Authors: Kusumaningrum Shirly Rizki , Widiati Utami , Anwar Khoirul , Farisia Hernik
Published: September 2022

Abstract: Now that the spread of Covid 19 is still high and the teaching and learning process should be continued to be conducted at homes, but it seems that some teachers –in this case EYL teachers– are not ready to integrate various digital platforms. It is necessary for us to respond to the need of investigating technology readiness of English for young learners teachers in teaching during this Covid 19 pandemic. It is strongly important to reveal the teachers’ technology readiness as it plays vital role, especially during this pandemic —when the only thing that the teachers and the students can do is interacting online. Without having adequate literacy in technological thing, it is impossible to create teaching and learning process which can facilitate both the teachers and the students. Based on the result of initial survey, it could be stated that some teachers might not be ready in integrating the technology in their virtual classrooms; ending up in either providing lots of assignments or creating monotonous activities, which of course break the nature of teaching English for young learners. Hence, it is expected that by conducting this study, the researchers could assist some of the teachers to be more aware with their technology readiness, so that they could serve the students better, and the students could also learn the material more interesting and meaningful.

Arguing for the Philosophy of Political Science
Authors: Herold Robert
Published: September 2022

While there are many working scientists who engage in things like theory building and empirical testing, there has also been a group of scientists who sought to better understand the philosophy behind science. This philosophical study of science as a project is referred to as the philosophy of science and there are different sub-fields for each of the natural and social sciences, except for political science. This lack of an explicit sub-field dedicated to reflecting on our philosophy of science, i.e., our beliefs, values, methods, etc., has caused this knowledge to become tacit within our community. Because the knowledge of our philosophy of science is now tacit, we as a community are hindered in our capacity to engage in critical self-reflection which is an important part of any scientific endeavor. However, what has been is not what need be moving forward, we can still turn this tacit knowledge into formal knowledge which will then allow us to grow as a community. This thesis will demonstrate a few of the ways in which our knowledge of the philosophy of our science has become tacit, and why this is indeed a bad thing. The specific topic areas addressed are the misunderstandings of the natural sciences in our community, the process of categorization, and our goals as a scientific tradition. This is in service of the true goal of this thesis project, which is to give a proper augment for the creation of the philosophy of political science as an explicit sub-field.
Rapid, Reliable Tissue Fractionation Algorithm for Commercial Scale Biorefineries
Authors: Kancharla Rahul Reddy
Published: September 2022

Increasing demand, limited supply, and the impact on the environment raise significant concerns about the consumption of fossil fuels. Because of this, global economies are facing two significant energy challenges: i) securing the supply of reliable and affordable energy and ii) achieving the transformation to a low-carbon, high-efficiency, and sustainable energy system. Recently, there has been growing interest in developing portable transportation fuels from biomass in order to reduce the petroleum consumption in the transportation sector - a major contributor to greenhouse gas emission. A cost-effective conversion process to produce biofuels from lignocellulosic biomass material relies not just on the material quality, but also on the biorefinery’s ability to measure the quality of the source biomass. The quality of the feedstock is crucial for a commercially viable conversion platform. This research mainly focuses on developing sensing techniques using 3D X-ray imaging to study quality factors like material composition, ash content and moisture content which affect the conversion efficiency, equipment wear, and product yield in the bioethanol production in a real-time or near real-time basis.

Authors: Jadhao Suraj , Bairwa B. L. , Sharma Vinod , Chopra Sanjeev
Published: September 2022

Background: Traumatic brain injury (TBI) is the leading cause of death in trauma patients in various parts of the world including India. Coagulation cascade is affected in TBI.  The severity of coagulopathy correlates with degree of primary injuries thus affecting the prognosis of geriatric patients. Since the prognosis of isolated TBI can be a challenge to predict at times. AIM: we wanted to study the potential of international normalized ratio (INR) test, prothrombin test (PT), platelet count as a prognostic tool in isolated TBI. Methods: INR, PT, platelet count reflects the coagulation status. In most trauma cases, it is a routine test as well. We collected the INR, PT, platelet count value at admission of 200 isolated geriatric TBI cases over a period of three months. Then, patients were followed-up and their outcome at three months from admission is scored using Glasgow outcome scale (GOS). The relationship of INR, PT, platelet count with GOS was studied.Results: From our limited study, we found that INR of 1.52, PT 17 sec or more and platelet count less than 1.10 lac predicts poor prognosis in cases of isolated geriatric TBI.Conclusions: It is important to early diagnose and early manage the coagulation abnormalities in isolated geriatric head injury patients.

Published: September 2022

In this paper, the temperature distribution in a slab was investigated. A model based on the Boltzmann transport equation without heat source was simplified using the Bhatnagar-Gross-Krook (BGK) approximation was applied. This is an example of the Lattice Boltzmann Method. The model was developed based on using a D2Q4 lattice arrangement for the medium of study. To obtain results, the model was tested on different cases: Two box-shaped slabs with different boundary conditions, and a T-shaped and an L-shaped slabs to determine the temperature distributions different times t > 0. The results obtained based on the developed model were validated with the enterprise software COMSOL Multiphysics which is based on the Finite Element Method. For the two cases of box-shaped and the T-shaped slabs, their results were in nearly perfect agreement with the finite element method. However, for the L-shaped slab, there was good agreement at most points apart from the regions where there was change of shape. In conclusion there is high agreement between the results of LBM and using COMSOL, which proves that LBM can be used to determine temperature distribution in a slab accurately.

Authors: Mahmood Nabeel S. , Aude Samar A. , Abdullah Hasan H. , Sulaiman Sadeq O. , Al Ansari Nadhir
Published: September 2022

The design of dams requires comprehensive studies to ensure the safety and feasibility of these important engineering projects, as any possible failure case may lead to considerable losses in human life and properties. Specifically, analyses should be performed to evaluate seepage, slope stability, and soil liquefaction of large earth dams. In this study, numerical modeling, based on finite element methods, was used to analyze seepage, slope stability, and liquefaction of Makhoul Dam which is a large zoned dam, currently under construction on Tigris River in the north of Iraq. Earthquake shakings impose additional hysteric and short-term loads that may lead to dam failure due to high pore water pressure, piping, and soil liquefaction. Therefore, the dynamic stability of the dam and soil liquefaction were also evaluated, as a result of applying an earthquake shaking to the dam. For the static condition, the dam was safe against internal erosion and slope failure, as the calculated value of the safety factor was greater than the allowable value. However, the results obtained from the dynamic analysis indicated that a possible earthquake, with an acceleration of 0.38g and 10 seconds period, led to upstream slope failure, a relative displacement as high as 2 meters at the dam crest, and soil liquefaction at the upstream slope. As discussed herein, dam redesign or geotextile reinforcement may be considered to reduce the effects of earthquakes on the dam.

Introduction: Benzene, Toluene, Ethylbenzene, and Xylene (BTEX) as the ozone precursors have been classified as the hazardous air pollutants because of their negative effects on humans. This article presents the results of the first assessment of source identification, spatial distribution and BTEX's Ozone- Forming Potential (OFP) in Zarand.
Materials and methods: The current study was conducted at 30 geographically separated locations, in Zarand, Kerman, southeastern Iran, during the summer and winter of 2020. BTEX samples were collected using passive samplers and then analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). Spatial variations were surveyed using the Kriging method in GIS.
Results: Total BTEX levels (79.26±26.87 µg/m3) during the summer were greater than their levels in the winter (37.38±29.18 µg/m3). The ranking of BTEX level in all samples followed as: toluene>m,p-xylene>o- xylene>ethylbenzene>benzene. The overall OFP of 374.79±135.08 µg/m3 in the summer and 172.61±148.81 µg/m3 in the winter were more than 100 µg/m3 as recommended guideline defined by World Health Organization (WHO), with toluene having the highest potential.
Conclusion: According to the results of the present study, BTEX relative abundances in all samples were toluene>m,p-xylene>o- xylene>ethylbenzene>benzene. Despite of concerns among inhabitants and workers, benzene concentration was lower than other studied species. Control measures such as management of fuel use in motor vehicles and industries and development of green space must be adopted to attenuate the level of toluene in the atmosphere in the studied area.

Published: September 2022

Introduction: Deteriorated air quality in nation like India contributes to the health burden. The AirQ+ is used to estimate short-term and long-term health impact attributable to surface Ozone (O3) in Surat city. Average hourly ozone concentration data and other criteria pollutants retrieved from January 2018 to December 2019 from two monitoring stations (Limbayat and Varachha).
Materials and methods: In this study, the Respiratory Mortality (RM), Cardiovascular Mortality (CM), Total Mortality (TM), Hospital Admissions with Cardiovascular Disease (HACVD), and Hospital Admissions with Respiratory Disease (HARD), as well as Respiratory Mortality-Long-Term (LT-RM) were quantified. Baseline Incidence (BI) data were obtained from literature and Relative Risk (RR) values were referred from World Health Organization (WHO). An annual Sum of Maximum 8 h Ozone means over 35 ppb (SOMO35), 70 µg/m3, used as a predictor of potential long-term health effects.
Results: More ozone concentration were observed in winter and pre-monsoon than concentration formed in southwest monsoon and post-monsoon seasons.The average of O3 concentration for Limbayat are 71.61 (±0.39) µg/m3 and 29.76 (±1.86) µg/m3 and for Varachha are 61.17 9 (±6.15) µg/m3, 11.32 (±1.35) µg/m3 during 2018 and 2019, respectively and the obtained cumulative number of cases of death are estimated 136, 45, 172 and 18 persons respectively. Total hospital admission due to cardiovascular and respiratory diseases are found 435, 134, 552 and 58 at Limbayat and Varachha during 2018 and 2019. LT- RM is attributed to ozone concentration having the most significant value, 6.8% and 4.62% at Limbayat and Varachha in 2018.
Conclusion: More hospital admissions are found than mortality rates using AirQ+ tool. It can be used to estimate public health in context of mortality and morbidity rates which helps to develop air quality management programs and policy makers to reduce the impact of air pollution on health.

Introduction: Air pollution in cosmopolitan cities is increasingly becoming unprecedented with attendant effects on human and biophysical attributes.
Materials and methods: The study was carried out at Federal University of Technology (FUTO) and environs in the southeastern Nigeria. Some ambient air quality parameters (CO, CO2, NO2, CH4 and noise) were sampled and. measured at seven unique locations (OR, ER, FR, EJ, IM, FM and FJ) with multi sampler devices, using air differential technique during the morning, midday and evening periods.
Results: The average pollutant results show increased concentrations at the different locations when compared to Occupational Safety and Health Administration (OSHA) than Federal Ministry of Environment (FMEnv) thresholds (FMEnv>CO2NO2CH4<OSHA). However, concentrations of CO and Noise in FR and FJ were relatively higher than concentrations observed in other locations (CO: FR [6.4 mg/m3] and FJ [4.2 mg/m3]; Noise: FR [96.8 dB] and FJ [95.7 mg/m3]) respectively.
Conclusion: The significant increase could be attributed to continuous vehicular emissions and presence of make-shift activities in these locations. However, predictive model suggests that given the meteorological conditions and perceived anthropogenic activities over time, OSHA threshold could be evidently compromised.

Published: September 2022

Introduction: Air pollution increases the load of hospitalization cases, especially for those who have respiratory problems. For effective environmental management, this study aims to compare the performance of two classification algorithms in machine learning (logistic regression and naive bayes) and to evaluate the selection of the best algorithm for predicting the air quality class.
Materials and methods: Pollutants data (PM10, SO2, NO2) have been collected from the Haldwani, Kashipur and Rudrapur regions in Uttarakhand (India). In part I of the study, the Air Quality Index (AQI) is calculated and assigned a class accordingly. In part II, the performance of algorithms is compared, and the air quality class is predicted through the best algorithm. In part III, accuracy is calculated after comparing the predicted class with the actual class. Then, it is compared with the accuracy of our selected algorithm.
Results: The study finds a positive correlation between PM10 and SO2 pollutants. The result shows that the highest accuracy is achieved through logistic regression to predict the air quality class. Further, logistic regression has achieved the same accuracy i.e., 98.70% after comparing predicted values with the actual values.
Conclusion: Logistic regression is the best algorithm to predict the air quality class in the regions of Uttarakhand, where pollutants are being measured in the Government’s hospital. The research also indicates that asthma patients in the Kashipur and Rudrapur regions may experience more health effects due to moderately polluted air quality; however, the situation is improving during the monsoon season.
