What is the ideal grade of resection for parasagittal meningiomas with the invasion of superior sagittal sinus? Simpson I or Simpson II resection? A retrospective observational study
Authors: Aguiar Paulo Henrique Pires , Dos Santos Rafael Rodrigues Pinheiro , Marson Fernando Augusto Lima , Dezena Roberto Alexandre , Rampazzo Ana Carla Mondek Rampazzo
Published: September 2022

Background:

Parasagittal meningioma (PSM) is a tumor located in the parasagittal angle which extends to and/ or invades the superior sagittal sinus (SSS). Surgical resection of the PSM, the standard treatment in such cases, poses a challenge for neurosurgery, particularly where there is an invasion of the SSS. This is due to the risk of complications through injury to the adjacent vascular structures. The objective of the study was to perform a comparative evaluation of the surgical techniques for total resection of the PSM (Simpson Grade [SG] I and SG II), which present the highest rates of success in terms of the following variables: mortality, recurrence, and postoperative complications.

Methods:

Fifty-six patients undergoing resection surgery for PSM with the invasion of the SSS were enrolled. The patients were divided into two groups: Group A, comprising 26 cases of patients subjected to SG I PSM resection surgery and Group B, with 31 cases of patients subjected to SG II PSM resection surgery, with preservation of the SSS.

Results:

The results showed that Group B had lower rates of postoperative deficit (P = 0.026), zero mortality, and reduced recurrence. The use of complementary radiotherapy for atypical meningiomas (WHO II) in Group B was satisfactory in controlling the disease.

Conclusion:

The Simpson II, with preservation of the SSS, was better as it diminishes the vascular risks of surgery, reduces the frequency of severe postoperative deficit, and reduces mortality.

Here, we advance an omics approach to understand how lithium salts in locally super-concentrated electrolytes (LSCEs) should be mixed to create stable ionically conductive interphases in high-power Li|NMC811 cells charged to high voltage. Mixed-anion LCSEs maintain an areal ion flux of 6 mA cm–2 during discharge across 500 cycles with 70% capacity retention, outperforming single-salt LSCEs as well as single- and dual-salt concentrated electrolytes. These advantages stem from the enrichment of cathode–electrolyte interphases with fluoroethers, which suppress cathode corrosion and fracturing.

Populismo y televisión en el Perú: De los medios de las masas a las masas de los medios
Authors: Protzel Javier
Published: September 2022

Los casi cincuentaicuatro años que separan la arenga de Haya de la Torre en la Plaza de Acho del mitin con que Alan García cierra su campaña en el Paseo de la República -prolongado por sucesivos "balconazos" presidenciales- ilustrarían con facilidad cómo ciertos rasgos de las culturas subalternas perduran a pesar de las obvias e importantes diferencias de caracterización que a lo largo de ese extenso periodo encontramos en la sociedad peruana. No obstante, ese olor de multitudes es indisociable del modo en que las masas construyen lo real a través de los medios de comunicación; el campo de mirada de las ciencias políticas debe extenderse al estudio de la cultura de masas para asir lo permanente y lo cambiante en una dimensión más amplia. En este ensayo se esboza una reflexión teórica sobre el tema.
SYMBOL AS THE OBJECT OF PHILOSOPHICAL REFLECTION
Authors: Климов Сергей Николаевич , Сачкова Елена Владимировна
Published: September 2022

Статья посвящена анализу эволюции понятия «символ» как одной из основополагающих категорий философии. В современном мире символ и символические системы подвергаются глубокой трансформации, меняется не только их смысловое наполнение, но и роль в жизни социума, что требует переосмысления данного понятия. Генезис символа рассматривается в диахронической ретроспективе с целью определения различных подходов к данному понятию и выявлению общего и особенного в понимании символа. Проанализированы философские учения о символе от античной философии до философии нашего времени. Зародившиеся в античной философии подходы к пониманию символа предопределили основные вектора движения философской мысли в его осмыслении: с одной стороны, онтологическое понимание данного феномена как атрибута божественной сущности, а с другой - гносеологический подход к символу как инструменту познания вызвал его десакрализацию и профанацию, в то же время расширив его понимание как эстетической категории, наделенной аксиологической и прагматической функциями. Коллизии XX в. привели к тому, что традиционные символические системы либо претерпели глубинные изменения, либо были разрушены, что способствовало деградации символа, его трансформации в симулякр.

The given article is devoted to the evolution of the concept of «symbol» as one of the fundamental categories of philosophy. In the modern world symbol and symbolic systems are undergoing crucial transformations. Their semantics as well as their role in the life of the human society are transforming. All these makes the philosophical rethinking of this concept quite necessary. The genesis of symbol is viewed diachronically which helps to identify different approaches to the notion of symbol and to indicate the general and the particular in it. The analysis of philosophical studies from ancient philosophy up to modern time is given the article. Ancient Greece philosophical studies defined the main trends of philosophical thought concerning the essence of symbol. The phenomenon of symbols was ontologically understood as the attribute of the divine essence. The epistemological approach to the symbol as an instrument of cognition led to its desecration. But at the same time, it expanded its understanding as an aesthetic category with axiological and pragmatic functions. The collisions of the XX century led to profound changes in the traditional symbolic systems or to their destruction thus contributing to the deterioration of symbol and its mutation into a simulacrum.

THEOLOGICAL DISCOURSE AND DENOMINATIONAL DIFFERENTIATION IN PROTESTANTISM
Authors: Лебедев Владимир Юрьевич
Published: September 2022

Статья посвящена структурной семиотике протестантского теологического дискурса. Сложность этой на первый взгляд часто дискутируемой проблемы начинается с семантической неопределенности самих слов, неизбежно используемых для номинации: например, фундаментализм используется в широком регистре, от неопределенного именования с уничижительными коннотациями до самообозначения групп и направлений. Также и именования протестантских объединений отличается асимметричностью: почти одинаковые наименования для существенно разных общин и наоборот. Следующая проблематичность определяется применением современного системно-структурного подхода в области анализа религиозных явлений. Конфессиональные и деноминационные объединения включают теологию с определенными дискурсивными свойствами в качестве субсистемы в системных границах. При попытке представить варианты теологического дискурса в рамках традиционного конфессионального подразделения добиться полного, симметричного соответствия не получается. Поля описания, используемые для разных компонентов религиозного сообщества (теология, богослужение и т. п.) несимметричны, так как сама система не функционирует в привычном для классического религиоведения «двоично-зеркальном» пространстве. В результате возникает необходимость характеризовать спектр вариантов теологии для каждого выделенного подразделения, порой с уточнением типичности того или иного типа теологического дискурса для выбранной конфессиональной единицы.

The paper sets out to explore the structural semiotics of Protestant discourse. Although the topic is familiar for the research agenda, the words habitually used for nomination in discourse are semantically vague. Such word as fundamentalism has a wide register of meanings from general nomination tinged with pejorative connotations to regular self-naming chosen by groups and trends. Moreover, Protestant affiliations of almost opposite views are often named identically, rendering nomination in Protestant discourse asymmetric. Modern systemic and structural approach gives rise to other complications when used for analysis of religious phenomena. Denominational affiliations integrate theology with its discourse characteristics as a subsystem within a given systemic framework. But it proves impossible to present varieties of theological discourse within the frameworks of traditional denominational divisions as symmetrically consistent. The descriptive fields defining different components of religious community (such as theology, services, and the like) are far from symmetric as the system itself does not operate in binary-symmetric domain traditional for classical religious studies. As a result, for each denomination an entire range of variants of theology should be described as typical for a chosen denomination.
K.D. KAVELIN ABOUT UNIVERSITIES: IN SEARCH OF SCIENTIFIC AND EDUCATIONAL IDENTITY
Authors: Михайлова Елена Евгеньевна
Published: September 2022

Заграничные поездки русского историка и общественного деятеля второй половины XIX века К.Д. Кавелина рассмотрены как проявление академической мобильности и, одновременно, как поиск научной и образовательной идентичности. Изучая деятельность французских, немецких, швейцарских университетов, Кавелин стремился собрать материал, способный обогатить традиции российских университетов. Сделан вывод о том, что полученные сведения русского ученого-посланника оказались важными в нескольких перспективах. Во-первых, взгляд со стороны позволил обнаружить новые научные и образовательные формы университетской деятельности. Во-вторых, близкое знакомство с зарубежными коллегами помогло обрести чувство принадлежности к научному и профессорскому сообществу. В-третьих, взгляд изнутри способствовал критической переоценке ранее заимствованных представлений.

Foreign trips of the Russian historian and public figure of the second half of the 19th century K.D. Kavelin are considered as a manifestation of academic mobility and, at the same time, as a search for scientific and educational identity. Studying the activities of French, German, Swiss universities, Kavelin sought to collect material that could enrich the traditions of Russian universities. It is concluded that the information received by the Russian scientist-envoy was important in several perspectives. Firstly, the view «from outside» made it possible to discover new scientific and educational forms of university activity. Secondly, close acquaintance with foreign colleagues helped to gain a sense of belonging to the scientific and professorial community. Thirdly, the view «from the inside» contributed to a critical reassessment of previously borrowed ideas.

Inversion Formulas for the Three-Dimensional Volterra Integral Equation of the First Kind with Prehistory
Authors:   Irkutsk State University, Antipina Ekaterina ,   Melentiev Energy Systems Institute SB RAS
Published: September 2022

The article is devoted to solving one class of Volterra equations of the first kind with variable upper and lower limits. These equations were introduced in connection with the problem of identifying asymmetric kernels for constructing integral models of nonlinear dynamical systems of ”input-output” type in the form of Volterra polynomials. To solve the identification problem, previously introduced test signals with duration h (grid sampling step) are used in the form of a linear combination of Heaviside functions. The article demonstrates a method for obtaining the desired solution, which develops the step method for the one-dimensional case. Matching conditions are established that ensure the desired smoothness of the solution.

We consider nonlinear Kantorovich problems with marginal distributions and cost functions depending measurably on a parameter and prove that there exist optimal transportation plans that are also measurable with respect to the parameter. Unlike the classical linear Kantorovich problem of minimization of the integrals of a given cost function with respect to transportation plans, we deal with nonlinear cost functionals in which integrands depend on transportation plans. Dependence of cost functions on conditional measures of transportation plans is also allowed.
Simulating Electrification of Aircraft in a Domestic New Zealand Environment
Authors:   , Shellard Cameron
Published: September 2022

Global attention has been drawn towards aviation emissions due to the lack of a low carbon substitute, this is exacerbated in New Zealand as there are no alternatives to aviation for rapid transit between cities. An alternative energy storage to aviation fuel being developed is electrical energy, typically in the form of batteries. Simulating and modelling are integral to the development of novel technologies like electric aircraft. However, due to the lack of data, software models are difficult to validate. This thesis details the design and testing of a Hardware-in-the-Loop Simulation, which utilises software to represent airframes and aerodynamics and hardware to represent an electrified powertrain of a Bombardier Q300. The developed system will be used to investigate flight paths for custom airframes and novel powertrains.

Effectiveness of Ambulation on Self-Care Abilities among PatientsExtubated from the Ventilator
Authors: Bromeo Ashwin , Clement I
Published: September 2022

Background: Intensive care unit (ICU) is a major component of health care environment in a hospital where ventilation support plays a crucial role, and this makes the patients to be restricted to bed and may face difficulties in their self care abilities after extubation. The present study aimed to assess the effectiveness of ambulation on the level of self-care abilities of patients weaned from the ventilator in the intensive care unit. Objective: The objectives of the study were to assess the level of self-care abilities, to determine the effectiveness of ambulation, and the association with clinical variables among patients weaned from the ventilator in the interventional and non-interventional groups. Methodology: A quasi-experimental time-series design was adopted for this study. The study was conducted with a sample size of 30. The interventional group patients (n=15) received ambulation after weaning and the control group patients (n=15) received routine ICU care. The distance and period of ambulation were progressively increased for the next five days from the initial visit. Data were collected about their activities of daily living for up to five days. Results: In the pretest, all the 15 (100%) patients were in a dependent state. On the fifth day of observation, 14 (93.3%) patients were independent and only one (6.7%) was partially dependent in the interventional group. Out of 15 patients in the non-interventional group, only nine (60%) were partially dependent, and six (40%) were independent on the fifth day of observation. There was a statistical significant improvement (p <0.001) in the level of self-care abilities within the interventional group, between the pretest and post-test values taken on the second, third, fourth, and fifth day of observation. Practicing ambulation after weaning from the ventilator was found to be effective. There was a significant improvement in the level of self-care abilities between the interventional and non-interventional groups on the second, third and fourth day of observation (p <0.05). Conclusion: The findings of the present study suggests that all intensive care nurses can practice ambulation for the patients soon after they are weaned from the ventilator to regain their self-care abilities as early as possible.
Evaluating the effects of observation period, floral density, and weather conditions on the consistency and accuracy of timed pollinator counts
Authors: Mahon Neil , Hodge Simon
Published: September 2022

Insect pollinators are experiencing substantial declines as a result of habitat loss, agricultural intensification, invasive pests, and climate change. To investigate factors causing pollinator declines, evaluate the success of conservation measures, and institute long-term monitoring schemes, it is essential to validate and standardize pollinator sampling techniques. This study investigated how sampling duration, weather conditions, and abundance of floral resources influenced the results of timed pollinator counts by repeatedly sampling the same pollinator assemblage in an Irish meadow.  The likelihood of detection of Apis mellifera, Bombus spp, solitary bees, and Syrphidae was strongly associated with the density of floral units or floral cover in the observation plot.  Also, even though protocol criteria restricted pollinator counts to the middle of the day and benevolent weather, pollinator counts were strongly influenced by factors such as cloud cover, light levels, wind speed and relative humidity. Increasing the duration of the timed counts from 5-minutes to 30-minutes considerably increased the probability of detection of each pollinator group.  Additionally, the perceived diversity of the pollinator assemblage at the meadow was markedly affected by sampling duration and floral abundance.  To improve the consistency or comparability of studies using timed pollinator counts, we recommend that criteria are set restricting surveys to narrow ranges of weather conditions and floral density when possible.  Additionally, pollinator field investigations or monitoring programs would benefit from a systematic evaluation of how erroneous non-detection of target taxa can be reduced to acceptable levels by modifying sampling duration.
“I just smoke marijuana, which is not a drug, and cigarettes, which is a drug”: Health Perceptions of Cannabis Use Among African American Tobacco Smokers
Authors: Cottrell-Daniels Cherell , Shorey Fennell Bethany
Published: September 2022

Cannabis and tobacco co-use has increased in recent years, including co-administration, in which tobacco and cannabis are consumed simultaneously. One common method of co-administration is the use of blunts, in which cigars or little cigars and cigarillos (LCCs) are combined with cannabis. LCC use is associated with negative health outcomes and is elevated among Black/African American populations and lower income adults. Little is known about health perceptions of LCCs among these populations, particularly as it relates to cannabis use. We report results from a mixed-methods study examining multiple tobacco use among African American adults. Participants (N=22) were largely single (81.8%), male (59.1%), and had an annual household income of less than $30,000 (72.7%). All participants used combustible cigarettes in the past month (M days=26.23, SD=7.38) and the majority (91.0%) used LCCs in the past month (M days=14.24, SD= 0.67). Of these, 50.0% reported using LCCs with cannabis all or some of the time. Participants who reported co-use smoked LCCs marginally more days (M=18.45, SD=11.88) than those who used LCCs alone (M=9.60, SD=7.12, t(19)=-2.04, p = .055, d=.89). Perceptions of the health risks of LCCs compared to combustible cigarettes were variable among those who reported co-use and those who did not. For example, 45.5% of co-users vs. 20.0% LCC only users said they “Don’t know” if LCCs are more or less harmful than cigarettes, whereas 27.3% of co-users and 10.0% LCC only users thought LCCs were “More harmful.” There was no difference between the groups on overall relative risk perceptions (χ2(3)=4.25, p=.24). Semi-structured interviews assessed tobacco use motives, including cannabis consumption, risk perceptions, and stress. Similar to quantitative indices, participants reported variable perceptions of the health risks associated with co-use of cannabis and tobacco. For example, a number of participants indicated that smoking LCCs with cannabis may be healthier than smoking them with the original tobacco inside. Many reported different motives for seeking out cannabis vs. nicotine (e.g., coping with stress, social situations). Quotations from qualitative interviews will be included on the poster. In conclusion, health risk perceptions among this sample demonstrate the need for clearer public health messaging regarding tobacco products and co-use with cannabis.
The impact of cannabis edible packaging elements on appeal, harm perceptions and knowledge: an experimental study among a national convenience sample of adults in the United States
Authors: Reboussin Beth , Wagoner Kimberly , Sutfin Erin , Cornacchione Ross Jennifer , Suerken Cynthia , Romero-Sandoval Edgar Alfonso , Lazard Allison
Published: September 2022

The state-legalized cannabis industry is rapidly evolving, and regulators lack scientific data as to how product packaging should be regulated to protect public health. Cannabis edibles in particular pose unique public health and regulatory challenges. While smoking cannabis results in an immediate high, intoxication from consuming edibles can be delayed up to 2 hours or more which can lead to overconsumption of THC, particularly by naïve users. The packaging of edibles as appealing food products may also reduce harm perceptions. The goal of this pilot study was to examine the impact of flavor imagery and a cannabis warning on product appeal, harm perceptions, knowledge, and willingness to try edibles. We recruited a convenience sample of 700 adults ages 19-79 (mean age 38), 52% female, 77% white, 14% Hispanic, 59% college-educated from Amazon Mechanical Turk (MTurk). Participants were randomized to one of four experimental conditions to view a cannabis edible package that varied by presence of fruit imagery (yes/no) and type of warning (Washington State cannabis warning; control warning). More than half of our sample had tried edibles and 36% were current users. Participants viewing packages with fruit imagery were significantly more likely (p<0.05) than participants viewing packages without fruit imagery to think the product was appealing (69% vs 39%) and safe to consume (69% vs 52%) and were more likely to want to try the product (58% vs 39%). Among participants exposed to the cannabis warning, only 42% believed the package clearly indicated how to safely consume it and fewer than half knew the correct serving size, which was not significantly different than those not viewing the warning. Only 17% of those viewing the warning knew the effects could be delayed by more than two hours. These results provide preliminary evidence of the impact of product packaging on appeal, knowledge, harm perceptions and willingness to try cannabis edibles and demonstrate the need for improved, edible-specific warnings to educate consumers about safe use.
Medical Marijuana & Me (M3): Designing Measures of Medical Marijuana Dose in an Observational Study
Authors: Fechtel Hannah , Sajdeya Ruba , Wang Yan , Spandau Gabriel , Goodin Amie , Winterstein Almut , Cook Robert
Published: September 2022

Measuring marijuana exposure represents one of the biggest challenges in marijuana-related outcomes research. The challenge mainly emerges from the significant variability in medical marijuana (MMJ) use characteristics on both the product level, including inter-product and intra-product composition variability and possibility of using multiple consumption modes, and the patient level, including variations in use patterns, frequency and intensity of use, and routes of administration. While MMJ-related observational research still mainly relies on self-reported MMJ exposure, there remains a lack of validated and reliable exposure measures and a lack of standardized dose units, necessitating the development of such measures. In the Medical Marijuana & Me (M3) study, a new combined cohort and cross-sectional study aiming to assess a multitude of MMJ-related outcomes among MMJ patients in Florida, we developed a set of new comprehensive measures to quantify MMJ use by assessing the specific modes of consumption, doses, frequency, and patterns of MMJ use. After reviewing the literature for existing MMJ measures, a multidisciplinary team of MMJ certifying physicians, pharmacists, researchers, MMJ patients, and dispensary personnel designed and developed a questionnaire covering a wide range of MMJ products, including flower, vape cartridges, concentrates for smoking, topical products, tinctures, oral concentrates, edible products, and others. MMJ dose and use are assessed via a nine-item MMJ use measure for each MMJ product participants use that gauges modes and routes of administration, frequency of use (per day, per week, per month), amount of consumed products, tetrahydrocannabinol and cannabidiol concentrations and ratios, and potency. For specific consumption modes (e.g., smoking and vaping), additional questions (e.g., number of inhalation seconds) were included to ensure a comprehensive approach of exposure measurement. Visual prompts such as product example photos were also included to enhance participant engagement and ease. We pilot-tested the questionnaires on twenty current MMJ patients in Florida, who provided feedback to improve the measures’ relatability and enhance accuracy in capturing their MMJ exposure. Some of the key challenges we encountered were measuring the “amount” of solid and liquid concentrates, and difficulty in determining dose of vape cartridges due to inconsistencies in THC concentration between nearly identical cartridges. The nine-item MMJ use questionnaire developed for M3 offers a framework for MMJ exposure quantification in current and future observational MMJ-outcomes research. Analyses resulting from M3 data will add to the sparse literature on MMJ dose measures and assist in validating measures similar to the measure developed for M3.
Effect of Acute Stress Induction on Cannabis Demand
Authors: Chang Yi-Chun , Ladd Benjamin
Published: September 2022

Objective: Substance demand, defined as the persistently high valuation of a reinforcer, is a critical factor that contributes to initiating and maintaining substance use. This study examined how cannabis demand was affected by an acute stress induction. Here we focused on the most commonly used demand indices: Intensity (i.e., the amount of drug consumed at zero cost) and Omax(maximum expenditure). Method: 33 young adults (66.67% female, 54.55% white, mean age = 22.88 years) reporting cannabis use at least 5 days per week in the past month and at least weekly use in the past 6 months were recruited from the community and a northwest college campus. After confirming eligibility, each participant was scheduled for an online Zoom appointment with an experimenter. During this appointment, participants completed a pre-test stress assessment and Marijuana Purchase Task (MPT). Following, they completed the Trier Mental Challenge Test (TMCT) for stress induction, during which they were asked to work four trials of arithmetic problems while being observed by the experimenter. Finally, they completed the post-test stress assessment and MPT, as well as a cannabis use survey. Results: Stress (d = .58, p = .002) and Intensity (d = .46, p = .014) significantly increased as a result of the stress induction. However, there was no significant difference between the pre-test and post-test in terms of Omax (d = .21, p = .25). Conclusion: This study demonstrates the effectiveness of administering stress induction (i.e., TMCT) online among cannabis users. The study results also suggest heightened cannabis demand in young adult high-frequency cannabis users after experiencing acute stress, suggesting interventions on how to manage stress in the moment may provide valuable techniques for individuals trying to moderate or cut down on their cannabis use.
Do Cannabis PDMPs Change Physician Prescribing Behavior?
Authors: Steuart Shelby
Published: September 2022

As legal medical cannabis has become widespread in the United States, cannabis-related emergency department visits have increased. One reason for this increase is that physicians cannot prescribe medical cannabis, leading to a situation where physicians must rely on their patients to tell them whether they use medical cannabis. Patients may withhold their use of cannabis from their physician out of fear of judgment or fear of changes to their prescriptions. At the same time, almost 400 medications have moderate or severe contraindications for use with cannabis, any of which could cause a poisoning severe enough to warrant hospitalization. To combat this problem of information asymmetry in patient cannabis use, about one-third of states with medical cannabis programs have added cannabis to their state Prescription Drug Monitoring Program (PDMP) over the past few years. This could lead to changes in the physician prescribing behavior, which may result in fewer accidental cannabis-related poisonings. I will explore this question through the application of robust difference-in-difference models to private and public insurance claims data as well as data from Electronic Medical Records.

In surface water body sources intended for domestic system, iron and manganese concentrations has often been presented an increase in its values, it is recurrent during the warm seasons. As the chemical dynamic of water bodies is dependent on the environmental conditions, climatic aspects which affects temperature and dissolved oxygen in the water, will also affect the concentration and structure of these ions. Therefore, the present study aims to evaluate the influence of temperature and rainfall rates on the iron and manganese concentrations of the water source of the Water Treatment System – Terras Baixas, by using statistical methods, in a series of five years of data (2013 to 2017). The results of iron and manganese concentrations shows an increase during the hot seasons, and, through the statistical methods used, it was possible to conclude that, regarding temperature and rain factors, only temperature had a significant influence on these variables.   Keywords: WTS Terras Baixas, Water quality, statistical analysis, correlation, significance Análise da Influência de Fatores Climáticos na Concentração de Ferro e Manganês em Água Bruta Destinada a um Sistema de Tratamento de Água R E S U M ONos mananciais superficiais destinados ao sistema doméstico, as concentrações de ferro e manganês têm apresentado, muitas vezes, um aumento em seus valores, sendo recorrente durante as estações quentes. Como a dinâmica química dos corpos d'água é dependente das condições ambientais, aspectos climáticos que afetam a temperatura e o oxigênio dissolvido na água, também afetarão a concentração e a estrutura desses íons. Portanto, o presente estudo tem como objetivo avaliar a influência da temperatura e dos índices pluviométricos nas concentrações de ferro e manganês do manancial do Sistema de Tratamento de Água – Terras Baixas, por meio de métodos estatísticos, em uma série de cinco anos de dados (2013 a 2017). Os resultados das concentrações de ferro e manganês mostram um aumento durante as estações quentes, e, através dos métodos estatísticos utilizados, foi possível concluir que, em relação aos fatores temperatura e chuva, apenas a temperatura teve influência significativa nessas variáveis.Palavras-chave: ETA Terras Baixas, qualidade da água, análise estatística, correlação, significância

O presente trabalho faz um estudo sobre os Índices de Anomalia de Chuva (IAC) e suas relações com os desastres naturais na cidade de Marabá no sudeste do Pará, Amazônia Oriental. Foram usados dados de precipitação pluviométrica média mensal dos anos de 1973 a 2017 da cidade de Marabá, oriundos do Instituto Brasileiro de Meteorologia (INMET), dados de informações básicas a respeito da Gestão de Riscos e Desastres Naturais da região de Marabá. Estes dados foram obtidos por meio do Instituto Brasileiro de Geografia e Estatística (IBGE), e dados simulados de precipitação do modelo climático Coupled Climate Mode 3. Utilizou-se estatística básica e também a metodologia do próprio IAC, que é uma metodologia eficaz, direta e simples. Desta forma, foi possível obter os índices de anomalias negativas (secas) e positivas (cheias). O resultado dos índices foi divido em três categorias ou intensidades: Fraco (FRA), Moderado (MOD) e Forte (FOR). Para a climatologia da região, março indicou ser o mês mais chuvoso, e o mês mais seco ficou com agosto. O maior volume de chuva ficou com o mês de março e em abril os volumes de chuva começaram a diminuir, atingindo menor valor em agosto, e em setembro os volumes precipitantes começaram a aumentar. Os trimestres mais chuvosos são dezembro, janeiro e fevereiro (DJF) e março, abril e maio (MAM). O trimestre mais seco ficou com junho, julho e agosto (JJA), e em setembro, outubro e novembro (SON) os volumes de chuva começam a aumentar. As ocorrências de EL Niño e La Niña tiveram total relação com os resultados encontrados pelo IAC. Pois em todos os anos de ocorrência de EL Niño ou La Niña, se observou a presença da categoria FOR. Os resultados mostraram que os eventos mais relevantes para as anomalias negativas, encontram-se na categoria FRA e MOD, sendo que estas duas categorias ficaram praticamente equivalentes. E estes resultados, não tiveram relação com as informações da gestão de risco e desastre do local estudado. Para as anomalias positivas, os resultados mostraram que os eventos mais relevantes, encontram-se na categoria MOD, indicando que a região de Marabá é caracterizada por um ambiente chuvoso, e esta caracterização teve total relação com os eventos da gestão de risco e desastre ocorridos em Marabá. Vale ressaltar que o cenário futuro encontrado por meio das simulações, comprovou ser uma intensificação dos atuais padrões de tempo e clima da cidade de Marabá. E de acordo com os noticiários deste ano de 2020, Marabá já está sofrendo com enchentes. Desta forma, o IAC é uma ótima ferramenta para caracterização climatológica e alerta de possíveis áreas de risco.

Inundações e enchentes, decorrentes de inputs pluviométricos e ocupação desordenada das áreas de interflúvio de bacias hidrográficas, aliadas ao déficit estrutural urbano culminam em danos socias, políticos, econômicos e ambientais. As bacias do rio Una e Mundaú são ocupadas por áreas urbanas e agricultura, que degradam o solo e alteram as características naturais da dinâmica hídrica, desse modo o entendimento e caracterização fisiográfica de bacias com uso do solo propício ao desenvolvimento de problemática hídricas é de suma relevância para o gerenciamento e prevenção da propagação de enchentes e inundações. A construção de modelos hidrológicos que possibilitem a compreensão de como água flui através de uma área e como as mudanças nessa área podem afetar o fluxo, ou seja, padrões de escoamento, infiltração e fluxo de água nas bacias, são de suma importância nesse contexto. Utilizando modelagem hidrológica semiautomática com os dados do sensor LiDAR, imageado pelo projeto PE3D no ano de 2016, foi construído um modelo a fim de extrair informações hídricas utilizando a ferramenta Hydrology. Tendo objetivo de demonstrando a necessidade de modelagem hídrica atualiza, que disponibilize dados fidedignos para planejamento adequado e orientação das tomadas de decisão pelos comitês de bacia e poder público. Physiographic characterization of the Una and Mundaú river basins using data from LIDAR, Pernambuco 3DA B S T R A C TFloods and floods, arising from rainwater and/or occupation of the interfluvial areas of the basins, together with the urban structural deficit, culminate in social, political, economic and environmental damage. The Una and Mundaú river basins are occupied by urban areas and agriculture, which degrade the soil and change the natural characteristics of the water dynamics, thus the understanding and physiographic characterization of basins with land use conducive to the development of water problems is essential relevance to the management and prevention of the spread of floods and floods. The construction of hydrological models that enable the understanding of how water flows through an area and how changes in that area can affect the flow, ie, patterns of runoff, infiltration and water flow in the basins, are of paramount importance in this context. Using semi-automatic hydrological modeling with data from the Lidar sensor, imaged by the PE3D project, a model was built in order to extract water information using the Hydrology tool. Aiming at demonstrating the need for updated water modeling, which provides reliable data for proper planning and guidance in decision-making by basin committees and public authorities.Keywords: floods; hydrological modeling; water resources.

Let G = (p, q) be a connected graph and Me(G) be its corresponding edge semi-middle graph. A dominating set D ⊆ V [Me(G)] is split dominating set V [Me(G)] – D is disconnected. The minimum size of D is called the split domination number of Me(G) and is denoted by γs[Me(G)]. In this paper we obtain several results on split domination number.
