Paleoepidemiology Of Bacterial Infections Among Prehistoric Human Populations In Northern Chile: An Ancient Dna Approach, Luz-Andrea Pfister
Paleoepidemiology Of Bacterial Infections Among Prehistoric Human Populations In Northern Chile: An Ancient Dna Approach, Luz-Andrea Pfister
UNLV Retrospective Theses & Dissertations
Bacterial pathogens not primarily affecting the skeleton but causing sepsis and death, have not been systematically studied in prehistoric human populations, although increasing evidence support our species long co-evolution with many of them. With molecular methods we can identify bacteria at the species level and distinguish pathogenic from environmental and soil bacteria. Bone marrow of ancient people may provide valuable information about ancient pathogens causing sepsis and death. To test the hypothesis that PCR amplification using universal bacterial primers will identify prehistoric bacterial pathogens in bone marrow, 30 samples were aseptically obtained from partially mummified remains of three archaeological sites …
Effect Of Low Level Laser Therapy On Migration Of Human Skin Cells Across A Standardized Wound, Kathleen Orzechowski
Effect Of Low Level Laser Therapy On Migration Of Human Skin Cells Across A Standardized Wound, Kathleen Orzechowski
UNLV Retrospective Theses & Dissertations
The purpose of this study was to examine the effects that different dosages of low level laser therapy have on human skin cell migration. Normal newborn foreskin fibroblasts were seeded into a four well chamber microscope slide. Cellular monolayers were inflicted with three standardized wounds per well. Following the wounding of cells, each well received low level laser therapy once from a 635 nm laser at one of four treatment dosages (0.0 J/cm 2, 1.0 J/cm2, 1.5 J/cm2, 2.0 J/cm 2) with a power output of 11.5 mW. Digital images were recorded immediately following wounding, and every hour thereafter for …
Application Of Computational Fluid Dynamics For High Energy Efficiency Design With Human Comfort Of Cad-Vav And Ufad Systems, Bhanu Rekha Bandhakavi
Application Of Computational Fluid Dynamics For High Energy Efficiency Design With Human Comfort Of Cad-Vav And Ufad Systems, Bhanu Rekha Bandhakavi
UNLV Retrospective Theses & Dissertations
This thesis deals with the numerical simulation of the ceiling air distribution (CAD) system and the Under Floor Air Distribution (UFAD) system based on the dimensions of BTLab at UNLV. Ceiling Air Distribution (CAD) with variable air volume (VAV) and Under Floor Air Distribution (UFAD) systems have been widely used in different countries. CAD-VAV and UFAD systems designs have been influenced by increasing emphasis on indoor air quality (IAQ), energy conservation, environmental effects, safety, and economics. So, 3-D Computational Fluid Dynamics (CFD) analysis technique was applied to design high energy efficiency and human comfort CAD-VAV and UFAD systems. The goal …
