S.A.C. Lookout, Volume 3, Number 5, November 1898

In 1896, the students of the Storrs Agricultural College established a student newspaper, The Lookout. Published every month, The Lookout had a small, unpaid staff who laid out the pages by hand using tiny metal slugs with embossed letters from a printer\u27s California job case. By 1914, the paper had changed its name to The Connecticut Campus, reflecting the growth of the institution that had become the Connecticut Agricultural College in 1899 and the student newspaper increased its publication schedule to twice a month. The paper continued to grow along with the campus in Storrs, CT, and in 1953 the The Connecticut Campus, which had moved from being published monthly, to weekly and then to a three days a week publication schedule made its last transition to becoming a daily newspaper. In 1955, the renamed Connecticut Daily Campus becomes a morning paper that is printed on newsprint. In the 1970s, the University of Connecticut Board of Trustees granted the Connecticut Daily Campus its independence from the Associated Student Government. Currently, Daily Campus is the largest daily college newspaper in the state of Connecticut and employs more than 120 students during the academic year. Published Monday through Friday during the academic year, 10,000 copies are delivered to over 80 locations both on- and off-campus

Test of Information Theory on the Boltzmann Equation

We examine information theory using the steady-state Boltzmann equation. In a nonequilibrium steady-state system under steady heat conduction, the thermodynamic quantities from information theory are calculated and compared with those from the steady-state Boltzmann equation. We have found that information theory is inconsistent with the steady-state Boltzmann equation.Comment: 12 page

Shock tunnel studies of scramjet phenomena, supplement 6

Reports by the staff of the University of Queensland on various research studies related to the advancement of scramjet technology are presented. These reports document the tests conducted in the reflected shock tunnel T4 and supporting research facilities that have been used to study the injection, mixing, and combustion of hydrogen fuel in generic scramjets at flow conditions typical of hypersonic flight. In addition, topics include the development of instrumentation and measurement technology, such as combustor wall shear and stream composition in pulse facilities, and numerical studies and analyses of the scramjet combustor process and the test facility operation

Comparison of Transcript Profiles in Wild-Type and o2 Maize Endosperm in Different Genetic Backgrounds

Mutations in the Opaque2 (O2) gene of maize (Zea mays L.) improve the nutritional value of maize by reducing the level of zeins in the kernel. The phenotype of o2 grain is controlled by many modifier genes and is therefore strongly dependent on genetic background. We propose two hypotheses to explain differences in phenotypic severity in different genetic backgrounds: (i) Specific genes are differentially (o2 vs. wild-type) expressed only in certain genotypes, and (ii) A set of genes are differentially expressed in all backgrounds, but the degree of differential expression differs in different backgrounds. To determine the extent to which these two hypotheses contribute to determining the severity of o2 in different genetic backgrounds, we identified transcripts likely to be differentially expressed in several genetic backgrounds by transcript profile comparison of endosperm RNA pools from eight o2 inbred lines and their wild-type counterparts. The inbred line B46 was identified as having severe o2 phenotypes while the line M14 was identified as having minimal o2 phenotypes. The degree of wild-type vs. o2 differential expression of transcripts was determined for these two lines. We found that most genes that are downregulated by o2 tend to be differentially expressed to a greater degree in B46 than in M14, while upregulated genes tend to be more highly differentially expressed in one genetic background or the other. Thus, hypothesis one functions more prominently for upregulated genes while hypothesis two functions most prominently for downregulated genes

Some thoughts about nonequilibrium temperature

The main objective of this paper is to show that, within the present framework of the kinetic theoretical approach to irreversible thermodynamics, there is no evidence that provides a basis to modify the ordinary Fourier equation relating the heat flux in a non-equilibrium steady state to the gradient of the local equilibrium temperature. This fact is supported, among other arguments, through the kinetic foundations of generalized hydrodynamics. Some attempts have been recently proposed asserting that, in the presence of non-linearities of the state variables, such a temperature should be replaced by the non-equilibrium temperature as defined in Extended Irreversible Thermodynamics. In the approximations used for such a temperature there is so far no evidence that sustains this proposal.Comment: 13 pages, TeX, no figures, to appear in Mol. Phy

Junior doctors' experiences of managing patients with medically unexplained symptoms: a qualitative study

OBJECTIVES: To explore junior doctors' knowledge about and experiences of managing patients with medically unexplained symptoms (MUS) and to seek their recommendations for improved future training on this important topic about which they currently receive little education. DESIGN: Qualitative study using in-depth interviews analysed using the framework method. SETTING: Participants were recruited from three North Thames London hospitals within the UK. PARTICIPANTS: Twenty-two junior doctors undertaking the UK foundation two-year training programme (FY1/FY2). RESULTS: The junior doctors interviewed identified a significant gap in their training on the topic of MUS, particularly in relation to their awareness of the topic, the appropriate level of investigations, possible psychological comorbidities, the formulation of suitable explanations for patients' symptoms and longer term management strategies. Many junior doctors expressed feelings of anxiety, frustration and a self-perceived lack of competency in this area, and spoke of over-investigating patients or avoiding patient contact altogether due to the challenging nature of MUS and a difficulty in managing the accompanying uncertainty. They also identified the negative attitudes of some senior clinicians and potential role models towards patients with MUS as a factor contributing to their own attitudes and management choices. Most reported a need for more training during the foundation years, and recommended interactive case-based group discussions with a focus on providing meaningful explanations to patients for their symptoms. CONCLUSIONS: There is an urgent need to improve postgraduate training about the topics of MUS and avoiding over-investigation, as current training does not equip junior doctors with the necessary knowledge and skills to effectively and confidently manage patients in these areas. Training needs to focus on practical skill development to increase clinical knowledge in areas such as delivering suitable explanations, and to incorporate individual management strategies to help junior doctors tolerate the uncertainty associated with MUS

Evidence for a change in the nuclear mass surface with the discovery of the most neutron-rich nuclei with 17<Z <25

The results of measurements of the production of neutron-rich nuclei by the fragmentation of a 76-Ge beam are presented. The cross sections were measured for a large range of nuclei including fifteen new isotopes that are the most neutron-rich nuclides of the elements chlorine to manganese (50-Cl, 53-Ar, 55,56-K, 57,58-Ca, 59,60,61-Sc, 62,63-Ti, 65,66-V, 68-Cr, 70-Mn). The enhanced cross sections of several new nuclei relative to a simple thermal evaporation framework, previously shown to describe similar production cross sections, indicates that nuclei in the region around 62-Ti might be more stable than predicted by current mass models and could be an indication of a new island of inversion similar to that centered on 31-Na.Comment: 4 pages, 3 figures, to be published in Physical Review Letters, 200

Prevention of Mycobacterium avium Subspecies paratuberculosis (MAP) Infection in Balb/c mice by Feeding Lactobacillus acidophilus Strain NP-51®

The immune responses of 390 BALB/c mice fed the probiotic Lactobacillus acidophilus strain NP51 ® and infected with Mycobacterium avium subspecies paratuberculosis (MAP) were evaluated in a 6-month trial. Mice were randomized to nine treatment groups that fed either viable- or heat-killed NP51 and inoculated with either viable- or heatkilled MAP or sterile phosphate-buffered saline. Feeding the NP51 resulted in higher numbers of T lymphocytes in the spleen including the CD8 + cytotoxic T lymphocytes. In addition, feeding the NP51 lowered the number of immune suppressive T regulatory cells CD4 + CD25 + and CD8 + CD25 + cells in the spleen. Additionally, feeding the NP51 resulted in higher concentration of interferon-gamma in the supernatant of splenocytes cultured in vitro. These results suggest that feeding the NP51 to BALB/c mice might prevent the progression of MAP infection in mice
