Critical Assessment of Feed-In Tariffs and Solar Photovoltaic Development in Vietnam

2022

Vietnam became the world’s third largest market for solar photovoltaic energy in 2020. Especially after the Vietnamese government issued feed-in tariffs for grid-connected solar photovoltaic systems, the installed capacity of solar photovoltaic applications exploded in 2019. From studies carried out in the relevant literature, it can be said that support policies are highly important for the initial development of the renewable energy industry in most countries. This is especially true in emerging countries such as Vietnam. This paper reviews the feed-in tariffs issued and deployed in different regions of Vietnam for grid-connected solar photovoltaic applications. Moreover, the paper takes …

Geochemical comparison of natural and anthropogenic metal fluxes in extreme environments: Mt. Etna volcano (Italy) and Šalek Valley (Slovenia)

2009

Geochemical comparison between some metals (As, Cd, Cu, Pb, Se, V, Zn) emissions from an active volcano (Mt. Etna) and a highly industrialized area (Šalek Valley) showed some interesting similarities: in general, most of the elements emitted into the atmosphere do not return to the Earth’s surface and are therefore dispersed into the environment. Exceptions for Šalek Valley are Cd, which probably derives in large part from rock leaching, and in part As and Pb, which fall mostly as ash. Also, Etna’s emissions are richer in Cd and Cu, whereas industrial emissions at Šalek Valley are richer in V and Zn. All other metals have similar fluxes in the two types of emissions.

Redox estimates through trace elements partitioning: application on two Italian volcanoes, model comparison and overview on different geodynamic envi…

2021

Oxygen fugacity of Earth’s mantle is one of the most debated issues of petrology. While is evident that the arc-related magmas are more oxidized than MORB and intraplate magmas, however, is not yet possible to produce a model that can uniquely determine this thermodynamic parameter for the depth of the Earth. Furthermore, there is not a clear cause that create this difference of redox conditions between volcanic products. Recently, several experimental models based on the V partitioning between olivine and mafic melt were published and proposed as tools for investigating the redox state of mantle melts for different geodynamic environments. During this PhD we have applied different oxybarom…

Climat et viticulture au Vietnam : évaluation et perspectives

2009

International audience; Parmi les activités humaines, la culture de la vigne pour la production de vin est fortement dépendante des conditions climatiques. Le potentiel d'une zone viticole est sous l'étroite influence du climat, en particulier des conditions radiatives, thermiques et hydriques, de telle sorte que la plupart des vignobles à caractère œnologique sont localisés aux latitudes moyennes. Pourtant, l'expansion de la viti-viniculture aux basses latitudes s'est accélérée ces dernières années. Ici, les conditions climatiques et la faible variation de longueur des jours permettent dans la plupart des cas deux à trois récoltes par an, alors qu'une seule n'est envisageable dans les régi…

International audience; In tropical countries, traditional fermented foods are usually home‐made products obtained through spontaneous fermentation or backslopping. They are now facing an evolution aiming at responding to quality, safety and mass production issues. This requires acquisition of knowledge on raw materials, microbial ecosystems and fermentation processes. Vietnam is a laboratory for such studies as traditional fermented foods play an important role in the diet of Vietnamese and as these foods are very diverse. Among the most popular are nem chua (sausage reminding Thai Nham), dua muoi (cabbage reminding Kimchi), tom chua (shrimps) and the well‐known nuoc mam. The challenge for…

Volcanic signature of volatile trace elements on atmospheric deposition at Mt. Etna, Italy

2009

Volcanic volatiles and aerosol emitted into the atmosphere ultimately fall on the Earth’s surface as wet or dry deposition, and they can influence the environment and the ecosystems at local and regional scales. Therefore, atmospheric deposition plays a key-role in the geochemical cycles, redistributing volcanogenic elements to the ground. For this reason, estimating the volcanogenic trace element fluxes from the atmosphere to the surface is necessary for a better knowledge of the environmental impact of the volcanic emissions. Nevertheless, from a literature review, we have recognized the scarcity of investigation on trace element deposition in the surroundings of active volcanoes. Here, w…
