در پژوهش حاضر از نرمافزار HYDRUS-2D/3D برای برآورد پارامترهای هیدرولیکی مدل ونگنوختن-معلم در سه بافت متفاوت خاک به روش معکوس، با استفاده از دادههای نفوذسنج استوانههای دوگانه، استفاده شد. برای این منظور نه گزینه با تعداد متفاوت پارامترهای هیدرولیکی انتخابشده برای فرایند بهینهسازی (5، 4 و 3 پارامتر)، در سه گروه مجزا تعریف شد. در گروه اول تنها از دادههای نفوذ تجمعی اندازهگیریشده به عنوان ...
پارامتر های جدول زندگی کفشدوزک serangium montazerii fursch (coleoptera: coccinellidae) روی دو میزبان گیاهی نارنگی پیج ((citrus sp.([citrus paradisi×c. reticulate]×c. clementinaو پرتقال تامسون ناول (citrus sinensiscv. thompson)، در شرایط آزمایشگاهی (1±25 درجه سانتی گراد و رطوبت نسبی 5±65 درصد و دوره روشنایی : تاریکی 16:8 ساعت) بررسی شد. دوره پیش از تخمریزی کل این کفشدوزک روی نارنگی پیج و پرتقال ...
BACKGROUND The usefulness of estimated glomerular filtration rate (eGFR) and albuminuria for prediction of cardiovascular outcomes is controversial. We aimed to assess the addition of creatinine-based eGFR and albuminuria to traditional risk factors for prediction of cardiovascular risk with a meta-analytic approach. METHODS We meta-analysed individual-level data for 637 315 individuals witho...
STUDY OBJECTIVE These experiments were designed to examine the effect of manipulation during surgery as a cofactor in adhesion formation at trauma sites. DESIGN Randomized, controlled trial. Canadian Task Force Classification-class 1. SETTING University laboratory research center. SUBJECTS A standardized laparoscopic mouse model (Balb\c mice 9-10 weeks old) for adhesion formation after op...
We study 16,707 quasar spectra from the Sloan Digital Sky Survey (SDSS) (an early version of the First Data Release; DR1) using the Karhunen-Loève (KL) transform (or Principal Component Analysis, PCA). The redshifts of these quasars range from 0.08 to 5.41, the i-band absolute magnitudes from −30 to −22, and the resulting restframe wavelengths from 900 Å to 8000 Å. The quasar eigenspectra of th...
Here we present the New York University Value-Added Galaxy Catalog (NYU-VAGC), a catalog of local galaxies (mostly below z ≈ 0.3) based on a set of publicly-released surveys matched to the Sloan Digital Sky Survey (SDSS) Data Release 2. The photometric catalog consists of 693,319 galaxies, QSOs and stars; 343,568 of these have redshift determinations, mostly from the SDSS. Excluding areas maske...
BACKGROUND In contrast to studies showing gradual adaptation of melatonin (MT) rhythms to an advanced photoperiod in humans and rodents, we previously demonstrated that equine MT rhythms complete a 6-h light/dark (LD) phase advance on the first post-shift day. This suggested the possibility that melatonin secretion in the horse may be more strongly light-driven as opposed to endogenously rhythm...
Dueto theactionofo-quinones formedviapolyphenoloxidase, conserved red clover (Trifolium pratense L.) contains abundant rumen undegradable protein (RUP), but inadequate rumen degradable protein (RDP) fordairy cattle. This studyexaminedhowforagemanagement influences RDP, RUP, crude protein (CP) and fiber fractions in red clover silage and dry matter (DM) yields during the first full production ye...
We study the evolution of the ionization state of the intergalactic medium (IGM) at the end of the reionization epoch using moderate resolution spectra of a sample of nineteen quasars at 5.74 < zem < 6.42 discovered in the Sloan Digital Sky Survey. Three methods are used to trace IGM properties: (a) the evolution of the Gunn-Peterson (GP) optical depth in the Lyα, β, and γ transitions; (b) the ...
