An unceasing problem of our prevailing society is the fair division of goods. The problem of fair cake cutting is dividing a heterogeneous and divisible resource, the cake, among n players who value pieces according to their own measure function. The goal is to assign each player a not necessarily connected part of the cake that the player evaluates at least as much as her proportional share. I...

A temperature-dependent xylem occlusion was found in cut chrysanthemum stems (Dendranthema grandiflora, cv. Viking) which were placed for 24 h in air at 5°C prior to vase life evaluation. The response was inhibited by a 5-h treatment, prior to placement in air, with aqueous solutions at low initial pH or solutions containing near-neutral antioxidants (n-propylgallate, phloroglucinol, butylated ...

Fair allocation of goods or resources among various agents is a central task in multiagent systems and other fields. The specific setting where just one divisible resource is to be divided fairly is commonly referred to as cake cutting, and agents are called players in this setting. Cake-cutting protocols aim at dividing a cake and assigning the resulting portions to several players in a way th...

ABSTRACT The cultivation of vascular plants in aquaculture is becoming increasingly important and saline aquaponics have been centered on with a short life cycle (i.e. annual species). However, the perennial halophytes can allow to produce biomass year-round by repeated cuttings regrowth. present study evaluated effects different cutting regimes growth tissue nitrogen uptake halophyte Paspalum ...

introduction: the purpose of this study was to evaluate the morphologic surface of gutta­percha cones after cutting with different methods. materials and methods: the apical 3 millimeters of forty standardized, gutta-percha cones size 40 were cut off using scissors or a scalpel against a glass slab. the samples were then examined under scanning electron microscopy (sem) for topographic deformit...

Amyotrophic lateral sclerosis (ALS) still remains a deadly neurodegenerative disease, mainly characterized by the combined degeneration of both upper and lower motor neurons (MNs). The pathology perspective is changed after 2006 due to the demonstration of common inclusions in ALS and Frontotemporal Dementia (non-tauFTD). Genetics largely contributed to further define the common mechanisms of b...

the new non-conventional cutting process by the use of thermal shock is a convenient procedure for cutting the brittle materials such as glasses and ceramics. this method is based on the application of localized thermal shock to brittle materials by the use of hot air jet, which induces thermal stresses at the tip of an existed pre-crack. due to the thermo-elastic behavior of materials, the pre...

introduction cultivated alfalfa (medicago sativa l.) is the main, most of the time the only, forage for ruminants in iran as well as many other parts of the world. harvesting high quality forage is critical for iranian dairy industry, because it affects the performance of animals and reduces amount of concentrates utilization in dairy diets. unfortunately the most parts of the concentrates ingr...

in the present study, shearing properties of sugar cane stems were determined at five moisture content levels (46, 54, 62, 70 and 78% wb), three shearing speed (5, 10 and 15 mm min-1) and at ten positions on the stem. for measuring the shearing forces, the stems were severed by using a computer aided cutting apparatus. decrease in moisture content of stem from 78 to 46% wb led to 16.3 and 16.7%...
