Abstract

By the using of MCML circuits, a 4 GB/s clock non-sequential phase detector circuit is designed in a 0.35μm CMOS technology. The power dissipation of proposed phase detector is much smaller than the conventional complementary pass transistor logic (CPL) phase detector. The implemented MCML phase detector consumes 0.7688nW when operating upto 4GHz clock frequency with 3.3V supply voltage. The conventional CPL phase detector consumes 4.7856nW when operating upto 2GHz clock frequency. The modified phase detector can be used in high speed and low power consumption applications.

Abstract

For manufacturing point of view, to attain a coated paper of best performance, selection or optimization of base paper properties is necessary. Base paper characteristics like roughness, porosity equally contribute as pigment properties. The quality of coated paper is majorly influenced by the properties of base paper. A base paper property defines the final coating structure, its optical efficiency, and the resulting coated paper performance and printability. Final coated paper decides the printability result by its coating Structure, optical efficiency, which is also influence of base paper.

Abstract

Substitution of wheat flours with non-wheat flours has received considerable attention in recent years due to their positive health benefits. The influence of blending (5-25 %) of popped makhana flour and wheat flour on the physico-chemical, textural and sensory qualities of cookie made from popped makhana-wheat flour blend was investigated. The physico-chemical characteristics of cookies were evaluated in terms of proximate composition and energy value. Physical properties were in terms of cookie diameter, thickness, spread ratio, colour and cookie breaking strength (texture). The cookie sensory qualities were evaluated in terms of texture, mouthfeel, taste, colour and overall acceptability. Increase in the popped makhana flour proportion increased the moisture and protein content of the cookies and resulted in a decrease in the fat, ash content, crude fibre, carbohydrates and energy value of the cookie. Breaking strength of the cookies significantly (p<0.05) increased whereas cookie diameter and spread ratio significantly decreased with an increase in popped makhana flour proportion. On the other hand, increase in weight and thickness was observed with increase in proportion of popped makhana flour. The colour value in terms of L*, a* and b* also decreased and increase in colour difference was observed. The sensory quality scores of cookie decreased significantly with increase in popped makhana flour proportion. The results of overall acceptability confirmed that replacing of wheat flour with popped makhana flour up to 25 per cent for cookie baking was fairly acceptable by the sensory panelist.

Abstract

Nature, an interdisciplinary scientific journal, is one of the world's most reputed journals. It has been ranked the world's most cited scientific journal by the Science Edition of 2014 Journal Citation Reports, and is widely regarded as one of the few remaining academic journals that publish original research across a wide range of scientific fields. Academic Ranking of World Universities considers papers specifically published in Nature as a criterion for its world rankings. In 2009, Nature was named as the 'journal of the century' by the Bio-Medical and Life Sciences Division (DBIO) of the Special Libraries Association (SLA), USA. Needless to say, having a paper published in Nature is considered prestigious. The present study aims to show India's output in this journal.

Abstract

Globally, the use of English language has been continuously increasing and English is reported to be the most widely learned second language. In scholarly communication too, English has become the preferred language although it is well known that many scientific terminologies and words are derived from Latin and Greek. It has been reported that 'science reached the end of its Latin when in 2012 International Code of Botanical Nomenclature declared as no longer obligatory that the Linnaean binomial classification, but also the description of candidates for new species, be in Latin'.

Abstract

Trichosanthes dioica R. (Cucurbitaceae), an important perennial herb found throughout the Asia and is figured high in Indian medicine system for its versatile therapeutic and prophylactic properties. To justify its traditional claim, hair growth activity was performed with ethanol and aqueous extracts on wistar albino rats using minoxidil as standard. The extracts were formulated as 5% ointments and formulations were applied topically on the denuded back of rats. Both formulations exhibited prominent hair growth activity as compared to control group (p<0.05) as well as minoxidil treated group. The number of hairs and hair length were also measured which were more significant for formulations. Formulation having 5% aqueous extract found more potent than other groups. The results of this study revealed the presence of strong hair growth potential in the leaves of Trichosanthes dioica R.

Abstract

In this paper we presented two simple designsChebyshev 3-pole microstrip stepped-impedance low-pass filter in L-band (1 GHz) and folded arm microstrip lowpass filter which is widely being implemented in GPS systems, mobile phones and defence telemetry. Various shapes are designed, simulated and frequency is tuned by altering the stub size and its position. According to the shape of the devices these two filters can be implemented. These two filters are designed for 1 GHz cut-off frequency at -3dB with a passband ripples less than 0.1dB and it shows sharp stopband 1 GHz - 4.9 GHz. Effective permittivity of the substrate is 10.8 and height 1.27 mm. The stepped impedance LPF is a traditional filter and folded arm filter is also a stepped impedance LPF but its inductive arm is bent at 90°. Folded arm filter is the miniaturized form of the traditional LPF. The miniaturized LPF gives the same performance as the traditional stepped impedance LPF. The filter is miniaturized by folding its inductive arm at 90° and its dimensions are optimized. Area of folded arm lowpass filter is reduced by 27.9% with respect to the traditional stepped impedance lowpass filter. These LPF filters are designed and simulated on Ansoft-HFSS platform. Its gives the satisfactory results between theoretical and simulated ones.

Abstract

In the recent times, two dimensional layered single crystals attracted huge attention to their tunable mechanical, optical and electronic properties which have potential applications in future nanoelectronics and optoelectronics for large scale integration in low power technology. Phosphorene, the single- or few layer form of black phosphorus, was lately investigated as a two dimension layered material with motivating promising applications in the field of nanoelectronics and optoelectronics. However, there is still a need for developing its fundamental properties, design schemes and growth techniques. In this context, we review about the recent progress in phosphorene studies, primarily on the fabrication process, properties, forthcoming applications and challenges. In this article, the anisotropic properties (electronic, optoelectronic, thermoelectric and mechanical) of phosphorene, due to its puckered structure is also highlighted. The extraordinary properties of phosphorene make it a future material for designing and fabrication of nanodevices, and more fundamental and technological developments can be established in the near future.

Abstract

Errors of measurement arise because our observations are affected by many sources of variability, but our conceptual frameworks necessarily ignore much of this variability. Sources of variability that are not included in our models and descriptions of phenomena are treated as error. A good theory of error supports the development of precise measurements, clearly defined constructs and sound public policy. Narrowly defined constructs that do not generalize much beyond the observed performances do not involve many sources of error, but constructs that generalize observed scores over a broad range of conditions of observation necessarily involve many potential sources of error. We can have narrow constructs with small errors or more broadly defined constructs with larger errors. Some errors that are negligible for individuals can have a substantial impact on estimates of group performance, and therefore, can have serious consequences.

Keywords

Measurement, Errors, Control.

Abstract

Zinc oxide and many other materials have long been used in thermoelectric devices for Waste heat recovery to convert heat into electricity. The performance of these materials depends on the figure-of-merit ZT (=S2σ T/κ), where S is the Seebeck coefficient, σ is the electrical conductivity, κ is the thermal conductivity, and T is the temperature. The study focused on the doping mechanisms of ZnO with Aluminum, and then the thermoelectric properties of ZnO doped with aluminum by spark plasma sintering technique. For Al-doped ZnO, the spark plasma sintering technique used to prepare samples from precursors canceled at various temperatures. I take these samples for study for doping mechanism in different material. For Al, doped ZnO, the spark plasma sintering conditions together with the micro structural evolution and thermoelectric properties of the samples were studied in detail. Moreover, nano composite approaches have been used to study the thermoelectric properties of other material systems such as Zinc oxide and half-Heusler phases. We observed a significant improvement in peak ZT of nano structured n-type HH compound 0.8 to 1.0 respectively. Here we studied only n-type HH compounds. The improvement of figure of merit is mainly due to the reduction of thermal conductivity. This nanostructure approach is applicable to many other thermoelectric materials that are useful for automotive, industrial waste heat recovery, space power generation and many other fields.
