This research describes an optimization and rejuvenation of the heat treatment process for a nickel base superalloy grade GTD111 after long-term service. The aging variables examined in this study included primary temperature, time, secondary time. resulting materials were using Taguchi method design experiments to determine material hardness test observed with hot tensile test, scanning electr...

gd2o3 nanoparticles were prepared by a two–step process; cathodic electrodeposition followed by heat-treatment method. first, gd(oh)3 nanoparticles was galvanostatically deposited from nitrate bath on the steel substrate by pulse current (pc) mode. the deposition experiments was conducted at a typical on-time and off-time (ton=1ms and toff=1ms) for 60 min. the electrodeposited precursor was the...

Since 2004, the Italian Department for Civil Protection and the Ministry of Health have implemented a national program for the prevention of heat-health effects during summer, which to-date includes 34 major cities and 93% of the residents aged 65 years and over. The Italian program represents an important example of an integrated approach to prevent the impact of heat on health, comprising Hea...

Software aging and rejuvenation research has shown that the application of approaches for software aging modeling, monitoring, and rejuvenation has the potential to significantly increase software resilience. In this chapter, we present an overview of important analytical models and measurement approaches for software aging and rejuvenation. We start by describing the Markov based approaches an...

Overview The demand for facial skin rejuvenation has seen recent, unprecedented growth. As people have become more aware about their cosmetic appearance, there has been a greater demand for newer technologies for treating aged and actinically damaged facial skin. Despite various methods available, the use of chemical peeling agents continues to be the gold standard. Chemical peeling is a proced...

BACKGROUND Postoperative pain is a major concern for patients undergoing facial aesthetic surgery. Aggressive efforts to reduce postoperative pain while avoiding adverse sequelae, such as nausea and vomiting, will result in an improved patient experience. Newer pharmaceuticals, medical devices, and longer-acting local anesthetics offer the potential to reduce pain and enhance patient satisfacti...

Software rejuvenation has been addressed in hundreds of papers since it was proposed in 1995 by Huang et al. The growing number of research papers shows the great importance of this topic. However, no paper has studied yet software rejuvenation in the real world. This paper investigates to what extent software rejuvenation techniques are integrated in the IT and Telco solutions. For this purpos...

INTRODUCTION This study describes a pivotal clinical trial of a new minimally invasive cosmetic procedure for facial rejuvenation and for the treatment of scars and wrinkles. METHODS The procedure consisted of a combination of techniques such as fillers, biorevitalization, peeling, and intradermal radiofrequency, emitted from a new device denominated by Spherofill Medical Plus (SMP; Spherofil...

Laser technology and other energy sources are rapidly finding a place in dermatology clinics. In the field of skin rejuvenation by fractional photothermolysis, although few controlled studies have been undertaken, several devices have emerged in recent years that appear less effective than laser ablation techniques but that are safer. The aim of this short article is to provide an introduction,...

BACKGROUND The use of growth factors in skin rejuvenation is emerging as a novel anti-aging treatment. While the role of growth factors in wound healing is well established, their use in skin rejuvenation has only recently been to be studied and no controlled trials have been performed. OBJECTIVE We evaluated the anti-aging effects of secretory factors of endothelial precursor cells different...
