Deprotonation is the removal of a proton, from a Brønsted–Lowry acid in an acid-base reaction. The species formed is the conjugate base of that acid; the complementary process, when a proton is added to a Brønsted–Lowry base, is protonation. The species formed is the conjugate acid of that base. A species that can either accept or donate a proton is referred to as amphiprotic. An example is the H2O molecule, which can gain a proton to form the hydronium ion, H3O+, or lose a proton, leaving the hydroxide ion, OH−; the relative ability of a molecule to give up a proton is measured by its pKa value. A low pKa value indicates that the compound is acidic and will give up its proton to a base; the pKa of a compound is determined by many aspects, but the most significant is the stability of the conjugate base. This is determined by the ability of the conjugated base to stabilize negative charge. One of the most important ways of assessing a conjugate base's ability to distribute negative charge is using resonance.

Electron withdrawing groups or electron donating groups present on a molecule determine its pKa. The solvent used can assist in the stabilization of the negative charge on a conjugated base. Bases used to deprotonate depend on the pKa of the compound; when the compound is not acidic, and, as such, the molecule does not give up its proton a base stronger than the known hydroxides is required. Hydrides are one of the many types of powerful deprotonating agents. Common hydrides used are sodium potassium hydride; the hydride forms hydrogen gas with the liberated proton from the other molecule. The hydrogen is dangerous and could ignite with the oxygen in the air, so the chemical procedure should be done in an inert atmosphere. Deprotonation can be an important step in a chemical reaction. Acid–base reactions occur faster than any other step which may determine the product of a reaction; the conjugate base is more electron-rich than the molecule which can alter the reactivity of the molecule. For example, deprotonation of an alcohol forms the negatively charged alkoxide, a much stronger nucleophile

Caul (headgear)

A caul is an historical headress worn by women that covers tied-up hair. A fancy caul could be made of satin, fine silk or brocade, although a simple caul would be made of white linen or cotton; the caul could be covered by a hairnet to secure it from falling off. During the second half of the thirteenth century, network caps, more properly called "cauls", came into fashion for ladies' wear; these headdresses were shaped like bags, made of silver or silk network. At first they fit close to the head, the edge, band or rim being placed high up on the forehead, to show some hair on the temples and around the nape. Jewels were set at intervals in the band at the intersections of the cross-bars. Hilda Amphlett. Hats: A History of Fashion in Headwear. Dover Publications. ISBN 0-486-42746-3. Georgine de Courtais.

Dekh Indian Circus

Dekh Indian Circus is an Indian film directed by Mangesh Hadawale. It provides an entertaining metaphor for rural India's struggle to access the supposed economic miracle of that east Asian nation; the film premiered at the 16th Busan Film Festival in the New Currents section, opening to positive review from critics and winning the Audience Choice award. Nawazuddin Siddiqui and Tannishtha Chatterjee won the best actor and actress awards for this movie at the 12th annual New York Indian Film Festival. Kajro and Jethu are fulfilling the eternal Indian dream of educating their children Ghumroo and Panni. Kajro, the resilient mother, in the face of adversity inculcates great values in her children. Jethu as the mute patriarch suffers the day-to-day heartbreaks in silence. Set in the present-day deserts of barren Rajasthan, the story line is about the daily trials and tribulations of the family and depicts the aspirations of rural India. Aspirations have arrived at every doorstep. In the backdrop of state elections, a circus has come to a nearby town that may be Panni and Ghumroo’s only escapade to a fantasy world without any heartbreak.

A flag on the door could be the key to this escape. Would Jethu and Kajro find it easy to see a small dream of their children come true or would they themselves become puppets in the circus of life? Tannishtha Chatterjee as Kajaro, who lives in the rural part of the country, can be compared to the modern, empowered woman of today, her thoughts and values are rooted in Indian tradition and culture. From a young age she has been independent and strong willed. Nawazuddin Siddiqui as Jethu, belongs to the ‘Rabari’ community of Rajasthan, he resembles the ‘son of the soil’. His community comes under the broad classification of the nomadic tribe that moves from place to place. Jethu is a loving and caring husband and a father, he and Kajaro were childhood sweethearts, he has tremendous faith and trust in her. Virendra Singh Rathod as Ghumroo: the seven-year-old child of Jethu and Kajaro, he is in his school uniform or the Rabari costume. He sports some Rabari accessories, he has big bright eyes. They reflect purity.

They are deep and intense and are a mirror of his soul, pure and genuine. Suhani Oza as Panni, the five-year-old daughter of Kajaro and Jethu, she resembles her mother in many ways the sharp features. Panni is an innocent-looking girl, she exudes sweetness from the way she childlike mannerisms. The soundtrack of the film is composed by Shankar-Ehsaan-Loy, while the lyrics are penned by Prasoon Joshi; the score is done by Wayne Sharp. The film received overwhelmingly positive reviews from the critics. Richard Kuipers of Variety praised it for "bringing the themes of inequality and class divisions together in the entertaining visit to the big top." Kirk Honeycutt in his review for The Hollywood Reporter, praised director Mangesh Hadawale for portraying third-world issues through a family comedy that contains a stinging satire of contemporary India and its rampant corruption. 12th New York Indian Film FestivalWon- Best Actor - Nawazuddin Siddiqui Won- Best Actress - Tannishtha Chatterjee16th Busan International Film FestivalWon- Audience Choice Award60th National Film AwardsWon- National Film Award for Best Children's Film Won- National Film Award for Best Child Artist - Virendrasingh Rathore Won- National Film Award – Special Jury Award / Special Mention - Nawazuddin Siddiqui Won- National Film Award – Special Jury Award / Special Mention - Tannishtha Chatterjee

Regeneration (Roy Orbison album)

Regeneration is the twentieth album by Roy Orbison. According to the official Roy Orbison discography by Marcel Riesco, the album was released in November 1976, it marked the return to Monument Records where he had launched his greatest successes over fifteen years earlier where he released some of his greatest hits. However, it would be a one-time only rekindling of the business relationship as Orbison, not happy with the material he was given to record, asked Fred Foster to annul his contract - which he did.
