Melasma management is frequently difficult, with many examples of inadequate remission and repeated relapses. Depending on the patient's features clinical presentation, a multimodal treatment involving photoprotection, skin lighteners, exfoliants, antioxidants, rejuvenation operations necessary in most situations.

a series of tialon coatings were synthesized in a gaseous mixture of argon, nitrogen and oxygen by cathodic arc evaporation method using a ti–al mosaic target. oxidation of coatings was carried out by heating the coated samples at the temperatures of 500, 600, 700, and 800°c for 1 h in air atmosphere. it was found that heat treatment changed the microstructure and composition of the coating. th...

reaction constants and heat release during thermophilic aerobic digestion of typical secondary and mixed sludges were determined. maximum reaction constant, determined by measuring the amounts of biodegradable volatile suspended solids (bvss) removed, occurred in the temperature range of 55-60 ºc. measurement of heat releases were carried out, at the same range, by the aid of a temperature prog...

Structural rejuvenation in metallic glasses by a thermal process (i.e. through recovery annealing) was investigated experimentally and theoretically for various alloy compositions. An increase in the potential energy, a decrease in the density, and a change in the local structure as well as mechanical softening were observed after thermal rejuvenation. Two parameters, one related to the anneali...

in the present study, the capability of accumulative roll bonding (arb) and subsequent heat-treatment to fabricate solid solution from a multilayered cu/zn/al was investigated. two post-heat treatment (one-step and two-step) routes were proposed. in the first, the arb processed material was heated to 800 c for 5:30 hours and allowed to cool slowly in a furnace (one-step route). in the second (t...

Elderly people may remember the drug peddlers who frequented the noisy country markets when they were growing up. Even though it was difficult to trust the peddlers, it was even more difficult to resist the temptation to buy their goods. They volubly emphasized that their products could be a silver-bullet potion for rejuvenation. Attracted to such suspicious advertisements, more than a few gull...

We describe how legacy C++ programs can be rejuvenated using C++11 features such as generalized constant expressions, perfect forwarding, and lambda expressions. In general, this work develops a correspondence between different kinds of macros and the C++ declarations to which they should be transformed. We have created a set of demacrofication tools to assist a developer in the rejuvenation of...

The growing burden of the rapidly ageing global population has reinvigorated interest in the science of ageing and rejuvenation. Among organ systems, rejuvenation of the central nervous system (CNS) is arguably the most complex and challenging of tasks owing, among other things, to its startling structural and functional complexity and its restricted capacity for repair. Thus, the prospect of m...

the effect of t6 heat treatment on the microstructure and wear behavior of al-332 piston alloy containing 1.2wt% iron was investigated. the results showed that the t6 heat treatment changed the morphology of acicular eutectic si particles to a more spherical form. the heat treatment also reduced the average length and blunted the needle-like ?- phase intermetallics through dissolution and fragm...
