Lateral Interactions of Corroding Pits
… the above experimental conditions showed that pits do interact with each other and that the surrounding pits serve to stabilize the central pit and affect its lateral growth. Pit interactions was influenced by the distance of neighboring pits, number of pits and bulk concentrations of pH and …

Study of Corrosion Pits in Chloride Solution
… technique was used to initiate single corrosion pits as well as geometrically ordered arrays of pit on nickel (99.99%) immersed in 0.5 M NaCl solutions under potentiostatic condition. The current was measured during pit growth and the shape of each pit was recorded upon termination of each …

A typology of pits on the Engelbert site
… analysis is the pit. In the pages which follow, pits are treated as artifacts. They are described, classified, and viewed in time and space as any other class of artifact. The main focus of the essay is typological. Since pits are empirical objects, they have attributes which vary in time and …

Study of Single Corrosion Pits on Aluminum in Chloride Media
… state of the metal surface of aluminum pits in aqueous chloride solutions, and the mechanism of rate control of the subsequent corrosion reaction. Novel experimental techniques, including UV and NMR spectroscopy, were used to study the pit chemistry. Results obtained by chemical analysis …

Mosh pits and mental health: metal communities and emerging adults' well-being
In this thesis I will examine relationships between metal music and community participation and the mental well-being of so-called "emerging adults" within these communities. Building upon previous research on these relationships, I examine how emerging adult mental well-being is affected – both …

Hydrogeomorphology of Lava Rise Pits in The Laki Lava Field, Southeast Iceland
Lava Rise Pits (LRPs) are found within the Laki lava field in Southern Iceland. LRPs naturally occur in pahoehoe lava flows and form when the flow in lava tubes ceases and collapses. The goal of this study was to better understand the hydrogeomorphology of LRPs during the Fall-winter season. Three …

Production of activated carbon from date palm pits and its use in industrial wastewater treatment
… granular activated carbon (GAC) from date palm pits, a waste material. Reported data indicates.that the t. yearly production of dates in the Kingdom of Saudi Arabia (KSA) is more than 800 ktonnes of which a significant portion is de-stoned prior to sale. Hence the use of date palm pits for the …

Fire on the Mountain: Roasting Pits in the Sheep Range on the Desert National Wildlife Refuge
Roasting pits are earth oven facilities commonly found scattered throughout southern Nevada. The term earth oven refers to the process or event of baking foods, often plants, in a cooking pit with hot rocks which is covered by an earthen cap. While roasting pits were used to bake a variety of food …

Relationships between water quality, species composition, biodiversity and ecosystem function in lakes and flooded pits exposed to uranium mining activities in Northern Saskatechewan
… similar among the majority of lakes and flooded pits despite differences in species richness, species composition and species abundance. Only a small number of aquatic systems had ecosystem function properties that were different from the majority of lakes and pits. These systems had the greatest …

Talus Features of the Middle Columbia River: Typological and Locational Analyses
… circular to oval in shape, are called talus pits. Pit features are also located in colluvium and alluvial fans, and at the base of cliff overhangs. Over 568 of these features have been documented for 48 sites within the project area of the Priest Rapids and Wanapum reservoirs. Pits may have …
