A fractional-order model of COVID-19 with a strong Allee effect considering the fear effect spread by social networks to the community and the existence of the silent spreaders during the pandemic stage
Authors: Yousef Ali
Published: March 2022

End of 2019, the world has experienced a virus known as COVID-19, which almost changed everything in our daily and social lives. Every day, experts in medicine, economics, finance, and many different fields inform the community through the media or social networks about the virus, the effects, and changes in our "new life". The virus is highly transmittable and shows different mutated forms. Therefore, to describe this attractive event, many mathematical models and studies have been applied to work on the infections and transmission risks of COVID-19. However, another discussion in the community besides the virus's transmission effect isthe fear of getting infected and dying from the corona. People who have never heard about this virus before 2019 face uncertain and different information about the virus from the media, social networks, and health organizations. This paper proposes a mathematical model of FDEs with a strong Allee effect about the novel coronavirus COVID-19, including the community's fear effect spread through the media and different networks. The primary target is to emphasize the psychological pressure during and after the lockdown. Using the Routh-Hurwitz Criteria, we analyze the local stability of two critical points: disease-free and co-existing. In the end, we use MATLAB 2019 to implement simulation studies that support the theoretical findings.

Published: March 2022

According to the actual situation of gun-launched UAV intercepting "Low-slow-small" target and the specific maneuverability of gun-launched UAV, an enhanced real proportion guidance law (RTPN) guidance interception method is designed. The traditional RTPN method does not consider the saturation overload limit and the capture region of arbitrary maneuvering target. In addition, aiming at the measurement error and the dynamic response delay of the gun-launched UAV during the interception, the EKF data fusion track prediction algorithm is proposed. Simulation results show that the proposed method can effectively solve the problem.
Stability analysis of microscopic models for traffic flow with lane changing
Authors: Piu Matteo , Puppo Gabriella
Published: March 2022

This paper investigates the mathematical modeling and the stability of multi-lane traffic in the microscopic scale, studying a model based on two interaction terms. To do this we propose simple lane changing conditions and we study the stability of the steady states starting from the model in the one-lane case and extending the results to the generic multi-lane case with the careful design of the lane changing rules. We compare the results with numerical tests, that confirm the predictions of the linear stability analysis and also show that the model is able to reproduce stop & go waves, a typical feature of congested traffic.

Authors: Sánchez-Roldán Z. , Zamorano M. , Martín-Morales M.
Published: March 2022

The environmental problems associated with the construction sector have promoted the worldwide scientific community to pay attention to the use of recycled aggregates from construction and demolition waste. SciMAT and VOSviewer bibliometric tools have been applied in order to analyse, quantify and visualise the conceptual and social aspects of this scientific field, as well as its evolution between 1973 and 2019. The study of 843 scientific papers in this field has shown that the most important thematic area has been Recycling. In general, the common objective of the published papers was to study the efficient use of resources contained in construction and demolition waste due to their treatment to produce recycled aggregates, particularly for use in concrete. Likewise, some lacks have been observed in other areas of the analysed field, e.g. the use recycled aggregates in applications subject to less demanding regulations (mortars, precast concrete products, or green roofs).
Investigating the Potential of Integrating Augmented Reality into the 6E Instructional 3D Geometry Model in Fostering Students’ 3D Geometric Thinking Processes
Authors: Sudirman  , Kusumah Yaya S. , Martadiputra Bambang Avip Priatna
Published: March 2022

Schools as a source of knowledge need to facilitate the 3D geometric thinking process involving a series of cognitive action. Therefore, this research investigates the potential of integrating augmented reality (AR) into the 6E instructional 3D geometric model (6E I3DGM). This is an exploratory research carried out with a teacher and 28 junior high school students in Indramayu District, Indonesia. The data were collected through observations and interviews and examined, selected, extracted, and coded based on the criteria determined. The data collected were further interpreted and concluded, and descriptively analyzed using content analysis. The result showed that learning that integrates AR into 6E I3DGM has the ability to raise 3D geometric thinking processes in the dimensions of representation, spatial structuring, and measurement. This is because the use of AR can characteristically help students represent, construct nets, visualize the structure of 3D shapes, and assist in measuring the surface area and volume of 3D geometry. Moreover, it also facilitates students in constructing knowledge through a series of 3D geometric thinking activities. Therefore, the use of learning that integrates AR into 6E I3DGM has the potential to be an alternative for learning 3D geometry both during and after the COVID-19 pandemic.

This research was conducted to increase the productivity of farmers and to plan the planting of crops by farmers when using a hydroponics system that controls various environmental conditions, in which plant growth factors such as temperature, humidity, water temperature, pH and electrical conductivity are important factors for hydroponics. The Internet of Things control and notifications enabling farmers to quickly modify and improve their crop treatment. This research focuses on use of the Internet of Things to control plant growth factors. Displays and alerts are communicated to the user through a web application where, when comparing plants with controlled growth factors and unregulated systems, it can be seen controlled plant growth factors are in the desired range of the plant, whereas in uncontrolled systems there are unwanted values range of plant, which can cause the plant to not fully grow or even to wither. In this system, farmers are able to view plant growth factor data and can retrospectively view graphs displayed on the web application by this controlled system when the measuring sensors in the system are in range that plants do not want. It prompts farmers to manage the system, which allows them to fix the system quickly and with minimal damage to crops.
Selection of A Suitable Algorithm for the Implementation of Rate-Limiter Based on Bucket4j
Authors: Bartkov Maxim Vitalievich , Borovikov Dmitry
Published: March 2022

In shared network services, rate limiting is essential as it controls the requests of the users or requesters in a specific amount of time. Due to rate limiting, the service or API stays protected from overuse, malicious attack, DDoS attack, data traffic spikes, etc. Bucket4j is a java library that has been demonstrated to be effective in rate limiting. While Bucket4j is mainly based on token bucket algorithm, rate limiting processes can be based on various effective algorithms. Selecting the most suitable algorithm for rate limiting is an essential problem. To address it, we have done a detailed analysis of rate-limiting algorithms based on various factors. The factors we have considered are easy implementation, proper handling of data traffic, data starvation, memory usage, etc. We have found out that for different set of requirements, different algorithms are  preferable.
Enhanced Multilevel Fuzzy Inference System for Risk Adaptive Hybrid RFID Access Control System
Authors: Suleiman Dima , Al-Zewairi Malek , Shaout Adnan Shaout
Published: March 2022

Risk-based access control systems are part of identity management systems used to accommodate environments with needs for dynamic access control decisions. The risk value is subjected to overestimation or underestimation since it is measured qualitatively, thus; causing uncertainty problems, which was apparent in a previously proposed hybrid risk adaptive (HRA) access control system. Conversely, Fuzzy Inference Systems can deal with the uncertainty of measures and control the outcomes more precisely; therefore, a multilevel fuzzy inference system (HRA-MFIS) was proposed to replace the risk assessment model in HRA. This paper continues to improve the previous model by introducing an enhanced multilevel fuzzy inference system (EHRA-MFIS), which utilizes user behaviour and time analysis to detect anomalous access behaviour. Moreover, it improves the hybrid adaptive risk calculation module by adding authentication, classification and the degree of user anomalous behaviour to the risk calculation algorithm. The results show that the proposed model has smoothed out the transition between the different risk levels and enhanced the system's overall security by considering the failed authorization attempts and failed authentication attempts, asset classification, and user behaviour when calculating the risk level.
La notion de technè en Grèce ancienne
Authors: Warin Isabelle
Published: March 2022

Dans l’Antiquité, la technè est une notion clé de la culture grecque qui recouvre une infinie variété des formes de savoir, comme la poésie, la rhétorique, la métallurgie, la menuiserie, la médecine ou bien les mathématiques. La compréhension de cette notion doit faire face d’une part à l’ambiguïté de la pensée grecque à l’égard de ceux qui maîtrisent une technè et de l’autre aux présupposés et les préjugés de la pensée moderne qui associe technè et perspective technique. Dans cette contribution, nous tenterons de comprendre l’enracinement de la technè et des détenteurs de technai dans la société grecque antique.
Technique, Technics, Technik, substantifs : les mots à travers les dictionnaires du xixe siècle
Authors: Camolezi Marcos
Published: March 2022

Cet article est proposé comme une contribution à l’historiographie intellectuelle du concept de « technique ». Se confirmant au moyen d’une analyse vaste des entrées consacrées au substantif « technique » et à ses cognats dans les dictionnaires des langues française, anglaise et allemande parus au xixe siècle, l’hypothèse centrale du texte consiste en l’idée suivant laquelle l’association entre technè et « technique » ne s’est pas transmise d’une façon continue au cours de l’histoire. Plutôt, cette association est une invention relativement récente. En tenant compte d’une règle tacite qui normalisait l’emploi des adjectifs (technique, technical, technisch) et défendait l’usage des substantifs (technique, technics, Technik) au crépuscule du xviiie siècle, nous soutenons que la reconnaissance lexicographique des substantifs a été liée à l’intérêt historiographique et philosophique grandissant qui a été porté sur ces termes.
Lucien Febvre lu par Maurice Daumas :comment écrire une histoire des techniques au xxe siècle
Authors: Tesnière Valérie
Published: March 2022

Deux registres d’action se croisent sans se recouper complètement dans la pensée de Maurice Daumas, directeur scientifique et auteur de l’Histoire générale des techniques, parue aux Presses universitaires de France de 1962 à 1979, déjà auteur d’une Histoire de la science parue chez Gallimard, dans l’Encyclopédie de la Pléiade, en 1957. D’une part, le fait que, pour Daumas, l’invention technique « est le résultat d’une expérience collective sans cesse accumulée », ce qui explique la simultanéité des inventions. Ce constat pourrait être mis en parallèle avec L’apparition du livre, publié par Lucien Febvre et Henri-Jean Martin en 1958. D’autre part, les conditions de production d’une histoire des techniques sont indissociables d’une collaboration entre différents types de contributeurs, comme le montre le numéro spécial « Les techniques, l’histoire et la vie » publié dans les Annales d’histoire économique et sociale en 1935. L’article interroge les renvois entre ces différentes publications et les concepts à l’œuvre sur la technique entre 1935 et 1979, sans oublier le fait que Febvre et Daumas sont également des entrepreneurs d’édition scientifique, pour qui la réflexion sur la technique ne se dissocie pas d’une certaine expérience pratique.

L’article dont nous présentons la traduction est une étude complète sur la création et le développement entre les deux guerres mondiales d’un établissement remarquable à plus d’un titre : le Lycée technique de Wilno, métropole régionale alors rattachée à la Pologne. Aujourd’hui Vilnius est capitale de la Lituanie, mais sous les Tsars, Vilna était cosmopolite avec de fortes minorités : juive, polonaise et biélorusse. Fort d’une dizaine de paragraphes, ce compte-rendu publié en 1937 dans le périodique new-yorkais di Tsukunft (L’Avenir) semble être fait pour inviter les immigrés aux États-Unis à soutenir les institutions pionnières du vieux continent. Il est écrit au moment de l’exposition universelle de Paris à laquelle une délégation du réseau scolaire yidiche de Pologne vint défendre ses récentes réalisations. En 1937, Gerszon Pludermacher, l’auteur du présent article, fut l’un des délégués à la Conférence internationale sur l’Instruction primaire et c’est Rose Simkhovitsh qui y lut le rapport sur l’école primaire laïque en yidiche. Tout fut reporté dans les Actes de la conférence.

Authors: Alam Samsul , Kashem Md. Abul
Published: March 2022

Understanding how human resource information system (HRIS) is linked with competitive strategies (CSs) has become an important research topic in the field of strategic human resource management (SHRM) and information systems (IS). This study intends to find a relationship between HRIS and CSs and the resulting competitive advantages gained from the relationship that impact the organization's overall performance. A semi-structured questionnaire survey based on the face-to-face interview method was conducted among human resource (HR) executives of the selected Bangladeshi business organizations to collect data and find results. The result shows that HRIS implementation has a significant influence on CSs. Again, HRIS contributes to leveraging benefits from these strategies. The statistical findings reveal that HRIS pay-off (36%) is positively correlated (37%) with CSs to a lower-medium extent, but this correlation insignificantly affects business performance in this horizon. Finally, a framework is developed showing how to leverage HRIS pay-off based on findings and literature.

Published: March 2022

The surge in self-service technologies (SSTs) adoption in the banking industries across the globe has changed customers' banking experiences. Customers have developed a passion for SSTs which has affects their intentions to save with a bank. The positive effects of employing SSTs in the banking industries are evident in literature however, little is known on how SSTs affect customer experiences in the banking industries of developing countries like Ghana. The study involved a sample of 384 banking customers in Ghana. The study confirms the positive effects of SSTs adoption on customer experiences. The study establishes that customers' adoption of SSTs is influenced by their perception of SSTs usefulness and ease of use which increases their satisfaction level. The study finds out that when SSTs are deployed individually, they have no effect on customer experiences in the banking sector. However, when the individual SSTs are combined in usage, they collectively produce a positive effect on customer banking experience.

Published: March 2022

The research on underwater wireless sensor networks (UWSNs) has grown considerably in recent years where the main focus remains to develop a reliable communication protocol to overcome its challenges between various underwater sensing devices. The main purpose of UWSNs is to provide a low cost and an unmanned data collection system for a range of applications such as offshore exploration, pollution monitoring, oil and gas pipeline monitoring, surveillance, etc. One of the common types of UWSNs is linear sensor network (LSN), which speciall targets monitoring the underwater oil and gas pipelines. Under this application, in most of the previously proposed works, networks are deployed without considering the heterogeneity and capacity of the various sensor nodes. This negligence leads to the problem of inefficient data delivery from the sensor nodes deployed on the pipeline to the surface sinks. In addition, the existing path planning algorithms do not consider the network coverage of heterogeneous sensor nodes.

Authors: Jungst Martijn
Published: March 2022

The new digital age introduces a continuous stream of technological innovations. Yet, little is known about how these technological innovations influence workplace behavior. Drawing on the stressor-strain model, this study examined the possibility that emotional exhaustion would explain the effect of technological insecurity on individual performance. This study further posited that leader-member exchange would interact with technological insecurity to influence emotional exhaustion and, through it, individual performance. This study found that technological insecurity negatively associates with individual performance. Results also indicated that emotional exhaustion carries the negative consequences of technological insecurity. This study further found that the effects of technological insecurity attenuate at high levels of leader-member exchange. Finally, this study discussed implications for theory and practices as well as offered future research directions.

Published: March 2022

AZD1222 (Covishield) COVID-19 vaccination response among healthy adults and chronic renal disease patients has been compared in this analysis. Compared to healthy individuals, vaccine induced immune response seems to be suboptimal after two doses of the vaccine in patients with chronic renal disease on hemodialysis. Infection following full course of vaccination can boost the vaccine induced antibody levels in both healthy individuals and patients with chronic renal disease.
It is necessary to conduct comprehensive prospective research to further evaluate these conclusions made based on this preliminary data evaluation, and to find out its overall impact for future SARS-CoV-2 infection and its disease outcome.

Published: March 2022

After a two-year pandemic, coronavirus disease 2019 (COVID-19) is still a serious public health problem and economic stability worldwide, particularly in the Association of Southeast Asian Nations (ASEAN) countries. The objective of this study was to identify the wave periods, provide an accurate space-time forecast of COVID-19 disease and its relationship to vaccination rates. We combined a hierarchical Bayesian pure spatiotemporal model and locally weighted scatterplot smoothing techniques to identify the wave periods and to provide weekly COVID-19 forecasts for the period 15 December 2021 to 5 January 2022 and to identify the relationship between the COVID-19 risk and the vaccination rate. We discovered that each ASIAN country had a unique COVID-19 time wave and duration. Additionally, we discovered that the number of COVID-19 cases was quite low and that no weekly hotspots were identified during the study period. The vaccination rate showed a nonlinear relationship with the COVID-19 risk, with a different temporal pattern for each ASEAN country. We reached the conclusion that vaccination, in comparison to other interventions, has a large influence over a longer time span.

Published: March 2022

Foot ulceration is one of the biggest complications experienced by type 2 diabetes patients. The severity and prevention of new wounds can be overcome through early detection interventions. This systematic review aims to explain and provide a comparison of various interventions that have been developed to prevent the occurrence of Diabetes Foot Ulcers (DFU). We searched Scopus, Science Direct, PubMed, CINAHL, SAGE, and ProQuest for English, experimental studies, published between 2016-2021 that tested early detection for preventing diabetic foot ulcers in diabetic patients. The Joanna Briggs Institute guidelines were used to assess eligibility, and PRISMA quality and a checklist to guide this review. 25 studies were obtained that matched the specified inclusion criteria. The entire article has an experimental study design. Majority of respondents were type 2 diabetes patients who have not experienced ulceration. Based on the results of the review, there were 3 main types of interventions used in the early detection of DFU. The types of intervention used are 1) conventional intervention/physical assessment, 2) 3D thermal camera assessment system, and 3) DFU screening instrument. The three types of interventions have advantages and disadvantages, so their use needs to be adjusted to the conditions and needs of the patient. the development of DFU risk early detection intervention needs to be developed. Integration with modern technology can also be done to increase the accuracy of the results and the ease of examination procedures.
Abnormal Responses in Cognitive Impulsivity Circuits Are Associated with Glycosylated Hemoglobin Trajectories in Type 1 Diabetes Mellitus and Impaired Metabolic Control
Authors: Jorge Helena , Duarte Isabel C. , Paiva Sandra , Relvas Ana Paula , Castelo-Branco Miguel
Published: March 2022

Background: Risky health decisions and impulse control profiles may impact on metabolic control in type 1 diabetes mellitus (T1DM). We hypothesize that the neural correlates of cognitive impulsivity and decision-making in T1DM relate to metabolic control trajectories.Methods: We combined functional magnetic resonance imaging (fMRI), measures of metabolic trajectories (glycosylated hemoglobin [HbA1c] over multiple time points) and behavioral assessment using a cognitive impulsivity paradigm, the Balloon Analogue Risk Task (BART), in 50 participants (25 T1DM and 25 controls).Results: Behavioral results showed that T1DM participants followed a rigid conservative risk strategy along the iterative game. Imaging group comparisons showed that patients showed larger activation of reward related, limbic regions (nucleus accumbens, amygdala) and insula (interoceptive saliency network) in initial game stages. Upon game completion differences emerged in relation to error monitoring (anterior cingulate cortex [ACC]) and inhibitory control (inferior frontal gyrus). Importantly, activity in the saliency network (ACC and insula), which monitors interoceptive states, was related with metabolic trajectories, which was also found for limbic/reward networks. Parietal and posterior cingulate regions activated both in controls and patients with adaptive decision-making, and positively associated with metabolic trajectories.Conclusion: We found triple converging evidence when comparing metabolic trajectories, patients versus controls or risk averse (non-learners) versus patients who learned by trial and error. Dopaminergic reward and saliency (interoceptive and error monitoring) circuits show a tight link with impaired metabolic trajectories and cognitive impulsivity in T1DM. Activity in parietal and posterior cingulate are associated with adaptive trajectories. This link between reward-saliency-inhibition circuits suggests novel strategies for patient management.

Assessment of Cochlear Function in Children with Sickle Cell Anemia
Authors: Jibril Yasir Nuhu , Shamsu Khadija Ahmad , Adamu Auwal , Abdullahi Hamisu , Kolo Emmanuel Sara , Ahmed Sagir Gumel
Published: March 2022

Background:

Sickle cell disease is characterized by vaso-occlusion which leads to impaired blood supply to several organs. The cochlear in particular has been known to be highly sensitive to anoxia which is, in turn, a proven cause of sensorineural hearing loss (SNHL). Early detection of hearing loss is paramount in these patients, as the cochlear ischemic damage is repetitive and progressive. Once the damage is sufficiently enough to cause noticeable hearing loss, the loss is mostly substantial and irreversible. Otoacoustic emission is useful in detecting early cochlear damage.

Materials and Methods:

Children with sickle cell anemia (SCA) (HbSS) aged between 1 and 12 years diagnosed by hemoglobin electrophoresis and equal number of controls matched (HbAA) matched for age and sex were recruited for the study. All participants underwent a detailed ear, nose, and throat examination and tympanometry. Those with normal middle ear function were further subjected to transient-evoked otoacoustic emissions (TEOAEs) testing.

Results:

There were 60 patients with SCA (cases) and 60 controls. The age of the participants ranged between 1–12 years with a mean of 6.5 ± 3.74 among the cases and 7.02 ± 3.54 among the controls. The male–female ratio was 0.9:1. Among participants with normal middle ear function, TEOAE was abnormal in 43 (48.8%) ears of the cases and 70 (73.7%) ears of the controls. There was a statistically significant difference in abnormal TEOAEs outcome between cases and the control group (P = 0.002).

Conclusion:

Children with SCA had a high rate of abnormal cochlear function. Therefore, there is a need for periodic monitoring of cochlear function in these patients so as to detect and treat SNHL early.

Authors: Meshref Mostafa , Masoud Ahmed Taher , Benmelouka Amira Yasmine
Published: March 2022

Cerebral venous sinus occlusion is an exceptional presentation in the emergency department. Otitis and mastoiditis are rarely associated with cerebral venous sinus occlusion. It is considered as a redoubtable complication with potentially severe outcomes. Symptoms that may indicate this thrombosis are variable and include progressive headache, intracranial hypertension, seizures, focal neurological deficits, and ophthalmologic symptoms. In this article, we report a case of a young female patient presenting with otitis and mastoiditis complicated with intracranial thrombosis. She was successfully treated with antibiotics, anticoagulants, and analgesics. Furthermore, we provide a brief review on cerebral venous sinus thrombosis with a focus on its risk factors and its management. Finally, we emphasize the need for better awareness about this potential intracranial complication.
Indian Association of Paediatric Anaesthesiologists advisory for paediatric airway management
Authors: Goyal Shilpa , Sharma Ankur , Bhatia Pradeep , Sen Indu Mohini , Nath Gita , Varghese Elsa
Published: March 2022

The pediatric airway poses a challenge particularly for those who do not anesthetize small children on a regular basis. Anatomical and physiological variations of the airway at different ages have an impact on the decision of which medication to administer with regard to route, dosage, and duration of action as well as the choice of equipment. Knowledge of this helps in the routine management of airway in children. Technological advancements and research have rendered numerous pediatric airway devices available for securing the airway in elective and emergency scenarios. However, their availability alone does not solve all problems. Having the knowledge, the ability to promptly recognize difficulty and to know when to call for help early are key factors for a favorable outcome. This advisory is formulated as a guide for a successful and safe airway management in children for the anesthesiologist involved in the care of pediatric patients.
Media and the Constitution of the Political: South Asia and Beyond
Authors: Vasudevan Ravi
Published: March 2022

This volume features the writings of leading media scholars from South Asia and Europe on the topic of how media articulates political energies and transformational logics. The research traverses the press, newsreels, entertainment cinema, photography, television, music, social media and data-driven politics. The authors consider how media industries, institutions and practices constitute sites where conflicts relating to wider social change are observable. Authors address media materiality and aesthetics in tracking political effects and resonances on subjects such as wire photo transfers, film set design, the formal structures of the newsreel, the role of television audience surveys, the relationship between digital and paper records, the place of media in courts of law and the phenomenon of the media trial. The overall approach in understanding media and the political is not only to access formal institutions, both of media and politics but also to expand perspective to trace the wider dispersed appearance of the political in and through media.
History of investigations of fossil algae in Croatia
Authors:   Croatian Geological Survey, Zagreb, Croatia, Grgasović Tonći
Published: March 2022

Investigations of fossil algae in Croatia began in 1907 with the very first description of the Permian dasyclad Mizzia velebitana from Mt. Velebit by Austrian geologist Richard Schubert. This was followed by Julius Pia’s investigations (1920, 1925), on material given to him by Schubert. The first Croatian researcher on fossil algae was Milan Herak, Pia’s PhD student, with his first paper on Ladinian dasyclads published in 1950. He cooperated with a colleague from the Faculty of Science, Vanda Kochansky-Devidé, who published her first papers together with Herak on Permian and Carboniferous dasyclads in 1959 and 1960. While Herak focused on Triassic algae, Kochansky-Devidé investigated mostly Upper Palaeozoic algae and fusulinid foraminifera. Ivan Guši? comes from the same faculty, and his first paper was published in 1966. Mom?ilo Milanovi?, from the Institute of Geology (the present day Croatian Geological Survey), published his first paper in 1962, focusing mainly on Permian algae. The most prolific researcher Branko Soka? also came from the Institute of Geology; his first papers dated from 1964, and he is still an active researcher. Over time, papers originating from the “Zagreb Algological School” become distinguished by rich and well illustrated fossil material, making numerous contributions to the better understanding of fossil benthic algae from younger Palaeozoic and Mesozoic strata. This was possible not only because of the diligence of the authors, but was also the result of the very thick and well exposed carbonate sequence of the Croatian Dinarides Mts. Rajka Radoi?i? from Beograd (Serbia) also described some taxa from Croatia. Almost all the research refers to dasycladal algae, while other algae are only rarely investigated. Complete references to all papers are given.
The hunt for Cummingsella (Carboniferous, Chlorophyta)
Authors: Mamet Bernard , Préat Alain ,   Université libre de Bruxelles, Département des Sciences de la Terre et de l’Environnement
Published: March 2022

Until recently Cummingsella was only known by two rare and puzzling species, erected on very limited material. The genus was therefore considered as representing a very uncommon and puzzling form that played no role in carbonate sedimentation. Recent studies of Viséan carbonates in the American Midcontinent have disclosed a prolific Cummingsella flora that indicates the proximity of an algal bank. Cummingsella can therefore be considered locally abundant, cosmopolitan (Europe, Australia, North America), ranging in age from the Tournaisian to the Namurian (Serpukhovian).

Two reef-building red algae of the family Solenoporaceae – Solenopora rectangulata n. sp. and Parachaetetes dizluensis n. sp. – are described from a ?Norian-Rhaetian section of the Nayband Formation exposed south of the town of Bagherabad, northeast of Esfahan, central Iran. These algae build reef structures or patches up to 17 m thick, either on their own or in association with other reef-building organisms including sponges, corals, etc. Such solenoporacean reef structures have not been described before, either from Iran or elsewhere in the world. Morphologically, both algae are easily distinguished by the different sizes of their thalli and particularly by their branching pattern.
Petrascula iberica (DRAGASTAN & TRAPPE), Tersella genotii BARATTOLO & BIGOZZI, and the relationships of club-shaped dasycladalean algae during Late Triassic-Early Jurassic times

New observations on abundant material from the type locality of Petrascula iberica (DRAGASTAN & TRAPPE) GRANIER et al. 2003, reveal the presence of a reproductive structure (ampulla) located on the inner-middle part of each primary lateral. This fact suggests a new interpretation of the alga and the establishment of a new genus: Granieria BARATTOLO & ROMANO, n. gen. Also, the taxonomic status of the other club-shaped specimens from both the High and Middle Atlas of Morocco and the Central Apennines of Italy is reviewed.
Calcareous algae, foraminifera and sequence stratigraphy of the Fahliyan Formation at Kuh-e-Surmeh (Zagros Basin, SW of Iran)
Authors:   Exploration Directorate of National Iranian Oil Company (NIOC), Abolfazl Hosseini Seyed , Conrad Marc A.
Published: March 2022

Palaeontological, environmental and sequence stratigraphic studies were carried out on the shallow carbonate platform facies of the Berriasian – Hauterivian, Fahliyan Formation and the lower part of the Gadvan Formation, at Kuh-e-Surmeh. The studies were based on calcareous green algae (mainly Dasycladales) and accompanying benthic foraminifera, focusing on revision of the considerable, pioneering work of GOLLESTANEH (1965, 1979), initially undertaken on behalf of the National Iranian Oil Company (NIOC). Thirty two species of calcareous green algae and thirty four species of benthic foraminifera were identified from the Fahliyan Formation and from the lower part of the Gadvan Formation. A number of the recognized calcareous green algae were previously given different names by other authors working in SW Iran. Additional taxa were also recorded for the first time in the Zagros basin, including Clypeina dragastani, C. estevezii, C. solkani, C. parasolkani, Holosporella arabica, Otternstella lemmensis, Salpingoporella circassa, S. istriana and S. katzeri. Salpingoporella circassa is quite common and apparently recorded for the first time from Southern Tethys. Also Salpingoporella ? inopinata n. sp., (originally named Iranella inopinata by GOLLESTANEH, a nomen nudum) appears to be quite common in the Fahliyan Formation, although apparently endemic to SW Iran. Three main depositional environments were recognized based on the faunal/floral association, lithological and sedimentological characteristics: inner ramp/restricted platform, mid ramp/margin to open platform, and outer ramp/platform slope, with water depths ranging from about 5m to 20m, rarely reaching 40m. Facies changes facilitated the recognition of three large scale sequences throughout the studied succession, bringing interesting relationships with the sequence bundles identified in the Arabian Plate.
On some Salpingoporella species from the Lower Cretaceous of Dinaric karst
Authors:   Croatian Geological Survey, Zagreb, Croatia, Sokač Branko , Grgasović Tonći ,   Croatian Geological Survey, Zagreb, Croatia
Published: March 2022

In this paper a new species Salpingoporella tari n.sp. is established, found in a sample of Barremian intraclastic grainstone. It is similar to S. annulata (LORENZ) and S. grudii (RADOIČIĆ), but visibly more robust. It has few branches per whorl, and the whorls being spaced far apart. The branches are laterally compressed at their distal ends, therefore being vertically elongated. New finding of Salpingoporella cemi (RADOI?I?) gave the new data on the variability of the shape of its branches, and on the precise stratigraphic position of the investigated localities. Besides, Salpingoporella patruliusi BUCUR is illustrated, this being its first find outside Monti Apuseni (south Carpathians) and its geographic range thus encompassing also the Dinarides. Also, a large observed number of specimens of Salpingoporella muehlbergii (LORENZ) with ramified thallus makes that feature both its species-specific and generic characteristic. Quite strongly varying values of various biometric parameters, depending on the position on the thallus in one and the same specimen, raises serious questions as to their reliability and usefulness as a distinguishing factor in comparing both the specimens of one and the same species and of species of the same genus.
Praktykowanie narodu. Palestyńska praktyka doświadczenia narodowego do czasu powstania Palestyńskiej Autonomii Narodowej
Authors: Pycińska Magdalena
Published: March 2022

Chociaż napisano już wiele opracowań poświęconych tak zwanej kwestii palestyńskiej, Magdalena Pycińska znalazła przestrzeń do badań, które dotychczas były rzadko podejmowane, zwłaszcza w polskim piśmiennictwie naukowym. Niniejsza publikacja wykracza poza dominujący w analizach konfliktów bliskowschodnich paradygmat oparty na ujęciu politologicznym. Jest w istocie interdyscyplinarna w pozytywnym tego słowa znaczeniu, a podjęta próba zbadania procesów kształtowania nowoczesnej tożsamości narodowej wśród Palestyńczyków zasługuje na uznanie. Autorka wykorzystała wiele źródeł, które umożliwiły ukazanie procesu powstawania palestyńskiej tożsamości narodowej w konsekwencji przemian politycznych, społecznych, kulturowo-religijnych czy gospodarczych. Sięgnęła do wspomnień, pamiętników, literatury, dokumentów prawnych i politycznych, a także opracowań o charakterze analitycznym. To wszystko sprawia, że książka Praktykowanie narodu łączy w sobie badania z zakresu socjologii, nauk o kulturze, religioznawstwa oraz nauk o polityce. Pojawiają się również elementy psychologii (przemiany świadomości społecznej), nauk prawnych (choćby kwestia obywatelstwa w Mandacie Palestyny) czy ekonomicznych. dr hab.

The Temple Road Towards a Great India. Birla Mandirs as a Strategy for Reconstructing Nation and Tradition
Authors: Kudelska Marta , Kamińska-Jones Dorota , Staszczyk Agnieszka , Świerzowska Agata
Published: March 2022

This book presents an analysis of the foundations organised by the Birla family in India. Several generations were involved in the renovation and establishment of sanctuaries, temples and other sacral buildings. As a result, between 1933 and 1998, nineteen Birla Mandirs were established, mainly in northern and central India. All the temples have the capacity to surprise with their various decorative motifs, not seen in other places, which – apart from their aesthetic function – above all bear important symbolic content. Therefore, is it possible to treat the Birla Mandirs as a specific medium – the carrier of a particular message that is not only religious, but with a significance that permeates other layers of social and political discourse. This message, as the authors of the book claim, have a bearing on the socio-political thought of India – supported by the creation and propagation of ideas related to identity and a national art. It also conveys the idea of hierarchical Hindu inclusivism which, although considering all religions as equal, treats Hinduism in a unique way – seeing within it the most perfect form of religion, giving man the opportunity to learn the highest truth. The book also examines whether the temples founded by the Birla family and the religious activities undertaken therein apply the concept of “inventing” tradition, and whether traditions created (or “modernised”) in contemporary times are a way of enhancing the appeal of the message conveyed from temple to society.
