Fresh skin-care tips

Select fresh, in nature grown fruit and vegetables for the highest benefits. Avoid making more than you have need for a single application. Clean and sanitize all countertops and combination utensils ahead of making any of the recipes. First clean all fruit and vegetables before using as ingredients. Take all ingredients out of the fridge for up to an hour before integration. Don't let fruit acquire any space heater than room temperature.

Fresh fruit and vegetables are particularly high in acids. If you apply anything to your skin and come across a burning sensation, take out immediately and apply cool water. If you are in the care of a dermatologist and on acne medications, please consult with your physician first.

Butter chicken

Butter chicken or murgh makhani is an Indian dish accepted in countries all over the world that have a tradition of Indian restaurants. While the dish's general recipe is well known, the actual flavour can differ from restaurant to restaurant even within Delhi. Butter chicken is usually served with naan, roti, parathas or steamed rice.

It is a dish prepared by marinating a chicken overnight in a yoghurt and spice mixture usually together with garam masala, ginger, lemon or lime, pepper, coriander, cumin, turmeric, chilli, methi and garlic. It is in various ways like to chicken tikka masala. The chicken is then roasted or dry as a bone.

Sound measurement

The decibel (dB) is a logarithmic part of measurement that expresses the magnitude of a physical quantity (usually power) qualified to a specified or implied reference level. Its logarithmic natural history allows very large or very small ratios to be represented by a convenient number, in a related manner to scientific notation. Since it expresses a ratio of two quantities, it is a dimensionless unit. The decibel is useful for a extensive variety of measurements in acoustics, physics, electronics and other disciplines because it linearizes a physical value -- e.g. light intensity or level of noise -- in which exponential changes of magnitude are perceived by humans as being more or less linearly related.

The decibel is not a SI unit. In April 2003, the International Committee for Weights and Measures (CIPM) measured a recommendation for its inclusion in the SI system and decided not to adopt that recommendation. Subsequent the SI convention, the d is lowercase, as it represents the SI prefix deci-, and the B is capitalized, as it is an abbreviation of a name-derived unit, the bel.

SOFAR channel in sound

When sound spreads out evenly in each and every one directions, the intensity drops in proportion to the inverse square of the distance. However, in the ocean there is a layer also called the 'deep sound channel' or SOFAR channel which can imprison sound waves at a particular depth, allowing them to travel much further. In the SOFAR channel, the speed of sound is lesser than that in the layers above and below. Just as light waves will refract towards a section of higher index, sound waves will refract towards a region where their speed is reduced. The result is that sound gets small in the layer, much the way light can be confined in a sheet of glass or optical fiber.

A similar consequence occurs in the atmosphere. Project Mogul successfully used this consequence to detect a nuclear explosion at a considerable distance.
