We probabilistically model dynamic routing on un-buuered 2-dimensional tori. We consider shortest-path routing with packet loss and retransmissions versus a newly proposed all-link busy (ALB) hot-potato routing strategy with packet deeections. Computations of the sustained packet generating rate, node through-put, and average packet latency indicate that the proposed ALB strategy is a much bett...

Recent work on hot-potato routing [1] has uncovered that large transit ASs can be sensitive to hot-potato disruptions. Designing a robust network is felt as overly important by transit providers as paths crossed by the traffic have both to be optimal and reliable. However, equipment failures and maintenance make this robustness non-trivial to achieve. To help understanding the robustness of lar...

The current study includes isolation of laccase producing fungus from compost soil and characterization of the laccase enzyme. In our study, 11 fungal isolates were isolated by serial dilution. They were cultivated on potato dextrose agar (PDA) plate with indicator compound 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) to screen for the laccase production ability. Out of 11 iso...

In hot-potato (deflection) routing, nodes in the network have no buffers for packets in transit, which causes conflicting packets to be deflected away from their destinations. We study one-to-many batch routing problems on arbitrary tree topologies. We present two hot-potato routing algorithms, one deterministic and one randomized, whose routing times are asymptotically near-optimal (within pol...

Potato has become one of the primary cash crops in the arid region of the Loess Plateau. However, what and how cereal crops to rotate with potato is better for the farmer’s income and environment is unclear now. 11 potato based rotation systems were simulated in Yulin, using EPIC model based on local information. Results showed 1) Though mean potato yield decreased from 6.84 to 5.38 t/hm, the m...

Abstract To find out how maize and potato can grow and develop in an intercropping system rather than each grown alone in a sole cropping system the following factorial experiment was performend in the frame-work of a randomized complete block three replications in the experimental farm of the faculty of agriculture, Zanjan University in year 2004. Different potato to maize ratios of (1:0), i...

Fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. Fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (VCGs) and rep-PCR DNA fingerprinting. Nit ...

: fried products derived from potato, particularly potato crisp have been widely included in food basket of the households in the recent years in iran. potato crisp, among other products, is of great importance and is considered as competitive products. this product is in the list of the food products with high acrylamide content. therefore, due to the nutritional importance of this product and...
