In this study, we analyzed the C, N, and P contents and stoichiometric characteristics of forage leaves of five species (Elymus breviaristatus cv. Tongde, Poa crymophila cv. Qinghai, Puccinellia tenuiflora cv. Qinghai, Festuca sinensis cv. Qinghai, and Poa pratensis cv. Qinghai) in “fertilizer-reconstructed soil” through integrative soil amendment with parched sheep manure and granular organic fertilizer in an alpine mining area. A model is fitted in order to screen out the best forage species suitable for vegetation restoration in the alpine mining area and the most favorable fertilizer dosage to improve the nutrient content of forage leaves. The results showed that (1) increasing the dosages of granular organic fertilizer and sheep manure had little effect on the C content of the five types of forage grasses, but they could significantly increase the N and P contents and N/P of the manually restored grassland in the alpine mining area (p < 0.05). (2) The productivity and stability of the five species were ranked as follows: Elymus breviaristatus cv. Tongde > Puccinellia tenuiflora cv. Qinghai > Festuca sinensis cv. Qinghai > Poa pratensis cv. Qinghai > Poa crymophila cv. Qinghai. (3) According to the fitted least squares model and the willingness to maximize the C, N, and P contents of the leaves, the ranking of the five forage grasses was described by the Prediction Profiler as follows: Elymus breviaristatus cv. Tongde > Puccinellia tenuiflora cv. Qinghai > Festuca sinensis cv. Qinghai > Poa crymophila cv. Qinghai > Poa pratensis cv. Qinghai. (4) The predictive model suggested that the optimal contents of C, N, and P in Elymus breviaristatus cv. Tongde, Festuca sinensis cv. Qinghai, and Poa pratensis cv. Qinghai leaves could be achieved with the application of 3.6 kg/m2 of granular organic fertilizer and 45.0 kg/m2 of sheep manure. For Poa crymophila cv. Qinghai leaves, the ideal content was attained by applying 0 kg/m2 of granular organic fertilizer and 45.0 kg/m2 of sheep manure. Lastly, the optimal C, N, and P contents in Puccinellia tenuiflora cv. Qinghai leaves could be obtained through the application of 3.6 kg/m2 of granular organic fertilizer combined with 0 kg/m2 of sheep manure. In conclusion, the study’s results highlight the significant practical value of the fertilizer-reconstructed soil for vegetation restoration in alpine mining regions.

Published: November 2023

In this article, we investigated the dust deposit on leaves in the vegetation period of urban trees using a simple washing method. The data presented in this paper are preliminary results. Air pollution and the area and population of cities are increasing. The EU directives require the reduction and maintenance of air pollution. Trees have many ecological services, including the dust removal capacity. We investigated four urban tree species (Acer platanoides L., Fraxinus excelsior L., Tilia tomentosa Moench., and Prunus cerasifera L. ‘Woodii’) in many locations in Budapest. After collection, the leaves were washed with distillated water, which was eliminated in a drying chamber, and then the dust was measured back into the beakers. Microscopical photos were taken of each leaf’s surface. We found differences among species and seasons, which confirmed previous studies. Examining the data by location, we found no difference in dust deposition, unlike previous results. The dust deposition for Tilia tomentosa Moench. is between 48 and 295 mg/m2; for Fraxinus excelsior L., between 47 and 205 mg/m2; and for Acer platanoides L., between 110 and 500 mg/m2. No relevant data were found for Prunus cerasifera ‘Woodii’ (between 426 and 492 mg/m2) due to its exposed location. New data were obtained in Budapest for the dust deposition of the ‘Woodii’ variety. We partially confirmed or provided new results by examining the dust deposition capacities of urban trees. The leaf surface structure of the examined trees is supposedly a typical cause of dust deposit differences.
Heidegger’s Existential Diagnosis and Bonaventure’s Positive Existential Remedy: Using Hermeneutics to Address the Problem of Anxiety over Intellectual Finitude
Authors: Lo Jonathan Chung-Yan
Published: November 2023

In today’s postcritical environment, the philosophical disciplines have at times acquired a negative reputation for abstraction, relativity and impracticability. While indispensable to the modern university curriculum, the meaning and utility of the philosophical enterprise continues to register ambivalently in modern popular consciousness. In this article, I challenge this popular assumption with a case study in philosophical interpretation, by applying the hermeneutics of German existentialist Martin Heidegger (1889–1976) to issues of practical religious life. Within a life-context of anxiety over intellectual finitude and its ensuing projections, I demonstrate how the innovative sapiential reading of Christ by medieval Franciscan theologian Bonaventure of Bagnoregio (c. 1217–1274) supplies a productive intervention to ensure a new state-of-mind. This new state-of-mind arising from a new mode of understanding and being-in-the-world, amounts to a transmutation of the Heideggerian hermeneutic mode in the light of biblical truth. Bonaventure’s threefold way of Christological exegesis serves as a requisite framework in which to practically redeploy the Heideggerian way of understanding towards a positive existential end.

Published: November 2023

Isometric strength testing using a digital dynamometer is reliable for muscle function evaluation. It allows us to objectify manual strength assessment measurement. We tested intra- and inter-observer reliability of a user-friendly efficient digital dynamometer—the Forcemeter—equipped with a computer program to monitor the measurements and to store the data. Abduction, forward flexion, and external and internal rotation of both shoulders were tested three times in 20 healthy volunteers with no record of shoulder trauma. Isometric contracture was recorded in newtons. The first and the third test were carried out by Examiner A (intra-rater reliability); the second test, by Examiner B (inter-rater reliability). Good reliability was shown for intra-class correlation coefficient (ICC) values which mean moderate to high correlations (r = 0.66–0.93) for both examiners. Moderate to high correlations (r = 0.72–0.91) were found for comparisons between the results obtained by Examiner A.

Published: November 2023

The leaf area index (LAI) played a crucial role in ecological, hydrological, and climate models. The normalized difference vegetation index (NDVI) has been a widely used tool for LAI estimation. However, the NDVI quickly saturates in dense vegetation and is susceptible to soil background interference in sparse vegetation. We proposed a multi-angular NDVI (MAVI) to enhance LAI estimation using tower-based multi-angular observations, aiming to minimize the interference of soil background and saturation effects. Our methodology involved collecting continuous tower-based multi-angular reflectance and the LAI over a three-year period in maize cropland. Then we proposed the MAVI based on an analysis of how canopy reflectance varies with solar zenith angle (SZA). Finally, we quantitatively evaluated the MAVI’s performance in LAI retrieval by comparing it to eight other vegetation indices (VIs). Statistical tests revealed that the MAVI exhibited an improved curvilinear relationship with the LAI when the NDVI is corrected using multi-angular observations (R2 = 0.945, RMSE = 0.345, rRMSE = 0.147). Furthermore, the MAVI-based model effectively mitigated soil background effects in sparse vegetation (R2 = 0.934, RMSE = 0.155, rRMSE = 0.157). Our findings demonstrated the utility of tower-based multi-angular spectral observations in LAI retrieval, having the potential to provide continuous data for validating space-borne LAI products. This research significantly expanded the potential applications of multi-angular observations.

Published: November 2023

As a pivotal integral component within electronic systems, analog circuits are of paramount importance for the timely detection and precise diagnosis of their faults. However, the objective reality of limited fault samples in operational devices with analog circuitry poses challenges to the direct applicability of existing diagnostic methods. This study proposes an innovative approach for fault diagnosis in analog circuits by integrating deep convolutional generative adversarial networks (DCGANs) with the Transformer architecture, addressing the problem of insufficient fault samples affecting diagnostic performance. Firstly, the employment of the continuous wavelet transform in combination with Morlet wavelet basis functions serves as a means to derive time–frequency images, enhancing fault feature recognition while converting time-domain signals into time–frequency representations. Furthermore, the augmentation of datasets utilizing deep convolutional GANs is employed to generate synthetic time–frequency signals from existing fault data. The Transformer-based fault diagnosis model was trained using a mixture of original signals and generated signals, and the model was subsequently tested. Through experiments involving single and multiple fault scenarios in three simulated circuits, a comparative analysis of the proposed approach was conducted with a number of established benchmark methods, and its effectiveness in various scenarios was evaluated. In addition, the ability of the proposed fault diagnosis technique was investigated in the presence of limited fault data samples. The outcome reveals that the proposed diagnostic method exhibits a consistently high overall accuracy of over 96% in diverse test scenarios. Moreover, it delivers satisfactory performance even when real sample sizes are as small as 150 instances in various fault categories.

Thousand-grain weight is the main parameter for accurately estimating rice yields, and it is an important indicator for variety breeding and cultivation management. The accurate detection and counting of rice grains is an important prerequisite for thousand-grain weight measurements. However, because rice grains are small targets with high overall similarity and different degrees of adhesion, there are still considerable challenges preventing the accurate detection and counting of rice grains during thousand-grain weight measurements. A deep learning model based on a transformer encoder and coordinate attention module was, therefore, designed for detecting and counting rice grains, and named TCLE-YOLO in which YOLOv5 was used as the backbone network. Specifically, to improve the feature representation of the model for small target regions, a coordinate attention (CA) module was introduced into the backbone module of YOLOv5. In addition, another detection head for small targets was designed based on a low-level, high-resolution feature map, and the transformer encoder was applied to the neck module to expand the receptive field of the network and enhance the extraction of key feature of detected targets. This enabled our additional detection head to be more sensitive to rice grains, especially heavily adhesive grains. Finally, EIoU loss was used to further improve accuracy. The experimental results show that, when applied to the self-built rice grain dataset, the precision, recall, and mAP@0.5 of the TCLE–YOLO model were 99.20%, 99.10%, and 99.20%, respectively. Compared with several state-of-the-art models, the proposed TCLE–YOLO model achieves better detection performance. In summary, the rice grain detection method built in this study is suitable for rice grain recognition and counting, and it can provide guidance for accurate thousand-grain weight measurements and the effective evaluation of rice breeding.
Can IR Images of the Water Surface Be Used to Quantify the Energy Spectrum and the Turbulent Kinetic Energy Dissipation Rate?
Authors: Metoyer Shelby L. , Bogucki Darek J.
Published: November 2023

Near-surface oceanic turbulence plays an important role in the exchange of mass, momentum, and energy between the atmosphere and the ocean. The climate modifying the air–sea CO2 transfer rate varies linearly with the surface turbulent kinetic energy dissipation rate to the 1/4 power in a range of systems with different types of forcing, such as coastal oceans, river estuaries, large tidal freshwater rivers, and oceans. In the first part of this paper, we present a numerical study of the near-surface turbulent kinetic energy spectra deduced from a direct numerical simulation (DNS) compared to turbulent kinetic energy spectra deduced from idealized infrared (IR) images. The DNS temperature fields served as a surrogate for IR images from which we have calculated the underlying kinetic energy spectra. Despite the near-surface flow region being highly anisotropic, we demonstrated that modeled isotropic and homogeneous turbulence spectra can serve as an approximation to observed near-surface spectra within the inertial and dissipation ranges. The second part of this paper validates our numerical observations in a laboratory experiment. In this experiment, we compared the turbulent kinetic energy spectra near the surface, as measured using a submerged shear sensor with the spectra derived from infrared images collected from above the surface. The energy dissipation measured by the shear sensor was found to be within 20% of the dissipation value derived from the IR images. Numerically and experimentally, we have demonstrated that IR-based and remote measurement techniques of the aquatic near surface offer a potentially accurate and non-invasive way to measure near-surface turbulence, which is needed by the community to improve models of oceanic air–sea heat, momentum, and gas fluxes.

Evaluating the efficiency of surface treatments is a problem of paramount importance for the cork stopper industry. Generically, these treatments create coatings that aim to enhance the impermeability and lubrification of cork stoppers. Yet, current methods of surface analysis are typically time-consuming, destructive, have poor representativity or rely on indirect approaches. In this work, the use of a laser-induced breakdown spectroscopy (LIBS) imaging solution is explored for evaluating the presence of coating along the cylindrical surface and in depth. To test it, several cork stoppers with different shaped areas of untreated surface were analyzed by LIBS, making a rectangular grid of spots with multiple shots per spot, to try to identify the correspondent shape. Results show that this technique can detect the untreated area along with other features, such as leakage and holes, allowing for a high success rate of identification and for its performance at different depths, paving the way for future industry-grade quality control solutions with more complex surface analysis.
Debonding Detection in Grouted Sleeves Using Axisymmetric Longitudinal Guided Waves
Authors: Liu Jiahe , Li Dongsheng , Cui Xiushi
Published: November 2023

Grouted sleeves (GSs) are a type of precast joint that can effectively connect steel rebars with excellent performance. However, the grouting debonding problem, which can occur due to the leakage of the glue plug, can seriously affect the properties of GSs. In this paper, a guided-wave-based structural health monitoring (SHM) method is used to detect debonding in GSs. The axisymmetric longitudinal mode is selected as the incident wave since it is sensitive to axial damage. Eight piezoelectrics (PZTs) are then symmetrically installed to actuate signals. The proposed samples are GSs with four different debonding sizes. First, the relationship between the arrival time of the first wave packet and the debonding size is explored through theoretical derivation. The arrival time decreases linearly with an increasing debonding size. A similar trend is observed when the relationship is verified via a numerical simulation and experimental results. This method will provide a reference for detecting debonding in similar GS multilayer structures.

A Printed Dipole Array with Bidirectional Endfire Radiation for Tunnel Communication
Authors: Xu Tianfan , Xu Mengchi , Lu Haitao , Cai Xiao
Published: November 2023

Tunnel communication always suffers from path loss and multipath effects caused by surrounding walls. Meanwhile, the traditional leaky coaxial cables are expensive to deploy, inconvenient to operate, and difficult to maintain, leading to many problems in practical use. To solve the abovementioned problems, a low-profile printed dipole array operating at 3.5 GHz with bidirectional endfire radiation is designed based on the method of maximum power transmission efficiency (MMPTE). By setting two virtual test receiving dipoles at the two opposite endfire directions and then maximizing the power transmission efficiency between the printed dipole array to be designed and the test receiving antennas, the optimal amplitudes and phases for the array elements are obtained. Based on the optimal distributions of excitations, the simulation results show that the proposed eight-element printed dipole array can simultaneously generate two mirrored endfire beams towards opposite directions. Furthermore, the corresponding normalized cross-polarization levels are lower than −22.3 dBi both in the azimuth and elevation planes. The peak endfire gain is 10.7 dBi with maintenance of higher than 10 dBi from 3.23 GHz to 3.66 GHz, which is suitable for tunnel communication.
Divalent Aptamer-Functionalized Nanochannels for Facile Detection of Cancer Cell-Derived Exosomes
Authors: Huang Yue , Zhou Fangfang , Jia Fengjie , Yang Nana
Published: November 2023

Exosomes are considered potential biomarkers for early screening and accurate non-invasive diagnosis of cancer, so development of innovatively facile approaches for the detection of cancer cell-derived exosomes has become increasingly important. Herein, we propose a facile electrochemical biosensor based on divalent aptamer-functionalized nanochannels for highly efficient detection of cancer cell-derived exosomes. The aptamer against transmembrane receptor protein CD63 and the aptamer targeting membrane protein EpCAM are simultaneously immobilized on the nanochannels to construct the divalent aptamer-functionalized nanochannels. Thus, the target exosomes can be recognized and selectively captured by the functionalized nanochannels in a divalent collaborative manner. The combined exosomes overlay the ion channel effectively and hinder the ionic flow through the nanochannels, resulting in an evidently varied ionic transport behavior corresponding to the abundance of exosomes. The divalent aptamer-functionalized nanochannels can substantially promote the binding stability and enhance the detection specificity, while the sensitivity of detection is improved greatly by virtue of the amplified response of array channels synergized with the electrochemical technique. Therefore, the developed biosensor provides a highly specific, sensitive, and accurate approach for the detection of cancer cell-derived exosomes, which may hold great potential for application in early clinical cancer diagnosis.

An automotive 2.1 μm CMOS image sensor has been developed with a full-depth deep trench isolation and an advanced readout circuit technology. To achieve a high dynamic range, we employ a sub-pixel structure featuring a high conversion gain of a large photodiode and a lateral overflow of a small photodiode connected to an in-pixel storage capacitor. With the sensitivity ratio of 10, the expanded dynamic range could reach 120 dB at 85 °C by realizing a low random noise of 0.83 e- and a high overflow capacity of 210 ke-. An over 25 dB signal-to-noise ratio is achieved during HDR image synthesis by increasing the full-well capacity of the small photodiode up to 10,000 e- and suppressing the floating diffusion leakage current at 105 °C.

Published: November 2023

Low-frequency aperture arrays represent sensitive instruments to detect signals from radio astronomic sources situated in the universe. In Italy, the Sardinia Aperture Array Demonstrator (SAAD) consists of an ongoing project of the Italian National Institute for Astrophysics (INAF) aimed to install an aperture array constituted of 128 dual-polarized Vivaldi antennas at the Sardinia Radio Telescope (SRT) site. The originally envisaged 128 elements of SAAD were re-scoped to the 16 elements of its precursor named SADino, with the aim to quickly test the system with a digital beam-former based on the Italian Tile Processing Module (iTPM) digital back-end. A preliminary measurements campaign of radio frequency interference (RFI) was performed to survey the less contaminated spectral region. The results of these measurements permitted the establishment of the technical requirements for receiving a chain for the SADino telescope. In this paper, the design, implementation, and characterization of this signal acquisition chain are proposed. The operative frequency window of SAAD and its precursor, SADino, sweeps from 260 MHz to 420 MHz, which appears very attractive for radio astronomy applications and radar observation in space and surveillance awareness (SSA) activities.

Published: November 2023

The long-term sustainability of the global water supply, with a paramount emphasis on cleanliness and safety, stands as a formidable challenge in our modern era. In response to this pressing issue, adsorption techniques have emerged as pivotal and widely recognized solutions for the removal of hazardous pollutants, with a particular emphasis on lead adsorption from wastewater. This comprehensive review explores the relentless advancements made in the adsorption domain, highlighting innovations using separation and purification techniques that surpass traditional metal oxide-based adsorbents. Of particular note is the growing exploration of alternative materials, such as starch, chitosan, nanoscale structures like zeolites and metal-organic frameworks, magnetic materials, and carbon-based substances for the development of inorganic adsorbents. These materials, with their remarkable capacity for nanoscale structural adjustment, possess extraordinary capabilities for effective contaminant removal, facilitating swift water purification. The literature survey for this review was conducted using the Google Scholar engine, with “adsorbents for lead remediation” as the starting keywords, resulting in approximately 6000 papers. The search was refined to focus on the last three years and specifically targeted review papers which are most relevant to lead remediation. More than 100 papers were analysed to investigate various techniques, surface modifications, and adsorbent materials for managing inorganic pollutants in water. This review also illuminates research limitations, with a specific focus on starch-based adsorbents in lead remediation. As we progress towards practical commercial applications, this review identifies challenges associated with the development of inorganic adsorbents and provides invaluable insights into future prospects. Surface modification emerges as a promising path, with the potential to substantially enhance adsorption capacity, potentially doubling or even quadrupling it. Moreover, the adsorbents demonstrate impressive regenerative capabilities, maintaining up to 90% regeneration efficiency after multiple cycles. In conclusion, starch-based adsorbents show considerable potential as effective agents for lead purification from aquatic environments. Nevertheless, the need for further research persists, emphasizing the optimization of the adsorption process and exploring the long-term stability of starch-based adsorbents in real-world scenarios.

Introduction: Human mobility is a critical aspect of existence and survival, but may compromise care engagement among people living with HIV (PLHIV). We examined the association between various forms of human mobility with retention in HIV care and antiretroviral treatment (ART) interruptions. Methods: In a cohort of adult PLHIV in Kenya and Uganda, we collected surveys in 2016 about past 6-month travel and lifetime migration histories, including reasons and locations, and engagement in HIV care defined as (1) discontinuation of care, and (2) history of a treatment interruption among those who remained in care. We estimated associations between mobility and these care engagement outcomes via logistic regression, adjusted for sex, prior mobility, age, region, marital status, household wealth, and education. Results: Among 1081 participants, 56 (5%) reported having discontinued care; among those in care, 104 (10%) reported treatment interruption. Past-year migration was associated with a higher risk of discontinuation of care (adjusted odds ratio [aOR] 1.98, 95% CI 1.08–3.63). In sex-stratified models, the association was somewhat attenuated in women, but remained robust among men. Past-year migration was associated with reduced odds of having a treatment interruption among men (aOR 0.51, 95% CI 0.34–0.77) but not among women (aOR 2.67, 95% CI 0.78, 9.16). Travel in the past 6 months was not associated with discontinuation of care or treatment interruptions. Conclusions: We observed both negative and protective effects of recent migration on care engagement and ART use that were most pronounced among men in this cohort. Migration can break ties to ongoing care, but for men, who have more agency in the decision to migrate, may foster new care and treatment strategies. Strategies that enable health facilities to support individuals throughout the process of transferring care could alleviate the risk of care disengagement.

Los resultados de las entrevistas a las estudiantes (n 28), muestran que todas ellas manifiestan que el nivel de ocupación (desempleado, subocupado, empleado) de la población se vincula con su salud; y justifican esa aseveración a partir del impacto de las condiciones laborales en la salud de la población, refiriéndose a la calidad de vida/ necesidades básicas satisfechas que permite el acceso al trabajo, al acceso a los sistemas de salud (que en nuestro país se vincula a los subsistemas de salud) y a las características del ambiente laboral. Además, se analizó en qué situaciones consideran que una persona se encuentra afectada en su salud; las opciones más seleccionadas fueron: “malestar físico, psíquico y/o emocional”, “se altera su bienestar” y “presenta necesidades básicas insatisfechas”. Finalmente, 23 de ellas asumen que su conocimiento sobre la temática es regular, 3 consideran que es bueno y 2 insuficiente. Concluimos que el empleo se vincula con la salud, y en especial existen ocupaciones que se constituyen en población de riesgo para padecimientos fonoaudiológicos. Se considera que trabajar desde los primeros años de la formación en el marco de los determinantes sociales de la salud, constituye una herramienta fundamental para formar egresados con una mirada integral de los sujetos de atención

La telemedicina se presenta como una modalidad de trabajo clínico que creció en los últimos años en magnitud, difusión y aceptación, especialmente a partir de la pandemia por el virus SARS-CoV-2. Las publicaciones sobre el tema han aumentado en la última década y señalan que se trata de un tema de interés científico con plena actualidad. Su historia es breve: las primeras experiencias tuvieron lugar en la década del ´60 en la carrera espacial. Fundamentalmente, la telemedicina nace como una modalidad de atención no presencial aprovechando las posibilidades ofrecidas por la tecnología en contextos donde la distancia entre equipos de salud y usuarios significaba un problema. Las empresas del Complejo Médico Industrial (CMI) identifican las modalidades de telemedicina como una posibilidad de un contacto más fluido y menos regulado entre usuarios-consumidores y empresas de servicio del campo de la salud. A su vez, la necesidad de distanciamiento social para prevenir contagios entre personas en la emergencia sanitaria por el SARS-CoV-2 ofreció un contexto acorde para el desarrollo de la telemedicina. Probablemente, la pandemia estimuló la masificación abrupta de diferentes modos de atención a distancia. Sin embargo, aún no se han revisado profundamente en términos éticos y legales muchas de las formas de uso actual de la telemedicina. Se plantean interrogantes respecto de la influencia de este proceso en la profundización de la biomedicina como modelo dominante de la práctica médica actual.

Sate bandeng merupakan salah satu hidangan khas dari Provinsi Banten yang cenderung mengalami penurunan kualitas dengan cepat. Sate bandeng hanya dapat tetap segar selama sekitar 2 hari pada suhu ruangan dan 6 hari jika disimpan dalam kondisi dingin. Kendala masa simpan yang terbatas ini disebabkan oleh kandungan gizi yang tinggi dalam hidangan tersebut, serta berbagai faktor lingkungan. Oleh karena itu, dibutuhkan bahan pengawet seperti karboksimetil kitosan (KMK) agar dapat memperpanjang masa simpan sate bandeng. Penelitian ini bertujuan untuk menentukan konsentrasi optimal dari KMK yang efektif sebagai antibakteri sate bandeng terhadap bakteri Staphylococcus aureus selama masa penyimpanan dalam kondisi suhu dingin. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap Faktorial (RALF) yang melibatkan dua faktor dan dilakukan dalam dua kali ulangan. Faktor pertama melibatkan empat tingkat konsentrasi KMK, yaitu 0%, 3%, 4%, dan 5%. Sementara faktor kedua mencakup enam periode waktu penyimpanan yang berbeda, yaitu hari ke-0, 3, 6, 9, 12, dan 15. Parameter yang diuji adalah aktivitas antibakteri terhadap bakteri Staphylococcus aureus, Angka Lempeng Total (ALT) dan uji proksimat pada perlakuan terbaik. Penting untuk dicatat bahwa sampel sate bandeng yang digunakan dalam penelitian ini tidak mencakup seluruh sate bandeng dari Provinsi Banten. Sampel diambil dari salah satu Usaha Mikro, Kecil, dan Menengah (UMKM) dengan tingkat kepatuhan sanitasi yang tidak memenuhi Standar Operasional Prosedur (SOP). Hasil penelitian disajikan dalam bentuk tabel dan dijelaskan secara deskriptif. Hasil penelitian menunjukkan bahwa penambahan karboksimetil kitosan (KMK) memiliki dampak terhadap aktivitas antibakteri sate bandeng, dengan konsentrasi optimal KMK terletak pada 5%.
ОБГРУНТУВАННЯ ДЕВІАЦІЇ ТЕМПЕРАТУРИ ТЕПЛОНОСІЯ НА ВИХОДІ З СВЕРДЛОВИНИ ГЕОТЕРМАЛЬНОЇ ТЕПЛОНАСОСНОЇ СИСТЕМИ ОСОБЛИВІСТЮ ГІДРОГЕОТЕРМІЧНОГО РЕЖИМУ ЗОВНІШНЬОЇ ОБОЛОНКИ ЗЕМЛІ

В роботі наведено результати теоретичних та експериментальних досліджень щодо обґрунтування місця розташування свердловин гідротермальної теплонасосної системи для стабільного та ефективного отримання низькопотенційної геотермальної енергії. Доведено, що найбільш ефективними є теплонасосні системи які використовують теплоту ґрунту або ґрунтових вод та мають теплообмінники та свердловини встановлені на глибину нижче нейтрального шару. Наведено ендогенні та екзогенні фактори, що впливають на глибину залягання нейтрального шару. Визначено, що екзогенні фактори в порівнянні з ендогенними мають більший вплив на формування термічного режиму гідросфери. Наведено загальні закономірності зміни термічного режиму гідросфери що перебуває під впливом екзогенних факторів. Обґрунтовано, що в залежності від гідрогеологічних умов, зони розташування свердловин геотермальної теплонасосної системи, нижче теоретично визначеної глибини нейтрального шару можуть повторно утворюватися зони з суттєвою девіацією температури ґрунту. Визначені критерії що визначають тип гідрогеотермічного режиму та наведено класифікацію типів гідрогеотермічного режиму. Представлено розроблену і сконструйовану в Інституті відновлюваної енергетики НАН України експериментальну теплонасосну систему, яка складається з теплового насосу та двох свердловин, через які забезпечується циркуляція води від підземного горизонту до теплового насосу. В свердловині та на поверхні встановлені температурні датчики. Розроблено методику проведення досліджень. Наведено результати експериментальних досліджень на підставі яких встановлено, що за рахунок особливих геоморфологічних умов ділянки розташування системи, температура води в водоносному горизонті (на глибині 50 м) залежить від температури повітря та інтенсивності сонячної інсоляції протягом дня. Доведено, що між водоносним горизонтом розкритим свердловинами та розташованими рядом ставками в балках є гідравлічний зв'язок, а незначна відстань між ними та особливий рельєф місцевості впливають на зміну температури води в свердловині глибиною 50 м. Викладено основні закономірності впливу поверхневих гармонійних змін температури на режим температури зовнішньої оболонки Землі. Наведена класифікація в якій враховуються усі можливі основні типи гідрогеотермічного режиму. Отримані в ході дослідження результати мають важливе наукове і прикладне значення при проектуванні геотермальних та гідротермальних теплонасосних систем. Крім того мають перспективу подальші дослідження можливостей та ефективності використання водоносного горизонту як природного акумулятора теплоти для стабільної генерації енергії від відновлюваних джерел незалежно від кліматичних умов і пори року.

Стаття присвячена визначенню основних складових системи публічного управління соціальним розвитком міста. У дослідженні зазначається, що особливим питанням сьогодення є наявність шляхів підвищення рівня життя населення сучасних міст, що можна визначити на основі ефективного функціонування складових системи державного управління суспільним розвитком міст. У статті розглянуто механізми публічного управління як основні складові системи публічного управління соціальним розвитком міста. З урахуванням досліджень зарубіжних та вітчизняних науковців доведено першочергову домінуючу роль суспільного розвитку в сучасній системі економічних відносин. Визначено, що механізми управління описаною системою включають в себе політичні, правові, організаційні та економічні складові. У роботі розкрито основні умови ефективного функціонування зазначених механізмів: для політичного механізму це принципи добробуту, справедливості, безпеки, принцип системного впливу; для правових – це забезпечення нормативно-правових умов для підвищення якості життя мешканців міста та забезпечення їх соціального благополуччя; для організаційного – це створення та зміцнення організаційного потенціалу суб’єктів управління як важливої складової зазначеної системи; для економічного механізму ефективність можна оцінити за відповідними показниками. У статті стверджується, що оцінка ефективності досліджуваних механізмів соціального розвитку міста може здійснюватися за допомогою різноманітних показників та аналітичних методів, які враховують специфіку конкретного міста та його цілі. При чому ефективність функціонування механізмів визначається за критеріями якості життя та рівня життя населення міста.
