To reduce the water footprint in agriculture, the recent push toward precision irrigation management has initiated a sharp rise in photonics-based hydration sensing in plants in a non-contact, non-invasive manner. Here, this aspect of sensing was employed in the terahertz (THz) range for mapping liquid water in the plucked leaves of Bambusa vulgaris and Celtis sinensis. Two complementary techniques, broadband THz time-domain spectroscopic imaging and THz quantum cascade laser-based imaging, were utilized. The resulting hydration maps capture the spatial variations within the leaves as well as the hydration dynamics in various time scales. Although both techniques employed raster scanning to acquire the THz image, the results provide very distinct and different information. Terahertz time-domain spectroscopy provides rich spectral and phase information detailing the dehydration effects on the leaf structure, while THz quantum cascade laser-based laser feedback interferometry gives insight into the fast dynamic variation in dehydration patterns.
Fully Cross-Attention Transformer for Guided Depth Super-Resolution
Authors: Ariav Ido , Cohen Israel
Published: March 2023

Modern depth sensors are often characterized by low spatial resolution, which hinders their use in real-world applications. However, the depth map in many scenarios is accompanied by a corresponding high-resolution color image. In light of this, learning-based methods have been extensively used for guided super-resolution of depth maps. A guided super-resolution scheme uses a corresponding high-resolution color image to infer high-resolution depth maps from low-resolution ones. Unfortunately, these methods still have texture copying problems due to improper guidance from color images. Specifically, in most existing methods, guidance from the color image is achieved by a naive concatenation of color and depth features. In this paper, we propose a fully transformer-based network for depth map super-resolution. A cascaded transformer module extracts deep features from a low-resolution depth. It incorporates a novel cross-attention mechanism to seamlessly and continuously guide the color image into the depth upsampling process. Using a window partitioning scheme, linear complexity in image resolution can be achieved, so it can be applied to high-resolution images. The proposed method of guided depth super-resolution outperforms other state-of-the-art methods through extensive experiments.
Indirect Time-of-Flight with GHz Correlation Frequency and Integrated SPAD Reaching Sub-100 µm Precision in 0.35 µm CMOS
Authors: Hauser Michael , Zimmermann Horst , Hofbauer Michael
Published: March 2023

The purpose of this work is to prove the suitability of integrated single-photon avalanche diode (SPAD)-based indirect time-of-flight (iTOF) for sub-100 µm precision depth sensing using a correlation approach with GHz modulation frequencies. For this purpose, a prototype containing a single pixel consisting of an integrated SPAD, quenching circuit, and two independent correlator circuits was fabricated in a 0.35 µm CMOS process and characterized. It achieved a precision of 70 µm and a nonlinearity of less than 200 µm at a received signal power of less than 100 pW. Sub-mm precision was achieved with a signal power of less than 200 fW. These results and the simplicity of our correlation approach underline the great potential of SPAD-based iTOF for future depth sensing applications.

Authors: Singh Sandeep Pratap , Tiwari Shamik
Published: March 2023

Identity management describes a problem by providing the authorized owners with safe and simple access to information and solutions for specific identification processes. The shortcomings of the unimodal systems have been addressed by the introduction of multimodal biometric systems. The use of multimodal systems has increased the biometric system’s overall recognition rate. A new degree of fusion, known as an intelligent Dual Multimodal Biometric Authentication Scheme, is established in this study. In the proposed work, two multimodal biometric systems are developed by combining three unimodal biometric systems. ECG, sclera, and fingerprint are the unimodal systems selected for this work. The sequential model biometric system is developed using a decision-level fusion based on WOA-ANN. The parallel model biometric system is developed using a score-level fusion based on SSA-DBN. The biometric authentication performs preprocessing, feature extraction, matching, and scoring for each unimodal system. On each biometric attribute, matching scores and individual accuracy are cyphered independently. A matcher performance-based fusion procedure is demonstrated for the three biometric qualities because the matchers on these three traits produce varying values. The two-level fusion technique (score and feature) is implemented separately, and their results with the current scheme are compared to exhibit the optimum model. The suggested plan makes use of the highest TPR, FPR, and accuracy rates.

Published: March 2023

The aim of this study was to evaluate the performance of a reverse osmosis (RO) membrane in surfactant removal using various surfactant model aqueous solutions. The separation tests were performed with laboratory scale units in a dead-end configuration. Cellulose Acetate (CA) and Polyamide (PA) RO membranes were used with nonionic, anionic, or cationic surfactants at a wide range of concentrations. Membrane performance was evaluated using permeate flux and total organic carbon (TOC) rejection. The effects of surfactant type and concentration on RO membranes were assessed. Permeate flux of the PA membrane depended on the surfactant type and concentration. The separation of cationic surfactant aqueous solutions yielded the lowest permeate flux, followed by nonionic and anionic surfactant aqueous solutions, respectively. Surfactant adsorption on the membrane surface occurred at very low concentration of cationic and nonionic surfactants due to electrostatic and hydrophobic interactions, respectively, which affected permeate flux, and micelles did not affect the permeate flux of PA membrane. However, for CA membrane the permeate flux was not affected by the feed solution. Both membranes exhibited satisfactory TOC rejection (92–99%). This study highlights the importance of assessing interactions between membrane material and surfactant molecules to mitigate membrane fouling and guarantee a better performance of the RO membrane.
Involvement of Local Authorities in the Protection of Residents’ Health in the Light of the Smart City Concept on the Example of Polish Cities
Authors: Wielicka-Gańczarczyk Karolina , Jonek-Kowalska Izabela
Published: March 2023

According to the modern guidelines of the Smart City (SC) concept, smart cities are not only cities that are above average in terms of technology, but first and foremost are focused on the needs of their residents. A key need for quality of life is taking care of health, including education, prevention, and access to medical infrastructure. In the context of the given circumstances, this article seeks to answer the following research question: What is the level of involvement of local authorities in protecting the health of residents in Polish cities in the context of the Smart City concept? The involvement of local authorities in healthcare is considered in five aspects: (1) monitoring of residents’ health needs; (2) health education; (3) preventive healthcare; (4) healthcare infrastructure; and (5) environment and recreation. To obtain answers to the above research problem, surveys were conducted at the local government level in 399 Polish cities. The research utilized statistical measures of central tendency, indices of variation, and measures of interdependence. The results allow formulating the following key conclusions: (1) most of the surveyed cities do not monitor the health needs of their residents, contrary to the recommendations of the SC concept; (2) cities take measures to protect the health of their residents, but these are focused on sports and recreation; (3) the most neglected health areas are health education and environmental and climate protection. The level of involvement of the city authorities in protecting the health of residents is therefore quite low and is mainly image-related. The lack of monitoring of the expectations of the local community has a negative impact on the effectiveness of healthcare activities and the real improvement in the quality of urban life. Meanwhile, according to research results, cooperation with residents and care for meeting their needs is an important determinant of the effectiveness of healthcare. Given the above conditions, it is difficult to be effective both in terms of improving the quality of life of residents and developing fully sustainable smart cities. The research also shows that the involvement of the city authorities in holistic pro-health activities increases with the size of the city, which means that larger entities are more aware of cooperation with stakeholders and the importance of health for quality of life. Therefore, they are better prepared to implement the assumptions of the Smart City concept. The originality and scientific value of the conducted analysis will help fill the research gap in identifying the health determinants of Smart City development and assessing the involvement of city authorities in protecting the health of residents in a multifaceted perspective.
Combined X-ray and Neutron Powder Diffraction Study on B-Site Cation Ordering in Complex Perovskite La2(Al1/2MgTa1/2)O6
Authors: Sohn Yoo Jung , Baran Volodymyr , Gilles Ralph , Roth Georg , Vaßen Robert
Published: March 2023

Complex perovskite La2(Al1/2MgTa1/2)O6 (LAMT) crystallizes in a monoclinic unit cell with space group P21/n at room temperature. Its B-site cations are ordered in a rock-salt-type arrangement. Previously, the full occupancy of Mg on the 2c-Wyckoff position was deduced from powder X-ray diffraction (PXRD). However, conventional X-rays could not properly resolve the mixed occupation on the B-site, since there is little scattering contrast between the neighbouring elements Mg and Al of the periodic table. Hence, complementary neutron diffraction studies were carried out to verify the exact B-site cation ordering in the unit cell. In this specific configuration of the B-cations, with its occupancy ratio and the presence of a heavy element Ta as well as neighbouring elements Mg and Al, only the strategy of a combined Rietveld analysis using both the X-ray and neutron diffraction data simultaneously succeeded in elucidating an accurate B-site cation ordering in this complex perovskite system. A full occupancy of Mg on the 2c-Wyckoff position and each a half occupancy of Al and Ta on the 2d-Wyckoff position could be resolved for the rock-salt-type ordering of the B-site cations in the monoclinic unit cell of LAMT.

Published: March 2023

Algal blooms consisting of potentially toxic cyanobacteria are a growing source water management challenge faced by water utilities globally. Commercially available sonication devices are designed to mitigate this challenge by targeting cyanobacteria-specific cellular features and aim to inhibit cyanobacterial growth within water bodies. There is limited available literature evaluating this technology; therefore, a sonication trial was conducted in a drinking water reservoir within regional Victoria, Australia across an 18-month period using one device. The trial reservoir, referred to as Reservoir C, is the final reservoir in a local network of reservoirs managed by a regional water utility. Sonicator efficacy was evaluated through qualitative and quantitative analysis of algal and cyanobacterial trends within Reservoir C and surrounding reservoirs using field data collected across three years preceding the trial and during the 18-month duration of the trial. Qualitative assessment revealed a slight increase in eukaryotic algal growth within Reservoir C following device installation, which is likely due to local environmental factors such as rainfall-driven nutrient influx. Post-sonication quantities of cyanobacteria remained relatively consistent, which may indicate that the device was able to counteract favorable phytoplankton growth conditions. Qualitative assessments also revealed minimal prevalence variations of the dominant cyanobacterial species within the reservoir following trial initiation. Since the dominant species were potential toxin producers, there is no strong evidence that sonication altered Reservoir C’s water risk profiles during this trial. Statistical analysis of samples collected within the reservoir and from the intake pipe to the associated treatment plant supported qualitative observations and revealed a significant elevation in eukaryotic algal cell counts during bloom and non-bloom periods post-installation. Corresponding cyanobacteria biovolumes and cell counts revealed that no significant changes occurred, excluding a significant decrease in bloom season cell counts measured within the treatment plant intake pipe and a significant increase in non-bloom season biovolumes and cell counts as measured within the reservoir. One technical disruption occurred during the trial; however, this had no notable impacts on cyanobacterial prevalence. Acknowledging the limitations of the experimental conditions, data and observations from this trial indicate there is no strong evidence that sonication significantly reduced cyanobacteria occurrence within Reservoir C.

Introduction: Malaria and soil-transmitted helminth (STH) co-infection is an important parasitic infection affecting populations in co-endemic countries including Equatorial Guinea. To date, the health impact of STH and malaria co-infection is inconclusive. The current study aimed to report the malaria and STH infection epidemiology in the continental region of Equatorial Guinea. Methods: We performed a cross-sectional study between October 2020 and January 2021 in the Bata district of Equatorial Guinea. Participants aged 1–9 years, 10–17 years and above 18 were recruited. Fresh venous blood was collected for malaria testing via mRDTs and light microscopy. Stool specimens were collected, and the Kato–Katz technique was used to detect the presence of Ascaris lumbricoides, Trichuris trichiura, hookworm spp. and intestinal Schistosoma eggs. Results: A total of 402 participants were included in this study. An amount of 44.3% of them lived in urban areas, and only 51.9% of them reported having bed nets. Malaria infections were detected in 34.8% of the participants, while 50% of malaria infections were reported in children aged 10–17 years. Females had a lower prevalence of malaria (28.8%) compared with males (41.7%). Children of 1–9 years carried more gametocytes compared with other age groups. An amount of 49.3% of the participants infected with T. trichiura had malaria parasites compared with those infected with A. lumbricoides (39.6%) or both (46.8%). Conclusions: The overlapping problem of STH and malaria is neglected in Bata. The current study forces the government and other stakeholders involved in the fight against malaria and STH to consider a combined control program strategy for both parasitic infections in Equatorial Guinea.
A Review of the Application of the Soil and Water Assessment Tool (SWAT) in Karst Watersheds
Authors: Al Khoury Ibrahim , Boithias Laurie , Labat David
Published: March 2023

Karst water resources represent a primary source of freshwater supply, accounting for nearly 25% of the global population water needs. Karst aquifers have complex recharge characteristics, storage patterns, and flow dynamics. They also face a looming stress of depletion and quality degradation due to natural and anthropogenic pressures. This prompted hydrogeologists to apply innovative numerical approaches to better understand the functioning of karst watersheds and support karst water resources management. The Soil and Water Assessment Tool (SWAT) is a semi-distributed hydrological model that has been used to simulate flow and water pollutant transport, among other applications, in basins including karst watersheds. Its source code has also been modified by adding distinctive karst features and subsurface hydrology models to more accurately represent the karst aquifer discharge components. This review summarizes and discusses the findings of 75 SWAT-based studies in watersheds that are at least partially characterized by karst geology, with a primary focus on the hydrological assessment in modified SWAT models. Different karst processes were successfully implemented in SWAT, including the recharge in the epikarst, flows of the conduit and matrix systems, interbasin groundwater flow, and allogenic recharge from sinkholes and sinking streams. Nonetheless, additional improvements to the existing SWAT codes are still needed to better reproduce the heterogeneity and non-linearity of karst flow and storage mechanisms in future research.
Mutation Characteristics of Precipitation Concentration Spatiotemporal Variation and Its Potential Correlation with Low-Frequency Climate Factors in the LRB Area from 1960 to 2020
Authors: Zhang Lu , Cao Qing , Liu Kanglong
Published: March 2023

The precipitation conce ntration degree (PCD) and precipitation concentration period (PCP) in the Liaohe River basin (LRB) from 1960 to 2020 were calculated depending on the daily precipitation data derived from meteorological stations. The mutations of the PCD and PCP were identified by sliding t-test, and spatiotemporal evolution characteristics before and after the mutation point were further analyzed. Cross wavelet transform (CWT) was used to reveal the influence of four low-frequency climate factors (Pacific Decadal Oscillation (PDO), Arctic Oscillation (AO), El Niño -Southern Oscillation (ENSO), and Sunspots (SS)) on precipitation concentration. The results were presented as follows: Mutations occurred in the PCD sequence in 1980 and the PCP sequence in 2005 in the LRB. Spatial distribution of the PCD generally increased from the southeast to the northwest and tended to flatten. Over the past 60 years, the annual PCD tended to decrease, with a variation range of 0.53 to 0.80. The PCP was relatively concentrated in early July to early August, decreasing before and increasing after the mutation. Important climatic factors driving the mutation of PCD included PDO, SS, and AO. However, the resonance between climate factors and the PCD was characterized by complexity and diversity. The PCP was mainly affected by AO and SS before the mutation. ENSO had an important influence on both PCD and PCP, but had no significant correlation with mutation occurrence.

The assessment of the environmental footprint of an organization or product is based on methods published by the European Union Joint Research Centre, which take 16 impact areas into account. Among the listed categories are human and freshwater ecosystem toxicities. Standard protocols utilize just chemical parameters as input data, hindering the determination of the full impact of complex mixes, such as pollutants released into the environment. Biological assays enable us to overcome this gap: in the present work, assays were employed to determine both baseline and specific toxicity to aquatic species (green algae, luminescent bacteria, and crustacean cladocera) as well as specific toxicity (mutagenicity and carcinogenicity). Ecological footprint was estimated with regard to the impact categories “freshwater toxicity” and “human cancer toxicity” following the standard methodology. In parallel, the impact on the above categories was estimated using the results of biological assays as input. Standard and bioassay-based results are not always congruent, and conventional methods generally underestimate the effects. Likewise, the choice of reference substance (metals or organics) influences the quantification of impact. Appropriate batteries of biological assays could therefore be utilized to complement LCA (Life Cycle Assessment) techniques in order to make them more sensitive when considering toxicity in mid-term impact categories.

Authors: Seo Julianna , Seth Ishith , Dooreemeah Dilshad , Lee Chun Hin Angus
Published: March 2023

Purpose: Ileostomy volvulus is a rare cause of small bowel obstruction. We present an unusual case of ileostomy volvulus without the presence of adhesions. Additionally, a systematic literature review was performed to collate the current literature on the causes, diagnosis, treatment, and preventative measures of ileostomy-related small bowel obstruction.Methods: PubMed (MEDLINE), Embase, Google Scholar, Scopus, and CENTRAL were searched from their inception up to August 2022. This study adhered to the PRISMA guidelines and was registered on PROSPERO. The primary outcomes included patients’ demographics, imaging modality, indication for initial surgery, type and configuration of stoma, surgical treatment, and recurrence of volvulus. The quality of included studies was assessed using the Murad tool. Written informed consent was obtained from the patient.Results: Seven studies were included, comprising 967 patients. Stoma outlet obstruction (SOO) was reported in all 159 patients, and 12 had ileostomy volvulus as the cause. A majority of patients had loop ostomies for ileostomy volvulus. No complications or mortality were reported in the included studies, and half of the included studies were deemed to be of good quality.Conclusion: This case demonstrates the need for high clinical suspicion of SOO in patients with loop ileostomy, and rapid management should be undertaken. Whilst loop ileostomies, increased rectus abdominal muscle thickness, and lower preoperative total glucocorticoid dosage are associated with SOO, large-scale retrospective studies are needed to validate our findings.
Input force and floor impedance measurement for the standard tapping machine and the standard impact ball

Published: March 2023

The current ASTM and International Standards Organization (ISO) standard im- pact test method for floor-ceiling assemblies does not require the test engineer to measure the input force during the impact. A standard tapping machine or a standard impact ball is used for these tests, but
these input sources usually do not have any provision to measure the input force. In this work, the input force of these impact methods was measured on seven different assemblies, and a modal hammer was used as a “control” source. The input force and average floor impedance were
measured and compared to each other. The peak input force levels due to the tapping machine vary by approximately 38 dB from one floor to the other, and the frequency excitation bandwidth varies widely based on the type of floor construction. This shows that there is a need to measure the
input force and scale the output sound quantity with the input force to get a frequency response function (FRF)-like quantity to compare different floor-ceiling assemblies. For the impact ball, the variation in low-frequency input force levels is almost non-existent, but the impact ball has
a poor measurement signal-to-noise ratio above 80 Hz one-third octave band. The impedance measured using the impact ball matches closely with the control impedance measured using the modal hammer.

The purpose of this research is to examine and analyze the legal rules regarding Syahbandar in Indonesian laws and regulations; the role played by Syahbandar Belawan and its obstacles in carrying out sea transportation safety. The method used is normative juridical research by analyzing laws and regulations and conceptual analysis by analyzing descriptive data. The results of the study show that the Syahbandar regulations are regulated in Law 17 of 2008 concerning shipping, Minister of Transportation Regulation No. 34 of 2012, Minister of Transportation Regulation No. 36 of 2012, and RI Government Regulation No. 9 of 2019. The future role of Syahbandar must be as the front guard in identifying cases of ship accidents at sea and must be able to change himself in a more professional direction and must routinely carry out ship inspections so that accidents during shipping can be minimized. The obstacles faced by Syahbandar in carrying out sea transportation safety supervision can be seen from a regulatory perspective, from an agency perspective, and from a facilities and infrastructure perspective. Suggestions that can be drawn from this thesis are that Belawan Syahbandar officers should provide educational supplies and train their employees to increase knowledge and skills that support supervisory activities, so that they can run properly so that the supervisory function of shipping safety can be improved.

Analysis of Production Technology and Distribution Patterns of Pottery Excavated from the Hwacheon Woncheon-ri Site
Authors:   The hoseo Archaeological Society, Cho Daeyoun , Sim Jaeyoaun
Published: March 2023

In this paper, a series of scientific analyses were conducted on Baekje pottery excavated from the Hwacheon Woncheon-ri site in order to explore the possibility of distribution of pottery which was produced in the central area of Baekje to this site, as well as to identify the nature of the production technology at this site. To this end, Baekje ceramic samples excavated from the site of Woncheon-ri, Hwacheon were selected. In addition, ceramic samples from the Gyeongdang District of Pungnab Fortress were also selected and analyzed as contemporaneous, comparable artifacts. In order to increase the resolution of the provenance study, Ceramic Petrography and Instrumental Neutron Activation Analysis were adopted. As a result, it could be identified that utilitarian pottery and prestige pottery from the Woncheon-ri site in Hwacheon shared common attributes in terms of the raw material that was used. This result strongly suggests that at least some of the vessels had been produced by the same production group or community. In addition, prestige ceramics excavated from the Woncheon-ri site illustrate a pattern of separation from the prestige ceramics of Pungnab Fortress, which suggests that the prestige pottery of the Baekje center may not have been distributed to the Hwacheon area during this period. In other words, it appears likely that the production community of prestige pottery may have operated within or around the Hwacheon area at the time.

This study set out to to make an approach to the differences and changes of burial system including royal tombs and noble tombs among the ancient tombs distributed around the Woongjin and Sabi capital city by comparing them in the distribution pattern, the construction order among the individual tombs, and the structure of tomb.
During the Woongjin and Sabi period, Baekje's ancient tombs followed the natural landform with royal and noble tombs built closer to the capital in general. Unlike the Woongjin period, the Sabi period witnessed the further systemization of tomb arrangement, which is due to the hierarchy of tomb and the clear regulations involved in tomb construction. The royal and noble tombs built around the capital city of Baekje during the Woongjin and Sabi period were categorized based on the structure of tomb according to the stage(late 5th century), when the mainstream was stone chamber tomb with a vaulted ceiling of a square or rectangular form, the stage(early and middle 6th century), when brick chamber tomb of an rectangular form appeared and had impacts on stone chamber tomb, and the stage(since the late 6th century), when stone chamber tomb of a narrow rectangular form become mainstream. These changes of burial system throughout the stages were respectively influenced by the attempted revival of Baekje through the introduction of the brick chamber tomb from the Southern Dynasties of China in the latter part of the Woongjin period, the appearance of an institutionalized capital and burial system following transfer of the new Sabi capital city on its extension, and the ordering of official ranks and the pursuit of practicality according to the progress of institutionalization after the transfer of Sabi capital.

In social research, respondents are usually given several questions or indicators for assessment. Responses between respondents may differ even if the same questions or indicators are given. This is one of the causes of the diversity of responses. The diversity of responses is one of the factors that cause response bias in conducting social research. The diversity of responses can come from differences in the thought processes of each respondent. There are three main aspects in the thought process, namely cognition, affection, and conation. This paper aims to analyze the source of the diversity of responses in the aspects of cognition, affection, and conation. The first thing to do in this research is to design a questionnaire by developing indicators into three aspects (cognition, affection, and conation). The study involved 100 respondents using OVO with a purposive sampling method. Respondents assess indicators of aspects of cognition, affection, and conation. The assessment options given are discrete assessments 1-5 with a description of the assessment adjusted to the indicators. Then, the respondent's assessment data were analyzed by calculating the standard deviation, analysis of variance, further test (Tukey HSD) and the distribution of the assessment of each indicator. The main result obtained is that there are three consecutive indicators with the largest standard deviation values in each aspect. These indicators are the source of the diversity of responses in aspects of cognition, affection, and conation. The results of the analysis also show that the conation aspect is the most diverse aspect with the largest standard deviation value. This research is useful as a reference for making social research questionnaires in measuring aspects related to cognition, affection, and conation.
Model ETAS Spatio-Temporal pada Analisis Pemetaan Intensitas Kegempaan di Wilayah Sumatera
Authors: Wijaya Andreas Rony
Published: March 2023

High seismic activity forces Indonesia to mitigate natural disasters to minimize the impact of these disasters. One of the mitigation efforts that can be done is to know the possibility of an earthquake occurring in an area. Earthquakes, which are random phenomena, cannot be determined with certainty. Therefore, studies in seismological statistics can be used. One of the studies in seismological statistics that discusses the occurrence of earthquakes is the epidemic-type aftershock sequence (ETAS) model. This model describes the main seismic activity followed by aftershocks. The ETAS model, which only considers the parameters of time and event magnitude, was developed into a Spatio-temporal ETAS model, which also describes spatial parameters or locations. This study used the Spatio-temporal ETAS model to analyze the Sumatra region’s seismic activity from 2000-2022. Earthquake data sources are obtained from the United State Geological Survey (USGS). Based on data analysis, the Spatio-temporal ETAS model expressed in terms of the conditional intensity function shows that earthquakes that occur in the Sumatera region with a large magnitude tend to produce a large conditional intensity function as well. The spatial component of the spatio-temporal ETAS model can be explained by mapping the peak ground acceleration (PGA). The results of the PGA mapping show that seismic activity in the Sumatera region is prone to occur along the north and west coasts of the Sumatra region, with PGA values ranging from 0.2 g to 0.9 g. The larger the PGA value means, the higher the risk of an earthquake occurring in the area marked with a reddish-yellow dot or contour.

El proceso de formación del alocutivo vasco
Authors: Domene Verdú José Fernando
Published: March 2023

Las estructuras tricasuales alocutivas de la lengua vasca se caracterizan por los sufijos -k y -n, que indican el masculino y el femenino respectivamente, y por el infijo -i-, que indica que esos dos sufijos expresan el caso alocutivo. Sin embargo, esos afijos no se han añadido simultáneamente y su distribución dialectal refleja el proceso diacrónico en el que se añadieron. Las estructuras tricasuales alocutivas se han formado al añadirle a las no alocutivas los sufijos de 2ª persona singular masculino y femenino, -k y -n, y esta estructura antigua se ha conservado en los dialectos orientales (en suletino, en el Roncal y en parte del bajo-navarro). Más tarde, se le añadió el indicador de alocutivo -i entre el prefijo...

Mathematical Model for Estimation of Volume Respiratory Parameters
Authors: Revinskaya I. I.
Published: March 2023

A mathematical model of the biomechanics of human respiration has been developed. To verify the proposed mathematical model, it is suggested to use a photo-optical method for recording the biomechanics of the chest and abdomen together with spirometry. Pilot studies were carried out among 10 men aged 20–22. The body mass index of the subjects ranged from 19.3 to 21.5 kg/m², height – from 169 to 182 cm, weight – from 55 to 70 kg. Correlation-regression analysis of the results showed a strong relationship between biomechanical movements of the chest and abdominal walls and changes in the diameters of the airways during continuous breathing (correlation coefficient r = 0.89, statistically significant test result p ≤ 0.05). The proposed mathematical model can be used for indirect estimation of lung volume.
