There is an old idea: there is no difference in multitasking, that is, they are able to pay attention to several tasks at the same time.For decades, the notion that women were much more effective in focusing on more than one job at a time was holding back. According to a 2015 survey, for example, about 80 percent of voters said that men were much weaker in this area. However, according to a new study, there is no significant difference between the two,I do not determine if one can look at the other person whether it is male or female.Women can't pay attention to more than one thing at a timeMultitasking is described by professionals as when we focus on more than one task at a time. It takes our minds better because "there is an overlap between the cognitive processes that are responsible for the execution of each task". Many people think that multitasking is more effective than just concentrating on one task, but that is not true, because the brain really has to "jump" from one task to the other, and it also has an effect on attention and concentration.Patricia Hirsch, a researcher at the University of Aachen Psychological Institute and his team investigated whether there could be any scientific basis for this finding. A total of 96 people, 48 men and 48 women were enrolled in the study, who had to pass two tests. One task had to move quickly from one task to the other, and the other to concentrate on two tasks at once. Between tests, the response time and accuracy were measured. It turned out that if the participants try to focus on two tasks at once (one at a time, one after the other), reaction time and accuracy are also reduced, regardless of whether the subject was male or female.The results of the research were reported in the PLOS One Company professional journal.

Trophoblast biopsy is the newest technique for taking cells from the uterus of a pregnant woman into placental tissue for examination of the embryo.
In other words, you can find out how healthy your little one will still be from the stage when he or she is barely formed.
The trophoblast biopsy or the removal of chorionic villi allows the detection of genetic or metabolic diseases such as Down syndrome, Trisomy 21, Turner syndrome, hemophilia or myopathy from the prenatal phase.
The intervention is performed in the tenth week of absence of menstrual flow and is performed vaginally (insert a penis through the cervix to the trophoblast) or abdominal (puncturing the wall of the abdomen).
The biopsy lasts between 5 and 15 minutes, under the control of the ultrasound, and the pregnant woman must drink half a liter of water an hour before to reveal the vision. The investigation is not routine, as it presents a spontaneous miscarriage.
What's really going on?
As an embryo develops, it is constantly divided. In the case of healthy embryos, from the fifth week after fertilization they are divided into about 100 cells that form a large sphere filled with liquid.
At this stage, the embryo is called "blastocyst", composed of two types of cells: those in the lower mass will soon form the fetus, while those contained in the sphere are called "trophoblast cells".
The latter will constitute the placenta and other tissues on which the good development of the fetus depends. The advantage of trophoblast biopsy is that the cells can be taken without the embryo being damaged, and the procedure confers a good amount of genetic information. Below you can see the cells in the examination process.
A small hole made in the tissue surrounding the embryo allows the trophoblast cells to penetrate the outside:
The trophoblast cells are then aspirated into a pipette:
The string of cells that form between the pipette and the sphere and is "interrupted" using the laser technique:
Can you find out the sex of the child?
As surprising as it may seem, trophoblast biopsy can even tell you the sex of the future fetus, even from the earliest stage of pregnancy.
This is possible because the entire procedure is based on a fetal karyotype, ie a photograph of the chromosomes of the embryo, which should be 46 in number arranged in 23 pairs.
The last pair of chromosomes determines the sex of the baby: if there are two X chromosomes, then you will have a baby girl. If an X and a Y chromosome are identified, then the embryo will develop into a boy.
The sex of the child is important to know, not only for satisfying a natural curiosity, but also in case of possible transmission of a sex-related disease.
The trophoblast biopsy also provides as much data as is obtained from amniocentesis, but much earlier in terms of age of pregnancy.
The disadvantages of trophoblast biopsy refer to the time period needed to interpret the results, that is, between 12 and 24 hours. If we talk about an unfortunate case in which the embryo is ill, a late intervention could mean less chance of remediation.
In addition, there were 1% cases in which false-positive results were obtained, due to the phenomenon of placental mosaicism: some of the harvested cells are genetically abnormal, although the chromosome status of the fetus is normal. In this situation, amniocentesis can confirm or deny the diagnosis.
Who needs to perform a trophoblast biopsy?
This investigation is recommended for pregnant women who are at increased risk for a difficult pregnancy, such as:
- spontaneous abortions recorded in the past without a clear cause;
- chromosome-type genetic diseases;
- parents or close relatives with genetic abnormalities;
- pregnant women over 35 years of age;
- women who have given birth to children with congenital malformations.

Choosing well. 5 steps to success
The decision of parents to choose a good one for their child is not at all easy and accompanied by stress. It is not easy to entrust the most important person in your life to a foreigner. Parents will now be in a permanent state of alert and will have to constantly evaluate the qualities of the bone.
1. Be very attentive to the boss who does not have or refuses to provide a list of references. It may be a sign that he is trying to hide an unpleasant past experience.
2. During the interview, pay attention to the signs that may indicate the baby's inability to care for a child. An alarm signal may be that the nurse recognizes that she has not taken care of several children at once (if you have 2 or more children you want to take care of) or that she has not taken care of children the age of your child.
Lack of experience is an important point to take into account.
3. Follow the behavior of your child when you come home after staying with the nanny.
If the child gives signs of anxiety when he / she should be left with the baby, it may be a signal that something is wrong. Use your reasoning well in this case and try to differentiate a possible problem from a possible theatrical act of the child.
4. Pay attention to topics addressed by the nanny before and after staying with your child. A good capable person will ask for special instructions before you stay with the child and will tell you in detail what happened while you were away. If the nanny simply takes her money and leaves, it may be a signal that she is not interested in your child's development.
5. Keep an eye on the clock. If your mother is late, it may be a sign that she is not paying for time or her job, which may mean she is doing the job of salvation when she is watching over your child.

The pear compote can be prepared for immediate consumption as well as to be stored in the room, along with other preserves.
2 kg pear
0.5 kg old
1 vanilla stick
Method of preparation
Choose autumn pears, from aromatic varieties. Wash the fruits and clean the peel. In order not to turn dark, as it is cleaned, put in a bowl of cold water, with a little lemon juice added.
The cleaned fruits are cut into quarters, then the seed box is removed. If you like, you can leave the pears in this shape or you can cut them into cubes.
Put the slices of pears in a large bowl and pour over them a boiling syrup, prepared from half a kilogram of sugar and a liter of water. Cover the bowl and allow it to cool.
Repeat the same operation again until the pears soften, then put the fruit in jars, pouring the syrup over them.
Fill with water, if necessary, for the fruit to be well covered. Add to each vanilla jar or lemon peel. Close the jars and sterilize them.
