Antifungal Potential of Transition Metal Hexacyanoferrates against Fungal Diseases of Mushroom  [PDF]
Charu Arora Chugh, Dipti Bharti
Open Journal of Synthesis Theory and Applications (OJSTA) , 2012, DOI: 10.4236/ojsta.2012.13005
Abstract: Ferrocyanides of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) were synthesized and characterized by IR spectra, magnetic susceptibility, thermal gravimetric analysis, elemental analysis and X ray diffraction studies. Antimicrobial potential of these complexes have been evaluated. Antifungal screening of these complexes has been carried out against Mycogone perniciosa and Verticillium fungicola causing wet and dry bubble diseases of button mushroom respectively. Nickel ferrocyanide has been found to be most effective against Mycogone perniciosa with 60% inhibitory effect while cadmium ferrocyanide has exhibited significant potential of 85% against Verticillium fungicola.
On the Rate of Convergence of Some New Modified Iterative Schemes  [PDF]
Renu Chugh, Sanjay Kumar
American Journal of Computational Mathematics (AJCM) , 2013, DOI: 10.4236/ajcm.2013.34037
Abstract:

In this article, following Bizare and Amriteimoori [1] and B. Parsad and R. Sahni [2], we modify Ishikawa, Agarwal et al., Noor, SP iterative schemes and compare the rate of convergence of Ishikawa, Agarwal et al., Noor, SP and new modified Ishikawa, Agarwal et al., Noor, SP iterative schemes not only for particular fixed value of an,bn,rn but also for varying the value of an,bn,rn. With the help of two numerical examples, we compare the converging step.

Banach Λ-Frames for Operator Spaces  [PDF]
Mukesh Singh, Renu Chugh
Advances in Pure Mathematics (APM) , 2014, DOI: 10.4236/apm.2014.48048
Abstract:

The Banach frame for a Banach space X can reconstruct each vector in X by the pre-frame operator or the reconstruction operator. The Banach Λ-frame for operator spaces was introduced by Kaushik, Vashisht and Khattar [Reconstruction Property and Frames in Banach Spaces, Palestine Journal of Mathematics, 3(1), 2014, 11-26]. In this paper we give necessary and sufficient conditions for the existence of the Banach Λ-frames. A Paley-Wiener type stability theorem for Λ-Banach frames is discussed.

Cloning of gag gene of HIV-1 subtype c (Indian strain) into a mammalian expression vector and in vitro expression studies
Chugh P
Indian Journal of Medical Microbiology , 2003,
Abstract: PURPOSE: Acquired immunodeficiency syndrome caused by HIV-1 is one of the biggest health problems we are facing today. It is required to concentrate efforts towards designing a safe, effective and affordable vaccine candidate in the context of the growing epidemic worldwide. Recently the approach of DNA based immunogen has evoked a lot of enthusiasm in the preclinical models. METHODS: This study was designed towards a subtype C based gag DNA construct in the expression vector pJW4304. The gag and protease genes of HIV-1 subtype C were cloned into a mammalian expression vector pJW4304. The cloning strategy was designed so as to express a naturally processed form of the protein. Expression of gag protein by the construct pJWgagprotease49587 was evaluated by western blotting, p24 antigen capture ELISA and electron microscopy. RESULTS: Gag p24 was detected both in the supernatant and in the transfected cells. Extra cellular p24 protein was estimated by p24 antigen capture ELISA. Immunoblotting using HIV positive polyclonal sera further confirmed the expression and processing of gag gene. The 24kDa band has been observed in cell lysates, which indicates that the proper processing is taking place in the presence of protease. Virus like particles were seen budding from the cell membrane 24 and 48 hours post transfection by transmission electron microscopy. CONCLUSIONS: The recombinant construct pJWgagprotease49587 has shown good expression in vitro and therefore is a good candidate to study immunogenicity of the construct. Immunogenicity testing in mice is being carried out currently with this construct.

Prodirect Manipulation: Bidirectional Programming for the Masses
Ravi Chugh
Computer Science , 2015,
Abstract: Software interfaces today generally fall at either end of a spectrum. On one end are programmable systems, which allow expert users (i.e. programmers) to write software artifacts that describe complex abstractions but are disconnected from their eventual output. On the other end are domain-specific graphical user interfaces (GUIs), which allow end users (i.e. non-programmers) to easily create varied content but present insurmountable walls when a desired feature is not built-in. Both programmatic and direct manipulation have distinct strengths, but users must typically choose one over the other or use some ad-hoc combination of systems. Our goal, put simply, is to bridge this divide. We envision novel software systems that tightly couple programmatic and direct manipulation --- a combination we dub prodirect manipulation --- for a variety of use cases. This will require advances in a broad range of software engineering disciplines, from program analysis and program synthesis technology to user interface design and evaluation. In this extended abstract, we propose two general strategies --- real-time program synthesis and domain-specific synthesis of general-purpose programs --- that may prove fruitful for overcoming the technical challenges. We also discuss metrics that will be important in evaluating the usability and utility of prodirect manipulation systems.

Efficacy of Slow Reversal Hold and Isometrics in Improving Muscle Strength, Increasing Range of Motion, and Reducing Pain in Patients with Osteoarthritis of Knee  [PDF]

Abstract: Osteoarthritis of knee is a common problem in the elderly population worldwide. Physical therapy has been shown to be useful in decreasing pain and increasing mobility in this population. The aim of this study was to study the effectiveness of slow reversal hold and isometric exercise techniques in reducing pain, increasing muscle strength, and increasing range of motion for knee flexion in patients with osteoarthritis of knee. The other aim of this study was to compare the relative effectiveness of these two interventions. 60 subjects participated in this study and were randomly assigned either to the slow reversal hold group (n = 30) or, to the isometrics exercise group (n = 30). All subjects performed their respective exercises for 3 weeks. Pain scores using the visual analog scale, muscle strength using manual muscle testing of quadriceps and hamstrings, and range of motion (ROM) for knee flexion using a goniometer were recorded both pre-treatment and post-treatment for both left and right knees. Both the interventions showed a significant decrease in pain scores, an increase in muscle strength, as well as an increase in the ROM. However, ROM was significantly increased in the slow reversal hold group as compared to the isometrics group in both knees. It was concluded that both exercise techniques could be useful in patients with osteoarthritis of knee for decreasing pain and increasing muscle strength. Slow reversal hold technique might be a better technique than isometrics for increasing ROM for knee flexion.
Strong Convergence of a New Three Step Iterative Scheme in Banach Spaces  [PDF]
Renu Chugh, Vivek Kumar, Sanjay Kumar
American Journal of Computational Mathematics (AJCM) , 2012, DOI: 10.4236/ajcm.2012.24048
Abstract:

In this paper, we suggest a new type of three step iterative scheme called the CR iterative scheme and study the strong convergence of this iterative scheme for a certain class of quasi-contractive operators in Banach spaces. We show that for the aforementioned class of operators, the CR iterative scheme is equivalent to and faster than Picard, Mann, Ishikawa, Agarwal et al., Noor and SP iterative schemes. Moreover, we also present various numerical examples using computer programming in C++ for the CR iterative scheme to compare it with the other above mentioned iterative schemes. Our results show that as far as the rate of convergence is concerned 1) for increasing functions the CR iterative scheme is best, while for decreasing functions the SP iterative scheme is best; 2) CR iterative scheme is best for a certain class of quasi-contractive operators.
