ISBN: 9789400729407 / Angielski / Twarda / 934 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Genesis - In The Beginning deals with the origin and diversity of Life and early biological evolution and discusses the question of where (hot or cold sources) and when the beginning of Life took place. Among the sections are chapters dealing with prebiotic chemical processes and considering self-replication of polymers in mineral habitats. One chapter is dedicated to the photobiological regime on early Earth and the emergence of Life. This volume covers the role of symmetry, information and order (homochrial biomolecules) in the beginning of Life. The models of protocells and the...

Evaluation of Geospatial Distribution of Secondary Schools
ISBN: 9783846582626 / Angielski / Miękka / 92 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Spatio-temporal information on schools is fundamental to school management especially in urban centres where the population and other anthropogenic activities are concentrated. However, the creation of balanced urban educational establishments requires adequate and up to date information on the interrelationship between educational facilities and other environmental factors. The adequacy of the data is imperative in aiding decisions that ensure that scarce resources are adequately directed to the sections of the town where they are most needed. School planners and managers in Nigeria since...

Tree Planting Prioritisation Using GIS and MCA
ISBN: 9783845419855 / Angielski / Miękka / 92 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This Study describes a methodological approach based on the use of GIS and multi criteria analysis to identify Tree planting sites in Manchester. A set of criteria were defined to evaluate tree planting sites. After defining the criteria, next step was to selecting suitable indicators and variables to measure the selected criteria for analysis. Later on these criteria were ranked using the pair wise comparison method of multi criteria analysis and results was integrated into GIS. Multi criteria analysis and GIS is an effective approach for GIS decision makers as it allows one to gradually...

Trace Elements in Soil Pore Water
ISBN: 9783838306827 / Angielski / Miękka / 296 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book examines a range of methods for sampling soil pore water to investigate the chemistry of trace elements. In particular, the study assessed whether Rhizon samplers, centrifugation, high pressure squeezing and soil suspensions in simulated pore water can be viable approaches for obtaining representative samples of equilibrated soil pore water. Results for metal solubility and speciation were interpreted in terms of both soil morphological effects on trace metal dynamics and artefacts introduced at various stages during sample preparation and handling. Pore waters showed different...

Fate of Volatile Fluorinated Compounds in the Subsurface
ISBN: 9783838309545 / Angielski / Miękka / 188 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Since their discovery around 1930, the synthetic compounds of the class of chlorofluorocarbons (CFCs) have been produced and used worldwide at very large scale. Their physico-chemical properties have made them ideal candidates for several applications, such as refrigerant fluids, aerosol propellants, foam blowing agents, or as solvents or intermediates in chemical synthesis. This resulted in their wide distribution in the atmosphere, where they were recognized in the 70 to be implicated in the process leading to the stratospheric ozone hole, but also in other environmental compartiments such...

GIS for Fire Management
ISBN: 9783838316840 / Angielski / Miękka / 64 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The use of fire as a management tool is a challenging issue for conservation managers. The identification of critical areas for prescribed burning is of extreme importance due to the limited resources available for this purpose. A Geographical Information System (GIS) has been developed to model and quantify fire threat in Litchfield National Park. The important factors favouring fire conditions, particularly probability of ignition and fire behaviour, were combined to demonstrate the spatial variation in the levels of threat in the Park. Outputs of the model include the...

A study on the amelioration of soil acidity for ananas comosus L. cultivated on bris soil was conducted in pot and also in the field using Rhudua series soil. The experiment was arranged in Randomized Complete Block Design (RCBD) with six treatments and four replications. This involved application of Ground Magnesium Limestone (GML) to neutralize the acidity of sandy soil. GML was applied in four equal split doses at six different rates of 0, 0.5, 2, 4, 8 and 10 Mgha-1. The results showed positive effect on soil pH (H2O); P, Ca and Mg concentrations in the soil; Ca, Mg and Cu concentration in...
