Abstract This study reports the microwave synthesis of Guar gum (GG) and Carboxymethyl cellulose (CMC) based hydrogel covalently crosslinked using epichlorohydrin (epi), aiming to remove hazardous dyes like Crystal Violet (CV) and Brilliant Green (BG). The optimized parameters were the reaction time (40 s), solvent (12 ml), pH (11), the ratio of reactants (GG: CMC, 1 : 2), and crosslinker concentration (0.8 ml) resulting in the highest percentage of swelling (4215 %). The synthesized hydrogel was characterized by different techniques like FTIR, TGA, FESEM/EDX, and XRD. The adsorption ability of the synthesized hydrogel was assessed for the removal of toxic dyes. Different kinetic and isotherm models were used to evaluate the type of adsorption that occurred on hydrogel materials. The CV and BG were both removed in 96.78 and 94.01 % of the adsorption process, respectively. The pseudo‐second‐order kinetic model is the best‐fitted model for the adsorption of dyes on the synthesized hydrogel. Adsorption was determined to be homogeneous and physical adsorption, and it was revealed through adsorption isotherm studies that the Langmuir model was the best‐fitted model. The adsorption process for both dyes is spontaneous, as further confirmed by the negative values of the change in Gibbs free energy from 298 to 318 K. The synthesized hydrogel material was discovered to be a promising adsorbent to remove these toxic dyes from wastewater and can be used as an eco‐friendly and sustainable material for wastewater remediation

Knowledge, Attitudes and Practices of the Farmers towards Antibiotic Usage in Layer Birds in Haryana, India: A Cross-sectional Survey

Journal of Scientific Research and Reports (2024)

Khushbu Khushbu Pallavi Moudgil Vijay J. Jadhav Deepak Soni Yogesh C. Bangar

The antibiotic usage practices of poultry farmers have drastically changed over decades in most of the developing countries like India. The present study carried out in 100 layer farms of Haryana, India from March, 2022 to November, 2022 to assess the knowledge, attitudes and practices of farmers towards antibiotic usage in layer birds using structured questionnaire. The findings suggested that 39 (39%) farmers had correct knowledge, 67 (67%) farmers had positive attitudes and 64 (64%) farmers followed good practices towards antibiotic usage in layer farms. The statistical analysis revealed farmers owning small size farms had 0.12 times lower odds (p<0.01, OR=0.12, 95% CI=0.03-0.55) of positive attitudes than farmers owning large size farms. Further, the farmers who used self-made feeds at their farms had 5.08 times lower odds (p<0.01, OR=5.08, 95% CI=1.49-17.25) of positive attitudes towards antibiotic usage as compared to commercial feed users. An interesting finding of the survey was that farmers who had education level up to 12th grade showed 5.65 times higher odds (p<0.01, OR=5.65, 95% CI=1.52-20.93) of having better knowledge of antibiotic usage than graduate farmers. A high proportion of farmers even used antibiotics without proper consultation with the veterinarian. Thus, the study suggests that farmers owning small sized farms and using self-made feed had positive attitude towards antibiotic usage. Additionally, farmers who had education up to 12th grade showed better knowledge of antibiotic usage. There is a significant gap between farmer's knowledge and attitudes. Lack of strict legislation, restrictions on antibiotic use and farmer's self-prescription of antibiotics to the flock are highly accountable for the increasing antibiotic resistance and production of residues contaminated eggs which is a major threat to public health globally.

Contact Area Design of Ohmic RF MEMS Switch for Enhanced Power Handling

Anuroop Deepak Bansal Khushbu Khushbu Prem Kumar Amit Kumar

RF MEMS switches are small in size, consume low power and have good RF response. However, the field deployment of RF MEMS switches is restricted due to limited power handling capability and reliability issues. In literature, power handling is improved through contact area either by adding hard materials or increasing the thickness. In the present paper, calculations for contact area versus stiction forces are performed and RF MEMS ohmic switch with optimal contact area is proposed and fabricated. The power handling of RF MEMS switch is increased by 55.86% without the addition of new material or processing steps. Insertion loss and return loss of the switch are also improved using corner compensation.

Determination of cyromazine and Melamine residues in poultry eggs

International Journal of Veterinary Sciences and Animal Husbandry (2023)

Deepak Soni Vijay J. Jadhav Pallavi Moudgil Khushbu Khushbu

Cyromazine (CYR) and Melamine residues (MEL) in 40 samples of eggs were detected from layer farms located in selected districts of Haryana (Ambala, Jind and Panipat) using. High Pressure Liquid Chromatography (HPLC-UV). The separation was achieved using C18 column using acetonitrile and acidified TFA as a mobile phase (0.05%) with a flow rate of 1 ml/minute with UV detection at wavelength 214 and 230 nm at column temperature of 28 °C. Out of these, CYR was detected in 03 samples above the LOD (5.3 μg/kg). MEL was not detected in any of the sample analyzed. Cyromazine in the eggs can appear if the layer is subjected to fed cyromazine contaminated feed deliberately.

Temperature dependent ferroelectric properties of Sm and Fe substituted BaTiO₃

Integrated ferroelectrics (2018)

Khushbu Khushbu Parveen Kumar

The material series with compositional formula Ba1-xSmxTi1-xFexO3 (x = 0.0025, 0.0075, 0.01) was chosen and investigated for temperature dependent ferroelectric properties. The samples in powder form were synthesized by solid state reaction method and compacted in the form of circular discs which were sintered at 1325 °C. The ferroelectric properties were investigated by recording the PE hysteresis loops of all the samples at different temperatures (at 50 Hz). Remanent polarization ‘Pr’ and Coercive field ‘Ec’ of all samples was noted from PE loops. These studies demonstrate the potential for use in applications at elevated temperatures such as in non-volatile ferroelectric memory applications.

Journal of Pharmacognosy and Phytochemistry (2018)

Manisha Kumari Rolaniya Mahendra Bairwa Khushbu Khushbu S. Sarvanan

An investigation entitled, â€œEffect of plant growth regulators on rooting of hardwood of grape (Vitis vinifera) cv. Thompson seedlessâ€ was carried out with 3 regulators (IAA with 100, 300, 500 ppm concentration, IBA with 1000, 2000 and 3000 ppm concentration and GA3 with 50, 100, 150 ppm concentration) and control treatment. The observations from 10 randomly selected plants from each replication were recorded for quantitative traits viz. First emergence of node, Average number of leaves per cutting, Average number of buds per cutting, Dry weight of shoots, First emergence of root, Average number of roots per cutting, Average root formation zone, Average length of longest root, Average thickness of thickest roots, Dry weight of roots, Fresh weight of roots and Survival percentage of cutting. The results showed that most of the shoot and root characters of cuttings were significantly influenced by the different treatments of growth regulator as compared to control. Results showed that the treatment GA3 150ppm (T9) had taken least number of days (9 days) for emergence of first node and IBA-2000 (T4) had taken minimum number of days for emergence of first node and vice versa for the first emergence of the node. After 90 days after planting, maximum number of leaves (21.6), Average number of buds per cutting (9.93), Average number of roots per cutting (30.54), Average root formation zone (29.74cm), Average length of longest root (28.24 cm) and Average thickness of thickest roots (1.78 mm) were observed in the treatment which was treated with IBA @ 2000ppm followed by 3000ppm IBA. The least values were noted with control. The combination with 2000 ppm IBA was found best for maximum rooting, growth and success of grapes cuttings followed by combination of 3000 ppm IBA under this study.

NUTRACEUTICAL ASPECTS OF AZOLLA: A LOW-COST ORGANICINPUT FOR LIVESTOCK

International Journal of Biological Innovations (2022)

Khushbu Khushbu Rachna Gulati Sushma Sushma

Livestock has a significant role in the world economy. Livestock is the major source of livelihood for about 20.5 million people in India and livestock resources contribute 4.11% of the country's GDP and 25.6% of total agriculture GDP. On the other hand, there is a huge gap between demand and supply of feed and fodder in India, which can be reduced by exploring natural feed resources as supplements. To complete the shortage of feed and optimum production of livestock, it is significant to explore some non-conventional nutritive feed resources. The aquatic fern, Azolla has been identified as one of the most efficient substitutes for livestock as it can be easily digested due to its low lignin with high protein content having especially essential amino acid lysine. Its unique nutrient aspects make it an ideal feed for livestock, poultry, goat, fish, and pigs. Nutraceutical aspects of Azolla bio-feed technology will be taken up in a big way by the dairy farmers, especially, by those who experience land scarce conditions for fodder production.
