• Measurement of CSP and PV soiling using real-time sensors (DustIQ TraCS). Well-described methodology for processing raw data from DustIQ TraCS sensors. Simultaneous long-term comparative analysis the effect on collectors. The mirrors with an annually averaged rate -1.18 %/day is around 5 to 6 times higher compared (-0.23 %/day). drop in optical efficiency solar collectors due extreme events (...

Soiling can greatly reduce both the efficiency of photovoltaic (PV) installations and signals radiometers. The knowledge current soiling losses a PV installation be used to optimize cleaning schedule avoid false alarms related other issues that might cause underperformance. Underperformance detected by comparing measured modeled production derived using pyranometer or reference cell measurement...

Ensuring good game meat hygiene is a challenge in the hunting supply chain. Game carcasses can be soiled with intestinal contents or other substances from environment due to and handling practices. This soiling increase microbial load (ML) of carcass resulting meat. The aim this study was investigate whether rinsing unsoiled body cavities drinking water reduce ML carcasses. Carcasses 23 roe dee...

In order to evaluate environmental controls on the soiling formation and decay of building stones a set of mapping and physical and chemical analyses were carried out on granite from a historical church in the polluted centre of Rio de Janeiro. These techniques highlight the increasing of threatening damage on generally perceived as a durable building material, caused by granular disaggregation...

PURPOSE This study aimed to test the effectiveness of home transcutaneous electrical stimulation (TES) when patients with slow-transit constipation (STC) were trained by a naive clinician. METHODS A surgeon was trained to teach the TES method to STC children who then self-administered at home (1 hour a day, 3-6 months) using a battery-powered interferential stimulator. Bowel diaries, PedsQL4....

Purpose. To evaluate ileorectal anastomosis (IRA) in selected ulcerative colitis patients. Methods. Early and late complications after IRA and IPAA were investigated. Bowel function and quality of life were assessed. Functional and QoL studies were performed as a matched pair analysis, comparing 98 patients who underwent IRA versus 98 patients who underwent IPAA. Results. In IRA group, 2 patien...

In general, dirty banknotes that have creases or soiled surfaces should be replaced by new banknotes, whereas clean banknotes should be recirculated. Therefore, the accurate classification of banknote fitness when sorting paper currency is an important and challenging task. Most previous research has focused on sensors that used visible, infrared, and ultraviolet light. Furthermore, there was l...
