Administração e sociedade: uma análise quanto às relações estabelecidas pelas instituições de poder e a garantia de liberdade baseada nos direitos civis e políticos em cenários internacionais.
Authors: Fonseca Almir , Silveira Gabriel
Published: September 2022

Neste presente artigo iremos estudar a relação entre os direitos civis e políticos e o tipo ideal do Estado Liberal de Direito. Segundo a concepção do filósofo Rousseau, o Estado é equiparado a uma pessoa, um corpo social em que se concretiza a vontade comum, ou seja, a vontade verdadeira e substancial de todos, contra a qual não podem prevalecer pretensões transviadas por motivos acidentais. Para tanto, analisaremos também os níveis de liberdade, no que se refere aos direitos civis e políticos, dos EUA, Frnaça, e Inglaterra como base no estudo Freedom In The World - Liberdade no Mundo.

Exploring Harm Reduction in Supportive Housing for Formerly Homeless Older Adults
Authors: Nixon Lara L. , Burns Victoria
Published: September 2022

Background
Exclusionary care policy contributes to the growing number of older adults experiencing homelessness and complex health challenges including substance misuse. The aim of this study was to examine how harm reduction policy and practices are experienced and enacted for older adults with homeless histories and care staff in congregate supportive housing.
Methods
Drawing on harm reduction (HR) principles, Rhodes’ risk environment framework, and 15 semi-structured interviews (six residents, nine staff) at a 70-bed supportive housing facility in Western Canada, this qualitative constructivist grounded theory study aimed to determine: How is harm reduction experienced and enacted from the perspectives of older adults and their care staff?
Results
HR policy and practices helped residents to feel respected and a sense of belonging, due largely to staff’s understanding of structural vulnerability related to homelessness and their efforts to earn and maintain residents’ trust. Physical and program structures in the facility combined with the social environment to mitigate harms due to substance- and nonsubstance-related risk behaviours.
Conclusion
HR policy and practices in supportive living empower care providers and older adults to work together to improve housing and health stability. Wider adoption of HR approaches is needed to meet the needs of a growing number of older people experiencing homelessness and substance use challenges.

Published: September 2022

Background: Periventricular/intraventricular hemorrhage (PVH/IVH) has a major impact on neurodevelopment due to its complications and sequelae. Objectives: This study aimed to determine the frequency of neurosonographic examination and the length of the monitoring period in children diagnosed with PVH/IVH. Methods: This clinical observational analytical retrospective cohort study was performed on 102 children diagnosed with PVH/IVH. The examinations were done on the third, seventh, fourteenth, and twenty-first days after birth and then in the fourth and sixth weeks and the third and sixth months after birth. The results of the examinations performed over time were subjected to the kappa measure of agreement test, with a significance threshold of 0.05, to determine the period when the most significant changes occur in the patient’s condition, as well as to determine the optimum frequency of the examination. Results: There was statistically significant agreement between the results of all the examinations performed in the observed moments (P < 0.0005). However, it is indicative that the agreement was excellent for the fourth week (kappa agreement was more than 0.85), followed by the sixth week that was very good (kappa agreement was 0.79); however, the agreement for the sixth week and the third month was very small (kappa agreement was less than 0.1). Also, there were no major changes (kappa agreement between results from the third and sixth months was 0.88). Conclusions: The first neurosonographic examination should be conducted in the first 7 days after birth, and the control examination should be conducted at the age of 4 - 6 weeks. If a pathological finding is observed, the examination is repeated after the specified period until a stationary finding is observed. After the third month, no new changes in the finding are observed.

Published: September 2022

Background: There has been a substantial shift in the educational curriculum in Indian medical institutes with a more experiential approach toward teaching. One such method is case-based learning (CBL). Objectives: This study aimed to compare CBL with traditional method and gain students’ and teachers’ feedback. Methods: This was a cross-sectional study conducted in the Pathology Department among second-year bachelor of medicine and bachelor of surgery (MBBS) students. The students were divided into two groups of 75 students: group A was given anemia cases, and group B was given jaundice cases. After covering theory lectures on these topics, the students were given pre-test multiple-choice questions (MCQs). This was followed by this was followed by subdividing students into five groups and conducting three CBL sessions. This was followed by post-CBL test. Data were compared using paired t-test and analyzed using SPSS software version 16. Results: Out of 150, 110 students attended the pre-and post-CBL test and completed the feedback form. There was a significant improvement (P < 0.001) in the mean scores of students in both groups A and B from 8.31 and 7.54 to 13.44 and 12.71, respectively. Regarding the student feedback, it was revealed that 87% of the students agreed with the usefulness of CBL in better understanding of the topic and retention in memory. They also acclaimed that it encouraged their critical thinking and decision-making qualities. Among the faculties, all of them agreed with the incorporation of CBL in the routine curriculum. Conclusions: CBL improves students’ logical, analytical and clinical skills, which helps bridge the gap between theoretical knowledge and clinical skills. Rather than replacing, it serves better as an adjunct to the traditional lectures.
Interspecific differences in desiccation tolerance of selected Antarctic lichens: Analysis of photosystem II effectivity and quenching mechanisms
Authors: Puhovkin Anton , Bezsmertna Oleksandra , Parnikoza Ivan
Published: September 2022

Lichens can survive and cope with unsufficient water supply resulting in low intrathalline relative water content. Under such conditions, photosynthesis is negatively affected by different degree of dehydration. In our study, fully hydrated samples of Xanthoria elegans, Umbilicaria decussata and Usnea aurantiaco-atra were light-acclimated and during following desiccation from a fully hydrated to dry state, steady-state chlorophyll fluorescence (FS), effective quantum yield of photochemical processes in PSII (ФPSII), and nonphotochemical quenching (qN) were measured in response to decreasing relative water content (RWC). The three experimental lichen species showed a high desiccation tolerance. The desiccation-induced decrease in ФPSII was found in X. elegans, U. decussata and U. aurantiaco-atra, at the RWC values below 30%. This is well comparable to the evidence reached in other Arctic / Antarctic lichen species. Interspecific differences in desiccation tolerance of these selected Antarctic lichens, based on the analysis of photosystem II effectivity and quenching mechanisms, were described and discussed.

Authors: Canora Diana Darriba , Guasch Laura Llorens , Zuazo Rebeca Sicilia
Published: September 2022

We studied the changes in PSII photochemical processes in the cells of Antarctic algae Klebsormidium sp. and Stigeoclonium sp. exposed to salinity stress (0 – 3M NaCl) for 3 h. Salinity stress induced a decrease in the potential (FV/FM) and effective quantum yield of PSII electron transport (FPSII). Salinity stress induced a decrease in vitality index (Rfd, relative decrease of chlorophyll fluorescence). Analyses of the polyphasic fast chlorophyll fluorescence transients (OJIP) showed that with the increase in salt concentration, the chlorophyll fluorescence signals recorded at the phases J, I, and P declined, and the transient flattened with increaseing NaCl concentration reaching close to zero ChlF values at salt concentration of 3 M NaCl after 180 min. exposition. Klebsormidium sp. was found more salinity stress resistant than Stigeoclonium sp.

Is your higher obligation to society or to your family? Does the outcome of your choices effect their rightness, and if you should take them? In this work of philosophical short story fiction set at a fictional University, Paul is pre-tenure in his duties and hears from a friend, who heard it from a “very reliable source” that one of the more senior professors was caught selling grades for sex. Rather than being exposed, and fired, they are helping him find a job at another nearby University. Paul is upset and this, and his wife is outraged, and insists they must do something to bring the professor to justice and keep it from happening again in the future. They call the newspaper, but because they are unable to provide concrete information, and refuse to provide their own names, the newspaper doesn’t pursue the story. The professor is transferred and, years later, retires as Dean of his department. Paul hears through the grape-vine that one of the alleged victims committed suicide.

Authors: Kumar Kamalakannan
Published: September 2022

Introduction Knowledge, attitude and precautionary measures regarding COVID-19 among mothers play an important role in reducing the spread of the infection and helping control the pandemic. It also provides insight into the role of the media in controlling the pandemic. Objective To assess knowledge, attitude and precaution measures (KAP) regarding COVID-19 among mothers in a tertiary care hospital. Methodology This was a questionnaire-based cross-sectional study regarding COVID-19 which was conducted at a tertiary care obstetric facility in India among 100 consenting mothers. The consenting mothers were assessed for demographic data and KAP scores (Knowledge - 8 questions, Attitude - 7 questions, Precautionary measures - 5 questions). Results A total of 100 mothers participated in the study. 21% of the mothers were less than 25 years of age, 67% of them were between the ages of 25 and 29 and the remaining 12% were between the ages of 30 and 35. The participants were asked to fill out a questionnaire on COVID-19 from which their knowledge was assessed. Common questions were about the type of disease, the mode of transmission and the symptoms. Concerning the current stage of distribution of COVID-19, the majority of the mothers stated that it was a pandemic (81%). Regarding the type of disease, the majority of the mothers stated that it was a communicable disease (79%). When enquired about the symptoms of the disease, the majority of the mothers stated fever (97%), cough (98%), and breathlessness (97%). All of the mothers (100%) agreed that the delivery of the baby should be performed at a hospital if they contracted COVID-19. Conclusion This study demonstrates that the majority of the mothers had satisfactory knowledge, a positive attitude and were applying appropriate precautionary measures to protect themselves from COVID-19.
Splinter haemorrhages as possible signs of myocardial infarction or pulmonary embolism
Authors: Đorđević Stefan , Anđelić Slađana
Published: September 2022

Introduction/Objective Subungual splinter haemorrhages (SSH) are a common non-specific clinical sign which is easy to recognize. They can occur in conjunction with many medical conditions of various significance. They present as painless black longitudinal lines towards the distal part of the nail bed. The objective of this article is to present a patient with newly acquired chest pain, a differential diagnostic dilemma between acute myocardial infarction (AMI) and pulmonary embolism (PE) whose fingers show signs of SSH. Case report An emergency medical team (HMP) was dispatched to a location where a 58-year-old man was experiencing chest pain. They found the patient in a sitting position, reporting sudden onset of stabbing chest pain with no propagation and lasting a few hours. He stated that he had never before had similar symptoms. Upon examination, the patient was afebrile, hypertensive (180/100 mmHg), mildly tachycardic (84/min), and blood oxygen saturation was within normal limits (97% on room air). ECG: sinus rhythm, left axis deviation, S1 in D1, ST elevation ≤ 1mm in D2, D3 and aVF, ST depression from V4 to V6. The physical examination revealed SSH located on the nail beds of the hands distally. The patient was transported to cardiology where he was continuously monitored. Rising values of troponin T (310, 2628, 1507 ng/l) and creatine kinase (934, 1228 U/l) were noted. However, based on the rising values of D dimer and pulmonary artery multislice computer tomography (MSCT) findings, there were reasons to consider the possibility of pulmonary embolism (PE) as well. Conclusion Future research should aim at defining the connection between SSH and AMI and/or PE. This would be crucial in making a prehospital diagnosis, especially in countries that have huge cardiovascular disease public health problems, such as ours. A quick and simple exam of nailbeds on the hands of patients with symptoms of AMI/PE, but without significant ECG findings, could help with the differential diagnosis if SSH were found to be present.
Anaesthetic management of Moyamoya disease in a six-year-old child: Anaesthetic management of Moyamoya disease
Authors: Singhal Shubhi , Banerjee Neerja , Bharti Devang , Kaur Mohandeep
Published: September 2022

Introduction: Moyamoya disease is a rare form of the chronic cerebrovascular disorder. Patients develop progressive stenosis or occlusion of the terminal portion of the internal carotid arteries and a proximal portion of the anterior and middle cerebral arteries. The compensatory collateral circulation that develops is weak and small, prone to hemorrhage, aneurysm, and thrombosis. Case Report: We report a case of a six-year-old boy with Moyamoya disease, presenting with complaints of seizures and weakness of the left side of the body. A bilateral encephalo-myo-synangiosis (EMS) was successfully performed on the child under general anesthesia without any perioperative complications. Conclusion: Revascularization surgery in a patient with Moyamoya disease is a high-risk procedure with an increased incidence of perioperative neurological sequelae. However, patients can be successfully perioperatively managed by ensuring adequate cerebral blood flow and minimizing cerebral metabolic oxygen consumption rates.
A prospective, randomized, double-blind, comparative study of phenylephrine and ephedrine in treating hypotension during cesarean section under spinal anesthesia: Vasoconstrictors for Hypotension During CS
Authors: Singh Jyoti , Bharti Devang , Gill Sharma , Singhal Shubhi
Published: September 2022

Introduction: Hypotension may affect 70-75% of patients undergoing cesarean section (CS) under spinal anesthesia (SA) and may have detrimental effects on both the mother and the fetus. Our study attempts to compare the effectiveness of phenylephrine and ephedrine in treating SA-induced hypotension in CS and their impact on the fetus. Methods: Forty adult pregnant female patients undergoing elective CS under SA were randomly divided into two groups to receive phenylephrine 100 µg IV bolus and ephedrine 6 mg IV bolus when the systolic blood pressure (SBP) dropped below 20% of the baseline. After delivery of the fetus, the umbilical artery blood sample was taken for blood gas analysis. Apgar score was recorded at 1 and 5 minutes post-delivery. Results: Significant differences were observed in heart rate (HR), SBP, and diastolic blood pressure (DBP), with HR being lower and SBP and DBP being higher in the Phenylephrine group. No significant difference was seen in the Apgar scoring, but uterine artery pH was significantly higher in the Phenylephrine group. Conclusion: Phenylephrine and ephedrine are equally effective in treating SA-induced hypotension in patients undergoing CS. Neonates of patients receiving phenylephrine had significantly higher pH than those receiving ephedrine, although the eventual neonatal outcome, as assessed by Apgar scoring, remained equally good with both drugs.
The protective effect of magnetic fields on the corrosion of aluminium alloys in hydrochloric acid solutions
Authors: Maurice Mejeha , Bierechi Okeoma , Agoh Uchechi , Chukwuebuka Igweze , Tamadu Obi
Published: September 2022

The effect of applied magnetic fields on the corrosion of aluminium alloys AA3003 and AA8011 in hydrochloric acid solutions at room temperature has been investigated by using the gravimetric technique. The magnetic fields were generated from a locally made electromagnet with variable outputs. They were applied at right angles to the surfaces of the aluminium alloy samples when completely immersed in the test solutions. The corrosion rates of the aluminium alloys AA3003 and AA8011 in 0.5M HCl acid solutions were monitored at different applied magnetic fields. Results show that the corrosion rates of the aluminium alloy samples studied decrease with increase in the applied magnetic field. This implies that the presence of magnetic field inhibits the corrosion of the aluminium alloy AA3003 and AA8011 samples. With applied magnetic fields in the range of 254.3 - 1040.6 mG [0.0254 - 0.1041 mT], the protection efficiency of the magnetic field observed for AA3003 in 0.5M HCl acid solutions ranges from 19.3 - 94.1% while for aluminium alloy AA8011 in identical test solutions, the protection efficiency ranges from 11.5 - 78.0%. The protection mechanism is attributed partly to the phenomenon of transverse magnetoresistance and partly to effect of the magnetic fields on the mass transport pattern of constituent ions in the electrochemical system.

The corrosion resistance of mild steel (used to make hull plates in ship technology) in seawater before paint coating (Nippon paint, weatherbond advance) and after paint coating has been measured by electrochemical studies such as Polarisation study and AC impedance spectra. It is observed that after paint coating, the corrosion resistance of mild steel hull plates increases. Polarization study reveals that after paint coating, the linear polarization resistance increases and corrosion current decreases. AC impedance spectra reveal that in the presence of paint coating charge transfer resistance value increases, impedance value increases, phase angle increases and double layer capacitance value decreases.
Frikommuner: Idéen der hverken vil dø eller slå an
Authors: Christensen Jørgen Grønnegård
Published: September 2022

Frikommuneidéen opstod i 1980’erne, og den har ikke forladt os. Regering efter regering har lanceret sin version af en verden, hvor kommunerne opnår mere selvstyre. Dette essay anlægger en kritisk vinkel på de dansk-nordiske erfaringer med frikommuneforsøgene og konkluderer ikke uden beklagelse, at kommunerne egentlig godt kan finde ud af styre egne anliggender. Men de får fortsat ikke lov. Lidt bittert kan man således konstatere to ting: Det er populært at regelforenkle, men umuligt at gøre det i praksis, og den generaliserede tillid til andre, som bar et af forsøgene, holder ikke i mødet med hverdagens nationale politik.
Debureaucratization of child welfare services in three free communes: A case-based analysis and discussion
Authors: Jensen Hanne Louise Søgaard , Strandby Martin Williams
Published: September 2022

This article analyzes and discusses a case of successful debureaucratization; the free-commune experiments regarding child welfare services from 2017-2020 where three Danish municipalities were allowed to replace key provisions in the social laws stipulating how to perform social work and administer social cases, with newly developed forms of social work. The analysis starts from the trifecta of rule exemptions, employee motivation and managerial focus, and shows – based on repeated survey data and qualitative interviews – how each of the three has materialized in this “debureaucratization success”. Furthermore, we discuss the relation between the three components. We argue that rule exemptions are significant as a launch-pad for changing how social work is done locally, via unleashing managerial focus and employee motivation. Rule exemptions appear almost redundant, since the largest debureaucratizing changes happen via the initiated change processes, where managerial focus appears to play a decisive role.
Fractales y suturas craneanas: nota de contrarréplica a Martín Escorza.
Authors: Palmqvist Paul , Gibert Josep
Published: September 2022

Los comentarios y críticas efectuadas par el Dr. Carlos Martin Escorza en relación con el trabajo en que aplicamos, de forma pionera en Paleontología Humana, los métodos del análisis fractal al estudio comparativo de las suturas preservadas en el fragmento craneal de Homo sp. de Venta Micena (Orce, Granada) se pueden clasificar, según nuestro criterio, en dos grupos principales: por una parte, las que parecen venir motivados por la ausencia de determinadas aclaraciones y explicitaciones que en su momento no consideramos necesario realizar y, por otra, aquellos derivados de ciertas malinterpretaciones y errores conceptuales cometidos, a nuestro juicio, por el propio Martin Escorza. A continuación, pasamos a argumentar nuestra contrarréplica, centrada en torno a los diferentes bloques temáiticos en que se distribuyen las críticas.
Primeras evidencias de briozoos perforantes (Ctenostomata) en braquiópodos ordovícicos de los Montes de Toledo (Zona Centroibérica meridional, España).
Authors: Mayoral Alfaro Eduardo , Gutiérrez Marco Juan Carlos , Martinell Callicó Jordi
Published: September 2022

Se describe un nuevo sistema de perforación (Pinaceocladichnus perplexus isp. nov.), registrado en conchas de braquiópodos articulados (órtidos) del Ordovícico Medio de los Montes de Toledo (Centro de España). Los icnofósiles se conservan como moldes naturales tras la disolución de las conchas que constituyen su sustrato, permitiendo estudios detallados al MEB. Este tipo de estructuras es claramente comparable con perforaciones de briozoos ctenostomados (Stolonifera actuales o fósiles), por lo que P. perplexus isp. nov. representa la evidencia más antigua de actividad bioerosiva imputable a este grupo. La infestación de las conchas por los briozoos ocurrió probablemente en vida de los braquiópodos, a diferencia de lo que ocurre en otras formas ibéricas de Pinaceocladichnus. La colonización afectó preferentemente al área marginal (sector anterior o lateral) de las valvas dorsales, perforando siempre niveles someros de las mismas. Además de la especificidad taxonómica de estos icnofósiles, su registro está limitado aparentemente a sectores relativamente profundos de la plataforma centroibérica durante la época Oretana inferior.
Devonian udoteacean green algae from the Cantabrian Mountains (Santa Lucía Formation), NW-Spain.
Authors: Herrmann Regina , Hubmann Bernhad
Published: September 2022

The erect Udoteacean green algae Pseudopalaeoporella lummatonensis (Elliott, 1961) and "Litanaia" graecensis Hubmann, 1990 are described from the Santa Lucía Formation (Lower to Middle Devonian; Upper Emsian to Lower Eifelian) at Geras de Gordón (NW-Spain, Cantabrian Mountains). Investigations of the depositional environment of the sections containing udoteacean thalli indicate a position in a protected subtidal area on a gently inclined ramp. Floristic and biogeographical relations are discussed.
Seminario. Presencia de una asociación de cráneos de grandes mamíferos en Venta Micena.
Authors: Martinez Navarro Bienvenido , Gibert Josep , Palmqvist Paul , Santamaria Jose Luis
Published: September 2022

En 1984 se descubrió en el Corte-III de Venta Micena una espectacular acumulación de cráneos y mandíbulas de grandes mamíferos (ver figura adjunta). La integran un cráneo de tigre de dientes de sable (1) (Homotherium latidens), uno de elefante infantil (2) (Mammuthus meridionalis), uno de rinoceronte (3) (Stephanorhinus etruscus), un cráneo (4) un paladar (5) y una hemi­mandíbula (6) de caballo (Equus cf. numidicus; Vera Eisenmann, com. pers.) y una hemimandibula de bufalo de agua (7) (Bubalus sp.). Actualmente se expone en una sala del Museo de Prehistoria y Paleontología de Orce. No se ha descrito una asociación de este tipo en otros yacimientos estratiformes del Plio-Pleistoceno, por lo que su singularidad resulta evidente.

Piedrabuena y las Higueruelas: aportación a la cronoestratigrafía del Villafranquiense del Campo de Calatrava (Ciudad Real).
Authors: Mazo Ana V.
Published: September 2022

Se comparan las faunas pliocenas de Piedrabuena y las Higueruelas (sector del Campo de Calatrava) y en función de su micro y macromamiferos, se determinan sus posiciones cronoestratigráficas respectivas utilizando como referencia la zonación de Mein (1975, 1990). Piedrabuena con Hyaena sp., Stephanorhinus cf. etruscus, Sus minor, cervidae indet. cf. Cervus perrieri o Arvernoceros ardei y un hippotraginae que hasta ahora sólo se había encontrado en el Rusciense, se sitúa en los niveles más bajos del Villafranquiense o en la transición Rusciniense/Villafranquiense. Las Higueruelas, con Stepahonomy cf. laynensis, Castillonomy crusafonti crusafonti, hipparion rocinantis, Stepahonorhinus etruscus y Arvernoceros ardei, es más reciente, con una edad aproximada de 3 ± 0.1 Ma. Se establecen correlaciones bioestratigráficas con otros yacimientos europeos y se propone un marco paleoecológico.
Controles paleoambientales sobre la distribución de las paleoicnocenosis en el estuario plioceno del Baix Llobregat (Barcelona, Catalunya).
Authors: De Gibert Jordi Maria , Martinell Jordi
Published: September 2022

En el Plioceno del Baix Llobregat se han podido diferenciar ocho icnoasociaciones. A pesar de su distribución muy local ha sido posible establecer que tres son los parámetros paleoecológicos principales que las controlan: substrato, energía hidrodinámica y salinidad. El estudio de la icnofósiles ha permitido obtener información de tipo paleoambiental acerca de estos tres parámetros. En función de la salinidad se ha podido establecer una zonación de la cuenca en tres sectores: salobre, intermedio y claramente marino. Se ha puesto de manifiesto el carácter regresivo de la serie pliocena y la progresiva profundización de la cuenca hacia el Sur. También se ha reconocido un fuerte control del substrato sobre la vida endobentónica condicionado por la mayor o menor presencia de partículas orgánicas en el sedimento.
Las zonas de graptolitos de la Formación Gualcamayo (Arenigiano tardío-Llanvirniano temprano) en el norte de la Precordillera (provincias de la Rioja y San Juan), Argentina.
Authors: Ortega Gladys , Toro Blanca , Brussa Edsel
Published: September 2022

Se efectuó el análisis de la graptofauna proveniente de las quebradas de Los Sapitos y Potrerillos, ubicadas al suroeste de la localidad de Guandacol, en el límite entre las provincias de La Rioja y San Juan, Precordillera Argentina. Los fósiles están contenidos en una secuencia dominantemente elástica, de edad arenigiana tardía a llanvirniana temprana, correspondiente a la Formación Gualcamayo. Estas rocas son portadoras de abundantes graptolitos y contienen restos de artrópodos (trilobites y filocáridos) y braquiópodos. En base al estudio realizado se definieron las Zonas de Isograptus victoriae maximus y Oncograptus, citadas por primera vez para Argentina, y la Zona de Paraglossograptus tentaculatus. Se discuten las asociaciones diagnósticas de estas biozonas, la distribución de los taxones que las integran, su edad, biofacies y aspectos paleobiogeográficos. Asimismo, se comparan estos aíloramientos con otros del Ordovícico Inferior de la Precordillera y se propone una correlación intercontinental.
Paleozoic paleogeography and biogeography.
Authors: Boucot A. J.
Published: September 2022

An attempt is now being made to reconcile the data of Paleozoic climatically sensitive sediments, such as evaporites, coals, and bauxites, with the contemporary biogeographic data. This attempt results in sorne new paleogeographic reconstructions that are very different from those based on the data of remanent magnetism, and are more consistent with the available biogeographic data.
Cronoestratigrafía de los arrecifes Neógenos del Corredor del Almanzora (Cordillera Bética, España).
Authors: Guerra Merchán Antonio , Serrano Lozano Francisco
Published: September 2022

El corredor del Almanzora es una estrecha depresión neógena que formó parte del sistema de canales de comunicación entre los ambientes marinos atlánticos y mediterráneos durante el Mioceno Superior. Su relleno rniocénico es esencialmente siliciclástico y se estructura en cuatro unidades tectosedementarias (UTS). Durante el depósito de las UTS II y III, hubo crecimiento de arrecifes en ambientes costeros y muy someros. En general, se trata de edificios pequeños y aislados, construidos mayoritariamente por corales (sobre todo Porites y Tarbellastraea) y algas rojas.
Las bioconstrucciones pertenecientes a la UTS-II son de tipo parche (patch-reef) y están asociados exclusivamente a abanicos deltaicos que se desarrollaron en ambos márgenes de la cuenca. Las margas de cuenca de esta unidad contienen asociaciones de forarniníferos planctónicos asignables a la parte alta del Tortoniense inferior y a la parte baja del Tortoniense superior, subdividiendo el Tortoniense mediante el BPA de Neogloboquadrina humerosa (Takayanagi y Saito). Dentro de la UTS-III se pueden distinguir dos grupos de arrecifes. Uno está formado por arrecifes costeros, instalados sobre un paleorrelieve originado tras la etapa tectónica intratortoniense que cierra la UTS-11. El otro grupo corresponde a parches arrecifales (patch-reefs), generalmente de menores dimensiones, que aparecen asociados a abanicos deltaicos desarrollados en los bordes de la cuenca. Los sedimentos contemporáneos más profundos contienen asociaciones de forarniníferos planctónicos de la parte baja y media del Tortoniense superior.
