Published: March 2022

ABSTRACT Considering the importance of identifying Colletotrichum species associated with cotton plants, this study aimed to characterize the morphological and pathogenic isolates of C. gossypii var. cephalosporioides and C. gossypii under different temperatures. Five isolates of C. gossypii var. cephalosporioides and C. gossypii were incubated at 20, 25 and 30 °C. The cultural characteristics data were analyzed through ANOVA and the means compared by the Tukey test. There were differences between the isolates of the two species concerning mycelial growth and sporulation at different temperatures. Temperatures between 20 to 30 °C increased the length of conidia but did not influence the width, whereas between 25 and 30 °C, there was the highest mycelial growth. Colletotrichum gossypii expressed anthracnose symptoms, and ramulosis symptoms were observed only in plants inoculated with C. gossypii var. cephalosporioides.

Published: March 2022

ABSTRACT Controlled water deficit in the phenological phases of cherry tomato can be used without significantly impairing crop yield. The objective was to determine the coefficients of sensitivity to water deficit in cherry tomatoes and to understand the effects of this deficit in agronomic variables and water use efficiency for different irrigation strategies based on phenological stages. The experimental design used was randomized blocks in a split-plot scheme, with four replicates. The primary treatments distributed in the plots were as follows: control without induction of water deficit (W1) and induction of water deficit in the vegetative stage (W2), in the flowering stage (W3), in the fruiting stage (W4), in the maturation stage (W5), and in all phenological stages (W6). The secondary treatments comprised two cherry tomato cultivars, orange and red, placed in the subplots. Water deficit was established at 50% of crop evapotranspiration. Cherry tomato is recommended for production in semiarid regions owing to their adaptability to controlled water deficit based on the coefficient of sensitivity to water deficit, which assists in the management of water resources for irrigation and the maintenance of crop productivity. The vegetative stage is recommended for the deficit irrigation strategy. However, water deficit should not be implemented in the flowering stage, which is considered the most critical stage for the application of water deficit in both cultivars.

ABSTRACT The objective of this study was to evaluate the performance of the AquaCrop model in the estimation of grain yield and crop water yield for nine hybrids of corn with different irrigation strategies in the municipalities of Santiago, Chile, and Alegrete, in the western region of the state of Rio Grande do Sul, Brazil. Data on climate, soil, management and crop yield over four crop seasons (2015 to 2019) were used, the first two in Santiago city, and the third and fourth in Alegrete city. The experimental design was randomised blocks, consisting of five irrigation treatments (0, 50, 75, 100 and 125% of crop evapotranspiration), and four, six and one hybrid, respectively, for the first, second and third growing season. In the fourth crop season, one hybrid was considered and the treatments consisted of suppression in water supply to the crop during its reproductive period, corresponding to ETc during vegetative (ETcVeg.) and reproductive (ETcRep.) phases, as follows: 0, 50Veg./25Rep., 75Veg./37.5Rep., 100Veg./50Rep. and 100% of ETc. The performance of the model, evaluated through statistical indicators, was “excellent” and “good” for the simulation of grain yield and crop water productivity, respectively. There was a tendency of the model to overestimate the results under conditions of water deficit, this being more pronounced under severe deficit than under mild deficit, or in the reproductive period of the crop, and a tendency to underestimate the results under conditions of irrigation without deficit, i.e., 100 or 125% ETc.
PERCEPTIONS AND WILLINGNESS OF BRAZILIAN FEDERAL DISTRICT FARMERS REGARDING PAYMENT FOR USE OF WATER RESOURCES
Authors: Ferreira Adriane Furlan Alves , Oliveira-Filho Eduardo Cyrino
Published: March 2022

Abstract Although it has already started in some states, charging for the use of water resources is not yet widespread in Brazil. The aim of this research was to know the perceptions and willingness of farmers in relation to payment for the use of water resources, to make it feasible to collect this fee, introduced by Law No. 9,433, of 1997-Brazilian National Policy of Water Resources (PNRH). In this context, we sought to obtain this knowledge through qualitative research and a semi-structured survey applied to 37 farmers from five hydrographic basins in the Brazilian Federal District. The results, using Iramuteq software, showed the lack of motivation to pay for use of water resources, but also made it clear that the negative situational motivation can be modified if the State intervenes to meet both demands for information and questions raised, in order to bring their motivations, attitudes and sustainable behaviors to light.
Prevalence of binge drinking among medical students in Brazil: A systematic review and meta-analysis
Authors: Nascimento Maria Isabel do , Costa Juliana dos Santos , Andrade Carlos Augusto Ferreira de
Published: March 2022

Abstract: Introduction: Binge drinking consists of an alcohol consumption pattern that is dangerous for the drinkers and for society. Undergraduate medical students are often exposed to stressful situations, increasing the propensity for psychoactive substance use including excessive alcohol consumption. Objective: The aim of this study was to develop a systematic review and meta-analysis to estimate the pooled prevalence of binge drinking practiced by Brazilian medical students. Methods: The search was performed in a standardized way, involving two researchers, and by consulting the PubMed/Medline, SciELO and LILACS databases. A meta-analysis was carried out to estimate the pooled prevalence of binge drinking and 95% Confidence Intervals (95% CI). Results: We identified 206 records and included 14 studies in the review. The combined prevalence was estimated by the random effect method. Despite the substantial heterogeneity among the studies, the pooled analysis indicated that binge drinking is practiced by 47% of medical students as a whole, in Brazil (95% CI: 38%; 57%), and by 65% (95% CI: 50%; 78%) and 47% (95% CI: 34% to 59%), considering men and women, respectively. Conclusion: Binge drinking is practiced by almost half of the contingent of our future doctors. These results provide insights as to the choices and decisions that these students make regarding the consumption of potentially dangerous substances for the human health. Despite the high heterogeneity, the magnitude of the binge-drinking problem estimated in this meta-analysis demands an effective involvement of medical schools in Brazil.

Abstract: Introduction: Since the National Curricular Guidelines for the Medicine course were implemented, with emphasis on the training of professionals with a generalist profile, the factors that may contribute to the interest in professional practice are unknown. Objective: This study aimed to analyze the perception of medical students regarding their generalist training and the factors that influence the desire for professional practice. Methodology: Descriptive and analytical cross-sectional study of qualitative and explanatory character with 523 students from different medical courses in the city of Salvador-Bahia, who answered an online survey after signing the informed consent form. The sample was categorized into interest in Immediate Specialization (IS) and among those who intend to Act as a Generalist (AG). The age and period of the course were also categorized into groups. Results: The age of the sample was 18 to 25 years in 83.7% (n = 438), with 72.5% (n = 380) being female, attending 69% of the 4º to 9º semesters (n = 363). The Immediate Specialization group represented 27.2% (95% CI: 35% -73%) and the group that intends to Act as a Generalist, 72.8% (95% CI: 68% -76%). General training did not influence the option for professional practice with RR = 0.81 (95% CI: 0.55-1.20) p = 0.308. The factors associated with AG were believing in the generalist’s resolution capacity and SUS guidelines (p <0.001), the desire to contribute to society (p = 0.005) and society’s credibility (p = 0.044). Conclusion: Students perceive that the curriculum includes general training, however it did not influence the interest in professional practice. The desire to act as a generalist is present in a significant number among them, driven by altruism and the desire to contribute to society, supported by the organic laws that underlie the SUS Guidelines, while not feeling valued and having its credibility, questioned by society, only stimulates professional practice on a temporary basis.
DOES ACQUISITIONS IMPACT THE FIRM’S TECHNOLOGICAL DEVELOPMENT? A STUDY USING KNOWLEDGE BASE IN THE PHARMACEUTICAL INDUSTRY
Authors: Matos Murilo Montanari de , Avellar Ana Paula Macedo de
Published: March 2022

ABSTRACT This article focuses on the acquisition of small pharmaceutical firms (SPHF) by large pharmaceutical firms (LPHF). LPHFs enlarge their own knowledge base by incorporating their target’s knowledge base. Given this scenario we pose the question: Is it possible to link knowledge acquired via an acquisition to technological development? In order to answer this question we developed an approach that allows the impact of a target’s knowledge base to be observed in the acquirer’s own knowledge base. This objective was achieved qualitatively, based on a sample of 8 LPHFs and 51 SPHFs. Our main conclusions were: (i) the dissemination of biotechnologies is boosted by acquisition; (ii) acquisitions have allowed the knowledge bases of LPHFs to assimilate their target’s knowledge bases; (iii) the target’s patents offer a great potential for developing technologies that are already dominated by the LPHF; and (iv) the “incorporation” of scientists from target companies allows LPHFs to internalize research lines. Our main contribution is to link knowledge base characteristics to potential directions taken in the technological development process.

RESUMO Relata-se pesquisa com professores sobre os sentidos de trabalho pedagógico na escola. Como técnicas de produção de dados, aconteceram entrevistas e pesquisa bibliográfica. Toda a pesquisa teve como fundamento teórico-metodológico a análise de movimentos de sentidos, que consiste no estudo aprofundado e comparativo dos discursos, visando a esclarecer os sentidos, os quais constituem as categorias analíticas. Na medida em que se aborda a pesquisa, também se descreve e indica como proceder na análise dos movimentos de sentidos na pesquisa em educação. A análise possibilitou, além do aprofundamento das categorias, compreender que os professores, sujeitos sociais, cuja historicidade e trabalho pedagógico produzem-se cotidiana e coletivamente, no ambiente, específico e dinâmico da escola, em seus discursos, denotam obnubilamento da compreensão de si e do seu trabalho, por não terem mais o tempo e o espaço para discursivá-lo.

Authors: Moura de Almeida Carolina Bittencourt , Guimarães Gotardo Daniela Rosa
Published: March 2022

INTRODUCTION: The clinical interview is an essential procedure in the process of the clinical encounter, of care whenever the doctor behaves with a capacity for respect, interest, authenticity, coherence and empathic understanding. Anamnesis favors the recognition of others, their needs, fears and anxieties. Based on these reflections, we assessed the need to offer an extension course on the construction of anamnesis, in digital format, at the State University of Bahia (UNEB), which addresses issues and which equips students so that they have the necessary knowledge to face the consequences caused by the pandemic COVID-19, and the absence of face-to-face higher education classes in the State of Bahia. OBJECTIVES: To develop a set of knowledge that lead to the sedimentation of the construction of the clinical history (anamnesis) and exploration of the main signs and symptoms. METHODOLOGY: The course was executed entirely on the Google classroomÒ / MeetÒ platform in 09 meetings, from 18/08 to 14/10 2020, with 24 students enrolled and divided into 2 classes of 12 students. The methodology included synchronous activities (theoretical classes and discussions) and asynchronous activities (video lessons available on the platform, support material and activities for home). The theoretical evaluation was performed using the googleforms form, as well as the course evaluation research form. CONCLUSIONS: The evaluation made by the students brought feelings of thanks, enchantment and fulfillment for participating in a course focused on Medical Semiology, as it was the first contact with the Medical Course for some of the students. In view of the results, and the reflection of the teachers, there was a desire to repeat the extension course, especially for newly enrolled students, as they realized the importance of such an activity during this period of uncertainty.
Эффективность городского соуправления в региональных городах России (на примере Якутии)
Authors: Титов Эдуард Александрович
Published: March 2022

В последние десятилетия происходит трансформация моделей управления городами. На смену urban government («городское правительство», «городское управление») приходит концепция urban governance («городское соуправление»), в которой границы между государственным и частным секторами размываются, а управление сосредотачивается на механизмах, которые не опираются на исключительную власть городской администрации. На передний план выходит способность реализовывать коллективный поиск решения проблем, привлекать новых акторов и осваивать новые формы взаимодействия. Одними из главных стейкхолдеров в модели городского соуправления выступают горожане и частный бизнес. Вопросы участия горожан и бизнеса в принятии решений, организация и поиск эффективных механизмов являются важной областью изучения городского соуправления.Однако исследуется городское соуправление и опыт внедрения его принципов в основном в зарубежных странах (опыт городов США, Европы, Южной Африки и др.) — российский опыт до сих пор остается малоизученным. В настоящей работе исследуется текущее состояние развития городского соуправления в городах России на примере Республики Саха (Якутия). Используются экспертные интервью и индекс городского соуправления, а само изучение ведется с точки зрения общественного участия в управлении городами и роли городских органов власти в этих процессах. В статье также оценивается готовность местных органов власти к вовлечению населения и частного бизнеса в управление городами Якутии и анализируется влияние размера города на эффективность принципов городского соуправления. Результаты исследования показывают, что в городах Якутии только начинают реализовываться принципы городского соуправления (чаще всего коллаборативные отношения развиваются в сфере благоустройства общественных территорий), при этом органы городской власти проявляют низкую активность в построении горизонтальных связей. Кроме того, в малых городах городское соуправление реализуется эффективнее, чем в крупных городах.

Effect of maturity accelerants on the postharvest behavior of avocados (Persea americana Mill.) cv. Lorena
Authors: Alvarez-Herrera Javier Giovanni , Jaime-Guerrero Marilcen , Reyes-Medina Andrea Johana
Published: March 2022

The global demand for avocados has grown in recent years. In Colombia, the Lorena variety is widely accepted in the market but the challenge for consumers is determining when the fruits should be consumed. However, there are no studies on this matter because most research is done on the Hass variety, which dominates global production. Therefore, the objective was to evaluate ripening treatments in Lorena variety avocado fruits to establish the postharvest behavior, avoid quality losses, and maintain organoleptic characteristics, facilitating commercialization of the product. A randomized complete block design was used with two blocks (maturity I and maturity II), five maturation treatments, three ethylene applications (2, 4 and 6 mL L-1), fruits wrapped in unprinted newspaper, and a control. The fruits reached 16 days after harvest (dah) with commercial quality. The application of 6 mL L-1 of ethylene presented the greatest mass loss. At 6 dah, the climacteric peak presented with the highest values of soluble solids, maturity index (MI), and loss of firmness and the lowest percentage of total titratable acidity (TTA). The TTA had higher values for the control treatment during storage. The MI registered two maximums during postharvest: the first in the climacteric peak, and the second during fruit senescence.
Advances in Hass avocado irrigation scheduling under digital agriculture approach
Authors: Erazo-Mesa Edwin , Echeverri-Sánchez Andrés , Ramírez-Gil Joaquin Guillermo
Published: March 2022

Under tropical conditions, Hass avocado irrigation is a controversial issue due to insufficient scientific evidence. The rapid progression of technological advances and its incorporation in agriculture have expanded options to improve the irrigation scheduling (IS) of Hass avocado. The concept featuring those technological advances in agriculture is digital agriculture (DA). Here, we present a mixture of well-known studies in the Hass avocado irrigation focused on proximal sensing (PS) technologies and recent studies emphasizing the potential of remote sensing (RS), and application technologies to schedule the irrigation. PS takes advantage of the soil or trees' proximity to output reliable measurements with a high temporal resolution, while RS provides a broad set of spectral data in continuous and large areas that can be transformed into crop-related biophysical variables. Applications – a term grouping mobile (smartphone) apps, desktop programs, and web-based platforms – offers portability, high precision, and graphic visualization of variables obtained or estimated by sensors. Integrating RS and PS technologies through user-friendly applications can represent a suitable option to improve Hass avocado irrigation in developing countries. Our review is presented in the following sections: general introduction, DA approach definition, use of proximal sensing, use of remote sensing, and scheduling irrigation applications.
Optimal Control of Transfer to Vertical Orbits from Lyapunov Orbits Using Low-Thrust Engine
Authors: Chongrui Du , Starinova O. L.
Published: March 2022

There are many different families of periodic orbits in the Earth-Moon system, such as Lyapunov orbits, halo orbits, vertical orbits, etc. The establishment of a lunar space station requires a spacecraft to be able to transfer among these orbits. Lyapunov orbits have been used by some missions and are well-studied orbits, while periodic vertical orbits can provide large amplitudes of spacecraft motion outside the plane of the Moon’s motion, which makes it possible to avoid shadowing of the orbits and use them as relay satellite in cislunar space. Modern researchers mainly consider the use of high-thrust engines for transfer. With the development of electric propulsion technology, the use of low, but long-acting thrust for deep space exploration has become especially relevant. This is due to the high specific characteristics of the propulsion systems of this type. In this article, an algorithm has been developed for determining the optimal control with a low-thrust engine for a transfer from Lyapunov orbit to a vertical orbit. The minimum time of flight or the minimum costs of the working body are used as criteria for optimality. In the calculation for solving the two-point boundary value problem of the optimal control theory, the parameter continuation algorithm is used, which allows to gradually get the transfer from some simple results to the final transfer trajectory. The results obtained make it possible to assert that the use of intermediate axial orbits allows the use of propulsion systems with lower thrust levels. In this case, the duration of the flight increases slightly with an almost unchanged consumption of the working body. Moreover, the homotopy method makes it possible to reduce the consumption of working body, while the control of the engine throttling becomes discrete. The results of this study and the algorithms proposed in this article can be used to determine the optimal program control and ballistic design of lunar missions.

AIM: To identify and describe micro- and ultrastructural thermally induced changes in Bakers cyst wall associated with the duration of unidirectional uniform heating at 70C.
MATERIALS AND METHODS: We took one full-thickness fragment from each of the 15 Bakers cysts excised during the operation and divided each fragment into four parts: one was used as a control sample, and the remaining three fragments were placed with the synovial membrane on a thermostat heated to 70C, with exposure times of 60, 120, and 180 seconds. We used light-optical and electron microscopes for the histomorphological examination of the samples.
RESULTS: Two layers of Bakers cyst wall were identified: inner (synovial) and outer (fibrous). In samples exposed to heat for 60 seconds, the synovial layer was undamaged. In samples exposed to heat for 120 seconds, thermal damage to the cells of the synovial layer and underlying collagen fibers of the fibrous layer was evident. With a heating duration of up to 180 seconds, histomorphological examination revealed signs of damage reaching the middle of the fibrous layer, and signs of deep disorganization of the collagen fibers of the cyst wall were determined at the electron-microscopic level.
DISCUSSION: Using light microscopy of intact sections of the cyst wall, we, like other researchers, identified two layers (synovial and fibrous) of different densities, with blood vessels passing through them. The performed experiment suggests that a clinically significant result using Bakers cyst thermotherapy is achieved when spreading the zone of irreversible coagulation beyond the middle of the fibrous layer of the cyst wall. This, in turn, guarantees damage to the capillary network that provides trophism and proliferation of synoviocytes. The proposed hypothesis corresponds to the paradigm of similar studies on the coagulation of cysts of other localizations.
CONCLUSION: The obtained results of the light-optical and electron-microscopic examination of Bakers cyst wall fragments indicate direct dependence of the depth of thermal coagulation on the duration of heating.
Polyostotic fibrous dysplasia: imaging findings of a controversial case
Authors: Guglielmi Giuseppe , De Michele Francesca , Carpagnano Francesca A. , Paparella Maria  T.
Published: March 2022

Fibrous dysplasia is a rare non-neoplastic tumor-like congenital bone disease that is most likely associated with GNAS gene mutations, with a broad spectrum of clinical presentations, ranging from isolated monostotic and polyostotic forms to other extra-skeletal associated manifestations as in McCuneAlbright syndrome. It is responsible for bones weakening and increased fragility, making it prone to fractures.
A 65-year-old female patient was referred to our radiology department for cervical and dorsal pain, with a previous diagnosis of incidental cervical and dorsal bone lesions that are suspected for metastases. X-ray, computed tomography, and magnetic resonance imaging were performed with a precise diagnostic suspicion of fibrous dysplasia that is confirmed by bone biopsy.
Fibrous dysplasia principally affects the bone and is characterized by bone replacement itself by dysplastic fibrous tissue. According to the number of affected bones and their association to endocrine alterations, it is classified into three categories monostotic, polyostotic, and Albrights disease. Differential diagnosis with multiple myeloma among others and the best treatment decision was made.
Unilateral isolated fracture of the pterygoid plate: a case report
Authors: Balzano Rosario Francesco F. , Testini Valentina , Cammarota Aldo , Guglielmi Giuseppe
Published: March 2022

Pterygoid plate fractures are often associated with Le Fort fractures and accompanied by other facial fractures such as frontal sinus and naso-orbital-ethmoid fractures; isolated pterygoid plate fractures are extremely rare.
Le Fort fractures must be surgically treated with fixation of unstable fracture segments to re-establish bone form and function, and the pterygoid process must be surgically stabilized; however, surgical treatment is unnecessary in isolated pterygoid plate fractures.
Here, we report a rare case of isolated unilateral fracture of the pterygoid process in a 71-year-old female patient who had a syncopal episode with secondary head injury and a hematoma at the base of the right orbit.
A computed tomography scan showed unilateral right pterygoid plate fracture with signs of emphysema in the ipsilateral masticatory space. The patient also had a fracture of the medial wall of the right maxillary sinus with hemosine, but no fractures of the skull base or theca. She was treated conservatively.

Integrated Seismic Program (ISP) is a graphical user interface designed to facilitate and provide a user-friendly framework for performing diverse common and advanced tasks in seismological research. ISP is composed of five main modules for earthquake location, time–frequency analysis and advanced signal processing, implementation of array techniques to estimate the slowness vector, seismic moment tensor inversion, and receiver function computation and analysis. In addition, several support tools are available, allowing the user to create an event database, download data from International Federation of Digital Seismograph Networks services, inspect the background noise, and compute synthetic seismograms. ISP is written in Python3, supported by several open-source and/or publicly available tools. Its modular design allows for new features to be added in a collaborative development environment.
Slip Kinematics of the 2021 Yangbi Earthquake: Fore-Main-Aftershock Sequence Rupture along an Unknown Secondary Fault of the Weixi–Qiaohou Fault
Authors: Li Chenglong , Shan Xinjian , Zhang Guohong , Zhao Cuiping , Gong Wenyu , Zhang Yingfeng
Published: March 2022

On 21 May 2021, an earthquake sequence occurred at the Weixi–Qiaohou fault that is considered as a boundary of the Chuandian block in Southwest China, providing a significant opportunity to understand the seismogenic tectonics of the fault and its secondary faults. We used Interferometric Synthetic Aperture Radar and Global Navigation Satellite System observations to obtain surface displacements and slip kinematics of the Mw 6.1 mainshock. The Mw 6.1 event ruptured along a previously unknown secondary fault of the Weixi–Qiaohou fault; this newly identified southwest-dipping fault is dominated by right-lateral strike slip with a small normal component. Fault slip was concentrated between depths of 3 and 8 km, with a maximum slip of ∼0.8 m. Given that there is minor slip and lack of foreshocks and aftershocks rupture in 0–3 km depth, a systemic shallow slip deficit is observed in the depth. In addition, stress change simulations suggest that the Mw 5.4 foreshock promoted the Mw 6.1 event. The increased coulomb stress change region extends approximately 16 km (from 25.65° N to 25.52° N) along the Weixi–Qiaohou fault triggered by the Mw 6.1 mainshock. Combined with modeling results of the Yangbi earthquake sequence and magnetotelluric model across the Weixi–Qiaohou fault, the fore-main-aftershock sequence initiate in depths of 8–16 km (corresponding to relatively low resistivity) and further promote larger slip upward along depths of 3–8 km (relatively high resistivity). Finally, aftershocks rupture and release stress below slip depths of the mainshock.
Testing a Prototype Earthquake Early Warning System: A Retrospective Study of the 2021 Mw 7.4 Maduo, Tibet, Earthquake

Published: March 2022

On 21 May 2021, an Mw 7.4 earthquake occurred in Maduo County, Qinghai Province, China. A dense network of high-rate (1 Hz) Global Navigation Satellite System (GNSS) stations around the epicenter provided one of the most complete recordings of GNSS kinematic displacements in Tibet to date. We used these data retrospectively to test a prototype earthquake early warning (EEW) system. Here, we present the results of that test, in which the EEW system archived high-rate GNSS displacement streams, and then used them to track evolving magnitude and slip. The geodetic module in the EEW system issued the first alert 34 s after the earthquake onset. The first alert had a moment magnitude (Mw) of 6.65, which then increased until reaching a stable value (Mw 7.4) 61 s after the earthquake onset. Testing results show good agreement with rapid GNSS displacements and postprocessed GNSS displacements; moreover, the rapid finite-fault inversion is consistent with postinversion magnitude and rupture dimensions. Our findings confirm the viability and usefulness of this EEW system in quasi-real-time magnitude estimation and finite-fault slip inversion.
Monitoring Operational States of a Nuclear Reactor Using Seismoacoustic Signatures and Machine Learning

Published: March 2022

Monitoring nuclear reactors is an important safety and security task with growing requirements. We explore the possibility of using seismic and acoustic data for inferring the power level of an operating reactor. Continuous data recorded at a single seismoacoustic station that is located about 50 m away from a research reactor was visualized and analyzed. The data show a clear correlation between seismoacoustic features and reactor main operational states. We designed a workflow that includes two machine learning (ML) models to classify the reactor operational states (OFF, transition, and ON) and estimate reactor power levels (10%, 30%, 50%, 70%, and 90%). We applied and compared five ML algorithms for the reactor OFF-transition-ON and four approaches for the power level classification. We also compared the performance of ML models trained with seismic-only, acoustic-only, and both types of data. Five-fold cross validations were implemented to assure a thorough evaluation of the model performances. The results show the extreme boosting gradient algorithm worked best for the first model, whereas random forests performed best for the second model. Combining seismic and acoustic data leads to better performance than using a single type of data. Seismic data contributed more than acoustic data for both models. We reached an accuracy of 0.98 for reactor OFF and ON. The accuracies for the transition state and power levels are less optimal with a minimum accuracy of 0.66. However, our results suggest seismic and acoustic data contain useful information about the transition state as well as power levels. Seismic and acoustic data could be integrated with other observations to improve monitoring performance.

The ever-increasing networks and quantity of seismic data drive the need for seamless and automatic workflows for rapid and accurate earthquake detection and location. In recent years, machine learning (ML)-based pickers have achieved remarkable accuracy and efficiency with generalization, and thus can significantly improve the earthquake location accuracy of previously developed sequential location methods. However, the inconsistent input or output (I/O) formats between multiple packages often limit their cross application. To reduce format barriers, we incorporated a widely used ML phase picker—PhaseNet—with several popular earthquake location methods and developed a “hands-free” end-to-end ML-based location workflow (named LOC-FLOW), which can be applied directly to continuous waveforms and build high-precision earthquake catalogs at local and regional scales. The renovated open-source package assembles several sequential algorithms including seismic first-arrival picking (PhaseNet and STA/LTA), phase association (REAL), absolute location (VELEST and HYPOINVERSE), and double-difference relative location (hypoDD and GrowClust). We provided different location strategies and I/O interfaces for format conversion to form a seamless earthquake location workflow. Different algorithms can be flexibly selected and/or combined. As an example, we apply LOC-FLOW to the 28 September 2004 Mw 6.0 Parkfield, California, earthquake sequence. LOC-FLOW accomplished seismic phase picking, association, velocity model updating, station correction, absolute location, and double-difference relocation for 16-day continuous seismic data. We detected and located 3.7 times (i.e., 4357) as many as earthquakes with cross-correlation double-difference locations from the Northern California Earthquake Data Center. Our study demonstrates that LOC-FLOW is capable of building high-precision earthquake catalogs efficiently and seamlessly from continuous seismic data.

Primary Health Care is the first contact between community and health system. Most of the ailments can be dealt with at this level. So if we know which health problems are more prevalent in community we can improve Primary Health Care.

This is a cross-sectional study conducted at a private clinic at chandkheda, Ahmedabad to determine the prevalence of various common health ailments in the community. Study included 100 patients who presented to OPD during the study period. Their standard of living, level of education and their socio-economic status was also considered and all collected data was statistically analyzed.

In this study, three most commonly observed disorders were respiratory tract infections (URTI) 17%, Cardiovascular disease 12%, and Gastrointestinal disease 12%.

Majority of the diseases in this community can be totally controlled and prevented by taking hygienic measures and modifying their lifestyle, taking medical attention during first onset of symptoms, avoiding self medication, along with social, psychological and spiritual support by treating family physician with adequate information of prescribed medication, health education and follow up.
La desindustrialización argentina en el largo ciclo neoliberal (1976-2001): una aproximación a la trayectoria de las clases y fracciones de clase

Published: March 2022

En 1974 la economía argentina acumulaba una década de crecimiento económico ininterrumpido; desde entonces y hasta comienzos del siglo xxi la misma mostró un desempeño insatisfactorio, especialmente si es comparada con otros países de la región como Brasil y México. El rasgo distintivo de este derrotero radica en un intenso proceso de desindustrialización signado por el largo ciclo neoliberal que inauguró la última dictadura militar argentina en 1976. El objetivo de este artículo es indagar en el desempeño de los principales actores económicos, teniendo en cuenta los cambios en la relación capital-trabajo y las transformaciones que sucedieron dentro de la propia clase capitalista. Para ello, a los aportes realizados por la literatura especializada se le suma un análisis estadístico de las principales variables económicas referidas a la industria y a las grandes empresas del sector.

The presence of gypsum in soil has a high effect on the mechanical and physical properties of soil. This effect depends fundamentally on the type and quantity of gypsum existent in the soil. The present study attempts to improve the physical and mechanical properties of gypseous soil using a new type of pozzolanic material discovered as a pozzolanic material from attapulgite clay. It is called “High Reactivity Attapulgite” HRA. The objective of this study is to investigate the ability of this material to be a moderate stabilizer material used for treating soil. The soil was obtained from one location at depth 1 m with 28% gypsum content. High Reactivity Attapulgite (HRA) was used as a replacement with soil in different percentage (5%, 10%, 20%, and 40%). Experimental tests included Atterberg limits, modified compaction, strength, unconfined compression and consolidation. Then all the tests were conducted on specimens with HRA content that was varied in the range 5-40%. The results showed the important effect of HRA on gypseous soil, as was seen from the reduction in the collapse potential by about 13-90%, and the increase in the unconfined compressive strength from 88 kPa to 271 kPa upon the addition of HRA by 5-40%.

Despite the abundance and varying complexity of valve repair methods as well as the lack of guaranteed positive results, the problem of guaranteed elimination of nasal valve dysfunction remains unresolved. The article discusses the experience of treating a patient with this disease by installing an ALAR nasal valve stent. Previously, the patient underwent a standardized examination as well as rhinomanometry and rhinoresistometry. In the operating room, under local anesthesia, after performing intercartilaginous access and exposing the lateral surface of the triangular cartilage of the nose and the medial surface of the lateral pedicle of the cartilage of the alar nose, a stent of the alar nose was installed. The duration of the operation did not exceed 15 minutes, it was performed without bloodshed, and it did not require nasal tamponade. A positive effect in the form of improved nasal breathing was obtained on the operating table. The presence of a stent allowed the formation of an immature postoperative scar and reinforced the lateral wall of the nasal valve in the correct position. The presence of a stent did not negatively affect the appearance of the external nose. There were no complications. After 14 days, the stent was removed, a second cycle of studies of the respiratory function of the nose was carried out. Since it is minimally invasive, safe, cheap, and effective, the technique can be considered promising and requires further development.

The development of technologies in the modern practice of an otorhinolaryngologist and dentist creates the possibility of simultaneous surgical treatment of patients with chronic rhinosinusitis (CRS) and secondary adentia (SA) of the upper jaw using functional endoscopic sinus surgery (FESS) and sinus lifting methods. The aim of this study was to choose an algorithm for surgical intervention in patients with CRS and SA of the upper jaw—a simultaneous correction against a two-stage treatment. In the course of the study, the features of the course of the postoperative period in 96 patients were considered. Preoperative preparation was standard for all patients (otorhinolaryngological examination, CT scan of the paranasal sinuses, test results). To assess the impact of ENT pathology on the quality of life of patients both before and after surgery, the Sino-Nasal Outcomes Test-22 (SNOT-22) and Hospital Anxiety and Depression Scale (HADS) were used. The results of the work demonstrated the possibility of simultaneous treatment of patients with CRS and SA. The assessment performed on the SNOT-22 score showed that this approach does not have a negative impact on the quality of life of patients compared with a two-stage intervention; on the contrary, it has a lesser effect on the psychological state of the operated patients (HADS), increasing adherence to treatment.
