Equation of state of quark-nuclear matter

Quark-nuclear matter (QNM) is a many-body system containing hadrons and deconfined quarks. Starting from a microscopic quark-meson coupling (QMC) Hamiltonian with a density dependent quark-quark interaction, an effective quark-hadron Hamiltonian is constructed via a mapping procedure. The mapping is implemented with a unitary operator such that composites are redescribed by elementary-particle field operators that satisfy canonical commutation relations in an extended Fock space. Application of the unitary operator to the microscopic Hamiltonian leads to effective, hermitian operators that have a clear physical interpretation. At sufficiently high densities, the effective Hamiltonian contains interactions that lead to quark deconfinement. The equation of state of QNM is obtained using standard many-body techniques with the effective quark-hadron Hamiltonian. At low densities, the model is equivalent to a QMC model with confined quarks. Beyond a critical density, when quarks start to deconfine, the equation of state predicted for QNM is softer than the QMC equation of state with confined quarks.Comment: 10 pages, ws-procs9x6.cls (included), 2 eps figures, to appear in the Proceedings of the Joint CSSM/JHF Workshop, Adelaide, March 14-21, 200

HUMAN NEEDS OF EMPLOYEES OF SELECTED GOVERNMENT FINANCIAL INSTITUTIONS

This study assessed the human needs of employees in selected government financial institutions. Human needs were categorized into three areas such as existence needs, relatedness needs, and growth needs. Using a descriptive-quantitative approach, data were gathered through a researcher-made questionnaire. The survey was conducted among randomly selected employees of four (4) Government Financial Institutions (GFIs)human needs, government financial institutions, compensation

Vasotocin receptor expression in the brain and pituitary gland during the ovulatory cycle of the fowl

Vasotocin receptors are members of seven transmembrane spanning G-protein associated receptors. Several isoforms have been recognized in mammals and birds. It has been shown that VT-1 expression occurs primarily in the brain while VT-2 expression occurs mainly in the pituitary. There is no current evidence to support that both VTR-1 and -2 are found in a single tissue. Our goal in this experiment was to see if VT-1 and VT-2 receptor mRNA expression varied in known sites of expression over the period of the ovulatory cycle of broiler breeder hens. In order to study potential changes in VT-1 and VT-2 expression, birds were sacrificed at 3 hour intervals over a 24 hour period. Blood samples were drawn. After cervical dislocation, the brain, pituitary, shell gland, and kidney were removed. Plasma was stored at -20ºC prior to determination of corticosterone levels by radioimmuno assays. Isolated mRNA from the brains and the pituitaries was transferred to nylon membranes for northern slot blot analysis. cDNA for VT-1 and VT-2 was used to make random primed cDNA probes. Corticosterone levels significantly increased at 9 hours post oviposition relative to all other times. Neither VT-1 or VT- 2 expression showed any significant variation over the 24 hour cycle. Based on these results, we conclude that VT-1 and VT-2 steady state mRNA levels do not fluctuate dramatically over the ovulatory cycle of broiler breeder hens. Further work on membrane bound receptors and on circadian variations in membrane bound receptors in the brain and pituitary is currently underway of broiler breeder hens

STEAM Inspired by Insight

Innovators of the 21st century might come from unexpected places. Visual impairment is no barrier when technology and creativity intersect. The world needs blind innovators! The blind input data without visual association and download blueprints of their surroundings to format a mental database. They categorize patterns, textures, and conditions to perceive their location in space. They are able to capture the beauty of the world through poetry and predict future trends through past experience – all without visual access to the physical world they inhabit.

“Creating a New Mythos”: Reassessing Race Standards and Latina/o Students

This research will focus on the race and ethnicity categories used to classify people in the United States in relation to school age students. The Office of Management and Budget (OMB) first standardized federal race and ethnicity categories in 1977 in order to enforce compliance with civil rights laws. In 1997 revisions were made to these standards due to increasing criticism by the public, advocacy groups, and government agencies (Williams, 2006). The 1977 decision by the OMB designated the category of Hispanic, or Latino, as an ethnicity rather than a race which was once again upheld in the 1997 update. The U.S. Census Bureau complied with these changes with each decennial questionnaire released thereafter and by the 2010-2011 school year the U.S. Department of Education (DOE) required all schools to do the same. The OMB\u27s admission that these categories are of no scientific or biological backing brings to question their ability to speak to the lived experience of people in the U.S. Additionally research shows that since the United States began counting its population, race categories were frequently altered with each census in order to exclude some members of society from opportunities based on their identity. Given this burdensome legacy the question arises-- does a variation in measurement policy, of the race definitions outlined by the Office of Management and Budgets, change the number of students identified under each race within the U.S. Department of Education and U.S. Census Bureau? Using Census 2010 data of people identified younger than the age of 18 and U.S. Department of Education (DOE) data, this research will attempt to understand how designating people that racially identify as Latino into their own category has the ability to change the total count of those belonging to other races

BIM: a technology acceptance model in Peru

The purpose of this paper is to empirically study factors that facilitate the adoption of building information modelling (BIM) among practitioners using the unified theory of technology acceptance model (TAM). The factors identified in the TAM were examined using a quantitative approach. The empirical investigation has been conducted using a survey questionnaire. The data set has been obtained from 73 architects and engineers in Peru. Results show that Perceived Usefulness (PU) is the most important determinant of Behavioural Intention (BI), while Perceived Ease of Use (PEOU) is found to have no significant effect on BI. The findings provide an excellent backdrop in the development of policy and a roadmap for BIM implementation in Peru. The original contribution and value of the paper is the use of TAM to provide empirical evidence on factors that facilitate BIM adoption in Peru
