Bibliometric analysis of publications by South African viticulture and oenology research centres
2012
We analysed the production, impact factor of, and scientific collaboration involved in viticulture and oenology articles associated with South African research centres published in international journals during the period 1990–2009. The articles under scrutiny were obtained from the Science Citation Index database, accessed via the Web of Knowledge platform. The search strategy employed specific viticulture and oenology terms and was restricted to the field ‘topic’. The results showed that 406 articles were published during the review period, with the most number of publications being in the South African Journal of Enology and Viticulture (n = 34), American Journal of Enology and Vit…
Shallow water marine sediment bacterial community shifts along a natural CO2 gradient in the Mediterranean Sea off Vulcano, Italy.
2014
The effects of increasing atmospheric CO2 on ocean ecosystems are a major environmental concern, as rapid shoaling of the carbonate saturation horizon is exposing vast areas of marine sediments to corrosive waters worldwide. Natural CO2 gradients off Vulcano, Italy, have revealed profound ecosystem changes along rocky shore habitats as carbonate saturation levels decrease, but no investigations have yet been made of the sedimentary habitat. Here, we sampled the upper 2 cm of volcanic sand in three zones, ambient (median pCO(2) 419 mu atm, minimum Omega(arag) 3.77), moderately CO2-enriched (median pCO(2) 592 mu atm, minimum Omega(arag) 2.96), and highly CO2-enriched (median pCO(2) 1611 mu at…
Diuron environmental levels effects on marine nematodes: Assessment of ecological indices, taxonomic diversity, and functional traits
2021
Abstract Coastal marine systems are the most sensitive zones to emerging pollutants. The present study aims to investigate the effect of Diuron on the meiofaunal assemblages, collected from the Bizerte channel (Tunisia). Microcosm experiments were set up using four increasing Diuron concentrations [D1 (10 ng g−1 dry weight (DW)), D2 (50 ng g−1 DW), D3 (250 ng g−1 DW) and (1250 ng g−1 DW)] compared to non-contaminated sediments (controls) and all plots were incubated for 30 days. Our results show that Diuron-supplemented sediments provoked the significant decrease of meiofaunal abundance as well as a change in nematodes' diversity and structure composition. All univariate indices, as well as…
Foster Carbon-Neutrality in the Built Environment: A Blockchain-Based Approach for the Energy Interaction Among Buildings
2022
Decarbonizing urban environments and reducing their energy consumption is one of modern society biggest commitments. In this regard, both the scientific community and international governments have been giving special consideration on improving the energy-environmental performance of mostly single buildings; recently the focus has been shifting towards a broader Positive Energy District (PED)/ Energy Community (EC) vision, from small clustered group of buildings to neighborhoods up until urban settlements. In this respect, integrating the use of renewable energy resources (RES) and actively involving building users can have a significant environmental impact on local areas. Within this fram…
Challenges and directions for Blockchain technology applied to Demand Response and Vehicle-to-Grid scenarios
2021
Abstract Nowadays, Blockchain is considered a consolidated technology supporting many different applications that integrate well with Artificial Intelligence and the Internet of Things, and supports the creation of Decentralized Autonomous Organizations. Within this wider framework, the energy blockchain applications are now deserving more and more attention, since blockchain architectures, on one hand, provide transparency and solve the information asymmetry problem, on the other, provide disintermediation. In this way, the dream of an energy market closer to end-users becomes a reality, although, still, the regulatory framework is not clear, especially for what concerns the tokenization o…
Ecotourism in Bolivia : an ethnographical study of ecotourism impacts in Madidi National Park
2016
Master thesis development management - University of Agder 2016 The concepts of ecotourism are widely defined but it is often used as a marketing instrument in order to promote tourism businesses related to nature. Ecotourism experience a fast growth in world tourism industry and many developing countries are trying to use ecotourism as a tool to achieve sustainable development. Ecotourism provides many beneficiaries to local environments, economies and socio-cultural lives. However, ecotourism may as well have harmful effects on those involved. Still, ecotourism conserves and protects local areas and its people. Madidi National Park in Bolivia has been estimated to be one of the world’s mo…
Civic resielience : botanical gardens in North America, birth, development, and enviromental awarness
2023
The chapter explores from a historical perspective the birth of botanical gardens in North America, considered a significant part of the ecological network system and of the green and blue 'infrastructure'. This important system opposes geographical risk, which must be organically dealt with in programmes, plans and strategies that protect the landscape, prevent risks, and strengthen short-, medium- and long-term actions, also involving local Communities, integrating the vision to the different scales of intervention and projects. The Botanical Garden, seen here as an 'Open Work', has an important role not only because it preserves botanical specimens that come from all over the world, but …
“The war is over”. Militarizing the language and framing the Nation in post-Brexit discourse
2020
This chapter analyzes the militarization of political language in digital contexts in the post-Brexit discourse, and how such militarization, which is often constitutive of hate speech, contributes to framing an “exclusive” concept of the nation whose meaning is reproduced and circulated (as well as challenged) in society. It will address the role of emotions and hate in language in fueling and aggregating online communities around a key political issue, i.e. the Brexit negotiations, and a core cultural and social concept, i.e. the nation. The militarization of language, which is based on certain discursive structures, e.g. war metaphors (Lakoff and Johnson 1980, Musolff 2020), is one of th…

2003
Kas ir ZĪME? ZĪME ir datu kopu standartizēta grafiska reprezentācija. ZĪME sastāv no diviem grafiskiem elementiem: (1) Sieta elementa un (2) Koda elementa. Sieta elementu konfigurācija ir nemainīga. Koda elementu konfigurācija mainās saskaņā ar ievadītajiem datiem. The Anatomy of ZIME What is ZIME? ZIME is a standardized graphical representation of data sets. ZIME is built of two graphical elements: (1) Sieve element and (2) Code element. Sieve elements have always the same configuration, while Code elements are configured according to the input data.
EVALUATION OF AEROBIC AND ANAEROBIC BACTERIAL DECHLORINATION POTENTIAL OF A 1,2-DICHLOROETHANE CONTAMINATED AQUIFER
2023
Chlorinated solvents, belonging to the class of chlorinated aliphatic hydrocarbons (CAHs), are synthetic organohalide chemicals frequently found as contaminants of groundwater and soil, due to their widespread use in several industrial processes and improper disposal methods. These compounds pose serious health threats because of their toxic and sometimes carcinogenic effects. Among these compounds, 1,2-dichloroethane (1,2-DCA) is one of the most common aquifer contaminants, considered toxic and classified as a possible human carcinogen. Remediation approaches toward these contaminants include conventional cleanup technologies based on physical/chemical methods, and bioremediation, consider…
