HMF has been discovered for the first time in 1895 by Diill and Kiermeyer who independently introduced a method of synthesis of HMF that they named oxy-methylfurfurol [65, 66]. Later, Haworth and Jones studied the mechanism of this reaction and showed that the formation of HMF involved a triple dehydration of hexoses [67]. Other studies performed by Van Dam, Kuster and Antal showed that the dehydration of hexoses (especially fructose and glucose) involved two possible pathways (Scheme 5) [63, 68, 69]. The path 1 involves the dehydration of ring systems (fructopyranose or glucopyranose), while the path 2 is based on acyclic derivatives (glucose and fructose open chain). 

Duarte and Jones studied the galactan from the snail Strophocheilus oblongus, and obtained a polymeric residue in a yield of 8% after... 

In a urine specimen obtained from Jones study (12), the hexane fraction (H) — after enzyme hydrolysis — showed a level of 10 ng of unmetabolized A9-THC per ml of urine (with a marginally positive Confidence Index) and 12 ng/ml of cannabinol (CBN) with a high Confidence Index and hence a clearcut identification. 

Wang and Jones studied solid-state chemistry of compound 2 and found that irradiation of single crystals of 2 gave the single crystals of the photodimer (87T1273). 

Fenimore and Jones studied reaction (160) in a low-pressure flame and arrived at... 

The intimate details of the decarboxylation mechanism of the free acid are not completely clear. Westheimer and Jones studied the effect of changing solvent polarity on the rate of decarboxylation of a,a-dimethylacetoacetic acid (Table 44). 

Pyridine ylide methodology is not needed to visualize chlorophenylcarbene but, as expected, LFP of chlorophenyl diazirine 16 in the presence of pyridine produces expected ylide 17. Michelle Jones studied for this reaction as a function of solvent. The reaction is slightly faster in non-polar solvents (Table... 

The reason for these apparently contradictory results is the different conditions used to perform the radical cyclisation. In Jones studies, 1.2 equiv. of BusSnH and trace amounts of AIBN were used, while in Tsuge s work, 1.5 equiv. of BusSnH and 0.25 equiv. of initiator were used. This difference could explain the disparity, since the initiator probably takes part in the oxidation mechanism. 

Alfaro and Jones studied the XO reaction for a series of 6-substituted 4-quinazolinones, which have been investigated experimentally. They used the B3LYP method with the aug-cc-pVDZ basis set and included the ZPE to model kinetic isotope effects. For formamide, they obtained a barrier of 133 kJ mol for the concerted mechanism. However, the difference compared to the previous results came primarily from the change in reference state to the separated reactants. For the 4-quinazolinones, they obtained barriers of 92-140 kJ mol. The barriers calculated with the TPSS method were 10 kJ mol" lower. 

The single layer glass bead model is a closer representation of a porous medium. This was used by Sharma to study toe foam drive process and Egbogah and Dawe to study toe size distribution of oil droplets. Mattax and Kyte used a network of etched capillaries to study fluid distributions under various wettability conditions. Davis and Jones studied the flow of foam in porous media using etched glass micromodels. A study of toe multiphase flow of oil and water di ersed in toe porous medium was carried out by Bonnet using an etched plastic micromodel. 

Solubilization in polymer-surfactant aggregates within the aqueous solution has been documented for a long time. As early as 1968, Jones studied dye solubilization (orange... 

The duration of treatment can also influence the outcome. Most studies were for three months, and two followed patients for longer periods (29,30). Clini et al. noted an improved quality of life after two years and improved dyspnea after one year, with a trend to a reduction in hospital and ICU admissions over the subsequent year. Days in hospital due to respiratory exacerbations also showed a nonsignificant trend in favor of NIPPV (12.6 7.9 vs. 16.9 10.3). Clinical benefits were seen after three months in the Meecham Jones study (11). 

Ballone and Jones studied ROP of cyclic oligomers of Bisphenol A polycarbonate using density functional calculations of the structure, potential energy surface, and reactivity of species. In their Monte Carlo simulations, the authors demonstrated that entropy in redistribution of interparticle bonds was the driving force for chain formation in the studied polymerization of macrocycles.
