A numerical model for a bubble in nucleate pool boiling

Growth of a hemispherical bubble in nucleate pool boiling is analyzed in two stages using a numerical technique. In the first stage, growth of a hemispherical bubble in viscous medium on an isothermally heated surface is investigated neglecting the microlayer contribution. The results are compared with an analytical solution for homogeneous growth in a superheated medium, to other numerical results for heterogeneous growth in an inviscid medium, and to previous experimental work. The flow field and temperature distribution around the bubble are found to exhibit similarity for large times when an appropriate non-dimensionalization is used. The Jakob number (Ja), and subcooling number (Sb) are the only similarity parameters controlling growth in this asymptotic regime;In the second stage, growth of a hemispherical bubble is investigated including the analyses of a microlayer, the non-condensible gas inside the bubble and the temperature distribution in the heated surface. The temperature distribution in the fluid and in the solid, and the microlayer profile is found to be self similar for large time. The microlayer profile is almost triangular except at the tail point, where it is very steep. The famous bulk convection theory is found to be questionable. In accordance with experimental observations recorded in the literature, the growth of a bubble with a microlayer is found to be equal to that in homogeneous superheated medium for equal Jakob numbers. Pressure in the bubble is almost equal to the pressure of the environment except in the extremely short initial period. The bubble growth relation in saturated boiling isR = const Ja[superscript]3/4[over] Pr[superscript]1/4 √tfor 10 ≤ Ja ≤ 640, 0.26 ≤ Pr≤ 2.33, where Pr is the Prandtl number and the value of the constant is approximately 5. The contribution to bubble growth from the microlayer has been found to be 90% for Ja~eq 10, Pr~eq 2.5, 99% for Ja~eq 80, Pr ~eq 1, and as high as 99.8% for Ja~eq 320, Pr~eq 0.2. The flow field inside the bubble is investigated with and without the microlayer. The gas inside the bubble is proved to be at an uniform state in both the cases

Priority selection of agro-meteorological parameters for integrated plant diseases management through analytical hierarchy process

To understand the influence of agro-meteorological parameters to take decisions related to various factors in an integrated plant disease management, it becomes vital to carry out scientific studies on the factors affecting it. The different agro-meteorological parameters namely temperature, humidity, moisture, rain, phenological week, cropping season, soil type, location, precipitation, heat index, and cloud coverage have been considered for this study. Each parameter has been allocated the ranking by using a technique called analytical hierarchical process (AHP). The parameter priorities are determined by calculating the Eigenvalues. This helps to make decisions related to integrated plant disease management where the prediction of plant disease occurrence, yield prediction, irrigation requirements, and fertilization recommendations can be taken. To take these decisions which parameters are good indicators can be identified using this method. The parameters majorly contribute to plant diseases and pest management decision making while delivers minor contribution in irrigation and fertilizer management related decision making. The manual results are compared with software generated results which indicates that both the results correlate with each other. Therefore, AHP technique can be successfully implemented for prioritizing agro-meteorological parameters for integrated plant diseases management as the results for both levels are consistent (consistency ratio < 0.1)

Prosthodontic rehabilitation with Preci-Clix Overdenture system – A Case Report

Tooth loss has a negative impact on masticatory function, aesthetics, and self-image.  Fixed partial dentures, removable partial dentures, complete dentures, and implant-supported dentures can replace missing teeth, but it is not known whether they differ in their ability to reconstruct the masticatory force and preservation of residual bone ridge.  An overdenture is a complete or removable partial denture that has one or more abutment tooth or implants to provide a support.   Moreover the shortened crown also changes the crown to root ratio thus the reduced mobility of the tooth facilitate ridge preservation, improves the bone support.   Overdentures maintain proprioception of teeth and improve stability and retention.  Overdenture is preventive prosthodontics concept involving the multidisciplinary approach involving periodontic, endodontic & prosthodontics intervention. Prefabricated attachments are versatile and  provide considerable retention and stability.This case report of patient with few teeth remaining has been treated with overdenture supported with preci-clix overdenture attachments

Safety evaluation of seabuckthorn (Hippophae rhamnoides) leaves in Japanese quail

Aim: The present study was designed to evaluate the safety of seabuckthorn (Hippophae rhamnoides L. Elaeagnaceae) leaves added in the diet of Japanese quail. Materials and Methods: A total of ninety quail chicks were randomly divided into 2 groups and fed a standard quail chick mash added with or without 2% SBT leaf powder (Group SX), and a standard quail chick mash (Group CX, control) for 21 days. Six animals from each group were randomly sacrificed at 7, 14 and 21 day post feeding. Blood and tissue samples were collected for biochemical and histopathological studies.Results: The inclusion of SBT in quail diet did not affect the weekly body weights, clinical signs or mortality among the birds. The serum biochemical parameters like alanine transaminase, total protein, albumin, cholesterol and uric acid values in SBT treated group were found at par with those in the control group. Gross and histopathological studies of various internal organs such as liver, kidneys, heart, spleen, proventriculus, small intestine, bursa and thymus did not reveal any significant lesions in the tissue sections. However, proliferation of lymphoid tissue was a prominent finding noted in different lymphoid organs.Conclusion: In conclusion, the addition of seabuckthorn leaf powder at 2% level in the diet of Japanese quail was found to be safe and it can be used as a feed additive

COMPARATIVE STUDY OF EFFECT OF SWERTIA CHIRATA LEAF EXTRACT ON INDINAVIR TREATED RATS

Background: Indinavir is widely used for the treatment of human immunodeficiency virus (HIV) infection. It is known to cause hyperglycemia or insulin resistance and hyperlipidemia.Aim and Objectives: To study the effect of Swertia chirata leaf extract with metformin and pioglitazone on indinavir treated rats.Methods: Swiss albino rats were divided into five Groups of six animals each. All the groups (except control) were treated with indinavir 216 mg/kg (oral) for 15 days. Group I (control) received normal saline (oral) from day 8 to day 15, Group II received indinavir 216 mg/kg (oral), Group III received S. chirata plant extract 500 mg/kg (oral) from day 8 to day 15, Group IV received pioglitazone 4 mg/kg (oral) from day 8 to day 15, and Group V received metformin 36 mg/kg (oral) from day 8 to day 15. The biochemical parameters such as serum glucose, insulin, and lipid levels were measured on day 15. Results were analyzed using one-way analysis of variance followed by Bonferroni's multiple comparison test.Results: Indinavir (216 mg/kg) treated rats showed a significant (p<0.05) increase in glucose and insulin levels and also altered lipid levels. This indicates indinavir produces diabetic-like state in rats. S. chirata extract (500 mg/kg) decreases glucose and insulin levels and also improves lipid levels the effect is almost similar to metformin and pioglitazone.Conclusion: Indinavir causes elevated glucose, insulin and lipid levels, so care must be taken while prescribing indinavir for HIV patients. Treatment with S. chirata extract improved the altered glucose, insulin, and lipid profile in indinavir treated rats.Key words: Indinavir, Insulin resistance, Diabetes dyslipidemia, Glucose intolerance
