Hindu Iconography in Bagan

( Myint Myint San ) 부산외국어대학교 동남아지역원 2014 Suvannabhumi Vol.6 No.1

This study focuses on the iconography of Hindu deities in Bagan period. As a country in Southeast Asia, Myanmar received her culture from Indianized culture. As aforesaid,sailors, traders, and settlers brought with them Brahmanism and Buddhism into Myanmar. A possibility is that local chiefs or the rulers invited Brahmans to conductcoronations, weddings, and burials in Brahmanical rites as they will much impressed by the Brahmanical thoughtsand beliefs. Accordingly, Brahmanic icons as objects of worship are found quite in number of places, especiallyin Thaton, Bago, Vesali, Sriksetra, Bagan and Kawgoon. Apart from Buddhist iconography, the Brahmanic icons of various sects can be found in Bagan. Brahmanic deities are illustrated with Buddhist painting, which is a characteristic of Baganreligious iconography. Most of the scenes on Hinduism are to be found in NatlaungKyaung, Nanpaya and Shwesandaw Pagoda. Myanmar people, however, knowingly or unknowingly ignore some features of Indian deitiesand eventually the iconsare found in various places in Bagan.

<P><B>Abstract</B></P> <P>We report the synthesis of water-soluble and environmentally friendly fluorescent carbon dots (CDs) using the renewable resource lignin as a precursor, which is a waste emitted from pulp and paper industries and lignocellulosic biofuel production, using a compressed liquid CO<SUB>2</SUB> antisolvent method followed by carbonization and chemical oxidation with an acid mixture (H<SUB>2</SUB>SO<SUB>4</SUB>:HNO<SUB>3</SUB> =1:3, v/v) at 90°C for 8, 16, and 24h. The as-synthesized CDs emitted bright yellow fluorescence (FL) under argon laser excitation at 458nm with excitation-wavelength-independent and excitation-wavelength-dependent FL emission characteristics. Moreover, the CDs exhibited excellent stability in a highly concentrated NaCl solution, photostability with pH-dependent FL emission activities, and cellular imaging capability with very low cytotoxicity. Notably, the FL emission intensities of the as-synthesized CDs increased with longer reaction times, indicating high degree of oxidation on the CD surface and consequently, high quantum yield of 13% was achieved. Therefore, the as-synthesized CDs can be used as promising fluorescent probes for bioimaging applications <I>in vitro</I> and <I>in vivo</I>.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Water-soluble fluorescent carbon dots (CDs) synthesized from kraft lignin. </LI> <LI> CDs exhibited pH-dependent fluorescence (FL) emission and high salt/photo stability. </LI> <LI> FL emission intensities increased with longer reaction times. </LI> <LI> A high quantum yield of 13% resulted in the CDs synthesized for 24h. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

<P><B>Abstract</B></P> <P>Carbon nanoparticles with hierarchical micro/mesoporous structure were developed from a commercial kraft lignin using a facile, one-pot green technology of a compressed liquid CO<SUB>2</SUB> antisolvent treatment, followed by thermostablization and carbonization processes. The as-synthesized carbon nanoparticles were systematically characterized by investigating the surface properties of morphology, particle size, and chemical states with FESEM, HRTEM and XPS, respectively; surface areas and porous structures with BET analyzer; crystalline state with XRD and Raman spectroscopy; chemical features with FTIR; and elemental compositions with an elemental analyzer. The results indicated that the carbon nanoparticles fabricated from the smallest quasi-spherical lignin nanoparticles contained high nanocrystalline and amorphous carbons levels. The enhanced phenolic, carbonyl, and carboxylic functional groups on the particle surface promoted the dispersibility of the particles in deionized water. The size and morphology of the lignin precursor particles significantly affected the fabrication of the carbon nanoparticles by carbonization. The experiment suggested that such dispersible and porous carbon nanoparticles could be applicable in the fields of energy, biotechnology, and environmental pollution control.</P> <P><B>Highlights</B></P> <P> <UL> <LI> We have developed hierarchically porous carbon nanoparticles from kraft lignin. </LI> <LI> The carbon nanoparticles’ surfaces contain enhanced oxygen-containing functional groups. </LI> <LI> They have high surface areas and show good dispersibility in deionized water. </LI> <LI> The size and morphology of lignin precursors are important in the carbonization step. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Influence of membrane surface properties on the behavior of initial bacterial adhesion and biofilm development onto nanofiltration membranes

Myint, Aye Aye,Lee, Wonil,Mun, Sungmin,Ahn, Chang Hoon,Lee, Seockheon,Yoon, Jeyong Taylor Francis 2010 BIOFOULING -CHUR- Vol.26 No.3

<P> In order to investigate biofouling problems, the fundamental behaviors of initial bacterial adhesion and biofilm development on four different nanofiltration (NF) membranes were evaluated using Pseudomonas aeruginosa PAO1 as a model bacterial strain. Initial cell adhesion was considerably higher on an aromatic polyamide-based NF membrane with a hydrophobic and rough surface, whereas cell aggregation on a polypiperazine-based NF membrane with a relatively hydrophilic and smooth surface was lower. Moreover, significant differences in the structural heterogeneity of the biofilms were observed among the four NF membranes. This study shows that the surface roughness and hydrophobicity of a membrane play an important role in determining initial cell adhesion, aggregation and favorable localization sites for colony formation. In addition, it was found that biofilm development was strongly influenced by the surface morphology of a membrane.</P>

Myint, Si Lhyam,Shimogiri, Takeshi,Kawabe, Kotaro,Hashiguchi, Tsutomu,Maeda, Yoshizane,Okamoto, Shin Asian Australasian Association of Animal Productio 2010 Animal Bioscience Vol.23 No.9

In this study, to examine genetic variability within a breed and genetic relationships between populations/breeds, we genotyped 606 birds from seven Japanese native chicken breeds at seven polymorphic loci of egg white proteins and compared those with Asian native chicken populations and commercial breeds. Genotyping of the Japanese native breeds showed that ovalbumin, two ovoglobulins and ovotransferrin were polymorphic, but ovomacroglobulin, ovoflavoprotein and lysozyme were monomorphic. The proportion of polymorphic loci ($P_{poly}$) and average heterozygosity ($\bar{H}$) within a population ranged from 0.286 to 0.429 and from 0.085 to 0.158, respectively. The coefficient of gene differentiation ($G_{ST}$) was 0.250 in the Japanese native chicken breeds. This estimate was higher than that of Asian native chicken populations ($G_{ST}$ = 0.083) and of commercial breeds ($G_{ST}$ = 0.169). Dendrogram and PCA plot showed that Satsuma-dori, Jitokko, Amakusa-daio and Hinai-dori were closely related to each other and grouped into Asian native chickens and that Tsushima-jidori, Nagoya and Chan (Utaichan) were ramified far from other Japanese native chicken breeds. The egg white protein polymorphisms demonstrated that the population differentiation of the seven Japanese native chicken breeds was relatively large.

Impact of bleaching on subcritical water- and Formosolv-pretreated tulip tree to enhance enzyme accessibility

Myint, A.A.,Kim, D.S.,Lee, H.W.,Yoon, J.,Choi, I.G.,Choi, J.W.,Lee, Y.W. Elsevier Applied Science 2013 Bioresource technology Vol.145 No.-

A novel method was developed for fractionating cellulose microfibrils from forest residue (tulip tree sawdust) to enhance cellulose digestibility, particularly at minimum enzyme loadings. This method involved three main stages: selective hemicellulose solubilization by subcritical water (SCW) pretreatment, delignification of the SCW-pretreated solids using the Formosolv process, and deformylation/bleaching of the cellulose pulp with alkaline hydrogen peroxide solution. This process produced nearly 98% white cellulose microfibrils with 23-fold higher conversion to glucose as compared to the raw substrate after 72h of enzymatic hydrolysis. This study showed that cellulose swelling had the greatest effect on the enzymatic hydrolysis efficiency of delignified pulp obtained by the Formosolv process.

One pot synthesis of environmentally friendly lignin nanoparticles with compressed liquid carbon dioxide as an antisolvent

Myint, Aye Aye,Lee, Hun Wook,Seo, Bumjoon,Son, Won-Su,Yoon, Junho,Yoon, Tae Jun,Park, Hee Jeong,Yu, Jihyun,Yoon, Jeyong,Lee, Youn-Woo The Royal Society of Chemistry 2016 GREEN CHEMISTRY Vol.18 No.7

<P>Nanoparticles from commercial kraft lignin were developed using a facile, one pot green technology of a compressed CO2 antisolvent. N,N-Dimethylformamide (DMF) was employed as an organic solvent to prepare the lignin solution. The effects of various process parameters: temperature, pressure, solution flow rate and initial solution concentration, on the product yields, morphology, size, size distribution, surface area and textural properties of the particles were investigated by FESEM, HRTEM analyses and BET analyzers, and their formation mechanisms were deduced by the solubility behavior of lignin with liquid CO2 and DMF in the operating system. Moreover, the quality of lignin nanoparticles were elucidated by ATR-FTIR, XPS, XRD, DSC, TG/DTA and UV-vis measurements. This study showed that as the temperature and lignin concentration increased, and the pressure and solution flow rate decreased, the degree of particle aggregation/coalescence and the size increased along with the broader size distribution. In particular, the coalescence of particles was strongly influenced by the operational pressure, and even more significant with the increasing temperature. As a result, uniform, quasi-spherical nanoparticles with a mean particle diameter of 38 nm were obtained at 280.2 K, 15.0 MPa, and 0.06 kg h(-1) of the solution flow rate and 5.3 wt% of the initial lignin concentration. Besides, the lignin nanoparticles have a relatively high BET surface area (nearly 92 m(2) g(-1)) which primarily consisted of mesopores, and exhibited higher UV absorbing and dispersion stability, enhanced solubility, and homogeneous thermal degradation activity as compared with the raw lignin. Noteworthily, their biodegradable and biocompatible character may render them a candidate for applications in cosmetics, health and drug delivery systems.</P>

Resolved: Uniting Nations in a Divided World

Myint Zan (사) 이준국제법연구원 2022 Journal of East Asia and International Law Vol.15 No.1

The eighth Secretary-General of the United Nations Mr. Ban Ki-moon, after serving 10 years retired on January 1, 2018. His memoirs, “Resolved Uniting Nations in A Divided World” were published in 2021. Ban Ki-Moon is the only UN Secretary-General who was born and brought up in a country that not only was a victim of an invasion but also for the first time in the history of the UN, the Organization itself was directly involved in countering the invasion. Ban Ki-moon’s memoirs narrates articulately and compassionately many issues that divide the world. The efforts and ‘resolve’ of the eighth UN Secretary-General to solve, ‘resolve’ and to improve the human condition (so to speak) is reflected in the optimistic sentiment expressed in the concluding sentence of his book: “[t]ogether our mission is possible.”
