Solar Energy
~Some history, types, and facts~
In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on fossil fuels.
Using the sun for its heat and energy is not a new idea. It has been around for thousands of years. The first record of sun being utilized for energy and heat dates back to 400 BC. The Greeks designed their buildings and oriented their houses to utilize the sun during the winter and obscuring its hot rays during the summer. The Romans then continued on with harnessing the suns energy by developing window glass that allows the sunlight to come in, but traps solar heat. The Romans even put the sun in their legal system as to make sure that every house had so much access to the sun.
The first solar water heaters came into play in the 18th century. A French-Swiss scientist in Maryland did an experiment to see how much heat window glass would actually trap. By building a box and putting different glass tops on it, he learned he could reach the boiling point inside the box. Another person developed this idea and decided to put tanks of water into them, and sure enough that w...

The media play an indispensable role in modern life, and are considered amongst the most powerful and inaccurate sources of social information, education and entertainment. Our mass media is an electronic (TV, film, video, videogames, internet) visually dominated media with print (newspaper, magazine)...
Attention Getter: Let’s look ahead fifty years and see what the world is like. Imagine a world that is in total war with no end in sight. The cause behind this war is simple, oil. Everyone is fighting over those last few reserves of oil. How can this future be prevented? The answer is solar power.
Nursing has developed from its original roots, to become a personal philosophy to those who practice it. This paper describes my personal philosophy of nursing that I plan to practice in my own personal career. I believe that nursing is founded on the principles of it being a helping process with a focus on interpersonal relationships between a nurse and someone else. Nursing not only involves treating an illness, but it also provides quality patient-centered care. My philosophy involves having a strong base knowledge of medicine as well as being able to provide compassionate patient-centered care. I believe nursing is holistic and committed to achieving the best patient outcome. My belief of nursing being holistic is that it involves a person, environment, health, and nursing. I also believe that it is extremely important for nurses to be able to work in interprofessional teams as well as work together with other healthcare professionals to stimulate superior patient care. My personal nursing philosophy with be something I continually follow and strive for throughout my career.
Nursing is what has brought us together. We have started our Bachelor Completion to further our education. It has not taken me too long in this program to reflect about what the Associates in nursing and the Bachelor Completion mean to me. I consider that during the Associates, I learned the skills to become a nurse and now, I am learning to understand and appreciate what is to be a nurse.
The X and Y chromosomes are thought to have evolved from a pair of identical chromosomes, known as autosome. The mammalian males are heterogametic (produces X and Y chromosome bearing sperms in equal proportions), and the females are heterogametic (all female gametes are X bearing). It was found that Y chromosome has high repetitive DNA sequence content which consists of pseudogenes and does not have any function (Delbridge et al., 1999). In males, Y chromosome consists of SRY gene which triggers embryo development as male. Y chromosome is the smallest chromosome consists of 2-3% of haploid genome and contains between 70 and 200 genes (Quintana-Murci et al., 2001). Y chromosome consists of 2 arms- short arm (Yp) and long arm (Yq). These arms consist of 2 pseudoautosomal regions PAR1 and PAR2 which recombine with their homologous regions on X chromosome. The absence of recombination makes genetic mapping of the Y-specific region impossible, and the ...
Each gamete, both sperm and ova, has 23 pairs of chromosomes that match up creating a zygote. A man and a woman can produce more than 8 million versions of their chromosomes to create an astronomical number of offspring, each unique (Berger p 49). Small variations or repetitions, called alleles, can make a notable difference the different characteristics of a person (Berger p 49). The 23rd pair of chromosomes is significant in all zygotes because it’s the gene that determines whether a person will be male or female. The female is designated as XX, while the male is designated as Xy. “Alleles interact in a dominant-recessive pattern, in which one allele, the dominant gene, is far more influential than the other, the recessive gene” (Berger p 54). A carrier is a person who inherits a recessive gene that is not expressed in the phenotype, or the observable characteristics (Berger p 54). The prenatal development is divided into three main periods; germinal (the first two weeks), embryonic (week 3 through 8) and the fetal period (week 9 up to birth). The germinal period involves the first two weeks after conception and is characterized by rapid cell division and the beginning of cell differentiation (Berger p 57). The embryonic period includes the growth of crucial
“Out of Print” written by Eric Alterman is a very informative article. It relates to me in a major way considering that I’ve been interested in journalism all of my life. I get my daily news from CNN, the thought of reading a newspaper never crossed my mind.There has been a major decline in newspapers due to technology’s rapid advancement. Is this a good shift in our society? How long will print journalism be used? Many scholars believe that newspapers will not be around much longer. We must adapt with the technological changes in our society. Many also believe that newspapers will always be relevant. I believe that newspapers have no worth in today’s society. Why do we need them? We can simply access the news via cell-phone or computer. “Independent, publicly traded American newspapers have lost forty-two per cent of their market value in the past three years, according to the media entrepreneur Alan Mutter.”
Solar is a viable alternative energy source with solar panels becoming more affordable and more efficiently designed.
Sperm sorting was initially developed as a means to regulate the gender of offspring in cattle. Sperm sorting is achieved through exploitation of the size difference between the X and Y chromosome. The X and Y chromosome are those that will determine the gender of an offspring. The egg of a female contains two X chromosomes, and each sperm from the male contains either an X or a Y. If the sperm that inseminates the egg contains a Y chromosome the egg will mature into a male, if the sperm that inseminates the egg contains an X, the egg will mature into a female. The X chromosome is approximately three times as large as the Y chromosome.
The print media industry has changed radically with the development of the internet, as computerized stages are picking up ubiquity, while print daily papers are losing gatherings of people. This has constrained most print media
Internet and digitization had deeply affected media and publishing sectors; consequently, it created a new space for competition. The Newspaper Publishing industry, for example, according Kaczanowska (2013) is in a dying phase of its life cycle as escalating competition from other forms of media, particularly web-based outlets, limits its market, that’s why newspaper publishers are moving most of their content to digital platforms to maximize its value. Picard (2009) elaborates that journalism must innovate and create new means of gathering, processing, and distributing information so it provides content and services that readers, listeners, and viewers cannot receive elsewhere. Meanwhile, the economic foundation for the traditional newspaper businesses is collapsing and the gathering and distribution of news has become more widely dispersed (Downie Jr. & Schudson, 2009), while online there are no added costs for physical transport and delivery and therefore online distribution costs are significantly lower than the distribution of physical content (Boczkowski, 2005).
Print and Electronic media is refer to two different thing that are used to transmit and to deliver the information. We are living in a hastily sprouting and modernized era where technology is taking charge in every walks of our life. This technology may come with many advantages and disadvantages as well. Every improvement is due to rapid modernization, development of old management methods and the use of new technology to make things even better. The growth of modernization simultaneous increases the human exigency for knowledge. Media serves an important function in keeping people informed about the events and innovations around the globe. This information may reach us in two forms, either through print media which is the oldest method, or the other one can be electronic media. With the improvement of electronic media during past few years and daily reports on achievements, electronic media has dominated over print media
As technological advancement continue to unfold, more people, especially the youth depend more on digital media for their news rather than on print media like our community newspapers. Newspapers have gradually been relegated into a less prominent facet of communication. Newspapers are now seen by most young people as a boring means of acquiring news and they rely more on entertaining sources like the internet or television, for obtaining news and information about what is going on around them.
Currently our society is in the midst of a media shift. Although there is still a need for traditional media, online media is finding its place in consumers needs. It’s important for professionals in the journalism industry to take note and understand the direction this change is taking.
