Published: February 2018

Corrosion inhibitors of 2-isopropyl-5-methylphenol and its derivatives has been elucidated by means of density functional theory at B3LYP/6-31G(d) level of theory. Effect of electron donating and withdrawing groups such as NH2, SH, CHCH2, CH3, OH, CHO, COOH, F and NO2 on the corrosion inhibitor of 2-isopropyl-5-methylphenol derivatives also have been studied. The quantum chemical parameters such as the frontier orbital energies (EHOMO), ionization potential (I), electron affinity (A) and electronegativity (χ) are closely related to the corrosion inhibition efficiency (IE %) of 2-isopropyl-5-methylphenol derivatives. The presence of electron donating groups increase IE % values meanwhile electron with drawing groups reduce IE % values. The enhancement of IE % follows NO2 < CHO < COOH < SH < F < CH3 < CHCH2 < OH < NH2. Electron donating NH2 group gives 96.38 % of IE %, pure 2-isopropyl-5-methylphenol IE % = 82.70 %. In contrast, electron withdrawing NO2 group gives IE % only 68.66 %. This theoretical study would have a significantly contribution for accelerating corrosion inhibitor experimental to gain optimum results.

Authors: Trivana Linda , Sugiarti Sri , Rohaeti Eti
Published: February 2018

In this study, zeolite was synthesized from kaolin which was founded from Bangka Belitung as the starting material. Meanwhile, sodium silicate was used as silica source. Zeolite is material with many benefits, such as become an adsorbent. Kaolin has been used as starting material due to high content of silica and alumina, i.e 35 - 50 %. Zeolite was prepared by hydrothermal synthesis process, by mixing the metakaolin which was produced by calcination of kaolin at 700 °C for 6 hours, with sodium silicate and NaOH. The NaOH was used to activate the major components of Si and Al in the kaolin.The hydrothermal process was conducted at 100 °C for 24 hours with various concentrations of NaOH, i.e 1.5 N and 2.5 N. The NaOH concentration might determine the type of zeolite obtained. To improve the nature as adsorbent, zeolites modified into zeolit/TiO2. The addition of TiO2into the prepared zeolit aimed to produce a material with capability as adsorbent-photocatalyst. The result of research found that the addition of NaOH 1.5 N produced zeolite NaP1. Meanwhile, the addition of NaOH 2.5 N produced the NaP1 zeolite, zeolite X, and faujasite. The composite of zeolit/TiO2has ability on adsorption-photocatalytic as it was proven by methylene blue degradation under ultraviolet light.

Published: February 2018

The addition of garlic powder to gelatin from chicken claw waste was potentially developed as a natural preservative in food, especially for meat. Preparation of gelatin/garlic biocomposite was performed in three stages: synthesis of gelatin from chicken claw, garlic powder preparation as allicin source and preparation of biocomposite gelatin/garlic. The preparation of dry biocomposites was done by weighing the gelatin and garlic powder in weight ratio of 1 : 1 and 1 : 2 (w/w) in the total mass of 0.75 grams. For wet biocomposite preparation, the mixture of the powder was solved in 5 mL of lactic acid 2 %. Functional groups of gelatin, garlic and biocomposite were analyzed by fourier transform infrared spectroscopy (FTIR). The antibacterial activity of biocomposite against Staphylococcus aureus were tested using disc diffusion method. This test was performed on garlic powder, solvent and gelatin/garlic biocomposites powder in the ratio of 1 : 1 and 1 : 2 in 2 % lactic acid solvent. The biocomposite with a weight ratio of gelatin : garlic of  1 : 1 had the optimum diameter of inhibition zone. The effectiveness of biocomposite gelatin/garlic as natural preservative applied in meat was also physically studied by organoleptic analysis. Organoleptic analysis through the hedonic test was conducted on the parameters of color, smell, and texture of gelatin/garlic biocomposites-coated meat. The results showed that the addition of garlic can increase the effectiveness of gelatin as a natural preservative of meat for four days stored in closed packaging at room temperature.

Special Issue on SATREPS Myanmar Project: Construction of Myanmar Disaster Response Enhancement System and Industry-Academia-Government Cooperation Platform
Authors: Meguro Kimiro , Hideomi Gokon
Published: February 2018

This special issue summarizes the main results of the first half of the five-year SATREPS project in Myanmar. SATREPS stands for “Science and Technology Research Partnership for Sustainable Development” and it is supported by the Japan International Cooperation Agency (JICA) and the Japan Science and Technology Agency (JST). The title of our project is “Construction of Myanmar Disaster Response Enhancement System and Industry-Academia-Government Cooperation Platform.” Ours is the first SATREPS project in Myanmar and Yangon Technological University (YTU) is our main counterpart institute and relevant organizations mainly national and local governments are collaborating as strategic partners.

In Myanmar, rural and urban development has been progressing rapidly and on a large scale, and the expansion of urban population coupled with climate change has increased the risk of disaster to a critical level, especially in Yangon, Myanmar’s largest city. By monitoring changes in the urban environment, such as the topography, ground, buildings, and infrastructure, we seek to lower the level of risk. Our project will improve the disaster management system, plan and response capability, based on an evaluation of disaster vulnerabilities. Considering floods including tidal wave problems and earthquakes as the target hazards, we aim to contribute to the development of precise regional development plans and disaster management measures by identifying disaster risks in advance, and we will support the Myanmar government in strengthening its disaster response capabilities.

We plan to set up a system by which industry, academia, and the government collaborate to promote the understanding of research content, to continue research activities, and to implement research results in Myanmar. We hope that our activities in the SATREPS project will become an ideal model for solving issues in urban development and disaster management, and that the project will also contribute the other Asian countries.

Published: February 2018

In Myanmar, defects and possible deformation were reported in many long-span suspension bridges. The current state of bridge infrastructure must be inspected, so that deterioration can be stalled and failure can be prevented. A 3D laser scanner, specifically the terrestrial laser scanner (TLS), has demonstrated the ability to capture surface geometry with millimeter accuracy. Consequently, TLS technology has received significant interest in various applications including in the field of structural survey. However, research on its application in large bridge structure remains limited. This study examines the use of TLS point cloud for the measurement of three deformation behaviors at the Pathein Suspension Bridge in Myanmar. These behaviors include tower inclination, hanger inclination, and deflection of bridge truss. The measurement results clearly captured the deformation state of the bridge. A comparison of the measurement results with available conventional measurements yielded overall agreement. However, errors were observed in some areas, which could be due to noise and occlusion in the point cloud model. In this study, the advantages of TLS in providing non-discrete data, direct measurement in meaningful unit, and access to difficult-to-access sections, such as top of towers or main cables, were demonstrated. The limitations of TLS as observed in this study were mainly influenced by external factors during field survey. Hence, it was suggested that further study on appropriate TLS surveying practice for large bridge structure should be conducted.

An important criterion for conducting an accurate seismic hazard analysis and assessment is the compiling of a representative and completehistorical seismic catalog for the region of interest. This paper describes the procedure to assemble a full earthquake events catalog for Syria from the years 37 AD to 2011 AD. The procedure starts with improving the quality of the compiled full catalog by eliminating manmade events by choosing a cutoff magnitude of 2.5; and by eliminating the potential aftershocks and afforeshcks using an appropriate declustering method. To examine the quality of the resultant seismic catalog (after eliminating artificial, aftershock and afforeshok earthquake) the magnitude of completeness (MC) was calculated and the distribution of MC with time showed an overall good quality of the adopted complete catalog. The adopted complete seismic catalog is then used to generate peak ground acceleration hazard maps for 475, 1000 and 2475 years return periods. The study also concludes that to accommodate for the quiescence of the DSFS and potential undetected buildup and release of seismic energy it is important to introduce 1000 and 2475 years return periods seismic hazard maps especially in the design of important structures.

Kubis bunga merupakan sayuran sehat yang banyak diminati konsumen. Dalam peningkatan produksi tanaman sayuran, khususnya kubis bunga yang perlu diperhatikan adalah kualitas benih. Oleh karena itu dilakukan kegiatan penelitian untuk menghasilkan benih kubis bunga yang bermutu. Penelitian bertujuan untuk mengetahui konsentrasi pupuk Boron yang tepat dan teknik penanaman untuk peningkatan perbenihan kubis bunga. Penelitian dilakukan di Kebun Percobaan Berastagi mulai dari bulan Januari sampai Oktober 2014. Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) pola faktorial dengan empat ulangan. Faktor pertama adalah dosis pupuk Boron (B0 = tanpa pupuk Boron, B1 = 5 kg/ha, B2 = 10 kg/ha, B3 = 15 kg/ha, B4 = 20 kg/ha, B5 = 25 kg/ha). Faktor kedua adalah teknik penanaman (N1 = tanpa naungan, N2 = menggunakan naungan). Hasil penelitian menunjukkan bahwa pemberian Boron 15 kg/ha dapat meningkatkan jumlah cabang, jumlah polong, jumlah dan bobot benih per tanaman, serta persentase benih tumbuh per tanaman pada perbenihan kubis bunga. Pemakaian naungan dapat meningkatkan jumlah tangkai, jumlah polong, jumlah dan bobot benih per tanaman pada perbenihan kubis bunga.

Cauliflower is a nutritious vegetable that highly demanded by consumers. The yield of cauliflower is very much effected by the seedling quality. This justifies the importance of studying how to produce a good quality of cauliflower seedling. The objective of the study was to determine the exact concentration of Boron fertilizer and to identify the most appropriate planting technique in producing cauliflower seedlings. The study was conducted in Berastagi Experimental Garden from January to October 2014. A randomized complete block design (RBD) was used with four replications. The first factor was the dose of Boron fertilizer (B0 = without Boron fertilizer, B1 = 5 kg / ha, B2 = 10 kg / ha, B3 = 15 kg / ha, B4 = 20 kg / ha, B5 = 25 kg/ha). The second factor was planting techniques (N1 = without shade, N2 = with shade). The results suggest that the use of 15 kg/ha Boron increases the number of branches, number of pods, number of seeds and seed weight per plant, as well as percentage of seed emergence per plant. The use of shade also increases the number of branchs, number of pods, number of seeds, and seed weight per plant.

‘Language shades everything’: Considerations and implications for assessing young children from culturally and linguistically diverse backgrounds
Authors: Keary Anne , Kirkby Jane
Published: February 2018

Assessment of young children from culturally and linguistically diverse backgrounds holds the potential to provide important insights into learning. Two researchers investigated an Allied Health screening program that was conducted in three kindergartens in a disadvantaged area of outer Melbourne, Australia. Drawing on narrative inquiry methodology the researchers explored the understandings given to the screening program by Allied Health professionals and Early Childhood teachers and administrators in relation to CALD children. From analysis of interview and focus group data, insights were gained into the way the screening program employed culturally and linguistically responsive practices. Flexible assessment practices, acknowledgement of children’s linguistic abilities and family- centred practice emerged as key strategies to enhance Early Childhood assessment programs that cater to the strengths and needs of young children from CALD backgrounds. However, the investigation demonstrated that issues of equity and compromise are heightened as policy and practice diverge on how to implement these strategies. In conclusion, it is argued, that targeted professional learning could assist Early Childhood teachers to negotiate this divergent space.

In-silico Studies of Isolated Phytoalkaloid Against Lipoxygenase: Study Based on Possible Correlation
Authors: Khan Haroon , Zafar Muhammad , Den-Haan Helena , Perez-Sanchez Horacio , Kamal Mohammad Amjad
Published: February 2018

Aim and Objective:

Lipoxygenase (LOX) enzymes play an important role in the
pathophysiology of several inflammatory and allergic diseases including bronchial asthma, allergic
rhinitis, atopic dermatitis, allergic conjunctivitis, rheumatoid arthritis and chronic obstructive
pulmonary disease. Inhibitors of the LOX are believed to be an ideal approach in the treatment of
diseases caused by its over-expression. In this regard, several synthetic and natural agents are under
investigation worldwide. Alkaloids are the most thoroughly investigated class of natural compounds
with outstanding past in clinically useful drugs. In this article, we have discussed various alkaloids of
plant origin that have already shown lipoxygenase inhibition in-vitro with possible correlation in in
silico studies.

Materials and Methods:

Molecular docking studies were performed using MOE (Molecular
Operating Environment) software. Among the ten reported LOX alkaloids inhibitors, derived from
plant, compounds 4, 2, 3 and 1 showed excellent docking scores and receptor sensitivity.

Result and Conclusion:

These compounds already exhibited in vitro lipoxygenase inhibition and the
MOE results strongly correlated with the experimental results. On the basis of these in vitro assays
and computer aided results, we suggest that these compounds need further detail in vivo studies and
clinical trial for the discovery of new more effective and safe lipoxygenase inhibitors. In conclusion,
these results might be useful in the design of new and potential lipoxygenase (LOX) inhibitors.

Published: February 2018

Freshwater algae can tolerate wide range of environmental stress and grow naturally in mixed
communities. In the present study diversity of algae has been studied in some suburban water
bodies near Lucknow, which revealed the occurrence of 32 genera and 40 taxa under four phyla -
Cyanophyta, Chlorophyta, Bacillariophyta and Euglenophyta. It is observed that heavy
anthropogenic activities and low water level in late summer resulted in accumulation of pollutants
which affected the algal species composition. The polluted water with high conductivity and
total dissolved solids (TDS) showed the dominance of Cyanophyta and Bacillariophyta whereas

Supreme Court, Institutional Change and Authoritarian Regimes: Argentina and Brazil (1964-1985)
Authors: Del Río Andrés
Published: February 2018

Over the past century, Latin America experienced important political changes. Many countries in the region –such as Argentina and Brazil– faced both harsh authoritarian governments and flourishing democracies. In these two countries, the constant changes of political regimes also brought important institutional changes in the Judicial Power, particularly in the Supreme Court. This paper will analyze the institutional change of the Supreme Court from a comparative perspective. By looking at the cases of Argentina and Brazil, we will review the trajectory of both High Courts in a violent political moment (1964 - 1985). In particular, we will analyze the ways in which these courts were altered in moments of authoritarian regimes. Our analysis will focus on the means used to alter each Court and the objectives of these modifications. Although the cases share some similarities, it is fundamental to remark that each case has its particular trajectory. To understand this, we will analyze the institutional transformation of the High Courts in Argentina and Brazil from a historical perspective, always keeping in mind the violent contexts in which these changes tend to occur.
Análisis de la creación y modificación del consejo de la magistratura de la República Argentina
Authors: Hunger Pablo Ignacio
Published: February 2018

El presente documento dará cuenta de las modificaciones normativas (constitucionales e infraconstitucionales) que sufrió el Consejo de la Magistratura del Poder Judicial de la Nación con el objeto de justificar el impacto negativo que han tenido sobre la administración de justicia de la República Argentina. Dichas modificaciones han alterado el equilibrio republicano establecido explícitamente en la Constitución nacional, restringiendo el derecho de acceder a la justicia de cada argentino. El análisis que se efectuará a continuación se centrará en el plenario del Consejo de la Magistratura para explicitar cómo la injerencia del poder ejecutivo colisiona contra el equilibrio de poderes, resultando de ello una justicia dependiente.

Authors: Reyes Chávez Johan David
Published: February 2018

Antecedentes y Objetivos: En 1996 las pteridofitas en Honduras estaban representadas por 109 géneros y 651 especies. Sin embargo, aunque no hay un catálogo reciente que refleje la diversidad actual de este grupo, han sido descubiertas en territorio hondureño nuevos registros y especies. Con el objetivo de aumentar el conocimiento del grupo, se presenta el primer registro de Draconopteris draconoptera para la flora de Honduras.Métodos: Como parte de inventarios florísticos en sitios arqueológicos dentro del núcleo de la Reserva del Hombre y Biosfera del Río Plátano (RHBRP), se colectaron diversos especímenes de plantas, entre ellos una especie no reportada previamente, identificada por el especialista R. C. Moran y confirmada posteriormente, usando claves taxonómicas.Resultados clave: El helecho encontrado en la RHBRP, Draconopteris draconoptera, representa un nuevo registro de un género monoespecífico para la flora de Honduras, expandiendo su distribución conocida más hacia el norte.Conclusiones: Se observa la necesidad de continuar investigando y actualizar el catálogo de pteridofitas de Honduras, con base en cambios taxonómicos recientes y el descubrimiento de nuevas especies y registros en el territorio hondureño desde su última actualización.

Published: February 2018

This paper elaborates on the current condition of the public library, focusing on the one in Alor Gajah. One of the main issues faced by the public library today is the lack of visitors. Scholars suggest that it is crucial to integrate the users’ perspectives into the building design as the sense of attachment of the user to a place can greatly affect their attitude towards the spaces perceived. The study aims to investigate the new approaches in the design of a library, to upgrade it as a social interactive space, particularly in Alor Gajah, Melaka.

AbstractIn this two-part work, nanostructures formed in a three-step process of metal-assisted chemical etching of silicon are investigated. In the first part (present publication), the process of the chemical deposition of a layer of self-assembled silver nanoparticles on the surface of a silicon wafer (the first stage of metalassisted chemical etching) is studied. This layer, on the one hand, serves as a catalyst for the subsequent etching of silicon, and, on the other hand, represents a kind of mask for the formation of a certain topology of the emerging Si nanowires. The morphology of the obtained 40- to 60-nm-thick silver nanoparticle layers is investigated by scanning electron microscopy. The spectral dependences of the ellipsometric angles Ψ and Δ are measured using spectroscopic ellipsometry (λ = 250–900nm), and the complex dielectric function of the silver nanolayers is determined from these spectra. The dielectric function features a characteristic plasmon resonance peak in the ultraviolet spectral range. The study of the optical properties of Si nanofilament layers which form during the early stages of metal-assisted chemical etching will be reported as the second part of this work in a separate publication.

AbstractThe results of studying the effect of various conditions of heat dissipation on heating and temperature distribution in components of concentrator photovoltaic modules are reported. The modules based on Fresnel lenses and triple-junction solar cells InGaP/GaAs/Ge mounted on copper and steel heat sinks are studied. In order to determine the thermal characteristics, we use a method, which makes it possible to measure the temperature of the p–n junctions in the solar cells under laboratory conditions upon the simulation of thermal processes arising in the course of operation of the module under typical conditions. Further, the above temperature is used to calculate the value of the thermal resistance for a system consisting of a solar cell and the surrounding medium. The thermal processes in the module are simulated by transferring current through the solar cells in the forward-bias direction. The value of heating of the solar cells is determined by comparing the forward-voltage drops measured at the time of its rapid application or switching-off under various conditions of heat removal. The conditions of heat removal are varied using the generator’s air flow.

AbstractThe results of experimental examination of galvanomagnetic properties of thin bismuth films subjected to plane tensile strain resulting from the difference in thermal expansion coefficients of the substrate material and bismuth are presented. The resistivity, the magnetoresistance, and the Hall coefficient were studied at temperatures ranging from 5 to 300 K in magnetic fields as strong as 0.65 T. Carrier densities were calculated. A considerable increase in carrier density in films thinner than 30 nm was observed. This suggests that surface states are more prominent in thin bismuth films on mica substrates, while the films themselves may exhibit the properties of a topological insulator.

AbstractAn improved parameter-free method of joint Argand diagrams was used to expand the permittivity spectrum of gallium arsenide in a region of 19–26 eV into 12 bands of optical transitions with determining their maximum and half-width energies, as well as the oscillator strengths. The values of oscillator strengths of the obtained bands lie within an interval from 0.0009 to 0.06. In the regions of 19.2–21.3 and 24–26 eV, the permittivity spectrum was preliminarily calculated on the basis of experimental reflectance spectra with the use of the Kramers–Kronig integral relation method. The nature of the obtained transition bands is suggested in terms of the band-to-band and exciton transitions.

AbstractThe temperature dependences of the heat capacity ( C _ p ) and the thermal conductivity (κ) in the temperature range from 300 to 773 K of polycrystalline gadolinium sulfide samples (γ-GdS_ y ) with the deviation of the composition from the integer stoichiometric were studied. It was found that the thermal conductivity of gadolinium sulfides decreases monotonically and reaches 0.74 W/(m K) at T = 773 K for the composition y = 1.479, which is much lower than for the known single-crystal samples. The influence of morphological defects (boundaries of crystallites and dislocations) on the intensity of scattering of phonons is studied. It has been established that ceramic samples of gadolinium sulphides have a large heat capacity and a lower thermal conductivity, in comparison with monocrystalline samples of the same composition.

AbstractA comparative study of the dielectric properties and electric polarization of multiferroics GdMn_2O_5 and Gd_0.8Ce_0.2MnO_5 has been carried out in the temperature range 5–330 K. The polarization properties in the ferroelectric state that forms due to a charge ordering and exchange striction have been studied at T ≤ T _C = 30 K. The properties of the restricted polar phase separation domains formed in the crystals containing ions Mn^3+ and Mn^4+ have been studied, too. These domains exhibit the electric polarization in the temperature range from 5 K to some temperatures T _f ≫ T _C. Such a high-temperature polarization is due to the frozen superparaelectric state of the restricted polar domains.

AbstractSingle heterostructures of type II n ^+-InA s/n ^0-InAs_0.59Sb_0.16P_0.25, based on an intentionally undoped epitaxial layer with an electronic type of conductivity are obtained by metalorganic vapor phase epitaxy (MOVPE). In the heterostructure, a transition layer of modulated composition is formed near the heterointerface in the bulk of the quaternary solid solution. The existence of a radiative recombination channel due to the presence of localized hole states in quantum wells formed in the transition layer near the heterointerface is shown. It is demonstrated that the maximum of the intensity of the electroluminescence spectrum of the heterostructure under study is rearranged when a forward external bias is applied. The results of this study can be used in the development of tunable light-emitting diodes operating in the midinfrared range of 2–4 μm.
