In der Rabi-Saison 2016-17 wurde auf der Agrometeorology Research Farm, Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) ein Feldexperiment durchgef hrt, um den "Einfluss von Feuchtigkeitsregimen auf Wachstum und Ertrag von Weizensorten (Triticum aestivum L.)" zu untersuchen. Der Versuch bestand aus 9 Behandlungskombinationen und wurde im Rendomized Block Design mit drei Wiederholungen getestet. Das Experiment bestand aus drei Feuchtigkeitsregimen, n mlich 0,8 IW/CPE-Verh ltnis, 1,0 IW/CPE-Verh ltnis und 1,2 IW/CPE-Verh ltnis und drei Weizensorten, n mlich. HUW-234, PBW-343 und NW-1012. Das Feuchtigkeitsregime mit einem IW/CPE-Verh ltnis von 0,8 erwies sich als geeignet f r ein h heres Wachstum und einen h heren Ertrag der Weizenernte. Die Weizensorte PBW-343 erwies sich als geeignet f r optimales Wachstum und Ertrag von Weizen. Der h chste Verbrauch (67,7 cm) wurde bei einem Feuchtigkeitsregime von 1,2 IW/CPE-Verh ltnissen gefunden und die h chste Wassernutzungseffizienz (81 kg ha-1 cm-1) wurde unter 0,8 IW/CPE-Verh ltnis berechnet. Unter den Weizensorten wurde die h chste Wassernutzungseffizienz von 74 kg ha-1 cm-1 f r die Weizensorte PBW-343 berechnet.

This book introduces 5 key feeding techniques such as coaxial probe, microstrip, conformal strip, aperture, and coplanar waveguide and covers different shapes of dielectric resonator antennas leading to improvement in circularly polarized (CP) performance. It introduces advancements in the field of dielectric resonator antennas and dilectric resonator antennas (DRAs). Five different types of feeding techniques (i.e. coaxial probe, microstrip, conformal strip, aperture, and coplanar waveguide) are described for obtaining CP followed by two modified shaped DRA (sector DRAs). Throughout this book, rectangular and circular with their modified shapes of the dielectric resonator are utilized, providing differing degrees of freedom as well as different variable parameters, including length, width, height, radius, aspect ratio and dielectric constant, which are tuned to obtain the desired antenna parameters.

Oceanic Strategy

Oceanic Strategy

sidottu
This book introduces the concept of “oceanic strategy,” expanding beyond traditional maritime and naval perspectives to include political, economic, socio-cultural, and ecological dimensions. It highlights the Indian Ocean Region as a critical arena for global power competition, where the abundance of resources, strategic significance, and emerging interests have made it a new frontier for opportunity, growth, and conflict. By incorporating aspects like oceanic security, resource exploration, the blue economy, and hydrography, the book presents a broader view of strategic thought and the role of oceanic spaces in national and global geopolitics.Focusing on key players such as India, China, the US, and other traditional and emerging powers, the book analyses the reorientation of national interests and the intensifying struggle for dominance in the Indian Ocean. It argues that control over this region is crucial for attaining influence in 21st-century geopolitics. The work also addresses non-traditional security threats like piracy and transnational crime, situating the Indian Ocean at the heart of modern geopolitical discourse.This book is an essential resource for students and scholars of international relations, strategic studies, and political science, offering critical insights into the evolving power dynamics shaping the future of the Indian Ocean Region.
