Prevalence of Carpal Tunnel Syndrome Among Workers Engaged in Manufacturing Industry

Carpal Tunnel Syndrome is a symptomatic compression neuropathy of the median nerve at the level of the wrist/hand characterized physiologically by evidence of increased pressure within the carpal tunnel and decreased function of the nerve at that level. It is characterized by patients as producing numbness, tingling, hand & arm pain, loss of hand and pinch strength and muscle dysfunction. CTS is caused by physical occupational activities, such as repeated and forceful movements of the hand and wrist and also by doing work in awkward posture. Present work is focused on studying CTS on the workers engaged in Railway Workshop Kalka. The study is conducted on 90 workers comprising of all men (mean age of 47.9±9.02 years). The objective of present work is to study the probability of occurrences of Carpal tunnel syndrome of the workers engaged in Railway Workshop Kalka by comparison of potential CTS symptoms. This is done by conducting the appropriate health surveillance, data collection using surface electromyography (sEMG) on Abductor Pollicis Brevis (APB) muscle. First of all designing of health surveillance form is done followed by data collection. Statistical analysis using ANOVA, Fisher’s Exact test. ANOVA was used to analyze the Body Mass Index (BMI) data obtained from the health surveillance. F value calculated came out to be 0.110 for the degree of freedom (3, 16). This calculated F value is less than the critical value (3.24). So the BMI considered in present study significantly contribute in the occurrence of the carpal tunnel syndrome. To observe the occurrence of potential CTS symptoms among Slender and Obese workers, Odd ratio test was performed which reveals that obese workers has approximately 1.5% times greater risk of having CTS than that of slender worker. Fisher’s exact test is used on all the three type of pinch strengths i.e. Tip pinch, key pinch and palmer pinch which reveals that workers with low pinch strength have more probability of CTS than that of the workers with high pinch strengths. ANOVA test with the help of SPSS software is use to analysis of sEMG signals of APB muscle in present study shows healthy worker have better sEMG single than that of non healthy workers which reveals that non healthy workers are more prone to CTS.

Genetic variability, heritability and genetic advance studies for physico-chemical characters of apricot germplasm under Ladakh region

On the basis of survey, a total of eighty three accessions were collected from apricot growing areas of Ladakh region scattered in three valleys, namely, Indus, Suru, Nubra and evaluated accordingly. The analysis of variance revealed significant differences in the accessions for all the quantitative and qualitative characters and indicated that noticeable variability is present in the apricot germplasm. All the 26 characters showed positive phenotypic variance (PV) as well as genotypic variance (GV). It was found that PV was higher than GV in all the characters under study except in five characters, viz., kernel cheek diameter, kernel weight, kernel volume, acidity and reducing sugars were PV and GV was found to be equal. It was also noticed that except three characters, i.e., pH of juice, acidity and reducing sugar, all the characters showed higher magnitude of phenotypic coefficient of variation (PCV) than genotypic coefficient of variance (GCV). The Maximum heritability was recorded in acidity (79.75) followed by kernel cheek diameter (99.40) with least heritability percentage was recorded in leaf petiole length (69.39). The trait kernel cheek diameter (89.601) showed highest genetic advance followed by pulp weight (71.00), fruit volume (67.32) and fruit weight (66.98) with a lowest of 2.93 for kernel volume, respectively.

Efficacy of biological, organic and inorganic substrates of nutrients on yield attributing characters, sensory evaluation and economics of strawberry cv. Chandler under Lucknow conditions

A field experiment was conducted for two years to study the performance of strawberry cv. Chandler as affected by the biological, organic and inorganic nutrient substrates under sub-tropical conditions. Integrated application of strawberry runners with bio-fertilizers, farmyard manure and NPK significantly influenced the yield and yield attributing characters, sensory attributes and benefit: cost ratio of strawberry grown under saline soils of sub-tropical conditions of Uttar Pradesh. Treatment T8 [Azotobacter (50%) + Azospirillum (50%) + NPK (50%)] was most effective for commercial cultivation with higher yield (287.0 g/plant), better fruit quality, overall acceptability by the consumers and remunerative (B:C, 4.78:1.00) to the farmers compared to control (141.57 g/plant).
