Cracks

An “eerie, elliptical masterpiece set in a South African boarding school in the early 1960s. . . . First-rate psychological suspense . . . played out flawlessly” (Kirkus Reviews). The members of an elite girls swim team are the reigning queens at their South African boarding school. And then Italian student Fiamma Coronna joins their ranks. Beautiful, athletic, and suddenly commanding all the coach’s attention, Fiamma is the envy of every girl on the team—until the summer she walks into the rural grasslands surrounding the school and disappears. Forty years later, the former teammates return to the school for a reunion, and the memory of that summer emerges like a long buried secret, the shocking, violent truth of what really happened to Fiamma no longer able to be contained . . . “Riveting . . . while evocative of The Prime of Miss Jean Brodie and Picnic at Hanging Rock, Kohler’s writing is so smoothly confident and erotic that she has produced a tale resonant with a chilling power all its own.” —Elle “A stunning and singular tale of the passion and tribalism of adolescence, Cracks lays bare the violence that lurks in the heart of even the most innocent. Shocking, reminiscent of Lord of the Flies . . . conjures up the wildness of the veld and the passion and drama of adolescence . . . peculiarly satisfying.” —The Times Literary Supplement “A disturbing, note-perfect novel. Dissection of evil has rarely been so extravagantly executed.” —San Francisco Chronicle “Polished, compact and chilling . . . Powerful.” —Publishers Weekly A Library Journal and Newsday Best Book of the Year, now a major motion picture starring Eva Green

Composites offer great promise as light weight and strong materials for high performance structures. One of the major advantages of these materials as compared with metals is the basic way in which heterogeneity resist crack extension. In a fiber/matrix composite system, the fibers tend to cause cracks to form at closer spacing and delay the formation of a large crack. The enhancement of local failure such as fiber breaking, matrix cracking and interface debonding further reduces the energy level which might have otherwise reached the point of catastrophic failure. Even though substantial tests have been made on composite materials, little has been gained in the understanding and development of a predic tive procedure for composite failure. There are fundamental difficulties associated with incorporating the nonhomogeneous and anisotropic prop erties of the composite into the continuum mechanics analysis. Additional uncertainties arise from voids and defects that are introduced in the composite during manufacturing. Even a small quantity of mechanical imperfections can cause a marked influence on the composite strength. Moreover, the interface properties between the fibers and matrix or bonded laminae can also affect the load transmission characteristics significantly. It would be impossible to establish predictive procedures for composite failure unless realistic guidelines could be developed to control the manufacturing quality of composite systems.

Stella greets Christopher when he shrinks and falls through the cracks in the school floor due to boredom. The two decide to look around and discover some classrooms where children are actively participating in their education and enjoying learning.

America’s founders feared a president like Donald Trump. Through the Constitution and the Bill of Rights, they erected a fortified but constrained government to secure the benchmarks of our democracy and established the guardrails designed to protect it. But Trump pushed almost every one of the Framers’ safeguards to its limit—most held, but some broke under the weight of presidential abuses even the Framers did not foresee. Thirteen Cracks will be the first book to expose the most vulnerable areas in our democracy, explain in historical context how President Trump uniquely and outrageously exploited these weak spots, and propose a fix for each challenge. Historian Allen J. Lichtman argues that Trump has put us at a pivot point in our history, where the survival of American democracy is at stake. But this is also an historic opportunity to shore up the vulnerabilities and to strengthen our democracy.

Restraint and intrinsic stresses in concrete at early ages are vitally important for concrete structures which must remain free of water-permeable cracks, such as water-retaining structures, tunnel linings, locks and dams. The development of hydration heat, stiffness and strength, also the degree of restraint and, especially for high-strength concrete, non-thermal effects, are decisive for sensitivity to cracking. Determining thses stresses in the laboratory and in construction components has led to a clearer understanding of how they develop and how to optimize mix design, temperature and curing conditions. New testing equipment has enabled the effects of all the important parameters to be qualified and more reliable models for predictiong restraint stresses to be developed. Thermal Cracking in Conrete at Early Ages contains 56 contributions by leading international specialists presented at the RILEM Symposium held in October 1994 at the Technical University of Munich. It will be valuable for construction and site engineers, concrete technologists and scientists.

When Bull Mastrick and Victor Konig wind up in the same psychiatric ward at age 16, each recalls and relates in group therapy the bullying relationship they have had since kindergarten as well as facts about themselves and their families that reveal how much they have in common. A first novel.

Fifteen-year old Victoria is fuming when her dad fails once again to be at the train station like he’s promised. When she sees a teen mother stash her bruised little boy in the train’s bathroom and get off the train alone, Victoria makes a split-second decision. She boards the next train out of town—taking the toddler with her.
