The application of free ammonia inhibition towards partial nitritation in mainstream wastewater treatment
Creators: name: Luo, Yaqian
Publisher: name: University of British Columbia
Year: 2020

description: Partial nitritation/anammox (PN/A) is a novel pathway for nitrogen removal in wastewater treatment that offers advantages of low oxygen and organic carbon demands as well as high potential for energy recovery. However, the partial nitritation process remains a key hurdle for the widespread implementation of the PN-A process in mainstream treatment due to the difficulty in washing out nitrite-oxidizing bacteria (NOB) from active sludge. Exposing biomass to high concentrations of free ammonia (FA) has been reported as an effective strategy to achieve partial nitritation. This study examined the effectiveness of treating 20% of return activated sludge with synthetic centrate containing FA at 200 mg N/L for 24 hours to promote partial nitritation in mainstream wastewater treatment. Experimental and control bioreactors were operated under two different conditions, with or without FA treatment, respectively, after reaching similar nitrification performance. Biokinetic parameters of ammonium-oxidizing bacteria (AOB) and NOB were estimated by performing respirometric batch tests with activated sludge biomass from the two bioreactors under different operational conditions, and calibrating a process model based on oxygen mass balance. The bioreactor performance showed that the FA treatment strategy promoted the PN process, with a maximum nitrite accumulation ratio (NAR) of 41.9 ± 2.1% after treating return sludge with high FA solution for 37 days. However, this nitrite accumulation was not stable, and the NAR decreased to 10.9 ± 6.0% after 33 days, indicating that NOB were able to acclimate to the temporary exposure to a high FA concentration. The biomass yield coefficient (Y) of AOB increased during FA treatment, while the maximum specific growth rate (μmax) of AOB and NOB decreased under this condition. Microbial community analysis on activated sludge under FA treatment, and further investigations on the optimization of the FA treatment strategy combined with other NOB out-selection strategies are required to better facilitate the application of PN-A to full-scale mainstream wastewater treatment.

description: Biosorption is a low cost and environmentally friendly form of bioremediation. It has been found to be effective for removing heavy metals from both soil and water. This study focused on the fungal biosorption of specific heavy metals (Cd, Cr, Cu, As, Pb, and Zn) that are common environmental pollutants, as a means to bioremediate pollutants that can be consequences of rapid urbanization and industrialization. Fungal species were collected from contaminated sites along Waller Creek and their ability to biosorb heavy metals was investigated using ICPMS. Results found that Penicillium spp. from Waller Creek site CS was able to best biosorb Zn (110 g Zn/g fungal dry mass), while also performing well with Cr and Pb (4.6 and 4.0 g/g, respectively) and having detectable levels of As and Cd (0.3 and 0.2 g/g, respectively). Ag and Cu were only detected in single replicates, and so are not reliable datapoints. Limitations include bacterial contamination in original cultures from biomass suspensions, inconsistency in methodology as the procedure writing was an ongoing process and breaks within the fungi incubation process where culture conditions could not be checked on as frequently. Further investigation for other fungal species might be able to provide a deeper understanding on how different fungal characteristics affect their heavy metals bioremediation process and replications with varying concentration of heavy metals standard or performing more repeated runs on the ICPMS are suggested to reduce uncertainties in the data.

description: We study the quench dynamics of the topological quantum phase transition in the two-dimensional transverse Wen-plaquette model, which has a phase transition from a Z2 topologically ordered to a spin-polarized state. By mapping the Wen-plaquette model onto a one-dimensional quantum Ising model, we calculate the expectation value of the plaquette operator Fi during a slowly quenching process from a topologically ordered state. A logarithmic scaling law of quench dynamics near the quantum phase transition is found, which is analogous to the well-known static critical behavior of the specific heat in the one-dimensional quantum Ising model.

description: We consider the problem of discretization for the U(1)-invariant nonlinear wave equations in any dimension. We show that the classical finite-difference scheme used by Strauss and Vazquez \cite{MR0503140} conserves the positive-definite discrete analog of the energy if the grid ratio is $dt/dx\le 1/\sqrt{n}$, where $dt$ and $dx$ are the mesh sizes of the time and space variables and $n$ is the spatial dimension. We also show that if the grid ratio is $dt/dx=1/\sqrt{n}$, then there is the discrete analog of the charge which is conserved. We prove the existence and uniqueness of solutions to the discrete Cauchy problem. We use the energy conservation to obtain the a priori bounds for finite energy solutions, thus showing that the Strauss -- Vazquez finite-difference scheme for the nonlinear Klein-Gordon equation with positive nonlinear term in the Hamiltonian is conditionally stable.

description: Genderkompetenz ist zu einem wichtigen Schlagwort moderner Hochschulpolitik geworden. Neben den weitreichenden Gleichstellungsmaßnahmen, die in den letzten Jahren an vielen Universitäten eingeführt wurden, ist eine umfassende genderdidaktische Weiterbildung der Lehrenden an Universitäten ein wichtiger, bislang vergleichsweise wenig beachteter Baustein in diesem Prozess. Der Aufsatz diskutiert, welchen Beitrag genderdidaktische Maßnahmen für mehr Sensibilität und methodische Kompetenz des wissenschaftlichen Personals an Hochschulen und für ein Mehr an moderner Wissenschaftskultur leisten können. Dazu zählen vor allem die Sensibilisierung für die Erweiterung des Curriculums um genderrelevante Aspekte, ein bewusster Umgang mit Sprache und Bildern in der Lehre sowie eine unter dem Aspekt der Genderproblematik reflektierte Unterrichtsmethodik.

description: Human herpesviruses 6A and 6B are betaherpesviruses that can integrate their genomes into the telomeres of latently infected cells. Integration can also occur in germ cells, resulting in individuals who harbor the integrated virus in every cell of their body and can pass it on to their offspring. This condition is termed inherited chromosomally integrated HHV-6 (iciHHV-6) and affects about 1% of the human population. The integrated HHV-6A/B genome can reactivate in iciHHV-6 patients and in rare cases can also cause severe diseases including encephalitis and graft-versus-host disease. Until now, it has remained impossible to prevent virus reactivation or remove the integrated virus genome. Therefore, we developed a system that allows the removal of HHV-6A from the host telomeres using the CRISPR/Cas9 system. We used specific guide RNAs (gRNAs) targeting the direct repeat region at the ends of the viral genome to remove the virus from latently infected cells generated in vitro and iciHHV-6A patient cells. Fluorescence-activated cell sorting (FACS), quantitative PCR (qPCR), and fluorescence in situ hybridization (FISH) analyses revealed that the virus genome was efficiently excised and lost in most cells. Efficient excision was achieved with both constitutive and transient expression of Cas9. In addition, reverse transcription-qPCR (RT-qPCR) revealed that the virus genome did not reactivate upon excision. Taken together, our data show that our CRISPR/Cas9 approach allows efficient removal of the integrated virus genome from host telomeres.

description: The progressively rising food-borne Campylobacter jejuni infections pose serious health problems and socioeconomic burdens. Given that antibiotic therapy is not recommended for most campylobacteriosis patients, novel treatment options include strategies targeting iron homeostasis that impacts both C. jejuni virulence and inflammatory cell damage caused by toxic oxygen species. In our preclinical intervention study, we tested potential disease-alleviating effects upon prophylactic oral application of the iron-chelating compound desferoxamine (DESF) in acute murine campylobacteriosis. Therefore, microbiota-depleted IL-10(-/-) mice received synthetic DESF via the drinking water starting seven days before oral infection with C. jejuni strain 81-176. Results revealed that the DESF application did not reduce gastrointestinal pathogen loads but significantly improved the clinical outcome of infected mice at day 6 post-infection. This was accompanied by less pronounced colonic epithelial cell apoptosis, attenuated accumulation of neutrophils in the infected large intestines and abolished intestinal IFN-gamma and even systemic MCP-1 secretion. In conclusion, our study highlights the applied murine campylobacteriosis model as suitable for investigating the role of iron in C. jejuni infection in vivo as demonstrated by the disease-alleviating effects of specific iron binding by oral DESF application in acute C. jejuni induced enterocolitis.

description: Palliative care adds significant burdens to healthcare workers. In neuropalliative care (NPC), additional challenges include patient symptom burdens, such as impairments in mobility, cognition, and communication. After one year of operating the first NPC ward in Germany, we assessed burdens, resources, and the number of deaths perceived as stressful. NPC physicians and nursing staff were compared with the team of other neurological wards, including a stroke unit. The assessment took place between March 2022 and May 2022. All 64 team members were contacted; the responder rate was 81%. The perceived burden was high but did not differ between groups. There were no differences between the NPC- and the neurological wards in the number of deaths perceived as stressful. However, rather than the number of deaths, the circumstances of dying influence the perceived distress. The resources mentioned were similar between groups, with the team and private life being most important. Communication difficulties were frequently cited as stressful, whereas successful communication was identified as a resource.

description: This work is motivated by the work of Kim et al (2008), which considered the equation of state parameter for the new agegraphic dark energy based on generalized uncertainty principle coexisting with dark matter without interaction. In this work, we have considered the same dark energy inter- acting with dark matter in emergent, intermediate and logamediate scenarios of the universe. Also, we have investigated the statefinder, kerk and lerk parameters in all three scenarios under this inter- action. The energy density and pressure for the new agegraphic dark energy based on generalized uncertainty principle have been calculated and their behaviors have been investigated. The evolu- tion of the equation of state parameter has been analyzed in the interacting and non-interacting situations in all the three scenarios. The graphical analysis shows that the dark energy behaves like quintessence era for logamediate expansion and phantom era for emergent and intermediate expansions of the universe.

description: We show that a short-time regime, in which a deviation from the exponential decay law occurs, exists also in the framework of a superrenormalizable relativistic quantum field theory. This, in turn, implies the possibility of a quantum Zeno effect also for elementary decays. The attention is then focused on the typical order of magnitude of strong decay rates of mesons: for these particles, strong deviations from the exponential decay law are present during a period of time comparable with their mean life time. As a concrete example, the case of the $ρ$ meson is studied.

description: Against the background of a society that tends to underrate the grief experienced by parents whose infants have died prematurely, the model "SORROWFUL" is presented here with the intent to highlight the significance of the death of a newborn for the affected family. It is a supportive tool in counseling for parents grieving the (impending) loss of an infant(s) during peri- or neonatal life and may be implemented within the parental psychosocial support setting beginning with the initial diagnosis until well after the death of the child. The model intentionally allows flexibility for cultural and individual adaptation, for the accommodation to the varying needs of the affected parents, as well as to available local resources.

description: Recently it has been shown that when the Dark Matter (DM) particles captured in the Sun directly annihilate into neutrino pairs, the oscillatory terms in the oscillation probability do not average to zero and can lead to a seasonal variation as the distance between the Sun and Earth changes in time. In this paper, we explore this feature as a novel method to extract information on the properties of dark matter. We show that by studying the variation of the flux over a few months, it would in principle be possible to derive the DM mass as well as new information on the flavor structure of the DM annihilation modes. In addition to analytic analysis, we present the results of our numerical calculations that take into account scattering and regeneration of neutrinos traversing the Sun.

description: Objective: The objective of this study was to deliver an intervention to improve health awareness for infection prevention, hygiene, and sanitation to assess its impact. Furthermore, it aimed to identify the risk of multimorbidity in women of reproductive years from low socio-economic background. Methods: A randomized control trial was conducted in Pakistan among women aged 15–45 years. Overall, 820 women participated in the baseline survey; 388 women were part of the control group and 360 of the intervention group. A digital health literacy intervention was delivered by 91 trained community health workers. Data were analyzed using descriptive statistics and multivariate logistic regression. Results: About 35.9% of women suffered from multimorbidity. The intervention group showed higher odds of confidence in managing health with respect to skill and technique acquisition (AOR = 2.21; 95% CI 1.01–4.84), self-monitoring and insight (AOR = 2.97; 95% CI 1.29–6.80) as well as sanitation and hygiene (AOR = 1.42; 95% CI 1.07–1.93). Two primary outcomes related to hand hygiene and protective behavior against infection did not show any significant improvement. The secondary outcomes of the study related to impact on overall health-related quality of life, social integration and support, and emotional well-being also did not show any significant improvement. Conclusions: Digital health literacy interventions and multimorbidity management for women of reproductive years at the primary level are a way forward to alleviate communicable and non-communicable disease burden in developing countries like Pakistan. These efforts are also critical to improve maternal and child health in developing regions.

description: INTRODUCTION: Prone positioning ventilation (PPV) is an effective treatment for patients with moderate to severe acute respiratory distress syndrome (ARDS). Despite the benefits of PPV, different kinds of short and long-term consequences have been noted. This review summarizes long-term complications of PPV that impact treatment strategies and outcomes in acute and postacute rehabilitation. EVIDENCE ACQUISITION: PubMed/Medline, Cochrane Library, Cochrane COVID-19 Study Register databases and the Google Scholar search engine were systematically searched for studies investigating long-term complications of PPV. The final search date for all sources/databases was January 31, 2022. For our methodological appraisal, we conducted a systematic review of articles without any restrictions on types of articles or publication dates. Only articles published in English and available as full texts were eligible for inclusion. After the screening process, data of interest were extracted from eligible sources: PPV sequelae and conclusions (i.e. possible effects on the course of rehabilitation and therapy strategies). EVIDENCE SYNTHESIS: A total of 59 studies are included in this review. Long-term consequences are mainly pressure ulcers and nerve lesions that exist after discharge from the Intensive Care Unit (ICU). Publications rarely recommend treatment strategies for long-term complications after PPV. Due to the quality of the included studies, no robust conclusions as to effective strategies can be drawn. CONCLUSIONS: Further high-quality research is required, considering the different long-term complications after PPV and their impact on rehabilitation in order to draw conclusions about viable physical therapies. Crucially, however, prone positioning (PP) sequelae pose new challenges to physicians and therapists in acute and postacute rehabilitation medicine as well as follow-up care.

description: Das Forschungsprojekt untersuchte den Wirkungsgrad verschiedener mineralischer Mörtel, mit und ohne Armierungsmaterial, als Schutzüberzüge (Opferputze) bewitterter Architekturoberflächen und Wandmalereien. Die Überprüfung der korrekten Anbindung der Schutzüberdeckungen und die systematische Nachkontrolle von Maßnahmen sind aus Sicht der Denkmalpflege zwingend erforderlich, da Umwelteinflüsse wie Erschütterungen, die z. B. durch Straßenverkehr verursacht werden auftreten können. Darüber hinaus können extreme Klimaschwankungen durch Sonneneinstrahlung, Kälteeinbrüche oder Frost zu thermisch beeinflussten Ausdehnungen führen. In deren Folge kommt es zur Bewegung und Ablösungen innerhalb von einfachen oder mehrlagigen Putzsystemen. Der Anwendungsbezug lag in diesem Projekt auf der Entwicklung und Überprüfung von Schutzüberzügen sowie der Beurteilung ihre Einsetzbarkeit und Effizienz, exemplarisch an einer Pilotfläche der Westfassade an den römischen Fassadenmalereien des Weltkulturerbes Konstantinbasilika Trier. Ziel des Forschungsprojektes war es, mineralische Schutzputzsysteme zu konzipieren und diese auf ihre Anbindung und Wirkungsgrad hin mittels der sogenannten Terahertz-Zeitbereichsspektroskopie (THz-TDS1) zu untersuchen. Die THz-TDS kann als neuartige, zerstörungsfreie und berührungslose Messtechnik zur tiefenaufgelösten Diagnostik denkmalgeschützter Kulturgüter genutzt werden. Hiermit können auch kleinste Ablösungen zwischen Mörtelsystemen und originalen Oberflächen methodisch exakt detektiert werden. Der Erfolg der angestrebten Schutzmaßnahmen kann somit langfristig überprüft und dokumentiert werden. Zudem wurden die konzipierten Mörtel durch physikalische Untersuchungen (Feuchtegehalt und Rohdichte, Wasseraufnahme und -abgabe, Wasserdampfdiffusionswiderstand, dynamischer E-Modul, Feuchte- und Wärmedehnung, Haftzugfestigkeit, Alterung etc.) auf ihre Qualität und Dauerhaftigkeit hin überprüft.

description: Previous far-infrared observations at low-angular resolution have reported the presence of water associated with low-velocity outflow shocks and protostellar envelopes. The outflow driven by the intermediate-mass class 0 protostar Cep E is among the most luminous outflows detected so far. Using the IRAM 30m telescope, we searched for and detected the para-water line emission at 183 GHz in the Cep E star-forming core. The emission arises from high-velocity gas close to the protostar, which is unresolved in the main beam of the telescope. Complementary observations at 2" resolution with the Plateau de Bure interferometer helped establish the origin of the emission detected and the physical conditions in the emitting gas. The water line profile and its spatial distribution are very similar to those of SiO. We find that the water emission arises from warm ($\sim 200\K$), dense ($(1-2)\times 10^6\cmmt$) gas, and its abundance is enhanced by one to two orders of magnitude with respect to the protostellar envelope. We detect water emission in strong shocks from the high-velocity jet at 1000 AU from the protostar. Despite the large beam size of the telescope, such emission should be detectable with Herschel.

description: We show that the differences between correlators of the critical O(N) vector model in three dimensions and those of the free theory are precisely accounted for by the change of boundary condition on the bulk scalar of the dual higher spin gauge theory in AdS4. Thus, the conjectured duality between Vasiliev's theory and the critical O(N) model follows, order by order in 1/N, from the duality with free field theory on the boundary.

description: The observations in many applications consist of counts of discrete events, such as photons hitting a detector, which cannot be effectively modeled using an additive bounded or Gaussian noise model, and instead require a Poisson noise model. As a result, accurate reconstruction of a spatially or temporally distributed phenomenon (f*) from Poisson data (y) cannot be effectively accomplished by minimizing a conventional penalized least-squares objective function. The problem addressed in this paper is the estimation of f* from y in an inverse problem setting, where (a) the number of unknowns may potentially be larger than the number of observations and (b) f* admits a sparse approximation. The optimization formulation considered in this paper uses a penalized negative Poisson log-likelihood objective function with nonnegativity constraints (since Poisson intensities are naturally nonnegative). In particular, the proposed approach incorporates key ideas of using separable quadratic approximations to the objective function at each iteration and penalization terms related to l1 norms of coefficient vectors, total variation seminorms, and partition-based multiscale estimation methods.

Novel few-layer black phosphorus nanostructure fabrication methods and DFT simulations
Creators: name: Liu, Teren
Publisher: name: University of British Columbia
Year: 2020

description: This paper reports the successful fabrication of large size few-layer black phosphorus, and nano-patterning of 2-dimensional black phosphorus by a top-down lithography and etching approach. The wet etching process can etch selected regions of few-layer black phosphorous with an atomic layer accuracy. This etch method is deep-UV and e-beam lithography process compatible, and is free of oxygen and other common doping sources. 10 nm deep BP trenches were successfully fabricated. Density function theory (DFT) simulations proved that that the etching is bond-breaking-driven instead of intercalation-driven. It provides a feasible patterning approach for large-scale manufacturing of few-layer BP materials and devices. The wet etching method was applied to fabricate twisted-stacked BP with the interface as a Moiré pattern. DFT was used to simulate the phonon vibrations and Raman spectra of the Moiré pattern. Our DFT results indicate that a novel interlayer interaction may exist in this kind of structures. Experimental work by Tao Fang confirmed the simulation results.

description: Biallelic variants in the kaptin gene KPTN were identified recently in individuals with a novel syndrome referred to as autosomal recessive intellectual developmental disorder 41 (MRT41). MRT41 is characterized by developmental delay, predominantly in language development, behavioral abnormalities, and epilepsy. Only about 15 affected individuals have been described in the literature, all with primary or secondary macrocephaly. Using exome sequencing, we identified three different biallelic variants in KPTN in five affected individuals from three unrelated families. In total, two KPTN variants were already reported as a loss of function variants. A novel splice site variant in KPTN was detected in two unrelated families of this study. The core phenotype with neurodevelopment delay was present in all patients. However, macrocephaly was not present in at least one patient. In total, two patients exhibited developmental and epileptic encephalopathies with generalized tonic-clonic seizures that were drug-resistant in one of them. Thus, we further delineate the KPTN-related syndrome, especially emphasizing the severity of epilepsy phenotypes and difficulties in treatment in patients of our cohort.
Large Scale Structures in Kinetic Gravity Braiding Model That Can Be Unbraided

description: We study cosmological consequences of a kinetic gravity braiding model, which is proposed as an alternative to the dark energy model. The kinetic braiding model we study is characterized by a parameter n, which corresponds to the original galileon cosmological model for n=1. We find that the background expansion of the universe of the kinetic braiding model is the same as the Dvali-Turner's model, which reduces to that of the standard cold dark matter model with a cosmological constant (LCDM model) for n equal to infinity. We also find that the evolution of the linear cosmological perturbation in the kinetic braiding model reduces to that of the LCDM model for n=\infty. Then, we focus our study on the growth history of the linear density perturbation as well as the spherical collapse in the nonlinear regime of the density perturbations, which might be important in order to distinguish between the kinetic braiding model and the LCDM model when n is finite. The theoretical prediction for the large scale structure is confronted with the multipole power spectrum of the luminous red galaxy sample of the Sloan Digital Sky survey. We also discuss future prospects of constraining the kinetic braiding model using a future redshift survey like the WFMOS/SuMIRe PFS survey as well as the cluster redshift distribution in the South Pole Telescope survey.

description: In the context of the low energy effective theory, the exact Landau level spectrum of quasiparticles in twisted bilayer graphene with small twist angle is analytically obtained by spheroidal eigenvalues. We analyze the dependence of the Landau levels on the twist angle to find the points, where the two-fold degeneracy for twist angles is lifted in the nonzero modes and below/above which massive/massless fermion pictures become valid. In the perpendicular magnetic field of 10\,T, the degeneracy is removed at $θ_{\rm deg}\sim 3^\circ$ %angles around 3 degrees for a few low levels, specifically, $θ_{\rm deg}\simeq 2.56^\circ$ for the first pair of nonzero levels and $θ_{\rm deg}\simeq 3.50^\circ$ for the next pair. Massive quasiparticle appears at $θ

C10403 - Ottimizzazione di rivestimenti fotocatalitici in Titania
Creators: name: Cottone Palumbo, Giulio
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2021

description: Lo studio eseguito è atto alla caratterizzazione del processo di rivestimento di un lattice in Allumina (Al2O3) tramite il metodo dell’immersione. Il materiale depositato è Titania (TiO2) in polvere nanometrica Degussa P25. Il manufatto finale sarà poi atto alla disinfezione dell’aria tramite la fotocatalisi. Nella prima parte del lavoro si analizza il procedimento di immersione per la realizzazione di rivestimenti in Titania, andando nel cuore dei processi fisici che lo governano, al fine di capire con esattezza quali siano i passaggi principali e critici. Si esegue poi un’analisi della letteratura per capire i parametri utilizzati negli altri studi. In seguito, si realizza una sperimentazione atta ad amplificare il comportamento reologico della sospensione di base. Si passa poi alla stesura, analisi ed esecuzione di un piano sperimentale DOE, il quale permette di capire le influenze dei parametri di processo sul rivestimento finale, spiegandole dopo un ulteriore studio della letteratura. Nella seconda parte, queste tendenze e l’analisi di dati ulteriori permettono di effettuare due sperimentazioni mirate all’identificazione di un rivestimento ottimo. Con la prima di queste si elimina l’effetto della gravità durante l’asciugatura e si identifica quale dei passaggi possa essere il più critico per la formazione di difetti superficiali; per fare ciò, si indaga sul motivo di questi avvenimenti dando possibili soluzioni. In un secondo momento si va a verificare se il passaggio identificato sia effettivamente quello critico. Alla fine dello studio si ottiene un rivestimento capace di sopportare le condizioni d’uso senza perdita di massa e con uno spessore ed un guadagno in peso adeguati. Inoltre, si danno possibili soluzioni per raggiungere coperture senza difetti.
