Improvement on Adhesion Properties of Insert Injection Molding Composites: Effect of Inserted Parts, Adhesive Lengths and Injection Conditions  [PDF]
Badin Pinpathomrat, Hiroyuki Hamada
Open Journal of Composite Materials (OJCM) , 2017, DOI: 10.4236/ojcm.2017.74013
Abstract: The focus of this project is on the insert injection molding process, developed for merging similar or different materials by molding injected melted polymer around an inserted part and injecting in the molded cavity of the conventional injection molding machine. This method is ideal for attaching automotive parts without having to use bolts or adhesives. Glass fiber-reinforced polypropylene (GF/PP) with various adhesive lengths of 0 and 5 mm was prepared as the inserted part and injected to the mold. The effects of the inserted parts, adhesive lengths, and injection conditions on the adhesive properties were investigated. The strength of the interfacial adhesive between the insert and the injected polymer was measured by using an Intron Universal Testing machine. The effects of the material in the inserted and injected parts were analyzed. It was found that by increasing the binding area of the adhesive interface, the barrel temperature, and the mold temperature, the interfacial adhesive strength of the insert injection molded-part was improved in all tested specimens.
On the role of non-uniform stratification and short-wave instabilities in three-layer quasi-geostrophic turbulence
Gualtiero Badin
Physics , 2015, DOI: 10.1063/1.4895590
Abstract: The role of short-wave instabilities on geostrophic turbulence is studied in a simplified model consisting of three layers in the quasi-geostrophic approximation. The linear stability analysis shows that short-wave instabilities are created by the interplay between the shear in the upper and the lower layers. If the stratification is non-uniform, in particular surface intensified, the linear growth rate is larger for short-wave instabilities than for long-wave instabilities and the layers are essentially decoupled, with the small scales growing independently. The fully developed homogeneous turbulence is studied in a number of numerical experiments. Results show that in both the case of equal layer depths and surface intensified stratification an inverse cascade in kinetic energy is observed. The modal kinetic energy spectra for the case with surface intensified stratification show higher energy for higher baroclinic numbers at small scales, due to the decoupling of the layers. As a result, while the case with equal layer depths shows large barotropic instabilities with large scale gradients of potential temperature, the surface intensified stratification is characterized by a transition from surface dynamics, characterized by a patchy distribution of vorticity, to interior dynamics, characterized by vorticity filamentation. The effect of the short-wave instabilities can be seen in the probability distribution functions of the potential vorticity anomaly, which reduces to a Gaussian distribution when the growth rate of the short-wave instabilities is larger than the growth rate for the long-wave instabilities. The surface intensified stratification also alters the vertical structure of the potential vorticity fluxes and shows deviations of the fluxes from a scaling obtained assuming that the turbulence acts as a downgradient diffusion.

Abstract: uximab in the treatment of B-cell non-Hodgkin lymphoma, focus on outcomes and comparative effectiveness Review (4492) Total Article Views Authors: Firas Badin, John Hayslip Published Date April 2010 Volume 2010:2 Pages 37 - 45 DOI: http://dx.doi.org/10.2147/CEOR.S4221 Firas Badin, John Hayslip University of Kentucky, Markey Cancer Center, Lexington, KY, USA Abstract: Rituximab is an important and well established component in the treatment of many patients with B-cell non-Hodgkin lymphoma. In this paper we review recent clinical trials investigating the addition of rituximab to standard chemotherapy regimens for treatment of patients with diffuse large B cell lymphoma and follicular lymphoma. This report focuses upon treatment efficacy, quality of life, and safety of rituximab or rituximab-containing regimens. More uniquely, we review economic aspects of lymphoma treatments, including the cost of standard chemotherapy regimens with or without rituximab, cost effectiveness of rituximab in both induction and maintenance treatment, and lymphoma’s impacts on patient’s productivity and their caregivers. We conclude that adding rituximab to standard chemotherapy treatment for patients with B-cell non-Hodgkin lymphoma is safe and cost-effective in numerous settings during both induction and maintenance therapies. Despite extensive review of the literature, many important questions have yet to be answered in the rituximab era and these represent important directions for future study.
Naturalizing Alterity: Edward Maturin’s Bianca: A Tale of Erin and Italy and Lady Morgan's Italy
Donatella Abbate Badin
Studi Irlandesi : a Journal of Irish Studies , 2011,
Abstract: In the nineteenth century the image of Italy appealed also to Irish Romantic writers. But the way in which they naturalized the Italian alterity is quite ambivalent. On the one hand they filtered their images of the southern country through their relationship with England and thus ended up mirroring stereotypes common to the English-speaking world, and on the other hand they established a special, personal relationship with it shaped by their ideological and cultural differences from the British. This essay tackles the representations of Italy in two texts, namely Edward Maturin’s Bianca: A Tale of Erin and Italy, published in 1852, and in the earlier Italy (1821) by Lady Morgan. Both these works show that at that time there was a certain awareness, in Ireland, of the special historical and political conditions of Italy and of possible similarities with Ireland. Italy, oppressed by foreign domination yet aspiring to freedom, became a yardstick for gauging issues of subjugation, injustice, and national identity and invited sympathy from the citizens of a colonized country. Therefore, Italy was perceived as a mirror in which to reflect the Irish identity torn by aspirations which were hard to confess publicly or even to oneself. Keywords: Maturin, Lady Morgan, alterity, Italy, Irish Romanticism

Anomalous Resistance in Critical Ionization Velocity Phenomena
V. I. Badin
Physics , 2001,
Abstract: To describe the generation of the electric field by a discontinuity of the Hall current, an equation of the third order is obtained using the electric charge conservation and Ohm laws. The solutions of this equation are used to model the electric impulses detected in experiments aimed to verify Alfven's hypothesis on the critical ionization velocity at collisions of neutral gas with magnetized plasma. A quantitative agreement with experiment is attained and the main features of measured signals are modeled under an assumption on the strong anomalous resistance behind the discontinuity. Apparently, the anomalous resistance occurs due to trapping the current carriers by a small-scaled modulation of the electric field.
On the Representation of Dissipation as a Symplectic Process, with Application to sliding Friction and 2D viscous Fluid Mechanics
Richard Blender,Gualtiero Badin
Physics , 2015,
Abstract: Dissipation can be represented in Hamiltonian mechanics in an extended phase space, as suggested by [Morse and Feshbach, Methods of Theoretical Physics, McGraw-Hill, New York, 1953, Vol I, pp. 298-299]. The method uses an unphysical auxiliary variable which represents the excitation of unresolved dynamics (subscales) and a Hamiltonian for the interaction between the resolved dynamics and the auxiliary variable. This method is here applied both to a finite dimensional system, where dissipation takes the form of friction, and to an infinite dimensional system, namely viscous dissipation (including hyper-viscosity) in a two-dimensional fluid, for which the dynamics is non-canonical. We derive a metriplectic representation and suggest a measure for the entropy of the system.
Hydrodynamic Nambu Brackets derived by Geometric Constraints
Richard Blender,Gualtiero Badin
Physics , 2015, DOI: 10.1088/1751-8113/48/10/105501
Abstract: A geometric approach to derive the Nambu brackets for ideal two-dimensional (2D) hydrodynamics is suggested. The derivation is based on two-forms with vanishing integrals in a periodic domain, and with resulting dynamics constrained by an orthogonality condition. As a result, 2D hydrodynamics with vorticity as dynamic variable emerges as a generic model, with conservation laws which can be interpreted as enstrophy and energy functionals. Generalized forms like surface quasi-geostrophy and fractional Poisson equations for the stream-function are also included as results from the derivation. The formalism is extended to a hydrodynamic system coupled to a second degree of freedom, with the Rayleigh-B\'{e}nard convection as an example. This system is reformulated in terms of constitutive conservation laws with two additive brackets which represent individual processes: a first representing inviscid 2D hydrodynamics, and a second representing the coupling between hydrodynamics and thermodynamics. The results can be used for the formulation of conservative numerical algorithms that can be employed, for example, for the study of fronts and singularities.
