آسیب های رایج مربوط به نوار تیپ :


عوامل متعددی در آسیب رساندن به نوارهای ابیاری قطره ای و پلی اتیلن تاثیرگذارند. تجهیزات نصب و راه اندازی، تجهیزات خاکورزی، حشرات، پرندگان، جوندگان، آسیبدیدگی از طریق اعمال فشار بیش از حد یا پدیدۀ ذره بینی نور خورشید زمانیکه به قطعات آب موجود بر روی پلاستیک شفاف بر خورد می کند از آن دسته اند. تجهیزات تزریق نوار باید به طور منظم مورد بازبینی قرار گیرند، و سیستم آبیاری قطره ای باید بطور منظم بررسی شود و در صورت مشاهدۀ گودال کوچک آب، فواره های کوچک، کم شدن فشار یا محصول مواردی که محتمل آسیب دیدگی می باشند شناسایی گردد. به محض مشاهده چنین مواردی به منظور جلوگیری از مشکلات آتی باید نسبت به کنترل و مدیریت آفات یا تنظیم تجهیزات اقدام شود. تصاویر زیر رایج ترین عوامل آسیب دیدگی تیپ را نمایان می سازد. توجه داشته باشید در سیستم SDI پدیدۀ ذره بینی نور خورشید پدیده ای نادر است چرا که معمولا نوار های آبیاری زیر خاک نصب می شوند و در معرض اشعۀ خورشید قرار ندارند. در عوض این سیستم در معرض آسیب جوندگان است.

    Vanuatu has begun a week-long state of emergency and a clean-up
    that will take far longer, following an earthquake that has killed at least 14 people.



    Rescue efforts are underway from Tuesday's 7.3 magnitude tremor, with infrastructure and communication breakdowns still hampering a full assessment of damage.


    In the capital Port Vila, which was shaken violently for 30 seconds in the Pacific nation's strongest earthquake this century,
    there is destruction.

    Katie Greenwood, the Red Cross' Pacific head, said the Vanuatu government confirmed a death toll of 14 and at least
    200 injuries. 


    Vanuatu Government is reporting 14 confirmed fatalities and 200 treated for injuries at main hospital in Port Vila.
    Local humanitarian network activated and @vanuaturedcross leads the Shelter response with Government
    and support from @ifrc

    - Katie Greenwood (@KatiegIFRC) December 17, 2024

    Australians are not among the dead, according to Deputy Prime
    Minister Richard Marles, although some have been injured.


    "There are, you know, small scrapes and the like which are being handled," he told ABC News.


    Reuters has reported that two Chinese nationals have been killed.


    AAP can confirm another is a 26-year-old woman who had finished a nine-month stint as a seasonal
    worker in Queensland to head home for Christmas, identified by
    her former boss as Valerie.

    "It's tragedy. Twenty-six years of age, a single mother only went home three days ago. It's an absolute tragedy and our team's been really rattled by it," Icomply
    chief executive Rodney Prestia told AAP.

    Broadcaster VBTC and social media media users have shown collapsed buildings in the capital, large cracks in roads and landslips which have cut off key routes.



    Vanuatu Police Commissioner Robson Iavro said there were
    three people trapped in a Port Vila building.

    "We believe there are more stuck inside," Mr Iavro said.

    A diplomatic hub housing the US, UK, French and New Zealand
    diplomatic posts has partially collapsed, but all nations have reported
    their staff to be safe.

    "Many victims in the country, flights suspended, communications cut, no water or electricity, we are organising relief,"
    French ambassador to Vanuatu and Solomon Islands, Jean-Baptiste Jeangene Vilmer, posted on social media.

    Caretaker Prime Minister Charlot Salwai issued a state of emergency for seven days, and instituted an overnight curfew - except for essential services - from 6pm to
    6am.

    Those communicating with the outside world were largely able to do so through Starlink, including long-term Vanuatu journalist
    Dan McGarry.

    Mr McGarry was the first to report loss of life
    from Port Vila, fearing a "mass casualty event".



    "People died and many more were hurt. Some have lost their home, and many will find it hard to get back to work. Repairs will likely stretch for years, as they always do in the wake of disaster," Mr McGarry posted on X.


    "But people are pulling together as only Vanuatu knows how. We will get through this. We always do."

    Power and water was gradually being restored through
    the capital on Wednesday.

    Vannuatu is made up of more than 80 islands, and it is unclear how
    the 350,000-strong population is faring in towns and settlements
    outside Port Vila.

    Australia sent planes to survey the damage in the morning,
    and were due to bring relief later in the day,
    as well as medical and urban search and rescue teams.



    Australian Foreign Minister Penny Wong called the disaster a "dreadful tragedy" and with acting
    Pacific Minister Matt Keogh, said Australia
    would be rushing to its neighbour's aid.


    Australians are thinking of our friends and neighbours in Vanuatu after the devastating earthquake that struck their home
    this afternoon. We are closely monitoring the situation and stand ready to assist the
    people of Vanuatu in any way we can.

    - Anthony Albanese (@AlboMP) December 17, 2024

    Mr Jeangene Vilmer said France had brought a military helicopter from nearby New Caledonia with communications and
    engineering support, and was working with Australia and New Zealand to co-ordinate the
    response. 

    The disaster has occurred at a moment of political turmoil
    in the Melanesian nation.

    Mr Salwai dissolved parliament last month, setting the stage for a snap election on January 14, only for
    opposition MPs to mount a constitutional challenge to the move.


    While a first case was dismissed by the Supreme Court last week, former prime minister Ishmael Kalsakau
    announced they are appealing that judgment - which
    was due to be heard before Christmas.

    If full skirts and punchy prints aren't your mother's go-to, strive a press release sleeve.
