Selected defects of one-way clutches based on Mi-24 helicopter – reasons, effects and diagnosing
Authors: Tokarski Tomasz , Obłąkowski Krzysztof , Parucki Janusz , Kucharzewski Tomasz , Kwiatkowski Tadeusz 
Published: April 2022

Abstract
This manuscript describes the proprietary method of diagnosing one-way clutches of Mi-24 at their earlier wearing stage, which is challenging to diagnose with traditional methods (vibroacoustic). The FAM-C method is based on the analysis of frequency modulation of the on-board generator driven from the examined power unit. It enables to observe the influence of other mechanical elements on the operation of this clutch: it monitors all rotary subassemblies of aircraft connected with mechanical power transmission. The manuscript aims to review the typical defects of one-way clutches in helicopter propulsion systems, describe the FAM-C method as a basic method at the early diagnosing stage and confirm its efficiency based on the provided results.
An Attempt to Characterise the Reliability of an Action Considering the Type of Its Result
Authors: Smolnik Maksymilian 
Published: April 2022

Abstract
The paper presents the results of research related to one of the problems identified in the previous work, which included the analysis of selected elements of the concept of reliability of action description in the systems of action engineering developed by Józef Konieczny. The aim of this study is to analyse the possibility of using the praxiological classification of results in a partially formalised description of the reliability of action. In the first stage of considerations, observations were made regarding the description of the reliability of actions presented as isolated simple chains of action. In the second stage, the observations related to the description of the reliability of actions under the conditions of direct supporting were made.
Determinations and Interpretations of Heavy Metal Analysis in the Sediments and Water of Cavnic and Lăpuş Rivers
Authors: Bud Adina 
Published: April 2022

Abstract
The article presents laboratory analysis of the water and sediment samples taken on September 2021 from Cavnic and Lăpuș rivers. The values of these results are interpreted by reference to the Technical Regulations on heavy metal contents in discharged waters into the emissary, without being able to be reported on regulations on river sediments. An analysis is made of the impact of these contents leading to complete destruction of aquatic life in the areas of sampling.
Further results on strictly Lipschitz summing operators
Authors: Belaala Maatougui , Saadi Khalil 
Published: April 2022

Abstract
The aim of this paper is to give some new characterizations of strictly Lipschitz p-summing operators. These operators have been introduced in order to improve the Lipschitz p-summing operators. Therefore, we adapt this definition for constructing other classes of Lipschitz mappings which are called strictly Lipschitz p-nuclear and strictly Lipschitz (p, r, s)-summing operators. Some interesting properties and factorization results are obtained for these new classes.

The Use of Statistical Methods in Croatian Enterprises During the Early Stages of COVID-19
Authors: Žmuk Berislav 
Published: April 2022

Abstract
The appropriate application of statistical methods in enterprises should have an important role in business decision-making processes. However, Croatian enterprises still tend to have certain resistance to statistical methods. The new challenges introduced by the COVID-19 pandemic emphasised the importance of conducting statistical analyses as support for making business decisions. In order to investigate the situation and attitudes towards the use of statistical methods, primary research was conducted in the form of a web survey on a sample of 768 Croatian enterprises, of which 40% use statistical methods in their business. The research revealed the level of statistical methods use in Croatian enterprises, demonstrated which statistical methods Croatian enterprises prefer, and defined who is most responsible for their use. Furthermore, the reasons for the use of statistical methods and the major obstacles to the use of more intensive statistical methods were also investigated. The results are described and discussed on an overall level and by considering the size of the enterprises.
Charging and Discharging Strategies for Clustered Regional Energy Storage System
Authors: Li Yang , Janik Przemysław , Pfeiffer Klaus , Schwarz Harald 
Published: April 2022

Abstract
With the massive expansion of decentralised renewable energy in electricity grid networks, the power supply system has been changed from centralised to decentralised one and from directional to bi-directional one. However, due to the regional energy structure difference in the power imbalance between electricity generation and consumption is becoming more and more serious. A grid-scale energy storage system (ESS) can be one solution to balance the local difference. In this paper, two charging/discharging strategies for the grid-scale ESS were proposed to decide when and with how much power to charge/discharge the ESS. In order to realise the two strategies, this paper focuses on the application of fuzzy logic control system. The proposed strategies aim to reduce the peak power generation, consumption and the grid fluctuation. In particular, this paper analysis the ratio between energy-capacity and rated power of ESS. The performance of the proposed strategies is evaluated from two aspects, the normalised power of ESS itself and the influence on the power grid. Simulation studies were carried out on the rule-based control systems with different energy-to-power (e2p) ratios, and the results show that the proposed charging strategy with combination of extreme situation of power imbalance and the rest capacity of ESS provides a smooth load curve for the regional power grid system while the external power exchange is reduced effectively.

Published: April 2022

Abstract
The paper presents the study of the influence of different ferromagnetic powders on magnetic properties of polymer-matrix soft magnetic composites. Samples were prepared from pure Fe and Permalloy powders with the same amount of resin and by the same technological process. The coercivity, the real part of complex permeability, saturation magnetic polarization, hysteresis loops and total energy losses and their components were investigated. It was found that the coercivity, DC losses, classical losses, excess losses and thus the total energy losses of composites depended on intrinsic magnetic properties and/or on the size and shape of ferromagnetic powder particles, while the permeability of composites was affected predominantly by inner demagnetizing fields due to the insulation. The numbers of moving domain walls involved in magnetization reversal were analyzed in connection with the magnetic properties.

Authors: Kyryliuk Yevheniia , Bagliuk Gennadii , Mamonova Alla , Maslyuk Vitaliy 
Published: April 2022

Abstract
The results of the investigation of the structure, phase composition, and properties of the alloy sintered from a mixture of iron (65 %) and high-carbon ferrochrome (35 %) powders are presented in the article. It was shown that sintering of the consolidated specimens results in a substantially heterogeneous structure consisting of two predominant phases: austenitic phase and double ferrochrome carbide. A mechanism is proposed for the dissolution of ferrochrome particles in the iron matrix as follows: M7C3 → M3C (1000÷1150 ºС) → M7C3 (1200÷1250 ºС).

Authors: Snoj Ziga , Tomazin Tjasa , Salapura Vladka , Kuhelj Dimitrij 
Published: April 2022

Abstract

Background
Endovascular abdominal aortic aneurysm repair (EVAR) has become a mainstay of abdominal aorta aneurysm treatment. Long term follow-up on specific stent grafts is needed.

Patients and methods
This study included 123 patients (104 men; mean age 73.0 years, range 51–89) with abdominal aorta aneurysm, treated with Excluder® stent graft between October 2002 and June 2008. Periprocedural and follow-up data were retrieved by reviewing the records of our institution, while time and cause of death were retrieved from the National Institute of Public Health. If an abdominal aortic aneurysm rupture was listed as the cause of death, records were retrieved from the institution that issued the death certificate. Our primary goal was to assess the primary technical success rate, type 1 and type 2 endoleak, reintervention free survival, 30-day mortality, the overall survival and aneurysm rupture-free survival.

Results
The median follow-up was 9.7 years (interquartile range, 4.6–13.8). The primary technical success was 98.4% and the 30-day mortality accounted for 0.8%. Secondary procedures were performed in 29 (23.6%) patients during the follow-up period. The one-, five-, ten-, fifteen- and seventeen-year overall survival accounted for 94.3%, 74.0%, 47.2%, 35.8% and 35.8%, while the aneurysm-related survival was 98.4%, 96.3%, 92.6%, 92.6%, 92.6%. In seven (5.7%) patients, abdominal aortic rupture was found as the primary cause of death during follow-up.

Conclusions
Our data showed that EVAR with Excluder® stent graft offers good long-term results. More than 75% of patients can be treated completely percutaneously. Late ruptures do occur in the first ten years, raising awareness about regular medical controls.
Image reconstruction using small-voxel size improves small lesion detection for positron emission tomography
Authors: Rep Sebastijan , Tomse Petra , Jensterle Luka , Jarabek Leon , Zaletel Katja , Lezaic Luka 
Published: April 2022

Abstract

Background
PET/CT imaging is widely used in oncology and provides both metabolic and anatomic information. Because of the relatively poor spatial resolution of PET, the detection of small lesions is limited. The low spatial resolution introduces the partial-volume effect (PVE) which negatively affects images both qualitatively and quantitatively. The aim of the study was to investigate the effect of small-voxel (2 mm in-line pixel size)
vs.
standard-voxel (4 mm in-line pixel size) reconstruction on lesion detection and image quality in a range of activity ratios.

Materials and methods
The National Electrical Manufacturers Association (NEMA) body phantom and the Micro Hollow-Sphere phantom spheres were filled with a solution of [18F]fluorodeoxyglucose ([18F]FDG) in sphere-to-background ratios of 2:1, 3:1, 4:1 and 8:1. In all images reconstructed with 2 mm and 4 mm in-line pixel size the visual lesion delineation, contrast recovery coefficient (CRC) and contrast-to-noise ratio (CNR) were evaluated.

Results
For smaller (≤ 13 mm) phantom spheres, significantly higher CRC and CNR using small-voxel reconstructions were found, also improving visual lesion delineation. CRC did not differ significantly for larger (≥ 17 mm) spheres using 2 mm and 4 mm in-line pixel size, but CNR was significantly lower; however, lower CNR did not affect visual lesion delineation.

Conclusions
Small-voxel reconstruction consistently improves precise small lesion delineation, lesion contrast and image quality.

ABSTRACT
The activities of the palm oil industry produce waste in the form of empty fruit bunches of oil palm. The empty fruit bunches of this oil palm act as a medium for growing oil palm mushrooms. The extent of oil palm plantations in Sangir Balai Janggo District has the potential to produce large quantities of oil palm mushrooms. The problem that exists is that until now, the interest of the people of Sangir Balai Janggo District in utilizing the potential that exists in their area is still very low, because there is still very lack of information about the utilization and processing of this palm mushroom. Whereas this palm mushroom is very possible to be used as healthy food because it has a high protein content and low fat content. In addition, another problem is that this palm mushroom is a food ingredient with the characteristics of rapidly decaying after being harvested, if it is not immediately handled and processed further it will reduce the quality of the aroma, shape, and taste of the palm mushroom. Therefore, to maintain the quality of the palm fungus, it is necessary to carry out further handling and processing so that it can maintain the quality of the palm fungus.
