description: We report on the Submillimeter Array (SMA) observations of molecular lines at 270 GHz toward W3(OH) and W3(H$_2$O) complex. Although previous observations already resolved the W3(H$_2$O) into two or three sub-components, the physical and chemical properties of the two sources are not well constrained. Our SMA observations clearly resolved W3(OH) and W3(H$_2$O) continuum cores. Taking the advantage of the line fitting tool XCLASS, we identified and modeled a rich molecular spectrum in this complex, including multiple CH$_3$CN and CH$_3$OH transitions in both cores. HDO, C$_2$H$_5$CN, O$^{13}$CS, and vibrationally excited lines of HCN, CH$_3$CN, and CH$_3$OCHO were only detected in W3(H$_2$O). We calculate gas temperatures and column densities for both cores. The results show that W3(H$_{2}$O) has higher gas temperatures, and larger column densities than W3(OH) as previously observed, suggesting physical and chemical differences between the two cores. We compare the molecular abundances in W3(H$_2$O) to those in the Sgr B2(N) hot core, the Orion KL hot core and the Orion Compact Ridge, and discuss the chemical origin of specific species. An east-west velocity gradient is seen in W3(H$_2$O), and the extension is consistent with the bipolar outflow orientation traced by water masers and radio jets. A north-south velocity gradient across W3(OH) is also observed. However, with current observations we can not assure if the velocity gradients are caused by rotation, outflow or radial velocity differences of the sub-components in W3(OH).

description: Die vorliegende Masterarbeit beschäftigt sich mit dem Einfluss vom frühen Einsatz lautsprachunterstützender Gebärden (LUG) auf die kindliche Kommunikationsentwicklung. Die wissenschaftliche Vorgehensweise mündet in der Kombination einer intensiven Auseinandersetzung mit der Literatur und der qualitativen Forschungsmethodik. Hierzu wurden vier «Kommunikationsexpertinnen» anhand von teilstrukturierten Leitfadeninterviews befragt. Aus den Ergebnissen wird schlussendlich ersichtlich, dass keine negativen Einflüsse von LUG auf die Kommunikationsentwicklung zu befürchten sind. Eher im Gegenteil liefern vereinzelte Studien sowie praktische Erfahrungen Evidenz für sich ergebende Vorteile hinsichtlich der Kommunikation in der Kombination der beiden Modalitäten. Vollendung findet die Ausarbeitung in Form eines Lapbooks, welches den Eltern im Kontext der Heilpädagogischen Früherziehung mithilfe des Akrostichons MUSKEL Handlungsanregungen bietet.

description: This study aimed to determine and compare the prevalence, patterns and factors associated with injury between elite Malaysian able-bodied and para-badminton players. Medical records from July 2007 to December 2017 were reviewed. Among 209 able-bodied players, 1010 injuries were reported. The injuries affected the lower limb (67.2%), sustained during training (94.2%), overuse in nature (38.7%), and involving mostly junior players (62.4%). The injury rate was 94/year, lower than previously reported. Patellar tendinopathy and muscle strain to the upper limb and torso were the commonest. Age, sex and history of injury were predictors of injury. Lower limb injury was a predictor of upper limb and torso injuries, while history of injury to the upper limb and/or torso was a predictor of lower limb injury. Meanwhile, among 18 para-badminton players, 62 injuries were reported from July 2014 to December 2017, which involved the lower limb (45.2%), sustained during training (87.1%), overuse in nature (54.8%), and involved mostly standing-class players (77.8%). The injury rate was 10/year. Patellar tendinopathy, rotator cuff tendinopathy and back muscle strain were the commonest. The patterns of injury (site, occasion and nature) were similar between groups, except for the shoulder where nature was overuse in para-badminton players compared to acute in able-bodied players. All players are susceptible to training-related injuries, particularly to the lower limb. Over the last decade, an increase in the injury index for the lower limb and a shift from chronic to acute for the upper limb were observed among able-bodied players. Age, sex and history of injury expose able-bodied players to greater risk. Meanwhile, for para-badminton players, overuse shoulder and knee injuries are commonest. These findings necessitate a comprehensive injury prevention program that encompasses all body regions with an emphasis on the lower limb among elite Malaysian able-bodied and para-badminton players.

description: Recent developments in the production processes for cubic boron nitride (CBN) abrasive grains have led to commercially available grain sizes larger than lg > 300 µm. These superabrasive grains allow higher material removal rates during grinding of hardened steel components. Currently, these components are pre-machined by turning processes before being hardened and eventually finished by grinding. However, the turning process can be substituted by grinding with coarse CBN-grains since higher depths of cut are achievable when machining hardened components. This paper investigates the process behaviour of vitrified and electroplated grinding wheels with large grain sizes during the machining of hardened steel components. Process forces, wear behaviour and workpiece surface roughness are investigated for three different grain sizes, and the process limits of both bond types are examined. The investigations show that vitrified tools do not fully suit the demands for peel grinding process with high material removal rates since wear by bond breakage occurs. The electroplated tools on the other hand are capable of very high material removal rates. Their wear behaviour is characterized by clogging of the chip space if the process limit is reached. Even so, both tools outperform a standard hard-turning process in terms of process time by 74% and 94% respectively. This process time reduction in combination with the possibility to use the same (machine) tool to machine both soft and hard sections of a workpiece adds flexibility to current process chains.

description: We study the tensor rank of the tensor corresponding to the algebra of n-variate complex polynomials modulo the dth power of each variable. As a result we find a sequence of tensors with a large gap between rank and border rank, and thus a counterexample to a conjecture of Rhodes. At the same time we obtain a new lower bound on the tensor rank of tensor powers of the generalised W-state tensor. In addition, we exactly determine the tensor rank of the tensor cube of the three-party W-state tensor, thus answering a question of Chen et al.

description: A common motivation for studying the cognitive impairments of brain-damaged patients is to determine the “functional architecture” of the cognitive system. But what constitutes a functional architecture? This question used to have a straightforward answer: a set of discrete components with communication pathways among them, with each component assigned a specific function or type of representation. With the additional assumption that brain damage can (and occasionally does) impact individual components or pathways while leaving the rest of the system intact, it becomes possible to use patterns of dissociations in the performance of behavioral tasks by brain-damaged patients to determine the identity and organization of the functional components of the cognitive system (Shallice, 1988).

description: Netball is a physical game with sudden direction changes, decelerations, jumping and landing, stop/start maneuvers and restrictive footwork rules exposing players to injury. Close contact play and shared facilities during tournaments, increase illness risk. Objective: To describe incidence, period prevalence, types and severity of injuries and illnesses during the 10-day Vitality Netball World Cup 2019 (NWC). Methods: All players from 16 teams consented (n = 192). Medical staff recorded injuries (840 exposure hours), illnesses (1440 player-days) and time-loss. Main outcome measures included incidence (I) calculated as injury/1000 player-hours and illness/1000 player-days, period prevalence (PP) and severity (time-loss) of all match injuries and illnesses. 39 players sustained 46 match injuries (I = 54.76; PP = 20.31%). Lower limb injuries (I = 29.76), specifically the ankle (I = 13.10) were most common with lateral ankle ligament sprains the highest (I = 17.39). Contact injuries (I = 40.48) significantly exceeded non-contact injuries (I = 14.29; p = 0.0124). Center players sustained most injuries (n = 12; 26%; I = 14.29), followed by goalkeepers (n = 10; 22%; I = 11.90) and goal defenders (n = 8; 17%; I = 9.52). Injuries occurred in almost 50% of matches, and 67% did not result in time-loss. Time-loss injuries (n = 14; 33%) were most frequent in the lower limb (n = 10; 71%) specifically involved lateral ankle ligaments (n = 4; 29%), attributable to contact (n = 11; 79%) and mostly implicated center players and goal defenders (n = 4 each; 29% each). 11 players contracted 11 illnesses (I = 7.64; PP = 5.72%) with respiratory tract illness contributing 36%. Most illnesses did not result in time-loss (91%). This is the first study reporting injury and illness during an NWC. Contact was the main mechanism of injury, and 2/3 of injuries did not result in time-loss. The ankle is most commonly injured and center players sustain most injuries. Non-respiratory system disease was most frequent, but upper respiratory tract infection remains the most common diagnosis. Targeted surveillance studies using similar methodology are required to develop injury and illness preventative strategies in elite netball.

Genes and behavior in context: moral communities as a source of social control
Creators: name: Freeman, Jason A.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Evidence suggests that individual religiosity reduces the effects of genetic propensities on risky and antisocial behaviors such as delinquency. Yet the moral communities hypothesis suggests that individual religiosity often interacts with contextual religiosity in the prediction of antisocial behaviors. This paper examines interactive patterns involving religiosity at the individual and contextual levels and candidate genes in the prediction of delinquency and number of sexual partners in adolescence. Data come from the genetic subsample of the National Longitudinal Study of Adolescent Health (Add Health). Analyses reveal gene interactions at both the individual level and contextual level. Interactions were found to differ between racial and gender sub-groups. The substantive meanings of these interactions, however, were often inconsistent with the moral communities hypothesis. These empirical results likely reflect an underpowered sample, a limitation that can be addressed with the release of Wave IV DNA data.
Climate Litigation and Atmospheric Ethics: A Case Study of Juliana v. United States

description: This thesis offers an account of climate change lawsuits as ethical experiments which endeavor to develop legal and ethical norms and principles suited to a world remolded by cumulative human actions. It offers a theorization of the ‘what’ and the ‘why’ of the growing, global wave of climate litigation by situating it within the dynamic landscape of contemporary climate politics. Through a case study of Juliana v. United States, a first-of-its-kind constitutional climate lawsuit against the United States federal government, this thesis examines how legal narrative is mobilized to give ethical shape and significance to the problem of climate change and to conceptualize responsibility across vast sweeps of space and time. Interweaving insights from climate ethics, environmental humanities, legal geography and science and technology studies, this research offers a set of meditations on atmospheric ethics

description: Robotic devices for therapy have the potential to enable intensive, fully customized home rehabilitation over extended periods for individuals with stroke and traumatic brain injury, thus empowering them to maximize their functional recovery. For robotic rehabilitation to be most effective, systems must have the capacity to assign performance goals to the user and to increment those goals to encourage performance improvement. Otherwise, individuals may plateau at an artificially low level of function. Frequent goal change is needed to motivate improvements in performance by individuals with brain injury; but because of entrenched habits, these individuals may avoid striving for goals that they perceive as becoming ever more difficult. For this reason, implicit, undetectable goal change (distortion) may be more effective than explicit goal change at optimizing the motor performance of some individuals with brain injury. This paper reviews a body of work that provides a basis for incorporating implicit goal change into a robotic rehabilitation paradigm. This work was conducted with individuals without disability to provide foundational knowledge for using goal change in a robotic environment. In addition, we compare motor performance with goal change to performance with no goal or with a static goal for individuals without brain injury. Our results show that goal change can improve motor performance when participants attend to visual feedback. Building on these preliminary results can lead to more effective robotic paradigms for the rehabilitation of individuals with brain injury, including individuals with cerebral palsy.

description: Within the quantum mechanical treatment of the decay problem one finds that at late times $t$ the survival probability of an unstable state cannot have the form of an exponentially decreasing function of time $t$ but it has an inverse power-like form. This is a general property of unstable states following from basic principles of quantum theory. The consequence of this property is that in the case of false vacuum states the cosmological constant becomes dependent on time: $Λ- Λ_{\text{bare}}\equiv Λ(t) -Λ_{\text{bare}} \sim 1/t^{2}$. We construct the cosmological model with decaying vacuum energy density and matter for solving the cosmological constant problem and the coincidence problem. We show the equivalence of the proposed decaying false vacuum cosmology with the $Λ(t)$ cosmologies (the $Λ(t)$CDM models). The cosmological implications of the model of decaying vacuum energy (dark energy) are discussed. We constrain the parameters of the model with decaying vacuum using astronomical data. For this aim we use the observation of distant supernovae of type Ia, measurements of $H(z)$, BAO, CMB and others. The model analyzed is in good agreement with observation data and explain a small value of the cosmological constant today.

description: Glioblastoma multiforme (GBM) is the most frequent primary malignant tumor of the central nervous system in adults with a mean survival of 12–15 months. An extend of resection (EOR) > 98% of the tumor mass has been associated with an increased overall survival. The aim of our systematic review was to depict the role of advanced image-guided techniques in GBM surgery focusing on their impact on the EOR while preserving the postoperative patients’ quality of life (QoL). Several intraoperative imaging techniques have shown to help during the surgical resec-tion although their limitations must be carefully considered. Combining the use of different in-traoperative tools hold promise in reaching a maximal safe resection while preserving neurologi-cal functions. Multimodal imaging approaches provide better surgical and functional outcomes. However, future tailored studies focusing on neuropsychological assessments are mandatory to better evaluate the link between EOR and QoL.

description: Congenital mirror movements (CMMs) are involuntary, symmetric movements of one hand during the production of voluntary movements with the other. CMMs have been attributed to a range of physiological mechanisms, including excessive ipsilateral projections from each motor cortex to distal extremities. We examined this hypothesis with an individual showing pronounced CMMs. Mirror movements were characterized for a set of hand muscles during a simple contraction task. Transcranial magnetic stimulation (TMS) was then used to map the relative input to each muscle from both motor cortices. Contrary to our expectations, CMMs were most prominent for muscles with the strongest contralateral representation rather than in muscles that were activated by stimulation of either hemisphere. These findings support a bilateral control hypothesis whereby CMMs result from the recruitment of both motor cortices during intended unimanual movements. Consistent with this hypothesis, bilateral motor cortex activity was evident during intended unimanual movements in an fMRI study. To assess the level at which bilateral recruitment occurs, motor cortex excitability during imagined unimanual movements was assessed with TMS. Facilitory excitation was only observed in the contralateral motor cortex. Thus, the bilateral recruitment of the hemispheres for unilateral actions in individuals with CMMs appears to occur during movement execution rather than motor planning.

description: The correlates and consequences of benefit finding on quality of life were examined for 364 women (93% Caucasian, 6% African American, and 1% Hispanic) diagnosed with Stage I, II, and III breast cancer. Benefit finding and quality of life were measured 4 months postdiagnosis (Tl), 3 months after Tl (T2), and 6 months after T2 (T3). Women with lower socioeconomic status, minorities, and those with more severe disease perceived more benefits at baseline. Benefit finding was associated with more negative affect at baseline and also interacted with stage of disease, such that negative relations to quality of life across time were limited to those with more severe disease. Findings suggest there are qualifiers as to whether "finding something good in the bad" is good or bad.

description: Using the mythic Yoruba trickster figure Eshu-legba as a cultural and theoretical guide, I explore two sites of Western identity-play: the phone booth of the superhero icon Superman and the performance stage. This project probes my original script and live production, Authentic Chameleons, which incorporated an adaptation of a Yoruba myth and further extended my research through performance. The topics explored include: the embodiment of mutable identities as a theatrical tradition, the place of multiplicity in cultural performances, and the relationship between performance and identity. Analysis of the production functions to reformulate identity and reconfigure the cultural frameworks that allow for embodied ambivalence and plurality.

description: We study the fidelity decay and its freeze for an initial coherent state of two-mode Bose-Einstein condensates in the Fock regime considering a Bose-Hubbard model that includes two-particle tunneling terms. By using linear-response theory we find scaling properties of the fidelity as a function of the particle number that prove the existence of two-particle mode-exchange when a non-degeneracy condition is fulfilled. Tuning the energy difference of the two modes serves to distinguish the presence of two-particle mode-exchange terms through the appearance of certain singularities. Numerical results confirm our findings. Experimental verification of our findings could improve cold atom interferometry.

We argue that a full understanding of indeterminacy requires the coordination of 3 processes: search, evaluation, and mapping. We describe 3 experiments aimed at discovering the extent to which these processes, each of which has been implicated in previous accounts of indeterminate reasoning, are developed in preschoolers and the extent to which different children organize the processes into different strategies. Experiment 1 examines 5-year-olds' performance on 1- versus 2-solution problems having different configurations of irrelevant information. Experiments 2 and 3 extend the possible sources of indeterminacy from 2 to 4 and vary the amount of consistent, inconsistent, and to-be-discovered evidence. Our results show that 4- and 5-year-old children readily give ''Can tell'' responses to determinate problems, as well as ''Can't tell'' responses when they think that the evidence warrants such a response. In addition, we report 2 new findings: (a) different children use different strategies to process determinate evidence, and these strategies, in turn, predict their performance on indeterminate problems; (b) evidence patterns in which a single positive instance is contrasted with 1 or more negative or unknown instances are particularly difficult to resolve. Many children use a decision rule-the Positive Capture rule-that produces consistent errors on this type of problem.

description: Η αναχαίτιση της πανδημίας Covid-19 συμπεριέλαβε μία σειρά μέτρων, τα οποία είχαν ως αποτέλεσμα την μείωση του εισοδήματος μέρους του πληθυσμού γεγονός, που εικάζεται ότι οδήγησε στην αύξηση των κοινωνικών και οικονομικών ανισοτήτων. Οι παρατεταμένες περίοδοι lockdown εφαρμόστηκαν ως μέτρο περιορισμού της πανδημίας σε όλες τις Ευρωπαϊκές χώρες με διαφορετική αυστηρότητα και διάρκεια. Η παρούσα διπλωματική εργασία έχει ως στόχο την διερεύνηση ύπαρξης κοινωνικών και οικονομιών ανισοτήτων εξαιτίας των μέτρων κατά της πανδημίας στη διάρκεια του πρώτου κύματος και αν οι ανισότητες αυτές είχαν επίπτωση στην χρήση υγειονομικής περίθαλψης και στην υγεία ενός δείγματος ατόμων ηλικίας 50 ετών και άνω. Για τον σκοπό αυτό αξιοποιούνται πληροφορίες από το όγδοο κύμα της πανευρωπαϊκής έρευνας SHARE που αφορά τον Covid-19 (Survey of Health, Ageing and Retirement in Europe). Τα χαρακτηριστικά που εξετάζονται είναι δημογραφικά, κοινωνικά και οικονομικά, καθώς και χαρακτηριστικά σωματικής και ψυχικής υγείας. Στο πρώτο κεφάλαιο παρουσιάζονται γενικές πληροφορίες και ορισμοί που αφορούν την έννοια της κοινωνικοοικονομικής ανισότητας , της νοσηρότητας, της θνησιμότητας, καθώς και την σχέση του κοινωνικού και οικονομικού επιπέδου με το εισόδημα, το μορφωτικό επίπεδο και την υγεία. Στο δεύτερο κεφάλαιο αναλύεται η πανδημία Covid-19 και η σύνδεση αυτής με την όξυνση των κοινωνικοοικονομικών ανισοτήτων όσoν αφορά το εισόδημα και την κοινωνική θέση, εξαιτίας του lockdown που επιβλήθηκε. Για την ανάλυση των δεδομένων της έρευνάς SHARE γίνεται χρήση του στατιστικού πακέτου SPSS. Ειδικότερα, στο τρίτο κεφάλαιο λαμβάνει χώρα η μονοδιάστατη περιγραφική ανάλυση των μεταβλητών ενδιαφέροντος. Στη συνέχεια, στο τέταρτο κεφάλαιο εξετάζεται μέσω της διδιάστατης ανάλυσης αν και σε τι βαθμό σχετίζεται η μεταβολή υγείας, η λήψη ιατρικής περίθαλψης και η μεταβολή τους αισθήματος κατάθλιψης των ερωτηθέντων με δημογραφικούς και κοινωνικοοικονομικούς παράγοντες. Στο πέμπτο κεφάλαιο, πραγματοποιείται περαιτέρω διερεύνηση των τριών μεταβλητών υγείας μέσω μοντέλων διωνυμικής και πολυωνυμικής λογιστικής παλινδρόμησης με σκοπό να αξιολογηθεί η στατιστική σημαντικότητα της επιρροής που ασκούν οι δημογραφικοί και κοινωνικοοικονομικοί παράγοντες σε αυτές. Το έκτο κεφάλαιο αποτελεί την κατακλείδα της παρούσας εργασίας, στο οποίο καταγράφονται τα κυριότερα συμπεράσματα της έρευνας. Πιο συγκεκριμένα, άτομα που έκαναν χρήση των αποταμιεύσεων τους παρουσίασαν χειροτέρευση της υγείας τους σε σχέση με όσους δεν προέβησαν σε αυτή την ενέργεια. Οι γυναίκες παρουσίασαν εντονότερα χειροτέρευση σωματικής και ψυχικής υγείας συγκριτικά με τους άνδρες. Τέλος, σε χώρες της νότιας Ευρώπης οξύνθηκαν περισσότερο οι κοινωνικοοικονομικές ανισότητες στον τομέα της υγείας σε σχέση με χώρες της βόρειας Ευρώπης.

description: Lipoxygenases (LOX) catalyse allylic oxidations and epoxidations of a co-substrate in the presence of an unsaturated fatty acid containing a 1,4-pentadiene moiety. One- and two-step enzyme assays were established to verify the role or involvement of LOX in such co-oxidations. It was shown that LOX is only involved in the formation of reactive hydroperoxides, but not in the oxidation of a co-substrate, assuming a mechanism involving free peroxy radicals for the latter. Ten mono- and sesquiterpenes were used as co-substrates and the resulting products were analysed by mass spectrometry. A semi-preparative approach was developed using (+)-valencene as an example, and the resulting products were isolated by preparative GC and their structures elucidated by NMR spectroscopy.

description: Vehicular wireless channels are highly time-varying and the pilot pattern in the 802.11p orthogonal frequency-division multiplexing frame has been shown to be ill suited for long data packets. The high frame error rate in off-the-shelf chipsets with noniterative receiver configurations is mostly due to the use of outdated channel estimates for equalization. This paper deals with improving the channel estimation in 802.11p systems using a cross layered approach, where known data bits are inserted in the higher layers and a modified receiver makes use of these bits as training data for improved channel estimation. We also describe a noniterative receiver configuration for utilizing the additional training bits and show through simulations that frame error rates close to the case with perfect channel knowledge can be achieved.

description: Abstract: "A parallel distributed processing model is described that learns to comprehend single clause sentences. Specifically, it assigns thematic roles to sentence constituents, disambiguates ambiguous words, instantiates vague words, and elaborates implied roles. The sentences are pre-segmented into constituent phrases. Each constituent is processed in turn to update an evolving representation of the event described by the sentence. The model uses the information derived from each constituent to revise its on-going interpretation of the sentence and to anticipate additional constituents. The network learns to perform these tasks through practice on processing example sentence/event pairs.The learning procedure allows the model to take a long-range statistical approach to solving the bootstrapping problem of learning the syntax and semantics of a language from the same data. The model performs very well on the corpus of sentences on which it was trained, but learns slowly."

description: Recurrence quantification analysis (RQA) is a time-series analysis method that uses autocorrelation properties of typing data to detect regularities within the writing process. The following paper first gives a detailed introduction to RQA and its application to time series data. We then apply RQA to keystroke logging data of first and foreign language writing to illustrate how outcome measures of RQA can be understood as skill-driven constraints on keyboard typing performance. Forty native German students performed two prompted writing assignments, one in German and one in English, a standardized copy task, and a standardized English placement test. We assumed more fluent and skilled writing to reveal more structured typing time series patterns. Accordingly, we expected writing in a well-mastered first language to coincide with higher values in relevant RQA measures as compared to writing in a foreign language. Results of mixed model ANOVAs confirmed our hypothesis. We further observed that RQA measures tend to be higher, thus indicating more structured data, whenever parameters of pause, burst, and revision analyses indicate more fluent writing. Multiple regression analyses revealed that, in addition to typing skills, language proficiency significantly predicts outcomes of RQA. Thus, the present data emphasize RQA being a valuable resource for studying time series data that yields meaningful information about the effort a writer must exert during text production.

description: The visibility of individual scientists and their academic performance plays a major role in gaining the creditability to get funded and to advance in academic positions. Therefore, web presences are increasingly used to boost one’s own visibility, disseminate research results and keep up to date with the research of others. However, previous reports show that these channels are not used equally by all scientists. Our study therefore investigates how faculty members (N = 868) at all universities in Lower Saxony (Germany) in the disciplines of physics, biology and chemistry present themselves on institutional websites and professional networking sites. We find that online presentations on institutional websites are mostly rudimentary. In contrast, there are more informative self-presentations on professional networking sites for both established (professors) and less-established (only PhD holders) faculty members. Our figures confirm observations that scientists present themselves online, but less-established ones seem to find less-supportive environments in academic institutions.
A mechanistic exploration of oil recovery via selective oil permeation

Oil-water separation

description: Oil-water separations are necessary for the reuse of oil-laden wastewater. For example, oil and gas produced water may have influent oil concentrations of up to 2,000 mg/L that must be reduced to <10–35 mg/L to meet regulatory requirements for non-industrial reuse. However, many conventional oil-water separation processes are unable to achieve these effluent concentrations. Selective oil permeation is a promising membrane-based oil-water separation approach that may be able to meet these treatment goals. The process differs from traditional membrane-based oil-water separations by permeating oil (instead of water) through the hydrophobic membrane. Exploitation of the preferential oil wetting of the membrane surface minimizes viscous fouling and generates an oil permeate stream. Previous investigation of selective oil permeation has demonstrated its ability to recover oil over extended durations. Researchers have hypothesized that mechanistic competition between coalescence and permeation controls oil recovery, results in the development of an oil film at the membrane surface, and leads to transport phenomena that deviate from traditional pore flow models. However, further verification is necessary to validate the existence of hypothesized mechanisms within the process and verify its applicability to produced water treatment. Few studies have investigated mechanistic interactions or process performance (i.e., oil flux, oil recovery, permeate quality) for oil concentrations less than 1%. Even fewer have probed relationships between process performance, operating conditions, and water quality characteristics. Understanding the answers to these outstanding questions is crucial to defining the opportunity space for selective oil permeation. This dissertation is the first set of studies to present results that (1) characterize and provide guidance for enhancing the membrane conditioning process, (2) identify how the operative mechanisms are impacted by system characteristics, operating conditions, and water quality characteristics within this lower oil concentration range, and (3) apply selective oil permeation to produced water. Achieving the outlined objectives will both expand our understanding of the role of the two key mechanisms underlying selective oil permeation (coalescence and permeation) and begin to define the opportunity space for oil recovery via selective oil permeation.

description: The entanglement entropy and the logarithmic negativity can be computed in quantum field theory through a method based on the replica limit. Performing these analytic continuations in some cases is beyond our current knowledge, even for simple models. We employ a numerical method based on rational interpolations to extrapolate the entanglement entropy of two disjoint intervals for the conformal field theories given by the free compact boson and the Ising model. The case of three disjoint intervals is studied for the Ising model and the non compact free massless boson. For the latter model, the logarithmic negativity of two disjoint intervals has been also considered. Some of our findings have been checked against existing numerical results obtained from the corresponding lattice models.
