Evaluation of an educational campaign to improve adherence to pneumatic compression devices: impact of a quality improvement initiative
Creators: name: Patel, Dhara S.
Publisher: name: No Publisher Supplied
Year: 2021

description: Background: Venous thromboembolism (VTE) is a condition associated with significant levels of morbidity, disability, and mortality among hospitalized and ambulatory patients. Given its impact on individuals' health and the costs of treating complications associated with VTE, this preventable condition is now considered a global health concern. Pneumatic compression devices play a critical role in the prevention of VTE. Purpose: The purpose of this 6 -week quality improvement project was to evaluate an educational campaign to improve adherence to pneumatic compression devices by exploring whether the use of a bedside visual cue would impact adherence to the use of pneumatic compression devices. Methods: A bedside sign served as a visual cue for patients to use pneumatic compression devices, and a series of educational in-services on VTE prevention were conducted for nursing staff on a medical surgical unit at an academic medical center. Weekly audits of patient adherence to pneumatic compression devices were done to assess change in adherence over time.Results: Findings showed that staff education combined with the use of visual cues was associated with an increase in patient adherence with pneumatic compression devices. Average compliance to pneumatic compression devices increased from 85% to 89.6% over the 6-week observation period. Implications: The use of visual cues, combined with education is an important intervention in the prevention and management of VTE.
Community radio: guidelines on how to record and broadcast communities' meetings
Creators: name: Cibin, Roberto

Publisher: name: Zenodo
Year: 2019

description: Guidelines for broadcasting community meetings for Web and mobile access were developed and integrated into the project Website. The preferred option is that all meetings about the station are aired live on the station as they happen. Secondarily, RootIO provides features that allow for the recordings of meetings to be aired, as well as synthesizing audio from minutes of meetings. After various discussions with the project partners, including those more involved in community outreach, the focus went on strengthening the possibilities of using voice and telephone in the assembly processes of decision-making. For this reason, a tutorial on how to use RootIO for this goal was designed, focused on showing how to broadcast an assembly and how to allow people to take part in it through the use of the telephone. This solution offers the possibility of involving as many people as possible in the decision-making process, avoiding the digital divide, directly addressing one of the focal issues of community governance. The aim of these guidelines was to offer a simple and clear tool to the communities that could guide them in two main tasks: the recording and broadcasting of public events through the use of a phone and the RootIO technology and the retrieval of this material and publication of some excerpts. The live broadcasting of the community radio stations’ meetings can also support the achievement of other social outcomes. This operation places focus on the importance of transparent assembly decision-making processes that can be heard by the entire community. The opportunity to intervene during the assemblies through a simple phone call increases the possibility of people’s participation in the discussion. This document is the result of mock-ups for mobile and desktop designed.

description: The densest state of matter in the universe is uniquely realized inside central cores of the neutron star. While first-principles evaluation of the equation of state of such matter remains as one of the longstanding problems in nuclear theory, evaluation in light of neutron star phenomenology is feasible. Here we show results from a novel theoretical technique to utilize deep neural network with supervised learning. We input up-to-date observational data from neutron star X-ray radiations into the trained neural network and estimate a relation between the pressure and the mass density. Our results are consistent with extrapolation from the conventional nuclear models and the experimental bound on the tidal deformability inferred from gravitational wave observation.

Human Factors : Can we learn from avalanche incidents and apply the findings to tailings and mine waste?
Creators: name: Philip, Lucy

description: Year in, year out, experienced and qualified groups succumb to avalanche hazard, despite advances in equipment and technology. Unfortunately, and sometimes tragically, these groups learn lessons the hard way. What leads to the decisions that these groups make, that ultimately turn out to be poor decisions? Are there any lessons for tailings and waste management? How do our tailings and management systems stand up if we take those lessons learned into mine waste management? Perhaps, more importantly, can we avoid the same pitfalls and issues when it comes to making risk decisions for our facilities? This paper presents several ideas and terms from avalanche incidents and learnings and places them in the context of tailings and mine waste. These ideas and terms include: judgement; group decision making; speaking up; accountability in group decision making, termed social facilitation; familiarity, which is a form of complacency; social pressures, such as acceptance; and the expert halo. Current guidelines for tailings management systems and roles and responsibilities are audited and evaluated against the learnings and findings from avalanche events and a reality check presented. Finally, some author thoughts and recommendations are provided. This paper is intended to open eyes to learnings from other sorts of safety incidents and raise some ideas. The paper may pose more questions than provide answers.

description: The purpose of this study was to document the development and implementation of student-coached chamber ensembles within a traditional orchestra setting where students took on roles as chamber music coaches to facilitate student chamber ensemble rehearsals in the preparation of performance. With traditional large ensembles that emphasize whole-group performance dominating secondary music education, there is a lack of empirically based evidence that clarifies procedures for developing high school chamber music programs while working within time constraints of a typical high school music program. This research provides educators with clarity on how to practically incorporate chamber ensemble opportunities in the music classroom. Additionally, the issues of how participation in student-coached chamber ensembles may contribute to musical and social development in areas of creativity, critical thinking, communication, and collaboration for student coaches and players were explored. Fifteen students in my high school orchestra ensemble volunteered to partake in this study. Three student coaches in grades 11-12, and twelve student players in grade 9, were formed into three ensembles and selected as the focus for this study. Data were collected from January to June 2019, in a high school located in a small suburban town about 25 miles outside a major US city, and consisted of multiple sources of evidence: rehearsal reflection summaries, video recordings of rehearsals and performances, individual and focus group interviews using a video-stimulated recall method, a teacher journal, and additional artifacts. Findings from a qualitative analysis revealed that participation in student-coached chamber ensembles appears to contribute to musical and social development in areas of creativity, critical thinking, communication, and collaboration for both student coaches and players. In addition to these skills, positive social relationships were formed, students improved in playing more independently, a greater sense of individual responsibility and levels of self-confidence increased, and skills acquired from this experience translated to other areas. This experience allowed students an opportunity for more active engagement in the rehearsal process and choice in repertoire, and as the teacher-researcher, gaps in my own instruction emerged. Results from this study show that student-coached chamber ensembles can positively impact students’ learning experiences and teacher instruction.

description: In this article, we discuss the outcomes of an experiment where we analysed whether and to what extent the introduction, in 2012, of the new research assessment exercise in Italy (a.k.a. Italian Scientific Habilitation) affected self-citation behaviours in the Italian research community. The Italian Scientific Habilitation attests to the scientific maturity of researchers and in Italy, as in many other countries, is a requirement for accessing to a professorship. To this end, we obtained from ScienceDirect 35,673 articles published from 1957 and 2016 by the participants to the 2012 Italian Scientific Habilitation, that resulted in the extraction of 1,379,050 citations retrieved through Semantic Publishing technologies. Our analysis showed an overall increment in author self-citations (i.e. where the citing article and the cited article share at least one author) in several of the 24 academic disciplines considered. However, we depicted a stronger causal relation between such increment and the rules introduced by the 2012 Italian Scientific Habilitation in 10 out of 24 disciplines analysed.
Instantons and Saturation in the Colour Dipole Picture

description: We pursue the intriguing possibility that larger-size instantons build up diffractive scattering, with the marked instanton-size scale $ \approx 0.5$ fm being reflected in the conspicuous ``geometrization'' of soft QCD. As an explicit illustration, the known instanton contribution to DIS is transformed into the intuitive colour dipole picture. With the help of lattice results, the $q \bar{q}$-dipole size r is carefully increased towards hadronic dimensions. Unlike pQCD, one now observes a competition between two crucial length scales: the dipole size r and the size $ρ$ of the background instanton that is sharply localized around $ \approx 0.5$ fm. For r exceeding $$, the dipole cross section indeed saturates towards a geometrical limit, proportional to the area $π^2$, subtended by the instanton.

Three Convolution Inequalities on the Real Line with Connections to Additive Combinatorics

description: We discuss three convolution inequalities that are connected to additive combinatorics. Cloninger and the second author showed that for nonnegative $f \in L^1(-1/4, 1/4)$, $$ \max_{-1/2 \leq t \leq 1/2} \int_{\mathbb{R}}{f(t-x) f(x) dx} \geq 1.28 \left( \int_{-1/4}^{1/4}{f(x) dx}\right)^2$$ which is related to $g-$Sidon sets (1.28 cannot be replaced by 1.52). We prove a dual statement, related to difference bases, and show that for $f \in L^1(\mathbb{R})$, $$ \min_{0 \leq t \leq 1}\int_{\mathbb{R}}{f(x) f(x+t) dx} \leq 0.42 \|f\|_{L^1}^2,$$ where the constant 1/2 is trivial, 0.42 cannot be replaced by 0.37. This suggests a natural conjecture about the asymptotic structure of $g-$difference bases. Finally, we show for all functions $f \in L^1(\mathbb{R}) \cap L^2(\mathbb{R})$, $$ \int_{-\frac{1}{2}}^{\frac{1}{2}}{ \int_{\mathbb{R}}{f(x) f(x+t) dx}dt} \leq 0.91 \|f\|_{L^1}\|f\|_{L^2}$$

description: We study a dynamical system with time dependent Hamiltonian by numerical experiments so as to find a relation between thermodynamics and chaotic nature of the system. Excess information loss, defined newly based on Lyapunov analysis, is related to the increment of thermodynamic entropy. Our numerical results suggest that the positivity of entropy increment is expressed by the principle of the minimum excess information loss.

description: The Centers for Disease Control and Prevention proposes that universities/colleges implement comprehensive sexual violence prevention programming (SV-PP). Data suggest intimate partner violence (IPV) exceeds campus sexual violence (SV) rates with rape culture (RC) creating an environment conduce to SV; with limited information on graduate students’ SV and IPV experiences. To improve university/college SV-PP, counseling, and mental health services for all students, studies of IPV and SV, and a contributing factor, RC, are needed. This dissertation is a secondary data analysis of the American College Health Association-National College Health Assessment IIc comparing responses from Spring 2016 to Spring 2019 to illuminate the relationship between IPV and SV. Specific aims were to: 1) explore the relationship between IPV and SV amongst students; 2) compare IPV and SV experiences between undergraduate and graduate students; and, 3) develop an instrument assessing students’ RC perceptions. Analyses (SPSS Version 26) illustrated that SV was correlated (2016: r=.25, p

Fix a subset V of Z^d, and a (large) N such that calling G_{N,V} the set of contours of length at least N intersecting V, there are in average one contour in G_{N,V} under the infinite volume "plus" measure. We find bounds on the total variation distance between the law of the contours of lenght at least N intersecting V under the "plus" measure and a Poisson process. The proof builds on the Chen-Stein method as presented by Arratia, Goldstein and Gordon. The control of the correlations is obtained through the loss-network space-time representation of contours due to Fernandez, Ferrari and Garcia.

Leptogenesis, mass hierarchies and low energy parameters

Publisher: name: arXiv
Year: 2002
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Leptogenesis in a left-right symmetric model is investigated for all possible neutrino mass hierarchies. The predictions of the model for low energy parameters as measured in neutrinoless double beta decay and in oscillation experiments are compared. The preferred values of the Majorana phases and limits on the smallest mass state are given. The main observation is that for the inverse hierarchy observable CP violation in oscillation experiments as well as a sizable signal in neutrinoless double beta decay can be expected. In a degenerate scheme, one Majorana phase is bounded to be around pi/2 or pi, and this ambiguity can easily be tested through neutrinoless double beta decay. The dependence of the baryon asymmetry on the different "Dirac" and "Majorana" phases is analyzed and a possibility to avoid the gravitino problem is discussed.

Student-Teacher relationships as predictors of reading comprehension gains in 2nd grade

Publisher: name: Columbia University

Subjects: subject: Psychology
subject: FOS: Psychology

description: The purpose of this study was to examine whether the perceived quality of the student-teacher relationship in second grade predicted reading comprehension gains over the course of one year in a model that included variables known to effect reading comprehension: quality of classroom instruction, social economic status, engagement, and peer relatedness. Reading comprehension gains for 255 second grade students in a high socio-economic school district were obtained in a pre-post fashion from school records over a single academic year. Teachers' rated each student in their class on one occasion in terms of the degree of conflict and closeness in the student-teacher relationship, the quality of peer relatedness, and classroom engagement. The CLASS (Pianta, Paro, & Hamre, 2008), an observation system, was employed to measure several important classroom variables including emotional support, classroom organization, and instructional support, yielding a teacher competence score. Because the 255 students were nested within seven different elementary schools with 14 different teachers, a hierarchical linear model (HLM) was used with classroom engagement as a mediating variable. There were an insufficient number of teachers and elementary schools to use HLM so an alternative model that estimated the overall relationships among the variables and corrected the significance tests for the nesting of the students within classrooms, and the nesting of the classrooms (teachers) within schools was employed. The hypothesized model fit the data well (÷2 = 9.17, (4), p < .06, RMSEA = .07, CFI = .98). Significant direct paths were found for student-teacher closeness, peer relatedness, and fall reading scores on classroom engagement. Significant indirect paths were found from student-teacher closeness, peer relatedness, and fall reading scores to reading comprehension gains via classroom engagement. Finally, classroom engagement had a positive direct effect on reading comprehension. Teacher competence and conflict in student-teacher relations were unrelated to reading comprehension gains. Study findings have implications for future educational focus such as improving classroom engagement, fostering close student-teacher-relationships, enhancing peer relatedness, and training teachers. Future research should be conducted with larger and more diverse samples, and examine the student's perception of the student-teacher relationship.
KeV scale new fermion from a hidden sector

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We studied a simple model of hidden sector consists of a Dirac fermion $χ$ and a spontaneously broken $U(1)_s$ symmetry. The dark sector is connected to the Standard Model(SM) via three righthanded SM singlet neutrinos, $N_R$'s, and the kinetic mixing between $U(1)_s$ and $U(1)_Y$. A mixing between the scalar $ϕ$ that breaks $U(1)_s$ and the SM Higgs boson, $H$, is implemented via the term $ϕ^\dagger ϕH^\dagger H$ and this provides a third connection to the SM. Integrating out the $N_R$ at a high scale not only gives the active neutrinos, $ν$, masses but generates effective Dirac type of couplings between $ν$ and $χ$. This changes the usual Type-I seesaw results for active neutrino masses and makes $χ$ behave like a sterile neutrino even though its origin is in the hidden sector. $χ$ is also split into a pair of Majorana fermions. The amount of splitting depends on the parameters. If the lighter of the pair has a mass around keV, its lifetime is longer than the age of the universe and it can be a warm dark matter candidate. Signatures of $χ$ in high precision Kurie plots of nuclei $β$ decays and low energy neutrino nuclei coherent scatterings are discussed. The model also induces new invisible $Z$ decay modes that can be searched for in future Z factories.

Student-centered instruction and math and science achievement in the post-Soviet state: a mixed methods analysis

Publisher: name: Columbia University
Year: 2012
Subjects: Education and state

description: This dissertation examines the relationship between the use of student-centered instructional methods in teaching mathematics and science, and achievement of fourth graders in these subjects. The context for analyzing this relationship is the post-Soviet region, with Kazakhstan selected as the main focus of the study, and the object of its in-depth qualitative case analysis. The measures of student-centered instructional methods are drawn from student surveys administered as part of the 2007 TIMSS study, while the TIMSS test scores serve as measures of student achievement. The quantitative analysis finds that student-centered instructional methods generally show no statistically significant relationship with student achievement across all country datasets included in this analysis. The qualitative case study follows up on these results in the context of Kazakhstan, and finds that while student-centered instruction is hailed as the pathway to reform of education in this post-Soviet country, the state lacks the capacity to engage in instructional reform and improvement of teacher quality, while the teachers look to the state to guide them in choosing the right instructional methods. As a result, instructional transformations take place in highly haphazard, heterogeneous ways, while teachers require direction, guidance, and support from the central state to effectively implement student-centered methods in their lessons.

Much like opsins are activated by light, enlightenment on Open Science was the aim of the PhD Event at the Department of Molecular Bioscience, Wenner-Gren Institute, (MBW) on Friday, May 3, 2019. “Open Science” reads like a tautology – a redundant use of words. Being that science strives to expand and spread knowledge, it should be open at its core. However, the system in which science is currently conducted is not set up to do so openly, i.e. transparently. In order to shed some light on the specific problem areas, the MBW PhD students wanted to raise awareness about the ideas of Open Science.

The document is a collection of the slides presented by the invited speakers Sofie Wennström, Niclas Jareborg, Gustav Nilsonne, Anna Wetterbom and Wilhelm Widmark.

description: In this paper, we discuss a simple model for a field driven, thermostated random walk that is constructed by a suitable generalization of a multi-baker map. The map is a usual multi-baker, but perturbed by a thermostated external field that has many of the properties of the fields used in systems with Gaussian thermostats. For small values of the driving field, the map is hyperbolic and has a unique SRB measure that we solve analytically to first order in the field parameter. We then compute the positive and negative Lyapunov exponents to second order and discuss their relation to the transport properties. For higher values of the parameter, this system becomes non-hyperbolic and posseses an attractive fixed point.

description: The field of dental medical education is one of the most rapidly evolving fields in education. Newer teaching methods are being evaluated and incorporated in dental institutions. One of the promising new methods is the blended learning approach that may involve a “flipped” instructional sequencing, where online instruction precedes the group meeting, allowing for more sophisticated learning through discussion and critical thinking. The author conducted a mixed method, experimental study that focused on second year dental students’ perceptions of blended learning and its effectiveness.
      A sample size of 40 dental students in their second year from a Northeastern Regional Dental School were invited to participate in this study to evaluate a blended learning approach in comparison to a more traditional lecture format. Students who participated in the study, participated in group problem-solving, responded to Likert-type surveys, completed content exams, and were interviewed individually. Based on Likert survey data and interview responses, the participants in the blended learning treatment reported very positive opinions including positive perceptions of the organization, support of meaningful learning and potential merits for use in dental education. There also was evidence that the blended learning group achieved at least as well as the traditional lecture group, and excelled on certain content test items. The results of this study support the conclusion that blended instruction promotes active, in-depth and self-regulated learning. During blended learning, students set standards or goals regarding their learning, evaluate their progress toward these goals, and then adapt and regulate their cognition, motivation, and behavior in order to accomplish their goals. Overall, the results of this research on blended learning, including the use of problem-based learning in group discussions, supports the merits of incorporating blended earning in dental education curricula.

description: We define gauge theories whose gauge group includes charge conjugation as well as standard $\mathrm{SU}(N)$ transformations. When combined, these transformations form a novel type of group with a semidirect product structure. For $N$ even, we show that there are exactly two possible such groups which we dub $\widetilde{\mathrm{SU}}(N)_{\mathrm{I,II}}$. We construct the transformation rules for the fundamental and adjoint representations, allowing us to explicitly build four-dimensional $\mathcal{N}=2$ supersymmetric gauge theories based on $\widetilde{\mathrm{SU}}(N)_{\mathrm{I,II}}$ and understand from first principles their global symmetry. We compute the Haar measure on the groups, which allows us to quantitatively study the operator content in protected sectors by means of the superconformal index. In particular, we find that both types of $\widetilde{\mathrm{SU}}(N)_{\mathrm{I,II}}$ groups lead to non-freely generated Coulomb branches.

description: The purposes of this parallel convergent parallel mixed methods study were to (a) explore the changes in relationship satisfaction for couples participating in the Real Intimacy and Growth Skills (RINGS) Experience; and (b) to explore the individual experiences of the participants in this relationship education program related to how and why their level of relationship education has changed as a result of participating in the program. For this study, fifteen couples were selected at random to participate in the RINGS Experience. Collection of the quantitative data was done using the Couples Satisfaction Index 32-question instrument as a pre-test and post-test. A paired t-test was performed to evaluate changes in relationship satisfaction from the pre-test to the post-test. Semi-structured interviews with four couples were conducted to obtain their opinions, perceptions, and feelings about the RINGS Experience. The results of this study suggest that relationship satisfaction changes from before participating in the RINGS Experience to after the program was completed.

description: The canonical theory of (N=1) supergravity, with a matrix representation for the gravitino covector-spinor, is applied to the Bianchi class A spatially homogeneous cosmologies. The full Lorentz constraint and its implications for the wave function of the universe are analyzed in detail. We found that in this model no physical states other than the trivial "rest frame" type occur.

Highly tunable nonlinear Hall effects induced by spin-orbit couplings in strained polar transition-metal dichalcogenides

description: Recently, signatures of nonlinear Hall effects induced by Berry-curvature dipoles have been found in atomically thin 1T'/Td-WTe$_2$. In this work, we show that in strained polar transition-metal dichalcogenides(TMDs) with 2H-structures, Berry-curvature dipoles created by spin degrees of freedom lead to strong nonlinear Hall effects. Under an easily accessible uniaxial strain of order 0.2%, strong nonlinear Hall signals, characterized by a Berry-curvature dipole on the order of 1Å, arise in electron-doped polar TMDs such as MoSSe, and this is easily detectable experimentally. Moreover, the magnitude and sign of the nonlinear Hall current can be easily tuned by electric gating and strain. These properties can be used to distinguish nonlinear Hall effects from classical mechanisms such as ratchet effects. Importantly, our system provides a potential scheme for building electrically switchable energy-harvesting rectifiers.

description: A nonlinear equation in a Banach space is written as a linear equation with a linear operator depending on the unknown solution. This method, which we call a global linearization method, differs essentially from the local linearization methods of the Newton-type. Inverting the above linear operator by the methods known for linear operators one gets an equation which sometimes is much better for numerical solution than the original one. Some theorems about convergence of the proposed iterative process for solving the transformed equation are given. Examples of applications are considered.

description: Localized states universally appear when a periodic potential is perturbed by defects or terminated at its surface. In this Letter, we theoretically and experimentally demonstrate a mechanism that generates localized states through continuous translational deformations of periodic potentials. We provide a rigorous proof of the emergence of the localized states under the deformations. The mechanism is experimentally verified in microwave photonic crystals. We also demonstrate topological phase windings of reflected waves for translated photonic crystals.

description: The bottleneck pileup in the energy spectrum is investigated for several two-dimensional (2D) turbulence systems by numerical simulation using high-order diffusion terms to amplify the effect, which is weak for normal diffusion. For 2D magnetohydrodynamic (MHD) turbulence, 2D electron MHD (EMHD) turbulence and 2D thermal convection, which all exhibit direct energy cascades, a nonlocal behavior is found resulting in a logarithmic enhancement of the spectrum.

description: Following a minisuperspace approach to the dynamics of a spherically symmetric shell, a reduced Lagrangian for the radial degree of freedom is derived directly from the Einstein-Hilbert action. The key feature of this new Lagrangian is its invariance under time reparametrization. Indeed, all classical and quantum dynamics is encoded in the Hamiltonian constraint that follows from that invariance. Thus, at the classical level, we show that the Hamiltonian constraint reproduces, in a simple gauge, Israel's matching condition which governs the evolution of the shell. In the quantum case, the vanishing of the Hamiltonian (in a weak sense), is interpreted as the Wheeler-DeWitt equation for the physical states, in analogy to the corresponding case in quantum cosmology. Using this equation, quantum tunneling through the classical barrier is then investigated in the WKB approximation, and the connection to vacuum decay is elucidated.

description: Als der "junge Gelehrte" Lessing, der 1741-46 in der Fürstenschule zu Meissen, 1746-48 in Leipzig an der Universität den Plautus kennengelernt hatte, in Berlin mit C. Mylius die "Beyträge zur Historie und Aufnahme des Theaters" (das erste Heft erschien Ende 1749) begann, glaubte er, das deutsche Theater, und da insbesondere die Komödie bessern und ihr aufhelfen zu können; er glaubte, in den Captivi des Plautus ein Modell für die Art von Komödie gefunden zu haben, die ihm vorschwebte: eine Verbindung von Heiterkeit, lautem Lachen und moralischer Besserung der Zuschauer (sagt dort vor 1034 doch der "Schauspieldirektor", daß dieses Stück die "Guten zu noch Besseren" mache). Darum bezeichnete Lessing die "Gefangenen" nicht nur provozierend als "das vortrefflichste Stück, welches jemals auf das Theater gekommen". Denn Laster müsse man nicht nur beweinen, sondern auch verlachen (Lachmann-Muncker 4,68, vgl. schon 33, später dann S.191), und die "sinnreiche Verspottung der Laster und Ungereimtheiten (ist) die vornehmste Verrichtung der Komödie".
Lessings Wiederentdeckung und Neubewertung des Plautus - Jahrhunderte lang stand er im tiefen Schatten des Terenz - hat jüngst einen sehr belesenen und urteilsfähigen Verteidiger gefunden: G. Chiarini, Lessing e Plauto (Neapel, Liguori), 1983. C(hiarini) wirft darin der Plautus-Philologie unserer Tage vor, ausschließlich in einer "quasi rabbiosa contrazione, una chiusura premeditata" befangen zu sein (S.15), sich immer nur auf das objektiv Beweisbare zurückzuziehen, oder besser: zurückgezogen zu haben; denn in neuester Zeit sei diese Beschränkung "quasi in tutto superata" (163). Die Philologie eines Ritschl, Leo und Fraenkel überholt? Man wird zunächst einige Bedenken verspüren. Doch zunächst sei kritisch referiert, was C. uns über "Lessing e Plauto" berichtet.
Synthetic Water Calibration for Water Quality Parameters & Water Treatment Program Validation

description: To support the Environmental Assessment (EA) of a new gold mine project in BC, McCue completed the preliminary design of a mine water treatment plant (WTP) using a water profile modeled by others for the future open pit sump water. The water profile is complex and the treatment plan includes heavy metals removal by chemical precipitation. Plant effluent quality was initially predicted largely based on published theoretical heavy metal solubility data. To address uncertainty with the treatment process and improve the inputs for the impact assessment model (by others), McCue created a synthetic water sample from field leachate samples and laboratorygrade salts to match the modeled plant inlet water profile. The synthetic water sample was used to validate the water treatment process at a bench scale and provide effluent quality data for impact assessment modeling. The bench scale test program also provided valuable data needed in the future to advance the design of the mine water treatment plant from preliminary to detailed. Data from the bench scale work reduced uncertainty as to what could be achieved with water treatment at the project site and what impact the treated water would have on the local environment. This was important in satisfying both the regulators reviewing the EA and the project stakeholders, including local First Nations. The bench scale test results and data from an ensuing full-scale treatment plant at another project site have also contributed to the body of knowledge for heavy metals precipitation treatment performance. For instance, previously, literature indicated that no or negligible removal could be achieved for copper. McCue’s work has provided valuable data for copper that could benefit EA work at other mine sites globally. McCue will present the synthetic sample method, bench scale test program results, and how they related to the detailed design and performance of a full-scale metals precipitation plant that offered an economical treatment program for complex water containing high levels of salts in addition to heavy metals.
