Tetra­butyl­ammonium tris­(methyl­sulfanylmeth­yl)phenyl­borate

In the title molecular salt, C16H36N+·C12H20BS3-, three of the four n-butyl chains show a trans conformation, whereas the fourth has the C—C—C—C torsion angle in a gauche conformation [-77.8 (5)°]. In the crystal, mol­ecules are packed in layers parallel to the (101) plane

[my]-Bis(diphenylphosphanyl)borato-[kappa]2P:P'-bis[dicarbonyl([eta]5-cyclopentadienyl)iron(II)] tetrachloridoferrate(III) chloroform solvate

The title compound, [Fe2(C5H5)2(C24H22BP2)(CO)4][FeCl4]·CHCl3, is an oxidation product of CpFe(CO)2PPh2BH3. One pair of phenyl rings attached to the two different P atoms are almost parallel, as are the other pair [dihedral angles = 8.7 (5) and 8.9 (5)°]. The planes of the two cyclopentadienyl rings are inclined by 26.8 (7)° with respect to each other. The carbonyl groups at each Fe atom are almost perpendicular [C-Fe-C = 92.6 (6) and 94.3 (5)°]. Key indicators: single-crystal X-ray study; T = 173 K; mean σ(C–C) = 0.019 Å; R factor = 0.112; wR factor = 0.177; data-to-parameter ratio = 16.8

Tetra­aceto­nitrile­lithium tetra­iso­thio­cyanato­borate

The crystal structure of the title salt, [Li(CH3CN)4][B(NCS)4], is composed of discrete cations and anions. Both the Li and B atoms show a tetra­hedral coordination by four equal ligands. The aceto­nitrile and iso­thio­cyanate ligands are linear. The bond angles at the B atom are close to the ideal tetra­hedral value [108.92 (18)–109.94 (16)°], but the bond angles at the Li atom show larger deviations [106.15 (17)–113.70 (17)°]

A non-commutative algorithm for multiplying 5x5 matrices using 99 multiplications

We present a non-commutative algorithm for multiplying 5x5 matrices using 99 multiplications. This algorithm is a minor modification of Makarov's algorithm which exhibit the previous best known bound with 100 multiplications

Complete Genomes of Symbiotic Cyanobacteria Clarify the Evolution of Vanadium-Nitrogenase.

Plant endosymbiosis with nitrogen-fixing cyanobacteria has independently evolved in diverse plant lineages, offering a unique window to study the evolution and genetics of plant-microbe interaction. However, very few complete genomes exist for plant cyanobionts, and therefore little is known about their genomic and functional diversity. Here, we present four complete genomes of cyanobacteria isolated from bryophytes. Nanopore long-read sequencing allowed us to obtain circular contigs for all the main chromosomes and most of the plasmids. We found that despite having a low 16S rRNA sequence divergence, the four isolates exhibit considerable genome reorganizations and variation in gene content. Furthermore, three of the four isolates possess genes encoding vanadium (V)-nitrogenase (vnf), which is uncommon among diazotrophs and has not been previously reported in plant cyanobionts. In two cases, the vnf genes were found on plasmids, implying possible plasmid-mediated horizontal gene transfers. Comparative genomic analysis of vnf-containing cyanobacteria further identified a conserved gene cluster. Many genes in this cluster have not been functionally characterized and would be promising candidates for future studies to elucidate V-nitrogenase function and regulation

Circular 52

This is the sixth publication in this format on grain performance trials in the Tanana River Valley. The first, published 5 years ago, included the results o f spring cereal-variety tests conducted at Fairbanks and Delta Junction during the 1978 and 1979 growing seasons. The variety-test results from the 1980, 1981, 1982, and 1983 growing seasons were annual publications. Included in this report are a weather summary, the 1984 variety-test results, and a plant-disease section.Introduction -- Standard Bushel Weights and Conversion from English to Metric Units -- Part I: Climatic Data for and Germplasm Evaluation: Tanana Valley Weather Summary: Table 1: Climatic Data for Delta Junction during the 1984 Growing Season, Table 2: Climatic Data for Fairbanks during the 1984 Growing Season; Barley Performance Trials: Table 3: Long-Term Average and Range of Yields for Barley Standard Varieties Grown at Fairbanks and Delta Junction, 1971-1984, Table 4: Barley Variety Trials Conducted at Delta Junction and Fairbanks during the 1984 Growing Season, Variety Descriptions, Table 5: Barley Varieties Tested at Fairbanks and Delta Junction, 1971-1984 -- Oat Performance Trials: Table 6 : Long-Term Average and Range in Yields for Oat Standard Varieties Grow n at Fairbanks and Delta Junction, 1971-1984, Table 7: Oat Variety Trials Conducted at Delta Junction and Fairbanks during the 1984 Growing Season, Variety Descriptions, Table 8 : Oat Varieties Tested at Fairbanks and Delta Junction, 1971-1984 -- Spring Wheat Performance Trials: Table 9: Long-Term Average and Range in Yields for Wheat Standard Varieties Grown at Fairbanks and Delta Junction, 1971-1984, Table 10: W heat Variety Trials Conducted at Fairbanks and Delta Junction during the 1984 Growing Season -- Variety Descriptions: Table 11: W heat Varieties Tested at Fairbanks and Delta Junction, 1971-1984 -- Part II: Plant-Disease Evaluation: Barley Diseases: Table 12: Summary of Diseases Observed on Barley Varieties under Field Conditions in the Delta-Clearwater Area, Snow M old Disease Com plex on W inter W heat and Lawn G ra s s e s, Diseases on O ther C r o p, Diseases O bserved on Crops during the 1984 Growing Season and T heir S ym ptom
