Since the low pH of the stomach normally kills ingested bacteria, antacids increase the vulnerability to infection.

Since the mid-20th century, there has been considerable debate over how the earliest forms of life evolved and how to classify them, especially at the kingdom and domain levels and organisms that are or have been considered bacteria.

Since 1980, the Dead Sea basin has been dry and the algae and the bacteria have not returned in measurable numbers.

Since E. histolytica does not form cysts in the absence of bacteria, E. invadens has become used as a model for encystation studies as it will form cysts under axenic growth conditions, which simplifies analysis.

Since E. histolytica does not form cysts in vitro in the absence of bacteria, it is not possible to study the differentiation process in detail in that species.

Since then, various life forms have been moved into three new kingdoms: Monera, for prokaryotes ( i. e., bacteria ); Protista, for protozoans and most algae ; and Fungi.

Since the bacteria are blood-borne, several organs can be affected, including the spleen and brain.

Since bacteria were unknown in medieval times, illnesses are evil spirits, which come under Vim.

Since the compounds kill none of the bacteria, any resistant mutations must compete with living, non-resistant individuals.

Since all natural waterways contain bacteria and nutrients, almost any waste compounds introduced into such waterways will initiate biochemical reactions ( such as shown above ).

Since silage goes through a fermentation process, energy is used by fermentative bacteria to produce volatile fatty acids ( VFAs ), such as acetic, propionic, lactic, and butyric, which preserve the forage.

Since uncolonized land may have thin, poor quality soils with few nutrients, pioneer species are often hardy plants with adaptations such as long roots, root nodes containing nitrogen-fixing bacteria, and leaves that employ transpiration.

Since there is a great variety of bacteria, effectiveness against any given type of bacterium does not ensure that it is effective against unrelated types.

Since then, inteins have been found in all three domains of life ( eukaryotes, bacteria, and archaea ) and in viruses.

Since then, Yakult has also introduced a line of beverages for the Japanese market that contain Bifidobacterium breve bacteria, and has also used its lactobacilli research to develop cosmetics.

Since blood is normally sterile, this process does not normally lead to the isolation of bacteria.

Since they are stored at room temperature in nutritive solutions, they are at high risk for growing bacteria.

Since the 2003 discovery of methane in the atmosphere, some scientists have been designing models and in vitro experiments testing growth of methanogenic bacteria on simulated Martian soil, where all four methanogen strains tested produced substantial levels of methane, even in the presence of 1. 0wt % perchlorate salt.

Since bacteria become resistant against a single phage, d ' Herelle suggested using " phage cocktails " containing different phage strains.

Since bacteria that cause urinary tract infections are often the cause of epididymitis in children, co-trimoxazole or suited penicillins ( for example, cephalexin ) can be used.

Since then, Type VI secretion systems have been found in most genomes of proteobacteria, including animal, plant, human pathogens, as well as soil, environmental or marine bacteria.

Since the start codon of the genetic code codes for the amino acid methionine, most protein sequences start with a methionine ( or, in bacteria, mitochondria and chloroplasts, the modified version N-formylmethionine, fMet ).

Since they have only recently been discovered and the large majority have not been cultured, the ecology and metabolism of these bacteria is not well understood.

Since 1985, recombinant human growth hormone ( rHGH ) is a recombinant form of human GH produced by genetically engineered bacteria, manufactured by recombinant DNA technology.

Since it is absorptive and extremely acidic, it inhibits growth of bacteria and fungi, so it is used for shipping seeds and live plants.

Since the Supreme Court's decision of that year this is more doubtful ; ;

( Since the time-span of the nation-state coincides roughly with the separate existence of the United States as an independent entity, it is perhaps natural for Americans to think of the nation as representative of the highest form of order, something permanent and unchanging.

Since it is not far from Viareggio, he will visit Puccini's house, as he never fails to do, to pay his respects to the memory of the composer of La Boheme, which he considers one of Puccini's masterpieces.

Since attack serves to stimulate interest in broadcasts, I added to my opening statement a sentence in which I claimed that German youth seemed to lack the enthusiasm which is a necessary ingredient of anger, and might be classified as uninterested and bored rather than angry.

Since the air is a continuum, the network of communication remains intact regardless of the positions or motions of the points ( the people ) in the net.

Since the hazards of poor communication are so great, p can be justified as a habitable site only on the basis of unusual productivity such as is made available by a waterfall for milling purposes, a mine, or a sugar maple camp.

Since the difficulty of drawing the net is great, we will merely discuss it.

Since a civilizational crisis involves also a crisis in private interests and in the ruling class, reaction is normally found among those who feel themselves to be among the ruling class.

Since civilizational change is the most difficult to perceive and analyze, it seldom is given adequate attention.

Since the slogans have little application to reality and are sanctimonious to boot, the applause is faint even in areas of the world where we should expect to find the greatest affection for free government.

Since more is known about Quiney than about any other acquaintance of Shakespeare in Stratford, his career may be followed to its sudden end in 1602.

Since the great flood of these dystopias has appeared only in the last twelve years, it seems fairly reasonable to assume that the chief impetus was the 1949 publication of Nineteen Eighty-Four, an assumption which is supported by the frequent echoes of such details as Room 101, along with education by conditioning from Brave New World, a book to which science-fiction writers may well have returned with new interest after reading the more powerful Orwell dystopia.

Since Laos is of no more purely military value to Moscow itself than it is to Washington, this approach might be expected to head off Mr. Khrushchev for the moment.

Since little is known about autism, and almost nothing has been written for the layman, we'd like to share one experienced mother's comments.

Since the work is done by hand, the only limitation, it is said, `` is that of human conception ''.

Since the apparatus is new, it requires experimentation and changes in technique.

Since the obvious is not always true, the Republican National Committee wisely analyzed its defeat of last autumn and finds that it occurred, as suspected, in the larger cities.

Since he has just shown who is top dog, he may not be ready to receive this highest honor in the gift of the Soviet people.

Since appeals to morality, to humanity, and to sanity have had such small effect, perhaps our last recourse is the deterrent example.

Since the goal of our international planners is a World Government, this Atlantic Community would mark a giant step in that direction for, once American economic autonomy is absorbed, a larger grouping is a question of time.
