The effect of the production of fly larvae in different substrates at different heights was evaluated. For this, a completely randomized bifactorial design was established with the following factors: Factor 1 – quantity of substrate (filter cake and hens manure, %), Factor 2 - height of the substrate in magenta (three and five, cm). A- 100 filter cake; B- 25% hens manure + 75% filter cake; C- 50% hens manure + 50% filter cake; D- 75% hens manure + 25% filter cake; E- 100% hens manure at three centimeters in height and E, F, G, H, I with the same proportions of substrates at five centimeters in

From the producers’ point of view, there is no universal and quick method to predict bruise area when dropping an apple from a certain height onto a certain type of substrate. In this study the authors presented a very simple method to estimate bruise volume based on drop height and substrate material. Three varieties of apples were selected for the study: Idared, Golden Delicious, and Jonagold. Their weight, turgor, moisture, and sugar content were measured to determine morphological differences. In the next step, fruit bruise volumes were determined after a free fall test from a height of 10

This paper proposes a new generation of antenna that applies Meta material properties at ground Plane. The paper analyzes the performance of Micro strip Patch Antenna with and without using the Meta material structure. Effect of bandwidth due to change of substrate height and dielectric constant have been investigated. Finally, bandwidth for each substrate height and dielectric constant is measured for selecting the optimal patch antenna.

Purpose Once an uneven substrate is aligned, traditional control theories and methods can be used on it, so aligning is of great significance for the development of wire and arc additive manufacturing (WAAM). This paper aims to propose a shape-driven control method for aligning a substrate with slopes to expand the application of WAAM. Design/methodology/approach A substrate with slopes must be aligned by depositing weld beads with slopes. First, considering the large height differences of slopes, multi-layer deposition is needed, and the number of layer of weld beads must be ascertained. Seco

Atomic force and scanning electron microscopy methods were used to study aluminum thin films grown on sitallic substrates. This study is the first to show that ultrasonic vibrations of the substrate during deposition stimulate the formation of islands on the film surface. However, the average height and lateral dimensions of the islands are not significantly affected by ultrasonic perturba-tions of the substrate.

Height regulation is crucial in poinsettia (Euphorbia pulcherrima) production for both aesthetics and postharvest handling. Controlled water deficit (WD) offers a potential alternative to plant growth retardants (PGRs) for poinsettia height regulation. We have previously shown that WD can be used to regulate poinsettia stem elongation. However, it is not clear how WD can be used to achieve different plant heights and how it affects aesthetic qualities such as bract size. Our objectives were to determine whether a range of plant heights can be achieved using controlled WD and to investigate pos

Sliding angle (SA) has been widely employed to describe the sliding behaviors of water droplets on substrates. However, it does not work on highly adhesive surfaces since droplets cannot slide along the substrate even at a 90° tilt. In this work, a novel strategy has been developed to characterize the sliding/pinning behaviors based on the collision between a tilted substrate and falling droplets released from a certain height. The critical tilted angle of substrate (i.e., secondary sliding angle, SSA) and the critical releasing height (i.e., Hc) of water droplets have been introduced and meas
