Vari, Richard P. A Phylogenetic Study of the Neotropical Characiform Family Curimatidae (Pisces: Ostariophysi). Smithsonian Contributions to Zoology, number 471, 71 pages, 45 figures, 3 tables, 1989.—Osteology and soft anatomy of the species of Curimatidae were studied to examine the hypothesis that the family is monophyletic, and to advance a hypothesis of phylogenetic relationships within the...

All generators of the optimal algebra associated with a generalization Endem-Fowler equation are showed; some them allow to give invariant solutions. Variational symmetries and respective conservation laws also showed. Finally, representation Lie symmetry is showed by groups matrices.

An increasing number of scholars are using longitudinal social network data to try to obtain estimates of peer or social influence effects. These data may provide additional statistical leverage, but they can introduce new inferential problems. In particular, while the confounding effects of homophily in friendship formation are widely appreciated, homophily in friendship retention may also con...

Pulmonary TB is a disease caused by Mycobacterium tuberculosis which attacks the respiratory system and often decreases SPO2. Interventions that can be done to reduce shortness of breath increase SPO2 are giving semi-fowler position. To determine effectiveness semi-Fowler's position on increasing breathing patterns in pulmonary patients. Research design literature review. Journal criteria were ...

The present work aims to throw light on the effects of arcing in air on the surface state of contact pastilles made of silvernickel Ag-Ni (60/40). Also, the photoelectric emission from these electrical contacts has been investigated in the spectral range of 196256 nm. In order to study the effects of arcing on the EWF, the metallic samples were subjected to electrical arcs in air, at atmospheri...

We consider a class of second-order Emden-Fowler equations with positive and nonpositve neutral coefficients. By using the Riccati transformation and inequalities, several oscillation and asymptotic results are established. Some examples are given to illustrate the main results.

In this article we consider the existence and uniqueness of local weak solutions to the Emden-Fowler type wave equation tutt − uxx = |u|p−1u in [1, T ]× (a, b) with initial-boundary value conditions in a finite time interval.

We appreciate the thoughtful comments from Dr. Jack Fowler on our recent manuscript of an estimation of radiobiological parameters for head and neck cancer (HNC) and the clinical implications [1]. [...].
