Transformation of Nonlinear Surface Gravity Waves under Shallow-Water Conditions  [PDF]
Iftikhar B. Abbasov
Applied Mathematics (AM) , 2010, DOI: 10.4236/am.2010.14032
Abstract: This article describes transformation of nonlinear surface gravity waves under shallow-water conditions with the aid of the suggested semigraphical method. There are given profiles of surface gravity waves on the crests steepening stages, their leading edges steepening. There are discussed the spectral component influence on the transformation of surface wave profile.
Numerical Simulation of Nonlinear Surface Gravity Waves Transformation under Shallow-Water Conditions  [PDF]
Iftikhar B. Abbasov
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.32021
Abstract: This work considers the problems of numerical simulation of non-linear surface gravity waves transformation under shallow bay conditions. The discrete model is built from non-linear shallow-water equations. Are resulted boundary and initial conditions. The method of splitting into physical processes receives system from three equations. Then we define the approximation order and investigate stability conditions of the discrete model. The sweep method was used to calculate the system of equations. This work presents surface gravity wave profiles for different propagation phases.
Numerical Solution of Blasius Equation through Neural Networks Algorithm  [PDF]
Iftikhar Ahmad, Muhammad Bilal
American Journal of Computational Mathematics (AJCM) , 2014, DOI: 10.4236/ajcm.2014.43019
Abstract:

In this paper mathematical techniques have been used for the solution of Blasius differential equation. The method uses optimized artificial neural networks approximation with Sequential Quadratic Programming algorithm and hybrid AST-INP techniques. Numerical treatment of this problem reported in the literature is based on Shooting and Finite Differences Method, while our mathematical approach is very simple. Numerical testing showed that solutions obtained by using the proposed methods are better in accuracy than those reported in literature. Statistical analysis provided the convergence of the proposed model.

Synthesis, Spectral and Electrochemical Studies of Complex of Uranium(IV) with Pyridine-3-Carboxylic Acid  [PDF]
Misbah Nazir, Iftikhar Imam Naqvi
American Journal of Analytical Chemistry (AJAC) , 2013, DOI: 10.4236/ajac.2013.43018
Abstract:

The investigation of complexation of uranium with biological active ligands is vital for understanding uranium speciation in biosystems. A number of studies have been undertaken for investigating the complexation of uranium in its (VI) oxidation states but similar investigations pertaining to the interaction of uranium, in lower oxidation states, with biological ligands is scarce. The aim of the work is to bridge this gap and studies have been carried out to determine the coordination pattern of pyridine-3-carboxylic acid with uranium(IV). Semi-micro analysis, spectro-analytical techniques, magnetic susceptibility and cyclic voltammetry have been employed for the characterization of the synthesized complex.

Chracterization of the Massive Data Overload of a Hospital Information System– The Autonomous Decentralized Hospital Information System–A Proposal
Iftikhar Ahmed
Asian Journal of Information Technology , 2012,
Abstract: A Hospital Information System (HIS) is designed to manage the information needed by health professionals to perform their jobs effectively and efficiently. Hospital Information Systems that are totally integrated and able to satisfy the information processing requirements of various functional blocks of a hospital are still in infancy. As the progress in ICT (Information and Communications Technology) continues at an ever-increasing pace, new applications of ICT are emerging in the domain of a HIS. These new applications have resulted in a massive data overload for a typical HIS of today. Work is therefore continueing to cope with the requirement in increased throughput and data processing. However these advancements concentrate on improving the existing structure of HIS. A HIS based on the already proven concept of Autonomous Decentralized System is proposed in this study. The proposed structure exhibits the potential to handle the performance requirements of future Information Systems in a Hospital setting in addition to the typical advantages of ADS namely the on-line maintenance, fault tolerance and on-line expansion. A software subsystem installed in each of the distributed computers has an autonomous function for self-management and is capable of coordinating with other subsystems. Each subsystem decides to accept data based on the content code of the message. The ADS concept has already been applied to a number of Information Processing/Control Applications successfully.

BRAIN DEATH CRITERIA
IFTIKHAR HUSSAIN
The Professional Medical Journal , 2009,
Abstract: Snake bite is an important cause of mortality and morbidity. It is estimated that each year snake bite is responsible for 30,000 to 40,000 deaths world wide1. Most snake bites are innocuous and are delivered by non poisonous species. There are 15% of the more than 3000 species of snakes, which are considered dangerous to humans2. The family Viperidae (Pit vipers) is the largest family of venomous snakes. The sub-family Crotalidae (Pit vipers) is also very common in certain parts of the world and includes rattle snakes, cotton mouths (Agkistrodon) and copper heads (Agkistrodon). Elapidae includes the coral snakes. Ophiophagus Hannah (King Cobra) elapidae (kraits and Cobras), Viperidae (Pitless vipers), crotalidae (pit vipers) are indigenous snakes of Pakistan3. Venom is produced by paired glands below the eye. The venom dosage per bite depends on the laps of time since the last bite, and the degree of threat the snake feels.The nostril pits respond to the heat emission of the prey. Venom is most by water and enzymatic proteins like proteases, collagenase and arginine ester hydrolase and hyaluronidase which promotes spread of venom by tissue destruction4. Coral snakes produce potent neurotoxins that later causes respiratory failure from typical systemic neuromuscular blockade. Myonecrosis raises concerns about myogloinuria and renal damage. In clinical practice the snake bite patient either present as haemotoxic or with neurotoxic manifestation. King cobra (Ophiophagus), India cobra (Naja Naja) and brown cobra (Naja Oxiana) produce predominately neurotoxic symptoms. We hereby report a case of cobra snake bite which totally paralyzed the patient for twenty six days. He recovered defying all the clinical brain death criteria5.

STUDY OF FSH, LH AND TESTOSTERONE IN AZOOSPERMIA
IFTIKHAR AHMED
The Professional Medical Journal , 2002,
Abstract: OBJECTIVES: To establish relationship between azoospermia and FSH, LH and testosterone levels. SETTING:Department of Biochemistry, Nishtar Medical College, Multan. PATIENTS AND METHODS: 52 Male azoospermicpatients were studied and their results were compared with 20 age matched healthy controls. RESULTS: Serumconcentration of FSH was found to be significantly raised (P<0.001) in azoospermic patients. LH and testosteroneconcentrations did not show any significant change on comparison with controls. CONCLUSION: It may be concludedthat supplementation of testosterone to the patients of azoospermia will be of no benefit as these patients already had normallevels of this hormone.
NUCLEOLAR ORGANIZER REGIONS IN NORMAL BONE MARROW
Iftikhar Ali
The Professional Medical Journal , 2000,
Abstract: The silver colloid technique for nucleolar organizer regions (AgNORs) was applied to bone marrow smearsin 20 cases of normal morphology marrow. The AgNORs were recorded in the form of ‘clusters’ and ‘dots’.Each developing cell type of myeloid and erythroid series revealed a different pattern of ‘clusters’ and ‘dots’.‘Clusters’ associated with proliferation while mature, non-dividing forms contained only ‘dots’. ‘Clusters’and ‘dots’ have different biologic significance and the method should be adopted while evaluating marrowsmears.
