The Symmetry of Aurivillius Ceramics
Fuentes, Luis,Fuentes, Maria E.,Camacho, Hector Korea Crystallographic Association 2001 韓國結晶學會誌 Vol.12 No.4
Structure-physical properties relationships for Aurivillius ceramics are discussed, with empha-sis in symmetry considerations. Single-crystal materials and polycrystal ceramics are analysed. Electric and magnetic coupling properties are considered. Colour Symmetry Groups and Texture Analysis tool are emploed. Symmetry conditions for polarisation vectors and inverse pole figures related to Aurivillius phases are given. The influence of crystallographic texture of the physical properties of polycrystalline Aurivillius ceramics is evaluated.

<P><B>Abstract</B></P> <P>Non-solvent precipitated starch (non-SPS) is a novel component for starch-based emulsions. Herein, three non-SPS materials were prepared using ethanol as a precipitant of waxy maize starch granules (WMs). The WMs were either untreated (SP) or pre-treated via acid-hydrolysis (AHSP). In addition, SP was modified using n-octenyl succinic anhydride (OSA), yielding OSASP. This study aimed to investigate the influence of the non-SPS preparation method on the size, molar mass (M), and apparent density (ρ<SUB>app</SUB>) of the materials when subjected to different dissolution/dispersion procedures using asymmetrical flow field-flow fractionation (AF4). The results showed that the molar mass, size, and apparent density depended on the type of non-SPS with a decrease in M<SUB>w</SUB> (1.8–9.4 g/mol) and r<SUB>rms</SUB> (60–148 nm) upon re-dispersion in different media in the order: SP > OSASP > AHSP. Moreover, different types of non-SPS materials displayed different conformational properties and were stable in aqueous solution at room temperature in the investigated time (24 h).</P> <P><B>Highlights</B></P> <P> <UL> <LI> Non-solvent precipitated starch (non-SPS) is obtained from waxy maize starch. </LI> <LI> Precipitated starch properties after re-dispersion depend on the preparation method. </LI> <LI> Precipitated starch has an amorphous structure. </LI> <LI> Re-dispersion at room temperature can lead to dissolution of starch precipitates. </LI> <LI> Size, molar mass, apparent density, and conformational properties are determined. </LI> </UL> </P>

Purpose: The aim of this study was to analyze the anatomical dimensions of the buccal bone walls of the aesthetic maxillary region for immediate implant placement, based upon cone-beam computed tomography (CBCT) scans in a sample of adult patients. Methods: Two calibrated examiners analyzed a sample of 50 CBCT scans, performing morphometric analyses of both incisors and canines on the left and right sides. Subsequently, in the sagittal view, a line was traced through the major axis of the selected tooth. Then, a second line (E) was traced from the buccal to the palatal wall at the level of the observed bone ridges. The heights of the buccal and palatal bone ridges were determined at the major axis of the tooth. The buccal bone thickness was measured across five lines. The first was at the level of line E. The second was at the most apical point of the tooth, and the other three lines were equidistant between the apical and the cervical lines, and parallel to them. Statistical analysis was performed with a significance level of $P{\leq}0.05$ for the bone thickness means and standard deviations per tooth and patient for the five lines at varying depths. Results: The means of the buccal wall thicknesses in the central incisors, lateral incisors and canines were $1.14{\pm}0.65mm$, $0.95{\pm}0.67mm$ and $1.15{\pm}0.68mm$, respectively. Additionally, only on the left side were significant differences in some measurements of buccal bone thickness observed according to age and gender. However, age and gender did not show significant differences in heights between the palatal and buccal plates. In a few cases, the buccal wall had a greater height than the palatal wall. Conclusions: Less than 10% of sites showed more than a 2-mm thickness of the buccal bone wall, with the exception of the central incisor region, wherein 14.4% of cases were ${\geq}2mm$.

Background The survival rate of newborns with severe congenital abdominal wall defects has increased. After successfully addressing life-threatening complications, it is necessary to focus on the cosmetic and functional outcomes of the abdominal wall. Methods We performed a chart review of five cases treated in our institution. Results Five patients, ranging from seven to 18 years of age, underwent the following surgical approaches: simple approximation of the rectus abdominis fascia, the rectus abdominis sheath turnover flap, the placement of submuscular tissue expanders, mesh repair, or a combination of these techniques depending on the characteristics of each individual case. Conclusions Patients with severe congenital abdominal wall defects require individualized surgical treatment to address both the aesthetic and functional issues related to the sequelae of their defects.

Bacopa monnieri (L.) Wettst. could be of interest in the control of symptoms of Parkinson's disease, but clinical evidence of its efficacy is lacking. This clinical trial assessed the effects of an extract of B. monnieri on parameters that are related to Parkinson's diseases. Twenty volunteers with Parkinson's disease were recruited for a primary, interventional, controlled, parallel, double-blind clinical study. The volunteers were assigned to treatment with either a commercial B. monnieri extract (225 or 450 mg/day) or placebo. The Parkinson's Disease Quality-of-Life (PDQL) questionnaire was applied, and motor activity was assessed before treatment and 30, 60, and 90 days after treatment with the B. monnieri extract or placebo. Characteristics such as age, body weight, and height were also collected. No differences in parkinsonian and systemic symptoms, emotional function, or social function were observed between. The delta percent (Δ%) showed time-dependent improvements in emotional function with B. monnieri treatment at the daily dose of 450 mg. A strong correlation was found between quality of life and motor outcomes at baseline and 30 days of treatment with B. monnieri, and a moderate correlation for 60 and 90 days of treatment with B. monnieri when compared with baseline time. A moderate correlation was found between motor outcomes and Hoehn and Yahr stages at baseline. Our results suggest that B. monnieri extract can improve emotional function in Parkinson's disease patients, but further clinical trials are needed to confirm this possibility.

This paper explores the vulnerability of women to trafficking as an avenue to prostitution entry. It attempts to provide better understanding of why Filipino women and girls in particular are vulnerable to trafficking. This includes victim narrative to attest the method of recruitment, transportation and debt bondage as part of trafficking activity chains. It also describes the degrading and inhumane realities in the red lights districts as trafficked women reached the place of destination within the country. While it is understood that there are many factors increasing the vulnerability of women, reports showed that poverty in the Philippines and family dysfunctionality significantly contribute to the trafficking and sexual exploitation of women. Given the immensity of the problem and its complex nature, trafficked women who end up into prostitution are maltreated and have experienced various forms of abuse, torture and slavery. In response to the violence and degradation of women’s rights, this article further offers insights about the practices and approaches in the prevention, advocacy and support to the women towards exit path, healing, empowerment and integral transformation.
