ABSTRACT A 19-year-old female came to our department with the chief complaint of facial asymmetry. Clinical examination showed skeletal class III relationship with mandibular prognathism, large reverse overjet, lower right mild crowding, and left hemimandibular elongation. After a thorough discussion with the patient, she accepted the proposal of orthognathic surgery and mandibular setback by bilateral sagittal split osteotomy (BSSRO), and therefore, tooth extraction was performed for 18, 28, 38, and 48 before the surgery. An improved superelastic Ti-Ni alloy wire (ISW wire), developed by Tokyo Medical and Dental University, was then used to facilitate the correction of lower crowding. Involved mechanism included intermaxillary elastics for a better interdigitation and jaw relationships. Adequate overbite and overjet were achieved after treatment completion.

Hard and adherent wear-resistant thin surface coatings are synthesized on an aerospace alloy AA2219-T6 alloy using plasma-assisted physical vapor deposition. Submicron size TiN coatings with Ti interlayers are deposited and evaluated as a function of different deposition temperatures varying from 100 °C to 200 °C. Features of deposited surface layers are evaluated using different techniques; these include field emission scanning electron microscopy equipped with energy dispersive spectroscopy and X-ray diffraction. Mathematical models developed by Yu. A. Bykov and S. Hogmark are considered to estimate the coating thickness using the Composite Hardness measurements. The values predicted by Bykov’s model grossly underestimated the thickness values and thus a correction factor is proposed. The actual coating thickness is measured by sandwiching the thin coating between the substrate and electrolytically deposited nickel layer; the observations are made using field emission scanning electron microscope. The present study successfully used corrected Bykov’s Model along with micro-indentation proved to be an easy, quick and accurate method to estimate the coating thicknesses of thin hard coatings on the soft substrate over a wide range coating thicknesses.

Целью статьи является разработка феноменологической математической модели формирования и роста фаз в части влияния температурной зависимости параметров диффузии на характер роста слоев в двухкомпонентной многофазной системе. Темой исследования является анализ влияния температурной зависимости параметров диффузии на изменение характера роста слоев в двухкомпонентных многофазных системах. Предложено решение задачи использования температурного режима процесса диффузии при разработке технологических процессов сварки, пайки, нанесении покрытий и других, при которых в диффузионной зоне образуются интерметаллические слои, карбиды, нитриды, субоксиды, фосфиды и т. п. с заданными и контролируемыми эксплуатационными характеристиками получаемых новых материалов, их соединений, покрытий и пр. Результаты решения задачи позволяют по известным параметрам температурного режима процесса диффузии, полученным при исследовании двухкомпонентной многофазной системы, целенаправленно контролировать динамику роста, состав образующихся в процессе диффузии слоев, и их выходные параметры в данной системе для получения новых материалов с заданными свойствами.

Rad najprije utvrđuje da iz pojma prvobitnog znanja (liangzhi 良知) Wanga Yangminga王陽明 (1472. – 1529.) ne slijedi subjektivni idealizam te da je vezan za transcendentalnu subjektivnost u smislu fenomenologije. Zatim, raspravlja se o pitanju ima li Wang pojam prvobitne sposobnosti (liangneng 良能). Argumentira se da se može naći u dvije glavne Wangove teme – »znanje i radnja jedno su« (zhixing heyi 知行合一) te »razmatrati Nebo i Zemlju i mnoštvo stvari kao jedno (rizomatično) tijelo« (以天地萬物為一體) ili ih smatrati »izvorno jednim s mojim (rizomatičnim) tijelom« (本吾一體). Pokazuje se da su prvobitno znanje i sposobnost dva aspekta isto fenomena. Istinito je na razini virtualnog »rizomatskog tijela« (ti 體), a ne na razini stvari razmatranih kao potpuno oblikovane i aktualizirane (xing 形), kako se pojavljuju u empirijskom umu, zamagljeni žudnjama (yu 欲) koje postaju fiksirane na razini aktualnog. Te se žudnje mogu razriješiti putem »proširenja (prvobitnog) znanja« zhi (liang)zhi 致(良)知. Usporedni pojam »proširenja (prvobitne) sposobnosti« (zhi liangneng 致良能), koji Wang Yangming ne koristi, može se unijeti u sustav.
