to evaluate integrated weed management on yield and weed biomass of bean an experiment were conducted as a split plot based on randomized complete block design with three replications at the research station of agriculture  in damavand in 2014.main plot of the mechanical control (cultivation)levels including the application and no application of cultivator and sub-plots chemical control levels ...

It is well known that there are five classes of sloops of cardinality 16 " SL(16)s" according to the number of sub-SL(8)s [4, 6]. In this article, we will show that there are exactly 8 classes of nonsimple sloops and 6 classes of simple sloops of cardinality 20 "SL(20)s". Based on the cardinality and the number of (normal) subsloops of SL(20), we will construct in section 3 all possible classes...

This case study concerns the speciication and validation of a Security Policy Model (SPM) for an electronic network. The network is intended to provide processing and transmission services for electronic messages, including sensitive and classiied material, over distributed sites and supporting multiple levels of security classiication. The SPM is formally speciied in VDM-SL and validated by sh...

Data from 15 modern studies are used to characterize the deviations from Webcr's law for intensity discrimination of 1000-Hz tone pulses. The results show that Weber's law is satisfied in the region 10-40 dB SL, that resolution descreases with decreasing intensity below 10 dB SL and increases with increasing intensity' above 40 dB SL, and that resolution at 90 dB SL is roughly 2.5 times better ...

PRETRIEVE is a belief-network-based, unsolicited information-retrieval system that performs machine learning based on user feedback. We report here on the document-ordering and document-retrieval performance of PRETRIEVE. We developed a test collection of 410 judgments of document utility in a simulated medical order-entry context. We characterized the validity of these judgments, which were el...

Let k 2 Z and let SL 2 (Z) denote the special linear group SL 2 (Z) = a b c d : a; b; c; d 2 Z and ad bc = 1 : A modular form of weight k is an analytic function f de…ned on the complex upper half plane H = fz 2 C : Im(z) > 0g that transforms under the action of SL 2 (Z) according to the relation [1] f az + b cz + d = (cz + d) k f (z) for all a b c d 2 SL 2 (Z)

In this study we examined the construct and external validity of the Disgust Scale Revised (Olatunji, Williams, et al., 2007), in a large heterogeneous sample (N = 1427). In addition, we investigated the role of demographic variables on disgust’s sensitivity. The findings reveal that the DS_R adheres to the three-factor structure (i.e., Core disgust, Animal-Reminder Disgust, and Contamination-B...
