The Debate On The Health Hazards of 5G Electromagnetic Radiation

0

I have been inundated with complaints from various people on the health hazards of electromagnetic (EM) radiation from 5G networks. Several videos are circulating on social media platforms about the potential health hazards of electromagnetic radiation from 5G networks. I have written about this topic in the past but feel obliged to write about it again, in simpler terms.

In communication networks, there are two modes, the uplink and the downlink. The uplink, as the name implies, describes the communication path that allows your mobile phone’s antenna to communicate with a base station antenna, as depicted in figure 1 below, whereas the downlink represents the communication path through which the base station antenna communicates with your mobile phone.

 Fig1. Uplink (the featured image above)

Fig2: Schematic showing uplink and downlink modes

As depicted in figure 2, during the uplink, your mobile phone acts as the transmitter whereas the base station antenna serves as the transmitter, for the downlink.

The videos being circulated online expressed concerns about the EM radiation from 5G networks. This represents the downlink part of the communication system. Base stations are antennas that radiate energy in specific (or certain) directions. There are low levels of radiation exposure that are considered less harmful/safe for humans. Now, there will always be radiation exposure from antennas, what matters is if the radiation exposure is less harmful for humans? The World Health Organization (WHO) and International Telecommunication Union (ITU) have endorsed the International Commission on Non-Ionizing Radiation Protection (ICNIRP) to develop the international electromagnetic radiation exposure guidelines. These guidelines define the maximum exposure for people exposed to electromagnetic radiation up to 300 GHz; these guidelines are strictly adhered to by member countries, when deploying base station antennas. Please check the ICNIRP website for those interested in the details of the guidelines.

The uplink part (see Figure 1) is usually often neglected by mobile phone users’ but it is actually the most dangerous part of the communication modes because the phone is very close to the body (as shown in figure 1). As I mentioned previously, all antennas radiate energy; including your mobile phone’s antenna. Your mobile phone’s antenna serves as the transmitter during the uplink and radiates energy which is easily absorbed by your body (or head) because of the close proximity between your mobile device and the head (as shown in Figure 1). This is one of the reasons why researchers recommend the use of earphones during mobile phone conversation to reduce exposure.

Now, the videos being circulated online should be scientifically investigated by the relevant authorities. If the radiation exposure from any base station antenna is above the ICNIRP guidelines, such base station antenna ought to be removed. But it is important that these issues are reported to the relevant authorities and communication engineers are allowed to investigate these claims, by carrying out radiation tests rather than accepting the claims made within these videos without determining the authenticity of such claims. GSMA, in this link, had also addressed this issue.

Note: there are various ways of reducing EM radiation e.g. reducing power of the antenna, adaptive beam-forming etc.

Testing Covid-19 Vaccines in Africa – A French Researcher Goes Racist

8

Africa has contributed extensively to France in many ways. From Ivory Coast to Cameroon, Africans have supported this European country. Yet, the legendary racism in France continues to scale exponentially. As I was returning with family after Christmas, we had a lay-over in Paris. We went to the lounge and my wife presented our Nigerian passports; quickly, the lady started struggling, bringing all kinds of new rules, etc. But knowing that we were in France, and to save my time and deal with the usual demons, I took the Nigerian passports and dropped the U.S. passports before her, and magically, she started smiling. You know what? She wished she did not have Nigerians right there for no apparent reason!

But this new one has taken the “trade” to a new level – a French researcher thinks that Africans should be the labs upon which vaccines for Covid-19 (i.e. coronavirus) should be tested on. When you hear such nonsensical statements from experts, you begin to doubt what drives this world. That statement has the potency to push many Africans to AVOID any Covid-19 vaccine if the world finally comes out with one.

Dr. Jean Paul Mira and Dr Camille Locht made provocative racist comments in the wake of Covid- 19.

On live television, Jean Paul Mira suggested Africa should be the testing ground for Covid-19 vaccines due to their vulnerabilities.

Jean Paul Mira stated, “If I could be provocative, should we not do this study in Africa where there are no masks, treatment or intensive care, a little bit like it’s done, by the way, for certain AIDS studies or with prostitutes?”

“We try things because we know that they are highly exposed and they don’t protect themselves,” he said.

Camille Locht, the research director from France’s Inserm, responded: “You are right. And by the way, we are in the process of thinking in parallel about a study in Africa ….”

Shame to Dr. Jean Paul Mira. 

Sure – the current leader of France is a good friend to Africa and there are of course great people there. Yet, France and Europe seem exceedingly  lost when you see how the demons of racism are still growing from stadiums to college classrooms.

Andela’s Seni Sulyman Steps Down As Gokada Unveils Yacht

1

Seni Sulyman, Andela’s Vice President of Global Operations, has announced that he will be stepping down effective May 15, after four years with the company. He made the announcement on Thursday to the surprise of many who have expected him to carry on after helping to pull Andela through its many challenges last year.

Sulyman has overtime, acquired enormous wealth of experience working in different areas in the tech industry, but he always knows when it’s time to say goodbye.

“There is never a right time to say goodbye to a community I love from the bottom of my heart, and people I’ve built lifelong relationships with.

“After four tremendous years at Andela, I am transitioning out of my role as vice president of Global Operations and into the Alumni Network on May 15.

“I am immeasurably grateful for the privilege to have spent the last few years doing the hardest yet most fulfilling work of my career, with some of the most passionate and driven people I’ve met. My experience at Andela have permanently reinforced my sense of purpose and enhanced my belief in what’s possible when incredibly talented people from diverse cultures and contexts come together to pursue a bold mission” said Sulyman on Medium.

Andela was barely two years old when Sulyman joined them in 2016 as director of operations, and in less than a year, he became the country director of Nigeria. Andela witnessed tremendous growth under his leadership, growing by over 400%, and unveiling its ultramodern tech office in Lagos.

In just two years after he joined Andela, the company emerged number 1 Jobberman’s Best 100 places to work in Nigeria (2018), and was awarded by the US Secretary of States for Corporate Excellence.

Sulyman bagged a Bachelor of Engineering in Northwestern University and had worked with other reputable companies prior to his involvement with Andela. Konga, HP, CardinalStone, Bristow and Bain & company were among the companies he worked for before now. He is also the founder of AYPAfrica, a youth organization that focuses on nurturing talents.

In 2019, Sulyman was appointed Interim Country Director for Andela Kenya. But the most challenging change he effected in Andela was the notorious layoff of about 400 workers in 2019; it was a monumental decision that was needed to keep the company in business.

Sulyman said the decision to leave Andela was a difficult one, but there is never a better time to make it.

“This is a bitter-Sweet moment for me. It is difficult to leave when we’re still in the early days of a wicked global challenge with COVID-19 pandemic. I am also disappointed that I won’t be able to visit our various offices one more time in person due to travel restrictions imposed by various countries (which I agree with).

“I’ve second-guessed my decision to leave a few times, but there just isn’t ever a perfect time. I take comfort in the leaders and subject matter experts we have across the organization,” he said.

Sulyman plans on going sabbatical to put some of his personal ideas into practice including Real Talk Show with Seni, building a platform where entrepreneurs can share their experiences and learn from each other.

In February, Sulyman had shared his first step in making that dream come through, using his Twitter handle. It appears more time on his side will mean more of the shows after May 15. He said his most gratifying achievements is building the remarkable team leading Andela’s Africa delivery centers, and would want to continue in that vein after his sabbatical.

“After some time off, I’ll plan my next great adventure in line with my life’s purpose of building an ecosystem of exemplary African businesses and leaders, and creating commercial bridges between Africa and the world,” he said.

Meanwhile, Gokada is planning to expand its water services soon, as it appears to have introduced bigger boats to Lagos waters. The company shared a picture of its branded yacht on twitter with the caption: “We told you guys.”

Since the Lagos State Government banned the activities of commercial motorcyclists including app-based motor companies, Gokada and other ride-hailing companies have been looking for alternative fields to stay in business.

In June last year, the company introduced the waterway transport system (Gboats) that focused on the island due to limited ferries and inadequate infrastructure. The operation was limited to few Terminals at Laswa yard Falomo, Ikoyi; the Kingfisher Waterfront Jetty at Wole Olateju, Lekki; and the Paradise Jetty at Walter Carrington Victoria Island.

Much was heard of the initiative as Lagos State owned jetties were taking its campaign to many parts of the state.

Gokada said more speed boats and yachts have been added to its fleet and appears set to expand its water operations to other parts of Lagos. The introduction of yatch means the company has a plan to offer luxury and VIP services to riders.

BREAKING – Germany’s Rocket Internet Completely Exits Jumia [Updated with Video]

Use this for the the link of Tekedia mini-MBA faculty list.

This is hard news: Germany’s Rocket Internet has exited Jumia. Within  the window it sold, from Nov 8 2019 to say early February 2020, Jumia’s highest stock value was about $8.50. That is still a huge drop when you consider that the stock rose to $49.77 shortly after IPO before it lost steam. Jumia closed at $2.58 today after losing more than 8% of its value. This sector remains a challenge in Africa, and not an electronic business, as the marginal cost is all physical. The sector challenges are well documented in this seminal Harvard Business Review piece I wrote a few years ago.

German tech investor Rocket Internet RKET.DE said on Thursday it had sold its stake in African ecommerce company Jumia JMIA.N, which has seen its shares steadily fall since they listed last April on Wall Street.

Rocket Internet, which had held an 11% stake in Jumia as of Nov. 8, sold its holding between then and the onset of the coronavirus crisis, Bettina Curtze, the firm’s head of finance and investments, told journalists, declining to be more precise.

Curtze declined to reveal what proceeds Rocket Internet made from the sale, but said they were included in the 2.1 billion euros ($2.30 billion) of net cash the company had as of March 31.

Jumia shares soared when the company became the first African tech stock to list on Wall Street on April 12 but tumbled a month later after Citron Research, run by short-seller Andrew Left, questioned some of its sales figures.

In the last 48 hours, the price of Brent has gained over 20% and Nigeria’s Bonny light by over 10% on confirmation that major oil producers would meet via video conference on Monday, April 6 to discuss the falling demand for crude oil.

The meeting will include the OPEC+ group of producers including Russia. Azerbaijan also confirmed it received an invitation for the meeting.

In Nigeria, we can only look forward to the outcome of the meeting with optimism as the 10 million barrels proposed cut is just half of the current loss of demand which is about 20 million barrels per day. The cut may just be enough to stabilise prices rather than set prices northbound strong enough to build our foreign reserves.

Unlike oil prices, Investors in the stock market were not so lucky as most global market indices closed down to end another turbulent week dominated by COVID-19 headlines. FTSE 100, DAX, CAC 40 all lost points.

In Nigeria, financial sector stocks dominated the gainers’ chart but could not rescue the All Share-Index (ASI) from the Bears. The ASI lost 0.13% to increase the year-to-date loss of the market to
 21.41%. See the image below for a complete snapshot of market performance.
