Soap Effect to Your Healthy Skin

Soap is an anionic surfactant used in conjunction with water for washing and cleaning, which historically comes either in solid bars or in the form of a viscous liquid.

Soap consists of sodium or potassium salts of fatty acids and is obtained by reacting common oils or fats with a strong alkaline solution (the base, popularly referred to as lye) in a process known as saponification. The fats are hydrolyzed by the base, yielding alkali salts of fatty acids (crude soap) and glycerol.

soap is a part life everyday, healthy skin dependant on soap product your option. More and more alkalic of soap more and more bad effect on the skin. So, you must care in choice product soap for your skin.

Skin is Protective an anatomical barrier from pathogens and damage between the internal and external environment in bodily defense, Langerhans cells in the skin are part of the adaptive immune system.

Surface skin have acid coating, acid coating is a layer film have the quality acid and protective skin function. Cleanse of skin with soap or detergent can be cause asam coating loss. If acid coating be loss skin have susceptible to infection.

Acidity skin and face normal skin
Acidity normal skin is between 4-6,5 in high feather although varied between be one with other skin. On the a research in India does pH mensuration on the surface skin, 55 brown skin (Indian) comprise 30 male and 25 female in 12-58 years on forehead and wrist, average pH skin on forehead and wrist is 5,51 +- 0,032 and 5,56 +- 0,040 to male, 5,73 +- 0,032 and 5,84 +- 0,28.1 to female. Also find ones way that pH skin not dependant on age. Male skin over acid than female, average grade pH skin on forehead and wrist is same for male in significant while for female pH skin on forehead and wrist different about 5% in significant.

Surface skin affected factor
Be found some disease skin and systematic increase surface skin pH for example eczema, atopik dermatitis, xerosis, dan lamellar ichthyosis. Systematic disease is Diabetes, Cerebrovaskuler, and end-stage. External factor disturb surface skin pH is cleanser for example soap, detergent, moisturizing, topical irritant, and topical antimicrobial.

Solar Powered UAV Under Development

If UAVs starts running on the solar system, then it will save lots of expensive fossil fuel and the add-ons in the form of greenhouse effects. Researchers at the Queensland University of Technology are working on a model of a solar-powered unmanned flight system for round-the-clock surveillance. They have christened their baby as the Green Falcon. This solar UAV aspires not only to save lives but millions of dollars too by using the most up-to-date green technology. Queensland University of Technology is aiming to make the services of this unmanned air vehicle commercially available within 24 months following successful flight tests.

The Green Falcon is outfitted with a next generation warning system complete with remote sensing and visual data capabilities. Both of these facilities enable this UAV to detect bush fires in Australia that have caused huge damage in terms of lives, money and property. Another possibility is monitoring fires. The university’s aerospace avionics engineer Dr Felipe Gonzalez states, “Bush fires in Australia have killed many people and caused millions of dollars in damage. The Green Falcon is a next-generation warning system with remote sensing and visual data capability.”

The best thing about this UAV is it consumes solar energy during the day and stores it in an onboard battery pack. This battery powers the aircraft after dark. It is also fitted with infrared cameras. These cameras will be handy during search operations in locating distressed people and relay the information to emergency services on the ground. Another advantage of this UAV according to Dr. Gonzalez is “Unlike manned aircraft, which have restricted air time, unmanned aerial vehicles could provide 24 hours surveillance and coverage of disaster areas.”

Green Falcon has a wingspan of 2.5m and weighs 4kg (8.8lb) without a payload. This UAV contains 28 advanced highly efficient monocrystalline solar cells. Green Falcon also boasts of a maximum power point tracker, a purpose-built energy management system and a proficient lithium-ion battery. This UAV also requires minimum maintenance cost. It can be hand-launched for easy operation. Operator on the ground can obtain and react to images and videos sent by the plane.

This UAV can also be utilized for coastal scrutiny, atmospheric and weather research and prediction, environmental, forestry, agricultural, and oceanic monitoring and imaging for the media and real-estate industries. Gonzalez shares his opinion, “The Green Falcon is lightweight, it can be hand-launched and costs are low compared with other UAVs available today.”

The design supports improved swarming capabilities compared with other UAVs, says Gonzalez, which will allow the Green Falcon to provide coverage over large areas in as short a time possible, particularly useful in rescue or fire monitoring missions.

The first test flight of the Green Falcon was performed in June. To perform further experiments fund of A $50,000-80,000 ($45,000-75,000) is needed.

Energy Efficient Communications Networks

Reputed companies are always conscious about their brand image and what a great way to build great brand by taking clean and green route! Bell Lab is the division of the Alcatel-Lucent. Currently Alcatel-Lucent is trying to invest in their communications networks to make it 1,000 times more energy efficient. They have launched a five year program known as “Green Touch.” Members affiliated with the Green Touch are AT&T, and China Mobile from industry; MIT and Stanford University from the academic world; and The French National Institute for Research in Computer Science and Control from government. Industrial laboratory members are Bell Labs, the Samsung Advanced Institute of Technology and Freescale Semiconductor. The project has received the nods of ascent from United States Secretary of Energy Steven Chu and the British, French, South Korean and Portuguese governments.

They are going to hold their first meeting in February. The group will chalk-out its 5-year action plan, responsibilities of the members and what role they will play in achieving the overall goal. Their focus will be the telecom field. They want to develop a reference network architecture and the key components in these five years.
Reaching out to make the world greener

Green Touch will depend on the Bell Labs to do required research and provide necessary data to move ahead in achieving its 1,000-fold efficiency improvement in energy field. The laboratory had already accomplished the task of analyzing information and communication (ICT) networks technologies and architecture. After this Bell Labs then applied the Shannon-Hartley Theorem to its findings. In plain terms this theorem represents the maximum possible bandwidth available for broadcasting by adding the value of the signal encoding the data and the value of the noise, or interference.
The Green Touch Vision

The Green Touch Project seeks to accomplish the architecture, specifications and roadmap by 2015. Their aim is to reduce energy utilization of communications networks by a factor of 1,000 for every consumer from current levels. Gee Rittenhouse is the head of research at Alcatel-Lucent (NYSE: ALU) Bell Laboratories. According to him, “It is a really very aggressive schedule. We have five years to demonstrate these technologies.”

Bell Labs wants more and more organizations to join the Green Touch project. They are expecting to grow their tribe in numbers.

Rob Enderle is the principal analyst of the Enderle Group. He expresses his view, “Governments should like this trend a great deal, and I would expect they’ll have no problem getting on board. It may end up simply being a problem of keeping the folks that have to approve announcements down to a manageable level.”

The members of the project are not ruling out the competition also. Enderle envisages, “This may begin a new war, one on cost savings, which will drive a bigger pricing war” It might also launch a battle for dominance of the standards in this area as networking giants like Cisco (Nasdaq: CSCO) get involved. “Cisco is a big enough power in the segment to create standards pretty much on its own,” Enderle said.

But competition is not a bad thing at all. Consumer and companies both might be benefited at the end of the day. Enderle explains, “The result will benefit us all, regardless of whether this consortium or some other consortium or Cisco gets to it first.”

The Pedal A Watt Stationary Bicycle Generator

Today’s twin goals of keeping fit while doing something good for the planet by creating electricity without any pollution come together in a product that has been around for over ten years – The Pedal-A-Watt Stationary Bicycle Generator. Use your bicycle along with the Pedal-A-Watt Stand (it takes 15 seconds to drop your bike in) and create anywhere from 100 to 300 watts depending on how strong you are.

Then, use this energy to power small, household appliances. For example, a home office with a laptop and high efficiency LED lighting can be run for almost three hours on just a 30 minute workout.

The kids can “earn” their TV time by pedaling to create the energy needed to watch their favorite shows. Plus, kids will learn the true meaning of a “watt” and how many watts it takes to power their favorite electronic devices. It gives them a newfound appreciation for the cost of energy in physical terms.

And, the user will be helping to stay fit too. The typical adult will burn somewhere between 300 and 700 calories for each 30 minute workout. A few times a week and the calories expended really add up. Plus, the amount of energy created over time is surprising.

People all over the world have used the Pedal-A-Watt to power all kinds of items such a projectors, radios, lights in remote villages, water pumps, small heaters, chicken coops and hundreds of other unique applications.

The Pedal-A-Watt has been donated to schools across the country to help grade school children learn about alternative energy.

Energy Harvesting "Piezo Tree" Consept

Researchers at the Cornell University have taken inspiration from nature and tried to imitate the swaying of tree branches. So what is the difference between natural swaying of trees and energy-harvesting tree created by Cornell University researchers? The flapping leaves developed in the laboratory generate energy which can be utilized by us. They are christened as the “Piezo-tree.” The synthetic leaves of the “Piezo-tree” are connected to a piezoelectric stem. The whole exercise till now appears to be low-cost, and easily scalable.

The movement of leaves is responsible for generating energy. They convert wind energy into electrical energy. The flapping motion of the leaves causes the instability of the aero-elastic system. The main constituent of the “Piezo-tree” is of Polyvinylidene Fluoride (PVDF) which is a flexible piezoelectric material.

The prototype behaves as a tree facing breeze. The Piezo-tree’s flexible plate and film oscillate just as a flag or leaf might flap in the wind. The flapping motion is generated due to instability of the aero-elastic system. Because the flexible piezoelectric material Polyvinylidene Fluoride (PVDF) can endure unpredictable wind strength. They have attached one edge of PVDF element to a cylinder bluff body and left the other edge free. When the breeze blows and touches this bluff body, it leads to a vortex-shedding. Then the periodic pressure difference forces the piezo-leaf to synchronously bend in the downstream of the air wake. The AC signal is gleaned from the flapping piezo-leaf that is working on a periodic bending model, and the electrical energy is then stored in a capacitor after rectifying it with a full-wave bridge.

However, Cornell University researchers were able to generate only about 100 pW because of the weak piezoelectric strain coefficient of PVDF. When the preliminary Piezo-Leaf Generator’s power level was not sufficient enough it was unable to drive even a common LED. Then, researchers attached a piece of plastic film to the end of the leaf along the direction of air flow. This move paid off. Now it showed around 100 times increase of power in the same condition. Researchers also tried various permutations and combinations. They had conducted a series of experiments. They utilized attachments of various shape, area, density and flexibility of plastic and polymer film. This threw out different results in the level of power.

When researchers were trying out different anatomical structure of their synthetic tree their design optimization studies showed that a particular vertical stalk, horizontal leaf arrangement would increase power output by an order of magnitude. This is a enormous, ten-fold progress over current leaf-stalk arrangements. The “piezo-tree” could be utilized as an efficient and exceptional power producer in a variety of environments. For practical and commercial purposes the researchers anticipate to build plant-like devices with hundreds or thousands of piezo-leaves
