1. THE USE OF THE AUTOMATED DIGITAL ZENITH CAMERA SYSTEM IN ISTANBUL FOR THE DETERMINATION OF ASTROGEODETIC VERTICAL DEFLECTION
Abstract: The Digital Zenith Camera Systems (DZCSs) are dedicated astrogeodetic instruments used to obtain highly accurate astrogeodetic vertical deflection (VD) data. The first Turkish DZCS, the Astrogeodetic Camera System (ACSYS), was developed in Istanbul, Turkey in 2015. The ACSYS was capable of determining astrogeodetic VDs with an accuracy of ~0.3 arcs

2. Methods for the Control of Extreme Response Styles in Self-Report Instruments: A Review
Resumo Estilos de respostas são formas sistemáticas de responder a itens de autorrelato, que podem interferir na validade e precisão dos escores de instrumentos. Um tipo específico é o estilo de respostas extremas (RE), em que a pessoa tende a usar categorias extremas de resposta (por exemplo, concordo totalmente e discordo totalmente), em detrimento do

3. Analytical validation of real-time quantitative PCR assays for optimum diagnosis of vivax malaria
BACKGROUND The prompt diagnosis of plasmodial species for effective treatment prevents worsening of individual health and avoids transmission maintenance or even malaria reintroduction in areas where Plasmodium does not exist. Polymerase chain reaction (PCR) allows for the detection of parasites below the threshold of microscopic examination. OBJECTIVE O

4. Robot-assisted single port radical nephrectomy and cholecystectomy: description and technical aspects
ABSTRACT Introduction Robot-Assisted Single Site Radical Nephrectomy (RASS-RN) has been reported by surgeons in Europe and United States (1–3). To our best knowledge this video presents the first RASS-RN with concomitant cholecystectomy performed in Latin America. Case A 66 year-old renal transplant male due to chronic renal failure presented with an inc

5. TEMPORAL VARIABILITY IN ACTIVE REFLECTANCE SENSOR-MEASURED NDVI IN SOYBEAN AND WHEAT CROPS
ABSTRACT: Optimization of N management is one of the great challenges to be overcome in grain production, as it is directly related to productivity and can also cause environmental damage. Precision agriculture aims to solve this problem by applying nitrogen fertilizer at varying rates. Reflectance sensors are instruments capable of estimating N needs in var

6. Assessment of apically extruded debris and irrigant produced by different nickel-titanium instrument systems
The aim of this study was to evaluate the preparation time and the amounts of apically extruded debris and irrigant using different nickel-titanium instrumentation systems. Forty-five extracted single-rooted mandibular premolar teeth were selected and divided into three groups. The root canals were instrumented according to the manufacturers’ instructions,

8. AnÃlise do Fluxo de Gases na Camada de Cobertura do Aterro SanitÃrio Municipal Oeste de Caucaia (ASMOC) / Analysis of gas Flow in covering layer of Municipal Landfill West of Caucaia (ASMOC)
The growing human consumption entails a greater generation of waste, which, in turn, must be properly treated and disposed. The storage of waste in landfills produces gas, which if not managed properly will affect the quality of life. The uncontrolled emissions of these gases cause multiple economic, social and environmental impacts, as due to air pollution

9. A comparative evaluation of the efficacy of manual, magnetostrictive and piezoelectric ultrasonic instruments: an in vitro profilometric and SEM study
OBJECTIVES: The debridement of diseased root surface is usually performed by mechanical scaling and root planing using manual and power driven instruments. Many new designs in ultrasonic powered scaling tips have been developed. However, their effectiveness as compared to manual curettes has always been debatable. Thus, the objective of this in vitro study w

11. Behavior of granite-epoxy composite beams subjected to mechanical vibrations
The capacity to damp mechanical vibrations is one of the most important properties of granite-epoxy composites, even superior to the cast iron one. For this reason, these materials have been adopted for manufacturing of tool machine foundations and precision instruments. This work presents a study concerning the behavior of particulate composite beams, based
