Pipeline Monitoring System: A Feasibility Study

Pipeline is a medium through which fluids can be transported from one location to another. It is basically used to efficiently transport liquid and gaseous commodities over long distances at a low cost. Water, regular gases, petroleum products, and liquid hydrocarbons are examples of transportable pipeline commodities. The need for an efficient and reliable pipeline system is increasing by the day as a result of the detrimental effect of unreliable ones on society. Failure can result in environmental pollution and explosions, which can destroy lives, properties, and the ecosystem; moreover, the cost of restoring the ecosystem to its origin or natural form may be very costly or nearly impossible. To this effect, there is a need for pipeline monitoring systems (PMS) that will manage the pipeline network against such detrimental effects. This paper review some of the existing PMS highlights their sensing techniques, merits, de-merits, and areas of possible applications either onshore (surface or underground pipelines) or offshore (underwater pipelines). It also highlighted key components of PMS and classified the existing PMS into direct and indirect sensing, based on the sensing medium employed in their various methodologies.
Final Affirmative Proof Starling’s Law Wrong and G Tube Hydrodynamic is the Correct Replacement: New Results and Critical Analytical Criticisms of Impactful Landmark Articles

There are 21 reasons affirming Starling law is wrong on both of its forces and equation. The main study based on which Starling’s hypothesis was transferred into a law has a serious experimental error that invalidates it conclusion. The Tree Branching Law corrects 2 widely received misconceptions on capillary physiology: “The capillary crosssection area is greater that the aorta” and “the speed of blood flow in lumen is very slow”

Factors affecting self-efficacy against hypertension self-care in hypertension patients: a scoping review

Increased hypertension as the main risk for premature death, stroke and heart disease in the world. Hypertension is called the "silent killer" some individuals with hypertension are not aware of this problem and may even have no signs or warning symptoms. Prevalence of >15 years of age hypertension in Indonesia. According to the World Health Organization (WHO) the symptoms that appear can include morning headaches, nosebleeds, irregular heart rhythms, changes in vision and ringing in the ears. Hypertension can cause rupture or blockage of arteries that supply blood and oxygen to the brain which can lead to stroke. Predictive factors for stroke risk include age, history of cardiac arrhythmia/atrial fibrillation, history of coronary heart disease/myocardial infarction, history of deep venous thrombosis/pulmonary embolism, history of migraines, history of hypertension, blood pressure grade 1, blood pressure grade 2, blood pressure grade. 3, taking antihypertensive medication, taking anticoagulant treatment, and being active smokers. However, high blood pressure grade 3 is considered the highest risk of stroke. This is in line with the results of the meta-analysis study that hypertension is a high risk for stroke with a pooled odds ratio (OR) of 3.50 (95% Confidence Interval (CI) = 3.18-3.85).
An Equation Simultaneously Encodes the Duality of The Mind and The Body

The mind-body problem is the central issue in both of philosophy and life science for several centuries. To date, there is still no conclusive theory to interpret the relation between the mind and the body, even just the mind alone. Here, we promote a novel model, a derived mathematic equation called the entropic system equation, to describe the innate characters of the mind and the mechanism of the mind-body coupling phenomenon. As the semi-open thermodynamic systems far from equilibrium, the living organisms could be logically considered as an entropic system. In the living organisms or the entropic systems, there also are three essential existing elements including mass, energy and information, in which the mind and the body are hypothetically coupled by free energy and entropic force.
Jet propulsion of a squid-inspired swimmer in the presence of background flow

Inspired by recent studies of a squid-like swimmer, we propose a three-dimensional jet propulsion system composed of an empty chamber enclosed within a deformable body with an opening. By prescribing the body deformation and jet velocity profile, we numerically investigate the jet flow field and propulsion performance under the influence of background flow during a single deflation procedure. Three jet velocity profiles, i.e., constant, cosine and half cosine, are considered. We find that the maximum circulation of the vortex ring is reduced at a higher background flow velocity. This is because stronger interaction between the jet flow and background flow makes it harder to feed the leading vortex ring. Regarding thrust production, our analysis based on conservation of momentum indicates that with the constant profile the peak thrust is dominated by the time derivative of the fluid momentum inside the body, while momentum flux related thrust accounts for the quasi-steady thrust. For the cosine profile, its peak is mainly sourced from momentum flux associated with the unsteady vortex ring formation. No prominent thrust peak exists with the half cosine profile whose thrust continuously increases during the jetting. For all the three jet velocity profiles, added-mass related thrust attributed to body deformation enhances the overall thrust generation nonnegligibly. Under the present tethered mode, the background flow has negligible influence on the thrust attributed to momentum flux and momentum change of the fluid inside the body. However, it indeed affects the over pressure-related thrust but its effect is relatively small. The overall thrust delines due to the significantly increased drag force at large incoming flow speed despite the rise of added-mass related thrust. Unsteady thrust involving vortex ring formation becomes more important in the overall thrust generation with an increased background flow velocity, reflected by larger ratios of the unsteady impulse to jet thrust impulse.
Isolation Enhancement between Ports of a Compact Ultra-wideband MIMO Antenna

In this paper, a novel compact multiple-input multiple-output (MIMO) antenna with enhanced port isolation is proposed for ultra-wideband (UWB) applications. The UWB MIMO antenna contains two coplanar annular monopoles etched on the front side of the FR-4 substrate. The dielectric substrate has a relative permittivity of 4.4 and a size of 80 mm × 40 mm × 1.6 mm. The irregular ground is printed on the back side of the substrate. In order to enhance the port isolation between the two monopoles, the expanded ground is exploited in the proposed design. In addition, the ground is etched with some slots to achieve good impedance matching. Both the simulated and measured results show that the proposed antenna achieves good impedance matching as well as high port isolation over the entire UWB band. Moreover, the proposed antenna has good spatial diversity characteristics. In summary, the proposed UWB MIMO antenna can be well applied to the ultra-wideband wireless communication system.
UKF-Based State Estimation for Electrolytic Oxygen Generation System of Space Station

Electrolytic oxygen generation system (EOGS) is the only system that can provide oxygen for astronauts in a physicochemical regenerative way in a long-term manned spacecraft. In order to ensure that the astronauts in the cabin can obtain a continuous and enough oxygen supply, it is necessary to carry out real-time condition monitoring and fault diagnosis of the EOGS. This paper deals with condition monitoring and fault diagnosis of the EOGS. Firstly, the dynamic model of the system is established based on the principle electrolysis for actual oxygen production system and the state observer of the system has been designed by using unscented Kalman filter (UKF). The total pressure in the cabin and the partial pressure of oxygen in the electrolytic cell can be observed. Then, considered the actual conditions of the manned space mission with one more astronaut, i.e., 3 astronauts, the simulation experiment is carried out. The simulation results show that the method can effectively estimate the system state, and it is of great significance to ensure the normal operation of the electrolytic EOGS system in the space station.
A new empirical equation to describe the vertical leaf distribution profile of maize

Abstract The characteristic traits of maize (Zea mays L.) leaves affect light interception and photosynthesis. Measurement or estimation of individual leaf area has been described using discontinuous equations or bell-shaped functions. However, new maize hybrids show different canopy architecture, such as leaf angle in modern maize which is more upright and ear leaf and adjacent leaves which are longer than older hybrids. The original equations and their parameters, which have been used for older maize hybrids and grown at low plant densities, will not accurately represent modern hybrids. Therefore, the aim of this paper was to develop a new empirical equation that captures vertical leaf distribution. To characterize the vertical leaf profile, we conducted a field experiment in Jilin province, Northeast China from 2015 to 2018. Our new equation for the vertical distribution of leaf profile describes leaf length, width or leaf area as a function of leaf rank, using parameters for the maximum value for leaf length, width or area, the leaf rank at which the maximum value is obtained, and the width of the curve. It thus involves one parameter less than the previously used equations. By analysing the characteristics of this new equation, we identified four key leaf ranks (4, 8, 14 and 20) for which leaf parameter values need to be quantified in order to have a good estimation of leaf length, width and area. Together, the method of leaf area estimation proposed here adds versatility for use in modern maize hybrids and simplifies the field measurements by using the four key leaf ranks to estimate vertical leaf distribution in maize canopy instead of all leaf ranks.
Women and men in the United Nations: A corpus analysis of General Debate addresses

The United Nations (UN) has demonstrated a commitment to women’s empowerment over seven decades of work. Yet gender inequality pervades in countries around the world and even within the UN. This corpus analysis investigated collocates of woman(’s), women(’s), man(’s) and men(’s) in 193 UN General Assembly General Debate addresses in fall 2015 to examine gender representation by international decision-makers. The analysis revealed that the plural women occurred more frequently than men and primarily in discussions on gender equality and violence. In contrast, the singular man was identified more frequently than woman, in generic use (e.g. mankind) and in references to eminent male leaders. Despite UN dedication to gender equality and linguistic guidelines promoting gender-inclusive language, these General Debate addresses do not conceptualise women and men equally, more frequently referring to women as a group in need of protection and support and to men as political figures and other distinguished individuals.
A unified solution for in-plane vibration analysis of composite laminated sector and annular plate with elastic constraints

A semi-analytical method for in-plane vibration analysis of a composite laminated annular and sector plate with elastic constraints is presented. The theoretical model is on the basis of a variational method and a multi-segment technique. Displacement variables are expanded by the Jacobian orthogonal polynomial. Boundary conditions and continuity conditions between segments are characterized by penalty parameters. On this basis, a series of numerical examples are given. The results show that the method has good convergence speed and accuracy. Finally, the parametric study of geometric and material parameters is carried out to provide important support for solving the in-plane characteristics of this kind of composite structure.
Wavelength-Dependent Nonlinear Absorption in Palladium Nanoparticles

This paper aims to study the nonlinear absorption characteristics of palladium nanoparticles (PdNPs) at off-resonant wavelengths. For this purpose, multi-wavelength (500–650 nm) nanosecond Z-scan technique was used. The experimental results indicate that saturated absorption (SA) and the transition from SA to reverse saturated absorption (RSA) can occur, and depends on the excitation wavelength and energy. When the excitation wavelength is constant, with the increase of excitation energy, PdNPs change from SA to RSA. When the excitation energy is constant, with the excitation wavelength approaching surface plasmon resonance (SPR), PdNPs change from SA to RSA. This phenomenon of SA and RSA under multi-wavelength excitation in the off-resonant region provides a supplement for the systematic study of the nonlinear absorption of PdNPs.
A ZnO–CNT nanocomposite based electrochemical DNA biosensor for meningitis detection

A zinc oxide (ZnO) and multiwalled carbon nanotube (CNT) based nanocomposite matrix has been fabricated onto indium tin oxide (ITO) coated glass (ITO/glass) platform via. A chemical route. The thiolated oligonucleotides probe sequence consisting of 23 bases (single-stranded DNA) has been immobilized onto the ZnO–CNT/ITO electrode using a physical adsorption technique. The fabricated bioelectrode (ssDNA/ZnO–CNT/ITO) is used to specifically detect N. meningitidis with a high sensitivity of 20.20 μA per decade and 45 s of hybridization time by differential pulse voltammetry (DPV) using methylene blue as an electroactive indicator. The prepared DNA biosensor exhibits linearity in a wide range (5–180 ng μl−1). The electrochemical impedance response behaviour of the ssDNA/ZnO–CNT/ITO bioelectrode with an increase in the target DNA concentration has also been studied using [Fe(CN)6]3−/4− as the hybridization indicator. The results indicate the possibility of fabricating a handheld device for meningitis detection at an early stage.

Consensus of discrete-time multi-agent systems with multiplicative uncertainties and delays

This paper studies the consensus problem of discrete-time single-integrator multi-agent systems with multiplicative uncertainties and bounded communication delays in switching networks. Some sufficient conditions for non-stochastic consensus are obtained by adopting the constant-gain protocol. For the case that the uncertainty is exponentially decaying (i.e. is with ), it is proved for any bounded delays, the consensus can be achieved if the switching topology is uniformly rooted. For the case that the uncertainty is polynomially decaying (i.e. is with ), under a precondition that the system state is bounded, a similar conclusion is also obtained. The convergence rate of the consensus protocol is quantified in terms of the decay rate of uncertainties. Simulation results are given to verify the correctness of the conclusion.
Degradation of PVC/rPLA Thick Films in Soil Burial Experiment

Some of the biodegradable polymers can be blended with a synthetic polymer to facilitate their biodegradation in the environment. The objective of the study was to investigate the biodegradation of thick films of poly(vinyl chloride)/recycled polylactide (PVC/rPLA). The experiments were carried out in the garden soil or in the mixture of garden soil and hydrocarbon-contaminated soil under laboratory conditions. Since it is widely accepted that the biosurfactants secreted by microorganisms enable biotransformation of various hydrophobic substances in the environment, it was assumed that the use of contaminated soil, rich in biosurfactant producing bacteria, may accelerate biodegradation of plastics. After the experimental period, the more noticeable weight loss of polymer films was observed after incubation in the garden soil. However, more pronounced changes in the film surface morphology and chemical structure as well as decrease of tensile strength were observed after incubation of films in the mixture of garden and contaminated soil. It turned out that as a result of competition between two distinct groups of microorganisms present in the mixture of garden and hydrocarbon-contaminated soils the number of microorganisms and their activity were lower than the activity of indigenous microflora of garden soil as well as the amount of secreted biosurfactants towards plastics.
Controls on Greenland moulin geometry and evolution from the
Moulin Shape model

Abstract. Nearly all meltwater from glaciers and ice sheets is routed englacially through moulins, which collectively comprise approximately 10–14 % of the efficient englacial–subglacial hydrologic system. Therefore, the geometry and evolution of moulins has the potential to influence subglacial water pressure variations, ice motion, and the runoff hydrograph delivered to the ocean. We develop the Moulin Shape (MouSh) model, a time-evolving model of moulin geometry. MouSh models ice deformation around a moulin using both viscous and elastic rheologies and models melting within the moulin through heat dissipation from turbulent water flow, both above and below the water line. We force MouSh with idealized and realistic surface melt inputs. Our results show that variations in surface melt change the geometry of a moulin by approximately 30 % daily and by over 100 % seasonally. These size variations cause observable differences in moulin water storage capacity, moulin water levels, and subglacial channel size compared to a static, cylindrical moulin. Our results suggest that moulins are significant storage reservoirs for meltwater, with storage capacity and water levels varying over multiple timescales. Representing moulin geometry within subglacial hydrologic models would therefore improve their accuracy, especially over seasonal periods or in regions where overburden pressures are high.

Intersections Between Awe and the Sublime: A Preliminary Empirical Study

This empirical study examines how philosophical work on the sublime relates to contemporary psychological work on awe. We operationalized several aspects of the sublime drawing from prominent philosophical theories and analyzed them in relation to three different measures of awe: the modified Differential Emotions Scale (mDES), the awe sub-scale of the Dispositional Positive Emotion Scale (DPES), and the Awe Experience Scale (AWE-S). We carried out an Exploratory Factor Analysis on our items on the sublime. We found high correlations between these items and the measures of awe, especially with the self-loss and connectedness dimensions of the AWE-S. By operationalizing aspects of the sublime drawn from influential philosophical theories and comparing them with psychological measures of awe, we find a large degree of overlap between awe and the sublime, suggesting that these two literatures could inform one another.
