چکیده
ABSTRACT A scheme for systematically separating ultraviolet divergences of Feynrnan amplitudes in parametric space is developed. It is summarized by an explicit formula which enables us to incorporate readily the ultraviolet-finite remainders thus constructed into the usual renormalization s theme . It is shown further that infrared divergences can be treated in a very similar way. Our method is particularly suitable for numerical -. integration.

Photocatalytic degradation of rhodamine B, and phenol red dyes using NiMn2O4 nanoparticles prepared by a new approach
NiMn2O4 nanoparticles have been successfully prepared through sol-gel method. The effects of different factors such as the type of solvent, and amino acid temperature were investigated on the size and morphologies of products. The smallest particle size of NiMn2O4 nanoparticles was found to be 25 nm in diameter. The magnetic properties of the samples were also measured by an alternating gradien...
متن کاملA New School Bus Routing Problem Considering Gender Separation, Special Students and Mix Loading: A Genetic Algorithm Approach
In developing countries, whereas the urban bus network is a major part of public transportation system, it is necessary to try to find the best design and routing for bus network. Optimum design of school bus routes is very important. Non-optimal solutions for this problem may increase traveling time, fuel consumption, and depreciation rate of the fleet. A new bus routing problem is presented i...
متن کاملNew Legionella Control Options by UV and Violet LEDs for Hospitals and Care Facilities
Legionella infections caused by contaminated water are a widespread problem worldwide. Discharge lamps like mercury vapor lamps are widely known for the disinfection properties of their radiation, but they suffer technical disadvantages, like high voltages and toxic content, and are, therefore, not suitable for some infection control applications. New high-intensity ultraviolet (UV) an...
متن کاملDetermination of mirtazapine and desmethyl mirtazapine in human plasma by a new validated HPLC ultraviolet method with a simple and reliable extraction method: Application to therapeutic drug monitoring study by 62 real patient plasma
Determination of mirtazapine during psychopharmacotherapy in biological fluids is essential to achieve successful therapy, to avoid toxicity related to drug interactions, genetic variability and poor compliance. A new, rapid and sensitive high-performance liquid chromatography method has been developed in human plasma for the determination of mirtazapine (MRP) and N-desmethylmirtazapine (NDM) t...
