Patients with thick skin mainly exhibit the aging processes of sagging, whereas patients with thin skin develop wrinkles or volume loss. Asian skin is usually thicker than that of Westerners; and thus, the sagging of skin due to aging, rather than wrinkling, is the chief problem to be addressed in Asians. Asian skin is also relatively large in area and thick, implying that the weight of tissue ...

When you lean back for take-off in a jumbojet, maybe the following question flashes through your mind: How is it possible that the 400 squaremeter wings can carry 400 tons at a wingload of 1 ton per squaremeter in sustained flight in the air? Or maybe you are satisfied with some of the explanations offered in popular science, like higher velocity and lower pressure on the upper surface of the w...

The work describes the production of alkaline protease in a lab scale fermentor from Bacillus subtilis IH-72. The production of alkaline protease was enhanced by optimization of cultural conditions in a stirred fermentor. The alkaline protease so produced was applied to the goat skin for the removal of hair. The skin pieces were treated in three different ways; singly with the enzyme, in combin...

Strain improvement and medium optimization to increase the productivity of spiramycin were carried out. Of oil tolerant mutant strains screened, one mutant, Streptomyces ambofaciens XC 2-37, produced 9% more spiramycin than the parent strain S. ambofaciens XC 1-29. The effects of soybean oil and propyl alcohol on spiramycin production with S. ambofaciens XC 2-37 were studied. The potency of S. ...

Cell culture in shake flask and air-lift bioreactor was carried out to exploit the potential of Arnebia sp. for napthoquinone metabolite production. Cell suspension cultures of Arnebia were established from friable callus in liquid MS medium supplemented with 6-benzylaminopurine (BAP) (10 μM) and indole-3-butyric acid (IBA) (5 μM). Growth kinetic studies were done by using settled cell volume a...

This paper presents an analysis of the concept of Miniature Air Vehicles and Micro Air Vehicles (respectively mAV and μAV) mainly carried out through the development of a mAV prototype called "Bidule", which was first successfully flown in 1998. The final objective of the project is to reduce the size of this miniature demonstrator to a micro sized vehicle. This paper presents the initial work ...

Using a unique data set with 168 ski resorts located in France, this paper investigates the relationship between lift ticket prices and supply-related characteristics of ski resorts. A nonparametric analysis combined with a principal component analysis is used to identify the set of efficient ski resorts, defined as those where the lift ticket price is the cheapest for a given level of quality....

The PHOENICS code is employed to perform numerical simulations of gas-liquid two-phase bubbly flows in large vertical flow channels. Air-water and steam-water flows in large diameter pipes are simulated using the built-in two-fluid option of the code where liquid and gas are modeled as two interacting continua. The code is utilized in conjunction with advanced twophase flow models, accounting f...
