An Evolutionary-Based Prediction Model of the 28-Day Compressive Strength of High-Performance Concrete Containing Cementitious Materials
Authors: Sadrossadat Ehsan , Basarir Hakan 
Published: May 2019

Abstract
High-performance concrete (HPC) is a class of concretes that may contain more cementitious materials other than portland cement, such as fly ash and blast furnace slag, in addition to chemical admixtures, e.g., plasticizers. Strength, durability, and rheological properties of the normal concrete are enhanced in HPC. The compressive strength of HPC can be considered as a key factor to identify the level of its quality in concrete technology and the construction industry. This parameter can be directly acquired by experimental observations. However, testing methods are often time consuming, expensive, or inefficient. This article aims to develop and propose a new mathematical equation formulating the compressive strength of HPC specimens 28 days in age through a robust artificial intelligence algorithm known as linear genetic programming (LGP) using a valuable experimental database. The LGP-based model proposed here can be used for manual calculations and is able to estimate the compressive strength of HPC samples with a good degree of accuracy. The performance of the LGP model is confirmed through comparing the results with those provided by other models. The sensitivity analysis is also conducted, and it is concluded that the amount of cementitious materials, such as cement and furnace slag, have more influence than other variables.
Grid-Interconnected Solar Photovoltaic System for Power Quality Improvement Using Extended Reference Signal Generation Strategy
Authors: Suresh K. P. , Ramesh S. 
Published: May 2019

Abstract
This research article exhibits a utility grid-interfaced solar photovoltaic (SPV) system for power quality enhancement. An adaptive proportional integral derivate (APID) controller with a unit vector template (UVT) is employed to generate a reference current signal of a shunt active power filter (APF). The UVT-based control scheme is used to separate the fundamental components from the load currents and to estimate the reference phase currents. These currents are used to generate pulse width modulation signal for the shunt APF. To maintain a constant dc link voltage of shunt APF, an APID controller is employed in the dc link voltage regulator. This extended reference signal generation scheme of shunt APF remarkably enhances the system performance and also diminishes the current and voltage harmonics in the power distribution system. The presented reference current generation scheme has been mathematically examined, and digital simulation results under different steady and dynamic states are presented. The SPV system is accomplished by utilizing the incremental conductance maximum power point technique and is interconnected with the utility grid. Finally, the entire system is validated through the real-time hardware prototype developed by using dsPIC30F4011.

AbstractDopamine is hypothesized to convey error information in reinforcement learning tasks with explicit appetitive or aversive cues. However, during motor skill learning feedback signals arise from an animal’s evaluation of sensory feedback resulting from its own behavior, rather than any external reward or punishment. It has previously been shown that intact dopaminergic signaling from the ventral tegmental area/substantia nigra pars compacta (VTA/SNc) complex is necessary for vocal learning when songbirds modify their vocalizations to avoid hearing distorted auditory feedback (playbacks of white noise). However, it remains unclear whether dopaminergic signaling underlies vocal learning in response to more naturalistic errors (pitch-shifted feedback delivered via headphones). We used male Bengalese finches (Lonchura striatavar.domestica) to test the hypothesis that the necessity of dopamine signaling is shared between the two types of learning. We combined 6-hydroxydopamine (6-OHDA) lesions of dopaminergic terminals within Area X, a basal ganglia nucleus critical for song learning, with a headphones learning paradigm that shifted the pitch of auditory feedback and compared their learning to that of unlesioned controls. We found that 6-OHDA lesions affected song behavior in two ways. First, over a period of days lesioned birds systematically lowered their pitch regardless of the presence or absence of auditory errors. Second, 6-OHDA lesioned birds also displayed severe deficits in sensorimotor learning in response to pitch-shifted feedback. Our results suggest roles for dopamine in both motor production and auditory error processing, and a shared mechanism underlying vocal learning in response to both distorted and pitch-shifted auditory feedback.

Published: May 2019

The global financial crisis has hit the global business and society hard and has caused a mistrust in the monitoring and control of the banking sector a decade ago. The distrust encouraged supervisory authorities to reinforce the bankruptcy preventive measures, that are being developed to prevent or mitigate the negative effects of the new crisis. The development and permanent application of reliable bankruptcy prediction models are the part of such preventive measures. The aim of the study was to create a universal straightforward bankruptcy prediction model for the European banking sector, based on the analysis of financial ratios. The study examines the scholarly literature and deploys the theoretical methods of comparative analysis, critical evaluation, systematisation, generalisation. The empirical research involves expert assessment method, analysis of financial statements, data collection, structuring and modification, modelling: binary logistic regression, correlation, graphical representation of data, ROC curve. Research and results: based on selected 24 variables (ratios), five binary logistic regression models were created. The accuracy was tested on the ROC curve, together with the comparison of II type errors, which were made while predicting bank’s failure 1 year and 2 years before the distress. Main findings were: when models where validated and their II type errors were compared, the conclusion was made that model Z5 is the most suitable for predicting bankruptcy for the European banking sector. The accuracy to identify failing banks 1 year before the distress was 78.57%.

Published: May 2019

The type and severity of trauma injury; and the etiology of facial fractures is different according to the population studied. With the more stringent traffic laws, there was a reduction of facial fractures caused by automobiles accidents, but it still appears as the main cause and the prevalence of male and facial fractures. These fractures of the mandible condyle correspond 25-35% of mandible fractures diagnosed through radiographs projection Towne, panoramic and computed tomography. The same feature as the main etiological factors trauma by direct assault, car accidents, bicycle fall, fall from height and injury by firearms. Diagnosis of condylar fractures in pediatric patients should be very strict by the difficulty of obtaining information about the history of trauma, especially due to age of the patients affected. The etiology of condylar fractures in pediatric patients varies according to the stage of the child’s life (the 0-6 year of life and from the 6th year of life). The treatment of these fractures, especially in pediatric, when mishandled can cause permanent deformity. The treatment can be surgical or conservative, and should be made after the analysis of the age and gender of the patient, etiology and clinical conditions of fracture, time from the trauma, and dental occlusion. In pediatric patients, in most cases, the of first choice treatment is the conservative approach, because the ability of bone growth and bone remodeling that occurs.

Most toothpastes sold in Brazil contains abrasive composition with the function of preventing the formation of spots or pigmented film and burnish the tooth surface, however, the indiscriminate use of abrasives has generated discussion regarding the effects of this component. Objective: To evaluate dentifrices sold in the city of Salvador as to its commercial presentation, regarding the inormation contained in the packages related to abrasives, in order to verify if guidelines are offered to the public to assist them in choosing those products and to the professionals when it comes to the guiding elements of the prescription. Methodology: We have analyzed 45 packages of toothpaste, randomly purchased from supermarkets in Salvador, for two years. We have observed the following: component that guides the classification of toothpaste, type and concentration of abrasive and instructions with respect to the degree of abrasiveness. Results: All trademarks contained abrasive analyzed singly or in combination; eight types of abrasives have been found: Calcium Carbonate (27%), Silica (26%), Sodium Bicarbonate, Silicon Dioxide, Titanium Dioxide, trisodium phosphate, aluminum oxide and sodium silicate. Manufacturers have associated to the dentifrices naturals extracts with the purpose to prevent the dental color change without tooth and gengival aggression caused by abrasives associations. Conclusion: Lack of guidance on packaging about the level of abrasiveness of toothpaste that can guide patients and professionals to its rational use.

The significant development of biomaterials for use in clinical dentistry in the last decade has represented a powerful therapeutic tool in surgical activities, especially in the correction of bone defects. The guided tissue regeneration is a surgical practice in which it uses an artificial barrier called a biological membrane that serves as a barrier to epithelial migration to the success of new bone formation in areas of bone defects. Such membranes can be absorbable or not absorbable. This article discusses the use of the technique of guided bone regeneration techniques and the placement, composition, properties, advantages and disadvantages of the materials to be used.

Psychosomatic Associations Between Thinking Patterns and Parkinson's Disease from a Yoga Philosophy Perspective: A New Zealand Cross-Sectional Study
Authors: Maddela Sridhar , Buetow Stephen 
Published: May 2019

Abstract
When investigating the etiology of diseases, epidemiological observational studies traditionally deemphasize psychosomatic associations. Exploring cognitive behavior provides an insight into how psychosomatic associations affect disease. Yoga philosophy identifies the kleshas (mental afflictions) of ignorance, ego, desire, hatred, and fear of death with disease. This is because individuals' perceptions and beliefs generate and reflect streams of thought that may shape their behavior and manifest as, or predispose them to, particular disease(s). The present study takes a yogic philosophical perspective to help elucidate unexplored associations between thinking about different aspects of life and the severity of Parkinson's disease (PD). The study involved a cross-sectional sample survey. Parkinson's New Zealand selected a random sample of 990 of its members. A self-completed questionnaire was sent to them. It asked questions about how often, over the previous 4 weeks, they had thought about 18 aspects of life commonly associated with the kleshas. A completed questionnaire was returned by 319 people (32%). Respondents thought most about family (87%), health (64%), rest and sleep (57%), food (53%), and the future (52%). They reported thinking least about work (48%), sex (45%), death (42%), and being virtuous (39%). A weak, but hypothesized positive, association (r = 0.2, p &lt; 0.000) was detected between PD severity and thinking about death. The study could not determine whether thinking about death was (1) a cause or consequence of PD severity, and (2) a premorbid behavior. However, the possibility that stress associated with thinking about death accelerates PD progression is consistent with yoga philosophy and with neurophysiological mechanisms associated with the psychosomatic connections. The findings are worthy of future testing. A retrospective cohort study and qualitative research could deepen understanding about the role of kleshas in PD.

Published: May 2019

Background: To study the correlation of clinical features, spirometry, pulse oximetry assessment and haematocrit abnormalities in chronic obstructive pulmonary disease and to assess the severity of chronic obstructive pulmonary disease by spirometry.Methods: In the present study total 50 cases were selected on the basis of simple random sampling method from the Department of Pulmonary Medicine, Chalmeda Anand Rao Institute of Medical Sciences, Bommakal, Karimnagar, Telangana, India. During study period from June 2017 to December 2018.Results: About 50 patients of chronic obstructive pulmonary disease were studied. Majority of the patients were in the age group of 50-70 years. COPD was seen predominantly in male patients and majorities were smoker. In the majority of patients, the duration of illness was 6-10 years, cough with expectoration was present in all patients. As the number of cigarettes/day and duration increases the severity of the disease also increases in the studied population. In the study, about 40 % of cases were in stage III disease. Computerised spirometry was found to be most sensitive investigation in diagnosing and assessing the severity of the disease in all these cases. As the severity and duration of the disease increases, they are more prone to develop hypoxia and polycythaemia as a complication. In present study 8 patients had hypoxia, as assessed by pulse oximeter.Conclusions: Computerized spirometry is a very useful investigation in the management of chronic obstructive pulmonary disease. Pulse oximetry is a useful tool in diagnosing periods of oxygen desaturation. Pulse oximetry also useful in monitoring the oxygen therapy during management. Haematocrit analysis is a useful adjunct in assessing the severity of the disease. Polycythaemia, even though uncommon in chronic obstructive pulmonary disease patients is one of the rare but preventable complication with early cessation of smoking and with oxygen therapy.
