Microstructural Constraints On The Nebular And Asteroidal Histories Of Calcium-Aluminum-Rich Inclusions From Cv3 Chondrites, Shaofan Che

Earth and Planetary Sciences ETDs

The petrology and mineralogy of calcium-aluminum-rich inclusions (CAIs) from CV3 carbonaceous chondrites have been investigated using transmission electron microscopy (TEM). The goal of this dissertation is twofold: (1) to gain new insights into the nebular processes, such as vapor-solid reactions, accretion, transport, that are responsible for the formation of non-igneous CAIs, and (2) to better understand the role of fluid in the secondary alteration of CAIs on the CV3 chondrite parent body. This work represents the first systematic microstructural study of CAIs from CV3 chondrites.

Chapter 2 presents the microstructural observations of primary mineralogies of fine-grained, spinel-rich inclusions (FGIs) from …

Pertumbuhan Dan Hasil Benih Kentang G0 Kultivar Medians Pada Berbagai Komposisi Media Tanam Dan Interval Pemberian Air Di Dataran Medium, Jajang Sauman Hamdani, Sumadi, Kusumiyati, Haifa Ruwaidah

Jurnal Kultivasi

Benih merupakan kunci sukses budidaya kentang. Salah satu faktor yang mempengaruhi dan menjadi kendala produksi kentang di Indonesia adalah ketersediaan benih kentang yang memiliki kualitas dan kuantitas baik serta belum memenuhi kebutuhan permintaan benih petani kentang. Permasalahan produksi benih kentang generasi ke-0 (G0) adalah rendahnya jumlah ubi benih yang dihasilkan. Percobaan ini bertujuan untuk mengetahui interaksi antara komposisi media tanam dengan interval pemberian air terhadap produksi benih kentang G0 di dataran medium. Percobaan dilaksanakan di Kebun Percobaan, Fakultas Pertanian, Universitas Padjadjaran, Kampus Jatinangor. Rancangan percobaan yang digunakan yaitu Split Plot. Petak utama adalah komposisi media tanam yang terdiri dari campuran …

A Survey On Subsurface Signal Propagation, Usman Raza, Abdul Salam

Computer Information Technology Faculty Publications

Wireless Underground Communication (WUC) is an emerging field that is being developed continuously. It provides secure mechanism of deploying nodes underground which shields them from any outside temperament or harsh weather conditions. This paper works towards introducing WUC and give a detail overview of WUC. It discusses system architecture of WUC along with the anatomy of the underground sensor motes deployed in WUC systems. It also compares Over-the-Air and Underground and highlights the major differences between the both type of channels. Since, UG communication is an evolving field, this paper also presents the evolution of the field along with the …

Petrology Of The Gradational Intrusive Contact Between The Packsaddle Schist And The Town Mountain Granite, Enchanted Rock State Natural Area, Llano Uplift, Central Texas, Travis Galle

Electronic Theses and Dissertations

The Mesoproterozoic intrusive contact between the ~1.1 Ga anorogenic Town Mountain Granite and the ~1.3 Ga Packsaddle Schist is a gradational contact exhumed within the Llano uplift. This contact is exposed along the southeastern margin of the Enchanted Rock batholith in central Texas. Field observations, hand sample and thin section petrography, and handheld X-ray fluorescence analysis of hand samples were used to characterize the gradational nature of this contact at multiple scales. The style of gradation between the Town Mountain Granite and Packsaddle Schist varies throughout the study area, containing both injection and permeation. The complex relationships observed at the …

Niche Dynamics Of The Felid Guild Following The Pleistocene Megafaunal Extinction, Nicholas A. Freymueller

Biology ETDs

The loss of large carnivores is fundamentally restructuring modern mammal communities. However, large carnivore removal is not exclusively a modern trend. The Pleistocene Megafaunal Extinction (PME) resulted in a near-eradication of hyper-carnivorous felids such as saber-toothed cats. However, it is unclear if smaller surviving meso-felids began to infill this ecological vacuum post-PME. I apply Ecological Niche Modeling (ENM) to test evaluate whether surviving felids filled in vacant niches post-extinction, and hypothesize that they ought to have shown increased niche-overlap patterns with mega-felids post-extinction. I model species’ fundamental niches using a multi-temporal approach, and develop a novel test to model realized …

The Age And Origin Of Precambrian Orthogneiss Of The Grouse Creek Block, Northern Utah And Southern Idaho, Skadi Kobe

Fall Student Research Symposium 2020

New geochronologic and isotopic analyses from the Grouse Creek block (GC) provide insight into the assembly of western Laurentia during the late Archean to Paleoproterozoic and establish the influence of the GC in the evolution of Yellowstone-Snake River Plain hotspot magmatism in the central Snake River Plain. The GC is primarily exposed in the Albion-Raft River-Grouse Creek metamorphic core complex of northern Utah and southern Idaho and includes a complex assemblage of orthogneiss, schist, amphibolite, and metasediments intruded by Oligocene plutons and overlain by Cenozoic sedimentary units. Many investigations of the GC have focused on the structural evolution of the …

Usu Professor David Rosenberg Spearheads Asce Efforts To Encourage Research Reproducibility, Utah Water Research Laboratory

News

The American Society of Civil Engineers (ASCE) recently announced a new program with the Journal of Water Resources Planning and Management that will recognize and reward authors who make their research results more reproducible. As an associate editor at ASCE and Professor in civil and environmental engineering at USU and the Utah Water Research Laboratory (UWRL) at USU, Dr. David Rosenberg was instrumental in creating this new program. He has been studying the importance of reproducibility in research results and advocating for the concept for years.

Relationships Between In-Situ Tests And Soil Cyclic Strength For Earthquake Hazard Characterization In The Pacific Northwest, Tanner Scott Bryantt

Dissertations and Theses

Strong earthquake shaking is a natural hazard threat in the Pacific Northwest. Soil failure due to strong earthquake shaking -- known as cyclic soil failure or liquefaction -- is expected to cause large ground deformations and damage to roads, bridges, and other civil infrastructure. Cyclic soil strength (CRR) is often characterized with in-situ geotechnical tests including the cone penetration test (CPT). Relationships between CRR and in-situ test data are not well established for soils in the Pacific Northwest. Portland State University, in partnership with New Albion Geotechnical has compiled a database of cyclic lab tests for Pacific Northwest soils to …
