Fiscal Year 2011 FHWA-536 Report for the Kentucky Transportation Cabinet
The Federal Highway Administration (FHWA) requires state transportation agencies to submit a biennial report on local highway finances. The purpose of these reports is to provide FHWA with the data it needs to capture the financing of highway activities at the local level. Based on this information, it can identify trends in revenue, expenditures, investments, and program development, and in turn make decisions about future investments. The report, FHWA-536, asks agencies to report on four areas of local highway finance: 1) disposition of highway-user revenues; 2) revenues used for roads and streets identified by source and funding type; 3) road and street expenditures identified by purpose of activity; and 4) local highway debt status. This document summarizes data submitted to fulfill the Kentucky Transportation Cabinet’s FHWA-536 obligations in FY 2011. Total receipts were 110,761,911 compared to FY 2009. Total disbursements equaled 157,135,174 over FY 2009

H+ transport is an integral function of the mitochondrial ADP/ATP carrier.
The mitochondrial ADP/ATP carrier (AAC) is a major transport protein of the inner mitochondrial membrane. It exchanges mitochondrial ATP for cytosolic ADP and controls cellular production of ATP. In addition, it has been proposed that AAC mediates mitochondrial uncoupling, but it has proven difficult to demonstrate this function or to elucidate its mechanisms. Here we record AAC currents directly from inner mitochondrial membranes from various mouse tissues and identify two distinct transport modes: ADP/ATP exchange and H+ transport. The AAC-mediated H+ current requires free fatty acids and resembles the H+ leak via the thermogenic uncoupling protein 1 found in brown fat. The ADP/ATP exchange via AAC negatively regulates the H+ leak, but does not completely inhibit it. This suggests that the H+ leak and mitochondrial uncoupling could be dynamically controlled by cellular ATP demand and the rate of ADP/ATP exchange. By mediating two distinct transport modes, ADP/ATP exchange and H+ leak, AAC connects coupled (ATP production) and uncoupled (thermogenesis) energy conversion in mitochondria
Hubble Space Telescope imaging of the WR 38/WR 38a cluster
We are conducting a high angular resolution imaging survey of Galactic Wolf-Rayet stars using the Wide Field Planetary Camera 2 aboard the Hubble Space Telescope (HST). We have found a small stellar cluster associated with the faint, close pair WR 38 and WR 38a. We present astrometric measurements and photometry in the wideband F336W (U), F439W (5), and F555W (V) filter system for the cluster and nearby stars. We combine our photometry with Johnson and IR magnitudes and compare the observations with calibrated model results for reddened stars to adjust the HST zero points and to identify five probable main-sequence members of the cluster. A least-squares fit of the colors and magnitudes of this set yields a cluster reddening of E(B - V) = 1.63 ±0.05 mag and a distance of 10 -4 +12 kpc for an assumed ratio of total to selective extinction of R = 3.1. We discuss the relationship of this cluster to other objects along the line of sight. If situated at a distance of ≈8 kpc, then the cluster would reside in a dense region of the Carina spiral arm, close to a giant molecular cloud and the starburst cluster NGC 3603.Facultad de Ciencias Astronómicas y Geofísica
An eddy-stimulated hotspot for fixed nitrogen-loss from the Peru oxygen minimum zone
Fixed nitrogen (N) loss to biogenic N2 in intense oceanic O2 minimum zones (OMZ) accounts for a large fraction of the global N sink and is an essential control on the ocean's N budget. However, major uncertainties exist regarding microbial pathways as well as net impact on the magnitude of N-loss and the ocean's overall N budget. Here we report the discovery of a N-loss hotspot in the Peru OMZ associated with a coastally trapped mesoscale eddy that is marked by an extreme N deficit matched by biogenic N2 production, high NO2− levels, and the highest isotope enrichments observed so far in OMZ's for the residual NO3−. High sea surface chlorophyll (SSC) in seaward flowing streamers provides evidence for offshore eddy transport of highly productive, inshore water. Resulting pulses in the downward flux of particles likely stimulated heterotrophic dissimilatory NO3− reduction and subsequent production of biogenic N2. The associated temporal/spatial heterogeneity of N-loss, mediated by a local succession of microbial processes, may explain inconsistencies observed among prior studies. Similar transient enhancements of N-loss likely occur within all other major OMZ's exerting a major influence on global ocean N and N isotope budgets
Hubble Space Telescope Imaging of the WR 38/WR38a Cluster
We are conducting a high angular resolution imaging survey of Galactic
Wolf-Rayet stars using the Wide Field and Planetary Camera 2 aboard the Hubble
Space Telescope. We have found a small stellar cluster associated with the
faint, close pair WR 38 and WR 38a. We present astrometric measurements and
photometry in the wide-band F336W (U), F439W (B), and F555W (V) filter system
for these cluster and nearby stars. We compare their colors and magnitudes with
calibrated model results for reddened stars to identify seven probable main
sequence members of the cluster. A least-squares fit of the colors and
magnitudes of this set yields a cluster reddening of E(B-V) = 1.45 +/- 0.14 mag
and a distance of 3.7^{+3.8}_{-1.2} kpc. We discuss the relationship of this
cluster to other objects along the line of sight, and we argue that the
distance probably lies in the range 5 - 8 kpc (but is not as great as 14.5 kpc
distance recently advocated by Shorlin, Turner, & Pedreros). At a distance of 8
kpc, the cluster would reside in a dense region of the Carina spiral arm, close
to a giant molecular cloud and the starburst cluster NGC 3603.Comment: Submitted to AJ, 24 pages, 3 figures Content is significantly change
