Revisiting the Art of Collaboration in the Age of Internet
Saadat M. Alhashmi,Jawed Siddiqi
Communications of the IBIMA , 2008,
Abstract: The paper establishes the necessity for collaboration for effective supply chain management in the age of Internet. In a networked society where everything is connected, collaboration is the word visited and revisited every now and then. How can we collaborate to optimize resources efficiently? This paper briefly explores some enablers, obstacles for supply chains and proposes some basic components of a strategy for enabling and overcoming these obstacles. A brief discussion of the benefits that go beyond the bottom line, including customer demands and personalisation are noted. Focus of this paper is on the collaboration within the context of supply chain management.
Towards a Framework for Federated Global Identity Management
Mehrdad Naderi,Jawed Siddiqi,Babak Akhgar,Wolfgang Orth
International Journal of Network Security , 2008,
Abstract: This paper reports on research being conducted into the formulation of the architectural blueprint necessary to provide a Global identification service across global ICT infrastructures integrating that of the Web and the Grid and introducing the concept of what the EU IST Framework V initiative refers to as 'protected GC infrastructure'. Such a platform implies a secure vertical integration between heterogeneous grid platforms but more significantly creates the condition for horizontal integration i.e. interoperability of various global infrastructures (the Internet, the Web and the Grid) with common services i.e the creation of new secure and trustworthy global and interoperable services. The proposed research is both fundamental and highly innovative because the FeGIMa framework manages individual and organizational identification with their disparate security mechanisms. It does so for the variety and diversity of global ICT stake-holders through the formulation of a sufficiently abstract/high-level architectural blueprint that frees them from having to be constrained to the same (i.e. one type fits all) technologies for authentication. For the disparate community of global computing stake-holders the freedom obtained through the proposed technically innovative FeGIMa framework results in the simplicity of "Single Sign on and Single Service Authentication - SSO & SSA" thereby directly contributing to realizing the vision of Information Society for All.
Mineragraphic Study of Manganese Ore Deposits of Kandri, Mansar, Beldongri and Satak Mines, Nagpur District (Maharashtra) Central India  [PDF]
Talat Jawed, F. N. Siddiquie
International Journal of Geosciences (IJG) , 2014, DOI: 10.4236/ijg.2014.57064

In Nagpur, M.P.-Maharashtra Manganese Belt is exposed which is part of Sausar Belt. In Nagpur, four manganese mines viz Mansar, Kandri, Beldongri and Satak are selected for the ore microscopic study. These mining areas are situated in that part of Central India which are highly deformed and metamorphosed and are characterised by high grade amphibolite facies to low grade greenschist facies. The Precambrian manganese ore deposits of Nagpur are formed by the metasediments of Sausar belt which is rich in manganese sediments. The manganese ores of the study area are co-folded with distinct rock types i.e. “gondites” and predominantly composed of a mixture of braunite, bixbyite, hausmannite, hollandite, jacobsite, vredenburgite, pyrolusite, cryptomelane and psilomelane. The dominant rocks are tirodi migmatitic gneiss, argillaceous and calcareous rock types. This paper discusses the mineralogy of the manganese ores of Kandri, Mansar, Satak and Beldongri. After the careful assessment of mineralogy, texture and paragenesis of the manganese ore of the study area, it has been concluded that the manganese ores of the study area are formed by the multiple processes i.e. metamorphism and supergene enrichment. These supergene enrichments are evidence of colloidal influx. Occurrence of free braunite, free hausmannite and free jacobsite indicates the high grade metamorphism. Pyrolusite, rhodonite, and psilomelane-cryptomelane are formed by supergene enrichment. The presence of lamellar twinning in braunite indicates about shear pressure. In this area the different manganese mineral assemblages and their textures suggest about the occurrence of different metamorphic activity and depositional environment. The texture and paragenesis of manganese ore of the study area are discussed here.

The m-Point Quaternary Approximating Subdivision Schemes  [PDF]
Shahid S. Siddiqi, Muhammad Younis
American Journal of Computational Mathematics (AJCM) , 2013, DOI: 10.4236/ajcm.2013.31A002

In this article, the objective is to introduce an algorithm to produce the quaternary m-point (for any integer m>1) approximating subdivision schemes, which have smaller support and higher smoothness, comparing to binary and ternary schemes. The proposed algorithm has been derived from uniform B-spline basis function using the Cox-de Boor recursion formula. In order to determine the convergence and smoothness of the proposed schemes, the Laurent polynomial method has been used.

Temporal change assessment of agricultural land by Satellite Remote Sensing (SRS) technique  [PDF]
Gohar Ali Mahar, Razzaq Ahmed, Mohammad Jawed Iqbal
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.56085

Agriculture is the vital economic activity of rural society in nearly all of Pakistan. The Winder-Sonmiani area located at the Makran coast near the city of Hub in Pakistan is economically very promising. Cropping, horticulture, fruit farming and animal husbandry are the common land use activities in the area while fishing along the coast is an important economic activity. Owing to the use of the Satellite Remote Sensing technique (SRST), the triangular basin shape structure of the Winder area has been found to be spatially very promising for agricultural activities. Positive change in the use of agriculture land was detected from the Satellite images of different periods. Use of modern technology and incentives provided by the government have advanced improvement in agriculture.

Impact of Seasonal Low on Sea Level Rise  [PDF]
Mirza Jawwad Baig, M. Jawed Iqbal, Saba Naz
International Journal of Geosciences (IJG) , 2019, DOI: 10.4236/ijg.2019.101003
Abstract: Every region around the globe has its unique climatic conditions which are set based on different orographic constant and atmospheric dynamic features. These features posses’ variability on different time scales. Determining the local sea level change based on terrestrial non-tidal, short-term variability is complicated. Some internal mechanisms of ocean are also taking place along with the external physical ones. We show that variability at Sindh-Baluchistan coastal belt can be greatly explained via dimensional indices of the position and intensity of the atmospheric center of action (COAs). This technique has already proved its usefulness at number of location especially in Northern Atlantic. It takes into account the changes in the atmospheric pressure which is exerted on the sea surface influencing the variability in sea level on seasonal scale and on inter-annual basis. As warming causes thermal expansion of water it also causes changes in atmospheric circulation. Both of these processes affect the sea level variability on their respective time scales. Atmospheric being the quicker one of the two to pass on the effect is also more influential to explain the variability in local sea level. In this attempt the COA approach is used to assess the impact of low pressure on local sea levels.
Why differentiate low molecular weight heparins for venous thromboembolism?
Jawed Fareed, Jeanine M Walenga
Thrombosis Journal , 2007, DOI: 10.1186/1477-9560-5-8
Abstract: 1. Differentiation of low molecular weight heparins from unfractionated heparins2. Differentiation of commercially available low molecular weight heparins, which are produced by different methods.3. Differentiation of the branded low molecular weight heparins from the generic versions of these drugs.4. Differentiation of low molecular weight heparins from synthetic heparin derived oligosaccharides such as the pentasaccharides such as Arixtra and Idraparinux.5. Differentiation of low molecular weight heparins from heparinoids and GAG mixtures such as the danaparoid, dermatan and heparans.6. Differentiation of low molecular weight heparins from synthetic anti-Xa agents.7. Differentiation of low molecular weight heparins from synthetic anti-IIa agents8. Differentiation of low molecular weight heparins from oral anticoagulant drugs such as warfarin.It is now clear that the clinical spectrum of the LMWHs is relatively broader from the different anticoagulant/antithrombotic drugs. Moreover, these agents have multiple interactions with plasmatic and cellular components and produce polytherapeutic effects. The synthetic monotherapeutic agents therefore will not have the same broad clinical profile as the LMWHs. It is important to differentiate the therapeutic effects of individual LMWH as each of these products is approved for specific indications. More recently dalteparin is approved for the treatment of cancer-associated thrombosis, an indication, which is solely approved for this product for this time. Therefore, it is important to differentiate these drugs and caution should be exercised for therapeutic and generic interchange.Of all anticoagulants developed during the past 25 years, LMWHs have become the standard of care for the management of venous thromboembolism. Unlike unfractionated heparin (UFH), different brands of LMWHs can be differentiated biologically and clinically. Based on their different pharmacological and therapeutic profiles, LMWHs are largely conside

Abstract: A simple, accurate liquid chromatography with tandem mass spectrometry (LC/MS-MS) method has been developed and validated in human plasma. The method employed liquid-liquid extraction. Samples containing Mozavaptan were chromatographed on a Intersil ODS-2 column (5μm, 150 x 4.6 mm) at a temperature of 40°C. The isocratic mobile phase composition was a mixture of Methanol / 0.1% formic acid), which was pumped at a flow rate of 1.0 mL / min with split ratio of 90:10.The retention time under these chromatographic conditionswas found to be 1.0 minute with run time 2.6 minute. Diethyl ether was found to be good extracting and produced a satisfactory chromatogram. The developed LC/MS-MS method was found to be selective, simple,sensitive, accurate and linear for the analysis of Mozavaptan in human plasma. The retention time and inturn run time was very short, hence required less mobile phase for the method, making it more economical and rapid.The method was applicable for the pharmacokinetic study of Mozavaptan.
Multiphase Flow Simulations through Tarbela Dam Spillways and Tunnels  [PDF]
Muhammad Abid, Muftooh Ur Rehman Siddiqi
Journal of Water Resource and Protection (JWARP) , 2010, DOI: 10.4236/jwarp.2010.26060
Abstract: Tarbela dam is one of the largest earth filled dam in the world used for power generation and irrigation purposes. Like all reservoirs the sediments inflow in the Tarbela reservoir has resulted in reduction in water storage capacity and is also causing damage to the tunnels, power generating units and ultimately to the plant equipment. This numerical study was performed to predict the flow patterns and characteristics in Tarbela dam. Tunnel 3 and 4 inlets; originally on the bed level were raised in the 3-D model and meshed. Analysis was performed using multiphase flow (water and air) for maximum inflow in the reservoir, i.e., considering summer season and discharging water through different locations, i.e., tunnels and spillways. Pressure, velocities, flow rate and free surface height results obtained were found in good agreement with the analytical and existing results where available. Results show uneven discharge through each gate due to maximum velocity near exits and overall stagnant phenomena of water within the reservoir. Maximum velocity was observed along the spillways outlet. Strong vortex motion was observed near the spillways outlet and tunnel inlets. New design of Tunnel 3 and 4 were suggested to WAPDA in order to decrease the sediment inflow and improvements in design of the spillways were suggested.
