Abstract:
... We report a new fabrication method referred to as ‘drill and fill’ lithography that provides control structuring and excellent reproducibility in the production of patterned platinum electrodes in a chip format, and demonstrate their sensing abilities for the label-free immunodetection of the HER-2 (human epidermal growth factor receptor-2) antigen. ...

ISSN:
0567-7572
Subject:
Europeans; gardening; gardens; groves; occupations; peaches; personal development; plums; trees; villages; China; Europe
Abstract:
... To Europeans “China” has served for many centuries as a label, as a blank and a promise. This is reflected in garden architecture as well as in literature. Garden architectural details considered exotic, grotesque, and imitative such as villages, pagodas, pavilions, bridges, etc. and poems, novels, fairy tales, plays, etc. carry many “Chinese” imaginations. They oscillate between sophistication an ...

Abstract:
... The knowledge of spatial variability is particularly important and several studies were carried out around the world, since it has been speculated that the overall grape quality is negatively affected by the vineyard heterogeneity. Based on this, a project was carried out in “LA VIARTE” (one important winery in the Friuli Colli Orientali D.O.C. area) with the aim to examine the spatial variability ...

Acta agrobotanica v.60 no.2 pp. 31-37
ISSN:
2300-357X
Subject:
carnivorous plants; nectar; nectaries; pollination; trapping
Abstract:
... In carnivorous plants, two types of nectaries occur: extra-floral nectaries, generally associated with prey luring, and floral ones associated with pollination. Nectar produced by extra-floral nectaries not only attracts prey but may also be involved in trapping prey and plays a role in myrmecophily. The diversity of nectary structure in carnivorous plants reflects complicated evolutionary routes ...

Abstract:
... We developed a simple polynomial taper equation for poplars growing on former farmland in Sweden and also evaluated the performance of some well-known taper equations. In Sweden there is an increasing interest in the use of poplar. Effective management of poplar plantations for high yield production would be facilitated by taper equations providing better predictions of stem volume than currently ...

Abstract:
... Recent events suggest that social media, also called web 2.0, can support mass social change. Although some critics have lamented how social media are eroding people’s ability to communicate, others have argued that social media may allow individuals to leverage their individual voices against authoritarian leaders. This article seeks to understand the ways in which individuals can use a particula ...
