Adoption of Integrated Pest Management Practices in Paddy and Cotton: A Case Study in Haryana and Punjab

The study has examined the adoption of IPM practices on cotton in Punjab and on paddy in Haryana and has assessed the impact of key socio-economic and institutional factors on IPM adoption. The Poisson count regression models have been used to analyze technology adoption. The awareness generation about technology through formal crop-specific IPM training provided by the farmers’ field schools has been found extremely effective in wider adoption of IPM in the study areas. Hence, investment in IPM education through these programmes will have long-term beneficial impact. Regarding effectiveness of extension services, the study has not shown (frequency of meeting extension personnel) any statistically significant impact on IPM adoption rates. Mixed evidence has been observed about the relationship between farm-size and adoption of IPM practices. In the case of paddy, a negative relationship has been observed, while the cotton has shown a positive relationship. The study has concluded that a higher gross value of crops does not appear to have a positive impact on IPM technology adoption in cotton.Crop Production/Industries,

Some Experimental Studies on Heat Transfer Augmentation for Flow of Liquid Hrough Circular Tubes Using Twisted Angles and Tape

Heat exchangers have several industrial and engineering applications. The design procedure of heat exchangers is quite complicated, as it needs exact analysis of heat transfer rate and pressure drop estimations apart from issues such as long-term performance and the economic aspect of the equipment. Whenever inserts are used for the heat transfer enhancement, along with the increase in the heat transfer rate, the pressure drop also increases. This increase in pressure drop increases the pumping cost. Therefore any augmentation device should optimize between the benefits due to the increased heat transfer coefficient and the higher cost involved because of the increased frictional losses

First principles design of divacancy defected graphene nanoribbon based rectifying and negative differential resistance device

We have elaborately studied the electronic structure of 555-777 divacancy (DV) defected armchair edged graphene nanoribbon (AGNR) and transport properties of AGNR based two-terminal device constructed with one defected electrode and one N doped electrode, by using density functional theory and non-equilibrium Green's function based approach. The introduction of 555-777 DV defect into AGNRs, results in a shifting of the {\pi} and {\pi}* bands towards the higher energy value which indicates a shifting of the Fermi level towards the lower energy. Formation of a potential barrier, very similar to that of conventional p-n junction, has been observed across the junction of defected and N doped AGNR. The prominent asymmetric feature of the current in the positive and negative bias indicates the diode like property of the device with high rectifying efficiency within wide range of bias voltages. The device also shows robust negative differential resistance (NDR) with very high peak-to-valley ratio. The analysis of the shifting of the energy states of the electrodes and the modification of the transmission function with applied bias provides an insight into the nonlinearity and asymmetry observed in the I-V characteristics. Variation of the transport properties on the width of the ribbon has also been discussed.Comment: 28 Pages, 12 Figures and 1 tabl

Importance of Alginate Bioink for 3D Bioprinting in Tissue Engineering and Regenerative Medicine

Among many bioinks used for extrusion 3D bioprinting, the most commonly used bioink is the polysaccharide alginate because of its various cellular-friendly property like gelation. Erratic degradation and cell-binding motifs are not present in alginate which are the limitations of alginate bioinks, which can be improved by blending various low concentrations of natural or artificial polymers. Here in this chapter, we will discuss the various important properties of the alginate which make it as the bioink for almost all bioprinting scaffold designs as well as how improve the cellular properties like its cell-material interaction by blending it with other polymer solutions

Application of Artificial Intelligence in Modern Healthcare System

Artificial intelligence (AI) has the potential of detecting significant interactions in a dataset and also it is widely used in several clinical conditions to expect the results, treat, and diagnose. Artificial intelligence (AI) is being used or trialed for a variety of healthcare and research purposes, including detection of disease, management of chronic conditions, delivery of health services, and drug discovery. In this chapter, we will discuss the application of artificial intelligence (AI) in modern healthcare system and the challenges of this system in detail. Different types of artificial intelligence devices are described in this chapter with the help of working mechanism discussion. Alginate, a naturally available polymer found in the cell wall of the brown algae, is used in tissue engineering because of its biocompatibility, low cost, and easy gelation. It is composed of α-L-guluronic and β-D-manuronic acid. To improve the cell-material interaction and erratic degradation, alginate is blended with other polymers. Here, we discuss the relationship of artificial intelligence with alginate in tissue engineering fields

NOVEL DELIVERY APPROACHES OF CO-TRIMOXAZOLE FOR RECREATING ITS POTENTIAL USE-A REVIEW

Co-trimoxazole appropriates to category of broad-spectrum antimicrobial. They are active upon administration in vitro against an extensive collection of microorganisms. Their application in medical field has roughly spanned over decade now. There are numerous approaches that were progressed for improving their effectiveness towards their antimicrobial potency. However, routine use of this could accelerate the chance of bacterial resistance, and portrait it ineffective when required to treat infection. Consequently, newer investigations are necessary to keep the drug effective by minimise the development of resistance and maximise its safe use. Safe use is meant by safe delivery of drug in low dose, low frequency at the targeted molecule by effective ways. This can be achieved by using nanocarrier systems as they possess smart characteristics of effective drug delivery. These nanocarrier systems are including nanoparticle, liposomes, nanogels etc. Present review article deals with the historical perspectives with regards to co-trimoxazole, their mechanism of act/resistance and spectrum of activity in first section. In second portion different novel carriers, importance and application of nanogels, rational for co-trimoxazole nanogels are discussed. In conclusion, different literatures have proved the efficacy of nanogels in delivery of antimicrobial drug similar to co-trimoxazole. In the present time very less data is available for delivery of this drug with novel carriers. Therefore, this review aims to encourage researchers for creating some new findings in this perspective
