MEGAGEOMORFOLOGIA DO NOROESTE DO ESTADO DO CEARÁ
Authors: Claudino-Sales Vanda , Lira Maria Valdete 
Published: November 2022

A área de estudo localiza-se a noroeste do estado do Ceará, situada em um mosaico geológico e geomorfológico com características distintas. Trata-se do front norte da "Serra da Ibiapaba", que corresponde à escarpa da bacia sedimentar paleozóica do Parnaíba, dominada pela Formação Serra Grande. Na área também ocorre o "Sistema Médio Coreaú", que corresponde a estruturas pré-cambrianas parcialmente arrasadas pela erosão, contendo porém elementos geomorfológicos importantes, os quais conferem elevada movimentação aos terrenos. Essas estruturas passaram por longa evolução, em particular (1) nas fases do Ciclo Orogenético Brasiliano, ao final do Pré-cambriano, que colou o Brasil Ã Àfrica, gerando o megacontinente Panótia e produzindo extensas áreas dobradas e falhadas, acompanhadas de metamorfismos regionais e magmatismos, (2) na divisão do megacontinente Panótia, no início do Paleozóico, que resultou na formação da bacia sedimentar do Parnaíba, (3) na reativação tectônica cretácea, particularmente associada à divisão do Pangea, que soergeu os terrenos na forma de ombros de rift e (3) no Cenozóico, a partir da ação de processos erosivos comandados por climas secos. O resultado de tal processo evolutivo originou a Serra (glint) da Ibiapaba, a Depressão Sertaneja adjacente, do tipo "depressão periférica", e maciços cristalinos residuais. À exceção do topo do Glint da Ibiapaba, as demais localidades são fracamente povoadas, em razão da existência de vertentes muito íngremes e solos pouco desenvolvidos, o que empresta um caráter essencialmente natural Ã área de estudo.

Published: November 2022

As secas severas no nordeste do Brasil, objeto de inúmeros estudos por seus impactos sociais e econômicos, têm sido relacionadas Ã ocorrência do El NiÃ±o. A finalidade principal deste trabalho é verificar as escalas temporais e os mecanismos meteorológicos que exercem influência sobre a variabilidade pluviométrica das sub-bacias do rio Jaguaribe. O teste de Mann-Kendall será utilizado neste trabalho com o objetivo de detectar tendências hidroclimáticas nas séries pluviométricas da bacia hidrográfica do rio Jaguaribe (Ceará/Brasil) e assim, gerar informações que podem auxiliar os setores ligados aos recursos hídricos. Foram utilizados dados de precipitação obtidos através da Agência Nacional das Águas para o período de 1921 a 2010. De acordo com o IAC anual detectou-se que a predominância de anos secos ocorre em toda a bacia do rio Jaguaribe. Os resultados das Análises de Ondeletas indicaram que principalmente a variabilidade sazonal, interanual ligada ao ciclo de ENOS e a variabilidade decadal influenciaram na variabilidade pluviométrica de toda a bacia hidrográfica.

Published: November 2022

Este artigo teve como objetivo elaborar um mapeamento hidrográfico de detalhe e análise morfométrica comparativa das bacias dos rios Tijuípe e Tijuipinho, situadas no litoral sul da Bahia. Para tal, foram realizadas análises por meio de fotointerpretação, sensoriamento remoto e pesquisas de campo, nos quais restituímos as redes hidrográficas e delineamos os divisores de água das bacias, processando estas informações em um Sistema de Informação Geográfica (SIG), que utilizamos na edição dos mapas e na leitura digital dos dados lineares, de superfície e altimétricos. No geral, constatou-se que a área da bacia do Tijuípe é de 74,66 km2, enquanto que a área do Tijuipinho é de 41,27 km2 e possuem densidade de drenagem de 3,74 km de canais/ km² para a bacia do Tijuípe e 2,67 km de canais/ km² para a bacia do Tijuipinho. Constatou-se que as bacias estudadas possuem formas relativamente alongadas, influenciadas pelos lineamentos estruturais da região que determinaram a formação de dois vales paralelos, o do Tijuípe e do Tijuipinho, na direção SO-NE. Conclui-se que a abordagem apresentada tenha o potencial de orientar a demarcação de importantes mananciais e de áreas de recarga dos aquíferos, bem como a delimitação de áreas sujeitas a desequilíbrios morfodinâmicos.

Akumulasi mikroplastik di lingkungan menimbulkan ancaman ekologis dan telah menjadi masalah serius di dunia. Plastik terdistribusikan secara global di lautan dunia tersebar di kolom air, permukaan air, sepanjang garis pantai dan pada sedimen. Salah satu strategi untuk menghadapi pencemaran mikroplastik yaitu mencari agen pendegradasi mikroplastik berupa mikroba. Mikroba yang memiliki aktivitas pendegradasi terhadap polimer biasanya dapat diuji untuk mendegradasi plastik. Sumber alami untuk mendapatkan mikroba potensial yang memiliki aktivitas pendegradasi bisa didapat dari organisme yang memiliki banyak bakteri endosimbion untuk hidup seperti Mangrove. Sehingga perlu kajian mengenai potensi bakteri simbion mangrove dalam mendegradasi plastik. Uji degradasi mikroplastik polyethylene menggunakan mangrove Avicennia marina telah mendapatkan beberapa isolat agen biodegradator mikroplastik yaitu isolat WB-12, PJ-01 dan PJ-02 yang telah diketahui memiliki aktivitas biodegradasi pada mineral salt media polyethylene. The accumulation of microplastics in the environment poses an ecological threat and has become a serious problem worldwide. Plastics are distributed globally in the world's oceans scattered in the water column, water surfaces, along coastlines and in sediments. One strategy to deal with microplastic pollution is to look for microplastic degrading agents in the form of microbes. Microbes that have polymer-degrading activity can usually be tested for plastic degradation. Natural sources to obtain potential microbes that have degrading activity can be obtained from organisms that have many endosymbiont bacteria to live such as mangroves. So it is necessary to study the potential of mangrove symbiont bacteria in degrading plastic. Polyethylene microplastic degradation test using Avicennia marina mangrove has obtained some of the microplastic biodegradator agents, namely isolate WB-12, PJ-01 and PJ-02 which is known to have biodegradation activity in mineral salt media polyethylene.
Estimasi Serapan Karbon Pada Vegetasi Mangrove Register 15, Kecamatan Pasir Sakti, Kabupaten Lampung Timur, Provinsi Lampung
Authors: Kusuma Anma Hari , Effendi Eko , Hidayatullah Maulana Syarif , Susanti Oktora 
Published: November 2022

Perubahan iklim di sebabkan oleh kenaikan gas karbon dioksida (CO2) semenjak era revolusi industri dimana hal ini dicirikan dengan adanya peningkatan suhu, paras muka laut, perubahan pola curah hujan serta meningkatnya kejadian ekstrim seperti banjir, kekeringan, gelombang panas dan badai. Fenomena ini akan berdampak serius apabila berlangsung secara terus-menerus. Blue carbon (karbon biru) merupakan karbon yang diperangkap dan disimpan melalui proses fotosintesis oleh organisme autotrof dalam bentuk biomassa dan sedimen oleh ekosistem pesisir dan laut. Mangrove merupakan salah satu dari eksosistem sebagai blue carbon tersebut. Mangrove Register 15 merupakan suatu kawasan mangrove yang berada Kecamatan Pasir Sakti, Kabupaten Lampung Timur, Provinsi Lampung. Penelitian ini bertujuan menganalisis karbon tersimpan pada tegakan, nek romassa, serasah, dan substrat mangrove. Penelitian dilakukan dari bulan Maret–Mei 2021. Hasil penelitian menunjukkan karbon tersimpan pada sedimen lebih besar dibandingkan dengan karbon tersimpan pada tegakan, nekromassa, dan serasah. Karbon tersimpan pada sedimen yang tertinggi berada pada sedimen yang memili ki ukuran liat kasar karena liat kasar dapat menyimpan unsur hara yang tinggi. Climate change is caused by an increase in carbon dioxide (CO2) gas since the industrial revolution era where it is characterized by an increase in temperature, sea level, changes in rainfall patterns and increased extreme events such as floods, droughts, heat waves and storms. This phenomenon will have a serious impact if it continues. Blue carbon is carbon that is trapped and stored through the process of photosynthesis by autotrophic organisms in the form of biomass and sediment by coastal and marine ecosystems. Mangroves are one of these ecosystems as blue carbon. Mangrove Register 15 is a mangrove area located in Pasir Sakti District, East Lampung Regency, Lampung Province. This study aims to analyze the carbon stored in stands, nec romassa, litter, and mangrove substrates. The study was conducted from March–May 2021. The results showed that carbon stored in sediments was greater than carbon stored in stands, necromass, and litter. The highest carbon stored in sediments is in sediments that have the size of coarse clay because coarse clay can store high nutrients.
Is the prognosis of non‐hypertensive, COVID‐19 patients treated with renin–angiotensin–aldosterone system inhibitors more uncertain?

Published: November 2022

AbstractPrevious studies suggested that ongoing treatment with renin–angiotensin–aldosterone system (RAAS) inhibitor drugs may alter the course of SARS‐CoV‐2 infection and promote the development of more severe forms of the disease. The authors conducted a comparative, observational study to retrospectively analyze data collected from 394 patients admitted to ICU due to SARS‐CoV‐2 pneumonia. The primary aim of the study was to establish an association between the use of RAAS inhibitor drugs and mortality in the ICU. The secondary aims of the study were to establish an association between the use of RAAS inhibitor drugs and clinical severity at ICU admission, the need for tracheal intubation, total days of mechanical ventilation, and the ICU length of stay. The authors found no statistically significant difference in ICU mortality between patients on RAAS inhibitor drugs at admission and those who were not (31.3% versus 26.2% mortality, p‐value 0.3). However, the group of patients taking RAAS inhibitor drugs appeared to be more critical at ICU admission, and this difference became statistically significant in the subgroup of non‐hypertensive patients. ICU mortality in the subgroup of non‐hypertensive patients treated with RAAS inhibitor drugs also tended to be higher. Overexpression of the angiotensin‐converting enzyme 2 (ACE2) in human cells, induced by RAAS inhibitor drugs, promotes viral entry‐replication of SARS‐CoV‐2 and alters the basal balance of the RAAS, which may explain the findings observed in the present study. These phenomena may be amplified in non‐hypertensive patients treated with RAAS inhibitor therapy.
Szene im Kirschgarten: Zu einem Gedicht von Paul Celan, mit einem methodologischen Exkurs
Authors: Corbea-Hoisie Andrei 
Published: November 2022

Abstract
The reconstruction of the creation of Paul Celan’s posthumous poem “In meinem zerschossenen Knie” enables an examination of the complex network of elements of his own biography – the traces of formative readings, his identity questions projected in his positions towards Judaism and Zionism, the obsessional poetic motives etc. – from which the poet lets the lyrical text ‘coagulate.’ The relationship between the author’s genetically anticipated ‘message’ and the hermeneutic freedom in the interpretation of Celan’s poetry is also considered.
Beyond Thought’s Limits: Celan, Heidegger, and the Crooked Path of Art
Authors: Rahamim Asif 
Published: November 2022

AbstractIn this article I contend that Paul Celan’s poem, “Todtnauberg,” written as a follow up to his visit to Martin Heidegger’sBerghütte, should be read not only as a challenge to Heideggerian philosophy’s fundamental assumptions – primarily the notion of dwelling in the world via poetic language – but also to the very structure of philosophical thought, with its biases and inadequacies. Drawing on Celan’s idiosyncratic use of the termVerjudungI show its centrality in understanding the poem’s deconstructive move, as it applied to the binaries inherent to Heideggerian thought: pure/impure, indigenous/foreign, rooted/uprooted, and authentic/inauthentic. Posing the deconstructive qualities of the poetic against the crude decisiveness of philosophical thought, I argue that “Todtnauberg” ‘catches’ Heideggerian thought unprepared, as it presents it with its own blind spots, misconceptions, and loose ends, and thus rattles the very ground in which it seeks to ground itself.
An Aesthete in Despair: Reading Lolita through Kierkegaard’s Aesthetic Sphere of Existence
Authors: QotbAbadi Alireza Safari , Hashemi Mahsa 
Published: November 2022

Abstract
Since its publication in 1955, Vladimir Nabokov’s contentious novel Lolita has stirred heated controversies that originated from Nabokov’s treatment of a thorny subject matter. What makes his achievement so stupendous is that he penned a book about a forbidden desire and succeeded in persuading his reader to feel for the deviant. The present study intends to fathom Nabokov’s success in his art of deception drawing on Søren Kierkegaard’s existentialist ideologies of aestheticism and despair in order to offer a new insight regarding the elements used in Humbert’s narration and character which bestow upon him the distinctive personality of the aesthete. Referring to Kierkegaard’s spheres of existence introduced in his “Either/Or,” it is suggested that Humbert, similar to Kierkegaard’s Johannes, aesthetically alienates himself from commitment and consequence while keeping an eye open for the interesting and relishing sensual immediacy. It is this shrewd aestheticizing of Humbert’s character that grants him his unique status that has elicited both attraction and aversion.
Constitutional Courts’ Helpdesk: The Venice Commission’s Advisory Role in Constitutional Adjudication
Authors: Yolcu Serkan 
Published: November 2022

Abstract
This article aims to analyse how constitutional courts make use of advisory opinions of the European Commission for Democracy through Law (Venice Commission). Despite that national constitutional courts significantly engage with the advisory work of the Venice Commission, the causes and effects of this engagement remain less explored in constitutional law scholarship. In order to address this gap, this article, from a macro perspective, examines the case law in which the Venice Commission is referred to by constitutional courts, drawn from the Venice Commission’s constitutional adjudication database (CODICES). In addition, appropriate data from the case law of the Constitutional Court of Turkey is examined in particular to expand the scope of the research through micro lens. The article argues that constitutional advice has some advantages for constitutional judges given that it provides a strategic tool for determining reasoning. Despite its non-binding nature, the Venice Commission’s constitutional advice is occasionally considered by constitutional courts, depending on the strategic preferences of the courts, and the judges in a given jurisdiction.
