Ensuring mycoplasma-free cell culture is of prime importance as they severely affect cellular characteristics leading to experimental artefacts and spurious results. Various methods persist for mycoplasma detection; out of the whole array of methods polymerase chain reaction (PCR) is the most favoured one because it is highly sensitive, specific and quick. The PCR-based detection procedure invo...

Practical Conscious Sedation offers the ability to provide effective and safe dental treatment under different types of conscious sedation techniques. Sometimes, it is impossible to provide dental treatment for patients with a real fear of dentistry or patients with medically compromised conditions. Control of anxiety and pain is fundamental to the practice of dentistry. Basic sedation techniqu...

In this papera switching control strategy for robust stabilization of the 2nd-order non-holonornic 2-DOF SCARA robot Ft21)l is presented. The Ist joint is actuated by a direct drive motor, whereas the 2nd joint is equipped with a brake. The unactuated 2nd joint is controlled by non-collocated linearization and a PDcontroller. A stability region is den”ued and robustness is achieved by exploitin...

Human observers are able to localize the relative position of objects defined by Gaussian variations in either luminance (1st order) or contrast (2nd order). However, positional sensitivity is significantly poorer for 2nd- than for 1st-order stimuli. These judgments require the visual system to construct a representation of pertinent variation from a number of individual retinal samples-a proce...

STIMULI. The 1st-order stimuli are moving sine gratings. The 2nd-order stimuli are fields of static visual texture, whose contrasts are modulated by moving sine gratings. Neither the spatial slant (orientation) nor the direction of motion of these 2nd-order (microbalanced) stimuli can be detected by a Fourier analysis; they are invisible to Reichardt and motion-energy detectors. METHOD. For the...

OBJECTIVE To evaluate occurrence of synchronous and metachronous malignant tumours, to find tumour types, age group, and relationship to treatment received. METHODS Previously diagnosed 1st primary tumour cases experiencing a synchronous or metachronous tumour, seen at AOI from February 2003 to August 2009 (78 months) were included. The cases were analyzed for morphology/histology of 1st prim...

The above two books by dental scientists have been received by this editor for review. The first is intended for use by dentists and dental students, as was the first edition. Many dental researchers have contributed to this updated survey of dental uses of fluoride. What is remarkable about Fluoride in Dentistry (2nd Edition), especially to anyone concerned with a more interdisciplinary approa...
