Peanut shell has a high cellulose content as a carbon source which can be used as a basic ingredient for making activated charcoal. Research on peanut shells used as activated charcoal aims to determine the effect of contact time and pH on reducing levels of metal ions Ca2+ and Mg2+ in water. The research was conducted using contact time variables (30, 60, 90, 120, and 150 minutes) and pH (4, 5, 6, 7, and 8). Measurement of adsorbed metal levels was determined by using an Atomic Absorption Spectrophotometer (AAS). The research results obtained showed that variations in contact time could reduce Ca2+ levels by 77.46% -84.89% and Mg2+ by 86.88%-88.91%. Adsorbents with variations in pH can reduce Ca2+ levels by 63.48%-88.74% and Mg2+ by 90.35%-94.49%. The best conditions for the absorption of Ca2+ and Mg2+ ions were a contact time of 60 minutes and pH 4. The adsorbent was applied to reduce Ca2+ and Mg2+ levels in water with different hardness levels. The results of the analysis of water samples from two different locations had Ca2+ levels of 94.180 mg/L and 210.20 mg/L, while Mg2+ levels were 13.536 mg/L and 17.420 mg/L. The percentages of Ca2+ adsorption for the two samples were 96.19% and 77.08%, and the percentages of Mg2+ adsorption for the two samples were 21.16% and 10.63%. Carbon from peanut shells activated with sodium acetate has the potential to be used to reduce hardness in water.

Tofu wastewater contains a lot of protein therefore it is easily degraded to produce foul odors and harmful gases due to microbes. Protein levels can be reduced through the electrocoagulation method which is equipped with adsorption. The purpose of this study is to reduce the value of turbidity, TSS, and COD in tofu wastewater due to the influence of voltage in the electrocoagulation process which is equipped with an adsorption process. This research was conducted with an electrocoagulation process at a rate of 250L/min with voltage variations of 15, 20, and 24Volt in a 10L tank containing 3 pairs of aluminum (Al) electrodes connected with direct current. The output water from the electrocoagulation process flows into the settling basin and flows into the adsorption tank containing activated carbon adsorbent. Both of these continuous processes were the innovation of this research. Sampling was conducted every 10 minutes for analysis of turbidity, TSS, COD, and pH. The results of the output water analysis from the electrocoagulation process after passing through the precipitation and adsorption processes show that increasing the voltage results in the decrease of turbidity, TSS, and COD values, however, increased efficiency and pH. Thus, a voltage of 24V with a flow rate of 250mL/min resulted in the highest efficiency of the voltage variations (15, 20, and 24V) with a process time of 90 minutes with a turbidity impurity reduction efficiency value of 45.42% with a value of 41.36 NTU from 75.22NTU, TSS 91.42% with a decrease to 1827mg/L from 21288mg/L, and COD 55.56% with a COD value of 9600mg/L from 21600mg/L, and a process output water pH of 4.91, as well as a reduction in aluminum electrode weight of 1.024grams.

Sulfated silica catalyst is a solid acid catalyst which in its application is used to accelerate esterification reactions. The purpose of this study was to determine the effect of calcination temperature and increasing the amount of catalyst on the effectiveness of silica as a catalyst in the formation of methyl oleate through esterification reactions. The synthesis of sulfuric acid catalyst from rice husk ash went through several stages, including preparation of raw material for rice husk ash, production of silica using the sol-gel method, manufacture of silica-based acid catalysts and characterization of the sulfated silica catalyst. The acid catalyst was prepared using impregnation method with sulfuric acid and calcined at various temperatures of 500, 600, 700 and 800oC. The characterization of the acid catalyst formed includes ionic capacity, catalyst performance in the esterification reaction, and the determination of the bond characteristic functional groups using FTIR. The results of ion capacity analysis showed that the highest acidity value was found in the sulfated silica catalyst calcined at 600oC of 0.372 mmol/gram. Testing the performance of the catalyst in the esterification reaction with a ratio of 4:1 (methanol:oleic acid) obtained an ester conversion of 38.89% using a catalyst of 30% of the amount of oleic acid. Identification results using FTIR show that sulfate ions have chemically interacted with silica at around 1103.28 cm-1

Unveiling the alliance between corporate board composition and earnings management through meta-analysis
Authors: Kaur Amandeep , Maheshwari Girish Chandra , Singh Archana
Published: August 2023

Misconduct in the financial sector, such as earnings management, has garnered significant attention from researchers due to the peculiarities of managers in financial reporting. Effective corporate boards have the potential to limit managerial opportunism in this regard. However, the existing literature yielded inconclusive results. Therefore, the present study aims to examine the influence of corporate board characteristics on earnings management through meta-analysis. The dataset comprises 72 published empirical studies with 3,66,417 firm-year observations. A two-step methodology is adopted following the PRISMA guidelines proposed by Moher et al. (2009) and the meta-analytic technique propounded by Hedges and Olkin (2014). The major findings of the study uncover that active, gender-diverse and larger corporate boards are most influential in controlling earnings management practices. Furthermore, different discretionary accrual measures, corporate governance systems, and the International Financial Reporting Standards (IFRS) adoption moderate the association between earnings management and board composition. The study provides a quantitative generalization to the inconclusive outcomes of published empirical studies from different timeframes and jurisdictions. The findings may help academicians and researchers to develop a holistic understanding of the impact of corporate boards on earnings management. This is one of the first studies to undertake a meta-analytic review of the association of board gender diversity and board activity as board characteristics with earnings management.
Predicting hotspots for disease-causing single nucleotide variants using sequences-based coevolution, network analysis, and machine learning
Authors: Zheng Wenjun
Published: August 2023

To enable personalized genetics and medicine, it is important yet highly
challenging to accurately predict disease-causing mutations from the
sequences alone at high throughput. To meet this challenge, we build
upon recent progress in machine learning, network analysis, and protein
language models, and develop a sequences-based variant site prediction
workflow based on the protein residue contact networks: 1. We employ and
integrate various methods of building protein residue networks using
state-of-the-art coevolution analysis tools (e.g., RaptorX,
DeepMetaPSICOV, and SPOT-Contact) powered by deep learning. 2. We use
machine learning algorithms (e.g., Random Forest, Gradient Boosting, and
Extreme Gradient Boosting) to optimally combine 13 network centrality
scores (calculated by NetworkX) with 7 other network scores calculated
from the contact probability matrices to jointly predict key residues as
hot spots for disease mutations. 3. Using a dataset of 107 proteins rich
in disease mutations, we rigorously evaluate the network scores
individually and collectively in comparison with alternative
structures-based network scores (using predicted structures by
AlphaFold). By optimally combing three coevolution analysis methods and
the resulting network scores by machine learning, we are able to
discriminate deleterious and neutral mutation sites accurately (AUC of
ROC ~ 0.84). Furthermore, by combining our method with a
state-of-the-art predictor of the functional effects of sequence
variations based on large protein language models, we have significantly
improved the prediction of disease variant sites (AUC ~
0.89). This work supports a promising strategy of combining an ensemble
of network scores based on different coevolution analysis methods via
machine learning to predict candidate sites of disease mutations, which
will inform downstream applications of disease diagnosis and targeted
drug design.
Study on the characteristics of ecological network and critical areas of ecological restoration in Hebei-Tianjin coastal wetlands
Authors: Wang Feng , Liu Jintong , Fu Tonggang , Gao Hui , Qi Fei , Gao Yue , Zhao Liang
Published: August 2023

Coastal wetlands are crucial ecosystems at the interface between land
and sea. In the context of economic development and urbanization, these
wetlands face challenges such as reduction in area and fragmentation.
Ecological networks can connect fragmented habitats, creating corridors
for material, information, and energy transmission. This is vital for
maintaining biological and landscape diversity and ensuring the healthy
development of ecosystems. However, there is currently no research on
the ecological networks in the Hebei-Tianjin coastal wetlands. In this
study, the morphological spatial pattern analysis (MSPA) method is
employed to identify wetlands sources, while the minimum cumulative
resistance (MCR) model is used to extract potential ecological
corridors. By combining these with existing river corridors, the
ecological network of coastal wetlands in Hebei and Tianjin is
constructed, and regional network characteristics are analyzed. Critical
areas of ecological protection and restoration are determined, including
important ecological corridors, ecological pinch points, and ecological
breakpoints. The results showed that: (1) The ecological network of
Hebei-Tianjin coastal wetlands consisted of 38 ecological sources, 171
potential ecological corridors, and 399 river corridors, with a total
area of 851.31 km2. (2) Key ecological protection and restoration areas
were proposed, including 35 crucial potential wetlands ecological
corridors, 343 ecological pinch points, and 99 ecological breakpoints.
Targeted restoration of these critical areas could significantly improve
the connectivity of wetlands ecological networks. (3) At present,
priority should be given to protecting critical ecological corridors and
existing river corridors with high similarity to potential ecological
corridors. The findings of this study can provide a scientific basis for
the network construction and protection of Hebei-Tianjin coastal
wetlands.

Objectives: To investigate the oral symptoms of COVID-19 ’s “positive”
group in Suining City after the comprehensive liberalization of epidemic
prevention and control measures in China. To explore the related
influencing factors of symptom differences and provide reference for the
treatment of patients in the post-epidemic era. Methods: An online
survey based on a random sample of 25 questions. Results: 1768 valid
questionnaires were collected. The data showed that 363 people had oral
problems after an infection with novel coronavirus. The oral problems
after SARS‐CoV‐2 infection mainly focused on gingiva swelling or
bleeding (38.57%), toothache (37.74%), bad breath (27.55%), oral
ulcer (30.30%), abnormal taste (24.24%) and some infected people had a
variety of oral symptoms. A small number of infected people also have
other oral problems. The incidence of oral symptoms was significantly
correlated with sex, age, educational level, place of residence,
smoking, basic diseases, long-term saline gargle and vaccination of
COVID-19 vaccine. In addition, the age, place of residence, smoking
history, basic diseases, and vaccination also showed significant
differences in prognosis. Conclusions: In the post-epidemic era, the
most common oral problems are gingiva swelling or bleeding, toothache,
bad breath, oral ulcer, and abnormal taste. And maintaining good living
habits is the basis for promoting disease recovery and oral health.
Enhanced upper ocean warming projected by the eddy-resolving Community Earth System Model

Published: August 2023

Ocean warming is a key factor impacting future changes in climate. Here
we investigate vertical structure changes in globally averaged ocean
heat content (OHC) in high- (HR) and low-resolution (LR) future climate
simulations with the Community Earth System Model (CESM). Compared with
observation-based estimates, the simulated OHC anomalies in the upper
700 m and 2000 m during 1960-2020 are more realistic in CESM-HR than
-LR. Under RCP8.5 scenario, the net surface heat into the ocean is very
similar in CESM-HR and -LR However, CESM-HR has a larger increase in OHC
in the upper 250 m compared to CESM-LR, but a smaller increase below 250
m. This difference can be traced to differences in eddy-induced vertical
heat transport between CESM-HR and -LR in the historical period.
Moreover, our results suggest that with the same heat input, upper-ocean
warming is likely to be underestimated by most non-eddy-resolving
climate models.

Em oposição à tradição que considera a Educação como um campo de aplicação da psicologia, argumentamos que existem contribuições mútuas entre as duas esferas do conhecimento. A reciprocidade é entendida como o processo de interação recíproca, interdependência e cooperação, solidariedade e ajuda mútua. A mutualidade entre a Educação e a Teoria das Representações Sociais consiste no movimento que estimula os estudos no contexto brasileiro, especialmente os que foram desenvolvidos no Centro Internacional de Estudos em Representações Sociais e Subjetividade - Educação (CIERS-ed). As análises realizadas sobre as contribuições da Teoria das Representações Sociais à Educação destacam o aumento das pesquisas que consideram a produção de conhecimento a partir de realidades sociais contextualizadas, bem como a importância da subjetividade dos educadores e aprendizes. Ao mesmo tempo, a Educação vem oferecendo às pesquisas sobre representações sociais um progresso que vai do diagnóstico à práxis, guiado principalmente por abordagens críticas e políticas do pensamento educacional.

Este artigo tem como objetivo compreender as experiências do brincar a partir de um grupo de crianças e seus educadores, em uma Comunidade de Aprendizagem, situada no Distrito Federal (DF). Como fundamentação teórica e metodológica, recorre-se, principalmente, aos estudos psicanalíticos de Freud e de Winnicott. A pesquisa de campo consistiu em dois dias de observação participante; quatro oficinas de rabiscos com uma turma de crianças - com idades entre oito e 12 anos - e sua educadora; e uma roda de conversa com educadores. A ênfase é dada, neste texto, nas vivências da segunda oficina e em trechos da roda de conversa, explorando a capacidade de criar e de brincar com as palavras. Com isso, foi possível ressaltar a importância de um brincar criativo e espontâneo nas relações humanas. A conclusão é que este brincar não se restringe à infância, por se tratar de uma experiência própria ao humano, sendo necessário que os espaços escolares e comunitários estejam abertos à sua manifestação e ampliação.
Urban Development Management on an Eco-Innovation Basis: Content and Mechanism
Authors: Karpova N. V.
Published: August 2023

The concept of sustainable urban development emphasizes the importance of using innovative ap-proaches in solving environmental problems that manifest themselves in actropogenically altered ecosystems. Urban development management on such a basis includes the development and imple-mentation of innovative projects that are comprehensively focused on achieving long-term growth, improving the quality of life and protecting the environment. To achieve these goals, it is necessary to form a mechanism for managing urban development on an ecoinnovation basis, based on the application of a process approach and the formation of fundamentally new institutional structures. In this context, eco-innovation clusters can become key elements within the framework of the sustain-able urban development management mechanism.

Agricultural production on the territory of LLC "Rus" of the Semiluksky district of the Voronezh region was carried out without taking into account the factor of soil erosion, which led to gradual degradation of land and an increase in the area of arable land, characterized by a strong soil washout of more than 50% of the arable land. The analysis of the agricultural production of the enterprise, natural and climatic factors, soil conditions, as well as the conducted erosion assessment of arable land showed that the land use area is in urgent need of a complex of land management measures aimed at combating erosion. To create favorable conditions for agricultural production, we have de-veloped a set of land management measures for territorial organization, taking into account the man-ifestation of soil erosion. The planned planned measures create a solid foundation for sustainable agriculture, taking into account the factor of soil erosion. . Organization and arrangement of the territory on the anti-erosion principle will prevent the negative impact of erosion processes, improve the agroecological situation on the territory of the enterprise, increase the environmental sustainability of the territory.

The progress of civilization depends on both science and ethics, on two different ideas. Unlike ethics, which deals with moral principles and ideals that guide human behavior, science is based on logical argumentation, empirical data, and methodical testing. However, as science develops, it often raises ethical questions that must be addressed. As a result, science and ethics are intertwined and both are essential for the moral and long-term advancement of science. This research examines the results of two interconnected processes: the quick development of science and technology and its moral ramifications, or the harm it does to people’s lives all around the world. The writers highlight the need for a qualitative shift in attitudes toward nature and society as a whole in order to address environmental challenges and remove the threat of a global ecological disaster by analyzing the substance and impact of these processes.

Authors: Shafira Ersa , Gusnita Wiwik
Published: August 2023

Nastar is a semicircular round pastry with a diameter of 2 cm, made from a dough of wheat flour, butter, and eggs with pineapple jam filling. White sweet potatoes are more directed to the development of flour and starch because the color of the flour produced is more like wheat germ, and brightly colored sweet potatoes tend to have better starch levels. So that white sweet potato flour can be used in making nastar. This study aims to analyze the effect of using white sweet potato flour as much as 15%, 30%, and 45% on the quality of the shape, color, aroma, texture and taste of pineapple produced. This type of research is a pure experiment with the Complete Randomized Design method. The data used were primary data obtained directly from 3 expert panelists by filling in the organoleptic test format on the quality of pineapple with the influence of the use of white sweet potato flour. The data obtained is then tabulated in tabular form and carried out Variance Analysis (ANAVA), if Fh>Ft then continued with the Duncan Test. The results showed that there was a significant influence of the use of 15%, 30%, and 45% white sweet potato flour on the quality of color (golden yellow at the top and brownish yellow at the bottom), aroma (fragrant), and nastar taste (sweet taste and distinctive taste of sweet potatoes). The best result of the pineapple quality test with the use of white sweet potato flour is 15%.

Nastar is a type of cookie made from a dough of flour, butter and eggs filled with pineapple jam with a brittle, crunchy, slightly gritty texture and sweet taste. The background of this research is because there is no utilization of corn flour raw material in nastar processing. Utilization of corn flour aims to reduce dependence on wheat flour, as well as add nutritional value to nastar. Based on this, this study aims to determine the effect of corn flour substitution of 0%, 15%, 30%, and 45% on the quality of shape, color, aroma, texture and taste of the resulting nastar. This type of research is a pure experiment using a completely randomized design (CRD) with three repetitions. The type of research data is primary data sourced from 3 panelists. Data were analyzed using analysis of variance (ANAVA). If there is a significant effect then proceed with Duncan's test. The results of the study showed that the substitution of nastar corn flour had an effect on the quality of the fragrant aroma of corn and the taste of nastar corn because fcount > ftable. While the shape (neat and uniform), texture, color, and sweet nastar taste did not show a significant effect. The best overall score is uniform shape 3.78 (X2), neat shape 3.78 (X1), color 3.78 (X2), sweet corn nastar aroma 2.89 (X3), texture 3.89 (X2) taste sweet nastar 3.67 (X3). The best result in this study was treatment X1 with 15% corn flour substitution.

O desenvolvimento de modelos com alta cobertura e baixo custo são fundamentais para o monitoramento dos fluxos de dióxido de carbono (CO2) nos ecossistemas. O estudo objetivou validar um método para determinação de fluxos de CO2 utilizando dados multiespectrais em áreas de caatinga preservada e em sucessão ecológica. Aplicou-se o Índice de Sequestro Florestal de Carbono (CO2flux) para a modelagem espectral em 20 cenas do sensor OLI (Landsat-8). No processo de validação do modelo, dados de fluxos de CO2 medidos em superfície com o uso de torres micrometeorológicas foram utilizados. De acordo com o momento de passagem do satélite Landsat-8, foram utilizadas diferentes escalas temporais dos dados de fluxo de CO2 da torre considerando intervalos de meia hora, 1 (uma) e 2 (duas) horas. O teste Shapiro-Wilk foi utilizado para verificar normalidade dos dados, e como maioria das variáveis não apresentaram distribuição normal, os dados foram submetidos ao teste de correlação de Spearman, e em seguida foi recomendado o melhor modelo analisando o seu coeficiente de determinação (R2) e a raiz quadrada do erro médio (RSME). O índice espectral CO2flux mostrou-se compatível para avaliação dos parâmetros de estimativas dos fluxos de CO2 na caatinga quando comparados com fluxos de CO2 do pixel correspondente a localização da torre, com correlações apresentando valores variando de ? = -0,86 a ? = -0,72. O modelo proposto apresentou alta correlação com os dados observados obtendo R2 = 0,81 e RSME = 1,6, constatando um ajuste eficiente para a avaliação dos fluxos de CO2 e grande potencial no uso de imagens multiespectrais para o monitoramento do fluxo de CO2 capturando os efeitos das mudanças sazonais da dinâmica dos fluxos de carbono.
The effects of cold stimulation and exercise on human health
Authors: Tian Jie , Li Jiangli , Zhang Yunbo , Yang Fengjuan
Published: August 2023

Cold stimulation and exercise are two independent stimulus variables, each yielding unique impacts on human health. However, in many cases, individuals often encounter both factors simultaneously, particularly in colder regions where outdoor physical activity is prevalent. Despite numerous studies exploring the effects of cold exposure and exercise independently, only a limited number of comprehensive reviews have evaluated their combined influence on health. This review aims to bridge this gap by meticulously examining the potential benefits and detriments of both cold stimulation and exercise on human health. Specifically, the review focuses on their impacts on cardiovascular, respiratory, and immune function, as well as the favorable effects of moderate exercise on the human body. While evidence suggests that cold exposure can enhance health outcomes in certain disease contexts, it also poses risks, particularly for vulnerable populations. Furthermore, while moderate exercise is generally beneficial, engaging in physical activity in cold weather conditions can increase the risk of hypothermia, frostbite, and other cold-related injuries. Consequently, there is an urgent need to develop safe and effective guidelines for exercising in cold weather, particularly for individuals living in colder regions. This review emphasizes the necessity for further research on the combined effects of cold stimulation and exercise, with the goal of informing public health policies and guidelines for physical activity in cold weather conditions.

Published: August 2023

Background

In some developing countries, people have little knowledge about the causes of diabetic foot ulcers. Therefore, public health education for patients on these conditions is a prerequisite for effective pharmacological treatment. Diabetic foot ulcers are a complex symptom of diabetes and are hard to cure due to the lack of efficacious medicine and alternative treatment approaches. Vitamin A (VA) is known to have potent biological functions, including skin repair and immunoregulation. However, the potential pharmacological effects and molecular mechanisms of VA on foot ulcers are still to be discovered.

Methods

By using bioinformatic/computational analyses, including network pharmacology, gene ontology and the Kyoto Encyclopedia of Genes and Genomes enrichment analysis, we aimed to identify and reveal the pharmacological targets, molecular mechanisms, biological functions, and signaling pathways of VA in the treatment of diabetic foot ulcers.

Results

A total of 66 intersection genes were identified as candidate targets of VA, which are related to diabetic foot ulcers. Therein, 18 core genes/targets, namely JUN, MAPK1, THRB, MAPK14, MTNR1B, CXCR3, ESR1, AR, HDAC1, IL-10, CNR1, DRD2, EGFR, ADRA2A, CCND1, RXRB, RARA, and RXRA, were further identified. Furthermore, the biological processes, cell components, and molecular functions which may underlie the effects of VA against diabetic foot ulcers were characterized.

Conclusion

Based on our findings, we concluded that the pharmacological effects of VA on diabetic foot ulcers primarily involve the promotion of cellular regeneration and proliferation and the inhibition of inflammatory response. The core genes/targets may potentially serve as promising biomarkers for the diagnosis of diabetic foot ulcers.
