Project Chariot - Phase III: Progress Report

This is a preliminary report and is NOT FOR PUBLICATIONBotanical investigations of the Cape Thompson - Ogotoruk Creek region of northwest Alaska were initiated in May, 1959 by the University of Alaska under contract with the United States Atomic Energy Commission (Contract No. AT (04 -3 ) - 310). The first summer's field work was largely exploratory and descriptive in nature and included a species inventory of the vascular plants, mosses, and lichens; a qualitative description of the main vegetation types in Ogotoruk Valley; and a preliminary mapping of the vegetation types within the valley. The results of the first summer's field work and winter visits have been partially reported in two reports: Ogotoruk Valley Botanical Project, December, 1959 Report, and the Phase II Interim Pinal Report, Ogotoruk Valley Botanical Project, June, 1960. For brevity, these will be referred to as the December, 1959 Botanical Report, and the June, 1960 Botanical Report. Materials reported in these earlier reports will not be repeated in this December, 1960 report. Botanical investigations were continued during the summer and fall of 1960. The objectives of the 1960 field season were as follows: 1. To measure the frequency, cover, and synthetic features of the main vegetation types in Ogotoruk Valley. 2. To establish control vegetation plots in areas outside the potential blast and fallout area and to extend our understanding of the vegetation of the northwestern Alaska Coast. 3. To complete records of species occurrence in the area by continuing plant collections and identifications. 4. To revise and complete the vegetation map of the area. 5. To continue seed germination studies on certain species. 6. To commence palynological studies of bog and lacustrine sediments. 7. To initiate studies on some of the ecological problems in the Ogotoruk Valley area. a. to understand the relationship between permafrost, annual freezing-thawing cycles, and plant distribution. b. to understand the inter-relationships of the activities of the arctic ground squirrel and vegetation in the valley. Preliminary results of the 1960 field work and additional information from the 1959 season are included in this report

Electronic Construction Collaboration System – Phase III, December 2011

This phase of the electronic collaboration project involved two major efforts: 1) implementation of AEC Sync (formerly known as Attolist), a web-based project management system (WPMS), on the Broadway Viaduct Bridge Project and the Iowa Falls Arch Bridge Project and 2) development of a web-based project management system for bridge and highway construction projects with less than $10 million in contract value. During the previous phase of this project (fiscal year 2010), the research team helped with the implementation process for AEC Sync and collected feedback from the Broadway Viaduct project team members before the start of the project. During the 2011 fiscal year, the research team collected the post-project surveys from the Broadway Viaduct project members and compared them to the pre-project survey results. The results of the AEC Sync implementation on the Broadway project were positive. The project members were satisfied with the performance of the AEC Sync software and how it facilitated document management and its transparency. In addition, the research team distributed, collected, and analyzed the pre-project surveys for the Iowa Falls Arch Bridge Project. The implementation of AEC Sync for the Iowa Falls Arch Bridge Project appears to also be positive, based on the pre-project surveys. The fourth phase of this electronic collaboration project involves the identification and implementation of a WPMS solution for smaller bridge and highway projects. The workflow for the shop drawing approval process for sign truss projects was documented and used to identify possible WPMS solutions. After testing and evaluating several WPMS solutions, Microsoft SharePoint Foundation’s site pages were selected to be pilot-tested on sign truss projects. Due to the limitation on the SharePoint license that the Iowa Department of Transportation (DOT) has, a file transfer protocol (FTP) site will be developed alongside this site to allow contractors to upload shop drawings to the Iowa DOT. The SharePoint site pages are expected to be ready for implementation during the 2012 calendar year

Public Perceptions of the Midwest’s Pavements - Iowa - Phase III

There are several objectives to this report. The first objective is to describe the sample with regard to the physical pavement data and three measures of driver satisfaction. In this section, the proportion of respondents who are satisfied with pavements on two-lane, rural, state highways will be examined and the distribution of pavement condition and roughness indices will be presented. The second objective will be a short description of the highway segments and any differences in satisfaction found between regions and pavement types. This was done in Phase II in each state and a letter sent showing the results in all three states. That letter sets forth the revised work plan and budget for Phase III of the project. The third objective is to describe the relationship between physical pavement characteristics and driver satisfaction. This will include a description of both the magnitude of relationship as well as identifying critical International Road Index (IRI) and Pavement Condition Index (PCI) cutoffs where a majority of the sample were satisfied. This will be done for comparative purposes with the Phase II approach, using the total sample to compute cumulative percentages responding to each of the three series of satisfaction questions

Aging in vitro and D-glucose uptake kinetics of diploid human fibroblasts

By use of a rapid technique, initial rates of D-glucose transport were obtained during the lifespan in vitro of a commercially available strain of human embryo lung fibroblasts (Flow 2000). The apparent Km of the D-glucose carrier did not change during senescence in vitro: = 1.8 mM (range 1.3-2.3) in phase II, = 1.8 mM (range 1.5-2.2) in phase III. Transport rates remained constant in stationary phase II cultures, which had completed between 30% and 80% of their replicative lifespan. A wide variation, however, was observed in terminally differentiated cells (phase III), which showed a two- to threefold increase in average cell size and protein content. In some senescent cultures, glucose transport calculated on a per cell basis was also two-to threefold increased, while it was strongly decreased (-75%) in others. When calculated per unit of cell water, protein, and surface area, respectively, transport rates in phase III cultures ranged from values established for stationary phase II cultures down to very low values. Detaching cells flushed off from senescent cultures did not show measurable rates of glucose transport into the inulin impermeable cell space. Present evidence argues against the idea that an impairment of D-glucose transport might precede loss of replicative potential in aging human fibroblasts. Instead our data indicate that the transport capacity of cell membrane finally decreases during postreplicative senescence in terminally differentiated cells

Project 8 Phase III Design Concept

We present a working concept for Phase III of the Project 8 experiment, aiming to achieve a neutrino mass sensitivity of $2~\mathrm{eV}$ ($90~\%$ C.L.) using a large volume of molecular tritium and a phased antenna array. The detection system is discussed in detail.Comment: 3 pages, 3 figures, Proceedings of Neutrino 2016, XXVII International Conference on Neutrino Physics and Astrophysics, 4-9 July 2016, London, U
