Odorant pens are used by medical practitioners and researchers to assess olfactory dysfunction. Despite their routine use, there are currently no data on the gas-phase odorant concentrations released from the pen tips or whether these concentrations scale linearly with the aqueous-phase concentrations inside the pens. The commercially available Sniffin' Sticks odor threshold test containing n-b...

THE TITLE COMPOUND (SYSTEMATIC NAME 11-cyclo-propyl-4-methyl-5,11-dihydro-6H-dipyrido[3,2-b:2',3'-e][1,4]diazepin-6-one butanol 0.3-solvate), C(15)H(14)N(4)O·0.3C(4)H(9)OH, was crystallized in a new triclinic pseudopolymorphic form, a butanol solvate, and the crystal structure determined at 150 K. The mol-ecular conformation of this new form differs from that reported previously, although the m...

The ethanolic extracts, various fractions and two pure compounds isolated from the plant N. arbortris were tested against Encephalomyocarditis Virus (EMCV) and Semliki Forest Virus (SFV). Pronounced in vitro virus inhibitory activity was observed with the ethanolic and n-butanol fractions as well as with the pure compounds arbortristoside A and arbortristoside C. In addition, ethanolic extracts...

The detailed mechanisms of n-heptane and n-butanol were reduced for the target condition ignition delay time using direct relationship diagram method based on error transfer, coupling transfer sensitivity analysis, total material analysis method. (132 species 585 reactions) (82 383 used to verify concentrations major species, respectively. results showed that mechanism has a good prediction abi...

Evidence was obtained for countercurrent diffusion of 14C-n-butanol in the rabbit renal cortex. After injection into the renal artery of perfused, isolated rabbit kidneys, concentrations of both 14C-butanol and tritiated water in the initial samples collected from the renal venous outflow exceeded those of 125I-albumin when the rate of perfusion was low. When flow was increased, the 125I-albumi...

Capillary-driven action is an important phenomenon which aids the development of high-performance heat transfer devices, such as microscale pipes. This study examines capillary rise dynamics n-butanol/water mixture in a single vertical tube with different radii (0.4, 0.6, and 0.85 mm). For liquids, distilled water, n-butanol, their blends varying concentrations butanol (0.3, 0.5, 0.7 wt.%) were...

The impact of n-butanol, a next-generation biofuel, with watermelon methyl ester in constant-speed diesel engine was analyzed. Methyl from seed oil is considered to be promising alternative source the standard due similar characterization. n-butanol additive added small proportions as an oxygenated fuel for reducing emissions, improving thermal efficiency, and accelerating combustion process. N...

Carbohydrat,es are fermented by Clostridium acetobutylicum and related microorganisms with the formation of acetic acid, n-butyric acid, acetone, ethanol, and n-butanol. It has been conclusively proved that the butanol arises by the reduction of the butyric acid (1, 2). As yet, however, there is no exact information as to the sequence of reactions by which butyric acid is formed from glucose by...

Isobaric vapor–liquid equilibrium (VLE) data for 2-propanol + 1-butanol, 2-propanol + 1-pentanol, 1butanol + 1-pentanol and 2-propanol + 1-butanol + 1-pentanol were measured at 101.3 kPa by using an improved Rose still. All the binary VLE data have passed the traditional area test proposed by Herington. The interaction parameters for the Wilson, NRTL and UNIQUAC equations were determined by reg...
