OBJECTIVE:To investigate the effect of acupressure applied to UB60 and K3 acupuncture points in order to relieve the procedural pain caused by heel lancing blood sampling process in the term newborns.METHODS:The data were collected by using the Information Form and the Neonatal Infant Pain Scale.Acupressure applied for 3 min before heel lancing blood sampling in the newborns in the experimental group(n=31).No intervention was applied to newborns in the control group(n=32).RESULTS:A significant difference was found between mean scores of the newborns in the control and acupressure group in favor of the acupressure group in terms of heart rate during and after the procedure,oxygen saturation before,during and after the procedure,duration of crying during and after the procedure(P<0.05).It was found that there was a significant difference between groups in terms of Neonatal Infant Pain Scale mean scores during(P=0.001)and after the procedure(P<0.05),and the difference was found to be in favor of the acupressure group.CONCLUSION:As a result,acupressure was found to be an effective method in relieving pain caused by heel lancing blood sampling in newborns. 展开更多

[Objective] The paper was to study the expression pattern of specific genes during wool anagen and telogen stages and its significance to AoHan wool sheep breeding. [Method] Gene chip technology was used to detect the expression of epithelial genes in neck and groin during anagen and telogen stages in AoHan wool sheep. [Result] The expression of type Ⅰ IRS keratin genes KRT25, KRT26, KRT27 and KRT28 in neck and groin of wool sheep were statistically analyzed, and the result showed that the expression in neck during anagen stage was significantly higher than that in groin (The multiple was more than two times, P0.01). The expression changes of the genes during anagen and telogen stages were compared, and the results showed that the expression of all Type I IRS Keratin genes performed in groin showed significant decrease from anagen stage to telogen stage (P 0.05), the expression changes of other genes were two times higher, except KRT25 (LOC443079). [Conclusion] The result indicated that the expression of type Ⅰ IRS Keratin genes is closely related with the control of wool density in specific part and the whole wool development cycle. 展开更多

[Objective] The aim was to protect wild resource of Atractylodes lances and to provide technical guidance for industrialization of Atractylodes lances. [Method] The test-tube seedlings were produced from seeds of Atractylodis Lances. At the same time, the effects of 6-BA, NAA and KT on the proliferation of aseptic seedling was studied through the orthogonal test. Effect of NAA concentration on the rooting of aseptic seedling was studied through nine types of light substrate groups, which consist of peat soil, fine sand and cotton seed hull, and their effects on Atractylodes lances growth were studied on with orthogonal design. [Result] The culture medium suitable for the proliferation of the Atractylodes lances tube seedling was MS+6-BA 1.0 mg/L+NAA 0.4 mg/L+KT 0,4 mg/L. And the medium suitable for rooting was 1/2MS+NAA 0.5 mg/L. The optimal ratio of soil, riversand and cotton seed hull was 3:3:2. [Conclusion] The research selected optimum culture medium, rooting medium and ratio of substrate, which provided technical guidance for laboratorial preservation of germplasm resource of Atractylodes lances and industrialization of its seedling production. 展开更多

A double-parameter oxygen lance used in a 300 t converter was designed to improve the metallurgical performance. A small-scale measurement of the jet behavior was done using a computer controlled scanning system. The experimental data on the velocity distribution at the jet centerline, the contour map of the jet velocity, the deviation of the jet centerline, and the velocity distribution of the axial section were compiled. According to the results of the small-scale measurement, the double-parameter lance was also employed for a BOF experiment. The metallurgy inde- xes show that the metallurgical performance was highly promoted by use of the double-parameter lance. 展开更多

A three-dimensional computational fluid dynamics (CFD) model was developed to simulate a 150-t top-blown converter. The ef-fect of different lance heights on the cavity shape was investigated using the volume of fluid (VOF) method. Numerical simulation results can reflect the actual molten bath surface waves impinged by the supersonic oxygen jets. With increasing lance height, the cavity depth de-creases, and the cavity area, varying like a parabola, increases and then decreases. The cavity area maximizes at the lance height of 1.3 m. Under the three different lance heights simulated in this study, all of the largest impact velocities at the molten bath surface are between 50 m/s and 100 m/s. 展开更多

An improved mathematical model to describe the decarburization process in basic oxygen furnaces for steelmaking is presented in this work. This model takes into account those factors or parameters that determine the bath-oxygen impact area, such as the cavity depth, the lance height, the number of nozzles and the nozzles diameter. In the thermal issue, the model includes the targeted carbon content and temperature. The model is numerically solved, and is validated using reported data plant. The oxygen flow rate and the lance height are varied in the numerical simulations to study their effect on the carbon content and decarburization rate. 展开更多

"Big Sissy": The Queer Construction of Lance Loud

The continued popularity of reality television, and the release of the recent HBO film Cinema Verite--about the production of the first "reality show," An American Family (1973) --has resulted in renewed interest in the series and tangentially its other distinction--its portrayal of the first openly gay character on prime time television. Lance, the oldest of the Loud family children, is on film both flamboyant and effusive, but at the same time-through judicious editing--an asexual creature with no romantic or sexual relationships. This paper considers Lance in the context of Gay representation in media of the 1970s, and then explores the struggle of the filmmakers--and the Loud family themselves--to control and contain the public perception of Lance. The often vague and allusive comments by Lance's parents and even Lance himself suggest a character that is at once channing, witty, and vibrantly alive, yet also pretentious and deceitful. The final argument is that these complicit efforts to avoid controversy actually engender it, turning Lance Loud into a figure of mystery and conjecture ... and the undisputed star of the series. 展开更多

Single phase heat transfer analysis of water and R134a refrigerant (liquid phase) has been carried out using CFD (Computational fluid dynamics) approach for rectangular channel with smooth wavy fin. Colburnj factor and Fanning friction factorf are predicted for wavy fin. The correlations are developed at Reynolds number range of 100-15,000. The effect of fin geometry (fin spacing, fin height, wave height and wave length) on the enhanced heat transfer and pressure drops are investigated. Results show that there is no significant variation off factor for water and liquid R134a at constant Reynolds number. However variations inj factor were observed at constant Reynolds number. Colburnj factor and Fanning friction factorfcorrelations are proposed in terms of Re and geometry parameters (h/s, a/s, L/a) for water and liquid refrigerant R134a in the present study. Two separate equations are proposed for the low and high Re regions i.e. between Re of 100-1,000 and Re of 1,000-15,000. 展开更多

The water-air and Wood’s metal-air systems are modeled by means of Computational Fluid Dynamics to study the interaction between a liquid surface and an impinging air jet under the near field blowing conditions. The effect of the air jet velocity, the height of the injection lance, and the density of the liquid on the depth of the formed cavity is numerically studied. The CFD results of the cavity depth are compared with results previously reported by other authors. The emergence of the splashing phenomenon is predicted in terms of the critical velocity for each liquid-air system. Besides, the blowing number indicates that the drop generation rate is not significant for jet velocities below the critical velocity, and therefore neither the splashing is significant. 展开更多
