Published: November 2022

Perceived e-learning usefulness as a marketing element has significantly affected student satisfaction, which results in a high propensity to continue using the current e-learning services with their universities. Therefore, this study aims to examine the effects of perceived risk, confirmation, and student motivation on perceived e-learning usefulness. This paper employed a convenience sampling technique to collect opinions from 689 university students at different universities (e.g., Thaksin University, Hatyai University, Prince of Songkla University, and Rajabhat University) around Thailand. Those students were actively using e-learning to access their education. After checking data validity, only 527 valid responses were analyzed through the path analysis method. According to empirical findings, confirmation significantly influenced student motivation, while perceived risk did not significantly impact student motivation. Finally, perceived e-learning usefulness was significantly influenced by confirmation, student motivation, and perceived risk. Furthermore, although these factors significantly influenced perceived e-learning usefulness, attitudes toward perceived e-learning usefulness relied mainly on the degree of confirmation, as this factor highlighted the most substantial effect on perceived e-learning usefulness. Moreover, perceived e-learning usefulness as a marketing element is a promising topic in the e-learning service sector, which requires future studies to examine to which extent the current study findings could apply to other groups of students or practitioners.

Published: November 2022

Haploid technologies are used to create homozygous lines for accelerated breeding. We aimed to optimize the technology for using the isolated microspore culture in vitro to obtain doubled haploids of the carrot (Daucus carota L.).

We studied two carrot varieties with different responsiveness to embryogenesis, Altajskaya lakomka and Breeding line 17. Carrot microspores were isolated from buds and cultivated in liquid nutrient media supplemented with an antibiotic and activated carbon in vitro. They were exposed to different thermal treatments.

The experiment showed the benefits of combining cold pre-treatment of buds (5°C for 1 day) with heat shock of isolated microspores in vitro (32°C for 2 days). The induction of embryogenesis on the NLN-13 medium was twice as high as on the MSm-13 medium. The use of 1% activated carbon in 0.5% agarose increased the yield of embryoids by more than 1.5 times. 100 mg/L of ampicillin was found to be the most efficient concentration. After 30 days of cultivation under optimized conditions, the yield was 161.3 and 44.0 embryoids per Petri dish for the cultivar Altajskaya lakomka and Breeding line 17, respectively.

The induction of carrot embryogenesis is determined by the type and duration of thermal stress, the composition of the nutrient medium, the use of activated carbon as a sorbent, the addition of β-lactam antibiotics, and the type of explant exposed to thermal treatment. Our technology enabled us to obtain homozygous doubled haploid lines of carrots during a year, and these lines were included in the breeding process to create F1 hybrids.
Algerian date palm (Phoenix dactylifera L.) fruit cultivars: HPLC fingerprinting and antibacterial activity
Authors: Ali Haimoud Safia , Allem Rachida
Published: November 2022

The abusive use of antibiotics causes the destruction of intestinal flora and the proliferation of antibiotic-resistant pathogens. Date palm is used in traditional medicine in the Saharan regions due to its biological properties.

The study aimed to identify the phytochemical composition and assess the antibacterial activity of the methanolic extracts of three date cultivars from Algeria. Their total phenolic, flavonoid, and flavonol contents were measured spectrophotometrically. The phytochemical screening was conducted by HPLC fingerprinting using twenty-three pure phenolic compounds as standards. The antibacterial activity against pathogenic bacterial species was assessed using the disk diffusion method.

The colorimetric methods showed that the total phenolic, flavonoid, and flavonol contents ranged from 2.13 ± 0.09 to 2.67 ± 0.02 mg GAE/100 g DW, 1.33 ± 0.21 to 1.55 ± 0.13 mg CEQ/100 g DW, and 0.41 ± 0.23 to 0.47 ± 0.05 mg REQ/100 g DW, respectively. HPLC fingerprinting showed that the extracts of date cultivars served as an excellent source of bioactive compounds (gallic acid, tannic acid, ferulic acid, vanillin, caffeine, quercetin, luteolin, rutin, aspegenin, isorhamnetin, and hesperidin). They also exhibited an antibacterial potential with an inhibition zone diameter ranging from 8.40 to 12.50 mm.

The results clearly demonstrate the antibacterial potency of date palm fruits, which could be attributed to their considerable content of phenolic compounds such as gallic acid, rutin, quercetin, and luteolin.

Authors: Komolafe Oluwatosin
Published: November 2022

Este estudio investigó el efecto de dos prácticas de labranza sobre el rendimiento y el crecimiento del maíz, y propiedades seleccionadas del suelo de un Ultisol del estado de Osun en Nigeria. Esto tuvo como objetivo seleccionar una práctica de labranza adecuada para el crecimiento de los cultivos y el mantenimiento del suelo. El estudio se dividió en dos parcelas experimentales durante la temporada de cultivo temprana y tardía en 2014. La primera parcela se desbrozó manualmente para tener labranza cero, mientras que la segunda parcela se aró dos veces y se rastrilló una vez para labranza convencional. Cada parcela tenía tres bloques (23.0 m x 2.5 m) con un callejón de 1.0 m entre bloques y 1.0 m dentro de las parcelas. Tres semillas del cultivo de prueba se colocaron a una distancia de 75 cm x 50 cm por montículo y cada parcela se desyerbó manualmente a intervalos de dos semanas hasta la cosecha. Las propiedades físicas y químicas del suelo seleccionadas y los parámetros de crecimiento de las plantas se recolectaron y determinaron utilizando el método estándar después de cada temporada de cultivo. Al final del experimento, tuvo los valores más altos de altura de planta y suelo en comparación con la labranza convencional. La labranza cero también tuvo valores químicos del suelo más altos en comparación con la labranza convencional. El rendimiento de grano mostró una diferencia significativa entre las prácticas de labranza. La labranza cero tuvo un mayor rendimiento (1.71 t/ha) en comparación con la labranza convencional (0.97 t/ha). El estudio concluyó que la labranza cero era una mejor alternativa para el crecimiento de los cultivos y el mantenimiento del suelo de un Ultisol.
A Key Comprehensive System for Biobehavioral Surveillance of Populations Disproportionately Affected by HIV (National HIV Behavioral Surveillance): Cross-sectional Survey Study
Authors: Kanny Dafna , Broz Dita , Finlayson Teresa , Lee Kathryn , Sionean Catlainn , Wejnert Cyprian ,   NHBS Study Group
Published: November 2022

Background

The National HIV Behavioral Surveillance (NHBS) is a comprehensive system for biobehavioral surveillance conducted since 2003 in 3 populations disproportionately affected by HIV: gay, bisexual, and other men who have sex with men (MSM); people who inject drugs; and heterosexually active persons at increased risk for HIV infection (HET). This ongoing and systematic collection and analysis of data is needed to identify baseline prevalence of behavioral risk factors and prevention service use, as well as to measure progress toward meeting HIV prevention goals among key populations disproportionately affected by HIV.

Objective

This manuscript provides an overview of NHBS from 2003 to 2019.

Methods

NHBS is conducted in rotating, annual cycles; these 3 annual cycles are considered a round. Venue-based, time-space sampling is used for the MSM population. Respondent-driven sampling is used for people who inject drugs and HET populations. A standardized, anonymous questionnaire collects information on HIV-related behavioral risk factors, HIV testing, and use of prevention services. In each cycle, approximately 500 eligible persons from each participating area are interviewed and offered anonymous HIV testing.

Results

From 2003 to 2019, 168,600 persons were interviewed and 143,570 agreed to HIV testing across 17 to 25 cities in the United States. In the fifth round (2017 to 2019), over 10,000 (10,760-12,284) persons were interviewed each of the 3 population cycles in 23 cities. Of those, most (92%-99%) agreed to HIV testing. Several cities also conducted sexually transmitted infection or hepatitis C testing.

Conclusions

NHBS is critical for monitoring the impact of the Ending the HIV Epidemic in the United States initiative. Data collected from NHBS are key to describe trends in key populations and tailor new prevention activities to ensure high prevention impact. NHBS data provide valuable information for monitoring and evaluating national HIV prevention goals and guiding national and local HIV prevention efforts. Furthermore, NHBS data can be used by public health officials and researchers to identify HIV prevention needs, allocate prevention resources, and develop and improve prevention programs directed to the populations of interest and their communities.

Les fictions défamiliarisantes d’Éric Chauvier
Authors: Gelshorn Julia , Hunkeler Thomas
Published: November 2022

Si la notion de “fiction” hante l’écriture d’Éric Chauvier depuis ses premiers ouvrages, les acceptions changeantes que prend le terme dans ses textes mettent en évidence qu’il ne s’agit pas pour l’anthropologue de marquer ses ouvrages du sceau de la littérarité, mais d’avoir recours à la fiction pour défamiliariser le lecteur et déstabiliser ainsi toute prétention à établir à travers ses enquêtes un savoir stable et objectif.

Chauvier "unheimlich". Du langage à double foyer
Authors: Jaussi Sophie
Published: November 2022

L’oeuvre d’Éric Chauvier met régulièrement en exergue l’anomalie et le sentiment de trouble comme déclencheurs d’une pensée et d’une écriture, qu’elles soient anthropologiques ou littéraires. Suivant cette méthode, le parcours qu’entreprend cet article veut rendre compte d’une inquiétante étrangeté éprouvée au contact des textes de l’auteur, notamment lorsque celui-ci analyse des faits de langage. À travers une mise en parallèle de la notion freudienne d’Unheimliche et de l’expression de « familiarité rompue » utilisée par Chauvier, l’objectif est d’interroger comment se constituent des parentés scientifiques et quelle peut être la productivité épistémologique d’en assouplir les liens traditionnels.

Pousser le curseur. L’enquête fictionnelle chez Éric Chauvier
Authors: Soulet Marc-Henry
Published: November 2022

La conception de l’enquête qu’Éric Chauvier déploie dans son oeuvre, c’est tout au moins l’idée que j’essaie de défendre dans cet article, n’est pas tant située quelque part entre anthropologie et littérature, qu’elle caractérise une forme d’anthropologie qui s’appuie sur la littérature, à la fois comme fiction et comme récit, parce qu’elle est habitée par une recherche continuelle sur la façon d’approcher ce qui échappe constamment à l’énonciation, l’altérité. Éric Chauvier a besoin de mobiliser d’autres méthodes que les formules standardisées et les protocoles de recherche savants en raison de leur impuissance à saisir l’expérience humaine dans sa polyphonie et dans son inconstance, dans sa fragilité et sa précarité aussi quand l’enquête s’attaque à rendre compte de « vies minuscules ».

Versificar em castelhano: "El angelico doctor S. Thomaz de Aquino, su vida, excelencias y muerte" (1626) de Manuel Tomás
Authors: Almeida Mendes Paula
Published: November 2022

O panorama editorial português assitiu, a partir de finais do século XVI, a um muito significativo aumento, no que respeita à publicação de «Vidas» de santos, beatos, veneráveis ou varões e mulheres «ilustres em virtude», obras estas que tinham como objetivos imediatos a glorificação da personagem em questão, a edificação espiritual e a promoção do culto. Ainda que a sua produção não atinja a amplitude da hagiografia e da biografia devota em prosa, as «Vidas» de santos em verso foram também produzidas por alguns autores portugueses, que optaram pelo castelhano enquanto língua para comporem o seu discurso literário: disso é exemplo a obra El angelico doctor S. Thomaz de Aquino, su vida, excellencias y muerte (Lisboa, 1626) de Manuel Tomás. Tendo como pano de fundo esta moldura, este artigo procura chamar a atenção para esta hagiografia em verso, auscultando os prováveis motivos que terão conduzido o autor a optar pelo castelhano, a exaltação da figura de São Tomás de Aquino, através de um registo épico, e os moldes em que se processa a liberdade de composição poética, que ultrapassa a simples transposição de narrativas anteriores para um novo registo.

Characteristics of domestic wastewater in Indonesia generally contain phosphorus 4-15 mg/L. Phosphorus in wastewater must be treated to reduce the phosphorus content according to the Indonesia: Government Regulation No. 82/2001 management of water quality and control over water pollution, maximum allowable levels is 0.2 mg/L. A 1953 report from the Max Planck Institute in Germany by Dr. Kathe Seidal discusses the possibility of using wetland plants to remove nutrients from wastewater. The objectives of this research are to ascertain whether Polonite, Gazobeton, Parepare black volcanic sand beach and Kadidiri coral beach sand can be used as sorbent materials and to obtain the data of phosphorus sorption capacity, efficiency and phosphorus adsorption capacity constant of those materials. This research consists of batch and box experiment. Batch experiment was conducted for all material by mechanically shaking sample for several minutes with varying concentrations of the artificial phosphorus solution prepared from KH2PO4 and wastewater. Box experiment was conducted to evaluate the phosphorus removal by Gazobeton in long term experiment. The highest sorption capacity was attained by polonite 0.917 g/Kg, was followed by gazobeton 0.504 g/Kg, Parepare black volcanic sand beach 0.174 g/Kg and then the finally Kadidiri coral beach sand 0.131 g/Kg. The phosphorus sorption efficiency by Polonite, Gazobeton, Parepare black volcanic sand beach and Kadidiri coral beach sand each Kg are 91%, 50%; 17% and 13% respectively. Phosphorus adsorption capacity constant of polonite is 4906 L/g gazobeton is 115 L/g Parepare black volcanic sand beach is 19 L/g and Kadidiri coral beach sand is 14 L/g
MODELING AND ANALYSIS OF AC-AC SOFT STARTER FOR INDUCTION MOTOR BASED ON THYRISTOR AND IGBT
Authors: Harumwidiah Anisa , Kurniawan Adi
Published: November 2022

Motor Starting on large capacity induction motor using direct on-line starting (DOL) method may cause a problem for system. It is due to motor start-up current that can be up to eight times of the nominal current. Soft starter is an induction motor starting method based on power electronic that can significantly decrease motor starting current, resulting in reduced fuel consumption. In this research, a comparison between DOL starting method and two soft starter methods based on thyristor and Insulated Gate Bipolar Transistor (IGBT) is performed. The results show that thyristor based soft starter method with firing angle 90˚ can reduce input voltage from 220 V to 165 V so that the maximum starting current down from 633 A to 265 A. In the same voltage value, IGBT can reduce maximum starting current to only 100 A

Authors: Fernando Damianus Mario Ricky , Waluyo Joko , Dewayanto Nugroho
Published: November 2022

Gas turbine performance is one of the main concerns in the operating of industrial plants. Thermal efficiency is vital to analyze the performance of the gas turbine. This research purpose is to analyze the gas turbine's thermal efficiency after performed engine replacement in one of the gas industries in Kutai Kartanegara, East Kalimantan, Indonesia. The data was taken during the period from August 2017 to July 2018, while engine replacement was performed in February 2018.  The data were processed to develop simulation models expressing the characteristics of the equipment. The simulation models were then solved simultaneously using the Newton – Raphson Method.  A beneficial advantage of Newton Raphson is that it enables to handle a massive number of data and provides faster iteration compare to other methods.  Based on the simulation results, the thermal efficiency before performed engine replacement was 23.43% with a net power of 18.109 MW and fuel consumption of 1.640 Kg/s. Meanwhile, the development of thermal efficiency after performed engine replacement was 28.24% with a net power of 18.597 MW and fuel consumption of 1.397 Kg/s. This indicates that after performing engine replacement, the thermal efficiency increased by 4.81% and saved fuel by 0.243 Kg/s.

Published: November 2022

Electricity is one of the crucial infrastructures in economic development. The number of registered customers electricity increases every year based on data from the State Electricity Company (PLN) Manokwari branch office data. Electricity increase because it has become an essential part of everyday life. Therefore, in West Papua, it is necessary to fix this electricity problem where the most significant source is still from fossils. By looking at potential sources in West Papua that are more sustainable and renewable to meet public electricity demand in West Papua.In this study, LEAP software will simulate several scenarios, namely based on data from the RUPTL (Electricity Supply Business Plan) and further digging based on the potential literature in West Papua. There will be three scenarios; scenario 1 uses BAU (Business as Usual) as available in RUPTL. Scenario 2 uses BAU data and adds potential renewable energy. Scenario 3 is not using fossil energy but using renewable energy. The result is West Papua can be 100% electrified in 2025 if using scenario 2. The potential for renewable energy in West Papua is wind and sun. However, it does not rule out other sources, such as hydropower.

Authors: Seputri Dyny Wahyu , Fikzia Iffah , Sujiwa Krisna
Published: November 2022

The issues of race, racism and discrimination always become the canter of the study of the African-American community, for example in literature. An example of African-American Literature that described those things is written by Phillis Wheatley. In her poems that were influenced by the Neoclassicism era, entitled: “On being brought from AFRICA to AMERICA'' and “To the Right Honourable William, Earl of Dartmouth”, she delivered the issues of race and racism. This paper aims to analyze racism toward African-America as described in Phillis Wheatley’s poems. The researcher employed a qualitative descriptive method in which the collected data were analyzed, interpreted, and described to answer the objective of the study. The primary data in this undergraduate thesis are two selected poems by Wheatley and the supporting data were taken from books, articles, journals, online sources, and other sources. The researcher applied African-American criticism to answer the objective of the research. The Researchers use three basic tenets of African-American criticism (Everyday Racism, The Social Construction of Race and Voice of color). The findings show Wheatley’s poems portray the life of an African American who experienced racism first-hand. The concept of racism in the two selected poems from Wheatley’s has correlation with 3 concepts of racism of African-American criticism, those are:  Everyday racism, The Social Construction of Race, Voice of color.
The Magic Role of Kim Nam Joon as a Leader of BTS in Conquering the American Market
Authors: Rachmawati Iin
Published: November 2022

Bangtan Sonyeondan or popularly known as BTS is a South Korean phenomenal group. The massive popularity of BTS all over the world cannot be separated from the magic role of their leader, Kim Nam Joon. This research tried to explore Kim Nam Joon’s role in regard to BTS's global popularity. This research used a qualitative descriptive method by using Khan, Nawaz & Khan’s leadership theories and styles as well as used Brown’s audience involvement approach to analyze the data. The result showed that there are four major reasons for Kim Nam Joon’s influence over BTS's success: Kim Nam Joon marked the beginning of BTS, Kim Nam Joon’s compassion and dedication, Kim Nam Joon’s powerful speech, and Kim Nam Joon’s leadership role towards teamwork. Moreover, there was also the fact that several non-BTS American fans tend to become ARMY after they knew about Kim Nam Joon’s leadership role. This is interesting because not all BTS’s fans become ARMY from enjoying BTS songs and performances.
Evaluation of the Influence of the type of Irrigating Solutions in Postoperative Pain and Regression of Perirradicular Injury in Teeth Obtained in Single Session and Single Cone – Clinical Case Study
Authors: Ramos Grazyelly Duarte , Fernandes Kemily Rocha , Ribeiro Willian Alencar , Marques Eduardo Fernandes
Published: November 2022

Endodontic treatment aims at the chemical and mechanical preparation of a dental element that has inflammation or pulp necrosis. During endodontic intervention, postoperative pain may develop, as well as difficulty in the regression of the periradicular lesion. Given the context, the present work is a clinical case report with the objective of evaluating whether the type of irrigating solution used in the endodontic treatment of filled teeth in a single session and single cone influences the postoperative symptomatology and regression of the periradicular lesion. This is a clinical, exploratory, qualitative and descriptive case study, where 2 patients were treated. They were divided into two groups: G1 (n:01) (irrigation with 2.5% sodium hypochlorite) and G2 (n:01) (irrigation with 2% chlorhexidine gel and saline). All dental elements were anesthetized, access surgeries were performed, initial exploration with K file # 10 or 15 was performed until the apparent length of the tooth. Instrumentation technique was performed with hand files and confirmation of working length through Root foraminal locator. Final irrigation was performed with 3 ml of 17% EDTA. The canals were dried with capillary tips, attached to a high-power suction device and with absorbent paper cones and filled, in the same session, by the Tagger Hybrid technique and restored with composite resin. Patients were followed for a period of 24h, 48h, 2, 3 and 6 months for postoperative pain assessment and periradicular lesion regression. Through the results obtained, it was noted that although both irrigating solutions are effective, it was observed that 2.5% sodium hypochlorite caused grade 3 pain according to the patient's pain scale during the first 24 hours, compared with 2% chlorhexidine gel, which had no painful symptoms at any time after completion of treatment and follow-up. In conclusion, in this study, 2.5% sodium hypochlorite may cause more postoperative pain compared to 2% chlorhexidine gel, but there was no significant difference in pain levels between the groups.

Does the Intervertebral Disc Adapt to Load?
Authors: Horschig Dr. Aaron , Lock Dr. Andrew , Williams Dr. Brogan
Published: November 2022

Abstract: Many in the scientific community have been debating the extent to which the spine can adapt. While it is widely accepted that vertebral bones can adapt and become stronger/denser with appropriately dosed loading, there are still many unanswered questions regarding intervertebral discs (IVDs). Recently, some are claiming that IVDs can adapt to stress under load and become stronger and more resilient over time based on the findings from a recent study “Imaging of exercise-induced spinal remodeling in elite rowers” by Frenken et al 2022 in the Journal of Science and Medicine in Sport. The Frenken paper investigates the Glycosaminoglycan (GAG) content of the IVD amongst elite rowers over the course of a training period. They found a temporary increase in this protein and believed that it indicates lumbar disc “remodeling effects” in response to training. This study does show that repetitive loading of the spine does support nutrient transport across the vertebral endplates and an increase in GAG. However, with research showing that a reduction in GAG content is associated with IVD degeneration (a negative adaptation), many have been led to believe the opposite to be accurate; an increase in GAG content means the disc is positively adapting. However, this assumption may be incorrect as it is based on an association, not causation. The proof of nutrient availability isn’t the same as mechanism utility. If in fact, the disc was truly adapting we would likely NOT see an overwhelming amount of research showing an extremely high prevalence of disc degeneration in rowers. The Frenken paper and many more do support the notion that the GAG content alters in response to certain stimuli; however, we can NOT conclude that a temporary increase in GAG content supports the hypothesis that the IVD adapts positively to load.
Stylistic Variation as Manifest in the Informational Style of Intonation (On the Basis of English and Latvian TV Broadcasts)
Authors: Brēde Maija
Published: November 2022

Language variation can be observed on all linguistic levels. Stylistic variation affects not only the segmental but also the suprasegmental level of speech, including intonation, stress, rhythm, tempo and voice timbre. Different speech situations require appropriate intonation styles: systems of interconnected intonational means used in a definite social setting to achieve some particular aim of communication.The article looks into some features of the informational style of intonation in English in contrast to Latvian. For the analysis excerpts of a news broadcast from the Sky News, BBC World and LNT were chosen as presented by professional announcers. Auditive analysis provides data on voice timbre, logical division of speech, style-marking prosodic features and the prominence of semantic centres. The results of the present analysis of the style of intonation in English in comparison with the one undertaken in 1991 reveal that the basic features remain relatively stable. A slight difference in the voice timbre of contemporary announcers has been observed: occasionally it bears traits of emotional colouring. The division of the text basically corresponds to grammatical constructions; the pauses are of variable length. The loudness of speech is normal. The English announcers use a relatively wide voice range. The pace of speech is characterized as moderate with a slow-down on prominent parts of the text. Informational style characteristics of English include also a number of high falls and wide falls that create the impression of emphasis on semantic centres. The basic distinctions of the style in Latvian, in contrast to English, include a generally lower pitch level, a narrower range of high falls, frequent use of mid rises and an occasional high rise that is a feature of colloquial speech. The falling tone in non-final tone units, although less common than in English, is an efficient means of creating emphasis.
The Sequencing of Contrastive Discourse Markers in English
Authors: Fraser Bruce
Published: November 2022

This paper examines an understudied area of pragmatic research, namely, the sequencing of Discourse Markers (DMs). Looking only at the sequencing of Contrastive Discourse Markers (CDMs), thereby excluding both Elaborative and Inferential Discourse Markers, it is shown that only “but” may occur as the first with all of the other CDMs, e.g., “But, on the other hand…,” with “yet” occurring first with a small subset. The rest of the CDMs are relegated to second place in a sequence with the exception of “however.” The sequencing of CDMs adds support to the claim that “but” has more than a single use, the evidence showing both a direct contrast use and a contradiction and elimination use, depending on which CDM it is paired with.
The Effects of Attribution Retraining on Foreign Language Learning
Authors: Michońska-Stadnik Anna
Published: November 2022

This paper elaborates on the role of attribution style in successful foreign language learning. Attribution style, frequently associated with motivation, is considered to belong to individual learner factors. Its type, either external or internal, determines learners’ attitudes to the reasons of their successes or failures. It is believed that appropriate attribution training may contribute to students’ development of more favourable attitudes to their progress (or lack of it) in language learning. The research reported in this paper presents an example of such retraining procedure. One group of 15-year-old secondary school students (36 subjects) underwent the retraining treatment and a significant improvement could be observed both in their perceptions of achievement and their progress in English. The study proved that adolescent learners can profit from attribution training in their perception of success in foreign language learning.
Imaginary Irelands in Ciaran Carson’s sonnet Cycle "The Twelfth Of Never"
Authors: Saliņa Elita
Published: November 2022

Ciaran Carson’s sonnet cycle The Twelfth of Never is remarkable for its dense allusive texture that is not an end in itself but a means of exploring various constructs of Ireland and its history. Viewed as a body of poems, the sonnets create a metaphorical space that erodes the difference between fact and fiction, the colonial and anti-colonial clichés of Irishness and draws the reader into a game with the established literary modes. Therefore the current paper analyses the transformations of the sonnet form and the interplay between the Irish and English poetic traditions in The Twelfth of Never and their implications for the revision of stereotypical concepts essential to the metanarrative of Irish history.

Objective: To evaluate the effectiveness of refined acoustic therapy in
combination with cognitive therapy for tinnitus compared to common
treatment modality. Study Design: A single-center, randomized, and
controlled trial. Methods: Patients were randomised into either the
treatment group (refined sound therapy combined with cognitive therapy)
or the control group (post-auricular injections of lidocaine and
methylprednisolone sodium succinate). Information pre- and
post-treatment was collected using the Self-Rating Depression Scale
(SDS), the Hamilton Anxiety Rating Scale (HAM-A), visual analogue score
(VAS), Tinnitus loudness, and Tinnitus Handicap Inventory (THI) score.
Results: The THI (33.54 versus 19.23), SDS (41.79 versus 35.54) and
HAM-A (9.46 versus 6.19) scores of the treatment group improved
significantly (p<0.05). In the control group, the THI scores
improved significantly (31.7 versus 26.24, p<0.05), but the
SDS (p=0.338) and HAM-A (p=0.574) scores did not. Tinnitus loudness (the
treatment group 46.67 versus 41.19; the control group 43.12 versus
40.18) and VAS scores (the treatment group 5.67 versus 4.17; the control
group 5.58 versus 4.73) were significantly improved in the two groups
(p<0.05). There was significant difference in the reduction of
THI (14.31 versus 5.45), SDS (6.25 versus 1.02), HAM-A (3.27 versus
0.45) and VAS (1.50 versus 0.85) scores between the two groups
(p<0.05), and the treatment group showed a greater reduction.
There was no significant difference in the reduction of tinnitus
loudness (p=0.057). Conclusion: Refined sound therapy combined with
cognitive therapy is more effective at treating tinnitus and improving
psychological symptoms. Post-auricular injections of lidocaine and
methylprednisolone sodium succinate has no effect at improving
psychological symptoms.

Current research tools for pre-clinical drug development such as rodent
models and 2D immortalised monocultures have failed to serve as
effective translational models for human CNS disorders. Recent
advancements in the development of iPSCs and 3D culturing can improve
the in vivo-relevance of pre-clinical models, while generating 3D
cultures though novel bioprinting technologies can offer increased
scalability and replicability. As such, there is a need to develop
platforms that combine iPSC-derived cells with 3D bioprinting to produce
scalable, tunable and biomimetic cultures for preclinical drug discovery
applications. We report a biocompatible PEG-based matrix which
incorporates RGD and YIGSR peptide motifs and full length collagen IV at
a stiffness similar to the human brain (1.5 kPa). Using a
high-throughput commercial bioprinter we report the viable culture and
morphological development of iPSC-derived astrocytes, brain
microvascular endothelial cells, neural progenitors and neurons in our
novel matrix. We also show that this system supports endothelial
vasculogenesis and enhances neural differentiation and spontaneous
activity. This platform forms a foundation for more complex,
multicellular models to facilitate high-throughput translational drug
discovery for CNS disorders.

Background: The effect of prenatal secondhand smoke (SHS) exposure on
childhood atopic dermatitis (AD) remains controversial. We aimed to
investigate the association between prenatal SHS and childhood AD in a
general population-based birth cohort. Methods: Patients included 2,360
mother–child pairs from the Cohort for Childhood Origin of Asthma and
Allergic diseases (COCOA), stratified into 0–3, 4–6, and 7–9 years
age groups. Prenatal SHS exposure was assessed using questionnaires. AD
diagnosis and symptom assessments were conducted through annual visits
by pediatric allergists. Skin prick tests for 18 allergens were
conducted. Serum total IgE and eosinophil levels were measured at birth
and ages 3 and 7 years. Maternal urine cotinine concentrations were
measured at week 36 of gestation. Multivariate logistic regression was
performed. Results: Children aged 7–9 years exposed to prenatal SHS
were significantly more likely to have an AD diagnosis (aOR 1.670, 95%
CI: 0.995–2.804) and current AD (aOR 1.823, 95% CI: 1.051–3.161).
This association in AD diagnosis was stronger in children with
sensitization (aOR 2.205, 95% CI: 1.048–4.642). Higher maternal urine
cotinine levels increased the risk of current AD at ages 4–6 (aOR
2.816, 95% CI: 1.053–7.529). Children exposed to prenatal SHS were
more likely to have a late-onset phenotype of AD (aOR 1.663, 95% CI:
1.038–2.664). Conclusion: SHS exposure during pregnancy was associated
with late childhood AD. Prevention of prenatal SHS exposure is necessary
to reduce the risk of AD in schoolchildren.

Spatial and temporal trajectory analysis of the Crested Ibis (Nipponia Nippon) by fusing multiple sources of data
Authors: Zhou Yulong , Jiang Xian , Chen Zhanlong
Published: November 2022

Aim: Crested Ibis is an endangered animal with extremely high
ecological, humanistic and scientific value. However, there is still a
survival predicament due to increasingly shrinking foraging grounds,
serious interference by human behavior, and increased habitat
requirements. The geographical environment is significant for Crested
Ibis behavior patterns analysis and habitat protection. The spatial and
temporal trajectory contains the habitat location and period
information, a vital record of the Crested Ibis’ habits, and the basis
of all research. Nevertheless, there are only a handful of studies on
the missing trajectory data and fusing multiple sources of environmental
data research methods. Location: Henan Province, Shaanxi Province, China
Methods: The LSTM model was adopted to supplement the missing trajectory
data, and cluster mining was performed. Using Spatial and temporal
trajectory and geographic data, we developed a Random Forest model to
predict the habitat of the Crested Ibis and assessed the habitat
suitability in Luoshan Country. Results: Based on trajectory, we
identified that the Crested Ibis distribution pattern is characterized
by high altitude and proximity to woodland and rivers. And the habitat
dependence on the village implicates human agricultural activities
positively impacting its reproduction. The Random Forest model with high
fitting accuracy (R = 84.9%)is superior, and the
influence factors were gained, finding that 68% of the area is suitable
in Luoshan County. Main conclusions: The trajectory complement model and
the habitat prediction model are developed to obtain the Crested Ibis’
behavioral patterns and habitat distribution. This paper provides a
complete method for analyzing Crested Ibis’ spatial and temporal
trajectory by fusing multi-source data, which is crucial for protecting
the survival and reproduction of Crested Ibis.

Spatial Modeling of land suitability helps in right deployment of a crop
to its suitable locations. The present study was aimed at developing a
GIS and MCDA (multi criteria decision analysis) integrated spatial model
to assess land suitability for oil palm cultivation under rainfed
conditions of India. The most critical parameters (factors) influencing
oil palm cultivation under rainfed conditions were identifiedand weights
were assigned through rank sum method. Spatial data for these parameters
has been collected at district level from standard sources. Thematic
rasters developed in GIS with defined sub-classes. Through MCDA, digital
suitability map developed and suitable areas (three classes) were
delineated, in ArcGIS 10.3.Accordingly, 10.478 million ha (Mha) area was
identified as suitable for rainfed cultivation of oil palm in the
country.Further, to facilitate expansion of oil palm cultivation to
sustainable locations alone, the identified suitable area was restricted
to existing eight land use land cover (LULC) classes only. After
restricting this suitable area to only selected LULC classes, 4.237 Mha
area was identified as suitable in total (0.95 Mha- highly suitable,
1.08 Mha- moderately suitable and 2.21 Mha- marginally suitable). Most
of the highly suitable areas were found in Kerala and Andaman & Nicobar
Islands. This information acts as a decision tool for policy makers in
planning oil palm expansion in the country and presently it is being
followed by Indian government to allocate oil palm crop to most suitable
areas for achieving sustainable production of the crop in the country.
Identification of A Novel Signature for Predicting the Prognosis of Patients with Diquat Poisoning
Authors: Wang Yuhua
Published: November 2022

Diquat (DQ), an effective herbicide, has begun to threaten human health
with the surge in the number of poisonings every year. Here, we present
a powerful signature to improve the prognostic discrimination for
patients with DQ poisoning. In this study, a total of 26 patients with
acute DQ poisoning were enrolled. The median survival time in the death
group was 43 hours. Undoubtedly, plasma concentration (PC), the blood
cells (WBC), neutrophils (NE), aspartate aminotransferase (AST), alanine
aminotransferase (ALT) and serum creatinine (Scr) in the death group
were significantly higher and negatively correlated with survival time.
And COX regression analysis suggested that PC, WBC, NE, ALT and Scr were
the risk factors for poisoning death of DQ poisoning. Furthermore, risk
factors were further developed as a robust signature (PC&Scr) to
predict the prognosis of DQ poisoning. Survival analysis as well as
time-dependent ROC analysis showed powerful predictive ability of
prognostic signature in patients with DQ poisoning. A nomogram
containing risk factors and signature could accurately predict the 2-day
survival probability of individual DQ poisoning. The study shows that
this signature with a powerful ability to predict DQ poisoning outcomes
deserves popularizing in clinical practice.
