Needs assessment for the Greenway Grand Forks-East Grand Forks development and public education  

NASA Astrophysics Data System (ADS)

Following the flood of 1997, the U.S. Army Corps of Engineers included the Greenway Grand Forks---East Grand Forks (the Greenway) as a flood control measure for Grand Forks, North Dakota and East Grand Forks, Minnesota. It extends along both the Red River of the North and the Red Lake River, encompassing 2200 acres of land. The cities of Grand Forks and East Grand Forks hired consultants to assist with the postflood planning process. The planning process culminated with the Red River of the North Greenway Final Report (Flink, 1998). The purpose of this study was to determine if the development of the Greenway addressed the objectives of the planning report. The history of the land adjacent to the rivers was reviewed to document the progression of riverfront development. Anecdotal evidence was collected, field observations were made, city council minutes were reviewed, Greenway Technical Committee members were interviewed, Greenway Technical Committee minutes were reviewed, and the Greenway Grand Forks---East Grand Forks survey results were reviewed to determine if the objectives of the Red River of the North Greenway Final Report were addressed. A cross section survey was designed by Laura Munski for this dissertation research. The survey was approved by the Greenway Technical Committee. The survey collected both quantitative and qualitative data from the community. The purpose of the survey portion of the research project was to ascertain how residents were kept informed of activities on the Greenway and what amenities residents were using on the Greenway and to solicit their comments regarding the Greenway. The results of the survey research were used in both marketing and event planning for the Greenway. The singular qualitative survey question gave respondents an opportunity to share their comments regarding the Greenway. The qualitative data analysis provided insight to the amenities and educational programs desired by respondents, their concerns regarding the Greenway, and the limitations of public knowledge regarding the Greenway. The Red River of the North Greenway Final Report (Flink, 1998) stated that the Greenway could be an excellent resource for supplementing educational curriculums. Greenways provide outdoor classrooms for both formal and informal education. The educational opportunities of other North American greenways were investigated and compared to the educational opportunities of the Greenway.

Grand Forks - East Grand Forks Urban Water Resources Study. Energy conservation and recreation appendix, public involvement appendix. Final report  

SciTech Connect

The goal of the Corps of Engineers Urban Study Program is to provide planning assistance to local interests in a variety of water resource areas. The St. Paul District conducted the Grand Forks-East Grand Forks (GF/EGF) Urban Water Resources Study which was a cooperative effort among local, state and federal agencies. Primary attention was given to flood control, water supply and wastewater management; supporting investigations addressed recreation and energy conservation. The recreation investigation consists of the leisure time analysis conducted in stage 2 of the urban study by the Heritage Conservation and Recreation Service, Department of the Interior. The leisure time analysis compared the study area's recreational needs to the available and planned facilities and identified unsatisfied needs. The thermography investigation was conducted in spring 1978 in response to the public's growing awareness of energy conservation and the Corps' desire to make the public aware of the urban study in a meaningful, useful fashion. The investigation consisted of aerial infrared photography, public displays of photographs, and distribution of information on energy saving practices. This investigation was a one-time effort with no plans for follow-up.

Groundwater and climate change: a sensitivity analysis for the Grand Forks aquifer, southern British Columbia, Canada  

NASA Astrophysics Data System (ADS)

The Grand Forks aquifer, located in south-central British Columbia, Canada was used as a case study area for modeling the sensitivity of an aquifer to changes in recharge and river stage consistent with projected climate-change scenarios for the region. Results suggest that variations in recharge to the aquifer under the different climate-change scenarios, modeled under steady-state conditions, have a much smaller impact on the groundwater system than changes in river-stage elevation of the Kettle and Granby Rivers, which flow through the valley. All simulations showed relatively small changes in the overall configuration of the water table and general direction of groundwater flow. High-recharge and low-recharge simulations resulted in approximately a +0.05 m increase and a -0.025 m decrease, respectively, in water-table elevations throughout the aquifer. Simulated changes in river-stage elevation, to reflect higher-than-peak-flow levels (by 20 and 50%), resulted in average changes in the water-table elevation of 2.72 and 3.45 m, respectively. Simulated changes in river-stage elevation, to reflect lower-than-baseflow levels (by 20 and 50%), resulted in average changes in the water-table elevation of -0.48 and -2.10 m, respectively. Current observed water-table elevations in the valley are consistent with an average river-stage elevation (between current baseflow and peak-flow stages). L'aquifère de Grand Forks, situé en Colombie britannique (Canada), a été utilisé comme zone d'étude pour modéliser la sensibilité d'un aquifère à des modifications de la recharge et du niveau de la rivière, correspondant à des scénarios envisagés de changement climatique dans cette région. Les résultats font apparaître que les variations de recharge de l'aquifère pour différents scénarios de changement climatique, modélisées pour des conditions de régime permanent, ont un impact sur le système aquifère beaucoup plus faible que les changements du niveau des rivières Kettle et Granby, qui coulent dans la vallée. Toutes les simulations ont montré des différences relativement faibles dans la configuration d'ensemble de la nappe et dans la direction générale des écoulements. Des simulations de conditions de recharge forte et de recharge faible produisent respectivement une remontée de 0,05 m et un abaissement de 0,025 m, approximativement, des cotes de la nappe pour l'ensemble de l'aquifère. Des changements simulés de la cote du niveau de la rivière, pour refléter des niveaux plus hauts que ceux des pics de crues (de 20 et de 50%), produisent respectivement des remontées de la nappe de 2,72 et 3,45 m en moyenne. Des changements simulés de l'altitude du niveau de la rivière, pour refléter des niveaux plus bas que ceux de basses eaux (de 20 et de 50%), produisent respectivement des abaissements de la nappe de 0,48 et 2,10 m en moyenne. Les altitudes courantes observées de la nappe dans la vallée sont cohérentes avec une cote moyenne du niveau de la rivière (entre les niveaux courants de basses eaux et de crues). El acuífero de los Grand Forks, situado al sur de la Columbia Británica central (Canadá) ha sido utilizado como lugar de estudio para modelar la sensibilidad de un acuífero a los cambios en la recarga y el caudal de los ríos de acuerdo con escenarios previstos de cambio climático en la región. Los resultados sugieren que las variaciones en la recarga al acuífero bajo los diversos escenarios, que han sido modelados en régimen estacionario, tienen un impacto mucho menor en las aguas subterráneas que los cambios en el caudal de los ríos Kettle y Granby, que discurren por el valle. Todas las simulaciones muestran diferencias relativamente pequeñas en la configuración regional de los niveles freáticos y en la dirección general del flujo subterráneo. Las simulaciones de recarga elevada y baja causan un incremento de 0,05 m y un decremento de 0,025 m, respectivamente, en los niveles del acuífero.

Analysis of the results of hydraulic-fracture stimulation of two crystalline bedrock boreholes, Grand Portage, Minnesota  

USGS Publications Warehouse

Hydraulic fracture-stimulation procedures typical of those provided by contractors in the water-well industry were applied to two boreholes in basaltic and gabbroic rocks near Grand Portage, Minnesota.These boreholes were considered incapable of supplying adequate ground water for even a single household although geophysical logs showed both boreholes were intersected by many apparently permeable fractures. Tests made before and after stimulation indicated that the two boreholes would produce about 0.05 and 0.25 gallon per minute before stimulation, and about 1.5 and 1.2 gallons per minute after stimulation. These increases would be enough to obtain adequate domestic water supplies from the two boreholes but would not furnish enough water for more than a single household from either borehole. Profiles of high-resolution flow made during pumping after stimulation indicated that the stimulation enhanced previously small inflows or stimulated new inflow from seven fractures or fracture zones in one borehole and from six fractures or fracture zones in the other.Geophysical logs obtained after stimulation showed no specific changes in these 13 fractures that could be related to stimulation other than the increases in flow indicated by the flowmeter logs. The results indicate that the stimulation has increased inflow to the two boreholes by improving the connectivity of favorably orientated fractures with larger scale flow zones in the surrounding rocks. Three of four possible diagnostics related to measured pressure and flow during the stimulation treatments were weakly correlated with the increases in production associated with each treatment interval. These correlations are not statistically significant on the basis of the limited sample of 16 treatment intervals in two boreholes, but the results indicate that significant correlations might be established from a much larger data set.

U-Pb geochronological constraints on the timing of episodic regional metamorphism and rapid high-T exhumation of the Grand Forks complex, British Columbia  

NASA Astrophysics Data System (ADS)

The Grand Forks complex (GFC) is a fault-bounded metamorphic core complex in the southern Omineca Belt of British Columbia, Canada. It experienced prograde metamorphism ranging from upper-amphibolite to granulite facies conditions during the Mesozoic to early Tertiary compressional stage of the Cordilleran orogeny. Peak metamorphism was followed by multi-stage exhumation in the Early Eocene. This study provides U-Pb monazite and zircon constraints on the timing of metamorphic episodes in the GFC and subsequent high-T, amphibolite facies decompression in the Early Eocene. Monazite LA-ICP-MS ages from metapelitic gneisses record episodic metamorphism from the Late Jurassic to Paleocene, with peak metamorphism occurring between ~ 59 and 50 Ma. Peak metamorphism was followed by rapid, near-isothermal decompression of the GFC between ~ 52 and 50 Ma, and leucosome crystallization at ~ 50 Ma. Thermodynamic modeling of metapelites in the system MnNCKFMASHPYCe predicts that monazite was not stable at peak metamorphic conditions, consistent with the dominant population of ~ 59 Ma ages representing growth along the prograde path, most likely at subsolidus conditions. Growth of widespread high-Y monazite rims (~ 50 Ma) is predicted along suprasolidus decompression and cooling paths. Zircon SHRIMP ages from igneous bodies in the GFC and hanging wall of the bounding Kettle River fault (KRF) suggest ductile deformation related to high-T decompression of the GFC was ongoing at 51 Ma but had ceased by 50 Ma, truncated by post-kinematic granitoids. This high-T deformation predates subsequent greenschist facies extension on the overlying KRF. A pre-KRF, hanging wall ductile shear zone is constrained to ~ 59-51 Ma. It deforms 59 Ma Ladybird suite leucogranites and may be related to high-T exhumation of the core complex. Rapid, > 100 °C/Ma cooling rates are required to accommodate high-T (amphibolite facies) exhumation of the GFC at 52-50 Ma followed by low-T (greenschist facies) exhumation at ~ 49 Ma.

Water quality (2000-08) and historical phosphorus concentrations from paleolimnological studies of Swamp and Speckled Trout Lakes, Grand Portage Reservation, northeastern Minnesota  

USGS Publications Warehouse

A paleolimnological approach was taken to aid the Grand Portage Reservation, in northeastern Minnesota, in determining reference conditions for lakes on the reservation. The U.S. Geological Survey, in cooperation with the Grand Portage Band of Chippewa Indians and the Science Museum of Minnesota, conducted a study to describe water quality (2000-08) and historical total phosphorus concentrations (approximately 1781-2006) for Swamp and Speckled Trout Lakes. Results from this study may be used as a guide in establishing nutrient criteria in these and other lakes on the Grand Portage Reservation. Historical phosphorus concentrations were inferred through paleolimnological reconstruction methods involving diatom analysis and lead-210 dating of lake-sediment cores. Historical diatom-inferred total phosphorus concentrations in Swamp Lake ranged from 0.017 to 0.025 milligrams per liter (mg/L) based on diatom assemblages in sediment samples dated 1781-2005. Historical diatom-inferred total phosphorus concentrations in Speckled Trout Lake ranged from 0.008 to 0.014 mg/L based on diatom assemblages in sediment samples dated 1825-2006. In both lakes, historical changes in diatom-inferred total phosphorus concentrations did not exceed model error estimates, indicating that there has been minimal change in total phosphorus concentrations in the two lakes over about two centuries. Nutrient concentrations in monthly water samples collected May through October during 2000, 2002, 2004, 2006, and 2008 were compared to the diatom-inferred total phosphorus concentrations. Total phosphorus concentrations from water samples collected from Swamp Lake during 2000-08 ranged from less than 0.002 to 0.160 mg/L (median= 0.023 mg/L) compared to diatom-inferred total phosphorus concentrations of 0.018 to 0.020 mg/L for 2002 to 2005. Total phosphorus concentrations in water samples collected from Speckled Trout Lake during 2000-08 were similar to those of Swamp Lake, ranging from less than 0.002 to 0.147 mg/L (median=0.012 mg/L), whereas the diatom-inferred total phosphorus concentrations were smaller, ranging from 0.009 to 0.010 mg/L for 2003 to 2006. Differences in total phosphorus concentrations between the two lakes may be because of differences in watershed characteristics, particularly the number of wetlands in the two watersheds. Similarities between recent total phosphorus concentrations in water-quality samples and diatom-inferred total phosphorus indicate that diatom-inferred phosphorus reconstructions might be used to help establish reference conditions. Nutrient criteria for Grand Portage Reservation lakes may be established when a sampling program is designed to ensure representative phosphorus concentrations in water samples are comparable to diatom-inferred concentrations.

Simulated effects of water-level changes in the Mississippi River and Pokegama Reservoir on ground-water levels, Grand Rapids area, Minnesota  

USGS Publications Warehouse

The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, used an existing, three-dimensional, numerical ground-water flow model (referred to as the calibrated model) to assess the effects of water-level changes in the Mississippi River and Pokegama Reservoir on ground-water levels in adjacent glaciofluvial aquifers in the Grand Rapids area of north-central Minnesota. Pokegama Reservoir consists of Pokegama Lake, Little Jay Gould Lake, Jay Gould Lake, Cut-off Lake, and Blackwater Lake. Water levels in the Pokegama Reservoir are regulated at Pokegama Dam on the Mississippi River west of Grand Rapids. A steady-state model was used, and simulations represent 'worse-case' scenarios for the effects of lowering or raising the river and lake water levels. The simulated ground-water levels represent levels that would result if the river and lake stages permanently declined or rose by the specified amounts. Eight hypothetical scenarios were simulated by varying water levels in the Mississippi River and Pokegama Reservoir from values used in the calibrated model. In the simulations, water levels for the Mississippi River, riverine wetlands of the Mississippi River, and lakes of the Pokegama Reservoir were raised and lowered uniformly by 0.50, 1.00, 2.00, and 3.00 feet from calibrated water levels. The extent of aquifer water-level changes resulting from these river, wetland, and lake water-level changes varied because of the complex hydrogeology of the study area. A 1.00-foot decline in reservoir/river water levels caused a maximum simulated ground-water-level decline in the middle aquifer near Jay Gould and Little Jay Gould Lakes of 1.09 feet and a maximum simulated ground-water-level decline of 1.00 foot in the lower aquifer near Cut-off and Blackwater Lakes. The amount and extent of ground-water-level changes in the middle and lower aquifers can be explained by the thickness, extent, and connectivity of the aquifers. Surface-water/ground-water interactions near wetlands and lakes with water levels unchanged from the calibrated model resulted in small water-table altitude differences among the simulations. Results of the ground-water modeling indicate that lowering of the reservoir and river water levels by 1.00 foot likely will not substantially affect water levels in the middle and lower aquifers.

Estimation of Monthly Evaporation from Lake Ashtabula in North Dakota, Orwell Lake in Minnesota, and Lake Traverse in Minnesota and South Dakota, 1931-2001  

USGS Publications Warehouse

Reservoirs on tributaries of the Red River of the North provide water for Fargo and Grand Forks, N. Dak., and other cities along the river. Adequate estimates of evaporative losses from the reservoirs are needed to determine the total water supply in the Basin. Many equations could be used to estimate lake or reservoir evaporation. However, in addition to measurements of air temperature, the equations require measurements of net radiation, wind speed, and relative humidity. Evaporation and air temperature data from energy budget evaporation sites at Wetland P1 in North Dakota and at Williams Lake in Minnesota are available. Air temperature data collected from climate stations near Lake Ashtabula in North Dakota, from Orwell Lake in Minnesota, and from Lake Traverse in Minnesota and South Dakota also are available. Therefore, the combined data sets were used to estimate monthly evaporation from Lake Ashtabula, Orwell Lake, and Lake Traverse. Averaged monthly mean air temperatures determined for each reservoir study site were used to calculate monthly evaporation data sets for 1931-2001. Results from the procedure that estimates reservoir evaporation indicate that slight downward trends in annual evaporation occurred from 1931-2001. The trends may have been caused by the selected time period of the study, which began with the drought conditions in the mid 1930's and ended with the more wet conditions in the late 1990's. Average annual evaporation values for each reservoir for 1931-2001 correspond well with published average annual lake evaporation values for 1946-55.

After learning that water flows down a slope, students will understand that this concept determines how our watersheds flow. It will also explain why some rivers (such as the Red River) appear to be flowing "up" on a map. They will then create a landform map of Minnesota accurately representing the higher elevations (our RIDGELINES) and the location of our major rivers and bodies of water.

Avoiding chromosome pathology when replication forks collide  

PubMed Central

Chromosome duplication normally initiates via the assembly of replication fork complexes at defined origins1,2. DNA synthesis by any one fork is thought to cease when it meets another travelling in the opposite direction, at which stage the replication machinery may simply dissociate before the nascent strands are finally ligated. But what actually happens is not clear. Here we present evidence consistent with the idea that every fork collision has the potential to threaten genomic integrity. In Escherichia coli this threat is kept at bay by RecG DNA translocase3 and by single-strand DNA exonucleases. Without RecG, replication initiates where forks meet via a replisome assembly mechanism normally associated with fork repair, replication restart and recombination4,5, establishing new forks with the potential to sustain cell growth and division without an active origin. This potential is realised when roadblocks to fork progression are reduced or eliminated. It relies on the chromosome being circular, reinforcing the idea that replication initiation is triggered repeatedly by fork collision. The results reported raise the question of whether replication fork collisions have pathogenic potential for organisms that exploit multiple origins to replicate each chromosome. PMID:23892781

Minnesota's Historic Shipwrecks  

NSDL National Science Digital Library

Many a sailing vessel has found its way to the bottom of the Great Lakes, and there are hundreds of submerged shipwrecks scattered across the state of Minnesota in Lake Superior and other bodies of water. This website, designed by the Minnesota Historical Society, allows users to learn about these shipwrecks through historic photographs, preservation documents, and maps. Visitors can get started by looking over ships in the "Minnesota Lake Superior Shipwreck Exhibit". Here they will find information about ships like the Thomas Wilson, the Hesper, and the U.S.S. Essex, which now lies underneath the water outside of the Duluth harbor. Each profile contains information about the ship's history, its tonnage, and its current disposition. Moving along, the "Minnesota Lake Superior History" area contains an overview of human activity on the lake, along with information about the vessels that have plied their trade in the area. The site is rounded out by a copy of the state's shipwreck preservation plan.

South Fork Holston River basin 1988 biomonitoring  

SciTech Connect

There is concern over the effects of shifts in land use use practices on the aquatic fauna of streams in the South Fork Holston River basin in northwestern North Carolina and southwestern Virginia. Trout reproduction has noticeably declined in the Watauga River subbasin. The Watauga River and Elk River subbasins have been subjected to commercial and resort development. The Middle fork Holston River and the upper South Fork Holston River subbasins have been affected by agricultural and mining activities, respectively (Cox, 1986). To aid reclamation and management of the South Fork Holston basin, Tennessee Valley Authority (TVA) biologists conducted biomonitoring--including index of biotic integrity and macroinvertebrate sampling--on the Middle Fork Holston, South Fork Holston, Watauga, and Elk Rivers to assess cumulative impairment related to changes in habitat and pollutant loading in these subbasins. Biomonitoring can detect environmental degradation, help document problem areas, and assist in development of strategies for managing water quality. This report discusses the methods and materials and results of the biomonitoring of South Fork Holston River Basin. 13 refs., 5 figs., 12 tabs.

DEVILS FORK ROADLESS AREA, VIRGINIA.  

USGS Publications Warehouse

The Devils Fork Roadless Area occupies a tract of mountainous terrain in the Jefferson National Forest in southwestern Virginia. A mineral-resource survey indicated that coal is the principal mineral resource of the area, but its distribution, thickness, quantity and quality are conjectural because of the lack of exploratory drilling in the roadless area. However, several coal beds observed in adjacent areas are thick enough and persistent enough to warrant projection into the roadless area. Therefore the area has a probable resource potential and preliminary estimates show 55 million tons of coal resources to be present. Rocks underlying the area have a probable resource potential for gas. There is little promise for the occurrence of metallic mineral or oil resources.

Minnesota's Comprehensive Statewide Smokefree Law  

PubMed Central

Background Young adults have the highest rate of smoking among any age group. Purpose The purpose of this study is to assess the short-term effects of Minnesota’s comprehensive statewide smokefree law on young adult smoking perceptions and behavior. Methods Telephone surveys were conducted before and up to 18 months after Minnesota’s statewide smokefree law went into effect on October 1, 2007 (data analyzed 2010–2011). Participants included young adults from a population-based cohort in Minnesota (n=1458) and from five other upper Midwest states that serve as a comparison (n=248). Differences in perceptions and smoking behavior were examined between Minnesota participants who lived with and without a local smokefree law prior to Minnesota’s statewide law, and participants who lived in the comparison states. Results The majority of youth in Minnesota were aware of the smoking restrictions in restaurants and bars following the law. After implementation of the law, Minnesota participants who previously lived without a local law (versus comparison) were more likely to perceive fewer adult and peer smokers and less likely to report leaving social events early because it was too smoky. No changes in smoking behaviors were observed before and after the law. Minnesota participants, however, who lived without a prior law (versus participants with a prior law) were more likely to attribute a quit attempt after the law to smoking restrictions in restaurant and bars. Conclusions Results suggest that Minnesota’s law has changed perceptions of the tobacco environment. Longer-term follow-up may be needed to observe changes in smoking behavior. PMID:23079212

Aberrant DNA replication is a major source of the mutations and chromosome rearrangements that are associated with pathological disorders. When replication is compromised, DNA becomes more prone to breakage. Secondary structures, highly transcribed DNA sequences and damaged DNA stall replication forks, which then require checkpoint factors and specialized enzymatic activities for their stabilization and subsequent advance. These mechanisms ensure that

Anticipating chromosomal replication fork arrest: SSB targets repair DNA helicases to active forks.  

PubMed

In bacteria, several salvage responses to DNA replication arrest culminate in reassembly of the replisome on inactivated forks to resume replication. The PriA DNA helicase is a prominent trigger of this replication restart process, preceded in many cases by a repair and/or remodeling of the arrested fork, which can be performed by many specific proteins. The mechanisms that target these rescue effectors to damaged forks in the cell are unknown. We report that the single-stranded DNA binding (SSB) protein is the key factor that links PriA to active chromosomal replication forks in vivo. This targeting mechanism determines the efficiency by which PriA reaches its specific DNA-binding site in vitro and directs replication restart in vivo. The RecG and RecQ DNA helicases, which are involved in intricate replication reactivation pathways, also associate with the chromosomal replication forks by similarly interacting with SSB. These results identify SSB as a platform for linking a 'repair toolbox' with active replication forks, providing a first line of rescue responses to accidental arrest. PMID:17853894

Homologous Recombination as a Replication Fork Escort: Fork-Protection and Recovery  

PubMed Central

Homologous recombination is a universal mechanism that allows DNA repair and ensures the efficiency of DNA replication. The substrate initiating the process of homologous recombination is a single-stranded DNA that promotes a strand exchange reaction resulting in a genetic exchange that promotes genetic diversity and DNA repair. The molecular mechanisms by which homologous recombination repairs a double-strand break have been extensively studied and are now well characterized. However, the mechanisms by which homologous recombination contribute to DNA replication in eukaryotes remains poorly understood. Studies in bacteria have identified multiple roles for the machinery of homologous recombination at replication forks. Here, we review our understanding of the molecular pathways involving the homologous recombination machinery to support the robustness of DNA replication. In addition to its role in fork-recovery and in rebuilding a functional replication fork apparatus, homologous recombination may also act as a fork-protection mechanism. We discuss that some of the fork-escort functions of homologous recombination might be achieved by loading of the recombination machinery at inactivated forks without a need for a strand exchange step; as well as the consequence of such a model for the stability of eukaryotic genomes.

Phosphorylated RPA recruits PALB2 to stalled DNA replication forks to facilitate fork recovery.  

PubMed

Phosphorylation of replication protein A (RPA) by Cdk2 and the checkpoint kinase ATR (ATM and Rad3 related) during replication fork stalling stabilizes the replisome, but how these modifications safeguard the fork is not understood. To address this question, we used single-molecule fiber analysis in cells expressing a phosphorylation-defective RPA2 subunit or lacking phosphatase activity toward RPA2. Deregulation of RPA phosphorylation reduced synthesis at forks both during replication stress and recovery from stress. The ability of phosphorylated RPA to stimulate fork recovery is mediated through the PALB2 tumor suppressor protein. RPA phosphorylation increased localization of PALB2 and BRCA2 to RPA-bound nuclear foci in cells experiencing replication stress. Phosphorylated RPA also stimulated recruitment of PALB2 to single-strand deoxyribonucleic acid (DNA) in a cell-free system. Expression of mutant RPA2 or loss of PALB2 expression led to significant DNA damage after replication stress, a defect accentuated by poly-ADP (adenosine diphosphate) ribose polymerase inhibitors. These data demonstrate that phosphorylated RPA recruits repair factors to stalled forks, thereby enhancing fork integrity during replication stress. PMID:25113031

Fanconi anemia proteins stabilize replication forks.  

PubMed

Fanconi anemia (FA) is a recessive genetic disorder characterized by hypersensitivity to crosslinking agents that has been attributed to defects in DNA repair and/or replication. FANCD2 and the FA core complex bind to chromatin during DNA replication; however, the role of FA proteins during replication is unknown. Using Xenopus cell-free extracts, we show that FANCL depletion results in defective DNA replication restart following treatment with camptothecin, a drug that results in DSBs during DNA replication. This defect is more pronounced following treatment with mitomycin C, presumably because of an additional role of the FA pathway in DNA crosslink repair. Moreover, we show that chromatin binding of FA core complex proteins during DNA replication follows origin assembly and origin firing and is dependent on the binding of RPA to ssDNA while FANCD2 additionally requires ATR, consistent with FA proteins acting at replication forks. Together, our data suggest that FA proteins play a role in replication restart at collapsed replication forks. PMID:18786657

Stalled replication forks: making ends meet for recognition and stabilization.  

PubMed

In bacteria, PriA protein, a conserved DEXH-type DNA helicase, plays a central role in replication restart at stalled replication forks. Its unique DNA-binding property allows it to recognize and stabilize stalled forks and the structures derived from them. Cells must cope with fork stalls caused by various replication stresses to complete replication of the entire genome. Failure of the stalled fork stabilization process and eventual restart could lead to various forms of genomic instability. The low viability of priA null cells indicates a frequent occurrence of fork stall during normal growth that needs to be properly processed. PriA specifically recognizes the 3'-terminus of the nascent leading strand or the invading strand in a displacement (D)-loop by the three-prime terminus binding pocket (TT-pocket) present in its unique DNA binding domain. Elucidation of the structural basis for recognition of arrested forks by PriA should provide useful insight into how stalled forks are recognized in eukaryotes. PMID:20658707

Replication fork recovery and regulation of common fragile sites stability.  

PubMed

The acquisition of genomic instability is a triggering factor in cancer development, and common fragile sites (CFS) are the preferential target of chromosomal instability under conditions of replicative stress in the human genome. Although the mechanisms leading to CFS expression and the cellular factors required to suppress CFS instability remain largely undefined, it is clear that DNA becomes more susceptible to breakage when replication is impaired. The models proposed so far to explain how CFS instability arises imply that replication fork progression along these regions is perturbed due to intrinsic features of fragile sites and events that directly affect DNA replication. The observation that proteins implicated in the safe recovery of stalled forks or in engaging recombination at collapsed forks increase CFS expression when downregulated or mutated suggests that the stabilization and recovery of perturbed replication forks are crucial to guarantee CFS integrity.

Non-replicative helicases at the replication fork.  

PubMed

Reactivation of stalled or collapsed replication forks is an essential process in bacteria. Restart systems operate to restore the 5'-->3' replicative helicase, DnaB, to the lagging-strand template. However, other non-replicative 3'-->5' helicases play an important role in the restart process as well. Here we examine the DNA-binding specificity of three of the latter group, PriA, Rep, and UvrD. Only PriA and Rep display structure-specific fork binding. Interestingly, their specificity is opposite: PriA binds a leading-strand fork, presumably reflecting its restart activity in directing loading of DnaB to the lagging-strand template. Rep binds a lagging-strand fork, presumably reflecting its role in partially displacing Okazaki fragments that originate near the fork junction. This activity is necessary for generating a single-stranded landing pad for DnaB. While UvrD shows little structure-specificity, there is a slight preference for lagging-strand forks, suggesting that there might be some redundancy between Rep and UvrD and possibly explaining the observed synthetic lethality that occurs when mutations in the genes encoding these two proteins are combined.

Quartz Tuning Forks and Acoustic Phenomena: Application to Superfluid Helium  

NASA Astrophysics Data System (ADS)

Immersed mechanical resonators are well suited for probing the properties of fluids, since the surrounding environment influences the resonant characteristics of such oscillators in several ways. Quartz tuning forks have gained much popularity in recent years as the resonators of choice for studies of liquid helium. They have many superior properties when compared to other oscillating bodies conventionally used for this purpose, such as vibrating wires. However, the intricate geometry of a tuning fork represents a challenge for analyzing their behavior in a fluid environment—analytical approaches do not carry very far. In this article the characteristics of immersed quartz tuning fork resonators are studied by numerical simulations. We account for the compressibility of the medium, that is acoustic phenomena, and neglect viscosity, with the aim to realistically model the oscillator response in superfluid helium. The significance of different tuning fork shapes is studied. Acoustic emission in infinite medium and acoustic resonances in confined volumes are investigated. The results can aid in choosing a quartz tuning fork with suitable properties for experiments, as well as interpreting measured data.

More forks on the road to replication stress recovery  

PubMed Central

High-fidelity replication of DNA, and its accurate segregation to daughter cells, is critical for maintaining genome stability and suppressing cancer. DNA replication forks are stalled by many DNA lesions, activating checkpoint proteins that stabilize stalled forks. Stalled forks may eventually collapse, producing a broken DNA end. Fork restart is typically mediated by proteins initially identified by their roles in homologous recombination repair of DNA double-strand breaks (DSBs). In recent years, several proteins involved in DSB repair by non-homologous end joining (NHEJ) have been implicated in the replication stress response, including DNA-PKcs, Ku, DNA Ligase IV-XRCC4, Artemis, XLF and Metnase. It is currently unclear whether NHEJ proteins are involved in the replication stress response through indirect (signaling) roles, and/or direct roles involving DNA end joining. Additional complexity in the replication stress response centers around RPA, which undergoes significant post-translational modification after stress, and RAD52, a conserved HR protein whose role in DSB repair may have shifted to another protein in higher eukaryotes, such as BRCA2, but retained its role in fork restart. Most cancer therapeutic strategies create DNA replication stress. Thus, it is imperative to gain a better understanding of replication stress response proteins and pathways to improve cancer therapy.

Bellechester, Minnesota, USA, lagoon collapses  

NASA Astrophysics Data System (ADS)

Bellechester, Minnesota, is a small community of approximately 155 residents located on the county line between Goodhue and Wabasha counties in southeast Minnesota's karst region. Bellechester is served by a 21-year-old wastewater treatment facility (WWTF) consisting of three waste-stabilization ponds. On 28 April 1992 six sinkholes were discovered to have drained cell 2 of the WWTF resulting in the loss of approximately 8.7×106 1 of partially treated effluent and about 600 m3 of soil into previously undetected subsurface voids of unknown dimensions. In the week following the collapse, approximately 200 water wells located within a 5-km radius of the WWTF were sampled in an after-the-fact, emergency sampling program. Twelve samples with elevated fecal coliform levels, 18 samples with nitrate-nitrogen greater than the 10 mg/1 standard, and no samples with elevated chlorides were found. However, the elevated levels could not be unambiguously attributed to the WWTF collapse. This is the third WWTF to fail by sinkhole collapse in southeast Minnesota since 1974. All three collapsed lagoons have been located in similar geomorphic and stratigraphic settings. However, at least two lagoons have collapsed in the adjacent area in northeast Iowa, and these lagoons are located at different stratigraphic positions. Twenty-two WWTFs constructed in southeast Minnesota's karst region in the last 25 years have been identified as subject to potential sinkhole collapse. An unknown but significant number of manure storage lagoons, flood control structures, etc., have also been constructed in the karst region and are at risk. Public agencies are beginning to develop plans to deal with the risk associated with existing and future waste lagoons in this environment. The critical hydrogeologic parameters that can be used to prioritize the risk of collapse at existing facilities include: (1) the lithology of the first bedrock beneath each lagoon, (2) the thickness of surficial materials between the lagoon and the bedrock surface, (3) the presence and construction of liners (seepage rate), and (4) the proximity to existing sinkholes.

A multi-fork z-axis quartz micromachined gyroscope.  

PubMed

A novel multi-fork z-axis gyroscope is presented in this paper. Different from traditional quartz gyroscopes, the lateral electrodes of the sense beam can be arranged in simple patterns; as a result, the fabrication is simplified. High sensitivity is achieved by the multi-fork design. The working principles are introduced, while the finite element method (FEM) is used to simulate the modal and sensitivity. A quartz fork is fabricated, and a prototype is assembled. Impedance testing shows that the drive frequency and sense frequency are similar to the simulations, and the quality factor is approximately 10,000 in air. The scale factor is measured to be 18.134 mV/(°/s) and the nonlinearity is 0.40% in a full-scale input range of ±250 °/s. PMID:24048339

Characterization of the ATPase Activity of RecG and RuvAB Proteins on Model Fork Structures Reveals Insight into Stalled DNA Replication Fork Repair*  

PubMed Central

RecG and RuvAB are proposed to act at stalled DNA replication forks to facilitate replication restart. To clarify the roles of these proteins in fork regression, we used a coupled spectrophotometric ATPase assay to determine how these helicases act on two groups of model fork substrates: the first group mimics nascent stalled forks, whereas the second mimics regressed fork structures. The results show that RecG is active on the substrates in group 1, whereas these are poor substrates for RuvAB. In addition, in the presence of group 1 forks, the single-stranded DNA-binding protein (SSB) enhances the activity of RecG and enables it to compete with excess RuvA. In contrast, SSB inhibits the activity of RuvAB on these substrates. Results also show that the preferred regressed fork substrate for RuvAB is a Holliday junction, not a forked DNA. The active form of the enzyme on the Holliday junction contains a single RuvA tetramer. In contrast, although the enzyme is active on a regressed fork structure, RuvB loading by a single RuvA tetramer is impaired, and full activity requires the cooperative binding of two forked DNA substrate molecules. Collectively, the data support a model where RecG is responsible for stalled DNA replication fork regression. SSB ensures that if the nascent fork has single-stranded DNA character RuvAB is inhibited, whereas the activity of RecG is preferentially enhanced. Only once the fork has been regressed and the DNA is relaxed can RuvAB bind to a RecG-extruded Holliday junction. PMID:23893472

New histone supply regulates replication fork speed and PCNA unloading  

PubMed Central

Correct duplication of DNA sequence and its organization into chromatin is central to genome function and stability. However, it remains unclear how cells coordinate DNA synthesis with provision of new histones for chromatin assembly to ensure chromosomal stability. In this paper, we show that replication fork speed is dependent on new histone supply and efficient nucleosome assembly. Inhibition of canonical histone biosynthesis impaired replication fork progression and reduced nucleosome occupancy on newly synthesized DNA. Replication forks initially remained stable without activation of conventional checkpoints, although prolonged histone deficiency generated DNA damage. PCNA accumulated on newly synthesized DNA in cells lacking new histones, possibly to maintain opportunity for CAF-1 recruitment and nucleosome assembly. Consistent with this, in vitro and in vivo analysis showed that PCNA unloading is delayed in the absence of nucleosome assembly. We propose that coupling of fork speed and PCNA unloading to nucleosome assembly provides a simple mechanism to adjust DNA replication and maintain chromatin integrity during transient histone shortage.

Land use management in Minnesota  

NASA Technical Reports Server (NTRS)

The author has identified the following significant results. Preliminary analysis of bulk imagery suggests that the forty-acre data cell used in the Minnesota Land Management Information Systems (MLMIS) can be utilized in interpretation of ERTS-1 data. High quality bulk images of the Twin Cities metropolitan area suggest that detail in urban land use patterns is much greater than originally anticipated. This implies a greater work effort in this area than was planned. Furthermore, the forest classes of land use can also be usefully divided into subcategories. Preliminary analysis of one rather low quality image also indicates that subclasses of wetlands can be identified. Prospects are bright for improving the potential detail that ERTS-1 can contribute to MLMIS.

To give one an idea of the breadth of the exhibits, there are fourteen listed in History alone, including exhibits on China, Greece, Egypt, Anglo-Saxon England, cultures of Minnesota, Medieval Europe, and Vikings in America. The exhibits are varied in layout and content, but they generally contain substantial content in both hypertext and images. The exhibits can be browsed by the subjects listed above or via their position in the E-museum's floor plan. Of course, there is a marked emphasis on Minnesota and topics relevant to Minnesota here, which makes it an excellent Website for teachers in the land of 10,000 lakes to use for resources and ideas.

Quaternary geologic map of Minnesota  

NASA Technical Reports Server (NTRS)

The Quaternary Geologic Map of Minnesota is a compilation based both on the unique characteristics of satellite imagery and on the results of previous field investigations, both published and unpublished. The use of satellite imagery has made possible the timely and economical construction of this map. LANDSAT imagery interpretation proved more useful than expected. Most of the geologic units could be identified by extrapolating from specific sites where the geology had been investigated into areas where little was known. The excellent geographic registry coupled with the multi-spectral record of these images served to identify places where the geologic materials responded to their ecological environment and where the ecology responded to the geologic materials. Units were well located on the map at the scale selected for the study. Contacts between till units could be placed with reasonable accuracy. The reference points that were used to project delineations between units (rivers, lakes, hills, roads and other features), which had not been accurately located on early maps, could be accurately located with the help of the imagery. The tonal and color contrasts, the patterns reflecting geologic change and the resolution of the images permitted focusing attention on features which could be represented at the final scale of the map without distraction by other interesting but site-specific details.

Methane Production in Minnesota Peatlands  

PubMed Central

Rates of methane production in Minnesota peats were studied. Surface (10- to 25-cm) peats produced an average of 228 nmol of CH4 per g (dry weight) per h at 25°C and ambient pH. Methanogenesis rates generally decreased with depth in ombrotrophic peats, but on occasion were observed to rise within deeper layers of certain fen peats. Methane production was temperature dependent, increasing with increasing temperature (4 to 30°C), except in peats from deeper layers. Maximal methanogenesis from these deeper regions occurred at 12°C. Methane production rates were also pH dependent. Two peats with pHs of 3.8 and 4.3 had an optimum rate of methane production at pH 6.0. The addition to peat of glucose and H2-CO2 stimulated methanogenesis, whereas the addition of acetate inhibited methanogenesis. Cysteine-sulfide, nitrogen-phosphorus-trace metals, and vitamins-yeast extract affected methane production very little. Various gases were found to be trapped or dissolved (or both) within peatland waters. Dissolved methane increased linearly to a depth of 210 cm. The accumulation of metabolic end products produced within peat bogs appears to be an important mechanism limiting carbon turnover in peatland environments. PMID:16346565

Scrap tire recycling in Minnesota  

SciTech Connect

The author discusses the problems associated with scrap tires. For example, surface storing of scrap tires poses a fire hazard and the rainwater trapped in the tire casings is an ideal breeding ground for mosquitoes. Use as a fuel for energy production is unattractive as long as oil retails at its present low price. Past reclamation processes have not met expectations. Legislation alone is not the answer, because scrap tires cannot be regulated out of existence. However, the Minnesota state legislature has come up with an approach that seems to be successful. It has passed the Waste Tire Act, which not only formulates regulations but also provides funding for research and development. Thus, it has established a tire disposal fund for financing construction costs of tire recycling facilities. One of the outcomes was the construction of the St. Louis county Waste Tire Recycling Facility. Through a leasing arrangement with Minneapolis-based Rubber Elastomerics, Inc. (RRE), construction costs financed by the tire disposal fund eventually will be repaid by RRE to the fund. The arrangement is described in detail. By a process also described, RRE produces a product that can be used in thermoset and in thermoplastic compounds. The user can incorporate between 50 percent and 85 percent of the recycled product into a rubber or plastic compound without significantly affecting the physical properties of the compound.

Methane flux from Minnesota peatlands  

SciTech Connect

Northern (> 40 deg N) wetlands have been suggested as the largest natural source of methane (CH{sub 4}) to the troposphere. To refine the authors estimates of source strengths from this region and to investigate climatic controls on the process, fluxes were measured from a variety of Minnesota peatlands during May, June, and August 1986. Late spring and summer fluxes ranged from 11 to 866 mg CH{sub 4}/sq/m/day, averaging 207 mg CH{sub 4} sq/m/day overall. At Marcell Forest, forested bogs and fen sites had lower fluxes than open bogs. In the Red Lake peatland, circumneutral fens, with standing water above the peat surface, produced more methane than acid bog sites in which the water table was beneath the moss surface. Peat temperature was an important control. Methane flux increased in response to increasing soil temperature. It is estimated that the methane flux from all peatlands north of 40 deg may be on the order of 70 to 90 Tg/yr though estimates of this sort are plagued by uncertainties in the areal extent of peatlands, length of the CH{sub 4} producing season, and the spatial and temporal variability of the flux. 60 refs., 7 figs., 5 tabs.

A description of the hydrologic system and the effects of coal mining on water quality in the East Fork Little Chariton River and the alluvial aquifer between Macon and Huntsville, north-central Missouri  

USGS Publications Warehouse

The quality of surface and groundwater has been affected by abandoned strip mines and by abandoned underground mines in a 110-sq mi subbasin of the East Fork Little Chariton River. More than 14% of the area was strip mined for coal before 1979. The hydrologic system in the area was investigated and the effects of coal mining on quality of water in the river and alluvial aquifer were analyzed, with major emphasis on defining strip-mining effects. The groundwater gradient was from glacial drift or coal spring to alluvium to the East Fork Little Chariton River, and was greatest in spring and least in fall. Seepage from alluvium to the East Fork Little Chariton River occurs throughout the year, except during drought conditions when the only river flow is water released from Long Branch Lake. In the East Fork Little Chariton River median dissolved-solids concentrations increased from 153 mg/L near Macon to 630 mg/L near Huntsville and median sulfate concentrations increased from 36 mg/L near Macon to 360 mg/L near Huntsville. The median dissolved-solids concentration in water from the alluvium increased from 408 mg/L upstream from the strip mines to 641 mg/L near the mines and median dissolved-sulfate concentration increased from 140 to 350 mg/L. The sulfate-to-chloride ratio, used as the most sensitive indicator of strip-mining effects, increased markedly downstream in the East Fork Little Chariton River and nearby Middle Fork Little Chariton River, which also is affected by strip mining. There were no significant increases in sulfate-to-chloride ratio and dissolved-solids concentrations in comparable nearby subbasins of the Grand, Thompson, and Chariton Rivers where there was no mining.

Explorations in Hubble Space: A Quantitative Tuning Fork  

E-print Network

In order to establish an objective framework for studying galaxy morphology, we have developed a quantitative two-parameter description of galactic structure that maps closely on to Hubble's original tuning fork. Any galaxy can be placed in this "Hubble space", where the x-coordinate measures position along the early-to-late sequence, while the y-coordinate measures in a quantitative way the degree to which the galaxy is barred. The parameters defining Hubble space are sufficiently robust to allow the formation of Hubble's tuning fork to be mapped out to high redshifts. In the present paper, we describe a preliminary investigation of the distribution of local galaxies in Hubble space, based on the CCD imaging atlas of Frei et al. (1996). We find that barred, weakly-barred, and unbarred galaxies are remarkably well-separated on this diagnostic diagram. The spiral sequence is clearly bimodal and indeed approximates a tuning fork: strongly-barred and unbarred spirals do not simply constitute the extrema of a smooth unimodal distribution of bar strength, but rather populate two parallel sequences. Strongly barred galaxies lie on a remarkably tight sequence, strongly suggesting the presence of an underlying unifying physical process. Rather surprisingly, weakly barred systems do not seem to correspond to objects bridging the parameter space between unbarred and strongly barred galaxies, but instead form an extension of the regular spiral sequence. This relation lends support to models in which the bulges of late-type spirals originate from secular processes driven by bars.

Recovery of Arrested Replication Forks by Homologous Recombination Is Error-Prone  

PubMed Central

Homologous recombination is a universal mechanism that allows repair of DNA and provides support for DNA replication. Homologous recombination is therefore a major pathway that suppresses non-homology-mediated genome instability. Here, we report that recovery of impeded replication forks by homologous recombination is error-prone. Using a fork-arrest-based assay in fission yeast, we demonstrate that a single collapsed fork can cause mutations and large-scale genomic changes, including deletions and translocations. Fork-arrest-induced gross chromosomal rearrangements are mediated by inappropriate ectopic recombination events at the site of collapsed forks. Inverted repeats near the site of fork collapse stimulate large-scale genomic changes up to 1,500 times over spontaneous events. We also show that the high accuracy of DNA replication during S-phase is impaired by impediments to fork progression, since fork-arrest-induced mutation is due to erroneous DNA synthesis during recovery of replication forks. The mutations caused are small insertions/duplications between short tandem repeats (micro-homology) indicative of replication slippage. Our data establish that collapsed forks, but not stalled forks, recovered by homologous recombination are prone to replication slippage. The inaccuracy of DNA synthesis does not rely on PCNA ubiquitination or trans-lesion-synthesis DNA polymerases, and it is not counteracted by mismatch repair. We propose that deletions/insertions, mediated by micro-homology, leading to copy number variations during replication stress may arise by progression of error-prone replication forks restarted by homologous recombination.

Minnesota Tribal Coalition - Final Report  

SciTech Connect

The project helped tribal leaders, staff and community members on the Grand Portage, Leech Lake, and White Earth Reservations better understand their community's energy usage, assess local resources that might be utilized to reduce energy consumption and begin to formulate appropriate development strategies. The principal guiding interest was to assess energy usage and the potential for wind resource development on each of the three reservations. Key tribal staff became familiar with wind energy technology and assessment methodologies that will be of continued use as each tribe moves forward with development projects. The findings were that wind resources are available at each reservation with varying degrees of potential for development. At White Earth moderate to excellent resources are present at White Earth village and along the U.S. 59 corridor sufficient to be tapped to serve several scattered tribal complexes. At Grand Portage a former community television repeater tower site provides a viable elevated location for a wind turbine to serve the tribal community settlement. At Leech Lake, while most constrained by tree cover, a site adjacent to a casino holds promise for the newer taller wind turbines now coming to market at ever-increasing taller rotor heights. The project developed considerable data of importance regarding the potential for wind development on and near each reservation.

A pollen diagram from Kirchner Marsh, southeastern Minnesota, records a continuous vegetation sequence from the time of Late Wisconsin ice retreat from the region. The late-glacial and early postglacial portions of the diagram are correlated with a radiocarbon-dated diagram from Madelia, Minnesota. Both diagrams show a series of maxima of pollen types in the early postglacial that suggest a significant climatic change at that time. The Kirchner diagram, in addition, shows high percentages of nonarboreal pollen later in the postglacial that indicate an advance of prairie elements into the area between 7200 and 5000 years ago.

Time of travel of solutes in the East Fork Trinity River, November 1975; and Elm Fork Trinity River, December 1975; Trinity River Basin, Texas  

USGS Publications Warehouse

In Texas, the time of travel of solutes in the East Fork Trinity River and the Elm Fork Trinity River was determined in 1975 by injecting a fluorescent dye (Rhodamine WT, 20-percent solution) that could be detected by fluorometric analysis of water samples collected at selected downstream sites. Plots of dye concentration versus time were made for each injection and sampling site. The graphs were then used to determine arrival times of the leading edge, the peak, and the trailing edge of the dye cloud. The study in November 1975 was conducted on the East Fork Trinity River from just below the Rockwall-Forney Dam at Lake Ray Hubbard to the confluence with the Trinity River, a distance of 27.0 miles. The study in December 1975 was conducted on the Elm Fork Trinity River from just below the dam at Lewisville Lake to the Spur 482 crossing, a distance of 25.7 miles. (Woodard-USGS)

Substrate-selective repair and restart of replication forks by DNA translocases  

PubMed Central

SUMMARY Stalled replication forks are sources of genetic instability. Multiple fork remodeling enzymes are recruited to stalled forks, but how they work to promote fork restart is poorly understood. By combining ensemble biochemical assays and single molecule studies with magnetic tweezers, we show that SMARCAL1 branch migration and DNA annealing activities are directed by the single-stranded DNA binding protein RPA to selectively regress stalled replication forks caused by blockage to the leading-strand polymerase and to restore normal replication forks with a lagging-strand gap. We unveil the molecular mechanisms by which RPA enforces SMARCAL1 substrate preference. E. coli RecG acts similarly to SMARCAL1 in the presence of E. coli SSB, whereas the highly related human protein ZRANB3 has different substrate preferences. Our findings identify the important substrates of SMARCAL1 in fork repair, suggest that RecG and SMARCAL1 are functional orthologues, and provide a comprehensive model of fork repair by these DNA translocases.

Mutual interactions of oscillating quartz tuning forks in superfluid 4He  

NASA Astrophysics Data System (ADS)

The quartz tuning fork has recently become a popular experimental tool for investigations of both classical and quantum turbulence in cryogenic helium. Its increased use in low-temperature experiments and a number of puzzling results obtained in the past have led to many questions concerning the interaction of multiple tuning forks or the interaction of tuning forks with other oscillators. We report measurements performed in He II at low temperatures around 360 mK, on the mutual interaction of tuning forks placed in the same volume of fluid, and examine the responsible mechanisms in an effort to discriminate between acoustic coupling and interaction via quantized vortices. To this end, the interaction of two tuning forks is investigated by analyzing their recorded resonance curves, looking for any nonelectrical crosstalk. Further, the force-velocity characteristics of a detector tuning fork are measured for different operating velocities of a generator tuning fork. As a complementary measurement, the intensity of sound waves is recorded using a set of miniature receivers. We confirm the current knowledge on acoustic emission by tuning forks in He II and verify properties of their radiation patterns. We conclude that in our experiment the interaction is almost entirely mediated by sound waves.

Camptothecin, a specific inhibitor of type I DNA topoisomerase, induces DNA breakage at replication forks  

SciTech Connect

The structure of replicating simian virus 40 minichromosomes, extracted from camptothecin-treated infected cells, was investigated by biochemical and electron microscopic methods. The authors found that camptothecin frequently induced breaks at replication forks close to the replicative growth points. Replication branches were disrupted at about equal frequencies at the leading and the lagging strand sides of the fork. Since camptothecin is known to be a specific inhibitor of type I DNA topoisomerase, the authors suggest that this enzyme is acting very near the replication forks. This conclusion was supported by experiments with aphidicolin, a drug that blocks replicative fork movement, but did not prevent the camptothecin-induced breakage of replication forks. The drug teniposide, and inhibitor of type II DNA topoisomerase, had only minor effects on the structure of these replicative intermediates.

Chemical sensor based on microfabricated wristwatch tuning forks.  

PubMed

We report here a chemical sensor based on detecting the mechanical response of a thin (approximately 10-microm) polymer wire stretched across the two prongs of a wristwatch quartz tuning fork (QTF). When the fork is set to oscillate, the wire is stretched and compressed by the two prongs. The stretching/compression force changes upon adsorption of analyte molecules onto/into the polymer wire, which is detected by the QTF with pico-Newton force sensitivity. An array of such sensors with different polymer wires is used for simultaneous detection of several analytes and for improvement of pattern recognition. The low cost (approximately 10 cent) of the QTF, together with that an array of QTFs can be driven to oscillate simultaneously and their resonance frequencies detected with the same circuit, promises a high performance, low cost, and portable sensor for detecting various chemical vapors. We demonstrate here detection of parts-per-billion-level water, ethylnitrobenzene, and ethanol vapors using the QTF arrays. PMID:15859583

CtIP mediates replication fork recovery in a FANCD2-regulated manner.  

PubMed

Fanconi anemia (FA) is a chromosome instability syndrome characterized by increased cancer predisposition. Within the FA pathway, an upstream FA core complex mediates monoubiquitination and recruitment of the central FANCD2 protein to sites of stalled replication forks. Once recruited, FANCD2 fulfills a dual role towards replication fork recovery: (i) it cooperates with BRCA2 and RAD51 to protect forks from nucleolytic degradation and (ii) it recruits the BLM helicase to promote replication fork restart while suppressing new origin firing. Intriguingly, FANCD2 and its interaction partners are also involved in homologous recombination (HR) repair of DNA double-strand breaks, hinting that FANCD2 utilizes HR proteins to mediate replication fork recovery. One such candidate is CtIP (CtBP-interacting protein), a key HR repair factor that functions in complex with BRCA1 and MRE11, but has not been investigated as putative player in the replication stress response. Here, we identify CtIP as a novel interaction partner of FANCD2. CtIP binds and stabilizes FANCD2 in a DNA damage- and FA core complex-independent manner, suggesting that FANCD2 monoubiquitination is dispensable for its interaction with CtIP. Following cellular treatment with a replication inhibitor, aphidicolin, FANCD2 recruits CtIP to transiently stalled, as well as collapsed, replication forks on chromatin. At stalled forks, CtIP cooperates with FANCD2 to promote fork restart and the suppression of new origin firing. Both functions are dependent on BRCA1 that controls the step-wise recruitment of MRE11, FANCD2 and finally CtIP to stalled replication forks, followed by their concerted actions to promote fork recovery.

Monitoring Fine Sediment; Grande Ronde and John Day Rivers, 2000 Annual Report.  

SciTech Connect

Fine sediment in spawning substrate has a major effect on salmon survival from egg to smolt. Basin-wide restoration plans have established targets for fine sediment levels in spawning habitat. The project was initiated to monitor surface fine sediment levels and overwinter intrusion of fine sediment in spring chinook salmon spawning habitat in the North Fork John Day (NFJDR) and Grande Ronde Rivers, for five years. The project is also investigating the potential relationship between surface fine levels and overwinter sedimentation. It will provide data to assess trends in substrate conditions in monitored reaches and whether trends are consistent with efforts to improve salmon habitat conditions. The data on the magnitude of overwinter sedimentation will also be used to estimate salmon survival from egg to emergence. In Sept. 1998, 1999, and Aug. 2000, sites for monitoring overwinter sedimentation were established in salmon spawning habitat in the upper Grande Ronde River, Catherine Creek (a Grande Ronde tributary), the North Fork John Day River (NFJDR), and Granite Creek (a NFJDR tributary). Surface fine sediment levels were measured in these reaches via the grid method and visually estimated to test the relative accuracy of these two methods. In 1999 and 2000, surface fine sediment was also estimated via pebble counts at selected reaches to allow comparison of results among the methods. Overwintering substrate samples were collected in April 1999 and April-May 2000 to estimate the amount of overwinter sedimentation in clean gravels in spawning habitat. Monitoring methods and locations are described.

Dynamics of quartz tuning fork force sensors used in scanning probe microscopy.  

PubMed

We have performed an experimental characterization of the dynamics of oscillating quartz tuning forks which are being increasingly used in scanning probe microscopy as force sensors. We show that tuning forks can be described as a system of coupled oscillators. Nevertheless, this description requires knowledge of the elastic coupling constant between the prongs of the tuning fork, which has not yet been measured. Therefore, tuning forks have usually been described within the single oscillator or the weakly coupled oscillators approximation that neglects the coupling between the prongs. We propose three different procedures to measure the elastic coupling constant: an opto-mechanical method, a variation of the Cleveland method and a thermal noise based method. We find that the coupling between the quartz tuning fork prongs has a strong influence on the dynamics and the measured motion is in remarkable agreement with a simple model of coupled harmonic oscillators. The precise determination of the elastic coupling between the prongs of a tuning fork allows us to obtain a quantitative relation between the resonance frequency shift and the force gradient acting at the free end of a tuning fork prong.

Depositional environments of the Red Fork Sandstone in Custer and Roger Mills Counties, southwestern Oklahoma  

SciTech Connect

The Desmoinesian Red Fork formation is a prolific, overpressured gas-producing sequence of interbedded sandstones and shales. Total thickness ranges from less than 100 ft (northeast) to more than 1100 ft (south). Isopach maps suggest that syndepositional faulting controlled major depositional trends. The lower Red Fork, whose base is defined by a persistent, hot, black shale (sequence boundary ), is mainly deep-marine shale and siltstone. Two major shallowing-upward deltaic sequences separated by a marine transgression are evident in the middle (50-400-ft thick) and upper (30-250-ft thick) Red Fork. The middle Red Fork is marine dominated and was deposited into a relatively deep basin on a steep, unstable delta-front slope. In contrast, the upper Red Fork deltaic sequence is more fluvial dominated and was deposited in shallower water. The upper Red Fork is overlain by the Pink lime interval which appears to be shallow-marine/lagoonal black shale. The Pink lime contains fish scales, coffee-ground to branch-size lignitic plant debris, and brackish to shallow-marine ostracodes, linguloid brachiopods, Tasmanites algae, and gastropods. Most of the Red Fork has an easterly, possibly Ouachita Mountain area source. The prolific Southwest Leedey field has a different mineral assemblage and diagenetic sequence and may have a northern source.

Frequency Characteristics of a Quartz Tuning Fork Immersed in He II  

NASA Astrophysics Data System (ADS)

The effect of dissipation on frequency characteristics of tuning forks was measured, the dissipation being induced by acoustic radiation of different wavelengths, excited by tuning forks. The tuning forks have been immersed in the superfluid helium. The fork resonance frequencies 32, 77 and 99 kHz have been measured at T=370 mK in the pressure range between SVP and 24.9 atm. Most of the tuning forks have been studied in a commercial can. It is found that at wavelength ?>0.6 cm the frequency dependence is determined by the relationship between density and pressure. It is established that a decrease in wavelength enhances influence of the acoustic radiation on the fork oscillation frequency. In the case where the sound wavelength is equal to the can internal diameter an acoustic resonance occurs. The frequency reaches values higher than the fork frequency in vacuum. Further reduction of the sound wavelength leads to the situation when the resonant frequency is similar to the frequency at long wavelengths.

Replication forks reverse at high frequency upon replication stress in Physarum polycephalum.  

PubMed

The addition of hydroxyurea after the onset of S phase allows replication to start and permits the successive detecting of replication-dependent joint DNA molecules and chicken foot structures in the synchronous nuclei of Physarum polycephalum. We find evidence for a very high frequency of reversed replication forks upon replication stress. The formation of these reversed forks is dependent on the presence of joint DNA molecules, the impediment of the replication fork progression by hydroxyurea, and likely on the propensity of some replication origins to reinitiate replication to counteract the action of this compound. As hydroxyurea treatment enables us to successively detect the appearance of joint DNA molecules and then of reversed replication forks, we propose that chicken foot structures are formed both from the regression of hydroxyurea-frozen joint DNA molecules and from hydroxyurea-stalled replication forks. These experiments underscore the transient nature of replication fork regression, which becomes detectable due to the hydroxyurea-induced slowing down of replication fork progression. PMID:24951952

Quartz tuning fork as a viscometer for Helium liquids  

NASA Astrophysics Data System (ADS)

Oscillating beams serve as simple systems for measuring effects of energy dissipation as a result of interaction with their environment. Especially in miniature mechanical oscillators, the enhanced surface-to-volume ratio signifies the importance of damping caused by drag force. We have investigated the mechanical response of commercial miniature quartz tuning forks with a natural resonant frequency of 32.768 kHz. The changes in resonance frequency and damping have been measured at various Helium and Nitrogen gas pressures and various temperatures. Our results will be compared with theoretical predictions in order to extend its application to the sub-millikelvin temperature range as an effective thermometer in superfluid ^3He.

Quartz Tuning Fork (QTF)-based Scanning Probe Microscopy (SPM) is an important field of research. A suitable model for the QTF is important to obtain quantitative measurements with these devices. Analytical models have the limitation of being based on the double cantilever configuration. In this paper, we present an electromechanical finite element model of the QTF electrically excited with two free prongs. The model goes beyond the state-of-the-art of numerical simulations currently found in the literature for this QTF configuration. We present the first numerical analysis of both the electrical and mechanical behavior of QTF devices. Experimental measurements obtained with 10 units of the same model of QTF validate the finite element model with a good agreement. PMID:23722828

Sediment Mobilization in Ravines Draining Minnesota Cropland  

NASA Astrophysics Data System (ADS)

In recent years, studies have found that Lake Pepin, a naturally-dammed lake on the Mississippi River on the border of Minnesota and Wisconsin, is filling in with sediment at an alarming rate. Most of this sediment comes from the Minnesota River, which contributes about 80% of all the sediment being deposited in Lake Pepin, even though it contains only 35% of the upstream area. This study focuses on understanding sediment derived from ravine erosion in a tributary of the Minnesota River basin through event monitoring of two ravines in the Le Sueur River watershed. Ravines represent one of the key sediment sources in the Le Sueur watershed, with sediment mobilized through ravine widening and headcutting. In addition, sediment may be mobilized through riverbank and bluff erosion and erosion of the topsoil. A major effort is underway to reduce the amount of sediment in the Minnesota River and Lake Pepin, so we must discover what is causing the sediment to be mobilized and when. Dominant land use in the area is agricultural with over 90% of the crops consisting of row crops. Field drainage in these agricultural areas is heavily influenced by the installation of drainage ditches and drain tile. While this has increased crop yield, it has altered the natural drainage of the area. Southern Minnesota is covered by a thick layer of glacial till allowing the landscape to rapidly respond to hydrologic conditions within a relatively short amount of time, and those changes could include ravine widening or elongation. To better understand how ravines respond to different hydrologic events, we monitored ravines over the course of one monitoring season. From April-October 2013, three Sigma 930 automated samplers measured discharge and collected water samples for total suspended sediment analysis at three sites in two ravines. We tested whether the volume, intensity or seasonality of precipitation events is most important in mobilizing sediment in the ravines. Data are being analyzed to calculate sediment budgets and identify key hydrologic factors that control sediment movement out of these ravines and into the river.

The DNA helicase Pfh1 promotes fork merging at replication termination sites to ensure genome stability  

PubMed Central

Bidirectionally moving DNA replication forks merge at termination sites composed of accidental or programmed DNA–protein barriers. If merging fails, then regions of unreplicated DNA can result in the breakage of DNA during mitosis, which in turn can give rise to genome instability. Despite its importance, little is known about the mechanisms that promote the final stages of fork merging in eukaryotes. Here we show that the Pif1 family DNA helicase Pfh1 plays a dual role in promoting replication fork termination. First, it facilitates replication past DNA–protein barriers, and second, it promotes the merging of replication forks. A failure of these processes in Pfh1-deficient cells results in aberrant chromosome segregation and heightened genome instability. PMID:22426535

Redundant functions between priB and priC and synthetic lethality between priA2::kan and rep3 mutations raise the possibility that there may be multiple pathways for restarting replication forks in vivo. Herein, it is shown

RNF4 and PLK1 are required for replication fork collapse in ATR-deficient cells  

PubMed Central

The ATR–CHK1 axis stabilizes stalled replication forks and prevents their collapse into DNA double-strand breaks (DSBs). Here, we show that fork collapse in Atr-deleted cells is mediated through the combined effects the sumo targeted E3-ubiquitin ligase RNF4 and activation of the AURKA–PLK1 pathway. As indicated previously, Atr-deleted cells exhibited a decreased ability to restart DNA replication following fork stalling in comparison with control cells. However, suppression of RNF4, AURKA, or PLK1 returned the reinitiation of replication in Atr-deleted cells to near wild-type levels. In RNF4-depleted cells, this rescue directly correlated with the persistence of sumoylation of chromatin-bound factors. Notably, RNF4 repression substantially suppressed the accumulation of DSBs in ATR-deficient cells, and this decrease in breaks was enhanced by concomitant inhibition of PLK1. DSBs resulting from ATR inhibition were also observed to be dependent on the endonuclease scaffold protein SLX4, suggesting that RNF4 and PLK1 either help activate the SLX4 complex or make DNA replication fork structures accessible for subsequent SLX4-dependent cleavage. Thus, replication fork collapse following ATR inhibition is a multistep process that disrupts replisome function and permits cleavage of the replication fork. PMID:24142876

Human Timeless and Tipin stabilize replication forks and facilitate sister-chromatid cohesion  

PubMed Central

The Timeless-Tipin protein complex has been reported to be important for replication checkpoint and normal DNA replication processes. However, the precise mechanisms by which Timeless-Tipin preserves genomic integrity are largely unclear. Here, we describe the roles of Timeless-Tipin in replication fork stabilization and sister chromatid cohesion. We show in human cells that Timeless is recruited to replication origin regions and dissociate from them as replication proceeds. Cdc45, which is known to be required for replication fork progression, shows similar patterns of origin association to those of Timeless. Depletion of Timeless-Tipin causes chromosome fragmentation and defects in damage repair in response to fork collapse, suggesting that it is required for replication fork maintenance under stress. We also demonstrate that depletion of Timeless-Tipin impairs sister chromatid cohesion and causes a defect in mitotic progression. Consistently, Timeless-Tipin co-purifies with cohesin subunits and is required for their stable association with chromatin during S phase. Timeless associates with the cohesion-promoting DNA helicase ChlR1, which, when overexpressed, partially alleviates the cohesion defect of cells depleted of Timeless-Tipin. These results suggest that Timeless-Tipin functions as a replication fork stabilizer that couples DNA replication with sister chromatid cohesion established at replication forks. PMID:20124417

Irrigation survey in Sherburne County, Minnesota  

NASA Technical Reports Server (NTRS)

Approximately 70% of Minnesota's irrigation is with center pivot distribution systems whose diagnostic appearance on remotely sensed imagery is a circular pattern which can be readily identified on LANDSAT MSS band imagery. Fields irrigated with traveling guns, laterals, booms, or cornering systems either result in angular field patterns or obscure the circular patterns normally visible on imagery. The IDMS system at Goddard was used to develop a LANDSAT digital classification of the Sherburne County area, which located fields regardless of shape, and was not dependent of visual interpretation. Ground truth collection and classification attempts are described in an effort to inventory all wells in the area.

The Karst Feature Database (KFD) of Minnesota is a relational GIS-based Database Management System (DBMS). Previous karst feature datasets used inconsistent attributes to describe karst features in different areas of Minnesota. Existing metadata were modified and standardized to represent a comprehensive metadata for all the karst features in Minnesota. Microsoft Access 2000 and ArcView 3.2 were used to develop this working database. Existing county and sub-county karst feature datasets have been assembled into the KFD, which is capable of visualizing and analyzing the entire data set. By November 17 2002, 11,682 karst features were stored in the KFD of Minnesota. Data tables are stored in a Microsoft Access 2000 DBMS and linked to corresponding ArcView applications. The current KFD of Minnesota has been moved from a Windows NT server to a Windows 2000 Citrix server accessible to researchers and planners through networked interfaces. ?? Springer-Verlag 2005.

Bioavailability of mercury in East Fork Poplar Creek soils  

SciTech Connect

The initial risk assessment for the East Fork Poplar Creek (EFPC) floodplain in Oak Ridge, Tennessee, a superfund site heavily contaminated with mercury, was based upon a reference dose for mercuric chloride, a soluble mercury compound not expected to be present in the floodplain, which is frequently saturated with water. Previous investigations had suggested mercury in the EFPC floodplain was less soluble and therefore less bioavailable than mercuric chloride, possibly making the results of the risk assessment unduly conservative. A bioavailability study, designed to measure the amount of mercury available for absorption in a child`s digestive tract, the most critical risk endpoint and pathway, was performed on twenty soils from the EFPC floodplain. The average percentage of mercury released during the study for the twenty soils was 5.3%, compared to 100% of the compound mercuric chloride subjected to the same conditions. Alteration of the procedure to test additional conditions possible during soil digestion did not appreciably alter the results. Therefore, use of a reference dose for mercuric chloride in the EFPC risk assessment without inclusion of a corresponding bioavailability factor may be unduly conservative.

Regional Ecorisk Field investigation, upper Clark Fork River Basin  

SciTech Connect

The Regional Ecorisk Field Investigation was conducted at the Clark Fork River Superfund Site (Montana) to evaluate the relationships between plant communities and tailings deposits in riparian habitats and to evaluate food-chain transfer of trace elements to selected wildlife species. Stations were selected to represent a range of vegetation biomass (or cover) values and apparent impact of trace elements, with some areas of lush vegetation, some areas of mostly unvegetated soil (e.g., < 30 percent plant cover), and a gradient in between. For the evaluation of risk to wildlife, bioaccumulation of metals was evaluated in native or naturalized plants, terrestrial invertebrates, and the deer mouse (Peromyscus maniculatus). Potential reproductive effects in the deer mouse were evaluated by direct measurements. For other wildlife species, bioaccumulation data were interpreted in the context of food web exposure models. Total biomass and species richness of riparian plant communities are related to tailings content of soil as indicated by pH and metals concentrations. Risk to populations of omnivorous small mammals such as the deer mouse was not significant. Relative abundance and reproductive condition of the deer mouse were normal, even in areas of high metals enrichment. Based on exposure models and site-specific tissue residue data for dietary species, risk to local populations of predators such as red fox and American kestrel that feed on deer mice and terrestrial invertebrates is not significant. Risk to herbivores related to metals bioaccumulation in plant tissues is not significant. Population level effects in deer and other large wildlife are not expected because of the large home ranges of such species and compensatory demographic factors.

Dynamics of probes attached to quartz tuning forks for the detection of surface forces  

NASA Astrophysics Data System (ADS)

The dynamics of force microscopy probes attached to quartz tuning fork piezoelectric sensors has been investigated, by simply modeling the tuning fork/probe system as two coupled damped harmonic oscillators. Depending on how probes are applied to the tuning fork prong, they could show appreciable compliance along the direction of approach to the surface. In particular, buckling or bending deformation of the probe may account for unexpectedly long interaction ranges found in experimental approach curves. Some peculiar curves found in the literature in the case of lateral probe oscillation (shear force) are well reproduced by the present model. In particular, a 'clamping' effect is observed when the probe is substantially more compliant than the tuning fork. By calculating the actual probe motion along with the tuning fork response, the correct distance control operation regimes are pointed out for the shear-force case, even when using compliant probes. The model can be readily extended to the case of normal oscillation, at least for small amplitudes. Furthermore, it could be applied to a 'mixed' case of shear-force detection performed with very compliant probes. The present analysis can help to improve data interpretation and operation conditions in dynamic force microscopy and spectroscopy.

South Fork Snake River/Palisades Wildlife Mitigation Project: Environmental assessment  

SciTech Connect

BPA proposes to fund the implementation of the South Fork Snake River Programmatic Management Plan to compensate for losses of wildlife and wildlife habitat due to hydroelectric development at Palisades Dam. The Idaho Department of Fish and Game drafted the plan, which was completed in May 1993. This plan recommends land and conservation easement acquisition and wildlife habitat enhancement measures. These measures would be implemented on selected lands along the South Fork of the Snake River between Palisades Dam and the confluence with the Henry`s Fork, and on portions of the Henry`s Fork located in Bonneville, Madison, and Jefferson Counties, Idaho. BPA has prepared an Environmental Assessment evaluating the proposed project. The EA also incorporates by reference the analyses in the South Fork Snake River Activity/Operations Plan and EA prepared jointly in 1991 by the Bureau of Land Management and the Forest Service. Based on the analysis in the EA, BPA has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an Environmental Impact Statement (EIS) is not required and BPA is issuing this FONSI.

Blocked replication forks often need to be processed by recombination proteins prior to replication restart. In Escherichia coli, the UvrD repair helicase was recently shown to act at inactivated replication forks, where it counteracts a deleterious action of RecA. Using two mutants affected for different subunits of the polymerase III holoenzyme (Pol IIIh), we show here that the anti-RecA action of UvrD at blocked forks reflects two different activities of this enzyme. A defective UvrD mutant is able to antagonize RecA in cells affected for the Pol IIIh catalytic subunit DnaE. In this mutant, RecA action at blocked forks specifically requires the protein RarA (MgsA). We propose that UvrD prevents RecA binding, possibly by counteracting RarA. In contrast, at forks affected for the Pol IIIh clamp (DnaN), RarA is not required for RecA binding and the ATPase function of UvrD is essential to counteract RecA, supporting the idea that UvrD removes RecA from DNA. UvrD action on RecA is conserved in evolution as it can be performed in E. coli by the UvrD homologue from Bacillus subtilis, PcrA. PMID:17641684

NSDL National Science Digital Library

The Minnesota Historical Society's new Photograph Collection Database provides information that previously could only be obtained by travelling to MHS and consulting a card file. Yet the site simultaneously illustrates that although the number of historical images on the Web is growing steadily, these images are certainly not all online. The Photograph Collection database contains records for 44,000 individual photographs, approximately ten percent accompanied by digital images. This is less than one-fifth of the quarter of a million photographs owned by MHS. The strength of the database is its coverage of Minnesotans' lives, landscapes, leisure activities, and occupations from 1850 to the present. Try searching for "frontier and pioneer life" or "farming" to see some greatest hits from the MHS photograph collection.

Dissolution chemistry of Minnesota Lunar Simulant  

NASA Astrophysics Data System (ADS)

Dissolution studies of Minnesota Lunar Simulant (MLS), a prepared finely ground basalt, were conducted to measure solution species, to assess the levels of plant nutrients and toxic elements, and to identify minerals controlling these levels. Many of the plant nutrients in the MLS solution (Mg, S, K, Ca, Cl, Mo, P, B, Ni, and Cu) are found to be in concentrations acceptable for plant growth. Nitrogen and manganese, however, are found to be deficient, and extractable iron and zinc are marginal after 150 d. The solution concentrations of metals are several orders of magnitude below levels that are toxic to plants. Aluminum hydroxide, calcite, and clinoenstatite are found to be the most likely mineral controls for aluminum, calcium, and magnesium, respectively. Many of the methods employed can be used to study actual lunar regolith.

222Rn variations in Mystery Cave, Minnesota  

USGS Publications Warehouse

222Rn concentrations and meteorological parameters were measured at 4- h intervals over a 2-y period in Mystery Cave, southeastern Minnesota. Continuous radon monitors and meteorological sensors connected to data loggers were installed at several locations along commercial tour routes. 222Rn concentrations ranged as high as 25 kBq m-3 in summer and 20 kBq m-3 in winter. Average winter concentrations were lower than summer by at least a factor of two. Seasonal radon variations were correlative with outside air temperatures. During the winter, radon concentrations were observed to fluctuate periodically by factors of 20 or more in under 24 h. Both the long- and short-term variations are correlative with temperature- induced mixing of cave air with surface air.

Satellite inventory of Minnesota forest resources  

NASA Technical Reports Server (NTRS)

The methods and results of using Landsat Thematic Mapper (TM) data to classify and estimate the acreage of forest covertypes in northeastern Minnesota are described. Portions of six TM scenes covering five counties with a total area of 14,679 square miles were classified into six forest and five nonforest classes. The approach involved the integration of cluster sampling, image processing, and estimation. Using cluster sampling, 343 plots, each 88 acres in size, were photo interpreted and field mapped as a source of reference data for classifier training and calibration of the TM data classifications. Classification accuracies of up to 75 percent were achieved; most misclassification was between similar or related classes. An inverse method of calibration, based on the error rates obtained from the classifications of the cluster plots, was used to adjust the classification class proportions for classification errors. The resulting area estimates for total forest land in the five-county area were within 3 percent of the estimate made independently by the USDA Forest Service. Area estimates for conifer and hardwood forest types were within 0.8 and 6.0 percent respectively, of the Forest Service estimates. A trial of a second method of estimating the same classes as the Forest Service resulted in standard errors of 0.002 to 0.015. A study of the use of multidate TM data for change detection showed that forest canopy depletion, canopy increment, and no change could be identified with greater than 90 percent accuracy. The project results have been the basis for the Minnesota Department of Natural Resources and the Forest Service to define and begin to implement an annual system of forest inventory which utilizes Landsat TM data to detect changes in forest cover.

Sinkhole hazard assessment in Minnesota using a decision tree model  

NASA Astrophysics Data System (ADS)

An understanding of what influences sinkhole formation and the ability to accurately predict sinkhole hazards is critical to environmental management efforts in the karst lands of southeastern Minnesota. Based on the distribution of distances to the nearest sinkhole, sinkhole density, bedrock geology and depth to bedrock in southeastern Minnesota and northwestern Iowa, a decision tree model has been developed to construct maps of sinkhole probability in Minnesota. The decision tree model was converted as cartographic models and implemented in ArcGIS to create a preliminary sinkhole probability map in Goodhue, Wabasha, Olmsted, Fillmore, and Mower Counties. This model quantifies bedrock geology, depth to bedrock, sinkhole density, and neighborhood effects in southeastern Minnesota but excludes potential controlling factors such as structural control, topographic settings, human activities and land-use. The sinkhole probability map needs to be verified and updated as more sinkholes are mapped and more information about sinkhole formation is obtained.

The coefficient of the voltage induced frequency shift measurement on a quartz tuning fork.  

PubMed

We have measured the coefficient of the voltage induced frequency shift (VIFS) of a 32.768 KHz quartz tuning fork. Three vibration modes were studied: one prong oscillating, two prongs oscillating in the same direction, and two prongs oscillating in opposite directions. They all showed a parabolic dependence of the eigen-frequency shift on the bias voltage applied across the fork, due to the voltage-induced internal stress, which varies as the fork oscillates. The average coefficient of the VIFS effect is as low as several hundred nano-Hz per millivolt, implying that fast-response voltage-controlled oscillators and phase-locked loops with nano-Hz resolution can be built.

RecD2 Helicase Limits Replication Fork Stress in Bacillus subtilis  

PubMed Central

DNA helicases have important roles in genome maintenance. The RecD helicase has been well studied as a component of the heterotrimeric RecBCD helicase-nuclease enzyme important for double-strand break repair in Escherichia coli. Interestingly, many bacteria lack RecBC and instead contain a RecD2 helicase, which is not known to function as part of a larger complex. Depending on the organism studied, RecD2 has been shown to provide resistance to a broad range of DNA-damaging agents while also contributing to mismatch repair (MMR). Here we investigated the importance of Bacillus subtilis RecD2 helicase to genome integrity. We show that deletion of recD2 confers a modest increase in the spontaneous mutation rate and that the mutational signature in ?recD2 cells is not consistent with an MMR defect, indicating a new function for RecD2 in B. subtilis. To further characterize the role of RecD2, we tested the deletion strain for sensitivity to DNA-damaging agents. We found that loss of RecD2 in B. subtilis sensitized cells to several DNA-damaging agents that can block or impair replication fork movement. Measurement of replication fork progression in vivo showed that forks collapse more frequently in ?recD2 cells, supporting the hypothesis that RecD2 is important for normal replication fork progression. Biochemical characterization of B. subtilis RecD2 showed that it is a 5?-3? helicase and that it directly binds single-stranded DNA binding protein. Together, our results highlight novel roles for RecD2 in DNA replication which help to maintain replication fork integrity during normal growth and when forks encounter DNA damage. PMID:24443534

Wolf body mass cline across Minnesota related to taxonomy?

Recent genetic studies suggest that in northern Minnesota two species of wolves (Canis lupus L., 1758 or western wolf and Canis lycaon Schreber, 1775 (= Canis rufus Audubon and Bachman, 1851) or eastern wolf) meet and hybridize. However, little morphological information is available about these two types of wolves in Minnesota. We analyzed the mass of 950 female wolves and 1006 males older than 1 year from across northern Minnesota and found that it increased from 26.30 ?? 0.56 kg (mean ?? SE) for females and 30.60 ?? 0.72 kg for males in northeastern Minnesota to 30.01 ?? 0.43 kg for females and 35.94 ?? 0.45 kg for males in northwestern Minnesota (females: r2 = 0.79, P < 0.02; males: r2 = 0.63, P = 0.06). These mass differences add morphological information to the identities of eastern and western wolves and support the view that ranges of the two species meet in Minnesota. ?? 2008 NRC.

Fluvial sediment in Salem Fork watershed, West Virginia  

USGS Publications Warehouse

Suspended sediment discharged from the 8.32-square-mile Salem Fork study area in Harrison County, W. Va., averaged 3,500 tons per year during the first 4-year period of investigation and 1,770 tons per year during the second 4-year period. The difference as attributed to increased flow control, effected by the completion of detention structures and other conservation measures, the absence of appreciable sediment-producing construction activities, and a reduction of the amounts of rainfall and runoff during the second 4-year period. Particle-size distribution of the suspended sediment discharged from the watershed remained unchanged during the two 4-year periods. Although sand and some silt were deposited in upstream reservoirs, sands and other sediments were evidently entrained in the flow below the reservoirs. During the 7.75-year period, reservoir 11A had a trap efficiency of 88 percent. The average annual sediment yield of subwatershed 11A was 1.31 tons per acre, or 837 tons per square mile. Outflow from reservoir 11A occurred during 81 percent of the investigation 'period, October 1954 to June 1962, and 78 percent of the sediment discharge from the reservoir occurred during less than 6 percent of the investigation period. A comparison of particle-size distribution of inflow sediment with that of outflow sediment revealed that practically all sands and some silts entering reservoir 11A were deposited in the reservoir. Chemical analyses of inflow water and the particle-size analyses suggested that flocculation of fine sediments occurred in the reservoir. Analysis of the sediment data collected at the outflow of reservoir 9 during 1956-62 revealed that the average annual sediment discharge was 128,000 pounds per year. Limited particle-size data suggested that practically no sand was discharged from reservoir 9, even though the inflow contained sand. Average annual inflow to reservoirs 11A and 9 compared favorably with average annual runoff for the entire watershed-study area.

Endonuclease cleavage of blocked replication forks: An indirect pathway of DNA damage from antitumor drug-topoisomerase complexes  

NASA Astrophysics Data System (ADS)

The cytotoxicity of several important antitumor drugs depends on formation of the covalent topoisomerase-DNA cleavage complex. However, cellular processes such as DNA replication are necessary to convert the cleavage complex into a cytotoxic lesion, but the molecular mechanism of this conversion and the precise nature of the cytotoxic lesion are unknown. Using a bacteriophage T4 model system, we have previously shown that antitumor drug-induced cleavage complexes block replication forks in vivo. In this report, we show that these blocked forks can be cleaved by T4 endonuclease VII to create overt DNA breaks. The accumulation of blocked forks increased in endonuclease VII-deficient infections, suggesting that endonuclease cleavage contributes to fork processing in vivo. Furthermore, purified endonuclease VII cleaved the blocked forks in vitro close to the branch points. These results suggest that an indirect pathway of branched-DNA cleavage contributes to the cytotoxicity of antitumor drugs that target DNA topoisomerases.

Biomass of shrub - dominated wetlands in Minnesota  

SciTech Connect

Aboveground-shrub biomass was estimated in 34 shrub-dominated wetlands in northern Minnesota, representing a range of stocking. Salix was dominant in most wetlands, although a few were dominated by Alnus rugosa and Betula pumila. Shrub biomass ranged from 0.5 to 71.5 Mg/ha with an arithmetic mean of 11.2 Mg/ha. Biomass was distributed lognormally among the wetlands, with a geometric mean of 6.9 Mg/ha. Biomass estimates within wetlands had high uncertainty (10 to 85 percent of the mean) because of both clumpy distribution and large differences in size of shrubs. Eighty percent of the stands were on organic soils (Histosols), with two-thirds on minerotrophic and the remainder on weakly minerotrophic peatlands. Relationships of biomass to basal area and age were statistically significant. Differences in biomass were compared among wetlands grouped by soil or water chemistry. Stand age was a statistically significant covariate, but almost no significant differences in biomass were found among groups based on either criteria. Biomass of the shrubs in these wetlands was about four-fold greater than shrub biomass in mature forests in the area, but only slightly more than 5 percent of total biomass in those forests. These natural stands can be considered to set minimum boundary conditions for biomass production from wetlands. 20 references.

Personal networks and private forestry in Minnesota.  

PubMed

Personal networks affect the flow information and behavior through social groups. We investigated the role of personal relationships in the flow of information and adoption of sustainable forest management behavior by private forest landowners. Among the 1767 owners of 20 or more acres of Minnesota forest land surveyed, 90% have received forestry information from at least one source including 65% from a peer and 53% from a professional forester. Forestry information personal network size ranged from 0 to 14 with a mean of 2.92. Network diversity, expressed as the number of different types of information sources within the network, was relatively high relative to network size, suggesting that most landowners value diverse perspectives, despite reporting fairly small networks. Larger acreage owners, management plan holders, and frequent visitors to their forest land had significantly larger and more diverse networks. Network size and diversity were statistically unrelated to ownership tenure, landowner age, and resident/absentee status. Significantly more respondents named a peer or a professional as their most helpful source than other source categories. Satisfaction with forestry information networks was positively associated with network size and diversity, further suggesting that landowners prefer information from a variety of different sources. The results suggest that landowner education designed to foster peer learning and relationship building between landowners, foresters, loggers, and other groups may promote adoption of sustainable forest management practices.

Natural fracture analysis related to depositional environment and strain variability in the middle and upper Williams Fork Formation, Piceance Basin, Colorado  

NASA Astrophysics Data System (ADS)

As Americans continue to focus on the use of cleaner, and more efficient forms of energy, tight gas reservoirs like those in the Piceance Basin in Colorado are becoming increasingly important. The Williams Fork Formation is potentially capable of 1.2 BCF/day of natural gas production. With continued tight gas development in the Piceance Basin, and a better understanding on the controls behind zones of enhanced production, that contribution can be expected to grow. The understanding of natural fracture networks, and the drive to exploit their characteristics as migration pathways, will allow for more efficient gas production. Laramide east-west compression resulted in the formation of regional sub parallel fracture networks within the Williams Fork Formation. Major and minor localized deformation resulted in the development of structurally derived fracture networks. At least three separate sets of fractures exist at outcrop, but the extent of these networks across different preserved depositional environments is poorly constrained. Regional compressive stress directions were the primary control on fracture orientation. However, localized structures related to the Laramide deformation developed structural networks of extensional fractures that are orientated parallel to the axial trace of folds, and strike of normal faults. These locally derived structurally related networks in addition to the regional networks form overall tighter fracture spacing than bedding in lesser deformed portions of the Piceance Basin. Increased local deformation is associated with both normal surface faulting in the western Piceance Basin, and subsurface intrabasin imbricated thrust faults in the southern Grand Hogback area. Additionally, the depositional environment of a single bed controlled bed thickness and brittleness. Tighter average fracture spacing is associated with thinner, more brittle beds.

FEN1 Ensures Telomere Stability by Facilitating Replication Fork Re-initiation*  

PubMed Central

Telomeres are terminal repetitive DNA sequences whose stability requires the coordinated actions of telomere-binding proteins and the DNA replication and repair machinery. Recently, we demonstrated that the DNA replication and repair protein Flap endonuclease 1 (FEN1) is required for replication of lagging strand telomeres. Here, we demonstrate for the first time that FEN1 is required for efficient re-initiation of stalled replication forks. At the telomere, we find that FEN1 depletion results in replicative stress as evidenced by fragile telomere expression and sister telomere loss. We show that FEN1 participation in Okazaki fragment processing is not required for efficient telomere replication. Instead we find that FEN1 gap endonuclease activity, which processes DNA structures resembling stalled replication forks, and the FEN1 interaction with the RecQ helicases are vital for telomere stability. Finally, we find that FEN1 depletion neither impacts cell cycle progression nor in vitro DNA replication through non-telomeric sequences. Our finding that FEN1 is required for efficient replication fork re-initiation strongly suggests that the fragile telomere expression and sister telomere losses observed upon FEN1 depletion are the direct result of replication fork collapse. Together, these findings suggest that other nucleases compensate for FEN1 loss throughout the genome during DNA replication but fail to do so at the telomere. We propose that FEN1 maintains stable telomeres by facilitating replication through the G-rich lagging strand telomere, thereby ensuring high fidelity telomere replication. PMID:20551483

PubMed

Telomeres are terminal repetitive DNA sequences whose stability requires the coordinated actions of telomere-binding proteins and the DNA replication and repair machinery. Recently, we demonstrated that the DNA replication and repair protein Flap endonuclease 1 (FEN1) is required for replication of lagging strand telomeres. Here, we demonstrate for the first time that FEN1 is required for efficient re-initiation of stalled replication forks. At the telomere, we find that FEN1 depletion results in replicative stress as evidenced by fragile telomere expression and sister telomere loss. We show that FEN1 participation in Okazaki fragment processing is not required for efficient telomere replication. Instead we find that FEN1 gap endonuclease activity, which processes DNA structures resembling stalled replication forks, and the FEN1 interaction with the RecQ helicases are vital for telomere stability. Finally, we find that FEN1 depletion neither impacts cell cycle progression nor in vitro DNA replication through non-telomeric sequences. Our finding that FEN1 is required for efficient replication fork re-initiation strongly suggests that the fragile telomere expression and sister telomere losses observed upon FEN1 depletion are the direct result of replication fork collapse. Together, these findings suggest that other nucleases compensate for FEN1 loss throughout the genome during DNA replication but fail to do so at the telomere. We propose that FEN1 maintains stable telomeres by facilitating replication through the G-rich lagging strand telomere, thereby ensuring high fidelity telomere replication. PMID:20551483

Protein–DNA complexes are the primary sources of replication fork pausing in Escherichia coli  

PubMed Central

Replication fork pausing drives genome instability, because any loss of paused replisome activity creates a requirement for reloading of the replication machinery, a potentially mutagenic process. Despite this importance, the relative contributions to fork pausing of different replicative barriers remain unknown. We show here that Deinococcus radiodurans RecD2 helicase inactivates Escherichia coli replisomes that are paused but still functional in vitro, preventing continued fork movement upon barrier removal or bypass, but does not inactivate elongating forks. Using RecD2 to probe replisome pausing in vivo, we demonstrate that most pausing events do not lead to replisome inactivation, that transcription complexes are the primary sources of this pausing, and that an accessory replicative helicase is critical for minimizing the frequency and/or duration of replisome pauses. These findings reveal the hidden potential for replisome inactivation, and hence genome instability, inside cells. They also demonstrate that efficient chromosome duplication requires mechanisms that aid resumption of replication by paused replisomes, especially those halted by protein–DNA barriers such as transcription complexes.

Rad51 replication fork recruitment is required for DNA damage tolerance  

PubMed Central

Homologous recombination (HR) is essential for genome integrity. Recombination proteins participate in tolerating DNA lesions that interfere with DNA replication, but can also generate toxic recombination intermediates and genetic instability when they are not properly regulated. Here, we have studied the role of the recombination proteins Rad51 and Rad52 at replication forks and replicative DNA lesions. We show that Rad52 loads Rad51 onto unperturbed replication forks, where they facilitate replication of alkylated DNA by non-repair functions. The recruitment of Rad52 and Rad51 to chromatin during DNA replication is a prerequisite for the repair of the non-DSB DNA lesions, presumably single-stranded DNA gaps, which are generated during the replication of alkylated DNA. We also show that the repair of these lesions requires CDK1 and is not coupled to the fork but rather restricted to G2/M by the replicative checkpoint. We propose a new scenario for HR where Rad52 and Rad51 are recruited to the fork to promote DNA damage tolerance by distinct and cell cycle-regulated replicative and repair functions. PMID:23563117

Replication fork collisions cause pathological chromosomal amplification in cells lacking RecG DNA translocase.  

PubMed

Duplication and transmission of chromosomes require precise control of chromosome replication and segregation. Here we present evidence that RecG is a major factor influencing these processes in bacteria. We show that the extensive DnaA-independent stable DNA replication observed without RecG can lead to replication of any area of the chromosome. This replication is further elevated following irradiation with UV light and appears to be perpetuated by secondary events that continue long after the elimination of UV lesions. The resulting pathological cascade is associated with an increased number of replication forks traversing the chromosome, sometimes with extensive regional amplification of the chromosome, and with the accumulation of highly branched DNA intermediates containing few Holliday junctions. We propose that the cascade is triggered by replication fork collisions that generate 3' single-strand DNA flaps, providing sites for PriA to initiate re-replication of the DNA and thus to generate linear duplexes that provoke recombination, allowing priming of even further replication. Our results shed light on why termination of replication in bacteria is normally limited to a single encounter of two forks and carefully orchestrated within a restricted area, and explain how a system of multiple forks and random termination can operate in eukaryotes.

Smc5/6 maintains stalled replication forks in a recombination-competent conformation  

PubMed Central

The Smc5/6 structural maintenance of chromosomes complex is required for efficient homologous recombination (HR). Defects in Smc5/6 result in chromosome mis-segregation and fragmentation. By characterising two Schizosaccharomyces pombe smc6 mutants, we define two separate functions for Smc5/6 in HR. The first represents the previously described defect in processing recombination-dependent DNA intermediates when replication forks collapse, which leads to increased rDNA recombination. The second novel function defines Smc5/6 as a positive regulator of recombination in the rDNA and correlates mechanistically with a requirement to load RPA and Rad52 onto chromatin genome-wide when replication forks are stably stalled by nucleotide depletion. Rad52 is required for all HR repair, but Rad52 loading in response to replication fork stalling is unexpected and does not correlate with damage-induced foci. We propose that Smc5/6 is required to maintain stalled forks in a stable recombination-competent conformation primed for replication restart. PMID:19158664

Mus81 is essential for sister chromatid recombination at broken replication forks  

PubMed Central

Recombination is essential for the recovery of stalled/collapsed replication forks and therefore for the maintenance of genomic stability. The situation becomes critical when the replication fork collides with an unrepaired single-strand break and converts it into a one-ended double-strand break. We show in fission yeast that a unique broken replication fork requires the homologous recombination (HR) enzymes for cell viability. Two structure-specific heterodimeric endonucleases participate in two different resolution pathways. Mus81/Eme1 is essential when the sister chromatid is used for repair; conversely, Swi9/Swi10 is essential when an ectopic sequence is used for repair. Consequently, the utilization of these two HR modes of resolution mainly relies on the ratio of unique and repeated sequences present in various eukaryotic genomes. We also provide molecular evidence for sister recombination intermediates. These findings demonstrate that Mus81/Eme1 is the dedicated endonuclease that resolves sister chromatid recombination intermediates during the repair of broken replication forks. PMID:18388861

Mechanism of chromosomal DNA replication initiation and replication fork stabilization in eukaryotes.  

PubMed

Chromosomal DNA replication is one of the central biological events occurring inside cells. Due to its large size, the replication of genomic DNA in eukaryotes initiates at hundreds to tens of thousands of sites called DNA origins so that the replication could be completed in a limited time. Further, eukaryotic DNA replication is sophisticatedly regulated, and this regulation guarantees that each origin fires once per S phase and each segment of DNA gets duplication also once per cell cycle. The first step of replication initiation is the assembly of pre-replication complex (pre-RC). Since 1973, four proteins, Cdc6/Cdc18, MCM, ORC and Cdt1, have been extensively studied and proved to be pre-RC components. Recently, a novel pre-RC component called Sap1/Girdin was identified. Sap1/Girdin is required for loading Cdc18/Cdc6 to origins for pre-RC assembly in the fission yeast and human cells, respectively. At the transition of G1 to S phase, pre-RC is activated by the two kinases, cyclindependent kinase (CDK) and Dbf4-dependent kinase (DDK), and subsequently, RPA, primase-pol?, PCNA, topoisomerase, Cdc45, pol?, and pol? are recruited to DNA origins for creating two bi-directional replication forks and initiating DNA replication. As replication forks move along chromatin DNA, they frequently stall due to the presence of a great number of replication barriers on chromatin DNA, such as secondary DNA structures, protein/DNA complexes, DNA lesions, gene transcription. Stalled forks must require checkpoint regulation for their stabilization. Otherwise, stalled forks will collapse, which results in incomplete DNA replication and genomic instability. This short review gives a concise introduction regarding the current understanding of replication initiation and replication fork stabilization. PMID:24699916

Simple force balance accelerometer/seismometer based on a tuning fork displacement sensor  

SciTech Connect

Seismometers and microelectromechanical system accelerometers use the force-balance principle to obtain measurements. In these instruments the displacement of a mass object by an unknown force is sensed using a very high-resolution displacement sensor. The position of the object is then stabilized by applying an equal and opposite force to it. The magnitude of the stabilizing force is easily measured, and is assumed to be equivalent to the unknown force. These systems are critically dependent on the displacement sensor. In this article we use a resonant quartz tuning fork as the sensor. The tuning fork is operated so that its oscillation is lightly damped by the proximity of the movable mass object. Changes in the position of the mass object cause changes in the phase of the fork's resonance; this is used as the feedback variable in controlling the mass position. We have developed an acceleration sensor using this principle. The mass object is a piezoelectric bimorph diaphragm which is anchored around its perimeter, allowing direct electronic control of the displacement of its center. The tuning fork is brought very close to the diaphragm center, and is connected into a self-oscillating feedback circuit which has phase and amplitude as outputs. The diaphragm position is adjusted by a feedback loop, using phase as the feedback variable, to keep it in a constant position with respect to the tuning fork. The measured noise for this sensor is approximately 10.0 mg in a bandwidth of 100 Hz, which is substantially better than commercial systems of equivalent cost and size.

Dissolved-Solids Load in Henrys Fork Upstream from the Confluence with Antelope Wash, Wyoming, Water Years 1970-2009  

USGS Publications Warehouse

Annual dissolved-solids load at the mouth of Henrys Fork was estimated by using data from U.S. Geological Survey streamflow-gaging station 09229500, Henrys Fork near Manila, Utah. The annual dissolved-solids load for water years 1970-2009 ranged from 18,300 tons in 1977 to 123,300 tons in 1983. Annual streamflows for this period ranged from 14,100 acre-feet in 1977 to 197,500 acre-feet in 1983. The 25-percent trimmed mean dissolved-solids load for water years 1970-2009 was 44,300 tons per year at Henrys Fork near Manila, Utah. Previous simulations using a SPAtially Referenced Regression On Watershed attributes (SPARROW) model for dissolved solids specific to water year 1991 conditions in the Upper Colorado River Basin predicted an annual dissolved-solids load of 25,000 tons for the Henrys Fork Basin upstream from Antelope Wash. On the basis of computed dissolved-solids load data from Henrys Fork near Manila, Utah, together with estimated annual dissolved-solids load from Antelope Wash and Peoples Canal, this prediction was adjusted to 37,200 tons. As determined by simulations with the Upper Colorado River Basin SPARROW model, approximately 56 percent (14,000 tons per year) of the dissolved-solids load at Henrys Fork upstream from Antelope Wash is associated with the 21,500 acres of irrigated agricultural lands in the upper Henrys Fork Basin.

The Economic Impact of Exposure to Secondhand Smoke in Minnesota  

PubMed Central

Objectives. Using the risk categories established by the 2006 US surgeon general's report, we estimated medical treatment costs related to exposure to secondhand tobacco smoke (SHS) in the state of Minnesota. Methods. We estimated the prevalence and costs of treated medical conditions related to SHS exposure in 2003 with data from Blue Cross and Blue Shield (Minnesota's largest insurer), the Current Population Survey, and population attributable risk estimates for these conditions reported in the scientific literature. We adjusted treatment costs to the state level by health insurance category by using the Medical Expenditure Panel Survey. Results. The total annual cost of treatment in Minnesota for conditions for which the 2006 surgeon general's report found sufficient evidence to conclude a causal link with exposure to SHS was $228.7 million in 2008 dollars—equivalent to $44.58 per Minnesota resident. Sensitivity analyses showed a range from $152.1 million to $330.0 million. Conclusions. The results present a strong rationale for regulating smoking in public places and were used to support the passage of Minnesota's Freedom to Breathe Act of 2007. PMID:19197082

Cancer mortality in agricultural regions of Minnesota.  

PubMed Central

Because of its unique geology, Minnesota can be divided into four agricultural regions: south-central region one (corn, soybeans); west-central region two (wheat, corn, soybeans); northwest region three (wheat, sugar beets, potatoes); and northeast region four (forested and urban in character). Cancer mortality (1980-1989) in agricultural regions one, two, and three was compared to region four. Using data compiled by the National Center for Health Statistics, cancer mortality was summarized by 5-year age groups, sex, race, and county. Age-standardized mortality rate ratios were calculated for white males and females for all ages combined, and for children aged 0-14. Increased mortality rate ratios and 95% confidence intervals (CIs) were observed for the following cancer sites: region one--lip (men), standardized rate ratio (SRR) = 2.70 (CI, 1.08-6.71); nasopharynx (women), SRR = 3.35 (CI, 1.20-9.31); region two--non-Hodgkin's lymphoma (women), SRR = 1.35 (CI, 1.09-1.66); and region three--prostate (men), SRR = 1.12 (CI, 1.00-1.26); thyroid (men), SRR = 2.95 (CI, 1.35-6.44); bone (men), SRR = 2.09 (CI, 1. 00-4.34); eye (women), SRR = 5.77 (CI, 1.90-17.50). Deficits of smoking-related cancers were noted. Excess cancers reported are consistent with earlier reports of agriculturally related cancers in the midwestern United States. However, reports on thyroid and bone cancer in association with agricultural pesticides are few in number. The highest use of fungicides occurs in region three. Ethylenebisdithiocarbamates, whose metabolite is a known cause of thyroid cancer in rats, are frequently applied. This report provides a rationale for evaluation of the carcinogenic potential of this suspect agent in humans. Images Figure 1 PMID:10064550

Parameters of tip-sample interactions in shear mode using a quartz tuning fork AFM with controllable Q-factor  

NASA Astrophysics Data System (ADS)

A quartz tuning fork-based atomic force microscopy for investigating the tip-sample interactions at the nanoscale in the shear-force mode is described. Results of force interactions (damping and elastic forces) can be obtained from the amplitude-phase-distance spectroscopy measurements made with a tuning fork with a tungsten tip and a sample surface. The influence of the interaction between tip and sample using the quality factor as an indicator is investigated. Furthermore, a simple model shows that the extension of a tuning fork-based AFM can be applied to quantitative analysis of the properties of the sample surface.

Pregnancy and birth in Minnesota's Hmong population: changing practices.  

PubMed

The arrival of the Hmong in Minnesota starting in the late 1970s brought many challenges to both an ancient way of life as well as to hospitals and clinics trying to care for these new refugees. For Hmong women who were new to the United States, their first encounter with the U.S. health care system was often during pregnancy and birth. This article summarizes how some of the perinatal practices of the Hmong evolved following their arrival in Minnesota as well as how providers adapted in order to provide their Hmong patients with culturally sensitive care.

Saccharomyces cerevisiae Rrm3p DNA Helicase Promotes Genome Integrity by Preventing Replication Fork Stalling: Viability of rrm3 Cells Requires the Intra-S-Phase Checkpoint and Fork Restart Activities  

Microsoft Academic Search

Rrm3p is a 5-to-3 DNA helicase that helps replication forks traverse protein-DNA complexes. Its absence leads to increased fork stalling and breakage at over 1,000 specific sites located throughout the Saccharomyces cerevisiae genome. To understand the mechanisms that respond to and repair rrm3-dependent lesions, we carried out a candidate gene deletion analysis to identify genes whose mutation conferred slow growth

A Distinct Replication Fork Protection Pathway Connects Fanconi Anemia Tumor Suppressors to RAD51-BRCA1/2  

PubMed Central

SUMMARY Genes mutated in patients with Fanconi anemia (FA) interact with the DNA repair genes BRCA1 and BRCA2/FANCD1 to suppress tumorigenesis, but the molecular functions ascribed to them cannot fully explain all of their cellular roles. Here, we show a repair-independent requirement for FA genes, including FANCD2, and BRCA1 in protecting stalled replication forks from degradation. Fork protection is surprisingly rescued in FANCD2-deficient cells by elevated RAD51 levels or stabilized RAD51 filaments. Moreover, FANCD2-mediated fork protection is epistatic with RAD51 functions, revealing an unanticipated fork protection pathway that connects FA genes to RAD51 and the BRCA1/2 breast cancer suppressors. Collective results imply a unified molecular mechanism for repair-independent functions of FA, RAD51, and BRCA1/2 proteins in preventing genomic instability and suppressing tumorigenesis.

Calibration of piezoelectric positioning actuators using a reference voltage-to-displacement transducer based on quartz tuning forks  

E-print Network

We use a piezoelectric quartz tuning fork to calibrate the displacement of ceramic piezoelectric scanners which are widely employed in scanning probe microscopy. We measure the static piezoelectric response of a quartz tuning fork and find it to be highly linear, non-hysteretic and with negligible creep. These performance characteristics, close to those of an ideal transducer, make quartz transducers superior to ceramic piezoelectric actuators. Furthermore, quartz actuators in the form of a tuning fork have the advantage of yielding static displacements comparable to those of local probe microscope scanners. We use the static displacement of a quartz tuning fork as a reference to calibrate the three axis displacement of a ceramic piezoelectric scanner. Although this calibration technique is a non-traceable method, it can be more versatile than using calibration grids because it enables to characterize the linear and non-linear response of a piezoelectric scanner in a broad range of displacements, spanning fro...

FANCD2-Controlled Chromatin Access of the Fanconi-Associated Nuclease FAN1 Is Crucial for the Recovery of Stalled Replication Forks.  

PubMed

Fanconi anemia (FA) is a cancer predisposition syndrome characterized by cellular hypersensitivity to DNA interstrand cross-links (ICLs). Within the FA pathway, an upstream core complex monoubiquitinates and recruits the FANCD2 protein to ICLs on chromatin. Ensuing DNA repair involves the Fanconi-associated nuclease 1 (FAN1), which interacts selectively with monoubiquitinated FANCD2 (FANCD2(Ub)) at ICLs. Importantly, FANCD2 has additional independent functions: it binds chromatin and coordinates the restart of aphidicolin (APH)-stalled replication forks in concert with the BLM helicase, while protecting forks from nucleolytic degradation by MRE11. We identified FAN1 as a new crucial replication fork recovery factor. FAN1 joins the BLM-FANCD2 complex following APH-mediated fork stalling in a manner dependent on MRE11 and FANCD2, followed by FAN1 nuclease-mediated fork restart. Surprisingly, APH-induced activation and chromatin recruitment of FAN1 occur independently of the FA core complex or the FAN1 UBZ domain, indicating that the FANCD2(Ub) isoform is dispensable for functional FANCD2-FAN1 cross talk during stalled fork recovery. In the absence of FANCD2, MRE11 exonuclease-promoted access of FAN1 to stalled forks results in severe FAN1-mediated nucleolytic degradation of nascent DNA strands. Thus, FAN1 nuclease activity at stalled replication forks requires tight regulation: too little inhibits fork restart, whereas too much causes fork degradation. PMID:25135477

ATM and ATR Activities Maintain Replication Fork Integrity during SV40 Chromatin Replication  

PubMed Central

Mutation of DNA damage checkpoint signaling kinases ataxia telangiectasia-mutated (ATM) or ATM- and Rad3-related (ATR) results in genomic instability disorders. However, it is not well understood how the instability observed in these syndromes relates to DNA replication/repair defects and failed checkpoint control of cell cycling. As a simple model to address this question, we have studied SV40 chromatin replication in infected cells in the presence of inhibitors of ATM and ATR activities. Two-dimensional gel electrophoresis and southern blotting of SV40 chromatin replication products reveal that ATM activity prevents accumulation of unidirectional replication products, implying that ATM promotes repair of replication-associated double strand breaks. ATR activity alleviates breakage of a functional fork as it converges with a stalled fork. The results suggest that during SV40 chromatin replication, endogenous replication stress activates ATM and ATR signaling, orchestrating the assembly of genome maintenance machinery on viral replication intermediates.

DNA polymerase ?-dependent DNA synthesis at stalled replication forks is important for CHK1 activation  

PubMed Central

Formation of primed single-stranded DNA at stalled replication forks triggers activation of the replication checkpoint signalling cascade resulting in the ATR-mediated phosphorylation of the Chk1 protein kinase, thus preventing genomic instability. By using siRNA-mediated depletion in human cells and immunodepletion and reconstitution experiments in Xenopus egg extracts, we report that the Y-family translesion (TLS) DNA polymerase kappa (Pol ?) contributes to the replication checkpoint response and is required for recovery after replication stress. We found that Pol ? is implicated in the synthesis of short DNA intermediates at stalled forks, facilitating the recruitment of the 9-1-1 checkpoint clamp. Furthermore, we show that Pol ? interacts with the Rad9 subunit of the 9-1-1 complex. Finally, we show that this novel checkpoint function of Pol ? is required for the maintenance of genomic stability and cell proliferation in unstressed human cells. PMID:23799366

Break-induced replication repair of damaged forks induces genomic duplications in human cells  

PubMed Central

In budding yeast, one-ended DNA double-strand breaks (DSBs) and damaged replication forks are repaired by break-induced replication (BIR), a homologous recombination pathway that requires the Pol32 subunit of DNA polymerase delta. DNA replication stress is prevalent in cancer, but BIR has not been characterized in mammals. In a cyclin E overexpression model of DNA replication stress, POLD3, the human ortholog of POL32, was required for cell cycle progression and processive DNA synthesis. Segmental genomic duplications induced by cyclin E overexpression were also dependent on POLD3, as were BIR-mediated recombination events captured with a specialized DSB repair assay. We propose that BIR repairs damaged replication forks in mammals, accounting for the high frequency of genomic duplications in human cancers. PMID:24310611

Architecture of the Replication Fork Stalled at the 3? End of Yeast Ribosomal Genes  

PubMed Central

Every unit of the rRNA gene cluster of Saccharomyces cerevisiae contains a unique site, termed the replication fork barrier (RFB), where progressing replication forks are stalled in a polar manner. In this work, we determined the positions of the nascent strands at the RFB at nucleotide resolution. Within an HpaI-HindIII fragment essential for the RFB, a major and two closely spaced minor arrest sites were found. In the majority of molecules, the stalled lagging strand was completely processed and the discontinuously synthesized nascent lagging strand was extended three bases farther than the continuously synthesized leading strand. A model explaining these findings is presented. Our analysis included for the first time the use of T4 endonuclease VII, an enzyme recognizing branched DNA molecules. This enzyme cleaved predominantly in the newly synthesized homologous arms, thereby specifically releasing the leading arm. PMID:10891513

Interaction of RNA polymerase II fork loop 2 with downstream non-template DNA regulates transcription elongation.  

PubMed

Fork loop 2 is a small semiconservative segment of the larger fork domain in the second largest Rpb2 subunit of RNA polymerase II (Pol II). This flexible loop, juxtaposed at the leading edge of transcription bubble, has been proposed to participate in DNA strand separation, translocation along DNA, and NTP loading to Pol II during elongation. Here we show that the Rpb2 mutant carrying a deletion of the flexible part of the loop is not lethal in yeast. The mutation exhibits no defects in DNA melting and translocation in vitro but confers a moderate decrease of the catalytic activity of the enzyme caused by the impaired sequestration of the NTP substrate in the active center prior to catalysis. In the structural model of the Pol II elongation complex, fork loop 2 directly interacts with an unpaired DNA residue in the non-template DNA strand one nucleotide ahead from the active center (the i+2 position). We showed that elimination of this putative interaction by replacement of the i+2 residue with an abasic site inhibits Pol II activity to the same degree as the deletion of fork loop 2. This replacement has no detectable effect on the activity of the mutant enzyme. We provide direct evidence that interaction of fork loop 2 with the non-template DNA strand facilitates NTP sequestration through interaction with the adjacent segment of the fork domain involved in the active center of Pol II.

Rep and PriA helicase activities prevent RecA from provoking unnecessary recombination during replication fork repair.  

PubMed

The rescue of replication forks stalled on the template DNA was investigated using an assay for synthetic lethality that provides a visual readout of cell viability and permits investigation of why certain mutations are lethal when combined. The results presented show that RecA and other recombination proteins are often engaged during replication because RecA is present and provokes recombination rather than because recombination is necessary. This occurs particularly frequently in cells lacking the helicase activities of Rep and PriA. We propose that these two proteins normally limit the loading of RecA on ssDNA regions exposed on the leading strand template of damaged forks, and do so by unwinding the nascent lagging strand, thus facilitating reannealing of the parental strands. Gap closure followed by loading of the DnaB replicative helicase enables synthesis of the leading strand to continue. Without either activity, RecA loads more frequently on the DNA and drives fork reversal, which creates a chickenfoot structure and a requirement for other recombination proteins to re-establish a viable fork. The assay also reveals that stalled transcription complexes are common impediments to fork progression, and that damaged forks often reverse independently of RecA. PMID:16882986

Replication Fork Stalling and Checkpoint Activation by a PKD1 Locus Mirror Repeat Polypurine-Polypyrimidine (Pu-Py) Tract*  

PubMed Central

DNA sequences prone to forming noncanonical structures (hairpins, triplexes, G-quadruplexes) cause DNA replication fork stalling, activate DNA damage responses, and represent hotspots of genomic instability associated with human disease. The 88-bp asymmetric polypurine-polypyrimidine (Pu-Py) mirror repeat tract from the human polycystic kidney disease (PKD1) intron 21 forms non-B DNA secondary structures in vitro. We show that the PKD1 mirror repeat also causes orientation-dependent fork stalling during replication in vitro and in vivo. When integrated alongside the c-myc replicator at an ectopic chromosomal site in the HeLa genome, the Pu-Py mirror repeat tract elicits a polar replication fork barrier. Increased replication protein A (RPA), Rad9, and ataxia telangiectasia- and Rad3-related (ATR) checkpoint protein binding near the mirror repeat sequence suggests that the DNA damage response is activated upon replication fork stalling. Moreover, the proximal c-myc origin of replication was not required to cause orientation-dependent checkpoint activation. Cells expressing the replication fork barrier display constitutive Chk1 phosphorylation and continued growth, i.e. checkpoint adaptation. Excision of the Pu-Py mirror repeat tract abrogates the DNA damage response. Adaptation to Chk1 phosphorylation in cells expressing the replication fork barrier may allow the accumulation of mutations that would otherwise be remediated by the DNA damage response.

Open Doorway to Truth: Legacy of the Minnesota Tobacco Trial  

PubMed Central

More than a decade has passed since the conclusion of the Minnesota tobacco trial and the signing of the Master Settlement Agreement (MSA) by 46 US State Attorneys General and the US tobacco industry. The Minnesota settlement exposed the tobacco industry's long history of deceptive marketing, advertising, and research and ultimately forced the industry to change its business practices. The provisions for public document disclosure that were included in the Minnesota settlement and the MSA have resulted in the release of approximately 70 million pages of documents and nearly 20,000 other media materials. No comparable dynamic, voluminous, and contemporaneous document archive exists. Only a few single events in the history of public health have had as dramatic an effect on tobacco control as the public release of the tobacco industry's previously secret internal documents. This review highlights the genesis of the release of these documents, the history of the document depositories created by the Minnesota settlement, the scientific and policy output based on the documents, and the use of the documents in furthering global public health strategies.

Histone H3.3 Is Required to Maintain Replication Fork Progression after UV Damage  

PubMed Central

Summary Unlike histone H3, which is present only in S phase, the variant histone H3.3 is expressed throughout the cell cycle [1] and is incorporated into chromatin independent of replication [2]. Recently, H3.3 has been implicated in the cellular response to ultraviolet (UV) light [3]. Here, we show that chicken DT40 cells completely lacking H3.3 are hypersensitive to UV light, a defect that epistasis analysis suggests may result from less-effective nucleotide excision repair. Unexpectedly, H3.3-deficient cells also exhibit a substantial defect in maintaining replication fork progression on UV-damaged DNA, which is independent of nucleotide excision repair, demonstrating a clear requirement for H3.3 during S phase. Both the UV hypersensitivity and replication fork slowing are reversed by expression of H3.3 and require the specific residues in the ?2 helix that are responsible for H3.3 binding its dedicated chaperones. However, expression of an H3.3 mutant in which serine 31 is replaced with alanine, the equivalent residue in H3.2, restores normal fork progression but not UV resistance, suggesting that H3.3[S31A] may be incorporated at UV-damaged forks but is unable to help cells tolerate UV lesions. Similar behavior was observed with expression of H3.3 carrying mutations at K27 and G34, which have been reported in pediatric brain cancers. We speculate that incorporation of H3.3 during replication may mark sites of lesion bypass and, possibly through an as-yet-unidentified function of the N-terminal tail, facilitate subsequent processing of the damage.

Initial Geomorphic Responses to Removal of Milltown Dam, Clark Fork River, Montana, USA  

NASA Astrophysics Data System (ADS)

The removal of Milltown Dam on the Clark Fork River, Montana, USA, is creating a field-scale experiment on upstream and downstream responses to dam removal and on how gravel-bed rivers respond to sediment pulses. Milltown Dam was removed in 2008, reconnecting the Clark Fork River to its upstream basin in terms of sediment transport and fish passage. This dam removal is especially notable because (1) it is the largest dam removal to date in the United States in terms of the volume of reservoir sediment potentially available for downstream transport (over 3 million m3; 1.7 million m3 are being mechanically removed); and (2) the dam is the downstream end of the largest Superfund site in the United States, the Clark Fork Complex, and reservoir sediments are composed largely of contaminated mine tailings. Data collection on pre- and post-dam removal channel morphology, bed sediment characteristics, and sediment loads are being used to investigate spatial and temporal patterns of sediment transport and deposition associated with this dam removal. In the first several months following breaching of the dam, snowmelt runoff with a 3-year recurrence interval peak caused substantial erosion and downstream transport of metals-laden sediments from Milltown reservoir. Reservoir sediments in the Clark Fork arm of Milltown reservoir eroded at levels far exceeding modeling predictions as a result of both incision to the new base level created by dam removal and bank retreat of over 200 m in reaches upstream of a constructed bypass reach and remediation area. Copper and other metals in these eroded reservoir sediments provide a tracer for identifying whether sediment deposits observed downstream of the dam originated from Milltown reservoir or uncontaminated tributaries and indicate that Milltown sediments have reached over 200 km downstream. Downstream deposition has been greatest along channel margins and in side-channel areas, whereas the transport capacity of the active channel has limited channel changes there.

Histone deacetylases 1 and 2 maintain S-phase chromatin and DNA replication fork progression  

PubMed Central

Background Histone deacetylases (HDACs) play a critical role in the maintenance of genome stability. Class I HDACs, histone deacetylase 1 and 2 (Hdac1 and Hdac2) are recruited to the replication fork by virtue of their interactions with the replication machinery. However, functions for Hdac1 and Hdac2 (Hdacs1,2) in DNA replication are not fully understood. Results Using genetic knockdown systems and novel Hdacs1,2-selective inhibitors, we found that loss of Hdacs1,2 leads to a reduction in the replication fork velocity, and an increase in replication stress response culminating in DNA damage. These observed defects are due to a direct role for Hdacs1,2 in DNA replication, as transcription of genes involved in replication was not affected in the absence of Hdacs1,2. We found that loss of Hdacs1,2 functions increases histone acetylation (ac) on chromatin in S-phase cells and affects nascent chromatin structure, as evidenced by the altered sensitivity of newly synthesized DNA to nuclease digestion. Specifically, H4K16ac, a histone modification involved in chromatin decompaction, is increased on nascent chromatin upon abolishing Hdacs1,2 activities. It was previously shown that H4K16ac interferes with the functions of SMARCA5, an ATP-dependent ISWI family chromatin remodeler. We found SMARCA5 also associates with nascent DNA and loss of SMARCA5 decreases replication fork velocity similar to the loss or inhibition of Hdacs1,2. Conclusions Our studies reveal important roles for Hdacs1,2 in nascent chromatin structure maintenance and regulation of SMARCA5 chromatin-remodeler function, which together are required for proper replication fork progression and genome stability in S-phase.

Burnup verification measurements at a US nuclear utility using the FORK measurement system  

SciTech Connect

The FORK measurement system, designed at Los Alamos National Laboratory (LANL) for the International Atomic Energy Agency (IAEA) safeguards program, has been used to examine spent reactor fuel assemblies at Duke Power Company`s Oconee Nuclear Station. The FORK system measures the passive neutron and gamma-ray emission from spent fuel assemblies while in the storage pool. These measurements can be correlated with burnup and cooling time, and can be used to verify the reactor site records. Verification measurements may be used to help ensure nuclear criticality safety when burnup credit is applied to spent fuel transport and storage systems. By taking into account the reduced reactivity of spent fuel due to its burnup in the reactor, burnup credit results in more efficient and economic transport and storage. The objectives of these tests are to demonstrate the applicability of the FORK system to verify reactor records and to develop optimal procedures compatible with utility operations. The test program is a cooperative effort supported by Sandia National Laboratories, the Electric Power Research Institute (EPRI), Los Alamos National Laboratory, and the Duke Power Company.

Far-travelled permian chert of the North Fork terrane, Klamath mountains, California  

USGS Publications Warehouse

Permian chert in the North Fork terrane and correlative rocks of the Klamath Mountains province has a remanent magnetization that is prefolding and presumably primary. Paleomagnetic results indicate that the chert formed at a paleolatitude of 8.6?? ?? 2.5?? but in which hemisphere remains uncertain. This finding requires that these rocks have undergone at least 8.6?? ?? 4.4?? of northward transport relative to Permian North America since their deposition. Paleontological evidence suggests that the Permian limestone of the Eastern Klamath terrane originated thousands of kilometers distant from North America. The limestone of the North Fork terrane may have formed at a similar or even greater distance as suggested by its faunal affinity to the Eastern Klamath terrane and more westerly position. Available evidence indicates that convergence of the North Fork and composite Central Metamorphic-Eastern Klamath terranes occurred during Triassic or Early Jurassic time and that their joining together was a Middle Jurassic event. Primary and secondary magnetizations indicate that the new composite terrane containing these and other rocks of the Western Paleozoic and Triassic belt behaved as a single rigid block that has been latitudinally concordant with the North American craton since Middle Jurassic time.

Strand invasion by HLTF as a mechanism for template switch in fork rescue.  

PubMed

Stalling of replication forks at unrepaired DNA lesions can result in discontinuities opposite the damage in the newly synthesized DNA strand. Translesion synthesis or facilitating the copy from the newly synthesized strand of the sister duplex by template switching can overcome such discontinuities. During template switch, a new primer-template junction has to be formed and two mechanisms, including replication fork reversal and D-loop formation have been suggested. Genetic evidence indicates a major role for yeast Rad5 in template switch and that both Rad5 and its human orthologue, Helicase-like transcription factor (HLTF), a potential tumour suppressor can facilitate replication fork reversal. This study demonstrates the ability of HLTF and Rad5 to form a D-loop without requiring ATP binding and/or hydrolysis. We also show that this strand-pairing activity is independent of RAD51 in vitro and is not mechanistically related to that of another member of the SWI/SNF family, RAD54. In addition, the 3'-end of the invading strand in the D-loop can serve as a primer and is extended by DNA polymerase. Our data indicate that HLTF is involved in a RAD51-independent D-loop branch of template switch pathway that can promote repair of gaps formed during replication of damaged DNA. PMID:24198246

Cohesin association to replication sites depends on rad50 and promotes fork restart.  

PubMed

The cohesin complex holds together newly replicated chromatids and is involved in diverse pathways that preserve genome integrity. We show that in budding yeast, cohesin is transiently recruited to active replication origins, and it spreads along DNA as forks progress. When DNA synthesis is impeded, cohesin accumulates at replication sites and is critical for the recovery of stalled forks. Cohesin enrichment at replication forks does not depend on ?H2A(X) formation, which differs from its loading requirements at DNA double-strand breaks (DSBs). However, cohesin localization is largely reduced in rad50? mutants and in cells lacking both Mec1 and Tel1 checkpoint kinases. Interestingly, cohesin loading at replication sites depends on the structural features of Rad50 that are important for bridging sister chromatids, including the CXXC hook domain and the length of the coiled-coil extensions. Together, these data reveal a function for cohesin in the maintenance of genome integrity during S phase. PMID:22885006

Processing of telomeric DNA ends requires the passage of a replication fork.  

PubMed

During telomere replication in yeast, chromosome ends acquire a long single-stranded extension of the strand making the 3' end. Previous work showed that these 3' tails are generated late in S-phase, when conventional replication is virtually complete. In addition, the extensions were also observed in cells that lacked telomerase. Therefore, a model was proposed that predicted an activity that recessed the 5' ends at yeast telomeres after conventional replication was complete. Here, we demonstrate that this processing activity is dependent on the passage of a replication fork through yeast telomeres. A non-replicating linear plasmid with telomeres at each end does not acquire single-stranded extensions, while an identical construct containing an origin of replication does. Thus, the processing activity could be associated with the enzymes at the replication fork itself, or the passage of the fork through the telomeric sequences allows a transient access for the activity to the telomeres. We therefore propose that there is a mechanistic link between the conventional replication machinery and telomere maintenance. PMID:9826760

Validation of a Monte Carlo Model of the Fork Detector with a Calibrated Neutron Source  

NASA Astrophysics Data System (ADS)

The investigation of experimental methods for safeguarding spent fuel elements is one of the research areas at the Belgian Nuclear Research Centre SCK•CEN. A version of the so-called Fork Detector has been designed at SCK•CEN and is in use at the Belgian Nuclear Power Plant of Doel for burnup determination purposes. The Fork Detector relies on passive neutron and gamma measurements for the assessment of the burnup and safeguards verification activities. In order to better evaluate and understand the method and in view to extend its capabilities, an effort to model the Fork detector was made with the code MCNPX. A validation of the model was done in the past using spent fuel measurement data. This paper reports about the measurements carried out at the Laboratory for Nuclear Calibrations (LNK) of SCK•CEN with a 252Cf source calibrated according to ISO 8529 standards. The experimental data are presented and compared with simulations. In the simulations, not only was the detector modeled but also the measurement room was taken into account based on the available design information. The results of this comparison exercise are also presented in this paper.

On bandwidth characteristics of tuning fork micro-gyroscope with mechanically coupled sense mode.  

PubMed

The bandwidth characteristics of a tuning fork micro-gyroscope with mechanically coupled sense mode were investigated in this paper to provide some references for mechanical bandwidth design. The concept of sense mode mechanical coupling is introduced first. Theoretical frequency response analyses were then carried out on the mechanical part of the gyroscope. Equations representing the relationships between the differential output signal and the frequency of the input angular rate were deduced in full frequency range and further simplified in low frequency range. Based on these equations, bandwidth characteristics under ideal and non-ideal conditions are discussed. Analytical results show that under ideal conditions, the bandwidth characteristics of a tuning fork micro-gyroscope are similar to those of a single mass micro-gyroscope, but under non-ideal conditions, especially when sense mass and/or stiffness are asymmetric, the bandwidth characteristics would be quite different because the in-phase mode would participate in the anti-phase vibration response. Experimental verifications were carried out on two micro-gyroscope prototypes designed in our laboratory. The deduced equations and analytical results can be used in guiding the mechanical bandwidth design of tuning fork micro-gyroscopes with mechanically coupled sense mode. PMID:25051030

Grand Rip and Grand Bang/Crunch cosmological singularities  

E-print Network

The present accelerated expansion of the universe has enriched the list of possible scenarios for its fate, singular or not. In this paper a unifying framework for analyzing such behaviors is proposed, based on generalized power and asymptotic expansions of the barotropic index $w$, or equivalently of the deceleration parameter $q$, in terms of the time coordinate. Besides well known singular and non-singular future behaviors, other types of strong singularities appear around the phantom divide in flat models, with features similar to those of big rip or big bang/crunch, which we have dubbed grand rip and grand bang/crunch respectively, since energy density and pressure diverge faster than $t^{-2}$ in coordinate time. In addition to this, the scale factor does not admit convergent generalized power series around these singularities with a finite number of terms with negative powers.

Late Cretaceous Middle Fork caldera and its resurgent granite porphyry intrusion, east-central Alaska  

NASA Astrophysics Data System (ADS)

Named for the Middle Fork of the North Fork of the Fortymile River, the Middle Fork caldera encompasses a 10 x 20 km area of rhyolite welded tuff and granite porphyry ~100 km west of the Yukon border. Intracaldera tuff has ?4 mm quartz and feldspar phenocrysts and cm-sized fiamme; its maximum exposed thickness is 850 m. Less densely welded tuff near the caldera margins locally contains 1-2 cm K-feldspar megacrysts and pumice clasts to 6 cm. Zircon from intracaldera tuff yields a SHRIMP-RG U-Pb age of 68.7 ± 1.1 Ma (all ages 95% confidence). Granite porphyry occupies much of an 8 x 12 km area having 650 m of relief within the western part of the caldera fill. Zircon from the porphyry gives a SHRIMP-RG U-Pb age of 68.4 ± 1.0 Ma. These ages agree with a previous 40Ar/39Ar biotite age of 69.1 ± 0.5 Ma for proximal outflow tuff. The crystal-rich intracaldera tuff contains embayed quartz, plagioclase>K-feldspar, biotite, and Fe-Ti oxide phenocrysts in a very fine-grained crystalline groundmass. The porphyry carries 40-50% of larger phenocrysts of the same phases (skeletal quartz to 1 cm; K-feldspar to 2 cm, rarely to 4 cm) in a fine-grained groundmass characterized by abundant 50-100 ?m quartz. Compositions of 3 tuff and 3 porphyry samples overlap, form a limited differentiation series at 69-72% SiO2, have arc geochemical signatures, and yield subparallel chondrite-normalized rare earth element patterns with light REE enrichment, concave-upward heavy REE, and small negative Eu anomalies. Although their phenocrysts differ in size (owing to fragmentation of crystals in the tuff) and abundance, the similar mineralogy, composition (in spite of crystal concentration in the tuff), and indistinguishable ages of the tuff and porphyry indicate that the magmas were closely related. A rare magmatic enclave (54% SiO2, arc geochemical signature) in the porphyry may be similar to parental magma and provides evidence of mafic magma and thermal input. The porphyry is interpreted to have been exposed by erosion of thick intracaldera tuff from an asymmetric resurgent dome. The Middle Fork of the North Fork of the Fortymile River cuts an arcuate valley into and around the caldera on the west and north, and may have cut down from an original caldera moat. Proximal outflow tuff, and thus the 69 Ma land surface, remains at the west margin of the caldera structure. The Middle Fork caldera lies within a region of Paleozoic metamorphic rocks and Mesozoic plutons bounded by northeast-trending faults. To the northwest, Cretaceous plutonic rocks are widely exposed, indicating greater exhumation. The Middle Fork is a relatively well preserved caldera within a broad region of Alaska and adjacent Yukon that contains Late Cretaceous plutons and, in the less deeply exhumed blocks, silicic volcanic rocks.

Hydrology of the North Fork of the Right Fork of Miller Creek, Carbon County, Utah, before, during, and after underground coal mining  

USGS Publications Warehouse

From 1988-92 the U.S. Geological Survey, in cooperation with the Utah Division of Oil, Gas, and Mining, studied the effects of underground coal mining and the resulting subsidence on the hydrologic system near the North Fork of the Right Fork of Miller Creek, Carbon County, Utah. The subsidence caused open fractures at land surface, debris slides, and rockfalls in the canyon above the mined area. Land surface subsided and moved several feet horizontally. The perennial stream and a tributary upstream from the mined area were diverted below the ground by surface fractures where the overburden thickness above the Wattis coal seam is 300 to 500 feet. The reach downstream was dry but flow resumed where the channel traversed the Star Point Sandstone, which forms the aquifer below the coal seams where ground-water discharge provides new base flow. Concentrations of dissolved constituents in the stream water sampled just downstream from the mined area increased from about 300 mg/L (milligrams per liter) to more than 1,500 mg/L, and the water changed from primarily a magnesium calcium bicarbonate to primarily a magnesium sulfate type. Monitored water levels in two wells completed in the perched aquifer(s) above the mine indicate that fractures from subsidence- related deformation drained the perched aquifer in the Blackhawk Formation. The deformation also could have contributed to the decrease in discharge of three springs above the mined area, but discharge from other springs in the area did not change ubstantially; thus, the relation between subsidence and spring discharge, if any, is not clear. No significant changes in the chemical character of water discharging from springs were detected, but the dissolved-solids concentration in water collected from a perched sandstone aquifer overlying the mined coal seams increased during mining activity.

Managing state energy conservation programs - The Minnesota experience  

NASA Astrophysics Data System (ADS)

The development and operation of energy conservation programs in the Minnesota Energy Agency (MEA) are discussed. The MEA has responsibility for voluntary conservation efforts, regulating energy efficient devices, and grant programs to audit and retrofit public buildings. The MEA has developed the plan under which the Minnesota utilities will provide conservation services to residential customers, including an on-site home energy audit. The relation between the Department of Energy (DOE) and state energy offices in implementing programs is considered. The DOE has provided technical assistance to the states through the development of a model audit. Steps are discussed to reduce the burdens imposed on the states by program planning, funding, and management responsibilities, including the consolidation of several existing state conservation programs. Improved policy analysis is suggested to correct inefficiencies in government programs.

Spring viremia of carp virus in Minnehaha Creek, Minnesota.  

PubMed

Spring viremia of carp virus (SVCV) causes a highly contagious and serious disease of freshwater cyprinid fishes, generating significant economic and ecological impacts throughout the world. The SVCV is therefore listed as a notifiable pathogen by the International Organization for Animal Health. In June 2011, a significant mortality event of wild common carp Cyprinus carpio occurred in Minnehaha Creek near its confluence with Mississippi River Pool 2 in Minneapolis, Minnesota. Clinical signs of moribund fish included hemorrhagic lesions in the skin, eyes, and internal adipose tissue. The SVCV was isolated from pooled kidney and spleen of the fish. Rhabdovirus particles were seen upon examination of infected cell culture fluid by electron microscopy. The virus was confirmed to be SVCV subtype Ia by reverse transcription PCR and sequencing. This is the first report of SVCV within the state of Minnesota and the ninth documented case in North America. PMID:23072656

MRX protects fork integrity at protein-DNA barriers, and its absence causes checkpoint activation dependent on chromatin context  

PubMed Central

To address how eukaryotic replication forks respond to fork stalling caused by strong non-covalent protein–DNA barriers, we engineered the controllable Fob-block system in Saccharomyces cerevisiae. This system allows us to strongly induce and control replication fork barriers (RFB) at their natural location within the rDNA. We discover a pivotal role for the MRX (Mre11, Rad50, Xrs2) complex for fork integrity at RFBs, which differs from its acknowledged function in double-strand break processing. Consequently, in the absence of the MRX complex, single-stranded DNA (ssDNA) accumulates at the rDNA. Based on this, we propose a model where the MRX complex specifically protects stalled forks at protein–DNA barriers, and its absence leads to processing resulting in ssDNA. To our surprise, this ssDNA does not trigger a checkpoint response. Intriguingly, however, placing RFBs ectopically on chromosome VI provokes a strong Rad53 checkpoint activation in the absence of Mre11. We demonstrate that proper checkpoint signalling within the rDNA is restored on deletion of SIR2. This suggests the surprising and novel concept that chromatin is an important player in checkpoint signalling. PMID:23376930

Calibration of quartz tuning fork spring constants for non-contact atomic force microscopy: direct mechanical measurements and simulations  

PubMed Central

Summary Quartz tuning forks are being increasingly employed as sensors in non-contact atomic force microscopy especially in the “qPlus” design. In this study a new and easily applicable setup has been used to determine the static spring constant at several positions along the prong of the tuning fork. The results show a significant deviation from values calculated with the beam formula. In order to understand this discrepancy the complete sensor set-up has been digitally rebuilt and analyzed by using finite element method simulations. These simulations provide a detailed view of the strain/stress distribution inside the tuning fork. The simulations show quantitative agreement with the beam formula if the beam origin is shifted to the position of zero stress onset inside the tuning fork base and torsional effects are also included. We further found significant discrepancies between experimental calibration values and predictions from the shifted beam formula, which are related to a large variance in tip misalignment during the tuning fork assembling process.

Experiments relating to the flow induced by a vibrating quartz tuning fork and similar structures in a classical fluid  

NASA Astrophysics Data System (ADS)

We report on an experimental study of the behavior of a number of commercially available quartz tuning forks oscillating in a classical cryogenic fluid, in the form of either liquid helium I or gaseous helium, extending our previous studies [M. Blazkova Phys. Rev. E 75, 025302 (2007)10.1103/PhysRevE.75.025302]. Measurements of the damping of the oscillations allowed us to deduce the drag on the prong of a fork, as a function of the velocity with which the prong moves, for various sizes of fork and various oscillation frequencies. Transitions to turbulent flow have been identified, and the dependence of the critical velocity, expressed as a dimensionless critical Keulegan-Carpenter number, on the dimensionless Stokes number has been established. These measurements have not allowed us to visualize the flow, so we have carried out visualization experiments with oscillating rods in water, the rod dimensions, and the frequencies of oscillation, being chosen so that the relevant dimensionless parameters are similar to those for the prongs of the forks. Some information about the nature of the instability that leads to turbulence has been obtained in this way, and the results for the critical Keulegan-Carpenter number for the rods in water have been compared with values for the tuning forks in a cryogenic fluid.

Simultaneous binding to the tracking strand, displaced strand and the duplex of a DNA fork enhances unwinding by Dda helicase.  

PubMed

Interactions between helicases and the tracking strand of a DNA substrate are well-characterized; however, the role of the displaced strand is a less understood characteristic of DNA unwinding. Dda helicase exhibited greater processivity when unwinding a DNA fork compared to a ss/ds DNA junction substrate. The lag phase in the unwinding progress curve was reduced for the forked DNA compared to the ss/ds junction. Fewer kinetic steps were required to unwind the fork compared to the ss/ds junction, suggesting that binding to the fork leads to disruption of the duplex. DNA footprinting confirmed that interaction of Dda with a fork leads to two base pairs being disrupted whereas no disruption of base pairing was observed with the ss/ds junction. Neutralization of the phosphodiester backbone resulted in a DNA-footprinting pattern similar to that observed with the ss/ds junction, consistent with disruption of the interaction between Dda and the displaced strand. Several basic residues in the 1A domain which were previously proposed to bind to the incoming duplex DNA were replaced with alanines, resulting in apparent loss of interaction with the duplex. Taken together, these results suggest that Dda interaction with the tracking strand, displaced strand and duplex coordinates DNA unwinding. PMID:25249618
