Granite fines which are the by-product produced in granite factories while cutting huge granite rocks to the desired shapes, while cutting the granite rocks, the powder produced is carried by the water and this water is stored in tanks. After drained of water the granite dust remained is disposed on the lands. Disposing this granite fines is a major problem due its fineness. Hence an effect is made to utilize this fine granite powder in as a filler material in concrete. For that the basic properties of granite fines such as size, fineness, specific gravity, and moisture content were tested. The result shows that the property of granite fines is similar to that of ordinary sand. Therefore, granite fines can be effectively used as a replacement material for fine aggregate in concrete. For investigation purpose cubes are casted with 7 different proportions of granite fines and fine aggregate. The replacement percentage of granite fines to fine aggregate are 0, 10, 20, 30, 40, 50 and 100 for M20 mix proportions, specimens are tested after 28 days of curing, for compression strength, flexural and split tensile strength. The specimen casted with 40 % replacement of granite fines to fine aggregate gives higher strength when compared to control specimen.

Platelets are known to release several
growth factors which stimulate tissue
regeneration. Several techniques for platelet
concentrates have been introduced in surgical
field for the prevention of hemorrhage and
acceleration of tissue regeneration. Platelet rich
plasma (PRP) and plasma rich in growth factors
(PRGF) belong to the first generation of platelet
concentrates. PRP and PRGF require chemical
additives such as anticoagulants and thrombin
or calcium chloride to induce fibrin polymerization
before applying to the surgical site. Platelet
rich fibrin (PRF) and concentrated growth factors
(CGF), as second generation of platelet concentrate,
utilizes patient’s venous blood alone to
trigger platelet activation and fibrin polymerization.
PRF and CGF can be used as alternative
to traditional barrier membrane over bone graft,
therefore acceleration of tissue regeneration is
acquired. Unlike PRF using constant centrifugation
speed, CGF utilizes altered centrifugation
speed to produce much larger, denser and richer
fibrin matrix containing growth factors. A new concept
of fabricating growth factors-enriched bone
graft matrix (also known as “sticky bone”) using
autologous fibrin glue has been demonstrated
since 2010. Sticky bone provides stabilization
of bone graft in the defect, and therefore, accelerates
tissue healing and minimizes bone loss
during healing period. This report presents the
method of preparing and utilizing CGF and sticky
bone, and clinical cases that support its use.

ABSTRACT: We describe the CoJACK cognitive architecture. It is designed to provide an intuitive, high level behaviour representation language that exhibits variability across individuals and across time for use in synthetic environments. The included moderator layer enables modelling of physiological factors and affect. We report initial results of an investigation of variability and time-based moderation in the dTank simulation. The results show that moderation leads to interesting effects and that variability is generated in a principled and repeatable fashion. 1.

Current methods for building models using implicit volume techniques present problems defining accurate and controllable blend shapes between implicit primitives. We present new methods to extend the freedom and control- lability of implicit volume modeling. The main idea is to use a free-form curve to define the profile of the blend region between implicit primitives. The use of a free-form
