some specific features: very long transcription units, deregulated termination, and transcription of non-coding satellite repeats. Here, based on the modern view on a role of RNA interference machinery in regulation of genome expression,... more
AbstractAutomated debugging is becoming increasingly important as the size and complexity of software increases. This paper makes a case for using constraint-based data structure repair, a recently developed technique for fault recovery,... more
Direct Metal Laser Re-Melting is a variant of the Selective Laser Sintering process, a Rapid Prototyping (RP) technology. This tool-less manufacturing technology has the potential of producing complex, high quality components from... more
Novel, solid catalysts of µ 3-oxo-bridged Co/Mn cluster complexes, viz., [Co 3 (O)(CH 3 COO) 6 (pyridine) 3 ] + , [Mn 3 (O) (CH 3 COO) 6 (pyridine) 3 ] + , and CoMn 2 (O)(CH 3 COO) 6 (pyridine) 3 (denoted Co 3 (O), Mn 3 (O), and CoMn 2... more
Purpose: Recently the emphasis has been laid upon the carbohydrate mediated liposomal interactions with the target cells. Among the various carbohydrate ligands, such as glycoproteins, glycolipids, viral proteins, polysaccharides,... more
As well as acting as a moderator and reflector, graphite is used as a structural component in many gas-cooled fission nuclear reactors. Therefore the ability to predict the structural integrity of the many graphite components which make... more
The recent advancement in high performance semiconductor packages has been driven by the need for higher pin count and superior heat dissipation. A one-piece cavity lid flip chip BGA package with high pin count and targeted reliability... more
Transportation authorities have to support high costs for track maintenance due to the wear of the rails and to crack generation at some particular points along the line. To set up the planning of the maintenance and inspection... more
The paper addresses the damage tolerance of sandwich structures, where the prevention and limitation of delamination failure are highly important design issues. Due to the layered composition of sandwich structures, face-core interface... more
This article discusses the problem of graphitization that can occur in carbon steels exposed to high temperature for extended time when these are present in pressure vessels and piping. Several case studies are described dealing with... more
Silicon carbide sustains chemical and mechanical deterioration during tribological exposure under water lubrication. In particular, tribochemical wear leads to the formation of a thin (tens to hundreds of nanometre) layer composed of... more
The adequate fire protection of storage vessels to guard against their catastrophic failure is recognised to be of key importance. The radiant energy flux from large open hydrocarbon fires can be sufficiently high to threaten the... more
This paper investigates the combined effect of corrosion and fatigue on the growth of cracks that arise from natural corrosion in steel bridges. It is shown that if these two effects need to be simultaneously analyzed. If not, then the... more
Cleaning methods employed in last oil spills usually require direct contact or the intervention of external agents that can lead to additional contamination and damage of treated surfaces. As an alternative, a laser-based methodology is... more
Selective laser sintering (SLS) Rapid prototyping Finite element Polycarbonate Process modelling a b s t r a c t A transient three-dimensional finite element model is developed to simulate the phase transformation during the selective... more
The paper gives the description of up-to-date metho d for concrete testing based on the drypoint contact ultrasonic transducers technology, ad vanced methods of computer tomography and new techniques of signal processing using SAFT... more
Unpaved roads are often considered to be the predominant sediment source in forested catchments. In steep, wet climates roads can cause a 10-to 300-fold increase in the landslide erosion rate, and this increase is due to the effects of... more
Significant amounts of residual stresses are often generated during welding and result in critical degradation of the structural integrity and performance of components. Neutron diffraction has become a well established technique for the... more

Stiffened composite constructions are increasingly being used in the primary structures of aircraft. One key component in these structures is the assembly between the skin and the stringer. The purpose of the stringers sandwiched between... more
Purpose To evaluate the visual and structural outcomes of scleral patch grafting in cases of scleral defect. Methods The study was a retrospective interventional case series. Medical records of all patients who underwent scleral patch... more
Background and purpose: A recent confirmatory factor analysis (CFA) of the Test of Performance Strategies (TOPS) by Lane, Harwood, Terry, and Karageorghis [2004. Confirmatory factor analysis of the Test of Performance Strategies (TOPS)... more
Steel structures corrode when exposed to the environment, and their capacity is reduced accordingly. In practice, when a member is found corroded during inspection, it is necessary to estimate the residual capacity of corroded members in... more
Given its active and enquiry-driven character, fieldwork is seen as an important way to develop geographical understanding of the world, during which cognitive and affective learning reinforce each other. The present study aims to give... more
Because lignin limits the use of wood for fiber, chemical, and energy production, strategies for its downregulation are of considerable interest. We have produced transgenic aspen ( Populus tremuloides Michx.) trees in which expression of... more
Background The term ''bulbous nose'' is used to describe a large or boxy nasal tip. Typically, correction of the bulbous tip has been achieved through a variety of cartilagemodifying maneuvers based on incision or excision of the lower... more
In our search for new violet-excitable dyes with improved photophysical and photochemical properties, we examined several halogen-substituted hydroxycoumarins and found that chlorinated derivatives are at least as bright as their... more
