Indian Culture and Heritage

The long span of Indian history covering more than 3000 years and enumerating several civilizations has been a constant reminder of the country's rich multicultural extravaganza and world-renowned heritage. The people and their lifestyles, their dance forms and musical styles, art & handicrafts, and such other elements go on to reflect the varied hues of Indian culture and heritage, which truly epitomises the nationality of the country. This section attempts at showcasing all those elements, which act as a window to the culture and heritage of India.

Climate Change Can Grind Down Plate Tectonics

Earth's changing climate has a spectacular ability to reface the planet. Shifting winds and ocean currents can turn rainforests to deserts and back again, while ice ages have covered whole continents in glaciers again and again through time.Now, new evidence has emerged that, given enough time, climate change can even alter the course of plate tectonics.

The march of plate tectonics had previously seemed impervious to water and air's fickle motions. No matter the weather, plates would grind past and crash into one another to build mountain ranges, or sink into the hot depths of the mantle.But, according to Brendan Meade of Harvard University the mighty Andes mountain range, the longest on Earth, might not be here today if it wasn't for a drastic shift in climate 14 million years ago.

McCain Goes On The Attack In Final Debate

John McCain lashed out at Barack Obama's efforts to link him to George Bush's unpopular presidency. "Senator Obama, I am not President Bush. If you wanted to run against President Bush, you should have run four years ago," McCain said. McCain came out fighting last night in what was perhaps his last big opportunity to turn around a campaign less than three weeks before the election, but Obama emerged from the encounter relatively unscathed. McCain's poll numbers have fallen as Americans appear increasingly unwilling to put another Republican in the White House at a time of financial turmoil and fears of a recession. Major U.S. stock market indexes fell nearly 8 percent or more Wednesday. The 90-minute encounter, at Hofstra University outside New York City, had the fireworks lacking in the candidates' first two debates. With the rivals seated at a round table, McCain assailed Obama's character and his campaign positions on taxes, trade, abortion and other issues.

McCain heatedly demanded that Obama explain his relationship with William Ayers, a Vietnam war-era radical. Obama brushed off the attack, saying he was 8 years old when Ayers was involved in anti-war activities, including the bombing of federal buildings. For all of McCain's intensity, it was far from clear that he managed to undermine Obama's growing popularity. The attacks also risked a backlash: Polls have shown that personal attacks by the McCain campaign — including advertisements about Ayers — have backfired, alienating voters at a time that the economy is the overwhelming concern. When McCain talked about Ayers, Obama countered: "The fact that this has become such an important part of your campaign, Senator McCain, says more about your campaign than it says about me." As in the previous two debates, national polls showed a majority of debate watchers rated Obama the clear winner. A CNN/Opinion Research Corp. poll found that 58 percent of those surveyed said Obama did the best job in the debate, with 31 percent saying McCain did better. The poll was conducted by telephone with 620 adult Americans who watched the debate and had a sampling error of plus or minus 4 percentage points.

Obama Cites Gandhi To Back His Call For Change

Calling Mahatma Gandhi's message and significance as universal, US presidential top-runner Barack Obama has said that real change in America "will not come from Washington - it will come when the people, united, bring it to Washington".

A big admirer of Gandhi, whose portrait hangs in his office, Obama issued a statement on the birth anniversary of the great leader, calling upon Americans to "rededicate ourselves, every day from now until November 4 (election day), and beyond, to living Gandhi's call to be the change we wish to see in the world".

Statement from Vice Chair Donetta Davidson

September 24, 2008 -- Last Thursday, September 18, at an all day Public Meeting, the Commission heard testimony from several panelists including Dr. Merle King of Kennesaw State University who offered probably one of the most poignant observations to date. He quoted a Professor from Georgia Tech who said that “voting systems are not rocket science.” Dr. King replied “No, it’s far more complicated.” He used the analogy that states cannot cancel an election in the way that NASA can scrub a launch at any time if the conditions aren’t ideal. Ready or not the election must go on.

Election officials must be ready for everything and anything that may happen. The EAC has devoted a good deal of time and resources on contingency and disaster planning. State officials have also been working overtime to prepare for the record turnout expected. However, budgets were set before all of the excitement surrounded this particular presidential race. Many of the states set their financial expenditure thresholds before they realized that they would need more equipment, supplies and staff to ensure that November 4th runs smoothly.

One of the other panelists, Doug Lewis of the Election Center, mentioned that there have been local officials who have claimed that they do not have sufficient funds to execute this year’s election and have spent less on this upcoming election than on their previous non-presidential elections. It has been suggested that states should reconsider their application of Help America Vote Act (HAVA) funds to help with their financial constraints in order to keep up with the demand for supplies and resources with this next election. However, this is a situation where states need to be very cautious that they are not supplanting state and local funds with federal funds. This idea could possibly be a good solution as long as officials have properly allocated funding to the local level while in compliance with the guidelines that govern how they spend HAVA money. However, if this solution were to be realized it could constitute a “material change” according to our proposed guidelines.

With the comments which were offered at Thursday’s meeting, it highlighted the concerns that I have had with the proposed guidelines on material changes. HAVA §253 requires that states file a state plan and that the chief State election official file a statement certifying that the State is in compliance with the requirements of §253(b). This is problematic, however, as the state plans submitted do not account for any developments or changes in budget due to unforeseen circumstances. HAVA §254(a)(11) addresses this and requires that states “conduct ongoing management of the plan, except that the State may not make any material change in the administration of the plan.” If material changes are made, they must be done in compliance with §254(a)(11)(A)-(C). This brings me to my concern with sections 3 and 4 of the Proposed Guidelines on HAVA §254(a)(11): Material Changes in the Administration of HAVA State Plans. Section 3 requires that if there is a budget change of 10 percent or more of the HAVA fiscal year’s cumulative budget or a change of more than 10 percent of the cumulative budget of the fiscal years requirement payment from one category to another an amended state plan would be required. Additionally, section four states that if there is a revision in the means by which a State plans to achieve the HAVA objectives then an amended state plan must be submitted. If the proposed guidelines are approved, both of these sections would come into play if there were a disaster or emergency of any kind. We all remember how Hurricane Katrina wreaked havoc on the gulf coast and New Orleans. Elections are unique in that we are dealing with tight and inflexible timelines. If the suggestions in our guidelines cannot be met it will discourage the states from either following the guidelines or taking the necessary action when an emergency arises. The southern states and gulf coast know too well that even with a contingency plan, drastic measures have to be taken to meet their critical deadlines. If the proposed guidelines are implemented sections 3 and 4 will be activated if they utilized their HAVA funds to deal with their emergency situation. They would not have time to amend their state plan before taking action.

It is my strong opinion that the EAC should proceed with caution when creating guidelines that we “suggest” they follow. Best practices on how to improve an election are one matter. However, it is a different matter when we start creating guidance that is suspiciously close to regulation. Under HAVA Congress specifically took the notion that the Commission does not have regulatory authority but serves as a clearinghouse of best practices that states could voluntarily utilize.

Microbial biodegradation

Interest in the microbial biodegradation of pollutants has intensified in recent years as mankind strives to find sustainable ways to cleanup contaminated environments. These bioremediation and biotransformation methods endeavour to harness the astonishing, naturally occurring, ability of microbial xenobiotic metabolism to degrade, transform or accumulate a huge range of compounds including hydrocarbons (e.g. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), pharmaceutical substances, radionuclides and metals. Major methodological breakthroughs in recent years have enabled detailed genomic, metagenomic, proteomic, bioinformatic and other high-throughput analyses of environmentally relevant microorganisms providing unprecedented insights into key biodegradative pathways and the ability of organisms to adapt to changing environmental conditions.

The elimination of a wide range of pollutants and wastes from the environment is an absolute requirement to promote a sustainable development of our society with low environmental impact. Biological processes play a major role in the removal of contaminants and they take advantage of the astonishing catabolic versatility of microorganisms to degrade/convert such compounds. New methodological breakthroughs in sequencing, genomics, proteomics, bioinformatics and imaging are producing vast amounts of information.

Enzyme kinetics

Enzyme kinetics is the study of the chemical reactions that are catalysed by enzymes, with a focus on their reaction rates. The study of an enzyme's kinetics reveals the catalytic mechanism of this enzyme, its role in metabolism, how its activity is controlled, and how a drug or a poison might inhibit the enzyme.

Enzymes are usually protein molecules that manipulate other molecules — the enzymes' substrates. These target molecules bind to an enzyme's active site and are transformed into products through a series of steps known as the enzymatic mechanism. These mechanisms can be divided into single-substrate and multiple-substrate mechanisms. Kinetic studies on enzymes that only bind one substrate, such as triosephosphate isomerase, aim to measure the affinity with which the enzyme binds this substrate and the turnover rate.

Pharmacology

After a confirmed test of the anxiolytic efficacy in a mouse model, receptor antagonists haloperidol, mecamylamine, and ketanserin were applied. Haloperidol completely reversed the anxiolytic effects, and mecamylamine and ketanserin nearly completely reversed the effects. This shows that aniracetam's anxiolytic mechanism is facilitated by D2/D3 dopamine, nicotinic acetylcholine, and 5-HT2A receptors.

Aniracetam has also been shown to selectively modulate the AMPA glutamate receptor and was used as the parent compound to derive a class of drugs known as the ampakines which are being investigated as nootropics and neuroprotective drugs for the treatment of Alzheimer's disease and other neurodegenerative conditions.

Despite the fat solubility of aniracetam its half-life is much shorter than common racetam analogs such as Piracetam.

Wide Area Augmentation System

The Wide Area Augmentation System (WAAS) is an air navigation aid developed by the Federal Aviation Administration to augment the Global Positioning System (GPS), with the goal of improving its accuracy, integrity, and availability. Essentially, WAAS is intended to enable aircraft to rely on GPS for all phases of flight, including precision approaches to any airport within its coverage area.

WAAS uses a network of ground-based reference stations (Benchmark DGPSRs transmitting differential corrections (DCs, located within spaces protected from the public inside airportsin North America and Hawaii, to measure small variations in the GPS satellites' signals in the western hemisphere. Measurements from the reference stations are routed to master stations, which queue the received DCs and send the correction messages to geostationary WAAS satellites in a timely manner (at least every 5 seconds or better). Those satellites broadcast the correction messages back to Earth, where WAAS-enabled GPS receiver uses the corrections while computing its position to improve accuracy. The longer any given DC has been delayed, the less benefit it will produce.

The International Civil Aviation Organization (ICAO) calls this type of system a Satellite Based Augmentation System (SBAS). Europe and Asia are developing their own SBASs, the Indian Gagan, the European Geostationary Navigation Overlay Service (EGNOS) and the Japanese Multi-functional Satellite Augmentation System (MSAS), respectively. Commercial systems include StarFire and OmniSTAR.

VersionTracker

VersionTracker.com is a website that tracks software releases. It started out originally as a Mac OS software tracker, eventually expanding into Mac OS X, Microsoft Windows and Palm OS.

VersionTracker does not host the majority of the software listed (it merely links to them), only in special agreements with the developers.

VersionTracker also offers a software called VersionTracker Pro that checks software versions on a user's computer and then queries its database to see if any updates are available. This feature is available only to paid subscribers. Browsing and searching the database is free.

Neogeography

Neogeography literally means "new geography", and is commonly applied to the usage of geographical techniques and tools used for personal and community activities or for utilization by a non-expert group of users. Application domains of neogeography are typically not formal or analytical.

The term and field owes much of its inspiration to the Locative media movement that sought to expand the use of location-based technologies to personal expression and society.

Traditional GIS Geographic Information Systems historically have developed tools and techniques targeted towards formal applications that require precision and accuracy. By contrast, Neogeography tends to apply to the areas of approachable, colloquial applications. The two realms can have overlap as the same problems are presented to different sets of users: experts and non-experts.

Locative media

Locative Media are media of communication bound to a location. They are digital media applied to real places and thus triggering real social interactions. While mobile technologies such as the Global Positioning System (GPS), laptop computers and mobile phones enable locative media, they are not the goal for the development of projects in this field. Rather:

"Locative media is many things: A new site for old discussions about the relationship of consciousness to place and other people. A framework within which to actively engage with, critique, and shape a rapid set of technological developments. A context within which to explore new and old models of communication, community and exchange. A name for the ambiguous shape of a rapidly deploying surveillance and control infrastructure." (Russell, 2004)

Relational model

The relational model for database management is a database model based on first-order predicate logic, first formulated and proposed in 1969 by Edgar Codd.

Its core idea is to describe a database as a collection of predicates over a finite set of predicate variables, describing constraints on the possible values and combinations of values. The content of the database at any given time is a finite model (logic) of the database, i.e. a set of relations, one per predicate variable, such that all predicates are satisfied. A request for information from the database (a database query) is also a predicate.

The purpose of the relational model is to provide a declarative method for specifying data and queries: we directly state what information the database contains and what information we want from it, and let the database management system software take care of describing data structures for storing the data and retrieval procedures for getting queries answered.

Multidimensional database

Multidimensional databases are variously (depending on the context) data aggregators which combine data from a multitude of data sources; databases which offer networks, hierarchies, arrays and other data formats difficult to model in SQL; or databases which give a high degree of flexibility in the definition of dimensions, units, and unit relationships, regardless of data format.

Multi-dimensional databases are especially useful in sales and marketing applications that involve time series. Large volumes of sales and inventory data can be stored to ultimately be used for logistics and executive planning. For example, data can be more readily segregated by sales region, product, or time period.

While many of the major database vendors have recognized and implemented at least a partial solution, most frequently they rely upon a Star schema database design. However, the star design for relational databases can result in "sparse data," or sets of ordered data with large gaps between data entries. While modern database engines use strategies to limit the impact of sparse data sets on query performance, such as compressing large blocks of empty data elements for quicker access, star databases can still present worse performance than other alternatives.

Noosphere

In the thought of Vladimir Vernadsky and Teilhard de Chardin, the noosphere (sometimes spelled nöosphere) can be seen as the "sphere of human thought" being derived from the Greek νούς ("nous") meaning "mind" + σφαίρα (sfaira) meaning "sphere", in the style of "atmosphere" and "biosphere". In the original theory of Vernadsky, the noosphere is the third in a succession of phases of development of the Earth, after the geosphere (inanimate matter) and the biosphere (biological life). Just as the emergence of life fundamentally transformed the geosphere, the emergence of human cognition fundamentally transforms the biosphere. In contrast to the conceptions of the Gaia theorists, or the promoters of cyberspace, Vernadsky's noosphere emerges at the point where humankind, through the mastery of nuclear processes, begins to create resources through the transmutation of elements.

Transport Layer Security

The TLS protocol allows applications to communicate across a network in a way designed to prevent eavesdropping, tampering, and message forgery. TLS provides endpoint authentication and communications privacy over the Internet using cryptography. Typically, only the server is authenticated (i.e., its identity is ensured) while the client remains unauthenticated; this means that the end user (whether an individual or an application, such as a Web browser) can be sure with whom it is communicating. The next level of security — in which both ends of the "conversation" are sure with whom they are communicating — is known as mutual authentication. Mutual authentication requires public key infrastructure (PKI) deployment to clients unless TLS-PSK or the Secure Remote Password (SRP) protocol are used, which provide strong mutual authentication without needing to deploy a PKI.

Trojan horse

In the context of computing and software, a Trojan horse, or simply trojan, is a piece of software which appears to perform a certain action but in fact performs another such as transmitting a computer virus. Contrary to popular belief, this action, usually encoded in a hidden payload, may or may not be actually malicious, but Trojan horses are notorious today for their use in the installation of backdoor programs. Simply put, a Trojan horse is not a computer virus. Unlike such malware, it does not propagate by self-replication but relies heavily on the exploitation of an end-user. It is instead a categorical attribute which can encompass many different forms of codes. Therefore, a computer worm or virus may be a Trojan horse. The term is derived from the classical story of the Trojan Horse.

iPhone

The Apple iPhone has supported Yahoo! push e-mail since the phone's initial release in 2007. Since July 2008 the release of iPhone 2.0 software brings Microsoft's Exchange ActiveSync platform to Apple's handheld thus allowing the iPhone to synchronize e-mail, calendars, tasks and contacts with a Microsoft Exchange Server. The software which will add features commonly found in enterprise mobile devices will be available through iTunes as a free download. MobileMe stores all your email, contacts, and calendars on a secure online server — or “cloud” — and pushes them down to your iPhone, iPod touch, Mac, and PC. When you make a change on one device, the cloud updates the others. Push happens automatically, instantly, and continuously. You don’t have to wait for it or remember to do anything — such as docking your iPhone and syncing manually — to stay up to date.

Robot kit

A robot kit is a special construction kit for building robots, especially autonomous mobile robots.

Toy robot kits are also supplied by several companies. They are mostly made of plastics elements like Lego Mindstorms and the Robotis Bioloid, or aluminium elements like Lynxmotion's Servo Erector Set and the qfix kit.

The kits can consist of: structural elements, mechanical elements, motors (or other actuators), sensors and a controller board to control the inputs and outputs of the robot. In some cases, the kits can be available without electronics as well, to provide the user the opportunity to use his or her own.

Roboticist

A roboticist designs, builds, programs, and experiments with robots. Since robotics is a highly interdisciplinary field, roboticists often have backgrounds in a number of disciplines including computer science, mechanical engineering, electrical engineering, and computer engineering. Roboticists often work for university, industry, and government research labs, but may also work for startup companies and other entrepreneurial firms. Amateur Roboticist is also a growing hobby all over the world.
