in this study, responses of four canola genotypes to salt stress in germination test and callus culture stages were investigated. the response of genotypes under salinity levels was significantly different. higher salinity resulted in less germination and growth of seedling. after callus culturing on liquid saline media, callus fresh weight and callus induction efficiency were significantly dif...

Dust accumulation capacity of Ficus carica L. and Psidium guajava L. was investigated from eight different sites of Multan, Pakistan.  Leaves of both plants were used for analyzing biometric (leaf area, fresh and dry weights) and biochemical attributes (chlorophyll contents, carotenoids and ascorbic acid).  Maximum dust accumulation was occurred in the plants growing near road...

Errors caused by radiation are a major problem for memories that have to operate in harsh environments. To evaluate the effects of radiation, memories are normally tested by exposing them to known rad...

Knowledge-collection and accumulation are essential functions for realizing a knowledge-creation environment. Our system for an objective-video with a story on the Internet focuses on expert-knowledge collection and accumulation based video contents with multimedia, such as images, texts and audio data. The purpose of this system design is to generate “relationships of uploaded data” across het...

We report on a healthy 39-year-old man who developed spontaneous pneumomediastinum during a soccer game without a traumatic impact. Chest radiography and CT demonstrated the extensive pneumomediastinum and subcutaneous emphysema. Treatment of this rare condition is conservative and prognosis is excellent.

We show that if K is a compact metrizable space, then the Banach space CpKq has the so-called Blum-Hanson property exactly when K has finitely many accumulation points. We also show that the space `8pNq CpβNq does not have the Blum-Hanson property.

Directed acyclic graphs provide a convenient representation of reticulate evolution in systematic biology. In this paper we formalize and analyse a simple model in which evolved characteristics are passed on to all descendant species. We show that the resulting observed sets of characteristics for the species at the leaves uniquely determine the digraph that described the evolution of the speci...

Network anomaly detection has been a hot research topic for many years. Most detection systems proposed so far employ a supervised strategy to accomplish the task, using either signature-based detection methods or supervised-learning techniques. However, both approaches present major limitations: the former fails to detect unknown anomalies, the latter requires training and labeled traffic, whi...

This paper presents an architecture to evaluate the reliability of a systemon-chip (SoC) during its runtime that also accounts for the system’s redundancy. We propose to integrate an autonomic layer into the SoC to detect the chip’s current condition and instruct appropriate countermeasures. In the autonomic layer, error counters are used to count the number of errors within a fixed time interv...

The "middle-class neighborhood" is a breeding design intended to allow new mutations to accumulate by lessening the effects of purifying selection through the elimination of among-line fitness variation. We show that this design effectively applies soft selection to the experimental population, potentially causing biased estimates of mutational effects if social effects contribute to fitness.
