Global warming and climate change have emerged as pressing issues closely associated with human activity the manufacturing sector, significantly contributing to change. Additive (AM), or 3D printing (3DP), shows great promise an alternative method but raises concerns regarding plastic waste generation. To tackle this challenge, recycling polymer plastics exploring natural materials for 3DP offer sustainable solutions. However, a comprehensive understanding of both aspects currently needs be...

Bone tissue engineering (BTE) holds promise for treating bone defects, and 3D-printed porous scaffolds are pivotal regeneration. This study explores the impact of material extrusion 3D printing (ME3DP) process parameters (i.e., layer height temperature) on made polyetherimide (PEI) BTE. The intricate relationships shaping scaffold dimensional accuracy, residual stresses, warpage tendencies were unveiled using comprehensive numerical simulations. Our findings reveal that higher heights...

In this paper, biomass in goat manure form is pyrolyzed by a fixed-bed reactor. The influence of the temperature within range 300–600 °C to be detected solid, liquid and gas products. Different product yields emerge according pyrolysis temperature. At 500 °C, yield reaches maximum valuation, bio-oil obtained at analyzed via chromatography mass spectrometry (GC/MS) elemental analysis. highest efficiency reached 26.1% weight °C. As result TGA analysis, it was observed that separation rate...

Compression impact tests were determine the depends on direct damaging fruit. carried out by using a compression test device at 1 mm min−1 load velocity. Deformation, bioyield point force, deformation energy, Poisson's ratio determined data. Absorbed volume, tests. Impact pendulum with 50-cm arm length. These two directions nectarine, namely, from bottom side...

ABSTRACT The drying characteristics and changing of water activity ( A w ) values Kirmizi Siirt pistachio cultivars were determined experimentally as a function air temperature initial moisture content during hot drying. experiments conducted using two levels (32 38%) three temperatures (40, 50 60C) at 1.5 m/s velocity 12% relative humidity. curves obtained from the experimental data then fitted to 10 different semitheoretical and/or empirical thin‐layer models. ratios any time compared by...

ABSTRACT The mechanical properties of Nonpareil versus Gulcan 101‐23 almond cultivars that have different shell were loaded between two parallel plates to determine the rupture force, energy, power requirement, toughness and firmness. tests carried out with three moisture contents, namely, 7.2, 22.9 33.6% wet basis loading axes ( x , y z ). Physical characteristics such as length, width, thickness, geometric mean diameter, sphericity, volume, surface area weight determined. both increased a...

Technical information and data on the physical mechanical properties of agricultural animal products are necessary to design various equipments for agriculture industry. In this study some such as mass, length, diameter, geometric mean surface area, sphericity, volume, coefficient friction packaging were determined Japanese quail eggs. Furthermore, behaviour eggs was in terms average rupture force, deformation toughness (energy absorbed by per unit volume). Egg samples compressed along their...

This study examined the methods adopted in Turkey to remove cotton stalks remaining field after harvest and quantified efficiency of different mechanized stalk choppers. In this study, performance three types choppers was assessed (chain-type, splined-type vertical-blade rotating dredge). Field experiments were conducted with each type determine proportion non-uprooted stalks; mean “post-chopping height” stalks, measured from soil surface; frequency distribution piece length scattered around...

ABSTRACT The objective of this study was to investigate the effects heating process and striking on splitting breaking pistachio nuts obtaining their kernels without damage. For purpose, (350C) applied nuts. Heated were dropped onto rotating disk then thrown strike wall container by centrifuge effect . Striking velocity adjusted with a that driven an electrical engine. Three different rotations (400, 500 600/min) three moisture contents pistachios (6.5, 22.0 42.5%) evaluated in experiments....

Trunk shakers are widely used in the harvesting of tree fruits. The vibration produced by trunk is obtained rotating eccentric masses. In shakers, a single mass as well double mass. However, there no study on their effectiveness relative to each other if these masses and double. this study, effect compared when they operated axial or parallel positions instead For purpose, shaker was designed for stiff manufactured after modeling 3D. 3D model simulated ANSYS software. Afterward, experiments...
