Research on Old French: The State of the Art

The current quantity offers scholarly research into outdated French because it is practiced this day, in all of its varieties, inside of quite a few theoretical frameworks, from Optimality idea to Minimalism to Discourse research. some of the chapters are corpus-based, reflecting a brand new pattern within the box, as extra digital corpora develop into to be had.

Advances in Research on Cholera and Related Diarrheas

The United States-Japan Cooperative clinical technology application was once initiated in 1965 via joint contract among the President of the us and the major Minister of Japan. the aim of this system used to be to advertise cooperative biomedical learn among the 2 international locations, specially on illnesses of famous impor­ tance in Asia.

Residual Stress and Stress Relaxation

The military fabrics and Mechanics examine middle in coop­ eration with the fabrics technology team of the dep. of Chemical Engineering and fabrics technological know-how of Syracuse college has been accomplishing the yearly Sagamore military fabrics learn convention due to the fact 1954. the categorical objective of those meetings has been to collect scientists and engineers from educational associations, and govt who're uniquely certified to discover intensive a subject matter of significance to the dep. of safeguard, the military and the medical neighborhood.

Current status of sugarcane research in India

Sugarcane is among the most vital vegetation commercially grown in approximately one hundred fifteen international locations of the area. India is a massive manufacturer in addition to client of sugar on the planet and has produced approximately 25MT of sugar from 360MT sugarcane in 2011-13, contributing approximately 15 percentage of the whole sugar construction on this planet.

This should facilitate the addintion of the second molecule of aldehyde to the intermediate 10a with the formation of the compound Cl2POCHMeOCHMeCl 28a. 3 ppm were observed in the 31P NMR spectrum. The last two ones were ascribed to the phosphorus atom in the secondary intermediate 28a. PCl3 + 2 MeCHO o 20 C Cl2POCHOCHCl 28a - o 10 C Cl2 Me Me ClCHOCHCl + (POCl) n 16a 18a Me Me 16a + POCl3 According to integral intensities of the signals the ratio of products 1:10a:28a makes up 22:1:7. The main component of mixture is the initial PCl3.

A. Khairullin, R. F. Karimova et al. diethoxymethylphosphonate 56, respectively. By distillation in vacuo pure compounds 55 and 56 were obtained. Their constants are close to those described in literature [65]. It should be noted that interaction of individual catechol chlorophosphite with ethylene oxide, acetal, trialkyl orthoformate, with aldehydes activated by trialkyl phosphites, proceeds with considerable thermal effect. And the above described reactions of intermediates 12f-i with these nucleophils proceeded with weak exothermic effect.
