For the future technologies in which the devices and circuits are integrating more, low power consuming devices are needed. Mostly the reduction of power dissipation work is concentrated on switching and leakage current. However, sub threshold current is also a big factor which leads to power consumption especially for memories. In this paper, leakage power of SRAM memory cell is reduced by power gated sleepy stack structure which leads to lesser power dissipation. The power dissipation is reduced to 226 µW with proposed technique compared with power dissipation of conventional 6T SRAM cell which had 740 µW. With lesser power dissipation the circuit can have more battery backup and lesser heat emission

Gunshot injuries involving the head and neck confer a high potential for profound morbidity and mortality rates by damaging vital neurovascular structures, including the central nervous system, carotid arteries, and jugular veins. The main manners of firearm-related death comprise homicide, suicide, and accidental events, the rates of which largely vary depending on region and country. Although a bullet is commonly thought to travel through the body in a straight line, a few patients with head and neck gunshot injuries who survived without lethal organ damage thanks to a nonlinear bullet trajectory have been reported. However, there is no report of a patient who survived a gunshot wound transversely penetrating the entire neck across its deep structures. India’s rates of violence vary greatly and in a majority of firearm related injuries illegal, unlicensed weapons are used. As in 2006, India was home to roughly 40 million civilian firearms, out of an estimated 650 million civilian owned guns then believed to exist worldwide. But only 6.3 million (just over 15%) are licensed. The unpredictable nature of the bullet also emphasizes the importance of projecting the missile trajectory. A missile trajectory-tracing software program could be an important tool in the diagnosis and management of patients with bullet injuries.

The need to protect our environment by eliminating plastic waste as much as possible and by recycling waste from agricultural residue, has led us to formulate composites based on polyethylene terephthalate (PET) loaded with powder from the cocoa shell. The cocoa hulls were prior treated with organosolv process to improve the fiber-matrix interaction. This research is aimed at manufacturing composite wall tiles from recycled PET reinforced with cocoa hull powder (CCP). The composites were manufactured by the melt-mixing method followed by compression molding. The mechanical, physico-chemical properties and the stability to environmental conditions were evaluated. The results showed that the incorporation of cocoa powder at a content of 20-30% in the matrix consisting of PET gave rise to a composite material with good physico-mechanical and chemical properties suitable for use in several sectors. In the construction industry, in particular as wall covering as a replacement for tiles, these x from an economic point of view cost less and compared to clays which consumes enormous amount of energy for the elaboration of ceramics. The study showed that the optimum powder weight proportion for the optimal properties of the composite were achieved at 30% powder weight proportion. The maximum tensile strength of 60.3 MPa, flexural strength of 19.5 MPa, impact strength of 10.3 MPa and water absorption 1.34% were obtained. Water absorption of the tiles increased with the cocoa powder weight. Compare to the ceramic tile this value of water absorption test is in range and show that this composite tile is suitable for use as bathroom tile.

The novel transition metal ion complexes were synthesized by refluxing the ethanolic solutions of metal acetates with Schiff base in 1:2 ratios. The structure and characterization of synthesized complexes of Mn (II), Co (II), Ni (II), Cu (II) and Zn (II) with Schiff base (E)-2-((7H-purin-6-ylimino)methyl)phenol were elucidated by using 1H NMR, FT-IR and UV-Visible spectroscopic techniques. The synthesized compounds were also been screened against gram positive and gram-negative bacteria. The novel compounds were further carried out for the study of magnetic susceptibility.

A film of electrically active poly(3-(9H-carbazol-9-yl)propanenitrile) was prepared on platinum (Pt) electrode surface by oxidative electro-polymerization of 3-(9H-carbazol-9-yl)propanenitrile monomer. The polymerization reaction was performed in a reaction medium containing monomer, and 0.1 M tetrabutylammonium tetrafluoroborate (TBABF4 ) mixture in acetonitrile (ACN) using repeated cycling at a scanning rate of 250 mV. Electrochemical polymerization of carbazole (Cz) and 3-(9H-carbazol-9-yl)propanenitrile (25 mM) were studied with cyclic voltammetry on both Pt and ITO electrodes. The structure of the poly(3-(9H-carbazol-9-yl)propanenitrile) was elucidated by nuclear magnetic resonance (1H and 13C NMR) and Fourier transform infrared (FTIR) spectroscopy. The weight average molecular weight (Mw) of the electrochemically synthesized poly(3-(9H-carbazol-9-yl)propanenitrile) was determined using gel permeation chromatography (GPC), where it was found that the Mw of the polymer is equal to 37900 g/mol. The polymer was characterized using dry conductivity measurement, scanning electron microscopy (SEM) and UV-Vis spectroscopy, while the spectro-electrochemical studies indicated that poly(3-(9H-carbazol-9-yl)propanenitrile) films revealed a green color in the oxidized state and a high transmittance in the neutral state. Moreover the poly(3-(9H-carbazol-9-yl)propanenitrile) film is soluble in common organic solvents, like DMSO, THF, NMP and DMAC. The conductivity of poly(3-(9H-carbazol-9-yl)propanenitrile) was found to be 1.62x10-4 S/cm.

In this present work, a prednisolone ion selective electrode (PRED-ISE) has been developed. The electrode shows linear response towards prednisolone in the range 3.0×10−6 – 8.6×10−3 M with a detection limit of 2.5×10−6. PRED-ISE was used as an indicator electrode for the potentiometric titration of different concentrations of standard prednisolone against standardized sodium tetraphenyl borate solution and in tablets. The electrode manifests advantages of low resistance, fast response and, most importantly, good selective relativity to a variety of other cations.

Recycling of rubber waste materials in order to convert these to usable products is one of the main challenges in the rubber industry. Reclaiming of rubber waste and blending it with virgin rubber have increased during the past due to the growing concern on the environment and increase in the prices of synthetic rubbers. Hence, the aim of this study is to partially replace virgin nitrile rubber (NBR) with reclaimed compounded NBR latex waste to develop new rubber blends suitable for special applications. In this study, physico-mechanical properties, ageing performance and swelling behaviour of virgin NBR / reclaimed NBR blend vulcanizates were evaluated and compared with those of the control vulcanizate produced solely with virgin NBR. Results showed that replacement of 50% virgin NBR with reclaimed NBR retained 71-86% of tensile strength, elongation at break and resilience. Hardness and modulus of this blend vulcanizate increased by less than 18%, whereas abrasion volume loss and compression set increased by 27%. Ageing resistance is similar to that of the control vulcanizate. Interestingly, resistance to swelling in toluene and ASTM oil No.3 increased by 14% and 32%, respectively. Hence, the 50:50 virgin NBR / reclaimed NBR vulcanizate would be suitable for oil resistant applications.

Calcium molybdates (undoped and carbon-doped) have been used as a photocatalyst for the degradation of malachite green. These have been characterized by different techniques such as FE-SEM, EDX and XRD. The progress of the reaction has been monitored spectrophotometrically. Different rate affecting parameters like pH, concentration of dye, amount of semiconductor and light intensity have been studied and their optimum values obtained are pH 9.7, concentration of malachite green as 5.00 × 10-4 M, 0.12 g of CaMoO4 and light intensity as 50.0 mWcm–2. A tentative mechanism for the photocatalytic degradation of dye has been proposed, where hydroxyl radical has been observed as an active oxidizing species.
