Acinetobacter baumannii (Ab) is an opportunistic Gram-negative pathogen intrinsically resistant to many antimicrobials. The aim of this retrospective study was to describe the imaging features on chest X-ray (CXR) and computed tomography (CT) scans in hospitalized patients with multidrug-resistant (MDR) Ab pneumonia. CXR and CT findings were graded on a three-point scale: 1 represents normal attenuation, 2 represents ground-glass attenuation, and 3 represents consolidation. For each lung zone, with a total of six lung zones in each patient, the extent of disease was graded using a five-point scale: 0, no involvement; 1, involving 25% of the zone; 2, 25–50%; 3, 50–75%; and 4, involving >75% of the zone. Points from all zones were added for a final total cumulative score ranging from 0 to 72. Among 94 patients who tested positive for MDR Ab and underwent CXR (males 52.9%, females 47.1%; mean age 64.2 years; range 1–90 years), 68 patients underwent both CXR and chest CT examinations. The percentage of patients with a positive CT score was significantly higher than that obtained on CXR (67.65% > 35.94%, p-value = 0.00258). CT score (21.88 ± 15.77) was significantly (p-value = 0.0014) higher than CXR score (15.06 ± 18.29). CXR and CT revealed prevalent bilateral abnormal findings mainly located in the inferior and middle zones of the lungs. They primarily consisted of peripheral ground-glass opacities and consolidations which predominated on CXR and CT, respectively.

Published: June 2022

The development of sensitive, non-invasive tests for the detection of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) antigens is imperative, and it is still challenging to manage the extent of infection throughout the population. Here, we designed and optimized a sandwich enzyme-linked immunosorbent assay (ELISA) protocol for SARS-CoV-2 S1 antigen detection in saliva. Both saliva samples and nasopharyngeal swabs were collected from 220 real-time quantitative polymerase chain reaction (RT-qPCR)-confirmed positive and negative cases. S1 protein receptor-binding domain (RBD) nanobodies were efficiently conjugated with 40 nm gold nanoparticles (AuNPs) and employed as antigen detection probes in the developed system, while recombinant S1 monoclonal antibodies (S1mAbs) were employed as antigen capture probes. After checkerboard assays and system optimization, the clinical samples were tested. In saliva, the developed ELISA system showed the highest sensitivity (93.3) for samples with cycle threshold (Ct) values ≤ 30; interestingly, high sensitivity (87.5 and 86%) was also achieved for samples with Ct values ≤ 35 and ≤40, respectively, compared with 90, 80 and 88% sensitivity rates for nasopharyngeal swabs with the same categorized Ct values. However, the specificity was 100%, and no cross-reactions were detected with Middle East respiratory syndrome coronavirus (MERS-CoV) or SARS-CoV antigens. These results reveal that our protocol could be established as an efficient and sensitive, non-invasive diagnostic tool for the early detection of SARS-CoV-2 infection using easily collectable saliva samples.
Experimental Studies on the Influence of Negatively Buoyant Jets on Flow Distribution in a 135-Degree Open Channel Bend
Authors: Wang Xueming , Rennie Colin D. , Mohammadian Abdolmajid
Published: June 2022

The present paper aims to investigate the evolution of velocity fields as well as secondary flows in an open channel bend under the influence of negatively buoyant jets. A 135-degree open channel bend was used for experiments, and the jet nozzle was located along the outer bank in the straight section upstream of the bend. Efforts were made to specify the flow structures with high precision measurements of three-dimensional velocities by means of a three-dimensional PIV (Particle Image Velocimetry) technology. The experimental results show that the jets comparatively affect the flow structure at the beginning and exit of the flow in a bend. Although the jets had little effect on the maximum streamwise velocity, complex secondary flow patterns and properties were found to be influenced due to the occurrence of the negatively buoyant jets in the bend.

Authors: Moon Juhwan , Lee Jaejoon , Lee Sangwon , Yun Hongsik
Published: June 2022

This study outlines the preliminary stages of the development of an algorithm to predict the optimal WQ of the Hwanggujicheon Stream. In the first stages, we used the AdaBoost algorithm model to predict the state of WQ, using data from the open artificial intelligence (AI) hub. The AdaBoost algorithm has excellent predictive performance and model suitability and was selected for random forest and gradient boosting (GB)-based boosting models. To predict the optimized WQ, we selected pH, SS, water temperature, total nitrogen(TN), dissolved total phosphorus(DTP), NH3-N, chemical oxygen demand (COD), dissolved total nitrogen (DTN), and NO3-N as the input variables of the AdaBoost model. Dissolved oxygen (DO) was used as the target variable. Third, an algorithm showing excellent predictive power was selected by analyzing the prediction accuracy according to the input variable by using the random forest or GB series algorithm in the initial model. Finally, the performance evaluation of the ultimately developed predictive model demonstrated that RMS was 0.015, MAE was 0.009, and R2 was 0.912. The coefficient of the variation of the root mean square error (CVRMSE) was 17.404. R2 0.912 and CVRMSE were 17.404, indicating that the predictive model developed meets the criteria of ASHRAE Guideline 14. It is imperative that government and administrative agencies have access to effective tools to assess WQ and pollution levels in their local bodies of water.
Copepod Diel Vertical Distribution in the Open Southern Adriatic Sea (NE Mediterranean) under Two Different Environmental Conditions
Authors: Hure Marijana , Batistić Mirna , Garić Rade
Published: June 2022

Diel vertical migration of the copepod the community was investigated in the open South Adriatic, in June 2020 and February 2021, under two very different hydrographical conditions. The influence of a winter wind-induced mixing event on copepod vertical migration at the species level was determined for the first time and compared to the situation in June when pronounced thermal stratification was observed. The samples were collected during a 24 h cycle in four depth layers from the surface down to 300 m depth, using a Nansen opening–closing net with 250-µm mesh size. In winter, the bulk of the copepod population remained in the epipelagic zone (0–100 m) over the entire 24 h cycle, with calanoids remaining the dominant group. An increasing trend of copepod standing stocks from midnight to early morning in the surface layer found in June is in agreement with previous records of copepod day–night variations in the Mediterranean Sea. Day–night differences in diversity and the number of taxa of the epipelagic area were more pronounced in June, confirming the higher intensity of diel vertical migration in summer. Although the epipelagic community was composed of numerous weak diel vertical migrant species, for the majority of investigated copepod taxa, migration patterns differed between the environmentally contrasting seasons. A multivariate non-metric analysis showed that the copepod community was strongly affected by temperature, thus exhibiting a clear seasonal structure.

Published: June 2022

In addition to agriculture, the water–land nexus (WLN) also profoundly affects the sustainable development of industry and residents’ lives. However, little research has been designed to assess the water–land nexus from the perspective of industry development and people’s quality of life. In the current paper, Wi, a regional industrial water–land nexus matching index, and Wd, a matching index of the domestic water–land nexus, were proposed for evaluating the water–land nexus from the industry development and quality of life perspectives separately in the current paper. Furthermore, climate change and human activities have significant impacts on the water–land nexus. The WLNs were assessed spatially and temporally for the first time based on these two indexes in 128 municipalities in the Huang-Huai-Hai River Basin of China from 1951 to 2017 to analyze the impacts of the changing environment on them. The impact of changing environment was explored based on changes of some climate factors and land use. The value of Wi are higher in the eastern and southern cities than the western and northern cities, while Zhenjiang city in Jiangsu Province has the highest Wi. For Wd, there are two low Wd zones across the basin, while the minimum values occurred in Linxia Hui Autonomous Region (Wd = 35.34 mm). Wi and Wd in most cities in the basin showed a significant downward trend, and some cities in the southwest of the basin have the fastest-decreasing of Wd. Wt and Wa were also calculated to assess the total and agricultural water–land nexus separately based on existing research. The Wt for the Huang-Huai-Hai River Basin gradually increases from northwest to southeast, and its spatial distribution characteristics are similar to precipitation in the river basin. In addition, the government should simultaneously implement water transfer plans to reduce the agricultural water pressure in Ningxia and Gansu provinces. Dynamic driving factors of change of the four assessment indexes (Wt, Wa, Wi, Wd) are briefly analyzed in the end of the paper.

Published: June 2022

The real-time monitoring of the vertical force of the tire is the basis for ensuring the driving safety, handling stability, fuel economy and the riding comfort of the vehicle. An algorithm for the vertical force of the tire estimation based on the combination of intelligent tire technology and neural network theory is herein proposed. Firstly, the finite element model of the 205/55/R16 radial tire was established by ABAQUS and the validity of the finite element model was verified through static experiment and dynamic experiment. Secondly, the effects of inflation pressure, speed, load and tread wear on the tire contact patch length and the radial displacement at the virtual acceleration sensor were analyzed based on the finite element analysis method and control variable method. Finally, three kinds of the vertical force prediction algorithms based on the GA-BP neural network algorithm were established, and the network performance of each prediction model was tested. The results show that the vertical force prediction model with inflation pressure and the peak value of radial displacement as the characteristic input parameters has the highest prediction accuracy and the shortest calculation time. At the same time, the mathematical formula of the Model 3 was built.

The current study tries to investigate approaches to communication, including dysphemism and euphemisms in political cartoons. Free expression of public opinion and personal, political cartoon humor and got an essential part of the information and data arena. That makes the political cartoons genre more related and remarkable than before. This given cartoon comprises visual and verbal components, making the selection of communication means in the text particularly challenging. That defines the problem of our survey. The paper has investigated political cartoons published in the USA media. Making use of the content analysis method, we chose 174 dysphemisms and euphemisms, split into lexical-semantic classifications. As a consequence, euphemisms are utilized more commonly in political cartoon than dysphemisms, which stemmed from the genre specificity; hence, the ironic impact is attained by the contrast between the visual and verbal components.

This study examines the legal laws and regulation of labor relationships, splitting states into 2 classifications. The initial incorporates Germany, Russia, France, and several other European nations. In the next - the USA, Australia, Great Britain, and other nations of the Anglo-Saxon legal systems. The comparative examination of various states’ legislation and formal-logical and functional methods are used to gratify the study’s objectives. The conclusion is made that the borrowing of the experience of the nations’ adhering to the Anglo-Saxon pattern is not acceptable for Russia because, in them, the contract of labor is demonstrated not as a means able to guarantee the workers’ rights but as a legal means to generate circumstances able to infringe on their benefits.

Published: June 2022

Highly sensitive flexible pressure sensors play an important role to ensure the safety and friendliness during the human-robot interaction process. Microengineering the active layer has been shown to improve performance of pressure sensors. However, the current structural strategy almost relying on axial compression deformation suffers structural stiffening, and together with the limited area growth efficiency of conformal interface, essentially limiting the maximum sensitivity. Here, inspired by the interface contact behavior of gecko’s feet, we design a slant hierarchical microstructure to act as an electrode contacting with an ionic gel layer, fundamentally eliminating the pressure resistance and maximizing functional interface expansion to achieving ultrasensitive sensitivity. Such a structuring strategy dramatically improves the relative capacitance change both in the low- and high-pressure region, thereby boosting the sensitivity up to 36000 kPa-1and effective measurement range up to 300 kPa. To verify the advantages of high sensitivity, the sensor is integrated with a soft magnetic robot to demonstrate a biomimetic Venus flytrap. The ability to perceive weak stimuli allows the sensor to be used as a sensory and feedback window, realizing the capture of small live insects and the transportation of fragile objects.
Transhümanizmde Adaleti Tesisin İmkanına İlişkin Bir Değerlendirme
Authors: Umut Tuba Nur , Yeşilkaya Nazan
Published: June 2022

Modern sonrası dönemde evrim teorisi, insanı gelişim aşamasında ortaya çıkan formlardan bir forma indirgerken teknoloji, insanı “geliştirmeye açık” manipülasyon nesnesi kılmış, böylelikle rasyonel süjenin özel konumu sarsılmıştır. Anti-özcü yaklaşımlarda insan ile insan üretimi teknoloji arasındaki sınırların bulanıklaştığına dair düşünceler felsefi gündemde yer bulmuştur. Yeni teknolojilerin mümkün kıldığı transhümanist hareket, evrim sürecindeki insanın teknolojik müdahale ile geliştirilmesine ve insan olmanın ötesine giden yeni bir anlayışa kapı aralamıştır. Fakat transhümanizm, ortaya koyduğu ideallerin ahlaki sonuçlarına ilişkin yeterli bir soruşturmaya girişmemektedir. Bu çalışmada gelişen insan tasavvuru ile transhümanist düşüncede yapılan felsefi ve ahlâki değerlendirmeler arasındaki boşluklara dikkat çekilecek olup söz konusu düşüncenin hazırlıksız olduğu postmodern durumda bu tasavvurların bizleri belli erdemler açısından hususen adalet açısından karşı karşıya bırakacağı sorunlara genel itibariyle işaret edilmiştir. Makalede özellikle Ray Kurzweil, John Harris, Nick Bostrom gibi çağdaş düşünürlerce ortaya koyulan transhümanist söylemin adil bir toplum ideali ortaya koymada yetersiz kaldığı yönündeki eleştiriler, felsefi bir çerçevede, biyo-iktidar ilişkileri de gözetilerek adalet erdemi üzerinden değerlendirilmiştir.

Published: June 2022

Air transport is considered to be the safest means of transport. However, if an accident occurs, it often ends in catastrophe. Thus, significant efforts have been paid to sustain successful operations in aviation. Several studies have been carried out to understand the underlying reasons for accidents. This study used Fault Tree Analysis (FTA), Failure Mode and Effects Analysis (FMEA) and Causal Analysis based on Systems Theory (CAST) methods to analyse Tenerife aircraft accident and to compare the findings of different methods. The findings showed that while all three methods provided some overlapping findings, the CAST method led to the identification of all causes that were identified by other methods. Considering the nature of the causal factors, FMEA provided more causal factors that are related to organisation and technology than FTA. This study indicates that CAST has a significant value to identify all causes that can be identified by the use of traditional methods.

Authors: OLUKMAN ŞAHİN Merve , ŞANLI Oya
Published: June 2022

5-Fluorouracil (5-FU), a pyrimidine analog, is a chemotherapy agent used in the treatment of a wide variety of cancers (breast, colorectal, gastrointestinal, etc.). However, its short plasma half-life, low selectivity against cancer cells and serious side effects limited its clinical use. In this study, it was aimed to minimize the negative properties of 5-FU with controlled release technology. For this purpose, 5-FU loaded poly(vinyl alcohol)/sodium alginate (PVA/NaAlg) beads were prepared by ionic crosslinking method using FeCl3 and beads were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and differential scanning calorimetry (DSC). In vitro release studies were carried out for 2 hours at 3 different pH values (1.2, 6.8 and 7.4) for a total of 6 hours. The effects of PVA/NaAlg (w/w) ratio, drug/polymer (w/w) ratio, crosslinking time and crosslinker concentration on 5-FU release were investigated. It was determined that 5-FU release increased with increasing PVA amount in the beads, whereas 5-FU release decreased with increasing crosslinking time and crosslinker concentration.

Authors: Sladkova YuN , Kriyt VE , Volchkova OV , Sklyar DN , Plekhanov VP
Published: June 2022

Introduction: The increase in time people spent in rooms of various functional purposes makes special demands on the quality of artificial lighting, which increasingly compensates for the lack of daylight. In 2021, Russian Sanitary Regulations and Standards SanPiN 1.2.3685-21 came into force setting new requirements for qualitative and quantitative characteristics of artificial lighting in residential and public buildings, thus necessitating improvement of instrumental control methods.
Objective: To develop and substantiate requirements pertaining to organization of instrumental control, procedure and conditions for measuring lighting indicators in the premises of residential and public buildings in order to control their compliance
with the updated hygienic standards.
Materials and methods: We reviewed 17 regulatory documents and guidelines containing the requirements for illumination and measurement of its parameters and analyzed more than 30 proposals for lighting assessment received from 28 territorial bodies and institutions of the Russian Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing (Rospotrebnadzor). We also considered ten main issues concerning instrumental control of lighting suggested for discussion at the meetings on activities and assignments of physical laboratories of Rospotrebnadzor Centers for Hygiene and Epidemiology in 2018–2020 and issues of illumination measurement and assessment in different types of buildings posing challenge for specialists of the Inspection Body in the course of sanitary and epidemiological expert examination of
measurement results.
Results: We have determined method approaches to organizing and taking measurements of lighting indicators and specified the choice of monitored parameters, measuring points and conditions.
Conclusion: When developing guidelines for measuring and assessing lighting inside and outside residential and public buildings, it is necessary to systematize the requirements of valid method documents, eliminate existing contradictions, and determine the choice of indicators, measuring points and conditions to be monitored.

Consolidation of efforts at the regional, national and international levels to exchange experience in the implementation of successful practices and the formation of institutional support of the sustainable energy development contributes to the post-COVID-19 revitalisation. With this in mind, the article is devoted to studying the peculiarities and experience of the post-COVID-19 revitalisation of the energy sector in different countries and determining the development prospects of climate-neutral technologies in the energy security sphere. A change in the behaviour of energy consumers by the secondary energy source in the context of increased quarantine restrictions has been established. In particular, a downward trend in the volume of energy consumption from traditional sources (oil, coal, etc.) has been traced. At the same time, the demand for energy consumption from renewable sources (solar energy, wind energy, etc.) has grown, which made it possible to diagnose the reduction in CO2 emissions. Based on the analysis of measures to reduce the negative impact of the COVID-19 on energy security in different countries, the integration of the foundations of climate neutrality through the development of new critical technologies in the field of renewable energy sources has been established. As a result of a survey of green energy stakeholders using PEST analysis, it was proved that the complexity of integrating the principles of climate neutrality into the energy sector is that the result is not an economic effect but primarily an environmental effect (energy decarbonization). As a result, a methodology for determining the sustainability indicators for developing climate-neutral technologies in energy security using fuzzy set methods is proposed. The prospect of developing climate-neutral technologies in energy security lies in the transition to cross-sectoral interaction based on a closed cycle of energy consumption from renewable sources and the use of Industry 4.0 technologies. The proposed methodology will be a tool for further research on the developing organizational and innovative support and justifying the economic feasibility of introducing climate-neutral technologies based on the clustering of industries and a circular economy in the energy security sphere.
A Brief Analysis of SDG 3 – Good Health and Well-being – and its Synergies and Trade-offs with the other Sustainable Development Goals
Authors: Venkatesh G
Published: June 2022

Sustainable Development Goals (SDGs), proposed by the United Nations in 2015, give countries around the world much to work on until 2030. The third SDG – Good health and well-being – surely cannot be pursued in isolation. Far from being a solo, it has strong synergies with other SDGs, notably Gender Equality (SDG 5), No Poverty (SDG 1), Reduced Inequalities (SDG 10) & Clean water and sanitation (SDG 6). Quite counter-intuitively, it has trade-offs with SDG 12 (Responsible Consumption and Production). This is a commentary on these synergies and trade-offs, which looks at Good Health and Well-being as an overarching goal on any government’s agenda, impacting and being impacted, to different degrees, by the other goals.

Kondisi terumbu karang diperairan Sulawesi Utara, khusus di perairan Desa Kalasey Dua sudah dirusakan oleh kegiatan reklamasi yang dimulai sejak Tahun 2011. Dampak ekologi yang sudah dirasakan oleh masyarakat nelayan akibat proyek reklamasi pantai di Kalasey antara lain: rusaknya lahan mangrove dan terumbu karang akibat penimbunan material tanah dan batu secara langsung ke dalam perairan. Akibat rusaknya ekosistim pesisir di wilayah pesisir seperti terumbu karang, algae dll, membuat berkurangnya telur dan individu dewasa cumi-cumi di wilayah pesisir. Salah satu  proses yang dilakukan untuk dapat mempertahankan kelangsungan generasi atau memcegah kepunahan suatu sumberdaya adalah reproduksi atau perkembangbiakan. Dalam konteks penyediaan sumber hidup alternatif, maka Teknologi squid attractor (atraktor cumi). merupakan salah satu sarana buatan yang dapat digunakan untuk meningkatkan daya dukung dan kelestarian sumberdaya cumi-cumi. Squid attractor mempunyai fungsi utama sebagai tempat melekatkan telur cumi-cumi sampai menetas; dan dalam kondisi tertentu sarana ini dapat berfungsi sebagai  fishing ground. Melihat Manfaat dari teknologi atraktor cumi ini, maka beberapa atraktor cumi-cumi rangka besi telah diletakan di perairan Desa Kalasey Dua, dengan tujuan utama memperkaya sumberdaya cumi-cumi di kawasan pesisir, dengan desain  atraktor yang dimodifikasi sehingga dalam pembuatanya mudah dan ramah lingkungan. Penerapan teknologi Attractor cumi ini memilik tingkat efektifitasnya antara 50 – 100 %, atau sebahagian besar sampai seluruh tali ditempeli dengan telur. Hal ini berarti ada penambahan stock sumberdaya cumi di perairan Desa Kalesey dua serta Konservasi lingkungan perairan Desa Kalasey dua.

Ikan julung-julung (Hemirhamphus far) atau ikan roa yang oleh masyarakat diolah secara tradisional dengan cara pengasapan. Gerombolan ikan ini mengadakan migrasi ke perairan Likupang untuk melakukan pemijahan, karena ikan ini yang tertangkap hampir seluruhnya dalam kondisi hampir bertelur. Dalam kondisi matang gonad ini tubuh ikan menjadi berat dan gerakan renang ikan menjadi lambat, pada saat inilah ikan ditangkap dengan pukat roa. Ecosystem Approch to Fisheries Management (EAFM) dapat dipahami sebagai sebuah konsep bagaimana menyeimbangkan antara tujuan sosial ekonomi dalam pengelolaan perikanan (kesejahteraan nelayan, keadilan pemanfaatan sumber daya ikan, dll) dengan tetap mempertimbangkan pengetahuan, informasi dan ketidakpastian tentang komponen biotik, abiotic dan interaksi manusia dalam ekosistem perairan melalui sebuah pengelolaan perikanan yang terpadu, komprehensif dan berkelanjutan. Tujuan Penelitian ini adalah menganalisis dan menentukan status perikanan julung-julung di perairan Likupang Barat dengan menggunakan domain sumber daya ikan, habitat dan ekosistem, dan teknologi penangkapan ikan. Pengelolaan perikanan julung-julung di perairan Likupang Barat, dikategorikan dalam kondisi baik, dengan penilaian domain sumber daya Ikan memiliki nilai 76,67% deskripsi “baik”, domain habitat dan ekosistem yaitu 68,33% deskripsi “baik” dan domain teknologi penangkapan ikan, nilai yang diperoleh 61,67% deskripsi “baik”. Domain yang memiliki nilai komposit kurang dari pada domain yang lain, pengelolaanya harus lebih diperhatikan dan harus ada tindakan dari pemerintah untuk mengatasinya sebelum status pengelolaannya semakin menurun.
