Abstract The approximate theory derived in this paper describes, by means of a “traveling-wave” approach, the behavior of beams under transverse impact. Lateral impact is considered in detail, namely, one in which a section of the beam undergoes a sudden change in velocity or shear force. The theory considers the effects of shear deformations and of rotatory inertia according to Timoshenko’s model, and that of lateral contraction as suggested by Love. The governing equations and the boundary conditions are developed with the aid of an energy-variation technique. Numerical examples are given in which the behavior of the boundary layer near the point of impact is examined. For one of these the exact solution is available and is in agreement with the present approximate results. Some general considerations concerning the velocity of propagation also are discussed.

The paper presents the method of a microscopic study of ceramic chips which can be useful in the analysis of physical phenomena regarding machining of ceramic materials. The analyzed chips were obtained on the milling machine tool from the Al2O3 based ceramic material. The measurements were performed using focus-variation technique (FVT). The InfiniteFocus Real3D microscope from Alicona Imaging company was applied. The paper mainly focuses on the methodology of measurements and the application of microscope’s software tools which can be used in the analysis of chips' 3D scans. The conditions of measurement process are discussed on the basis of the results of exemplary measurements of ceramic chips.

Union Territory

Agriculture and its allied activities are the main sources of livelihood in India. Jammu and Kashmir (J&K), a union territory of India is also an agrarian state. More than 70 percent of its population is directly engaged in this sector. Geographically, J&K lies in the Himalayan region and has a huge variation in agro-climate diversity. The climate here varies from sub-tropical in the Jammu division to temperate in the Kashmir division. These climatic variations make it suitable for performing varied cultivation. The productivity of all the major crops in the region has increased manifold since the green revolution but now it is more or less stagnating. Hence, it is useful to examine the productivity of major crops in the union territory. The present paper is an attempt to highlight the overall agricultural production of major food grains crop of J&K from 2000-2001 to 2018-2019. The main focus of the paper is to analyzes the variations in agricultural production and productivity of major crops at the district level in the Jammu division for the period 2010-2011 to 2016-2017. The study is based on secondary data and is empirical in nature. The co-efficient of Variation technique has been used to find out the variations in production and productivity of agricultural crops of the jammu division of J&K. The results show that the overall agricultural production of food grains crops in the region increases over years.It also shows tremendous variations in the production and productivity of the different crops across districts. These variations indicate that there is a need to adopt some specific strategies at the district level for the sustainable development of agricultural growth in the state.

Variation Technique

This paper describes a new method for determining porosities in two porous construction and geologic materials (asphalt and soil) by using ground-penetrating radar (GPR) over a wide range of controlled degrees of water saturation [Formula: see text]. We call this method a cyclic moisture variation technique (CMVT). Freshwater is used as an enhancer or a tracer to allow GPR to easily detect and differentiate amounts of water or other moisture in these materials. The CMVT is based on measuring the changes of real permittivity [Formula: see text] and [Formula: see text] in the test materials as they transition from partially saturated states to a fully saturated state via cycles of water permeation and dewatering. This method does not disturb the test materials, as do the methods associated with traditional laboratory testing on cored samples. It also tests a large mass of in situ material, compared with the small mass tested by the conventional or electromagnetic coaxial transmission line (EMCTL) method (also known as a dielectric cell) and the time-domain reflectometry (TDR) method. Porosity values of asphalt [Formula: see text] and of soils [Formula: see text] were determined by fitting the data into the complex refractive index model (CRIM). Dielectric hysteresis of both soils and asphalt also is observable during the tests and shows that the pathways of water-ingress and water-egress processes are not identical in the plot of [Formula: see text] versus degrees of water saturation [Formula: see text].

The effect of phonon confinement on ground state binding energy of bound polaron in polar quantum wires with a finite confining potential investigated by Landau-Pekar variation technique. The effect of external electric and magnetic fields is taken into account as well. The obtained results show that the polar optical phonon confinement leads to a considerable enhancement of the polaron effect and these corrections increase with increasing of applied fields.
