Authors: Patil Abhijit S. , Panhalkar Sachin S.
Published: December 2023

The present attempt is made to assess soil erosion and its relationship to landslide incidents in the Panchganga river basin using geospatial techniques. The RUSLE model is used for assessing soil erosion and the FR model is employed for correlation analysis. The static and dynamic components of RUSLE are obtained using multi-source information and an integrated analysis is conducted in the ArcGIS software environment. Landslides are detected using remote sensing datasets and the change detection approach. According to the results of the soil erosion model, 81 % of the study area has a very low risk of erosion while about 21 % has a high and very high risk. The average rate of soil loss in the basin is 83 t/ha/yr. In the correlation analysis, the ratio represents the region where landslides took place to a specific area of an erosion-prone zone. As per the findings, the correlation between soil erosion and landslide incidences indicates that areas with high and very high erosion zones have a higher probability of landslides. The ROC is used to assess the correlation between the soil erosion model and landslide occurrence. According to the assessment results, the AUC indicates an 0.89 correlation between the resulting soil erosion model and landslides.

Authors: Babji Prasad Ch. , Geethamma T. , Prabhakar T.
Published: December 2023

Over the past ten years, there have been more disasters and these catastrophes have a greater impact on communication networks' ability to function. An immediate emergency response is necessary in disaster scenarios. There is a lot of interest in wireless-based emergency response systems since wired emergency response systems have struggled to effectively operate in such time-sensitive circumstances. Several wireless systems and technologies, each having unique properties, advantages, disadvantages are suggested in this respect for application in diverse emergency response scenarios. This study focuses on how recent developments in wireless protocols and communication technologies, particularly mobile technologies and devices, might assist disaster management. In order to encourage the usage of technology using wireless for responding to emergencies, comparison of various wireless advances is presented. This study gives a general overview of how new telecommunications and technology advancements like Massive MIMO, Millimeter wave, Device to device, Non-Orthogonal multiple Access (NOMA) and Cognitive radio might enhance the potential of disaster management networks. It provides broad principles that will aid public safety organisations in selecting wireless technologies that are appropriate for each of them. In contrast to previous surveys, this one focuses on current research objectives and recent advancements in the field of disaster management by emphasising the usage of widely available mobile applications and devices.

Authors: Hunston Christopher , Lee Wei-Tse , Van Muyden Antoine , Bobbink Felix
Published: December 2023

In this work, we looked at the most recent advances in the field of plastics hydrocracking from a technology standpoint. A patent search was supplemented by a literature review to evaluate the development of the hydrocracking technology for plastics recycling. We observed that the patent and academic literature output rapidly increased over the past decade, highlighting the recent emergence of this technology to tackle the plastic waste problem. A majority of patents arise from academia, where plastics recycling is a growing research topic. Although innovations for plastics hydrocracking have been reported, most of them disclose the use of catalysts in batch reactors, whereas very few patents describe the process. Continuous operation at pilot scale will be essential to gather process data towards industrialisation and further assess the commercial viability of theplastics hydrocracking technology.

Authors: Hofmann Sandra
Published: December 2023

The Ethics Series is a workshop tour on the wide-ranging topic of ethics in chemistry organized on a regular basis by the Platform Chemistry of the Swiss Academy of Sciences (SCNAT). The Ethics Series addresses all researchers in chemistry and has the aim to sensitize the audience for timely topics on issues such as the previously addressed topics of scientific integrity, social responsibility or overselling in publications. Internationally renowned speakers are invited to give a series of lectures at Swiss universities and federal institutes of technology, jointly with local speakers.
The format is similar to the "world café" style: short introductory lectures, break-out sessions to discuss specific topics, reports to the plenary followed by a discussion with audience participation. This year’s topic was on Recognizing and Overcoming Bias and took place from June 7 – June 9, 2023. Prof. Lee Penn and local panellists discussed a variety of questions arising around bias.
Supercritical CO2 as the carbon source and reaction medium for methanethiol synthesis in primordial subseafloor
Authors: Kitadai Norio , Shibuya Takazo , Ueda Hisahiro , Tasumi Eiji , Okada Satoshi , Takai Ken
Published: December 2023

Abiotic synthesis of methanethiol through CO2 reduction is a presumptive initiation reaction of protometabolism in primordial ocean hydrothermal systems. However, reported artificial means of methanethiol production indicate the necessity of gas-phase condition, rather than aqueous-phase setting, for this prebiotic reaction to occur. Here we demonstrate experimentally that this dilemma was mitigated by subseafloor supercritical CO2. Under supercritical CO2 with a geochemically feasible concentration of hydrogen, up to 7.9% conversion of hydrogen sulfide to methanethiol was achieved at 200 °C on molybdenum sulfide catalyst deposited in a carbonate-NaCl solution. Effective formations of carbon monoxide, methane, and formate were also observed. On the present ocean floor, discharges of liquid and supercritical CO2 occasionally occur in close vicinity to hydrothermal vents. Geological records of ancient seafloor suggest prevalence of such CO2 fluxes associated with hydrothermal activities. Our experimental results link these facts with the protometabolism scenario, leading to the possibility that the generation and transportation of methanethiol through the subseafloor CO2 fluxes constituted the beginning steps of protometabolism in primordial ocean hydrothermal systems. Thus, the supply of supercritical-CO2-derived materials likely directed the chemical evolution of life in combination with the known geochemical processes at the primordial ocean-vent interface.

Published: December 2023

To fill the need for environmentally sensitive fluorescent unnatural amino acids able to operate in the red region of the spectrum, we designed and synthesized Alared, a red solvatochromic and fluorogenic amino acid derived from the Nile Red chromophore. The new unnatural amino acid can be easily integrated into bioactive peptides by means of classical solid-phase peptide synthesis. The fluorescence quantum yield and the emission maximum of Alared-labeled peptides vary in a broad range depending on the peptide’s environment, making Alared a powerful reporter of biomolecular interactions. Due to its red-shifted absorption and emission spectra, Alared-labeled peptides could be monitored in living cells with minimal interference from cellular autofluorescence. Using ratiometric fluorescence microscopy, we were able to track the fate of the Alared-labeled peptide agonists of the apelin G protein-coupled receptor upon receptor activation and internalization. Due to its color-shifting environmentally sensitive emission, Alared allowed for distinguishing the fractions of peptides that are specifically bound to the receptor or unspecifically bound to different cellular membranes.
Cooperative Fe/Co Catalyzed Remote Desaturation for the Synthesis of Unsaturated Amide Derivatives
Authors: Wan Yanjun , Ramirez Emmanuel , Ford Ayzia , Zhang Harriet K. , Norton Jack R. , Li Gang
Published: December 2023

Unsaturated amides represent common functional groups found in natural products and bioactive molecules, serving as versatile synthetic building blocks. Here, we report an iron(II)/cobalt(II) dual catalytic system for the syntheses of distally unsaturated amide derivatives. The transformation proceeds through an iron nitrenoid-mediated 1,5-hydrogen atom transfer (1,5-HAT) mechanism. Subsequently, the radical intermediate undergoes hydrogen atom abstraction from the vicinal methylene by a cobaloxime catalyst, efficiently yielding β,γ- or γ,δ-unsaturated amide derivatives under mild conditions. The efficiency of Co-mediated HAT is tunable by varying different auxiliaries, highlighting the generality of this protocol. Remarkably, this desaturation protocol is also amenable to practical scalability, enabling the synthesis of unsaturated carbamates and ureas which can be readily converted into various valuable molecules.

Published: December 2023

The uncontrolled rise and spread of antimicrobial resistance (AMR) is one of the most severe and immediate threats to global health. Resistant infections are responsible for millions of deaths worldwide annually and current trends indicate that the issue will only aggravate in the future. Meanwhile, commercial drug development is dominated by incremental modifications of existing intellectual property instead of exploring novel therapeutic strategies with lower likelihood of resistance development. FabV is an enoyl acyl carrier protein reductase (ENR), a crucial component of the universal bacterial fatty acid biosynthetic pathway (FasII), that is found across several critical Gram-negative bacteria. This includes P. aeruginosa, an opportunistic pathogen associated with hospital infections. This pathogen co-expresses FabV along with its more frequently occurring isozyme FabI, and is therefore resistant to common FabI inhibitors. This study sought to investigate the rational, iterative design of paFabV inhibitors. A total of 44 compounds, based on the existing diaryl ether scaffold for ENR inhibition, were synthesized and screened in an enzymatic assay. This resulted in a potent inhibitor of FabV, RGB32, with an IC50 value of 0.59 ± 0.04 μM. The results of this work could serve as an encouraging starting point for further investigation of the therapeutic potential of FabV inhibition.
Oxygen Chemistry in Polymer Fouling: Insights from Multiphase Detailed Kinetic Modeling
Authors: Pang Hao-Wei , Dong Xiaorui , Green William H.
Published: December 2023

Polymer fouling is a pervasive challenge in downstream processes of steam cracking. Molecular oxygen is likely to present and known to strongly affect various polymerization processes, yet the role of oxygen in distillation column fouling remains poorly understood. Building upon the foundations laid in our preceding study [Pang et al., Ind. Eng. Chem. Res. 2023, 62, 36, 14266–14285], this work presents a detailed kinetic modeling approach to investigate the impact of oxygen on polymer fouling in a typical debutanizer. The fouling model incorporates molecular oxygen as a primary source of contamination in the feedstock and encompasses a comprehensive network of chemical reactions, phase equilibria, and interphase transport phenomena. Critical model parameters are derived from quantum chemistry calculations to ensure accuracy. The sensitivity of fouling rates to varying levels of dissolved oxygen is examined. We find that even small traces (ppb level) of molecular oxygen contaminant in the feedstock can significantly accelerate fouling growth in the colder section. Furthermore, the dominant pathways of fouling are observed to shift over time due to diffusion limitations. This study showcases the power and adaptability of predictive detailed kinetic modeling in deciphering the mechanistic fundamentals of polymer fouling.
A Prebiotic Selection of β-Furanoside-5'-Phosphate as the Sole Configuration toward the Synthesis of Extant RNA

Published: December 2023

The cause of the selection of β-furanoside-5'-phosphate as the backbone configuration of RNA during life’s origins has not been fully determined. Previous attempts were mostly unsuccessful in demonstrating either a selective synthesis or a selection mechanism for β-furanoside and 5'-nucleotide in the nucleosidation and phosphorylation steps. These questions are answered in this study. Inspired by the chromatographic elution order of nucleoside and nucleotide isomers, a unique separation mechanism has been established. It is discovered that β-furanoside is the most permeable configurational isomer across a lipid protomembrane as compared with other isomers, and becomes the most abundant isomer through permeation. In the meantime, phosphate can be transported across the lipid membrane and preserved inside the protocell in its soluble form, thereby circumventing its abundance and availability issues. The phosphorylation step is likely to take place intracellularly, where the formed nucleotide isomers are again screened by the lipid membrane via a reverse permeation, leaving 5'-nucleotide the enriched ribonucleotide species in the protocell for the upcoming transformations such as oligomerization. These findings depict a primitive selection mechanism driven by physicochemical forces to advance critical steps in molecular evolution, which could be one of the earliest protocellular functions.
Formation and Stability of μ2-Peroxo on Titanosilicates, Anatase and Rutile: Implications for Zeotype Catalysts

Published: December 2023

Extra-framework TiO2 in titanosilicate oxidation catalysts has generally been linked with low selectivity and great emphasis has been put on developing synthetic protocols that yield anatase-free materials. Here, using 17O solid-state NMR spectroscopy, we investigate the formation and stability of μ2-peroxo groups on both titanosilicates containing or not containing extra-framework TiO2 as well as TiO2 polymorphs. By comparison with TiO2 nanoparticle references, H2O2 activation (e.g. peroxo formation) and decomposition is proposed to be related to the presence of rutile-like extra-framework TiO2. In fact, μ2-peroxo species can form and remain stable on anatase, whereas they decompose quickly on rutile. According to DFT calculations, the high stability of μ2-peroxo surface species on anatase is due to the specific arrangement of μ2-oxo groups on the 101 surface that allows for stabilization of key-intermediates through H-bonding. Notably, the μ2-peroxo species formed on titanosilicates and anatase display distinct 17O NMR spectroscopic signatures, that relates directly to the Ti coordination environments, and can thus be distinguished.
Attitudes of Kurdish university students towards the English language, English language education policies, and English language learning purposes
Authors: Qadir Sarkawt , Omar Rukhsar
Published: December 2023

Similar to other parts of the world, Kurdish speakers of English have been subject to English fever. They have a strong desire to learn and speak English. An army of teachers is currently teaching Kurdish speakers to learn English. However, few of them acquire the required level of English when they move from high school level to university one. This might partly be associated with their attitudes towards not only the English language but the English language policies and practices that are currently adopted. Attitudes towards the English language have been extensively investigated both quantitatively and qualitatively in diversified educational and cultural contexts. Furthermore, a few studies have been conducted to investigate the attitudes of Kurdish students towards the English language, but their attitudes to English language education policies and English language learning purposes have yet remained unknown. Therefore, this study is anchored on investigating Kurdish undergraduate students’ attitudes towards the English language, English language education policies that are currently applied in Iraqi Kurdistan, and students’ purposes for learning English. It further concentrates on the effect of such variables as gender and year of study on attitudes. For this purpose, the study utilized a questionnaire consisting of 42 items on a 6-point Likert scale surveyed online on a sample of 154 students belonging to different ages, genders, years of study, and majors. The analysis of the data showed that Kurdish university students held neutral to mildly positive attitudes to the English language and English learning purposes. Nevertheless, they held slightly positive attitudes towards English language education policies. The study concludes that, although fundamental transformations have been achieved in the past two decades, the neutral attitudes show that efforts are yet to be made to satisfy students’ needs and desires, particularly with regard to the policies and practices that are currently adopted. This study, different from previous ones, reveals students’ attitudes towards English education policies whose findings are significant for English language education policymakers.

Authors: Brzeziński Kamil , Dorożyński Tomasz , Kretek-Kamińska Agnieszka , Marciniak Piotr
Published: December 2023

Przedmiot badań: Przedmiotem badania jest pojęcie reprezentatywności organizacji przedsiębiorców rozpatrywane z perspektywy różnych dyscyplin w obszarze nauk społecznych – socjologii, prawa i ekonomii.

Cel badawczy: Projektowanie i realizacja polityki gospodarczej wymagają istnienia efektywnych ram dialogu między instytucjami państwowymi i organizacjami reprezentującymi przedsiębiorców. By dialog ten miał charakter merytoryczny, konieczne jest uwzględnienie w nim reprezentatywnych przedstawicieli rynku. W języku prawnym pojęcie reprezentatywności zdefiniowane jest jednak wyłącznie w kontekście przepisów ustawy o Radzie Dialogu Społecznego, a członkami Rady jest jedynie sześć organizacji pracodawców. Podmiotów tych nie można uznać za reprezentatywne dla ogółu przedsiębiorców w Polsce. Wobec braku definicji legalnej o charakterze horyzontalnym głównym celem badania jest wskazanie warunków niezbędnych do uznania organizacji przedsiębiorców za reprezentatywną na gruncie nauk społecznych.

Metody badawcze: W opracowaniu dokonano przeglądu literatury socjologicznej, ekonomicznej i prawniczej. Wykorzystano metodę dedukcji i krytyczną analizę wybranych aktów prawnych.

Wyniki: Wyniki badań wskazują na potrzebę wypracowania – z wykorzystaniem narzędzi stosowanych na gruncie socjologii i statystyki – i wprowadzenia do porządku prawnego horyzontalnej definicji legalnej organizacji reprezentatywnej dla biznesu. Definicja taka precyzowałaby jedno- znacznie kryteria dostępu organizacji przedsiębiorców do procesów konsultacyjnych związanych z gospodarką oraz stanowiła podstawę do jednoznacznego zdefiniowania obowiązków konsultacyjnych po stronie publicznej. Autorzy wskazują ponadto, iż problem definicyjny wynika z braku powszechnego samorządu gospodarczego w Polsce, który ze swojej istoty byłyby instytucją reprezentatywną dla ogółu przedsiębiorców.

Authors: Umashankar Yaligar , Arun Koti , Shankar H. Sanni
Published: December 2023

Corrosion of steel is one of the major problems concerning construction field which becomes more severe when the structures are subjected to harsh environment which is harmful to structure as well as costs high for repair. Hence, deviating to alternate building materials is essential in upcoming years. One of the latest findings among them is replacement of steel with Glass Fiber Reinforced Polymer (GFRP) bars. Experimental and numerical studies on various strength parameters of these bars are being undertaken to examine their replacement to steel. This work contains experimental investigations on bond performance of Glass Fiber Reinforced Polymer (GFRP) bars. In the present study the bond behavior GFRP bars with and without wrapping of binding wire embedded in polypropylene fibers reinforced concrete and conventional steel rebar embedded in plain concrete was tested. The grade of concrete used for investigation was M40 and for bond testing 10, 12 mm diameter steel and GFRP bars were used in this experimental work. Pull-out test was conducted in Universal Testing Machine (UTM). It was observed that bond behavior of GFRP bar and concrete were lesser than steel bar by 41.06 % for 10 mm diameter bars and by 31.63 % for 12 mm diameter bars. Although it was observed that GFRP bar wrapped with binding wire possessed lesser bond stress than steel bars, it has improved bond stress compared to GFRP without wrapping by 16.06 % for 10 mm diameter bar and by 14.22 % for 12 mm diameter bars. Also maximum slippage was observed for GFRP than steel bar and GFRP with binding wire wrapping. GFRP bar slippage of 10 mm and 12 mm diameter is 130.88 % and 63.64 % and respectively higher than steel bars. The bond strength and maximum slippage of GFRP bar is found to be decreased with increase in diameter.
ЕФЕКТИВНІ ПРУЖНІ ХАРАКТЕРИСТИКИ ВОЛОКНИСТОГО КОМПОЗИЦІЙНОГО МАТЕРІАЛУ В УМОВАХ ПОПЕРЕДНЬОГО ПОПЕРЕЧНОГО ДЕФОРМУВАННЯ

Published: December 2023

У статті розглядається математичне моделювання механічної поведінки волокнистого композиту для визначення його напружено-деформованого стану в умовах попередньої деформації. Знайдено аналітичні співвідношення для ефективних характеристик волокнистого композиційного матеріалу, а саме модулів пружності та коефіцієнтів Пуассона, з урахуванням зміни об’ємного вмісту компонентів у процесі деформування. В роботі для визначення ефективних характеристик застосовується метод представницького об’ємного елементу. Розглянуто спільне деформування порожнистого та суцільного циліндрів, що моделюють, відповідно, матрицю та волокно у композиті, з урахуванням того, що осьові переміщення і волокна й матриці сталі й однакові. Вважається, що в процесі деформації і матеріал матриці, і матеріал волокна підкоряються закону Гука, але в процесі деформації їх об’ємна частка в композиті змінюється. Ця зміна буде визначатися зміною площі поперечного перерізу ділянок елементарної комірки, зайнятих матрицею і волокном, враховуючи, що висота нескінченної комірки буде однаковою для матриці і волокна. Отримано співвідношення для напружено-деформованого стану ізотропного волокна та матриці, в яких передбачається, що незважаючи на лінійний характер деформування матриці та волокна, об’ємна частка компонентів змінюється при збільшенні зовнішнього навантаження й впливає на деформований стан компонентів. Далі розглядається аналогічна задача для однорідного трансверсально- ізотропного матеріалу, що моделює поведінку композиційного матеріалу. Умовою узгодження для цієї задачі будуть виступати рівність осьових переміщень для довільної осьової координати та рівність радіальних переміщень на зовнішній частині циліндричної поверхні. Отримано аналітичні вирази для ефективних пружних характеристик при поперечному деформуванні із врахуванням зміни деформованого стану. Досліджено залежність ефективних характеристик від зміни об’ємного вмісту волокна в композиті в процесі деформування.

Las formas de la objetividad
Authors: López Álvarez Pablo
Published: December 2023

La relevancia teórica de G. Lukács no se limita a su peso en el denominado marxismo occidental. Su obra filosófica hasta Historia y consciencia de clase (1923) ofrece perspectivas singulares sobre la evolución de las formas sociales modernas, la posibilidad de su captura estética y epistemológica y los modos de acción individual y colectiva. La recepción de su obra en los pensadores de la inicial Teoría crítica (Adorno y Benjamin) permite ampliar la discusión en torno a las formas de interpretar el mundo cosificado y de transformarlo. La atención a los problemas de la objetivación, la cosificación y la segunda naturaleza tiene implicaciones para una ontología social y una teoría de la experiencia contemporáneas.

As análises espaço-temporais dos aspectos do uso e ocupação de determinados territórios, contribuem de maneira expressiva para subsidiar as ações de planejamento e ordenamento territorial, embasadas na visão sistêmica e integrada da Geoecologia das Paisagens. Sendo assim, o presente artigo aborda a análise espaço-temporal do município de Nova Russas, situado na porção oeste do estado do Ceará/Brasil, que ao longo dos anos apresentou modificações nas feições paisagísticas locais impulsionadas pela exploração e ocupação desordenada do território. Através da análise geoecológica, foram definidas cinco classes de uso e ocupação do município em diferentes períodos (1985 e 2011), as quais apresentaram variações expressivas. A partir dessas análises, observa-se que se o crescimento municipal mantiver-se no mesmo ritmo verificado na análise temporal, as atividades econômicas locais, a qualidade de vida da população e a disponibilidade dos recursos naturais serão afetadas, sendo indispensável à adoção de estratégias de gestão que orientem o crescimento e ordenamento territorial do município.

Historicamente a cidade do Recife concentrou em seu território unidades públicas de saúde em função da centralidade que ela exerce sobre as demais cidades da Região Metropolitana do Recife. Mas, a partir de 2010, a atual gestão do Governo de Pernambuco vem implantando, numa perspectiva desconcentradora da demanda, ação de expansão espacial das Unidades de Pronto Atendimento (UPAs), as quais vêm trazendo “inovações” ao campo da saúde pública, principalemente, no que tange à sua distribuição espacial. Diante desta realidade, temos como objetivo discutir a distribuição espacial dessas UPAs em relação aos assentamentos precários e à rede viária na RMR. Para tanto, foram confeccionados mapas georeferenciados no software Auto Cad 2007 a partir dos quais foi possível interpretar e discutir a localização espacial das UPAs frente as duas escalas consideradas. Assim, conclui-se que as UPAs em funcionamento estão distribuídas de modo a facilitar o acesso, principalmente, das populações pobres. A relevância deste ensaio se dá pelo esforço de pôr em discussão uma política pública de saúde que deveria garantir a universalização dos direitos de cidadania. A B S T R A C T Historically, Recife has concentrated public health units in its territory due to the importance of Recife on other cities in the Recife’s Metropolitan Region (RMR). But, the current management of the Government of Pernambuco has been deploying, at a perspective of distributing the demand, the action of spatial expansion of Emergency Units (UPAs), which have been bringing ";innovations"; to the public health field, mainly, with regards to their spatial distribution. In this context, we aim at discussing the spatial distribution of UPAs related to poor areas and roads in RMR. For that, georeferenced maps were made in Auto Cad 2007 software from which it was possible to interpret and discuss the spatial location of (UPAs) in two scales. Thus, it is concluded that the UPAs operating in RMR are distributed so that their access is facilitated, especially with regard to poor people. The relevance of this paper is given by discussion of de role of public health policy into the universal rights of citizenship.   Keywords: Emergency Units, Recife’s Metropolitan Region, Spatial Distributing.

No ano de 2010, o período compreendido pelos meses de junho a setembro foi marcado por uma fase seca principalmente na região norte central do Estado do Paraná. A baixa umidade do ar associada aos baixos índices pluviométricos registrados para esses meses permitiram levantar a hipótese de que as condições do tempo atmosférico que predominaram neste período poderiam ter influenciado na ocorrência e no agravamento de focos de incêndio. Para conduzir esta pesquisa, analisou-se durante os anos de 2009 e 2010 o comportamento de três elementos climáticos, sendo eles: umidade relativa do ar, precipitação e insolação. Utilizou-se o ano de 2009 como parâmetro de comparação, visto que o mesmo não apresentou, nos meses de junho a setembro, características climáticas semelhantes às apresentadas neste mesmo período em 2010. Esses elementos foram correlacionados com a quantidade mensal de incêndios combatidos pelo 1º Subgrupamento de Bombeiros (SGB) de Maringá. Dos resultados, pode-se concluir que, no período que compreende os meses de junho a setembro de 2010, a ocorrência de focos de incêndio registrou um número de aproximadamente 287% maior comparado ao mesmo período do ano de 2009, provando que as condições climáticas que marcaram este período favoreceram o agravamento destes eventos.   A B S T R A C T In the year 2010, the period among the months from June to September was marked by a drought period, particularly in the central north region of Paraná State. The low air humidity associated with low rainfall indices recorded for these months led to the hypothesis that the weather conditions that prevailed during this period could have influenced the occurrence and worsening of fires. To conduct this research we analyzed, during the years 2009 and 2010, the behavior of three climate elements, namely: relative humidity, precipitation and insolation. The year 2009 was used as parameter of comparison, since this year do not presented in the months from June to September, climatic characteristics similar to those given in the same period in 2010. These elements were correlated with the monthly amount of environmental fires fought by the 1st Subgrouping of Fire-fighter (SGB) of Maringá. It is concluded that, in the period among the months from June to September 2010, the occurrence of fires recorded a number, approximately, 287% higher, compared to the same period of 2009, proving that the climatic conditions that marked this period favored the aggravation of these events.   Keywords: fires, weather conditions, Maringá

Esta pesquisa buscou avaliar o comportamento dos fluxos de CO2 simulados pelo modelo de superfície SiB2, a partir da calibração de alguns parâmetros do modelo. O estudo foi desenvolvido em um sítio experimental de soja localizado em Cruz Alta no Rio Grande do sul. A validação dos resultados obtidos compreendeu a análise estatística dos fluxos simulados em comparação com os dados observados (obtidos pela torre micrometeorológica), a partir da calibração dos seguintes parâmetros: altura da base do dossel (Z1), altura do dossel (Z2), fração de cobertura vegetal (V), distribuição do ângulo foliar (XL), reflectância da folha viva no visível (αv,l), porosidade do solo (θs), profundidade individual das camadas (zdepth), expoente de umidade (bee), índice de área foliar (IAF), condutância estomática mínima (B) e temperatura crítica para a respiração foliar (trdm). No que tange o processo de calibração, verificou-se que este resultou em um melhor ajuste do fluxo de CO2 simulado, quando comparado ao obtido experimentalmente. A B S T R A C T This research evaluated the behavior of the simulated CO2 fluxes by the surface model SiB2, from the calibration of some parameters of the model. The study was developed in an experimental site of soybean located in Cruz Alta, Rio Grande do Sul. The validation of the results embraced the statistical analysis of the simulated fluxes in comparison to observed data (obtained by micrometeorological tower), from the calibration of the following parameters: canopy base height (Z1), canopy top height (Z2), vegetation cover fraction (V), leaf angle distribution (XL), live leaf reflectance in the visible (αv,l), soil porosity (θs), depth soil moisture layer (zdepth), soil wetness expoent (bee), leaf area index (IAF), minimum stomatal condutance (B) and critical temperature for leaf respiration (trdm). In regard to the process of calibration, was found that this one resulted in a better adjustment of the simulated CO2 fluxes than that one experimentally obtained.

Este trabalho tem como objetivo verificar as correlações de índices de detecção de mudanças climáticas dependentes da precipitação pluvial, na Amazônia Ocidental e analisar suas relações com a Oscilação Decenal do Pacífico (PDO), Oscilação Multidecenal do Atlântico (AMO) e anomalias de Temperatura da Superfície do Mar (TSM) nas regiões do Pacífico Niño 1+2, Niño 3, Niño 3+4, Niño 4, e nas regiões do Atlântico, Índice do Atlântico Norte Tropical (TNAI) e Índice do Atlântico Sul Tropical (TSAI). Utilizou-se uma série de índices de precipitação de 36 pontos de grades, no período de 1970 a 2001, provenientes de reanalise do projeto ERA-40 do European Center for Medium-Range Weather Forecasts (ECMWF), e de anomalias de TSM e oscilações climáticas, PDO e AMO, disponíveis no site do NCEP (National Centers for Environmental Prediction). Realizou-se a correlação (coeficiente de correlação de Pearson) entre as anomalias de TSM e a média aritmética anual dos 36 pontos de grade de cada índice. Observou-se que as regiões do El Niño apresentaram uma fraca influência sobre a precipitação total da região estudada. O Índice simples de intensidade diária (SDII) apresenta forte correlação com o TSAI, mostrando que este índice é bem afetado pela variabilidade da TSM do Atlântico Sul. Portanto. Compreende-se que os índices de extremos climáticos da Amazônia Ocidental são influenciados pelas oscilações interdecenais. A B S T R A C T This work aims to study the relationship of detection rates of climate change dependent on rainfall in Western Amazon and analyze their relations with the Pacific Decadal Oscillation (PDO), Multidecadal Atlantic Oscillation (AMO) and surface temperature anomalies Sea (SST) in the Pacific regions Niño 1 +2, Niño 3, Niño 3 +4, Niño 4, and regions of the Atlantic, Tropical North Atlantic Index (TNAI) Index and the Tropical South Atlantic (TSAI). We used a series of rainfalls of 36 grid points in the period 1970-2001, from reanalysis project ERA-40 from the European Centre for Medium-Range Weather Forecasts (ECMWF), and SST anomalies and fluctuations climate, PDO and AMO, available on the website of the NCEP (National Centers for Environmental Prediction). We conducted correlation (Pearson correlation coefficient) between the SST anomalies and the annual arithmetic mean of 36 grid points of each index. We observed that the regions of the El Nino showed a weak influence on the total precipitation of the studied region. The simple daily intensity index (SDII) has a strong correlation with TSAI, showing that this ratio is much affected by the variability of the South Atlantic SST So. It is understood that the indices of climate extremes in western Amazonia are influenced by fluctuations interdecadais. Keywords: Climate variability, climate change, climate indices.
