134 Zin Moe Moe IRRIGATION SCHEDULE OF ACTUAL VERSUS ESTIMATED EVAPOTRANSPIRATION ON VEGETABLE SOYBEAN (GCIE MA L.) AGS - 292 Scheduling of irrigation to crops is essential for efficient utilization of available water, saving of input and enhancing yield. The study was aimed to investigate the efficient water use based on soil moisture measuring methods and to evaluate the interactions between actual and estimated water reuirement on vegetable soybean field of VFRDC. According to soil analysis, the soil type is sandy loam soil. Soil sample was collected daily for measuring actual water reuirement of vegetable soybean by Gravimetric method. The estimated evapotranspiration (ET0) of Blaney & Criddle was compared to CROPWAT method. The climate data had also recorded such as temperature, humidity, wind and sunshine hours. Crop water reuirement was measured by the method of Blaney & Criddle (1950) which is suitable method for the most of crops in Myanmar. A comparison was made between estimated crop water consumption versus actual water consumption. The result of this study showed that in young stage of crop, actual crop water consumption and estimated crop water consumption were almost eual level, but when plants became mature, the actual crop water consumption was higher than the estimated one. Based on this investigation, it must be concluded that the temperature based method for estimated crop water reuirement, Blaney and Criddle method, is the most suitable in Myanmar for irrigation schedule. 2018
135 Soe Soe Aye BIOACCUMULATION OF HEAVY METALS IN THE MUSCLE OF SOME COMMERCIAL FISHES FROM HLAING RIVER SEGMENT OF SHWE PYI THAR TOWNSHIP, YANGON REGION* Analysis of some heavy metals in the muscle of some commercial fishes collected from Hlaing River in Shwe Pyi Thar Township, Yangon Region were conducted during April 2015 to March 2017. Suspected toxic metals from industrial sewages such as Al, Cr, Cd, As, Ni, Hg and Pb were analysed in detail. The majority of tested heavy metals were found to be high concentration in the muscles of all studied commercial fish species. The concentration of Al, Cr, Cd, As, and Hg in the fish muscles were exceeding the permissible limits of FAO/WHO (1992) standard for human consumption. Condition factors of studied fishes were negatively correlated with the concentration of heavy metals in their muscles. High bioaccumulation factor value were observed in all studied fish species, so as tested heavy metals were accumulated by fish showing long term exposure of heavy metals to fish in its surrounding. The bioaccumulation factors of demersal fishes were higher in most of the tested metals than benthopelagic fishes. Bioaccumulation factors of all tested heavy metals were found to be higher in the dry season than other seasons. Daily consumption in large amount of studied fish species captured from the Hlaing River may cause health problems if bioaccumulation continues in the same rate without taking effective management for pollution in the Hlaing River. 2018
136 Ei Ei Ko SPECIES DIVERSITY OF BUTTERFLIES IN NYAUNG SHWE ENVIRONS, SOUTHERN SHAN STATE A total of 4358 butterflies representing 74 species, confined to 52 genera and five families were recorded during the study period from June 2014 to May 2015 at Nyaung Shwe environs. Among the families recorded namely, Papilionidae (10 species), Pieridae (14 species), Nymphalidae (35 species), Lycaenidae (9 species) and Hesperiidae (6 species), the highest number of species was recorded in Nymphalidae and lowest in Hesperiidae. At Nyaung Shwe environs the highest diversity indices value was found in November while the lowest indices value was occurred in June at both Site A and B. The 74 butterfly species and their host plants recorded thrive well in both the study sites. It is suggested that these butterflies should be conserved for further studies on butterflies. 2018
137 Lei Lei Aye APPLICABILITY OF FISH SCALES NANOBIOMATERIALS IN HARD TISSUE ENGINEERING d out by burning the fish scales at different temperatures. These biomaterials were proved to be nano-sized hydroxyapatite by using X.R.D.(xray diffraction), F.T.I.R.(fourier transform infrared spectroscopy) and S.E.M.(scanning electron microscope). Purity of the sample was confirmed by T.G.A.(thermo-gravimetric analysis), protein content and Ca/P weight ratio. Porosity in the sample was calculated by image J software. Toxic heavy metal was not detected by mineral analysis. Evaluation of hardness of F.S.HAp-Glass Powder-GIC Composite was done by Mitutoyo micro-hardness testing machine. Hardness of pure Glass Ionomer (Japan) was found to be 3.5 Mohs while that of F.S.HAp-Glass Powder-GIC Composite was 4 Mohs. As the hardness is very near to teeth and skeletal tissue, it is suitable for substitution in tooth defect area. 2018

The study was conducted in Myeik area, Tanintharyi Region from May 2015 to October 2016. The research designed was based on field study. The field work was conducted three times in the study period, in each study site. A total of 11 species were recorded representing two tortoise species and nine freshwater turtle species in Myeik area. Among the recorded species 18 of soft shell and 82 of hard shell were observed. The values of diversity index for three study sites indicated that the condition of these sites may be perfect habitat for the turtle species. During investigation, illegal shell trade was encountered in Tanintharyi and Palaw Township. 2018
139 Kyaw Lin Zaw NATURE AND CHARACTERISTICS OF GOLD MINERALIATION AT MODI TAUNG GOLD DEPOSIT, YAMETHIN TOWNSHIP, MANDALAY REGION* The ModiTaung area is located 370 km to the north of Yangon. The segment of gold mineralization is of interest as it is the first reported gold deposits of slate-hosted mesothermal quartz-gold veins (orogenic gold deposit) in Myanmar. This slate belt consists of the argillaceous rocks namely Mergui Group (Late Palaeozoic age) and which is largely intruded by many plutons. The deposit is hosted within three major vein systems. They are made up of several veins which are spatially grouped into their respective systems. Vein textures are mostly of three types; book-andribbon texture, laminated to stylolitic texture and massive texture. Mineralized shear veins tend to follow three trends within brittle-ductile regimes and occur at the centre of the shear zone (C vein) or oblique to the shear zone boundary. Book and ribbon vein textures provide evidence that mineralization took place during D2 within NNE trending shear zones. Pyrite chemistry indicates two main episodes of gold mineralization: syngenetic gold precipitation in Py1 and an epigenetic gold mineralization in Py2 and Py3. Py1 is interpreted to be of syngenetic/diagenetic origin because of its higher Ag, Ni, V contents and the ratio Au/Ag is less than 1. Py2 and Py3 are of hydrothermal origin as they have low levels of Ni, V, and Ag with Co/Ni ratio and Au/Ag more than 1. Evidence of pulsed hydrothermal mineralizing fluids is also consistent with the presence of cobalt and nickel zoned micro-bands in the pyrite structure.gold in Py1 could have been remobilized by circulation of later magmatic and metamorphic fluids and concentrated elsewhere enhancing the gold content in later generations of pyrite (Py2 and Py3). 2018
140 Khaing Khaing San A NEW OCCURRENCE OF THE MIDDLE DEVONIAN UNIT IN THE LASHIO AREA, NORTHERN SHAN STATE A new occurrence of the Middle Devonian Unit equivalent to the Padaukpin Limestone in Wetwin-Padaukpin area is recognized for the first time in the lower part of the Maymyo Formation, Lashio area, northern Shan State. It exposed as isolated outcrops only at two localities in Lashio area. The unit mainly composed of from base to top; (1) medium- bedded, grey to dark grey calcitic limestone intercalated with thin-bedded, black shale with abundant recrystallized gastropods (Quarry near the Hseing Hkai car-road, N 22? 53 36 and E 97?40 51); (2) medium-bedded, ligh grey to buff, argillceous limestone with buff to black shale and siltstone containing abundant crinoid stems, cystoid plates and brachiopods and (3) medium-bedded, light grey to grey, calcitic limestone and buff coloured argillaceous limestone interbedded with buff to black shale and siltstone comprising abundant tabulate and rugose corals (along the car-road from Lashio to Muse at mile post 5-6 furlong, N 22? 54 02 and E 97?4208). This unit is also the sandwiched unit in the Maymyo Formation and laterally passed into the dolomite or dolomitic limestone. The age of the unit exposed at the Lashio area is defined by the strong faunal evidences such as gastropods: Muchisonia sp., oonema sp. and Euromphalus sp. and important tabulate and rugose coral species: Favositesgoldfusi, Alveolites sp., Coenites sp., Aulocystics sp., Stringophyllum sp., rypophyllum sp., Temnophyllum sp., Acanthophyllum sp., Peripaedium sp., Cyathophyllumsp. and abundant Calceolasandalina. Calceolasandalina which are known as a typical Middle Devonian (Eifelian) species in Myanmar, Europe, USSR, Asia and Australia. It is a more complete succession of the faunal assemblage with Middle Devonian age and slightly different in lithology and faunal content with the type section of the Padaukpin Limestone. 2018
