The Buddhist Church in Burma during the Pagan period, 1044-1287.

Buddhism as introduced from Ramannadesa to Pagan after Aniruddha's conquest of lower Burma, in A.D.1057 has been believed to be a pure Theravada form. Using largely epigraphic sources, this thesis proves this theory false. It also produces some evidences as to the presence of bhikkhuni - female ascetics - in the Order right up to the end of the Pagan dynasty whereas the tradition in Barma says that no woman was allowed in the Order since A.D.456. It also tries to solve the problem of the Ari whom the chronicles allege to practise jus primae noctis. Dr. C. Daroiselle connects them with Tantric Buddhism. The Ari sect or Arannavasi came into existence only in the second quarter of the thirteenth century and it was never officially suppressed. In fact it gained popular support right till the end of the Pagan dynasty. The orthodox group so tight assistance from Ceylon to arrest the sweeping success of Mahakassapa and his Arannavasi monks. This thesis also gives the architectural style of the period as described in the inscriptions. Slaves figured as an important social group in those days and therefore a chapter is entirely devoted to them. On the political aspect of the period, an almost completely new picture of the Pagan monarchy is given here. The names of the kings are in Old Burmese forms but identified. The administrative system of the period, is described as fully as possible. These form chapters one, two and three

The effectiveness of feature selection method in solar power prediction

This paper empirically shows that the effect of applying selected feature subsets on machine learning techniques significantly improves the accuracy for solar power prediction. Experiments are performed using five well-known wrapper feature selection methods to obtain the solar power prediction accuracy of machine learning techniques with selected feature subsets. For all the experiments, the machine learning techniques, namely, least median square (LMS), multilayer perceptron (MLP), and support vector machine (SVM), are used. Afterwards, these results are compared with the solar power prediction accuracy of those same machine leaning techniques (i.e., LMS, MLP, and SVM) but without applying feature selection methods (WAFS). Experiments are carried out using reliable and real life historical meteorological data. The comparison between the results clearly shows that LMS, MLP, and SVM provide better prediction accuracy (i.e., reduced MAE and MASE) with selected feature subsets than without selected feature subsets. Experimental results of this paper facilitate to make a concrete verdict that providing more attention and effort towards the feature subset selection aspect (e.g., selected feature subsets on prediction accuracy which is investigated in this paper) can significantly contribute to improve the accuracy of solar power prediction

Evaluation of tumor markers for the detection of hepatocellular carcinoma in Yangon General Hospital, Myanmar.

Levels of alpha-fetoprotein (AFP), its glycoforms AFP-L3 and AFP-P4, and proteins induced by vitamin K absence or antagonist-II (PIVKA-II) were determined in sera obtained from patients in Yangon General Hospital (20 with hepatocellular carcinoma (HCC), 29 with chronic liver diseases, including 3 with chronic hepatitis and 26 with cirrhosis of the liver, and 9 with other hepatobiliary diseases). Forty-five percent of the patients with HCC had serum AFP levels above 10,000 ng/ml, indicating that nearly half of the HCC patients were at an advanced stage of the disease. Thus, the AFP sensitivity was as high as 70% with 100% specificity for a cutoff level of 200 ng/ml. The sensitivity of AFP-L3 was 75% and a specificity 90% for a cutoff level of 15%. AFP-P4 showed a higher sensitivity of 80% and a similar specificity of 86% for a cutoff level of 12%. Combined evaluation of AFP-L3 and/or AFP-P4 increased the sensitivity to 90% with the same specificity of 86%, indicating that AFP-L3 and AFP-P4 are useful as adjuncts for diagnosis of HCC in the present population. PIVKA-II had a high sensitivity of 90%, although the specificity was lower than 45%, probably due to the low cutoff level, as some cholestatic patients were included in the control group.</p

A low temperature flat plate solar collector

The performance of a low temperature solar collector, which acts as an evaporator of a heat pump system, has been investigated. An experimcntal setup has been designed, fabricated and tested under the meteorological conditions of Singapore. Refrigerant 134a has been used in the experiments. Effects of various parameters have been considered. Results show that, with the increase in collector tube length, the dryness fraction of the fluid increases leading to an increase in the heat transfer coefficient between the tube wall and fluid. Results also show that collector is very sensitive to solar radiation. If solar radiation increases, the mass flow rate of fluid inside the collector increases, which increases the collector efficiency as more heat is absorbed. Collector efficiency increases with irradiation, reaches a maximum and then decreases. Collector efficiency, as high as about 0.85 was obtained, which could be attributed to the low temperature operation of the collector

Effect of seminal plasma removal, washing solutions, and centrifugation regimes on boer goat semen cryopreservation

Three experiments were carried out to improve semen quality during cryopreservation process. Total motility, forward motility, acrosome integrity, live spermatozoa, and normal spermatozoa were measured as semen quality. In Experiment 1, the effects of seminal plasma removal were analyzed by using two different extenders (GE and FE). The removal of seminal plasma gave higher and significant (P<0.05) effect in the total motility, forward motility, and live spermatozoa after cryopreservation. For two different extenders, however, the differences were not observed on the semen quality. In Experiment 2, three different washing solutions (namely, phosphate buffered saline, normal saline and Tris-based extender) were tested to evaluate the effects of semen quality after cryopreservation. Tris-based extender (TCG) conferred the highest (P<.05) sperm quality values in the total motility, forward motility, and live spermatozoa after cryopreservation. In Experiment 3, the effects of different centrifugation regimes (3000 × g for 3 min, 1600 × g for 10 min, 800 × g for 15 min) were evaluated on Boer semen quality. Semen quality parameters (namely, total motility, forward motility, acrosome integrity, and live spermatozoa) were significantly (P<.05) higher for cryopreserved spermatozoa centrifuged with 3000 × g for 3 min than the others. In conclusion, the removal of seminal plasma, washing solution TCG, and the use short-term centrifugation with a relative high g-force could contribute to the increased Boer semen quality after cryopreservation
