Abstract:

This paper discusses the comparative results of surface and satellite measurements made during the Phase1 (25 March to 14 April), Phase2 (15 April to 3 May) and Phase3 (3 May to 17May) of Covid-19 imposed lockdown periods of 2020 and those of the same locations and periods during 2019 over India. These comparative analyses are performed for Indian states and Tier 1 megacities where economic activities have been severely affected with the nationwide lockdown. The focus is on changes in the surface concentration of sulfur dioxide (SO2), carbon monoxide (CO), PM2.5 and PM10, Ozone (O3), Nitrogen dioxide (NO2) and retrieved columnar NO2 from TROPOMI and Aerosol Optical Depth (AOD) from MODIS satellite. Surface concentrations of PM2.5 were reduced by 30.59%, 31.64% and 37.06%, PM10 by 40.64%, 44.95% and 46.58%, SO2 by 16.73%, 12.13% and 6.71%, columnar NO2 by 46.34%, 45.82% and 39.58% and CO by 45.08%, 41.51% and 60.45% during lockdown periods of Phase1, Phase2 and Phase3 respectively as compared to those of 2019 periods over India. During 1st phase of lockdown, model simulated PM2.5 shows overestimations to those of observed PM2.5 mass concentrations. The model underestimates the PM2.5 to those of without reduction before lockdown and 1st phase of lockdown periods. The reduction in emissions of PM2.5, PM10, CO and columnar NO2 are discussed with the surface transportation mobility maps during the study periods. Reduction in the emissions based on the observed reduction in the surface mobility data, the model showed excellent skills in capturing the observed PM2.5 concentrations. Nevertheless, during the 1st & 3rd phases of lockdown periods AOD reduced by 5 to 40%. Surface O3 was increased by 1.52% and 5.91% during 1st and 3rd Phases of lockdown periods respectively, while decreased by -8.29% during 2nd Phase of lockdown period.

Abstract:

Valsalva maneuver (VM) is one of the most important tests used to investigate the integrity of the autonomic nervous system (ANS), it can be used to assess the baroreflex activity since the baroreceptors innervated by both sympathetic and parasympathetic nervous systems.Therefore (VM) used to investigate the changes in the hemodynamic variables in order to assess the integrity of cardiovascular system. The procedure of (VM) involves four phases through these phases the following measurements take place:1.Measurement of stroke volume (SV) which is the volume of bloodpumped from the heart by each beat using echocardiographic technique.2.Heart rate (HR) is recorded by ECG in order to count the number of heart beats per each minutes.3.Cardiac output (CO) which is the volume of blood pumped from the heart per each minute can be calculated by the equation CO = HR Ã— SV from the above points (1,2).4.Blood pressure measurement during (VM) by using mercury sphygmomanometer by which measurement of SBP, DBP and MBP.5.Peripheral vascular resistance (PVR) can be calculated from the equation PVR = BP/CO. This study was carried out on seventy normal healthy subjects, their age range (20-40 years) with mean Â± SD is (27.31 Â± 5.28years). In this study a totally non-invasive techniques were used during all phases of VM. Concerning the responses in different phases of VM we found that there is sudden increase of BP with reflex bradycardia at the onset of straining(phase1). During phase2 (straining phase) there is significant reduction of SV and decreasing of BP to the low point lead to sympathetic stimulation and reflex tachycardia and increment in BP(systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean blood pressure (MBP), so phase 2 can be divided in to phase 2E and phase 2L. At release of strain of VM, there is transient reduction of SV and BP (phase3), phase 2E and phase 3 were not included in this study as BP changes need to be measured by invasive technique. few seconds after release of strain, the SV return to premaneuver level with BP â€œover shootâ€ (increased SBP, DBP and MBP) and peripheral vascular resistance (PVR) also increased as it is calculated from this equation (PVR = MBP/CO), and there is reflex bradycardia so cardiac output(CO) is decreased (phase4).

Abstract:

The study aim was to explore the effects of multisensory breastmilk interventions on short-term pain of infants during newborn screening. This is a randomized controlled trial. A total of 120 newborns were recruited and assigned by randomization to one of three treatment conditions: Condition 1 = routine care (gentle touch + verbal comfort); Condition 2 = breastmilk odor + routine care; or Condition 3 = breastmilk odor + taste + routine care. Pain was scored with the Neonatal Infant Pain Scale (NIPS). Data were collected from video recordings at 1 min intervals over the 11 phases of heel sticks: phase 1, 5 min before heel stick without stimuli (baseline); phase 2 to phase 6 (during heel stick); and phase 7 to phase 11 (recovery). Generalized estimating equations compared differences in pain scores for newborns over phases among the three conditions. Compared with the routine care, provision of the odor and taste of breastmilk reduce NIPS scores during heel sticks (B = −4.36, SE = 0.45, p < 0.001 [phase6]), and during recovery (B = −3.29, SE = 0.42, p < 0.001 [phase7]). Our findings provide new data, which supports the use of multisensory interventions that include breastmilk odor and taste in combination with gentle touch and verbal comfort to relieve pain in infants undergoing newborn screening.

Abstract:

Abstract The study objective was to determine effects of Saccharmyces yeast postbiotics (CT; celluTEIN; Puretein Bioscience LLC, Minneapolis, MN, USA) on growth performance and carcass characteristics of pigs fed an increased protein diet during growing and finishing. Pigs [PIC Camborough×PIC 337; n = 51 barrows; 57 gilts; initial body weight (BW) 28.3 ± 0.1 kg] were weighed, stratified by BW within sex, and within each two-pig strata, randomly assigned to a pen (n = 18; n = 6 pigs/pen). Pens were randomly assigned one of two dietary treatments (Diet) consisting of 0 or 100 ppm CT mixed in a four-phase dietary regimen (phase1 d 0 to 21, phase2 d 22 to 42, phase3 d 43 to 63, phase4 d 64 to 84). Weekly, feed consumption and pigs were weighed to calculate performance. On d 91, 98, and 105, the heaviest male and female from each pen was harvested and carcass data were collected. Performance data were analyzed as a completely randomized design, carcass data were analyzed as a randomized complete block design, and pen was the experimental unit). Statistical significance was determined at P ≤ 0.05 and tendencies were declared between 0.05< P < 0.10. At all four phases, there was no Diet effect on BW, average daily gain (ADG), and average daily feed intake (ADFI; P > 0.12), except CT pigs consumed less (P = 0.04) feed during phase4. There was no Diet effect on Phase2 gain to feed ratio (G:F), but CT pigs had greater Phase1 and 4 G:F and smaller Phase 3 G:F (P < 0.04). From d 0 to 84, there were no Diet effects on ADG and ADFI (P > 0.13), but CT pigs had greater (P = 0.02) G:F. celluTEIN carcasses tended to have greater (P = 0.09) weight and had greater (P < 0.01) dressing percent than control carcasses. There were no Diet effects for 10th or last rib fat thickness, but CT carcasses tended to have less (P = 0.07) first rib fat thickness. There were no Diet effects on loin eye area, National Pork Board (NPB) color score, Japanese color score, and L*, a*, and b* values (P > 0.24). celluTEIN carcasses had smaller NPB marbling and Japanese marbling color scores than control carcasses (P < 0.02). When supplemented to an increased protein diet, Saccharmyces yeast postbiotics improve feed conversion while positively affecting several important carcass measures.

Abstract:

The sloshing phenomenon is one of the free surface flow that can endanger liquid cargo carriers such as ships. Sloshing is defined as the resonance of fluid inside a tank caused by external oscillation. When sloshing is close to the natural frequency of the tank it could endanger ships. Particle method has the advantages to be applied because sloshing is dealing with free surface. One of the particle methods is Smoothed Particle Hydrodynamics (SPH). In this study, compressible SPH was used as a result of the pressure oscillation, which exists because of the effect of density fluctuation as nature of weakly compressible SPH. To reduce pressure noise, a filtering method, Low Pass Filter, was used to overcome pressure oscillation. Three pressure sensors were used in the sloshing experiment with a combination of motions and filling ratios. Only one pressure sensor located in the bottom was used to validate the numerical results. A set of SPH parameters were derived that fit for the sloshing problem. The SPH results show a good agreement with the experiment’s. The difference between SPH and experiment is under 1 % for sway, but a larger difference shows in roll. Low pass filter technique could reduce pressure noise, but comprehensive method needs to develop for general implementation.

Abstract:

An important feature of batch process data is that many batch processes have multiple phases. Many different phased-based monitoring methods had been proposed. The key question of those methods is how to divide the phases of batch process. However, PCA-based methods of phase division that identify phases by extracting the first principal component of each time slice lead easily to high misclassification. In order to overcome the shortcoming of PCA-based methods, a novel phase-division method based on dissimilarity index is proposed. In proposed division method, integral information of each time slice is used to divide phases. The phase-based PCA is built in each phase to monitoring Penicillin fermentation process in order to verify performance of proposed method. The simulation results show that the proposed method is able to detect process faults more prompt and accurate than single MPCA model.

Abstract:

The modeling of phased-mission systems is difficult and the solving process is complex because of the relevance of the phase tasks and the sharing of components existing in different phases or between phases. To solve the problem, based on the cumulative exposure model, the path sets combination method of phased-mission systems is proposed. Aiming at the problem of the cross-stage correlation of components and its different failure rate in each phase, the cumulative exposure model considering the historical damage of components is used to solve by obtaining the cumulative damage distribution of each component in each phase. Firstly, a phased-mission systems reliability model is build by mapping phased-mission system fault trees into a Bayesian network. By traversing the Bayesian network, the minimal path sets of each phase are obtained. Secondly, the disjoint formulas introduced by variable elimination method are used to do the disjoint operation of the minimal path sets of each phase and the conditional probability relations of the common components are used to reduce the minimal path sets scale. Finally, the minimum disjoint path sets of each phase are combined and summed according to the component conditional probability relation. The path sets combination method of phased-mission systems avoids the large conditional probability table, large storage and large computation problems caused by the excessive discrete states in the traditional Bayesian method and the problem that the PMS-BDD method has strict requirements for variable ordering and is difficult to solve the system reliability with multiple failure distribution types of components. In the end, a phased-mission systems reliability modeling and solving is carried out for a geosynchronous orbit satellite, and compared with the PMS-BDD method, which verifies the correctness of the method.

Abstract:

Phase absence is a very common and severe problem in any industry, home or office. Many times one or two phases may not be live in three phase supply. Because of this, many times, some electrical appliances will be on in one room and OFF in another room. This creates a big disturbance to our routine work.This project is designed to check the availability of any live phase, and the load will be connected to the particular live phase only. Even a single phase is available, and then also, the load will be in ON condition.This project is designed with Arduino MCU. This controller continuously checks for live condition of all phases connected to it, and the controller connects the load to the active phase using a Relay. This relay is driven with a transistor. If two or three phases are live, the load will be connected to phase I only. An LCD is provided to display the status of the phase condition. Contrast control preset is given for LCD contrast control. This project uses regulated 12V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.

Abstract:

In this paper, a four unit cell micron-sized magnetic particles embedded composite right/left-handed (CRLH) transmission line metamaterial phase shifter is proposed. The variable phases are achieved by activating the micron-sized magnetic particles along the length of stub transmission lines of the CRLH transmission line structure. This causes to effectively change the inductance of stub transmission lines, which changes the phase of the RF signal. These structures can be activated in a symmetric or asymmetrical manner to obtain wide range of phase shifts. A prototype of cascaded four unit cell CRLH transmission line phase shifter with embedded silver-coated ferrites (magnetic particles) is designed, fabricated and tested for phase shifters applications. The measured phase response of the proposed phase shifter is in close agreement with the simulated phase response. Next, for the performance analysis of proposed phase shifter, a 1 × 4 conformal curved-shaped phased array operating at 5.8 GHz is fed with the four unit cell cascaded phase shifter in CST full-wave simulator. The conformal phased array with proposed integrated phase shifters was simulated for broadside pattern correction and main beam scanning at 20 degree on curved-shaped surface with different bend angles. The radiation pattern results obtained with the proposed integrated phase shifters are in close agreement with those obtained with direct excitation of the array.

Abstract:

Abstract In Inconel 783 alloy, there are mainly two kinds of strengthening phases of β and γ’. In addition, it is found that there are other precipitated phases in the alloy’s β phase. By means of multiple testing methods, the types and functions of the precipitated phase in the β phase were determined. The results showed that the precipitated phases from β phase were nanoscale Nb and Ti carbides and a large number of white needle-like Laves phases. The former, due to its small size, which can improve the grain boundary slip resistance of the alloy, thus improves the shaping of the material. While the latter, due to its sharp shape and due to its large amount, destroys the original structure of the β phase and greatly reduces the room temperature plasticity of the alloy.

Abstract:

Using complex of physicochemical methods of analysis (DTA, XRD, MSA, as well as measurements of density and microhardness), the phase equilibria in the Sb2S3-Cr2Se3 system was studied and a phase diagram was constructed. It is established that the system is quasi-binary and has eutectic type T-x diagram. In the process of chemical interaction, a compound with composition Cr2Sb2S3Se3 is formed in the system. The Cr2Sb2S3Se3 compound melts incongruently at 6500C., A limited area of the solid solution based on the initial components of the system is formed. The coordinates of the eutectic formed between the α-solid solution and the Cr2Sb2S3Se3 compound is 17 mol % Cr2Se3 at 4500C. At room temperature, solid solutions based on Sb2S3 reach up to 5 mol % Cr2Se3, and based on Cr2Se3 up to – 3 mol % Sb2S3. According to the results of X-ray diffraction analysis, Cr2Sb2S3Se3 crystallizes in a tetragonal system with lattice parameters: a=16.37; c=11.69 Å, ρpuc.=5.40 q/sm3, ρX-ray=5.42 q/sm3. The temperature dependence of the electrical conductivity and thermo-EMF of the (Sb2S3)1-x(Cr2Se3)x (x=0.01; 0.02; 0.03;) solid solution has been studied

Abstract:

Abstract The TIGER-3 radar is being developed as an “all digital” radar with 20 integrated digital transceivers, each connected to a separate antenna. Using phased array antenna techniques, radiated power is steered towards a desired direction based on the relative phases within the array elements. This paper proposes an accurate phase measurement method to calibrate the phases of the radio output signals using Field Programmable Gate Array (FPGA) technology. The method sequentially measures the phase offset between the RF signal generated by each transceiver and a reference signal operated at the same frequency. Accordingly, the transceiver adjusts its phase in order to align to the reference phase. This results in accurately aligned phases of the RF output signals and with the further addition of appropriate phase offsets, digital beamforming (DBF) can be performed steering the beam in a desired direction. The proposed method is implemented on a Virtex-5 VFX70T device. Experimental results show that the calibration accuracy is of 0.153 degrees with 14 MHz operating frequency.

Abstract:

Abstract In Lamb wave-based structural health monitoring, amplitude damage imaging is commonly used because the defects feature can be easily amplified by summing all the response signals together. However, the grating and side lobes affect the imaging quality and blind areas further restrict the inspection area. Considering that the existing phase-based imaging algorithms are either unfit for dispersive Lamb wave or strict to many requirements to guarantee better performance, inspired by the absence of phase information in focusing phased array, a novel focusing phase imaging (FPI) method for Lamb wave phased array is developed. The main contribution of the paper is introducing the phase information to focusing phased array. By applying the inverse-dispersion effect to the excitation signals and the superposition operation, the energy can be focused at every inspection point. The phase damage index is constructed by directly measuring the degree of consistency and alignment of the instantaneous phases. The experiments for the circular and linear array under various excitation signals with multiple defects verify that the FPI is effective for both surface damage and through-hole damage. The proposed algorithm is superior for its ability in energy focusing for defects, the capability in suppression of grating and side lobes, strong anti-disturbance ability from boundary reflection, the nonexistence of imaging blind area, and its adaptability for various excitation parameters and array layout.

Abstract:

In both industrial and military fields, there is such a kind of complicated system termed as phased-mission system, which executes missions composed of several different phases in sequence. The structure, failure behavior, and working conditions of such a system may change from phase to phase. The duration of each phase of such a system involved is random and follows a probability distribution, and the system may suffer some events resulting in simultaneous failures of different elements with different probabilities. In order to guarantee such a system completes the phased-mission successfully, a selective maintenance model for random phased-mission systems subject to random common cause failures is proposed to optimally identify a subset of maintenance activities to be performed on some elements of the system. Thereinto, a novel analytic model is developed to estimate the probability of the maintained random phased-mission system successfully completing the phased-mission, and we compare it with a well-known Monte Carlo Simulation approach. Finally, the proposed selective maintenance model has been successfully applied to an artillery weapon system. Comparative analysis is carried out to compare the proposed model with the traditional ones, including selective maintenance models for deterministic phased-mission systems and deterministic single-phase mission systems. The results show that ignoring some mission properties (e.g. randomness and multiple phases) in selective maintenance optimization will lead to (1) incorrect system and mission modeling, (2) incorrect computation of the probability of the random phased-mission system successfully completing a mission, and/or (3) nonoptimal selective maintenance options.

Abstract:

We propose a new formula for the adiabatic Berry phase which is based on phase-space formulation of quantum mechanics. This approach sheds a new light onto the correspondence between classical and quantum adiabatic phases — both phases are related with the averaging procedure: Hannay angle with averaging over the classical torus and Berry phase with averaging over the entire classical phase space with respect to the corresponding Wigner function.

Abstract:

Quantum phase transition is one of the main interests in the field of condensed matter physics, while geometric phase is a fundamental concept and has attracted considerable interest in the field of quantum mechanics. However, no relevant relation was recognized before recent work. In this paper, we present a review of the connection recently established between these two interesting fields: investigations in the geometric phase of the many-body systems have revealed the so-called "criticality of geometric phase", in which the geometric phase associated with the many-body ground state exhibits universality, or scaling behavior in the vicinity of the critical point. In addition, we address the recent advances on the connection of some other geometric quantities and quantum phase transitions. The closed relation recently recognized between quantum phase transitions and some of the geometric quantities may open attractive avenues and fruitful dialogue between different scientific communities.

Abstract:

Abstract This study investigated the effect of Ca source and level on growth performance, nutrient digestibility, blood profile, and bone characteristics of weaned pigs. The experiment was operated for 4 weeks in 2 phases (phase 1, d 0 to 14; and phase 2, d 15 to 28). Two hundred and forty pigs were assigned to 4 treatments including 2 Ca sources (CaCO3 and CaCl2), and 2 Ca levels (Phase 1: NC, normal Ca, 0.6% and 0.5% in phase 1 and 2, respectively; LC, low Ca, 0.5% and 0.4% in phase 1 and 2, respectively). The average daily gain (ADG) was improved in weaned pigs fed the NC or CaCl2 diets, in phase 2. The overall result showed the greater ADG and gain to feed ratio in the NC and CaCl2 treatments. The digestibility of crude protein, Ca, and P was increased in the NC and CaCl2 treatments at phases 1 and 2. There was an interaction between Ca source and level, with the NC and CaCl2 treatments increased blood chloride content in phase 1, and decreased HCO3 and base excess content in phases 1 and 2. The concentration of blood chloride was increased in pigs fed the NC diet in phase 1. The hematocrit (phases 1 and 2) and electrolyte balance (phased 2) were decreased in the NC treatment compared with the LC. An increase in blood chloride content, and a decrease in HCO3, base excess, and electrolyte balance were observed in pigs fed with CaCl2 in phases 1 and 2. The bone-breaking strength, bone ash, Ca, and P were increased in pigs fed the NC or CaCl2 diets. In conclusion, CaCl2 can be an alternative for dietary CaCO3 due to greater growth performance, nutrient digestibility, and bone health. Moreover, decreasing dietary Ca is not recommended for weaned pigs.

Abstract:

Selective synthesis of specific phased nanomaterials via a green route is a promising yet challenging task. In the present work, the hexagonal and monoclinic phases of BiPO4:Ln3+ (Ln = Sm, Eu, Tb, Dy) were prepared via room temperature co-precipitation method. For adjusting the phase of the products, the prepared mediums selected were the most common solvents, i.e., water and ethanol. It was very important that the prepared mediums could be easily recycled and reused by evaporating the filtrate. The formation mechanisms of hexagonal in water and monoclinic in ethanol were investigated. Interestingly, the growth behaviors of these phases were quite distinct and thus gave rise to distinct morphology and particle size. The hexagonal phase possesses a rod-like morphology with diameters of 50–160 nm and lengths of 65–400 nm while the monoclinic phase consists of almost entirely irregular nanoparticles. Also, it was found that the bending and stretching vibrations of O–H and PO4 tetrahedra were quite different for the products prepared in water and ethanol. Moreover, it was found that the luminescence properties, including emission intensity, lifetime, quantum efficiency, and color, could be readily tailored through controlling the phase structures and microstructures. The results showed that the monoclinic phase exhibited superior luminescent performance to the hexagonal phase. The methodologies reported in this work were fundamentally important, which could be easily extended to large-scale synthesis of other phased nanomaterials for potential applications as electroluminescent devices, optical integrated circuits, or biomarkers.

Abstract:

The phase structure of neutral two-flavor quark matter at nonzero temperature is studied. Our analysis is performed within the framework of a gauged Nambu–Jona-Lasinio model and the mean-field approximation. We compute the free energy of the gluonic phase (gluonic cylindrical phase II) in a self-consistent manner and investigate the phase transition from the gluonic phase to the 2SC/g2SC/NQ phases. We briefly consider the phase diagram in the plane of coupling strength versus temperature and discuss the mixed phase consisting of the normal quark and 2SC phases.
