King John

In 1210, King John led to Ireland an army that consisted of the feudal levy of England, mercenary knights from Flanders, and a large force of Serjeants and crossbowmen, supported in the course of the campaign by some seven hundred ships. Money paid out for the ships totalled over £3,800, while wages for the crossbowmen and Serjeants topped £2,380. The 1210 Irish expedition was an impressive operation and showed Angevin government at its most effective. Modern historians, needless to say, have been impressed by the organisation and scale of the undertaking. What makes John’s Irish campaign not only impressive but terrifying was that, in one sense, it was all done to hunt down one man and his family.

Literature Result

Background: The performance of professional athletes is very important for the achievement of athletes. The athlete's performance is influenced by various factors, namely environmental factors such as training, diet and sociocultural. One important factor that also affects the performance of athletes is genetic factor that are currently being studied. One of the genetic factors believed to play a role in athlete's performance is the Alpha Actinin-3 gene (ACTN 3). Purpose : to examine how the Alpha Actinin-3 (ACTN 3) gene polymorphism causes variation among individuals in athletic muscle performance. Method : study literature. Result : The ACTN 3 gene codes for the ?-actinin-3 protein which plays a role in producing a large force of contraction (rapid forceful contraction). The genetic variation of the ACTN 3 gene causes several variants of the ACTN 3 gene that play a role in the athlete's muscle performance.Keywords: Polymorphism, ACTN Gen 3, Muscle performance.

Abstract Active disassembly (AD) is an emerging field of research in design for disassembly that enables a cost-effective nondestructive separation of product components. It is based on using active joints and fasteners that enables the self-disassembly of products without any direct contact between the product and the operator, where these joints and fasteners must be inserted in the product during its design and manufacturing phases. Generally, active joints and fasteners are made of smart materials such as shape memory alloys (SMAs), that can generate the necessary disassembly forces required to separate the different components of the product. Most of the exerted effort in this field of research was focused on separating products requiring small disassembly forces either in the electronic or automotive sectors. All these active disassembly applications were based on using shape memory alloy snap fits, clips, or wires that are characterized by their ability to generate small forces with large displacements. As, up to the authors knowledge, none of the exerted efforts were concerned with investigating the possibility of using the large disassembly forces that could be generated using shape memory alloy actuators in large force active disassembly applications. Consequently, the presented research aims to examine the possibility of applying active disassembly with products requiring large disassembly forces, having tapered surfaces and large mechanical structure. By presenting two case studies to validate the possibility of using active disassembly with large force applications, in addition to investigating the capability of using shape memory alloy actuators assembled either concentric or eccentric with the product structure.

The thesis defended in this contribution to Viking studies in the British Isles is simple and straightforward. It is argued that the Viking warrior Ragnarr Loðbrók was an historical personage. Tradition associates him with the area about the Kattegat and in particular with south Norway and Zealand where Ragnarr and his sons were the leaders of a large force of vikings. These were sea-kings rather than rulers of territories. Ragnarr flourished in the first half of the ninth century and died some time after 851. Amongst his many sons, three were famous: Ívarr inn beinlausi, Hálfdan and Ubbe. Ragnarr was the leader (or one of the leaders) of the Danish attack on the Irish Vikings, probably Norwegians, in 851 and his son Ívarr established himself as king of Dublin which he ruled jointly from 853 with one Óláfr, identical with the Vestfold king, Óláfr Geirstaðaálfr, who after years of campaigning in Ireland with Ívarr returned to Norway in or about 871.

The Relationship

Impact manipulation instantaneously generates a large force making it effective for pressfitting. We model pressfitting and analyze it for realization by a robot manipulator, analyzing the relationship between hit speed and pressfitting depth to determine the hit speed required for different pressfitting depths. We use an under-actuated manipulator for hitting the “sweet spot” of the end effector, introducing a simple genetic algorithm to plan manipulator movement to generate the desired hit speed. Results of experiments on pressfitting for driving an under-actuated manipulator verified the feasibility of our proposal.
