An Application of Interval-Valued Fuzzy Soft Sets in Medical Diagnosis

Abstract The concept of soft set is one of the recent topics developed for dealing with the uncertainties present in most of our real life situations. The parametrization tool of soft set theory enhance the flexibility of its applications. In this paper we extend Sanchez's approach for medical diagnosis using interval-valued fuzzy soft sets and exhibit the technique with a hypothetical case study

Decision making under incompleteness based on soft set theory

[EN]Decision making with complete and accurate information is ideal but infrequent. Unfortunately, in most cases the available infor- mation is vague, imprecise, uncertain or unknown. The theory of soft sets provides an appropriate framework for decision making that may be used to deal with uncertain decisions. The aim of this paper is to propose and analyze an effective algorithm for multiple attribute decision-making based on soft set theory in an incomplete information environment, when the distribution of incomplete data is unknown. This procedure provides an accurate solution through a combinatorial study of possible cases in the unknown data. Our theoretical development is complemented by practical examples that show the feasibility and implementability of this algorithm. Moreover, we review recent research on decision making from the standpoint of the theory of soft sets under incomplete information

ANTIOXIDANT, ANTIBACTERIAL AND HEPATOPROTECTIVE ACTIVITIES OF CISSUS REPENDA VAHL ON CARBON TETRACHLORIDE (CCL4) INDUCED LIVER DAMAGE IN BIRD COLUMBA LIVIA

Objectives: Drug induced liver damage has been identified as one of the major global diseases in recent years. The plant derived alternative medicines are considered as the most effective solution for combating such liver diseases. In the present study, the antioxidant, antibacterial and hepatoprotective property of Cissus rependa Vahl. was evaluated. Methods: Anti-oxidant activity of the extracts were spectrophotometrically determined using ascorbic acid as standard. Determination of antimicrobial activity followed by Agar well diffusion method and nutrient content by standard laboratory methods. The activity of the two enzymes were measured spectrophotometrically (520 nm) following the DNPH method with minor modification   Results: The study shows that the aqueous extract of the plant leaf contains a good number of phytochemicals such as cardiac glycoside, saponin, alkaloid etc. as well as antioxidant with respect to the scavenging activity against free radicals DPPH (79.79 %) and ABTS (84.6%) which were roughly comparable to that of ascorbic acid (88.2% and 83.0 % respectively). The plant extract also exhibited potent antibacterial activity against S. aureus and P. vulgaris indicating its bactericidal or bacteriostatic properties. The study also indicates that the oral feeding of aqueous extract of the plant could reduce the CCl4 induced chronic damage of hepatic tissue in bird (C. livia) which was reflected by the decreased level of total soluble protein as well as activity of the enzymes Aspertate aminotransferase (AST) and Alanin aminotransferase (ALT) in both liver and muscle tissues of EX (experimental) group treated with plant extract as compared to that of untreated birds PC (positive control) group which otherwise had highly increased due to CCl4 induced tissue damages. Key words: Antioxidants, Cissus rependa Vahl, hepatotoxicity, Aspertate aminotransferas and phytochemicals

Ruthenium monoterpyridine complexes with 2,6-bis(benzimidazol-2-yl)pyridine: Synthesis, spectral properties and structure

Ruthenium monoterpyridine complexes with the tridentate 2,6-bis(benzimidazol-2-yl)pyridine (LH2), [Ru(trpy)(LH2)](2+), [1](2+) and [Ru(trpy)(L2-)], 2 (trpy = 2,2':6',2 ''-terpyridine) have been synthesized. The complexes have been authenticated by elemental analyses, UV-Vis, FT-IR, H-1 NMR spectra and their single crystal X-ray structures. Complexes [1](2+) and 2 exhibit strong MLCT band near 475 and 509 nm, respectively, and are found to be very much dependent on solution pH. The successive pH dependent dissociations of the N-H protons of benzimidazole moiety of LH2 in [1](2+) lead to the formation of 2. The proton induced inter-convertibility of [1](2+) and 2 has been monitored via UV-Vis spectroscopy and redox features. The two pK(a) values, 5.75 and 7.70, for complex [1](2+) have been determined spectroscopically. (C) 200

Not AvailableThe present study was carried out in the upper stretch of Jenam river, a tributary of River Barak, which flows through Dima Hasao district of Assam. Conventional fishing gears are not found to be very effective in fast flowing hill streams. Therefore, the local inhabitants of such areas generally use many traditional fish catching devices suitable to the location for catching fishes from these fast flowing hill streams. One such traditional fishing method namely Hebua and Heba operated by Jeme-Naga tribe is discussed in the present study. These traditional devices generally developed based on behavioural biology of the fish species and evolved over many generations. Participatory Rural Appraisal (PRA) methodology was adopted to collect information about this indigenous fishing method. A total number of 26 fisher folks as well as village elders were consulted through one to one interaction for detail documentation of the fishing method. In both these fishing methods, fishes are trapped by altering their path of movement and using the water current to the fullest extent to prevent their escape. Upward migratory behaviour of monsoon season and downward migratory behaviour of winter of hill-stream cyprinid fishes is effectively utilised in the operation of these fish trapping devices. The present study provides an insight to these eco-friendly, cost-effective and energy-efficient indigenous fishing methods.

INTRODUCTION DimaHaso district formerly known as North Cachar Hills lies between 24 o 57´N57´N to 25 o 43´N latitudes and 92 o 32É to 93 o 28É longitudes in southern part of Assam. This hill district with an area of 4890 km 2 , constituting roughly 6.24% of the total area of the state is one of the least populous districts of Assam. Borail hills cover a major portion of this district. Dima Hasao district shares its boundary with the states of Nagaland and Manipur in east; Meghalaya and Karbi-Anglong district in west; Karbi-Anglong and Nagaon districts in north; and Cachar district of Assam in south. Eleven different ethnic tribes namely Dimasas, Jeme-Nagas, Hmars, Kukis, Biates, Hrangkhols, Khelmas, Jaintias, Karbis, Vaipheis and Rongmei Nagas along with a sizeable population of non-tribals constitute the demographic profile of this hill district. Kapili, Dehangi, Diyung, Jatinga, Jenam, Mahur and Langting are the main rivers flowing through this district and drain ultimately into Brahmaputra and Barak rivers. These rivers are a rich repository of aquatic biodiversity particularly hill-stream fishes. Ethnic tribes of Dima Hasao employ a variety of fishing techniques in these rivers. Many of such fishing methods are based on indigenous knowledge and bear the distinction of being evolved in a particular community passed on through generations. Several documentations have been made pertaining to Indigenous technical knowledge (ITK) associated with fishing techniques in Assam and North east India [1][2][3][4][5][6][7].
