Sri Lanka: is it a mid-plate platelet?

Two observations suggest the possibility that Sri Lanka is acting as a small-mid-plate platelet moving very slowly within and relative to the larger Indian plate. First, sediments of the Bengal Deep-Sea Fan off the SSE continental margin are folded and uplifted in a manner similar to the deformation from front of accretionary prisms where thick sediment columns are passing into subduction zones. And second, subsidence rates in the area of presumed spreading or continuing stretching of continental crust, the Cauvery-Palk Strait-Gulf of Mannar Basin, have not decreased during the Cenozoic as would be predicted by an aborted rift or aulacogen model, but instead appear to have accelerated during the Neogene. Information available on other phenomena which re predicted by the model is at the present time inadequate for evaluation.

Thermal characterization of SOI CMOS micro hot-plate gas sensors

This work reports on thermal characterization of SOI (silicon on insulator) CMOS (complementary metal oxide semiconductor) MEMS (micro electro mechanical system) gas sensors using a thermoreflectance (TR) thermography system. The sensors were fabricated in a CMOS foundry and the micro hot-plate structures were created by back-etching the CMOS processed wafers in a MEMS foundry using DRIE (deep reactive ion etch) process. The calibration and experimental details of the thermoreflectance based thermal imaging setup, used for these micro hot-plate gas sensor structures, are presented. Experimentally determined temperature of a micro hot-plate sensor, using TR thermography and built-in silicon resistive temperature sensor, is compared with that estimated using numerical simulations. The results confirm that TR based thermal imaging technique can be used to determine surface temperature of CMOS MEMS devices with a high accuracy. © 2010 EDA Publishing/THERMINIC.

Effect of incubation period on plate count of raw ices and frozen fish

The total viable counts were estimated in one hundred and sixty five samples of raw, iced and frozen fish using incubation periods of 24, 48, 72 and 96h. For raw fish, 24h and for iced and frozen fish 48h incubation of the plates were found to be adequate. Variation between samples was significant at 1% level for raw iced and frozen samples.

Advantages of liquid nitrogen freezing of Penaeus monodon over conventional plate freezing

Liquid nitrogen frozen products are biochemically and organoleptically superior to conventional plate frozen products but beneficial effect of liquid nitrogen freezing over conventional plate freezing can exist only up to 59 days at a commercial storage temperature of -18°C.

Bunga rus bunga roides , A Record New to China ( Xizang AR) with a Note on Trimeresurus tibeta nus( Plate Ⅵ, lower)

1998 年在西藏墨脱县海拔1000 m 左右地方采到成年雌性环蛇1 号, 系我国新纪录。该蛇全长/ 尾长(mm) 1095/ 112 (尾尖断) 。通身背面黑褐色, 后3/ 4 有由背鳞白色点斑缀成的窄横纹约40 个; 腹面浅黑 色, 每隔3 或4 枚腹鳞有不规则的黄白色横斑。尾背有少数不完整的白色纹, 但尾腹面有7 条很明显的横斑。头 部斑纹与M. Smith (1943 : 410) 描述一致, 可能由于蛇龄较老而不清晰。背鳞通身15 行, 脊鳞略扩大; 腹鳞 233 , 尾下鳞35 (略低于文献记载的44～51 , 可能与尾尖断有关) , 除前端第三、四两枚成单外, 其余均成对。 没有颊鳞; 眶前鳞1 , 眶后鳞2 ; 颞鳞1 + 2 ; 上唇鳞7 (22223 式) ; 下唇鳞7 , 第一对在颏鳞后彼此相接, 前4 对 接前颔片; 前颔片大于后颔片, 后者后半介一小鳞。检查一侧, 除前沟牙及其预备牙外, 没有发现其他上颌齿。
