Calcite Needles in Syros Marbles
INTRODUCTION The rocks on the Greek island of Syros are part of a suite of high pressure metamorphic rocks which outcrop all across the Cyclades. There is a complex metamorphic history recorded in the rocks here, including a Cretaceous or Eocene high-pressure blueschist event and a Miocene, extension-related greenschist overprint. The Island of Syros is mostly composed of schists , which altern...
متن کاملRemotely Controllable Liquid Marbles
With the ongoing need for miniaturized systems in many biological and chemical applications, there is an increasing demand for the development of versatile methods for controllable transport and manipulation of small volumes of liquids. [ 1–9 ] Recently, liquid marbles — liquid droplets encapsulated by self-organized hydrophobic particles at the liquid/air interface — have been revealed as a ne...
متن کاملTaphonomic Bias in Analyses of Drilling Predation: Effects of Gastropod Drill Holes on Bivalve Shell Strength
T h e proportion of bivalve shells with drill holes i n fossil assemblages is commonly used as a measure of the intensity of predation by drilling gastropods. Previous studies have assumed that drilled and undrilled bivalve shells have equal preseruat ion wotentials. W e tested this assumption by measuring the mechanical strength of drilled and undrilled valves of the Recent bivalve Mulinia lat...
متن کاملPath Optimization For Computer Numerical Control-Printed Circuit Boards In Holes Drilling Process - Case Study
Electronic manufacturing sector uses Computer Numerical Control (CNC) machines for drilling holes on Printed Circuit Board (PCB). Some machines do not choose the optimal route when completing their tasks. Hence, this paper proposes an approach, which is based on my Algorithm Shortest Path Search Algorithm (SPSA), for finding the optimal route in PCB holes drilling process. In SPSA, when the rob...
متن کاملPlasmonic Enhancement During Femtosecond Laser Drilling of Sub-wavelength Holes in Metals
Precise ablation of metals using tightly focused femtosecond laser pulses with intensities close to the damage threshold can yield sub-wavelength, nanometer-sized holes or craters. These structures in metals can exhibit plasmonic effects, thereby affecting the interactions involved. We numerically simulate light propagation inside such holes and model the ablation process. We show that surface ...
