The optimal conditions for mycelial growth of Phellinus linteus ATCC 26710 were determined to be a log length of 20 cm, temperature of 30℃ and pH of 6.0. Mycelial growth was excellent on the mushroom complete medium, and was optimal when sucrose, mannose and glucose were supplied as carbon sources. Potassium nitrate and sodium nitrate as nitrogen sources supported good mycelial growth. To evalu...

Proper determination of bed boundaries in layered reservoirs is vital ‎for accurate petrophysical interpretation of conventional logs. In the ‎wellbore, logs continuously measure physical properties of reservoir ‎while the properties change stepwise. This continuous representation ‎of logs may lead to ignorance of some high potential reservoir zones. ‎The main reasons for continuous nature of l...

The European woodwasp, Sirex noctilio F., is a pest of pines in many areas around the world. Since its introduction to North America, the distribution of S. noctilio overlaps with a known host (Pinus sylvestris) and hosts native to North America. Direct comparisons of suitability for oviposition and larval survival among these pines have not been made. We tested the relative suitability of four...

The diiculty in solving the discrete logarithm problem is of extreme cryptographic importance since it is widely used in signature schemes, message encryption, key exchange, authentication and so on ((15], 17], 21], 29] etc.). The General Number Field Sieve (GNFS) is the asymptotically fastest known method to compute discrete logs mod p 18]. With the rst implementation of the GNFS for discrete ...

A three-stage V-band amplifier implemented in 65-nm baseline CMOS technology is presented in this paper. Slow-wave coplanar waveguides are used for matching and interconnects to study the benefits of using this line type in amplifier design. Measured power gain, noise figure and 1 dB output compression point at 60 GHz are 13 dB, 6.3 dB and ?4 dBm, respectively. The amplifier has 19.6 GHz of 3 d...

We present, in this paper, a detailed translation from algorithms implemented on a standard model of parallel computation — the CREW PRAM — to DNA-based methods. Our translation is efficient in the following sense: if A is a PRAM algorithm using P (n) processors, S (n) space, and taking T (n) time then the total volume of DNA used is O ( P (n) T (n) S (n) logS (n) ); furthermore, the total comp...

An important method in oil and gas exploration is vertical seismic profile (VSP) to estimate rock properties in drilling well. Quality factor is also the crucial point of seismic attenuate in VSP data. In the present study, this factor was used to evaluate the hydrocarbon potential of Kangan Formation in one of the Persian Gulf oil fields using VSP zero offset method. Quality factor was estimat...
