A New Scheme for Determination of Respiration Rate in Human Being using MEMS Based Capacitive Pressure Sensor: Simulation Study

In this paper, a MEMS based capacitive nasal sensor system for measuring Respiration Rate (RR) of human being is developed. At first two identical diaphragm based MEMS capacitive nasal sensors are designed and virtually fabricated. A proposed schematic of the system consists of signal conditioning circuitry alongwith the sensors is described here. In order to measure the respiration rate the sensors are mounted below Right Nostril (RN) and Left Nostril (LN), in such a way that the nasal airflow

Effectors of large-conductance calcium-activated potassium channel modulate glutamate excitotoxicity
in organotypic hippocampal slice cultures

neuroprotective effects of BKCa channel modulators. Using organotypic hippocampal slice cultures exposed to glutamate, we demonstrated that preincubation of the slices with the BKCa channel opener NS1619 resulted in decreased neuronal cell death measured as reduced uptake of propidium iodide. This neuroprotective effect was reversed by preincubation with the BKCa channel inhibitors paxilline and Iberiotoxin (IbTx). Moreover, mitochondrial respiration measurements revealed that NS1619 induced an

Polymer Optical Fibre Sensor for Measuring Breathing Rate of Lying Person

. Signals from respiration as well as postural movements of a person lying on the POF sensor allow measurements to be taken in an unobtrusive manner. Bending losses attenuating light transmission through the fibre were related to displacement of POF during respiration (expansion and contraction of the chest cavity displace the surface in contact with the upper torso – in this case the meandering arrangement of the fibre sensor located on a TREDAIRE substrate). Bending losses were converted to

Nematode Fauna of Tropical Rainforest in Brazil: A Descriptive and Seasonal Approach

Studies of nematode assemblages in natural ecosystems can contribute to better understanding of the occurrence, relevance, and ecology of plant-parasitic and other soil nematodes. Nematode assemblages and environmental parameters (organic matter, water content (WC), bulk density (BD), total porosity (Po), soil respiration, and soil texture) were investigated in two seasons (rainy and dry) in two forest areas of the Zona da Mata, Pernambuco State. The aim of our research was to

A case study of soil food web components affected by Fallopia japonica (Polygonaceae) in three natural habitats in Central Europe

on the soil microbial and nematode community structure. Our objectives were to (i) determine the impact of F. japonica on soil pH and moisture, soil microbial respiration, soil microbial biomass carbon content, enzymatic activities and (ii) compare the abundance, diversity, trophic structure of nematode communities and selected ecological indices in three different habitats in F. japonica, the invaded and the uninvaded plots. The hypothesis tested was that soil physical properties, microbial, and

Correlation between portal vein diameter and craniocaudal length of the spleen

vein diameter was measured in quiet respiration at porta hepatis (near Porta hepatis). The diameter was measured by putting the two cursors in the lumen of the portal vein; the walls of the portal vein were excluded from the measurement. Statistical Package for the Social Sciences (SPSS) version 24 (SPSS 24, IBM, Armonk, Ny, United States of America) software was used for the evaluation of data and formation of graphs. The results were summarized in the form of graphs, tables, and charts

Effects of integrated application of plant-based compost and urea on soil food web, soil properties, and yield and quality of a processing carrot cultivar

micronutrients, percent of soil moisture content, and bulk density, and soil respiration were measured before planting and at harvest in 2012 and 2013 growing seasons. Soil moisture content level in each sample was determined by weight loss after oven dry at 104°C for 24 hr. Bulk density measurements were done drying cores of soil at 104°C for 24 h (Blake and Hartge, 1986). Soil pH, phosphorus, potassium, calcium, magnesium, soil organic matter, nitrate-nitrogen, ammonium-nitrogen, and cation exchange
