Metal-loss defect depth inversion in oil and gas pipelines based on Bayesian regularisation neural network
Authors: Tu FengMiao , Wei MingHui , Liu Jun , Jiang LiXia , Zhang Jia
Published: December 2022

Defect depth inversion is generally considered as a challenge in magnetic flux leakage (MFL) testing and evaluation because of its strong non-linearity and low prediction accuracy. Current inversion models focus on the inversion accuracy of specific datasets, ignoring consideration
of the generalisation ability of inversion models under different conditions. In order to solve such problems, this paper proposes a novel pipeline defect inversion method based on a Bayesian regularisation neural network (BRNN) model. This method consists of two parts. Firstly, three domain
features are extracted and a Boruta algorithm is introduced to reduce the feature dimension and obtain the best feature subset. Secondly, in order to approximate the complex non-linear relationship between multi-dimensional features and defect depth, a back-propagation neural network (BPNN)
model based on Levenberg-Marquardt optimisation and a Bayesian learning algorithm is constructed. The model can effectively find a close global minimum and overcome the phenomena of overfitting and overtraining. In order to evaluate the performance of the proposed defect inversion method,
a comparative experiment is carried out with other well-known inversion algorithms. The results obtained confirm that the inversion method can improve the prediction accuracy of defect depth. More importantly, this method enhances the generalisation ability of defect inversion problems with
different sample sets.
Welding defect detection in nuclear power plant spent fuel pool panels based on alternating current field measurement: experimental and finite element analysis
Authors: Zhou Zhaoming , Yang Chunfu , Liu Liyan , Zhao Donghong , Li Kai
Published: December 2022

The overlay panels of spent fuel pools of nuclear power plants can easily become corroded and produce micro-crack defects. Surface crack defects tend to expand vertically, horizontally and obliquely, causing damage and fracture to the overlay panels and welds of spent fuel pools. Traditional
non-destructive testing (NDT) cannot complete underwater testing in real time. In order to improve the timeliness of crack detection and shorten the inspection period, research on accurate inspection technology for surface cracks in the overlay panels of spent fuel pools is carried out in
this paper based on alternating current field measurement (ACFM) and the weld defect detection process for the cladding panels of spent pools is optimised. In this work, different types of artificial defect are assumed and the distortion of the magnetic field characteristic signal caused by
the defects is studied. The characteristics of magnetic field signals generated in different defect regions are studied by establishing a defect electromagnetic detection model for numerical calculation. Finally, experimental and numerical results are compared and analysed. The results show
that ACFM can be used to quickly and effectively inspect for cracks in the base material, weld and interface of spent fuel pool overlay panels and it has the characteristics of accuracy, high resolution, high sensitivity and low delay. The research results, which have good application value,
provide technical support for electromagnetic inspection of latent cracks in field spent fuel pools and early crack warning of underwater structural defects.
In-situ fatigue damage monitoring of rolled Al-Zn-Mg alloy using an advanced acoustic emission technique
Authors: Zhu Rong Hua , Chi Da Zhao , Zhan Xiao Hong
Published: December 2022

In the present study, damage evolution in rolled Al-Zn-Mg alloy and its welds is evaluated using the acoustic emission (AE) method and crack initiation is detected using digital imaging during fatigue tests. The AE characteristics and source mechanisms are analysed based on microstructural
and fractographic observations. The experimental results show that AE energies are effective indicators for detecting fatigue crack initiation in Al-Zn-Mg alloys. The results obtained were verified through digital images of the notch tip region of the Al-Zn-Mg alloy samples. For small percentages
of the applied load range close to the peak load, the AE count rates show a reasonable correlation with the crack propagation rates. These correlations can be applied to predict the remaining service life of fatigue-damaged structures. The analyses performed demonstrate that the AE technique
is sensitive to variations in the fracture mode and could be applied to monitor fatigue damage evolution in welded structures.

Effect of Operating Conditions on Modified Kalina Cycle Performance
Authors: Nassir Abdulkhodor Kathum , Shahad Haroun A.K.
Published: December 2022

Simple Kalina cycle system (SKCS) is used for low temperature, intermediate temperature and high temperature heat recoveries. However, its efficiency is rather low. Therefore, a modification is suggested to improve its efficiency. In this work a computer program is developed to predict the energy-exergy performance of a modified Kalina Cycle System (MKCS) using aqua ammonia solution. It consists of heat recovery vapor generator (HRVG), condenser, heat exchanger, separator, turbine, throttling valve, absorber and pump. The modification is implemented by introducing a heat exchanger (HE) between the separator and expansion valve. This HE is used to reheat the work solution which comes from the pump by the high temperature hot weak solution which comes from the separator. The effect of many operating conditions such as dryness fraction (DF) at separator inlet, low pressure and ammonia (NH3) mass fraction with constant high pressure on cycle performance is studied. The results show that the modified cycle efficiency is higher than the simple cycle efficiency by about 33.6% while the net power by about 27.8%. The highest efficiency and highest net output power are 14.7% and 0.5641 kW respectively. The exergy efficiencies for modified Kalina and simple Kalina are 24.8% and 11.7% respectively.

Published: December 2022

It is of practical significance to analyze the time-sharing and zoning heat load demand and fine heating control of large heating buildings in order to reduce the building energy consumption. The existing research lacks the time-sharing and zoning form of refined heating for different functional zones of large heating buildings. For this reason, this paper carried out the time-sharing and zoning heat load demand analysis and research on heating control of large heating buildings. First, the mathematical model for the main heating links of the heating system of the large building based on the heat balance equation is constructed to realize the simulation of the dynamic change of the performance of the large building heating system. Then, the size, characteristics and influencing factors of heat load of various heating units in the building are analyzed, and three possible ways of mass regulation, mass-flow regulation and intermittent regulation that can change the flow by stages are introduced. The experimental results verify the effectiveness of the proposed heating control mode, which can effectively reduce the building heating energy consumption.

Published: December 2022

The dynamics of MHD non-Newtonian fluid flow past a cylinder with slip boundary condition and magnetic field is addressed in this study. The non-Newtonian fluid (tangent hyperbolic) considered in this study are nail polish and whipped cream. This article investigates the statistical analysis of two-dimensional MHD tangent hyperbolic fluid flow over a cylinder with slip condition. The partial differential equations describing the problem are later transformed into the ordinary differential equation by similarity variables. The derived model is solved by the spectral homotopy analysis method (SHAM). The characteristics of the parameters of the flow are demonstrated by the velocity of the flow. The skin friction coefficient is computed and presented with the aid of a tables. The slope of the linear regression is obtained through the data points while bar charts for engineering quantities of interest are presented. The findings indicated that an increase in magnetic parameters builds a resistance to the flow. Also, it was discovered that the radius of curvature decreases when the curvature parameter increases.

Published: December 2022

MHD effect using micropolar fluid between rough conical bearings is analyzed in this paper. The Reynolds equation is derived in the form of magnetic field using the Eringen principle with Christensen theory. The stochastic modified Reynolds equation for two types of one-dimensional structure, the radial roughness pattern and azimuthal roughness patterns is derived for micropolar fluid. In terms of dimensionless pressure, load carrying capacity and time, the numerical results are presented. The importance of roughness, MHD and micropolar fluid is greater than that of the classical Newtonian case. From the analysis, the impact of micropolar fluid and electrically conducting fluid increases the load carrying capacity further decreases the time relative to the Newtonian instance. On the whole, the squeezing film characteristics of conical bearings is improved for higher values of coupling number and Hartmann number.

Studying industries energy saving is very important prospect for many researchers in the last four decades. In this respect, better process heat transfer can be achieved to improve process operating and capital cost. Thereafter, obtaining higher amount of heat recovery, which will help to reach system optimum heat exchanger network design. Application of Pinch analysis (PA) in our current study, was found to be as an effective method towards economic solution and assessment for all system thermal processes. Whereby, minimizing energy losses, and thus, prediction of maximum energy saving. In addition, application of "Aspen Energy Analyzer (AEA)" simulation software assist our effort to optimize Heat Exchanger Network design (HEN), with various application scenario towards best design. This study represents a "Case study" as a Brayton closed cycle gas turbine power plant in Al-khairat district, which is one of a number of sites used to generate electricity for Iraq national grid. However, the plant original design is open cycle. This study, represent an attempt to apply (PA) in system closed cycle model with the same working conditions. The results predicted, on the contrary of open cycle, that using closed cycle (PA) with temperature difference ∆Tmin can be acceptable with several design propositions. The optimum (∆Tmin = 15℃) were evaluated in the closed cycle system pinch analysis, thereby the maximum Qrec. process that minimize the QHmin & QCmin requirement were identified by the software simulation for the best HEN design. These results were found as Qrec. = 318.330 MW, QHmin = 88.607 MW and QCmin =39.564 MW.

Published: December 2022

This study presents numerical solution by using coupling model between computational fluid dynamic (CFD), and finite element method (FEM) to predicted the temperature distribution through cutting tool. In this study ANSYS/Explicit dynamic used to solve finite element equations in cutting zone. Machining simulations were conducted using Aluminum (AL) and High speed steel (HSS) as a workpeice and tool material respectively. Depth of cut varied from 1.5 mm to 2.5 mm and a cutting speed varied from 6m/s to 10m/s have been considered in the simulations. The CFD model solve by using ANSYS/fluent to find the temperature distribution at the tool surface by using finite volume method. The simulation explained the influence of depth of cut, and cutting speed on cutting temperature. For all simulations, the rake angle is fixed (6°). The rise or reduction in temperature as a result of the various cutting parameters was also estimated and discussed. After solving the problem, it was discovered that the temperature at the tip (tool-work piece contact area) was the highest and gradually decreased towards the surface, and that the results showed a major influence of cutting speed on the temperature generated in the machined models and a very small influence of depth of cut on the workpiece temperature.

Published: December 2022

An experimental investigation on the performance of an air conditioner and its operating conditions under constant outdoor moisture content and varied dry-bulb temperature has been accomplished. The test was conducted on an air conditioner using R32 with a nominal cooling capacity of 2.6 kW and the test was carried out in a controlled and standardized test room. During the test, the outdoor temperature was varied from 24 to 36℃ while maintaining the humidity ratio at 14.9 kg vapor per 1 kg of dry air. The indoor compartment was maintained at 27℃ dry-bulb temperature and 19℃ wet-bulb temperature. Generally, as the temperature of outdoor air increases by 1℃, the input power increases by 1.4%, the cooling capacity decreases by 0.9%, and the coefficient of performance decreases by 1.95%. In addition, the outdoor air temperature has a more significant effect on the refrigerant discharge and liquid line temperature than that of refrigerant suction temperature.

The present work investigates experimentally and numerically the combustion of methane coupled to biodiesel and diesel in dual fuel mode. The engine used is a single-cylinder Lister-Petter_01005299_TS1 modified for bi-fuel operation with a pre-chamber in the intake to allow methane to enter with the air. For this, we use three distinct fuels, conventional D100 diesel, B100 biodiesel and methane. The first two fuels are first burned independently under the same conditions independently under the same conditions using the double Wiebe phase. The numerical results obtained of this first combustion of B100 and D100 compared to the measured results show an agreement of 2% and 1.07% respectively for biodiesel and diesel allowing the validation of the numerical code. Next, we add methane to the air during the intake phase for the previously tested D100 and B100 fuels used as a pilot fuel in order to observe the impact of methane on cylinder pressure, nitrogen oxide emissions and heat release. The combustion model used is a two-zone 0D, one representing the burnt gases and the other the unburnt gases. The results showed a decrease in cylinder pressure and a large reduction in nitrogen oxide emissions of about 26.67% and about 48.76% when burning B100 biodiesel at medium load. The results also showed that the addition of methane to the air reduces the overall heat release of both fuels around TDC by 10.76% and 5.4% for biodiesel and diesel, respectively. But that in the diffusion phase, dual fuel combustion shows a higher heat release for diesel. It was also observed that peak pressures were reduced by 2.35% in the case of diesel compared to 7.45% for biodiesel.

Published: December 2022

The process of fuel droplet evaporating is one of the most important factors that directly affect the efficiency of the combustion process. Therefore, the current study reviews previous studies that focused on the process of evaporation of a drop of fuel. The review is divided into points. The first part is concerned with modeling of the evaporation process under different initial condition and temperature of the droplet. The second part present the experimental studies concerned with measuring the evaporation time of the droplet, as well as the shape of the droplet during the evaporation process. Most of the studies related to this subject can be divided into three categories: The first category is the studies that are concerned with the process of heating the droplet and studying the evaporation time for different types of fuels or by adding nanomaterials to the fuel and studying their effect on the evaporation process. The second category is the studies concerned with the mechanics of droplet evaporation and the study of droplet shape. The third category is the studies that focus on studying the effect of initial conditions, such as temperature and pressure, as well as the concentration of gasses surrounding the drop and their types. There are other studies concerned with projecting the electric field onto the drop during the evaporation process and studying its effect.

Reconstructing the origin among the descendants of naturalized voltaic immigrants Ivorians in Bouaflé
Authors: Houedin Barnabé
Published: December 2022

This article aims to examine the strategies of reconstruction of the "Mossi" origin among the descendants of naturalized immigrants in Bouaflé. The qualitative data obtained are the result of a series of individual and collective interviews. At the end of the study, it appears that the processes of reconstruction of origin appear as practices aimed on the one hand to escape the ethnic control induced by the anteriority on this reception area and on the other hand to strengthen the quests for autonomy orchestrated through the claim of native status.These practices are carried out concurrently and implicitly following units of action between naturalized villages. They also hide mechanisms aimed at enhancing the identity of native groups among the local native groups. This essentially involves symbolic and economic resources such as the legitimization of the "Mossi electorate", the strengthening of expressions of citizenship in the direction of the autonomy of naturalized villages and the appropriation of land.
Cascading Impacts of Change in Carbon Dioxide Concentration, Temperature and Precipitation on Horticulture Crops: A Review
Authors: Pawar Pandurang , Sakhale Bhagwan
Published: December 2022

The impacts of an increase in carbon dioxide concentration, temperature and precipitation on physiology, yield and biochemical contents of horticulture crops including its mitigation measures are evident globally. This study mainly focuses on South-East Asia and Africa. We have reviewed crop-wise published literature mainly from 2000-2021 regarding the impacts of rising carbon dioxide concentration, temperature and precipitation on horticulture. Visible phenophase changes in horticultural crops such as budburst, leaf initiation, flowering, fruiting, seedling and the overall development stages of the crops are evident from the available literature. The prevalence of many diseases like blight, mildew, abaca, black sigatoka and Pierce’s disease are the results of climate change. Changes in the biochemical content of the horticulture crops such as tannins, flavonol, alcohol level, acidic content, starch, amino acids, lipids, chloroplasts, sugar, organic acids and antioxidants were observed. The recommended mitigation measures throughout the literature are delayed sowing dates, efficient seed varieties, controlled fertilizer use, soil moisture conservation and other biotechnological measures. Salinity, moisture and environmental stress-tolerant crops need to develop for better management of climate change. Breeding of short-duration and heat-tolerant varieties, vulnerability quantification and early warning disease forecasting are some of the important research areas.

Published: December 2022

Background: Due to increased price of soybean meal, dairy farmers are seeking suitable and viable alternate protein supplement to soybean meal for economic ration formulation. Thus, a study was conducted to evaluate the effect of inclusion of cottonseed meal (CSM) as an alternate protein source in growing buffalo calves. Methods: A total of 12 buffalo calves aged approximately 6-12 months with 149.88±9.93 kg average body weight were randomly assigned to three treatment groups with four calves each, designated as control (C), T1 and T2 groups. Soybean meal (SBM) in concentrate mixture fed to C group was replaced by cottonseed meal (CSM) at 75 and 100% level on w/w basis in T1 and T2 groups, respectively. The duration of study was 120 days. Result: The digestibility of nutrients in T1 and T2 groups was similar to of C group. The total nitrogen intake, N outgo and N balance varied non-significantly among C, T1 and T2 groups. The blood metabolites and cell mediated immune response in T1 and T2 groups were similar to that of C group. The average daily gain in T2 group was numerically higher than other groups. It was concluded that CSM could replace SBM upto 100% on w/w basis in the concentrate mixture without any adverse effect on growth, nutrient utilization, blood biochemical profile, cell mediated immune response and growth of calves.

When using ascorbic acid coated hernioimplant, less pronounced reactive changes were observed in the surrounding tissues, manifested by the absence of a significant number of inflammatory cells, the predominance of fibroblastic elements in the field of view, the activation of which contributed to the early engraftment of the hernioimplant as a result of stimulation of collagenesis. Therefore, it was concluded that the most optimal is hernioimplant coated with ascorbic acid.

Despite the improvement of the technique of surgery and treatment, the frequency of complications after appendectomy with an atypical location of the appendix varies from 10 to 30 %. The aim of the work is to evaluate the effectiveness of the use of regional lymphostimulation and ozonated solutions in the prevention of complications after appendectomy with an atypical location of the appendix. Materials and methods. 45 patients with an atypical location of the appendix were subjected to analysis (a prospective study). 2 groups were identified: the first (comparison group) included 21 patients who underwent process removal and traditional treatment in the postoperative period. The second, main group, included 24 patients who had regional lymphostimulation, irrigation of the process bed and the operating wound with an ozonated sodium chloride solution at the time of surgery. Results. In the comparison group, there was suppuration of the wound in 4, and infiltration in 2, intestinal paresis in two and early adhesive intestinal obstruction in one. A relaparotomy was performed. In the main group, one suppuration and infiltration of the postoperative wound were noted. There were no fatal outcomes. Conclusion. The use of regional lymphostimulation and ozonated solutions can reduce the frequency of complications and the length of hospital stay in acute appendicitis with an atypical location of the appendix.

The inflammatory reaction that arises in patients with sepsis is interconnected with the coagulation system and leads to the development of hypercoagulable changes in the body. Therefore, in this study, we studied the effect of direct oral anticoagulants dabigatran etexilate and apixaban on the hemostasis system without and under conditions of a systemic inflammatory response. Hypercytokinemia was created by intravenous administration of lipopolysaccharide into the tail vein of a rat. The anticoagulant activity of the studied drugs was assessed by their effect on the parameters of the rat blood coagulogram. Dabigatran etexilate showed a pronounced antithrombin effect, increasing the thrombin time by 10.5 times relative to the control in intact animals. Under conditions of hypercytokinemia, this activity increased by 12.8 times. Apixaban did not cause changes in thrombin time, but it increased the prothrombin time index both in intact animals and animals with a systemic inflammatory response by 7 and 8.6 times, respectively. Thus, an increase in the anticoagulant effect of dabigatran etexilate and apixaban under conditions of hypercytokinemia indicates that they may have anti-inflammatory activity.

Introduction. Sodium benzoate is widely used in both food and pharmaceutical industries. There is evidence of its adverse health effects; However, the effect of sodium benzoate on the ultrastructure of thyroid gland cells is currently not well understood. Materials and methods. The animals were divided into two groups: the group 1 was injected with 1 ml of sodium benzoate solution at a dosage of 1000 mg/kg/body weight intragastrically for 60 days, and the group 2 served as a control. Samples of thyroid gland after tissue processingwere examined under an electron microscope. Results. In the experimental group, it was found that thyrocytes had a cubic, less often flat shape, an expanded rough endoplasmic reticulum with single accumulations in the cavities of fibrous structures, significant lumps of heterochromatin under the nuclear membrane with uneven contours of the latter, an electron-dense mitochondrial matrix. Conclusion. The above changes indicate the effect of sodium benzoate administration both locally (through damage to the DNA of the nucleus and mitochondria) and at the systemic level (through a decrease in leptin levels and, as a consequence, the effect on the hypothalamic-pituitary-thyroid axis).

Retinated wisdom teeth, especially on the lower jaw, are still the subject of discussion by most specialists and, especially, orthodontists. The aim of the work was to determine the indications for orthodontic treatment of semi-trained wisdom teeth on the lower jaw and to evaluate the effectiveness of the measures taken. 12 people with semi-trained wisdom teeth on the lower jaw were examined and treated. The diagnosis of the position of the teeth was evaluated according to the orthopantomogram, on which the lines were applied, and the stress axis was determined, which is a guideline for choosing a treatment method. In this method, tangent lines were drawn to the branch and the body of the lower jaw, which formed an angle at the intersection. The bisector of this angle served as the boundary between the branch and the body of the jaw (stress-axis). The indication for orthodontic treatment was the location of the wisdom tooth in front of the stress axis. In this case, the conditional median vertical of the wisdom tooth, as a rule, intersected with the tangent line to the body of the lower jaw in front of the mandibular angle, regardless of its size.

The aim of the work was to evaluate the clinical profile of patients and the frequency of cardionephroprotective therapy in chronic glomerulonephritis (CGN) with hypertensive form (GF), the presence of chronic kidney disease (CKD) and associated clinical conditions. Material and methods. Patients with HF CGN, 102, men - 52, women - 50, (55,0 ± 11,84) years, and stage III EAG, 98, men - 45, women - 53, (64,45 ± 12,1) years, were examined, the diagnosis was verified in the Tver Region Regional Clinical Hospital. Results. Differences in the frequency of associated clinical conditions, stages of CKD and the administration of hypotensive, lipid-lowering and antiplatelet drugs were revealed between patients with HF CGN and EAG. Conclusions. The clinical profile of patients with GF CGN consists of stage 3b-4-5 CKD, CVB, DM, the clinical profile of EAG patients includes stage 1-2-3a CKD, CVB, DM, CHF and CHD. Cardionephroprotective therapy in patients with GF CGN consists in the early inclusion of lipid-lowering and antiplatelet drugs in therapy before the appearance of stage 3b CKD, CVB and always in the presence of DM.
