This paper presents the design, construction, and testing of a high directivity circularly polarized small patch antenna for RFID Base Stations (Readers) operating in European UHF band. The designed optimized structure has 15cm ×15 cm × 0.6 compact size where -3dB beam angle is reduced by using slotted ring embedded patch. gain at 862 MHz 3.2 dBic with E H plain are 61.6º 65.2º respectively. Fi...

In this study, I used wood pellets as an eco-friendly sound-absorbing material. The aim of the research was to analyze effect filling height on sound absorption. This done using two types different lengths (A group: 1.5–3 cm, B less than 1.5 cm). With increasing pellets, optimum absorption shifted towards a lower frequency. group had better capacity A ones. coefficient filled 7 cm 0.722 at 864 ...

To study the association of multidrug-resistant enteroaggregative Escherichia coli with persistent diarrhea in Kenyan children, stool specimens were obtained from 862 outpatients under 5 years of age from July 1991 to June 1993. E. coli O44 was identified as the sole bacterial pathogen in four patients experiencing at least 14 days of fever, vomiting, and diarrhea. Disk diffusion testing showed...

We develop a general model of edge spaces in order to generalize, unify, and simplify previous work on cycle spaces of infinite graphs. We give simple topological criteria to show that the fundamental cycles of a (generalization of a) spanning tree generate the cycle space in a connected, compact, weakly Hausdorff edge space. Furthermore, in such a space, the orthogonal complement of the bond s...
