The Effect Of Soft Tissue Constituent Materials - 1422 Words

The goal of this thesis is to identify the effect of soft tissue constituent materials in tissue classification for the application of breast cancer detection. Hyperelastic parameters may be essential in estimating large deformation in tissue for the purpose of surgical procedures such as breast brachytherapy. These properties of human soft tissue play a significant role in diagnosis, screening, and monitoring of cancer (O’Hagan Samani, 2009). On the other hand, elastography is based mainly on the concept of tissue reactions (linear and nonlinear) to an external source of load such as compression. Moreover, in most breast examination methods, compression is applied to help detect lesions. In CBE and BSE, the examiner applies a compressive load to the breast to investigate stiff regions and must sometimes exert a large deformation to feel lesions in depth. Mammography also uses compression to reduce breast thickness. Additionally, compressive behavior of human breast biopsies obtained through lumpectomy (the surgical procedure to remove a cancer or non-cancer breast lump with some surrounding tissues) is of interest to the cancer research agencies in order to distinguish the mechanical nature of anomalies of the taken biopsy. Despite of the importance of compressive loading and its contribution to hyperelastic characterization of tissue in 9 applications of cancer detection, few studies have focused on the behavior of tissue components in response to compression. The mainShow MoreRelatedThe Mechanical Characteristics Of Soft Tissue2254 Words   |  10 Pagescharacteristics of soft tissue are the basis for several clinical and nonclinical research studies, such as brain surgical simulation or breast needle biopsy (Kaster et al., 2011; O’Hagan Samani, 2009). Usually, anomalies found within the breast are investigated by palpation techniques, in which responses of soft tissue to large deformation are utilized (Goodson, 1996).

Work Redesign Eight Obstacles and Opportunities

WORK REDESIGN: EIGHT OBSTACLES AND OPPORTUNITIES M I C H A E L A . C A M P I O N , T R O Y V. M U M F O R D , F R E D E R I C K P. M O R G E S O N , A N D JENNIFER D. NAHRGANG Successful work-design initiatives must overcome many obstacles in order to have their intended impact. This article outlines eight obstacles to work redesign: (1) influences on multiple outcomes, (2) trade-offs between different approaches, (3) difficulty in choosing appropriate units of analysis, (4) difficulty in predicting the nature of the job, (5) complications from individual differences, (6) job enlargement occurring without job enrichment, (7) creating new jobs as part of growth or downsizing, and (8) differences between longterm and short-term effects.†¦show more content†¦Several challenges, or obstacles, remain, however, for practitioners attempting to implement work-design changes. These challenges emerge for diverse reasons, such as conflicting constituent needs, the complexity of organizations, and the practical realities of the workplace. For example, work designed according to mechanistically oriented principles will be radically different from work designed according to motivationally oriented principles. The seemingly irreconcilable trade-offs between the two approaches represent an obstacle to research and practice because they suggest a dichotomy: work can be either efficient or satisfying. The purpose of this article is to improve understanding of these eight obstacles and to provide direction for managing them. As these obstacles are formidable and defy simple solutions, it is not our intention to completely solve each of them. Rather, we hope to clarify sufficiently the issues involved and to aid practitioners in making informed and rational work-design decisions that complement their particular situation. Obstacle #1: Work Design Influences Multiple Outcomes The first obstacle lies in recognizing that work design influences multiple outcomes.

Favorite Trip Free Essays

Topic #12 I have visited many places in my lifetime, from as far east as Florida to the topics of Kauai. There were two places during my travels that have stuck out to me the most though. Visiting Mason City, Illinois, a little town of twenty-two hundred people and visiting family in Beverly Hills, California, there are bound to be some differences but also, some similarities on the subject. We will write a custom essay sample on Favorite Trip or any similar topic only for you Order Now The majority of people in the United States, even internationally, know what Beverly Hills is. It is the place to be for amazing shopping, fancy cars, big houses, and the place to go to see celebrities. This little town in Southern California is very materialistic. When visiting, I almost felt as though I had to dress and act like these people just to fit into their society. Now, Mason City is my kind of vacation. Back in the country, life really does move slower and it is much simpler. What you wear and what you look like do not matter. The older and more broke down your truck is, the better off you are for mud bogging and road tripping to surrounding towns and the creeks. Everybody knows everybody and where each other live. In Beverly Hills, there are a wide variety of job professions. You could be virtually anything your heart desired, from being a banker to being a personal assistant to someone famous. The work that they do in California is on the opposite end of the spectrum compared to the work they do in Illinois. In Mason City, you either works on some kind of a farm, be it a pig farm or a corn farm, or you work for the local HULL Trucking Company. Obviously, there are other professions there otherwise there would be no local businesses or education, etc. That is virtually impossible. The job choices in both places are ways that people make their livings and contribute to our society. Beverly Hills is an urban jungle, full of high rises and the lovely smell of a big city. There are loud noises and a lot of vehicle and foot traffic through its winding streets and hills. I’m pretty sure that the drivers of these fancy vehicles on these winding streets make up their own rules of the road, almost like they are more obligated than others. In M. C. there is one road in and out of the town, Highway 65. There are not even any traffic lights, and only a few stop signs. Most roads there only require you to yield and make sure there is no one coming. People that are from Central and Southern Illinois say that Chicago and its surrounding suburbs should be considered an entirely different state. I believe that this is true. Central Illinois is rolling plains and a horizon as far as the eye can see. The smell of fresh air and the surroundings, make it an absolutely beautiful place to visit or to even live. Illinois is probably where I will end up some day, owning a farm and lots of animals. It was and still is my favorite place to visit in the United States. But, having been visiting California all of my life, it has a special place in my heart. These places are polar opposites in every way imaginable. I like being able to visit different ways of life.
