Impact Assessment of Introducing High Speed Rail on CO2 Emissions in India
Authors: Verma Aditya
Published: January 2023

High Speed Rail (HSR) plays a significant role in economic urbanization and environmental impacts. India is also debating on the importance and impacts of HSR on climate. HSR is already operational in several countries today and a total of 12 HSR corridors are already planned in India, of which the construction of the Mumbai – Ahmedabad corridor is already underway. Even though there are several studies in literature in the context of various countries related to the impact of HSR on CO2 emissions, however such studies are very limited in Indian context. Keeping in mind that passenger travel is a major human activity contributing to CO2 emissions, the prime objective of this research is to study the impacts of HSR on CO2 emissions in Indian corridors. Hence a study of the Bengaluru – New Delhi corridor is taken. The hypothesis of the study is that introduction of HSR between Bengaluru – New Delhi will reduce CO2 emissions. Revealed Preference and Stated Preference survey was conducted using interview method for the purpose of data collection. Percentage shift of passengers from air travel to HSR was calculated. Thereafter the percentage reduction in CO2 emissions was calculated using emission factors from literature. It was found that there is a percentage reduction in CO2 emissions for all HSR options, and more so for the HSR option with night journey (with speed of 200 kmph) and moderate fare levels equivalent to the Rajdhani Express 2nd AC fares and that of a half day or night journey (with speed of 350 kmph) with fares equivalent to that of the Rajdhani 1st AC fare. The study suggests different possible options to introduce HSR in India that can reduce CO2 emissions from passenger travel and can help the Indian Government with some policy decision support.

Published: January 2023

A blind person always remain dependent on assistant to move from one place to another. If they move by themselves they can harm themselves because they are not able to identify the obstacle in their path. To make them independent a smart stick is proposed in this paper. This stick makes the blind person independent. A smart stick consists of different sensors to identify the obstacle. A speaker and buzzer to give the output in recorded voice after sensing the obstacle. In addition smart stick also consists of GPS and GSM module to navigate the path. The GPS module also plays a major role as it provides safe and precise navigation to the users. It also help relatives to track the blind person. The paper describes the different component and working of smart stick. The Smart Blind Stick automatically detects the obstacle in front of the person by use of sensors present in the systems, it also incorporates moisture detection at its bottom in order to detect the moisture of the soil or ground so that the person will be aware if it’s feasible to walk on that particular ground

Published: January 2023

Modern Power systems demand maintenance of essential security in the field of load shedding. We are still living in a society where a large number of houses go through long hours of power cuts in the locality. For many years, the increased effectiveness of the under-frequency load shedding (UFLS) schemes has proven to be a matter of research across the globe. Regrettably, the solution which was proposed mostly requires expensive technical resources and large amounts of real-time data monitoring. This paper presents a smart scheme for rapid and accurate load shedding using neural networks so that predicting the possible loss of load at the initial stage becomes feasible and neuro-fuzzy to determine how much load shed is to be done. The proposed techniques can provide tools for improving the reliability and continuity of the power supply. This was validated by the results obtained by various research papers reviewed in this paper. The authors aim to undermine an Underfrequency Load Shedding Scheme characterized by increased effectiveness where the case is of large disturbances and foreshortened power which was disconnected in the case of small disturbances compared to the old conventional load-shedding methods. The aim is to provide centralized and distributed load shedding strategies.
Evolution of Microgrid and Hierarchical Control of Microgrid
Authors: Pranavi Peddada HS , Panda Tatwamashi , Gupta Annika , P Sriramalakshmi , P Balamurugan
Published: January 2023

A microgrid is a local energy grid with control capability, which means it can disconnect from the traditional grid and operate autonomously. Our survey on this topic, focuses on the proposed technical control solutions for the various levels of the Microgrid organization hierarchy. An electric grid is an interconnected network where electricity is delivered from producers to consumers. Grids vary in sizes and consist of: power stations, electrical substations, electric power transmission and electric power distribution. The difference between a traditional grid and a microgrid can be clarified using an example: in a traditional system, if the power transmission source and load are out of balance, the power is instantly balanced by the system's rotational inertia, modifying the intensity, which is the simple concept of the P-f droop control method. The microgrid, on the other hand, lacks inertia because most of the microgrid's sources are renewable , making the microgrid control system architecture complex and difficult. This resulted in the development of a new control technique for microgrids called Hierarchical Control (HC), which has three levels: main control, secondary control, and tertiary. According to our research, as of 2021, about a billion individuals distributed across various places were unable to connect to the power grid due to a variety of issues, the most significant of which was difficult economic conditions. Our survey mainly mentions how the complicated grid structure is a source of particular worry, and that microgrids were established to address this issue. Electric grids are vulnerable to malicious attack and cyber threats nowadays, thus their security is a must. They are enormous in size and are frequently found far from densely populated areas.

The prevalence of obesity has been increasing globally as one of the major health issues due to the increased calorie intake and decreased physical activity. Dietary restriction has been proved to induce changes in various biological processes. The present study was aimed to observe the effect of complete and intermittent fasting in obesity induced model rats by analyzing biochemical, and histological parameters. Twenty four Wister rats of either sex aged about twelve weeks were used for study. They were divided control, obese, complete fasting(CF) and intermittent fasting (IF). Other than control group, the remaining three groups were given obesogenic diet for six weeks . The IF and CF groups were given 2 different fasting regimens for two weeks. After the experimentation procedures the blood samples were collected and liver and pancreatic tissues was dissected for biochemical and histological analysis . The Data was analyzed using SPSS-16, Kruskal-Wallis test. Results were expressed as median with interquartile range p<0.05 was expressed as statistically significant. Obesity induced increase in the lipid peroxidation was observed in the pancreatic (p<0.05 and liver tissue (p<0.01) when compared to control group. Decreased level of anti-oxidants was observed in the pancreatic tissue (p<0.01) in the obese group .In both the fasting groups, decreased malondialdehyde (MDA) level and increased glutathione (GSH) was observed in the liver and pancreas. Comparatively, CF group showed lower MDA(p<0.01) in both liver and pancreas and higher(p<0.01) antioxidant in liver as compared to IF. Complete fasting group also showed a better histological profile. Complete fasting produced a better oxidative profile in the liver and pancreas when compared to Intermittent fasting group .The present research proves that simple diet control regime could be helpful in decreasing the pathophysiology associated with the obesity.

Published: January 2023

The anti-inflammatory potential of methanol and ethyl acetate fractions of Sesbania grandiflora Linn., roots were evaluated by carrageenan induced rat paw oedema method and cotton pellet induced granuloma in rats. Female Wistar rats were treated orally with methanol (MFSGR) and ethyl acetate (EAFSGR) fractions of Sesbania grandiflora roots (100 and 200 mg/kg) and Diclofenac sodium (15 mg/kg). One-hour post treatment, Carrageenan (0.1 ml of 1 % w/v, s.c.) was administered in the sub plantar region of the left hind limb of rat. Thereafter, paw volume was measured at 0, 30 min, 1, 2, 3 and 4 h. Percentage inhibition (PI) of oedema was calculated. In cotton pellet-induced granuloma model, male Wistar rats were treated with Diclofenac sodium (10 mg/kg, p.o.) and MFSGR and EAFSGR (100 and 200 mg/kg, p.o.) respectively. Thirty-minutes after respective treatment, an autoclaved cotton pellet of 20±1 mg was aseptically implanted subcutaneously. Fraction and standard diclofenac were administered once daily for the next 7 days. On 8th day, excised cotton granuloma was dried and weighed, body weight and organ index were calculated. MFSGR and EAFSGR (100 and 200 mg/kg) exhibited a significant inhibition in paw volume against carrageenan-induced paw oedema. In cotton pellet induced granuloma model, MFSGR and EAFSGR exhibited significant inhibition of cotton dry and wet weight. The present study suggests that the methanol and ethyl acetate fractions of Sesbania grandiflora roots exhibit anti-inflammatory activity. The observed effect could be attributed to the presence of vital phytoconstituents.

Published: January 2023

Aims and Objectives: The aim of this study is to assess basic knowledge about dental implants amongst newly graduated dental practitioners at the Ajman and Sharjah Dental schools. Materials and Methods: This study was carried out by a self-designed, close-ended questionnaire which was given to the participants in both Ajman and Sharjah dental schools. The questionnaire consists of three parts (knowledge, attitudes and practice) with respect to implant dentistry, and was filled by 173 dentists. Consequently, the data was analyzed by (SPSS, 22V) to reveal the study results. Results: The study revealed that 81.78% of the participants were aware about the various dental implant systems, the surgical techniques involved in dental implant placement, the distance between two adjacent implants, and the different anatomical structures that should be avoided during implant placement. However, 66.5% of the participants did not display full awareness (proper understanding) of dental implant contraindications. Most dental practitioners were aware of immediate and delayed implant placement and their loading protocols. Despite the difficulty of the dental implant procedure, 89% of the participants were willing to present implants as a treatment option to their patients, 87.9% would incorporate implant treatment into their future practice and the majority of them (98.3%) agreed to replace their missing mandibular 1st molar by a dental implant. The participants believed that the difficulties of the dental implant procedure are related to the skill level of the practitioner, lack of proper instrumentation and materials required for the dental implant procedure, and also related to cost (74.6%,63.6%, 83.8%) respectively. Out of all the dental practitioners who took part in this study, only 27.7% of them have undergone formal training in dental implant placement and only 54.3% were satisfied with the implant education they received at undergraduate level. Therefore, 94.8% of the participants demanded further education and training with respect to dental implant placement. Regarding implant education levels, 66.5% of the dental practitioners stated that implant education and training methods are rendered more beneficial at post-graduate level, whilst only 33.5% stated that implant education and training methods are best at undergraduate level. Conclusion: Study findings revealed that dental practitioners possess a high level of knowledge and education towards dental implants, however the overall results show that participants lack practical experience. Therefore, further progress is needed on all educational levels, in addition to advanced level training of dental implant placement for the purpose of enabling dentists to carry out dental implant procedures with a higher level of confidence.

Published: January 2023

Background: Medical and dental students are among the frontline workers in the battle against COVID 19. As such their vaccination is mandatory. We conducted this study to assess perception and attitude of medical and dental students towards COVID-19 disease and its vaccination. Methods: A total of 185 medical and 170 dental students were included in our study. A questionnaire based on previous studies was prepared. The respondents were interviewed telephonically and appropriate responses were recorded. Results: Among 355 students enrolled in our study, higher percentage of dental students were infected with COVID-19 (26%) as against only 20% medical students. 60% dental students had been tested for COVID-19 as against 70% medical students. Majority students in both the groups had done rapid antigen test (RAT). Academic loss was the major COVID-19 disease related concern among medical students, while in dental group there were two major concerns i.e academic loss and fear of passing the infection to family. Both the groups feared anaphylaxis the most as a sequel of vaccination. The other vaccination concerns in both the groups were fever, myalgias, infertility, thrombus formation while few female students feared that vaccination may disturb their menstrual cycles. The preferred vaccine in both the groups was Covishield. Conclusion: Our study concluded that there are many hurdles in the path of vaccination even among medical and dental students. It is important to address these hesitancies especially among health care workers since their opinion and recommendation is held supreme by common masses.

Published: January 2023

The article presents a case study on the modeling of heat transfer parameters through transparent construction elements. Conducting experimental studies on the scale of an entire building is very complex, on the one hand due to the size and geometric complexity of the studied objectives and, on the other hand, due to numerous random factors (climatic conditions or how the buildings are operated). In order to be able to carry out a study on the real behavior of the buildings, models are made for them, taking into account the real mode of operation of the installations related to these constructions. The present article consists in making a modeling for a simple exterior window, with a single sheet of glass that separates the interior space of an enclosure (rooms) from the exterior environment. The modeling will be performed both for the case of a building located inside a locality and for the case of the location of the building outside the locality.
Exhaustive Optimization Method Applied on Electromagnetic Device
Authors:   University of Craiova, Dolan Alin-Iulian
Published: January 2023

This paper presents the application of an exhaustive optimization method based on the design of experiments (DOE) and the finite element method (FEM), with the aim of improving the actuation force developed by a DC electromagnet. The optimization of this device has been the subject of several previous works, allowing comparisons between the optimization methods applied in terms of the obtained precision and the workload. According to previous studies, two geometric parameters (the angle ratio of the support tip and the coil shape ratio) are very influential on the force developed at the maximum air gap. Thus, the exhaustive optimization method took into account these two parameters for its maximization, having as constraints the maintenance of the global dimensions of the device (external radius, the height of carcass, height of the plunger with support) and of the cross-section of the winding. The optimization algorithm used the results of 2-D FEM numerical experiments carried out with the FEMM program in combination with the LUA language and is based on the response surface methodology (RSM) and analysis of variance (ANOVA). Second-order polynomial models of the objective function were calculated using full factorial designs with three levels per factor. After three iterations, a very good result was obtained, comparable to those obtained by other methods, but with a significant cost in terms of workload, the optimum obtained being a global one.

Students’ response to the introduction of active learning and computational practices in a bachelor-level earth science course
Authors: Møller Tor Einar , Kvarøy Serianna , Hannisdal Bjarte
Published: January 2023

Earth science education should provide space for students to engage with real-world problems involving complex earth systems and their societal implications. However, the ill-structured nature of such problems creates uncertainty among both teachers and learners. To explore the effect of this uncertainty, we designed and taught a bachelor-level earth science course that introduced geology students to computational practices allowing them to work with authentic data, methods, and ill-structured problems. In addition, the course was designed entirely for active learning and formative assessment. Students provided reflection notes as part of every learning activity, and a series of focus group interviews were conducted at the end of the course to triangulate student experiences with computational practices and problem solving in groups. Our findings suggest that the introduction of computational practices to novices, combined with the transition from passive to active forms of learning, were major sources of uncertainty. This uncertainty needs to be understood and confronted in order for students to engage with real-world problems in an effective manner. On the other hand, our results indicate that collaborative work in groups can alleviate some of the effects of this uncertainty. Our study also supports the systematic use of student reflections as a means of fostering feedback literacy among students as well as teachers.

Published: January 2023

Azerbaijan is one of the oldest oil and gas producing regions in the world. Industrial development of oil fields has been started here since the second half of the 19th century. The article examines the current state of the fields that have been under development for a long time and identifies modern problems. Solutions to these problems have been explored. Our research objects are Darwin Bank, Pirallahi Island and Gurgan-Deniz fields on the Western Absheron-South anticline line. All three fields have been under development for a long time and have sufficient residual reserves. The study of the current state of oil and gas fields, which have been under development in our country for a long time, shows that it is necessary to take the right approach to identifying ways of efficient use resources. During the development process, the geological parameters of oil and gas fields are subject to certain changes. These changes can be both regular and in various forms. Issues that are important for the effective completion of the long-term development of oil and gas fields which we researching have been studied and identified. Geological-geophysical data were collected and systematized to clarify the structural-tectonic, lithofacial features and substantiate the ways of effective development of resources. The geological structure and structural tectonic features of the deposits have been clarified and structural maps have been compiled. 3D geological model of the deposits has been compiled, lithofacial features have been determined and lithofacial model has been constructed. The characteristics of tectonic faults were determined, the reserves were redefined and geological risks were assessed.

In the article reflects the tasks of specifying the geological structure of the site as a result of the analysis of two-dimensional (2D) seismic survey data carried out in the Bulla-deniz area. On the basis of the studies carried out, the shape and dimensions of the Bulla-deniz structure, the planned state and amplitudes of tectonic faults were specified. It has been established that the structure is elongated in the NW-SE direction and changes its direction to the east in the area of the mud volcano. The seismic profile sections show that the seismic record is represented by a weak, sometimes chaotic, complex wave pattern due to the activity of a mud volcano and disjunctive disturbances in the area representing the southern crest part of the structure. There is rarefaction of isohypses from the northern crest part of the Bulla structure in the direction of the SE and NW of the pericline.

Riesgo de incendio y arquitectura en madera en Valparaíso. 1838-1906
Authors: Arango López Diego
Published: January 2023

Este artículo analiza la relación entre la arquitectura en madera y el riesgo de incendio en la historia de Valparaíso. Se plantea que el auge comercial y económico de la ciudad-puerto favoreció la construcción en madera y a su vez generó un panorama inflamable que contribuyó al desarrollo de una noción local de riesgo de incendio. Asimismo, los resultados de la investigación demostraron que el manejo del riesgo de incendio requirió de medidas de mitigación que se fueron instalando progresiva pero desigualmente en la ciudad. Éstas, además, resultaron en nuevas técnicas de construcción desarrolladas por habitantes y constructores locales y que correspondían con las capacidades económicas de sus dueños y con las dinámicas comerciales de la ciudad. Por último, el artículo se interesa por la disponibilidad de la madera en la ciudad y demuestra los vínculos y fracturas que generaba construir con base en un material importado.

La urbanización al sur de Santiago, realizada entre 1890 y 1930, representa un caso particular en el contexto de la periferia capitalina, al constituirse como el principal barrio industrial de la ciudad en la época. Dicha zona estuvo asociada a complejas condiciones de habitabilidad, producidas por externalidades negativas propias del mundo fabril, como también por la convivencia con la cloaca máxima de la zona sur, el Zanjón de la Aguada. En este contexto, postulamos que este proceso de crecimiento urbano estuvo marcado por tres ejes: el emplazamiento del Matadero de la ciudad, la extensión del Ferrocarril de Circunvalación (FFCC) y su convivencia con numerosas poblaciones de trabajadores. A través de fuentes oficiales, de prensa, de imágenes cartográficas e iconográficas, se indagará en estos fenómenos, observando un problema compuesto por diversas escalas y en el que intervinieron distintos protagonistas. De esta forma, una de las conclusiones de este artículo es que el desarrollo de estos tres elementos marcó aquel paisaje urbano, definiendo los modos de habitar de su población y el proceso de expansión de Santiago.

Background: A severe acute respiratory virus that started lethal lung infections in Wuhan, China in Dec 2019 swiftly evolved into an epidemic in March 2020. Millions of fatalities have been attributed to COVID-19 globally, and people who survived the acute type often experience major mortality. Objective: The purpose of this research was to describe a number of patients who had experienced pulmonary problems following COVID-19. Methods: From December 2021 to June 2022, a retrospective research was done in Hayatabad Medical Complex, Peshawar. Patients with a record of a COVID-19 diagnosis verified by nasopharyngeal RT-PCR and who had been hospitalized to or visited an outpatient department were included. Results: This research included a total of 50 COVID-19 infected individuals. patients most frequently reported shortness of breath (n=29; 58%), fever (n=7; 14%), cough (n=5; 10%), and hemoptysis (n=9; 18%). Major surgical treatments were carried out on them, including bullectomies, lobectomies, and decortications and the most successful treatment for empyema is open decortication. Thirteen patients (26%) were admitted to the ICU after operations, nine cases (18%) acquired mucormycosis, and two deaths were reported.

Objective: To estimate the prevalence of PCOS, a clinically noticeable disorder in women that causes excessive development of coarse or dark hair on the face, chest, and back in a male-like pattern, between first-degree female relatives in families with a proband who has the condition. Methods: A history of oligomenorrhea, hirsutism or biochemical proof of hyperandrogenism (raised entire or free T) and other illnesses were used to diagnose PCOS. Moreover, for better results, Study participants through PCOS (age 24.3G5.8 years, Body Mass Index 26.8G6.9 kg/m2) were used for better results. An R8-modified Ferriman-Gallwey score was used to characterize hirsutism. Results: 24% of the mothers and 32% of the sisters among the moms and sisters assessed had PCOS, respectively. Only premenopausal women who were not receiving treatment i.e., moms (35%) and sisters (40%) for PCOS were found to have the condition, which is consistent with symptoms becoming better due to hormone therapy or age. These PCOS prevalence percentages are much greater than the illness's frequency in the normal community (about 4%), which points to a considerable hereditary component. Furthermore, in comparison to female without hirsutism, hirsute female were pretty young, had greater BMIs, and also had greater amounts of circulatory androgens.
