George Box was a British industrial and academic statistician who made seminal contributions to theory and practice in the areas of quality control, time-series analysis, the design of experiments, and Bayesian inference, and was the recipient of many awards and honours. He left school at the age of 16 years and, following his early interest in chemistry, found employment as the assistant to the chemist who managed the local sewage treatment plant. While working at the plant, he enrolled for a chemistry degree course with the University of London's External System, but soon after the outbreak of World War II he joined the army and ceased working on the degree. While in the army he was tasked with conducting biochemical experiments relating to the effects of mustard gas but came to realize that the real expertise required was that of a statistician rather than a chemist. After the war he enrolled at University College London and obtained a BSc in mathematics and statistics. From 1948 to 1956 he was employed as an industrial statistician at Imperial Chemical Industries (ICI). While at ICI he took a year's leave of absence in 1953 to serve as a visiting professor at the North Carolina State University at Raleigh. He then returned to ICI but in 1956 accepted a post at Princeton University as director of the university's Statistical Techniques Research Group. In 1959 he left Princeton for the University of Wisconsin–Madison, where in 1960 he founded the University of Wisconsin's Department of Statistics, retiring as an emeritus professor in 1991. He was a man of great personal humour and warmth who cared deeply about his colleagues and was much loved in return by his many students and collaborators.

Filter Process

A sewage treatment plant is located in the middle of Inner Mongolia. There is a large amount of slaughtering wastewater in the influent with high COD, SS, low annual temperature, poor nitrogen removal effect, and the effluent quality is only grade B. In order to solve the above problems, A\A\O-MBBR + high efficiency sedimentation tank continuous sand filter process was adopted to establish a new anaerobic tank and a first stage AO-MBBR bioreactor. The selection tank and partial oxidation ditch were transformed into the second stage A pool (anoxic pool), and the remaining part of the existing oxidation ditch was transformed into the second stage O pond (aerobic pool), which further removed phosphorus and reduced the SS in the sewage, and solved the problem of low temperature biological treatment in winter in the north of China. The quality of the effluent reached level A after the upgrading.

The aim of this study is to identify the potential risks to the North Station (Beit Lahiya Station and the North Emergency Station), and to prepare emergency response procedures in the sewage treatment plant in Northern Gaza. The researchers followed the descriptive and analytical approach of the sources and reports issued by the institutions related to the sewage stations in the Gaza Strip. The study also included interviews with engineers at the station to analyze and assess the risks to the North station, to identify indicators to prevent flooding of Umm al-Nasr village, and to identify preventive measures to avoid disasters. The study also recommended the necessity of finishing the development of the North Emergency Station Project to accommodate the cumulative increase in the amount of treated water, as well as work on the preparation of contingency plans to deal with the expected risks and the preparation of preparedness and response procedures for each risk.

Vibrio cholerae non-O1 was found throughout the Apalachicola, FL, estuary. V. cholerae O1 was isolated primarily at the City of Apalachicola sewage treatment plant, Scipio Creek and the north shore of St. George Island. Highest concentrations of both serogroups occurred in August and November. Concentrations were lowest in February and increased substantially in May. A cholera toxin-like toxin was not detected in any of the V. cholerae cultures by the Y-1 mouse adrenal cell assay or the enzyme-linked immunosorbent assay (ELISA). However, 35% of the V. cholerae O1 and 22% of the V. cholerae non-O1 cultures selected for testing caused diarrhea in infant rabbits. The proportion of V. cholerae O1 and non-O1 isolates pathogenic to infant rabbits increased as water temperature decreased. Fecal coliforms appeared to be more useful than total coliforms as indicators of the numbers of V. cholerae in water, but neither of those National Shellfish Sanitation Program indicator groups ensured against the presence of pathogenic V. cholerae in shellfish-growing areas.

The purpose of this study was to present a methodology with superior efficiency for inactivating pathogenic indicators commonly found in domestic sewage. The adopted method was based on synergistic effect resulting from the introduction of a UV radiation pre-disinfection stage of sewage followed by secondary treatment. A pilot unit was installed in the sewage treatment plant of the University of São Paulo to simulate the combined system in full-scale operational conditions. Its performance was evaluated through microbiological examinations for determining Escherichia coli, total coliforms and coliphages. The application of UV radiation at 5.1 mW/cm2 for 10 s of exposure in the first disinfection stage was enough to reduce the surviving number of E. coli around 100 times, in comparison to the conventional method. Therefore, based on experimental data, it is possible to conclude that combining treatment and pre-disinfection stage is an effective potential technique to produce effluents with lower degree of contamination by pathogenic organisms.

In this study we have developed an in house capacity at the Chemistry Department, the University of the South Pacific, to analyze methane in ambient air to a precision of 1.5% using a custom converted Gas Chromatograph with FID detector. The technical support to develop this capacity was provided by our overseas partner, National Institute of Water and Atmospheric Research (NIWA). The air samples were collected from known sources of methane such as the digester at the sewage treatment plant, rubbish dump, wetlands, sugar cane burning in the western side of Viti Levu, geothermal emission in Vanua Levu, rice farms and cattle farms from September 2001 to June 2002 and were analyzed. Through inter-laboratory measurements involving NIWA a mean drift of 0.8% was obtained. The methane concentration in the ambient air has a seasonal cycle with a minimum during late January and a maximum during the July to August period. The digester at the sewage plant recorded the maximum concentration of approximately 70 ppmv followed by Lami rubbish dump with values ranging from 4.37 ? 13.35 ppmv. The data from cattle farms, wetlands, rice farms and hot springs recorded emissions in the range of 2.00 ? 5.11 ppmv, 1.85 ? 4.25 ppmv, 1.77 ? 2.62 ppmv and 2.06 ? 1.90 ppmv respectively.

Poland's accession to the European Union contributed to the infrastructure development of the whole country. One of the elements of the modernized infrastructure is the sewage network and facilities on this network, as well as facilities for waste water treatment and disposal of sludge. A wide stream of funds flowing to the country, and consequently also to the north-eastern polish voivodeships (Podlaskie, Warmian-Masurian, Lublin), allowed modernization, organize, and sometimes to build a new sewage management of this part of the country. The main factors and parameters that allow us to evaluate the development of the sewage management in north-eastern Poland are included: percentage of population using sewage treatment plants, number of municipal sewage plants with the division of their type, number of industrial plants, number of septic tanks, amount of sewage purified in a year, amount of sludge produced in the year, design capacity of sewage treatment plant, size of plant in population equivalent (PE). From a number of investments in the field of wastewater management carried out in the discussed area in the period after Poland's accession to the European Union, 9 investments were considered the most important, 3 from each of the voivodeships.

A large number of fossil-rich beds have been located from over 30 km along the Tours-Poitiers High Speed Line (LGV) during earthworks prior to its construction, and in particular amber was collected from Scorbé-Clairvaux (locality of La Bergeonneau) to the north of Poitiers. The paper describes also amber pieces from Châtellerault (locality of La Désirée) discovered during the development of sewage treatment plant along the Vienne river. Lower Cenomanian shelly sandstones and siltstones of Scorbé-Clairvaux contain rare amber pieces associated with seed plants (Frenelopsis sp., Nehvizdya sp., and angiosperm seeds) and a diversified fauna, composed of micro-remains of 27 taxa, comprising elasmobranchs (Haimirichia amonensis Cappetta and Case, 1975, Protolama sp. and Squalicorax sp.), actinopterygians (Enchodus sp. and Pycnodontidae), reptiles including vertebrae the marine snake Simoliophis rochebrunei Sauvage, 1880, some rare helochelydrid plates (cf. Plastremys), teeth of three crocodilian families (Atoposauridae, Goniopholididae and Bernissartiidae) and an undetermined dinosaurian long bone fragment.
