Control gráfico de formas y superficies de transición
Authors:   , Crespo Cabillo Isabel
Published: September 2023

El treball parteix de la idea que l'arquitectura és essencialment geomètrica i vol demostrar que el coneixement de la geometria és imprescindible per a arribar a fer una obra d'arquitectura.
S'estudien uns 30 exemples que tenen algun cas de forma de transició. És a dir elements la forma dels quals és la conseqüència de construir una figura que es transforma des d'un extrem a l'altre canviant el seu perfil de manera continua. Com per exemple pilars que tenen una base diferent del seu capitell, o voladius que varien la seva secció. Com a conseqüència d'això apareixen superfícies amb unes característiques geomètriques peculiars, que poden ajudar a l'objectiu de l'obra o poden entorpir la seva construcció. El coneixement en profunditat d'aquestes superfícies és imprescindible per que l'obra es pugui construir de manera raonable.
Els exemples han estat estudiats des de tots els punts de vista que s'ha cregut interessant per a comprendre el perquè de la seva forma. Després s'ha estudiat en detall, fins a l'últim aspecte geomètric i constructiu, com es volia la seva forma, com s'ha comprès i com s'ha acabat construint.
El focus d'atenció ha estat deliberadament centrat en l'arquitectura de les formes corbes i on més exemples de transició he trobat ha estat en l'arquitectura de formigó dels anys 1950', una arquitectura de formes toves amb una estreta i poc evident relació amb la construcció de vaixells.
La connexió entre la forma pensada i la forma construïda es dona en el dibuix per que es regeix per les mateixes lleis que la construcció.
Les formes corbes obliguen a un coneixement elevat de geometria que posa en condicions de treballar còmodament amb elements tridimensionals i per això cal no apartar aquesta docència dels plans d'estudis de les escoles d'arquitectura (sempre que es pretengui que sigui l'arquitecte qui controli la construcció d'edificis que confien en la forma la seva capacitat expressiva).
Traçat de perspectiva curvilinea de pantalla cilíndrica mitjançant sistemas informàtics
Authors:   , Font Comas Joan
Published: September 2023

L'objectiu bàsic del present treball és, el de, partint de l'estudi de Martínez-Quintanilla, plantejar un sistema informatitzat per al traçat de la perspectiva curvilínia de pantalla cilíndrica, capaç de poder representar, amb una qualitat gràfica raonablement alta, conjunts arquitectònics o urbanístics d'una certa complexitat, és a dir, de bon principi quedà clar que, perquè el treball reixís en els seus objectius, calia que el sistema permetés la consecució de dibuixos en perspectiva de pantalla cilíndrica, representats sobre paper amb eliminació de línies ocultes i amb el grau de complexitat normalment exigible per a un tipus de perspectiva panoràmica com aquesta.

El treball s'estructura en cinc capítols:

En el Primer Capítol s'exposen els conceptes generals de la perspectiva curvilínia de pantalla cilíndrica i, seguint l'estudi de Martínez-Quintanilla, es fa una breu repassada als seus antecedents històrics, acabant per una exposició dels trets bàsics del sistema manual proposat per Martínez-Quintanilla.

El Capítol 2 analitza els grans temes que cal afrontar per tal de plantejar el tractament informàtic de la perspectiva de pantalla cilíndrica. Un repàs a les alternatives possibles permet prendre un seguit d'opcions que configuren ja l'esquelet de l'aproximació que farem al tema. El Capítol acaba amb una descripció detallada de l'estructura d'informació que s'adopta per al plantejament informàtic del problema, punt -no cal dir-ho- d'importància cabdal per al seguiment de la resta del treball.

El Capítol 3 s'ocupa de la descripció del sistema desenvolupat per a la creació dels models a representar, i hi són estudiades un gran nombre de situacions compromeses, exposant-se algorismes apropiats per a la seva resolució.

El Capítol 4 estudia la visualització dels models mitjançant perspectiva curvilínia de pantalla cilíndrica. En concret s'hi estudia l'obtenció i representació interna de la projecció, i l'eliminació de línies ocultes per a traçat vectorial, considerant les característiques específiques d'una perspectiva en què la major part de les rectes apareixen com a corbes i en la qual desapareix el concepte de pla d'esvaïment.

Per últim, en el Capítol 5 s'exposen un seguit de consideracions i optimitzacions deduïdes de les primeres experiències d'utilització dels Sistemes, experiències encara un tant restringides, ateses les limitacions de l'equip utilitzat, però que permeten extreure conclusions certament importants, de cara a la programació d'una segona versió dels Sistemes, ja sobre els nous equips de l'E.T.S.A.Vallès.
Dibujar después de 1910

Wilhelm worringer anticipa solo una actitud frente a la abstraccion: la de mondrian. El transito hacia la abstraccion fue vivido desde dos actitudes distintas: la primera compulsiva y catarquica: se abre una fisura entre el sujeto y el mundo, y los nuevos vinculos surgiran de una autentica transformacion. La segunda necesita nexos. Se trata de un proceso que conduce a la abstraccion desde inevitables dependencias con lo natural. El origen de las transformaciones de la imagineria pictorica en este siglo deriva, determinantemente, de las restricciones que se imponen al gesto y de las consecuencias del empleo de tecnicas de grabado. La escultura moderna no rodiniana (picasso) proviene de la mutacion escultorica de la pintura. La diagonal es una linea que implica una relacion particular en pintura, porque realmente manifiesta inestabilidad respecto a ella. En rodchenco no hay secuencias desde la pintura: el ataque contra ella es frontal. El analisis de la forma de proceder sistematica en la pintura de seurat obliga a deshacerse de la idea de una correlacion consecuente entre ciencias y pintura. Entre ambas experiencias no existe el vacio, sino una forma de relacion que tiene que ver con el fluir de las ideas de un tiempo, pero ese tipo de transferencias no resisten las exigencias del procedimiento cientifico. Los limites del cubismo los establece, entre otros, juan gris. El nucleo central de esa experiencia (picasso-brake) como constatamos en el analisis del cuaderno 026 de picasso rechaza las estratagemas compositivas. Los hallazgos procesuales implicitos en la experiencia cubista de los años doce-trece (picasso) son transferidos a la arquitectura y lo que sucede en el seno de la vanguardia sovietica es explicable, fundamentalmente, desde ese punto de vista.

The Impact Of Edc's Marketing, Service, And Infrastructure Strategies On The Growth Of Savings Deposits At Bank Rakyat Indonesia Surabaya Pahlawan Branch
Authors: Septianingrum Wike Dwi
Published: September 2023

Banking strategy requires fast and instant service to provide "excellent service" to customers. One of the marketing methods used as technology development in the banking industry, for example at PT Bank Rakyat Indonesia Surabaya Pahlawan Branch, is a marketing approach using Electronic Data Capture (EDC). This tool has the benefit of growing third-party funds, especially savings funds and fee-based income obtained from every transaction carried out on the EDC machine. In addition, there are efforts to increase the amount of savings, especially low-cost funds (savings) in a way that is more dominant to the number of third-party funds, to reduce the cost of funds and is expected to generate an increase in the value of net interest margin (NIM) despite the current tight bank liquidity. The purpose of this study is to see the influence of Marketing Strategy, Service Strategy, and Electronic Data Capture (EDC) Infrastructure on the Growth of Savings Deposits at PT Bank Rakyat Indonesia Surabaya Pahlawan Branch. This study used multiple linear regression with the help of the SPSS version 23 application to help with data processing. The results showed that the variables Marketing Strategy (X1), Service Strategy (X2), and Electronic Data Capture Infrastructure (X3) had a positive and significant influence on the increase in Savings Deposit Growth (Y) by the regression coefficient.

We have been tweeting about what APIs that are down related to R pacakges we make, but we thought we would write up a proper blog post on the issue. NCBI services are still up! NCBI is within NIH, which is within the Department of Health and Human Services.

Background: Several studies suggest a protective role of bilirubin against oxidative damage during the neonatal period. ADA1*2 allele has been found associated with higher bilirubin levels in newborns and with a protective action against bronchial asthma. Thus the relation between ADA1 and asthma could be mediated by events occurring during the early extrauterine life. Moreover the increased prevalence of allergic diseases in western populations parallels the widespread practice of phototherapy during the neonatal period. These observations prompted us to reevaluate our previous data and show new observations. Methods: Data from 2729 previously studied subjects, from 53 subjects studied at birth and after 30 years and from a survey of phototherapy frequency in four Italian Hospital including 7392 newborns are reported. Results: ADA1*2 allele carriers are less represented among asthmatic subjects than in controls (p=0.0004). ADA1*2 allele carriers among newborns undergoing phototherapy for hyperbilirubinemia is higher when compared to newborns not undergoing this treatment (p=0.006). In infants treated by phototherapy, the maximum bilirubin level attained during the first few days of life positively correlated with the ADA1*2 allele dose (p=0.001). Among subjects studied at birth, allergic rhinitis and/or conjunctivitis are more frequent among those treated with phototherapy than among those not treated (p=0.046). Conclusions: These observations support our hypothesis that ADA1*2 allele through an increase of bilirubin level in the neonatal period protects infants from oxidative stress and favours Th2-Th1 switching thus preventing allergic manifestations in later periods of life.

Simple, accurate and reliable kinetic spectrophotometric method for the determination of fluvastatin sodium (FVS) in pure form and pharmaceutical formulations has been described. The method is based on the formation of colored product between FVS and 4-chloro-7-nitrobenzofurazan (NBD-Cl) in acetone medium at 55 ± 2ºC. The reaction is followed spectrophotometrically by measuring the increase in absorbance at 462 nm as a function of time. The rate data and fixed time methods were adopted for constructing the calibration curves. The linearity ranges were found to be 15.0-50.0 and 10.0-90.0 μg mL-1 for rate data and fixed time methods, respectively. The limit of detection for rate data and fixed time methods is 0.017 and 0.134 μg mL-1, respectively. The proposed methods have been successfully applied to the determination of fluvastatin sodium in pharmaceutical dosage forms with no interference from the excipients. Statistical comparison of the results shows that there is no significant difference between the proposed and official methods.

Objective: A 3-dimensional alginate bead culturing method using rabbit articular chondrocytes was studied for the screening of the effectiveness of drugs for articular diseases. Design: The beads cultured with IL-1β, TGF-β, and Hyaluronan (HA) were evaluated histochemically with Alecian blue and immunohistochemically with CS-56 antibody. Chondrocytes in alginate beads were arbitrarily classified into four groups: 1) chodrocyte surrounded with cell-associated matrix (CAM) in which proteoglycan (PG) was positively stained (PG-possitive chondrocyte); 2) chondrocyte with PG-negative CAM; 3) PG-positive CAM alone, and 4) PG-negative CAM alone. Total sulfated GAG concentrations in the culture media were quantitated by dimethylmethylene blue (DMMB) assay. ProMMP-3, TIMP-1 and -2 concentrations in the culture media were determined by sandwich enzyme immunoassays. Results: Significant increase of PG-nagative cells were immunohistochemically found by IL-1β stimulation. The pretreatment with TGF-β almost fully suppressed those increase of PG-negative cells by IL-1β. Both GAG and proMMP-3 concentrations in the culture media were significantly increased after IL-1β stimulation. There were no significant differences in both TIMP-1 and TIMP-2 concentrations in the culture media with or without IL-1β stimulation. 800-kDa HA reduced significantly the number of PG-negative cells and proMMP-3 concentration in the culture media, but showed no effects on the concentrations of both TIMPs. Conclusions: Because this 3-dimensional chondrocyte culture in alginate beads is close to in vivo conditions, this method can be used for evaluation of the effectiveness of novel drugs for articular diseases.

Published: September 2023

A selective and simple spectrophotometric method has been developed for the determination of phenylpropanolamine HCl (PPA) in its dosage forms. The method was based on the formation of a colored N-vinyl chlorobenzoquinone derivative of PPA through its reaction with 2,3,5,6-tetrachloro-1,4-benzoquinone in presence of acetaldehyde. The colored product exhibits maximum absorbance at 650 nm. Different experimental parameters affecting formation and stability of the product were carefully studied and optimized. The factors affecting the reaction were studied and optimized. The stoichiometry of the reaction was determined, and the reaction pathway was postulated. The absorbance concentration plot was rectilinear over the range of 5-100 µg/mL with Limit of Detection (LOD) and Limit of Quantitation (LOQ) of 0.244 µg/mL and 0.74 µg/mL respectively. The analytical performance of the method was fully validated, and the results were satisfactory. The proposed method was successfully applied to the determination of PPA in its commercial dosage forms including tablets, capsules and syrups with good recoveries. Statistical comparison of the results with those of the comparison method showed good agreement and proved that there was no significant difference in the accuracy and precision between the reference and the proposed methods. The mechanism of the reaction pathway was postulated.

Anxiety is a source of concern to the clinicians as it is co morbid with other mental disorders, particularly depression and learning disabilities, and it causes low self-esteem. The aim of this research was to evaluate the prevalence of anxiety disorder amongst secondary school children in Port Harcourt. A two-staged stratified sampling method was used to select the schools. Structured questionnaire based on Vanderbilt ADHD Diagnostic Teacher Rating Scale for anxiety and depression symptoms was use in evaluating the students. The questionnaires administered to the students were filled with the assistance of the researchers and the classroom teachers. Direct verbal interview was conducted for those noted to have symptoms of any of the various types of anxiety disorders and fears. Out of 885 students, 91 met the criteria for the diagnosis of anxiety/ depression disorder; prevalence was 10.28%, age range was 9-18 years. There were 37 males and 54 females giving a male: female ratio of 0.69:1. Majority 52 (57.14%) of the children lived with their parents, 28 (30.77%) of them lived with family relations and 11 (12.09%) of them were working as house helps to other families. The reasons given for being anxious were poor self image, fear of death, repeated physical and sexual abuses by their care givers and other adults. Learning disability was the major associated co morbid disorder (18.68%). Generalized anxiety was the most common type of anxiety disorder identified (32.97%). Anxiety disorders are debilitating chronic conditions. When it affects school aged children it contributes significantly to poor academic performance.
