16 major databases and prediction servers and combines the results on pregenerated HTML pages. In this way Harvester can provide comprehensive gene-protein information from different servers in a convenient and fast manner. The Harvester search engine works similar to Google, offering genome-wide ranked results at very high speed. Here we describe how to use this bioinformatic tool along with selected examples. The continuously growing amount of gene and protein associated information spread over numerous databases worldwide makes it difficult to find and evaluate relevant information of the genes or proteins of interest. Some databases provide small amounts of manually generated but high quality data, others offer genome wide annotations that have been generated automatically. To obtain the most comprehensive knowledge on the genesproteins under view, it is essential to combine and compare the information...
Internet As Sentinel Iii Monitoring Usage Of Health Websites And Healthrelated Queries To Search Engines
The conventional industry measure of Internet utilization is the number of hits'' to a website from some region for some period (or the number of searches received by a search engine). To detect increases in Internet utilization by sick individuals against a background of extremely high levels of utilization for other purposes, more specific measures of Internet utilization will likely be necessary measures such as the number of requests to a health-related website for documents about influenza or the number of queries to Internet search engines that include the word fever.''
About half of people who use the Internet to access health information online do so via a search engine thus, monitoring the queries received by search engines is a potential biosurveillance strategy. A rapid increase in the number of Google searches containing the word fever'' would be of concern in the absence of a known outbreak or other explanation. In contrast to website monitoring, monitoring of queries to the three most popular search engines would catch nearly 80 of the health-related searches issued over the Internet, assuming that people do not switch to less commonly used search engines for health-related searches. Privacy policies of the search engines (and websites) are, however, a barrier to developing a system to monitor query data from search engines. Organizations that operate search engines (and websites) respect the rights of individuals to confidentiality and have strict policies concerning the distribution and use of personal information. There are...
An Internet search engines is a computer system that (1) locates and indexes web pages, and (2) processes queries from users who are searching for information on the web. The most common way people find information on the Internet is through a search engine (PEW Internet & American Life Project, 2004). A search engine comprises three components a web spider, a database, and one or more information retrieval algorithms. The web spider (also known as a web crawler'') searches the Internet for new web pages (Gordon and Pathak, 1999). It systematically follows hyperlinks found on known pages. If the spider comes upon a web page it has not previously encountered, it sends this page to the information retrieval algorithms for indexing and storage in the database (Kirsanov, 1997). The indexing enables the search engine to retrieve the URL of the web page from the database based on query terms entered into the search engine by users of the search engine. Information retrieval algorithms are...
Ofnitrogen oxides and sulfur dioxide from industry and from heating and traffic sources were estimated, using a combination of models and monitoring data. Controlling for age, smoking habits and length of education, the adjusted risk ratio for developing lung cancer was 1.08 (95 CI 1.02-1.15) per 10-pg m3 increase in average concentration of nitrogen oxides at a home address between 1974 and 1978. The corresponding figure per 10-pg m3 increase in sulfur dioxide was 1.01 (95 CI 0.94-1.08).
Traffic contributes substantially to PM and ozone pollution and to population exposure, but precisely quantifying transport's contribution to total exposure and its adverse effects are still difficult tasks. The review presented in this book clearly identifies the hazardous nature of transport-related air pollution, but also presents a variety of factors that may affect exposure and the attribution of the observed adverse health effects to pollution from traffic sources.
'Because Web addresses (URLs) may change, the reader is advised to use a search engine like Google (http www.google.com ) to access the Web pages mentioned in this chapter. In the present case, typing Web Experimental Psychology Lab into the search field will return the link to the laboratory as the first listed result. The Web Experimental Psychology Lab can also be accessed using the short URL http tinyurl.com dwcpx
Of contributions from different local pollution sources and people's behaviour. Several studies show that air pollution from traffic is higher in urban areas than in rural or non-urban areas. These studies calculated exposures using data from personal and microenvironmental monitoring, often based on passive samplers (Linaker et al., 1996 Raaschou-Nielsen et al., 1996), dispersion modelling (Oosterlee et al., 1996) and GIS-based methods (Jensen et al., 2001 Kousa et al., 2002). Studies related specifically to carbon monoxide, VOCs, PM and metals from traffic sources, however, are uncommon. Moreover, differences in the classification of sampling stations used by various monitoring networks or of personal measurements of selected individuals can underestimate the range of exposure between urban and rural locations. Separating the contribution from transport in most of these situations is difficult, though some indication of the influence of local traffic sources can be gleaned by...
The world and directories of physicians and other professionals who provide cancer services and organizations that provide cancer care. The American Cancer Society Web site has a clinical trials information and matching service that is available via the ACS Web site, (enter find a clinical trial in the site's search engine) and the ACS cancer information center (1-800-ACS-2345). This application identifies clinical trials most likely to be relevant to each patient, based on clinical information entered by that patient. The database includes all trials in the PDQ system, plus additional institutional and pharmaceuical trials.
The ACS Web site () contains general information and specific information about testicular cancer, accessed by using the search engine of the site. Patients can review their specific treatment circumstances by using the Cancer Profiler tool provided by the site. The site also provides many other resources for general issues of cancer, and access to the Cancer Survivors Network, an online community created for and by cancer survivors and their loved ones. Similar information and services are also available 7 days a week 24 hours a day, through the ACS telephone information center (1-800-ACS-2345).
The information presented here is purposefully simplistic. An elaborate explanation of flow cytometry is not appropriate for the audience and tone of this text. Flow cytometry is a specialty technique and a recent Google search listed 10 pages of entries referring to certificate programs for this specialty. For additional information, the student is referred to
Measure to improve the S N ratio is to increase the data acquisition time, since the S N ratio improves in proportion to the square root of acquisition time. Figure 6.10 shows this basic principle with the example of an MS MS spectrum that was acquired for different time intervals. For demonstration of the improvement achieved, the acquired raw MS MS spectra data were used for protein database interrogation via the search engine Mascot.
2 In fact, the current edition of the Oxford English Dictionary (OED) does not define the word biosurveillance. although it is in widespread usage, as evinced by Google search results (13,000 hits on May 8, 2005) as well as its routine use by government agencies, politicians, journalists, and academics. There is no doubt that biosurveillance has been inducted into the common vernacular. Even those without technical expertise or training in the field understand the term intuitively, just as they understand the meaning of bioterrorism, another word currently left undefined in the OED. The absence of a standard definition reflects the need to synthesize the multidisciplinary work being done in the field. Indeed, this book is our effort to present a unified approach to and understanding of biosurveillance.
This very public and reluctant coalition of a government-sponsored, transnational scientific program and a biotechnology industry heavyweight is just one node in a wide-ranging, heterogeneous network of human and nonhuman actors that constitutes genetics-in-action (pace Latour 1987 cf. Flower and Heath 1993 Heath I998a,b). The knowable, manipulable human genome also belongs to health advocates living with particular heritable diseases, who raise research funding and run on-line forums (Heath et al. 1999 Taussig, Rapp, and Heath, chapter 3, this volume). It belongs to scientists in Japan, China, the United Kingdom, France, and Germany, as well as to DNA donors (voluntary or not) from Iceland and the Amazon. And it is the province of essential nonhuman players, from centralized sequence databases and their search engines to genetically modified organisms (GMOs). Genomes, human and other, are dynamic, emergent entities still under negotiation as territory, property, soul, medical...
The scope of the Internet can make doing research a frustrating task. Before listing resources, a primer of web-based research is offered. The first step in web-based research is to find a search engine directory you are comfortable using. A search engine directory is a website tool that allows users to find information on the World Wide Web (WWW). The primary problem that most people encounter when searching the web is encountering too much information, as there are millions upon millions of websites. There are several types of search engines directories that can be utilized. Search directories are databases arranged in a hierarchical database that reference websites. The websites that are listed are chosen by individuals and classified according to the rules of that particular search directory. The Yahoo Directory is the classic example of a search directory. These are good when you only have a general idea of what you are looking for, as subjects are divided into broad categories...
In March 2001, the National Institutes of Health issued the following warning The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading. 1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with heart disease is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about heart disease, using the most advanced research tools available and spending the least amount of time doing so.
Http www.cdc.gov home site for the Center for Disease Control and Prevention. It has a search engine in the top right hand corner for specific searches. It covers information from birth defects, diseases, emergency preparedness, vaccinations, etc. http www.nih.org home site for the National Institutes of Health. Search engine includes the National Library of Medicine.
The physical Internet comprises the wires, optical fiber, satellites, protocols, and routing computers (what a technologist would consider the Internet). Examples of the software applications include e-mail programs, web servers, search engines, instant messaging programs, and file transfer programs. In this chapter, we use the term Internet'' to refer to both the physical Internet and the software applications that run on it.
Additionally, integration of GEO data into NCBI's Entrez search engine greatly expands the utility of the data. Entrez is a powerful tool that enables disparate data in multiple databases to be richly interconnected. This can lead to inference of previously unidentified relationships between diverse data types, facilitating novel hypothesis generation, or assisting in the interpretation of available information. Such opportunities for discovery will only increase as the database continues to grow.
The time this book spent in development spanned several years. In that time, changes in usage occurred with respect to the primary subject matter of this book namely, the apparent delay in the normative acquisition of skills and knowledge by human beings. This condition, this outcome of human development, has been called mental retardation (MR) for the better part of the last century in North America. Scholars and researchers will need to use this terminology for the foreseeable future instead of ID as a search term in research and bibliographic search engines. The technical definition of this cognitive and developmental disability is still referenced against MR in the major diagnostic coding systems used worldwide, and the generally accepted defining characteristics of the condition remain significantly subaverage general intelligence and adaptive behavior as measured psychometrically, and that first occurs during the developmental period (see...
A scheme highlighting the major steps of the protocol is shown in Figure 1. Tuschl and colleagues have shown that the anti-viral, interferon response that cells develop when exposed to long, double-stranded RNAs is obviated by using shorter duplexes of 21 to 23 nucleotides including 3-prime overhangs of two nucleotides at both ends (Elbashir et al., 2001). Online search engines are available for mining transcript sequences in order to identify appropriate duplexes (in both coding as well as untranslated regions). These include the siRNA Selection Program at the Whitehead Institute for Biomedical Research (Cambridge, Massachusetts) (http jura.wi.mit.edu siRNAext ) (Yuan et al., 2004). The sequence of the final core siRNA duplex should be AAGN18TT. Three distinct siRNA sequences are preferable for each mRNA target though experiments using fewer remain worthwhile (see below in troubleshooting).
