Combining dental ceramics with other prosthetic metallic restorations might release metal ions, thus affecting the oral tissues of the patients. In this study, we evaluated the electrochemical solubility of various dental ceramics in a galvanic experimental setup in vitro. Smooth and rough feldspathic and zirconium dioxide ceramics (at pH 5.5 and pH 3.0) were exposed to an electric field. Calcium, barium, and zirconium were selected as parameters to determine the solubility of both types of ceramic materials. Among all test groups, feldspathic ceramics were more soluble than zirconium dioxide ceramics at low pH. The results indicated that the solubility of zirconium dioxide was not significantly affected by the presence of an electric field, although the solubility was higher when the pH was relatively lower. The feldspathic material had a higher sensitivity to acids and electrogalvanic processes. We found that the galvanic process increases the solubility of feldspathic ceramics. The surface quality is important in an acidic medium, especially for feldspathic ceramics. Zirconium dioxide ceramics are more resistant to an acidic medium and exposure to a clinically relevant electric field.
Attention-Based Models for Classifying Small Data Sets Using Community-Engaged Research Protocols: Classification System Development and Validation Pilot Study
Authors: Ferrell Brian J , Raskin Sarah E , Zimmerman Emily B , Timberline David H , McInnes Bridget T , Krist Alex H
Published: June 2022

Background

Community-engaged research (CEnR) is a research approach in which scholars partner with community organizations or individuals with whom they share an interest in the study topic, typically with the goal of supporting that community’s well-being. CEnR is well-established in numerous disciplines including the clinical and social sciences. However, universities experience challenges reporting comprehensive CEnR metrics, limiting the development of appropriate CEnR infrastructure and the advancement of relationships with communities, funders, and stakeholders.

Objective

We propose a novel approach to identifying and categorizing community-engaged studies by applying attention-based deep learning models to human participants protocols that have been submitted to the university’s institutional review board (IRB).

Methods

We manually classified a sample of 280 protocols submitted to the IRB using a 3- and 6-level CEnR heuristic. We then trained an attention-based bidirectional long short-term memory unit (Bi-LSTM) on the classified protocols and compared it to transformer models such as Bidirectional Encoder Representations From Transformers (BERT), Bio + Clinical BERT, and Cross-lingual Language Model–Robustly Optimized BERT Pre-training Approach (XLM-RoBERTa). We applied the best-performing models to the full sample of unlabeled IRB protocols submitted in the years 2013-2019 (n>6000).

Results

Although transfer learning is superior, receiving a 0.9952 evaluation F1 score for all transformer models implemented compared to the attention-based Bi-LSTM (between 48%-80%), there were key issues with overfitting. This finding is consistent across several methodological adjustments: an augmented data set with and without cross-validation, an unaugmented data set with and without cross-validation, a 6-class CEnR spectrum, and a 3-class one.

Conclusions

Transfer learning is a more viable method than the attention-based bidirectional-LSTM for differentiating small data sets characterized by the idiosyncrasies and variability of CEnR descriptions used by principal investigators in research protocols. Despite these issues involving overfitting, BERT and the other transformer models remarkably showed an understanding of our data unlike the attention-based Bi-LSTM model, promising a more realistic path toward solving this real-world application.

Published: June 2022

Background

Digital peer support is an increasingly used form of mental health support for young people. However, there is a need for more research on the impact of digital peer support and why it has an impact.

Objective

The aim of this research is to examine young people’s experiences of using a digital peer support tool: MeeToo. After the time of writing, MeeToo has changed their name to Tellmi. MeeToo is an anonymous, fully moderated peer support tool for young people aged 11-25 years. There were two research questions: (1) What impacts did using MeeToo have on young people? (2) Why did using MeeToo have these impacts on young people?

Methods

A mixed methods study was conducted. It involved secondary analysis of routinely collected feedback questionnaires, which were completed at two time points (T1 and T2) 2-3 months apart. Questionnaires asked about young people’s (N=876) experience of using MeeToo, mental health empowerment, and well-being. Primary data were collected from semistructured interviews with 10 young people.

Results

Overall, 398 (45.4%) of 876 young people completed the T1 questionnaire, 559 (63.8%) completed the T2 questionnaire, and 81 (9.2%) completed both. Descriptive statistics from the cross-sectional analysis of the questionnaires identified a range of positive impacts of using MeeToo, which included making it easier to talk about difficult things, being part of a supportive community, providing new ways to help oneself, feeling better, and feeling less alone. Subgroup analysis (paired-sample t test) of 58 young females who had completed both T1 and T2 questionnaires showed a small but statistically significant increase in levels of patient activation, one of the subscales of the mental health empowerment scale: time 1 mean=1.83 (95% CI 1.72-1.95), time 2 mean=2.00 (95% CI 1.89-2.11), t59=2.15, and P=.04. Anonymity and the MeeToo sense of community were identified from interviews as possible reasons for why using MeeToo had these impacts. Anonymity helped to create a safe space in which users could express their feelings, thoughts, and experiences freely without the fear of being judged by others. The MeeToo sense of community was described as a valuable form of social connectedness, which in turn had a positive impact on young people’s mental health and made them feel less isolated and alone.

Conclusions

The findings of this research showed a range of positive impacts and possible processes for young people using MeeToo. Future research is needed to examine how these impacts and processes can be sustained.
Identifying the Risk of Sepsis in Patients With Cancer Using Digital Health Care Records: Machine Learning–Based Approach
Authors: Yang Donghun , Kim Jimin , Yoo Junsang , Cha Won Chul , Paik Hyojung
Published: June 2022

Background

Sepsis is diagnosed in millions of people every year, resulting in a high mortality rate. Although patients with sepsis present multimorbid conditions, including cancer, sepsis predictions have mainly focused on patients with severe injuries.

Objective

In this paper, we present a machine learning–based approach to identify the risk of sepsis in patients with cancer using electronic health records (EHRs).

Methods

We utilized deidentified anonymized EHRs of 8580 patients with cancer from the Samsung Medical Center in Korea in a longitudinal manner between 2014 and 2019. To build a prediction model based on physical status that would differ between sepsis and nonsepsis patients, we analyzed 2462 laboratory test results and 2266 medication prescriptions using graph network and statistical analyses. The medication relationships and lab test results from each analysis were used as additional learning features to train our predictive model.

Results

Patients with sepsis showed differential medication trajectories and physical status. For example, in the network-based analysis, narcotic analgesics were prescribed more often in the sepsis group, along with other drugs. Likewise, 35 types of lab tests, including albumin, globulin, and prothrombin time, showed significantly different distributions between sepsis and nonsepsis patients (P<.001). Our model outperformed the model trained using only common EHRs, showing an improved accuracy, area under the receiver operating characteristic (AUROC), and F1 score by 11.9%, 11.3%, and 13.6%, respectively. For the random forest–based model, the accuracy, AUROC, and F1 score were 0.692, 0.753, and 0.602, respectively.

Conclusions

We showed that lab tests and medication relationships can be used as efficient features for predicting sepsis in patients with cancer. Consequently, identifying the risk of sepsis in patients with cancer using EHRs and machine learning is feasible.
News Coverage of Colorectal Cancer on Google News: Descriptive Study (Preprint)
Authors: Basch Corey H , Hillyer Grace C , Jacques Erin T
Published: June 2022

BACKGROUND

Colorectal cancer (CRC) is one of the leading causes of cancer death in the United States. The incidence and prevalence of CRC have historically increased with age. Although rates of CRC in the United States have been decreasing over the past decades among those aged ≥65 years, there has been an uptick among those in younger age brackets. Google News is one of the biggest traffic drivers to top news sites. It aggregates and shares news highlights from multiple sources worldwide and organizes them by content type. Despite the widespread use of Google News, research is lacking on the type of CRC content represented in this news source. 

OBJECTIVE

The purpose of this study was to analyze content related to CRC screening and prevention in Google News articles published during National Colorectal Cancer Awareness Month (March 2022).

METHODS

Data collection for this cross-sectional study was conducted in March 2022—National Colorectal Cancer Awareness Month. Using the term colorectal cancer, 100 English-language Google News articles were extracted and coded for content. A combined approach—deductive and inductive coding—was utilized. Descriptive analyses were conducted, and frequency distributions were reported. Univariable analyses were performed to assess differences between articles that mentioned CRC screening and those that did not via chi-square tests.

RESULTS

Of the 100 articles reviewed, nearly half (n=49, 49%) were created by health news organizations, and another 27% (n=27) were created by television news services. The predominant themes in the content included age at the onset of disease (n=59, 59%), mortality related to CRC (n=57, 57%), and the severity of disease (n=50, 50%). Only 18% (n=18) of articles discussed CRC disparities, 23% (n=23) mentioned that there are hereditary forms of the disease, 36% (n=36) spoke of colonoscopy to screen for the disease, and 37% (n=37) mentioned how the disease is treated. Although most articles mentioned CRC screening (n=61, 61%), it was striking that sex was only mentioned in 34% (21/61) of these articles, colonoscopy was mentioned in 46% (28/61), and diet was mentioned in 30% (18/61).

CONCLUSIONS

Heightening the public’s awareness of this disease is important, but it is critical that messages related to how preventable this cancer is, who is the most likely to develop CRC, and what can be done to detect it in the early stages when the disease is the most curable be the critical elements of dialogue, particularly during National Colorectal Cancer Awareness Month. There is a need to disseminate information about early-onset CRC and the importance of screening, especially among populations with low rates of uptake. Web-based news is potentially an underutilized communication mechanism for promoting CRC screenings as secondary prevention measures for high-risk groups.

Authors: Choukou Mohamed-Amine , Olatoye Funminiyi , Urbanowski Reg , Caon Maurizio , Monnin Caroline
Published: June 2022

BACKGROUND

Digital health technology (DHT) is a promising way of supporting healthcare providers (HCPs) and family caregivers (FCs) as they care for patients with cognitive impairment (CI).

OBJECTIVE

This scoping review aimed to portray the use of DHT to assist HCPs and FCs in caring for patients with CI who live in the community or a facility.

METHODS

A scoping review of peer-reviewed scientific articles available in Medline, PsycINFO, Scopus and Cinahl with Full Text, and grey literature available in preprint servers, theses depositories, and various national and international dementia organizations’ websites. The search yielded 975 results and the final number of studies included was 7.

RESULTS

The interventions included in the retrieved manuscripts were 2 interactive calendar reminder systems to support ADL and medication management; 2 apps on tablet to simulate the presence of family before therapy interventions; 1 social robot used in therapeutic sessions to include elements of musicotherapy, reminiscence, cognitive games, and relaxation; 1 commercially available computer system that provides access to various recreational leisure activities; and an online self-management support system that helps FCs deal with behaviour changes of a relative with dementia. Only one manuscript reported on the use of a behavioural change theory, namely a comprehensive process model of engagement coupled with cognitive stimulation therapy.

CONCLUSIONS

Literature on the topic is scarce, recent, and heterogeneous. There is a clear need for a theoretical framework to conceptualize and govern the use of behaviour change models that incorporate technology for patients with CI.

How to link: Plasmid Curing and Lead Tolerance Ability of Pediococcus pentosaceus
Authors: Al-Kanany Fadhil Neamah , Jaafar Raghad Shubbar
Published: June 2022

Pediococcus pentosaceus has a high level of resistance to heavy metals, making it one of the biological alternatives for dealing with heavy metal contamination in the environment. The current study sought to identify the genetic factors responsible for this ability by curing the plasmid of these bacteria using various curing agents (Acridine orange and Sodium Dodecyl Sulfate). The findings demonstrate that both curing agents had perfect curing ability. The bacteria were able to tolerate a wide range of Lead concentrations (50-2000 ppm). This capacity was reduced when the plasmid was removed, but it did not disappear, implying additional resistance genes on the chromosomes. The antibiotic susceptibility observations supported the significance of plasmid genes in lead resistance ability, the findings revealed differences in the pattern of antibiotic resistance between wild and cure plasmid bacteria, the wild one had different antibiotic MIC values for Nitrofurantoin and Trimethoprim/Sulfamethoxazole (<=16 and <=10 µg/ml) respectively), on the other hand for the same antibiotics, the MIC results for plasmid-cured bacteria were 64 and 80 g/ml. Based on the findings, we can conclude that plasmid genes play a significant role in Pediococcus pentosaceus to resist lead, and there is a strong correlation between antibiotic resistance and lead resistance.

Published: June 2022

Arbuscular mycorrhizal fungi (AMF) are an important form of symbiosis between fungi and plants in an ecosystem. One of the medicinal plants used by the people in West Papua is kebar grass (Biophytum petersianum Klotzsch.). This study aims to determine the AMF association in the rhizosphere of B. petersianum in grasslands. Survey method was used in this study. The presence of AMF was observed by examining root colonization and spore diversity. The results showed that the percentage of AMF colonization in roots was between 46.7–90.0% with an average of 71.66%. Meanwhile, the number of spores found in the plant rhizosphere averaged 119.8 spores per 10 grams of soil sample. There were 18 species of AMF dominated by the genus Glomus (7 species), Acaulospora (3 species), while the genus Claroideoglomus, Entrophospora, Gigaspora, and Scutellospora were dominated each with 2 species. This finding is the first record on the presence of AMF on B. petersianum in West Papua.

Published: June 2022

This study aimed to investigate chromosomal aberrations of Eurycoma longifolia Jack (EL) root extract in human lymphocytes in vitro. Human whole blood was cultured in medium solution that treated with distilled water, 20% DMSO, extract of EL roots at the concentration of 2.5, 5, 10, 20, 40, 80 µg/mL (extracted with distilled water and ethanol), and nontreated (blank: only culture medium and whole blood). All experiments were cultured for 72 hours in the 37°C incubator. The effects of EL roots extract on cytotoxicity were compared with the control groups including the blank, distilled water, and 20% DMSO. This study found that EL root extract significantly decreased metaphase cell number and increased chromosome aberrations dose dependent manner (p<0.01). The 7 types of chromosome aberration that were observed consisted of dicentric chromosome, single chromatid breaks, isochromatid break, isochromatid gap, single chromatid gap, fragmentation, and deletion. The dicentric chromosome was the most common chromosomal aberrations type that was treated with EL root extract both distilled water and ethanol. Moreover, the ethanolic extract of EL root was more effective to stimulate chromosome aberrations compared to the water extract of EL root (the deletion and fragmentation were not found in the water extract of EL root). This study demonstrated that the phytochemicals of EL root extract had cytotoxicity effect (decreased metaphase cells and increase cells death) and genotoxic effect (increased chromosomal aberrations. The use of EL root crude extract with distilled water is therefore safer for cells. However, when EL is used at high levels, it may lead to the inhibition of cell division process and cause side effects (toxicity). EL extracts consist of various phytochemicals with different properties and dosages, thus more studies should be conducted on the effect of those substances on cytotoxicity, especially their effects on genotoxicity humans.

Published: June 2022

The artistic contestation between choral culture and folk song is an important concern in the study of musicology. The problem that is of concern in this study focuses on singing behavior in singing hybrid vocal music. Choir singing behavior has standard vocal techniques, on the other hand the context of understanding folk songs includes natural singing expressions from an ethnicity without being overshadowed by good vocal techniques. The study aims to reconstruct the practice of artistic requirements in Indonesian folksong choir competitions. The study is important because there is artistic contestation between choir culture and folk songs culture leading to a good hybrid performance in the Folklore category. This research method takes material from singing events through observations and studies of audio-visual documentation that are observed repeatedly. This study uses a performance centered approach study that concentrates on the choir's performance. Descriptive-analytic analysis is used as a consequence of the material of the event‘s  that relies on careful descriptions. The results of this study indicate, firstly the choirs which sang folk song repertoire are a hybrid performance characteristic.  Second, the relationship that occurs between artistic requirement and the reality of performances on stage occurs in a multidimensional manner. It was found that there was an adjustment to standardization in the perspective of the coral setting. Third, an understanding of the performance practice as multidimentional and hybrid with artistic requirements shows that a small portion is given to other dimensions (kinesthetic & visual).The findings can be used to reformulate artistic requirements entailing a bigger cultural aspect of folk songs.
Evaluación de impacto del financiamiento educativo en una universidad de Venezuela. Un análisis de regresiones discontinuas sobre la deserción y la graduación
Authors: Hernández-Medina Patricia , Ramírez-Torres Gabriel
Published: June 2022

La presente investigación evaluó el impacto del programa de ayudas económicas de la Universidad Católica Andrés Bello, Caracas, Venezuela, sobre la deserción y el egreso. Se empleó el diseño de regresiones discontinuas difusas para tratamientos múltiples con cuatro puntos de corte en la variable de asignación (índice de ayuda). Los resultados obtenidos muestran que los efectos marginales sobre los distintos tipos de deserción son significativos y presentan los signos esperados (negativo). Un aumento del 1% en el descuento de la matrícula reduce la deserción temprana en aproximadamente 1% y 0.5% la deserción tardía; mientras que eleva en 0.6% la tasa de egreso. La evidencia pareciera mostrar que se requiere introducir cambios en el programa en términos de los criterios de asignación y los montos de apoyo económico.

Published: June 2022

The bacteria were isolated from the soil samples that were collected in oil spill-contaminated sites located at Kamarajar port in Ennore, Chennai, Tamil Nadu, India. The main aim of this study was to isolate the bacteria that produce biosurfactants from the oil spill contaminated soil in Ennore, Chennai and to produce a growth medium for the bacteria to enrich the growth of the bacteria. For the growth of bacteria, Minimal Medium (MM) and Mineral Salt Medium (MSM) were the two types of growth enrichment medium used and serial dilutions of the bacterial cultures were done for the production of colonies. The objective of the study was to perform tests to identify whether the bacteria can be able to produce the bio-surfactant or not. Tests like Drop collapse method and oil displacement method were done to check for the production of biosurfactant. The bacteria which produce the surface active substances were the one which produces the bio-surfactant. As a result, gram staining was done for identifying the nature of bacteria. Most of the gram positive bacteria are known to have the properties of bio-surfactant. These bacteria has peptidoglycan outer layer that are easier to kill - their thick peptidoglycan layer which absorbs antibiotics and cleaning products easily. Hereby we conclude that the bacteria which produces the biosurfactant is Bacillus and further studies should be done on identifying the bacteria at the species level. Therefore, this study was done to eradicate the oil spill contaminated areas with the help of bacteria in a natural way without harming the environment. Bacillus sp. is a gram-positive bacteria which helps in, liver and renal function, and act as an inflammatory markers and in maintaining blood glucose levels. It does not have an outer cell wall and only has a membrane of peptidoglycan which makes the Bacillus more absorbent and eco-friendly.

Authors: Sarmiento Aponte Ingrid
Published: June 2022

En los últimos 100 años ha venido aconteciendo un resurgimiento de la filosofía en escenarios sociales, fenómeno al que se ha denominado el “giro práctico” de la filosofía. Este “giro práctico” de la filosofía se constata con el surgimiento de una serie de prácticas filosóficas en distintos momentos y lugares del mundo a lo largo del siglo XX: los diálogos socráticos, la Filosofía para Niños, los Talleres de filosofía, la filosofía para organizaciones, la consultoría y los cafés filosóficos, entre otros. Estas prácticas comparten una concepción muy cercana de la filosofía y su valor. Ante el presente panorama, el siguiente artículo indaga: 1) por las razones que han llevado a que estas prácticas sean acogidas y tengan cada vez mayor aceptación entre el público no especializado en este campo del saber; 2) la respuesta de la academia especializada en filosofía ante esta demanda social; 3) el giro práctico de la filosofía en la escuela en cuanto escenario social y; 4) las posibilidades formativas y de acción que se abren al profesional de filosofía que se aproxima y ejerce en estos campos emergentes de actuación.

Published: June 2022

In 2006, Egypt issued new standards to be in line with the International Financial Reporting Standards (IFRS). The new Egyptian Accounting Standards (EAS) were created with the intention of making financial statements more comparable and transparent, and they replaced the country’s previous 1997 and 2002 standards. This study aims to investigate how these new modifications of the EAS affect the market volatility (MV) and earnings quality (EQ) in such a developing country. Using data from 184 observations from 46 non-financial Egyptian listed firms for the period from 2013 to 2018, our results show that IFRS convergence has no effect on EQ (Mahmoud, 2018; Osinubi, 2020). Earnings quality is also found to be inversely related to MV (Hung & Van, 2020; Wongchoti, Tian, Hao, Ding, & Zhou, 2021), and IFRS has a significant positive impact on MV. The results also confirm no change in EQ and MV after the new EAS. These findings can guide standard setters and regulators that applying high-quality financial standards is not solely sufficient to provide accurate information and that other factors, such as legal enforcement, organization performance, and increasing the cost of compliance, are needed alongside post-IFRS convergence.
Refining Geomorphic Heterogeneity as a Framework for Assessing River Corridor Processes and Characteristics
Authors: Scott Daniel , Shahverdian Scott , Flitcroft Rebecca , Wohl Ellen
Published: June 2022

Spatial and temporal heterogeneity, or messiness, is a broadly desirable
characteristic of river corridors and an indicator of many of the
geomorphic processes that sustain fluvial ecosystems. However,
quantifying geomorphic heterogeneity is complicated by a lack of
consistent metrics, classification schemas for dividing the river
corridor into the patches that form the basis for those metrics, and
guidance on interpreting metrics. Drawing from both geomorphic and
landscape ecology concepts, we offer ideas and guidance intended to help
investigators, from researchers to restoration practitioners, more
effectively and reliably use heterogeneity to describe river corridor
processes and characteristics. We define geomorphic heterogeneity both
spatially and temporally. Spatially, heterogeneity can be described by
diversity, or the evenness and richness of geomorphic units, and spatial
configuration, or the arrangement and shape of geomorphic units.
Temporally, heterogeneity can be described by turnover rate, or the rate
of change of geomorphic units. Interpretation of heterogeneity metrics
depends integrally on the definition of the geomorphic unit schema on
which metrics are based. Contextual information, such as measurements of
process space (i.e., how much room a river has to move), disturbance
frequency, and geomorphic trajectory, can also be key to interpreting
measurements of heterogeneity. Geomorphic applications of heterogeneity
require carefully defined geomorphic unit schemas that reflect processes
and characteristics of interest, robust metrics of heterogeneity whose
meaning is appropriate to the question at hand, and interpretation of
those metrics based on the context of expected geomorphic processes and
the disturbance regime.

Published: June 2022

Inferior vena cava thrombosis (IVCT) is a rare occurrence and is a
result of leg deep vein thrombosis (DVT). The etiology of IVC thrombosis
can be divided into congenital versus acquired etiological factors found
in Virchow’s triad of stasis, injury, and hypercoagulability.
Hyperhomocysteinemia is a rare risk factor for thromboembolism.
Intraoperative Ventricular Septal Rupture: A Case Report
Authors: Rando Hannah , Kilic Ahmet
Published: June 2022

Ventricular septal rupture (VSR) is a rare complication of myocardial
infarction that requires surgical repair. Herein we describe a case of
intraoperative VSR requiring a second bypass run and patch repair. This
case highlights the importance of early reperfusion and poses concern
for delayed patient presentation during the COVID-19 pandemic.
The association between household food security and the type of farm power used in land preparation

Climate change is undermining food security in sub–Saharan Africa (SSA)
where its impacts are disproportionately felt. Although agricultural
mechanization has received attention in SSA over the years as a key
pathway for improving agricultural productivity, its links with food
security among smallholders remain unclear. In this paper, we examine
the association between household food security and the type of farm
power for land preparation among smallholders (n=1100). The findings
suggest that households that used tractors for land preparation were
more likely (OR=1.43, p≤0.05) to report food security when compared to
households using manual tools. We also highlight some caveats and policy
recommendations.

Published: June 2022

In this study, the CeO2-WO3/TiO2-n catalyst was synthesized by
co-precipitation method with citric acid and the selective catalytic
reduction (SCR) performance of citric acid modified CeO2-WO3/TiO2
catalyst was studied. The results demonstrated that compared with
CeO2-WO3/TiO2 catalyst, CeO2-WO3/TiO2-6% catalyst has been widened
about 30°C in the temperature range of 80% and 90%, respectively, and
the highest denitration efficiency was 98.83% at 350°C. Additionally,
citric acid formed complex with WO3 and CeO2 and three carboxylic acid
groups can improve the stability of WO3 to inhibit the growth of TiO2
and CeO2 crystallites, thus promoting the dispersion of CeO2 and the
formation of Ce-O-W solid solution. Furthermore, the strong interaction
between CeO2 and WO3 in CeO2-WO3/TiO2-6% catalyst will release more Oα
and Ce3+. Citric acid promoted the interaction of unsaturated W atoms
and hydroxyl groups adsorbed on unsaturated W atoms, thus providing more
Lewis and Brönsted acid sites on the catalyst surface
Dependência, contrarreforma e violência agrária na América Latina
Authors: Silva Emerson Neves da
Published: June 2022

A América Latina, no século XXI, configura-se em um território que protagoniza a ascensão de governos progressistas, caracterizados pelo estabelecimento de políticas reformistas nas áreas sociais e econômicas, como, por exemplo, a ampliação do mercado consumidor interno e o controle dos recursos naturais nacionais para o desenvolvimento de políticas públicas, atenuando a relação histórica de dependência da região. A partir desse processo histórico, o presente trabalho analisa a reação das classes dominantes regionais e do capital globalizado, denominada de movimento contrarreformista, responsável pela promoção de governos conservadores e neoliberais. A experiência brasileira é abordada enquanto estudo de caso do contrarreformismo na América Latina, destacando o aumento da violência no campo em virtude da intensificação dos conflitos agrários. A teoria marxista da dependência é a abordagem teórica utilizada para a compreensão da gestação do contrarreformismo e do neoliberalismo, bem como o recrudescimento da luta social, sobretudo no campo brasileiro.

The source base of the book includes materials from Russian and German archives, documentary collections, memoirs, and publications on the subject under research. Thanks to this, the author was able to show that the solution of the German question was possible not only due to the external and internal factors but also due to the political will of Helmut Kohl.
Taxonomic diversity of phytoplankton of the Kalmius River and its reservoirs
Authors: Mirnenko Eduard I.
Published: June 2022

The paper presents data on the taxonomic diversity of phytoplankton in the middle section of the Kalmius River and the reservoirs located on it. Floristic analysis showed the presence in the aquatic biocenosis of 291 species of algae and 162 intraspecific taxa belonging to 8 divisions, 18 classes, 42 orders, 66 families and 105 genera. The divisions Cyanophyta, Chlorophyta, and Bacillariophyta dominated in frequency of occurrence. The Shannon-Weaver index varied the most in the Starobeshevsk Reservoir. The Sorensen-Chekanovsky coefficient evidences the isolation of the phytoplankton algal flora of the Starobeshevsk Reservoir. In the Nizhnekalmius Reservoir, a regular annual repetition of the dominant types of algoflora development has been established.
