Birds show sign of differences in behavior and physiology during life history states (LHSs) which reflect the adaptive strategy for continued existence. The long-distance night migratory songbirds undergo behavioral shifts journey; from inactivity to intense activity. Here, we aim investigate seasonal responses blueprint activity rest different (LHS) blackheaded (Emberiza melanocephala; group 1) redheaded Buntings bruniceps; 2) that inhabit overlapping breeding wintering grounds. Adult...
Phase diagram of benzoic acid (BA)–o-chloro (o-CBA) system has been studied by thaw melt method and the results show formation a simple eutectic mixture. Heats fusion values components mixture were determined with help differential scanning calorimeter. Excess Gibb's free energy (GE), excess enthalpy (HE), entropy (SE) mixing pre-, post-, calculated. FT-IR spectroscopic studies ab initio calculations done to have an idea about nature interaction between molecules in Linear velocities...
The phase diagram of the benzamide + o-chlorobenzoic acid system has been studied by thaw−melt method, and results show formation a simple eutectic mixture. Values enthalpies fusion pure components mixture were determined from DSC studies. Excess Gibb's energy (GE), excess enthalpy (HE), entropy (SE) mixing pre-, post-, also calculated using activity coefficient data.

Introduction: Light is the primary source of energy and regulates seasonal changes in physiology behavior. The role photoperiod has been much investigated several bird species, but illumination adaptations passerine finches less understood. We, therefore, effects illuminance on migratory a Palearctic-Indian finch, redheaded bunting (Emberiza bruncieps). Methods: Photosensitive buntings maintained under short days (8L:16D) were divided into three groups receiving 5, 25, 100 lux white daytime...
Phase diagrams of naphthalen-2-ol + 1,3-dinitrobenzene have been investigated by the thaw melt method. The results show formation a simple eutectic mixture. Enthalpy fusion values pure components and mixture were obtained from DSC studies. Linear velocity solidification was determined at different undercooling rates. linear crystallization indicate nonideal nature in melt. anisotropic isotropic crystallizations naphthalen-2-ol, 1,3-dinitrobenzene, studied. flexural strengths components,...
Vanillin reacts with p-anisidine in 1:1 molar ratio the solid and molten states, microwave oven solution. In all cases, reaction occurred formation of N-(4-methoxy phenyl)–4-hydroxy-3-methoxy phenyl methanimine (NHM) water. Single crystal X-ray analysis shows that NHM crystallizes chiral orthorhombic space group P212121. An optimized geometry was computed by using density functional theory. case solid-state reaction, it is proposed a thin layer water molecules formed at junction vanillin...
BACKGROUND: The maintenance of oral hygiene and subsequent health related issues in visually handicapped children is a challenging task. Hence, tools must be used to ensure good these children. study aimed analyze the effectiveness preventive programs on using specialized audio tactile aids impaired school MATERIALS AND METHODS: 100 were selected for study. They divided into two groups: Group A (Training Braille) B (training by means aids). Children trained appropriate was assessed Plaque...
Over millennia, environmental light-dark cycle provided a dependable indicator of time day. It showed the effects light on physiology and behaviour in every animal. Furthermore, sunrise sunset (dawn dusk) usually refer to duration day length when upper edge sun’s disk is horizon. Interestingly, before onset after there twilight dusk), during which natural by atmosphere. Evidences suggested that transitions (twilight) are more essential synchronize organisms circadian (circa = about; dian...
Abstract The numerical order of the chemical shift an X‐ray absorption edge a metal when it undergoes combination and forms compound is calculated by calculating binding energy core electrons. It found that in corresponds well with shift.
Growing markets like automotive, IoT and networking are pushing the reliability requirements of electronic components present in them to extreme levels. Such applications require specialized ASICs (Application Specific Integrated Circuits) process huge amounts data environments over extended periods time, or for almost continuous use shorter periods. While predicting functional behavior such complex System on Chip (SoC) systems requires significant verification effort with help extensive...
Leucism is a genetic trait caused by lack of melanin pigment in an animal’s skin, feathers, or fur. Unlike albinism, which defined total synthesis, leucism characterised partial loss pigmentation. The definitions and various aspects albinism are exceedingly vague. This very first documented report leucistic Jungle Babbler (Turdoides striata) Northern India was made Lucknow, Uttar Pradesh. More study needed to look at the additional places occurrence these individuals, as well basis Babblers.
Photoperiodism is a prime selective force and in response to photoperiod other supplementary environmental cues, birds exhibitbehavioral physiological responses. Birds have developed specialized temporal programming for the adaptation their activities during 24-h of periodicity. To maintain successful survival progeny, they use both cues endogenous cycles suitable time window year. These timing mechanisms commonly involve an internal molecular oscillator which we called as ‘clock’ (s) that...
The role of nanomaterials is very important due to the fact that they possess large surface area volume ratio, ease functionalization, fast electron transfer kinetics, catalytic activity and biocompatibility also selectivity specificity. With advent nanotechnology, its application incatalysis sensing entering a new era for design innovative sensors can sense low level concentration analyte by portable sensor device which was hardly possible earlier. Sensors have fascinated much consideration...
