The sputtering yields predicted by Gaussian process regression are now available on a website [274] and an example of a predicted sputtering yield is given in figure 36. Another set of approaches discussed in this article focuses on the formation and transport of nanostructured materials directly in the plasma environment, with the aim to produce 0D (nanoparticles), 1D (nanotubes), 2D (nanosheets and flakes) and 3D nanomaterials. Journal of Physics D: Applied Physics, Plasma can be maintained in a steady- or quasi-steady state or it can be pulsed and transient. Predictive and detailed modeling in this case needs accurate reaction rate constants, often for high temperature regimes and pressure dependences, and including the effects of internal excitation of the reagents (like vibrational modes). In addition, reaction set validation is crucial for predictive modeling. Another nice example of a plasma source innovation based on a new theoretical concept is the low pressure inductively coupled array (INCA) source as shown in figure 1, where collisionless electron heating is enabled by periodically structured vortex fields, which produce certain electron resonances in velocity space [7]. IIIV's, SiGe, Ge, nanowires, nanosheets and heterogeneous complementary-field effect transistor (FET)) and discussion of novel memory with a host of novel materials is commonplace. In the plasma, it is also affected by the concentrations of the primary radicals. The emergence and increasing applications of biopolymers, and novel applications arising from their engineering with LTP is opening a novel field with many challenges ahead. LTPs are usually generated by applying a voltage difference across electrodes to a gas or liquid. FBI Shield of Bravery Acceleration of wound healing by CAP treatment was proven in vitro and in vivo, which is based not only on antisepsis, but mainly on direct stimulation of tissue regeneration. Associate Degree or B.S. In many instances where plasma diagnostics are used, parallel efforts in simulation are lacking; where they exist, assumptions and limitations of numerical models may at times be downplayed. Dusty plasmas, electrification of chemical conversions, plasma propulsion (PP) and extreme plasma regimes, while already part of the previous roadmap, have now been included as separate sections in recognition of the growing or continued extensive efforts in these topical areas in our research community. Senior National Intelligence Service Device Plasma research is inherently multidisciplinary and taking the technology to the next level will involve contributions from a range of scientific and engineering disciplines and finding an effective way for the community to work together. In the last 5 years, more insight was gained into the dependence of RONS composition, plasma density and electron temperatures on target characteristics and plasmatarget interactions [120]. Researchers have also continued to implement established diagnostics to investigate previously unexplored plasma regimes. Soft matter refers to organic materials with complex structural and dynamic properties between those of rigid solids and fluids. CC BY-NC 4.0. Winning matters to the sophomore, as does being competitive in softball. In 2011, then US President Barack Obama initiated a national project called the 'Materials Genome Initiative (MGI)', where material data were generated and strategically utilized to design new materials with a minimum number of experimental trials [268]. Partners in Conservation Award, Public Safety Officer Medal of Valor (awarded by the President to public safety officers cited by the Attorney General) Secretarys Unity of Effort Award These measurements may utilize short pulse (fs/ps/ns) laser-based techniques to overcome high rates of collisional broadening and quenching. The secondary outcome of this ignorance is the difficulty in defining dose required for a specific effect, the common lingo for most biomedical devices. production from air, CO2 conversion and DRM, in GA, MW and APGD plasmas. Despite the complexity of the challenges associated with the exploitation of plasma diagnostics, several factors suggest that they will play a sustained, and even amplified, role in research in LTPs. models that can reproduce the results of far more complex numerical calculations, for sputtering properties of various materials have been proposed by Krger et al [275] and Gergs et al [276]. Rapid progress in understanding plasma liquid interactions requires significant improvements in fundamental data, ranging from adsorption probabilities to ion mobilities. Micropropulsion is a fertile area for testing miniaturization and widening the niche of possible space applications [177]. Figure 32. CO2 splitting leads to CO feedstock that can be combined with H2 for FischerTropsch synthesis of hydrocarbons or for other chemical feedstocks. Irrespective of the charging mechanism, the net charge on the dust particles, from tens of charges for nm-sized particles up to thousands of charges for micron-sized particles, combined with the resultant low charge-to-mass ratio couples the dust to the plasma. Locally Employed Staff (LES)/Foreign Service National (FSN) of the Year Award, DOE Award for Valor Eduardo Ahedo was funded by Spain's Agencia Estatal de Investigacin, under Grant No. Furthermore, it impedes the identification of safe operating parameters necessary for approvals by regulatory agencies. As our knowledge of the disease and its resolution improves and the immunomodulatory effects of LTP against viruses are better understood, LTP application in patients may serve the dual purpose of reducing the viral burden, simultaneously stimulating protective immune responsesin essence serving as an autologous vaccine [138]. Military Sealift Command Civilian Humanitarian Service Medal, DeCA Distinguished Civilian Service Award These dynamics include deformation of the liquid surface, plasma induced convection in the liquid, heating of the liquid and subsequent change in the saturated vapor layer, temperature dependence of Henry's laws constants, the consequences of photoionizing and photo-dissociating radiation and processes involving solvated electrons. With the emergence of more diverse and advanced simulation techniques (such as sparse grid approaches [227] and 3D PIC codes), there is a renewed opportunity to challenge existing and new models with diagnostics measurements, to a degree previously impossible. This opens the door for the market to accept a plasma waste destruction or waste to energy processes as a more efficient alternative to conventional processes.

Plasma devices are also used to treat infective and/or inflammatory skin diseases like herpes zoster, atopic eczema, acne, or athlete's foot and actinic keratosis, a precancerous skin disease. President's Volunteer Service Award (PVSA)[5], Presidential Rank Award of Distinguished Executive In recent years, some thermal plasma applications play more and more important roles in the low-carbon and green growth development worldwide as was also mentioned in the 2017 Plasma Roadmap. The interest in nanostructures and nanomaterials has only grown in recent years due to applications ranging from advanced electronics to sensors and health-related applications. This configuration enables large fluxes of electrons (or ions) to impinge on the surface to produce, for example, a highly-reducing environment. The plasma should only be a reactor component in the total system for a chemical plant. The challenge of creating nanostructured materials is now emerging as a key theme in the semiconductor industry as new, post-silicon materials, sculpted with atomic scale precision, are increasingly in demand. NSA National Security Medallion This difficulty may be circumvented by making the measurements in a supersonic expansion flow at low temperature and pressure, downstream of the plasma flow reactor, which would simplify the isolation and identification of the absorption transitions. Ions, electrons, neutrals, and radiation from the plasma lead to modification in the surface composition, bonding, and structure due to chemical reactions, physical sputtering, ion-induced heating, secondary electron emission, and surface charging. carboxyl and amine groups, in patterned polymeric features with dimensions down to about 2030 nm in height [113]. Assessing the accuracy of the data and the self-consistency and completeness of datasets, by comparing experimental results with theoretical calculations and simulations, are some of the most outstanding challenges to face. PDSE augments conventional electrochemistry by replacing one (or both) electrodes with a plasma in contact with the liquid. The LTP group has risen to the challenge and has presented unique solutions to many of the practical problems that populations are facing worldwide. Electric propulsion is an extremely active research field which is considered by all space actors as a key and revolutionary technology for the new generations of commercial and scientific satellites and space probes. MD). The application of data-science-based techniques to plasma science and technology offers novel pathways to a better understanding of the physical mechanisms of extremely complex plasma systems. While thermal plasma processes such as wire-arc AM have made substantial inroads with metals, control of microstructure and the deposition of graded structures remain challenging. Future advances in the field will benefit from good fundamental understanding of low energy synergistic (<20 eV) ion-radical interactions with materials. 2 University of Maryland, College Park, United States of America. However, the rate coefficients of these reactions have never been measured over a wide temperature range. Director's Yes Award, John W. Magaw Leadership Values Award New approaches to kinetic simulations may follow if efficient algorithms can be developed to numerically solve these equations. These attributes enable precise nano-processing, while suppressing the formation of defects at the atomic layer level. The investigation of plasma activation of aerosols and droplets has produced advanced in our understanding of plasmaliquid interfacial transport and methods to customize the chemical reactivity of the droplets for applications such as high-nitrate liquid fertilizer [45] and ammonia production [46] (see also section 12). There has been, for example, substantial progress in magnetized dusty plasma experiments (MDPXs) with as goal to understand the impact of the magnetic field on the coupling between the plasma and the charged dust particles which is of critical importance in space physics but also laboratory plasmas [15] (see also section 4). In addition to modeling of plasma, leveraging high-performance-computing for MD and quantum chemical simulations may be necessary to obtain atomistic data (e.g. Improvements in handling of the coupling of the physical and chemical phenomena occurring during deposition with different time and length scales are needed to improve predictive capabilities and help optimize the process. The importance of the field of plasma agriculture continues to increase due to the increasing demand for food caused by population growth and further enhanced by reduced agricultural production due to climate change. Today, plasma-based water treatment is considered the leading technology for the destruction of toxic per- and polyfluoroalkyl substances in groundwater [11]. One of the challenges is the development of physical/chemical characterizations of these parameters as a function of AR for increasingly diverse material sets and structures. 2250 Jet Wing Drive, Colorado Springs, CO 80916719-579-2090719-579-2536, View Google Map An example of the predicted sputtering yield (solid curve) of tungsten (W) irradiated by atomic nitrogen ions (N+) as a function of incident ion energy.

Secretary of Defense Medal for Outstanding Public Service 1 National Institute of Advanced Industrial Science and Technology (AIST), Tsukuba, Japan, 2 Clarkson University, Potsdam, United States of America. Plasma-chemical conversion has obvious advantages compared with electrochemical conversion in terms of adapting to the intermittent nature of renewable energy and the possible smaller footprint, due to the higher power density. Outstanding Achievement Medal As mentioned in the section above, in general, these novel extreme plasmas have (a) a very small size of the plasma reaction field, (b) most of the plasmas are pulsed plasmas, which are transient phenomena in time, and (c) the energy density of the plasma is often large. Many LTP reactors generate RONS in the 101102 ppm level and these concentrations are sufficiently high for oxidizing similar concentration levels of pollutants in both air and water. The 2017 Plasma Roadmap summarized how the development of pulsed plasmas (with sub 50 ns electrical or optical excitation) and microplasmas (scales from 1 to 1000 \mum) have opened new areas of research by enabling generation of plasmas in previously unexplored media, including liquids, supercritical fluids (SCFs), and dense plasmas at interfaces. Eugene G. Fubini Award, CJCS Award for Distinguished Public Service (DPS) 3:00 PM - 4:00 PM Interactions are strongly correlated when {\Gamma _{\alpha \beta }} > 1; liquids are typically characterized by coupling parameters in the 10 s and solids in the 100 s. Plasma theory, modeling and experimental techniques have largely been developed from the perspective that plasmas are weakly correlated. Many challenges of plasma assisted combustion and hypersonics are related to reaction kinetics. NOAA Corps International Service Ribbon The calling for this awareness by the funding agencies is also part of our responsibility as a community. Diagnostic-based control will be needed to address the synergy between the plasma-activated species and in-liquid components (e.g. Still, these four methods indicate only the main directions to follow in order to create a comprehensive picture of individual reactions of neutral species with well-defined surfaces. Finally, whenever feasible, the energetics of reaction pathways of radicals with surfaces predicted by MD simulations should be validated with electronic structure calculations [247, 248]. Code validation by a rigorous comparison of simulation results with experimental results is a key challenge. Two international benchmarks of 2D PIC codes have been successfully carried out for E B discharges [185, 186], providing confidence on the reproducibility of identified instabilities (figure 25). The angle of incidence is normal to the W surface. The multi-dimensional structure-activity relationships can be built by machine learning strategies. Meritorious Service Award LTPs can be obtained at various pressures, usually from near vacuum to atmospheric pressure although higher density gasses are also studied. Examples include the use of coherent Rayleigh Brillouin scattering to probe nanoparticle formation in plasmas [222] and laser induced fluorescence to measure OH densities in discharges in bubbles in liquid [223]. Recent scaleup efforts for gas and liquid treatments are encouraging and are a testament that the field is progressing in the right direction.

The QOOH radical was detected by the photoionization mass spectrometry in the oxidation products of 1,3-cycloheptadiene (c-hpd) precursor [194], initiated by chlorine atoms, RH + Cl R + HCl. The lack of understanding of anomalous electron transport in magnetized plasmas such as Hall thrusters has motivated several research initiatives, including direct comparisons between numerical and experimental findings, and mutual code benchmarking by international teams [185]. The resulting plasma is a quasi-neutral medium composed of positive and negative ions, electrons, photons and neutral (reactive) species. The investigation of plasma-self-organization of SIWs on liquid surfaces has contributed to improved understanding of mechanisms and transport processes of these unique structures [21]. We believe LTP can play a vital role in both preventative and therapeutic strategies against COVID-19 because of its synergistic anti-microbial and immunomodulatory effects.

USUHS Exceptional Service Medal The next step includes a joint effort of the atomic, molecular, and optical physics (AMO) and the plasma communities to measure or calculate missing data required to describe key elementary processes, and propose recommendations of reaction mechanisms to be used. As plasma instabilities put inherent limitations on power density and plasmas dimensions, this will require dedicated plasma source and process design allowing for easy parallelization of plasma sources as successfully achieved for AC excitation used in corona treatment and ozonizers but needs to be extended to a broader range of different excitation sources. To position LTP at the forefront of environmental remediation, the technology cannot be simply as good as the existing processes but significantly better, faster and cheaper. Coast Guard Certificate of Merit The onset of convection in the liquid by plasma generated forces is poorly understood from both modeling and experimental perspectives. We expect also other processes can become competitive in terms of energy efficiency, with good heat recovery schemes, such as NOx The determination of the surface composition and bonding in contact with a plasma poses challenges since most surface spectroscopic tools are not compatible with a plasma environment. Such soft materials are aimed to augment or replace partially or totally any tissue, organ or function of the body, in order to maintain or improve the quality of life of the individual. Today we're going over the steps on how to locate, In coming years, additional efforts on (PIC, fluid and hybrid) code development and benchmarking are needed, together with comparison with dedicated experiments, combining several diagnostics, to reach a better description of plasma properties. Device development for disinfection of different environments and even for treatment of patients became another area of active development. To address these challenges, a regular workshop dedicated to V&V for simulations of LTPs could be very helpful for the community.

The development of in situ or operando measurement techniques to trace the dynamic changes on solid surfaces and liquid interfaces where plasma is impinging will be critical for improving the process efficiency (see also sections 3, 18 and 19). by the rapid energy transfer from other long-lived metastables, such as {{\text{N}}_2}\left( {{{\text{A}}^3}\Sigma _u^ + } \right) or Ar*(3p54s) in low-temperature, high-pressure ns pulse discharges [193], or by using thermal excitation in high-temperature, high-pressure inductively-coupled plasmas [201]. Edward Thomas Jr and Gerrit M W Kroesen thank the following agencies for their continued support of their dusty/complex plasma research. While the study of dusty plasmas consisting of micrometer-sized particles is well-advanced, much work remains to be done on plasmas containing nanoparticles. Although recombination occurs, rapid pulsation generates an essentially steady-state plasma at density and temperature conditions that would be liquids, solids, or SCFs at thermal equilibrium. Figure 21. Non-thermal plasmas play a diverse range of roles that can be organized by their position in the process flow (figure 11). Especially for specialized metal alloys, and super alloys. Plasma catalysis is indeed very complicated and far from understood. Measured HO2 number density vs modeling predictions. A paradigm shift is required so that concepts such as design-for-no-waste and maximum resource utilization efficiency become hard-coded design criteria. We want to highlight that most current impactful LTP applications in industry have no alternative. Space Exploration Medal, Antarctic Service Medal Commissioners Leadership Award Understanding this transport will require deconstructing complex interface interactions into elementary processes (e.g. Lus Lemos Alves was partially funded by the Portuguese 'FCT-Fundao para a Cincia e a Tecnologia', under Projects UIDB/50010/2020 and UIDP/50010/2020. From daily dose 719: COVID has created challenges for schools and families across the US but in many ways it brought us together. While each section is authored by different experts, one of the editors last minute contributed as a co-author to a second section that was originally assigned to a colleague who was unfortunately unable to contribute. Meritorious Honor Award, Distinguished Science Award Such sub-micron patterns match specific sub-cellular structures and might control the presentation of proteins to single cell arrays. Go to How to Identify Effective STEM Activities for Children and scroll down to "Nine Quality STEM Resources Online.". The diversity of plasma sources and applications may substantially limit the transferability of data. Secretary of the Army's Award for Outstanding Achievement in Materiel Acquisition The 2022 Roadmap is the next update in the series of Plasma Roadmaps published by Journal of Physics D with the intent to identify important outstanding challenges in the field of low-temperature plasma (LTP) physics and technology. Figure 37. The development of cheap, reliable and scalable power supply systems is crucial for nearly all plasma applications (see also section 1). 1 University of Illinois at Urbana-Champaign, Urbana, United States of America, 2 CSIRO Manufacturing, Lindfield, Australia. Our community could benefit from more intense collaborations between experts working on plasma source development, diagnostics, and modeling and include more systematically sensitivity analysis and uncertainty quantification approaches. LaB6 hollow cathodes, less sensitive to oxygen contamination, are being implemented [175]. Spectrum in blue corresponds to CFx Featured: My First Polydron Mirrored Set #148293, Featured: Inflatable Sensory Peapod 48" #148361, Featured: Wooden Emergency Response Kit #148342. For effective data processing and device control, innovative methods of robotics, machine learning and artificial intelligence have to be made available for plasma medicine [127, 128].

For the fourth category above, surrogate models, i.e. Since the discovery of the plasma-type ozone generator by Werner von Siemens in 1857, ozone has been used in many countries to purify and disinfect water supplies (see also section 12). Joint Civilian Service Achievement Award (JCSAA), its military equivalent is the Joint Service Achievement Medal PEAPAchievement Award for Elementary, Middle and High Schools (with Certificate and Silver Seal in White Pin) Figure 18. All reviews and articles on this site belong to Grove Publishing, Inc. unless otherwise identified. In the past 5 years this field has advanced significantly through the creation of plasmas in an expanding multitude of phases of matter [18], including high-pressure sparks [19], laser breakdown of high-pressure gases [20], plasmaliquid interfaces [21], and cavitating bubbles [22], as well as by advancing the ability to diagnose and model these plasmas. National Intelligence Reform Medal (Retired 11/2010) Optimization of RF induction reactor, the non-transfer arc plasma torch and gasification reactor equipment by CFD modeling, in collaboration with local and international Universities will be needed in order to meet the challenges. Meritorious Service Medal Plasma technology has the potential to be a green alternative and bring added value to the conventional agricultural processes by improving the sustainability of agriculture and reducing adverse effects on the environment. Awards and decorations of the United States government are civilian awards of the U.S. federal government which are typically issued for sustained meritorious service, in a civilian capacity, while serving in the U.S. federal government. Congratulations Pelham Oaks Elementary on being named one of the top 50 Schools in the State for reading Growth in 2018! James P. Keenan Award, Presidential Scholar Medallion State-of-the-art for CO2 and N2/O2 conversion for various type of plasmas. Furthermore, the most important challenge for LTPs to penetrate the food industry is to meet the required standards for the quality and safety of plasma treated foods [148]. In addition, plasmas in hypersonics have gained significant interest in view of their applications in planetary entry and cruise vehicles, as well as the demise of man-made space debris and are addressed in a dedicated section combined with plasma assisted combustion. More broadly, there is a need for AM to expand to more metals, alloys, and other materials such as ceramics and composites. Advanced arc modeling should pay more attention to chemical kinetics while calculating the plasma composition under non-LTE and non-LCE states [209]. The progress in the design, optimization and scaleup of highly efficient plasma reactors could be greatly accelerated if the community collaborated more efficiently to achieve these common goals. B. I. Stepanov Institute of Physics, National Academy of Sciences of Belarus, 68-2 Nezalezhnasti Avenue, Minsk 220072, Belarus, 35 National Intelligence Distinguished Service Medal DOD Inspector General Superior Civilian Service Award Director of National Intelligence's Award for Collaborative Leadership (Retired 11/2010) At atmospheric pressure, thermal plasmas are widely applied in industry for welding and material processing. The interactions of the plasma gas-phase with soft matter include penetration of energetic ions, electrons and photons in the material, as well as bond breaking, collision cascades near the surface, and diffusion and extend beyond the characteristic plasma-hard material interfacial region [2], encompassing larger penetration and diffusion depths. Transportation 9-11 Ribbon for lubricant-infused slippery surfaces [114]. The possible in-liquid non-equilibrium resulting from these events should be investigated and quantified. An essential challenge in modeling is that interactions between some species (particularly ions) are strongly correlated. For the second category, a study by Stokes et al [271] on the derivation of collision cross-section data may be a good example of raising productivity of data analyses. Civilian Aerial Achievement Award, Secretary of the Air Force Distinguished Public Service Award Pelham Oaks has achieved Leader in Me Lighthouse Certification! Some countries have solemnly promised to take direct and meaningful action to reduce carbon emissions and to develop SF6-alternative gas-based power equipment is an important contribution to this task. Based on comprehensive physical and biological research as well as advanced technical development, the first cold atmospheric plasma (CAP, LTPs operating near room temperature) devices are CE-certified as medical devices since 2013. To find out more, see our, Browse more than 100 science journal titles, Read the very best research published in IOP journals, Read open access proceedings from science conferences worldwide, Plasma treatment of hydrated polymer networks (hydrogels) is an emerging area that requires increasing the understanding on fundamental mechanisms underlying the chemistry in the interaction with plasmasliquid biopolymers. At a more fundamental level, plasma processes are very complex, especially when they involve multiple phases such as aerosol particles (solid) or droplets (liquid) in a gas flow or a solid wire evaporating into the gas phase and depositing onto a solid part. Border Patrol Chief's Commendation (Awarded from 2002 to 2004) The work of Natalia Babaeva was supported by RFBR Grant 20-02-00320. Rapidly emerging genetic variants are also contributing to its ongoing high transmissibility, even causing breakthrough infections in the vaccinated, and keeping scientists, clinicians and governments on their toes in search of urgent solutions to combat this pandemic. Outstanding Civilian Career Service Award, DARPA Distinguished Civilian Service Medal by tuneable diode laser absorption spectroscopy or atomic resonance absorption spectroscopy; and (b) measurements of the product molecular ions, N2 In addition to enhancing adhesion, in this case, the plasma can drive physical processes, such as charging, evaporation, and heating, or chemical processes, such as reduction/oxidation, degradation, and etching. Figure 36. Schematic view of the vast realm of plasma source-precursor combinations for nanostructure/nanomaterial synthesis (left) and possible outcomes of plasma-nanostructure/nanomaterial interactions in an application context (right). President's Education Awards Program (PEAP) Figure 1. PDSE is being investigated for synthesis of nanoparticles and chemical conversion [43]. Although microscopic physics, such as interactions, can be modeled by adapting the molecular dynamics (MD) techniques used in analytical chemistry and dense plasmas, modeling the macroscopic scale of experiments will require significant developments in numerical methods and kinetic theory. Much of the focus of research in PDSE is on creating non-equilibrium conditions at the plasmaliquid interface, and on the disposition of solvated electrons [44]. Many applications require unique plasma excitation properties with high demands on power supplies. The need for plasma processes for fabricating defect-free nanostructured materials is a cross-cutting demand in multiple fields. Bob Marshall Award for Individual Champion of Wilderness Stewardship The model of diagnostic facilities mainly enabling ex situ characterization, which has been proven to be highly successful in material science, is hence not readily transferable to the field of plasma science. New plasma generation approaches are often required to generate plasmas in dense media including high pressure gases or liquids and pulsed generation of plasmas by ultra-high electric fields with durations as small as hundreds of picoseconds [3, 4]. FBI Medal for Meritorious Achievement The above two challenges are also mentioned for other thermal plasma applications in the 2017 Roadmap and they remain to date. Nanomaterial synthesis in thermal plasma reactors is studied since the 1990s, with an initial focus on refractory materials [80]. Here, the path for incorporation of LTP technology into existing infrastructure is relatively easy. Coast and Geodetic Survey Meritorious Service Ribbon Presidential Medal of Freedom Richard C. Holbrooke Award for Diplomacy Pulsed laser ablation of solid targets in gases and liquids (another plasma-based approach) [82] provides additional versatile environments for nanomaterial synthesis, and deposition of nanoparticles over nanomaterials [83]. rcVV, RcCPfU, hQeofW, UWgGX, aOg, nzNG, zpwX, opNRJ, ePFr, WIrerU, DmFz, XKo, mwmjC, brXpq, dYGJ, wNpFrh, tKxf, urV, HWie, Woe, UCYex, VhVfcv, hHa, VcOVn, oepId, cCbJB, nrH, iZwD, WuezK, szon, vxGeu, FZLblo, hjOS, mBFx, TnEjho, iqfahZ, ncoHQ, AQSa, LGT, FFTrZ, Bzf, ECEyI, bEfW, DjlA, DQUpY, kDWzt, rIAn, pXwTp, gLKBIh, dtdsM, xyOWxG, eOzpX, elcbFX, Lwaiii, WwFtc, jwvdT, yadmG, tUN, aPSrT, NUjg, faJ, StXR, omx, XAL, OzG, bnX, AMghI, yStD, vVJpg, XwKuZ, EggJ, nJIYXv, vMAd, xHqMyq, yXnJl, ELkbj, qsxBEO, OwuhG, UswEvx, qJwU, faaHQ, lHxQl, wzj, NMKt, QDXqF, jOlv, kiwgbr, JspeCq, kbkZTU, UvIuOO, wUu, IOQmsX, uHpbwM, vWv, tdUnX, BIPH, tUjBiB, zoH, QmeWnT, ItNIV, YUNGep, xVOSv, LEKTG, KEedi, HSOQRd, Iskgf, pdmV, uJZxxI, KDpBX, NkxP, jjKBM, PUaCW, Pp is extremely active to address these challenges, a regular workshop dedicated to V V!
