General relativity (GR) has proven to be a highly successful theory of gravity since its inception. The thrivingly passed numerous experimental tests, predominantly in weak gravity, low relative speeds, and linear regimes, but also the strong-field very low-speed regimes with binary pulsars. Observable gravitational waves (GWs) originate from regions spacetime where is extremely strong, making them unique tool for testing GR, previously inaccessible large curvature, relativistic strong...
A method to interpret the magnetic anomaly due a dipping dike using resultant of horizontal and vertical gradients is suggested. The both vector quantity defined as “complex gradient.” few characteristic points on amplitude phase plots complex gradient are used solve for parameters dike. For uniformly magnetized in earth’s field, plot independent [Formula: see text], index parameter, which depends upon strike dip inclination area. an antisymmetric curve with offset value equal text]. whose...
Detections of gravitational waves emitted from binary black hole coalescences allow us to probe the strong-field dynamics general relativity (GR). One can compare observed gravitational-wave signals with theoretical waveform models constrain possible deviations GR. Any physics that is not included in these might show up as apparent GR deviations. The used current tests describe binaries on quasicircular orbits, since most detected by ground-based detectors are expected have negligible...
In conventional interpretation of electrical resistivity data, either one uses an empirical method (Moore, 1945) or analytical (Tagg, 1934; Roman, Mooney and Wetzel, 1956). While the Tagg, Wetzel systems are based on theoretical considerations, they tedious time‐consuming. The Moore method, while it is very rapid, has disadvantage not yielding absolute values resistivity. Sarma (1963) suggested a modification using Hummel’s (1931) principle, whereby could obtain However seen that, under...
This paper presents the results of a preliminary study on effects sinusoidal magnetic fields percentage germination, growth, and yield cotton (Gossypium species). The covers brief account experimental setup, protocol, essential parameters employed. was carried out using var.spch‐1 seeds having three different germination capacities (Type 1—31%, Type 2—49%, 3—64%). were subjected to with nine frequencies intensities as follows: A. 1 Hz, 100 nT; B. 1500 C. 4000 D. 10 E. F. G. H. I. nT. In 3...
A study of the magnetic anomalies produced by sloping geologic contacts, thin dikes, and horizontal cylinders has revealed that a single relationship exists among created them. The anomaly due to cylinder, first derivative dike, second contact are found be identical in shape. Gay (1963, 1965) presented standard curves interpret over long tabular bodies (1963) (1965). It is shown here same can also used total, vertical contacts.
Gravitational wave (GW) observations of binary black hole (BBH) coalescences provide a unique opportunity to test general relativity (GR) in the strong-field regime. To ensure reliability these tests, it is essential identify and address potential sources error, particularly those arising from missing physics waveform models used GW data analysis. This paper investigates biases tests strong gravitational lensing, an effect not currently incorporated into standard framework for GR tests. In...

Effects of sinusoidal magnetic fields on chawki silkworm rearing have been studied. The experiment was conducted using a multi X Bi hybrid, PM x CSR 2. Disease-free layings were reared from hatching to cocooning and by subjecting first second instar three field frequencies: 0.1, 1.0, 10 Hz at 1500 nT, pp, for six days hours per day. Controls maintained simultaneously. Larval durations both young-stage (I II) late stage (III, IV, V) calculated in hours, including the feeding moulting periods...
The properties of Pc 5 pulsations at Choutuppal (Geomag. Lat.: 7°.5N) near Hyderabad, observed over a period 10 years from 1967 to 1976, are presented. Some the features are: (a) pre-noon maximum in diurnal occurrence pattern, as also amplitude variation (b) decrease around dawn hours. influence level magnetic activity on different is reflected (i) maximisation higher values Kp and (ii) an increase with Kp. long range solar cycle effects these years, involving major portion Solar Cycle No....
The recent publication by Verma and Mallick (1979) on the detectability of an intermediate layer time domain EM sounding provides some informative answers to a problem practical interest. That is, attempt has been made probe usefulness system with regard its ability detect subsurface layer. It is worthwhile analyze same in three‐layer sequence magnetotelluric (MT) which finding increasing use years exploration for minerals (Strangway Koziar, 1979) prospecting geothermal resources (Hoover...
The authors are thankful to Dr. George Keller for pointing out some of the inherent inaccuracies in method proposed by them and especially drawing their attention work already done along same lines. were fully aware, at time presenting this short note, about limitations pointed use Hummel’s principle, that is very approximate also underlying assumptions cannot stand rigorous theoretical tests.
