DIFFERENT TYPES OF FIBRE

-
STEEL FIBRES
Steel fibres available for use in concrete are obtained by cutting drawn wires. Fibres with different types of shapes such as round, rectangle, intended, crimped etc.

PLASTIC FIBRES
Plastic fibres such as nylon and polypropylene has high tensile strength and low modulus of elasticity. It has the advantage of chemical stability in the cement paste and not attackedby acids and alkalies

CARBON FIBRES
Carbon fibres has high tensile strength and youngs modulus compare to steel and glass fibres . Carbon fibres has greater stability , The carbon reinforced cement composite has linear stress strain characteristics. These are costly.

COIR FIBRES
Coir is the fibrous portion of coconut, extracted mainly from green nut. Coir fibre is tough and strong and has a greater resistance to fungal and bacterial decomposition.

GLASS FIBRES
These are 2-3 times stronger than steel fibres. These fibres does not deteriotate by insects or chemical attack. These are moisture resistant, they repel water and readily dried.

MINOR DISORDERS OF NEW BORN AND ITS MANAGEMENT - NURSING ASSIGNMENT

-
INTRODUCTION         Neonatal health problems are frequently found ranging from minor physical or physiological peculiarities to the serious life threatening illnesses. Minor problems should not be ignored lightly without adequate assessment of the conditions. Early diagnosis and management of the serious problems help to overcome life long disability and to reduce neonatal morbidity and mortality. Nurses are responsible to manage the minor problems and to detect the serious problems for early and prompt management along with appropriate nursing interventions and support to the mother. MINOR DISORDERS OF NEW BORN 1. VOMITING         Vomiting is one of the common manifestations in the neonates. Regurgitation after feeds should not be confused with vomiting. Mucus vomiting often hinged with blood is quite common soon after birth. It is due to irritation often gastric mucosa by the swallowed materials during birth. Causes: ·         Dietic ·         Over feeding

KANGAROO CARE - NURSING ASSIGNMENT

-
INTRODUCTION         Caring low birth weight baby is a great challenge for the neonatal care unit and the family. Number of low birth weighs baby is still for beyond the expected target in our country. The cost of the quality management of these babies is increasing day by day. Kangaroo care is low cost approach for the care of low birth weight baby. This method of care was introduced and popularized by Dr.Edger Ray, Dr.Martinez and Dr.Charpak in late 1970s. DEFINITION         Kangaroo Mother Care (KMC) is a special way of caring low birth weight infants by skin to skin contact if promotes their health and welling by effective thermal control, breast feeding and bonding. KMC is initiated in hospital and continued at home. COMPONENTS OF KMC         In KMC, the infant is continuously kept in skin contact by the mother and breastfed exclusively to the utmost extent.         The two components of KMC are; 1.    Skin to skin contact is provi
