When astrologers fail double-blind tests, supporters often defend astrology by implying the failure is that of the astrologers rather than astrology itself. Empirical research sheds light on the matter.

Article published in The Skeptik on 18 June 2021. https://www.skeptic.org.uk/2021/06/when-put-to-the-test-the-predictive-powers-of-indian-astrology-simply-dont-hold-up/ This work is continuation of the research published in Skeptical Inquirer by Narlikar et al on double blind test of Indian astrology. In this test, none of the astrologers could...

This article examines few fundamental principles of Vedic astrology through a systematic empirical experiment conducted on the birth charts of people who have suffered from cancer and people who have never had it in their life. Two data sets were formed, one consisting of 254 birth charts of people who were diagnosed with cancer before the age of 6...

Abstract This article examines few fundamental principles of Vedic astrology through a systematic empirical experiment conducted on 742 birth charts of people who have been celebrities and 509 charts of people who have not been celebrities and have led ordinary lives. Each of the 21 fundamental principles of Vedic astrology we tested was found to b...
Article
Measurements of secondary electron emission coefficient and surface work function phi are reported for polyacrylonitrile (PAN) and polytetrafluoroethylene (PTFE) in the virgin and chemically modified forms. A single pulse method was used for SEE measurements and a retarding field method for estimating the work function. Doping of PTFE with alkali m...
Article
This paper presents a case report where the soldered joints of Microwave Integrated Circuits were accidentally contaminated with nitric acid. On meeting with an accident a decision on whether to accept the assembled box is very crucial, particularly in complicated and high reliability hardware, where a high cost and numerous efforts of inspection a...
Article
Changes in gap state distribution due to defects induced by different doses of 10‐keV electrons in phosphorous‐doped a‐Si:H are reported. These defects have been observed qualitatively by electron beam writing. Patterns thus generated were read by electron beam induced current (EBIC). The increased local recombination in the area results in the dec...
Article
A new method for directly monitoring the electron beam intensity profile in a scanning electron microscope is proposed. This method employs phase lock‐in technique which electronically differentiates the integrated current collected, while scanning the rocked electron beam across a knife edge and directly obtains the one‐dimensional intensity distr...
Article
This paper presents the application of the EBIC contrast width measurement technique for the verification of simulated electron beam exposure widths. The measurements were performed on p-i-n configuration of a-Si:H, as a case study, at various exposure conditions. The measured values of EBIC contrast width were compared with the widths of simulated...
Article
Hydrogenated amorphous silicon (a-Si:H) samples were exposed to an electron beam at various beam energies and doses, causing damage. The exposed image and spot patterns were studied using the SEM-EBIC technique. The dependence of EBIC image contrast on the exposing electron beam energy and dose and its annealing behaviour are studied. The contrast...
Article
Secondary electron emission (SEE) has been investigated for reduced Pb glass and bismuth containing V2O5P2O5 and silicate glasses. The measurements of SEE coefficient, surface work function and ionization potential are reported. The systematic analysis of these results using Dionne's theory is given in view of their application in an electron mult...
Article
The energy distribution of localized states was determined in undoped and PH3 doped a-Si:H from frequency resolved EBIC measurements. The experiments are based on the theory developed by Oheda for the analysis of phase shift between sinusoidally modulated exciting light and its induced photocurrent. In the present attempt the photocurrent measureme...
Article
Lead zirconate titanate (PZT) is known to become a semiconductor after reduction in a hydrogen atmosphere. An attempt is made here to characterize the reduced, as well as the unreduced, PZT system with the help of photoacoustic (PA) spectroscopy and X-ray photoelectron spectroscopy (XPS) and to obtain useful information regarding its electronic beh...
Article
The ionization potential and work function of plasma-polymerized zcrylonitrile thin films have been measured using a low energy electron gun in an ultrahigh vacuum system. The optical absorption and electrical resistivity were also measured as a function of pyrolization temperature and doping. A change in ionization potential, work function, electr...

Article
Electrical conductivity in lead zirconate titanate ceramic containing niobium oxide as impurity showed a marked increase when it was reduced in hydrogen atmosphere. X-ray photoelectron spectra were used to investigate the chemical behaviour of the reduction products. Depth profiling for reduced Nb-doped PZT indicated the presence of metallic Pb, wh...

A study of electron emissive characteristic is presented for bismuth containing vanadium pentoxide and silicate glasses. Measurements of yield in secondary electron emission (SEE) were performed incorporating a retarding field analyzer and the other related parameters such as work function and ionization potential were measured using a low energy e...
Article
Coefficients of ion induced secondary electron emission (ISEE) γ from thin films of Al2O3 and MgO have been measured for argon ions in the energy range between 0–3 keV. Dionne's equation for secondary electron emission, which consists of production and emission terms has been modified to explain the kinetic emission of ISEE. The production term for...
Article
Secondary electrom emission yield () and the surface work function values () were measured for lead zirconium titanate (PZT) doped with lanthanum, strontium, and niobium. The single pulse method was used in LEED/Auger geometry for measuring the secondary electron emission yield while the retarding potential technique was employed for measuring the...
Article
A comparative study of electron emission characteristics was made for thin films of Al2O3 deposited by the techniques of r.f. sputtering, chemical vapour desposition and post-oxidation of vacuum-evaporated aluminum films. A single pusle method was used with a retarding field analyzer for measurement of the yield in secondary electron emission. Rela...

Secondary electron emission yieldδ was measured for thin films of alumina prepared byrf sputtering technique. Single pulse method was used along with 4-gridleed optics system to determineδ. Maximum value of 4·3 was obtained at primary energy of 350 eV. The Dionne’s theory was used to analyse the results and the emission probability escape depth and...

Question
What are the regulations for online computerized psychological assessments?
Online (free) assessments are nothing but an algorithm that makes the scoring and interpretation easier and accessible. It helps people take a decision whether they should go to a doctor for consultation, plan their therapy etc. However is that kind of online assessment allowed as per regulations?
Question
It is observed that there is a substantial diversity in a class of Engineering college in terms of learning ability of students. This could be partially due to diverse background of students (rural, semi-urban, urban), varied proficiency over English language which is medium of teaching and due to different educate systems they come from. Is there any psychological assessment that will help the college authorities to segregate slow, average and fast learners in a given class?
Question
In India, 80% marriages are arranged marriages and since there is no scientific method available to check the overall compatibility (especially from psychological perspective) people use unscientific methods like astrology. Is there any psychological assessment to test compatibility of Indian bride and grooms?
Question
Can someone share experience of conducting an online test for college students in mass (by college or NGOs) with an objective of identifying depression or Bi-polar probables? Does this work? Which test is used?

Project
Project objective is to detect psychological disorders like depression, anxiety, Bi-polar in early stage among college students. Various online psychological assessments will be launched through technology based tools and tests will be conducted in collaboration with college authorities. Those who are identified as probables from these tests will be further scrutinized through psychiatrists.
