This article describes a systematic literature review on whether, how, and when to perform preoperative hair removal. By searching electronic databases and reference lists of relevant articles, team members identified 20 clinical studies that deal with preoperative hair removal. No strong evidence was found to advocate against preoperative hair removal. Furthermore, there was strong evidence to...

Plant species assemblages, communities or regional floras might be termed 'saturated' when additional immigrant species are unsuccessful at establishing due to competitive exclusion or other inter-specific interactions, or when the immigration of species is off-set by extirpation of species. This is clearly not the case for state, regional or national floras in the USA where colonization (i.e. ...

We are in a state of evolution in long-term hair removal. Safe and effective technology is now available. Lasers will always become smaller, faster, and perhaps more effective. For those interested in offering this procedure, evidence indicates that we are beyond the experimental phase. The treating physician should carefully review current available technology and receive proper training speci...

Coordination chemistry allows the synthesis of new molecules which show cooperative magnetic phenomena, behaving like magnets. Two main ways of synthesizing these systems have been developed: a) low-dimensional complexes (1-D or 2-D) which are linked in the crystal net and so give ferromagnetic long-range order and b) isolated molecules with high-spin ground state and strong anisotropy, which h...

One of the most promising applications for molecules built from paramagnetic metal ions is low temperature magnetic refrigeration.[1] Indeed recent studies have suggested that molecular coolers can outperform any conventionally-employed solid-state refrigerant material by orders of magnitude.[2] In order to do so, molecules must possess a combination of a large spin ground state (S), with negli...

The structure of poplar plastocyanin in the reduced (CuI) state has been determined and refined, using counter data recorded from crystals at pH 3.8, 4.4, 5.1, 5.9, 7.0 and 7.8 (resolution 1.9 A, 1.9 A, 2.05 A, 1.7 A, 1.8 A and 2.15 A; the final residual R value was 0.15, 0.15, 0.16, 0.17, 0.16 and 0.15, respectively). The molecular and crystal structure of the protein is substantially the same...

this study investigates removing ash and pyrite sulphur from bitumen by column flotation process. central composite design (ccd) of response surface methodology (rsm) was applied for modeling and optimization of the percentage of ash and pyrite sulphur removal from bitumen. the effects of five parameters namely the amounts of collector and frother agents, particle size, wash water rate and feed...

2-Methylmercaptobenzohydroxamic acid (mmbHA) has been synthesized and used to form {CuIICl2(MeOH)[12-MCCu(II)N(mmbHA)-4]}2 ⋅ 4MeOH (1) {CuII(μ2-ClO4)(MeOH)2(py)4[12-MCCu(II)N(mmbHA)-4]}ClO4 (2), a copper(II) based double-decker discrete metallacrown (MC) system, respectively. While 1 forms in the absence of coordinating co-ligand, presence pyridine (Py) leads change coordination mode mmbHA MC 2...

A mixed-valent, one-dimensional Cu(I/II) coordination polymer with the formula [CuII{CuI3(Hmpba)(mpba)2}DMF] ⋅ ∼3DMF was obtained bifunctional ligand 4-(3,5-dimethyl-1H-pyrazol-4-yl)benzoic acid (H2mpba) in N,N-dimethylformamide (DMF) via solvothermal reaction. The compound exhibits a trinuclear {CuI3(Hmpba)(mpba)2}2− metallo-linker softer Cu(I) linearly-coordinated by pyrazolate nitrogen donor...
