SW-163A and B, novel immunosuppressants, were isolated from the culture broth of Streptomyces sp. SNA15896. The molecular formulas of SW-163A and B were determined as C34H42N2O12 and C33H40N2O12 based on the HRFAB-MS analysis, respectively. Both compounds were elucidated to be a large ring ester structure through spectroscopic analyses including various NMR measurements. SW-163A and B showed im...

We report spontaneous parametric downconversion having an unusually wide spectral bandwidth. A collinear type-1 phase-matching configuration is employed with degeneracy near the zero group velocity dispersion frequency. With a spectral width of 1080 nm and degenerate wavelength 1885 nm, the source also emits a high flux of 3.4×10 sW photon pairs constrained to a cone of only ≈2◦ half-angle. A r...

chemical and morphological characterization of different parts of banana plant(musa paradisica) (peduncle, leaf stalk and pseudo stem) were carried out in orderto assess their potentiality for chemical pulp. each portion was tested forextractives, sodium hydroxide solubility, ash, lignin, cellulose and pentosancontents as well as their fiber length and width. these segmented parts werecharacter...

Midday depressions in stomatal conductance (g(s) ) and photosynthesis are common in plants. The aim of this study was to understand the hydraulic determinants of midday g(s) , the coordination between leaf and stem hydraulics and whether regulation of midday g(s) differed between deciduous and evergreen broadleaf tree species in a subtropical cloud forest of Southwest (SW) China. We investigat...

rice sheath blight disease caused by rhizoctonia solani ag1- ia is the secondeconomically important disease of the crop in most rice- growing regions of the world,including northern of iran. the disease is mainly controlled through application of fungicides.the present study was performed to identify the candidate cultivar (cultivars) as source ofresistance to the pathogen in rice field conditi...

Poisson regression and negative binomial regression have been widely used to model the road crashes and to predict crash frequency. Zero inflated models have been shown to be a powerful tool to predict crash frequency when crash data are characterized by preponderance of zero. This paper presents the research work aiming to correlate the road traffic crash rate with road geometry and traffic ch...

One hundred and ninety two records were taken weekly for twenty four (24) weeks from West African Dwarf (WD), the Yankasa (YN) X crossbred (XB) sheep. The traits evaluated milk yield (MK), linear body measurements (LB) such as height at withers, (HT), length (BL), heart girth (HG), shoulder width (SW), Tail (TA), Neck (NL), circumference (NC), Face (FA), Hind leg (HL), Foreleg (FL), Ear (EA), H...

Coupling experiments at small spatial scales with large-scale surveys can help to generalize experimental results across large spatial scales. The goal of the present study was to evaluate patterns of crab herbivory within and, at a larger scale, between many southwestern (SW) Atlantic salt marshes. Hence, we conducted experiments in an Argentinean salt marsh to elucidate the effects of crab Ch...
