The design factors (indoor plants, workstation partitions, and operable windows) that predict sick building syndrome (SBS) were described for architects and interior designers. For facility management, the indoor environmental characteristics (thermal comfort, air quality, noise and lighting) that contribute to SBS symptoms were investigated. This study used a standard Building Use Studies (BUS...

A representative sample of elderly people residing in the community was examined to establish their psychiatric status. An interview with a close friend or relative, focusing on a one-week period in 1981, was used to investigate each subject's functional limitations and troublesome behaviour, these being the two components of the Social Breakdown Syndrome. The data from the sample were weighted...

Stimulated Brillouin scattering (SBS) has become a favorable underlying mechanism in many demonstrations of all-optical variable delay in standard fibers, often referred to as slow and fast light. Over 100 journal papers and numerous conference sessions have been dedicated to SBS slow light since 2005. In this paper, recent research in this area is reviewed. Following a short introduction to th...

Temporal compression of nanosecond pulses from a commercial Q-switched Nd:YAG laser at second and third harmonic into the sub-nanosecond regime is demonstrated. In a geometry consisting of a single cell only, compression in several liquid media is investigated. For both 532 and 355 nm smooth and reliable operation is obtained with output pulses as short as 200 ps. A new concept is proposed to s...

OBJECTIVES This study sought to assess the effect of curcumin nanoparticles (curcNPs) on antimicrobial property and shear bond strength (SBS) of orthodontic composite to bovine enamel. MATERIALS AND METHODS In this in vitro, experimental study, 1%, 5% and 10% curcNPs were added to Transbond XT composite. Stainless steel brackets were bonded to 48 sound bovine incisors in four groups (n=12) us...

Two forms of undulatory locomotion in the lamprey (a lower vertebrate) have been described earlier: fast forward swimming (FFS) used for long distance migrations and slow backward swimming (SBS) used for escape from adverse tactile stimuli. In the present study, we describe another form of escape behavior: slow forward swimming (SFS). We characterize the kinematic and electromyographic patterns...

OBJECTIVE To evaluate the effects of ultrasonic instrumentation with different scaler-tip angulations on the shear bond strength (SBS) and bond failure mode of metallic orthodontic brackets. METHODS Adhesive pre-coated metallic brackets were bonded to 72 extracted human premolars embedded in autopolymerizing acrylic resin. The teeth were randomly divided into 3 groups (n = 24 each) to undergo...

Straight back syndrome (SBS) is a congenital disease of the thoracic spine and was described in 1960 by Dr Rawlings as a new cause of pseudo-heart disease as mentioned above. The pathology of SBS is defined as the loss of normal kyphosis of the thoracic spine that causes an abnormal straightness of the upper back. The thoracic spine in SBS is more straight than normal but is not stiff and can f...

Distributed measurements of the Brillouin gain spectrum in a photonic crystal fibre have been carried out for the first time to our knowledge. These measurements confirm the strong increase of the Brillouin threshold as resulting from the broadband and multimode nature of the Brillouin gain spectrum all along the fibre. INTRODUCTION The periodic wavelength-scale air-hole microstructure of solid...

Possible relations between incidence and prevalence of sick building syndrome (SBS), indoor exposures, and personal factors were studied in a four year longitudinal study among personnel (n = 129) in six primary schools. The mean concentration of carbon dioxide was above the recommended value of 0.08 microliter/l (800 ppm) in all schools, indicating a poor outdoor air supply. Indoor concentrati...
