The Provision of Mathematics and Statistics Support in Scottish Higher Education Institutions (2017) – A Comparative Study by the Scottish Mathematics Support Network
Authors: Ahmed Shazia , Davidson Peter , Durkacz Kate , Macdonald Calum , Richard Morgiane , Walker Alan 
Published: May 2018

The Scottish Mathematics Support Network (SMSN) was formed in July 2008 with the aim of creating a support network for people working in Scottish universities who were involved with, or wished to be involved with, providing mathematical and/or statistical support for their students. The consensus of the SMSN is that increasingly more students need assistance with their basic mathematical and statistical skills than was the case in the past, and that consequently mathematics support is an area on which universities will need to focus on in future years. Through networking and professional development opportunities with other practitioners in the field of mathematics and statistics support, the SMSN have developed and maintained strong links with individual practitioners, and more broadly with like-minded groups such as the sigma Network and the Irish Mathematics Learning Support Network. With the provision of mathematics and statistics support becoming more prevalent in UK Higher Education institutions, it seemed timely to assess the current state of this provision in Scotland, and to compare with the rest of the British Isles. At the 2016 SMSN AGM, it was unanimously agreed that such a study should be carried out with the SMSN committee taking responsibility for conducting the research.
Review a legacy resource: a new feature in MSOR Connections to aid discovery of hidden gems
Authors: Rowlett Peter 
Published: May 2018

Over recent decades, our community has operated numerous projects and produced countless resources. Certainly some of these were of their time and are now of limited value, but many still offer huge potential for those engaged with teaching, learning, assessment and support in higher education mathematics, statistics and OR. However, projects that are no longer running may not be in a position to advertise their resources, so how will people discover them? I write to propose a new feature in MSOR Connections that would offer short reviews of legacy resources. These could be resources for use with students or teaching practice guides. The aim is to shine a light on little-used, perhaps-forgotten but good-quality resources produced under now-defunct projects.
Different Flow Behaviors of Low-Pressure and High-Pressure Carbon Dioxide in Shales
Authors: Jia Bao , Tsau Jyun-Syung , Barati Reza 
Published: May 2018

Summary
Understanding carbon dioxide (CO2) storage capacity and flow behavior in shale reservoirs is important for the performance of both CO2-related improved oil recovery (IOR) and enhanced gas recovery (EGR) and of carbon sequestration. However, the literature lacks sufficient experimental data and a deep understanding of CO2 permeability and storage capacity in shale reservoirs under a wide range of pressure. In this study, we aimed to fill this gap by investigating and comparing CO2-transport mechanisms in shale reservoirs under low- and high-pressure conditions. Nearly 40 pressure-pulse-transmission tests were performed with CO2, helium (He), and nitrogen (N2) for comparison. Tests were conducted under constant effective stress with multistage increased pore pressures (0 to 2,000 psi) and constant temperature. The gas-adsorption capacity for CO2 and N2 was measured in terms of both Gibbs and absolute adsorption. Afterward, the gas apparent permeability was calculated incorporating various flow mechanisms before the adsorption-free permeability was estimated to evaluate the adsorption contribution to the gas-transport efficiency. The results indicate that He permeability is the highest among the three types of gas, and the characteristic of CO2 petrophysical properties differs from the other two types of gas in shale reservoirs. CO2 apparent porosity and apparent permeability both decline sharply across the phase-change region. The adsorbed phase significantly increases the apparent porosity, which is directly measured from the pulse-decay experiment; it contributes positively to the low-pressure CO2 permeability but negatively to the high-pressure CO2 permeability.

Abstract
The study's objectives were to assess the extent to which packaged water producers follow product registration procedures and to assess the relationship between product registration and drinking water quality in Accra, Ghana. Following preliminary analysis of a national water quality survey, 118 packaged sachet water samples were collected by sampling all brands sold by 66 vendors. A sample of vendors was selected from two high-income and two low-income areas of Accra, Ghana. Sachet packaging and labelling details were recorded and compared to a regulatory database to assess product registration. All samples were weighed and tested for faecal indicator bacteria and selected physico-chemical parameters. Product registration numbers and brand names could be matched to regulatory records for 77 of 118 sachets (65.2%). All samples tested were compliant with national water quality standards for faecal indicator bacteria and nitrate. Brand registration was not associated with any of the quality indicators considered. The results of this study suggest that while a substantial proportion of sachet water is sold without formal product registration, the microbial quality of the unlicensed water is consistently high in Accra, Ghana. Further examination of regulatory enforcement and monitoring will be needed to ensure sustained high water quality over time.
O matrimônio sagrado yin-yang:
Authors: Gonçalves Grazieli Aparecida , Lopes Adriana Goreti de Oliveira 
Published: May 2018

Pretende-se por meio deste artigo demonstrar a importância da integração dos opostos proposta pela filosofia chinesa e o processo de individuação presente na psicologia analítica, tendo em vista que esta ideia tem influência direta na concepção dos arquétipos de anima e animusdescrita por Carl G. Jung. Utilizando um estudo bibliográfico com ênfase na metodologia qualitativa, buscou-se analisar as consequências, para as mulheres, da dissociação do princípio feminino (yin) e o princípio masculino (yang), partindo do pressuposto que o processo de individuação representa o tornar si mesmo. A essência humana contém em si ambas polaridades, de modo a existir uma complementação dos princípios que deve ser trabalhada internamente para que ocorra o matrimônio sagrado. Quando não há integração dos opostos, a individuação não ocorre, podendo resultar em uma anima negativa (que tenderá a reprimir as suas ações, sentimentos e a sexualidade); assim como ao rejeitar a sabedoria da sua intuição, bem como um animus negativo tornará a mulher uma moralizadora, cheia de dogmas e inflexível às opiniões alheias, com tendências agressivas e prisioneira das suas próprias crenças e julgamentos. Portanto, revela-se fundamental para a saúde mental e qualidade das relações interpessoais das mulheres a necessidade de resgate do sagrado arquétipo feminino e o acolhimento e integração das virtudes masculinas.
"ALORS" EST-IL UN MARQUEUR DE THÉMATISATION DISCURSIVE?
Authors: PĂUNESCU Marina-Oltea 
Published: May 2018

Could alors be a marker of discursive thematization? The article considers a particular case in the usage of “alors”, aiming to show that this lexeme has, in colloquial French, an original function. It cannot be transferred to any other type of formal marker – and a specific one –, while also activating the inherent anaphoric dimension of its semantics. Thus, “alors” has the particularity of linking the discursive sequence it precedes to a previous question. The anaphorization works, therefore, at the dialogical level (Q alors R), and not at the propositional level (q alors p). This confirms the problematological essence of the discourse while also emphasizing its (implicit or explicit) structural questions.
REZUMAT. Să fie oare alors o marcă de tematizare discursivă? Articolul ia în calcul un caz particular de utilizare al lui « alors », cu intenţia de a arăta că acest lexem are, în franceza colocvială, o funcţionare originală. Aceasta nu poate fi transferată asupra niciunui alt tip de marcă formală – şi specifică – în măsura în care activează dimensiunea anaforică inerentă semantismului său. Astfel, « alors » are particularitatea de a pune în legătură secvenţa discursivă pe care o prefaţează cu o întrebare prealabilă. Anaforizarea funcţionează prin urmare la nivel dialogic (Q alors/deci R), şi nu propoziţional (q alors/deci p), confirmând esenţa problematologică a discursului şi atrăgând atenţia asupra întrebărilor (implicite sau explicite) care-l structurează.
Cuvinte cheie: alors, problemă (întrebare), problematică, D-temă.
Ares y Dionisos: Discurso político y poesía trágica en Fenicias de Eurípides
Authors: López Saiz Brenda 
Published: May 2018

En este trabajo, proponemos que en Fenicias de Eurípides se realiza una reflexión meta-dramática a partir de la oposición entre dos campos semánticos: por una parte, la guerra y la discordia, el poder político, el interés individual y el discurso público asociado a prácticas “sofísticas”; por otra, la paz y la concordia entre los miembros de la comunidad, los vínculos de philía, el bien colectivo y la mousiké coral, objeto a su vez de pasajes auto-referenciales. A través de ella, nos parece que la obra se plantea críticamente ante la situación política y bélica que Atenas enfrenta alrededor de 411-409 a.C –periodo en que se sitúa con mayor probabilidad su representación– y, a la vez, realiza una reflexión acerca de la función social de la poesía trágica, oponiéndola a las nuevas formas discursivas que, codificadas y enseñadas por los “sofistas”, se imponen en el ámbito público ateniense.
Este trabajo se inscribe en el proyecto Fondecyt de Iniciación N°11140911, dedicado al estudio de la producción tardía de Eurípides.

Published: May 2018

Abstract
OBJECTIVE To characterize spatial release of platinum from carboplatin-impregnated calcium sulfate hemihydrate (CI-CSH) beads by use of an agarose tissue phantom.
SAMPLE 3-mm-diameter beads (n = 60) containing 4.6 mg of carboplatin (2.4 mg of platinum)/bead.
PROCEDURES 18 L of 1% agarose was prepared and poured into 36 containers (10 × 10 × 10 cm), each of which was filled half full (0.5 L/container). After the agarose solidified, 1, 3, 6, or 10 CI-CSH beads were placed on the agar in defined patterns. An additional 36 blocks of agar (0.5 L/block) were placed atop the beads, positioning the beads in the center of 1 L of agar. The experiment was replicated 3 times for each bead pattern for 24, 48, and 72 hours. At these times, representative agarose blocks were sectioned in the x-, y-, and z-planes and labeled in accordance with their positions in shells radiating 1, 2, 3, 4, and 5 cm from the center of the blocks. Agarose from each shell was homogenized, and a sample was submitted for platinum analysis by use of inductively coupled plasma–mass spectroscopy.
RESULTS Platinum diffused from CI-CSH beads at predicted anticancer cytotoxic concentrations for 2 to 5 cm.
CONCLUSIONS AND CLINICAL RELEVANCE Results provided information regarding the spatial distribution of platinum expected to occur in vivo. Agarose may be used as a diffusion model, mimicking the characteristics of subcutaneous tissues. Measured platinum concentrations might be used to guide patterns for implantation of CI-CSH beads in animals with susceptible neoplasms.

Abstract
OBJECTIVE To determine effects of 3 plasma concentrations of fentanyl on the minimum alveolar concentration of isoflurane (MACiso) and cardiovascular variables in Hispaniolan Amazon parrots (Amazona ventralis).
ANIMALS 6 adult parrots.
PROCEDURES In phase 1, anesthesia was induced and maintained with isoflurane; intermittent positive-pressure ventilation was provided. The MACiso was determined for each bird by use of a bracketing method and supramaximal electrical stimulus. Fentanyl (20 μg/kg) was administered IV, and blood samples were collected over time to measure plasma fentanyl concentrations for pharmacokinetic calculations. In phase 2, pharmacokinetic values for individual birds were used for administration of fentanyl to achieve target plasma concentrations of 8, 16, and 32 ng/mL. At each concentration, MACiso and cardiovascular variables were determined. Data were analyzed with mixed-effects multilevel linear regression analysis.
RESULTS Mean ± SD fentanyl plasma concentrations were 0 ng/mL, 5.01 ± 1.53 ng/mL, 12.12 ± 3.58 ng/mL, and 24.93 ± 4.13 ng/mL, and MACiso values were 2.09 ± 0.17%, 1.45 ± 0.32%, 1.34 ± 0.31%, and 0.95 ± 0.14% for fentanyl target concentrations of 0, 8, 16, and 32 ng/mL, respectively. Fentanyl significantly decreased MACiso in a dose-dependent manner. Heart rate and blood pressure significantly decreased at all fentanyl doses, compared with values for MACiso at 0 ng of fentanyl/mL.
CONCLUSIONS AND CLINICAL RELEVANCE Fentanyl significantly decreased the MACiso in healthy Hispaniolan Amazon parrots, but this was accompanied by a depressive effect on heart rate and blood pressure that would need to be considered for application of this technique in clinical settings.

Abstract
OBJECTIVE To compare the disposition of fentanyl citrate after a single IV injection in isoflurane-anesthetized red-tailed hawks (Buteo jamaicensis) and Hispaniolan Amazon parrots (Amazona ventralis).
ANIMALS 6 adult red-tailed hawks and 6 adult Hispaniolan Amazon parrots.
PROCEDURES Anesthesia was induced and maintained with isoflurane; intermittent positive-pressure ventilation was provided. The minimum alveolar concentration of isoflurane was determined for each bird by use of the bracketing method and a supramaximal electrical stimulus. Fentanyl (20 μg/kg) was administered IV. Arterial (red-tailed hawks) or jugular venous (Hispaniolan Amazon parrots) blood samples were obtained immediately before and 1, 2, 4, 8, 15, 30, 60, 120, 180, 240, and 480 minutes (red-tailed hawks) and 1, 5, 10, 15, 30, 60, 120, and 180 minutes (Hispaniolan Amazon parrots) after fentanyl administration.
RESULTS A 3-compartment and a 2-compartment model best described fentanyl pharmacokinetics in red-tailed hawks and Hispaniolan Amazon parrots, respectively. Median apparent volume of the central compartment and volume of distribution at steady state were 222 mL/kg and 987 mL/kg, respectively, for the red-tailed hawks and 5,108 mL/kg and 13,079 mL/kg, respectively, for the Hispaniolan Amazon parrots. Median clearance and elimination half-life were 8.9 mL/min/kg and 90.22 minutes, respectively, for the red-tailed hawks and 198.8 mL/min/kg and 51.18 minutes, respectively, for the Hispaniolan Amazon parrots.
CONCLUSIONS AND CLINICAL RELEVANCE Pharmacokinetic results for fentanyl in isoflurane-anesthetized red-tailed hawks and Hispaniolan Amazon parrots indicated large differences and should strongly discourage extrapolation of doses between these 2 species.
