  • - En guide
    af Troels V. Østergaard
    128,95 kr.

    En rigt illustreret guide til de sten, du finder på stranden.DANSKE STRANDSTEN giver dig en let tilgængelig bestemmelsesnøgle, så du nemt kan finde frem til, hvor netop den sten, du står med i hånden, er beskrevet i bogen. Herefter guider Geolog Troels V. Østergaard dig gennem de forskellige typer af sten: sedimentsten, metamorfe (omdannede) bjergarter og vulkanske bjergarter. Og så giver han svar på en række interessante spørgsmål om de danske sten:  Hvor kommer de fra? Hvordan er de transporteret hertil? Hvad er vandreblokke? Hvor gamle er stenene? Hvorfor er der kun sten ved nogle af de danske strande? Og hvorfor er ikke alle sten runde?

    I denne lille håndbog får du en nem guide til at starte op med brugen af krystaller. Nynne Sommer forklarer step-by-step, hvordan du bedst vælger dine krystaller, hvad du skal være opmærksom på i forhold til købet, og hvordan du renser, oplader samt bruger dine krystaller. Derudover finder du lister over, hvilke krystaller og sten der ikke tåler sollys eller vand, samt hvilke krystaller der er potentielt giftige. Du får samlet alt, hvad du har behov for at vide for at gøre krystallerne til en spændende del af dit liv. Krystallernes historie ¨Krystallernes virkning Krystalfælden – falske krystaller, menneskeskabte og menneskebehandlede krystaller Valget af dine krystaller Krystalformernes forskellige virkninger Modtagelse, køb og rensning af dine krystaller Klargørelse af krystallerne inden brug Krystallerne i brugKrystaller, chakra, stjernetegn og numerologi Særlige forhold Uddrag af bogen Når du som person tager en krystal i hånden, vil din energi interagere med krystallens indre struktur, som vil resultere i, at den begynder at udsende disse omtalte vibrationsfrekvenser. Den energi, du udsender, indeholder også vibrationer, og det er både positive og negative energier, vi som mennesker kan udsende. Når du sidder med en krystal, som har lige netop den egenskab, du søger, vil den hurtigt modtage dine energier og sende vibrationsfrekvenser tilbage til dig og allerede dér begynde at arbejde med de problematikker, du måtte have, som krystallens egenskaber matcher. Vores celler reagerer kraftigt på disse vibrationer, og krystallens egenskab, som vi har valgt den for, vil hurtigt kunne interagere med de ramte områder, den skal hjælpe os med. Om forfatteren Nynne Sommer (f 1992). Med sin passion for krystaller og sten driver hun virksomheden Clair de Lune, hvor hun forhandler krystaller, sten, tarot-, engle- og orakelkort, røgelse og smykker m.m. Udover at være krystalformidler til dagligt er hun clairvoyant, vejleder og medium for afdødekontakt.

    En dag bliver diamanthandleren Sidsel Dalby Glerup kontaktet af en ukendt portugiser. Han vil have hende til at finde en sjælden lyserød diamant og har 20 millioner kroner at gøre godt med. Selv om der er noget lusket ved manden, begiver Sidsel sig ud på en hæsblæsende jagt efter den sjældne diamant. Hun ender på skipisterne i Schweiz, i hemmelige lokaler i Holland og på diamantbørsen i Israel, og først sent finder hun ud af, at manden spiller med skjulte kort.Undervejs i denne virkelige fortælling, tager Sidsel Dalby Glerup os med gennem diamanternes historie og videnskaben bag. Hvad er en diamant? Og hvorfor har vi mennesker gennem tusindvis af år været så fascineret af de høje karater, at de dyreste sten bliver solgt for flere hundrede millioner?Diamanten der kostede millioner er en beretning om eventyr og hemmeligheder. Om de spor af både glæde og blod, de værdifulde sten trækker efter sig i historiens løb. Det er en underholdende og autentisk bog, der gør læseren klogere på de mineraler, der skabes dybt inde i jorden over millioner af år.

    Selection of the best-fitting method is the most important aspect of mining in terms of techno-economic parameters. Since underground mining methods are techniques of recovering mineral deposits below the earth¿s surface, they require a large outlay of capital and technological investment. There is a wide variety of underground mining methods available, each having inherent requirements for applications. Each mining method demands specific mine development. To develop this mine and produce ore will necessitate certain amount of cost, and on the other hand generate certain revenues. Keeping the costs low and revenues high will maximise economic return. This book can be used as a reference for comparison of the approaches for underground mining method selection. The study seeks to deepen the understanding of each approach and its capability in identifying a suitable underground mining method.

    The Nation`s economy is dependent on the success of mining operations. Mining is the basic industry that extracts minerals, or processes them largely. Because of recent energy crises, for example, the production of coal and its processing for power generation has been taken on a renewal importance. The impacts of mining operation are complex and need extreme care to be taken on long term basis. The safer mining enterprise provides higher productivity.Unless there is a common understanding of terms, there can be considerable confusion in transmitting information and knowledge. This can be particularly vexing in the understanding of safety literature in which such terms as ¿injury¿ and ¿accident¿ are often used interchangeably. Furthermore, definitions of accidents and hazards adopted for classification purposes may not be detailed enough to use as a basis for hazard control.

    ¿¿¿¿¿They were first found in full variety at St. Thomas¿ Mount and Plallavaram, 10 miles south of Madras city; from quarries in these localities large quantities of rocks have been obtained for building and ornamental purposes in Madras. Subsequently the same rocks were found to make up the mountain masses of the Shevaroys, Nilgiris, the Palnis and the great ridge of high ground forming part of the Western Ghats, stretching southwards as far as Cape Comorin and reappearing above the sea level in Cylone¿.- the words by Thomas Holland on charnockite. The book is all about charnockites and associated gneisses from the Madurai Granulite Block of the Southern Granulite Terrain. Looked into its association and genesis with very conventional view point of petrography, PT paths and geochronology.

    Graphite is a common accessory mineral in high-grade metamorphic rocks, but it is more prominent in khondalites (garnet-biotite-silliminite gneiss) and leptinites (garnet-biotite gneiss) and very rarely in garnet bearing and orthopyroxene bearing anhydrous granulites (charnockite). This fact is more pronounced and can be noted in rocks from the Southern Granulite Terrain, especially in Kerala Khondalite Belt. Both syngenetic and epigenetic types of graphite have been reported from this area. In the Madurai Granulite Block (MGB), the presence of khondalites and leptinites are comparatively less and the major rock type is charnockite with very rare amounts of garnet. But graphites are mineralizing in many parts of the MGB mostly within the charnockites or associated gneisses. The nature and type of this graphite has not been studied much. The book is an initiation to elucidate the graphite mineralization in the terrain with an emphasis on its genesis and mineralogical characteristics.

    This two books are perfectly suitable for petroleum engineers who are trying to do related tests for job and also other certificate e.g. Society of petroleum engineering exams. The author's worldwide experiences working with so many companies and being a part of educational system at many universities worldwide e.g. Middle East Technical university, Universiti Teknologi PETRONAS, Petroleum University of technology, Bergen University and Australian college or Kuwait makes the book to be amazingly practical for all petroleum engineers worldwide. The authors and editor are wishing all the petroleum engineering students to take the most advantage of this book which does have lots of interesting and just practical and technical questions and to be able to do come up themselves to solve them and to be ready to take any challenging exams. The team of authors just remembering the time they were students and they did not have such an amazing book to practice with otherwise they could be much stronger than what they are today. Hope this book can change our beautiful oil and gas industry to make it much better and stronger with the best graduated well rounded petroleum engineers.

    Reservoir heterogeneity was uncovered to perform an important role in the variation of components, as well as the transfer of heat within the reservoir. It was also observed that because convection and di¿usion in non-producing reservoirs are relatively slow processes and the di¿usion terms are small in magnitude, the e¿ect of variable di¿usion coe¿cients was termed negligible. Other observations include a consistency in the results obtained irrespective of the grid size used, for example, the three-dimensional grids produced the same average pressure, temperature, composition and velocity pröles as the 2-dimensional grids for certain reservoir con¿gurations.This study rummage-saled the general mass and energy balance equations to simulate ¿uid movement within a non-producing reservoir with thermal gradients. The con¿guration of ¿uid components and heat within the reservoir is characterized using various metrics such as the Nusselt and Rayleigh numbers, as well as separation and density factors. These metrics are able to show, in a concise manner, the e¿ect of changes in the reservoir and ¿uid properties on compositional variations.

    Shari playa is a closed basin characterized by the development of seven sedimentary facies and five sedimentary subenvironments over the underlying clastic substrata facies. The sediments distribution and geometry indicate that the playa is a subsiding N-S oriented graben. The area show three sets of lineaments oriented NW-SE, NE-SW and N-S directions. A set of N-S step faults, partly affected by the other trends of lineaments, seems to control the subsidence and orientation of the graben. The age of the depression is suggested to be 6000-6500 years B.P. deduced from the palynological studies, assumed rates of precipitation and comparison with palaeoclimatic trends. Saline minerals found in the Shari Playa are: gypsum, glauberite, halite, thenardite and trace amounts of bassanite, natron, trona, huntite, d'ansite and hydrated magnesium brormide. They mainly occur in the facies that occupy the central part of the playa. The main saline minerals in the playa show spatial and vertical distribution reflecting the playa lake brine evolution and concentration following characteristic paths on the system CaSO4 - Na2SO4 ¿ NaCl - H2O.
