The production of a new class microfluidic devices built from thermoplastic materials has recently aroused interest in high-volume and cost-effective fabrication sensing devices. During device formation, the bonding two slides, one containing microchannels another used as non-modified capping layer, is generally performed at high temperature, pressure, and/or employing organic solvents. Such pr...

Abstract Adhesive bonding of CFRP is one major approach to join this class compound materials with other components, e.g., metals. The necessity clean parts after fabrication and generate a bond-ready interface without damaging the implemented fibers demands gentle highly reproducible surface treatment. Lasers operating in UV region are promising technique for that topic. Yet, factors influenci...

Present work focuses on frost accretion in a spine-finned inverted-V tube array evaporator. An experimental evaluation was performed using standard issue, vertical top-mount, 18 cubic feet, 0.5 m 3 , refrigerator. Evaporator temperature distribution, inner airflow velocity, and relative humidity were measured to account for convective phenomena influencing distribution. Frost formation the surf...

Mapping river beds to identify water and sandbars is a crucial task for understanding the morphology hydrodynamics of rivers their ecological conditions. The main difficulties this so far have been limitations conventional approaches, which are generally costly (e.g., equipment, time- human resource-demanding) poor flexibility deal with all Currently, alternative approaches rely on remote sensi...

Objective: To point out the nature of land in Brazil from duration Law Land 1850, passing fazem parte acho que faz partethrough Statute 1964, to Federal Constitution 1988. The issue is represented by following question: What legal Brazil? Theoretical framework: This research based on historical approach Smith (1990) and Martins (2015) aiming understand social transformation land. In scope under...

The immediate precursors of antibody molecules, the heavy (H) and light (L) peptide chains of the immunoglobulins, combine with each other by means of disulfide bonds formed by dehydrogenation of their cysteine residues. In the absence of an antigen this process yields the heterogeneous mixture of normal immunoglobulins. Antigens or their processed derivatives (Ag) interfere with this stochasti...

Fidelity and selectivity of DNA polymerases are critical determinants for the biology of life, as well as important tools for biotechnological applications. DNA polymerases catalyze the formation of DNA strands by adding deoxynucleotides to a primer, which is complementarily bound to a template. To ensure the integrity of the genome, DNA polymerases select the correct nucleotide and further ext...

The study addresses the effect of thermal treatment on the internal structure of polyelectrolyte multilayers (PEMs). In order to get insight into the internal structure of PEMs, Neutron Reflectometry (NR) was used. PEMs with a deuterated inner block towards the substrate and a non-deuterated outer block were prepared and measured in 1% RH and in D2O before and after a thermal treatment. Complem...

The present study investigated whether the complementarity principle (mutual interactive behaviors are opposite on control and similar on affiliation) applies to teacher-child interactions within the kindergarten classroom. Furthermore, it was examined whether interactive behaviors and complementarity depended on children's externalizing and internalizing behaviors, interaction time, and intera...

Classification of the relationship between electronic structures and biological activities of endocrine disruptors (so-called environmental hormones) was attempted using the parameters of absolute hardness (eta), absolute electronegativity (chi), and global softness (S), approximately defined as eta=1/2(epsilonLUMO-epsilonHOMO), chi=-1/2(epsilonHOMO+ epsilonLUMO), and S=1/eta, respectively, bas...
