Bright sunshine duration (BSD) data are required for simulating biomes using process-based vegetation models. However, monthly global paleoclimate datasets that can be used in paleo data–model comparisons do not necessarily contain BSD or radiation data. Considering the theoretical and practical aspects, the scheme of Yin, X. (1999) is here recommended to estimate monthly time series of relative BSD using only monthly climate and location data. As a case study for the Carpathian Region, the efficiency of both the original and a variant of that scheme is analysed in this paper. The alternative scheme has high applicability in paleoenvironmental studies. Comparison of the estimated and observed BSD data shows that from May to August, the value of relative root mean squared error in more than 90 percent of the study area does not exceed the threshold of 20 percent, indicating an excellent performance of the original estimation scheme. It is also found that though the magnitude of overestimation for the alternative algorithm is significant in the winter period, the proposed method performs similarly well in the growing season as the original. Furthermore, concerning modelling the distribution of biomes, simulation experiments are performed to assess the effects of modifying some configuration settings: (a) the generation of relative BSD data, and (b) the algorithm used to create quasi-daily weather data from the monthly values. Under both the recent humidity conditions of the study region and the spatial resolution of the climate dataset used, the results can be considered sufficiently robust, regardless of the configuration settings tested. Thus, using monthly temperature and precipitation climatologies, the spatial distribution of biomes can be properly simulated with the configuration settings proposed here.

A number of climatic cycles and teleconnections are known on the Earth. By definition, the cycles can have a periodic effect on the global climate, while teleconnections can influence the weather at large distances. At the same time, it is overwhelmingly assumed that the hydrological cycle is permanently intensifying all over the world. In this study, we determine and quantify some connections among these climatic cycles and precipitation data from across Hungary. By using cross-correlation and cross-spectral analysis, the connections of the climatic patterns and oscillations with the precipitation of different Hungarian areas have been defined. We used the 1950–2010 timeframe in order to be able to detect effects of several climatic patterns, such as the El Niño-Southern Oscillation (ENSO), the Arctic Oscillation (AO), the North Atlantic Oscillation (NAO), the Pacific/North American teleconnection pattern (PNA) and the Atlantic Multidecadal Oscillation (AMO) on the rainfall events of the Carpathian Basin. Data from four different precipitation measurement sites and oscillation indexes from several databases were used. The results help to understand the patterns and regularities of the precipitation, which is the major source of natural groundwater recharge, and a handy tool for future groundwater management measures. Because of the defined connections, any changes in these teleconnections will probably influence the future utilization of the Hungarian groundwater resources.
The geographical scales of fear: spatiality of emotions, emotional spatialities
Authors:   Department of Social and Economic Geography, Eötvös Loránd University (ELTE), Budapest, Hungary, Sági Mirjam
Published: March 2022

A multi-scalar understanding of fear has not been completely absent from geographical theory, however, it has not been given the attention it deserves and definitely has not been utilised in empirical research to the extent it has explanatory power to our globalised world infused with fears. By a multi-scalar understanding I refer to geographical scale as social production or social construction following critical geographers, who see the relationship between these scales as non-hierarchical. This paper draws on and combines theoretical works understanding fear as a socially and politically produced emotion that is politically exploited – most often through Othering – and operates on multiple geographical scales. It is an everyday experience that is produced and made sense across the scales of the body, home, neighbourhood, city, nation, region, supranational unions, the global scale and beyond. This paper draws together three particular areas concerning fear related research; (1) it emphasises that fear is an emotion; but (2) it is deeply embedded in social, economic, political and spatial relations and often closely linked to – if not dependent on – Othering and marginalisation; and (3) fear is reproduced in a transscalar way at all geographical scales. By drawing together these three interlinked approaches to fear, on the one hand, this paper aims to contribute to the literature by demonstrating the way the “us” versus “them” nexus is reimagined at different scales according to political convenience. On the other, it hopes to inspire more research in the field of emotional geography in general and that of fear in particular in Hungary (and more broadly in the CEE region), where this sub-field has been underrepresented even though its great explanatory potentials.

Authors: Kobylarek Aleksander , Błaszczyński Kamil , Ślósarz Luba , Madej Martyna
Published: March 2022

Thesis. The article presents the construction process and psychometric properties of the Critical Thinking Questionnaire (CThQ). The questionnaire is a critical thinking test tool designed for adolescents and adults. The basis for creating the questionnaire was classifying the educational goals proposed by Benjamin Bloom and spread by critical thinking practitioners.

Methods. The independent rater system was used in the construction of the test, while the psychometric properties of the test were tested on a sample of 198 people, calculating the inter-correlation and the Cronbach’s Alpha reliability coefficient.

Result. Both assessments of the independent rater system and research checking the psychometric properties of the test indicate high reliability of the tool. Cronbach’s Alpha coefficient of internal consistency was 0.87. In its final version, the test consists of 25 items, the results of which allow assessing critical thinking in 6 scales: remembering, understanding, applying, analysing, evaluating, and creating. The tool also allows checking the overall score.

The purpose of this research is to formulate and prove the principle of energy of partial subsystems for mechanical, electrical, and electromechanical holonomic systems with time-independent constraints, as well as the development of a simple method to derive equations of motion for such systems. This principle is helpful in giving short courses of theoretical mechanics to students who know only the basic principle of energy and the D’Alembert principle. Two issues are covered in this paper: firstly, the formulation of the principle of energies for interacting mechanical partial subsystems, including the proof of the theorem, and, finally, the application of the developed method for mechanical, electrical, and electromechanical systems. The energy principle is developed using the D’Alembert principle for partial motions of the system when deriving kinetic and power balance equations. For electrical and electromechanical systems, the principle is based on the first electromechanical analogy of Maxwell’s postulate and Kirchhoff 's laws. As examples, the principle allowed obtaining equations of motion of mechanical systems with three degrees of freedom: rotation of a disk on an elastic shaft, dynamics of a vibration table, an electrical system with two cyclic currents connected through a resistor, and an electromechanical system of the acceleration sensor.

TEMPERATURE ASPECTS OF A CUBOID CRYSTAL IN PHOTOACOUSTIC INTERACTION
Authors:   Dr. Annasaheb G.D. Bendale Girls College (Jalgaon, India), Sarode A.P.
Published: March 2022

When a solid crystal undergoes photoacoustic effect, excitation process occurs due to a fraction of incident radiation absorbed by that sample. The nature of excitation depends on the energy of incident radiation. The relaxation processes, generally non-radiative in nature, are observed. Alternate processes of absorption and non- radiative relaxation cause variation in translational temperature in atoms of the crystal. In this paper, the thermal aspects of an isotropic cuboid crystal of elastic material in photoacoustic interaction are presented. This theoretical determination is carried out by applying the finite Marchi–Fasulo integral transform method within the crystal size limitations of a homogeneous cuboid crystal. The results are obtained in terms of infinite series, and the numerical calculations are carried out by using MATHCAD-7 software. The transient translational temperature on the surface of the cuboid crystal in photoacoustic interaction is mathematically determined in terms of thermal conductivity of the elastic material of the crystal.

Authors: NARİN Derya , ONUR Tuğba Özge
Published: March 2022

Cancer is a fatal disease arised from the formation of abnormal cells as a result of random growth in the human body. Lung cancer is the frequently encountered cancer type and causes abnormal growth of lung cells. Diagnosis at an early stage substantially enhances the chance of survivability of the patient, as well as prolongs the survival time. There may even be a complete recovery. For this reason, it is of vital importance to support the diagnosis and detection of doctors and enables them to diagnose more easily and quickly. In this paper, it is aimed to detect lung cancer disease with the help of Alexnet and Resnet50 architectures, which are deep learning architectures, by using computed tomography images. In addition, the performances of the hyper-parameters of maximum epoch and batch size, which are of great importance in training the models, have been compared. According to the results obtained, the highest overall accuracy in automatic detection of lung cancer has been achieved with the AlexNet architecture. The highest overall accuracy value obtained as a result of the simulations is found to be 98.58% with the highest cycle value and the batch size are 200 and 64, respectively.

Stability and Period-Doubling Bifurcation in a Modified Commensal Symbiosis Model with Allee Effect
Authors: IŞIK Seval
Published: March 2022

In this article, the qualitative behaviour of discrete-time commensal symbiosis model which is obtained by implementing the forward Euler’s scheme is discussed in detail. Firstly, the local stability conditions of fixed points of the model are studied. It is proved that the considered model undergoes Period-Doubling bifurcation around coexistence fixed point with the help of bifurcation theory. In order to support the accuracy of obtained analytical finding, some parameter values have been determined and numerical simulations are carried out for these parameter values. Numerical simulations display new and rich nonlinear dynamical behaviours. More specifically, when the parameter 𝛿 is choosen as a bifurcation parameter, it is seen that the considered discrete-time commensal symbiosis model shows very rich nonlinear dynamical.

Uncertainty Estimation for Determination of Potassium Iodate Purity by Potentiometric Titrimetry
Authors: UYSAL Emrah , LİV Lokman
Published: March 2022

The purpose of this study was to express the uncertainty estimation for the purity determination of potassium iodate by potentiometric titrimetry method. Potassium iodate determination by using a potentiometric titrator was realized in two steps. In the first step, a factor analysis is performed using sodium thiosulfate. In the second step, the amount of potassium iodate was determined by using the factor value obtained in the first step of the measurement. Sigma Aldrich 60386 CRM (certified by BAM-with purity of 99.94%) was used for factor analysis. The documents of “Evaluation of measurement data - Guide to the expression of uncertainty in measurement” and “EA-4/02 M: 2013 Evaluation of the Uncertainty of Measurement in Calibration” were the source for the evaluation of the measurement uncertainty. The documents of “EURACHEM/CITAC Guide CG 4, JCGM 100: 2008” and “Eurolab Technical Report No.1/2007” based on the bottom-up approach were also paid regard during the uncertainty estimation study. The main factors that are forming the total uncertainty budget were repeatability of measurement results, titrant consumption, factor of sodium thiosulfate, the molar mass of potassium iodate and sample quantity. It was observed that the highest contribution to the uncertainty budget was the repeatability of measurement results. The measurement result for the purity determination of potassium iodate was found as 99.76% and the expanded uncertainty of the measurements was estimated as 0.12% which was acceptable level for the study.
Analysis of the Effect of Air Gaps on the Electric Field in the Insulation Material of High Voltage Transmission Cables
Authors: ÖZÜPAK Yıldırım
Published: March 2022

High voltage (HV) cables are widely used in the transmission and distribution of electrical energy. The design and manufacture of these cables with great precision are of great importance for power systems. Mistakes made during the manufacturing phase and defects that may occur in the structure of the cable material can cause premature aging and continuous malfunctions in the cables. Factors such as air gaps, foreign substances, and moisture in the insulating material may cause punctures and insulation problems in high voltage cables. In this study, the effects of air gaps left as manufacturing defects on the electric field distribution in the insulation of high voltage cables used in power systems were investigated. The effects of 154 kV high voltage cable, the air gap in different coordinates, and diameters in the insulating layer on the electric field distribution in the cable have been investigated. For this analysis, the Finite Element Method (FEM) and ANSYS@Workbench program which realizes a solution based on this method were used. It has been found that the diameter and location of the air gap significantly affect the electric field distribution of the high voltage cable.
Analysis of the Effectiveness of Various Machine Learning, Artificial Neural Network and Deep Learning Methods in Detecting Fraudulent Credit Card Transactions
Authors: ÇELİK Esra , DAL Deniz , BOZKURT Ferhat
Published: March 2022

A credit card is an important financial tool that has emerged in parallel with the developments in technology from the past to the present and has become an indispensable part of human life. The credit card has many advantages that can be listed as facilitating online shopping, providing installments in purchases, and preventing cash dependence. This is why the rate of use of credit cards worldwide is increasing day by day. On the other hand, there are some risks of the credit cards highlighted by security concerns. The fraudsters who access the identity and credit card information of the consumers through different means use it to shop online without the consumer’s knowledge and gain an unfair advantage. Therefore, it is crucial to eliminate this security vulnerability that the fraudsters exploit and to develop an effective solution to the customer victimization experienced by e-commerce companies due to the fraudulent credit card transactions. With this motivation, the performance of the methods from different research fields was examined to explore the solution space in detail in terms of the problem at hand within the scope of this study. For this purpose, three machine learning algorithms (K-Nearest Neighbor, Naive Bayes, Support Vector Machine), two artificial neural network algorithms (Binary Classifier, Autoencoder), and two deep learning algorithms (Deep Autoencoder and Deep Neural Network Classifier) were implemented. The effectiveness of the algorithms in question was tested with a famous dataset widely used in the literature. Experimental results showed that the Deep Neural Network Classifier outperformed the other algorithms used in this study and the best study ever reported in the literature in detecting fraudulent credit card transactions when accuracy and AUROC performance criteria were taken into account.

In this study, we evaluated the enzyme inhibitory, antimicrobial potentials of S. prostrata. The antimicrobial activity of S. prostrata was measured using three Gram-positive, four Gram-negative bacteria species, and three fungi species. The highest antibacterial activity was detected against the Staphylococcus aureus ATCC 25923 (13±0.81 mm inhibition zone). The enzyme inhibition effect (IC50 values) of S. prostrata were calculated against acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and α-glycosidase (α-Gly) as 2.39 mg/mL, 3.69 mg/ml, and 2.48 mg/mL, respectively.
Abundance and Distribution of Fish in the Zilan Stream (Van/ Turkey) Its Relationship with Some Physicochemical Parameters
Authors: AKKUŞ Mustafa , HUYUT Mehmet Tahir
Published: March 2022

In the recent decades, river regulation attempts, dams and wastewater discharge have not only influenced the water-quality and physical-habitat-structures of the rivers in a bad way but they have also threatened fish-stocks. The aim of this study is to examine the multi-relationship structure between the fish-species-density living in the Zilan-Stream, the largest stream of Lake-Van, and the physicochemical-parameters in this stream. Fish-density was found out with the records from the 12-stations located on Zilan-Stream. From the stations, water-temperature, habitat-score, pH, conductivity, dissolved-oxygen (DO), phosphate (PO4), nitrate (NO3), turbidity and height values were obtained. The correlation structure of the obtained parameters with fish-density was analyzed by canonical-correspondence-analysis (CCA). CCA axes fully explained the response of fish-density to physicochemical-parameters. As a result of the CCA, it was observed that the species concentrated in environments with less-conductivity and low nitrate/pH levels. Species were hypersensitive to altitude, and were found more intensely at mid/low altitudes. In addition, it was observed that the species concentrated in high-habitat score and oxygen-rich stations. It was observed that the species prefer medium/low temperature more and concentrate in environments with low-solids content. It is expected that the data obtained from this study will contribute to the management of areas to be protected in Zilan-Stream.
Angular Dependence of L_α/Ll, Lα/Lβ and Lα/Lγ X-ray Intensity Ratios of Lead at 59.54 keV Photon Energy
Authors: AKKUŞ Tuba
Published: March 2022

L_α/L_l, L_α/L_β and L_α/L_γ x-ray intensity ratios of lead have been calculated at an angular range 85˚-135˚ at 59.54 keV photon energy by using a Si (Li) detector. The results showed that the L_α/L_β and L_α/L_γ intensity ratios decreased as the scattering angle increased. The correlations between the L_α/L_β and L_α/L_γ intensity ratios and scattering angles were also high. On the other hand the variation of L_α/L_l intensity ratio with the scattering angle is irregular.
Making Visible the Invisible
Authors: Crowley Suzanne
Published: March 2022

This article documents how I came to combine autoethnographic accounting with visual arts practice. I developed this mixed methods approach for my PhD study which explores the interdisciplinary possibilities offered by combining visual arts practice with STEM (science, technology, engineering, and mathematics). Visual arts practices as narrative forms tend toward the non-linear (Anae, 2014), whilst autoethnography offers self-reflection. Writing an autoethnographic account for an artwork has the potential to generate a wealth of data, some of which are visible, some of which are not. The invisible data become available only when the artist speaks to/writes about the artwork. If some content/context of a visual artwork is only visible through background information provided by the art maker, this discovery troubles another issue concerning our notions of what a good visual artwork is. Finally, I test this article’s autoethnographic authenticity against Adam’s four characteristics of autoethnography.

Inclinations
Authors: Peers Danielle , Sheppard Alice , Eales Lindsay , Schenk Abbie
Published: March 2022

Inclinations is an audio-described, 7-minute, site-specific, disability dance on film followed by a video discussion between three of the disabled artist-researchers. Throughout this project, we embraced a research-creation methodology to engage with the research question: How can we fully embed intersectional disability justice, not only as a theoretical lens, but also, as a methodological imperative? This work centres the concepts of disability culture and disability generativity, and purposefully diverges from more popular traditions of physically-integrated dance in favour of disability dance. We demonstrate and discuss how this choice—alongside various filmic practices—seeks to decentre the ableist gaze, normalizing narratives, and the ubiquitous non-disabled referent. Other methodological considerations enacted and discussed in this work include centring access aesthetics, consent, care, disability justice principles, and questions of power in every aspect of the creation process.
Thing is Whatever This is That I Can't Say
Authors: Coogler Carlson H.
Published: March 2022

This inquiry exists because of a necklace I made but could not explain. I picked up theory and poetry and set off on a journey to answer why, and what now. How do you articulate the value of something you remain incapable of explaining? In the middle of the journey, I reached the edge of a ravine. This paper is written there, at the lip of the aporia. It is like a letter or a map. It aims to guide you to that uncrossable gap existing between thing and object, thing and us. It invites you to join me—speaking poems about and into that chasm, and hearing strange replies that might be echoes, or new verses—as I make with and despite and because of the mystery. As I inquire into and with the world, gaps and all, to approach things—that which is that I can’t say.

The neoliberal university can be a restrictive, repressive, and/or oppressive space. However, the contributions in this edited publication “Reimagining the Academy: ShiFting towards Kindness, Connection, and an Ethics of Care” by Alison L Black and Rachael Dwyer and published by Palgrave Macmillan represent hope, kindness, love, and compassion. The words and works contained in this book gift to any reader many enriching, impactful storied accounts of academic works from differentiated perspectives. These important works support the re-imagining of academic spaces, scholarship, research, teaching and learning and care for self, others, and the work that matters. My reading of these works engaged my individuated ethic of care and inspired a creative response – artistic and poetic storying as an act of performative synthesis of the experience that awaits the reader.

Background: Infertility is an abnormal event in the life of families and can have various consequences on a personal and social level. Therefore, infertile couples need to manage their emotional responses. Social capital, as one of the social determinants of health, can affect mental health.
Objective: This study was conducted to determine the relationship between social capital and emotional adjustment in infertile couples.
Materials and Methods: This cross-sectional study was conducted from October 2018 to February 2019 with 170 infertile couples visiting infertility centers in Sari, Iran. The data collection instruments included the social capital integrated questionnaire, an emotional adjustment scale and a demographic-reproductive checklist.
Results: All the social capital dimensions, except for the groups and networks dimension, had a score of higher than 50 (more than the mean score). Based on ANCOVA and the multiple linear regression results, the dimension of trust and solidarity had a significant negative relationship with emotional adjustment (p = 0.01), but no significant relationship was observed between the other social capital dimensions and emotional adjustment.
Conclusion: The trust and solidarity dimension had a significant relationship with emotional adjustment in infertile couples. Accordingly, increasing mutual trust between neighborhood residents can strengthen social capital, and in turn, improve emotional adjustment in infertile couples.
Key words: Social capital, Emotional adjustment, Infertility.

Background: Recurrent pregnancy loss (RPL) is a major concern among women worldwide. However, the exact mechanisms underlying miscarriage are not well understood. Recent evidence suggests that single nucleotide polymorphisms in various genes, especially miRNAs, may be responsible for RPL.
Objective: We surveyed the association between polymorphisms in pre-miR-125a, premiR- 10a, pre-miR-323b, GPX4, and GPX4 in Iranian women with idiopathic RPL.
Materials and Methods: DNA was extracted from blood samples of 116 women with idiopathic RPL and 89 healthy women as controls who had previously had at least two successful pregnancies. Polymerase chain reaction was used for the amplification of the genes. Genotype screening along with SNaPshot were performed to detect different polymorphisms. Finally, the polymorphisms and frequency of each genotype were compared between the two groups.
Results: The frequencies of polymorphisms in pre-miR-125a (p < 0.001) and pre-miR-10a (p = 0.04) were calculated among the case and control groups, which showed a statistical difference (p < 0.05), indicating an association between these polymorphisms and the symptoms of RPL. The frequencies of polymorphisms of genotypes in GPX4, COMT and pre-miR-323b did not demonstrate any difference between the two groups. Also, the amount of alleles in pre-miR-125a and pre-miR-10a were significantly different (p < 0.001 and p = 0.02, respectively) and the dominant inheritance model was proposed.
Conclusion: In conclusion, pre-miR-125a and pre-miR-10a can be associated with RPL in women. The SNaPshot technique is a valuable tool to evaluate possible associations between polymorphisms and health conditions.
Key words: SNaPshot, Single-nucleotide polymorphisms, Recurrent pregnancy loss, Genotypes.
A Problemática da Dívida Pública em Mocambique
Authors: Charles Alcinda Rui Francisco Chichava
Published: March 2022

A maior parte da análise sobre a dívida pública de Moçambique começa intencionalmente em 2006, embora ocasionalmente se faça referência a anos anteriores para destacar tendências. A razão para se concentrar em 2006 é o ano em que, após Moçambique ter beneficiado das iniciativas HIPC (Países Pobres Altamente Endividados) e MDRI (Iniciativa Multilateral de Alívio da Dívida), que contribuíram para um regresso à sustentabilidade da dívida pública externa. No período subsequente a esta iniciativa, a dívida pública moçambicana atingiu um mínimo absoluto. Antes das iniciativas PPAE e MDRI, a dívida pública moçambicana atingiu níveis insustentáveis nos anos 90, de tal forma que a dívida externa atingiu mais de 100% e 1000% do PIB e das receitas públicas. O objectivo desta investigação é analisar os factores que determinaram o rápido crescimento da dívida pública de Moçambique de 40% para 120% nos últimos 5 anos. A investigação quanto à abordagem é qualitativa e quanto aos objectivos, é descritiva. Foi utilizado guião de entrevista para a recolha de dados. A pesquisa documental foi utilizada para aceder a material institucional do Ministério da Economia e Finanças, para além da observação durante o processo de recolha de dados. Foi a conclusão desta pesquisa que factores como as más escolhas políticas públicas e a dinâmica do processo da dívida pública determinaram o rápido crescimento da dívida pública no país de 40% para 120% nos últimos 5 anos, com impacto negativo a nível económico, social e político.

Published: March 2022

Introduction: Pseudomonas aeruginosa is an opportunistic pathogen and causes of nosocomial infections in hospitals. Due to high antibiotic resistance and the ability to develop new resistance during antibiotic treatment, Pseudomonas aeruginosa infection is difficult to eradicate because the physical treatment becomes difficult and ineffective. This study was conducted to evaluate the antibiotic sensitivity pattern of Pseudomonas aeruginosa strains at two different hospital in Makassar. Methods: This study is a cross-sectional study from March to May 2021. The research samples were taken from the results of culture and antibiotic sensitivity tests conducted at two different hospital, Hasanuddin University Hospital and Dr. Wahidin Sudirohusodo Hospital for the period January 1 to September 30, 2019. A total of 84 samples were cultured and tested for antibiotic sensitivity of Pseudomonas aeruginosa. Results: Antibiotic sensitivity of Pseudomonas aeruginosa was best with aminoglycoside antibiotics, gentamicin (100%) at Hasanuddin University Hospital and amikacin (95.8%) at Dr. Wahidin Sudirohusodo Hospital. At Hasanuddin University Hospital followed by antibiotics amikacin (92.3%) and meropenem (84.6%). At Dr. Wahidin Sudirohusodo Hospital, Pseudomonas aeruginosa also showed good sensitivity to gentamicin (91.5%) and meropenem (77.5%). The sensitivity of Pseudomonas aeruginosa was lowest to piperacillin/tazobactam. Conclusions:  This study shows that the level of effectiveness of the antibiotics meropenem, amikacin and gentamicin is high enough and it can be used as a treatment option in Pseudomonas aeruginosa infection. This study can help as a reference to prevent mortality and morbidity associated with Pseudomonas aeruginosa infection.

Introduction: IL-1β is one of the proinflammatory cytokines which is commonly found in various diseases, including Chronic Rhinosinusitis (CRS). It has been widely targeted as a therapeutic approach for inflammatory diseases. However, study of IL-1β expression and its correlation with CT-Scan grading scores in CRS is still scarce. Objective: To investigate IL-1β expression based on immunohistochemical examination and analyse its correlation with Lund-Mackay score in CRS with and without polyps. Method: This analytic observational study was done on 50 patients: 25 subjects in the CRS with Nasal Polyps (CRSwNP) group and 25 subjects in the CRS without Nasal Polyps (CRSsNP) group. The uncinate process was taken for immunohistochemical examination of IL-1β. Lund-Mackay score was calculated based on CT-Scan of the paranasal sinus. Result: IL-1β expression in CRSsNP (mean=36.38) was significantly higher than that in the CRSwNP (mean=14.62) with p<0.001. Lund-Mackay score in CRSwNP was higher (mean=35.22) compared to CRSnNP group (mean=15.78) with p<0.001. There was a moderate negative correlation (-0.403) between IL-1β expression and Lund-Mackay score (p<0.05). Conclusion: There was a moderate negative correlation between IL-1β expression and Lund-Mackay score. The IL-1β and the Lund-Mackay score in CRSwNP were lower and higher, respectively, than in CRSsNP

Phonemic Awareness has been reported to be one of the predictors to reading comprehension in English as a first language. However, it also comprises the second language reading comprehension. Various studies have reported the effects of English phonemic awareness to reading comprehension in English as a second or foreign language, but less similar research has been reported involving Indonesian EFL learners. Indonesia and English share different phonemes that affect learners' comprehension on English. This study aims to investigate the correlation between EFL learners’ phonemic awareness and reading comprehension. The subjects selected were 100 students from the 3rd semester majoring in English Language Education Program, in one of Indonesian university. There are two test obtained during this research, the first is phonemic identification test in order to measure the level of phonemic awareness, and the second is reading comprehension test to measure students’ reading comprehension skill. Simple linear regression was applied to validate the influence of English Phonemic Awareness to English Reading Comprehension. The result revealed that the correlation coefficient (r) value between the two variables shows .352 degrees with the significance level .000, while the coefficient of determination (r2) shows .
Lithosphere beneath the Evolving Tianshan Orogen: Constraints from Xenoliths
Authors: Chen Nancy Hui-Chun , Cawood Peter A. , Iizuka Yoshiyuki
Published: March 2022

The Ortosuu and Uchkuduk regions of the Tianshan orogen contain a volumetrically small series of basaltic rocks erupted primarily during the late Mesozoic-Paleogene. Petrology, chemical composition, and P-T geotherm data from xenoliths within the basalts characterize the nature of the lithospheric mantle beneath this orogenic belt. Two groups of clinopyroxene can be identified from the studied xenoliths based on their Mg# and trace element patterns. Group 1, primitive clinopyroxenes, has lower Mg# (86–90) and LREE-depleted patterns than group 2, depleted clinopyroxenes, which are characterized by a relatively high Mg#, 91–92, and LREE-enriched patterns. The REE distribution in group 1 clinopyroxenes suggests that they were controlled by partial melting, whereas group 2 clinopyroxenes are far more complex involving partial melting degrees of 6–11%, and later metasomatism by carbonatite and/or silicate melts. Coupled P-T estimations from geothermobarometry indicate that the more fertile group 1 xenoliths were probably derived from the uppermost mantle, and the more depleted group 2 xenoliths were likely derived from a depth close to the crust mantle boundary.
