What does the choriod do?
The choroid, also known as thechoroideaorchoroid coat, is thevascular layer of the eye, containingconnective tissue, and lying between theretina and thesclera.The choroid providesoxygen and nourishment to the outer layers of theretina. Along with theciliary body andiris, the choroid forms theuveal tract.
What is thefunctionof a frog brain?
The frog brain is responsible for processing sensory information, coordinating motor functions, and regulating basic life processes. It plays a crucial role in behaviors such as hunting, mating, and navigating their environment. The brain also helps in the integration of signals from the frog's senses, enabling it to respond effectively to stimuli. Overall, it is essential for the frog's survival and interaction with its surroundings.
What tissue occupies the center of the dicot stem?
cortex- In dicot stems, the cortex is located in the area between thevascular bundles and the epidermis. In monocot stems, it occupies the area surrounding the vascularbundles. The center of the stem is pith and may function as storage.
How does scar tissue form in burns?
Scar tissue is formed when the depth of injury penetrates the dermis.Scar tissue occurs in 4 phases:1.Inflammatory phase.In this phase,blood clot forms around the edges of the injury.Blood vessels dilate, macrophages migrate to the site of injury to clean up dead cells or other unwanted organism.the macrophages activate fibroblast response.2.Migratory phaseIn this phase, scab ,a hard coating on the skin formed during the wound healing,is formed.Epithelial tissue migrate beneath the scab to bridge the wound.Fibroblasts proliferate in the deeper part of the woundThese fibroblasts begin to synthesize small amounts of collagen which acts as a scaffold for migration and further fibroblast proliferation.Blood vessels begin to grow.Granulation tissue refers all the tissue involved in filling the wound.3.The proliferative phase-Growth of the epithelial tissue closing the wound-continued growth of blood vessels.-Collagen fibers are laid randomly4.Maturation phase-The scab sloughs off from the epidermis-collagen fibers become more organized-fibroblasts decrease in number-blood vessels restored to normal
Who lost the Vietnam War?
Why South Vietnam fall to North Vietnam is still very controversial. The popular Western answer is the U.S. stopped fighting and South Vietnam didn't have the resolve to fight against the Viet Cong and NVA, and were quickly defeated. However, that is far from the truth.ARVN (South Vietnam's army) were fighting against the Viet Cong before and after U.S. military involvement. Nixon gets credit for Vietnamization of the Vietnam War, but ARVN was actually taking over the fighting while Johnson was still in office. ARVN controlled 95% of South Vietnam by the time the Paris Peace Accords was signed in 1973, and retained control until U.S. support was cut by congress after Nixon resigned from office.The Soviet Union and China ramped up their support to North Vietnam while congress cut support to South Vietnam. This quickly caused North Vietnam to become the superior military force while ARVN and South Vietnam became disillusioned of their future. ARVN was no match to the NVA when the Ho Chi Minh Campaign started, and they were quickly routed.Henry Kissinger's recently released private notes suggest another reason why South Vietnam lost. After Soviet-Chinese relations broke down in the early 70's, a deal between China and the U.S. suggests that U.S. interests in Southeast Asia would be given uo for this great shift of power in the Cold War. Nixon's Vietnamization of the War was merely a front to cover South Vietnam being sacrificed.
What are the software engineering project's phases?
A process model for software engineering is chosen based on the nature of the project and application the methods and tools to be used and the controls and deliverables that are required.All software development can be characterized as a problem solving loop in which four distinct stage are encountered, these are status quo, problem definition, technical development, and solution integration, status quo represents the current state of affairs, problem definition identifies the specific problem to be solved, technical development solves the problem through the application of some technology, and solution integration delivers the result to those who requested the solution in the first place.Technical developmentStatus quoSolution integrationProblem definitionFigure: The phases of a problem solving loopThere are several models used in S.E these are –i. The linear sequential model.ii. The prototype model.iii. The RAD model.iv. The increment model.v. The spiral model.vi. The win win spiral modelvii. The concurrent development modelviii. The component based development model#The linear sequential model/waterfall model-The LSM sometime called the classic lifecycle or the waterfall model. This model suggests a systematic sequential approach to software development that designs at the system level and progress through analysis, design, coding, testing and support. The LSM encompasses the following activities-System /information engineering and modeling .Because software is always part of a larger system the work begins by establishing requirements for all system elements and then allocating some subset of these requirements to software. This system view is essential when software must interact with other elements such as hardware, people and database. System engineering and the analysis encompass requirements gathering at the system level with a small amount of top level design and analysis. Information engineering encompasses requirements gathering at the strategic business level and the business area level.i.Software requirements analysis-The requirements gathering process is intensified and focused specially on software. To understand the nature of the problem to be built, the software engineering must understood the information domain for the software as well as required function. Behavior, performance and interface requirements for both the system and the software are documented and received with the customer.ii.Design-Software design is actually a multistep process that focuses on four distinct attributes of a program. Data structures, software architecture, interface representation and procedural detail the design process translates requirements into a design which documented and becomes part of the software configuration.iii.Code generation-The design must be translated into a machine readable form. The code generation steps perform this task. If design is performed in a detailed manner code generation can be accomplished automatically.iv.Testing-Once code has been generated, program begins. The testing process focuses on the logical internals of the software, ensuring that all function externals that is conducting tests to uncover errors and ensure that defined input will produce actual result that agree with required results.v. Support-System/information engineeringAnalysisDesignCodeTestSoftware will undoubtedly undergo change often it is delivered to the customer change will occur because errors have been encountered because the software must be adapted to accommodate change in its external environment or because the customer requires functional or performance enhancements. Software support maintenance reapplied each of the proceeding phases to an existing program rather than a new one.
What are the Psychological Phases a serial killer goes through?
Long before a serial killer kills for the first time, he has been satisfied with violent fantasies. When those fantasies can no longer satisfy him he needs to find a victim and kill for real. After the kill he will have a period of relative calm. At this point he may relive the kill with any trophies have may have taken from the victim. But as time goes on the need to kill begins to build again and the hunt starts again. This process will continue until he is incarcerated, whether in prison or mental hospital, he dies or he loses the need to kill as he ages.More information.Psychologist Joel Norris in wrote the Psychological Phases in 1988. There are hundreds of papers in the internet describing this:1. Aura PhaseThe to-be-killer begins with an aura phase, in which there is a withdrawal from reality and a heightening of the senses. It means that the killer distances him/herself from social interactions. Nevertheless, friends, family and those who encounter this person, may not be able to detect this person's change in personality. The killer becomes antisocial and life no longer has meaning to him. This phase may last anywhere from several moments to several months and can begin as a prolonged fantasy, which may have been active for a short time or for years. These fantasies often include sadistic sexual and other violent acts which possibly derive from early childhood experiences. The killer may attempt to medicate himself with alcohol or drugs which often lead to an intensification of the fantasies. After a while they have the urge to be acted upon.2. Trolling PhaseThis leads into the second stage, which is the called the trolling phase. In this phase, the killer tries to find a victim. Most serial killers will search for a victim in places he is familiar with or where he feels comfortable (the so-called comfort zone may be around the killer's neighborhood, in a certain district or area). They will also look for a particular discreet location to perform the murder and to a perfect place to dump the bodies. They usually tend to look in school yards or lovers lanes or even red light districts. This might go on for hours days and sometimes even months, until the perfect victim will be found. In the trolling phase the serial killer often follows a behavior pattern used to identify and stalk his victim. Norris described how Ted Bundy strapped his arm in a sling and asked for help with books, packages, or even the hull of a sailboat to lure the victim into his car. Some victims escaped and said he never seemed out of control until the moment he actually attacked them.3. Wooing PhaseIn the wooing phase the killer tries to win the confidence of a victim before luring it into a trap. This phase is only done by the organized killers who are much more confident, more daring, and has better social skills than disorganized killers. The killer tries to socialize with the victim and - as stated before - tries to gain his victim's trust. This is a very important phase because the organized killer often seems to only proceed to kill those who allow him to gain their trust. "When homicide detectives finally begin to uncover a pattern of serial murder, one of the first things they notice is that the victims rarely seem to have struggle against their killers" (Norris 29). Once the trust is received, the killer will then lure the victim into quiet and secluded area where the killer uncover his/her mask and moved on to the next phase.4. Capture PhaseThe fourth phase is the capture phase. This is where the killer reveals what he is. The capture of the victim can be as swiftly as snapping a handcuff on the victim's wrists, or a blow that renders the victim helpless. The killer may draw his victim into his car which has no door handle one could use as an escape. He usually savors this moment. It is disturbingly fun for him and is included in his sadistic needs. The victim may be taken to a new location, far out from people and help. Once the killer is sure that there's no way for the victim to escape, he move to the climax phase of the cycle, the murder.5. Murder PhaseNorris described the murder phase as the ritual reenactment of the disastrous experiences of the killer's childhood, but this time he reverses the roles. The killer may decides to kill his victim instantaneously, but sometimes he will torture his victim to death, tries to revive it on the brink of death and continue with the torture (Scott). A disorganized killer is more likely to kill the victim instantaneously by a powerful attack or a quick strangulation. It is likely that the corpse is heavily "depersonalized" by mutilations of face and body (Vronsky). Any violent acts such as rape are often taken place after the victim is dead (necrophilia). The organized killer commits a much slower and more painful murder act. The victim is most likely to be tortured and raped before death. In his case the act of killing is delayed because the murder itself it often not the motive of the crime; rather, it is the torturing that the killer enjoys most. This is especially true in the sadistic killers, the most organized of all killers. This type of killers will keep their victims alive as long as possible - sometimes revive them from injuries, keeping them just alive enough to feel the pain from the tortures. The sexual sadistic killers will resources to different equipment's, such as electrical wire that they brought with them to the crime site. "The most prevalent forms of sexual acts inflicted on the victim, in order of case frequency, are anal rape, forced fellatio, vaginal rape, and foreign object penetration" (Vronsky 314). Eventually, when the killer finished with the tortures, he proceeds to kill.6. Totem PhaseThe next phase Norris described is the totem phase. After the kill, the excitement of the killer suddenly drops and he wakes up from his fantasy. He is likely to sink into a depression, which is why some serial killers develop a ritual to preserve their fantasy. They may collect their victim's possessions such as clothes and save news clippings about their crimes. Some serial killer cut off their victim's body parts to preserve and/or consume them. Others take pictures or videotape the crime. The trophy is meant to give the murderer the same feelings of power he experienced at the time of the kill and to remind him/her that the fantasy is real, and he/she really did fulfill it.7. Depression PhaseThe last phase before the serial killer starts over again is phase seven, the depression phase. There is a great emotional letdown for the killer. The depression phase can last for days, weeks, or even months. They may even become so depressed as to attempt suicide. A victim, now killed, no longer represents what the killer thought he or she represented, and the memory of the individual that tortured the murderer in the past is still there. Ressler compares the murder to a television serial with no satisfactory ending because the serial killer experiences the tension of a fantasy incompletely fulfilled. In each subsequent murder, he attempts to make the scene of the crime equal to the fantasy. Norris notes that there is an absence of the killer's sense of self and, during this phase, the killer may confess to the police before the fantasies start once more. However, because victims are not seen as people, recollections of murders may be vague or viewed as the killer having watched someone else. Eventually, the killers will fall back into their fantasies and proceed to the murder again. Each time after the murder, the fantasy will become more real and the murder will become more brutal, the cycle continues on and on until the pattern gets interrupted. The killer's interruption included getting caught, or simply the killer is "burnt out." When the killer is "burnt out," he/she withdraws from killing, and possibly commits suicide. This is one of the reason there are many unsolved serial murder cases. However, the chances are that the killers will not stop killing on his/her own. Serial killing is an addiction, and the killing patterns will be continued.
What are the advantages of three phase to single phase electric power distribution systems?
This Answer is the same as the for the Question 'Why is power for a country's mains grid usually generated as 3-phase electricity not single phase?'Single phase power has a sine wave voltage that crosses zero before reversing its polarity. In the region near the zero-crossing there is not much power. At zero there is none at all. So single phase loads often need some trickery to deliver output in this area. Often it is just the inertia of the motor or appliance.Three phase power is always delivering power on one of its phases, and is thus preferred for machines, motors and appliances that use lots of power.Three phase power generation is preferred if the application needs very high power, or nees relatively small power output but with with weight restrictions - as in automobiles, where the power is generated in a 3-phase alternator and then converted to DC using rectifiers!Use of DC (Direct Current) is the next step up for smooth high-power devices but requires rectification, regulation and smoothing to be useful.Another problem with DC is that, for efficient long distance transmission, it cannot be simply converted to much higher voltages than the voltage at which it was generated at the power station.Similarly DC cannot - simply by using transformers - be converted down to safer, much lower AC mains voltages for use by consumers.Conversion of DC to AC requires the use of expensive high-power electronic "power inverter" systems and the opposite - the conversion of high-power AC to DC - requires the use of very big power rectifiers.AC (Alternating Current) is used for high power generation and distribution because it can easily be transformed, using transformers, to achieve very efficient power transmission over very long distances and can then be transformed down to low voltages for distribution to consumers.Two phase, and higher multi-phases are also used, but very rarely, for a few very specialised applications.A three phase system provides constant torque, whereas single phase does not.With three phase you will get more power per kilogram of metal to generate electrical energy.AnswerFor a given load, a three-phase supply uses less copper than a single-phase system. In other words, it's more economical!
