Considering the importance of filamentous fungi for bioremediation of wastewater and contaminated soils, this study was planned to investigate the metal tolerance potential of indigenous filamentous ...fungi. Nineteen fungal strains were isolated from soils irrigated with untreated municipal/industrial effluent using dilution technique and 10 prominent isolates were used for metal tolerance. The isolated fungal isolates were screened for metal tolerance index (MTI) at 1mM cadmium (Cd), nickel (Ni) and copper (Cu) concentrations and for minimum inhibitory concentration (MIC) and metal tolerance by growing on potato dextrose agar plates amended with varying amounts of Cd, Cu and Ni. Seven out of 10 isolated fungi belonged to the genera Aspergillus and three belonged to Curvularia, Acrimonium and Pithyum. The results revealed that the order of tolerance of isolates for metals was Cd greater than Cu greater than Ni and Aspergillus sp. were more tolerant than other fungi. Tolerance ranged from 900-9218 mg L-1 for Cd, followed by 381-1780 mg L-1 for Cu and 293-1580 mg L-1 for Ni. The isolated fungi exhibiting great tolerance to metals (Cd, Cu and Ni) can be used successfully for bioremediation of metals from contaminated soil and wastewaters.
Objective: The objective of this study is to explore the intergenerational transmission of cultural values within bicultural families, focusing on how these families preserve their cultural heritage, ...adapt to their host society, and navigate the associated challenges. Methods: This qualitative research employed semi-structured interviews with 21 participants from diverse bicultural backgrounds. Participants were selected using purposive sampling to ensure a variety of cultural perspectives. Data collection continued until theoretical saturation was reached. The interviews were transcribed and analyzed using NVivo software, following a thematic approach to identify patterns and themes related to cultural value transmission. Results: The analysis revealed three main themes: preservation of cultural practices, adaptation and integration, and challenges and negotiations. Cultural preservation was achieved through traditional ceremonies, language use, cuisine, arts and crafts, and dress. Adaptation involved blending cultures, educational influences, social interactions, and media use. Challenges included generational conflicts, identity issues, discrimination, acculturation stress, balancing preservation with change, and economic factors. These findings align with existing literature on biculturalism and cultural transmission. Conclusion: The study highlights the complex dynamics of cultural value transmission in bicultural families, emphasizing the importance of supportive societal structures and policies. The findings suggest that family therapists, educators, and policymakers should consider these dynamics to effectively support bicultural families in maintaining their cultural heritage while adapting to their host society. Future research should expand on these findings by exploring additional variables and employing longitudinal designs.
Proteins may form undesirable aggregates during the process of folding. Increasing evidence suggests that amyloid fibrils may arise from partially folded precursor molecules. We have previously ...demonstrated that hen egg white lysozyme HEWL exists as molten globule at pH 12.7. Here, we report that lysozyme at pH 7.0 and 11.0 are nearly stable to the addition of up to 45% t-butanol, but treatment of the alkali-induced molten globule form of HEWL AMGL with 20% t-butanol caused the formation of amyloid-like fibrils as evidenced by enhanced Thioflavin T binding and DLS measurements.
Role of Renewable Energy Resources (RES) is increasing day by day due to continuously depleting fossil fuels. Moreover, to make environment-friendly power generation, RES is one of the best options. ...According to the International Renewable Energy Agency (IRENA), the number of countries which aim their grids synchronized with RES has reached 180. This increasing trend of RES integration is causing new vulnerabilities in power system. This paper studies the impact of an increase in load under the different percentage levels of wind generation. Six cases are discussed, each with 10% increase in wind penetration along with 5% increase in load at every step. Modified IEEE-14 bus system is analyzed under various scenarios to evaluate the minimum voltage level, minimum angle, active and reactive power loss in the power system. Mat-Power and MATLAB are used to evaluate the power system. Results show that 20-30% wind generation penetration has a good impact on power system's performance. However, further increase in wind generation results in more power losses.
In the "friends and family test," 97% of patients recommend us. 2 We were in the top 20% of hospitals for patients rating our care "good" or "excellent" (94% did) in the national cancer patients ...survey. 3 We have met the 18 week waiting time target for the past two years and consistently hit the main cancer and diagnostic waiting times. 3 Our emergency department performance was among the best in the country last year, and above average this year (NHS England and trust data).
Industrial sector is of great significance for economic growth of every country, but industries are polluting our environment day by day. Most of the customers at industrial and commercial level use ...Diesel Generator (DiG) as a reliable alternative source of electrical power when grid supply is unavailable. The use of DiG during loading shedding hours would increase Cost of Energy (COE) per KWh and also enhance the environmental emissions. With the distinct emphasis on the implementation of an industrial microgrid in Faisalabad, Pakistan has been specified in this paper. The prospective benefits of the microgrid fall into three major kinds: cost reduction, fuel saving, and improved environmental emissions. The optimization objective of this work is to maximize these benefits. This study contributes to the on-going studies about hybrid microgrid system for industrial loads and draws the attention towards clean form of energy to reduce the environmental emissions and energy saving. Different cases are studied; microgrid sizing, techno-economic exploration and environmental effects are addressed using (Hybrid Optimization Model for Electric Renewables) HOMER. The results show that COE and environmental emissions have been significantly reduced for the proposed system.
