The present study evaluates the performance of original and location specific calibrated Hargreaves equation （HARG） with the estimates of Food and Agricultural Organization （FAO） Penman Monteith （PM） method for higher altitudes in East Sikkim, India. The results show that the uncalibrated HARG model underestimates ET0 by 0.35 mm day^-1 whereas the results are significantly improved by regional calibration of the model. In addition, this paper also presents the variability in the trajectory associated with the climatic variables with the changing climate in the study site. Non- parametric Mann-Kendall （MK） test was used to investigate and understand the mean monthly trend of eight climatic parameters including reference evapotranspiration （ET0） for the period of 1985 - 2009. Trend of ET0 was estimated for the calculations done by FAO PM equation. The outcomes of the trend analysis show significant increasing （p ≤ 0.05） trend represented by higher Z-values, through MK test, for net radiation （Rn）, maximum temperature （Tmax） and minimum temperature （Train）, especially in the first months of the year. Whereas, significant （0.01 ≥ p ≤0.05） decreasing trend in vapor pressure deficit （VPD） and precipitation （P） is observed throughout the year. Declining trend in sunshine duration, VPD and ET0 is found in spring （March - May） and monsoon （June - November） season. The result displays significant （0.01≤ p ≤0.05） decreasing ET0 trend between （June - December） except in July, exhibiting the positive relation with VPD followed by sunshine duration at the station. Overall, the study emphasizes the importance of trend analysis of ET0 and other climatic variables for efficient planning and managing the agricultural practices, in identifying the changes in the meteorological parameters and to accurately assess the hydrologic water balance of the hilly regions.展开更多

We injected cyanoacrylate adhesive into the specimens to create a marker, and scanned them using a miniature OCT probe. The localization of these markers was assessed in the OCT images. Then we compared the OCT-imaged morphology with the corresponding histological section, guided by the cyanoacrylate adhesive markers. We prepared a second set of experiments using nylon sutures as markers. RESULTS： The OCT image of the esophageal specimen has a clear five-layered morphology. First, it consisted of a relatively less reflective layer; second, a more reflective layer; third, a less reflective layer; fourth, a more reflective layer; and fifth, a less reflective layer. Comparing the OCT images with marked histological sections showed that the first layer corresponded to stratified squamous epithelium; the second to lamina propria; the third to muscularis mucosa; fourth, submucosa; and fifth, muscularis propria with deeper structures of the esophageal wa CONCLUSION： We demonstrated that the OCT image of the normal esophageal wall showed a five- layered morphology, which corresponds to histological esophageal wall components.展开更多

Therefore, accounting regulation research spans over three spheres of enquiry： （1） an accounting focus of standard-setting; （2） a cultural analysis in an empirical context; and （3） the use of a research methodology drawn from Anthony Giddens＇ structuration theory. In such approach, accounting regulation research analyzes the accounting regulation actors drawing upon the cultures in their standard-setting actions and interactions, referring to Giddens＇ three structural properties of meaning, power, and morality. The integration of these three spheres of enquiry is not entirely original. A few prior studies have similar combinations： Although they stress the uses and consequences of accounting systems in producing and reproducing organizational culture and negotiating meaning at the organizational level, this paper chooses the research approach of contextual analysis of accounting systems at more macro-societal and cultural levels. This different research interest and design provides this paper with its distinguishable characteristic from the prior similar studies.展开更多

Methods： From February 2009 to February 2010, 12 patients with closed non-fracture mallet fingers were treated by buried purse-string suture. The rupture tendons were sutured by purse-string suture with an atraumatic needle, and the knots were buried under subcutaneous tissue. External fixator was used at the extension position of the finger every night within three weeks after operation. Results： All patients were followed up for 6-12 months, mean 7 months. According to the Patel＇s evaluation criteria, 2 cases （17%） obtained excellent results, 7 good （58%）, 2 fair （17%） and 1 poor （8%）. The overall rate of the cases with excellent and good outcomes was 75%. Conclusion： Buried purse-string suture is an easy and effective way to treat mallet finger deformities, with no serious postoperative complications or no need for reoperation.展开更多

But in clinical practice we found that in some fracture cases, the damage to soft tissues is not as severe as ＂destructive injury＂ indicates, whereas comminuted fractures still cannot show the severity of bone damage. Therefore we proposed a new term ＂destructive fractures＂ after combining the definition of destructive injury with typical clinic cases. Destructive fractures refer to the fractures whose osseous tissues are damaged too seriously to be repaired, but soft tissues, nerves and veins are less severely injured and can be repaired. From the year 2001 to 2010, 75 cases of destructive fractures were admitted in our department. According to whether the fractures interlinked with the external environment, together with the fracture sites, they were divided into 6 types： al type, closed diaphysis destructive fracture; a2 type, open diaphysis destructive fracture; b1 type, closed joint-involved destructive fracture; b2 type,open joint-involved destructive fracture; cl type, closed mixed destructive fracture; c2 type, open mixed destructive fracture. Corresponding clinical treatments were conducted for each type.The new classification criterion of destructivefracture is simple and practical and thus can be used as an important guide to make reasonable treatment plans for destructive fractures.展开更多
