Abstract:

Red bright color is an important quality attribute that influences beef purchasing and is affected by beef pH. Therefore, the aim of this study was to determine if high ultimate pH affected color stability of longissimus lumborum (LL) steaks from pasture-fed Nellore bulls and if HiOx atmosphere package improved the color stability of high pHu muscles. To achieve these objectives, 18 LL muscles from Nellore bulls were grouped into 3 pHu ranges: normal (n = 6; 5.40 < pHu <5.79), intermediate (n = 6; 5.80 < pHu <6.19) and high (n = 6; pHu > 6.20). All the muscles were cut into 2.5 cm steaks and p

Abstract:

This paper seeks to understand the role that the agriculture sector can play in romoting China's climate change mitigation efforts. In order to understand the history of agricultural and climate change policies in China, the beginning sections are devoted to these topics. In the following chapter,the impact of climate change on agricultural production is explored. Using research data that determine the primary sources of emissions within agriculture, and mitigation practices that have proved effective, potential GHG mitigation measures are proposed in the fourth chapter.Based on recommendation

Abstract:

Slags plays a significant role at high temperature processes. The estimation of the slag viscosity is vital for the safe run of e.g. entrained flow gasifiers. One opportunity of determination is rotational viscometry. This technique is disadvantageous in view of elevated temperatures, applied materials and the necessary time. Additionally, the viscosity can be predicted by the help of viscosity models, where viscosity is a function of slag composition and temperature. Due to changing slag properties within the technical processes, the calculated viscosities can hugely differ from measured ones

Abstract:

The aim of the research was the development of new products and processes from a manufacturing waste. The manufacturing waste were produced by a metallurgic Italian company which produced thin silver metallic films. These films were used as coating and food decoration. Thin films were produced by an hammering process. The starting material, silver laminate, had a thickness of 10 μm. During the hammering process films with various thickness were obtained. The final produced silver films had a thickness of about 300 nm which can be considered a submicrometric dimension, near to the nanometri

Abstract:

Corals face serious worldwide population declines due to global climate change in combination with direct anthropogenic impacts. Global climate change is difficult to manage locally, but policy makers can regulate the magnitude of local stressors affecting reefs. The objective of this experiment is to investigate if reducing sedimentation will enable reef corals to better endure global climate change. It has been shown that some coral species can handle climate change stress when provided with additional energy resources. Here I tested if the capacity of corals to cope with climate change can

The parameter of recent injury was used to provide preliminary information on buoy effectiveness. Results were as follows: approximately 6% of the study area was covered by stony corals, with an average of 3 colonies per square meter.

Recently, it was found that the carrier substrate of zirconia could cause some effects on MLCC sintered at high temperature. Besides, the substrates which were used will easily degrade. The reason for this may be due to the high temperature phase-transformation of zirconia. This article studies the microstructure
