Diffraction-line broadening routes are briefly reviewed. Both laboratory and synchrotron xray measurements of W and MgO showed that a Voigt function satisfactorily fits the physically broadened line profiles. The consequences of an assumed Voigt-function profile shape for both sizebroadened and strain-broadened profiles (“double-Voigt” method) are studied. It is shown that the relationship betw...

A novel and compact Er-Yb: glass laser was developed with single-frequency output power 10 mW in a wavelength range from 1531 to 1547 nm. The laser output was efficiently frequency doubled at 770.1 nm in a single-pass periodically poled lithium niobate waveguide and a second harmonic power in excess of 15 W was achieved, with an internal conversion efficiency of 220% W 1. This frequency-doubled...

this study was conducted to investigate the effects of using gracilariopsis persica in layer diet on performance, egg quality and lipids of blood serum of layer hens. one-hundred hy-line w-36 hens were allocated to five dietary treatments (experimental diets containing 0, 5, 10, 15 and 20 percent seaweed) and five replicates and four birds in each for 12 week period (23-34 week of age). the res...

this experiment was conducted to evaluate the effects of different levels of costmary(tanacetum balsamita)medicinal plant on performance, egg traits, and blood biochemical parameters of laying hens. hundred-eighty of hi-line laying hens (w 36) from 46 until 58 weeks of age were used in a completely randomized design in five treatments and three replicates (12 birds per replicate). the treatment...

to design equipment and facilities to dry, preserve and process pomegranates, it is necessary to know their specific heat and thermal conductivity. the objectives of this study were to determine the specific heat and thermal conductivity of pomegranates and develop mathematical estimation models for them. the effects of moisture content (15-75% w.b.) and temperature (5-20°c) on the thermal prop...

Recent measurements of the properties of W + W − events produced in e + e − collisions at √ s ∼ 183 GeV at LEP are reviewed. The data are used to investigate the predicted effects of final state interactions, specifically " colour reconnection ". 1 Motivation Hadronic data in e + e − collisions can be characterised by event shape distributions and inclusive observables such as charged particle ...

In this paper simulation results of a single IGBT open-circuit fault diagnostic system for a two-level voltage inverter-fed direct field-oriented controlled induction motor drive are presented. A fault diagnostic procedure is carried out by utilizing an analysis of an estimated rotor flux space vector trajectory in stationary  coordinates. In the article an original approach for a fault extr...

Let {W (t), t ≥ 0} be a standard Brownian motion. If I is a bounded interval on which W has no zero, an almost sure lower bound to inf{|W (t)|, t ∈ I} can be provided, when I is taken from a given countable family of intervals covering the positive half-line. 1 Main Result Let {W (t), t ≥ 0} be a standard Brownian motion. Let I be some bounded interval of R. Suppose W (t) 6= 0, for all t ∈ I. W...

where B(v, w) = 12(Q(v + w) − Q(v) − Q(w)) is the bilinear form associated to Q. The transformation sw is linear, fixes the plane w⊥ = {v : v ⊥ w}, and acts by negation on the line through w. These properties characterize sw. We will use reflections associated to the four vectors e1 = (1, 0, 0), e2 = (0, 1, 0), e3 = (0, 0, 1), and e1 + e2 + e3 = (1, 1, 1). The vectors e1, e2, and e3 form an ort...

Let $\mathcal{E}^3\subset TM^n$ be a smooth $3$-distribution on manifold of dimension $n$ and $\mathcal{W}\subset\mathcal{E}$ line field such that $[\mathcal{W},\mathcal{E}]\subset\mathcal{E}$. Under some orientability hypothesis, we give necessary condition for the existence plane $\mathcal{D}^2$ $\mathcal{W}\subset\mathcal{D}$ $[\mathcal{D},\mathcal{D}]=\mathcal{E}$. Moreover study case where...
