Explain the benefit of designing a foundation with LRFD as opposed to ASD Solution The LRFD is certainly an improvement over the ASD. It takes better account of variability in both loading and resistance. LRFD is a reliability based design. Even before taking my reliability based design class, I always had my doubt in applying a single factor of safety for an output derived from inputs of varying reliability. The one disadvantage of LRFD is the lack of sufficient statistical data to select appropriate factors in certain specific cases, but still better than ASD..

describe the three major categorical theories of language development,as listed below .consider the emphasis each places on innate abilities versus environment influences.also attribute key terms and theorist with one if the following categories. write a one page report on a language theorist or researcher who asserts a position that is different from your own preferred notion. .Behaviorist .Nativist .Interactionist Solution 1). Behaviourist: This is proposed by the behavioural theorists Skinner. As per his theory, children imitate what they see and hear and all behaviour is acquired by learning, so it can be unlearned by either the positive reinforcement or negative reinforcement. Skinner proposed that the speech of children is shaped by adults by reinforcing the babbling of infants. 2). Nativist: Nativist Noam Chomsky proposed a “LAD”, Language Acquisition Device, and believed that children are born with certain innate skills of language learning, which determines their speed of learning. They can learn the native language at a high speed and can improve their grammatical skills without much effort. The same inheritance factor is responsible for the skill of learning multiple languages in certain people. 3). Interactionist: Lev Vygotsky described the concept of “zone of proximal development,” which explains how the children learn better from the other children, i.e. collaborative learning. School environment play an important role in improving the intellectual skills of the children by means of classroom teachings and also learning from the other children. Interaction with the other school children also influences the development of communication skills in the society. Children learn from the other children in a better way than do from the adults..

case study of a female with a parasitic disease Here is a Microbiology student\'s story from her point of view and in her own words. Some words were changed to aid in understanding, but the context was not changed. This is an actual illness that happened to me whenIwas 18 years old lving in Freetown, Sierra Leone, on the west coast of Africa. Here is some background information tounderstand our living situation: My family and moved to the city as displaced refugees due to several rebel attacks in my home town during the war. We rented afour bedroom apartment for a family of over fifteen and shared two pot- hole toilets with over seventy people. The house llved in was on top of asteep hilandat the bottom of the hill was a runni down the hill, but ng stream of water where people in the neighborhood did laundry,inever went there were many monitor lizards by the stream that would come up the hill sunny days to bask on the rocks. My family and lused to dry our clothes on the rocks after washing them. My cook helped with the laundry and a few times, my older sister bought snail meat from the market to because it was cheap and I helped her prepare the food. on the last day of school holiday, had a sight headache way home. When got home my mum gave me Tylenol (500mg) and I went to bed, but headache did not stop That evening had a slight fever and some body aches. The headache continued and was constant, with high fevers in the evenings and nights, and accompanied by chills. I have a brother who is a doctor and was working in a private hospital. After a week of constant headaches, and fevers my brother didamala test which was positive. I was gven since symptoms got worse even after reatment for malaria, I was vomiting a lot, anemic, had abdominal pain. received a blood transtusion with was very weak, could not walk and was dizzy all the time. One day, was unconscious for a couple of hours and my family thought Iwas dying. This was after my My to a stool found out another parastic disease along with malaria. I was given Braziguantel for a day and after a days was feeling better and back my feet.ido not remember the exact three months, submitted another stool sample for testing and it was negative.I was free from the second parasite. Below is a picture of the eggs that the doctor would have seen upon microscopic examination of the patient\'s stool. Distribution of this parasite is throughout Africa, but can also be foundins America, the Caribbean, and Puerto Rico. what are the possible diagnoses for this patient? What are your clues?

What are concrete components? 26. What are footings? Name two types and show how they relate to the building? 27. What are two types of Concrete Buildings Systems? 28. What are the six categories of concrete wall systems in current use? Solution 18) Bleeding in fresh concrete refers to the process where free water in the mix is pushed upward to the surface due to the settlement of heavier solid particles such as cement and water. Some bleeding is normal but excessive bleeding can be problematic. The way you work that bleed water can affect the durability of your products. The biggest factor in bleed water rates is the water-to-cement ratio. A higher ratio can lead to excessive bleeding. The cement type and fine aggregates can play a role in determining the bleed rate. The fewer fines you have in your mix, the more bleeding will occur. Factors also include concrete height and pressure. The relationship between bleed water and concrete heights starts off as linear, but eventually becomes nonlinear at increased heights. Ways to reduce bleeding in concrete include: 19) Portland cement is a basic cement mixture and a fundamental ingredient for many common cement applications. Because Portland cement is very common, it is also often called “Ordinary Portland Cement” or simply “OPC.” Since the early 20th century, Portland cement has been used internationally for a wide variety of applications including concrete projects, mortar pastes, stucco decorations, and grout fillings Roman cement was the predecessor to ordinary Portland cement. A crude form of Roman cement was rediscovered by English engineer John Smeaton in 1756. The formula for Roman cement was refined and patented in 1796 by James Parker. Around 1811, James Frost developed British cement: a new way of processing cement that became instrumental in making Portland cement. In 1824, the first form of Portland cement was patented by English cement manufacturer Joseph Aspdin. Aspdin’s version of Portland cement was further refined by his son, William, in 1843, and it closely resembled the ordinary Portland cement we know today. The United States imported Portland cement from Germany and England as early as 1868. Between the 1970s and 1980s, the United States began manufacturing their Portland cement in Michigan and Pennsylvania. Within a few years, most of the Portland cement used in the United States was produced locally. 20) For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals o.

Which members of the truss are zero-force members? Solution assuming all members to be weightless. at the joint E, the only force possible in the vertical direction is due to DE. so the vertical component of force in DE should be zero, because the joint E is at equilibrium. If the vertical component is zero means there is no force in that member; it is a pin jointed member and force will be along the bar and it is an inclined bar. if there is a horizontal component, there will be a vertical component. EF is a zero force member, because there is no force in x direction at E as discussed before. at joint D sum of forces along x direction should be zero. Since the DE is a zero force member, CD should also be a zero force member DF should also be a zero force member because at D both others are zero force members and there will be no member to offer reaction force. CF will have some force since it will have to compensate the vertical 10KN. and all other members will havesome force from there onwards. the values of force will depend on the lengths of the members. so the zero force members are CD, DE, DF, and FE.

Which THREE of the following statements about autotrophs and heterotrophs on Earth are TRUE? Question 10 options: The answer is NOT 2, 6, 7 or 3, 5, 4 Heterotrophs that do not eat autotrophs every day will die in a short time. Autotrophs depend on heterotrophs to oxidize sugar and release CO2 into the atmosphere. The majority of heterotrophs on Earth do not use aerobic respiration as a form of energy conversion. Heterotrophs evolved on Earth before autotrophs. The majority of autotrophs on Earth require aerobic respiration in order to survive. Heterotrophs are dependent on autotrophs to generate O2 from H2O in order to support aerobic respiration. Heterotrophs depend on autotrophs for conversion of light energy to chemical energy. There are no metabolic differences between autotrophs and heterotrophs. Heterotrophs that do not eat autotrophs every day will die in a short time. Autotrophs depend on heterotrophs to oxidize sugar and release CO2 into the atmosphere. The majority of heterotrophs on Earth do not use aerobic respiration as a form of energy conversion. Heterotrophs evolved on Earth before autotrophs. The majority of autotrophs on Earth require aerobic respiration in order to survive. Heterotrophs are dependent on autotrophs to generate O2 from H2O in order to support aerobic respiration. Heterotrophs depend on autotrophs for conversion of light energy to chemical energy. There are no metabolic differences between autotrophs and heterotrophs. Solution the correct statement would be : 4: because autotrophy is more complex than heterotrophy , the very first organisms were heterotrophs because they could feed on the molecules surrounding them. 6: Heterotrophs are dependent on autotrophs to generate O2 from H2O in order to support aerobic respiration. because if the autotrophs do not produce oxygen then heterotrophs can\'t live. infact the earth\'s atmosphere before autotrophs was without oxygen 7: Heterotrophs depend on autotrophs for conversion of light energy to chemical energy. similarly, heterotrophs never had the ability to convert sunlight into chemical energy. they only depended on autotrophs to produce food when the moleclar food was scarce..

What makes it hard for radiation to transfer heat to the center of the potato? d. Why does inserting a metal skewer through the potato help it to cook quickly e. Why Can a Microwave do this job more efficiently and quicker? f. What is a potato clock and why does it work? 2. An electric hot water heater takes cold water at its inlet pipe and delivers hot water at its outlet pipe. Between these two pipes is a large water container. Many electric hot water heaters have two separate heating elements: one near the top of the water container and one near the bottom. Both heating elements project into the same hot water container inside the water heater. When the top element is heating water at the top of the container, why doesn’t convection occur and cause water at the bottom of the container to also become hot? Convection dictates where the water pipes attach to the container. Where hot water should be extracted from the container, and where should cold water be introduced into the container to replace that hot water? Why does the water heater’s bottom heating element operate more often and age more quickly than its top heating element? Why is it important to thermally insulate the hot water heater’s container? Energy flows into the hot water heater as electricity. Since energy is conserved and can’t accumulate forever inside the heater, it must leave somehow. At a time when the hot water is being used, how does most of the energy leave the hot water heater? How does “Instant Hot” water in a water cooler work differently? g. After a new water heater is installed in the basement, the bathroom sink in a 2 story home keeps banging and shooting out water.
