    Road sw

    eeping machines a

    re used in

    a wider application area than just road

    sweeping. Their versatility allows them to

    be used on large construction sites and

    as well as industria

    l sites where th

    e col-

    lection of debris

    is im

    portant, for both

    safety re

    asons as well as aesthetic re

    a-sons. The reason why the m

    ajority of road

    sweeping machines a

    re truck based is to

    allow for e

    xtended tim

    Concrete roofs, even with go

    -branes are easy to repair if an accident

    occurs when they rem

    re also the most practical

    waterproofing method when a decorative

    t is a remarkable s

    urvivor of an

    ancient aquatic world now

    a new study sheds light o

    n how one of E

    arth's oldest reefs

    I was formed. R

    esearchers have discovered that one of these

    reefs now

    located on dry land in Nam

    ibia w

    as built almost

    550 m

    illion years a

    go, by the first an

    imals to h

    ave h

    ard shells.

    Scientists say it was at this point that tiny aquatic creatures

    developed the ability to

    construct hard protective coats and

    build reefs to s

    helter and protect them in an

    increasingly dan-

    gerous world. They w

    ere the first animals to build structures

    similar to n

    on-livin

    g reefs, which are c

    reated through the na

    t-ural processes o

    f erosion an

    d sedim

    ent deposition. The study

    reveals that th

    e anim

    als attached th

    emselve

    faces and to each other by p

    roducing natural ce

    ment com

    tructures.

    The creatures k

    nown as Cloudina built reefs in ancient seas

    that now

    form

    part of N

    amibia. Their fossilised remains are

    the oldest re

    efs o

    f their type in the world. Cloudina were tiny,

    filter-feeding creatures that lived on th

    e seabed during the

    Ediacaran Pe

    illion years ago. Fossil
