windy city rainy season

Chen Li's report talked about the degradation model of thiamine compounds in biosolids and the influence of external environmental factors on the degradation rate. This article was published in a journal with a high impact factor in the United States a few months ago.Tao Yu had heard his report when he attended the exchange meeting in Shanghai. At that time, the audience was professors, so the content focused on the practical application of the model. Now when he talks to students, he focuses on the basic theory and the process of building the model.

Chen Li is very good at mastering the rhythm of the speech, trying to avoid singing a one-man show by himself. He asked the students their thoughts on the experimental design, asked them to guess the experimental results, and proved whether the guess was correct through data analysis, and then gave the theoretical basis. The 45-minute report presented It is not just a conclusion, but a complete research process.In all fairness, Tao Yu felt that the effect of Chen Li's scientific research report was very good, and even Luo Feng, who had to sleep in every lecture, persisted until the end.

"Thank you for coming..." The slide turned to the last page, and the people on the podium thanked, "especially those of you who did not check your phone once."

There were snickers in the auditorium, and some people put away their phones in embarrassment.Tao Yu applauded along with the others, and then it was time for free questions. He walked up to the old Andrew in the front row and asked in a low voice: "Professor, you didn't tell me Lee was the speaker of this week! When did you invite him?" (Translation: Professor, you didn't tell me that Chen Li was this Zhou's invited speaker, when did you invite him?)

The old man spread his hands and said: "Ididn't. HeisProfessorGruca'sguest. IpassedthemessagetohimwhenwewereinShanghai.Hesaidhewouldthinkaboutbutdidn'tsayyesrightaway.I'mgladeventuallyhedecidedtocome.Thisisagoodpresentation, isn'tit?" Professor Ruca's guest. When I was in Shanghai, I just Brought the news, he said he would consider it but didn't say yes right away. I'm glad he decided to come anyway, it was a nice presentation, wasn't it?)

Professor Gruca is the young professor in the department, and he is also the most likely candidate to succeed the director of the environment major after the old Andrew retires.Although Chen Li was engaged in environmental statistics and risk analysis after doing a doctorate with the old man, after returning to China to teach, his personal research direction has become more and more biased towards his original chemical engineering major, which coincides with Gruca, which is also engaged in pollution treatment technology.

"Itis." Tao Yu looked at Chen Li who was answering students' questions on the podium and said, "...and it was a big surprise of seeing him again..."

"I'mafraid your surprise may last longer." said old Andrew. Two-year project funded by Cook County Government to develop treatment technologies for Class B biosolids.)

"Youkidding?!"

"Why would I?" the old man asked back, "Don't you know he has a patent of biosolids treatment tower technology? Leeis smart guy and very good at moving idea patent." Good at converting research into patented technology.)

"... so he will be working here a visiting researcher in the next two years?" Tao Yu glanced at the stage again in disbelief. (Translation: So he will be a visiting scholar here for two years?)

"You know very soon I'm going to tire." The old man explained, "The department has been looking for a new professor for awhile. Leeisagood candidate. Hecanteachmyclassesandheisamatureresearcher. Retired, the department is looking for a new professor. Chen Li is a good candidate, He can teach my class and is a full-fledged researcher himself. That two-year program will be a transition phase, taking him from a visitor to a full-time professor here.)

"Asatenure?" (Translation: As a tenured professor?)

"Well, afull-time doesn'tnecessarily meant tenure, but I think our department will eventually hirehimasatenure."

Tao Yu's mood is very complicated. On the one hand, he is happy that the department recognizes his brother's achievements, and he also hopes to have more opportunities to work with Chen Li. When he was in Shanghai, the other party gave him some good advice. Help yourself more.On the other hand, he felt uneasy. After glancing at the other party's possible intentions, he didn't know what attitude he should take to face it.

"Lastquestion..." Professor Gruca presided over the report as the person who invited Chen Li, and the last question was left to the professor on site as usual.

"Professor Chen, you know where we have very strict requirements on biosolids applications. No offense, but what I learned is that China is about 30 years behind the US in rule making and den forcement. Chinese farmers still use human-faces-based fertilizer, which has raised leads and heavy metals contamination problems. H owcan you prove the technique that fits in China would not be there" (Translation: Professor Chen, you know there are very strict regulations on the application of biosolids here. No offense, but as far as I know China is in (In this regard) the formulation and implementation of regulations is 30 years behind the United States, and Chinese farmers are still using human excrement as fertilizer, causing lead and heavy metal pollution problems. How can you prove that this technology that is applicable to China is also applicable here?)

The venue was silent for two seconds, and everyone could hear the sharpness and disdain for developing countries in this question.The report made by Chen Li is not directly related to excrement. Biosolids refers to the solid sludge after sewage treatment. In the United States, this kind of sludge is divided into two types: A and B. Those containing pathogens and heavy metals that meet the standards can be used as farmland fertilizers, while Type B is not up to the standard, and it is also the object of Gruca's invitation to Chen Li to cooperate in the research.Indiscriminate use of sludge as fertilizer does exist in China. However, this has nothing to do with Chen Li's report. His model is used to optimize the ratio of ammonium sulfate in the process of sludge treatment to achieve the maximum utilization of nutrients.

Tao Yu turned to look at the person who asked the question. He was a professor of civil engineering in the department, and he didn't have much contact with him.It is true that we sometimes encounter such situations in foreign countries. In fact, most Americans do not have a xenophobic mentality. After all, this is a country of immigrants. Everyone in the previous generations is a foreigner, but some people always like to think highly of themselves, even if Others didn't see any advanced places in him.

"Whata Canadian Jerk!" Old Andrew murmured in dissatisfaction. As the head of the environmental profession, he was about to get up and play the role of peacemaker. Chen Li on the stage smiled and said:

"Back to30yearsagowhen Iwasinelementaryschool, IwastaughtthatChinawas100yearsbehindAmerica. At that time, I heard that China was 50 years behind the United States, and then I heard that it was 30 years, 12 years...but when I had an interesting discovery when I first came to the United States. It turns out that China is twelve hours ahead of the United States. Note: time difference.)

There was laughter in the venue, and Chen Li continued: "Chinese farmers have been utilizing human-feces-based fertilizer for thousands of years. That'sone big reason that China still has fertile land after planting so many years. Heavy metal contamination is not attributed to using feces fertilizer, but the inappropriate disposal fin industrial waste, including the waste from developed countries. Decontamination of heavy metals in soils and biosolids is our next step to deal with." An important reason why China's land remains fertile after being cultivated for thousands of years. Heavy metal pollution cannot be attributed to the use of such fertilizers, but to improper disposal of industrial waste, including waste exported from developed countries. Solving soil and biological Heavy metal pollution in solids is our next step to solve.)

Without leaving any opportunity for supplementary questions, Professor Gruca got up to thank Chen Li for his report on behalf of the department, and announced that Professor Chen would cooperate with him to study the treatment technology of Class B biosolids.

Old Andrew turned his head and said to Tao Yu while applauding: "It old you heis as smart guy, evens smarter than I thought!" (Translation: I said he was a smart man, smarter than I thought.)

Tao Yu agrees with the old man's statement. Chen Li can neither affirm nor deny the professor's question. He uses another way to convey the fact that the gap between China and the United States has shortened rapidly in the past few decades. Pollution stand.Changing positions, Tao Yu wondered if he could answer this embarrassing question without embarrassing both parties.

After the report, Gruca introduced Chen Li to the head of the department, and Andrew Sr. and another environmental professor also joined in the conversation.Seeing that the other party couldn't get out for a while, Tao Yu sent him a private message on Weibo, without leaving a message, just a thumbs up sign, and then left the venue with other students.

Half an hour later, Chen Li wrote back: I will contact you later.

After class in the evening, Tao Yu checked Weibo, but did not receive any news. He put his phone back in his pocket and laughed at himself secretly. What was he expecting?

On the way home, I received a call from Chang Zheng, saying that there was a car accident on Hubin Road when I got off work, and the hospital received several wounded people who had just been treated and were now preparing to go home.Just hung up here, another call came in, and the caller ID was Tang Hainan.Tao Yu pressed the call in bewilderment. Ever since Teacher Tang's family added a little princess half a year ago, he has been busy posting about the child on Weibo, and has not cared about himself for a long time.

"Tao Yu, do you have time to come to BOG?"

Tao Yu couldn't help laughing and said, "Teacher Tang, you've been confinement for half a year, so you're done?"

Tang Hainan didn't prepare a strong counterattack for a long time, and hung up the phone after saying "Get over here quickly".

Tao Yu put away the phone with a smile, and turned back to school. BOG is a student activity center, with entertainment facilities such as bowling and billiards, and a small bar. ID card is checked before entering the door. Those who are 21 years old will be given a green bracelet, indicating that they are old enough to buy alcohol.

As soon as Tao Yu entered the bar, he saw Mr. Tang at a table in the back, and the one sitting opposite him with his back to him was Chen Li.Tao Yu was not surprised that these two people knew each other. They were the same year. Tang Hainan had been teaching in this school for almost ten years. They met when they wanted to come to Chen Li as a postdoctoral fellow.

He ordered a bottle of beer at the bar, made a phone call while standing at the door, and walked towards the two of them.
