Response of Animals to Ultrasound

22-25 kHz: Dogs, Cats
38-44 kHz: Mosquitoes, Fleas, House Fly, Spiders, Cockroaches
52-60 kHz: Lizards
60-72 kHz: Rats

How does ultrasound repel pests?

US pest chasers are designed to repel pests from the home. Rodents respond to US with a frequency around 60 kHz. Cats and Dogs can be repelled using 22-25 kHz. Insects like mosquitoes, House fly, Fleas etc responds to 38-44 kHz. US will create high pressure on the eardrum of Rats so that they move away from US source. US generally creates stress on animals, so they avoid ultrasound.

How does Ultrasound repel Mosquitoes?

Male mosquito is the natural enemy of female mosquito after breeding. Both male and female mosquitoes use plant juice as food. But female mosquito requires human blood protein for the maturation of their eggs. Male mosquitoes will not bite human beings. On the first day of emergence, the female mosquito will not bite but after mating with male it starts to bite human beings to get blood. Female mosquito will not allow males to mate again and they avoid the presence of males. Females detect the presence of males by sensing the US produced by the males. If an US generator is used, it will imitate male mosquito by producing 38 kHz US . This will repel Female mosquitoes. Moreover the US will create stress on the US sensillae present on the antenna of female mosquitoes, so the move away from the source of US .

Kursevi nepoznatog autora

Nepoznati autor sa naših prostora, koji u ovom trenutku želi da zadrži anonimnost, nesebično deli svoje znanje na kanalu WebDevPro.

Do sad su snimljeni video serijali za OpenBSD, HTML, Python, C++, Linksys, MySQL, JavaScript, Django, PHP, Bootstrap 4, uz to i nekoliko kraćih sadržaja u istim ili povezanim kategorijama.

Svaki serijal sadrži epizode koje su na engleskom jeziku, s fokusom na određeni segment iz pomenutih oblasti, u prosečnom trajanju od pet do deset minuta. U ovom trenutku najviše materijala snimljeno je za JavaScript, Python i CSS.

Baza besplatnih materijala za razvoj digitalnih veština i znanja sve je veća. Podsećamo na 16 besplatnih MIT kurseva koje smo podelili prošlog meseca, a nešto ranije Harvardove besplatne kurseve, koji u ovom trenutku imaju više od dva miliona polaznika. Naša baza sadrži i 6 priznatih obrazovnih institucija u oblasti računarskih mreža, 450 besplatnih kurseva elitnih američkih univerziteta, 400 besplatnih udžbenika koje je otključao jedan vodeći svetski izdavač, 10 besplatnih kurseva priznatih institucija, a tu su i već čuveni kursevi Coursere.

3% hidrogen

3% Hidrogen se koristi na sledeći način:

• Prvo pravilo je da se rastvor pije najmanje 30 minuta pre jela ili pića ili dva sata nakon jela.
• Program uzimanja hidrogena traje 14 dana.
• Prvoga dana uzima se  po kap na dve-tri kašike vode (30 ml do 50 ml) triput dnevno,  drugog dana - po dve kapi, tri put dnevno, trećeg dana - po tri" i tako do 10 kapi dnevno.
• Tada se pravi pauza od dva, tri dana, a zatim se uzima po deset kapi triput dnevno, uz pauziranje na svaka dva-tri dana. Uzimanje traje mesec-dva ddana.
• Uzimanje hidrogena nema kontraindikacija, ako se uzima na prazan stomak.
• Svako treba da osluškuje reakciju svog organizma i da sam odredi sebi najpogodniju dozu.

Preserve line breaks in textarea

Generally you just need to add

• white-space: pre-line; whitespace trimmed to single whitespace or
• white-space: pre-wrap; all whitespace preserved

to the element's style (CSS), where you want your text rendered with line-breaks.

You can do:

white-space: pre-wrap;
overflow-wrap: break-word;

You keep output in textarea as it is. You would receive input as a string output that string(write to file) that string adding textarea to the input string.
for eg.
<?php
$txt = $_POST["inputstr"];
$txt1 = "<textarea>". $txt ."</textarea>";
$file = fopen("file.html","a+");
fwrite($file, $txt1);
fclose($file);
?>
