title: Effect of triphenylphosphate flame retardant on properties of polybenzoxazines

description: To enhance flame retardancy of polybenzoxazines, non-halogenated phosphorus compound has been evaluated for its potential flame retardant. In this research, the resulting flame retardanted polybenzoxazines were prepared by mixing phosphorus flame retardant with three types of arylamine-based benzoxazine resins. Their fire resistance, thermal, and mechanical properties were investigated. The weight ratios of benzoxazine resins/TPP were varied to different phosphorus content. DSC results indicated that, in the presence of TPP, the onse and maximum temperature of the exothermic peak due to the ring opening polymerization of benzoxazine resins shifted to lower temperature. From TGA results, The degradation temperatures at 5% weight loss of polybenzoxazines were reduced. All polybenzoxazines possessed relatively high char yield, which increased as the TPP content increased. This implied that their flame retardancy could be enhanced. The flame-retardancy of these thermosets was evaluated by limiting oxygen index (LOI) and and UL-94 vertical tests. Upon adding 10 wt% of TPP, LOI increased from 23.5, 23, 22 to 26, 25, 24, for BA-a, BA-mt, and BA35x, respectively. Furthermore, the flammability was found to be in an order of BA-a

title: Vaterbilder in Peter Hartlings Nachgetragene liebe, Christoph Meckels Suchbild. Uber meinen vater und Elisabeth Plessens Mitteilung an den Adel

description: Die vorliegende Arbeit beschaftigt sich mit der Darstellung von drei Vaterfiguren in Nachgetragene Liebe (1980) von Peter Hartling, Suchbild. Uber meinen Vater (1980) von Christoph Meckel und Mitteilung an den Adel (1976) Von Elisabeth Plessen. Untersucht wird die Darstellung der Vaterfiguren im Zusammenhang mit anderen Figuren, in erster Linie mit den Kinderprotagonisten. Herangezogen werden sowohl die sozialen und politischen Ereignisse, als auch die Elemente aus dem Lebenslauf der Autoren. Aus der Untersuchung geht hervor, dass die Vaterbilder in den drei Werken negativ prasentiert werden. Diese negativen Bilder, namlich die unerwunschten und nicht nachzuahmenden, hangen mit dem ideologischen Standpunkt der Kinderprotagonisten zusammen: Die Vaterfigur in Nachgetragene Liebe wird als schweigsam, introvertiert, unfahig in Kommunikation und Liebesbezeugungen, und nicht zuletzt als Gegenbild zum, heldenhaften "Adolf Hitler prasentiert. In Suchbild. Uber meinen Vater und Mitteilung an den Adel wird die Darstellung der Vaterbilder von der ideologischen Ambivalenz gepragt. Lebenswerte und Lebensstil der Vaterfiguren sind ebenso wie lyrische Eskapaden bzw. Standesbewusstsein mit der Realitatswahrnehmung und der Verstrickung in den Nationalsozialismus gekoppelt, durch die die Trennung zwischen den Ideologien der Vater-und der Kinderfiguren gekennzeichnet ist. Die Darstellung der negativen Vaterbilder funktionierl jedoch in allen drei Werken auf verschiedene Weise: In Nachgetragene Liebe betont sie die Fehlerhaftigkeit des Sohnes in der Kindheit und ermoglicht eine Versohnung, wahrend sie in Suchbild und Mitteilung an den Adel als eine kritische Reaktion der Kinder auf die Ideologie der Vaterfiguren dient

title: Preparation of rigid polyurethane foam catalyzed by nickel and cobalt complexes

description: Transition metal complexes, namely M(en)₂, M(en)₂(sal)₂, M(trien) and M(trien)(sal)₂ (M = Ni and Co), were synthesized and used as catalysts for the preparation of rigid polyurethane foams (PURFs). The reaction times, physical and mechanical properties of PURFs were investigated and compared to those prepared by commercial catalyst, N,N-dimethylcyclohexylamine (DMCHA). UV-vis spectroscopy, IR spectroscopy, elemental analysis and atomic absorption were used to characterize the transition metal complexes catalysts. ATR-IR technique was used to study isocyanate (NCO) conversion and polyisocyanurate/polyurethane (PIR/PUR) ratio in the PURFs. The polymerization reaction of foaming preparation is exothermic reaction. The maximum reaction temperature is in the range of 114-125 ℃. During the foam preparation, cream time, gel time, tack-free time and rise time were investigated. The results showed that the apparent density of PURFs was in the range 42.3-73.9 kg/m³. Co complexes showed better catalytic activity than Ni complexes. Compressive strength of PURF prepared from Ni(trien)(sal)₂ was better than that prepared from DMCHA. PURFs obtained from Ni(en)₂ and Co(en)₂ showed similar thermal decomposition with that obtained from DMCHA catalyst. Thermal conductivity of PURFs showed that PURFs catalyzed by Co(trien) and Co(en)₂ gave thermal conductivity similar to that catalyzed by DMCHA

title: The determinants of corporate governance oractices: Empirical evidence from Thailand

description: This study investigates the effects of firms’ ownership structure, firm characteristics, and firm performance on corporate governance practices of firms listed in The Stock Exchange of Thailand (SET) during 2007-2008 by using multiple regression analysis. Firm’s ownership structure consists of ownership concentration, institutional ownership, foreign ownership, government ownership, family ownership, and political connection. Firm characteristics are firm size, growth, intangible assets, and leverage. For firm performance, this study considers both accounting performance and market performance based on return on net assets (RONA) and Tobin’s Q as the proxies, respectively. According to agency theory (Jensen and Meckling, 1976), this study hypothesizes that firms’ ownership structure has effects on corporate governance practices of the firm as well as the firm characteristics. In addition, this study also hypothesizes that firms with good performance will have strong corporate governance practices. Consistent with the above hypotheses, this study finds that firms with high institutional ownership, government ownership, or family ownership have strong corporate governance practices, as measured by corporate governance index (CGI). But firms with high concentration ownership have weak corporate governance practices. For firm characteristics, large firms have strong corporate governance practices while high levered firms have weak practices. Firms with high market performance also have strong corporate governance practices. Nevertheless, this study finds that there are five variables that are not significant associated with corporate governance practices, which are foreign ownership, political connection, firm growth, firms intangible assets, and firm accounting performance. Overall, these results imply that ownership structure, firm characteristics, and firm performances are the determinants of corporate governance practices of Thai listed firms even if not all of the variables are significant.

title: Bioactive compounds from Ma-Khan Zanthoxylum limonella Alston

description: The CH₂Cl₂ and MeOH extracts from different parts, and the essential oils of the fruits of Z. limonella were preliminarily screened for antimicrobial and antioxidant activities. The essential oil and the CH₂Cl₂ extract of the stems exhibited the most potent antimicrobial and antioxidant activities. The essential oils contained monoterpene as a major component such as sabinene (42.73%), limonene (39.05%), and terpinen-4-ol (5.40%). The essential oil and terpinen-4-ol exhibited strong activity against tested phytopathogenic fungi. In addition, the crude essential oil and sabinene possessed a broad spectrum antibacterial activity. The rate of time killing of the essential oil and sabinene appeared to be time and concentration dependent against meticillin sensitive S. aureus (MSSA), meticillin resistant S. aureus (MRSA), E. coli, and extend-spectrum β-lactamase producing E. coli (ESBL). The chromatographic separation of the CH₂Cl₂ extract of the stems led to the isolation of a new quinoline alkaloid, 4-methoxy-3-(3-methyl-2-oxobut-3-enyl)quinolin-2(1H)-one (6), along with five known compounds, (-)-asarinin (2), dihydroalatamide (4) and (-)-tembamide (7), a furoquinolone alkaloid, dictamnine (3), and a benzophenanthridine alkaloid, N-nornitidine (5). The IC₅₀, MIC, and MFC values against tested fungi of compound 3 were more potent than the CH₂Cl₂ extract of the stems. On the other hand, the MIC and MBC values of the CH₂Cl₂ extract of the stems and compound 3 were active against tested Gram-positive bacteria and yeast (C. albicans). Compound 3 was determined as a major compound and possessed the antifungal and antibacterial activities. The antioxidant capacity of the CH₂Cl₂ extract of the stems, essential oil and some isolated compounds were determined for primary antioxidative potential in cell-free system (DPPH and TEAC assay) and extended to prostate cancer cell lines, PC-3 and DU-145. The CH₂Cl₂ extract of the stems, compounds 3, 4, and 7 showed higher antioxidant capacity in cell free system than that of the essential oil of fruits and its major components. The CH₂Cl₂ extract of the stems and compounds 3, 4, and 7 seemed to act through GSH level and CAT activity. The essential oil of the fruits has high possibility of regulate CAT capacity than GSH level in both cell lines

title: The impact of spatial scale: exploring urban butterfly abundance and richness patterns using multi-criteria decision analysis and principal component analysis

description: Modelling changes in biodiversity has become a necessary component of smart urban planning practices. However, concepts such as biodiversity are often evaluated using area-based composite indices, the results of which are heavily reliant on specific parameters chosen. This paper explores the design and implementation of a butterfly biodiversity index by comparing two widely accepted modelling techniques: principal component analysis and spatial multi-criteria decision analysis (MCDA). A high degree of scale dependency has been demonstrated in previous studies exploring the use of area-based composite measures. To evaluate the impact of scale, each model was assessed at two different spatial resolutions. The outcomes were analyzed, mapped and compared using ordinary least squares, geographically weighted regression and global Moran’s I to evaluate relative biodiversity patterns across the City of Toronto, Canada. The Urban Butterfly Index - City of Toronto includes a geodatabase that consists of shapefiles of various geographic information used to model urban biodiversity and the butterfly observation points provided by the Ontario Butterfly Atlas. The Ontario Butterfly Atlas (OBA) is a program created and administered by the Toronto Entomologists’ Association (TEA), a non-profit organization that aims to educate and inform the public about local insect populations. Volunteers submit species observations throughout the year including important attribute data such as location (i.e., GPS coordinates or detailed location description to be verified), species name, observation date, adult and immature counts (TEA 2019). The OBA dataset was used as the benchmark variable in each regression analysis performed (i.e., species abundance or richness per area). Each geographic dataset was aggregated and summed by areal unit (i.e., Census Tracts or Dissemination Areas) and combined into a set of composite index scores using either principal component analysis (PCA) or spatial multi-criteria decision analysis (i.e., Weighted Linear Combination). Tabular files used in the Ordinary Least Squares (OLS) and Geographic Weighted Regression (GWR) are also provided and include the benchmark variable of butterfly observations per area (i.e. "SA07_Ha" and "SR07_Ha"), as well as the final PCA (i.e., "PCAF") and WLC scores (i.e., "WLCF"). Findings indicate that the impact of spatial scale was significant, whereby the coarser resolution models (i.e., Census Tracts) were found to be more highly correlated with biodiversity, compared to the finer resolution models (i.e., Dissemination Areas). The results of this study contribute to a growing body of literature that explores key conceptual questions regarding the robustness of GIS-based MCDA, the impact of scale in urban ecology studies, and the use of composite indices to manage spatial ecological data.

title: Bromodomain and HDAC inhibitors equivalently overcome PI3K/AKT inhibition resistance in cancers

description: Blocking BRD4 or HDACs induces paradoxically similar gene expression, comparably attenuates PI3K/AKT inhibitor resistance in multiple cancer cells. PI3K/AKT inhibitors induce global loss of histone acetylation. While in the resistant cells, specific genome loci gain H3K27 acetylation and BRD4 binding coupled with up-regulation of selective genes. These loci and genes are vulnerable to BRD4 or CBP/p300 bromodomain inhibitors, as well as HDAC inhibitors. Inadequate occupancy of HDACs on these loci permits gain of H3K27 acetylation and BRD4 recruitment after AKT inhibition. Bromodomain inhibitors directly suppress these loci; HDAC inhibitors induce histone hyper-acetylation outside these loci, offering competitive BRD4 binding sites, re-localizing BRD4. To suppress these loci, genes, and relative resistance, multi-bromodomain inhibitor NEO2734 and HDAC inhibitors are equivalent in effects.
