Magnetocaloric effect and critical behavior near the paramagnetic to ferrimagnetic phase transition temperature in TbCo2-xFex

Magnetocaloric effect (MCE) in TbCo2-xFex has been studied by dc magnetization measurements.On substituting Fe in TbCo2, not only the magnetic transition temperature is tuned to room temperature, but also the operating temperature range for MCE is increased from 50 K for TbCo2 to 95 K for TbCo1.9Fe0.1. The maximum magnetic entropy change (-{\Delta}SM) for TbCo1.9Fe0.1 is found to be 3.7 J kg-1 K-1 for a 5 T field change, making it a promising candidate for magnetic refrigeration near room temperature. The temperature dependent neutron diffraction study shows a structural phase transition (from cubic to rhombohedral phase with lowering of temperature) which is associated with the magnetic phase transition and these transitions broaden on Fe substitution. To investigate the nature of the paramagnetic to ferrimagnetic phase transition, we performed a critical exponent study. From the derived values of critical exponents, we conclude that TbCo2 belongs to the 3D Heisenberg class with short-range interaction, while on Fe substitution it tends towards mean-field with long-range interaction. The derived values of critical exponents represent the phenomenological universal curve for the field dependence of {\Delta}SM, indicating that TbCo2 and TbCo1.9Fe0.1 belong to two different universality classes.Comment: 12 figure

Conservative non-surgical management of a large periapical lesion using a calcium hydroxide based sealer for obturation: a case report

Introduction: Periapical lesions often result following dental caries, pulpal infection or trauma. Their management may include both sugicl and non-surgical endodontic management. Case report: The aim of this case report was to report the successful non-surgical management of a large periapical lesion in relation to maxillary right central and lateral incisors using calcium hydroxide based sealer Sealapex for obturation. The case was periodically reviewed and showed signs of almost complete periapical healing after six months. Discussion: Traditionally, calcium hydroxide is the material of choice for inducing periapical healing when used as an intracanal medicament or as a root canal sealer. In this case, the non-surgical healing of the large periapical lesions using a calcium hydroxide based sealer provided favorable clinical and radiographic response. Conclusion: The calcium hydroxide based sealer when used for obturation in non-surgical management of a large perapical lesion showed a successful treatment outcome

Magnetic properties of Hydrogenated Li and Co doped ZnO nanoparticles

The effect of hydrogenation on magnetic properties of Zn0.85Co0.05Li0.10O nanoparticles is presented. It was found that the sample hydrided at room temperature (RT) showed weak ferromagnetism (FM) while that hydrided at 400oC showed robust ferromagnetism at room temperature. In both cases reheating the sample at 400oC in air converts it back into paramagnetic state (P) completely. The characterization of samples by X-ray and electron diffraction (ED) showed that room temperature ferromagnetism observed in the samples hydrogenated at RT is intrinsic in nature whereas that observed in the samples hydrogenated at 400oC is partly due to the cobalt metal clusters.Comment: 10 pages, 3 figure

Bank Form Classification using Document Layout Analysis and Image Processing Techniques

Every day thousands of forms are filled out and submitted across the world, in banks, post offices, government organizations, educational institutions etc. These include electronic forms as well as physical forms. All of these forms irrespective of their origin are at some stage made digital and stored electronically to address issues of physical storage, form degradation and data accessibility. Document layout analysis is a basic step in converting document images into electronic form. This conversion is laborious and can be made more efficient (in terms of throughput and human resource) by automating most of the conversion process using document layout analysis techniques. Document classification is an important step in Office Automation, Digital Libraries, and other document image analysis applications. Physical forms require human supervision for any operations done on the form. Digitization of these forms reduces human resources, also reduces any human redundancy involved with the operation on the physical forms. This paper addresses the initial stage of this automation, namely, bank form classification and decipherment of fields. The former recognizes the type of the bank form and the latter extracts regions of useful data from the classified bank form. The proposed work aims to provide accurate bank form classification along with noise removal, skew detection and correction, finally layout analysis is carried out to extract fields like name, address, signature from the classified forms

A study of uterine balloon tamponade for the management postpartum haemorrhage using Bakri balloon

Background: PPH is the most common cause of maternal morbidity and mortality around the world. Incidence of PPH is 2-4% following vaginal delivery and 6% following cesarean delivery in India. Uterine atony is the most common cause of PPH. Treatment of PPH involves medical treatment and surgical management. In between medical and surgical management of PPH comes uterine balloon tamponade which is simple, less invasive and can be managed with minimal training.Methods: A retrospective cohort study was done for 2 years at Vanivilas hospital, Bangalore medical college and research centre, Bangalore, Karnataka. Cases of atonic PPH managed using Bakri balloon were included in the study. The objective of the study was to study the effectiveness of uterine balloon tamponade using Bakri balloon in the management of atonic PPH and to study the maternal outcome.Results: In this study total of 50 cases were included. Women were in the age group of 18 to 33years. Regarding obstetric history, 22 (44%) were primigravida and 28 (56%) was multigravida. Among these 50 cases 8 (16%) women had undergone caesarean delivery and 42(84%) had vaginal delivery. All women received blood transfusion, 17 (34%) received blood and blood components (like PRBC, FFP AND platelets) and 33 (66%) cases received only PRBC transfusion. In these 50 cases, 32 (64%) required ICU admission for monitoring, remaining 18 (36%) were monitored in the labor-room. Bakri balloon was effective in 49 cases among 50. Success rate was 98%.Conclusions: Intrauterine balloon tamponade using Bakri balloon is effective for control of atonic PPH in majority of cases.

A CASE REPORT OF SHADBINDU TAILA NASYA AND TRIKATU DHOOMAPANA ON APEENASA-ATROPHIC RHINITIS

Acharya Sushruta stated 28 Nasagata rogas. Out of these 28 Nasagata rogas some features of Pootinashya, Dushtha Pratishyaya and Apeenasa are similar to the clinical features of Atrophic Rhinitis (AR). Apeenasa is a Nasagata Roga characterized by nasal obstruction, running nose, Dryness of nose, anosmia, and loss of taste. This condition can be co-related with Atrophic Rhinitis. Though there are many modalities described in modern ENT, still it is not possible to cease the Permanent Impairment. In Ayurved many modalities are being described for Urdhwajatrugata Rogas and for Nasagata Vikara. Among them Nasya (administered of drugs in to nasal cavity) is best. As it is a Kapha Pradhana Vikara, Katu Dhoomapana can also be added to this procedure. The Nashya procedure is explained by Brihatrayees. The complete procedure of Nashya includes Poorva Karma (Snehana and Swedana), mobilizes the Doshas to the site of elimination and causes vasodilatation which helps in elimination of Doshas and provides better channel for absorption of the Oushadhi. Pradhana Karma (Nashya) eliminates the Doshas. Kavala as Paschat Karma eliminates the remaining Doshas and causes better absorption of the Oushadhi which ultimately eliminates the symptoms of the disease. A clinical observation has shown effective result in the treatment of AR with Shadbindu Taila Nasya and Trikatu Dhoomapana. And here we are revalidating the statement of our Acharyas. A case report of a female, aged 38 years with complain of nasal obstruction, foul smell from nose, anosmia, headache, nasal discharge, sneezing and general weakness has been presented here
