Published: June 2023

The literature on conventional irrigants used as root canal disinfectants in endodontic is extensive. For smear layer removal, a number of chelating compounds comprising citric acid and ethylenediaminetetraacetic acid have been utilized. Both work by lowering the dentin complex’s calcium ion content, which changes its permeability. Although synthetic antibiotics have proven unsuccessful against a number of pathogenic species due to rising drug resistance, attention to antimicrobials derived from plants has been evident in the recent literature. As literature is boosting about the various time-tested herbs, there are still other heritage herbs that remain away from the limelight. Hence, this review focuses on various studies that highlighted the use of herbal irrigants in place of synthetic irrigants. Search methodology involved searching PubMed and Google Scholar databases for articles that were published between 2018 and 2022, following which 13 articles were recruited for the current review. After evaluation of the various studies, the review concluded that herbal irrigants are useful root canal irrigants that can replace synthetic irrigants for smear layer removal and antimicrobial efficiency against various microorganisms.

Authors: Yadav Manjusha , Kose Varsha D. , Vijay Nikita R. , Dwidmuthe Kanchan Samir
Published: June 2023

The most prevalent endocrine issue affecting women is thyroid dysfunction. Thyroid hormone has a significant effect on women’s life. Its dysfunction is widespread, particularly among women over 50. Understanding how thyroid disease’s clinical symptoms change with ageing is crucial when treating peri- and post-menopausal women. Considering that 30% of India’s population is female, the thyroid disease epidemic appears to affect Indian women more than any other ailment. Detection of frequency of thyroid disorder in pre- and post-menopausal women and its association with menopausal symptoms. This scoping review was done using Preferred Reporting Items for Systematic reviews and Meta-Analyses-extension for Scoping Reviews guidelines. Database searches in Pub Med, Web of Science, and Scopus were done. The research question was clarified and modified using keywords. After database searches 10 relevant articles were obtained and were included in this study. A meta-analysis method and extra analytical research carried out in tertiary care center were used to synthesize the findings. Compilation of data extracted from different previous studies done which showed frequency of thyroid hormone changes in women in pre- and post-menopausal age groups from which the conclusion of the present study made. This scoping review highlighted that thyroid hormone dysfunction needs to be correlated to menopausal symptoms. As thyroid hormone dysfunction is common in peri- and post-menopausal age groups, which was seen in many articles that we have reviewed, its correlation to menopausal symptoms is more important. Thyroid disorders can be detected and treated early and improve quality of life. Future research on this correlation is required which was not found in current articles.

Authors: Uppal Simran , Chowdhry Aman , Kapoor Priyanka , Dar Dhruv
Published: June 2023

Introduction:

Dentists are prone to ocular injuries from chemical, physical, or infectious agents. While most dentists wear masks, gloves, and gowns, eye protection continues to be neglected. Thus, this study was undertaken to identify these gaps in awareness and practices of eye safety among dentists.

Aim:

This study aims to evaluate and compare the knowledge and practices of hospital and private dental practitioners regarding eye protection in clinical practice.

Methodology:

A questionnaire designed to assess the eye safety knowledge and practices of dentists was validated and mailed to hospital dental practitioners and private dental practitioners (100 each), from the National Capital Region over 6 months. Data collected were subjected to Chi-square analysis for comparing knowledge and practices of the two groups.

Results:

Dentists were found to be lacking in their practices with 48.5% using eye protection sometimes and 5.5% never using it, although their knowledge however revealed otherwise. Sixty-eight percent of dentists never or rarely used eye protection for their patients. 40.5% dentists had at least one incident of ocular trauma due to inadequate eye protection while 26% had at least 5 such incidents.

Conclusion:

The study highlights the gaps in the knowledge and practices of dentists regarding eye protection thus, emphasizing the need for creating more awareness, more so in the coronavirus disease of 2019 era, to prevent further transmission of infections.
Neurovascular Compression Syndromes: A Pictorial Essay
Authors: Parihar Pratapsingh H , Mishra Gaurav Vedprakash , Shetty Neha Dinesh , Bora Nikita , Bhagyasri Nunna
Published: June 2023

Neurovascular compression syndromes are typically brought on by arteries that come into contact with a cranial nerve’s (CN) cisternal section. Neurovascular contact does not always present with clinical symptoms. The most susceptible area for symptomatic neurovascular compression syndromes is the transitional zone between the peripheral and central myelin. Individual CN functional abnormalities are the clinical hallmark of neurovascular compression disorders. We present a series of four cases of patients presenting to a tertiary care center in Central India with symptoms and signs of neurovascular compression syndrome.

Authors: Shahrouzi Mohammad , Ferreira Jorge , Tahamtani Faramarz
Published: June 2023

This study aims at investigating the global existence, asymptotic stability and blow up of solutions for a nonlinear viscoelastic fourth-order (p(x), q(x))-Laplacian equation with variable-exponent nonlinearities. First, we prove the global existence of solutions, and next, we show that the solutions are asymptotically stable if initial data p(x) and q(x) are in the appropriate range. Moreover, under suitable conditions on initial data, we prove that there exists a finite time in which some solutions blow up with positive as well as negative initial energies.

Published: June 2023

CI engines provide higher thermal efficiency compared to other internal combustion engines. On the other hand large amounts of smoke and NOx are produced during combustion. Smoke and NOx can be reduced by applying Premixed Charge Compression Ignition (PCCI) combustion. Unfortunately, the problems of PCCI combustion include unstable start of combustion and limited operating range. The multi-pulse ultrahigh pressure injection allows fuel to control PCCI combustion. The objective of offset orifice nozzle is to improve mixture formation and shorten spray penetration in order to increase thermal efficiency and control PCCI combustion. The offset orifice nozzle was designed by shift orifice aliment from into the sac center to edge of sac follow swirl direction. Counter bore design was applied to offset orifice nozzle in order to keep the constant orifice length as standard nozzle. This paper investigates the effect of nozzle orifice design on combustion characteristics under multi pulse ultra high pressure injection and PCCI combustion conditions. The experiments were carried out on a single cylinder engine at 0.55 MPa gross IMEP at 1,750 rpm. The injection pulses were 3 pulses equally mass main injection at 150, 200, 250, 300 and 350 MPa injection pressure. In case of standard nozzle orifice, 1st, 2nd pulse are PCCI followed by diffusive combustion in every injection pressure. For offset orifice nozzle orifice at 150 and 200 MPa 1st, 2nd pulse are also PCCI combustion. However when injection pressure is over 200 MPa, the 2nd pulse of rate of heat release become diffusive combustion. The offset orifice nozzle resulted in increased thermal efficiency, NOx and smoke. However significant differences between the smoke of offset orifice nozzle and standard nozzle were not found under injection pressure 300 and 350 MPa. The offset orifice nozzle also resulted in decrease CO and THC.
Modeling Subjective Evaluation of Instantaneous Sound Qualities of Motorcycle Exhaust Sound Applying a Highly Efficient Experimental Design

Published: June 2023

Exhaust sound quality is one of the most important factors for attractive motorcycles. It is desirable to quantitatively and objectively examine the exhaust sound quality during the development process.

In our previous study, we developed evaluation models that could be applied to various exhaust sounds. However, due to the limitation of the model, it could not be applied to varying conditions, such as from acceleration to steady driving and then to deceleration. In this study, we developed more practical evaluation models that can be applied to various driving conditions.

To cover a wide variety of sounds under different driving conditions, we prepared more than 300 sound stimuli and collected subjective evaluation data on those sounds. As the evaluation method, we used a pairwise comparison method to make decision making easy for the participants. However, if the pairwise comparison was simply performed for such sample size, the experiment cannot be done in a realistic experimental scale because the number of evaluation pairs gets very large. To solve this issue, we allocated evaluating pairs among multiple participants and used the Bradley-Terry model for estimation of the subjective quality rate. With these methods, the number of evaluations per participant was reduced to 1/300 of that required with the naive method.

We constructed the models based on a multiple regression analysis on the subjective evaluation data with waveform feature values as independent variables. We confirmed that these models accurately predicted the motorcycle developers' subjective impression of the exhaust sound of actual vehicles under a wide range of driving conditions.

Published: June 2023

Low temperature plasma ignition has been proposed as a new ignition technique as it has features of good wear resistance, low energy release and combustion enhancement. In the authors’ previous study, lean burn limit could be extended by low temperature plasma ignition while a voltage drop during discharge, leading to the transition to arc discharge, was found. In this study, the structure of plug and power supply’s performance with steep voltage rising with time, dV/dt, are examined to investigate the effects on combustion performance. As a result, comparing three power sources of conventional, IES and steep dV/dt, steep dV/dt showed small cycle-to-cycle variation and shorter combustion period, leading to higher peak value of the rate of heat release and better indicated thermal efficiency by relatively 6% and 4% compared to CIC and IES, respectively.
Generation of Mission-Based Driving Cycles Using Behavioral Models
Parameterized for Different Driver Categories
Authors: Kharrazi Sogol , Nielsen Lars , Frisk Erik
Published: June 2023

A methodology for the generation of representative driving cycles is proposed and
evaluated. The proposed method combines traffic simulation and driving behavior
modeling to generate mission-based driving cycles. Extensions to the existing
behavioral model in a traffic simulation tool are suggested and parameterized
for different driver categories to capture the effects of road geometry and
variances between drivers. The evaluation results illustrate that the developed
extensions significantly improve the match between driving data and the driving
cycles generated by traffic simulation. Using model extensions parameterized for
different driver categories, instead of only one average driver, provides the
possibility to represent different driving behaviors and further improve the
realism of the resulting driving cycles.

Authors: Bellini Emanuele , Gerault David , Grados Juan , Makarim Rusydi H. , Peyrin Thomas
Published: June 2023

In this paper, we present an improved differential-linear cryptanalysis of the ChaCha stream cipher. Our main contributions are new differential-linear distinguishers that we were able to build thanks to the following improvements: a) we considered a larger search space, including 2-bit differences (besides 1-bit differences) for the difference at the beginning of the differential part of the differential-linear trail; b) a better choice of mask between the differential and linear parts; c) a carefully crafted MILP tool that finds linear trails with higher correlation for the linear part. We eventually obtain a new distinguisher for ChaCha reduced to 7 rounds that requires 2166.89 computations, improving the previous record (ASIACRYPT 2022) by a factor of 247. Also, we obtain a distinguisher for ChaCha reduced to 7.5 rounds that requires 2251.4 computations, being the first time of a distinguisher against ChaCha reduced to 7.5 rounds. Using our MILP tool, we also found a 5-round differential-linear distinguisher. When combined with the probabilistic neutral bits (PNB) framework, we obtain a key-recovery attack on ChaCha reduced to 7 rounds with a computational complexity of 2206.8, improving by a factor 214.2 upon the recent result published at EUROCRYPT 2022.
Optimally Secure Tweakable Block Ciphers with a Large Tweak from n-bit Block Ciphers
Authors: Shen Yaobin , Standaert François-Xavier
Published: June 2023

We consider the design of a tweakable block cipher from a block cipher whose inputs and outputs are of size n bits. The main goal is to achieve 2n security with a large tweak (i.e., more than n bits). Previously, Mennink at FSE’15 and Wang et al. at Asiacrypt’16 proposed constructions that can achieve 2n security. Yet, these constructions can have a tweak size up to n-bit only. As evident from recent research, a tweakable block cipher with a large tweak is generally helpful as a building block for modes of operation, typical applications including MACs, authenticated encryption, leakage-resistant cryptography and full-disk encryption.We begin with how to design a tweakable block cipher with 2n-bit tweak and n-bit security from two block cipher calls. For this purpose, we do an exhaustive search for tweakable block ciphers with 2n-bit tweaks from two block cipher calls, and show that all of them suffer from birthday-bound attacks. Next, we investigate the possibility to design a tweakable block cipher with 2n-bit tweak and n-bit security from three block cipher calls. We start with some conditions to build such a tweakable block cipher and propose a natural construction, called G̃1, that likely meets them. After inspection, we find a weakness in G̃1 which leads to a birthday-bound attack. Based on G̃1, we then propose another construction, called G̃2, that can avoid this weakness. We finally prove that G̃2 can achieve n-bit security with 2n-bit tweak.

Published: June 2023

Research in the field of animal nutrition has recently begun to pay more attention to biologically active substances in plants, calling them Phytobiotics for growth and health and disease management of animals. Phytobiotics are plant derived products added to feed for their beneficial effect on gut, immunity, health, growth and performance. Phytobiotics from Garlic, Pepper, Neem, Turmeric, Ginger etc, have been used as plant doctors to treat ailments since time immemorial. These seem to be substituting the antibiotics with better treatment efficiency and zero side effects. The beneficial effect of these Phytobiotics can be attributed to activation of feed intake, secretion of digestive juices and enzymes, immunity enhancement, anti oxidant , anti inflammatory and anti microbial (viral, bacterial, protozoan etc) properties. These Phytobiotics have influenced the economics of production too attributing to a 30% reduction in production costs, management friendly with a safe environ for the animal and its end consumer the human.

Strengthening the Choice for a Generic Qualitative Research Design
Authors: Ellis Jeri , Hart David
Published: June 2023

Supporting the choice for research using a generic qualitative design is needed to assist the researchers with helpful guidance and descriptions about the approach in research. The name “generic” can be rather obtuse. Determining its appropriateness goes beyond discussions about combining elements of other traditional qualitative designs and considers the generic approach as a standalone methodology. Despite its inherent flexibility, the strength of the generic design offers a view of descriptive research data for interpretation that includes personal meaning making in research and is particularly well suited for counseling and other social sciences. The strengths, benefits, and limitations of the generic design are reviewed to assist the researchers in their selection of a generic qualitative research methodology and further the professional literature with increased knowledge and understanding. Counseling professionals benefit from the generic design because of its exploratory nature into real world experiences as perceived by those who live them.
“As If I Use a Filter, and It Has Become a Part of Me”: Discriminatory Workplace Experiences of Lesbian and Gay Employees of India
Authors: Maji Sucharita , Singh Tushar , Hooda Meghna , Sarika Kumari
Published: June 2023

In 2018, the Indian penal code scrapped section 377 and decriminalized consensual homosexuality. However, there exists a significant knowledge gap regarding what extent Indian workplaces have been successful in ensuring a discrimination-free environment for lesbian, gay, bisexual, transgender, and queer (LGBTQ) employees. Thus, to address this gap, the current study explored discriminatory workplace experiences encountered by Indian lesbian and gay (LG) employees. The qualitative data has been collected through semi-structured in-depth interviews and analyzed through the thematic analysis method. A hybrid of the inductive and theoretical thematic analysis revealed four themes, that is, subtle discrimination, disclosure dilemmas, dressing and appearance norms, and gender-binary filter. LG employees frequently encounter workplace discrimination in subtle forms (distancing, excluding, commenting behind the back, and dignity-attack). Experiences of discrimination and fear of going through workplace discrimination lead to disclosure dilemmas, that is, a multilayered decision-making process involving strategy formation, risk perception, and fear of discrimination while choosing/ not choosing whether/how/where/when to disclose sexual identity at the workplace. Also, to establish heteronormativity, Indian organizations often maintain strict dress and appearance norms. In addition to these externally employed norms, LG employees use a gender-binary filter to screen their behaviors, gestures, speech (content, tone, pitch), walking, and dressing to confirm they align with the gender binary and to avoid workplace discrimination. Thus, the study shows that in Indian organizations, the workplace experiences of LG employees are far from discrimination-free. The organizations can use the study findings to understand current affairs and develop policies to ensure an inclusive workplace for LG employees.
Peeling Away the Taken-For-Grantedness of Research Subjectivities: Orienting to the Phenomenological
Authors: Freeman Melissa , Muhammad E. Anthony
Published: June 2023

Qualitative research is a multidisciplinary field of practice that acknowledges and values the situatedness and subjectivities of the researcher. Therefore, reflexively accounting for one’s subjectivities is a crucial part of a research report. Less discussed is how subjective understandings are historically, culturally, and socially mediated, often challenging researchers’ abilities to orient themselves critically to this self-reflective undertaking. Phenomenology is a philosophical approach investigating how phenomena such as subjectivity are constituted in experience. This makes phenomenology an essential resource for understanding how complex subjective responses manifest differently depending on one’s orientation to the situation. This paper aims to familiarize qualitative research instructors and learners with a series of phenomenological activities that have proven helpful in disclosing multiple ways subjectivities are historically and contextually mediated, embodied, and technologically modified.

Published: June 2023

This study is aimed to report the perspective of people with V.I about their use of spatial representation(cognitive maps) for determining the support level and applicability of cognitive maps while traveling on real routes. This research utilized the methodology of qualitative research in the form of semi structured interviews in order to obtain insights of persons having visual impairment about their navigation in different environments. The interviews were conducted with 20 persons having visual impairment working in different fields of life. The data analysis was done through thematic analysis approach. The participants were intended to answer the questions about the representation and understanding of space, the support level of these representations while traveling, and the role of other senses for successful navigation. The results showed that persons having visual impairment do have spatial representation and the creation of spatial representations does not require visual experience. The study suggested the strong need to assess the way in which persons having visual impairments develop cognitive maps of their environment because it is extremely significant both theoretically and practically and throws light on the role of sensory modalities in the development of mental mapping skills which can in turn recommend how spatial developments might be nourished.
An Economic Appraisal of Blockchain’s Impact on Finance and Market Competition
Authors: Lee Gunhee , Kim Ted
Published: June 2023

This paper provides an economic appraisal of blockchain technology's impact on the two representative pillars of an economic system: finance and market competition. It is argued that although cryptocurrencies designed upon blockchain technology are perceived as alternative currencies and speculative financial assets today, their roles are limited in the economic sense. However, blockchain technology can promote market competition in the internet sector by the virtue of decentralization. In comparison to the highly concentrated market power of current internet companies, new dynamics of market competition based on Web3 are discussed.

A 55-year-old female presented with history of pain in the right hypochondrium along with complete loss of facial and scalp hair over last two months. On evaluation, she was found to have locally advanced, synchronous malignancies of the gallbladder and head of the pancreas. Synchronous malignancy of gallbladder and pancreas is in itself very rare and less than 10 such cases have been reported in the world literature. Alopecia totalis has been classically associated with various autoimmune disorders. However, alopecia totalis as a presenting feature of any abdominal malignancy has never been reported in the medical literature. The present report describes a rare association of synchronous pancreatobiliary malignancies with strange clinical presentation.
Single vs. double drain in modified radical mastectomy: A randomized controlled trial
Authors: Khan Salma , Khan Momna , Wasim Asma
Published: June 2023

Objective: It was aimed to test the hypothesis that the use of a double drain results in less seroma formation, duration of the hospital stay, surgical site infection (SSI), postoperative pain, hematoma, flap necrosis compared to a single drain in patients undergoing modified radical mastectomy.

Material and Methods: This parallel-group, single-institution randomized controlled trial was conducted at the department of surgery of our institute between April 2015 and July 2018. Women undergoing modified radical mastectomy were randomly allocated to either a single drain (n= 98) or double drain (n= 98).

Results: Both groups were comparable for baseline variables such as age, co-morbidity, BMI, and tumor characteristics. The variables of single drain yielded no better outcomes compared to double drain with estimated blood loss (101.67 ± 25.14 vs.101.67 ± 24.40, p> 0.001), drain volume (898.81 ± 116.42 vs 803.97 ± 103.22 mL, p> 0.001), duration of surgery in minutes (103.19 ± 15.96, 103.19 ± 15.93) and seroma formation (13.4% vs 6.1%, p= 0.082). However, single drain yielded less postoperative pain (mean 2.5 ± 0.70 vs 5.22 ± 5.10, p< 0.000). On multivariable Cox regression analysis, single drain was associated with a lower risk of significant postoperative pain [adjusted relative risk 0.14 (95% confidence interval (CI) 0.070-0.25)] and overall complications [adjusted relative risk 0.47, (95% CI 0.26-0.86)]. On multiple linear regression, the duration of drains in the single drain group was 0.01 days less than double drain (r2= 0.00, b= 0.388, p> 0.001).

Conclusion: The use of a single drain significantly reduces postoperative discomfort and pain while demonstrating similar morbidity to the patient with two drains. We thus recommend preferential use of a single drain in modified radical mastectomy (NCT02411617).

Objective: Pathological complete response (pCR) occurs in about 20-30% of patients undergoing systemic neoadjuvant therapy. This leads to the idea of sparing the patient the morbidity associated with axillary surgery. “Wait and watch” policy for cancers which achieve complete pathological response on neoadjuvant systemic therapy is a well-established practice in various cancers like the esophagus, rectum and larynx. This has led to organ preservation protocols being practiced worldwide for these cancers without affecting the overall survival of the patient. We believe patients undergoing a complete pathological response in the breast may be spared axillary surgery. Axillary surgery leads to morbidity and extra financial burden with no added advantage in survival.

Material and Methods: A total of 326 patients with breast cancer who had received neoadjuvant systemic chemotherapy from 2015 to 2020 were included in our retrospective study. Final histopathology of the breast and axillary surgery was noted to report the frequency of complete pathological response. The frequency of positive nodal disease with respect to stage, grade and type of cancer was measured.

Results: Among 326 patients, our study showed that 53% of patients with complete pathological response in breast also had complete response in the axilla compared to 43% with incomplete pathological response. No significant difference was found for age, menopausal status, initial tumor size when patients with complete pathological response were compared to non or partial responders. The rate of complete pathological response was higher in patients with clinically node negative patients after NACT, hormone negative, HER2 positive and triple negative population.

Conclusion: Our results indicated that 53% of the patients who developed complete pathological response in the breast underwent needless axillary procedure. Axillary surgery can be staged after the breast surgery if residual tumor is present on the histopathological specimen. In case of pCR, omission of axillary surgery can be considered. However, a larger population, multi-centric studies are needed for treatment guidelines.

Objective: Hyoscine-N-butylbromide is used by some surgeons during laparoscopic sleeve gastrectomy (LSG) to loosen gastric smooth muscles and to provide a more effective LSG. However, evidence-based data on the effects of hyoscine-N-butylbromide in laparoscopic sleeve gastrectomy are limited and its effect on sleeve gastrectomy surgery and weight loss is unknown. The aim of this study was to analyze the effect of intraoperatively administered hyoscine-N-butylbromide on stomach resection volume, weight loss and complications seen in patients undergoing LSG.

Material and Methods: Patients who underwent laparoscopic sleeve gastrectomy due to morbid obesity were included in the study. Intraoperative hyoscine-N-butylbromide was administered to 52 patients (Group 1), not applied to the other 52 patients (Group 2). Age, sex, height, weight and body mass index (BMI) data of the patients were obtained retrospectively. The weight, BMI, percentage of total weight loss (TWL%) and percentage of excess weight loss (EWL%) of the patients were evaluated at postoperative third, sixth and 12th months.

Results: Resected gastric volume (p= 0.111), length of stapler line (p= 0.944), operation time (p= 0.383), hospitalization time (p= 0.494) and postoperative complications (p> 0.05) did not differ between Groups 1 and 2. However, frequency of intraoperative tachycardia (p< 0.001) and hypotension (p= 0.006) in Group 1 was significantly higher than in Group 2. TWL% and EWL% values were similar between the two groups at all-time points. Stapler line leakage was not observed in any patient during the postoperative period.

Conclusion: Intraoperative hyoscine-N-butylbromide use is not effective on weight loss postoperatively in patients undergoing LSG. Although hypotension and tachycardia occured in some of patients, none of the patients had complaints in the early or long-term postoperative period. The use of hyoscine-N-butylbromide during LSG is safe but does not have any effect on weight loss.

Published: June 2023

New ventures are source of innovation and change, although there are many success cases many new ventures quite before they have fulfilled their potential. Despite the growing number of business incubation amenities, the area of incubators and new venture creation is understudied. The goal of this study was to investigate the role of business incubators on new venture creation in Kenya. This study was underpinned by the Economic theory of Mark Casson, Schumpeter’s theory of Innovation, Dynamic Capability View and Theory of Business Incubators. The study used desktop analysis of existing literature on business incubations and new venture creation. The study found that business incubators are critical in naturing and developing new ventures and they are also effective in new venture creation. Several studies have focused primarily on the exterior perspective, ignoring the interior perspective, in which the entrepreneur plays a significant influence. Moreover, the studies on business incubators and the development of new ventures have been conducted in industrialized nations, yet only a few have been conducted in developing nations. Most of the study on business incubators and new venture creation had employed single research design and thus no single design is perfect. The study recommended combination of descriptive and explanatory research design to be used. Multiple regression model to be used to analyse the direct, mediating and moderating effect of business incubators and new venture creation. The reviewed studies focused on government business incubators and new venture creation. This study recommended a study on business incubators and new venture creation focusing on business incubators in universities in Kenya.

Energy is an important accessory for the development and sustainable growth. Changes in climatic conditions is arguably the biggest challenge the environment is facing around the world today. Climate Change has resulted in a the rise in temperatures globally. Making use of quantitative cum descriptive analytical methods, this research intends to address climate change using renewable energy. This will be done in a way that will also held deal with issues that might arise from the substitution of Fossil Fuel with Renewable Energy. A sample of 240 students in secondary schools in Nigeria and 205 University students in Northern Cyprus was used used in the data gathering process for this research. Findings, revealed that 82% of Nigerian international university students are cognizant of the fundamentals of climate change and how it affects the nation’s economy. In addition it was also noted countries with crude oil as their sole source of foreign exchange would be impacted by the switch from fossil fuels to renewable energy. Therefore, the research work implies that internalized knowledge of climate change and mounting anxiety result in a personal tipping point that prompts action.
