Abstract Background To study optic disc features of premature infants and compare to that term explore the pattern newborn development provide basis for diagnosis disease. Methods This was a prospective clinical research. Newborns underwent fundus disease screening from January 1st, 2016 October 31st, in neonatal ward Ruian City Maternal Child Health Hospital were selected. RetCam 3 Version6.1....

CASE REPORT A 34- year- old man affected by Klinefelter syndrome, with loss of vision in his left eye, ocular hypertension with increased cupping in both eyes, and optic disc pit with serous macular detachment in the left eye. Optical coherence tomography showed a macular detachment with a double-layer detachment, consisting of both an inner layer separation and an outer layer detachment. The o...

We have performed a shape optimization of the disc in an industrial double-eccentric butterfly valve using the effect analysis of design variables to enhance the valve performance. For the optimization, we select three performance quantities such as pressure drop, maximum stress, and mass (weight) as the responses and three dimensions regarding the disc shape as the design variables. Subsequent...

Clinical history A 72 year old male patient presented with recent onset thoracic back pain. The pain was continuous and intense, exacerbated by movements of the spine, and radiated bilaterally to the costal region. The patient was known to suffer from non-insulin-dependent diabetes mellitus and hypertension. On admission, he appeared unwell and had a fever of 37.5'C. Clinical examination reveal...

We present Doppler and modulation tomography of the X-ray nova XTE J1118+480 with data obtained during quiescence using the 10-m Keck II telescope. The hot spot where the gas stream hits the accretion disc is seen in Hα, Hβ, He i λ5876, and Ca ii λ8662, thus verifying the presence of continued mass transfer within the system. The disc is clearly seen in Hα and Ca ii λ8662. We image the mass-don...

Magnetorheological (MR) brake is a sort of electromagnetic that uses the controllable output characteristics MR fluid for braking. In this paper, an with double disc was developed to improve braking performance conventional brakes. The effective damping gaps were increased from traditional two sections four by increasing single disc. By reasonably arranging non-magnetic sleeve inside brake, mag...

We derive age-metallicity relations (AMRs) and orbital parameters for the 1658 solar neighbourhood stars to which accurate distances are measured by the HIPPARCOS satellite. The sample stars comprise 1382 thin disc stars, 229 thick disc stars, and 47 halo stars according to their orbital parameters. We find a considerable scatter for thin disc AMR along the one-zone Galactic chemical evolution ...

background: resistance to contemporary broad-spectrum b-lactam antibiotics mediated by extended-spectrum b-lactamases (esbls) is increasing worldwide. klebsiella pneumoniae , an important cause of nosocomial and community acquired urinary tract infections has rapidly become the most common esbl producing organism. we examined esbl production in urinary isolates of k. pneumoniae in relation to t...
