Abstract Internal audit as a form of implementation of a management audit has a general purpose to provide recommendations for improvements to company management programs or activities. This community service activity (PKM) is carried out at Universal Trading Surabaya, which is a trading company with commodity products with very complex business processes. The purpose of carrying out an internal audit is to maintain service and product quality as a mandatory clause in ISO 9001: 2015 certification. The target of this activity is that company employees are able to carry out a series of ISO audit surveillance activities which have been carried out every six months since 2017. PKM activities are carried out intensively in the form of intensive training for approximately a month, namely in January 2020. From the results It is hoped that the partners will be able to carry out the internal audit process on a regular basis as a concrete form of the company's commitment to maintaining work quality from a quality management system perspective.

Innovative development of domestic enterprises and growth of their competitiveness is the most important task at the present stage of development of the country's economy. The purpose of this study is to develop methodological tools that assess the impact of strategic plans for innovative development of an enterprise on the level of its competitiveness. The hypothesis of the study is that the plans for innovative development of the enterprise have a positive impact on the level of competitiveness of the enterprise. The article shows that in modern conditions one of the main directions of increasing the competitiveness of any company is inextricably linked with the formation and use of innovative development systems at enterprises. An analytical review of the existing methods for evaluating the competitiveness of the enterprise is carried out; their advantages and disadvantages are determined. It is shown that there is currently no single universal approach to such evaluation. As a result, a reasonable choice was made in favor of a methodological approach that evaluates competitiveness in dynamics; the main indicators and algorithms used in this approach are presented. The method of assessing the stability of the competitive position of industrial enterprises based on their innovative activity using a number of innovative indicators and taking into account their possible growth in the financing and implementation of innovative projects is proposed. The competitiveness of the largest Russian Pipe Metallurgical Company in comparison with its leading domestic competitors in the period 2017-2019 was evaluated; the main problems and weaknesses in the company's activities that have a negative impact on its competitiveness are identified. An assessment of the innovative activity of the Pipe Metallurgical Company is performed, which shows that the company currently adheres to a strategy based on the introduction of improving innovations. Modeling of the dependence of the level of the competitiveness of the company on the indicators of its innovation activity is performed; the indicators that have the strongest impact are identified, namely: the coefficient of intellectual property security, the coefficient of innovative growth, and the coefficient of development of new products. An example of the implementation of an event aimed at increasing the company's innovation activity indicators and related to the commissioning of unique research equipment for the development of new threaded connections for pipes is given. Based on the projected outcomes of the event, the forecast level of competitiveness of the Pipe Metallurgical Company for the period up to the end of 2020 was determined.

This article examines industrial paternalism in Finland throughout a century, from the 1880s to the 1980s, and coincides with the rise and decline of industrial society in the history of Western capitalism. The focus of the article is on social relationships between management and employees in an ironworks in Billnäs, located in south-western Finland, and how it developed and changed during the studied time period. Applying a microscopic historical analysis, this article looks at universal phenomenon, namely concerning social relations and gender in the world of industrial paternalism in concrete detail. In addition to a historical understanding of paternalism, the article also contributes to a broader understanding of the relationship between social and economic relations in paternalist organizations with a view to exploring the cultural understandings of gender and class.

Purpose The purpose of this study is to document the concrete practices put in place by United Nations Global Compact (UNGC) affiliated firms and their application of the UNGC Communication on Progress (COP). Design/methodology/approach The paper examines the practices implemented by firms on the Fortune 500 list that have affiliated with the UNGC and issued a COP separate from their annual report or a sustainable development report. According to the UNGC, the COP policy sets out a description of practical actions the company has taken or plans to take to implement the ten principles. Findings The findings tend to show that firms affiliated with the UNGC use a variety of practices to integrate these principles. Many adopt policies based on an international standard relating to a UNGC principle. However, the reporting process supported by the UNGC does not seem to fully promote the widespread application of these practices. Originality/value The documentation of these practices will serve as a reference for any business interested in adopting the UNGC principles or for government and non-government organisations, including accounting standard setters, aiming to promote and support the universal principles on human rights, labour, the environment and anti-corruption. In addition, the study reveals weaknesses in the UNGC COP policy that could limit more extensive application of these practices.

Transportation agencies are currently challenged to keep up with culvert infrastructure that is rapidly deteriorating due to lack of adequate maintenance and capital improvement. It is imperative for the transportation agencies to identify and rehabilitate deteriorated culverts prior to their failures. Among several concerns, lack of rational rehabilitation prioritization tools is foremost. Complicating this need further, current practices vary widely across the state departments of transportation (DOTs) which makes it difficult to develop a universal approach for prioritizing failing culverts. This paper presents and demonstrates a failure risk-based culvert prioritization approach that is compliant with the inspection procedures of the South Carolina DOT. The approach presented in this paper is specifically developed for reinforced concrete pipe (RCP) and corrugated metal pipe (CMP) materials because of their wide popularity. Outcomes from a survey of state DOTs informed the development of parametric weightings using the principles of analytical hierarchy process (AHP). Weightings developed for several critical inspection parameters are combined with the corresponding condition assessment scores to determine the failure criticality of culverts, which are subsequently combined with estimated failure consequences to determine failure risk estimates. The prioritization approach is demonstrated using the condition assessment scores of over 5200 culvert structures in South Carolina.

The modern approach to the design of road culverts involves the use of computeraided design (CAD). In design organizations of Ukraine software products of the Minsk company CREDO are being used for calculations of capacity of culverts by GRIS_T. Since 2019, the UKRRVS program is being developed to calculate culverts of road structures according to Ukrainian standards. At the moment, the program has the calculation of stormwater runoff according to MADI/SoyuzDorProekt formula and meltwater runoff (according the Road Handbook). In 2020, a new stage of automated calculation of road culverts started - calculations of capacity. The article presents the automated calculation of road reinforced concrete round culverts for pressureless operation. Goal. It is proposed to automate the calculation of road reinforced concrete round culverts for pressureless oper-ation. Methodology. The current methods for calculating the throughput of reinforced concrete road culverts have been used. Programming was carried out in the C# language using object-oriented programming. Results. The state of affairs in the auto-mation of hydraulic calculations in the road industry in accordance with Ukrainian standards was analyzed. It was concluded that at the moment the production uses the GRIS program of the CREDO company. The UKRRVS program is being developed. In this program, the issue of automating the calculation of the throughput of round culverts for operation in freeflow mode is relevant. The question of the methodology and algorithmization of this calculation, coding and interface support has been resolved. Practical value. The algorithm for calculating road culverts has been developed. A part of calculating the throughput of road culverts has been created in the UKRRVS program. This part covers the most com-mon group - round reinforced concrete culverts for freeflow operation. Originality. The interface has been created for the automation program for calculating road culverts. When you click the button “Round reinforced concrete pipes” in the main menu of the program UKRVS 21, the window “Calculation of a round reinforced concrete pipe operating in pressureless mode” opens. The calculation consists of three parts: the area of formation of initial data, the button “Calculate”, and the area of output of results of calculations. The area of formation of ini-tial data consists of 7 points. The area of the results of calculation of round reinforced concrete road cul-verts working in a pressureless mode consists of 14 points.

Due to the insufficient radial stiffness of the steel tube, the cracking of the weld and the plastic deformation of the string often occur under the cyclic loading of the hollow section pipe joint. In order to avoid such a failure, the overlapped K-joints were strengthened by pouring different concrete into the chords. Furthermore, to explore the detailed effect of filling different concrete in a chord on the hysteretic behavior of the overlapped K-joints, six full-scale specimens were fabricated by two forms, which included the circular chord and braces, the square chord and circular braces, and the low cyclic loading tests, which were carried out. The failure modes, hysteretic curves and skeleton curves of the joints were obtained, and the bearing capacity, ductility and energy dissipation of the joints were evaluated quantitatively. The results showed that plastic failure occurs on the surface of the chord of the joints without filling concrete, while the failure mode of the joints filled with concrete in the chords was the tensile failure of the chords at the weld of the brace toe, and the compressive braces had a certain buckling deformation; The strengthening measures of concrete filled with chord can effectively improve the mechanical properties of the K-joints, the delay of the plastic deformation of the chord, and improve the bearing capacity of the K-joints. Contrarily, the ductility coefficient and the energy dissipation ratio of K-joints decreased with the concrete filled in the chord. The hysteretic behavior of the K-joints with a circular chord and brace was slightly better than that of the K-joints with a square chord and circular brace, and the hysteretic behavior of the K-joints strengthened with fly ash concrete, which was better than that of the K-joints strengthened with ordinary concrete. The results of ANSYS (a large general finite element analysis software developed by ANSYS Company in the United States) analysis agreed well with the experimental results.

The analysis of the dynamics of the corrosion processes of the lining and concrete trunk of the chimney, depending on the operating conditions and climatic conditions, reveals the conditions for the formation of initial cracks in the lining, the dynamics of their growth, it is shown that, with a density of hair cracks of 10 pieces on an area of 0.5 m2, so permeable that the rates of local corrosion processes of lining and concrete materials create an excessive risk of destruction of the chimney. Especially quickly the degradation processes the chimney is exposed at a point about one-third of the top at gas velocities below 10 and above 20 m/s. Excessive permeability of the lining as an additional critical defect is suggested to be taken into account in the composition of critical defects in the traditional classification of their hazards, and its identification is to be based on the results of recognition of defects in photographs obtained by monitoring the chimney with an autonomous device — by the parameter “exceeding the density of cracks by opening width 1 mm and more than 10 pieces on an area of 0.5 m2. At the same time, in the analysis of the risk of destruction of the chimney, the event tree is complemented by the fourth branch, which means the emergence of a critical defect — excessive permeability of gases through the lining. In addition, the lengths of cracks in the lining and concrete trunk are referred to the diameter of the pipe, which makes the classification more universal.

This article seeks to analyze the public policies implemented by the Government of the Federal District (GDF), aimed at the homeless population. Despite the recognition of the fundamental nature of social rights by the 1988 Federal Constitution and the Universal Declaration of Human Rights, such acts still need concrete measures to materialize their provisions. To carry it out, the descriptive research method and secondary data obtained by the Federal District Planning Company (CODEPLAN) in 2022 were used, which outlined the profile of the homeless population in the Federal District. The difficulty in implementing public policies in the Federal District is also reported. The research showed that the coronavirus pandemic contributed to the increase in the homeless population and that unemployment was identified as the main cause. These people are looking for an alternative to obtain income and have become victims of urban and police violence and social discrimination.

Abstract. During the operation and dismantling of nuclear facilities, individual pipelines must always be removed due to leaks because of the end of their maximum service life or the dismantling of the plant. In practice, this activity, which at first glance appears simple, is associated with many challenges due to limited space or the fact that the pipelines run through walls, despite various solutions that are available on the market. Therefore, the aim of the joint research project “RoTre” (Development of a novel universally inside pipe separator for dismantling contaminated pipelines) between KIT, Siempelkamp NIS Ingenieurgesellschaft mbH and RWE Nuclear GmbH is the development of an innovative and competitive inside pipe separator for use in decommissioning and dismantling of nuclear facilities with a wide range of applications for various pipe diameters, wall strengths and materials (Fig. 1). An amendment will be the forward cleaning, whereby metal chips or other components can be captured continuously. Besides the dismantling in areas which are difficult to access, such as pipelines set in concrete or pipelines that cannot be drilled over their full length, dismantling should be possible in air and under water. After application, the system can be decontaminated. In order to separate pipes made out of different materials with various wall thicknesses, the development of a universally applicable test stand is planned in order to achieve the scientific work objectives. Among other things, it should be determined whether a sawing or an abrasive cutting process is more suitable for cutting inside pipes. Building on this, the parameters of the separation process are tested in a parameter study to achieve the smallest possible process forces with a universal applicability. Relevant parameters are the geometry parameters of the cutting unit like the saw tooth shape, the composition of the cutting wheel, as well as the process parameters in the form of infeed, cutting speed and tool speed. The cutting quality achieved by the different tools with the setting of the machine parameters is also an evaluation criterion for the selection of the cutting process.

Abstract The efficiencies observed in simul-frac operations are commonly associated with a singular, four-plus well pad containing an even number of wells. These efficiencies yield significant savings and reduction in overall completion time, expedite first-production and substantially reduce the time in which offset wells are shut in during frac operations. The introduction of remote simul-frac operations in the Delaware Basin, proven by Matador Resources Company in their Stateline asset, has removed this operational single-pad limitation by connecting adjacent multi-well pads and opening the opportunity to capitalize on ‘traditional’ simul-frac efficiencies on multiple pads simultaneously. Simul-frac is the use of a singular frac crew to simultaneously stimulate two separate wells. In most cases, the frac crew is equipped with an increase in hydraulic horsepower to be able to achieve rates ranging from 120 – 160 barrels per minute. The backside equipment in a Simul-Frac operation remains relatively unchanged, with the crew still utilizing only one blender. In earliest trials, wells completed via simul-frac operations were on the same pad and potentially receiving an uneven split of the fracturing slurry. By splitting the flow on the low- and high-pressure side of the frac, Matador and Universal Pressure Pumping were able to evenly meter the flow of slurry to two separate banks of pumps on location. One bank led to a zipper manifold on the same location that directed flow accordingly. The other bank directed flow along a 1,500′ high-pressure flanged-pipe frac line to an adjacent location to stimulate its "partner" well. Remote, satellite-communicating pressure gauges were used to monitor pressures on the adjacent pad. Matador has reported savings of up to ~7.5% of total completion spend per well and increased completed lateral footage per day by upwards of 50% on four well simul-fracs. Six of eleven batched wells in the Stateline asset were selected as a pilot location in Q4 of 2021 for remote simul-frac operations. Two three-well pads, Pad A and Pad B, were to be connected via high-pressure frac line and simultaneously stimulated. A Universal frac spread capable of 160 bpm was rigged up on Pad A and successfully stimulated wells on both Pad A and Pad B, via a high-pressure remote frac line throughout the job. The remote frac operations were a success; 6 wells, 407 stages, and over 73,000 lateral feet were completed in just under 33 days. In addition to the ~7.5% total completion spend per well savings, Matador was able to reduce total completion time by roughly 20 days, which brought forward production on the 11 well batch by 20 days and simultaneously reduced shut-in time of 16 offset wells. Successful remote simul-frac operations have enabled Matador to revisit a much wider variety of planned pads as candidates for simul-frac activity. After successful implementation in Q4 2021, Matador was able to increase its 2022 simul-frac activity by 91% due to remote operations.
