BACKGROUND Central centrifugal cicatricial alopecia is the most common form of cicatricial alopecia in African American women. Treatment options are limited and mostly aimed at halting further hair loss but rarely result in hair regrowth. Therefore, it is important to recognize early clinical signs, perform a confirmatory biopsy, and begin treatment promptly. We have observed that hair breakage...

In auditory cortex of the mustached bat, the FF (F means frequency modulation), dorsal fringe (DF), and ventral fringe (VF) areas consist of "combination-sensitive" neurons tuned to the pair of an emitted biosonar pulse and its echo with a specific delay (best delay: BD). The DF and VF areas are hierarchically at a higher level than the FF area. Focal electric stimulation of the FF area evokes ...

Water as a refrigerant (R718) is compared with other modern refrigerants (R717, R290 R134a, R12, R22, and R152a) regarding refrigeration capacity and COP (coefficient of performance). A computer program simulating a theoretical vapor compression refrigeration cycle was developed to calculate COPs, compression ratios, and discharge temperatures of the refrigerants from the compressor. The effect...

Background: Previous studies indicate that running at maximum speed on short or curved sections is slower than straight sections. This study aimed to analyse the external load symmetry in track kinematics concerning body location (left vs. right, caudal cephalic), segment (straight curved) and distance (150 m 300 m). Methods: Twenty experienced athletes ran 150 an official athletic were monitor...

Bacterial recovery by a portable Reuter centrifugal air sampler and a standard Mattson-Garvin slit-to-agar air sampler was compared in a series of experiments. Microbial air quality was monitored in seven typical laboratory locations. Tests showed that the Reuter centrifugal air sampler yielded significantly higher recoveries than did the slit-to-agar unit.

Nowadays, the prestressed centrifugal concrete piles (PCCP) are applied in most major construction projects Hai Duong city. The pile bearing capacity and static jacking load (Pep) very important parameters for optimizing foundation design, they depend on types of ground structure. paper introduces estimated method which was two structure city (type I type II). results showed that maximum (Pepma...
