Authors: Brito Roberta Da Silva , Sampaio Dioniso De Souza , Dias Carmen Gilda Barroso Tavares , Pereira Luiz Felipe
Published: October 2022

Conchas de moluscos bivalves são fontes biológicas de carbonato de cálcio, que é utilizado como matéria-prima em diversos setores como agricultura, construção civil, farmacêutico, produção de plástico e biomateriais. A maricultura, em especial a malacocultura, vem se expandido mundialmente e em 2018 a produção de moluscos, principalmente os bivalves, foi de 17,7 milhões de toneladas em peso vivo. Apesar de ser uma forma de produção relativamente nova no norte do Brasil, no Pará, a malacocultura vem acompanhando esse ritmo de crescimento, produzindo 39.850Kg em 2018. Associada a essa expansão, existe a preocupação quanto ao descarte dos resíduos sólidos, por tanto o presente trabalho visa oferecer uma solução baseada na utilização de conchas descartadas no município de Augusto Corrêa - PA, para extração de CaCO3. O processo de obtenção iniciou a partir da higienização das amostras com hipoclorito de sódio para remoção de resíduos superficiais, e posterior secagem por 30h a 60ºC. Para obter o pó das conchas de ostras (PCO), as amostras foram prensadas e depois moídas no moinho de bolas, de onde saíram com a granulometria de até 74 ?m. O material obtido passou por tratamento químico com NaOH e HCl. A concha e o PCO foram caracterizados por DR-X, onde o polimorfo calcita foi apresentado de forma majoritária, e por MEV/EDS para o mapeamento dos seus constituintes químicos. Após o beneficiamento das conchas, o material obtido foi incorporado a matrizes poliméricas para produção de filmes, placas e recipientes, comprovando a viabilidade do uso das conchas como matéria prima.
Impacts of the African CFA Franc devaluation on cereal yields and food security in West Africa
Authors:   University of Connecticut, Ndiaye MF
Published: October 2022

In January 1994, all member countries of the African Financial Community (CFA) devalued 50 percent of their local currency in order to regain their competitiveness on the world market and increase their exports for sustainable economic growth. Nevertheless, a common side effect of devaluation is a one-off rise in prices leading to a decline in local purchasing power and a scarcity of goods. Consequently, the policy makes it more difficult for the local population to buy or access their usual amount of cereals for consumption. Especially when staple foods account for 70-80% of the daily diet in the region. In addition, any prolonged shortage of cereals on the local market could compromise food security and lead to the common form of malnutrition known as under-nutrition. Therefore, in the absence of randomization of the treatment, a difference in difference (DID) quasi-experimental method is applied to estimate the effects of the CFA devaluation on member countries' cereal yields and food security. The findings show a slight increase of 172 kg per hectare in cereal yields in the devalued area. In addition, to assess food security, countries' food balance sheets were used to evaluate the daily per capita food supply from major cereals consumed locally. The results showed an increase in the daily supply of maize (120 kcal per capita) and rice (129 kcal per capita) in the CFA area, as confirmed in previous studies and a slight decline of the daily supply of sorghum (65 kcal per inhabitant) and millet (26 kcal per inhabitant). Other factors such as strong demand for maize imports, reduced rice import taxes and a substitution effect between millet and rice in devalued countries have contributed to the results. In conclusion, the devaluation of the CFA currency has not contributed to food insecurity. However, it has changed the basic food consumption behavior of CFA region local population with higher rice and maize consumption.

The transition in eating behaviour toward a diet rich in calories and low in vegetables is a major factor responsible for the rapid increase in the incidence of obesity and diabetes. The research aimed at investigating the effect of a high-calorie diet and vegetables on feeding behaviour, weight gain and blood sugar in male Wistar rats. The vegetables were dried, blended, and preserved in airtight containers. Thirty male Wistar rats weighing an average of 127.4 g were housed in 6 cages with 5 rats in each cage. There were six groups comprising the positive control which was fed standard rat feed and water, also the negative control which was given a high-calorie diet (high-fat feed and sugar water) and four treatment groups. The four treatment groups were fed on a high-calorie diet with a 5 % concentration of either Corchorus olitorius, Crassocephalum crepidiodes, Amaranthus hybridus or Solanecio biafrae respectively. Water (or sugar water) and feed intake of each group were measured and recorded daily. Weekly consumption of water and feed was computed for the entire 5 weeks of the experiment. The fasting blood sugar and weight of the test rats were recorded at baseline and weekly. Oral glucose tolerance test and serum insulin were determined at the end of the experiment using blood samples from the test rats. All results were analysed using ANOVA at p≤0.05 and means were separated with the use of Duncan’s multiple range tests (SPSS 20.0). The high-fat feed was significantly different from the standard rat feed in the composition of fat (26.79 g) and calories (422.67 kcal). The negative control and the treatment groups got adapted to feeding on the high-calorie diet before the end of the experimental period. Water and feed intakes of the positive control were only significantly higher during the first three and four weeks, respectively. At the end of the experiment, the positive control had the highest weight gain of 22 g which was significantly different at p≤0.05. C. crepidioides and S. biafrae significantly lowered the blood sugar (62.75 and 62.50 mg/dL) of the test rats. A. hybridus prevented insulin resistance by the attainment of peak level at 30 min alongside the positive control. There was a significant increase in the insulin level of the negative control while the vegetables prevented increased production of insulin.

Published: October 2022

Background: Entomopathogenic fungus (EPF) can provide safe and efficient insect pest management. Temperature, relative humidity (RH), light, air, nutritional content and host physiological condition are all elements that impact the proliferation and virulence of entomopathogenic fungus. The current study aimed to evaluate the effect of different temperatures on germination, growth, sporulation of entomopathogenic fungi and on their pathogenicity against Tetranychus urticae Koch was studied. Methods: Laboratory experiment was conducted to study the impact of temperature on germination, radial growth and sporulation of five entomopathogenic fungal isolates viz., B. bassiana (Bb 111), B. bassiana (Bb 112), B. bassiana (Bb 113), B. bassiana (Bb 114) and M. flavoviride var. minus. Virulence of five entomopathogenic fungal isolates subjected to different temperature against T. urticae also evaluated through laboratory bioassay techniques. Result: Results one valuation of entomopathogenic fungal isolates with four different temperatures at 20°C, 25°C, 30°C and 35°C showed that 25°C was optimum for germination, radial growth and sporulation. Maximum germination was recorded with the entomopathogenic isolate Beauveria bassiana (Bb 112) (95.67%) at 25°C. Interestingly, at 25°C all the B. bassiana isolates showed a radial growth of more than 50 mm with the highest recorded as 84.67 mm by B. bassiana (Bb 111). Maximum spore production was observed with B. bassiana (Bb 112) at 25°C (1.63 x 106 spores ml-1) followed by B. bassiana (Bb 111) (1.45 x 106 spores ml-1). It was also the most pathogenic against T. urticae at 25 and 30°C. The isolate Bb112 grown at 25°C caused higher mortality of 97.57 per cent against T. urticae. From the findings the isolates of B. bassiana (Bb 112) and (Bb 111) were found promising bio control agent against T. urticae with varying temperature.

The concept of generation is used to describe a group of people who were born in the same years and experienced similar social events, troubles and obligations under the conditions of the same age. Generational formation is generally classified according to age and sociological phenomena. However, today, factors such as technology, differentiating social values, changing career perceptions, education and working conditions reveal the necessity of evaluating the classification according to different dimensions. The field of professional competence is an important issue all over the world. Especially with the technology that has developed and continues to develop in recent years, the qualifications of teachers in this field are important. We live in the age of technology. The aim of this study is to determine the opinions of teacher candidates studying at the Faculty of Education about the ‘Media Literacy’ course. For this purpose, the case study method, one of the qualitative research approaches, was used. 71 students studying in the Faculty of Education at the university constituted the study group of the research. Semi-structured interview questions prepared by the researchers were used.

El ritmo y la palabra o para una poética de la música salsa
Authors: Becerra Mayorga Witton
Published: October 2022

La salsa se ha desarrollado ampliamente como estilo musical del Caribe
hispánico. El propósito principal de este libro consiste en indagar la poética
de las canciones de salsa y presalsa. Este término alude a la música de Cuba y
Puerto Rico que precede y afecta el paradigma musical y literario de la salsa
que se creó en Nueva York.
El principal problema que se resuelve acá es cómo la salsa y la presalsa toman
sus formas poéticas de la literatura española del siglo XVII y de los sonidos
residuales de las lenguas bantú que quedaron en los afrodescendientes del
Caribe llamados jitanjáforas. Otro aporte que hace este trabajo, al estudio de
estas músicas, es la categorización de las canciones como “canción salsa relato”,
“canción salsa poema”, y “canción salsa jitanjáfora”.
La metodología empleada en esta investigación se basa en los estudios de
canciones. Esta metodología es importante para el desarrollo de este trabajo
ya que ayuda a estudiar la poética de la salsa y la presalsa en casos específicos.
La investigación se completa con la teoría cultural para entender la salsa y la
presalsa como productos de la cultura popular.
El estudio del concepto de cultura, cultura popular y música popular son
fundamentales en la primera parte de este trabajo ya que son las bases teóricas
que configuran la investigación. Esto contribuye al estudio de cómo el uso
de la décima nace de la cultura popular y llega a la música puertorriqueña y
cubana y de allí pasa a la ciudad de Nueva York. La revisión sobre la cultura
popular y la música popular genera una aproximación al uso de las jitanjáforas
en la poesía de Nicolás Guillén y Luis Palés Matos y permite la explicación de
cómo se manifiesta también en la salsa y la presalsa.
Complementario a cómo surge la poética de la salsa y la presalsa, los estudios
particulares de las canciones sirven para comprender la configuración poética
de la salsa desde las canciones vistas desde el relato, el poema y las jitanjáforas.
El principal logro de este libro consiste en completar lo que se ha hecho sobre
la música salsa que no ha tocado la parte literaria, algo que se había hecho
parcialmente en algunos trabajos que estudian esta música y que, por tanto,
es la principal contribución de este trabajo. Desde el estado de la cuestión se
observa que lo que más se ha hecho, respecto al estudio de la salsa, está desde
lo etnomusicológico, por eso este libro va más allá a través del estudio de las
canciones como un estilo literario.
Mergers and acquisitions in Brazil and economic uncertainty shocks
Authors: Batista Alexandre Teixeira Norberto , Lamounier Wagner Moura , Mário Poueri do Carmo , Ferreira Bruno Pérez
Published: October 2022

In this paper, we have analyzed the sensitivity of the aggregate volume of Mergers and Acquisitions (M&A) in Brazil to fluctuations (shocks) in the Economic Uncertainty level from 2010 to 2021 under behavioral and neoclassical theoretical foundations on the M&A causes. We estimated a Vector Autoregressive (VAR) model with the volume of M&A announcements, the Brazil Economic Uncertainty Index (IIE-Br), and macroeconomic and market variables. There is evidence that the M&A announcements in Brazil can respond positively to an economic uncertainty shock. Thus, we contribute with empirical evidence to understand the role of macroeconomic factors, including economic uncertainty, in the future conduct of the M&A market.

Hybrid convolution network for medical images processing and breast cancer detection
Authors: Zaychenko Yuriy , Naderan Maryam , Hamidov Galib
Published: October 2022

In this paper, the breast cancer detection problem using convolutional neural networks (CNN) is considered. The review of known works in this field is presented and analysed. Most of them rely only on feature extraction after the convolutions and use the precision of classification of malignant tumors as the main criterion. However, because of the huge number of parameters in the models, the time of computation is very large. A new structure of CNN is developed — a hybrid convolutional network consisting of convolutional encoder for features extraction and reduction of the complexity of the model and CNN for classification of tumors. As a result, it prevented overfitting the model and reduced training time. Further, while evaluating the performance of the convolutional model, it was suggested to consider recall and precision criteria instead of only accuracy like other works. The investigations of the suggested hybrid CNN were performed and compared with known results. After experiments, it was established the proposed hybrid convolutional network has shown high performance with sensitivity, precision, and accuracy of 93,50%, 91,60%, and 93%, respectively, and requires much less training time in the problem of breast cancer detection as compared with known works.

Traumatic Subdural Hygroma Due to Injury of an Ommaya Reservoir: A Case Report
Authors: Sung Seung Bin , Kim Young Deok , Jeong Han-Gil
Published: October 2022

A 68-year-old male patient was transferred to the emergency department after a passerby found him lying on the road with a bicycle. He had been diagnosed with neurolymphomatosis in 2006 and had an Ommaya reservoir targeted to the right lateral ventricle via the right Kocher’s point for chemotherapy. His initial mental status was stuporous. Brain computed tomography (CT) showed multiple traumatic injuries. Seven days after admission, bilateral subdural hygroma (SDG) developed. We performed CT cisternography. The contrast was directly injected into the Ommaya reservoir and CT images were obtained. On cisternography, contrast leakage points were identified from the Ommaya reservoir. The patient underwent surgery for Ommaya reservoir removal and occlusion of the permanent tract of the Ommaya reservoir. This case shows a rare etiology of traumatic SDG and demonstrates the usefulness of CT cisternography to determine cerebrospinal fluid leakage from an implant.
A Field Study: Minimizing Gas Flaring Through Reuse to Produce Electricity and Petrochemical Products
Authors: Biheri Ghith , Amoura Ashrf , Elmaleh Khaled , Nouh Abubaker
Published: October 2022

A novel strategy has been implemented in Libyan oil companies to eliminate the environmental impact of gas flaring by utilizing the associated gas to produce electricity and petrochemical products. This strategy would have significant environmental and economic advantages. The primary purpose of the study is to investigate the scenarios that could further facilitate the reduction of natural gas pollution in one of the Libyan oil companies caused by flaring and its utilization in power stations.

More than 27% of the associated gas is flared daily in Libya due to an inability to monetize or store the associated gas. However, a new technique uses the flared gas to produce energy at a power station located approximately 30 miles from the oil fields. This power station has four units with a total capacity of 640 megawatts. In recent years, the power station was operated using crude oil, despite it having been designed to be operated by gas as well. It was found that it would cost much less to produce the electricity if natural gas were used instead of crude oil.

The evaluation demonstrated that switching from flaring the gas to reusing it to generate energy or create petrochemical products has significant environmental benefits. These benefits include a reduction in released toxic components and air pollution, which limits contribution to climate change and reduces health hazards, particularly in residential areas near the oil fields. In addition, this method of reusing flared gas exhibits some economic benefits, such as the ability to manufacture electricity from natural gas rather than costly crude oil. In addition, the associated gas can be used to optimize supply of products such as methanol, ethylene, and ammonia.

This research seeks to discuss and develop efficient and effective solutions to avoid flaring associated gas, which is considered a waste of valuable natural resources, and reuse it in order to maintain a clean environment and provide economic benefits by using the associated gas to produce electricity and supply it to various petrochemical businesses.
An Advanced Open-Source Software for the Design of CO2 Capture, Transport, and Storage Infrastructure
Authors: Ma Zhiwei , Chen Bailian , Pawar Rajesh J.
Published: October 2022

The design of optimal infrastructure is essential for the deployment of commercial and large-scale carbon capture and storage (CCS) technology. During the design process, it is important to consider CO2 capture and storage locations and CO2 transport pipelines to minimize the total project cost. SimCCS, first introduced in 2009, is an integrated open-source tool to optimize CCS infrastructure. The core CCS infrastructure design problem is structured as a mixed-integer linear programming problem in SimCCS by selecting the optimal pipeline routes, searching CO2 source capture and storage locations, and determining the corresponding amounts to meet desired capture targets. Multiple important and practical features have been added to the latest version of SimCCS (SimCCS3.0), including (1) the temporal model which enables the user to investigate the impact of the enhanced 45Q tax credits on CCS infrastructure and to implement dynamic evolution of CO2 point sources (decommissioning and shutting down existing facilities and opening of new facilities), and (2) the consideration of utilizing the existing CO2 pipelines. We demonstrate the newly developed features in SimCCS3.0 using one CCS infrastructure optimization case study. The results from these case studies reveal that the inclusion of those developed features is particularly useful to optimize the dynamic deployment of CCS projects. SimCCS3.0 is available for public use via GitHub.
Scaling Equations for Benchtop Laboratory Simulator of Wellbore Hydraulics
Authors: Alarfaj Mohammed Nabil , Zhang Wei , Mehrabian Amin
Published: October 2022

Determining frictional pressure losses along a wellbore annulus is the key to estimation of the wellbore equivalent circulating density. Flow-loop experiments are often used at smaller scales of flow to measure the frictional pressure losses. However, a complete set of scaling equations between the measured pressure drop in a flow loop device and the one occurring in the wellbore has not been reported in the literature.

This study applies dimensional analysis to make such connection while accounting for drill pipe rotation, eccentricity, and cuttings load in the annular flow of power-law drilling fluids. Simultaneous application of geometric, kinematic, dynamic, and rheological similarities allows for developing direct relations between the operational and flow quantities at the laboratory and wellbore scales of flow. For this purpose, the pertinent dimensionless groups are identified and set equal between the two flow scales.

Results indicate that scaling the two-phase flow of drilling fluid and cuttings entails nine (9) dimensionless groups. The obtained scaling equations provide the required volumetric rate of fluid and particles, the inner pipe rotation speed, as well as the fluid rheology and other design parameters of the flow-loop device to establish the full similitude with the corresponding wellbore hydraulics. In particular, the Reynolds number of cuttings necessitates introducing a constraint on the rheology of fluid to be used in the laboratory flow loop. Once all scaling requirements of the considered similitude are applied, the pressure gradient along the wellbore annulus can be obtained directly in terms of the measured pressure drop in the laboratory flow loop.

Background: The aim of the current study was to investigate current dental practice in operative dentistry in Jordan, and the relationship between evidence-based dentistry in caries research and decision making in clinical practice in operative dentistry.
Methods: The study was conducted through a survey of dentists in Jordan. The survey aimed to explore the degree of knowledge and practice of evidence-based dentistry in caries research the dentists possess regarding clinical decision making in operative dentistry.
Results: Nearly half of the surveyed dentists focus on the chief complaint of their patients (50.8%) rather than doing full mouth assessment. Nearly two-thirds of dentists (65.2%) treat lesions confined to enamel with operative treatment. Half of dentists use operative treatment when asked about the routine management of radiographically detected proximal caries confined to enamel. When treating incipient lesions, the majority (80.5%) use preventive treatment, and three-quarters of dentists treat deep dentinal caries by removing just the soft infected carious dentin, and treated old failed restorations with replacement.
Conclusion: clinical decision-making in operative dentistry is not based solely on evidence-based dentistry. Research findings are not translated clinically. To optimize relationship between evidence-based dentistry and clinical decision-making dental curriculum has to be updated and modified constantly.

Bismuth Oxyiodide (BiOI) hierarchical structures were fabricated from the solution route at room temperature (BiOI-R) and solvothermal synthesis (BiOI-S) in the presence of KI and ethylene glycol to improve the photocatalytic and adsorption ability for the removal of ciprofloxacin from the aqueous environment. In this study, BiOI was characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM), N2 adsorption-desorption isotherm (BET), UV-Vis absorption spectroscopy, and pH of the point of zero charge (pHpzc). It was observed that the BiOI-S has better adsorption and photocatalysis capacity as a result of having more surface area, higher light absorption ability, and lower band-gap energy than the BiOI-R. The response surface methodology was applied to optimize the conditions of contact time, BiOI dosage, ciprofloxacin initial concentration, and pH for ciprofloxacin adsorption and photocatalytic processes using BiOI-S. The results show that the optimum conditions of ciprofloxacin removal processes obtained as contact time of 90 min, BiOI-S dosage of 2 g/L, and initial ciprofloxacin concentration of 2 mg/L, solution pH of 4.5 for adsorption processes. Meanwhile BiOI-S dosage of 1.5 g/L, initial ciprofloxacin concentration of 3.5 mg/L, and contact time of 108 min were the best condition for photocatalytic degradation. Additionally, the adsorption isotherm and kinetic studies fitted the Freundlich isotherm and pseudo-second-order model, respectively. The ciprofloxacin adsorption capacity value for BiOI-S of 3.799 mg/g was obtained and photocatalytic degradation of ciprofloxacin by BiOI-S followed the pseudo-first-order rate reaction based on Langmuir-Hinshelwood kinetics.

Bosten Lake is the main drinking water source, fishing area and grazing area for residents in Korla. The pollution of phthalate esters (PAEs) in water has attracted much attention, but limited research has been conducted on PAEs in Bosten Lake. The distribution of PAEs in 15 sampling sites of surface water in the autumn of 2021 was investigated to explore PAE pollution in Bosten Lake, and the risk was evaluated. Seventeen PAEs were detected by GC-MS after liquid–liquid and solid-phase purification. Results showed that 14 other PAEs, except for DMEP, BBP and DNOP, were detected in varying degrees. ΣPAE was 1.1023–4.5640 µg/L, and DIBP contributed the most. The PAE pollution in the lake was mainly derived from the living and industrial applications of surrounding towns. In the health risk assessment, the noncarcinogenic risk values (HQ) of the four PAEs, namely, DBP, DEP, DIBP and DMP, at each sampling site showed the trend of children > women > men, and the HQ values were less than 1. DEHP had carcinogenic risk, which was less than 10− 6, indicating that the effect of PAE in Bosten Lake on human health was very low and negligible.

Individuals with prodromal symptoms of Lewy body disease (LBD), such as rapid eye movement sleep behavior disorder (RBD), often showed imaging defects similar to patients. We examined dopamine transporter (DaT) single-photon-emission computed tomography (SPECT) and metaiodobenzylguanidine (MIBG) scintigraphy in 69 high-risk subjects with ≥ 2 prodromal symptoms (dysautonomia, hyposmia, and RBD) and 32 low-risk subjects without prodromal symptoms, whom were identified through a questionnaire survey of health checkup examinees. The high-risk subjects had significantly worse scores on Stroop test, line orientation test, and the Odor Stick Identification Test for Japanese than the low-risk subjects. The prevalence of abnormalities on DaT-SPECT was higher in the high-risk group than in the low-risk group (24.6% vs. 6.3%, p = 0.030). A decreased uptake on DaT-SPECT was associated with motor impairment, and MIBG scintigraphy defects were associated with hyposmia. The simultaneous evaluation of DaT-SPECT and MIBG scintigraphy may capture a wide range of individuals with prodromal LBD.

Sugarcane vinasse has been widely reported due to the improper management that pollutes the environment. In this study, a combined coagulation and sequencing batch biofilm reactor (SBBR) seems to be a novel improvement for the treatment of sugarcane vinasse. This research focused on the optimal conditions of coagulation and SBBR and determined the abatement efficiency of sugarcane vinasse in combined sequential wastewater treatment. The coagulation process destabilizes the colloids in the aggregation and separates the supernatant by sedimentation and filtration, resulting in the maximum COD reduction (79.0 ± 3.4%) and decolorization efficiency (94.1 ± 1.9%) under the optimum conditions. Sequencing batch reactor (SBR) is a fill-and-draw activated sludge system, whereas SBBR is an integrated SBR that suspends activated sludge and connects growth processes into a biocarrier-filled system. SBBR showed great synergistic degradability, decreasing 86.6 ± 4.3% COD concentration and 94.6 ± 3.8% decolorization at 3.0 g/L of substrate loading concentration. Furthermore, kinetic studies of SBBR revealed that the first-order kinetic model was the best fitting model. The SBBR reaction was further investigated by ultraviolet-visible spectrophotometry (UV–Vis). Then, SBBR followed by the coagulation process (SBBR–CP) achieved 97.5% of COD reduction and 99.4% of decolorization, which was better than the coagulation process followed by SBBR (CP–SBBR). This finding provides new insight into developing efficient combined sequential wastewater treatments in sugarcane vinasse.

Leishmaniasis is a vector-borne disease that affects several populations worldwide with the clinical manifestations in skin, mucous membranes, and internal organs and there are not any effective and available vaccines and conventional treatments are highly toxic. Quercetin is a kind of flavonoid with different biological effects including free radical scavenging and anti-microbial activity and this study is aimed to assess the Anti-leishmania and Anti-malarial effects of quercetin loaded phytosome and quercetin alone. In this experimental study, the in vitro activity of above drugs were measured using microscopically examinations and for evaluation the anti-leishmanial efficacy, the size of lesions were measured. Moreover the cytotoxicity of the treatments was evaluated on WI38 and J774 cell lines. Our results indicated that quercetin loaded phytosome and quercetin alone have acceptable anti-parasitic activity mostly at concentration of 400 µg/ml on both P. falciparium and L. major. The results of cytotoxicity revealed that the mentioned drugs have no effects on human cell lines and also have no hemolytic activity. The drug of choice for the treatment of leishmaniasis, in addition to killing the parasite, should not have a toxic effect on human cells and our results indicated that quercetin can be a valuable candidate for treatment of different kinds of leishmaniasis.
Fuzzy rough sets based on modular hememetrics
Authors: Zhang Guangxv , Yao Wei
Published: October 2022

In this paper, we introduce a notion of modular hemimetrics, an extension of hemimetrics and modular metrics, as the basic structure to define and study fuzzy rough sets by using the usual addition and subtraction of real numbers. We define a pair of fuzzy upper and lower approximation operators and investigate their properties and interrelations. It is shown that upper definable sets and lower definable sets are equivalent. Definable sets form an Alexandrov fuzzy topology such that the upper and lower approximation operators are the closure and the interior operators respectively. At the end, an application of the modular hemimetrics based fuzzy rough set to the acquisition of color gradient images is proposed.
