Determination of the amount of infiltration supply according to the data of low-water runoff in a tailing storage area
Authors: Lyamin I. A. 
Published: October 2022

Background. The relevance of the study lies in predicting the hydrogeological regime in the process of construction and operation of tailing storage areas. A complex study of the aeration zone and formation conditions of infiltration supply will make it possible to minimize the anthropogenic load on the hydrosphere and to develop measures for a reduction in the negative load on territories imposed to anthropogenic impact.Aim. To determine the amount of infiltration supply in a designed tailing storage area.Materials and methods. The studied territory is the southern part of the Talitsky section of the Verkhnekamsk salt deposit (Russian Federation). The studied objects included infiltration processes, weakly-permeable deposits, and drainage network. The applied methods involved mathematical modelling, mapping, and hydrometric works.Results. The conducted works reflect the regularities characteristic of the drain of small rivers in the region under study. Melted snow waters play a leading role in feeding surface watercourses. The most intensive inflow of rainwater, corresponding to the periods of summer and autumn rain floods, on the rivers of the study area occurred in July 2017 and in October–November 2017. Some differences in the annual volume of the run-off distribution of this water flow are likely to be determined by a change in the characteristics of the water-collecting area occurring as a result of cutting down forests and preparing the territory for construction of a mining and processing plant.
Hydrogeology of the artesian basins of the southern part of the Kara sea and Yamal-Gydansk megasaddle
Authors: Vlasenko S. S. 
Published: October 2022

Background. In hydrogeological terms, the territory of the Barents-Kara shelf has not been studied in sufficient detail. The data on its hydrogeological zoning are based mainly on the results of research undertaken in the 1970s, when attempts were made to isolate artesian shelf basins according to a set of hydrogeological indicators of oil and gas content. Currently, the position of the basin boundaries can be adjusted using current data from oil and gas and geological zoning and the hydrogeological testing of wells.Aim. To conduct the hydrogeological zoning of the territory of the southern part of the Kara Sea and the north of the West Siberian geosyneclise, including oil and gas structures — the South Kara syneclise and the Yamal-Gydan megasaddle, as well as to carry out a chemical analysis of groundwater of the Jurassic-Cretaceous aquifer complexes composing the sediments of the sedimentary cover of the West Siberian sedimentary basin.Materials and methods. A cartographic method was used to analyze earlier maps and schemes of hydrogeological and oil and gas geological zoning of the Russian sector of the continental slope of the Arctic Ocean, and then to determine the boundaries of the identified artesian basins. For a chemical analysis of groundwater, the results of hydrogeological testing of wells drilled at the Zapolyarnoye oil and gas condensate field were used.Results. The boundaries of two artesian basins — the South Kara submarine and the Yamal-Gydan semi-marine, corresponding to the same-name oil and gas prospective structures and having the same geological structure, were determined. Both basins are characterised by the presence of the main aquifer complexes of the Mesozoic hydrogeological floor of Western Siberia. When studying the composition of groundwater of the Zapolyarnoye deposit, it was found that the types of water change regularly with depth and an increase in the content of the hydrocarbonate ion due to the possible migration of fluids enriched with carbonic acid dioxide from the rocks of the foundation.Conclusion. The determined basins are characterised by a wide distribution of oil and gas-bearing structures and the exploration maturity of the sedimentary cover. Both artesian basins are characterized by the distribution of groundwater of a unified composition and genesis.

<p><em>BACKGROUND:</em> Conventional frequency quantitative ultrasound in conjunction with textural analysis techniques was investigated to monitor noninvasively the effects of cancer therapies in an <em>in vivo</em> preclinical model. <em>METHODS:</em> Conventional low-frequency (∼7 MHz) and high-frequency (∼20 MHz) ultrasound was used with spectral analysis, coupled with textural analysis on spectral parametric maps, obtained from xenograft tumor-bearing animals (<em>n</em> = 20) treated with chemotherapy to extract noninvasive biomarkers of treatment response. <em>RESULTS:</em> Results indicated statistically significant differences in quantitative ultrasound-based biomarkers in both low- and high-frequency ranges between untreated and treated tumors 12 to 24 hours after treatment. Results of regression analysis indicated a high level of correlation between quantitative ultrasound-based biomarkers and tumor cell death estimates from histologic analysis. Applying textural characterization to the spectral parametric maps resulted in an even stronger correlation (<em>r</em>2 = 0.97). <em>CONCLUSION:</em> The results obtained in this research demonstrate that quantitative ultrasound at a clinically relevant frequency can monitor tissue changes <em>in vivo</em> in response to cancer treatment administration. Using higher order textural information extracted from quantitative ultrasound spectral parametric maps provides more information at a high sensitivity related to tumor cell death. </p>

<p>Opto-acoustic imaging involves using light to produce sound waves for visualizing blood in biological tissue. By using multiple optical wavelengths, diagnostic images of blood oxygen saturation and total hemoglobin are generated using endogenous optical contrast, without injection of any external contrast agent and without using any ionizing radiation. The technology has been used in recent clinical studies for diagnosis of breast cancer to help distinguish benign from malignant lesions, potentially reducing the need for biopsy through improved diagnostic imaging accuracy. To enable this application, techniques for mapping oxygen saturation differences within tissue are necessary. Using biologically relevant opto-acoustic phantoms, we analyze the ability of an opto-acoustic imaging system to display colorized parametric maps that are generated using a statistical mapping approach. To mimic breast tissue, a material with closely matching properties for optical absorption, optical scattering, acoustic attenuation, and speed of sound is used. The phantoms include two vessels filled with whole blood at oxygen saturation levels determined using a sensor-based approach. A flow system with gas-mixer and membrane oxygenator adjusts the oxygen saturation of each vessel independently. Datasets are collected with an investigational Imagio® breast imaging system. We examine the ability to distinguish vessels as the oxygen saturation level and imaging depth are varied. At depth of 15 mm and hematocrit of 42%, a sufficient level of contrast to distinguish between two 1.6-mm diameter vessels was measured for an oxygen saturation difference of ∼4.6  %  . In addition, an oxygenated vessel was visible at a depth of 48 mm using an optical wavelength of 1064 nm, and a deoxygenated vessel was visible to a depth of 42 mm with 757 nm. The results provide insight toward using color mapped opto-acoustic images for diagnosing breast cancer. </p>
Photoacoustic ultrasound spectroscopy for assessing red blood cell aggregation and oxygenation
Authors: Hysi Eno , K. Saha Ratan , Kolios Michael 
Published: October 2022

<p>Red blood cell (RBC) aggregation and oxygenation are important markers for a variety of blood disorders. No current technique is capable of simultaneously measuring aggregation/oxygenation levels noninvasively. We propose using photoacoustic ultrasound spectroscopy (PAUS) for assessing both phenomena. This technique relies on frequency-domain analysis of the PA signals by extracting parameters such as the ultrasound spectral slope and the midband fit. To investigate the effect of hematocrit, aggregation, and oxygenation levels on PAUS parameters, a Monte Carlo-based theoretical model and an experimental protocol using porcine RBCs were developed. The samples were illuminated at 750 and 1064 nm and changes in the PAUS parameters were compared to the oxygen-dependent optical absorption coefficients to assess the oxygenation level. Good agreement between the theoretical and experimental spectral parameters was obtained for the spectral slope of the nonaggregated spectra ( <strong>~ 0.3 dB / MHz</strong>). The experimental midband fit increased by <strong>~ 5 dB</strong> for the largest aggregate size. Based on the analysis of the PA signals, the oxygen saturation level of the most aggregated sample was <strong>> 20%</strong> greater than the nonaggregated sample. The results provide a framework for using PA signals' spectroscopic parameters for monitoring the aggregation and oxygenation levels of RBCs. </p>
THE IMPACT OF THE PCE MC CORRECTION VALUE USING MODIFIED AVERAGE TIME HEADWAY METHOD TO ROAD PERFORMANCE (CASE STUDY: VETERAN STREET, MALANG CITY)
Authors: Wardhani Primasari Cahya , Alfiansyah Ahmad Dzulfiqar 
Published: October 2022

Passenger Car Equivalent (PCE) is a conversion factor of various types of vehicles compared to passenger cars or other light vehicles concerning their impact on traffic behavior. The PCE value used in calculating the performance of urban roads refers to Manual Kapasitas Jalan Indonesia (MKJI 1997) as an Indonesian Highway Capacity Manual. There have been many changes in traffic behavior nowadays compared to in 1997. The calculation of the PCE MC value using the average time headway method does not match the actual conditions. Therefore, modifications are needed by calculating the vehicle dimension factors to obtain the PCE value. The result of the PCE MC calculation using the modified average time headway method shows 0.17. This value is smaller than the value of the PCE MC set by the MKJI 1997, which shows 0.25. Based on the analysis of traffic conditions for ten years, the DS value using the PCE MC according to the MKJI 1997 obtains DS>1. Meanwhile, the DS value calculated based on the corrected PCE MC has DS<1. The difference in the value of PCE MC has implications for road performance. As a result, it affects traffic maintenance management in the form of maintenance costs and decision-making.

Kader UKS (Usaha Kesehatan Sekolah) merupakan penunjang penting promosi kesehatan di lingkungan sekolah. Kader UKS perlu memiliki literasi yang baik tentang gizi dan pemilihan bahan makanan sehat. Kegiatan pengabdian masyarakat ini dilakukan sebanyak 2 sesi. Edukasi sesi 1 dilakukan secara virtual tentang gizi seimbang dan pemilihan bahan makanan sehat, sedangkan sesi 2 dilakukan pelatihan luring tentang cara penentuan status gizi remaja melalui praktik pengukuran berat badan, tinggi badan, dan perhitungan indeks massa tubuh (IMT)/ umur. Evaluasi edukasi sesi 1 yang dilakukan pada 22 siswa kader UKS menunjukkan peningkatan skor rata-rata yaitu dari 6 menjadi 8. Evaluasi edukasi sesi 2 menunjukkan seluruh siswa dapat mempraktikkan pengukuran status gizi remaja. Evaluasi pasca kegiatan yang dilakukan 7 setelah edukasi sesi 1 melalui survei pemilihan bahan makanan menunjukkan rata-rata keragaman pangan siswa tergolong sedang. Bahan makanan yang banyak dikonsumsi oleh siswa adalah kelompok bahan pangan serelia, sayur dan buah (non sumber vitamin A), telur, kacang-kacangan, dan bijibijian. Keragaman pangan tersebut masih perlu ditingkatkan karena sebagai bagian dari promotor kesehatan, seharusnya kader UKS dapat mempraktikkan pola makan yang sehat. Secara umum, kegiatan pengabdian masyarakat ini berhasil meningkatkan pengetahuan siswa tentang pemilihan bahan makanan sehat dan keterampilan siswa dalam mengukur status gizi. Meskipun demikian, praktik siswa dalam pemilihan bahan makanan yang beragam perlu ditingkatkan terutama dengan cara intervensi yang melibatkan pihak sekolah dan wali murid terutama dalam upaya penyediaan bahan makanan yang beragam dan sehat di sekolah dan di rumah.

Authors: Suliman Wijdan 
Published: October 2022

The present paper focuses on pinpointing the implications of Oral presentation for fostering learners’ autonomy by employing experimental and qualitative research methods. The study investigated a group of participants comprised of 15 students majoring in English as a foreign language (EFL) at Qassim University. The key data was collected from the participants who were interviewed through a focusing group interview conducted on purpose to obtain a deeper insight into Saudi learners’ perceptions of how oral presentation provides opportunities for them to foster autonomy learning. The results are enlightening, as the students of College of Science and Arts in Al Asyah comprised in the sample find an overall positive satisfaction with the oral presentation as they believed that oral presentation did not only help them decide on materials, plan and prepare it for a class presentation but also it provided them with motivation to learn English, gained self-esteem, confidence and become active learners. Finally, oral presentation stimulated learners to create their own identity of learning the English language and enabled them to sort out their learning materials that satisfy their learning needs.
The Positive Effects of Problem-Based Learning Activities Toward Indonesian EFL Learners' Productive Language Skills
Authors: Wijaya Kristian Florensio 
Published: October 2022

Abstract
With the rapid globalization occurring all around the globe, educational landscapes also underwent some dramatic shifts in terms of teaching methods, policy-makers, and school culture. One of those indispensable trajectories that need to be taken into account by EFL educators is the pedagogical approach. Since learners no longer learn directly from one-on-one interaction with their teachers, it has been high time for educationalists to supersede their teaching-centered with the student-centered learning approach. In Indonesian EFL productive language learning contexts; speaking and writing, it is strongly believed that problem-based learning activities will enable learners to be more confident, autonomous, spirited, and proficient speakers as well as writers. This present qualitative study was plied in the support of document analysis by integrating 30 prior problem-based learning studies held in our archipelago in order to encourage Indonesian ELT experts, practitioners, and policy-makers to start to incorporate this student-centered learning approach in their both speaking and writing learning vicinities. The obtained results revealed 3 positive L2 productive language-learning merits potentially promoted by problem-based learning activities namely: 1) Learners can be more productive L2 academicians, (2) Learners transformed into more high quality and autonomous L2 writers, and (3) Learners progressively became more confident as well as proficient L2 speakers. Following all of these 3 core beneficial productive L2 learning values, contextual, hands-on, and pleasurable problem-based learning design should be well established at the commencement of speaking and writing learning activities to disseminate more holistic learning outcomes progressively for learners.

Published: October 2022

Alzheimer’s disease (AD) is a neurodegenerative disease caused by neurons damage in the brain, and it poses a serious threat to human life and health. No efficient treatment is available, but early diagnosis, discovery, and intervention are still crucial, effective strategies. In this study, an electrochemical sensing platform based on a superwettable microdroplet array was developed to detect multiple AD biomarkers containing Aβ40, Aβ42, T-tau, and P-tau181 of blood. The platform integrated a superwettable substrate based on nanoAu-modified vertical graphene (VG@Au) into a working electrode, which was mainly used for droplet sample anchoring and electrochemical signal generation. In addition, an electrochemical micro-workstation was used for signals conditioning. This superwettable electrochemical sensing platform showed high sensitivity and a low detection limit due to its excellent characteristics such as large specific surface, remarkable electrical conductivity, and good biocompatibility. The detection limit for Aβ40, Aβ42, T-tau, and P-tau181 were 0.064, 0.012, 0.039, and 0.041 pg/ml, respectively. This study provides a promising method for the early diagnosis of AD.

Ionic engineering is exploited to substitute Bi cations in BiFe0.95Mn0.05O3 NPs (BFM) with rare-earth (RE) elements (Nd, Gd, and Dy). The sol-gel synthesized RE-NPs are tested for their magnetic hyperthermia potential. RE-dopants alter the morphology of BFM NPs from elliptical to rectangular to irregular hexagonal for Nd, Gd, and Dy doping, respectively. The RE-BFM NPs are ferroelectric and show larger piezoresponse than the pristine BFO NPs. There is an increase of the maximum magnetization at 300 K of BFM up to 550% by introducing Gd. In hyperthermia tests, 3 mg/ml dispersion of NPs in water and agar could increase the temperature of the dispersion up to ∼39°C under an applied AC magnetic field of 80 mT. Although Gd doping generates the highest increment in magnetization of BFM NPs, the Dy-BFM NPs show the best hyperthermia results. These findings show that RE-doped BFO NPs are promising for hyperthermia and other biomedical applications.
