the paper presents an analysis of both energy intensity and energy demand for the italianindustrial sector. the aim of the paper is twofold: making a decomposition of energy intensity at the aggregate level and modeling energy demand at the firm level. the decomposition of energy intensity shows different patterns for the different sub-sectors in the period of interest. in the micro approach, p...

Benchmark first principles calculations of the pure rotational and ro.vibrational transition frequencies and line strengths are presented, using two independent program suites. Both sets of calculations were performed using the same potential energy and dipole surfaces. Our example calculations use recently calculated surfaces for H 2S which have been shown to give good agreement with experimen...

برهمکنش های بین مولکولی به سهم های دافعه ای برد کوتاه با شیب تند و جاذبه ای برد بلند با شیب کند تقسیم بندی می شوند. برهمکنش های برد کوتاه، هنگامی حائز اهمیت می شوند که ابرهای الکترونی دو ملکول شروع به همپوشانی می کنند سهم های برد بلند خود به سهم های الکتروستاتیک، القایی و پاشیدگی تقسیم می شوند دو نوع اول به وسیله الکتروستاتیک کلاسیکی و نوع سوم به وسیله مکانیک کوانتومی توضیح داده می شوند.

An empirical potential energy surface has been developed for the Ne·OH/D complexes from the experimentally observed vibrational and rotational energy levels with ab initio calculations being used for initial esti-

     A 28-week experiment was conducted to study the effects of dietary energy and digestible methionine level on performance and reproductive traits of broiler breeder hens, using 280 Arian broiler breeder hens and 20 males at 26 weeks of age. The experiment was done as 2×2 factorial arrangement in a completely randomized design with 4 treatments and 5 replicates. Dietary treatments were formu...

In this paper, a two-level optimization model of mixed quadratic integer programming (MIQP) is presented in order to optimally operate microgrids under worst-case output conditions of renewable energy sources. This two-level model is divided into two high-level and low-level problems. In the high-level problem, the goal is to reduce energy loss and load shedding in the demand response program, ...

In this paper, we study a power control game over a collision channel. Each player has an energy state. When choosing a higher transmission power, the chances of a successful transmission (in the presence of other interference) increases at the cost of a larger decrease in the energy state of the battery. A central feature in these games is that of the limitation on battery life. Natural questi...

The various dynamical scales below the pion mass involved in π+ π− atoms are sequentially integrated out using non-relativistic effective field theory techniques. This allows us to systematically organise the corrections to the energy levels and decay width. We present our results in terms of a single unknown constant which may be obtained by matching to the Chiral Lagrangian with electromagnet...

I t has long been a chemist’s dream to catch a chemical reaction in the act. In a chemical reaction, reactant atoms or molecules pass over energy barriers, through transition states, and eventually convert into new chemical products. Chemists would like to observe and interfere with this process in mid-course and thereby control its outcome. The development of lasers that produce pulses of ligh...
