Registered nurses improving screening rates for non AIDS related comorbidities in people living with HIV
Authors: Biggs Karen , Power Melissa
Published: June 2024

Objective: To establish whether a nurse-led screening and brief intervention project could improve screening rates for non-AIDS comorbidities in people living with Human Immunodeficiency Virus (HIV).
Design: A pre-post quantitative audit was used to evaluate the intervention of nurse-led comorbidities screening.
Setting: A publicly-funded, metropolitan, outpatient sexual health service in Western Sydney, New South Wales, Australia.
Subjects: One hundred medical records of people living with HIV were reviewed in each of the pre and post audits.
Interventions: A standardised co-morbidities screening tool was developed; education sessions were conducted with the registered nurses (RNs) and written and electronic resources were used as an adjunct in screening and educating clients.
Main outcome measure: To determine if interventions, including development of a structured screening tool and education with the RNs, would improve rates of nurse-led co-morbidities screening in people with HIV attending the service.
Results: All of the co-morbidities screening done in year two was initiated by the sexual health RNs, rather than the medical officers. Improved rates of screening were noted in 20 of the 22 audited items, with 13 of these showing a statistically significant increase in the one year time period from audit one to audit two. Potential and existing comorbidities were identified and managed according to local protocols.
Conclusion: RN led comorbidities screening for people with HIV can improve rates of screening in this client group. The screening tool has now become part of nurse led standardised annual care for clients with HIV.
Advanced skills for enrolled nurses: a developing classification
Authors: Cusack Lynette , Smith Morgan , Cummins Bernadette , Kennewell Louise , Dennett Lydia , Pratt Debra
Published: June 2024

Objective: This paper is a report of a literature review designed to identify strategies central to the implementation of the industrial classification of enrolled nurses (second level nurse) with advanced skills within Australia.
Setting: Australian healthcare and aged care organisations that employ enrolled nurses.
Primary Argument: Designing a clearly defined enrolled nurse with advanced skills role within an industrial classification, requires incorporation of advanced competencies, scope of practice articulation and specifically targeted organisational policies and procedures. These three areas are fundamental to successful role implementation.
Conclusion: There is limited discussion in the literature on strategies to ensure effective implementation of the enrolled nurse with advanced skills role. In addition, minimal research has been reported on the effectiveness of these roles in enhancing patient care and increasing workforce flexibility and efficiency. Further research and evaluation of the enrolled nurse with advanced skills is urgently required.
Literature review: “Are you ok there?” The socialisation of student and graduate nurses: do we have it right?
Authors: Goodare Pete
Published: June 2024

Objective: To determine the effectiveness of the current socialisation processes for student and graduate nurses, into the clinical practice setting.
Setting: The clinical nursing environment, with underlying links and reference to the academic setting of nurse education.
Subjects: The sole focal subjects of this literature review are student/undergraduate and graduate/new nurses.
Primary argument: Internationally, attrition rates of new graduate nurses in their first year of practice ranges between 30-60%. Undergraduate and new nurses enter the nursing profession with a beginning skill set, reflective of their education, coupled with preceded values and ideas about the profession itself. Recognition of an adjustment period undergraduate and new nurses require, is paramount to meeting the anticipated socialisation of these new professionals. Socialisation in the profession of nursing is an ongoing and complex interactive process by which the professional role, incorporating skills, knowledge, and behaviours, is learned and the individual consciously andsubconsciously seeks their sense of occupational identity, and perfecting this process is crucial.
Conclusion: Newcomers to the nursing profession have expressed that learning how to behave appropriately in the workplace is more difficult than bridging the gap between theory and practice. Intentional measures implemented by organisations, is paramount in enabling newcomers to adjust to the workplace, and it is unsafe to assume the process of socialisation is good, and underestimation of this socialisation process, would be negligent.

Authors: Ameri Malihe , Safavibayatneed Zahra , Kavousi Amir
Published: June 2024

Objective: The purpose of this study was to evaluate the intensity and frequency of moral distress and determine clinical situations leading to moral distress in oncology units. The study also examined the relationship between moral distress scores and demographic characteristics of oncology nurses.
Design: This descriptive study was performed between 25 January 2012 and 29 June 2013.
Setting: The study was conducted in the oncology units of eight training hospitals in Tehran, Iran.
Subjects: One hundred and forty eight nurses (131 females, 17 males; mean age 32.5 years; range 24 to 52 years) who had worked in oncology units of training hospitals in Tehran were included in the study.
Main outcome measure(s): The main outcome measures included intensity and frequency of moral distress, which were assessed by the Moral Distress Scale – Revised (MDS-R).
Results: Most of the 148 nurses had high to moderate scores. Nurses had experienced higher moral distress when receiving informed consent forms from patients and asking patients to carry out physicians’ order for unnecessary tests in patients’ last stages of life.
Conclusion: Moral distress exists in oncology nurses and interventions will be developed and tested to decrease and prevent it.
The art of clinical supervision: its development and descriptive mixed method review
Authors: Russell Kylie , Alliex Selma , Gluyas Heather
Published: June 2024

Objectives: The Health Workforce Australia Clinical Supervision Support Program Discussion Paper (2010) highlighted the education deficits of health professionals responsible for the clinical supervision of students. This research aimed to develop, implement and evaluate a new education program for nurses to assist in the development of knowledge and attitude to supervise students whilst on clinical practicum.
Design: The impact of the ACS program was determined using a descriptive methodology involving the collection and analysis of quantitative and qualitative data using a triangulation approach. This included the use of surveys, online reflections and interviews.
Settings: The ACS program was presented in both the metropolitan and regional areas of Western Australia.
Subjects: Participants (n=199) were from both the public and private health care sector working in a variety of nursing specialties within both the inpatient and community setting.
Results: Analysis of the data determined that participants improved their knowledge and attitude towards students and clinical supervision.
Conclusions: The ACS was confirmed as a strategy for providing effective education for nurses.
The role of advance care planning in end-of-life care for residents of aged care facilities
Authors: Waird Allyson , Crisp Elaine
Published: June 2024

Objective: This report will present the case of an elderly woman with rapidly declining health admitted to hospital from a nursing home. It will discuss benefits of advance care planning for residents of aged care facilities who have expressed opinions/wishes regarding their end-of-life care, and identify barriers, varying legal status, the need for documentation of discussion outcomes specifying residents’ wishes, and the importance of education and expert support for nursing staff.
Setting: Nursing home and acute tertiary referral hospital.
Subject: Female resident of a nursing home, aged 97 years, with acute onset of abdominal pain and multiple co-morbidities.
Primary Argument: The majority of nursing home residents do not have advance care planning initiated, nor is this routinely raised by nursing staff. While wishes may be discussed with family, they may not be fully respected if undocumented. Acutely ill residents are frequently hospitalised, especially when death is imminent, and often die alone in unfamiliar surroundings, tended by strangers. Many of these admissions could be avoided with Advance Care Planning, as could the resultant medical interventions which may cause the resident acute pain and discomfort.
Conclusion: Advance Care Planning can lead to avoidance of non-essential hospital transfers and their inherent risks and is likely to facilitate a dignified, peaceful death in familiar surroundings for nursing home residents, averting medical interventions which may cause needless pain and prolonged suffering.
A nurses’ guide to mixed methods research
Authors: Ingham-Broomfield Rebecca (Becky)
Published: June 2024

Objective: This article provides a breakdown of the components of mixed methods research methodology. The intention of the article is to simplify the terminology and process of mixed methods research to enable novice readers of research to have a better understanding of the language and concepts involved. The Survey method, using both qualitative and quantitative research methods, will be used to explain the principles of mixing methods.
Primary Argument: Australian nurses work in an environment where evidence-based practice is mandatory. Understanding the research process and terminology used may benefit nurses to implement research in their day-to-day practice. Gaining knowledge of the different approaches used in mixed methods research is paramount if nurses are to base their care on research which has utilised this style.
Conclusion: As mixed methods are used in nursing, social and behavioural research it is essential that nurses understand the methodology. The main components of mixed methodology will, therefore, be discussed in a systematic, logical order.
What prompts nurses to seek help from wound care consultants in spinal cord injury management?
Authors: Bundz Julie , Schuurs Sarita , Kendall Melissa , Amsters Delena
Published: June 2024

Objective: This study aimed to identify clinical scenarios that might prompt nurses to seek advice from a spinal cord injury wound care nurse consultant for pressure injury management. In addition, some attributes of nurses were examined for associations with intention to seek the help of a consultant.
Design: Exploratory quantitative survey.
Setting: Queensland, Australia.
Subjects: Fifty currently practising hospital and community based nurses.
Main outcome measure(s): Two part online survey - part one presented hypothetical clinical case scenarios, in which respondents indicated their likelihood of seeking help; and, part two examined participant attributes and work experience.
Results: Each scenario presented was rated as either of little importance or utmost importance by at least one respondent. Participants identified consultant personality and proximity as more influential on help seeking than timeliness, common sense or knowledge.
Conclusion: The study did not identify a pattern of association between the presence of certain clinical factors and intention to seek help from a spinal cord injury consultant nurse for pressure injury management. What is important and influential for one person may be of less importance for others. Consultants must market their value to nurses in order that they are front of mind during the help seeking process. Further studies are required to examine the decision making process associated with help seeking.
The Cancer Nurse Coordinator Service in Western Australia: perspectives of specialist cancer nurse coordinators
Authors: Monterosso Leanne , Platt Violet , Krishnasamy Meinir , Yates Patsy , Bulsara Caroline
Published: June 2024

Objective: In Western Australia the cancer nurse coordinator (CNC) role is unique, state wide and situated in nursing. It requires the domains of clinical expert, resource consultant, educator, change agent, researcher and advocate to facilitate seamless coordination of care for patients across metropolitan, rural and remote geographical areas of Western Australia. This study examined the role, function and impact of CNCs from the perspective of coordinators themselves.
Design: Prospective two-phase mixed method study. This paper reports data from the Self Report Activity Questionnaire in Phase one.
Setting: The state-wide Western Australian Cancer Nurse Coordinator Service.
Subjects: Metropolitan and rural CNCs (n=18) who had worked in the role for at least six months.
Results: Overall, CNCs spent 70% of time in clinical consultation and 41% of CNCs reported having an educational role. Most CNCs (71%) noted that at least half of their patients had complex psychosocial needs at referral. Key role-related activities related to direct nursing care and patient education were performed most frequently on a daily basis. Tasks related to care management planning, patient advocacy and multidisciplinary clinical care were performed weekly. Strategic, team communication and professional development activities were performed less frequently.
Conclusion: Diversity of the CNC role was demonstrated with findings showing that CNCs fulfilled the core components of the specialist cancer nurse. Given the clear need to provide consistent support to cancer patients in an increasingly individualised and integrated manner, we consider the CNC role a fundamental element of quality cancer care.
Accessibility and outcomes from a rural diabetes nurse-educator led self-management program
Authors: Roberts Diane , Ward Bernadette , Russell Deborah , O'Sullivan Belinda
Published: June 2024

Objective: To investigate factors associated with access to, and health outcomes of, a diabetes nurse-educator led self-management program for rural Australians with diabetes.
Design: Retrospective cohort study.
Setting: A rural community-health service with a dispersed catchment of 10,000 population.
Subjects: Clients diagnosed with type 2 diabetes mellitus and referred to the program between April 2008 and December 2012.
Intervention: A diabetes self-management program comprising an initial assessment, a group education session, and 3, 6, and 12 month clinical reviews.
Main outcome measures: Program attendance after referral; and achievement of management goals for HbA1c, BMI, total cholesterol, quality of life and psychological distress.
Results: Ninety-four percent (n=219/232) of referred clients attended at least once. Multivariate logistic regression showed that attending at least once was significantly associated with living within 25km of the service. Non-smokers/former smokers, general practitioner-referred clients and those with diabetes management plans were significantly more likely to attend three or more sessions. At 12 months clients showed significant improvements in cholesterol, BMI, quality of life and psychological distress.
Conclusion: This study demonstrates that diabetes nurse-educator led self-management programs which adapt to their rural contexts – including geographically dispersed catchment populations and resource constraints – provide highly accessible services meeting the needs of most. Nevertheless, some groups (cigarette smokers, those living furthest from the service) may remain marginalised and less able to access services. Improvements in health outcomes for these clients may require further adaptation of models of care to better target their health care needs.
Managing medical service delivery gaps in a socially disadvantaged rural community: a Nurse Practitioner led clinic
Authors: Kelly Jo , Garvey Deb , Biro Mary Anne , Lee Susan
Published: June 2024

Objective: The aim of this pilot project was to investigate how Nurse Practitioners (NP) manage medical service delivery gaps in a socio-disadvantaged rural Victorian region.
Design: A cross-sectional study utilising data from patient consultations that took place at the Nurse Practitioner Community Clinic (NPCC) over six months in 2013 and patient satisfaction survey.
Setting: The NPCC is a rural clinic servicing a rural population in Victoria.
Subjects: 629 patients.
Main outcome measures: Numbers of patients; presentations; age; gender; postcode; reason for encounter; consultation length; availability of General Practitioner (GP); consultation activities and follow up; NP Medicare Benefits Scheme (MBS) item number rebate; and equivalent GP MBS item number rebates.
Results: Over 50% of patients were female; 60% aged over 45 years. Patients had 2.6 encounters with the NPCC; over 50% lasting between 10 and 20 minutes. Approximately half the revenue of that claimed in equivalent GP encounters. Common reasons for attendance were symptoms and complaints (37.2%) and attendance was viewed as convenient and accessible, despite having a regular GP (47.8%). Fifty-six Patients responded to a satisfaction survey and indicated they were satisfied with the service would use the service again and would recommend it.
Conclusions: The NPCC provided an accessible service that met patients’ needs in a rural community. The study provides evidence that NPs can provide medical management in areas where medical service delivery gaps exist. However, there was a significant discrepancy between funding reimbursements for services provided at the NPCC and those provided by GPs.

Authors: Carvalho Soccal Daiana , Mombaque dos Santos Wendel , Marli Matiko Anraku de Campos Marli
Published: June 2024

Objective: To evaluate the potential drug interactions in patients with acute lymphoblastic leukaemia in the remission induction period of treatment.
Design: A prospective cohort study.
Setting: A tertiary referral centre.
Subjects: Twenty-two children undergoing treatment for acute lymphoblastic leukaemia. The median age was 4.5 years (minimum of 1 and maximum of 18 years) with male predominance (54.4%).
Main outcome measure: Presence of potential drug interactions in patients undergoing treatment for precursor cell lymphoblastic  leukaemialymphoma. The potential drug interactions term refers to the ability of a drug to affect the pharmacologic intensityas well as the therapeutic effect of another and cause adverse reactions, as well as the possibility of clinical manifestations.
Results: All participants were exposed to at least one potential drug interaction. About 60% of interactions classified as more severe. Every new drug included in the treatment increased the chance of potential drug-drug interactions by 0.4 times.
Conclusion: These results demonstrated the patients under chemotherapeutic care for lymphoblastic leukaemia-lymphoma have high potential for drug interactions of greater severity.
Long term effects of child abuse: lessons for Australian paediatric nurses
Authors: James Felicity , Green Janet
Published: June 2024

Objective: Child abuse has short and long term consequences. Literature that explores the long term effect of child abuse on children has been reviewed.
Setting: Prevalence of the long term consequences of child abuse within the Australian paediatric population.
Sample: The search utilised medical search terms of ‘child abuse’, ‘long term effects’, ‘adverse childhood events’, ‘violence’, ‘cortisol response to stress’, ‘post-traumatic stress disorder’, ‘nurs*’, ‘paediatric’, ‘abuse’, ‘neglect’ and ‘prevention’ in health related databases to locate literature published from 2007 until present.
Primary argument: Data concerning child abuse and neglect in Australian children is sparse and inconsistent with no literature found specifically relating to the role of paediatric nurses.
Conclusion: Further analysis on the effects of child abuse and neglect on Australian children will help to gauge its health burden on the country, and to help health professionals better understand this contemporary child safety concern.
Does studying postgraduate palliative care have an impact on student’s ability to effect change in practice?
Authors: Rawlings Deb , Devery Kim
Published: June 2024

Objective: To find out from alumni whether their postgraduate course in palliative care had an impact on their ability to change practice.
Setting: Palliative & Supportive Services, Flinders University has delivered postgraduate palliative care courses via the online learning mode of delivery since 2004.
Subjects: An online survey was administered to alumni asking about such issues as: the impact of learning for practice, and their ability to influence change (Flinders University ethics no: 7154). Seventy-six alumni responded to the survey, and were mostly older female nurses, which is not only a reflection of our student cohort but also of clinical practice.
Primary argument: In this study, we are examining the relevance of our courses to practice, specifically how alumni report the impact of postgraduate study on both their individual clinical practice and organisational systems. Evidence based practice is the cornerstone of nursing and of education programs globally and while our students are learning best practice they report that they cannot easily translate their new knowledge into practice.
Conclusion: Clinicians with postgraduate qualifications can be empowered to expand their clinical skills and more, for example, their leadership capabilities, to critically challenge health care systems and act as a role model for others. However, if we are to truly build the capacity of our students and alumni to implement changes in the workplace then we need to also engage them in evidence to practice strategies and change management theory and practice.
The care of older people with dementia in rural Australian hospitals – a case study
Authors: Shannon Kay , Cruickshank Mary , Grealish Laurie
Published: June 2024

Objective: Investigate how nurses in rural hospitals care for people with dementia.
Design: A case study research design.
Setting: Three rural hospitals in one region of the state of New South Wales, Australia.
Subjects: A purposive sample of 21 nurses who were employed at the study sites.
Main outcome measure: Description of how nurses working in rural hospitals care for people with dementia.
Results: Nurses drew upon their community connectedness to creatively use limited resources to provide person-centred care for people with dementia. The physical environment of the hospital influenced rural nurses’ practice, with chemical and physical restraint occasionally used when nurses’ were concerned about workload and safety.
Conclusion: Rural nurses used their community connectedness to help them provide person-centred care for people with dementia, but at times, this care was limited by overriding concerns about risk management and patient safety.
Preserving families psychological and psychosocial health in PICU: a review on the health professionals role
Authors: Johnston Teaghan
Published: June 2024

Objective: The aim of this review was to examine the health professional’s role in preserving the psychological andpsychosocial health of family units of paediatric intensive care patients, and to identify strategies used to reduce this risk long term.
Setting: Paediatric Intensive Care Units.
Subjects: Family units of paediatric intensive care unit patients.
Primary Argument: For the family of a child admitted to the paediatric intensive care setting, the psychological and psychosocial impacts are varied, and in many cases detrimental to the family unit itself. Health professionals, in particular nurses, perform a vital role in identifying the risks posed to these families.
Conclusion: The family unit becomes at great risk of poor psychological and psychosocial health when a child member is admitted to an intensive care unit. Nurses play a pivotal role in promoting and implementing strategies to reduce the negative impacts often experienced by these family units. Health professionals must have a thorough understanding of this risk, to be able to adequately screen and assist in preserving the health of these family units.
Side effects of chemotherapy in children with cancer: effects of nursing training administered to caregivers
Authors: Uzun Zeynep , Kucuk Sibel
Published: June 2024

Objective: The present study aimed to assess the consequences of providing nursing training to caregivers of children with cancer on the side effects associated with chemotherapy.
Design: The present study used a pre-test-post-test experimental design.
Setting: The study was conducted in a paediatric hematological oncology hospital in Ankara, Turkey.
Subjects: This study was conducted with 40 caregivers responsible for looking after child patients, all of which had been recently diagnosed with cancer, but who had not started chemotherapy.
Primary argument: The knowledge scores of the caregivers on issues related to infection and bleeding risk, nutrition and oral care and total scores were significantly higher than their pre-test scores before undergoing training (p<0.05).
Conclusion: Planned training on the problems that may arise due to the side effects of chemotherapy was found to be effective in increasing the knowledge level of caregivers. The authors suggest that training in this subject should be provided before initiating a chemotherapy program, before the occurrence of side effects, and visual and written materials should be used.
Harnessing autophagy: A potential breakthrough in digestive disease treatment
Authors: Esrefoglu Mukaddes
Published: June 2024

Autophagy, a conserved cellular degradation process, is crucial for various cellular processes such as immune responses, inflammation, metabolic and oxidative stress adaptation, cell proliferation, development, and tissue repair and remodeling. Dysregulation of autophagy is suspected in numerous diseases, including cancer, neurodegenerative diseases, digestive disorders, metabolic syndromes, and infectious and inflammatory diseases. If autophagy is disrupted, for example, this can have serious consequences and lead to chronic inflammation and tissue damage, as occurs in diseases such as Chron's disease and ulcerative colitis. On the other hand, the influence of autophagy on the development and progression of cancer is not clear. Autophagy can both suppress and promote the progression and metastasis of cancer at various stages. From inflammatory bowel diseases to gastrointestinal cancer, researchers are discovering the intricate role of autophagy in maintaining gut health and its potential as a therapeutic target. Researchers should carefully consider the nature and progression of diseases such as cancer when trying to determine whether inhibiting or stimulating autophagy is likely to be beneficial. Multidisciplinary approaches that combine cutting-edge research with clinical expertise are key to unlocking the full therapeutic potential of autophagy in digestive diseases.
Nitrosation of Lignosulfonates under Solid-Phase Catalysis Conditions
Authors:   Northern (Arctic) Federal University named after M.V. Lomonosov, Khabarov Yuriy G. , Veshnyakov Viacheslav A. , Plakhin Vadim A. , Skripnikov Evgeniy A. , Ovchinnikov Denis V.
Published: June 2024

Lignosulfonates are the most common commercial lignin-based product due to their unique properties. Various methods are known for modifying lignosulfonates and lignosulfonic acids. This article presents the results of the development of a new approach to the production of nitrosated lignosulfonic acids. The method is based on a reaction catalyzed by cation exchange resins in the H-form: KU-2-8 cation exchanger and wofatite. The influence of reagent consumption and reaction duration on the course of nitrosation has been studied. The dynamics of the proposed nitrosation practically coincides with the dynamics of a similar reaction using sulfuric acid by the known method. The optimal consumption of sodium nitrite equals 15 %, and the optimal consumption of cation exchanger equals 100 % by weight of lignosulfonates. During the nitrosation of lignosulfonates, significant changes in the electronic spectra occur in the region of 280...500 nm. Two overlapping absorption bands appear with maxima at 300 and 330 nm, as well as an intense absorption band at 430 nm, due to nitroso groups conjugated with the aromatic nuclei of phenylpropane units. To analyze the ionization spectra, they have been deconvoluted. The resulting spectra are well approximated by 5 Gaussians with an error of no more than 5 %. Two options for carrying out the nitrosation reaction of lignosulfonates have been proposed: under static and dynamic conditions. It has been established that under dynamic conditions, nitroso derivatives of lignosulfonic acids are formed that do not contain metal cations, and the pH of the resulting solutions does not exceed 1.4. The elemental compositions of the isolated initial and nitrosated lignosulfonic acids have been determined. The nitrogen content of lignosulfonic acids has increased from 0.32 (initial) to 2.17 % (nitrosated). In addition, under dynamic conditions, an additional stage of separating the cation exchanger from the reaction medium by filtration is not required. New bands have appeared in the IR spectrum of nitrosated lignosulfonic acids: at 1540 cm–1, which is due to the presence of nitroso groups, and a wide absorption band at 1700...1715 cm–1, which can be caused by vibrations of the carboxyl group or the quinone monooxime tautomeric form of the guaiacyl structures of lignosulfonic acids.
Dendroecological Research into Aspen Growth in the Conditions of the Moscow Region
Authors:   Bauman Moscow State Technical University (Mytishchi Branch), Rumyantsev Denis E. , Vorob’yeva Nataliya S.
Published: June 2024

According to V.A. Dragavtsev's concept, the reaction of the annual ring to the provocative environmental background of different years creates a “portrait” of adaptive polygenic genotype systems. By comparing the reactions of the main forest-forming species from an ecologically homogeneous habitat, it is possible to assess the level of similarity of their ecological properties. Cluster analysis of tree-ring chronologies of aspen and species growing together with it, correlation analysis of chronologies and indexed chronologies, as well as time series of meteorological factors and Fourier spectral analysis have been used for a dendroecological research into aspen growth features in the conditions of the Molokchinskiy Botanical and Entomological Reserve of the Sergiev Posad District of the Moscow Region. To compare with the chronologies of aspen from two stands, the chronologies of European white birch, English oak, grey alder and Norway spruce have been used. It has been established that the cluster analysis of indexed chronologies based on calculating the squared Euclidean distance and combining the chronologies into groups according to the rule of complete linkage distinguishes aspen chronologies into a separate cluster, very distant from the other species under consideration. According to the correlation analysis of indexed chronologies, the dynamics of radial increment of aspen is most closely related to the dynamics of radial increment of European white birch and gray alder. Moreover, the maximum correlation coefficient (0.71) is observed for the chronologies of aspen from two different stands. Among the climatic factors, the main limiting influence on aspen increment is exerted by July precipitation in the year of the annual ring formation and August precipitation in the year preceding the year of the annual ring formation. The response to precipitation in August last year is specific to aspen stands and has several options for ecophysiological interpretation. According to Fourier spectral analysis, aspen chronologies have the most pronounced cyclic component with a period of 10.4 years, which completely coincides with the cyclic component of the time series of Wolf numbers in the time interval under consideration. This distinguishes aspen from the rest of the studied forest-forming species. A conclusion has been made about the specificity of the dynamics of the radial growth of aspen in comparison with other forest-forming species under study.
Needle-Like Leaf Organs of Conifers. Part I. Modeling the Needle Cross-Section Perimeter
Authors:   https://orcid.org/0000-0003-2081-5090, Tarasov Natal’ya V. , Gerling Natal’ya V.
Published: June 2024

Despite the availability of measuring systems for estimating the surface area of leaf organs of higher plants, the need for simple standard methods for determining this indicator area remains relevant for plant physiologists. The methods for estimating the surface area of needle-like leaf organs of conifers, based on the geometry of an individual needle rest on the general principle of calculating the needle surface area as the product of its length by the perimeter of its cross-section. This makes the cross-section perimeter one of the most important parameters needed to characterize the needle surface area. The strong variability of this parameter depending on the species necessitates the development of individual models of the cross-section of individual needles. The aim of this study has been to create a universal model for estimating the needle cross-section perimeter, irrespective of the tree species. For the practical implementation of the aim, a method was proposed for estimating the perimeter of the needle cross-section, based on the well-known fact that any closed line is transformable into an equivalent circle, while the length of the closed line does not change. The perimeter of the equivalent circle can be related to the parameters of the geometric figure before the transformation. This approach allows us to relate the width and thickness of the needle cross-section to its perimeter. The developed universal model of the needle cross-section has been verified on cross-sections of Siberian fir (Abies sibirica L.) and common juniper (Juniperus communis L.) needles. The samples of needles of these woody plants have been collected from a bilberry-sphagnum spruce forest in the boreal zone of the north-east of the European part of Russia (Knyazhpogostkiy district, the Komi Republic). Statistical analysis has shown the significance and adequacy of the model. It can be used to assess the perimeter of coniferous needles, irrespective of their species. In this case, the accuracy of perimeter estimation is comparable to the accuracy of direct perimeter measurement by the piecewise linear approximation method.

Restoration of the pool of coarse woody debris after disturbances is one of the mechanisms for maintaining the stability of forest biogeocenoses. The studies of coarse woody debris have been carried out in the “Vepssky Forest” Reserve in the Leningrad Region on 8 sample plots established in primary forests (4 sample plots) and in secondary forests of the 1st generation after logging in 1973–1974 (4 sample plots), where the composition and structure of the stand, as well as the site conditions have been identical to those in primary forests. The coarse woody debris has been inventoried on transects. The stocks of coarse woody debris in primary stands have ranged from 104 to 233 m3 ha–1. Windfall and leaning trees have prevailed. The proportion of deadwood in both primary and secondary forests has been low. Clear cutting has significantly changed not only the stock of coarse woody debris, but also its distribution by decay classes and substrate categories. The stocks of coarse woody debris in secondary forests have ranged from 8 to 40 m3 ha–1, and have been mainly represented by stumps. The coarse woody debris of the 4th and 5th decay classes has almost been absent in primary forests, while in secondary forests the proportion of highly decomposed wood remaining after cutting has been about 50 %. The ratio of coarse woody debris and growing stocks has been on average 1:1 and 1:5 in the biogeocenoses of primary and secondary forests, respectively. The annual carbon balance of coarse woody debris (the difference in fluxes due to the loss of growing forest and the decay of coarse woody debris) has ranged from 0,40 to 2,80 t C ha–1 year–1, averaging 1,75 and 0,63 t C ha–1 year–1 in secondary and primary forests, respectively. The positive annual carbon balance in the coarse woody debris is due to the predominance of the rate of the loss of growing forest over the rate of the decay of coarse woody debris in primary forests as a result of wind disturbances and as a result of self-thinning of the stand in secondary forests.
Evaluation of the efficiency of reference machine learning models for buffer memory prediction when transforming a self-similar input stream of packets into a stream having exponential distribution under the condition of equality of mathematical expectations and median flows
Authors:   North Caucasus Federal University, Linets G. I. , Voronkin R. Al. ,   North Caucasus Federal University, Govorova S. Vl. ,   North Caucasus Federal University
Published: June 2024

Using machine learning methods, models have been developed to predict the size of the queue depending on the Hurst exponent based on the data obtained when performing the transformation of an input self-similar stream distributed according to the Pareto law into a stream having an exponential distribution with equal mathematical expectation and equal medians. A comparative analysis of the obtained models is carried out. Each model was examined using the following quality metrics: coefficient of determination, rms regression error, mean absolute error, penalty value, estimated loss. Models that use isotonic regression and support vector methods are the best in terms of the selected quality metrics for methods of transforming the input and output packet streams when the mathematical expectation is equal. For methods of transforming the input and output packet stream with equal medians, linear models are the best.
Cleaning images from impulse noise in a binary symmetrical channel
Authors:   Regional Scientific and Educational Mathematical Center ", Orazaev A. R. ,   North Caucasus Center for Mathematical Research
Published: June 2024

The paper proposes a new method for cleaning uncoded images from impulse noise in a binary symmetric channel, where, when an error occurs, the information bit is distorted and the image pixels take incorrect values. The characteristic of such noise cnuorresponds to impulse noise, where impulse noise takes on random values and is randomly distributed over the image. Pixels are determined to be distorted by evaluating the difference between pixels within the local window. This estimate takes into account the brightness value and the distance of pixels within the local window. Image recovery is performed using adaptive median filtering.

The article examines the multi-vector nature of modern Spanish foreign policy. The article considers the strategy of external actions in which the European vector is the key and is perceived by the Spanish government as a natural basis for its political and economic development. The North American and Latin American vector of foreign policy is presented. The change of power in the United States and Spain has demonstrated a steady progressive dynamics in Spanish-American relations. The designated vectors of foreign policy form a triad, but the influence of four more foreign policy choices is increasing: American, Mediterranean, Middle East, Asia-Pacific.

Interest in facial emotion recognition is increasing and new algorithms and methods are being introduced. Recent advances in supervised and unsupervised machine learning have led to breakthroughs in research, and more and more accurate systems are emerging every year. However, despite significant progress, emotion detection remains a very challenging task. Experimental studies of emotional processes are usually based on the observation of images with affective content, including facial expressions. This paper presents the implementation of an emotional expression classifier by training a face detection algorithm on a dataset of AKDEF frontal face images (N = 4,900). The trained convolutional The purpose of the study was to present normative data regarding the recognition of six facial expressions with emotional content as well as neutral facial expressions. using a forced-choice task. In this study, agreement in recognition between the expressions depicted and chosen by the participants ranged from 70% (for anger) to 76% (for happiness). Overall, the results show a high level of recognition of the facial expressions presented, suggesting that the AKDEF provides adequate stimuli for studies examining the recognition of facial expressions of emotion. Participant gender and age had limited impact on emotion recognition, but model gender and age require additional consideration.

At present, technologies and methodological aspects of managing groups of multirobotized systems intensively developed. The full application of decentralized groups of robots requires the solution of several classes of problems, one of which known as the distribution of tasks in a group of robots or the division of labor. Algorithms for the division of labor are diverse and based on a wide range of mathematical methods, many scientific works are devoted to this issue. To systematize the methods of task distribution, this paper analyzes and classifies the tasks to solve for group robotics. In the process of studying the literature on this issue, a pool of tasks obtained that solve certain methods. As a result of the literature review, it is proposed to introduce a classification of tasks based on the specifics of their implementation.

Milk casein has important properties that ensure the widespread use of this protein in industry and increased interest in its study by researchers. Studies of the structure of casein in its native state have revealed its micellar structure. The presence of large ions leads to an increase in the volume of micelles, while acidification results in a decrease. During storage, the ability of MCC to rehydrate and dissolve reduces, aggregation and degradation of the structure are observed, with an increase in storage temperature, these indicators noticeably decrease. Thermal stability is greatest near neutral pH. MCC has gel and foaming properties. In the presence of transglutaminase, the stability of micelles rises. In the same way, under the increased pressure – the coagulation time of micelles increases. The surface activity and hydrophilicity of micellar casein directly depend on the degree of aggregation of micelles, the lower it is, the higher the values of these indicators. The organoleptic characteristics of this additive are favorable. Due to the high content of protein and the peculiarities of its digestibility, MCC is actively used in the production of specialized nutrition, for example, dietary, sports, children's, etc. The process of producing yogurt, desserts, cheeses (processed and hard) is an aggregation of milk casein to varying degrees, the use of commercially available micellar casein makes it possible to make the production process more controlled and improves the quality of final products. In the meat processing industry, functional additives containing milk proteins and casein are actively used, however, there are no data on the introduction of micellar casein into functional mixtures as an individual component. A detailed analysis of the data regarding the physicochemical and technological properties of micellar casein concentrate, such as thermal stability, solubility, waterretaining and gelling abilities, surface-active properties, foaming and influence on the organoleptic properties of products, is given. The existing examples of its application in various fields of the food industry are considered: in the production of high-protein and lowcarbohydrate drinks, sports nutrition, yoghurts and desserts, hard and processed cheeses, as well as in meat processing.
