AbstractA novel directional inoculation technique has been designed to cast thin slab ingots containing Goss (or near Goss) oriented components in the as cast microstructure under the combined effect of oriented nucleation and oriented growth. The same has been targeted so as to retain Goss orientations and simultaneously develop γ fiber components (ranging from {111}<$$1\overline{1}0$$ 1 1 ¯ 0 > to {111}<112>) during hot rolling. The designed scheme of directional inoculation achieved oriented nucleation by the effect of exogenously added soft magnetic inoculants under magnetic field and oriented growth by the effect of fast cooling rates prevailing in the mould. The choice of 65Fe–35Co (wt%) system as soft magnetic inoculants was made taking into account the similarity in crystal structure and lattice parameter. The chemically synthesized inoculants under the effect of external magnetic field during solidification were able to exhibit directional inoculation. Variation in the cast microstructure and microtexture by varying the extent of inoculant addition was studied by EBSD technique. The ingots cast under different conditions were subjected to a designed hot rolling schedule and the through process microstructural and microtextural evolution was assessed. It was observed that fine equiaxed grains with initial cube orientations in the as cast structure could lead to the most desirable microstructural as well as microtextural gradient in the hot band.

Using an artificial inoculation technique, a kinetic infection study of Heveabrasiliensis (Willd. ex Adr. de Juss) Mull. Arg. by Rigidoporuslignosus (Kl.) Imazeki has shown the existence of a three-stage infection process: (i) a particularly fast contamination stage. After 15 days of exposure, all plants showed rhizomorphs to be present on taproots; (ii) the spread of epiphytic mycelium all over taproots is associated with numerous punctual penetrations allowing tissue invasion and infection. Beginning at the apex, a rot develops and progresses upward; in less than 3 months, it affects nearly 40% of the invaded plants' taproot. In response to this, the host develops reaction mechanisms which become evident at the cellular level and on the entire plant; and (iii) at this time, a state of equilibrium is reached between the host and the parasite which is shown through a stagnant disease progress. The efficiency of the various host reactions observed in the plants is discussed. [Journal translation]

Phytophthora root and stem rot, caused by Phytophthora sojae, is an important disease of soybean (Glycine max L.) in South Dakota. Because P. sojae populations are highly diverse and resistance genes deployed in commercial soybean varieties often fail to manage the disease, this study was initiated to determine P. sojae pathotype distribution in South Dakota. A total of 216 P. sojae isolates were baited from soil collected from 422 soybean fields in South Dakota in 2013-2015 and 2017. The pathotype of each isolate was determined by inoculating 10 seedlings of 13 standard soybean P. sojae differential lines using the hypocotyl inoculation technique. Of the 216 pathotyped isolates, 48 unique pathotypes were identified. The virulence complexity of isolates ranged from virulence on one Rps gene (Rps7) to virulence on 13 Rps genes and mean complexity was 5.2. Harosoy (Rps7), Harlon (Rps1a), Williams 79 (Rps 1c), William 82 (Rps1k), Harosoy 13XX (Rps1b), were susceptible to 98, 80, 78, 73, 72% of the isolates, respectively. These results highlight the highly diverse P. sojae pathotypes in South Dakota and the likely Rps genes to fail in commercial soybean varieties

Cotton Mather (1663-1728), usually remembered for his theological and historical writings, was also much concerned with medicine. He was interested in many aspects of contemporary science and became one of the few colonial members of the Royal Society of London. In 1721, when a smallpox epidemic hit Boston, Mather urged Boston physicians, particularly Zabdiel Boylston, to employ the inoculation technique used by the Turks as a means of preventing fatal cases of the disease. In his Diary, Mather records the anguish he suffered for having taken this stand. [May] 26 [1721]. The grievous Calamity of the Small-Pox has now entered the Town. The Practice of conveying and suffering the Small-pox by Inoculation, has never been used in America, nor indeed in our Nation, But how many Lives might be saved by it, if it were practised? . . . [June] 13. What shall I do? what shall I do, with regard unto Sammy? He comes home, when the Small-pox begins to spread in the Neighbourhood; and he is lothe to return unto Cambridge. I must earnestly look up to Heaven for Direction. . . . [July] 16. At this Time, I enjoy an unspeakable Consolation. I have instructed our Physicians in the new Method used by the Africans and Asiaticks, to prevent and abate the Dangers of the Small-Pox, and infallibly to save the Lives of those that have it wisely managed upon them. The Destroyer, being enraged at the Proposal of any Thing, that may rescue the Lives of our poor People from him, has taken a strange Possession of the People on this Occasion.
