Anisotropy of the Stone-Wales Defect and Warping of Graphene Nano-ribbons: A First-principles Analysis

Stone-Wales (SW) defects, analogous to dislocations in crystals, play an important role in mechanical behavior of $sp^2$-bonded carbon based materials. Here, we show using first-principles calculations that a marked anisotropy in the interaction among the SW defects has interesting consequences when such defects are present near the edges of a graphene nano-ribbon: depending on their orientation with respect to edge, they result in compressive or tensile stress, and the former is responsible to depression or warping of the graphene nano-ribbon. Such warping results in delocalization of electrons in the defect states.Comment: 8 page

Diffusive phase transitions in ferroelectrics and antiferroelectrics

In this paper, we present a microscopic model for heterogeneous ferroelectric and an order parameter for relaxor phase. We write a Landau theory based on this model and its application to ferroelectric PbFe$_{1/2}$Ta$_{1/2}$O$_3$ (PFT) and antiferroelectric NaNbO$_3$:Gd. We later discuss the coupling between soft mode and domain walls, soft mode and quasi-local vibration and resulting susceptibility function.Comment: 6 pages, Fundamental physics of ferroelectrics 200

AYURVEDIC MANAGEMENT OF SEVERE AMAVATA (RHEUMATOID ARTHRITIS) WITH ITS COMPLICATIONS: A CASE STUDY

Amavata is one of the crippling diseases. It is the systemic disorder in which pathogenic constituents are mainly Aama and Vata. The symptoms of Amavata are identical to Rheumatoid arthritis and Rheumatic fever. According to Ayurveda, Amavata is the disease which is mentioned under the category of Vata- Kaphaja vyadhi. Research has proven that Ayurvedic treatment is effective in the management of Amavata. Present case study was done on the female patient of Amavata, we found that Ayurvedic medicines improve Jatharagni and leads to the formation of other Dhatu as well as stop the formation Aam. In this study, patient is having many complaints such as joint pain, joint stiffness, cough, breathlessness, hoarseness of voice etc. Patient was given Ayurvedic medicines such as Suvarnabhasma, Sihnad Guggul, Amavatari Rasa and some Pancharkarma therapy such as Hrudyabasti, Nasya. Patient was feeling much better than earlier and she felt that about 95% of her symptoms got decreased. From the modern aspect, the non-steroidal anti-inflammatory drugs (NSAID`S) and disease modifying anti-rheumatic drugs (DMARD`S) are the main stay in this condition, however they have serious adverse effects and have limitations for long term therapy. Continuous use of allopathic drugs leads to symptoms like constipation, nausea, abdominal discomfort. So we stopped the allopathic medicine and started above mentioned Ayurvedic medicine and Panchakarma treatment and gradually alleviated above symptoms

Drug utilisation study in surgery outpatient department at Ashwini Rural Medical College, Kumbhari, Solapur

Background: Drug utilization studies should be regularly conducted to increase therapeutic efficacy, decrease adverse effects and provide feedback to prescribers to promote the rational use of drugs. Systematic audit of prescriptions in Surgery Outpatient Department are very few in India. This study was conducted to study drug prescription pattern in Surgery Outpatient Department (OPD) in Ashwini Rural Medical College, Kumbhari.Methods: Six hundred prescriptions were screened and analyzed as per the study parameters at Surgery OPD of Ashwini Rural Medical College, Kumbhari. Study parameters like demographic profile of the patient like age, sex and diagnosis were recorded. Also groups of drugs commonly prescribed, number of drugs per patient, drug profile and drawbacks of prescription if any were recorded and analyzed. The percentage of the drugs prescribed by generic names and from the essential drug list was calculated.Results: Most common group of drugs prescribed by physicians were drugs for peptic ulcer (27.26%), followed by antimicrobials (20.89%). The average number of drugs prescribed per patient was 2.98. Drug prescription by generic name was low (8.82%). The incidence of polypharmacy was common occurrence and some prescriptions had small drawbacks like absence of diagnosis, absence of doctor’s signature, absence of patient age etc.Conclusions: Prescribing by generic name and from the essential drug lists should be encouraged. Training sessions on the correct method of writing prescriptions are needed

Drug utilisation study in medicine outpatient department at Ashwini Rural Medical College, Kumbhari, Solapur, India

Background: Drug utilization studies are used to analyze different aspects of the use of drugs and to implement methods of improving therapeutic quality. This study was conducted to study drug prescription pattern in Medicine Outpatient Department (OPD) in Ashwini Rural Medical College, Kumbhari. Methods: Six hundred prescriptions were screened & analyzed as per the study parameters at Medicine OPD of Ashwini Rural Medical College, Kumbhari. Study parameters like demographic profile of the patient like age, sex and diagnosis were recorded. Doctor details and patient details like age, sex and address were analyzed. Also, groups of drugs commonly prescribed, number of drugs per patient, drug profile and drawbacks of prescription if any were recorded and analyzed.Results: Most common group of drugs prescribed by physicians were Analgesics (21.84%), followed by Drugs for Peptic ulcer (17.92%) and Multivitamins/multimineral (14.70%). The average number of drugs prescribed per patient was 2.38. The incidence of Polypharmacy was common occurrence and some prescriptions had small drawbacks like absence of diagnosis, absence of doctor’s signature, etc.Conclusions: Authors conclude that most of the prescriptions which were analyzed at Ashwini Rural Medical College Hospital, Kumbhari, were according to the standard norms of WHO prescriptions and also most of the drugs prescribed were from the list of essential drug list. But still there is scope for improvement in prescription pattern
