Design and Performance Analysis of a Log Periodic Dipole Antenna with a Frequency Range of 1350 to 2690 MHz
Abstract: The introduction of broadband systems to communication and non-communication technologies has demanded the design of broadband antennas. RF antennas have relatively small bandwidth and poor directivity while the log periodic dipole antenna (LPDA) provides better directivity and gain with wide bandwidth. For a communication link and data transmission at higher rates, wider bandwidth is required with high gain and directivity. This necessitates designing a wideband antenna. In this paper, a …

Reproductive Challenges in Tropical Dairy Cows: Exploring Stressors and Mitigation Strategies for Sustainable Development
Abstract: Reproductive efficiency in tropical dairy cows is often compromised by a range of environmental, nutritional, and management-related stressors. These stressors, including heat, humidity, poor-quality feed, disease, and parasitic infestations, significantly affect fertility, leading to prolonged calving intervals, reduced conception rates, and increased reproductive disorders. Heat stress, in particular, has been identified as a primary factor influencing reproductive performance by disrupting hormonal balance, reducing feed intake, and impairing overall cow health. …
