Authors: OLATUNBOSUN DAPO , EBONG DICKSON , BANKOLE MAYOWA , ADEJOH FRANK , OBASI CHINEDU , OGUNROMBI TIJESUNI
Published: July 2023

This study investigates the thermal spatial expanse of green space and its cooling influence on the surrounding Land Surface Temperature (LST) of a densely urbanized area in Calabar Municipality, Nigeria using the Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) of Landsat 8 satellite remotely sensed data. Image pre-processing and analyses were implemented using the Environment for Visualizing Images (ENVI) and the Aeronautical Reconnaissance Coverage Geographic Information System (ArcGIS) application software respectively. Further statistical analysis using the Statistical Package for Social Sciences (SPSS) was performed. In addition, the Split Window temperature algorithm was applied to retrieve the LST. It was observed that Urban Green Space has a positive impact on the ambient environment. Statistical analysis reveals that there is a strong positive correlation between distance from the green space outer boundary and surrounding temperature, with a value of 0.935 at < 0.1 significance. This implies that as the distance increases from the green space outer boundary, the temperature difference increases progressively.

Authors: XUAN VU TRAM HUONG , THI LE; KIET HOAI , TRAN; HA TUAN , NGUYEN THI THU
Published: July 2023

Throughout history, heterosexuality created the main flow of society, and the entire social system took it as a standard. But recently a diverse perspective on sexuality has emerged. Thus, the topic of ‘queer’ and the violence of heteronormativity which are implicit in culture is concerned. This study will analyze the attitude of the mother about her lesbian daughter in the Korean novel “About my daughter” (2017) by Kim Hye Jin to understand if her attitude is deeply rooted in heterosexuality.
Musical Meaning and the Semiotic Hierarchy: Towards a Cognitive Semiotics of Music
Authors: Giacosa Gabriele
Published: July 2023

Research on the meaning of music has a long tradition, with approaches from several fields, but it lacks a coherent framework for interdisciplinary discussions. As a result, the notion of meaning in music is fragmented among contrasting perspectives. I propose a cognitive-semiotic approach to the analysis of the meaning evoked by music listening, adopting a framework that eludes disciplinary limitations and expands the notion of meaning to the phenomenological concept of intentionality. For this purpose, I apply Zlatev’s Semiotic Hierarchy to the experience of listening to music, analysing the diversity of meaning-making processes involved in music as distributed among several layers of experience. As a result, I propose an updated version of the Semiotic Hierarchy, clarifying its structure as based on possibilities of meaning-making, and allowing for temporality to pervade experience throughout all layers. I highlight the connectedness and simultaneity of different kinds of intentionality, resulting in the addition of the dimension of aesthetic experience – which I analyze as characterizing culture-general music listening. A key claim is that experiencing music aesthetically articulates the listener’s body in their inner sense of space and time, making them feel a sense of movement and vitality. This grounds music as a semiotic system, connecting with and fostering virtually uncountable subject-relative and culture-specific meaning-making acts.
The Language of Defining Synonyms in LDOCE and OALD between Consistency and Contradiction: A Source of Help or Confusion?
Authors: Abushaaban Hussein , Alhasan Rashad Faleh , Amar Khatra
Published: July 2023

This paper examines the language of definition in explaining a set of synonyms in two dictionaries: LDOCE and OALD. The selected set of synonyms is: ‘shake, tremble, quiver, and shiver’. The procedure of analysis was to decompose the definitions and the examples into meaning conditions and compare them to each other. The results suggested that the dictionary language that was adopted in both dictionaries followed a contradictory style of defining in terms of using restrictive and non-restrictive elements in the language of defining. This result suggests immediate revision in order to enable language learners to make better use of these dictionaries in terms of synonym comprehension.

Authors: Shaibu Ojoka Benjamin , Osisanya O Wasiu , Saleh Saleh .A. , Asarhasa E. Peter , Okpala Emeka Caleb
Published: July 2023

Granitic Gneiss and Banded Gneiss make up the bulk of the local rock types, and quartz veins are the most common intrusions seen there. Tectonic upheavals in the earth's crust are responsible for the region's structural features, including as foliations, folds, joints, and fissures. The goal of this research is to integrate several scientific techniques to subsurface structure definition. For this study, 16 Vertical Electrical Sounding (VES), petrophysical study, and background knowledge of geology were used to delineate subsurface rock. The Schlumberger array with a maximum electrode separation of 300m was employed for VES. Elete's true aquifer resistivity map shows that the South-Eastern and North-Eastern axis has relatively low resistivity values, which may indicate the presence of an aquiferous zone, while the North-Central and Southern regions have a wider range of resistivity values, which may not be consistent with a water-bearing zone. Additionally, petrographic analysis of the rock reveals that the mineral composition of Granitic Gneiss is Quartz (41.72%), Plagioclase (10.79%), Biotite (25.17%), Muscovite (19.42%), and Opaque (2.87%). While biotite makes up the granite gneiss. Biotite (45%), Muscovite (9.93%), Quartz (36.87%), Plagioclase (4.26%), and Opaque (3. 55%).Hydrogeologically, it stands to reason that Elete and its surroundings are situated in a region with medium to good groundwater potential based on the information at hand and the results of the geophysical investigation. Weathered/fractured basements are anticipated to contain productive aquifers.

Analysis of Polarity and Modality in Former President Olusegun Obasanjo’s Open Letters: A Critical Discourse Approach
Authors: Agwu Florence Nne , Amadi Gabriel Ndamzi
Published: July 2023

This study is an analysis of the deployment of polarity and modality in the open letters of former president Olusegun Obasanjo. The study examines how Obasanjo has used language to construct meaning and convey his perspective on the goings-on in the Nigerian society. The study captures various scholarly works in the area of critical discourse analysis, which is the theoretical framework of the research and further incorporates this theory into the analysis of the data. Data analysis focuses on the assessment and evaluation of the writer’s deployment of polarity and modality in his narrative, and it thus revealed that the writer has dexterously used polarity to assume a position of neutrality, without tilting more or less to either the negative or positive; it has also revealed that the writer’s deployment of modality has helped him express his core concerns, expectations and objectives for a better Nigeria, through the use of certain modal verbs. The study further recommends that future studies should harness other areas of critical linguistics, such as transitivity, mood and intertextuality to help construe the ideational motivations of the writer.
Critical Discourse Analysis: Narratives of Gender-Based Violence Victims in Bamenda-Cameroon
Authors: Fomukong Seino Evangeline Agwa , Yvette Tengen Bennaka
Published: July 2023

Gendered roles ascribed to members of society form the basis for their acceptance or rejection in that society. Whether subtle or overt violence, the effects are far-reaching and traumatizing on the victims, be they women, men, or children. This is obvious in discourses revealed in narratives of the violated. The questions asked are; how do the violated express themselves? What are the causes and effects of Gender-Based Violence (GBV) and how can it be curbed in society? Since language is a powerful instrument used in communicating feelings and thoughts especially, the language used in narratives surrounding domestic abuse forms the data for this paper. Data was collected from 29 participants between the ages of 25 and 50, using ethnographic approaches, particularly semi-structured interviews and focus group discussions. The theoretical bases were Fairclough’s Three-Dimensional Model which dwells on Description, Interpretation, and Explanation and Halliday’s Systemic Functional Linguistics with a focus on the ideational and interpersonal metafunctions. The analysis revealed that illiteracy, ignorance, dependency and poverty as some of the causes of GBV. Additionally, the analysis revealed that language patterns in transitivity are used by the victims in their struggle to maintain emotional balance and fight the existing cultural and societal stereotypes concerning how gender and sexuality affect their mental health. This paper, therefore, recommends the creation of safe spaces to enable victims of domestic violence to express their trauma and find healing in the process of narration.
The Arab Woman in Confrontation with The Forbidden Trinity
Authors: Hishmeh Lina Sh.
Published: July 2023

The oppressive reality of the Arab woman has undoubtedly made Arab feminist literature its own features. The woman's search for freedom is undoubtedly more able to express her injustice and oppression than the man because she suffers most from tyranny and oppression. Thus, feminist literature is the best experience for the woman to extract her rights, restore her deprived freedom through writing, raise her voice and exercise the freedom of expression that she has been deprived of for so long. She took out her pen and started "talking like Shahrazad", reveʿAling with her tongue her experiences and desires, and expressing her concerns and pains. In recent years, she is no longer writing to defend what has been stolen from her demanding change and freedom. Writing for her is no longer a defensive device, but an offensive system in which she condemns and retʿAliates against the man. In her revolutionary feminist narrative, she demonstrated her offensive tendency against all the taboos of the forbidden trinity: politics, religion, and sex, and demonstrated a clear challenge to social norms as well as the literary norms that were established by the masculine establishment. This study, therefore, shows how Arab women writers are able to break the forbidden pillars of the Forbidden Trinity by presenting each other's experiences and testimonies in their quest to challenge this oppressing trinity and to face its censorship powers.
Contemporary Northern Nigerian Literature and the Poverty Discourse: A Critique of Aliyu Kamal’s Hausa Boy
Authors: Abdullahi Nasir Umar
Published: July 2023

Literature plays numerous roles in the society: the cultural, the political, the religious, the economical, the social and the scientific (therapeutic). From the classical epochs to 21st century, writers have written and have been writing plays, poetry, novels, as well as short stories to educate, enlighten, persuade, warn and entertain their community, and sometimes the world at large. However, owing to the incessant changes in times, writers have to explore emerging themes such as migration, regional disputes, Aids, tribalism, terrorism, ethnic and religious violence, gender politics, institutionalized corruption and poverty for example. The aim of this paper is to explore the theme of poverty, as one of the contemporary thematic preoccupations in African literature in the 2I century, as portrayed in one of Aliyu Kamal‘s latest novellas, Hausa Boy. Set in the Northern part of Nigeria, Kamal ‘s prime concern is to demonstrate how some families in the country feel the deep and painful bite of abject poverty, which not only forces them to live from hand to mouth, but also makes it thorny for them to send their children to school. The end result is the children; particularly the young girls become street hawkers, a trade which endangers their life in the long run. The paper also wants to unveil that of the handful of the under-privileged children that have been to school, a significant number of them shamelessly drop out, owing to their parents’ inability to pay for their school fees. This further leads to the rising wave of the unemployment rate in the country. The paper reveals how poverty profoundly affects young men-women courtship, as it deters the former from fulfilling their cultural obligation of giving out some money token to their girl-friends and fiancées in each visit they pay to them as a sign of love. Yet, it is also a cultural practice, which causes the young men to suffer in Northern Nigeria’s contemporary reality.

Published: July 2023

El ácido elágico (AELG) es un metabolito en varias plantas y vegetales medicinales y se puede encontrar libre o como parte de la molécula más compleja (elagitaninos). Esta investigación tuvo como objetivo estudiar las interacciones de AELG y los aminoácidos (AA) en tejidos humanos. El software Hyperchem se utilizó como base para la química cuántica. Se tomó como base la teoría del coeficiente de transferencia de electrones (CTE). Los resultados arrojaron el AELG al fondo del pozo cuántico. Esta posición del AELG en el pozo cuántico se interpreta como una sustancia de acción prolongada. Los resultados de la caracterización por Resonancia Magnética Nuclear de H (H1-NMR) y C13 (C13-NMR) coinciden con la superposición cuántica HOMO y LUMO de la AELG. Se concluye que AELG es una sustancia oxidante de los AA, muy similar al agente quimioterápico ciclofosfamida.

Authors: Llushca Parra Lizeth Stefanía , Batallas Gómez Hernán Rodrigo
Published: July 2023

En Ecuador la sustanciación de los procesos judiciales se realiza a través de audiencias, con la participación de la autoridad judicial y las partes procesales, de tal forma que, la argumentación oral es fundamental para la exposición de los fundamentos jurídicos por parte de las defensas técnicas. Los argumentos posibilitan al abogado litigante sostener su postura o pretensión por medio de un razonamiento jurídico lógico, lo que se conoce como “la teoría del caso”, teniendo como objetivo llegar al convencimiento del juzgador sobre su tesis. La argumentación jurídica juega un rol importante en cada una de las etapas del proceso, es por ello que, los profesionales del derecho necesitan adquirir habilidades para fundamentar correctamente los elementos de hecho y de derecho por medio de la oratoria. El presente estudio analiza los nuevos paradigmas de la argumentación en las audiencias orales previstas en el Código Orgánico General de Procesos (2015), así como, los diferentes principios procesales y su conjetura con la argumentación jurídica, y aquellas nociones básicas que se deben conocer sobre el discurso argumentativo, mismas que las defensas técnicas emplean en los alegatos de apertura, práctica de la prueba y alegatos de clausura.

The results showed that the professionalism of employees in the General Planning and Budget Bureau of the Gorontalo Regional Police was not optimal. This can be seen from the 3 (three) indicators used as research benchmarks, only one indicator is considered fulfilled, namely the response indicator indicated by the speed of employees in providing services to line work units related to socialization requests, supervision and budget allocations. The other two indicators, namely the creativity indicator and the innovation indicator, are considered to have not been fulfilled, this is because some employees or personnel do not have the authority to carry out an innovation because they do not have the qualifications and competencies in their position so that so far the existing employees or personnel only work according to regulations. existing or in other words work normatively.
Neutrinos above the Earth's Surface
Authors: Belyakov Askold Sergeevich
Published: July 2023

In article “Doppler Effect and neutrino acoustic signatures”, published in the journal “LA MULTIAPP” on February 25, 2022, I was forced to touch on an astrophysical topic when, in the data stream obtained by monitoring the acoustic noise of the earth’s crust with high amplitude resolution (more 240 dB) and in a wide frequency band (from 0.1 Hz to 50 kHz) events began to appear, the forms and frequencies of which are not typical for geophysics and seismology. Similar forms can be seen in works on the detection of acoustic traces of neutrino decay in water and ice. The possibilities of increasing the sensitivity in measurements in a solid medium are discussed. In addition, underwater and underground facilities are being built that use the effect of Cherenkov radiation. All of these methods require complex and very expensive installations on a huge scale. Even acoustic measurements in water and in wells are very laborious and expensive, and most importantly: such measurements are forever tied to a specific place. Therefore, the creation of a light, compact and mobile device for recording acoustic traces of neutrino decay is an urgent task, the solution of which will allow recording traces of neutrino decay not only in water and the earth's crust, but also in air, into space, on planets and satellites.
Design Intelligent Protection System Based Microcontroller

Published: July 2023

Protecting vaccines and making sure they are still good until they are used is a problem that hurts people, especially in countries that don't have the right facilities to make sure vaccines are still good. This is because vaccines can lose their effectiveness if they are used in places other than where they were made. Whether you're putting something away or moving it, it's best to hold it back. In this project, we're going to build a system that will keep an eye on the COVID-19 vaccine and let people know if a vaccine isn't available because of a problem in the supply chain. The system has a microcontroller called the Arduino UNO, a temperature sensor, a GSM type SIM900, and a GPS device. The vaccine storage is measured by the temperature sensor. Messages are sent and received using GSM, which stands for "Global System for Mobile Communication." Satellites are used with GPS (globe position system) to find out where you are. If the temperature is too high (doesn't meet the criteria for storage), the system sends an SMS message with the location of the vaccine box (latitude and longitude). The location is being looked at on Google Maps.

Authors: Abdul Rahman Farhan Sabdin  , Che Haziqah Che Hussin  , Graygorry Brayone Ekal  , Arif Mandangan  , Jumat Sulaiman
Published: July 2023

In this study, we considered time-fractional nonlinear telegraph equations (TFNLTEs). For solving the TFNLTEs, we deployed a method known as the Multistep Modified Reduced Differential Transform Method (MMRDTM). Prior to the multistep technique, the nonlinear term in TFNLTEs is replaced with corresponding Adomian polynomials. It can be observed that the MMRDTM is much simpler and more straightforward. On top of that, it works exceptionally where the obtained solutions are more accurately approximated over time. To demonstrate the performance of the MMRDTM in terms of its capabilities and accuracies, we provided two numerical examples of solving TFNLTEs by using MMRDTM and Modified Reduced Differential Transform Method (MRDTM). By comparing the absolute errors of the obtained solutions by both methods, we demonstrated that the solutions provided by the MMRDTM much closer to the exact solutions compared to the corresponding solutions yielded by the MRDTM. This justified that the MMRDTM provides highly accurate and precise solutions for the TFNLTEs.

Batch adsorption of sodium ion (Na+) using Malaysian kaolin-based materials, zeolite A was studied and observed. The experiments were done at different parameters such as varying initial concentrations of sodium ions in seawater solution (70 to 280 mg L–1), pH range of 6 to 8 and various adsorbent dosages (0.1 to 0.4g). The Langmuir and Freundlich's isotherms were used to analyse the data, and the results were compared. This study discovered that the Langmuir isotherm matched the experimental data very well, with the maximum monolayer adsorption capacities derived from the Langmuir equation being 769.3 mg g–1. Using pseudo-first-order, pseudo-second order, and intraparticle diffusion models, the kinetics of the reaction were further investigated and understood. The Intra Particle Diffusion Kinetic Equation was the most accurate description of the adsorption kinetics of sodium ions onto zeolite synthesis.
Performance of Savonius Turbines with Tubercles Inspired by Humpback Whales
Authors: Sohib Abdelsattar  , Nurul Asyikin Abu Bakar  , Noorfazreena Mohammad Kamaruddin
Published: July 2023

Recent studies found that tubercles had been integrated into various applications beyond nature to enhance performance. Therefore, the present work investigates the performance of a Savonius turbine with various tubercle configurations at a wind speed of 7 m/s which corresponds to a Reynolds number of 148,000. The Savonius turbines with tubercle features were initially designed and inspired by the distribution of tubercles on the flippers of humpback whales. However, only the models with the best performance were chosen for fabrication and tested in the wind tunnel. The new turbine designs have 33% of the blade without tubercles, with turbine model 1 (D1) having a large tubercle beginning in the midspan and tapering towards the endplates, while turbine model 2 (D3) applies the 33% without tubercles in the midspan of the blade. The results demonstrated that turbine model 1 had the highest maximum Cp of 0.19 at the tip speed ratio of 0.78 and indicated that the spanwise location of tubercles in which it is integrated into the turbine is a significant geometric arrangement to improve the performance. The new turbine models designed with tubercles performed significantly better than the baseline model, with 46.15% and 23.08% improvements, respectively. The flow visualization for both models with tubercle configurations showed smaller wake sizes that represent reduced drag and eventually produced higher performance in comparison with the baseline. The results provide insights into the implementation of the tubercles concept on a Savonius turbine with a low aspect ratio.

Published: July 2023

Introduction. The paper presents the results of research on the influence of IR sources on the health of professionally and accidentally exposed personnel. Particular emphasis is placed on: identifying the relationships between the level of radiation dose and the development of oncological diseases; use of contemporary biological dosimetry methods for retrospective analysis of irradiation doses; the impact of parental irradiation on the health of the offspring; the structure of morbidity, including oncological diseases in patients exposed to IR sources.

Material and methods. The study material was used by subjects professionally and accidentally exposed to IR sources: medical staff and PMCCNA born in the Republic of Moldova, Ukraine and the Russian Federation, as well as their descendants, victims of the accident at the Fukushima Daiichi nuclear power plant (Japan) and residents of the region. Chelyabinsk. Clinical, immunological and cytogenetic methods were used.

Results. A wide range of mental pathologies was observed at PMCCNA, at the victims of the accident at the Fukushima Daiichi nuclear power plant, etc. The structure of immune deficiency syndromes was dominated by allergic and autoimmune syndromes. Based on the analysis of stable chromosomal aberrations, exposure doses were established.

Conclusions. In the absence of dose information received by staff professionally/accidentally exposed to IR sources, assessment of stable chromosomal aberrations makes it possible to reconstruct the radiation dose for PMCCNA exposed to low doses of IR.
The spectrum of liver presentation in wilson's disease: a literature review
Authors: TURCANU Adela , CUMPATA Veronica
Published: July 2023

Introduction. Wilson's disease represents one of the genetic diseases that has lifelong treatment, which significantly improved the quality of life for patients and reduced the disabling complications associated with the lack of an early diagnosis.

Material and methods. A structured search was performed in PubMed and HINARI, using English search terms: "Wilson's disease", "acute liver failure", "cirrhosis", "acute Wilsonian hepatitis", "hepatic manifestation", "chronic liver disease", "asymptomatic Wilson's disease", and "active chronic hepatitis".

Results. Wilson's disease can occur at any age and can mimic the presence of other chronic liver diseases. The hepatic expression is highly variable, ranging from asymptomatic presentation to severe liver diseases, such as decompensated cirrhosis and acute liver failure. Any patient with transaminitis and abnormal parameters of cooper metabolism should be comprehensively and carefully evaluated to identify Wilson's disease early and to prevent misdiagnosis or unnecessary therapies. Confirmation of the diagnosis should not exclude the co-existence of other liver diseases.

Conclusions. The use of validated and adapted scores for Wilson's disease may facilitate diagnosis, but they cannot be used in acute liver failure. Considering that WD presents itself with great phenotypic diversity and can evolve under the mask of other pathologies, it is necessary to carry out a careful differential diagnosis.

Introduction. The use of varenicline, an effective way to quit smoking, has become a subject of discussion in the mainstream media, social media, and the internet due to the growing number of people trying to quit smoking. YouTube videos serve a significant purpose in the drive towards smoking cessation with the aid of the drug mentioned above. This study aimed to evaluate the content of videos related to varenicline on YouTube.

Material and methods. Six different research terms were created for a search on YouTube. Two reviewers evaluated the videos for quality, reliability, and usefulness. After detecting useful and misleading videos, the factors affecting them as video parameters in these groups were compared.

Results. Of the videos evaluated, 78% were classified as useful, while the remaining 22% were misleading. Video length, number of likes and the likes ratio showed no significant difference between these two groups (p=0.264; p=0.075; p=0.798). The DISCERN (DS) and Global Quality Scale (GQS) scores of misleading videos were significantly lower (p=0.001). The DS and GQS scores of the useful videos were 2.58±1.11 and 2.67±1.05, respectively.

Conclusions. Misleading videos had a higher number of views and comments compared to useful videos. It was observed that independent YouTube users and media sources are producing more misleading videos. It is very concerning that cigarette quitters do not develop awareness in decision making about the misleading information from media and independent users. In contrast, health pages, physicians, and patient experiences can guide those trying to stop smoking.

Introduction. Mortality among tuberculosis patients, both nationally and globally, has decreased significantly in the last 10 years, but the current epidemiological situation in tuberculosis allows to predict a new rise in the endemic state of the disease due to the increase of TB/HIV coinfection and the resistant tuberculosis. 

Material and methods. The patient’s reports were analyzed – new cases, deaths due to the progression of tuberculosis registered in the Municipal Clinical Hospital of Phthisiopneumology, Chisinau, in 2 periods: the 1st period – 2001-2003 and the 2nd period – 2018-2020. During both periods, 64 new cases died in the hospital due to the progression of tuberculosis. Statistical data processing was performed with the application of the Student (t) test, the data were considered statistically true when p<0.05.

Results. In the first period, the age between 25-54 years (81.3%) predominated, in the second period between 45-65+ (73.5%) years of the deceased patients. In both periods, a high share of unemployed patients was found. In the 2nd period compared to the 1st period a severe form of disseminated tuberculosis was established – generalized tuberculosis that was not registered in the first period, the number of deaths with TB/HIV increased 6 times, 4.5 times – with stomach resection in anamnesis, 2 times – with diabetes, 1.5 times with chronic alcoholism. Primary multidrug-resistant tuberculosis was confirmed at 21.9%, extensively resistant tuberculosis – at 4.7% of deceased patients.

Conclusions. In the second period, the majority of the patients new cases due to the progression of tuberculosis died of severe forms of tuberculosis – generalized, increased number of comorbidities (mainly HIV infection), the presence of a large number of cases with primary resistant tuberculosis.

Introduction. For the first time, in the Republic of Moldova, there was established the seroprevalence of viral hepatitis B, C and E markers in patients with tuberculosis depending on gender, age and geographical areas.

Material and methods. 200 blood samples were collected from patients with tuberculosis and tested by the immuno-fermentative method for presence of viral hepatitis B, C and E markers.

Results. Following the investigations, it was established that the seroprevalence of the anti-HEV Ig marker in patients with tuberculosis is 12.0±2.3%. The seroprevalence of viral hepatitis B marker HBsAg in patients with tuberculosis was 13.5±2.4%, and that of viral hepatitis C anti-HCV – 9.0±2.0%. The study of investigations results for the presence of nominated markers depending on the geographical areas showed a significant statistically difference in the seroprevalence of the anti-HEV IgG marker in TB patients in the Central area of the country compared to the Southern area(p<0.05).

Conclusions. Patients with tuberculosis have a higher risk of developing viral hepatitis B, C and E, mainly affecting people aged 40-49 and > 60 years, including males.

Introduction. Intrasectoral collaboration in public health represents a huge potential for optimizing the three fundamental public health actions: disease prevention, health protection and healthcare awareness. The COVID-19 pandemic has significantly impacted the engagement of the parties particularly interested in disease prevention and control.

Material and methods. A mixed qualitative and quantitative research (in-depth interviews/questionnaire survey) was carried out within this paper.

Results. Most of the respondents assessed the intrasectoral cooperation as unsatisfactory and consider that the latest reform of the Public Health Service had a negative impact on it.  The pandemic alert caused by the COVID-19 infection served as a catalyst to improve cooperation. The main barriers to collaboration are considered the lack of staff and insufficient communication, various viewpoints and lack of public health knowledge, an overlying complex legal framework and lack of motivation, which often requires central authority involvement.

Conclusions. Some barriers to cooperation can be overcome without any systemic changes and centralized involvement, while more easily achievable measures such as joint training are sufficient. Thus, understanding these aspects can greatly improve the interaction between services.

Introduction. The evaluation of microbial biodiversity is an important step in the process of its conservation, and the identification of bacterial strains of biotechnological interest allows their application as support for the development of sustainable agriculture technologies.

Material and methods. From the lakes of the "La Izvor" park, 213 types of bacteria, 148 of them pathogenic, were isolated. From the non-pathogenic ones, those of biotechnological interest were determined the enzymatic properties, antimicrobial activity and were identified by molecular biological methods after that preserved by the lyophilization method with the determination of viability before and after lyophilization.

Results. The microbial biodiversity of the "La Izvor" lakes was studied, 213 types of bacterial colonies were isolated in pure culture, which of 148 proved to be enteropathogenic belonging to the genera Escherichia, Salmonella, Shigella, Enterobacter and Klebsiella as and other strains from the Enterobacteriaceae family. The purpose of the research consisted in the isolation and identification of non-pathogenic bacteria of biotechnological interest with different properties that could serve to elaborate and improve the development of sustainable agriculture technologies. Nineteen strains with enzymatic properties and high antifungal activity against phytopathogenic fungi, were selected for molecular identification, passported, submitted to the NCNM and preserved by the lyophilization method for determination valuable properties for a long time.

Conclusions. In the lakes of "La Izvor" park there is a very large variety of microorganisms, especially bacteria, some of which are enteropathogenic bacteria that can cause diseases in the population. Selected non-pathogenic strains stored in the NCNM can be applied against phytopathogens that cause dangerous disease and damage in agriculture major crops. As a result of lyophilization, we found that all strains showed the osmotic and thermal shocks tolerance and have a viability over 75%.

Key words: microbial biodiversity, isolation, identification, conservation.

Amines—organic molecules carrying the –NH2 moiety—have been recognized as a vital intermediate in the formation of prebiotic molecules such as amino acids and nucleobases. Here we report the formation of vinylamine (C2H3NH2), which was recently detected toward G+0.693–0.027, in interstellar ice analogs composed of acetylene (C2H2) and ammonia (NH3) exposed to energetic electrons. Our experiments mimic cascades of secondary electrons in the tracks of galactic cosmic rays impinging on interstellar ice in molecular clouds. Tunable photoionization reflectron time-of-flight mass spectrometry (PI–Re-TOF–MS), along with isomer-specific assignments, reveals the production of vinylamine (C2H3NH2). Quantum chemical computations suggest that both a radical–radical recombination of the amino (NH2) with the vinyl (C2H3) radical and a one-step concerted route are feasible pathways to vinylamine (C2H3NH2). The results present the first documented route to form vinylamine in interstellar ice analogs. This unsaturated amine, which is isovalent to vinylalcohol (C2H3OH), could be a key precursor for the abiotic synthesis of prebiotic molecules such as amino acids and nucleobases, with implications for the origins-of-life theme.
