Synchrotron X-Ray Visualisation Of Ice Formation In Insects During Lethal And Non-Lethal Freezing, Brent J. Sinclair, Allen G. Gibbs, Wah Keat Lee, Arun Rajamohan, Stephen P. Roberts, John J. Socha

Biological Sciences Faculty Research & Creative Works

Although the Biochemical Correlates of Freeze Tolerance in Insects Are Becoming Well-Known, the Process of Ice Formation in Vivo is Subject to Speculation. We Used Synchrotron X-Rays to Directly Visualize Real-Time Ice Formation at 3.3 Hz in Intact Insects. We Observed Freezing in Diapausing 3rd Instar Larvae of Chymomyza Amoena (Diptera: Drosophilidae), Which Survive Freezing If It Occurs above 214uC, and non-Diapausing 3rd Instar Larvae of C. Amoena and Drosophila Melanogaster (Diptera: Drosophilidae), Neither of Which Survive Freezing. Freezing Was Readily Observed in All Larvae, and on One Occasion the Gut Was Seen to Freeze Separately from the Haemocoel. There …

Creation Of Soil Liquefaction Susceptibility Maps For San Luis Obispo & Marin Counties Using Geographic Information Systems., Amelia M. Lowman

Earth and Soil Sciences

Liquefaction of soils in response to earthquake shaking is a pressing issue in the state of California. Using Geographic Information Systems, Geological and lithology layers, along with criteria in order to separate out the data into four risk categories, a liquefaction risk assessment map was created for San Luis Obispo and Marin Counties. The accuracy of these maps was then assessed using liquefaction occurrences for San Luis Obispo County, and it was determined that while the map is somewhat accurate, in order to obtain a greater amount of accuracy and increase the usefulness of these maps, more data would need …

Algae As An Economical Protein Source For Dairy Cattle Nutrition, Brian Azevedo

Dairy Science

Dairying continues to change with economic and environmental demands of today’s fast moving society. Feed costs continue to rise and now account for a large majority of expenses on dairies; especially protein, which has become expensive to purchase. I believe that Algae can serve as a possible solution to aid in alleviating this problem. Algae grow rapidly and consume undesirable carbon dioxide to release oxygen to the environment, making it an environmentally friendly source of feed. There are particular strands of algae that are high in protein. During the course of this project, I intend to discover how effective protein …

Usage Of The Penn State Forage Separator For Evaluating Particle Size Of Tmrs, Ashley Rene Garcia

Dairy Science

Particle size has many effects on the cow. Adequate forage particle length is necessary for proper rumen function. Dairymen are also having a hard time measuring particle size. Proper particle size distribution of feeds is an important part of ration formulation. Management of forage particle size starts with harvesting forages at the proper stage of maturity. Chopping the crop at the right length helps to achieve the desired particle length in a TMR. Measuring particle length of the forages is only a portion of the solution. Analyzing the TMR particle size is the main goal in measuring the distribution of …

Development Of Regional Hydraulic Geometry Curves For The Santa Cruz Mountains, Sarah Howell

Natural Resources Management and Environmental Sciences

This study was conducted to develop regional hydraulic geometry curves for the Santa Cruz Mountains that could be used in stream related and/or engineering projects. Data used to form these curves was collected from the USGS and by conducting stream geometry surveys. The resulting regional curves had high R² values ranging from .82 to .92. Compared to other regional curves in nearby areas, the Santa Cruz Mountains regional curve equations have higher exponents, meaning bankfull channel measurements increase at faster rates as drainage areas increases. Further measurements and analysis should be done before applying these curves to project sites.

Cost Of Quality In The Construction Industry, Philip L. Barlow

Construction Management

The construction industry needs to decrease its costs due to nonconformance by implementing an objective model for analyzing the excessive cost of poor quality and the overall savings realized from good quality. Direct cost estimates from rework in commercial building construction average about 5%. A simple calculation based on U.S. construction industry expenditures of $1.246 trillion in 2007 reveals that $62 billion is wasted just on the direct cost construction rework alone! The term quality can be applied in many different ways to various aspects of the construction process. This paper proposes a model which helps illustrate how the various …

Student Sample Perceptions Of Organic Food Products And Buying Habits, Alycia M. Deus

Agricultural Education and Communication

The purposes of this senior project were to identify college students’ perceptions and knowledge of organic food. This study also focuses on the respondents’ purchasing and budgeting of organic food. This information is essential to inform farmers and ranchers because it serves as an indicator of future market’s demands.

A thirteen item questionnaire was distributed to sixty-five students attending California Polytechnic State University, San Luis Obispo, enrolled in either Agricultural Education and Communication courses or Agricultural Business courses. Both upper and lower division classes were surveyed. The questionnaires were distributed and collected from June 2, 2009 to June 4, 2009. …

Performance Based Analysis Of Steel Buildings, Matthew Joseph Williams

Master's Theses

This project investigated the performance of two separate building types, designed using ASCE 7-05, using the analysis procedures from ASCE 41-06. The results from the ASCE 41-06 analyses were compared to the expected performance level of Life Safety to determine the adequacy of the ASCE 7-05 design. ASCE 7-05 is intended to result in designs that perform to a Life Safety performance level regardless of the building type. A design using the AISC specifications for a steel Special Moment Frame and the lateral loads from ASCE 7-05 resulted in a building that slightly exceeded an Immediate Occupancy performance level for …

Tc17 Cd8 T Cells: Functional Plasticity And Subset Diversity, Adam J. Adler

UCHC Articles - Research

L-17-secreting CD8 T cells (Tc17) have been described in several settings, but little is known regarding their functional characteristics. While Tc1 cells produced IFN-γ and efficiently killed targets, Tc17 cells lacked lytic function in vitro. Interestingly, the small numbers of IFN-γ-positive or IL-17/IFN-γ-double-positive cells generated under Tc17 conditions also lacked lytic activity and expressed a similar pattern of cell surface proteins to IL-17-producing cells. As is the case for Th17 (CD4) cells, STAT3 is important for Tc17 polarization, both in vitro and in vivo. Adoptive transfer of highly purified, Ag-specific IL-17-secreting Tc17 cells into Ag-bearing hosts resulted in near complete …

The Pace Of Technology Transfer In Anticipation Of Joint Venture Breakup, Raphael Soubeyran, Ngo Van Long, Antoine Soubeyran

Fondazione Eni Enrico Mattei Working Papers

This paper studies the properties of joint-venture relationship between a technologically advanced multinational firm and a local firm operating in a developing economy where the ability to enforce contracts is weak. We formulate a dynamic model of principal-agent relationship in which at any point of time the local firm can quit without legal penalties. An early breakup may be prevented if the multinational designs a suitable scheme in which both the pace and aggregate amount of technology transfer deviate from the first-best, and a suitable flow of side payments to encourage the local firm to stay longer.

On The Real Effects Of Bank Bailouts: Micro-Evidence From Japan, Mariassunta Giannetti, Andrei Simonov

Fondazione Eni Enrico Mattei Working Papers

Exploiting the Japanese banking crisis as a laboratory, we provide firm-level evidence on the real effects of bank bailouts. Government recapitalizations result in positive abnormal returns for the clients of recapitalized banks. After recapitalizations, banks extend larger loans to their clients and some firms increase investment, but do not create more jobs than comparable firms. Most importantly, recapitalizations allow banks to extend larger loans to low and high quality firms alike, and low quality firms experience higher abnormal returns than other firms. Interestingly, recapitalizations by private investors have similar effects. Moreover, bank mergers engineered to enhance bank stability appear to …

On Neutral Absorption And Spectral Evolution In X-Ray Binaries, J. M. Miller, E. M. Cackett, R. C. Reis

Physics and Astronomy Faculty Research Publications

Current X-ray observatories make it possible to follow the evolution of transient and variable X-ray binaries across a broad range in luminosity and source behavior. In such studies, it can be unclear whether evolution in the low-energy portion of the spectrum should be attributed to evolution in the source, or instead to evolution in neutral photoelectric absorption. Dispersive spectrometers make it possible to address this problem. We have analyzed a small but diverse set of X-ray binaries observed with the Chandra High Energy Transmission Grating Spectrometer across a range in luminosity and different spectral states. The column density in individual …

Vitisnet: ‘‘Omics’’ Integration Through Grapevine Molecular Networks, Jerome Grimplet, Grant R. Cramer, Julie A. Dickerson, Kathy Mathiason, John Van Hemert, Anne Y. Fennell

Agronomy, Horticulture and Plant Science Faculty Publications

Background: Genomic data release for the grapevine has increased exponentially in the last five years. The Vitis vinifera genome has been sequenced and Vitis EST, transcriptomic, proteomic, and metabolomic tools and data sets continue to be developed. The next critical challenge is to provide biological meaning to this tremendous amount of data by annotating genes and integrating them within their biological context. We have developed and validated a system of Grapevine Molecular Networks (VitisNet).

Methodology/Principal Findings: The sequences from the Vitis vinifera (cv. Pinot Noir PN40024) genome sequencing project and ESTs from the Vitis genus have been paired and the …

Asian Maths Whizz And Talkative Females: How Stereotypes Can Actually Boost Performance, Knowledge@Smu

Knowledge@SMU

Nobody likes to be pigeonholed or reduced to a single stereotype. One reason could be because we believe ourselves to be products of multiple stereotypes: a combination of identities, such as "Asian", "female", "lawyer", "Gen X", "Christian", "Chinese", etc. While these labels connect us to like-individuals, they can also carry all sorts of connotations and expectations – positive, neutral and negative. For example, an Asian might be expected to outperform a non-Asian at mathematics because of stereotypes that Asians are mathematically inclined. Will such undue expectations affect the Asian's performance outcome? Research studies point to a 'Yes'.

The Impact Of Third Places On Community Quality Of Life, Leo Wayne Jeffres, Cheryl Campanella Bracken, Guowei Jian, Mary F. Casey

Communication Faculty Publications

Older cities struggling with issues of survival focus on jobs and the economy, but competition requires all cities to pay attention to the quality of life that attracts residents. Creating such an inviting environment includes “third places” that foster community and communication among people outside of home and work, yet we have little empirical evidence that speaks to the subject, or their importance for a community’s quality of life. Here we report on a national U.S. survey that asked people to identify such places in their community, producing a wide variety of “third places” that ranged from the most popular …
