In the conventional methods of herbicide and fertilizer application, a substantial amount of toxic chemicals is sprayed or broadcast into the furrows, which is later washed away by irrigation water and may contaminate ground water, human and animal environment. If herbicide and fertilizer application could be limited to the most needed parts of the field rather than overall broadcasting, the me...

The Multiswitch project at Purdue University is investigating broadcast techniques for use in point-to-point networks. This paper analyzes four techniques for delivery of a broadcast message to all processors in a network. The current Multi-switch prototype network uses one of these techniques, called Flooding with Duplicate Discard (FDD). FDD is attractive because it provides high reliability ...
غلظت فلزات سنگین در نمونه های آب زیرزمینی و سطحی، خاک و رسوبات محدوده شهرک صنعتی شیراز برای بررسی آلودگی ناشی از استقرار صنایع، فعالیت های کشاورزی و شهرنشینی مورد مطالعه قرار گرفت. نمونه برداری از خاک در سه عمق متفاوت صورت گرفت. عناصر ni، as، mo، cu، pb و zn غنی شدگی بیشتری را در عمقهای a و c در مقایسه با عمق b نشان می دهند. بررسی ضریب آلودگی و ضریب آلودگی اصلاح شده بر اساس غلظت زمینه خاک، آلود...
Network wide broadcasting in Mobile Ad Hoc Networks (MANET) provides important control and route establishment functionality for a number of unicast and multicast protocols. We present an overview of the recent progress of broadcasting and multicasting in wireless ad hoc networks. We discuss two energy models that could be used for broadcast: one is non-adjustable power and one is adjustable po...
This paper addresses the problem of broadcasting and multicasting in large scale multihop ad hoc wireless networks. We focus on the energy-efficient broadcast routing in stationary networks and consider the case where wireless nodes can dynamically control their transmission power for each broadcast session. Minimum spanning tree (MST) has the property that the longest edge in the tree is the s...
This pot experiment was carried out to investigate the efficacy of certain Zn-amino chelates, i.e. Zn-glycine [Zn(Gly)2], Zn-arginine [Zn(Arg)2] and Zn-histidine [Zn(His)2] in supplying zinc for wheat was compared with a commercial Zn-sulfate fertilizer. Three wheat cultivars, differing in Zn-efficiency, including Back Cross Rowshan, Kavir and Durum were planted at Research Greenhouse of Isfaha...
In the present research in order to investigate the effect of foliar application of zinc (Zn) on some physiological and agronomic traits of safflower cultivars under drought tension, an experiment was conducted as a split plot factorial based on randomized complete blocks design with three replications for two years (2016-2018) at the experimental field of Seed and Plant Improvement Research In...
Herbicide resistant crops are commercially advantageous for efficient field productivity by enabling use of nonselective herbicides for weed management. Herbicide resistant trees could be used to improve productivity and reduce the costs of forest management through to the first and second years post tree establishment. We describe the introduction of the phosphinothricin acetyltransferase (bar...
Wireless multicast/broadcast sessions, unlike wired networks, inherently reaches several nodes with a single transmission. For omnidirectional wireless broadcast to a node, all nodes closer will also be reached. Heuristic algorithms for constructing the minimum power tree in wireless networks have been proposed by Wieselthier et al [1] and Stojmenovic et al [4]. In this paper, we present the e-...
