Vision With the Black Shawl

YOU KNOW, I never used to take much stock in these stories about visions. Not that I denied them, you understand, but it was always somebody else who was having the visions. But all that was before I met a certain lady about a year ago..

Low Template DNA: Tad, Touch and Traces

Small amounts of DNA, typically less than 100 pg, termed Low Template (LT) DNA which is extremely useful in forensic casework. The current advancement of highly sensitive multiplex PCR systems consisting of short tandem repeat (STR) markers have allowed the development of genetic profiles from much lower quantities of DNA, from such samples. However, this sensitivity of the STR profiling systems also leads to issues of secondary transfer of LT DNA such as the implication of innocent parties as a result of background contamination and profiles having artefacts due to stochastic effects. This review explores the varying deposition mechanisms, technological advancements in both collection and analysis, and ultimately evaluates the usefulness of LT DNA considering its admissibility as forensic evidence

Field Evaluation of Non-Contact Flow Measurement Device - PID

The Irrigation Training and Research Center (ITRC) has analyzed the data from several non-contact volumetric flow meter models under various conditions. This testing was done with support from technical services contracts with the California Department of Water Resources (DWR) and the United States Bureau of Reclamation (USBR)

Field Evaluation of Non-Contact Flow Measurement Device - BCID

The Irrigation Training and Research Center (ITRC) is currently testing several non-contact volumetric flow meter models under their technical services contracts with the California Department of Water Resources (DWR) and the United States Bureau of Reclamation (USBR). In April 2020, a Sommer RQ-30A non-contact flow meter was installed at Banta Carbona Irrigation Districts (BCID) Main Canal approximately 180 ft downstream of the discharge from Pumping Plant 1. The meter was mounted at midspan along a footbridge that crosses the throat of an ITRC designed subcritical contraction structure (see Figure 1). An existing SonTek Acoustic Doppler Flow Meter (ADFM) was installed on the invert of the structure and positioned directly beneath the non-contact meter installation. After the initial installation, current metering was performed to gauge the “out-of-the-box” accuracy of the RQ-30A sensor. Over the course of the study, ITRC periodically performed current metering using a SonTek RiverSurveyor M9 to evaluate the accuracy of SonTek ADFM. The SonTek ADFM was used as the standard device for comparing the non-contact meter measurements
