Can the Acoustical Particle Sizing Device be Used for Fog Droplet Counting and Sizing?
Creators: name: Singh, Devendra Pal
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1988

description: The acoustical particle sizing device was evaluated for counting and sizing of fog droplets. Fog droplets were generated under controlled conditions in the laboratory, and measurements for the fog droplet counts were made at different flow rates (5.7 to 14.2 liters/minute). Most of the droplets were found to be in the size range of 5-30 μm. The Reynolds number was calculated by reference to the flow rates. Fog droplet sizes were measured with optical and electron microscopes and correlated with a standard curve of particle threshold diameter versus critical flow Reynolds number. The mean diameters estimated by using the standard curve were in agreement with the microscope values of mean droplet diameter. A Rich 100 Condensation Nuclei monitor was also operated simultaneously during the droplet counting by the acoustical particle sizing device, to monitor condensation nuclei counts in the laboratory. The results indicated that the condensation nuclei number in the laboratory correlate with the fog droplet threshold diameters. Aerosols of a uniform size (35 microns) were generated by the vibrating orifice monodisperse aerosol generator and counted at three different flow rates by the acoustical particle sizing device. The counts/liter/minute were similar, indicating the reliability of the acoustical particle sizing device. Key Words: Acoustical particle sizing device, condensation nuclei, fog droplets, particle size distribution.

Tentative Identification of Organic Compounds in the Influent and Effluent of the High Point Westside Wastewater Treatment Plant and Implications for Aquatic Toxicity
Creators: name: Storm, Julia F.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1987

description: After identifying an acute toxicity problem, the North Carolina Division of Environmental Management required the High Point Westside Wastewater Treatment Plant (WWTP) to institute periodic biomonitoring and reduce the toxicity. Here, Westside WWTP samples are analyzed using the chemical-specific approach to toxicity reduction in which potential toxicants are identified. WWTP samples determined as "toxic" or "nontoxic" by Daphnia pulex bioassay, effluents from six categories of industrial dischargers, and a domestic wastewater sample are analyzed for organic chemicals using continuous solvent extraction of wastewater samples and broad spectrum GC/MS analysis. An extensive database is developed which includes aquatic toxicity data and tentatively identified compounds in WWTP samples and industrial effluents ranked according to their potential for contribution to toxicity. The study suggests that many compounds found in Westside WWTP influent and effluent are of industrial origin since they occur inboth industrial samples and Westside WWTP samples. Treatment does not remove some organic compounds exhibiting significant toxicity to aquatic organisms and shown to be present in "toxic" effluents and industrial samples. Toxicity of Westside WWTP influent and effluent may be caused by a variety of industrial organic compounds in concentrations that alone would not be sufficient to produce a toxic effect but, because they may all produce toxicity by the same mechanism (narcosis) and thus may exhibit concentration addition, together produce a toxic effect. Recommendations for further analyses include confirmation of identifications using additional mass spectral techniques and determination of estimated or empirical aquatic toxicities.

description: We define the $\textit{Divisor Divisibility Sequence}$ associated to a Laurent polynomial $f\in\mathbb{Z}[X_1^{\pm1},\ldots,X_N^{\pm1}]$ to be the sequence $W_n(f)=\prod f(ζ_1,\ldots,ζ_N)$, where $ζ_1,\ldots,ζ_N$ range over all $n$'th roots of unity with $f(ζ_1,\ldots,ζ_N)\ne0$. More generally, we define $W_Λ(f)$ analogously for any finite subgroup $Λ\subset(\mathbb C^*)^N$. We investigate divisibility, factorization, and growth properties of $W_Λ(f)$ as a function of $Λ$. In particular, we give the complete factorization of $W_Λ(f)$ when $f$ has generic coefficients, and we prove an analytic estimate showing that the rank-of-apparition sets for $W_Λ(f)$ are not too large.

Creators: name: Merkle, Edgar C.
name: Rosseel, Yves
Publisher: name: arXiv
Year: 2015
Subjects: subject: Computation (stat.CO)
subject: FOS: Computer and information sciences

description: This article describes blavaan, an R package for estimating Bayesian structural equation models (SEMs) via JAGS and for summarizing the results. It also describes a novel parameter expansion approach for estimating specific types of models with residual covariances, which facilitates estimation of these models in JAGS. The methodology and software are intended to provide users with a general means of estimating Bayesian SEMs, both classical and novel, in a straightforward fashion. Users can estimate Bayesian versions of classical SEMs with lavaan syntax, they can obtain state-of-the-art Bayesian fit measures associated with the models, and they can export JAGS code to modify the SEMs as desired. These features and more are illustrated by example, and the parameter expansion approach is explained in detail.

Evaluation of Magnetic Ion Exchange (MIEX) Pre-treatment on Ozonation Performance and Disinfection By-Product Formation
Creators: name: Kingsbury, Ryan S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: The purpose of this research was to investigate the performance of treatment with magnetic ion exchange (MIEX) resin followed by ozonation of waters from the San Francisco Bay Delta in achieving disinfection goals while controlling bromate and chlorinated disinfection by-product (DBP) formation. Three water samples were collected from raw water supplies impacted by the Delta to represent the varying levels of bromide and organic carbon that occur throughout the year. A fourth water was prepared by spiking bromide and chloride into a portion of one of the samples. Jar testing with alum and MIEX resin was conducted to determine optimal doses for total organic carbon (TOC) and (in the case of MIEX resin) bromide removal. Samples of each water were treated with alum or MIEX resin, and the raw and treated waters were subsequently ozonated under semi-batch conditions to assess the impact of treatment on ozone demand, ozone exposure for disinfection ("CT"), and bromate formation. Finally, aliquots of raw, coagulated, resin-treated, and ozonated waters were chlorinated in order to measure trihalomethane formation potential (THMFP). In the waters studied, MIEX resin removed 41-68% of raw water TOC, compared to 12-44% for alum. MIEX resin also reduced the bromide concentration by 20-50%. The removal of TOC by alum and MIEX resin significantly reduced the ozone demand of all waters studied, resulting in higher dissolved ozone concentrations and CT values for a given amount of ozone transferred into solution. For a given level of disinfection (CT), the amount of bromate produced by ozonation of MIEX-treated waters was similar to or slightly less than that of raw water. MIEX resin removed 39-85% of THMFP compared to 16-56%removal by alum. Ozonation reduced THMFP by 35-45% in all cases. This work indicates that in bromide-rich waters in which ozone disinfection is used, MIEX resin is a more appropriate treatment than alum for the removal of organic carbon, as it achieves superior TOC and THM precursor removal and decreases the production of bromate.

description: Obwohl eine Beforschung des Neonatizids auch im Hinblick auf grundlegende Aspekte, wie beispielsweise Fallaufkommen oder Deliktphänomenologie, lohnend scheint, ist die Idee zu vorliegender Untersuchung in erster Linie aus einem kriminalistischen Interesse aus der Ermittlungspraxis entstanden: Anlässlich einer ungeklärten Neugeborenentötung im Mai 2005 erkundigte sich das Polizeipräsidium (PP) Krefeld beim Landeskriminalamt Nordrhein-Westfalen (LKA NRW) nach wissenschaftlichen oder polizeilichen Erkennt-nissen über die Verteilung von Tat- und Täterinnenmerkmalen beim Neonatizid, um dadurch die Auswahl und Durch-führung der Ermittlungsmaßnahmen in diesem aktuellen Fall zu optimieren. Dabei ging es insbesondere um die Priorisierung von Auswahlkriterien für DNA-Reihenuntersuchungen. Eine Sichtung des nationalen und internationalen Forschungsstandes brachte nur wenige kriminalistisch verwertbare Erkenntnisse hervor. Aus diesem Grund konzipierten das Sachgebiet „Operative Fallanalyse“ (OFA) und die „Kriminalistisch-Kriminologische Forschungsstelle“ (KKF) des LKA NRW eine Auswertung von einschlägigen Fallakten. Im vorliegenden Bericht werden keine Aussagen zur Nützlichkeit des neuen Gesetzes zur vertraulichen Geburt (Abschnitt 6, §§ 25-34 Schwangerschaftskonfliktgesetz (SchKG)), zu Babyklappen, anonymen Geburten oder Übergaben (siehe hierzu allgemein Deutscher Ethikrat 2009, Coutinho/Krell 2012) oder vergleichbaren Angeboten getroffen. Derartigen Maßnahmen wird gelegentlich eine präventive Wirkung in Bezug auf den Neonatizid unterstellt (hierzu siehe beispielsweise Küch 2011 und kritisch Rohde 2007); eine empirische Prüfung dieser Annahme ist allgeimein als schwer möglich zu beurteilen (vgl. Klier et al. 2012) und war nicht Gegenstand der vorliegenden Studie. Vielmehr sollen die Ergebnisse der Studie den ermittelnden Polizeibeamtinnen und -beamten in zukünftigen Fällen von Neonatizid ein vertieftes Wissen zur Deliktphänomenologie zur Verfügung stellen. Zudem kann existierenden Mythen (beispielsweise in Bezug auf ein überwiegend jugendliches Alter, erstgebärende Kindsmütter) um das Deliktsfeld Neonatizid (vgl. beispielsweise Krüger 2009, Höynck/Zähringer/ Behnsen 2012) der Nährboden entzogen werden. Neben der Optimierung der Ermittlungs- und Fahndungsmaßnahmen sollen dadurch auch die beteiligten Vernehmungsbeamtinnen und -beamten in die Lage versetzt werden, ihr Gegenüber (i. d. R. die Kindsmütter) besser einschätzen und damit zielgerichteter befragen zu können.

description: For a family of geometric objects in the plane $\mathcal{F}=\{S_1,\ldots,S_n\}$, define $χ(\mathcal{F})$ as the least integer $\ell$ such that the elements of $\mathcal{F}$ can be colored with $\ell$ colors, in such a way that any two intersecting objects have distinct colors. When $\mathcal{F}$ is a set of pseudo-disks that may only intersect on their boundaries, and such that any point of the plane is contained in at most $k$ pseudo-disks, it can be proven that $χ(\mathcal{F})\le 3k/2 + o(k)$ since the problem is equivalent to cyclic coloring of plane graphs. In this paper, we study the same problem when pseudo-disks are replaced by a family $\mathcal{F}$ of pseudo-segments (a.k.a. strings) that do not cross. In other words, any two strings of $\mathcal{F}$ are only allowed to "touch" each other. Such a family is said to be $k$-touching if no point of the plane is contained in more than $k$ elements of $\mathcal{F}$. We give bounds on $χ(\mathcal{F})$ as a function of $k$, and in particular we show that $k$-touching segments can be colored with $k+5$ colors. This partially answers a question of Hliněný (1998) on the chromatic number of contact systems of strings.

description: Pre-registration for in-lab and mTurk experiments based off of pilot data. In this long-term memory experiment, subjects will be tasked with learning the colors for hundreds of objects. Unknown to subjects, the regularity at which colors for these objects are sampled will be biased. Specifically, 40% of objects will be colored according to a constrained portion of a color wheel. We hypothesize that these statistical regularities during encoding may systematically distort the later retrieval of object colors during a testing phase in which subjects are asked to use a continuous color report to select the original color for each object.

Die Befragung fand wiederholt mit jeweils unterschiedlichen Teilnehmern statt. Die Auswahl der Personen erfolgte nach einem Zufallsprinzip, sodass die Ergebnisse für die Bevölkerung in NRW verallgemeinert werden können. Insgesamt wurden in drei Befragungswellen ca. 20 000 Personen befragt. Durch diese große Anzahl konnten aussagekräftige Ergebnisse erzielt werden. Die Ergebnisse geben Auskunft über Taten, die der Polizei bekannt wurden, aber auch solche, die nicht angezeigt wurden. Tätliche Angriffe – Was genau wurde dazu gefragt? Wer wird Opfer und wer nicht? Geleitet wurde diese Frage von der Suche nach Risikofaktoren zur Opferwerdung. Nicht jedes Opfer zeigt den tätlichen Angriff bei der Polizei an. Warum nicht? Was kann die Polizei besser machen? Die Anzeigenerstatter wurden zu ihrer Zufriedenheit mit der polizeilichen Arbeit gefragt. Ergebnisse – Was haben die Bürgerinnen und Bürger berichtet? Es wird nicht schlimmer! Die Entwicklung der Fallzahlen ist stabil, tendenziell sogar rückläufig. Die meisten Opfer tätlicher Angriffe sind jung und männlich. Alte Menschen haben in NRW das geringste Risiko Opfer zu werden. Je schwerer die Tat, desto eher wird eine Anzeige erstattet. Überraschend viele Opfer bewerten den tätlichen Angriff nicht als Straftat. Die Opfer sind mit der polizeilichen Arbeit generell zufrieden. Bei Taten mit Verletzungsfolgen kann die Polizei besser werden.

Investigation of Hepatic Enzyme Systems Ability to Catalyze the DNA Binding of 3-Nitrofluoranthene and 2-Nitrofluoranthene
Creators: name: Bojes, Heidi Katharina
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: 3-Nitrofluoranthene (3-NFA) and 2-Nitrofluoranthene are environmental pollutants created during combustion processes, proven to be mutagenic in bacterial assays and potentially carcinogenic in mammalian species. The binding of electrophilic metabolites of a nitro-PAH to DNA may lead to mutagenicity and carcinogenicity. This study shows that rat hepatic enzyme systems in S9 are able to catalyze the binding of 3-NFA (labeled with [14]C) and 2-NFA (labeled with [3]H) to calf thymus DNA in vitro. Maximum activity (800-1500 pmole 3-NFA/mg DNA in 1 hour) for 3-NFA occurred in incubations conducted under air and with S9 and NADPH. When NADH was used as a cofactor less activity was obtained (200-500 pmole 3-NFA/mg DNA in 1 hour). The converse held true for 2-NFA as greatest activity occurred under air and with S9 but with NADH (1.1-1.25 pmole 2-NFA/mg DNA in 1 hour). DNA-bound radioactivity was less with NADPH in similar conditions (0.6-0.8 pmole 2-NFA/mg DNA in 1 hour). Addition of other cofactors (FAD and FMN in addition to NAD and NADPH) showed insignificant levels of binding for either isomer. SKF 525A was unable to inhibit DNA binding of both compounds. Addition of glutathione had no effect in incubations with 3-NFA but seem to enhance the DNA binding of 2-NFA. These results indicate the participation of cytochrome P-450 in the oxidative metabolism of 3-NFA and possibly 2-NFA.

description: We introduce $L^2$-Betti numbers, as well as a general homology and cohomology theory for the standard invariants of subfactors, through the associated quasi-regular symmetric enveloping inclusion of II_1 factors. We actually develop a (co)homology theory for arbitrary quasi-regular inclusions of von Neumann algebras. For crossed products by countable groups $Γ$, we recover the ordinary (co)homology of $Γ$. For Cartan subalgebras, we recover Gaboriau's $L^2$-Betti numbers for the associated equivalence relation. In this common framework, we prove that the $L^2$-Betti numbers vanish for amenable inclusions and we give cohomological characterizations of property (T), the Haagerup property and amenability. We compute the $L^2$-Betti numbers for the standard invariants of the Temperley-Lieb-Jones subfactors and of the Fuss-Catalan subfactors, as well as for free products and tensor products.

Discovering Social Groups via Latent Structure Learning

Publisher: name: Open Science Framework
Year: 2022

description: Humans form social coalitions in every society on earth, yet we know very little about how social group boundaries are learned and represented—especially in the absence of overt labels or visual cues to individuals’ group membership. Here we adopt a computational model of latent structure learning to move beyond explicit category labels and mere similarity as the sole inputs to social group representations, and to formalize an alternative process by which people create group representations. Four experiments examine (i) how evidence for group boundaries is accumulated in a consequential social context (i.e., learning about others’ political values); (ii) to what extent learning about these boundaries drives one’s own preferences and behavior as well as attributions about other agents in the environment; and (iii) whether these latent groups affect choice even in the presence of group labels that contradict the latent group structure. In contrast to models where social groups are learned solely via matching to group labels/stereotypes or dyadic similarity to the self, our results suggest that people integrate information about how agents in the environment relate to one another in addition to oneself to infer a posterior distribution over possible latent groupings.

Adapting Constructed Wetlands Treatment of Domestic Wastewater for New Reuse Applications
Creators: name: Komaravolu, Vaishnavi
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Wetlands, whether constructed or manmade, have been widely used in wastewater treatment methods as they are efficient water purification systems and nutrient sinks. A constructed wetland is a sustainable and environmental friendly option for the treatment of domestic wastewater because it is affordable, reliable, easy to operate and offers control over design and operating conditions at the point of wastewater generation. It can be designed to remove total suspended solids, pathogens, heavy metals, organic pollutants and reduce oxygen demand of the treated water and has been demonstrated to remove pharmaceuticals and personal care products with comparable efficiencies to that of conventional wastewater treatment plants. However, the land requirements and high water retention times often make the treatment process slow. This report suggests engineering modifications to an existing system at Jordan Lake Business Park that would potentially improve the effectiveness of the constructed wetland in removal of traditional pollutants and pharmaceutical compounds with the purpose of directly using the treated effluent for agricultural land applications.

description: This paper considers continuous-time block-monotone Markov chains (BMMCs) and their block-augmented truncations. We first introduce the block monotonicity and block-wise dominance relation for continuous-time Markov chains, and then provide some fundamental results on the two notions. Using these results, we show that the stationary distribution vectors obtained by the block-augmented truncation converge to the stationary distribution vector of the original BMMC. We also show that the last-column-block-augmented truncation (LC-block-augmented truncation) provides the best (in a certain sense) approximation to the stationary distribution vector of a BMMC among all the block-augmented truncations. Furthermore, we present computable upper bounds for the total variation distance between the stationary distribution vectors of a Markov chain and its LC-block-augmented truncation, under the assumption that the original Markov chain itself may not be block-monotone but is block-wise dominated by a BMMC with exponential ergodicity. Finally, we apply the obtained bounds to a queue with a batch Markovian arrival process and state-dependent departure rates.

A Method for Dilute Mixing of Reactants in an Outdoor Aerosol Chamber and the Application to an α-pinene/Ozone System
Creators: name: Wilson, Rebecca Leigh

Year: 2008

description: Atmospheric aerosols have received increasing attention within the past few years as their role in global climate change is investigated. However, it remains difficult to capture and quantify nucleation events at ambient concentrations in a smog chamber setting. A novel method was developed to mix two dilute reactants at near-ambient concentrations. This method was tested using at the UNC 270m^3 Outdoor Aerosol Chamber in Pittsboro, NC with a dark α-pinene/ozone system at near-ambient concentrations. These results were compared against the UNC Particle Mechanism and scientific literature to test the validity of the method. Further experiments were conducted to examine the role water vapor and background ammonium sulfate seed have in aiding or inhibiting nucleation events.

description: EPA's list of recommended default concentrations, from the Guideline for Regulatory Application of the Urban Airshed Model, were substituted for SAI's AIRQUALITY, BOUNDARY, and TOP CONC files In the Atlanta 5-cities PLANR approach study. These concentrations were also substituted for the ROM (Regional Oxidant Model) derived AIRQUALITY, BOUNDARY and TOP CONC files in the ROM/UAM interface test case for the New York domain. In the case of Atlanta, where the differences between the original and default values were small, the peak concentrations each hour were within a few ppb of each other and domain-wide there were only changes of 10 to 15 ppb in the concentration contours. However, both runs miss the peak measured concentration by one-half. The default input concentrations were usually less than half of the ROM derived ones in the New York domain. Here there is a large decrease in the model output of ozone, up to 80 ppb near the southern boundary and 50 to 60 ppb in the area of maximum concentrations. Even with these large decreases,the difference between the UAM/ROM output concentrations and the observed ozone concentrations are greater than the difference between the UAM/ROM and the default run forecast concentrations of ozone.
Controlling Agricultural Nonpoint Source Nutrient Pollution Through Nutrient Trading and Wetland Buffers: Tar-Pamlico, North Carolina Case Study

Year: 1994

description: The ability of the lead nonpoint source control agency to satisfy the requirements of the Tar-Pamlico nutrient management plan and some important issues influencing nutrient trading with nonpoint sources are examined. Research revealed the agency is not currently equipped to quantify nutrient reductions and does not have effective control technologies for removing soluble nitrogen from agricultural runoff. Recommendations are made for steps which should be taken in order to assure nonpoint source reductions are achieved and goals attained in Phase 11 of the plan. The use of restored wetland buffers as a potential nitrogen control mechanism in the Tar-Pamlico basin is also investigated. Ecological research on the soluble nitrogen removal capabilities of existing wetland buffers is utilized to support a proposed implementation and management framework for the adoption of riparian and headwater wetlands as nutrient controls. The framework is designed in accordance with selected environmental criteria and estimates of nitrogen removal per unit area of wetland are provided.

description: The appearance of the light Higgs boson at the LHC is difficult to explain, particularly in light of naturalness arguments in quantum field theory. However light scalars can appear in condensed matter systems when parameters (like the amount of doping) are tuned to a critical point. At zero temperature these quantum critical points are directly analogous to the finely tuned standard model. In this paper we explore a class of models with a Higgs near a quantum critical point that exhibits non-mean-field behavior. We discuss the parametrization of the effects of a Higgs emerging from such a critical point in terms of form factors, and present two simple realistic scenarios based on either generalized free fields or a 5D dual in AdS space. For both of these models we consider the processes $gg\to ZZ$ and $gg\to hh$, which can be used to gain information about the Higgs scaling dimension and IR transition scale from the experimental data.

An Analytic Expression of Relative Approximation Error for a Class of Evolutionary Algorithms
Creators: name: He, Jun
Publisher: name: arXiv
Year: 2015
Subjects: subject: Neural and Evolutionary Computing (cs.NE)

description: An important question in evolutionary computation is how good solutions evolutionary algorithms can produce. This paper aims to provide an analytic analysis of solution quality in terms of the relative approximation error, which is defined by the error between 1 and the approximation ratio of the solution found by an evolutionary algorithm. Since evolutionary algorithms are iterative methods, the relative approximation error is a function of generations. With the help of matrix analysis, it is possible to obtain an exact expression of such a function. In this paper, an analytic expression for calculating the relative approximation error is presented for a class of evolutionary algorithms, that is, (1+1) strictly elitist evolution algorithms. Furthermore, analytic expressions of the fitness value and the average convergence rate in each generation are also derived for this class of evolutionary algorithms. The approach is promising, and it can be extended to non-elitist or population-based algorithms too.

description: Die vorliegende Arbeit befasst sich mit den Nutzungsmotiven von TinderuserInnen. Den Anstoß zu dem Thema liefern verschiedene Studien, die meist von Elisabeth Timmermans und ihren ForschungskollegInnen veröffentlich wurden. Die Studien behandeln die Nutzung und die Nutzungsmotive von Tinder. Ihre Tinder Motives Scala (TMS) sollte aus diesem Grund von einer neuen Seite beleuchtet und mittels 17 Leitfadeninterviews geprüft bzw. ergänzt werden. Nach einer computergestützten Auswertung mittels MAXQDA kann folgendes ergänzt werden: TinderuserInnen verknüpfen ihr Instagram oder geben ihren Instagramnamen an, damit sie mehr Reichweite auf dieser App bekommen können. Zusätzlich wird Tinder genutzt, um an neuen Wohnorten Freundschaften schließen zu können. Der Hauptgrund Tinder zu nutzen, ist die Möglichkeit viele neue Leute aus einem anderen Umfeld kennenzulernen und das auch in Zeiten der COVID-19 Pandemie. Hinzufügend ist herausgefunden worden, dass Frauen vor allem mit Tinder ihr Selbstwertgefühl aufwerten, während Männer lockere Beziehungen suchen. In Hinblick auf das Wohlbefinden zeigt sich, dass sich die App großteils positiv auf das Wohlbefinden auswirkt und nur bei wenigen InterviewpartnerInnen negative Emotionen auslöst. Bei einer zu intensiven Nutzung kann eine Sucht entwickelt werden, da man von der positiven Bestärkung durch Matches abhängig wird.
description: The thesis deals with the existing usage motives of Tinder users. Various studies, most of them published by Elisabeth Timmermans and her research colleagues, provided the impetus for the topic. The studies deal with the use and motives for using Tinder. Therefore, the Tinder Motives Scala (TMS) should be illuminated from a new perspective or supplemented by using 17 guided interviews. After a computer-aided evaluation using MAXQDA, the results are the following: Tinder users link their Instagram or share their Instagram name to generate reach on this app. In addition, Tinder is used to make friends in new places. The main reason to use Tinder is the opportunity to meet many new people from different environments, even in times of the COVID-19 pandemic. Moreover, it has been found that women in particular use Tinder to boost their self-esteem, while men seek casual relationships. As far as well-being is concerned, it is likely that the app has a largely positive effect on well-being and only triggers negative emotions in a few interviewees. If overused, an obsession can be developed as one becomes dependent on positive reinforcement from matches.

description: The divergent series for a function defined through Lapalce integral and the ground state energy of the quartic anharmonic oscillator to large orders are studied to test the generalized binomial transform which is the renamed version of $δ$-expansion proposed recently. We show that, by the use of the generalized binomial transform, the values of functions in the limit of zero of an argument is approximately computable from the series expansion around the infinity of the same argument. In the Laplace integral, we investigate the subject in detail with the aid of Mellin transform. In the anharmonic oscillator, we compute the strong coupling limit of the ground state energy and also the expansion coefficients at strong coupling from the weak coupling perturbation series. The obtained result is compared with that of the linear delta expansion.

description: Eight months after a 2018 earthquake in Haiti, citizens in the Artibonite watershed began to present symptoms of cholera. At the height of the outbreak in late October a hospital is handling 400 patients presenting with cholera. In an effort to curb the spread of cholera in the region, a solar waste pasteurizer was designed to treat the liquid waste from the patients in the cholera clinics. The solar pasteurization heats the liquid to 55°C and has a retention time of half an hour after exiting the pipe system to ensure proper inactivation of the vibrio cholera.
