Genetic Diversity of Pigeonpea (Cajanus cajan (L.) Millsp.) Cultivars and Its Wild Relatives Using Randomly Amplified Polymorphic DNA (RAPD) Markers  [PDF]
Kusum Yadav, Sanjay Kumar Yadav, Anurag Yadav, Veda Prakash Pandey, Upendra Nath Dwivedi
American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.33038
Abstract: Genetic diversity among and between 16 cultivars of pigeonpea (Cajanus cajan (L) Millsp.) and its wild relatives (C. albicans and C. lineatus) analysed using RAPD. Twenty two random primers with an average of 71.2% polymorphism produced 151 polymorphic bands. Cluster analysis based on these 151 RAPD markers revealed relatively low level (0.434 - 0.714) of genetic diversity among cultivars and high level of diversity between cultivars and wild relatives. C. albicans and C. lineatus showed only 0.231 similarity with each other and C. albicans showed relatively higher similarity with C. cajan cultivars than that showed by C. lineatus. In dendrogram the 16 cultivars grouped into two distinct clusters comprising of seven and nine genotypes each while the wild species form out groups. Bootstrap analysis of the dendrogram was performed and resulted in significant bootstrap values. Principal components analysis (PCA) also revealed the similar results that of unweighted pair group method with arithmetic mean (UPGMA). The first, second and third PCs contributed 55.9%, 5.9%, and 5.6% of the variation, respectively, with cumulative variation of the first three PCs was 67.4%.

Genetic relationships of 16 cultivars of pigeonpea (Cajanus cajan (L) Millsp.) and its two wild relatives (C. albicans and C. lineatus) from different parts of the India were analysed using 22 random amplified polymorphic DNAs (RAPDs) primers and 10 inter simple sequence repeats (ISSRs) primers. Twenty two RAPD primers yielded 151 polymorphic markers (71.2%) with an average of 6.8 polymorphic band/primer. Cluster analysis based on these 151 RAPD markers revealed relatively low level (0.434 - 0.714) of genetic diversity among cultivars and high level of diversity between cultivars and wild relatives. Ten ISSR primers produced 100 bands across 16 cultivars and its wild relatives out of which 93 (93%) were polymorphic with an average of 9.3 polymorphic band/primer. Cluster analysis based on these 93 ISSR markers also revealed relatively higher level (0.328 - 0.827) of genetic diversity among cultivars as compared to RAPD markers. The polymorphic markers obtained by both RAPD and ISSR primers were pooled and the genetic diversity analysis based on these 244 markers was analysed. Jaccard’s similarity coefficient obtained by pooled data revealed very narrow range (0.477 - 0.720) among cultivated and high range between cultivated and wild species C. albicans (0.240 - 0.331) and C. lineatus (0.163 - 0.193). In the UPGMA based dendrogram the 16 cultivars were grouped into three distinct clusters. Cluster I contained two genotypes, cluster II had six and cluster III had eight genotypes. Principal components analysis (PCA) also resulted in similar pattern as that of UPGMA based analysis. The first three PCs contributed 56.26%, 5.71% and 4.97% of variation, respectively, with cumulative variation of the first three PCs was 66.96%. Both the markers and the combined data revealed similar pattern with narrow diversity among cultivars and higher diversity between cultivars and wild one, but

Analysis of Simple Sequence Repeats Information from Floral Expressed Sequence Tags Resources of Papaya (Carica papaya L.)  [PDF]
Priyanka Priyanka, Dileep Kumar, Anurag Yadav, Kusum Yadav, U. N. Dwivedi
American Journal of Plant Sciences (AJPS) , 2017, DOI: 10.4236/ajps.2017.89155
Abstract: Papaya (Carica papaya L.) is one of the most economically, medicinally and nutritionally important tropical fruit crops. Expressed sequence tags (ESTs) derived simple sequence repeat (SSR) markers are more valuable as they are derived from conserved genic portion. Development of EST-SSRs markers through in silico approach is cheaper, less time consuming and labour-intensive. In this study, we aimed to mine SSRs and developed EST-SSR primers from papaya floral ESTs. A total of 75,846 papaya floral ESTs were downloaded from public database National Centre for Biotechnology Information (NCBI). A total of 26,039 floral unigenes (7961 contigs and 18,078 singletons) were generated after assembly of these ESTs. From these floral unigenes, 433,782 perfect SSRs, 204,968 compound SSRs and 6061 imperfect SSRs were mined, respectively.
on Privacy Using User Anonymity And Dummy Locations
Kusum Gupta, Ajay Singh Yadav and Shashank Yadav
International Journal of Innovative Technology and Creative Engineering , 2011,
Abstract: This paper concentrates on location privacy, a particular type of information privacy that can be defined as the ability to prevent others from learning one’s current or past location. Here we are proposing a new technique that uses user anonymity and dummy locations for location privacy while using location aware application server. User communicates with the server through a trusted proxy server. It sends dummy locations to the application server with its original position. The user uses temporary pseudonyms that are changed frequently according to some algorithm. Whenever pseudonyms are changed by a user, dummy locations are chosen in a tricky fashion. That makes the task of tracing the user very difficult.
Affect of Globalization on Multinational Enterprises

International Journal on Research and Development : A Management Review , 2013,
Abstract: Globalization has made the world very small. We have to cast human beings a tune with newer requirements for which they require knowledge. Knowledge is based in experience, faith; common sense & interest for particular point of view change in selection recruitment program, induction program, Training and Development policies are needed to be made. The roles and responsibilities of Human Resources departments are transforming as the modern business faces pressures of globalization. The global supply of talent is short of its long-term demand, and the gap is a challenge for employers everywhere. The shortage between the demand and supply of talent is likely to continue to increase, notably for high skilled workers and for the next generation of business executives. Now organizations need to place greater emphasis on attracting human capital rather than financial capital. Global staffing and management of a workforce diverse in culture and language skills and dispersed in different nations are the key goals of global human resources. Only those multinational enterprises willing to adapt their human resource practices to the changing global labor market conditions will be able to attract and retain high performing employees. Companies with the ability to foresee their business needs and their workforce needs – especially for high skills – will gain the decisive competitive advantage. Globalization can therefore be said to have had a phenomenal impact on a developing economy

Madhu Jain, Kusum Lata, Shivi Jain
Open Journal of Obstetrics and Gynecology (OJOG) , 2011, DOI: 10.4236/ojog.2011.13022
Abstract: Torsion of the ovary is an uncommon condition. It is the 5th most common gynaecological emergency. It most commonly occur in reproductive age group, on right side, often in presence of congenital abnormalities of adnexa but may occur in their absence too. Adnexal torsion often poses a diagnostic challenge because of non specific symptoms of presentation. Ultrasound with colour Doppler may be helpful.
Wide Range RH Detection with Digital Readout: Niche Superiority in Terms of Its Exceptional Performance and Inexpensive Technology  [PDF]
Manju Pandey, Kusum Sharma, Saikh Safiul Islam
Advances in Materials Physics and Chemistry (AMPC) , 2019, DOI: 10.4236/ampc.2019.92002
In this paper we report alumina based capacitive humidity sensor having exceptional sensing performance in wide range RH segment (10% - 90%). The developed sensor has an improvement of accuracy, reliability, and economic efficiency; apart from fast response and recovery time (~s), negligible baseline drift and high selectivity for moisture. The sensing mechanism was discussed based on their microstructures, such as surface area and mesopore volume. In general, at low humidity, surface area and water adsorption play the dominant role, while at high humidity, mesopore volume and capillary condensation become important. Standard characterization techniques such as AFM, FESEM, BET, XRD and impedance spectroscopy were employed for micro-structural and electrical characterization of RH sensor. The nano porous alumina film undergoes a huge change in dielectric upon adsorption of moisture, ensuing large change in capacitance. Additionally, a prototype RH meter has been developed with digital readout for humidity. The interface circuit was based on capacitor-to-duty cycle (CDC) converter. The proposed digital circuit has the advantage of performing adaptive measurements as a function of resolution and bandwidth. The prototype instrument can be used for sub ppm level moisture detection where stability and response are completely unaffected even in highly toxic ambience viz. 4% ammonia and 4% chlorine.
Optimising biocatalyst design for obtaining high transesterification activity by α-chymotrypsin in non-aqueous media
Kusum Solanki, Munishwar Gupta
Chemistry Central Journal , 2008, DOI: 10.1186/1752-153x-2-2
Abstract: It was found that EPRPs of α-chymotrypsin prepared by precipitation with n-propanol in the presence of trehalose contained substantial amount of trehalose (even though trehalose alone at these lower concentrations was not precipitated by n-propanol). The presence of trehalose in these EPRPs resulted in much higher transesterification rates (45.2 nmoles mg-1min-1) as compared with EPRPs prepared in the absence of trehalose (16.6 nmoles mg-1min-1) in octane. Both kinds of EPRPs gave similar initial transesterification rates in acetonitrile. Use of higher concentrations of trehalose (when trehalose alone also precipitates out), resulted in the formation of PCMCs, which showed higher transesterification rates in both octane and acetonitrile. SEM analysis showed the relative sizes of various preparations. Presence of trehalose resulted in EPRPs of smaller sizes.The two different forms of enzymes (EPRP and PCMC) known to show higher activity in organic solvents were found to be different only in the way the low molecular weight additive was present along with the protein. Therefore, the enhancement in the transesterification activity in EPRPs prepared in the presence of trehalose was due to: (a) better retention of essential water layer for catalysis due to the presence of the sugar. This effect disappeared where the reaction media was polar as the polar solvent (acetonitrile) is more effective in stripping off the water from the enzyme; (b) reduction in particle size as revealed by SEM. In the case of PCMC, the enhancement in the initial rates was due to an increase in the surface area of the biocatalyst since protein is coated over the core material (trehalose or salt).It is hoped that the insight gained in this work would help in a better understanding for designing high activity biocatalyst preparation of non-aqueous media.The possibility of using enzymes in low water containing organic solvents has expanded their applications in organic synthesis [1-4]. In many cases
Golden Research Thoughts , 2013, DOI: 10.9780/22315063
Abstract: The aim of this paper is to encourage and assist individuals and institutions which work to promote and protect human rights to engage with corruption issues and collaborate more closely with anti-corruption organizations. It may also assist those who combat corruption to recognize the value of human rights to their work and the advantages of closer collaboration with human rights organizations. The paper may help to raise awareness among key stakeholders and the public of the links between corruption and human rights, thereby diminishing public tolerance of corruption and strengthening public support for anticorruption measures. The paper already set itself a demanding objective when it sought to clarify the formal links between violations of rights and acts of corruption by state officials. Extending the analysis to cover the subject of private corruption would have made the work extremely complicated to complete. This is therefore not a scholarly treatise but a paper written mainly for human rights specialists and organizations who want to know how they might effectively address corruption and the harm it causes.
International Journal of Innovative Research in Computer and Communication Engineering , 2013,
Abstract: Image fusion is processes of combining complementary information from a set of input images. The resultant fused image give large and reliable information. In this paper we study about Discrete wavelet and Discrete Multiwavelet and there use in image fusion. Discrete wavelet transform (DWT) technique is used for multi Resolution fusion. Multi Resolution fusion uses wavelet transform at multi scale for the representation of the source images. Multiwavelets are extension of scalar wavelets, and have many advantages over scalar wavelets. Multiwavelet analysis can provide a more absolute image analysis than wavelet multiresolution analysis.In this paper DWT and DMWT are qualitatively compaired with each other.
