Penile plethysmography is amongst the best measures for prediction of sexual recidivism and has been extensively researched. However, there are a variety of criticisms regarding use of penile plethysmography (PPG), including financial investment, significant training needs, lack of standardization, intrusive nature of the measure, extensive time for testing, and inability to use PPG with all groups of sexual offenders (e.g., women and adolescents).

Abstract:
Abstract This research work presents a study of the combined influence of the partial pressure of H2S and the concentration of free acetic acid on the general and localized CO2 corrosion at the bottom of the line. Experiments were carried out during 21 days in three 4” internal diameter flow loops at 70°C with 2 bars of CO2. The flow regime was stratified for all of the experiments. It was found that trace amounts of H2S (from 0.004 to 0.13 bars) greatly retards the CO2 corrosion with general corrosion rates usually 10 to 100 times lower than their pure CO2 equivalent. However, the most protec

Abstract The environmentally-assisted cracking (EAC) of three wrought corrosion-resistant alloys (CRAs) with a minimum yield strength of 110ksi (760MPa) was investigated between 70°F (21°C) and 450°F (232°C) through weekly thermal cycles totalizing 42 days. The thermal cycling was introduced to approximate service equipment conditions and gain additional confidence on the EAC-free limits of all three CRAs. Alloys 17-4PH, K-500, and 925 were selected and exposed to a 180,000-ppm NaCl brine (pH=2.75) in equilibrium with 1000 psi (68.95 bar) H2S, 1000 psi (68.95 bar) CO2, and 2500 psi (172.37 bar

Abstract A parametric test program involving completion alloys in supercritical CO2 was conducted using both isothermal and non-isothermal cycles in the presence of contaminants (i.e., H2O, NO2, SO2, H2S, H2) above typical impurity limits for carbon capture and sequestration (CCS). The isothermal testing consisted of 4500 psi (310 bar) autoclave tests at 175°F (79°C) with the test materials in supercritical CO2, and optionally, in a NaCl-rich brine in equilibrium; the non-isothermal testing was similar, but included three consecutive cycles with 250°F (121°C) and 70°F (21°C) exposures.

This study focused on understanding the impact of transverse cracks on the residual capacity and load rating analysis of in-service precast prestressed concrete (PPC) deck beams. Two decommissioned (33 × 36 and 21 × 36) PPC deck beams were tested under four-point bending loads to assess the impact of transverse cracks on the structural performance of the beams. Finite element and theoretical cracked section analyses were also performed to investigate the capacity of the as-built and cracked PPC deck beam. Transverse cracks reduced the load rating capacity of the 33 × 36 beam by almost 34%, whi

The overall goal of this proposal is to identify critical host and pathogen factors that modulate P. expansummycotoxin genes and pathways which are required for PAT production and virulence.
