Reaching for net zero: The impact of an innovative university-led business support programme on carbon management strategy and practices of small and medium-sized enterprises

Small and medium-sized enterprises (SMEs) are at the heart of the economy, representing the majority of businesses in the United Kingdom and the European Union, and employ a high percentage of people. With this positive impact comes an environmental footprint. SMEs account for around half (43–53%) of the greenhouse gas emissions, yet typically, they lack the support that larger organisations have in-house and are often hard to reach in terms of engagement, policy and practical interventions. SMEs face a range of barriers to implementing carbon management and are still a misunderstood sector both in their approach to carbon management and how best to provide business support for change. This research addresses that challenge by investigating the impact of an innovative university-led business support programme to help SMEs develop a carbon management strategy and practices. The research adopted a quantitative approach with a pre- and post-intervention survey to gather data from 101 SMEs in the context of the Sustainability in Enterprise (SiE) programme at Nottingham Trent University, United Kingdom. The study shows that universities have an important role, and the SiE programme had a significant impact on SMEs' transition to net zero through policy and strategy development, resource monitoring, carbon footprinting, target setting and carbon management maturity. The research highlights the importance of business support for SMEs, specifically in carbon management, while segmenting based on size and sector to meet ambitious local, national and global net zero targets

State of the climate in 2013

In 2013, the vast majority of the monitored climate variables reported here maintained trends established in recent decades. ENSO was in a neutral state during the entire year, remaining mostly on the cool side of neutral with modest impacts on regional weather patterns around the world. This follows several years dominated by the effects of either La Niña or El Niño events. According to several independent analyses, 2013 was again among the 10 warmest years on record at the global scale, both at the Earths surface and through the troposphere. Some regions in the Southern Hemisphere had record or near-record high temperatures for the year. Australia observed its hottest year on record, while Argentina and New Zealand reported their second and third hottest years, respectively. In Antarctica, Amundsen-Scott South Pole Station reported its highest annual temperature since records began in 1957. At the opposite pole, the Arctic observed its seventh warmest year since records began in the early 20th century. At 20-m depth, record high temperatures were measured at some permafrost stations on the North Slope of Alaska and in the Brooks Range. In the Northern Hemisphere extratropics, anomalous meridional atmospheric circulation occurred throughout much of the year, leading to marked regional extremes of both temperature and precipitation. Cold temperature anomalies during winter across Eurasia were followed by warm spring temperature anomalies, which were linked to a new record low Eurasian snow cover extent in May. Minimum sea ice extent in the Arctic was the sixth lowest since satellite observations began in 1979. Including 2013, all seven lowest extents on record have occurred in the past seven years. Antarctica, on the other hand, had above-average sea ice extent throughout 2013, with 116 days of new daily high extent records, including a new daily maximum sea ice area of 19.57 million km2 reached on 1 October. ENSO-neutral conditions in the eastern central Pacific Ocean and a negative Pacific decadal oscillation pattern in the North Pacific had the largest impacts on the global sea surface temperature in 2013. The North Pacific reached a historic high temperature in 2013 and on balance the globally-averaged sea surface temperature was among the 10 highest on record. Overall, the salt content in nearsurface ocean waters increased while in intermediate waters it decreased. Global mean sea level continued to rise during 2013, on pace with a trend of 3.2 mm yr-1 over the past two decades. A portion of this trend (0.5 mm yr-1) has been attributed to natural variability associated with the Pacific decadal oscillation as well as to ongoing contributions from the melting of glaciers and ice sheets and ocean warming. Global tropical cyclone frequency during 2013 was slightly above average with a total of 94 storms, although the North Atlantic Basin had its quietest hurricane season since 1994. In the Western North Pacific Basin, Super Typhoon Haiyan, the deadliest tropical cyclone of 2013, had 1-minute sustained winds estimated to be 170 kt (87.5 m s-1) on 7 November, the highest wind speed ever assigned to a tropical cyclone. High storm surge was also associated with Haiyan as it made landfall over the central Philippines, an area where sea level is currently at historic highs, increasing by 200 mm since 1970. In the atmosphere, carbon dioxide, methane, and nitrous oxide all continued to increase in 2013. As in previous years, each of these major greenhouse gases once again reached historic high concentrations. In the Arctic, carbon dioxide and methane increased at the same rate as the global increase. These increases are likely due to export from lower latitudes rather than a consequence of increases in Arctic sources, such as thawing permafrost. At Mauna Loa, Hawaii, for the first time since measurements began in 1958, the daily average mixing ratio of carbon dioxide exceeded 400 ppm on 9 May. The state of these variables, along with dozens of others, and the 2013 climate conditions of regions around the world are discussed in further detail in this 24th edition of the State of the Climate series. © 2014, American Meteorological Society.

Perfil de sensibilidade aos antimicrobianos e eficácia de sanitizantes frente aos isolados de Salmonella spp. oriundos de carcaças suínas no Rio Grande do Sul

Os objetivos do trabalho foram avaliar o perfil de sensibilidade a antimicrobianos e a eficácia de três sanitizantes frente a isolados de Salmonella spp. oriundos de carcaças na tecnologia de abate de suínos. Avaliaram-se 120 amostras, das quais 39 foram positivas para Salmonella spp. Os princípios ativos testados foram penicilina G 10 U, amoxicilina + ácido clavulânico 30mcg, ampicilina 10mcg, cloranfenicol 30mcg, tetraciclina 30mcg, estreptomicina 10mcg, neomicina 30mcg, gentamicina 10mcg, enrofloxacina 5mcg, sulfazotrim 25mcg, sulfonamida 300mcg e trimetropima 5mcg. Nos testes com sanitizantes utilizaram-se clorexidina, amônia quaternária e ácido peracético com tempos de contato de um, cinco, 10 e 15 minutos. Os índices de resistência aos antimicrobianos foram de 100% para penicilina, 94,9% para tetraciclina, 89,7% para trimetropima e 87,2% para ampicilina. Nenhum dos princípios ativos foi 100% eficaz frente aos isolados testados, observando-se melhor ação para amoxicilina+ácido clavulânico (86,7%), neomicina (86,7%) e cloranfenicol (64,1%). Nos testes de eficácia dos sanitizantes, o ácido peracético a 0.5% foi efetivo a partir de 10 minutos (94,6%) e 15 minutos (97,3%) de contato; amônia quaternária a 1% por 10 minutos (89,2%) e 15 minutos (97,3%) e clorexidina a 0.5% por 10 minutos (70,3%) e 15 minutos de contato (72,8%). Todas as amostras testadas apresentaram multirresistência e seis (15,3%) apresentaram resistência à ampicilina, cloranfenicol, estreptomicina, sulfonamida e tetraciclina (denominado grupo ACSSuT), indicando a necessidade de monitorar a propagação da resistência aos antimicrobianos em Salmonella spp. oriundas de suínos. O sanitizante mais efetivo frente aos isolados testados foi o ácido peracético a 0.5% por 15 minutos, reforçando a necessidade de monitorar também a efetividade de produtos sanitizantes frente aos isolados de Salmonella spp

Production of pions, kaons and protons in pp collisions at s=900\sqrt{s}=900 GeV with ALICE at the LHC

The production of $\pi^+$, $\pi^-$, $K^+$, $K^-$, p, and pbar at mid-rapidity has been measured in proton-proton collisions at $\sqrt{s} = 900$ GeV with the ALICE detector. Particle identification is performed using the specific energy loss in the inner tracking silicon detector and the time projection chamber. In addition, time-of-flight information is used to identify hadrons at higher momenta. Finally, the distinctive kink topology of the weak decay of charged kaons is used for an alternative measurement of the kaon transverse momentum ($p_{\rm T}$) spectra. Since these various particle identification tools give the best separation capabilities over different momentum ranges, the results are combined to extract spectra from $p_{\rm T}$ = 100 MeV/$c$ to 2.5 GeV/$c$. The measured spectra are further compared with QCD-inspired models which yield a poor description. The total yields and the mean $p_{\rm T}$ are compared with previous measurements, and the trends as a function of collision energy are discussed.Comment: 24 pages, 18 captioned figures, 5 tables, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/388
