Promoting Nuclear Security Education and Training Activities at Amity University, India

In the present era of global nuclear governance, it is the responsibility of every individual not only the security personals to be accountable for the security of nuclear materials, facilities and radioactive materials. Amity university and other universities of India are the largest educational networks for young professionals who will enter the nuclear programme in India and will be involved in the management of nuclear and other radioactive materials in a wide variety of applications such as hospitals, industrial applications and nuclear facilities. Amity University Uttar Pradesh is taking leading part to sensitize the importance of nuclear security amongst the students and faculty members of various Indian institutions and research organization. Amity University is also motivating women academicians to take lead in nuclear security. This paper describes details of various events organized in India with the initiative of INSEN, IAEA; Texas A&M University, USA and WINS Academy, Vienna, Austria

Women in Nuclear Science & Technology in India: Challenges & Opportunities

Women have been actively contributing toward frontline research and development of various advanced technologies in the nuclear domain and playing a crucial role in key positions. However, proportional representation of women in various decision-making positions at higher levels in politics, diplomacy, military affairs, science, and technology remains low, and most of these positions remain male-dominated. We see that women often find it difficult to achieve leadership roles for several reasons, but often from an implicit bias in society. The stereotypical image of women in society is still propagated very discreetly. In recent times, Indian women have made big strides in several frontline sectors like Information Technology (IT), Biotechnology, and on corporate levels. More recently, organizations, including the Indian government, have been promoting an awareness of gender equality in various fields including nuclear technology. Amity University has also been motivating women academicians to take a lead in various fields including nuclear technology and nuclear security. This paper describes various initiatives that the Government of India has taken, along with many Indian organizations, including Amity University, to promote women in various fields especially in nuclear technology. This paper also discusses the opportunities for Indian women, their contributions, and challenges

POINT OF FACIAL NERVE VULNERABILITY DURING MASTOIDECTOMY AMONG INDIAN PATIENTS: A CROSS-SECTIONAL STUDY.

Background The petrous part of the temporal bone houses the major part of the intracranial courses of the facial nerve. The nerve might be injured during surgery involving the mastoid and tympanic region. The damage may cause facial asymmetry and impairment of facial muscle function. It may ruin a patient's face, affecting their mental and social health. This research seeks to identify the anatomical site most susceptible to facial nerve injury during surgical treatment of the mastoid and tympanic cavity.  Methods A cross-sectional study of 198 mastoidectomies conducted by 10 surgeons was done. The number of mastoidectomies by each surgeon, the location of the injury, the grade of the nerve injury, and the number of recoveries were recorded. Statistical analysis was performed on the data obtained.  Results Nine facial nerve injuries were reported among the 198 cases analyzed. The second genu was the most vulnerable site of nerve injury in our study. A Grade 3 injury was mostly found in the case of mastoidectomies. More than 70% of the cases recovered from the ‘facial nerve’ injury.  Conclusion Injury of the nerve during mastoidectomy is the major complication faced by an otolaryngologist. Also, the injury paralyzes the facial muscles, having a significant impact on the patient’s life. The injury can be best avoided by a thorough study of the anatomy of the nerve. In our study, it is found that the second genu is the prominent site of the injury. The otolaryngologist should be careful while performing the mastoidectomies and monitor the facial nerve simultaneously.  Recommendations Future research should focus on developing targeted surgical training and incorporating intraoperative nerve monitoring to reduce facial nerve injuries during mastoidectomies, thereby improving patient outcomes

Synthesis of homochiral bis (oxazolinyl) pyridine type ligands for asymmetric cyclopropanation reactions

Homochiral bis(oxazolinyl)pyridine type ligands were synthesized from (S)-valine and converted into their Cu(II) complexes. Reduction of these Cu(II) complexes into Cu(I) with diazoesters was studied by uv-vis and epr spectroscopy. The enantioselective cyclopropanation reaction was carried out using styrene as a model substrate. The Cu(II) complexes of the type 5 were synthesized for cyclopropanation reaction. The reduction of Cu(II) into Cu(I) with diazoesters was studied by uv-vis and epr spectroscopy

Synthesis of versatile intermediates for cyclopentanoid natural products via enantioselective deprotonation of substituted cyclopentene oxide

Enantioselective deprotonation of cis and trans-3,4-epoxycyclopentan-1-ol derivatives with phenylglycine based ligand (R)-5 was studied. The cyclopentanoid intermediates were obtained in a maximum of 88% ee

Quantification of minor, trace and toxic elements in stems of Santalum album (L.), Mangiferra indica (L.) and Tinospora cordifolia by instrumental neutron activation analysis

Stems of Santalum album (Sandalwood), Mangiferra indica (Mango wood), and Tinospora cordifolia (Giloy) are widely used in the preparation of herbal medicines and formulations in the traditional Indian health care system called Ayurveda. These were analyzed for 4 minor (K, Ca, Cl, Mg) and 13 traces (As, Ce, Co, Cr, Cu, Fe, Hg, La, Mn, Na, Se, V, and Zn) including toxic elements by instrumental neutron activation analysis (INAA). Samples in powder form along with reference materials (NIST SRM 1547 and INCT MPH-2) as comparators were irradiated for 1 min/6 h in Dhruva/CIRUS reactors at BARC, Mumbai. Gamma activity was measured by high-resolution gamma-ray spectrometry. In general, K, Ca, Fe, Mn, and Zn contents are very high in all the samples but Santalum album, widely used as a perfume, is more enriched in K, Ca, Cr, Zn, and Se. The concentration of Ca is always high as a major constituent (> 10 mg/g) in all the stem/bark of plant species. A strong inverse correlation (R2 = 0.9999) was observed between Fe and Zn in all three samples and that may be useful in drug manufacturing

Bio Inspired Modified Internal Model Control Approach for Improved Disturbance Rejection of Piezo Micro Manipulator

Classical Internal Model Control based approach for controller design has been used in different industrial control applications as it allows good set point tracking performance, especially for processes neglecting time delay. However, in many process control applications including nonlinear piezo electric actuation (PZA), disturbance rejection plays an important role compared to set point tracking. The present research firstly proposes an optimal filter design in series with a Modified Internal Model Control (M-IMC) based Proportional -Integral-Derivative (PID) controller for better set point tracking, improved disturbance rejection with reduced controller hardware resource requirement compared to classical IMC. Two efficient swarm intelligence based evolutionary soft computational techniques viz. Particle Swarm Optimization (PSO) and Bacterial Foraging Optimization (BFO) are then exploited towards optimizing a control evaluation index based fitness function to design the M-IMC control parameters, including filter time constant. The distillation of bio inspired principles in control is seen to exhibit exciting results when the optimized parameters are utilized in the piezo plant modeled using a Dahl based second order system. The performance of the controller has been evaluated by subjecting the plant to several perturbations as well as to external disturbances. The results illustrate the efficiency of the PSO based M-IMC over other controllers
