The document summarizes an in situ biotic/abiotic treatability study at Installation Restoration Site 28 to determine if contaminated groundwater can be remediated. Pilot tests were conducted in three areas using different treatment approaches: emulsified vegetable oil and microbes in one area, lactate and microbes in another, and zero-valent iron with carbon in the third. Groundwater was monitored before and after substrate injection to evaluate changes in contaminant levels and indicator parameters. Initial results show decreases in chlorinated ethenes and increases in reaction byproducts, suggesting the conditions support contaminant degradation.
1) The document describes a study to develop a continuous gradient assisted hydrophobic interaction chromatography process using Simulated Moving Bed (SMB-HIC) for the purification of recombinant streptokinase (rec-stk) from E. coli cell homogenate.
2) Key steps included producing and purifying rec-stk, estimating adsorption isotherms, designing a 3-zone open loop SMB system using a scanning program, and experimental realization of the SMB process.
3) Simulation studies were conducted to identify separation regions using equilibrium theory and stage models, and operating points were selected for experimental validation of the continuous purification of rec-stk via SMB-HIC.
The document discusses the use of Moving Bed Technology for wastewater treatment in small communities. It analyzes cases studying various configurations including MBBR reactors for organic matter and nutrient removal from wastewater flows of 300 m3/day from communities of 1,500 people. The configurations are compared in terms of dimensioning, investment costs of approximately €30-67/person, operating costs, and performance ratios. Key advantages of MBBR include easy operation, robustness, higher nitrification rates, and potential for increased biogas production from sludge.

1) An 11-month field pilot test was conducted using permeable reactive barriers of EHC™ and KB-1® to treat groundwater contaminated with TCE, cis-1,2-DCE, and VC at a site near a river. 2) The treatment successfully reduced contaminant concentrations to below regulatory levels at the riverbank and reduced TCE by 99.5% in the source area. 3) Monitoring of secondary effects showed that the treatment did not increase concentrations of arsenic or manganese as initially feared, but instead significantly reduced concentrations of iron, cyanide, sulfate and manganese through precipitation reactions under low redox conditions.
This document discusses using cyclic olefin copolymers (COCs) to enhance thermoforming of polyolefin films. COCs improve properties like dimensional stability, transparency, and heat resistance compared to traditional polyolefins. Testing showed that incorporating COCs into polyolefin films via monolayer blends or discrete multilayer structures improved properties of thermoformed parts like reduced gauge variation, increased bottom thickness and corner thickness, and higher puncture resistance and energy absorption. The discrete multilayer structures provided better mechanical properties than equivalent monolayer blends, with benefits increasing with higher COC content.
Proyecto A Gran Escala Hydromentia PresentationH2RAmbiental
This document discusses phosphorus and nitrogen treatment alternatives for improving water quality in Lake Okeechobee and surrounding areas. It describes the performance of managed aquatic plant systems (MAPS) like algal turf scrubbers (ATS) and water hyacinth scrubbers (WHS) in removing phosphorus and nitrogen from water. MAPS systems have proven effective at nutrient removal and generate biomass that can be used to produce compost for agricultural markets. The document argues that centralized MAPS regional treatment systems could help meet total maximum daily load regulations in a more cost-effective way than other options like storage reservoirs or treatment wetlands.
The document summarizes research on controlling noise from a supersonic jet impinging on a surface. Previous strategies involved modifications to the nozzle or shear layer near the nozzle exit. The current strategy involves placing a porous surface near the impingement point to disrupt feedback in the flow. Experiments were conducted in a STOVL facility and used acoustic measurements, unsteady pressure measurements, and PIV to analyze the flowfield and noise with and without passive control from the porous surface or active control from microjets. Results showed that both control methods reduced noise, but combining them produced greater noise reductions than either individually.
The document describes the development of a laboratory scale conical spouted bed reactor for biomass gasification. Initial experiments involve cold flow studies to establish stable spouting conditions. Future work includes hot flow studies and thermodynamic modeling to evaluate favorable operating conditions for hydrogen-rich syngas production from fuels like glycerol and propane. Existing correlations for minimum spouting velocity were found to be inadequate, so a new correlation was developed that showed excellent agreement with experimental data. Preliminary equilibrium analysis of reforming systems indicates steam reforming produces less hydrogen than partial oxidation or auto-thermal reforming. Further experiments are needed to validate the modeling results.

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.

In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
