Estimation of the methane emission factor for the Italian Mediterranean buffalo
In order to contribute to the improvement of the national greenhouse gas emission inventory, this work aimed at estimating a country-specific enteric methane (CH4) emission factor for the Italian Mediterranean buffalo. For this purpose, national agriculture statistics, and information on animal production and farming conditions were analysed, and the emission factor was estimated using the Tier 2 model of the Intergovernmental Panel on Climate Change. Country-specific CH4 emission factors for buffalo cows (630 kg body weight, BW) and other buffalo (313 kg BW) categories were estimated for the period 1990–2004. In 2004, the estimated enteric CH4 emission factor for the buffalo cows was 73 kg/head per year, whereas that for other buffalo categories it was 56 kg/head per year. Research in order to determine specific CH4 conversion rates at the predominant production system is suggested
Shedding Light on Diatom Photonics by means of Digital Holography
Diatoms are among the dominant phytoplankters in the worl's ocean, and their
external silica investments, resembling artificial photonics crystal, are
expected to play an active role in light manipulation. Digital holography
allowed studying the interaction with light of Coscinodiscus wailesii cell wall
reconstructing the light confinement inside the cell cytoplasm, condition that
is hardly accessible via standard microscopy. The full characterization of the
propagated beam, in terms of quantitative phase and intensity, removed a
long-standing ambiguity about the origin of the light. The data were discussed
in the light of living cell behavior in response to their environment
Rodi e Bisanzio a tavola: osservazioni sul fr. 17 K.-A. di Difilo
This article focuses on fr. 17 K.-A. of Diphilus’ Apoleipousa, a dialogue between a cook and his hirer, in which the poet makes fun of the guests from Rhodes and Byzantium, through their favourite food
On the impact of recycling strategies on energy demand and CO2 emissions when manufacturing Al-based components
The industrial world is facing the challenge of reducing emissions by means of energy- and resource-efficient manufacturing
strategies. In some cases, the exerted emissions and the energy demands related to conventional manufacturing processes are not
as intensive as those required to extract and produce the raw materials of which the workpieces are made. Therefore, the
consciousness of the impact of material usage and the eco-informed choice of the end-of-life scenarios are both needed in view
of sustainable development. Aim of this paper is to offer a contribution to a better understanding of the environmental impact of
forming and machining processes, for the production of Al-based components, when varying the aluminum recycling strategy
Polimorfismi biochimici nel sangue e nel latte della capra sarda
The Authors, in a study on 990 individual samples of blood and milk collected from Sardinian goats, have
found the presence of polymorphism at the loci Hb, Tf, X protein, β- Lg, αs-Cn, while the loci Alb, CA, SOD,
α-La, β-Cn were monomorphic

Mapping combined wildfire and heat stress hazards to improve evidence-based decision making
Heat stress and forest fires are often considered highly correlated hazards as extreme temperatures play a key role in both occurrences. This commonality can influence how civil protection and local responders deploy resources on the ground and could lead to an underestimation of potential impacts, as people could be less resilient when exposed to multiple hazards. In this work, we provide a simple methodology to identify areas prone to concurrent hazards, exemplified with, but not limited to, heat stress and fire danger. We use the combined heat and forest fire event that affected Europe in June 2017 to demonstrate that the methodology can be used for analysing past events as well as making predictions, by using reanalysis and medium-range weather forecasts, respectively. We present new spatial layers that map the combined danger and make
suggestions on how these could be used in the context of a Multi-Hazard Early Warning System. These products could be particularly valuable in disaster risk reduction and emergency response management, particularly for civil protection, humanitarian agencies and other first responders whose role is to identify priorities during pre-interventions and emergencies
Testosterone insulin-like effects: an in vitro study on the short-term metabolic effects of testosterone in human skeletal muscle cells
Testosterone by promoting different metabolic pathways contributes to short-term homeostasis of skeletal muscle, the largest insulin-sensitive tissue and the primary site for insulin-stimulated glucose utilization. Despite evidences indicate a close relationship between testosterone and glucose metabolism, the molecular mechanisms responsible for a possible testosterone-mediated insulin-like effects on skeletal muscle are still unknown
