Containerless high purity pulling process and apparatus for glass fiber

Apparatus and method for pulling optical glass fibers in a containerless environment is disclosed which includes a single axis acoustical levitation furnace in which a specimen is levitated and melted. A reflector unit is carried in the interior of the furnace and includes a reflector disposed centrally about the acoustical axis of the levitator. The reflector unit includes a circular shroud of insulation and a copper sleeve inserted in the unit which is hollow at for receiving a cooling medium. A fiber pulling bore is formed centrally in the reflector unit surrounded by cooling jacket to enhance solidification and formation of a fiber. A starting fiber strand is introduced into the melt and pulled outwardly through bore whereby the specimen fiber is started and formed as pulled therethrough. In order to replenish the melt and thus enable a continous process, a movable secondary reflector is provided which captures a supplemental specimen pellet and by movement of the reflector transfers it to the melt

Enterprise Risk Management In The Oil And Gas Industry: An Analysis Of Selected Fortune 500 Oil And Gas Companies Reaction In 2009 And 2010

In 2009, four of the top ten Fortune 500 companies were classified within the oil and gas industry. Organizations of this size typically have an advanced Enterprise Risk Management system in place to mitigate risk and to achieve their corporations\u27 objectives. The companies and the article utilize the Enterprise Risk Management Integrated Framework developed by the Committee of Sponsoring Organizations (COSO) as a guide to organize their risk management and reporting. The authors used the framework to analyze reporting years 2009 and 2010 for Fortune 500 oil and gas companies. After gathering and examining information from 2009 and 2010 annual reports, 10-K filings, and proxy statements, the article examines how the selected companies are implementing requirements identified in the previously mentioned publications. Each section examines the companies Enterprise Risk Management system, risk appetite, and any other notable information regarding risk management. One observation was the existence or non-existence of a Chief Risk Officer or other Senior Level Manager in charge of risk management. Other observations included identified risks, such as changes in economic, regulatory, and political environments in the different countries where the corporations do business. Still others identify risks, such as increases in certain costs that exceed natural inflation, volatility and instability of market conditions. Fortune 500 oil and gas companies included in this analysis are ExxonMobil, Chevron, ConocoPhillips, Baker Hughes, Valero Energy, and Frontier Oil Corporation. An analysis revealed a sophisticated understanding and reporting of many types of risks, including those associated with increasing production capacity. Specific risks identified by companies included start-up timing, operational outages, weather events, regulatory changes, geo-political and cyber security risks, among others. Mitigation efforts included portfolio management and financial strength. There is evidence that companies in later reports (2013) are more comprehensive in their risk management and reports as evidenced by their 10-K and Proxy Statements (Marathon Oil Corporation, 2013)

Containerless glass fiber processing

An acoustic levitation furnace system is described that was developed for testing the feasibility of containerless fiber pulling experiments. It is possible to levitate very dense materials such as platinum at room temperature. Levitation at elevated temperatures is much more difficult. Samples of dense heavy metal fluoride glass were levitated at 300 C. It is therefore possible that containerless fiber pulling experiments could be performed. Fiber pulling from the melt at 650 C is not possible at unit gravity but could be possible at reduced gravities. The Acoustic Levitation Furnace is described, including engineering parameters and processing information. It is illustrated that a shaped reflector greatly increases the levitation force aiding the levitation of more dense materials

User Information Risk: How It Improves Audit Quality

Audited financial statements are the basis for the communication of essential financial information.  Accordingly, the reliability of the financial statements is of extreme importance to all parties involved in the process.  This paper identifies the three primary parties as the organization, the auditor, and the user and recommends the user play an increased role in this process.  The user should be allowed to analyze the quality of the auditor and audit process based upon five critical factors that should be required to be disclosed by the auditor.  This paper discusses the five factors and how each one could benefit the user’s analysis of audit quality

Keystone XL Pipeline

The Keystone Pipeline and everything it entails has taken over the news and the majority of North America. Most people around the United States did not know the Keystone Pipeline already existed before all of the uproar and protesting began back at the end of 2011. The part of the pipeline that does not exist is the additional expansion, the Keystone XL Pipeline, which was proposed in 2008. Since the approval of the project in March 2010, the Keystone XL Pipeline has been a problematic proposition ever since the idea was introduced by the TransCanada Energy Company. While the project was originally developed as a partnership between TransCanada and ConocoPhillips, TransCanada is now the sole owner of the Keystone Pipeline System, as TransCanada received regulatory approval on August 12, 2009 to purchase ConocoPhillips' interest. TransCanada attempted to get a permit for the new pipeline for more than three years. Since the pipeline crosses international borders, TransCanada had to obtain a Presidential Permit through the State Department for construction of the portion of the pipeline that goes from Canada to the U.S. To this day, even though a substantial amount of the project is complete, protesters are still against the idea of transporting tar sands throughout Canada and the United States to refineries in Houston, Texas so that we will have additional sources of oil and fuel to supply our needs. The paper discusses the controversy, the accounting implications, the legal implications, and local press. Pictures Included

NITROGEN CARRY-OVER IMPACTS IN IRRIGATED COTTON PRODUCTION, SOUTHERN HIGH PLAINS OF TEXAS

A dynamic optimization model which introduces an intertemporal nitrate-nitrogen residual function is used to derive and evaluate nitrogen fertilizer optimal decision rules for irrigated cotton production in the Southern High Plains of Texas. Results indicate that optimal nitrogen applications critically depend on initial nitrate-nitrogen levels and nitrogen-to-cotton price ratios. Also, the results indicate that single-year optimization leads to suboptimal nitrogen applications, which helps explain long-term cotton yield declines in the Southern High Plains of Texas; but single-year optimization does not significantly impact the net present value of returns of irrigated cotton operations.Crop Production/Industries,

Environmental Risks: Doing Business in China

Planning and conducting the audit of financial statements involves understanding the entity and the environment in which it operates. First and foremost this requires identifying the risks faced by the entity. Identifying these risks can be a complex and difficult task since the auditor needs to not only understand the entity’s risk process but also independently understand the risks facing the firm. Tackling this task will involve a comprehensive review of the external and internal factors affecting the business. It is possible many identified business risks are related to financial reporting risk and ultimately to audit risk. Therefore, the auditor must understand the linkage between risks, controls and the audit. The objective of this paper is to examine the risks faced by U.S. companies conducting business in China. This paper attempts to identify a wide array of risks faced by U.S. companies to demonstrate how important it is for the company and the auditor to understand the business environment
