The Preparation of Meat-scraps. Meat-scraps Problems. De Bereiding van Diermeel. Diermeelproblemen. Dr. B. J. C. te Hennepe. Tijdschrift voor Diergeneeskunde, 1931, p. 918.The author describes three different processes for the preparation of meatscraps used in the Netherlands, pointing out their advantages and disadvantages. (1) The wet process, (2) The dry process, (3) The extraction process by means of Benzin. A summary of the economical results obtained is being given. The author points further out, that according to his opinion the question, as to how far the intrinsic value of free fatty acids influences the feeding value of the meal, especially as regards chicken food, is quite entitled.

The technological parameters, namely temperature and duration of β-carotene extraction process from the biomass of filamentous fungus Blakeslea trispora with vegetable oils of various fatty acid compositions and with various contents of natural antioxidants (refined deodorized sunflower, viso-oleic sunflower, corn and sesame) have been investigated. Statistical models of dependences of β-carotene, as well as analytical numbers, characterizing the content of free fatty acids (acid number) and primary products of lipid oxidation (peroxide number) content, in oil extracts of the specified refined deodorized oils, from temperature and extraction duration have been built. Rational parameters of β-carotene extraction from Blakeslea trispora biomass with selected extractants (refined deodorized sunflower, high oleic sunflower, corn and sesame oils) have been determined for the extracts technological properties control. It has been proven that the use of these refined deodorized oils as extractants practically does not affect the content of the target product in oil extracts of biomass, but it does affect the analytical numbers of extracts characterizing the content of free fatty acids, peroxides and hydroperoxides. The highest content of free fatty acids in β-carotene containing biomass extraction with sunflower oil has been observed. The minimum content of free fatty acids in extracts with corn and sesame oils using  has been be achieved. The highest content of primary products of lipid oxidation (peroxides and hydroperoxides) during β-carotene containing biomass extraction by sunflower oil has been observed. The minimum content of free fatty acids in extracts with sesame oil using has been achieved. It is possible to predict β-carotene content, as well as acid and peroxide numbers of oil  extracts from biomass in specified refined deodorized oils, depending on temperature and extraction process duration using the obtained approximation dependences.

In this paper we are discussing wet and dry process of Portland cement manufacture. Wet process minerals are wet ground to form a slurry and in dry process minerals are dry ground to form a powder like substance. In this paper, we are discussing the comparison between wet process and dry process with various advantages and disadvantages.

ABSTRACT In addition to the previously described permeability disturbance in the blood aqueous barrier of the eye, measured as an increase of the aqueous flare, a series of transitory systemic effects have been recorded following the subcutaneous injection of synthetic α-MSH: marked increase of the free fatty acids in plasma, decrease in the serum calcium level, decrease in the blood pressure, increase in the skin temperature, increased frequency and diminished amplitude of respiration, presence of slow waves in the EEG. There is a correlation between the magnitude of the aqueous flare increase and the increase of free fatty acids in plasma and also between the aqueous flare and the minimum serum calcium level.
