Optimization of the demineralization process of black soldier fly (Hemertia illucens) pupa shell maggot chitosan and the physicochemical characteristics
Authors: Mira Maulidina  , Muhammad Rifqi  , Siswanto
Published: November 2024

Chitosan is a derivative compound of chitin that has undergone deacetylation. Chitosan has three stages of the manufacturing process, including demineralization, deproteinization, and deacetylation. Chitin is also found in the black soldier fly maggot pupae, but maggot pupae contain high minerals content that can affect the purity of the resulting chitosan. Therefore, demineralization treatment is necessary to remove minerals from maggot pupae shells. This study aims to optimize the demineralization process by finding the best type of acid solvent, the best incubation time, and combination treatments. The black soldier fly (BSF) maggot pupa shell was soaked using various formic acid, hydrochloric acid, and nitric acid solutions with incubation times of 60, 120, and    180 minutes. Chitosan characterization was carried out following SNI 7949:2022, including water content, ash content, nitrogen content, pH, deacetylation degree, characterization of functional groups with FT-IR, and as an antimicrobial comparison is formalin. The best demineralization treatment was obtained at 0.5 M nitric acid treatment with an incubation time of   120 minutes. The characterization of chitosan produced 7.81% water content, 0.56% ash content, 4.73% nitrogen content, pH 7.39, and 75.14% deacetylation degree. Characterization of groups on chitosan with FT-IR resulted in the absorption of O-H and N-H groups 3484 cm-1 and 3152 cm-1; C-H 2877 cm-1; and C=O 1653 cm-1. The inhibitory power against E. coli of the BSF maggot pupa shells chitosan is better compared to chitosan standard but not better than formalin.

Genome editing through cisgenesis develops into scientific breakthroughs in accelerating oil palm breeding programs. However, one remaining problem is the low success of transformed-calli regeneration, while its scientific explanation is still underexplored. This study aimed to characterize and regenerate transformed-calli using various amino acids and antioxidants.  Transformed callus that did not regenerate (un-regenerated transformed callus or UTC) after the transformation process was taken, then T-DNA integration was detected using the NPTII gene. Furthermore, the UTC was divided into four types based on morphological characteristics. The four types of UTCs were regenerated on media enriched with glutamine (for Type-1 callus), cysteine and putrescine (for Type-2 callus), and a combination of cysteine and ascorbic acid (for Type-3 and Type-4 callus). The research results obtained NPTII successfully amplified with a band size of 700bp. The results showed that on Type-1 callus, enrichment media with 10 mg L-1 L-glutamine could induce the formation of new nodular structures on UTC Type-1. On Type-2, media enriched with 5 mg L-1 L-cysteine + 20 mg L-1 putrescine increased the density of callus structures. Media enriched with 25 mg L-1 ascorbic acid + 25 mg L-1 L-cysteine could prevent the spread of brown callus on Type-3 callus, while Type-4 callus did not show any response and became dry. Our new findings will facilitate the basic research and unregenerated transformed callus and morphological callus development behavior in oil palm.
Application of lactic acid bacteria to improve the food safety of sago starch
Authors: Amalia Tryanisa Ridla , Sunarti Titi Candra , Meryandini Anja
Published: November 2024

Sago starch production in local industries is still carried out traditionally and uses poor-quality water. This production causes sago starch to be fermented spontaneously, resulting in sour sago and possibly contamination by pathogenic bacteria. Lactic acid bacteria (LAB) can produce lactic acid and are suitable for use as a starter. Adding LAB as a starter in sago starch fermentation is expected to reduce the number of pathogenic bacterial growths, thereby increasing food safety in sago starch. This research aimed to obtain LAB and evaluate their use in sago starch fermentation to improve food safety. LAB selection was conducted by testing the LAB tolerance ability to low pH and the adaptability of the LAB growth in sago starch. This study was carried out using and without a LAB liquid starter. The water source during the fermentation originated from drinking water and the sago starch industrial factory. The fermentation was carried out for ten days at room temperature with an observation every two days. The results showed that fermented sago starch using drinking water did not harbor E. coli, Salmonella, or Shigella bacterial contamination. In contrast, sago starch fermented using water from the factory harbored these bacterial contaminations. Adding LAB IL1 isolate as a starter in fermentation showed the ability to reduce the number of pathogenic bacteria in sago starch.

Published: November 2024

Basal stem rot disease caused by Ganoderma is a major problem in palm cultivation in Indonesia, so an appropriate solution is needed to overcome this problem. One of the solutions that can be applied is through silver nanoparticles. Synthesis of silver nanoparticles can use coconut leaves as a source of flavonoids. Flavonoids are one of the phenolic compounds that are widely used in the process of synthesizing silver nanoparticles. Flavonoid compounds have a hydroxyl group (OH), which can be reduced by donating electrons to the Ag+ ion from AgNO3 to Ag0. This research aims to synthesize silver nanoparticles (AgNPs) using coconut leaf water extract and its assessment as an antifungal for Ganoderma boninense. Silver nanoparticles were synthesized by mixing coconut leaf extract in 1 mM of AgNO3 solution with a ratio of 1:9 (v/v). The concentrations of coconut leaf water extract were 1% and 3% with a heating temperature of 60°C. Silver nanoparticles were characterized using a UV-Vis spectrophotometer, PSA, FTIR, TEM, and SEM-EDS. The AgNPs had a maximum wavelength of 430 nm, with morphologies like a ball, triangle, and square, a mass percentage of Ag of 51.77%, smallest particle size of 63.29 nm, PdI value of 0.3361, and a zeta potential of -16.98 mV. The FTIR spectra show that the functional group that plays a role in the reduction process is the –OH group. The antifungal activity assay produced the highest percentage of colony growth inhibition (68.37%) at a concentration of 4.9 ppm in the 10-day incubation.

Published: November 2024

The Zambli variety of date palm shows potential for cultivation in tropical regions, as its fruits are edible during the Rutab stage. However, large-scale production of Zambli seedlings presents a significant challenge. In vitro propagation offers a solution for producing large quantities of clonal planting material. This study focuses on inducing callus formation from the four-layered shoot tips of young leaves and regenerating these calli into plantlets through somatic embryogenesis. Explants were cultured on a modified MS medium with 10, 50, or 100 mg L-1 2,4-dichlorophenoxyacetic acid (2,4-D), combined with 1 or 3 mg L-1 N6-(2-isopentenyl)adenine (2-iP). Embryo maturation was performed on the same medium without 2,4-D, while a hormone-free medium was used for plantlet regeneration. The results indicated that the highest callus induction occurred from the younger leaf layer (layer 1) in the medium containing 100 mg L-1 2,4-D and 1 mg L-1 2-iP, achieving a callus formation rate of 82.3%. Successful callus induction was achieved from the first, second, and third layers of young leaves. Somatic embryo maturation and plantlet regeneration were also completed, producing vigorous, well-rooted plantlets. Additionally, the development of date palm cv. Zambli in vitro culture through somatic embryogenesis was confirmed through histological analysis.

Published: November 2024

Exploration of natural resources, particularly fossil fuels, is necessary given the sharp rise in energy demand across a wide range of industries. The risk of unpredictable fuel costs, rising pollution, and climate change is elevated as a result of that specific event. In order to address the problem of danger originating from present conventional fuel, it is crucial to use renewable energy that is regarded as sustainable and safe. In the future, bio-hydrocarbons are one energy source that is expected to be used as fuel. In both biological and non-biological processes, biohydrocarbons—hydrocarbons originating from biomass—can be created. Employing the Chlorella variabilis Fatty Acid Photodecarboxylase (CvFAP) enzyme from E. coli recombinant is a remarkable recent technique for producing bio-hydrocarbons. This enzyme has the ability to change free fatty acids, according to extensive studies when induced by blue light and accompanied by the addition of substrates. This study has confirmed the success of producing bio-hydrocarbons in the form of pentadecane with a selectivity of 16.44%. This experiment also indicated that several substantial components are needed in the bio-hydrocarbon synthesis process to obtain an optimal result. The components are the use of TB growth media, the selection of a protein concentration of 1777.5 l ppm, activation time for 3 hours, and the preference for substrate type in the form of 50% CPO.

A Child with a Parent Serving a Prison Sentence and its Impact on the School Environment
Authors: Culenova M. , Mackinova M. , Olah M.
Published: November 2024

The school environment is where a child spends the second
most amount of time (after the family environment). Leskova (2018, p. 52) claims that “the school and the school
environment also play an irreplaceable role in the formation of a child.” Professional authors are largely inclined to
claim that having a parent in VTOS has a negative impact on
a child’s school results. „The stress caused by a parent being
in prison or in VTOS can affect a child’s school performance.
Strong emotions and the actions associated with them can result in problems in the classroom and social isolation“ (Children of Incarcerated Parents Toolkit, 2022, p. 6). This problem
is then the subject of social work, and as Planka et al. (2024,
p. 1) state, we use the means of social policy in the school
system, which leads “by providing for the social needs of the
population and creating conditions for improving the living
conditions of individuals and groups.” Having a parent VTOS
can affect the child in several areas:
l Mental health. The child loses physical contact with the
parent, which can be reflected on the psychological side of
the individual. Children may experience different feelings
such as guilt and sadness. As a result, mental problems in the
form of depression and anxiety are created.
l Social relations. These relationships can be influenced by
the family environment as well as the school environment.
In the family environment, the whole family suffers and the
child can sense instability in the home environment. Discrimination and ridicule from classmates can occur at school
l School achievements. The previous two areas can affect the
school area. The family situation can lead to absence from
school or failure to fulfill school duties.
According to Slavin (2000, In: Mcmahon, 2002, p. 5 ), “children with incarcerated parents are at increased risk of poor
school performance, dropping out of school, gang involvement, early pregnancy and drug abuse.” In some cases, the
departure of a parent to VTOS can have the opposite, i.e., positive effect on the child. Some children, as well as families,
are relieved after the departure of a parent or family member
to VTOS. However, as Planka and colleagues (2024, p. 119)
point out, whether the situation has improved or deteriorated
after the parent’s departure, there must always be communication between the child, the family and the parent in VTOS.
“Communication as a process of mutual understanding plays
a huge role in all aspects of life - private life, the work environment and interpersonal relationships.” Matejkowski, Johnson and Severson (2014, [cit. 2024-05-22]) add that this fact
can also leave children with clinical problems, such as depression and anxiety, problems with attention, disruptive behavior,
poor results at school, disruption at home and a reduced likelihood of dealing with anxiety and stress in the future.

Published: November 2024

The article examines social services and their impact on the
citizens of the Czech Republic. This is not only important
from the point of view of the present time, but also for the
acute needs of the localized places of the studied area. The
main objective of the study was based on this aspect in line
with the main research question: How important is the concept
of social services in the networking of religious institutions in
the Czech Republic? The quantitative representative sample (online) consisted of 858 respondents from the Czech Republic, of which 59% (N = 506) were women and 41% (N = 352)
were men. Age group representation was balanced across the
five main categories, with the 41-59 age group dominating at
41% (N = 351). Two-thirds of respondents 67% (N = 575)
reported having a college or high school education. The research sample identified 54% (N = 465) of participants who
identified themselves as atheists in terms of religious beliefs.
Almost half of the 48% (N = 413) surveyed identified having
the Ústí nad Labem region as their place of residence, which
can be considered a positive given the current social issues in
the North Bohemian territory. In turn, we see a balanced view
of our respondents in the five marked groups in relation to the
size of the place of residence. From the research results, we
can conclude that the social sphere plays an important role
in the Czech Republic, where we see a significant role in the
connection of religious institutions. It is from these religious
places that our respondents expect the greatest amount of „social attention“.

Authors: Benedek Jakubcova D. , Kralova Z. , Oumo B. , Ontita J.
Published: November 2024

Objective: To identify gender differences in behavioural factors and treatment related factors of ARV therapy as a predictor to treatment adherence.
Design: Cross-sectional study.
Methods: A quantitative study using a standardized PLWHA
questionnaire was conducted in the Kibera informal settlement in the capital, Nairobi, Kenya. Data were collected by
community health volunteers during home visits in cooperation with ART health facilities.
Results: The observed sample consisted of a total of 272
persons living with HIV/AIDS in the Kibera informal settlements, of which 64.3% were women and 35.7% were men. We
found a significantly higher rate of the behavioural risk factors
cigarette smoking and alcohol drinking in men compared to
women. There was no significant difference in the factors of
patients’ medical history between men and women. A significant difference was found in the source of ARV treatment
therapy, travelling costs to ARV treatment facilities, loss of income due to visiting an ARV treatment facility and extra costs
related to ARV treatment between the men and women in our
study group. Another significant difference was observed in
disclosure related factors - the HIV status of the current sexual
partner, and the current sexual partner being on ARV therapy
and disclosing this information to the current sexual partner.
Conclusion: Alcohol drinking and smoking cigarettes were
the most common behavioural risk factors and were more
prevalent in men. Women significantly dominated in treatment
related factors of ARV therapy.
Narcissistic Privacy as a Barrier to Socialization
Authors: Kralik R. , Mahrik T. , Spuchliak J. , Maturkanic P. , Pavlikova M.
Published: November 2024

A democratic society is characterised by tensions between private and public interests. At different stages of a society’s development, the emphasis shifts to one side or the other within the dialectic of both aspects of the functioning of society.
We believe that the degree of disharmony between the two
can result in problems and phenomena that ultimately pose
a serious threat to the functionality of society as a complex
whole. This study focuses on the phenomenon of privacy in
relation to human socialization in a changing open society.
We are convinced that in the last decade and especially in the
post-pandemic period we are experiencing an unhealthy assertion of private interests that stem from the narcissistic mental
world-setting of contemporary man. We seek to highlight the
causation and manifestations of a narcissistic culture, part of which is a lifestyle of dominance of privacy curved in on itself, and the implications associated with it – especially in the
realm of social interest and interpersonal socialization.
Self-evaluation and Self-esteem in Children with Type 1 Diabetes Mellitus
Authors: Libova L. , Debnarova J. , Bachrata Z. , Musinska J. , Nagyová I. , Minarik P.
Published: November 2024

Background: Diabetes mellitus (DM) is the most common
childhood endocrine disease. Treatment of the disease is complex and includes lifestyle modification, self-monitoring, insulin administration and regular physical activity. After starting
school, children gradually become aware of their differences
from their peers, which together with other factors can affect
their self-evaluation. Hence, in the present study we focused
on the influence of self-evaluation on the degree of compensation in children with type 1 DM.Methods: The sample consisted of 64 parents of 6-12-yearold children that are regularly treated in the Diabetology Outpatient Clinic of the Children’s Diabetes Centre. To obtain the
data, a self-assessment questionnaire was used. To verify the
hypotheses, statistical methods were used: the chi-square test
(verifying the relationship between nominal data and verifying the differences between the compared groups), the Student’s t-test (a comparison of mean values), and the F-test
(a comparison of variances).
Results: The relationship between children’s difficulties at
school and the occurrence of acute complications was found
in the sample of this study. The relationship between difficulties at school and the frequency of hospitalisations of children
with type 1 DM was confirmed.
Conclusions: The present study suggests there is a relationship between difficulties of children with DM in the school
environment and the occurrence of acute complications or
hospitalisations of children with DM. Thus, nursing interventions should be aimed at improving self-esteem to achieve the
desired compensation of DM.
An investigation into the Role of early Marriage in developing suicidal Ideation among Girls in Dir, Khyber Pakhtunkhwa, Pakistan
Authors: Khan N. , Ali I. , Ahmed Z. , Hussain S. , Rasool F.
Published: November 2024

Early marriage is a common practice in African and Asian regions, including Pakistan. For females, early marriages have
numerous adverse consequences, including those that are
mental, physical, social and educational. However, so far, the
association between early marriages and suicidal ideation and
behaviours haven’t been well researched. Therefore, this study
aims to explore the relationship between suicidality and early
marriage. This study was conducted in Chakdara and Ouch
region, Khyber Pakhtunkhwa, Pakistan. This study is framed
under a mix-method research design and is cross-sectional.
Sampling for the study was done in multiple phases. First, girls were identified who were married before 18 years of age,
and second, there was an identification of girls who were not
happy in marital life. A total of 120 girls were identified as
a target population, and 92 were sampled through the Uma
Sekaran sample size table. Third, 2 completed suicides and
4 uncompleted suicide attempts were identified, comprising
a total of 6 cases among girls. An SIQ questionnaire devised
by William M. Reynolds was utilized for judging suicidal ideation among the 92 sampled girls. Informal interviews were
carried out for the 6 cases of completed and uncompleted suicides from key informants (family members and nearby people). The information collected was analysed quantitatively
(data collected through the SIQ questionnaire), descriptive
and inferential statistics were used, and data collected through
informal interviews was transcribed and narrated. Findings
show that suicidal ideation prevails among girls that are married before 18 years of age, and in some cases, it leads to suicide attempts. The most notable causes of suicidal ideation
and suicide attempts among girls married early include stress
due to an inability to take care of the husband and his family
in the expected way, the burden of household responsibilities,
relationship issues with the husband and/or his family, mental
changes with pregnancy and rejection by parents.
Homelessness and suicidality: How do new emigrants confront the dilemma? Evidence from existing research conducted in Canada

Published: November 2024

Framed under a systematic review design, this study aimed to
extract specific evidence of how homelessness is associated
with suicidality among new emigrants to Canada. A database
search strategy was adopted, and biasness in the selection
of studies was avoided by consulting with two independent
reviewers. 18 studies were sampled purposively. It was concluded that migration to Canada is an important component of
Canadian society. However, like other social processes, there
are certain cons of migration to Canada. The newly emigrated
individuals confront economic vulnerability, and homelessness is one of the possible outcomes. Homelessness is directly
and indirectly associated with suicidality.
Refugee Crisis in the European Union Countries: Problems and Consequences

Published: November 2024

The article presents the results of a study of the negative impact of the European migration crisis (European refugee crisis) on various spheres of European society and the societies
of individual EU countries (using the examples of Germany
and Poland). The research methodology involves identifying
current problems of Ukrainian migrants, assessing the socioeconomic situation of EU citizens, assessing the impact of
the migration crisis and identifying mechanisms for reducing
its negative impact using sociological and expert survey methods. A comparative analysis of the features of the European
migration crisis of 20152016 and the crisis caused by the war
in Ukraine in 2022 was carried out. The main negative consequences of the migration crisis for Europe are identified as:
a gradual decline in the economy and inflationary processes,
rising prices and housing rents, and overloading of the social security system, social services, healthcare and the labor market. It is noted that, on one hand, the sociocultural proximity
and similarity of democratic, humanistic values Ukrainians
and Europeans share contribute to the integration of Ukrainian
refugees in host countries. On the other hand, the positive attitude of national governments and citizens towards Ukrainian
refugees can strengthen the process of intolerance towards
other refugees of culturally different countries, therefore acting as a factor of internal political and inter-ethnic conflicts.
The following mechanisms have been identified to reduce the
level of the negative impact of the migration crisis on the EU:
economic (redistribution of the EU budget in accordance with
the number of refugees in the host country, investing in the
restoration of Ukraine after the war); international legal (improving international legislation regarding refugees); political
(updating and developing a strategy for the EU migration policy); social mechanisms aimed at social support for refugees.

Published: November 2024

Occupational health and safety have become essential pillars in the modern workplace, reflecting the growing emphasis on valuing employees within their work environments. As Turkey has seen a rise in occupational accidents and diseases, new legal regulations have become necessary. The goal of these regulations extends beyond merely preventing accidents and illnesses; they also aim to foster mental well-being through a safe working environment. A particular area of concern is the radiation risk in the healthcare sector. This study explores the potential hazards and risks faced by healthcare workers who are exposed to radiation by reviewing existing literature. It assesses the devices used by radiology department staff and their associated exposurelevels. Furthermore, the study proposes strategies to enhance risk awareness amongthese workers and to mitigate potential dangers.
Judicial Preclusion in International Arbitration: Comparative Analysis of UK, Australia, and Malaysia’s Practices
Authors: Che Rosli Iyllyana , Ghouri Ahmad , Ghapa Norhasliza , Zakariah Asril Amirul , Kamariah Musa Murshamsul
Published: November 2024

This paper examines the issue of judicial preclusion in international arbitration, focusing on whether an award-debtor’s failure to challenge a foreign award at the supervisory court precludes them from contesting the enforcement of an award in another jurisdiction. Through a comparative analysis of judicial practices in the United Kingdom, Australia, and Malaysia, the study evaluates the extent of harmonisation in the application of Article V of the Convention on the Recognition and Enforcement of Foreign Arbitral Awards 1958 (NYC 1958). The findings reveal divergences: while UK and Australian courts adopt a flexible approach, allowing enforcement-stage challenges irrespective of prior actions at the supervisory court, Malaysian courts demonstrate a strong pro-enforcement bias, often deferring to the decisions of the supervisory court and restricting opportunities for re-litigation. This paper engages with the theories of res judicata and finality, exploring their interplay with judicial discretion and highlighting the tension between fairness and the finality of arbitration awards. It concludes with critical recommendations for enhancing harmonisation under the NYC 1958, including clearer guidelines on judicial preclusion, the integration of international best practices, and reforms to balance enforcement predictability and certainty in international arbitration

Este trabalho apresenta a determinação das concentrações de Rn no ambiente de minas subterrâneas, visando ao estabelecimento de correlações entre as concentrações e as características geológicas das minas subterrâneas de fluorita e de carvão do Estado de Santa Catarina. Para a determinação da concentração de Rn, foram utilizados detectores de traços nucleares (Carbonato Diglicol Alílico CR-39). Foram instalados detectores passivos de Rn em locais de maior circulação de pessoas, tais como galerias, corredores de acesso, salas de reunião, almoxarifados, oficinas e shafts. As análises quali-quantitativas de radioatividade das rochas foram realizadas um sistema de espectrometria gama. Os resultados mostram que as minas de carvão apresentam baixos valores de concentração de Rn no ar (< 500 Bq/m3) e não requerem ações protetoras. Isto pode ser explicado pelo fato que o U não tem associação geoquímica direta com o carvão. As baixas concentrações de Ra nas rochas (arenitos e siltitos na capa e na lapa) e no carvão ratificam essa hipótese. Além disso, a eficiência da ventilação normalmente requerida em função da presença de metano, gás combustível, contribui para a redução das concentrações eventuais de Rn no ambiente mineiro. As concentrações de Ra-226 das rochas que compõe a capa e a lapa, bem como do carvão, não apresentam correlação alguma com a concentração de Rn no ar. Essa falta de correlação é esperada porque não se consegue atingir o equilíbrio secular no interior da mina, pois o eficiente sistema de ventilação retira do ambiente mineiro o Rn exalado das rochas. As minas RB e NF, de fluorita, apresentam elevadas concentrações de Rn no ar, acima do intervalo de níveis de ação preconizado pela Agência Internacional de Energia Atômica. Já a mina MF, de fluorita, apresenta valores da concentração de Rn-222 no ar entre 500 e 1500 Bq/m3. As concentrações de Ra-226 do granito normal, da fluorita verde e da fluorita roxa não apresentam correlação alguma com os valores das concentrações de Rn-222 no ar. Porém, a concentração de Ra-226 do granito alterado apresenta tendência a uma correlação positiva com a concentração de Rn no ar. No interior da mina, o granito alterado contribui de forma mais significativa para o aumento da concentração de Rn-222 no ar, quando comparado ao granito normal e à fluorita. Essa maior contribuição pode ser explicada pela alteração intempérica do granito, como fraturas e poros abertos, além da alteração de minerais primários, facilitando, assim, a exalação do Rn do granito alterado.
A formação intelectual, moral e física: educar para a vida completa e a emergência do capitalismo
Authors: Morais Cleidiane
Published: November 2024

O presente trabalho busca investigar, no recorte temporal do Brasil Império das últimas décadas do século XIX, as disputas e tensões no cenário político e educacional do Ceará e da Corte, em torno da implementação do princípio do “ensino integral” no currículo da Instrução Pública Primária. Tendo como fontes os escritos de importantes figuras do movimento político e letrado à época – mais especificamente, o artigo de Francisca Clotilde intitulado “A educação moral das crianças na escola”, veiculado em Fortaleza, na revista A Quinzena, em 1887; o relatório de estudos de Amaro Cavalcanti publicado no jornal Cearense, em 1881; e o parecer de Rui Barbosa sobre a reforma do Ensino Primário, de 1883 – nos debruçaremos sobre a dinâmica conflitual que envolveu as discussões que tomaram como pauta a renovação do currículo escolar primário e dos métodos de ensino ensino que melhor atenderiam as exigências da “vida ativa” e do exercício do trabalho, no contexto de emergência do capitalismo.
Racismo científico e branqueamento no Brasil Republicano (1889-1930)
Authors: Santos Filho Adao Ferreira dos , Silva Cássio Roberto Borges da
Published: November 2024

O objetivo deste artigo é discutir – com base em procedimentos de revisão bibliográfica e análise comparativa – algumas variantes das teorias raciais que concorreram no Brasil, em fins do Império e durante a Primeira República, para explicar a composição sociorracial do país e, que mais do isso, objetivaram validar a posição de subalternidade da qual a população africana e afro-brasileira, recém-saída do cativeiro, já era alvo. Destarte, analisamos o contexto brasileiro pós-Proclamação da República, bem como discutimos as principais teorias racistas que circularam no Brasil, filiadas, num primeiro momento, às noções de monogenia e poligenia, com o fito de relatar de que forma elas foram utilizadas para implementar um projeto político e econômico que, a nosso ver, tinha por pano de fundo um projeto de obliteração da presença negra africana na cultura brasileira. Para tanto, analisamos as contribuições de autores como Michel Foucault (2010), Lília Schwarcz (1993), Sílvio de Almeida (2020), George Reid Andrews (2014).

The role and techniques of green accounting in sustainable business practice
Authors:   Latvia University of Life Sciences and Technologies, Oborska Anna
Published: November 2024

By highlighting the importance of green accounting techniques in encouraging sustainable business practices, this research delves into their evolution, definitions, and implementation - starting with a review of green accounting's origins and development, the paper explores several academic meanings of the term before focusing on how it has helped bring social and environmental costs and benefits into traditional financial accounting. Additionally, it differentiates between environmental accounting and green accounting- highlighting the differences in their respective spheres of influence; financial accounting, management accounting, and external reporting are all part of green accounting, which is a systematic approach to accounting that aims to improve both financial and environmental consequences. Green accounting procedures have a favourable effect on financial performance and environmental transparency, as the paper shows empirically and then it goes on to analyse green accounting implementation in sustainable company operations. To aid in decision-making and encourage environmental sustainability - it also presents a conceptual model for green accounting that incorporates multiple indices. Lastly, the research highlights the significance of being sensitive while implementing green accounting methods and suggests more research to create practical tools that take stakeholder viewpoints and environmental hazards into account. In sum, the research shows that green accounting is essential for businesses to be more eco-conscious and for sustainable development initiatives to progress.

Given the importance of the ecological component as part of the Internet of Things (IoT) green city platform, it is necessary to constantly monitor the ecological situation in the cities and sub-urban areas. The Kyiv city (Ukraine) has been chosen as a test subject for the study. As a part of sustainability process management systems, we focused on modelling and analysis of the green city service systems. Objective of the study is to research and compare various economic and ecological data from large cities; outline the scope of the green city model that is used for web service design, which is part of larger internet of things sustainable information system platform. The following categories of data had been processed, but not limited to the total cost of the system, the total loss of a natural resource, the amount of investment in restoration or maintenance, the cost of natural materials, oxygen supply, the price of conversion for the exploitation or destruction of a natural resource, land prices dynamics, the tax on the restoration of the territory, the total economic benefit from the territory and the volume of CO2 emissions. Green City e-service platform has been constructed to enable the users to calculate the net cost, losses associated with natural resources available, and replenishment costs, both per unit of area and per unit of time. One of the most important outcomes of the service presented in this paper is the correlation between the urbanization processes (the increase in pollution, densification of buildings, the formation of agglomerations, new transportation, and infrastructure development) and their impact on the overall state of local ecosystems. The presented process management and monitoring service can further be enhanced to create a dynamic forecasting and situational assessment system as part of a green city management platform.

Published: November 2024

Mikrobiyal yakıt hücreleri (MYH), organik bileşiklerin bağları arasında bulunan kimyasal enerjiyi, aneorobik ortamda mikroorganizmaların katalitik reaksiyonları ile elektrik enerjisine dönüştürebilen kimyasal reaktörlerdir. Atık su arıtım sistemlerinin mevcut maliyetlerini azaltmak ve biyolojik parçalanabilir organik maddeler yönünden büyük bir enerji potansiyeli bulunan kentsel atıksuların hem değerlendirilmesi hem de çevreye olan kirletici etkilerinin azaltılması için bu sistemlerin geliştirilmesi önem arz etmektedir. MYH hücrelerinde anot elektrotu olarak kullanılan malzemenin yapısı, mikroorganizmaların anoda tutunmasını, substratın oksidasyonunu ve elektron transferini doğrudan etkilemektedir. Bu çalışmada MYH’de kullanılmak üzere üç boyutlu, makrogözenekli yapıda bulunan nikel köpük (NK), mikroorganizmaların yüzeyde tutunarak iyi bir elektriksel bağlantı sağlaması için indirgenmiş grafen oksit (rGO) ile kaplanmış ve elektron üretebilen bakteri türlerinin yüzeyde tutunmasını artırmak için en uygun molibden (Mo) yükleme yöntemi belirlenmeye çalışılmıştır. Ayrıca Mo yüklemelerinde, yükleme öncesi H2 gazı ile ısıl işlemin ve hidrotermal yöntemde indirgen olarak etilen glikol (EG) kullanımının etkileri araştırılmıştır. Çalışma sonucunda başlangıç çözeltisine EG eklemenin Mo yüklemesini artırdığı, H2 gazı geçirilmesinin ise yüzey morfolojisini bozduğu gözlemlenmiştir. Yapılan çalışma sonrası SEM görüntüleri ve EDS analizleri incelendiğinde en homojen yüzey morfolojisinin ve en yüksek verimin kütlece %84,39 oranında Mo içeren NK/rGO/Mo-E numunesinde olduğu gözlenmiştir.
Multiwavelength laser safety calculations: Case studies in supercontinuum lasers
Authors: Reilly Judi , Spencer Melissa , McWilliams Fred
Published: November 2024

Determination of appropriate eye protection is relatively straight forward for a monochromatic laser system. In non-linear optics that result in wavelengths over a broad spectrum, the calculations become more complex. In the extreme case, supercontinuum lasers emit light energy in a very broad wavelength range, making calculations of MPE quite difficult. Worse, since the these “laser rainbows” often cover the entire visible spectrum, eyewear must be carefully selected such that the users can still see while wearing it. An overview of laser safety calculations in systems of increasing complexity is presented along with a method for calculating the MPE for a laser with an arbitrary spectral content (broad wavelength range or discrete wavelength) as well as a method for determining the appropriate laser eye protection for such a laser. In addition, other novel methods of protection are presented.
