Accidental oil spills from crude oil tankers have resulted in large changes in the tanker industry. New international regulations have been issued and a large variety of environmental tanker design concepts has been developed to reduce accidental outflow.
A systematic analysis of these concepts results in a number of practical principles of outflow reduction. For instance after tank penetration a large portion of the cargo can be kept inside the tank by simple principles; the author has added a new concept in this area: the so-called ECO-Bulkhead. In this dissertation the various principles are combined effectively into one single design methodology, which helps to improve existing tanker concepts and to develop new ones.
Their performance is compared to that of a base double hull BDH design. Further a mid-deck MD design concept is added as a representative of alternative designs. The main differences are found inside the tank region and are related to the different arrangement of cargo and ballast tanks and internal bulkheads.
This result is more remarkable as the building costs of the COBO are lower. The appendices are published in a separate publication. The versatility of Biomechanics with the use of "smart wires" allows different strategies in order to achieve a better control in orthodontic cases.
Since the force system, along with the side effects, of theses wires is well understood it becomes easier to use noncompliance mechanics. The present paper showed the clinical applications of the "smart wires" nickel-titanium intrusion arch and M-loop archwires capable of simultaneously performing different orthodontic movements in extraction cases which minimize the need for high anchorage control.
Bone anchorage : When and why? Anchorage is the most important concept in biomechanics of orthodontics. In contemporary orthodontics, bone anchorage is a magic tool, which decreased the indication for extraoral appliances greatly and at the same time achieving stationary anchorage became possible.
However, the indication for bone anchorage has to be clarified carefully. Skeletal open-bite treatment, effective molar distalization, Class III treatment by using chin anchorage , and space closure in severe minimal anchorage cas Full Text Available Anchorage is the most important concept in biomechanics of orthodontics.
Skeletal open-bite treatment, effective molar distalization, Class III treatment by using chin anchorage , and space closure in severe minimal anchorage cases are some examples for bone anchorage supported orthodontic treatment. Here, we discussed three necessary usages of bone anchorage for different treatment modalities.
Transport of liquefied natural gas by tankers. Leachate storage transport tanker loadout piping. This report contains schematic drawings for the pipe fittings for the Hanford waste tanks. Included are the modifications to the W trench number-sign 31 leachate loadout piping, and also the modifications to the tanker trailers. The piping was modified to prevent spillage to the environment. The tankers were modified for loading and unloading purposes.
These areas were to be collected to the 'highest' accuracy requirement. Ground Control is collected throughout the AOI for Because of its vast photovoltaic experience, BDM was chosen over several engineering firms to perform this complex job. We were provided a conceptual design from ARCO which we quickly refined and immediately initiated construction. Arco Chimie France Fos-sur-Mer , at a recent meeting at its southern France manufacturing site, emphasized that future strategy is strongly focused on its propylene oxide PO and derivatives activities.
The F2. The company would also require investment in new storage capacity for ethanol and ETBE. However, France's biofuels program is not yet clearly defined, and it is politically sensitive because it depends heavily on government subsidies offered to farmers.
That, says Arco , makes it impossible to have an accurate idea of how much ethanol will be available. The liquefied natural gas infrastructure and tanker fleet sizing problem. We consider a strategic infrastructure and tanker fleet sizing problem in the liquefied natural gas business.
The goal is to minimize long-term on-shore infrastructure and tanker investment cost combined with interrelated expected cost for operating the tanker fleet.
A non-linear arc-based model ARCO Chairman forecasts end of oil dominance. The head of one of the world's biggest oil companies said in February that the era of oil dominating the global energy market is creaking to a close. Future energy needs will be met by a mix of fuels that are less harmful to the environment, he said, and he called for the energy and automobile industries to collaborate on solutions to reduce emissions. ARCO 's return on capital employed for the past 6 years has been an industry-leading However, even ARCO has not been immune to the severe problems of the domestic oil and gas business, and ARCO believes these domestic problems are not likely to disappear quickly.
ARCO 's response has been twofold: a careful revamping of the domestic exploration and production arm; and thoughtful expansion of ARCO 's international efforts. In the late 's ARCO 's senior management concluded that oil reserves and corporate profit from exploration and production E and P could be most successfully increased by a larger presence in international investments.
It was recognized that success would not come from merely pouring more money into international E and P but would require structural changes in operations and enhanced risk management.
Implants for orthodontic anchorage. Abstract Implantanchorage continues to receive much attention as an important orthodontic anchorage. Since the development of orthodontic implants, the scope of applications has continued to increase. Although multiple reviews detailing implants have been published, no comprehensive evaluations have been performed.
Thus, the purpose of this study was to comprehensively evaluate the effects of implants based on data published in review articles. A subsequent manual search was then performed to identify reviews concerning orthodontic implants. Such systematic reviews that evaluated the efficacy and safety of orthodontic implants were used to indicate success rates and molar movements.
A total of 23 reviews were included in the analysis. Most reviews were less than moderate quality. Success rates of implants ranged in a broad scope, and movement of the maxillary first molar was superior with implants compared with traditional anchorage. Tanker spills Norwegian crude oil off Shetlands. This paper reports that crude oil was spilling last week from the U. Workers were trying to assess the extent of damage to the tanker , shoreline, and wildlife after the January 5 accident.
Braer's cargo amounted to , bbl of Norwegian oil bound for Canada. Romuald, Que. Tanker traffic off Newfoundland worries fishermen. Tanker traffic offshore in Placentia Bay, Newfoundland has increased considerably, where approximately tankers show up yearly to load up at the oil refinery located in the nearby village of Come By Chance. On numerous occasions, fishermen busy pulling gear over the gunwales looked up only to be faced with an approaching superstructure just emerging from the fog, leaving barely enough time for the fishermen to get out of the way.
Fog does not help the situation, often reducing visibility to less than one kilometre approximately days yearly. Fishermen are reluctant to avoid shipping lanes, as some of the best grounds are located in the vicinity.
A few close calls and one accident were briefly described. Requests have been made for the pilots bringing large ships into dock to board farther out at sea to avoid the danger of collision. It was mentioned that another factor could be crew members on some ships unable to speak English. Fishermen are not happy that results from ship inspections are not posted on the Web as is the case in the United States.
An environmentalist has also requested that an ocean-going-tug be used for towing tankers in trouble out of the way to prevent an ecological disaster. Corrosion testing on crude oil tankers and other product carriers by means of acoustic emission AE.
In the last decades a lot of maritime disasters with crude oil tankers occurred e. Exxon- Valdez, Erika, Prestige. Every accident led to extreme pollution with horrible consequences not only for the environment but also for the life of the inhabitants of the affected coasts. Although most of these accidents were caused by human errors, the material degradation of the ship hull due to corrosion played an important role.
Acoustic emission AE is already used to detect and discriminate the stage of corrosion of structures located on land. A consortium consisting of experienced partners from the fields of ship building and classification as well as from AE testing and equipment manufacturing started to investigate the feasibility of this testing technique for its application on oil tankers. The aim of the research project funded by the European Commission is to develop an on-line corrosion monitoring technique based on a permanent installation of AE sensors as well as a spot testing technique during stops in harbors or at anchorages using mobile equipment.
Since the project was started, a lot of lab tests as well as background measurements were done on different types of tankers up to a size of The gathered data were evaluated with a frequency domain based pattern recognition system and it was possible to distinguish the AE signals related to corrosion from those signals, which were emitted by the structure due to the harsh environment on sea background noise.
Together with the oncoming developments of the AE equipment and the improvement of the data base, this project will lead to an important breakthrough for the safe shipping of hazardous products like crude oil. ARCO moves to spark U.
This paper reports that one US major oil company has taken the offensive to combat tightness of drilling capital in the US and the overseas flight of interest in elephant hunting. ARCO is looking to bring others in on its prospects, hawk seismic data, and take deals from others. Friction and anchorage loading revisited. Contemporary concepts of sliding mechanics explain that friction is inevitable.
To overcome this frictional resistance, excess force is required to retract the tooth along the archwire ie, individual retraction of canines, en masse retraction of anterior teeth , in addition to the amount of force required for tooth movement. The anterior tooth retraction force, in addition to excess force to overcome friction , produces reciprocal protraction force on molars, thereby leading to increased anchorage loading.
