One day in early March 1993, Pauline and Tom Nichter took their 11-year-old son, Jason, to buy toys in Buena Park, California. Suddenly, Pauline sees a purse on the ground, and she picks it up and sees that it contains $200. The homeless and jobless family knew that the $200 could change their lives.

However, they took the purse they found to a nearby police station. Upon inspection, this lost wallet contained more cash, over $2,000! The police notify the owner to claim the wallet.

The owner shook their hands and thanked the Nichter family, but did not give them any honorarium. Luckily, a journalist covered their story. People all over the world heard their stories and sent them letters and belongings, and some even helped them find jobs.

One businessman even let the family live in his house for free for half a year. So far, the family has received more than $100,000 in help. Now, the Nichter family sees a bright future.

One day in early March 1993, Mr. and Mrs. Nicher (Pauline and Tom) took their 11-year-old son, Jason, to Buena Park in California to buy toys. Suddenly, Pauline sees a purse on the floor, and she opens it to see that there is $200 inside. Although the Nicher family was homeless and unemployed, and they knew that the $200 could change their lives, they went to the nearby police station and turned in their wallets, and (the police looked closely) to find that there were pockets in the wallets, and there was more money in the pockets - more than $2,000!

**Hit** Let the owner come and get the wallet back. The owner thanked the Nicher family and shook hands with them one by one, but did not give them any reward. Luckily, a TV news reporter happened to capture the story.

People all over the world learned about the story and sent them letters, money, and jobs. One businessman even allowed the Nicher family to stay in his house for free for six months. So far, the Nicher family has received more than $100,000.

Now their future is bright.

One in early March 1993, Paulina and Tom Nichter and their 11-year-old son Jason Day, was a shopping shop in Buena Park Toys, California. Suddenly, Pauline sees a purse lying on the floor. When she looked inside, she found 200 yuan.

Families, homeless, and without jobs, knowing that it could change their lives. But they put the wallet near the police station, and the wallet transferred in was found to have some other pockets, and in more money than 2000 yuan! ** Named the man who lost the wallet and picked it up.

The man thanked the nichters and shook their hands, but did not reward them. Lucky Family, a news story filmed by a TV reporter. From people hearing stories from all over the world, sending them letters, money, and even work.

A businessman even let them live in his house for 6 months free. So far, the family has received more than $100,000. Now the future of the nichters is bright.

。Clarification of possible oxidized SN2+ internal tin HEDP and SN-pei MP collaboration.

There was no variation in the NMR phosphorus spectra of the samples of T(b) with HEDP or Peggy MPs overnight, so we can assume that no Sn2+ oxide occurred. Should this already be the case, we expect to increase in the proportion, the intensity corresponding to the peak, which will eventually approach the spectrum with respect to tin(iv)-complex, at the respective pH.

In a study to understand the conditions required for the oxidation of SN2+ in the presence of HEDP, the complication is titration of hydroperoxide (30HO). The ratio of metal ligands 1:3 (pH) was selected in order to limit any uncomplicated fields to hydrolysis and precipitation in titration.

No precipitation was observed throughout the survey, and the internal 1:3 mixture was observed, even over a long period of time, which showed that all fields successfully compounded the solution neutralization changes, and the pH value does not affect the tin ions directly [tin HEDP] recombination is not stable enough to fluctuate with the station pH. mixture in which the concentration of metal ions in excess, i.e. m:

l 》 1:1 p.m., after the demonstration of immediate precipitation, sodium hydroxide was added. Precipitation eventually occurs in these solutions, even after a few hours without any pH manipulation – both Sn2+ and SN4+.

Tin oxide in [Tin(b)-HEDP]0 and [Tin(b)-Tin(iv)-Peggy]4+ systems induce an increase of 3 0 L O fh2O2, 005 ml (Figure 9) and moll (Figure 8), respectively. As expected, an increase in the intensity of the resonance of T(d) was observed in the case of HEDP, steadily decreasing in the intensity of the resonance, at about 19 ppm, using and Pegger Congressman, we observed the disappearance of the signal for T(b)chelation, although only some increase (35-45 resonance of intensity was achieved for the S4+ complex.

There is an increase in the concentration of free ligands (40-55) which may be due to the liberated ligand having been previously constrained to S N2+. At the same time, the increase in both amounts [Sn(IV)-P2+ and free ligand after oxidation means that the Peggy MP believes that the previous constraint to S2+ is evenly distributed between the SN4+ constraint and the free ligand solution. In addition, this would mean an increase in the concentration of free metal ions (i.e., at least half of the tin ions being released reflect an increase in the concentration of free ligands).

This is confirmed that after the slight precipitation occurs, the oxidation drives thereaction Sn(IV) +4OH - = Sn(OH4) ( approx. mol hydrogen peroxide mol SN2+ internal HEDP system and needs to oxidize it to achieve a pH equivalent equal to complexed SN4+ at the same pH (Figure 9) for [Sn(b)-Pelle] 0 system for reference.

These correlated structured data show that with the highest efficiency of cellular transfection efficiency with transfection to obtain reagents, easy to moisturize, form fluid aggregates, accept the transition to the inverted hexagonal stage plastid DNA (in the presence of) p-DNA physiological ionic strength.
