Common Wheat Pasta Enriched with Ultrafine Ground Oat Husk: Physicochemical and Sensory Properties

open access: yesMolecules, 2023
Oat husk (hull) is a byproduct of oat processing that is rich in insoluble fiber. The aim of the study was to evaluate the effect of partially replacing wheat flour with oat husk (at levels of 0, 5, 10, 15, and 20 g/100 g) on the physicochemical ...

Geometry, Isometries and Gauging of (2,1) Heterotic Sigma-Models [PDF]

open access: yes, 1996
The geometry of (2,1) supersymmetric sigma-models is reviewed and the conditions under which they have isometry symmetries are analysed. Certain potentials are constructed that play an important role in the gauging of such symmetries.

Characterization of Structure and Antioxidant Activity of Polysaccharides From Sesame Seed Hull

open access: yesFrontiers in Nutrition, 2022
Sesame seed hull is the major by-product of sesame seed processing and is rich in polysaccharides. In this work, sesame hull polysaccharides (SHP) were extracted by ultrasound-assisted alkali extraction methods with a yield of 6.49%.

Numerical Simulation of Mutual Influence in 470 Sailing Hull and Rudder at Different Hull Speeds

open access: yesProceedings, 2020
A 470 sailing race requires effective cooperation between athletes to optimize the hull position and the correct heading. To understand the effect of the hull on the maneuverability of the rudder and the influence of the rudder on the stability and ...

Set Estimation Under Biconvexity Restrictions

open access: yes, 2020
A set in the Euclidean plane is said to be biconvex if, for some angle $\theta\in[0,\pi/2)$, all its sections along straight lines with inclination angles $\theta$ and $\theta+\pi/2$ are convex sets (i.e, empty sets or segments). Biconvexity is a natural

The Effect of Hull Biofouling on Parameters Characterising Ship Propulsion System Efficiency

open access: yesPolish Maritime Research, 2015
One of most important issues concerning technical objects is the increase of their operating performance. For a ship this performance mainly depends on the efficiency of its main pro-pulsion system and the resistance generated during its motion on water.
