The paper analyses various processes of water transport in a glaciated system. It focuses on measuring cycles and processes of water transport in different glacier sub-systems in the ablation season of 2006. The glacier itself is seen as the element of retardation of run-off and storage. The spotlight is on measuring retention times and quantities as well as understanding interactions of subsystems. Infiltration processes and the progress of the melt front were investigated by the applicaton of coloured dyes on snow and firn. The study emphasized on fluorescent dye tracer measurements to investigate retention times of water for different parts of the glaciated basin. Dye measurements under snow on firn showed significantly reduced flow velocities in comparision to later en- and subglacial flow measurements. To measure the englacial flow of water, again fluorescent dyes were used. From measured data, flow rates under snow, on firn and ice as well as flow velocities in the main englacial and subglacial channels were derived. Meteorologic and hydrographical data from the Sonnblick Observatory the nearby gauge station were used to support analyses and results.
Cancer is a complex disease that is characterized by cell proliferation (uncontrolled cell division), cell transformation and an escape from apoptosis and these properties pave the way for invasion, angiogenesis and metastasis. Additionally, cancer has also emerged as a major public health problem in developing countries. According to the World Health Organization, new cases of cancer impairment will increase with estimated death rates of up to 11 million in the year 2030. Although in recent decades much progress has been achieved in respect of therapies, like surgery, chemotherapy, radiation or hormone ablation therapy, they are not successful in more than 50% of cases. Furthermore, for those who survive the risk of reoccurrence of the disease is a major problem. Breast cancer is one of the most prevalent malignancies among women worldwide. The existing therapeutic agents for breast cancer produce several side effects. Development of specifically breast cancer cell targeting drug without any side effect to normal cells is an ongoing effort in the field of cancer drug discovery. Cytotoxic chemotherapy plays a vital role in the management of patients.
Perhaps no earlier technology has been as interested and anticipated as the nanotechnology, which is the magic key to progress in science and knowledge. The applications of nanotechnology are not limited to one branch of science but extend their applications to all branches and applications. The production of nanoparticles by way of laser ablation of solids in both gas or vacuum and liquids have been widely explored over the past two decades. The method of laser ablation has received considerable attention as a new technique for the production of nanoparticles. Which represent the phenomenon of the interaction of the laser with the material, since the amount of mass removed depends on the Laser parameters (pulse duration, number of pulses, energy, wavelength, properties of the target material, surrounding environment).
This book, now in its second edition, provides a comprehensive analysis of imaging of the kidneys, upper urinary tract, and ureters, covering the normal anatomy and anatomic variants as well as all renal and urinary system pathologies. The relevant imaging modalities are first discussed, with detailed description of their applications. The entire spectrum of kidney pathologies is then presented in a series of detailed chapters with up-to-date references, high-quality images, informative schemes, and figures showing macroscopic and microscopic surgical and pathologic specimens. Chapters relating to the latest innovations in tumor ablation, vascular and nonvascular interventional procedures, and parametric and molecular imaging have been updated to reflect progress in these rapidly evolving fields. This book will be of great interest to all radiologists, oncologists, nephrologists, and urologists who are involved in the management of kidney pathologies.
