The invention addresses the problems of food and beverage preservation within minutes of time, which means in a situation where cooling beverages or food product is needed quickly, this product will be very useful. The basic idea of the invention is a very small or hand refrigerator that can instantly cool beverages or food products within a matter of minutes. This is done by using conduction heat exchange instead of convection for faster heat transfer between the coils and the cooling product.

Instant cooling hand refrigerator is a very small refrigerator intended for home and field use that can cool beverages and food products under a minute for preservation or satisfaction. This means there is a demand for fast ...

We have combined all aspects of small space, low energy usage, effective operation, minimum consumables and working in microgravity for designing our new system and inspired by human digestive system to design our “Space Waste Digester.” As human digestive system is not depending on gravity and works based on peristalsis and valves and is a perfect system to design a system for handling waste in space. We have used this concept and designed our “Space Waste Digester” which is combination of trash receptacle and feed mechanism and will work seamlessly between the astronaut and reactor. Our system has been designed for microgravity condition and it will work much better and with less energy in this condition. We have used ...

The air conditioning of spaces has become a need of the human being to have a better quality of life, it is common for many families to have equipment to cool the air in their homes in the spring and summer seasons; In hospitals it is important to have air cooling systems for the hygiene conditions that are required, as well as to maintain comfort in public places such as cinemas and restaurants. Particularly in the geographical areas where there is a warm climate, air conditioning equipment is very necessary to counteract the high temperatures. Our team has identified certain problems that still exist regarding conventional air conditioning equipment:

1.- There is a part of the population that cannot ...

1) As already described in 2017 and 2018 entry a body sliding on an inclined plane can be supported by a thread or support perfectly parallel to the horizontal.The weight of a body that is unsupported even at the position of rest by this mechanism is maximum for a plane of inclination 45°as explained mathematically in preprint manuscript doi:10.5281/zenodo.439108 causing compression of spacetime below and expansion of space time above the supporting surface.Here technical modification is made to support the body by a perfectly horizontal thread or support on a plane of increased inclination by way of pressure by an elastic recoil force.

2) The modification has weight of body sliding on inclined plane IP1 and IP2 of lightweight ...

Unfortunately, there are many airplane crashes in the world every year.

From its inception, the main goal of aviation is flight safety and preservation of passenger life. I decided to connect my life with aviation, that’s why I became a cadet of Belarusian State Academy of Aviation, and I want to make the contribution to the development of this industry.

Everyone knows that the main value in life – is life itself. For this reason, I decided to connect my proposal with the safety of flights.

The subject of this project is a bracelet, which is put on the passenger's hand during check-in and removed at the end of the flight. To prevent unforeseen situations the bracelet is fastened ...

The problem of the increase of greenhouse gases in the atmosphere is one of the topics discussed almost daily because the effects on the climate are of daily discussion. It is time to move on to remedies. In practice, remedying the problem of excess CO2 with recapture, using devices installed directly in new-generation cars. If my idea comes to practical implementation, hundreds of millions of electric cars will take over CO2 recapture in the near future. The car will turn from pollution to cleanliness of the atmosphere. The direct capture technologies from the atmosphere are almost mature and in my project they must be distributed to the cars to act on a large scale. Once the task of CO2 ...

Problem statement:
Detection and calculation of malaria parasitemia in human blood smear

Introduction:
Malaria represents a serious public health problem for humans and animals worldwide. Malaria is endemic in more than 100 countries while the majority of the cases occurs in tropic countries. Estimation of parasitemia (in stained blood smears) is an important parameter in malaria diagnosis and malaria research; however it is being perform manually since binging, which is a time consuming method. In contrast this study proposes a Python (Open CV) based image processing tool for easy, user friendly, accurate and cost effective calculation of parasitemia. During this process, initially the malaria positive blood smear image was acquired and a Python Code for Image Processing was developed ...

There are many factors that affect agriculture but the physical factor is the critical matter. Physical factors affecting agriculture are (i) climate (ii) soil and (iii) topography. Meaning temperature, the growing season, altitude, rainfall and wind are the most critical part of a good farming output and most plants are very selective on those factors preference for growing. Even if the land fulfills all the requirements, the output of crops depends upon the space of the land which the farming land fulfills factors like climate which is suitable for the crop.

This project is about solving the space problem in farming land in micro-farming and medium farming areas. This is done by roller farming as seen in the figure. ...

In this current world where technology is growing up day by day which is gradually increasing the usage of precious and expensive things in day to day life for making works handier, the need for security is also hyped in all areas. On the other hand as a human being, we always want to get maximum possible results with less effort and expense. We know well that in the 21st century biometrics is a very effective way of security authentication, but again using the physical biometrics sensors for this purpose makes it a lot more expensive as well as a bit complicated for a common man to afford and use.

When thought variedly for the solution to this problem ...
