to evaluate the germination traits and mechanical damage of soybean seed during processing stages, anexperiment was conducted in a factorial experiment based on completely randomized design with 18treatments at mazandaran province (sari) in 2009-10. the experiment factors included different seedprocessing stages (before cleaning, after elevator, after pre cleaning, after cleaning, after drying ...

The outstanding thermal, optical, electrical and mechanical properties of molybdenum disolphide (MoS2) heterostructures make them exceptional candidates for an extensive area applications. Nevertheless, despite considerable technological academic interest, there is presently a few information regarding the these novel two-dimensional (2D) materials in presence defects. In this manuscript, we pe...

This study focuses on the influence of natural and artificially induced cracks durability concrete reinforced with carbon nanotubes (CNT). Pre-cracked mixes, unreinforced or 0.1% CNT, are characterized in terms capillary absorption, carbonation, chloride penetration resistance, compared to uncracked reference concrete. The mechanical strength properties were improved CNT-reinforced concrete, wi...

Although research has shown a considerable influence of the pre-cracking phenomenon on steel-congested concrete members, only normal (NC) been considered in literature. The intention this paper is thus to study effect bond response pre-cracked NC with different slump flow values and self-consolidating (SCC). Initial crack widths ranging from 0.0 0.5 mm are studied. Results show that initial lar...

A multiscale (micro-macro) approach is proposed for the establishment of the full thermal and induced stress fields in cracked composites that are subjected to heat flow. Both the temperature and stresses distributions are determined by the solution of a boundary value problem with one-way coupling. In the micro level and for combined thermomechanical loading, a micromechanical analysis is empl...

In this paper, several transversely cracked RC beams, self-anchored in a three-point bending mode, were prepared and subjected to NaCl solution drying–wetting cycles. Based on two experimental results obtained after 15 and 30 cycles, respectively, the profiles of free chloride concentration at different sections of sound and cracked concretes were presented and analyzed. The depth of surface co...

PURPOSE To provide an overview of the clinical features, diagnosis, classification and management of cracked teeth which may be a diagnostic challenge in clinical practice. RESULTS Cracks may initiate from coronal tooth structure or from within the root and affect healthy or root treated teeth. There are many terminologies and classifications in the literature for cracked teeth that can be as...

BACKGROUND To assess the prevalence and factors associated with the occurrence of cracked nipples in the first month postpartum. METHODS This was a cross-sectional study nested in a cohort of mothers living in Feira de Santana, state of Bahia, northeastern Brazil. Data from 1,243 mother-child dyads assessed both at the maternity ward and 30 days after delivery were analyzed. The association b...
