Purpose. To establish economic feasibility of growing walnut rootstocks. Methods. Walnut seedlings, promising as rootstocks in Ukraine, were studied in nurseries IE Zatokovyi V. Yu. (Sloboda Komarivtsi village, Storozhynets district, Chernivtsi region) during 2018–2020. Economic efficiency of growing rootstocks was determined according to the Method of economic and energy assessment of types of fruit and berry plantations, pomological varieties and the results of technological research in horticulture (2002). Results. To determine the economic efficiency of seedling cultivation, the technological map of walnut seedling cultivation was analyzed. The largest share in the structure of costs was accounted for by labor remuneration – 86.7%. The reason was the use of manual labor, which accounted for 96.5% of the total technology of growing seedlings. The level of mechanization of cultivation was only 3.5%. The total fuel consumption per 1 hectare was 120.7 liters, or UAH 2,957.20 in monetary terms. Thus, fuel consumption accounted for a small share – 0.4% of the cost of one seedling. One hectare of land provided an output of 65 thousand pcs of walnut seedlings, which amounted to 1,625 thousand UAH at a cost of 25 UAH/piece. Material costs amounted to 46.16 thousand UAH/ha (total costs – 712.43 thousand UAH). Therefore, the cost was extremely low and the level of profitability was extremely high.          Conclusions. Growing walnut seedlings of the varieties ‘Slava Ukrainy’, ‘Pamiati Zatokovoho’, ‘Lysychanskyi’ is economically feasible. This is due to the relatively low cost of one seedling (UAH 10.82) and high profitability of production of the original breeding material for grafting and planting industrial crops.

The scientific article presents the duration of acaricidal effect of «Kenem» drug, and its economic feasibility for protecting cattle against ixodic ticks. As a result of the study, the acaricidal efficacy and the duration of the residual acaricidal effect of drugs are important components in the planning of anti-tick measures. From a practical point of view, the economic feasibility of treating cattle against ixodic ticks in the presented conditions of acaricides in the southern regions is considered important. Despite the fact that the cost of the drug per 100 head exceeds the cost of a similar drug by 1 788.15 tenge, the frequency of its use is less, and additional installations are not required. This is due to the long duration of residual acaricidal effect of Kenem, which is 30 days, which allows to reduce the number of therapeutic measures.When calculating the economic feasibility for the use of acaricides to protect cattle against ixodic ticks, the most convenient way to prevent the sucking of ixodic ticks to animals is the local application of Kenem, which does not require special equipment and special skills of technical staff. Drug duration is 30 days, therefore the cost of its use for the entire season of active ticks per 1 animal is 44% cheaper, compared to veteran, i.e. 1,421.4 tenge.

In this work an Engine Management System (EMS) using a low cost 8-bit microcontroller specifically for the cost sensitive small two-wheeler application was designed and developed. Only the Throttle Position Sensor (TPS) and the cam position sensor (also used for speed measurement) were used. A small capacity 125CC four stroke two-wheeler was converted into a Port Fuel Injected (PFI) engine and was coupled to a fully instrumented Eddy Current Dynamometer. Air-fuel ratio was controlled using the open loop, lookup-table [speed (N) and throttle (α)] based technique. Spark Time was controlled using a proportional / fuzzy logic based close loop control algorithm for the idle speed control to reduce fuel consumption and emissions. Test results show a significant improvement in engine performance over the original carbureted engine, in terms of fuel consumption, emissions and idle speed fluctuations. The Proportional controller resulted in significantly lower speed fluctuations and HC / CO emissions than the fuzzy logic controller. Though the fuzzy logic controller resulted in low cycle by cycle variations than the original carbureted engine, it leads to significantly higher HC levels. The performance fuzzy logic can be improved by modifying the membership function shapes with more engine test data.

Syngas fermentation via the Wood-Ljungdahl (WL) pathway is a promising approach for converting gaseous pollutants (CO and CO2) into high-value commodities. Because the WL involves several enzymes with trace metal components, it requires an adequate supply of micronutrients in the fermentation medium for targeted bioprocessing such as bioethanol production. Plackett-Burman statistical analysis was performed to examine the most efficient trace elements (Ni, Mg, Ca, Mn, Co, Cu, B, W, Zn, Fe, and Mo) and their concentrations for Clostridium ljungdahlii on ethanol production. Overall, 1.5 to 2.5 fold improvement in ethanol production could be achieved with designed trace element concentrations. The effects of tungsten and copper on ethanol and biomass production were determined to be the most significant, respectively. The model developed was statistically significant and has the potential to significantly decrease the cost of trace element solutions by 18–22%. This research demonstrates the critical importance of optimizing the medium for syngas fermentation in terms of product distribution and economic feasibility.

Energy efficiency in South African industry has only recently started receiving attention due to the low cost of South Africa’s electricity, and a not too distant history of isolation leading up to democratic elections in 1994.This study shows that strong incentives exist for energy efficiency improvement in South African industry, in particular, the potential for increasing profit, the need to reduce greenhouse gas (GHG) emissions, the need to maintain economic competitiveness, and the need to delay the cost of new peak-load electricity generation facilities. Barriers to the implementation of energy efficiency projects need to be anticipated and addressed by managers, policy makers and energy efficiency practitioners. In particular, the lesson from the case study in this paper showed how organisation structure, financial controls and culture, can be barriers to the implementation of energy projects. By ensuring the support of top management, and by the initiation of an energy management program early on, these barriers can be avoided and results and recommendations from an energy assessment can feed into a receptive management system.

A low cost and reliable protection scheme has been designed for a three phase induction motor against unbalance voltages, under voltage, over voltage, short circuit and overheating protection. Taking the cost factor into consideration the design has been proposed using microcontroller Atmega32, MOSFETs, relays, small CTs and PTs. However the sensitivity of the protection scheme has been not compromised. The design has been tested online in the laboratory for small motors and the same can be implemented for larger motors by replacing the i-v converters and relays of suitable ratings.

Abstract Advanced jet training still relies on old concepts and solutions that are no longer efficient when considering the current and forthcoming changes in air combat. The cost of those old solutions to develop and maintain combat pilot skills are important, adding even more constraints to the training limitations. The requirement of having a trainer aircraft able to perform also light combat aircraft operational mission is adding unnecessary complexity and cost without any real operational advantages to air combat mission training. Thanks to emerging technologies, the JANUS project will study the feasibility of a brand-new concept of agile manoeuvrable training aircraft and an integrated training system, able to provide a live, virtual and constructive environment. The JANUS concept is based on a lightweight, low-cost, high energy aircraft associated to a ground based Integrated Training System providing simulated and emulated signals, simulated and real opponents, combined with real-time feedback on pilot’s physiological characteristics: traditionally embedded sensors are replaced with emulated signals, simulated opponents are proposed to the pilot, enabling out of sight engagement. JANUS is also providing new cost effective and more realistic solutions for “Red air aircraft” missions, organised in so-called “Aggressor Squadrons”.
