Angles of incidence p waves were obtained from the records short and long period seismographs W.W.S.S.N. at Shillong. The study covers range epicentral distances 200 to 1000. observations indicate that velocity P earth’s surface is approximately 6 km/sec which upper layer (granitic layer) earth.

In this paper, an ultra-wideband metamaterial absorber is designed and simulated. The proposed absorber is planar and low profile. It is made of a copper sheet coated with two dielectric layers. Each unit cell of the metamaterial structure is composed of multiple metallic split rings, which are patterned on the top and middle boundaries of the dielectrics. The designed absorber utilizes differe...

Marija RADENKOVIĆ Clinic for Eye Diseases Clinical Center of Niš Bulevar dr Zorana Djindjića 48 18000 Niš Serbia [email protected] SUMMARY Introduction Ocular surface disease (OSD) is a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbances, tear film instability with potential damage to the ocular surface, accompanied by increased tear ...

Multispectral terrestrial laser scanning (TLS) is an emerging technology. Several manufacturers already offer commercial dual or three wavelength airborne laser scanners, while multispectral TLS is still carried out mainly with research instruments. Many of these research efforts have focused on the study of vegetation. The aim of this paper is to study the uncertainty of the measurement of spe...

OBJECTIVES To determine the incidence of acute primary angle-closure glaucoma in the Hong Kong Chinese population, and to identify risk factors for this condition. DESIGN Prospective study. SETTING University teaching hospital, Hong Kong. PARTICIPANTS Patients with acute primary angle-closure glaucoma presenting between 1 March 1998 and 29 February 2000.

Infrared multiple-angle incidence resolution spectrometry (IR-MAIRS) is a recently developed spectroscopic technique that combines oblique transmission measurements and chemometrics (multivariate analysis) to obtain both pure in-plane (IP) out-of-plane (OP) vibration spectra for thin sample. IR-MAIRS established analyzing the molecular orientation of organic films at atmospheric pressure, but i...

Background: more than 50% of newly diagnosed primary open-angle glaucoma (POAG) patients are in the moderate or advanced stages. It is difficult to assess disease course due limited official data. On a national scale, prevalence and incidence measures that hardly provide complete "landscape" this issue Russia. Aim: determine prognosis changes epidemiological indicators (prevalence incidence) PO...
