Increasing edge sensitivity in a radiation detector
An apparatus and method to increase the sensitivity at the edge of radiation detector blocks is disclosed herein. Reduced sensitivity can result from photons entering a first detector block, escaping, and scattering into an adjacent detector, thereby depositing energy into two detectors blocks. Energy lost into adjacent detector blocks can be compensated with energy detected in the adjacent detector block. This can be done, for example, by processing channels from multiple detector blocks with one Field Programmable Gated Array (FPGA) on one Event Process Module (EPM) board. This can enable summing energy of one detector block with energy from an adjacent detector block when the initial interaction occurs at the edge of the first detector block. This can result in a better estimate of the amount of energy associated with the initial photon being detected. |

Neurotensin as a marker and therapeutic target for sepsis
Sepsis is a complex, incompletely understood and often fatal disorder, typically accompanied by hypotension, that is considered to represent a dysregulated host response to an infection. Neurotensin (NT) is 13-amino-acid peptide that, among its multiple effects, induces hypotension. It is shown herein that plasma concentrations of NT are increased in humans with sepsis and in mice after caecal ligation and puncture (CLP), a model of sepsis. Mast cells can degrade NT through neurotensin receptor 1-and neurolysin-dependent mechanisms, diminishing the hypotensive effects of NT, reducing intraperitoneal NT concentrations, and improving survival. These findings show that mast cells can regulate NT concentrations, and identify NT as a biomarker and therapeutic target in sepsis. |

Density adjustment by the use of light cycle oil, (LCO), for recovery and reclamation of spilled oil following the 2010 off-shore leak in the gulf
Our idea is a new procedure that can be used to clean up and recover oil from spills or oil leaking from damaged ships or rigs. The reclamation is accomplished by restoring the oil's light density. This is accomplished with density control by adding light cycle oil, (LCO), with a density of 0.82 g/ml, to the oil being recovered for the purpose of reprocessing in refineries. Recovery is made possible through the application of solubility rules found in organic chemistry. LCO is a mixture of many different molecular weight hydrocarbons that have many different numbers of carbons in their chains, branches, or rings. Each of these hydrocarbons dissolves a small part of the oil preparing the mixture for collection and reprocessing as refinery feedstock. Furthermore, this idea can prevent the need for landfill storage and offset the cost of recovery. |

An oil skimmer includes a frame for attaching a porous collection bag. The frame automatically tilts in response to water flow, relative to the frame, and the frame automatically returns to its original (“neutral”) position when the water flow ceases.

However, in the neutral position, the frame orients the mouth of the bag upward and such that the mouth is above the surface of the water to prevent previously captured contaminants from escaping from the bag and floating away. Optionally, the frame may be releasably locked in the neutral position to facilitate bag replacement or when no collection is desired. The skimmer may be mounted between hulls of a catamaran. |

Method of determining flood points of packed columns
A flood point for a packed column is determined by providing a data set of gas pressure drop values as a function of gas flow rate values at several liquid flow rates through a packed column, known flood point value for one liquid flow rate, setting flood point values for higher liquid flow rates at values lower than the known flood point value, and setting flood point values for lower liquid flow rates at values higher than the known flood point value, followed by expressing gas flow rates for liquid flow rates as fractions of the flood point value for each respective liquid flow rate. At a constant gas pressure drop, the method then includes calculating an average fractional flood point value for the liquid flow rates and minimizing the standard deviation between the fractional flood point value at different liquid flow rates and the calculated average fractional flood point value by iteratively resetting fractional flood point values and recalculating the average fractional flood point value for the liquid flow rates, thus resulting in determining a flood point for the packed column at any liquid flow rate, and thereby producing a plot of pressure drop as a function of fraction of flood point at any liquid flow rate, or a mathematical expression thereof that can be used in a computer-implemented column design and process modeling. |
