Contribution to the biology and geographical distribution of Aegagropila sauteri (Nees) Kutz. [Translation of: Gidrobiologicheskie Zhurnal, Kiev 4(3), 68-69, 1967]

Aegagropila sauteri is a peculiar green algae, the branched thalli of which, according to the amount of growth, forms velvety spheres of a diameter of 3-4, sometimes to 5-6 cm. and bigger. Investigators attribute it to a special genus of green algae. The authors examine Aegagropila sauteri in Lake Markakol (Kazakhstan).

'Ascendency's ... last big jamboree':Big house society in Northern Ireland 1921-69

Thie examines the continuing role that the landed class enjoyed in Northern Ireland in contrast to the experience of their fellow landlords in the rest of Ireland following Partition. It argues that the senses of tradition and continuity which the unionist population in particular attributed to the old landed elite gave them an important role in bolstering the newly created state of Northern Ireland. In turn this allowed them to continue acting as a social elite long after the economic and political foundations of their ascendancy had been removed.

Predicting the need for insulin therapy in late onset (40-69 years) diabetes mellitus

A six-year prospective study of 144 newly diagnosed, symptomatic diabetic patients aged 40-69 years showed that 21 (15%) required insulin therapy, commencing 1-61 months after diagnosis. The plasma insulin response to oral glucose was assessed at the time of diagnosis. All 12 patients with very low peak insulin response (less than or equal to 6 mU/l) required insulin therapy. Thirty-six patients had an intermediate insulin response (greater than 6 less than or equal to 18 mU/l); of these, 7 with a mean weight 88% (range 73-96%) of average body weight required insulin, while 29 with a mean weight 117% (range 98-158%) of average body weight, did not. Ninety-six patients had a peak insulin response (greater than 18 mU/l); 2 patients whose weights were 96% and 100% of average body weight, required insulin, while the remainder did not. Consideration of initial body weight and peak insulin response provides a useful prediction of the eventual need for insulin.

Comment on "On the Uniqueness of Stable Marriage Matchings" [Economic Letters 69(1):1-8, 2000]

We prove with the help of a counterexample that Lemma 6 and Corollary 7 from Eeckhout [1] are incorrect.

Obesity and occupational injury:a prospective cohort study of 69,515 public sector employees

Obesity and overweight are suggested to increase the risk of occupational injury but longitudinal evidence to confirm this is rare. We sought to evaluate obesity and overweight as risk factors for occupational injuries.
