No full text
We report herein a new palaeomagnetic study on the Middle Permian and Middle Triassic limestones from Shan State of eastern Myanmar, aiming to resolve the spatial location of the Sibumasu Terrane during the collision of tectonic blocks in Southeast Asia and to constrain the timing of convergence between the Sibumasu Terrane and Indochina Terrane. Based on the rock magnetic and palaeomagnetic experiments, three stable characteristic remnant magnetizations are recognized from limestone specimens of Middle Permian and Middle Triassic age. The characteristic Component C of the Middle Permian limestone passed the fold test at 95% confidence level, indicative of a pre-folding origin. The mean direction of this component is D = 10.7°, I = 17.9° (κ = 130.3, α
95
= 10.8°) before and D = 13.7°, I = −25.3° (κ = 1894.9, α
95
= 2.8°) after tilt correction, corresponding to a palaeomagnetic pole at 254.1°E, 53.2°N (A
95
= 1.7°). This suggests that the Sibumasu Terrane was placed at a palaeolatitude of ~13.0°S during the Middle Permian. The Component C separated from the Middle Triassic samples also passed the fold test with a mean direction of D = 207.3°, I = −8.3° (κ = 12.9, α
95
= 6.2°) before tilt correction and D = 205.6°, I = −33.5° (κ = 27.1, α
95
= 4.2°) after tilt correction, corresponding to a palaeomagnetic pole at 187.3°E, 65.8°N (dp/dm = 2.7°/4.8°). This implies that the Sibumasu Terrane was located at a palaeolatitude of ~18.3°N during the Middle Triassic. Based upon the detailed palaeomagnetic analysis, this study supports the view that the collision of the Sibumasu Terrane and Indochina Terrance occurred during or before the Middle–Late Triassic times.

Calculation of Metal Pollution Index and Enrichment Factor in Sodic Soil from Salt Production Area
No full textIn the present paper, the sodic soil samples were collected from the salt production area of Thakhauttaw, Hanlin, Sataung Gyi and Paline, Shwebo District, Sagaing Region. These samples were studied on the elemental analysis using the energy dispersive x ray fluorescence EDXRF spectroscopy. In order to evaluate the contamination status of metals, assessment indices such as metal pollution index MPI and enrichment factors EFs have been calculated by using the metal concentrations from the EDXRF results. The values of metal pollution index MPI for all samples were less than 1. This indicating the sodic soil was no significant of metal pollution. The results of enrichment factors show that Ca and Mn considerable enriched levels in the soil. According to health physics point of view, the overall study suggests that the sodic soil from salt production area were not metal contaminated and long term consumption cannot be cause potential health risks to consumers.

Health risk aof heavy metals in some vegetables and fishes yielded around Taungthaman Lake
No full textThe purpose of this paper is the determination of health risk assessment of the some heavy metals concentration in the human body contributed by crop, vegetables and fishes. The metal pollution indexes, the daily intake of some heavy elements in all measured samples are presented. Moreover, the health risk index are calculated and presented. The heavy metal concentrations in all measured samples, which are collected from this study site and analyzed in 2015 are compared with the safe limit of FAO/WHO recommended value. It was found that risk of Cromium, Aresnic, Cadmium and Mercury is observed by consumption of analyzed foodstuffs, because of the fact that the health risk indexes for these heavy metals are greater than one
General Aung San – the Father of Burma’s Independence
No full textThe author presents General Aung San (1915-1947) as a dedicated fighter for independence and through his complicated biography outlines the crucial period of Burma’s history: the end of the British colonial rule. The paper also presents the cultural differences that complicated Burmese-British relations.
It appears that Aung San’s nationalist spirit had been already shaped in his childhood. He became famous as a student leader during his education at Rangoon University in the 1930’s. In 1938 he had been elected the Secretary General of the most significant nationalist force: the Association We-Burmese (Do-Bama Asi-Ayone). On the one hand he was involved in lawful political activity, on the other he tried to acquire weapons by all possible means to start an armed struggle for independence. He created numerous political organizations of different political orientation (including the Communist Party of Burma). Eventually he arrived in Japan, where he received military training. In 1941, with the help of Japanese agents, he was able to create the Burma Independence Army in Thailand, which entered Burma together with the Japanese troops in 1942.
His co-operation with the Japanese forces was tortuous and painful, but he served as the Minister of War in their puppet Burmese Government. When it became obvious that the Allies will win, he established contacts with them and in August 1944 founded the Anti-Fascist Organisation. On March 27, 1945 he started an anti-Japanese uprising to help the British forces entering the country. At the end of the war his relations with the British authorities were very complex: the civil administration wanted to arrest him and bring him to justice as a war criminal, but the military commanders appreciated his help and wanted to collaborate with him and his Burmese forces. The second approach prevailed and in 1946 he headed the Burmese colonial government under the British Governor. In January 1947 he successfully negotiated Burma’s independence in London. The famous Panglong Agreement reached with the leaders of national minorities in February constituted another success of his. In April his party won the majority in the elections to the Constitutional Assembly and Aung San started his work on the constitution. In July, during feverish preparations for independence, he was assassinated together with six other members of the government. U Nu, his old friend and political successor completed his task of building up the independent state. The present military junta constitutes the first Burmese government, which does not respect General Aung San much owing to the prodemocratic activities of Aung San Suu Kyi, his daughter

Assessing Elite Capture in “Engaging Women and Men Farmers in Participatory Research and Extension” Project: A Case Study in Magway Township
No full textThe study was carried out to assess the existence of elite capture in the Australian Centre for Inter-national Agricultural Research (ACIAR) projected villages. The survey was conducted in three projected villages (Pho Lay Lone, Nat Kan and Aung Myay Kone), Magway Township in June 2017. The data on household livelihoods were collected from 40 households (20 projected households selected by the ACIAR project with predetermined criteria and 20 non-projected households selected randomly) from each of three projected villages to assess their original human, natural, financial, social and physical cap-itals. It was found that almost all of the natural, social and physical capitals of the projected households were higher than those of the non-projected households in Pho Lay Lone and Nat Kan villages. In com-parison the status of human and financial capitals of the projected households was superior to those of the non-projected households in Nat Kan village. It indicated that the project have chosen the households whose livelihood were better than those of the remaining households in Pho Lay Lone and Nat Kan vil-lages. Therefore, elite seemed to capture the project in Pho Lay Lone and Nat Kan villages. In Aung Myay Kone village, most livelihood assets under human, natural, financial, social and physical capitals were not significantly different between the projected and non-projected households. Therefore, elite capture could not be observed in the selection of project households in Aung Myay Kone village. It indi-cated that smallholders had little chance to get the benefits of the project in Pho Lay Lone and Nat Kan villages while the benefit of the project could cover the whole community in Aung Myay Kone village. Therefore, it can be suggested that there should be a proper analysis on the livelihoods of farm house-holds in the target areas before choosing the projected participants to prevent the elite capture
Dentoskeletal Changes of Skeletal Class III Malocclusion with Severe Facial Asymmetry after Orthognathic Surgery: Case Report
No full textCraniofacial asymmetry is expressed as the difference in size between two parts of the face. It is originated by a discrepancy in size and position between the cranial base and the maxilla, between the cranial base and the mandible, or between the maxilla and the mandible. When the craniofacial asymmetry is severe and the patient has completed growth, the indicated treatment is performed in conjunction with orthodontics and orthognathic surgery, traditional approach or surgery first approach. A 24 year-old woman had chief complaints of mandibular protrusion and facial asymmetry. Extraoral examination indicated mandibular deviation to the right side, severe facial asymmetry, and a concave profile. Orthognathic surgical treatment plan was Lefort I osteotomy and two-piece maxillary osteotomy to correct the posterior crossbite. Concomitant surgical procedure for the mandible was bilateral sagittal split osteotomy to correct facial asymmetry and mandibular protrusion. After orthognathic surgery followed by postsurgical orthodontic treatment reveals skeletal Class I and acceptable facial aesthetics with Class I occlusion. According to this case report, double jaw surgical procedure including maxillary and mandibular movements is indicated for the treatment of severe facial asymmetry and skeletal Class III malocclusion
Association between HLA-B* 15:02 and carbamazepine induced severe cutaneous adverse drug reactions in Myanmar
No full textGenetic predisposition to carbamazepine (CBZ)-induced Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) had been reported in several Southeast Asian populations, but not in Myanmar. Previous studies had so far reported more than 70% of CBZ-induced SJS/TEN cases
positive for HLA-B*15:02 allele.1-4 Myanmar, as the second largest country in Southeast Asia with a population of 54.5 million, has high HLA-B*15:02 carrier frequency in its general population (27.3- 49.1%).5,6
Elemental Concentrations and Risk Assessment of Heavy and Toxic Metals in Some Instant Foods
No full textEnergy Dispersive X-rays Fluorescence (EDXRF) technique was used to analyze
the elemental concentrations of some heavy and toxic metals in some instant food
samples. For all measured samples, the mean concentrations of Cr, Mn, Fe, Co, Ni, Cu,
Zn, and As are within their respective safe limit except Cd and Hg. It was found that the
mercury concentration in instant noodles samples is significantly the highest among the
instant food samples. No risk was found for the elements of Cr, Mn, Fe, Co, Ni, Cu, Zn,
and As. But, the elements, Cd and Hg, were found to cause the risk to the consumers by
consuming the instant foods
