Published: December 2023

Abstract
This study aimed to evaluate the reproductive monitoring activity in Algerian dairy cattle herds. A participatory survey was conducted with 75 veterinarians and inseminators affiliated with the National Centre for Artificial Insemination and Genetic Improvement (CNIAAG). Reproduction monitoring represents a primary activity for 12 % of the veterinarians. Only 10.8 % of veterinarians earn more than 50 % of the yearly global revenue from reproductive activities. 85.3 % of the veterinarians fix the herd monitoring objectives, 64 % use a paper notebook to manage breeding data, and only 22 % establish a reproduction statute inventory. The most requested information before the visit is the last mating (80 %), oestrus (80 %), and calving (90.7 %) dates. Monthly routine fertility visits were practiced by 32 % of the interviewed veterinarians, and only about half of them (52 %) checked the cows systematically at post-partum. The pregnancy diagnosis is practiced by 72 % of veterinarians at 56.71 ± 22.82 days postpartum and confirmed at 91.85 ± 26.94 days postpartum. Furthermore, 73 % of the respondents systematically examined non-pregnant cows after 3 matings; however, only 48 % simultaneously recorded the cows’ body condition score. Regarding postpartum genital pathology control 38.7 %, 22.7 %, and 26.7 % of veterinarians always perform manual transrectal exploration of the genital tract, vaginoscopy, and ultrasonography, respectively. While, 73 % of them examine the cows’ cyclicity when evaluating uterine involution. A substantial proportion of veterinarians included monitoring feed, milk quality/mammary disease, and livestock diseases, in their regular visits. The dairy farmers must be advised of the economic benefits of routine fertility monitoring to achieve good herd reproductive traits.
Cardiac magnetic resonance imaging-derived septum swing index detects pulmonary hypertension: A diagnostic study
Authors: He Miao , Jiang Rong , Fei-Sun  , Cao Jing-Xue , Wang Lan , Shi Jing-Yun 
Published: December 2023

Abstract

Background and Objectives
Because of pressure differences between the pulmonary artery and aorta, the ventricular septum moves in a swinging motion that is commonly observed on cardiac MR (CMR) cine sequences in patients with pulmonary hypertension (PH). We aimed to assess the use of septum swing index (SSI) derived by CMR for detecting PH.

Methods
We retrospectively identified consecutive patients with suspected PH who underwent right heart catheterization (RHC) and CMR at a PH referral center between July 2019 and December 2020. The diagnostic accuracy of SSI for identifying PH (mean pulmonary artery pressure [mPAP] ≥ 25 mmHg) was assessed by receiver operating characteristic curves, sensitivity, specificity, and positive and negative predictive values.

Results
A total of 105 patients (mean age: 47.8 ± 15.0 years; 68 females) were included in the final analysis. SSI and mPAP were negatively correlated in the total study population and patients with PH, but not in patients without PH. SSI was an independent predictor of PH (adjusted odds ratio: 12.9, 95% confidence interval: 3.6 to 45.5, P = 0.003). The area under the curve for SSI was 0.91, with a cut-off value of 0.9673 yielding the best balance of sensitivity (86.4%), specificity (88.2%), positive predictive value (97.4%), negative predictive value (55.6%), and accuracy (86.7%) for detecting PH.

Conclusions
Septum swing index was lower in patients with PH and is a simple, reliable method for detecting PH.
Development, in-house validation and application of a method using high-performance liquid chromatography with fluorescence detection (HPLC-FLD) for the quantification of 12 ergot alkaloids in compound feeds
Authors: Kowalczyk Ewelina , Kwiatek Krzysztof 
Published: December 2023

Abstract

Introduction
Ergot alkaloids (EAs) are toxic substances naturally produced by Claviceps fungi. These fungi infest a wide range of cereals and grasses. When domestic animals are exposed to EAs through contaminated feeds, it is detrimental to them and leads to significant economic losses. For that reason, it is important to monitor feed for the presence of EAs, especially with methods enabling their determination in processed materials.

Material and Methods
Ergot alkaloids were extracted with acetonitrile, and dispersive solid phase extraction (d-SPE) was used for clean-up of the extracts. After evaporation, the extracts were reconstituted in ammonium carbonate and acetonitrile and subjected to instrumental analysis using high-performance liquid chromatography with fluorescence detection. The developed method was validated in terms of linearity, selectivity, repeatability, reproducibility, robustness, matrix effect, limits of quantification and detection and uncertainty. The EA content of 40 compound feeds was determined.

Results
All the assessed validation parameters fulfilled the requirements of Regulation (EU) 2021/808. At least one of the monitored alkaloids was determined in 40% of the samples. The EAs with the highest incidence rate were ergocryptine, ergometrinine and ergocornine. The total concentrations of EAs ranged from under the limit of quantification to 62.3 μg kg−1.

Conclusion
The results demonstrated that the developed method was suitable for simultaneously determining twelve EAs in compound feed and could be used for routine analysis.
Industrial Solid Waste Management in a Metallurgical Plant: Effects of Environmental Rearrangement and Feedback
Authors: Maia Natalia Novais , Haydu Verônica Bender , Sampaio Angelo Augusto Silva 
Published: December 2023

Objective: To evaluate the effect of a contingency arrangement (environmental rearrangement and feedback presentation) in a metallurgical company to increase the likelihood of proper disposal and separation of industrial solid waste.

Theoretical Framework: The incorrect disposal of solid waste in companies produces a series of environmental damages and significantly hampers the effectiveness of reverse logistics.

Method: Two owners and all employees of a metallurgical company in Paraná, Brazil, participated. The procedure consisted of three stages: (1) analysis and detailed description of the current disposal conditions before the intervention; (2) strategic rearrangement of containers for waste disposal location, accompanied by a weekly record of the types of waste discarded during the intervention; and (3) installation of informative signs providing monthly feedback on the quantity of waste discarded.

Results and Conclusion: The structural rearrangement of the environment, with the strategic placement of containers in easily accessible locations and the inclusion of signs identifying the types of waste in each of them, coupled with regular feedback on the quantity of waste disposal from the metallurgical plant, resulted in a highly effective management of solid waste in the company. We concluded that the intervention improved the company’s industrial solid waste management and expanded the reverse logistics practice.

Implications of the Research: The intervention contributed to local-level management, which could inspire similar changes in the socio-environmental management practices of other organizations.

Originality/value: The study contributes to scientific advancement by proposing the contingency arrangement based on Behavior Analysis principles.
ANTHROPOGENIC CENTERS AS INDICATORS OF THE ECOLOGICAL STATE OF THE ENVIRONMENT
Authors: Denysyk Grigoriy , Voyna Inna , Denysyk Bohdan 
Published: December 2023

At the beginning of the XXI century. the landscape and ecologically destabilized environment of any region, including Ukraine, is characterized by abnormally rapid changes in the structural organization of geocomponents and landscape complexes and the relationships between them. As a result, new phenomena arise in the reaction of these natural structures to external, mainly anthropogenic, influences, which lead to unpredictable trends in the development of the environment. In such conditions, various anthropogenic centers are actively developing, among which the role and importance of recreational ones is also increasing.
As previous studies show, anthropogenic centers are the most real indicators of the current ecological state of the environment. Knowledge of the processes and phenomena that develop in recreational centers and geoecotones is relevant and promising. On the one hand, they reveal the causes and mechanisms of existing trends of recreational transformations at the local level, and on the other, taking into account their indicator value, they open the way to managing the state of recreational landscapes and, partially, the environment in general
In the conditions of today's unstable environment, anthropogenic centers and processes in them are gaining widespread development, as a manifestation of new landscape, energy, substance and informational connections. The goal is to investigate the formation process and substantiate the significance of anthropogenic centers as indicators of environmental development. In the research process, a constructive landscape approach, the principles of complexity and natural-anthropogenic coexistence were applied; methods - retrospective, natural analogies, modeling, GIS technologies. By the anthropogenic center we understand the territory within which, under the influence of human activity, processes develop that lead to a change in the structural organization of geocomponents and landscape complexes. It is shown that the diversity of anthropogenic centers and the processes that develop in them depend not only on the type of economic activity, but also on the mosaic of landscape complexes on the basis of which anthropogenic centers are formed. On the example of the model region - Middle Pobuzhzhia, the process of formation and structure of recreational centers - recreational centers in the coastal zone of the South Bug River and residential centers in forest landscapes were studied. Taking into account the indicator value of processes developing in anthropogenic centers, the possibilities of using these peculiar landscape structures in the development of regional projects of rational nature management are considered. It is noted that in the future it is necessary to intensify the research of anthropogenic centers and their processes, center boundaries and paradynamic relationships with the environment.
Keywords: anthropogenic landscape, anthropogenic center, processes, indicators, structure, environment, rational nature management.
Ecological consciousness in the works of writers of small peoples of Russia (on the example of Yu. Rytheu, E. Aipina, Yu. Shestalov)
Authors: Cheng Shuangting 
Published: December 2023

The article analyzes the ecological consciousness in the works of writers of the small peoples of the North of Russia. The subjects of the study are the works of Yu. Rytheu, E. Aipina. Yu. Shestalov. Unlike ecological works, ecological consciousness in the works of these writers is more connected with national continuity and cultural heritage. Globalization and modernity have had a huge impact on all spheres of development of national minorities, and they were forced to integrate into the modernization process, whether through active choice or passive acceptance.Modern economic means of industrialization, programming and rationing have an impact on the traditional ways of supporting ethnic minorities. Writers from small nations, as representatives of the advanced intelligentsia of various ethnic groups, were the first to feel this crisis and expressed their concern in their works. This article mainly uses the method of text analysis to analyze ecological consciousness in the work of writers from small peoples. The main contribution of the author is that he offers new methods of studying the literature of small peoples. Ecological consciousness in the works of writers of national minorities differs from other ecological literary works. Ecological consciousness in the works of writers of ethnic minorities is ultimately a matter of survival and sustainability of an ethnic group. At a time when the problem of globalization and modernity is becoming obvious, writers from ethnic minorities use their own literary works to raise this environmental alarm and arouse readers' attention to this problem. The author analyzes the works of writers belonging to small peoples, pointing out the various means and ways in which writers express their ecological knowledge.
Wall-Modeled Large-Eddy Simulation of Turbulent Boundary Layer with Spatially Varying Pressure Gradients
Authors: Hayat Imran , Park George Ilhwan 
Published: December 2023

Wall-modeled large-eddy simulations of turbulent boundary layers subjected to spatially varying streamwise pressure gradients are conducted to assess the predictive performance of three wall models: ordinary differential equation equilibrium, integral nonequilibrium, and partial differential equation (PDE) nonequilibrium models. The test case is based on experiments conducted by Volino (Journal of Fluid Mechanics, Vol. 897, Aug. 2020, p. A2), where the flow is subjected successively to zero pressure gradient (ZPG), favorable pressure gradient (FPG), recovery ZPG, and adverse pressure gradient (APG) regions. Skin friction is overpredicted in FPG by all the wall models. For equilibrium and integral models, this overprediction is attributed to the strong deviation of mean velocity profiles within FPG from the log law, used explicitly in the equilibrium and implicitly in the integral model. The overprediction is more pronounced for the PDE model, which is attributed to dynamic correction of wall-model eddy viscosity for resolved stresses and a lack of correction for pressure gradient. Potential remedies to mitigate this problem are proposed. Grid refinement improves wall-stress predictions in both FPG and APG but only affects the outer profiles in APG, revealing that accurate wall-flux modeling is more critical for APG. Anisotropic grid analysis shows streamwise grid refinement to be more crucial than spanwise for the convergence of skin-friction, outer velocity, and Reynolds stress profiles.
An increase in hydrocarbon reserves of Andylakhskoye gas condensate field (Yakutia) taking into account the specifics of its geological structure
Authors: Rudykh I. V. 
Published: December 2023

As a result of the research; a conclusion was made about the high prospects for the growth of gas reserves of Andylakhskoye gas condensate field- located within the Loglor swell of the Vilyui syneclise of the Sakha Republic (Yakutia). An increase in reserves is expected; both due to previously discovered deposits and new; more promising horizons located in the Permian deposits.It is proposed to set up seismic surveys using the 2D common depth point method within the field and the adjacent; most promising areas to increase investment attractiveness; the rational use of natural resources; and increasing gas reserves of Andylakhskoe gas condensate field. According to the results of the studies carried out in this article; the prospects for the growth of hydrocarbon reserves of Andylakhskoe gas condensate field are estimated by over 10 times of the amount.
Resource Mobilisation, Utilisation and Wellbeing of Social and Solidarity Groups In The Assin Fosu Municipality, Ghana.
Authors: Koomson F. , Buadu C. , Ntiri R. O. 
Published: December 2023

Purpose: The study focused on farm-based cooperatives in the Assin Fosu municipality and examined resource mobilisation as well as the factors that determine resource utilisation and the wellbeing of social and solidarity organisations.
Design/Methodology/Approach: 180 respondents from six registered farm-based cooperatives in the Assin Fosu Municipality were chosen for the study using a mixed research design and a multi-stage sample method that included purposive, proportional, and simple random sampling procedures. The Focus Group comprised cooperative chairpersons and was further expanded to include the Municipal Co-operative Officer, who was specifically chosen as a key informant. In addition to narratives drawn from qualitative data, descriptive statistics and logistic regression were used to examine the data.
Research Implications/Limitations: The limitation of this study is the measurement of farm size and income which were based on the mental construct of farmers because most of the cooperative members did not keep records. This tended to distort the reality related to farm size and income which were included in the construct of wellbeing and collective resource mobilisation.
Findings: We discovered that, except for cooperatives based on cocoa, resource mobilisation was low across all the cooperatives. The study found that the mobilisation of resources and the collective purchase of agricultural equipment and supplies, which reduced production costs, were the driving forces behind resource utilisation. The main wellbeing indicators were longer membership durations and group resource mobilisation and utilisation.
Practical Implications: The findings of the study will help contribute to the management of social and solidarity groups in Ghana and broaden the understanding of how this development approach affects livelihoods. It is also hoped that the findings will contribute to the mitigation of the cost of neoliberal policies by providing a path to wellbeing at the micro and informal levels through group resource mobilisation and utilisation.
Social Implications: Social and Solidarity organisations serve as an alternative to economic organisations that are based on neoliberal principles. This is because the latter favours the dominant few in developing economies culminating in widespread poverty, inequalities, and a decline in wellbeing. To maximise wellbeing, cooperatives should intensify resource mobilisation, and utilisation whilst maintaining their membership.
Originality/Value: The novelty of this paper lies in its contribution to the literature on social and solidarity economies. It provides information on the missing link on how farm-based cooperatives mobilise and utilise resources for the wellbeing of their members.
Ocena „in abstracto” i ocena „in concreto”
Authors: Leduc Fabrice Leduc 
Published: December 2023

Przedmiot badań: Ustawodawca posługuje się wieloma niedookreślonymi pojęciami, zwanymi standardami (por. wina, siła wyższa, uzasadnione przekonanie, wady ukryte, przewidywalność szkody, istotna dysproporcja itp.). Każdorazowo standard polega na ocenie zachowania lub sytuacji poprzez porównanie jej z modelem referencyjnym w celu ustalenia, czy dane zachowanie czy też sytuacja są prawidłowe, czy nie. Aby skonstruować ten model referencyjny, sędzia ma do dyspozycji dwie możliwe metody oceny: ocenę in concreto i ocenę in abstracto. To rozróżnienie, choć powszechnie stosowane, nie jest w pełni skonceptualizowane. Celem tego artykułu jest doprecyzowanie, w oparciu o prawo francuskie, tych dwóch sposobów oceny. Artykuł, choć dotyczy prawa francuskiego, może zainteresować polskich prawników, gdyż porusza problematykę obecną we wszystkich porządkach prawnych.
Cel badawczy: Na poziomie teoretycznym celem jest lepsze zrozumienie rozróżnienia pomiędzy oceną in concreto i in abstracto na poziomie praktycznym, zaś określenie dla każdego standardu odpowiedniego trybu oceny.
Metoda badawcza: Przyjęto podejście analityczne polegające na analizie orzecznictwa dotyczącego poszczególnych standardów, aby następnie wyciągnąć wnioski o bardziej ogólnym charakterze.
Wyniki: Ocena in abstracto polega na ocenie standardu poprzez odniesienie go do wzorca zewnętrznego w stosunku do podmiotu, którego ocena dotyczy. Ocena in concreto natomiast polega na ocenie standardu przez odniesienie do wzorca, którym jest (zachowanie) sam(ego) podmiot(u), do którego standard ma zastosowanie.
Ocena in concreto, ze względu na to, że za standard przyjmuje zachowanie samego podmiotu podlegającego osądowi, będzie uprawniona jedynie wówczas, gdy celem normy będzie ochrona tego podmiotu; w przeciwnym razie należy zastosować ocenę in abstracto. W ramach każdej z dwóch podstawowych metod oceny zachodzi podział wewnętrzny.
Ocena in concreto może mieć charakter psychologiczny lub odnosić się do faktów. Ocena psychologiczna in concreto polega na odwołaniu się do tego, co oceniany podmiot myśli, w co wierzy lub co odczuwa. Ocena in concreto oparta na faktach odwołuje się do tego, jak zwykle zachowuje się oceniany podmiot.
Ocena in abstracto może być prosta lub bardziej wyrafinowana. Prosta ocena in abstracto polega na ocenie standardu poprzez odniesienie do jednego wzorca zewnętrznego: rozsądnej osoby.
Ocena bardziej wyrafinowana in abstracto polega z kolei na ocenie standardu poprzez odniesienie do modelu zewnętrznego udoskonalonego w tym sensie, że jest on skonstruowany przy użyciu jednej lub większej liczby cech ocenianego zachowania (patrz: ocena zachowania profesjonalisty w porównaniu z zachowaniem typowego profesjonalisty w tej samej branży).
Nabycie przez occupatio posiadania pożytków naturalnych ziemi i produktów zwierząt według teorii Leona Pinińskiego. Część 3
Authors: Skrzywanek-Jaworska Dagmara 
Published: December 2023

Przedmiot badań: Przedmiotem badań jest nabycie posiadania pożytków naturalnych ziemi (Besitzerwerb an Feldfrüchten) oraz produktów zwierząt (Besitzerwerb an Thierprodukten) według teorii possessio Leona Pinińskiego. Jest to ostatni z serii artykułów poświęconych rozważaniom polskiego romanisty na temat samodzielnego nabycia posiadania ruchomości w drodze occupatio.
Cel badawczy: Celem badawczym jest przybliżenie opracowanej przez Pinińskiego koncepcji possessio w rozumieniu gospodarczego związku człowieka z rzeczą oraz charakterystyka naukowego wizerunku polskiego romanisty na tle działalności pandektystów i innych przedstawicieli ówczesnej, niemieckojęzycznej nauki prawa.
Metoda badawcza: W artykule zastosowana została metoda historyczno-prawna.
Wyniki: Aktualne pozostają wnioski sformułowane wcześniej odnośnie do rozważań o nabyciu przez zawłaszczenie posiadania dzikich zwierząt (Część 1) oraz plastrów miodu i ukrytych w ziemi kosztowności (Część 2). Można je uzupełnić wnioskiem ogólnym. Naukowa aktywność Pinińskiego na tle XIX-wiecznej, zdominowanej przez pandektystów, niemieckojęzycznej doktryny zasługuje na uwagę nie tylko romanistów prawniczych, ale także dogmatyków obowiązującego prawa. Autor, którego dorobek jest doceniany i cytowany w europejskiej literaturze przedmiotu, w polskiej doktrynie pozostaje prawie niezauważony. Tymczasem każda alternatywna wersja teorii, na której opiera się system obowiązującego prawa – w tym wypadku teoria possessio – nadal nowi źródło naukowej inspiracji, nie tylko dla historyka prawa.
