A framework for downscaling precipitation from RCM projections to the high resolutions in time and space required in the urban hydrological climate change impact assessment is outlined and demonstrated. The basic approach is that of Delta Change, developed for both continuous and event-based applications. In both cases, Delta Change Factors (DCFs) are calculated which represent the expected future change of some key precipitation statistics. In the continuous case, short-term precipitation from climate projections are analysed in order to estimate DCFs associated with different percentiles in the frequency distribution of non-zero intensities. The DCFs may then be applied to an observed time series, producing a realisation of a future time series. The event-based case involves downscaling of Intensity-Duration-Frequency (IDF) curves based on extreme value analysis of annual maxima using the Gumbel distribution. The resulting DCFs are expressed as a function of duration and frequency (i.e., return period) and may be used to estimate future design storms. The applications are demonstrated in case studies focusing on the expected changes in short-term precipitation statistics until 2100 in the cities of Linz (Austria) and Wuppertal (Germany). The downscaling framework is implemented in the climate service developed within the EU-project SUDPLAN. © 2012 by the authors.

Dr. Stefana Pecher and her professional medical team at The Country Doc Wellness Center in North Stonington, Ct. announced today that she has implemented MMJ Technologies, the cannabis industry's first-of-its-kind medical marijuana study technology for her Connecticut and Rhode Island patients. Dr. Pecher, understanding the need to responsibly recommend medical marijuana, document, and remotely manage patients' symptoms, was excited about the new MMJ technology and hopes that other healthcare professionals will use the technology in order to better advise patients who would benefit from the use of medical cannabis via such MMJ technology solutions. (http://www.medicalmarijuanadocconnecticut.com) Former FDA head from 1990 to 1997 Dr. David Kessler conceded during a CBS News interview that there is a serious opioid epidemic, adding: “This has been one of the great mistakes of modern medicine.” Dr. Kessler called it “…an American condition. This is an American disease.” (Source) Dr. Pecher noted that many people die daily from opioid pain killer overdoses. Eighty percent (80%) of heroin addicts were once prescribed opioid drugs for legitimate pain concerns. One of Dr. Pecher’s concerns is that opioids are not as helpful for chronic pain as most may think. As one’s tolerance to an opioid drug increases, the demand for higher doses with more prescriptions involving other pain killers becomes a necessity that invites addiction. Using CDC statistics, Dr. Pecher revealed that opioid drug sales quadrupled in the decade between 1999 and 2010. Not surprisingly, the death rate from prescription pain killers also quadrupled during that time. As those drugs filter out into the populace, more people take them non-medically, especially teenagers. In the USA, one in 20 over 12 years of age used opioid pain killers non-medically during 2010. Almost 7,000 people are treated by emergency facilities in the U.S. daily for overdosing opioid pain killers or using them in a manner other than directed. Nearly half of opioid users who go for 30 days or more wind up taking opioid drugs for another three years and beyond. Dr. Pecher explained that two major studies have shown no positive long-term pain relief from opioid use for chronic pain compared to placebo. Conversely, many studies confirm opioid side effects ranging from addiction to death by overdose, usually by respiratory or cardiac compromise. The open window of opioid pain relief is small. As the diminishing pain relief demands increased opioid use, the threshold for overdose is rapidly approached. The success rate from conventional opioid withdrawal strategies is marginal at best. Dr. Pecher mentioned an Israeli clinic that had a 70 percent successful opioid-addiction treatment plan utilizing medical marijuana. Patients were opioid-free within seven months with no adverse symptoms. This is much more optimistic than the 8 percent success rate achieved utilizing other “standard” methods of opioid treatment bolstered by pharmaceuticals that have their own side effects. Where states have legally authorized medical marijuana use, opioid overdose declined on an average of 25 percent. For this reason, Dr. Pecher would like to see more physicians who reside in states that have legalized medical marijuana understand her methods of gradually and safely substituting medical cannabis for opioid painkillers while using the MMJ technology as a tool for monitoring the patient population's health and therapeutic outcomes.

As part of a research & development project commissioned by the Land of North Rhine-Westphalia's Ministry for the Environment and Nature Conservation, Agriculture and Consumer Protection (MUNLV) an examination is being carried out of the general possibilities for centralised and decentralised treatment storm water runoff to be discharged into (canalised) receiving waters and the costs ensuing from this. The examination of the different options is being carried out under real conditions, with the Briller Creek (Wuppertal/Germany) and Müggen Creek (Remscheid/Germany) catchment areas being used as models. The range of investigations deals with a comparison between 'decentralised, semicentralised, centralised' storm water treatment, centralised storm water treatment involving a separate sewer and parameter-specific pollution based storm water runoff control. In the framework of the research project each of the variants is to be elaborated and the costs are to be calculated so as to permit a comparison between the different system designs. In particular, the investigations are to take into account the actual requirements to be met by storm water drainage systems involving separate sewage systems. © IWA Publishing 2011.

A major drawback of separate sewer systems is the occurrence of illicit connections: unintended sewer cross-connections that connect foul water outlets from residential or industrial premises to the storm water system and/or storm water outlets to the foul sewer system. The amount of unwanted storm water in foul sewer systems can be significant, resulting in a number of detrimental effects on the performance of the wastewater system. Efficient removal of storm water inflows into foul sewers requires knowledge of the exact locations of the inflows. This paper presents the use of distributed temperature sensing (DTS) monitoring data to localize illicit storm water inflows into foul sewer systems. Data results from two monitoring campaigns in foul sewer systems in the Netherlands and Germany are presented. For both areas a number of storm water inflow locations can be derived from the data. Storm water inflow can only be detected as long as the temperature of this inflow differs from the in-sewer temperatures prior to the event. Also, the in-sewer propagation of storm and wastewater can be monitored, enabling a detailed view on advection. © IWA Publishing 2013.
