Beirut Explosion : All you need to know

Published

on

Jaw dropping moment for world. An explosion in Beirut, the capital of Lebanon, a country in western Asia, was Tuesday caught on camera and widely circulated on social media. The footage showed smoke billowing near the port area of the city, shortly before a powerful blast sent up a bigger cloud of smoke and a shockwave across the city, throwing the videographer off his feet.

The vibrations of the blast, which was initially misconstrued by some as detonation of some nuclear device, were even felt around 240 km away in Cyprus.At least 100 people were killed and nearly 4,000 injured in a massive explosion at Lebanon’s capital Beirut. The explosion, according to the Lebanon government, was of over 2700 tonnes of ammonium nitrate stored for six years in a warehouse in the port. Multiple reports suggest that a huge tremor-causing explosion was preceded by a fire, possibly of firecrackers.

Where did the ammonium nitrate come from?

In 2013 a Moldovan-flagged ship, the Rhosus, entered Beirut port after suffering technical problems during its journey from Georgia to Mozambique, according to Shiparrested.com, which deals with shipping-related legal cases.The Rhosus was inspected, banned from sailing onward and was shortly afterwards abandoned by its owners, sparking several legal claims.

Its cargo included the ammonium nitrate, which is used as a fertiliser and as an explosive.It was stored in a port warehouse for safety reasons, the report said, and it remained there for the next six years.

There are a lot of rules around storing ammonium nitrate, particularly around fire-proofing, because it is so highly explosive if it comes into contact with flames.

What is Ammonium Nitrate?

Ammonium nitrate is a chemical compound .It is a white crystalline solid consisting of ions of ammonium and nitrate. It is highly soluble in water and hygroscopic as a solid, although it does not form hydrates. It is predominantly used in agriculture as a high-nitrogen fertilizer. Global production was estimated at 21.6 million tonnes in 2017.

Pure ammonium nitrate is not an explosive on its own. It is classified as an oxidiser (Grade 5.1) under the United Nations classification of dangerous goods. If mixed with ingredients like fuel or some other contaminants, or because of some other external factors, it can be very explosive.

However, for combinations to explode, triggers like detonators are required. Many Improvised Explosive Devices (IEDs) used by terrorists around the world have ANFO as the main explosive, triggered by primary explosives like RDX or TNT. In the majority of terror attacks in India, including those in Pulwama, Varanasi, Malegaon, Pune, Delhi, Hyderabad, and Mumbai, ammonium nitrate has been used along with initiator explosives like RDX.

Impact of explosion :

In Beirut, the blast affected residents living as far as 10 kilometres away from the site. It even damaged the Baabda Palace, the residence of the Lebanese President. “Doors and windows in several of the palace’ wings were dislocated,” NNA reported. However, no one was injured.

Meanwhile, the explosion was felt nearly 250 kilometres away, in the neighbouring island of Cyprus, according to the European-Mediterranean Seismological Centre (EMSC). CNN reported that the blast created seismic waves equivalent of a magnitude 3.3 earthquake.

Other countries reactions towards blast:

Indian Prime Minister Narendra Modi on Wednesday expressed shock at the loss of lives in a massive explosion that rocked Beirut and said India’s thoughts and prayers are with the bereaved families and the injured.

US President Donald Trump in his briefings to the press on Tuesday called the incident to be an ‘attack’, something which has since been denied by US officials, as reported by the US media. The blast casualties have overwhelmed the health system of the country which has been in a serious financial crisis and because medical facilities have themselves been hit by the explosion.

UK’s Foreign Secretary Dominic Raab put out a tweet expressing solidarity with Lebanon. “My thoughts and prayers are with those affected by the devastating explosion in Beirut today. The UK stands in solidarity with the people of Lebanon and is ready to offer help and support including to those British nationals impacted,” he said.

French President Emmanuel Macron said he would send “rescue and aid” to Beruit, while Angela Merkel said Germany would offer Lebanon its help.

Why blast complicated condition in Beirut

Already, the country was suffering through Covid 19 pandamic. Economic condition of country was not stable, the blast created worst situation. There was huge loss of properties and many of people became homeless.

Lebanon’s economy minister said Wednesday that the nation has less than a month’s reserves of the grain but enough flour to avoid a crisis, the economy minister said on Wednesday. Raoul Nehme told Reuters that the country’s needed reserves for at least three months to ensure food security and was looking at other storage areas.

Latest information related to Beirut Lebanon:

1.There are numerous reports of children who have been separated from family members, some of whom are still missing;

2.At least 12 primary healthcare facilities, maternal, immunization and newborn centres in Beirut have been damaged, impacting services for nearly 120,000 people;

What is Oncor and its outage.

Published

on

what is Oncor ?
More than 10 million Texas residents receive energy from Oncor through their
chosen retail electric provider. But we don’t just serve Texas; we live here too. Your
neighborhoods are our neighborhoods. That’s why we’re honored to deliver safe,
reliable, clean energy using innovative technologies and programs while also
providing exceptional customer service. Use this site to look out energy-saving tips
to manage your invoice, get help together with your energy service, and access
information about our education and safety programs.

History of oncor
With roots in Dallas Power & Light (DP&L), Texas Electric Service Company
(TESCO), and Texas Power & Light (TP&L), Oncor was created in 2007 when
Energy Future Holdings (EFH) purchased a majority stake in TXU and separated
Oncor from its other holdings by a ‘Ring-Fence’. This structure was meant to
protect Oncor customers from bankruptcy in other EFH holdings. They were privately
held by EFH, which declared bankruptcy in April 2014. last, Sempra Energy
completed its acquisition of EFH in March 2018. This transaction included EFH’s
approximate 80-percent indirect ownership interest in Oncor. The close of the
transaction creates a utility company with the foremost important U.S. customer
base.
On November 9, 2017, Oncor and Sharyland closed a giant asset swap agreement.
For details on the agreement, read The Oncor/Sharyland Deal: How Customers Will
Benefit. for purchasers, this means that each one 54,000 retail Texas Sharyland
customers are transitioning to Oncor in early 2018 and may get to need advantage of more favorable electricity delivery rates. This includes the cities of Midland, Big
Spring, Stanton, Brady, Celeste, McAllen, and Greenville. All customers should be
transitioned by January 9, 2018 and may receive their last account with Sharyland
rates soon thereafter. Going forward, customers will see Oncor delivery rates on
their bills.

why are charges so high?
As many Oncor customers know, TDU charges alone can add 1/3 or more to your
monthly bill because they depend upon what quantity electricity you utilize to power
your home. for example, the Oncor rate is 4.1867 cents per kWh. If you utilize 1000
kWh per month, you’ll be charged $41.87 to possess that 1000 kWh delivered to
your home. Add in Oncor’s customer charge of $3.42 and your total monthly delivery
charge roughly involves $45.29!
And that doesn’t even include the electricity you actually used!
While these charges aren’t welcome expenses, remember that Oncor is required by
the State of Texas to reliably operate and maintain a transmission and delivery
network that’s over 103,000 miles of power lines. This same network delivers power
to some 420 cities and towns. Keeping their an element of the ERCOT electric grid
running smoothly to supply nearly 10 million people with reliable energy altogether kinds of Texas weather is an intensive and expensive job.
Before Oncor can change its rates, it must file letter of invitation with the
final service Commision of Texas. The PUC updates rates (also called “tariffs”) twice
a year. Oncor and other TDUs can file rate change requests whenever they require
but all such changes must be first reviewed and approved by the commission
before they’re going to get in effect
how are Oncor rates set
here are multiple components included within the TDU delivery charges, with
fascinating names like
Energy Efficiency Cost Recovery Factor (EECRF)
Transmission Cost Recovery Factor (Rider TCRF)
Accumulated Deferred Federal tax (ADFIT) Credit
Transition Charges (Schedule TC2, TC3, SRC, and TC5)
Most REPs summarize these TDU delivery charges on your monthly electric bills.
you’ll not see this level of detail on your monthly residential bill.
The PUCT maintains official copies of the tariff documents on their computing
machine.

Why do the fees change so often ?
Each of the regulated utility companies is entitled to assemble 100% of their costs
from their rate payers, and receive a guaranteed rate of return. That’s because they
provide a critical public service: delivering electricity, maintaining the infrastructure,
and responding just just in case of an emergency.
The Public Utility Commission of Texas reviews and approves each utility’s rate
case.
The items in each rate case may include costs from hurricane or storm recovery,
upgraded service equipment, or bond issues and financing costs for system
upgrades.
how to read Oncor meter
The meter face on your Smart Meter shows three separate rotating displays. Each
display flashes for five seconds. The displays include:
Status of your electricity service — is that the ability on or off? What does OPN and
CLS means?
Cumulative electric usage — utilized by your Retail Electric Provider in bill
calculation
Electric demand reading — a view for AEP Texas operational use only
New Digital Smart Meters
The Power Status Display tells you whether your electric service is on. you will see
either:

OPN — this means your power is off.
CLS — this suggests your power is on.
Power Status Display
Cumulative Electric Usage Display
The Cumulative Electric Usage Display shows your cumulative usage in kilowatt-
hour (kWh) up to your current billing period. Your Retail Electric Provider uses this number to calculate your bill. you may also wish to hunt advice from this number if you’re keeping track of your kWh usage.
A kilowatt-hour is also a unit of electrical consumption up to the number of electricity
needed to burn ten, 100-watt light bulbs for one hour.

The Reference no 1 is exclusive to the Cumulative Electric Usage Display. The
meter number could also be a singular identifier for your meter.
Cumulative Electric Usage Display
Electric Demand Reading Display (For AEP Texas operational use only)
The Electric Demand Reading Display can be a kilowatt (kW) reading utilized by
AEP Texas. (It isn’t utilized in billing calculations.)
A kilowatt might be a unit of electrical consumption adequate 1,000 watts.
The Reference Number 21 is exclusive to the electrical Demand Reading Display.
The meter number may well be a novel identifier for your meter.

Neuralink: a deeper introspection

Published

on

6th sense of Human beings the Neuralink- Neuralink is a medical device developed in order to track and enhance brain activity. Moreover, it is like a Fitbit that tracks brain activities like neuron spike. Elon Musk said that the device will also be able to help regain someone’s eyesight even if they’ve lost their optic nerve. He said that this technology will be able to fix everything that’s wrong with the brain. With complete symbiosis of the tech, humans will be able to interact with each other without the need to talk.

It will be surgically implanted into the brain and with it, one will be able to communicate with machines and control them. For now, human trials are not yet begun but would start at the end of 2020. Furthermore, it will also help study the electrical signals in the brain and help cure various medical problems. Before testing on humans, Neuralink prototypes have been tested on rodents, monkeys, pigs, etc.

Before peeping deeper into Neuralink let’s understand the human brain first.


There are 86 billion Neurons in our Brain. These neurons consist of 3 parts: a dendrite that receives the signal, a cell body that computes the received signal, and an axon that sends the signal out.


Neurons are connected through Synapses. The neurons of your brain connect each other to send and receive signals through axon-dendrite connections called synapses. Neurons communicate through Electric Signals. These signals can be recorded in the brain. Recordings from many neurons allow us to decode the information and it represents intended movements.


To understand how Neuralink works, we must understand how our brain sends information to different parts of our body using neurons. These neurons in our brain connect to form a large network and communicate using chemical signals called neurotransmitters.

This reaction generates an electric field to record the reactions. These electrodes translate electrical signals into an algorithm that a machine can read. This is how Neuralink will be able to read what one is thinking and find a way to talk to machines without uttering a single word. It’s all your thoughts and link’s action.


The neural implant will let you control a computer or mobile device anywhere you go. Micron-scale threads are inserted into areas of the brain that control movement. Each thread contains many electrodes and connects them to an implant, the Link.


The link:

It’s a sealed, implanted device that processes and stimulates, and transmits neural signals.


Neural threads:

Each small and flexible thread contains many electrodes for detecting neural signals.


Charger:

A compact inductive charger that connects to the implant wirelessly to charge the battery; same as a smart-watch or fit bit.

Precision Automated Neurosurgery.


The threads on the Link are extremely fragile and flexible that they can’t be inserted by a human hand. Hence neurosurgeons would be provided with a robotic system that can reliably and efficiently insert these threads. The robot would be able to insert the link within an hour without general anesthesia and the patient would be able to leave the hospital on the same day.

Robots will do everything from the incision, removing the skull, inserting electrodes, placing the device, and then closing it up. These robotic systems were tested on numerous pigs used to test the device. This system has no room for errors. The Head of the machine holds and guides the needle that performs the operation and contains a large number of cameras to capture the whole brain.

How Neuralink will help to overcome mental disorders?


The Neuralink aims to fight neurological disorders like Alzheimer’s disease, dementia and epilepsy, spinal cord injuries, and other medical problems. The link is expected to even fight with common anxiety and depression yet that’s not proven. By taking primitive measures of implementing the Neuralink slowly and gradually we can hope best for it. There are high abilities and possibilities that Link could help fight a large number of medical illnesses and aims to create an affordable solution for people who lack the essential needs of medical treatment. At its level best, it will help to control the number of suicides that end lives before help can be received.


For now, those goals are very much out of reach. Scientists need to learn far more about the brain and how it works for any of those ideas to become reality. The brain is still mysterious and the neurological causes of addiction and anxiety are still unclear.


Why is Elon Musk testing his implant on Pigs?


In August 2020, Elon Musk’s 3 pig trial got rearing spotlight. The Neuralink implant was tested on 3 pigs; on 1st with no implant, on 2nd with an implant for some days and later it was removed and the 3rd pig still has the implant in her brain. The experiment of 2nd pig was done to show that if someone wanted to remove the link, they should be able to live a happy and healthy life after that. 3rd pig’s implant is active to track down all neural movements and to list down moments of snout and sniffs.


Hiring engineers for neurotechnology firm Neuralink


Neuralink is almost done dealing with a neuroscience background. The chip is an electrical device that requires mechanical/software engineers to deal with. It would be easier for these engineers to sort out problems like processing, indictive charging, power mgmt, etc. Most importantly, great problem-solving skills, solving high-volume, high-reliability, low-cost production problems are especially valued.

In the end, let’s hope best for the future of brain interfaces and inventing new technologies that will expand our abilities, our community, and our world.

The Presidential elections.

Published

on

How are presidential elections held in the USA?
Unlike India where citizens directly vote for their preferred party, the USA’s election system
is more complicated and distinctive from that of India.
In the USA, the electoral college system exists which means that voters are adjudicating
upon state-level contests, rather than the national one. These are called electoral
colleges, they initialize a representative of trump or Biden, often acknowledged as
Electors
There are 538 electors present, who further vote for the resident on behalf of the voters in
their state — the winning candidate is whoever gets a majority of 270 or more.
Presidential elections: 2020
The product of the US presidential elections is not obtrusive as of now, both candidates
claim to possess a potential path to victory,
Mr. Trump has even lawsuits in the two states where Mr. Biden holds a lead, several
substantial states are contemplated to conclude the counting by the end of Friday, but the
election result may remain in the state of irresolution for days.
Mr. Biden is still holding slim leads in several key states if the trend continues, Mr. Biden
may propel to gain the Electoral college and the presidency.

Mr. Trump’s prospect of acquiring his second term is attributed to his capability of holding
on to states like Georgia and Pennsylvania.
Results so far
Let’s disintegrate the convoluted election results,
Mr. Trump has encompassed a win in Florida, Ohio, Texas, and Lowa respectively, Mr.
Biden has entrenched a win in Michigan and Wisconsin and the results remain uncertain
in Arizona, Pennsylvania, North Carolina, and Georgia.
In Arizona, Joe Biden has received 500,000 votes and still counting and it even
accounts for 60% of the population of the state.
In Nevada, reports say that Mr. Biden has achieved a very narrow lead and the
counting is going at an adequate pace.
In Georgia, Mr. Trump has a very attenuate lead over Mr. Biden, the Secretary of state
has announced that results will be announced by midday Thursday(local time).
In Pennsylvania, there are more than 580,000 ballots left to count, but so far Mr.
Trump leads Biden
