Analysis of Near Infrared-Emitting Bimolecular Excited States in Platinum(II) Complexes with Simple Computational Tools
Authors: Pander Piotr
Published: August 2022

This work presents a simple computational methodology for analysing and predicting luminescence originating from bimolecular excited states, dimers and excimers, of platinum(II) complexes. Photoluminescence spectrum of said species resembles Gaussian distribution. Gaussian perfectly fits PL spectra in the region of interest from the onset to peak and given its simplicity serves as a perfect model for experimental data. Time-dependent density functional theory (TDDFT) methods provide computational data which are then correlated with the features of the experimental PL spectrum: peak and onset energy. Good linear correlation (r2 = 0.94) between experimental and computational data yields high precision predictions of PL spectra based on the simple computational model. A diverse selection of platinum(II) complexes used for calibration of the model guarantees generality. The study provides an insight into the structure of dimers/excimers of platinum complexes, suggesting that anti or head-to-tail configuration is preferred.

We review the current status of the development of sources of epithermal neutrons sources based on reactors and accelerators for boron neutron capture therapy (BNCT), a promising method of malignant tumor treatment. The scheme is proposed of the source prototype for the production of thermal and epithermal neutrons using the delayed neutrons generated with help of linear electron accelerator at the target containing the fissile material. The results of an experiment are presented in which the half-life curves of radioactive nuclei formed during fission and emitting delayed neutrons are measured. It is shown that an activated target containing fissile material is a compact small-sized source of delayed neutrons. It can be delivered to the shaper, where, using a moderator, an absorber, and a collimator, neutrons of thermal or epithermal energies are formed over a certain period of time, after which this target is sent to the activator, and another target comes in its place. Thus, a pulsed neutron flux is formed. Such a neutron beam can be used in nuclear medicine, in particular, in neutron capture therapy in the treatment of cancer. An important task in the implementation of neutron capture therapy, when irradiating patients, is to control both the intensity and the energy spectrum of the neutron flux. To solve this problem, an earlier developed activation-type neutron ball spectrometer can be used, which will allow optimization of various parameters of the shaper, collimator and filters in order to obtain the most powerful neutron fluxes.
Enhancing Si Solar Cells Efficiency by Adding SiO2 / TiO2 Thin Films Using Transfer Matrix Method
Authors: Garhoom Wedad Ahmed Abdullah , Shadidi Zina Al
Published: August 2022

Thin film silicon solar cells are nowadays the best choice to get electricity due to their low cost compared to the crystalline solar cells. However, thin film silicon solar cells have weak absorption of incident light. To deal with such a weakness and get better efficiency of these cells, an efficient back reflector composed of multilayer thin films (Silver, Silicon dioxide (SiO2) and Titanium dioxide (TiO2)) will be used. The transmitted light from the first silicon layer will be reflected by the next layer, and the reflected light will go back to the first silicon layer. By this way, the absorbance of the silicon solar cell can be increased by an increase in the probability of the light reflection from the SiO2, TiO2 and Ag. The transfer matrix method (TMM) by Matlab program will be used to analyze the results of the reflectance, transmittance and absorbance of the thin film layer and these results can prove the efficiency of the cells by using MATLAB codes.
TAX CULTURE AND TAX MORALE: IMPACT ON TAX COMPLIANCE IN UKRAINE
Authors: Stetsenko Tetiana , Nishcheretov Orest
Published: August 2022

The purpose of writing this article is to assess the impact of tax culture and tax morale on the tax compliance in Ukraine and to develop recommendations for further transformation of the national tax culture. We established that among the reasons for maintaining the size of the shadow sector of the economy in Ukraine is the focus on reforming the tax system, tax administration without taking into account the tax culture that has developed historically. Components of tax culture have different levels of formation. Procedural and technological culture is currently being actively developed. Digitalization and electronic services, involvement in the international fight against tax evasion facilitated this process. The culture of behavior, primarily of taxpayers, was formed spontaneously, without the direction of the process by the authorities. Given the confirmed correlation between tax compliance and tax morale, widespread taxpayer deviant behavior in Ukraine is largely due to low tax morale. The level of tax morale in Ukraine tends to decrease and tends to minimum rather than average values in the sample of World Values Survey`s countries. We determined that the low level of tax morale in Ukraine is caused mainly by the action of institutional factors: distrust of the government, government instability, anti-democratic phenomena and corruption. In Ukraine, for further development of tax culture it is necessary to follow next recommendations: to conduct a large-scale sociological survey to identify all socio-economic and institutional factors influencing the tax morale of domestic taxpayers, as well as to identify the current level of tax literacy; actively introduce tax education at all levels of education. Further research will be related to assessing the level of tax literacy in Ukraine.
POLYVARIANCE OF SCIENTIFIC APPROACHES TO UNDERSTANDING THE ESSENCE OF THE CONCEPT «INVESTMENT SERVICES»
Authors: Yatsenko Ivan
Published: August 2022

The article reflects the results of scientific research of alternative approaches to the interpretation of the definition of investment services. The advantages and disadvantages of the target, production, product, process, instrumental, infrastructural, resource and opportunistic approaches to understanding the essence of the concept of “investment service” are identified and systematized. An improved definition of the concept of an investment service is the result of the choice of an investment idea, analysis of investment information and the use of investment technologies by investment firms in order to realize the financial interests of clients - individual and institutional investors, taking into account their investment profile (expected investment return, maximum losses, risk tolerance and the duration of the investment horizon). The proposed author's approach to the interpretation of the concept of an investment service takes into account the totality of such attributive features as complementarity, substitutionality, analyticity, manufacturability, personification, riskiness and timing. It was found that the providers of investment financial services are investment firms - legal and non-legal entities that on an ongoing basis provide at least one type of investment services to third parties and / or carry out at least one type of investment activity. The recipients of investment services are clients of investment companies - individual and institutional investors. The circle of financial interests of investors was determined, including: increase and mobilization of additional financial resources; accumulation of savings; formation of an optimal investment portfolio in terms of profitability, risk, liquidity, etc .; reducing the negative impact of information asymmetry on investment choice; reduction of transaction costs of investment operations; expanding the list of investment alternatives and deepening the diversification of investment assets; redistribution of risks associated with the provision of investment services. It is established that the definition of an investment service is derived from the generic concept of a financial service. However, if the concept of a financial service is always associated with cash flow, then in the case of the provision of investment services, cash flow is conditioned by the formation and use of investment capital.

Published: August 2022

El cultivo del ñame es de alta importancia para la seguridad alimentaria de las familias rurales en la región Caribe de Colombia. Uno de los principales problemas tecnológicos que enfrentan los pequeños productores es la baja calidad y disponibilidad de la semilla para las siembras. El presente trabajo se realizó con el objeto de evaluar la tecnología de producción de minitubérculos en plántulas de ñame generadas a partir de esquejes, mediante inducción con rizobacterias. Para ello, inicialmente se evaluó in vitro la capacidad de producción de f itohormonas de tres rizobacterias, identif icadas con los códigos DCR11 (Azotobacter vinelandii), DSC21 (Brevibacillus laterosporus) y DSC1 (Bacillus licheniformis), y una vez comprobada su capacidad, se estableció un experimento bajo condiciones de casa de malla para inducir, con las rizobacterias, la producción de minitubérculos en las plántulas de ñame, bajo tres niveles de sombreamiento. Se utilizó un diseño experimental completamente al azar con arreglo en parcelas subdivididas y tres repeticiones, en donde la parcela principal correspondió a los niveles de sobreamiento (0, 65 y 80%), las subparcelas a las tres rizobacterias (DCR11 A. vinelandii, DSC1 B. licheniformis, DSC21 B. laterosporus) y las sub-subparcelas a las dosis del inóculo (0, 2, 4 y 6 mL pl-1). Los resultados in vitro demostraron el potencial de las rizobacterias para producir citoquinas y auxinas. En casa de malla se logró evidenciar la capacidad de producción de minitubérculos por parte de las plántulas de ñame, en donde las rizobacterias DSC1 B. licheniformis y DSC21 B. laterosporus mostraron mayor capacidad de inducción. A partir de los resultados se demostró la viabilidad de producción de minitubérculos en plántulas de ñame bajo condiciones de casa de malla mediante inducción con rizobacterias, por lo que se recomendó su validación a nivel semicomercial como estrategia para la producción masiva de minitubérculos de ñame, como alternativa para la siembra de cultivos comerciales.

El análisis envolvente de datos es una técnica que permite analizar la productividad en términos de ef iciencia, ef icacia, calidad y economía relativas a f in de resolver la productividad de los sistemas de producción. El objetivo de la investigación fue analizar la ef iciencia económica y técnica de 13 unidades representativas de producción (URP) vaca-becerro en México a través del análisis envolvente de datos (DEA por sus siglas en inglés) para probar la hipótesis si las URP con mayor escala de producción son más ef icientes que las de menor escala de producción y la cuantía de la inef iciencia. Las escalas de producción de las URP fueron de 35 a 500 vacas en producción ubicadas en las cinco principales entidades productoras del sistema vaca-becerro. Las URP con mayor ef iciencia económica fueron TM70, TM100 y VE 150; con mayor ef iciencia técnica JA35 y mayor ef iciencia total JA35, CH40, TM70, TM100 y VE150. La ef iciencia económica promedio fue de 73.7±18.2%, la técnica 44.6±27.4% y total 87.1±16.6%; lo que signif ica que las URP pueden aumentar su ef iciencia económica 18.2%, ef iciencia técnica 55.4% y ef iciencia total 16.6% a f in de tener la productividad de la URP de mayor ef iciencia. Además, utilizar cualquiera de los dos insumos proporcionó los mismos parámetros de ef iciencia total. Por lo que, los productores del sistema vaca-becerro en México tienen su mayor oportunidad de crecimiento y desarrollo al mejorar los parámetros técnicos; aunque también pueden hacerlo, pero en menor proporción, con los parámetros económicos.

Published: August 2022

En México no existe un modelo de extensionismo rural diseñado acorde a las condiciones y aspectos propios del país; únicamente han surgido adaptaciones de sistemas de extensionismo basadas en modelos de países desarrollados como Estados Unidos (EE. UU.), las cuales no han permitido obtener los resultados esperados; por tal motivo, el objetivo del presente trabajo es identif icar y analizar los puntos críticos de la operación del programa “Nuevo Extensionismo Rural” implementado en el estado de Michoacán. Se analizó el proceso de extensionismo del ejercicio 2018-2019, la información se obtuvo mediante la observación participante, visitas de campo, talleres participativos; y, análisis, discusión y revisión documental de la operación del componente del estado objeto de estudio. Al realizar el análisis, se identif icaron los tres principales puntos críticos del actual modelo de extensionismo que afectaron el funcionamiento del programa en el estado, los cuales fueron: inexistencia de una evaluación adecuada del impacto del “Nuevo extensionismo Rural” en la producción agropecuaria, desarticulación de las universidades e institutos de investigación, lo cual genera ausencia de un soporte metodológico y, ausencia de una evaluación adecuada del desempeño del extensionista. A pesar de apoyarse en conceptos holísticos, los esfuerzos están dispersos y desarticulados dado que los propósitos se han focalizado en el número de productores atendidos como meta y en el productor como factor adoptante de la tecnología bajo una intervención con enfoque lineal.
PERFORMANCE EVALUATION OF BLACK SOAP (TOILET SOAP) BLENDED WITH DE-OILED JATROPHA CAKE ADDITIVE AS SOLID LUBRICANT IN DIRECT COLD EXTRUSION OF ALUMINIUM ALLOYS
Authors: Yisa Tufion Albert Waindim , David T. Gundu , A. Ashwe , Kuhe Aondoyila
Published: August 2022

The use of petro-lubricants in metal forming leads to lamination of oxide on the extrudates due to temperature increase and reaction of the base metal with some elements in the lubricant, hence resulting poor surface quality of the end product. The non-biodegradability of these lubricants also leads to environmental pollution. Although De-oiled Jatropha Caked has been volarised for so many applications, with some oil left in the cake it can still be employed for use in other applications. In this paper a bio-solid lubricant is formulated from Black soap (Toilet soap-vegetable oil-based) as base and De-oiled Jatropha cake as additive. Jatropha seeds were processed to ≤ 0.5 um particles size powder and de-oiled using Soxhlet apparatus. Black soap and de-oiled Jatropha cake was then mixed in ratios: 90:10, 80:20, 70:30, 60:40 and 50:50. Each of these was further mixed with de-ionized lukewarm water in ratio 50:50 by weight to produce solid lubricant blends B1, B2, B3, B4 and B5, respectively. Each of the Black soap-enriched solid lubricant blends were then used to test for coefficient of friction on mirrored surface prepared aluminum specimens using Ball-on-disc Tribometer. The solid lubricant blends were again used to conduct Extrusion tests on Ø25.4 mm by 25.4mm aluminum alloy billets in direct cold extrusion process on a 2000 KN capacity UT CO821 machine. The results showed blend B3 (70:30) recording the minimum coefficient of friction and extrusion force values μ=0.732 and 170.53KN, respectively. These results reveal that enriched solid lubricant B3 (70:30) is most suitable for aluminum alloys extrusion.

Published: August 2022

Within the last decade, the popularity of entrepreneurship rose exponentially all over the world; however, research in this field within the context of developing countries is still lacking. Generally speaking, accessibility and availability of financial support is one of the most significant factors affecting an entrepreneur’s venture when it is in its initial stages. This is especially true in the case of developing countries such as Pakistan. For this reason, this study explored the drivers and challenges faced by Pakistani entrepreneurs regarding the access to and availability of financial support. Data was collected through 65 semi-structured interviews of budding Pakistani entrepreneurs until the saturation point was reached. Afterwards, the interviews were transcribed and imported to NVivo 12 plus, which was used to conduct a thematic analysis of the interviews. The major findings of the research revealed that entrepreneurs face many challenges with regards to the access and availability of financial support in Pakistan. Additionally, according to the respondents, the entrepreneurial journey in Pakistan is laden with challenges and has minimum drivers (opportunities available to the entrepreneurs). The respondents also expressed a lack of awareness and downright distrust of the government-sponsored financial support schemes.

Published: August 2022

The effect of employee perception of despotic leadership on employee job performance is an active area of research. The current study used the conservation of resource (COR) theory to investigate the mediating impact of employee work engagement and the moderating role of social climate of friendship groups. For this purpose, a proportionate sampling technique was used. Data was collected from 423 employees of pharmaceutical companies listed on Pakistan Stock Exchange (PSX) by utilizing a dyad approach with predictors (self-reports) and employees’ performance (supervisor-reports). The hypotheses were tested through Hayes Process (2012) and regression analysis. The study results showed that employee perception of despotic leadership is inversely associated with employee job performance and work engagement. Furthermore, this study identified that the impact of this association decreases under the conditions created by the social climate of strong friendship groups. This research explores this broad area and adds to the body of knowledge on dark leadership. The findings of the study have significance for both theory and organizational practice.

Published: August 2022

Despite the South African government's desire to encourage economic growth via SME growth, attempts to ameliorate the difficulties encountered by SMEs are often hindered by a lack of resources, one of which is business incubation. This paper employs a descriptive literature review to declutter the varying concerns of SME growth and development from the narratives around the role of business incubators (BIs) and the government. This, we believe, would provide clarity on the challenges faced by SMEs development in South Africa by filtering the roles of both BIs and the government. Descriptive literature review as a qualitative technique helps to reveal an interpretable pattern in the current literature and was thus employed in this study. Even while the literature points to the importance of SMEs in economic growth, their volatility makes them an unreliable partner for the South African government currently. This is because the literature suggests that the government is failing them in one way or the other through limited and failed support systems. Because of their excessive reliance on government funding, BIs cannot help SMEs as they should because of the lack of funding. Consequently, one might argue that the & quot; law of unintended consequences," or the unexpected repercussions of government policies and actions/inactions, hinder South Africa's government from achieving its objectives. We flag some implications and future research directions in our closing arguments.

The investigation into the impact of conflict on the modern approach of employee agility as well as employees’ perceived job performance seems to be a critical topic that has not relatively been touched on yet. The present study aims to look at the influence of conflict on employees’ agility and employee’s perceived job performance. This research divides conflict into two separate dimensions as task and relationship conflict to investigate the impact of each on agility and job performance. The data is collected by employing a self-structured questionnaire using 23 items and a 5-point Likert scale from the employees of a hygiene and sanitation company in Cameroon. The proposed model is examined via PLS-SEM. Overall, the study reveals that there is a negative coefficient in the relationship between relationship conflict and employee’s agility; a significant positive relationship between task conflict and employee agility; and a positive significant relationship between employee’s agility and employee perceived job performance. The generated results validate that task conflict is vital and welcome to workers; thus, managers are expected not to blindly avoid conflicts. The consequence of a constructive conflict can be employee agility which in itself will lead to a high level of job performance.

Published: August 2022

The current study claims that the Human Resource Information System (HRIS) Use Behavior, plays a salient role in utilizing the information technology as intended. Thus, organizations investing in information technology are in dire requirement of developing and implementing the effective interventions. The purpose of this is to optimize information technology adoption and its maximum usage among the HRIS users. The existing knowledge base in HRIS Use Behavior hardly addresses the relationship of Charismatic Leadership and Technology Self-Efficacy in the Unified Theory of Acceptance and Use of Technology (UTAUT). The current study has developed an ‘integrative conceptual model’ contributing a theoretical extension of the UTAUT model, which fills he identified theoretical gaps, grounded on UTAUT, Charismatic Leadership theory, and the Social Cognitive Theory. The salient feature of this study is that it conceptualizes and introduces two constructs: 1) Technology Self-Efficacy and 2) Charismatic Leadership, in extending a validated information system Use Behavior or ‘explanatory model’ as a theoretical contribution. This concept paper argues that the Charismatic Leadership and Technology Self-Efficacy have a positive relationship among the UTAUT model's HRIS Use Behavior-related variables. However, it can be integrated towards arriving at a ‘coherent conceptual model’ to be researched and validated. This particular study has developed a ‘coherent conceptual framework’ in studying the phenomenon of HRIS Use Behavior. Furthermore, it studies the role of Charismatic Leadership and Technology Self-Efficacy in affecting the psychological aspect of the end users of a Human Resource Information System (HRIS)

The present study examines the positive impact of ethical leadership on whistleblowing. The study further investigates the role of job security and affective commitment as moderators on the relationship between ethical leadership and whistleblowing. This study examined the fundamental moderating mechanism, which is unique because no such mechanism has been investigated in previous research. A cross-sectional representative sample of 285 Federal Government employees from various Ministries/Divisions and the Benazir Income Support Programme, a corporate body and a renowned social safety net under the Federal Government of Pakistan, was collected. Of the 285 questionnaires, only 241 were deemed useable and were analyzed. A statistical analysis was carried out through correlation, descriptive, and moderated regression analysis. The results supported the first three hypotheses that ethical leadership and whistleblowing had a positive relationship. Furthermore, job security moderated the positive relationship between ethical leadership and whistleblowing, such that the relationship is stronger for employees with high job security and weaker for employees with low job security. Affective commitment also moderated the relationship directly meaning that the relationship is stronger when the affective commitment is strong and weaker when it is weak. Discussion, implications, limitations, and future directions have been suggested in accordance with the results of the study.

Schools are educative institution whose function is for building, fostering and improving the qua-lity of human resources. The application of clean and healthy living behavior is very important to maintain the health of school aged children. One example of the application of that behavior is hand washing, nonetheless there are many schools that lack of hand washing facilities. Beside hand washing, hand sanitizer which has two types, i.e. gel and spray, is a material that can be used to reduce hand microbe number. The education on how to use the sanitizer among ele-mentary school students may be through their peer “little doctor”. This study was aimed to know the effect of information dissemination about hand sanitizer by the little doctor towards the de-crease of hand microbe number of SDN Demakijo I students in Gamping, Sleman. The study was an experiment which followed pre test and post test only design. There were 70 respon-dents who were sampled from grade III, IV and V of the school, and then they were divided into two groups so that each type of hand sanitizer had 35 respondents. The paired t-test yielded p values < 0,001 for both types of sanitizer, and therefore it was concluded that the two types significantly capable in reducing the microbe number. Furthermore, the independent t-test yield-ed a p value < 0,,001 which is meant that the microbe reduction between the two types was significantly different. Spray hand sanitizer was more effective because it was able to reduce 89,54 % of the microbe compared with only 69,90 % of the gel type.

Knowledge and practice about waste management among housewives in Cetan Village were low, i.e. 40 % did not know about waste and the health impact from bad waste management, and 65,6 % knew that waste can only be managed by burning it and throwing onto yards and rivers, 78 % had behavior of mixing and burning organic and inorganic wastes, and 22 % had habituality of throwing the mixed wastes onto vacant yards and rivers. This study was aimed to know the influence of demonstration method for increasing the knowledge and practice of the housewives about domestic waste management. The research method used was quasi experiment with non-equivalent control group design. 40 respondents for the experiment group and other 40 respondents for the control group were selected by using purposive sampling method. The data was analyzed by using Anova multivariate test at 95 % confidence level. A nine itemed questionnaire which had been tested for its validity (p<0,05) and realibility (p=0,711) was administered to measure the knowledge level, meanwhile a checklist with five items was used to measured the level of practice (the corresponding validity reliability tests yielded p values of <0,05 and 0,701, respectively). The results of the research showed that, in general, the elucidationwith demonstration method influenced the increase of knowledge and practice among the housewives (p=0,037). However, in specific, only the practice aspect was observed increase significantly (p=0,017), meanwhile the knowledge aspects was not (p=0,428). It can be concluded that demonstration method is more effective for increasing the practice of housewives in domestic waste management.

Rafflesia patma Blume is placed as one of the CRB2c endangered status. It refers to the taxon who face the highest extinction in the short periode of time. The flower scarce is caused by a live factor of R. patma that need specific habitats such as physical and biotic factors. The habitats and population of R. patma will be charge on fluctuation due to the higher human activities and nature's changes. The study on population of R. patma in CA Pananjung Pangandaran (CAPP) was conducted. The results indicated that R. patma founded 312 individuals which distributed in 6 locations. This condition indicated that CAPP is suitable from R. patma.

Reproduction Habits (Flowering, Fruitting and germination) of Phaleria spp. at Bogor Botanical Garden, One Step Towards Its Conservation. Phaleria is potensial genus for ornamental and medicinal plant. This genus consist of 38 species in the world, of which distributed in Indonesia particularly in Sulawesi and Papua, three of them are conserved at Bogor Botanical Garden. In some countries, the plants have been used for medical treatments, craft, food sources, and ornamental plant. As a preliminary research for the next conservation effort, an evaluating of flowering/fruitting season and generation growth of Phaleria collection was studied. The reason of the research, there is no many seed on the garden grow as a seedling. So the germination studied on the nuresry. The result show tahat January to March as a peak season for flowering/fruitting of Phaleria. The germination rate is very fantastic, 10% of seed have been germinated one day after planted. The result also shows that the fallen seed have germinated higher than picked seed. A thick manure on the land and low sunlight penetration might be the problems on  the garden for growing seedling of Phaleria.

This study explores the local wisdom in utilizing and maintaining the presence of N. ampullaria in Kerinci. Data collection through open-ended and deep interviews through participatory observation methods. Data analysis and presentation are delivered descriptively. Lemang is a compulsory item to be served in traditional ceremonies of kenduri sko. There are two types of lemang in Kerinci, lemang bamboo and lemang kancung beruk. The latter is found only during the kenduri sko tradition in Kecamatan Gunung Raya and Bukit Kerman. Therefore, the existence of lemang kancung beruk in these two sub-districts has become obligatory and has no other comparable substitute. In Gunung Raya and Bukit Kerman, the Kenduri sko is held four times a year. The need for N. ampullaria for kenduri sko in these two sub-districts is enormous. For the event, each household needs at least 500 to 2000 pitchers of N. ampullaria. The people of Kerinci harvest N. ampullaria directly from the wild to fulfill the need. The population of N. ampullaria that still survives in its natural habitat is evidence of the success of the local community in maintaining the existence of N. ampullaria in Kerinci. Method and schedule arrangements can allow the population of N. ampullaria to recover.
