Evaluation and Optimization of an Aqua-Ammonia Vapor-Absorption Refrigeration System
Abstract: The process parameters of ammonia-water absorption system were optimized in terms of temperatures of generator and condenser and heat ratios of generator-to-condenser and generator-to-absorber. The iteration method was used to get the variation in generator and condenser temperatures with coefficient of performance (COP) for the fixed evaporator temperature. The sizing of generator, absorber and condenser was found from the variation of heat ratios of generator-to-condenser and generator-to-absorber for the fixed …

Phytoremediation of Aquaculture Wastewater: Duckweed (Lemna minor L.) as a Phytoremediator
Abstract: Aquaculture systems discharge huge quantities of waste into the aquatic ecosystem, in the form of excretory products and excess feed. These have grave implications on physicochemical and biological quality of the receiving environment. The study aimed to determine potential of duckweed (Lemna minor L.) for phytoremediation of aquaculture effluent. Hundred grams (100 g) of duckweed was grown in 10 L aquaculture effluent for 7-, 14-, 21-, and 28-day retention period …

Effect of Nitrite on Oxygen Consumption and Ammonia Excretion of the Fresh Water Crab Paratelphusa jacquemontii (Rathbun)
Abstract: In aquatic ecosystem, nitrite concentrations are elevated by pollution with nitrogenous wastes and imbalances in bacterial nitrification and denitrification processes. Nitrite is transformed by nitrification to nitrate under aerobic condition. The effects of nitrite on physiology were investigated in the fresh water crab, Paratelphusa jacquemontii (carapace length 4–5 cm and weight 50–70 g) for 96 h. The crabs were exposed to sublethal concentration (1/10th and 1/20th of 96 h LC50) …

IoT Integration in Sustainable Agriculture
Abstract: The increasing demand for food production, environmental concerns, and resource limitations have necessitated the adoption of Internet of Things (IoT)-based innovative farming solutions. The current paper introduces an IoT-based system that integrates hydroponics, aquaponics, and poultry to promote sustainability, resource utilization, and agricultural productivity. Conventional farming practices are riddled with ineffective use of resources, uncertain environmental effects, and expensive operations. The new system facilitates real-time monitoring, automated decision support, and …

Application of Some Essential Bacterial Probiotics in Aquaculture: A Review
Abstract: Aquaculture plays an essential role in maintaining food security and sustainable lives for the world’s ever-growing population. Due to the expansion, intensification, and variety of aquaculture methods, aquatic animals confront significant challenges, including disease outbreaks, decreasing output, and risks to the sustainability of the sector. Poor soil conditions in aquaculture cause higher mortality, a higher prevalence of diseases, and lower yields of aquatic organisms. Overfeeding, dead animals, and feces from …

Design and Fabrication of Biofilter and Piping in Soilless Farming
Abstract: The most prevailing problems with the modern world are food and water Crises. It is neither possibleto consume the chemically contaminated food nor grow own plants, thanks to scarcity of water andland. Under such Conditions, there arises a requirement for portable agricultural system which Usesless water, space and is only organic. One such solution may be a small scale aquaponic system.Aquaponics uses fish waste to supply nutrients for plants, the …

Effect of different concentrations of mercuric iodide on the growth of Microcystis spp.
Abstract: Cyanobacteria are commonly called as blue green algae which are abundantly distributed in both aquatic and terrestrial ecosystem. They are procaryotic autotrophic organisms and have thallus structure. Such organisms are actively involved in the biological nitrogen fixation which can fix the atmospheric nitrogen and converts into ammonia compounds. Plants can utilize such converted components for their growth and metabolic activities. Since they are diazotrophs which is the suitable supplement to …

Impact of Mercuric Iodide on the Growth of Phormidium spp.
Abstract: Cyanobacteria are microalgae which are freely distributed in aquatic environment. They are photosynthetic organisms and can fix atmospheric nitrogen under anerobic condition. Such cyanobacteria have been applied as a nitrogen fertilizer in agriculture to improve the crop yield. Since the application of chemical fertilizers in crop fields created heavy metal pollution which could be neutralized by microalgae under aquatic environment. They have ability to tolerate the heavy metal concentrations under …

Water Hyacinth (Eichhornia crassipes) as Phytoremediator of Abattoir Contaminated Effluents
Abstract: The abattoir industry provided meat for more than 170 million Nigerians and job opportunities for teeming population. It has also been categorized as one of the industries responsible for major pollution of soil and water resources. The aim of this study was to analyze the pollutants present in the effluents from the selected abattoir and evaluate the effectiveness of water hyacinth (Eichhornia crassipes) in removing these pollutants. The experiment was …
