Nowadays desertification is no longer a purely ecological and environmental problem, but also an economic and social problem, which brings poverty and social instability to human beings. For those threatened by desertification, it means that they will lose their most basic subsistence -- a lack of food. Accompanying flowerpots are designed to grow crops and improve plant survival in desert areas. On the basis of preventing wind and fixing sand, increase economic income to improve living environment for people in desertification areas.

Elinfect is designed to force the vaccine syringe to become disposable so as to completely eliminate the infection caused by repeated use of the syringe. Therefore, two protrusions are added to the bottom of the syringe. When the syringe is pushed to the bottom, the protrusions on both sides limit the extraction of the piston, making the syringe unusable.

More details on how it works look at the second ...

Capsule Vaccine is a simple, disposable vaccine syringe designed initially for the people of Africa. The biggest feature of this vaccine syringe is that it is simple and convenient to operate. Users can make their own injections, which no longer require a large number of professional medical staff to participate, and can effectively save human resources. The disposable and safe syringe also can reduce the risk of medical infection.This vaccine syringe is convenient and hygienic. The location and population are not limited, which will help to improve the prevalence of vaccines and medical conditions in depressed areas such as ...

A Levitated Annular Rotor System (LARS) is proposed to power and propel ultra-heavy vertical lift air vehicles in commercial and military markets. LARS is an invention derived from a conceptual redesign of the helicopter made possible by advancements in electromagnetic motor and energy storage/transport technology. It exploits advances across multiple fields of physics to include electromagnetism and high temperature superconductivity. LARS research aligns with NASA's roadmap for vertical lift technology and Urban Air Mobility.

LARS uses a scalable electromagnetic tip drive design that imparts mechanical torque to a rotor blade assembly within the confined space of the system annulus. The rotating blade assembly is magnetically suspended to minimize frictional energy loss. Comparatively, LARS’ integrates the disparate functions of a helicopter’s ...

Competitive sports are a large part of today’s society. Many players of all ages are at risk of injury due to the pressure of wanting to win and doing well for fans. The excitement of winning, the promise of money and a supportive fan base are great motivators at the professional level, and may cause players to be over-aggressive during game play. They forget about the risks of impact and possibility of concussion and serious injury.

The Energy Absorbing Helmet outer shell is a recently patented technology that presents a breakthrough in safety equipment technology for sports participants who are required to wear a protective helmet during play.

The patented Energy Absorbing Helmet outer shell absorbs and reduces the amount ...

An Outline Mitigating the Effects of Economic Competition on Homeless Mothers

Abstract:
The “Maternal Cooperative” is an effort to better support high risk single homeless mothers and infants in the first few years of bonding and development. This effort is based on creating a new understanding of the origins and adverse effects of individual level economic competition that undermines the general stability of these particular mothers. With this understanding we move to develop a short-term solution that fully supports these mothers and infants during this very critical financial and infant bonding phase.

Premise:
‘Economic Competition’ is the competition for money and resources. In this context we focus on the competition over limited funds and resources on an individual ...

A green means of generating electricity from the pitter patter of falling rain drops and sunshine is described here. A falling rain drop strikes at least one piezoelectric element (coated with multi-layer photovoltaic flexible thin films) of a micro-grid array comprised of many piezoelectric elements. The rain drop imparts its momentum from falling to the struck coated piezoelectric element(s) through its flexible coating converting the rain drop's kinetic energy to electricity. When a piezoelectric crystal is squeezed, deformed, compressed, bent, or struck, it generates electricity via the piezoelectric effect. The piezoelectric element can be a crystal, a ceramic, PZT, a plate, a wafer, scintered crystal mixture multi-layer sandwich, a stack, or a film. Each element is coated on top ...

I have been reading and hearing that the United States is very short on hospital rooms where people infected with this new virus can be isolated to prevent the spreading .

I think I have a very simple solution that can be produced inexpensively, that could turn large open areas into a great many isolation rooms.

I propose making small clear vinyl rooms supported by a pipe structure with an isolated and filtered air supply.

The room would have an airlock setup to help contain any contaminate and it could also serve as a decontamination chamber for people entering or leaving, by providing a shower and a drain. The drain could be simplified by using a wet/dry vac with improved ...

One hand replacing two-hands to perform dual fastener fastening or loosening, the “1 hand DUAL FASTENER MANIPULATION DEVICE" can be used to manipulate two fasteners with the same axis of rotation and to manipulate the fasteners of the same axis of rotation separated by the intermediate material, and the spacing distance can be freely adjusted according to the size of the separated object.

In order to successfully join the two fasteners together, one of the fasteners must be rotated in the first direction and the other fastener must be prevented from rotating or rotating in the second direction at the same time. Typically, the process is accomplished using two separate wrenches or other fastener engagement tools, where one or ...

The cost of hospital ventilators has become cost prohibitive during our present Corona virus epIdemiic as hospitals, states, and countries compete to buy them from the limited supply available in todays’s market place. A safe emergency replacement for ventilators is here suggested. A compressor and accumulator feeds pressurized filtered oxygen or air to a multi electro-pneumatic valve array. A computer controller controls the variable sized opening of each valve controlling each valve’s own variable volume, pressure, and flow rate of oxygen. Oxygen is driven through an ultraviolet sterilizer then distributing the oxygen to many patient masks. An electro-pneumatic valve, as distinguished from, but very similar to, an electro-fluidic valve, can not only turn on the flow of a gas, ...
