Consumer Behavior in Islamic Perspective: An Empirical Analysis
Authors: Farah Yasser
Published: September 2022

Pakistan is an Islamic country and the current paper is an attempt to investigate empirically whether Islamic consumer theory is being applied in this country or not. This study has used a set of questionnaires distributed to all general consumers working in different walks of life in the city of Lahore. Cronbach Alpha test is used to check the reliability and internal consistency of all variables in the questionnaire. In order to draw conclusions, percentage of respondents’ method has been used in SPSS. Results indicated that consumers in Pakistan follow Sharia rules moderately during consumption of goods and services, embrace Halal goods and services, and prefer to live a simple life, to some extent believe in wealth accumulation and believe that excessive accumulation of wealth induces them to lead an unnecessary luxurious life. Moreover, they frequently give donations to the needy, and somewhat consider the problems being faced by other consumers. They usually do not support a luxurious life when their siblings or neighbors are poor. They sometimes consider the life hereafter and control their wants during consumption of goods and services. Most of the people consider ethics in their consumption pattern and believe that absence of ethics is the major reason of defect of modern economics. Besides, most of the respondents are of the opinion that modern economics should include religious tools to get better outcomes. It is also concluded that they believe that social, moral and religious mechanisms are important with other economic programs and instruments in order to alleviate poverty. This study is important for the national and international producers, marketers and sellers who would like to sell their goods and services in Pakistan. Producers can produce goods and services by considering widespread Islamic consumption behavior in Pakistan in their production process. Marketers and sellers can attract mainstream consumers by depicting Islamic consumption pattern while marketing their products and services. To the best of my knowledge, no research in the past has been done to find out empirically Islamic consumer behavior for Pakistan.

This study determined the physio-chemical properties of the soil samples from selected hydrocarbon impacted sites in the Niger Delta region. Standard sampling and analytical methods were employed. The following physio-chemical parameters were analyzed; Sand, Silt, Clay, TOC (%), pH, EC (µs/cm), Av.P (mg/kg), Magnesium (mg/kg), Potassium (mg/kg), Sodium (mg/kg) and Calcium (mg/kg). Findings revealed that the physio-chemical properties of soil in the hydrocarbon impacted sites measured after the biostimulation remediation technique used in Oguta community, the enhanced land farming technique used in Omuwei community and the enhanced natural attenuation technique used in Oporoma community were within the permissible limit of WHO except conductivity (98.62-125.71) which require to be looked into. It further revealed that the physical and chemical properties of soil in selected impacted sites varied across the different sample stations. Based on these findings, it was concluded concluded that these variations observed in this study was due to the inherent environmental condition as at the time of sample collection. It is therefore recommended that relevant agencies should constantly check on the levels of these parameters using the WHO guidelines.

RISK ASSESSMENT OF HEAVY METAL CONTAMINATION IN APPLES SOLD WITHIN AWKA METROPOLIS IN ANAMBRA STATE NIGERIA
Authors: PRINCEWILL OKEKE ABUCHI
Published: September 2022

The intake of heavy metals through fruit consumption is a food safety problem that severely impacts the health of consumers; so information about food intake and heavy metal concentrations in food products is required to estimate the potential risk it poses to the health of the population. The aim of this study is to estimate the potential risks caused by heavy metals to human health from exposure to Cd, As, Pb and Hg through the intake of yellow and red apple considering the age group and gender. The concentration of each of the metals was quantified by spectrometry of atomic absorption (AAS) and the health risk indices such as health risk index (HRI), the hazard quotient (THQ) and the probability of carcinogenic risk (CR) through the consumption of apple were estimated. The concentrations of the metals analyzed in the apple samples shows the following decreasing order: Cd > Pb > As and Hg. The health risk assessments obtained from the samples of apples are located within the acceptable and tolerable limits; however, the increase in the intake of heavy metals through consumption of apples purchased from the study area may increase the health risk potential of consumers. For this reason, it is recommended to carry out studies on the concentration of heavy metals in various fruits products, mainly those of high demand, to guarantee food security of the population.

Nanoparticles are ultra-fine particles, thickness within a range of 100 nm in diameter. They are held responsible in enormous fields like diagnosis, bio-imaging, drug delivery, cancer therapy, environmental applications, biosensors, electronics, etc., due to their unique physicochemical properties. Among many noble metals, Palladium (Pd) is one such metal that has gained attention in this review. Plant-based biosynthesis has revealed the possibilities of synthesizing nanometric range palladium particles, their stabilization and impact of varying pH, temperature and concentration mostly on development and morphology with nanoparticles. the biosynthesized particles were determined using UV-Visible spectral analysis, FTIR, SEM, TEM - EDX as well as DLS technique whose findings were in support to the role of phytochemicals operating as reducing and stabilizing agents during the Pd (II) reduction to Pd(0). The antimicrobial activity of palladium nanoparticles (Pd NPs) synthesized from different plant extracts was also studied against various pathogens. The results showed the ability of Pd NPs to make the microbes susceptible by a clear zone of inhibition. Despite of all these experiments, the research demands further extensive study to bring out an exact mechanism for the process of Pd (II) reduction to Pd (0) and mode of action of Pd NPs against microbes.

Authors: GORJIAN BAHMAN , ARVAND EMAD
Published: September 2022

This study aimed to examine the relationship between the effects of the traditional method and PRAAT software to teach pronunciation to female high school students in Dehloran. The design of the research was a descriptive and comparison group design to interpret the phenomena under study. Third-grade high school girls were selected based on cluster sampling and were randomly divided into two experimental and control groups. The experimental received pronunciation instruction via PRAAT but the control group attended traditional classes with learning pronunciations through repetitions and practice. The participants took a pretest of pronunciation at the beginning of the intervention period; and after the intervention sessions, the same test was given to both groups in the posttest. Faunally, an attitude questionnaire was given to the experimental group eliciting their views on the use of PRAAT software in learning pronunciation. The data was gathered and analyzed through t-test analysis. The results showed that the experimental group who were taught by PRAAT outperformed significantly the control group who were taught by the traditional approach to learning English language pronunciation. Moreover, the findings indicated that the EFL students were interested in learning pronunciation via PRAAT. Implications suggest that EFL students were provided with the opportunity to practice pronunciation using pronunciation tasks via technology.

Conclusion: In techniques where high quality DNA is required like genetic engineering, micro arrays, extraction of DNA through kit method should be preferred, while in cases where quantity of DNA maters over its quality CTAB method is better to be used and economic.
Indonesian Blasphemy Law as Legal Forum for Renegotiating Indonesian Secularity
Authors: Muktiono
Published: September 2022

If secularism is described merely as the decline of religious roles in public spheres or religious privatization, then there would be difficulties to put the secular term on Indonesian history. The principle of divinity “Ketuhanan Yang Maha Esa” as adopted on the “Pancasila” as state ideology has become basis for religionization and rejecting any utterance of secularism at law, State institution, or other public domain. On the other hand, Indonesia as a democratic State as well as the most populous Muslim country in the world has never put the notion of Islamic state or theocracy as its State model. Its modernity is developed under the Western idea of law supremacy or the rule of law to which a democratic political system is laid down. This situation seems to be paradoxical in the view of both religionist or modernist due to its inconsistency to their strict concept especially on Islamic state and secularism. Or, is Indonesia another example of how religion and modernity has its multiplicity based its own historical reflexivity without making clash between religion and secularism? This article is intended to seek kind of distinction on Indonesian secularity based on how its blasphemy law developed and functioned under the framework of open-ended negotiation. The first epoch assumed as the place of negotiation on Indonesian secularity was taken place on initial stage of State’s formation around transition era of independence in 1945. Then, there have been several renegotiations afterward through multiple and overlapping instruments of development such as politics, economy, law, and culture. The blasphemy law as one of such instruments will be used to read how the relevant actors of Indonesian history has constructed their own concept of state and religion included its interrelationship characters as the basis for social and structural differentiation or distinction. The expected outcome of the reading and its analysis is to reveal any evidence of Indonesian particularity on secularization which may be related to the concept of multiple secularities.

Published: September 2022

Mindfulness-based interventions (MBIs) have shown efficacy with diverse populations. The training periods for sport MBIs range 4-10 weeks, but positive outcomes have been found during the first 2-4 weeks This is promising as athletes have busy schedules. Additionally, smartphone MBIs are gaining in popularity, but research with them is just beginning. Therefore, the purpose of this pilot study was to investigate a brief MBI with competitive high school baseball players. Participants included four athletes (mean 15.6 years) from one club team and their head coach. The athletes completed mindfulness training via Headspace (headspace.com). Each athlete was interviewed post-intervention. The head coach was also interviewed to gain insight into any observed changes in his athletes. Consensual Qualitative Research analysis resulted in four categories: Mindfulness, Readiness for Competition, Self-confidence, and Perceptions of the Intervention. All athletes discussed the MBI as facilitative for mental preparation for competition. Further, one athlete initially reporting low self-confidence, felt that his confidence improved after participation in the pilot study. Finally, all participants identified the app as a convenient way to practice mindfulness given their busy schedules. Positive outcomes in the current study are supported in the literature and provide insight into the efficacy and acceptability of a smartphone MBI. Future directions for research and implications for applied settings are discussed.

Published: September 2022

This chapter reports a study conducted by students as an independent research project under the mentorship of a Research Scientist at the National Institute of Education, Singapore. In the Life2Well Project (Learning at the intersection of AI, physiology, EEG, our environment and well-being) identical units of a wearable device containing environmental sensors (such as ambient temperature, air pressure, infrared radiation and relative humidity) were designed and worn respectively by five adolescents from July to December 2021. Over the same period, data from these sensors was complemented by that obtained from smartwatches (namely blood oxygen saturation, heart rate and its variability, body temperature, respiration rate and sleep score). More than 40,000 data points were eventually collected, and were processed through a random forest regression model, which is a supervised learning algorithm that uses ensemble learning methods for regression. Results showed that the most influential microclimatic factors on biometric indicators were noise, and the concentrations of carbon dioxide and dust. Subsequently, more complex inferences were made from Shapley value interpretation of the regression models. Such findings suggest implications for the design of living conditions with respect to the interaction of microclimate and human health and comfort.

Methods: The current descriptive-analytical study was conducted on the histopathologic slides of 46 BCC and 30 cSCC samples prepared by using Sirius red and Toluidine blue staining techniques for eosinophil and mast cell counts, respectively. The data were analyzed, using Pearson’s correlation, t test, and ANOVA test. Results: The BCC and cSCC samples had mean eosinophil counts of 35.43 ± 35 and 331.27 ± 321.68 eosinophil/10 HPF, respectively, and this difference was statistically significant (P = 0.001). The levels of the mast cell infiltration were obtained as 55.33 ± 39.90 and 63.67 ± 40.86 in BCC and cSCC, respectively. However, this variable was not significantly different between the two groups of BCC and cSCC samples (P = 0.380). In addition, the mean eosinophil and mast cell counts were higher in cSCC grade III than in other grades; however, this difference was statistically significant only for the mast cells. Furthermore, the mean eosinophil/mast cell count in cSCC and BCC showed no significant relationship with age and gender. Conclusions: Considering the greater presence of eosinophils in cSCC than in BCC, eosinophils may be concluded to be among the factors responsible for more biologically and clinically invasive behaviors of cSCC, compared to those of BCC.

To avoid the harmful effects of synthetic herbicides on human health and environment, and the development of herbicide resistance in weeds, considerable effort has been devoted to finding alternative products derived from natural sources. Allelopathy is the biological phenomenon of chemical interactions, and must be taken into account in addressing weed problems in future sustainable agriculture. Essential oils are volatile and concentrated liquids extracted from different parts of plants. Bioactive compounds found in EOs, especially terpenes and terpenoids possess a wide range of biological activities including anticancer, antimicrobial, anti-inflammatory, antioxidant, antiallergic and allelopathic. Essential oils from many aromatic, cultivated plants and weeds are sources of compounds with bioherbicidal potential. This review is focused on chemical composition of essential oils, traditional and innovative methods of extraction and gas chromatography-mass spectrometry, which we can use for analyze the composition of the essential oil. Also, this review discusses possible ways of testing the bioherbicidal properties of essential oils. Knowledge of essential oil extraction and identification methods is necessary for further studies, in order to evaluate the phytotoxic activity of these compounds under controlled conditions, determine their activity in the field, evaluate their safety, and assess their modes of action.

To mark the great jubilee of the Natural History Museum in Belgrade - 125 years since its founding - members of the Editorial Board has decided to publish, in the upcoming editions of the Bulletin, biographies of those who contributed the most to the establishment of the Museum and its initial collections. In this way, we would like to thank our predecessors for their immense work and great driving energy, not just in laying the foundations but also in ensuring the continuity of the work of the Museum. At the same time, we also want to acquaint the wider scientific and professional public, as well as younger generations of naturalists, with the important persons from the Museum's rich historiography.
2D electrical imaging investigations at the Neolithic settlement "Pločnik"
Authors: Arnaut Filip , Sretenović Branislav
Published: September 2022

At the Neolithic settlement "Pločnik" near Prokuplje in Serbia, the electrical imaging method (ERT) was deployed. At the sounding site S-3, 1D electrical survey revealed a low resistivity layer with a thickness of 0.8 meters and a resistivity of about 30 Ωm. A sharp and steep boundary divides the high resistivity medium and the low resistivity medium, according to the 2D electrical survey. The resolution of the ERT method was tested using 3D forward and inverse modeling to see whether it could distinguish the high resistivity pit from the surrounding high resistivity gravel.

Published: September 2022

This paper presents an approach for developing the programming and offline simulation systems for low-cost industrial robots in the MatLab/Simulink environment. The approach is presented in the example of a virtual model of a 4-axis robot with hybrid kinematics intended for manipulation tasks. The industrial robot with hybrid kinematics consists of the well-known 5R planar parallel mechanism to which two serial axes have been added. The programming system developed in a MatLab environment involves generating G-code programs based on given pick and place points. The virtual model included in the simulation system is configured in the Simulink environment based on the CAD model of the robot and its kinematic structure. The kinematic model and the inverse kinematic problem have to be included in the virtual model to realize the motion of the virtual robot. The system of programming and simulation has been verified through several examples that include object manipulation to perform various tasks.
Evaluation and multi-criteria optimization of surface roughness, deviation from dimensional accuracy and roundness error in drilling CFRP/Ti6Al4 stacks
Authors: Motorcu Ali , Ekici Ergün
Published: September 2022

In this study, machinability tests were carried out to investigate the effects of control factors (cutting tool geometry, cutting speed, and feed rate) on the surface roughness (Ra), deviation from dimensional accuracy (Da_dev), roundness error (Re) in drilling CFRP/Ti6Al4V mixed metallic stack and to determine the optimum levels of drilling parameters. The effects of each control factor and their interactions on three quality characteristics were analyzed, and their levels were single-objectively optimized for each component material by the Taguchi method. The material has components (CFRP and Ti6Al4V) with essentially different properties (mechanical, physical, machinability). Single-objective optimization has limited usability as the drilling must be performed in one through both layers. Therefore, in an additional step, the optimum levels of the control factors were determined by optimizing multi-objective with the Additive Ratio Assessment (ARAS) method. Higher Ra, Da_dev, and Re values were obtained on the CFRP component compared to the Ti6Al4V component. The CFRP/Ti6Al4V stack should be drilled with a nano fire coated carbide drill (T3) at medium cutting speed and high feed rate to achieve minimum Ra, Da_dev, and Re values in one go.

The problems solved by the chemography method based on fixing oxidative reactions of ultra-low concentrations on the surface of solids are discussed. This method makes it possible to fix physical defects (microcracks, destruction, violations of structural homogeneity) and the energy (residual stresses) state of the surface layer of materials under operating conditions under the action of thermobaric loading. The change in these parameters is associated with the degradation of the cutting surfaces and, as a result, with a change in the rate of the reactions taking place. Applied chemography phenomena as a method of visualization of a destructive layer, a network of surface micro cracks in studying the processes of destruction materials, including nonmetallic ones, is shown. The main advantages of this method are the possibility of assessing the level of residual stresses and periodic visualization of surface defects due to the state of the studied materials, including nonmetallic ones. A relationship has been established between the presence of defects, the level of residual stresses, and the intensity of emerging photo molecular fluxes. In the applied aspect, the method makes it possible to evaluate the performance of cutting plates, and to study the formation and development of a network of microcracks by the intensity of the chemographic effect.

Published: September 2022

This paper presents the proportional-derivative fuzzy controller for trajectory tracking of the gripping mechanism with two degrees of freedom. Aiming to achieve movement of the gripping mechanism without sudden starting and stopping, a polynomial velocity profile is utilized. The African vultures optimization, as one of the latest metaheuristic algorithms, is used to obtain the optimal input/output scaling gains of the proposed fuzzy controller according to the selected fitness function. The results obtained by this algorithm are compared with the other three new and popular metaheuristic algorithms: the whale optimization, the ant lion optimization and the sine cosine algorithm. Moreover, a simulation study was done for the defined initial position and for the scenario where there is a certain deviation because the gripping mechanism is not at its original initial position. Finally, the robustness of the controller is tested for the case when the masses of the segments increase three times. The results revealed that the suggested controller was capable of dealing with nonlinearities of the gripping mechanism, initial position and parameter changes. The movement of the gripping mechanism is smooth and follows the defined trajectory.
