Authors: Sabbatini A. , Bonatto S. , Gooday A. J. , Morigi C. , Pancotti I. , Pucci F. , Negri A.
Published: June 2022

Sediment subsamples (0-2cm layer, >63Âµm fraction) from box cores taken at four sites (Stns 120, 121, 122, 123) located along a transect in theGulf of Trieste (water depth range 8-22m)were sorted for foraminifers, including soft-walledmonothalamous taxa (organic-walled allogromiids, agglutinated saccamminids and psammosphaerids). The distribution of foraminiferal species differed among samples, corresponding to differences in water depth, granulometry, distance from fresh water source and other chemical and physical parameters (temperature, salinity and dissolved oxygen). In general, the absolute and relative abundance of monothalamous foraminifers tended to decrease with distance from the coast, i.e. with distance from the inflow of the Isonzo River, whereas polythalamous taxa exhibited the opposite trend. Therewas also a switch in dominance by polythalamous agglutinated species at Stn 122 to polythalamous calcareous species at Stn 123. Among polythalamous foraminifers, the calcareous species Ammonia perlucida was dominant at the innermost station (Stn 120), together with the agglutinated species Cribrostomoides spp. and Haplophragmoides spp. These species were absent or less common at the other stations. Textularia agglutinans was abundant at the two inner stations (121, 122). Stn 122 was further characterized by Reophax nana, Leptohalysis scottii and the calcareous species Nonionella stella. The latter is also themost abundant taxa at the outer station (Stn 123) where the agglutinated taxa Reophax nana and Textularia conica are alsowell represented. All themonothalamous taxa found are previously unreported from North Adriatic waters; all are undescribed at the species level and, in most cases, at the generic level also. Two genera (Psammophaga, Vellaria), however, are common in other shallow-water settings and Micrometula, previously known from habitats ranging from coastal to deep sea, is also present. One of the allogromiid morphotypes closely resembles Goodayia rostellaum, recently described from the Black Sea. Psammophaga and Vellaria are also known from the Black Sea, but the populations are probably distinct at the species level.

Authors: Ozcan Ercan , Less Gyorgy , Baldi-Beke Maria , Kollanyi Katalin
Published: June 2022

We present the most complete record of Rupelian to Chattian hyaline larger foraminifera in Mediterranean Tethys from Keleresdere section (Mus region, eastern Anatolia) based on the biometric study of such stratigraphically important groups as Miogypsina, Miogypsinoides, Nephrolepidina, Eulepidina, Nummulites, Cycloclypeus, Heterostegina, Operculina and Spiroclypeus. The identified taxa, most of which are described for the first time in Turkey and represent the Shallow Benthic Zones 22A, 22B, 23, enable us to correlate them with comparativelywell-known coeval taxa from other parts of the Tethys. Our data suggest that the populations of Miogypsinoides, Eulepidina, Nephrolepidina and Cycloclypeus are represented by more than one lineage for each of these groups during Oligocene. Some new taxa such as Nephrolepidina musensis n. sp., Eulepidina anatolica n. sp. and Cycloclypeus pseudocarpenteri n. sp. are introduced. The stratigraphic position of Eulepidina elephantina, highly disputed in previous works, was re-evaluated based on its occurrence in the late Chattian. We for the first time demonstrate the parallel evolution of Miogypsina and Miogypsinoides in the late Chattian of eastern Mediterranean region. Miogypsinoides formosensis is associated with Miogypsina basraensis at the lower part of upper Chattian and this association is accompanied by Miogypsinoides sivasensis at the uppermost part of the section. We compare our results with the available data from other parts of Tethys and remarks on Rupelian-Chattian boundary and the zonation of shallow-marine Oligocene of Mediterranean Tethys are made.
Late Miocene freshwater phytoplankton from Jozefina (Poland)
Authors: Worobiec Elzbieta
Published: June 2022

The paper presents results of detailed investigation of freshwater microalgae from the Upper Miocene deposits from Jozefina (Krakow-Silesia Upland, central Poland). During the studies 28 microphytoplankton species of the genera Sigmopollis, Geiselodinium, Botryococcus, Ovoidites, Cycloovoidites, Stigmozygodites, Diagonalites, Tetraporina, Spintetrapidites, Closteritetrapidites, Planctonites,Cystidiopsis, Zygodites, and Pseudoschizaea were identified. One new species, Closteritetrapidites pacltovae sp. nov. has been proposed. Most of the recorded algae preferred meso-to eutrophic, stagnant or slowly flowing shallow waters. The presence of resting cells – e.g. zygospores of Zygnemataceae (Mougeotia, Spirogyra, and Zygnema) and desmids (Closterium), suggests that the water body (bodies) might periodically dried out. The occurrence of Pseudoschizaea is characteristic forwarm climate, possibly with seasonal moisture fluctuations. Occurrence of determined species in various localities (listed in synonyms) suggests that these algae were widespread in the past.

Published: June 2022

Larger foraminifera of the Tertiary a1 (Thanetian) to Tertiary b (Priabonian) of the Far Eastern Letter Stages are recognized in the upper Paleocene to upper Eocene limestones of Jaintia Hills, Meghalaya. The occurrence of Pellatispira preceded both occurrences of Lepidocyclina spp. and Nummulites fabianii. Three new genera and species, Meghalayana indica, n. gen., n. sp., Raoia indica, n. gen., n. sp., and Protogypsina indica, n. gen., n. sp. are described after Orbitosiphon tibetica, Paleocene orbitoidal foraminifera as a group with Orbitosiphon.
American Miogypsinidae: An analysis of their phylogeny and biostratigraphy
Authors: BouDagher-Fadel Marcelle K. , Price G. David
Published: June 2022

Over 1000 samples from cores and cutting from 37 wells from offshore South America have been investigated and have provided new insight into the evolution of the miogypsinids. For the first time Paleomiogypsina, a genus first described from the Late Oligocene of Japan, is reported from the Early Oligocene of the American province. One new genus, Americogypsina and 18 new species, Neorotalia sp. 1, Paleomiogypsina braziliana, P. americana, Americogypsina braziliana, A. americana, A. koutsoukosi, Miogypsinella elongata, Mlla matsumaria, Mlla sp. 1, Miogypsinoides praegunteri, Mdes sp. 1, Miogypsinodella braziliana, Miogypsina triangulata, M. americoprimitiva, Miolepidocyclina braziliana, Ml. sp. 1, Ml. sp. 2, Ml sp. 3 are described. The American regional evolutionary lineages of the miogypsinids taxa are described, starting in the Early Oligocene and ending in the Early Miocene. Their phylogenetic lineages are similar to those of the Tethyan miogypsinids, however the stratigraphic ranges of the main genera and their species are different, as the American miogypsinids made their first appearance earlier than their morphologically similar Tethyan counterparts.
Observations on two Late Cretaceous species of Lepidodiscus Witt (Bacillariophyta) from Devon Island, Canadian High Arctic
Authors: Witkowski Jakub , Harwood David M.
Published: June 2022

A recently discovered deposit of Late Cretaceous diatoms on Devon Island contains exceptionally well-preserved siliceous microfossils. Two diatom taxa from this deposit, previously identified as belonging to the genera Actinodictyon and Lepidodiscus, were examined with light and scanning electron microscopy. The present study revealed that these two taxa belong to the genus Lepidodiscus. Both were found to display an extremely complex structure of their radially and concentrically undulate valves, involving porous canals, hyaline areas and an external network of thick costae locally thickened to form tubercles. Different number of alternating depressed and elevated sectors located in the marginal zone of the valve, and different structures associated with the external openings of marginal rimoportulae were found to be a sufficient basis for erecting a new species, Lepidodiscus annamariae sp. nov. The excellent preservation of the Devon Island material also allowed for a documentation of the structure of the girdle, composed of multiple open bands.
Ypresian Nummulites from the Nile Valley and the Western Desert of Egypt: Their systematic and biostratigraphic significance
Authors: Boukhary Mohamed , Hussein-Kamel Yasmine F. , Abdelmalik Wagih , Besada Mohsen
Published: June 2022

Nine Nummulites species: Nummulites fraasi De La Harpe 1883, Nummulites luxorensis Boukhary, Hussein- Kamel and Abdelmalik n. sp., Nummulites dandaraensis Boukhary, Hussein-Kamel andAbdelmalik n. sp., Nummulites rotularius Deshayes 1838, Nummulites subramondi De La Harpe 1883 (Topotype material from Gebel Deir, near Esna) sensu Schaub 1951,Nummulites thalmanni Schaub 1981, Nummulites aff. arnii Schaub 1981, Nummulites ornatus Schaub 1951 and Nummulites cailliaudi D’Archiac and Haime 1853 (Topotype material from Garra El Hamra, Bahariya Oasis) are described from Ypresian rocks in the Luxor-Minia reach of the Nile Valley and also from the region ofBahariya oasis. The study of the larger foraminifera from these two localities enables us to correlate the Thebes Formation in the Luxor- Qena stretch in the Nile Valley with the Minia Formation in some localities as in G. Drunka, Wadi Gabrawi, Assiut environ and Beni Hassan. The investigated strata could be also equated to the Naqb andQazzun Formations in Bahariya Oasis, where the Naqb Formation is found to be correlatable with the Nusf and Farafra Formations, both underlying the Qazzun Formation. The Thebes-Minia sequence could be also correlatedwith a recently described sequence from Northern Galala in the EasternDesert (Boukhary et al. 2009). The identified biozones match well with the SBZ 10 – SBZ 12 zones of Serra – Kiel et al. 1998.

Published: June 2022

The study of the foraminifera and ostracodes from the Ummer Radhuma Formation in five wells of the Dukhan Oil Field in Western Qatar allows to reevalute the age of the type-levels of the larger rotaliid foraminifera first described by Smout in his classical paper in 1954 as Early Eocene (late Ypresian, zones P8/9 respectively E6/7 of Berggren and Pearson 2006a). During the Early Eocene, a rather uniform depositional environment prevailed in a large part of the Arabian Platform as indicated by the close similarity of the microfaunas of Western Qatar to those of the same age in the Rub alKhali in Saudi Arabia (Hasson 1985), Wadi Rusayl inOman, (Racey 1995), Shabwa in southwestern Yemen (Ismail and Boukhary 2008) and this fauna extends eastwards to Tibet (Wan 1991). The environment of deposition of Ummer Radhuma was marine and most probably sheltered lagoon that prevailed during the Ypresian of Qatar. The planktonic and the larger rotaloid foraminifera and the ostracodes are illustrated and discussed briefly.
Pessagnoites, a new foraminifer genus from the Upper Cretaceous of the Austin Chalk, northeast Texas
Authors: AlShuaibi Arafat A.
Published: June 2022

A new genus Pessagnoites is described from the Austin Chalk of Northeast Texas. This taxon is included in the Marginotruncanidae and is characterized by possessing an extraumbilical-non umbilical in position primary aperture and sutural supplementary apertures both on the spiral and umbilical sides of the test. Pessagnoites n. gen. marks the base of the lowermost Coniacian (Superzone UK4, Zone 4B) in Texas. Its co-occurrence with Cremnocreamus deformis erectus herein suggests its placement as a primary marker taxon marking the base of the Coniacian worldwide.
Shanita thawtinti, a new milioloid foraminifer from the Middle Permian of Myanmar
Authors: Win Zaw , Aung Htun Hla , Shwe Kyi Kyi
Published: June 2022

Shanita thawtinti n. sp. is proposed for a pillared milioloid foraminifer found from Middle Permian strata of the Nwabangyi Formation of the Plateau Limestone Group, exposed in the western Shan Plateau of Myanmar. The new species is characterized by its extraordinary large size of mature test and large numbers of volutions. In contrast to the previously assigned ages for other species of Shanita, the age of the new species is considered to be Murgabian (=Wordian) based on the occurrence between beds of the index fusulinacean species, Neoschwagerina craticulifera below and Neoschwagerina margaritae above.
A new bleaching method for strongly oxidized palynomorphs
Authors: Buratti Nicoletta , Cirilli Simonetta
Published: June 2022

An alternative bleaching method to process highly oxidized palynofacies, characterized by undeterminable dark-hued palynomorphs is described. This procedure has been found useful in obtaining palynomorphs sufficiently translucent for transmitted light microscopic examination. It is performed after the main standard stages of palynological processing procedures and is based on controlled lengthy bleaching by sodium hypochlorite (NaOCl, common household bleach). This method promotes the use of a mild medium which is less dangerous than the oxidants commonly used for bleaching. It is a safemethod for both laboratory operators and the environment since it can be performed out of a fume cupboard using low concentrations of NaOCl solution. Compared to other bleachingmethods, it is inexpensive, simple, relatively quick and adaptable. The goal of this study is to improve the value of palynomorphs as relative age indices in continental-paralic successions, typically characterized by strongly oxidized palynofacies and frequently barren of other fossils.
Early Cretaceous Theriosynoecum Branson 1936 in North America and Europe
Authors: Sames Benjamin
Published: June 2022

The revision of Theriosynoecum Branson 1936, a common ostracod genus of Middle Jurassic to Early Cretaceous nonmarine deposits worldwide, demonstrates that its representatives–particularly the Early Cretaceous North American ones–are not as endemic as hitherto assumed. The taxonomic concept applied herein resolves many problems resulting from an overestimation of the taxonomic (in-)significance of some ornamentation elements in the genus as well as the too regional view of the faunas during the second half of the 20th century. This is the first step to a supraregional biostratigraphic and improved paleoecologic application of representatives of the extinct genus Theriosynoecum (Cytheroidea, Limnocytheridae, Timiriaseviinae). Theriosynoecum fittoni (Mantell 1844) and Theriosynoecum alleni (Pinto and Sanguinetti 1962) are proposed for being synonymous because of their many striking similarities. The species Theriosynoecum forbesii (Jones 1885) and T. verrucosa (Jones 1885) are considered separate and not subspecies of T. forbesii. Theriosynoecum verrucosa occurs in the uppermost Morrison Formation of the Black Hills area, South Dakota, U.S.A., Theriosynoecum fittoni in the Lakota Formation of the same area. Theriosynoecum pahasapensis (Roth 1933) is, thus far, endemic to North America. A key to the described species is presented. Early Cretaceous species of Theriosynoecum are not yet as applicable biostratigraphically in North America as in Europe (e.g. the English Purbeck/Wealden), but this is due to the lack of data from the former area and considered to be promising once more data are available. Nevertheless, the "classic" taxonomic approach provides a considerable step towards better application of these taxa as well as future analysis and robust discussion regarding the phylogeny, evolution and distribution of the limnocytherid subfamily Timiriaseviinae. The genus Metacypris is now restricted to an Aptian to recent lineage of small, weakly monosulcate Timiriaseviinae. Middle Jurassic to Early Cretaceous bisulcate and large taxa formerly designated as Metacypris are now assigned to Theriosynoecum.
Glossary of morphologic terms of late Mesozoic nonmarine Ostracoda, relevant to Theriosynoecum Branson 1936 and Cypridea Bosquet 1852
Authors: Sames Benjamin
Published: June 2022

Despite the fact that the number of publications on the morphologic terms of ostracod carapace features is impressive, definitions, use and interpretation of many terms remain inconsistent and therefore fraught with problems. A particular problem is the application of certain terms of morphologic features in different ostracod groups without the consideration of their potentially different origin, genesis and nature. This revised and annotated glossary focuses on nonmarine ostracods, families Timiriaseviinae (Cytheroidea, Limnocytheridae) and Cyprideidae (extinct, Cypridoidea), particularly on the extinct genera Theriosynoecum and Cypridea in its selection of terms and given examples, and is strongly connected with the preceding papers of this issue (Sames 2011a, b) which also include the supporting illustrations. It as well comprises detailed discussions on the origin and differentiation of the taxonomic or otherwise significance of selected carapace features, particularly ornamentation. Herein, ornamentation is subdivided into area-wide and local ornamentation elements for that reason. In contrast to their patterns of distribution, the presence of local ornamentation elements as well as their degree of expression are considered of no, or rather low, taxonomic significance. If applicable, local ornamentation elements can be used for paleoenvironmental interpretations or to identify juveniles in some cases (e.g. in Cypridea). Type, occurrence and shape of area-wide ornamentation elements are, by contrast, always taxonomically relevant to a certain degree. As to the Family Cyprideidae, the alveolar ridge is newly introduced and defined, and the terms for the anteroventral (alveolus and its elements) and posteroventral regions (cyathus, cyathus-like protrusion) are redefined and discussed. A morphologic term can never be a matter of common or collective knowledge as long as its appreciation and usage differs between researchers. In fact, the accuracy of its usage can only be identified when we know that we are talking about the same thing. With this glossary it is intended to better communicate the views of the author, to integrate new insights into ostracod paleobiology into the interpretation of carapace features, and to propose a kind of harmonization between different concepts as well as to put these up for discussion and further development.
High rank taxa of Polycystina (Radiolaria) as environmental bioindicators
Authors: Kruglikova Svetlana B. , Bjorklund Kjell R. , Hammer Oyvind
Published: June 2022

Analyses based on complete faunas are more reliable than those based on a few species. To minimize errors in identification due to geographical and ecological variations in skeletal morphology, as well as taxonomic "noise" caused by ontogenetic stages, the polycystine radiolarian fauna was grouped into 20 high-rank taxa (HRT); 12 Spumellaria and 8 Nassellaria families. Every region or local province has a characteristic "HRT-assemblage" on either the family/subfamily or the suborder/order level,with very specific quantitative ratios. The polycystine assemblages of theNorwegian fjords and the Norwegian Sea contain essentially the same set of species, but data on the HRT show differences between the offshore and fjord associations, and between the main fjords and their tributaries. We show herein that HRT can be used not only in the Norwegian Sea, but also in most of the climatic zones of the Pacific. We used 21 published surface sediment samples along longitude 175°E between latitudes 48°N and 14°S in the western Pacific Ocean, documenting the relationships between the modern distribution of radiolaria and the present oceanographic conditions. The low-rank and high-rank approaches gave nearly identical results for this data set. Factor analysis produced essentially the same four factors using low-rank and high-rank taxa, but with different eigenvalues. Temperature reconstruction based on the factor analysis of high-rank taxa was also successful.
A new melanosclerite, Melanosteus indica nov. sp. (?Cnidaria) from the Shiala Formation of the Garhwal Tethyan Himalaya, India
Authors: Trampisch Claudia , Sinha Hareshwar N.
Published: June 2022

Well preserved pleuridia attributed to the problematic group known as melanosclerites have been discovered in Upper Ordovician greenish-grey silty shales of the Shiala Formation of the Tethyan Garhwal Himalaya of India. This material is attributed to genus Melanosteus, which has also been reported from Ordovician and Silurian erratic boulders of the Baltic region, as well in Devonian Upper Gaspe Limestones from the Gaspe Peninsula, Canada. The new species Melanosteus indica comes from below the Ordovician-Silurian boundary as established by acritarchs from the same section.
Sanctus sinaicus n. gen., n. sp. (Foraminiferida, Amphisteginidae) from Late Eocene of Sinai, Egypt
Authors: Boukhary Mohammed , Abf-Elshafi Ezzat , Mattar Yousry
Published: June 2022

Sanctus sinaicus nov. gen et sp. is described from material collected in the uppermost part of the Khaboba Formation and througout the Tanka and Tayiba formations of Wadi Thal and Wadi Matulla in West–Central Sinai. We assign this new genus and species to the Late Eocene according to associated planktonic foraminiferal assemblages. Its test is symmetrical in axial sectionwith the division of chambers in the same section similar to that of amphisteginids in their early ontogenetic stage and lacks a canal system. In comparing Sanctus sinaicus with related amphistegenid species, such as Penoperculoides cubaensis Cole and Gravell 1952 from the Caribbean; Penoperculoides rozlozsniki (Mehes) (ex: Nummulites rozlozsniki Mehes) from Hungary; and "Non Nummulites rozlozsniki" described by Sander 1962, from the Dammam Formation of Saudi Arabia, we find that Sanctus sinaicus is similar to P. cubaensis in the type of coiling and the character of the umbo, which lacks alar prolongations, a canal system and transverse trabeculae, and differs from species of Nummulites in the central subdivision of chambers.
Test wall ultrastructure and taxonomic position of the foraminiferal genus Strictocostella Patterson 1987
Authors: Mikhalevich A.-V.
Published: June 2022

The details of the shell wall ultrastructure of Strictocostella matanzana (Palmer and Bermudez) 1936 and Strictocostella matanzana (Palmer and Bermudez) 1936 perytae subsp. nov. are investigated for the first time. This study shows that the calcareous shell wall of these two subspecies is monolamellar, consisting of one layer of crystals aligned in a radial direction. This fact necessitates changing the taxonomic position of the genus from the class Rotaliata which is characterized by a bilamellar shell wall to the class Nodosariata whose representatives have a monolamellar shell wall. Some other unique details of the shell and wall structure of the two subspecies studied are also described. The suborder Stilostomellina Saidova 1981 is reinstated and its rank is elevated to that of order.
A light in the dark: open access to medical literature and the COVID-19 pandemic
Authors: Capocasa Marco , Anagnostou Paolo ,   University of Rome, Italy, Bisol Giovanni Destro ,   University of Rome, Italy
Published: June 2022

Introduction. This study was designed to evaluate the accessibility of peer-reviewed literature regarding COVID-19 and the ten diseases with the highest death toll worldwide. Method. We conducted extensive searches of studies concerning COVID-19 and other diseases using the Web of Science, and the Google and Google Scholar search engines. Analysis. Open access rates were obtained from the Web of Science database, taking into account different types of publications and research areas. Quantitative analyses based on random samplings were used to estimate the potential increase of open access rates achievable with open archiving of post-prints. Results. The open access rate of COVID-19 papers (89.5%) largely outnumbered that of the ten most deadly human diseases (48.8%, on average). We estimated that most of the gap (70%) could be bridged by making available online, post-print manuscripts. Conclusions. The pandemic represents a real breakthrough, in scientific publishing, towards the goal of health information for all, demonstrating that much greater access to medical literature is possible. The green road may be the best way to bring open access rates of peer review of other major diseases closer to that of COVID-19. However, it needs to be implemented more effectively, combining bottom-up and top-down actions and making the open science culture more widespread.
‘In a perfect world doctors and the medical profession would accept people for who they are’: women’s heart health information practices

Introduction. This exploratory study investigates women’s health information practices by examining how women perceive and interpret heart health information from organizations such as Heart & Stroke Canada that are targeted specifically to them. Method. Focus groups were conducted with women (45 – 90 years) with heart disease and without heart disease and three women with heart disease participated in semi-structured interviews. Analysis. The data were analysed using thematic analysis. Five themes that shaped women’s perceptions and interpretations of heart health information were identified: personal expertise and experiential knowledge, consistency in information content, embodied information, ability to act on information, and shame and blame. Results. Women draw from epistemic, social, and corporeal information sources in order to make sense of heart disease. Coupling corporeal and experiential knowledge are important for women to triangulate information. Women’s heart health information practices occur within an androcentric, sociocultural context where broader social information sources that focus on ‘ideal’ health standards must align with women’s lived experiences in order for the information to be acted upon. Conclusions.To craft more effective messages and provide helpful information about heart health, messages and information must align with women’s information practices in ways that acknowledge the intersections and consistency of epistemic, social, and corporeal information sources and the information must be actionable.

Published: June 2022

Introduction. Recommender systems are extensively deployed to provide online users with advisory services, and the design of recommender systems functional features has received substantial attention in academic studies. The social aspects of human–recommender systems interactions, however, have been less explored. Furthermore, measuring user satisfaction, though natural in a business environment, is often challenging for recommender systems research. Thus, it is assumed that the information system success model can be adapted to the system success measurement in recommender systems. Method. This study provides the first empirical test of an adaptation of the information system success model in the context of recommender systems. Additionally, the dual-coding theory argument was introduced to examine the model. Analysis. Based on the proposed model, two presentation types are compared. An experimental design is used and a questionnaire is developed to analysis. Results. The experiment's results show that the recommender system designed on the basis of the dual-coding theory is better than the traditional recommender system on all aspects of the facet. Conclusions. Perceived usefulness and the user satisfaction have a significant positive relationship both with continued intention to use and continued intention to provide.
Differential Effects of Potassium Chloride on Vascular Tissues, Morphological Traits and Germination of Tomato with Sperm Swarm-based Nutrient Optimization
Authors: Concepcion II Ronnie , Janairo Adrian Genevie , Baun Jonah Jahara , Cuello Joel , Dadios Elmer , Vicerra Ryan Rhay , Bandala Argel
Published: June 2022

Potassium chloride (KCl)-induced stress has been predominantly tested on higher crops such as cotton, rice, and wheat. What open agriculture needs now is the extended understanding of possible contributions and detrimental effects of KCl dynamics to tomato as this is one of the major crops consumed worldwide. In this study, the impacts of KCl on the three Philippine tomato (Solanum lycopersicum) genotypes namely, Perlas, Diamante Max F1, and Mica, in separate mesocosms were visualized and measured based on morphological, vascular tissues, and germination variability responses. Three KCl treatments were deployed, which are control (Tc, 0.05 mM), deficit (Td, 0.025 mM), and excess (Te, 0.5 mM), in 3 replicates. KCl-deficit treatment showed improvement in germination rate and vigor index and deteriorated Timson germination index for tomato seedlings. Excess KCl treatment distinctively promotes a higher root (R) to shoot (S) length ratio for Perlas variant with rusty red-orange root color. R/S length increases from control, deficit to excess KCl and R/S fresh and dry weights quadratically increase from control, excess to deficit KCl. The inconsistency of Td and Te treatments to provide equally productive outcomes across the 3 genotypes on the first 37 days after sowing led to the use of 3 bio-inspired algorithms namely, moth-flame, sperm-swarm, and jellyfish swarm optimizers, in determining the most suitable KCl concentration for growth promotion. Multigene symbolic genetic programming was used in constructing the fitness models of five phytomorphological phenotypes namely, root and shoot lengths and weights and leaf count, as functions of KCl concentration and cultivation period. Light microscopy showed that sperm swarm-optimized KCl (0.038 μM) widens the diameter of xylem and phloem vessels in the vegetative stage which is important as they are responsible for transporting nutrients, water, and photosynthesis by-products. Hence, KCl is an essential micronutrient that could alter the growth of crops.

Cytoprotective Effect of Methanol Extract of Laportea aestuans on Acidified Ethanol-induced Gastric Ulcer in Male Wistar Rats
Authors: Tijani Abiola Stephanie , Temitayo Makinde John , Farombi Olatunde Ebenezer
Published: June 2022

Laportea aestuans (Urticaceae) plant is widely distributed in tropical rain forests and used as remedial agent for various diseases in Nigeria by herbal practitioners. Ethanol consumption is one of the common causes of gastric ulcer due to excessive generation of reactive oxygen species and erosion of gastric mucosal layer. This study investigated the cytoprotective effect of pretreatment with methanol extract of Laportea aestuans (MELA) for 7 days on ethanol-induced gastric ulcer in male Wistar rats using cimetidine as a standard drug. Ulcerogenic parameters, oxidative damage, inflammatory and apoptotic markers were evaluated. MELA showed a significant dose-dependent (p < 0.01) decrease in ulcer score (US), ulcer index (UI) and peptic activity with an increase in mucus content and percentage inhibition compared to the ethanol group. Activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), Glutathione S-transferase (GST) and level of reduced glutathione (GSH) were also increased with concomitant decrease in malondialdehyde (MDA) level in MELA treated rats.  Serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β) and activities of cytochrome c (Cyt c), caspases-3 and -9 (CASPS-3 and -9) were also reduced by administration of MELA. Taking together, this study shows that MELA protected the gastric mucosal against the assault induced by ethanol via upregulation of the antioxidant system, and downregulation of inflammatory and apoptotic processes.

HIGHLIGHTS

Oral administration of ethanol to Wistar rats induced gastric ulceration

Oral administration of ethanol to Wistar rats caused ulcer by generation of ROS, inflammation and induce apoptosis

Pretreatment of rats with methanol extract of Laportea aestuans (MELA) preserved the gastric mucosal integrityby boosting antioxidant defence system and inhibiting inflammatory and apoptotic processes

Published: June 2022

The volume of audio visual content produced on social networks has increased tremendously in recent decades, and this information is quickly spread and consumed by a large number of people. The disruption of false news sources and bot accounts for disseminating fake news is a possibility in this scenario. Applied research has been supported by promotional information as well as sensitive stuff over the network. Artificial Intelligence will be used to automatically assess the trustworthiness of social media accounts (AI). In this research, we describe a multilingual strategy to using Deep Learning to solve the bot identification problem on Twitter. End-users can utilise machine learning (ML) methodologies to assess the trustworthiness of a Twitter account. To achieve so, a number of tests were carried out using cutting-edge Multilingual Language Models. Construct an encoding of the user account's text-based features, which is then concatenated with the rest of the metadata to build a potential input vector on top of a Bot-DenseNet Dense Network. As a result, this article evaluates the language constraint from prior experiments where the encoding of the language was limited. Only the metadata information or the metadata information along with some other information was examined by the user account. properties of fundamental semantic text The Bot-DenseNet also generates a low-dimensional representation of the data. Within the Information Retrieval (IR) framework, a user account can be utilised for any application.

A collection of millions of devices with sensors and actuators that are linked via wired or wireless channels for data transmission. Over the last decade, it has grown rapidly, with more than 25 billion devices expected to be connected by 2020. The amount of data released by these devices will multiply many times over in the coming years. In addition to increased volume, the device generates a large amount of data in a variety of modalities with varying data quality defined by its speed in terms of time and position dependency. In such an environment, machine learning algorithms can play an important role in ensuring biotechnology-based security and authorization, as well as anomalous detection to improve usability and security.On the other hand, attackers frequently use learning algorithms to exploit system vulnerabilities. As a result of these considerations, we propose that the security of devices be improved by employing machine learning to detect spam. Spam Detection Using Machine Learning Framework is proposed to attain this goal. Four machine learning models are assessed using multiple metrics and a vast collection of input feature sets in this framework. Each model calculates a spam score based on the input attributes that have been adjusted. This score represents the device's trustworthiness based on a variety of factors. In comparison to other current systems, the findings collected demonstrate the effectiveness of the proposed method.

Bitcoin is a type of Internet currency that is both a digital asset and a payment method. It enables for anonymous payment from one person to another, making it a popular payment mechanism for online illegal activity. Due to its recent price increase, Bitcoin has gotten a lot of attention from the media and the general public. The goal of this research is to discover the Bitcoin price's predictable price direction. Machine learning models are likely to provide us with the information we require to understand the future of cryptocurrency. It won't tell us what will happen in the future, but it might show us the overall trend and direction in which prices are likely to move. The proposed methodology aims to create a machine learning model that uses data to learn about the patterns in the dataset and then uses a machine learning algorithm to forecast the bitcoin price.

Plant disease identification is vital for agriculture because it is essential for enhancing crop yields. Visual plant disease analysis is a novel technique to handle this problem because to recent developments in image processing. There are, however, few works in this field, let alone comprehensive studies. We investigate the challenge of visual plant disease detection for plant disease diagnosis in this research. Plant disease photos, in comparison to other types of photographs, tend to have randomly dispersed lesions, varied symptoms, and complex backgrounds, making discriminative information difficult to capture. We created a new large-scale plant disease dataset containing 271 plant disease categories and 220,592 photos to aid plant disease recognition studies. We approach plant disease recognition using this dataset to emphasise sick portions by reweighting both visual regions and loss to determine the discriminative level of each patch, we first compute the weights of all the divided patches from each image based on the cluster distribution of these patches. Then, during weakly-supervised training, we assign weight to each loss for each patch-label pair to enable discriminative disease component learning. Finally, we use the LSTM network to encode the weighed patch feature sequence into a comprehensive feature representation, extracting patch features from the network trained with loss reweighting. Extensive tests on this and another publicly available datasets show that the proposed strategy is superior. We anticipate that our study will advance the plant disease recognition agenda in the image processing community.

Published: June 2022

This study presents experimentally the combined effect of using Nano-silica, Alccofine, GGBS, and steel fibers on the mechanical properties of hardened concrete. Nano-Silica, Alccofine, and GGBS are used as partial cement replacement by different percentages, and Steel Fiber is used as volume substitution by different percentages. Compressive strength, splitting tensile strength, and flexural strength are evaluated using different combinations between Nano-Silica, Alccofine, and GGBS. Significant improvement in the mechanical properties of concrete is observed on using Nano-Silica due to its high pozzolanic activity. The Optimum content of Steel Fiber is improved splitting tensile strength by 1%t percentage respectively compared to control mix concrete. Utilizing Nano-Silica and GGBS with Steel Fiber leads to improving compressive strength compared to other concrete mixes. Flexural strength is doubled for using Nano-Silica, GGBS, and Steel Fiber compared to other concrete.
