dom’ reached anthesis most rapidly, while plants of ‘Mathilde Gütges’ and ‘Merritt’s Supreme’ were the slowest to f-lower. Table 2 represents days to anthesis and not days to salable color. In general, plants were salable, based on sepal color, ≈10 days before anthesis, so subtracting 10 days from data in Table 2 gives forcing times (from start to sale) for these cultivars when a 62F (17C) mini...

This paper describes the implementation of an attack on the Bluetooth security mechanism. Specifically, we describe a passive attack, in which an attacker can find the PIN used during the pairing process. We then describe the cracking speed we can achieve through three optimizations methods. Our fastest optimization employs an algebraic representation of a central cryptographic primitive (SAFER...

In our true scholarly spirit, the MJM remains committed to supporting budding scientist at all stages of their careers. This year we are pleased to provide you with a unique collection of abstracts outlining the high caliber projects that were undertaken by the most recent winners of the 27th annual Montreal Regional Science and Technology Fair (MRSTF) that was held at Marianopolis College from...

Average earth temperatures rose 0.6 oC over the last century, according to the latest Intergovernmental Panel on Climate Change. But that increase pales in comparison to the 1.4–5.8 oC expected increase over this century. As temperatures climb, climate models predict that high-latitude, high-altitude regions like Yellowstone National Park will experience shorter winters and earlier snow melts. ...

Cryptographic Hash functions find ubiquitous use in various applications like digital signatures, message authentication codes and other forms of security. Their associated vulnerabilities therefore make them a prevalent target for cyber criminals. General means of defeating hash based authentication involves both discovering and exploiting inherent weakness in cryptographic hash functions or b...

A study of the mechanisms of cracking-induced mistuning in bladed disks is presented in this paper. An analytical model for a bladed disk was formulated using lumped-mass-beams, and a cracked blade was represented by a beam with a through-crack at the root. Local stiffness reduction due to cracking was incorporated using a flexibility matrix method. The dynamic characteristics of the bladed dis...

To stain C. elegans with antibodies, the relatively impermeable cuticle must be bypassed by chemical or mechanical methods. "Freeze-cracking" is one method used to physically pull the cuticle from nematodes by compressing nematodes between two adherent slides, freezing them, and pulling the slides apart. Freeze-cracking provides a simple and rapid way to gain access to the tissues without chemi...

Fine-grained soils, in particular, expansive soils are prone to cracking. For these soils swelling-shrinking potential is quite high and hence they exhibit adverse affect on overall stability of geotechnical structures. This phenomenon may also be responsible for alteration of various engineering properties of soils such as hydraulic conductivity, water and leachate penetration, solute transpor...

CRACKING THE SCLEROTIC BONE RIM COMPARED TO REAMING +*Elmengaard, B; **Bechtold, JE; *Baas, J; Jakobsen, T; *Søballe, K +*Department of Orthopaedic Surgery, University of Aarhus, Denmark [email protected] INTRODUCTION Revision hip replacement implants have poorer clinical outcome than primary implants. The fixation of the implants is often compromised by the formation of an endosteal scleroti...
