Abstract

Tulsi has got the great medicinal value. Studies have also shown Tulsi to be effective for diabetes, by reducing blood glucose levels. The same study showed significant reduction in total cholesterol levels with Tulsi. Another study showed that Tulsi's beneficial effect on blood glucose levels is due to its antioxidant properties. The Rama Tulsi is the effective remedy for the severe acute Respiratory Syndrome. Juice of its leaves gives relief in cold, fever, bronchitis and cough. Tulsi oil is also used as the ear drop. Tulsi helps in curing malaria. It is very effective against indigestion, headache, hysteria, insomnia and cholera. The fresh leaves of Tulsi are taken by the millions of people every day. For over the centuries Tulsi (the queen of herbs) has been known for its remarkable healing properties. Modern scientific research offers impressive evidence that Tulsi reduces stress, enhances stamina, relieves inflammation, lowers cholesterol, eliminates toxins, protects against radiation, prevents gastric ulcers, lowers fevers, improves digestion and provides a rich supply of antioxidants and other nutrients. Tulsi is especially effective in supporting the heart, blood vessels, liver and lungs and also regulates blood pressure and blood sugar. Recent studies suggest that Tulsi may be a COX-2 inhibitor, like many modern painkillers, due to its high concentration of eugenol (1-hydroxy-2- methoxy-4-allylbenzene). Tulsi also shows some promise for protection from poisoning and cataracts. The oil extracted from the Karpoora Tulsi is mostly used in the herbal toiletry. Its oil is also used against the insects and bacteria. Tulsi can not only keep the dreaded Swine flu or H1N1 flu at bay but also help in fast recovery of an afflicted person, Ayurvedic practitioners claim. "The anti-flu property of Tulsi has been discovered by medical experts across the world quite recently. Tulsi improves the body's overall defence mechanism including its ability to fight viral diseases.

Abstract

Ginger is a perennial herb, with underground branching stems (rhizomes) which are swollen and tough. The leaves and rhizomes of ginger have a characteristic fragrance when cut or bruised. Rhizomes are dug out after the leafy parts are dried. Ginger, the underground stem, or rhizome, of the plant Zingiber officinale has been used as a medicine in Asian, Indian, and Arabic herbal traditions since ancient times. Ginger is considered an herbal remedy in many cultures. Over the years, it has been used to reduce inflammation, help with digestion, improve cardiovascular health and even historically to ward off diseases like the plague. The rhizome can be sliced, chopped, minced or served fresh but will always carry the trademark "heat" that has made it a medicinal mystery. Historically, people used ginger to fight disease and cure a fever since people would sweat when they would eat the ischolar_main. Although that helps, since it gets the metabolism racing and warms the body, we now realize that ginger offers additional medicinal benefits. Consumption of ginger helps with blood circulation and has antiinflammatory qualities that ease arthritis and other body aches and pains. It increases the body's production of saliva and other digestive fluids, which relieves an upset stomach and supports healthy digestion. Speeding up digestion helps clean the kidneys and bowels to remove toxins from the body. It also helps ease morning sickness, nausea and motion sickness. Ginger is said to improve digestion and has been known to pep up the appetite, promote saliva production, combat dyspepsia and relieve flatulent colic. It is also thought to be helpful for stomach cramps, alcoholic gastritis and hangover. The shogaol content in Ginger increases the activity of the digestive tract and is particularly helpful in digesting rich, fatty foods. Ginger has been used to cleanse the body of toxins through the skin by stimulating and increasing perspiration and has also been useful in breaking fevers. It is slightly diuretic and further cleanses the body by strengthening kidney function and increasing kidney filtration.

Abstract

In VLSI technology conventional CMOS transistors are continuously scaling down to obtain faster speed of devices and very large scale integrated circuits. But the main drawbacks of CMOS scaling are high leakage current and heavy channel doping. So using CMOS SRAM beyond 45nm cell stability and controlling leakage current are becoming difficult in today's fast low power applications. FinFET may be an alternative of conventional CMOS transistor. In this paper independent double -gate FINFET structure based SRAM 6-Tcell has been proposed to controlling leakage current and improving SRAM cell stability. By adjusting threshold voltage (V_t) without affecting cell ratio we can reduce leakage current so that power during off state of transistor. In conventional CMOS due to heavy channel doping carrier mobilities are reduced which also increases process variations. In independent double gate FINFET technology, two separate gates are used. Threshold voltage of one gate can be altered by varying the voltage at the other gate. In this technology nearly intrinsic channel is used so carrier mobilities will be higher which results in higher speed of devices. Using the thin silicon fin, ratio of I_ON/I_OFF can also be increased. Due to vertical gate, there will no overlapping between source-gate and drain-gate so depletion and junction capacitances will be effectively eliminated. Wiring delay and bitline capacitance of SRAM will also be reduced.

Abstract

In this paper, the switching performance of SODEL(silicon on depletion layer) CMOS is investigated with a view to realizing high speed and low power CMOS applications. Due to smaller parasitic capacitance , the propagation delay time in SODEL CMOS has been improved by up to 25% compared to that of conventional CMOS in 5 stacked NFET inverters at the same Vdd . Also, power-delay product is better by 30% in SODEL CMOS. Latch-up immunity for alpha particle irradiation in SODEL is found to be better than conventional CMOS. So SODEL CMOS device's circuit technology is expected to provide a better solution for low power system-on-chip applications.
