Energy production has experienced numerous landmark changings thought the century. Although there is no perfect solution found in terms of satisfying the needs for energy resources and mitigating its environmental and social impact, hydropower generation is considered a renewable energy source and alternative to fossil fuel combustion. Hydropower generation has experienced significant advancement throughout its history. However, the principle of its work is rather comprehensive. The energy of falling water is employed to turn the turbine, which is connected to the electricity generator. Furthermore, electricity is supplied through grids to industrial or domestic units. In most cases dams are ...

The safety of genetically modified foods has been a significant matter of dispute in the last years. Many people are suspicious of GMOs claiming that they have been introduced not so long ago and may bear considerable risks. However, during nearly twenty years that “bioengineered foods” have been on the market, there haven’t been documented any serious cases of health hazard due to their consumption (AMA CSAPH). Thereby, it can be stated with a high level of certainty that it is secure to eat genetically modified products. A wide range of respectable institutions supports the idea that all ...

- Introduction to Adult Nursing Nursing is an important role to play, be it for the young ones or the adults or the elderly. For adult nurses, the role is ever more enhanced because they need to look after the needs and care of the young adults all the way to the elderly patients.

Ever since its introduction into the market, several people have wondered about the mechanism of action of Apligraf. It is known that Apligraf is a bioengineered skin that helps in speeding up the rate of healing of a wound. However, Lanza, Langer, and Vacanti attest in their book, the mechanism through which Apligraf works to accelerate the rate of healing of a wound is still unknown. However, the authors in the book assert that the acceleration is made possible though the introduction of living cells and growth factors together with cytokines into the wound. The in book, the authors, under the subtitle ...

Genetic engineering is a boon to the food sector. Plants and animals are genetically modified (GM) to increase the yield, make them disease or pest tolerant and ensure nutritious food is available to all. There may be a chance for the introduced genes to pass through the food to the consumer but any harm it can cause can only be judged based on the food’s toxic or allergic properties. Unless direct evidence linking negative health impact to consumption of GM food is available, GM foods need not be prohibited. Companies have the moral duty to inform consumers about any food ...

The America youth population comprises about a third of the total population although the 2013 census showed that there was a decline in this figure. Children are taken to school from their early years of childhood to be taught and educated. By the onset of the teenage years, they are eligible to join colleges and universities to specialize on various courses and various fields of study. Equipped with this knowledge, the youth can now apply the knowledge leant to positively contribute in raising the GDP of a country. Before we enter deep into critically analyzing the input brought into multi-agency partnerships by ...

Biomedical engineering can be described as the application of engineering techniques and principles to medicine. It is a combination of expertise in medicine, human biology and engineering in the development of techniques and technologies for patient care and healthcare. According to Monzon (277), biomedical engineering is yet to be formally recognized as a profession due to its multi and interdisciplinary nature. As a result, currently there is no distinct field that addresses biomedical engineering ethics. The ethical obligations of biomedical engineers are a combination of both those of medical professionals and engineers. By studying three fields of biomedical engineering, one is able to ...

Introduction

Modifying the genetic make-up of food is a concept which has been around for centuries. Farmers have successfully improved food supply through cross-breeding different plant and animal varieties to develop organisms that yield more, taste better and tolerate harsh conditions. In modern times, this has not always been welcome. The Pure Food Campaign (PFC) was established in 1992 as a coalition of restaurateurs, farmers, animal welfare, environmental and consumer groups opposed to genetic engineered food. Around the same time, the U.S. Agriculture Department stated that it would not regulate production and shipping of Flavr Savr, which is a genetically engineered tomato from ...

Abstract

The number of people being affected by various diseases that require them to have organ transplants increases every day. Meanwhile, the amount of donated organs is extremely insufficient to meet the high demand. There is also the problem of finding a donor match for a recipient and the need to take strong medications that suppress the immune system of the recipient so that the transplanted organ is not rejected. A solution to these problems has been and is still being developed, with laboratory-grown organs holding much promise. These organs can be tailor-made using the patient’s own cells or other cell sources, ...

Introduction

Orthopedics refers to the branch of surgery devoted to the diagnosis and treatment of illness, injuries malformations and deformities of the musculoskeletal system (Goriainov et al. 2014). The system includes the muscles, ligaments, tendons, joints and bones.

Introduction:

The morality of genetic research can play out in many ways. Two broad fields of concern are that of genetically engineered organisms and the ethics involved in the use of human stem cells taken from zygotes and human embryos. Another issue is the patenting of the genome and how that affects medicines and the rights of people to “own” their own cells. Of special concern is that bio-engineering might escape and have long term adverse effects as the manipulated creations cross genetic structures with other biological elements in the environment. This paper will look at the general ethical concerns ...

Introduction.

Since the existence of Homo sapiens around 180,000 years ago, human activities have been on the rise most of them with diverse effects on the environment. Human activities are responsible for almost all the loss in biodiversity throughout the globe (Southeast Asian Affairs 2002, pp 56). Biodiversity is not only unevenly spread across the Earth but also follows complex processes determined by the current changes in environment, global warming, evolutionary history of the planet and geology. Global eco-regions recognize that whilst coral reefs and tropical forests harbor most biodiversity there are manifestations in boreal and temperate regions, mountain ...

Recommendation for overweight or the obese individual has been founded to include engagement in lifestyle modification that is inclusive of diet, behavior change and exercise. However, according to extensive studies and observations, this therapy has been noted to have short term effects that are unsustainable and therefore the obese situation frequently reoccurs. The failure of these therapies poses the following question, how does diet make one fat? Hippocrates (400) prescribed that the obese should eat less and exercises more. Despite this notion being deemed as a failure, many people still apply it to present as a weight management approach. It ...

Abstract Reliable techniques to meet the needs of patients with peripheral nerve repair injuries need to be refined. One of the strategies often used is to create a nerve guidance channel or build a nerve conduit Silicone is has been found to work well as a conduit from an injury for regenerated axon cells if it does not contain foreign components. The cycle of the cleaning treatment was repeated until the Pentane-Acetone-Heat Procedure was successful and the plated cells survived for several weeks. The duration of the plating and cell count using the cleaned silicone lasted from May 3, 2013 to ...

Few issues today raise as much heated emotion as the subject of eugenics and bioengineering. Hardly a day goes by when we do not see Congressional hearings on the ethics of stem cell research or debate in the media over some proposal to expand to boundaries of our artificial reproductive technologies. Hollywood and popular culture constantly bombard us with scenarios related to genetic engineering. Aldous Huxley’s controversial book Brave New World introduced the possibility of selective breeding of human beings as far back as 1932 (Huxley, 1932). More recently in 1970, the book Future Shock by Alvin Toffler portrayed ...

Introduction

Coevolution is used mostly in the field of biology. Coevolution is defined as “the change in the genetic composition of one species (or group) in response to a genetic change in another” . Coevolution is a reciprocal change between species that are interacting with each other. Because all species seem to have, in one way or another, interaction then everything is categorically involved in coevolution, based on this biological definition. The Berkley University webpage on coevolution describes it as a case wherein two or more species affect each other’s revolution . The coevolution is witnessed in any one of the following relationships: predatory ( ...

INTRODUCTION

The human body consists of tissues and organs that contain over 200 different cell types.1 these cells carry out all the functions required for viability and reproduction. It was argued long ago, that in some tissues, the differentiated cells have a shorter life span and that they are not able to self -renew.2 This led to the notion that such tissues are maintained by cells that have an extensive renewal capacity, and the ability to differentiate and generate daughter cells. These cells were termed as ‘stem cells”.2 Stem cells generate only the differentiated lineages of the tissues they reside in, ...
