The document discusses optimizing water use efficiency in C4 crops. It provides background on C4 photosynthesis being more efficient than C3 with better water use efficiency. The researcher aims to determine if there are differences in water use efficiency across C4 plant species and if those differences can be used to reduce strain on water resources from agriculture. Methods used include LI-COR photosynthesis measurements and comparative genomics and phenomics on species like sorghum, maize, and dichanthelium. Future steps involve relating water use efficiency data from imaging and LI-COR measurements.
Development of integrated bioremediation and anaerobic digestion process usingIAEME Publication
This document discusses a study on the development of an integrated bioremediation and anaerobic digestion process using microalgae. Specifically, it examines using the microalgae Chlorella pyrenoidosa to treat biogas digester wastewater. The study finds that C. pyrenoidosa is able to grow well in biogas wastewater, removing up to 92.8% of nitrate nitrogen. The treated wastewater can then be used to support anaerobic digestion of the algal biomass to produce biogas. Co-digesting the microalgae with cow dung achieved higher biogas yields than digesting cow dung alone. Overall, the integrated process effectively treats biogas

Effect of Magnetic Treatment of Water on Evapotranspiration of TomatoAZOJETE UNIMAID
This document discusses a study on the effect of magnetic treatment of water on evapotranspiration of tomato plants. Three magnetic flux densities were used to treat water for tomato irrigation, along with a control of non-treated water. The amount of water lost daily from buckets containing tomato plants due to evapotranspiration was measured. Plants irrigated with magnetically treated water had higher daily evapotranspiration rates compared to the control, indicating treated water allowed easier water absorption and faster plant growth despite equal water quantities.
This document provides an overview of a research project studying the effects of different grazing management strategies on carbon and nitrogen cycling in rangelands. The project compares a low stocking density grazing strategy to an ultra-high stocking density strategy. Key findings include greater vegetation trampling but similar litter deposition under high density grazing. The project also found higher dung beetle diversity under rotational grazing regardless of stocking density. Dung beetle activity did not significantly impact greenhouse gas fluxes or dung decomposition rates. Spatial and temporal patterns of dung distribution will be modeled to estimate ranch-level nutrient cycling under different management strategies.
This document discusses the potential for third generation algae biofuels to displace fossil fuel use and reduce greenhouse gas emissions. It finds that algae biofuels have significant advantages over fossil fuels, including much higher oil yields per acre and lower carbon dioxide emissions. However, large-scale production of algae biofuels faces challenges, particularly the need for large amounts of water and the currently high energy inputs required. While algae biofuels show promise, further technological advances are still needed to improve their economic viability and environmental sustainability compared to fossil fuels.

This document discusses using bioprocess technology to produce sustainable biofuels from large-scale algal culture. Specifically, it experimentally proves that combining plug flow reactors with airlift fermenters on a large scale can sustainably generate biofuels by harvesting light with algae. This process allows for continuous fermentation, biomass separation with only sparging required, and generates algal biomass in self-sustaining airlift fermenters. Algae are also efficient producers of oil and biomass and have higher photosynthetic efficiency and growth rates than plants. The document concludes that microalgae have much higher biofuel yields than other feedstocks and can use non-arable land, making them a promising
Biomass and the Environment: Soil and Water ImpactsAmanda Bilek
Presented by David Mulla, Professor and Larson Chair for Soil & Water Resources, University of Minnesota on December 8, 2014 at the Minnesota Bioenergy Feedstock Development meeting and forum.
This document summarizes a study examining the impact of different fertilizer application rates on nitrous oxide (N2O) emissions and nitrogen losses from plantain crops in Puerto Rico. The study involves measuring N2O fluxes, soil nutrients, plant growth, and yields from a control and 3 treatments - a slow release fertilizer, the local agricultural university's recommended rate, and no additional nitrogen. Preliminary results show significantly reduced N2O emissions from the lower nitrogen rates, though yields were similar across treatments. The results will be used to calibrate a modeling tool to estimate potential nutrient and greenhouse gas reductions across Puerto Rico and identify areas for greatest impact. The long term goals are to develop best practices to reduce emissions and establish an
This study found that shade trees increased the light use efficiency (LUE) of coffee plants by 57% despite decreasing available photosynthetically active radiation (aPAR) by 41%. The 3D light and gas exchange model MAESPA found that the increased LUE under shade trees could only be partially explained by the increase in diffuse light, with changes to microclimate also playing a role. Surprisingly, the net primary productivity of coffee resprouts did not differ between light environments, suggesting a nearly total compensation of productivity despite large reductions in aPAR under shade trees. This level of compensation is rarely observed in other studies but may be possible due to coffee's natural shade tolerance.
This document summarizes a presentation given at the UK AD and Biogas conference on maximizing the fertilizer value of anaerobic digestate. The presentation discusses the typical nutrient content of food-based digestate and livestock slurries. It also discusses techniques to maximize nutrient use efficiency such as applying digestate in spring to minimize nitrate leaching, using band spreading or shallow injection to reduce ammonia loss and ensure even application. The presentation recommends knowing the nutrient content of the digestate through lab analysis, applying it accurately and evenly using precision machinery, and integrating it into farm nutrient management plans to reduce the need for bagged fertilizers.
This project worked with small farmers in Florida to reduce water quality degradation from farm runoff. The project exposed farmers to techniques like efficient compost/manure use, improved irrigation, and solar power systems. Soil and water tests showed that at one site, practices increased organic matter and adjusted nutrient levels, while a flooded site had increased hardness, calcium, and sodium. The project provided training, demonstrations, and consultations to farmers, with most upgrading irrigation systems and some adopting conservation practices. Ongoing challenges include excessive manure use and high solar costs.

A Solution to Profitable Agriculture Practices & Reclamation of Saline Land For Food Security
The document presents the results of a life cycle assessment comparing the environmental impacts of water quality from non-potable water reuse and energy recovery using anaerobic and aerobic treatment trains. It finds that a mainstream anaerobic process has the potential to be more sustainable than conventional aerobic treatment, especially when optimized for maximum biogas recovery and minimum energy consumption. Further experimental work is recommended to better realize the environmental benefits of anaerobic nutrient removal technologies.
Magnetic water treatment is a technology that uses magnets to alter the structure of water without changing its chemistry. It works by applying a magnetic field to water, which exerts a Lorentz force on ions and increases collisions between ions. This causes water molecules to cluster into smaller, more "bio-friendly" formations that can prevent scale buildup and increase nutrient absorption in plants. Studies have shown magnetic water treatment can increase crop yields by 10-30%, reduce water and fertilizer use, and improve soil health. Case studies on wheat, peas, and amaranth found magnetized irrigation water significantly increased plant growth rates and nutrient content compared to non-magnetized water.

The potential of microalgae meals in compound feeds for aquacultureInternational Aquafeed
Intensive production of mainly carnivorous fish has resulted in fish feeds containing high levels of fishmeal and fish oil, with Europe requiring around 1.9 million tonnes a year. Although this use of fishmeal was initially the recycling of waste from fishing through the use of bycatch and trimmings, due to the rapid development of aquaculture this reliance on fishmeal and fish oil is environmentally unsustainable. This has resulted in other sources of fish feed being investigated. This literature review will focus on microalgae; the composition in terms of nutritional quality, the current methods of production and associated costs along with potential future uses such as feed in aquaculture.
Protect Environment In Aquaculture Production2 BaoRidzaludin
The document discusses environmental issues caused by aquaculture development in Vietnam and measures to address them. Rapid expansion of aquaculture has led to forest destruction, water quality changes, and decreased biodiversity. This negatively impacts both the environment and aquaculture production. Proposed measures include mangrove reforestation, proper zoning of aquaculture, wastewater treatment, limiting chemical and antibiotic use, water quality monitoring, and raising awareness of farmers.
This presentation provides an overview of microalgae culture techniques. It discusses that microalgae are the base of the marine food chain and are commonly used in commercial aquaculture operations. It then describes the major classes of cultured algal species and summarizes different culture methods including batch, continuous, indoor and outdoor techniques.

IRJET- Enhancement of Biogas Production by Co-Digestion of Fruit and Vegetabl...IRJET Journal
This document discusses a study on enhancing biogas production through co-digestion of fruit and vegetable waste with cow dung. Four mixtures of fruit, vegetable, and cow waste were prepared in different ratios and subjected to anaerobic digestion. The biogas production from each mixture was measured and modeled using logistic and modified Gompertz kinetic models. The results showed that a ratio of 0.5 parts fruit waste, 1.5 parts vegetable waste, and 1 part cow waste produced the highest amount of biogas and fit best to the modified Gompertz model. Characterization of the waste mixtures found total solid and volatile solid contents ranged from 74-75% with C/N ratios between 5-9.
Systematic analysis of algalbio-fuel production integrated with domestic wastewater treatment in Armenia. The document discusses using algae grown in wastewater to produce biofuels, reducing emissions while treating wastewater. It evaluates using traditional wastewater ponds, advanced integrated ponds, or photobioreactors with wastewater. Algae grown would be harvested and processed to extract oils for biodiesel production. Future work could focus on decentralized, movable photobioreactor systems for flexible wastewater treatment and biodiesel production.
This document discusses demands on biogas plants, including demands related to logistics, physical properties of substrates, and biochemical qualities of substrates. It notes that biogas production requires continuous availability of substrates. Substrates must meet demands regarding solid content, temperature, and viscosity for efficient microbial activity. Substrates also must provide suitable conditions for different microorganisms involved in hydrolysis, acidogenesis, acetogenesis, and methanogenesis stages. The use of digestate as fertilizer poses demands around nutrient supply and contaminant loads.

1. The document discusses pretreatment of Prosopis Juliflora stem using ionic liquids to produce bioethanol in Kenya.
2. It analyzed pretreatment using three ionic liquids - [BMIM]Cl, [4MBP]Cl, and [P66614]Cl. Pretreatment increased glucose yield up to 18 times compared to untreated biomass.
3. [BMIM]Cl and [4MBP]Cl performed better than [P66614]Cl, yielding maximum glucose of 73.27% and 61.63% respectively after pretreatment. This indicates Prosopis Juliflora's potential as a non-food biomass for bioethanol production in Kenya
This document discusses the ecological footprint of livestock production and methods for assessing the environmental impacts of different food production systems through life cycle assessment (LCA). It provides examples of using LCA to compare the greenhouse gas emissions of producing different animal products like pork, chicken and eggs. It also discusses using LCA and data envelopment analysis to benchmark dairy farms and identify opportunities to reduce environmental impacts and increase economic efficiency.
This document summarizes a study on the effects of biochar amendment on soil microbial communities, greenhouse gas fluxes, and crop yields. Random matrix theory-based network analysis revealed that biochar treatment resulted in a more complex and resilient microbial community network compared to the no biochar treatment. Crop yields tended to increase for the Napier biograss but not for corn. Greenhouse gas flux data and further microbial analyses are still underway. The long term goals are to improve agricultural sustainability through biochar amendment and understand the underlying microbial processes influencing greenhouse gas emissions and carbon sequestration.
This document reviews the effects of environmental factors and nutrient availability on the biochemical composition of algae for biofuels production. It discusses how temperature, light, pH, carbon, nitrogen, phosphorus, potassium, and trace metals can affect algal growth rates and the partitioning of carbon into lipids and carbohydrates. Understanding these interactions is important for developing sustainable high-productivity algal biofuel systems. While algae have potential for high oil yields, commercial production of algal biofuels has faced challenges. The review examines how environmental conditions influence algal metabolism and composition in both natural and engineered systems.
This document summarizes a study that cultivated the microalgae Chlorella vulgaris in liquor from chemically treated sewage sludge to produce biomass for anaerobic digestion and energy generation. Four types of sludge liquor media were tested: a control with polyelectrolyte (sample 1), two with different lime concentrations (samples 2 and 3), and one with ferric chloride (sample 4). C. vulgaris grew best in sample 1 liquor, producing 1.36 kg/m3 of biomass and providing the highest estimated energy generation of 3.07 kWh and economic value of £1.12 per cubic meter after anaerobic digestion. Samples 2 and 3 performed similarly while sample 4 supported
IRJET- Biogas Production from Municipal Solid Waste:- A ReviewIRJET Journal
This document reviews biogas production from municipal solid waste via anaerobic digestion. It discusses key factors that affect biogas production such as temperature, pH, carbon-nitrogen ratio, total solids and volatile solids. The document reviews several past studies on biogas production from waste materials like cattle manure, fruit and vegetable waste, and municipal waste. It finds that biogas yield varies significantly depending on factors like feedstock used and digestion conditions. The maximum reported methane yield was 404 ml/g VS from wheat plant waste, while the minimum was 0.40 Nm3/kgVS from waste in Varanasi, India. Further optimization of digestion systems is needed to improve biogas production efficiency from municipal solid waste
Micro - algae cultivation for biofuels: cost, energy balance, environmental i...Alejandro Roldan
Micro-algae have potential as a feedstock for biofuels but their economic viability and environmental sustainability depends on the energy and carbon balance, environmental impacts, and production costs. Most studies find that achieving a positive energy balance requires technological advances, and aspects like pumping energy, construction materials, fertilizer, and drying require further optimization. Environmental impacts from water, carbon dioxide, and nutrients could constrain design options. Cost estimates need better empirical data from commercial-scale production systems designed for biofuels. Significant cost reductions may only be possible if carbon, nutrients, and water are very low-cost, which is very demanding.

Systematic analysis of algalbio-fuel production integrated with domestic wastewater treatment in Armenia. The presentation evaluates using algae to treat wastewater and produce biofuels. It discusses using algae cultivation technologies like open ponds and photobioreactors, and the processes of algae harvesting, oil extraction, and biodiesel production. Future work could involve using photo bioreactors for decentralized wastewater treatment and biodiesel production. In conclusion, algae is a potential solution that can make wastewater treatment cost-competitive while producing biofuels to reduce carbon emissions.
There are significant biological, chemical, and mechanical engineering challenges to the commercialization of algae energy. Some of the key challenges include strain selection, maximizing photosynthetic efficiency, increasing lipid production, devising efficient fermentation processes, reducing the costs of harvesting, drying, and extracting oil from algae, and scaling up cultivation, harvesting, and processing systems in a cost-effective manner. Overcoming these challenges will be necessary for algae energy to become economically viable.
Utilization of Food Waste to Produce BiodieselIRJET Journal
This document discusses utilizing food waste to produce biodiesel. Food waste was collected from a university campus and analyzed. It had moisture contents ranging from 5.2-7.2% depending on drying method. Lipid extraction yielded 15.8% lipids. Gas chromatography identified various fatty acids present including lauric, mystric, palmitic, stearic and oleic acids, indicating potential for biodiesel production. Transesterification of the lipids produced 31.9% biodiesel. Testing found the biodiesel met various standards for density, viscosity and other properties, suggesting food waste is a viable feedstock for biodiesel production.

This study evaluated the life cycle assessment of organically grown cotton from cultivation to disposal. Key findings include that field emissions significantly contributed to environmental impact categories like eutrophication and acidification. Fertilizer production was also an important contributor to impacts. Compared to conventional cotton, organic cotton showed potential savings of 46% for global warming potential, 70% for acidification potential, 26% for eutrophication, 91% for blue water consumption, and 62% for non-renewable energy demand. These reductions were largely due to avoiding mineral fertilizers and pesticides in organic systems.
Biogas Production Enhancement from Mixed Animal Wastes at Mesophilic Anaerobi...IJERA Editor
In this work, the effect of mixing ratio of cattle dung (CD) and poultry droppings (PD) on biogas generation was
determined. Mixtures of various CD: PD ratios (100% : 0%; 50% : 50%; 60% : 40%; 80% : 20% and 0% :
100%) were prepared, analyzed and then aerobically digested for a period of 40 days. For each mixture,
fermentation was carried out in a 20 L capacity digester. Results showed that biogas was obtained from the
digestion of CD and PD alone, showing the biogas from CD was several times larger than that from PD.
Furthermore, the resulted biogas yields from mixtures were found a function of the CD : PD ratio, the yield from
the ratio 80 : 20 was the maximum. Biogas yields from the prepared mixtures were found and arranged from
larger to lower in the form of (CD : PD) ratios as follow: 80% : 20%; 100% : 0.0%; 60% : 40%; 0.0% :
100%;50% : 50%. Addition of CD to PD enhances the PD production of biogas, while addition of a small
portion of PD to CD gave the maximum yield, a result not determined in literature. In other hand, larger
additions of PD to CD reduced the biogas yield. The effect of pH was also determined and found better around
7.0. These results are in agreement with research work in literature.
The document discusses growing algae on nitrate-rich wastewater from Cambridge Water to reduce nitrate levels. Laboratory experiments found that several marine algae species could grow using nutrients from diluted brine wastewater. Larger scale experiments in photobioreactors confirmed one marine species, Phaeodactylum tricornutum, could effectively use nutrients from the wastewater. Future work involves optimizing growth of polar algae species and developing an innovation facility to further explore algal bioremediation applications.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
