A dinuclear zinc complex with (E)-4-dimethyl­amino-N′-(2-hy­droxy­benzyl­idene)benzohydrazide

The title compound, bis­[μ-(E)-2-({2-[4-(dimethyl­amino)­benzo­yl]hydrazinyl­idene}meth­yl)phenolato]bis­[formato­zinc], [Zn2(C16H16N3O2)2(CHO2)2], is a dinuclear ZnII complex containing two ZnII cations, two monovalent anions of a Schiff base ligand, 4-dimethyl­amino-N′-(2-hy­droxy­benzyl­idene)benzohydrazide (L), and two formate ions. Each ZnII atom chelates with the hy­droxy O atom of salicyl­aldehyde, the imine N atom, the carbonyl O atom, the formate carboxyl­ate O atom and the hy­droxy O atom of the salicyl­aldehyde moiety in a symmetry-related unit. The five-coordinate ZnII atoms form a dimeric centrosymmetric unit with a central parallelepiped Zn2O2 core and parallel faces derived from the Schiff base ligands. The crystal packing is stabilized by inter­molecular N—H⋯O hydrogen bonds between the amide N atom and the formate carboxyl­ate O atom

A Critical Review on the Structural Health Monitoring Methods of the Composite Wind Turbine Blades

With increasing turbine size, monitoring of blades becomes increasingly im-portant, in order to prevent catastrophic damages and unnecessary mainte-nance, minimize the downtime and labor cost and improving the safety is-sues and reliability. The present work provides a review and classification of various structural health monitoring (SHM) methods as strain measurement utilizing optical fiber sensors and Fiber Bragg Gratings (FBG’s), active/ pas-sive acoustic emission method, vibration‒based method, thermal imaging method and ultrasonic methods, based on the recent investigations and prom-ising novel techniques. Since accuracy, comprehensiveness and cost-effectiveness are the fundamental parameters in selecting the SHM method, a systematically summarized investigation encompassing methods capabilities/ limitations and sensors types, is needed. Furthermore, the damages which are included in the present work are fiber breakage, matrix cracking, delamina-tion, fiber debonding, crack opening at leading/ trailing edge and ice accre-tion. Taking into account the types of the sensors relevant to different SHM methods, the advantages/ capabilities and disadvantages/ limitations of repre-sented methods are nominated and analyzed

Effects of conversion of native cerrado vegetation to pasture on soil hydro-physical properties, evapotranspiration and streamflow on the Amazonian agricultural frontier

Understanding the impacts of land-use change on landscape-hydrological dynamics is one of the main challenges in the Northern Brazilian Cerrado biome, where the Amazon agricultural frontier is located. Motivated by the gap in literature assessing these impacts, we characterized the soil hydro-physical properties and quantified surface water fluxes from catchments under contrasting land-use in this region. We used data from field measurements in two headwater micro-catchments with similar physical characteristics and different land use, i.e. cerrado sensu stricto vegetation and pasture for extensive cattle ranching. We determined hydraulic and physical properties of the soils, applied ground-based remote sensing techniques to estimate evapotranspiration, and monitored streamflow from October 2012 to September 2014. Our results show significant differences in soil hydro-physical properties between the catchments, with greater bulk density and smaller total porosity in the pasture catchment. We found that evapotranspiration is smaller in the pasture (639 ± 31% mm yr-1) than in the cerrado catchment (1,004 ± 24% mm yr-1), and that streamflow from the pasture catchment is greater with runoff coefficients of 0.40 for the pasture and 0.27 for the cerrado catchment. Overall, our results confirm that conversion of cerrado vegetation to pasture causes soil hydro-physical properties deterioration, reduction in evapotranspiration reduction, and increased streamflow
