Practical experience of using ultrasound flowmeters at the measurement associated petroleum gas
© Published under licence by IOP Publishing Ltd. The results of field tests of several ultrasound flowmeters at existing oil and gas extraction objects are given in the paper. Measured medium - associated petroleum gas. This work aims to create a unified system for measuring the amount and parameters of APG in order to reduce operating costs
Assessing Health Needs of the Burlington Probation and Parole Population
The Burlington Probation and Parole population confronts numerous social, economic, and healthcare challenges upon their return to the community. While health and healthcare issues of inmates have been studied extensively, the health status and medical issues of the reentry offenders, particularly in rural areas have not been previously assessed. Data about health risks, major medical issues, and lifestyle choices among offenders on parole in the rural setting may prove helpful in the identification of preventative measures and development of strategies to promote positive health behaviors among the target population. The aim of this study is to evaluate the health risks among offenders on parole in the Burlington area and guide recommendations towards improving their health outcomes through community and educational initiatives. We also sought to gain a better understanding of the barriers within the rural setting that prevent positive health behaviors among the parolees upon their reintegration into the communityhttps://scholarworks.uvm.edu/comphp_gallery/1068/thumbnail.jp

Suppression of electron spin relaxation in Mn-doped GaAs
We report a surprisingly long spin relaxation time of electrons in Mn-doped
p-GaAs. The spin relaxation time scales with the optical pumping and increases
from 12 ns in the dark to 160 ns upon saturation. This behavior is associated
with the difference in spin relaxation rates of electrons precessing in the
fluctuating fields of ionized or neutral Mn acceptors, respectively. For the
latter the antiferromagnetic exchange interaction between a Mn ion and a bound
hole results in a partial compensation of these fluctuating fields, leading to
the enhanced spin memory.Comment: 4 pages, 4 figure
Anisotropic Magnetoconductance in Quench-Condensed Ultrathin Beryllium Films
Near the superconductor-insulator (S-I) transition, quench-condensed
ultrathin Be films show a large magnetoconductance which is highly anisotropic
in the direction of the applied field. Film conductance can drop as much as
seven orders of magnitude in a weak perpendicular field (< 1 T), but is
insensitive to a parallel field in the same field range. We believe that this
negative magnetoconductance is due to the field de-phasing of the
superconducting pair wavefunction. This idea enables us to extract the finite
superconducting phase coherence length in nearly superconducting films. Our
data indicate that this local phase coherence persists even in highly
insulating films in the vicinity of the S-I transition.Comment: 4 pages, 4 figure RevTex, Typos Correcte
A proposed reaction channel for the synthesis of the superheavy nucleus Z = 109
We apply a statistical-evaporation model (HIVAP) to calculate the cross
sections of superheavy elements, mainly about actinide targets and compare with
some available experimental data. A reaction channel Si + Am is
proposed for the synthesis of the element Z = 109 and the cross section is
estimated.Comment: 4 pages, 2 figures, 2 tables; two typos are corrected in Ref. [12]
