Multiple board appointments and firm performance in emerging economies: Evidence from India
No full textThe relation between multiple directorships, busy directors and firm performance has been researched predominantly in the context of developed economies, notably the US. This paper extends the existing literature on multiple directorships in two ways; first, by providing additional evidence on its effect on firm performance, but with respect to an emerging economy, India, and secondly, by suggesting an alternative measure of directorial "busyness" that is more general in its applicability compared to those that have been applied in the existing literature. Using a sample of 500 large firms from the Indian corporate sector for the year 2002-03, the paper finds multiple directorships by independent directors to correlate positively with firm value thereby supporting the "quality hypothesis" that busy directors are likely to be better directors, a result that is different from the existing evidence on busy directors. Multiple directorships by insider directors are, however, negatively related to firm performance. Estimation of group and non-group companies separately reveals that the quality effect of independent directors persists for the former but disappears for the latter. In general, the results suggest that the relation between "busy" directors and firm performance may depend on the institutional context and on the type of directorMultiple Directorships, Busy Directors, Firm Performance

Addison′s disease
No full textAddison′s disease is a rare endocrinal disorder, with several oral and systemic manifestations. A variety of pathological processes may cause Addison′s disease. Classically, hyperpigmentation is associated with the disease, and intraoral pigmentation is perceived as the initial sign and develops earlier than the dermatological pigmentation. The symptoms of the disease usually progress slowly and an event of illness or accident can make the condition worse and may lead to a life-threatening crisis. In this case, several oral as well as systemic manifestation of the Addison′s disease was encountered

Carbon-carbon bond cleavage via carbon centred radical in strained tricyclo[5.2.1.0<SUP>2,6</SUP>]decenes. A facile route to bridged eight membered rings related to taxanes
No full textTributyltin hydride reaction of the tricyclo[5.2.1.02,6]decenes 5, 16 and 23 bearing a halo-carbonyl moiety has been shown to involve C---C bond cleavage as the major reaction path leading to bridged eight-membered rings 12, 17 and 24. In contrast the halo-carbonyl derivatives 8, 33 and 36 undergo only reduction of the carbon-halogen bond. The ring cleavage observed has been attributed to the release of strain arising from nonbonded interaction as well as strain associated with norbornene
Design of fractional-N frequency synthesizer for 2.4/5 GHz wireless local area network
No full textFrequency synthesizers are widely being used for generating local oscillators for majority of RF, wireless, communication, and navigation systems for the last few decades. Phase-locked-loops (PLL) on the other hand are one of the fundamental portions of any digital/mixed-signal devices in addition to the previously mentioned systems. In this thesis work, a PLL based fractional-N frequency synthesizer for 2.4 GHz and 5 GHz wireless local area network (WLAN) in 0.18 μm CMOS-RF process has been proposed. With the adoption of a MASH 1-1-1 delta-sigma modulator facilitating fractional division ratios through a programmable divider, the frequency synthesizer differs from its integer-N counterpart in its higher reference frequency, wider loop bandwidth, faster settling time, and better phase noise and suppression of spurious tones. The synthesizer consists of several blocks, including a wide range LC-tuned voltage controlled oscillator (VCO), divide by 16 – 252 programmable divider, dead-zone free phase-frequency detector (PFD), low mismatch high swing cascode charge pump (CP), 3rd order loop filter (LF), and a 3rd order MASH delta-sigma modulator (DSM)—all of which have been designed and constructed in both transistor and layout levels. SPICE (BSIM3) level simulations have been performed for all the individual blocks as well as the complete frequency synthesizer for extracting transient, DC, periodic-steady-state, and phase-noise analyses results. Overall, with 1.2 V supply voltage, the 0.628 mm X 0.594 mm fractional-N frequency synthesizer achieves “locked” state in approximately 2 μs and produces approximately -111 dBc/Hz phase noise at 1 MHz offset (excluding the MASH modulator) while consuming about 20.76 mW of power.M.S.Includes bibliographical referencesby Subrata Debnat
