The composer Chiquinha Gonzaga: breaking paradigms and “opening wings”

This qualitative investigation and bibliographical basis have as its central objective to present a nucleus of reflections on the historical/social, professional and musical process of the composer, conductor and pianist Francisca Edwiges Neves Gonzaga (1847-1935), better known as Chiquinha Gonzaga, presenting important achievements for the female universe, a struggle that is still necessary in contemporary times. Their actions, breaking countless paradigms of current society, address considerations that deserve attention such as: machismo; social imbalance regarding women’s rights; professional prejudice base on unfounded foundations; inequality in the political and economic field; prejudices in the process of musical creation; ethnic-racial position, increasing the unacceptable condition of not having the right to freedom and autonomy, essential items for the construction of a fair and humane society. The reflective content about the aforementioned composer is in continuous dialogue with the present, confirming that revisiting the past helps in the evaluation and critical position of the present day.

Technical evaluation of steel roof trusses for a large pool basin

In this work, we carry out a technical evaluation of steel roof trusses for a large basin of the Del’fin pool in the city of Ust-Ilimsk with the purpose of determining their further operability. This task involves establishing the damage degree of building structures and the category of their technical condition based on a comparison between the actual values of quantifiable attributes and those established by the project or regulatory documents. The studied objects are represented by steel trusses with a span of 15 m, located in plan with a spacing of 6.0 m and conditionally divided into 2 groups: reinforcement trusses (F-1 and F-4) and existing trusses without reinforcement (F-2 and F-3). We analyze the technical, as-built, and operational documentation, and carry out visual and measuring control procedures. The verification calculation of the most loaded truss elements is presented (not provided in the article). According to the analysis of the obtained data, the condition of the studied steel trusses can be concluded as unacceptable and emergency. The emergency technical condition of the F-2 and F-3 trusses is due to the unprovided bearing capacity of support brace struts and insufficient length of welds, fastening the support brace struts. The unacceptable technical condition of the reinforcement trusses F-1 and F-4 is due to the insufficient length of the welds, fastening the support brace struts, as well as the deviations in a number of technical solutions, outlined in the reinforcement project, from the current norms. Recommendations on the further operability of roof structures are provided.

Some results of the technical survey and approaches to strengthening of the monolithic reinforced concrete structures of the sports complex “Climbing Center”

The construction of sports facilities using cast-in-place reinforced concrete has recently acquired a steady trend towards its development. This was largely facilitated by the development of the regulatory framework for design, as well as modern construction technologies. At the same time, the practice of implementing monolithic structures shows that there is often a low-quality production of construction works. The main defects and deviations made in reinforced concrete structures are shown on the example of the Climbing Center building under construction.One of the main defects was the recorded damage to the corbels of the main pylons of the structure, on which the large-span trusses rest. The survey showed that the result was an unacceptable technical condition of these elements. In order to bring the structures to the standard level of technical condition, a design for strengthening the support nodes of the trusses was developed and implemented, which is presented in the text of the article.

Acoustic emission and moving window-improved kernel entropy component analysis for structural condition monitoring of hoisting machinery under various working conditions

Acoustic emission (AE) has been widely used to the nondestructive evaluation (NDE) and structural health monitoring (SHM) of hoisting machinery recently. Kernel entropy component analysis (KECA) is generally applied to extract the AE features based on its excellent nonlinear ability. However, traditional KECA specifically requires a considerable number of components (e.g. eigenvalues and eigenvectors) to excellently describe the original data, which leads to a reduction in the effect of approximate dimensionality reduction of high-dimensional data, thus causing readily unacceptable condition monitoring result. To overcome this weakness, a novel method named moving window-improved kernel entropy component analysis (MW-IKECA) is proposed in this study for structural condition monitoring of hoisting machinery, which is aimed at extracting more AE feature information and improving the condition identification accuracy. Firstly, a twiddle factor is introduced in the KECA model for the purpose of breaking the restriction that the projection axes originate only from the feature vectors and maximizing the independence between the components. Meanwhile, the moving window local strategy is incorporated into the proposed IKECA to extract more rich and effectiveness AE feature information at different scales. Finally, the Cauchy–Schwarz (CS) statistic is utilized to calculate the similarity between probability density functions and maintain the angular structure of the MW-IKECA feature space for the task of improving the monitoring accuracy and shortening the monitoring time-delay of MW-IKECA. Results of the experimental and practical engineering application validate the effectiveness and superiority of the proposed method in AE-based crane SHM under different working conditions compared with the traditional KECA and some combinatorial methods.

Risk Analysis Using Failure Modes, Effects, and Criticality Analysis for Transmission Network Assets

In this paper, we apply the Failure Modes, Effects, and Criticality Analysis (FMECA) approach to the criticality and risk analysis of the efficiency, safety/reliability, environment, and financial criteria of the high voltage transmission line. In the efficiency analysis, the weighting-scoring method and analytical hierarchy process are applied to obtain the line renovation index, which is interpreted as efficiency severity. The safety/reliability severity relates to the system impacts are caused by failure of the equipment and the system. The environmental severity takes social impacts and pollution into consideration. The financial severity involves the cost of spare parts and maintenance costs, which are interpreted as the financial severity of the lines. Twenty practical transmission lines in Thailand with actual data for 115, 230, and 500 kV were studied. The transmission line components are divided into eight components including the conductor, conductor accessories, insulator, steel structure, foundation, lightning protection system, tower accessories, and right-of-way. The severity and criticality of the components and transmission lines are analyzed and plotted in criticality matrices based on four criteria. This criticality matrix is presented at four different levels including very low, low, medium, and high risk, as represented by four color bands: green, yellow, orange, and red, respectively. The results show that three 115 kV lines are the first priority for short-term reconstruction planning because of their unacceptable condition and high risk in terms of safety/reliability and financing. Recommendations for maintenance strategy and risk mitigation are proposed for the utility according to the utility’s actual criticality. Ultimately, maintenance planning of the transmission system can be effectively managed with higher reliability, a lower risk of failure, and a lower cost of maintenance.

Fire risk assessment on Floating Storage Regasification Unit (FSRU)

Floating Storage Regasification Unit (FSRU) is a variety of facilities that support Liquefied Natural Gas (LNG) supply chain activity. There are several potential fire hazards which could be harming human and cause death by the FSRU. This paper will discuss a fire risk assessment on the FSRU loading arms and gas export metering system. To begin, fire risk assessment is carrying out in several stages. The first step is to identify hazards using Hazard and Operability. Then, frequency analysis out of hazards events are complying by the Fault Tree Analysis and the Event Tree Analysis, these methods are to determine the type of potential hazards and to estimate frequencies of events. Henceforth, consequences analysis will be performing by fire modeling software. Finally, the result of the fire risk assessment can be carried out using risk mapping using standard f-N curve UK Offshore, if the risk mapping illustrates unacceptable condition, it is necessary to carry out a mitigation action using the Layers of Protection Analysis. Fire risk assessment indicates that the potential fire hazards which occur are jet fire, flash fire, and gas dispersion. Each hazard has leakage scenarios which are, small-bore (10-50 mm), medium bore (50-150 mm), and full bore (>150 mm). Thereupon, the result of consequence analysis indicates a various form of fire and expose areas which have an impact on marine crews. Based on the risk mapping, the results show that the fire risk assessment which has been carried out is in acceptable conditions and as low as reasonably practicable.

Association Between “Unacceptable Condition” Expressed in Palliative Care Consultation Before Left Ventricular Assist Device Implantation and Care Received at the End of Life

ContextPalliative care consultation before left ventricular assist device (LVAD) surgery (PreVAD) has been recommended, but its impact on goal-concordant care is unknown. ObjectivesTo describe the association between patients' unique unacceptable condition articulated during PreVAD with the actual care provided at the end of life. MethodsAmong 308 patients who had PreVAD between 2014 and 2019, 72 patients died before December 31, 2019. Based on the answers to the question, “Is there any condition you would find unacceptable?” patients were divided into ARTICULATE (those who could articulate their unacceptable condition clearly, n = 58) and non-ARTICULATE (those who could not, n = 14). Circumstances at death and end-of-life care were compared between groups. ResultsMean age at death was 63.2 years (SD ±13.1), 56 patients (77.8%) were males, and median duration of LVAD was 167.5 days (interquartile range 682). ARTICULATE patients died less frequently in the intensive care unit than non-ARTICULATE patients (33 patients, 57.9% vs. 13 patients, 92.9%; P = 0.014) and had ethics consultation less frequently (four patients, 6.9% vs. five patients, 35.7%; P = 0.011). Frequency of LVAD withdrawal was similar in both groups. Among ARTICULATE cohort, the unacceptable condition articulated in PreVAD did not seem to influence decisions at the end of life. ConclusionPatients who articulated their unacceptable condition clearly before LVAD surgery had less frequent ethics consultations and received less intensive care at the end of life, but it did not seem to affect the decision of LVAD withdrawal. It may be more important to engage in discussions around their unacceptable conditions, rather than the specific condition articulated. The question of an unacceptable condition should be part of any routine palliative care consultation before LVAD surgery.

Instrument implementation of an automated complex for recording physiological parameters of drivers

Goal of research: creation of an automated complex for quick and effective identification of an unacceptable condition of drivers before going to run and predicting their physiological state during a work shift. To achieve this goal in the creation of devices for the automated complex the following methods were used: photoplethysmographic method, pulse oximetric method, thermometric method. In the course of the research, results were achieved that make it possible to record physiological parameters of drivers with high reliability. This is achieved thanks to the use of the “isobestic point” photoplethysmogram in the registration at a length of 805 nm, the use of a two-channel pulse oximeter at wavelengths of 660 nm and 910 nm.

Activation of management role at promoting safety culture by increasing their commitment to safety culture. Recreational and financial incentives which have unique effect on the employee working at ICUs of Gaza city.

Exercise-Based Approaches to the Treatment of Cellulite

The presence of cellulite in women, as an unacceptable cosmetic condition related to skin and subcutaneous tissue, is a growing issue worldwide. Having a sedentary lifestyle is one of the most important factors regarding the formation of cellulite. However, only a limited number of scientific studies have been done to investigate the possible effects of exercise training on cellulite improvement. This focused review aimed to summarize the available evidence on this subject and provide a road map for conducting future exercise-based research on how to treat cellulite.

A PRELIMINARY STUDY ON THE EXTRAVASATION OF INTRAVENOUS CHEMOTHERAPY IN SANGLAH GENERAL HOSPITAL, BALI – INDONESIA

Background: Extravasation of intravenous chemotherapeutic agents is one of the most devastating complications, which unacceptable condition neither to patient nor to medical services. Many healthcare providers realize that even one extravasation injury is too many since this injury is preventable. Published incidence rates of chemotherapy extravasation range from 0,01% to 6%, but in our institution, chemotherapy extravasation was not well recorded, so the incidence rate is unclear and the number of injuries is underestimated. Method: We observed chemotherapy extravasation occurrence during a 6 months period in our institution, from September 2013 until March 2014. We recorded the chemotherapy agents, patient’s clinical presentations, and extravasation management.Result: During our observation, 1374 chemotherapies administered, and 10 cases of chemotherapy extravasation occur, particularly doxorubicine was the main chemotherapy agent. Almost all treated conservatively, only 10% handled with surgical management. Eventually, 20% of cases have implanted port placed.Conclusion: Extravasation of cytotoxic agents is a serious problem, it causes tissue damage, prolongs the length of stay, increases hospital cost and psychological damage to cancer patients who under chemotherapy. It preventable but always underestimate by some clinicians, the use of central venous access device is one of the solutions to minimize the damage.

A második USA–Észak-Korea csúcstalálkozó

The second summit between the United States and North Korea was held on February 27, 2019. The negotiations in Hanoi between Donald Trump and Kim Jong-un began in an optimistic atmosphere, but it was abruptly cut short the next day. The first information about the reasons became public at a press conference. According to these, there were insurmountable differences between the standpoints of the parties. Although North Korea offered serious concessions which contained the dismantlement of the Yongbyon nuclear facilities, Trump could not accept less, than total denuclearisation. From the perspective of the North Korean Government, that was an unacceptable condition. When this became clear, the American delegation stood up from the negotiating table without signing the final agreement. This article aims to present the antecedents and potential consequences of the failed summit.

Litter impacts on beach/dune systems along the Atlantico Department, the Caribbean Coastline of Colombia

Eight beach/dune systems located along the Atlantico Department, Caribbean coast of Colombia were surveyed to determine litter influences over its scenic quality. Application of the Coastal Scenic Evaluation System (CSES) categorized these systems into two of the five available classes. Five of the investigated beach/dune systems belong to Class IV, while three systems correspond to V. Classes I, II and III were not found. Along these beach/dune systems, a total amount of 1908 litter items were collected with average abundances of 4.2 items/m2. Currently, 82% of surveyed sites are under an unacceptable condition of cleanness. User's habits as well as bad litter management practices are directly responsible for the decline of scenic quality of the Atlantico Department beach/dune systems. Litter management must be centered on strategies to eliminate or minimize litter sources. Specific remedial actions need to be defined and developed.

Abundance and distribution of beach litter along the Atlantico Department, Caribbean coast of Colombia

A total of 5993 litter items divided into 13 categories were found at 25 beaches located along the Atlantico Department coastline, Caribbean of Colombia, with an average litter abundance of 7 items/m. Agglomerative Hierarchical Clustering (AHC), Multidimensional Scaling (MDS) and Principal Components Analysis (PCA) were applied with the objective of highlighting similarities and contrasts between litter categories and abundances. Results indicated two specific groups of beaches in terms of amounts of litter. The first group is composed of 17 “dirty beaches” (urban, resort and village) while the second group includes 8 “clean beaches” (village and resort). This division was confirmed by means of the EA/NALG (2000) grading system, which highlighted that 68% of beaches belonging to the Atlantico Department coastline are in an unacceptable condition of cleanness. Current patterns of litter abundance and accumulation are related to sources as well as beach characteristics such as degree of exposition and morphodynamic state.

Physiological response of building occupants based on their activity and the indoor environmental quality condition changes

This study aimed to analyze the physiological response (i.e., blood pressure) of building occupants based on the 22 subjects' activity and the Indoor environmental quality (IEQ) condition (i.e., carbon dioxide (CO2) concentration and operative temperature) changes. The experiment was designed with three scenarios to simulate the IEQ condition changes. In each scenario, six cognitive tasks that simulate office work were conducted by the subjects to determine their activity that cause work stress. The paired-t test was conducted to analyze the building occupants' physiological response by scenario. As a result, with a low CO2 concentration (below 1000 ppm), the subjects maintained homeostasis well under work stress. It was difficult to maintain homeostasis, however, with a high CO2 concentration (above 2000 ppm): When the subjects were under work stress, they showed different responses compared to those of the seated state. Homeostasis was affected by stress, according to the IEQ condition changes. The unacceptable condition and work stress were particularly dangerous for the hypertensive (i.e., above 140 mmHg systolic blood pressure) subjects. For the maintenance of homeostasis of occupants, a low CO2 concentration (below 1000 ppm) should be kept, and work stress above a certain level should be avoided. The building's mechanical system designer and facility manager can manage the IEQ condition considering the building occupants' physiological responses, which can be used as an IEQ condition management guideline for health.

Preventing Suture Extrusion and Recurrence in Mustarde and Furnas Otoplasties by Using Laterally Based Postauricular Dermal Flap, Long-Term Results.

Prominent ear deformity (PD) is an unacceptable condition of pinna that affects 5% of the population and is associated with emotional stress, behavioral disturbances, and social restrictions in relationships. Conchal hypertrphy, inadequate formation of antihelical fold, earlobe placement ahead than it should be, or various combinations of these changes are main characteristics of PD. Many surgical techniques have been described for the PD.The authors' aim was to present laterally based postauricular dermal flap combination with cartilage-sparing methods and effectiveness of this technique in suture extrusion prevention and reducing the rate of recurrence with long-term results. Forty-one patients had bilateral and 6 patients had unilateral PD, a total of 47 patients with a mean age of 14.48 were operated by using this combined procedure. A laterally based supraperichondrial dermal flap was prepared from a deepithelized elliptical postauricular incision. Mustarde and Furnas suture techniques were used solely for PD correction. The dissected laterally based dermal flap was fixed to the mastoid bone with sutures in stretched position after reshaping the auricular cartilage with sutures. The average helix-mastoid distance was (mm) 16.28 ± 2.36, concha-mastoid angle was 25.71 ± 0.96° on 12-month measurements. The helix-mastoid distance showed an increase of 1 to 3 mm, in the concha-mastoid angle measurements of 1° to 2°. Statistically significant changes were observed between the average preoperative, postoperative 1. month, postoperative 12. month helix-mastoid distances (mm), and month concha-mastoid angle (°) measurements (P = 0.0001). The laterally based postauricular dermal flap technique is an effective method to prevent suture extrusion and recurrence which are the most important complications of otoplasty procedure and easy to apply.

CLINICAL EVALUATION OF SELF-ADHERING FLOWABLE COMPOSITE IN NON-CARIOUS CERVICAL LESIONS

Introduction: The clinical management of non-carious cervical lesions is a challenge concerning restoring procedures because the lesions have non-retentive cavity shape and margins lying on dentin or cementum which are unfavorable for bonding. Objective: To evaluate the clinical performance of two self-adhering flowable composites compared with flowable composite and resin modified glass ionomer in restoration of non-carious cervical lesions for 1 year. Materials and Method: A total of 60 non-carious cervical lesions (15 for each material) were restored with self-adhering resin flowable composites (VertiseTM Flow and FusioTM Liquid Dentin), flowable composite with ExciTE F dental adhesive system and resin modified glass ionomer. The outer surface of the dentinal wall was roughened with a water-cooled high-speed diamond bur. Occlusal or incisal enamel margins were beveled, and no mechanical retention was performed. The restorations were re-evaluated with the modified United States Public Health Services (USPHS) criteria at baseline, 3, 6 and 12 months. Results: After 1 year, 14 of the 15 Vertise Flow and 12 of the 15 Fusio Liquid Dentin restorations were in a clinically unacceptable condition due to retention failure. The success rates of Vertise Flow (6.7%) and Fusio Liquid Dentin (20%) were less when compared to the success rate (80%) for the 2-step etch and rinse/Flowable composite and (60%) for the resin modified glass ionomer restorations (P-value < 0.001) Conclusion: The clinical performance of the self-adhering resin flowable composites showed higher failure rate than other restorative materials after 1 year of clinical use.

Analysis of SBO ATWS for Maanshan PWR

AbstractStation blackout anticipated transient without scram (SBO ATWS) is considered as loss of off-site and on-site power but no credit for automatic reactor trip. SBO ATWS causes reactor coolant pump (RCP) trip, loss of all main feedwater pumps and turbine trip, then the reactor coolant system (RCS) pressure rises rapidly due to loss of heat removal paths. The ASME Code Level C service limit criteria of 22.06 MPa (3200 psig) is assumed to be an unacceptable plant condition in SECY-83-293. The simulation is performed by TRACE which is a thermal-hydraulic code developed by U.S. NRC. Three different AFW flows are modeled to ensure the pressures will not be beyond the criteria. RCP seal-leakage is concerned as a SBLOCA due to loss of RCP seal-cooling. Four possible leakage flows are modeled to examine the reactor core water level and temperature variation.

The Palermo Protocol: Trafficking Takes it All

The Palermo Protocol is the outcome of bargain and lobbying with global institutions, NGOs and government representatives embattling to enforce their interests. The outcome is the concept of trafficking that embraces the struggles against prostitution, slavery and child labour. This broad concept has allowed various local cultural practices and survival strategies of those who live under difficult conditions to become classified as trafficking. While such definition may facilitate fundraising there are adverse consequences to be considered. Firstly, hazardous conditions of children that obviously are not trafficking tend to become ignored. Second, the victims of “real” trafficking become invisible by the excessive number of children allegedly trafficked. Third, the broad definition of trafficking has contributed to criminalization of whole communities and consequent conflicts between NGOs engaged in anti-trafficking activities and the communities involved. Such a situation is not in the best interest of the children involved. Rather than spending huge amount of resources on the conventional anti-trafficking measures there is a need to address the root causes of whatsoever unacceptable condition a child is suffering from.

A Meshless Method for Helmholtz Equation Based on RBF and TSVD

In this paper, an improved meshless method for numerical solution of Helmholtz equation is presented. To overcome the unacceptable huge matrix condition number, we combine some Tikhonov regularization tools with radial basis function to solve the equations. Compared to the finite element method, a better result in numerical experiments will be approached using the proposed method. Furthermore, higher accuracy can be obtained by adopting suitable radial basis functions which is impossible for traditional RBF meshless method.
