Asymmetric Deep Supervised Hashing
Authors: Jiang Qing-Yuan , Li Wu-Jun
Published: June 2022

Hashing has been widely used for large-scale approximate nearest neighbor search because of its storage and search efficiency. Recent work has found that deep supervised hashing can significantly outperform non-deep supervised hashing in many applications. However, most existing deep supervised hashing methods adopt a symmetric strategy to learn one deep hash function for both query points and database (retrieval) points. The training of these symmetric deep supervised hashing methods is typically time-consuming, which makes them hard to effectively utilize the supervised information for cases with large-scale database. In this paper, we propose a novel deep supervised hashing method, called asymmetric deep supervised hashing (ADSH), for large-scale nearest neighbor search. ADSH treats the query points and database points in an asymmetric way. More specifically, ADSH learns a deep hash function only for query points, while the hash codes for database points are directly learned. The training of ADSH is much more efficient than that of traditional symmetric deep supervised hashing methods. Experiments show that ADSH can achieve state-of-the-art performance in real applications.
Boosted Generative Models
Authors: Grover Aditya , Ermon Stefano
Published: June 2022

We propose a novel approach for using unsupervised boosting to create an ensemble of generative models, where models are trained in sequence to correct earlier mistakes. Our meta-algorithmic framework can leverage any existing base learner that permits likelihood evaluation, including recent deep expressive models. Further, our approach allows the ensemble to include discriminative models trained to distinguish real data from model-generated data. We show theoretical conditions under which incorporating a new model in the ensemble will improve the fit and empirically demonstrate the effectiveness of our black-box boosting algorithms on density estimation, classification, and sample generation on benchmark datasets for a wide range of generative models.
Detecting Adversarial Examples Through Image Transformation
Authors: Tian Shixin , Yang Guolei , Cai Ying
Published: June 2022

Deep Neural Networks (DNNs) have demonstrated remarkable performance in a diverse range of applications. Along with the prevalence of deep learning, it has been revealed that DNNs are vulnerable to attacks. By deliberately crafting adversarial examples, an adversary can manipulate a DNN to generate incorrect outputs, which may lead catastrophic consequences in applications such as disease diagnosis and self-driving cars. In this paper, we propose an effective method to detect adversarial examples in image classification. Our key insight is that adversarial examples are usually sensitive to certain image transformation operations such as rotation and shifting. In contrast, a normal image is generally immune to such operations. We implement this idea of image transformation and evaluate its performance in oblivious attacks. Our experiments with two datasets show that our technique can detect nearly 99% of adversarial examples generated by the state-of-the-art algorithm. In addition to oblivious attacks, we consider the case of white-box attacks. We propose to introduce randomness in the process of image transformation, which can achieve a detection ratio of around 70%.

We have studied the distribution of concentrations of bulk cadmium, as well as dissolved and suspended forms of its migration, along the continuum ‘the Mius estuary – the Taganrog Bay of the Azov Sea’. Within this area, there are located two barrier zones – the zone of the Mius River waters mixing with the Miussky Liman waters and the zone of the estuary waters mixing with the waters of the Taganrog Bay. In these barrier zones, the concentrations of all forms of cadmium increased significantly, which was due to the high wind activity observed during the study period, as a result of which, the silt deposit was stirred up, and a significant part of the cadmium previously deposited on the geochemical barriers migrated into the water. In general, in the water of the studied continuum, we observed a positive correlation of concentrations of all forms of cadmium not only with each other but also with the values of pH and salinity. For the entire studied system, the dissolved form of cadmium migration slightly prevailed over the suspended form and ranged from 50 to 75% (on average, 57%) of its gross content. At the same time, the absolute content of the dissolved form of cadmium migration did not go beyond the maximum values of the range of its concentrations in fresh surface and sea waters of the globe, as well as the MPC values for the corresponding environments.

Published: June 2022

The position of the Nizhny Novgorod Trans-Volga region in vegetation zoning schemes has long been a subject of discussion, which is due to the peculiarities of its landscape structure and long-term anthropogenic impact. This study examines the role of areas of increased phytodiversity in the post-fire part of the Kerzhensky Nature Reserve as an important component of the communities’ recovery after fires, an also deals with their spatial structure and floristic composition. A combination of field observations (geobotanical descriptions, soil profiles) and cartographic materials were used as the main research methods. We have found that the studied complex of communities was formed along an ancient long hollow, within which, due to the peculiarities of the landscape structure, was formed environment with an increased content of trace elements in soils and a greater accumulation of snow, which determined the development of rich linden-pine forests. They reflect the zonal features of the vegetation in the sandy Trans-Volga region; their preservation and further study are necessary to understand the formation processes of the vegetation cover and landscapes of this territory.

Published: June 2022

In the forest zone of the European part of Russia, among the processes actively developing within most urban agglomerations, of particular importance is the process of afforestation, i.e. an increase in the area of territories with forest vegetation due to the reduction of other types of land. The Perm urban agglomeration is no exception. The replacement of part of agricultural land with forest geosystems has become a widespread process here in recent decades, as in the entire Perm region. The paper attempts to establish the scale, pace and main causes of afforestation within the agglomeration, which is done based on the example of the Babkinsko-Yugovskoy landscape, occupying the biggest part of the agglomeration. Earth remote sensing data (Landsat open satellite data) provide a large spatial and multi-temporal coverage for analyzing the landscape and obtaining qualitative data on changes in vegetation cover over several decades. Increase in the areas of restorative successions, which started in the 1990s, reached the highest values in the period from 2010 to 2020 (6,48%). This process mainly affected agricultural lands. The main natural factors of land differentiation in terms of the scale and rate of withdrawal from agricultural use are the small contours of a large part of agricultural land and difference in soil fertility.

Published: June 2022

The article deals with digitization of agriculture as the determinative direction of crop production intensification in Kazakhstan. The main condition for the digitization to be implemented is the development of precision agriculture. The aim of our work is to study the process of agricultural digitization in Kazakhstan and particularly the North Kazakhstan region, which is the oldest territory of rainfed agriculture and the leading area in terms of crop production by value and in terms of economic fertility of rainfed land. We analyze the main provisions of state programs (‘Kazakhstan–2050’, ‘Digital Kazakhstan’) aimed at integrating geospatial technologies into farming and crop production, which is supposed to increase labor productivity in the industry. In the course of research, the peculiarities of using satellite imagery and shooting from unmanned aerial vehicles in precision agriculture were noted; factors that hinder the introduction of digital technologies in the development of agriculture were identified; SWOT analysis of environmental and economic conditions of the precision agriculture development in the region was carried out. The article proposes measures to be taken for further development of agricultural digitization in the region: both innovative (development of agrarian voltaics) and paternalistic ones (state stimulation of agrarian formations, etc.). The digitization of the agricultural sector will create econologically sustainable programmable system of farming based on high natural agricultural potential and advanced geospatial technologies resting on predictive analytics.

Published: June 2022

Climate warming is causing an increase in the total moisture content on the planet and in the number of heavy rainfall cases. Many of these result in severe flooding, victims, and destruction of infrastructure. The aim of the study is to establish the possibility of improving the quality of heavy precipitation forecasting by reducing the step of the computational grid in the mathematical model of the atmosphere. The article presents the results of a study of extreme summer precipitation in the Ural Kama region for the period from 1979 to 2015. The statistical characteristics of 37 precipitation cases with an intensity of more than 50 mm in 12 hours were analyzed. Computational experiments were performed on the WRF-ARW regional atmospheric model. The meteorological conditions for the occurrence of heavy rain in town of Gubakha with an extreme intensity of 114,5 mm in 12 hours were taken as a special case for the study. A qualitative assessment of the simulation results showed that for the selected case, the model correctly reproduced the general structure of heavy rains, but significantly shifted it eastward. A quantitative assessment of the forecast quality was conducted for numerical forecast of heavy precipitation based on the WRF-ARW model at a grid step of 3 km and 7,2 km. The quality of the model was evaluated based on the forecast accuracy not only at the measurement point but also in the vicinity within a radius of 50 km. It was found that there was no significant improvement in the quality of the forecast of high-intensity precipitation when switching to a smaller grid step according to both the first and second assessment methods. The results obtained can be taken into account when preparing forecasts of heavy rains occurrence and when developing flood forecast techniques.

Published: June 2022

An urban heat island is a phenomenon which occurs when the temperature in urban areas is higher than that in their rural surroundings. The formation of an urban heat island has a negative impact on the health of urban dwellers and the ecology of the city. We assessed the intensity of the surface urban heat island (UHISurf) in the city of Novosibirsk during the summer period from 2018 to 2020 using two categories of indicators – those based solely on differences in temperature (UHI-driven) and those including land cover type data (land-cover-driven). Data from the Landsat 8 were used to obtain information on land surface temperature. In accordance with the chosen methodology, bands 4, 5 and 10 were taken to calculate the land surface temperature. A prerequisite for satellite data selection was the absence of cloud cover over the study area. In this paper, nine buffers with a diameter of 1 km were selected, each around ground-based meteorological observation points at the Roshydromet network of stations. The results obtained indicate the presence of a stable surface urban heat island in Novosibirsk during the study period. The maximum value among all surface urban heat island intensity indicators was 23,0°C for the range indicator. Negative intensity values (up to –1,6°C) were also obtained for several cases, which is associated with a larger heating of croplands relative to urban surfaces. It is concluded that UHISurf intensity values depend on the choice of the calculation approach.

Published: June 2022

Unfavorable hydrothermal conditions and excessive pasture loads in the European South of Russia led to dust storms in September and October 2020 and in May and June 2021. As a result, the area of desertification in the Republic of Dagestan, the Republic of Kalmykia, Astrakhan Oblast and Stavropol Krai has increased several times. The UNESCO biosphere reserve ‘Kizlyar Bay’ is located in the north of Dagestan. Economic activities, including grazing, are allowed in its cooperation zone. Overgrazing led to a 15% (about 90 km2) increase in the area of land without vegetation in 2021 as compared to 2019. It is necessary to take urgent measures aimed at regulating livestock population, controlling compliance with the grazing regime of distant-pasture cattle breeding, carrying outvegetative reclamation, and organizing a monitoring system to prevent further pasture degradation in the cooperation zone of the reserve.

Published: June 2022

Background: Rivers and their associated vegetation are considered highly complex natural systems representing high biodiversity areas that work as biological corridors. Nevertheless, riparian vegetation of the Monarch Butterfly Biosphere Reserve (MBBR) has not been studied nor considered in the reserve’s management program. Questions: Which is the composition, structure, diversity, and state of conservation of the riparian vegetation of the MBBR? Study site and dates: The Senguio Microbasin, part of Sierra Chincua Priority Terrestrial Region, within the MBBR, in central México. 2016-2017. Methods: Using high-resolution imagery from 2014, we identified five joint categories in relation to the protection status (Core Zone, Buffer Zone, and Influence Area) and land use (conserved forest, highly disturbed forest, and farmland). We sampled three sites per category (N = 15) to analyze the composition, richness, and α- and β-diversity of the riparian communities. Results: We registered 108 species, 46 genera, and 18 families, of which 98 % are native and 2 % exotic. Richness and α-diversity were not significantly different among sites, but the composition and β-diversity showed significant differences depending on land use. The riparian vegetation is well conserved both in the Reserve´s Core and Buffer zones, and preserves high coverage, species richness, and individuals’ abundance. Conclusions: The riparian vegetation of the Senguio Microbasin hosts a biodiversity richness critical for the ecosystem’s health and evidences the relevance of considering the human use of the riparian systems to succeed in the conservation strategies.
A phytogeographic assessment of the Sierra Madre Oriental physiographic province, Mexico
Authors: Villaseñor José Luis , Ortiz Enrique
Published: June 2022

Background: Different regionalizations have been proposed for the Sierra Madre Oriental (SMOR), but none of them have analyzed its full floristic diversity.
Hypothesis: The geographical distribution of the vascular plant species of the SMOR allows the identification of floristic regions with unique species that identify them as biogeographic units.
Studied species: Vascular plants.
Study site: Sierra Madre Oriental physiographic province, Mexico.
Methods: Plant species distribution was analyzed in 1 × 1° latitude and longitude grid cells. Characteristic species (those with half or more of their known geographical distribution in Mexico in the SMOR) were identified, and a classification method was applied to distinguish biogeographic regions.
Results: 8,472 species were recorded in the Sierra Madre Oriental, 3,433 of them considered characteristics, of which 2,158 are endemic to Mexico and 585 are considered strictly endemic to the province. The portions of the SMOR in the states of Coahuila, Nuevo León, Tamaulipas, and San Luis Potosí have a higher species richness and this richness decreases towards the south of the province. Five floristic districts were identified within the SMOR.
Conclusions: The phytogeographic analysis carried out and its comparison with other regionalizations shows there is still disagreement in the biogeographic delimitation of the Sierra Madre Oriental and to achieve this goal it is necessary to include neighboring provinces in the analyzes, which will allow to identify their unique species and define their biogeographic limits in a more precise way.

Published: June 2022

The study investigates that behavioral intention can be affected by different factors, by associating slow tourism with the concept of authenticity and attachment to place. Cittaslow (slow city) is a social movement and organization that promotes slowness in lifestyle. Halfeti district, which is within the scope of slow city in Turkey, was chosen as the research area and the data were collected from the tourists in this region. Using the convenience sampling method, the study was analyzed with the data of 415 questionnaires. Smart PLS 3 (PLS-SEM) analysis technique was used to test the proposed model. According to the results of the structural equation model, it was determined that the dimensions of authenticity and authenticity (objective, structural and existential) positively affect the attachment to the place and its dimensions (place dependence, place identity, place effect, place social bond). However, no positive effect was found between place effect and place social bond, which are the dimensions of attachment to the place of the structural dimension of authenticity. On the other hand, it has been determined that attachment to place and its dimensions (place dependence, place identity, place effect, place social bond) have a positive effect on behavioral intention.

Capital Market Boad of Turkey (CMB) has to authority to give audit firms to be engaged in independent audit activity in capital market in Turkey, based on the regulation “Principles Regarding Independent Auditing Standards in the Capital Markets- (Serial: X, No:22)”. Then, it is very likely that these firms engaged operate in a more demanding and competitive environment than the other audit firms’ since these firms have a crucial communication with capital markets’ investors, and stakeholders, through their fianl and vital decision, audit opinion. Altough requirements specified by the regulation, however, prior research do not demonstrate the differences between the audit firms operating in capital markets and the others registered by the Public Oversight Accounting and Auditing Standards Authority (POA). This study aims to examine the firm relevant attributes having an influence on the likelihood of undertaking audits in capital market in Turkey. Through a sample of 349 audit firms registered in POA, logistic regression model results showed that the number of years after being registered by POA, city’s population density of audit firm’s head office, and audit team size increases the audit firm’s likelihood to underrtake audits in capital market of Turkey. The results refer to the effectiveness of auditing standards in the Turkish capital markets and likely to be beneficial both to regulatory authorities and also to independent audit firms.

Bu çalışmada, demir içeren içme suyu arıtma tesis çamurunun (DWTS) arsenik ve antimon giderim performansı araştırılmıştır. DWTS üç farklı sıcaklıkta (200, 400 ve 600ºC) termal arıtmaya tabi tutularak modifiye edilmiştir (DWTS-200). 200ºC, 1saat ısıl işlem uygulanmış malzeme ile maksimum arsenik giderimi elde edilmiştir. Malzemenin yüzey alanı ve gözenek hacmi BET metoduyla analiz edilmiş, faz kompozisyonu X-ışını difraksiyonu (XRD) ile belirlenmiştir. Yüzey morfolojileri ve element analizi taramalı elektron mikroskobu (SEM) ve X-ışını spektrometresi (EDS) ile gerçekleştirilmiştir. Sonuçlar DWTS-200 malzemesinin oldukça yüksek yüzey alanına sahip olduğunu (170 m2 g-1) ve amorf yapısının baskın olduğunu göstermiştir. Malzemenin ana fazları ağırlıklı olarak demir, kalsit, oksijen ve quartzdan oluşmuştur. 40 µg As L-1 ve 80 µg Sb L-1 konsantrasyonları için kırılma noktasına ulaşıncaya kadar arsenik için 6.000 L (133.000 yatak hacmi sayısı), antimon için 640 L (14.000 yatak hacmi sayısı) su arıtabildiği belirlenmiştir. Kolon tasarımı için gerekli kinetik parametreleri belirlemek ve kırılma eğrilerini tahmin etmek için Thomas ve Yoon-Nelson modelleri uygulanmıştır. Her iki model adsorpsiyon sürecinin dinamik davranışını açıklamak için uygun bulunmuştur. Thomas modeliyle arsenik için maksimum adsorpsiyon kapasitesi 6,53 mg g-1, antimon için 5,21 mg g-1 olarak elde edilmiştir. Ayrıca, DWTS-200 adsorban malzemeye rejenerasyon uygulanmış ve malzemenin rejenere edilerek kullanılabileceği görülmüştür.

Geleneksel gama tipi Stirling motorlarında iki silindir mevcut olup silindirlerden birisi aracılığı ile çalışma gazının sıkıştırılması ve genişletilmesi işlemleri, diğeri aracılığı ile çalışma gazının sabit hacimde ısıtılması ve soğutulması işlemleri gerçekleştirilmektedir. Geleneksel gama tipi motorlarda soğuk ve sıcak hacimlerin aynı silindirde bulunması nedeni ile sıcak uçtan soğuk uca iletimle önemli bir miktarda ısı kaybı olmaktadır. Ayrıca dispileyser’ in yapımı oldukça külfetli bir iştir. Bu problemleri yok etmek için, son zamanlarda sıcak ve soğuk hacimleri ayrı ayrı silindirlerde bulunan üç silindirli gama tipi bir motor modeli tanıtılmıştır. Bu motorlarda bulunan silindirlerden birisi sıcak hacim olarak bir diğeri soğuk hacim olarak üçüncüsü de güç silindiri olarak görev yapmaktadır. Bu motorların termodinamik süreçleri geleneksel gama tipi motorunkine çok benzediği için bunlara üç silindirli gama tipi motor adı verilmiştir. Her üç silindirin içerisinde alışılmış tipten pistonlar çalışmaktadır. Bu araştırmada geleneksel gama tipi bir motorun ve üç silindirli gama tipi bir motorun nodal termodinamik analizleri yapılarak performansları kıyaslanmıştır. Motorların çevrimlik işlerinin ve verimlerinin birbirine çok yakın olduğu görülmektedir. Yüksek hızlarda ve yüksek basınçlarında geleneksel gama tipi motorun, yüksek sıkıştırma oranında ise üç silindirli gama tipi motorun az miktarda avantajlı olduğu görülmektedir.

Published: June 2022

İşyerinde var olan ya da dışarıdan gelebilecek tehlikelerin belirlenmesi, bu tehlikelerin riske dönüşmesine yol açan faktörler ile tehlikelerden kaynaklanan risklerin analiz edilerek derecelendirilmesi ve kontrol tedbirlerinin kararlaştırılması amacıyla literatüre önerilmiş birçok çalışma bulunmaktadır. Risk değerlendirme çalışmaları uzmanların öznel yargılarına ve uzmanlık derecelerine bağlı olarak gerçekleşir. Bu nedenle literatürde uzman değerlendirmelerindeki belirsizlikleri ele almak için bulanık mantık temelli çeşitli risk analiz tekniklerinin uygulandığı çalışmalar görülmektedir. Risk değerlendirmesinde genel olarak en olası duruma göre karar verilmektedir. Oysa olası durumlardan ziyade nadiren gerçekleşen sonuçlar da risk değerlendirmesinde kararsızlık yaratmaktadır. Bununla birlikte herhangi bir riske karşı uygulanan önlemler değerlendirilirken ilgili riski ne dereceye kadar önleyebileceğine dair bir değerlendirmenin de yapılmaması diğer bir kararsızlık unsurudur. Bu nedenle bu çalışma kapsamında, risk değerlendirme sürecindeki tutarsızlıkları, öznellikleri ve kararsızlıkları ele almak için nötrosofik küme tabanlı Hata Türleri ve Etkileri Analizi (Failure Mode and Effect Analysis-FMEA) literatüre ilk kez önerilmektedir. Önerilen modelde, FMEA yönteminde kullanılan olasılık, şiddet ve tespit edilebilirlik parametrelerinin tanımlanmasında nötrosofik küme tanımında kullanılan doğruluk (T), karasızlık (I) ve yanlışlık (F) parametrelerine ait üyelik dereceleri kullanılarak bir riske ilişkin uzman değerlendirmesinin farklı boyutları ve riske değerlendirmesine yönelik kararsızlıklar dikkate alınmaktadır. Önerilen yaklaşımda potansiyel hata türleri, hatanın etkisi ve hata türlerinin tespiti için kontrol noktaları belirlenerek bu noktaların koşulları doğruluk derecesi, yanlışlık derecesi ve kararsızlık derecesi dikkate alınarak analiz edilmiştir. FMEA parametrelerine bağlı olarak riskin belirlenmesinde çarpma işlemi yerine Mamdani bulanık çıkarım sistemi kullanılmaktadır. Çalışmada geliştirilen risk değerlendirme yönteminin uygulama adımlarını örneklendirmek amacıyla kimya sektörüne bir uygulama sunulmuştur. Uygulamadan elde edilen sonuçlar klasik FMEA ve Bulanık FMEA sonuçlarıyla kıyaslanarak önerilen yöntemin mevcut yöntemlere göre risk değerlendirmedeki kararsızlıkları ve öznelliğe bağlı belirsizlikleri dikkate almadaki başarısı gösterilmiştir.

Published: June 2022

Hiperspektral görüntüler (HG), iki uzamsal ve bir spektral boyuta sahip 3 boyutlu (3B) görüntü küpleridir. Derin öğrenme yöntemlerinin gelişimi, HG sınıflandırmada önemli bir etki oluşturmuştur. Özellikle evrişimsel sinir ağı (ESA) tabanlı yöntemler bu alanda daha fazla ilgi görmektedir. Bu çalışmada, HG sınıflandırma problemi için ESA’nın başarılı örnekleri arasında olan LeNet5, AlexNet, VGG16, GoogleNet ve ResNet50 derin öğrenme mimarilerinden yararlanıyoruz. Bu mimarileri kullanırken 3B ESA tabanlı hibrit bir yaklaşım kullanmaktayız. Çünkü, 3B ESA kullanılarak, spektral-uzamsal özellikler eş zamanlı olarak çıkarılmaktadır. Bu durumda elde edilen spektral-uzamsal tabanlı derin öğrenme mimarisi ile HG’lerin sınıflandırma doğruluğu arttırılmaktadır. Bununla birlikte, önerilen modelde, HG'lerden optimal bant çıkarımı için bir ön işleme tekniği olarak temel bileşen analizi (TBA) kullanılmaktadır. TBA uygulandıktan sonra komşuluk çıkarımı ile 3B küpler elde edilmekte ve derin öğrenme mimarilerinin girişine verilmektedir. 3B ESA tabanlı derin öğrenme mimarilerinin sınıflandırma performanslarını karşılaştırmak için Indian pines, Salinas, Botswana ve HyRANK-Loukia verisetleri kullanılmıştır. Gerçekleştirilen uygulamalar sonucunda, en iyi sınıflandırma doğruluğu Indian pines verisetinde VGG16, Botswana verisetinde ResNet50, HyRANK-Loukia verisetinde VGG16, Salinas verisetinde LeNet5 ve VGG16 mimarileri ile elde edilmiştir.

This protocol outlines the NanoString GeoMx DSP protein assay that was applied in the Human Tumor Atlas Network (HTAN) Tissue MicroArrary (TMA) -TransNetwork Project (TNP). The TMA-TNP evaluates various characterization and analytics methodologies on a large array of breast tumor samples representing a broad spectrum of disease state and subtype. A commercially available anonymized breast tumor TMA was purchased and serial sections were distributed. Participating HTAN Centers characterized the FFPE specimens using various imaging platforms and generated a spatially resolved cell type/state census using each center’s method of choice. Data was recorded in a common repository to enable joint analysis. The protocol that immediately precedes this one for TMA-TNP Phase 3 (when this NanoString GeoMx DSP protein assay protocol was first tested) can be found at: dx.doi.org/10.17504/protocols.io.6qpvr6992vmk/v1. It describes FFPE block serial sectioning, slide processing and TMA sample distribution. In this protocol, the DSP protein assay was performed with the following human marker panels: Immune cell profiling core, Immune activation status, Immune-Oncology (IO) Drug target, Cell death, Pan-tumor, MAPK and PI3K/AKT panels including OHSU custom panel (Cell cycle and DNA damage). A total of 87 protein targets were evaluated in the TMA samples. Three compartments (Immune, Tumor and Stroma) in each TMA core were analyzed to determine cell-to-cell interactions in the tissues.

Published: June 2022

The study presents an algorithm and results of the multiparametric optimization for high-flow centrifugal compressor stages. We present the use of a CAD parameterized model of the compressor stage in the automated computational optimization procedure by the AMO – Adaptive Multiple-Objective method in the Ansys complex. To predict the compressor stage efficiency in the design mode, a viscous three-dimensional CFD calculation is used. As an objective function of the optimization problem, the stage total to total polytropic efficiency and the total to total polytropic head coefficient constraint are selected. The algorithm was used for the centrifugal compressor stages improvement. As a result, the efficiency was increased by 1.5-2.5%, and the stages energy–efficient operation zone was expanded by 30% - 60%. The results of the study showed that computational optimization can be successfully applied for the projected centrifugal compressor flow part fine-tuning to obtain the highest efficiency.

For pectin-containing film structures, which are used for the production of biodegradable packaging materials and are hydrophilic in nature, their paraffinization, i.e., applying a thin layer of molten food paraffin to the surface of the film for subsequent protection of packaged food products from moisture and sunlight, will reduce the influence of external factors, primarily moisture, To rationalize the convective preconcentration of a hexane solution, it is necessary to select such regime parameters that will allow not only the removal of hexane with toxic components dissolved in it from the object of study in a relatively simple apparatus, but also significantly reduce the time for the process within temperature restrictions. The latter condition, in view of the complexity of the empirical determination of the temperature distribution in a thin layer of the object of concentration, is advisable to implement by solving the system of equations for the transfer of thermal energy and mass in partial derivatives, however, we can restrict ourselves to one equation for the transfer of thermal energy, using empirical kinetic dependences that describe the removal of n-hexane from the composition. The aim of the study was to adapt paraffin to a hexane solution and solve the model of heat and mass transfer during its concentration in order to exclude the possibility of reducing its temperature below the value of possible preliminary crystallization. The model was implemented numerically by the finite difference method. As a result of the solution, the intensity of the temperature front advancement along the height of the film of the hexanoparaffin composition was found with varying the proportion of paraffin in the process of its concentration with convective supply of thermal energy to it, i.e., it was adapted to the resulting solution and a mathematical model of heat and mass transfer was solved during its concentration to eliminate the likelihood of a decrease in its temperature below the value of possible pre-crystallization. The data obtained do not conflict with the known results of other researchers and can be successfully used for operational calculation and design of the designated processes and units.

BACKGROUND: Emotional burnout syndrome is described in the historical literature. According to various authors, the syndrome develops on average in 50% of contemporary teachers. However, the influence of the syndrome on the health of university teachers and its risk factors have not been sufficiently investigated. AIM: This study aimed to identify and analyze the specific of risk factors influencing the health of university teachers. MATERIALS AND METHODS: An anonymous survey of 1,417 teachers was conducted at humanities institutions of higher education in Moscow, and the results of medical examinations were studied. RESULTS: The prevalence of health disorders and associated risk factors among teachers were studied. The socio-hygienic characteristics of the surveyed teachers were analyzed based on a comprehensive assessment of their emotional state, according to individual diseases. In addition, the methods of improving their health status were determined. CONCLUSIONS: More than half of university teachers have health disorders associated with adverse occupational factors and the moral and psychological climate at work and at home, combined with poor health and socio-hygienic activity indicators. Their management should include health-improving technologies and ensure optimal conditions for professional activity.

Published: June 2022

Community psychiatry has its origins in the West, in the 1950s, when many institutions for the mentally ill were closed down in an effort to shift the focus from hospital-based care to community-based. The aim of the current paper is to review the available literature on the community-based psychiatric treatment in Romania.
The Romanian Ministry of Health is dedicated to promoting mental health education and to creating a mental health system that ensures that every patient has access to care and treatments designed for their own particular needs. Today, in Romania, as across the entirety of Central and Eastern Europe, mental health systems are transitioning from hospital-based care to community-based services. The RECOVER-E project, the SEE Mental Health Project, the Horizons project, among others, showcase Romanias mental healthcare system in terms of improving the chances of mental health patients recovery.
Community Psychiatry in Romania is a budding field that can greatly aid in the management and treatment of patients with mental disorders from both urban and rural areas. By applying the principles of deinstitutionalization and community health care at a systemic level, resources may be invested in the creation of a strong network of specialists that treat patients in their own living spaces.

Published: June 2022

Purpose: This study aims to evaluate olfactory and gustatory dysfunctions (OGDs) in COVID-19 patients according to hospital admission type and possible risk factors for OGD.
Materials and Methods: This study included 200 adult patients who were diagnosed with COVID-19 between January 2021 and September 2021. Patients were separated into two groups. The first group comprised 100 patients who applied to pandemic outpatient clinics with a milder course and were isolated at home. The second group comprised 100 patients with a more severe clinical course hospitalized in the pandemic ward. Patients completed a data form in which olfactory and gustatory functions and various clinical information were inquired about and rated their smell and taste dysfunction using a visual analog scale (VAS).
Results: In the ambulatory group, 72% of patients were female and the mean age was 39.6±13.2 years. In the admitted group, 50% of patients were female, and the mean age was 52.4±11.0 years. The most common symptoms in all patients were loss of taste (41%) and smell (45.5%). Females and younger individuals were significantly more likely to have OGD. OGD was more common in the ambulatory group. Smell/taste VAS scores were significantly lower in the ambulatory group.
Conclusion: OGD is associated with various mechanisms depending on the increased inflammatory response in the early stages of COVID-19. OGD appears to be the key symptom and diagnostic indicator and should be inquired about. It should be kept in mind that the frequency of OGD may differ according to age and gender.

Hymenoptera venom immunotherapy (VIT) is effective for protecting individuals with systemic allergic reactions caused by Hymenoptera stings. The need for a tool that shows the degree of protection afforded by VIT and the lack of useful biomarkers have made the sting challenge test (SCT) the gold standard for this disorder, although its use has both lights and shadows. SCT with Hymenoptera involves causing a real sting in a patient diagnosed with allergy to the venom of the stinging insect and who is undergoing treatment with specific immunotherapy. In Spain, SCT is included in the list of services offered by some hospitals and forms part of their daily clinical practice. This review aims to analyze the strengths and weaknesses of this test and to describe the standardized procedure and necessary resources, based on the experience of a group of Spanish experts and a review of the literature.
If there was a hut, there would be cockroaches (cockroach as a character of Russian folklore)
Authors: Spiridonova Elena V. , Obnorskaia Nina V.
Published: June 2022

Cockroaches have accompanied people for a significant part of their history. On the one hand, it’s a pest that should be eliminated by all means, and magical methods peacefully coexisted with rational ones. On the other hand, according to the peasants with their mythological thinking, there was also a benefit from cockroaches. Remarkably that black cockroaches were considered more useful, they were perceived as a symbol of prosperity and patrons of livestock. Red or German cockroaches were perceived as more harmful and methods of getting rid of pests were applied to them in the first place. All this proves the binary perception of cockroaches which were close to the mythological world and its inhabitants and, accordingly, acted as bearers of both harm and good.
