Publication Name: Mentalhigiene Es Pszichoszomatika
Publication Date: 2022-12-13
Volume: 23
Issue: 4
Page Range: 433-463
Description:
Theoretical background: There are several measuring instruments in the international literature for measuring spirituality. One of the most widely used and reliable self-reported questionnaires is the Spiritual Health and Life-Orientation Measure (SHALOM). The questionnaire captures spiritual well-being holistically and is therefore well-suited to both religious and non-religious individuals. Aims: The primary objective of our study is to adapt SHALOM to Hungarian and to perform detailed psychometric analysis, including testing factor structure, reliability, and validity. Methods: The questionnaire package used for validation (SHALOM, WBI-5 / WHO Well-Being Questionnaire /, SWLS / Life Satisfaction Scale /) was completed by a total of 437 university students (male: 24.2%, female: 75.8%, mean age = 21.6 years; SD = 1.8 years). Results: Exploratory and confirmatory factor analyzes on the items of the SHALOM questionnaire confirmed the bifactor structure (4 primary and 1 general factors), supporting the theoretical factor structure of the instrument. The primary factors are: Personal, Social, Environmental, and Transcendent Scales for both aspectsof evaluation (ideal and experienced). However, there were 6 items that did not fit perfectly into the four primary factors: 4 items for ideal assessment and 2 items for experienced. In the ideal assessment, the items in the questionnaire explain 66.6% of the total variance and 64.9% in the case of experienced. Factor structures gave acceptable fit indicators for both evaluation aspects (CFIideal = 0.99 and CFIexperienced = 0.97; and RMSEAideal = 0.057 and RMSEAexperienced = 0.068). The Cronbach-α value ranges from 0.69 to 0.97, indicating an overall acceptable internal consistency and the stability in time of the questionnaire is also adequate. According to our validity study, the scales for the two evaluations of SHALOM are significantly positively correlated with the WHO Well- Being Index and the Satisfaction with Life Scale (with the exception of the Personal scale for ideal evaluation), with correlations ranging from weak to moderate. Conclusions: Our results support the bifactor structure of the SHALOM questionnaire, confirm the internal consistency of the scales, and support the validity of the Hungarian version of the measurement tool. However, further studies in the field of construct validity testing are warranted in the future.

Publication Name: Agrokemia Es Talajtan
Publication Date: 2022-12-05
Volume: 71
Issue: 2
Page Range: 289-308
Description:
A review of the international literature also found that the amount and the presence in slurry of oestrus inducer hormone preparations used in intensive dairy cattle production has not been investigated. In our study, we followed the path of 5 different sex-inducing drugs (alfaglandin, PGF, dinolytic, gonavet, ovarelin) including three active pharmaceutical ingredients (D-Phe6-Gonadorelin, Kloprostenol and Dinoprost-tromethamine) used in a cattle farm in Pest County from their use until their appearance in the slurry from 2017 to 2020. The study included a review of drug consumption and a seasonal analysis of the hormonal effects of slurry produced on the farm in quarterly cycles each year. We also tested separately the hormonal effects of the hormone preparations used on the farm. For the estrogenic effect tests, the yeast test with the human estrogenic receptor was used according to ISO 19040. Statistical evaluation of the results (Pearson correlation and Principal Component Analysis) was used to identify relationships between the use of sex inducers, the reproductive biology of the colony and the estrogenic effect of the slurry. We found that the estrogenic effects of slurry and sludge are strongly correlated. All three pharmaceuticals tested showed a strong correlation with the estrogenic effect of slurry/sludge. Our investigations confirm that slurry among other reasons due to its hormone and drug content shall be considered as a material that needs to be disposed of by new treatment methods before application to the field, because of its environmental and health risks.

The effect of complex bacterial treatment of slurry on content and ecotoxicological properties
Publication Name: Agrokemia Es Talajtan
Publication Date: 2022-12-05
Volume: 71
Issue: 2
Page Range: 309-327
Description:
The subject of our research is the comparative ecotoxicological examination of the bacterial slurry treatment system distributed by NCH Magyarorszag Kft. The experiment was carried out on a cattle calf rearing farm, in the 0-6 months age group section. The bacterial strains available in tablet form were multiplied in a container and added weekly to the slurry collected in the shaft. The purpose of bacteria treatment was to promote homogenization of the manure, reduce odors, and break down organic impurities. The ecotoxicological tests were carried out before, during and after the manure treatment at three sampling times. As a result of our research, it has been revealed that during the slurry treatment, the internal content values increased significantly, mostly the nitrogen forms, the biological oxygen demand and the dry matter content. The presence of the estrogenic effect remained considerable even at the end of the treatment. Based on the phytotoxicity test, the fertilizer treatment had a positive effect on the stem and root growth of each plant. The results of the soil toxicity test proved that untreated slurry loses its inhibitory effect on the vital activity of sensitive bacteria at higher dilutions. The common duckweed test revealed that above 150 dilution, the inhibitory effect of the slurry ceases in the samples at all three sampling times. In order to inhibit the growth of algae, the liquid fertilizer showed a stagnant-inhibiting tendency during the treatment. Based on our results, we came to the conclusion that the bacterial slurry treatment system was effective in terms of homogeneity, deodorization and decomposition of organic matter. However, it is recommended to apply it to the fields at a higher dilution rate or with a high soil water content. Further studies are needed regarding the removal of substances with hormonal effects, based on which recommendations can be developed for farmers.

Challenges of sustainable agricultural development with special regard to Internet of Things: Survey
Publication Name: Progress in Agricultural Engineering Sciences
Publication Date: 2022-12-02
Volume: 18
Issue: 1
Page Range: 95-114
Description:
If we want to increase the efficiency of precision technologies to create sustainable agriculture, we need to put developments and their application on a new footing; moreover, a general paradigm shift is needed. There is a need to rethink close-At-hand and far-off innovation concepts to further develop precision agriculture, from both an agricultural, landscape, and natural ecosystem sustainability perspective. With this, unnecessary or misdirected developments and innovation chains can be largely avoided. The efficiency of the agrotechnology and the accuracy of yield prediction can be ensured by continuously re-planning during the growing season according to changing conditions (e.g., meteorological) and growing dataset. The aim of the paper is to develop a comprehensive, thought-provoking picture of the potential application of new technologies that can be used in agriculture, primarily in precision technology-based arable field crop production, which emphasizes the importance of continuous analysis and optimisation between the production unit and its environment. It should also be noted that the new system contributes to reconciling agricultural productivity and environmental integrity. The study also presents research results that in many respects bring fundamental changes in technical and technological development in field production. The authors believe that treating the subsystems of agriculture, landscape, and natural ecosystem (ALNE) as an integrated unit will create a new academic interdisciplinarity. ICT, emphasizing WSN (Wireless Sensor Network), remote sensing, cloud computing, AI (Artificial Intelligence), economics, sociology, ethics, and the cooperation with young students in education can play a significant role in research. This study treats these disciplines according to sustainability criteria. The goal is to help management fulfil the most important expectation of reducing the vulnerability of the natural ecosystem. The authors believe that this article may be one of the starting points for a new interdisciplinarity, ALNE.

The catalyst-like role of forensic genetics in the developmental process of Hungarian wildlife forensics
Publication Name: Forensic Science International Genetics Supplement Series
Publication Date: 2022-12-01
Volume: 8
Issue: Unknown
Page Range: 263-264
Description:
The anthropocentric nature of forensic sciences has been changing continuously over the years and this process is continuing today. Due to its universality and multilateral implementation, and the fragmented nature of forensic epistemology, the information provided by forensic genetics can play a pivotal role in forensic science. At the same time, the link between forensic genetics and non-human forensic biological evidence has become unquestionable. It may highlight the modern requirements of forensic science, and this connection is also able to provide useful and sufficient examples for developmental processes in wildlife forensics. Obviously, the local formations, organizations, and operations of wildlife forensics can be different worldwide, but the detection and punishment of wildlife-related criminal behavior, as well as the prevention of further crimes, play a relevant role in these processes everywhere.

Response of wheat to combined application of nitrogen and phosphorus along with compost
Publication Name: Journal of Crop Science and Biotechnology
Publication Date: 2022-12-01
Volume: 25
Issue: 5
Page Range: 557-564
Description:
To achieve food security and increase crop productivity in a sustainable way, keeping soil fertile and balanced fertilization is vital. Soil fertility declining and unbalanced fertilization is one of the bottlenecks to sustainable agricultural production. To overcome these problems, a field experiment was investigated, with the aim of exploring the potential of organic and inorganic nutrient sources with their optimal application and integration for sustainable wheat production. The experiment was conducted in a factorial approach with three replications, where one factor was the level of the NP (Nitrogen and Phosphorus) fertilizer and the other compost, set in a randomized complete block design. Four levels of the N:P fertilizer (control, 27.6%:18.4%, 41.4%:32.2% and 55.2%:46%) were combined with three levels of compost (0, 3 ton/ha and 6 ton/ha), giving 12 treatments combination. From the data collected and analyzed, integrated application of the NP fertilizer and compost significantly increased soil organic carbon, total nitrogen, and available phosphorus but had no effect on soil pH and cation exchange capacity (CEC). Application of 6 ton/ha compost was higher with plant height, spike length, number of seeds per spike, 1000 seeds weight, and biological yield. The sole application of the NP (55.2%:46%) produced (6.19 ton/ha) grain yield whereas combined application of the NP (55.2%:46%) along with the compost (6 ton/ha) produced the higher grain yield (8.16 ton/ha). This clearly revealed that application of 75% recommended inorganic NP fertilizers combined with compost resulted in increased wheat yield by 27.45% over sole application of inorganic fertilizer indicated that the integrated approach could enable to save up to 25% of commercial fertilizers and increase the yield of wheat.

Publication Name: Chemical Engineering Research and Design
Publication Date: 2022-12-01
Volume: 188
Issue: Unknown
Page Range: 265-270
Description:
P-graph is a popularly used framework for process network synthesis (PNS) and network topological optimization. This short communication introduces a Python interface for P-graph to serve as a linkage to modern programming ecosystems. This allows for a wider application of the fast and efficient P-graph solver, to provide structural and topological enumeration in numerous fields. The proposed framework allows for more integrative usage in Artificial Intelligence (AI), machine learning, process system engineering, chemical engineering and chemometrics. Large and repetitive topologies can also be automated using the new programming interface, saving time and effort in modelling. This short communication serves as a demonstration of the newly developed open-sourced P-graph interface.

Slope stabilisation of railway embankments over loose subgrades using deep-mixed columns
Publication Name: Proceedings of the Institution of Civil Engineers Ground Improvement
Publication Date: 2022-12-01
Volume: 175
Issue: 4
Page Range: 247-260
Description:
An investigation was undertaken into the stability of railway embankment slopes over soft subgrades stabilised by deep-mixed columns (DMCs). Three 1:10 scale laboratory embankments were constructed over unreinforced and reinforced subgrade with DMCs in square and triangle patterns. The load-settlement responses of both embankments and columns were measured. The laboratory embankments were then mathematically modelled and the results were compared. After validation, a comprehensive parametric study was carried out to evaluate the factor of safety (FoS) of the embankment side slopes against sliding. Five embankment soil types from poor to high strength, three heights from 1.5 to 10 m and various DMC improvement area ratios from 0 to 65% were considered. The experimental outcomes indicated an increase of nearly 63% in the bearing capacity of both DMC-supported embankments compared with the unreinforced one. Regarding the parametric study, a minimum required FoS of 1.5 was observed for 1.5 m embankments of all soil types stabilised with a 60% improvement ratio. The greatest safety increase was associated with a 1.5 m height embankment with poor soil type, which showed a 36% increase.
