Trees critically affect the functioning of savanna ecosystems through their effects on nutrient cycling, water availability, and patterns of space use by wildlife. Therefore, whatever factors influence successful recruitment of tree seedlings are important filters controlling savanna ecosystem function. In African savannas, large mammals have been considered the most important agents of mortali...

Several agronomic benefits can result from fall seeding of canola (Brassica spp.), but extensive research data are lacking on the potential impact of this practice on infestations of root maggots (Delia spp.) (Diptera: Anthomyiidae), which are major pests of the crop in western Canada. Field experiments making up 13 location by year combinations were conducted in central Alberta, Canada, from 1...

OBJECTIVE The purpose of this experimental study was to evaluate the efficacy of carvacrol (CVR) and pomegranate (PMG) against methotrexate (MTX)-induced intestinal damage using histopathological and immunohistochemical techniques. METHODS Thirty-two male Sprague-Dawley rats, weighing 195-250 g, were divided into four groups: control, MTX treatment alone, MTX plus CVR and MTX plus PMG. A sing...

To investigate the effects of silicon on the growth characteristics and the reduction of the powdery mildew damage to Zinnia (Zinnia elegans Jacq. ʻMagellanʼ), an experiment was carried out as a factorial experiment in the form of a randomized complete block design with two factors including eight treatments and three replications. The first factor included silicon concentrations at four levels...

Concrete is a quasi-brittle material and shows different behavior in compression tension. It elastic at initial stage damage-plasticity beyond limit. Therefore, development of model concrete complex phenomenon. In this study, damage plasticity theory has been described under experiment on cylinder considering uni-axial loading interpreted with analytical data calculated using CEB-FIP code equat...

The relationship between the macroscopic mechanical properties of lightweight aggregate concrete and its microstructure is a hot topic in discipline materials. It very meaningful to provide an efficient numerical analysis method conduct meso-level analysis. This study proposes automatic dissection algorithm adapts calculation program base force element non-linear damage In simulation, three gro...

In narrative discourse, explanation can be considered abductive reasoning, described as a creative type of reasoning which generates new ideas, and prediction can be considered logical deductive reasoning. Given the well-known associations with hemisphere processing and reasoning associations, it would be expected that patients with left hemisphere brain damage would exhibit more evidence of ex...

We recorded the damage that wild bearded capuchin monkeys (Sapajus libidinosus) caused to a sandstone anvil during pounding stone tool use, in an experimental setting. The anvil was undamaged when set up at the Fazenda Boa Vista (FBV) field laboratory in Piauí, Brazil, and subsequently the monkeys indirectly created a series of pits and destroyed the anvil surface by cracking palm nuts on it. W...

The objective of this study was to examine the effect of reactive oxygen species (ROS) and cryopreservation on DNA fragmentation of equine spermatozoa. In experiment 1, equine spermatozoa were incubated (1 hour, 38 degrees C) according to the following treatments: 1) sperm alone; 2) sperm + xanthine (X, 0.3 mM)-xanthine oxidase (XO, 0.025 U/mL); 3) sperm + X (0.6 mM)-XO (0.05 U/mL); and 4) sper...

Methyl parathion (MP) is an organophosphate pesticide used in agriculture, although quite often illegally used indoors to contain insects. The present study was planned to investigate the effects of MP on rat testis. Adult male Wistar rats (13-14 weeks) were treated with MP as follows. Experiment 1-0, 1.75, 3.5 or 7 mg/kg i.p. for 5 days and sacrificed on Day 14; experiment 2 and 3- 0, 0.5, or ...
