Aflatoxin B < sub > 1 </ sub >, the most toxic, is a potent carcinogen and has been directly correlated to adverse health effects, such as liver cancer, in many animal species.

in 1968 The group of Barry Trost of Stanford University is responsible for the stereoselective total synthesis of (+)- Aflatoxin B < sub > 1 </ sub > and B < sub > 2a </ sub > in 2003 .< ref > Trost, B.

The pronounced forms of Aflatoxins are those of B1, B2, G1, and G2, amongst which Aflatoxin B1 predominantly targets the liver, which will result in necrosis, cirrhosis, and carcinoma .< ref name = afltx >

In the US, the acceptable level of total aflatoxins in foods is less than 20 μg / kg, except for Aflatoxin M1 in milk, which should be less than 0. 5 μg / kg .< ref name = cfh >

The total synthesis of Aflatoxin B2 is a multistep sequence that begins with a cycloaddition between the quinone 1 and the 2, 3-Dihydrofuran.

Aflatoxin ( a potent carcinogen ) was administered to these rats over a 2 week dosing period.

Aflatoxin total synthesis concerns the total synthesis of a group of organic compounds called aflatoxins.

Vitamin B < sub > 12 </ sub > deficiency may cause, among several neurological abnormalities, overlapping cerebellar and sensory ataxia.

A rare exception to the dominance of α-amino acids in biology is the β-amino acid beta alanine ( 3-aminopropanoic acid ), which is used in plants and microorganisms in the synthesis of pantothenic acid ( vitamin B < sub > 5 </ sub >), a component of coenzyme A.

For example, at the gene locus for the ABO blood type carbohydrate antigens in humans, classical genetics recognizes three alleles, I < sup > A </ sup >, I < sup > B </ sup >, and I < sup > O </ sup >, that determine compatibility of blood transfusions.

: B + c < sub > 1 </ sub > · i < sub > 1 </ sub > + c < sub > 2 </ sub > · i < sub > 2 </ sub > + … + c < sub > k </ sub > · i < sub > k </ sub >.

Thus, if a two-dimensional array has rows and columns indexed from 1 to 10 and 1 to 20, respectively, then replacing B by B + c < sub > 1 </ sub >-− 3 c < sub > 1 </ sub > will cause them to be renumbered from 0 through 9 and 4 through 23, respectively.

The addressing formula is completely defined by the dimension d, the base address B, and the increments c < sub > 1 </ sub >, c < sub > 2 </ sub >, …, c < sub > k </ sub >.

where k < sub > B </ sub > is Boltzmann's constant, T is the temperature, R is the resistance, and is the bandwidth of the frequency.

His comment on Numbers 23: 19 has a still more polemical tone: “ God is not a man that he should lie ; neither the son of man, that he should repent ; < font face =" times new roman " size = 3 > if a man says: ‘ I am a god ’ he is a liar ; if he says: ‘ I am a son of man ’ he will have cause to regret it ; and if he says, ‘ I will go up to heaven ’ he has said but will not keep his word ” last phrase is borrowed from B ' midbar 23: 19 ( Yer.

It exists in four major polymorphs: α, β, γ and T. Whereas α, β and T phases are based on B < sub > 12 </ sub > icosahedra, the γ-phase can be described as a rocksalt-type arrangement of the icosahedra and B < sub > 2 </ sub > atomic pairs.

Similarly IF A > B THEN A ← A − B.

The Secretary of the Treasury is authorized and directed out of the sums covered into any of the funds pursuant to subsection ( B ) of this section, and after making the deduction provided for in Section 7 ( B ) of this Title -- ( 1 )

The Secretary of the Treasury, upon the concurrence of the Secretary of State, is authorized and directed, out of the sum covered into the Yugoslav Claims Fund pursuant to subsection ( B ) of this section, after completing the payments of such funds pursuant to subsection ( C ) of this Section, to make payment of the balance of any sum remaining in such fund to the Government of the Federal People's Republic of Yugoslavia to the extent required under Article 1 ( C ) of the Yugoslav Claims Agreement of 1948.

With respect to Article 2,, paragraphs 1 ( B ) and 1 ( C ): Uses of Section 104 ( E ) and Section 104 ( G ) rupees: The Government of India will use the amount of rupees granted or loaned to it by the United States pursuant to paragraphs 1 ( B ) and 1 ( C ) for projects to promote economic development with emphasis upon the agricultural sector including food reserve storage structures and facilities as may from time to time be agreed upon by the authorized representatives of the United States and the authorized representatives of the Government of India, in the following sectors: A.

The Government of India further agrees in cooperation with the Government of the United States, to coordinate the use of grant and loan funds provided for in paragraphs 1 ( B ) and 1 ( C ) of Article 2, with such direct dollar assistance as may be made available by the Government of the United States of America, so that both sources of financing may be channeled to specific and clearly identifiable economic development programs and projects.

Some 45 frequencies are assigned for use primarily by dominant Class 1, -- A or Class 1, -- B clear-channel stations, designed to operate with adequate power and to provide service -- both groundwave and ( at night ) skywave -- over large areas and at great distances, being protected against interference to the degree necessary to achieve this objective.

class 1, -- B stations are protected at night to their 0.5-mv./m. 50-percent time skywave contours against cochannel interference.

On the remainder of the clear channels, the dominant ( class 1 ) -- B stations are protected as described above, and the relatively small number of secondary ( class 2 ) ) stations permitted to operate on these channels at night are required to operate directionally and/or with reduced power so as to protect the class 1, stations.

Between 70 K and room temperature, berkelium behaves as a Curie – Weiss paramagnetic material with an effective magnetic moment of 9. 69 Bohr magnetons ( µ < sub > B </ sub >) and a Curie temperature of 101 K. This magnetic moment is almost equal to the theoretical value of 9. 72 µ < sub > B </ sub > calculated within the simple atomic L-S coupling model.

That is, K < sub > d </ sub >, which has the dimensions of concentration, equals the concentration of free A at which half of the total molecules of B are associated with A.

For example, in a system where there is no queuing, the GoS may be that no more than 1 call in 100 is blocked ( i. e., rejected ) due to all circuits being in use ( a GoS of 0. 01 ), which becomes the target probability of call blocking, P < sub > b </ sub >, when using the Erlang B formula.

If f: A < sub > 1 </ sub > → A < sub > 2 </ sub > and g: B < sub > 1 </ sub > → B < sub > 2 </ sub > are morphisms in Ab, then the group homomorphism Hom ( f, g ): Hom ( A < sub > 2 </ sub >, B < sub > 1 </ sub >) → Hom ( A < sub > 1 </ sub >, B < sub > 2 </ sub >) is given by φ g o φ o f.
