This research focused on the thermal comfort behaviour of polyester with respect to the type of yarn (spun, micro denier, continuous filament and hollow), linear density of the yarn (111 and 166 dtex), and the loop length of knitted fabric (0.25, 0.27 and 0.29 cm).The air permeability of continuous filament yarn fabric and micro denier yarn knitted fabrics was noted to be higher than that of spun yarn knitted fabrics. 111 dtex micro denier yarn fabric has the highest air permeability and 111 dtex spun yarn fabric the lowest air permeability value among all the other fabric samples. Comparatively, coarser spun yarn fabric has lower air permeability characteristics than finer microdenier fabric.The water permeability of the fabric shows a significant difference between the spun yarn, continuous filament yarn and Micro denier yarn knitted fabrics and between the linear density of the yarn. The water vapour permeability of spun yarn of 166 dtex single jersey fabric is higher, while the water vapour permeability of continuous filament yarn fabric of 166 dtex is lower. The thermal conductivity value is high for continuous filament polyester fabric of 100 D and low for microdenier polyester fabric of 166 dtex. Based on the statistical analysis, it is clearly shown that there are significant differences between the three different polyester yarn fabrics of two different denier of the same fabric. Furthermore, the count and different polyester yarn affect the comfort properties of single jersey fabrics.

Background: Veterinarians in field conditions access different sources for gathering information on dairy husbandry activities. The information source used most frequently must be given due importance by the researchers and scientists to provide quality information. Methods: The present study was conducted among 120 field veterinarians of coastal Odisha. The sources used by the respondent veterinarians were identified and analysed for the extent of usage of the sources. The mean was calculated for frequency of accessing different sources for information on dairy husbandry activities as per the data collected in a 3-point continuum scale namely Always (2), Sometimes (1) and Never (0) and ranks were assigned accordingly. The effect of different independent variables on different information sources was analysed using one way ANOVA. Result: It was reported that usage of internet by the respondents was ranked 1st followed by WhatsApp 2nd, Personal contact 3rd, Phone calls 4th, Technical literatures 5th, books 6th, journals 7th, TV 8th, Apps 9th, SMS 10th and email 11th respectively. It was observed that the female respondent veterinarians were using books and journals significantly more than their male counterparts. Significant difference was observed in usage of books for acquiring information between the respondent veterinarians of young age group (up to 35 years) and old age group ( greater than 50 years). Significant differences were observed between the respondent veterinarians with less than 10 years of job experience and greater than 20 years of experience for using personal contact method with the lower estimates for the higher experienced group.
