His mother wrote “I taught him to read quite early—partly in self-defence, for when he became absorbed in a book he ceased to ask questions.” To prove to him that methane was lighter than air and to demonstrate the effects of breathing methane, his father took him crawling into a mine, asked him to stand up and recite Mark Anthony’s speech from Shakespeare’s Julius Caesar. “Friends, Romans and ...

CHARLES Darwin was gratefully aware of the adFisher and Luca Cavalli-Sforza, but there is scant record vances in microbiology and infectious disease (ID) of their interventions. associated with his contemporaries, Louis Pasteur and In his paper, Haldane recites common knowledge of Robert Koch. Nevertheless, in none of his works does ID and its potential potency as an agent of natural seleche ma...

A paramagnetic method of carbon dioxide analysis enables the simultaneous analysis of carbon dioxide and oxygen to be made at 2-min intervals. The method depends upon observing the change of oxygen concentration in a gas mixture before and after absorbing the carbon dioxide component. The carrier-gas in the experiments reported was nitrogen. The output of the paramagnetic meter was measured bot...

We classify all possible 36 gap-opening instabilities in graphenelike structures in two dimensions, i.e., masses of Dirac Hamiltonian when the spin, valley, and superconducting channels are included. These 36 order parameters break up into 56 possible quintuplets of masses that add in quadrature and hence do not compete and thus can coexist. There is additionally a sixth competing mass, the one...

In this study, kinetics of biological carbon, nitrogen, and phosphorous removal from a synthetic wastewater in an integrated rotating biological contactoractivated sludge system was investigated. The experimental data obtained from varying four significant independent factors viz., hydraulic retention time, chemical oxygen demand for nitrogen to phosphorus ratio, internal recirculation from aer...

Large differences in enzymatic activity are often found between intact cells and extracts. Lacking a better explanation, it has frequently been assumed that the penetration of the substrate is the rate limiting step in the intact cells. The experiments reported here were designed to test several hypotheses which might account for the discrepancy. The 3-galactosidase (lactase) in Escherichia col...

The antiferromagnetic Heisenberg spin chain has been a subject of immense interest since Haldane pointed out that the low-energy physics of integer and half integer spin chains are fundamentally different. With advance in both experiments and numerical techniques, the prediction by Haldane is now generally accepted. More recently, a series of experiments on the family of quasi-one-dimensional m...

Sulphide (H2S, HS- and S2-) is an undesired by-product of biogas production processes. This modelling work in Aquasim was carried out to study three parallel processes related sulphide AD processes: 1) H2S liquid-gas mass transfer; 2) Acid-base equilibrium; 3) oxidation with different electron acceptors; nitrate, oxygen, a biotic anode given potential. Multiplicative Monod (biotic processes) Ne...

We investigate the ground-state phase diagram of a modified spinless Haldane-Hubbard model, with broken threefold rotational symmetry, employing exact diagonalization calculations. The interplay asymmetry, interactions, and topology gives rise to rich diagram. noninteracting limit Hamiltonian exhibits higher-order topological insulator characterized by existence corner modes, in contrast known ...
