متن کاملShort Term Preservation of Hide Using Vacuum: Influence on Properties of Hide and of Processed Leather
The objective of this work was to investigate vacuum influence on hide preservation time and how it affects hide structure. It was established that vacuum prolongs the storage time without hide tissue putrefaction up to 21 days when the storage temperature is 4°C. The microorganisms act for all storage times, but the action is weak and has no observable influence on the quality of hide during t...

From as early as 2700 BC until fairly recently leather was also in the forefront of information technology with its use (as skins, vellum and parchme...
متن کاملThe effects of treating bovine hide with steam at subatmospheric pressure on bacterial numbers and leather quality.
AIMS To examine the effect of subatmospheric steam treatment on total viable counts (TVCs) on bovine hide and on the quality of derived leather. METHODS AND RESULTS Pieces of bovine hide were heated to 75 degrees C (+/-2 degrees C) (n = 3) or 80 degrees C (+/-2 degrees C) (n = 3) for periods of 1, 10 or 20 s by the application of steam at subatmospheric pressure in a laboratory scale apparatu...
متن کاملNesiritide – Run and hide?
Data extraction: Data were extracted from FDA and sponsor documents and corroborated with published articles when available. Thirty-day survival was assessed by metaanalysis using a fixed-effects model and time-dependent risk by Kaplan-Meier analysis with Cox proportional hazards regression modeling. Where deaths were described within a range of days after treatment, an extreme assumption was m...
