We present optical and near–infrared spectroscopic observations of the optical Einstein ring 0047–2808. We detect both [OIII] lines λλ4959, 5007 near ∼ 2.3μ, confirming the redshift of the lensed source as z = 3.595. The Lyα line is redshifted relative to the [OIII] line by 140± 20 km s. Similar velocity shifts have been seen in nearby starburst galaxies. The [OIII] line is very narrow, 130 km ...

In this paper, we considered the half logistic model and derived a probability density function that generalized it. The cumulative distribution function, the $n^{th}$ moment, the median, the mode and the 100$k$-percentage points of the generalized distribution were established. Estimation of the parameters of the distribution through maximum likelihood method was accomplished with the aid of c...

This 68-year-old patient with Stage 4 chronic kidney disease was reviewed in our low clearance clinic 2 months after formation of a left arteriovenous fistula. The prominent ‘half-and-half’ appearance of his nails was noted. Nail disorders are common in chronic renal failure, affecting up to 70% of haemodialysis patients [1]. Half-and-half or Lindsay nails [2], where the proximal half of the na...

A spectre is haunting biology in America the spectre of Creationism. We scientists believed that this religious intruder had been fatally wounded in the aftermath of the Scopes trial. Sharing the ’fifties prestige of science with Our Friend, the Atom, the biology profession had, so we thought, nailed its coffin shut. But now, risen, garbed in the raiment of Intelligent Design, this poltergeist ...

Software often goes through a variety of extensions during its lifetime: adding new fields or new variants to a data structure, retroactively creating new type abstractions, and adding new operations on a data structure. As characterized by the extensibility problem, it should be possible to apply any combination of these types of extensions in any order. Mainstream object-oriented languages, h...

A 14-month-old child was diagnosed with a Veau Class II cleft palate. Von Langenbeck palatoplasty was performed for the right palate, and V-Y pushback palatoplasty was performed for the left palate. The child did not have a special problem during the surgery, and the authors were able to elongate the cleft by 10 mm. Contrary to preoperative concerns regarding the hybrid use of palatoplasties, t...
