Authors: Ventura Ríos Joel , Honorato Salazar José Amador , Apolinar Hidalgo Flora , Barrera Martinez Iliana , Aburto Anell Jorge , Vaquera Huerta Humberto
Published: January 2022

The objective of this study was to evaluate the biomass production, chemical composition, proximate analysis, calorific value and theoretical yield of bioethanol of Taiwan grass under 6 cutting frequencies. The highest production of biomass (33 t DM/ha), cellulose content (41.3%), calorific value (17.5 MJ/kg DM) and potential bioethanol yield (7,936 L/ha) were recorded at a cutting frequency of 180 days. The highest moisture content of the dehydrated samples and ash and crude protein concentrations were observed at a harvest frequency of 30 days with 9.2, 12.1 and 10.5%, respectively. The highest concentrations of extractives were obtained at harvest frequencies of 60 and 120 days (13.9 and 13.7%, respectively), while lignin concentrations were greatest at harvest frequencies of 150 and 180 days (21.1 and 20.9%, respectively). The highest concentration of fixed carbon was observed at a harvest frequency of 90 days (18.5%), while the lowest concentration of volatile matter occurred at a harvest frequency of 30 days. The data indicate that Taiwan grass has significant potential for use to produce bioethanol but assessment of the carbon footprint, life cycle analysis, energy yield (energy produced:energy consumed) of the entire production process is needed to ensure there are positive effects on climate change and greenhouse gas emissions before this process is adopted.
Evaluation of land use change on an andosol through physicochemical and biological indicators
Authors: Ordoñez Maria-Cristina , Galicia Leopoldo , Casanova Olaya Juan Fernando
Published: January 2022

The conversion of forests to agricultural land can dramatically alter soil properties, but soil resistance, which is theability of soil properties or processes to remain unchanged in the face of a specific disturbance or stress, remainsunclear. We evaluated the impact of land use change and agricultural management on changes on an andosol in theCauca department, Colombia, through the analysis of physicochemical variables and biological indicators (dimensionlessresistance index, where +1 is the highest resistance and -1 is the lowest resistance) that allowed the assessment of soilresistance. The land uses analyzed included (1st) forest, which was approximately 100 years of age, plus areas of the same forest (70% of the area), which had been replaced by (2nd) natural pastures and (3rd) forage crops in the year 1985, i.e. 30 years before the observations. All physicochemical variables except soil clay content were significantly affected by the change from forest to natural pasture. Similarly, the change from forest to forage cropping affected all physicochemical variables as well as resulting in a decrease in soil microbial biomass but an increase in microbial activity. We found that the metabolic quotient (-0.32) had the lowest resistance, followed by the microbial coefficient (0.19), microbial biomass (0.32) and microbial activity (0.39), suggesting that soil stress caused by disturbance has a marked impact on the number and activity of the soil microflora. By contrast the change from forest to natural pastures was not associated with any effect on microbial biomass and its activity, suggesting that the continuous input of organic matter to the soil through the supply of organic residues from diversified root systems and nutrients from livestock urine and manure favored the preservation and resistance of microbial processes in the soil. These findings suggest that deforestation to establish natural pasture has less impact on soil stability and health than cultivating the soil following clearing.
A critical analysis of Zimbabwe's codified business judgment rule and its place in the corporate governance landscape
Authors: Hamadziripi Friedrich , Osode Patrick C.
Published: January 2022

The business judgment rule (BJR or the Rule) is an American legal export which has become a key corporate governance tool in most leading common law jurisdictions, such as, Australia, Canada and South Africa. However, the Rule has not been formally embraced in the United Kingdom. In Zimbabwe, the Rule has traditionally been treated as a common law feature. However, section 54 of Zimbabwe's new Companies and Other Business Entities Act represents one of the significant advances in strengthening the jurisdiction's corporate governance principles by codifying the Rule. The BJR originated together with the directors' duty of care and skill. There are two main formulations of the BJR. The first one is by the Delaware Chancery Court and the second one derives from the American Law Institute's Principles of Corporate Governance. The Rule mostly applies in determining the procedural aspects of the directors' decision or the decision-making process and only in exceptional cases is it invoked to review the merits of their decision. This article seeks to critically analyse the major elements of Zimbabwe's codified BJR and to ascertain its place in the corporate governance framework. As will become clear, it will also be argued that the statutory BJR is intended for the enhancement of directorial accountability.

Published: January 2022

The influence of different drying temperatures and slice thicknesses on the
drying kinetics of turmeric slices was studied to show how moisture is
removed. The best model for predicting the drying kinetics was also
determined. Turmeric slices (3 mm, 5 mm, and 7 mm) were dried at 40, 50,
and 60 °C in a laboratory oven dryer. Four thin layer drying models (Newton,
Henderson and Pabis, Logarithmic, and Page) were fitted to the experimental
data and the selection was done based on the model with the highest correlation coefficient (R2), and lowest reduced chi-square (χ2), the sum of square error
(SSE), and root mean square error (RMSE). Drying time varied between 420
min and 1140 min as the air temperature increased from 40 °C to 60 °C. The
effective moisture diffusivity coefficient increased with increasing drying
temperature and was found to be between 1.35×10-10 m2/s, and 5.00×10-10 m2/s,
3.00×10-10 m2/s and 10.91×10-10 m2/s, and 4.56×10-10 m2/s and 13.00×10-10 m2/s at 40 °C, 50 °C, and 60 °C, respectively. The values obtained for the activation
energy for moisture diffusion were found to be 56.809, 56.060, and 45.561
kJ/mol for 3, 5, and 7 mm, respectively. The page model was found to best
describe the oven drying of turmeric slices.

Authors: Adelekan Aminat Olabisi , Alamu, Emmanuel Adediran , Daramola Bolanle Esther
Published: January 2022

Ogi is a fermented maize product which is commonly used as weaning food
for children and as breakfast for adults. This study was conducted to evaluate
the effect of enrichment with turmeric and ginger on some quality parameters
of ogi flour. Turmeric and ginger slurries were prepared and added to the ogi
slurry at different percentages as follows: 0CC (100% ogi), GN1 (95% ogi +
5% ginger), GN2 (90% ogi + 10% ginger), GN3 (85% ogi + 15% ginger), TM1
(95% ogi + 5% turmeric), TM2 (90% ogi + 10% turmeric) and TM3 (85% ogi
+ 15% turmeric). The samples were fermented for 48 h, dried at 55 °C for 24
h to flour and then packaged. Microbial, pH and total titratable acidity (TTA)
evaluations were carried out on the samples during fermentation. Nutritional
and anti-nutritional contents were also determined. Results showed that the pH
of the spiced ogi slurry decreased as total titratable acidity increased during
fermentation. The proximate composition showed significant differences
(p≤0.05) and increased with the addition of ginger and turmeric, respectively.
Considering the ash, crude fat and crude protein contents, the sample TM1 had
the highest value of 1.21, 5.92, and 11.89%, while the sample 0CC had the
lowest value of 0.64, 3.64, and 5.58%, respectively. The vitamin
determinations showed that the sample TM3 had the highest values of vitamin
B2, B6 and D. The highest value was recorded in Vitamin C for the sample GN3
(85% ogi + 15% ginger), while the lowest value was recorded in the sample
TM1 (95% ogi + 5% turmeric). Tannin, phytate and trypsin inhibitor showed
the highest values in the sample TM3. The sensory evaluation showed that the
sample GN1 was the most preferred sample. The study established that the
enrichment of ogi with turmeric and ginger slurries will improve the nutritional
status of major consumers of ogi.

The purpose of this study is to assess the effectiveness of paracord anklet and bracelet made up of guyabano (Annona Muricata) seeds and wormwood plant (Artemisia Absinthium) extract as mosquito repellent and to determine if the paracord anklet and bracelet can be as effective as the commercial patch used in this study. In the study, 2 groups were examined: The experimental group and the control group. The experimental group with variation 1 (50 guyabano seed, 80% of water, and wormwood extract), variation 2 (75 Guyabano seed, 50% of water, and wormwood extract), and variation 3 (100 Guyabano seed, 30% of water, and wormwood extract). The control group was tested with the commercialized patch. Results showed that the overall gathered data showed very promising effectiveness, with a level of effectiveness of 6.5 means. Furthermore, the ANOVA showed no differences at all between the Control and Experimental Group (fcalc 2.20fcrit3.49, P=0.13). This may therefore mean that the paracord anklet and bracelet made up of guyabano and wormwood plant is as effective as the commercial patch used in this study. This study shows that the paracord anklet and bracelet can be considered as an alternative and environmentally friendly mosquito repellent.

Authors: Chaihang Sirawit , Puengsungwan Supachai
Published: January 2022

This paper presented a smart moving-spiral-clothesline for urban life. The design of the clothes dryer is flat and used in the manner of spiral movement. 3D models have been designed to show the basic component of the proposed smart clothesline. To evaluate the proposed system, the simulation results have been set up to show the operation of the proposed system. The proposed system of the clothes drying rack (spiral moving type) can support the drying weight of 2.5 kg per one drying time, which can save 68.2% of the space compared to old clothes drying (fix type). This, consequently, can assist in terms of movable space. The proposed system can also analyze the situation when dust affecting the drying may damage clothes from the simulation of the operation of the device and the sensor. It is found that the proposed equipment can be used in the actual design. In addition, t is necessary to adjust the light value to suit the installation area to prevent equipment failure.

Authors: Khurram Shahzada , Khalid Perveiz
Published: January 2022

Self-generated earthquake catalogue of Mw≥6.0 upto 300 km depth was prepared for the inversion of six components of moment tensor. Seismotectonic map was drawn with seismicity distribution. The stress map of Pakistan was generated through CASMO which described by the Anderson model (1951). The maximum horizontal stress (SHmax) acting in the compressional zone generates reverse faulting (RF) causes to form the three distressing mountainous range called Karakorum, Hindukush and Himalayan i-e SHmaxSHmin. In eastern side of Pakistan, minimum horizontal stress (SHmin) acting in the extensional zone produced normal fault (NF) i-e SHmax SHmin. Focal mechanism was also drawn using source parameters of each event obtained by matlab codes. Stress tensor components were obtained using mathematical equations and out comes were written in the form of 3x3 matrix. All matrices have non trivial solutions and their solution sets were also evaluated in the form of eigen values and eigen vectors. Crustal thickness was displayed by thickness map. The maximum thickness of curst in northern Pakistan i-e 60-70 km whereas in southwestern region this varied from 20– 40 km all around.  This variation due to plate motion intensity and velocity of Indian and Eurasian plate collision.

Authors: Kantroo Sadia , Srivastava Amit , Sharma Alok
Published: January 2022

Rubber tyre waste is a huge burden on environmental system. In the present study, performance of gravity retaining wall system is assessed, both in deterministic and probabilistic framework, by utilizing rubber waste mix in the backfill. In the probabilistic approach, performance of a geotechnical system is measured in terms of an index popularly called “reliability index b”, a measure of probability of success of system. Concept of response surface methodology (RSM) has been applied to establish an approximate functional relationship between input geotechnical parameters, and output response, i.e. factor of safety through numerical analysis and then reliability index b is evaluated using FORM approach. Present study demonstrates the two aspects, i.e., by considering the case of a gravity retaining wall, i.e., reliability of computed value of factor of safety and role of mixing tyre chips in improving the performance of gravity wall system

Published: January 2022

Scheduling can be seen in many areas such as chemical processing, logistic, supply chain, and class. In this study, two different cases of scheduling problems are addressed which are batch reactor process scheduling and University Class Scheduling (UCS) problems. The aim for the batch reactor process scheduling is to minimize the total discrepancies between the size of the assigned reactors and their corresponding assigned capacities or reactor sizes. The approach taken into consideration includes some constraints such as desired products, the production capacities, and the reactor capacities. Meanwhile, for the UCS problem, the concern is on the number of needed courses assign to certain classrooms while at the same time noting the constraints such as the size of the classroom and the number students. The UCS problem also seeks to optimize the distribution of courses remarkably to classrooms refers to the ratio of classroom capacity to course enrolment. These issues will be resolved using Integer Linear Programming (ILP) in the form of Excel-based software. The ILP model tool for both scheduling problems, therefore, is developed and resolved using the Excel solver utilizing Visual Basic Applications (VBA) and Macro.

The purpose of this study was to determine the preferred mode of interaction of generation Z. There are four novelties: (1) To understand the percentage of students who prefer social media as a medium of social interaction, (2) To know the percentage of students who prefer face-to-face interaction, (3) To comprehend what medium do they prefer to use when they are discussing their courtship involvement, academic matters, personal issues, interpersonal relational conflicts, sex-related matters, and (4) To know the reasons for students' preference in terms of mode of Interaction. The study used a mixed-method approach, employed explanatory design, and used simple random sampling in choosing the 76 respondents/participants from the Sultan Kudarat State University (SKSU) students. A survey and an interview were conducted to compare face-to-face interaction and social media interaction as the primary mode of interaction. The results showed that 60 students prefer face-to-face interaction over 76 students, with a frequency of 78.94% out of 100%. It is concluded that most of the students prefer face-to-face social interaction rather than social media. This study has an impact on Generation Z, as it serves as a realization of their social activeness in interaction as well as on the community. Also, it will help society understand how Generation Z compares to other generations by being the generation most affected by technology and its rapidly evolving form of communication, as well as the loss of their ability to communicate.

English club was a club of students with common ambitions or interests in English. This study aims to find out Students’ Perceptions of Speaking Practice in the Step-Up English Club (SU) club. This study used the qualitative method, observation, and interview as research instruments. The subject of this study is the members of the SU club as participants. As the result of interviews, most of the students had positive perceptions about joining in SU club, yet some still haven't adapted to the online meetings. The students believe that SU clubs could improve their fluency. The student also had a perception through an English meeting club as a proper environment to enhance skills especially in speaking. There are similarities between this research and the previous research. English meeting clubs have a positive influence on learning English. However, there are some different results found, especially from the social distancing time during Covid 19 pandemic. Positively, with both online meetings and offline meetings, the SU Club gives students a place to properly practice speaking English without fear to make mistakes and is an appropriate medium to improve students' speaking skills. However, English clubs, in general, should design more diverse and fun activities, to gradually change students' reluctance to take online sessions.

Energy consumption that still use fossil energy or non-renewable energy has a negative impact on the environment. Alternative energy innovations or renewable energy have also begun to be developed to replace fossil energy or non-renewable energy. This study aims to determine whether other types of plants that wasn’t used by Helder could also generate electricity and reduce the impact of non-renewable energy. This research was conducted by placing electrodes on the soil close to the roots of the plants. In this experiment, we used 3 types of plants that are common at home, namely Chrysanthemum, Orchid, and Red Begonia. The results show that there is indeed a very small flow of electricity, this could possibly due to various factors. If this experiment continues to develop, the possibility of green-electrical energy could be more than just a dream. Based on experiments using a prototype that we have done, the three plants have the potential to produce electric currents in the range of 0.02mA-0.65mA.

Fossil fuels are the main source in producing electrical energy continuously on a large scale in various countries. This will have an impact on the exhaustion of fossil fuels. Therefore, energy substitute for fossil fuels is needed. PLTMH is a renewable energy source that uses water to solve the problem of electrical energy. The purpose of this study is to determine the water discharge, the speed of water flow that comes from tap water as a source of electricity generation. Based on research in the journal, the novelty is the manufacture of power plants using simple tools to produce good and accurate research data. The research method used is literature study. Literature studies are taken from various sources that describe power generation tools using energy. From the research results in the journal, it can be seen that the higher the water discharge, the higher the mechanical efficiency of the propeller turbine. In addition, the higher the water discharge also affects the generator output power. The conclusion of this study is that the water flow that is flowed from tap water to the hose greatly affects the voltage generated, where the electric voltage will be greater if the efficiency of the turbine mechanism which acts as a mechanical energy converter and the generator output power as an electrical energy converter is high enough. The impact of the research is expected to continue to be developed and be useful as renewable energy for electrical energy problems.
