An Examination of the Machine Gun - 920 Words

Weapons of war are useful in killing human lives and causing widespread destruction and terror. The machine gun is such a weapon that has allowed for the mass extinction of those on the receiving end of its power. The purpose of this essay is to examine the machine gun in a historic perspective in order to contextualize its practicality and importance in modern history. This examination will describe the development, the current impact and the future of this tool of war in order to reveal the importance of their presence. The development of means to extinguish human existence usually arrives out of necessity. Cantrell (2012) described the birth of the machine gun by Richard Gatling as a quantum development in the evolution of firearms. Ironically, Cantrell supposed that Gatling created a weapon so devastating and superior in its firepower that opposing armies would have no chance of victory. While Gatlings intentions seemed well placed, it seems that this idea perhaps has backfired . The machine gun was introduced in the American Civil War around the year 1862 in order to serve as a deterrent for weaker forces to attack. Firepower was concentrated in this tool so that one person operating a Gatling machine gun would replace many men on the battlefield. Essentially this invention permitted for more casualties occurring at a more rapid pace. The early version of this gun had 5 to 10 barrels arranged in a cylinder revolved by turning a hand crank. It was made inShow MoreRelated Yojimbo : Ideology and Interpretation Essay1180 Words   |  5 Pagesthe conflict of man versus machine.

What Is The Alternative Lengthening Of Telomeres - 900 Words

DNA replication results in the gradual shortening of telomeres over time, leading to the activation of senescence or apoptosis. Therefore, telomere length is a key biological signal to limit the indefinite proliferation of somatic cells (Roumelioti, et al., 2016). However, cancer cells can overcome telomere shortening by synthesising a new telomeric DNA from an RNA template through the expression of telomerase (Roumelioti, et al., 2016). Alternatively, 10-15% of human cancers utilise a DNA template in a homology-directed synthesis mechanism called alternative lengthening of telomeres (ALT) (Cesare Reddel, 2010). However, the process by which DNA damage such as telomeric shortening results in the execution of homology-directed synthesis,†¦show more content†¦However, ATR, Rad51 and Hop2 were not required for break-induced telomere synthesis in ALT cells and in fact, knockdown of each gene increased the levels of nascent telomeres. To further support their findings, Dilley an d colleagues studied VA13 HOP2 CRISPR clones lacking Hop2 protein expression and found that no telomere shortening took place. From these findings, the authors could therefore propose that break-induced telomere synthesis and ALT telomere maintenance can occur independently of Rad51-Hop2 and ATR. Dilley and co-workers subsequently determined that the replicative DNA polymerase Pol , including POLD3, POLD4 and POLD1 subunits, were instead required for break-induced telomere synthesis. Whereas Pol , Pol -primase and MCM2-7 replicative helicase were found to be nonessential and were recruited at far lower levels. The POLD3 subunit is also part of the Pol ÃŽ ¶ complex involved in translesion synthesis. However, the REV3L catalytic subunit of Pol ÃŽ ¶ was not required for break-induced telomere synthesis, suggesting POLD3 primarily acts through Pol . This major role of POLD3 has been supported in studies that revealed POLD3 depletion resulted in decreased frequency of replicated ALT telomeres (Roumelioti, et al., 2016). Overall, the results by Dilley et al led to the suggestion that an alternative replisome is required for ALT telomere synthesis. Having proven that Pol is dominantly recruited to TRF1-FokI damage sites, Dilley et al set outShow MoreRelatedScientific Literature Focused On Chromosomal Dna And Dna, Blood Leukocytes, Sputum, And Buccal Cells2398 Words   |  10 PagesChromosomal Telomere Length (TL) In Blood Leukocytes, Sputum, and Buccal Cells as It Relates to Cancer Occurrences by: Andy Barajas Bio 490, Fall 2014 Department of Biological Sciences California State Polytechnic University, Pomona Abstract This is a conglomeration of scientific literature as it relates telomere length in blood cells to the occurrence of cancer.

We will write a custom essay sample on Life, Liberty, and the Pursuit of Happiness or any similar topic only for you Order Now It describes the tragedy of a typical southern lady, Miss Emily, who is deeply victimized in her character and mind by the conventional system of the South and patriarchy; thus even though she wants to fight, she still fails to confront and deal with the changes caused by the shock of northern industrialization all by herself and finally leads to destruction and self-destruction on the way of pursuing happiness. This essay concentrates on exploring the character of Emily with the efforts she has made for her life and especially the reasons for her failure in â€Å"fighting† from the three aspects as Life, Liberty, and the Pursuit of Happiness, (the well-known phrase applied from the United States Declaration of Independence). 1. The Backup of Early Life As a descendent of the southern conventional noble family, Emily was born in the environment full of the thought of feudalism and hierarchy which makes her acquire not only the attitude of arrogance and indifference to common people, but, most importantly, the habit of obedience to her father. Before her father dies, he is the only one Emily could rely on in her family. Therefore, there should be no blame to her that she depended on her father when she was still young, just as most of us would depend on our parents during our childhood and youth. However, the fact the she gets to be thirty and is still single reveals the abnormality of the dependence. Actually, it is no longer pure dependence on her father. Instead, the dependence has developed into over obedience which then is taken advantage of by her father to control her completely under the constraint of the old southern tradition. The control is just described by William Faulkner as the tableau, â€Å"Miss Emily a slender figure in white in the background, her father a spraddled silhouette in the foreground, his back to her and clutching a horsewhip, the two of them framed by the back-flung front door†. The father, a typical symbol of patriarchy, clutching a horsewhip, acts as a tyrant. It’s him who holds the Griersons always a little too high for what they really are and uses his horsewhip, which exactly symbolizes patriarchy, to beat off all of the young men who come to make proposals to his daughter, Miss Emily, believing that no one is quite good enough for her. In fact, in his opinion, none of the young men are quite good enough not for his daughter, but for the old southern tradition and its dignity. He never regards Emily as an independent individual. On the contrary, he regards her as the tool to maintain their dignity in the conventional system. However, Emily has been regarding her father as the whole backup of her life since she was born. What’s more, she has been in this state for more than thirty years. She has long been used to this dependence and even allows this kind of dependence to conquer her strong desire for free life and love. To her, this dependence is just her whole life. Therefore, when her father dies, she cannot accept the fact because her father is her whole dependence and the dependence is just her whole life. Her father’s death has also deprived all the hope of her life. Her father and the old tradition her father represents are the root of Emily’s tragedy; thus, her father’s death should be regarded as the chance for Emily to free herself from the constraint of the conventional system. It’s the beginning of Emily’s fighting for her own life, liberty and happiness. 2. Liberty Getting rid of her father’s control is just like releasing from a prison. After a long time of being sick, she is seen again with hair cut short and looks like a girl, which declares the beginning of her liberty. However, Faulkner describes her as resembling to those angels in colored church windows—sort of tragic and serene. The word of â€Å"tragic† seems to have indicated the sad ending of Emily’s life even though she has the chance to gain liberty. And the reason lies on Emily’s wrong interpretation of liberty. From the description by Faulkner, after her father’s death, the character of Emily appearing before the readers is still such an arrogant and indifferent person typically symbolizing the old tradition. It is clearly known by the readers that actually Emily never frees herself from the fetter of the conventional system even though she has gotten rid of her father’s control. However, Emily sees her liberty from a different angle. To her, liberty means to live in a way she has long been used to at her own will. Since her father died, nobody and nothing can ever take her under control any more. Therefore, she ignores all the others’ denouncing the smell of her house, vanquishes the new generation’s demanding her taxes and rejects the newer generation’s attaching a mailbox. She still carries her head high enough—even when others all believe that she is fallen, because the way of living she has been used to is just to maintain dignity as much as she can in the environment of the old southern tradition. She refuses to free herself from the conventional system because it’s the very place she feels relatively free. In contrast, the new world with all those changes caused by the shock of northern industrialization is where she will feel unsafe, uneasy and uncomfortable. Similarly in the film The Shawshank redemption, the two people, the old log, Brooks, and one of the protagonists, Red, have much difficulty in adjusting themselves to the life outside after they get their parole from decades of imprisonment. Brooks even commits suicide and Red can never pea unless asking for permission. And Emily has also been imprisoned for more than thirty years which has made her long ago assimilated by the old tradition. Emily has made efforts for her life and liberty after her father’s death. Unfortunately, she interprets her liberty in the way which is against the development of the new world both in aterial and spiritual aspects. And her false interpretation is still due to the over thirty years’ imprisonment of patriarchy and the conventional system of the South. 3. The Pursuit of Happiness Even though the living style has been assimilated by the convention, there is still something that everyone is born with including Emily. That is the desire for happiness. Emily lives in her own old world but all alone. She earns liberty but lacks happiness. Therefore, when Homer Barron shows up, she believes that he is the source of her happiness and makes up her mind to grasping the slight of hope. However, the chance of gaining happiness is ruined again by the conflict between her old world and the shock of northern industrialization. What’s worse, finally she leads to the road of destruction and self-destruction by her extreme desire resulting from patriarchy and the old tradition’s severe oppression Homer Barron, a Yankee, comes from the north and symbolizes the northern industrialization, which is definitely against the old tradition and even some basic principles of Emily’s own old world such as the feature of dignity. But on the other side, he seems to Emily the hope for her happiness. As a woman oppressed by spiritual loneliness for such a long time, the desire for love and happiness is strong enough to for Emily to conquer the continual restraint of conventional hierarchical thought. As a result, she goes out of the old house, which symbolizes the convention, with her head high and together with Homer Barron with his hat cocked and a cigar in his teeth, reins and whip in a yellow glove driving in the glittering buggy on Sunday afternoons. She even decides to marry him by buying a complete outfit of men’s clothing regardless of all the objects and conflicts. During this period, she has gradually become deeply trapped in the love and happiness with Homer Barron. She has been oppressed by patriarchy and the southern convention for more than thirty years, and now the love she is experiencing is so unique and incomparable that it has become the whole happiness of her life and that it is impossible for her to let it go. If Homer Barron isn’t going to leave her, then the love and happiness will certainly continue. However, as the symbol of northern industrialization, Homer Barron holds a completely opposite attitude towards the relationship with Miss Emily. He just regards it as a pure way of entertainment without any responsibility, which is a sharp conflict between not only Homer and Emily, but also the morals of northern industrialization and the old southern convention. Under the pressure of the conflicts and the long-term victimization by patriarchy and the convention, Emily’s character and mind has been completely deformed. In the end, to prevent the happiness from disappearing, Emily takes drastic measures as killing Homer and let the body stay with her forever so that her love and happiness will also never leave. This measure finally destroys her whole life and leaves her a complete tragedy as well as Homer Barron. In this extraordinary short story, the character of Emily William Faulkner created has made some efforts to earn her own life and liberty and even persist in the pursuit of happiness. However, her life is based on patriarchy and the conventional system of the South for more than 30 years; the liberty she goes after is still trapped in the old tradition; and her pursuit of happiness comes across the conflicts between the southern old tradition and the shock of northern industrialization. All of these negative factors lead to the final tragic destruction. References Olga W. Vickery. The Novels of William Faulkner: A Critical Appraisal [M].

Walter Pater and Luca Dell Robbia Aesthetic Ideas Essay Example For Students

Walter Pater and Luca Dell Robbia Aesthetic Ideas Essay A sea of an aromatic royal blue is what first caught my eye in the Museum of Fine Arts. A color so captivating it was almost calling my name. Luca Della Robbias sculpture Virgin and Child with Lilies ? is what I choose to describe. Out of all of Della Robbias sculptures, why did I choose this one? While viewing the sculpture I felt almost a connection with the subjects projected in the art. The mother had only eyes of love watching her baby curiously grabbing at nearby flowers. The angels above also seemed to be watching over the pair; approving of the mothers loving embrace and ecstatic over the childs curiosity and seemingly future genius. The art makes me feel a sort of peace or serenity. Seeing the mother care for her child reminds me of my own mother; it brings me a feeling of nostalgia. The royal blue sky reflects a calmness in me that really has me enjoying the art. Giving me a feeling of pleasure, the art has me totally engrossed in only it. In The Renaissance: Studies in Art and Poetry ?, author Walter Pater describes what he believes a true aesthetic critic should possess and feel when they examine art. We will write a custom essay on Walter Pater and Luca Dell Robbia Aesthetic Ideas specifically for you for only $16.38 $13.9/page Order now One thing Pater says an aesthetic critic should do is to see the object as it really is, instead of abstractly define art or beauty. The critic should instead focus on the effects the work itself provokes. Pater asks a series of questions pertaining to the art. Doe does this art affect me? Does this art make me feel pleasure? What is this specific arts meaning to me? All of these questions should come up when really describing a work of art. Notice how Pater brings up the individual in every question. An aesthetic critic should focus on how that art made them feel and reach to have their best ideas on the work come through. When Pater talks specifically of Luca Della Robbia he conveys how the Tuscan artist has expression in his pieces. The whole essence of their work is expression, the passing of a smile over the face of a child, the ripple of the air on a still day over the curtain of a window ajar. ? (Pater) Luca Della Robbia overcame limitation or hard realism (one sided presentment of mere form) in sculpture. He did this by combining high art and low art (Michelangelo and Greek sculptors) to create both passion and pure form. Pater discusses how you must bring whats inward to the surface to create expression. If I had not ever read Pater, I dont think I would have noticed the piece of art. Remembering Paters advice to the critic, I really asked myself how the art affected me. I noticed how the art individually made me feel and not how it was made for the public; which is something I would not do otherwise. By reading the Luca Della Robbia chapter I was able to witness how Della Robbia really brought new life to his work with color to a could be ordinary sculpture. I really saw how Della Robbia combined high and low art, just like Pater said. The art had a feeling of expression. I saw how hard realism was overcome. I felt as though the piece showed precise details; like the look of the mothers loving face and the childs curious glance. Della Robbia really brought life to the piece, which made it very easy to enjoy and understand. In conclusion, Luca Della Robbia was a very influential artist, that combined sculpting and works of art. He used expression. Because of reading Pater I was really able to understand the art I was looking at. I learned how to really criticize something art I would probably have not looked twice at. I noticed new details and emotions.

buy custom Solving All-Band Interference essay The majority of up-and-coming radio technologies for Wireless Personal Area Networks (WPAN), such as the Bluetooth protocol, are intended to function in the 2.4 GHz ISM band. Given that both Bluetooth and IEEE 802.11 devices use an identical frequency band and might aptly collaborate in a laptop or might be crowded on a desktop, interference can set in motion some noteworthy performance disturbances and setbacks. The key purpose of this paper is to explain the interference issue and to accentuate a coexistence structure and few solutions for these technologies to run under an ideal setting. A WPAN is a wireless and extemporized data exchanges structure that permits a number of autonomous devices to correspond. WPAN is differentiated from further kinds of wireless networks in terms of range and capacity. Communications in WPAN are generally restricted to an individual or entity and are able to broaden 10 meters through all paths. This is distinguished to Wireless Local Area Networks (WLANs) that normally cover up a fairly ranged geographic zone, such as a sole building or site. WLANs function in the 100-meter scale and are created to boost, instead of substituting customary cabled LANs. They are frequently employed to generate the closing little distance of connectivity between the central network and client. Users are able to link up the network with no worries of seeking a position to connect their processor or being obliged to put in costly modules and cables. The Bluetooth Specifications In this segment we provide a short outline of the Bluetooth technology (Group B.S.I., 1999). Bluetooth is a limited (0 m-10 m) wireless connection technology intended to substitute non-interoperable proprietary wires that link together phones, laptops, handhelds and additional convenient devices. Bluetooth functions in the ISM frequency band opening at 2.402 GHz and finishing at 2.483 GHz in the USA and Europe. Two or more components conversing on equal channels bring about the formation of a piconet, where one unit works as a master and others function as slaves. A channel is identified as a single pseudo-random occurrence bounding succession originating from the master devices 48-bit address and its Bluetooth regulator rate. Slaves in the piconet coordinate their timing and frequency bounding to the master, via a set up connection. The IEEE 802.11 Specifications The IEEE 802.11 regular [802] identifies both the physical (PHY) and medium access control (MAC) level protocols for WLANs. The IEEE 802.11 standard requires three diverse physical conditions: frequency hopping (FH) broad spectrum, direct sequence (DS) broad spectrum and infrared (IR). The broadcast strength for DS and FH devices is distinct at an upper limit of 1 W, where the recipients sensitivity is adjusted to -80 dBmW. Antenna gain is restricted to 6 dB highest. In this context we concentrate on the 802.11b requirement (DS broad spectrum) as it is mainly and mostly installed in addition to being in the identical frequency band as Bluetooth. Interferences The 2.4 GHz ISM band tolerates prime and minor functions. Minor or secondary operations comprise no authorization however must comply with regulations identified in the Federal Communications Commission Title 47 of the Code for Federal Regulations Part 15 (Com, 1998), corresponding to the overall emitted power and the deployment of the spread/broad spectrum inflection plans. Interference between the different uses is not tackled provided that the regulations are adopted and applied. Hence, the main disadvantage of the unuthorized ISM band is that frequencies are required to be allocated and latent intervention endured. As the spread/broad band and power systems are moderately effectual in coping with numerous users in the band, given that the radios are physically disconnected, the same does not hold true for close immediacy radios. Compound users, counting self-interfering of numerous users of the identical function, comprise the upshot of elevating the noise ground in the band, lea ding to a reduction in performance. The influence of interference might be yet more brutal, when radios of distinct applications employ the same band, while situated in near proximity. Consequently, the interference issue is featured by a time and frequency overlie, as described in Figure a. In such a case, a Bluetooth frequency hopping scheme absorbing 1 MHz of the band is revealed to partly cover a WLAN Direct Sequence Spread Spectrum indication absorbing a channel of 22 MHz bear in mind that the collision overlap instant relies on the frequency hopping model, and the transfer allocation of the Bluetooth and WLAN systems all together. Solutions to the Problem of All-Band Interference Lately, there have been numerous efforts to enumerate the weight of interference on mutually the WLAN and the Bluetooth performance. Printed upshots can be categorized in a minimum of three classes, conditional on whether they hinge on study, model or investigational depths. Systematic products founded on likelihood of packet collision were acquired by Shellhammer (2000), Ennis (1998) and Zyren (1999) for the WLAN packet failure and by Golmie et. al. (2001) for the Bluetooth packet slip. Even though these analytical products are most likely to portray a prior order estimate on the effect of interference and the performance degradation, they frequently generate a number of postulations relating to the traffic allocations and the process of the media access protocol Interference in the 2.4 GHz ISM spread 7, the thing that might make them not as much of a reality. More prominently, for the breakdown to be good, joint interference that can alter the traffic allocation for every scheme is regularly overlooked. Conversely, investigational upshots, counting the ones achieved by Kamerman (2000), Howitt et. al (2001) and Fumolari (2001) can be deemed more precise to the detriment of being excessively explicit to the performance tested. In effect, there is a selection of business-controlled actions oriented upon coexistence in the 2.4 GHz spread. The IEEE 802.15.2 Coexistence Task Group was established so as to assess the performance of Bluetooth devices hindering the WLAN devices and expand a pattern for coexistence, which will comprise of a variety of suggested observations and probably adjustments to the Bluetooth and the IEEE 802.11 standard requirements (802 11, 2007), that facilitate the accurate function of these protocols under a collaborating manner. Together, the Bluetooth Special Interest Group (SIG) created its personal mission group on Coexistence. Both the Bluetooth and the IEEE functioning groups, preserve cooperation affiliations and are observing equivalent approaches for diminishing the force of interference. The suggestions measured by the groups vary from shared systems, aimed for Bluetooth and IEEE 802.11 protocols to be executed and applied within the same mechanism, thus to completely self-re gulating solutions that depend on interference discovery and evaluation. A continuum/spectrum analyzer is the preeminent instrument to verify the occurrence of any movement on a frequency. The Carrier Busy check, presented in the Test list of options of Cisco Aironet links tasks as a replacement for this piece. Spectrum analyzers are mechanisms that one can employ to recognize and calculate the power of interfering RF signals. When a person spots the source, he is either capable of eliminating the source to remove RFI, or appositely protect the source. Narrowband indicators do not interrupt precedent data RF signals crosswise the whole RF band. Thus, one can as well select an exchange channel for the bridge where no narrowband RF intervention exists. For instance, if redundant RF signals disturb a channel, for example channel 12, one can arrange the wireless bridge to employ another channel, say channel 6, where no narrowband RFI takes place. Here are a few constraints one must verify, if there is a big number of cyclic redundancy check CRC slips: Line of Sight (LOS) - Test the LOS linking the transmitter and the receiver and verify that the LOS is apparent. Radio Interference - employ a channel that comprises lesser radio interference. Antennas and Cables - guarantee that the antennas and wires are suitable for the radio link space. Cisco suggests a site survey to facilitate the reduction of such faults. Royal Philips Electronics recently declared new 802.11b low-power Wireless Local Area Network (WLAN) and Bluetooth semi-conductor 'system-in-a-package' (SiP) solutions, purposely crafted to function simultaneously in tiny model-feature devices such as smart phones, PDAs and other handy devices. Philips has expanded specific hardware and software, inserted and integrated within its WLAN and Bluetooth SiPs, in order to respond to this test.Moreover, a user can exploit a cellular phone featured with a Bluetooth wireless receiver to generate a call at the same time as utilizing the exact device to concurrently confirm data on the Internet, through a WLAN network, devoid of any interference. Mobilian Corp. shaped the simulation for the aim of describing Bluetooth and Wi-Fi interference upshots, and furthermore identifies solutions that would make coexistence and simultaneous function, possible. This extremely practical C program precisely outlines the conduct of both the PHY and MAC of Bluetooth and Wi-Fi together. Actually, most of the essential parameters argued, can be assorted to reproduce diverse states. If neither of the mentioned steps adequately tackle the issue, then one should consider employing a 5 GHz (802.11a) NICs and access points at any rate, for the projected future, a user can entirely keep away from RF interference in this spread. He will as well collect a great deal of high throughput; nonetheless, the narrow series might need additional access points and high outlays. Another approach is Ericsson's realization of AFH, Adaptive Frequency Hopping; it is put together on proficient algorithms and filters that allow the link administrator to effectively execute Channel Assessment, and thus, guiding AFH to be significantly more efficient than is needed by the Bluetooth Specification. The subsequent standard has been functional when expanding an AFH result for incorporation with Ericsson's Bluetooth IP model solutions: Trivial effect on CPU weight for nominal power expenditure Minimum trace regarding both software and hardware Simplest integration with a broad selection of radio chips Ericsson's completion of AFH is moreover improved and reinforced by further methods that target an empowerment in sound feature. A good example would be an Extended SCO, an additional new quality of Bluetooth 1.2. This purpose makes it likely to notice and re-broadcast lost or corrupted voice packets through a two-way course, with almost no cutback of instantaneous performance.

Trance Dance of the San

Trance Dance of the San The trance dance, which is still practiced by San communities in the Kalahari region, is an indigenous ritual by which a state of altered consciousness is achieved through rhythmic dancing and hyperventilation. It is used for healing sickness in individuals and healing negative aspects of the community as a whole. The trance dance experiences of San shaman are believed to be recorded by southern African rock art.    San Healing Trance Dances The San people of Botswana and Namibia were formerly known as Bushmen. They are descended from some of the oldest surviving lineages of modern humans. Their traditions and way of life may be preserved from ancient times. Today, many have been displaced from their native lands in the name of conservation, and they may be unable to practice their traditional hunter-gatherer lifestyle. The trance dance is a healing dance for individuals and the community as a whole. It is their most prominent religious practice, according to some sources. It can take several forms. Many adults, both men, and women become healers in San communities. In one form, the women of the community sit around the fire and clap and sing rhythmically while the healers dance. They sing medicine songs that they learn from their youth. The ritual continues all night long. The healers dance in counterpoint to the rhythm in single file. They may wear rattles attached to their legs. They dance themselves into an altered state, which often includes feeling a great deal of pain. They may scream in pain during the dance. Upon entering the altered consciousness through the dance, the shamans feel healing energy awaken in them, and they are careful to channel it to those who need healing. They do this by touching those who have sickness, sometimes generally on their torso, but also on body parts that are affected by the illness. This can take the form of the healer drawing the illness out of the person and then yelling to eject it into the air.
