Controlling beer filtration process through implementation of enzymatic and microbiological techniques

different stabilisants to control stability Microbiologic quality monitoring Intervention to hygiene measure Reorganizations of filter-aid dosage There are several processes that can be used to reduce solids loading in the beer, e.g., settlement by gravity or centrifugation (or combination of them), extended lagering periods, addition of flocculants enzymes and clarifiers to reduce both, yeast and haze loadings. It is the duty of a chemical engineer to select and combine all these processes in order to take an optimal beer consistency that will lead in an

On Identity Statements: In Defense of a Sui Generis View

Abstract

This paper is about the meaning and function of identity statements involving proper names. There are two prominent views on this topic, according to which identity statements ascribe a relation: the object-view, on which identity statements ascribe a relation borne by all objects to themselves, and the name-view, on which an identity statement ‘a is b’ says that the names ‘a’ and ‘b’ codesignate. The object- and name-views may seem to exhaust the field. I make a case for treating identity statements as sui generis instead of attempting to explain them by means of the idea that they ascribe a relation. My contention is that once we do this, no analysis is required.

Hazy Underwater Image Enhancement Based on Contrast and Color Improvement Using Fusion Technique

Abstract

Scattering and absorption of light in water leads to degradation of images captured under the water. This degradation includes diminished colors, low brightness and undistinguishable objects in the image. To improve the quality of such degraded images, we have proposed fusion based underwater image enhancement technique that focuses on improving of the contrast and color of underwater images using contrast stretching and Auto White Balance. Our proposed method is very simple and straightforward that contributes greatly in uplifting the visibility of underwater images.

Some Aspects of Nutritive and Biological Value of Carrot Cultivars with Orange, Yellow and Purple-Coloured Roots

Some Aspects of Nutritive and Biological Value of Carrot Cultivars with Orange, Yellow and Purple-Coloured Roots

The aim of this work was to determine antioxidant activity and some physical and chemical parameters influencing nutritive and biological value of orange, purple and yellow carrot cultivars. The two-year experiment was carried out in Warsaw Agricultural University in 2005 and 2006. Carrot was grown in the experimental field of the University. Six carrot cultivars, differed in storage roots colour and shape, were chosen for the experiment: 'Florida' F1, 'Interceptor' F1, 'Nebula' F1, 'Purple Haze' F1, 'Yellowstone', 'Mello Yello' F1. Immediately after harvest of carrots there were determined: dry matter, total sugars content, total phenolics, total carotenoids, antioxidant activity (DPPH), fractions of dietary fibre, pectines, pH, redox potential, electrical resistance. P-value, which is a combined parameter of some physical and chemical traits, was also calculated. Correlations between some of these quality parameters were determined. Dry mater content was the highest for 'Purple Haze' in 2005, but in 2006 for 'Nebula' similar dry matter content was found. Total sugars content in carrots in 2005 was the highest in 'Purple Haze' but in 2006 'Florida' showed higher sugars content. Total phenolics content was the highest in 'Purple Haze' roots. Total carotenoids content was greatly differentiated between cultivars and varied from below 1 mg·100 g-1 to above 14 mg·100 g-1. For cultivars of yellow storage roots the lowest level of carotenoids were found, and the highest for orange-coloured 'Florida', 'Interceptor' and 'Purple Haze'. In all cultivars, from fractions of total fibre, the highest amount was found in the case of cellulose and pectines. The highest antioxidant activity showed purple-coloured cultivar 'Purple Haze', and the lowest activity yellow-coloured cultivars 'Yellowstone' and 'Mello Yello'. Regression analysis showed that antioxidant activity of carrot storage roots was strictly related to carotenoids content (r=0.92) and phenolics content (r=0.87).

Using Lotteries in Logic of Halakhah Law. The Meaning of Randomness in Judaism

Abstract

There are many phenomena in the Bible connected to the idea of the random, generally in a positive light, but sometimes in a negative one. Both in the Talmudic literature and in the Halakhah texts, the ḥazal (the Sages) also relate to random processes. As we will see here, for them every chance event has a clear meaning, usually even a holy one. In fact, every culture in the world relates to randomness. However, from the Greek philosophers until the rationalism of the 19th century, a process of denuding randomness of its holiness has been taking place. In Judaism, a lottery is not a blind process; moreover the randomness has a clear and profound theological meaning.
