"Interns and Volunteers Crucial in Curating and Digitizing Fossil Invertebrates in the Field Museum’s Fast Growing Mazon Creek Collection." Biodiversity Information Science and Standards 2 (June 13, 2018): e25942. http://dx.doi.org/10.3897/biss.2.25942.
Full textAbstract:
The Mazon Creek region in Northeastern Illinois is home to a Middle Pennsylvanian (~307 million years old) soft-bodied fossil Lagerstätte of animals and plants that lived along a subtropical swampy coastline. This area was strip mined for coal from 1928 to 1974 and museum geologists and amateur collectors acquired large fossil collections during this time by collecting and splitting millions of nodules unearthed at the mines. These large collections are important because of the rarity of many of the species in the Mazon Creek biota. There are about 250 described fossil invertebrate species from the Mazon Creek region. Fifty-one of these species (mostly insects and arachnids) are represented by just a single specimen in the Field Museum’s collection. Since the 1980’s collecting has decreased and the mines have been restored to parks and wildlife areas. The Field Museum maintained a collection of 34,000 Mazon Creek invertebrate fossil for many decades. With the new donations from private collectors in the last three years this collection has grown by 20% and now represents 18% of the Fossil Invertebrate systematic collection. The Mazon Creek is also the most used fossil invertebrate collection accounting for about 38% of loans in the last five years. Dealing with these large and often unexpected donations adds to the already large workload of the collection staff, so interns and volunteers are utilized to process, catalog, digitize, and integrate these fossils into the museum’s collection. In the summer of 2016, interns Mackenzie Best and Yaal Dryer unpacked and sorted into drawers the Thomas V. Testa collection, and digitized the first 1,000 fossils. In 2017, two Women in Science interns, Kate Hodge and Dana Kahn, spent 6 weeks entering the data for 5,000 fossils into our database, numbering these fossils, and printing their labels. Having a well curated collection, as well as volunteer Jack Wittry, who has expert knowledge of Mazon Creek fossils, has also been crucial to the success of these projects. Mane Pritza, a Field Museum volunteer, began photographing these collections and has captured over 11,000 images. Janel Nelson, a former volunteer, has uploaded these images into our multimedia database and linked them to the corresponding records in the catalog module. James and Sylvia Konecny donated their 4,000-specimen Mazon Creek collection in December of 2017, ensuring that interns and volunteers will continue their curation work for at least the next two years.

On October 6, 1846, M. W. Dickeson, a physician from Natchez, Mississippi, exhibited a collection of specimens of mastodon and sloth fossil bones that he had found in 1845 at the base of a bayou cut through the loess above the Mississippi River near his home. He had brought them to the Academy of Natural Sciences of Philadelphia to which he donated them. Among the specimens was a fragment of human pelvis, implicitly also fossil, from a deposit of blue clay 61 cm below the animal fossils, which included mylodon (now Glossotherium harlani) and Megalonyx jeffersoni. After 144 years of controversy over the antiquity of “Natchez Man,” a sample of the pelvis has been dated by accelerator mass spectrometry to 5580 ± 80 B.P.

Full textAbstract:
Home heating and lighting markets have played crucial and underappreciated roles in driving energy transitions. When historians have studied the adoption of fossil fuels, they have often privileged industrial actors, markets, and technologies. My analysis of the factors that stimulated the adoption of anthracite coal and petroleum during the nineteenth century reveals that homes shaped how, when, and why Americans began to use fossil fuel energy. Moreover, a brief survey of other fossil fuel transitions shows that heating and lighting markets have been critical drivers in other times and places. Reassessing the historical patterns of energy transitions offers a revised understanding of the past for historians and suggests a new set of options for policymakers seeking to encourage the use of renewable energy in the future.

Full textAbstract:
Between January and June 1904, Handel T. Martin (1862-1931), University of Kansas (KU), collected fossil vertebrates from the Early Miocene Santa Cruz Formation along the Río Gallegos and the Atlantic Coast of Patagonia, as Martin’s private initiative. In the account of the expedition, Martin stated that when he and his companion, arrived in Buenos Aires, they visited Florentino Ameghino at the Museo Nacional. His album of photographs shows that he also visited the Museo de La Plata and Ameghino’s home in La Plata. Before heading to Patagonia, Martin assembled his equipment in Bahía Blanca, where his brother had settled. It is not clear if Martin collected a total of 235 or 395 specimens. Clearly, his main goal was to collect fossils to sell, as many specimens were later sold to different institutions in the United States and Europe by Martin by himself and through Robert Ferris Damon, a well-known fossil and mineral trader of the time. To date, we have identified only about 170 specimens in formal collections. A large part of the collection – at least 130 of the choicest specimens – remained at KU, which constitutes one of the largest collections of santacrucian vertebrates outside Argentina (in addition to the ones in the Yale Peabody Museum in New Haven, the Field Museum in Chicago, and the American Museum in New York). Although the collection at KU is largely neglected by paleontologists and has seldom been studied, it contains a good representation of the Santacrucian fauna, with many fine specimens.

Full textAbstract:
The scientific community is in great need of input from paleontologists today in two key areas of societal concern: the historical basis of global change and losses of biodiversity. Paleontologists, with their unique perspective on rates of change in biotic communities and their training in filtering signal from noise in the fossil record, are the best placed scientists in biology to approach these problems from an historical viewpoint. In the classroom we give lip service to the central role of paleontology in understanding these problems. Yet with the exclusion of Quaternary (and particularly Recent) paleoecology from the mainstream of our field, we have abrogated this responsibility to other disciplines. Paleontologists are in danger of losing the opportunity to provide guidance on the very issues in paleontology where political interest and funding will lie in the not too distant future. As opportunities for employment of paleontologists in the petroleum industry fade, it is critical that academic paleontologists define new directions for graduate education in our field.The paleontological community needs to reincorporate Quaternary paleoecology into its mainstream, emphasizing the importance of a paleobiological perspective in environmental problem solving. As the developers of theory and methodology in the interpretation of the fossil record it is our responsibility to set the agenda as to how paleobiology should be utilized. Our professional societies should provide leadership as advocates for funding research and training in the new areas of applied paleobiology, lest paleobiology (as we define it) be marginalized and traditional paleontology programs be viewed by their home institutions as increasingly irrelevant. Employment opportunities in biostratigraphy are a thing of the past; applied paleontology must redefine itself for career opportunities at the top of the column, in such areas as recent climate change or the fossil record of human-induced ecological disturbances. The PIRLA Project (Paleoecological Investigation of Recent Lake Acidification) provides an excellent example of applying paleobiology to such problems, using the Recent diatoms, crustaceans, insects and pollen fossils to understand the chronology of the acid rain problem in eastern North America.Academic departments bear a responsibility to bring the important new applications of paleobiology into the classroom, demonstrating its societal relevance and training students to avail themselves of potential opportunities for paleobiologists in global change and biodiversity research. Recent developments in taphonomy or stratigraphic ordering of fossils could be extremely powerful tools if applied to environmental change problem solving. We need to make our students marketable by spending more time in the classroom teaching them about Recent diatom paleoecology and less on brachiopod biostratigraphy. Otherwise paleobiology may go the way of Egyptology.

"Trophic interactions between larger crocodylians and giant tortoises on Aldabra Atoll, Western Indian Ocean, during the Late Pleistocene." Royal Society Open Science 5, no. 1 (January 2018): 171800. http://dx.doi.org/10.1098/rsos.171800.
Full textAbstract:
Today, the UNESCO World Heritage Site of Aldabra Atoll is home to about 100 000 giant tortoises, Aldabrachelys gigantea , whose fossil record goes back to the Late Pleistocene. New Late Pleistocene fossils (age ca . 90–125 000 years) from the atoll revealed some appendicular bones and numerous shell fragments of giant tortoises and cranial and postcranial elements of crocodylians. Several tortoise bones show circular holes, pits and scratch marks that are interpreted as bite marks of crocodylians. The presence of a Late Pleistocene crocodylian species, Aldabrachampsus dilophus , has been known for some time, but the recently found crocodylian remains presented herein are distinctly larger than those previously described. This indicates the presence of at least some larger crocodylians, either of the same or of a different species, on the atoll. These larger crocodylians, likely the apex predators in the Aldabra ecosystem at the time, were well capable of inflicting damage on even very large giant tortoises. We thus propose an extinct predator–prey interaction between crocodylians and giant tortoises during the Late Pleistocene, when both groups were living sympatrically on Aldabra, and we discuss scenarios for the crocodylians directly attacking the tortoises or scavenging on recently deceased animals.

Full textAbstract:
Giant is a sprawling narrative, centered around the Benedict family, Texas cattle ranchers, and Jett Rink, a nouveau riche oilman. Originally serialized in Ladies' Home Journal in 1952, subsequently published as a novel, then adapted into George Stevens's 1956 film starring James Dean, Rock Hudson, and Elizabeth Taylor, Giant is a text that dramatizes the domestication and naturalization of the oil industry in the postwar United States while endorsing a multiracial vision of Texas. This essay explores how Giant ultimately arrives at nationalistic pluralism after representing the radical changes brought about by the modern oil industry in the US, particularly the erosion of traditional class divisions as Jett Rink's oil wealth exceeds the Benedict's ranching wealth. The subsumption of oil into liberal pluralism marks what this essay names “fossil-fuel futurity,” an ideological configuration in which normative life is produced through the commodities and modes of transportation made available by fossil-fuel culture. The essay then puts Giant into a broader context of narratives about oil in the postwar US, especially the television series Dallas (1978–91) and the film There Will Be Blood (2007). In all three texts, oil culture becomes postwar US culture, saturating aesthetic, affective, and family relations. The challenge for us, then, is to imagine a mode of futurity that does not replicate the ideological valences of “fossil-fuel futurity.”

Full textAbstract:
The faunal changes that occurred in the few million years before the Cretaceous–Palaeogene extinction are of much interest to vertebrate palaeontologists. Western North America preserves arguably the best fossil record from this time, whereas terrestrial vertebrate fossils from the eastern portion of the continent are usually limited to isolated, eroded postcranial remains. Examination of fragmentary specimens from the American east, which was isolated for the majority of the Cretaceous as the landmass Appalachia, is nonetheless important for better understanding dinosaur diversity at the end of the Mesozoic. Here, I report on two theropod teeth from the Mount Laurel Formation, a lower-middle Maastrichtian unit from northeastern North America. One of these preserves in detail the structure of the outer enamel and resembles the dentition of the tyrannosauroid Dryptosaurus aquilunguis among latest Cretaceous forms in being heavily mediolaterally compressed and showing many moderately developed enamel crenulations. Along with previously reported tyrannosauroid material from the Mt Laurel and overlying Cretaceous units, this fossil supports the presence of non-tyrannosaurid tyrannosauroids in the Campanian–Maastrichtian of eastern North America and provides evidence for the hypothesis that the area was still home to relictual vertebrates through the end of the Mesozoic. The other tooth is assignable to a dromaeosaurid and represents both the youngest occurrence of a non-avian maniraptoran in eastern North America and the first from the Maastrichtian reported east of the Mississippi. This tooth, which belonged to a 3–4 m dromaeosaurid based on size comparisons with the teeth of taxa for which skeletons are known, increases the diversity of the Maastrichtian dinosaur fauna of Appalachia. Along with previously reported dromaeosaurid teeth, the Mt Laurel specimen supports the presence of mid-sized to large dromaeosaurids in eastern North America throughout the Cretaceous.

Full textAbstract:
In Sub-Saharan Africa, there are active debates about whether increases in energy access should be driven by investments in electric grid infrastructure or small-scale “home solar” systems (e.g., solar lanterns and solar home systems). We summarize the results of a household electrical appliance survey and describe how households in rural Kenya differ in terms of appliance ownership and aspirations. Our data suggest that home solar is not a substitute for grid power. Furthermore, the environmental advantages of home solar are likely to be relatively small in countries like Kenya, where grid power is primarily derived from non-fossil fuel sources.

Full textAbstract:
In recent years, several factors such as environmental pollution which is caused by fossil fuels and various diseases caused by them from one hand and concerns about the dwindling fossil fuels and price fluctuation of the products and resulting effects of these fluctuations in the economy from other hand has led most countries to seek alternative energy sources for fossil fuel supplies. Such a way that in 2006, about 18% of the consumed energy of the world is obtained through renewable energies. Iran is among the countries that are geographically located in hot and dry areas and has the most sun exposure in different months of the year. Except in the coasts of Caspian Sea, the percentage of sunny days throughout the year is between 63 to 98 percent in Iran. On the other hand, there are dispersed and remote areas and loads far from national grid which is impossible to provide electrical energy for them through transmission from national grid, therefore, for such cases the renewable energy technologies could be used to solve the problem and provide the energy. In this paper, technical and economic feasibility for the use of renewable energies for independent systems of the grid for a dispersed load in the area on the outskirts of Isfahan (Sepahan) with the maximum energy consumption of 3Kwh in a day is studied and presented. In addition, the HOMER simulation software is used as the optimization tool.

GNS Science is home to New Zealand’s national rock, mineral and fossil collections. The National Petrology Reference Collection (NPRC) is a ‘nationally significant’ collection of rocks and minerals from on- and off-shore New Zealand, Antarctica and the rest of the world. The National Paleontological Collection (NPC) is another nationally significant collection; of fossil material from New Zealand, the South West Pacific region and Antarctica, with some overseas additions. Their status as nationally significant collections mean that GNS Science is contracted by the New Zealand Government to provide long-term collection management. Collectively, the NPC and NPRC constitute more than 200,000 samples, dating from the earliest days of New Zealand geology exploration in the late 1800s. The collections continue to grow by hundreds to thousands of samples per year, and are loaned nationally and internationally for scientific research. They are by far the largest collections of fossils, rocks and minerals housed in New Zealand, and are important earth science archives for the entire Zealandian Southern Ocean region. The collections are housed on-site at GNS Science in Lower Hutt, a few hundred meters from the surface trace of the Wellington Fault and within striking distance of other active faults that could generate major earthquakes. Best estimates suggest that the Wellington Region has an average return time of about 150 years for very strong or extreme ground shaking. Such proximity to this significant, active hazard means that steps must be taken to ensure the long-term security and integrity of the collections in the event of earthquake shaking, as well as other natural and non-natural disasters. To that end, the collection managers have written and implemented disaster mitigation, preparedness and recovery plans for the National Petrology Reference Collection and National Paleontological Collection. Here we define the earthquake hazard posed by the Wellington Fault, assess the risk to the collections, and present steps taken to manage that risk.

By transforming patterns of travel and work around the world, the COVID-19 pandemic is accelerating the transition to renewable energy and the decline of fossil fuels. Lockdowns brought car commuting and plane travel to a near halt, and the mass experiment in which white-collar employees have been working from home may permanently reduce energy consumption for business travel. Renewable energy and electric vehicles were already gaining market share before the pandemic. Under pressure from investors, major energy companies have started writing off fossil fuel reserves as stranded assets that are no longer worth the cost of extracting. These shifts may indicate that “peak oil demand” has arrived earlier than expected.

The Climate Change crisis is worsening daily. We must start to-day and not to-morrow limiting CO2 emission globally. The Antarctic is melting with alarming speed and causing sea water levels to rise by 24 inches in the Southern Hemisphere. Central Australia is experiencing its worst ever drought and forest fires causing immense damage; on 55 days in 2019 temperatures rose to 48°C while the ground temperature reached 62 °C. Vast tracts of land have been burned with loss of life, homes, produce and wildlife. Yet government reaction was skeptical of the Climate Change connection. At the same time Europe and England have had extreme rainfall and serious extensive flooding. Nowadays many countries have started to take Climate Change extremely seriously and put together plans to reduce or stop the use of coal and other fossil fuels. Most countries have pledged to stop using fossil fuels by 2030. The transport industry accounts for the major part of air pollution through the use of motor vehicles, ships and air transport. In this paper it is demonstrated that motor car usage contributes more than 3500 million metric tons of CO2 each year. UK in November 2020 pledged to combat Climate Change and reduce the emission of CO2 by 50% by 2030. Recently it has announced a ten- point drive to eliminate fossil fuels in transport, agriculture, industry and homes by 2035.Ajman should follow suit and use UK as an example. This paper will summarize the progress of renewable energy globally with examples. Renewable Energy is now a major source of generating electricity worldwide. It is clean, abundant and low cost.

Energy in developing countries essential for economic growth and development. In result of the rapid growth of development, society demands more electricity. In addition to that, unsustainable energy production can have a harmful effect on our environment. Solar energy is the most inexhaustible method of energy. With that has been stated, it is evident that PV technology is starting to be one of the primary roots of energy generator to supply power for development. The economic ambition is to create solar energy more cost effective and efficient, nevertheless, it is still not compatible with fossil fuel. Typically, in order for solar energy to replace the fossil fuel or at least support the development demands of energy, the implementation of solar energy system must increase in homes and plantation projects. This problem drove governments to come up with policies that encourage implementing solar system in homes of citizens. The most used policies are fed in tariff and net energy metering, which is applied in 80 nations round the globe. This paper studied the policies applied in solar energy in Malaysia in the past 8 years. The paper went over each policy and considered their financial and environmental welfare. It did show the effect of the policy applied at the time on the capacity installed in Malaysia.

AbstractDespite some sound basic assumptions, Wilkins & Wakefield portray a Homo habilis too linguistically sophisticated to fit in with the subsequent fossil record and thereby lose a reasoned explanation for human innovativeness. They err, too, in accepting a single-level model of conceptual structure and in deriving initial linguistic units from calls, a process far more dubious than the derivation of home-sign from naive gesture.

In our modern societies, One of the main and simplest signature traits is hot water as a convenient and efficient way of life either for industrial and domestic purposes, however, obtaining hot water in most cases will be through fossil fuel either by direct burning for the fuel for heating or indirectly by using electricity that generated by fossil fuel. Using solar heaters will limit the in some extent the usage of fossil fuel.
A flat solar water heater of (165 to 175) cm3 has been constructed to be used as a model for educational purposes. The solar heater is made of local materials consist of galvanized iron pipes, glass surfaces, wool insulation, aluminum frame, and fixed iron base. Moreover, Thermocouples, pyranometer, and an anemometer were used to test the performance of the heater in four days in May for the angle of inclination of the complex 320 is on the horizontal. In conclusion, the daily average efficiency was around 57%. The temperature in the tank is about 62 0C at noon, which is sufficient for home use throughout the day.

The combustion of fossil fuels is a significant source of particulate-bound black carbon (BC) in urban environments. The personal exposure (PE) of urban dwellers to BC and subsequent health impacts remain poorly understood due to a lack of observational data. In this study, we assessed and quantified the levels of PE to BC under two exposure scenarios (home-based and mobility-based exposure) in the city of Trivandrum in India. In the home-based scenario, the PE to BC was assessed in a naturally ventilated building over 24 h each day during the study period while in the mobility-based scenario, the PE to BC was monitored across diverse microenvironments (MEs) during the day using the same study protocol for consistency. Elevated BC concentrations were observed during the transport by motorcycle (26.23 ± 2.33 µg/m3) and car (17.49 ± 2.37 µg/m3). The BC concentrations observed in the MEs decreased in the following order: 16.58 ± 1.38 µg/m3 (temple), 13.78 ± 2.07 µg/m3 (restaurant), 11.44 ± 1.37 µg/m3 (bus stop), and 8.27 ± 1.88 µg/m3 (home); the standard deviations represent the temporal and spatial variations of BC concentrations. Overall, a relatively larger inhaled dose of BC in the range of 148.98–163.87 µg/day was observed for the mobility-based scenario compared to the home-based one (118.10–137.03 µg/day). This work highlights the importance of reducing PE to fossil fuel-related particulate emissions in cities for which BC is a good indicator. The study outcome could be used to formulate effective strategies to improve the urban air quality as well as public health.

Full textAbstract:
The Northeast Asian Region is a home for the major world’s energy importers and Russia – the top energy exporter. Due to the depletion of national fossil energy resources, the industrialised East Asian economies are facing serious energy security issues. The snapshot of the intraregional energy trade in 2019 was analysed in terms of development potential. Japan, Korea and China are at the frontline of hydrogen energy technologies commercialisation and hydrogen energy infrastructure development. The drivers for such endeavours are listed and national institutions for hydrogen energy development are characterised. The priorities related to regional cooperation on hydrogen energy in Northeast Asia were derived on the basis of hydrogen production cost estimations. These priorities include steady development of international natural gas and power infrastructure. The shared process will lead to the synergy of regional fossil and renewable resources within combined power and hydrogen infrastructure.

The high stakes of emergent environmental crises, from climate change to widespread toxic exposures, have motivated STS practitioners to innovate methodologically, including leveraging STS scholarship to actively remake environmental scientific practice and technologies. This thematic collection brings together current research that transforms how communities and academics identify, study, and collectively respond to contaminants engendered by the fossil fuel and petrochemical industries, including air contamination from hydraulic fracking, marine pollution from petroleum-derived plastics, and hydrocarbon derivatives such as formaldehyde that intoxicate our homes. These interventions make inroads into the “undone science” and “regimes of imperceptibility” of environmental health crises. Authors, most of whom are practitioners, investigate grassroots methods for collaboratively designing and developing low-cost monitoring tools, crowdsourcing data analysis, and imagining ways of redressing toxicity outside of the idioms of science. Collectively, these articles work towards remaking how knowledge is made about and across industrial systems by networking community grounded approaches for accounting for environmental health issues created by the fossil fuels and allied petrochemical industries.

Full textAbstract:
Today, global energy consumption is dominated by fossil fuels such as oil, coal and gas. The intensive consumption of these energy sources gives rise to greenhouse gas emissions and therefore an increase in CO2 emissions. Photovoltaic energy has persistently been considered as a green and pollution-free renewable energy source to overcome greenhouse effect and energy crisis. This paper describes a new method of photovoltaic energy sharing in standalone micro-grids using photovoltaic panels. This approach is based on automatic electrical energy sharing depending on the state of charge (SOC) of the electrical storage unit using by each home and on the electrical power consumption of each home.The monitoring system is connected to each home in micro-grid, it manage each home’s energy use, and assigns more energy to a large energy-consuming home. This architecture contributes to reducing total energy lost.

Currently, most of the vehicles make use of fossil fuels for operations, resulting in one of the largest sources of carbon dioxide emissions. The need to cut our dependency on these fossil fuels has led to an increased use of renewable energy sources (RESs) for mobility purposes. A technical and economic analysis of a one-stop charging station for battery electric vehicles (BEV) and fuel cell electric vehicles (FCEV) is investigated in this paper. The hybrid optimization model for electric renewables (HOMER) software and the heavy-duty refueling station analysis model (HDRSAM) are used to conduct the case study for a one-stop charging station at Technical University of Denmark (DTU)-Risø campus. Using HOMER, a total of 42 charging station scenarios are analyzed by considering two systems (a grid-connected system and an off-grid connected system). For each system three different charging station designs (design A-hydrogen load; design B-an electrical load, and design C-an integrated system consisting of both hydrogen and electrical load) are set up for analysis. Furthermore, seven potential wind turbines with different capacity are selected from HOMER database for each system. Using HDRSAM, a total 18 scenarios are analyzed with variation in hydrogen delivery option, production volume, hydrogen dispensing option and hydrogen dispensing option. The optimal solution from HOMER for a lifespan of twenty-five years is integrated into design C with the grid-connected system whose cost was $986,065. For HDRSAM, the optimal solution design consists of tube trailer as hydrogen delivery with cascade dispensing option at 350 bar together with high production volume and the cost of the system was $452,148. The results from the two simulation tools are integrated and the overall cost of the one-stop charging station is achieved which was $2,833,465. The analysis demonstrated that the one-stop charging station with a grid connection is able to fulfil the charging demand cost-effectively and environmentally friendly for an integrated energy system with RESs in the investigated locations.

Electric vehicles (EVs) have a lot of potential to play an essential role in the smart power grid. EVs not only can reduce the amount of emission yielded from fossil fuels but also can be considered as an energy storage system (ES) and a backup system. EVs could support the demand response (DR) strategy that is considered as utmost importance to shift electricity demand in peak hours. This article aims to assess the impact of the presence of EV on DR strategy in a home-microgrid (H-MG). In order to reach the optimal set point, our energy management system (EMS) has been merged with differential evolution (DE) method. The results were auspicious and showed that the proposed method could decrease market clearing price (MCP) by 26% and increase the performance of DR by 17%.

Over the past few decades, there has been a recognition of the growing need for different forms of energy outside of fossil fuels. Since the latter half of the twentieth century individuals, corporations, and governments have become increasingly aware of the effects of the emissions of carbon and other harmful pollutants on the environment. With this greater concern has come increasing activity to combat these harmful emissions by using alternative fuel sources to power homes, businesses, and cities. As can be seen from recent trends in their installed capacity, it is clear that renewable energy resources will continue to be more commonly used in the future. As renewable energy increases, a decrease in a range of harmful pollutants from the energy sector will also occur. This paper provides a case study to estimate the potential environmental and health benefits of an increased shift from fossil fuels to renewable fuels for electrical production in Oklahoma. Results illustrate and quantify the specific reduction that wind energy can and will have on air quality, as well as provide a quantification of the associated potential health benefits.

AbstractSmall shelly fossils, especially conoidal microfossils, have potential for biostratigraphic correlation of Precambrian–Cambrian boundary rocks where evolutionary successions of taxa can be recognized. A succession of hyoliths, brachiopods and species of Sunnaginia, Torellella, Eccentrotheca and Rhombocorniculum can be recognized in the Home Farm Member of Nuneaton and/or the Comley Limestone of Shropshire, England. Revised ranges of taxa are given and Sunnaginia neoimbricata n.sp., S. parva n.sp., S. angulata n.sp., Eccentrotheca grandis n.sp. and several new records are described from Nuneaton and Comley. The similarity in the sequence of small shelly fossils in England and Siberia indicates that a correlation can be achieved between the two areas. It is suggested that the lower Tommotian to lower Atdabanian correlates with the Hartshill Formation of Nuneaton, of which the condensed Home Farm Member spans the mid Tommotian to lowest Atdabanian, while the upper Atdabanian to lower Botomian correlates with the condensed Comley Limestone of Shropshire.

The ‘Rühle collection’ is one of the largest remaining historical collections of Central European Triassic fossils and is now located at the Berlin Museum of Natural History (MfN). The collector, Hugo Rühle von Lilienstern, a medical doctor who lived in southern Thuringia, was a dedicated palaeontologist. From the 1950s his home and collection area were situated in a region that became the borderland between the two German States. The fate of the collection was thus closely interwoven with East-West German history after World War II. The scientific value of these mostly Middle to Late Triassic Central European fossils and its standing compared to other late Triassic palaeobotanical collections is evaluated.

Abstract. The Eurasian (née European) Modern Pollen Database (EMPD) was established in 2013 to provide a public database of high-quality modern pollen surface samples to help support studies of past climate, land cover, and land use using fossil pollen. The EMPD is part of, and complementary to, the European Pollen Database (EPD) which contains data on fossil pollen found in Late Quaternary sedimentary archives throughout the Eurasian region. The EPD is in turn part of the rapidly growing Neotoma database, which is now the primary home for global palaeoecological data. This paper describes version 2 of the EMPD in which the number of samples held in the database has been increased by 60 % from 4826 to 8134. Much of the improvement in data coverage has come from northern Asia, and the database has consequently been renamed the Eurasian Modern Pollen Database to reflect this geographical enlargement. The EMPD can be viewed online using a dedicated map-based viewer at https://empd2.github.io and downloaded in a variety of file formats at https://doi.pangaea.de/10.1594/PANGAEA.909130 (Chevalier et al., 2019).

The renewables energies are being used to reduce the environmental pollution, combat the climate change and burning of fossil fuels. For remote or decentralized areas, where grid connection is very complex, renewable energy generation system can be a reliable and optimized source of energy. Moreover, wind-diesel-solar hybrid system technology promises lots of opportunities in remote areas which are far from the main grid and are supplied by diesel gensets. This paper is based on the analysis of a hybrid energy system for optimization. The analysis of the hybrid system is realized in the HOMER software package. The HOMER software was utilized as the assessment tool with modeling performed with hourly data of wind speed, solar radiation and load. In this study, the remote village of Tuktoyaktuk situated in Northwest Territories of Canada has been taken for the discussion of the optimization analysis of a hybrid energy generation system.

Electricity has become a very important needs for human life today and one of the parameters in one region condition. Nowadays, the dependence on fossil fuels to fulfill the electricity needs is really worrying, and it causes the depletion of fossil fuels. Today, the whole world is paying more attention to renewable energy as one of the best solution to solve the future energy problems. Renewable energy becomes the best solution because it will not be exhausted and enviromentally friendly. In the other hand, renewable energy also have problem, because it cannot produce energy everytime like photovoltaics which can produce energy only when there is enough solar radiation. Therefore, a hybrid system is made that expected to minimize the weakness from other components of the system. In this project, a hyrid system is designed using HOMER PRO software to calculate the electricity and economic factor of the hybrid system. The objective of this project is to find the best hybrid system that can solve the electricity problems. The system will be independent since grid function will replaced by fuel cell in the 19th year based on the assumption.

Because of its importance, it is a site which everyone should know about. To give us a feeling for Lake Mungo, Billy Reid, the illustrator of The Aboriginal Health Worker and The Aboriginal Child at School, came with me on a trip. We travelled west to the Darling River (whose Aboriginal name is Calewatta), and then south-east to Lake Mungo itself. Billy made wonderful drawings to represent the deeds and everyday life of those people. This can be reconstructed from the fossil evidence found at Lake Mungo. He has also drawn some scenes of life along the banks of the Calewatta - the river which is Billy’s own home. He hails from Bourke.

Full textAbstract:
Socioeconomic development in low- and middle-income countries has been accompanied by increased emissions of air pollutants, such as nitrogen oxides [NOx: nitrogen dioxide (NO2) + nitric oxide (NO)], which affect human health. In sub-Saharan Africa, fossil fuel combustion has nearly doubled since 2000. At the same time, landscape biomass burning—another important NOx source—has declined in north equatorial Africa, attributed to changes in climate and anthropogenic fire management. Here, we use satellite observations of tropospheric NO2 vertical column densities (VCDs) and burned area to identify NO2 trends and drivers over Africa. Across the northern ecosystems where biomass burning occurs—home to hundreds of millions of people—mean annual tropospheric NO2 VCDs decreased by 4.5% from 2005 through 2017 during the dry season of November through February. Reductions in burned area explained the majority of variation in NO2 VCDs, though changes in fossil fuel emissions also explained some variation. Over Africa’s biomass burning regions, raising mean GDP density (USD⋅km−2) above its lowest levels is associated with lower NO2 VCDs during the dry season, suggesting that economic development mitigates net NO2 emissions during these highly polluted months. In contrast to the traditional notion that socioeconomic development increases air pollutant concentrations in low- and middle-income nations, our results suggest that countries in Africa’s northern biomass-burning region are following a different pathway during the fire season, resulting in potential air quality benefits. However, these benefits may be lost with increasing fossil fuel use and are absent during the rainy season.

After over a century with utilization of the benefits of economics of scale, power systems planning and development gets bigger and transmission grids have needed to transmit wide bringing the concept of onsite or close-to-load generation back. The turnaround strategy is prompted by market liberalization, transmission expansion constraints, related technology advancements, environmental pollution, health hazards, fossil fuel depletion, and climate change concerns. In the last decade, many countries have started the process of liberalisation of the electric systems, opening access to transmission and distribution grids.Technical feasibility analysis of a hybrid energy system for two types of geographical regions in South Africa using Homer is performed in this paper.

Introduction: Electric Vehicles (EV) are fast emerging globally as a viable alternative to traditional fossil fuel burning cars and are now being presented as a resolution for the problem of dependence of fossil fuels, increasing emissions, and other environmental issues. Purpose and Objective: The study explores the neighborhood knowledge toward green mobility and the objective of this paper is to investigate and examine neighborhood perceptions and understand their knowledge towards the electric vehicle. The research paper goal necessitated the knowledge of the underserved community towards green mobility. Methods: Following the literature review research phase, the researcher conducted several semi structured interviews with underserved community. To best augment the quantitative, data were gathered from underserved Edmonton Height community, through the design of questionnaire survey. Data collection took place during the last two weeks of October 2018. Neighborhood households were approached during the day and evening in their residents using a structured questionnaire. Results: The analysis reveals that that 60% of the respondents not aware of plug-in EV incentives (such as tax credit, rebate, high occupancy lane access, reduced tolls, lower vehicle registration rates, or discounted electricity rates) offered by the federal government; their state government; local community; their electricity provider; their employer, while 10% indicated federal government and 10% local community and 5% indicated electric providers, 5% employers and 5% state government. However, the pilot results are a useful estimate of the number of households residents residing in Edmonton Heights don’t know that plug-in EVs can be recharged from a regular home outlet. Conclusion: The paper concludes that the progress that the electric vehicle industry has seen in recent years is not only extremely welcomed, but highly necessary considering the increasing global greenhouse gas levels and it should be noted that a range of technology options is being aggressively explored to facilitate the transition to a more sustainable transport system. Near term, technologies such as EVs can provide sustainable mobility and help alleviate some of the problems created by conventional vehicle powered by fossil fuels. Notwithstanding, the pilot results are a useful estimate of the number of households residents residing in Edmonton Heights don’t know that plug-in EVs can be recharged from a regular home outlet.

India is presently focusing on complete utilization of solar energy and saving fossil fuels, which are limited. Various solar energy systems like solar cookers, solar water heaters, solar lanterns, solar PV lights, and solar lamps are continuously availing by the people of India at a low cost and on good subsidies. Apart from this, India is a solar energy promising country with a good number of solar homes (carrying solar energy systems) in its various locations. The present paper focuses on a unique combination of solar dish cooker (SDC) and solar water heater (SWH) to produce distilled water with a high distillate and a high daily productivity. The procedure has been discussed on the basis of experimental testing to produce distilled water by combining an evacuated type SWH and a SDC. Experimentation has been carried out in MIT, Moradabad (longitude, 28.83°N, and latitude, 78.78°E) by developing the same experimental setup on behalf of solar homes. The daily productivity of distilled water was found around 3.66 litres per day in full sunshine hours for an approximated pH value of 7.7 and a ppm value of 21. The payback period (PBP) has been estimated around 1.16 years of the present system.

China, the world's largest market for electric vehicles (EV), has put in play a state industrial policy that is seeking to upend global automakers (see Financial Times, October 12, 2017 and May 20, 2018). Exemptions from taxes and subsidy programs have favored the purchasing of an EV, which are also exempt from driving restrictions in large cities such as Beijing and Shanghai. Policies that target manufacturers include meeting production targets for EVs (the so-called dual-credit policy by the Ministry of Industry and Information Technology). China may be on the verge of becoming a global disruptor in an industry that has home market advantages of scale, lower fossil fuel imports, and significant reduction of air pollution in cities while exploiting related technologies such as lithium batteries where China has world class industrial competence. It is in China's national interest to be a game changer in the global automotive industry from fossil fuel to electricity. And building infrastructure – supercharging stations included – fits the government-directed approach that aspires to establish the country as an undisputable global leader in a high-tech sector of global significance.

This work shows the design project of a photovoltaic system to power a home, based on a demand study and its general characteristics, the area available for the assembly was considered of the modules, the geographical location and the meteorological data of the place. With this information, the pertinent calculations were made to ensure that the installation provides the energy necessary to cover the consumption of the home and that it also delivers the surplus energy to the network. PVsyst software was used for the design of the photovoltaic system. To verify the advantages of the implementation of the photovoltaic arrangement, the benefit-cost ratio was evaluated, carrying out an environmental impact analysis taking into account the reduction of CO2 emissions into the atmosphere and the tons of fossil fuel stopped burning when generating electricity with This source of energy. It is convenient to install.

The governments world-wide are deliberating to promote renewable energy sources such as wind to mitigate increasing demand of energy and to overcome effects of pollution due to to use of fossil fuels. Integration of wind turbine generators (WTG) with the diesel plants is pursued widely to reduce dependence on fossil-fuels and to reduce carbon emissions. Literature indicates that commercial/residential buildings in the Kingdom of Saudi Arabia (K.S.A) consume an estimated 10 - 40% of the total electric energy generated. The aim of this study is to analyze wind-speed data of Dhahran (East-Coast, K.S.A.) to assess the economic feasibility of utilizing hybrid wind-diesel power systems to meet the load requirements of a typical commercial building (with annual electrical energy demand of 620,000 kWh). The monthly average wind speeds range from 3.3 to 5.6 m/s. The hybrid systems simulated consist of different combinations of 100 kW commercial WTG supplemented with diesel generators. NREL?s (HOMER Energy?s) HOMER software has been employed to perform the techno-economic analysis. The simulation results indicate that for a hybrid system comprising of 100 kW wind capacity together with 175 kW diesel system, the wind penetration (at 37 m hub-height, with 0% annual capacity shortage) is 25%. The cost of generating energy (COE, $/kWh) from this hybrid wind-diesel system has been found to be 0.121 $/kWh (assuming diesel fuel price of 0.1$/liter). The study exhibits that for a given hybrid configuration, the number of operational hours of diesel gensets decreases with increase in wind farm capacity. Emphasis has also been placed on wind penetration, un-met load, energy production and COE, excess electricity generation, percentage fuel savings and reduction in carbon emissions (relative to diesel-only situation) of different hybrid systems, cost break-down of wind-diesel systems, COE of different hybrid systems, etc.

Full textAbstract:
The transition from fossil generated energy towards regenerative energy sources is an important topic. Especially the generation from wind power plants and photovoltaic systems underlines the most important difference in comparison to conventional energy generation and distribution. One of the main characteristics of renewable energy sources is its decentralized generation, where existing distribution paths will become more and more a bottleneck in the future. The solution for this challenge is called smart grid and is driven by information, such as energy consumption, in order to match energy demand and supply. The SmartEco idea makes it possible to offload some of the energy’s surplus form the grid to individual customer homes in the context of the smart gird approach.

O presente artigo trata do papel do ser humano, enquanto imago dei e homem e mulher, na obra da creatio continua. Visa evidenciar que o casamento está fundamentado na própria criação e não se pode compreender tal instituição sem considerações protológicas. O próprio Senhor Jesus Cristo ressaltou a ligação do casamento com a obra divina de criar, no início, homem e mulher, com a finalidade que estes se associassem em profundo amor, pois foi intenção daquele que faz todas as coisas que homem e mulher fossem uma só carne. O trabalho também tenciona mostrar que o ser humano tem função no contexto da criação contínua e que, no fim, a humanidade só pode cumprir tal função no âmbito do casamento, onde se forma vínculo de amizade, amor e cuidado necessários para o fundamento da sociedade e cultura. Tentativa de cumprir o simples propósito de multiplicação numérica coloca o humano no mesmo nível da animalidade e apenas uma união em amor proporciona o ambiente propício para a constituição da nova vida e nova geração.
