The lithic site Boa Esperança II (BES II), in the São Paulo segment of the Brazilian Plateau, next to the boundary between the cities of Araraquara (SP) and Boa Esperança do Sul (SP), presents a collection of almost 2,000 lithic artifacts (predominantly chert and sandstone), being interpreted as a settlement of diversified functions with possibly continuous or successive occupation. In this work, we approach the site based on interface of its insertion in the regional physical-environmental context - with emphasis on the interface with relief frames, surface structure study and estimated geomorphic sequences of the alluvial plain of Jacaré-Guaçu river - and techno-typological analysis. It was verified that the BES II artifacts are distributed along vertical profiles and relief pictures lined by records that mark the transition from semi-arid conditions to others of increasing humidity, successive oscillations of base levels and modifications of fluvial regimes (ephemeral channels passing to perennial channels of different hydrological meandrings patterns), indicating that human occupation has dealt with conditions of quite distinct landscapes between the Late Pleistocene and the Holocene. Local lithic industry would have taken advantage of attributes derived from these modifications in the landscape over time - in particular the exposure of gravels of large river pebbles deposited by torrential ephemeral channels. The past  abundance of raw material of fluvial origin would have contributed to the location of the site in the regional geomorphological context, as well as for a lithic assemblage based on the production of large unipolar flakes. We observed in the correlations between the position of artifacts, geomorphical and pedological data, OSL and Carbone-14 dates at archaeological levels, elements that allow us to discuss considering BES II as an archaeological site to integrate the interval of the Pleistocene-Holocene transition and to had interfaces with the geomorphological and environmental changes of such time. The archaeological implications of the issue and the fact that only one dating of photoluminescence has been reported from the deepest level of the site (basal gravel layer) emphasize the need for new, denser and more diversified studies.

Abstract New investigations on Ustica (Palermo, Sicily) originated from the need to improve our knowledge of the island’s archaeological and environmental heritage. Through field surveys, particular attention was paid to human occupation in the Neolithic phases and focused on the less investigated southern side of the island. The systematic survey of the area of Piano dei Cardoni in 2018 brought to light a new Middle/Late Neolithic site, already partially documented in the literature. The island was settled for the first time during these phases, as also testified from the area of Punta Spalmatore. The presence of Serra d’Alto, incised dark burnished, and Diana styles suggests that the site and the archaeological assemblage dates from the mid to late 5th millennium BC, as confirmed by AMS dating. In addition to pottery, obsidian artifacts were also recovered, and a preliminary study of these materials is presented here. Portable XRF analyses on a sample of 41 obsidian artifacts, representing a high percentage of the lithic assemblage compared to chert tools, show that the provenance of the raw material is Gabellotto Gorge (Lipari) and Balata dei Turchi (Pantelleria). These results provide new insight into broader regional debates about obsidian technology and its exchange during the Neolithic and open an important consideration for sites that are far from the raw material sources.

Due to the construction of the M86 motorway, intensive quarrying activity started at several locations of the Rába Valley in Northwestern Hungary. This undertaking provided the discovery of a new archaeological site near the village of Páli in August 2014. During the rescue excavation, a rich lithic assemblage was unearthed, suggesting a human occupation related to the Epipalaeolithic–Early Mesolithic period. It is the first in situ site preceding the Neolithic in the region.

Muitos casos de declínio ou desaparecimento de espécies estão sendo documentados em todo o mundo, principalmente relacionados à modificação e perda de habitat. Nós apresentamos fortes evidências do desaparecimento de Proceratophrys moratoi nas áreas de ocorrência conhecida em sua localidade tipo: Botucatu, São Paulo, sudeste do Brasil. Entre agosto de 2006 e dezembro de 2008 nós fizemos amostragens exaustivas na busca pela espécie, nas duas áreas de ocorrência da espécie em Botucatu. No entanto, a espécie não foi registrada nessas áreas. A espécie possui alta especificidade e baixa plasticidade na ocupação do ambiente, não se adaptando as mudanças antrópicas em seu habitat. Estes dados demonstram a importância da conservação das áreas de ocorrência da espécie, principalmente na forma de reserva de proteção integral para garantir a sobrevivência das populações de Proceratophrys moratoi.

Os pellets surgem como uma opção interessante para a produção de biomassa e o bagaço de cana-de-açúcar, também, pode ser aproveitado na forma de pellets. Pellets é o nome dado ao produto resultante do processo de compressão aplicada a uma matéria prima, sendo que em muitos casos essa matéria prima é preparada previamente através do processo de secagem e moagem. O objetivo da pesquisa foi realizar a análise das propriedades: físicas - densidade, umidade, granulometria, diâmetro e comprimento, químicas – teor de carbono fixo, material volátil e cinzas, mecânicas -  durabilidade mecânica e o poder calorífico superior. Foram analisadas amostras de pellets provenientes de fazendas do Estado de São Paulo. As análises foram conduzidas no Laboratório Agroflorestal de Biomassa e Bioenergia (LABB/IPBEN) pertencente à Faculdade de Ciências Agronômicas (FCA/UNESP), sendo esta biomassa uma fonte alternativa de energia com alto teor energético e baixa umidade   Palavras-chave: poder calorífico superior, biomassa, fontes alternativas de energia.   PHYSICAL, CHEMICAL AND MECHANICAL CHARACTERIZATION OF SUGARCANE BAGASSE PELLETS   ABSTRACT: Bioenergy is one of the alternatives to reduce the dependence on fossil fuels in the world energy matrix. Pellets appear like an attractive option for the production of biomass, and sugarcane can be used in the form of pellets. Pellets are the name given to the product that affects the process of applying a raw material, and in many cases, this material is prepared for the drying and grinding process. The objective of the research was to carry out an analysis of the properties: physical - density, granulometry, diameter and length, chemical - fixed carbon content, volatile matter and ashes, mechanics - mechanical use, and higher heating value. Samples of pellets from farms in the State of São Paulo were analyzed. Analyzes were conducted at the Agroforestry Laboratory of Biomass and Bioenergy (LABB / IPBEN) belonging to the Faculty of Agronomic Sciences (FCA / UNESP), and this biomass showed to be an alternative source of energy with high energy content and low moisture.    Keywords:  higher heating value, biomass, alternative energy source.

This paper presents a geomorphological, pedological and geochronological characterization and contextualization of geomorphogenetic, chronomorphological and environmental sequences from the Araraquara area (central São Paulo State, Southeast Brazil), and their relationship to lithic material from hunter-gatherer archaeological lithic sites. A special emphasis is given to a detailed study of the lowlands of the Jacaré-Guaçu River (between the cities of Araraquara and Boa Esperança do Sul, São Paulo state, Brazil), near the Boa Esperança II hunter-gatherer archaeological site, BES II, in an area of clear asymmetry of the alluvial plain and adjacent slopes. Data derived from the survey of estimated morphogenetic and environmental dynamics are used to contextualize the archaeological material of the BES II site, which is discussed as being associated with the Pleistocene-Holocene transition (an unusual occupation age for the Brazil southeast). We pointed to alternation between successions linked to a quaternary manifestation of a longer pattern of changes of lateral flatting processes and stability of base level with others linked to vertical incision and adequacy to a new base level. We propose a geomorphological model for the Lowlands of Jacaré-Guaçu River, highlighting the possibility that the asymmetry of the plain would be linked to a wider heterogeneity of its geomorphological context of semidetails, partially correlated with the overlapping of neotectonic influence and environmental fluctuations. It is suggested that data from the physical environment of the above mentioned lowlands are compatible with absolute ages obtained by OSL (lower terrace Ia, 14,500±3000 years BP, basal gravel level of the surface coverings, to 10,900±1500 and 4090±340 years BP at the sandy soils and sediments above the gravel) and 14C (8630 years BP, at the level of gleyed sandy-clay soil of 120 cm deep of the low terraces IIa) on archaeological levels of the low terraces of the Jacaré-Guaçu river, in a context of climatic transition from semi-arid conditions to higher humidity, hydrological changes (ephemeral and torrential channels changing to oscillating regimes of perennial channels, with sets of meanders of variable widths of paleochannels, suggesting climatic changes related to the modifications of the fluvial patterns), successive fluctuations (< 10 m) of base levels and large (500 m) lateral migration of the main river to the north guiding the local chronomorphological successions between Late Pleistocene and Late Holocene. The landscape and fluvial dynamics changes over time has influenced the availability of attributes needed for the hunter-gatherer lifestyle (such as fluctuations in the deposition/exposure of river pebbles used as raw material for tool making). Those oscillations are presented as a contribution to explain alternation between more and less dense archaeological levels along the vertical cuts of the low terraces and the location of exception of the BES II site (installed on a fluvial plain and low terraces in a segment characterized by the rarity of rocky outcrops, while most sites in the Araraquara area are linked to slopes, proximal to rocky outcrops - primary sources of lithics artifacts making) on the geomorphological Araraquara area context
