Functional fragmentation remains a critical constraint in information-intensive organizations, limiting workflow coherence and reducing overall process performance. This study provides an empirical analysis of workflow–structure alignment, with particular emphasis on coordination and governance mechanisms as means of integrating fragmented functional activities. Drawing on Business Process Management (BPM) and socio-technical systems theory, alignment is conceptualized as the integration of organizational struct...

This paper analyses a multi-apartment residential building undergoing staged renovation during the heating season using real-time, hourly metered heat consumption data over two consecutive winters in a temperate-cold climate. The renovation is implemented in clearly identifiable phases, which enables an empirical, measure-by-measure assessment of changes in heating demand as works progress. The analysed interventions include insulation of basement heat distribution pipework, attic insulation, external wall insulat...

This paper analyses how designing the same single-family building to different energy performance standards affects its life-cycle costs. The study compares five design scenarios for one building, starting from the current national minimum energy performance requirement, moving through a typical nearly zero-energy building solution and an enhanced NZEB variant, and progressing towards a highly energy-efficient Passive House and a Passive House PLUS solution with on-site photovoltaic generation. Each scenario is ev...

In this paper is presented a Mobile Integrated System for on the Site Testing (MISST) of equipment intended for use in potentially explosive atmospheres, with type of protection pressurization p, resulting from research activities out by the research and testing team involved. The fundamental aspects of the design, implementation and easy use of such an integrated system have been examined, implemented and tested. A mobile integrated test system for Ex p type of protection applied to equipment in Ex construction, ...

This study examines how organizational structure and workflow/process design can be aligned in information-intensive organizations through Business Process Management, workflow standardization, digital automation, and adaptive governance. The study develops and evaluates the Adaptive Workflow–Structure Integration Model, which integrates structural standardization, digitally orchestrated workflows, and governance mechanisms into a unified socio-technical framework. The model is applied in a document-intensive or...

The general concern about climate change and the actions that must be taken to protect the environment are current concerns and occupy the first places on global agenda regarding the search for viable and sustainable solutions. Transition to green energy involves numerous intensely analysed issues with major implications for the economies of many countries. Thus, integration of renewable energy in oil and gas operations is an increasingly used strategy to reduce the carbon footprint and improve sustainability of t...

Accurate estimation of soil organic carbon (SOC) is critical for carbon accounting in high-altitude ecosystems, where variability in soil properties challenges the use of standardized conversion factors. This study assesses the validity of the Van Bemmelen conversion factor (1.724) for estimating SOC from soil organic matter (SOM) across contrasting Andean ecosystems within the upper Pastaza River watershed in Ecuador, with a primary focus on paramo. A total of 109 soil samples were collected at 30 cm depth using ...

The need to develop an integrated testing system for explosion-protected construction equipment with the type of protection "p" arose from practical considerations. The use of a mobile, versatile and adaptable system for the field performance of tests specific to this type of protection applied to explosion-protected construction equipment brings several novel advantages, the most important of which are: grouping all the test equipment required for the tests, elimination of measurement errors by performing several...

The Growing concern about climate change and the actions that need to be taken to protect environment have begun to occupy the top places on global agenda in recent years. Transport of the future will look different: ecological, economic and maximum efficiency. But it's not only car manufacturers who are making efforts to reduce as much as possible the climate impact of vehicles. One of solutions is and the major interest of using hydrogen as a viable answer for decarbonizing industrial processes and economic sect...

An ambitious reduction in greenhouse gas emissions is set by the political initiative -The European Green Deal- and -Fit for 55- package. The municipalities, which carry out the strategic management of the district heating systems, will have to ensure the sustainable development of the territory in a way that includes a significant increase in energy efficiency both in the building stock and in the related district heating system. The aim of this research is to study and develop an easy-to-use methodology and an a...

The use, production, processing and storage of petroleum products and gases generate hazardous atmospheres that can be ignited and generate explosions, causing serious damage both to materials and the environment, and especially to human health and integrity. The use of equipment in this environment requires compliance with certain well-defined parameters, which must be chosen in correlation with the potentially explosive atmosphere in which it is to be installed and the type of protection, temperature class and c...

Frequency of storms and wind speeds in gusts had been increasing in Northern Europe in last decades, causing more damages to forest stands. Establishment of mixed stands had been suggested as one of the methods to reduce wind damages in future, however, empirical information on actual efficiency of this approach is still limited, especially in relation to summer storms. Therefore aim of our study was to assess summer storm damages in mixed birch spruce stands. Area influenced by the storm of June 2021 in Northern ...

The purpose of this study is a spatial-dynamic and structural hygienic assessment of the impact of the activities of thermal power facilities on the quality of atmospheric air and the formation of potential risks of harm to the health of the population in a large industrial center with a population of more than 350 thousand people and a total area of more than 500 square kilometers. At present, heat and power facilities belong to the main industries and form significant potential risks of harm to public health in ...

This study performed a hygienic analysis of pollutant emissions from stationary and mobile sources and hygienic assessment of air quality for 2007-2019 according to official statistics of the Russian Federation. It was found that the main sources of emissions are motor vehicles, ferrous and nonferrous metallurgy, fuel and energy complex, machine building, timber, woodworking, coal, mining, pulp and paper, chemical and oil refining industries. As results of hygienic analysis showed, the total amount of pollutant em...

The present work dwells on testing methodical approaches to optimization of programs for monitoring over ambient air quality. The key issue here was to determine how many control points are required and make up a list of substances for monitoring in a large industrial center with its area exceeding 350 square kilometers and population more than 1 million people. Ambient air quality in the examined city is influenced by more than 150 industrial enterprises operating in metallurgy, civil engineering, chemical indust...

The calculated energy efficiency and specified physical properties of building materials may change significantly during the initial years of a buildingпїЅs operation under real climatic conditions. Five small test buildings with different wall assemblies were built in Riga, Latvia to compare different building construction characteristics under Latvian climate conditions. The heating energy consumption, thermal transmittance, air relative humidity and other important energy efficiency and environmental parameters...
