A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) and selected components are implementing strategies to fill mission-critical occupations (MCO), which are those occupations most critical to an agency's mission. In 2011, the Office of Diversity and Inclusion (D&I)--which coordinates component recruiting efforts--developed the Coordinated Recruiting and Outreach Strategy (CROS). Through the CROS, D&I intends to better coordinate and link component recruiting and outreach efforts to hiring for DHS mission and workforce needs (for all positions, including MCOs), and to leverage resources as well as reduce recruiting costs, among other things. D&I has begun to implement the CROS through various means, including requiring components to develop their own outreach and recruiting plans that align with the CROS. However, D&I has been limited in its ability to implement some elements of the CROS--such as recruiter training--because of budget constraints, according to D&I officials. The components selected for GAO's review--the National Protection and Programs Directorate, Transportation Security Administration (TSA), U.S. Citizenship and Immigration Services, and U.S. Secret Service (USSS)--have also implemented various strategies to recruit and hire MCOs. In addition, these four components have generally been able to address hiring needs …

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Agency for International Development (USAID) has made progress in coordinating with U.S. partner agencies through the whole-of-government approach for the Feed the Future (FTF) initiative that began in 2010. According to USAID documents, this approach involves coordination and integration of expertise and resources across U.S. partner agencies with global food security programs. In reports issued in 2008 and 2010, GAO found that U.S. agency food security efforts were fragmented and uncoordinated. Under FTF, GAO found that USAID leads the whole-of-government approach by better coordinating and integrating partner agencies' knowledge and expertise at three levels: at headquarters in Washington, D.C.; in each of the 19 FTF focus countries; and between the countries and headquarters. In headquarters, USAID and FTF partner agencies established joint strategies and new data management systems to track funding and results across the U.S. government. At the country level, in GAO's survey of U.S. FTF partner agency representatives in 19 FTF focus countries, 93 percent reported coordinating with USAID."

A letter report issued by the Government Accountability Office with an abstract that begins "Several of the Department of Homeland Security's (DHS) Federal Protective Service's (FPS) guard requirements are generally comparable to those of the six selected agencies GAO reviewed, but FPS faces challenges in some aspects of guards' training. FPS and the six selected agencies GAO reviewed require basic, firearms, and screener (x-ray and magnetometer equipment) training for their armed guards. However, GAO found that providing screener training remains a challenge for FPS. For example, officials from one of FPS's contract guard companies stated that 133 (about 38 percent) of its approximately 350 guards have never received this training. Similarly, according to officials at five guard companies, some of their contract guards have not received training on how to respond during incidents involving an active shooter. Additionally, while contract guard industry guidance states that all training should be done with a certified instructor, GAO found that FPS does not require guard instructors to be certified to provide basic and refresher training, which represents the majority of guards' training. According to six guard companies, the lack of a requirement has led to having to retrain some guards, potentially increasing costs …

Compaction of lower layers in the fiberboard assembly has been observed in 9975 packages that contain elevated moisture. Lab testing has resulted in a better understanding of the relationship between the fiberboard moisture level and compaction of the lower fiberboard assembly, and the behavior of the fiberboard during transport. In laboratory tests of cane fiberboard, higher moisture content has been shown to correspond to higher total compaction, greater rate of compaction, and continued compaction over a longer period of time. In addition, laboratory tests have shown that the application of a dynamic load results in higher fiberboard compaction compared to a static load. The test conditions and sample geometric/loading configurations were chosen to simulate the regulatory requirements for 9975 package input dynamic loading. Dynamic testing was conducted to acquire immediate and cumulative changes in geometric data for various moisture levels. Two sample sets have undergone a complete dynamic test regimen, one set for 27 weeks, and the second set for 47 weeks. The dynamic input, data acquisition, test effects on sample dynamic parameters, and results from this test program are summarized and compared to regulatory specifications for dynamic loading. Compaction of the bottom fiberboard layers due to the accumulation of …

This project seeks to determine if inorganic or hybrid inorganic ion-exchange materials can be exploited to provide effective americium and curium separations. Specifically, we seek to understand the fundamental structural and chemical factors responsible for the selectivity of the tested ion-exchange materials for actinide and lanthanide ions. During FY13, experimental work focused in the following areas: (1) investigating methods to oxidize americium in dilute nitric acid with subsequent ion-exchange performance measurements of ion exchangers with the oxidized americium and (2) synthesis, characterization and testing of ion-exchange materials. Ion-exchange materials tested included alkali titanates, alkali titanosilicates, carbon nanotubes and group(IV) metal phosphonates. Americium oxidation testing sought to determine the influence that other redox active components may have on the oxidation of Am(III). Experimental findings indicated that Pu(IV) is oxidized to Pu(VI) by peroxydisulfate, but there are no indications that the presence of plutonium affects the rate or extent of americium oxidation at the concentrations of peroxydisulfate being used. Tests also explored the influence of nitrite on the oxidation of Am(III). Given the formation of Am(V) and Am(VI) in the presence of nitrite, it appears that nitrite is not a strong deterrent to the oxidation of Am(III), but may be limiting Am(VI) …

Synopsis: Light loss factors are used to help lighting systems meet quantitative design criteria throughout the life of the installation, but they also influence energy use. As the light sources currently being specified continue to evolve, it is necessary to reevaluate the methods used in calculating light loss factors, as well as carefully consider the consequences of different product performance attributes. Because of the unique operating characteristics of LEDs and lack of a comprehensive lifetime rating—as well as the problematic relationship between lifetime and lumen maintenance—determining an appropriate lamp lumen depreciation (LLD) factor for LED products is difficult. As a result, a unique solution has been advocated: when quantity of light is an important design consideration, the IES recommends using an LLD of not greater than 0.70. This method deviates from the typical practice for conventional sources of using the ratio of mean to initial lumen output, and can misrepresent actual performance, increase energy use, and inhibit comparisons between products. This paper discusses the complications related to LLD and LEDs, compares the performance of conventional and LED products, and examines alternatives to a maximum LLD of 0.70 for LEDs.

A low temperature waste form known as Cast Stone is being considered to provide supplemental Low Activity Waste (LAW) immobilization capacity for the Hanford site. Formulation of Cast Stone at high sodium concentrations is of interest since a significant reduction in the necessary volume of Cast Stone and subsequent disposal costs could be achieved if an acceptable waste form can be produced with a high sodium molarity salt solution combined with a high water to premix (or dry blend) ratio. The objectives of this study were to evaluate the factors involved with increasing the sodium concentration in Cast Stone, including production and performance properties and the retention and release of specific components of interest. Three factors were identified for the experimental matrix: the concentration of sodium in the simulated salt solution, the water to premix ratio, and the blast furnace slag portion of the premix. The salt solution simulants used in this study were formulated to represent the overall average waste composition. The cement, blast furnace slag, and fly ash were sourced from a supplier in the Hanford area in order to be representative. The test mixes were prepared in the laboratory and fresh properties were measured. Fresh density increased …

We performed a systematic microscopic investigation of two completely dissimilar materials (namely, ZnO and rhombohedral-C{sub 60} polymers) exhibiting ferromagnetism in the presence of defects, and showed that this new phenomena has a common origin and the mechanism responsible can be used as a powerful tool for inducing and tailoring magnetic features in systems which are not magnetic otherwise. Based on our findings we proposed a general recipe for developing ferromagnetism in new materials of great technological interest. Our results support the role of complimentary pairs of defects in inducing magnetism in otherwise non-magnetic materials belonging to two widely differing classes with no apparent correlation between them. In both classes, ferromagnetism is found to be enhanced when the two kinds of defects form structures (pathways) of alternating effective donor and acceptor crystal sites leading to the development of electron charge and spin density like waves. Using ab initio density functional theory calculations we predicted the existence of a new class of carbon cages formed via hybrid connection between planar graphene sheets and carbon nanotubes. The resulting novel structure has the appearance of ?nano-drum? and offers the exciting prospect of integrating useful device properties of both graphene as well as the nanotube …
