Abstract:
The vertical directional solidification (VDS) process was developed to grow the Sb-based extremely high order
quality crystals underground condition since 1993. The experimental results of detached growths are reviewed
with focus on the growth of Sb-based semiconductors. The entire detached crystal by VDS-process in vacuum
sealed ampoule by the prerequisite conditions of the crystallization by slow freezing of melt near crystal-melt
interface is accomplished. The necessary conditions for crystalline solidification, the influence of different
convections on high order crystal quality is investigated. The entire detached growths experimental data is
analyzed. Based on investigation and analysis of the entire detached growth results by VDS-process, "the
detached phenomenon and fundamental science" is reported..

Abstract:
Risks related to the construction sector result from instabilities in the external environment that, associated with
the complexities of internal processes, affect the compliance with project schedules. Although risk management
is part of project management, few companies apply it, especially small ones. This article aims to identify and
rank the main risk factors that affect the project schedules of small national construction companies. Based on
the literature, 43 risk factors associated with the construction environment were identified, but only 26 were
directly related to project delays. A survey was conducted on a non-probabilistic sampling, characterized by 133
professionals and specialists working in small construction companies.......

Abstract:
In Brazil, the accounting of transportation costs and the movement of oil and its derivatives is carried out
between Petrobras and its subsidiaries under two contract forms: tariffs and operation-maintenance. In the tariff
agreement, the subsidiary uses its facilities and operation-maintenance, it is responsible for the operationmaintenance
of the contractor's facilities. The costs of these operations are accounted for apportioned and
allocated to only two cost centers: oil and oil products. This paper aims to present a methodology for an
accounting of logistics costs that contemplate the operations in each unit, identifying the efficiency of each
process. Through the analysis of data in the budget and logistics areas, it was verified the possibility of
accounting by specific cost centers, defined for each type of product moved (oil or derivatives) in each terminal,
involved in tariff contracts, besides to change the measurement of fare contracts, prepare the cost center
structure, adjust the allocation cycles to the new method, and update the internal order master data according to
their new structures. As a result, the managers of each production unit are expected to contribute by providing a
clearer and more objective view of costs.

Abstract:
Flood is a serious physical phenomenon which is now a day becomes a common scenario around the world.
The flood management planning is essential for decreasing the damages that occurred due to flood like
situations. There are several flood management techniques and methods but the problem still persists. Hence in
order to have better understanding about floods and flood management strategies, a survey was conducted in
three parts. First part of survey is for an Expert people and other parts of surveys are for PG and UG students of
Civil engineering department respectively. The main objective of the paper is to determine the Expert people's
opinion, their perception and understanding about flood phenomena. And based on their experience, identify the
critical parameters involved in causing flood and steps involved in flood management. The feedbacks from the
surveys are then analyzed thoroughly which shows that the green canopy covers should be increased;
deforestation and urbanization should be controlled to some extent to manage floods effectively..

Abstract:
The purpose of this research was to find the most suitable material for manufacturing camshaft
for modified design. There are various factors that lead to a camshaft failure like material properties, vibration,
contact fatigue etc. In this research structural analysis of camshaft was done in ANSYS for three different
materials and results for both standard camshaft model and modified camshaft model was obtained and
compared. ANSYS results for total deformation, maximum stress, maximum strain and factor of safety are
considered..
