What if your home was more sacred than any church or temple? What if you could find spiritual comfort without abandoning your reason or values? What if you could understand why looking into a flame brings you ancient feelings of well-being? What if you could find greater meaning and happiness in your life and strengthen the bonds in your marriage and family? The true "spirituality of the home," the faith and flame of Vesta burned in antiquity for centuries, providing a spiritual focus for the home and strengthening marital and family devotion. Today, this tradition has been reignited in the modern world and is being embraced by a new generation of "spiritual but not religious" women, men and families. In The New Vesta Home, the essential companion to The New Vesta Secret, marriage author-expert and leading Vestal proponent Debra May Macleod teaches readers how this life-changing tradition can illuminate their lives, relationships and homes. From simple mealtime rituals to skills-based marriage and family-strengthening advice, The New Vesta Home is part spiritual treatise and part practical relationship manual. Use it to bring daily sparks of love, devotion, happiness and meaning to your life and home.Read with: THE NEW VESTA SECRET: FINDING THE FLAME OF FAITH, HOME & HAPPINESS

Acetylene systems present a new route to cyclic compounds as an alternative to more traditional methods employed in classical organic chemistry. The synthesis of cyclic structures based on acetylene systems has important applications in the formation of nanostructures, naturally occurring compounds and chemosensory materials for the design of nonlinear optics, electronic and photonic devices.
Alkynes in Cycloadditions presents a modern review of regioselective synthesis of aromatic and non-aromatic carbocyclic and heterocyclic ring systems based primarily on [2+2+2] and [4+2] cycloadditions, and other reactions of acetylenic units including enediynes and enyne-allenes.
Topics covered include:
- New strategies for the formation of aromatic and polynuclear hydrocarbons based on (Z)-hex-3-en-1,5-diyne and (Z)-hepta-1,2,4-triene-6-yne blocks.
- One-step synthesis of benzene derivatives, β-substituted naphthalenes and acenes by the cycloaromatization of enediynes and enyne-allenes by Bergman, Myers-Saito and Shmittel.
- Mechanisms of cycloaromatization resulting in the formation of fulvene and indene systems.
- Heterocyclization involving enyne-carbodiimides.
- New achievements in classical cycloaddition reactions such as the Diels-Alder condensation with acetylenic dienophiles and [2+2] cycloadditions with acetylene components
Alkynes in Cycloadditions presents a comprehensive summary of the literature to 2012 on methods for the synthesis of ring systems from acetylenes for academic researchers working in the fields of organic synthesis, physical organic chemistry, organometallic chemistry, catalysis, materials science, nanomaterials and biochemistry.
