Authors: Brown Nicole , Jafferani Aly , Pattharwala Vanessa 
Published: April 2018

The rhetoric of teaching in higher education is now placing more emphasis than ever on the student voice and on providing students with opportunities to collaborate with staff and take responsibility for their learning. This article is an example of a collaborative project between academic staff and students within the community of practice of trainee teachers; it describes their collaborative development of creative methods to deepen students' reflections. A brief section on the background and context of the course is followed by a short introduction to reflections. The paper then outlines how student feedback and work with students led to the development of creative and playful activities to foster students’ theoretical understanding and practical application of reflections. Subsequently, the participants in this project - two students and a member of staff - outline the main outcomes as they experienced them; they highlight the lessons learnt and the implications of their experiences for future practice. The study concludes with authorial thoughts about the nature of student-staff collaborations in this specific educational context.
By Design. Engaging Graphic Design Students in Curriculum Development
Authors: Moys Jeanne-Louise , Collier Joy , Joyce Diane 
Published: April 2018

To achieve this, we aimed to develop a new first-year module. As part of our continuing student collaboration process, we sought to take a partnership approach to the design of the module by inviting students to participate in a focus group to share their ideas about what a new module needed to cover and what forms of assessment they thought would be appropriate. Their ideas were then either adopted and built into the new module from the outset or applied , as relevant to other modules within the curriculum. The information shifted the emphasis and level of detail we built into the module planning. It also provided helpful guidance to early career colleagues involved in developing learning resources and assessment tasks for the module. The case study is being used to encourage colleagues across different disciplines to embed student engagement initiatives within the curriculum design process.

Abstract
In the budgeting of all major development projects, there is always a desire to capture the financial and operational opportunities of all new and existing technologies; however, this can be difficult if not proven to be viable in advance of the development campaign commencing. This leads to great difficulty in fully capturing potential savings in future financial planning. In a cost-sensitive market, a leading East Africa exploration and production operator recognized an opportunity to trial new technologies in the exploration and appraisal campaign phase in order to reduce well cost and risk, which could be directly translated to the development campaign feasibility model. A flat-time analysis was performed on historical data to benchmark the connection performance against relevant proxies. From this analysis, it was determined that there was room for improvement from both technology and existing practices. To improve the connection time on a technology basis, offset field resistivity data were modelled to determine the feasibility of the formations drilled to efficiently propagate a bi-directional electromagnetic signal. Once the modelled feasibility was deemed acceptable to deploy from a risk perspective, a systematic field-trial plan was developed to deliver proof of concept, which was followed by the second element, running the system to reduce connection time. After two successful proof-of-concept runs, the electromagnetic system facilitated a material reduction in connection time, which could then be applied to the development project economics. Whilst primarily focusing on technology-oriented connection improvements, there was also a systematic performance improvement from the human element on the rig floor owing to the performance initiative. The secondary benefit of successfully implementing the electromagnetic telemetry system was the increased data rate and the ability to transmit annular pressure data while the pumps were off, which provides valuable data to understand wellbore hydraulic behavior during pumps-off events. With conventional mud-pulse telemetry systems, the critical path is impeded to obtain these measurements, where annular pressure data is streamed to surface after the surface event (e.g., LOT / FIT, connection ballooning check, etc.). During these field trials, the downhole equipment complexity run in conjunction with the electromagnetic telemetry transitioned from basic gamma ray and pressure measurements to a quad-combo LWD string run in conjunction with a rotary steerable system.
Cluster Spacing Optimization for Horizontal-Well Fracturing in Shale Gas Reservoirs: Modeling and Field Application
Authors: Lin Ran , Ren Lan , Zhao Jinzhou 
Published: April 2018

Abstract
Multi-stage fracturing in horizontal well is the core technology for commercial exploitation of shale gas reservoir, in which the cluster spacing plays an important role to impact the fracturing performance—undersized cluster spacing might make the stimulated reservoir volume (SRV), activated by different hydraulic fractures, excessively overlap with each other, while oversized cluster spacing might leave unstimulated regions between neighboring hydraulic fractures; in either case the fracturing would be inefficient. However, most current cluster spacing design methods are imperfect without a reliable SRV estimation model. This paper established a numerical model to estimate the SRV by simulating four key processes during multi-stage fracturing—hydraulic fractures propagation, formation stress changing, reservoir pressure lifting, and natural fractures failure. Then, based on this SRV model, an optimization method for cluster spacing was proposed and applied in Fuling shale gas field in Southwest China. We analyzed the influence of geological conditions and fracturing parameters on the optimal cluster spacing, and drew the reference charts for cluster spacing design in Fuling gas field. This research developed an effective cluster spacing optimization method, reduced the uncertainty in cluster spacing design, and provided some new insights on the optimal design of multi-stage fracturing in horizontal shale gas well.
Real-Time Downhole Measurements During Coiled Tubing Campaign Brings Wells Back to Life
Authors: Keong Azwan , Sorensen Christoffer , Andaloussi Youssef 
Published: April 2018

Abstract
Coiled tubing (CT) was used on a field on the Norwegian continental shelf to intervene in four separate wells. The campaign objectives were to restore injectivity to two injector wells, prepare a well for plugging and abandonment (P&A), and bring a newly drilled well onto production. The use of CT was a prerequisite because previous wireline interventions had failed to reach target depths due to ingress of fill into the wellbore.
Three main challenges were faced during that campaign: demanding cleanout conditions, precision required on downhole weights, and critical perforations. The demanding cleanout conditions were due to the large completions and sensitive formations, which required accurate control of slighty underbalance conditions. The precise measurement of downhole weight and torque was required to effectively manage milling operations and accurately cut a hanger. Finally, the perforations required a depth accuracy within 0.5 m of the target depth, accuracy that was beyond the limits of what surface depth measurements can provide. Real-time downhole measurements quickly appeared as the common denominator to address all those challenges at once.
To address the demanding cleanout conditions, real-time measurements of downhole pressures allowed controlling the pumping conditions at depth, whilst still allowing high pumping rates. This enabled handling high pumping rates, so the cleanouts could be performed effectively. To obtain precise downhole weights during milling and cutting operations, the exact downhole weight on the bottomhole assembly (BHA) and torque was monitored, which, in turn, opened possibilities for adjusting and optimizing the mill and motor use during the operations. For critical perforations, a selective activation firing head was used along with the full array of pressure, temperature, and depth control modules, which allowed multiple guns to be positioned precisely on depth and separately fired in a single run.
The application of real-time downhole measurements resulted in objectives being met. Increased injectivity was achieved, while rig days were saved with the P&A preparations.
Wettability Estimation by Oil Adsorption Using Quartz Crystal Microbalance with Dissipation QCM-D
Authors: Erzuah Samuel , Fjelde Ingebret , Voke Omekeh Aruoture 
Published: April 2018

Abstract
The wetting properties of the reservoir rocks are governed by the tendency of the individual minerals constituting the reservoir rock to adsorb oil during crude oil/brine/rock (COBR) interactions. To explore the oil adhesion kinetics during COBR interactions, one approach is to assess the oil adhesion tendencies of the individual minerals. The aim of this presented study was to characterize the wettability by determining the oil adhesion tendencies of the minerals using Quartz Crystal Microbalance with Dissipation (QCM-D). The kinetics of the mass (Δmads) and the thickness (Δt) of the adsorbed film were modelled mathematically using the Sauerbrey relation with the QCM-D output as input. In addition, we present Surface Complexation modelling (SCM) evaluation of possible electrostatic linkages of the studied COBR system.
The kinetics of oil adsorption during COBR interactions were prominent during Formation Water (FW)/Stock Tank Oil (STO)/FW injection sequence with kaolinite sensor as compared to that of quartz. This was depicted by the relatively high change in the FW frequency signal (Δf) before and after the injection of STO with kaolinite sensor as compared to quartz. Negligible change in the frequency signal (Δf≈ 0) was observed during the various injection sequence with quartz sensor. This suggested that minor adsorption has taken place, thus confirming the hydrophilic nature of the quartz sensor. The mathematical modelling of the thickness (Δt) and the mass (Δmads) of the adsorbed film also reveals that kaolinite is more oil wet than quartz. This is portrayed by the relatively high magnitude of the adsorbed oil on kaolinite (Δt = 6nm - 14nm and Δm = 1600ng - 3500ng). The SCM results also confirm negligible (≈ 0.008) electrostatic pair linkage for the quartz sensor as compared to kaolinite (≈ 0.3). This shows that the tendency for oil to be adsorbed onto kaolinite sensors were relatively high as compared to quartz. The electrostatic pair linkages reveal that the dominant electrostatic pair linkage existing between the mineral- brine and the oil-brine interface was cation bridging by divalent cations such as Ca2+ and Mg2+. Hence, it was not surprising that the FW/STO/FW injection sequence for all the three (3) methods were relatively oil-wet as compared to similar sequence of optimum LSW composition. This was attributed to the abundance of Ca2+ and Mg2+ to bridge the two negatively charged surfaces in the former than in the latter.
Systematic Use of Tidal Effects for Reservoir Appraisal and Well Integrity Monitoring in a Near-Coast Onshore Environment
Authors: Hailstone Julien 
Published: April 2018

Abstract
Tidal effects in wells have been observed for millennia and have been analysed since the 1970s, following the introduction of high-resolution pressure gauges. Tidal effects are usually more obvious offshore and many papers focus on offshore wells with large tidal signals. This paper demonstrates that pressure changes caused by ocean tides are detectable in near-coast land wells and that, with careful analysis and processing, provide valuable additional information for reservoir characterisation.
This paper uses a set of observations from multiple near-coast land wells with extended pressure histories acquired as part of campaign of production and interference testing for reservoir characterisation purposes. These pressure records have variable tidal signal and data quality. A variety of methods have been published to smooth tidally influenced pressure data and extract or remove the tidal component. These different tidal filtering techniques are tested on real data, and a preferred data processing procedure is selected appropriate for the large quantity and variable quality of data in the study area. The methodology allows data from multiple wells to be quickly processed and consistently screened.
This paper gives examples of tidal behaviour in selected wells and compares the results across multiple wells in the study area to show how identification of subtle tidal effects is useful for:
Field appraisal of a saturated oil-rim with gas cap by examining differences in tidal amplitude in wells in different parts of the field. Estimation of critical gas saturation by comparing tidal amplitudes before and after an extended well test. Monitoring well integrity in a producing field by tidal analysis of annular pressures.
The paper also recommends a reservoir surveillance programme to obtain useful tidal data in onshore wells.
This paper will be useful to engineers attempting to find and interpret subtle tidal data, instead of simply removing it. It recommends a systematic approach for using tidal data in wells where tidal signals are small and/or gauge resolution is poor, based on experience with real data with variable data quality. It also provides a case study to show the value and practical application of a surveillance programme to identify tidal data in near-coast land wells.
Assessment of the potential contribution of alternative water supply systems in two contrasting locations: Lilongwe, Malawi and Sharm El-Sheikh, Egypt

Published: April 2018

Abstract
Growing water demand poses a challenge for supply. Poor understanding of alternative sources can hamper plans for addressing water scarcity and supply resilience. The potential of three alternative supply systems in Lilongwe, Malawi and Sharm El-Sheikh, Egypt are compared using a fast, data-light assessment approach. Lilongwe water supply is based on unsustainable use of source water, while Sharm depends primarily on desalination. Both locations experience shortages due to poor system performance and service inequity. Alternative supply systems are shown to potentially contribute to supply augmentation/diversification, improving service and system resilience. There are considerable seasonal variations to consider, especially regarding storage of water. Social preferences could limit the uptake/demand for alternative water. One important conclusion is the value in addressing public perceptions of alternative systems, and assessing water end use in order to site systems appropriately. Other issues surround financing, encouraging uptake and addressing institutional/governance aspects surrounding equitable distribution. A further consideration is whether demand reductions might yield shorter-term improvements in performance without the need to institute potentially expensive alternative water strategies. Reducing non-revenue water is a priority. Such measures should be undertaken with alternative supply enhancement to reduce inequity of supply, improve system performance and increase resilience to future changes.
Effect of boundary conditions on the performance of a dropshaft with an internal divider
Authors: Wei Jiafang , Ma Yiyi , Zhu David Z. , Zhang Jian 
Published: April 2018

Abstract
Dropshafts with an internal divider for air circulation are proposed to reduce air entrainment in plunging type dropshafts. Dropshafts typically operate under a pressurized downstream condition and with limited air supply from the top. In this study, experiments were conducted to investigate the performance of the dropshaft with an internal divider under different downstream conditions and air inlet conditions. From the experiments, a pressurized downstream condition would increase the air pressure in the dropshaft, reduce the outside air entrainment while increase the internal air circulation. Reducing the size of the air inlet would decrease the air pressure, meanwhile cause an increase in internal air circulation and a reduction in outside air entrainment. A dimensionless parameter of ‘effectiveness factor’ was also proposed to measure the effectiveness of the internal air circulation on reducing the outside air entrainment. This study considers the performance of the dropshaft with a divider under the conditions close to real situations, which is important to its design and application.
Translational Research: A Future Strategy for Managing Squamous Cell Carcinoma of the Head and Neck?

Published: April 2018

Background:
Squamous Cell Carcinoma of the Head and Neck (SCCHN) are neoplasms arising from
the epithelium of the first aero-digestive tract. They are very heterogeneous both clinically and biologically.
Classic and well acknowledged risk factors are alcohol and tobacco consumption and other forms of smokeless
tobacco assumption, although lately the incidence of Human Papilloma Virus (HPV)-related SCCHN is rapidly
increasing. HPV-related tumors are very different from their alcohol and tobacco-associated counterpart, as they
show strong chemo and radio sensitivity and thus can often be treated with conservative treatment strategies.
Moreover, peculiar biologic features characterize HPV-related tumors, such as wild type TP53, low expression
of Epidermal Growth Factor Receptor (EGFR), wild type CCND1 and high expression of P16. In contrast,
alcohol and tobacco related SCCHN show opposite features, together with higher number of chromosomal and
genetic abnormalities, conferring them chemo and radio resistance.

Methods:
We have performed a narrative review of the PubMed database with the aim to study the mutational
landscape of SCCHN.

Results:
Several lines of evidence support the existence of at least two genetically different types of SCCHN,
one virus-related and the other alcohol and/or tobacco-related, characterized by both clinical and biological
opposite features. Virus related SCCHN are very chemo and radiosensitive, so suitable for organ preserving
strategy, which in the near future may be induction chemotherapy followed by association of chemotherapy and
underpowered radiotherapy. Alcohol and tobacco related SCCHN are themselves strongly heterogeneous and
can be divided in different entities on the basis of the “Driver” genetic aberration, responsible for carcinogenesis.
The most frequently mutated genes in alcohol and tobacco-related SCCHN are TP53, NOTCH1, CCND1,
CDKN2A, EGFR and PI3KCA.

Conclusions:
Virus-related SCCHN can be managed with chemo-radiotherapy. Alcohol and tobacco-related
tumors should be further characterized on the basis of their “Driver Mutations” in order to select effective targeted
therapies.
Janowe wyznania wiary w ujęciu Prospera Grecha

Confessions of faith in the New Testament are the Early Church’s reply to the apostolic kerygma, which centre was Jesus and His saving work. The John’s Tradition includes many texts, which in their literature structure and theological content unmistakably indicate the confession of faith. In the Fourth Gospel and John’s Epistels, Prosper Grech has distinguished thirty-two text groups, which can be called formulae of faith in strict sense. The author has classified the formulae according to the following criteria:– verbs that introduce confessions,– Christological titles,– Jesus’ work,– Sitz im Leben of formulae.The Johannine Tradition does not include the formulae on Jesus’ Passion and Death which are so frequent in St. Paul and the Acts of the Apostles because the fourth evangelist represents the high Christology. His ideas are focusing on Incarnation, Revelation and Salvation with a universal dimension. Presence of so many homologies in the Writings of John proves that in the Early Christian era the Christological ideas were developing. In the future, the formulae of faith will contribute to the Credo of the Church.
Mobile Decision Support Tool for Emergency Departments and Mass Casualty Incidents (EDIT): Initial Study (Preprint)
Authors: Boltin Nicholas , Valdes Diego , Culley Joan M. , Valafar Homayoun 
Published: April 2018

BACKGROUND

Chemical exposures pose a significant threat to life. A rapid assessment by first responders and emergency nurses is required to reduce death and disability. Currently, no informatics tools exist to process victims of chemical exposures efficiently. The surge of patients into a hospital emergency department during a mass casualty incident creates additional stress on an already overburdened system, potentially placing patients at risk and challenging staff to process patients for appropriate care and treatment efficacy. Traditional emergency department triage models are oversimplified during highly stressed mass casualty incident scenarios in which there is little margin for error. Emerging mobile technology could alleviate the burden placed on nurses by allowing the freedom to move about the emergency department and stay connected to a decision support system.

OBJECTIVE

This study aims to present and evaluate a new mobile tool for assisting emergency department personnel in patient management and triage during a chemical mass casualty incident.

METHODS

Over 500 volunteer nurses, students, and first responders were recruited for a study involving a simulated chemical mass casualty incident. During the exercise, a mobile application was used to collect patient data through a kiosk system. Nurses also received tablets where they could review patient information and choose recommendations from a decision support system. Data collected was analyzed on the efficiency of the app to obtain patient data and on nurse agreement with the decision support system.

RESULTS

Of the 296 participants, 96.3% (288/296) of the patients completed the kiosk system with an average time of 3 minutes, 22 seconds. Average time to complete the entire triage process was 5 minutes, 34 seconds. Analysis of the data also showed strong agreement among nurses regarding the app’s decision support system. Overall, nurses agreed with the system 91.6% (262/286) of the time when it came to choose an exposure level and 84.3% (241/286) of the time when selecting an action.

CONCLUSIONS

The app reliably demonstrated the ability to collect patient data through a self-service kiosk system thus reducing the burden on hospital resources. Also, the mobile technology allowed nurses the freedom to triage patients on the go while staying connected to a decision support system in which they felt would give reliable recommendations.
