South Africa has a backlog of affordable housing for its
growing population. An in-depth review of all the
alternative building materials currently available on the
market and available skilled labour needs to be
undertaken.
Due to the lack of skills to build with alternative materials
such as wood or panel boards, a high demand remains for
houses built with conventional bricks and mortar. Such
buildings are perceived to be reliable and strong, but costly
and take more time to construct. Building with bricks and
mortar requires a strong, skilled labourer as it is strenuous
work laying on average 500 – 600 bricks per day. This
together with the declining artisanship in the building
industry is worrying as shown by Doku (2009).

Equipotential lines of each type of electrode are
illustrated to find particles movement in electric field due
to a high voltage electrodes. Any significant variation in
shape of potential lines in different conductivity of
different liquids should be considered and theoretical
assumptions with experimental data will help to analyze
the results.

Polyphenols are one of the most important and certainly
the most numerous among the groups of phytochemicals
present in the plant kingdom.
Currently, over 8000 phenolic structures have been
identified, of which more than 4000 belonging to the class
of flavonoids, and several hundred occur in edible plants.
However, it is thought that the total content of
polyphenols in plants is underestimated as many of the
phenolic compounds present in fruits, vegetables and
derivatives have not yet been identified, escaping the
methods and techniques of analysis used, and the
composition in polyphenols (Fig. 1) for most fruits and
some varieties of cereals is not yet known.

Enzymes are proteins that are involved in most
biochemical reactions in organisms. The aim of this work
is to design a program capable of rapid and accurate design
of new drugs based on enzyme inhibitors. An inhibitor is a
molecule that binds to an enzyme more strongly than its
substrate and therefore prevents the enzymatic reaction of
the substrate.

we can realize that there are still
some errors about real amount of these new and important
cosmological parameters. Therefore, with using a
combination of x ray’s signals effect and Sunyaev-
Zel’dovich (SZ) we use a large, galaxy cluster dynamically

before the overall accuracy of x-ray temperature
measurements are marginalized.

The problem states that, when dropping a metal ball on a
rubber membrane stretched over a plastic cup, a sound can
be heard therefore to find the origin of this sound and
explore how its characteristics depend on relevant
parameters some experiments are done. As the experiment
represents, dropping a metal ball on a membrane with a
specific elasticity, causes it starts going up and down on
membrane and the speed of the movement will slowly
starts to decrease and after a while, the ball will stop on the
membrane.

Have you ever thought which properties in Caoutchouc
have effect on its usage?
By studying and examining the physical and chemical
properties of Caoutchouc, we found rubber is one of the
most essential materials in it. Due to its excellent elasticity,
rubber is used in the manufacture of a different products
including hospital supplies, home appliances and toys.

The aim of this project is to increase the sensitivity of
people by supporting the information taught audibly in
school with visuals and animations and observing the
effects of global warming on the individual. Thanks to this
game, the person will be able to have fun while learning
about the threat waiting for themself and the world, and
they will be able to comprehend the negative effects of
global warming more effectively by directly observing the
events that can be done unconsciously and invisible to the
eye every day.

Most stroke patients develop significant disorders such as
weakness and spasticity that have a severe effect on their
daily activities. The ability to perform Daily Life Activities
(DLA) is highly dependent on hand function, and those
who suffer from hand injuries are less able to perform DLA
and thus reduce their quality of life. In severely ill patients,
the injured hand often has difficulty along the fingers and
no marked improvement over time, which makes restoring
hand function one of the biggest challenges in stroke
rehabilitation. Rehabilitation of finger function after stroke
has changed significantly in recent decades.

Building a package to rescue eggs

Egg is a spherical shape material with a thin and
vulnerable crust. Thus, it must be carried in such a safe
boxes during loading to reduce the risk of being cracked in
potential falls. This will economically help both producers
and sellers. The height of trucks is usually between 2 to 2.5
meters which makes it necessary to save the eggs when it
falls (Fig. 1). As seen in figure (2) the egg has a spherical
structure . Egg contains different layers and parts shown in
figure (2). The layers and components of the egg are:
eggshell, air cell, internal and external membrane, thin and
thick egg white (albumen), germinal disk, vitellina
membrane, chalaza, yolk covered with a soft egg shell
(crust) .

Today, the use of unmanned aerial vehicles has increased,
so the areas of use of unmanned aerial vehicles have also
varied. One of these areas is national defense. In the
developed project, a helicopter was designed that can be
used in military activities such as field scanning, target
detection and target destruction by making helicopters
normally controlled by a human autonomous. Türkiye’s
national and original vehicles Alpin and TUSAŞ T-629 can
be given as examples of existing systems. Alpin is an
autonomous helicopter capable of carrying payloads to
target detection, surveillance and military areas. The T-629
is a remotely controlled heavy class attack helicopter. The
feature that distinguishes the unmanned aerial vehicle
designed in the project from these vehicles is that it can
autonomously attack the determined target by performing
area scanning and target detection.

Short length wire as an electrical fuse
Maral Hasheminasab, Mahan Fallahpour
Journal Vol 7, No 1, 2023, (P 57-60)
A fuse is an electrical safety device that operates to
provide overcurrent protection of an electrical circuit.
There are a myriad of different fuse designs which have
specific current and voltage ratings, breaking capacity, and
response times, depending on the application. The time and
current operating characteristics of fuses are chosen to
provide adequate protection without needless interruption.
An important characteristic of a fuse in our work is the
rated current, which is the maximum current that the fuse
can continuously conduct without breaking and
interrupting the circuit.

Recently, allergic disorders have become a prevalent global epidemic affecting millions of people who experience asthma, allergies, and medication hypersensitivities. Medicinal plants such as Lamiaceae, commonly known as mint, are proving to be much more effective in treating the problem as they contain natural anti-allergenic compounds that act as anti-inflammatory agents to reduce and prevent cascading allergic reactions. This research paper will demonstrate how this plant’s properties work, medicinal uses, and provide up-to-date research about the phytoconstituents from the Lamiaceae family and anti-allergenic activity.
