Matter culture

The physiological significance of the growth requirements for established animal cell lines in serum-free medium is still an unresolved matter. Cultures of... 

Engineering students need also to reflect on the fact that, Norms and beliefs -about what is a robust design, about the capabilities of the user, of dlizens [-] matter. Ethics matters. Culture matters (Bucciarelli 2011, p. 22). To bring this focus into engineering education Bucciarelli suggests the establishment of a liberal arts program in engineering ... 

Plants, in contrast to animals, have the ability to convert carbon dioxide from the atmosphere and inorganic components of the earth direcdy into high energy carbohydrates (qv), fats, and proteins (qv). These plant materials are absolutely essential to human nutrition as well as to the nutrition of other animal species. Thus consumption of plant matter, either directly or through a food chain, is essential to animal life and humans are totally dependent on agricultural endeavors, ie, the culture and harvesting of plant matter. 

Available Chlorine Test. The chlorine germicidal equivalent concentration test is a practical-type test. It is called a capacity test. Under practical conditions of use, a container of disinfectant might receive many soiled, contaminated instniments or other items to be disinfected. Eventually, the capacity of the disinfectant to serve its function would be overloaded due to reaction with the accumulated organic matter and organisms. The chlorine germicidal equivalent concentration test compares the load of a culture of bacteria that a concentration of a disinfectant will absorb and still kill bacteria, as compared to standard concentrations of sodium hypochlorite tested similarly. In the test, 10 successive additions of the test culture are added to each of 3 concentrations of the hypochlorite. One min after each addition a sample is transferred to the subculture medium and the next addition is made 1.5 min after the previous one. The disinfectant is then evaluated in a manner similar to the phenol coefficient test. For equivalence, the disinfectant must yield the same number of negative tubes as one of the chlorine standards. 

This problem involves consideration as to the effect of external conditions such as light, heat, moisture, altitude, manuring and other cultural matters, and as is obvious, such considerations may, and do, vary greatly with different plants. Such considerations are to some extent within the scope of the knowledge and skill of the well-trained farmer and the careful distiller. But there are other considerations of a much more abstruse character to be taken into account, and here only the chemist can undertake the necessary investigations. The questions which present themselves for solution are, broadly, some such as the following —... 

The pH of 1.2 liters of filtrate containing 3.B mg/ml of cytidine diphosphate choline, obtained by removing solid matters from the culturing liquor, was adjusted to a pH of B.5 with a 0.5N KOH solution. The filtrate was passed through a column of strongly basic anion exchange resin, Dowex 1 x 2 (formic acid type). After washing the resin with water, a formic acid... 

Soft drinks are among the most recognized products of Western culture. Beginning as tonics for fatigue (and anything else that might be the matter with a patient), n they have evolved into sweet bubbly accompaniments to hamburgers, fries, and other fast foods. 

The events which occur prior to the death of short-term cultures have been referred to as the process of cellular aging, or apoptosis. Whether in vitro cellular aging is due to an inherited genetic program, or whether in vitro aging is simply a consequence of an imperfect cell culture environment is a matter of controversy. The possibility that the cellular aging which occurs in vitro resembles cellular aging in vivo is unresolved. 

The testing of disinfectants for virucidal activity is not an easy matter. As pointed out earlier (Chapter 3), viruses are unable to grow in artificial culture media and thus some other system, usually employing living cells, must be considered. One such example is tissue culture, but not all virus types can propagate under such circumstances and so an alternative approach has to be adopted in specific instances. The principles of such methods are given below. 

These observations clearly indicate that the disease is determined mostly by the environment and not by the race of the population. Since the geographic environment per se is ruled out, it seems that the cultural environment is the one that matters. 

Therefore, it is not always possible to construct an ES, even if experts exist and are willing to cooperate. There are also difficulties that arise if the "correct" answer to a question as determined by an expert is colored by personal preference or cultural views. An ES that could provide advice about classical and modern art might have many uses, but if it started passing comment on whether a sheep pickled in formaldehyde is "good" or "bad" art, it might antagonize users. Judging whether a dead sheep is beautiful, or whether it is art at all, is very much a matter of personal preference.
