Dynamic Voltage Frequency Scaling (DVFS) techniques are used to improve energy efficiency of GPUs. Literature survey and thorough analysis of various schemes on DVFS techniques during the last decade are presented in this paper. Detailed analysis of the schemes is included with respect to comparison of various DVFS techniques over the years. To endow with knowledge of various power management techniques that utilize DVFS during the last decade is the main objective of this paper. During the study, we find that DVFS not only work solely but also in coordination with other power optimization techniques like load balancing and task mapping where performance and energy efficiency are affected by varying the platform and benchmark. Thorough analysis of various schemes on DVFS techniques is presented in this paper such that further research in the field of DVFS can be enhanced.

A new circuit technique for 65 nm technology is proposed in this paper for reducing the subthreshold and gate oxide leakage currents in idle and non idle mode of operation for footerless domino circuits. In this technique a p-type and an n-type leakage controlled transistors (LCTs) are introduced between the pull-up and pull-down network and the gate of one is controlled by the source of the other. For any combination of input, one of the LCT will operate near its cut off region and will increase the resistance between supply voltage and ground resulting in reduced leakage current. Furthermore, the leakage current is suppressed at the output inverter circuit by inserting a transistor below the n-type transistor of the inverter offering more resistive path between supply voltage and ground. The proposed technique is applied on benchmark circuits reduction of active power consumption is observed from 10.9% to 44.76% at different temperature variations. For same benchmark circuits, operating at two clock modes and giving low and high inputs at 25℃ and 110℃ temperatures the maximum leakage power saving of 98.9% is achieved when compared to standard footerless domino logic circuits.

The concentrations of twenty five heavy metals adsorbed to fine fraction of particulate matter, PM2.5 (d ≤ 2.5 μm) have been experimentally analysed at a sampling site located at the kerbside along a National Highway in Delhi city, India. The sampling has been carried out for 12-hour using Ecotech Intruments, APM550. The PM2.5 has been collected on PTFE filter papers for the winter season. Later, the filter papers have been analysed for various heavy metal concentrations using ED-XRF. It has been observed that the metals concentrations are in this trend: Si > K > S > Ca = Fe > Zn = Pb > Br. it is observed that Si has high co-relation with Ca, Fe and K, which may be due to crustal origin of all three elements;while S, Br and Pb may be from vehicular exhaust emissions and/or abrasions due to brake and tyre wear. The potential health risks associated with different carcinogenic heavy metals have also been calculated. One of the health risk indicators, the excess cancer risk (ECR), is found to be in the order as As > Cd > Pb > Cr > Ni.

In the present work, Laser induced Breakdown spectroscopy technique is used to investigate the laser induced plasma of PMMA in air. The optical emission of PMMA plasma is found quite intense and dominated by vibrational band of CN molecules （violet band, B^2∑^＋ - X^2∑^＋） at 388.4 nm. The temporal response of the CN band emission is studied and found decay time 22 ns. The low decay time and small laser spot （34 × 32 μm^2） conf＇n-ms good thermal stability of PMMA. To get structural fingerprint of PMMA, Raman spectrum is recorded prior to the exposure to laser. Several sharp Raman peaks have been observed along with a very intense peak at 2,957 cm1 attributed to C-H stretching vibration. Post exposure Raman spectrum is also recorded to analyze the heating effect and re-deposition of ablated material.

Terrestrial plants have two to four times more ATP-binding cassette （ABC） transporter genes than other organisms, including their ancestral microalgae. Recent studies found that plants harboring mutations in these transporters exhibit dramatic phenotypes, many of which are related to developmental processes and functions necessary for life on dry land. These results suggest that ABC transporters multiplied during evolution and assumed novel functions that allowed plants to adapt to terrestrial environmental conditions. Examining the literature on plant ABC transporters from this viewpoint led us to propose that diverse ABC transporters enabled many unique and essential aspects of a terrestrial plant＇s lifestyle, by transporting various compounds across specific membranes of the plant.
