Abstract During the differentiation of erythroid cells, a vast program of maturation takes place, leading to decay or elimination of organelles, including the nucleus, mitochondria, ribosomes, lysosomes, endoplasmic reticulum and Golgi apparatus. During the last step of red cell maturation, remaining organelles, primarily mitochondria and ribosomes but also vestiges of others are finally cleared from the cell. This cleaning session also affects specific proteins that are partially or entirely removed from the cell surface. The interplay of the various events and their causal relationships are approached here. More >

Abstract Environmental contamination with some metalloids and heavy metals (M/HM) raises concern due to well known adverse effects on health. Among these pollutants, chromium VI (Cr VI), cadmium (Cd) and arsenic (As) are frequently present as a result of natural sources or due to industrial activities. They are able to easily enter the organism and negatively affect many organs and systems. In vivo (exposure to Cr VI, Cd or As through drinking water) and in vitro experiments (primary pituitary cell cultures) were performed in male Wistar rats to address their actions on hypothalamus-pituitary axis. All the M/HM accumulated in hypothalamus and… More >

Abstract In order to investigate the burning characteristics of a 0# diesel and 3# jet fuel, a small-scale experimental bench mainly composed of a cone calorimeter was arranged. The heat release and burning rates were investigated changing the external irradiance in order to clarify the triadic relationship among these quantities. The effective heat of combustion of 0# diesel and 3# jet fuel were 38.89 MJ/kg and 43.15 MJ/kg, respectively, with the corresponding combustion efficiencies being 96.78% and 99.60% (the effective peak heat of combustion being 1.665 times the mean value for both types of fuel). According to our experimental results, the… More >

Abstract This paper focuses on the interface energy release rate of elastic multilayered beam subjected to four-point bending. Linear elastic fracture mechanics (LEFM) and extended finite element method (XFEM) are adopted to investigate the interface fracture of composite beams. Numerical results obtained from simulations not only verify the accuracy of closed-form solutions for the steady-state interface energy release rate, but also provide the evolution history of interface energy release rate under different crack length. In addition, non-dimensional parametric analyses for interface fracture energy release rate are carried out for the discussion of effects of crack length ratio, elastic modulus ratio, and… More >

Abstract The compliance equation is used to calculate the energy release rate for angle ply laminated double cantilever composite beam specimen. Instead of the traditional approach of a beam on an elastic foundation, a second order shear thickness deformation beam theory (SSTDBT) has been considered. More >

Abstract A numerical method based on the virtual crack closure technique (VCCT) [Rybicki and Kanninen (1977)] and in conjunction with the finite element (FE) method is presented to compute strain energy release rates for cracks that kink. The method partitions the strain energy release rate and provides an efficient means to compute values of the mode I (G_I) and mode II (G_II) energy release rate at the tip of a kinking crack. The solution procedure is shown to be computationally efficient and operationally simple, involving only the nodal forces and displacements near the crack tip. Example problems with kinking cracks in… More >

Abstract Double cantilever beam tests were used to measure the energy release rates of linear vibrational welded moso bamboo joints. The influence of the length of the preserved cracks, the different combinations of the inner and outer bamboo surfaces and the moisture content is studied herein. The experimental compliance method, which is based on linear elastic fracture mechanics and has been shown to be an ideal method, was used to analyze data with the power equation. The results show that the preserved initial crack length does not have a significant effect on the final measured energy release rate, while the moso… More >

Abstract Efforts to improve crop yields with efficient use of fertilizers are needed to guarantee global food security. Enhanced slow-release fertilizer systems (SRFs) encapsulated in biodegradable matrices are being developed to address this global concern. From a wide range of strategies for SRFs development, we explored a nature-inspired solution based on the plant cuticle model and its function as a membrane for water and nutrient transport control. Here, Candelilla wax, extracted from Candelilla wild plants (Euphorbia antisyphilitica), is studied as a renewable slow-release matrix for fertilizers encapsulated by a modified spray chilling process. From this process, microencapsulates containing 40 wt% of… More >

Abstract This work aims to analyze the effects of cold atmospheric air plasma treatment of antimicrobial chitosan film with different levels of thymol. Optical characterization of the dielectric barrier discharge showed the generation of reactive nitrogen and oxygen species by the system. A significant increase (p < 0.05) in the surface roughness was observed after cold plasma treatment of the films. No significant difference (p > 0.05) was observed in the thermal profile of the plasma-treated films. A significant increase (p < 0.05) in the thymol diffusion coefficient was observed after the plasma treatment for all the active films. More >
