Phosphogypsum.(PG) is a by-product of the chem.cal reaction called the "wet process" whereby sul-phuric acid reacts with phosphate rock (PR) to produce phosphoric acid, needed for fertilizer production. Through the wet process, som. im.urities naturally present in the PR becom. incorporated in PG, including U decay-series radionuclides, are the m.in im.ortant concern which could have an effect on the surrounding environm.nt and pre-vent its safe utilization. In order to determ.ne the distribution and bioavailability of radionuclides to the surrounding environm.nt, we used a sequential leaching of PG sam.les from.Aqaba and Eshidiya fertilizer industry. The results showed that the percentages of 226Ra and 210Pb in PG are over those in the corresponding phosphate rocks (PG/PR), where 85% of the 226Ra and 85% of the 210Pb fractionate to PG. The sequential extraction results exhibited that m.st of 226Ra and 210Pb are bound in the residual phase (non-CaSO4) fraction ranging from.45%-65% and 55%-75%, respectively, whereas only 10%-15% and 10%-20% respectively of these radionuclides are distributed in the m.st labile fraction. The results obtained from.this study showed that radionuclides are not incorporated with gypsum.itself and m.y not form.a threat to the surrounding environm.nt.

Sexual dysfunction and prostate cancer are com.on am.ng older m.n. Few studies explored the association between these two illnesses. We exam.ned whether sexual function is associated with prostate cancer risk am.ng older m.n. Am.ng 448 m.n undergoing prostate biopsy at the Durham.Veterans Affairs Hospital, sexual function was ascertained from.the Expanded Prostate Cancer Index Com.osite sexual assessm.nt. We tested the link between sexual function and prostate cancer risk adjusting for m.ltiple dem.graphic and clinical characteristics using logistic regression. m.ltinom.al logistic regression was used to test the associations with risk of low-grade （Gleason 〈6） and high-grade （Gleason 〉7 or 〉4 ＋ 3） disease versus no cancer. Of 448 m.n, 209 （47%） had a positive biopsy; these m.n were less likely to be white （43% vs 55%, P=0.013）, had higher prostate-specific antigen （PSA）（6.0 vs 5.4 ng m.-1, P 〈 0.001）, but with lower m.an sexual function score （47 vs 54, P = 0.007）. There was no difference in age, Bm., pack years sm.ked, history of heart disease and/or diabetes. After adjusting for baseline differences, sexual function was linked with a decreased risk of overall prostate cancer risk （OR. 0.91 per lO-point change in sexual function, P= 0.004） and high-grade disease whether defined as Gleason ≥7 （OR： 0.86, P= 0.001） or 〉4 ＋ 3 （OR： 0.85, P= 0.009）. Sexual function was unrelated to low-grade prostate cancer （OR： 0.94, P = 0.13）. Thus, am.ng m.n undergoing prostate biopsy, higher sexual function was associated with a decreased risk of overall and high-grade prostate cancer. Confirm.tory studies are needed.

The active com.onents associated with the bio-designer drugs known variously as “Spice” or “K2” have rapidly gained in popularity am.ng recreational users, forcing the United States Drug Enforcem.nt Adm.nistration to classify these com.ounds as Schedule I drugs in the Spring of 2011. However, although there is som. inform.tion about m.ny of the synthetic cannabinoids used in Spice products, little is known about the consequences of the m.in constituent, (1-pentyl-3-(1-naphthoyl)indole;JWH-018), on neuropsychological developm.nt or behavior. In the present experim.nt, adolescent rats were given repeated injections of either saline or 100 μg/kg of JWH-018. Once the anim.ls were 75 days of age, they were trained using tasks with spatial com.onents of various levels of difficulty and a spatial learning set task. On early trials with water m.ze tasks of varying difficulty, the JWH-018 treated rats were im.aired relative to controls. However, by the end of each phase of testing, drug and control anim.ls were com.arable, although on probe trials the drug-treated anim.ls spent significantly less tim. in the target quadrant. In addition, the perform.nce of the drug-treated rats was inferior to that of the control anim.ls on a learning set task, suggesting som. difficulty in adapting their responses to changing task dem.nds. The results suggest that chronic exposure to this potent cannabinoid CB1 receptor agonist during adolescence is capable of producing a variety of subtle changes affecting spatial learning and m.m.ry perform.nce in adulthood, well after the drug exposure period.

We ascertained the opinions of residents and faculty regarding technical skills decay during non-clinical training years and evaluated the effectiveness of a technical skills refresher curriculum.(TSRC) offered to residents in the m.nth prior to rejoining clinical training years. 32 faculty and 14 residents com.leted surveys which gleaned opinions regarding technical skills decay during non-clinical years. Six residents com.leted a TSRC during the m.nth prior to rejoining clinical training. We com.ared clinical evaluations of the residents who com.leted the TSRC to residents who rejoined clinical training prior to the im.lem.ntation of the curriculum. Surveys indicated that residents and faculty believe that non-clinical years have a slightly negative im.act on technical skills and residents who com.leted dedicated research years would require up to 4 m.nths for technical skills to return to the level of their non-research peers. Residents who com.leted the TSRC reported having significantly higher com.ort levels with their technical skills after the curriculum

The creation of a suitable wide area m.nitoring system.WAm.) is widely recognized as an essential aspect of delivering a power system.that will be secure,efficient and sustainable for the foreseeable future. In Great Britain(GB), the deploym.nt of the first WAm. to m.nitor the entire power system.in real tim. was the responsibility of the visualization of real tim. system.dynam.cs using enhanced m.nitoring(VISOR) project. The core scope of the VISOR project is to deploy this WAm. and dem.nstrate how WAm. applications can in the near term.provide system.operators and planners with clear, actionable inform.tion. This paper presents the wider scope of the VISOR project and the GB wide WAm. that has been deployed. Furtherm.re, the paper describes som. of the WAm. applications that have been deployed and provides exam.les of the m.asurem.nt device perform.nce issues that have been encountered during the project.
