Abstract: Se estudiaron 40 pacientes del sexo femenino, premenopáusicas, menores de 45 a os, con diagnóstico establecido de artritis reumatoidea según criterios del Colegio Americano de Reumatología y todas con tratamiento de esteroides, con un equipo de densitometría ósea por ultrasonido del calcáneo. Al analizar el promedio de t-score (como marcador de osteoporosis), encontramos que el valor más bajo de fue de - 4,5 y el máximo de -1,5. Se empleó el test estadístico t -Student para comparar los promedio del t-score según: dosis, tiempo de tratamiento con esteroides y tiempo de evolución de la enfermedad. Se encontró osteoporosis en 23 pacientes que tomaban más de 20 mg de esteroides; en 27 con más de 5 a os de tratamiento con esteroides; y en 23 con más de 5 a os de evolución de la enfermedad. Al explorar el antecedente de fractura y relacionarlo con el tiempo de tratamiento y la dosis de esteroides encontramos que 9 pacientes (81,8 %) con más de 5 a os de tratamiento y 6 (54,5 %) con más de 20 mg de esteroides tienen antecedente de fractura. 40 premenopausic female patients under 45 with established diagnosis of rheumatoid athritis according to the criteria of the American College of Rheumatology were studied.

Abstract: Se estudió un grupo de 52 mujeres en etapa premenopáusica con diagnóstico de bocio tóxico difuso y un grupo control constituido por 54 mujeres sanas. Se encontró que la media para la edad en el grupo 1 fue de 35,7 a os y para el grupo 2, de 34,83 y la media en las 106 pacientes fue de 35,29 a os. Se midió la densidad mineral ósea mediante un equipo de densitometría ósea por ultrasonido del calcáneo (SONOST 2000 Medison). Se evidenció que el número de casos sin alteración ósea fue mayor en el grupo control: 40 casos (74,0 %), contra 8 (15,4 %) del grupo 1, y este grupo tuvo el mayor porcentaje de casos con osteopenia (22 [42,3 %]) y osteoporosis (22 [42,3 %]). Al utilizar estudios no paramétricos como el test de Rangos con signos de Wilcoxon encontramos que existe diferencia significativa entre el estudio inicial y el final, según los resultados de la osteosonometría. La osteosonometría fue normal al a o del tratamiento en 19 pacientes por encima de la realizada inicialmente, y la osteoporosis desapareció en 10 pacientes. Se halló que los 16 que se mantuvieron hipertiroideos al realizarle el estudio final de osteosonometría, presentaban osteopenia u osteoporosis. Mientras que en los 25 pacientes eutiroideos la osteosonometría fue normal. Al final, 27 sujetos tuvieron un resultado en la osteosonometría en el rango normal, 19 por encima del estudio inicial. En los sujetos a los que se les aplicó el esquema de tratamiento 3, en 15 la osteosonometría fue normal, así como que fue el grupo que menos pacientes osteoporóticos tuvo, con 2 solamente, aunque con el tratamiento 2 la respuesta fue bastante adecuada, no así con el tratamiento 1 2 women in premenopausal stage diagnosed as diffuse toxic goiter and a control group including 54 healthy women were studied.

Extending Multi-Period Pluto and Tasche PD Calibration Model Using Mode LRDF Approach  [PDF]
Denis Surzhko
Journal of Mathematical Finance (JMF) , 2014, DOI: 10.4236/jmf.2014.44026
Abstract:
The intention of this paper is to propose extension to the Pluto and Tasche PD calibration model for low default portfolios that could produce more stable LRDF estimates and eliminate the necessity of quartile choice, while preserving adequate level of conservatism. Multi-period Pluto and Tasche model allows us to fulfill Basel committee requirements regarding long-term LRDF calibration even for portfolios with no observable defaults. The main drawback of that approach is a very strict requirement for the sample: only borrowers that are observable to the bank within each point on long-term horizon could be used as observations. Information regarding rating migrations, borrowers that arrived in the portfolio after sample cutoff date and borrowers that left the portfolio before the end of long-term calibration horizon should be excluded from the sample. Proposed Mode approach pairs Pluto and Tasche model with mode LRDF estimator (proposed by Canadian OSFI), as the results, it eliminates drawbacks of the original Pluto and Tasche model.
Geospatial Analysis of Geotechnical Data Applied to Urban Infrastructure Planning  [PDF]
Rodolfo Moreda MENDES, Reinaldo LORANDI
Journal of Geographic Information System (JGIS) , 2010, DOI: 10.4236/jgis.2010.21006
Abstract: The urbanization process inside the State of São Paulo (Brazil) facilitated, in approximately five decades, the migration of thousands of peasants to the urban areas of great industrial centers inducing and requesting, at the same time and very often, an amplification of the systems of local urban infrastructure not appropriate for the natural potential of the physical territory. In this content, the city of São José do Rio Preto (State of São Paulo) with little more than 350.000 inhabitants, currently faces serious problems related to the urban planning originating from the unusual occupation and without previous study of suitability. Therefore, the present paper intends to guide and indicate the areas whose potential of urban development leads to an occupation suitable for the construction of shallow foundations in residential buildings of single floor, using an interpretative chart produced by the software GIS-SPRING-4.0 developed by Instituto Nacional de Pesquisas Espaciais/INPE (Brazil), and based in the methodology of geotechnical mapping developed by the department of geotechnical engineering of EESC/USP (Brazil). The chart for shallow foundation shows that a large portion of the studied area presents serious relationship problems with layers of highly collapsible soils.
Generalization of the Second Order Vector Potential Formulation for Arbitrary Non-Orthogonal Curvilinear Coordinates Systems from the Covariant Form of Maxwell's Equations  [PDF]
Denis Prémel
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2012, DOI: 10.4236/jemaa.2012.410055
Abstract: A great number of semi-analytical models, notably the representation of electromagnetic fields by integral equations are based on the second order vector potential (SOVP) formalism which introduces two scalar potentials in order to obtain analytical expressions of the electromagnetic fields from the two potentials. However, the scalar decomposition is often known for canonical coordinate systems. This paper aims in introducing a specific SOVP formulation dedicated to arbitrary non-orthogonal curvilinear coordinates systems. The electromagnetic field representation which is derived in this paper constitutes the key stone for the development of semi-analytical models for solving some eddy currents moelling problems and electromagnetic radiation problems considering at least two homogeneous media separated by a rough interface. This SOVP formulation is derived from the tensor formalism and Maxwell’s equations written in a non-orthogonal coordinates system adapted to a surface characterized by a 2D arbitrary aperiodic profile.
A paradigm for a skin graft substitute  [PDF]
Denis E. Solomon
Open Journal of Regenerative Medicine (OJRM) , 2013, DOI: 10.4236/ojrm.2013.22005
Abstract:

Skin grafts have remained relatively unchanged since their introduction as a medical treatment for burns/wounds. This paper seeks to open an academic discussion as to whether their use-by date has now been passed. A skin graft substitute is described in a paradigm using fine leaf gelatine sheets which inherently possess several distinct advantages including, discarding the harvest of autologous tissue from patient donor sites. A clinical study will be needed to determine its suitability taken together with the understanding that experimental animal studies may not provide unequivocal answers to its in situ modus operandi.

Interpretivistic Conception of Quantification: Tool for Enhancing Quality of Life?  [PDF]
Denis Larrivee, Adriana Gini
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.34A003
Abstract: Quality of life is fast becoming the standard measure of outcome in clinical trials, residential satisfaction, and educational achievement, to name several social settings, with the consequent proliferation of assessment instruments. Yet its interpretation and definition provoke widespread disagreement, thereby rendering the significance of quantification uncertain. Moreover, quality, or qualia, is philosophically distinct from quantity, or quantitas, and so it is unclear how quantification can serve to modulate quality. Is it thus possible for quantification to enhance quality of life? We propose here that an interpretivistic conception of quantification may offer a more valid approach by which to address quality of life in sociological research.
