\"This volume is an unprecedented history of Louis Vuitton's women's bags, the most coveted line of accessories in women's fashion. At the heart of Louis Vuitton are its City Bags, a range of women's bags that dates back to the turn of the twentieth century. Featuring the trademark monograms of the house, the City Bag story began with the Steamer, a resort bag designed in 1901 to be packed inside a much larger steamer trunk. These bags have in a hundred years formally diversified into a dizzying array of handbags for every conceivable function demanded by the modern woman. Profoundly influential, City Bags are now known to millions by their descriptive names (Keepall, Bucket, Papillon, Alma, Locket, Noe, Speedy) and are still evolving into more fantastical forms. Lavishly illustrated with new and archival photography, historical graphics, landmark editorials, and ad campaigns, the volume traces the history of these specific bag families, and examines the earliest specimens and today's most sought-after collectibles, including Vuitton's collaborations with Takashi Murakami, Stephen Sprouse, Richard Prince, Yayoi Kusama, and Rei Kawakubo and one-off projects by Zaha Hadid, Shigeru Ban, Vivienne Westwood, Helmut Lang, Andrâee Putman, and of course, Marc Jacobs.\"--Amazon.com.

Fermi surfaces in superconductivity Recent quantum oscillation experiments on high transition temperature ( T c ) copper oxide superconductors have revealed the existence of a Fermi surface akin to that in normal metals, comprising fermionic carriers that undergo orbital quantization. The unexpectedly small size of the observed carrier pocket, however, leaves open a variety of possibilities for the existence or form of any underlying magnetic order, and its relation to d-wave superconductivity. Sebastian et al . report experiments on YBa 2 Cu 3 O 6.51 that reveal more than one carrier pocket. They find evidence for the existence of a much larger pocket of heavier mass carriers playing a thermodynamically dominant role in this hole-doped superconductor. Experiments on YBa 2 Cu 3 O 6.51 reveal more than one carrier pocket, and evidence is found for the existence of a much larger pocket of heavier mass carriers having a thermodynamically dominant role in this hole-doped superconductor. To understand the origin of superconductivity, it is crucial to ascertain the nature and origin of the primary carriers available to participate in pairing 1 , 2 , 3 , 4 , 5 , 6 . Recent quantum oscillation experiments on high-transition-temperature (high- T c ) copper oxide superconductors 7 , 8 , 9 , 10 have revealed the existence of a Fermi surface akin to that in normal metals, comprising fermionic carriers that undergo orbital quantization 11 . The unexpectedly small size of the observed carrier pocket, however, leaves open a variety of possibilities for the existence or form of any underlying magnetic order, and its relation to d -wave superconductivity 12 , 13 , 14 , 15 . Here we report experiments on quantum oscillations in the magnetization (the de Haas-van Alphen effect) in superconducting YBa 2 Cu 3 O 6.51 that reveal more than one carrier pocket. In particular, we find evidence for the existence of a much larger pocket of heavier mass carriers playing a thermodynamically dominant role in this hole-doped superconductor. Importantly, characteristics of the multiple pockets within this more complete Fermi surface impose constraints on the wavevector of any underlying order and the location of the carriers in momentum space. These constraints enable us to construct a possible density-wave model with spiral or related modulated magnetic order, consistent with experimental observations.

Pocket milling is the most known machining operation in the domains of aerospace, die, and mold manufacturing. In the present work, GA-OptMill, a genetic algorithm (GA)-based optimization system for the minimization of pocket milling time, is developed. A wide range of cutting conditions, spindle speed, feed rate, and axial and radial depth of cut, are processed and optimized while respecting the important constraints during high-speed milling. Operational constraints of the machine tool system, such as spindle speed and feed limits, available spindle power and torque, acceptable limits of bending stress and deflection of the cutting tool, and clamping load limits of the workpiece system, are respected. Chatter vibration limits due to the dynamic interaction between cutting tool and workpiece are also embedded in the developed GA-OptMill system. Enhanced capabilities of the system in terms of encoded GA design variables and operators, targeted cutting conditions, and constraints are demonstrated for different pocket sizes. The automatically identified optimal cutting conditions are also verified experimentally. The developed optimization system is very appealing for industrial implementation to automate the selection of optimal cutting conditions to achieve high productivity.

The improvement of the machining accuracy of boring and milling machines is imposed by the more and more demanding conditions on the accuracy of the work pieces to be machined. The specificity of this family, of boring and milling machines, consists of the horizontal motion of the milling spindle (quill) with implications on the application point of the gravity center. Thus, the variation of the application point of the sum of the component elements weights of the column saddle subassembly leads to modifications of the oil film thickness in the hydrostatic guideways, affecting the geometrical accuracy of the machine. This work is presenting a system of compensation and hydrostatic guiding of the column saddle subassembly. This new compensation system allows the pressure in the pockets to be modified by taking in consideration the position of the application point of the weight of the entire column saddle subassembly. The implementation of this compensation and guiding system on the boring and milling machine model AFP 220 has led to an increasing of two times the geometrical accuracy of the horizontality of the column saddle`s motion, compared to the variant without compensation.

The supply devices of the hydrostatic guideway pockets are elements with a major influence on the rigidity of the machine tool guideways. The value of the flow that circulates through these devices depends on the fluid viscosity as well. The researches in this field show that an important increase of the fluid temperature is produced when it passes through various orifices, slits and interstices that belong to the hydrostatic systems. The increase of the working temperature leads to decreasing the kinematic viscosity, with undesirable effects on the functioning of the hydrostatic guideways. In order to minimize this disadvantage, this work is presenting a constructive solution of a fixed supply device (flow control valve) with fluid temperature compensation. This type of device avoids the negative effects of increased fluid viscosity caused by the temperature increase as well, by automatically modifying the flowing cross section that is performed through a compensation bushing. The constructive solution of the new supply device is simple and involves relative low workmanship and costs. This supply device has been experimented on a rotary table model MRD 1500x2000, on the linear axis of 2200 mm travel. Through the comparative analyses of the new solution versus the standard one that was using as supply device a capillary type resistor, an increase of the guideway rigidity by 13% has resulted.

The main objective of this research is to develop a mechanical etching technique to produce micro mould dies having micro pockets of hundreds of μm. A powder blasting technique is applied to stainless steel plates based on predefined process conditions. This paper describes the performance of a powder blasting technique and the effect of the number of nozzle scanning times and the stand-off distance of the nozzle on the depth and width of pockets. Required blasting and measurement steps are performed to extract the relationships between given process parameters and machined results. Experimental results show that increasing the number of nozzle scanning times and decreasing the stand-off distance of the nozzle increase the depth and width of machined pockets. Increase of the width of the pockets results from mask film wear. The results of this research can be a fundamental basis to produce more accurate and smaller micro pockets using the powder blasting process .

Phlebiopsis gigantea fungus used in biological control of root rot is currently cultivated commercially in disposable, sterilizable plastic bags. A novel packed bed bioreactor was designed for cultivating P. gigantea and compared to the plastic bag method and to a tray bioreactor. The spore viability of 5.4 x 10⁶ c.f.u./g obtained with the packed bed bioreactor was of the same order of magnitude as the viabilities obtained with the other cultivation methods. Furthermore, the packed bed bioreactor was less time and space consuming and easier to operate than the tray bioreactor.

Brae-Anne McArthur of Guelph was second with 3,466 points, followed by Tricia Palmer of Calgary (3,452) and Saskatchewan's Lindsay Tasche (3,427). Amber Mosewich of the Huskies was one of six qualifiers Thursday for Saturday's 600-metre women's final. Mosewich, the defending CIS gold-medal winner who has been hampered by injury, qualified fifth overall in a time of 1:33.43. Calgary's Holly Ratzlaff was the top qualifier (1:32.85), followed by Manitoba's Kja Isaacson (1:35.07), Calgary's Renee Kaylor (1:33.25) and Windsor's Madeleine Woods (1:35.18). That's because the Field House has a 200-metre oval track. More and more CIS athletes have qualified on oversized 300-metre tracks, which feature a longer straightaway and, usually, faster results.

It's apparently not too late for an invite, because the already crowded field for this year's race just grew by one last week with the addition of two-time Pro/Celebrity winner Sean Patrick Flannery, making it a 22-car race, with 20 of the drivers winners of past races. We wouldn't like our chances of winning this year. Any other year we'd be a threat. This year, we'd just be a hazard.

He also co-wrote \"One Moment in Time,\" sung by Whitney Houston during the 1988 Summer Olympics, and the theme song for the sitcom \"Growing Pains.\"

[Mandi Tasche] pointed out that obesity is a major problem in society, and Run, Jump, Throw is a response to obesity rates. While there's a lot of money going into researching obesity, there's not a lot of money going into actually solving the problem, Tasche said.
