STUDIES ON HETEROSIS FOR YIELD IN BRINJAL (Solanum melongena. L)

Heterosis breeding is one of the most efficient tools to exploit the heterotic response for various useful traits. The Line × Tester mating design was undertaken with seven lines and three testers were evaluated along with twenty one hybrids in randomized block design to estimate the magnitude of heterosis for yield and its yield contributing characters. The best way to utilize heterosis in crop is to generate F1 hybrids having maximum heterozygocity, thereby facilitating the identification and selection of hybrid vigor. The positive significant standard heterosis for fruit yield per plant was maximum with L3 × T1 (28.94%) followed by L7 × T3 (15.73%) and L7 × T1 (15.10%) respectively. Some of the promising hybrids have showed desirable heterosis for plant height, number of fruits per plant,1000 seed weight, seedling shoot length, seedling root length and seedling dry weight

Intelligent Buffer Management Algorithm to Prevent Packet loss in Mobile Adhoc Network

In a mobile ad hoc network, which is self-organized and operates without any fundamental infrastructure, packet transmission from the source node to the destination node is completed after sending the route request and route reply. A reliable path is then selected depending on the protocol choice.  Data that the sender intends to deliver is broken up into packets and given sequence numbers before being transmitted over the channel. With the aid of an internal buffer that helps to receive packets and forward them to the next destination, each and every packet travels along the allotted path until it reaches its destination. If there is more traffic on the MANET, the buffer may overflow, which will result in packet loss during transmission..  The source node must retransmit to the destination if any packets were lost during the initial transfer. This article proposes the Intelligent  Buffer Management (IBM) active buffer management algorithm to prevent such a scenario by enhancing the MANET nodes' buffers to prevent packet loss. The Network Simulator is used to help build this suggested approach, and the results are compared to those of the current buffer management method to show that IBM is superior

Studies on the Growth, Thermal and Optical Properties of p-methyl Anilinium Malate Single Crystal

International audienceSingle crystal of a novel p-methyl anilinium malate (PTM) was grown by slow evaporation method. Single crystal and powder X-ray diffraction studies confirm that PTM belongs to monoclinic system with centro-symmetric space group P21/c. FTIR spectral analysis showed the presence of functional groups in PTM compound. Thermal studies exhibit that PTM crystals are stable up to 166⁰C. UV-visible study showed the good transmission region, cutoff wavelength (206 nm) and band gap energy (5.8 eV) and photoluminescence studies explored its efficacy towards device fabrication. The third order nonlinear optical parameters such as the nonlinear refractive index (n2) = 3.41 × 10 −8 cm 2 /W, nonlinear absorption coefficient () =0.03 × 10 −4 cm/W and third order nonlinear susceptibility ( (3)) = 3.77 × 10 −6 esu of PTM crystal were estimated by using Z-scan measurement. Introduction. Recently, much attention has been paid on the development of a novel nonlinear optical (NLO) materials because of their optical applications, such as optical data storage, electro-optical modulation, optical switching, optical frequency doubling and optical communication. The organic compounds are having high nonlinear optical susceptibility (χ) than inorganic materials. The organic materials contain proton acceptor and donor groups positioned at either end of a suitable conjugation path. The efficient optical switching behaviour of third order nonlinear optical organic materials was investigated in recent years. The aim for designing the molecules with high third-order nonlinearity is to incorporate them into device applications. 4-methylaniline contains a proton acceptor amino (NH2) group, which can creates a strong hydrogen bond with organic acids and forms N-H-O, an anilinium group [1]. DL-malic acid one of the simplest chiral dicarboxylic acids, is a suitable building block in crystal engineering and it is used to create two-dimensional anionic networks held together by hydrogen bonds [2]. The structure of the p-methyl anilinium malate compound has been reported [3]. The systematic investigation has been carried on the growth aspects of PTM crystal. The spectral, optical, thermal properties of PTM crystal were studied by using various characterization techniques and results are reported

A boron-dipyrrin-mercury(II) complex as a fluorescence turn-on sensor for chloride and applications towards logic gates

Chloride (Cl-) plays an important role in many cellular responses, including control of membrane potential, neurotransmission, regulation of cell volume and charge balance. Due to its physiological relevance, there is a growing need for improved optical sensors that can detect Cl- ions in biological and environmental samples. Herein, we have developed new N-acylhydrazone substituted BODIPY-mercury(II) based fluorescent turn-on sensors 1-Hg2+ and 2-Hg2+, which showed remarkable selectivity and specificity towards Cl- ions under physiological conditions. The new BODIPY compounds 1 and 2 were synthesized by treating their corresponding 3,5-diformyl BODIPYs 3 and 4 with isonicotinohydrazide in one step under simple reaction conditions. Compounds 1 and 2 absorb in 615-650 nm and emit in 625-660 nm regions. BODIPYs 1 and 2 showed exclusive sensing towards Hg2+ and formed 1-Hg2+ and 2-Hg2+ complexes, respectively, which resulted in the quenching of fluorescence. Job's plot analyses and HR-MS studies supported the formation of 1-Hg2+ and 2-Hg2+ complexes. Complexes 1-Hg2+ and 2-Hg2+ were found to be exclusive fluorescence turn-on sensors for chloride ions. Upon addition of Cl- ions to 1-Hg2+ and 2-Hg2+ complexes, the mercury(II) ions were extracted from the complexes by releasing the free BODIPYs 1 and 2 which reflected in the significant enhancement of fluorescence intensity (22-fold) with a detection limit of 108 nM. The reversibility and reusability of sensors for the detection of Hg2+ and Cl- ions were tested for six cycles. Interestingly, the sensor can be used to construct an IMPLIES logic gate system as demonstrated in this paper. Furthermore, the probe is cell membrane-permeable and can readily be used to detect the intracellular Cl- ions
