Published: October 2021

Solid oxides are the most used catalyst for the synthesis of biodiesel, one of which is calcium oxide (CaO). This research reports the synthesis of CaO catalysts sourced from chicken eggshells through the calcination process. Chicken eggshells were cleaned and dried for 24 h at 120 oC. The eggshells were then calcined at temperatures varying from 600 oC to 900 oC for 6 h and the resulted sample were characterized by FTIR and XRD. The biodiesel synthesis was conducted at 65 ºC with a reaction time of 2 h and the concentration of catalyst was varied at 3 wt%, 6 wt%, and 9 wt%. The optimal biodiesel synthesis was obtained at a concentration of CaO catalyst formed at a calcination temperature of 900 ºC at 9 wt%. The yield of biodiesel conversion was obtained at 81.43 % and glycerol was produced as a by-product.
The impact of the pandemic on moral panics in society
Authors: Tolmacheva Svetlana , Tkachev Alexander , Shamshin Maxim
Published: October 2021

The relevance of studying the impact of a pandemic on society is determined not only by medical problems, but also by social. The main purpose of the paper is to study the consequences of the pandemic in modern society with its information, cognitive-innovative, and hyperreal security. The article examines the phenomenon of the pandemic, its impact as a global threat and danger in micro-, meso-, and macrosocial structures and organizations, in state and international institutions. The pandemic becomes both a process of social freezing in the broadest sense (in the sense of any connection between people), and in the social, political, economic, and cultural context. The purpose of the study is to identify the most important factors affecting the psychological and somatic health of a person in the conditions of COVID-19. The paper presents a review of Russian and foreign studies of the psychological impact of the epidemic. The problem of the social impact of the pandemic as a global and massive threat to human relations in the information and digital world is a new phenomenon in the sociocultural space, as fear multiplies and repeats, and panic is intensified by simulations and fantasies, sometimes even more than real processes.
TÜRKİYE’DE SOĞAN VE PATATESTE EKİM ALANI - FİYAT ARASINDAKİ NEDENSELLİK İLİŞKİSİ: HATEMİ- J ANALİZİ
Authors: HURMA Gökhan , TÜZÜN RAD Sevgi
Published: October 2021

Tarım ürünleri içerisinde soğan ve patates, Türkiye’de üretim ve fiyat açısından şiddetli dalgalanma gösteren ürünlerdir. Bu durum üretici gelirini doğrudan etkilemektedir. Diğer yandan da; bu iki ürün, ortalama bir hane halkının temel tüketim malı olup, bunların fiyatındaki dalgalanmalar özellikle düşük gelirli hanelerin tüketim harcamalarını etkilemektedir. Bu bağlamda; soğan ve patatesin fiyat-ekim alanı-üretim miktarı arasındaki ilişkilerin belirlenmesi çok önemlidir. Bu çalışmada da; Türkiye’de soğan ve patatesin ayrı ayrı ve çapraz olarak ekiliş– fiyat ilişkisi ortaya konulması amaçlanmıştır. Bu amaçla çalışmada 1985-2018 yıllar arası incelenmiş ve Hatemi- J Nedensellik Analizi yapılmıştır. Çalışmada, soğan ve patateste ekim alanı ile fiyatın karşılıklı olarak birbiri üzerinde etkili olduğu saptanmıştır. Soğan ve patates arasında çapraz ilişki incelendiğinde de; soğanın ekim alanı ve fiyatındaki değişmenin, patates ekim alanı ve fiyatı üzerinde etkisi olduğu tespit edilmiştir.
İKİZ AÇIKLAR HİPOTEZİNİN AMPİRİK BİR ANALİZİ: TÜRKİYE ÖRNEĞİ
Authors: TUĞRAL Barbaros
Published: October 2021

Çalışmanın amacı; literatürde de önemli tartışmalara neden olan cari işlemlerdeki açıklar ile bütçe açıkları arasındaki ilişkiyi, 1985-2017 yılları arasındaki veriler kullanılarak, Ricardocu Denklik Hipotezi ve Geleneksel Yaklaşım açısından incelenmiştir. Aynı zamanda bu ilişki, Türkiye ekonomisinde de uygulandığı için, bu çalışmada ‘’Türkiye ekonomisindeki bütçe açıkları, cari işlemlerdeki açıkların nedenidir’’ hipotezi ortaya konulmuştur. Cari işlemlerdeki açıklar ile bütçe açıkları arasında elde edilen ilişki, Granger nedensellik testi ile ampirik olarak test edilmeye çalışılmıştır.
Kamusal alanda yapılan harcamaların, gelirleri aşması durumunda ortaya çıkan fazlalıklar ‘’bütçe açığı’’ olarak ifade edilmektedir. Özellikle gelişmekte olan ülkelerin gelirlerinin önemli bölümün vergiler olduğu ifade edilmektedir. Bu nedenle devlet, gelir vergilerini toplayamadığı zaman meydana gelen açıkları azaltabilmek için, dolaylı vergiler üzerinde yoğunlaşmakta ya da borçlanma yoluna gitmektedir. Ekonomi alanındaki dalgalanmalar, bütçe açıklarının oluşmasına neden olan en büyük etken olmakta ve bütçe açıkları da hem gelişmiş hem de gelişmekte olan ülkelerin ekonomilerini olumsuz yönde etkilemektedir. Kamu gelirleri ve harcamalarının paralel arttırılmaması, kaynakların yetersiz olması gibi nedenlerden dolayı bütçe açıklarının hacmi de genişleme göstermektedir.
Sonuç olarak, bu açıkların azaltılması veya ortadan kaldırılması için, ülkelerin makro ekonomik hedefler oluşturmaları gerekmektedir. Çünkü cari işlem açıkları hem gelişmiş hem de gelişmekte olan ülkelerin önünde önemli bir sorun olarak görülmektedir. Dolaysıyla çalışma sonucunda, Türkiye’de meydana gelen ikiz açıkların birbirleriyle ilişkili olduğu ortaya çıkmıştır.

A su vez, se reflexiona que la riqueza cultural gastronómica no se asocia solamente al sabor u olor de los platos, sino a la experiencia del gusto, a la interacción, intercambio cultural y de diálogo de los asistentes de la mesa de comida y a la conservación de su conocimiento empírico, como costumbres, tradiciones ancestrales y su patrimonio inmaterial.
Recovering What was Stolen by Embracing the Process of Rebuilding
Authors: Lee Elizabeth A.
Published: October 2021

This essay recounts a journey of one woman in higher education responding to and coping with the COVID-19 pandemic. The journey for all women in STEM is diverse, yet likely one common thread is a high standard for competence. Our ability to feel confident in our competence is threatened by the isolation and disruption brought on by the pandemic. The hope is that by sharing this personal narrative, the reader may be inspired to rebuild the areas of life needing attention. Self-care is time well spent, if for no other reason than to be able to regain what was lost. The ultimate goal is to rebuild back to a point of being resilient enough to serve as advocates for ourselves and others. By serving as confident advocates, women are well positioned to provoke the changes needed in order for institutions to effectively persevere during times of crisis.

El presente trabajo tiene por objetivo traer a la mesa de discusión aspectos de la sexualidad en las personas de mayor edad, teniendo por idea central la quiebra de paradigmas sociales y científicos inclusive. Se intenta explicar la idea errónea respeto de la incapacidad sexual de los ancianos, considerándolos seres asexuados, teniendo en cuenta apenas aspectos físicos, sin considerar el entorno, su vida sexual previa, y su integridad psíquica. Además, se abordarán aspectos fisiológicos naturales del adulto mayor, aspectos psicosociales y educación sexual en la tercera edad, con el objetivo de aclarar que la vejez no es en sí una patología, sino que es una parte esencial de la vida, construida con materiales acumulados en las etapas anteriores de la vida. En este contexto, el trabajo propone la presentación del tema por medio de búsqueda bibliográfica, cumpliendo los padrones exigidos.

Veganism and Feminism on Social Media Today
Authors: Jin Jean
Published: October 2021

While not new, veganism has gained popularity via social media. In particular, certain individuals and social groups on social media seem to play an especially important role in the spreading information about veganism and encouraging acceptance of the lifestyle. Additionally, feminism is another key concern among those key individuals. In this paper, I investigate the correlation between veganism and feminism on social media. I find that while veganism and feminism are both popular, they are accepted as lifestyles, rather than for ideological reasons.
Delay Time Parameter and Its Confidence Interval of Predictive Time Series of COVID-19 Outbreak Between the First and the Second Wave
Authors: Sunthornwat Rapin , Sookkhee Sirikanlaya
Published: October 2021

The outbreak of coronavirus disease 2019 (COVID-19) has become a major problem facing humans all around the world. For governments, in order to deal with the outbreak and protect the population, it is important to predict the number of infectious cases in the future to monitor the COVID-19 situation. This research aimed to compare the effectiveness of the logistic and the delay logistic time series in predicting the total number of infectious cases by using actual data from four countries, i.e. Thailand, South Korea, Egypt, and Nigeria. The total number of COVID-19 cases was collected during the first and the second wave of the COVID-19 outbreak. The validation and accuracy of the predictive growth curve time series were determined based on statistical values, i.e. the coefficient of determination and the root mean squared percentage error. It was found that the logistic time series was more appropriate for predicting the first wave in the four countries. For the second wave, the delay logistic time series was preferable. Moreover, the confidence interval based on Chebyshev’s inequality of delay time between the first and the second wave of the COVID-19 outbreak is also proposed.
An Infinite Game
Authors: Gessie Dean ,   After Dinner Conversation
Published: October 2021

What aspects of game theory and value theory get tossed out the window for pragmatism when your life is actually on the line? In this work of philosophical short fiction, the narrator is held by a mad man interested in delighting his grotesque ideas with a simple game. He has lined up four prisoners, front to back, selected for position by lottery, and intends to see how far his bayonet saw blade will penetrate. The first man in lines knows he will die, so he turns, runs, and is shot dead. Now the second man in line knows he will die. Our narrator tries to encourage the new front man to die with honor, rather than run away. Of course, his real motivation is to save his own life. While the narrator is talking to the man at the front of the line, their captor stabs the person in the back of the line, killing him. He has changed the rules, and now the game is over. "Everything" the mad man argues, "is a game." The only real question is, "can I play?"

What if the world simply changed around you? How would you know and accept the new reality? In this work of philosophical short fiction, Mary walks into her kitchen one morning and finds the sink has changed locations. It is literally, in a different part of the kitchen from where she remembers it the day before! Everyone else in her family says the new sink location is where it has always been. How on earth would you even move a sink overnight? There is nothing wrong with Mary. She has no mental disease. She correctly remembers the sink location the day before. It has simply moved, but she is the only one who knows it. In this new world she is also an artist and, it seems, has been a very good one for many years. What else could have changed? And how did the woman she was in her youth become the person she is discovering today?
Architecture design of a reinforcement environment for learning sign languages
Authors: Naranjo-Zeledón Luis , Chacón-Rivas Mario , Peral Jesús , Ferrández Antonio
Published: October 2021

Different fields such as linguistics, teaching, and computing have demonstrated special interest in the study of sign languages (SL). However, the processes of teaching and learning these languages turn complex since it is unusual to find people teaching these languages that are fluent in both SL and the native language of the students. The teachings from deaf individuals become unique. Nonetheless, it is important for the student to lean on supportive mechanisms while being in the process of learning an SL. Bidirectional communication between deaf and hearing people through SL is a hot topic to achieve a higher level of inclusion. However, all the processes that convey teaching and learning SL turn difficult and complex since it is unusual to find SL teachers that are fluent also in the native language of the students, making it harder to provide computer teaching tools for different SL. Moreover, the main aspects that a second language learner of an SL finds difficult are phonology, non-manual components, and the use of space (the latter two are specific to SL, not to spoken languages). This proposal appears to be the first of the kind to favor the Costa Rican Sign Language (LESCO, for its Spanish acronym), as well as any other SL. Our research focus stands on reinforcing the learning process of final-user hearing people through a modular architectural design of a learning environment, relying on the concept of phonological proximity within a graphical tool with a high degree of usability. The aim of incorporating phonological proximity is to assist individuals in learning signs with similar handshapes. This architecture separates the logic and processing aspects from those associated with the access and generation of data, which makes it portable to other SL in the future. The methodology used consisted of defining 26 phonological parameters (13 for each hand), thus characterizing each sign appropriately. Then, a similarity formula was applied to compare each pair of signs. With these pre-calculations, the tool displays each sign and its top ten most similar signs. A SUS usability test and an open qualitative question were applied, as well as a numerical evaluation to a group of learners, to validate the proposal. In order to reach our research aims, we have analyzed previous work on proposals for teaching tools meant for the student to practice SL, as well as previous work on the importance of phonological proximity in this teaching process. This previous work justifies the necessity of our proposal, whose benefits have been proved through the experimentation conducted by different users on the usability and usefulness of the tool. To meet these needs, homonymous words (signs with the same starting handshape) and paronyms (signs with highly similar handshape), have been included to explore their impact on learning. It allows the possibility to apply the same perspective of our existing line of research to other SL in the future.

Background

Secondary salinized soil in greenhouses often contains excess nitrate. Inoculation of Bacillus megaterium NCT-2 with nitrate assimilation ability represents an attractive approach for soil remediation. However, the effects of NCT-2 on the structure and function of soil microbial communities have not been explored.

Methods

Greenhouse experiments were carried out to investigate changes in soil properties, Brassica chinensis L. growth, bacterial, and fungal community structure and function in response to NCT-2 inoculation.

Results

The NCT-2 inoculant significantly reduced the nitrate content in B. chinensis and inhibited the rebound of soil nitrate in the later stage. The shifts of bacterial community structure and function by NCT-2 was negligible, and a greater disturbance of soil fungal community structure and function was observed, for example the strong inhibitory effect on ectomycorrhizal fungi. These results indicated that the NCT-2 inoculant likely achieved the remediation effect in secondary salinized soil by shifting fungal community. The present findings add to the current understanding of microbial interactions in response to bacterial inoculation and can be of great significance for the application of NCT-2 inoculants in secondary salinized soil remediation.

Pseudomonas aeruginosa is one of the most widespread gram-negative microorganisms identified in the clinical samples and most common causes of hospital acquired infection. P. aeruginosa is affecting both indoor and outdoor patients throughout the world. Due to frequent mutation in          P. aeruginosa highly resistant strain developed rapidly. The aim of the study to determine the prevalence of P. aeruginosa species in different samples isolated from a Tertiary care Hospital as well as determination their diverse antibiotic resistance pattern. This cross-sectional study was carried out to determine in-vitro resistance pattern of P. aeruginosa isolates to common antimicrobial agents by disc diffusion method. Various clinical samples were collected from Bangladesh Health Sciences Hospital (BIHS) General Hospital, Dhaka. This research was carried out in the Department of Microbiology of Bangladesh University of Health Sciences (BUHS). Isolation, identification and antibiogram were performed for P. aeruginosa following standard microbiological laboratory procedure. A total of 218 P. aeruginosa were isolated from 3062 different clinical specimens which are statistically significant (p<0.0001). Among the highest number of P. aeruginosa were isolated from outdoor patients 140 compare to Indoor patients which are significantly higher (p <0.013). In this study Male (68.3%) are more vulnerable to P. aeruginosa infection compare to females (31.7%) which is also statistically significant. Young people (less than 35 years) were more susceptible to P. aeruginosa infection which is also statistically significant (p< 0.01). The highest number of P. aeruginosa was isolated from wound (43.12%), followed by pus (40.33%), sputum (8.71%) urine (7.80%). The maximum number of P. aeruginosa in various samples was resistant to aztreonam and co-tromoxazole followed by cephalosporins, aminoglycosides, carbapenems. The most sensitive antibiotic was colistin of followed by gentamycin and tetracycline. To control the spread of resistant bacteria, it is disparagingly vital to have stringent antibiotic guidelines. The antibiotic susceptibility pattern of P. aeruginosa requires to be continuously monitored in specialized clinical units and the results readily made available to the clinicians to minimize the resistance.

Shelf life of custard apple is limited due to climacteric nature. In the present study, two application methods along with different concentration of hexanal formulations were used, first hexanal vapour at different concentrations (0.005, 0.01, 0.02, 0.05% v/v) and second hexanal dip (0.5, 1, 1.5, 2% v/v) along with control were evaluated on custard apple dipping fruits for 2 min and 4 min and store at ambient temperature (27±2ºC). Hexanal filter paper dip in 0.05% concentration effectively maintained the firmness, total sugar, reducing sugar, preserved L*, a*, b* value, extend shelf life and maximum BC ratio during storage from day 1 to days 14 as compare to control. Therefore, we concluded that hexanl vapour(0.05%) was effective to use post harvest technology for custard apple.
Determination and Removal of Phosphate and Nitrate from the Ground and Surface Water at the Three Counties of Guyana

Published: October 2021

Standard analytical procedures that are based on colourimetry facilitated the determination of PO43- and NO3- in the ground and surface waters from the three (3) counties of Guyana. Phosphates and nitrates beyond their permissible levels in natural waters can pose significant threats to the aquatic environment, its inhabitants, and the health of humans and terrestrial animals. For this reason, this study aims to investigate the use of metal (nickel, cadmium, cobalt) ferrocyanides (octahedral complexes that facilitate adsorption of anions primarily on its two divalent transitional metals) as adsorbents to facilitate the removal of the aforementioned anions. Results revealed that nickel ferrocyanide is the most effective adsorbent for treating ground and surface waters that contain high levels of PO43-, while it was also the most effective adsorbent for treating surface waters that contained NO3-. Fixed volumes of water samples were treated with 50 mg, 100 mg, and 150 mg of the adsorbent. The correlation coefficient computations revealed that they were instances of both positive and negative correlations, which implied that increasing adsorbent dosage resulted in increased adsorption and other instances decreased adsorption, respectively. This occurrence went against literature, possible reasons for this are explained in detail within the discussion portion of the manuscript. Adsorption isotherms and Langmuir plots were used to facilitate adsorption studies, in various instances, the generic appearance of these isotherms was not observed, possible reasons for this occurrence are also explained in more detail within the article. Based on observations within the article, the use of cobalt ferrocyanide for treating groundwater and removing PO43- is not recommended, while cadmium ferrocyanide is not recommended to be used to facilitate the removal of NO3-, due to the possible formation of Co3(PO4)2 and Cd(NO3)2, respectively, which consequently affected the results. Technologies like those studied in this research project should be explored and studied more in-depth (particularly with regards to the stability of the adsorbents) with regards to the treating of ground and surface water supplies, to facilitate the removal of PO43- and NO3-, since the results observed, though on a small scale, can be seen to move us closer towards a green and sustainable environment, inclusive of safeguarding the health of the Worlds’ people and expanding the scope of cost-effective and simple methods that aid in the removal of anions from natural waters.

Published: October 2021

Objective: The aim of this study was to explore dispersion of effect sizes regarding reported preterm births and to find out pooled prevalence estimate of preterm birth using meta-analysis.

Methods: For meta-analysis a total of 1106 published studies were initially found related to the preterm births, after careful screening 41methodologically sound studies were selected for meta analysis.

Results: In this study 41 published studies were taken with overall sample size of 6781976. Using meta-analysis the overall prevalence of preterm birth was found as 11.3% with significant erogenous results. Rosenthal method showed there exist significant publication bias in pre-term prevalence studies.

Conclusions: Based on meta-analysis results it can be evidently concluded that there exists enormous heterogeneity in pre-term prevalence reporting and the overall pooled prevalence is too high. The health care providers must focus on preventive measures and early screening of high-risk pregnancy.

Spirituality is a living and vital component of mankind in which people are looking for ultimate meaning, purpose, and mastery while engaging in connections with themselves, their family members, others, their communities, society, nature, and the divine or spiritual. Health, illness, beliefs, knowledge, and medical practices are all influenced by culture, and dentistry is no exception. Everyone, whether rural or urban, has its own health and illness beliefs and practices. The only way to provide culturally sensitive health care is to be aware of, listen to, and be attentive to each patient, as well as to inquire about personal needs and wishes when appropriate. Spiritual well- being is regarded as the fourth dimension of health. It helps people realize their greatest potential, find meaning and purpose in life, and find fulfillment from within. The individual's lifestyle may have a significant impact on his or her oral health behaviour. Caries and plaque-induced periodontal illnesses are linked to personal hygiene, food intake frequency, motivation to preserve oral health, and in certain circumstances, religious commitment Dental myths are widespread and unquestioned misleading ideas that often arise as a result of a lack of education, spiritual beliefs, and traditional factors based on non-scientific information. Despite global advances in diagnosis, treatment, and prevention, some people continue to hold on to their traditional values, practices, beliefs, and myths. If these myths are exposed in a timely manner, it may be possible to reduce the costs and time required for dental treatment, thereby converting an operative treatment into conservative dental management and improve patient satisfaction.

Background: Silver nanoparticles (AgNPs) have been used in various medicinal products because of its anti-microbial properties. This research study has reported a simplistic, cost effective and eco-friendly method for the synthesis of Silver nanoparticles.

Objective: The objective of present study was to compare the synthesis of silver nanoparticles (AgNPs) from various parts of Citrus maxima fruit like pulp, peel and seed.

Methodology: The synthesized nanoparticles were characterized by the use of UV-visible spectroscopy, fourier transform infrared spectroscopy and transmission electron microscopy. Time-dependent synthesis of AgNPs was studied spectrophotometrically. UV–visible spectrophotometer was used to confirm the synthesis of AgNPs which showed maximum absorption at 410 nm, 420 nm and 430 nm respectively.

Expected Results: Fresh peel extract exhibited the highest concentration of silver nanoparticles in comparison to pulp and seed. Fourier-transform infrared spectroscopy (FTIR) spectra analysis confirmed the presence of possible functional groups in AgNPs which can be responsible for reduction of nanoparticles. Morphological characters of AgNPs were analyzed using transmission electron microscopy (TEM) depicting the particles size as 12.58-47.80 nm. The antibacterial property of synthesized AgNPs was analyzed viz Escherichia coli (MTCC 1687) and Staphylococcus aureus (MTCC 902), specify them to be effective against both gram positive and gram negative bacteria.

Conclusion: These results suggested that the fresh peel extract of Citrus maxima is a high-quality bioreductant for the synthesis of silver nanoparticles and have prospective for various biomedical applications.
