DYOPTYKA’s innovative solution for the reduction of speckle noise in projection displays, using a phase randomizing deformable mirror, is shown to achieve good performance both within a single 1 μs pulse duration and through sequences of such pulses.

conclusions the administration of dextrose saline was associated with a shortened active phase and second stage of labor in vaginally delivered nulliparous women. results of 174 objects enrolled, 150 women delivered vaginally and completed the study. there was a significant difference in the duration of active phase between the groups (ns: 270.20 ± 13.37 minutes; d5ns: 206.67 ± 11.72 minutes) (...

When the megalopa stage of estuarine crab species becomes competent for settlement and metamorphosis, it responds to specific chemical and physical cues from the adult environment. Delayed metamorphosis in the absence of such cues is beneficial insofar as it increases the probability of finding a suitable habitat, and it may also enhance the genetic exchange between separate populations. Howeve...

The relationships between a predator population's mortality rate and its population size and stability are investigated for several simple predator-prey models with stage-structured prey populations. Several alternative models are considered; these differ in their assumptions about the nature of density dependence in the prey's population growth; the nature of stage-transitions; and the stage-s...

Background and objectives: Plant extracts and their constituents are known to exert biological effects, especially antioxidant activity. Fumaria vaillantii (Fumariaceae) has several therapeutic effects in traditional medicine. Antioxidants are able to protect the human body from oxidative damage connected to the reaction of free radicals. Synthetic antioxidants have to...
