We explain what types of motors exist and what their characteristics are

At the time of Buying a car not so long ago you only had to worry about whether a gasoline or diesel engine would suit you, however, nowadays the wide range of propellers has revolutionized the market and raised many doubts in society.

Specifically, we can divide them into four main groups: gasoline, diesel, electrified engines and their variants, and those that run on LPG or CNG. From the Spanish Scrap Operations Network (RO-DES) give us a brief summary of the characteristics of each of these types of thrusters, and so you can determine which one goes with you the most.

Gasoline engines

Gasoline engines, also known as four-stroke engines, are those that work with a thermodynamic base that is responsible for converting the chemical energy of ignition, caused by the mixture of air and fuel, into mechanical energy. In this way, the vehicle obtains the energy necessary to carry out its movements. And said operation in four-stroke cycles that could be roughly classified as follows:

-Inlet phase: the intake valve opens, which allows the mixture of air and fuel to flow into the cylinders.

-Compression phase: during this phase, the valve closes and the piston rises to compress the mixture.

-Explosion phase: the spark plugs originate the spark necessary to produce the explosion and the descent of the pistons.

-Exhaust phase: the exhaust valve opens and the pistons are raised to expel the burned gases to the outside

Diesel engines

In general, diesel engines are mainly used in means of transport that require an extra dose of power and that are designed for a higher daily work load, such as industrial vehicles, cargo vehicles, machinery, aeronautical means, etc. However, since this type of engine was born from the hand of Rudolf Diesel in 1893, the technology has also spread to private means of transport, currently reaching the number of gasoline-powered vehicles in Spain.

Diesel engines operate similarly to gasoline engines and their process can be divided equally into four times, which are as follows:

-Inlet phase: air filling occurs and the intake valve remains open while the piston descends towards the bottom dead center.

-Compression phase: the intake valve closes when the piston reaches the bottom dead center and begins the journey to the top by compressing the air inside the cylinder.

-Combustion phase: the injector sprays the fuel into the chamber and it ignites immediately when it comes into contact with the hot air.

-Exhaust phase: burned gases are expelled and inertia is allowed to start the cycle again.

Electric motors

Although it may not seem like it, electric motors predate diesel or four-stroke gasoline. Between 1832 and 1832 Robert Anderson developed the first automobile with a pure electric motor, capable of transforming electrical energy into mechanical energy by means of the magnetic fields it generates, without the need for explosions or combustions typical of gasoline and diesel engines.

Nowadays when we think of pure electric vehicles, we usually refer to BEV, or battery electric vehicles. However, in the market we can find other options such as FCEV, fuel cell, which are combined with hydrogen, and HEV and PHEV, known as hybrids and plug-ins respectively, that alternate a permanent magnet electric motor with an internal combustion one (mainly gasoline).

LPG and CNG engines

Vehicles that run on alternative fuels such as LPG (liquefied petroleum gas) or CNG (compressed natural gas) are gaining ground in the automotive industry, and more and more manufacturers are betting on marketing versions of some of their models. , powered by this type of fuel.

Either option, LPG or CNG, favors increased engine life, since they do not generate as much wear on the cylinders and less waste is deposited in the system. However, it must be taken into account that sometimes it hinders lubrication and can deteriorate the valves at a higher speed, something that we can solve thanks to preventive mechanics and good maintenance.


The first blood test that accurately detects more than 50 types of cancer




A study published today in the journal Annals of Oncology presents the first blood test that can accurately detect more than 50 types of cancer and identify which tissue the tumor originated from, many times before there are clinical signs or symptoms of the disease.

In the article, which is part of the Circulating Cell Free Genome Atlas (CCGA), the researchers show that the test, which could be used in national cancer screening programs, has a rate of 0.7% false positives, that is, less than 1% of people would be mistakenly identified as cancer carriers.

For comparison, approximately 10% of women are misidentified as cancer carriers in national breast cancer screening programs, although this rate may be higher or lower depending on the number and frequency of exams and the type mammography performed.

Furthermore, the new test was able to predict the tissue in which Cancer originated in 96% of the samples, and was accurate in 93%.

All tumors release DNA fragments into the blood and this contributes to what is known as cell-free DNA (cfDNA).

All tumors shed fragments of DNA to blood and this contributes to what is known as Cell Free DNA (cfDNA). However, since cfDNA can also come from other cell types, it is sometimes difficult to determine whether the cfDNA comes from tumors.

Now, it is possible to solve this problem thanks to this new blood type, which analyzes chemical changes in DNA called “Methylation” that generally control gene expression. Abnormal methylation patterns, and the resulting changes in gene expression, may contribute to tumor growth, so these signs in the CDNAs have the potential to detect Y locate cancer.

The blood test is directed at approximately one million of the 30 million of “zones” of methylation in the human genome. The researchers have used a machine learning algorithm to predict the presence of cancer and tumor type based on methylation patterns in the cDNA released by the tumors.

The algorithm had been designed using a database of cancer and non-cancer signal methylation in cfDNA. The database is believed to be the largest in the world and owned by the company involved in this investigation, GRAIL Inc.

“Our previous research showed that the methylation approach outperformed both the entire genome and targeted sequencing in detecting different types of fatal cancer at all clinical stages and also in identifying tissue of origin. It also allowed us to identify the regions of the genome that provide the most information, which have now been used for the refined methylation test of this report, “states the main author of the article, Michael Seiden, President of US Oncology (USA).

It allowed us to identify the regions of the genome that provide the most information, which have now been used for the refined methylation test of this report.

The researchers analyzed blood samples from 6,689 participants with previously untreated cancer (2,482 patients) and cancer-free (4,207 patients) from North America, which were divided into two groups: preparation and validation. Of these, the results of 4,316 participants were available for analysis: 3,052 in the preparation group (1,531 with cancer and 1,521 without cancer) and 1,264 in the validation group (654 with cancer and 610 without cancer). In total, more than 50 types of cancer.

The machine learning algorithm analyzed participants’ blood samples to identify methylation changes and classify the samples as cancerous or non-cancerous, and locate the tissue of origin.

The system proved to be valid in both the preparation and validation groups, with a false positive rate of 0.7% in the validation set.

Furthermore, their ability to correctly identify when cancer was present (the positive rate) was also demonstrated in both groups. Thus, in 12 types of cancer that are often the most deadly (anal, gallbladder, intestinal, esophageal, stomach, head and neck, liver and bile ducts, lung, ovarian and pancreatic cancer, lymphoma and white blood cell cancer, such as multiple myeloma ), the positive rate was 67.3% in clinical stages I, II and III. These 12 tumors represent approximately 63% of cancer deaths each year in the US. USA And, currently, there is no way to detect them before symptoms appear. The positive rate was 43.9% for all types of cancer in the study at the three clinical stages.

The researchers also explain that detection improved with each stage of cancer. That is, in the 12 cancers previously specified, the true positive rate was 39% in stage I, 69% in stage II, 83% in stage III, and 92% in stage IV. For the more than 50 types of cancer, the corresponding rates were 18%, 43%, 81%, and 93%, respectively.

Regarding the origin of the tumor, the analysis showed a precision of 93% in the validation set.

Early detection of more than 50% of cancers could save millions of lives each year worldwide

The researchers continue to validate the test in three large prospective studies in the US. USA (STRIVE and PATHFINDER studies) and the United Kingdom (SUMMIT study), and to examine their feasibility for population screening.

The editor in chief of «Annals of Oncology », Fabrice André, research director of the Gustave Roussy Institute, Villejuif (France,), comments:« This is a study historical and a first step towards the development of easy to perform detection. Early detection of more than 50% of cancers, he stresses, could save millions of lives every year worldwide and drastically reduce morbidity induced by aggressive treatments ».

And he concludes that, although the numbers are small, «the performance of this new technology is particularly attractive in cancer of pancreas, for which mortality rates are very high because it is usually diagnosed when it is in an advanced stage».


What types of tests to identify patients with coronavirus exist and what is their reliability?



The so-called «quick tests»To detect patients with coronavirus They have just arrived not without some controversy to the Spanish health system. But what diagnostic tests exist and are currently being used? How reliable are they? How long does it take to reveal the results? Can we expect new better tests than the ones we have now? Here are some answers.


** Functioning: It is based on the polymerase chain reaction, a reaction created in the laboratory to amplify DNA chains. However, the viruses have RNA, so a sample is first extracted from it, purified and mixed with an enzyme called reverse transcriptase (hence the acronym RT), which converts single-stranded RNA into double-stranded DNA. It is then added to a test tube along with primers — short sections of DNA designed to bind to the virus — nucleotides — the building blocks that make up DNA — and a DNA-building enzyme. In this way it is amplified. The next part is to detect the presence or not of the virus SARS-CoV-2, causing the disease COVID-19: Fluorescent dyes are added, which will illuminate the sample as more copies are produced. However, not every time the test tube is illuminated it will be an unequivocal sign of infection: only if it crosses a certain fluorescence threshold, the test is positive. If the virus was not present in the sample, the PCR test will not have made copies, so the threshold will not be reached and, in that case, the test will be negative. “It’s about a genetic test that tells you how much infectious virus the patient has, looking directly at the genome », he explains José Antonio López, full professor of Microbiology and director of the NeuroVirology group at the Department of Molecular Biology of the Autonomous University of Madrid.

** Methodology: Personnel trained to do this test introduce a stick normally in the nose (although sometimes it is in the throat). From there, the sample goes to a specialized laboratory.

** Weather: In addition to the time in which the test is performed (10 minutes), the sample goes to the laboratory, where the virus is inactivated (10 or 15 minutes), the genetic material is extracted (20 to 30 minutes) and is processed in the equipment corresponding (2 hours). With all these processes, the PCR test is taking as long as minimum 4 hoursAlthough techniques are being developed to cut times in half or even less.

** Reliability: is the most reliable available to date. It can detect amounts of 20 copies / ml -or even less- of viral genetic material and can also detect the disease in the early respiratory stages. “The positive predictive value is very high, higher than 90%”, explains López, who nevertheless explains that, as has happened in China, there may be cases in which “the viral load is already low and is not detected in the mouth , but that is present in the intestines and, therefore, continues to be excreted, and can lead to new infections ».

** Professionals: Only trained personnel to perform this specific test. “It is not only the collection of samples, but they are needed people who interpret laboratory data», Affirms the expert.

** Availability: They are being carried out from the beginning of the pandemic, although new more effective updates are almost ready. “In a few days, rapid PCR systems will be commercialized (less than an hour) that will allow rapid and correct diagnosis of patients. Laboratories must have access to said tests and have the necessary consumables and devices to start them up immediately, ”they claim from the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC).


** Functioning: “They are based on a paper immunochromatography, that is, a platform that has some” stuck ” viral antigens that detect certain virus proteins “, they explain from the National Center for Microbiology (ISCIII). That is to say, the antibodies (viral antigens) recognize the proteins of the coronavirus, ”says López.

** Methodology: Its operation is similar to a pregnancy test, except that the samples are collected from the nose or throat. Once taken, the strip of paper is expected to reflect colored bands determining if the test is positive, negative or inconclusive.

** Weather: 10 to 15 minutes.

** Reliability: The probability of correctly diagnosing a person with coronavirus (which in this case is understood by the sensitivity of the test), depends on the phase in which the patient is: the more symptoms, the more viral load and vice versa. The problem with these tests is that according to SEIMC itself, the sensitivity of these tests is 30% when it should be, at least 80%. Also, in doubtful cases, confirmation with another PCR test is needed.

** Professionals: “They can be done at the home of a suspicious case, always supervised by a health professional,” they say from the ISCIII.

** Availability: The Ministry of Health is generalizing this test throughout Spain.


** Functioning: It works under the same principles as the antigen test, but instead of looking for the virus protein, it reacts to the antibodies generated by the patient himself when contracting the coronavirus. Thus, it can detect immunoglobulins M (IgM), which arise from 6 or 8 days after infection; or immunoglobulins G (IgG), which appear at the end of the disease and persist as memory against its possible return.

** Methodology: A blood draw is required, but a small amount is sufficient. “These tests are similar, over distances, to the tests carried out to find out the blood group ·, explains López. As in the antigen tests, a band will be colored if these antibodies are detected.

** Weather: 10 to 15 minutes.

** Reliability: This test does not indicate if there is infection at the moment and, in addition, it should take 6 to 8 days to develop the first antibodies against the disease in blood. That is, it can reveal whether the person has been exposed to the virus, but not whether they are still infected. “It is very useful for epidemiological studies or to find out, for example, which healthcare providers have already passed the disease and are therefore immune to it.”

** Professionals: Staff specialized in blood draws.

** Availability: These tests are already marketed around the world, but in Spain the pandemic will wait for it to evolve, since as explained by the director of the Health Alert and Emergency Coordination Center of the Ministry of Health, Fernando Simón, will be very useful afterwards, to know the true extent of the disease (to know what percentage of the disease has passed COVID-19 and, therefore, is immune). In addition, they can be used for possible new outbreaks and, in the short term, to make decisions such as when to lower containment measures, for example.


** Functioning: “It is a biosensor with a microchip about 3 centimeters long that contains multiple ‘waveguides’, where light from a laser is traveled. Viral antigens are immobilized on these waveguides. Thus, when the patient’s sample is passed through the chip, if it contains SARS-CoV-2, the virus will be captured by the antibodies and this causes changes in the properties of the light, “he explains. Maria Soler, PostDoctoral researcher at the ICN2 Group, in charge of developing this technology.

** Methodology: “It is a system similar to the devices that diabetics use to measure their blood sugar level,” he previously pointed out to ABC. Laura Lettuce, Research Professor at the CSIC and leader of the ICN2 Nanobiosensors and Bioanalytical Applications Group, as well as being responsible for the project.

** Weather: 30 minutes to find out if the patient is infected with coronavirus and another 30 minutes to confirm the diagnosis.

** Reliability: Still in testing. But when it is ready, this technology is expected to be able to diagnose not only coronaviruses, but also a common flu.

** Professionals: “It is not designed for home use, but it could be used in health centers or hospitals, without the need for highly specialized personnel,” says Soler.

** Availability: It is one of the investigations approved by the European Commission to tackle the Covid-19 health emergency. However, there is still time to use this new test: this team hopes to have the first prototypes for next year’s winter campaign. And it is expected to be able to develop a second prototype that will detect viral RNA, just like the RT-PCR tests.


Church of Fort Worth, offices closed for the week as positive presumptive chief pastor test for Coronavirus – NBC 5 Dallas-Fort Worth

The Trinity Episcopal Church in Fort Worth closed its building and offices for the week after a member of their church leadership tested the supposed positive for COVID-19.

Robert Pace, 53, remains in hospital in solitary confinement, church leaders confirmed Wednesday. According to Rev. Janet Wagoner with the episcopal diocese of Fort Worth, Pace has been part of the Fort Worth congregation since December.

“His spirit is strong. He is cheerful,
fun loving and deeply spiritual man who takes care of people like you don’t
to believe. People give it back, of course, “Rev. Wagoner told NBC 5.” I think our faith communities are uniquely equipped for
come around people and support people when this kind of thing happens and us
we are honored to have this type of role in our community where we have
networks and support systems. “

Pace is the first alleged positive case in Tarrant County. After initial discussions with public health officials this week, church officials said the rest of the congregation is not at risk.

According to the episcopal diocese of Fort Worth, Pace
participated in the consortium of gifted episcopal parishes (CEEP) in its annual
conference in Louisville, Kentucky, February 19 to February 22.

In a letter posted on the church’s website, Pace said he started feeling bad around Ash on Wednesday night.

“The beginning of Lent for me was one for the record books. I
I “involuntarily” fasted for days and days, and I certainly did
I said intercessory prayers. All this because I had a virus
that some time has come around the evening of Ash Wednesday. With high fever, a
horrible, painful cough and a little nausea, this was humiliating. But I am
finally getting better, ”said the letter.

Katie Sherrod, communications director for the episcopal diocese of Fort Worth, said she was informed by the public
Health officials that Pace’s presence at Ash Wednesday church services
the premises were not a concern, because it was then asymptomatic.

Pace tested negative for the flu twice a day after Ash Wednesday. The next time he was in church premises, on Wednesday, March 4, for a Lenten program.

“That particular night program, that is when he was here –
this is what Tarrant County public health focuses on, ”Church said
communications director Sarah Martinez. “Basically they just want to achieve
to the people who were at that event and what I was told is that they simply are
reach out and ask people to monitor their health. “

At NBC 5 all the hard surfaces in the Pace offices are told and the commonly touched surfaces were swept away after the March 4 event – along with the music stand, microphone, chair and piano bench. His exposure to anyone within a meter of him was also very limited, say church leaders.

Martinez told NBC 5 that no public health official was entrusted with the decision to cancel Sunday services this week. It was a decision by church leaders over an abundance of caution, he said.

Crews are already cleaning the church and offices day and night on alternate days. There is also a hand sanitizer available, along with many areas for hand washing.

“The public health people of Tarrant County were fantastic – they phoned me for a very long and detailed conversation, which put many worries at ease,” he said, referring to a Tuesday night conversation. “[They] they told me, there is no reason for any kind of deep cleaning, sanitizing of the church premises “.

The church
it was a polling place on Super Tuesday, particularly in its Parish Hall. On the
on election day, Pace had not been in the church building or office for
five days. Election officials provided tables, chairs and election materials
– not the church.

Next door
the church building is a nursery school, which is on vacation this week. Diocese
officials say that none of the children had any exposure to Pace.

Rev. Wagoner
says Pace’s wife, Rev. Dr. Jill Walters, tested negative for COVID-19, but
will remain in self-quarantine at home for 14 days. He encouraged people
who may know individuals currently isolated or self-quarantined to reach
via SMS or phone call, if possible, so they didn’t feel alone.

“This is a time when we really need the community and the information
and speaking of information, we really have to make sure we share it well
information including material from the public health department and the CDC “,
Wagoner said.

The Lenten program scheduled for Wednesday evening has been canceled.

Florida Mothers United in Tragedy pushes lawmakers to act – NBC 6 South Florida

For months Laurie Giordano had been telling her son’s story to anyone who wanted to hear – about how his self-styled 16-year-old Zach, should never have collapsed in the scorching heat of Florida nearly three years ago. He died days later.

For weeks Giordano drove six hours each to meet the legislators of the Capitol to push them to act, to understand the unbearable pain of a parent who was trying to make sense of the death of a child.

At Florida’s Capitol in Tallahassee, Giordano crossed paths on Thursday with Lori Alhadeff, who lost 14-year-old daughter Alyssa while filming the Parkland school. Both talked about how the tragedy and loss are motivating them to put pressure on legislation to save other children and parents from suffering.

Giordano and Alhadeff are connected for their grief over the loss of children and work to convince lawmakers to make schools safer, albeit in different ways.

Alhadeff has returned to urge lawmakers to request panic buttons in schools for faster help. This was one of the many school security measures generated by the shootings of February 14, 2018, at Marjory Stoneman Douglas High School which killed 17. The bill, known as “Alyssa’s Law”, requires that every school campus elementary, middle and high schools both public, including charter schools, to establish a mobile system to alert authorities of emergencies.

And Giordano was back on Capitol Hill sitting in the public gallery that overlooked the floor of the Senate, where lawmakers unanimously approved a bill renamed “Zachary Martin Act”. The legislation would require public schools across Florida to do more to prevent heat-related injuries and deaths.

For a few minutes, they talked about their children and their shared mission. Giordano admired the pendant hanging on Alhadeff’s neck that bears Alyssa’s smiling face.

“I don’t know how it all happened in your tragedy, but I kept thinking that help was coming,” Alhadeff told Jordan on that fateful day in February 2018.

“And help wasn’t coming,” Giordano interrupted, finishing Alhadeff’s thought.

Another distressed Florida mother, Denise Williams, wandered the Capitol on Thursday to begin lobbying for a new law on behalf of her daughter Terissa Gautney, who died on a school bus in 2018.

Ever since they lost their daughter, Williams and her husband have pushed school boards and sought the help of lawmakers to request lifesaving training for school bus drivers and better communication equipment on school buses.

He drove 250 miles (400 kilometers) from his home in Clearwater to the Capitol, describing the trip as a decision sprinkles of the moment. She sat down to watch the Senate and the Chamber conduct business, and did everything she could to plan her next steps towards making change.

“I came here to see what I could have done,” said Williams.

Williams would later cross paths with Alhadeff on Capitol Hill. He said he wanted to learn from Alhadeff, who is now a member of the Broward County school board.

“Our children have been lost in a traumatic situation and my heart breaks for any other mother. And I can feel the pain they feel, “said Alhadeff of Williams and Jordan.” Even if it involved different types of tragedies, it is still the pain of losing a child. “

Giordano’s son died in the summer of 2017 after collapsing in the Florida heat during rehearsals.

After the death of his son, Giordano founded the Zach Martin Memorial Foundation, which worked to raise awareness of the dangers of heat-related stress. As part of its work, the foundation donated 40 cooling tanks to schools across Florida.

His son, he said, would still be alive if life-saving equipment were on the sidelines during rehearsals – perhaps a tub full of water – to immediately cool his body.

“I’m exhausted, but it’s okay. Once this is over, I’m going to collapse for a week, “said Giordano waiting for lawmakers to take action on his bill.

“A six-hour trip is a long time to be alone with your thoughts,” he said, “that’s when emotions are really difficult. That’s when tears flow.”

If approved by the legislature and signed by Governor Ron DeSantis, public schools should have a tub or other large container filled with cold water on the sidelines during all games and practices. Schools should also have defibrillators to revive affected athletes. The proposed law would also require schools to train staff on how to recognize signs of heat-related ailments, including potentially fatal heatstrokes, and to take life-saving actions.

But even on the verge of success, Giordano said there is little comfort.

“I still cry every day,” he said. “There is no consolation. No, it doesn’t improve. “


The New York State plastic bag ban goes into effect – NBC New York

What to know

  • The ban on plastic bags in New York has officially entered into force, but the state will wait until April 1 to penalize stores that violate it.
  • Disposable paper bags will still be allowed, but counties have the option of imposing a 5-cent fee
  • The New York ban exempts bags used for takeaway food from the restaurant, plastic bags used to wrap meat, and bags used for prepared food.

The ban on plastic bags in New York has officially entered into force, but the state will wait until April 1 to penalize stores that violate it.

The state began banning stores from distributing most thin plastic bags on Sunday. But State Environmental Conservation Department commissioner Basil Seggos said on Friday that New York had agreed to delay execution while fighting an Albany County court case filed by a plastic bag maker and convenience store owners who define the unconstitutional ban.

An association of 6,000 convenience store owners across the state opposes state efforts to allow stores to distribute only thick, reusable plastic bags that the industry claims cannot yet produce.

“Since the beginning of our awareness campaign we have consistently said that we will focus on education rather than application and today this does not change,” said Seggos.

The state planned to enforce the ban by issuing a notice to dealers who violate the law for the first time. Resellers could eventually face a $ 250 fine for a subsequent violation and a $ 500 fine for violations in the same calendar year.

The New York ban has also attracted criticism from environmental groups who don’t want New York to allow plastic bags at all.

The law passed last April prohibits many types of businesses from using the thin plastic bags that have clogged landfills, caught in trees and accumulated in lakes and seas. Disposable paper bags will still be allowed, but counties have the option of imposing a 5-cent fee.

The New York ban exempts bags used for takeaway food from the restaurant, plastic bags used to wrap meat, and bags used for prepared food.

Environmental state officials are encouraging New Yorkers to start using reusable bags often made of canvas or polyester. The state said it had purchased over a quarter of a million reusable bags to distribute pantries and food shelters.


Some criminals who faced deportation to Illinois communities: Sheriffs – NBC Chicago

The Illinois Sheriffs Association said Tuesday that some violent criminals who had to deport are instead released into local communities after their prison terms end following a policy change by the government administration J. Pritzker.

Sheriff Mike Downey of Kankakee County and Tony Childress of Livingston County, representing the state police group, told Capitol reporters that the Illinois Corrections Department has stopped coordinating the transfer to American immigration and the United States. application of the customs of released detainees who are in the country illegally. Downey said it is similar to giving ex-convicts an “advantage to circumvent federal law.”

“It is alarming to think that due to a change in politics that suddenly these types of people might walk the streets and we might not even be aware of it,” said Senator Jason Barickman of Bloomington, one of several GOP lawmakers to sign a letter seeking legislative hearings. “We are here first of all to ask the administration to reverse this reckless policy and guarantee its safety to the public.”

But an immigration expert said the practice violates the state Trust Act, the 2017 law that restricts local law enforcement cooperation with federal immigration officials.

The sheriffs’ concerns came a few days after the Trump administration announced the unusual step of sending customs and border patrol agents to internal premises such as Chicago and other “sanctuary cities” that hampered customs enforcement.

Pritzker spokeswoman Jordan Abudayyeh called the policy change a “pause” in Corrections’ interactions with ICE, while Pritzker staff examine it and other procedures.

“The governor made it abundantly clear that Illinois will be a firewall against the president’s attacks on immigrant communities,” said Abudayyeh.

Downey said corrections officials announced late last month that they were canceling a trial whereby criminals who lived illegally in the country, with their expiration date, were being transferred to the Pontiac Correction Center. It is there that, since October 2016, Kankakee County Sheriff’s deputies collected and detained them under contract with ICE.

Of the 223 immigrants transferred from Pontiac to ICE detention in 2019, Downey said 11 were convicted of murder or attempted murder, more than four dozen predatory criminal assault or sexual abuse, including crimes involving children, and 33 were convicted of a crime involving a weapon.

Robert Guadian, director of the Chicago field office for ICE enforcement and removal operations, said in a statement that Illinois “puts politics ahead of public safety” when it breaks the communication between Corrections and ICE. It has increased the average total of affected prisoners.

“Now, around 400 convicted criminals per year – including criminals who have served time for crimes such as child sexual abuse and murder, will be released in your community and mine,” said Guadian. “I can’t think of any other state that protects convicted criminals …. ICE will now have to make these arrests in the community when they should have been made within the safe borders of a prison.”

Mayor Lori Lightfoot joined the protesters who gathered outside a press conference involving the “imposition and removal” operations of the new Chicago local office of the United States Immigration and Customs Enforcement (ICE).

Fred Tsao, senior political consultant for the Illinois Coalition for Immigrant and Refugee Rights, said that the Trust Act, signed in August 2017 by Republican Governor Bruce Rauner, prohibits the collaboration of IDOC and Kankakee County with ICE, although the ICE holds a warrant or so-called federal immigration holder on the person.

“The IDOC would not be able to detain anyone beyond that person’s end of the criminal sentence even if that person were subject to an ICE detainee or warrant,” Tsao said. “In no event would Trust allow any sheriff or local police department to take custody of someone based solely on an ICE holder or mandate.”

The Trust Act allows local police to communicate with immigration agents and to detain someone for federal authorities if a valid criminal warrant exists.

In this case convictions should count, said Quincy Republican Senator Jil Tracy.

“These are convicted criminals,” said Tracy. “They served their sentences. However, will they register with a probation officer? “

Regarding the perpetrators of sexual offenses, Childress added: “People who do not have a legal status in this country do not register in the Illinois Sex Offender Registry. And if they flee Illinois, they don’t register anywhere else. “
