Design, Development and Performance Evaluation of Eddy Current Displacement Sensor Based Pressure Sensor with Target Temperature Compensation

In Aerospace applications, pressure measurement plays a vital role as it serves as one of the input to onboard controller to aid decision- making on initiating or terminating some of the critical events. In this paper, the design aspects of pressure sensor using linear eddy current displacement sensor (ECDS) are presented along with its performance evaluation. The static calibration is carried out to select the best position of ECDS in the proposed pressure sensor. The effect of target temperature on sensor output is presented with test results to aid compensation. A compensation algorithm is developed to minimise the error due to target temperature. The developed compensation algorithm is validated using thermal calibration. The designed pressure sensor is calibrated using Arson dynamic pressure calibrator to evaluate its bandwidth. The calibration results are analysed to aid future sensor design towards improvement of accuracy, bandwidth and miniaturisation

Some observations on the possibilities of culture of the Indian sand whiting Sillago sihama (Forskal) in brackish waters

Indian sand whiting, Sillago sihama (Forskal) forms a dominant species in the estuarine fish catches during the south-west monsoon when they are in great demand and fetch a high price as sea fishing remains suspended due to rough weather conditions. The paper deals with preliminary observations on certain aspects of the biology of the fish related to its culture. The ability of the species to withstand very wide raoges of salinity makes it suitable for culture io both brackish and fresh waters

Early neonatal outcome in late preterms compared with term neonates

Introduction: Neonates born between 34 weeks and 36 weeks 6 days of gestational age (GA) are known as late preterm neonates. These late preterm neonates are the largest subgroup of preterm neonates. There have been few studies regarding the early morbidity in this cohort of neonates when compared to neonates born at term. Objectives: The objectives of the study were to study the incidence and various causes of early morbidities and mortality in late preterm neonates and to compare with term neonates. Materials and Methods: This prospective cohort study was conducted at a tertiary care teaching institution of Bengaluru. All late preterm and term neonates born between December 2016 and July 2018 were enrolled in the study. Data regarding parity, mode of delivery, sex, GA, birth weight, predefined neonatal morbidities, and maternal risk factors were all entered in the pre-designed pro forma. The morbidities and mortality of these late preterm neonates were compared with the term neonates. Results: A total of 408 late preterms and 1660 term neonates were enrolled in this study. These late preterm neonates were at significantly higher risk of overall morbidity due to any cause (85.3%, p<0.001, adjusted odds ratio [OR]: 1.4, 95% confident interval [CI]=0.8–2.4). They were also at higher risk of developing respiratory distress (23.5%, p<0.001, adjusted OR: 1.5, 95% CI: 1.1–2.2), need for ventilation ([Nasal continuous positive airway pressure – 8.6%] [synchronized intermittent mandatory ventilation [SIMV] – 3.7%], p<0.001), and neonatal sepsis (9.1%, p=0.003, adjusted OR: 1.3, 95% CI=0.3–3.3) when compared with term neonates. Conclusion: Gestational maturity is the most important determinant of the outcome in newborns. Late preterm neonates are not the same as term neonates as evidenced by the high incidence of complications in late preterm compared to term infants

Genome wide analysis of NAC transcription factors and their expression pattern during high temperature and drought stress in groundnut

NAC (NAM, ATAF1/2 and CUC2) is a prime plant specific transcription factor, which plays a pivotal role in stress signaling. Excavating a relatively large number of NAC TFs under complex environmental cues and understanding their molecular basis,\ua0remains a challenge. The objective of this study was to analyse a total of 76 NAC transcription factors of which 38 were from Arachis duranensis (AdNAC) and Arachis ipaensis (AiNAC) for phylogeny, chromosomal location, conserved motif identification including membrane bound NTLs (NAC trans-membrane like), promoter analysis and expression profiles under high temperature and drought stress.\ua0The study led to the identification of eight membrane bound NTLs, such as AdNAC26, AdNAC36, AiNAC16, AiNAC17, AiNAC37, AdNAC14, AiNAC12, and AiNAC29, and revealed that majority of NAC proteins had four NAC domain- containing conserved motifs and were localised at the nucleus. The study also reveals AdNAC21 and AiNAC3 as positive regulators under both stress conditions. Our results provide a basis for selection of promising stress- responsive NAC candidates for further functional analysis, leading to development of transgenics with improved productivity of groundnut varieties under drought and high temperature.NAC (NAM, ATAF1/2 et CUC2) est un facteur sp\ue9cifique primordial dans la transcription chez la plante, qui joue un r\uf4le principal dans la signalisation des stresses. Fouiller un nombre relativement important de NAC TFs sous le complexe des signaux environnementaux et comprendre leur base mol\ue9culaire, demeurent un d\ue9fi. L\u2019objectif de cette \ue9tude \ue9tait d\u2019analyser un total de 76 facteurs de transcription desquels 38 sont de Arachis duranensis (AdNAC) et Arachis ipaensis (AiNAC) pour la phylog\ue9nie, la localisation chromosomique, l\u2019identification du motif conserv\ue9 y comprises la membrane li\ue9e NTLs (semblable \ue0 NAC transe-membrane), analyse du promoteur et les profils d\u2019expression sous le stress de haute temp\ue9rature et de s\ue9cheresse. L\u2019\ue9tude a conduit \ue0 l\u2019identification de huit membranes NTLs li\ue9es, telles que AdNAC26, AdNAC36, AiNAC16, AiNAC17, AiNAC37, AdNAC14, AiNAC12, et AiNAC29, et a r\ue9v\ue9l\ue9 que la majorit\ue9 des prot\ue9ines NAC ont quatre domaines NAC- contenant des motifs conserv\ue9s et sont localis\ue9s dans le noyau. L\u2019\ue9tude a aussi r\ue9v\ue9l\ue9 AdNAC21 et AiNAC3 comme r\ue9gulateurs positifs sous les deux conditions \ue0 la fois. Nos r\ue9sultats ont fourni une base pour la s\ue9lection des NAC candidats donnant de r\ue9ponses satisfaisantes aux stresses pour une analyse fonctionnelle avanc\ue9e, conduisant au d\ue9veloppement des transg\ue9niques avec des vari\ue9t\ue9s d\u2019arachide \ue0 rendement am\ue9lior\ue9 sous la s\ue9cheresse et une haute temp\ue9rature

Production pattern in the marine fisheries of Kerala

Fisheries play a crucial role in the Kerala economy. Although the coastline is only about one tenth of the coastline of India, landings in Kerala constitute more than 30 pet of the country's total marine fish production. This sector provides the main source of income for about 147900 active fishermen and for almost an equal number engaged in the activities of processing and marketing. Earnings from export of marine production from Kerala have during the past two decades increased considerably. The marine fisheries sector is therefore one of the major concerns of the economic planners in the state of Kerala and the object of A various development programmes
