In situ biospectroscopic investigation of rapid ischemic and postmortem induced biochemical alterations in the rat brain.

Rapid advances in imaging technologies have pushed novel spectroscopic modalities such as Fourier transform infrared spectroscopy (FTIR) and X-ray absorption spectroscopy (XAS) at the sulfur K-edge to the forefront of direct in situ investigation of brain biochemistry. However, few studies have examined the extent to which sample preparation artifacts confound results. Previous investigations using traditional analyses, such as tissue dissection, homogenization, and biochemical assay, conducted extensive research to identify biochemical alterations that occur ex vivo during sample preparation.

Effects of electrical and mechanical stunning methods on meat quality in ostriches.

The effect of electrical and captive needle air pressure stunning methods on some meat quality parameters was examined in ostriches under practical conditions. One hundred and fifteen ostriches were used in three experiments. The ostriches were stunned either electrically (head only) or by using a captive needle with air pressure.

Work load evolvers from objectively describable and measurable tasks, which can be adjusted in intensity or duration. These tasks must be performed by different people; showing identical loads, as a rule, produce different effects on different people. This fact, i.
