Building a Geodatabase for Parcel and Cadaster Mapping and Add-Ins Development: A Case Study for Defense Housing Authority (DHA), Lahore, Pakistan  [PDF]
Mamoon Ur Rasheed, Sajid Rashid Ahmad, Rashid Saleem
Journal of Geographic Information System (JGIS) , 2015, DOI: 10.4236/jgis.2015.76047
Abstract: This paper presents a systematic view of most up-to-date tools, technologies and techniques which is appropriate not only for effective decision making, but also helpful for competent administration to provide efficient resolution for spatial troubles of Khasra and Parcel management. Different Data collection techniques have been applied on different data sources. Worldview II of 0.5 resolution image, scanned Master Plan and Cadastral/Khasra Maps was used for development of geodatabase for spatial and non-spatial entities using ArcGIS 10.2. Multiple processing on Satellite Imagery using ERDAS Imagine was performed like Image enhancement, Mosaicking and Color Balancing, Image Geo-referencing and Raster Cataloging. Development of Customize Graphical User Interface (GUI) for DHA’s officials and administrator makes efficient decision in society matters. This is the first spatial GUI, for DHA to plan and maintain society’s activities efficiently, in the form of ArcMap Add-Ins. These Add-Ins are written in C#.Net using ArcObjects APIs within MSVS 2012.
Quality and Mechanical Properties of Plant Commercial Fibers
Sultana Rasheed,Altaf Ahmad Dasti
Pakistan Journal of Biological Sciences , 2003,
Abstract: Twenty-four different plant species belonging to 19 families were analyzed in the current investigation. Plants were ranked according to the felting power, suitability of fibers and strength of the fibers. Among monocots, Caryota urens (garden palm) and Eucalyptus camadulensis, in dicotyledonous plant species had the strongest fibers. Caryota urens (garden palm) in monocots while Terminalia arjuna in dicots had high felting power. Cluster analysis had separated out the Agave americana in monocot which was significantly apart from Saccharum spontaneum, on the basis of derived characters like Slenderness ratio, Runkle ratio and Coefficient of suppleness. Phoenix dactylifera was dominant due to its great fiber length and lowest Runkle ratio. In this investigation, it was concluded that different plant species can be used for different purposes and evolution does not necessarily involve all the qualities of fibers at the same time.
Adsorption of copper and lead in single and binary metal system onto Fumaria indica biomass
Munawar Iqbal, Rasheed Ahmad Khera
Chemistry Internatioanl , 2015,
Abstract: Among heavy metals, lead and copper pose a significant threat to the due to their toxicity, incremental accumulation in the food chain and persistence in the ecosystem. Lead and copper are introduced into water from various industries and other human activities. Present study was aimed to remove lead and copper from aqueous media using Fumaria indica biomass as a function of metal ions initial concentration. Both metal removal was investigated in single and binary system. For comparison isotherm models i.e., Langmuir and Freundlich were applied on experimental adsorption data. Results showed that the copper behavior was different in single and binary metal system, whereas lead adsorption remained the same in both single and binary metal systems. The Freundlich isotherm model fitted well to the adsorption data of both single and binary metal system. The thermodynamic parameters i.e., ?G0, was measured to get insight into adsorption phenomenon and negative value of ?G0 suggest that the adsorption process was spontaneous in nature. Results showed that in multi-metal system the adsorption of specific metal ion may change and during metal adsorption from industrial wastewater this effect must be taken in account before generalization of results.

Asian Journal of Information Technology , 2012,
Abstract: Trust is a vital ingredient that contributes to the successful online business. Despite the richness of trust in e-commerce literature, only few of it focuses on developing countries. Drawn from previous literatures on trust in e-commerce transactions, this study proposed a new framework for investigating trust in online shopping, which focused on Pakistan, one of the developing countries. This study attempts to investigate the role of trust in Internet shopping among Pakistan`s nations.

Aamer Saeed,Rasheed Ahmad Khera,Masood Parvez
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810004708
Abstract: The asymmetric unit of the title compound, C14H18N2S, contains two independent and conformationally similar molecules, which form cyclic dimers via intermolecular hydrogen bonds of the type N—H...S [graph set R22(8)]. The structure is isomorphous with that of one of the polymorphs of 4,4,6-trimethyl-1-phenyl-3,4-dihydropyrimidine-2(1H)-thione [Yamin et al. (2005). Acta Cryst. E61, o55–o57].
N-(2-Fluorophenyl)cinnamamide
Aamer Saeed,Rasheed Ahmad Khera,Jim Simpson
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810003867
Abstract: The title compound, C15H12FNO, was prepared by the reaction of cinnamoyl chloride with 4-fluoroaniline and crystallizes with two molecules A and B in the asymmetric unit. The two unique molecules are closely similar and overlay with an r.m.s. deviation of 0.0819 . The fluorobenzene and phenyl rings are inclined to one another at 73.89 (7) and 79.46 (7)°, respectively, in molecules A and B. The amide C—N—C(O)—C portions of the molecules are planar (r.m.s. deviations = 0.035 and 0.028 ) and are inclined at 45.51 (9) and 47.71 (9), respectively, to the fluorobenzene rings in molecules A and B. The 2-fluoroacetamide units and the benzene rings each adopt E configurations with respect to the C=C bonds. In the crystal structure, intermolecular N—H...O hydrogen bonds augmented by weak C—H...π interactions link molecules into rows in a head-to-tail fashion along a. Additional weak C—H...O contacts further stabilize the packing, forming a three-dimensional network stacked down a.

Aamer Saeed,Rasheed Ahmad Khera,Jim Simpson
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810010378
Abstract: The title compound, C15H15NO, (I), is a polymorph of the structure (II) reported by Gowda et al. [Acta Cryst. (2008), E64, o1494]. Compound (II) crystalllizes in the space group C2/c (Z = 8), whereas the title compound occurs in space group P21/c (Z = 4). The two molecular structures differ slightly in the relative orientations of their central amide group with respect to the benzoyl ring [dihedral angles of 55.99 (7) for (I) and 59.96 (11)° for (II)] and in the inclination of the benzoyl and aniline rings [88.67 (8) for (I) and 81.44 (5)° for (II)]. In the crystal structure of (I), molecules are linked by N—H...O hydrogen bonds, forming C(4) chains, which are augmented by weak C—H...O interactions. The structure is further stabilized by C—H...π contacts involving both of the aromatic rings.
4-Chloro-N-(2-methoxyphenyl)benzamide
Aamer Saeed,Rasheed Ahmad Khera,Jim Simpson
Acta Crystallographica Section E , 2010, DOI: 10.1107/s160053680905394x
Abstract: The title compound, C14H12ClNO2, was prepared by refluxing 4-chlorobenzoyl chloride with o-anisidine in CHCl3. The methoxyphenyl–amide segment of the molecule is almost planar, with a dihedral angle of 5.10 (7)° between the benzene ring and the C—N—C(O)—C fragment. A weak intramolecular N—H...O contact forms an S(5) ring and contributes to the planarity of this portion of the molecule. The two benzene rings are inclined at an angle of 26.74 (7)°. In the crystal structure, intermolecular Cl...O interactions of 3.1874 (9) generate centrosymmetric dimers. These are further linked by C—H...O and C—H...π interactions, forming inversion related sheets parallel to [001].

Journal of Medical Sciences , 2004,
Abstract: Present study was planned to investigate iodine intake and thyroid hormone concentration in normal pregnant women during first trimester of pregnancy in Lahore. Urinary iodine concentration, free T4, T3 and TSH of pregnant women were determined and compared with that of control women. Results showed that most of the control and pregnant women in this study were mild to moderate deficient in iodine intake. The median level of urinary iodine concentration was 70 and 75 μg L-1 in pregnant and control, respectively. In all the pregnant women FT4 level were towards lower limit of control`s normal range. The mean T3 level in pregnant women was raised as compared to control. 34.7% of pregnant women had T3 levels above upper limit of normal range. The mean TSH level was slightly lower in pregnant women as compared to control. Eight percent of pregnant women had undetectable TSH (0.05 mlU L-1). Only three women had TSH above upper limit of normal range.
