In this paper, we use resource-bounded dimension theory to investigate polynomial size circuits. We show that for every i ≥ 0, P/poly has ith order scaled p 3 -strong dimension 0. We also show that P/poly i.o. has p 3 -dimension 1/2, p 3 -strong dimension 1. Our results improve previous measure results of Lutz (1992) and dimension results of Hitchcock and Vinodchandran (2004).

background: drug nano-carriers are one of the most important tools for targeted cancer therapy so that undesired side effects of chemotherapy drugs are minimized. in this area, the use of ultrasound can be helpful in controlling drug release from nanoparticles to achieve higher treatment efficiency. objective: here, we studies the effects of ultrasound irradiation on the release profile of 5-fl...

this study was designed to assess the role of first-line chemotherapy with 5-fu and platinum in the treatment of advanced or recurrent cervical cancer, ten patients with advanced or recurrent cancer of the cervix, with no prior chemotherapy were entered in phase ii trial, from oct. 2000 to nov. 2001. eight patients were treated with cis-platinum (50 mg/m2 over 60 minutes in first day) followed ...

background and objectivesintercropping or simultaneous growing of two or more crops on the same piece of land has the potential of enhanced ecosystem productivity. in a cereal-legume intercropping system, an increase in cereal and a decrease in legume intercrop yield is reported. several indices such as land equivalent ratio (ler), relative crowding coefficient (k), competitive ratio (cr), aggr...

drought is the most common environmental stresses that affects plant growth. to study the combined effects of arbuscular mycorrhizal fungi (glomus intratadices) and jasmonic acid on growth and ecophysiologycal characteristics of pistachio seedlings cv. qazvini under drought stress, a greenhouse experiment was conducted in a completely randomized design with three replications. experimental fact...

polyacrylonitril (pan)-supported chitosan (cs) nanocomposite membranes were prepared by cross-linking the cs with 3-aminopropyl-triethoxysilane (apteos) via sol-gel method. pervaporative performances of the cs-sio2/pan membrane for dehydration of aqueous alcohol solutions were investigated. from sem cross-sectional images of the membrane, the spongy pores and the finger-like pores were found in...

in this study, energy consumption pattern, efficiency and the percentage of saved energy and inputs of poultry production farms in isfahan, nain and najafabad townships with different capacities were evaluated. the average of net energy gain per 1000 bird for capacities less than 10, 10-30 and more than 30 thousand pieces was calculated as -143.66, -129.58 and -94.99 gj/1000 bird, respectively....

ziziphora tenuior, named kakooti in farsi, is one of the aromatic and medicinal plants of a wide distribution in iran. in this study, rapd molecular markers, (by utilization of 16 primers) was applied to determine the genetic diversity of 39 samples of ziziphora tenuior from 21 geographical regions in iran. a number of 100 polymorphic bands out of 110 amplified ones was produced and analyzed th...

two simple visible spectrophotometric methods are developed and validated for the quantification of modafinil using 1,2-naphthoquinone-4-sulphonic acid (nqs method) and 2,4-dinitrophenol (dnp method) as analytical reagents. the nqs method involves the reaction of modafinil with 1,2-naphthoquinone-4-sulphonate in alkaline medium at room conditions to form a yellow colored product exhibiting maxi...
