Increasing the quantity and quality of potatoes by utilizing seed size and fish organic fertilizer

Potato plants are one of the vegetables that are in great demand by consumers so they have high economic value and needs. The fulfillment of high needs must be accompanied by increased productivity. Increased potato production can be done, among others, by the use of seeds and proper fertilization. This study aims to determine the use of seed size and addition of fish organic fertilizer with inorganic fertilizer efficiency in increasing potato growth and yield. The study is carried out from June until September 2019 in research and assessment installation of agricultural technology, Dolat Rayat District, Karo Regency. The research placed altitude is ± 1,340 m above sea level, and the soil type is Andisol. The research design is a factorial randomized block and consists of three replications. The first-factor treatment is seed size (big >20 g, medium 5-20 g, small <5 g). The second factor is a fish organic fertilizer with efficiency inorganic fertilizer (100% inorganic fertilizer, 50% fish organic fertilizer + 75% inorganic fertilizer, 100% fish organic fertilizer + 50% inorganic fertilizer, and 150% fish organic fertilizer + 25% inorganic fertilizer). The result showed that big and medium seed sizes were able to increase potato growth and yield. Big and medium seed sizes were able to increase plant height by 11.06% and 9.63%, 5,73%, and 4,64% canopy width, 7.30%, and 11.10% leaf area index, and 12.62% and 25.06% yields from small seed size. Adding fish fertilizer with inorganic fertilizer efficiency resulted in growth and yield which is no different from the application of 100% inorganic fertilizer.

Design for Time-to-Market – Why Timing is Essential for a Successful Green Hydrogen Economy

Within the last years but especially since the beginning of 2022 there is a large increase in the demand of renewable energy. Currently, so-called green hydrogen is one of the most promising energy carriers for renewable energy. To meet the demand for green hydrogen, installation of production technologies like water electrolyzer is necessary. In order to play a role within the hydrogen economy, companies have to be able to design their hydrogen production capacities for a spot-on time-to-market. This leads to difficult ramp-up decisions and trade-offs between costs, technological maturity, and market success. As the phases of research and development influences a significant part of the costs (especially within production) after reaching time-to-market, they determine the later cost structure of the company, the possibilities to gain a competitive advantage or to survive on the market. Analyzing literature with regard to wind and photovoltaic industry shows several factors influencing success. This paper identifies and discusses these critical success factors, transfers their relevance onto the current hydrogen economy, and points out critical aspects for market entry decisions. With respect to a globalized world, in which dependencies from single countries can lead to unwanted constraints, the results become even more important.

Increasing energy efficiency in Smart Building through Internet of Things retrofitting intervention

Buildings are responsible for 40% of energy consumption in Europe, and 75% of them are energy inefficient. In this context, the opportunities enabled by improved management and conservation of energy in buildings are huge. There is a clear need to accelerate and finance building renovation investments and leverage smart, energy-efficient technologies if the EU wants to reach climate neutrality by 2050. IoT components enable new possibilities for improving efficiency in Smart Buildings, both in commercial and residential spaces. However, the literature misses some contributions aimed at evaluating the investment in IoT technologies used for improving the energy efficiency of a building used for different purposes. Thus, the objective of the present study is to provide an assessment of the main costs and benefits stemming from IoT technologies installation through retrofitting intervention and evaluate the sustainability of the investment. Data to feed the model were retrieved from academic literature and secondary sources. The results show that the investment can be recovered in the medium-short term. In particular, buildings with high consumption rates are the ones that benefit the most from this solution. The present study contributes to the academic literature by providing a model that considers a mixed building and multiple technologies at the same time. It also provides useful insights to whoever is interested in the application of IoT technologies to make a building smart, enabling the comprehension of necessary investment and economic returns.

Технология получения топливного газа для нефтеперерабатывающей промышленности

Reducing energy costs for production and reducing air pollution is one of the key tasks today. The main sources of atmospheric air pollution at oil refineries are: tubular heating furnaces - 50%; reactors of technological installations - 12%; flares - 29% and bitumen installations - 9%. Therefore, the development and implementation of methods to reduce harmful emissions and increase energy efficiency during fuel combustion is one of the main environmental objectives. In the process of oil refining, a large number of gas components of different potentials, pressures and homogeneity of the medium are formed. The forming gases are usually sent to the torch as a recyclable product, and the lack of energy resources is compensated by the use of liquid fuel or natural gas. Consequently, the task of better consumption of hydrocarbon gas is being formed with the possibility of reducing the consumption of liquid fuel and natural gas, i.e. increasing the energy efficiency of production, which leads to a reduction in harmful emissions into the atmosphere. To achieve these goals in the oil refining industry, on the example of LUKOIL-Volgogradneftepererabotka LLC, a plant for producing composite fuel gas for oil refining furnaces was developed and a new composite fuel gas based on hydrogen-containing and hydrocarbon gases of its own production was obtained. The composition of the composite fuel gas includes a "blow-off" hydrogen-containing gas, previously burned on a flare.

Environmentally friendly material for the construction of pile foundations on permafrost

Modern construction of pile foundations in permafrost conditions includes a cycle of operations: conducting geological and geodesic surveys; developing design and estimate documentation; construction and installation work; monitoring. Six main indicators are considered to determine the organizational and technological reliability of pile foundations for industrial tanks in permafrost soils: environmental performance (EF), intensity (Cf), cost (Cf), innovation (Mf), operational reliability (ORf), quality (Qf). Eco-friendliness depends on the material, the immersion technology, embedding depth, engineering and environmental survey, and other factors. Quality depends on determining the characteristics of the soil, assessing the depth of the hard frozen ground, methods for analyzing the strength characteristics of piles, pile inspection methods, materials, sinking technology, and other factors. The intensity depends on the volume and duration of the work. The duration depends on the depth of the foundation, pile installation technology, climatic conditions, soil characteristics, and other factors. The cost depends on the depth of embedding, immersion technology, material, construction area, the complexity of the project, and other factors. Innovativeness depends on introducing new technologies, resistance to climate change, material, structural changes in piles, and other factors. Operational reliability depends on permafrost soil characteristics, foundation design parameters, material performance characteristics, process parameters, operating conditions, inspection and maintenance, and other factors.

Проблема оптимізації лабораторного ущільнення асфальтобетонних сумішей

The problem of ensuring the durability and operation of asphalt concrete layers of non-rigid road surfaces is closely related to the quality of the materials used, their composition and installation technology. The latter includes two defining stages: moving mixtures and their compaction. At the same time, the prediction of the properties of asphalt concrete should be carried out based on the results of laboratory tests, in the process of which the road, climatic and transport conditions of operation of one or another layer are taken into account. Reliable prediction can be ensured if the conditions of laboratory research and production processes are identical. This mostly applies to the laboratory seal, which must match the production seal. The existing state of affairs does not meet this condition. For many decades, laboratory compaction was carried out by pressing asphalt concrete mixtures under a pressure of 20 MPa with vibration up to 40 MPa. Western European researchers and builders have been aware of this problem for more than 50 years. Due to this, fundamentally new methods of laboratory compaction appeared in the world (impact and vibration-impact type, rolling with metal and pneumatic rollers, displacement with pressure in the case of rotary presses). In Ukrainian practice, such methods are practically not used, despite the fact that the first rolling press was developed in KADI. The results of comparative studies of asphalt concrete compacted by the following methods: pressing, sector rolling, and rotary compaction are presented. Attention to the advantages and disadvantages of each of them is accepted. Keywords: asphalt concrete mixture, compaction by pressing, rolling, rotary shear, kinetics of gradual compaction, bitumen content.

SKILLS OF WORKING WITH PHOTO AND VIDEO MATERIALS AS A COMPONENT OF TEACHER'S ICT COMPETENCE IN DISTANCE LEARNING

The article deals with the urgent problem of increasing the level of teacher's information, communication and technological competence in the conditions of the use of all levels of distance learning technologies in educational institutions. The article considers the essence of the concept of teacher's ICT competence and establishes that its necessary component is the ability to present educational material, using the necessary ICT tools for this.
 The results of a survey of teachers of the Ukrainian language and literature, as well as physics, astronomy and computer science, conducted during the postgraduate training courses for teachers organized at Zhytomyr Ivan Franko State University during September-December 2021, are presented. As a result of the survey, it was found out which teaching materials have been used by the teachers in the process of distance learning, and what with difficulties they meet during the lessons in a distance format. It was found that the majority of teachers have used ready-made presentations, illustrative and video materials taken from the Internet, and the greatest difficulties for them were the creation of their own photo or video materials and multimedia presentations.
 It is proposed to hold thematic classes with teachers during their postgraduate training courses. The content of the classes is given, namely: the peculiarities of working with Internet catalogs of photo and video files; the review of the most popular online services for creating infographics, editing raster and vector images; the technology of preparation and installation of video materials; the artistic approach to building the composition of the frame and the psychology of its perception by the viewer.
 Thus, the implementation of the proposed approaches in the practice of the institutions that carry out postgraduate education of teachers will contribute to the development of ICT competence in the teachers, which will positively affect the quality of conducting educational and extracurricular activities in the conditions of distance learning. The perspective of further research is to study the possibilities of increasing the level of ICT competence in the teachers by using online learning management systems.

Assessing the impact of the process of constructing foundation pit enclosure structures on surrounding building

An important issue in the calculations of retaining structures of pits and their interaction with the foundation and existing structures is taking into account the features of their installation technology. Quite often, during calculations, this factor is ignored or taken into account by introducing correction factors, which are somehow based on the statistical processing of observation data during the construction of similar objects.
 The development of numerical methods has enabled designers to use detailed finite-element models in calculations to more accurately predict the behavior of bases and structures, without spending excessive amounts of time.
 In this work, numerical modeling methods are used to reproduce the process of installation of the pit enclosure structures using the trench method "wall in soil" to determine its impact on existing buildings. For this, a numerical model of a 9-floor building with a soil massif was created. Modeling of the foundation pit and enclosure structures, which is installed next to the building, was done. At the same time, the use of a three-dimensional formulation of the problem made it possible to take into account the length of the wall panel and the technological sequence of the construction.
 The existing methods of trench excavation modeling were analyzed and one of them was implemented in the calculation scheme.
 The impact of various factors on the formation of additional deformations of the existing building was investigated, such as: L - distance from the foundation pit to the building; Нст - the depth of laying the sole "wall in the ground"; Lзхв - the length of the wall panel; ρг.р - is the density of the clay slurry.
 Within each task, the settlement of the foundation of the building is determined with different input parameters: L={1,2; 3; 5; 10m}, Нст={12; 18; 24m}, Lзхв={3; 4; 5m}, ρг.р={1.05; 1.10; 1.30t/m3}. The results are presented in the form of graphs.
 The results of the research show that the most determining factors affecting the «technological settlements» of the slab foundation of the building are the distance from the pit to the building and the depth of laying the sole of the "wall in the soil". With different combinations of these parameters, the values of calculated vertical deformations of the building can differ up to several times.

Use of a novel water separation process for the recovery of the mineral fraction from the stabilized organic fraction found in municipal waste.

Currently, the Stabilized Organic Fraction (SOF) 0-80 mm separated from the municipal waste stream is sent in its entirety to landfill in the mechanical-biological treatment plants operating in Poland. Such action does not align with the adopted EU strategy focused on waste management in the circular economy. This study aimed to assess the technical feasibility of the process of purification of mineral fractions with a grain size of 10-80 mm separated from SOF on a technological installation designed for glass recovery, built at the Marszów Plant. In terms of material, mineral fractions are a mixture of stones, rubble and glass, contaminated with various components, mainly organic. In 2020, the glass recovery installation was expanded with an innovative process of gravity separation to separate mineral fraction from SOF with the use of a jigging machine. A pulse jig used in the mining industry for coal enrichment processes was used for the first time in municipal waste management. The installation allows for the recovery of between 71.1 and 96.6% of mineral fractions contained in the input (84.8 ± 9.5% on average). The proportion of organics, plastics and other impurities in the waste is 4.1 ± 2.1% of the fraction mass. The process consumed water at an average rate of 0.34 ± 0.10 m3 tonnes-1 of treated waste and generated 0.26 ± 0.09 m3 tonnes-1 of wastewater. Electricity consumption averaged 1.20 kWh tonne-1 input.

Multi-criteria optimization of the system for complex processing of oil contaminated waste regarding a set of system quality criteria

The paper proposes a new approach to solving the multicriteria optimization problem for the system for processing man-made waste of the oil and gas complex. The optimization problem is formulated as an integer mathematical programming problem with constraints. The objective function in the optimization problem is formed using a set of efficiency assessments obtained as a result of a multivariate analysis of resource and energy savings in the system for processing industrial waste from oil and gas enterprises based on the Data Envelopment Analysis (DEA) method. As restrictions in the problem, constraints on the maximum duration of the process of processing waste placed in a given group of storage facilities with the help of specialized technological installations are considered. Problem-oriented software has been developed for the numerical solution of the problem of multiobjective optimization.
