BACKGROUND AND OBJECTIVES To compare the effectiveness of acupressure at P6 point and palonosetron in prevention of postoperative nausea and vomiting in patients undergoing laparoscopic tubal sterilisation. METHODS AND MATERIALS After obtaining institutional ethical clearance and patient consent, this study was conducted during the period of July 2015 to November 2015. Patients undergoing laparoscopic tubal sterilisation belonging to ASA 1 and 2 were included, and patients with hypertension, diabetes neurological diseases, peripheral vascular diseases, local skin diseases, patients on antiemetics and unwilling patients were excluded from the study. Randomisation done by sealed envelope method into two groups of sample size 25 each; group A (acupressure, at P6 point) and group B (palonosetron 0.075 mg IV). Acupressure band and Inj palonosetron were given just before the induction of anaesthesia. Episodes of PONV were recorded at 0-2 hours, 2-6 hours, 6-12 hours and evaluated separately as none, mild, moderate and severe. Rescue antiemetic was given to those who had episode of vomiting. Data analysed using Student 't' test and P value <0.05 considered to be significant. RESULTS Between two group comparisons no significant differences in terms of severity of PONV was observed and Group B showed no incidence of PONV. CONCLUSION Acupressure being non-invasive, non-pharmacological, inexpensive and better patient acceptability can be effectively used as an alternative for the prophylaxis of PONV. However, palonosetron was more effective than acupressure in preventing PONV.

To cater to the needs of air transportation, different wings for varying flight regimes for subsonic and supersonic were developed. However, the use of a particular wing is limited to only for a specific regime. Present work attempts to establish a relation between aerodynamic and electromagnetic energies associated with a wing. The understanding of aerodynamic and electromagnetic as a whole will lead to the idea of developing an autonomous wing. Experimental study was conducted on an unsymmetrical wing (with airfoil NACA 25115) with electric current flowing over its surface. The novelty of the work is that the results will be used for designing a wing that adjusts itself according to the flow conditions, eliminating the need for different wing for different flight regimes and flow conditions.

Background: Professional courses in medical education are highly stressful and students must be aware of the stress and the coping methods in the beginning of the course itself. Excessive, ill managed stress leads to depression and further suicidal tendency. Student suicides have become common news in today's era. It was reported that depression, anxiety and stress has negative impact on cognition. If the student has higher levels of stress, his academic performance decreases. This leads to increase in the stress further. Objective: The present study was undertaken to observe the association of depression, anxiety and stress with cognitive functions in female dental students. Methodology: A total of 34 female students studying second year BDS were included in the study after obtaining the written informed consent. Depression, anxiety and stress were assessed by using DASS 21 questionnaire. Cognitive functions were assessed by using digit symbol substitution test. Data was analyzed by SPSS 20.0. Pearson correlation coefficient was applied to observe the association between the variables.Results: For association of depression and cognition, the value of R is -0.5212. This is a moderate negative correlation. The value of R 2 , the coefficient of determination, is 0.2716. For association of anxiety and cognition, the value of R is -0.268. This indicates negative correlation. The value of R 2 , the coefficient of determination, is 0.0718. For association between the stress and cognition, the value of R is -0.1718, which indicates a negative correlation. The value of R 2 , the coefficient of determination, is 0.0295.Conclusion: There was negative correlation between the depression, anxiety and stress and cognitive functions. It is the need of time to increase awareness in students about stress and train them with coping methods to improve their academic performance and to limit student suicides in our country.
