Adults changing careers through university education: Making meaning of quantitative career assessment scores through an integrative structured interview
Authors: McMahon Mary , Watson Mark , Zietsman Louis 
Published: May 2018

Orientation: Career change in adulthood is becoming a norm and university education is a pathway to new careers. Career psychologists are well positioned to assist adult career changers. Contemporary approaches to diverse client groups and integrating career assessment with narrative career counselling are needed. Research purpose: This article reports on an innovative approach to assisting adult career changers through the complementarity of an integrative structured interview (ISI) and the self-directed search (SDS) career assessment questionnaire. Motivation for the study: The overall aim of this research was to explore the career transition experiences of adult university learners. The secondary aims were to investigate the complementarity of quantitative career assessment (i.e. the SDS) and narrative interviewing (i.e. the ISI) and how adult university learners engaged with the ISI. This article reports on the secondary aims by considering excerpts from case study interviews. Research design, approach and method: This qualitative, exploratory, descriptive, multiple case study research presents case studies of two adult university learners: an Australian male student and a South African female student. Participants completed the SDS prior to engaging in a four-part semi-structured interview that incorporated the ISI. Main findings: The findings revealed that the participants told rich stories that related past, present and future life and work experiences to their SDS three-letter codes. Their stories revealed how quantitative career assessment scores and narrative career counselling may be integrated through a structured interview. Practical and managerial implications: Adult career changers told meaningful stories about their quantitative SDS scores. The findings suggest that narrative career counselling may be useful for adult career changers and that the ISI could provide a model for career psychologists who support them. Implications of the findings suggest that managers and human resource personnel working in organisations may assist adult career changers by offering them access to psychological support that uses quantitative career assessment as a foundation for career story telling. Contribution or value-add: The research provides an innovative response to challenges in career psychology to develop contemporary responses to diverse client groups and to integrate career assessment with narrative career counselling.

ABSTRACT
Background: Many flaps have been described for reconstruction of lower extremity defects, including, Latissimus Dorsi, Rectus abdominis, Anterolateral thigh perforator flaps, each having advantages and disadvantages. The defect location, size and specific geometric pattern of defect influences the type of flap that can be used. In this case series, we describe the specific situations where the use of chimeric latissimus dorsi–serratus anterior (LD + SA) free flaps are of advantage in providing complete wound cover. Materials and Methods: Case records of all patients who underwent LD + SA free flap transfer for lower extremity trauma at Amandeep Hospital, from Feb 2006 to Feb 2017 were reviewed. Patients were categorised based on the anatomical location and size of defect. The method of usage of the chimeric segments, recipient vessels and type of anastomosis were noted. Flap complications, if any were reviewed. Result: 47 patients with lower limb defects were included in the study. All cases were post traumatic in nature. Defect size ranged from 180 sq cm to 1050 sq cm. Average defect size was 487.70 sq cm. All patients underwent soft tissue reconstruction with LD + SA flap. Complete wound cover was obtained. Conclusion: Latissimus dorsi + Serratus anterior free tissue transfer is an effective, reliable method of providing cover to extensive lower limb traumatic defects with minimal donor site morbidity, with added freedom of inset and flap positioning. Specific use is seen in patients with broad proximal defect, long defect in the leg, defects involving adjacent anatomical areas and in large defect with dead space.

ABSTRACTAlthough both pulmonary and extrapulmonary tuberculosis (TB) are commonly encountered in developing countries, tenosynovitis is an uncommon presentation of musculoskeletal TB. TB mimics a lot of other conditions and causes diagnostic dilemma in day-to-day practice. We present the case of a 30-year-old male who presented with the complaints of swelling of right index finger which was initially suspected to be giant cell tumour of the flexor tendon sheath but on histological examination turned out to be tuberculous tenosynovitis.

Published: May 2018

ABSTRACT
Background: The finger skin and soft-tissue defects are reconstructive challenges due to their nature and the intricate extensor apparatus and flexors it protects. The reverse dorsal metacarpal artery (RDMA) is a time-tested option for the reconstruction of the same. Materials and Methods: A total of 14 cases of RDMA flap for finger defects involving proximal to distal phalanx were performed. Thirteen of these patients were male and one patient female and the most common mode of injury was occupational in nature followed by road traffic accident. The overall appearance was assessed for the flap and the donor site. The associated injuries and the range of motion were noted. Results: All but one flap survived completely. One patient had partial distal flap loss, which was tackled with split-thickness skin grafting. The flap size varied from 3.5 cm × 1.5 cm to 9 cm × 2 cm with mean of 6.64 cm × 1.72 cm. The mean age of the patients was 33.4 years. All the patients had acceptable aesthesis. The donor site had no complications and healed with linear scar. Conclusions: RDMA flap is a reliable flap for finger defects reconstruction. The range of movement mainly depends on the associated injury rather than flap transfer alone and to prove this we require doing analysis of range of movement in patients with flap done alone or with associated injuries.
Snowfall retrieval at X, Ka and W bands: consistency of backscattering and microphysical properties using BAECC ground-based measurements

Published: May 2018

Abstract. Radar-based snowfall intensity retrieval is investigated at
centimeter and millimeter wavelengths using co-located
ground-based multi-frequency radar and video-disdrometer observations. Using data from four snowfall events, recorded
during the Biogenic Aerosols Effects on Clouds and Climate (BAECC) campaign in Finland, measurements of
liquid-water-equivalent snowfall rate S are correlated to radar equivalent reflectivity factors Ze,
measured by the Atmospheric Radiation Measurement (ARM) cloud radars operating at X, Ka and W frequency bands. From these
combined observations, power-law Ze–S relationships are derived for all three frequencies considering
the influence of riming. Using microwave radiometer observations of liquid water path, the measured precipitation is
divided into lightly, moderately and
heavily rimed snow. Interestingly lightly rimed snow events show a spectrally distinct
signature of Ze–S with respect to moderately or heavily rimed snow cases. In order to understand the
connection between snowflake microphysical and multi-frequency backscattering properties, numerical simulations are
performed by using the particle size distribution provided by the in situ video disdrometer and retrieved ice particle
masses. The latter are carried out by using both the T-matrix method (TMM) applied to soft-spheroid particle models
with different aspect ratios and exploiting a pre-computed discrete dipole approximation (DDA) database for rimed
aggregates. Based on the presented results, it is concluded that the soft-spheroid approximation can be adopted to
explain the observed multi-frequency Ze–S relations if a proper spheroid aspect ratio is selected. The
latter may depend on the degree of riming in snowfall. A further analysis of the backscattering simulations reveals that
TMM cross sections are higher than the DDA ones for small ice particles, but lower for larger particles. The differences of computed cross sections for larger and smaller particles are compensating for each other. This may explain why the soft-spheroid approximation is satisfactory for radar reflectivity simulations under study.

Published: May 2018

Abstract. The combined effects of elevated pCO2 and temperature were investigated
during an experimentally induced autumn phytoplankton bloom in vitro sampled from
the western English Channel (WEC). A full factorial 36-day microcosm
experiment was conducted under year 2100 predicted temperature (+4.5 ∘C)
and pCO2 levels (800 µatm). Over the
experimental period total phytoplankton biomass was significantly influenced
by elevated pCO2. At the end of the experiment, biomass increased
6.5-fold under elevated pCO2 and 4.6-fold under elevated temperature
relative to the ambient control. By contrast, the combined influence of
elevated pCO2 and temperature had little effect on biomass relative to
the control. Throughout the experiment in all treatments and in the control,
the phytoplankton community structure shifted from dinoflagellates to
nanophytoplankton . At the end of the experiment, under elevated pCO2
nanophytoplankton contributed 90 % of community biomass and was dominated
by Phaeocystis spp. Under elevated temperature, nanophytoplankton comprised 85 % of
the community biomass and was dominated by smaller nanoflagellates. In the
control, larger nanoflagellates dominated whilst the smallest
nanophytoplankton contribution was observed under combined elevated
pCO2 and temperature (∼ 40 %). Under elevated
pCO2, temperature and in the control there was a significant decrease
in dinoflagellate biomass. Under the combined effects of elevated pCO2
and temperature, dinoflagellate biomass increased and was dominated by the
harmful algal bloom (HAB) species, Prorocentrum cordatum. At the end of the experiment,
chlorophyll a (Chl a) normalised maximum photosynthetic rates (PmB) increased
> 6-fold under elevated pCO2 and > 3-fold under
elevated temperature while no effect on PmB was observed when
pCO2 and temperature were elevated simultaneously. The results suggest
that future increases in temperature and pCO2 simultaneously do not
appear to influence coastal phytoplankton productivity but significantly
influence community composition during autumn in the WEC.
Integrated assessment of future potential global change scenarios and their hydrological impacts in coastal aquifers – a new tool to analyse management alternatives in the Plana Oropesa-Torreblanca aquifer

Published: May 2018

Abstract. Any change in the components of the water balance in a coastal
aquifer, whether natural or anthropogenic, can alter the freshwater–salt
water equilibrium. In this sense climate change (CC) and land use and land
cover (LULC) change might significantly influence the availability of
groundwater resources in the future. These coastal systems demand an
integrated analysis of quantity and quality issues to obtain an appropriate
assessment of hydrological impacts using density-dependent flow solutions.
The aim of this work is to perform an integrated analysis of future potential
global change (GC) scenarios and their hydrological impacts in a coastal
aquifer, the Plana Oropesa-Torreblanca aquifer. It is a Mediterranean aquifer
that extends over 75 km2 in which important historical LULC changes
have been produced and are planned for the future. Future CC scenarios will
be defined by using an equi-feasible and non-feasible ensemble of projections
based on the results of a multi-criteria analysis of the series generated
from several regional climatic models with different downscaling approaches.
The hydrological impacts of these CC scenarios combined with future LULC
scenarios will be assessed with a chain of models defined by a sequential
coupling of rainfall-recharge models, crop irrigation requirements and
irrigation return models (for the aquifer and its neighbours that feed it),
and a density-dependent aquifer approach. This chain of models, calibrated
using the available historical data, allow testing of the conceptual
approximation of the aquifer behaviour. They are also fed with series representatives of potential global
change scenarios in order to perform a sensitivity analysis regarding future
scenarios of rainfall recharge, lateral flows coming from the hydraulically
connected neighbouring aquifer, agricultural recharge (taking into account
expected future LULC changes) and sea level rise (SLR). The proposed analysis
is valuable for improving our knowledge about the aquifer, and so comprises a
tool to design sustainable adaptation management strategies taking into
account the uncertainty in future GC conditions and their impacts. The
results show that GC scenarios produce significant increases in the
variability of flow budget components and in the salinity.
High-resolution ensemble projections and uncertainty assessment of regional climate change over China in CORDEX East Asia
Authors: Gu Huanghe , Yu Zhongbo , Yang Chuanguo , Ju Qin , Yang Tao , Zhang Dawei 
Published: May 2018

Abstract. An ensemble simulation of five regional climate models (RCMs) from the
coordinated regional downscaling experiment in East Asia is evaluated and
used to project future regional climate change in China. The influences of
model uncertainty and internal variability on projections are also
identified. The RCMs simulate the historical (1980–2005) climate and future
(2006–2049) climate projections under the Representative Concentration
Pathway (RCP) RCP4.5 scenario. The simulations for five subregions in China,
including northeastern China, northern China, southern China, northwestern
China, and the Tibetan Plateau, are highlighted in this study. Results show
that (1) RCMs can capture the climatology, annual cycle, and interannual
variability of temperature and precipitation and that a multi-model ensemble
(MME) outperforms that of an individual RCM. The added values for RCMs are
confirmed by comparing the performance of RCMs and global climate models
(GCMs) in reproducing annual and seasonal mean precipitation and temperature
during the historical period. (2) For future (2030–2049) climate, the MME
indicates consistent warming trends at around 1 ∘C in the entire
domain and projects pronounced warming in northern and western China. The
annual precipitation is likely to increase in most of the simulation region,
except for the Tibetan Plateau. (3) Generally, the future projected change in
annual and seasonal mean temperature by RCMs is nearly consistent with the
results from the driving GCM. However, changes in annual and seasonal mean
precipitation exhibit significant inter-RCM differences and possess a larger
magnitude and variability than the driving GCM. Even opposite signals for
projected changes in average precipitation between the MME and the driving
GCM are shown over southern China, northeastern China, and the Tibetan
Plateau. (4) The uncertainty in projected mean temperature mainly arises from
the internal variability over northern and southern China and the model
uncertainty over the other three subregions. For the projected mean
precipitation, the dominant uncertainty source is the internal variability
over most regions, except for the Tibetan Plateau, where the model
uncertainty reaches up to 60 %. Moreover, the model uncertainty increases
with prediction lead time across all subregions.
NONLINEAR VISCOELASTIC DISSIPATION IN VULCANIZATES CONTAINING CARBON BLACK AND SILANIZED SILICA HYBRID FILLERS

Published: May 2018

ABSTRACT
Different mechanisms of large-strain viscoelastic dissipation in vulcanizates containing carbon black or silanized silica and their synergistic effects in hybrid filler tread vulcanizates were investigated. In addition, the pure effects of fillers were examined while the degree of chemical cross-linking in the rubber matrix was similar in the vulcanizates. The results revealed that nonlinear viscoelastic loss modulus under strain-controlled dynamic tests, as a measure of dissipation mechanism, is high in both carbon black and silanized silica tread vulcanizates. However, a synergistic effect in reducing loss modulus was observed in the hybrid filler vulcanizates. Conversely, storage modulus in the vulcanizates containing more silanized silica is distinguishably higher and results in a lower loss factor representing load-controlled cyclic deformation of vulcanizates, such as in the heat buildup test. Both loss factor and heat build-up reduced nonlinearly as the amount of silanized silica increased in the vulcanizates, verifying the synergistic effect of hybrid carbon black–silanized silica filler in reducing dissipative mechanisms in large-strain dynamic loadings. This feature is highly favorable for the tire industry, where the lowering of viscoelastic dissipation in tread vulcanizates is of great importance.
INFLUENCE OF NANOFILLER ON THERMAL DEGRADATION RESISTANCE OF HYDROGENATED NITRILE BUTADIENE RUBBER
Authors: Saha Tuhin , Bhowmick Anil K. 
Published: May 2018

ABSTRACT
Studies on the degradation of elastomers and their prevention have become increasingly important in recent years because of stringent environmental conditions in many industrial applications. The reactive atomistic simulation was executed on a hydrogenated acrylonitrile-butadiene rubber (HNBR40) model compound composed of 40 monomer units. The reactive simulation was used to study the decomposition behavior of HNBR40, to visualize different pyrolysis products, and also to analyze the degradation mechanism of HNBR40. Ethylene, propylene, and acrylonitrile were observed as dominant products at lower temperature, and 1-butene was found at higher temperature. Pyrolysis–gas chromatography–mass spectrometry was used to verify the decomposition products obtained from the prediction of atomistic simulation. In this study, nanofillers, especially nanoclays and nanosilicas, were used to prevent degradation significantly. Restricted degradation by the nanofiller-reinforced rubber prolonged the durability. Furthermore, the reactive simulation was performed to understand thermal decomposition characteristics of the model compound in the presence of the nanofiller. The initial decomposition temperature, the final degradation temperature, and the rate of degradation improved to a great extent on the addition of the model nanosilica compound as obtained from the simulation studies. Moreover, the lifetime of nanoclay- and nanosilica-reinforced hydrogenated acrylonitrile–butadiene rubber was calculated by using thermogravimetric analysis, and its useful lifetime was compared with that of the pristine polymer in the application temperature range of 150 °C.
Meta-heuristic and RSM approach for Multi-objective Optimization of Plain Flow Refrigerant Vapor Condensation inside Tubes
Authors: Kumar Ravindra , Kumar Parmananad 
Published: May 2018

Condensers are extensively used heat exchangers in
automobiles and air conditioning systems. Optimization of heat transfer and
pressure drop inside condensers is an important area of concern for the designers.
In the present study, condensation characteristics inside smooth
horizontal tubes is optimized using teaching-learning based optimization (TLBO)
algorithm and response surface methodology (RSM). Refrigerant mass velocity
(G), vapor quality (x) and tube internal diameter (Di) are taken as
design parameters. Heat transfer coefficient (h) and pressure drop (ΔP) values of
refrigerants are calculated based on the mathematical models and served as
objective functions for RSM. The same mathematical models are applied to
formulate a multi-objective optimization problem with an aim to maximize heat
transfer coefficient and minimize pressure drop and is solved using TLBO. Two
different refrigerants have been considered to display the application of the
approaches. Of the two methods applied, TLBO seems to give better optimum
results.

Abstract
Three related analytical methods were developed and validated for the determination of pesticides in cannabis leaves, dried cannabis flowers, and cannabis oil. The methods follow the generic sequence of an acetonitrile extraction, followed by solid-phase extraction cleanup and analysis by HPLC-tandem mass spectrometry (HPLC-MS/MS), GC-MS/MS, and GC-MS. These methods were developed to accommodate sample quantity and lipid content of the different matrices. Validation at a spiking level of 0.01 μg/g was successful for 39 pesticides in cannabis leaves and 40 pesticides in cannabis oil, and at 0.02 μg/g for 32 pesticides in cannabis flowers, with the majority of analytes showing recoveries within the acceptable range of 70–130%. With these methods established, unannounced inspections of Canadian licensed producers of cannabis revealed that out of 144 samples collected, 26 showed the presence of unauthorized pest control products.
