IntroductionClinical diagnosis of dermatological manifestation of neoplastic skin lesion can pose a diagnostic difficulty at times. Histopathological diagnosis is mandatory for accurate characterization of disease entity for proper and timely management of cases.ObjectiveThe aim of this study was to analyze malignant tumor of skin with respect to age, sex, clinical features and histopathological features and to evaluate the accuracy of clinical diagnosis with histopathological correlation.MethodologyThis is hospital based cross-sectional study conducted at Nepalgunj Medical College and Teaching Hospital, Kohalpur from February 2010 to January 2011. A total of 70 histopathological specimens of skin biopsies were studied and correlated with the clinical diagnosis. The data was entered into Microsoft office excel and analyzed using statistical package for social sciences (SPSS 17.0).ResultsMalignant tumor of skin constituted 21.4% of total cases. In malignant tumor, most common sites were head and neck regions followed by lower limb with keratinocytic tumors being in the majority. Most of the specimens (65.7%) were obtained as excisional biopsies. Seven cases diagnosed as benign lesions clinically, turned out to be malignant on histopathological examination. Out of 13 cases in which clinical diagnosis was of malignancy, only 8 turned out to be malignant, thus for malignant lesions, the clinical diagnosis had a sensitivity of 53.3%, specificity of 90.9% and a positive predictive value of 61.5%.ConclusionsSquamous cell carcinoma was the most common malignant tumor in this study and histopathological correlation significantly modifies the overall management in dermatological disorders where clinical diagnoses are equivocal.Birat Journal of Health SciencesVol.2/No.1/Issue 2/ Jan - April 2017, Page: 156-161

Authors: Pokharel Shailesh Mani , Chaudhary SK , Chaurasiya BD 
Published: November 2017

IntroductionAny disturbance to the normal ouVlow of tears through the nasolacrimal passage causes overﬂow known as epiphora. The clinical symptoms of epiphora range from mild dribble to the continuous ouVlow of tears. Watering of eyes caused by the nasolacrimal drainage obstruction is managed by surgery. One of the many surgeries to treat this is external dacryocystorhinostomy.ObjectiveThe objective of this study was to evaluate the success rate of external dacryocystorhinostomy as well as factors aﬀecting it.MethodologyThis is a retrospective cross-sectional study, conducted in the Department of Ophthalmology, B. P. Koirala Institute of Health Sciences (BPKIHS), Dharan with the approval of Institutional Review Committee, BPKIHS. The medical records of patients who underwent external Dacryocystorhinostomy surgery from April 2011 to April 2016 at BPKIHS were retrospectively reviewed. Statistical analysis was performed using SPSS for windows, version 11.5 (SPSS Inc., Chicago, IL). Binary logistic regression models were used to investigate the association of the surgical outcome with various predicting variables.ResultsThe success rate of the external dacryocystorhinostomy was 78.09%. Factors studied were: age, with a range of 2-81 years; duration of symptoms with a range of 1-84 months; and gender of the patients. The intra-operative factors studied were use of silastic tube, types of ﬂap, and osteotomy size. Among these factors, the duration of symptoms and osteotomy size had signiﬁcant association with the outcome of the surgery p<0.05.ConclusionOur study yielded high success rate in patients with shorter duration of watering of eyes and larger osteotomy size during surgery. Hence, a larger osteotomy size and early intervention is recommended for better surgical outcome. Birat Journal of Health Sciences Vol.2/No.1/Issue 2/ Jan - April 2017, Page: 196-200
Thermal-hydraulic analysis of research reactor core with different LEU fuel types using RELAP5
Authors: El-Sahlamy N. M. 
Published: November 2017

Abstract
In the current work, comparisons between the core performances when using different LEU fuels are done. The fuels tested are UA1X-A1, U3O8-Al, and U3Si2-Al fuels with 19.7 % enrichment. Calculations are done using RELAP5 code to evaluate the thermal-hydraulic performance of the IAEA benchmark 10 MW reactor. First, a reassessment of the slow reactivity insertion transient with UA1X-A1 LEU fuel to compare the results with those reported in the IAEA TECDOC [1]. Then, comparisons between the thermal-hydraulic core performances when using the three LEU fuels are done. The assessment is performed at initial power of 1.0 W. The reactor power is calculated using the RELAP5 point kinetic model. The reactivity feedback, from changes in water density and fuel temperature, is considered for all cases. From the results it is noticed that U3Si2-Al fuel gives the best fuel performance since it has the minimum value of peak fuel temperature and the minimum peak clad surface temperature, as operating parameters. Also, it gives the maximum value of the Critical Heat Flux Ratio and the lowest tendency to flow instability occurrence.
Robust observer based control for axial offset in pressurized-water nuclear reactors based on the multipoint reactor model using Lyapunov approach
Authors: Zaidabadinejad M. , Ansarifar G. R. 
Published: November 2017

Abstract
In nuclear reactor imbalance of axial power distribution induces xenon oscillations. These fluctuations must be maintained bounded within allowable limits. Otherwise, the nuclear power plant could become unstable. Therefore, bounded these oscillations is considered to be a restriction for the load following operation. Also, in order to design the nuclear reactor control systems, poisons concentrations, especially xenon must be accessible. But, physical measurement of these parameters is impossible. In this paper, for the first time, in order to estimate the axial xenon oscillations and ensures these oscillations are kept bounded within allowable limits during load-following operation, a robust observer based nonlinear control based on multipoint kinetics reactor model for pressurized-water nuclear reactors is presented. The reactor core is simulated based on the multi-point nuclear reactor model (neutronic and thermal-hydraulic). Simulation results are presented to demonstrate the effectiveness of the proposed observer based controller for the load-following operation.
The integrity of NSSS and containment during extended station blackout for Kuosheng BWR plant
Authors: Hsu K.-H. , Yuann Y.-R. , Lin A. 
Published: November 2017

Abstract
The Fukushima Daiichi accident occurring on March 11, 2011, reveals that Station Blackout (SBO) may last longer than 8 h. However, the original design may not have sufficient capacity to cope with a SBO for more than 8 h. In view of this, Taiwan Power Company has initiated several enhancements to mitigate the severity of the extended SBO. Based on the improved plant configuration, a SBO coping analysis is performed in this study to assess whether the Kuosheng BWR plant has sufficient capability to cope with SBO for 24 h with respect to maintaining the integrity of the reactor core and containment. The analyses in the Nuclear Steam Supply System (NSSS) and the containment are based on the RETRAN-3D and GOTHIC models, respectively. The flow conditions calculated by RETRAN-3D during the event are retrieved and input to the GOTHIC containment model to determine the containment pressure and temperature response. These boundary conditions include SRV flow rate, SRV flow enthalpy, and total reactor coolant system leakage flow rate.
Experimental investigation of effect of spacer on two phase turbulent mixing rate in subchannels of pressure tube type BWR
Authors: Verma S. K. , Sinha S. L. , Chandraker D. K. 
Published: November 2017

Abstract
Turbulent mixing rate between adjacent subchannels in a two-phase flow has been known to be strongly dependent on the flow pattern. The most important aspect of turbulent motion is that the velocity and pressure at a fixed point do not remain constant with time even in steady state but go through very irregular high frequency fluctuations. These fluctuations influence the diffusion of scalar and vector quantities. The Advanced Heavy Water Reactor (AHWR) is a vertical pressure tube type, heavy water moderated and boiling light water cooled natural circulation based reactor. The fuel bundle of AHWR contains 54 fuel rods set in three concentric rings of 12, 18 and 24 fuel rods. This fuel bundle is divided into number of imaginary interacting flow channel called subchannels. Alteration from single phase to two phase flow situation occurs in reactor rod bundle with raise in power. The two phase flow regimes like bubbly, slug-churn, and annular flow are generally encountered in reactor rod bundle. Prediction of thermal margin of the reactor has necessitated the investigation of turbulent mixing rate of coolant between these subchannels under these flow regimes. Thus, it is fundamental to estimate the effect of spacer grids on turbulent mixing between subchannels of AHWR rod bundle.
Modelling the Antarctic and Northern Hemisphere ice-sheet changes with global
climate through the Glacial cycle
Authors: Budd W. F. , Coutts B. , Warner Roland C. 
Published: November 2017

The future behaviour of the Antarctic ice sheet depends to some extent on its
current state of balance and its past history. The past history is primarily
influenced by global climate changes, with some small amount of local feedback,
and by sea-level changes generated primarily by the Northern Hemisphere ice-sheet
changes, again with a small amount of feedback from the Antarctic ice sheet. An
ice-sheet model which includes ice shelves has been used to model the Antarctic
region and the whole Northern Hemisphere high-latitude region through the last
ice-age cycle. For the climate forcing, the results from the global energy-balance
model of Budd and Rayner (1990) are used. These are based on the Earth's orbital
radiation changes with ice-sheet albedo feedback. Additional sensitivity studies
are carried out for the amplitudes of the derived temperature changes and for
changes in precipitation over the ice-sheets. For the Antarctic snow-accumulation
changes, the results from the Voslok ice core are used with proportional changes
over the rest of the ice sheet. For the sea-level variations, the results
generated by the Northern Hemisphere ice-sheet changes provide the primary
forcing, but account is also taken of the feedback effects from bed response under
changing ice and ocean loading and from the Antarctic changes.
The results of the modelling provide a wide range of features for comparison
with observations, such as the margins of maximum ice extent. For the Northern
Hemisphere the results indicate that the peak mean temperature shift required for
the ice-edge region is about -12°C, whereas outside the ice-sheet region this
change is smaller but over the ice sheets it is larger. For the Antarctic region
during the ice age the interior region decreases in thickness, due to lower
accumulation, while the grounding-edge region expands and thickens due to the
sea-level lowering. As a result, the derived present state of balance shows a
positive region over most of inland East Antarctica, whereas coastal regions tend
to be nearer to balance, with some slightly negative regions around some of the
large ice shelves and coastal ice streams which are still adjusting slowly to the
post-ice-age changes of sea level and accumulation rates.
Simulations of the Northern Hemisphere through the last Glacial-interglacial
cycle with a vertically integrated and a three-dimensional thermomechanical
ice-sheet model coupled to a climate model
Authors: Calov R. , Marsiat I. 
Published: November 2017

We present simulations of the Northern Hemisphere land ice through the last
glacial-interglacial cycle with a vertically integrated ice-sheet model and a
three-dimensional thermomechanical ice-sheet model. Both models are coupled
asynchronously to the zonally averaged Louvain-la-Neuve climate model, which
includes simplified treatments of the atmosphere, ocean and sea ice. The
two-dimensional vertically integrated ice-sheet model, which contains no
thermomechanical coupling, was developed in spherical coordinates (Marsiat, 1994).
The three-dimensional thermomechanical ice-sheet model was developed using the
two-dimensional vertically integrated model as source.
We compare results of the vertically integrated with those of the
thermomechanical ice-sheet model. in the thermomechanical model the deformation
properties of ice depend on the temperature within the ice and the enhancement
factor; the latter is introduced to model, in a simplified approach, the different
flow properties of Pleistocene and Holocene ice due to varying dust content. The
computations with the thermomechanical model show that the growth and decay of the
Northern Hemisphere ice sheets can be modelled with a common enhancement factor
for all ice sheets. It is shown that there are model set-ups for the
thermomechanical model yielding temporal developments of the total ice volume
comparable to those of the vertically integrated model. Furthermore, we
demonstrate that for the coupled climate/cryosphere system the total ice volume
depends considerably on the enhancement factor.
Simulation of the influence of ice rheology on velocity profiles and ice-sheet
mass balance
Authors: Wang W. L. , Warner Roland C. 
Published: November 2017

Assessment of the effect of the Antarctic ice sheet on sea level requires an
accurate determination of its current state of balance. This is usually done by
comparing the ice net accumulation for an area with the net outward flow of the
ice. To obtain the net outward flux to better than 20% accuracy the relationship
between the column-integrated ice flux and measurements of ice-sheet thickness and
surface velocity must be considered. That relationship is summarised by the ratio
of depth-averaged velocity
ϒ
to surface velocity γs
in areas where ice sliding can be neglected, this ratio strongly
reflects the rheological properties of the ice and depends on the shear
strain-rate profile through the ice column, which is influenced by profiles of
stress, temperature and ice-crystal fabric.
We present calculations from a flowline
model of a hypothetical large ice sheet to demonstrate how development of an
anisotropic ice-crystal fabric can influence the depth profile of horizontal
velocity. The temperature dependence of ice rheology, combined with typical
ice-sheet temperature profiles, yields a more block-like velocity profile with
increasing to
values in the range 0.89-0.96 from the isothermal rheology value of 0.8. Our
results show that the onset of enhanced shear flow with increasing shear strain,
as a consequence of anisotropy, and then a reduction of enhancement nearer the
bedrock, can modify the velocity profile, giving values typically
in the range 0.86-0.91. Smaller values than these may also occur for rougher
bedrock or thinner ice.
Simulation of the Antarctic ice sheet with a three-dimensional polythermal
ice-sheet model, in support of the EPICA project

Published: November 2017

The three-dimensional polythermal ice-sheet model SICOPOLIS is applied to the
entire Antarctic ice sheet in support of the European Project for Ice Coring in
Antartica (EPICA). in this study, we focus on the deep ice core to be drilled in
Dronning Maud Land (Atlantic sector of East Antarctica) as part of EPICA. It has
not yel been decided where the exact drill-site will be situated. Our objective is
to support EPICA during its planning phase as well as during the actual drilling
process.
We discuss a transient simulation with a climate forcing derived from the
Vostok ice core and the SPECMAP sea-level record. This simulation shows the range
of accumulation, basal temperature, age and shear deformation to be expected in
the region of Dronning Maud Land. Based on these results, a possible coring
position is proposed, and the distribution of temperature, age, horizontal
velocity and shear deformation is shown for this column.
Detailed topography of Roosevelt Island and Siple Dome, West
Antarctica
Authors: Scambos Ted A. , Nereson Nadine A. , Fahnestock Mark A. 
Published: November 2017

Detailed surface topography is presented for two dome features of the West
Antarctic ice sheet, Siple Dome and Roosevelt Island. Both these domes show linear
topographic features, or “scars”, on [heir flanks. Topography is determined from a
combination of existing digital elevation models (DEMs; based on satellite radar
altimctry), photoclinomctry (using advanced very high-resolution radiometer images
to quantitatively infer topographic details) and, in the case of Siple Dome,
surface global positioning system topographic profiles. The enhanced DEMs provide
heights and shapes for a variety of surface features in the vicinity of the domes,
such as scars, surface undulations, ice rises and the domes themselves.
The DEMs indicate that the scar features on both domes are high relative to
adjacent rapid-ice-llow areas. Scars and other related morphologic features on the
flanks of both domes can be interpreted as former active ice streams and stream
margins. For Siple Dome, this interpretation is confirmed by radar profiling. The
evolution of the topographic height of the scars is a combination of two
processes: initial elevation rise due to a positive mass balance at the shear
margin in the immediate aftermath of shut-down of the ice stream; and later
downslope flow as the scars become part of the dome and the dome surface velocity
field. Superimposed on these events is accumulation, which buries the original
shear margin but elevates the scar surface expression. Depending upon the timing
of shut-flown, and the relative magnitude of these processes, the height of the
scars above the current rapidly flowing surfaces may be indicative of ice-sheet
thinning since shut-down, or dome expansion across former ice-stream trunks in a
more or less steady-state ice sheet.
