Complete 24 h energy and nitrogen balances were measured for fifteen subjects at three levels of energy intake and for two other subjects at two levels of intake. At each level, the fifteen subjects ate diets consisting of fifteen to twenty separate foods for 7 or 8 d. Faeces and urine were collected for the final 4 d. Respiratory gas exchange was measured during the final 72 h while the subjec...

Interspecific interactions between insect herbivores predominantly involve asymmetric competition. By contrast, facilitation, whereby herbivory by one insect benefits another via induced plant susceptibility, is uncommon. Positive reciprocal interactions between insect herbivores are even rarer. Here, we reveal a novel case of reciprocal feeding facilitation between above-ground aphids (Amphoro...

Recent advances in the study of electrodisintegration of 3 He are presented and discussed. The pair-correlated hyperspherical harmonics method is used to calculate the initial and final state wave functions , with a realistic Hamiltonian consisting of the Argonne v18 two-nucleon and Urbana IX three-nucleon interactions. The model for the nuclear current and charge operators retains one-and many...

  Abstract   Background: Gastric cancer is the second most common cancer and also the second   cancer related death all over the world. In recent years recorded data for tumor   has shown a rise in the incidence of gastric cancer in young individuals. The present   study was designed to compare some of the epidemiologic characteristics of individuals   suffering from gastric cancer aged below a...

Low-order relativistic perturbation-theory calculations are carried out for dielectronic recombination cross sections for C3+ above and below the ionization threshold. Cross-sectional calculations are made for the 38 levels of the 1s22p4l resonance configurations that lie within ±1.0 eV of the ionization threshold. The below-threshold calculations predict an unobserved strong resonance feature ...

Why do people vary in their views of human nature and their visions of the good society? Why do many people categorize themselves as “liberal,” “conservative,” “libertarian,” “socialist,” and so on? Some researchers try to answer these questions by starting with people’s self-identifications and then moving “down,” examining traits (such as openness to experience) that underlie and predict endo...

Relational rules such as 'same' or 'different' are mastered by humans and non-human primates and are considered as abstract conceptual thinking as they require relational learning beyond perceptual generalization. Here, we investigated whether an insect, the honeybee (Apis mellifera), can form a conceptual representation of an above/below spatial relationship. In experiment 1, bees were trained...

We present a rewiew and also new possible applications of p-adic numbers to pre-spacetime physics. It is shown that instead of the extension IR → Qp , which is usually implied in padic quantum field theory, it is possible to build a model based on the IR → Qp, where p=n+2 extension and get rid of loop divergences. It is also shown that the concept of mass naturally arises in p-adic models as in...

Parameterized complexity can be viewed as a two-dimensional approach to traditional complexity theory. Rather than measuring the complexity of a problem purely in terms of the input size, we also consider some structural parameter of the input instance, and measure how the complexity of the problem changes as this parameter changes. The analogue of polynomial time tractability is fixed-paramete...

Satellites play a major role in the determination of the rainfall at sea. Researchers at Southampton Oceanography Centre (SOC) have been involved in two projects addressing this task. First they have been instrumental in developing techniques to retrieve rain rate information from the 10+ years of dual-frequency altimeter data. The TOPEX radar measures rainfall via the attenuation it causes, pr...
