Introduction
A stroke is a medical condition which is characterized by rapid loss of brain function which is caused by interruption in the blood supply to the various parts of the brain. It can be due to a blockage and it’s known as thrombosis or lack of blood flow known as ischemia or a leakage of blood that is hemorrhage (Feigin, 2005). It results in the person’s inability to move certain parts of the body.
Case study
The brain is designed in such a way that the right hemisphere always controls the left side of the body while the left hemisphere controls the right side of the body. This explains why Joseph’s left part of the body got paralyzed even if not entirely. This also depends on the part of the right side of the brain that has restricted blood flow.
Joseph’s left face and hand has been paralyzed, but not the rest of his arm or his leg because of the restricted blood flow to a portion of his right precentral gyrus which is known to control moments of the muscles in the left face and hand and it is the right side that controls the left side.
What is preventing Joseph from moving his left hand is because of lack of communication between neurons that is between the central nervous system and motor neurons.
Motor neurons are neurons that transmit signals from the brain to the effector cells which include muscle cells. Motor neurons form synapses with effector cells. When an action potential reaches a synapse pore which are present in the cell membrane opens which in turn allows positively charged calcium ions into the pre synaptic terminal. This causes neural transmitters which are chemical in nature to be released in a gap between the two cells and this is known as the synaptic cleft. The neural transmitter is able to diffuse across the synaptic cleft and proceeds to interact with proteins called receptors which are usually embedded in the post synaptic membrane (Sherwood, 2001). The receptors serve as ion channels which allow charged atoms to pass through pores within their structure and this is propagated along the dendrite towards the soma.
The destruction of a neuron that communicates with the motor neuron prevents Joseph from moving his hand by disruption of the transmission process. The motor neuron is not able to receive signal from the central nervous system neuron and thus it is not able to propagate the signal to the effector muscle that is the hand (Garrett, 2011).
In an adult human being the brain takes longer time to redevelop damaged neurons because the neurons are fully developed and this is because why Joseph’s brain cannot simply replace the damaged neurons immediately (Altman, 1963). Compensation might allow Joseph to regain some of the lost movements. This occurs through the neurons that were not damaged and serve extra role of transmitting signals for the damaged neurons but this takes time and it is achievable through therapy. Experimental treatment that might improve Joseph’s movement of his left hand is by slowly exercising the hand through aided extension and constriction of the hand muscles. The exercises can be done from time to time and it impacts on his nervous system by using the existing motor neurons to transmit signals to the hand. His nervous system will slowly undergo rearrangement so that it can utilize the existing neurons to control the left hand.
Conclusion
It is possible for the nervous system to recover from damage through natural processes for example compensation and reorganization. These processes enable the recovery of impaired functions for example of limbs and hands or any other impaired part. There are also experimental treatments that facilitate the growth of new neurons in a mature nervous system. Through proper treatment and therapy patients who suffer stroke do not suffer permanent disability especially because of these processes. This has greatly aided patients who have suffered strokes to be able to regain function of the affected parts through therapy.References

Neugent v. Beroth and The Estate of Salome Duran case study
Neugent v. Beroth and The Estate of Salome Duran case study
Summary of the existing Facts
Beroth on or before 1995, January began to sell to the plaintiff motor oil. Since then till November, 30th, 1995 the parties pursuant operated with plaintiffs Amoco DSA and Amoco leases, that Beroth, attained when he bought from Amoco, the oil stations. The motor oil prices were set by the Amoco DSA at their dealer buying price. These price changes immediately took effect, mainly in Amoco motor fuel sales facilitates that were by then in location, as the title to the mentioned products transferred to the dealer from Amoco. The controversy lay in the fact that Walter Beroth, the plaintiff stated that he was not aware of the price changes, made in the buying prices by the Amoco dealer. He argued that the defendant went against the Beroth DSA contract. His main contention is that the prices that Beroth was quoting were not initially in the agreement. This make up the basis of the case.
Issues/Problem Identification
The main issues in the case include the assigning of the courts trials as mistaken by the plaintiff on issues that included; summary judgment granting for defendants on claims of the plaintiff where there existed material fact issues that included; fraud, civil conspiracy, contract breach, and deceptive and unfair trade practice on their transactions.
Analysis/Evaluation
According to the plaintiff, the defendant automatically committed a breach on the 1994, October created contract by increasing the charges per gallon delivery to 1.427 cents. This perspective seems to be favoring the plaintiff however; further analysis disagrees with this since it is clear that there is failure by the evidence to prove that in the 1994, October meeting an oral contract was reached. Failure of plaintiff at bar, to prove the creation of an oral contract has aided in his failure to prove his case. There was a claim by plaintiff that Vernice Beroth or Walter at that meeting offered to the plaintiff the oil sales. However they have both denied this offer and state that they just discussed motor fuel prices. It can be viewed that he failed to avail proof for his claim. He failed in all accounts, to produce support for his accusations to counter those the alleged produced.
His evidence included showing that Beroth; acquired the said property from Mr. Peddycord, bought the station from Amoco, Assumed the Amoco DSA and Amoco lease, and on or about 18 January 1995, began supplying plaintiff motor fuel. In addition he does not have any tangible proof on the results of the meeting they had on October 1994. He was also wrong when he thought that they could be bound by the oral contract. UCC, regulations actually dictated that a contract for goods sales that exceeded above ($500.00) of five hundred dollars or more needs for some sufficient writing to indicate that a sales contract has been made and signed by those involved and those the petition is against. The analysis can conclude that since the records show that after the motor fuel started to be sold to the plaintiff by Beroth, pursuant to the Beroth DSA and Amoco, the motor fuel deliveries prices clearly exceeded $500.00. In this perspective we point out that since in the 1994, October meeting no formal contract was formed by those involved, it makes the case weak and thus, the rack price does not hold.
Recommendations
Recommendations would be on affirming that part of the courts trial should be on reviewing the plaintiffs initial claim of alleged oral breach of contract, indulge more on the counterclaim from Beroth on past due rents, also on possibility of basing a contract on oral standings that can further help bring new light to the Beroth case.
The Estate of Salome Duran case study
Summary of the existing Facts
In Taos , a widow named Macarita Sanchez owned 11.392 acres of land, she had five children and when she died in 1932, she intestate her property to her children. Cinesio, Evilia, Felipe and Donaciana, thereupon became cotenant owners they agreed on how they were going to share it orally. Salome, the mother’s brother later in 1945 took charge of the land and as such paid for the tract of land accumulated taxes and as such supposedly owned it. Since then until his death in 1998, Salome conveyed the property in joint, ownership between him and his wife, who took subsequent ownership until her death. Cinesio and Evilia after Salome’s death were the only surviving children of Macarita. They expressed an interest to the estate stating that to them the agreement had been void, since they had never confirmed if they could annul it, and this was their basis for their case.
Issues/Problem Identification
The main problem is that the uncle or guardian acquired their land through adverse possession mainly without stating clear intent. They petitioners argue that the decedent’s transfer of land to his wife was not legal and it had malice in it. In these grounds, since their kinship entitled them to have more claim, they argue that the property should be returned to them without the other parties having shares in the property.
Analysis/Evaluation
In evaluating such cases the statutes set include there being a requirement for parties claiming adverse position of land must not only give irrefutable but clear evidence of the claim, that include over ten years tax payment on the lands. The petitioners claim that even though the decadent’s possession was not more permissive than hostile, if looked at independently it is clear that the decedent still lacked a good faith color or good will on the title. In addition under the case law and the statutes interpretation it still lacked in some aspects, since many issues were unresolved. Thus it can be summed up that by denying the motion for a petition it was an error on the district courts part. That saw it pass its judgment that the decedent’s titles could only be acquired by the respondents through adverse possession.
Recommendations
With the above analysis the main problem lies, in the gap that is between the twenty years since the oral agreement was made between the five siblings. It would have been better for them to establish a more stable and recognize form of establishing their ownership as opposed to the verbal agreement. The deficiency in the verbal partition could have been sorted if the tact by then had been taken by the petitioners. By them simply doing or asserting acts that would affirm their entitleship and acceptance to the verbal or oral agreement. No such findings were ever found or made by the court or rather the district court.
In conclusion, the case should not be centralized on the extended passage of time and the hefty taxes as the grounds of dividing the property. However from the analysis of the court’s decision we can also draw our own conclusion and state that under these decisions were not in any way consistent with the Gurule requirements. These rules provide a clause for our precedent and voidable contract regarding the effect of the tax deeds issuance. It states that an issued tax deed to a person who initially had rights jointly with others to the property as a cotenant before the tax evasion or delinquency does not in any form destroy the initially held power of contingency, and it is with this understanding that it can be concluded that the petition on the property would not stand under any grounds based on these evidence.

Do you think the term routing congestion can be replaced by network congestion? Why
Congestion is when there is too much of something which prevents work from going on efficiently and effectively. Routing is the movement of data from one network to another, networking congestion is when data deteriorate because there are too many packets present in a subnet. This occurs when the number of packet data Sent to network has a great capacity than that of the network .routing congestion is a general term that is used to define the interference and difference between tracks from the supplied and the ones available. Network congestion is analogous to routing congestion because they both minimize congestion collapse in communication networks (Perlman, 2000).
The above stated definitions both describe congestion which occurs in intermediate node because of scarce resources when data is transmitted from source location to destination. In networking congestion occurs when the load on networks greater in capacity as compared to the network. This means that when there is too much traffic performance decreases and congestion increases. This means that when it reaches destination and will be dropped to intermediate routers. If routers have insufficient memory congestion increases and packet data will be lost. The only way routers respond to overloading is by dropping the packet data.
Routing congestion is similar to network congestion as networking is done through the LAN and WAN which use routers and when the number delivered is un proportional to number of packets sent the routers may not handle the extra load and packets are lost .Construction of routing table is efficient in routing to enable minimize congestion in the networks by increasing memory.
In your opinion, what is the purpose of no routable protocols? Is there a legitimate reason for having no routable protocols? Do you think they can be replaced and with another type of protocol or innovative system?
In general a protocol is a set of guidelines or rules that must be followed to help network communicate effectively. A routing protocol is a path that is assisted by a routing protocol to transmit data, share information and report changes. They are software’s that determine which route is best suited for a specific packet data to advertise (Perlman, 2000). They may include border gateway protocols (BGP) and interior gateway routing protocols (IGRP).Routed protocols are similar to Internet Protocols which is the data being transported from source to the destination. This is achieved by routers which connect two or more networks to enhance the speed of the routing process. Routers are ideal in identifying best metric routes which will assist in efficiently sending information when received. They include Interior Gateway protocols ( Duggan, 2011).
Routed protocols are safe faster and reliable to transfer data without this protocols alternative routes could not be identified if current one goes down. A no routed protocol is a communicational protocol that has no network and only addresses schemes from sending data between networks. The can only work in a routed environment if they are bridged since they are not functioned to being routed. Non routable devices have no unique network meaning can only be used between same network segments. Example is the TCP/IP (Duggan, 2011).
Non routable protocols are mostly used in the modern day world example of routed protocol internet which is highly appreciated. It does not require large time consumption to process or in overheads compact. This affects greatly the transmission of data which is faster as compared to other protocols. The main importance of using non routable protocol is because it is secure. This is maintained by the fact that is does not require additional overheads of network addresses making it fast and efficient. They check data in a data transmission for errors which assist in reducing memory lost in each data transmission.
The protocol uses less system resources and is used in Windows LAN manager for work groups to share information. Examples include Net BEUI which is Extended User Interface, Data Link Control (DLC) and Local Area Transport (LAT) .NetBEUI is a non routable protocol that is fast and was used in Microsoft networks. The Net BEUI is considered the fastest protocol in small LANS and is involved in identifying nodes and sharing information between available networks. It operates and has physical layers of OSI model.
NetBIOS is a non routable protocol that generates more traffic but with plenty of bandwidth and is essential in small networks. In routing information needs to be sent to establish link by using minimum number of segments which are held in a routing table which is assisted By Routing Information Protocol that is adapted in very router. The DLC allows communication between mainframe computers and mini computers to establish connection between computers on remote segments.
The best alternative for the non routable networks is routed networks such as TCIP/IP which allow connectivity (Duggan, 2011). .This allows for effective internet connectivity which means information can be routed anywhere and uses both systems of interior and exterior to transmit data. This protocol is best suit as it allows packet data to be taken from one source to a particular destination. This is done by gateways which are defined as layer protocol translation between devices. This model as opposed to no routable protocol is reliable, secure and was designed for scalability unfortunately it is not that fast due to traffic interference.
Internet is a major requirement in most offices today, meaning that the world has opened its eyes to the superhighway which is the worldwide web. Internet popularity has enabled the TCIP/IP protocol to be effective .In all computers at home the TCIP/IP has been connected without the owner realizing. This makes it the most widely used protocol in the world. Routers operate at operated protocol levels and they provide security but the more the routers filter down the lower the performance.
Routers are devices that are small in sizes and join multiple networks together. The device forward data between the computer networks and through information obtained from routing table it directs the packet data to the destination node. Routers are best suited in very large networks Wide area Network where information is passed over a vast distance .They use special languages such as Transfer Control Protocol or Internet protocol to identify which way is shortest and routes data packet in a network (Perlman, 2000). They are mostly used in home or small office routers to filter traffic, either incoming or outgoing based on the wired or wireless internet protocol (IP).
A routed protocol allows packet data to be forwarded and provides appropriate addressing information from one network to another. They also avoid routing loops and this gives them competitive edge over no routing protocols .They do this by using information about costs of hop, scalability, selection of preferred routes(Perlman, 2000).
