AL-HASHADU POETRY BY AHMAD MATAR (AN ANALYSIS OF RIFFATERRE’S SEMIOTICS)
Authors: Umam Muhammad Choirul , Sakinah Nyimas
Published: October 2023

The language used in poetry is different from the use of language in general. In addition being different in usage, poetry expresses a concept and something indirectly. Language in poetry becomes a sign, which semiotics can be studied to reveal the meaning contained in it. This study examines Ahmad Matar’s poetry entitled “al-Hashadu” by using Riffaterre's semiotic theory. This research is a descriptive qualitative research. The method of data collection applied a documentation by reading and recording techniques. The technique of analyzing data used the heuristic and hermeneutic reading techniques. The results showed that: 1) The heuristic reading of al-Hashadu poetry by Aḥmad Maṭar received imperfect meaning, 2) The hermeneutic reading of al-Hashadu  poetry by Aḥmad Maṭar received a complete meaning structurally, 3) The matrix of al-Hashadu poetry by Aḥmad Maṭar was the resistance to colonialism. The model of the poetry is two sentences in the stanzas "Then there will be one left" and "Truly I am an atheist" and 4) The hypogram of al-Hashadu poetry by Aḥmad Maṭar was the resistance of the Arabs to American colonialism.

Jenis limbah B3 dari proses produksi dua diantaranya adalah kadmium dan timbal. Sifat logam berat yang dapat terakumulasi dalam tubuh makhluk hidup (salah satunya manusia) akan mempengaruhi kualitas hidup dan dapat menimbulkan masalah kesehatan pada rentang waktu tertentu. Tujuan adanya penelitian ini adalah untuk mengukur dan menganalisis kadar kadmium dan timbal pada ikan belanak. Penelitian ini merupakan penelitian deskriptif observasional dengan metode survei yang dilakukan di pantai utara. Pengambilan sampel dilakukan menggunakan Teknik incidental sampling pada September 2021 yang dibantu oleh nelayan setempat dengan menggunakan jaring. Kriteria sampel, ikan belanak yang tertarik pada titik sampel yang telah ditentukan, sampel ikan yang didapatkan kemudian dianalisis dengan metode Atomic Absorption Spectrometer (AAS) di salah satu laboratorium di Surabaya. Data kadar kadmium dan timbal pada ikan belanak akan dianalisis dengan menggunakan teknik analisis data univariat. Hasil uji kadar kadmium dan timbal dibandingkan dengan nilai baku mutu yang telah ditetapkan dalam Standar Nasional Indonesia 7378:2009 terkait Batas Maksimum Cemaran Logam Berat dalam Pangan. Kadar kadmium di bawah 0,1 mg/kg atau berkisar antara (-1,1663 sampai -0,0751 mg/kg) sedangkan nilai timbal berada di bawah 0,3 mg/kg atau berkisar antara (-1,2414 sampai -0,5665 mg/kg). Sehingga ikan belanak layak untuk dikonsumsi masyarakat namun tidak berlebihan. Batas maksimum yang dapat ditolelir oleh manusia dalam mengonsumsi ikan belanak dalam satu minggu untuk orang dewasa 12,5 g (setengah ekor ikan belanak ukuran sedang) dan untuk anak-anak 3.75 g (seperempat ekor ikan belanak ukuran sedang). Konsumsi kadmium pada lingkungan yang tercemar jika perhari mencapai 140-260 gram/hari dapat menyebabkan proteinuria. FAO menetapkan asupan kadmium bulanan sementara yang dapat ditoleransi pada tahun 2010 adalah sebesar 25 g/kg berat badan.

Published: October 2023

A comprehensive needs analysis is crucial to guide the design and teaching of English for Specific Purposes (ESP) courses. However, a number of studies neglect certain elements of needs analysis, which can result in problems in subsequent stages of ESP teaching. This mixed-method study aimed to identify the problems that higher education ESP practitioners in Thailand encountered and the solutions they employed and to develop a potential practices model for ESP practitioners. Semi-structured interviews and Analytic Hierarchy Process (AHP) pairwise comparisons were employed to reveal 54 problems in six categories. Three highest-ranked problems were 1) the ESP practitioners’ lack of specialization in relevant fields (34.62%), 2) unsuitable classrooms and facilities (29.15%), and 3) the lack of specific course objective-oriented and cost-effective commercial textbooks (19.09%). The average consistency ratio (C.R.) was 0.32. The study suggested the need for training provisions and inclusion of ESP courses in English curricula. The ESP practices model suggested practices for institutions, such as conducting comprehensive needs analysis and providing suitable facilities and budgets. ESP practitioners were advised to utilize needs analysis for course design and employ active learning approaches. These recommendations aimed to enhance ESP education and improve an English curriculum, teaching practices, and evaluation processes.

Published: October 2023

Potassium-ion batteries (PIBs) have attracted significant attention as a complement to lithium-ion and sodium-ion batteries (SIBs). PIBs can theoretically provide higher specific energy and power density than SIBs due to lower standard electrode potential of K/K+ and faster K+ ion diffusion, maintaining the benefits of low-cost and sustainability. However, research on PIBs is in its infancy; therefore, further efforts are necessary to enhance their performance and position them as a competitive technology. In this perspective, the remaining challenges and possible strategies to advance the development of PIBs are presented.

One of the prospective places for agricultural usage in acid sulfate rice fields, which are typically spread out in lowland areas along coastlines that occasionally undergo flooding. If handled effectively in accordance with the issues found in the land, this site can be developed as a productive agricultural region. Agricultural development on acid sulfate soils frequently encounters a number of issues, including (pH) acidic soil, high iron content, a lack of phosphate availability, and the presence of pyrite (FeS2). In this study, the relationship between P availability, Fe solubility, the Fe-P fraction, pH, Eh, and pyrite depth in acid sulfate paddy fields will be examined. Purposive sampling was used in field research utilizing the survey method in the acid sulphate rice fields of Barito Kuala Regency. This research was based on the distribution map of Fe solubility in Barito Kuala Regency. The results of this study indicate that there are three variables that have a significant effect on P availability: soluble Fe amd Fe-P fraction with the power regression form and a very strong relationship; and soil pH with a linear regression form and a strong relationship. Pyrite depth and soil Eh had no significant relationship with P availability in acid-sulfate lowland rice fields.

Membrane Solution for a Paraboloid under Self-Weight
Authors: Gohnert Mitchell , Bradley Ryan
Published: October 2023

Stress flows in a predictable pattern, and structural optimization is achieved by matching the natural flow of stress with the structural shape. The geometry of the parabolic shape simulates the natural flow of stress, and is therefore highly efficient in the conveyance of stress. However,
despite its importance, the membrane solution of a parabolic dome has never been solved. Designers have been reliant on numerical methods, such as finite elements, or older techniques such as graphical solutions. For this reason, a closed-form membrane solution for a parabolic dome is derived.
The solution solves for the meridian and hoop stresses, in the vertical and horizontal directions of the dome for the case of uniformly distributed loads, such as the self-weight of a uniformly thick shell. Finite element analysis (FEA) was also used to undertake a full shell analysis (i.e.,
membrane and bending behavior) to examine the edge effects that are not captured in the membrane solution. From this study, the benefits of the parabolic dome were found to be similar to the catenary dome; i.e., the stresses in the meridian and hoop directions are compressive, boundary effects
are largely minimal, andstresses flow primarily in-plane (membrane action).

Published: October 2023

Flexible capacity applications demands to large energy storage density and high breakdown electric field strength of flexible films. Here, P(VDF-HFP) with ultra-thin Al2O3 nanosheets composite films were designed and fabricated through an electrospinning process followed by hot-pressing in sandwich structured. The results show that the insulating ultra-thin Al2O3 nanosheets and the sandwich structure can enhance the composites' breakdown field (by 24.8%) and energy density (by 30.6%) remarkedly to P(VDF-HFP) polymer matrix. An energy density of 23.5 J/cm3 at the ultrahigh breakdown field of 740kV/mm can be therefore realized. Insulating test and phase-field simulation results reveal that ultra-thin nanosheets insulating buffer layers can reduce the leakage current in composites, thus it effects the electric field spatial distribution to enhance breakdown strength. Our research provides a feasible method to increase the breakdown strength of ferroelectric polymers, which is comparable to those of non-ferroelectric polymers.

Breast microcalcifications, tiny calcium salt deposits, can develop anywhere in the breast tissue. Breast microcalcifications are a frequent mammographic finding. For a proper diagnosis, it is essential to spot microcalcifications in mammograms as soon as possible because they are a typical early indicator of breast cancer. Computer-based detection output can help the radiologist improve diagnosis accuracy because of their tiny size and tendency to be unseen to the radiologist doing the examination. Because of its small size, it is difficult to notice with the naked eye. The identification of microcalcification is essential for cancer prevention. In this paper, I proposed a linear time-invariant filtering Wiener method with Tophat transformation (LFWT) breast microcalcification detection method, applied mammographic image corrections using a Wiener filter to remove noise, and used Contrast Limited Adaptive Histogram Equitation (CLAHE) to improve mammographic image quality. The Wiener and CLAHE filter makes visible the cancer part. After image enhancement, Tophat morphological operators such as opening and closing are applied and the mask is detected. After that, the edges are extracted and selected according to the actual image. The diagnostic performance of the proposed model was evaluated with MIAS data and In comparison to other techniques for spotting microcalcifications in mammograms. These are Local Contrast Method (LCM), Relative Local Contrast Measure Method (RLCMM), and High-Boost-Based Multiscale Local Contrast Measure (HBBMLCM) techniques used to identify cancer microcalcification on mammography imgaes. The LFWT technique was found to be the most effective for the detection of microcalcification of breast cancer compared to the other three methods. The proposed LFWT technique detects all small and tiny spots. The images used in the LFWT method are taken from the MIAS dataset of the microcalcification for breast cancer detection. Before deploying the images, several steps were carried out to remove artifacts such as pectorals and clipping etc. The result is a breast cancer with nice smooth, safe margins and high quality. All MIAS breast cancer images were recorded and in each image, all microcalcifying spots were detected. In every image, where one or more microcalcifications were found in the mammography images, Microcalcifications were detected in the Mammogram images. Microcalcifications were found in either tumor or non-tumour images.

Authors: Pilon Clémence Bertrand , Arguin Martin

This study examined the temporal profile of spatial frequency processing in a word reading task in 16 normal adult readers. They had to report the word presented in a 200 ms display using a four-alternative forced-choice task (4AFC). The stimuli were made of an additive combination of the signal (i.e. the target word) and of a visual white noise patch wherein the signal-to-noise ratio varied randomly across stimulus duration. Four spatial frequency conditions were defined for the signal component of the stimulus (bandpass Butterworth filters with center frequencies of 1.2, 2.4, 4.8 and 9.6 cycles per degree). In contrast to the coarse-to-fine theory of visual recognition, the results show that the highest spatial frequency range dominates early processing, with a shift toward lower spatial frequencies at later points during stimulus exposure. This pattern interacted in a complex way with the temporal frequency content of signal-to-noise oscillations. The outcome of individual data patterns classification by a machine learning algorithm according to the corresponding spatial frequency band further shows that the most salient spatial frequency signature is obtained when the time dimension within data patterns is recoded into its Fourier transform.

This study aims to explore the factors related to fact-checking about the pandemic and the moderating role of gender on the effects of explored factors. Based on social cognitive theory and social role theory, we established a research model to explore the factors of fact-checking on the pandemic and the role of gender. To validate the research model, data were collected by survey method and analyzed by partial least squares technique. The analysis results present that personal factor (self-efficacy and outcome expectancy) and environmental factors (perceived skepticism and perceived ambiguity) have significant impacts on fact-checking about the COVID-19 pandemic. Meanwhile, our results reveal that gender moderates the effects of outcome expectancy, perceived skepticism, and perceived ambiguity on users’ fact-checking. Our study uses social cognitive theory to explore the factors impacting fact-checking, while we combine with social role theory to understand the gender differences in the process of COVID-19 fact-checking in SNSs.

Current methodologies to predict methane (CH4) production have disadvantages such as high acquisition and implementation costs, the impossibility of reconciling animal evaluation at pasture with more accurate results, and time needed for measurements. Infrared thermography may be an alternative technology for measuring the amount of CH4 produced and has the advantages of low cost, speed and efficiency in obtaining results. The objective of the study was to determine if the infrared thermography is adequate for predicting the emission of CH4 in hair sheep and the best time after feeding to carry out the measurement. Twelve Santa Inês lambs remained for two days in respirometric chambers, in a semi-closed system, to determine the CH4 production. The animals were divided into two treatments, according to the diet provided. During this period, seven thermographic photographs were taken, at times − 1h, -0.5h, 0h, 0.5h, 1h, 2h, 3h, 5h, and 7h, according to the feeding time, defined as 0h. CH4 production was measured over 24 hours. Thermographic images were used to measure the maximum, minimum, average and point temperatures at the left and right flanks. At each time, the temperature difference between the left and right flanks (left minus right) was calculated. Pearson correlation coefficients, multiple regression and principal component analysis, were carried out in SAS®. For sheep, the time three hours after feeding was considered ideal to predict the CH4 production with the use of infrared thermography images. At hour seven post-feeding, a significant increase in temperature differences were observed, suggesting a new peak of CH4 production.

In clinical practice, renal ischemia-reperfusion injury (IRI) is a common cause of acute kidney injury (AKI), often leading to acute renal failure or end-stage renal disease (ESRD). The current understanding of renal IRI mechanisms remains unclear, and effective therapeutic strategies and clear targets are lacking. Therefore, the need to find explicit and effective ways to reduce renal IRI remains a scientific challenge. The current study explored pyroptosis, a type of inflammation-regulated programmed cell death, and the role of Gasdermins E (GSDME)-mediated pyroptosis, mitochondrial damage, and inflammation in renal IRI. The analysis of human samples showed that the expression levels of GSDME in normal human renal tissues were higher than those of GSDMD. Moreover, our study demonstrated that GSDME played an important role in mediating pyroptosis, inflammation, and mitochondrial damage in renal IRI. Subsequently, GSDME-N accumulated in the mitochondrial membrane, leading to mitochondrial damage and activation of caspase3, which generated a feed-forward loop of self-amplification injury. However, GSDME knockout resulted in the amelioration of renal IRI. Moreover, at the low expression levels of GSDME, activated caspase3 mediated apoptosis, while at the high expression levels of GSDME, apoptosis was switched to pyroptosis. The current study found that the transcription factor CHOP was activated much earlier in renal IRI. On one hand, CHOP inhibited BCL-2, leading to mitochondrial damage and apoptosis, while on the other hand, it was positively regulated GSDME expression, enabling the conversion of apoptosis to pyroptosis.Therefore, this study explored the transcriptional mechanisms of GSDME during IRI development and the important role of CHOP/Caspase3/GSDME mechanistic axis in regulating apoptosis and pyroptosis in renal IRI. This axis might serve as a potential therapeutic target.

Streptococcus ruminantium is the causative agent of several bovine and ovine diseases, however reports are uncommon and application of whole genome sequencing to identify is rare. We report for the first time, a severe ovine mastitis outbreak caused by S. ruminantium in Italy, 2022. S. ruminantium was isolated from 12 adult lactating ewes with diffuse nodules in the mammary parenchyma and predominantly serous and clotted milk. All outbreak isolates, along with five additional historical Italian isolates (between 2011 and 2017), were genomically characterised and then analysed in the context of all publicly available S. ruminantium genomes. Antimicrobial susceptibility testing was performed to determine the MICs of 16 antibiotics. The results showed that all isolates were susceptible to all antimicrobials tested except kanamycin. Single Nucleotide Variant analysis confirmed this as a clonal outbreak across 10 sheep (≤ 15 SNVs), while the two others were colonised by more distantly related clones (≤ 53 pairwise SNVs), indicating the presence of multiple infecting lineages. The five historical S. ruminantium isolates were comprised of genetically-distant singletons (between 1259–5430 pairwise SNVs to 2022 outbreak isolates). Ovine isolates were found to be genetically distinct to bovine isolates, forming monophyletic groups. Bovine isolates were similarly made up of singleton clones in all but two isolates. Taken together, our genomic analysis using all globally available genomes is consistent with general opportunistic pathogenesis of S. ruminantium. We encourage future genomic surveillance efforts to facilitate outbreak detection, as well as improve our understanding of this poorly-understood, multi-host, zoonotic pathogen.
Effect of Certain Genetic Variants in Nicotinic AChR on Substance Addictions: A Structural Equation Modeling Approach
Authors: Albayrak Muammer , Turhan Kemal
Published: October 2023

Nicotine addiction, like many other addictions, is a complex form of behavior with both genetic and environmental aspects. Although there is a need for studies investigating the interaction between environmental and genetic factors in the field of substance addiction, the number of studies that consider both aspects is limited. This study explored how certain genetic variants in the nicotine acetylcholine receptor (AChR) genes interact with nicotine and other types of substance addiction and environment. From the genetic data of 66936 variants, scores generated by Polygenic Risk Score (PRS) analysis for certain genetic variants found in nicotinic AChR genes. The relationship between this score and Wisconsin Index of Smoking Dependence Motives (WISDM), socio-economic status (SES), nicotine and other substance addictions was examined using structural equation modeling (SEM). The data set contains information of 2969 subjects (Female (1786) Male (1168)). PRS had a significant effect on the FTND as expected. PRS also showed a significant effect on alcohol addiction and marijuana addiction with higher coefficients than FTND. SES significantly affects WISDM. WISDM showed a significant effect on alcohol, marijuana, cocaine and opiate addiction. Thus, WISDM was examined as mediator of the relationship between SES and substance addictions. Alcohol addiction significantly affects nicotine, cocaine and marijuana addiction. These findings suggest that certain genetic variants in nicotinic AChR known to affect one type of addiction may also have an effect on other types of substance addictions. In addition, nicotinic AChR may be a clinically significant target for prevention of substance addictions other than nicotine.
