Effects of Replacing Alfalfa Hay With Barley Silage in High‐Concentrate Diets: Chewing Behavior, Ruminal Fermentation, Total‐Tract Digestibility, and Milk Production of Dairy Cows in Mid‐Lactation Phase

open access: yesAnimal Research and One Health, EarlyView.
We assessed lactation productivity in dairy cows when replacing alfalfa hay with barley silage. A 50% replacement increased feed intake, whereas total replacement improved nutrient conversion to milk. Barley silage can effectively replace alfalfa hay, enhancing sustainability and resilience in dairy production amid forage quality constraints and market

MHD precursor to disruption in Iran tokamak 1 [PDF]

open access: yesarXiv, 2004
The purpose of this paper is to further investigate the major disruptions occurring in low-q(a) discharges in Iran Tokamak 1, and to compare the theoretical and experimental results for the rate of island growth. The study of precursor phase of disruption can be predicted and avoided using suitable control systems.

Multiple model predictive control for offshore wind turbines operating in the full‐load range

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper presents a multiple model predictive control (MMPC) strategy based on an individual blade pitch (IBP) mechanism to control floating offshore wind turbines (FOWTs) when operating in the full‐load range (above the rated wind speed).

Some New Inequalities Between Important Means [PDF]

open access: yesMathematical Inequalities & Applications (MIA), Volume 10, Number 3 (2007), 517-527, 2007
In this paper, mainly using the convexity of the function $\frac{a^x-b^x}{c^x-d^x}$ and convexity or concavity of the function $\ln\frac{a^x-b^x}{c^x-d^x}$ on the real line, where $a>b\geq c>d>0$ are fixed real numbers, we obtain some important relations between various important means of these numbers.
