Reign Of The Beast - The Atheist World Of W. D. Saull And His Museum Of Evolution

de Adrian Desmond

~~6,99€~~ 5,59€ 20% IMEDIATO + 5% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 In the 1830s, decades before Darwin published the Origin of Species, a museum of evolution flourished in London. Reign of the Beast pieces together the extraordinary story of this lost working-man&#39;s institution and its enigmatic owner, the wine merchant W. D. Saull. A financial backer of the anti-clerical Richard Carlile, the ‘Devil&#39;s Chaplain’ Robert Taylor, and socialist Robert Owen, Saull outraged polite society by putting humanity’s ape ancestry on display. He weaponized his museum fossils and empowered artisans with a knowledge of deep geological time that undermined the Creationist base of the Anglican state. His geology museum, called the biggest in Britain, housed over 20,000 fossils, including famous dinosaurs. Saull was indicted for blasphemy and reviled during his lifetime. After his death in 1855, his museum was demolished and he was expunged from the collective memory. Now multi-award-winning author Adrian Desmond undertakes a thorough reading of Home Office spy reports and subversive street prints to re-establish Saull&#39;s pivotal place at the intersection of the history of geology, atheism, socialism, and working-class radicalism.

Natural Climate Changes - Facts Based On Geological, Archaeological And Astrophysical Aspects

de Stefan Uhlig

24,99€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 In times of the European Medieval, the powerful contemporaries and influencers propagated the geocentric model of the world according to which the Earth should have been located in the centre of the Universe and the Sun and the planets should have circumnavigated the Earth. A modern analogue is the current superstition that the human is provoking and can control the climate change by the anthropogenic emission of carbon dioxide. This book presents examples of continuous natural climate changes, such as the development of the temperature of Earth's atmosphere, the oceans' sea levels and the ice volumes of the last few millions of years. These are explained and discussed, presenting data from different scientific areas such as geosciences, archaeology and astrophysics. Hereby, we will see that quite complex astrophysical and heliophysical mechanisms cause the periodically recurring long- and short-term variation of climate which cannot be influenced at all by any human being, also not by any increased or reduced emission of anthropogenic carbon dioxide. Controlled by the Sun's energy reaching the Earth's surface, the oceans are the global player interacting with the atmosphere and dominating its temperature. It was intended to write this book in an understandable style for everybody interested to learn more about the controversially discussed topic of climate change, or who is affected by the drastic measures of policy and want to form their own opinion. On the other hand this publication wants also to be a compact base and reference for the scientific young generation to invite them to immerse themselves into this very interesting and exciting field of natural sciences.

Granite Landscapes Of The World

de Piotr Migon

241,14€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Outcrops of granitic rocks cover a large proportion of the Earth's surface and host a range of spectacular landforms and landscapes, from extensive plains dotted by inselbergs to deeply dissected mountain ranges. They are often strikingly beautiful, but more importantly, they provide valuable insights into the mechanisms of geomorphic evolution both in the past and at present. The book offers a comprehensive view of the geomorphology of granite areas, examining individual landforms and their assemblages. Weathering processes, and the phenomenon of deep weathering in particular, are given much emphasis as these are fundamental to the understanding of the geomorphic evolution of granite areas. Granite landforms directly related to weathering, such as boulders, tors, inselbergs, and features of surface microrelief are examined in respect to their characteristics and origin. Patterns of slope evolution are shown in the context of both rock slopes and deeply weathered terrains. Granite geomorphology in the coastal, periglacial and glacial context is presented to show how the characteristics of granite control landform evolution in these specific environments. In the closing part a variety of geological controls is reviewed and their primacy over other factors is advocated, followed by an attempt to provide a typology of natural granite landscapes. Finally, certain specific ways of human transformation of granite landscapes are presented. The book will be useful to a range of earth science disciplines, including geomorphology, igneous petrology, engineering geology and soil science. Cultural geographers and people dealing with conservation of geological heritage should find it of interest. Examples from all parts of the world and extensive referencing ensure that it will act as an up-to-date guidebook to the fascinating world of granite geomorphology.

DISPONIBILIDADE IMEDIATA

 Bachelor Thesis from the year 2019 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, , course: APPLIED GEOLOGY, language: English, abstract: The inhabitants of Abesan Area, Southwestern Nigeria depend on groundwater for their daily domestic consumption and irrigation purposes. Thirty groundwater samples were collected from selected shallow hand-dug wells hosted in the Coastal Plain Sands aquifer for groundwater quality assessment. The samples collected were analyzed for pH, Total Dissolved Solids (TDS), Electrical Conductivity (EC), and dissolved ions (Na+, K+, Ca2+, Mg2+, HCO3-, SO42-, Cl-, and NO3-) for water quality assessment as well as their suitability for irrigation. Results of chemical analyses of groundwater showed that the relative concentration of cations and anions are in the order of Ca2+>Mg2+>Na+>K+ and HCO3>Cl-->SO42-->NO3-, respectively. The plots in all the locations indicated that the bicarbonate ions dominate other anions while calcium ions dominate other cations. The predominance of bicarbonate ions suggests a continental origin for the groundwater of the study area. The chemical quality of the water samples is within the acceptable limit of the World Health Organization (WHO) standards for drinking, domestic, and irrigation purposes in all the wells studied. Five water irrigation quality parameters were employed for this study which include the Magnesium Adsorption Ratio (MAR), Sodium Absorption Ratio (SAR), Soluble Sodium Percentage (SSP), Residual Sodium Carbonates (RSC), and Kelly's Ratio. Based on the irrigation parameters calculated, all the samples were classified as suitable for agriculture purposes. Most of the sampled groundwater in the Abesan Area from this study is found suitable for domestic and irrigation purposes.

44,81€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Doctoral Thesis / Dissertation from the year 2017 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, University of Jos, language: English, abstract: Rocks of the basement complex form the parent materials for about half of the soils on the Jos Plateau, and some of these soils are intensively utilized for agricultural purposes on an annual basis. However, not much information is available on their formation and properties. The knowledge on their formation and properties is essential for their sustainable management and utilization. The objectives of this study were: to characterize soils over selected basement complex lithologies on the Jos Plateau, assess their pedogenic characteristics, classify the soils using standard guidelines, investigate the pedogenic processes responsible for their formation, and evaluate erosional processes influencing pedogenesis in the study area. These would ensure a proper understanding of their pedogenic characteristics, and also allow better soil management and sound land use planning. The research entailed a detailed field survey, which was preceded by initial detailed study of existing information and reconnaissance surveys of the study area. The study area was stratified into different geologic units, and within each unit further stratification was based on topographic characteristics. Surface soil sampling and profile pits studies were carried out; and morphological data collected using guidelines in the soil survey manual. Soil samples were analyzed in the laboratory using standard procedures and data collected was subjected to statistical analysis. Geographic Information Systems were used to analyze spatial data, while the Universal Soil Loss Equation was used to assess erosional processes in the study area. This study has shown that various soil types exist in the basement complex areas of the Jos Plateau. Areas with high to extremely high actual erosion rates cover about 77% of the basement complex derived arable soils, thereby influencing soil fertility and pedogenic processes.

DISPONIBILIDADE IMEDIATA

 Bachelor Thesis from the year 2022 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 4.06, University of Nigeria, course: Geology, language: English, abstract: The study covers the areas around Ihe, a town in Awgu southeastern Nigeria. It lies within the Anambra Basin and is underlain by the Nkporo Group and Mamu Formation. Geologic field mapping involved outcrop description and lithofacies analysis. Laboratory studies include sieve analysis, paleocurrent analysis and pebble morphometry. These studies were carried out in order to interpret the paleodepositional environment of the rocks mapped. The lithofacies mapped consist of six lithofacies which include; Cross bedded sandstone facies, Shale facies, Structureless (massive) sandstone facies, Parallel laminated sandstone facies, bioturbated sandstone facies, and Ironstone facies. These lithofacies represents three facies association; FA1 - marine deposits, FA2 - shoreface deposits and FA3 - mouth bar deposits. This implies that the sediments were deposited within the marginal marine, shallow marine and marine environment respectively. The results from sieve analysis indicates that the sandstones are medium - coarse grained and poorly moderately sorted. Derivations from multivariate and bivariate sieve results depicts a fluvial setting. The pebble morphometry result also implies a fluvial setting. The paleocurrent analysis showed a unimodal pattern with provenance in the NW, possibly the western and northcentral basement complex area. A mean vector azimuth of 79.6o and a variance of 758.635o signified low sinuosity fluvial setting and southeasterly paleoflow direction. The integration of the results gotten from the various analysis interprets the paleodepositional environment of Ihe and environs to be a fluvial dominated marginal marine environment.

DISPONIBILIDADE IMEDIATA

 Seminar paper from the year 2022 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 1,0, University of Hamburg (Erdsystemwissenschaften), language: English, abstract: This paper examines the impacts of climate change on irrigated agriculture in southern Pakistan. The Pakistani provinces of Sindh and Punjab are part of the Lower Indus Basin, where the Indus River is the main source of irrigation. Statements about the future development of wheat production are difficult because they are based on climate forecasts, which themselves exhibit a high degree of variance. Accordingly, relevant literature shows differences in statements about the influence of climate change on wheat production and usually focuses on the influence of temperature, precipitation and extreme weather, but does not consider the discharge of the Indus River. This paper reviews current research findings from various sources based on the factors of (1) temperature and precipitation, (2) extreme weather events, and (3) Indus runoff volume, and is the first paper to combine all three factors to make predictions about wheat production. Finally, an overview of possible adaptation strategies is provided.

DISPONIBILIDADE IMEDIATA

 Master's Thesis from the year 2005 in the subject Engineering - Geotechnology, Haramaya University (Faculty of Agriculture, Department of Agricultural Engineering), language: English, abstract: Water harvesting technologies are being promoted at the household level in Oromia Region. Among the different types of surface runoff water harvesting structures adopted in the region, earthen pond seems to be the major one practiced by many farmers. Huge numbers of earthen ponds have been implemented to date in different sites. However, the problem of seepage is not adequately addressed; loss of water from the ponds due to seepage and evaporation has been reducing the performance of the ponds. These days, polyethylene membrane has been provided by the government to solve the problem and this membrane has been found to reduce seepage loss by 90%. Unfortunately, the membrane is too costly and not easily available to all farmers. Therefore, to alleviate the situation, alternative methods of reducing seepage loss were investigated in this experiment. Biological and physical methods for reducing seepage were evaluated in small ponds constructed in permeable silty clay soils of the Region. The biological method involved use of bio-plastic sandwiches made up of successive layers of soil, manure, vegetative material and soil. The physical method involved compacting of existing soil and treating the surface by termite mold mix soil. The biological methods reduced the mean cumulative seepage rate by 47% and the physical treatment reduced by 21% after 90 days of wetting compared to the untreated soil. Therefore, both methods can be cost effectively applied by the farmers.

 Bachelor Thesis from the year 2022 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 4.00, University of Engineering & Technology, Lahore, language: English, abstract: As the demand of energy is increased the oil and gas industry is continuously trying to develop innovative technologies which will be used to increase the production of oil and gas in future. Besides many enhanced oil recovery techniques are present, the sandstone acidizing has been significantly developed to contribute to the petroleum industry. In sandstone acidizing different acids and their combination are applied on the formation. This results in minimizing the near wellbore damage and improve the well productivity. In this project we have performed acidizing on the sandstone rock of Ranikot formation which is present in the Lower Indus Basin. Drilling machine with different drill bit sizes are used to obtain different core samples from the formation rock. We applied HCl and HF acid, and their combination on the sandstone rock. In this project we observed the sandstone acidizing mechanism with different acids and observed problems that occurs due to the application of different acids on the formation. The laboratory results shows that the acidizing perform well when we use the mud acid which is the combination of HCl and HF acid. In the case of HCl acidization, most of the sandstone rock samples completely dissolve in the acid recipe and lose the bulk volume. But in the case of HF acidizing the rock cannot dissolve in the solution but precipitation takes place.

 Seminar paper from the year 2022 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: A, Wollega University (Soil resource and watershed management), course: Seminar, language: English, abstract: The Organic fertilizer improves physical, chemical and biological activities of soil and inorganic fertilizer is usually immediately and fast containing all necessary nutrients that are directly accessible for plants. The objective of the present review is to assess the integrated organic and inorganic fertilizers on growth and yield of some selected cereal and tuber crops. The treatments included some selected combinations of organic and inorganic nutrient sources including farm yard manure, Compost, poultry manure and NPK application. Some experimental results showed that wheat, Maize, Teff, Potato, Carrot yield, yield components and soil Physico-chemical properties were significantly affected by the integration of organic and inorganic fertilizer sources. The highest Teff grain yield (3144.8kg ha-1) and biomassyield (12562.5kg ha-1) were obtained from the applications of half doses of vermicompost(4.8tha-1) which is based on recommended N equivalent and half doses of the recommendednitrogen and phosphorus fertilizers (34.5kg ha-1N and 30kg ha-1P that half dose contains)followed by 2846 kg ha-1and 11833.3 kg ha-1for grain yield and biomass yield, respectively.The preharvest organic and urea treatment significantly (P<0.05) affected the yield of carrot and the highest yield (11.33tha-1) of carrot was obtained due to preharvest organic and ureatreatment at the rates of 309 and 411kg/ha respectively while the lowest yield was recorded in the control treatment (4.9tha-1). The highest total tuber yield was attained in response tothe combined integration of the three fertilizers at the highest rates (120 kg N ha-1 + 92 kgP2O5 ha-1 + 30t CM ha-1).The lowest total tuber yield was recorded on plots without anyfertilizer application. Hence, the highest total tuber yield was about 3.6 fold higher than the lowest total tuber yield. Therefore, the results of seminar review revealed that integrated of inorganic and organic fertilizers could be the best strategy to mentain soil fertility and to enhance production of cereal crop and tuber yield crops.
