A Framework for “Driving Under the Influence
of Drugs” Policy for the Opioid Using Driver
Authors: Wilhelmi Brian
Published: March 2021

Background: Driving under the influence of drugs (DUID) is a term used to designate the action of
driving an automobile after the consumption of drugs or medications other than alcohol that interfere
with the capacity to operate a vehicle safely. Unlike recreational drugs, prescription medications pose
a unique challenge to those attempting to harness their benefits yet protect the driving public. As
studies demonstrate a steady increase in opioid use and abuse in the United States, these same
constituencies must regulate a significant percentage of drivers who are under the influence of
opioids.
Objective: This article examines current DUID policy and attempts to present unified suggestions for
improvement based on best scientific evidence of opioid-induced psychomotor impairment.
Study Design: Literature Review
Methods: A literature search was conducted regarding the epidemiology of opioid use and abuse,
psychomotor effects of opioids, DUID, and state policy concerning DUID. A total of 23 epidemiological
studies, 3 studies on acute psychomotor effects, 32 on chronic psychomotor effects, and selected
pertinent law and policy were reviewed.
Results: Current state law concerning DUID is variable and often relies on prosecutorial discretion to
provide protection of the driving public and prosecution of the truly impaired.
Limitations: The design of various studies included in this review imposes limitations on the
epidemiological data extracted. Relationships between opioids and automobile accidents are
commonly reviewed in retrospect. The data on opioid-induced psychomotor impairment and its
effects on driving an automobile require further direct study to examine current inferences.
Conclusions: A sizable percentage of the driving public has detectable levels of opioids within
their bodies. The best available evidence demonstrates psychomotor impairment following acute
administration of opioids or an increase in opioid dosage, but impairment diminishes with chronic,
stable opioid usage. Policy makers must account for this evidence when balancing the benefit of pain
relief against the need for public roadway protection when drafting DUID legislation.
Key words: Driving under the influence of drugs, DUID, psychomotor impairment, opioids,
regulation, automobile accident(s), driver impairment, prescription drugs, chronic opioid analgesic
therapy, driving under the influence
Opioids and Neuropathic Pain
Authors: Smith Howard S.
Published: March 2021

Opioids are broad spectrum analgesics that may be beneficial to alleviate the intense
perception of algesia in patients suffering with pain. They have been one of the most
controversial analgesics, in part because of their potential for addiction. Opioids or any
currently available analgesic will not provide effective analgesia for every patient with
chronic neuropathic pain (NP), but overall opioids are considered to be a second or third
line class of analgesics that may provide reasonable analgesia to some patients with chronic
NP. Although opioids may alleviate chronic NP, overall, NP tends to be less opioid responsive
than nociceptive pain. The mechanisms that may contribute to neuropathic pain may
simultaneously also contribute to diminishing the antinociceptive properties of opioids for
neuropathic pain. Some of these mechanisms may also contribute to analgesic tolerance
and/or opioid-induced hyperalgesia. Hyperalgesia consequently to nerve insult and opioidinduced analgesic tolerance, may both involve the N-methyl-D-aspartate (NMDA) receptor
and share part of intracellular events producing a state of neural hyperexcitation. Conversely,
opioid therapy may contribute to nociceptive processes that may be involved in neuropathic
pain such as opioid-induced cholecystokinin release. Furthermore, within NP, peripheral NP
appears to be the most opioid responsive, followed by spinal NP while supraspinal NP tends
to be the least responsive to opioids. Although, there is no robust evidence that any specific
opioid agent is better than any other opioid at effectively treating NP, it is conceivable that
some opioids/opioid-like analgesic agents may be particularly well suited to alleviate NP in
certain patients suffering from neuropathic pain.

Importance of Axial Migration of Spinal Cord
Stimulation Trial Leads with Position
Authors: Kim Chong H.
Published: March 2021

Background: Spinal cord stimulation (SCS) is an established treatment option for chronic pain.
Prior to permanent implantation, temporary trials are performed to evaluate the SCS treatment.
During the trial period, it is common for the patients to experience changes in paresthesias.
However, it is unclear what the role of lead migration is, if any, in the changes in paresthesia.
Objective: To evaluate the role of lead migration on the effect of postural stimulation changes
during SCS trials.
Study Design: Case series.
Setting: University pain management center.
Methods: X-rays of the patients with successful trials, in sitting and standing position, were
obtained at the end of a 7 day SCS trial. Data were collected based on the need for adjustment
of the stimulation settings due to changes in paresthesias with postural change of sitting versus
standing.
Results: The average lead migration was 3.05 mm inferiorly from a standing to sitting position
for all subjects. The average migration was 2.85 mm in subjects requiring adjustment of the
SCS setting due to change in paresthesia compared to 3.24 mm for those who did not require
adjustment regardless of position. The results were insignificant based on P = 0.17.
Limitations: Small sample size, case series.
Conclusions: This case series demonstrates continued support for the role of the width of the
cerebral spinal fluid space as the significant factor on paresthesia changes in SCS with respect to
postural changes, even during the trial period.
Key words: Spinal cord stimulation, postural change, lead migration, paresthesia,

Published: March 2021

Tujuan penelitian tindakan kelas atau yang dikenal sebagai PTK merupakan salah satu hal mendasar yang dapat dilakukan oleh guru sebagai seorang peneliti. Pelaksanaan sebuah penelitian tindakan kelas umumnya dilatarbelakangi oleh rendahnya nilai hasil belajar siswa. Penelitian tindakan kelas dilaksanakan karena rendahnya hasil belajar siswa pada pembelajaran IPA mengenai materi sistem pencernaan manusia. Keadaan ini disebabkan oleh banyaknya istilah sains dan proses pencernaan yang perlu dipelajari dan dipahami siswa serta upaya guru dalam penyampaian materi masih terlalu monoton dan dirasa membosankan oleh siswa. Oleh karena itu, penerapan metode circuit learning dipilih pada pelaksanaan PTK di kelas lima sekolah dasar agar dapat meningkatkan hasil belajar siswa. Dari hasil pengamatan dan penelitian yang dilakukan, dapat dibuktikan bahwa hasil belajar siswa mengalami peningkatan karena dengan penerapan metode ini, siswa diarahkan juga dikondisikan untuk selalu melakukan pengulangan materi yang telah dibahas sebelumnya. Berdasarkan analisis yang dilakukan, hasil penelitian yaitu seluruh siswa terbukti mampu mencapai nilai di atas standar ketuntasan minimum. Selain itu pula, pemetaan konsep, media visual, serta audio visual dimanfaatkan sebagai pendukung keberhasilan penerapan metode ini. Dengan demikian, pemanfaatan metode circuit learning dapat menjadi salah satu pendekatan alternatif yang dapat digunakan dalam rangka meningkatkan pemahaman serta kemampuan siswa dalam memperoleh hasil belajar yang lebih baik.

Hacia una teoría literaria post-secular: repensando la crítica liberal de la religión a través de Flora Tristán, Paul Gauguin y Vargas Llosa en "El paraíso en la otra esquina"
Authors: Poggi Alfredo Ignacio
Published: March 2021

Este artículo postula que la crítica a la religión es la temática central de la novela El paraíso en la otra esquina, brindando una alternativa al desafío crítico de encontrar un factor unificador de las dos historias de la obra, tanto de Flora Tristán como de Paul Gauguin. Utilizando el concepto post-secular de Jürgen Habermas, las tres hipótesis de la secularización de José Casanova, la crítica a una visión esencialista de la religión de Talal Asad y los tres estadios del desarrollo secular de Charles Taylor, este análisis tiene el objetivo de cuestionar la oposición binaria entre lo secular y lo religioso que permea la obra de Vargas Llosa. A través de una revisión de la narrativa de la secularización, eurocentrista y moderna, presente en la novela, se intenta puntualizar la vaguedad de la definición de lo religioso, la porosidad del cuadro inmanente creado por el autor, y la resistencia del lector a una oposición binaria transhistórica que sugiere potencialidades humanas naturales, las cuales se realizan al liberarse de la religión
Teoría utópica y espacio urbano. El sueño de la ciudad ideal en la narrativa española
Authors: García Noelia S.
Published: March 2021

Categorizar el concepto de utopía resulta muy complejo al tratarse de un género fronterizo. Establecer un modelo o prototipo utópico es prácticamente imposible ya que cada autor ofrece su propia visión sin adscribirse a ningún tipo concreto. Los elementos sobre los que sustenta el modelo utópico son el espacio y el tiempo. Normalmente suele desarrollarse en una ciudad, representada como un no lugar (Marc Augé). En el caso concreto de la narrativa española, el género utópico ha quedado relegado a la periferia del sistema, focalizándose únicamente sobre textos gestados durante el siglo XIX y de naturaleza política, lo que ha llevado incluso a la negación de la existencia de utopías. El fenómeno utópico español tiene unas características especiales que lo hacen diferenciarse de los modelos canónicos. Esta circunstancia hace que se acerque a otras disciplinas a la vez que se aleja del ámbito estrictamente literario, dando lugar a un género fronterizo e híbrido. El presente artículo pretende realizar una revisión histórico-crítica del género utópico español a través de seis títulos que ilustran las peculiaridades del género en España.

Authors: Adkins Monty
Published: March 2021

Roberto Gerhard fue un pionero de la música electrónica en Inglaterra, autor de más de veinte obras significativas, entre las que se encuentran conciertos, obras de teatro y piezas para radio desde 1954. Sin embargo, por diversas razones políticas, culturales y personales, su música electrónica no ha sido, ni publicada, ni apenas divulgada hasta el momento. La música electrónica de Gerhard es uno de los repositorios más ricos para comprender el desarrollo de la técnica compositiva tardía del compositor y el desarrollo temprano de la música electrónica en Reino Unido. El presente escrito presenta el resumen de una década de trabajo dirigida por el autor del artículo y realizada por los investigadores Carlos Duque y Gregorio Karman en el archivo Roberto Gerhard de la Biblioteca de la Universidad de Cambridge (CUL) de Inglaterra. Este archivo alberga libros, manuscritos, cuadernos de notas y, lo más importante para el presente artículo, más de 600 cintas magnéticas del compositor. Aunque algunas de estas cintas contienen grabaciones de obras compuestas por otros autores, la mayoría pertenecen a composiciones instrumentales y electrónicas de Gerhard. El artículo abarca aspectos relacionados con sus métodos compositivos, su estudio o su relación con el Taller Radiofónico de la BBC. El escrito se basa en publicaciones previas del autor del artículo, concretamente In Search of a Third Way y Claustrophilia: A Musical Gift from Gerhard to John Cage. Por otra parte, el artículo proporciona una lista revisada y actualizada de las obras electrónicas del compositor existentes, basada en la investigación realizada en el archivo de cintas.

Published: March 2021

Sulfur refers to the harmful impurities of cast iron, deteriorating the quality of the metal. Therefore, much attention is paid to the problem of reducing sulfur in the iron, and then in steel. Most of the sulfur is dissolved in the iron as FeS. One method of non-domain removal of sulfur from cast iron is desulfurization. As a reagent in this process, powdered calcined lime CaO is used. The article presents the results of thermodynamic modeling of the Ca, Fe // O, S system within the framework of the generalized theory of "regular" ionic solutions. The equations for calculating the activity of the components of the system under study are derived. The energy parameters of the model are calculated taking into account the experimental data and melting characteristics of pure oxides and sulfides for the systems CaO – CaS, FeO – FeS, FeS – CaS, FeO – CaO. The values of the energy parameters are in good agreement with the experimental data. Calculated binary state diagrams of the system under study. The diagrams FeO – FeS, СaO – CaS, FeO – CaO, FeS – CaS are calculated over the entire molar fraction from 0 to 1. The Gibbs energy of the exchange reaction FeS + CaO = FeO + CaS is determined on the basis of the following data: thermodynamic parameters characterizing the processes the melting of oxides and sulfides of iron and calcium, the values of the reduced thermodynamic potential Ф_T^o and standard enthalpies of substances ∆_f H_(0,i)^o at absolute zero. Based on the values of the energy parameters calculated for the doubles and the Gibbs energy of the exchange reaction, a FeS – CaO diagram with a simple eutectic at 90 mol. % FeS and 10 mol. % CaO, melting at 1407 K.

Thin films of lead sulfide obtained by various physicochemical methods are widely used as IR detectors, ion-selective sensors, sensors of temperature and humidity, in solar radiation converters due to a high absorption coefficient in the infrared spectrum of 1-3 μm. Researchers note technological simplicity, the absence of high temperatures and vacuum, as well as the possibility of light doping of lead sulfide films during their production by chemical bath deposition from aqueous media. In the present work, we studied the kinetics of hydrochemical deposition of the solid PbS phase from the ammonium citrate reaction mixture. The introduction of barium chloride BaCl2 into the reactor in the concentration range from 0.5∙10-5 to 5∙10-3 mol/l has led to an increase in the induction deposition period from 5 to 30 minutes. In this work, polycrystalline films of individual lead sulfide were synthesized, as well as PbS layers doped with iodine and additionally barium with salt content in the last mixtures from 0.5∙10-5 to 5∙10-3 mol/l. The film thickness varied from 350 to 210 nm. An elemental EDX analysis of the obtained PbS films was performed. For the main components contained in the layers (Pb and S), insignificant non-stoichiometry in composition was established. The morphology of films of PbS during their doping with iodine and barium undergoes significant changes. Thus, if an individual PbS is formed from particles whose average size is 250 nm, then introduction of ammonium iodide into the solution leads to the appearance of grains with an average size of 150-200 nm, and adding the barium salt results a slight increase in the grain size up to 150-300 nm. The share of nanoparticles in these layers is 1-4%. The histograms of the distribution of particles in the films, both for individual and doped PbS, are monomodal.

We present an analysis of 1524 spectra of Vega spanning 10 yr, in which we search for periodic radial-velocity variations. A signal with a periodicity of 0.676 day and a semi-amplitude of ∼10 m s−1 is consistent with the rotation period measured over much shorter time spans by previous spectroscopic and spectropolarimetric studies, confirming the presence of surface features on this A0 star. The activity signal appears to evolve on long timescales, which may indicate the presence of failed fossil magnetic fields on Vega. TESS data reveal Vega’s photometric rotational modulation for the first time, with a total amplitude of only 10 ppm. A comparison of the spectroscopic and photometric amplitudes suggests that the surface features may be dominated by bright plages rather than dark spots. For the shortest orbital periods, transit and radial-velocity injection recovery tests exclude the presence of transiting planets larger than 2 R
⊕ and most non-transiting giant planets. At long periods, we combine our radial velocities with direct imaging from the literature to produce detection limits for Vegan planets and brown dwarfs out to distances of 15 au. Finally, we detect a candidate radial-velocity signal with a period of 2.43 days and a semi-amplitude of 6 m s−1. If caused by an orbiting companion, its minimum mass would be ∼20 M
⊕; because of Vega’s pole-on orientation, this would correspond to a Jovian planet if the orbit is aligned with the stellar spin. We discuss the prospects for confirmation of this candidate planet.

We have conducted a search for new strong gravitational lensing systems in the Dark Energy Spectroscopic Instrument Legacy Imaging Surveys’ Data Release 8. We use deep residual neural networks, building on previous work presented by Huang et al. These surveys together cover approximately one-third of the sky visible from the Northern Hemisphere, reaching a z-band AB magnitude of ∼22.5. We compile a training sample that consists of known lensing systems as well as non-lenses in the Legacy Surveys and the Dark Energy Survey. After applying our trained neural networks to the survey data, we visually inspect and rank images with probabilities above a threshold. Here we present 1210 new strong lens candidates.
Assessment of trout populations inhabiting the Palena River, southern Chile

A survey of trout species was carried out to assess the trout stocks' quality inhabiting the Palena River Basin, one of the most important rivers for recreational angling in Chilean Patagonia. Six sampling campaigns were carried out over 16 selected stretches of the river between February 2012 and June 2013. A total of 912 trout were collected, 57% rainbow trout (Oncorhynchus mykiss), 33.3% brown trout (Salmo trutta), and 9.6% brook trout (Salvelinus fontinalis). Also, one tiger trout (Salmo trutta × Salvelinus fontinalis) (a hybrid between brown and brook trout) was recorded. Results showed that both rainbow trout and brown trout shared the same reaches of the river, with very similar feeding habits, while brook trout inhabited smaller and more enclosed streams. Maturity stages (V-VI) were recorded from the fish sampled over the period spring-summer-autumn in the case of rainbow trout; autumn-winter for brook trout, and summer-autumn for brook trout. One of the study's most notable features was the small size of the mature brook trout, reaching 17.5 cm in length for gravid females and 12.4 cm for mature males at age 2+. The maximum age recorded for rainbow and brown trout was 6+, with a maximum length of 69.8 and 58.5cm, respectively, while for brook trout, the maximum age recorded was 3+ for a female with a length of 29.9 cm length and 2+ for a male of 16.6 cm.
Faire entendre sa voix : solidarités combattantes et interventions féministes dans le processus de paix colombien
Authors: Boutron Camille
Published: March 2021

Cet article examine la contribution des femmes ex-combattantes des Farc aux négociations de paix ayant abouti à l’accord signé en 2016 entre la guérilla marxiste et le gouvernement colombien. Plus particulièrement, il s’attache à montrer la façon dont la mise en place, à la table des négociations, d’une sous-commission pour le genre a permis aux représentantes de la délégation des Farc de construire une identité stratégique réinvestissant leur expérience de la lutte armée au service de leur engagement féministe. Au travers de la formulation du « féminisme insurgé », les femmes ex-combattantes des Farc ont négocié leur repositionnement sur l’échiquier politique du post-conflit colombien à la fois en tant que femmes, mais aussi en tant qu’ex-combattantes, un précédent dans l’histoire de la participation des femmes aux négociations de paix.
Négocier l’espace humanitaire en Haïti
Authors: Verlin Jan
Published: March 2021

Cet article s’intéresse aux interactions structurées entre organisations humanitaires qui concourrent à construire un espace d’intervention en Haïti entre 2008 et 2016. Son point de départ est de montrer que l’espace social investi par les acteurs humanitaires – légitimé et rythmé par des « situations d’urgence » – oblige les humanitaires à restructurer leurs arènes de négociations, notamment par rapport à leurs participants et leurs objectifs, pour maintenir la légitimité de l’intervention humanitaire. Il montre comment ces adaptations successives entraînent d’une part, une fragmentation des arènes de négociations en une multiplicité d’espaces ad hoc . D’autre part, ces adaptations ne permettent pas vraiment d’évaluer la diffusion ni la force des normes construites dans ces espaces. Enfin, le système de « coordination » des humanitaires perpétue finalement l’existence d’une structure parallèle à l’État local.

Gliomas are common malignant tumors of the central nervous system. Despite the surgical resection and postoperative radiotherapy and chemotherapy, the prognosis of glioma remains poor. Therefore, it is important to reveal the molecular mechanisms that promotes glioma progression. Microarray datasets were obtained from the Gene Expression Omnibus (GEO) database. The GEO2R tool was used to identify 428 differentially expressed genes (DEGs) and a core module from three microarray datasets. Heat maps were drawn based on DEGs. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed using the DAVID database. The core module was significantly involved in several KEGG pathways, such as "cell cycle", "viral carcinogenesis",
"progesterone-mediated oocyte maturation", "p53 signaling pathway". The protein-protein interaction (PPI) networks and modules were built using the STRING database and the MCODE plugin, respectively, which were visualized using Cytoscape software. Identification of hub genes in the core module using the CytoHubba plugin. The top modular genes AURKA, CDC20, CDK1, CENPF, and TOP2A were associated with glioma development and prognosis. In the Human Protein Atlas (HPA) database, CDC20, CENPF and TOP2A have significant protein expression. Univariate and multivariate cox regression analysis showed that only CENPF had independent influencing factors in the CGGA database. GSEA analysis found that CENPF was significantly enriched in the cell cycle, P53 signaling pathway, MAPK signaling pathway, DNA replication, spliceosome, ubiquitin-mediated proteolysis, focal adhesion, pathway in cancer, glioma, which was highly consistent with previous studies. Our study revealed a core module that was highly correlated with glioma development. The key gene CENPF and signaling pathways were identified through a series of bioinformatics analysis. CENPF was identified as a candidate biomarker molecule.
