This article discussed air quality changes in the Beijing-Tianjin-Tangshan (BTT) region. The index (AQI) values, and concentrations of PM2.5, PM10, SO2, CO, NO2, O3 BTT region during COVID-19 outbreak 2020 were, respectively, 79.4, 47.2 ?g m-3, 73.4 10.3 0.87 mg 33.6 90.7 m-3. However, they 102.7, 61.4 121.0 9.0 0.88 40.1 84.0 m-3 same period 2021, which is an increase 29.2%, 30.1%, 64.8%, -12....
در این مقاله روش غیرخطی کنترل کننده مد لغزشی موجکی با لایه مرزی تطبیقی از طریق تابع لغزشی متغیر با زمان در خودخلبان پیچشی برای موشک EMRAAT که قابلیت هدایت با مانور BTT را دارد، به کارکرفته میشود.سطح لغزشی متغیر با زمان همه فرکانسهای مدل نشده سیستم را فیلتر میکند. پهنای لایه مرزی، پهنای باند شکست فرکانس و پارامترهایی که در تقریب شبکه موجکی عصبی پدید میآیند همگی قابل تنطیم هستند. از اینرو م...
The purpose of this study was to determine the influence of starting strategy on time trial performance in the heat. Eleven endurance trained male cyclists (30+/-5 years, 79.5+/-4.6 kg, VO(2max) 58.5+/-5.0 ml x kg x (-1) min(-1)) performed four 20-km time trials in the heat (32.7+/-0.7 degrees C and 55% relative humidity). The first time trial was completed at a self-selected pace (SPTT). Durin...
OBJECTIVES With the growing demand for bone densitometry services there is a need for simple, cost-effective and ideally mobile devices which can identify individuals who are at risk of osteoporotic fracture. When new devices are evaluated, it is useful to examine the correlation with the established 'gold standard' technique of dual x-ray absorptiometry (DXA). This study examined the correlati...
We present density functional theory level predictions and analysis of the basic properties of newly synthesized high-nitrogen compounds together with 3,6-bis(2H-tetrazol-5-yl)-1,2,4,5-tetrazine (BTT) and 3,3'-azobis(6-amino-1,2,4,5-tetrazine) (DAAT), for which experimental data are available. The newly synthesized high-nitrogen compounds are based on tricycle fused 1,2,4-triazine and 1,2,4,5-t...
We introduce and study resource bounded random sets based on Lutz's concept of resource bounded measure ((7, 8]). We concentrate on n c-randomness (c 2) which corresponds to the polynomial time bounded (p-) measure of Lutz, and which is adequate for studying the internal and quantitative structure of E = DTIME(2 lin). However we will also comment on E2 = DTIME(2 pol) and its corresponding (p2-)...
Three neodymium complexes Nd(TTA)3(DMSO)2 (1, TTA = 2-thenoyltrifluoroacetone), Nd2(BDT)3(DMSO)6 (2, BDT = bis(4,4,4-trifluoro-1,3-dioxobutyl)thiophene) and Nd2(BTT)3(DMSO)4 (3, BTT = bis(4,4,4-trifluoro-1,3-dioxobutyl)(2,2'-bithiophene)) constructed from three thiophene-based β-diketonate ligands, were prepared for the purpose of building the relationships between the structures, energy levels...
INTRODUCTION Residual inhibition (RI) is the temporary inhibition of tinnitus by use of masking stimuli when the device is turned off. OBJECTIVE The main aim of this study was to evaluate the effects of RI induced by auditory electrical stimulation (AES) in the primary auditory pathways using early auditory-evoked potentials (AEPs) in subjective idiopathic tinnitus (SIT) subjects. MATERIALS...
OBJECTIVE The present study aims to find a convenient, rapid, and stable method to establish bladder tumor in mice. METHODS Female Balb/C-nu-nu nude mice (or female T739 mice) were narcotized by sodium pentobarbital at a dosage of 60 mg/kg. The stylet of the 24# venous retention needles was bent in a 5° to 7° angle at a distance of 15 mm from the needlepoint to form a circle with 2.61 mm to 3...
Introduction: The Hemoglobinopathies are one of the major public health problems in tribal predominant population. Objective: To estimate the seroprevalence of Sickle Cell Anemia and Thalassemia in suspected cases of genetic disorders by using HPLC retention time chromatogram method in tribal predominant population, Ranchi, Jharkhand. Methods: All Blood sample of suspected cases of genetic diso...
