Support of EOR to independent producers in Texas: Quarterly report, 1 October 1994--30 January 1995
The general objective is to assist independent producers in Texas in applying tertiary recovery technology to their oil fields. The more specific objectives are: (1) identify production problems, and present technology to overcome such problems, (2) train independent producers how to select suitable EOR techniques and implement them, (3) conduct seminars and workshops on various EOR techniques and their applications, (4) train independent producers how to use available software in the fields of EOR operations, financing, and workover jobs, (5) establish a technology transfer center to lend primarily the independent producers in Texas the needed assistance to understand and use the state of the art technology data base in their operations. The kick-start of the project has focused on the following approaches (1) recruiting voluntary members to serve on an advisory committee for the project, (2) reaching out to possible organizations for data base information about independent producers of Texas, (3) reaching independent producers by different ways of communications, (4) conduct technical meeting with consultants, universities, and professional, (5) select topics of immediate concerns related independent producers operational problems, (6) establish a library or software resources for future use in workshops, (7) setting, future schedule for seminars and workshop to assist independent producers in understanding more about their field operations
Support of enhanced oil recovery to independent producers in Texas. Quarterly report, July 1, 1996--September 30, 1996
To establish a Technology Transfer Resource Center (TRC) at Prairie View A&M University (PVAMU) to assist the Independent Oil Producers, in the state of Texas, (TIP) obtain and apply oil recovery technology to their operation. The University will conduct a field pilot project in cooperation with an Independent Producer to demonstrate how technology application improves the economic performance of a project. Experience gained from the project will be disseminated to other Independents. These activities will be coordinated with neighboring state Universities and private research entities active in technology transfer programs. The University`s goal is to stimulate Petroleum Engineering education and research at the university as a result of participating in these activities. The long term goal is to establish the first Petroleum Engineering Department at a Historically Black University
Transcriptomic and metabolic responses of Calotropis procera to salt and drought stress
Background:
Calotropis procera is a wild plant species in the family Apocynaceae that is able to grow in harsh, arid and heat stressed conditions. Understanding how this highly adapted plant persists in harsh environments should inform future efforts to improve the hardiness of crop and forage plant species. To study the plant response to droμght and osmotic stress, we treated plants with polyethylene glycol and NaCl and carried out transcriptomic and metabolomics measurements across a time-course of five days.
Results:
We identified a highly dynamic transcriptional response across the time-course including dramatic changes in inositol signaling, stress response genes and cytokinins. The resulting metabolome changes also involved sharp increases of myo-inositol, a key signaling molecule and elevated amino acid metabolites at later times.
Conclusions:
The data generated here provide a first glimpse at the expressed genome of C. procera, a plant that is exceptionally well adapted to arid environments. We demonstrate, through transcriptome and metabolome analysis that myo-inositol signaling is strongly induced in response to drought and salt stress and that there is elevation of amino acid concentrations after prolonged osmotic stress. This work should lay the foundations of future studies in adaptation to arid environments
Analysis of transcriptional response to heat stress in Rhazya stricta
Clusters of assembled transcripts of R. stricta SRA in mature leaves (A5-L8) at different time points of the day (A, morning; F-H, midday & L, dusk). Grey lines indicate expression patterns of individual transcripts in a given cluster. Blue lines indicate overall expression pattern across different transcripts of a given cluster. (PDF 397 kb

Treatment of Infections in Young Infants in Low- and Middle-Income Countries:A Systematic Review and Meta-analysis of Frontline Health Worker Diagnosis and Antibiotic Access
BACKGROUND: Inadequate illness recognition and access to antibiotics contribute to high case fatality from infections in young infants (<2 months) in low- and middle-income countries (LMICs). We aimed to address three questions regarding access to treatment for young infant infections in LMICs: (1) Can frontline health workers accurately diagnose possible bacterial infection (pBI)?; (2) How available and affordable are antibiotics?; (3) How often are antibiotics procured without a prescription? METHODS AND FINDINGS: We searched PubMed, Embase, WHO/Health Action International (HAI), databases, service provision assessments (SPAs), Demographic and Health Surveys, Multiple Indicator Cluster Surveys, and grey literature with no date restriction until May 2014. Data were identified from 37 published studies, 46 HAI national surveys, and eight SPAs. For study question 1, meta-analysis showed that clinical sign-based algorithms predicted bacterial infection in young infants with high sensitivity (87%, 95% CI 82%-91%) and lower specificity (62%, 95% CI 48%-75%) (six studies, n = 14,254). Frontline health workers diagnosed pBI in young infants with an average sensitivity of 82% (95% CI 76%-88%) and specificity of 69% (95% CI 54%-83%) (eight studies, n = 11,857) compared to physicians. For question 2, first-line injectable agents (ampicillin, gentamicin, and penicillin) had low variable availability in first-level health facilities in Africa and South Asia. Oral amoxicillin and cotrimoxazole were widely available at low cost in most regions. For question 3, no studies on young infants were identified, however 25% of pediatric antibiotic purchases in LMICs were obtained without a prescription (11 studies, 95% CI 18%-34%), with lower rates among infants <1 year. Study limitations included potential selection bias and lack of neonatal-specific data. CONCLUSIONS: Trained frontline health workers may screen for pBI in young infants with relatively high sensitivity and lower specificity. Availability of first-line injectable antibiotics appears low in many health facilities in Africa and Asia. Improved data and advocacy are needed to increase the availability and appropriate utilization of antibiotics for young infant infections in LMICs.

Support of EOR to independent producers in Texas. Quarterly report, April 1995--June 1995
Extensive research has been conducted nationwide since the early 1970`s to increase our domestic oil production via Enhanced oil Recovery (EOR) technology. Less effort has been made to assure that state-of-the-art EOR technology reaches all producers, especially independents, so they can understand and use it to their benefit. Further, very little effort has been made to make EOR research results useful to the broadest possible base of producers. This report presents information on horizontal drilling and oil well planning including drilling tools, bottomhole assembly tools, drilling equipment, and well completion. A glossary of applicable terms and diagrams are included
