Non-destructive leaf area measurement in maize (Zea mays L.).
In this research, leaf area prediction model was developed for some leaf-used maize (Zea mays L.) cultivars namely Coluna, Luce, Maveric, Ranchero, TTM-813, Zamora and RX-788 grown in Black Sea region of Turkey. Lamina width, length and leaf area were measured without destroying the leaf to develop the models. The actual leaf areas of the plants were measured by PLACOM Digital Planimeter and mu...
متن کاملMeasurement of pharyngeal cross-sectional area by finite element analysis.
A noninvasive measurement of pharyngeal cross-sectional area (CSA) during sleep would be advantageous for research studies. We hypothesized that CSA could be calculated from the measured pharyngeal pressure and flow by finite element analysis (FEA). The retropalatal airway was visualized by using a fiber-optic scope to obtain the measured CSA (mCSA). Flow was measured with a pneumotachometer, a...
متن کاملLeaf area estimation by a simple and non-destructive method
In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...
متن کاملAccuracy of replication for non-destructive surface finish measurement
Surface replication has been widely used in aerospace, automotive and other industries as a non-destructive method for examination and assessment of either surfaces difficult to be accessed by measurement tools or parts difficult to be dismantled for measurement. The fidelity and accuracy of the replication is one of the major concerns in actual applications. This paper presents a comprehensive...
متن کاملUltrasound does not provide reliable results for the measurement of the patellar tendon cross sectional area.
PURPOSE This study examined the reliability of patellar tendon cross sectional area (CSA) measurement using brightness mode ultrasonography. METHODS The patellar tendon CSA of fourteen participants was examined on two different days and at three different positions (proximal, median and distal). Five trials per day were conducted in each position, replacing the ultrasound probe on every trial...
