نعناع فلفلی (L. Mentha piperita) گیاهی معطر دارویی است که کشت آن به‌دلیل فقر مواد آلی خاک در خوزستان محدود گشته است. از این‏رو انتخاب نوع و میزان کود جهت تضمین عملکرد مطلوب ضروری است. بدین‏منظور در مزرعه تحقیقاتی دانشگاه ‏رامین ‏خوزستان در سال 93-1392، آزمایشی فاکتوریل بر پایه بلوک‏های‏ کامل ‏تصادفی اجرا شد. عامل اول شامل سه فرم کود نیتروژنی مایع (اوره آمونیوم نیترات (...

Abstract Numerous studies have been reported to ascertain the benefits of starter fertilization for corn ( Zea mays L.) production, but most rely on data collected by measuring early growth or grain yield at harvest. As a more conclusive evaluation, five field trials were conducted using 15 N‐labeled urea‐ammonium nitrate (UAN) solution (90 kg N ha −1 ) compare single and dual subsurface band p...

A detailed study of the high temperature dynamics of the scalar sector of Little Higgs scenarios, proposed to stabilize the electroweak scale, shows that the electroweak gauge symmetry remains broken even at temperatures much larger than the electroweak scale. Although we give explicit results for a particular modification of the Littlest Higgs model, we expect that the main features are generi...

Urban Automation Networks (UANs) are being deployed worldwide in order to enable Smart City applications. Given the crucial role of UANs, as well as their diversity, it is critically important to assess their properties and trade-offs. This article introduces the requirements and challenges for UANs, characterizes the main current and emerging UAN paradigms, provides guidelines for their design...

Cereal rye (Secale cereale L.; CR) is promoted as a cover crop practice for reducing nitrate leaching losses in the U.S. Midwest. However, early-season nitrogen immobilization during CR decomposition may contribute to yield reductions corn (Zea mays L.). Field trials were conducted at three sites determine if N starter fertilizer could increase plant uptake and grain of following CR. Treatments...

This paper provides a description of a novel network layer protocol for underwater acoustic networking (UAN) that provides a mechanism for network control and management enabling the implementation of responsive, self-configuring, adaptable, and scalable networks whose performance are predictable. The protocol draws from the demonstrated efficiencies of multi-protocol labeled switching, dynamic...

A notation is presented for formally describing the design of a user-interface. The speciication of a system is given using the Object-Z formal speciication language and then extended to describe presentation using an Object-Z class library. The Object-Z notation is extended to enable designs to be described using UAN (User Action Notation) annotations and the semantics for the design extension...
