Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Master's Thesis from the year 2008 in the subject Chemistry - Physical and Theoretical Chemistry, , course: Physics, language: English, abstract: Elemental boron has a fascinating chemical versatility that is unique among the elements of the periodic table. The study of the evolution of boron atomic clusters and their chemical and physical properties is of fundamental interest to researchers interested in nanotechnology. One of the most difficult problems in the study of boron clusters is finding their ground state cluster structures. The atomic arrangements in clusters are generally very different from those in corresponding bulk materials, such that chemical intuition cannot be trusted to generate optimal structures. An unbiased search method was used to search for these stable boron structures. It took advantage of the relative speed of the density functional-based tight binding (DFTB) method to identify low-lying local structures and then used the more accurate density functional theory (DFT) to find the ground state structures.In this project we used a computational scheme to predict the best atomic arrangements of boron clusters. A completely unbiased search mechanism was implemented to determine optimal boron clusters. An approximate model was first used to locate minimum energy conformations followed by a more accurate first principles calculation to get the global minimum. Our results were then validated by comparisons to those reported in literature. The objective was to perform a consistent search of cluster sizes ranging from sizes n = 2-14, 16, 18 and 20. This was done to not only study where boron makes its transition from flat to three-dimensional clusters, but also to determine patterns in their evolution with size. The motivation behind our work and the long-term goal involved exploring the viability of the existence of large cage-like boron clusters, like B80, which have been proposed in literature as being extremely stable.…

Would there be any survivors The 20th century was dominated by ethnic, race, political and religious struggles and conflicts; the 21st century has vastly inherited the problem with a huge shift in attitude and preference, but in all this, what is the future for Persons with Disabilities in a world of alternative lifestyles, eugenics, euthanasia, acclaimed United Nations human rights and conventions sequel to 'The Bright Dark Nights Of The Soul' book - (2013) script, the author a recipient of the 'Pro Ecclesia' gold medal award from the late Saint Pope John Paul II avails for posterity diaries and points for reflections on cultural and humanitarian perspectives impacting on aspects of existential crisis, search for meaning and purpose for persons with Disabilities deeper into the 21st century. With contributions and insights from Corporate social responsibility initiatives, scholars, clergy, custodians of persons with disabilities, persons who lived in the 19th and 20th century in Africa: Some who served in the American Peace Corps in 1960's Africa, encounters with so called - 'natives' and 'savages', War Veterans and members of the armed forces, multicultural religious and missionary icons, contemporary peace and outreach initiatives from international religious, secular and political leaders: Towards this end, a case study paper in the United States on a Disabilities outreach project in Africa is availed in Six language translations, French, Spanish, Portuguese, English and the Luo and kikuyu African Languages to hopefully stimulate further multicultural reflections and action in the diaspora communities towards persons with disabilities.…

Zustand: Hervorragend. Zustand: Hervorragend | Seiten: 52 | Sprache: Englisch | Produktart: Bücher | Invasive species are a major ecological and management concern in natural ecosystems and pose a threat to many habitats. Invasive plant species compete with native species phasing them out of their niches and times leads to loss of ecosystem services such as water filtration, soil stabilization, and pest control. They may also result in reduction of wildlife forage, death of wild animals due to lack of food or at times death of wild animals when they feed on poisonous invasive plant species. Invasion of native plant habitats change the macro-nutrients and the micro-nutrients by invasive plant and this changes soil chemicals. The aim of this study was to establish whether the invasive plant Lantana camara changes the soil chemical properties. The key objective was to evaluate the soil nutrient composition in areas invaded by Lantana camara L. and how these differ from areas without Lantana camara.…
