DELL Essay Example | Topics and Well Written Essays - 1250 words - 1

DELL - Essay Example The most disappointing thing was the location of the launch as the Chinese got the first experience being the aim market for Dell; evidently, this itself was substandard for the people in the west (Camp 2012). All the same, the phone looked splendid with a rare design; moreover, it had a built-in receiver and ran on an Open Mobile System. Once people heard about these and other features, the interest faded slowly; naturally, for a leading computer technology company, one would expect features such as 3G circuitry in an android phone manufactured in China. Most of the consumers also lamented about the lack of Wi-Fi in the smartphone; in fact, the only type of wireless network that the device had was Bluetooth. The touchscreen was better off with a screen resolution greater than that of the iPhone; appreciably, the camera was standard but not top class. However, to add on to the problems, the device lacked a favorable keyboard, which was disappointing as the iPhone and android Samsung phones launched before it had the same problem thus people expected an improvement on this model. Generally, the Dell Mini i3 smartphone was a downfall for the company and the only reason very few considered it was because of impressive features such as Micro SD card slot or the USB port. Essentially, Dell China and China Mobile faced the greatest challenge then, due to a lot of criticism; however, Dell took almost all the blame because this was their first smartphone and it seems China Mobile was not in support of launching the project because no updates have come up (Camp 2012). Decisively, Dell requires a new and unique smartphone to redeem the company as a whole and that particular division, definitely, the new gadget, better than the latest iPhone or android Samsung phones will meet the customers’ needs and act as a foundation for corporate social responsibility and

ONeill Cylinders Essay -- physics space

Science fiction authors for many years have written book after book exploring, as Star Trek described space, "the final frontier". While many people focus on the exploration side of space, there are some who believe that space is our next refuge. Stephen Hawking has said " I don't think the human race will survive the next thousand years unless we spread into space". While some speak of moonbases, or planet-side bases, one of the most intriguing ideas is the O'Neill Cylinder. Gerard K. O'Neill created the O'Neill Cylinder in his book "The High Frontier". An O'Neill Cylinder consists of two cylinders which counter-rotate around each other, each one has a two mile (3 kilometer) radius, and a 20 mile (30 kilometer) length. The two cylinders counter-rotate to create simulated gravity by centripetal force: everything is pushed to the outer wall due to that force. However, some design choices stem from this, some to combat the negative effects, and others to take advantage the centripetal force. Due to the nature of artificial gravity, many people might experience nausea and dizziness. To combat this, the speed of rotation would need to be decreased to about two revolutions per minute. To take advantage of artificial gravity, different parts of the O'Neill Cylinder can rotate at different speeds. In the middle of the cylinder, the artificial gravity will be smaller than everywhere else in the cylinder, and manufacturing facilities would be placed here to take a dvantage of that fact. The cylinders themselves would have six sections on them, half of them are windows, the other half is the ground. Behind each window would be a mirror so they could direct the sunlight into the cylinder, while night could be simulated by simply moving ... ... an object is at a Lagrange Point, it acts much the same as a satellite that is in geosynchronous orbit with a planet. Things at a Lagrange point are at a "fixed" place in space, which is quite an advantage for O'Neill Cylinders. Bibliography Books: O'Neill, Gerard K. The High Frontier: Human Colonies in Space 1997.

Creativity, psychology and the history of scienc Essay

Children are the most interesting people on earth to sit and watch at play. Their minds are so open to the endless possibilities that allow them to entertain each other for hours on end. Some children play house or pretend to be a mommy with a baby doll, and others pretend to be truck drivers or mechanics. There is always the inevitable play of doctor and nurse, and it is amazing at how much their little minds absorb in just a short amount of time. Adults have sometimes closed off the creative portal in their minds in order to stay focused on more important issues like marriage, work, paying bills, and making it to the gym three times a week. These routines leave little time for play or creativity, but everyone possesses the ability to be creative. Some individuals are more gifted and comfortable with expressing their creativity in positive ways. Some levels of creativity are so amazing that they last a lifetime. In a recent television interview, a country music singer commented on a recent speech given by the President of the Untied States. He quoted the President as having stated that some people have simply made enough money. This was more than an ironic statement to make considering that the United States is in the middle of a horrible economic recession. The country music singer further added that what if some people stopped their lives when they had reached a certain financial level. It was then pointed out that the now deceased actor, Danny Thomas, had taken his money and coupled it with the creative idea to open a hospital just for children who had cancer (Potter, 2009). This ambition was to accomplish the goal of treating every child with cancer without turning anyone away. The hospital is now a well recognized name, Saint Jude’s Children’s Hospital. Creativity comes from the minds of individuals who allow themselves to think beyond the realms of the societal norm. In the above instance, Danny Thomas wanted to share and to give PSYCHOLOGY 3 back to his community. In other words, he wanted to share his wealth in a way that would benefit everyone and not just himself (Davila, Epstein, & Shelton, 2007). His level of creativity afforded him the opportunity to solve the financial and emotional burdens of many parents of children suffering from cancer. It also provided children with the hope of getting better. If more individuals allowed for their creative flow to emerge beyond their own minds, there are many problems that may find resolution. Society has become too convinced to follow the herd rather than to think for themselves (Gruber & Bodeker, 2005). New innovations in medicine, counseling, education, and everyday living could all stand to benefit from the creative idea of one person. Freud was a creative thinker despite his own public ridicule. The field of medicine has benefited from genetic testing that now allows parents to prepare for an unborn child who may be born with a chromosomal defect. Teachers have developed new ways of teaching children with learning disabilities so that they can be later mainstreamed into regular classes. Everyone was born with a mind that allows them to think freely. Creativity is just one of the benefits of being human. Instead of hiding the creativity from within, why not allow it to emerge and grow. Problems could be solved and lives could be changed. Ultimately, it is up to the individual as to how and when the creativity can awaken, but psychologically, it is a gift that should not be overlooked.

The Membrane And Its Effects On Human Development - 860 Words

It is generally accepted that resting CaMKIIÃŽ ² bundles and stabilizes actin cytoskeleton. Transient activation of CaMKIIÃŽ ² relaxes cytoskeleton, promotes actin polymerization and CaMKIIÃŽ ² recruitment, and favors cytoskeleton growth. This model has been shown in both synaptogenesis (Okamoto et al., 2007) and OL maturation (Waggener et al., 2013). Based on this theory, we proposed that prolonged CaMKIIÃŽ ² activation by NMDA-R-mediated Ca2+ influx leads to destabilization of actin cytoskeleton and membrane disintegration in mature OLs. Although our experiments unambiguously showed that NMDA-R activation results in CaMKIIÃŽ ² activation, direct proof that links CaMKIIÃŽ ² activation and membrane reduction are lacking. All the existing CaMKIIÃŽ ² inhibitors†¦show more content†¦As mentioned in chapter 5, a repeated measure experiment using OLs from CaMKIIÃŽ ²A303R mice will be the best way to investigate this question. The CaMKIIÃŽ ²A303R mutant retains its ability to bund le F-actin, but loses its Ca2+/CaM binding capacity. Based on our proposed model, Tat-induced [Ca2+]i increase should have no effect on OL membrane area since Ca2+/CaM can not bind and activate CaMKIIÃŽ ²A303R, and promotes its release from actin cytoskeleton. Most of our experiments are done in mice cells. Since HIV is a human disease, we used an hBrnAgg model to try to verify our finding in human cells. We thought that the hBrnAgg model serves our experiments best because 1) it mimics the in vivo environment with the presence of all major CNS cell types, 2) myelination has been observed in the model by other investigators, thus fulfill the needs of studying effect of HIV/Tat on both OLs and myelin, and 3) the hBrnAgg model can be maintained for a long period of time (up to 60 days), made it a good model to study long-term effect of HIV/Tat. Our immunostaining experiments suggested that there are far less OLs in the aggregates than we expected. Under EM, plenty of synaptic structures, both symmetric and asymmetric, were observed in the hBrnAgg. However, cells with typical mature OL characteristics, including dark cytoplasm and nucleus, elongated, thin strands of endoplasmic reticulum; numerous mitochondria, and stacks of Golgi apparatus, were rarely
