Surface acoustic wave (SAW) atomization is an attractive approach for generating monodispersed microdroplets for a diversity of applications, from drug delivery to mass spectrometry, due to its reliability, miniaturizability, and portability. Here, we demonstrate a nozzleless spray cooling technique based on SAW atomization, with the key advantage of downward scalability: increasing the operati...

A numerical study has been carried out for slot air jet impingement cooling of horizontal concentric circular cylinders. The slot air jet is situated at the symmetry line of a horizontal cylinder along the gravity vector and impinges on the bottom of the outer cylinder which is designated as θ=0°. The outer cylinder is partially opened at the top with a width of W=30mm and is kept at constant t...

Pain and local complications are the major determinants of outcome after inguinal hernia repair. To evaluate the respective impact of peri-operative cooling of surgical site and usual care after open inguinal hernia repair, we performed a prospective randomized study. Methods: One hundred and eight consecutive patients with primary unilateral inguinal hernia were included the study. Repair was ...

Simulated Annealing is one the most well known local search methods. In practice, it is often used to solve discrete optimization problems; especially very tough problems, [54, 37, 34, 3, 2, 41]. Global optimization is computationally extremely challenging and for large instances, exact methods reach their limitations quickly. Hence, in practice, often local optimization methods are used. Simul...

background: the phase change materials (pcms) have the appropriate properties for controlling heat strain. one of the well-known pcms is paraffin. this study aimed to design the cooling vest from the cheap commercial paraffin compound and evaluation of its effectiveness under laboratory hot conditions. methods: the cooling vest was made of the polyester fabric and it had 17 aluminum packs. the ...

Central cluster galaxies in cooling flows show the signatures of gaseous accretion and ongoing star formation at rates ranging between ∼ 1 − 100 M⊙ yr −1. Their blue morphologies usually reflect the low net angular momentum content of the T < 104 K gas from which the accretion population formed, and the effects of interactions between the cool gas and their FR I radio sources. For example, ther...

Intraspecific variation in avian thermoregulatory responses to heat stress has received little attention, despite increasing evidence that endothermic animals show considerable physiological variation among populations. We investigated seasonal (summer versus winter) variation in heat tolerance and evaporative cooling in an Afrotropical ploceid passerine, the white-browed sparrow-weaver (Plocep...

The purposes of this study were to assess the expression patterns of heat shock proteins (Hsps), after eyeball heating or cooling, and to elucidate their relationships with corneal wound healing and intraocular complications after excimer laser treatment. Experimental mice were grouped into three according to local pretreatment type: heating, cooling, and control groups. The preconditioning was...
