Il testo letterario nell’insegnamento della lingua e della sociolinguistica russa: il racconto Banja di M. Zoščenko
No full textMonica Perotto presenta l’analisi del racconto “Banja” (Al bagno pubblico, 1924) e di altri racconti
di Michail Zoščenko proposta per la sua rilevanza linguistica e culturologica agli studenti del corso
di Lingua russa LM (corsi di Laurea magistrale in Letterature moderne, comparate e postcoloniali e
Lingua e cultura italiana per stranieri) dell’Università di Bologna. L’autrice ha adottato i modelli di
Pessina, Averjanova, Rogova (1995) e Valgina (2003) per approfondire i vari livelli testuali
nell’indagine macro e microlinguistica. Sono stati particolarmente messi in evidenza i registri
colloquiale/ gergale/ popolare, così come focalizzata l’attenzione sui realia e sugli stereotipi del
periodo sovietico contenuti nel testo. Lo studente di livello avanzato ha potuto quindi sviluppare la
lettura e la comprensione linguistica del testo, nonché le capacità di elaborazione scritta e analisi
stilistica
The Green Hour: Low-emission vehicles, PA-NJ radio broadcast, June 29, 2015
No full textOur society is structured in such a way that most of us are so dependent on cars that it is not easy to simply give them up. But you can make a choice as to what sort of car you have and what level of impact you have on our environment. Do you choose one which gives you 50 mpg or one that gives you 10 mpg? Or is electric? What sort of car do you really need? Listen to the experts as they offer insights on what the best choices available and why.Guests: Michael Thwaite, President of Plug-in America and the NJ Electric Auto Association, and Professor Monica Mazurek of the School of Engineering at Rutgers University.Direct link to broadcast audio,http://www.greenhourradio.com/the-cars-we-drive-say-a-lot-about-us-2/Promo by host (Gery Juleff):You can love your car even more by.......if you make the right choice for your community and the environment.Let’s keep it simple.a Most of us need a car to fully participate in our social and economic environment. And many people enjoy cars.b) But there is a price to pay every time we drive – to our own pocket and to the health of our communities and the environment.c) So we have an obligation to minimize that damage.d) There are many ways in which we can do that, including driving less. But the most important thing we can do is choose a car that does what we need it to do but with the least damage.e) There are many, many options out there for all types of vehicles, from low emission gasoline cars to electric vehicles.f) Find out more on www.greenhourradio.com and listen to our discussion with Michael Thwaite, President of Plug-in America and the NJ Electric Auto Association, and Professor Monica Mazurek of the School of Engineering at Rutgers University on www.panjradio.com all this week at 3 and 6pm or later in the week via the podcast on www.greenhourradio.comg) What are you waiting for?Gery JuleffHost of the 'Green Hour'www.greenhourradio.com [email protected] 529 0149The Green Hour is sponsored by our supporters at Duke Farms.

Study on the use of fleshings-derived collagen in post tanning operations
No full textThe leather industry generates waste either in solid or liquid form. Fleshing, which is integral part of a hide, is removed during leather processing as it is an unwanted material in the final product. For every ton of leather processed, about 100-150 kg of fleshing is generated. An alternative to disposal of these wastes is to reuse them. In this study, an experimental activity research for assessing the feasibility of the reuse of the collagen hydrolizate in the retanning/dyeing/fatliquoring phase was performed. The hydrolyzed collagen, in liquid form, is obtained by alkaline hydrolysis of fleshings. The hydrolizate has been used both in a vegetablechrome retannage/dyeing/fatliquoring and in a vegetable retannage/dyeing/fatliquoring to obtain bovine upper leather. Both in a vegetable-chrome retannage and in a vegetable retannage, the final leathers showed similar properties in terms of physical and technical properties to conventionally processed hides. The results obtained indicate that the use of the collagen hydrolizate in the retanning/dyeing/fatliquoring phase as an interesting route for recovering the fleshings
Leather tanning: Life cycle assessment of retanning, fatliquoring and dyeing
No full textTanneries boost the local economic development, but lead to severe environmental pollution; hence, improving the environmental assessment of this sector is essential. In this paper, the Life Cycle Assessment method was applied to estimate impacts on the environment and human health of retanning, fatliquoring and dyeing. The analysis was performed from a “gate to gate” perspective. Moreover, sulpho chlorinated paraffin and epoxidized vegetable oil have been evaluated as alternative fatliquoring agents. The production of electricity required for the rotation of drums gives the main contribute to most of the impact categories, followed by the azo-dye production. Emissions of sulfur dioxide, nitrogen oxides, manganese, vanadium and nickel associated to power plants are the main sources of terrestrial acidification and particulate matter formation, as well as of human and marine toxicity (4.48·10 −1 and 1.09·10 −2 kg of 1,4-DBeq kg −1 crust leather, respectively). Nitrate loads from wastewater treatment and oxidative treatments affect heavily marine eutrophication (6.9·10 −1 g N eq kg −1 crust leather). The use of epoxidized vegetable oil would affect human toxicity, ecosystem, metal and water resources depletion more than the use of sulpho chlorinated paraffin, mainly due to pesticides distribution and other cultivation practices. Phosphate and nitrate releases due to fertilization determine the high impact on the categories freshwater and marine eutrophication. Progress in increasing the conversion efficiency is demanded, but overall focus must be made on the substitution of fossil fuels with cleaner alternatives. The transition towards a circular economy is encouraged; increasing rates of reduction, reuse, recycle and recover of solid waste and tannery effluents are recommended. Agricultural practices with a reduced consumption of phytosanitary products and mineral fertilizers, alternative to conventional farming, would strongly contribute to increase the sustainability of epoxidized vegetable oil as alternative fatliquoring agent

CO2 capture at high temperature and low concentration on Li4SiO4 based sorbents
No full textSolid sorbents based on lithium orthosilicate (Li4SiO4) have shown promise for CO2 capture at high
temperature. Improved sorption properties can be obtained by appropriate doping. In this study, different
promoted Li4SiO4-based sorbents were prepared by addition of potassium carbonate and binary/ternary
alkali (Li, K and Na) carbonate eutectic mixtures. The CO2 sorption properties of the sorbents were
investigated by thermal gravimetric analysis (TGA) at different temperatures in the range between 500 and
600 °C and at low CO2 partial pressure (0.04 atm). The results showed that all the promoters used
noticeably improved the CO2 sorption capacity in comparison to no-promoted Li4SiO4. At the optimum
sorption temperature of 580 °C, Li4SiO4 with addition of 30 wt% of K2CO3 showed the best CO2 adsorption
proprieties with sorption capacities of 230 mg CO2/g sorbent corresponding to a conversion of about 80 %.
Besides this sample maintained its original capacity during multiple CO2 sorption/desorption cycles
Terbuthylazine and desethylterbutylazine : recent occurrence, mobility and removal techniques
No full textThe herbicide terbuthylazine (TBA) has displaced atrazine in most of EU countries, becoming one of the most regularly used pesticides and, therefore, frequently detected in natural waters. The affinity of TBA for soil organic matter suggests prolonged contamination, once present; degradation leads to the release of the metabolite desethylterbuthylazine (DET), which has a higher water solubility and binds more weakly to organic matter compared to the parent compound, resulting in higher associated risk for contamination of groundwater resources. Additionally, TBA and DET are chemicals of emerging concern because of their persistence and toxicity towards aquatic organisms; moreover, they are known to have significant endocrine disruption capacity to wildlife and humans. Conventional treatments applied during drinking water production do not lead to the complete removal of these chemicals; activated carbon provides the greatest efficiency, whereas ozonation can generate by-products with comparable oestrogenic activity to atrazine. Hydrogen peroxide alone is ineffective to degrade TBA, while UV/H2O2 advanced oxidation and photocatalysis methods are the most effective processes for oxidation of TBA, with efficiencies above 90%. It has been determined that direct photolysis gives the highest degradation efficiency of all UV/H2O2 treatments, while most of the photocatalytic degradation efficiency is attributed to OH radicals, and TiO2 solar-photocatalytic ozonation can lead to almost complete TBA removal in ~30 min. Biomixtures could also be highly effective in preventing groundwater pollution due to TBA and DET, while constructed wetlands provide a valuable buffer capacity, protecting downstream surface waters from contaminated agricultural runoff
