In the few decades, pepper production in Indonesia retains its position as one of the biggest producers in the world. However, pepper production in the province goes down. Consequently, the income of pepper farmers reduces. Understanding the farmers' demographic and their perception of the technology acceptance model will help policymakers provide the best empowerment program and agricultural support program to uplift their welfare. The study aims to understand the socio-economic profile and the perception of pepper farmers towards the technology acceptance model using information technology in pepper farming activity. The data collection process was conducted from August to November 2019. Structured questionnaires and face-to-face data collection methods were applied to earn the primary data from 100 pepper smallholders in Bangka Tengah and Bangka Selatan, Bangka Belitung Island Province. Descriptive analysis was used to identify the respondents' profiles and explain their skills and awareness to adopt information technology in their farming activity. The study revealed that most of the pepper farmers were in the average age of 45 years old, held elementary school level, received income of about 5.7 million, was experienced farmers with 20 years of pepper farming activity, and had about 2.1 – 5 ha of land area. The majority of the pepper smallholders offered low scores to the proportion of perceived usefulness and perceived ease of use.

Published: November 2021

Surface plasmon resonance (SPR) is a highly sensitive method for monitoring changes in the optical characteristics that are near the sensor surface. It can be stimulated by an evanescent field that comes from the total internal reflection of the backside of the sensor surface in the Otto setup. In this setup, SPR can be used to build a simulation model at different thicknesses of titanium oxide (TiO2) (dTiO2 = 50 nm) and silver (Ag) (dAg = 10–80 nm) layers, which are deposited on the semicircular glass prism D-ZLAF50 by using water as a sensing medium. The surface plasmon resonance angle (θSPR) properties were calculated; SPR was not observed in the ultraviolet region (300 nm) or in the infrared region at 800 nm, but appeared strongly in the visible region at 600 and 700 nm and in the infrared region (900 and 1000 nm). The best sensitivity (S = 140) can be observed in the visible region, where the values of SPR dip length (Ld) and full-width half maximum (FWHM) are very good at silver layer thicknesses 40–60 nm; therefore, the proposed sensor can be used in the visible and infrared regions at the wavelengths 600, 700, 900, and 1000 nm.

Authors: Alsaeed Maha
Published: November 2021

There is a growing interest in the flipped design model in K–12 mathematics classrooms, as it has been shown to have a positive influence on learning. This study aims to help improve students’ learning of irrational numbers using the flipped design model. This study outlines four design elements of the flipped environment that are shown to increase student engagement. Two eighth-grade classes (n = 60) were examined using a quasi-experimental research design in terms of students’ mathematical achievements and engagement levels. Each class was tested using a different instructional approach: traditional learning or flipped learning. The results indicated that the eighth-grade students in the flipped learning model group demonstrated an overall medium to a slightly high level of cognitive, behavioral, emotional, and social engagement, as well as a slightly high performance with irrational numbers. Also, when comparing the flipped and traditional learning environments, the results revealed that neither group was significantly different in terms of mathematics performance or engagement. Several recommendations and implications are discussed for teaching complex mathematics concepts via a flipped learning environment, including enriching the learning environment with student collaboration, social and emotional support, and problem solving.

Published: November 2021

The energy crisis and ecological disasters have become a critical problem in recent decades. The human activities through industrial operations increase emissions and other pollutant particulates in the world as a result of steady patronage on fossil feedstock. Several experiments were performed to identify an alternative fuel meeting the rising energy demand. Biomass (bio-fuel) has recently been developed as an economical fuel, environmentally friendly resource, renewable and sustainable fuel. Approximately 350 crop plants were evaluated and some of them could be considered as suitable alternative diesel engine fuels. To increase the bio-fuel quantity globally, apart from crops, other biomaterial sources are considered potential in biofuel production. It was shown that the properties of biofuel combustion are identical to fossil. In the experimental combustion of biodiesel blends, higher ignition pressure and temperature, shorter ignition delay, and higher peak release were recorded. This paper is a literature review on the need for biofuels as a global renewable fuel resource and aims to explain the characteristics of combustion and pollutant formation in the application of biofuels. The study also stated the resources, the use of biogas and its emission impact in flameless combustion mode. With holistic adoption of biomass source of fuel together with the modern conversion techniques, issues from fuel emissions will be mitigated.

Published: November 2021

Renewable energy is a reliable solution for addressing global warming and fossil fuel depletion issues. Due to the abundance of biomass resources, such as palm oil wastes, which are currently underutilised, this is an opportunity for Malaysia to seize and implement this renewable energy solution for power generation. Palm oil mill wastes, such as empty fruit bunch (EFB), palm mesocarp fibre (PMF), and palm kernel shell (PKS), are worth to be investigated as a possible feedstock for combustion in thermal power plants. Co-combustion or co-firing of biomass in coal-fired thermal power plants offers a significant potential to reduce harmful emissions and represents a low cost and low-risk method. This paper aims to review and compare existing biomass thermal combustion technologies globally to evaluate the potential of utilising palm oil waste with coal. Before undergoing various pretreatment options, it is necessary to understand the feedstock characteristics for thermal power plant combustion. It is recommended to implement the combustion of palm oil wastes with coal in Malaysia to reduce harmful pollution. Based on the findings, Malaysia appears to be on the right track to optimise the use of palm oil wastes for electricity generation. The enhanced usage will reduce the negative impact of greenhouse gas (GHG) emissions.

The use of solar thermal technologies has shown great prospects towards solar energy conversion into more useful forms of energy and has increasingly expanded solar thermal technology applications. However, the inability to properly store the excess solar energies during peak hours and demands have limited many of their applications. The integration of thermal energy storage (TES) systems with thermal technologies have increased the solar thermal technology performance but the poor thermal characteristics exhibited by phase change materials (PCM) limited the system overall performance. The enhancement of PCM properties by nonadditive have shown increased material performance in TES application and thereby extending the use of solar thermal technology application. Given this narrative and identifies literature gaps, the present study investigated experimentally the enhancement of paraffin PCM using nonadditive metallic of different types and concentrations and analysed their thermal behaviours. The results showed that Cu/paraffin PCM nanocomposites had good thermal reliability in proposed applications even after 150 thermal cycles under different temperatures. Moreover, thermal conductivity was improved significantly as an enhancement of 39% was reported when adding 2.5% of Cu nanoparticles. While specific heat and thermal diffusivity has been enhanced by 16% and 9%, respectively compared to pure paraffin. The obtained results were compared with different theoretical models such as Maxwell mode, Hamilton Crossover model, Jeffery model, and Bruggeman model. The calculated values show a good agreement with experimental ones. As a result, the prepared Cu/Paraffin nanocomposite PCM shows significant promise in thermal energy storage application due to its favourable phase change temperature, comparatively large latent heat, enhanced thermal conductivity and high thermal reliability and conversion. The proposed nanocomposite PCM can be used in many applications such as building materials to reduce interior temperature swings, enhance thermal comfort, and conserve electricity consumption.

Published: November 2021

Solar energy reaching Earth can be used as promising renewable energy to overcome the challenges of steam generation processes. Solar concentrators suffer from fine adjustment of solar radiation concentration and high investment cost. Therefore, multi-configuration receivers named the cylindrical cavity receiver, helical receiver, and the absorber-evaporator-tank have been manufactured from the coiled copper tube and brass plates, respectively. Then, they are tested and compared to improve the performance of steam generators. The performance of the absorber-evaporator-tank receiver has been compared with the cylindrical cavity receiver and helical receiver for a period from 10 am to 12 pm. The present investigation shows that the boiling point of water increasing when the pressure of generated steam increases particularly inside the coiled tube, which affects the dryness fraction of the generated steam. The present results show that the efficiency of the absorber-evaporator-tank is greater than the cylindrical cavity and helical receivers for the tested period. It is found that the thermal efficiency for the absorber-evaporator-tank doubles at noon, which indicates an effective solar receiver for generating steam.

The production of oil and natural gas contributes to a significant amount of revenue generation in Malaysia thereby strengthening the country’s economy. The flow assurance industry is faced with impediments during smooth operation of the transmission pipeline in which gas hydrate formation is the most important. It affects the normal operation of the pipeline by plugging it. Under high pressure and low temperature conditions, gas hydrate is a crystalline structure consisting of a network of hydrogen bonds between host molecules of water and guest molecules of the incoming gases. Industry uses different types of chemical inhibitors in pipeline to suppress hydrate formation. To overcome this problem, machine learning algorithm has been introduced as part of risk management strategies. The objective of this paper is to utilize Machine Learning (ML) model which is Gaussian Process Regression (GPR). GPR is a new approach being applied to mitigate the growth of gas hydrate. The input parameters used are concentration and pressure of Carbon Dioxide (CO2) and Methane (CH4) gas hydrates whereas the output parameter is the Average Depression Temperature (ADT). The values for the parameter are taken from available data sets that enable GPR to predict the results accurately in terms of Coefficient of Determination, R2 and Mean Squared Error, MSE. The outcome from the research showed that GPR model provided with highest R2 value for training and testing data of 97.25% and 96.71%, respectively. MSE value for GPR was also found to be lowest for training and testing data of 0.019 and 0.023, respectively.

Published: November 2021

Carreau fluid flows past a stretching cylinder is elucidated in the present study. The transformed self-similarity and dimensionless boundary layer equations are solved by using the Homotopy analysis method. A convergence study of the method is illustrated explicitly. Series solutions of the highly nonlinear differential equations are computed and it is very efficient in demonstrating the characteristic of the Carreau fluid. Validation of the series solutions is achieved via comparing with earlier published results. Those results are obtained by using the Keller-Box method. The effects of the Weissenberg number and curvature parameter on the velocity profiles are discussed by graphs and tabular. The velocity curves have shown different behavior in and for an increase of the Weissenberg number. Further, the curvature parameter K does increase the velocity profiles.

Published: November 2021

The Kelvin-Helmholtz instability (KHI) occurs at the interface amongst two fluids, which are in relative motion with a common boundary. The growth rate of waves occurs whenever the relative velocity is greater as compared with the critical relative velocity. In the present paper, the influence of boundary roughness on KHI under the impact magnetic field in a couple-stress fluid layer bounded by a rigid surface at the lower side and upper side by a fluid saturated porous layer. Using suitable surface and boundary conditions, we have derived the dispersion relation and results are depicted graphically. As observed in presence of sharp interface, magnetic field exhibits stabilizing effect however, destabilizing effect is shown by the buoyancy force on KHI. Also, noted that the growth rate of interface reduces, as there is a rise in roughness parameter value.

Published: November 2021

The annual increase in energy demand has led to an increase in greenhouse gas emissions, in particular CO2 emissions from the power generation industry. Carbon Capture and Utilization are technologies applied to capture CO2 gases and transform the gases into a different energy source. The adsorption technology to capture CO2 gases was chosen due to the minimum energy consumption and low costs required for an industrial application for sustainability. Metal-Organic Framework (MOF) has a reasonably high CO2 adsorption capability. It has been applied as an adsorbent for capturing and storing CO2. In this study, a comparison of CFD simulation with experimental CO2 and methane adsorption values in solid adsorbent beds containing MOF-5 at various temperatures was presented. The simulation was performed using 2D and 3D models from 0℃ at STP to 130℃ for CO2 and methane gas molecules. In addition, the isothermal and kinetic adsorption model was added to the simulations. This includes Single- and Dual-Site Langmuir adsorption isotherm and Linear Driving Force. The porous media model was then activated to imitate packed bed adsorbent and measured the pressure drop from the simulation. The results showed that the CO2 adsorption values of MOF-5 decrease as the adsorbent temperature increases. There was a decline of 0.002 mmol/g of adsorbed CO2 molecules per 10-kelvin difference. The CO2 adsorption value was 0.53 mmol/g at STP and 1.15 mmol/g for CH4 at STP. Both CO2 and CH4 adsorption were used to suggest optimal CO2 adsorption for the Pressure Swing Adsorption cycle.

Published: November 2021

The development of sophisticated unmanned aerial vehicles and wind turbines for daily activities has triggered the interest of researchers. However, understanding the flow phenomena is a strenuous task due to the complexity of the flow field. The engaging topic calls for more research at low Reynolds numbers. The computational investigations on a two-dimensional (2D) airfoil are presented in this paper. Numerical simulation of unsteady, laminar-turbulent flow around NACA 0015 airfoil was performed by using shear-stress transport (SST) model at relatively low Reynolds number (8.4 × 104 to 1.7 × 105) and moderate angles of attack (0 ≤ α ≤ 6). In general, on the suction side, with increasing Reynolds number and angles of attack, separation, and reattachment point shifts upstream and concurrently shrinking the size of the laminar bubble. However, On the pressure side, the laminar bubble is seen to move toward the trailing edge at the relatively same size as the angle of attack increases. Moreover, the variations in the angle of attack have more influence on the laminar separation bubble characteristics as compared to the Reynolds number. The reattachment points were barely observed for the range of the angles of attack studied. At very high angles of attack, it is recommended to simulate the flow field using large eddy simulation or direct numerical simulation since the flow is considered three-dimensional and detached from the surface thus forming a complex phenomenon.

This primary aim of this philosopher paper investigates the efficacy of the noise dissolving algorithm hinge on TTSD (Triple Threshold Statistical Detection) filter that has been originated since 2018 is one of the highest efficacy for dissolving RIIN (Random-Intensity Impulse Noise), exclusively at dense distribution. As a results, there are three essential contributions: the exhaustive explanation of the TTSD filter algorithm and its computation examples, the calculation simulation of noise apprehension correctness and overall comparative simulation of noise dissolving effectiveness. For TTSD filter, three malleable offsets that are the complementary requirement are employed in the TTSD filter that can adequately resolve the limitation of the antecedent noise dissolving algorithms. The first malleable offset is calculated for determining the noise characteristic of all elements by using the mathematical verification. Next, the second malleable offset is calculated for determining the another noise characteristic by using the normal distribution mathematical verification (the average value and standard deviation value). Later, the third malleable offset is calculated for determining the another noise characteristic by using the quartile mathematical verification (median value). In the simulation inquisition, the bountiful standard portraits that are desecrated by RIIN (Random Intensity Impulse Noise) with many dense distributions are experimented by noise dissolving algorithm hinge on TTSD in both noise segregation and noise dissolving perspective.
Repairing the M(other) and the Self Through the Creation of Art: Reading Hilda Doolittle’s HERmione in parallel with Ravel’s L’Enfant et les Sortilèges through Kleinian Lenses
Authors: Zorluoglu Emel
Published: November 2021

Hilda Doolittle, known as H.D., began to write prose fiction to surmount her traumas and see the way ahead again. H.D. composed varied autobiographical prose, among which her Madrigal Cycle Novels; Asphodel, HERmione, Paint it Today, and Bid me To live hold a pivotal place. Within the scope of this article, I will analyse HERmione in conjunction with Ravel’s opera L'Enfant et les Sortilèges which became the main subject of Melanie Klein’s paper on ‘infantile anxiety-situations reflected in a work of art and in the creative impulse’. Reading these two writings in tandem will help to clarify the connections that I draw between Klein’s ‘reparation’ concept and H.D.’s writing. The paper, read before the British Psychoanalytic Society in 1929, both elaborates upon Klein’s analysis regarding art production and introduces the term ‘reparation’ for the first time. Klein starts her analysis with Ravel’s opera, which focuses merely on the destructive fantasies of a six-year-old boy. Throughout the paper, Klein emphasises the significance of the reparation process in the handling of destructive fantasies and reads it within the good and bad mother dichotomy. Reading these two works together will shed insight into how- and why- did H.D. feel compelled to create this particular prose, as well as how similar destructive fantasies affected H.D.’s life and decisions paving the way to her being a writer. HERmione, though composed seven years after Asphodel, is a prelude to Asphodel and tells the story of H.D.’s years in Pennsylvania. This altered chronology indicates that there are emotional reasons for H.D. writing out of chronological order. There may be both editorial and psychoanalytical explanations for her choice to write about her adolescent years, 1906–1911, in particular, after writing on her war trauma and stillbirth, which happened around 1915. In this article, I endeavour not only to explain such explicit choices for a deconstructed chronologic linearity, a prominent feature of modernist forms, within a Kleinian psychoanalytic framework but also to analyse how the writing process contributed to H.D.’s own ‘reparation’ process.

Published: November 2021

Objective: To determine the ultrasonography (USG) values of median nerve cross-sectional area (MN-CSA) in pregnant women with and without diabetes mellitus (DM) to confirm carpal tunnel syndrome (CTS).

Methods: We prospectively studied pregnant women who have been diagnosed with pregestational type 1 and type 2 DM or gestational DM (GDM) due to positive GDM screening tests. One-step GDM screening (2 h - 75 g oral glucose tolerance test (OGTT)) was used at 24–28 weeks of gestation and diagnosis of GDM. MN was identified at the level of distal wrist crease in transverse sections with USG and maximal MN-CSA was calculated then, asked the patient complaints about her hand (paraesthesia, pain, numbness). The DM group was compared to the control group according to age, week of pregnancy, weight gain during pregnancy, MN-CSA, and presence of compliments.

Results: There were 107 DM pregnant women and 113 controls in the study group. The median value of MN-CSA was higher in the DM group than in the control group (p< 0,001). There was no difference between groups in terms of DM subgroups and insulin requirement. Hand pain is significantly frequent in the DM group than in controls. There has been a positive correlation between weight gain during pregnancy and MN-CSA (p =0,011; r=0,245).

Conclusion: USG can be a first-line diagnostic test for CTS in the diabetic pregnant population, as recommended for the general population before. Both pregnancy and DM are stated as risk factors for CTS, these patients must be evaluated more carefully about this issue and proper advices should be given to improve their life quality.

The contributions of the church to the social, economic and political growth of Ghana have been locally and internationally recognized. There is the need therefore, to subject the nature, prospects and challenges of the Christian advocacy of the church in Ghana to intellectual scrutiny to identify the issues that must be addressed for the church to perform its advocacy effectively. The study is an examination of the Christian advocacy ministry of the church in Ghana. It used both primary and secondary materials to generate data. Minutes and reports were examined for some primary information. The analysis of the available information points to the fact that the church must pay attention to niche management, capacity building of church leaders, enhance its public theology, creation of platforms for reflections, address the attacks on voices of wisdom, and direct attention to the role of the non-clergy in the advocacy ministry for its future Christian advocacy ministry. The study has added to knowledge in the disciplines of Church and Society and Public Theology.

The study investigated creativity and organisational efficiency in Nigerian private organisations to ascertain the extent to which workforce creativity enhances organisational efficiency. The quantitative methodology was employed and the research design was a cross-sectional survey. Stratified sampling was employed in selecting respondents from ten multinational companies across the six geopolitical zones in Nigeria. Research data were elicited from the respondents with the help of a structured questionnaire. The question response format of items addressing the research questions in the questionnaire were of the five-point Likert scale. The study used measurement items related to the extant literature for all the measures. Structural equation modeling was employed in data analysis with organisational efficiency serving as the latent variable while creativity constructs served as the measured variables. Results show that three out of the four constructs of creativity were significant predictors of creativity Thus, the competitive environment, social capital and technological factors influence creativity and that creativity predicts organisational efficiency.
Understanding the Effects of Systematics in Exoplanetary Atmospheric Retrievals
Authors: Ih Jegug , Kempton Eliza M.-R.
Published: November 2021

Retrieval of exoplanetary atmospheric properties from their transmission spectra commonly assumes that the errors in the data are Gaussian and independent. However, non-Gaussian noise can occur due to instrumental or stellar systematics and the merging of discrete data sets. We investigate the effect of correlated noise and constrain the potential biases incurred in the retrieved posteriors. We simulate multiple noise instances of synthetic data and perform retrievals to obtain statistics of the goodness of retrieval for varying noise models. We find that correlated noise allows for overfitting the spectrum, thereby yielding a better goodness of fit on average but degrading the overall accuracy of retrievals. In particular, correlated noise can manifest as an apparent non-Rayleigh slope in the optical range, leading to an incorrect estimate of cloud/haze parameters. We also find that higher precision causes correlated results to be further off from the input values in terms of estimated errors. Finally, we show that while correlated noise cannot be reliably distinguished with Hubble Space Telescope observations, inferring its presence and strength may be possible with James Webb Space Telescope observations. As such, we emphasize that caution must be taken in analyzing retrieved posteriors and that estimated parameter uncertainties are best understood as lower limits.

We report the discovery of SDSS J133725.26+395237.7 (hereafter SDSS J1337+3952), a double-lined white dwarf (WD+WD) binary identified in early data from the fifth-generation Sloan Digital Sky Survey (SDSS-V). The double-lined nature of the system enables us to fully determine its orbital and stellar parameters with follow-up Gemini spectroscopy and Swift UVOT ultraviolet fluxes. The system is nearby (d = 113 pc), and consists of a 0.51 M
⊙ primary and a 0.32 M
⊙ secondary. SDSS J1337+3952 is a powerful source of gravitational waves in the millihertz regime, and will be detectable by future space-based interferometers. Due to this gravitational wave emission, the binary orbit will shrink down to the point of interaction in ≈220 Myr. The inferred stellar masses indicate that SDSS J1337+3952 will likely not explode as a Type Ia supernova (SN Ia). Instead, the system will probably merge and evolve into a rapidly rotating helium star and could produce an underluminous thermonuclear supernova along the way. The continuing search for similar systems in SDSS-V will grow the statistical sample of double-degenerate binaries across parameter space, constraining models of binary evolution and SNe Ia.
Panspermia in a Milky Way–like Galaxy

Published: November 2021

We study the process of panspermia in Milky Way–like galaxies by modeling the probability of successful travel of organic compounds between stars harboring potentially habitable planets. To this end, we apply the modified habitability recipe of Gobat & Hong to a model galaxy from the McMaster Unbiased Galaxy Simulations suite of zoom-in cosmological simulations. We find that, unlike habitability, which only occupies a narrow dynamic range over the entire galaxy, the panspermia probability can vary by orders of magnitude between the inner (R, b = 1–4 kpc) and outer disk. However, only a small fraction of star particles have very large values for the panspermia probability and, consequently, the fraction of star particles where the panspermia process is more effective than prebiotic evolution is much lower than from naïve expectations based on the ratio between the panspermia probability and natural habitability.

Introduction: Human immunodeficiency virus (HIV) infection affects the lesbian, gay, bisexual, transvestite, and transsexual (LGBT) population. We aimed to identify the indidual vulnerability profile of the LGBT population ling with H/acquired immunodeficiency syndrome (AIDS) and correlate it with the treatment situation.

Methodology: This cross-sectional study included 510 LGBT people living with HIV (PLHIV)/AIDS who attended the Complex of Chronic Communicable Diseases of the municipality of São José do Rio Preto, São Paulo, Brazil, between 2008 and 2015.

Results: There was a predominance of indiduals who were white (70.2%), male (98.4%), single (87.1%), aged 25–44 years (70.0%), educated up to high school (47.7%), economically acte (91.2%), under treatment (80.8%), having CD4 > 350 cells/mm3 (77.1%), and having undetectable viral load (53.3%). HIV transmission was mainly sexual (97.0%) and most people used drugs (76.5%). There was a weak correlation between the variables ‘in treatment’ and acte occupation (r = 0.148, p = 0.001), single marital status (r = 0.128, p = 0.004), white race/colour (r = 0.117, p = 0.008), high school education (r = 0.111, p = 0.012), sexual transmission (r = 0.222, p = 0.000), drug use (r = 0.087, p = 0.049), and CD4 > 350 cells/mm3 (r = 0.118, p = 0.008); and strong correlation between the variables ‘in treatment’ and undetectable viral load (r = -0.937, p = 0.113).

Conclusions: The characteristics of the indidual vulnerability of LGBT people involve, among other aspects, issues of gender and social exclusion, a situation that is part of the daily life of PLHIV/AIDS in many scenarios and territories. This can be alleviated with a network of social and health support and effecte and efficient, protecte, attitudinal, and behavioural public policies.
