Pushing the boundaries: Marginal phonemes and dialogic interaction
Authors: Evans Nicholas
Published: December 2022

Phonemes with restricted distribution represent an interesting analytic challenge. Well-known sources include the adoption of certain phonemes from other languages in borrowed words, emerging phonemic splits, and special phonological subsystems (e.g. ideophones). This paper aims to widen our conception of such marginal phonemes, by incorporating another source: specific vocal gestures called into play in interactional settings. Our initial puzzle involves a restricted phoneme set in the Papuan language Nen: two classes of sounds are restricted to interactive contexts, namely interjections and deictics. These sounds are the nasal vowels ã , ẽ , and the glottal fricative h . Several questions arise here. Should these restricted sounds be considered part of the phoneme system? How did they evolve? How does their presence interact with seemingly equivalent sounds in neighbouring languages, in contexts of possible loanwords? We then pass to two other languages where sounds that are unquestionably phonemes have, in at least some phonotactic positions, clear correlations with interactive uses: initial /ð/ in English, essentially restricted to words of person (thou), space (that), time (then), or discourse deixis (the, though), and glottal stops with morphemic function in Bininj Kunwok, restricted to immediate aspect[43], addressee-engaged demonstratives, and kinship vocatives. It is already known that non-phonemic speech sounds (e.g. what is written mhm in English) are used in interaction. This paper proposes that the special phonetics of interaction can integrate further into the sound system and, in such cases as those presented here, either expand the phonological system in absolute terms by adding new phonemes, or expand the phonotactic possibilities of phonemes already occurring in other phonotactic positions.

“Meaning ⇔ Text” Theory and the linguistic universe of Igor Mel’čuk
Authors: Ivanova Svetlana Viktorovna , Larina Tatiana Viktorovna
Published: December 2022

The introductory article to the special issue dedicated to Igor Mel’čuk summarizes the main tenets of his “Meaning ⇔ Text” theory, and outlines its contribution to the development of diverse areas of modern linguistics. This theory can be characterized as a formalized, semantically oriented, multilevel, structural, functional and global model of language which explains the way the speaker generates the meaning embodied in the text. Both the article and the volume as a whole show the relevance of this theory for the development of semantics, grammar, pragmatics, typology and lexicography and highlight its theoretical and practical implications for linguistic studies and interdisciplinary research. We then briefly present the articles in this issue. Some of them were written directly in line with the “Meaning ⇔ Text theory” and were influenced by Mel’čuk’s ideas; others were the result of the stimulus that this theory, like its author, gave to the comprehension of the complex issues arising from the description of various levels of the language system. But all of them are related to Igor Mel’čuk, both as a linguist and a personality, and they are dedicated to him.

Metformin is the most often prescribed first-line oral antidiabetic. This review summarized the effects of Metformin on the body, its role in diabetes prevention and treatment, and the adverse effects of metformin administration. A PubMed search for metformin-related papers in diabetic patients was performed. We included articles on any metformin oral dosage in people with or without type 2 diabetes that reported favorable and unfavorable outcomes. Relevant studies from the references provided were reviewed. Metformin controls the blood glucose level by multiple mechanisms. These include increasing the cell sensitivity to insulin and reducing endogenous glucose secretion by the liver. Also, Metformin has been shown to assist in weight reduction in obese patients. Some early investigations showed that lifestyle changes and Metformin significantly reduced the incidence of diabetes in high-risk people, and lifestyle interventions were more effective than Metformin. Some trials indicated Metformin was not associated with any significant endangerment or advantage in terms of cardiovascular incidents. However, Metformin tended to be more effective in longer trials involving younger individuals regarding cardiovascular outcomes. The microvascular complication prevalence was insignificant between Metformin and other treatment interventions including placebo and lifestyle interventions. The gastrointestinal symptoms are common with metformin use as compared to placebo. Metformin increased the risk of lactic acidosis, especially in moderate and severe renal impairment settings, thus considered contraindicated. However, due to the low reported incidence of lactic acidosis associated with Metformin and the potential protective properties on the kidney, heart, and liver, it is advised to carefully balance the risk and benefits of Metformin when treating diabetes. In addition, Metformin has been shown to cause consequences other than gastrointestinal symptoms, such as vitamin B12 deficiency which can lead to hematologic issues, such as anaemia and peripheral neuropathy. Thus, periodic measurement of vitamin B12 for individuals treated with Metformin is recommended.
Prevention, Treatment and Eradication of NTDs by Concerted Efforts-Prognosis and Prediction
Authors: Bajaj Mohini , Nanda Sanju
Published: December 2022

Abstract: Neglected Tropical Diseases (NTDs) are diseases of poverty most prevalent in continents Africa, some parts of Asia, and the low-income regions of G20 countries. The name was given because of the neglect of the global burden of this category of diseases leading to lesser and lesser control strategies by one and all. Although medically diverse, neglected diseases share features that allow them to persist in extreme poverty. The mortality rates with these diseases are relatedly low, but morbidity rates, the main concern, are comparatively higher. This review covers the importance of the control of the NTDs at different levels of control community, national and international levels missed by many of the publications. The visual impact of most diseases is manifested in the form of disfigurement, blindness, and disabilities believed to be dreadful stigmas that people try to hide. Keeping in mind this aspect, there is an urgent need to convince most people to contribute to controlling and preventing the further spread of these diseases. Thus, motivating community-level control. The first detailed study on the global burden of these diseases and the risk factors involved was initiated by the World Bank in 1992. A follow-up study was performed in 2005. This was the basis for the start of the fight against these diseases, initially selecting the eight most affecting diseases and then gradually increasing to 13 by 2006. World Health Organization also released its first report on NTDs in 2010, compiling all the related aspects. The report was the basis for selecting diseases as targets and reached 17 diseases by 2013. Most of the reviews have not highlighted the importance of the various pharmacoeconomics and pharmacoepidemiology strategies which can be incorporated to get better results in eradicating these diseases. The main bottleneck is the inaccurate and imprecise measurement of the disease burden from the data, which does not give a clear picture of the disease. The detail of parameters selected for most of the measurement of disease burden, Disability- Adjusted Life Year (DALY), and measuring tools, which have been incorporated from time to time to meet the requirement, are also covered. The review also highlights the role played by different strata of a system for better control of these diseases.

AS PRINCIPAIS TÉCNICAS UTILIZADAS PARA REMOÇÃO DE CORANTES DAS ÁGUAS RESIDUAIS DA INDÚSTRIA TÊXTIL: UMA REVISÃO
Authors: Oliveira Chaves Nayane , Freitas de Carvalho Luana Caliandra , Pessoa Betânio Oliveira Rosane Maria
Published: December 2022

A indústria têxtil gera uma grande quantidade de águas residuais durante seus processos produtivos. Entre os compostos químicos encontrados nesses efluentes, estão os corantes que possuem difícil degradação e são tóxicos para o meio ambiente. Este estudo apresenta uma visão geral sobre as principais técnicas utilizadas para tratamento das águas residuais da indústria têxtil, analisando o funcionamento e a eficiência de cada técnica. Atualmente, as técnicas mais aplicadas são adsorção, coagulação e floculação, filtração por membrana, processos biológicos e processos oxidativos avançados. A adsorção é um método muito aplicado para remoção de corantes, sendo utilizado geralmente o carvão ativado como adsorvente. A coagulação e floculação envolve a adição de produtos químicos para coagular os sólidos coloidais e facilitar sua remoção por sedimentação floculenta. A filtração por membrana inclui as técnicas de microfiltração, ultrafiltração, nanofiltração e osmose reversa. O tratamento biológico pode ser realizado por processos aeróbios, anaeróbios ou uma combinação de ambos. Por fim, os processos oxidativos avançados utilizam fortes agentes oxidantes para a degradação de poluentes e compreendem os métodos de ozonização, fotocatálise, processos Fenton e Foto-Fenton. Uma vez que cada técnica possui vantagens e desvantagens, deve ser realizada uma avaliação criteriosa para a escolha da técnica apropriadavlevando em conta os custos e os benefícios. Ademais, observa-se que a utilização de processos combinados poderá suprir as deficiências apresentadas pelos processos quando são utilizados individualmente.
INIBIDOR DE CORROSÃO DE ORIGEM VEGETAL: REVISÃO EM ARTIGOS PUBLICADOS NO BRASIL
Authors: Nascimento Dantas Maria Clara , Pressentin Cardoso Sheila
Published: December 2022

A pesquisa teve o objetivo de avaliar artigos publicados em revistas brasileiras com o tema inibidores de corrosão de origem vegetal. A corrosão é um processo espontâneo nos metais, intensificado pelo meio corrosivo onde se encontram e as condições nas quais irão operar, trazendo prejuízos para vários setores industriais e a sociedade. Dentre os métodos de proteção da corrosão destacam-se os inibidores, que além de eficientes na proteção dos metais podem ser adicionados ou retirados de processos industrial conforme a necessidade de uso. Contudo, o caráter tóxico de substâncias presentes em inibidores comerciais levou a busca por produtos ambientalmente seguros, de modo que extratos de vegetais passaram a ser testados como potencial materia ativa na formulação de inibidores de corrosão. De caráter exploratório e bibliográfico, a avaliação dos artigos envolveu quatro categorias de análise: aspectos gerais; natureza dos materiais; técnicas experimentais, conclusões e eficiência dos extratos. Dos quatorze artigos identificados seis abordaram o uso de vegetais nativos do Brasil, várias partes dos vegetais foram testadas, com destaque para as folhas, havendo um uso diversificado de técnicas de extração. O aço carbono foi o metal mais usado, assim como o meio ácido, com os ensaios de corrosão envolvendo técnicas clássicas. Ficou evidente a relação direta entre a eficiência de determinado extrato às condições experimentais usadas, como natureza do extrato, o tipo de aço, o meio corrosivo e a temperatura de teste, de modo que essas informações precisavam ser claramente apresentadas. Em dez artigos o extrato do vegetal apresentou eficiência de inibição da corrosão entorno de 90%, valores que indicaram o potencial desses vegetais como método de proteção, sendo pesquisas iniciais que necessitam de outros estudos para que tenham uso comercial. Dentro do universo pesquisado, os trabalhos sobre o tema desenvolvidos no país acompanharam o que vem sendo realizado internacionalmente.

Authors: Da  Rocha P. A. M. B , Freitas-Junior A.S.Q. , A. Melo Andréa , R. da Luz Elaine
Published: December 2022

Durante a pandemia de COVID-19, o presente projeto foi proposto a dois alunos do Curso Técnico em Química do campus Nilópolis do IFRJ, que abraçaram a ideia de realizar experimentos em casa, usando a câmera de um smartphone, soluções de corantes alimentícios e aplicativos de medição de cores. Embora não tenha sido possível uma comparação estatística com os resultados obtidos com um espectrofotômetro, os experimentos foram direcionados para a verificação da influência das condições experimentais sobre os resultados da análise e para a simulação da validação de um método analítico. Estudos preliminares com corantes azul, verde e vermelho e com os aplicativos ColorMeter, Color Grab e PhotoMetrix PRO levaram a escolha por fazer a determinação dos parâmetros analíticos de mérito para o corante vermelho, usando o canal G (do sistema de cores RGB) do aplicativo PhotoMetrix PRO, com fundo branco e uma iluminação secundária. Curvas analíticas na faixa de 0,80 a 4,0 cc mL-1 (micro colher de chá por mililitro) foram obtidas com R2 entre 0,9714 e 0,9891 com comportamento homocedástico confirmado pelo teste de Cochran. Os limites de detecção e quantificação foram determinados pelo teste da percepção visual, sendo 0,32 e 1,1 cc mL-1, respectivamente. Para os níveis de concentração de 1,2 e 2,4 cc mL-1, a precisão intermediária entre dias foi de 8,9 e 8,3%, respectivamente. Já os valores de recuperação variaram entre 99 e 120% para o nível de fortificação de 1,2 cc mL-1 e entre 102 e 104% para o nível de fortificação de 2,4 cc mL-1. A metodologia alternativa para a simulação do desenvolvimento e da validação de um método analítico em casa, de acordo com os critérios estabelecidos pelo INMETRO, foi considerada adequada e promissora. Além disso, o experimento relatado pode ser prontamente adaptado para vários objetivos de aprendizagem de química analítica.
COVID-19 Death: A Bibliometric Analysis and Review
Authors: Halim Mohammad
Published: December 2022

Reviewing published articles on COVID-19 and death is the goal of the
study. In this review, we conducted a thorough analysis of the
literature from 2019 to 2022. To search the literature, we chose the Web
of Science database. Every step of the process is documented on excel
sheets for more transparency and clarity, and all research is subjected
to stringent inclusion and exclusion criteria before being considered.
For this bibliometric analysis, a total of 4,746 papers were chosen, and
all irrelevant publications were disregarded. PRISMA 2020 is applied to
the process of inclusion and exclusion. The findings showed that
COVID-19 and mortality variables such as pneumonia, obesity, and
influenzas are frequently discussed in the literature. According to the
review, the United States has published the most articles of any country
that its authors are from. However, several Chinese universities and
authors have had the most influence on the Covid-19 and death research.
There is room for more study that focuses on regional differences in
COVID-19 and mortality.
The Role of Groundwater Flow in a Montane, Semi-Arid, Headwater Catchment
Authors: Salberg Lauren , Anderson Suzanne , Ge Shemin
Published: December 2022

Groundwater is critical in sustaining streamflow, especially in
headwater catchments, because of its ability to supply baseflow. In
water-limited arid and semi-arid mountain environments, the need to
characterize groundwater recharge and discharge has grown in tandem with
demands to manage current and future water resources. However, studying
groundwater in complex terrain is challenging due to limited field
measurements. Nearly a decade of monitoring in Gordon Gulch in the
Colorado Front Range provides an opportunity to study such an
environment. The field data is used to parameterize and calibrate a
groundwater flow model (MODFLOW-NWT). Model results reveal that
groundwater is recharged primarily during one to two recharge periods
each year, driven by spring snowmelt coupled with rain or by
intense/prolonged summer rain. Gordon Gulch is a net gaining stream,
with greater fluxes from groundwater to stream in lower Gordon Gulch and
during springtime. Groundwater is discharged to the stream via long,
deep flowpaths sourced from upper Gordon Gulch and from hillslopes, and
via short, shallow flowpaths in lower Gordon Gulch. Modelled groundwater
accounts for approximately 16 to 34% of baseflow in the stream. Using
Gordon Gulch as a case study, this model and data analysis contribute to
a larger effort to understand and constrain the mechanisms driving
groundwater recharge and groundwater-stream exchanges in semi-arid,
headwater catchments.

Cardiac arrhythmias are a leading cause of mortality, morbidity, and
sudden cardiac death (SCD). Current treatment strategies for ventricular
tachycardia (VT) are effective for many patients; however, in several
cases, this does not result in a cure. Despite significant clinical
improvements, conventional catheter ablation remains relatively
unsuccessful in achieving the best outcomes in some challenging cases.
Stereotactic arrhythmia radioablation (STAR), which delivers precise
high-dose radiation to well-defined targets with minimal damage to
surrounding tissue, is emerging as a new potential treatment option,
having the potential to be used for patients at high risk for catheter
ablation or who have refractory VT. Ongoing studies and preliminary
experiences on f the efficacy of STAR in patients with refractory VT
have shown a reduction in VT recurrence and a promising early safety
profile. However, STAR is in its infancy, and clinical evidence on its
efficacy and safety is limited; thus, conclusions regarding the efficacy
of STAR should be drawn with caution. Further investigation of long-term
efficacy and tolerability is ongoing to substantiate this promising
therapeutic option better. The present review describes the background
and general principles, pretreatment procedures, clinical implications,
and toxicity of STAR therapy.
Deriving and testing parameter values for a parsimonious soil erosion model

Published: December 2022

Every application of soil erosion models brings the need of proper
parametrization, i.e., finding physically or conceptually plausible
parameter values that allow a model to reproduce measured values. No
universal approach for model parametrization, calibration and validation
exists, as it depends on the model, spatial and temporal resolution and
the nature of the datasets used. We explored some existing options for
parametrization, calibration and validation for erosion modelling
exemplary with a specific dataset and modelling approach. A modified
version of the Morgan-Morgan-Finney (MMF) model was selected,
representing a balanced position between physically-based and empirical
modelling approaches. The resulting calculator for soil erosion (CASE)
model works in a spatially distributed way on the timescale of
individual rainfall events. A dataset of 142 high-intensity rainfall
experiments in Central Europe (AT, HU, IT, CZ), covering various slopes,
soil types and experimental designs was used for calibration and
validation with a modified Monte-Carlo approach. Subsequently, model
parameter values were compared to parameter values obtained by
alternative methods (measurements, pedotransfer functions, literature
data). The model reproduced runoff and soil loss of the dataset in the
validation setting with R of
0.89 and 0.76, respectively. Satisfactory agreement for the water phase
was found, with calibrated saturated hydraulic conductivity (k
) values falling within the interquartile range of k
predicted with 14 different PTFs, or being within
one order of magnitude. The chosen approach also well reflected specific
experimental setups contained in the dataset dealing with the effects of
consecutive rainfall and different soil water conditions. For the
sediment phase of the tested model agreement between calibrated
cohesion, literature values and field measurements were only partially
in line. For future applications of similar model applications or
datasets, the obtained parameter combinations as well as the explored
methods for deriving them may provide guidance.
Brugada Syndrome and Anesthesia: A Systematic Review
Authors: Suchal Zafar Aleem , Afzal Ahmad , Karim Amin H.
Published: December 2022

Brugada Syndrome is an inherited disorder causing specific changes on
electrocardiogram (ECG) pattern of right bundle branch block and
persistent ST elevation in right precordial leads increases the risk of
cardiac arrest and fatal arrhythmia. Patients with brugada are prone to
abnormal cardiac rhythms which can be induced by alcohol, stress, vagal
stimulation, and certain medications. Thus medications are divided into
different classes from I to III with I carrying the most evidence for
potential arrhythmia while III being the least likely. Exceptional care
needs to be taken to avoid anesthetic and analgesic during surgeries for
such patients as several of the known anesthesia medications can lead to
arrhythmia in these patients. In this review we aimed to study the
effect different anesthetic and analgesic medication could have on
patients with brugada syndrome. We conducted a systematic review
following PRISMA guidelines to query PubMed, Embase, Cochrane library
and ProQuest electronic databases. Mesh combinations and synonyms of
“Brugada Syndrome”, “Anesthesia”, “Analgesics” were used. We
included all original human studies that focused on outcomes of
anesthetic and analgesics on patients with brugada. After screening 1149
studies, we included 49 articles consisting of a total of 1414 subjects
for qualitative analysis. We found local analgesics to be least likely
to lead to potential arrhythmic complications with other systemic and
inhaled agents having a risk although the risk varied because of
multitude of reasons ranging from type of drug to patient factors like
the patient’s condition and type of Brugada. We concluded that
anesthetic although could be used for individuals with Brugada the type
of anesthetic to be used should be selected keeping the potential
cardiac risk under consideration.
ANALYSIS OF ELECTROSEISMIC CONVERSION IN AN UNBOUNDED ROUGH SURFACE
Authors: ZHANG SEN
Published: December 2022

Electroseismics is a procedure that uses the conversion of
electromagnetic to seismic waves in a fluid-saturated porous rock due to
the electrokinetic phenomenon. This paper concerns the time-domain
analysis of such an electroseismic conversion problem in an unbounded
structure in three dimensions. Using an exact transparent boundary
condition and suitable interface conditions, we study an initial-
boundary value problem for the coupling of Maxwell’s equations and the
Biot’s equations. The well-posedness and stability are established for
the reduced problem. Our proof is based on the method of energy, the
Lax-Milgram theorem, and the inversion theorem of the Laplace transform.
Moreover, a priori estimates with explicit dependence on the time are
achieved for the quantities of electric filed and solid-fluid fields by
taking special test functions for the time-domain variational problem.

Afrinophilina orapa: a new genus and species of Paederinae (Coleoptera: Staphylinidae) from Cretaceous lacustrine deposits at Orapa Diamond Mine, Botswana.
Authors: Mnguni Sandiso , McKay Ian , Badenhorst Shaw
Published: December 2022

A new genus and species of a staphylinid beetle, Afrinophilina
orapa gen. et sp. n., is described using a single well-preserved
compression fossil from an Upper Cretaceous fossil insect deposit, the
Orapa Diamond Mine in Botswana. Afrinophilina is placed in the
extant subfamily Paederinae based on concealed antennal insertions, and
hypomeron with a well-developed post-coxal process. It is placed among
the Pinophilini based on an elongated procoxae (as long as the
profemora), broad, oval, fully exposed trochantin, and a conspicuous
second abdominal segment. The new species is placed in the Pinophilina,
rather than the Procirrina, based on the presence of well-preserved pair
of paratergites on segments III-VIII. Characters which may distinguish
this new species from other Pinophilina include the lack of an
emarginate shape of the rear margins of the elytra, broad neck, and
having two pairs of paratergites on each side of segments III-VI. This
is the earliest occurrence of a member of the Pinophilina. It is the
first member of the Pinophilina from the Southern Hemisphere,
particularly the African continent. Similarly, compared to other fossil
staphylinids, the fossil also portrays morphological stasis dating back
to the Cretaceous, thereby suggesting a punctuated equilibrium pattern
of evolution.
Design Strategies of the Mantis Shrimp Spike: How the Crustacean Cuticle Became a Remarkable Biological Harpoon?
Authors: Delaunois Yann , Tits Alexandra , Grossman Quentin , Smeets Sarah , Malherbe Cedric , Eppe Gauthier , Lenthe Harry van , Ruffoni Davide , Compere Philippe
Published: December 2022

Spearing mantis shrimps are aggressive crustaceans using specialized
appendages with sharp spikes to capture fishes with a fast movement.
Each spike is a biological tool that have to combine high toughness, as
required by the initial impact with the victim, with high stiffness and
strength, to ensure sufficient penetration while avoid breaking. We
performed a multimodal analysis to uncover the design strategies of this
harpoon based on chitin. We found that the spike is a slightly hooked
hollow beam with the outer surface decorated by serrations and grooves
to enhance cutting and interlocking. The cuticle of the spike resembles
a multilayer composite: an outer heavily mineralized, stiff and hard
region (with average indentation modulus and hardness of 68 and 3 GPa),
providing high resistance to contact stresses, is combined with a less
mineralized region, which occupies a large fraction of the cuticle (up
to 50%) and features parallel fibers oriented longitudinally, enhancing
stiffness and strength. A central finding of our work is the presence of
a tiny interphase (less than 10 μm in width) based on helical fibers and
showing a spatial modulation in mechanical properties, which has the
critical task to integrate the stiff but brittle outer layer with the
more compliant highly anisotropic parallel fiber region. We highlighted
the remarkable ability of this helicoidal region to stop
nanoindentation-induced cracks. Using three-dimensional multimaterial
printing to prototype spike-inspired composites, we showed how the
observed construction principles can not only hamper damage propagation
between highly dissimilar layers (resulting in composites with the
helical interphase absorbing 50% more energy than without it) but can
also enhance resistance to puncture (25% increase in the force required
to penetrate the composites with a blunt tool). Such findings may
provide guidelines to design lightweight harpoons relying on
environmentally friendly and recyclable building blocks.

This study aims to formulate an evaluation method for digital learning materials that is relevant to the development model used. A qualitative approach with an evaluative design through in-depth analysis is applied to student research reports, specifically research on the development of digital learning materials. The formative evaluation method chosen and the reasons for the selection were analyzed and the results were discussed in a focus group discussion. The sample was taken from the results of research by prospective teacher. Expert review was conducted to test the validity of the content and test the design. Content validity test can be done qualitatively or quantitatively by applying Lawshe, Aiken, or Gregory techniques. The design test was carried out with a black-box test. White-box testing is very rarely implemented and is recommended when developing using a programming language. One-to-one and small group tests were conducted using think aloud, cognitive walk through, or heuristics techniques. The results of the analysis found that the formative evaluation methods of teaching materials needed were expert review, one-to-one, small group, and field evaluation. Furthermore, for field tests, inquiry methods can be applied with various techniques, such as learning object review instrument (LORI), user experience questionnaire (UEQ), or system usability scale (SUS).
