Using young adult literature : a classic way to teach English

Students are reading less, and enjoying reading less. Sticking to the same curriculum year after year in the hope that student attitude will suddenly change, that there will be an awakening in the classroom, and students will read the classics with enthusiasm cannot be done. It is a false hope. But there can be an awakening. Using young adult literature in the high school English classroom is the solution. It will give new hope to teachers that as students come to enjoy reading, they will be more apt to, not only read more, but eventually come to read the classics. Teachers must provide that new hope to themselves, their students, their schools, and future generations through the use of young adult literature – indeed, a classic way to teach English

The integral monodromy of hyperelliptic and trielliptic curves

We compute the \integ/\ell and \integ_\ell monodromy of every irreducible component of the moduli spaces of hyperelliptic and trielliptic curves. In particular, we provide a proof that the \integ/\ell monodromy of the moduli space of hyperelliptic curves of genus $g$ is the symplectic group \sp_{2g}(\integ/\ell). We prove that the \integ/\ell monodromy of the moduli space of trielliptic curves with signature $(r,s)$ is the special unitary group \su_{(r,s)}(\integ/\ell\tensor\integ[\zeta_3])

GENETICS AND BIOCHEMISTRY OF DEHALOGENATING ENZYMES

Microorganisms that can utilize halogenated compounds as a growth substrate generally produce enzymes whose function is carbon-halogen bond cleavage. Based on substrate range, reaction type and gene sequences, the dehalogenating enzymes can be classified in different groups, including hydrolytic dehalogenases, glutathione transferases, monooxygenases and hydratases. X-ray crystallographic and biochemical studies have provided detailed mechanistic insight into the action of haloalkane dehalogenase. The essential features are nucleophilic substitution of the halogen by a carboxylate group and the presence of a distinct halogen binding site, formed by tryptophan residues. This review summaries current knowledge on a variety of other dehalogenating enzymes and indicates the existence of a widespread and diverse microbial potential for dechlorination of natural and xenobiotic halogenated compounds

Bistability in a simple fluid network due to viscosity contrast

We study the existence of multiple equilibrium states in a simple fluid network using Newtonian fluids and laminar flow. We demonstrate theoretically the presence of hysteresis and bistability, and we confirm these predictions in an experiment using two miscible fluids of different viscosity--sucrose solution and water. Possible applications include bloodflow, microfluidics, and other network flows governed by similar principles
