Sustainability Assurance Factors and Determinants in ASIA

This paper examines the factors and determinants of sustainability assurance (SA) for a sample of firms in Asia in the period of 2012-2016. We find that the quality and quantity of SA reports have made a steady improvement in recent years in Asia with a total of 2,196 assurance reports. We also find that SA factors are associated with both quality and quantity of sustainability reporting (SR) and assurance obtained from Big 4 and some of the United Nations Sustainable Development Goals (SDGs) relevant to environmental, social, and governance (ESG) dimension of sustainability performance. Among Asian countries, five that are significantly associated with the quantity and quality of SA are Japan, Singapore, Philippine, South Korea, and Thailand. In addition, five industries that are significantly associated with the quantity and quality of SA are energy, financial, material, healthcare, and telecommunication services.
Radiation effects in MOS devices caused by x‐ray and e‐beam lithography

In this study we have found that electron–beam and x‐ray irradiations of metal (or polysilicon) ‐oxide‐semiconductor devices performed at typical PBS or PMMA exposure levels create temperature‐bias‐stress (TBS) instability. Experimental results can be most reasonably explained by assuming that exposure to both of these types of ionizing radiation causes mobilization of positive charge in the insulator. The positive charge is forced closer to the semiconductor–gate‐oxide interface during the positive bias phase of the TBS test. This damage mechanism was found in HCl, H2/O2, and dry grown oxides. HCl oxides exhibited the effect the least of the three oxide types studied. N2 anneals performed at 500° and 900°C, and H2 anneals performed at 500°C (all for 30 min) did not substantially reduce TBS instability. A 900°C anneal in H2 for 30 min did create a marked reduction in the TBS‐induced instability.

The cathode spot plasma in low-current air and vacuum break arcs

The radiation from active cathode spots in air and vacuum break arcs was investigated by different experimental techniques: streak camera recording, time-resolved and time-integrated spectroscopy. Spot rotation has been found with two frequencies omega 1=2*105 Hz and omega 2=4-6*107 Hz, and two characteristic radial velocities V1=21 m s-1 and V2=130 m s-1. From spectroscopic measurements, degeneration of the upper excited atom states is deduced, corresponding to a strong non-ideality of the cathode spot plasma with consequences for the particle density (N>1028 m-3).
Discharge mechanisms in liquid nitrogen with thermally induced gas bubbles

Discharge voltages of a sphere-plane electrode arrangement in subcooled liquid nitrogen stressed with impulse voltages were investigated. Tests were performed with and without thermally generated bubbles between the electrodes. Polarity effects could be observed at higher gaps and lower utilization factors. These effects are explained by the occurrence of positive and negative streamers, which have different propagation mechanisms. The measured discharge voltage with thermally generated bubbles is compared to calculated values using Paschen's law.
Effect of poly(propylene carbonate) on the crystallization and melting behavior of poly(β‐hydroxybutyrate‐co‐β‐hydroxyvalerate)

The crystallization and melting behavior of poly(beta-hydroxybutyrate-co-beta-hydroxyvalerate) (PHBV) and a 30/70 (w/w) PHBV/poly(propylene carbonate) (PPC) blend was investigated with differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR). The transesterification reaction between PHBV and PPC was detected in the melt-blending process. The interaction between the two macromolecules was confirmed by means of FTIR analysis. During the crystallization process from the melt, the crystallization temperature of the PHBV/PPC blend decreased about 8 degreesC, the melting temperature was depressed by 4 degreesC, and the degree of crystallinity of PHBV in the blend decreased about 9.4%; this was calculated through a comparison of the DSC heating traces for the blend and pure PHBV. These results indicated that imperfect crystals of formed, crystallization was inhibited, and the crystallization ability of PHBV was weakened in the blend. The equilibrium melting temperatures of PHBV and the 30/70 PHBV/PPC blend isothermally crystallized were 187.1 and 179 degreesC, respectively.

Mimicking P450 processes and the use of metalloporphyrins

Metalloporphyrins (MPs) are known to catalyze in vitro a broad range of cytochrome P450-mediated reactions occurring in vivo. Most of the biomimetic research using MPs in oxidative catalysis has been directed towards the oxidation of organic compounds presenting significant reactivity features in one functional group. Much less effort has been made to imitate the oxidation of more complex molecules, with a range of functionalities, such as drugs or other xenobiotics. By varying the structure of the porphyrin, the metal ion, the oxidant, and the reaction conditions, it is possible to modulate the regioselectivity of the oxidation reactions. Recently, and along with studies on the synthesis and reactivity of porphyrins, chlorins, and phthalocyanines, our group was able to develop an interesting line of research in the field of biomimetic oxidation of organic compounds using environmentally benign hydrogen peroxide as oxidant and Mn(III) or Fe(III) porphyrin complexes as catalysts. The more up to date results obtained in such work are reviewed here.
Canonical two‐range addition theorem for slater‐type orbitals

The radial Slater-type orbitals (STO) can be simply obtained by repeated parametric differentiation of the Yukawa Potential with respect to α. A new compact two-range addition theorem (AdT) for the STO is herein derived by explicit parametric differentiation of the well-known Yukawa AdT. The resulting addition formula is combined with the single-range AdT for solid spherical harmonics to present a new AdT for three-dimensional spherical coordinate STOs. We advance the proposition that this formula is “canonical” in the same sense that the Laplace expansion of the Coulomb potential is considered canonical. We demonstrate how this procedure can be employed for all exponential-type orbitals. © 2012 Wiley Periodicals, Inc.
Analysis of texture effects on fatigue behaviour of 316L stainless steel

The influence of crystallographic texture on cyclic behaviour, fatigue crack initiation and fatigue life of a 316L austenitic stainless steel was investigated in the low cycle fatigue range at room temperature. Specimens of five different orientations of the rolled sheet were compared to study different textures. It is shown that texture influences the stress-strain response of the material and the fatigue damage (crack density). Moreover, to study the influence of the environment on the fatigue behaviour and the coupling effects with crystallographic aspects, fatigue tests were performed in air and in vacuum. It is shown that the environment modifies both the total crack density and the ratio of transgranular to intergranular cracks. All results are discussed with regard to the relative fraction of and grains oriented for multiple slip or to the fraction of grains favouring single slip behaviour.
Myoinositol to total choline ratio in IDH wild-type gliomas as a prognostic factor on preoperative magnetic resonance spectroscopy

Background: Isocitrate dehydrogenase (IDH) wild-type gliomas tend to be pathologically defined as glioblastomas. We previously reported that, unlike IDH-mutant gliomas, IDH wild-type gliomas showed significantly lower ratios of myoinositol to total choline (i.e., the Ins/Cho ratio) on magnetic resonance (MR) spectroscopy. Given that IDH-mutant gliomas also have much better prognoses than IDH wild-type gliomas, we hypothesized that this lower Ins/Cho ratio is associated with malignancy in adults with supratentorial gliomas. Therefore, we calculated the Ins/Cho ratios of patients with supratentorial IDH wild-type gliomas and investigated their progression free survival (PFS) and overall survival (OS) to determine its utility as a prognostic marker.Methods: We classified IDH wild-type gliomas (n = 30) into two groups based on the Ins/Cho ratios, and compared patient backgrounds, pathological findings, PFS, OS, and copy number aberrations.Results: Compared with the group with high Ins/Cho ratios, the group with low Ins/Cho ratios had shorter PFS (P = 0.020) and OS (P = 0.037) durations. Multivariate analysis demonstrated that the Ins/Cho ratio correlated significantly with PFS (hazard ratio 0.34, P = 0.027). Conclusion: We conclude that the preoperative Ins/Cho ratio can be used as a novel prognostic factor for IDH wild-type gliomas.

Indirect 17O‐magnetic resonance imaging of cerebral blood flow in the rat

Proton T1ρ‐dispersion MRI is demonstrated for indirect, in vivo detection of 17O in the brain. This technique, which may be readily implemented on any clinical MRI scanner, is applied towards high‐resolution, quantitative mapping of cerebral blood flow (CBF) in the rat by monitoring the clearance of 17O‐enriched water. Strategies are derived and employed for 1) quantitation of absolute H217O tracer concentration from a ratio of high‐ and low‐frequency spin‐locked T1ρ images, and 2) mapping CBF without having to transform the T1ρ signal to H217O tracer concentration. Absolute regional blood flow was mapped in a single 3‐mm brain slice at an in‐plane resolution of 0.4 × 0.8 mm within a 5‐min tracer washout time; these data are consistent with the less localized CBF measurements reported in the literature. T1ρ‐weighted imaging yields excellent signal‐to‐noise ratios, spatiotemporal resolution, and anatomical contrast for mapping CBF. Magn Reson Med 49:479–487, 2003. © 2003 Wiley‐Liss, Inc.
Performance of Dye-Sensitized Solar Cells with Natural Dye from Local Tropical Plants

Dye-sensitized solar cell (DSSC) is a class of third generation solar cells that are formed by placing a semiconductor between a photosensitized anode and an electrolyte, which allows the light to pass through the cell. Synthetic dyes, usually ruthenium-based and commonly used in DSSCs, are environmentally toxic and expensive than natural dyes. The aim of the study was to investigate native and cheap sources of natural dyes as photosensitizers for DSSCs using tropical plants. Dyes from four different local plant sources were successfully extracted, prepared, and characterized and were used as alternative, non-toxic, natural photosensitizers. The visible spectra of the extracts with peaks between 430-440 nm suggest that they are dominated by chlorophyll a (430-662 nm) and chlorophyll b (453-642 nm). When observed under ambient conditions, the fabricated DSSCs demonstrated high outputs for OCVmax wherein 433, 397, 311, and 203 mV were obtained using dye-sensitizers from dried talisay leaves (Terminalla catappa), spent coffee grounds (Coffea spp.), fresh talisay leaves, and alugbati fruit (Basella alba), respectively. The observed open circuit potentials were comparable with other reported DSSCs. The output current, fill factor, and cell efficiency can be improved by co-sensitization and increasing the lightscattering capability, among other methods of constructing the DSSCs. Generally, with the limited impacts to the environment and cheap production cost, this research has opened opportunities for application of natural dye from local sources for renewable energy technologies.
Protein Content of Shiitake Mushroom Grown on Nitrogen Soaked Sweetgum Logs

ABSTRACT Shiitake mushrooms are used as a source of protein and meaty flavor in many vegetarian diets. While substrate and geographical location are two factors affecting nutrient content, little research has been done on the nutrient content of shiitake grown in north Alabama. The purpose of this study was to compare the protein and amino acid contents of the ‘West Wind’ strain of shiitake mushrooms grown on sweetgum logs soaked in tap water, versus the protein and amino acid content of the same strain grown on logs soaked in tap water amended with different nitrogen (N) solutions (urea, sulfur-coated urea, and ammonium sulfate), at different rates (0, 3, and 6 g N/L water), and harvested from three successive soakings. Chemical analysis was conducted on samples for protein and amino acids. Analysis of variance showed there was no significant difference in the protein content of shiitake grown on sweetgum logs based on type of nitrogen treatment, rate, or soak period. However, urea showed indications that it may increase protein levels. There was no significant difference in amino acid content based on treatment or rate. Although not statistically significant, there was a trend showing mushrooms from logs soaked at a rate of 3 g N/L water had the highest levels of each amino acid. There were significantly lower levels of amino acids in mushrooms harvested during the summer months. Nitrogen soak solutions did not increase protein or amino acid content, but protein and amino acid contents of shiitake in north Alabama are better understood.
Photophysical and photocatalytic properties of AgInW2O8

A photocatalyst, AgInW2O8, with a layered structure was synthesized. The physical and photophysical properties of the photocatalyst were characterized by XRD, BET measurement, UV−visible diffuse reflectance, and photoluminescence, respectively. The photocatalytic properties of the photocatalyst for H2 evolution with Pt cocatalyst from CH3OH/H2O solution and O2 evolution from AgNO3 solution were observed under UV and visible light irradiation. The AgInW2O8 photocatalyst presented not only the activity of O2 evolution but also the activity of H2 evolution. Also the photocatalyst showed the ability to evolve H2 from pure water under full arc irradiation. On the basis of all the results, the band structure of the photocatalyst was discussed.
Entre chantier et communauté : l’impact du fly-in fly-out sur la communauté de Fermont

Ce memoire s’interroge sur la capacite de developpement des communautes minieres au Canada. Par une etude de cas, la recherche se penche sur l’impact social de l’introduction du fly-in fly-out sur la communaute de Fermont. Construite sur un modele de ville de compagnie, la communaute de Fermont est intimement liee au developpement minier. L’embauche de travailleurs migrants remet en question la raison d’etre ces villes minieres isolees. L’evaluation d’impact social est un outil largement utilise dans le domaine minier et inspire de nombreux travaux en sciences sociales. Le projet s’appuie notamment sur une recherche d’evaluation d’impact social australienne pour etablir les impacts potentiellement percus et vecus a Fermont. La chercheure emploie une methodologie mixte integrant les entrevues semi-dirigees et l’enquete par questionnaire afin de mieux comprendre le contexte particulier de cette communaute nordique. La recherche a permis d’etablir que les impacts directs de la presence des travailleurs se sont amoindris a la fin des travaux d’agrandissement et de demarrage du nouveau chantier minier. Cependant, l’institutionnalisation du fly-in fly-out au sein d’ArcelorMittal entraine des impacts de deuxieme ordre beaucoup plus importants. D’abord, le fly-in fly-out permet aux nouveaux travailleurs d’obtenir un emploi a Fermont sans s’installer de facon permanente avec leur famille, accentuant la structure atypique de la communaute propre aux villes de compagnie. Dans un deuxieme temps, la possibilite d’obtenir un poste fly-in fly-out entraine de plus en plus de departs de travailleurs residents et de leur famille, amplifiant par le fait meme, les impacts sur la communaute.
Hydrolysis of N2O5 on submicron sulfuric acid aerosols

The kinetics of reactive uptake of gaseous N{sub 2}O{sub 5} on submicron sulfuric acid aerosol particles has been investigated using a laminar flow reactor coupled with a differential mobility analyzer (DMA) to characterize the aerosol. The particles were generated by homogeneous nucleation of SO{sub 3}/H{sub 2}O mixtures. In the H{sub 2}SO{sub 4} concentration range 26.3--64.5 wt {degree} the uptake coefficient was {gamma} = 0.033 {+-} 0.004, independent of acid strength. For an acid strength of 45 wt % {gamma} was found to decrease with increasing temperature over the range 263--298 K. From this, temperature dependence values of {minus}115 {+-} 30 kJ/mol and {minus}25.5 {+-} 8.4 J/K mol were determined for the changes in enthalpy and entropy of the uptake process, respectively. The results are consistent with a previous model of N{sub 2}O{sub 5} hydrolysis involving both a direct and an acid catalyzed mechanism, with uptake under the experimental conditions limited by mass accommodation.
Fusarium Head Blight in Canadian Winter Wheat: Utilizing Association Mapping and Genomic Selection for Resistance Breeding

FUSARIUM HEAD BLIGHT IN CANADIAN WINTER WHEAT: UTILIZING ASSOCIATION MAPPING AND GENOMIC SELECTION FOR RESISTANCE BREEDING Harwinder Singh Sidhu University of Guelph, 2020 Advisor(s): Istvan Rajcan Alireza Navabi Fusarium Head Blight (FHB) is a devastating disease of Wheat (Triticum aestivum L.) caused primarily by Fusarium graminearum Schwabe in Canada. Wheat FHB results in yield and produce quality losses. The clearest symptoms of FHB are premature bleaching of spikelets in the field, and fusarium damaged kernels in the harvested seed. Insufficient and costly disease control strategies make breeding for FHB resistance in wheat an ideal choice. There is a lack of FHB resistance sources in the Canadian wheat germplasm and Genome Wide Association Studies (GWAS) can be utilized to identify such sources. Furthermore, as no Quantitative Trait Loci (QTL) provides absolute resistance to FHB, identification of novel sources of resistance is desired. Genomic Selection (GS) has great potential in crop improvement, specifically for quantitative traits. A diversity panel that represents the genetic diversity of the Canadian, i.e., high latitude North American winter wheat was assembled for this thesis and the genetic diversity, population structure, and linkage disequilibrium of the germplasm was studied. To identify QTL associated with FHB, a GWAS study was conducted using the phenotypic data collected at three locations over two years. For understanding the role of number of genotypic markers, population structure, and choice of model in trait prediction modelling, a GS study was conducted. The Canadian Winter Wheat Diversity Panel is a diverse collection of winter wheat capturing diversity both in time and geography from Canada. The panel comprises of seven subpopulations with different LD, allele frequencies, and genetic diversity parameters. Multiple QTL associated with FHB related traits were identified on 13 chromosomes which may harbor genes involved in plant defense and stress response mechanisms. For FHB resistance improvement, the GS study demonstrated that the modelling parameters can be determined based upon the genotypic information available. Deoxynivalenol contamination was one of the traits with the highest prediction accuracy. GS can account for minor effect QTL, which is beneficial when breeding for quantitative traits. FHB resistant varieties are needed for an effective and economical disease control strategy in wheat and GS can complement current breeding efforts to develop FHB resistant wheat varieties.
