...the open hand symbolizes the relaxed discourse of the orator. This theory can be very useful to the modern composition classrooms, and I agree with the rhetorical aspect of writing instead of the process of how one writes; I do not find Corbett’s work useful for me as a teacher. Corbett goes all the way back to the disciplines of rhetoric and logic that were incorporated in the English Renaissance schools. To me, this theory is too structured, and students need to be motivated to write freely and thus begin to enjoy writing. Students who can overcome the fear of writing can then be taught the different forms of writing techniques as well as the grammatical aspects of writing. In contrast to Corbett, Peter Elbow is considered the pioneer of freewriting. Elbow urges teachers to help students express themselves while they write by using multiple drafts and by engaging students, in what he calls, classroom writing, in which students generate ideas by participating in a class discussion and then writing based on the discussion. I strongly believe that we as English teachers must go back to the basics of writing and help the struggling students who know nothing about reading and writing. How can I, as a future teacher, focus on the student’s writing product when they have no clue how to create a complete sentence? I agree with Elbow’s theories of expressivism and his “focus on the individual learner” (78). Although this process sounds more challenging and much more lengthy...

...accuracy of the system depends on the quality of cameras; higher the quality of the cameras the greater the accuracy of details obtained. Markers are placed on the body to create a 3D image of that body. High resolution cameras are used to emit infrared rays that reflect back from the markers and create images on the software. Cameras and software are interlinked through sync box. High speed cameras are required where fast moving objects need to be captured [9]. Figure 2-2 Vicon technology used for animated movies. Another technique that can be used to find angle is discussed by Qaisar et.al. [5]. MicroElectro-Mechanical System (MEMS) based motion sensors are used in this system. The combination of gyroscope and accelerometer provide data about the position and orientation of the object in question. After sensing the required data they communicate with the processing unit where it is then compared with the data set. At the end ICC rules are taken into consideration to finalize the decision [7] [5]. In this paper system design has been divided into three parts which are: • Choice of sensors. • Choice of communication technology. • Processing of data. As mentioned above that the motion sensors used by Qaisar et.al. are gyroscope and accelerometer [5]. Choice of these sensors is mainly due to their small size and low power consumption. The communication device used is Bluetooth because of its advantages. It is feasible for short range communications and operates at a low power...

...Geometry of a Scroll By definition, a volution is a turn or twist about a center. A volute is a spiral. A spiral is a circular curve: the locus of a point moving with an ever increasing radius about a fixed center. A spiral may have one or more volutions, as shown in Figure 1. There are many different kinds of spirals, each defined by variations of a basic mathematical equation. The fundamental spiral form is the Spiral of Archimedes, which is defined by the simple equation: r = a, where r is the radius from a fixed center, a is a constant and is the angle (in polar coordinates). Other variants include the hyperbolic spiral, parabolic spiral, logarithmic spiral and involute spiral. If we add a third dimension to a simple spiral, the result is a coiled plane similar in appearance to arolled strip of paper. Ancient scribes rolled written parchments onto wooden spools for storage and safekeeping, which is where we derive the term scroll. Of particular interest to scroll compressor design is the involute spiral, shown in Figure 2. An involute spiral is a spiral with a continuously variable radius measured from the circumference of a base circle centered on a fixed axis. The curve can be visualized as the end point of a tightly pulled cord unwinding from a cylinder. The shape of an involute permits opposing machine elements to mesh so that the bearing faces roll against one another rather than slide (e.g., gear teeth). This reduces friction and wear, and produces a constant...

...Summary A solar powered pump is a pump running on electricity generated by photo voltaic. Unlike a normal pump, solar power pump being powered by the renewable electricity generated from the sun. Basically, a solar power pump consists of 4 parts which is the actual fluid pump, the controller, the engine which usually powered by electric motor and the energy source being powered by the sun. Dr. Mohd. Azree named this project as solar power pump and being assigned to all group leader of the class. The main objective of this project is to select a solar power pump by identifying whether the existing of pump is really ideal or need to be replaced. Actually, there is already had existing solar power pump build at BH building and in order to achieve our main objective, early research need to be done about the existing solar power pump which lead by Mr.Halil. Besides that, details calculation will be done in order to approve the existing pump suitable or not. Discussion about the project will also be done and some recommendation will be list out if the existing pump is not suitable. Lastly, I hope that this project will achieve the target and will bring benefit to the future research in solar power pump area. Abstract This project serves the purpose of being a validation to the existing solar powered water pumping system installed in Universiti Tenaga Nasional (UNITEN). The solar powered pump is an effort of UNITEN’s collaboration with an agency that are investing in providing...

...[Your Name] [Course Title] [Teacher’s Name] By [Your Name] [Course Title] [Teacher’s Name] By [Report Title] [Report Title] Motivation The applications for 3D Printing in Healthcare are immense. One of the most obvious is its use in printing prosthetics, which face a high rejection rate due to improper fit. Traditional prosthetic hands cost upwards of $50,000, and many insurance companies refuse to pick up the bill for children, who end up outgrowing them within only a couple years. It’s just not practical from a financial standpoint to spend $50,000 for a hand that a child may get very minimal use out of. Using open source 3D printable design files, anyone with a 3D printer can print out a custom sized prosthetic hand in a matter of hours. The price tag? Between $15-$50. That’s right, less than 1/10,000 of the price of traditional prosthesis. There are literally thousands upon thousands of children with severe upper limb disabilities from all over the world. The ability to create extremely affordable prosthetic hands means there is tremendous potential for all of these children and even adults to benefit from this Prosthetics Definition In medicine, a prosthesis, (from Ancient Greek prósthesis, "addition, application, attachment")[1] is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or congenital conditions. Prosthetic amputee rehabilitation is primarily coordinated by a prosthetist and an inter-disciplinary...

...Chapter 1 INTRODUCTION Bionics (also known as biomimetics, biognosis, biomimicry, or bionical creativity engineering) is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. The word "bionic" was coined by Jack E. Steele in 1958, possibly originating from the Greek word "βίον", pronounced "bion", meaning "unit of life" and the suffix -ic, meaning "like" or "in the manner of", hence "like life". Some explain the word as being formed from "biology" + "electronics". We are entering a new era of technology inspired by lifestyle and healthcare. The human body is a significant application area for technology and, under the research theme of bionics, we are applying the techniques and understanding of engineering to applications which will improve human health. Our research group is a multi-disciplinary team of engineers, clinicians and biochemists, interfacing engineering technologies to biological systems to improve chronic disease management. The team is developing biomedical platforms based on established techniques and leveraging on semiconductor technology to produce a new breed of medical devices. Such examples include silicon β-cells in a bionic pancreas for diabetics, ultra low power solid-state bio/chemical sensors for continuous monitoring, advanced microfluidics for lab-on-chip technologies, neural monitoring and stimulation to enable future diagnostic/monitoring tools, in addition...

Pijl Zieber RN, BSN 2002; Revised 2004 INTRODUCTION Welcome to the Back Care and Patient Transferring Techniques workshop. I am confident that your time spent in this workshop will be extremely valuable to you. You have chosen a line of work that is physically demanding. There are also many psychological and emotional demands when working closely with people. As care providers who work with individuals who have limited physical capabilities you are at risk for getting hurt. When you assist individuals who require help walking or transferring (for example, from a bed to a wheelchair) you need to be very careful and use techniques that protect your back. As you will learn in this workshop, the back is vulnerable, but there are methods you can use to minimize the risk of personal injury while transferring and assisting individuals. These techniques are some of the most valuable skills you will learn because they will prepare you for a long, injury-free career and a disability-free life away from work. This workshop will cover topics such as: basic back function, exercises to protect and strengthen your back, body mechanics for lifting and transferring, assessing patient abilities, patient transfer criteria and transfer levels, no-lift policy, and a variety of techniques used to move patients from one place or position to another.

...of PUs has increased in the US between 1995 and 2008. The purpose of this paper is to review the incidence of PUs and how to prevent its occurrence and nurses’ responsibility. Practice Setting Problem Pressure ulcer occurs when part of the skin and the tissues underneath are impaired as a result of being placed under enough pressure to impair blood supply. Immobility-related pressure ulcers are defined as localized areas of tissue damage that develops when soft tissue is compressed between a bony prominence and an external surface for a prolonged time. The most common sites were the sacrum, the heel, the ischium and the trochanter. Pressure is where the weight of the body squeezes the tissues between a bony prominence (such as heel, elbow, sacrum or ischials etc) and a hard surface (such as bed, chair or, in the case of heels, the floor). There are four critical factors contributing to the development of pressure ulcers: pressure; shearing forces; friction and moisture. Beside these factors there are also patient factors such as neurological, impaired mobility, poor nutrition and poor posture or deformity that can contribute to the development of PU (Cooper, Vellodi, Stansby, & Avital, 2015). Importance of the Clinical Problem and its...

The limitations on packing makes it suitable only for very low temperature and low pressure services. Fig 2.1 indicates the general arrangement of a slip type expansion joint. [pic] Fig 2.1 2.2 Bellow Type Expansion Joint The bellow type expansion joint is extensively used as the most efficient and functionally reliable elongation compensator and/ or vibration isolator. These are capable of compensating for large amounts of axial and/ or lateral and/ or angular movements as a single unit. It lends itself to piping configurations that are much more compact than those using bends or loops to provide flexibility. 3. USAGE AND RESTRICTIONS Based on the above, the point of usage could be identified as below. • At the suction and discharge nozzles of vibrating equipments such as pumps, blowers etc., • On large...

...The Skeletal System Overview Can you imagine what the human body would be like if it were devoid of bones or some other form of supporting framework? Picture a "blob" utilizing amoeboid movement. Ugh! The skeletal system consists of bones and related connective tissues, which include cartilage, tendons, and ligaments. Bone is a living tissue and is functionally dynamic. It provides a supportive framework for vital body organs, serves as areas for muscle attachment, articulates at joints for stability and movement, and assists in respiratory movements. In addition, it provides areas of storage for substances such as calcium and lipids, and blood cell formation occurs within the cavities containing bone marrow. The skeletal system consists of 206 bones, 80 of which are found in the axial division, and 126 of which make up the appendicular division. Many of the bones of the body, especially those of the appendicular skeleton, provide a system of levers used in movement, and are utilized in numerous ways to control the environment that surrounds you every second of your life. Few people relate the importance of movement as one of the factors necessary for maintaining life, but the body doesn't survive very long without the ability to produce movements. The study and review for this chapter includes microscopic and macroscopic features of bone, bone development and growth, location and identification of bones, joint classification, and the structure of representa tive...
