Far infrared all-sky survey

An all-sky survey at submillimeter waves is examined. Far-infrared all-sky surveys were performed using high-thoroughput bolometric detectors from a one-meter balloon telescope. Based on the large-bodied experience obtained with the original all-sky survey telescope, a number of radically different approaches were implemented. Continued balloon measurements of the spectrum of the cosmic microwave background were performed

The Grass River Soil Water Assessment Tool: A model for predicting sources and sinks of sediment

Soil Water Assessment Tool was implemented in the Grass River watershed, Michigan, to determine sources and sinks of sediments. The model was developed after watershed stakeholders such as the Tip of the Mitt watershed council and the Three Lakes Association, started receiving complaints from boaters who believed the Grass River was filling up with sediment at unprecedented rates. Small boat navigation was a concern. The model was developed from STATSGO soil data and 2006 era land cover extracted from Landsat Thematic Mapper imagery. Daily precipitation and temperature data from the Kalkaska climate station was used to force the model. Results from the uncalibrated model suggest that Finch Creek is the largest source of sediment in the Grass River, contributing some 401 tons/year over the period between Jan 1, 2006 and December 31, 2010. Cold Creek is the second largest source, contributing 166.8 tons/yr followed by Shanty Creek, contributing 50.0 tons/yr over the same period. Together the three tributaries contribute 363 cubic meters of sediment (equivalent to over 47 dump truck loads) every year to the Grass River. Several stream segments in Finch creek were found to be significant sinks of sediments. Sediments eroded mainly from areas underlain by the Emmet-Montcalm soil series. Urbanized areas in Shanty Creek appear to be significant sources of sediment, however much of this sediment is deposited before it reaches Grass River

Far Infrared All-Sky Survey

Precise measurements of the angular power spectrum of the Cosmic Microwave Background (CMB) anisotropy will revolutionize cosmology. These measurements will discriminate between competing cosmological models and, if the standard inflationary scenario is correct, will determine each of the fundamental cosmological parameters with high precision. The astrophysics community has recognized this potential: the orbital experiments MAP and PLANCK, have been approved to measure CMB anisotropy. Balloon-borne experiments can realize much of this potential before these missions are launched. Additionally, properly designed balloon-borne experiments can complement MAP in frequency and angular resolution and can give the first realistic test of the instrumentation proposed for the high frequency instrument on PLANCK. The MAXIMA experiment is part of the MAXIMA/BOOMERANG collaboration which is doing balloon observations of the angular power spectrum of the Cosmic Microwave Background from l = 10 to l = 800. These experiments are designed to use the benefits of both North American and Antarctic long-duration ballooning to full advantage. We have developed several new technologies that together allow the power spectrum to be measured with unprecedented combination of angular resolution, beam throw, sensitivity, sky coverage and control of systematic effects. These technologies are the basis for the high frequency instrument for the PLANCK mission. Our measurements will strongly discriminate between models of the origin and evolution of structure in the universe and, for many models, will determine the value of the basic cosmological parameters to high precision

Use of Ground Penetrating Radar to identify the presence and orientation of Graves in St. Brigitts Cemetery, Bergen New York

Ground Penetrating Radar (GPR) was employed to determine the location of all caskets buried at the St. Brigitts cemetery, located at the intersection of Munger Rd and Rte 33 in Bergen, New York. The study, which located 432 sites in the cemetery where caskets are buried, will assist the Diocese of St. Brigitts Church in their plans to improve the cemetery. These improvements include the refurbishment of existing headstones, the replacement of headstones where none currently exist, and the identification of land areas where new graves may be located

Frederick Farm Well Contamination: Borehole Camera Analysis of Bedrock Structure

A borehole camera analysis was conducted at the Frederick Farm to characterize bedrock structure, quantify fractures, and establish the condition of the well casing. Through the use of a GeoVISION Jr.™ and recording equipment, footage of the camera decent was recorded for data analysis. The 5 ft well casing appeared intact and was properly constructed within bedrock. The well above the water table contained few fractures and appeared to be weathered. Flowing water was visible in the two main fractures, located on the south (5.5 ft depth) and south-western (13.5 ft depth) walls of the well respectively. The water table interface was observed at 31.125 ft depth. Below the water table the well was laden with many fractures. The size of the fractures appear to increase in size with depth, with the larger fractures approaching ~1 ft in thickness. Also noted in this interval were areas of enhanced chemical weathering, particularly below 62.5 ft. The bedrock fracture profile is indicative of a well built within heavily fractured karstic limestone

The impact of the COVID-19 pandemic on cancer care.

The COVID-19 pandemic has disrupted the spectrum of cancer care, including delaying diagnoses and treatment and halting clinical trials. In response, healthcare systems are rapidly reorganizing cancer services to ensure that patients continue to receive essential care while minimizing exposure to SARS-CoV-2 infection

Interrater Reliability of Extrapyramidal Signs in a Group Assessed for Dementia

Extrapyramidal signs were rated by three neurologists in 20 patients who had either been diagnosed as having probable Alzheimer's disease or who were being evaluated for dementia. In general, good inter-rater reliability was found for the presence or absence of extrapyramidal signs, although agreement over the presence of some signs was reduced when distinctions between normality and slight departures from normality were required
