Uncertainties about landscape evolution under cold, nonglacial conditions raise a question fundamental to periglacial geomorphology: what and where are landscapes? To answer this, with an emphasis on lowland areas, the present study distinguishes between characteristic polygenetic landscapes, considers how complete is footprint of periglaciation? Using conceptual framework sensitivity change, a...

Introduction: Lobate debris aprons (LDA) and lineated valley fill (LVF) surrounding plateaus and isolated massifs have been documented in numerous locations in the northern mid-latitudes on Mars [1-8]. While there has been agreement that these features represent Amazonian-aged modification of the dichotomy boundary from ice-assisted debris flows [e.g., 9], the amount of ice and mode of origin o...

In this investigation, high resolution MOC images were examined to document the meterscale surface textures on lobate aprons and valley floors within Dueteronilus Mensae. The spatial distribution of four meter-scale surface textures exhibits a latitude dependence with knobby terrain more prevalent at lower latitudes and pitted terrain more common at higher latitudes within the study region. Thi...

Hot springs in the Alvord/Pueblo valleys southeastern Oregon are analogous to Basin-and-Range hydrothermal systems where heat source and permeable pathways met through crustal thinning. Silica sinter deposition at Mickey Springs, Alvord Valley, predates late Pleistocene high stand of pluvial Lake Alvord. At Borax Lake, Pueblo occurred during Holocene. This study examines evolution three morphol...

The health care workers should be aware of Universal Work Precaution (UWP) as there is an increased risk of exposure to infectious diseases which is considered mainly due to accidental exposure to blood and body fluids. This study mainly aims to evaluate the knowledge, attitude and practice of medical students on blood and body fluids at Gulf Medical University, Ajman, United Arab Emirates (UAE...
