The relationship between color and perceived depth for realistic, colored objects with varying shading was explored. Background: Studies have shown that warm-colored stimuli tend to appear nearer in depth than cool-colored stimuli. The majority of these studies asked human observers to view physically equidistant, colored stimuli and compare them for relative depth. However, in most cases, the ...

The Background and Objectives: A sciatic nerve block at the level of the popliteal fossa is frequently administered for post-operative analgesia for surgery below the knee. While ultrasound continues to gain popularity as the technique of choice for guiding needle positioning during peripheral nerve blocks, practitioners can begin to utilize ultrasound to look for patterns of anatomical signifi...

BACKGROUND Disposable-syringe jet injectors (DSJIs) have the potential to deliver vaccines safely and affordably to millions of children around the world. We estimated the incremental costs of transitioning from needles and syringes to delivering childhood vaccines with DSJIs in Brazil, India, and South Africa. METHODS Two scenarios were assessed: (1) DSJI delivery of all vaccines at current ...

This paper will present details of a system that allows for an evolutionary introduction of depth perception into the existing 2D digital TV framework. The work is part of the European Information Society Technologies (IST) project “Advanced Three-Dimensional Television System Technologies” (ATTEST), an activity, where industries, research centers and universities have joined forces to design a...

We develop the device model for proposed injection (electrically) driven thermal light emitters (IDLEs) based on vertical hexagonal boron nitride layer/graphene layer/ layer (hBNL/GL/hBNL) heterostructures and analyze their dynamic response. The operation of IDLEs is associated with emission hot two-dimensional electron-hole plasma (2DEHP) generated in GL by both lateral from side contacts thro...

We apply recent results in queueing theory to propose a methodology for bounding the buffer depth and packet delay in high radix interconnection networks. While most work in interconnection networks has been focused on the throughput and average latency in such systems, few studies have been done providing statistical guarantees for buffer depth, packet reordering and packet delays. These param...

Abstract As a result of deep burial depth, small pore throat, poor connectivity between pores, different clay mineral contents in reservoirs, and strong reservoir sensitivity, injection wells often have problems such as rapidly increasing water-injection pressure insufficient quantity the process development. The main measures used to solve difficulties water low-permeability reservoirs include...

The savannas (called Cerrado) are the second-largest vegetation formation in Brazil after Amazon rainforest, with about 2 million km2. Roots have been found very deep soil layers Cerrado ecosystems, which suggests a crucial role of rooting supply water and nutrients over dry periods. aim our study was to gain insight into complementarity common woody species taking up mobile throughout profiles...

background: pain originating from intramuscular (im) injection should not be underestimated, because it can damage the nurse–patient relationship. this research aimed at answering two main questions, whether acupressure is effective on pain severity dueto im injection or not and whether pain severity in two groups is different or not. materials and methods: this research was performed in govern...

this study determined the clinical effect of subconjunctival administration of bevacizumab in patients with primary and recurrent pterygium. the study was an off-label, single-dosing, interventional case series involving 22 patients with primary and recurrent pterygium. they received subconjunctival bevacizumab (0.2cc). pterygium vascularity and thickness was graded. the size of the pterygium (...
