Within the kt-factorization framework, we study diffractive production of orbitally excited vector mesons and compare it with the production of radial excitations, focusing on the ρ(1450)/ρ(1700) case. At small Q2, orbital excitation of light quarkonia is found to dominate over radial excitations in diffractive production. We predict strong suppression of the production of orbital excitations by longitudinal photons, which leads to very small σL/σT ratio. At small Q2, the s-channel helicity violating transitions contribute not, vert, similar10–15% of the transverse cross section and not, vert, similar50% of the longitudinal cross section. We also study mixing between radial and orbital excitations and determine strategies towards clarification of S-wave/D-wave assignment to ρ(1450) and ρ(1700) mesons. The results are compared with the experimental data available, and predictions for future experiments are given. [less ▲]

In this study, supercritical CO2 is successfully used as foaming agent to prepare poly(styrene-co-acrylonitrile) (SAN) foams containing a low amount of well-dispersed nanoclay (5wt%). This kind of nanofiller has an influence both on material cellular morphology and fire property. In fact, SAN foam filled with nanoclay has smaller cells and higher density compared to unfilled foam. Moreover, the nanocomposite foam burns more slowly and without producing any burning droplets, which is highly desirable when considering housing applications. [less ▲]

The capability of neonates to achieve cytokine balance was evaluated. Production of the pro-inflammatory cytokines TNF alpha and IL-8, of the natural anti-inflammatory cytokine IL10 and of the regulator of the acute phase response IL6 was assessed after whole blood stimulation by lipopolysaccharide in cord blood (n = 10), adult volunteers serving as control (n = 17). Additionally, circulating cytokines were determined in cord and in maternal blood immediately after delivery (n = 27, respectively). Significant production of TNF alpha, IL8, IL10 and IL6 was observed in cord blood after lipopolysaccharide stimulation and was similar to cytokine production in adult blood. The plasma concentrations of TNF alpha were significantly higher in cord than in maternal blood, while plasma concentrations of IL10 and IL6 were significantly lower. Our results demonstrate fully developed capability of whole cord blood to synthesize pro- and anti-inflammatory cytokines in response to a pro-inflammatory stimulation in vitro. In vivo, however, higher circulating TNF alpha and lower IL10 and IL6 levels in cord blood suggest that the inflammatory stress associated with normal delivery does not induce detectable anti-inflammatory response in neonates at birth.

OBJECTIVE: Neonates undergoing cardiac surgery have a systemic inflammatory reaction with release of proinflammatory cytokines, which could be responsible for myocardial dysfunction as a result of myocardial cell damage. The purpose of this study was to test the hypothesis that the production of proinflammatory cytokines during cardiac surgery would be associated with myocardial dysfunction after the arterial switch operation in neonates. METHODS: A total of 63 neonates with transposition of the great arteries were operated on with combined deep hypothermic circulatory arrest and low-flow cardiopulmonary bypass at a median age of 7 days. Perioperative plasma concentrations of interleukins 6 and 8 were correlated with myocardial dysfunction, as assessed clinically and by echocardiography within 24 hours after the operation, and with perioperative cardiac troponin T blood levels as a marker of myocardial cell damage. RESULTS: Myocardial dysfunction was observed in 11 patients (17.5%), and 2 of them died. Durations of cardiopulmonary bypass and aortic crossclamping, but not of circulatory arrest, were correlated with myocardial dysfunction. Patients with myocardial dysfunction had significantly higher cardiac troponin T blood levels at the end of cardiopulmonary bypass and 4 and 24 hours after the operation than did patients without myocardial dysfunction. Patients with myocardial dysfunction also had higher interleukin 6 plasma concentrations after cardiopulmonary bypass and 4 hours after the operation, as well as higher interleukin 8 plasma concentrations 4 and 24 hours after the operation, than did those without myocardial dysfunction. Postoperative interleukin 6 and 8 plasma concentrations were significantly correlated with postoperative cardiac troponin T blood levels. Multivariable analysis of independent risk factors for myocardial dysfunction comprising cytokine and troponin levels and bypass duration revealed interleukin 6 levels 4 hours after the operation as significant (P =.047). CONCLUSIONS: Cardiac operations in neonates stimulate the production of proinflammatory cytokines, which may contribute to myocardial cell damage and myocardial dysfunction. [less ▲]

Biological sulfate reduction was investigated at the bench and pilot scales in order to determine optimum culture conditions. Efficient strains of sulfate-reducing bacteria (SRB) were selected by classical microbiological methods and by mutagenesis. Improvement factors, including stripping, scale-up, sulfate,and organic substrate concentrations, have been studied in batch bioreactors. Two types of pilot-scale bioreactors have been adopted, the first being completely mixed with free cells and the second having two stages with immobilized cells on a fixed bed. An overall bioconversion capacity of 11 kg/m(3) . d of gypsum and 1.2 kg/m(3) . d of dissolved organic carbon has been achieved in the two-stage bioreactor. [less ▲]

In the production of sulfuric acid by (a) oxidizing a sulfurous material with an oxidant to obtain sulfur dioxide, (b) catalytically oxidizing this with oxygen to obtain sulfur trioxide and (c) producing sulfuric acid and a waste gas, at least part of the waste gas is recycled to the first step. The fabrication of sulfuric acid consists of: (a) producing sulfur dioxide from a sulfur based material and an oxidant; (b) converting catalytically the sulfur dioxide into trioxide in a catalytic converter fed with oxygen; and (c) producing sulfuric acid from the sulfur trioxide. In the last step, some other gases are also produced which are (partially) recycled into the oxidant used in step (a). An Independent claim is also included for apparatus for performing the process. The apparatus for H2SO4 production consists of: (a) production unit (10') of SO2 from a sulfurous raw material and an oxidant; (b) catalytic converter (20') of SO2 equipped with means of feeding O2; and (c) preparation unit (30') of H2SO4 from SO3 It comprises also means for recycling waste gases at the outlet of the preparation unit (30') of H2SO4 towards the SO2 production unit (10').
