This article highlights the key observation of various studies conducted in Indian scenario. In India, the major sources of volatile organic compounds (VOCs) are vehicle exhaust. Other sources include emissions from diesel internal combustion engines, oceanic emission and evaporative emissions. Various aspects of VOCs are studied in detail by various authors in the Indian context. VOC sampling ...

It is unfortunate that the methods used to control dental operative pain may themselves produce distress. It should be the aim of all caring practitioner to reduce injection sensation to minimum so as to alleviate the apprehension and fear from the patient’s mind. The fear of needle prick is a bigger reason of concern and the major cause of avoidance of dental treatment despite the detrimental ...

Gaur egun hizkuntzak irakatsi zein ikasteko hainbat tresna informatiko dauzkagu merkatuan. Euskararen kasuan ere hainbat bide jorratu dira dagoeneko. Izan ere, hizkuntzen irakaskuntzaren arloan aukera asko ematen ditu informatikak. Batzuk hizkuntza bat ikasteko metodo edota osagarri gisa aurkezten dira. Beste batzuk, nahiz eta hizkuntza bat irakasteko izenburupean ez saldu, erabilgarri gerta da...

We discuss higher-dimensional gravitational instantons by studying appropriate self-duality equations for the spin connection. In seven and in eight dimensions, the corresponding spaces admit a covariantly constant spinor and, consequently, have holonomies in G 2 and Spin(7), respectively. We find a non-compact solution to the self-duality equations in eight dimensions in which the self-dual sp...
