Boas - Boidae - Constricting Snakes

Boas (Boidae) are a group of nonvenomous snakes that include about 36 species. Boas are found in North America, South America, Africa, Madagascar, Europe and many Pacific Islands. Boas include the largest of all living snakes, the green anaconda. Other Snakes Called Boas The name boa is also used for two groups of snakes that do not belong to the Boidae family, the split-jawed boas (Bolyeriidae) and the dwarf boas (Tropidophiidae). The split-jawed boas and the dwarf boas are not closely related to members of the family Boidae. Anatomy of Boas Boas are considered to be somewhat primitive snakes. They have a rigid lower jaw and vestigial pelvic bones, with small remnant hind limbs that form a pair of spurs on either side of the body. Although boas share many characteristics with their relatives the pythons, they differ in that they lack postfrontal bones and premaxillary teeth and they give birth to live young. Some but not all species of boas have labial pits, sensory organs that enable the snakes to sense infrared thermal radiation, an ability which is  useful in the location and capture of prey but which also provides functionality in thermoregulation and detection of predators. Boa Diet and Habitat Boas are predominantly terrestrial snakes that forage in low lying bushes and trees and feed on small vertebrates. Some boas are tree-dwelling species that stalk their prey by hanging their head down from their perch amongst the branches. Boas capture their prey by first grasping it and then coiling their body quickly around it. Prey is then killed when the boa constricts its body tightly so that the prey cannot inhale and dies of asphyxiation. The diet of boas varies from species to species but generally includes mammals, birds and other reptiles. The largest of all boas, in fact, the largest of all snakes, is the green anaconda. Green anacondas can grow to lengths of over 22 feet. Green anacondas are also the heaviest known species of snake and may also be the heaviest squamate species as well. Boas inhabit North America, South America, Africa, Madagascar, Europe and many Pacific Islands. Boas are often regarded solely as tropical rainforest species, but although many species are found in rainforests this is not true for all boas. Some species live in arid regions such as the deserts of Australia. The vast majority of boas are terrestrial or arboreal but one species, the green anaconda is an aquatic snake. Green anacondas are native to the slow-moving streams, swamps, and marshes on the eastern slopes of the Andes Mountains. They also occur on the island of Trinidad in the Caribbean. Green anacondas feed on larger prey than most other boas. Their diet includes wild pigs, deer, birds, turtles, capybara, caimans, and even jaguars. Boa Reproduction Boas undergo sexual reproduction and with the exception of two species in the genus Xenophidion, all bear live young. Females that bear live young do so by retaining their eggs within their body give birth to multiple young at once. Classification of Boas The Taxonomic Classification of boas is as follows: Animals Chordates Reptiles Squamates Snakes Boas Boas are divided into two subgroups which include the true boas (Boinae) and the tree boas (Corallus). True boas include the largest species of boas such as the common boa and the anaconda. Tree boas are tree-dwelling snakes with slender bodies and long prehensile tails. Their bodies are somewhat flat in shape, a structure that gives them support and enables them to stretch from one branch to another. Tree boas often rest coiled up in the branches of trees. When they hunt, tree boas hang their head down from the branches and coil their neck in an S-shape to give themselves a good angle from which to strike their prey below.

Essay on Animal Farm by George Orwell - 1117 Words

Orwell deals with the problem of rhetoric in ’Animal Farm’ by demonstrating how language can cause corruption. There are many characters in his book ‘Animal Farm’ that use rhetoric to convince and manipulate, however, the most talented persuasive speaker is Squealer. Squealer’s ability to use rhetoric is unrivalled, this is the reason Napoleon rises to power. Squealer uses the power in language to distort the truth in his speeches. When Napoleon wanted a problem fixed he would simply ask Squealer to talk to the animals and the animals would believe and be on board with whatever he said. Squealer uses many persuasive techniques such as rhetorical questions, inclusive language and exaggeration, but most of all he uses rhetoric. Rhetoric,†¦show more content†¦He had no persuasive power but he had fear. Later in the book to justify what he did to Snowball he employed Squealer to make Snowball look like a bad guy which in doing so inferred that N apoleon was the good guy. Once again Squealer uses the power of language to distort the truth and use persuasive rhetorical questions that the animals can only agree with.† Surely, comrades, you do not want Jones back?†, he persuaded the animals to believe that Snowball was plotting to get Mr. Jones back in control by double crossing them at the battle of the cowshed. He made the animals believe that Snowball was evil from the start and even though at first the animals did not believe it, they quickly disregarded their shared thoughts just because they were told to do so by a pig. Benjamin, the donkey sees straight through this but never bothers to tell anyone. When an animal said that Snowball did in fact fight well in the battle of the cowshed Squealer was quick to say that it had all been staged and they all believed it. This demonstrates the gullibility of the animals. The animals are easy targets for Squealer and the pigs as they are uneducated, ignorant and gullible. They are easily convinced and controlled. It only takes a couple of swift words from Squealer and you will have almost all the animals on board and agreeing with him.

13th USENIX Conference on Hot Topics in Operating Systems

Question: Describe about the 13th USENIX Conference on Hot Topics in Operating Systems? Answer: In the question there is a link provided of an article. and the article consist the information about the 5 ways the windows beats the iOS. But after reading the article iam disagree with the article. The two points due to which iam disagree with the article are as follows-: Navigating the Windows 8 touch interface involves a steep learning curve. The first point on which iam disagree is that one side in the article it is mentioned that now a days more peoples are using the windows 8 operating system. as this operating system is inbuilt in the tablets, it is so much in demand, but on the other side same in the article it is mentioning that the use of windows 8 is not easy than the ios. So iam disagree with the point mentioned on the above. iOS doesnt let you create fully accessible, eminently manageable files. The second point on which iam disagree is that ios doesnot help us in creating completely accessible files and properly management of those files. As we all know that the ios operating system is used in Apple. And the ios system properly creates and manages the file system. so according to me iam not agree with the above mentioned sentence that I extract from the link provided of the article. Two areas that will not cause problem to the organization server are as follows-: Unix Security model may be too primitive. As the article shows that the security model of the unix is totally based on the ACL concepts means Access Control Lists. Instead of providing the facility of user ID and Password to all user it is centrally administered. Unless it is primitive but it increases the security of the system. and now a days the new innovation takes place in the security model of the unix that all the user within the organization are authenticated by a valid user ID and Password and owner of particular system decides who can view and access the file. so there is no problem to use unix in the organization web server as it doesnot cause any problem related to security matters. Unix Supports for GUI is Weak. As in the article it is mentioned that the GUI support of unix system is weak. It doesnt mean that the unix system doesnot prvide graphical effect to the system. unix system follow the long route to access any feature within the sytem. But it doesnot create problem for organization server. As we all know that GUI (Graphical User Interface) helps in understanding the system features easily and provide flexibility while using the system by user.3) As in the question it is mentioned to develop the operating system for the organization in order to run the application related to stock market for buying and selling of stock. And it is asked in the question about the best scheduling activities for the operating system that helps the system in order to process more than one process at a time received from different sources. So, In order to develop the multitasking operating system for the new application real time scheduling activity will be best. Because multitasking is a method where at a time various tasks arrive at the system for processing. In this one task dont wait for other in order to start processing until the first process completed. According to the application which operates on multitasking operating system, real time scheduling will be best. Because as in the question it is mentioned that the buying and selling of shares application works on the operating system which needs the fast processing towards the system without waiting a lot or in other words we can say that without waiting for their turn.Real time processing methods deal with input request very fastly without further delay. As the input request came in the system fast processing takes place within the system and immediately the output generates from the system. this is the basic concepts of real time processing. The reason to use the real time scheduling in multitasking operating system are as follows-: 1) Increased Performance rate-: Real time system helps in increasing the performance rate of the system as it process more processes within the short period. In this way, it helps in increasing the performance rate of the system. 2) Fast processing without delay-: Real time system performs processing of the process very fast without waiting for their turn. So it helps in stopping delay within the system while processing the data. References Bailey, K., Ceze, L., Gribble, S. D., Levy, H. M. (2011, May).
