coprophagous... Actually it is just kidding,
check yourself with the coprophagous

However, we do use bio solid in growing crops,
as mentioned previously
to have a sustainable agriculture,
using as much natural resource as possibly.
Which means reducing the use of laboratory chemicals.

In deed, did anyone think about where the bio solid drained to after you went to washroom previously?
Quite a tricky question, in everyone ones mind this kind of dirty job would be better far away from where we live and some how deposited to sea probably,
Or even, have no intention of think about where it goes,

First of all, to go through the topic,
we should have the traditional view removed,
bio solid, which are mainly our waste
the feces of ours,
simply there are the
indigested material from the alimentary canal
such as the cellulose
dead cells or living cells from the epidermis of the alimentary canal
so do the bacteria E.coli ( and others)
bile salt and mucus

for it pungent smell it is brought by the H2S and several of organic compounds

does feces still sound disgusting to you when describing with chemicals

Discuss on how bio solid helps in the crops agriculture

since biosolid is consist of undigested food, even in large quantity toxic compounds are rear,

From the chat, the % of hazardous substance is negligible
moreover under a systematic and dedicated procedure of sanitized and fermentation of sewage

from the diagram, we can see that there is an return of fermentation process so to kill most of the bacterias by denaturing their proteins, then it was packed in to package sold to the companies to process their usage of the biosolid

in deed, biosolid has been used successfully in forestry
one of the biggest pro,
it is able to yield more wood than not using the biosolid.
which indicated that biosolid is a favorable fertilizer to crops

there are more pros
such as it is one of the most natural and able to collect easily.
there is a design of the toilet down below which divert the human waste and easy to collect, only in the country side( no one expect such design appear in the urban.)

the solid waste would be go for the fermentation meanwhile the liquid waste will undergo neutralization and use as fertilizer.

Since in the outdoor plant and lawn, there are bacteria undergo catalysis and form the nitrogen ion for the plant to grow.

It is seem perfect in growing, yet
there are several cons should be reminded
first with the highly nutritional biosolid. it is perfect to cultivate different bacterias and so do coprophagous insect.
there the bacteria may spread several disease

SO once you have decided to use biosolid in planting, please be careful not to cultivate any pathogens or else you might be the one who poison the whole district!

Nowadays, with the developed ecologies of medical surgeries, doctors are allowed to do more precise identification and surgery on you as to cure you.

In the ancient’s era, once a person got an internal respiratory, circulatory or alimentary disease, doctors were not really sure what the acute disease is. And they had only the medicine or potion to cure the disease, doctors observed the exterior symptoms or patients’ description on symptoms. Which shown that the doctor had not truly identify the disorder of the patients and which even with the curing process, the patients still could not recover. It is so common in the ancient’s world. Without the technology, people died easily when there were high infectious diseases, such as the Bubonic plague. Without the technologies in the 1800s, the control of the plague was done inadequately. It claimed millions of people life in the Europe and Asia.

This is the topic of today, the medical technology.

In deed, medical technology is a board and controversial term on any practical application of the medication field knowledge.

In aspect, we can identify the base of the growth of medical technology, the hardware (equipment and facilities) also the software (knowledge and skill)

They both related to each other, such as the improve of equipment such as the invention of endoscopy in 1950, Helicobacter pylori was being discover in 1982 by Dr. Barry Marshall and Dr. Robin Warren of Perth, Western Australia.

It shows the relationship of how both of them improve the medical field in getting a better knowing in curling the peptic ulcer.

Medical technology can devote into 5 different divisions
prevention, diagnosis, treatment, support, and administration

I will introducing you one by one

How does hardware participate in the medical field?

There are tons of examples; therefore I do have an idea on concentrating the attention on the participation in the alimentary, respiratory and circulatory disorder securing process.

Other than the ancients type of Chinese Pulse diagnosis which is rather depends on the doctor’s experience, there are the stethoscopes invented in the 1800s which the doctors are able to hear the condition of the patients. On January 18, 1896 an X-ray machine was formally displayed by H.L. Smith. The invention of the X-ray machine did helps a lot in the process of diagnosis. It’s then commonly used, with the improvement of the photographic technology; the gastroscope with camera was developed in 1950 by a Japanese team of a doctor and optical engineers.

They are all great invention helping us in diagnosing the disorder inside our systems.

After the diagnosis, there shall be the treatment.

Talking about treatment, there are 2 method, medicine and injection as the protein form hormone or the surgery.

The development on the part of treatment is a great leap. Nowadays, there are several big pharmacy companies synthesizing new medicine, so do the hormones.( such as insulin which stimulate body organs to function the glycogenesis as to lower the Blood Glucose level)

I shall have another blog page talking about how the development of medicine later onwards. Now I am giving a gross view of the growth of technology in medical field.

However on the surgery perspective, non-invasive procedure was a gorgeous success.

Given an simple example on how the non-invasive procedure helps.

Nasopharyngeal carcinoma

a cancer originating in the nasopharynx

to undergo an open operation( the traditional one) it took at least half a day to complete. the operation procedure was first havinga cut in the neck of the patient, as to expose the infected area, thus, there will need a long time to recover from the trauma wonded from the surgery ( document from Prince of Wales Hospital in Hong Kong) Yet, with the new non-invasive procedure, the aids of the endoscope, only a small hole was opened during the operation and have the tumor removed and so as the non- invasive operation will have a less recoverable time also less pain. However a higher operation cost and takes longer time.

or there's another example from internet

Man’s Appendix Removed through Mouth

Talking about the support
