- Description:
- Coalbed natural gas (CBNG) co-produced waters can contain sodium (Na+) concentrations that may be environmentally detrimental if discharged to receiving bodies of water or applied to land surfaces. A field demonstration and companion laboratory studies were conducted to evaluate the use of a Bear River zeolite (BR-zeolite) for mitigating impacts associated with Na+ in CBNG waters. Bench-scale kinetic and adsorption isotherm studies were performed to determine both the rate and extent of sodium Na+ adsorption and assess the effects of bicarbonate (HCO3-) and chloride (Cl-) anions. Results of these studies showed that the adsorption of Na+ on BR-zeolite followed the Langmuir adsorption model with maximum adsorption equal to 21 and 18 g Na+/kg zeolite with 0.0012 and 0.0006 L/mg Langmuir coefficients (KL) for sodium bicarbonate and sodium chloride, respectively. The kinetics study indicated that the sorption of Na+ was inversely related to the size of the zeolite particles with significantly greater adsorption for smaller particles. The field demonstration evaluated the effectiveness of BR-zeolite for mitigating infiltration losses from Na+ in CBNG waters. The field site utilized 12 open boreholes, each installed to a depth of approximately 1.8 m. Each borehole was lined with a 3.0 m long, 15 cm diameter schedule 40 PVC pipe and fitted with an automatic data logging pressure transducer for measuring water levels over time. The BR-zeolite was found to mitigate much of the deleterious effect that high sodium adsorption ratio (SAR = 27 (mol/m3)1/2) CBNG co-produced water had on soil permeabilities.

- Description:
- This study examines the differences in body mass index (BMI) and body perception between White and Hispanic female students attending California State University, Fresno. White and Hispanic/Latino cultures have differing ideals of body size. This study examines the impact diet, physical activity, and race has on BMI and body perception. This study utilizes secondary data from the 2007 National Collegiate Health Assessment, a Web-based survey administered to randomly selected CSU, Fresno students. Data regarding height, weight, diet, physical activity level, body perception and race will be used for purpose of this study. The benefits of this study are greater knowledge of differences in ethnicity with respect to BMI and body perception as well as the possibility to identify needed resources for students on the university campus. There is minimal risk associated with this study as students cannot be identified based on responses.

- Description:
- The Santa Clara Valley Health and Hospital System’s (SCVHHS) Babies Reaching Improved Development and Growth in their Environment (BRIDGE) program was developed in 2011 to optimize high risk infants' care transition from Neonatal Intensive Care Unit (NICU) to home. In addition to hospital discharge teaching and public health nursing efforts, NICU infants need further in home support given their medical vulnerability after discharge. The objectives of the SCVHHS BRIDGE program are to provide caregiver interventions to minimize home care errors after NICU discharge and to optimize health care access and utilization across the transition of care. SCVHHS NICU infants at risk for developmental delay, who met Department of Health and Human Services (DHHS) California Children’s Services (CCS) High Risk Infant Follow-up (HRIF) criteria, qualified for SCVHHS BRIDGE visits. From April of 2011 to January of 2015 Pediatric Nurse Practitioners (PNPs) met caregivers in the NICU, visited homes a minimum of two times after discharge, identified errors, educated caregivers, coordinated care, and facilitated in the resolution of the errors. Errors were defined as a deviation from prescribed plan of care upon discharge from the NICU or after an ambulatory care visit. Data were collected prospectively and Institutional Review Board (IRB) approved. Chi Square with Yates correction was used to assess for significance. Wilcoxon Rank Sum test was used to assess association between gestational age, length of stay, and birth weight in infants with and without errors. Wilcoxon Signed Rank test was used to assess for significance of error reduction across visits. PNPs monitored, educated and attenuated home care errors between home visits and caregivers over time. Collaborating with caregivers and health care providers in the inpatient, home, and outpatient environments, PNPs have the potential to decrease errors, improve health, reduce health care costs, and optimize growth and development for high risk infants.

- Description:
- This study was conducted to establish the measure of adequacy of the summer biology courses of the Fresno City Schools. The specific intent was to conduct a study that would measure the adequacy as objectively as possible. The data collected were analyzed in a critical manner but with constructive intentions. Conclusions and recommendations which appeared to be proper were presented. Whether or not the results of this study prove to be beneficial will depend upon the opinion of those in a position to consider them and to effectuate the necessary action in accordance with the results. This study, however, definitely will be an advantage to the writer of this paper in the teaching of biology courses in the future. This study served as a means of self-evaluation of past biology teaching. The cooperation of the summer biology teachers is recognized and greatly appreciated. It is hoped that the results of this study will be of some value to them. The guidance of Dr. Orrin D. Wardle, who generously advised during the course of a very busy summer session and while on vacation, also is acknowledged. Without this co-operation and necessary advice, this study would not have been possible.

- Description:
- Historical geography defined in its simplest terms is concerned with the past landscapes of a portion of the earth's surface. Therefore, the purpose of this study will be to recreate the past landscapes of the three distinct periods--open range, homestead and present--for the Kansas Settlement in Sulphur Springs Valley. This will be accomplished by examining the successive patterns of human habitation and identifying the events that caused these patterns to change. The evaluation of settlement patterns and land use produced during each of these periods will indicate the relative importance of causal factors (e.g., political, economic and natural) in the generation of landscape change in the Sulphur Springs Valley of southeastern Arizona. The eve of the open range era was selected as a starting point for this study since before that time the landscape of the Sulphur Springs Valley was only slightly affected by man. However, events prior to the beginning of this era were important because they explain why the cattlemen eventually ventured into and prospered within the valley. Furthermore, the physical environment of this semiarid region has an impact upon certain human activities and thus is also important for this inquiry into landscape change. Therefore, the physical geography of the Sulphur Springs Valley and the historical background of the area will be considered before examining each of the three successive and distinct stages which have evolved and thus produced landscape changes in the Kansas Settlement.

- Description:
- One of the most important concerns of physical educator’s in our public schools should be that students develop positive attitudes towards active participation in physically wholesome activities. This will tend to lead them to seek similarly valuable physical activity after leaving organized school programs. Drink water has indicated that attitudes are not rigid, unyielding elements of the personality, but that they can be changed through experience and knowledge. The most significant factors fostering the development of coeducation in physical education are the natural interests of men and women in associating with one another in social activities and the increased emphasis in physical education upon social development. Coeducational physical education might not solve the problem completely, but it would appear to be a progressive step forward. In some junior and senior high schools, boys and girls already have coeducational physical education classes. Moreover, Voltmer and Eslinger have suggested that valuable lessons can be learned from coeducational physical education. The purpose of this study, therefore, was to measure whether coeducational experiences change attitudes toward physical education.
