In this research, Eu3+ activated and Dy3+-co-doped Y2O3 based phosphors have been synthesized by solid-state reaction method under open atmosphere. The host lattice is composed of 0.25 moles of Sc2O3 which is added to phosphor composition. Thus, Sc3+ substitution of Y3+ ions is implemented to form Y1.40Sc0.50O3 host lattice. The thermal analysis (DTA/TG) have been carried out from 50 degrees C to 1400 degrees C for preliminary examination of thermal behavior of phosphors during heat treatments. After the heating process, the phase formations are characterized by X-ray diffraction resulted as Y2O3 single phase cubic structure. The effects of Eu3+ and Dy3+ dopant ions on the photoluminescence and phase formation properties of the hosts are investigated and determined as Dy3+-co-doped phoshor has the reduced excitation/emission intensities as well as decay lifetimes.

India owns the best buffalo breeds, particularly Murrah which is famous all over the world for high milk production. India’s white and pink revolution cannot be imagined without the contribution of buffalo and to achieve these, the best productive animals need to be produced through scientific interventions. Animal cloning is a technique used to produce multiple copies of the best animals without normal reproduction. In India, buffalo cloning has already happened and India’s first cloned buffalo was produced in 2009. Later, several buffalo clones were produced and attempts are ongoing to produce stock of more elite animals. Buffalo cloning has made its way from scientific curiosity to farmer’s farm. In this viewpoint article, we provide an overview of the progress of buffalo cloning and we discuss some of the public perceptions of animal cloning such as aging and food safety of cloned animal products.

2,4-Dimethyl-6-hydroxyacetophenone oxime and 3,5- dibromo-2,4-dimethyl-6-hydroxyacetophenone oxime act as very good reagents for the extraction and separation
of Cu(II), Ni(II), Co(II), Fe(III) and Mn(II). Addition of diethylamine as a synergist in the extraction system, not only increases the per cent extraction of the metals but also the molar absorbances of the complexes. The separation of the metals from one another, viz., Cu(II) from Ni(II), Cu(II) from Co(II) and Cu(II) and Ni(II) from Cr(III) becomes far more easier in the presence of diethylamine.

Chelating ion-exchange resins (2,4-DPPO-F) have been synthesized by the condensation of 2,4-dihydroxypro-piophenoneoxime (2,4-DPPO) and formaldehyde (F) in the presence of oxalic acid as catalyst with varying molar ratios of the reacting monomers. The resins have been characterized by elemental analyses, IR spectra, viscosity and TGA The molecular weights of resins have been determined by nonaqueous conductometric titrations and vapour pressure osmometry (VPO). Chelation ion-exchange properties have also been studied employing the batch equilibration method.

About 30 years ago the idea of cultural distance between peoples structure of thought and the science was proposed. Over the years it crystallised. This article presents major findings of the surveys that were conducted in India, spanned over twenty-five years. It is argued that cultural distance varies depending upon the nature of scientific information. Mapping cultural distances of specific scientific information for distinct target groups could help planners and communicators of science in devising effectual intervention strategies. Plans for dissemination of information that has low magnitude of cultural distance, need to be radically different in nature vis a vis approaches required for popularising scientific ideas that tend to cluster at the farthest end of the scale. In developing countries, the formal system of modern education operates as a strong determinant in shaping the cultural structure of thought prevalent among the citizens. It influences the worldview of even those who have never received any formal schooling and are categorised as ‘illiterate’.

The efficiency of
3,3'-dinitrobenzophenone as a cathode material in a magnesium/zinc based primary
battery is examined. The discharge performance of the cell is investigated
under different parametric variations such as temperature, nature of
electrolyte, current drain and zeolite modification. A 14e reduction seems to
be responsible for the electrochemical reaction causing the reduction of
3,3'-dinitrobenzophenone to the diamino derivative, including the reduction of
carbonyl group.

An attempt is made to examine short term periodicities, if any, in the sunspot activity and rainfall. The daily mean relative sunspot numbers for July-Sep. during 1961-70 and the daily sunspot means for July-Sep. 1889-1938, as well as the rainfall series of Tamil Nadu for July-Sep. during 1961-70 have been analyzed by power spectrum. The study has suggested that the sunspot activity and the rainfall contain a concurrent 30-day periodicity which is highly significant during the southwest monsoon period (July-Sep.) when the sun remains at all times in the northern hemisphere.

Fibromyalgia syndrome (FMS) is a complex chronic condition causing widespread pain and variety of other symptoms. It produces pain in the soft tissues located around joints throughout the body. FMS has unknown etiology and its pathophysiology is not fully understood. However, abnormality in circadian rhythm of hormonal profiles and cytokines has been observed in this disorder. Moreover, there are reports of deficiency of serotonin, melatonin, cortisol and cytokines in FMS patients, which are fully regulated by circadian rhythm. Melatonin, the primary hormone of the pineal gland regulates the body’s circadian rhythm and normally its levels begin to rise in the mid-to-late evening, remain high for most of the night, and then decrease in the early morning. FMS patients have lower melatonin secretion during the hours of darkness than the healthy subjects. This may contribute to impaired sleep at night, fatigue during the day and changed pain perception. Studies have shown blunting of normal diurnal cortisol rhythm, with elevated evening serum cortisol level in patients with FMS. Thus, due to perturbed level of cortisol secretion several symptoms of FMS may occur. Moreover, disturbed cytokine levels have also been reported in FMS patients. Therefore, circadian rhythm can be an important factor in the pathophysiology, diagnosis and treatment of FMS. This article explores the circadian pattern of abnormalities in FMS patients, as this may help in better understanding the role of variation in symptoms of FMS and its possible relationship with circadian variations of melatonin, cortisol, cytokines and serotonin levels.

To evaluate the potential abortifacient activity of the aqueous, alcohol, ethyl acetate and chloroform extracts of P. rubra pod in female albino rats 50, 100 and 200 mg/kg body weight doses of each extract were administered from day 11 to 15 of pregnancy and animals were allowed to go full term. The phytochemical screening revealed the presence of alkaloids, flavonoids, simple phenolics, steroids, tannins and saponins. Clinical toxicity symptoms such as respiratory distress, salivation, weight loss, dull eyes, diarrhea, and change in the appearance of fur as well as mortality were not observed in the animals at any period of the experiment. All the four extracts of P. rubra pods exhibited abortifacient activity (8-100%). The extracts significantly reduced the number of live fetuses, whereas the resorption index and post implantation losses increased significantly. The % of abortion was found to be highest (100%) with 200 mg/kg dose of alcoholic extract of P. rubra pods.

A1,3 type strain is demonstrated directly by the nuclear magnetic resonance studies (1H and 13C NMR) on the N-acetyl derivatives of 2-phenyl-trans-decahydroquinolin-4-ones 5-8. In compounds 5-8 the bulky phenyl group is forced to assume axial orientation due to a severe A1,3 interaction in equatorial position. The ring torsional angles about C(2) –C(3) bond and Karplus constants have been determined using DAERM method. The calculated torsional angles in the N-acetyl derivatives are significantly higher than that in the normal chair conformation and thus confirm the nonchair (twist-boat) conformation of the heterocyclic ring with diaxial orientation of phenyl and alkyl groups in N-acetyl derivatives.

The kinetics of dissociation of maleate and fumarate from the maleato- and fumarato-pen taamminecobait (III) complexes have been investigated in aqueous perchloric acid (0.1 to0.7 mol dm-3) over a temperature range of 60-80°C at an ionic strength of 1.0 mol dm-3 adjusted with sodium perchlorate. Variation of observed pseudo first order rate constants on [acid] suggests operation of two concurrent path with kobs = k1 + k2 [H +], where k1 and k2 are the rate constants for the uncatalysed and acid-catalysed pathways respectively. Under identical conditions, fumaratopentaamminecobalt (III) complex is more reactive than maleatopentaamminecobalt (III) complex. The influence of free carboxylic proton and nitrate ion effect on the rate of substitution reactions have been discussed. Analysis of the rate data corresponding to k2suggests a dissociative mechanism involving the protonated species (protonation on the adjacent carbonyl oxygen and not on the carboxylate oxygen). The solvent isotope effect, kD2O/kH2O for the dissociation process is 2.6, consistent with a mechanism involving a rapid pre-equilibrium protonation step followed by a slow rate-determining dissociation. Mechanisms involving concerted attack by H+ and H2O are excluded.

The effect of oral administration of acephate (360 mg/kg body weight), for 15 days, daily, was investigated on the erythrocytes of male rats. Activities of acetyl cholinesterase and glucose-6-phosphate dehydrogenase decreased, while those of glutathione-s-transferase and glutathione reductase increased. Decreased glutathione content and increased lipid peroxidation suggest that there was increased oxidative stress in the erythrocytes of treated animals. Increased cholesterol/phospholipid ratio in the erythrocyte membranes and morphological changes in RBCs (scanning electron microscopy studies) were observed in acephate treated animals. The results clearly suggest that acephate induced oxidative stress in erythrocytes leads to morphological changes.

The physicochemical characteristics, acidic properties and catalytic activities of the title ternary oxides synthesized by' homogeneous coprecipitation have been studied. The test reactions selected are alkylation of toluene with 1-propanol and 2-propanol and the dehydration of these alcohols. Surface area, porosity and acid strength of these ternary oxides are lower whereas total acid amount values are higher compared to the previously studied TiO2-SiO2-AI2O3 and MoO3-SiO2-AI2O3 catalysts prepared by heterogeneous coprecipitation. Increase in the pH of coprecipitation from 7 to 12 decreases the acid amount whereas increase in calcination temperature enhances the acid strength. Catalytic activity of both ternary oxide catalysts are found to be high for the dehydration reaction and only moderate for the alkylation. In other words, the dehydration of 2-propanol is catalyzed even by the weakest acid sites and that of 1-propanol by weak and strong acid sites and the alkylation of toluene by only strong acid sites. Nearly 92% of the total acid amount of an unused sample as well as its catalytic activities are shown by both ternary oxides subjected to five successive regeneration cycles.

The utilization of usual supply voltage and clock for repetitive state transistors in digital circuits is a fundamental driver for high power utilization. Most significant bit states of the counter stay longer than the least significant bit states and it has some repetitive states. To limit the supply voltage and stop the clock for MSB Flip Flop (FF) transistor, our method uses Control Combinational Logic, Voltage selector and Modified Integrated Clock Gating blocks. The LSB transistor always have a supply voltage of 1.2V and succession of the clock, while MSB transistor gets just 480mV and the clock will be stopped by the this technique. Bring down the supply voltage and quit the clock for redundant states either 0 or 1 in MSB. Meantime supply 1.2V and clock for state changes over from one state to next state. The experimental simulation was done in 45nm CMOS technology using Cadence virtuoso indicates that this asynchronous counter achieves a power savings of 23.57% and the same modified technique when applied to the counters with transmission-gate FF, hybrid-latch FF and sense amplifier FF will have more than 40% power savings and the technique applied in some benchmark circuits will have more than 22% power savings than existing techniques.

Transhumance system of livelihood of the Brokpa pastoral nomads inhabiting in the yak tracts of Arunachal Pradesh with special emphasis on climate change adaptation was assessed in the present study. A representative sample of the 240 Brokpa pastoral nomads from all the yak rearing tracts of Arunachal Pradesh was selected randomly. The Brokpa pastoral nomads mainly depend upon livestock, like yak, yak-cattle hybrid etc, rearing for their livelihood. They perceived that season cycle has been changed in lower and mid altitude. They also perceived that onset of summer is getting started 1-2 month(s) earlier than before and also extended by 2-3 months. Therefore, Brokpa pastoral nomads of Arunachal Pradesh have expanded their migration duration by 2-3 months in searching of congenial environment for their livestock specially yak and yak-cattle hybrid. They adopted 10 coping mechanisms to cope up with negative impact of climate change. Among the coping mechanisms, ‘duration of migration has expanded by 2-3 months’ and ‘change in pasture utilization practice’ were found to be mostly adopted.
