INTRODUCTION Behind armour blunt trauma (BABT) has been defined as a non-penetrating injury caused by the rapid deformation of body armour. There has been an increasing awareness of BABT as an injury mechanism in both the military and civilian worlds; whether BABT results in serious injuries is debatable. METHOD A systematic review of the openly accessible literature was conducted using the P...

Advanced polymeric materials are finding an increasing range of industrial and defence applications. These materials have the potential to improve combat survivability, whilst reducing the cost and weight of armour systems. In this paper the results from a split Hopkinson pressure bar (SHPB) test of a high density polyethylene (HDPE) sample involving multiple stress waves is discussed with aid ...

This study follows on previous research which investigated the comfort and types of bras worn by UK female police officers when wearing body armour performing typical activities. controlled involved a cohort 31 three main areas. Firstly effect professional bra fitting size comfort, secondly an underwired or sports ability to perform certain actions, thirdly key anthropometric data in relation a...

Co-Continuous Ceramic Composites, referred to as C4, have bi-continuous, interconnected and interpenetrating phases of a metal and ceramic. This bestows such composites with a higher strength to weight ratio compared with traditional composites. In this research work, a C4 composite of AA5083/SiC is fabricated for personal body armour, using gravity infiltration technique. A numerical simulatio...

The ballistic performance of the lightweight armour systems was examined to obtain an estimate for the V50 and the global damage of the composite plates. All estimates were performed by varying the thickness of ceramic tiles, while maintaining equal areal density of the system. Simulation predictions and trial results is demonstrated both in terms of deformation and damage of the laminates and ...

Preface This thesis was submitted in conformity with the requirements for the degree of Master of Science (MSc) in Civil Engineering. The preparation and evaluation of the experiments were performed at Royal Boskalis Westminster nv. The experiments have been carried out at the Fluid Mechan-I want to thank him for guiding me through the total process of this research. During this graduation work...

Adaptive divergence may be facilitated if morphological and behavioural traits associated with local adaptation share the same genetic basis. It is therefore important to determine whether genes underlying adaptive morphological traits are associated with variation in behaviour in natural populations. Positive selection on low-armour alleles at the Ectodysplasin (Eda) locus in threespine stickl...

In this review paper, an emphasis is made to focus on the history, source, structure, mode of action, and application Nattokinase. The reveals that Nattokinase can act as a potent thrombolytic agent compared other agents which are commercially available. Studies NK have also be proved it useful for dissolving blood clots by converting plasminogen plasmin, further fibrin clots. been isolated fro...
