The possibility to conduct simulations of homogeneous nucleation of argon from a supersaturated vapor phase using a microcanonical or NVE ensemble is evaluated (NVE: number of particles N, volume V, and energy E are constant). In order to initiate a phase separation kinetic energy is removed from the system in one step which transfers the system into a supersaturated state. After this temperatu...

Since monosodium urate (NaU) may play an important etiologic role in the formation of renal stones containing Ca in patients with hyperuricosuria, the current studies were undertaken to define some of the physiocochemical factors which determine the formation of NaU. In solutions containing Na, uric acid was rapidly transformed to NaU at pH greater than 6. The results indicated that NaU, and no...

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by rapidly progressive degeneration of motor neurons in the brain and spinal cord. Although most forms of ALS are sporadic (sALS), ∼10% of cases are inherited in families (fALS). More than 50 ALS genes have been identified, with 16 of them unequivocally implicated in the pathogenesis (1). These genes function...

A class of supersaturated designs called k-circulant designs is explored. These designs are constructed from cyclic generators by cycling k elements at a time. The class of designs includes many Es2-optimal designs, some of which are already known and some of which are more efŽ cient than known designs for model estimation under factor sparsity. Generators for the most efŽ cient designs are lis...

We shall consider graphs (hypergraphs) without loops and multiple edges . Let Ybe a family of so called prohibited graphs and ex (n, Y) denote the maximum number of edges (hyperedges) a graph (hypergraph) on n vertices can have without containing subgraphs from Y A graph (hypergraph) will be called supersaturated if it has more edges than ex (n, Y). If G has n vertices and ex (n, Y)=k edges (hy...

It was shown in a recent publication (1) that blood serum is normally supersaturated with tertiary calcium phosphate, and the suggestion was made that other body fluids are similarly supersaturated with this salt. In order to confirm this idea, solubility experiments were undertaken with cerebrospinal fluid; it was furthermore hoped that these studies might throw some light on the question of t...

The broadening of the three hyperfine EPR nitroxide lines in oxygen supersaturated solutions was examined. The solutions were supersaturated with oxygen either by thermal decomposition of 1,4-peroxy-1,4-dimethylnaphthalene or by pressurizing molecular oxygen above the sample solution. The linear relationship between the Lorentzian component of the line width and the O(2) concentration was prove...

When prairie dogs (Cynomys ludovicianus) are fed a diet containing cholesterol, a marked increase in gallbladder mucin secretion parallels the evolution of cholesterol supersaturated bile. Gelation of mucin precedes the precipitation of cholesterol liquid and solid crystals and the development of gallstones. Aspirin given to prairie dogs inhibited mucin hypersecretion and gel accumulation and p...
