Electrospinning offers a powerful route for building one-dimensional (1D) micro/nanostructures, but a common requirement for toxic or corrosive organic solvents during the preparation of precursor solution has limited their large scale synthesis and broad applications. Here we report a facile and low-cost way to prepare 1D porous carbon microfibers by using an electrospun fiber-like natural pro...

This study investigated the copulatory behaviour of the lumbricid earthworm Eisenia fetida (Savigny, 1826) in a natural population, and the uniparental reproduction of E. fetida and E. andrei Bouché 1972, two closely-related species. Sperm transfer occurred in 61 % of the matings observed, of which 88.2 % showed bi-directional sperm transfer, 9.8 % unidirectional sperm transfer and one earthwor...

 The ionizing radiations, through physical and chemical processes, lead to simple and complex single- and double- strand breaks, as well as base lesions to the DNA. In this study, taking into account all the physical and chemical processes involved in the interaction of ionizing radiation with matter, the initial damage induced to DNA was evaluated for 5.7 MeV alpha-rays from Radon 223 isotope....

one way to increase the heat transfer is to use perforated twisted tapes with different hole diameters, which largely improve heat transfer with an increase in the heat transfer area at the constant volume and more mixed flow. in the previous studies, the effect of nanofluids with perforated twisted tapes is less studied. in this work, the performance of water / iron oxide nanofluid in a double...

INTRODUCTION Abdominal cocoon syndrome is characterized by small bowel encapsulation by a fibro-collagenous membrane or "cocoon". It is a rare cause of intestinal obstruction. PRESENTATION OF CASE A 42-year old man presented with sub-acute intestinal obstruction. Intra-operatively, the entire small bowel was found to be encapsulated in a dense fibrous sac. The peritoneal sac was excised, foll...

Predators exert strong top-down pressure on herbivorous insects, but research on how predators affect herbivore fitness often focuses on the more active juvenile and adult life stages while ignoring the pupal or cocoon life stage. Few studies have investigated predation of lepidopteran pupae or cocoons and even fewer have investigated species that are not forest pests. Here we present a study o...
