Environment-friendly pigments based on AFeO_(3)(A=La,Pr,Nd,Sm,Gd,Tb,Y or Yb)with high nearinfrared(NIR)reflectance were synthesised by a coprecipitation method at 1200℃.The Rietveld refinement analysis showed single-phase orthorhombic perovskite for all *** pigments,which showed reddish hues,offered good colour stability after mixing these pigments in powder form with siloxane transparent paint and two different *** powderepaint mixtures produced with GdFeO_(3),TbFeO_(3) and YFeO_(3) pigments have the highest NIR solar reflectance,reaching values of R=50%.The temperature shielding studies conducted using TbFeO_(3) pigmentepaint mixture for a roof coating yielded a reduction of 3.2℃ in comparison to a commercial ***,the glazes that were pigmented using GdFeO_(3),TbFeO_(3) and YFeO_(3) compositions also presented the most intense reddish colours.A study of the thermal and chemical stability of the pigment with the highest NIR solar reflectance showed good stability in both *** reddish pigments that were prepared can therefore be good candidates for use in different applications such as cool pigments or pigments for ceramic glazes at high temperatures.

＜正＞ Solar cells were prepared with absorber layers grown below 600℃on both polycrystalline Si seed layers on glass and Si（100） wafers. The seed layers were formed by the aluminum-induced layer exchange process （ALILE） based on the aluminum-induced crystallization of amorphous Si. To form a p-type absorber layer （～2μm） the seed layers were thickened by ECRCVD using silane and diborane. A thin, highly phosphorous-doped amorphous emitter layer was deposited. We discuss the influence of absorber layer post-treatments on the solar cell parameters. We achieved open-circuit voltages of up to 378mV for solar cells on seed layers by the application of defect annealing and hydrogen passivation. On highly-doped, p-type CZ-Si（100） we obtained an open-circuit voltage of 458mV even without any additional treatments of the absorber layer. These results are very encouraging for low-temperature preparation of solar cells.

Research findings for supplementing boar stud diets with fish oils are inconsistent. This study was designed to address three possible causes of performance variation of boars to fish oil supplementation: stability of the fatty acid source, level of inclusion and breed of boars tested. Three groups of 87 boars each, from two genetic lines (PIC 337 and PIC 800), were assigned to treatment based on age, mean sperm production (previous 12 weeks), and body condition score. All boars received a corn-soybean meal diet with a commercial fish oil supplement providing 1.83 g/boar/day of docosahexaenoic acid (DHA) as a preconditioning diet. On 10-Aug., 2020, the DHA source was changed to a stabilized starch imbedded source of refined fish oil (Salmate®), providing 1.83 g/b/d for the test diet. Two additional levels providing 2.38 and 2.94 g/b/d of DHA were fed for a 9 week pretreatment period and during the test period. Salmate® fed at 2.38 g/b/d of DHA resulted in a reduction in the number of rejected ejaculates (P 0.045) by 7.5% and 6.4% compared to the lowest and highest inclusion rates, respectively. There were no treatments by genetic line interactions. A retrospective study of semen production and quality of 77 boars on the Salmate® diet containing 1.83

The bluestem gall midge (Stenodiplosis wattsii Gagné) is native to the grasslands of North America. It feeds on the developing seeds of warm-season grasses during a portion of its lifecycle, but little is known of the biology and extent of gall midge infestations in native warm-season grasses in the USA. We investigated the infestations of the bluestem gall midge in big bluestem (Andropogon gerardii Vitman), sand bluestem (Andropogon gerardii var paucipilus), little bluestem [Schizachyrium scoparium (Michx.) Nash], and indiangrass [Sorghastrum nutans (L.) Nash] commercial seed production fields during 2001 through 2004. Our objectives were to determine the annual production cycle of the bluestem gall midge, the range of the infestation in Nebraska, and estimate its impact on seed production. In eastern Nebraska, the midge goes through four generations with the fourth entering a larval diapause, overwintering in seeds and emerging in mid-June of the following year. The bluestem gall midge damaged from 31% of the little bluestem seed to 67% of the big bluestem seed, and, on average, reduced the production of viable seed by 54% across the four grass species in eastern Nebraska. Additionally, the warm-season prairie grasses were surveyed in nine other counties in Nebraska and the bluestem gall midge was found in each species surveyed from all nine counties. This study is the first to document the negative effects of the bluestem gall midge on the production of viable seed in sand bluestem and indiangrass.
