ABSTRACT

Mexico is a country which more than 80% of Mexicans have a SmartPhone device and four out of ten in a smartphone, so that mobile marketing is a sector that is clearly expanding. 

Several epidemiological studies regarding the use of mobile phones and brain cancer. Male infertility occurs when a man has difficulty in getting a woman to become pregnant after having tried it for at least a year, which can be caused by problems Physical, hormonal, lifestyle or environmental factors.

The most common cause of male infertility is a varicocele (enlarged scrotum) on one or both sides. The relationship between constant use between mobile phones and male infertility is one: radiation affects the morphological characteristics of the affected spermatozoa characteristics for fertilization of the ovule. The most radio-sensitive part of the male reproductive system is the testicle and, within it, the Spermatogonia, since they fulfill the requirements expressed in the Basic Law of cellular radiosensitivity. The effects of radiation on the organism can be classified into genetic and somatic effects. The genetic effects are those that affect the germinal cells and, given the function of these, can be transmitted to the offspring. However, the somatic effects are those that only affect the cells of the irradiated individual. Deterministic effects are characterized because their severity depends on the dose of absorbed radiation.

CONCLUSIONS   

                                               

The most radiosensitive part of the male reproductive system is the testicle and, within it, the spermatogonies, since they fulfill the requirements expressed in the Basic Law of cellular radiosensitivity. The primary effect of radiation on the testis is the decrease in the number of spermatogonia, which causes a subsequent decrease in the number of spermatozoa. There is a certain period of temporary fertility, followed by a phase of sterility, more or less durable depending on the dose received. When studying the sixth semester of CECyT # 15 from 17 to 20 years of age exposed to the ionizing and non-ionizing radiation of cell phones, the results showed that the patients are within normal morphology and mobility values , However they are elevated in a certain way, if patients are constantly using the cell phone in the pocket or other place near the reproductive system, they are much more likely to infer infertility than those who do not carry it in the pocket, this is Can associate that they were exposed to this radiation for a mean lapse, so it is important not to keep the cell in the pocket of the pants in a usual way due to the constant radiation emitted by these devices.

With this, it is concluded that the men who keep their telephone sets in the bags of their pants or the belt have a low amount of sperm but nevertheless are within the established reference values. It is possible to mention that the hypothesis was not verified because it was not possible to control the time that they took using the cell phone, much less the place where they carry his cell phone.

Mark Zuckerberg

Mark Zuckerberg, the American computer programmer, who was born in New York in 1984, was one of the founders of Facebook.

In his teens, he began to write software programs as a hobby. After school, he went to Harvard where he studied computer science and sociology. While he was there he created a website called Facemash which allowed students to share photos. It was shut down by the university, but it inspired him to create Facebook which he launched from his room in 2004.

He left Harvard and moved to California with Dustin Moskovitz who had been his roommate and together they made Facebook and international success.

In 2012 Zuckerberg married Priscilla Chan who he had dated for nine years.

Dear Mr. Perez,

I am writing to complain because well instead of 2 x 3 cm components; you sent me 3 x 2 cm components and the D70 motor you sent doesn´t work! I talked to someone from the company and he said he would send it back to me. Your website says that items in stock are delivered in 48 hours.

Two weeks passed, and nothing arrived. However, I notice thay payment had been taken from my credit card. I phoned your custumer service line, and the person that spoke to, receptionist Lara, was very rude and  unhelpful. She said that the packaging was not in stock, and that she didn't know when they would arrive. She could not explain why the money had been taken from my card.

I have bought many things from you over the years in Twiney's, and I have always had good service.  I can only imagine that this is a departure from your usual high standars, and I am sure you will be able to resolve the situation in a satisfactory way.

I look forward to your reply and a resolution to my problem.

Yours faihfully.

Hank Weston.
