Background: Little is known about Giberellic acid, a plant growth regulator used in many countries, on sperm parameters; so this study was conducted to evaluate its effects on sperm parameters. Materials and Methods: A number of twenty seven adult rats were divided into three groups (n=9): control group (C), control-sham group (C-Sh) and treatment group (Tr). The C-Shgroupand the Tr group were ...

Source rocks from a marine depositional setting from Palaeozoic formations in the Holy Cross Mountains region (Midlands, Poland) were analysed for aromatics using capillary gas chromatography±mass spectrometry (GC±MS). The occurrence of two novel series of aromatic hydrocarbons in these sediments, namely phenyl derivatives of fused ring polycyclic aromatic hydrocarbons (PhPAH) and polyphenyls (...

in order to evaluate plant density and cultivar effects on rate and process of grain filling, yield and yield components of three dry bean cultivars a factorial experiment (using r.c.b. design) was conducted in 1386 at agricultural and natural research center of east azarbaijan (tabriz). three cultivars (khomeyn, g-14088 and 11816) were planted at four densities (14, 20, 30 and 60 plants/m2) in...

Numerous and diverse physiological changes occur during fruit ripening and maturity at harvest is one of the key factors influencing the flavour quality of fruits. The effect of ripening on chemical composition, physical parameters and sensory perception of three muskmelon (Cucumis melo L. reticulatus group) cultivars was evaluated. Significant correlations emerging from this extensive data set...

We provide a full characterisation of the large-maturity forward implied volatility smile in the Heston model. Although the leading decay is provided by a fairly classical large deviations behaviour, the algebraic expansion providing the higher-order terms highly depends on the parameters, and different powers of the maturity come into play. As a by-product of the analysis we provide new implie...

conclusions the produced compost in this study was mature and ready for use as an agricultural substrate or soil conditioner after 80 days of composting. results the results showed that the c/n ratio decreased during the composting process (reached to 15.6) due to the loss of carbon and the increase in nitrogen content per unit material; also, the nh4+/no3 ratio decreased with increase in the t...

This document evaluates the Propagation Rule Compiler (PROP) which has been developed at the Univ. of Bonn and continuously improved within the last three years. The purpose of PROP is to analyze all deductive rules of a given Chimera schema implementing derived concepts (attributes, classes, views, and constraints). Based on this analysis it generates triggers which are able to compute all imp...
