At the beginning was Light. Light - pure, distilled, triumphant and overwhelming in its unity and possibilities. Out of this Light came everything that we call Cosmos, Universe and Life. The story of the Universe is the story of the evolving Light, which is intertwined with Love. Love is not accidental but essential to the story of the Universe. Equally essential are sacred symbols, thinking and art. The story of the Universe is enthralling, fascinating, mysterious and yet simple. We need to have the eyes to see the beauty and the genius of Life, as it incessantly re-creates and transforms...
This application note describes the design principles and the circuit operation of the
800VA pure Sine Wave Inverter. The pure Sine Wave inverter has various applications because of its key advantages such as operation with very low harmonic distortion and clean power like utility-supplied electricity, reduction in audible and electrical noise in Fans, fluorescent lights and so on, faster, quieter and cooler running of Inductive loads like microwaves and motors.
This is very convenient and the ready access to the Internet in all first-world
countries, coupled with the cost savings from closing bank branches, is driving
the deployment and adoption of these services. Purely online transactions, however,
lead to increased risk. None of the normal safeguards of real-world transactions
are present. Conversely, risk to the criminals is a lot lower (the attacker can
be in a completely separate jurisdiction from all the other parties in the transaction)
and the retailer sees nothing but a faceless, nameless connection providing
Automobile electrical and electronic systems to explain their detailed operation. The intention is to describe briefly how the circuits work and, more importantly, how and where they may be utilized in vehicle applications. The circuits described are examples of those used and many pure electronics books are available for further details. Overall, an understanding of basic electronic principles will help to show how electronic control units work, ranging from a simple interior light delay unit, to the most complicated engine management system.
An effective separation method of very pure binder fraction to assess radiocarbon dating is
proposed in the present contribution. The elimination of contaminant error sources and the
suitable selection of mortar samples enable the reliable dating. Petrographic analysis under
polarizing light microscopy is used to identify different mineralogical phases of mortar
samples, aggregate nature, and the limestone fragment remains.
And then there was light – a lightweight database! How often have we all wanted some
database that was "just a data store"? Sure, you can use it in many complex ways but in
the end, it's just a plain simple data store. Welcome MongoDB!
And then there was light – a lightweight language that was fun to program in. It supports all
the constructs of a pure object-oriented language and is fun to program in. Welcome Ruby!
Both MongoDB and Ruby are the fruits of people who wanted to simplify things in a complex
world. Ruby, written by Yokihiro Matsumoto was made, picking the best...
It is exactly this shift from denotation to connotation and obtuse meaning, or –
to put it differently – from information to sensorial and affective qualities that is
the topic of this discussion. In the luxury domain in recent years, a certain type
of advertisement has emerged that relies almost exclusively on the evocation
of pure sensations. Only in part do the depicted scenes, characters or objects
lead to these sensations. Rather, the aesthetic features of style – such as depth
of field, diffusion, colour or light – enhance the spectator’s sensorial response.

Study on the visible-light-induced photokilling effect of nitrogen-doped TiO2 nanoparticles on cancer cells
Zheng Li1, Lan Mi1*, Pei-Nan Wang1 and Ji-Yao Chen2
Abstract Nitrogen-doped TiO2 (N-TiO2) nanoparticles were prepared by calcining the anatase TiO2 nanoparticles under ammonia atmosphere. The N-TiO2 showed higher absorbance in the visible region than the pure TiO2.
Mercury has a number of unique and fascinating properties. It is the only metal that, in
its pure form, is a liquid at room temperature. Liquid mercury is volatile, meaning that
it evaporates easily to form a poisonous vapour. Mercury conducts electricity and expands
at a constant rate in response to changes in pressure or temperature. Electrical switches,
barometers and thermometers take advantage of these properties.
The instance of the electric light may prove illuminating in this
connection. The electric light is pure information. It is a medium
without a message, as it were, unless it is used to spell out some
verbal ad or name. This fact, characteristic of all media, means that
the "content" of any medium is always another medium. The content
of writing is speech, just as the written word is the content of print,
and print is the content of the telegraph. If it is asked, "What is the
content of speech?," it is necessary to say, "It is an...
