DYNAMIC THRESHOLDS OF GEOMETRIC CONSISTENCY INDEX ASSOCIATED WITH PAIRWISE COMPARISON MATRIX
Authors: Lin Changsheng , Kou Gang , Peng Yi , Hefni Mohammed A.
Published: July 2022

Pairwise comparison matrix (PCM) has been widely employed in the multi-criteria decision-making (MCDM) problems to rank the criteria and alternatives according to the considered criteria in Analytic Hierarchy Process (AHP). The PCM should have the acceptable consistency before deriving a priority vector from it. Approximate thresholds of geometric consistency index (GCI) and consistency ratio (CR) have been proposed to test whether the PCM has the acceptable consistency. However, approximate thresholds of GCI and CR always suffer from some criticisms and disagreements in existing literature. In this paper, we try to induce dynamic thresholds of GCI by combining hypothesis testing and random index (RI), which vary with the order of the PCM, significance level and assessment level of decision maker. The induced dynamic thresholds of GCI may explain different (or conflicting) results obtained by approximate thresholds of GCI and CR and avoid the unnecessary revisions of some judgments of the PCM for the desired consistency. Finally, several numerical examples and real-world decision-making problems are examined and compared with existing decision-making methods to illustrate the performance of dynamic thresholds of GCI.
Fermi-LAT Detection of a GeV Afterglow from a Compact Stellar Merger

Published: July 2022

It is usually thought that long-duration gamma-ray bursts (GRBs) are associated with massive star core collapse, whereas short-duration GRBs are associated with mergers of compact stellar binaries. The discovery of a kilonova associated with a nearby (350 Mpc) long-duration GRB—GRB 211211A, however, indicates that the progenitor of this long-duration GRB is a compact object merger. Here we report the Fermi-LAT detection of gamma-ray (>100 MeV) afterglow emission from GRB 211211A, which lasts ∼20,000 s after the burst, the longest event for conventional short-duration GRBs ever detected. We suggest that this gamma-ray emission results from afterglow synchrotron emission. The soft spectrum of GeV emission may arise from a limited maximum synchrotron energy of only a few hundreds of MeV at ∼20,000 s. The usually long duration of the GeV emission could be due to the proximity of this GRB and the long deceleration time of the GRB jet that is expanding in a low-density circumburst medium, consistent with the compact stellar merger scenario.

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) 19-beam tracking observational mode, high-sensitivity and high-velocity-resolution H i spectral lines have been observed toward the high-mass star-forming region G176.51+00.20. This is a pilot study searching for H i narrow-line self-absorption (HINSA) toward high-mass star-forming regions where bipolar molecular outflows have been detected. This work is confined to the central seven beams of FAST. Two HINSA components are detected in all seven beams, which correspond to a strong CO emission region (SCER; with a velocity of ∼−18 km s−1) and a weak CO emission region (WCER; with a velocity of ∼−3 km s−1). The SCER detected in Beam 3 is probably more suitably classified as a WCER. In the SCER, the HINSA is probably associated with the molecular material traced by the CO. The fractional abundance of HINSA ranges from ∼1.1 × 10−3 to ∼2.6 × 10−2. Moreover, the abundance of HINSA in Beam 1 is lower than that in the surrounding beams (i.e., Beams 2 and 4–7). This possible ring could be caused by the ionization of H i or the relatively rapid conversion from H i to H2 in the higher-density inner region. In the WCER (including Beam 3 in the SCER), the HINSA is probably not associated with CO clouds, but with CO-dark or CO-faint gas.
The Nature of Low-albedo Small Bodies from 3 μm Spectroscopy: One Group that Formed within the Ammonia Snow Line and One that Formed beyond It

We present evidence, via a large survey of 191 new spectra along with previously published spectra, of a divide in the 3 μm spectral properties of the low-albedo asteroid population. One group (“sharp types,” or STs, with band centers <3 μm) has a spectral shape consistent with carbonaceous chondrite meteorites, while the other group (“not sharp types,” or NSTs, with bands centered >3 μm) is not represented in the meteorite literature but is as abundant as the STs among large objects. Both groups are present in most low-albedo asteroid taxonomic classes, and, except in limited cases, taxonomic classifications based on 0.5–2.5 μm data alone cannot predict whether an asteroid is an ST or NST. Statistical tests show that the STs and NSTs differ in average band depth, semimajor axis, and perihelion at confidence levels ≥98% while not showing significant differences in albedo. We also show that many NSTs have a 3 μm absorption band shape like comet 67P and likely represent an important small-body composition throughout the solar system. A simple explanation for the origin of these groups is formation on opposite sides of the ammonia snow line, with the NST group accreting H2O and NH3 and the ST group only accreting H2O, with subsequent thermal and chemical evolution resulting in the minerals seen today. Such an explanation is consistent with recent dynamical modeling of planetesimal formation and delivery and suggests that much more outer solar system material was delivered to the main asteroid belt than would be thought based on the number of D-class asteroids found today.

Published: July 2022

On July 2018, one specimen of Ichthyococcus ovatus (Cocco, 1838) was caught in the Strait of Sicily during the International Bottom Trawl Survey in the Mediterranean (MEDITS). The adult I. ovatus measured 49 mm in total length and weighed 1.44 g. In this context, the presently reported study constitutes the first and deepest record of an adult of I. ovatus as well as the morphometric description of its sagittal otoliths. In addition, we provide an age estimation as well as an update of the geographical distribution of this bathypelagic species around the Mediterranean Sea. Based on the growth increments of sagittal otoliths, the estimated age was five years. Specifically, the otolith from the presently reported specimen of I. ovatus tended to be elliptic in shape related to aspect ratio and high rectangularity while circularity showed high complexity of otolith contour complexity. The absence of economic value of rarely reported species may underestimate their abundance. Therefore, more studies and research surveys would be necessary to fill the information gap on the biology of these deep-water species.

Authors: Rinandio Dipta , Helmanto Hendra , Zulkarnaen Rizmoon , Primananda Enggal , Hamidi Arief , Robiansyah Iyan
Published: July 2022

Java is the most populous island in the world. This high population and the extensive economic activities have significantly reduced the forest areas of the Island and have greatly increased the pressure on its plant diversity. Compared to those with a wide distribution, endemic plants with a narrow geographic range are more vulnerable to anthropogenic threats and environmental changes. As species lists are essential for knowledge of species diversity in areas with strong anthropogenic pressure, here we present a dataset of endemic plants of Java Island. The initial species list was manually extracted from the Plant of the World Online (POWO). Each species on the list was then confirmed for its endemism by checking its current distribution using peer-reviewed publications, online plant databases and herbarium specimen images stored on the Global Biodiversity Information Facility (GBIF). The dataset contains 652 species in 279 genera and 85 families. The family with the highest number of endemic species is Orchidaceae (142 species), followed by Rubiaceae (57 species), Acanthaceae (40 species), Apocynaceae (35 species) and Lauraceae (29 species). The growth form of the species is mostly trees (22.6%), followed by herbs (19.2%), epiphytes (16%), shrubs (12.4%), vines (11%) and geophytes (9.4%). Most of the species (89.7%) have not yet been assessed for their conservation status according to the IUCN Red List Categories and Criteria. There are only 55 species (8.3%) that have been conserved within ex situ collections. Furthermore, most of the species (79.8%) are not listed on the CITES appendices and there are only four species (0.6%) protected by national law.

Our contribution provides the first online list of accepted scientific names of Javan endemic plants species, together with all their synonyms. New to the dataset are: i) provision of local names of the species (if available), ii) the classification of species under eleven growth forms (tree, shrub, herb, annual, graminoid, geophyte, fern, vines, hydrophyte, parasite and epiphyte), iii) assignation of the extinction risk of species according to the IUCN Red List, iv) ex situ collection status of species and information on the protection status of the species according to (v) CITES and (vi) the national law of Indonesia.

Training of future STEAM teachers: Comparison between primary degree students and secondary master's degree students
Authors: Ortega Torres Enric
Published: July 2022

In recent years, the presence of the acronym STEAM has been growing in the educational field. All around the world we are faced with a growing demand for professional STEM skills, however, who has the responsibility to train future STEAM teachers? In this article, we explain the results of an investigation with university students pursuing a degree in primary education and Master’s degree students in  secondary education, with technology speciality, participating in a seminar about STEAM projects design in two consecutive academic calendar years (18/19 and 19/20). We analyse the responses to a questionnaire which was specifically designed to discover their knowledge about STEAM and the predisposition towards its extended study with a set of semi-structured interviews to delve into the causes of the responses. Previous knowledge about the meaning of STEM and the predisposition of pre-service teachers towards the future design of projects based on the STEAM disciplines are compared. The results show significant differences between the previous knowledge and the perceptions of the teachers from both specializations: primary and secondary level. The results also confirm the low levels of prior knowledge with a slight tendency towards improvement when two consecutive courses are compared. The findings emphasize the need to integrate STEAM teacher training into official curricula.

Published: July 2022

Critical thinking skills has to be sharpened particularly during the COVID19 pandemic. This circumstance leads to the lack of students passion to apply their thinking skills in doing something necessary. Therefore, it requires a learning improving critical thinking skills. This study aims to describe the critical thinking skills of chemistry education students taking part in the lecture of Team Project Based STEM-metacognitive skills. The method utilized is a Pre-Experimental Design One-Shot Case Study consists of 130 chemistry education students taking part in 3rd and 5th semester. The 3rd semester students attend lectures on the development of chemistry learning programs (P3K) and the 5th semester students attend lectures on the basics of analytical chemistry (DDKA). The instruments utilized in this research are learning scenarios, worksheets, critical thinking test instruments, critical thinking skill assessment rubrics, and project implementation feasibility observation sheets. There are three critical thinking skills very well demonstrated by students in P3K and DDKA subjects, consist of (1) strategies and tactics, (2) providing simple explanations, and (3) providing further explanations. Two other skills, namely concluding and building basic skills shown by students in the good category. The results of this study contribute to chemistry learning in the future, thus efforts are inevitably required to train critical thinking skills for prospective chemistry teachers in order to produce teachers having good thinking skills.

Published: July 2022

The main aim of the study is to investigate the growth of oyster mushrooms in two substrates, namely straw and wheat straw. In the following, the study moves towards modeling and optimization of the production yield by considering the energy consumption, water consumption, total income and environmental impacts as the dependent variables. Accordingly, life cycle assessment (LCA) platform was developed for achieving the environmental impacts of the studied scenarios. The next step developed an ANN-based model for the prediction of dependent variables. Finally, optimization was performed using response surface methodology (RSM) by fitting quadratic equations for generating the required factors. According to the results, the optimum condition for the production of OM from waste paper can be found in the paper portion range of 20% and the wheat straw range of 80% with a production yield of about 4.5 kg and a higher net income of 16.54 $ in the presence of the lower energy and water consumption by about 361.5 kWh and 29.53 kg, respectively. The optimum condition delivers lower environmental impacts on Human Health, Ecosystem Quality, Climate change, and Resources by about 5.64 DALY, 8.18 PDF*m2*yr, 89.77 g CO2 eq and 1707.05 kJ, respectively. It can be concluded that, sustainable production of OM can be achieved in line with the policy used to produce alternative food source from waste management techniques.
Uncertainty measures from partially rounded probabilistic forecast surveys
Authors: Glas Alexander , Hartmann Matthias
Published: July 2022

Although survey‐based point predictions have been found to outperform successful forecasting models, corresponding variance forecasts are frequently diagnosed as heavily distorted. Professional forecasters who report inconspicuously low ex ante variances often produce squared forecast errors that are much larger on average. In this paper, we document the novel stylized fact that this variance misalignment is related to the rounding behavior of survey participants. Rounding may reflect the fact that some survey participants employ a rather judgmental approach to forecasting as opposed to using a formal model. We use the distinct numerical accuracies of panelists' reported probabilities as a way to propose several alternative and easily implementable corrections that (i) can be carried out in real time, that is, before outcomes are observed, and (ii) deliver a significantly improved match between ex ante and ex post forecast uncertainty. According to our estimates, uncertainty about inflation, output growth and unemployment in the U.S. and the Euro area is higher after correcting for the rounding effect. The increase in the share of nonrounded responses in recent years also helps to understand the trajectory of survey‐based average uncertainty during the years since the financial and sovereign debt crisis.
Minimizing sensitivity to model misspecification
Authors: Bonhomme Stéphane , Weidner Martin
Published: July 2022

We propose a framework for estimation and inference when the model may be misspecified. We rely on a local asymptotic approach where the degree of misspecification is indexed by the sample size. We construct estimators whose mean squared error is minimax in a neighborhood of the reference model, based on one‐step adjustments. In addition, we provide confidence intervals that contain the true parameter under local misspecification. As a tool to interpret the degree of misspecification, we map it to the local power of a specification test of the reference model. Our approach allows for systematic sensitivity analysis when the parameter of interest may be partially or irregularly identified. As illustrations, we study three applications: an empirical analysis of the impact of conditional cash transfers in Mexico where misspecification stems from the presence of stigma effects of the program, a cross‐sectional binary choice model where the error distribution is misspecified, and a dynamic panel data binary choice model where the number of time periods is small and the distribution of individual effects is misspecified.

Published: July 2022

In this paper we present techno-typological and raw material analysis of the Mousterian lithic assemblage from Vinica cave (Hrvatsko zagorje, Croatia) excavated during late 1990s and early 2000s. Lithic artefacts are found in two Mouste- rian layers, c and d, whose age is determined by 14C AMS dating. Sample from layer d brought indefinite age older than 50,300 years BP while calibrated age for the sample from layer c is 36–34.5 ka BP. Quartz is predominant raw material in both layers followed by different cherts. Quartz cobbles were knapped on-site while at least some chert artefacts were not flaked in the cave but brought from elsewhere as blanks and tools. Among small number of tools, scrapers are the most frequent. Small lithic assemblages from both layers suggest that cave was used as short term Neandertal camp during Middle Paleolithic.

En este trabajo se presentan los anglicismos léxicos registrados en el Diccionario castellano con las voces de ciencias y artes (1786-1793) de Esteban de Terreros, una parcela léxica hasta la fecha ignorada a pesar de su relevancia. Nuestra hipótesis de partida se basa en el supuesto de que el francés fuera la vía de introducción de los anglicismos en castellano, y que los diccionarios galos desempeñaran un papel muy importante, como el Dictionnaire (1752) de Trévoux. Varios de los casos léxicos analizados van a gozar de arraigo en español hasta la actualidad.

Este estudio analiza el marcado diferencial de objeto (DOM) en la variedad del castellano en contacto con el catalán en la segunda mitad del siglo XIX. En concreto se estudian dos corpus escritos en castellano en la ciudad de Tarragona (Cataluña), con diferentes grados de formalidad, y se comparan con un tercer corpus de cartas en español y remitidas desde zonas sin contacto con otras lenguas. Nuestro análisis confirma que el contacto español-catalán limita el avance del DOM, que se muestra también sensible a otros factores como el registro.

Neste trabalho a surdez é compreendida como uma experiência visual entendida fora do campo da medicalização, e os surdos como um grupo múltiplo e multifacetado, ainda problematizamos as representações da surdez e o modo como vem sendo historicamente inventada e destacamos trechos de reportagens da grande mídia a fim de tecer, a partir da escola, tensionamentos a respeito da enunciação que é forjada a cerca dos surdos em nossa sociedade através dos meios de comunicação de massa. Atualmente existe um campo de conflitos em que se disputam sentidos sobre a surdez e ser surdo com diferentes representações, entre concepções clínicas e antropológicas. Observa-se que a enunciação que é feita está majoritariamente carregada por uma perspectiva ouvintista que busca a oralização e ciborguização dos corpos ditos anormais. Por fim, problematizamos que, mesmo em meio à forte presença ainda ativa do Oralismo em nossa sociedade, há também iniciativas micropolíticas de produção de discursos que contribuem para afirmar a surdez em sua diferença.

Concluímos que a experiência foi bem sucedida, porém sem desconsiderar os impactos concretos da má gestão brasileira durante a pandemia.
A INFÂNCIA E A EDUCAÇÃO A PARTIR DA OBRA DE MODO ADDISCENDI DE GILBERTO DE TOURNAI NO SÉCULO XIII
Authors: Silva Andrei Roberto da , Moraes Juliana de Mello
Published: July 2022

Em 1263, Gilberto de Tournai (1209-1284) finalizou a obra De modo addiscendi, um tratado pedagógico destinado a Jean Dampierre.  Esse texto foi produzido em Paris no século XIII, momento de crescimento das instituições educacionais. O autor da obra foi um frade franciscano, mestre de teologia na Universidade de Paris e conselheiro do rei Luís IX da França. Na obra, Gilberto orienta os mestres e familiares a educar as crianças para que tenham uma formação espiritual e intelectual. A partir desta obra, o objetivo é analisar as representações da infância e da sua educação no período. Para tanto, utilizamos o conceito de representações de Roger Chartier (2002) e Jacques Verger (1999) para abordar o ensino medieval. Esta pesquisa é qualitativa e documental. O estudo indica que as representações forjadas por Tournai inscrevem a infância como um período de formação, na qual os esforços do mestre deveriam fomentar a submissão e a obediência, propiciando o desenvolvimento da sabedoria. A análise da obra de Tournai corrobora a perspectiva de que a educação se conectava aos modos de pensar e caracterizar a infância, bem como da importância da Igreja católica para a constituição e difusão de representações sobre a infância na época.

Rice provides a balanced diet, and regular rice consumption helps maintain a healthy life and prevents many common illnesses. Amylose content and gelatinization temperature are considered major physicochemical factors which significantly affect the nutrition and cooking quality of rice. The Waxy (Wx) gene controls the synthesis of amylose in the endosperm and the ALK gene controls the gelatinization temperature of rice. Both genes are present on chromosome 6. Improving the rice traits is crucially essential to the cultivators and the consumers to overcome the increasing demand for high-quality and nutritionally rich rice. Many studies have been successfully conducted to improve the agronomical traits of rice. However, the concern for improving nutrition and cooking quality-related traits of rice is less common among the breeders. Therefore, considering the current trends, introducing consumer-friendly novel varieties that can fulfill the nutritional requirements is essential to face the increasing domestic demand for high-quality rice. In the present study, we used frequently grown 54 local rice varieties and carried out a marker-based genetic analysis for three traits: amylose content, gelatinization temperature, and yield. Then statistical analysis was carried out using quantitative data of different agronomical and physicochemical traits to identify the correlation and potential to improve such essential traits. The level of amylose content is significantly associated with the gelatinization temperature indicating that AC and GT have a positive correlation. The DNA markers SSIIa and Seq1-2 markers showed monomorphic patterns indicating the narrow genetic basis of the rice varieties tested. This study revealed that existing high-yielding rice varieties could be successfully employed to increase the amylose content while decreasing the level of gelatinization temperature through breeding strategies to make nutritionally rich consumer-friendly novel varieties.
Eruptive basal cell carcinoma and lenalidomide: rising awareness among dermatologists
Authors: Pagliarello Calogero , Girardelli Carlo Renè , Stanganelli Ignazio
Published: July 2022

Lenalidomide (L) is approved for treating multiple myeloma (MM), being preferred to its parent drug, thalidomide, for its superior safety. We report the case of a patient developing more than 10 basal cell carcinomas (BCCs) within 1 month of starting L. Notably, his treating hematologist neither recommended sun avoidance nor alerted him to this possible side effect. Moreover, not even the referring dermatologist was capable of linking the eruption of BCC to L. The tendency of L to promote BCCs may be underreported compared with other hematological drugs with known dermatological side effects such as hydroxyurea.

The GEM program has facilitated the availability of new and converted surficial geology maps and associated digital datasets for large sectors of northern Canada, leading to about 70% of the north being mapped and digitally available. Development of the
Surficial Data Model (SDM) and Canadian Geoscience Map (CGM) series have streamlined the publication process and created a common standard digital map format and geodatabase. Based on traditional and more recent remote predictive mapping methodologies, there are now three types of surficial geology
CGM maps produced: Surficial Geology, Reconnaissance Surficial Geology, and Predictive Surficial Geology. The considerable number of new surficial geology maps published during GEM-1 and GEM-2, as well as upcoming map publications, has resulted in an increase of 12% map coverage north of 60?,
constituting a significant and lasting legacy of the GEM Program.
A conjecture strengthening the Zariski dense orbit problem for birational maps of dynamical degree one
Authors: Bell Jason , Ghioca Dragos
Published: July 2022

We formulate a strengthening of the Zariski dense orbit conjecture for birational maps of dynamical degree one. So, given a quasiprojective variety X defined over an algebraically closed field K of characteristic
$0$
, endowed with a birational self-map
$\phi $
of dynamical degree
$1$
, we expect that either there exists a nonconstant rational function
$f:X\dashrightarrow \mathbb {P} ^1$
such that
$f\circ \phi =f$
, or there exists a proper subvariety
$Y\subset X$
with the property that, for any invariant proper subvariety
$Z\subset X$
, we have that
$Z\subseteq Y$
. We prove our conjecture for automorphisms
$\phi $
of dynamical degree
$1$
of semiabelian varieties X. Moreover, we prove a related result for regular dominant self-maps
$\phi $
of semiabelian varieties X: assuming that
$\phi $
does not preserve a nonconstant rational function, we have that the dynamical degree of
$\phi $
is larger than
$1$
if and only if the union of all
$\phi $
-invariant proper subvarieties of X is Zariski dense. We give applications of our results to representation-theoretic questions about twisted homogeneous coordinate rings associated with abelian varieties.

Authors: Chen Tian
Published: July 2022

Introducción. En la era digital, las redes sociales como WeChat, QQ, Sina Weibo y TikTok, etc. son una herramienta indispensable entre los universitarios chinos para comunicarse y divertirse en la vida cotidiana, pero también para hacer compras en línea. En los últimos años, hacer compras en las redes sociales se ha convertido en un nuevo modelo de compra online y en un comportamiento muy popular entre la juventud china. Objetivos. El presente trabajo trata de resolver los siguientes interrogantes: ¿Qué tipo de impactos está generando este uso y consumo en los y las jóvenes de China? ¿Y sobre los nuevos modelos de negocios chinos? Metodología. Se procede al análisis de estos interrogantes, examinamos la red social más atractiva entre los universitarios de la ciudad de Nanjing y observamos sus características y peculiaridades de usos y consumos. Para ello, investigamos el uso de las redes sociales como herramientas de marketing sobre una muestra compuesta por un total de 436 estudiantes de 20 universidades de Nanjing en 2020. Mediante software SPSS analizamos la correlación entre el grado de atención de los estudiantes encuestados a los productos recomendados en las redes sociales, el grado de confianza de dichos productos recomendados y el grado de frecuencia de compra. Al mismo tiempo, también aplicamos análisis de regresión múltiple para analizar el grado de confianza y atención de los estudiantes universitarios hacia los productos recomendados en redes sociales y la frecuencia de compra. Resultados. Los principales entre ellos nos indican que: la frecuencia de compras de los estudiantes universitarios a través de las redes sociales está más estrechamente relacionada con la atención al producto (0,646), seguida por el grado de confianza en los productos (0,625), siendo la correlación entre el grado de confianza en el producto y el grado de atención la más pequeña (0,549). Conclusiones. En consecuencia, los coeficientes de correlación entre los grados analizados son estadísticamente significativos, es decir, existe una correlación entre los tres. El uso de las redes sociales como herramienta de marketing sí tiene un impacto positivo en las compras online de los estudiantes universitarios, en especial, se concluye que tanto la confianza de los universitarios en los productos recomendados por las redes sociales como su atención a los productos recomendados tienen un impacto positivo y significativo en la frecuencia de compra de estos productos.

Thymelaea microphylla is an edible and medicinal species that exhibits high antioxidant activity and phenolic content. Moreover, four fractions (hexane, dichloromethane, methanol and water) were tested towards their ex-vivo antioxidant, anticancer, anti-inflammatory and antiviral effects. Dichloromethane fraction had marked protection against cell oxidative stress (IC50 = 1.5 µg/mL). Hexane, Dichloromethane and Methanol fractions exhibited prominent anti-proliferative activities against cancer cells especially A-549 cells, with very low IC50 values of 0.13, 0.018 and 0.5 µg/mL, respectively (50, 101 and 14 higher than Etoposide). Moreover, the three fractions showed no cytotoxicity on normal fibroblast WS-1. DCM exhibited high anti-inflammatory activity in RAW 264.7 cells. Theses fractions were also tested on herpes (HSV-1). MeOH fraction was the most active acting both directly on the virus and on its adsorption. Phenolics, terpenoids and saponins were the major classes. These findings demonstrate that T. microphylla is a very promising source of selective anticancer molecules.

Evaluation of medicinal plants for their antidiabetic activities has increased considerably around the world as well as in Algeria. Olea europaea, commonly called Zeytoune, is traditionally used by Tlemcen population in Algeria, for treating diabetes mellitus.

In this work, we evaluate the capacity of O. europaea leaves crude extracts to inhibit in vitro α-amylase activity.

The qualitative phytochemical screening carried out on O. europaea leaves extracts showed the presence of tannins, sterols and triterpenes, saponins, flavonoids and terpenoids. A quantitative analysis of the crude extracts showed significant levels of total polyphenols and flavonoids in hydroacetonic extract, with an amount of 802.57 ± 0.001 mg GAE/ g and 359 ± 0.002 mg CE/ g, respectively. In vitro tests carried out on the inhibitory of α-amylase activity, revealed an inhibitory effects, specifically with hydroacetonic extract in a concentration-dependent manner, with an IC50 value of 0.27 ± 0.02 mg/mL. These findings reveals that O. europaea leaves extracts could represent an interesting source of bioactive compounds and allow to the development of new antidiabetic agents.

Published: July 2022

In this study, cyanobacterial communities in mucilage samples collected from three stations in the Dardanelles Strait were analyzed with a metagenomic approach. Mucilage samples were collected at the beginning of June 2021 from three points of the Dardanelles (Station 1: 40°6'42.78"N, 26°23'57.00"E; Station 2: 40°9'8.09"N, 26°24'16.19"E; Station 3: 40°6 '21.62"N, 26°22'41.25"E). The dominant cyanobacteria were Prochlorococcus marinus (39.17%), Synechococcus sp. (20.85%), Lyngbya sp. (12.00%), Trichodesmium erythraeum (7.33%), Aphanocapsa sp. (4.33%) and Leptolyngbya sp. (3.33%), which constituted 87.00 % of the total number of sequences. In this study, cyanobacteria species that can cause harmful algal blooms and have toxic effects on the mucilage structure have been determined. The Marmara Sea and the Dardanelles Strait, which have been affected by serious disturbances, including industrial activities, anthropogenic impacts, tourism and artificial lighting, will never be fully restored to their former ecological state. In addition, cyanobacteria species in the mucilage may cause harmful algal blooms and have toxic effects that threaten the future well-being of coastal populations and ecosystem stability. Thus, the government and local authorities should pay more attention to combating the mucilage.
Cestode Infection of the Native Brine Shrimp (Artemia parthenogenetica) in Çamaltı Saltpan (İzmir/Türkiye)
Authors: KORU Edis
Published: July 2022

Artemia sp. populations in saltworks throughout the world have been gaining importance due to their extensive use in aquaculture and their importance as the main prey organism for aquatic birds in hypersaline ecosystems. The genus Artemia sp. is also known as the intermediate host of some cestode species that are associated with flamingos. In this study, Flamingolepis liguloides parasitism was determined in Artemia partenogenetica for the first time in Turkiye. Infected A. parthenogenetica was detected in İzmir Çamaltı saltpans between May-August 2018 and the parasite diagnosis was made. Parasites were detected near the abdomen, thorax and the intestinal tract of A. parthenogenetica. The prevalence of parasites was higher in adult Artemia (63.6%). The presence of F. liguloides in A. parthenogenetica was very high with a frequency of 72.2%. The most abundant and prevalent parasite infection was recorded in July which is the most suitable time of the year with respect to number of flamingos in the area. The results show the prevalence of this parasite infection in A. parthenogenetica, which may be important for both the local Artemia population in the area and the flamingos breeding in Çamaltı saltpans.
