Aims. We present the results of a search for the negative ion C4H in various dark clouds, low mass star-forming regions and photondominated regions (PDRs). We have also searched for C6H, C2H and CN in some of the sources. Methods. The millimeter-wave observations were carried out with the IRAM-30m telescope. Results. We detect C4H, through the J = 9-8 and J = 10-9 rotational transitions, in the...

By using a monoclonal antibody we have identified a new polypeptide doublet (C4h and C4l) of Mr approximately 21 kD and pI 8 and 7, respectively, that is associated with and (at the immunofluorescence level) uniformly distributed on actin filament bundles in rat, mouse, and other vertebrate species. C4 is absent in neurones, erythrocytes, and skeletal muscle but the epitope is evolutionarily co...

High resolution photodetachment spectra of C4H- and C4D- obtained via slow electron velocity-map imaging (SEVI) are presented. The spectra reveal closely spaced transitions to the neutral 2Sigma+ and 2Pi states which can be distinguished based on the corresponding photoelectron angular distributions. The C4H ground state is confirmed as the X2Sigma+ state, with the excited A2Pi state lying only...

Background & Aim: Elaeagnus angustifolia and Elaeagnus orientalis have a lot of medical utilization. In folk medicine, the fruit and flower of these plants are used as a tonic and antipyretic agent. The aim of the present study was to chemical analysis of volatile constituents of E. angustifolia and E. orientalis flowers.  Experimental: The...

Cinnamate-based polyesters were synthesized, including poly(4-hydroxycinnamic acid), poly(4-hydroxy-3-methoxycinnamic poly(3-hydroxycinnamic acid) (P3HCA), and hyperbranched poly(3,4-dihydroxycinnamic (PdHCA). These materials further processed into hard dry membranes by casting underwent photoreactions ultraviolet (UV) light. The photodeformation behavior of the linear polyester containing with...

BACKGROUND Pattern Triggered Immunity (PTI) or Basal Resistance (BR) is a potent, symptomless form of plant resistance. Upon inoculation of a plant with non-pathogens or pathogenicity-mutant bacteria, the induced PTI will prevent bacterial proliferation. Developed PTI is also able to protect the plant from disease or HR (Hypersensitive Response) after a challenging infection with pathogenic bac...

3.1 Chapter Summary A novel methodology for in situ crosslinking of polymeric fibers during electrospinning is described. The electrospinning apparatus was modified to facilitate UV irradiation of the electrospun fibers while in flight to the collector target. Three copolymers with different mol% of the photoreactive cinnamate functional group (4, 9 and 13 mol% respectively) were synthesized an...
