Molecular Basis of Aluminium Toxicity in Plants: A Review  [PDF]
Nidhi Gupta, Shailendra Singh Gaurav, Ashwani Kumar
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.412A3004
Abstract:

Aluminium toxicity in acid soils having pH below 5.5, affects the production of staple food crops, vegetables and cash crops worldwide. About 50% of the world’s potentially arable lands are acidic. It is trivalent cationic form i.e. Al3+ that limits the plant’s growth. Absorbed Aluminium inhibits root elongation and adversely affects plant growth. Recently researches have been conducted to understand the mechanism of Aluminium toxicity and resistance which is important for stable food production in future. Aluminium resistance depends on the ability of the plant to tolerate Aluminium in symplast or to exclude it to soil. Physiological and molecular basis of Aluminium toxicity and resistance mechanism are important to understand for developing genetically engineered plants for Al toxicity resistance. This paper provides an overview of the state of art in this field.

Extent of Awareness and Food Adulteration Detection in Selected Food Items Purchased by Home Makers
Nidhi Gupta,Priti Panchal
Pakistan Journal of Nutrition , 2009,
Abstract: Food is essential for sustenance of life. Adulteration of food cheats the consumer and can pose serious risk to health in some cases. The present study was planned with the main objective of identifying buying practices of homemakers and their extent of awareness related to selected food products. Stratified sampling method with questionnaire cum interview schedule was adopted to collect data. Tool was standardized by difficulty index, validity index and split half reliability method. Statistical test such as chi-square between awareness and occupation, t-test among age group, educational level and extent of awareness were carried out. Study revealed that respondent’s awareness related to rights and responsibilities was good but poor related to food adulteration. Education, family income and occupation had an effect on extent of awareness. Age and awareness has no correlation while a positive correlation was found between family income and awareness. This research paper is the part of the work carried out under the project funded by University Grant Commission, India.
A Novel Architecture for Domain Specific Parallel Crawler
Nidhi Tyagi,Deepti Gupta
Indian Journal of Computer Science and Engineering , 2010,
Abstract: The World Wide Web is an interlinked collection of billions of documents formatted using HTML. Due to the growing and dynamic nature of the web, it has become a challenge to traverse all URLs in the web documents and handle these URLs, so it has become imperative to parallelize a crawling process. The crawler process is further being parallelized in the form ecology of crawler workers that parallely download information from the web. This paper proposes a novel architecture of parallel crawler, which is based on domain specific crawling, makes crawling task more effective, scalable and load-sharing among the different crawlers which parallel download web pages related to different domains specific URLs.

AN INVESTIGATION OF TOOL CONDITION MONITORING
Dr. Pratesh Jayaswal,Nidhi Gupta
International Journal of Engineering Science and Technology , 2012,
Abstract: In any manufacturing industry, machine tools play an important role in the production of parts. The dimensional accuracy and surface finish of the work piece depends mainly on the condition of the machine. The vibration signatures for different arrangement are recorded to determine the dynamic characteristics of the system, whichinclude work piece, tool and lathe components. These vibration signatures are analyzed to determine causes of inaccuracy in the manufacturing process and faulty components. Many condition monitoring techniques are available to monitor the machine tool experimentally. Among these techniques vibration monitoring is the most widely used technique because most of the failures in the machine tool could be due to increased vibration level. Experimental vibration analyses are conducted for a lathe system to detect the possibility of faults and to develop accurate cutting process. Experiments are carried out using the condition monitoring instrumentVIBROMETER to measure vibration severity for different cutting speed, depth of cut, feed rate. The value of vibration (rms and peak) at tool post and at bearing is determined from the experimental analyses, it is found that the vibration velocity increases at the cutting speed, depth of cut and feed rate increases.
A Novel Security Approach in Mobile Agent Using Encryption
Nidhi Gupta,Dr. Anurag Dixit
International Journal of Computer Science and Management Studies , 2012,
Abstract: The appearance of software agents has given rise too much discussion of what such an agent is and how it differs from programs in general. An agent is anything that can be viewed as perceiving its environment through sensors & acting upon that environment through actuators. The existing systems can be classified in the context of singleagent systems and multi-agent systems. Mobile agents cantransport themselves from one host to another. Mobile agents have been developed as an extension to and replacement of the client-server model. The proposed system is Mobile Agent System. It reduces network load and latency in which there is usually no transmission ofintermediate result. This conserves the network bandwidth .Since the agents are autonomous; the mobile device that dispatches the agent need not be connected all the time.

Micronuclei: An essential biomarker in oral exfoliated cells for grading of oral squamous cell carcinoma
Jadhav Kiran,Gupta Nidhi,Ahmed Mujib B
Journal of Cytology , 2011,
Abstract: Background : Micronuclei in exfoliated oral epithelial cells have been shown in some studies to correlate with severity of this genotoxic damage. This severity can be measured in terms of grading of the lesions. Aim : To correlate frequency of micronuclei (MN) in oral exfoliated cells in clinically diagnosed cases of oral squamous cell carcinoma (OSCC) followed by a histopathological grading. Materials and Methods : The study subjects consisted of clinically diagnosed cases of OSCC. Healthy subjects without any tobacco consumption habits formed the control group. The cytosmears from both groups were stained with rapid Papanicolaou stain. MN were identified according to the criteria given by Countryman and Heddle with some modifications. Results : The frequency of MN was three to four times higher in patients with OSCC as compared to patients in the control group and the difference was found to be highly significant. In 75% cases, the cytological grade as determined by the frequency of micronuclei correlated with the histopathological grade and this observation was statistically significant. Conclusions : MN can be a candidate to serve as a biomarker for prediction of the grade of OSCC.
Immunomodulation by Hibiscus rosa-sinensis: Effect on the Humoral and Cellular Immune Response of Mus Musculus
Nidhi Mishra,Vijay Lakshmi Tandon,Rekha Gupta
Pakistan Journal of Biological Sciences , 2012,
Abstract: In West India, the Hibiscus rosa-sinensis L. (Malvaceae) is traditionally used as tea as a natural diuretic. Extract of this plant contains Vitamin C and is used traditionally as a mild medicine. In spite of a long history of traditional medicinal value of H. rosa-sinensis still no data are available for immunomodulatory activity. In present investigation, aqueous extract of H. rosa-sinensis (AEHrs) (500 mg kg-1 BW) was intraperitoneally (IP) injected to the male Swiss albino mice (Mus musculus) to evaluate the immunomodulatory property of extract. In addition for evaluation of phytochemical constituents of flowers of H. rosa-sinensis HPTLC was performed. The crude extract of H. rosa-sinensis has immunomodulatory activity. After the 15 days treatment, the number of plaque forming cells increased by 0.6%, antibody titre was increased 38.15% and significant increase of 52% was observed in DTH response. At the same concentration of dose the level of serum IL-1α enhanced significantly (14.27%) whereas a considerable decrease (32.70%) in the concentration of IL-2 was observed among AEHrs treated mice in comparison to the control mice. HPTLC chromatogram revealed that H. rosa-sinensis posses alkaloid (Rf 0.93) and flavonoids (Rf 0.02, 0.06, 0.14) on the basis of Rf values. Results of investigation supports for the immunomodulatory activity of H. rosa-sinensis aqueous extract.
