Wave and Wind Energy Systems Integration in Vietnam: Analysis of Energy Potential and Economic Feasibility

2020

Vietnam energy demand is currently growing at a very high annual rate, with the government being very interested in investments in renewable energies. Since the region with the highest solar and wind potential is far away from the big load centers, an investigation of offshore energy resources is here proposed. In this study, a review of previous energy potential assessments is provided. Moreover, the minimum feed-in-tariff to make the investments profitable is evaluated, showing that the current tariff for offshore wind plants is largely unattractive.

Introduction of Offshore Wave, Wind and Solar Energies in Vietnam

2020

In Vietnam, the energy demand shows an ever-increasing trend. To limit the utilization of fossil fuels and the following consequences for the environment, renewable energy sources must be adopted. In this context, the paper assesses the utilization of offshore wind and sea wave, by considering a commercial wind turbine and a prototypical wave energy converter. Solar energy can be optionally also collected by this device. An algorithm is introduced to find the best composition of the three sources able to cover a desired share of energy demand. The approach is applied to Ca Mau, a province in the southern part of Vietnam. Finally, the results encourage the adoption of these energy sources th…

The beginning of the Neolithic in Southern Italy and Sicily

2018

Abstract The process of Neolithization of Southern Italy and Sicily covers about 500 years (6200–5700 cal BC) and involves two cultural horizons: Archaic Impressed Ware or “Impresse Arcaiche” and Advanced Impressed Ware or “Impresse Evolute”. In Southern Italy the Neolithic peopling from the East is characterized by a “package” of plenty domesticated plants and livestock; in Sicily the adoption of the new economical system is apparently more slow and with no evidences of ruptures between the Mesolithic groups and first farmers. In this paper we present the chronological and cultural framework of the sixth millennium BC within the area of investigation, with an up-to-date bibliography about …

Fotografia e cultura visuale: una grammatica della modernità

2022

Visual culture studies and photography are the keywords for understanding the contemporary, the age of digital images. The aim of this paper is to verify the role of photography in order to give form and meaning to the experience.

Recurrent Mesolithic–Neolithic occupation at Sise (western Latvia) and shoreline displacement in the Baltic Sea Basin

2016

A major assemblage of Mesolithic and Neolithic wooden artefacts has been recovered from the bed of the River Užava at Sise, in the coastal belt of western Latvia. New archaeological investigation has also produced wooden remains and other evidence of occupation on the riverbank. On the basis of multi-proxy environmental data and radiocarbon dating, this article offers a first attempt to place the human activity in a palaeolandscape context. The earliest evidence of human presence is provided by wooden artefacts dated to c. 10,500–9700 cal. BP, during the Ancylus Lake transgression. These remains are thought to reflect fishing activities in the shallows of the Ventspils Bay, which existed d…

An exceptional rocky shore preserved during Oligocene (Late Rupelian) transgression in the Upper Rhine Graben (Mainz Basin, Germany)

2012

The Early Oligocene (Late Rupelian) Alzey Formation (Mainz Basin, Upper Rhine Graben, Germany) records the development of a rocky coast depositional system during transgression. The formation unconformably overlies Permian bedrock across a composite transgressive ravinement surface. Exposure of the surface shows a succession of subplanar bedrock terraces, separated by near-vertical risers. Terraces show a broad staircase geometry and display wave-erosional features (notches, sea stacks, furrows). Detailed sedimentological and palaeoecological investigations reveal prograding beachface and shoreface depositional units that overlie terraces and are adjacent to risers. Terraces are interpreted…

Testing heterogeneity in faunal assemblages from archaeological sites. Tumbling and trampling experiments at the early-Middle Pleistocene site of Ges…

2010

Abstract The current paper reports an experimental case study to test the heterogeneity of faunal assemblages from the Early-Middle Pleistocene Layers V-5 and V-6 of the Gesher Benot Ya’aqov Acheulian site (Israel). Tumbling and trampling experiments were initiated to gain qualitative insight into processes of bone modification and to assess the timing of the biostratonomic chronology, as it was assumed that both mechanisms were responsible for the formation of striations documented on the bone surfaces from the site. The tumbling experiments mimicked sediment movement in a calm lacustrine shoreline environment whereas the trampling experiments investigate the role of animal/hominin activit…

Land Use History and Site Formation Processes at the Punic Site of Pauli Stincus in West Central Sardinia

2013

The site of Pauli Stincus is located near the town of Terralba, on the inland shores of the Gulf of Oristano in west central Sardinia, Italy, and was occupied between the mid-4th and the late 2nd century B.C. The site and its surroundings were the object of a joint archaeopedological and geomorphological study, which complemented the data from archaeological excavations. This study allowed us to evaluate the suitability of the different landscape and soil components for crop production in the Punic period. The discovery of a buried plow soil at the site's edge enabled us to identify a set of agricultural practices carried out by Punic farmers. These included the removal of sandy topsoil to …

Geomorphological evolution of the River Loukkos estuary around the Phoenician city of Lixus on the Atlantic Littoral of Morocco

2009

The ancient city of Lixus, today situated on a hill on the right bank of the River Loukkos, 4km from the coast, was founded on the shore of a brackish lagoon that was sheltered from Atlantic storms. This geographical context provided the city with one of the best Phoenician harbors and abundant fishing resources, and allowed access to the Gharb cattle farming resources and cereal production systems. In this study, the historical evolution of the Loukkos estuarine environment is reconstructed through geomorphological and sedimentological analyses, combined with cartographic, archaeological, and geographical data. The outcomes reveal the progressive infilling of the estuarine lagoon of Lixus …
