Custard apples have been part of human diet for ages due to its nutritional and medicinal values. But consumption of these fruits generates peel wastes that could bring about environmental pollution if not properly managed. Towards recycling of wastes and avoiding littering and waste-related environmental degradation, this study was carried out to explore the sugar components of custard apple peels with a view to establishing their raw material potentials. Selected samples are cut into small bits, dried, powdered and were subjected to sensitive extraction procedure developed using the mixture Methanol -Dichloromethane - Water (MDW) (0.3:4:1v/v) and MeOH-H2O phase was assayed for sugar analysis. The extracted sugars were put through chemical characterization procedures for purposes of separation and identifying its components. The various standard sugars were spotted using the solvent system n-butanol - acetone - diethylamine - water (10:10:2:6, v/v) in the cellulose layer for TLC analysis indicated the presence of lactose, sucrose, galactose and glucose.

Three independent molecules comprise the asymmetric unit of the title compound, C10H19N5O2, (systematic name: 4-amino-N-tert-butyl-3-isopropyl-5-oxo-4,5-dihydro-1H-1,2,4-triazole-1- carboxamide). In all three molecules, the triazole ring and the carboxamide group are almost coplanar [within 4.0-5.9 (9)°], particularly because of the formation of an intramolecular N-H⋯O hydrogen bond. On other hand, the orientation of the isopropyl group varies significantly from molecule to molecule. The crystal packing is dominated by N-H⋯O and N-H⋯N hydrogen bonds, which connect the molecules into infinite chains along [010].

In the title salt {systematic name: 4-diphenylmethyl-1-[(E)-3-phenylprop-2- en-1-yl]piperazin-1-ium 2,4,6-trinitrophenolate), C26H 29N2+·C6H2N 3O7-, the cinnarizinium cation is protonated at the piperazine N atom connected to the styrenylmethyl group; the piperazine ring adopts a distorted chair conformaiton. In the crystal, bifurcated N - H⋯(O,O) hydrogen bonds link the components into two-ion aggregates.

Astock solution of manganese(III) acetate in aqueous acetic acid has been prepared using a standard electrochemical method. The nature of the oxidizing species present in manganese(III) solutions has been characterized by spectrophotometric and redox potential measurements. Kinetics of oxidation of DL-alanine (Ala) by manganese( III) in aqueous acetic acid solution at 313Khave been investigated. The experimental rate law is: rate = k'[Mn(III)] 0.5[Ala] 0.9 [OAc-]y 0.5/[H+] 0.5, where each species shows a fractional order. Effects of varying ionic strength, solvent composition, and the added ions such as fluoride, chloride, and perchlorate have been investigated. Activation parameters have been evaluated using Arrhenius andEyring plots.Amechanism consistentwith the observed kinetic data has been proposed and discussed. A suitable rate law has been derived based on the mechanism. Copyright © Taylor & Francis Group, LLC.

A rapid, sensitive extraction method was developed using the mixture methanol-dichloromethane-water (MDW) (0.3:4:1v/v/v) and MeOHH2O phase was assayed for sugar analysis. Photodiode-array detection (DAD) has been used to prove the extracted compound is UV inactive, high-performance liquid chromatography (HPLC) with evaporative light scattering detector (ELSD) coupled to electrospray ionization mass spectrometric (ESI-MS) detection in the positive ion mode gave MS and MSn fragmentation data, which were employed for their structural characterization. Various standard sugars were spotted using the solvent system n-propanol-ethyl acetate-water (13:37:7, v/v/v) in the cellulose layer for TLC analysis which indicated the presence of aldohexose glucose and ketohexose fructose. This is the first assay of the sugar profile of the black grape peels, which can be further developed for characterization and evaluation of their quality with regards to their sugar composition.

Effects of Sodium and Potassium in diet to determine baby gender in hamster have been investigated. Diabetes mellitus is a chronic, widely spread disease in living species. Sex determination has scientific basis for prevention of genetic diseases in addition to social backgrounds.36 hamsters (obtained from veterinary college Bangalore), were divided in to three groups in the ratio male to female 1:5. The first group was made diabetic with Na and K, the second group was non diabetic with Na and K, group third was control unit (Non-diabetic without Na and K). It was found that the delivered offspring's male to female ratio were 4:1, 3.6:1 and 1.02:1 for the first, second and third groups respectively. Also, it was found that non diabetic hamster fed with normal food yields maximum numbers of offspring (83), while diabetic hamster fed with Na and K yields and diabetic hamster with Na and K yield lowest numbers of offspring (50).

Impact of calcium and magnesium in diet to determine the baby gender in high-sugar hamsters has been investigated. Diabetes mellitus is a chronic, widely spread disease in living species. Sex determination has scientific basis for prevention of genetic diseases in addition to social backgrounds.30 hamsters (obtained from veterinary college Bangalore), were divided in to three groups at the rate male to female 1:5. The first group was made diabetic with Ca and Mg, the second group was non diabetic with Ca and Mg, group third was control unit (Non-diabetic without Ca and Mg). It was found that the delivered offsprings female to male ratio were 3.6:1, 2.61:1 and 1.04:1 for the first, second and third groups respectively. Also, it was found that non diabetic fed with normal food yields maximum numbers of offspring (90), while non diabetic fed with Ca and Mg yields 83 and diabetic with Ca and Mg yield lowest numbers of offspring (70).

This paper presents a 5 - bit 4.87GSps Flash ADC design using 45-nm GPDK CMOS technology library. The designed system consists of two main blocks as comparator array and digital decoder. The digital decoder contains 2:1 MUX based 1 - of - N decoder and Regenerative Buffer units. As a result, active die area and the power consumption are reduced in addition to increase in sampling frequency. The power supply voltage range for the overall system is ± 1.8V. The simulation results include maximum power consumption of 0.24 mW. The Conversion time 204p sec, the measured DNL and INL to less than 0.02LSB and 0.1LSB. © 2015 IEEE.
