A Thorough Insight to Techniques for Performance Evaluation in Biological Sensors

The biological sensor has played a significant and contributory role in the area of medical science and healthcare industry. Owing to critical healthcare usage, it is essential that such type of sensors should be highly robust, sustainable under the adverse condition and highly fault tolerant against any forms of possible system failure in future. A massive amount of research work has been done in the area of the sensor network. However, works done in biological sensors are quite less in number. Hence, this manuscript highlights all the significant research work towards the line of discussion for evaluating the effective in the techniques for performance evaluation of biological sensor. The study finally explores the problems and discusses it under research gap. Finally, the manuscript gives highlights of the future direction of the work to solve the research gap explored from the proposed review of the existing system

Enzymes of Ammonia Assimilation in Fungi: An Overview

Nitrogen is a major element found in many of the simple compounds and nearly all of the complex macromolecules of living cells. Nitrogen can be obtained either from organic source or inorganic source but ultimately it is converted into ammonia and glutamate. Ammonia is the preferred   source of nitrogen. The assimilation of ammonia into glutamate and glutamine plays a central role in the nitrogen metabolism of all organisms. Glutamate dehydrogenase (GDH), Glutamate synthase (GOGAT), and glutamine synthetase (GS) are the key enzymes involved in ammonia assimilation. The specific steps in these pathways vary with the organism, but in virtually all cells glutamate (85%) and glutamine (15%) serve as the nitrogen donors for biosynthetic reactions. In fungi lot of work has been carried out on these enzymes from lower fungi to the higher ones and there are differences in the role played by theses enzymes. Thus knowledge of the formation of glutamate and glutamine from various nitrogen sources is crucial to our understanding of cell growth.  In this review an overall view of the elements present in ammonia assimilation especially in fungi will be carried out along with recent developments and concepts

Structural, DC Conductivity and Electric Modulus Studies of Polypyrrole Praseodymium Manganite Nanocomposites

Praseodymium Calcium Manganite (PCM) nanoparticles were synthesized by sol-gel method. Polypyrrole (PPy) and polypyrrole–praseodymium manganite nanocomposites (PPy/PCM) were synthesized by in-situ chemical polymerization method. Transmission electron microscope (TEM) confirmed good crystallinity with 42-63 nm average particle size. Scanning electron microscope (SEM) exhibited well-defined core structure of PPy and the PPy/PCM nanocomposites. X-ray diffraction (XRD) patterns of PPy showed amorphous nature and those of composites showed semicrystalline nature. UV-Vis spectroscopy was used to study the energy band gap for all the nanocomposites and hence they may find a place in wide band gap applications. The UV (231nm) and visible (363 nm and 377 nm) emissions were observed from the spectrum. DC conductivity was studied from 473 to 303 K for all the nanocomposites and found that conduction is of semiconductor type. Analysis of electric modulus confirmed the contribution from grain and grain boundary, non-Debye type relaxation and dc conductivity obeyed Correlated Barrier Hopping (CBH) model

Robotics and automation in the city: a research agenda

Globally cities are becoming experimental sites for new forms of robotic and automation technologies applied across a wide variety of sectors in multiple areas of economic and social life. As these innovations leave the laboratory and factory, this paper analyses how robotics and automation systems are being layered upon existing urban digital networks, extending the capabilities and capacities of human agency and infrastructure networks, and reshaping the city and citizen’s everyday experiences. To date, most work in this field has been speculative and isolated in nature. We set out a research agenda that goes beyond analysis of discrete applications and effects, to investigate how robotics and automation connect across urban domains and the implications for: differential urban geographies, the selective enhancement of individuals and collective management of infrastructures, the socio-spatial sorting of cities and the potential for responsible urban innovation

Feasibility of Drain Discharge Under 50 M Lateral Spacing Controlled Subsurface Drainage in Saline Vertisols of TBP Command Area

Surface and subsurface drainage discharge water from irrigated agriculture field is normally varies compared with the quality of the canal water supply as the drain discharge water from different locations or facilities will varied in their quality characteristics. Hence, quality assessment or feasibility studies of drain discharge both in short and long term adoption of both conventional and controlled SSD under different drain spacing is prerequisite for its reuse in crop production and efforts are being made elsewhere for reuse of drainage discharge in crop production. Such, feasibility studies on characterization of drain discharge from different subsurface drainage systems are lacking in TBP command area.  Hence, it is proposed to conduct this experiment. A plot experiment was conducted during rabi -2021 at Agricultural Research Station, Gangavati (Karnataka) to study the the characterization of drain discharge water for its reuse as an irrigation water. The experiment was laid out as a conventional and controlled subsurface drainage system (SSD). Among the treatments, the collected water samples from six different sampling stations revealed that, drain discharge under conventional subsurface drainage system (SSD) varied from 3.66 to 0.63 compared to 1.38 to 0.42 mm/day under controlled subsurface drainage system. Electrical conductivity of drain discharge water under conventional SSD varied from 3.89 to 1.24 ds/m as against 1.01 to 0.81 ds/m under controlled SSD respectively. While, salt output was varied from 29.0 to 11.0 under conventional compared to 16.5 to 2.5 kg/ha under controlled SSD system. Finally, the subsurface drainage system drain water samples were not suitable for reuse as irrigation water to paddy in the R/S season as per the classification of irrigation water quality particularly for poorly drained black soils in the TBP command area
