Neutrosophic logics is one of the promising research instruments, which could be successfully applied by a theoretical physicist. Naturally, neutrosophic logics, being a part of modern logics, states that neutralities may be between any physical states, or states of space-time. In particular, this leads, sometimes, to paradoxist situations, when two opposite states are known in physics, while the neutral state between them seems absolutely impossible from a physical viewpoint.

We review in a pedagogical way the method of differential equations for the evaluation of D-dimensionally regulated Feynman integrals. After dealing with the general features of the technique, we discuss its application in the context of one- and two-loop corrections to the photon propagator in QED, by computing the Vacuum Polarization tensor exactly in D.

Mathematics for Physics: A Guided Tour for Graduate Students
Author: Michael Stone, Paul Goldbart | Size: 5.3 MB | Format:PDF | Quality:Unspecified | Publisher: Cambridge University Press | Year: 2009 | pages: 919 | ISBN: 0521854032
An engagingly-written account of mathematical tools and ideas, this book provides a graduate-level introduction to the mathematics used in research in physics. The first half of the book focuses on the traditional mathematical methods of physics - differential and integral equations, Fourier series and the calculus of variations. The second half contains an introduction to more advanced subjects, including differential geometry, topology and complex variables.

Standard Specification for Straight-Beam Ultrasonic Examination of Rolled Steel Plates for Special Applications
Abstract
This procedure covers the standard and acceptance standards for straight-beam, pulse-echo, ultrasonic examination of rolled carbon and alloy steel plates. The amplitude linearity of the apparatus to be used shall be checked by positioning the transducer over the depth resolution notch in the IIW or similar block. The inspection shall be performed in an area free of operations that interfere with proper performance of the test. The test shall be performed either by direct contact, immersion, or liquid column coupling. Grid scanning shall be conducted along a continuous perpendicular line on the center. All discontinuities causing complete loss of reflection shall be recorded.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This specification covers the procedure and acceptance standards for straight-beam, pulse-echo, ultrasonic examination of rolled carbon and alloy steel plates, 3/8 in. [10 mm] in thickness and over, for special applications. The method will detect internal discontinuities parallel to the rolled surfaces. Three levels of acceptance standards are provided. Supplementary requirements are provided for alternative procedures.
1.2 Individuals performing examinations in accordance with this specification shall be qualified and certified in accordance with the requirements of the latest edition of ASNT SNT-TC-1A or an equivalent accepted standard. An equivalent standard is one which covers the qualification and certification of ultrasonic nondestructive examination candidates and which is acceptable to the purchaser.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
