Evolution of High Yielding, Early Maturing and CLCuV Resistant Mutant of Cotton NIAB-98, Through the Use of Pollen Irradiation Approach
M. Aslam
Plant Pathology Journal , 2002,
Abstract: The locally well adapted cotton variety NIAB-78 was crossed with an exotic line REBA-288 with male parent pollen irradiated at 10 Gy of gamma rays before cross-pollinations to develop M0 seed. The M2 population was grown from M1 seed and different desirable mutants having higher yield, early maturity, short internode, resistant to CLCuV disease etc. were selected. These mutants were evaluated for yield potential and other economic traits in different segregated generations till uniformity was achieved. Of these the mutant PIM-76-8, later named as NIAB-98 was finally selected. The mutant NIAB-98 has a medium sized plant with suitable plant type and better leaf foliage. It is moderately hairy, early maturing, heat tolerant, has high yield potential and has acceptable fibre characteristics. At NIAB on the average, NIAB -98 gave 35.1 % higher yield than CIM-443, 9.1% higher yield than NIAB-Karishma, 35.8 % higher yield than CIM-482 respectively during the years 1998-99 to 2001-2. At farmers fields (3 years average) it gave 21.0, 16.1, 9.2 29.9 and 16.9% higher yield than CIM-443, NIAB-Karishma, CIM-482, CIM-446 and FH-900 was respectively during the years 1999-2002. In NCVT and DCR trials conducted by PCCC, Karachi and Director Cotton Research Institute Faisalabad, it showed wider adaptability right from Faisalabad down towards Sindh by ranking 4th in the NCVT -2000-2001 and in the DCR trials ranked 7th during 2000-2001 and 2nd during 2001-2002 respectively in the said trials. Moreover it showed early maturity, heat tolerance, relatively better tolerance to bollworms, particularly pink bollworm. It can escape the peak attack of the same due to its early maturity. It has higher oil and protein contents i.e. 24 and 28% respectively than leading/standard cotton varieties (CIM-433, CIM-446, CIM-482, CIM-473 and FH-900).
On Subsets of Q(√m) Q under the Action of Hecke Groups H(λq)  [PDF]
M. Aslam Malik, M. Asim Zafar
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.58120
Abstract:

\"\" is the disjoint union of \"\" for all \"\", where \"\" is the set of all roots of primitive second degree equations \"\", with reduced discriminant \"\" equal to k2m. We study the action of two Hecke groups—the full modular group \"\" and the group of linear-fractional transformations \"\" on \"\". In particular, we investigate the action of \"\" on \"\" for finding different orbits.

Association of Rainfall and Stability Index with Lightning Parameter over the Indo-Gangetic Plains  [PDF]
M. I. R. Tinmaker, M. Y. Aslam, D. M. Chate
American Journal of Climate Change (AJCC) , 2017, DOI: 10.4236/ajcc.2017.63023
Abstract: The Lightning Imaging Sensor (LIS) based satellite lightning grid data for 10 year period (1998-2007) were used to study the association of rainfall and stability index with lightning parameter over Indo-Gangetic plain (IGP) region. The spatial variation of flash rate density (FRD) is found to be (40 fl·km-2·yr-1) higher over northern region of IGP as compare to that of eastern IGP region. The annual variation of FRD exhibits bimodal distributions, while the precipitation rate shows unimodal distributions. The results show that the FRD peaked 2 months (pre-monsoon) in advance to the monsoon months where rainfall peak occurred due to environmental lapse rates more than 7.0°C/km during pre-monsoon which is evident from the temperature profile for correlation coefficient between temperature (700 mb) and FRD with coefficient of 0.70, p ≤ 0.0001 during pre-monsoon. The annual variation of lifted index show negative value over March to September due to intense insolation, convective available potential energy (CAPE) and also availability of moisture. The convective cloud transform into thundercloud with the development of mixed-phase (cloud water + ice) which subsequently produce the lightning. During monsoon, seasonal thermal heating diminishes and even on revival after break monsoon period, K-index is found to be less as the orography does not allow the highly moist air of low temperature to reach to large height above freezing level. They can be referred as maritime clouds of intermediate height with moderate updraft and hence minimum lightning activity during the monsoon season. Lifted index are proved to be indicators of thunderstorm conditions. This is because that rising air parcel is much warmer than its surroundings and can accelerate rapidly and create severe thunderstorms.

On mixed finite element techniques for elliptic problems
M. Aslam Noor
International Journal of Mathematics and Mathematical Sciences , 1983, DOI: 10.1155/s0161171283000642
Abstract: The main aim of this paper is to consider the numerical approximation of mildly nonlinear elliptic problems by means of finite element methods of mixed type. The technique is based on an extended variational principle, in which the constraint of interelement continuity has been removed at the expense of introducing a Lagrange multiplier.

International Journal of Mathematics and Mathematical Sciences , 1981, DOI: 10.1155/s0161171281000410
Abstract: For piecewise linear approximation of variational inequalities associated with the mildly nonlinear elliptic boundary value problems having auxiliary constraint conditions, we prove that the error estimate for u ¢ ’uh in the W1,2-norm is of order h.

Analele Universitatii Bucuresti : Chimie , 2009,
Abstract: The root and stem bark of Feronia limonia yielded 5, 7-dihydroxy-3', 4'-dimethoxy -6, 8-di (3-methylbut-2-enyl) flavanone along with several known compounds viz., stigmasterol, friedelin, β-sitosterol-3-O-β-D-glucopyranoside, bergapten, xanthotoxin, scopoletin, isoimperatorin, osthol and 6, 7-dimethoxycoumarin. These compounds were characterized on the basis of U.V, IR, N.M.R (1H, 13C) and mass spectral studies.
Transformation of the extended Gamma function $Γ^{2,0}_{0,2}[(b,x)]$ with applications to astrophysical thermonuclear functions
M. Aslam Chaudhry
Physics , 1998,
Abstract: Two representations of the extended gamma functions $\Gamma^{2,0}_{0,2}[(b,x)]$ are proved. These representations are exploited to find a transformation relation between two Fox's $H$-functions. These results are used to solve Fox's $H$-function in terms of Meijer's $G$-function for certain values of the parameters. A closed form representation of the kernel of the Bessel type integral transform is also proved.
Topology On BCK-Modules
Agha Kashif,M. Aslam
Mathematics , 2015,
Abstract: In this paper, we introduce the notion of a BCK-topological module in a natural way and establish that every decreasing sequence of submodules on a BCK-module M over bounded commutative BCK-algebra X is indeed a BCK- topological module. We have defined the notion of compatible and strict BCK- module homomorphisms, and establish that a strict BCK-module homomorphism is an open as well as a continuous mapping. Also, we establish the necessary and sufficient condition for a compatible mapping to be strict.
