The spatial distribution of excitement of receptors depends on the magnitude of amplitude of light integrated over the wavefront passing through the pupil as conditioned by the receptor’s acceptance lobe. Because the peripheral zones of the pupil are less efficient in eliciting visual excitation than the pupil’s centre, otherwise known as Stiles-Crawford effect of the first kind (SCE I), the sp...

We investigated whether photoreceptor function in amblyopic eyes differed from that in non-amblyopic eyes. Photoreceptor function was assessed with the optical Stiles-Crawford effect (SCE), psychophysical SCE, and foveal visual pigment density in both eyes of ten unilateral amblyopic subjects. Optical SCE and density measurements were carried out with a custom-built scanning laser ophthalmoscop...

This paper presents a high-level, visual Service Creation Environment (SCE) for web services. The SCE introduces two main concepts: services and composition templates. Composition templates are abstract descriptions of reusable compositions containing several placeholders for services. Services are verified to be compatible with the composition template when a service is mapped onto a compositi...

As aspiring respiratory physicians are aware, The Federation of Royal Colleges of Physicians of the UK (FRCPUK) has introduced Specialty Certificate Examinations (SCEs) to complement workplace-based assessments. Successful completion of the SCE in Respiratory Medicine is a prerequisite for Certificate of Completion of Training for all UK respiratory trainees whose specialist training began duri...

A brief description of chromosome aberrations and sister chromatid exchange (SCE) as cytogenetic endpoints for evaluation of DNA damaging agents is presented. Problems associated with the use of cytogenetic assays as population monitors of radiation and chemical exposures are discussed. Adequate cell sample size requirements and accurate assessment of cummulative exposure effects with increasin...

Abstract Negative attitudes of non-Singaporeans towards Singapore Colloquial English (SCE) are often used to support the “Speak Good Movement” in Singapore. This article examines spontaneous metalinguistic discourse about SCE an online Facebook group where Taiwanese migrants gather for mutual support. Based on idea that is mediated through social relation between interlocutors, this study revea...

Some environmental mutagenic agents cause genomic instability and increase susceptibility of DNA damage. One of them is mitomycin C which is connected to DNA as an alkylating factor and affects susceptible cells to reduction reactions. This drug is used in chemotherapy and treatment of tumors. Study of genomic instability in the presence of different concentrations of MMC can show susceptibilit...

Accurate prediction of fresh concrete slumps is a complex non-linear problem that depends on several parameters including time, temperature, and shear history. It also affected by the mixture design various ingredients. This study investigates efficiency three novel integrative approaches for predicting this parameter. To end, vortex search algorithm (VSA), multi-verse optimizer (MVO), shuffled...

The antidiabetic effect of a hot water extract of stems of Salacia chinensis (SCE) was evaluated in vivo in KK-Ay mice, a typical type 2 diabetes mellitus mice model. Administration of CE-2 dietary feed containing 0.25 and/or 0.50% of SCE for three weeks to KK-Ay mice significantly suppressed the elevation of both blood glucose and HbA1c levels without significant changes in body weight or food...

The ethyl, ethyl N-hydroxy, isopropyl, and methyl esters of carbamic acid were examined for their abilities to induce sister chromatid exchanges (SCEs) in alveolar macrophages, bone marrow, and regenerating liver cells of C57BL/6J X DBA/2J F1 mice. The relative potencies in inducing SCE, ethyl greater than ethyl N-hydroxy- greater than isopropyl, paralleled previously described activities for i...
