• The Use of Ethyl Sulfone-bis-acetate in the Identification of Aliphatic Amines¹
  作者：John P. Alden、Bruce Houston

  DOI：10.1021/ja01317a040

  日期：1934.2

  Arnold Alberts in 1930 found this ester to condense easlly with ammonta to form a diamlde which melted at 226°C. With the hope of forming substitute diamides having melting points of wide variance. easily obtained and easily purified. work was begun upon condensation of the ester with various aliphatic Amines. Ethyl Sulfone-bis-Acetate is a clear viscous liquid with the formula ILC,OtC-CIL-SO.-CIL-COtCJL

  Arnold Alberts 在 1930 年发现这种酯很容易与 ammonta 缩合形成 diamlde，在 226°C 熔化。希望形成具有广泛差异熔点的替代二酰胺。容易获得且容易纯化。在酯与各种脂族胺缩合后开始工作。乙基砜-双乙酸酯是一种透明粘稠液体，分子式为 ILC,OtC-CIL-SO.-CIL-COtCJL。它对皮肤无刺激性。不挥发。并且不吸水。酯与各种胺的下列缩合得到这些熔点：N-戊基二胺，170°C；异戊基，152°C；正丁基。192°C；异丁基，130°C；正庚基，180°C；正丙基，174°C。至今仲碳原子上的胺基团和仲胺不缩合。但进一步的研究可能会找到浓缩它们的方法。

  A process for the preparation of photographic binary sensitizing dyes, which comprise two separate, nonconjugated chromophores, one of which has the capability of adsorbing to a silver halide grain surface, the other of which is substantially non-adsorbing to silver halide. The process comprises reacting two dye compounds in a solvent in the presence of a 2-halo-1-alkylpyridinium salt and a 4-dialkylaminopyridine.

• Modeling of Fried Potato Chips Color Classification using Image Analysis and Artificial Neural Network

  日期：2003.9

  ABSTRACT: Quality of potatoes in chips industry is estimated from the intensity of darkening during frying. This is measured by a human jury, subject to numerous factors of variation. Gray level intensities were obtained for the apex, the center, and the basal parts of each chip using image analysis of frying assays. We then tested a feed forward artificial neural network designed to associate these data with color categories. It behaved in good agreement with human estimations, obtaining correlation coefficients of 0.972 for training data and of 0.899 for validation data. A systematic study of the response of the model allowed understanding the criteria of evaluation used by the human operators.

• Synthesis of 2,6-dicarbethoxy-3,5-diaryltetrahydro-1,4-thiazine-1,1-dioxide derivatives as potent anticonvulsant agents
  作者：Naushad Edayadulla、Penugonda Ramesh

  DOI：10.1016/j.ejmech.2014.01.010

  日期：2015.12

  An efficient synthesis of 2,6-dicarbethoxy-3,5-diaryltetrahydro-1,4-thiazine-1,1-dioxide derivatives has been achieved under aqueous medium for the first time in good to excellent yields. All the synthesized compounds were tested for anticonvulsant activity using the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) screens, which are the most broadly employed seizure models for early identification of candidate anticonvulsants. Their neurotoxicity was determined applying the rotarod test. Seven compounds 4a, 4d, 4f, 4h, 4o, 4p and 4q showed promising anticonvulsant activities in both models employed for anticonvulsant evaluation. The most active compound 4d showed the MES-induced seizures with ED50 value of 10.2 mg/kg and TD50 value of 288.6 mg/kg after intraperitoneal injection to mice, which provided compound 4d with a protective index (TD50/ED50) of 28.3 in the MES test.
