Direct ink writing (DIW) requires careful selection of composition with specific rheological properties, and it has limitations, such as the inability to create overhanging parts or branched geometries. This study presents an investigation into enhancing 3D printing process through use a heterophase system, aiming overcome these limitations. A modification was carried out in printer constructio...

Lightweight alloys produced by pressurized castings suffer from flow-induced microstructural segregation due to the migration of externally solidified crystals (ESCs). Although some qualitative research has been carried out on ESCs migration, quantitative prediction it is still demanded. In this respect, an model based hydrodynamics and rheological behaviour semi-solid metals (SSMs) proposed es...

Effect of High-Pressure with Temperature (HPP+T) and Thermal Processing (TP) were evaluated on the rheological characteristics mango pulp. Samples subjected to an equivalent condition a 5D (5 log reduction) process for HPP+T (600 MPa/6.3 min at 90 °C) TP (95 °C/10.5 min) be compared. Storage-modulus (G') loss-modulus (G'') modeled according oscillatory frequency using Power-Law. showed G' > ...

in this work, the characteristics of flow and heat transfer of a fluid containing nano particles of aluminum oxide with the water volume fraction (0.1-0.2-0.3)(v/v) percent of the reports. the overall heat transfer coefficient, heat transfer and the average heat transfer fluid containing nano water - aluminum oxide in a horizontal double pipe counter flow heat exchanger under turbulent flow con...

Abstract In the present study, alginate yield and composition were investigated during seasonal life cycle of alien brown alga Sargassum muticum harvested from Atlantic coast Morocco. Alginate ranged 11.14% in winter to 25.62% spring/early summer, coinciding with maximum vegetative growth. Monthly monitoring block structure showed that highest mannuronate (M)/guluronate (G) ratio was recorded d...

Fat has an important role in creating texture, color and viscosity; but, it might be a source of many diseases in human. Mayonnaise is one of the most widely used sauces that contains fat in its formulation. There is an increase demand in reduction of the amount of fat in the diet or use of unsaturated fat. In the present study, mayonnaise samples containing various amounts of sesame oil were p...

Microwave assisted extraction technique was employed to extract pectin from citron peel. Box-Behnken design was applied to investigate the influence of irradiation time, microwave power and pH on the yield and DE of pectin. The finding indicated that the optimal conditions for the maximum yield of pectin (30.71%) were achieved at irradiation time of 3 min, microwave power of 700 W and pH of 1.5...

The aim of this study was to produce the ice cream with potential antidiabetic effects by addition of pistachio peel extract (PPE) (0, 10, 20 and 30% on dry matter basis). The properties of produced ice creams such as physicochemical, rheological, antioxidant, antidiabetic and sensory properties were evaluated. The results indicated that ice creams containing 20 and 30% of PPE provided desired ...

in this paper, nonlinear vibration and instability response of an embedded pipe conveying viscose fluid is investigated. the pipe is considered as a timoshenko beam embedded on an elastic foundation which is simulated by spring constant of the winkler-model and the shear constant of the pasternak-model. the external flow force, acting on the beam in the direction of the flexural displacement is...
