Optimum harvesting area of convex and concave polygon field for path planning of robot combine harvester

This paper presents an optimum harvesting area of a convex and concave polygon for the path planning of a robot combine harvester. A convenient optimum harvesting area for a convex and concave polygon is proposed. The notion is that path planning specifically for a robot combine harvester is required to choose the crop field optimum harvesting area; otherwise, crop losses may...

Using reduced representation libraries sequencing methods to identify cpDNA polymorphisms in European beech (Fagus sylvatica L)

Reduced representation genomic libraries (RRLs) are increasingly used to answer diverse questions in evolutionary biology, which remained unresolved otherwise. In the case of European beech (Fagus sylvatica L.), former applications of nuclear and chloroplast genetic markers indicated that most of the beech populations of Central, Eastern, and Northern Europe have a very...

O methohexital sódico (Brevital®) no teste de Wada: relato de dois casos

ABSTRACT INTRODUCTION: The Wada's test is still being frequently used at epilepsy surgery centers in temporal lobectomy candidates to evaluate the extent, quality and lateralization of memory functions, and to estimate residual deficit, since it simulates the effects of the surgery. In Brazil, Amytal® is very difficult to be obtained due to local regulatory barriers. OBJECTIVES...

A separação do Cálcio de Estroncio mediante o emprego de Resina Trocadora de Íons e de Estroncio Radioativo Sr-89

A simple, rapid and efficient method of separation of strontion from calcium can be perfomed by using a solution of 2.5% NH4- EDTA, with pH adjusted to 4.80 to dissolve those cations. After, the solution is passed through a 25-28 ml column of the Amberlite 1R-120 (4+) cation exchange resin. Strontinum is quantitatively retained on the resin, while calcium passes through. After...

El v (verbo ligero) como categoría procedimental

The papers of Leonetti (2001, 2004) and Escandell Vidal and Leonetti (1997) hypothesized that the functional categories (FFCC) proposed in the Minimalist Program of Chomsky (1995, 1998, 1999, 2005) are the procedural categories proposed by Relevance Theory (Sperber and Wilson, [1986] 1995). This is demonstrated convincingly for some of the FFCC, the Determinant and the...

The Brody effect induced by premature ventricular complexes in the ovine heart

The QRS response of the electrocardiogram to bleeding has been a source of interest to the physiologist for more than a century. Studies in the dog, cat and chicken have shown a reduction in QRS amplitude in response to bleeding. This effect has been explained by the so-called Brody effect, in which the intraventricular mass of blood acts as a conducting medium, augmenting radial...

La galaxia poética latinoamericana: 2ª mitad del siglo XX

This article proposes a spatial metaphor of development in Latin American poetry: a galaxy that expands rapidly towards the limits. It also analyzes the strongest centrifugal movements, represented by Residencia en la tierra by Neruda or Diario de muerte by Enrique Lihn. In general, it examines some exemplary decenterings of the poetry of the twentieth century as effected by the...

Capturing the life cycle of false hair products to identify opportunities for remanufacture

The false hair industry represents a case of growing demand and depleting natural resources, in addition to a significant environmental impact of synthetic alternatives. Despite the growth of the false hair industry, there is a lack of research to date regarding the complete life cycle of false hair products. False hair products currently follow a linear life cycle with a cradle...

Assessment of subclinical acute kidney injury after abdominal aortic aneurysm surgery using novel markers: L-FABP and H-FABP

Background: One of the most severe complications of repair surgery for abdominal aortic aneurysms (AAA) is acute kidney injury (AKI). Even small rises in serum creatinine are associated with increased mortality. The aim of this study was to assess the dynamics of AKI after elective AAA surgery using novel markers. Methods: The study group consisted of 22 patients with AAA. We...

Doing public theology in the anthropocene towards life-creating theology

If one presumes that we are today living in the anthropocene, how does this challenge the doing of public theology? What is the calling of a public theologian in the anthropocene? To be able to answer these questions, this article shortly described the anthropocene and then sought to unpack a possible doing of theology in a particular local context, within the time of the...
