Abstract:

Abstract The article deals with the construction of a single-channel light rangefinder. At the same time, one of the main difficulties is the presence of depolarization of light, which forms residual light at the output of the analyzer, which greatly affects the measurement accuracy. It is shown that in order to exclude residual light by compensating for depolarization, a KDP crystal plate with the possibility of rotation in a plane parallel to the optical axis is installed at the input of the demodulator. The possibility of using an optical delay line on a single mirror with the possibility o

Abstract:

AbstractImpedance spectroscopy represents a basic operating principle for biomedical sensors, bioimpedance spectroscopy, electrochemical analyses and for characterization of functional biomaterials. For automated long-term investigations, an impedance analyzer for multi-channel testing of up to eight passive two-pole networks is presented in this paper. Its operating system is application-specific adapted to the required test functionalities and measuring ranges. Measurements are based on a commercially available integrated impedance converter circuit. Our current analyzer setup is capable of

Abstract:

A position-sensitive proportional counter (PSPC) for a wavelength-dispersive crystal spectrometer system has been constructed for high-resolution PIKE experiments in atmospheric air. This PSPC has seven resistive wire anodes. Each anode operates as one PSPC. Pulses from the anodes are converted into digital signals with a 512 × 7 channel charge-division analyzer. We can simultaneously obtain seven spectra. A computer software converts this 2D data set into one spectrum after adjusting the offset channels and conversion factors.

Abstract:

A vector network analyzer (VNA) is an expensive and essential device for measuring the scattering coefficients of RF devices in the research and development of microwave systems. However, these VNAs are limited in that they can be only used by one user. To address this limitation, this paper presents a switching system that allows multiple users to measure each device under test using a single VNA at the same time. In particular, a four-user switching system is developed in this study. It is important to calibrate the differences between each channel that inevitably arise during implementation

The energy dependence on channel number was established, ensuring accurate energy characterization of the measured spectra. The effect of air pressure on α-particle spectra was analyzed by varying the pressure from vacuum to 500 hPa and 1000 hPa.

The method has been employed for the analysis of pyrolusites and results were found in good agreement with those from conventional chemical methods.

Binding of a protein at a ligand-modified ion channel can lead to closure or distortion of the channel, resulting in a digital on/off response of the ion flux. This principle could be applied as a strategy for sensor design using artificial membrane ligands or receptors. Important details of modeling and a technique of realization of the new molecular electronic sensor device are presented. The response of the sensor induced by analyte binding depends on the analyte's size and ability to close or distort the ion channel.

Introduction. The aim of the study was to evaluate the diagnostic capabilities of various modifications of portable analyzers LAZMA-PF when studying the state of microcirculation depending on the tasks set.Materials and methods. Synchronous assessment of lower extremity microcirculation using a distributed system of single-channel analyzers LAZMA-PF, was performed in patients with unilateral coxarthrosis (n=37) in the initial state and after hip joint replacement. In patients with colorectal cancer (n=27) and in the healthy control group (n=30), a comparative assessment of microcirculation and

Abstract:

The activated clotting time (ACT) is a standard method of heparin monitoring during cardiac angioplasty and cardiac surgery. A modified ACT (ACT+) which employs a microsample blood volume (0.05 ml) and yields faster clotting time results than a conventional Hemochron ACT was evaluated and compared to the standard ACT. The ACT+, determined using a single channel general purpose analyzer (Hemochron Jr.), employs a plastic cuvette containing dried ACT reagents (kaolin-silica-phospholipid). In vitro evaluation of heparinized normal donor blood demonstrated the test insensitivity to aprotinin. Usin

Abstract:

In mountainous areas, a river can widen from a single channel to a compound channel under the influence of geological conditions or human impacts, bringing about challenges in terms of flood control and channel regulation. This paper reports the results of tests conducted in a 26 m long flume with a uniform sediment bed (grain size = 0.5 mm), investigating the flow characteristics and bed morphology in a compound channel between two single channels. The stage‒discharge relationship in the compound channel and the longitudinal and cross-sectional bed profile in the compound channel between two

Abstract:

The main aim of this work is to analyse the significance of cutting parameters on surface roughness and spindle vibrations while machining the AA6063 alloy. The turning experiments were carried out on a CNC lathe with a constant spindle speed of 1000rpm using carbide tool inserts coated with Tic. The cutting speed, feed rate and depth of cut are chosen as process parameters whose values are varied in between 73.51m/min to 94.24m/min, 0.02 to 0.04 mm/rev and 0.25 to 0.45 mm respectively. For each experiment, the surface roughness parameters and the amplitude plots have been noted for analysis.

Persistent high serum triglyceride (TG) and free fatty acid (FFA) levels, which are common in metabolic syndrome and type 2 diabetes, are risk factors for cardiovascular events because of exacerbated hemorheology.

Abstract:

As greenhouse gas emissions from dairy farms are on the rise, effective monitoring of these emissions has emerged as a crucial tool for assessing their environmental impacts and promoting sustainable development. Most of the existing studies on GHGs from dairy farms involve stationary detections with long response times and high costs. In this study, a greenhouse gas detection system was constructed based on NDIR technology using a single broadband light source and a four-channel thermopile detector for the detection of CH4, N2O, and CO2; the detection range of CH4 was 0~100 ppm; that of N2O w

Abstract:

Multichannel communication has great potential in environments with unknown interference patterns. However, existing link quality metrics and models are generally established and verified under a single-channel scenario, which does not consider the impacts of radio interference and channel change. Therefore, it is hard to directly judge whether these metrics and models are still valid under a multichannel scenario. This paper empirically analyzes the applicability of popular link quality metrics and models in multiple channels with different interference levels. Results show that the link qual

Spontaneous miniature outward currents (SMOCs) in parasympathetic neurons from mudpuppy cardiac ganglia are caused by activation of TEA- and iberiotoxin-sensitive, Ca2+-dependent K+(BK) channels. Previously we reported that SMOCs are activated by Ca2+-induced Ca2+ release (CICR) from caffeine- and ryanodine-sensitive intracellular Ca2+ stores. In the present study, we analyzed the single channel currents that contribute to SMOC generation in mudpuppy cardiac neurons.

Abstract A lot of advancement in the field of semiconductors has made it possible to design a solid state neutron detector. They are small in size and compact, have economical bulk fabrications, require low power for their operation. Hence it can act as a plausible alternative to traditional neutron detector such as gas filled and scintillation detectors. It has been observed that many factors like the choice of converter material, LLD settings and geometrical configurations have an impact on the thermal neutron detection efficiency of solid state neutron detector design.
