Determining the Direction of Radio Wave Reception for Maximum Radiation Using Genetic Algorithm and RF to DC Conversion Efficiency Analysis

Engineering Reports, Volume 7, Issue 9, September 2025.
In this study, a new plan for routing radio transmitters is presented using an algorithm compatible with RFEH. The proposed algorithm is based on the genetic algorithm (GA), and in an innovation, using the HPBW in the GA creates a population for initial sampling dependent on the receiver antenna.

Access to reticulated water in late‐pregnancy: impacts on ewe productivity, drinking behaviour and some physiological indicators of dehydration

New Zealand Journal of Agricultural Research, Volume 68, Issue 4, Page 689-702, August 2025.
ABSTRACT There has been industry debate regarding sheep access to waterways, although there is little information available on the impact of access to water on sheep productivity. It is theoretically possible for actively growing pasture to provide sufficient moisture to meet the daily water intake requirements of sheep.

“Dream Big but Be Realistic”: Rural School Counselors and Students' College Choice

Psychology in the Schools, Volume 62, Issue 7, Page 2001-2011, July 2025.
ABSTRACT We interviewed Texas rural school counselors in schools with students who are first generation and low‐income. Two research questions were addressed: (a) How do rural high school counselors understand students' college and career choice process? (b) How do school counselors expand or limit the college choice of rural students?
