Healthy well-stocked tropical aquarium, and color can add life to any room in your home or business. Stocking tank properly, it can be difficult. Time, size and choice: we are looking for your tropical aquarium staff for safe and efficient use of stock tanks and there are three principles to be.
Synchronization
This takes time to create a good and healthy aquarium. To add a new fish tanks, especially in people dying too fast may cause some or all. Fish waste contains ammonia and nitrite can be rapidly built and fish kills. Fortunately, the waste will decompose and bacteria grow naturally in aquariums. This bacteria is important for sufficient time to settle before adding the fish too. The first two or three-resistant fish. Test your water for nitrates and ammonia. Level drops to almost zero wait before adding more fish. Remember, this is the waste of fresh fish every time you move will peak. Gradually, the fish in two weeks, but a few times, add the tank health.
Size
It is important to avoid overstocking your tropical aquarium. Very much smaller area, filtration systems, ecosystems and human populations can cause problems for capacity. Tank is full, the tank’s natural bacteria break down fish waste is not effective. This can lead to sick or dying fish. Another danger is not enough oxygen in the overflow tank. Your Fish breathe oxygen dissolved in water. The absorption of oxygen for more than a large tank of water. The basic rule is: one inch of fish per gallon of water. If this twenty-liter tank, means fish about eight inches.
Some fish, for example, male Bettas so aggressive they should be protected. Invasive species are often beautiful, but before sending it to the tank with other fish that get along well. Selection can help calm a very docile fish aquarium. Together with a choice of fish, plants, ornaments, or shelters, large stones are usually a good idea. Provides an additional view of this aquarium, but also less aggressive fish will attack not only a place to hide.

Found in national parks and federal levels, as a rule, field maps in booklet form. Field maps have the same functions as lists. Checklists or field maps for the location map showing the locations where the birds are found on sidewalks, swimming pools and background information on the site.
Birding lists of tool used for bird watchers best bird-watching, and it is a very good tool for a list of bird observations. Life is a tool list, which lists the names of birds, birders happened since the beginning of his experience includes birds. An experienced bird watcher, a list of life, a total of 300-500 species of birds. Beginner builds a list of life by focusing on adding a few species to the list.
Checklist contains information about the collection of birds on the site. This information includes the status, wealth, and the seasonal appearance. Birds found on the site are accidental. Birds are divided on the cards according to their seasonal appearance. Summer season from June to August and the abbreviation “Su” or “s.” In the winter from December to February with the symbol «W» the case from September to November and abbreviated “F.”
Life lists of all birds in all seasons. If ornithologists made the first 100 birds, the process begins to slow down a bit. The number and more diverse species of birds in life, the bird-catcher, not only to move within the state, but remained outside the state.
Life as a detailed list only seen in the pre-printed list. Other data that is displayed on the control place, date, time and circumstances and view notes. Birds added to the life of birds, bird observer positively identified. Poultry are included unstressed fit in the list. Birds from the list of excluded ornamental birds and dead birds were caught, and escaped exotic birds. Observation of birds under ethical conditions, only those that are counted.
Field maps, on the other hand, the status, nature of the birds seen on the website contains information. Status can be determined on a checklist or field card for permanent residents, temporary migrants and breeding. Field maps are very important for beginners who dares step because it helps get a sense of anticipation or excursions.
Birding List majorly two regions, namely the American Birding Association (ABA) list of areas and the world list. ABA represents the regions of Canada, America and other regions adjacent to the water limit of 200 miles. ABA Checklist Committee is responsible for providing ABA bird list. “Birds of the World” book, written by James F. Clements defined dictionary of birds.

The plants are inherent defense mechanism to protect them from predators and pathogens. Disability, largely complementary defensive adjustments to help the plants to survive and reproduce successfully to move. Allelochemicals act as toxins in plants and in some cases reduce the digestibility of plant cell wall.
Some of the external structural properties of stem and leaves (spines, thorns, spines, etc.) in order to prevent insect damage greatly. These mechanical protection to deter, injure or kill herbivores. Some protective substances such as wax, resin, lignin, etc. in the epidermis of plants and herbivores to avoid feeding set.
Herbivores are critical elements in the food chain because they are a source of energy for the highest-ranking authorities in the food chain. Plants are the only source of food for herbivores, the joint development of devices that enable them to buy food, regardless of plant defense mechanisms. Some of these changes are:
Can reduce the synthesis of enzymes, secondary plant compounds
* The existence of internal symbiotic bacteria, fungi, and protozoa to break down the cellulose from plant, so that they can be digested by herbivores helps
* Mechanical modifications to eat incisors months helps the soft leaves.
Among these adaptations is the most important host manipulation mechanism by which herbivores eat plants better. According to recent research by Renato Almeida Sarmento and his team performed, manipulates its host Tetranychus invasive Evans (red) with signaling pathways in defense mechanism [1] involved disturbing.
Primary hosts T. Evans that the potato, such as tomatoes, potatoes, etc., snuff, mites The pins in the leaves, and food, leading to bleaching or yellowing of the leaves. Then the leaves fall and heavy attack, when the plant dies. Sarmento study shows that T. Evans to manipulate the host’s defense mechanism to inhibit the induction of salicylic acid and jasmonic acid signaling pathways in plant protection products in tomato plants involved. Salicylic acid and jasmonic acid plays an important role in plant immunity. Mites reduce the amount of the inducible defense and volatile compounds (eg, protease inhibitors), which plays a crucial role in plant defense. As a result of research by Sarmento, allows a better understanding of plant-herbivore interactions. It opens the door for future research in two directions:
* Biological control of Tetranychus Evans, at an affordable price to the farmer.
* The development of varieties in a position to combat manipulation of herbivores.

One of the last days abroad to contact me, at the beginning of research, especially in the computer interfaces. Professor of neurobiology and finished my business, it showed. Well, well, I agree with what he says, in fact, the future of all these results too.: “This computer / human interface devices in the future is possible”
I realize neural network and an alternative set of brain signals into computer chips in addition to zero and I think to convert. And I know, of course, additional storage devices such as a promotion, physics, mathematics, and chip technology, and human, as Watson ICBM depends on the internet. Applications are varied, not only control cars, airplanes, appliances, wheelchairs, white goods, computers, as well as human interaction, and “Arthur C. Clarke 3001-style” border for the space “,” good.
The future of mind control and “brain break” issue, but now people can be accepted without this technology today, something that seems like enough. Nano-technology and Moore’s law will help to build web sites and materials and a place to read and interpret the available interface, and at the same time, the brain, the blood-brain barrier, nutrients and herbs still submerged biological threats. I know, I have thought all this stuff about, “he said, and I in our dialogue, but a problem and begin to dance around this issue and I do not know where to come up with something brilliant thesis. In the future, a breakthrough scientific work in this place?”
Only one device, the artificial neural networks have developed a Science News, a new member of the California Institute of Technology is an interesting article about how to give an idea of ​​rapid progression, the DNA appeared in Aerospace Daily Article and quality demanded by the document. Space Daily article, “Caltech scientists create DNA for the first artificial neural networks”, Pasadena, CA (SPX) turned out to be the editor titled, and July 27, 2011. Really interested in this topic, you must see this article.
Article says: “This is not artificial intelligence, a robot or a silicon chip, but it is an important step towards creation of in-vitro behavior, may seem too difficult to implement for many years biochemical hypothesis artificial brain.”. But at least to test the concept, there is almost. This is a matter of time.
