Assessment of Toxicity of Some Penta- and Hexacoordinated Organotin(IV) and Tetracoordinated Tin(II) Complexes of Heterocyclic -Diketones
Asha Jain,Sanjiv Saxena,Audhesh K. Rai,Prabhu N. Saxena
Bioinorganic Chemistry and Applications , 2006, DOI: 10.1155/bca/2006/60140
Abstract: A number of penta- and hexacoordinated organotin(IV) complexes and tetracoordinated tin(II) complexes of compositions Me2SnCl[RCOC:CON(C6H5)N:C︹CH3] (where R=−CH3, −p−ClC6H4, and −C6H5), Me2Sn[RCOC:CON(C6H5)N:C︹CH3]2 (where R=−CH3, and −C6H5), and Sn(II) [RCOC:CON(C6H5)N:C︹CH3]2 (where R=−p−ClC6H4 and −C6H5) were screened for their toxicity against Musca domestica (house fly). In general, organotin(IV) complexes contribute more to the activity than tin(II) complexes.

Unresolving pericarditis: Suspect filariasis in the tropics
Prasanthi K,Nagamani K,Saxena N
Indian Journal of Medical Microbiology , 2010,
Abstract: Filariasis, a mosquito-borne disease, is wide spread in India. While laboratory diagnosis has been conventionally done by demonstrating microfilaria in peripheral blood smears, occasionally they are reported in various body fluids including pericardial fluid. We report the case of 33-year-old man with severe dyspnoea and chest pain, referred from a private nursing home with a provisional diagnosis of unresolving pericarditis. Pericardial tap revealed massive pericardial effusion with actively motile microfilariae. No microfilariae (Mf) were seen in the peripheral blood. Haemorrhagic effusion resolved completely with DEC. Though relatively uncommon, tropical diseases must always be considered in the etiological diagnosis of pericardial effusion.
Application of computational intelligence in emerging power systems
D Saxena, S.N Singh, K.S Verma
International Journal of Engineering, Science and Technology , 2010,
Abstract: Electric power systems, around the world, are changing in terms of structure, operation, management and ownership due to technical, financial and ideological reasons. Power system keeps on expanding in terms of geographical areas, assets additions, and penetration of new technologies in generation, transmission and distribution. This makes the electric power system complex, heavily stressed and thereby vulnerable to cascade outages. The conventional methods in solving the power system design, planning, operation and control problems have been very extensively used for different applications but these methods suffer from several difficulties due to necessities of derivative existence, providing suboptimal solutions, etc. Computation intelligent (CI) methods can give better solution in several conditions and are being widely applied in the electrical engineering applications. This paper highlights the application of computational intelligence methods in power system problems. Various types of CI methods, which are widely used in power system, are also discussed in the brief.

Abstract: A number of penta- and hexacoordinated organotin(IV) complexes and tetracoordinated tin(II) complexes of compositions Me 2 SnCl[ RCO C:CON( C 6 H 5 )N:C ︹ CH 3 ] (where R= CH 3 , p ClC 6 H 4 , and C 6 H 5 ), Me 2 Sn [ RCO C:CON( C 6 H 5 )N:C ︹ CH 3 ] 2 (where R= CH 3 , and C 6 H 5 ), and Sn(II) [ RCO C:CON( C 6 H 5 )N:C ︹ CH 3 ] 2 (where R= p ClC 6 H 4 and C 6 H 5 ) were screened for their toxicity against Musca domestica (house fly). In general, organotin(IV) complexes contribute more to the activity than tin(II) complexes.
Pulmonary tuberculosis: A comparative study of conventional methods and serological diagnosis
Mohammed Khaleel,N. K. Saxena,V. C. Kishore Reddy
Journal of Medical and Allied Sciences , 2011,
Abstract: The objective of the study was to evaluate mycobacterial identification and isolation rates obtained by different conventional methods. Sputum and serum samples were taken from 80 clinically diagnosed pulmonary tuberculosis (PTB) cases. Smear microscopy alone showed an efficacy of 85%, culture 90% and serology 72.5%, in diagnosis of PTB. The efficacy of smear microscopy increased by examining more than one sputum sample to about 98%. The correlation between smear, culture and serology was assessed. Further investigation of smear-negative cases with culture examination was done. Concomitant x-ray studies delineated the location and extent of the lesion, mostly exudative type confined to upper zone. The culture isolates subjected to drug susceptibility test, showed 27% multi-drug resistant strains.
Comparison of ILMA Guided Tracheal Intubation in the Lateral Position with the Supine Position
Manish Naithani, Kirti N Saxena, Prachi Gaba, C K Dua
Asian Journal of Medical Sciences , 2012, DOI: 10.3126/ajms.v3i4.5667
Abstract: Background: The ILMA has been established as a valuable airway management device in the supine position, in both elective and emergency situations, for both ventilation and intubation. Intubation in lateral position might be necessary in some congenital syndromes, morbid obesity, or after accidental extubation in laterally positioned patients. This study was undertaken to evaluate the ILMA for intubation of patients in the lateral position and compare it with intubation in the supine position.
Signatures of Heavy Z-prime in the Extra U(1) Superstring Inspired Model: RGEs Analysis
Saxena, Pranav;Parashar, Prachi;Sharma, N. K.;Nagawat, Ashok K.;Singh, Sardar
High Energy Physics - Phenomenology , 2007,
Abstract: In the extra U(1) superstring inspired model, we examine the electroweak and U(1)-prime symmetry breaking with the singlet and exotic quark D, D+{\c}along with the study of heavy Z-prime boson in accordance with the top quark mass region. For this, we have done the analysis of complete renormalization group equations (RGEs)pertaining to the anomaly free E-{\6}-Eta model of rank 5. The Z-prime is found to the order of TeV or above with allowed small Z-Zprime mixing angle, for which the large singlet VEV is required. This is done by considering the only non-universality of Yukawa couplings at GUT scale because these do not obey the E-{\6}relationship and also satisfies the unitarity constraints both at GUT and weak scale, where rest of the parameters, i.e., gaugino masses, tri-linear couplings, and soft supersymmetric breaking masses are kept universal at GUT scale with the gauge couplings unification. The large value of Yukawa couplings (order of 1) triggered the symmetry breaking radiatively and induces the effective-Mu parameter at the electroweak scale and lead to a viable low energy spectrum at weak scale.

Indian Streams Research Journal , 2012,
Abstract: The conceptual understanding of fundamental topic like electromagnetism in Physics is much depends upon cognitive developments of students. These cognitive beliefs affect the conceptual understanding of such fundamental subject. This research is based on surveys made on the learners of First Year, Second Year, and Third Year, B.Sc. students of K J Somaiya College of science and commerce, Mumbai, which is centrally, placed 'A' grade College. The learner's characteristics of undergraduate students were quantified using different techniques. The students were undergraduate students studying basic sciences having physics as there one of major subject in 10+2+3 pattern in Mumbai University, India.
Measurement of velocity of Ultrasonic sound in alkali halide R R solutions with different Normality
J. K. Pendharkar,S. K. Saxena,Yogesh Ghalsasi,M. N. Nyayate
Review of Research , 2012,
Abstract: Velocity of sound in solutions is very large as compared to that in air, and this velocity is density dependent. In this experiment the alkali halide solutions of different normality was prepared and the velocity of sound was observed using Ultrasonic Interferometer at 2 M Hz of frequency. The velocity of sound was observed to be increasing with increasing Normality of solutions except for the potassium iodide solution, where this change is marginal. As an extension to this experiment sodium halide solutions were tested, and again the change in Sodium iodide was observed to be much less. This showed that the velocity of sound in alkali halide solutions was observed to be frequency dependent also that is at certain frequency for a solution velocity remains almost constant with change in normality.
