Abstract: A logistic was derived by Mr H.C. Rajpoot in March, 2010 which was formulated in a generalised form by him in Feb, 2014 by using some arbitrary terms to deal with complex problems of linear permutations. It is used to find out the correct order (called rank) of any randomly selected (or a given) linear permutation (like words, numbers & all other linear permutations) from a set of all the linear permutations arranged in a correct order (sequence). It is an expansion (series) formula of which each term corresponds to a certain article of any linear permutation. It is also applicable to position the linear permutations in correct order provided that the articles have at least one easily distinguishable property like appearance in shape, size, colour, surface-design etc. & all are equally significant at all the places (positions) in all possible linear arrangements. For ease of understanding, for a given alphabetic word or a positive integral number with ‘n’ letters or non-zero digits respectively. It has three new arbitrary parameters as  which are expanded in a finite series. The values of these parameters depend on former (leading) articles, permutations of successive articles &repeatability of article, &The number of terms in that series is equal to total no. of articles (like letters, digits etc.) in any linear permutation (like word, number etc.).

Keywords: Linear permutation,

Abstract: Limnological studies of lower lake include comparison of water quality parameters of two different sites of the lower lakes namely Kali Mandir and Neelam Park in every month at surface and bottom level of lower lake, Bhopal during 2012. Water sample collected were analyzed for their limnological characters viz. temperature, pH, conductivity, total hardness, TDS, DO, BOD, COD, total alkalinity, chloride, sulphate and nitrate. Data obtained from these analyses were analyzed and it reveals that quality of lower lake water changes and need proper monitoring.

Keywords: Limnological, lower lake, conductivity, total hardnesss, total alkalinity

Abstract: The title of my Theory is called as acids-bases Theory. The purpose of my Theory is finding acids and bases with their strength in organic and inorganic fields of chemistry. This Theory explains characteristics, properties, relation, structure, strength, neutralisation of acids-bases. And also it explains classification of acid-bases like covalent acid bonds, dative acid bonds, and ionic base bonds. Salt is defined as additional product formed by neutralisation. Strength of acids and bases defined in terms of electronegativity and electropositivity of atoms or molecules.

Keywords:  Electronegativity, Electropositivity, chemical bonds, valency electrons, and ions.

Abstract: The amounts of radioactivity in the igneous rocks have been investigated; 63 basalt rock samples were collected from Aden governorate, south of Yemen. The activity concentration of ²²⁶Ra, ²³²Th and ⁴⁰K were measured using NaI (TI) detector. Along the study area the radium equivalent activities Ra_eq in Bq/Kg of samples under investigation were found in the range of 51.60to 809.26Bq/Kg with an average value of 237.01Bq/Kg, this value is below the internationally accepted value of 370 Bq/Kg. To estimate the health effects of this natural radioactive composition, the average values of absorbed gamma dose rate D (55 nGyh^-1), Indoor and outdoor annual effective dose rates E_ied (0.11 mSvy^-1), and E_oed (0.03 mSvy^-1), External hazard index H_ex(0.138) and internal hazard index H_in (0.154), and representative level index I_γr(0.386) have been calculated and found to be higher than the worldwide average values.

Keywords: South Yemen, Absorbed gamma dose, activity concentration, igneous rocks, NaI (TI).

Abstract:  We use the Newton’s law of gravitation as an entropic force to study some thermodynamical properties of a system of two Schwarzschild black holes which are immersed in a background temperature. For this we assume the two black holes are at large separation distance. We extract entropy, free energy and internal energy of the system. Positive definiteness of the free energy leads to a limit on the black holes temperatures.
