description: Bulgaria is famous for its soil fertility and very tasty fruits and vegetables.
Rearrangement of the land use after the political changes has not yet been finished.
The future association to the European Union will demand from us large amount of
agricultural goods. That involves land use changes and intensive fertilizer
application. The quality of the subsurface environment can be affected by these
agricultural activities. The fertilizers, moving below the soil root zone, may
contaminate underlying groundwater reservoirs. This is a serious problem, which
should be investigated and avoided as well as it is possible. One of the main tools
in that direction is the employment of mathematical models. The paper reports the
research accomplished for testing the abilities of such a model for solving
practical problems of land use.
WAVE is one of the models used for evaluation and prediction of nutrient leaching to
groundwater and surface water systems under the influence of fertilization, soil
properties, soil tillage, cropping pattern and hydrological conditions. The reported
investigation is done on a suitable rural region in Bulgaria- test field
Chelopechene, near to Sofia. During the modeling of the processes of water flow and
solute transport and transformation with the specific climate conditions arose many
problems. It was impossible to collect all information necessary for modeling.
Thanks to the available world database it was done a satisfactory simulation, with
analyzing the effects of different scenarios on nitrogen leaching from rural areas.
The model WAVE was developed for the Bulgarian conditions.

description: The newly discovered transient X-ray binary MAXI J1803-298 went into outburst on 1 May 2021, and was initially detected with MAXI/GSC. MAXI J1803-298 brightened in the hard state before undergoing a hard-to-soft state transition beginning on May 12. We report on the results of a NuSTAR Target-of-Opportunity (TOO) observation that began on 14 May, while MAXI J1803-298 was still in its intermediate state and near its peak outburst flux (~200 counts/s/FPM in NuSTAR). We observe clear reflection signatures in the source spectrum and carry out detailed modeling of the full NuSTAR spectrum with high-density reflection models. We are unable to constrain the black hole spin with our best-fitting model, which uses a lamppost geometry.

description: Budyko-based approaches are widely used to separate climate and catchment effects on streamflow changes. Considering the potential changes in streamflow, such separation is essential for future water resources management. In this study, we propose a method that allows for continuous disaggregation of climate and catchment impacts from the past to the future. We utilize a generalized linear model to represent catchment parameters based on climate and catchment features. Subsequently, we determine the future positions of the catchment in the Budyko-state space. This framework is applied to four Model Parameter Estimation Experiment (MOPEX) catchments with varying aridity indices in the USA. The results indicate that, in the recent historical period (1971–2011), climate change has contributed to increased streamflow in three catchments compared to the baseline (1948–1970) period. However, future projections indicate a mixed pattern of contributions in two of these catchments due to increased potential evapotranspiration, resulting in decreased streamflow.

description: This paper builds on the Reversed Time Particle Tracking Method of Bagtzoglou (2003)
and presents a novel methodology for time reversal in groundwater transport
simulations. The basis of the proposed scheme for anti-diffusion is a continuous
time, censored, nonlocal random walk capable of tracking groundwater solute
concentration profiles over time. Our analysis leads to the conclusion that an
adaptive (decreasing) time-stepping scheme is necessary in order to maintain a
constant amount of anti-diffusion. More specifically, we study the interrelations
between the following parameters: time-step evolution versus time or number of steps;
variance evolution (decrease rate); and total time or total number of steps required
to reach a fully anti-diffused solution. The approach is shown to be quite efficient
(every 80 time steps an eight-fold reduction of the variance is attained) and is also
asymptotically exact. Our method is applied to one-dimensional transport of
conservative solutes in spatially invariant and variant groundwater flow fields with
great success.

description: The INTEGRAL hard X-ray sources IGR J18007-4146 and IGR J15039-6061 were identified as candidate CVs using Chandra observations alongside optical/IR counterpart photometry. For this study we obtained simultaneous XMM-Newton and NuSTAR observations and carried out timing and spectra analyses. For both sources, we confirm an intermediate polar (IP) classification and measure the WD spin period as well as the WD mass. Both sources are heavier than average WD in IP systems, suggesting that follow-up of hard X-ray sources is a productive way to discover massive WDs.

description: Recent observations and modeling suggests acceleration of the hydrological cycle at
high latitudes in the Northern Hemisphere and that extreme intense precipitation
events were more frequent over the last 30 years of the twentieth century.
Assessments of local and regional impacts of changes in the hydrological cycle in
future climates call for improved capabilities for modeling the hydrological cycle
and its individual components at the subwatershed level. We have evaluated the
impact of climate change on stream flow in the Upper Mississippi River Basin by use
of a regional climate model (RCM) coupled with a hydrologic model - Soil and Water
Assessment Tool (SWAT) - and by use of an ensemble of GCMs producing output for the
IPCC 4th Assessment Report coupled to SWAT.  Both the RCM and the GCM ensemble
reproduce quite well the annual flow and interannual variability of observed
streamflow of the UMRB for the 20th Century.  Individual low-resolution GCMs give
poor simulation of annual streamflow, but the one high-resolution GCM tested gave
good results.

The RCM driven by a single GCM (HadCM2) results for the decade of the 2040s gave a
21% increase in future precipitation, which resulted in a 51% increase in surface
runoff, 43% increase in groundwater recharge, and 50% net increase in total water
yield in the UMRB on an annual basis.

Although there is inconsistency among GCMs, the ensemble-mean precipitation
increased of 6% due to climate change.  ET calculations give positive changes for
all models, likely due to warm-season temperature increases.  Substantial decreases
in snowfall suggest that warming is strong in winter.  Runoff decreases
substantially for most models, possibly due to enhanced drying of soils between
rains.  Total water yield varied widely among models, with the ensemble mean showing
almost no change from the contemporary climate.

description: A Natural Treatment System (NTS) Master Plan that includes a watershed-wide network of constructed wetlands was evaluated for treatment effectiveness of dry weather base flows and runoff from smaller more frequent storms in a 120 square mile (311 km2) urban watershed. The goal of the \342\200\230regional retrofit\342\200\231 wetland network is to serve as an integral component in watershed-wide Best management Practices (BMPs) for compliance with pollutant loading limits (TMDLs) requiring discharge limits of sediments, nutrients, pathogen indicators, pesticides, toxic organics, heavy metals, and selenium. The NTS Plan was assessed with \342\200\230planning-level\342\200\231 water quality models that account for the integrated effects of the planned 31 NTS facilities. The NTS Plan is estimated to achieve total nitrogen (TN) TMDL for base flows and reduce in-stream TN concentrations below current standards at most locations. Total phosphorous TMDL targets would be met in all but the wettest years. The fecal coliform TMDL would be met during the dry season, but not all wet season base flow conditions, and not under storm conditions. The NTS Plan is not designed to meet the sediment TMDL, but would capture, on average, about 800tons/yr (726,000 kg/yr) of sediment from urban areas. The wetlands are estimated to remove 13 percent of the total copper and lead, and 12 percent of the total zinc in storm runoff.The NTS Plan provides a cost-effective alternative to routing dry-weather flows to the sanitary system.

description: We report the results of NuStar observations of 3 young and energetic pulsars (Vela, PSR J1101-6101, and J1617-5055) which, nonetheless, exhibit quite different observational properties across the electromagnetic spectrum. Two of these pulsars are often dubbed MeV pulsars while Vela is a bright gamma-ray and radio pulsar. We present the energy-resolved lightcurves, phase resolved spectra, and also examine the pulsar-wind nebulae (PWNe) properties for Vela and PSR J1101-6101.

description: The restoration of native vegetation like pines helps mitigate soil erosion, but the effects of pine needle litter on runoff, erosion, and hydrology in karst hillslopes are unclear. This study investigated these factors during the rainy season from June to August 2021 under six treatments (flat, gentle, and steep slopes with and without pine needle coverings). The results showed that pine needle litter significantly increased the soil water content, particularly on steeper slopes, by improving the water-holding capacity. It also substantially reduced runoff (by 23.8%) and soil erosion (by 92.5%). The critical rainfall threshold for generating runoff did not occur in the pine needle covering treatment, whereas it was 19.3 ± 8.8 mm in the bare soil treatment under wet conditions. These findings highlight the efficacy of pine needle cover in reducing runoff and erosion in karst areas, promoting it as a sustainable method for restoring degraded soil.

description: Hydrologic and hydraulic modeling in the USEPA Stormwater Management Model (SWMM) were used to examine the effectiveness of typical stormwater management practices in reducing the potential for stream erosion. Fifty-year continuous simulations were used to produce flow duration curves and stream erosion rates for a variety of critical shear stress values representative of both cohesive and non-cohesive sediments. An excess shear stress erosion potential index was used to evaluate changes in erosion between undeveloped conditions of a 10 hectare watershed and four variations of post-development stormwater control. Evaluation of flow duration curves showed that when development takes place the duration of mid- to low-range discharges increase significantly, especially when detention practices are applied. In channels with low entrainment thresholds for bed and bank materials, e.g., sands and highly erodible clays, the significant increase of the duration of mid- to low-range discharges results in erosion potential index values greater than two regardless of the detention practices used. Overcontrol detention resulted in erosion potential index values of less than one, indicating a loss of erosion potential for bed materials such as most gravels (ds > 6 mm) and resistant clays that have critical shear stress values greater than four Pa.

description: The objective of the present work is to compare two methodologies based on multicriteria analysis for the evaluation of stormwater systems. The first methodology was developed in Brazil and is based on performance-cost analysis, the second one is ELECTRE III. Both methodologies were applied to a case study. Sensitivity and robustness analyses were then carried out. These analyses demonstrate that both methodologies bring equivalent results, and present low sensitivity and high robustness. These results prove that the Brazilian methodology is consistent and can be used safely in order to select a good solution or a small set of good solutions that could be compared with more detailed methods afterwards.

description: In this study, the performance of two popular conceptual models, a classic artificial intelligence (AI) model and a deep learning model is compared using simple and differential split-sample tests (SSST and DSST). Finally, the two conceptual models and the classic AI model are combined employing a model ensemble technique. The SSST and DSST schemes confirmed the ability of both types of models (conceptual and AI) to capture the hydrological response to rainfall events, although the conceptual models showed a better performance in the DSST scheme. The ensemble technique enhanced the modelling performance up to 22% and 35% in the calibration and verification steps. This study highlights the importance of applying differential-split sample test using existing data to build further confidence in model projections, and suggests that the use of model ensemble techniques combining conceptual and AI models can enhance the performance of rainfall-runoff modelling in the context of climate change.

description: Urban rainfall-runoff transports loads of particulate matter and total phosphorus (TP) from a variety of anthropogenic activities. Discharge of diffuse sources of phosphorus as a leading cause of receiving water eutrophication has received significant attention. Elevated phosphorus concentrations in rainfall-runoff have been commonly identified for many urban land uses. In some cases these phosphorus concentrations can approach levels of untreated wastewater plant influent. Particulate matter is also entrained with phosphorus in urban rainfall-runoff and this particulate matter encompasses a wide particle size gradation (1 ~ 4750 m). While particulate matter can be smaller than 1 m and larger than 4750 m, this size range encompasses the suspended, settleable and sediment fractions of particles. Though a variety of mechanisms the transport, fate and treatment of phosphorus is influenced by the physico-chemical properties and loading of particulate matter. The knowledge of particulate-bound total phosphorus (TP) distribution across the particulate size gradation can be used to assess removal and loading of phosphorus as a function of granulometric mass and design unit operations and processes (UOPs) targeting phosphorus associated with a particle gradation. This study investigated particulate-bound total phosphorus (TP) distribution from a series of rainfall-runoff events. The results indicate that particulate-bound TP and particulate matter mass follow similar distributions on an event basis and across a size gradation. In addition, results confirm that particulate-bound TP distributes across the entire particle size gradation. Particle gradations with larger total surface areas, under equal residence times and chemistry, generally have higher total phosphorus mass.

description: Management decisions regarding the potential fate and toxicity of anthropogenic metal elements requires knowledge of metal partitioning and speciation as mediated by in-situ control systems (ICS). This study focused on Cd, Zn, Cu and Pb, common anthropogenic metal elements generated in the built environment and examined the influence of variable event-based hydrology and passive ICS by an engineered partial exfiltration reactor (PER) system on partitioning and speciation. The feasibility and efficiency of the PER as an in-situ stormwater runoff control strategy to attenuate levels of metal elements was evaluated. Results indicate that higher rainfall intensity resulted in higher dissolved fraction (fd) values for influent Zn, Cu and Cd, but did not have a significant influence on partitioning of Pb. Speciation indicated that divalent fractions of Cd, Zn, Cu and Pb were changed marginally by the PER. Cu and Pb mainly complexed with organic matter in the influent, while carbonate complexes of these metals in the effluent significantly increased. The PER consistently and statistically reduced all loadings of Cd, Cu, Pb and Zn for all examined events, whether on a mass or concentration basis. As an unsaturated flow unit operation/process the PER can efficiently remove ionic or complexed forms of metal elements. Such UOPs are a potential quality and quantity ICS strategy for rainfall-runoff.

description: This study aimed to illustrate the impact of green human resources management on circular economy performance; the mediator role of green innovation; and the moderator roles of big data analytics and data-driven culture. A total of 438 survey questionnaires were collected from small and medium-sized enterprises from the Pakistani textile sector and evaluated through partial least square-structural equation modelling. The study’s outcomes revealed that green human resources management significantly impacts circular economy performance. Similarly, green innovation and big data analytics mediated and moderated between green human resources management and circular economy performance. Nevertheless, data-driven culture is needed to moderate between green human resources management and circular economy performance. The study presented a unique and novel idea of green human resources management concerning circular economy performance – the best solution for sustainable environmental fortification in the current decade while enhancing circular economy performance.

Publisher: name: 7th International CONCEIVE DESIGN IMPLEMENT OPERATE Conference
Year: 2011

description: The paper will provide a comprehensive account of the CDIO vision for Aston,
the reasons for changing from the established programme and didactic delivery
structure, how it has been implemented, the teaching and learning practices
that are being employed, the experiences of staff and students involved during
its development and practical implementation, and what lessons have been
learned from a successful 1st semester. Further to this there will be an
attempt to indicate what efficiencies have been gained from restructuring the
programmes around the CDIO framework, indicating some of the strengths of
adopting more active-learning strategies in modern engineering education.

title: Design and Analysis of Electrical Power and Communication Systems for 3U SeaLion CubeSat Mission
Creators: name: Siciliano, Joseph D.
Publisher: name: Old Dominion University Libraries
Year: 2022

description: Old Dominion University (ODU) Space Systems students in conjunction with the United States Coast Guard Academy (USCGA) are designing and developing a 3U Very Low Earth Orbit (VLEO) CubeSat mission aptly named SeaLion. This work specifically details the design of the Electrical Power System (EPS) and Communication System of the satellite. Electrical power in orbit is a precious commodity and must be carefully regulated and distributed to ensure the satellite’s operational health. Commonly, CubeSat electrical power is retained in orbit via outward facing solar cells and stored in onboard rechargeable batteries. This thesis proposes using non-rechargeable primary battery cells and custom hardware to maximize operational time with strict Very Low orbital lifetime constraints. Primary battery cell choice and the encompassing battery power supply design with reliability features are provided. Major functions of the EPS including voltage and current regulation and circuit protection and monitoring are also designed and analyzed for performance and reliability. The communication system consists of two half-duplex radios centered in the UHF and S-Band frequency bands to communicate with the Virginia CubeSat Constellation (VCC) and Mobile CubeSat Command and Communications (MC3) ground station networks, respectively. The design and analysis provided show the viability and cost efficiency of using primary cells and custom and readily available hardware for Very Low Earth Orbit CubeSat missions.

description: Universities are continually under pressure to do more in terms of delivery,
for less in terms of resources. For engineering and design courses,
particularly those where a high level of practical project work is expected,
this can be a particular challenge. The session will be structured around
participants taking part in a simple, low cost and hopefully enjoyable CDIO
activity in order to catalyse debate amongst participants on effective CDIO
learning under limited resource.

description: The stages of preparing high drug loaded pellets were investigated using static and dynamic imaging techniques to provide a greater understanding and ease the scale up process. An example of a real case laboratory and production scale quality by design (QbD) based development of pellets is demonstrated. Potential process analytical technology (PAT) approaches by dynamic image analysis (DIA) are presented in various process phases. Pellets were prepared at laboratory and production scale (high shear granulation, extrusion/spheronization, drying, and coating). The influence of process parameters on pellet properties (aspect ratio (AR), yield, pellet size, and their distribution) was investigated using static and DIA. During coating, we focused on the coating thickness and identification of potential agglomeration. The effects of kneading time, amount of water, extrusion screen plate (ESP) opening diameter and thickness on pellet properties were confirmed in accordance with literature. In terms of screw speed, spheronization speed and time, no considerable influence on pellet properties was observed in the range of studied process parameters, thereby confirming the design space. In addition to the ESP thickness and opening diameter, quality of the ESP impacts the pellet properties. Lastly, coating thickness measurements with dynamic and static image analysis were comparable and an exemplary case of in-line agglomeration detection was presented. Real-time evaluation with PATVIS APA is an effective PAT tool for the evaluation of spheronization (pellet size distribution, AR, and yield) and coating (coating thickness, agglomeration detection).

Prometheus, An Open-Source Simulation of Neutrino Telescopes
Creators: name: Olavarrieta, Santiago Giner
Publisher: name: Zenodo
Year: 2022

description: Since the weak sector is one of the only places explored by the Standard Model (SM), there is hope that studying neutrinos may provide insight into physics beyond the Standard Model (BSM). For this purpose, neutrino telescopes have broad programs searching for the effects of BSM physics; however, the phenomenological community, which predicts the observational effects of BSM models, does not have direct access to the simulation of neutrino telescopes and must approximate the detector response. This issue will only grow with the advent of a new global network of gigaton-scale detectors currently under construction, for there is no consistent simulation of these detectors. In this contribution, we present Prometheus, an open-source simulation of neutrino telescopes from neutrino injection to photon propagation that can therefore be used for studies both in the realm of SM physics, such as neutrino oscillations and point source analysis, as well as BSM physics. The flexible implementation allows for simulation in solid and liquid water and therefore allows for a consistent simulation of all existing and proposed gigaton-scale observatories.

description: While the CDIO standards and syllabus give a strong framework upon which to
develop good quality engineering programmes, the practical means by which
Universities and Colleges implement these is often less clear. We are therefore
keen to work with a number of institutions worldwide currently in the early
stages of CDIO implementation to help develop a knowledge base and support
network to help guide future partners in choosing and deploying a suitable CDIO
implementation strategy for their own organisation.
