With the two most profound conceptual revolutions of XX century physics, quantum mechanics and relativity, which have culminated into relativistic spacetime geometry and quantum gauge field theory as the principles for gravity and the three other known fundamental interactions, the physicist of the XXI century has inherited an unfinished symphony: the unification of the quantum and the continuu...

Recent developments concerning canonical quantisation and gauge invariant quantum mechanical systems and quantum field theories are briefly discussed. On the one hand, it is shown how diffeomorphic covariant representations of the Heisenberg algebra over curved manifolds of non trivial topology involve topology classes of flat U(1) bundles. On the other hand, through some examples, the recently...

Based on the physical projector approach, a nonpertubative quantization of the massless Schwinger model is considered which does not require any gauge fixing. The spectrum of physical states, readily identified following a diagonalization of the operator algebra, is that of a massive pseudoscalar field, namely the electric field having acquired a mass proportional to the gauge coupling constant...

The density, temperature, and punch head velocity are dominant factors to the variation of compacted snow hardness measured by penetrometers. This effect is essential construction operation roads. Improved Motor-driven Snow Penetrometers (IMSP) utilized in this research control penetration speed measure true cone during penetration. study employs a multi-method approach combining orthogonal exp...

OBJECTIVES To determine the frequency of hypovitaminosis D in children presenting with Idiopathic musculoskeletal pain IMSP). METHODOLOGY The cross-sectional research was carried out at Peshawar’s Hayatabad Medical Complex’s Department Pediatrics. study duration 6 months. comprised 151 patients non-specific who were tested for vitamin levels to diagnose hypovitaminosis. RESULTS age range partic...

Comparison of data obtained personally during 1989-1996 with for 2018-2021. The children were undergoing inpatient treatment in the maxillofacial surgery department IMSP Children’s Clinical Hospital „E. Cotsaga”. observations on 119 odontogenic cysts jaws served as material this work. years and 85 hospitalized In diagnosis jaws, traditional research methods used: examination, palpation, radiogr...

The purpose for possible failure that occurs or has happened. After known, next alternative to prevent errors will occur and/or activities/actions discovery known process when spare part runs from stopper at shu...

Introduction. COVID-19 infection is common in the pediatric population, presenting a variety of respiratory manifestations and complications.
 Material methods. The study included 64 children from section, IMSP IMC, with mean age 2,04±0,4 years (variations 1 day-17 years), divided into 5 groups: 0-1 month, 1-12 months, 1-3 years, 3-7 >7 years. methodology expected to assess significance...

This report is a collection of the papers presented at the joint World Technology Evaluation (WTEC), National Science Foundation (NSF) and the Institute of Machine Science Problems (IMSP) workshop on Nanoparticles and Nanostructures in St. Petersburg on August 21, 1997. The workshop was devoted to nanostructure research in Russia and other states of the former Soviet Union (FSU). The papers inc...
