Rocas Atoll is the only one of its kind in the South Atlantic—and the first Brazilian marine biological reserve. This is the first report about the ascidians from Rocas. A total of 12 species were found, 5 of them not hitherto described:Ascidia viridina sp. nov.,Didemnum rochai sp. nov., Leptoclinides crocotulus sp. nov., Polysyncraton maurizeliae sp. nov., and Trididemnum rocasensis sp. nov. O...

The ascidian fauna of the Pacific coast of Panama is poorly known and only recently four species in the family Ascidiidae were reported on. Ascidia is the only known genus of Ascidiidae in Pacific Panama waters. In the present research, we describe a new species, Ascidia sideralis sp. nov., and we document the new occurrence of A. cf. gemmata and A. cf. liberata (both previously known to the We...

OBJECTIVES To validate an instrument to assess quality of mobile emergency pre-hospital care. METHOD A methodological study where 20 professionals gave their opinions on the items of the proposed instrument. The analysis was performed using Kappa test (K) and Content Validity Index (CVI), considering K> 0.80 and CVI ≥ 0.80. RESULTS Three items were excluded from the instrument: Professional...

This study investigates a critical issue for E-retailers: balancing their spending on information technology and advertising. E-retailers often over-spend on advertisement to attract customers, but fail to support them due to inadequate spending on technology infrastructure. In this study we show that the demand generation and site capacity must be synchronized. E-retailers should place a highe...

Background: There are different street substance users' communities (SSUCs). Typology of SSUCs in Tehran, Iran was approached in this qualitative study.Methods: Using content analysis and saturation principles, 22 street-outreach workers were recruited and interviewed. Data were analyzed using open, axial, and selective coding.Findings: Three types of SSUCs were identified. SSUCs were different...

In order to form a collaborative operation between village power grid and the end users, two-stage management strategy is proposed where residential photovoltaic systems have been linked distribution network in rural area. At stage one, regulation method considering active reactive formed with purpose of maintaining within security domain operation; at two, maximize benefits both its costumers,...

In this paper we address an order processing optimization problem known as minimization of open stacks (MOSP). We present an integer programming model, based on the existence of a perfect elimination scheme in interval graphs, which finds an optimal sequence for the costumers orders.
