A new type of two-color four-wave mixing spectroscopy is theoretically and experimentally demonstrated. By employing a non-resonant pumping and resonant probing scheme, OH radicals are detected in a laminar, atmospheric pressure methane/air flame as a proof-of-principle experiment. Two 532 nm laser beams from a multi-mode Nd:YAG laser are utilized to create an electrostrictive grating in the flame
In this paper. we construct a homogeneous spatio-temporal model to describe the variability of significant wave height over small regions of the sea and over short periods of time. Then. the model is extended to a non-homogeneous one that is valid over larger areas of the sea and for time periods of up to 10 h. To validate the proposed model. we reconstruct the significant wave height surface unde
A method for the observation of the three-dimensional structure of intact ectomycorrhizal rhizomorphs is described. The method is based on a combination of clearing the material with KOH followed by staining with congo red and subsequent imaging under a laser scanning confocal microscope (LSCM). The images obtained are of a much higher three-dimensional resolution than those obtained previously by
Background: This study examines Swedish young adults (age 21) with a history of conduct disorder (CD) in adolescence. Research has established CD as a condition for a range of adverse outcomes. Intelligence, aggression, parent-child conflict, parent-child relation and peer-rejection are known factors influencing the outcome. Aim: The aim of this longitudinal study is to find how self-confidence an
S-100beta promotes neurite extension in vitro and motoneuron survival in the chicken embryo. We demonstrate here that local administration of S-100beta stimulates the sciatic nerve regeneration into acellular muscle grafts. Normally there is a 8-10 day delay in the regeneration of axons into such grafts. Local administration of S-100beta (0.5-1.0 microg/h) significantly stimulated regeneration int
Effective treatment of bleeding episodes in hemophilia with high titer inhibitors (HTI) remains a challenge, despite the fact that the therapeutic armamentarium has expanded considerably over the past few years. Treatment safety has improved with the availability of porcine factor VIII (FVIII) and bypassing products such as recombinant factor VIIa (rFVIIa), and plasma-derived activated Prothrombin
gamma-Carboxyglutamic acid (Gla) is an unusual amino acid that is synthesized post-translationally from glutamate in a vitamin K-dependent reaction. The dicarboxylic side chain of Gla chelates Ca(2+), a property important for the biological activity of vitamin K-dependent proteins. To date, Gla-containing polypeptides have been identified in venom from two groups of organisms: elapid snakes, and s
Several models have been proposed in the literature for numerical simulations of pulverised wood drying, pyrolysis, gasification and combustion processes. These models are based on different assumptions and they yield fairly different results. In the present study a pulverised wood flame in a laboratory vertical furnace is chosen as the test case to evaluate the different sub-models including, dry
Introduction: The role of the exocrine pancreas in regulating gut microflora colonization is unclear. The main objective in the current study was to assess the effect of pancreatic fluid on the growth of pathogenic bacteria and fungi. Methods: The antibacterial activity of pure pig pancreatic juice collected from catheterized, healthy, conscious, and anesthetized pigs was investigated with multir
Jaws of fossil marine polychaete annelids, scolecodonts, from Sweden have chiefly been reported from Silurian strata. The specimens described in this paper come from Upper Danian (Paleocene) strata of the Limhamn quarry in Skane (Scania), the southernmost province of Sweden. The jaws are assigned to the Recent genera Glycera and Drilonereis, but their state of preservation did not allow species id
Considering an effectively attractive quasi-one-dimensional Bose-Einstein condensate of atoms confined in a toroidal trap, we find that the system undergoes a phase transition from a uniform to a localized state, as the magnitude of the coupling constant increases. Both the mean-field approximation, as well as a diagonalization scheme, are used to attack the problem.
A reaction system consisting of terephthalic acid, NaOH, inorganic Mn(II) or Mn(III) salt, and salicylidene alkylimine resulted in dinuclear manganese complexes (salpn)(2)Mn-2(mu-phth)(CH3OH)(2) (1, salpn = N,N'-1,3-propylene-bis(salicylideneiminato); phth = terephthalate dianion), (salen)(2)Mn-2(mu-phth)(CH3OH)(2) (2, salen = N,N'-ethylene-bis(salicylideneiminato)), (salen)(2)Mn-2(mu-phth)(CH3OH)
Polymerization of dimethylacrylamide (DMAAm) cross-linked with PEG diacrylate was studied using H-1 NMR both in situ in a semi frozen system and in a supercooled aqueous system. The amount of nonfrozen microphase, in which polymerization proceeds, is defined by the concentration of the starting monomers and the freezing temperature, which depends on the depression in freezing temperature caused by
In this study, the effects of the accumulation of cysteine protease inhibitors on the food preferences of adult female western flower thrips, Frankliniella occidentalis (Pergande), were investigated. Representative members of the cystatin and thyropin gene families (stefin A, cystatin C, kininogen domain 3 and equistatin) were expressed in potato (Solanum tuberosum) cv. Impala, Kondor and Line V p
For real time embedded systems software performance is one of the most important quality attributes. Controlling and predicting the software performance in software is associated with a number of challenges. One of the challenges is to tailor the established and rather general performance activities to the needs and available opportunities of a specific organization. This study presents a qualitat
Aim This study aims to investigate suicide risk factors after attempted suicide and whether and how these risk factors differ between the sexes. Method A total of 1052 suicide attempters admitted to the Medical Emergency Inpatient Unit, Lund University Hospital, Sweden were followed up concerning suicide and death from other causes after a median period of 6 years and 5 months. in all, 50 persons
