The core values St. Leo’s represents is applicable to the debate surrounding the ACA. St. Leo represents and firmly believes in community and integrity. The ACA is reportedly designed to provide for the welfare of the community, meaning Americans at large. The issue surrounding the ACA is that many say the provisions lack integrity due to various different reasons. Regardless of these issues, integrity is often defined as doing the right thing, even when no one is watching. World leaders and policy makers have a responsibility to maintain integrity to benefit the communities in which they live, whether ...

Complications of Removable Implant Supported Prostheses

Introduction The two main complications that result from removable implants are biological and mechanical/technical complications. There is need to assess and interpret data on the incidence of complications, both biological and technical with caution. Berglundh, Persson, and Klinge (2002), found that implant loss was the most common problem, while technical complications were observable in about 60-80% and biological complications – 40-60% of the studies they evaluated. According to Sadowsky (2007), there are no specifications on the length, distribution, and number of implants; however the suggestion for non-palatal coverage designs should be a minimum of 4 implants. In case of risk ...

Introduction

Dental implants are increasingly becoming popular because a large section of clinicians believe that natural tooth restoration techniques are inferior to dental implants as implants have a longer life than natural tooth and are less susceptible to biological changes. There are various types of dental implants that support crown, bridges, and dentures, and act as orthodontic anchors and facial prosthesis. The basis of the modern dental implant is a biological process in which titanium forms a bond with bone. Dental fixture is first implanted and then a prosthetic is added. Over the years, various implant impression techniques, such as ...

ANSWER TO QUESTION 1

Introduction Biotechnology is an innovative field where biological processes are applied for the provision of genetic manipulation for microorganisms for the production and commercialisation of antibiotics and hormones amongst others. Biotechnology is a process whereby scientists use various aspects of technology to modify genes and microorganisms of living things in order to attain specific goals in the organism in which it is done. The preliminary elements of this course has shown that biotechnology is carried out in both applied and pure research. In applied research, biotechnology is used for the provision of various solutions like medicines, treatment for incurable ...

Over the last decade, the healthcare arena that includes research, education, and patient care has become overloaded with technological advances. Technology influences how nurses are educated, the way how they practice, provide and document patient care. Clinical Information Systems has already replaced paper and pencil input of information that helped to reduce errors and provide flexibility in delivering specific patient care. Vital signs including temperature and blood pressure are taken, recorded and tracked electronically, and nurses are alerted to any worrying and abnormal results. Moreover, POC bar coding, electronic medical records (EMR), personal data assistants (PDAs), and the health ...

Introduction

Quoting Marchetti, Ausubel states, “Successful societies are learning systems” (Ausubel, 1995). Organized social learning and the development of our society caused increased technological progress. Since 1400, the number of technological and scientific discoveries has dramatically increased (Appendix A). In the twentieth century, it continued its growth. It was the time of scientific and technological advances that significantly improved our living but at the same time caused environmental problems, as the creation of the internal combustion engine became one of the major reasons of the outpouring of greenhouse gases. In the twenty-first century, we have something to do with them. ...

Introduction

Studies relating to lung cancer treatment can save lives and make the lives of cancer patients more comfortable besides increasing the quality of life. According to Lardinois et al., (2003), there are three primary types of lung cancer; they include non-small cell, small cell, and carcinoid lung cancer. Statistically, non-small cell lung cancer, for example, Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma account for the highest occurrences of all lung cancers to a tune of 85% [1]. It has been established that both environmental and genetic factors do contribute to lung cancer significantly. Continued exposure to carcinogens, ionizing ...

Question

Nanotechnology is progressively being used in refining everyday products in the contemporary world. Do these products remain safe once nanoparticles are incorporated in them? What is the FDA doing in this regard?

Response

Nanomaterials hold promise for numerous and varied applications. Their miniature size gives them their distinct properties which is intrinsic to their appeal and hence scientists are at odds as they try to find out plausible side effects that come with using such nanotechnology in consumer products (Gwyneth, 2012). Their application in consumer products raises a similar conundrum as major technological progress in the past due to the ...
