A Conclusion

Submitted by mparkllan on Wed, 04/25/2018 - 19:59

Stereotypes can influence people's expectations and and keep people divided. Tayeb Salih attempts to show us that we are far more similar than different to any human, regardless of what part of the world we are from. Salih accomplishes this through the use of situational irony to demonstrate the similarities of traditions and social customs and also uses imagery to compare the real and genuine and ungenuine use of certain decorative items. Everywhere around the world there are always good people who care about their communities, and bad people who use communities for their own selfish benefit. The use of literary devices in this novel are to help demonstrate that regardless of where someone is from, appearances and expectations should always be treated as such, not as the reality.

Another example of how Persepolis’ visual style and use of imagery reinforces its themes is through its use of abstract cartoon like drawings to show how characters feel. Marjane cries on a bed and thinks to herself “ That was my last meeting with my beloved Anoosh… and so I was lost, without any bearings… what could be worse than that?”(Satrapi 71). At this point Marjane had met her uncle in prison, knowing that he would be executed before she ever gets to see him again. When thinking about her executed uncle, she imagines herself talking to God and floating in the middle of space. Scenes like this show and do not tell us how isolated and hopeless she feels and how sometimes even prayer can not make her feel better. In another scene Marjane is walking down the road with someone else and after she thinks to herself “ I saw a turquoise bracelet. It was Neda’s. Her aunt had given it to her for her fourteenth birthday… The bracelet was still attached to… I don’t know what…”(Satrapi 142). Before she realizes that someone she knows is under the rubble, she is with her friend, on a road, looking at a crumbled building. After, she is tearing up and alone in the next couple of panels, until the last one of the chapter cuts to black. These stylistic choices again do a good job of showing how alone she feels even in company.


Irony in a novel

Submitted by mparkllan on Wed, 04/25/2018 - 19:58

Irony is used throughout the novel to create an interesting contrast. In one scene a family member talks about how “Ahmadi suffered the worst torture… they burned him with an iron,”(Satrapi 51) and in another Marjane explains “My mother was right to believe it was murder… when they found his body, only his head was underwater.”(Satrapi 65) Persepolis creates a sense of irony by contrasting these scenes of dark subject matter and the lighthearted visual style with the subsequent scenes of Marjane and her friends chasing another kid outside. To go from murder to running around with a fellow student because his families political activities shows just how polarizing countrywide conflicts can be. This dramatic shift in tone happens multiple times throughout the novel and draws attention to the fact that young children sometimes have to grow up in very hostile environments.


Comparative lit

In times of conflict bystanders and revolutionaries are often both put in harm's way. Whether you flee your country, keep your head down, or actively participate in your cause, there is always a chance that you or someone close to you will get hurt. In Persepolis, an autobiographical graphic novel written by Marjane Satrapi, the audience follows the changing life of a little girl growing up in Iran during the islamic revolution.

The suffering of the innocent is a major theme of the novel, and scenes of death and imprisonment are all central to young Marjane’s life. Persepolis supports these themes in a variety of ways through the use of visual motifs, cartoon like imagery, and moments of irony that contrast the very serious topics with the relatable innocence of a young child.

Spinal cord injury conclusion

Submitted by sworkman on Wed, 04/25/2018 - 18:59

This study showed a strong method to show proof of concept. The results were conclusive in the fact that it showed movements such as reach and grasp can be restored in a patient with tetraplegia. The patient chosen had a high spinal cord injury that was eight years old; this proves that this method can be effective in severe cases and the results were from the use of the two systems, not residual function. The combination of the two systems is shown to be very effective and the electrodes being under the skin makes it easier to translate to clinical use.

The downside to this test is the expense and length of time it takes. The systems used require many surgeries to implant along with recovery time and lots of exercise to restore muscle strength before the actual tests begin. This experiment also is only a proof of concept; results for only one patient are shown so it is unknown if it would work for everyone.

Overall, the conclusion of this experiment is that restoration of movement can be successful using a combination of the FES and iBCIs systems. There were positive results for completing reach and grasp movements for this patient. Future experiments could explore how this translates to different patients with different types of injuries. The coding system could use modification since they claim a percentage of the failed attempts of movement were due to faults in this system. The feedback for these tests are solely visual so possible experiments could work on giving spatial and tactile feedback. This experiment is a large step in restoring movement so there are many possibilities moving forward.

Draft #2, week 14, studies on RP

The summary of the following study presents several genotypic and phenotypic characteristics of autosomal dominant retinitis pigmentosa. This studies also attempt to describe the physiology and the progression of the disease, paying specific attention to different mutations of the RHO gene. Since RHO codes for rhodopsin, one of the unifying characteristics seen in patients with mutations in this gene is degeneration of rods (vision in low light) before the degeneration progresses to the cones. This relays into the first sign of retinitis pigmentosa which is loss of night vision and inability to navigate in low light. Young patients begin seeing blind spots in their peripheral vision as the disease gets progressively worse. The development of retinitis pigmentosa could halt at this stage however, in the majority of cases it continues to the cones and central vision begins to fail as well. In adults, retinitis pigmentosa can lead to permanent, legal blindness (Retinitis Pigmentosa, 2018). In an early study performed by Ching-Hwa Sung et al, the researchers found rhodopsin mutations in autosomal dominant retinitis pigmentosa as well (1991). They screened 161 unrelated patients with this particular mode of inheritance for point mutations in the rhodopsin gene by using PCR and gel electrophoresis. Of the 161 patients, 39 were found to carry one of 13 different point mutations at 12 amino acid positions of rhodopsin and the “presence or absence of the mutations correlated with the presence of absence of retinitis pigmentosa in 174 out of 179 individuals tested in 17 families” (Ching-Hwa Sung, 1991). These point mutations were found in the coding sequences of the RHO gene and the most common allele, P23H, was found in 15% of the ADRP families. The individual family members also experienced gradual loss of night vision and navigation in the dark. Since this is such a low, unexpected percentage, it could be concluded that there is delayed onset of the disease or very mild disease expression. This study emphasizes how with each genetic type (autosomal recessive, autosomal dominant, X-linked) there is marked individual variation. Any particular mutation in a gene, such as the rhodopsin gene RHO, is unlikely to be present in other genetic types. This presents a setback that is faced in many attempts to create treatments/cures for retinitis pigmentosa. Because of the specificity and individualism of the gene the current progress of treatment plans is very complicated and requires special attention to the patients’ conditions

According to the Argument from ignorance (wikipedia), it says that we tend to refute hypotheses that haven't been tested yet. This is why the public sees controversy between intelligent design and evolution. Therefore they don't want the idea of ID to be taught. According to the straw man (wikipedia), we tend to refute arguments by not arguing against the actual statement but against another statement that's related to the original statement. This is why it is proposed that we not teach evolution as a fact but a "theory" (Antievolution and Creationism). 

I feel like we should just teach the controversy because we already teach things that we still don't know the truth to or cannot prove. An example would be the big bang theory. That's just a theory. We don't know if it's true or not. We can start teaching it in both science textbooks and social studies in high school.

It's about the relationship between temperature and the number of arthropods present in certain areas of buildings. We measured the temperature in different rooms of the Morrill buildings and counted the number of organisms we found on specific windowsills. When looking at the graphs, you can see that as the temperature increases, the number of arthropods increases. This shows that the arthropods like to be in warmer temperatures rather than cold temperatures.

There have been many different approaches taken to regrow degraded areas of the Amazon rainforest. Humans have acted as seed dispersal agents with some success (Gagetti, 1998) but seeds are a food source for many animals and constant seeding of an area is necessary to overcome predation.  Research has also been conducted on the importance of avian foragers for seed dispersal of fleshy fruits, which showed that birds are the main seed dispersing agents in many forests around the world (Puckey, 1996). In light of this previous knowledge, our study looks to understand the role of fruit color preference in selected Amazonian parrot species.  The information gleaned from this study will be used as a stepping stone in directing the selection of fruit-producing plants that will attract parrots to areas of degraded forest. We hope to support the use of frugivorous birds as a potential seed vector in rainforest restoration.

Thyroperoxidase attaches iodine to tyrosil residues. When TSH stimulates the thyrocite it also triggers an endocytoic catcher of material that brings it into the cell that fuses with a lysosome carrying various enzymes that cleave and fold thyroglobin so as to bring the tyrosil residues together. Thyroid hormone is a diphenyl ether with four iodines and iodines are negatively charged atoms. The outer ring is away from the amino side and the inner ring is closer. When these are unattached, T4 is converted to T3. Clinically, if you have thyroid disease, T4 and T3 are not the only things the doctors look at. They also look at reverse T3 which is produced by this unattachment.
