Impact of PowerPoint and Chalkboard teaching in Physiotherapy Undergraduates.

Background: A teacher's basic tool for displaying lectures are through blackboards, pegboards, bulletin boards, transparencies with an overhead projector (TOHP), PowerPoint presentation and walk and talk. Nowadays PowerPoint presentation is commonly used as it has ability to present the information in a clear, organized and simpler manner. The present study was carried out to find out the best method of teaching amongst the undergraduate Physiotherapy students. Objective: To compare the impact of the PowerPoint multimedia presentation and chalkboard in teaching by assessing the knowledge based on the marks obtained in the pretest and posttest. Methodology: 40 students were divided into two groups and a selected content-based lecture in pharmacology was delivered. For one group lecture was delivered using PowerPoint presentation, for second group using Chalkboard. Single - best Multiple Choice Questions [MCQs] paper was used for assessing the knowledge gained. The differences in the marks obtained in the two groups were analyzed Results: Students who attended the class on chalkboard obtained significantly higher score in single best MCQ examination compared to those students who attended the same content based lecture on the PowerPoint. Conclusion: The chalkboard method of teaching was found more suitable tool of teaching and learning than PowerPoint for small group

Free Radical Scavenging Potential of Mentha arvensis of South Gujarat: Evidence from In-vitro Assay

Present work was undertaken to evaluate efficacy of aqueous and methanol extracts Mentha arvensis leaves as free radical scavenger. The free radical scavenging activity was evaluated by nitric oxide scavenging method, hydrogen peroxide scavenging method and ferric thiocyanate method. The result of the studies was compared with the standard solution of Ascorbic Acid (Vitamin C) treated with same reagent. The results of all the studies showed significant free radical scavenging activity in both aqueous and methanolic extracts of Mentha arvensis and methanolic extract showed the highest free radical scavenging potential than aqueous extract.

Numerical Modelling of Regenerative Liquid Propellant Guns with Annular Piston

The development of regenerative liquid propellant guns (RLPGs) needs due consideration of numerous interdependent parameters that affect its performance. To help in this task, computer simulation was undertaken to predict internal ballistics of a conceptual liquid propellant gun. The expected pressure and other important parameters are documented which serve as an aid to the hardware, design of the regenerative liquid propellant guns

Preparation and Quality Control of the [153Sm]-Samarium Maltolate Complex as a Lanthanide Mobilization Product in Rats

Development of lanthanide detoxification agents and protocols is of great importance in management of overdoses. Due to safety of maltol as a detoxifying agent in metal overloads, it can be used as a lanthanide detoxifying agent. In order to demonstrate the biodistribution of final complex, [153Sm]-samarium maltolate was prepared using Sm-153 chloride (radiochemical purity >99.9%; ITLC and specific activity). The stability of the labeled compound was determined in the final solution up to 24h as well as the partition coefficient. Biodistribution studies of Sm-153 chloride, [153Sm]-samarium maltolate were carried out in wild-type rats comparing the critical organ uptakes. Comparative study for Sm3+ cation and the labeled compound was conducted up to 48 h, demonstrating a more rapid wash out for the labeled compound. The effective and biological half lives of 2.3 h and 2.46h were calculated for the complex. The data suggest the detoxification property of maltol formulation for lanthanide overdoses

Investigation of Ignition of Liquid Propellant in Reservoir in Regenerative Liquid Propellant Gun Trials

It is important to understand the internal ballistic processes for the development of regenerative liquid propellant guns (RLPGs). A 30 mm RLPG test fixture was developed and firing trials were conducted to study the performance of the gun. During the trials, sometimes, combustion ignition in the reservoir took place resulting in substantial damage to the injection piston. This paper highlights the possible causes of this combustion and offers suggestions. regarding improvement in the design. An elaborate instrumentation set-up which could pinpoint the specific conditions leading to failures is suggested

An Eco-benign Synthesis of AgNps using Hydroalcoholic Extract of Brassica oleracea var. italica Plenck : Anticancer Response against Human Breast Cancer Cells MCF-7

Breast Cancer is the second foremost reason of Cancer mortality in females globally. The conventional treatments available for Breast Cancer include surgery yet they are related to serious side effects that have moved the worldwide focus towards Complementary and Alternative Medicines (CAM). One of the emerging strategies has been the use of plant extracts for synthesizing metal nanoparticles (such as gold and silver) for anticancer applications. The objective of this study is to reflect the current availed study on green synthesis of silver nanoparticles (AgNps) with its future prospects to treat Breast Cancer. The development of eco-friendly and reliable techniques for silver nanoparticles synthesis is a vital initiative in the area of nanotechnology. Brassica oleracea var. italica Plenck Leaves Extract (LE) prepared by maceration process and silver nanoparticles of LE prepared by using biological reduction method. Female rats were divided into 5 groups, Group-I served as Positive Control and received normal saline. Group-II served Negative Control (Tumor Bearing) and was treated with single dose of MCF 7. Breast Cancer Cells (1.7 mg/pellet). Group-III served Standard Control (Tumor Bearing) treated with Paclitaxel 40 mg/Kg. Group-IV served test and treated with LE 400 mg/Kg, Group-V served test and treated with LENP 400 mg/Kg respectively about 21 days and on 21th day blood samples were collected for Hematological Parameters and Feed and Water Consumption, Body Weight Determination and Organ Weight were estimated. These discoveries infer that the synthesized Silver nanoparticles utilizing green nanotechnology could be a perfect methodology to battle malignant growth and irresistible ailments.
