TÉCNICAS DE SENSORIAMENTO REMOTO APLICADOS NA ANÁLISE DE SECA EM BACIAS HIDROGRÁFICAS: ESTUDO DE CASO NA SUB-BACIA DO RIBEIRÃO SERRA AZUL - MG
Authors: Dutra Débora Joana , Elmiro Marcos Antônio Timbó
Published: February 2024

As recorrentes pressões antrópicas no ambiente têm ocasionado diversas alterações nos ciclos naturais, dentre eles o ciclo hidrológico. A principal consequência das mudanças do ciclo hidrológico está associada ao agravamento da seca e à presença de eventos de escassez hídrica. Nesse aspecto, o objetivo desse trabalho é verificar a eficácia de dados do sensor MODIS para análise de seca meteorológica e hidrológica na região da sub-bacia do ribeirão Serra Azul (MG) por meio de aplicação do índice de condição de vegetação (ICV). Para isso, realizou-se o cálculo do ICV e análises estatísticas com dados meteorológicos, hidrológicos e relatórios climatológicos entre os anos de 2013-2018 com o intuito de identificar a abrangência de seca na sub-bacia. Os resultados permitiram identificar que a presença de eventos externos e aspectos regionais contribuiu para o agravamento da seca. Além disso, verificou-se que a umidade do solo pode ter influenciado o armazenamento de água na região de estudo. Através dos resultados obtidos, verificou-se que o ICV possui capacidade significante para identificar eventos de seca na região de estudo, confirmando-se por estatísticas nas regressões e correlações das variáveis.

POR UMA ARQUEOLOGIA GEOGRÁFICA OU GEOGRAFIA ARQUEOLÓGICA DAS TERRAS ALTAS MINEIRAS – REFLEXÕES SOBRE O USO DO CONCEITO CULTURALISTA DE PAISAGEM NO ALTO VALE DO ARAÇUAÍ, MINAS GERAIS
Authors: Fagundes Marcelo , Greco Wellington Santos , Poma Juan Carlos Izaguirre , Campos Paulo Andrade , Fonseca Thamara Ferreira
Published: February 2024

Este artigo tem como objetivo realizar uma reflexão e apresentar uma síntese acerca de como o conceito geográfico culturalista de paisagem tem sido empregado nas pesquisas arqueológicas que estão sendo levadas a cabo em Serra Negra, face nordeste da Serra do Espinhaço Meridional, Alto Vale do Araçuaí, Minas Gerais. Para tanto, o conceito de paisagem tem sido utilizado como meio para relacionar as pesquisas, sendo considerado fundamental para a compreensão das dinâmicas, organização espaço-tempo e tecnológica, e trajetórias históricas (vivências) de grupos que ocuparam a região por milênios. Neste caso, a paisagem é parte da vida humana, em que ela só existe por meio de nosso julgamento, apreciação, compreensão, etc., ou seja, é uma construção humana, não existindo apenas na materialidade, se constituindo em camadas de práticas socioculturais, narrativas e existências (ancestrais e atuais). As ocupações se estabelecem, se apropriam e reinterpretam as anteriores e, portanto, contemporâneas. Entendemos que paisagem e humanos são vetores de inter-relações, negociações e reciprocidades. Não existe paisagem sem humanos, não existe humanidade sem paisagem.

Groundwater is a valuable resource for meeting the daily needs of humans, which continues to increase along with population growth. Therefore, it is essential to maintain groundwater properly. Groundwater management can be carried out comprehensively in groundwater basins, including determining groundwater recharge areas. This study aims to determine the location of groundwater recharge to conserve groundwater in Denpasar City to create groundwater sustainability. The geospatial analysis uses a weighting and scoring approach (Overlay Weighted Sum) to determine the groundwater recharge area. Retrieval data in the field by observing geological conditions and measuring the depth of the phreatic surface in Denpasar City. The determination of recharge and discharge areas was analyzed using the geospatial method using the ArcGIS 10.8 application using Interpolation Inverse Distance Weighted (IDW). The five parameters used in this scoring assessment are lithology, rainfall, soil cover type, slope, and phreatic surface depth. The highest score obtained from the weighting of the scoring is 46, while the lowest score is 36. The recharge area is found in the weighted value of 41-46, which is in the northern region of Denpasar City. The discharge area is located at a weight value of 36-41 in the southern area of Denpasar City.

Published: February 2024

The open dumping system implemented by the Batu Layang landfill can produce leachate, contaminating groundwater around the landfill. Groundwater contaminated with leachate, if used by the community, can cause health problems. Therefore, management efforts were needed, such as subsurface leachate modeling. This study aims to model the distribution of subsurface leachate in 2 dimensions. The modeling of leachate distribution below the soil surface used the Wenner configuration geoelectric method. The number of geoelectric measurement paths was two paths. The length of each track was 195 m, with a distance of 5 m between the electrodes. Data obtained from resistivity values were analyzed using the Res2Dinv application. The calculation of leachate discharge used the water balance method. Based on the inversion results using the Res2Dinv software, the resistivity value of leachate-contaminated soil in line 1 was 1.19-9.43 Ωm, and track 2 was 0.5-10.2 Ωm. The leachate resistivity value was <10 Ωm because the leachate contains inorganic minerals (metals), so the resistivity value was low. Land contaminated with leachate was estimated to be spread as far as 195 m. The most profound leachate depth was estimated at 39.4 m. Batu Layang Landfill leachate discharge in Zone E averages 4 m3/day.

Published: February 2024

Bali's administrative center, Renon Village, faces an increased risk of flooding due to land cover change. Conservation is needed to reduce this risk by improving water infiltration capacity. Infiltration wells are a solution to increase infiltration capacity. The Tri Hita Karana concept approach, especially Palemahan, in Balinese culture is adopted to implement infiltration well conservation with the support of GIS technology and by flood regulations and infiltration wells. The analysis showed that with a land area of 100 m2, the dimensions of the infiltration well were obtained in diameter of 1 m, and a depth of 2 m with a total of 2 pieces could absorb 2.46 m3 of rainwater. The application of infiltration wells in the study area can reduce the discharge and volume of flood peaks of 2 years, 5 years, 10 years, 25 years, 50 years, 100 years, and 200-year flood peaks, effectively reducing from 8.61% to 31.24%. This research supports the planning of sustainable drainage with a Low Impact Development approach. In addition, the construction of infiltration wells also contributes to preserving water conservation and applying green buildings that are environmentally friendly and energy efficient.

Propidium iodide (PI) and YO-PRO-1 (YPI) dyes are routinely used to determine sperm viability in many livestock species. It is commonly accepted that these dyes penetrate only sperm cells with damaged plasma membranes. Recently, however, the mechanism of dye uptake unrelated to damaged plasma membranes, but instead related to pannexin channels in dog and stallion sperm cells was demonstrated. This pilot study aimed to evaluate the role of pannexins in the uptake of PI and YPI dyes on Wallachian frozen-thawed ram spermatozoa by flow cytometry using probenecid, a specific inhibitor of pannexin channels. Additionally, the expression of pannexins in Wallachian sperm was evaluated directly (by qRT-PCR). The results demonstrate the active role of pannexin channels in the uptake of PI and YPI dyes on frozen-thawed Wallachian ram sperm. In conclusion, when using the PI or YPI exclusion assay to determine Wallachian frozen-thawed ram sperm viability, the danger of overestimating the number of spermatozoa with the damaged plasma membrane must be considered. The observed breed-specific, and more importantly, individual differences in gene expression as well as in dye uptake indicate the need for further studies.

Published: February 2024

The main component of drug production and formulation, with minimal to no adverse effects, is plant-based medicine. Citrus macroptera is an endangered species of North-Eastern India and has a diverse array of pharmaceutical applications owing to the presence of several bioactive compounds. The study aimed to evaluate the presence of bioactive metabolites, antioxidants, and cytotoxic mechanisms of the in vitro and ex-vitro leaf extracts of C.macroptera. Gas chromatography–mass spectrometry (GC-MS) profiling was performed using the ethanolic leaf extracts. Methanolic and aqueous extracts were profiled using High-performance thin-layer chromatography (HPTLC). Moreover, the cytotoxicity of the methanolic leaf extracts was assessed using the 3-[4,5-dimethylthiazole-2-yl]-2,5-diphenyltetrazolium bromide (MTT) test against SH-SY5Y, human neuroblastoma cell lines. GC-MS analysis revealed the existence of numerous pharmacologically significant components such as esters, hydrocarbons, fatty alcohols, and ester compounds. The presence of flavonoids and stigmasterol was exhibited by the HPTLC profile. The in-situ HPTLC analysis revealed white fluorescence after derivatization under white light that explicitly confirms the antioxidant potential of the extracts and can serve as a lead source of natural antioxidants. The cytotoxic efficacy of the extracts was observed in a concentration-dependent manner. However, the in vitro leaf extract displayed better suppressive effects against the SH-SY5Y cells with a 24-h IC50 of 167.71?g/mL compared to the ex-vitro leaf extract. Further, a comprehensive study is necessary to identify the cytotoxic compounds and their mode of action. The outcome of our investigation provides empirical evidence that phytoconstituents present in the leaf extracts of C. macroptera can be used as an effective pharmaceutical agent to combat several diseases.

Authors: Kim Dongho , Park Eun-Jae , Seo Boyoon
Published: February 2024

In this article, we propose an adaptive mesh-refining based on the multi-level algorithm and derive a unified a posteriori error estimate for a class of nonlinear problems.
We have shown that the multi-level algorithm on adaptive meshes retains quadratic convergence of Newton’s method across different mesh levels, which is numerically validated.
Our framework facilitates to use the general theory established for a linear problem associated with given nonlinear equations.
In particular, existing a posteriori error estimates for the linear problem can be utilized to find reliable error estimators for the given nonlinear problem.
As applications of our theory, we consider the pseudostress-velocity formulation of Navier–Stokes equations and the standard Galerkin formulation of semilinear elliptic equations.
Reliable and efficient a posteriori error estimators for both approximations are derived.
Finally, several numerical examples are presented to test the performance of the algorithm and validity of the theory developed.

Published: February 2024

It takes 3–5 years for the stable rust layer to form when the bridge weathering steel is used in the industrial atmosphere, and the loose rust layer appearing in the early stage will pollute the atmospheric environment. Therefore, a method for the rapid formation of stable rust layer is developed in this paper, and the influence of rust layer stabilizing treatment on corrosion behavior of bridge weathering steel Q345qNH in simulated industrial atmospheric medium is studied. The results showed that in simulated industrial atmospheric medium, the stabilizing treatment shortened the formation time of stable rust layer and significantly reduced the corrosion rate, which is 47.9 % lower than that of bare steel after 480 h of corrosion. During the whole corrosion process, the Iα-FeOOH/Iγ-FeOOH peak intensity ratio of the stabilizing treatment steel was always higher than that of the bare steel, and was 1.26 times that of the bare steel after 480 h corrosion. After the stabilizing treatment, the self-corrosion potential of the rust layer increases, the self-corrosion current density decreases, and the resistance of the rust layer after 480 h corrosion was 1.57 times that of the bare steel sample, and the protection of the rust layer was significantly improved.

Published: February 2024

In recent years, metasurface, as a representative of micro- and nano-optics, have demonstrated a powerful ability to manipulate light, which can modulate a variety of physical parameters, such as wavelength, phase, and amplitude, to achieve various functions and substantially improve the performance of conventional optical components and systems. Artificial Intelligence (AI) is an emerging strong and effective computational tool that has been rapidly integrated into the study of physical sciences over the decades and has played an important role in the study of metasurface. This review starts with a brief introduction to the basics and then describes cases where AI and metasurface research have converged: from AI-assisted design of metasurface elements up to advanced optical systems based on metasurface. We demonstrate the advanced computational power of AI, as well as its ability to extract and analyze a wide range of optical information, and analyze the limitations of the available research resources. Finally conclude by presenting the challenges posed by the convergence of disciplines.
Fourier imaging for nanophotonics
Authors: Cueff Sébastien , Berguiga Lotfi , Nguyen Hai Son
Published: February 2024

Standard optical characterization and spectroscopy techniques rely on the measurement of specular reflection, transmission, or emission at normal incidence. Although the usefulness of these methods is without question, they do not provide information on the angular dependence of the scattered light and, therefore, miss crucial insights on the physical processes governing light emission and scattering. In this Review, we explain the basics of Fourier imaging and show how it can be used to measure the angular distribution of scattered light in single-shot measurements. We then give a comprehensive panorama on recent research exploiting this technique to analyze nanostructures and detail how it unlocks fundamental understandings on the underlying physics of nanophotonic structures. We finally describe how simple additions to a Fourier imaging setup enable measuring not only the radiation pattern of an object but also the energy, polarization, and phase toward resolving all aspects of light in real time.
Nietzsches Hermeneutik der Einsamkeit. Transformationen im Labyrinth der Wahrheit
Authors: Schlenker Christian
Published: February 2024

Nietzsche’s Hermeneutics of Loneliness. Transformations in the Labyrinth of Truth. This article delves into Nietzsche’s intricate exploration of solitude and its multifaceted manifestations in Thus Spoke Zarathustra. By distinguishing between various instances of solitude experienced by Zarathustra, including his initial journey, recurring returns, and dreamt solitude, the study unveils the creative nature of his solitude. Unlike the ascetic pursuit of transcendent truth, Nietzsche reevaluates solitude, highlighting its eternal ambiguity and challenging the notion of a fixed self or ultimate truth attainable through isolation. The hermeneutics of solitude in Nietzsche’s philosophy illustrates how perspectives and self-interpretation intertwine, shaping one’s experience within the labyrinth of truth. The article further examines the intimate relationship between solitude and perspective, emphasizing that genuine solitude emerges only through communication. Through a comprehensive analysis of shame as a mirror-motif of solitude, this study underscores the inherent connection among these concepts, rooted in the dynamics of human communication and self-revelation. It concludes that one’s position toward truth is fundamentally linked to one’s role as an interpreter and something interpreted, offering insights into the complexities of human existence and self-understanding.

Published: February 2024

The results published in the literature on the maturity of BPM in organisations, taking into account both the degree of implementation of process management and process orientation, indicate that the majority of the organisations surveyed in Poland exhibit a low level of maturity. Despite the increasing number of studies attempting to assess organisational process maturity, it is important to highlight the discourse in foreign subject literature regarding a critical perspective on maturity models. This primarily concerns the utilitarian aspect, which is identified as the limited practical value of applying maturity models. The main objective of this article is to evaluate the current state of knowledge on business process management (BPM) maturity in Polish and foreign subject literature, and to outline directions for further research on process maturity, with a special focus on new requirements and opportunities arising from Industry 4.0 and the emerging Industry 5.0. In order to achieve this objective, research methods such as bibliometric analysis and systematic literature review were applied. The outcome of this study includes the identification of limitations related to both the methods and models for assessing business process management maturity, as well as the presentation of recommendations for future research directions on process maturity.
Early Visual Cortices Reveal Interrelated Item and Category Representations in Aging
Authors: Pauley Claire , Karlsson Anna , Sander Myriam C.
Published: February 2024

Neural dedifferentiation, the finding that neural representations tend to be less distinct in older adults compared with younger adults, has been associated with age-related declines in memory performance. Most studies assessing the relation between memory and neural dedifferentiation have evaluated how age impacts the distinctiveness of neural representations for different visual categories (e.g., scenes and objects). However, how age impacts the quality of neural representations at the level of individual items is still an open question. Here, we present data from an age-comparative fMRI study that aimed to understand how the distinctiveness of neural representations for individual stimuli differs between younger and older adults and relates to memory outcomes. Pattern similarity searchlight analyses yielded indicators of neural dedifferentiation at the level of individual items as well as at the category level in posterior occipital cortices. We asked whether age differences in neural distinctiveness at each representational level were associated with inter- and/or intraindividual variability in memory performance. While age-related dedifferentiation at both the item and category level related to between-person differences in memory, neural distinctiveness at the category level also tracked within-person variability in memory performance. Concurrently, neural distinctiveness at the item level was strongly associated with neural distinctiveness at the category level both within and across participants, elucidating a potential representational mechanism linking item- and category-level distinctiveness. In sum, we provide evidence that age-related neural dedifferentiation co-exists across multiple representational levels and is related to memory performance.

Supercritical water gasification of oily sludge and its life cycle assessment
Authors: Qiu Yuxin , Liu Yunyun , Fang Chong , Ju Miaomiao , Xia Rundong , Wang Yujing
Published: February 2024

A supercritical water gasification strategy was employed to investigate the effects of different conditions on hydrogen-rich gas production from oily sludge, based on the Aspen Plus platform. Meanwhile, the entire process was assessed with a life cycle assessment (LCA) method. The results indicated that the gas yield was decreased by increasing the sludge concentration. The yield of hydrogen-rich gas (H2 and CH4) was improved with increasing temperature. Higher temperatures were more favorable to gas production. Excessive addition of oxidants could reduce the CH4 yield, thereby lowering the energy efficiency of the process. The LCA analysis found that, in comparison to the stages of raw material transportation, heat recovery, and wastewater treatment, the effect of more CO2 produced in cooling and separation stage on global warming potential (GWP) was more obvious. The corresponding process can be improved to mitigate the environmental effect of the whole gasification.
Sensory Qualities as Signs? Meyer Schapiro as a Pioneer of the Semiotics of ‘Visual Form’
Authors: Andersson Fred
Published: February 2024

The concept and nature of Form in linguistic as well as visual signs has been debated among several semioticians and art historians. Some notable analytical attempts have been put forward by Saussure, Hjelmslev, Vygotsky, and, regarding visual signs in particular, by Meyer Schapiro, Floch, Greimas, and the Groupe µ, among others. Greimas and Floch proposed a distinction between two levels of semiotic Form in visual representation, each being constitutive of a separate system of semiotic articulation: figurative language and plastic language. With arguments drawn from behavioural science, the interdisciplinary Groupe µ presented a different version of the same distinction as one between iconic and plastic signs.
In this paper, I shall give a short outline of these and some further proposals, especially Meyer Schapiro’s view on the formal structure of pictures and visual signs, and his analysis of visual signifiers as ‘vehicles’ of spatial meaning. Schapiro’s account of the ‘image-sign’ will be presented as coloured by his socio-historical perspective and the empirical pragmatism of Peirce. Regarding the relationship between ‘iconic’ and ‘plastic’ meaning, Schapiro’s studies of Romanesque sculpture and non-figurative painting anticipate some observations later made by the Groupe µ. However, rather than attempting to defend any specific account of the nature of visual or plastic Form, a pluralistic position will be proposed here.

Plasma B-endorphin and cortisol profiles around periparturient period in Friesian Cattle suffering from reproductive disorders in Egypt
Authors: Elhady HA Abed , Malky OM El , Gezery IS Al , RS Mourad
Published: February 2024

The present study aimed to determine plasma β-endorphin and cortisol concentrations in cattle with reproductive disorders (dystocia and retained placenta) and weakness body condition score during periparturient period. Stress may cause an overproduction of beta-endorphins and free radicals. Twenty multiparous Friesian cows weighing 400–650 kg aged 6-10 years and between (3-8) parities at late pregnancy period was used for two months before parturition. From ten days before the expected birth date the birth canal of each animal was monitored by rectal and vaginal palpations, and the body temperature was checked daily to predict the probable time of parturition. Animals were divided into four groups according to parturition disorders’ five animals in each one. First group delivered spontaneously at term with no obstetrical assistance(A), second group delivery was at term but was accompanied by dystocia(B), third group delivery was at term but was accompanied by retained placenta(C), and fourth group delivery was at term but animals showed weakness body condition score (D). Results illustrated that Plasma β-endorphin level in Friesian cattle during pregnancy state increased gradually through gestation period. It reaches its highest level during the third trimester due to stressful state. Also, it reaches its peak at zero time of parturition by appearing its analgesic action. Meanwhile, it decreases gradually towards re-establishment of ovarian cycle. Generally, cows suffering reproductive disorders had a clear impact on blood plasma β-endorphin concentration around parturition process.

Canine Parvoviral Enteritis [CPE] is acute highly contagious and often fatal viral enteritis of domesticated and wild canidae [dogs, foxes coyotes]. Caused by three variants of a virulent single stranded naked DNA virus belonging to the family Parvoviridae designated Canine Parvovirus Type 2 [CPV-2]. This disease is transmitted to susceptible animals directly via inhalation of viral particles or by ingestion of food contaminated by infected feces excreted by sick puppy or indirectly through contact with contaminated formites by infected feces excreted by clinically sick animal. The virus has high tropism for rapidly dividing cells, it is similar genetically to Feline Panleucopenia Virus [FPV]. Infact it only differ from FPV by two amino acids in it viral capsids. It was first reported in 1978 in North America and it became pandemic within six months of it first official report has two major clinical manifestation

The purpose of this study is to compare clinical results in horses with a reinjury of the superficial digital flexor tendon (SDF) treated with desmotomy of the accessory ligament of SDF or with “counterirritation” through a blister ointment. Horses have been divided into two groups: Group 1-horses treated with surgery; Group 2 horses treated with the application of a blister ointment. The results have shown in Group 1 one horses had a recurrent injury to the SDF after the second competition, instead in Group 2 one horse had a recurrent injury to the SDF after the third competition, one after the first and one after the second. In the present study no statistically significant differences (P=0,058) were detected between the two groups in terms of performance and reinjury incidence for about five competitions.

A Persian cat was presented with a history of hair fall, intense itching, mostly on the spine of the body, legs and ear pinnae. The cat was having decreased appetite and debilitated body condition and poor skin coat. Clinical examination revealed poor skin coat, self-inflicted lesions on the body due to intense itching, however, physiological parameters were within normal range. The cat was diagnosed as mange on the basis of severe pruritus, crusts, and alopecia on the ears, spine, legs and belly and was confirmed by skin scraping. The cat was treated with Ivermectin (200 mcg/kg, SC), weakly for two months and also hydroxyzine HCl @ 2 mg/ Kg body weight, BID, PO, for five days, and antibiotic cephalexin @ 30 mg/ Kg body weight, BID, PO, for five days. The cat showed gradual response to the therapy as evidenced by decrease in the hair fall, improvement in the itching and hair regrowth after two weeks on parts of alopecia. The cat recovered successfully and it took three months for complete regrowth of the hair coat.
The CUSUM model, a security tool
Authors: Ricardo Navarro-Vargas Jose
Published: February 2024

The Cusum method allows the student is evaluated personalized way. It requires software where alpha and beta errors and acceptable failure rate (h0) or unacceptable (h1) are set. When the participant is within the limits of decision h0 and h1 is within the learning curve and just across the decision limit h0, it can be considered that it has acquired efficiency in performing this procedure (competition).
Solar dynamo modes of oscillations and the long- term prediction of solar activity
Authors: Duhau Silvia , de Jager Cornelis
Published: February 2024

We verify that the values and dates of occurrence of sunspot maxima during Schwabe sunspot cycles ##19 to 24 as predicted by Derek Justin Schove in 1955 coincide with the actually observed ones with a high degree of accuracy. A question arises from this result: why is such a deterministic behavior apparent in a system, like the solar dynamo, that is in principle stochastic. We find that solar activity related data may be well represented by the addition of a constant level and eight modes of oscillation. The repetitive behavior and the relationships that appears to exist between these modes, opens the possibility for a long-term prediction of solar activity. In that line, we forecast the Gleissberg cycle for the forthcoming two centuries and data on sunspot maxima for the next century. Thus, we predict the values and dates of occurrence of sunspot maxima ##25 to 35 and find that the new Episode of solar activity that started during polar cycle #24, as a follow-up of the 20th century Grand Maximum, is of the Regular type and, as the ongoing Hallstatt oscillation will pass through zero from negative to positive around the year 2036, it will last for the remainder of the present millennium. We also find that modes of oscillations are mutually related through a forced non-linear oscillator with a persistent asymmetry. A brief discussion of the origin of this behavior on the excitation of solar dynamo motions by solar-planetary forces is presented.

Research in Pediatric Hospital Medicine is growing and expanding rapidly, and with this comes the need to expand single-site research projects into multisite research studies within practice-based research networks. This expansion is crucial to ensure generalizable findings in diverse populations; however, expanding Pediatric Hospital Medicine research projects from single to multisite can be daunting. We provide an overview of major logistical steps and challenges in project management, regulatory approvals, data use agreements, training, communication, and financial management that are germane to hospitalist researchers launching their first multisite project by sharing processes and lessons learned from running multisite research projects in the Pediatric Research in Inpatient Settings Network within the Eliminating Monitor Overuse study portfolio. This description is relevant to hospitalist researchers transitioning from single-site to multisite research or those considering serving as site lead for a multisite project.
Flora and similarities of a rocky outcrop in the Caatinga, eastern region of South America

Published: February 2024

Rocky environments show great habitat heterogeneity and very specific microclimatic characteristics that select for appropriately adapted floristic assemblages. A floristic survey was carried out on a rock outcrop in the driest portion of the Cariri Environmental Protection Area (APA) in Paraíba State, northeastern Brazil, to determine its similarity to other Caatinga sites. We recorded 128 species distributed among 103 genera and 52 families. Fabaceae, Convolvulaceae, Malvaceae, Euphorbiaceae, Asteraceae, Cactaceae, Bromeliaceae, Rubiaceae, and Poaceae were the most representative families in terms of numbers of species, with a high representation of herbaceous and shrub components and a predominance of typically Neotropical species, in addition to endemic taxa. Pectis linifolia L. (Asteraceae) is recorded here for the first time in the Paraíba state, Brazil. Similarity analysis evidenced that the study area, located in an extremely dry Caatinga zone, evidenced floristic relationships with other rocky outcrops in more humid areas, suggesting that habitat type is important for selecting specific groups, following the theory of refuges.

Bioactive cements based on tricalcium silicate have been introducedto the market for use in dentistry, with a variety of clinical applications. These cements are in contact with vital tissues such as dental pulp or periodontium in cases of unintentional extrusion; thus, it is important to know the genotoxicity and cytoxicity of these materials. The objective of this study was to evaluate the cytotoxicity and genotoxicity of bioactive sealers, Bio-C® Sealer and MTA Repair HP®, in human fibroblasts. Discs of bioactive sealers Bio-C® Sealer, and MTA Repair HP®, were prepared and set for 24h under sterile conditions. The discs were placed in culture medium at 2.5mg/mL inside a SRT6D roller mixer (Stuart, UK) at 60rpm for 24h. The eluates obtained were incubated for 24h with previously activated and cultured ATCC cell line fibroblasts at 80% confluence. The cytotoxicity was evaluated by Alamar Blue® and LIVE/DEAD assays, as well as the analysis of the Tunel and Mitotracker assays to evaluate genotoxicity using the confocal laser-scanning microscope. In the Alamar Blue® assay, the Bio-C® Sealer presented a cell proliferation of 87%, while the MTA Repair HP® Sealer was 72%. A statistically significant difference was found between the MTA Repair HP® Sealant and the negative control (p=<0.001). Regarding the genotoxicity tests, in the Tunel assay, both materials stain the nucleus of the fibroblast cells exposed to the eluates, while in the Mitotracker assay, the MTA Repair HP® Sealer showed greater mitochondrial function than the Bio-C® Sealer. Calcium silicate-based sealers, Bio-C® Sealer and MTA Repair HP®, are not cytotoxic and have low genotoxicity.
