On some properties of weak solutions to elliptic equations with divergence-free drifts

We discuss the local properties of weak solutions to the equation $-\Delta u + b\cdot\nabla u=0$. The corresponding theory is well-known in the case $b\in L_n$, where $n$ is the dimension of the space. Our main interest is focused on the case $b\in L_2$. In this case the structure assumption $\operatorname{div} b=0$ turns out to be crucial

Estimates of solutions to the perturbed Stokes system

In this paper we derive local estimates of solutions of the Perturbed Stokes system. This system arises as a reduction of the Stokes system near a curved part of the boundary of the domain if one applies a diffeomorphism flatting the boundary. The estimates obtained in the paper play the crucial role in the investigation of partial regularity of weak solutions to the Navier-Stokes system near a curved part of the boundary of the domain

Mycotic dermatitis (Lumpy wool) and fleece rot of sheep

Matted and sometimes discoloured specimens of wool are often received at the Department of Agriculture during seasons of heavy rainfall. Two similar but quite distinct diseases are recognised as having caused this condition. They are mycotic dermatitis (lumpy wool) and fleece rot. Both conditions damage the fleece and render affected sheep susceptible to blowfly strike

Actinomycosis and Actinobacillosis

Actinomycosis and actinobacillosis, commonly known as lumpy jaw and wooden tongue respectively, are chronic infective diseases which are most commonly encountered in cattle, occasionally in pigs, and much less frequently in the other domestic animals and man. They are characterised by the presence of tumour-like swellings and exude pus containing yellow sulphur-like granules. These swellings are commonly found in or on the jawbones and tongue, but may be found on occasions, in other parts of the body such as the lungs, liver, spleen, etc

Recent Advances in Veterinary Medicine

During and since the years of World War II many notable advances have been made in the treatment of human ills and in many cases a secondary development of these discoveries has been the use of new substances in the treatment of disease in domestic animals

Diseases of goats

Many of the diseases of goats are common to sheep and cattle, and, as in these species, correct feeding, hygiene and general care and management will assist in the avoidance of serious ailments. In this article an attempt will be made to advise goat-owners on the diagnosis of the more common ailments, and suggestions as to treatment will be offered where possible. It should be appreciated however that where veterinary assistance is obtainable it is preferable to first-aid treatment. A qualified veterinarian has access to newer and more efficient methods of treatment than are available to the layman

Strychnine poisoning in dogs.

While there is considerable variation in the reaction of different species of animals to strychnine, the dog is particularly susceptible. The early symptoms of strychnine poisoning are anxiety and restlessness, followed by twitching and violent muscular contractions. The dog remains fully conscious until death occurs from asphyxia
