| The performance analyses of selective packet dropping policies have usually been performed using homogeneous traac sources and under one node scenarios. In this paper we focus our attention not only to heterogeneous sources but also heterogeneous environments. We present simulation results of application level performance for heterogeneous traac sources under three diierent packet dropping sc...

While much attention has been focused on the molecular epidemiology of retroviruses in wild primate populations, the correlated question of the frequency and nature of super-infection events, i.e., the simultaneous infection of the same individual host with several strains of the same virus, has remained largely neglected. In particular, methods possibly allowing the investigation of super-infe...

Object: This paper aims to evaluate the influence of dental implants coated with hydroxyapatite (HA) and implants processed by micro-arc oxidation (MAO) coupling electrophoresis deposition (EPD) on experimental peri-implantitis in Beagle dogs. Methods: The thirty-six implants (diameter 3.3 mm & length 11 mm) were equally divided into three groups. Group A was processed with a plasma-sprayed lay...

The structure of a protein provides insight into its physiological interactions with other components of the cellular soup. Methods that predict putative structures from sequences typically yield multiple, closely-ranked possibilities. A critical component in the process is the model quality assessing program (MQAP), which selects the best candidate from this pool of structures. Here, we presen...

Estrogen has an important function in swine reproduction and growth. A Pvu II restriction enzyme polymorphism has been proven to be an important genetic variation in the estrogen receptor gene (ESR) and may be considered as a candidate gene for use in pig production but there is no data regarding the prevalence of this polymorphism in the Brazilian pig population. We used DNA samples from the f...

Background: Atheroemboli are the rule in any intervention and the leading cause of complications during percutaneous coronary intervention, carotid angioplasty (CAS), and probably after renal angioplasty stenting (RAS), which could explain the renal function deterioration after RAS in 20–30% of the cases. Several series of RAS under protection were reported using current embolic protection devi...

In our prior studies, we synthesized special circuits with evolution matrices featuring degenerate eigenfrequencies and nontrivial Jordan blocks. The degeneracy of this type is sometimes referred to as exceptional point (EPD). Our focus here on the simplest EPDs that are composed only two LC-loops coupled by a gyrator. These circuits, when near an EPD state, can be used for enhanced sensitivity...

Vật liệu graphen oxit (GO) được tổng hợp bằng phương pháp Hummer cải tiến và biến tính với mangan đioxit (MnO2) hóa học để thu vật tổ MnO2/GO. Một số chất đặc trưng của đánh giá phổ hồng ngoại, UV-Vis, hiển vi điện tử quét kết quang tán xạ năng lượng tia X ảnh mapping. Các thông trong di lắng đọng (EPD) như pH, thế phân, thời gian nồng độ clorua natri khối đã nghiên cứu. MnO2/GO có khả loại màu...

In this study, we investigated the deposition kinetics of polyvinylidene fluoride copolymerized with trifluoroethylene (P(VDF-TrFE)) particles on stainless steel substrates during the electrophoretic deposition (EPD) process. The effect of applied voltage and deposition time on the structure and ferroelectric property of the P(VDF-TrFE) films was studied in detail. A method of repeated EPD and ...
