1. Motivation. Let J0(N) denote the Jacobian of the modular curve X0(N) parametrizing pairs of N -isogenous elliptic curves. The simple factors of J0(N) have real multiplication, that is to say that the endomorphism ring of a simple factor A contains an order in a totally real number field of degree dimA. We shall sometimes abbreviate “real multiplication” to “RM” and say that A has maximal RM ...

Data relating to reproductive parameters of German shepherd bitches were collected from registered German shepherd dog (GSD) breeders with information kept over a 15-year period (1982-1997). The information obtained was verified using the East African Kennel Club records. A total of 594 bitches from 280 breeders were recorded. From these, 798 heats were observed, 594 of which were used for bree...

During my first year of studies at the École Normale Supérieure in Paris, our teacher, Eugène Bloch, introduced us to quantum physics, which at that time was little taught in France. Like he, I was of Alsatian extraction and knew German. He strongly advised me to read Sommerfeld’s admirable book Atombau und Spektrallinien . In the course of this reading, I became particularly interested in the ...

A great number of organic and inorganic substances pollute the water of the Rhine. The greatest concentration is formed by the chlorides, as their quantity exceeds that of the suiphates by about 50 per cent. At the German—Dutch frontier, the mean annual value of the chloride charge of the river amounts to approximately 350 kg/s C1. About 40 per cent, or 130 kg/s, of this quantity are residual s...

Case report. A 14-year-old schoolboy was bitten by an Alsatian dog, sustaining a puncture wound over the dorsal surface ofthe terminal interphalangealjoint of the right little finger. Primary closure of the wound was performed without wound toilet and no antibiotics were given. One week later the wound was infected and flucloxacillin was prescribed. He continued to have considerable pain, swell...

Some dog breeds, including the German shepherd dog (GSD), are predisposed to immune-related disorders. The authors prospectively described development of serum and faecal IgA and serum IgE in GSD from puppies until adulthood and the relationship between mothers and their offspring. Further, the authors tested whether dogs with lower serum IgA also have low faecal IgA and/or serum IgE. To reveal...

Diphallia or penile duplication is a rare congenital abnormality thought to result from duplication of the cloacal membrane in the early developmental stages in the uterus. The present case concerned a 4-year old intact male German shepherd dog. The patient presented with a complaint of paraphimosis. Clinical, laboratory, radiological and ultrasonographic examinations were carried out. Semen sa...

Clostridial myositis, considered to be rare in pet animals, is an acutely fatal toxaemic condition. Some species of clostridia are responsible for necrotic myositis. A 2-year-old male German shepherd dog was admitted with non-weight bearing lameness and massive swelling of the left hind limb. Clostridium perfringens type A with alpha toxin was diagnosed as a pathogenic agent. Based on ...
