    Abstract The current study includes the assessment of physico-chemical characteristics along with the microbial diversity of hot water samples collected from three important sacred hot water springs of the Uttarakhand Himalaya close to the world-famous Hindu shrine Yamunotri temple. Hot water samples were collected for two consecutive years 2015-2016 in two sampling operations each year. A total of fifteen physico-chemical attributes of hot water were recorded. Microbes of hot water ponds were characterized by morphological, biochemical, MALDI-TOF MS, and molecular approaches. A total of twenty-two microbial strains were identified from the Surya Kund with water temperature ranging between 86 °C and 89 °C; twenty-two microbial strains were identified from the Draupadi Kund with water temperature ranging between 65 °C and 69 °C and twenty-one microbial strains were identified from the Yamunotri Tapt Kund with water temperature ranging between 45 °C and 48 °C during the study period. The present study on the assessment of physico-chemical characteristics and thermophilic microbial diversity of all the three hot water springs can be a useful reference for further studies on similar aspects in other parts of the Himalaya. The available data will also help to understand the reasons behind the curative properties of these hot water springs. This baseline information will also be instrumental for the conservation and management of these hot water springs.

  3. Article ; Online: Seasonal Variability in Transcript Expression of Type I and Type II Keratins in Wool Follicles of Lustrous Fleece-Producing Magra Sheep

    Abstract Magra sheep reared around the Bikaner area of Rajasthan, India is famous for producing lustrous fleece as compared to other wool-producing native sheep breeds. Three clips of Magra wool, namely, February, July, and October months of the year are showing variations in luster and gross appearance. Present work has been conducted to unravel seasonal variations, in transcript expression patterns in major type I and type II keratin genes, that occur in wool follicles of lustrous wool-producing Magra sheep. Wool samples randomly collected were graded in high and low luster by Gloss 60° values. Wool follicles of the sheep with low (gloss 60° values; < 2.5) and high (gloss 60° values; > 2.5) luster were used for the analysis of type I and type II keratin transcripts. The results of Quantitative PCR had shown up-regulated expression of keratin genes in high-lustrous sheep as compared to low-lustrous sheep. K32, K40, and K82 transcript expression differed significantly (P ≤ .05) between high- and low-lustrous sheep. Nucleotide sequence analysis of the K40 and K82 genes revealed five and four non-synonymous mutations, respectively. From the present study, it can be speculated that the higher amount of keratin protein may play a crucial role in determining the luster property of the wool.

    Abstract The management of natural surface water resources needs the understanding of water quality. The present study on the physico-chemical parameters of water quality of sacred lake Nachiketa Tal of Garhwal Himalaya was undertaken. During the period from May 2015 to April 2016 at four sampling stations, seasonal variations in air temperature, water temperature, electrical conductivity, turbidity, salinity, TDS, dissolved oxygen, free CO2, hardness, alkalinity, nitrates, phosphates, chlorides, calcium and magnesium were recorded. The statistical correlation and cluster analysis between the various physico-chemical parameters of Nachiketa Tal were computed. The results of this study revealed that the concentration of the nutrients, turbidity, electrical conductivity, TDS increased with a decreasing trend of dissolved oxygen in all the sampling stations during the monsoon season. Thus, degradation in the water quality of the lake was resulted in the monsoon season.

    Abstract Satopanth Lake is a glacial lake, located at an altitude of 4600 m above sea level in Garhwal Himalaya of Uttarakhand state in India where an attempt was made to assess the water quality. A total of sixteen physico-chemical parameters including temperature, hardness, alkalinity, dissolved oxygen, conductivity, pH, calcium, magnesium, chlorides, nitrates, sulphates and phosphates were recorded during 2014 and 2015 between June and August in ice-free period. The mean values of pH ranged from 6.85 to 7.10; water temperature fluctuated from 0.1 to 0.3 °C; dissolved oxygen varied from 5.90 to 6.0 mg.L⁻¹; free CO₂ varied from 8.40 to 8.60 mg.L⁻¹; total dissolved solids varied from 88.0 to 89.5 mg.L⁻¹; calcium from 7.88 to 7.95 mg.L⁻¹; magnesium from 0.53 to 0.66 mg.L⁻¹. All the physico-chemical values were within the prescribed WHO/BIS limit for drinking water. Water Quality Index (WQI) calculated based on these parameters also revealed the excellent quality of lake water.

    Abstract A novel pump-probe Photothermal methodology using Quartz Tuning Fork (QTF) detector has been demonstrated for the first time. A tunable mid-IR Quantum Cascade Laser (QCL) and a CW fixed wavelength visible laser have been used as the pump and probe beam respectively. The developed Photothermal (PT) technique is based on Quartz Tuning Fork (QTF) detector for the detection of hazardous/explosive molecules adsorbed on plastic surface and also in aerosols form. PT spectra of various trace molecules in the fingerprinting mid- infrared spectral band 7-9 µm from distance of 25 m have been recorded. The PT spectra of explosives RDX, TNT and Acetone have been recorded at very low quantities. Acetone is the precursor of explosive Tri-Acetone Tri-Phosphate (TATP). The experimentations using pump and probe lasers, exhibit detection sensitivity of less than 5 μg/cm

    Abstract Technostress is defined as any unhealthy condition caused by dealing with modern technology in various harmful ways; examples of technostress include addiction and stress. Even though technostress has been extensively studied in the literature, little attention has been paid to investigating technostress among academics who work in exceptional circumstances, such as crises, and who might be experiencing different psychological states due to those circumstances. To fill the gap, this study aims to explore the factors influencing technostress among school teachers. The study examined technostress's level and factor graphics structure among 692 academics from different Arab countries during COVID-19. The technostress factors and their stories were explored and measured using sequential mixed methods and confirmatory and exploratory factor analysis. The study discusses various factors' direct and indirect effects on mobile technology integration in education and the theoretical and practical implications of managing technostress in online classes. A model of techno-stressors among Arab academics was found to include: schedule overload, complexity, uncertainty, uselessness, invasion, and compulsion. The direct effect of various factors on mobile technology integration in education is mainly positive, while indirect effects are more varied. The theoretical and practical implications of managing technostress in online classes include: considering the psychological and physiological impact of technostress on students' learning performance, decreasing overall satisfaction with the learning experience, and improving the overall quality of online courses. As a result of this study's findings, a new perspective is provided on how academics in particular circumstances (in this study, the occupation of Palestine) may behave and feel toward technology in teaching.

    Abstract Laser induced moving dynamics grating has been studied in fluorescein doped boric acid glass films in the limit of a weak probe and a relatively strong pump. The results have been interpreted in terms of the four-level description of a saturable absorber. Good agreement has been obtained in the experimental and the fitted results. Estimated values of the non-linear parameters such as the saturation intensity, refractive index, and also the response time of the optical non-linearity have been obtained at different strong pump beam intensity.
