Robert Taft response to Attorney General Langer on the grade and price of grain, 1917

Robert Taft of the U.S. Food Administration wrote this letter to Attorney General William Langer on October 29, 1917, regarding the price and grade of grain. This letter was in response to a letter Langer had sent on October 24, 1917. Taft advised the Attorney General to petition the Secretary of Agriculture to change the grade.https://commons.und.edu/langer-papers/1035/thumbnail.jp

Robert Taft to Attorney General Langer on milling rules, 1917

This letter was written on November 23, 1917, by Robert Taft of the United States Food Administration in response to Attorney General William Langer\u27s previous letters. Langer had issues with some of the milling rules that had been established and Taft advised him to get good testimony to support his request for change.https://commons.und.edu/langer-papers/1039/thumbnail.jp

Oocyte morphology and estrogen concentrations following a reduction in progesterone in beef cattle

Low dosages of progestogens promote persistent follicles, high systemic estrogen and low fertility. The objectives of this study were to determine effects of a reduction in progesterone on (1) morphology of oocytes and intrafollicular concentrations of estradiol. Cows on low progesterone (n = 12) received used intravaginal progesterone inserts on d 4 after estrus and prostaglandin (PG) F2alpha (25 mg, i.m.) on d 6. Control animals (n = 12) received saline on d 6. The oocyte and follicular fluid were recovered from the largest follicle on d 8 or d 10.;Serum estradiol was lower during d 4--6 but greater (P \u3c .01) during d 7--10 in cows treated with progesterone inserts and PGF 2alpha while the largest follicle was larger in treated cows on day 10 only (14 vs. 12 mm; P \u3c .05). Intrafollicular concentrations of estrogen were greater in treated than in control cows (990 +/- 87 vs 191 +/- 106; P \u3c .01). Progesterone in follicular fluid (mean = 42 ng/ml) did not differ. Oocytes were observed in oocyte nuclear stage I in the control group on d 8. All other oocytes were in nuclear stage II. In addition, the degree of clumping of mitochondria, the percentage of intact cumulus cell processes and percentage of normally shaped mitochondria was greater in oocytes from d 8 control cows than in all other groups.;Changes in concentrations of estradiol and oocyte morphology typically associated with the preovulatory period had occurred within 2 d after a reduction in progesterone, even when low peripheral concentrations of progesterone were maintained. These earliest stages of oocyte maturation occurred in response to a reduction in progesterone. Similar changes in oocyte morphology were observed in control animals by d 10 of the estrous cycle, probably representing the onset of atresia

On antipodes in pointed Hopf algebras

AbstractIf S is the antipode of a Hopf algebra H, the order of S is defined to be the smallest positive integer n such that Sn = I (in case such integers exist) or ∞ (if no such integers exist). Although in most familiar examples of Hopf algebras the antipode has order 1 or 2, examples are known of infinite dimensional Hopf algebras in which the antipode has infinite order or arbitrary even order [1, 4, 6] and also of finite dimensional Hopf algebras in which the antipode has arbitrary even order [3, 5]. Some sufficient conditions for the antipode to have order ⩽4 are known [2, 4], but the following questions remain open: Does the antipode of a finite dimensional Hopf algebra necessarily have finite order? If the antipode S of a Hopf algebra H has finite order is that order bounded by some function of dim H?In this paper, by constructing a certain basis for an arbitrary pointed coalgebra and studying the action of the antipode on the elements of such a basis for a pointed Hopf algebra, we obtain affirmative answers to the second question in case H is pointed and to the first question in case H is pointed over a field of prime characteristic.We use freely the definitions, notation, and results of [4]
