Noise Pollution is the biggest problem faced by all the countries and all of them are investing a huge amount of money as well as time to solve the problem of pollution. Noise to electricity is not only solves one of the greatest problem of noise pollution but also gives the most demand able output which is electricity.

A loudspeaker (or speaker) is a transducer, which converts an electrical signal into sound waves. Since noise is also a form of sound wave or mixture of different kinds of waves, which gets wasted in the environment, so by law of conservation of energy it can be converted into another form of energy i.e. electrical energy, so by using a speaker ...

The standards for transformation and transfection for years have been plasmid transfer by conjugate mating, DNA uptake by competent cells, chemical permeation, electroporation, and detergent and liposomal vectors and viral vectors, of bacterial and eukaryotic cells, respectively. The new standards for genetic modification employing such vectors involve CRISPR which causes directed double-strand DNA breaks and homologous recombination/repair (the latter using endogenous cellular processes). Off target changes can occur, although recent efforts have been made by the developers to avoid such untoward effects.

BioSPLICE, BIOSYNTHETIC PLASMID INTEGRATED CAPTURE ELEMENTS, US Patent 8,628,955 B2, Jan. 14, 2014, was designed to provide a new synthetic to biosynthetic vector which avoided these issues and could be used in vivo as well as in ...

We present in this opportunity a 6 passenger full eVTOL aircraft concept for Urban transportation, with vertical propulsion electrical engines and propellers in under the fuselage arranged configuration with air intake. Also will have engines on the sides of the fuselage for horizontal propulsión.

My company: GRUG GROUP LLC, was founded to supply services in the aviation sector and to develop a variety of future aircraft. We currently are working on several eVTOL flying vehicles concepts. Those are designed with different characteristic and capacities to fit a wide range of the demand that could be in the future.

The projected global market for urban passenger flying vehicles will be of 21 billion US dollars for the year 2035. Other ...

In extreme hot summer, many people, particularly the elderly, can suffer heat-stroke and die. For example, in 2018, there were more than 65,000 global deaths due to extreme heat wave. Therefore, air-conditioning is no longer a luxury but a necessity.
Air conditioners literally save lives and improve quality of life both at home and at work. So why are air conditioners not available everywhere? Present day air conditioners, invented in 1902, face a number of challenges. Firstly, they consume huge amounts of energy; secondly, they cause significant environmental detriment due to the use of chemical refrigerants; and lastly, to cool a desired location, they dissipate large amounts of heat to the environment; creating undesirable heat zones.

Conventional water-based ...

NASA Langley Research Center has developed a novel fine interpolation technique that is useful in signal processing for applications in lidar, sonar, radar and similar modalities. The interpolation technique uses repeating waveforms, Fourier transform reordering, and Richardson-Lucy deconvolution to obtain faster and more accurate results.The prime target application is range finding, but the technique is equally suitable for differential absorption studies, such as determining CO2 concentrations in the atmosphere.

Benefits

Provides an interpolation scheme much faster than those currently in use
Consists of a simple reordering of a Fourier transform array
Can be applied broadly with any repeating waveform, and not confined to PN code and PSK modulation
Compatible with lidar, radar, sonar and similar modalities

Problem:
1) Various e-scooter companies (backed by venture capital) are rolling out their products in the market - the focus is major cities around the globe.
2) None of the companies have so far convincingly addressed the safety concerns related to not providing head protection as part of the actual rental process. And their customers often simply do not carry any head protection (even if it given away for free) with them.
3) The result is a growing number of head injuries. CNET reported on 28 November 2018 that "Injured scooter riders are flooding US emergency rooms. Accident rates could be as high as 1,000 per month.".

Solution:
1) The Böwler Flying Helmet combines a drone and a safety helmet into ...

When disasters happen, we don't have a refrigerator to keep our temperature-sensitive drugs or vials for patients. This box should be packed at optimum temperature in the lab, or factory, and LED or LCD ON the box which works with a battery, show inner box temperature. The outer box is covered with heat reflective nano insulation coat which keep the inner temperature. The outer box is anti-shock. If something happens and the inner box is damaged, the LCD shows that this product should not be used. We can use this box for any material which is temperature ...

This device uses GPS and a terrain/obstacle database to create a predicted flight path. When the predicted flight path detects an approaching CFIT threat, the device changes from a passive flight following mode, gives the pilot an aural warning and a visual threat display. The pilot gets a 3D visual picture of where the predicted flight path will hit the terrain/obstacle. By maneuvering the airplane, the pilot can alter the predicted flight path away from the terrain/obstacle. When the predicted flight path no longer detects a CFIT threat, the system returns to the passive mode.

What makes this system novel is that when a CFIT threat occurs, it shows the pilot a visual picture of the predicted flight path ...

Prior to AC all-magnet motors were used for some four decades then forgotten, perhaps from ferrites of the day too weak to be very practical while today with cobalts they are far stronger and last at 90% full power >>700-years.

A recent 1-Megawatt all-magnet generator was developed to have 'no spark', for security to provide power in with explosives and isolated from external needs, has a 50-year, 100%-Continuous Duty-cycle output guarantee with normal service.

A specific design for the Astrobotic M-1 Lander, became a novel geometry of all-magnet motors for electricity of 2.6kw, 110vdc, 24A, 18cm x 7.6cm in diameter replacing a 542w solar panel for use in space.

An advantage for in-transit being aiming with reactors no fuel, allows lunar night ...

Beddingo sheets are a two-piece fitted sheet simple system - a base and a sheet, which attached together for fast and easy sheet changes.

Once installed, the base will remain around the mattress and never have to be removed. Beddingo sheet then easily attached on and off, with velcro fasteners, for easy changing.

Beddingo sheets have 4 main advantages:
1. No need to ever lift your mattress again!
2. Corners doesn’t pop off, stay secure all night long.
3. All fabrics made from premium quality 100% organic cotton.
4. Takes half the time to change ...
