面对比200艘满载的航空母舰还要重的马尾藻,墨西哥人选择勇敢"宣战"。经过几年时间的努力,他们成功夺得了主动权。然而,这场战斗对于墨西哥人来说,仅仅只是开始……早在2010年4月,本刊就介绍了亚洲鲤鱼"入侵"美利坚的事件。当时因其前所未有的扩张速度,使它成为世界上物种泛滥的典型案例。2010年1月初,美国国会将一份需耗资7850万美元的计划书摆在了时任总统奥巴马的椭圆形办公桌上。计划书罗列出一系列详尽的围堵措施,若是被不知情的人看见,还以为发生了越狱事件。

We present the findings of spin-dependent single-hole and pair-hole transport in plane and across the p-type high mobility silicon quantum wells (Si-QW), 2 nm, confined by the superconductor δ-barriers on the n-type Si (100) surface. The oscillations of the conductance in normal state and the zero-resistance supercurrent in superconductor state as a function of the top gate voltage are found to be correlated by on- and off-resonance tuning the two-dimensional levels of holes in Si-QW with the Fermi energy in the superconductor δ-barriers. The SIMS and STM studies have shown that the δ-barriers heavily doped with boron, 5 × 1021 cm–3, represent really alternating arrays of silicon empty and doped dots, with dimensions restricted to 2 nm. This concentration of boron seems to indicate that each doped dot located between empty dots contains two impurity atoms of boron. The EPR studies show that these boron pairs are the trigonal dipole centres, B+ - B–, that contain the pairs of holes, which result from the negative -U reconstruction of the shallow boron acceptors, 2B0 => B+ - B–. The electrical resistivity, magnetic susceptibility and specific heat measurements demonstrate that the high density of holes in the Si-QW (> 1011 cm–2) gives rise to the high temperature superconductor properties for the δ-barriers. The value of the superconductor energy gap obtained is in a good agreement with the data derived from the oscillations of the conductance in normal state and of the zero-resistance supercurrent in superconductor state as a function of the bias voltage. These oscillations appear to be correlated by on- and off-resonance tuning the two-dimensional subbands of holes with the Fermi energy in the superconductor δ-barriers. Finally, the proximity effect in the S-Si-QW-S structure is revealed by the findings of the quantization of the supercurrent and the multiple Andreev reflection (MAR) observed both across and along the Si-QW plane thereby identifying the spin transis

We present the first findings of the new electrically- and optically-detected magnetic resonance technique [ED electron spin resonance (EDESR) and (ODMR)] which reveal single point defects in the ultra-narrow silicon quantum wells (Si-QW) confined by the superconductor δ-barriers. This technique allows the ESR identification without the application of the external cavity as well as a high frequency source and recorder, with measuring the only magnetoresistance (EDESR) and transmission (ODMR) spectra within frameworks of the excitonic normal-mode coupling (NMC) caused by the microcavities embedded in the Si-QW plane. The new resonant positive magnetoresistance data are interpreted here in terms of the interference transition in the diffusive transport of free holes respectively between the weak antilocalization regime in the region far from the ESR of a paramagnetic point defect located inside or near the conductive channel and the weak localization regime in the nearest region of the ESR of that defect.

Environment chemical pollution can be persistent, and even virtually irremovable. For some chemicals in the workplace environment reliably safe low exposure levels are technically unattainable or presumably nonexistent. As a supplement to decreasing harmful exposures to as low levels as possible, the “biological prophylaxis” aims at enhancing host’s protective mechanisms. During over 30 years in animal experiments modeling isolated or combined chronic or subchronic exposures to silica, asbestos, monazite, lead, chromium, arsenic, manganese, nickel, vanadium, nanosilver, nanocopper, formaldehyde, phenol, naphthalene, benzo(a)pyrene we tested so-called “bioprophylatic complexes” (BPCs) comprising innocuous substances with theoretically expected beneficial influence on the toxicokinetics and/or toxicodynamics of those toxics. The BPCs proved protectively effective in animal experiments were then subjected to controlled field trials on restricted groups of volunteers. Once the effectiveness and safety of a BPC was established, it was recommended for practical use, first of all, in the most vulnerable population groups (children, pregnant women) and in the most harmful occupations. At each stage of this work the effectiveness of the bioprophylactic approach to chemical risks management was successfully demonstrated. The BPCs tested up to now proved capable of mitigating systemic toxicity, cytotoxicity, fibrogenicity, and mutagenicity of the above-listed chemicals.
