Authors: He Yuhao , Ren Zijie , Zhu Huimin , Li Mingyang , Zheng Renjun , Song Yuhan , chen zhijie
Published: March 2024

It’s highly challenging to separate feldspar from quartz by flotation owing to their similar crystal structure and physicochemical properties. Using mixed collectors has become a promising method to improve the quartz-feldspar separation. In this study, mixed dodecyl amine (DDA) and sodium petroleum sulfonate (SPS) surfactants were used in the flotation separation of feldspar and quartz, and the adsorption mechanism of mixed collectors and depression mechanisms of two depressants were investigated through zeta potential, contact angle and Fourier transform infrared (FT-IR) spectra. When the pH reached 4.5, the separation of feldspar from quartz was more obvious. In the presence of DDA/SPS collector, the contact angle of feldspar was increased more obviously leading to enhance hydrophobicity. The infrared spectra revealed the interaction of collectors on feldspar surface involved physical and chemical adsorption, whereas the adsorption of collector on quartz was only physical interactions. The use of sodium hexametaphosphate resulted in a significantly enhanced separation performance. The weaker physical adsorption of mixed collector on quartz can be destroyed by sodium hexametaphosphate. This study is beneficial for understanding the collect mechanisms of mixed cationic-anionic surfactants on quartz and feldspar minerals, and promotes the development of advanced feldspar separation techniques.

The cubic power graph of finite group G with identity element e, is an undirected finite, simple graph in which a pair of distinct vertices x, y have an edge iff xy = z3 or yx = z3 for any z ∈ Dn with z3 ≠ e. In this paper, we have studied the structural representation of the cubic power graph of the dihedral group and various structural properties such as clique, girth, vertex degree, chromatic number, independent number, matching number, perfect matching, dominating number, etc. We have also calculated various topological indices such as the Harary index, the first and second Zagreb indices, the Wiener and hyper-Wiener indices, the Schultz index, the harmonic index, the general Randic index, the eccentric connectivity index, the Gutman index, the atomic-bond connectivity index, and the geometricarithmetic index of the cubic power graph of dihedral group Dn when gcd(n, 3) = 1.
OSCILLOGRAPHY OF THE METAMODERN SITUATION
Authors:   Lugansk State Academy of Culture and Arts named after Mikhail Matusovsky, Afanasyeva A.P.
Published: March 2024

Artikel tersebut mengkaji fenomena osilografi sebagai salah satu ciri utama dari situasi metamodern pada tahap perkembangan budaya masyarakat saat ini. Artikel tersebut mencoba untuk menentukan peran dan tempat metamodern dalam sistem "modern-postmodern-metamodern". Tujuan dari penelitian ini adalah karena kebutuhan untuk memahami transisi peradaban ke dimensi budaya yang baru. Pemikiran filosofis merasakan pergeseran sosial dari munculnya paradigma budaya baru, yang menentukan peluang untuk mengkarakterisasi situasi metamodern dan mendefinisikan prinsip osilografi sebagai salah satu penanda utamanya. Artikel tersebut mengungkapkan ciri khas metamodern dari situasi sebelumnya-modern dan postmodern. Menganalisis osilografi sebagai komponen penting dari paradigma baru, penulis berfokus pada fakta bahwa sifat dari situasi yang dijelaskan disamakan dengan osilasi abadi, mirip dengan aksi osiloskop. Metamodern tidak menyiratkan konsep realitas yang pada dasarnya baru, tetapi menghidupkan kembali ide-ide dan estetika modernitas sedemikian rupa sehingga tidak mengesampingkan postmodernisme, tetapi menciptakan sintesis yang harmonis dengannya. Metamodern tidak berusaha meninggalkan ekstrem dari dua arah ini, tetapi mewujudkan elemen tradisi dan inovasi. Osilasi antara cita-cita modernitas dan postmodernitas disebabkan oleh prinsip osilografi yang dibahas dalam artikel tersebut.

Authors:   Samara State Transport University, Denisov D.V.
Published: March 2024

Prediction of scientific, technical and social development requires understanding the structure of the processes being analyzed. The object of the study is 72-year historical cycles. Within the framework of the ontological approach, the 72- year cycle is represented as a set of five processes, each of which lasts 40 years, with the beginning and completion of each subsequent process occurring in each case after 8 years. The subject of the study is the functional certainty of the five distinguished 40-year processes. The hypothesis is formed on the basis of the functional certainty of the elements of the fractal-cluster model: information, technological, environmental, transport, energy. Based on these clusters, ideological, technological, and ethical 40-year processes, a 40-year process of space expansion, and a 40-year energy process are distinguished, respectively. The author analyzes the initial and final eight years of the corresponding 40-year processes. Based on the results of the study, it is concluded that in each case there is a direct connection between the events that mark the beginning and end of the corresponding 40-year process. The analysis is carried out on materials of the Soviet period of national history.
Changes in grassland vegetation on the island of Plavnik (Croatia) over 100 years
Authors: Terzi Massimo , Jasprica Nenad
Published: March 2024

The changes in the grassland vegetation that have occurred over the last almost 100 years on the northeastern Adriatic island of Plavnik (Croatia) were studied. For this purpose, 29 phytosociological relevés of standard plot size were collected using the Braun-Blanquet phytosociological approach and compared with those of 100 years ago. With the aim of defining the differences among the communities and identifying the main environmental gradients, cluster analysis (Ward's method on a Chord distance matrix) and non-metric multidimensional scaling ordination were applied. Taxa score-weighted means of the Ellenberg-type indicator values of main environmental variables were used to assess ecological differences among communities, and disturbance-related indicator values were calculated to assess the disturbance regime in shaping plant communities. According to the syntaxonomic framework for the grassland associations, three associations and two subassociations were found. Among them the Festuco valesiacae-Poetum bulbosae (Poetalia bulbosae, Poetea bulbosae), the Helichrysetum italici salvietosum officinalis (Scorzoneretalia villosae, Festuco-Brometea), and the Hedypnoido rhagadioloidis-Asphodeletum ramosi were proposed as new. The Festuco valesiacae-Poetum bulbosae documents for the first time, based on phytosociological data, the occurrence of the Poetea bulbosae in Croatia. Three associations were considered extinct, possibly as a result of changes in grazing pressure and type.

The algal flora and physio-chemical parameters of seven thermal springs in Denizli were studied for the first time. Samples for algal analyses were taken monthly between May 2013 and June 2014, while the physio-chemical parameters were measured seasonally. The mean pH value of the thermal springs was 6.3, and temperatures varied between 34-60 °C. The significant differences (P < 0.001) among the thermal springs were in their temperature and pH, as well as concentration of Cl^- , Fe^2+ , K^+ , Mg^+ , Na^+ , Li^+ , Ca^+ , HCO3^ - , and SO4^2- ions. A total of 43 Cyanobacteria and three Bacillariophyta taxa were determined.The most common taxon was Spirulina subsalsa Oersted ex Gomont, sampled from five sampling sites. According to the principal component analysis (PCA), the most important determining factor for the algae was temperature, followed by concentration of K^+ and Cl^- ions.
Postural Balance in Football Players with Different Types of Autonomic Regulation When Performing the Romberg Test
Authors:   Belarusian State University of Physical Culture, Tishutin Nikolay A.
Published: March 2024

The study is relevant due to the importance of a high level of postural balance and optimal autonomic regulation in football players’ athletic activity, as well as due to the lack of such comprehensive research. The purpose of the article was to study postural balance maintenance during the Romberg test on a stabilometric platform in football players with different types of autonomic heart rate regulation. Materials and methods. The research involved 100 football players. Based on the cardiointervalograms recorded initially, the participants were divided into groups according to the types of autonomic regulation. Further, centre of pressure fluctuations on the platform were recorded while maintaining a vertical posture with eyes open (54 s) and closed (54 s). Results. Football players with the normotonic and vagotonic types of autonomic regulation are characterized by a higher level of postural balance maintenance in the position with eyes open. In the position with eyes closed, a higher level of postural balance maintenance was found in football players with the vagotonic type of autonomic regulation. The normotonic and vagotonic types of autonomic regulation in football players can be considered optimal for effective posture maintenance under simple conditions, as well as for a normal course of compensatory-adaptive rearrangements in the body and successful adaptation to complicated posture maintenance conditions. The results obtained in this study broaden the current understanding of the postural control system in football players, as well as of the role of the type of autonomic regulation in maintaining postural balance under complicated conditions.

Authors:   The Urals State University of Physical Culture, Oguy Viktor O. , Litvichenko Evgeniy M. , Bykov Evgeniy V.
Published: March 2024

During pregnancy, most women experience a number of health problems, e.g. back pain, anxiety, sleep disorders, headaches, etc. At the same time, it is recommended to treat these conditions with minimal medication. Therefore, non-drug methods, such as massage, and vibroacoustic massage with singing bowls in particular, become relevant. However, an opinion exists that during pregnancy massage should be used with caution, especially in the 1st and 3rd trimesters. The purpose of this article is to analyse the advantages of massage and the specifics of its use in pregnant women, as well as to determine the possibility of applying the author’s method of vibroacoustic massage with singing bowls (patent RU2687006C1) during the prenatal period. In this regard, we analysed the works on the benefits of massage and its use in pregnant women. The ScienceDirect, Cochrane Library, eLIBRARY, and PubMed databases were used to search for the following keywords: massage therapy, pregnant women, classical massage, pregnancy, massage, physical therapy modalities, relaxation, pregnancy massage, antenatal massage. As a result, we came to a number of conclusions: 1) healthy women with uncomplicated pregnancy can have massage throughout the gestation period; 2) massage during pregnancy reduces the symptoms of depression and anxiety, improves sleep, relieves leg and back pain, and has a positive effect on the immune function; 3) during the massage, moderate pressure should be applied; 4) women with complicated pregnancy should get massage only after consulting an obstetrician; 5) vibroacoustic massage with singing bowls improves blood circulation, reduces anxiety, and improves emotional state and sleep quality, which makes it a promising massage method during pregnancy; however, further research is required to determine its effectiveness and safety as well as to adjust the procedure’s protocol in order to use it in pregnant women.

Visual perspective and body ownership modulate vicarious pain and touch: A systematic review
Authors: Lisi Matteo P. , Fusaro Martina , Aglioti Salvatore Maria
Published: March 2024

We conducted a systematic review investigating the influence of visual perspective and body ownership (BO) on vicarious brain resonance and vicarious sensations during the observation of pain and touch. Indeed, the way in which brain reactivity and the phenomenological experience can be modulated by blurring the bodily boundaries of self-other distinction is still unclear. We screened Scopus and WebOfScience, and identified 31 articles, published from 2000 to 2022. Results show that assuming an egocentric perspective enhances vicarious resonance and vicarious sensations. Studies on synaesthetes suggest that vicarious conscious experiences are associated with an increased tendency to embody fake body parts, even in the absence of congruent multisensory stimulation. Moreover, immersive virtual reality studies show that the type of embodied virtual body can affect high-order sensations such as appropriateness, unpleasantness, and erogeneity, associated with the touched body part and the toucher’s social identity. We conclude that perspective plays a key role in the resonance with others' pain and touch, and full-BO over virtual avatars allows investigation of complex aspects of pain and touch perception which would not be possible in reality.

The present work covers novel herbicidal lead structures that contain a 2,3-dihydro[1,3]thiazolo[4,5-b]pyridine scaffold as structural key feature carrying a substituted phenyl side chain. These new compounds show good acyl-ACP thioesterase inhibition in line with strong herbicidal activity against commercially important weeds in broadacre crops, e.g., wheat and corn. The desired substituted 2,3-dihydro[1,3]thiazolo[4,5-b]pyridines were prepared via an optimized BH3-mediated reduction involving tris(pentafluorophenyl)borane as a strong Lewis acid. Remarkably, greenhouse trials showed that some of the target compounds outlined herein display promising control of grass weed species in preemergence application, combined with a dose response window that enables partial selectivity in certain crops.
The Swedish Apparatus of Contract Archaeology and its Entanglement with Society
Authors: Nelson Matthew
Published: March 2024

The Swedish contract archaeology (CA) system has witnessed changes and new goals in the last couple of decades, becoming more steered by the market while new demands have come from Swedish cultural heritage legislation and policies for producing relevant knowledge to society and widening the inclusion of the public. In this paper I examine the Swedish CA system and programs from its three main parties, according to critical heritage studies by Rodney Harrison, especially focusing on the governing tool ‘apparatus’. Criticism, conveyed for instance in a recent survey, has claimed that the apparatus of Swedish CA is unsustainable and inefficient in its present form. This includes deficiencies in the relationships between the parties and with actors and stakeholders outside the system. There is also a democratic discrepancy towards the new heritage goals. I suggest that Harrisons critical view on heritage could be used to argue for changes in the role and boundaries of Swedish CA, taking into accord the conditions of local contexts, interests and needs of communities. An active stance for a more dialogical and inclusive nature of communication could diminish the risk for dissonance, conflict, and negative impacts while creating conditions for positive outcomes and values in society.
India’s Foreign Policy during Prime Minister Atal Bihari Vajpayee
Authors: Verma NMP , Sahoo Rudra Prasad
Published: March 2024

This paper examines Indian foreign policy under Atal Bihari Vajpayee in terms of realistic pluralism. It argues that since the 1998 nuclear test, India has developed a slightly different style of realistic foreign policy as a means to achieve its core interests. It is characterized by an emphasis on engagement with contemporary challenges such as neoliberal globalization, terrorism, the issue of disarmament, coping with the changing international order, the decline of multilateral institutions, and new regionalism, etc. To deal with all these issues, India adopted realistic pluralism to accelerate India's economic development and security interests, as well as enhance its status as an emerging power in the international system by continuously promoting its cherished values. This paper explains how a party with its rightist ideology occupies power at a time when Congress fails to deliver people's aspirations. It analyses the key arguments that have been presented in this framework and the way Bajpayee put them into practice. It concludes with the assessment of Bajpayee strategies and future prospects that it will deliver for Indian foreign policy.
CORPO-VOZO ESCURO COMO EXPERIÊNCIA PARA UMA IMERSÃO EM VOZ: O ESCURO COMO EXPERIÊNCIA PARA UMA IMERSÃO EM VOZ
Authors: Rocha Valeria Cristina Machado
Published: March 2024

A voz carrega a trajetória do sujeito (como da personagem) que fala, sua maneira única de pertencer ao mundo. O atual panorama teatral brasileiro sofre constantes mudanças e influências e exige do ator uma adequação em seu treinamento corpóreo-vocal. Mas qual seria, então, esse treinamento? O presente artigo traz excertos de experiências realizadas com estudantes de Artes Cênicas da Faculdade de Artes Dulcina de Moraes (FADM), em Brasília-DF. Realizou-se um treinamento vocal com os estudantes vendados, com o intuito de desenvolver um conjunto de procedimentos práticos a partir dos demais sentidos. Durante os experimentos, constataram-se frágeis a compreensão e a assimilação da união corpo-voz durante o fazer teatral. No entanto, com o desenvolvimento e a apropriação da rotina de ensaios, o grupo superou sua insegurança com a escuridão e passou a criar de maneira espontânea e autônoma, evidenciando que a experiência e o saber provindo do corpo proporcionam autoconhecimento, que por sua vez potencializa o fazer teatral e a voz em cena.

Utilizar o método dos elementos finitos para conhecer a resposta dinâmica e consequentemente determinar as frequências naturais e modos de vibração, evitando assim a construção de protótipos físicos de chassis, gerando economia de tempo e dinheiro. A Carruagem da Alegria, um equipamento construído na Faculdade de Engenharia de Ilha Solteira destinado ao passeio de pessoas idosas e com deficiência física, apresentava o projeto de seu chassi escasso de informações a respeito de seu comportamento dinâmico. Diante disto, no presente trabalho utilizou-se a análise dinâmica pelo Método dos Elementos Finitos a favor de enrobustecer o projeto do chassi em relação ao conhecimento dinâmico. Pelo software comercial Ansys, a estrutura foi simulada e obteve-se que o chassi sofre o fenômeno da ressonância em duas situações, ou seja, quando o equipamento é carregado com um passageiro em sua parte dianteira e um na parte traseira e também quando carregado com dois passageiros na parte dianteira e um na traseira. Posto isso, um estudo investigativo acerca de modificações estruturais e alteração no material de construção do chassi foi realizado, simulando diversas opções de chassi e executando uma análise comparativa entre os valores de frequências naturais obtidos e a faixa da frequência de excitação mapeável incidente no equipamento. Foram obtidas opções de chassi melhores a serem empregadas no equipamento, uma vez que foi possível sair de um chassi tido como indesejado e não recomendado para o projeto da Carruagem da Alegria e por fim chegar em opções mais adequadas, as quais não sofrem com o fenômeno da ressonância.

Este artículo presenta un análisis histórico y socioespacial centrado en el papel de Francisco Morales Bermúdez en la fase crepuscular del militarismo peruano hacia el final del siglo XX, destacando su influencia en la adopción y ejecución de doctrinas geopolíticas. El objetivo principal es examinar detenidamente el impacto de Morales Bermúdez, destacando cómo su gestión fue modelada por doctrinas geopolíticas. La investigación revela cómo las políticas de Morales Bermúdez, aunque inicialmente continuaron algunas iniciativas de su predecesor Velasco, eventualmente se orientaron hacia la liberalización económica y un acercamiento a Estados Unidos, incluyendo la participación en la Operación Cóndor. Este cambio estratégico tuvo profundas implicaciones tanto en la política interna como en la posición de Perú en América Latina, reflejando las complejidades y desafíos de gobernar durante un periodo de intensas dinámicas geopolíticas globales. El análisis contribuye a una comprensión más matizada de la historia política peruana y su interacción con la geopolítica regional, enfatizando el impacto de las decisiones de liderazgo en la dirección nacional y su inserción en el contexto latinoamericano.

The vast majority of decision-making approaches used for long-term planning of municipal solid waste management systems (LPMSWMS) are ground on scenario-based structures. However, the scenario-based structures may overlook many real-world possibilities because of their restricted mass balances. This study is the first attempt to review the current state of optimization models, which are used as a decision-making approach for LPMSWMS, by focusing on the mass balances. In line with this purpose, 146 peer-reviewed articles were examined based on a new literature evaluation scheme. According to the findings, it can be stated that a significant majority of the articles offer non-deterministic optimization models dealing with the uncertain nature of the LPMSWMS problems. Considering all optimization models examined in the study, most of the model formulations have linear mathematical forms in terms of objective and constraint functions. However, it is quite interesting that none of the models produced solutions for a management system alternative with an integrated (non-restricted) mass balance. Accordingly, it is very questionable whether the results obtained from the current models have the power to give the most suitable solution for an up-to-date management system. As a result of the review, it is highly recommended that the optimization models to be conducted for the LPMSWMS in the future should search for new mathematical approaches considering the integrated mass balances under certainty and/or uncertainty.

This qualitative research study investigated critical contemporary issues faced by first-year students at a University of Technology in South Africa. Drawing from interviews with five participants, the study illuminated three major challenges: academic pressures during the transition, financial constraints, and technology integration. The findings revealed that adapting to new pedagogical methods and academic expectations causes stress and a sense of inadequacy. Financial burdens stemming from tuition fees and living expenses hinder engagement while technology’s integration presents both opportunities and challenges, accentuating the need for digital literacy education. The study underscored the importance of comprehensive orientation programs, financial aid initiatives, digital literacy training, and peer mentoring to address these issues. Recommendations also encompass flexible learning pathways, holistic well-being support, and collaborative spaces. By recognizing and proactively addressing these challenges, higher education institutions can facilitate smoother transitions, foster inclusive environments, and ultimately enhance the overall first-year student experience. This research contributes valuable insights to guide policy development and support mechanisms, ensuring the academic success and holistic well-being of first-year students in the dynamic landscape of higher education.

Published: March 2024

This paper adapted the framework of rhetorical devices developed by Michalik-Suchanek to examine the language used in social media posts of Ghanaian celebrities, focusing specifically on the use of rhetorical elements. Instagram and Twitter were chosen as the primary platforms for analysis due to their popularity among Ghanaians. The dataset consisted of posts from 15 Ghanaian celebrities, sourced from either one or both platforms. The study adopted the embedded mixed-methods approach. A total of 130 celebrity posts from Instagram and 70 from Twitter, all from April 2022, were collected using mobile phones and laptops through an observational guide. Through a critical analysis of the sampled data, 22 rhetorical devices were identified, with syntactic devices being the most commonly used. The study revealed that most Ghanaian celebrities prefer to use Standard English in their posts. It was also revealed that these rhetorical devices were employed by celebrities to establish unique relationships with their followers, persuade them to take action, express intentions, caption videos and pictures, and enhance the overall meaning of their posts. The research showed that the use of rhetorical devices was effective in enriching the language of the posts. Based on these findings, it was recommended that further studies be conducted to explore the use of rhetorical elements in social media posts of politicians, businesspeople, entertainers, and other public figures in Ghana. Such studies would contribute to a deeper understanding of how rhetorical strategies are employed in the digital communication landscape. This study contributes to existing knowledge on social media research conducted in Ghana.

Blazars are a subject of intense debate, specifically regarding their jet launch and emission mechanisms, and the origins of their γ-ray radiation. To explore these issues, we have built a comprehensive sample of flat-spectrum radio quasars (FSRQs), with well-characterized spectral energy distribution. This study aims to elucidate the dominant jet launch mechanism and the main processes behind the inverse Compton (IC) component. Additionally, we seek to pinpoint the location of the γ-ray dissipation region relative to the central black hole, denoted as R

γ
. Our approach involves a detailed analysis of broad-line region (BLR) emission, from which we derive robust estimates of the black hole masses using two distinct virial techniques. This enables us to constrain the jet power across a wide array of FSRQs. Our findings lead to several significant conclusions: (i) The correlation of jet power with black hole mass allows us to test the Blandford–Znajek, Blandford–Payne, and hybrid mechanisms. We find that the hybrid mechanism is most effective in explaining the jet power observed in the majority of FSRQs; (ii) The IC component of the γ-rays in FSRQs is predominantly due to the external Compton process. (iii) Through simulations, we determine the minimum and maximum values of R

γ
(the γ-ray dissipation region) and conclude it is located outside the BLR. This conclusion is derived from the variability timescale analysis.

FRB 20220610A is a high-redshift fast radio burst (FRB) that has not been observed to repeat. Here, we present rest-frame UV and optical Hubble Space Telescope observations of the field of FRB 20220610A. The imaging reveals seven extended sources, one of which we identify as the most likely host galaxy with a spectroscopic redshift of z = 1.017. We spectroscopically confirm three additional sources to be at the same redshift and identify the system as a compact galaxy group with possible signs of interaction among group members. We determine the host of FRB 20220610A to be a star-forming galaxy with a stellar mass of ≈109.7
M
⊙, mass-weighted age of ≈2.6 Gyr, and star formation rate (integrated over the last 100 Myr) of ≈1.7 M
⊙ yr−1. These host properties are commensurate with the star-forming field galaxy population at z ∼ 1 and trace their properties analogously to the population of low-z FRB hosts. Based on estimates of the total stellar mass of the galaxy group, we calculate a fiducial contribution to the observed dispersion measure from the intragroup medium of ≈90–182 pc cm−3 (rest frame). This leaves a significant excess of

pc cm−3 (in the observer frame); further observation will be required to determine the origin of this excess. Given the low occurrence rates of galaxies in compact groups, the discovery of an FRB in one demonstrates a rare, novel environment in which FRBs can occur. As such groups may represent ongoing or future mergers that can trigger star formation, this supports a young stellar progenitor relative to star formation.
Integrated taxonomy, biology and biogeography of the Afrotropical genus Xyloctonus (Coleoptera, Curculionidae, Scolytinae)
Authors: Jordal Bjarte H.
Published: March 2024

The peculiar Afrotropical bark beetle genus Xyloctonus Eichhoff, 1872 is revised and its biology described. Several unusual morphological features reflect adaptations to predator avoidance as they are highly exposed during mating externally on tree trunks and branches. Observations invariably indicate that males and females abandon the nest under bark at an early stage of progeny, the males already before eggs hatch, potentially engaging in subsequent additional matings. Most species have a clear preference for host plants in the plant family Sapotaceae. Although the genus is broadly distributed in forested parts of Africa, Madagascar and Mauritius, most species are found in the eastern part of this range. A Bayesian biogeographical analysis revealed a possible origin of the genus in Madagascar in the early Eocene, with subsequent colonisation of the southern African region in late Eocene. This contrasts with the closely-related xyloctonine genus Ctonoxylon Hagedorn, 1910, which is of western Congolian ancestry and more recently reached Madagascar multiple times during late Miocene. Two new species are described: Xyloctonus magnussp. nov. from Madagascar and X. genierisp. nov. from Burkina Faso. Synonyms are proposed for X. subcostatus Eggers, 1939 (= X. striatus Eggers, 1939) and X. scolytoides Eichhoff, 1872 (= X. latus Eggers, 1922). Identification to species is provided in a key illustrated with photographs of most species.
Two novel species of arctic-alpine lichen-forming fungi (Ascomycota, Megasporaceae) from the Deosai Plains, Pakistan

Published: March 2024

Members of the lichen-forming fungal genus Oxneriaria are known to occur in cold polar and high altitudinal environments. Two new species, Oxneriaria crittendenii and O. deosaiensis, are now described from the high altitude Deosai Plains, Pakistan, based on phenotypic, multigene phylogenetic and chemical evidence. Phenotypically, O. crittendenii is characterised by orbicular light-brown thalli 1.5–5 cm across, spot tests (K, C, KC) negative, apothecia pruinose, hymenium initially blue then dark orange in response to Lugol’s solution. Oxneriaria deosaiensis is characterised by irregular areolate grey thalli 1.5–2 cm across, K test (light brown), KC test (dark brown), apothecia epruinose, hymenium initially blue then dark blue in response to Lugol’s solution. Both species share the same characters of thalli with black margins and polarilocular ascospores. The closest previously reported species, O. pruinosa, differs from O. crittendenii and O. deosaiensis in having non-lobate margins, thin thalline exciple (45–80 μm thick), short asci (55–80 × 25–42 μm) and K positive (yellow) and KC negative tests and divergent DNA sequence in the ITS, LSU and mtSSU regions. The newly-described Oxneriaria species add to growing evidence of the Deosai Plains as a region of important arctic-alpine biodiversity.

We have read with interest the paper by Ridley et al1on the radiographic damage discordance between the sacroiliac joints (SIJs) and the spine in patients with ankylosing spondylitis (AS) from the Prospective Study of Outcomes in AS (PSOAS) cohort, which includes patients from the United States and Australia. Their results have encouraged us to investigate the prevalence of severe SIJ disease without evidence of concomitant syndesmophytes in the spine in our patient cohort from Spain.
