description: Efficient utilization of all available carbons from lignocellulosic biomass is critical for the economic efficiency of a bioconversion process to produce renewable bioproducts. This dissertation aims to understand the fundamentals of bioconversion of biomass-derived carbons to polyhydroxyalkoate (PHA) by Pseudomonas strain. The key contributions of this work include the elucidation of two distinct kinetic patterns of PHA accumulation with benzoate under nitrogen-limited and surplus conditions (ammonium chloride form) in Pseudomonas putida KT2440. Moreover, a novel strategy—co-feeding glycerol and lignin derivatives such as benzoate, vanillin, and vanillic acid in P. putida KT2440—was developed for the first time, which simultaneously improved both cell biomass and PHA production. NMR metabolite analysis and global proteome profiles suggested the stimulated oxidative-stress responses altered the intracellular NAD+/NADH and NADPH/NADP+ ratios, up-regulated the proteins involved in energy generation and storage processes, including the Entner–Doudoroff (ED) pathway, the reductive TCA route, trehalose degradation, fatty acid β-oxidation, and PHA biosynthesis. Furthermore, the benzoate addition inhibited cell biomass and PHA production in the glucose system, presenting a divergent effect to glycerol. Global proteomics results revealed that in both glucose and glycerol co-feeding systems, the addition of benzoate dynamically regulated the energy-related pathways such as the ED/PP pathway, trehalose, and PHA biosynthesis pathways during early and late fermentation periods. Redox proteomics analysis results further confirmed that co-feeding benzoate with glucose dynamically regulates the energy generation pathway by increasing protein thiol oxidation in the PP pathway and glyoxylate shunt while decreasing fatty acid and trehalose metabolism, resulting in a smaller cell dry weight and PHA yield. These results showed that aromatics would not only serve as the carbon source but also generate distinct redox environments and finally reflected by different PHA accumulation patterns. In addition, the mechanisms of bacterial lignin depolymerization with P. putida were investigated via secretomic analysis. Depolymerization reaction mechanisms involved in a couple of oxidoreductases such as Dyp, multicopper oxidase, NAD(P)H dehydrogenase, glutathione reductase, glutathione S-transferases, choline dehydrogenase, and FAD-binding oxidoreductase, followed by β-Ο-4, β-β, β-5, and β-1 cleavage and aromatic intermediates release (e.g., vanillin and vanillic acid).
The Underwater Sound: Timbre and Beatmaking Process in Hip Hop Production, 1997-2018

description: The underwater sound is a term used within hip hop for the composition of instrumental tracks that accompany vocals, typically referred to as beats. In order to produce the underwater sound, beatmakers use a conglomeration of multiple audio effects including but not limited to low pass filtering, lowering the sample rate, and channel shifting, that, when combined, make the listener feel as if they are hearing the song while under water. I argue that the underwater sound has not only a distinct, audible timbre, but that it also signifies upon emotional vulnerability and coping with trauma via descriptions of how beatmakers have produced its timbral fingerprint. My analyses are spread across three short case studies: Kendrick Lamar’s “Swimming Pools (Drank)” (2012), Beyoncé’s “Hold Up” (2016), and Mac Miller’s “Self Care” (2018).

description: The Minimum Sum Coloring Problem (MSCP) is a variant of the well-known vertex coloring problem which has a number of AI related applications. Due to its theoretical and practical relevance, MSCP attracts increasing attention. The only existing review on the problem dates back to 2004 and mainly covers the history of MSCP and theoretical developments on specific graphs. In recent years, the field has witnessed significant progresses on approximation algorithms and practical solution algorithms. The purpose of this review is to provide a comprehensive inspection of the most recent and representative MSCP algorithms. To be informative, we identify the general framework followed by practical solution algorithms and the key ingredients that make them successful. By classifying the main search strategies and putting forward the critical elements of the reviewed methods, we wish to encourage future development of more powerful methods and motivate new applications.

description: This deliverable provides a description of the organization, framework and items needed to perform the evaluation of the PRACE-3IP pre-commercial procurement (PCP) results. The responsibilities, tasks and overall process for performing the evaluation will be discussed in detail and the key elements involved in the implementation will be identified. The document will be updated as necessary during the progress of the PCP.
 The PCP partners have formed an entity called the Group of Procurers (GoP) to supervise the PCP. Within this group, committees, working groups and roles have been designated for different tasks within the PCP process. A three-fold organization is to be used: steering of the PCP by a GoP Committee, execution of the evaluations by an Assessment Committee together with work package 8 and task 2.1 of PRACE-3IP, and coordination of the work by a pair of coordinators.
 The PCP process has been organized into two major stages, the tendering stage using an “open procedure” and the execution stage which consists of three progressive phases where the candidates are evaluated. During the PCP, there are four evaluation milestones, one in the tendering stage and three at the end of each of the phases in the execution stage.
 For the evaluation of the pilot systems to be developed, a set of representative applications and synthetic benchmarks have been selected to assess the solutions with realistic workloads. In order to quantify the energy-efficiency of the solution in a reliable and consistent way, we have also developed a set of procedures and requirements for analyzing the energy consumption of each proposed system using a virtual data centre concept.

Στην εργασία αυτή επιχειρούμε να αναδείξουμε, ότι η κάλυψη των κινεζικών Μ.Μ.Ε. (Μέσα Μαζικής Ενημέρωσης) είναι διαφορετική από εκείνη των “δυτικών” Μ.Μ.Ε. Αρχικά εξετάσαμε τις δυο πολεμικές συγκρούσεις και τι έχει συμβεί ως σήμερα, ώστε να είναι εύκολα κατανοητό το περιεχόμενο της ιστορίας και των κοινωνιών των οποίων εξετάσαμε. Έπειτα παρουσιάστηκαν τα κινεζικά Μ.Μ.Ε., που εξετάστηκαν οι θέσεις τους κατά την διάρκεια των πολέμων. Στο σημείο αυτό είναι ιδιαίτερα σημαντικό να τονιστεί, πως η περίοδος της εξέτασης των δημοσιευμάτων ξεκινά στις απαρχές του Ρωσο-ουκρανικού πολέμου (Φεβρουάριος του 2022, 24 Φεβρουάριου η ημέρα της ρωσικής εισβολής) και τελειώνει τον Οκτώβριο του ίδιου έτους ( την 31η ). Στην έρευνα αυτή προβλήθηκε και η μεθοδολογία της έρευνας στο περιεχόμενο, μέσω της κριτικής ανάλυσης λόγου και ποσοτικής ανάλυσης περιεχομένου, δηλαδή στην εστίαση της κάλυψης των κινεζικών Μ.Μ.Ε. και την περιγραφή των γεγονότων που έχουν συμβεί. Επιπρόσθετα αναδείχθηκαν οι ερευνητικοί σκοποί της έρευνας, μαζί με τα ευρήματά. Τέλος παρουσιάστηκε η έρευνα, που διεξήχθη στην παραπάνω εργασία με την εξαγωγή των συμπερασμάτων και δίνοντας απαντήσεις στις ερευνητικές υποθέσεις μας περί της κινεζικής κάλυψης και την απαραίτητη παράθεση της βιβλιογραφίας.
description: This paper examines Chinese media coverage of the war in Ukraine between the country and Russia, compared to the civil war in Yemen, in which external actors are actively involved. In this paper we attempt to show that the coverage of the Chinese media is different from that of the "Western" media. We first examined the two wars and what has happened up to the present day, so that the context of the history and societies we examined can be easily understood. Then the Chinese media were introduced, examining their positions during the wars. At this point, it is particularly important to emphasize that the period of the examination of the publications starts at the beginning of the Russo-Ukrainian war (February 2022, February 24 the day of the Russian invasion) and ends in October of the same year ( the 31st ). In this research, the methodology of the research on content was also raised, through critical discourse analysis and quantitative content analysis, i.e. focusing on the coverage of Chinese media and the description of the events that have occurred. In addition, the research objectives of the study were highlighted, along with the findings. Finally, the research, conducted in the above study was presented by drawing the conclusions and providing answers to our research hypotheses on Chinese coverage and the necessary citation of literature.

description: We study spatial coherence near a classical environment by loading a Bose-Einstein condensate into a magnetic lattice potential and observing diffraction. Even very close to a surface (5$\,μ$m), and even when the surface is at room temperature, spatial coherence persists for a relatively long time ($\ge$500$\,$ms). In addition, the observed spatial coherence extends over several lattice sites, a significantly greater distance than the atom-surface separation. This opens the door for atomic circuits, and may help elucidate the interplay between spatial dephasing, inter-atomic interactions, and external noise.

description: The United States requires labelling of food products containing major allergens, such as peanut, through the Food Allergen Labeling and Consumer Protection Act. Accurate labelling requires sensitive, specific and robust detection methods, and PCR-based techniques have proven highly effective. This article describes the transition of a previously developed multiplex real-time PCR assay for allergenic peanut to a droplet digital PCR format. The triplex droplet digital PCR assay was developed in a probe mixing format and directly compared to the established real-time PCR assay. Data are provided for thorough optimisation in the digital format, including the effects of primer and probe concentration, cycle number and annealing/extension time. Optimisation parameters influenced relative location and separation of droplet clusters but not final copy number. The droplet digital PCR assay was linear over five orders of magnitude; its lower limit of detection was 0.05 pg DNA per reaction, more sensitive than published digital PCR allergen assays. It was more precise, but not more sensitive, than the previously established real-time PCR assay.

description: We consider random walks indexed by arbitrary finite random or deterministic trees. We derive a simple sufficient criterion which ensures that the maximal displacement of the tree-indexed random walk is determined by a single large jump. This criterion is given in terms of four quantities : the tail and the expectation of the random walk steps, the height of the tree and the number of its vertices. The results are applied to critical Galton--Watson trees with offspring distributions in the domain of attraction of a stable law.

Europeanizing Space: How the European Commission Formulates and Instrumentalizes EU Identity and Interests in Earth Orbit
Creators: name: Morgan, Jay
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: In space, as in terrestrial contexts, the European Union does not behave like other actors on the world stage. Constructivism in international relations posits that actors’ identities shape their interests and behavior. Role theory provides an explanatory link between actors’ behavior and role conceptions. Through an inductive analysis of European Commission space policy documents, I argue that EU interests and strategy in space are shaped by its meta role identities as a civilian power and ‘global player’.  The EU’s space competencies are recently acquired. Previously, European space policy was solely the province of national governments and intergovernmental cooperation. I examine the supranationalization of space policy within the EU through a discursive institutionalist framework and find that the Commission has consistently pursued a strategy to legitimate the EU as the primary actor in European space policy. Furthermore, the Commission instrumentalizes space policy as a lever to drive European integration in other areas.

description: Since 2009 we are running a project to identify flashes produced by the impact of meteoroids on the surface of the Moon. For this purpose we are employing small telescopes and high-sensitivity CCD video cameras. To automatically identify these events a software package called MIDAS was developed and tested. This package can also perform the photometric analysis of these flashes and estimate the value of the luminous efficiency. Besides, we have implemented in MIDAS a new method to establish which is the likely source of the meteoroids (known meteoroid stream or sporadic background). The main features of this computer program are analyzed here, and some examples of lunar impact events are presented.

description: A new efficient magnetic solid-phase extractant based on a surface-modified magnetic mesoporous silica microsphere referred as MMSM-PEI was synthesised and used for the enrichment and isolation of copper ions (Cu2+) in preserved eggs. The physicochemical properties and morphology of MMSM-PEI were characterized by X-ray diffraction (XRD) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), vibration sample magnetometry (VSM), scanning electron microscopy (SEM) and thermos-gravimetric analyses (TGA). The concentrations of trace Cu2+ in the preserved egg were determined by flame atomic absorption spectroscopy (FAAS). The effects of important parameters were examined. The most suitable pH values and temperature for adsorbing Cu2+ were 6.5 and 25 °C, respectively. According to the determination of Cu2+ in egg white, egg yolk and the outer coating mixture (TOCM) of preserved eggs, the spiked recovery and RSD were 94.1–103.8% and 0.96–4.35%, respectively. The limit of detection (LOD) and the limit of quantitation (LOQ) were 0.14 mg/kg and 0.46 mg/kg, respectively. The developed method improved the sensitivity and accuracy of FAAS for the determination of Cu2+ and it could be applied to the determination of trace Cu2+ in real samples.

description: As a women’s wing organization of Muhammadiyah, Aisyiyah has been facing dilemma in reconciling its multiple identities as a woman, Muslim modernist and Indonesian organization. As part of the biggest Indonesian Muslim modernist movement with its ideology of progressive Islam, Aisyiyah has taken active parts in developing its socioreligious enterprises and economic empowerment of ummat/community at the grass-roots level. Aiming to critically analyze Aisyiyah’s economic empowerment programs using gender perspective, this paper will address a question to some extent Aisyiyah’s economic empowerment seek to accommodate and reconcile their multiple womanhood, modernist Muslim and Indonesian identities and interests. Using three indicators of women’s empowerment of resources, agency and achievements, it is argued that `Aisyiyah’s women economic empowerment has benefited from its resources as the oldest Muslim women’s organisations having vast networks and resulted in various economic empowerment institutions. Such great achievements cannot be detached from the ideological framework of modernist Muslims in Indonesia that is undergoing an evolution from the theology of tajdid/renewal movement with the emphasis on the development of socio-religious enterprises towards the theology of al-Ma`un seeking to make alignment and empowerment of the disadvantaged groups of the society, including the poor and women. However, in terms of agency, such Aisyiyah’s economic empowerment has been forced to serve the gender ideology of modernist Muslims that subordinates gender interests of women under the interests of ummat/community. However, such option is taken by Aisyiyah as a strategy to strike a balance of its identities and interests as a woman, a modernist Muslim, and Indonesian organization and a strategy to respond to its surrounding political contexts in Indonesia.
Not All Motivated Reasoning is Partisan: Perceived Vulnerability to Infectious Disease and Perceived Harmfulness Condition the Influence of Partisanship on Reasoning About COVID 19

description: Citizens are biased information processors, perceiving the world in line with cues sent to them by elites. As such, citizens might be deficient in their ability to hold elite agents responsible for policy failures. In this paper, I argue that an exception to this general pattern is when citizens’personalities introduce accuracy goals into their reasoning and thus lead them to hold elites accountable. I test this argument in the context of the COVID 19 pandemic in a diverse sample of N = 1885 Americans, and a two-wave panel study of n = 650 Americans. I find that a personality construct, Perceived Vulnerability to Infectious Disease (henceforth PVD), structures partisans’ perceptions of how harmful COVID 19 is, with those high in PVD being more likely to accept evidence that the disease is deadly. The effect is particularly strong for Republicans, for whom a factor of PVD moderates the effect of partisanship on perceptions of virus harmfulness. Harm perceptions in turn led voters to attribute responsibility for the crisis to political elites.

description: We present an innovative technique which allows the simultaneous measurement of the dielectric constant of a material at many frequencies, spanning a four orders of magnitude range chosen between 10 --2 Hz and 10 4 Hz. The sensitivity and accuracy are comparable to those obtained using standard single frequency techniques. The technique is based on three new and simple features: a) the precise real time correction of the amplication of a current amplier; b) the specic shape of the excitation signal and its frequency spectrum; and c) the precise synchronization between the generation of the excitation signal and the acquisition of the dielectric response signal. This technique is useful in the case of relatively fast dynamical measurements when the knowledge of the time evolution of the dielectric constant is needed.

title: Studies on the inhibition of plant pathogenic fungi by cyclohexylamine and spermidine analogues
Creators: name: Mackintosh, Caroline Anne
Publisher: name: University of Glasgow
Year: 1997
Subjects: subject: Plant pathology.

description: The potential inhibitory activity of several compounds against plant pathogenic fungal growth was studied. Prevention of growth was hypothesised to occur by the inhibition of polyamine biosynthesis and/or an effect on cellular functions associated with spermidine, the predominant polyamine in fungi. The spermidine synthase inhibitor, cyclohexylamine (CHA), and the spermidine analogue, norspermidine, demonstrated protective, eradicant and systemic activity against a range of plant pathogenic infections of host plants: broad bean rust and chocolate spot, barley and apple powdery mildew, and potato late blight. For example, both 2.0 mM CHA and 2.0 mM norspennidine, applied pre inoculation, reduced powdery mildew infection of barley by 88 %. CHA and norspermidine were equally effective although apple powdery mildew and potato late blight infections were slightly more responsive towards norspermidine than CHA treatment. Against bean rust and barley powdery mildew, little increased efficacy was afforded by increasing inhibitor concentrations from 0.5 mM to 2.0 mM. Higher concentrations were, however, more effective against the other pathogenic infections examined. Pre inoculation treatments tended to be more effective than post inoculation applications of the inhibitors, although the reason for this is unclear as microscopic examination of bean rust spores and developing germlings on bean leaves found little difference between the treated leaves and the untreated control, suggesting the compounds acted on later stages of fungal development. CHA and norspermidine were also effective against powdery mildew infection of spring barley in the field. The compounds were as effective as a commercially available fungicide in reducing disease. Neither the commercial fungicide nor the inhibitors caused any increase in yield over the untreated control, although this may have been the result of additional environmental pressures. The study therefore showed that CHA and spermidine analogues possessed both antifungal and fungicidal activity against a range of plant pathogens. Although differences in in vivo and in vitro studies exist, perturbation of polyamine biosynthesis was unlikely to account for such activity of the compounds. The compounds were most likely exerting their effects via some other cellular function related to polyamines. (Abstract shortened by ProQuest.).

description: We investigate the relationship between colour confinement and the gauge independent Cho-Duan-Ge Abelian decomposition. The decomposition is defined in terms of a colour field $n$; the principle novelty of our study is that we have defined this field in terms of the eigenvectors of the Wilson Loop. This establishes an equivalence between the path ordered integral of the non-Abelian gauge fields with an integral over an Abelian restricted gauge field which is tractable both theoretically and numerically in lattice QCD. We circumvent path ordering without needing an additional path integral. By using Stokes' theorem, we can compute the Wilson Loop in terms of a surface integral over a restricted field strength, and show that the restricted field strength may be dominated by certain structures, which occur when one of the quantities parametrising the colour field $n$ winds itself around a non-analyticity in the colour field. If they exist, these structures will lead to a area law scaling for the Wilson Loop and provide a mechanism for quark confinement. We search for these structures in quenched lattice QCD. We perform the Abelian decomposition, and compare the electric and magnetic fields with the patterns expected theoretically. We find that the restricted field strength is dominated by objects which may be peaks a single lattice spacing in size or extended string-like lines of electromagnetic flux. The objects are not isolated monopoles, as they generate electric fields in addition to magnetic fields, and the fields are not spherically symmetric, but may be either caused by a monopole/anti-monopole condensate, some other types of topological objects or a combination of these. Removing these peaks removes the area law scaling of the string tension, suggesting that they are responsible for confinement.

description: We study stochastic particle systems that conserve the particle density and exhibit a condensation transition due to particle interactions. We restrict our analysis to spatially homogeneous systems on finite lattices with stationary product measures, which includes previously studied zero-range or misanthrope processes. All known examples of such condensing processes are non-monotone, i.e. the dynamics do not preserve a partial ordering of the state space and the canonical measures (with a fixed number of particles) are not monotonically ordered. For our main result we prove that condensing homogeneous particle systems with finite critical density are necessarily non-monotone. On finite lattices condensation can occur even when the critical density is infinite, in this case we give an example of a condensing process that numerical evidence suggests is monotone, and give a partial proof of its monotonicity.

description: To compare the agreement and accuracy of complete blood counts (CBC) from capillary and venous blood sampled before and after acute aerobic exercise, 22 healthy men and women exercised for 40 minutes at 94% of ventilatory threshold. White blood cells increased by 51% (p<0.001) following acute exercise. There were no interactions of sampling site, time, and sex on CBC parameters. Lymphocytes, white blood cells, neutrophils, and hematocrit were slightly higher in venous blood after exercise. Lymphocytes, white blood cells, mixed cells, and neutrophils were strongly correlated at all timepoints (r>0.8, p<0.05) with good agreement, while mixed cells, hemoglobin, and hematocrit were strongly correlated at baseline (r>0.7, p<0.05), but showed weaker, non-significant correlations following exercise. These data suggest capillary sampling may be a useful alternative to venous sampling for measuring white blood cell counts following moderate intensity exercise, if differences between the sites fall within acceptable clinical limits.

description: The invariance of physical observables under disformal transformations is considered. It is known that conformal transformations leave physical observables invariant. However, whether it is true for disformal transformations is still an open question. In this paper, it is shown that a pure disformal transformation without any conformal factor is equivalent to rescaling the time coordinate. Since this rescaling applies equally to all the physical quantities, physics must be invariant under a disformal transformation, that is, neither causal structure, propagation speed nor any other property of the fields are affected by a disformal transformation itself. This fact is presented at the action level for gravitational and matter fields and it is illustrated with some examples of observable quantities. We also find the physical invariance for cosmological perturbations at linear and high orders in perturbation, extending previous studies. Finally, a comparison with Horndeski and beyond Horndeski theories under a disformal transformation is made.

description: Trimethylchlorosilane silylated silica aerogel (TS-SA) was loaded with a model drug, aspirin. TS-SA preparation, drug loading, and drying were performed through ambient pressure techniques in a safe and cheap manner. The sample structure, drug loading, and drug dissolution profiles were characterized by N2 adsorption and desorption analysis, FT-IR spectroscopy, UV absorption spectroscopy, FE-EM, EDX, XRD, and DSC. The characterization results indicated drug molecules are successfully loaded on the entire nanostructure of TS-SA. Specific surface area, total pore volume, and average pore size decrease with drug loading in TS-SA structure, as well as XRD and DSC results are indicating the amorphous state of loaded aspirin. Drug adsorption isotherm was measured and fitted well by the Freundlich model. Drug release kinetics from the samples were also evaluated in 0.1 N HCl (pH 1.2) and phosphate buffer (pH 7.4). The zero-order model, the first-order model, and the Higuchi model were employed to study the release kinetics. Better fitting to the Higuchi model showed that Fick's diffusion governs the aspirin release mechanism. The release rate of loaded samples was slower than the pure drug in both HCl and phosphate buffer. As pure aspirin dissolves totally in 0.1 N HCl and phosphate buffer within 40 min and 20 min, respectively, loaded drug dissolve 35% ± 4 and 80% ± 4 in 0.1 N HCl and phosphate buffer within 100 min. The ambient pressure drug loading on TS-SA could have interesting potential applications in controlled release drug delivery systems.

description: The dispersionless Kadomtsev-Petviashvili (dKP) equation $(u_t+uu_x)_x=u_{yy}$ is one of the simplest nonlinear wave equations describing two-dimensional shocks. To solve the dKP equation we use a coordinate transformation inspired by the method of characteristics for the one-dimensional Hopf equation $u_t+uu_x=0$. We show numerically that the solutions to the transformed equation do not develop shocks. This permits us to extend the dKP solution as the graph of a multivalued function beyond the critical time when the gradients blow up. This overturned solution is multivalued in a lip shape region in the $(x,y)$ plane, where the solution of the dKP equation exists in a weak sense only, and a shock front develops. A local expansion reveals the universal scaling structure of the shock, which after a suitable change of coordinates corresponds to a generic cusp catastrophe. We provide a heuristic derivation of the shock front position near the critical point for the solution of the dKP equation, and study the solution of the dKP equation when a small amount of dissipation is added. Using multiple-scale analysis, we show that in the limit of small dissipation and near the critical point of the dKP solution, the solution of the dissipative dKP equation converges to a Pearcey integral. We test and illustrate our results by detailed comparisons with numerical simulations of both the regularized equation, the dKP equation, and the asymptotic description given in terms of the Pearcey integral.

description: Boredom is a ubiquitous negative emotion. While most people occasionally experience boredom, people high in trait boredom are bored more frequently or have difficulty tolerating boredom. This was the first study to examine trait boredom in early childhood. Research with adults has identified two types of trait boredom which are linked to different motivational systems involved in self-regulation. Boredom susceptibility is associated with the behavioral activation system (BAS), which is sensitive to reward, whereas boredom proneness is associated with the behavioral inhibition system (BIS), which is sensitive to punishment (Gray, 1972, 1981; Mercer-Lynn et al., 2014). High levels of boredom proneness and susceptibility are associated with negative outcomes (e.g., anxiety, depression, substance use; Mercer-Lynn et al., 2014). Understanding whether these types of trait boredom are present in early childhood has implications for early intervention. Study 1 tested whether both types of trait boredom are observable in early childhood and show similar relations with BAS/BIS and executive function as observed in adults. Boredom susceptibility was positively associated with BAS sensitivity, while boredom proneness was marginally positively associated with BIS sensitivity. Study 2 investigated which strategies children employed to cope with boredom. Most children used social stimulation strategies (e.g., asking someone to play) and behavioral strategies (e.g., reading a book). Children’s boredom coping abilities were an important predictor of boredom proneness. Study 3 tested whether parental factors, such as modeling and boredom-related coaching, were associated with trait boredom in children. No significant findings were observed. This dissertation provides a foundation for future research on the origins and development of trait boredom and illustrates the need for early interventions to reduce trait boredom by helping children build effective coping skills. Further, this study illustrates differences in foundational regulatory processes for children high in trait boredom that suggests a need for tailored interventions for each type of trait boredom. Children high in boredom proneness may need help developing interests and strategies that will enable them to regulate boredom independently. Children high in boredom susceptibility may require coaching to help them tolerate boredom when it arises and determine an appropriate coping strategy.

description: The presence of fine particles has reduced the quality of water resources. Unfortunately, the fine particles normally take a longer time to be removed. Realizing this, the present study aims to employ a magnetic adsorbent to assist a fast separation of the fine particles from their solution. Here, micron-sized SiO2 particles were used as the model fine particles; meanwhile, the magnetic adsorbent was designed by functionalizing iron oxide nanoparticles (IONPs) with chitosan. A process study was done based on the effects of medium pH, IONPs concentration, and contact time. Results implied that both bare IONPs and chitosan functionalized-IONPs (denoted as CF-IONPs) were best in removing SiO2 at pH 4 owing to the electrostatic attraction force. However, as compared to the bare counterpart, CF-IONPs is more suitable for large scale application as it is effective in a wider pH range, requires lesser adsorbent dosage and shorter adsorption time. Despite that, removal of SiO2 using both types of adsorbents were found to follow pseudo-second order kinetic. The obtained data was modeled using either the moving least squares (MLS) or multivariable power least squares (MPLS) method. In particular, the indices of each parameter obtained from the MPLS-generated equation indicated that the most dominant parameter that governing the SiO2 removal by bare IONPs is medium pH, while the one for CF-IONPs is contact time.

description: The main motivation of our work is to create an efficient algorithm that decides hypertranscendence of solutions of linear differential equations, via the parameterized differential and Galois theories. To achieve this, we expand the representation theory of linear differential algebraic groups and develop new algorithms that calculate unipotent radicals of parameterized differential Galois groups for differential equations whose coefficients are rational functions. P. Berman and M.F. Singer presented an algorithm calculating the differential Galois group for differential equations without parameters whose differential operator is a composition of two completely reducible differential operators. We use their algorithm as a part of our algorithm. As a result, we find an effective criterion for the algebraic independence of the solutions of parameterized differential equations and all of their derivatives with respect to the parameter.
