Published: June 2019

African gaint land snails are important as means of alleviating acute protein shortage in Nigeria livestock Industries. The present study aimed to study the influence of intensive and extensive management systems on the growth Performance of adult African Giant Land Snails (Archachatina marginata) was carried out in the wildlife domestication unit of the Department of Forest Resources and Wildlife Management, University of Benin, Benin City, Nigeria. Ninety  African giant land snails (A. marginata) of average body weight 160.31g ± 0.38g were used for the study. The snails were grouped into two- Group A and Group B. 45 snails in group A were raised in an intensive system of management while 45 snails in group B were raised in an extensive system of management. The data collected on weight gain, shell length increment and shell width increment during the experiment were subjected to student t-Test at 5% significant level. Results showed that there was a significant difference at (p<0.05) in the weight gain. The intensive management system had a higher weight gain of 128.96g with mean value of 4.96 while the extensive management system had a weight gain of 88.37g with mean value of 3.40. There was no significant difference at (p>0.05) in the shell length increment. The snails in the extensive management system had the higher shell length increment of 5.32cm with mean value of 0.20 while the snails in the intensive management system had a shell length increment of 2.43cm with mean value of 0.09. There was a significant difference at (p<0.05) in the shell width increment. The snails in the extensive management system had the higher shell width increment of 9.31cm with mean value of 0.36 while the snails in the intensive management system had a shell width increment of 4.30cm with mean value of 0.17. The snails in the intensive system had a Feed Conversion Ratio of 5.03. For better growth performance of A. marginata in terms of weight gain, snail farmers should raise their snails in an intensive system of management and formulated diet should be used in feeding the snails along side with natural feed such as leaves and fruits.
Induction of genotoxicity after subchronic treatment with 4-nonylphenol in blood cells from gill and kidney and restoration of DNA integrity after recovery by Channa punctatus
Authors: Sharma Madhu , Chadha Pooja
Published: June 2019

The aim of present study was to assess the genotoxic effects of endocrine-disrupting compounds 4-nonylphenol (NP) on Channa punctatus after sub chronic exposure. Blood cells from gill and kidney were used for the study and micronucleated cell (MNC) and aberrant cell (AC) frequencies were used as biological indicators. The exposure was given to C. punctatus for 90 days, and the effect was seen after 30, 60, and 90 days of exposure. Three sublethal concentrations were decided after calculating the safe application rate. Exposure resulted in increased frequency of MNC and AC in both the tissues. Gill tissue was found to be more sensitive to 4-nonylphenol exposure. Highest MNC and AC frequency was found at 90 days of exposure in gill tissue and the values were 4.45±0.28 and 63.71±0.84 respectively. After exposure for 90 days, post-30 days recovery was also studied and we found a significant reduction (p?0.01) in the values of both the parameters showing a great capacity of C. punctatus to restore its DNA integrity.

Karet merupakan hasil pertanian[1-10] yang penting bagi kehidupan manusia. Indonesia merupakan salah satu negara yang menghasilkan komuditas karet terbesar di-dunia setelah Negara Thailand dan juga Malaysia yang juga penyumbang karet di kancah Internasional. Indonesia memiliki luas perkebunan karet kurang lebih 2,7-3 hektar yang tersebar di penjuru Nusantara. Karet merupakan hasil tani utama yang mampu menyokong perekenomian negara hingga tahun 1992, akan tetapi luasnya kebun karet di Indonesia berbanding terbalik dengan mutu karet yang dihasilkan.Karet yang dihasilkan di Indonesia memiliki produktivitas mutu yang rendah dikarenakan tidak tersedianya koagulan yang baik dikalangan petani. Hal ini menyebabkan mutu karet dari Indonesia masih kalah dipasar Internasional oleh Thailand dan Malaysia. Adapun tujuan dari penelitian ini adalah untuk mengetahui beberapa koagulan yang baik digunakan untuk menghasilkan karet bermutu serta memiliki daya saing dengan negara-negara penghasil karet diseluruh dunia.

Human Capital Accountability and Construct: Evidence from Islamic Microfinance Institutions in Malaysia
Authors: Kamaluddin Amrizah , Kassim Nawal , Alam Md. Mahmudul , Abu Samah Siti Akmar
Published: June 2019

To identify the human capital construct that significantly relates to the performance of Islamic organizations, this study obtained data from Islamic microfinance organizations in Malaysia using the survey questionnaire method. In addition, we interviewed renowned scholars in the fields of Islamic accounting and Shariah law. Consequently, this study proposes an extended model of human capital that is applicable to Islamic organizations. Apart from knowledge and competency, this study includes spiritual value as another construct of human capital in Islamic organizations. Knowledge includes ideas that are relevant to the accounting and auditing spectra, as well as Shariah principles and jurisprudence. By contrast, competency refers to the ability to innovate unique Shariah-compliant products that are rare and difficult to imitate. Meanwhile, spiritual values embrace the elements of “Siddiq,” “Amanah,” “Fathonah,” and “Tabligh.” This study affirms that knowledge, competency, and satisfaction are the most significant constructs of human capital that explain performance. Factor analysis indicates that spiritual value is embedded in and forms part of the human capital construct. Hence, spiritual value is a key element in company culture and contributes significantly to organizational success. This model can be a platform for human capital reporting in the relevant Islamic and conventional organizations.

HD 163296 is one of the few protoplanetary discs displaying rings in the dust component. The present work uses ALMA observations of the 0.9 mmcontinuum emission, which have significantly better spatial resolution (~8 au) than previously available, to provide new insight into the morphology of the dust disc and its double ring structure. The disc is shown to be thin, and its position angle and inclination with respect to the sky plane are accurately measured as are the locations and shapes that characterise the observed ring-gap structure. Significant modulation of the intensity of the outer ring emission is revealed and discussed. In addition, earlier ALMA observations of the emission of three molecular lines, CO(2-1), C18O(2-1), and DCO+(3-2) with a resolution of ~70 au are used to demonstrate the Keplerian motion of the gas, which is found to be consistent with a central mass of 2.3 solar masses. An upper limit of ~9% of the rotation velocity is placed on the in-fall velocity. The beam size is shown to give the dominant contribution to the line widths, accounting for both their absolute values and their dependence on the distance to the central star.

In this study, CuO-doped material fabricated from rice husk ash and red mud was modified by CeO2 promoter and urea using the impregnation method. The obtained samples were investigated for catalytic degradation of aromatic derivatives (benzene,toluene, and p-xylene - BTX) at a temperature range of 275 to 450oC. This demonstrated that all samples were highly active in the BTX treatment. Several techniques, such as X-ray powder diffraction analysis (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), BET surface areas and pore parameters (N2physisorption), and hydrogen temperature programed reduction (H2-TPR), were applied to analyse properties of obtained materials. The modification of CuO-doped catalytic material by both CeO2 promoter and urea resulted in decreased particle size, increased CuO dispersion, and improved catalytic activity of the material. In relation to this material, the conversions of benzene, toluene, and p-xylene were 66.1%, 96.8%, and 96.8% respectively at 375oC.

Aquaculture is an important economic activity in the coastal zone of Vietnam. Thanh Phu is one the coastal districts in Ben Tre province that rears brackish aquaculture. In recent years, farmers could not grow shrimp because of salinity intrusion and market price fluctuation. This study aims to determine aquaculture and fallow aquaculture pond distribution by using the three indices of NDVI (Normalized Difference Vegetation Index), MNDWI (Modified Normalized Difference Water Index) and NDBaI (Modified Difference Bareness Index) on Landsat 8 imagery. The results reveal that remote sensing can support the detection of aquaculture and fallow ponds with a high accuracy of 77%. The total aquaculture area is approximately 13,093.65 ha, of which the total fallow area is 581.49 ha (roughly 4.44% of the total aquaculture area). Moreover, the fallow ponds are randomly distributed in all four ecological zones and mostly in the fourth ecological region (about 73.92%). In the fourth region, saline concentration in water is from 20 to 30‰, which directly influences cultured shrimp farms. The results also indicate the spatial distribution of aquaculture ponds and ineffective aquaculture locations using Landsat 8 imagery via index image analysis. The findings support the local management’s decision making on further aquaculture planning.

During the past decades, near-infrared (NIR) methods have been applied to many aspects of life, particularly in dentistry. X-ray methods involve reliable techniques that dentists use to evaluate tooth structure lesions. However, X-ray methods still have some limitations, such as affecting patient health and dentists. In addition, early demineralised enamel is barely detected by X-ray methods. Many studies have demonstrated the usefulness of NIR light for observing tooth structure due to the differences of the optical properties between sound and demineralised tooth tissues under NIR wavelengths. Early demineralisation located under the enamel layer can be observed by NIR imaging (780-1,300 nm). The areas suspected to be demineralised enamel are distinct from the stain and pigmentation because stain and pigmentation do not appear in NIR images. The demineralised areas are substantially darker than the surrounding sound tissues under NIR light. In this study, two optical systems with transillumination and scattering techniques using NIR light (940 nm) were built for capturing occlusal and approximal images of teeth. The systems fulfill some requirements, such as simple setup, safety, and affordable price for the purpose of the replacement of imported equipment.

Fusarium proliferatum has been identified as the causal pathogen of Fusarium root rot of Ba kich (Morinda officinalis) (FRRBK). No studies are available regarding the effectiveness of chemical treatments on the disease incidence of FRRBK. The efficacy of five active ingredients (metconazole, prochloraz, tebuconazole, kresoxim-methyl, and pyraclostrobin) from two chemical groups (demethylation inhibitors and quinone outside inhibitors) in reducing three isolates (BKVN, BKDT, and BKPL) of F. proliferatum mycelial growth was tested in vitro. The results indicate that only metconazole, prochloraz, and tebuconazole are highly effective in inhibiting the mycelial growth of F. proliferatum. These were selected for investigation of their efficacy with regard to the disease incidence of FRRBK in pot and in field conditions. Prochloraz and metconazole showed the highest efficacy and significantly suppressed the disease incidence of FRRBK in pot and in field conditions.

Published: June 2019

Background: the role of malnutrition, inflammation, atherosclerosis, and particularly the combination of these three factors were closely related to cardiovascular events, hospitalisation frequency, and death in end-stage renal disease (ESRD) patients. This study examines the relationship between malnutrition-inflammation-atherosclerosis (MIA) syndrome and mortality among these patients during an 18-month period.Subjects and methods: in this prospective observational cohort study, all cause-mortalitywas evaluated during an 18-month follow-up period. A total of 174 patients with ESRD (including 57 non-dialysis patients, 56 peritoneal dialysis patients, and 61 hemodialysis patients) were enrolled. M (malnutrition) was assessed by the seven-point subjective global assessment (SGA), serum albumin. I (inflammation) was assessed by serum hs-CRP, serum IL-6. A (atherosclerosis) was defined asIMT ≥0.9 mm or the presence of plaque in the carotid artery. The patients are classified into four groups by number of components (MIA0, MIA1, MIA2, MIA3). Results: 73.6% of patients had at least one component of MIA syndrome. The proportion of patients with malnutrition, inflammation, and atherosclerosis accounted for 36.8%, 21.3%, and 50.6%, respectively. The proportion of patients with 3, 2, 1 component accounted for 4.0, 27.0, and 42.5%. There was no difference between MIA groups based on age, sex, percentage suffering from dyslipidemia, anemia, or Hb levels. Relative to patients experiencing no elements of MIA syndrome, patients with three components experienced a 13.16 times higher risk of mortality. Only malnutrition was a strong predictor of mortality with HR (95% CI): 5.90 (2.46-14.14).Conclusion: clinical physicians should attend more closely to and provideearly assessments ofMIA syndrome in patients with ESRD. They should care for nutrition conditions and thereby provide early and effective treatments. This can contribute to enhancements in quality of life, and decrease mortalityrates inpatients.

Authors:   Pham Ngoc Thach University of Medicine, Thieu Ha Van
Published: June 2019

Background: childhood overweight is increasingly common worldwide as are its consequences, which include increased risk of later cardiovascular disease and diabetes. Although metabolic syndrome (MetS) has been extensively studied in adults, not much is known about the condition in children and adolescents. MetS and its individual components are detectable during childhood, and both commonly persist throughout adolescence and adulthood.Objective: to determine the prevalence of MetS and cut-off values of waist circumference (WC) and body mass index (BMI) for predicting MetS in children with overweight and obesity. Methods: we conducted cross-sectional analysis of 510 children with overweight and obesity aged 10 to 15 years in Bien Hoa city, Dong Nai province (2012-2014). MetS diagnosis was defined according to the 2007 International Diabetes Federation definition. Results: a relationship existed between BMI and dyslipidaemia (p<0.05). Among all participants, 31.37% met the criteria for MetS (female>male, p>0.05). The most common manifestation of MetS in this study was WC-blood pressure-triglyceride (41.15%). The cut-off anthropometry values for predicting MetS were as follows: BMI of 25.00 in boys and 24.50 in girls, and WC of 82 cm in boys and 80 cm in girls. Conclusions: the prevalence of MetS was 31.37% among children with overweight and obesity. The cut-off values of WC and BMI in this study could be the optimal threshold for predicting MetS in such children aged 10 to 15 years.

This study aims to develop a method for calculating the carbon footprint of rice during its life cycle by combining Life Cycle Assessment (LCA) and the 2006 Guideline of the Intergovernmental Panel on Climate Change (IPCC) for National Greenhouse Gas Inventories (GL 2006) for paddy rice grown in Phu Luong commune, Dong Hung district, Thai Binh province, Vietnam. In the course of the study, a LCA survey that included activities in the upstream processes, the agricultural process, and the post-farm stage was conducted based on interviews with three groups of 30 farmer households that apply the conventional practice of rice production, the system of rice intensification (SRI), or the wide-narrow row method. These cultivation practices are applied for both the winter-spring crop and summer-autumn crop seasons. The emissions were calculated by multiplying the activity data by the default emission factors in GL 2006 or in other relevant studies. The emission factors of methane (CH4) from rice cultivation and nitrous oxide (N2O) from agricultural soil were adjusted using actual measurement results from the Institute of Agricultural Environment (IAE) in 2016. The results of the calculations show that the main sources of the emissions that constitute the carbon footprint of rice include: (i) CH4 emissions from rice cultivation; (ii) electricity generation for irrigation; (iii) diesel combustion for the operation of agricultural machinery, and (iv) fertiliser production. Emissions from other activities were negligible. The carbon footprint of spring rice is 2.69kgCO2e/kg of rice grown using the conventional paddy cultivation method, 2.35 kgCO2e/kg for rice grown using the SRI method, and 2.29 kgCO2e/kg for rice grown using the wide-narrow row method. In summer, the carbon footprint for rice grown using the conventional method is 3.72kgCO2e/kg of rice, 3.56 kgCO2e/kg of rice using SRI, and 3.3kgCO2e/kg of rice using the wide-narrow row method. Three mitigation options are proposed: integrated crop management for rice; alternate wetting and drying; and the substitution of urea fertiliser (CO(NH2)2) with ammonium sulphate ((NH4)2SO4).
ASPEK PAJAK PENGHASILAN FINAL PADA SEKTOR USAHA MIKRO KECIL DAN MENENGAH (STUDI KASUS PT PCT TANGERANG)

AbstractIndonesia cut the final income tax rate for small and medium-sized enterprises by half, to 0.5 percent of their annual sales, in a move to help businesses manage their cash flow and expansion. While the current arrangement only demands simple accounting, small and medium-sized enterprises say it also means they have to pay income tax when they are at loss, which disrupts their cash flow(Jakarta Globes, 2018). The Government has shown its strong support for the development of small and medium enterprises (SMEs). After improving the tax facility for venture capital companies who invest in SMEs, the Government has now issued Government Regulation (GR) No.23/2018 (GR-23) which stipulates a new “final tax”rate for SMEs. GR-23 will enter into force on 1 July 2018 and revokes GR No.46/2013 regarding final tax on taxpayers within a certain turnover. The final tax regime, introduced in GR-46, is applicable for taxpay ers with annual gross turnover of not more than IDR 4.8 billion (approximately USD 340 thousand), excluding the following income: a.fees from the delivery of certain freelance services by individuals; b. overseas income which has been taxed in the source country; c. income also subject to final tax; and d. non - taxable income. The threshold of IDR 4.8 billion per annum is based on the previous years’ activity, including gross turnover sourced from branches. If during a fiscal year the gross turnover exceeds IDR 4.8 billion, the taxpayer remains subject to final tax for the current year but must adopt the “ normal tax ” rate (Article 17 or Article 31E Income Tax) for the following year. While the provisions on gross turnover generally remain unchanged, GR – 23 now reduces the final tax rate to 0.5% from the previous 1%.Key words : Final Income Tax ,  Micro, Small and Medium Enterprises.

Emotional intelligence (EI) is the recognition and management of emotions. This skill set is important to work relationships and professional success. In this cross-sectional, observational study, we investigated EI scores of 4th-year veterinary students, interns, and residents in a teaching hospital, using a psychometric tool with professional population norms. Participants’ EI scores were compared with professional norms and between the sample groups. Scores were examined on the basis of demographics and residency program type. Twenty-four 4th-year students and 43 interns and residents completed the survey. Total, composite, and subscale scores for all groups were lower than professional means. We noted no statistically significant differences in EI scores between training levels, but evaluation of effect sizes showed a medium negative effect of higher training levels on Self-Perception Composite, Self-Regard, Emotional Expression, Interpersonal Composite, Flexibility, and Optimism and a medium positive effect of higher training levels on Impulse Control. Medium effects for residency type were found for Stress Tolerance, Flexibility, and Stress Management, with higher scores for residencies with heavy inpatient loads. Medium effects for residency type were found on Flexibility scores, with higher scores for residents in disciplines with a perceived high stress level. We found that baseline EI scores of 4th-year veterinary students, interns, and residents at a teaching hospital were similar to, but uniformly lower than, those of other professionals and did not increase with training level. These results may be used to build on strengths and address weaknesses associated with EI of students and house officers at this institution.
Assessing Disaster Preparedness and Educational Needs of Private Veterinary Practitioners in Mississippi
Authors: Huston Carla L. , Ebers Kathleen L.
Published: June 2019

The veterinary medical education system faces increasing challenges in educating students in the most current technologies while responding to changing community needs and expectations. Communities expect veterinarians to be involved in disaster management at some level. The purpose of this study was to describe the level of disaster preparedness and educational needs of veterinary practitioners in Mississippi. A survey was mailed to 706 practitioners to assess disaster plans, disaster training, and familiarity with disaster-related organizations. Forty-three percent of veterinarians had a clinic disaster plan. Veterinary practitioners who had experienced a disaster were more likely to have a personal plan (odds ratio [ OR] = 4.55, 95% confidence interval [CI] = 2.47–8.37) and a clinic plan ( OR = 4.11, 95% CI = 2.28–7.44) than those who had not. Veterinarians residing in Mississippi Gulf Coast counties were more likely to have a personal plan ( OR = 3.62, 95% CI = 1.54–8.72) and a clinic plan ( OR = 3.09, 95% CI = 1.35–7.21) than were those residing in other areas. Only 17% of veterinarians had assistance agreements with other practices, and few veterinarians indicated having disaster education materials available for their clients. Twenty percent of respondents indicated having obtained formal disaster training, and more than two-thirds of respondents were interested in receiving disaster training, mostly in the form of online delivery. Results suggest that private veterinary practitioners have the desire and need to obtain disaster education. Providing opportunities for both veterinarians and veterinary students to obtain education in disaster management will result in better overall community disaster preparedness.
Piloting a Mindfulness-Based Intervention to Veterinary Students: Learning and Recommendations
Authors: Pontin Eleanor E. , Hanna Julie , Senior Avril
Published: June 2019

Veterinary students experience high levels of psychological distress including anxiety, stress, perceived stress and depression. The inability to cope with the demands of veterinary training has personal and professional consequences. Existing evidence shows that mindfulness-based interventions (MBI) can reduce stress in students, but more research on how MBIs are introduced into the veterinary curriculum is required. The first aim of the pilot study was to design and deliver a bespoke MBI to third-year veterinary students at the University of Liverpool Institute of Veterinary Science. The second aim was to gain feedback from those taking part, thus using their experiences to explore the challenges of introducing an MBI into a veterinary curriculum. By doing this, we aim to reflect and learn for future interventions. Qualitative feedback provided by participants of the MBI focus group was analyzed using thematic analysis and organized into two main themes: (1) “Taking Part in the MBI and Beyond—What it Was Like and What Has the MBI Done for Me?” and (2) “Mindfulness for Veterinary Students—Reflections, Challenges, and Making it Happen.” Experiences and outcomes of the MBI were positive. However, implementation into the veterinary curriculum was found to be challenging. This pilot study provides clear recommendations to support the future integration and delivery of MBIs into a veterinary curriculum.

Video- versus handout-based instructions may influence student outcomes during simulation training and competency-based assessments. Forty-five third-year veterinary students voluntarily participated in a simulation module on canine endotracheal intubation. A prospective, randomized, double-blinded study investigated the impact of video ( n = 23) versus handout ( n = 22) instructions on student confidence, anxiety, and task performance. Students self-scored their confidence and anxiety before and after the simulation. During the simulation laboratory, three raters independently evaluated student performance using a 20-item formal assessment tool with a 5-point global rating scale. No significant between- or within-group differences ( p > .05) were found for both confidence and anxiety scores. Video-based instructions were associated with significantly higher ( p < .05) total formal assessment scores compared with handout-based instructions. The video group had significantly higher scores than the handout group on 3 of the 20 individual skills (items) assessed: placement of tie to the adaptor–endotracheal tube complex ( p < .05), using the anesthetic machine ( p < .01), and pop-off valve management ( p < .001). Inter-rater reliability as assessed by Cronbach’s α (.92), and Kendall’s W (.89) was excellent and almost perfect, respectively. A two-faceted crossed-design generalizability analysis yielded G coefficients for both the handout ( Ep2 = .68) and the video ( Ep2 = .72) groups. Video instructions may be associated with higher performance scores than handout instructions during endotracheal intubation simulation training. Further research into skill retention and learning styles is warranted.
Integrating Individual Student Advising into Financial Education to Optimize Financial Literacy in Veterinary Students

The debt-to-income ratio (DIR) of Doctor of Veterinary Medicine (DVM) students has exceeded the recommended 1.4 and it is predicted that the DIR will approach 2.18 by 2026. The associated stressors negatively impact professional satisfaction and well-being. In conventional approaches to financial education, content is delivered to groups of students as part of the curriculum, but with little opportunity for application. Research in medical and financial education suggests that convenient timing, relevant subject matter and individualization are key characteristics of a successful program that promotes retention and application of knowledge. In this article, we describe an integrative approach to financial education developed by the Colorado State University (CSU) Financial Education Specialist (FES). The FES position requires that the individual be qualified to provide one-on-one financial advising to DVM students as well as develop targeted curricular interventions and optional workshops. Data from student and alumni surveys suggest that this integrative approach to financial education both improves knowledge and alters behaviors surrounding financial management. Interest from academic and professional entities across the United States reflects recognition of the program as an emerging best practice. We describe lessons learned through program implementation, including demands for FES services throughout the academic year, and topics relevant to each student cohort. We propose that providing one-on-one financial advice to DVM students is a critical component of a broader financial education program. Actualizing timing, relevance, and individualization, this integrated approach optimizes opportunities for knowledge application and ultimately behavioral change.
A Competency-Guided Veterinary Curriculum Review Process

Published: June 2019

Competencies can guide outcomes assessment in veterinary medical education by providing a core set of specific abilities expected of new veterinary graduates. A competency-guided evaluation of Colorado State University’s (CSU) equine veterinary curriculum was undertaken via an alumni survey. Published competencies for equine veterinary graduates were used to develop the survey, which was distributed to large animal alumni from CSU’s Doctor of Veterinary Medicine program. The results of the survey indicated areas for improvement, specifically in equine business, surgery, dentistry, and radiology. The desire for more hands-on experiences in their training was repeatedly mentioned by alumni, with the largest discrepancies between didactic knowledge and hands-on skills in the areas of business and equine surgery. Alumni surveys allow graduates to voice their perceived levels of preparation by the veterinary program and should be used to inform curriculum revisions. It is proposed that the definition and utilization of competencies in each phase of a curricular review process (outcomes assessment, curriculum mapping, and curricular modifications), in addition to faculty experience and internal review, is warranted.

In transportation technology, the development of electric vehicle is growing rapidly. In the future, the availability of electrical power is crucial because every electric tool needs electrical power. Power plant must provide electrical power for all consumer include an electric vehicle. Sustainability of electrical power transmission and distribution must be considered as critical due to its high power consumption in the community. One of the problem to supply electrical power is how to keep the system’s voltage stability. Several variations on the load pattern and topological can lead to a substantial poor impact on the system. However, generation cost must be considered by utilities’ operator. This paper demonstrates a recently developed metaheuristic method called Chaotic Firefly Algorithm (CFA). Our simulation shows that this method may perform better than several well-known metaheuristic methods. Therefore, CFA may become a promising method to solve optimal power flow considering voltage stability cases.
