Study of mud banks of the Kerala coast a retrospect
The mud banks, an unique feature of the Kerala coast during
the southwest monsoon where the surf ridden nearshore waters
over restricted areas become highly adjacent due to certain physicochemical
factors have been under investigation for more than a century.
These areas play an important role in the socio-economics of
the coastal fisher folk during the poverty stricken southwest monsoon
period. Considering the importance of mud banks from the fishing
point of view, the Central Marine Fisheries Research Institute.
Cochin has been monitoring the phenomenon and carried out a multidisciplinary
exclusive study during 1971-72, on the various physicochemical
aspects in respect of origin, maintenance, shifting, dissipation,
ecology and fisheries of the mud banks, especially that of
Alleppey area. The study brought to light a good amount of new
information on this curious phenomenon. The present article is a
review of the studies conducted by the CMFRl
Design of a low-noise aeroacoustic wind tunnel facility at Brunel University
This paper represents the design principle of a quiet, low turbulence and moderately high speed aeroacoustic wind tunnel which was recently commissioned at Brunel University. A new hemi-anechoic chamber was purposely built to facilitate aeroacoustic measurements. The wind tunnel can achieve a maximum speed of about 80 ms-1. The turbulence intensity of the free jet in the potential core is between 0.1–0.2%. The noise characteristic of the aeroacoustic wind tunnel was validated by three case studies. All of which can demonstrate a very low background noise produced by the bare jet in comparison to the noise radiated from the cylinder rod/flat plate/airfoil in the air stream.The constructions of the aeroacoustic wind tunnel and the hemi-anechoic chamber are financially supported by the School of Engineering and Design at Brunel University
Critical success factors for instrumentation and control projects within the power industry in South Africa
Abstract: Instrumentation and control projects entail an upgrade or refurbishment of a portion of the current process control system. The changes introduced present integration challenges to people, the plant and operating guidelines and procedures. The successful implementation of these time sensitive projects depends on factors such as change management effectiveness, stakeholder investment and competency of the project team. Project success factors identified across the lifecycle of the project enables the organization to filter down on challenges and risks contained within each project phase. The research identifies critical success factors specific to instrumentation and control projects within the South African power industry. The framework is developed through the descriptive analysis of feedback received from key stakeholders within the organization
Alternate cyclin D1 mRNA splicing modulates P27\u3csup\u3eKlP1\u3c/sup\u3e binding and cell migration
Cyclin D1 is an important cell cycle regulator but in cancer its overexpression also increases cellular migration mediated by p27KlP1 stabilization and RhoA inhibition. Recently, a common polymorphism at the exon 4-intron 4 boundary of the human cyclin D1 gene within a splice donor region was associated with an altered risk of developing cancer. Altered RNA splicing caused by this polymorphism gives rise to a variant cyclin D1 isoform termed cyclin D1b, which has the same N-terminus as the canonical cyclin D1a isoform but a distinct C-terminus. In this study we show that these different isoforms have unique properties with regard to the cellular migration function of cyclin D1. Whereas they displayed little difference in transcriptional co-repression assays on idealized reporter genes, microarray cDNA expression analysis revealed differential regulation of genes including those that influence cellular migration. Additionally, while cyclin D1a stabilized p27KIP1 and inhibited RhoA-induced ROCK kinase activity, promoting cellular migration, cyclin D1b failed to stabilize p27KIP1 or inhibit ROCK kinase activity and had no effect on migration. Our findings argue that alternate splicing is an important determinant of the function of cyclin D1 in cellular migration
Indian nurses in the United Kingdom: a two-phase study of the expatriate-host country national relationship
It is well established that expatriates need support from host country nationals (HCNs) to successfully adjust in their new location, and subsequently perform well on their jobs. Drawing on a sample of 149 Indian nurses in the United Kingdom, this two-phase study illustrates how expatriate-HCN interactions unfold over time (two years). To do this, we draw upon social identity theory and show that effective expatriate-HCN relationship building (i.e., perceived categorization and perceived values similarity) lead to HCN support and, subsequently, expatriate adjustment.
Results confirmed that perceptions of categorization and value similarity significantly impacted HCN willingness to offer support. We also find that expatriate age, education level, and time spent in the host country significantly impact adjustment. We discuss theoretical and practical implications and offer suggestions for future research
Raman scattering mediated by neighboring molecules
Raman scattering is most commonly associated with a change in vibrational state within individual molecules, the corresponding frequency shift in the scattered light affording a key way of identifying material structures. In theories where both matter and light are treated quantum mechanically, the fundamental scattering process is represented as the concurrent annihilation of a photon from one radiation mode and creation of another in a different mode. Developing this quantum electrodynamical formulation, the focus of the present work is on the spectroscopic consequences of electrodynamic coupling between neighboring molecules or other kinds of optical center. To encompass these nanoscale interactions, through which the molecular states evolve under the dual influence of the input light and local fields, this work identifies and determines two major mechanisms for each of which different selection rules apply. The constituent optical centers are considered to be chemically different and held in a fixed orientation with respect to each other, either as two components of a larger molecule or a molecular assembly that can undergo free rotation in a fluid medium or as parts of a larger, solid material. The two centers are considered to be separated beyond wavefunction overlap but close enough together to fall within an optical near-field limit, which leads to high inverse power dependences on their local separation. In this investigation, individual centers undergo a Stokes transition, whilst each neighbor of a different species remains in its original electronic and vibrational state. Analogous principles are applicable for the anti-Stokes case. The analysis concludes by considering the experimental consequences of applying this spectroscopic interpretation to fluid media; explicitly, the selection rules and the impact of pressure on the radiant intensity of this process
Origin of anomalous breakdown of Bloch's rule in the Mott-Hubbard insulator MnTe
We reinvestigate the pressure dependence of the crystal structure and
antiferromagnetic phase transition in MnTe by the rigorous and reliable
tool of high pressure neutron powder diffraction. First-principles density
functional theory calculations are carried out in order to gain microscopic
insight. The measured N\'eel temperature of MnTe is found to show unusually
large pressure dependence of K GPa. This gives rise to large
violation of Bloch's rule given by , to a value of -6.0 0.1 for
MnTe. The ab-initio calculation of the electronic structure and the
magnetic exchange interactions in MnTe, for the measured crystal structures
at different pressures, gives the pressure dependence of the Ne\'el
temperature, to be -5.61, in close agreement with experimental
finding. The microscopic origin of this behavior turns to be dictated by the
distance dependence of the cation-anion hopping interaction strength
Acute military psychiatric casualties from the war in Iraq
Background: The view that most military personnel evacuated from war zones are suffering from combat stress reactions, or are otherwise traumatised by the horrors of war, has an impact on all aspects of military psychiatry.
Aims: To delineate the reasons for psychiatric aeromedical evacuation from Iraq from the start of build-up of UK forces in January 2003 until the end of October that year, 6 months after the end of formal hostilities.
Method: A retrospective study was conducted of field and in-patient psychiatric assessments of 116 military personnel evacuated to the UK military psychiatric in-patient facility in Catterick Garrison.
Results: Evacuees were mainly non-combatants (69%). A significant proportion were in reserve service (21%) and had a history of contact with mental health services (37%). Only 3% had a combat stress reaction. In over 85% of cases evacuation was for low mood attributed to separation from friends or family, or difficulties adjusting to the environment.
Conclusions: These findings have implications especially for screening for suitability for deployment, and for understanding any longer-term mental health problems arising in veterans from Iraq
