Streszczenie:
The amount of runoff generated relative to different surface types given an amount of rainfall is very important in hydrogeomorphological studies. This study is aimed at examining sediment yield responses to rainfall on different surfaces in Obudu, Cross River State, Nigeria. Data were collected on rainfall amount, intensity, duration and sediment loss from three run off plots on natural vegetation surface, mulched and bare surfaces. The data collected were analyzed using Pearson’s moment correlation and multiple regression statistical techniques. The results revealed that rainfall amount corr

Digital elevation models (DEMs) have shown much potential for use in the extraction of land surface parameters and analysis of the relationship between land surface units and vegetation cover. However, there is lack of studies on the use of SRTM-3 DEM in vegetation studies of mountainous regions. This study is therefore an attempt to relate land surface parameters to vegetation cover in the Obudu mountain region using SRTM-3 DEM and Landsat data.

As part of the Colours of the Outer Solar System Origins Survey (Col-OSSOS), we have obtained g-, r-, and z-band photometry of 26 TNOs using Subaru and Gemini Observatories. Previous color surveys have not utilized z-band reflectance, and the inclusion of this band reveals significant surface reflectance variations between sub-populations. The colors of TNOs in g - r and r - z show obvious structure, and appear consistent with the previously measured bi-modality in

Using the concept of the ‘braid type’ of a periodic orbit, its relation to Artin’s braid group, and the Nielsen-Thurston classification of surface homeomorphisms, we examine problems pertaining to the coexistence of periodic orbits, in particular for homeomorphisms of the disc, annulus and 2-torus.

This thesis describes the results of two spectral studies of T Tauri stars. T Tauri stars are young, low mass, stars which have yet to evolve to the point where Hydrogen fusion occurs in their cores. They are normally found in groups associated with gas clouds in locations called star forming regions. Much work has been done to explain the bizarre spectral features of T Tauri stars, and this has led to the development of a standard model for their structures. Classical T Tauri stars are thought to be surrounded by large discs of accreting material, which slowly adds to the mass of the star. Th

ABSTRACT Offshore platforms in the Gulf of Mexico are in a very corrosive environment and the maintenance coatings require regular attention. Coating maintenance should progress at a reasonable rate to preserve the integrity of the operating facilities. Since the bulk of the time is spent on surface preparation and coating application, if the time for these two activities could be reduced with a less degree of surface cleanliness without too much compromising corrosion mitigation and coating life, this will be of great benefit, providing a higher success of being ahead of the painting program

Abstract Surface conditioning is the first step in building efficient corrosion protection on a part or structure. Key concerns during this step include, how to create a stronger anchor-profile and how to efficiently remove previously coated, damaged, or corroded elements from a materials surface prior to coating. The ideal solution must consider three areas of the surface conditioning process: finish quality, cleaning efficiency and total cost. This study compares the performance of various blasting media used for surface conditioning. Considered media includes a new engineered ceramic media,

abstract A discussion on the issues and challenges related to surface preparation in the field. As means and methods diversify and structures types become more complex, challenges arise. This presentation attempts to identify some of the potential issues and challenges associated with today’s modern methods of surface preparation in the field. Some potential issues for discussion include: abrasive selection, use and reuse, waste management and disposal, containment, degree of surface cleanliness, substrate type and existing condition, zone painting vs. full rehabilitation and scheduling confli

Abstract Scaling, which is the formation of insoluble inorganic solids, is a major problem in water treatment plants and in the oil industry. Millions of dollars are spent each year to prevent the occurrence of scale. Calcium carbonate (CaCO3) and barium sulfate (BaSO4) are common types of scale encountered in these sectors. Scale predictions are typically based on thermodynamics and tend not to give a time-based quantification of surface scale growth. Recent work clearly demonstrated that scale deposition and precipitation are two different processes and that their rates should be evaluated s

This research considers the detection, location, and classification of patches in concrete and asphalt-on-concrete pavements using data taken from ground penetrating radar (GPR) and the WayLink 3D Imaging System. In particular, the project seeks to develop a patching table for “inverted-T” patches. A number of deep neural net methods were investigated for patch detection from 3D elevation and image observation, but the success was inconclusive, partly because of a dearth of training data. Later, a method based on thresholding IRI values computed on a 12-foot window was used to localize pavemen

There is a need for renewable antimicrobial surface treatments that are semi- permanent, can eradicate both biofilms and planktonic pathogens over long periods of time and that do not select for resistant strains. This proposal describes a dopamine binding technology that is inexpensive, bio-friendly, non-toxic, and uses straight-forward commercially available products. The antimicrobial agents are peptidoglycanhydrolase enzymes that are non-toxic and highly refractory to resistance development. The goal of this project is to create a treatment that will be applicable to a wide variety of surf

SAGE-PEDD is a computational model for estimating snowdrift shapes around buildings. The main inputs to the model are wind speed, wind direction, building geometry and initial ground or snow-surface topography. Though developed mainly for predicting snowdrift shapes, it has the flexibility to accept other soil types, though this manual addresses snow only. This manual provides detailed information for set up, running, and viewing the output of a SAGE-PEDD simulation.
