A produção e o consumo de energia são ambientalmente impactantes, mas os padrões atuais de consumo podem ser melhorados, estimulando o uso mais eficiente de energia e transição de fontes de energia fósseis para fo...

Abstract Historically, great powers have gone to great lengths to guarantee the energy necessary to compete in the international system. Today, as fossil fuel sources diminish and energy demands increase, the most power...

Systematic tool use is a central component of the human niche. However, the timing and mode of its evolution remain poorly understood. A newly developed method for the analysis of muscle recruitment patterns (Validated E...

Se realizó el relevamiento de las sedimentitas de la Formación Montaña (Triásico) en el área de Santa Clara, en el norte de la provincia de Mendoza, Argentina. Durante el levantamiento de datos se determinó la exis...

The Middle Pleistocene hominin fossil record is taxonomically diverse, with Homo sapiens, Homo neanderthalesis, Homo naledi, and Homo erectus, all existing at various times during this period. These species are generally...

The Dinaledi Chamber of the Rising Star cave system has yielded a large assemblage of fossil hominin material, attributed to Homo naledi. The unusual taphonomic and geological situation of the assemblage suggested that t...

Geochemical and geochronological analyses of samples of surficial Acre Basin sediments and fossils indicate an extensive fluvial-lacustrine system, occupying this region, desiccated slowly during the last glacial cycle (...

Modern baleen whales (Mysticeti), the largest animals on Earth, arose from small ancestors around 36.4 million years ago (Ma). True gigantism is thought to have arisen late in mysticete history, with species exceeding 10...

Developmental plasticity, the ability to regulate aspects of development in response to environmental cues, is hypothesized to evolve in response to environmental heterogeneity and may facilitate dispersal, novel habitat...

Homo naledi is known from the Rising Star cave system, South Africa, where its remains have previously been reported from two localities: the Dinaledi Chamber (U.W. 101) and Lesedi Chamber (U.W. 102). Continued explorati...

Abstract As energy crisis and environment pollution all around the world threaten the widespread use of fossil fuels, compressed natural gas (CNG) vehicles are explored as an alternative to the conventional gasoline powe...

Algae biofuels is considered as an alternative source to fossil fuels. In recent ‎decades, there was a ‎significant increase in the use of energy sources in order ‎to avoid the depletion of traditional ‎sources s...

As the twentieth century neared its midpoint, paleoanthropology was in dire need of revitalization and some coherent concept of evolution.  Sadly, as introduced to paleoanthropology by Ernst Mayr in 1950, the Modern Evo...

Los Xenarthra (Mammalia) constituyen un grupo monofilético, caracterizado por una arquitectura esqueletaria particularmente distinta a la de los demás mamíferos placentarios. Su distribución actual es casi exclusivam...

Two biogeographical units are generally recognized in the present shelf area of Argentina: the Magellanian andArgentinian Provinces. The two provinces differ in their fossil record. The evolution of these provinces has b...

Los Metriorhynchidae fueron los únicos Crocodylomorpha con un estilo de vida marino pelágico. Relacionado con este estilo de vida, su peculiar plan corporal permite diferenciarlos claramente de los demás Crocodylomorp...

Abstract Background The residential building sector is a major contributor to Germany’s greenhouse gas emissions. Over 60 % of the energy used for space and domestic hot water heating comes from fossil fuels sources a...

Foram examinadas sete espécies de Euphorbiaceae s.l. que ocorrem no Estado de Santa Catarina, Brasil: Actinostemon concolor, Hieronima alchorneoides, Maprounea brasiliensis, Pachystroma longifolium, Pausandra morisiana,...

Abstract In modern fossil and nuclear power plants, the components are subjected to creep, fatigue, and creep-fatigue (CF) due to frequent start-up and shut-down operations at high temperatures. The CF interaction on the...

After teeth, mandibles and mandibular fragments are the best represented element in the early hominin fossil record. Among these, the mandibular hypodigm of Paranthropus boisei is the largest ascribed to a single early h...

The Microbiotheria constitutes a group of Australidelphian marsupials from South America. The biochron of the Microbiotheria extends from the early Paleocene to the present with a single living species (Dromiciops gliroi...

The fossil record of New World vultures (Cathartidae) and hawks (Accipitridae) in South America is extensive but still remains patchy, with relatively few records coming from northern South America. The aim of the presen...

Amid escalating global climate concerns, the reliance of the transportation sector on high-carbon fossil fuels urgently demands sustainable alternatives. Hydrogen has emerged as a potent solution because of its zero-emis...

Deciphering the taxonomic and evolutionary relationships among hominin fossils of the Chibanian (ca. 774–129 ka) is challenging. This difficulty stems from biological factors such as mosaic patterns of morphological ch...
