Abstract:

9075 Background: IL-2 is a T-cell growth factor tested in a variety of regimens for advanced melanoma (MEL) and renal cell carcinoma (RCC). High-dose IL-2 (600,000-720,000 IU/kg administered intravenously every 8 hours for up to 14 consecutive doses) was approved by FDA for advanced MEL and RCC in 1998 based upon the durability of responses observed. Early studies of HD IL-2 reported overall (OR) and complete response (CR) rates of 16% and 8% respectively. Severe toxicity limited use to specialized centers with standardized protocols, either intensive care (ICU) or oncology specialty settings.

Abstract:

Al2O3 grown by Atomic Layer Chemical Vapour Deposition (ALCVD) on n-type 4H-SiC with a nominal thickness of 100nm has been characterized by Grazing Incidence X-Ray Diffraction (GIXD) and Specular X-Ray Reflectivity (SXR) measurements. After post-deposition, the samples were annealed at different temperatures and durations in argon atmosphere. The GIXD results reveal crystallization at temperatures above 900°C, most likely in the form of θ-Al2O3 or γ-Al2O3. However, the formation of a new, non-stoichiometric Al2O3 phase cannot be excluded.

Abstract:

A novel approach to fabrication of globularized fine-grained structure in γ+α2 titanium aluminide alloys has been proposed. The approach included the use of a specially designed alloy Ti-43Al-X(Nb,Mo,B) and heat treatment. It was found that the ingot structure of the alloy might be partially globularized on a scale of bulk material using only globularization anneal excluding any hot working procedure. The microstructure and tensile mechanical properties of the alloy in the cast + heat treated condition were investigated. The tensile mechanical tests were performed in air in the temperature ran

The sub-structure of these states in terms of two and four quark components, as well as a glueball component is explored, and its correlation with the mass of f0(1370) is studied.

Abstract:

This essay analyses how Euripides reused the epic pattern of the so-called τις-Rede or tis-speech, used by Homer sometimes to make a character speculate about what someone might say, other times to give a single and anonymous example of a crowd’s opinion. Euripides uses both the traditional epic models in his tragedies: potential τις-Reden (Alc. 954-61, 995-1005; Her. 26-30, 515-9; Pho. 578-83; fr. 708 K.) and actual τις-Reden (Andr. 1104-6; Hel. 1589-91; HF 950-2).

Abstract:

The long-term soil temperature monitoring in the area of more than 550 km in length within the region of Transbaikalia has been carried out. Sites for the monitoring were represented by the forest-steppe vegetation of different ecotopological and ecogeographical patterns. It was revealed that the dynamics of temperature regimens are highly synchronized reflecting the macroclimatic unity of the region. The sufficiently higher heat supply on the southerly exposed slopes comparing to northerly exposed ones was demonstrated. The distinctness between soil temperature regimens in different sites was

Abstract:

Tree cover maps derived from satellite and aerial imagery directly support civil and military operations. However, distinguishing tree cover from other vegetative land covers is an analytical challenge. While the commonly used Normalized Difference Vegetation Index (NDVI) can identify vegetative cover, it does not consistently distinguish between tree and low-stature vegetation. The Forest Cover Index (FCI) algorithm was developed to take the multiplicative product of the red and near infrared bands and apply a threshold to separate tree cover from non-tree cover in multispectral imagery (MSI)

Abstract:

Public transportation is an essential part of many older adults’ lives, but the pandemic presented new challenges for the vulnerable population. Adults aged 65 years and older experienced additional challenges, such as limited mobility options (e.g., lack of buses or trains in service due a combination of government lockdowns, fear of contracting or spreading the virus, and driver shortages in certain areas) because of the pandemic, which may have resulted in more age-related declines in perceptual, cognitive, and physical functioning. This study explores how older adults living in major metro

Abstract:

Cationic polypeptide proteins found in the seeds of the tropical plant Moringa oleifera have coagulation efficiencies similar to aluminum and ferric sulfates without their recalcitrant nature. Although these proteins possess great potential to augment or replace traditional coagulants in water treatment, harvesting active protein from seeds is laborious and not cost-effective. Here, we describe an alternative method to express and secrete active M. oleifera coagulant protein (MO) in Bacillus subtilis.

Abstract:

Hanging gardens are the most common type of spring at Arches National Park (NP) and Natural Bridges National Monument (NM). They are also present at Canyonlands National Park, but hanging gardens are rare off the Colorado Plateau. Their cliffside setting provides stable access to water without flood disturbance. This combination provides unique habitat that is rich in endemic plant species. The diffuse, seeping emergence of water makes measuring springflow impossible at most sites. Park managers have an interest in monitoring hanging gardens—especially as the climate warms and aridity and wate
