ABSTRACT: A revised derivation of Hubble's Law by Wu's Spacetime Shrinkage Theory is proposed. The methodology of the derivation is discussed in detail. Because that Hubble's Law can be successfully derived from Wu's Spacetime Shrinkage Theory, instead of Acceleration Doppler Effect, the expansion of the universe can also be interpreted by Wu's Spacetime Shrinkage Theory due to aging of the universe with no concern of dark energy.

ABSTRACT: The well-established powerful ion beam analytical technique, particle induced X-ray emission (PIXE) has been utilized for the determination of the elemental concentration of soil of Savar EPZ area, Dhaka. In this work 9 soil samples have been collected from different location of Savar EPZ area. The adequate modernized facilities available in the accelerator laboratory of Atomic Energy Centre (AEC), Dhaka have been used for the research work, from sample preparation to data analysis and also for research writing. The proton beam energy 2.2 MeV and the current range 10-15 nA are used in my experiments. Microprocessor control Freeze Drying system, Oven (0-220 V), Microbalance and pellet maker have been used for sample preparation. A [Si (Li)] detector with associated other equipments such as amplifier, pre-amplifier, MCA Buffer, PC are used for data acquisition.....

ABSTRACT: According to Yangton and Yington Theory, a single beam Redshift can be explained nicely by Principle of Correspondence in which the amount of unit quantity of a corresponding identical object or event remains constant in all equilibrium states. However, a wide spectrum Redshift can only be interpreted by combining both Principle of Correspondence and Principle of Parallelism in which the correlation between the unit quantities of two different corresponding identical objects or events maintains constant in all equilibrium states. In this paper, a step by step derivation and a thorough study of the Redshift phenomena based on these two principles are discussed.

Keywords : Yangton and Yington Theory, Wu's Pairs, Wu's Spacetime Theory, Wu's Spacetime Shrinkage Theory, Redshift, Principle of Correspondence, Principle of Parallelism.

ABSTRACT: Lithology and reservoir fluid studies based on conventional interpretation paradigms, such as low Vp /Vs values indicating gas presence. Cross plotting appropriate pairs of attributes so that common lithologies and fluid types generally cluster together allows for straightforward interpretation. Five well attributes have been combined to produce three forms of cross plot space; VP/VS-Ratio against IP, Mu-Rho (μρ) versus Lambd-Rho (λρ) and IP versus IS using each well in the field of study (Soku-field) within SOKU-3000 reservoirs. The P-impedance (IP), VP/VS-Ratio, and the lames' parameters (μρ, λρ) were found to be most robust in lithology and fluid discrimination within the reservoirs. In the Soku-field cross plot analysis, indicate the lowest values of VP/VS-Ratio (1.900 - 2.075), IP (6500 - 7500), λρ (21 - 25), and μρ (9 -15). However, the low value of VP/VS-Ratio, IP, λρ, and μρ perhaps IS corresponds to hydrocarbon (Gas) saturation within the fields of study. The high value of all these parameters might be due to shales/wet sands intercalations......

ABSTRACT: Length Contraction is a phenomenon interpreted all along by Einstein's special relativity. However, it has never been explained explicitly. In this paper, the visual path of the photon traveling from the end of the object to the observer which defines the visual distance (observed by observer's eyes) between the object and the observer is proved equal to the vision of light from the observer to the end of the object. As a result, both Length Contraction and Expansion can be expected subject to observer's traveling direction and speed with respect to the object...

ABSTRACT: Building materials are one of the potential sources of indoor radioactivity because of the naturally occuring radionuclides in them. External as well as internal exposures are the two pathways of radiation dose imparted to the human beings from the building materials. Natural radioactivity levels of 35samples of natural and manufactured building materials used in Kuthua area, J&K have been investigated by using gamma spectrometer with NaI(Tl) detector. The samples were collected from local market and construction sites. From the measured γ-ray spectra, activity concentrations were determined. The activity ranged from 12.7 ±3.4 to 38.4 ±4.4 Bqkg-1 for 226Ra, from 13.2±0.7....
