Commonwealth of the Northern Mariana Islands: Pending Legislation Would Apply U.S. Immigration Law to the CNMI with a Transition Period (open access)

Commonwealth of the Northern Mariana Islands: Pending Legislation Would Apply U.S. Immigration Law to the CNMI with a Transition Period

A letter report issued by the Government Accountability Office with an abstract that begins "The Commonwealth of the Northern Mariana Islands (CNMI) is subject to most U.S. laws but, under the terms of its 1976 covenant with the United States, administers its own immigration system. It has applied this flexibility to admit substantial numbers of foreign workers, in addition to admitting tourists and foreign investors. The covenant grants Congress the right to apply federal immigration law to the CNMI. On December 11, 2007, the House of Representatives passed legislation applying U.S. immigration law to the CNMI; as of report issuance, this legislation was pending in the Senate. If passed, it will amend the covenant and will apply federal immigration law to the CNMI 1 year after the legislation's enactment, subject to a transition period that begins 1 year after enactment but may be delayed 180 days. GAO was asked to review key provisions of the pending legislation, current U.S. immigration law, and current CNMI immigration law, particularly regarding (1) foreign workers, (2) tourists, and (3) foreign investors. The Departments of Homeland Security and the Interior generally agreed with the findings in this report, and the Department of Labor provided no …

EnergyPlus Analysis Capabilities for Use in California Building Energy Efficiency Standards Development and Compliance Calculations (open access)

EnergyPlus Analysis Capabilities for Use in California Building Energy Efficiency Standards Development and Compliance Calculations

California has been using DOE-2 as the main building energy analysis tool in the development of building energy efficiency standards (Title 24) and the code compliance calculations. However, DOE-2.1E is a mature program that is no longer supported by LBNL on contract to the USDOE, or by any other public or private entity. With no more significant updates in the modeling capabilities of DOE-2.1E during recent years, DOE-2.1E lacks the ability to model, with the necessary accuracy, a number of building technologies that have the potential to reduce significantly the energy consumption of buildings in California. DOE-2's legacy software code makes it difficult and time consuming to add new or enhance existing modeling features in DOE-2. Therefore the USDOE proposed to develop a new tool, EnergyPlus, which is intended to replace DOE-2 as the next generation building simulation tool. EnergyPlus inherited most of the useful features from DOE-2 and BLAST, and more significantly added new modeling capabilities far beyond DOE-2, BLAST, and other simulations tools currently available. With California's net zero energy goals for new residential buildings in 2020 and for new commercial buildings in 2030, California needs to evaluate and promote currently available best practice and emerging technologies to …

Health Insurance: Most College Students Are Covered through Employer-Sponsored Plans, and Some Colleges and States Are Taking Steps to Increase Coverage

A letter report issued by the Government Accountability Office with an abstract that begins "College students face challenges obtaining health insurance--they may not have access to insurance through an employer, and as they get older, they may lose dependent coverage obtained through a parent's plan. Federal law ensures continued access to health insurance for some, but not all, such students. Without health insurance, college students may be unable to pay for their health care, and the cost of this care may be passed on to federal and state payers, such as Medicaid. College students may have access to student insurance plans offered by their colleges. GAO was asked to report on uninsured college students, student insurance plans, and efforts to increase the number of insured students. GAO reviewed (1) college students' insurance status, (2) uninsured college students' characteristics, (3) the extent to which colleges offered student insurance plans and the characteristics of available plans, and (4) efforts to increase the number of insured students. GAO analyzed data from a national survey on college students' insurance status and uninsured college students' characteristics. GAO collected data from 340 colleges on the availability of student insurance plans and the characteristics of available plans, …

HYDROGEN EFFECTS ON THE FRACTURE TOUGHNESS PROPERTIES OF FORGED STAINLESS STEELS (open access)

HYDROGEN EFFECTS ON THE FRACTURE TOUGHNESS PROPERTIES OF FORGED STAINLESS STEELS

The effect of hydrogen on the fracture toughness properties of Types 304L, 316L and 21-6-9 forged stainless steels was investigated. Fracture toughness samples were fabricated from forward-extruded forgings. Samples were uniformly saturated with hydrogen after exposure to hydrogen gas at 34 MPa or 69 and 623 K prior to testing. The fracture toughness properties were characterized by measuring the J-R behavior at ambient temperature in air. The results show that the hydrogen-charged steels have fracture toughness values that were about 50-60% of the values measured for the unexposed steels. The reduction in fracture toughness was accompanied by a change in fracture appearance. Both uncharged and hydrogen-charged samples failed by microvoid nucleation and coalescence, but the fracture surfaces of the hydrogen-charged steels had smaller microvoids. Type 316L stainless steel had the highest fracture toughness properties and the greatest resistance to hydrogen degradation.

In Situ Microbial Community Control of the Stability of Bio-reduced Uranium (open access)

In Situ Microbial Community Control of the Stability of Bio-reduced Uranium

In aerobic aquifers typical of many Department of Energy (DOE) legacy waste sites, uranium is present in the oxidized U(VI) form which is more soluble and thus more mobile. Field experiments at the Old Rifle UMTRA site have demonstrated that biostimulation by electron donor addition (acetate) promotes biological U(VI) reduction (2). However, U(VI) reduction is reversible and oxidative dissolution of precipitated U(IV) after the cessation of electron donor addition remains a critical issue for the application of biostimulation as a treatment technology. Despite the potential for oxidative dissolution, field experiments at the Old Rifle site have shown that rapid reoxidation of bio-reduced uranium does not occur and U(VI) concentrations can remain at approximately 20% of background levels for more than one year. The extent of post-amendment U(VI) removal and the maintenance of bioreduced uranium may result from many factors including U(VI) sorption to iron-containing mineral phases, generation of H2S or FeS0.9, or the preferential sorption of U(VI) by microbial cells or biopolymers, but the processes controlling the reduction and in situ reoxidation rates are not known. To investigate the role of microbial community composition in the maintenance of bioreduced uranium, in-well sediment incubators (ISIs) were developed allowing field deployment of …

Influence of Time-Dependent Factors in the Evaluation of Critical Infrastructure Protection Measures. (open access)

Influence of Time-Dependent Factors in the Evaluation of Critical Infrastructure Protection Measures.

The examination of which protective measures are the most appropriate to be implemented in order to prevent, protect against, respond to, and recover from attacks on critical infrastructures and key resources typically involves a comparison of the consequences that could occur when the protective measure is implemented to those that could occur when it is not. This report describes a framework for evaluation that provides some additional capabilities for comparing optional protective measures. It illustrates some potentially important time-dependent factors, such as the implementation rate, that affect the relative pros and cons associated with widespread implementation of protective measures. It presents example results from the use of protective measures, such as detectors and pretrained responders, for an illustrative biological incident. Results show that the choice of an alternative measure can depend on whether or not policy and financial support can be maintained for extended periods of time. Choice of a time horizon greatly influences the comparison of alternatives.

Restoration of Weak Phase-Contrast Images Recorded With a High Degree of Defocus: The "Twin Image" Problem Associated With CTF Correction (open access)

Restoration of Weak Phase-Contrast Images Recorded With a High Degree of Defocus: The "Twin Image" Problem Associated With CTF Correction

Relatively large values of objective-lens defocus must normally be used to produce detectable levels of image contrast for unstained biological specimens, which are generally weak phase objects. As a result, a subsequent restoration operation must be used to correct for oscillations in the contrast transfer function (CTF) at higher resolution. Currently used methods of CTF-correction assume the ideal case in which Friedel mates in the scattered wave have contributed pairs of Fourier components that overlap with one another in the image plane. This"ideal" situation may be only poorly satisfied, or not satisfied at all, as the particle size gets smaller, the defocus value gets larger, and the resolution gets higher. We have therefore investigated whether currently used methods of CTF correction are also effective in restoring the single-sideband image information that becomes displaced (delocalized) by half (or more) the diameter of a particle of finite size. Computer simulations are used to show that restoration either by"phase flipping" or by multiplying by the CTF recovers only about half of the delocalized information. The other half of the delocalized information goes into a doubly defocused"twin" image of the type produced during optical reconstruction of an in-line hologram. Restoration with a Wiener filter …
