Structural and Morphological Study of a Series of Ball Milled Nanocrystalline Fe1-xAlx (0.3 ≤ x ≤ 0.6) Alloys  [PDF]
Sandeep Rajan, Rajni Shukla, Anil Kumar, Anupam Vyas, Ranjeet Brajpuriya
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.58075
Abstract:

In the present manuscript, the authors have systematically investigated the structural and morphological properties of a series of mechanically alloyed Fe1-xAlx (0.3 ≤ x ≤ 0.6) samples using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). All the samples, after 5 hr of milling, show crystalline structure, irrespective of the constituent concentration and are textured mainly along (110) direction. In Fe-rich samples, the formation of an off-stoichiometric Fe3Al phase is favored and in case of Al-rich samples, both Al-rich phases and clustering of Al atoms are present. Analysis of line breadths was carried out to get an insight into the interrelated effects of average crystallite size, and lattice parameters. The grain size of constituents was decreased to the nanometer range (between 6 - 8 nm) and the constituents dissolved at the nanograin boundaries. Similar conclusions were also revealed from the SEM results which show that the initial shape of particles disappeared completely, and their structure became a mixture of small and large angularshaped crystallites with different sizes. The results of this research could be directly employed in the design of deformation schedules for the industrial processing of Fe-Al alloys.

Imaging in Gluteal Hernia  [PDF]
Chaitra Srinivas, Ajit Kumar Reddy, Anil Kumar Shukla, Himabindhu Pinnammaneni
Open Journal of Medical Imaging (OJMI) , 2016, DOI: 10.4236/ojmi.2016.61002
Abstract: Gluteal hernias are extremely uncommon and occur as a result of deficiency or defect in the gluteal musculature. Our case reports one such incidence in a one year old girl with review of available literature. The clinical presentation and imaging findings are discussed comprehensively. We thus lay emphasis on the importance of real-time ultrasonography as the method of choice to identify hernia contents, peristalsis and obstruction if any.

Punch grafting in vitiligo
Jha Anil,Pandey S,Shukla V
Indian Journal of Dermatology, Venereology and Leprology , 1992,
Abstract: Thirty three patients of 15-35 years age having various types of stable vitilligo from 1-15 years duration were selected for punch grafting. Vitiligo lesions in all these patients were relatively refractory to systemic PUVA therapy tried for a period of 1 to 8 years. The technique of punch grafting was modified from the method described by Falabella and Behl. Complete responses was observed in 10 patients, still under follow up for 1 year and partial response in rest 23 patients who are under observation.
The Synthesis and Characterization of Arc Melted Fe1-xAlx Alloys  [PDF]
Sandeep Rajan, Rajni Shukla, Anil Kumar, Anupam Vyas, Ranjeet Kumar Brajpuriya
Journal of Applied Mathematics and Physics (JAMP) , 2013, DOI: 10.4236/jamp.2013.12002
Abstract:

The paper presents correlation study on a series of Fe1-xAlx alloy samples prepared by arc melting. All the samples show crystalline structure, irrespective of the Al content and are textured mainly along (110) direction. The particle size decreases rapidly with x particularly after x > 0.3. The corresponding magnetic measurements were obtained at room temperature using a VSM, with a maximum applied field of 14 kOe. The results show that the ferromagnetic state of the samples disappears with x, and becomes paramagnetic for alloys with x ≥ 0.4. It is also found that coercivity (Hc) and resistivity increase with x. The results were interpreted in terms of continuous change in their electronic structure i.e. overlap of the electron wave functions of the magnetic atoms with the Al electron wave function.

Radiation Beam Characterization and Dosimetry of Theratron Equinox-80 Telecobalt Machine Using BEAMnrc Monte Carlo Simulation Code  [PDF]
Narayan Prasad Patel, Rahul Shukla, Nagappan Balasubramanian, Rajeev Atri, Anil Kumar Dhull, Hanuman Prasad Yadav, Vivek Kaushal
International Journal of Medical Physics,Clinical Engineering and Radiation Oncology (IJMPCERO) , 2016, DOI: 10.4236/ijmpcero.2016.54030
Abstract: The BEAMnrc code was used for the simulation of the Theratron Equinox-80 telecobalt machine. The phase space of radiation beam was generated at treatment distance of 80 cm for various field sizes. The phase spaces in air were analyzed by BEAMdp data processing program. The electron energy fluence with respect to photon energy was 0.09% and 0.34% for field size of 05 × 05 and 35 × 35 cm2 respectively and it was maximum at the central axis which gradually decreases beyond this. The profiles for photon fluence were in symmetry for all the fields. The full width at half maximum of profiles in photon energy fluence shows good agreement with the field size. The photon energy fluence was flat till the field size of 27 cm2, after which it decreases gradually till the edge in larger field sizes. The air-kerma output factor from the simulation was in good agreement with measured value. We analyzed the dose data scored in the voxels in a large water phantom by simulation using dosxyznrc code. The percentage depth dose for all field sizes was in good agreement with the BJR supplement 25 and the data supplied by the manufacturer of machine. Significant deviation of about 20% in isodose line near the edge of the profile was observed for 35 × 35 cm2 field size. The penumbra widths of all field sizes were comparable except for 35 × 35 cm2, which has a penumbra width of 4.1 cm at 10 cm depth. The significant under dose near the edge as compared to central axis for larger field sizes may be the indication for its careful use in treatment.

Crop Breeding and Applied Biotechnology , 2009,
Abstract: The present study deals with authenticating existing knowledge about 21 Bougainvillea cultivars comprisingof 9 hybrids and their parents through RAPD analysis. The 19 degenerate primer sets generated 234 bands from which 158(67.5%) were polymorphic. The UPGMA based dendrogram divided 21 cultivars into two major groups with Jaccard’ssimilarity coefficient ranging from 0.51 to 0.942. Group A had three cultivars namely Trinidad, Formosa and Dr. H. B. Singhin which Dr. H.B. Singh was confirmed as a hybrid of other two cultivars. Group B was sub divided into 8 clusters. Theparentages of 7 out of 8 hybirds have been confirmed based on clusters. The study concluded that the RAPD technique issuitable for confirmation of parent-hybrid relationship.
AN ANALYSIS OF CRYPTOSYSTEMS USING ELLIPTIC CURVE CRYPTOGRAPHY
Shipra Shukla Dharmendra Lal Gupta Anil Kumar Malviya Sarvottam Dixit
International Journal of Electronics Communication and Computer Engineering , 2011,
Abstract: The true impact of any public-key cryptosystem can only be evaluated in the context of a security protocol. Secure communication is an intrinsic requirement in any transaction. It is very important to implement cryptosystems securely against the attacks. Elliptic Curve Cryptography (ECC) is coming forth as an attractive public key cryptosystem for mobile/wireless environments compared to traditional cryptosystems like RSA and DSA. ECC fits well for an efficient and secure encryption scheme because it provides better security with smaller key sizes, which results in faster computations, lower power consumption, as well as memory and bandwidth savings. However, the digital signature is the indispensable way to ensure the security of web services and has great significance in practical applications. By using a digital signature algorithm we can provide authenticity and validation to the electronic document. ECDSA and ECDH use the concept of ECC. In this article we present ECC and most popular algorithms such as RSA, ECDH, ECDSA and ECPP and a comparative study of all these algorithms have been done
EVALUATION OF NIMBA TAILA AND MANJISTHA CHURNA IN NON HEALING ULCER
Singh Anil Kumar,Srivastava Prabhat Kumar,Shukla Vijay Kumar
International Research Journal of Pharmacy , 2011,
Abstract: This clinical study was done in fifty-one cases of non-healing ulcers of more than six weeks duration to evaluate the efficacy of Nimba taila (Neem oil) externally and Manjistha churna (powder) orally as well as its kwatha externally with an aim to provide an effective management in cases of non healing ulcers. For assessment, wound measurement was done before, during and after treatment and wound healing time as well as lab tests like swab culture, X-ray of affected part, Hemoglobin, Total Leucocytes Count, Differential Leucocytes Count, Liver Function Test, blood sugar level and HbA1c were recorded. Patients with tubercular, malignant ulcers and with ulcers of less than 6 weeks duration were excluded from the study. In the patients treated with only Nimba taila, 31.2% (5/16) patients had 50% healing at eight weeks therapy while with only Manjistha churna, 20.0% (3/15) patients had 50% healing at eight weeks therapy but in the cases, treated with both the drugs, 75.0% (15/20) patients had achieved 50% healing at eight weeks therapy. The study suggests that there is an added effect (quick healing of wound) of Nimba taila with Manjistha churna & its kwatha in cases of non healing diabetic ulcer and single use of Nimba taila or Manjistha churna is not much significant but it is observed keenly that use of Nimba taila alone is comparatively more beneficial than single use of Manjistha churna. It means that both the drugs together are more effective than their separate use.
Effect of soil moisture on growth and arbuscular mycorrhizal colonization of crops and tree seedlings in alfisol
ASHOK SHUKLA*, ANIL KUMAR, ANURADHA JHA and V. D. TRIPATHI
Indian Phytopathology , 2011,
Abstract: A study was conducted to investigate the effect of soil moisture levels (field capacity [FC], half field capacity [HFC] and double field capacity [DFC]) on growth and arbuscular mycorrhizal (AM) colonization of two crops (Phaseolus mungo Roxb. var. PU-35 and Triticum aestivum L. var. WH-147) and seedlings of two multi purpose tree species (Eucalyptus tereticornis Sm. [Clone C-7, ITC, Bhadrachalam] and Albizia procera Benth.). Significant increase in plant growth parameters and phosphorus (P) uptake was recorded after inoculations with AM fungi (Acaulospora scrobiculata Trappe, Glomus cerebriforme McGee and G. intraradix Schenck & Smith). Different AM fungi were effective in terms of plant growth and P uptake at different soil moisture levels with most of them having maximum efficacy at FC. Maximum AM activity in terms of arbuscules, vesicles, sporocarp formation, colonization index and spore count per 100 g soil was also recorded at FC in studied plants. While ranking the importance of two factors studied viz., soil moisture levels and inoculation with AM fungi for their effect on the growth of crop/ trees, inoculations with AM fungi ranked first (explaining 33 to 86% variation in plant growth) for P. mungo, T. aestivum and A. procera (forward selection method), whereas soil moisture levels dominantly explained the growth variation in E. tereticornis, except few cases. The results obtained in present study suggest that inoculation of plants with a suitable AM consortium could be more beneficial as compared to individual AM fungi, depending upon the soil moisture content of the fields and plant species.
