ESCOLA SEM PARTIDO: DO CONTROLE À ESPOLIAÇÃO
Authors: Castilho Denis 
Published: May 2019

A primeira proposta do Escola Sem Partido (ESP) foi elaborada em 2004. Dez anos depois, com a eclosão de mobilizações e movimentos conservadores pelo Brasil, ganhou repercussão e forte apoio de parlamentares e de partidos de direita. Alegando provável doutrinação esquerdista nas escolas, autoproclamando-se apartidário e polemizando temas relativos às diretrizes educacionais, o movimento ampliou suas frentes de ação, e projetos de lei do ESP foram apresentados na Câmara dos Deputados e em Assembleias Legislativas de vários estados do país. Uma análise desses projetos e das concepções defendidas por seus apoiadores, conforme evidenciamos neste texto, revela outras faces do movimento. Os interesses implícitos, a disputa partidária, o vínculo com tendências totalitárias que instigam o cerceamento do trabalho docente e a ligação com um projeto mais amplo que visa fazer da escola um grande negócio via espoliação, acende um alerta e suscita um amplo debate sobre os reais interesses do ESP e suas implicações à educação do país. Essa discussão é fundamental para a construção de um contraponto mais eficiente, baseado no esclarecimento, no protagonismo e na luta por uma escola mais autônoma e democrática.

Financial Distress Prediction Through Cash Flow Ratios Analysis
Authors: Kamaluddin Amrizah , Ishak Norhafizah , Mohammed Nor Farizal 
Published: May 2019

The purpose of this study to examine the relationship of cash flow ratios in predicting financial distress companies, with industrial and consumer product companies in Bursa Malaysia as the sample. The study on financial distress is critical as it can lead to bankruptcy, which may adversely affect the economy of the country. Therefore it is worth exploring any indicators that can identify the possibility of financial distress in the company. The tools enable to address the potential problems that can mitigate from distressed financial position. Most prior studies in Malaysia focus on traditional financial ratios, while this study exploits the strength of cash flow ratios. The liquidity ratio, solvency ratio, efficiency ratio and profitability ratio utilized in this study are derived from the statement of cash flows. The Altman Z-score is used to measure the level of the financial distress. The findings show mixed relationships between solvency ratio and financial distress and a negative significant relationship between profitability ratio and financial distress, whilst efficiency ratio has no relationship with the financial distress. These results suggest that cash flow ratios are reliable tools to predict financial distress for Malaysian context. The study is useful in giving insights to the stakeholders in their decision making.
Jurisdição constitucional e a efetivação do direito fundamental a saúde
Authors: Mozetic Vinicius Almada , Dos Santos Paulo Junior Trindade , Moller Gabriela Samrsla 
Published: May 2019

Tem como tema Jurisdição Constitucional e a Efetivação do Direito Fundamental à Saúde. Neste sentido aponta-se a construção e evolução da Jurisdição Constitucional desde seu aspecto histórico até sua legitimação democrática, a qual dá baliza para que venha a efetivar o Direito Fundamental à Saúde, pois tal direito fundamental emerge das transformações do Estado de Direito Liberal ao Social, e assim os Direitos Sociais na atualidade são levados ao Judiciário. Haja vista, com o modelo de Estado Democrático de Direito a Constituição veio a reconhecer textualmente diversos direitos, e neste contexto o acesso a justiça resta evidente a efetivação do Direito à Saúde pela via Judicial, a qual as Cortes Supremas detém as decisões mais relevantes quanto ao tema para que assim se realizem. Portanto, a Jurisdição Constitucional transcende as suas funções frente as demais, pois passa a ser um órgão de clamor democrático para sim ter-se a realização dos direitos fundamentais, assim como demonstra-se em vários casos relacionados ao direito à saúde.

Micro-photoluminescence mapping of surface plasmon-coupled emission from InGaN/GaN quantum wells

Published: May 2019

Abstract
Micro-photoluminescence (PL) mapping was investigated to elucidate the detailed mechanism of surface plasmon (SP)-enhanced emissions from InGaN/GaN quantum wells (QWs) with Ag or Al coating. The PL wavelengths were obviously red-shifted with Ag films, while the PL peak wavelengths were not changed with Al coating. The relationship between the PL peak intensity and the PL wavelength at each pixel showed a positive or negative correlation for the uncoated part of the InGaN/GaN QWs with blue or green emission, respectively. We found that these correlations disappeared in the Ag-coated regions. These results suggest that the energy transfer from the excitons to the SPs should be much faster than that in the exciton localization and charge screening processes of the piezoelectric field in QWs. These effects were not observed for the Al-coated regions because the mechanism of PL enhancement should be quite different as we have suggested previously.
Influence of trap level on an Al0.6Ga0.4N/Al0.5Ga0.5N metal—semiconductor—metal UV photodetector

Abstract
The irradiation intensity and temperature characteristics of each response speed sample are measured to clarify the high photosensitivity mechanism in an Al0.6Ga0.4N/Al0.5Ga0.5N metal–semiconductor–metal photodetector. A tradeoff relation could be observed between the photosensitivity and response speed when the dependence of the saturated photocurrent on the irradiation intensity was investigated by changing the irradiation intensity from 1 nW cm−2 to 45 μW cm−2. The rise time of the photocurrent after exposure to ultraviolet light was measured to determine the trap level density that was estimated to be ca. 1012 cm−2. Further, the decay time constant was obtained by investigating the dependence of the photocurrent decay time on temperature (25 °C–180 °C). By analyzing the Arrhenius plot of the decay time constant versus inverse temperature, trap level depths of 0.23 and 0.67 eV were obtained. Thus, the high photosensitivity in the Al0.6Ga0.4N/Al0.5Ga0.5N photodetector can be attributed to the carriers trapped in deep-level traps.

Published: May 2019

Abstract
The effect of internal strain on the luminescence properties of an InGaN single quantum well (SQW) was investigated as a function of modification via an underlayer (UL). Single In0.25Ga0.75N QWs (λ = 520 nm) 3 nm thick were grown on various ULs on a sapphire substrate, where the two UL types included (1) a buffer layer onto which an InGaN layer with a very small amount of In was inserted and (2) a buffer layer grown using different carrier gases. The SQWs were then analyzed by temperature-dependent time-resolved photoluminescence, scanning electron microscopy and cathodoluminescence. The experimental results show that the density of non-radiative recombination centers and the level of potential fluctuation in the SQWs decrease with insertion of an In

N UL possessing a quite low but sufficient indium content (x = 0.007). The density of non-radiative recombination centers in the SQW on the H2 carrier-grown UL, however, is large.

Abstract
GaN PolarMOS is a vertical power transistor incorporating the unique polarization-induced bulk doping scheme in III-nitrides for the body p-n junction. We report the realization of this device, wherein the vertical channel, source contact, and body contact regions are successfully formed using three steps of selective-area epitaxial regrowth, all by molecular beam epitaxy (MBE). The fabricated PolarMOS has an excellent on-current of >500 mA mm−1 and a specific on-resistance of 0.66 mΩ · cm2. The reverse breakdown mechanisms of the PolarMOS are investigated. First, a pronounced source-drain vertical leakage is identified and attributed to the passivation of the buried p-type body, which is subsequently resolved by the sidewall activation method. With the body leakage eliminated, the breakdown voltage is found to be limited by a highly conductive path along the regrowth sidewall interface using the conductive scanning probe technique, despite the absence of apparent structural defects.
Correlation between nanopipes formed from screw dislocations during homoepitaxial growth by metal-organic vapor-phase epitaxy and reverse leakage current in vertical p–n diodes on a free-standing GaN substrates

Published: May 2019

Abstract
We fabricated p−n diodes under different growth pressures on free-standing GaN substrates of the same quality and observed a noteworthy difference in the reverse leakage current. A large reverse leakage current was generated by nanopipes, which were formed from screw dislocations in the homoepitaxial layer. There were two types of screw dislocation observed in this study. The first type already existed in the substrate and the other was newly generated in the epilayer by the coalescence of edge and mixed dislocations. An increase in the growth pressure suppressed the transformation of screw dislocations into nanopipes, which led to a reduction in the reverse leakage current. To reduce the leakage current further, it is necessary to apply growth conditions that do not transform screw dislocation into nanopipes and to use a free-standing substrate without threading dislocations, that become nanopipes.

Aims: The aim of the study was to estimate the incidence of Community-acquired pneumonia (CAP) among patients with chronic obstructive pulmonary disease (COPD).
Study Design: A retrospective cohort study.
Place and Duration of Study: King Abdulaziz Medical City in Riyadh between January 2016 to March 2018.
Methodology: From the medical file, we identified patients with COPD diagnosis who admitted to the hospital. Then we identified the patient who develop CAP after the diagnosis date of the COPD. Other variables such as demographic factors, clinical outcome, comorbidity disease, length of stay in the hospital, and mortality were identified for each patient using their electronic medical file.
Results: Out of 363 COPD patients, 122 (33%) had developed CAP after the date of COPD diagnosis. Based on patient characteristics, the mean age of them was 75.39 years SD was 9.76 and 65% of the patients were female. The available evidence indicates that the mortality rate was n=22 (18.0%). Among those patient, 33 patients were admitted to ICU (27.0%) the rest of patients either wards n= 59 (48.4%) or both n=28 (23.0%). Among our study population, 97.4% had hypertension, 88.6% of the patients had diabetes, and 28.9% had renal failure. Majority of the study population have been placed on non-invasive ventilation n=94 (77.0%).
Conclusion: This study has been shown that COPD patients had increased risk of CAP. Patients who have multiple comorbidity diseases and got CAP with COPD have a higher risk of morbidities and mortality rate, especially elderly patients.Mention the design of the study here.

MODEL SUMBER DAN PENYEBAB REWORK PADA TAHAPAN PROYEK KONSTRUKSI
Authors: Chundawan Erick , Alifen Ratna Setyawardani 
Published: May 2019

Dalam dunia konstruksi, rework merupakan hal yang tidak dapat dihindari. Rework dapat terjadi akibat adanya kesalahan pengerjaan yang disebabkan oleh change, error ataupun omission. Beberapa penelitian menyatakan bahwa penambahan biaya yang diakibatkan karena terjadinya rework pada proyek konstruksi di Surabaya adalah sebesar 5.7% dari total biaya proyek.

Pada penelitian ini dilakukan penyebaran kuisioner kepada kontraktor di Surabaya. Kuisioner disusun berdasarkan pada tahapan konstruksi, sumber rework dan penyebab rework guna merancang sebuah model rework pada proyek konstruksi. Dengan dibuatnya model sumber dan penyebab rework para manajer proyek dapat mengantisipasi terjadinya rework sesuai dengan tahapan konstruksi.

Hasil penelitian menunjukkan bahwa pada proyek konstruksi, rework sering terjadi pada tahapan finishing. Sumber rework yang harus diperhatikan untuk tahapan pekerjaan finishing adalah adanya perubahan (change) dan diikuti dengan adanya kesalahan yang terjadi (error), akibat faktor kepemimpinan dan komunikasi. Salah satu indikator utama dari penyebab rework yang memiliki intensitas tertinggi adalah kurangnya pengawasan di lapangan dan rencana kerja.

In construction, rework is unavoidable. Rework usually occurs due to mistake from workmanship cause by change, error and omission. Additional cost accruing from of rework on a construction project in Surabaya is around 5.7% from the total cost of project.

In this research, questionnaires were distributed to contractors in Surabaya. Questionnaires were composed based on the construction phases, the sources and the causes of rework in order to design a model of rework on construction project. With the establishment of the sources and causes model of rework project managers can anticipate the occurrence of rework in accordance with the project construction phase.

The research findings show that construction project in general, rework happens frequently in the phase of finishing activity in the construction phase, the sources of rework that must be considered for finishing activity is due to change order and followed by error that is caused by lack of leadership and communication. The highest intensity of the main indicators of the causes is inadequatecy of supervision and job planning.
Achieving a High Fill Factor and Stability in Perylene Diimide–Based Polymer Solar Cells Using the Molecular Lock Effect between 4,4′‐Bipyridine and a Tri(8‐hydroxyquinoline)aluminum(III) Core

Published: May 2019

AbstractTwo novel perylene diimide (PDI)–based derivatives, Alq3‐PDI and Alq3‐PDI2, are synthesized by flanking a 3D tri(8‐hydroxyquinoline)aluminum(III) (Alq3) core with PDI and a helical PDI dimer (PDI2) to construct high‐performance small molecular nonfullerene acceptors (SMAs). The 3D Alq3 core significantly suppresses the molecular aggregation of the resulting SMAs, leading to a well‐mixed blend with a PTTEA donor polymer and weak phase separation. Compared with Alq3‐PDI, the extended π‐conjugation of Alq3‐PDI2 results in higher‐order molecular packing, which improves the absorption and phase separation behavior. Thus, the Alq3‐PDI2 devices have higher Jsc and FF values and better device performance, which are further enhanced by a small amount of 4,4′‐bipyridine (Bipy) as an additive. The coordination between Bipy and the Alq3 core promotes molecular packing and phase separation, which lower charge recombination and enhanced charge collection in the resulting devices. Therefore, a largely improved Jsc of 15.74 mA cm−2 and very high FF of 71.27% are obtained in the Alq3‐PDI2 devices, resulting in a power conversion efficiency of 9.54%, which is the best value reported for PDI‐based polymer solar cells. The coordination can also serve as a “molecular lock,” which prevents molecular motion and thus improves device stability.
