Engineer of the communication lines Mykola Pavlovych Petrov (1836–1920): factors for his scientific views’ formation

The article reviews the factors of the scientific views’ formation of Mykola Pavlovych Petrov – formidable Russian scientist and engineer in relation to his administrative efforts of development of the native scientific and technical community XIX–XX. The special focus was made on the biographical component, especially his study in Petersburg institutions. The crucial impact on the scientific destiny of M. P. Petrov was made by his studying in the Engineer Academy. In that time the intellectual basement for the future activities was formed. As a matter of fact, later M.P. Petrov became the formidable engineer and scientist. M. P. Petrov was the student of the formidable mathematician, academician of the Petersburg Academy of Science Mykhailo Vasylovych Ostrohradskyi (1801–1862). M. P. Petrov gained a lot of useful skills and knowledge from his teacher. Among those the following: high mathematical culture, abstract thinking, knowledge of the theoretical and practical problems in various areas of science, especially the ones that were related to railway transport. Work as the lecturer in the Technological Institute, communication with I. A. Vyshniehradskyi, A. P. Borodin and other scientists and specialists played a role of some kind of push for M. P. Petrov to study applied disciplines, mainly related to the friction of lubricated materials. Among the teachers of M. P. Petrov in the Academy was Herman Yehorovych Pauker (1822–1889). M. P. Petrov always recalled him as the wonderful engineer and teacher, who was the creator of the school for the engineers-teachers. The main goal of the school was the harmonious connection between engineer work and science. In the Academy M. P. Petrov met the lecturer of mechanics of the Institute of the communication paths engineer corps Stanislav Valerianovych Kerbedz. During the studying in the Academy M. P. Petrov was formed as the future scientist and specialist, who had the character which helped him to communicate easily with people. He had humane views and always acted alone and fairly. These features of his character in conjunction with his great mind helped him to achieve all his goals while solving the complicated engineer and administrative tasks. Aspiration to knowledge, original and brave thinking were among the main features of M. P. Petrov`s nature.

Rīgas Politehniskā institūta inženieru nodaļas absolventa Mihaila Krivošapkina (1888–1943) dzīves gājums un profesionālā darbība

Rīdzinieks, Rīgas Politehniskā institūta (RPI) Inženieru nodaļas absolvents (1914) Mihails Krivošapkins pēc studijām strādāja par inženieri Krievijā, kur būvēja elevatorus. No 1920. gada līdz izsūtīšanai uz Sibīriju 1941. gadā dzīvoja Rīgā un bija vairāku Latvijas tiltu projektu autors, strādāja par inženieri Rīgas būvvaldē, bija Rīgas domes deputāts (1925–1934). Darbojās dažādās sabiedriskās organizācijās. Inženiera darbu turpina viņa pēcnācēji – mazbērni un mazmazbērni. Rigan, the graduate of the Department of Engineering (1914) of Riga Polytechnic Institute (RPI) Mikhail Krivoshapkin, after studies worked as an engineer in Russia, where he built elevators. From 1920 until deportation to Siberia in 1941 he lived in Riga and was the author of several bridge projects in Latvia, worked as an engineer at Riga Construction Board, was a member of the Riga City Council (1925–1934). Worked in various public organizations. His engineer work is continued by his descendants – grandchildren and great-grandchildren.

Engineering a foundation for partnership to improve medication safety during care transitions

There are major gaps and barriers for patients and caregivers after hospital discharge to achieve safe medication use. Patients and caregivers are often not ready to take on the responsibility for medication management when transitioned from inpatient care. Current approaches tend to focus on adding isolated strategies. A system thinking can enable a fundamental transformation to redesign professionals’ interactions with patients and caregivers with an explicit goal to develop patients and caregivers into true partners, with targeted roles, skills, attitude, knowledge, and tool support. We must recognize the fact that medication safety during care transition and, more so, at patient homes is the property of a “work system”, in which the patient and caregivers are at the center, with collaboration with health professionals. Innovative ideas are needed to engineer work system components by systematically examining professionals’ interactions with patients and caregivers, such as those during hospital stays and transitions (e.g. follow-up phone calls, community pharmacist consults, and home visits). Based on human factors principles, we describe a set of recommendations on engineering partnership with patients and their caregivers at different stages of a care episode, to enable productive interactions among work systems that are distributed and are often limited in their ability to exchange information and co-align their interests.

Applying Projective Geometry in Design of Worm Manufacturing

The mathematical describing of the production process in mechanical engineer work in the euclidean space model and the base of the analytical describing of the projective space model is practically identical in the form, which makes it reasonable to discuss of the production geometry to approach of the projective geometrical negotiation in the . It is a fact that in one of the cases, using the approach of a projective geometrical connection and the mathematical-kinematical model resulted in expansion in the field of production precision, specifically considering the examination of the production of the conical worm by grinding wheel. The abstraction of the production geometry on projective space model has a few results in case of conical worms. The elliptical errors in production of the conical worm with arched or anything profile by grinding wheel can be eliminated by this method way to achieve the constant pitch, the torsion of profile and others.
