Wind and solar energy: a comparison of costs and environmental impacts
Carnevale, Ennio A.,Lombardi, Lidia,Zanchi, Laura Techno-Press 2016 Advances in energy research Vol.4 No.2
This study is concerned with the analysis of two renewable technologies for electric energy production: wind energy and photovoltaic energy. The two technologies were assessed and compared by economic point of view, by using selected indicators characterized by a clear calculation approach, requirement of information easy to be collected, clear, but even complete, interpretation of results. The used economic indicators are Levelized Cost of Energy, $CO_2$ abatement cost and fossil fuel saving specific cost; these last two specifically aimed at evaluating the different capabilities that renewable technologies have to cut down direct $CO_2$ emissions and to avoid fossil fuel extraction. The two technologies were compared also from the environmental point of view by applying Life Cycle Assessment approach and using the environmental impact categories from the Eco-indicator'95 method. The economic analysis was developed by taking into account different energy system sizes and different geographic areas in order to compare different European conditions (Italy, Germany and Denmark) in term of renewable resource availability and market trend. The environmental analysis was developed comparing two particular types of PV and wind plants, respectively residential and micro-wind turbine, located in Italy. According to the three calculated economic indicators, the wind energy emerged as more favorable than PV energy. From the environmental point of view, both the technologies are able to provide savings for almost all the considered environmental impact categories. The proposed approach, based on the use of economic and environmental indicators may be useful in supporting the policies and the decision making procedures concerned with the promotion and use of renewables, in reference to the specific geographic, economic and temporal conditions.

Effect of Laser Microcutting on Thermo-Mechanical Properties of NiTiCu Shape Memory Alloy
Carlo Alberto Biff,Paola Bassani,Marco Carnevale,Nora Lecis,Antonietta Loconte,Barbara Previtali,Ausonio Tuissi 대한금속·재료학회 2014 METALS AND MATERIALS International Vol.20 No.1
The machining of shape memory alloys (SMAs), such as NiTi based alloys, is a very interesting and rele-vant topic for several industrial applications in the biomedical, sensor and actuator fields. Laser technology isone of the most suitable methods for the manufacturing of products in the aforementioned fields, mainlywhen small and precise features have to be included. Due to the thermal nature of this process, study of itseffect on the functional properties of these materials is needed. Except for binary NiTi, few results on thelaser machining of NiTi based alloys are available in the literature. In this work, thin sheets of Ni40Ti50Cu10(at.%) were processed by a fibre laser and the effect of process speed on the material properties was analy-sed. Scanning electronic microscopy was adopted for observation of the laser cut edges’ morphology. Chemi-cal composition of the processed material was evaluated by energy dispersion spectroscopy and nanohardnessmeasurements were used to estimate the heat affected zone. SMA functional properties were studied on bothbase and laser machined material. These characteristics are affected by laser machining for the presence ofmelted material; this effect can be minimised by increasing the laser process speed.

Background: The aim of this study is to illustrate the historical role of the International Commission on Occupational Health (ICOH) congresses as an arena where national and international occupational medicine can dialogue and as the first example of scientific transferability of the research and prevention results that have had such an impact on global public health. Methods: We used the ICOH Heritage Repository, in which ICOH congress proceedings (from the first congress in Milan in 1906 to the last congress, held in Dublin in 2018), are organised in an orderly way, updated and easily accessible according to open access logic. Results: We describe studies by three physicians who submitted significant scientific work to ICOH congresses, one on the battle against ancylostomiasis (Volante, 1906), the second (Quarelli, 1928) on carbon disulphide poisoning, and the third (Viola, 1969) on the carcinogenicity of vinyl chloride monomer. Priority is given to Italian cases, on account of the authors' obvious familiarity with the issues. Conclusion: The visibility offered in ICOH conferences and their published proceedings has boosted the international spread of their findings, contributing to the scientific transferability of the research results and influencing the development of policies and prevention interventions that have had a great impact on global public health.

Background: The prevalence of nonalcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus (T2DM) ishigh, though its severity is often underestimated. Our aim is to provide an estimate of the prevalence of severe NAFLD in T2DMand identify its major predictors. Methods: T2DM patients (n=328) not previously known to have NAFLD underwent clinical assessment, transient elastographywith measure of liver stiffness (LS) and controlled attenuation parameter (CAP), and genotyping for patatin like phospholipasedomain containing 3 (PNPLA3) and 17β-hydroxysteroid-dehydrogenase type 13 (HSD17B13). Results: Median LS was 6.1 kPa (4.9 to 8.6). More than one-fourth patients had advanced liver disease, defined as LS ≥7.9 kPa(n=94/238, 29%), and had a higher body mass index (BMI) than those with a LS <7.9 kPa. Carriage of the G allele in the PNPLA3gene was associated with higher LS, being 5.9 kPa (4.7 to 7.7) in C/C homozygotes, 6.1 kPa (5.2 to 8.7) in C/G heterozygotes, and6.8 kPa (5.8 to 9.2) in G/G homozygotes (P=0.01). This trend was absent in patients with ≥1 mutated HSD17B13 allele. In a multiplelinear regression model, BMI and PNPLA3 genotype predicted LS, while age, gender, disease duration, and glycosylated hemoglobindid not fit into the model. None of these variables was confirmed to be predictive among carriers of at least one HSD17B13mutated allele. There was no association between CAP and polymorphisms of PNPLA3 or HSD17B13. Conclusion: Advanced NAFLD is common among T2DM patients. LS is predicted by both BMI and PNPLA3 polymorphism,the effect of the latter being modulated by mutated HSD17B13.
