@moscow406.
I think you're not alone in the same case...link up or do a low key survey of what other medics do outside studies... just keep networking among your colleagues or other institutions if possible...

It seems everyone knows what medics go through...so don't over do it so that you don't also lose track on the major stuff.

Someone once shared this..

Yea, too bad a lot of people aren't giving opinions. Seems like it's been wired for medical students to think about studies only.
Not really.... what works for medic A might not work for B. I will suggest you study yourself and check what you really like, the off class stuff you spend quality time with, like your passion and then start investing on it.... turn it business.

Good morning nairalanders. Lemme just get straight to the point.

So I'm in preclinicals and I must say it's really a big deal, trying to assimilate a lot of information in a somewhat short time. Due to this Corona break which has extended past what I imagined, I realised that 4 months has gone (whew! just like that), no job, no trade; because I was mainly focused on my studies in school.

REASONS FOR THIS POST

A front page post mentioned a person who knew a medical doctor but also versatile in computer programming (Nigeria's educational system isn't flexible enough for this except the person learnt prior to entering school).
A friend of mine (same course) is trying to learn html/CSS, and I knew it'd take time because I tried it before gaining admission and it took time to get accustomed to it.(I stopped a few years back though).
Studying Medicine and surgery requires utmost dedication and hard work, the little I've seen reminds me of this fact everyday.
Nigeria as a country is failing with each passing second, I don't see this country improving by the time I graduate.
I don't want to put all my eggs in a basket.

My questions are:
As a medical student, is there any career that can go along side studying medicine?
Hopefully schools resume this year, what kinda side business can go along the course? Or any areas of development that'll go a long way.
Good question..

How to calculate ratings of solar materials needed to power your house ( Solar panels, batteries, inverters etc).
Assuming, you make a scale of preference of Electrical appliance you need at home , and among those you can't do without include
1) television
2)lights (4 bulbs)
3) personal computer/ laptop
4) fan (2 of them)
5) decoder
6) home theatre

Again, assuming you need the above listed Electrical appliances to be powered for at least 12 hours daily, using Solar power generation method; Then you can actually calculate the ratings of materials ( Battery, Solar panels, inverter and charge controller) needed to make it possible, without involving the services of a solar Engineer, who will be demanding certain amount of money for "Load survey" and consultancy

THE CALCULATIONS.
If your load have the following Electrical load details on the name plate.
Television 120wts,220v,0.8p.f
Fan (2) 120wts (i.e 60wts each), 220v,0.8p.f
P.c. 150wts,220v, 0.8p.f
Light(4) 200wts (50watts each),220v,0.8p.f
Home theater 100wts,220v,0.8p.f


INVERTER CALCULATION
Inverters are rated in either Apparent power (VA) or Real power (watts).The rating will be clearly written on the inverters nameplate.
Note:
Apparent power(Va) = real power(wts)÷ power factor (p.f).

Since apparent power gives a better and more correct value of the load; we will use apparent power for this calculation.

Television = 120wts/0.8 = 150va
Light = 200wts/0.8= 250VA
P.c = 150wts/0.8=187.5Va
Fan= 120wts/0.8= 150VA
Home theater = 100wts/0.8=125VA

TOTAL LOADS of appliance (TL)
Real power= 120+200+150+120+100 =690wts

Apparent power
150+250+187.5+150+125= 862.5VA


SIZE OF INVERTER'S
If 20% additional load is taken into consideration for future expansion.

Then
Additional further load expansion (AL) = 20%
Efficiency of the inverter (Ei) = 90%


Size of inverter (S of I) = TL × [ (100+AL) ÷Ei]


S of I = 862.5 × [( 100+20) + 90]
S of I = 862.5 × 1.3333
S of I = 1150VA
= 1.15KVA
The size of inverter needed should be equal or greater than 1.15KVA.


TO DETERMINE THE SIZE OF THE BATTERY
If
Total load (TL) = 862.5VA
Battery Bank voltage (Bv) =24v
Required battery backup time (Rbb) = 12hours
Battery efficiency (Eb) = 90%

In Ideal scenario
Battery rating (AH)= (TL × Rbb) ÷ Bv

= (862.5×12)÷24
=431.25Ah

Considering losses and other factors like battery temperature

Assuming the operation temperature of battery (O.T) is 46°c.
Then the operation temperature correction of battery at 46°c at 90% battery efficiency is = 0.87
"You can Google this"

Battery rating formula becomes.
= (TL × Rbb) ÷(Eb ×Bv×O.T× Ei)
= (862.5 ×12) ÷ (0.9×24×0.87×0.cool
=688.4Ah
Hence the battery needed should be rated at about
688.4Ah,24v.

Note: getting one battery if that rating will be a Herculean task. But we achieve it by connecting two or more batteries in a particular pattern.


HOW TO DETERMINE THE RATING OF SOLAR PANEL.
First, we need to find the changing current which is always taken to be "one tenth" (1/10) of the battery AH.

688 × (1/10) = 68.8 A.

Power rating of panel = battery bank voltage × charging current.
= 24 × 68.8
= 1651.2watts solar panel.
The number of solar panel is determined by the rating of solar panels.
We have panels ranges for 50watts solar panels
100wts
And even up to 450watts.

To DETERMINE THE SIZE OF CHARGE CONTROLLER.
The charge controllers should be bigger than the charging current.

Since the charging current is 68.8A
Then a solar controller of 70Amps upwards is needed


To determine the time needed to fully charge a battery (T)

T = Ah/A
= 688/68.8 = 10hours.


Note that because of losses between the panel and charge controllers, it might take much time to charge.

EducationRe: Is An F Grade Much Better Than a D And An E ? by Hahjascho(m): 1:06am On Jul 14, 2020
It's not better pls. Let's say someone had F in a 3unit course. Then, it will be 0points (out of 15)/3.

If he now rewrites it, say he got A, then the calculation will go thus...(0) + (15)/3=. What this means is that, 15 point is lost from the previous Cgpa calculation...i.e 0/3 in that course unit which will drastically suck your Cgpa for that semester... due to the increased number of load unit with nill points added. It's like adding 0 to the previous 4.5cgpa (e.g 135 + 0/ 30 +3) and dividing after 3load unit is added..(135/33)= 4.09. grin

Rewriting it simply means you're registering for another course unit.

If it was D or E, it means you either scored 6 or 3 out of the possible 15 (instead of 0 for F)... for that same semester.

Getting F will have done the harm already just before rewriting it....if you like gets 5As, the first would still have affected the current Cgpa just before rewriting it. I hope you understand. The higher the credit load units, the more risky your Cgpa becomes.


What the Op is insinuating is only feasible if the failed course can actually be removed... which is however not possible or when you get As in more of other courses you will be offering.
Those who understand what it means to go around campuses with calculator just for the sake of CGPA can well, relate with my points.

Please I want to know if it is still possible to graduate with a first class after been in second class upper in 100 level.

Is it still possible to graduate with a first class from 200level to final year, 400level.
This has been bothering me because I really need a first class to source for full scholarship to further my studies abroad.

Please I need your inputs on this. First Class graduates, did you start getting first class from 100level till final year?
