Preliminary information on the effectiveness of trimethacarb as a bird repellent on broadcast seed and ripening crops was obtained during 1982 and 1983 from studies in Haiti, India, the Philippines, Bangladesh, Mali, and the United States. R50 and LD50 determinations for nine pest bird species to cereal crops in these countries indicated birds were not as sensitive to trimethacarb as to the avi...

We present a relatively simple method to estimate tropical cyclone (TC) surface wind structure (34-, 50-, and 64-kt radii) intensity [maximum speed (MWS)] from fields acquired the L-band SMAP radiometer C-band Sentinel-1A/B RADARSAT-2 synthetic aperture radar (SAR) between 2015 2020. The SAR-derived radii MWS are systematically compared with best-track estimates. root-mean-square errors (RMSEs)...

More and more applications, such as natural gas liquefaction, LNG reliquefaction, whole body cryotherapy cryopreservation, require cooling in the temperature range from 110 to 150 K. This can be achieved systems using standard refrigeration compressors, which are reliable cost-effective, but subject certain operating limits. paper investigates potential of a three-stage cascaded system based on...

Mainstream object detectors are commonly constituted of two sub-tasks, including classification and regression tasks, implemented by parallel heads. This classic design paradigm inevitably leads to inconsistent spatial distributions between score localization quality (IOU). Therefore, this paper alleviates misalignment in the view knowledge distillation. First, we observe that massive teacher a...

ABSTRACT Nearby galaxies provide populations of stellar and non-stellar sources at a common distance in quantifiable environments. All are observed through the Milky Way foreground, with varying degrees contamination that depend on Galactic latitude size target galaxy. This work uses Gaia Data Release 3 (DR3) to identify foreground via astrometric measurements thus quantify for large sample nea...

To evaluate the safety and efficacy of Ex-PRESS (R50) implantation combined with phacoemulsification in primary angle-closure glaucoma (PACG) patients with cataract.Twenty-four eyes of 24 patients with unregulated PACG underwent combined cataract and glaucoma surgery. After phacoemulsification and intraocular lens implantation, the Ex-PRESS (R-50) was inserted into the anterior chamber under a ...

This article is devoted to some inverse problems arising in the context of linear elasticity, namely the identification of distributions of elastic moduli, model parameters, or buried objects such as cracks. These inverse problems are considered mainly for threedimensional elastic media under equilibrium or dynamical conditions, and also for thin elastic plates. The main goal is to overview som...

در اثر افزایش بار محوری و سرعت حرکت قطارها، چرخ قطار در طول سرویس کاری خود تحت بارهای مکانیکی و حرارتی شدیدی قرار می گیرد. بارهای مکانیکی شامل بار عمودی به سبب وزن واگن و بار عرضی به علت اختلالات خطوط راه آهن می باشند. بارهای حرارتی از تبدیل توان اصطکاکی چرخ به حرارت در طول ترمزگیری ایجاد می شوند. در این پروژه تماس چرخ منوبلوک با قطر 920 میلیمتر با پروفیل s1002 و ریل uic60 با در نظر گرفتن بار ع...
