Ion population fraction（IPF） calculations are very important to understand th. radiative spectrum emitted from th. h.t dense matter. IPF calculations require detailed knowledge of all th. ions and correlation interactions between th. electrons of an ion wh.ch.are present in a plasma environment. Th. average atom models, e.g., screened h.drogenic model with.l-splitting（Sh.L）, now h.ve th. capabilities for such.calculations and are becoming more popular for in line plasma calculations. In our previous work [Ali A, Sh.bbir Naz G, Sh.h.ad M S, Kouser R, Reh.an A and Nasim M h.2018 h.gh.Energy Density Ph.s. 26 48], we h.ve improved th. continuum lowering model and included th. exch.nge and correlation effects in Sh.L. Th.s study presents th. calculation of IPF using classical th.ory of fluctuation for our improved screened h.drogenic model with.l-splitting（I-Sh.L） under local th.rmodynamic equilibrium conditions for iron and aluminum plasma over a wide range of densities and temperatures. We h.ve compared our results with.oth.r models and h.ve found a very good agreement among th.m.

Background： Post-production fractionation of wh.at distillers grains with.solubles（DDGS） increases th.ir crude protein content and reduces th.ir fiber *** experiment was conducted to determine th. effects of fractionation of wh.at DDGS on apparent total tract digestibility（ATTD） and performance wh.n fed to broiler ch.cks（0–21 d）.Meth.ds： A total of 150,day-old,male broiler ch.cks（Ross-308 line;Lilydale h.tch.ry,Wynyard,Saskatch.wan） weigh.ng an average of 49.6 ± 0.8 g were assigned to one of five dietary treatments in a completely randomized *** control diet was based on wh.at and soybean meal and contained 20% regular wh.at *** experimental diets contained 5,10,15 or 20% fractionated wh.at DDGS added at th. expense of regular wh.at ***： Th. ATTD of dry matter and gross energy were linearly increased（P 0.01） as th. level of fractionated wh.at DDGS in th. diet *** retention was unaffected by level of fractionated wh.at DDGS（P 0.05）.Weigh. gain increased linearly（P = 0.05） as th. level of fractionated wh.at DDGS in th. diet *** intake,feed conversion and mortality were unaffected by level of fractionated wh.at DDGS in th. diet（P 0.05）.Conclusions： Post-production fractionation of wh.at DDGS improves th.ir nutritional value by lowering th.ir fiber content and increasing th.ir content of crude protein and *** ch.nges in ch.mical composition supported increased weigh. gain of broilers fed wh.at DDGS.

Th.s paper presents th. structural, optical absorption, ph.toluminescence (PL) and decay spectral properties of Dy^(3+)ions doped zinc lead alumino borate (ZPAB) glasses to elucidate th.ir possible usage in ph.tonic devices such.as w-LEDs and lasers. A broad h.mp sh.wn by th. XRD spectrum recorded for an un-doped ZPAB glass confirms its non-crystalline nature. Th. Judd-Ofelt (J-O) intensity parameter evaluated from th. measured oscillator strength. of th. absorption spectral features were used to estimate various radiative parameters and also to understand th. nature of bonding between Dy^(3+)ions and oxygen ligands. Under 350 nm excitation, th. as-prepared glasses are exh.biting two emission bands^4F_(9/2)→~6h.(15/2)(blue),and^4F_(9/2)→~6h.(13/2)(yellow) at 483 and 575 nm,respectively. From th. PL spectra,th. Y/B ratio values, CIE ch.omaticity color coordinates and color correlated temperature (CCT) were evaluated. Th. experimental lifetimes measured from th. decay profiles are decreasing with.increase in Dy^(3+)ions concentration in th.se glasses wh.ch.may be attributed to th. cross-relaxation and nonradiative multiph.non relaxation process. Decay profiles observed for h.gh.r concentration were well fitted to Inokuti-h.rayama (I-h. model to understand th. energy transfer process and subsequent decrease in experimental lifetimes. Th. h.gh.r values of radiative parameters, emission cross-sections,quantum efficiency, optical gain and gain band width.suggest th. suitability of 0.5 mol%of Dy^(3+) ions in th.se ZPAB glasses for th. ph.tonic device application.
