1. MONITORING TRACTOR PERFORMANCE USING SHEWHART AND EXPONENTIALLY WEIGHTED MOVING AVERAGE CHARTS
ABSTRACT Statistical process control has been widely used in agricultural operations for monitoring and improving process quality. This study aims to evaluate the Shewhart and exponentially weighted moving average (EWMA) control charts to monitor the performance of an agricultural tractor–planter set. The design is completely randomized based on the assump

2. Thermal Dissipation Effect on Temperature-controlled Friction Stir Welding
Resumo Durante a Soldagem por Fricção linear (FSW) de geometrias complexas, a dissipação térmica, induzida por características geométricas ou pelo ambiente circundante, desempenha um papel importante na qualidade final da junta. Para garantir uma qualidade consistente em condições diferentes é necessário a adaptacão de parâmetros durante o proce

3. Torsional fatigue strength of reciprocating and rotary pathfinding instruments manufactured from different NiTi alloys
Abstract To evaluate the torsional properties of engine-driven pathfinding instruments manufactured from different NiTi alloys – R-Pilot (tip size 12.5;.04 taper; M-Wire) and One G (tip size 14;.03 taper; Conventional NiTi). A total of 40 NiTi instruments from engine-driven pathfinding instruments (n = 20) were used. The torsion tests followed ISO 3630-1 (

5. CROP DATA RETRIEVAL USING EARTH OBSERVATION DATA TO SUPPORT AGRICULTURAL WATER MANAGEMENT
ABSTRACT Accurate crop data are essential for reliable irrigation water requirements (IWR) calculations, which can be acquired during the crop growth season for a given region using earth observation (EO) satellite time series. In addition, a relationship between crop coefficients and the NDVI can be established to allow for crop evapotranspiration estimatio

7. The amount of spermatic cord rotation magnifies the time-related orchidectomy risk in Intravaginal testicular torsion
Abstract Purpose To investigate the roles of age, testicular rotation and time in the surgical outcome of intravaginal testicular torsion (iTT). Patients and Methods We retrieved the records of all iTT patients treated in our unit from January 2012 to January 2014. Explanatory variables were: age (years); presentation delay (PrD, time between symptoms and

8. INTERFACIAL ENERGY DURING THE EMULSIFICATION OF WATER-IN-HEAVY CRUDE OIL EMULSIONS
Abstract The aim of this study was to investigate the interfacial energy involved in the production of water-in-oil (W/O) emulsions composed of water and a Brazilian heavy crude oil. For such purpose an experimental set-up was developed to measure the different energy terms involved in the emulsification process. W/O emulsions containing different water volu

9. Occurrence and morphometrics of the brachioradialis muscle in wild carnivorans (Carnivora: Caniformia, Feliformia)
The brachioradialis is an important muscle that acts in the external rotation of the forearm (supination). However, its occurrence is controversial and little studied in the order Carnivora. Thus, this study investigates the occurrence and anatomo-functional arrangement of this muscle in wild carnivorans species. Fifty-eight thoracic limbs of specimens from

10. Validation of micro-computed tomography for occlusal caries detection: an in vitro study
Conventional methods of caries detection, including the gold standard of histological examination, have certain disadvantages that must be addressed prior to validating any other diagnostic technique—current or new. Here we evaluated the validity of micro-computed tomography (micro-CT) as an alternative gold-standard technique for caries detection. Sixty t

11. Performance assessment of the single photon emission microscope: high spatial resolution SPECT imaging of small animal organs
The single photon emission microscope (SPEM) is an instrument developed to obtain high spatial resolution single photon emission computed tomography (SPECT) images of small structures inside the mouse brain. SPEM consists of two independent imaging devices, which combine a multipinhole collimator, a high-resolution, thallium-doped cesium iodide [CsI(Tl)] col

12. Dinâmica de homeomorfismos homotópicos à Dehn twists / On the dynamics of homeomorphisms of the torus homotopic to Dehn twists.
No presente trabalho apresentamos um estudo sobre a dinâmica de homeomorfismos do toro homotópicos à Dehn twists. No caso conservativo, provamos que se $f$ preserva área e tem um levantamento $\\hat$ para o cilindro com fluxo zero, então, precisamente, ou $f$ é um homeomorfismo do anel, ou possui pontos no cilindro com velocidades verticais positiva e
