Authors: Aned Ashham Mohammed , Raheemah Saddam Hussein , Fadheel Kareem Idan
Published: May 2022

In this study, computational analysis has been carried out using computational fluid dynamics (CFD). These calculations have been made to investigate the rheological behavior of the mixed-phase flow in horizontal pipelines. In order to study the shear stress in a vertical pipe, a new numerical model for oil-water dispersion in three dimensions has been developed. CFD software has been used to study the wall shear stress function and water droplet pressure. Using Reynolds numbers and the Navier-Stokes equations with k–turbulence factor to save energy, the flow range for the continuous process was explained. The results from a recent study on experimental methodology were simulated. In this study, the diameter of the tube is 40 mm and the length is 3.5 m and modeled and analyzed using Ansys software. Thus, the geometry has been imported and modeled using the CFD tool. The meshed model has been tested and converged accordingly. The primary data of the simulation have been verified with experimental results successfully. Oil droplet widths have previously been thought to be dependent on the flow Reynolds number, which was confirmed in this case study. Droplet diameter Dd was measured at 6 mm while the mixture moved at a speed of 1.9 m/s. It was found that the largest shear stress value was found at the top of the pipe, where the oil fraction (cut-off) was 0.3, in the simulation results for varied velocities (1.6, 2.5, 2.9 m/s) and oil fraction (cut-off) values. The results of the simulation analysis of the two-phase flow of crude oil for the horizontal pipe are wall shear stresses with different velocities for crude oil in the two-phase flow. As well as pressure drop at different velocities for the same fluids

Published: May 2022

In this study, the effect on the series prediction of the financial system of the central library has been investigated and analyzed accordingly. Four models have been conducted to analyze the series prediction of the library as well as to investigate the monthly income. These models included the Seasonal indexing model (SIM) and Prediction of ARIMA model (PARIMA). Furthermore, Poisson logarithmic linear model has been applied for all suggested models accordingly. The results based on the given models have been verified based on Heteroskedasticity Test. Six months have been included beginning with Jan and ending with Jun. According to the statistical analysis, the verification method used the Heteroskedasticity test. The results revealed that the three models have been verified and were ready to be employed in the next step of the procedure. The PARIMA model has a maximum R2 of 2.7. A certain effective model was employed to predict time series for the used period (Jan to Jun). At these indexations, the lag value has reached a maximum of 0.98. In April, the correlation reached 0.344. Seasonal indexation values for the chosen time have been explained (six months). The figures shifted from month to month. According to the investigation, the highest degree of indexation occurred in April and the lowest level occurred in June. The linear Poisson logarithmic distribution has been explored and examined. At the SIM model, the standard error was reported within the maximum level of 0.3. From the beginning of the year through the end of the year, six months have been documented (X1 to X6). The month of March was the most deviant. In January, the residual Dif has achieved its greatest value of 0.092

Published: May 2022

This paper proposes a step-by-step technique for combining basic models that forecast electricity consumption in an artificial neural network by the method of preliminary selection and further hybridization. The reported experiments were conducted using data on hourly electricity consumption at the metallurgical plant AO ArcelorMittal Temirtau in the period from January 1, 2019, to November 30, 2021. The current research is related to the planned introduction of a balancing electricity market. 96 combinations of basic models were compiled, differing in the type of neural network, the set of initial data, the order of lag, the learning algorithm, and the number of neurons in the hidden layer. It has been determined that the NARX-type network is the most optimal architecture to forecast electricity consumption. Based on experimental studies, the number of hidden neurons needed to form a planned daily profile should equal 3 or 4; it is recommended to use the conjugate gradient method as a learning algorithm. When selecting models from three groups, it was revealed that the conjugate gradient method produces better results compared to the Levenberg-Marquardt algorithm. It is determined that the values of the selected RMSE error indicator take values of 23.17, 22.54, and 22.56, respectively, for the first, second, and third data groups. The adaptive hybridization method has been shown to reduce the RMSE error rate to 21.73. However, the weights of the best models with values of 0.327 for the first group of data, and 0.336 for the second and third ones, show that the individual use of a separate combination of models is also applicable. The devised forecasting electricity consumption model can be integrated into an automated electricity metering system

Published: May 2022

The subject of this study is indicators of the quality, geometric accuracy, and roughness of holes in aviation structures (AS) made from polymeric composite materials (PCM) produced by drilling. The indicators of quality, geometric accuracy, and roughness of PCM holes were investigated by using kinematic hole drilling schemes and the creation of PCM chips. A kinematic scheme has been built of the cutting forces operating in PCM when drilling with the distribution of zones from 0° to 360°. Experimental studies on the establishment of characteristic shrinkage zones in the drilling of PCM, as well as their values, have been implemented. The methods used are the analysis of the quality indicators of PCM holes, and the method of expert assessments. The following results were obtained. Based on the analysis and synthesis, it was found that with incorrectly selected geometric parameters for drills involving the work accompanied by the wear of drills on the back surface, stratification, cracks, or chips of PCM may appear. It is shown that the decisive factor is a comprehensive assessment, which is determined not only by the quality, accuracy, and roughness but also by the condition of the holes at the input and output of the drill. Features and characteristic contact zones for PCM drilling were identified. It has been established that within the drill operating areas from 0° to 90° and from 180° to 270° the cutting forces are reduced while the indicators of surface quality, roughness, and geometric accuracy of a PCM hole are improved. In zones from 90° to 180° and from 270° to 360° – on the contrary, low quality of the machined surface is assumed. The calculation of the required cutting forces and calculation of the height of roughness of drilling holes in PCM have been proposed, taking into consideration the bearing of chips under the action of the wedge. The results of experimental studies on the establishment of characteristic shrinkage zones when drilling PCM confirmed the adequacy of the results of theoretical studies on the kinematic schemes of drill operation in PCM
Improving the strength of composite material through the effective modification of the surface of the cellulose filler
Authors: Kurmanbekova Elmira , Sambetbayeva Aigul
Published: May 2022

An effective technique has been devised in order to increase the strength of arbolite, based on the method of rice husk thermal treatment. Given the fading of the surface layer of the grains during thermal exposure, the accompanying elements are removed from the outer cellulose fibers of the husk structure, that is, the texture of the surface of the material changes. It is known that the strength of multicomponent materials depends on the strength of bonds between the structural elements and the strength of the elements themselves. In arbolite, the strength of the constituent elements is great but the strength of arbolite almost does not exceed 2.5–3.5 MPa. Therefore, one of the factors determining the strength of arbolite is the adhesion strength of its heterogeneous particles. Therefore, a necessary and mandatory condition for the preparation of rice husks is soaking them in water, as well as the use of chemical additives for their treatment. This study's results established that the surface of the modified rice husk is chemically more active than without treatment. The use of chemical additives made it possible to neutralize the effect of extractive aggregates on cement due to the formation of additional chemical bonds in the contact zone and reduce their toxic effect on cement when removed from this zone. As a result of thermal exposure, a new potential property is revealed in the rice husk, which is expressed in the modification of the husk by changing the texture of its surface, which, when mixed with cement, enhances the adhesive adhesion of the surfaces. The rice husk thermal treatment method was employed to increase the class of arbolite to B 2.0 in terms of compressive strength, that is, arbolite of structural purpose was obtained, used as load-bearing structures in low-rise construction

Published: May 2022

Biscuits are common snacks, which have a wide variety of flavors. With the enhancement of modern health awareness, regular biscuits with high sugar, oil, fat and low protein cannot meet the demand of customers. Customers need more healthy biscuits in the market. In this study, pumpkin seed meal, konjac along with low-gluten wheat powder were used as the main material and maltitol was added as a sweetener to make a kind of healthy biscuits with high protein, high dietary fiber and low sugar. Pumpkin seed meal is a by-product of the oil production from pumpkin seed, which has high protein content. Pumpkin seed protein is composed of albumin, globulin, glutenin, and proline. It contains high-quality protein and necessary amino acids for people. Konjac is rich in dietary fiber, which can promote intestinal peristalsis. Maltitol is a healthy sugar substitute. Both of them have a low calorie level. In this study, the effects of the addition ratio of the main material (low-gluten wheat powder, pumpkin seed meal, and konjac powder), the addition ratio of plant oil and butter, and the addition amount of maltitol on the flavor and hardness of the biscuits were analyzed by a single-factor test. Besides, the orthogonal test was conducted, and the results showed that the optimal formula was the ratio of the main material (low-gluten wheat powder, pumpkin seed meal, and konjac powder) of 2:1:1, the amount of plant oil and butter of 4 % and 12 %, and maltitol amount of 20 %. According to the nutritional determination, the pumpkin seed meal biscuits contain 20.4 % protein, 18.0 % fat, 1.8 % ash, 59.2 % total carbohydrate (including 19.1 % dietary fiber and 40.1 % available carbohydrate), and 0.6 % water

Published: May 2022

The interaction of fine particles with an expanding gas flow under fluidization conditions is considered. The objects of study are finely dispersed materials, their single particles, gas flow in a fluidized layer. The study used the laws of dynamics and hydrodynamics, the classical laws of mechanics, as well as mathematical methods for the analytical solution of equations. It is emphasized that when a particle moves upwards in a gas jet, three forces act on it: the resistance force Fc, the gravity force P, and the Archimedes force A. As a result, the motion of a fine particle in an expanding gas flow is described taking into account the law of dynamics. During the study, an analytical equation was obtained to determine the velocity of a particle during its rise and fall in a gas jet. During the study, an analytical equation was obtained to find the height of the particle ascent depending on the gas flow rate for given geometric parameters of the gas flow. The obtained formulas can be used in the process of studying the process of convective drying of finely dispersed materials for various design parameters of the dryer. In practice, as a rule, there are various empirical formulas that describe such interactions of particles for specific parameters, which make it difficult to generalize them. In this work, the correctness of the assumed conditions necessary for the analytical solution of the differential equation of particle motion is proved. As a result, formulas were obtained that make it possible to determine the velocity of a particle in a gas jet and the height of its rise depending on the gas flow rate. On the basis of these formulas, graphic dependences of the gas velocity in the jet on the height Vg=f(Z), as well as the dependences of the height of the particle rise hm on the air flow rate in the jet L at different jet expansion angles α=15°; α=20°; α=30° are plotted. It was found that with an increase in the height Z in an expanding jet, the gas velocity in the jet Vg decreases, with an increase in the air flow rate in the jet L, the height of the particle rise hm increases. These formulas are the basis for further consideration of the movement of particles in a fluidized layer in the process of convective drying of fine materials for its intensification of the drying process
Technology for programming contour milling on a CNC machine
Authors: Petrakov Yuriy , Korenkov Volodymyr , Myhovych Artur
Published: May 2022

This paper reports a new technology for designing control programs for contour milling on CNC machines. The technology enables stabilization of the cutting process along the entire contour at the optimal level by controlling the feed, which ensures an increase in productivity when meeting the requirements for restrictions. Moreover, the effectiveness of using the technology improves with an increase in the complexity of the contour by changing the curvature of the surface. A mathematical model has been built for the interaction between the cutter and workpiece in the cutting zone when machining contours with variable curvature, which makes it possible to determine the main characteristic of the cutting process – the rate of cutting the allowance. The technology involves the use of a control program in G codes designed in any CAM system. At the first stage, a shape-formation trajectory in the form of a two-dimensional digital array is derived from the program. At the second stage, the cutter workpiece engagement in the cutting area is modeled simulated while determining the main characteristic of the cutting process – an analog of the material removal rate. And at the final stage, the simulation results are used to design a new control program, also in G-codes, with a new recorded law to control the feed, which enables the stabilization of the cutting process along the entire milling path. The software for the new technology has been developed, which automatically converts the preset control program in G-codes into a two-dimensional digital array, simulates the milling process, and designs a new control program in G-codes based on its results. The results of the experimental study into the milling of the preset contour using the developed simulation program showed an increase in productivity by 1.7 times compared to the original control program, designed in a conventional CAM system

The object of research is the process of thermal degradation of oil sludge in the presence of heterogeneous catalysts.
The creation of efficient technological processes for processing the organic part of oil sludge into motor fuels, raw materials for petrochemicals and the disposal of microsilicate is an important urgent task, the solution of which will allow to obtain a significant economic and environmental effect. The problem to be solved is to establish the general kinetic laws of the process of thermal degradation of oil sludge in the presence of microsilicate with deposited metals. The advantage of the Ozawa– Flynn–Wall method is that it is possible to determine the kinetic parameters for each value of oil sludge conversion, that is, for different stages of thermal degradation. The activation energy of oil sludge 67.1 kJ/mol, and with a catalyst 59 kJ/mol are calculated for each degree of conversion (α), respectively. The value of the correlation coefficient was (R2≥0.997) provides good convergence with experimental results. Compared with other methods of thermal processing of oil sludge, catalytic thermal degradation has a number of advantages: relatively low process temperatures (400–650 °C), low sensitivity to the composition of raw materials and the processing process, which meets all modern requirements of chemical production.
Regularities of thermokinetic parameters of thermal decomposition of oil sludge were studied using raw materials obtained during the process of oil transportation, in the presence of catalyst with applied metal (nickel, iron, cobalt) to microsilicate. Obtained results of oil sludge decomposition kinetics can be used in creating a database for mathematical modeling of process of heavy hydrocarbon raw materials processing
Improvement of noisy images filtered by bilateral process using a multi-scale context aggregation network
Authors: Hussein Zinah R.
Published: May 2022

Deep learning has recently received a lot of attention as a feasible solution to a variety of artificial intelligence difficulties. Convolutional neural networks (CNNs) outperform other deep learning architectures in the application of object identification and recognition when compared to other machine learning methods. Speech recognition, pattern analysis, and image identification, all benefit from deep neural networks. When performing image operations on noisy images, such as fog removal or low light enhancement, image processing methods such as filtering or image enhancement are required. The study shows the effect of using Multi-scale deep learning Context Aggregation Network CAN on Bilateral Filtering Approximation (BFA) for de-noising noisy CCTV images. Data-store is used tomanage our dataset, which is an object or collection of data that are huge to enter in memory, it allows to read, manage, and process data located in multiple files as a single entity. The CAN architecture provides integral deep learning layers such as input, convolution, back normalization, and Leaky ReLu layers to construct multi-scale. It is also possible to add custom layers like adaptor normalization (µ) and adaptive normalization (Lambda) to the network. The performance of the developed CAN approximation operator on the bilateral filtering noisy image is proven when improving both the noisy reference image and a CCTV foggy image. The three image evaluation metrics (SSIM, NIQE, and PSNR) evaluate the developed CAN approximation visually and quantitatively when comparing the created de-noised image over the reference image.Compared with the input noisy image, these evaluation metrics for the developed CAN de-noised image were (0.92673/0.76253, 6.18105/12.1865, and 26.786/20.3254) respectively

Authors: Mandsorwale Deepti , Sharma Bindu
Published: May 2022

The aim. To access the superiority of myeloperoxidase & oxidized low-density lipoproteins over each other acts as a better predictive marker gaining information regarding the severity of cardiovascular disease.

Materials and methods. 215 subjects are taken into consideration of which 54 are healthy controls, 52 are from stable angina pectoris, 53 are taken from unstable angina pectoris and 56 subjects are from acute myocardial infarction. Lipid profile parameters, oxidative stress markers, plasma myeloperoxidase and plasma oxidized low density lipoproteins were estimated by kit methods, thiobarbituric acid reactive substances method, and colorimetric assay, sandwich and competitive enzyme linked immunosorbent assay techniques, respectively. Results were present as mean ± SD, p-values <0.05 as significant, and Student’s unpaired “t” test. Comparative analysis by box and whiskers plot to check skewness and deviations within the values. Data analysis was performed by software package SPSS version 17.0.

Results. The oxidized low density lipoproteins levels found significantly elevated in all three cases subgroup contrary to insignificant levels of myeloperoxidase in stable angina pectoris compared to control. Box and whisker plot of myeloperoxidase levels showed no skewness in stable angina pectoris (non-significant), whereas unstable angina pectoris and acute myocardial infarction showed right skewness (highly significant), whereas plots of oxidized low-density lipoproteins show extensive interquartile range in the stable angina pectoris subgroup, suggesting scattered deviation in the mean values compared to unstable angina pectoris and acute myocardial infarction subgroup.

Conclusions. The study concluded that significantly elevated level of oxidized low-density lipoproteins in stable angina pectoris, unstable angina pectoris, and acute myocardial infarction subgroups with a scattered deviation of oxidized low density lipoproteins levels in the stable angina pectoris subgroup reflects its low prognostic reliability compared to plasma myeloperoxidase with marginal deviation and in insignificant elevation in stable angina pectoris. Thus, plasma myeloperoxidase and oxidized low density lipoproteins levels serve as independent predictors of cardiovascular disease, but plasma myeloperoxidase levels predict an increased risk over oxidized low density lipoproteins for subsequent cardiovascular events in stable and unstable angina and extend the prognostic information gained from traditional biochemical markers

Authors: Proshchenko Olha , Ventskivska Iryna
Published: May 2022

The study examined the development of posthysterectomy syndrome in patients after hysterectomy with preservation of ovarian tissue.

The aim of the study was to assess the functionality of ovarian tissue in patients with hysterectomy and opportunistic salpingectomy performed for uterine fibroids.

Materials and methods of the research. The study was performed in 160 women of reproductive age. The first group included 90 patients after vaginal hysterectomy with tubectomy and associated with laparoscopy, the second group - 70 patients after abdominal hysterectomy with tubectomy. The control group included 50 women of reproductive age 45.7±1.3 years with asymptomatic fibroids. The diagnostic algorithm included assessment of hormonal status and instrumental study of structural and functional parameters of ovarian tissue both at the stage of preoperative observation and for 12 months, 3 and 5 years after surgery.

Research results and their discussion. At the preoperative stage in both groups found a higher percentage of thyroid disease, hypertension and metabolic disorders, as well as combined proliferative processes of the uterus. Normal ultrasound picture of the ovaries was found in 67.8 % - in the first group and in 47.1 % - in the second group. Significant increase in blood flow in the ovarian artery, in the remote period showing atrophic changes with the development of ovarian depletion syndrome. Assessment of hormonal status in both groups shows marked changes in baseline levels of gonadotropic hormones (FSH and LH): increase in baseline FSH levels by 2.2 times, LH - 1.5 times against the control group (p <0.05), dyshormonal disorders persist for up to 5 years after surgery in one third of cases, and up to 36 months - there is an increase in the proportion of cystic and trophic changes, most pronounced in patients with reduced ovarian reserve, dysmetabolic manifestations and combined proliferative processes of the uterus and appendages before surgery, and syndrome chronic pelvic pain and venous pelvic blood supply in the postoperative period.

Conclusions. The technique of performing a hysterectomy does not have a significant effect on the functional state of the ovaries in the long term. The main indicators of ovarian blood flow and steroid hormone production after hysterectomy with opportunistic salpingectomy for uterine fibroids are close to the reference values up to 36 months postoperatively

Dicamba-Resistant Crops – Stumbling Over the Starting Block
Authors: Dayan Franck E.
Published: May 2022

The discovery phenoxy herbicides (i.e. 2,4-dichlorophenoxyacetic acid or 2,4-D) in the 1940s ushered in a new the era of weed management. Since then, the agrochemical industry has developed and commercialised a wide panoply of herbicides with at least 25 recognised mechanisms of action.
Today, farmers rely heavily on the use of chemicals for controlling weeds. The process of discovering, developing and commercialising herbicides has been successful because of the mostly positive interactions between researchers from industry, academia and governmental institutions. This process
has been self-correcting, where new compounds initially discovered by companies were made available to independent researchers outside industry to evaluate in their specific geographic location to identify potential weaknesses or problems that needed to be addressed before global commercialisation
of a product. This system has worked well for industry, researchers, farmers and consumers, except for where dicamba use with dicamba-resistant crops is concerned. Dicamba (3,6-dichloro-2-methoxybenzoic acid) is a group 4 (auxin mimic or growth regulator) herbicide of the methoxybenzoic acid
group. Group 4 herbicides mimic the action of auxin (indoleacetic acid). Their actual mechanism of action is fairly complicated, but in short, they bind to the receptor for auxin and disrupt normal hormonal regulation of cell growth, leading to abnormal growth and death of plants. Because
auxin mimics tend to provide selective control of broadleaf weeds in grass crops, these herbicides were initially very popular for broadleaf weed management in corn and related cereals. Dicamba was first introduced in the US in the mid-1960s and was used for that purpose successfully for many
years.

With around 40 crore consumers in need of sustainable mobility by 2030, India is the fifth - largest automotive market and has the possibility of becoming one of the top three in the coming years. Nevertheless, in light of the Paris Agreement's aims, a growth in the number of automobile
users will not result in a rise in traditional fuel usage. In order to accomplish India's Net Zero Emissions objective of 2070, a transit transformation is required. This will result in more "availability," as well as improved transport links. Many of these "faster mileage"
will very certainly be electric vehicles. Electric automobiles are the new frontier, according to a growing consensus among auto experts and the broader population. However, India, among other things, has a long approach in terms of battery manufacturing and charging facilities . This review
throughs the light on how non-renewable and renewable sources takes part in Co2 emission and how the world in comparison to India is moving towards electrical vehicles.
Phyllanthus Emblica (Indian Gooseberry) in the prevention of cancer
Authors: De Mukhopadhyay Keya
Published: May 2022

Medicinal plants have been considered to be precious natural gifts to human beings that could promote disease-free life. Indian gooseberry or Amla, scientifically known as Phyllanthus emblica, is a tree abundantly found in the tropical and subtropical regions of Southeast Asia.
The fruit of Phyllanthus emblica is rich in vitamin C, flavonoids like quercetin and rutin, and polyphenols like tannins, gallic acid, and ellagic acid, etc. Research reports suggested that Amla is possessed with important neuroprotective, cardio-protective, gastro-protective, nephronprotective,
and chemo-preventive properties. Cancer is currently a global epidemic with an estimated 19.3 million new cancer cases and approximately 10.0 million cancer deaths taking place in 2020. The societal impact of such a staggering number of deaths is immense when we think of the quality of human
life and the economy. So undoubtedly we need new, promising and effective therapies for common cancers. In recent years the potential of Amla as an effective anti-cancer agent has been scrutinized through many studies and there is certainly evidence to show that Amla extracts can be used as
an anti-tumor and cancer preventive agent. In this article, we focus on the anti-cancer properties of Indian Gooseberry or Amla.

This paper gives the first description of the male drumming call of Besdolus ventralis. Based on the examination of a single male specimen of this rare stonefly species its male call is composed of 3 beat groups, each containing 3-6 beats repeated at decreasing interbeat intervals. Beat groups are separated by 184-212 ms intergroup intervals. Call duration varied between 496-549 ms at ambient air temperature 18.7-20.4 degrees of Celsius. These results show that the male call of B. ventralis is clearly different from the diphasic call of B. ravizzarum, and is rather similar to that of B. bicolor, which is the closest relative of B. ventralis regarding mitocondrial DNA sequences. The main difference between the male calls of the two species seems to be that B. ventralis produces 3-6 beats per group, while B. bicolor is reported to produce only 2 (rarely 3) beats per beat-group.
Aspiration Risk Factors in Hospitalized Patients Following Trauma

Introduction. Risk factors for aspiration are not well characterized in the trauma patient population.  Improved understanding is important due to features of this patient population that place them at high risk for morbidity and mortality with aspiration. 
Methods. In a retrospective analysis of a select group of patients who suffered a traumatic injury, candidate and significant associations were identified for aspiration events.
Results. Of the 146 patients analyzed, 57 (39%) had at least one documented aspiration event while 89 (60.9%) patients had none.  Multivariate logistic regression found a significant association between impaired consciousness and aspiration events (p = 0.012).
Conclusions. To our knowledge, this study is a novel characterization of trauma patients likely to have experienced an aspiration event while hospitalized.  Our results suggest candidate risk factors for aspiration exist in a trauma-specific population.  Impaired consciousness is likely to show a significant association with aspiration in trauma patients in future studies.
Analysis of the organisation's borrowed capital

Subject. Due to increasing competition and an increasingly complicated social and economic environment, capital configuration in organisations requires a very flexible approach. The corporate tradition of relying only on the company’s own funds can result in many rapidly disappearing business opportunities being missed while operating based on mainly borrowed resources can result in unjustified risks to the company's solvency and financial stability. A comprehensive analysis of how borrowed capital is used is necessary for making informed and immediate decisions with regard to raising capital and structuring it. As a result of the state’s policy to increase transparency and digitalise the economy, many sources of information about the activities of organisations have become publicly available. These data allows conducting a comprehensive analysis of how the borrowed capital is used. Purpose. Developing recommendations for the analysis of the borrowed capital of organizations using open data. Methods. The research results were obtained using analysis, synthesis, analogy, classification, and other methods and approaches. Results. The article continues the discussion about the meaning and content of the term “borrowed capital”; it justifies a rejection of using the category “attracted funding” for the purpose of economic analysis; it proposes a methodological approach to the comprehensive analysis of the organisation’s borrowed capital; it demonstrates the procedure for such analysis and the interpretation based on the example of a telecommunication company and with a due consideration of the peculiarities of the current social and economic situation. Conclusions. The proposed recommendations for the analysis of borrowed capital are universal and can be applied in organisations outside the public and financial sectors that produce standard (not simplified) financial statements and annual reports.

Hypothesis The degree of transparency and reproducibility of economic health analyses, whether primary studies or systematic reviews and meta-analysis, which are used for development could condition the usefulness of clinical practice guidelines in which they are included regardless of the methodological quality of them. Objectives Primary objective Analyze the relationship between the methodological quality of clinical practice guides published in Spain and the current state of reproducibility and transparency of the health economic assessment studies included in them, both primary studies or systematic reviews and meta-analysis. Secondary objectives Evaluate the quality of CFCs produced in Spain in the period 2000-2020. Evaluate the methodological quality of the economic assessment studies included in the GPCs produced in Spain in the period 2000-2020. Describe the transparency and reproducibility of the selected economic assessment studies. Analyse whether there are differences in transparency and reproducibility of economic assessment studies depending on the quality of the GPCs that include them. Analyse whether there have been improvements in the transparency and reproducibility of economic assessment studies by comparing the GPCs containing them that have been produced in 2000-2012 vs 2013-2020.
