Ultraviolet Light As An Adjunct Treatment To Pasteurization For Microbial Reduction In Milk Intended For Extended Shelf Life, Jacob Zonneveld

Dairy Science

The objective of this study was to determine whether ultraviolet light treatment of milk could be used in adjunct with pasteurization and to determine whether the microbial count in bulk tank raw milk was sufficient enough to receive significant results. Samples were collected from a bulk tank filled with 1600 gallons of raw Holstein and Jersey milk from the Cal Poly Dairy throughout the course of a week. Control (library) samples were also taken from the raw milk tank and stored without air or agitation for comparison. These samples were plated each day and examined 24 and 48 hours after …

Use Of An Activity Monitoring System As Part Of The Cal Poly Dairy Breeding Protocol, Trevor Nutcher

Dairy Science

The objective of this study, is to determine the effectiveness of an activity monitoring system as an integral part of the Cal Poly Dairy breeding protocol. Dairy herd reproductive efficiencies have dropped in the past 40 years. Increased milk production, and genetic advancements towards more milk production, have led to reproductive rates declining. An advanced breeding program is needed to become more efficient in this area. The study consisted of the evaluation of one option, Heatime™ by MICRO Dairy Logic, and comparing it to the commonly used programs in dairies today such as synchronization methods, pedometers, and other electronic detection …

Methane Digesters, Thomas Van Steyn

Dairy Science

Anaerobic digestion has many different avenues for opportunity in use on farms. The objective of my senior project is to determine the economic viability of alternative methane digesters on a dairy. Currently the conversion of animal manure to biogas through the process of anaerobic digestion is widely used in Europe. In the U.S. anaerobic digesters have become increasingly in demand by environmental groups and dairymen. Digesters environmental impact involves the benefit by capturing the biogas that comes off animal manure. Methane, a green house gas, is the one with the most concern that is captured by methane digesters. The biogas …

Like Mother Like Child: An Investigation Of Mother Characteristics And Child Temperaments, Tempus Fugitt

Statistics

Much research has gone into what biological and social factors raise the risk of children developing cognitive, social, or behavioral problems. This project looks at what characteristics of the mother are significantly associated with different temperaments in the child which may predict problems developed in the child later in life. These characteristics include mother’s age, her education level, household income, parenting attitudes, involvement with the child, and drug and alcohol use. Data was used from the Fragile Families and Child Wellbeing Study conducted by the Office of Population Research at Princeton University. Cumulative logistic regression was used to analyze the …

Investigating Wood Welding Parameters Using A Prototype Welding Machine, Timothy R. Melin

Master's Theses

Understanding how different processing variables influence wood welded bonds is vital if the technique will ever be used to create engineered lumber without using adhesives. A variation of vibration welding, wood welding uses pressure and friction to bond materials together. During welding, heat causes a softening in the wood, a naturally occurring composite material. This softening leads to fiber entanglement and a bond forms upon cooling.

The goal of this research was to investigate several processing aspects of the wood welding procedure. A prototype wood welding machine, designed and fabricated from the ground up, was used to investigate the effects …

Effect Of Sodium Chloride Addition During Diafiltration On The Solubility Of Milk Protein Concentrate, Scott J. Gualco

Master's Theses

There is considerable interest among food manufacturers to incorporate protein into food products in both developed and developing countries. Dairy proteins are excellent choices for many different applications, as they are known to have several nutritional and functional benefits. Membrane filtration techniques are often utilized as the preferred method of fractionation, due to the high throughput and continuous nature of the process. One such product produced from membrane filtration of skim milk is called milk protein concentrate. This product is valued for its high protein content, but it has historically exhibited poor solubility when reconstituted into water, which severely restricts …

Source Attribution Of Ozone In Southeast Texas Before And After The Deepwater Horizon Accident Using Satellite, Sonde, Surface Monitor, And Air Mass Trajectory Data, Gary A. Morris, Barry Lefer, Bernhard Rappenglueck, Christine Haman, Marc Taylor, Mark R. Schoeberl

Physics and Astronomy Faculty Presentations

Since the summer of 2004, over 300 ozonesondes have been launched from Rice University (29.7 N, 95.4 W) or the University of Houston (29.7 N, 95.3 W), each < 5 km from downtown Houston. The Texas Commission on Environmental Quality maintains a large database of hourly surface ozone observations in Southeast Texas. In this study, we identify the contributions to surface ozone pollution levels from natural and anthropogenic sources, both local and remote in nature. This source identification is performed two ways: 1) through an analysis of sonde data, including ozone concentrations, wind speed and direction, and relative humidity data, and 2) through an analysis that combines trajectory calculations with surface monitor data. We also examine regional changes in Ozone Monitoring Instrument (OMI) measurements of formaldehyde and ozone from 2004 – 2010. In particular, we compare the 2010 sonde, surface monitor, and satellite data after the Deepwater Horizon accident with data from previous years to determine the impact, if any, of the large source of hydrocarbons in the Gulf of Mexico on air quality in Southeast Texas.

The Human Population Growth And Its Ecological Consequences On Kenya And Tanzania, Lauren Noll

Student Theses 2001-2013

The world population is growing at an alarming rate. The rapid growth in population numbers and density along with the steady increase in the rates are causing issues in many countries. Although every country is experiencing many consequences of the growth, the countries of Kenya and Tanzania in East Africa seem to be suffering immensely. Not only does the increasing human population in these third world countries create an overarching competition for natural resources such as food, water, and land, the growth also has detrimental effects on the surrounding environment, wildlife populations, ecotourism, and traditional African cultures.

First Kepler Results On Compact Pulsators - Ii. Kic-010139564, A New Pulsating Subdwarf B (V361 Hya) Star With An Additional Low-Frequency Mode, S. D. Kawaler, Michael D. Reed, A. C. Quint, R. H. Østensen, R. Silvotti, A. S. Baran, S. Charpinet, S. Bloemen, D. W. Kurtz, For Complete List Of Authors, See Publisher's Website.

College of Natural and Applied Sciences

We present the discovery of non-radial pulsations in a hot subdwarf B star based on 30.5 d of nearly continuous time series photometry using the Kepler spacecraft. KIC-010139564 is found to be a short-period pulsator of the V361-Hya (EC-14026) class with more than 10 independent pulsation modes whose periods range from 130 to 190 s. It also shows one periodicity at a period of 3165 s. If this periodicity is a high-order g-mode, then this star may be the hottest member of the hybrid DW-Lyn stars. In addition to the resolved pulsation frequencies, additional periodic variations in the light curve …

First Kepler Results On Compact Pulsators - V. Slowly Pulsating Subdwarf B Stars In Short-Period Binaries, S. D. Kawaler, Michael D. Reed, R. H. Østensen, S. Bloemen, D. W. Kurtz, A. C. Quint, R. Silvotti, A. S. Baran, E. M. Green, For Complete List Of Authors, See Publisher's Website.

College of Natural and Applied Sciences

The survey phase of the Kepler Mission includes a number of hot subdwarf B (sdB) stars to search for non-radial pulsations. We present our analysis of two sdB stars that are found to be g-mode pulsators of the V1093-Her class. These two stars also display the distinct irradiation effect typical of sdB stars with a close M-dwarf companion with orbital periods of less than half a day. Because the orbital period is so short, the stars should be in synchronous rotation, and if so, the rotation period should imprint itself on the multiplet structure of the pulsations. However, we do …

First Kepler Results On Compact Pulsators - Iii. Subdwarf B Stars With V1093 Her And Hybrid (Dw Lyn) Type Pulsations, M. D. Reed, S. D. Kawaler, R. H. Østensen, S. Bloemen, A. Baran, J. H. Telting, R. Silvotti, S. Charpinet, A. C. Quint, For Complete List Of Authors, See Publisher's Website.

College of Natural and Applied Sciences

We present the discovery of non-radial pulsations in five hot subdwarf B (sdB) stars based on 27-d of nearly continuous time series photometry using the Kepler spacecraft. We find that every sdB star cooler than ≈27-500-K that Kepler has observed (seven so far) is a long-period pulsator of the V1093 Her (PG 1716) class or a hybrid star with both short and long periods. The apparently non-binary long-period and hybrid pulsators are described here. The V1093 Her periods range from 1 to 4.5-h and are associated with g-mode pulsations. Three stars also exhibit short periods indicative of p-modes with periods …
