This dissertation is divided into two major chapters. The first chapter covers the geologyof the Encuentro deposit with emphasis in the intrusion sequence, vein mineral assemblages and distribution, and age of mineralization. The data used for this section includes field mapping, petrography, elemental analysis of biotite, and isotopic geochronology. The...
Indonesian tuna fisheries are complex due to variation in the scale of fleet in the fisheries, their multi-species nature and problems with data collection. Moreover, like many developing-country fisheries, their management needs to take into account many other goals besides rents maximization, such as the distribution of rents and the...
BaCuChF (Ch = S, Se, Te) materials are chalcogen-based transparent conductors with wide optical band gaps (2.9 – 3.5 eV) and a high concentration of free holes (10¹⁸ – 10²⁰ cm⁻³) caused by the presence of copper vacancies. Chalcogen vacancies compensate copper vacancies in these materials, setting the Fermi level...
During the peripartum period (3 weeks before through 3 weeks after calving, a.k.a. “transition”), high producing dairy cows experience, among others, , oxidative stress and immune suppression that compromise performance and increased incidence of diseases.Among trace minerals, supplementation of Selenium (Se) can help to improve the transition by enhancing glutathione...
Wheat (Triticum aestivum) is an important crop worldwide, however, in recent years concerns have been raised regarding two health issues, celiac disease and gluten sensitivity, and their relationship to wheat consumption. This increase has led to questions regarding potential changes over time in the composition of gluten (glutenin and gliadin)...
REDD+ is a heavily promoted mechanism to mitigate climate change through the carbon market worldwide, however, initial projects presented challenges related to effectiveness, efficiency, and equity (3E criteria) during implementation. In Peru, it has been promoted since 2008 due to high deforestation rates in the tropical forest, with 30 ongoing...
Since the decline of salmonid populations in the Pacific Northwest, supplementation programs have become frequently implemented by hatcheries as a way to protect and conserve wild stock. However, hatchery-reared fish have lower fitness than wild fish which is likely due to adaptation to the hatchery environment, i.e., domestication selection. Fish...
This essay provides a snapshot of sustainability and acceptability of wave energy and eight other electricity-generating energy sources in Oregon. Since “sustainability” is an important point of view in decision-making, the paper is centered around the concept. Although there is no consensus on the definition of sustainability in the academic...
