EFFECT OF PUBLIC SERVICE MOTIVATION ON JOB PERFORMANCE: A LITERATURE REVIEW
Authors: OFOBRUKU GOODLUCK
Published: September 2024

Public service motivation is gaining substantial empirical support as a valuable variable in public sector organizations. Several studies have observed organizationally desirable relationship between public service motivation and several employees’ attitudes and behaviour. However, the various accounts on public service motivation spread over several journal articles, thereby lacking practical appeal. This paper aimed at filling this gap as it reviews studies on public service motivation and job performance. The purpose of the review is to identify and put together in a single paper the dominant implication of public service motivation on job performance as indicated in the literature This systematic compilation would plausibly make the observed dominant findings (that is, positive influence of public service motivation on performance) appealing and convincing for organizational practitioners to adopt and apply. Person-environment fit theory offers theoretical support for the dominant pattern of relationships that is revealed in the reviewed empirical studies.
THE BLOOD AND ALCHEMY OF THE TRANSFORMATION OF THE BRAZILIAN PEOPLE: THE BLOOD OF THE ANCESTORS, THE BLOOD OF CHILDBIRTH AND THE BLOOD OF COMMUNION
Authors: BERGMANN CRISTIANE , BOECHAT WALTER
Published: September 2024

This work, based on Carl Gustav Jung's depth psychology, looks at blood as an alchemical element of the body and soul that connects us to our roots, to our ancestors, to the original peoples, connecting us both as individuals and as a Brazilian people. By delving into the symbolism of blood and understanding its relationship with the formation and identity of the Brazilian people, some memories will be pointed out regarding the history of the Brazilian people, from the beginning of the colonization process by the white European people, as well as how the Brazilian people were born, the quality of the bonds and relationships between the indigenous original peoples and the Portuguese from the 16th century to the present day, relating some stories that reveal, today, the conflicts over the demarcation of lands and the protection of indigenous peoples in Brazil. Blood, as a living element that constitutes and connects us, will also be approached from the point of view of indigenous mythology, through the narrative of the story of Kamé and Kairú, of the meeting between the Sun and the Moon from the point of view of the Kaingang people. For the alchemical integration of these processes between blood and the individual and collective psyche, the symbolism of blood in the chalice, the blood of communion, will be the alchemical vessel for combining the parts studied here, in order to create awareness and transformation through the process of individuation.

The research described in the article concerns advanced methods of creating composite materials for drill bits used in extreme conditions of deep wells. The main attention is paid to development of multicomponent mixtures that ensure uniform distribution of powders of tungsten carbide, cobalt, chromium diboride and diamond. This is achieved through careful selection of particle size and proportions, which is critically important to ensure high strength and wear resistance of final materials. The Spark Plasma Sintering (SPS) method was chosen for the production of samples of carbide matrices and composite diamond-containing materials because of its ability to provide high density and uniformity of the material. SPS allows temperature and pressure control during sintering process, which contributes to the formation of materials with optimal physical properties. The article also discusses in detail design parameters of the diamond bit, including the choice of grain size of diamond powder and other components. These meters have been optimized to max-imize drilling efficiency and extend tool life. The diamond powders used in study were obtained from De Beers, South Africa and are characterized by high quality and uniformity. The results presented in the article can have a significant impact on future production of drilling tools, offering new approaches to choice of materials and methods of their processing, which ultimately can lead lower drilling costs and increased process safety. These innovations can also contribute to more efficient development of new fields, which is of great importance for the energy industry and the mining industry.

In producing wells, complete wetting often occurs, during which most of the oil reserves in them remain unproductive. This feature is typical for various fields, as well as for the fields of Kazakhstan. In this case, the most reliable way to increase oil recovery is to limit oil recovery through the use of modern technologies and chemicals. This article discusses the type of technology that allows to increase the efficiency of processing the bottom of the well – the use of sedimentary gel-forming compounds – SRFC the basis of the SRFC technology is to reduce the permeability of the flushed zones in the bottom of the formation and reduce the degree of its heterogeneity. The effect of these formulations is based on the formation of an insoluble precipitate and a gel polymer in the pore space in the lower part of the layer, the specified precipitate and gel block or reduce the permeability of the intervals washed. In the article, as a result of experimental studies, an assessment of the physico-chemical properties of gel-forming compositions was carried out using statistical methods for processing values and analyzing data, in connection with which the rheological properties of sedimentation compositions were simulated, taking into account the composition and average concentrations of various components (polymer, alkali).

Published: September 2024

In dye-sensitized solar cells (DSSCs), light is absorbed by the sensitized dye. When light strikes the dye molecule, it absorbs photons and becomes excited to a higher energy state. This excited state allows the dye molecule to inject an electron into the conduction band of the semiconductor, generating an electric current. The selection of dye properties is very significant, as it can help to improve the performance of DSSCs. However, achieving an identical output current-voltage characteristic from the same batch of plants or fruits used as dyes is very difficult. Furthermore, improving the electrical performance, such as short-circuit current density and efficiency, of fabricated dye-sensitized solar cells is critical, as many experimental factors need to be considered. Therefore, to minimize the extra use of material resources due to the risk of unsuccessful fabrications and to obtain better performance ideally, conducting simulation-based studies is important to optimize the performance of DSSCs. The free software General-Purpose Photovoltaic Device Model (GPVDM) is a promising and interesting tool due to its free license and easy accessibility through a graphical interface for simulating optoelectronic devices, including OLEDs, OFETs, and various types of solar cells. This paper considers GPVDM, a 3-D photovoltaic device model, to simulate the proposed structure with different samples of chlorophyll dye for DSSC performance. The paper aims to characterize the high current density-voltage (J-V) of chlorophyll-based DSSCs and identify suitable photovoltaic simulation software for running simulations of chlorophyll-based DSSCs. Finally, the outcomes are compared with experimental data reported in various literature sources. The results show an enhanced short-circuit current density (Jsc) of 0.3556 mA cm-2 for Cordyline fruticose leaves (Chl E), which is the highest among the other dyes tested. The value of simulated short-circuit current density (Jsc) is slightly different from the experimented result Jsc reported in the published paper. In conclusion, GPVDM can be considered suitable for modeling DSSCs.

Published: September 2024

This study examined two solar panels with a high producing capacity of 250 W for performance enhancement utilizing several types of paraffin wax (RT57, RT61, and RT68) connected to the panel's rear surface. Two solar panels (one reference and one combined with PCM; PV-PCM) are used for outdoor tests. The current implementation is made with three types of PCM with a fixed thickness (3 cm) and with different inclination angles of 10°, 20°, 30°, and 40°. According to the results, the PV panels' tops had the maximum temperature spread, while their bottoms showed the lowest variation in temperature. At an inclination angle of 10◦, the temperature on the upper side of the plate is 18.8% higher than the lower side, 14.3%, and 12.2% for PCM1, PCM2, and PCM3, respectively. There is also an improved electrical power output of 16.8% for the PV-PCM panel with 3 cm PCM thickness over the reference panel (PV) with a tilt angle of 40◦. Relatedly, raising the inclination angle from 10◦ to 40◦ improves the Energy efficiency of PV-PCM with a thickness of 3 cm PCM by 10.4%. Finally, using 3 cm thick PCM improves the Energy efficiency of the PV-PCM panel by 17.4% compared to PV with an inclination angle of 30◦.
Simulating the Rising Air Bubbles Stream through Heavy Fuel Oil Residue Bubble Column Reactor using COMSOL
Authors: Ali Al-Naqqash Hussein Reda Muhammad , Alhwayzee Mohammed , Lafta Rashid Farhan
Published: September 2024

Several industrial operations rely on the rise of air bubbles through heavy fuel oil residue (HFOr), including oil recovery and wastewater treatment. In order to increase efficiency and decrease expenses, it is necessary to understand the peculiarities of this process. With the help of COMSOL Multiphysics, we numerically simulate the ascent of a single air bubble via HFOr in this article. The dimensions of the container used in the simulations were (100) mm in diameter and (200) mm in height, with an air bubble diameter of 4.5 mm. For an air bubble ascending through an HFOr column, the predicted numerical outcomes are contrasted with nine experimental versions. As the bubble rose higher, the region with the greatest number of vortices was located on its side. The remaining vortex is contained inside the bubble. In addition, since drag decreases the flow, a lighter fluid usually exhibits a region of strong vortex and low pressure. Because of the oscillation effect, the results reveal that the rising velocity initially rises and then gradually falls between 0.6 and 0.65 s. The air bubbles' wavy motion is caused by the high fluid density, which becomes worse as the air velocity gets higher. The values of the drag coefficient rise sharply with decreasing air extrusion speed. It turns out that the height of the fluid has an inverse relationship with the pressure.

The effect of discharge cooling using condensate water from the evaporator on the performance of an air conditioner has been experimentally investigated. Instead of laboratory testing, the air conditioner was tested under real conditions, as is generally an AC unit installed in a room. The indoor unit was installed inside the room at a height of 2.6 m from the floor, while the outdoor unit was installed outside at floor level. In this research, the air conditioner was tested under two conditions, i.e., normal condition without discharge cooling and modified condition in which the condensate from the evaporator was flown and dripped to the discharge pipe. The use of discharge cooling could decrease suction and discharge pressure, as well as suction and discharge temperature. It also slightly decreases supply air temperature. Better performance of the air conditioner with the use of discharge cooling was shown by the decrease of power consumption by 3.5% and increase of cooling capacity by 2.45%. As a result, the coefficient of performance (COP) increases by 6.31%.

This research focuses on the development of instant kombucha drink and kombucha ice cream using spray drying techniques. Kombucha, a fermented tea known for its health benefits, is processed to halt alcohol production and enhance its usability in various forms. The study utilized three treatment methods to ferment kombucha: Cold shock at ≤ 4°C for 5 days, pasteurization at 72°C for 20 mins and yeast removal using a coffee filter, alongside a standard fermentation control. The spray drying process was applied to kombucha from these treatments to produce instant kombucha powder. The physicochemical properties, nutritional quality and microbial safety of the resulting powder were evaluated. The best results were obtained from pasteurization, yielding a powder with low alcohol content (0.13 % w/w), desirable physicochemical properties (4.70 total dissolved solids, 3.10 pH, 0.2177 titratable acidity) and microbial safety (< 1 CFU/ml). Subsequently, instant kombucha powder was utilized to develop two new products: Instant kombucha drink and kombucha ice cream. The instant drink reconstituted well with water, maintaining the original kombucha's flavour profile and health benefits. The kombucha ice cream was formulated to preserve the bioactive compounds and probiotics, offering a novel health-promoting dessert option. Sensory evaluations indicated high consumer acceptance for both products, with the instant drink and ice cream scoring well on taste, texture and overall satisfaction. The innovative use of spray drying to produce instant kombucha powder and its application in diverse products highlights the potential for expanding kombucha’s market presence while retaining its health benefits.

Solar cells, also known as photovoltaic cells, convert light energy into electrical energy through the photovoltaic effect. Integrating a thermoelectric generator into a photovoltaic system enhances power output and efficiency by utilizing waste heat. Concentrators are employed to further improve solar panel efficiency. This study aims to develop a solar thermoelectric generator (STEG) with a concentrating system that includes a heat sink cooling system, thermoelectric generator, and concentrator. Three conditions will be tested to observe the power output of each solar module: PV standalone, STEG with a heat sink, and STEG with a heat sink and concentrator. The efficiency appears to improve from 9.21% for PV standalone to 10.11% for STEG with a heat sink and 10.23% for STEG with a concentrating system. The results of these studies aim to establish a benchmark for enhancing the efficiency of future STEG systems.

Mobility is the capability of one to get to another place. Vision is defined as the faculty and power of seeing. As technology develops and grows, several devices and tools have aided those with mobility issues or impairment and those who are visually impaired. For those who are visually impaired, the traditional aid has been the white cane for a long time which only helps them navigate their way and detect obstacles without providing physical support. While those with mobility issues use a walking stick which does not help them in detecting surrounding obstacles. For those with both mobility issues and visual impairment, this becomes a problem as it is uncommon for a gadget or aid to tackle both these issues at once. The Smart Guide Cane is specially designed for this group of people with both issues. It can also help those with any of the two issues as it has many features that will allow them to be more confident in their movement, improving the quality of life for the disabled. Many steps have been taken in developing the Smart Guide Cane. A program was coded and simulated together with the circuit to ensure the functionality of the program. Then, the physical prototype was created, using Arduino UNO, HC-SR04 (ultrasonic sensor), MPU6050 (fall detector), TTP223 (touch sensor), vibration motor and buzzer as its main components. Tests have been done using this prototype circuit to demonstrate the feasibility and functionality of the Smart Guide Cane. From the prototyping and testing, it can be seen that all the components would function as intended in the Smart Guide Cane.
Imprints of the Local Bubble and Dust Complexity on Polarized Dust Emission

Using 3D dust maps and Planck polarized dust emission data, we investigate the influence of the 3D geometry of the nearby interstellar medium (ISM) on the statistics of the dust polarization on large (

80
′

) scales. We test recent models that assume that the magnetic field probed by the polarized dust emission is preferentially tangential to the Local Bubble wall, but we do not find an imprint of the Local Bubble geometry on the dust polarization fraction. We also test the hypothesis that the complexity of the 3D dust distribution drives some of the measured variation of the dust polarization fraction. We compare sight lines with similar total column densities and find that, on average, the dust polarization fraction decreases when the dust column is substantially distributed among multiple components at different distances. Conversely, the dust polarization fraction is higher for sight lines where the dust is more concentrated in 3D space. This finding is statistically significant for the dust within 1.25 kpc, but the effect disappears if we only consider dust within 270 pc. In conclusion, we find that the extended 3D dust distribution, rather than solely the dust associated with the Local Bubble, plays a role in determining the observed dust polarization fraction at 80′. This conclusion is consistent with a simple analytical prediction and remains robust under various modifications to the analysis. These results illuminate the relationship between the 3D geometry of the ISM and tracers of the interstellar magnetic field. We discuss implications for our understanding of the polarized dust foreground to the cosmic microwave background.
