Published: February 2022

The aim of the research was to investigate the performance of components of metallurgical wastes in the production of high temperature refractories by self-propagating high-temperature synthesis method. The effect of the filter cake waste amounts and their chemical and physical features on refractories’ mechanical and thermal properties were discussed in this study. A detailed thermochemical assessment of the expected chemical reactions in SHS process based on the waste compositions with binder were carried out. The experiments on the obtaining of carbon containing refractories based on the waste of filter cake were conducted. Thermal conductivity coefficients were determined in the context of the thermal properties of refractory samples via a heat flow meter. In addition, mechanical properties were determined by compression strength.

Published: February 2022

Cardiac bleeding is one of the postoperative complications which gives a negative prognostic implication following a heart surgery. Safety measurements are being taken to resolve cardiac bleeding yet unexpected bleeding is unpredictable. Polymer membranes/scaffolds have been developed to overcome this issue. The utilization of poly (L-lactic acid) (PLLA) as a biodegradable and biocompatible polymer, representing a promising approach to serve as a cardiac membrane in covering cardiac bleeding. In the present work, PLLA membranes were fabricated through a solvent-evaporation casting technique at various concentration of 0.01, 0.03, 0.05 and 0.07 g/mL PLLA. The membranes were observed through an inverted microscope and the tensile properties were determined using a texture analyzer. All membranes were viewed in an approximately general similar structure. The 0.07 g/mL PLLA membrane exhibited Young’s modulus of 1480.89 ± 47.80 kPa, and stiffness of about 20.19 ± 0.65 kPa, which is suitable to be used as a cardiac membrane due to its approaching mechanical properties towards the cardiac membrane at its maximum contraction. In future, the PLLA membrane could be incorporated with other bioactive and therapeutic materials to improve its biological properties for cardiac application.

Published: February 2022

Biodegradable stents (BDS) are projected to be degraded while supporting the blood vessel lumen. Equipping BDS with coated drugs will enhance its biological properties. In this study, everolimus drug was coated on poly (L-lactic acid) (PLLA)/poly (D-lactic acid) (PDLA) scaffolds by utilising polydopamine (PDA) as an intermediate layer. The immobilisation time for the coating process was tailored at 12 and 24 hours. The effects of different immobilisation time of everolimus (12 and 24 hours) were characterised through an ATR-FTIR, SEM and water contact angle analyses to investigate the chemical functionalities, surface morphology and hydrophilicity properties, respectively. The ATR-FTIR results indicated the presence of chemical functionalities of the coating and the scaffolds. The scaffold surfaces were having a transition from smooth to irregular surfaces after the PDA grafting and the coating of everolimus. More homogeneous surface formation was observed and greater hydrophilicity was recorded on the PLLA/PDLA scaffolds coated with everolimus at 24 hours immobilisation compared to the 12 hours immobilisation. These findings are beneficial for the fabrication of BDS with the implementation of everolimus and PDA as coating materials.

Authors: Arreenich P. , Saonanon P. , Aeumjaturapat S. , Snidvongs K. , Chusakul S. , Kanjanaumporn J.
Published: February 2022

Background: At present, there is no consensus for optimal orbital infection management in invasive fungal rhinosinusitis patients. This is the first retrospective cohort study aimed to determine efficacy and side effects of the retrobulbar amphotericin B injection for orbital management in invasive fungal rhinosinusitis patients. Methodology: A retrospective chart review was conducted from 2005 to 2020. Thirty-six patients (forty-two orbits) diagnosed with invasive fungal rhinosinusitis with orbital invasion, treated with or without retrobulbar amphotericin B injection, were included in the study. Results: There were a total of 36 patients in the study, 12 patients received retrobulbar amphotericin B injection and 24 did not. There was no significant difference in orbital exenteration and death between two groups. Visual acuity change at the 3rd month was significantly better in the exposure group. There was a significant difference in the overall clinical outcome at 3rd month and 12th month. There was no report of severe side effects in all patients. Conclusions: Retrobulbar amphotericin B injection showed significant efficacy in stabilizing or even improving visual acuity without any side effects. This procedure should be considered as adjunctive treatment.
Up-date on neuro-immune mechanisms involved in allergic and non-allergic rhinitis
Authors: Van Gerven L. , Boeckxstaens G. , Hellings P.
Published: February 2022

Non-allergic rhinitis (NAR) is a common disorder, which can be defined as chronic nasal inflammation, independent of systemic IgE-mediated mechanisms. Symptoms of NAR patients mimic those of allergic rhinitis (AR) patients. However, AR patients can easily be diagnosed with skin prick test or allergen-specific IgE measurements in the serum, whereas NAR patients form a heterogeneous group and are difficult to diagnose because of an extensive list of different phenotypes, all varying in severity, underlying etiology and type of inflammation. Characterization of those phenotypes, mechanisms and management of NAR represents one of the major unmet needs in the field of allergic and non-allergic diseases. This review aims at providing a comprehensive overview of the state of the art in classifying the NAR patients and focuses on the neuro-immune mechanisms involved in allergic and non-allergic rhinitis, including reflections on the pathophysiology and the currently available treatment options.
The feasibility and safety of percutaneous dilatational tracheostomy without endotracheal guidance in the intensive care unit
Authors: Kim Ji Eun , Lee Dong Hyun
Published: February 2022

Background: Percutaneous dilatational tracheostomy (PDT) is a common procedure in intensive care units (ICUs). Although it is thought to be safe and easily performed at the bedside, PDT usually requires endotracheal guidance, such as bronchoscopy. Here, we assessed the clinical outcomes and safety of PDT conducted without endotracheal guidance.Methods: In the ICU and coronary ICU at a tertiary hospital, PDT was routinely performed without endotracheal guidance by a single medical intensivist using the Griggs technique PDT kit (Portex Percutaneous Tracheostomy Kit). We retrospectively reviewed the electronic medical records of patients who underwent PDT without endotracheal guidance.Results: From January 1 to December 31, 2018, 78 patients underwent PDT without endotracheal guidance in the ICU and coronary ICU. The mean age of these subjects was 71.9±11.5 years, and 29 (37.2%) were female. The mean Acute Physiology And Chronic Health Evaluation (APACHE) II score at 24 hours after admission was 25.9±5.8. Fifty patients (64.1%) were on mechanical ventilation during PDT. Failure of the initial PDT attempt occurred in 4 patients (5.1%). In two of them, PDT was aborted and converted to surgical tracheostomy; in the other two patients, PDT was reattempted after endotracheal reintubation, with success. Minor bleeding at the tracheostomy site requiring gauze changes was observed in five patients (6.4%). There were no airway problems requiring therapeutic interventions or procedure-related sequelae.Conclusions: PDT without endotracheal guidance can be considered safe and feasible.

Artykuł składa się z trzech części. Dwie pierwsze mają charakter historycznoliteracki, mowa w nich o tym, jak twórczość Kapuścińskiego dotarła do Hiszpanii i do Ameryki Łacińskiej, jak była tam odbierana, kiedy i za sprawą jakich czynników reporterowi udało się odnieść sukces, a jego książki zaczęły cieszyć się popularnością. Trzecia część jest natomiast próbą teoretycznego ujęcia zagadnienia. Na podstawie kwerend bibliotecznych i archiwalnych, przeprowadzonych wywiadów oraz korzystając z teorii recepcji Hansa Roberta Jaussa i konceptu „horyzontu oczekiwań”, autorka stara się wyjaśnić, dlaczego dzieła Kapuścińskiego zaistniały właśnie pod tymi szerokościami geograficznymi. Ryszard Kapuściński in Spain and in Latin America The article consists of three parts. First two parts have a historic-literary character as they discuss the following: how the writings of Kapuściński reached Spain and Latin America; how they were received there; when and due to which factors the reporter achieved success and his books started to gain popularity. The third part is a theoretical attempt at conceptualising the issue. Using the enquiries in libraries as well as archives, the conducted interviews and the reception theory of Hans Robert Jauss as well as the concept of the “horizon of expectations”, the author tries to explain why the writings of Kapuściński made a name for themselves in these particular regions of the world.
Wyklęcie Papuszy według Angeliki Kuźniak, czyli biograficzny reportaż jako esej
Authors: Terradas Pau Freixa
Published: February 2022

Poniższy artykuł poświęcony jest literackiemu reportażowi biograficznemu Papusza i obrazowi romskiej poetki, który tworzy jego autorka. Angelika Kuźniak bada losy Papuszy poza mitem utrwalonym w kulturze popularnej, a poszukując Papuszy z krwi i kości, trafia na postać absolutnie tragiczną. Co oczywiste, autorka prezentuje niezwykle krytyczne spojrzenie feministyczne, które wychwytuje grzechy, za które poetka będzie musiała zapłacić, a na ogół są one związane z faktem bycia kobietą. Ale tu nie ma publicystyki, autorka sprawia, że fakty mówią za siebie. Fabuła jest tak skonstruowana, że komentarz moralny jest zbędny. Jest to książka sucha, minimalistyczna, zbudowana na czystych dokumentach i skrawkach życia, pozornie bez obróbki literackiej: jej stylizacja wyraża się w językowej zgrzebności, jakby naśladującej twarde życie Papuszy (życie, w którym szuka się poezji), jej prymitywne pismo, a nawet jej ubogą i naiwną poezję. Jak zobaczymy, w losie Papuszy spotykają się trzy wielkie anatemy: kobiecość, cygańskość i inność. Ale Kuźniak wykracza poza konkretną relację biograficzną, która z kolei służy jako wektor mikrohistoryczny, dzięki któremu uzyskujemy dostęp do wizji historii polskich Romów w XX wieku. W ten sposób Papusza staje się esejem krytycznym dotyczącym dyskryminacji, płci i inności.

Papusza’s Condemnation According to Angelika Kuźniak or the Biographic Reportage as an Essay

The following article deals with the literary biographical reportage Papusza and the author’s impression of the Gypsy poetess. Kuźniak explores Papusza’s life beyond the myth rooted in popular culture. And in her search for the real Papusza she finds an absolutely tragic figure. Naturally, the author applies a highly critical feminist gaze that detects the “sins” for which the poetess will have to “pay”, and in general these are related to the fact that she is a woman. But there is no discourse here: the author makes the facts speak for themselves. The plot is constructed in such a way that the moral commentary is redundant. Kuźniak’s work is a dry, minimalist book, built upon bare factsand scraps of life, with no apparent literary work: its stylisation is expressed through linguistic coarseness, imitating Papusza’s austere way of life (a life where the poetry is sought after), her primitive writing and even her naive poetry. As we shall see, three great condemnations loom over Papusza’s life: femininity, gypsyness and otherness. But Kuźniak goes beyond the specific biographical account, which in turn serves as a micro-historical vector through which we gain access to a vision of the history of Polish Gypsies in the twentieth century. Thanks to that Papusza thus becomes a critical essay dealing with the issues of discrimination, gender and otherness.
Wiara i jej widma. Na marginesie monografii Literatura a religia. Wyzwania epoki świeckiej
Authors: Sosnowska Danuta
Published: February 2022

W artykule przedstawiono dwutomową publikację Literatura a religia. Wyzwania epoki świeckiej (Kraków 2020) jako nowatorską analizę polskiej literatury po roku 1945, w której wykorzystano nowe koncepcje badania religijności i sekularyzmu, przede wszystkim prace Charlesa Taylora. Podkreślono, że zaprezentowane w monografii odczytanie literatury modyfikuje też obraz polskiej kultury, za której cechę charakterystyczną uznaje się religijność. W odwołaniu do ważnych dyskusji i tekstów na temat sekularyzacji w publikacji zastosowano rozszerzone rozumienia religijności, wyjęte z formuły konfesyjnej. Pozwala to na ciekawe odczytania dzieł takich pisarzy, jak Witold Gombrowicz, Miron Białoszewski, Stanisław Lem, Marian Pankowski, wzbogacające paletę polskich postaw wobec wiary. Autorka artykułu zwraca uwagę na dwutomowy podział pracy: tom pierwszy prezentuje metodologie i teoretyczne ujęcia zagadnienia literatury i religii; tom drugi – analizy twórczości konkretnych pisarzy. Dzięki temu czytelnik otrzymuje kompendium sygnalizowanego przez tytuł zagadnienia, które daje mu zarówno przegląd teorii i narzędzi metodologicznych, jak i przykłady czytania na nowo dzieł literatury polskiej.

Faith and Its Phantoms: On the Margin of the Monograph Literature and Religion. Challenges of the Secular Age

The article presents the two-volume publication Literature and Religion. Challenges of the Secular Age (Kraków 2020) as an innovative analysis of the Polish literature after 1945, in which new concepts of researching religiousness and secularity – mostly the works of Charles Taylor – were used. It was highlighted that the literature reading presented in the monograph modifies the image of Polish culture, whose characteristic feature is identified as religiousness. Referring back to important discussions and texts on the topic of secularisation, an extended understanding of religiousness taken out of the confession formula was applied. Such approach enables an interesting reading of works of such authors as Witold Gombrowicz, Miron Białoszewski, Stanisław Lem and Marian Pankowski, which enriches the range of Polish attitudes towards faith. The author of the article notes the work’s division into two volumes: the first volume presents the methodologies and the theoretical approaches to literature and religion; the second volume is dedicated to the analysis of the oeuvres of the specific writers. Thanks to it, the reader receives a compendium on the topic signalised in the title, which provides the overview of theories and methodological tools as well as examples of new readings of Polish literary works.

Lessons Learned from Teaching English through Facebook Live for Future
Authors: Giri Prakash Chandra , Rana Karna
Published: February 2022

Facebook Live has become a means of teaching and learning in many parts of the world. This paper, thus, reports an examination of teaching English through Facebook Live and students’ experiences of learning on it in the COVID-19 pandemic. It as participatory action research employed observation of self-managed Facebook Live streaming, and an online semi-structured interview with students and parents. The intervention of Facebook Live consisted of three strategies: pre-recorded video streaming, live teaching and a combination of both. This paper reports on how students in absence of a physical classroom learned English through Facebook Live, developed communicative skills and gained ICT skills. Although the teacher’s lessons on Facebook Live were appreciated by students and parents as students could get ideas for speaking English, students expressed concerns if they could interact with the teacher and friends. Facebook Live associated with videoconferencing tools, however, can complement physical classroom learning in crises and normal situations.
Nova ocorrência de †Mawsoniidae (Sarcopterygii, Actinistia) na Formação Morro do Chaves, Cretáceo Inferior da bacia de Sergipe-Alagoas, nordeste do Brasil
Authors: Gallo Valéria , Carvalho Marise Sardenberg Salgado de , Santos Hugo Ricardo Secioso
Published: February 2022

The goal of this paper is to describe a new occurrence of †Mawsoniidae in the Morro do Chaves Formation, Sergipe-Alagoas Basin. This stratigraphical unit is represented by an intercalation of coquina and shale beds, deposited in a lacustrine paleoenvironment during the Upper Barremian (Lower Jiquiá local stage). The description is accomplished on the basis of new and more complete material, represented by articulated bones of the palatoquadrate and lower jaw, as well as by gular plate. It was assigned to the genus Mawsonia based on the presence of a stout angular conspicuously ornamented with wrinkles and ridges, as well as palatoquadrate with a single strengthening ridge on its lateral surface. When this new occurrence of Mawsonia was compared with the other genera of Mawsoniidae occurring in Brazil (i.e., Axelrodichthys and Parnaibaia), it was verified that it differs clearly from Axelrodichthys by the inclination of the suspensorium (obliquely oriented in Mawsonia versus vertically oriented in Axelrodichthys). Regarding Parnaibaia, the ornamentation of the angular and gular plate is more delicate in this genus.

Published: February 2022

O presente estudo refere-se ao inventário das samambaias e licófitas do município de Caxias (Maranhão, Brasil), representando um segundo trabalho com estes grupos de plantas no estado. Considerando que são plantas pouco inventariadas no Maranhão, compreendemos ser de importância o estudo da sua composição florística para o conhecimento da diversidade da flora como um todo. O município possui uma área de 531.350 ha e está localizado na parte leste do Maranhão, onde a cobertura vegetal é caracterizada pelo contato do cerrado com a floresta, havendo predomínio do primeiro. Para a coleta do material botânico e registro das informações ecológicas das espécies, foram realizadas excursões bimestrais entre novembro de 2005 a agosto de 2007, nas quais foram registradas 11 famílias, 14 gêneros e 21 espécies. As famílias mais representativas foram Pteridaceae (cinco espécies) e Thelypteridaceae (quatro espécies). Seis espécies foram citadas como novos registros para o Maranhão [Selaginella erythropus (Mart.) Spring, S. flagellata Spring, Acrostichum danaeifolium Langsd. & Fisch., Adiantum serratodentatum Humb. & Bonpl. ex Willd., Lindsaea divaricata Klotzsch e Salvinia auriculata Aubl.]. A maioria das espécies apresentou habitat terrestre, ocorreu no interior das matas ciliares e apresentou distribuição americana.
On a poorly known Amazonian ant-plant association: Myrcia madida McVaugh (Myrtaceae) and Myrcidris epicharis Ward (Hymenoptera: Formicidae: Pseudomyrmecinae)
Authors: Ferreira Leandro Valle , Vasconcelos Heraldo Luis de
Published: February 2022

Ecological data are provided for the first time on the myrmecophilious relationship between the ant Myrcidris epicharis Ward (Hymenoptera: Formicidae: Pseudomyrmecinae) and the Amazonian tree Myrcia madida McVaugh (Myrtaceae), the only Neotropical species of its family to produce domatia in hollow branches. Ants were collected from 30 plants of various sizes (0.9 to 18 m in height) and all plants were inhabited by Myrcidris epicharis Ward. On average, there were 13.3 adult ant workers, 3.8 larvae, 1.5 pupae, and 2.3 eggs per domatium. Ants tend scale insects that live inside the hollow stems. New colonies of M. epicharis are founded by a single queen, and in none of the plants examined more than one queen was found, suggesting that secondary adoption of queens may not take place in this ant species. Myrcidris epicharis Ward appears to provide protection to its host-plant against both vertebrate and invertebrate herbivores.
Notes on the Vertebrates of northern Pará, Brazil: a forgotten part of the Guianan Region, II. Avifauna

Published: February 2022

We carried out seven two-week long avifaunal inventories in five newly-established conservation units spanning the entire ‘Calha Norte’ area, a portion of the Guiana Shield in the northern part of the state of Pará, Brazil, between January 2008 and January 2009. Prior to our study, most of this part of Amazonia was regarded as virtually unsampled from an ornithological perspective. Here, we present an annotated check-list with 446 species of birds recorded during the surveys, including 62 species for which our records represented significant range extensions, and hence are discussed in detail. The number of species recorded at each site varied between 203 and 302, and was positively correlated with the local availability of steep altitudinal and vegetational (forest/savanna and seasonally-flooded/upland forest) gradients. The number of unique species recorded at each site varied between 2 and 27, and reflected an interesting biogeographic pattern in which the Trombetas river appears to separate distinct upland and white-sand forest bird faunas on the Guiana Shield, a pattern also verified for the herpetofauna. Our results also showed that savannas represent a very important component of the local biota, with enclaves harboring a typical bird fauna also distributed in similar habitats in nearby southern Guyana, Suriname, and the state of Amapá in Brazil. Altogether, the five conservation units surveyed harbour 74 bird species of special interest for conservation (threatened, endemic, rare, range-restricted, and hunted species) and therefore play a key role in the preservation of all main subsets of the heterogeneous bird fauna of the Guiana Shield.
Insetos indutores de galhas em florestas de terra firme e em reflorestamentos com espécies nativas na Amazônia Oriental, Pará, Brasil
Authors: Almada Emmanuel Duarte , Fernandes Geraldo Wilson Afonso
Published: February 2022

Neste estudo, apresentamos dados sobre a ocorrência e riqueza de insetos galhadores e suas plantas hospedeiras em florestas de terra firme na Amazônia Oriental, em Porto Trombetas, Pará, Brasil. Nesta região, a Mineração Rio do Norte realiza, desde 1981, um projeto de reflorestamento com espécies nativas em áreas de extração de bauxita. Coletas foram realizadas em 2002, nas estações seca e chuvosa. Foram amostradas 36 áreas de reflorestamentos, com idades de plantio variando de mudas recém-plantadas (menos de 1 ano) até 21 anos, e sete áreas de mata primária. Ao todo, foram encontrados 309 morfotipos de galhas em 255 espécies de plantas pertencentes a 45 famílias botânicas. O grupo de galhadores mais frequente foi os Diptera, da família Cecidomyiidae (97%), sendo também encontrados Coleoptera, Hymenoptera e Lepidoptera. As famílias de plantas com maiores riquezas de espécies de galhadores foram Fabaceae (87), Chrysobalanaceae (12), Burseraceae (18), Annonaceae (15), Clusiaceae (15), Euphorbiaceae (9), Melastomatacaeae (13), Malpighiaceae (17), Apocynaceae (7) e Anacardiaceae (11). Essa diversidade local de galhadores pode ser considerada elevada quando comparada a outros levantamentos realizados no cerrado e na Mata Atlântica.

Published: February 2022

O histórico de uso do solo é fator determinante da sucessão secundária na Amazônia central, levando ao estabelecimento de comunidades de plantas com estrutura, composição florística, biomassa e dinâmica distintas. A utilização do fogo para renovação de pastagens compromete o potencial regenerativo dessas áreas, que, quando abandonadas, são dominadas pelo gênero Vismia e colonizadas por poucas espécies, resultando em florestas secundárias pouco diversificadas nas quais a sucessão permanece estagnada. Uma vegetação mais rica e dominada pelo gênero Cecropia coloniza áreas com histórico de uso menos intensivo, permitindo o rápido desenvolvimento da sucessão. Embasado nos conhecimentos adquiridos ao longo de duas décadas de estudo, discutimos aspectos práticos relacionados ao potencial e aos custos do manejo da sucessão secundária para a restauração dos serviços ambientais e como forma de aliar a geração de renda à redução do desmatamento na região. O manejo do dossel e os plantios de enriquecimento mostraram-se técnica e economicamente viáveis em capoeiras de Cecropia, mas capoeiras dominadas por Vismia requerem o desenvolvimento de propostas de manejo alternativas para sua restauração. Trabalhos em desenvolvimento pelo Projeto Pioneiras, objetivando investigar as trajetórias sucessionais em regiões distintas da Amazônia e analisar os efeitos das mudanças climáticas sobre as florestas secundárias, são apresentados e discutidos no final.
Bitslice Masking and Improved Shuffling:
Authors: Azouaoui Melissa , Bronchain Olivier , Grosso Vincent , Papagiannopoulos Kostas
Published: February 2022

We revisit the popular adage that side-channel countermeasures must be combined to be efficient, and study its application to bitslice masking and shuffling. Our main contributions are twofold. First, we improve this combination: by shuffling the shares of a masked implementation rather than its tuples, we can amplify the impact of the shuffling exponentially in the number of shares, while this impact was independent of the masking security order in previous works. Second, we evaluate the masking and shuffling combination’s performance vs. security tradeoff under sufficient noise conditions: we show that the best approach is to mask first (i.e., fill the registers with as many shares as possible) and shuffle the independent operations that remain. We conclude that with moderate but sufficient noise, the “bitslice masking + shuffling” combination of countermeasures is practically relevant, and its interest increases when randomness is expensive and many independent operations are available for shuffling. When these conditions are not met, masking only is the best option. As additional side results, we improve the best known attack against the shuffling countermeasure from ASIACRYPT 2012. We also recall that algorithmic countermeasures like masking and shuffling, and therefore their combination, cannot be implemented securely without a minimum level of physical noise.
ABE Squared: Accurately Benchmarking Efficiency of Attribute-Based Encryption
Authors: De la Piedra Antonio , Venema Marloes , Alpár Greg
Published: February 2022

Measuring efficiency is difficult. In the last decades, several works have contributed in the quest to successfully determine and compare the efficiency of pairing-based attribute-based encryption (ABE) schemes. However, many of these works are limited: they use little to no optimizations, or use underlying pairingfriendly elliptic curves that do not provide sufficient security anymore. Hence, using these works to benchmark ABE schemes does not yield accurate results. Furthermore, most ABE design papers focus on the efficiency of one important aspect. For instance, a new scheme may aim to have a fast decryption algorithm. Upon realizing this goal, the designer compares the new scheme with existing ones, demonstrating its dominance in this particular aspect. Although this approach is intuitive and might seem fair, the way in which this comparison is done might be biased. For instance, the schemes that are compared with the new scheme may be optimized with respect to another aspect, and appear in the comparison consequently inferior.In this work, we present a framework for accurately benchmarking efficiency of ABE: ABE Squared. In particular, we focus on uncovering the multiple layers of optimization that are relevant to the implementation of ABE schemes. Moreover, we focus on making any comparison fairer by considering the influence of the potential design goals on any optimizations. On the lowest layer, we consider the available optimized arithmetic provided by state-of-the-art cryptographic libraries. On the higher layers, we consider the choice of elliptic curve, the order of the computations, and importantly, the instantiation of the scheme on the chosen curves. Additionally, we show that especially the higher-level optimizations are dependent on the goal of the designer, e.g. optimization of the decryption algorithm. To compare schemes more transparently, we develop this framework, in which ABE schemes can be justifiably optimized and compared by taking into account the possible goals of a designer. To meet these goals, we also introduce manual, heuristic type-conversion techniques where existing techniques fall short. Finally, to illustrate the effectiveness of ABE Squared, we implement several schemes and provide all relevant benchmarks. These show that the design goal influences the optimization approaches, which in turn influence the overall efficiency of the implementations. Importantly, these demonstrate that the schemes also compare differently than existing works previously suggested.
BAT: Small and Fast KEM over NTRU Lattices
Authors: Fouque Pierre-Alain , Kirchner Paul , Pornin Thomas , Yu Yang
Published: February 2022

We present BAT – an IND-CCA secure key encapsulation mechanism (KEM) that is based on NTRU but follows an encryption/decryption paradigm distinct from classical NTRU KEMs. It demonstrates a new approach of decrypting NTRU ciphertext since its introduction 25 years ago. Instead of introducing an artificial masking parameter p to decrypt the ciphertext, we use 2 linear equations in 2 unknowns to recover the message and the error. The encryption process is therefore close to the GGH scheme. However, since the secret key is now a short basis (not a vector), we need to modify the decryption algorithm and we present a new NTRU decoder. Thanks to the improved decoder, our scheme works with a smaller modulus and yields shorter ciphertexts, smaller than RSA-4096 for 128-bit classical security with comparable public-key size and much faster than RSA or even ECC. Meanwhile, the encryption and decryption are still simple and fast in spite of the complicated key generation. Overall, our KEM has more compact parameters than all current lattice-based schemes and a practical efficiency. Moreover, due to the similar key pair structure, BAT can be of special interest in some applications using Falcon signature that is also the most compact signature in the round 3 of the NIST post-quantum cryptography standardization. However, different from Falcon, our KEM does not rely on floating-point arithmetic and can be fully implemented over the integers.

Yagya is one such meaningful gift given by the sages of Indian culture to Sadi Vasudha, which is considered the basis for maintaining the most productive and holistic environmental center.
Rishis say: Ayam yajno vishwasya bhuvanasya nabhih.!
By saying Yagya, Bhuvan has eaten the base point of the creation of this world.
Yogi raj himself says, Shri Krishna.
saha-yajñāḥ prajāḥ sṛiṣhṭvā purovācha prajāpatiḥ!
anena prasaviṣhyadhvam eṣha vo ’stviṣhṭa-kāma-dhuk!!
 In other words: Prajapati Brahma created the subjects and the yajna at the beginning of Kalfa and told them that they might achieve growth through this Yagya. Here the Yagya is going to provide you the desired enjoyment. Yagya is a high level of effort made for charity. Yagya a type of tax: tax: For not giving it to God power like a state. Administration punishes the people. In the same way, the fears come in different forms and create their wrath on the saree world. There is a scientific basis to avoid divine wrath – Yagya. It involves incorporating divinity into the inner world, in the soul of the living being, and by sacrificing the soul of the Apana. The real yajna is to make the samadhi of life home in the form of society. If Satpravarti continues to be included in the feelings, then this is the natural form of Yagya. “Yagyoayam sarvakam dhuk ” Yagya is not the only way to fulfil all desires but the best scientific method of living life is

Factors Influencing Farmers’ Climate Change Adaptation in Northern Ghana: Evidence from Subsistence Farmers in Sissala West, Ghana
Authors:   Wuhan University of Technology, Fagariba Clifford James , Song Shaoxian , Soule Serge
Published: February 2022

Most African countries are vulnerable to climate change as a result of poverty, weather extremes, and insufficient governmental agricultural support. Using the area of Sissala West District, factors influencing farmers’ adaptation to climate change and strategies used to avert climate change impact were determined. A total of 330 small-scale farmers were sampled and their views were determined Using logits regression model, weighted average index, and frequency table. Weighted average index was used to rank opinions of 150 key informants in focus group discussions. Using logits regression model, the study indicated irregular rainfall, high temperature, weather information, and high evaporation as the factors compelling farmers to adapt to climate change. Weighted Average Index used to measure weather extremes revealed that drought and temperature had the highest level of occurrence. Furthermore, climate change adaptation strategies assessed in the study showed that agroforestry practices, drought-resistant crops, and mulching were the most preferred methods. The study concluded that farmers’ ability to adapt to climate change can be improved if Environmental Protection Agency and Ministry of Food and Agriculture intensify climate adaptation campaigns, increase access to weather information, and training farmers on adaptable strategies including, but not limited to, alternative sources of livelihood.
Aplicação de aprendizado de máquina e SIG em estudos de incêndios florestais
Authors:   , Reis Thaynara Lopes dos
Published: February 2022

Os incêndios florestais causam grandes impactos, como desastres ecológicos, diminuição da qualidade da água e perda de vidas humanas e de animais. Entender o comportamento do fogo permite prever as situações de perigo e os impactos dos incêndios. Através de modelos de previsão construídos utilizando redes neurais artificiais (RNA), pode ser possível prever esse comportamento. Para diminuir o perigo de incêndios florestais, é necessário entender as variáveis que mais propiciam o início e propagação do fogo e as áreas mais suscetíveis. Isto é possível a partir da utilização de Sistemas de Informações Geográficas (SIG), onde são criados mapas de suscetibilidade, que avaliam potenciais ocorrências em função de fatores ambientais. Dessa forma, este trabalho foi subdividido em dois capítulos para melhor entender o teor de umidade dos materiais combustíveis, o comportamento do fogo e as variáveis que favorecem a suscetibilidade a incêndios florestais. No primeiro capítulo, configurou-se redes neurais artificiais para previsão da umidade do material combustível de diferentes classes de espessura e do comportamento do fogo em plantios de eucalipto. As variáveis dias sem chuva (Dsch) e umidade relativa do ar (UR) são as que mais contribuem para a umidade do material combustível e a velocidade do vento (VV) e a umidade relativa do ar (UR) são as que mais contribuem para o comportamento do fogo. No segundo capítulo, analisou-se as classes de variáveis ambientais que controlam a ocorrência de incêndios florestais em Coimbra, Portugal, e, a partir delas, confeccionou-se mapas de suscetibilidade a incêndios florestais para a região. As classes que obtiveram maiores porcentagens de áreas queimadas foram: Florestas, >400 m, 0–15º e alto acumulado, para as variáveis uso do solo, proximidades, inclinação do terreno e radiação solar, respectivamente. O SIG se mostrou uma ferramenta eficiente na análise de suscetibilidade a incêndios, pois o modelo escolhido para o mapeamento de suscetibilidade a incêndios na região apresentou maiores somas dos valores das classes “alta” e “altíssima” e menores somas das classes “baixa” e “baixíssima”.

LIQUIDITY RISK AND FINANCIAL PERFORMANCE OF DEPOSIT TAKING SAVINGS AND CREDIT COOPERATIVE SOCIETIES IN KENYA
Authors: Wanjiru Peter , Jagongo Ambrose
Published: February 2022

Purpose: To investigate the effect of liquidity risk on financial performance of DT-SACCOs in Kenya

Materials and Methods: The study will adopt descriptive research design with data comprising of secondary, panel data which will be collected from the 175 DT-SACCOs for the period of five years between the years 2016-2020. Census sampling will be adopted where all the 175 DT-SACCOs will be considered in the analysis. Data will be collected from audited financial statements and other relevant reports submitted by the DT-SACCOs to SASRA.

Results: Financial performance of DT-SACCOs has been unstable and fluctuating over the years as measured by ROA. In 2016, ROA was 2.45 percent which rose to 2.69 percent in 2017. In 2018, it dropped to 2.40 percent before rising to 2.60 percent in 2019 and again rising to 2.65 percent in 2020. One the other hand, liquid assets to total assets ratio has been reducing. In 2016 it was 12.49 percent, 11.85 percent in 2017, 11.77 percent in 2018, and 11.62 in 2019 only to rise to 14.43 in 2020 (SASRA Report, 2020). This reflects the oscillation in liquidity thereby posing liquidity risk. As reflected by the existing empirical literature, there is an inconsistency and consensus on the research findings on whether liquidity risk affects financial performance of DT-SACCOs in Kenya.

Unique contribution to theory, Practice and Policy: Scholars and other researchers interested in the SACCO sub-sector will benefit from the findings of this study. The findings will add to the body of knowledge existing in this field and provide opportunities for further research in this area. Results from the study will be useful to SASRA and other policy-makers in the SACCO sub-sector to strengthen their regulatory framework as well as in development of a more robust liquidity monitoring policy and enhancement of liquidity management practices. The results will be beneficial to SACCO managers and the board members as it will highlight how profitability is affected by liquidity risk thereby developing more robust liquidity monitoring policy as well as enhancement of oversight on liquidity management practices. SACCO members may get an impetus to continuously hold the management accountable on the level of the profitability. This is so because the members stand to benefit most if liquidity risk is low. In addition, it may lead to members’ satisfaction and trust in the societies and hence increased share contribution.
Consumer Payment Behaviour in Australia: Evidence from the 2019 Consumer Payments Survey

Published: February 2022

Since 2007 the Reserve Bank has conducted a Consumer Payments Survey (CPS) every three years, which provides comprehensive information on how Australians make their payments. The 2019 CPS was conducted just before the emergence of COVID-19 in Australia and gives a detailed snapshot of consumer payment behaviour prior to the changes in spending patterns induced by the pandemic. The survey provided further evidence that Australian consumers increasingly prefer to use electronic payment methods rather than cash for their day-to-day payments. Many people now tap their cards (or sometimes phones) even for small purchases. When paying with a card in person or online, consumers are more often choosing to use a debit card rather than a credit card. As a result, debit cards were the most frequently used consumer payment method in the 2019 survey. Consumers are also increasingly taking advantage of the ability to make payments using a range of innovative new payment services that have emerged in recent years, often facilitated by mobile technology and the use of digital payment credentials. Despite the trend towards electronic payments, cash still accounted for a significant share of lower-value payments and a material proportion of the population continue to make many of their payments in cash.
