Types of Water Treatment:

2005-11-18T14:36:00.000-08:00

Water Conditioners:
This is one of the most efficient water treatment method and the water which comes out from them has low sodium diets .it does not contain Lime scales Water which intakes appliances lasts for a longer period. It increases the efficiency of heat. It also the effectiveness of soap, it retains calcium and it is very good for health, it has low running cost. The disadvantage is that it wont treats any specific hard water problems, which is clearly described in http://www.water-filters-purifiers-softeners.com/.

Water softeners:
The water softeners takes off lime scale, it brings up heating efficiency and it increases the life span of clothes.

Activated carbon water filters:

They are good in removing chlorine from the water and they are also efficient in removing organic efficiency. This filtration does not deal with microbes, sodium, nitrates, fluorides and hardness.Ultraviolet water filters:
These filters have maximum fabrication capacity and they kill 99% of the germs they are passing through. But these filters do not remove dead cells and do not kill other contaminants.

Water Distillers:
Takes away the natural water cycle processes. Distilled Water is very pure and it is free from all the impurities. It has low Filtration Capacity and high running cost.

Electronic maps

2005-10-25T14:35:00.001-07:00

From the 20th century, the indispensable tool of the cartographer has been the computer. Much of cartography, especially at the data-gathering survey level, has been subsumed by Geographic Information Systems (GIS).

Interactive, computerised maps are commercially available, allowing users to zoom in or zoom out (respectively meaning to increase or decrease the scale), sometimes by replacing one map with another of different scale, centred where possible on the same point.

From the computer scientist's standpoint, zooming in entails one or a combination of:

replacing the map by a more detailed one
enlarging the same map without enlarging the pixels, hence show more detail
enlarging the same map with the pixels enlarged (replaced by rectangles of pixels);

The map may also have layers which are partly raster graphics and partly vector graphics. For a single raster graphics image (2) applies until the pixels in the image file correspond to the pixels of the display, thereafter (3) applies.

The word "map" has also been used to describe places within video games, such as SOCOM II: U.S. Navy SEALs and Counter-Strike, that players choose to compete on, as a synonym for level.

Disadvantages

2005-10-25T14:35:00.000-07:00

From the user's point of view:

Can be incompatible with new or replacement hardware or software.

Require care in handling and storage of the files, to avoid damage or loss

From the publisher/author's point of view:

Can in some cases be hacked, or disseminated without approval from the author or publisher.

Not normally a good format choice for works that have extensive and/or large illustrations, such as works in art history, photography, large maps, etc.

e-book Advantages

2005-10-25T14:34:00.001-07:00

Text can be searched, except when represented in the form of images.

Take up little space.

Hundreds (or thousands) may be carried together on one device.
Approximately 500 average ebooks can be stored on one CD
Ebooks may be read in low light or even total darkness, with a back-lit device.
Type size and type face may be adjusted.

Distributed at low cost.

Distributed instantly, allowing readers to begin reading at once, without the need to visit a bookstore.

Simultaneously share book (if networked).

Errors may be easily corrected with downloadable lists of errata or simply with corrected text.

At the moment, ebooks are commonly published by independent publishing houses, which can mean greater editorial and authorial freedom and more room for experimentation.

An inexpensive format for works that require color.

An excellent choice of format for works that benefit from search and cross-reference capabilities, such as dictionaries, reference works, certain kinds of textbooks.

e-book format

2005-10-25T14:34:00.000-07:00

The ebook community has many options when it comes to choosing a format for production. While the average end user might arguably simply want to read books, every format has its exponents and champions, and debates over "which format is best" can become intense.

Format have both advantages and disadvantages.

An ebook can be distributed as a sequence of images, one for each page. In this way, any image format can be used as an ebook format. This method of distribution produces files very much larger than all others, and also has the disadvantage that the user cannot select text, nor can the ebook be read by a screen reader.

RTF (Rich Text Format) files are actually ASCII files with special commands to indicate formatting information, such as fonts and margins.

HTML(Hyper Text Markup Language) is the markup language used for most web pages. eBooks using HTML can be read using a standard browser with no need for special equipment.

Standard Generalized Markup Language Standardized metalanguage for the description of markup languages; a set of rules for using whatever markup vocabulary is adopted. This includes the Text Encoding Initiative (TEI) standard.

e-book

2005-10-25T14:33:00.000-07:00

An ebook is an electronic or digital version of a book. The term is used ambiguously to refer to either an individual work in a digital format, or a hardware device used to read books in digital format.

The term e-text is used for the more limited case of data in ASCII text format, while the more general e-book can be in a specialized file format.

An ebook is commonly bundled by a publisher for distribution (as an ebook, an ezine, or a internet newspaper), whereas e-text is distributed in ASCII (or plain text), or in the case of academic works, in the form of discrete media such as compact discs.

Some users deprecate the second meaning in favour of the more precise "ebook device."

Metadata commonly include details about author, title, publisher, and copyright date; less common are details regarding language, genre, relevant copyright conventions, etc.

Gorilla

2005-10-25T14:32:00.000-07:00

The gorilla, the largest of the primates, is a ground-dwelling herbivore that inhabits the forests of central Africa. There are two species of gorilla, both in the genus Gorilla; each species has two subspecies.

Both species of gorilla are endangered, and have been subject to intense poaching for a long time. Threats to gorilla survival include habitat destruction and the bushmeat trade.

All gorillas share a single blood type, B.

Gorilla culture
A silverback is an adult male gorilla, typically more than 12 years of age and named for the distinctive patch of silver hair on his back A silverback gorilla has large canines that come with maturity. Blackbacks are sexually immature males of up to 11 years of age.

Silverbacks are the strong, dominant troop leaders. Each typically leads a troop of 5 to 30 gorillas and is the center of the troop's attention, making all the decisions, mediating conflicts, determining the movements of the group, leading the others to feeding sites and taking responsibility for the safety and well-being of the troop.

Males will slowly begin to leave their original troop when they are about 11 years old, travelling alone or with a group of other males for 2–5 years before being able to attract females to form a new group and start breeding. While infant gorillas normally stay with their mother for 3–4 years, silverbacks will care for weaned young orphans.

If challenged by a younger or even by an outsider male, a silverback will scream, beat his chest, shake broken-off branches at the intruder, bare his teeth then charge forward. If he is killed by disease, accident, fighting or poachers, the group will split up or be taken over in its entirety by a male descendant or even an unrelated male; there is a strong risk that a new male may kill the infants of the dead silverback.

Bats

2005-10-25T14:31:00.000-07:00

Bats are flying mammals in the order Chiroptera with forelimbs developed as wings. Other mammals, such as flying squirrels or gliding phalangers, can glide limited distances, but only bats are capable of true flight. The name Chiroptera can be translated as Hand Wing, as the structure of the open wing is very similar to an outspread human hand, covered in a membrane.

Though the vast majority of bats are insectivorous, a significant number from both suborders, Megachiroptera and Microchiroptera (see below), have developed the ability to feed on fruits and their juices. Some of the smaller species are important pollinators of some tropical flowers. Indeed, many tropical plants are now found to be totally dependent on them, not just as pollinators, but eating the resulting fruits and so spreading their seeds. This role explains environmental concerns when an exotic bat is introduced in a new setting. Tenerife provides a recent and particularly interesting example here, given the island's unique flora and fauna (much of it vestiges of the ancient continent of Gondwana). In this case, the exotic bat threatening native species is the Egyptian Bat (Roussettus aegyptiacus). In addition, some bats prey on vertebrates. These bats include the Leaf-nosed bats (Phyllostomidae) of central and South America, and the allied family Noctilionidae (Bulldog bats) that feed on fish.

Enemies
Small bats are sometimes preyed upon by owls and falcons. Generally there are few animals able to hunt a bat. In Asia there is a bird, the bat hawk, which specializes in hunting bats. The domestic cat is a regular predator in urban areas; they may catch bats as they enter or leave a roost, or on the ground. Bats will land on the ground for feeding, in bad weather, or due to accidents while learning to fly.

The worst enemies are parasites. The membranes with all their blood vessels are ideal food sources for fleas, ticks and mites. Some groups of insects suck exclusively bat blood, e.g. the bat fly. In their caves the bats are hanging close together, so it is easy for the parasites to infect new hosts.

The most destructive enemy of bats is probably humans, who fear the harmless animal either because of superstition or fear of rabies. Destruction of bat habitat and elimination of their food source (primarily insects) negatively affects the species.
