African Journal of Food, Agriculture, Nutrition and Development , 2009,
Abstract: This experiment investigated the antinutrients content and functional properties of the seeds of African black pear (Dacryodes edulis). The study derived its importance from the environmental problem posed by the seeds of this highly cherished fruit. The aim of the project was to determine through empirical means the possible recycling potential that might be inherent in the seeds of the African black pear. Three seed varieties of the same sample categorized as Small (S), Medium (M) and Large (L) were used for this study. Standard experimental protocols were employed in the estimation of all indices. Data obtained indicate that the seed samples contained phytic acid: 12.13 + 1.14; 12.37 + 1.82 and 13.37 + 0.65g/100g sample on dry matter basis (DMB), respectively for Small, Medium and Large. Trypsin inhibitory activities (TIA) were determined as 546.67 + 30.55; 520.00 + 20.00; and 473.33 + 23.10g/100g sample on DMB in the same order, respectively. High amounts of oxalate 0.24 + 0.02 g-1100g for Small; 0.35 + 0.03 g-1100g for Medium and 0.37 + 0.03 g-1100g for Large while tannins were also found to be (5.07 + 0.14; 5.16 + 0.08; 5.02 + 0.16)g- 1100g for Small; Medium; and Large, respectively in the seeds. Water and oil absorption capacity as well as foam capacity and bulk density for all the samples did not differ significantly (P>0.05). The Medium seed flour, however, showed significantly (P<0.05) higher values in emulsion activity (40.82 + 1.52)% and foam stability (6.20 + 0.33)% as compared to foam stability of the Large seed (5.80 + 0.08)% variety. It may, therefore, be concluded from the strength of this novel results, that the seeds of Dacryodes edulis contained high amounts of phytic acid, oxalate, TIA and tannins. Physicochemical data on the other hand suggest the seeds of Dacryodes edulis to have valuable functional attributes of industrial interest.

Theories of schizophrenia: a genetic-inflammatory-vascular synthesis
Daniel R Hanson, Irving I Gottesman
BMC Medical Genetics , 2005, DOI: 10.1186/1471-2350-6-7
Abstract: A vascular component to a theory of schizophrenia posits that the physiologic abnormalities leading to illness involve disruption of the exquisitely precise regulation of the delivery of energy and oxygen required for normal brain function. The theory further proposes that abnormalities of CNS metabolism arise because genetically modulated inflammatory reactions damage the microvascular system of the brain in reaction to environmental agents, including infections, hypoxia, and physical trauma. Damage may accumulate with repeated exposure to triggering agents resulting in exacerbation and deterioration, or healing with their removal.There are clear examples of genetic polymorphisms in inflammatory regulators leading to exaggerated inflammatory responses. There is also ample evidence that inflammatory vascular disease of the brain can lead to psychosis, often waxing and waning, and exhibiting a fluctuating course, as seen in schizophrenia. Disturbances of CNS blood flow have repeatedly been observed in people with schizophrenia using old and new technologies. To account for the myriad of behavioral and other curious findings in schizophrenia such as minor physical anomalies, or reported decreased rates of rheumatoid arthritis and highly visible nail fold capillaries, we would have to evoke a process that is systemic such as the vascular and immune/inflammatory systems.A vascular-inflammatory theory of schizophrenia brings together environmental and genetic factors in a way that can explain the diversity of symptoms and outcomes observed. If these ideas are confirmed, they would lead in new directions for treatments or preventions by avoiding inducers of inflammation or by way of inflammatory modulating agents, thus preventing exaggerated inflammation and consequent triggering of a psychotic episode in genetically predisposed persons.When the solution to a clinical or scientific puzzle eludes us for more than a century, as with schizophrenia (formerly dementia praecox)
Learning about Vegetarian Diets in School: Curricular Representations of Food and Nutrients in Elementary Health Education  [PDF]
Clara Hanson
Advances in Applied Sociology (AASoci) , 2012, DOI: 10.4236/aasoci.2012.21010
Abstract: This paper examines the way non-meat and plant based diets are discussed in four elementary curricula. The author used an open coding technique of grounded theory to understand the way food, nutrition and vegetarianism was discussed. The curricula relied heavily upon the USDA Food Pyramid and a related concept of “balance” for nutritional information. The curricula also discussed nutrition in terms of food and food groups, rather than in terms of nutrients. Although some of the curricula included information about the benefits of vegetarian diets, the high level of use of the Food Pyramid often overwhelmed the low level of information about vegetarianism.
Green's Function Expansions in Dyadic Root Functions for Shielded Layered Waveguides
G. W. Hanson;A. I. Nosich;E. M. Kartchevski
PIER , 2003, DOI: 10.2528/PIER02082205
Abstract: Dyadic Green's functions for inhomogeneous parallel-plate waveguides are considered. The usual residue series form of the Green's function is examined in the case of modal degeneracies, where secondorder poles are encountered. The corresponding second-order residue contributions are properly interpreted as representing "associated functions" of the structure by constructing a new dyadic root function representation of the Hertzian potential Green's dyadic. The dyadic root functions include both eigenfunctions (corresponding to first-order residues) and associated functions, analogous to the idea of Jordan chains in finite-dimensional spaces. Numerical results are presented for the case of a two-layer parallel-plate waveguide.

Trends in U.S. Voting Attitudes with a Consideration of Variation by Gender and Race/Ethnicity  [PDF]
Sandra L. Hanson
Open Journal of Political Science (OJPS) , 2016, DOI: 10.4236/ojps.2016.64038
Abstract: Low turnout rates and discussions of disaffected voters are receiving considerable attention as we approach the 2016 U.S. presidential elections. Do trends in American’s attitudes about voting and correlates of these attitudes (political involvement, efficacy, and social connectedness) confirm the pessimistic assessments and do voters across gender and race/ethnic groups think similarly? Data from the American National Election Studies (ANES) provide some reason for optimism. Trends over the past few presidential election periods show a majority of Americans intend to vote and this majority is increasing. Trends show increases or stability on numerous correlates of voting attitudes including political involvement and social connectedness. Trends in voting attitudes by gender and race/ethnicity show considerable variation. Women and race/ethnic minorities (especially African Americans) are an important element of the positive trends shown here. Findings on external efficacy are an exception to the generally optimistic trends with data showing a majority of respondents don’t believe public officials care what people like the respondent think. However, trends do not show an increase in negative attitudes about public officials. Implications of the findings are considered.

Abstract: Background The clinical results of removal of metal implants after fracture healing are unknown and the question whether to remove or to leave them in is part of discussion worldwide. We present the design of a prospective clinical multicentre cohort study to determine the main indications for and expectations of implant removal, the influence on complaints, the incidence of surgery related complications and the socio-economic consequences of implant removal. Methods/Design In a prospective multicentre clinical cohort study at least 200 patients with a healed fracture after osteosynthesis with a metal implant are included for analyzing the outcome after removal. Six hospitals in the Netherlands are participating. Special questionnaires are designed. The follow up after surgery will be at least six months. The primary endpoint is the incidence of surgery related complications. Secondary endpoints are the influence of removal on preoperative symptoms and complaints and the socio-economic consequences. Discussion By performing this study we hope to find profound arguments to remove or not to remove metal implants after fracture healing that can help to develop clear guidelines for daily practice.

Physics , 2000, DOI: 10.1086/301410
Abstract: We present a revised catalog of 2106 Galactic stars, selected without kinematic bias, and with available radial velocities, distance estimates, and metal abundances in the range 0.0 <= [Fe/H] <= -4.0. This update of the Beers and Sommer-Larsen (1995) catalog includes newly-derived homogeneous photometric distance estimates, revised radial velocities for a number of stars with recently obtained high-resolution spectra, and refined metallicities for stars originally identified in the HK objective-prism survey (which account for nearly half of the catalog) based on a recent re-calibration. A subset of 1258 stars in this catalog have available proper motions, based on measurements obtained with the Hipparcos astrometry satellite, or taken from the updated Astrographic Catalogue (AC 2000; second epoch positions from either the Hubble Space Telescope Guide Star Catalog or the Tycho Catalogue), the Yale/San Juan Southern Proper Motion (SPM) Catalog 2.0, and the Lick Northern Proper Motion (NPM1) Catalog. Our present catalog includes 388 RR Lyrae variables (182 of which are newly added), 38 variables of other types, and 1680 non-variables, with distances in the range 0.1 to 40 kpc.
