Objective: To describe the experience of the UTH-Bogodogo obstetrics and gynecology department in ultrasound determination of fetal sex in the first trimester of pregnancy.
Patients and methods: This was a prospective descriptive study conducted over a 30-month period from February 1, 2021 to June 30, 2022 in the gynecological and obstetric ultrasound unit of the UTH-Bogodogo in Ouagadougou. The study sample consisted of 311 fetuses. The sample included all pregnant women who came for an obstetrical ultrasound scan in a non-emergency situation, whose gestational age was between the 11th and 14th week of amenorrhea, and who expressed a wish to know the fetal sex. The methods described by Mazza and Efrat were used to determine fetal sex. Patients were followed until delivery, after clinical verification of the sex of their newborns. Data were collected using an individual data collection form. Participation in the study was conditional on patients signing an informed consent form.
Results: Fetal sex determination was possible in 280 of 311 fetuses, for a feasibility rate of 89.7%. In the remaining 31 cases, it was not possible to determine the fetal sex, as the position of the fetus did not allow a clear view of the genital bud. In terms of reliability, of the 238 fetuses monitored, fetal sex determination was correct in 204 fetuses, for a success rate of 85.7%. Accuracy was better when sex determination was performed after 12 weeks of amenorrhea. There was no significant difference in measurements between single and multiple fetuses.
Conclusion: ultrasound determination of fetal sex at first birth could be an effective, simple, available and inexpensive option in developing countries.
The effect of the Public Order Act of 1994, (Act 491) on Democracy in Ghana
Authors: Norman Ishmael D.
Published: October 2024

Background: The thirty-year-old Public Order Act of Ghana of 1994 (Act 491), is seen as archaic legislation over the people’s civil libertarian rights to assemble in protest against inimical and corrupt government actions. It has become the bane of democratic development in Ghana, preventing the citizens right to conduct non-violent civil disobedience acts,  and seen as anti-establishment act. Methods: This is an exploratory as well as retrospective review of government security apparatchik’s interpersonal relationship with the Ghanaian public who engage(d) in non-violent demonstrations and protests since the promulgation of the act. Results: The assessment revealed that, for the average Ghanaian citizen, his or her only means of getting the attention of government is through public demonstration or protest. The Parliamentarians for their constituencies are disconnected from them giving them no avenue for the redress of grievances. It also found that, the international development partners operating in Ghana are perceived to be siphoning the life-blood out of the people of Ghana, sort of domestic economic hit men, who promote Ghana as a democracy despite the realities on the ground, due to the effect of their role on increasing income inequalities among the populations. Conclusion: Despite the persistent denial of the public’s right to assemble and protest against government conduct: corruption, stealing, extravagant living and spending, denial of meritocratic job placement, and the harm caused to their freedoms, the international development partners and nations continue to issue endorsements to the government as running a democratic system, despite evidence-based corruption, indebtedness to both international and domestic creditors and poor socio-economic outcomes for the people of Ghana due poor leadership and management of the economy.

Published: October 2024

A schwannoma is a tumour of the nerve sheath .Tumour arises from the schwann cells. Most of the schwannoma are benign in nature presenting as a slow growing asymptomatic solitary neck mass. It rarely undergoes malignant transformation [1%] . Most commonly schwannoma originates from the vestibular nerve. Our case is a 60 yr male patient, presented with a painless swelling in the neck since 2 yrs.

A non-tender, oval, firm in consistency in the right lower half of the neck, between two bellies of right sternocleidomastoid. Right common carotid artery was displaced, cough reflex present on palpating the swelling. IDL was normal. FNAC showed chronic inflammatory cyst. CT scan showed a well-defined cystic lesion in right lower carotid space with perceptible wall & thin non enhancing septations in relationship to adjacent structures. The lesion which had displaced the IJV & CCA. Excision of the swelling was done under general anesthesia. Histopathology showed Antoni type B Schwannoma.Post operative period was uneventful.

Authors: M P Ramprashanth , B T Sangamesh , C R Shivakumar , Katti Pranesh B
Published: October 2024

Objectives

Case cancellation is a new and upcoming quantitative measurement of the standard of surgeries being done in the hospital.

Material and Methods

Prospective data analysis from January 2018 to December 2023 of the cases being cancelled in our department.

Results

A total of 913 cancelled cases out of 7021 cases amounted to a case cancellation rate of 13%. Case cancellation was more common among men. Patients aged 61—70 years were most susceptible to cancelling cases.

Conclusion

The case cancellation rate reflects the quality of surgeries at the health centre. High rates suggest poor management, staff shortages, and overburdened doctors.

Published: October 2024

Background

Untreated co-occurring substance use and substance use disorders (SUDs) in patients with medical conditions may be associated with unfavourable medical outcomes. Understanding the prevalence of substance use and SUDs among patients admitted to hospital for medical illness may help in developing appropriate strategies to manage SUDs in this population and improve the outcomes of medical illness. We assessed the prevalence of substance use and SUDs among patients admitted for medical illnesses and the association between substance use and medical illness.

Methods

This cross-sectional study was done in an in-patient setting in a multidisciplinary teaching medical institution in India. Using systematic sampling, adult patients admitted in various departments for at least 24 hours were interviewed using standard instruments by psychiatrists trained in the study methodology.

Results

Two hundred and ninety patients participated. Their mean (SD) age was 42.2 (15.6) years. One hundred and nine participants (37.6%) reported lifetime use of any psychoactive substance, with tobacco being the most common substance used (91, 31.4%), followed by alcohol (69, 23.8%) and cannabis (12, 4.1%). Lifetime alcohol use was significantly associated with diseases of the circulatory system. Lifetime use of any substance or of alcohol, and current use of any substance or tobacco were significantly associated with injuries, poisoning and other consequences of external causes.

Conclusions

A large proportion of patients hospitalized for medical illness reported the use of psychoactive substances or had SUDs. The use of some of these substances was also associated with injuries as well as diseases of the circulatory system.
V.R. Khanolkar’s initial years as pathologist and researcher in India: 1924–1941
Authors: PAI SANJAY A. , LANJEWAR DHANESHWAR N. , JOSHI AMITA S.
Published: October 2024

Vasant Ramji Khanolkar was the first Indian pathologist and a pioneering researcher who was at the forefront of the diverse fields of cancer research, blood group genetics, epidemiology and leprosy research, etc. in the mid-twentieth century. All his cutting-edge research took place after he joined Tata Memorial Hospital, Bombay (now Mumbai), as Director of Laboratories. There is little evidence of his research in the first 17 years of his career in India, at J.J. Hospital and K.E.M. Hospital, Bombay. We tried to address this gap by attempting to obtain information on Khanolkar’s papers from PubMed, prior to his having joined Tata Memorial Hospital. We evaluated the abstracts of the presentations that he made at the meetings of the Teaching Pathologists Association, Bombay. Finally, we extracted from the autopsy registers at the two hospitals, any useful information about the autopsies that he had performed.

Khanolkar performed preliminary laboratory research in anaemia as well as some experimental pathology in his stint at K.E.M. Hospital. Further, surprisingly, histology was not performed on most autopsies at J.J. Hospital for the period that he was Professor, but was done at K.E.M. Hospital. Why Khanolkar was a late bloomer and did not perform much research or publish in the first two institutions that he was Professor at, remains a mystery.

Published: October 2024

Background

We initiated a conversation regarding the concept of professional identity formation (PIF) with faculty of Institute of Nursing at our university through a participatory workshop. We report the planning and conduct of the workshop, as well as lessons learnt from the discussions in the workshop.

Methods

We designed and implemented a day-long workshop for 28 nursing faculty at Institute of Nursing, Bhaikaka University, Gujarat. The expected learning outcomes of the workshop were to: (i) understand the concept of PIF and process of socialization; (ii) identify factors influencing socialization; and (iii) discuss strategies to support PIF. The workshop included a series of four small group discussions, each followed by debriefing. We collected feedback using a questionnaire with 4 open-ended questions and written reflections on the learnings, within 2 days of the workshop. We carried out manual content analysis of text data generated during group work, reflections and feedback.

Results

Twenty-six of the 28 participants responded to the questionnaire. Thirteen mentioned interactions during group activities and discussions with facilitators as a good part of the workshop. Constructive suggestions on improving the workshop were received from 13 respondents. Twenty-three respondents reported they would make changes in their practice after the workshop. Five respondents found the activity on roles and responses during socialization as needing more discussion. Key themes identified from the participants’ reflections were: (i) their different views about professional identity, (ii) experiences and reactions and (iii) their future action plan.

Conclusions

The workshop was well received by the participants. Our approach to the workshop might help other institutions design and implement similar activities as a part of their faculty development programme.
Core Flipping in Lead Optimization: Rank Ordering using Multisite λ Dynamics
Authors: Gartan Parveen , Brooks III Charles L. , Reuter Nathalie
Published: October 2024

In structure-based drug discovery, reliable structural models of ligands bound to their target receptor are critical for establishing the structure activity relationship of congeneric series. In such a series, substitutions on a common scaffold core might lead to different binding modes, ranging from slight changes of orientations to flipping or inversion of the core structure. Moreover, molecular docking might lead to alternative orientations within the top ranked poses without being able to discriminate which is the most likely. To determine the relative binding affinities between two alternative ligand poses, we propose a methodology based on relative binding free energy calculations using the multisite λ dynamics method. We use a dual-topology approach with distance restraining schemes. We introduced a novel strategy using one-step perturbation to calculate the contributions of the applied restraints. While using FEP/MBAR instead for that purpose led to smaller uncertainties it suffered from convergence issues. We test the validity and predictive power of our approach using two pharmaceutically relevant targets and eight compounds from experimentally characterized congeneric series. For each target, our approach correctly ranks the known X-ray poses to be more favorable than alternative flipped poses. The proposed methodology can be easily extended to rank more than two poses in a single simulation and should also be applicable for the prediction of conformational binding cliffs, ranking fragments, core hopping cases and evaluating different scaffold binding to a common target.

Helical foldamers constitute particularly relevant targets in the field of host-guest chemistry, be that as hosts or substrates. In this context, the strategies reported so far to control the dimensions and shape of foldamers mainly involve modifications of the skeleton through covalent synthesis. Herein, we prepared an oligopyridine dicarboxamide foldamer substituted by photo-active tetraphenylethylenes (TPE). We demonstrate that it is possible to toggle the length of a helical foldamer by two means. First, the elongation of foldamers can be tuned by adjusting the concentration, as demonstrated by DOSY NMR spectroscopy and X-ray diffraction analyses on both the single and the double helix structures. Secondly, and in a more original manner, a photo-induced protonation process triggered by TPE units promotes a novel pathway to unfold helical foldamers, leading to dramatic conformational and spectroscopic changes.
Competitive Strain Modulation of Oxygen Reduction Reaction in Monolayer Binary Alloy Surfaces
Authors: Ozório Mailde S. , Frahm Nygaard Marcus , Rossmeisl Jan
Published: October 2024

Binary alloys of transition metals are promising catalytic materials for the cathodic oxygen-reduction reaction (ORR) of polymer-electrolyte-membrane fuel cells (PEMFCs). However, a lack of understanding of the factors that affect the ORR's catalytic performance hampers the catalytic applications of binary alloys. To obtain further knowledge of binary alloys for efficient ORR, we investigate the activity of monolayer AuxPt1-x alloy surfaces supported on Pt(111), considering from random distribution until phase-segregated surface atoms. Using the *OH adsorption energy as a descriptor, we found that the activity of monolayer binary alloy surfaces depends on the distribution of the surface atoms within surfaces with segregated Pt and Au domains showing higher activity. The adsorption energy of *OH increases with the fraction n of Au near the adsorption site and decreases with the fraction p of Au outside the heptamer. The energy increase due to n is related to a tensile strain, while the decrease with the increase of p is due to a long-range surface strain effect on the Pt-Pt and Pt-Au bonds, improving the activity of the available Pt adsorption sites. Due to the weak *OH adsorption energy on Au sites, an Au overall percentage considerably above the Pt percentage starts to reduce surface activity because of the reduction of the number of very active Pt sites.

Stereoselective hydroaminoalkylation of alkenes via α-C–H bond activation of alkylamines is an efficient process for the preparation of complex alkylamines minimizing stoichiometric waste. Herein, we report that a combination of Cp*TiMe3 and AlMe3 catalyzes the branch-selective hydroaminoalkylation of 1-alkenes, including styrene derivatives and 1,3-dienes, with N-methylaniline derivatives. Kinetic studies reveal that the active species are generated from in situ generated Cp*TiMe2(NMePh) and alkylaluminum. Continuous wave (CW) and pulse EPR spectroscopy show that multiple Ti(III) species, bearing amido and most probably alkyl ligands as well as an Al center, are formed, paralleling catalytic activity. Based on these findings complemented by DFT studies, we propose a reaction mechanism featuring d1 Ti(III) three-membered azatitanacycle species with amidoaluminate anions as active species. The alkene insertion into the Ti–C bond of the three-membered metallacycle intermediate is a key step that drives selectivity. This step favors the branched product through both steric and electronic effects, namely by i) minimizing steric repulsion between the styrene phenyl ring and the Cp*/Al moieties and ii) spin delocalization from metal to substrate antibonding orbital, which stabilizes the transition state resulting in facile insertion into M–C bond.
О некоторых тождествах в газовой динамике
Authors: Шеретов Юрий Владимирович
Published: October 2024

Доказаны три тождества, которым подчиняются макропараметры идеального политропного газа. С их помощью установлена эквивалентность двух различных форм записи нестационарной системы Эйлера на классе непрерывно дифференцируемых функций. Показано, что любое бесконечно дифференцируемое решение стационарной системы Эйлера при некоторых дополнительных условиях является также решением стационарной системы Навье-Стокса и стационарной квазигазодинамической системы.

Three identities that govern the macroparameters of an ideal polytropic gas are proven. With their help the equivalence of two different forms of writing the non-stationary Euler system on class of continuously differentiable functions is established. It is shown that any infinitely differentiable solution of a stationary Euler system under some additional conditions is also a solution of stationary Navier-Stokes system and stationary quasi-gas-dynamic system.
Модель оценки степени уникальности и восстановления слабо-определенных данных на основе модификации нейронной сети APT-2
Authors: Гатин Руслан Ришатович , Новикова Светлана Владимировна
Published: October 2024

В статье рассматривается задача анализа и восстановления данных в малых выборках со слабо изученными взаимосвязями, названными авторами слабо-определенными данными. Предложен метод, основанный на известной нейросетевой модели классификации АРТ-2, способный как производить непосредственно классификацию, так и определять степень уникальности входного вектора по отношению к имеющейся выборке с учетом особенностей слабо-определенных данных. Также разработана модификация предложенного метода, позволяющая восстанавливать пропущенные атрибуты в векторах слабо-определенных данных в случае наличия векторов с полными данными в соответствующем классе. Проведены численные эксперименты для слабо-определенных данных о содержании металлов в крови детей в возрасте от 1 до 14 лет, проживающих на территории г. Казани. Эксперименты продемонстрировали эффективность разработанных методов.

The article examines the problem of analyzing and recovering data in small samples with poorly studied relationships, called weakly defined data, by the authors. A method is proposed based on the well-known neural network classification model ART-2, capable of both direct classification and determining the degree of uniqueness of the input vector about the existing sample, taking into account the characteristics of weakly defined data. A modification of the proposed method has also been developed that makes it possible to restore missing attributes in vectors of weakly defined data in the case of the presence of vectors with complete data in the corresponding class. Numerical experiments were carried out for weakly defined data on the content of metals in the blood of children aged 1 to 14 years living in Kazan. Experiments demonstrated the effectiveness of the developed methods.

Anarchokapitalistyczna wizja bezpieczeństwa: wojna jako narzędzie państwowej dominacji
Authors: Żmudzińska Karina
Published: October 2024

Przedmiot badań: Przedmiotem badań jest anarchokapitalistyczna wizja bezpieczeństwa zewnętrznego. Obejmuje to analizę tego, w jaki sposób anarchokapitaliści postrzegają rolę państwa w generowaniu konfliktów zbrojnych oraz ich krytykę państwa jako głównego podmiotu odpowiedzialnego za prowadzenie wojen. W badaniu rozważane są również konsekwencje istnienia państw i wojny dla globalnego bezpieczeństwa, w tym zagrożenie nuklearne.
Cel badawczy: Celem badawczym jest zbadanie, czy anarchokapitalistyczna koncepcja bezpieczeństwa zewnętrznego, oparta na aksjomacie nieagresji i postulacie eliminacji państwa jako źródła przemocy, może być realną alternatywą dla państwocentrycznej perspektywy bezpieczeństwa. Badanie dąży do oceny, czy wizja ta ma zastosowanie praktyczne w rzeczywistym świecie, czy jest jedynie utopijną teorią.
Metoda badawcza: Podstawową metodą jest analiza tekstów przedstawicieli myśli anarchokapitalistycznej, w tym przede wszystkim Murraya Rothbarda.
Wnioski: Anarchokapitaliści krytykują państwo jako źródło konfliktów, podkreślając, że monopol na przemoc prowadzi do eskalacji wojen. Uważają, że wojny służą jedynie umacnianiu władzy elit, a nie społeczeństwu. Szczególną uwagę zwracają na zagrożenie nuklearne, postulując rozbrojenie, ponieważ wojna nuklearna nie ma zwycięzców. Choć ich wizja bywa uznawana za utopijną, anarchokapitaliści, z Murrayem Rothbardem na czele, wierzą, że stanowi realistyczną alternatywę dla państwocentrycznego modelu bezpieczeństwa, opartą na dobrowolnych relacjach i nieagresji.

Sosyotropik ve Otonomik Kişilik Özelliklerinin İletişim Becerilerine Etkisi (The Impact of Sociotropic and Autonomous Personality Traits on Communication Skills)
Authors: Gürsel Merve
Published: October 2024

Bu makale, sosyotropik ve otonomik kişilik özelliklerinin iletişim becerileri üzerindeki etkilerini incelemektedir. Sosyotropik kişilik, bireylerin diğer insanlarla ilişki kurma, başkalarına duyarlılık gösterme ve sosyal bağımlılık eğilimlerini yansıtırken, otonomik kişilik, bireyin bağımsızlık, özdenetim ve bireysel hedeflere odaklanma eğilimlerini ifade etmektedir. Her iki kişilik özelliğinin iletişim becerileri üzerindeki etkileri, farklı psikolojik kuramlar çerçevesinde ele alınmıştır. Sosyotropik özelliklere sahip bireyler, genellikle empatik ve işbirliğine dayalı bir iletişim tarzı geliştirirken, otonomik özellikler, bireylerin daha bağımsız, kararlı ve kontrol sahibi bir iletişim tarzı benimsemelerine yol açabilir. Çalışma sonucunda, sosyotropik ve otonomik kişilik özelliklerinin iletişim becerilerine farklı yönlerden katkı sağladığı ortaya konulmaktadır. Bu bağlamda, kişilik özelliklerinin derinlemesine anlaşılması, bireyler arasındaki etkileşimi optimize etmek ve etkili iletişim stratejilerinin geliştirilmesine katkı sağlamak amacıyla önem taşımaktadır.

A erosão do solo é um fenômeno natural que desempenha um papel na configuração da paisagem e é influenciado por diversos fatores, tais como clima, relevo, tipo de solo, cobertura vegetal, geomorfologia e inclinação do terreno. No entanto, sua intensificação ocorre devido à ação humana não planejada, conhecida como 'mudanças de uso da terra'. Neste estudo, o objetivo foi analisar a vulnerabilidade ambiental à erosão do solo na ilha de São Luís, considerando a interferência sazonal, utilizando um método baseado na álgebra de mapas. Os resultados revelaram a significativa influência do clima e dos manguezais na ilha, em quatro cenários distintos. As estações mais vulneráveis foram identificadas como verão e outono, associadas aos períodos mais chuvosos na Amazônia brasileira. Assim, a utilização de estações meteorológicas como ferramenta de monitoramento emergiu como um aspecto crucial neste estudo. Portanto, a implementação de uma rede de drenagem urbana adequada e adaptada ao cenário urbano, diretamente impactado pelo rápido crescimento populacional, é uma medida prioritária. Isso visa evitar que eventos de chuvas intensas transformem a região em ambientes propícios a desastres.

As Redes Neurais Artificiais (RNAs) têm sido empregadas em diversas aplicações, destacando-se como um poderoso recurso para analisar dados e resolver problemas em diversas áreas do conhecimento. Na modelagem de superfícies, as RNAs desempenham o papel de um método de interpolação espacial. Entretanto ao empregar as redes neurais, as predições dos valores de altitude não vêm acompanhadas de suas correspondentes incertezas. Nesta contribuição, fornecemos o aprimoramento das estimativas de RNAs em uma abordagem inovadora, aplicando um método de reamostragem para prever intervalos de altitudes em vez de uma única estimativa, como é comumente realizado por técnicas convencionais. Uma rede Perceptron de Múltiplas Camadas (MLP) foi usada para prever os intervalos de altitudes com base nas coordenadas dos pontos coletados em campo por Posicionamento Cinemático em Tempo Real (RTK). A rede foi treinada e validada usando o método de reamostragem Repeated Leave-One-Out Cross-Validation (RLOOCV), uma extensão do clássico método Leave-One-Out Cross-Validation (LOOCV), que ao realizar diversas iterações permite a captura da aleatoriedade associada à rede neural, incluindo fatores como arquitetura, inicialização e procedimento de aprendizado. As métricas de desempenho revelaram resultados satisfatórios na estimativa de altitudes, apresentando valores de Raiz do Erro Quadrático Médio (RMSE) consistentes, com a média global de RMSE, RMSE máximo e RMSE mínimo de 0,081 m (± 0,002), 0,520 m e 0,027 m, respectivamente. Embora essa metodologia tenha apresentado um desempenho satisfatório, a análise espacial revelou desafios na generalização em áreas vertentes, de talvegue e com variações abruptas na inclinação do terreno.

Das 15 metrópoles brasileiras, 10 estão sob o domínio da Mata Atlântica. Neste sentido, o fenômeno da metropolização suprimiu o bioma em fragmentos florestais, sobretudo nas zonas próximas ao litoral. Com isso, as Geotecnologias se apresentam como ferramentas promissoras na análise e monitoramento das florestas urbanas. Dessa forma, o objetivo deste estudo consistiu em propor a estimativa e análise da biomassa florestal acima do solo (BAS) mediante geotecnologias. Os sítios selecionados correspondem às Unidades de Conservação mata de Dois Irmãos, mata Curado/Jardim Botânico e a mata do Engenho Uchôa, situadas no município do Recife, Pernambuco. Para execução deste trabalho, foi adquirida nuvem de pontos LiDAR junto à Prefeitura do Recife. Para estimar a biomassa foi feita dendrometria em 31 indivíduos arbóreos. A partir da nuvem de pontos construiu-se o Modelo Digital de Terreno (MDT) e o Modelo Digital de Copa (MDC).  Posteriormente, foi realizada uma correlação entre a BAS estimada a partir de LiDAR, e a altura das árvores aferida sobre o modelo digital, em que se obteve um coeficiente de Pearson = 0,8. Com base nestes resultados, se estruturou uma equação para estimar a biomassa florestal total, utilizando como variável o MDC. A estimativa da biomassa florestal total da mata de Dois Irmãos resultou em 169,9 Gg, a da mata do Jardim Botânico, em 25,27 Gg e da mata de Engenho Uchôa, num total de 9,86 Gg. Considera-se, portanto, que o uso integrado das Geotecnologias responde bem à estimativa e monitoramento da biomassa florestal.

Published: October 2024

This study aims to solve the inverse problem for determining the heterogeneity of an object. The scattered ﬁeld was measured outside its boundaries at a set of observation points. Both the radiation source and observation points were assumed to be located outside the object. The scattered ﬁeld was modeled by solving the direct problem. The inverse problem was solved using a two-step method. Nonlinearities of various types were considered. When introducing the computational grid, the generalized grid method was applied. A numerical method for solving the problem was proposed and implemented. The numerical results obtained illustrate how the problem is solved for speciﬁed experimental data.

Published: October 2024

Tool presentation: Polyhedra are a common set representation with widespread appli- cations in many areas of research, including convex geometry, reachability analysis, and invariant set computation. Their popularity stems from a tight relation to linear program- ming. Apart from some basic set operations with analytic formulae, the implementation of many polyhedral set operations in tools is not well documented. For this reason, we describe the evaluation of common set operations on polyhedra, including their runtime complexity, and provide an overview of their implementation as a dedicated class in the MATLAB tool Continuous Reachability Analyzer (CORA) for set-based computing. In particular, we highlight the handling of unbounded and degenerate sets. Finally, we com- pare our implementation to the popular multi-parametric toolbox.

Abstract
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the feed additive consisting of l‐arginine produced by fermentation with a genetically modified strain of Escherichia coli (CGMCC 7.401). The additive is intended to be used in feed and water for drinking for all animal species and categories. The genetic modifications introduced do not raise safety concerns. No viable cells or DNA of the production strain were detected in the final product. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the additive does not pose any safety concern with regard to the production strain. l‐Arginine produced with E. coli CGMCC 7.401 is safe for the target species when supplemented in appropriate amounts to the diet according to the nutritional needs of the target species. The FEEDAP Panel has concerns on the use of amino acids in water for drinking for hygienic reasons, and due to the risk of imbalances when administered simultaneously via feed and water. The use of l‐arginine produced with E. coli CGMCC 7.401 in animal nutrition is considered safe for the consumers and for the environment. The endotoxin activity of the additive does not represent a hazard for persons handling the additive. In the absence of data, the FEEDAP Panel cannot conclude on the potential of the additive to be irritant to skin and/or eyes, or to be a dermal or respiratory sensitiser. The additive l‐arginine produced with E. coli CGMCC 7.401 is regarded as an efficacious source of the essential amino acid l‐arginine for non‐ruminant species. For supplemental l‐arginine to be as efficacious in ruminants as in non‐ruminant species, it requires protection against degradation in the rumen.
ECOLOGICAL AND CENOTIC ROLE OF INVASIVE WOODY PLANTS IN FOREST-STEPPE ECOSYSTEMS
Authors: Lepeshkina L.
Published: October 2024

The paper examines the ecological and cenotic role of invasive woody plant species in forest-steppe ecosystems. The impact of discussed plants on the composition, structure, and ecology of these habitats was determined. Communities dominated by adventive trees and shrubs are characterized by low species richness – approximately 2-3 times less compared to background forest-steppe phytocenoses. Changes in the ecological parameters of oak forest and meadow-steppe communities were revealed. For the sloping limestone meadow steppe, there is an increase in the values of soil moisture (from 9.5 to 12.4), climate humidity (from 7.5 to 7.8), soil nitrogen content (from 4.6 to 6.3), illumination/shading (from 2.6 to 4.2); while indicators of climate continentality (from 9.4 to 8.6), soil acidity (from 8.8 to 7.4) and soil temperatures (from 8.8 to 8.5) decrease. For the sloping cretaceous forest-steppe, the following parameters increase: soil moisture (from 9.0 to 9.6), salt regime (from 6.8 to 7.3), soil nitrogen content (from 4.1 to 4.6) and illumination/shading (from 2.1 to 2.6) while there is a decrease in soil acidity (from 8.8 to 7.6). The ecological and cenotic strategy of invasive species in the region is aimed at transforming zonal and azonal ecosystem types with weakening and replacement of native ecosystem engineers. Ecotone anthropogenic habitats successfully occupy communities which were successfully colonized by communities of Acer negundo and Robinia pseudoacacia, blocking the development of zonal phytocenoses from Acer tataricum L. and Prunus spinosa L. The change in the ecology of rocky habitats leads to the transformation of the meadow steppe on limestone and the disappearance of populations of light-loving thermophilic calciferous-petrophytic plants. Protected areas are losing their ecological value as reference biosphere objects.
