Fractional Chief Financial Officer (CFO), A Catalyst to SMEs Survival for Economic Growth
Authors: Okugbere Oghenevwire. F.
Published: February 2025

In every economy of the world, the part played by SMEs cannot be overemphasized. Name it, Africa, Asia, Europe, and America. This sector is the backbone of all economies and cannot be ignored. In the United States of America for example, every successive regime has included it in their manifesto and campaigned vigorously during every election. Ultimately, has made it a pivotal part for economic growth and development.

SMEs being the pillar of economic growth do not exist without their own challenges. Some of the key issues or challenges faced are Inflation, high interest rates, access to credit, hiring and employee retention and Supply chain disruptions are just a few of the challenges that give small business owners sleepless night.

The role of a fractional CFO (Chief Financial Officer) is becoming increasingly relevant to addressing these small and medium-sized enterprises (SMEs) challenges especially in the United States, particularly in stimulating economic growth and fostering resilience in the broader economy.

A fractional CFO provides high quality level financial leadership on a contract basis without the cost of hiring a full-time CFO. By offering strategic financial advice, financial modeling, cash flow management, and risk mitigation, a fractional CFO can act as a catalyst for SME survival and growth.

Fractional CFOs are highly skilled professionals with a blend of technical qualifications, strategic insight, and business experience. To effectively support an SME, fractional CFOs should have the right mix of education, certifications, industry experience, and soft skills to provide both day-to-day financial management and long-term strategic advice. Businesses looking to hire a fractional CFO should ensure they clearly define their needs, vet candidates for relevant experience, and set expectations for the engagement to ensure a successful partnership.

SMEs seeking to maximize financial strategy, boost profitability, and scale successfully, hiring a fractional CFO (Chief Financial Officer) can be a wise decision. To choose the best fractional CFO, nevertheless, one must carefully evaluate their credentials, experience, and certifications to be sure they can offer the required knowledge. A thorough reference to the essential credentials, licenses, and work history that companies should consider before hiring a fractional CFO can be found below.

Published: February 2025

Visually impaired individuals face challenges in moving safely, affecting their independence and increasing the risk of accidents. This work presents the development of a prototype accessory for canes with ultrasonic sensors, designed to enhance mobility and independence at a low cost. The device, based on IoT, uses an Arduino Nano, an HC-SR04 ultrasonic sensor, and a buzzer, generating progressive acoustic alerts based on obstacle proximity. During testing, it demonstrated high effectiveness in detecting large objects and issuing immediate alerts; however, it showed limitations with small objects, liquids, and humid environments. The need to optimize the battery, which is currently replaceable, was identified, and as a future improvement, the incorporation of wireless charging technologies and LIDAR sensors was proposed for more precise detection. Additionally, it was recommended to include a night LED to alert others and improve the cane's materials for greater durability. The prototype's design is lightweight, accessible, and functional, prioritizing simplicity without compromising reliability. Compared to similar devices, it stands out for its effectiveness and low cost, offering a viable solution to improve the mobility and independence of visually impaired individuals, reducing risks and facilitating social integration.

Portraying Competence, Benevolence, or Party Loyalty? Political Propaganda and the Image-Building of Political Elites in China
Authors: Yan Yang , Yang Zhusong
Published: February 2025

How do political elites in authoritarian regimes shape their public image? Drawing on a unique dataset covering official news releases of the daily public activities of all provincial party secretaries in China from 2016 to 2022, this study finds that authoritarian elites manipulate the propaganda apparatus to project various public images. Text analysis shows that provincial leaders employ a variety of themes and narratives to highlight their activities, resulting in four types of images: competence-oriented, benevolence-oriented, party-loyalty-oriented, and versatile. Case studies reveal how the configuration of conditions, such as the official’s age, professional background, political connections with the top leader, and the socioeconomic characteristics of their province, relate to their image-building strategies. The findings, which are supported by methods including topic modeling, machine learning, and fuzzy-set qualitative comparative analysis, contribute to the literature on political propaganda by emphasizing the diversity of public images among senior political elites in non-democratic systems.

Optimizing modeling the multilayer coextrusion flow of non-newtonian fluids through rectangular ducts: appropriate shear rate definition for a local power law formulation
Authors: Naderer Thomas , Hammer Alexander , Roland Wolfgang , Zacher Maximilian , Berger-Weber Gerald
Published: February 2025

The accuracy of viscosity predictions is a crucial aspect of polymer melt flow modeling and essential for the design of coextrusion die systems. In the field of non-Newtonian fluid modeling for coextrusion flows through rectangular ducts, significant progress has been made in understanding multilayer flow dynamics. Our fundamental research, employing numerical techniques such as the shooting method, finite element method, and finite difference method for flow evaluation, has established a critical base for the field. Our current research advances fluid dynamics by refining our existing numerical solver, specifically developed for multilayer coextrusion flows. We aim to enhance the solver’s performance by implementing more sophisticated calculations of shear rates that go beyond the traditional approach. The traditional approach often relies on average flow velocities and channel heights, which can underrepresent the complexity of experimentally studied polymer multilayer flows. Our study systematically compares various definitions for characteristic shear rates to describe the local shear rate dependent viscosity behavior using, for instance, a local power law model. A thorough error analysis quantifies the accuracy of each model and its predictive limitations for industrially relevant material combinations and operating conditions. This includes CFD simulations and experimental data comparisons, employing methods aligned with our fundamental research in this area. Furthermore, our work paves the way for integrating these advanced fluid dynamics models into the evolving field of process digitalization, thereby contributing to the development of more efficient, digitally integrated manufacturing processes.
Formulation of highly electro-conductive thermoplastic composites using PEDOT-based fillers with controlled shape factor
Authors: Karst Adèle , Bouquey Michel , Soulestin Jérémie , Samuel Cédric , Parpaite Thibault
Published: February 2025

The objective of this study is to develop a new conductive thermoplastic material with superior electrical properties. Currently, conductive polymers are typically filled with carbon or metallic particles [1]. However, these filled thermoplastics exhibit drawbacks such as high rigidity, toxicity, and high viscosity [2]. An alternative approach investigated in this work is to substitute these fillers with intrinsically conductive polymers like Poly(3,4-ethylenedioxythiophene) (PEDOT). PEDOT can achieve exceptional electrical conductivities (over 1000 S.cm-1) when combined with polymeric dopants like poly(styrene sulfonate) (PSS) and is frequently used in thin films or gels in medical and energy applications [3]. However, incorporating PEDOT into the conventional hot melt processes of the plastic industry remains challenging [1].
Effect of jatropha curcas oil on the thermorheological properties of asphalt binder modified with recycled HDPE
Authors: Machute Ana , Tamele Jr. Lucas , Manhique Arão , Macheca Afonso , Muiambo Hermínio
Published: February 2025

The application of bio-oils in asphalt and polymer-modified asphalt (PMA), has recently received considerable attention as a pivotal method for enhancing the high-temperature performance of asphalt mixtures while maintaining good binder’s workability. In this study, Jatropha curcas oil (JCO) was selected and evaluated as an PMA modifier. JCO-rHDPE-modified bio-asphalt was prepared with different JCO contents: 1, 3, and 5 wt.%. Physical tests (penetration, softening point, and ductility), rheological tests (dynamic viscosity and rolling thin-film oven test–RTFOT), and thermogravimetric analysis (TGA) were employed to evaluate the effect of JCO on the rheological, aging, and thermal properties of unmodified and HDPE-modified asphalt. The addition of JCO was effective in reducing the age hardening of asphalt binders due to an increase in penetration and ductility and a decrease in the softening point, and penetration index values. Aged asphalt binder with a combination of JCO and rHDPE has improved resistance to thermo-oxidative aging, exhibiting lower oxidation and volatilization after RTFOT. TGA indicated that the addition of JCO and rHDPE increases the thermal stability of modified binders by delaying the initial decomposition temperature of neat asphalt by 10ºC. The incorporation of JCO leads to a decrease in the viscosity of both virgin and rHDPE-modified asphalt. Thus, JCO-rHDPE-modified asphalt has better workability as well as potentially reduced fuel consumption and harmful emissions at pavement service temperatures.

Abstract: Market facilitates the trade of goods and services. Similarly, financial market facilitates the sale and purchase of financial assets/instruments. And the financial market comprises two major markets viz., capital market and money market. Capital market is important for mobilizing funds for capital formation and investments, and forms a very vital link for economic development of any country. It (i.e., capital market) provides ways for issuers to mobilize capital from investor. The primary objective of the study is to assess and analyse the level of awareness among the respondents about capital market operations and different investment avenues. The study is based on the data/material collected from both primary and secondary sources. Random sampling method is used to select the respondents. And the sample size is 100 selected from different categories of investors and investment advisors. The major findings of the study are majority of the respondents prefer life insurance policies and bank deposit schemes for their investment. Real estate, gold, government bond and co-operative societies (shares) are also preferred investment avenues. Majority of the respondents are investing for medium (1 – 3 years) to long term (3 years and more). And the remaining is investing for less-than one-year period. Finally the outcome of the research is concluded as follows The retail investors from Shivamogga city have certain problems as can be seen other parts of the state/country. In spite of these problems, investment in capital market is slowly picking up. While knowledgeable investors have remained in the market for long, others forget it and exit. This situation has to improve.

The levels of Polycyclic Aromatic Hydrocarbons in Produced Water and the receiving Ugborodo River at Escravos, Nigeria were assessed in this study using Gas Chromatography-Mass Spectrometer. The results showed total PAH levels ranged between 0.726 and 1.215 ppm across all sampling stations. The maximum PAH level in fish sample A was 0.00573 ppm and in fish sample S was 0.00042 ppm. The Total Polycyclic Aromatic Hydrocarbon (PAH) levels were above the WHO limit of 0.0002 mg/L. The PAH levels obtained in this study may pose serious environmental and health risks due to bioaccumulation of these PAH compounds. There was significant difference in the levels of PAHs between the stations as well as the fish types. Thus, adequate treatment of the surface water in the study areas is recommended as this could reduce the PAHs levels in aquatic lives.

The article provides a literature review on the anatomy, physiology, diagnosis and treatment of diaphragm eventration in children. There are congenital and acquired variants of pathology. The reason of congenital eventration development is a malformation of its muscle layer. The main reasons of obtained diaphragmatic eventration in children are damage of the phrenic nerve during surgical correction of congenital heart defects (CHD), birth trauma or catheterization of central veins. Injuries of the phrenic nerve, accompanied by diaphragm eventration, are registered after cardiac surgery with a 0.3 % to 12.8 % rate. The frequency of this complication in the Republican Scientific and Practical Center of Pediatric Surgery (Belarus) was 2.54 % in 2021; 2.94 % in 2022; 3.16 % in 2023. The increase in the diaphragm eventration number after cardiac surgery is associated with an increase in the complex surgeries number in the structure of surgical activity, as well as the number of repeated heart operations (resternotomies).

Diffuse polyposis of the colon is a genetically determined disease that affects young people, inherited according to the principle of autosomal dominance with an 80 % degree of penetration of the APC gene and an almost 100 % malignancy index. Total coloproctectomy is the only radical method of treating diffuse colon polyposis, which leads to disability of the patient and is accompanied by impaired sexual and reproductive function. Total colectomy provides better functional results, but the remaining portion of the rectum can become a source of recurrence of polyps and lead to the development of rectal cancer. Laparoscopic coloproctectomy is a modern method of treating diffuse colon polyposis that meets the requirements of early rehabilitation of patients, has optimal functional results while maintaining oncological principles of radicalism by removing malignant tumors. This article reflects our unique experience of performing laparoscopic coloproctectomy with D3 lymphodissection in a patient with multiple primary colorectal cancer in the background of diffuse colon polyposis. The use of laparoscopic techniques provided the opportunity for early rapid rehabilitation (the patient was discharged on the 13th day in satisfactory condition) with subsequent good functional, psycho-emotional and social results when assessing the quality of life using the SF-36 questionnaire. At the same time, all the principles of oncological radicalism are observed, including the non-routine performance of D3 lymphodissection. Based on the results of histological and moleculargenetic studies, a decision was made to carry out chemotherapy in CapeOx regimen. During the control CT study and determination of the level of tumor markers six months after the operation, no evidence of progression was obtained.

PULSE WAVES. ROLE IN THE IMPLEMENTATION AND REGULATION OF HEMODYNAMICS. PART 1. TYPES OF PULSE WAVES, ORIGIN, PROPAGATION, REGISTRATION AND ANALYSIS; RELATIONSHIP OF PARAMETERS WITH HEART FUNCTION AND HEMODYNAMICS
Authors:   Belarusian State Medical University, A. I. Kubarko , I. M. Gurinovich ,   Belarusian State Medical University
Published: February 2025

Pulse waves and the response of arterial vessels to changes in hemodynamics have been studied in 121 subjects, of which 58 women and 59 men were of age 21.5 ± 1.6 years old, and 4 subjects 63–79 years old. Pulse waves were recorded by two methods: using photoelectric and mechanoelectric sensors, synchronously with ECG in 2nd standard lead. The reaction of small arteries and arterioles was recorded by method of microspectrometry. Based on the analysis of the results of this study and literature data, the following conclusions and assumptions can be made: – the use of sensors that respond to mechanical pulsating displacements of the arterial wall caused by changes in blood pressure in the systole and diastole of the heart allows recording pulse pressure waves. The use of sensors sensitive to changes in the volume and velocity of blood flow makes it possible to record pulse flow waves. Synchronous recording of pulse oscillations with these two types of sensors makes it possible to record both types of pulse waves; – pulse pressure waves propagate along the arterial wall at a higher velocity than the velocity of pulse flow wave in blood, and pulse pressure wave is recorded earlier than flow wave; – pulse waves parameters (amplitude, steepness of anacrotis, duration of delay of onset of anacrotis relative to R wave on ECG, delay pulse flow waves relative pulse pressure waves, pulse waves propagation velocity) depend on the rate of myocardium excitation, stroke volume, arterial pressure and volume of blood flowing into arterial vessels. Additional research is required to verify the assumptions made about the role of pulse waves in implementation and regulation of hemodynamics in a healthy body, and the possible significance of its disturbance in the mechanisms of development of cardio vascular and other diseases.

Arterial switch operation was performed in 305 children with TGA at the RSPC “Cardiology” and RSPC of Pediatric Surgery from 2004 to 2024 years. Mean age of the children was 11.2 ± 3.8 days. Simple TGA was in 213 children (69.8 %). GA with ventricular septal defect was in 67 patients (22.0 %). Double outlet right ventricle with TGA (Taussig-Bing anomaly) was in 24 children (7.9 %). Congenitally corrected TGA with ventricular septal defect was in 1 patient (0.3 %). Results. There were 18 deaths (5.9 %) during hospital stage after arterial switch operation, postoperative complications were diagnosed in 13 patients (4.3 %). Long-term period was studied in 253 children (83.0 %) after arterial switch operation. Mean follow-up duration was 8.1 ± 4.7 years. Neo-AV repair was performed in 1 patient (0.4 %), neo-AV replacement with mechanical prostheses was performed in 3 children (1.2 %) in long-term period after arterial switch operation.

According to the World Health Organization in 2019, for a citizen of Belarus, the probability of death (aged 30 to 70 years) from any of the four major non-communicable diseases (NCDs) is 23.8 %. Developing interventions to prevent chronic NCDs requires evidence to characterize the prevalence of behavioral risk factors. The contribution of insufficient daily consumption of vegetables and fruits to premature mortality from chronic NCDs is 12.9 %, and to the loss of healthy years of life – 6.9 %. It is of scientific interest to study the characteristics of the consumption of vegetables and fruits as alimentary risk factors in an urbanized environment. In the Republic of Belarus, the state preventive project “Healthy cities and towns” has been implemented in 2012 and in 2024 the project unites 379 settlements. Aim. to assess the prevalence of consumption of vegetables and fruits as risk factors for the development of chronic NCDs in residents of settlements participating in the implementation of the state preventive project “Healthy cities and towns”. Material and methods. The work was carried out within the framework of the initiative research “To develop an algorithm for assessing the effectiveness of the state preventive project” Healthy cities and towns. “ The material for the study was the data of a sociological study on the prevalence of behavioral risk factors for the development of NCDs in the population aged 18–69 years, conducted in 6 regional centers from 6 regions of the Republic of Belarus, implementing the state preventive project “Healthy cities and towns” for at least 4 years (n = 1608). Results. A sufficient level of daily consumption of vegetables and fruits is noted in 30.35 %. Daily in the diet there are vegetables in 43.12 %, fruits - in 35.95 % of the population. Every seventh adult practically does not eat vegetables (14.37 %) or consumes them 1–2 times a week, and every sixth (15.86 %) - fruits. The frequency of daily consumption of vegetables and fruits is higher among women. With age, there is an increase in the frequency of daily consumption of vegetables and fruits from 28.69 % and 19.92 % among people 18–30 years old to 47.24 % and 40.71 % at 51–69 years old. Statistically significant differences in the consumption of fruits and vegetables were established depending on the duration of the implementation of the state preventive project “Healthy cities and towns.” Conclusion. The results of the study indicate that higher population activity in the consumption of vegetables and fruits is associated with female gender and older age and significantly differs depending on the region.

It is relevant to determine the characteristic parameters of physiological anemia in young children, which does not require correction. Differential diagnosis based on these parameters will identify pathological cases of anemia that require adequate correction. Pathological variants of anemia during this period are associated both with the pathology of pregnancy and childbirth, and with diseases in the postpartum period. Then the iron deficiency state is revealed, as well as the effect on erythropoiesis of various diseases – anemia of chronic diseases – ACD, etc., requiring multidirectional correction. Purpose of the study: to establish the features (patterns) of physiological anemia in young children in order to identify cases of pathology that “fall out” from this group. The results of a survey of 526 patients, aged from 4 days to 8 months, who were treated and examined in departments of various profiles of the 3rd State Children’s Clinical Hospital in Minsk in 2021–2023 (in the early childhood departments and the rehabilitation department) were analyzed. The following indicators were studied: erythrocyte content, hemoglobin, color index, MCV, MCH, reticulocytes, reticulocyte hemoglobin, serum iron, serum ferritin. C-reactive protein.

Abstract. This study assessed the metabolic, reproductive, and udder health profiles of pure Holstein-Friesian (HF) cows and their Sahiwal crossbreeds (F1, F2, F3) under sub-tropical conditions. A total of 180 dairy cows were evaluated over 8 weeks postpartum, focusing on milk yield, serum metabolites (glucose, cholesterol, triglycerides, calcium, cortisol, and progesterone), somatic cell count (SCC), and reproductive performance. F2 cows exhibited the highest milk yield, particularly by week 6, with an overall weekly yield of 183.9 L, while HF cows had the lowest yield at 140.3 L. Serum glucose levels were highest in F2 cows during week 5, and cortisol was significantly higher in F2 cows than in other breeds. However, no significant differences were observed in cholesterol or triglyceride levels across the breeds, suggesting consistent metabolic management. The SCC was significantly higher in pure HF cows, indicating a greater susceptibility to sub-clinical mastitis. Reproductive performance, measured by the postpartum estrus interval (PEI) and the interestrus interval (IEI), declined with increasing HF genetics, with F1 cows showing the best adaptation to local conditions. Progesterone levels were higher in F1 cows, supporting better luteal activity and ovarian resumption. The study concludes that crossbreeding HF with Sahiwal improves milk production and reproductive health while reducing the risk of mastitis, with F1 and F2 cows showing the most favorable outcomes.
Building multi-satellite DEM time series for insight into mélange inside large rifts in Antarctica

Abstract. Front calving is a primary mechanism through which Antarctic ice shelves discharge ice mass into the Southern Ocean. It is an important process that influences ice shelf stability and thus, impacts the Antarctic Ice sheet’s contribution to global sea level rise. However, there has been a significant gap in large-scale, high-resolution observations of three-dimensional (3D) rift structural changes and mélange dynamics, which hinders our understanding of the role of mélange in ice shelf retreat and mechanisms underlying the weakening of ice shelf stability. We propose an innovative multi-temporal DEM adjustment model (MDAM) that builds a multi-satellite DEM time series from meter-level resolution small DEMs across large Antarctic ice shelves by removing biases, as large as ~6 m in elevation, caused by tides, ice flow dynamics, and observation errors. Using 30 REMA and ZY-3 sub-DEMs, we establish a cross-shelf DEM time series from 2014 to 2021 for the Filchner-Ronne Ice Shelf, the second largest in Antarctica. This unified and integrated DEM series, with an unprecedented submeter elevation accuracy, reveals quantitative 3D structural and mélange features of a ~50 km long rift, including rift lips, flank surface, pre-mélange cavities, and mélange elevations. For the first time, we have observed that while the mélange elevation decreased by 2.1 m from 2014 to 2021, the mélange within the rift experienced a rapid expansion of (7.93±0.03) × 109 km3, or 130 %. This expansion is attributed to newly calved shelf ice from rift walls, associated rift widening, and other factors related to rift-mélange interactions. The developed MDAM system and the 3D mélange dynamics analysis methods can be applied for research on ice shelf instability and the future contribution of the Antarctic Ice Sheet to global sea level rise.

Abstract. Warm-water coral reefs are facing unprecedented human-driven threats to their continued existence as biodiverse functional ecosystems upon which hundreds of millions of people rely. These impacts may drive coral ecosystems past critical thresholds, beyond which the system reorganises, often abruptly and potentially irreversibly; this is what the Intergovernmental Panel on Climate Change (IPCC, 2022) define as a tipping point. Determining tipping point thresholds for coral reef ecosystems requires a robust assessment of multiple stressors and their interactive effects. In this perspective piece, we draw upon the recent global tipping point revision initiative (Lenton et al., 2023a) and a literature search to identify and summarise the diverse range of interacting stressors that need to be considered for determining tipping point thresholds for warm-water coral reef ecosystems. Considering observed and projected stressor impacts, we endorse the global tipping point revision's conclusion of a global mean surface temperature (relative to pre-industrial) tipping point threshold of 1.2 °C (range 1–1.5 °C) and the long-term impacts of atmospheric CO2 concentrations above 350 ppm, while acknowledging that comprehensive assessment of stressors, including ocean warming response dynamics, overshoot, and cascading impacts, have yet to be sufficiently realised. These tipping point thresholds have already been exceeded, and therefore these systems are in an overshoot state and are reliant on policy actions to bring stressor levels back within tipping point limits. A fuller assessment of interacting stressors is likely to further lower the tipping point thresholds in most cases. Uncertainties around tipping points for such crucially important ecosystems underline the imperative of robust assessment and, in the case of knowledge gaps, employing a precautionary principle favouring lower-range tipping point values.
