Transitioning from Rig to Vessel Based Interventions to Maximize Economic Recovery
Authors: Avery Mike , Morris David , Morgan Tony , Manson Greg , Gillespie David 
Published: March 2021

Abstract
As energy markets evolve, the supply mix diversifies, and the push for a net zero energy system accelerates, the competitiveness of oil and gas has become increasingly important. A focus upon the total cost of ownership across the field lifecycle has begun to emerge as a driving factor within subsea oil and gas project evaluation, with greater emphasis on cost-effective operations. Acknowledging that the life of field begins within the engineering, procurement, construction, and installation phase of a project allows the operator to influence through life activities to greatest effect and achieve a balanced optimization of capital and operational expenditure.
Intervention is a key activity for maintaining and optimizing a subsea wells performance, from initial installation, through the producing life, and finally during decommissioning. As completion technologies continue to evolve, opportunities emerge for optimization of the systems used to intervene upon subsea wells. One of the largest areas of opportunity is the simplification of a technique to permit operations from a more efficient rig or vessel. This paper explores some of the solutions available today which allow historically rig based activities to be performed from vessels. These include riser based intervention systems, hydraulic intervention solutions, well abandonment technologies, and subsea workover control systems.
An evaluation of the presented techniques against alternative approaches is shared, to aid the reader in selecting the optimal solution for an application. Guidance is provided to assist in identifying the key decision criteria, complete with the capabilities and limitations of each solution.
The conclusions identify that designing a subsea production system with the flexibility to accommodate life of field activities can deliver reduced total cost of ownership to operators. A key part of this is consideration of optimized intervention techniques which can leverage simpler vessels for deployment and operation. By reducing the vessel specification, broad benefits can be realized including reduced asset day rate, reduced operational duration, and increased asset availability globally. This permits improved scheduling and reduced mobilization costs, in some cases enabling intervention activities which otherwise would not be economical.
The Effect of Metformin on Aminotransferase Levels, Metabolic Parameters and Body Mass Index in Nonalcoholic Fatty Liver Disease Patients: A Metaanalysis
Authors: Hu Haibo , Wang Junjie , Li Xi , Shen Lujun , Shi Danhe , Meng Juanjuan 
Published: March 2021

Background:
Nonalcoholic fatty liver disease (NAFLD) is one of the most common reasons for the
increase in serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. Moreover, liver-
associated death is approximately 10 times higher in patients with NAFLD than in common individuals. In
theory, NAFLD is a kind of metabolic syndrome that manifests in the liver, and insulin resistance plays an important
role in it. Therefore, drugs that improve insulin sensitivity may be effective for NAFLD.

Objective:
The aim of this study was to evaluate the effect of metformin treatment on aminotransferase levels,
metabolic parameters and body mass index in NAFLD patients via a meta-analysis of clinical trials.

Methods:
A comprehensive search on PubMed, EMBASE, the Web of Science and the Cochrane Central Register
of Controlled Trials was performed for randomized controlled trials (RCTs) on the effect of metformin treatment
on aminotransferase levels, metabolic parameters and body mass index in NAFLD patients. Serum hepatic
enzyme, lipid, glucose and insulin levels, homeostasis model assessment-insulin resistance (HOMA-IR) index
and body mass index (BMI) at different follow-up points exhibited desirable outcomes. The final search
was performed in January, 2021.

Results:
In total, 10 RCTs with 459 patients were included. Compared with controls, metformin could effectively
reduce serum fasting glucose and insulin levels and the HOMA-IR index in NAFLD patients at the 6-month
follow-up. In addition, metformin could clearly reduce the serum ALT and HOMA-IR index at the 12-month
follow-up. Although metformin was found to be effective in managing lipid metabolism and controlling BMI in
NAFLD patients compared with that at baseline, the effect was similar to that in controls. In addition, the speed
of metformin treatment seemed to be slower than that of controls.

Conclusion:
Compared to the controls, metformin could effectively reduce the serum fasting glucose and insulin
levels and the HOMA-IR index in NAFLD patients at the 6-month follow-up and ALT and the HOMA-IR
index at the 12-month follow-up.
Molecular Evaluation of Exon 8 Cystathionine rs5742905T T>C Gene Polymorphism and Determination of its Frequency, Distribution Pattern, and Association with Susceptibility to Coronary Artery Disease in the North Indian Population
Authors: Sumi Mamta P. , Guru Sameer A. , Mir Rashid , Sahu Samantak , Bhat Musadiq A. , Girish M.P. , Saxena Alpana 
Published: March 2021

Background:
The protein coded by the cystathionine β synthase (CBS) gene acts as a catalyzer
and converts homocysteine to cystathionine. Impairment of the CBS gene leads to homocystinuria
by cystathionine β synthase deficiency which is linked to Coronary Artery Disease. A
number of polymorphisms studies have been performed on the cystathionine β synthase gene. In
the current study, we planned to analyze the influence of CBS T833C gene polymorphism(exon 8
cystathionine rs5742905T T>C), its association with Coronary Artery Disease development, and its
progression in the north Indian population.

Materials and Methods:
The present study comprises 100 angiographically confirmed CAD patients
and 100 age and sex-matched healthy controls. A total of 50% or more luminal stenosis at
one major coronary artery was considered for the inclusion criteria of the cases. The investigation
of T833C polymorphism in the CBS gene was performed by PCR- RFLP technique.

Result:
As a result, we found that homozygous mutant (CC) and heterozygous (TC) genotypes of
CBS T833C gene polymorphism were significantly higher in CAD patients than in healthy subjects.
We also observed a substantially increased CAD risk in dominant, codominant inheritance,
and allele-specific models for the CBS T833C gene polymorphism. We analyzed the differential
distribution with respect to disease severity, but there was no significant association (p=0.96).

Conclusion:
In conclusion, this study demonstrates that CBS T833C gene polymorphism plays a
key role in developing coronary artery disease and its progression.

Authors: Reddy M.S. Prashanth , Raju Hemadri P. , Banapurmath Nagaraj R. , Meti Vinod Kumar V. , Patil Arun Y. 
Published: March 2021

Aims:
Al7075 is a well-defined alloy for its excellent physical and mechanical behavior,
such as high strength, toughness, and low density. To reach the expectations of the automobile and aerospace
applications, the properties of Al7075 alloy have to be improved by reinforcing nano-sized
Al2O3 particles.

Objectives:
Synthesis and characterization of the Al7075 alloy reinforced with Al2O3 nano particles for
different structural engineering applications.

Methods:
In this present work, nano-sized Al2O3 particles were added and dispersed homogeneously
using a stir casting technique. AA7076/Al2O3 composites were prepared by varying wt.% percent of
Al2O3 reinforcement particles (0.75, 1, 1.25, 1.5. 1.75 and 2 wt.% (weight-percentage)).

Results:
The SEM micrographs reveal the homogeneous distribution of Al2O3 reinforcements along the
grain boundaries of the Al7075 matrix material. The experimental test results showed that the addition
of Al2O3 reinforcements and the mechanical properties of the Al7075/Al2O3 composite improved as
compared to the Al7075 matrix material.

Conclusion:
The composite with 1.5 wt.% Al2O3 showed higher strength and hardness as compared to
other reinforcements.
Conceptualizing Illness: Nodding Syndrome in Northern Uganda
Authors: Van Bemmel Karin 
Published: March 2021

This paper presents an ethnographic study of conceptualizations of nodding syndrome (NS) in Uganda. NS is a poorly understood condition characterized by repetitive nodding of the head, mental retardation and stunted growth, which affects thousands of children in northern Uganda, South Sudan and Tanzania. Although extensive research for causative agents has been conducted, no convincing single cause has been reported. This study establishes an understanding of different representations of NS and argues that the episodes of head nodding are related to the socio-political body in which they are manifested. Three interwoven approaches towards NS take main stage whereby the syndrome is presented as a biomedical, spiritual and/or political problem. The conceptualizations are linked to different notions of healing and affected families combine various forms of therapy. Through the examination of different narratives, this study disrupts the idea of a singular perspective on illness and pleads for a focus on motion and plurality.

Beyond Silencing the Guns: China and a new Metaphor for Peace and Security in Africa
Authors: Velthuizen Andreas 
Published: March 2021

The author presents the tentative results of ongoing research into a new paradigm for peace and security in Africa. The empirical foundation of the research is the result of a triangulation of research methods that involved literature study, reflexive journaling and thematic analysis. The discussion aims to determine how China can contribute to the renewal of the African Peace and Security Architecture (APSA). The aim is achieved by discussing and analysing the current APSA, including the challenges experienced, as well as the policy commitments and security activities of China in Africa. The research concludes that China is building a military intervention capacity to protect its interests in Africa. However, a new metaphor is needed that will bring solutions to the peace and security challenges of Africa. In this regard China can play an important role in assisting the APSA to focus on issues such as social transformation, capacity building for socio-economic development, and education aimed at peace and security.

Published: March 2021

Background
With the growing adult population using electronic hearing devices such as cochlear implants or hearing aids, there is an increasing worldwide need for auditory training (AT) to promote optimal device use. However, financial resources and scheduling conflicts make clinical AT infeasible.

Objective
To address this gap between need and accessibility, we primarily aimed to develop a mobile health (mHealth) app called Speech Banana for AT. The app would be substantially more affordable and portable than clinical AT; would deliver a validated training model that is reflective of modern techniques; and would track users’ progress in speech comprehension, providing greater continuity between periodic in-person visits. To improve international availability, our secondary aim was to implement the English language training model into Korean as a proof of concept for worldwide usability.

Methods
A problem- and objective-centered Design Science Research Methodology approach was adopted to develop the Speech Banana app. A review of previous literature and computer-based learning programs outlined current AT gaps, whereas interviews with speech pathologists and users clarified the features that were addressed in the app. Past and present users were invited to evaluate the app via community forums and the System Usability Scale.

Results
Speech Banana has been implemented in English and Korean languages for iPad and web use. The app comprises 38 lessons, which include analytic exercises pairing visual and auditory stimuli, and synthetic quizzes presenting auditory stimuli only. During quizzes, users type the sentence heard, and the app provides visual feedback on performance. Users may select a male or female speaker and the volume of background noise, allowing for training with a range of frequencies and signal-to-noise ratios. There were more than 3200 downloads of the English iPad app and almost 100 downloads of the Korean app; more than 100 users registered for the web apps. The English app received a System Usability Scale rating of “good” from 6 users, and the Korean app received a rating of “OK” from 16 users.

Conclusions
Speech Banana offers AT accessibility with a validated curriculum, allowing users to develop speech comprehension skills with the aid of a mobile device. This mHealth app holds potential as a supplement to clinical AT, particularly in this era of global telemedicine.
The Effect of Sensor Placement and Number on Physical Activity Recognition and Energy Expenditure Estimation in Older Adults: Validation Study
Authors: Davoudi Anis , Mardini Mamoun T , Nelson David , Albinali Fahd , Ranka Sanjay , Rashidi Parisa , Manini Todd M 
Published: March 2021

Background
Research has shown the feasibility of human activity recognition using wearable accelerometer devices. Different studies have used varying numbers and placements for data collection using sensors.

Objective
This study aims to compare accuracy performance between multiple and variable placements of accelerometer devices in categorizing the type of physical activity and corresponding energy expenditure in older adults.

Methods
In total, 93 participants (mean age 72.2 years, SD 7.1) completed a total of 32 activities of daily life in a laboratory setting. Activities were classified as sedentary versus nonsedentary, locomotion versus nonlocomotion, and lifestyle versus nonlifestyle activities (eg, leisure walk vs computer work). A portable metabolic unit was worn during each activity to measure metabolic equivalents (METs). Accelerometers were placed on 5 different body positions: wrist, hip, ankle, upper arm, and thigh. Accelerometer data from each body position and combinations of positions were used to develop random forest models to assess activity category recognition accuracy and MET estimation.

Results
Model performance for both MET estimation and activity category recognition were strengthened with the use of additional accelerometer devices. However, a single accelerometer on the ankle, upper arm, hip, thigh, or wrist had only a 0.03-0.09 MET increase in prediction error compared with wearing all 5 devices. Balanced accuracy showed similar trends with slight decreases in balanced accuracy for the detection of locomotion (balanced accuracy decrease range 0-0.01), sedentary (balanced accuracy decrease range 0.05-0.13), and lifestyle activities (balanced accuracy decrease range 0.04-0.08) compared with all 5 placements. The accuracy of recognizing activity categories increased with additional placements (accuracy decrease range 0.15-0.29). Notably, the hip was the best single body position for MET estimation and activity category recognition.

Conclusions
Additional accelerometer devices slightly enhance activity recognition accuracy and MET estimation in older adults. However, given the extra burden of wearing additional devices, single accelerometers with appropriate placement appear to be sufficient for estimating energy expenditure and activity category recognition in older adults.
