This data article aimed to investigate the quality of surface water in Kalingarayan Canal for heavy metal pollution, Tamil Nadu. Eight heavy metals like Fe, Cu, Mn, Cr, Zn, Cd, Pb, and Ni were analyzed in the water, for a period of three years, spanning the time frame between January 2014 to December 2016. Eight stations were selected along the Kalingarayan Canal, and water samples were collected on a monthly basis from these stations. The pH of the samples was in the alkaline state (6.88–8.90), whereas conductance was in the range of 394–4276 µs/cm. The average concentration of heavy metals in the surface water ranges from 0.040 to 10.75, 0.030 to 0.890, 0.02 to 0.91, 0.00 to 1.96, 0.00 to 0.01, 0.00 to 0.053, 0.01 to 0.12 and 0.110 to 3.40 mg/L for the metals Fe, Mn, Zn, Cu, Cd, Ni, Pb and Cr respectively. The dominance of various heavy metals in the surface water follows the sequence: Fe > Cr > Cu > Zn > Mn > Pb > Ni > Cd respectively. The canal is affected by anthropogenic activities and industrialization in terms of heavy metals.

Background: Research is a scientific process that gathers and analyses information in order to increase our understanding of a specific topic or problem. Research can provide answers to previously unknown questions, filling knowledge gaps and changing the way healthcare professionals work. Therefore, present study aims to assess attitude towards research in nursing students of Rajasthan, India. Method: Descriptive survey research design was selected to conduct the study. Modified Attitude Towards Research (ATR) scale used as research instrument. 373 nursing students from various nursing colleges of Rajasthan were included as participants in the study through random online Googledoc survey. Results: In the present study 75.10% nursing students have not attended any conference, seminar, webinar regarding research. For the total modified ATR scale statements, 49.56% (184.86) nursing students were agreed while 35.92% (134.02) nursing students were not agreed and 14.56% (54.34) nursing students remained neutral with the statements regarding attitude towards research. On the basis of scoring of the ATR scale, around half of the nursing students, 54.42% (203) had positive attitude level, 41.83% (156) had neutral attitude level while only 3.75% (14) had negative attitude level regarding research. Findings revealed that there was significant association between level of attitude regarding research among nursing students with demographic variable like how many conferences, seminar, webinar attended regarding research. Conclusion: The study concluded that there is strong need for educational interventions like conference, seminar and webinar besides regular curriculum for nursing students regarding research as they are future health care providers. Building a positive attitude towards research will help nurses for more scientific approach and providing nursing care on evidence based practices.

Research purpose. This study aimed to determine the EMG analysis of forehand topspin using different ball materials.  Materials and methods. For the purposes of this study, seven male university-level table tennis players who were right-hand dominant players (age 21.1 ± 2.4 years, height 162.6 ± 6.8 cm, mass 61.8 ± 3.2 kg) with at least 6 years of playing experience were selected. The selected participants were physically active and had no physical injuries. The study was approved by the research committee. Pectoralis Major (PM), Deltoid Anterior (DA), Latissimus Dorsi (LD), Biceps Brachii (BB), Extensor Carpi Radialis (ECR), Flexor Carpi Radialis (FCR) muscles were selected for the electromyographical study. One of the EMG signals variable Root Mean Square was measured in all muscles, through which the maximum muscle involvement was evaluated. For each assessed muscle and both ball materials, the mean value of Root Mean Square EMG signals was computed. For descriptive statistics, minimum, maximum, mean, and standard deviation were used, and a t-test was used as a statistical technique.  Results. The level of significance was set at 0.05. Results of the study showed no significant difference in EMG variable Root Mean Square between celluloid and poly plastic ball material on selected muscles.  Conclusions. We conclude that the biceps brachii and extensor carpi radialis are important muscles for the forehand topspin because they are responsible for flexion of the arm and work strongly in the action of gripping in the performance of quick forehand spin strokes.

Introduction: Patients encountered with fracture shaft and neck femur require some anaesthesia or pain relief to allow radiological, orthopedic and other procedures to be performed. Regional anaesthesia is the most widely used an aesthetic technique for orthopedic procedures in lower limbs.Fascia iliaca blocks provide a safe, cheap and effective form of pain relief for patients with neck of femur fractures. Animal studies have proven the combination of dexmedetomidine with ropivacaine to be safe and neuro-protective. Fascia iliaca compartment block which involve femoral nerve, lateral cutaneous nerve of thigh and obturator nerve. This study is designed to compare Fascia Iliaca Compartment Block under ultrasound guidance with ropivacaine and ropivacaine plus dexmedetomidine positioning during spinal anesthesia in femur fractures. Material and methods: This study was conducted at Mahatma Gandhi hospital and Mathuradas Mathur hospital, Jodhpur during January 2019–January 2020. 60 Patients admitted in Orthopaedic ward age group 21-60 yrs. of both sex were the source of data. Patients undergoing elective surgery for fracture femur (neck of femur and intertrochanteric) under SAB were included in the study. We divided the cases into 2 groups of 30 each, as GROUP R: Patients were received 30 ml 0.50% Inj. ropivacaine + 2 ml Normal saline with a total volume of 32 ml in unilateral FICB. GROUP RD: Patients were received 30 ml 0.50% Inj. Ropivacaine + 2 ml Inj. Dexmeditomidine (0.5mcg/Kg) with a total volume of 32 ml in unilateral FICB. Standard protocol followed to administering regional anaesthesia. All data were collected and analysed with the help of suitable statistical parameters. Results: Our study results in that Fascia Iliaca Compartment Block with combination of ropivacaine and dexmedetomidine is more efficacious than ropivacaine alone for positioning during spinal anaesthesia in surgery for fracture femur. Key words: Spinal Anaesthesia, Fascia Iliaca Compartment Block, Ropivacaine, Dexmedetomidine.
