Abstract

This paper intends to examine the relationship between team leaders' Emotional Intelligence competence and their teams' emotional intelligence. Based on exisiting literature reviews, it is assumed that a team leader's Emotional Intelligence (EI) will influence the development of Group Emotional Intelligence (GEI). The primary data was collected for this study by using two instruments. The emotional intelligence of the team leaders was assessed using Emotional Social Competency Inventory (ESCI). The permission for using Emotional S ocial Competency Inventory was obtained from the Hay Group (Boston). The group Emotional Intelligence was measured using the inventory Emotional Competent Group Norms (ECGNs). The Emotional Intelligence of the teams was measured as norms instead of competency. The instrument was designed and tested by Druskat, Wolff, Koman and Messer. All participants in this study were team leaders, members, managers or supervisors for a particular team in the call centre. The data was collected from over 100 teams from call centers in Sutherland, Jeppiaar Technologies, Airnos, Ael Data, FSS, Mobinus, Infoflex&Quiescent technologies. The relationship between the team leaders' Emotional Intelligence and the emotional competent group norms of the teams was analyzed using correlation and regression analysis. This analysis indicates both individual and collective impacts of both ESCI and ECGNs inventory. The proposed model establishes the relationship between and among the team leaders' emotional intelligence competencies and emotional competent group norms of the teams.

Abstract

Ecofriendly methods for the management of grain discolouration in rice using plant oils, plant extracts and bacterial antagonist were tested in pot culture and field experiments. The field fungi such as Drechslera oryzae, Curvularia lunata and Fusarium moniliforme were predominantly associated with the grain discolouration in rice. In pot culture experiment, post inoculation spraying of neem oil 80 EC (3%) was highly effective in reducing the grain discolouration which was on par with carbendazim (250 g ha^-1), rhizome extract (10%) of Curcuma longa, leaf extract (10%) of Nerium oleander, Pseudomonas fluorescens (Pf1) (10⁹ cfu ml^-1) and leaf extract (10%) of Vinca rosea. In the field, spraying of neem oil 80EC (3%) at flowering stage and ten days later reduced the grain discolouration from 21.60 to 11.45 per cent which was on par with carbendazim (250 g ha^-1), rhizome extract (10%) of C. longa, leaf extract (10%) of N. oleander and P. fluorescens (Pf1) (10⁹cfu ml^-1). There was also significant increase in the grain yield due to these treatments compared to control.

Abstract

Four different organic substrates, viz., decomposed coir pith, dried cow dung, rice bran and tea waste, were tested tor the growth of Trichoderma viride (isolate t). The population (CFU) of T. viride on various substrates was estimated at 20^th, 30^th, 40^th and 60^th day after inoculation by serial dilution plate technique. The population of T. viride was highest on 20^th day in sterilized tea waste (236.30 × 10⁶ cfu), followed by rice bran (152 × 10⁶ cfu), decomposed coir pith (44.35 × 10⁶ cfu), talc (36 × 10⁶ cfu) and dried cow dung (20 × 10⁶ cfu). Sterilized substrate was favourable for the multiplication of T. viride except for dried cow dung. The population increased in all the substrates except talc on 30^th day and declined from 40^th day onwards.

Abstract

Background/Objectives: The experimental investigations are carried out to study the effect of agricultural waste in PCC structure by partial replacement of cement and aggregate with wastes. The agricultural and industrial wastes used are Bagasse Ash, Fly ash and Coconut shell. Here the Bagasse ash and coconut shell has been physically characterized, and partially replaced by weight of cement and aggregate in concrete. Methods/Statistical Analysis: This study has been aimed to evaluate the strength of the concrete by performing standard tests like compressive strength, split tensile strength and flexural strength at the age of 3, 7 and 28 days and physical properties test were also conducted and compared. The bagasse ash and coconut shell have been replaced partially with the concrete of about optimum of 25% respectively. Instead of cement, bagasse ash is utilized with varying proportions and the strength values are evaluated and tabulated. Similarly coconut has been utilized with the conventional concrete for the replacement of coarse aggregate. Findings: The strength parameters are evaluated with the specimen of bagasse ash and coconut shell.In this study, bagasse ash has been partially replaced with the cement to determine the physical and chemical properties of the concrete and then it is compared with the conventional concrete. Similarly coconut shell has been replaced partially with the coarse aggregate for evaluating the strength parameters. In past research, the bagasse ash replacement was given the results of about 90% with 15% of replacement of cement with bagasse ash.In this present study, obtained the optimum strength of about 80% with the replacement of bagasse ash as of about 25%. The utilization of more than 25% of bagasse ash in concrete, strength is gradually reduced with the target strength of conventional concrete. Applications/Improvements: Further research in this study is to use the chemical admixture to improve the bonding strength,then the strength might have been increased with that of conventional concrete. The major application of this concrete is to use as a constructional material for the non structural elements like kitchen slab, man hole cover and compound walls.

Abstract

In Tamil Nadu state, Thoothukudi district ranked second in banana production and especially the Tamirabarani tract of Thoothukudi and Tirunelveli districts are known for the production of various banana cultivars like Rasthali, Andhra Kozhi, Karpooravalli, Neypoovan, Poovan, Peyan and Chakkai. Among these varieties, cultivation of Rasthali faces 50-60% yield loss due to the incidence of Fusarium wilt disease. As the farmers have been practising ratooning for 6-7 year continuously which enhances the inoculum load of the pathogen and make the plantains succumb to Fusarium oxysporum f. sp. cubense (Foc). Studies carried out on different treatments in the management of Fusarium wilt of banana, Trichoderma sp. Tsp1(ALG) showed a maximum reduction of mycelial growth of Foc (72.18%) over control which was on par with Pseudomonas fluorescence 1(Pf1). Under pot culture conditions the combination of three treatments, Tsp1(ALG)+Pf1+ neem cake excelled and showed an 80% reduction of wilt incidence. A multifaceted approach comprising the application of biocontrol agents (Trichoderma sp.) + Pseudomonas sp. 1 (TNAU) and organic amendments was found to be the best management practice in containing the wilt.
