Objective: We evaluated the effectiveness of a Cable Safety Barrier (CSB) system in preventing Run-Off-Road (ROR) Vehicle Immersions (VIs) and fatalities in canals along the I-75 freeway (Alligator Alley) in Collier County, Florida. The CSB system, which runs along both sides of the 80-km stretch of freeway and was installed between 2003 and 2004. Methods: Data from the Fatal Analysis Reporting System (FARS) were used to compare annual VIs and VI fatalities between pre-installation of the CSB system (1995-2002) to post-installation (2005-2012). As well, post-installation data from the Florida Department of Transport (FDOT) (2007-2011) and police reports were reviewed to determine the number of, and manner in which, vehicles were either contained by, or crossed, the CSB by either penetrating or overriding the barriers. Results: Pre- to post-installation, total accidents increased from 81.4/y to 106.2/y, accidents resulting in VIs decreased from 13.8% to 2.4%, and accidents resulting in VI fatalities decreased from 3.4% to 0.4% (FDOT). Fatal vehicle immersions decreased from 2.4/y to 0.9/y (P<0.01) and vehicle immersion fatalities decreased from 3.3/y to 1.4/y (P<0.05) (FARS). Post-installation, 531 accidents occurred with 110 ROR vehicles travelling towards the canals; 91 vehicles contacted the CSB with only 14 vehicles (15.4%) penetrating the barrier, and 7 (7.7%) overriding the barrier (FDOT). Conclusion: The CSB system along I-75 in Collier County dramatically decreased ROR vehicles from reaching the parallel canals, and consequent vehicle immersion fatalities. Results support the installation of lateral CSB systems on other high-risk roadways to reduce ROR crashes into water, or with other secondary hazards.

The upper catchment of Ikopa has great potential for surface or sub-surface water resources. The Ikopa River plays an important role in the water supply of the plain of Antananarivo. Knowing that surface water is abundant but exposed to the high risk of pollution, and groundwater remains less exploited because of the insufficiency of the study concerning the recharge and the sources of their mineralization. The objective of this research is to use the isotope method to characterize groundwater to determine their origin and recharge process. The results of chemical analysis show three different facies type of groundwater which dominated by the sodium, nitrate and chloride ions. The isotopic compositions of the waters sampled vary respectively from -7.25‰ to 5-.09‰ for δ18O and from -46.9‰ to -24.7‰ for  δ2H. water form the lakes are more enriched compared to those rivers and groundwater. The diagram δ18O- δ2H shows that groundwater is recharged from local rainwater but undergoes low evaporation before infiltration. However, the results obtained from the parameters measured in situ show that a lateral recharge of groundwater from the streams feeds the neighboring aquifers. Lakes are fed by run-off during the rainy season.

ABSTRACTDisaster has been a part of our life. It comes unexpectedly, whenever and wherever that is. Because of the uncertainty, we have to care and Parepare ourselves to face it. Indonesia as an archipelago has a high risk of disaster, especially flood, particularly in Jakarta. It happened regularly every year. It also happens in other cities in Indonesia.Water scarcity in dry season and flood in rainy season become center of attention and influence us in many aspects of life. This study focus on on Prevention and Earl warning system. Online realtime information system is developer to get the data to be analized. The method is to capture the amount of rainwater volume in a watershed (Watershed), to calculate the amount of water as a contributor to flood / overflow of river water.The solution is to use the absorption well as one of the ways to prevent flood disaster, to get the optimal value as a flooding solution, the formula of hydrological formula and rainfall analysis data have been captured by realtime and online-based monitoring tools.In order to get accurat result, fuzzy method is used on matlabstools.Key words: floods, weather station ,zero run off, DASABSTRAKBencana sudah menjadi bagian dari kehidupan manusia yang datang tanpa diduga, dimana dan kapan saja terjadinya. Karena ketidak pastian tersebut , kita harus peduli dan menyiapkan diri untuk menghadapi bencana. Indonesia sebagai negara kepulauan yang rawan bencana terutama bencana banjir, dan ini menjadi seperti rutinitas setiap tahun terjadinya musibah banjir. Selain di Jakarta di daerah lain Indonesiapun terjadi bencana seperti ini bahkan seluruh dunia mengalami masalah bencana banjir ini, bahkan sampai memakan korban.Kelangkaan air pada musim kemarau dan Banjir pada musim Hujan menjadi fokus perhatian dari sebagian masyarakat dan tanpa terasa berimbas pada hampir seluruh lapisan masyarakat. Sehingga peneliti juga sangat menekankan pada kedua bencana ini, dimana pada umumnya semua pihak berfokus pada peringatan dini bencana; terutama berfokus pada penanganan bencana banjir. Pada tulisan ini peneliti melakukan sesuatu hal yang berbeda dimana konsepnya adalah pencegahan agar bencana banjir berkurang atau seperti kondisi bumi sebelumnya dimana pada wilayah tersebut tidak terjadi bencana banjir.Metode yang dilakukan adalah dengan menangkap jumlah volume air hujan pada suatu DAS (Daerah Aliran Sungai), untuk dihitung berapa jumlah air sebagai penyumbang banjir/ meluapnya air sungai. Untuk itu dibutuhkan suatu sistem informasi berbasis realtime dan online agar mendapatkan data untuk dianalisa sebanyak mungkin.Solusi yang dilakukan adalah menggunakan sumur resapan sebagai salah satu cara pencegahan bencana banjir, untuk mendapatkan nilai yang optimal sebagai solusi banjir maka dilakukan rumus rumus hidrologi serta data-data analisa curah hujan yang sudah ditangkap oleh perangkat monitoring realtime dan berbasis online, agar hasil perhitungan menjadi cukup akurat digunakan metode fuzzy pada tools matlabs.Kata Kunci : Banjir, Bencana Banjir,weather station,zero run off,DAS

Patients submitted to vascular reconstruction may be at high risk of thrombosis, possibly due to an hypercoagulable state and reduction of in and out-flow. The use of drugs to lower this risk has frequently been advocated. In order to reproduce to some extent such a situation, an experimental model was developed and the effect of some dings evaluated. Thrombosis was induced in the femoral artery of 42 dogs by endothelial injury and by reduction of flow and run-off. Twenty four hours later the animals were randomly allocated to one of six treatment groups: control, 2,500 U of subcutaneous heparin each 8 hours, 10 ml/kg of intravenous dextran, 0.5 mg/kg of dipyridamoleeach 8 hours, 0.5 U/kg of bothropase (coagulant fraction of the venom of Bothrops jararacakindly supplied by Dr.G. Rosenfeld), either in one sole dose or each 12 hours. Thirty minutes after treatment being initiated thrombectomy was performed. Arterial permeability was again verified after another 24 hours, by inspection and arteriography. Tests for clotting, fibrinolytic and platelet functions were performed sequentially. At the end of the first step of the experience there was thrombosis and alteration in coagulation and fibrinolysis in 1001 of the animals. After thrombectomy rethrombosis occurred in all animals of the control group. A significant reduction of rethrombosis was observed for the groups treated with dipyridamole and bothropase each 12 hours.

IntroductionThere is controversy in the literature recently regarding the efficacy of rectal non-steroidal anti-inflammatory drugs (NSAID) to prevent post-ERCP pancreatitis (PEP). The aim of this study was to compare the incidence of PEP in three distinct groups of patients at the Royal United Hospital, Bath: no use of rectal diclofenac, selective use and blanket use without contraindication.MethodReadmission data, blood results, radiology reports and discharge summaries were used to identify patients with PEP from August 2010 to December 2015. The administration of rectal diclofenac postprocedure was recorded from the endoscopy reporting system.Results1318 endoscopic retrograde cholangiopancreatographies (ERCP) were performed by four endoscopists during the study period with 66 (5.0%) cases of pancreatitis. 445 ERCPs were performed prior to the introduction of NSAID use during which time, with an incidence of 35 (7.9%) episodes of PEP. During the selective period of NSAID use (high-risk patients) 539 ERCPs were performed and 72 (13.4%) patients received NSAIDs. 17 (3.2%) developed PEP. 334 ERCPs were performed when NSAIDs were given to all patients without contraindication. 289 (86.5%) of patients received rectal diclofenac and 13 (3.9%) developed pancreatitis. There is a statistically significant decrease in PEP comparing the groups of patients receiving NSAIDs selectively (p=0.0009) or routinely (p=0.0172) when compared with none. There is no difference between the selective and routine group (p=0.571).ConclusionOur data demonstrate that the introduction of a selective or routine use of NSAIDs for PEP in a District General Hospital (DGH) significantly decreases the risk of pancreatitis (risk reduction 43.7%).

Introduction: There was a recognized lack of available system for Emergency Physicians (EPs) to communicate their x-ray interpretations to the reading Radiologist; this resulted in unnecessary flagging of cases with significant findings already seen by the EP or the possibility of incorrectly assuming a finding was seen by the EP. Our aim was to develop an IT-based system that permitted Radiologists to view EPs documented x-ray interpretations real-time. Based on engagement with both groups, it was essential that the system be user friendly and not add significantly to an already busy workload. Methods: An online reporting system was introduced in 2011, but with complaints that interpretations were not readily accessible, nor automatic. A revised system was launched in 2014 with 2 improvements: i) EP entered interpretation onto “sticky note” in PACs directly; and ii) EP interpretation “popped up” when a film was opened by Radiologist. Results: Both systems allowed data collection of the percentage of events EPs entered an interpretation. Prior to 2011, 0% of films had EP interpretations available to Radiologist, 33% with initial, and 53% with PACS. The revised system has enabled EPs to enter their x-ray interpretation which has resulted in improvement both subjectively, based on regular feedback from both EPs and Radiologists, and objectively. Conclusion: From this and other quality improvement initiatives, we have learned the importance of engaging frontline practitioners in process changes, specifically the impact on workflow. Also, utilizing existing IT systems and resources can result in positive change with minimal costs.

The critical need to identify children with hearing loss and provide treatment at the earliest possible age has become increasingly apparent in recent years (Northern & Downs, 1978). Reduction of the auditory signal during the critical language-learning period can severely limit the child's potential for developing a complete, effective communication system. Identification and treatment of children having handicapping conditions at an early age has gained impetus through the Handicapped Children's Early Education Program (HCEEP) projects funded by the Bureau of Education for the Handicapped (BEH).
