The DRC’s production is not enough to cover the country's needs and it has to import large quantities. Abnormal situation when it is known that the DRC, taking into account its resources in irrigation water and arable land, should be the granaries of cereal production for Africa. The problem lies, among other things, in the lack of infrastructure, agricultural inputs, and in particular high-yielding seeds.
This work had the objective of evaluating three new wheat varieties in order to study their agronomic performance under the edapho-climatic conditions of Lwiro. To achieve this, a test was installed at the Center for Research in Natural Sciences, in the experimental field of the Agricultural Entomology Laboratory. It was carried out in the period from March to July of the year 2022. The sketch is a completely randomized design with three repetitions having a total of 12 treatments.
The recovery rate is considered favorable because it exceeds 90%; all the varieties have a medium cycle since it oscillates around 120 to 150 days. About the growth and yield parameters, the results revealed differences between varieties under study.  Except for the number of tillers for which the analysis of variance did not show any significant differences, for the height of the plants (the averages of which vary between 53-77 cm) and the number of leaves per plant (the averages vary between 12 and 25); the KIMA variety was better compared to MBALALIZI and LUBERO. For the number of grains per ear, the weight of 1,000 grains as well as the yield, the KIMA variety still proved to be the most adapted to the environment with productions of more than 3 T/ha (3.22 T/ha) of the homogeneous group A, followed by MBALALIZI (2.51 T/ha) and finally by LUBERO (2.30 T/ha) constituting the homogeneous group B. Thus, the KIMA variety would seem to be indicated for the promotion of wheat in the region.

Published: July 2024

Introduction: Nursing is an important profession in the Kingdom of Saudi Arabia, with nurses comprising more than 80% of the individuals providing health care services, which will increase by 2030. Therefore, developing and maintaining effective nursing leadership is critical to achieving organizational goals and maintaining quality of care despite the challenging healthcare environment. Methods: The data were collected through the distribution of two tools, the Hospital Anxiety and Depression Scale, as a tool to evaluate stress, and the Leadership Style Questionnaire, among 204 nurse workforce members and 57 middle-level nurse managers who belong to Prince Sultan Military Medical City, Riyadh City, Kingdom of Saudi Arabia. The study used a cross-sectional survey design and descriptive correlation analysis. Results: The study indicated associations of age, nationality, and years of working experience as demographic characteristics with the level of stress experienced by the participants. No association was found between demographic characteristics and depression. Moreover, the study illustrated that middle-level leaders show different leadership styles. The findings also indicated an association between years of working experience and a democratic leadership style. In conclusion, no single leadership style is appropriate for every leader in every situation. Demographic characteristics such as age, nationality, and years of working experience showed associations with the level of stress experienced by the nurse workforce. However, they had no association with depression. Conclusion and Recommendation: Investigating the key reasons for the development of stress and depression in nursing staff is crucial. Accordingly, nurses must have opportunities to voice their complaints and ideas about improving the work environment. Educating nurse managers and head nurses about the different styles of leadership; and, how they should select suitable managerial aspects to fit the situation is also important. Further investigations are indicated to explore what triggers stress and depression among the nursing workforce.

Navigating the Path to Efficient and Just Transition to Carbon Neutrality: A Case Study of Agricultural Practices in Foya District, Liberia
Authors: Eddie Kanneh
Published: July 2024

The importance of shifting towards carbon-neutral agriculture is increasingly recognized globally, particularly in developing countries. This study focuses on Foya District in Liberia, examining the relationship between traditional farming methods and emerging sustainable practices, and evaluating the carbon footprint of local agricultural activities. To address this, a novel framework called the Adaptation Strategies Index and Problem Confrontation Index (ASI-PCI) has been proposed to evaluate the hurdles local farmers face in adapting to climate change, along with their adaptive behaviors and strategies. The ASI of 564 highlights the use of drought-resistant crops, while the PCI of 566 indicates significant challenges due to extreme climate events. Key sources of greenhouse gas emissions identified include deforestation, land use changes, and rice cultivation. Quantitative data reveals that 63% of farmers engage in rice cultivation, 39.3% in deforestation, and 27.7% in land use changes, contributing to carbon emissions. The Multiple Linear Regression (MLR) analysis showed that education level positively influences farmers' strategies for carbon-neutral agriculture (P <.001), validating the initial hypothesis. The study explores strategies to reduce emissions, such as introducing drought-resistant crops, implementing irrigation systems, adopting mixed cropping practices, and promoting agroforestry. The study emphasized the pivotal role of women in participating in local farming initiatives, highlighting the group's potential for better carbon-neutral agriculture practices. It underscores community engagement's importance in identifying barriers to adopting carbon-neutral practices. The insights gained aim to guide rural communities in the region and beyond, providing a framework for policymakers, stakeholders, and practitioners to develop pathways toward carbon neutrality that support local economic stability and development.

Authors: Touray Neneh , Zhou Xuefei
Published: July 2024

Floods rank as one of the most common natural calamities, impacting the lives of millions across the globe. With ongoing population growth and expanding water and land usage, the potential for contamination and human disturbances to negatively impact water bodies continues to rise globally. This paper aims to comprehensively analyze the repercussions of floods on the groundwater quality of a region called CRR in the Gambia, during the July 2022 flood event. The focus lies on exploring the change in water quality parameters of twelve water samples from wells and boreholes through laboratory analysis of eight parameters such as pH, turbidity, temperature, electrical conductivity, total dissolved solids, nitrate, iron, sulfate, and microbial proliferation. The laboratory analysis results of the physiochemical parameters such as turbidity, and iron exceeded the safe drinking water standards set by the World Health Organization (WHO) in about 60% of the sites and fecal coliform presence in 75 % of the samples. The other parameters varied differently across all sites. However, most of the values are observed to be more prominent at the open well than borehole. The Water Quality Index (WAWQI) score also shows that 1 site has excellent water quality, 25%, has good quality and 25% has fair quality. The rest of the sites which make up 42% of the samples, are all of poor quality and unsuitable for drinking purposes. The results provide a crucial groundwork for subsequent studies targeting the water quality in this area.

The structure from which this study was carried out is a food processing company specializing in the transformation of crude palm oil into table oil. In order to comply with environmental standards when discharging the refinery's wastewater, it has its own wastewater treatment unit. The aim of this study is to contribute to environmental protection by recovering grease and bleaching earth through biogas production by anaerobic digestion. The characterization provided us with moisture, dry matter and volatile solids contents the values obtained are 32.31%, 67.69% and 97.57% respectively. In the same order, those for bleaching earth are 1.80%, 98.20% and 59.97%. The values obtained during the characterization of the bleaching earth are not conducive to good anaerobic digestion. To optimise biogas production from fat, we used inoculums such as cattle dung and broiler droppings. Biodegradability tests carried out with different proportions of substrates and inoculums led to the conclusion that the presence of a large quantity of microorganisms is necessary for optimum biogas production. In addition, the grease produced a good quantity of biogas when co-digested with the inoculums. The cumulative volume of biogas obtained over 30 days with the grease was 445 ml. The highest quantity of biogas obtained by optimising gas production is 780 ml.

This study investigates poverty dynamics in Uganda, employing an extensive stability analysis of different socioeconomic indicators to understand long-term trends and likely drivers of poverty. An eighteen years yearly secondary data from 1992 to 2020 on poverty rates for the selected indicators under review sourced from World Bank site was utilized for all the data analysis. Outcomes from extensive data analysis shows considerable reductions in poverty rates over time, especially in outlying areas of eastern and northern Uganda despite increasing income inequality as suggested by the increasing Gini coefficient. All the metrics have a significant impact on Uganda's poverty rates, with the exception of the poverty headcount ratio, which stands at USD 6.85 per day (2017 PPP) as a percentage of the population. Particularly, the forecasted values also show a fluctuating trend movement, both downward and upward, suggesting possible variability in future poverty rates in Uganda. The necessity to carefully evaluate as well as monitor poverty dynamics to guide policy interventions aimed at reducing poverty is underlined by this information. Additionally, the stability analysis framework suggested in this research provides insights into the viability as well as resilience of Uganda's socioeconomic system in tackling poverty, enabling evidence based policies and interventions in poverty reduction. The study suggests more examination of various other dimensions of poverty and non-monetary indicators of well-being to better our understanding and support better poverty alleviation methods in Uganda along with other similar settings.

Breast cancer diagnosis is a critical area in medical research, where the challenge lies not only in accurate identification but also in managing the inherent complexity of high-dimensional datasets. This paper navigates this challenge by exploring dimensionality reduction techniques to enhance diagnostic accuracy. The primary objective of this research was to employ dimensionality reduction methods to refine breast cancer diagnosis, with a focus on improving accuracy and interpretability. The study investigates the impact of preprocessing techniques on a high-dimensional dataset, aiming to uncover meaningful patterns for effective diagnostic models. Starting with a dataset including 569 observations and 30 attributes, careful examination reveals imbalances in the dataset (63% benign, 37% malignant). To deal with multicollinearity, we use the coefficients of Pearson correlation to find and eliminate highly correlated features. Subsequent data transformation, utilizing min-max normalization, ensures uniform weighting. Principal Component Analysis (PCA) is then leveraged for comprehensive dimensionality reduction. Visualizations through scree plots and bi-plots underscore the efficacy of early principal components in distinguishing benign from malignant cases. Our results demonstrate a notable 24% reduction in data dimensionality, affirming the process's efficiency. This abstract beckon the exploration of detailed findings, emphasizing dimensionality reduction's pivotal role in refining breast cancer diagnosis for more accurate, efficient, and interpretable models.

The main purpose of this paper is to explore the conceptual structure of strategic management accounting (SMA) research over the past 40 years to reveal and synthesize research trends in the field. To achieve this goal, we applied a bibliometric approach to analyze 326 peer-reviewed articles retrieved from Scopus and Web of Science databases. We conducted a co-word analysis using the VOSviewer software. The bibliometric analysis reveals the main outlets that published articles on SMA, and the most prolific authors and cited articles. Our findings reveal four main research streams in this field as follows: (i) SMA as a source of competitive advantage, (ii) strategic performance measurement systems, (iii) the SMA adoption and context of use, and (iv) the role of SMA in the strategic management process. For each research stream, we systematize some research themes. Additionally, our findings highlight potential emerging topics, such as the role of SMA in the integration of sustainability within companies’ strategy; and new settings of study, which represent opportunities for further research. Thus, this paper intends to support researchers in positioning their future research efforts.

Authors: Yang Liu , Yang Pujian
Published: July 2024

Using the transaction data of the stock market and financial data of listed companies from 2003 to 2021 in China, we explore the existence form of the disposition effect. Then, we combine the Bayesian learning process with the DSSW model to investigate the disposition effect's size and performance when market conditions differ from investors' irrational beliefs. We find the disposition effect in China is asymmetric V-shaped and negatively correlates with investor sentiment significantly. In addition, affected by sentiment, its performance is opposite in the bull market and bear market. The above research and conclusions have theoretical and practical significance for understanding the disposition effect, optimizing investors' decision-making, and strengthening the capital market infrastructure.

Utilizando los datos de transacciones del mercado de valores y los datos financieros de las empresas cotizadas de 2003 a 2021 en China, exploramos la forma de existencia del efecto de disposición. A continuación, combinamos el proceso de aprendizaje bayesiano con el modelo DSSW para investigar el tamaño y el rendimiento del efecto de disposición cuando las condiciones del mercado difieren de las creencias irracionales de los inversores. En China, el efecto de disposición tiene forma de V asimétrica y una correlación negativa significativa con el sentimiento de los inversores. Además, afectado por el sentimiento, su rendimiento es opuesto en el mercado alcista y en el mercado bajista. La investigación y las conclusiones anteriores tienen importancia teórica y práctica para comprender el efecto de disposición, optimizar la toma de decisiones de los inversores y reforzar la infraestructura del mercado de capitales.

In modern implantology composites based on various inorganic and polymeric materials are promising, which are able to provide strong adhesion with tissues in contact with the implanted material and stimulate the growth of new tissue on the implant surface. In the work macroporous cationite Tokem-250 with high selectivity to Zn2+ ions was used as a matrix, which makes it possible to use it in the development of biomaterials. Zinc has a direct stimulating effect on bone tissue formation and has antibacterial properties. For the cationite Tokem-250 based on acryl-divinylbenzene matrix the values of total exchange capacity and sorption capacity in relation to Zn2+ ion were determined. Total exchange capacity of cationite Tokem-250 is 10.35 mmol∙ekv/g, sorption capacity is 73% of the total exchange capacity and is equal to 7.58 mmol∙ekv/g. Spherical composites TiO2-SiO2-P2O5/ZnO on the basis of cationite Tokem-250 were synthesized from alcohol solutions by sol-gel method. For obtaining spherical composite the conditions of heat treatment of samples are established: drying at 60 ºC and step annealing at 150, 250, 350 ºC for 30 min at each temperature step, at 600 ºC - 6 h, at 800 ºC - 1 h. The obtained composites have the ability to precipitate and mineralize calcium-phosphates on their surface in biological media, because they have homogeneous structure with uniform distribution of elements on the surface, mesoporous structure with pore size from 5 to 12 nm and the presence of active centers (Si4+, Ti4+) on the surface of composites. The use of polyvinyl alcohol as a binder does not prevent the formation of an apatite-like layer.

Published: July 2024

A systematic study of proton NMR spectra of pyrido[1,2-a]benzimidazole and 65 of its mono-, di- and poly-substituted derivatives with substituents in the pyridine and/or benzene fragment was carried out. The choice of certain structures is related to the great practical significance, as well as the complexity of interpreting their 1H NMR spectra. As a result of the research, a number of general patterns of arrangement (characteristic ranges) on the scale of chemical shifts of signals of hydrogen atoms associated with the nucleus of the studied heterocycles have been established. In the 1H NMR spectrum of pyrido[1,2-a]benzimidazole and most of its derivatives, the H1 signal of the pyridine cycle associated with a carbon atom was released in the weakest field, which experienced a strong electron acceptor effect of the nodal endocyclic nitrogen atom. The signal of another heteroaromatic proton H2 was usually detected in the strongest field region of the spectrum. The H8 signal had the smallest chemical shift among the aromatic protons. As the analysis of 1D 1H NOE spectra of a series of pyrido[1,2-a]benzimidazoles showed, this position of the heterocycle was the reaction center for the introduction of an electrophilic particle under SEAr reaction conditions. The H9 signal was detected in a weaker field relative to other aromatic protons. The influence of the electronic nature of the substituent and its position in the condensed heterocycle on the distribution of the electron density in the molecule has been established. It is concluded that the transmission of electronic effects of substituents in pyrido[1,2-a]benzimidazoles differs from benzoid systems. A number of controversial proton signals were attributed by means of 1H-1H NOESY and 1H-15N HMBC spectroscopy. The conducted studies will allow to use the data of 1H NMR spectroscopy to determine potential reaction centers in pyrido[1,2-a]benzimidazoles and other similar condensed pyridine derivatives with a nodal nitrogen atom.

VALORIZATION OF WASTE FRUIT PEELS: A COMPUTATIONAL STUDY ON PREDICTION OF GASIFICATION PRODUCT COMPOSITION
Authors: Khedkar Rohit S. , Khonde Ruta D. , Meshram Pawan
Published: July 2024

In this work, a variety of discarded fruit peels are investigated using a computational technique in order to anticipate the products of their gasification when subjected to higher temperatures, namely 800°C and 900 °C. The proximate and ultimate analyses of eight different fruit peels were collected from a variety of published sources, and the composition of gasification was predicted by applying the Gibbs free energy minimization method to each fruit peel individually and to both temperatures using the Solver Tool feature of the Microsoft Excel Spreadsheet. As input for the simulation, the thermodynamic constants for each gaseous component and the elemental analysis of each fruit peel were needed. The predicted gaseous composition was compared with some of the data obtained in the literature, and it was determined to be in a close match based on the root mean square error for each number. This was done while taking into account the fact that the carbon conversion process during gasification was only partially successful.

The development of new functional materials based on modified styrene-butadiene block copolymers will enable the creation of materials with improved resistance to gasoline, heat, light, ozone, and enhanced adhesive properties. This study investigates the influence of chlorinated paraffin on the properties of the styrene-butadiene-styrene triblock copolymer. Chlorinated paraffins (CP), complex mixtures of polychlorinated n-alkanes, were used as halogen-containing modifiers for the thermoplastic elastomer to enhance its tensile and adhesive strength and thermal properties. Composite materials based on styrene-butadiene-styrene copolymer (SBS) with various amounts of chlorinated paraffin were prepared using a solution mixing method. The analysis of the ATR/FT-IR spectra of neat SBS and SBS/CP revealed the appearance of new characteristic absorption bands at 1260, 1090, 1020, and 800 cm-1. The study determined that the amount of chlorinated paraffin strongly influenced specific properties of the examined TPE. It was observed that chlorinated paraffin improved the thermal stability of the composites. The onset temperature of degradation increased to 262 °C (a rise of 57 °C), while the maximum degradation temperature slightly increased from 463 to 467 °C. The impact of the concentration of chlorinated paraffin on the chemical structure and tensile properties was evaluated and compared to those of neat styrene-butadiene-styrene. It was estimated that SBS composites with 5 ppm. CPs are characterized by improved strength properties in comparison with the original SBS sample.
