Investigation of Soot Formation During Partial Oxidation of Diesel Fuel
Authors: Roth K. , Wirtz S. , Scherer V. , Nastoll W. 
Published: May 2007

AbstractSoot formation during partial oxidation is a major issue for hydrogen production from liquid hydrocarbon fuels. Measurements were made to investigate the sooting behavior of diesel fuel under variation of the main operating parameters temperature (T = 800 to 1300 °C), pressure (p = 1 to 3 bar), equivalence ratio (Φ =1 to 3), and steam ratio (H2O/C = 0.2 to 0.6) at constant residence time. The experimental setup was a perfectly stirred/plug flow reactor (PSR/PFR system) providing conditions close to reality. The study proves that soot growth rate strongly depends on temperature, pressure, and equivalence ratio while adding water has a minor effect on soot growth. Experimental results were compared with a kinetic model developed by the Institut Français du Pétrole (IFP), predicting soot formation during the partial oxidation of liquid hydrocarbon fuels. The calculated amount of soot shows good agreement with the measured data.
Control of the Molecular Weight Distribution of Petroleum Pitches via Dense‐Gas Extraction
Authors: Cervo E. G. , Thies M. C. 
Published: May 2007

AbstractDense‐gas extraction (DGE) was used to fractionate an isotropic petroleum pitch (number‐average molecular weight Mn = 516) into oligomeric cuts. A countercurrent‐flow packed column was used to effect the separation, with supercritical toluene being used as the dense‐gas solvent and commercially available M‐50 or A‐240 pitch being used as the feed. Isothermal operation at 330, 350, and 380 °C was investigated, as well as operation with a linear positive temperature gradient (+ΔT), with the bottom of the column at 330 and the top at 380 °C. For isothermal operation, the molecular weight distribution of the bottom products consisted primarily of dimer (Mn = 508) and trimer (Mn = 759) species, with pressure changes of as little as 5 bar producing significant changes in their relative distribution, as observed by MALDI mass spectrometry. On the other hand, by operating with a +ΔT, we could produce a bottom product consisting primarily of trimers and tetramers (Mn = 997).

AbstractBACKGROUND.The current study was conducted to determine whether there were differences in outcome for patients with unresectable locally advanced pancreatic cancer (LAPC) who received treatment with chemoradiation therapy (CR) versus induction chemotherapy followed by CR (CCR).METHODS.Between December 1993 and July 2005, 323 consecutive patients with LAPC were treated at the authors' institution with radiotherapy and concurrent gemcitabine or fluoropyrimidine chemotherapy. Two hundred forty‐seven patients received CR as initial treatment, and 76 patients received a median of 2.5 months of gemcitabine‐based induction chemotherapy prior to CR. Most patients received a radiation dose of 30 grays in 10 fractions (85%) concurrently with infusional 5‐fluorouracil (41%), gemcitabine (39%), or capecitabine (20%).RESULTS.The median follow‐up was 5.5 months (range, 1–63 months). For all patients, the median overall survival (OS) and progression‐free survival (PFS) were 9 months and 5 months, respectively, and the 2‐year estimated OS and PFS rates were 9% and 5%, respectively. The median OS and PFS were 8.5 months and 4.2 months, respectively, in the CR group and 11.9 months and 6.4 months, respectively, in the CCR group (both P < .001). The median times to local and distant progression were 6.0 months and 5.6 months, respectively, in the CR group and 8.9 and 9.5 months, respectively, in the CCR group (P = .003 and P = .007, respectively). There was no significant difference in the patterns of failure with the use of induction chemotherapy.CONCLUSIONS.The results from this analysis indicated that, by excluding patients with rapid distant progression, induction chemotherapy may select patients with LAPC for optimal benefit from consolidative CR. The authors believe that this strategy of enriching the population of patients who receive a locoregional treatment modality merits prospective randomized evaluation.

Birth weight and risk of cancer
Authors: Ahlgren Martin , Wohlfahrt Jan , Olsen Lina W. , Sørensen Thorkild I.A. , Melbye Mads 
Published: May 2007

AbstractBACKGROUND.It is well established that prenatal biologic processes are important for the development of some childhood cancers, whereas less is known regarding their influence on adult cancer risk. High birth weight has been associated with risk of breast cancer, whereas studies of other specific cancers and all cancers together have been less conclusive.METHODS.The authors established a cohort of more than 200,000 men and women who were born between 1936 and 1975. Birth weights were obtained from school health records and information concerning cancer from the Danish Cancer Registry. Follow‒up was performed between April 1, 1968 and December 31, 2003. During 6,975,553 person‐years of follow‒up, a total of 12,540 primary invasive cancers were diagnosed.RESULTS.Analyses of site‒specific cancers revealed that the majority of cancers had a positive linear association with birth weight. Departures from a positive linear association were found to be statistically significant for cancers of the pancreas and bladder, which demonstrated a V‒shaped association, and testicular cancer, which demonstrated an inverse association with birth weight. Excluding these 3 exceptions, the trends for the individual cancer sites were not heterogeneous, and the overall trend was a relative risk of 1.07 (95% confidence interval, 1.03–1.11) per 1000‒g increase in birth weight. This trend was the same in men and women and in all age groups.CONCLUSIONS.A 7% increase in cancer risk was observed per 1000‒g increase in birth weight. Few cancers demonstrated a nonlinear association with birth weight, and testicular cancer was found to be negatively associated with birth weight. The authors hypothesized that the biologic explanation behind the association between birth weight and cancer at different sites should be sought in a common pathway.

Neuroanatomical relations of prothoracicotropic hormone neurons with the circadian timekeeping system in the brain of larval and adult Rhodnius prolixus (Hemiptera)
Authors: Vafopoulou Xanthe , Steel Colin G.H. , Terry Katherine L. 
Published: May 2007

AbstractThis paper reports the localization in the Rhodnius prolixus brain of neurons producing the key neuropeptide that regulates insect development, prothoracicotropic hormone (PTTH) and describes intimate associations of the PTTH neurons with the brain circadian timekeeping system. Immunohistochemistry and confocal laser scanning microscopy revealed that the PTTH‐positive neurons in larvae are located in a single group in the lateral protocerebrum. Their number increases from two in the last larval instar to five during larval‐adult development. In adults, there are two distinct groups of these neurons composed of two cells each. A daily rhythm in content of PTTH‐positive material occurs in both the somata and the axons in both larval and adult stages. These rhythms correlate with previous evidence of a circadian rhythm of PTTH release from brains in vitro. The key circadian clock cells of Rhodnius are eight neurons, which co‐express pigment‐dispersing factor (PDF) and the canonical clock proteins PER and TIM; PDF fills the axons. Equivalent cells control behavioral rhythms in other insects. Double labeling revealed intimate associations between axons of larval PTTH neurons and clock neurons, indicating a neuronal pathway from the brain timekeeping system for circadian control of PTTH release. Additional PDF neurons appear in the adult, associated with the second group of PTTH neurons. These findings provide the first direct evidence that neurons of the insect brain timekeeping system control hormone rhythms. The range of functions regulated by this timekeeping system is quite similar to those of the vertebrate suprachiasmatic nucleus, for which the insect system is a valuable model. J. Comp.

Lay inferences of personality traits: The role of behaviour prototypicality and between‐trait differences
Authors: Wojciszke Bogdan , Pienkowski Ryszard , Maroszek Andrzej , Brycz Hanna , Ratajczak Marlena 
Published: May 2007

AbstractIn Study 1, 60‐item sets of behavioural acts exemplifying a personality trait were elicited for each of 40 traits. Each set of behaviours was then rated by 66 students for their inferential meaning (prototypicality) and evaluative meaning (valence). As predicted, the traits differed in the degree of congruence between the two meanings of their exemplifications. In Study 2, 80 subjects were presented with behaviour descriptions varying in their prototypicality for congruent or incongruent traits, and were asked for trait inferences and evaluations. The higher prototypicality, the more the inferred traits were similar to the original ‘criterion’ traits and the more extreme were the ascriptions of those freely inferred traits. As predicted on the basis of accentuation theory, behaviours exemplifying congruent traits led to more extreme trait inferences and evaluations than behaviours exemplifying incongruent traits. We conclude that trait inferences and evaluations are based both on prototypicality of behavioural acts and on structural properties of the traits examplified by these acts.
