description: Abstract

Crop yield estimation has significant importance for policy makers to make timely decisions on import/ export of particular crop. Another method for determining vegetation health and yield is the use of satellite imagery. Although several vegetative indices are being utilized, it is unknown how effective they are at estimating yield. This study compared several satellite-based vegetation indices, including the Enhanced Vegetation Index (EVI), Normalized Difference Vegetation Index (NDVI), Soil Adjusted Vegetation Index (SAVI), and Modified Soil Adjusted Vegetation Index (MSAVI), to determine which index is most appropriate for the central Punjab, Pakistan cropping area. The research focuses on analyzing the correlation between these vegetation indices and biomass/biological yield and grain yield. Through scatter plots and regression analyses, the study reveals strong positive correlations between these vegetation indices and crop yields, demonstrating their effectiveness as indicators for predicting agricultural productivity. SAVI and MSAVI showed high reliability in semi-arid regions by minimizing soil brightness effects. EVI, with its additional correction for soil and atmospheric influences, proved particularly effective in densely vegetated areas. NDVI also showed a significant correlation with crop yield but was found to be less effective in regions with sparse vegetation due to its sensitivity to soil reflectance. The results revealed that all vegetation indices have a positive correlation with wheat yield, but their predictive power varies. Model-1 of (Wheat Grain Yield), which incorporates all four indices, showed the best performance with an R-squared of 0.91 and a Pearson correlation of 0.95, indicating a strong fit to the observed data. However, its NSE value of 0.89 suggests moderate predictive reliability. Among the vegetation indices, NDVI emerged as the most significant predictor of yield due to its high positive coefficient in the regression models. These findings suggest that the appropriate selection of vegetation indices, considering environmental context, is crucial for accurate yield prediction.

description: We present, from first principles, a direct method for evaluating the exact fermion propagator in the presence of a general background field at finite temperature, which can be used to determine the finite temperature effective action for the system. As applications, we determine the complete one loop finite temperature effective actions for 0+1 dimensional QED as well as the Schwinger model. These effective actions, which are derived in the real time (closed time path) formalism, generate systematically all the Feynman amplitudes calculated in thermal perturbation theory and also show that the retarded (advanced) amplitudes vanish in these theories.

description: As land is developed, the impervious surfaces that are created increase the amount of runoff during rainfall events, disrupting the natural hydrologic cycle, with an increment in volume of runoff and in pollutant loadings. Pollutants deposited or derived from an activity on the land surface will likely end up in stormwater runoff in some concentration, such as nutrients, sediment, heavy metals, hydrocarbons, gasoline additives, pathogens, deicers, herbicides and pesticides. Several of these pollutants are particulate-bound, so it appears clear that sediment removal can provide significant water-quality improvements and it appears to be important the knowledge of the ability of stromwater treatment devices to retain particulate matter. For this reason three different units which remove sediments have been tested through laboratory. In particular a roadside gully pot has been tested under steady hydraulic conditions, varying the characteristics of the influent solids (diameter, particle size distribution and specific gravity). The efficiency in terms of particles retained has been evaluated as a function of influent flow rate and particles characteristics; results have been compared to efficiency evaluated applying an overflow rate model. Furthermore the role of particles settling velocity in efficiency determination has been investigated. After the experimental runs on the gully pot, a standard full-scale model of an hydrodynamic separator (HS) has been tested under unsteady influent flow rate condition, and constant solid concentration at the input. The results presented in this study illustrate that particle separation efficiency of the unit is predominately influenced by operating flow rate, which strongly affects the particles and hydraulic residence time of the system. The efficiency data have been compared to results obtained from a modified overflow rate model; moreover the residence time distribution has been experimentally determined through tracer analyses for several steady flow rates. Finally three testing experiments have been performed for two different configurations of a full-scale model of a clarifier (linear and crenulated) under unsteady influent flow rate condition, and constant solid concentration at the input. The results illustrate that particle separation efficiency of the unit is predominately influenced by the configuration of the unit itself. Turbidity measures have been used to compare turbidity with the suspended sediments concentration, in order to find a correlation between these two values, which can allow to have a measure of the sediments concentration simply installing a turbidity probe.

description: Quantum computing brings a promise of new approaches into computational quantum chemistry. While universal, fault-tolerant quantum computers are still not available, we want to utilize today's noisy quantum processors. One of their flagship applications is the variational quantum eigensolver (VQE) -- an algorithm to calculate the minimum energy of a physical Hamiltonian. In this study, we investigate how various types of errors affect the VQE, and how to efficiently use the available resources to produce precise computational results. We utilize a simulator of a noisy quantum device, an exact statevector simulator, as well as physical quantum hardware to study the VQE algorithm for molecular hydrogen. We find that the optimal way of running the hybrid classical-quantum optimization is to (i) allow some noise in intermediate energy evaluations, using fewer shots per step and fewer optimization iterations, but require high final readout precision, (ii) emphasize efficient problem encoding and ansatz parametrization, and (iii) run all experiments within a short time-frame, avoiding parameter drift with time. Nevertheless, current publicly available quantum resources are still very noisy and scarce/expensive, and even when using them efficiently it is quite difficult to obtain trustworthy calculations of molecular energies.

description: Abstract

Salinity poses a significant abiotic stress challenge that affects plant growth and development, ultimately reducing crop productivity. Owing to the genetic variability present in crop plants, they display a range of responses when faced with salinity stress. This diversity has allowed plant scientists to identify salt-tolerant crop varieties. As a key selection criterion, Plant breeders have been improved the salinity tolerance in different plants through prioritizing seed yield or plant vigor. The evaluation process become feasible and advantageous when crops show clear signs of the salinity tolerance at the cellular level, entire plant, or tissue levels. Salinity varies in the field; therefore, testing plants in a controlled environment with consistent saline conditions is reliable and effective. The hydroponic culture (soilless culture) method is frequently used to study how salinity affects crop plants, allowing researchers to observe the impacts of nutrient deficiencies and toxicities. In this study, 80 sunflower accessions were evaluated in a hydroponic culture for salinity tolerance. Statistical data were collected for the seedling parameters root and shoot lengths, fresh root and shoot weights, dry root and shoot weight, dry root and shoot weight, sodium potassium ratio stress indices. The 10 tolerant (A-18, A-37, A-78, A-35, A-13, A-10, A-30, A-58, A-6, A-64) and four sensitive accessions (A-28, A-80, A-73 and A-29) were carefully chosen based on computed indices from principal component analysis (PCA). In a controlled experimental assay, this study could be useful for comparing salinity indices and identifying salinity-tolerant sunflower accessions for future breeding initiatives.

description: The construction of a reference ontology for a large domain still remains an hard human task. The process is sometimes assisted by software tools that facilitate the information extraction from a textual corpus. Despite of the great use of XML Schema files on the internet and especially in the B2B domain, tools that offer a complete semantic analysis of XML schemas are really rare. In this paper we introduce Janus, a tool for automatically building a reference knowledge base starting from XML Schema files. Janus also provides different useful views to simplify B2B application integration.

description: We have investigated planetary accretion from planetesimals in terrestrial planet regions inside the ice line around M dwarf stars through N-body simulations including tidal interactions with disk gas. Because of low luminosity of M dwarfs, habitable zones (HZs) are located in inner regions. In the close-in HZ, type-I migration and the orbital decay induced by eccentricity damping are efficient according to the high disk gas density in the small orbital radii. In the case of full efficiency of type-I migration predicted by the linear theory, we found that protoplanets that migrate to the vicinity of the host star undergo close scatterings and collisions, and 4 to 6 planets eventually remain in mutual mean motion resonances and their orbits have small eccentricities and they are stable both before and after disk gas decays. In the case of slow migration, the resonant capture is so efficient that densely-packed ~ 40 small protoplanets remain in mutual mean motion resonances. In this case, they start orbit crossing, after the disk gas decays and eccentricity damping due to tidal interaction with gas is no more effective. Through merging of the protoplanets, several planets in widely-separated non-resonant orbits with relatively large eccentricities are formed. Thus, the final orbital configurations of the terrestrial planets around M dwarfs sensitively depend on strength of type-I migration. We also found that large amount of water-ice is delivered by type-I migration from outer regions and final planets near the inner disk edge around M dwarfs are generally abundant in water-ice except for the innermost one that is shielded by the outer planets, unless type-I migration speed is reduced by a factor of more than 100 from that predicted by the linear theory.

description: The RISC-V Instruction Set Architecture (ISA) maintains a surging interest both in industry and in academia due to its simplicity, extensibility, and open license. The integration of RISC-V ISA in the widely used gem5 simulator bridges the gap between RTL and ISA (Spike, QEMU) simulation, as it offers a micro-architectural simulator to the RISC-V ecosystem. This, however, raises uncertainty regarding the accuracy degree of the RISC-V related model implementations in gem5. Especially if we consider that they are still premature due to their recent adoption. The modelling accuracy is crucial as it is responsible for guiding properly research studies and pinpointing areas for optimization on various architectural design spaces. In this thesis, we aim to match the performance and energy costs of an ASIC RISC-V implementation, namely CVA6 (formerly known as Ariane), with a simulated RISC-V system in gem5. We present our experimental setup where we use the gem5 simulator to obtain the performance statistics and McPAT to estimate power and energy metrics. Afterwards, we proceed with an analysis plan to identify potential inaccuracies and flaws of the gem5 simulator. We then evaluate the performance of our simulated system using benchmarks from the RISC-V ecosystem and compare the results to published hardware implementations.

description: Abstract

Background and Aim: Indonesia is currently facing two problems: difficulty managing waste collection and rapid waste accumulation. Data in 2019 showed that Indonesia produced 67 million tons of waste of which 15% was plastic waste. Yogyakarta, as one of the major cities in Indonesia, also faces challenges in waste management. Every day, the amount of waste in Yogyakarta continues to increase. This increase in waste volume has led to a waste management crisis. One of the waste management sites in Yogyakarta, TPST Piyungan, has become a big issue in Yogyakarta because it is experiencing overcapacity, receiving an average of 700 tons of waste per day. So this study aims to determine the effect of social capital in Health empowerment on community participation in household waste management in Semail, Bantul, Yogyakarta. Materials and Methods: The type of research used is mixed research with a sequential exploration approach. This method begins with the use of qualitative methods, followed by quantitative methods, and ends with interpretation. A qualitative method with a phenomenological approach data collection techniques were carried out using observation, interviews with selected informants by snowball sampling and focus group discussions (FGD). Data analysis for quantitative data, namely univariate, bivariate, and multivariate. Results: Social capital has a positive and significant effect on attitudes and household and environmental waste management, but it does not affect community knowledge of waste management. Attitudes are positively and significantly influenced by knowledge; participation in household waste management is positively and significantly influenced by social capital; and attitudes and participation in waste management in the environment are positively and significantly influenced by participation in household waste management, attitudes, and social capital. Conclusion: A good waste management model in the community is designed by increasing participation in waste management in the family and the environment through strengthening attitudes by taking into account the social capital of the community. Strengthening attitudes also requires increasing public knowledge in waste management, either through counseling or health promotion.

title: Telepsychotherapy for the Treatment of Trichotillomania: A Randomized Controlled Trial
Creators: name: Lee, Eric B.
Publisher: name: Utah State University
Year: 2018

description: Trichotillomania is defined as recurrent pulling of one’s hair that results in distress and negative effects on general functioning and quality of life. Estimates of trichotillomania lifetime prevalence generally range from approximately 1% to 3% and it is likely as common as disorders such as obsessive-compulsive disorder and agoraphobia. Yet, quality treatment for trichotillomania is often difficult to find as many mental health professionals are uninformed about the disorder and its treatment. Moreover, mental health services in general are inaccessible to many with estimates suggesting that 96.5 million people do not have access to adequate services. The use of telepsychology has been an effective method for disseminating treatment services for a variety of mental health conditions. However, no research has examined the effectiveness of telepsychology to treat trichotillomania.
The current study reports the results of a randomized clinical trial of Acceptance and Commitment Therapy Enhanced Behavior Therapy for the treatment of trichotillomania delivered by way of telepsychology. The study compared an active treatment condition (n = 12) to a waitlist control condition (n = 10). Results showed significant reductions in hair pulling severity from pre- to post-treatment compared to the waitlist condition.
Participants in the waitlist condition received the same treatment as participants in the treatment condition following the waitlist period. All participants were then combined to examine overall treatment effects from pre-treatment to a 12-week follow-up. The effect of treatment on hair pulling severity was still significant at follow-up, however the effect was not as strong as at post-treatment. Conversely, the effect on quality of life was maintained and even increased following post-treatment. Additional measures of psychological flexibility, perceived shame, and valued action also saw significant changes from pre-treatment to follow-up. The findings demonstrate that telepsychology is a viable option to disseminate treatment for trichotillomania. Implications, limitations, and future research directions are discussed.

title: Estimation of Floods When Runoff Originates from Nonhomogeneous Sources
Creators: name: Olson, David Ray
Publisher: name: Utah State University
Year: 1979

description: Extreme value theory is used as a basis for deriving a distribution function for flood frequency analysis when runoff originates from nonhomogeneous sources. A modified least squares technique is used to estimate the parameters of the distribution function for eleven rivers. Goodness-of-fit statistics are computed and the distribution function is found to fit the data very well.
The derived distribution function is recommended as a base method for flood frequency analysis for rivers exhibiting nonhomogeneous sources of runoff if further investigation also proves to be positive.

description: We study the heat kernel for a Laplace type partial differential operator acting on smooth sections of a complex vector bundle with the structure group $G\times U(1)$ over a Riemannian manifold $M$ without boundary. The total connection on the vector bundle naturally splits into a $G$-connection and a U(1)-connection, which is assumed to have a parallel curvature $F$. We find a new local short time asymptotic expansion of the off-diagonal heat kernel $U(t|x,x')$ close to the diagonal of $M\times M$ assuming the curvature $F$ to be of order $t^{-1}$. The coefficients of this expansion are polynomial functions in the Riemann curvature tensor (and the curvature of the $G$-connection) and its derivatives with universal coefficients depending in a non-polynomial but analytic way on the curvature $F$, more precisely, on $tF$. These functions generate all terms quadratic and linear in the Riemann curvature and of arbitrary order in $F$ in the usual heat kernel coefficients. In that sense, we effectively sum up the usual short time heat kernel asymptotic expansion to all orders of the curvature $F$. We compute the first three coefficients (both diagonal and off-diagonal) of this new asymptotic expansion.

description: Quantum oscillations in both linear and Hall resistivities and weak antilocalization (WAL) are barely observed in bulk single crystals. Here we report the transport properties of a CaCuSb single crystal that crystallizes in the hexagonal crystal structure. The magnetotransport studies reveal WAL and Shubnikov-de Haas (SdH) quantum oscillations with a unique frequency at 314 T. A cusp-like behavior in the low field regime of magnetotransport for J // (ab)-plane and B // [0001] confirms the WAL in CaCuSb. Angular-dependent normalized magnetoconductance and SdH oscillations studies reveal that the observed phenomena originate from the 2D transport channels. The high magnetic field (up to 45 T) experiments demonstrate plateau-like features in the Hall measurements. The first-principles calculations unfold that CaCuSb is a non-topological semimetal with dominant hole carries at the Fermi level. Our study reveals that CaCuSb is a promising candidate to explore the quasi-2D quantum transport phenomenon in the transition metal pnictide materials.

description: Summary 

Detecting and managing neurocognitive disorders in children early and promoting effective rehabilitation allows them to develop their neurocognitive abilities in a normal manner. This study aims to identify such neurocognitive issues in students attending public schools and living in the rural area of Morocco’s Gharb plain. This study therefore evaluates the short-term memory and visual attention performance for a group of public school students. The psychometric tests include applying the digit span test in forward and backward order and the bells test for test on a sample of 235 students aged between 10 years 2 months and 14 years. The average age of the students was 11.99±0.95. According to the results of these tests, 63.4% and 16.6% of the students succeeded in the forward and backward digit span tests, respectively. The study also found a significant correlation between the students’ nutritional status and their performance in digit memorization, suggesting that malnutrition negatively impacts working memory performance, because only 37.1% gave correct answers with forward order of memorization and 14.3% when the order was reversed. When evaluating visual attention, the average score was 29 bells out of 35, with 37.8% of students having attention difficulties. Nevertheless, the children’s performance did not significantly differ based on their nutritional status.
title: Characterization of Black Walnut Genotypes for Resistance to Thousand Cankers Disease, Frost Hardiness and Other Desirable Horticultural Traits
Creators: name: Lauritzen, J. Elisa
Publisher: name: Utah State University
Year: 2018

description: The black walnut, Juglans nigra L., is native to the United States (USA) and is a valuable timber and nut tree. Just before the beginning of the 21st century, several western states observed a decline in the health and, later, death of black walnut trees. The pathogen-vector complex now known as thousand cankers disease (TCD) was shown to be the cause. The disease, caused by Geosmithia morbida Kolařik, is vectored by the walnut twig beetle (WTB), Pityophthorus juglandis Blackman. Thousands of WTB will swarm and enter a tree vectoring the fungus at each entry point where cankers then develop, quickly expand, coalesce and kill the branch or stem. The disease has been confirmed across the USA and in parts of Europe. The research and development of resistant cultivars is important to maintain native populations and livelihoods. The purpose of this project was to evaluate black walnut and hybrid trees for resistance to TCD through direct inoculation with the pathogen G. morbida. Inoculation of limbs took place in early summer of 2015, 2016 and 2017 at the Cyril Reed Funk Research Farm in Richmond, UT and Dayton, ID. Inoculated limbs were removed from the tree after senescence and canker size measured. An average of 336 trees were inoculated. One tree consistently exhibited resistance to TCD indicated by no canker staining. An additional 14 trees exhibited resistance for two of the three years. The results of this project indicate that breeding for resistance to TCD could be a management option for the disease.

description: Abstract

The main objective of this study is to explore how the use of mobile social media affects social cognition and physical activity habits of college students in Guangxi. A comprehensive research approach was adopted, combining a web-based questionnaire with detailed expert interviews to deeply analyze the interconnections between social cognition, mobile social media use, and physical exercise behavior, and to assess how individual differences affect this relationship. The analysis results revealed a significant positive relationship between social cognition and physical exercise behavior, and pointed out that mobile social media participation had a positive effect on promoting physical exercise. In addition, it was found that individual attributes such as gender, height and weight significantly affected the participation in physical exercise, and male students and students with moderate body size showed higher propensity to exercise.
title: Changing Nonhuman Impulsive Choice

description: Preference for smaller-sooner over larger-later rewards characterizes one type of impulsivity—impulsive choice. Impulsive choice is related to a number of maladaptive behaviors including substance abuse, pathological gambling, and poor health behaviors. As such, interventions designed to reduce impulsive choice may have therapeutic benefits. The purpose of this dissertation was to explore two methods to change nonhuman impulsive choice. In doing so, we hope to provide a baseline that future research can use to assess variables that are less amenable to human research (e.g., drug self-administration following reductions in impulsive choice). In Chapter 2, we failed to reduce nonhuman impulsive choice using working-memory training, a finding both inconsistent and consistent with the extant human literature. Chapters 3-5 sought to better understand a training regimen that generates large between-group differences in nonhuman impulsive choice—delay- and immediacy-exposure training. The results from Chapters 3 and 4 suggest that prolonged exposure to delayed food rewards produces large and long-lasting reductions in impulsive choice. Chapter 5 showed that the delay-exposure training effect can be obtained in fewer sessions than has previously been employed. A better understanding of the effects of delay-exposure training on nonhuman impulsive choice may have implications for the design and implementation of a human analog.

description: Background Adult Day care centres provide an important aspect of care provision through all phases of the dementia illness from diagnosis to the end of life (Dabelko HI 2008) supporting the well-being of both older people living with dementia and their care partners. Services within adult day care settings are designed to provide biopsychosocial health benefits to participants as well as care partner respite. Objective To examine research studies, literature reviews and grey literature and identify and map the literature on psychosocial interventions used in day care services for older people living with dementia and chart their use, evaluation and outcomes. The research review question is “what are the psychosocial interventions used in day care service for older people living with dementia?” Psychosocial interventions are important non-pharmacological interventions which support people’s wellbeing. Methods Inclusion/Exclusion criteria were identified and guided the search strategy. Participants were people aged 60 years and over living with dementia attending day care services. The use of psychosocial interventions for this cohort was the focus of the review. Databases were searched (Cochrane Reviews, CINAHL, Embase, Medline EBSCO, Medline Ovid, Medline PubMed, PsycINFO, Scopus, Open Grey, Lenus and WHO Global Index Medicus databases) using keywords/terms with Boolean operators from 2011 to 2023. Rayyan was used to extract and manage the data. Results The findings present a narrative and charting of the data from the 45 papers that met the review criteria, and this data is mapped onto the five objectives. Within this review, interventions were grouped into five broad types: nature (n = 6 papers), memory/cognitive (n = 11 papers), social (n = 17 papers), animal (n = 4 papers), or physical/sensory (n = 7 papers) based interventions. Conclusions This review has illustrated the wide variety in the types, range and facilitation of psychosocial interventions within adult day care services. This review highlights the potential benefits of these interventions. However, findings must be considered in the context that many were provided as brief intervention studies with little evidence of continuation after the study and further research is required given the complex and diverse range of interventions. Results will be of interest to practitioners planning to implement or evaluate psychosocial interventions used in day care services for older people living with dementia.

description: Abstract

Interview is a common data collection tool used in qualitative research. While qualitative interviews provide an excellent means to gain in-depth knowledge of people’s experiences from their own perspectives, a few potential risks can emerge during their conduct. Interviews will become more challenging when the potential participants involve a group of elites. Considering challenges related to access, power dynamics, technological issues, ethical considerations, and methodology, the purpose of this study is to identify some tips and tricks for a novice researcher in conducting elite interviews.  Using a reflection method in conducting interviews with police elite in Pakistan during my PhD study and analysis of related books and journals, this paper outlines tips and tricks for novice researchers who plan to interview elites as respondents of their studies.

description: In this paper, we propose to draw attention to the stability criterion of the superconductor current state. We use for this purpose the rough systems mathematical apparatus allowing us to relate the desired criterion with the dielectric permittivity of the matter and to identify the type of all possible phonons trajectories in its superconducting state. The state of superconductivity in the matter can be explained only by the phonons behavior peculiarity. And on the basis of the above-mentioned assumption, the corresponding mathematical model is constructed.

title: Targeted-Grazing as a Fuels Reduction Treatment: Evaluation of Vegetation Dynamics and Utilization Levels
Creators: name: Decker, Travis

description: Wildfires have caused concern as they have increased in severity and intensity over the last few decades. Land managers have sought management actions to mitigate the risk of wildfire by reducing fuel loads, thus decreasing wildfire intensity. Camp Williams is a National Guard camp near Bluffdale, Utah, where small arms and artillery training occurs. Managers at Camp Williams have created fuel breaks by implementing targeted sheep and goat grazing to remove fine fuel and thin brush. Management objectives set utilization of fine fuels (herbaceous) at 80% by weight. Questions arose regarding the ecological impact of the prescribed grazing rates in these fuel breaks. This study evaluated three fuel breaks and quantified the impacts of targeted sheep and goat grazing at 80% utilization. During the summer of 2015, herbaceous cover, shrub cover, shrub density, and bunch grass density was collected along eight paired (inside fuel break and outside fuel breaks) transects. Results indicate that the current management grazing plan could lead to an increase of invasive annual grasses, which may be counterproductive in fuel breaks. Often fine fuel treatments rely on high levels of grazing utilization (> 80%). However, high levels of utilization can lead to ecological degradation by reducing or eliminating native bunchgrasses. The objectives of the second study conducted were to determine how different levels of grazing utilization (30%, 50%, and 80%) relate to fuel characteristics and subsequent fire behavior. Results suggest that moderating grazing utilization levels (50%) may allow for more sustainable fuel reduction treatments while still reducing wildfire risks.

description: In this work we investigate the possibility of transporting material to the NEO region via the 8:3 MMR with Jupiter, potentially even material released from the dwarf planet Ceres. By applying the FLI map method to the 8:3 MMR region in the orbital plane of Ceres, we were able to distinguish between stable and unstable orbits. Subsequently, based on the FLI maps (for mean anomaly $M=60^\circ$ and also $M=30^\circ$), 500 of the most stable and 500 of the most unstable particles were integrated for $15\,Myr$ for each map. Long-term integration in the case of $M=60^\circ$ showed that most of the stable particles evolved, in general, in uneventful ways with only 0.8\% of particles reaching the limit of q $\leq$ 1.3 $AU$. However, in the case of $M=30^\circ$, a stable evolution was not confirmed. Over 40\% of particles reached orbits with q $\leq$ 1.3 $AU$ and numerous particles were ejected to hyperbolic orbits or orbits with a > 100 $AU$. The results for stable particles indicate that short-term FLI maps are more suitable for finding chaotic orbits, than for detecting the stable ones. A rough estimate shows that it is possible for material released from Ceres to get to the region of 8:3 MMR with Jupiter. A long-term integration of unstable particles in both cases showed that transportation of material via 8:3 MMR close to the Earth is possible.
