Scalar Emission in the Bulk in a Rotating Black Hole Background
We study the emission of scalars into the bulk from a higher-dimensional
rotating black hole. We obtain an analytic solution to the field equation by
employing matching techniques on expressions valid in the near-horizon and
far-field regimes. Both analytic and numerical results for the absorption
probability, in the low-energy and low-angular momentum limit, are derived and
found to be in excellent agreement. We also compute the energy emission rate,
and show that the brane-to-bulk ratio of the energy emission rates for scalar
fields remains always larger than unity in the aforementioned regime.Comment: 14 pages, Latex file, 5 figures, references adde
Pathos: a web facility that uses metabolic maps to display experimental changes in metabolites identified by mass spectrometry
This work describes a freely available web-based facility which can be used to analyse raw or processed mass spectrometric data from metabolomics experiments and display the metabolites identified – and changes in their experimental abundance – in the context of the metabolic pathways in which they occur. The facility, Pathos (http://motif.gla.ac.uk/Pathos/), employs Java servlets and is underpinned by a relational database populated from the Kyoto Encyclopaedia of Genes and Genomes (KEGG). Input files can contain either raw m/z values from experiments conducted in different modes, or KEGG or MetaCyc IDs assigned by the user on the basis of the m/z values and other criteria. The textual output lists the KEGG pathways on an XHTML page according to the number of metabolites or potential metabolites that they contain. Filtering by organism is also available. For metabolic pathways of interest, the user is able to retrieve a pathway map with identified metabolites highlighted. A particular feature of Pathos is its ability to process relative quantification data for metabolites identified under different experimental conditions, and to present this in an easily comprehensible manner. Results are colour-coded according to the degree of experimental change, and bar charts of the results can be generated interactively from either the text listings or the pathway maps. The visual presentation of the output from Pathos is designed to allow the rapid identification of metabolic areas of potential interest, after which particular results may be examined in detail

Higher-dimensional black holes: Braneworld stars and Hawking radiation.
In this thesis two aspects of braneworld models are studied. A new attempt at finding the metric of a braneworld black hole within the second Randall-Sundrum model is explored. Branes containing distributions of perfect fluid are embedded in a variety of 5-dimensional 5O(4)-symmetric bulk spacetimes so that the Israel junction conditions are satisfied. A particular class of time-dependent embeddings are studied and shown to be unable to describe the braneworld black hole. Static trajectories are then investigated in five-dimensional anti-de Sitter and Schwarzschild backgrounds. These reveal a wide variety of permissible trajectories which are classified according to their energy-momentum profiles. The static embedding of branes in a Schwarzschild-anti-de Sitter spacetime is then explored, revealing objects with possible interpretation as "braneworld stars”. The evaporation of higher-dimensional rotating black holes, both on the brane and in the bulk is studied from an analytical perspective. A matching technique is employed to derive the solution for the radial component of the fields of scalars, fermions and gauge bosons propagating in the brane-induced line-element of a higher-dimensional rotating black hole. These solutions are used to calculate Hawking radiation spectra from a black hole in the spin-down phase of its lifetime within the Arkani-Hamed-Dimopoulos-Dvali model. The same method is used to calculate the emission of scalar fields into the bulk spacetime of a higher-dimensional rotating, black hole and a comparison is made between brane and bulk emission rates. Finally the matching technique is applied to the problem of graviton emission in the bulk from a higher-dimensional Schwarzschild black hole
Parental Engagement in the Baptismal Process at Florida Hospital Seventh-day Adventist Church
Problem
Baptism, one of the few spiritual milestones in the life of a young person, is not experienced at Florida Hospital Church with the intentional inclusion of parents, a group that has a greater spiritual influence for their children than any other person.
Method
To help engage parents in the process, a baptismal preparation program was developed that provided training and resources for parents who then prepared their children for baptism. The program consisted of a session with parents, children, and the pastor; two sessions with parents and the pastor; and four sessions done by parents in the home with their children. The program was intended to be done over a period of three weeks.
Results
Over a period of a year, three different groups met. They were comprised of 12 family units totaling 16 children. Based on the results of initial and final assessments, parents were more engaged in the spiritual development of their children and felt more positive about their own faith walk as a result of going through the program. Additionally, families reported a stronger faith walk, higher satisfaction with family worship, increased dialogue in spiritual topics outside of family worship, and a perceived increase in Bible knowledge, doctrinal knowledge, and prayer.
Conclusion
Parental engagement in the baptismal process grows the spiritual life of both parents and children. In a culture where young people are walking away from their faith due to a lack of familial engagement, this program could be used to continue the faith dialogue with parents, which studies indicate is a key factor in faith retention for young people. It is recommended that Florida Hospital Church use this program as the primary means for baptismal preparation for young people
The Truth About Your Monsters
The Truth About Your Monsters is an immersive and dialogical exhibition formatted as a walk-through storybook environment. Viewers are transported into a child’s make believe world through hands-on stations. By building on the skeleton of an archetypal narrative, audience members are encouraged to tap into their own experience as they contribute imagery and action to the narrative. I call on audience members to discuss personal or universal fears by prompting them to draw images of monsters that represent their fear
Brucella canis in Dogs
Brucella canis is a gram negative coccobacillus that was first isolated in 1966. It was first recognized in large breeding colonies of beagles, but subsequent independent investigators found many other breeds and mixed-breed dogs to be infected with the organism
