Provisioners capture items both for delivery and for self-feeding. In doing so, they may travel directly to and from a single location, visit several patches on each excursion from a delivery point, or alternate excursions to different destinations. Prey suitable for self-feeding versus delivery have differing attributes, which means that they are often best sought in different places. Visiting...

Nutrient loading into rivers is generally increased by human-induced land-use changes and can lead to increased surface water pollution. Understanding the extent to which land-use patterns influence nutrient loading is critical to the development of best-management practices aimed at water-quality improvement. In this study, we investigated total nitrogen (total N) concentration as a function o...

This paper presents a CPW-fed compact inverted L shaped microstrip antenna for wireless applications. The proposed antenna provides an omni directional radiation pattern and it utilizes the concept of coplanar wave guide (CPW). The main motive is to simplify the structure and to reduce the overall size of the antenna. This is done by loading the inverted L-strip over the conventional monopole p...

w w w . i j e c t . o r g Abstract GPS, Satellite phones, requires broadband, miniature size and circularly polarized antennas. Microstrip antennas have inherently narrow bandwidth, hence demanded enhanced bandwidth and size reduction. The present paper discusses the design of wideband compact and circular polarised MSA. The bandwidth of proposed antenna is enhanced by using EC stacked patch an...

By loading properly arranged slots in an equilateraltriangular microstrip patch, a dual-frequency and broadband operations of a single-feed triangular microstrip antenna are presented. Details of the proposed dualfrequency and broadband designs are described and simulated results of nearand far-field parameters are presented and discussed.
