Authors: Abd El Aty Abeer , Alharbia Reem , Soliman Ahmed 
Published: October 2020

Two levels Plackett-Burman experimental design was employed to screen the main factors that significantly affect the synthesis of bioactive silver nanoparticles. Scenedesmus obliquus ethanol extract, Scenedesmus obliquus dried algal powder and Spirulina platensis aqueous extract were the most favorable reducing and capping agents. Also the high pH value (10), rpm (150), high concentration of AgNO3 (4 mM) and dark conditions had the highest significant influence on biosynthesis of active nanoparticles. Characterizations of the formed AgNPs were approved by UV–Visible Spectroscopy, Transmission Electron Microscopy and Fourier Transform Infrared spectroscopy. The nanoparticles were varied in sizes and shape that ranged between 2.83 and 27.17nm, depending on the organism used and the method of biosynthesis. Valuable inhibitory effects were showed by all bio-synthesized nanoparticles against four tested Gram- positive and Gram- negative bacteria, except that formed by Spirulina platensis powder. Moreover, the nanoparticles exhibited wide range of antifungal activities. AgNPs prepared from ethanol extract of Spirulina platensis was the most active against HepG2 and MCF-7 cell lines, with IC50values 62.1 and 56.2 ug/mL, respectively. The obtained results, indicated the advantages of AgNPs from microalgae and possible industrial applications as a source of antifungal, antibacterial, and antitumor formulation.

Naming and framing ecological distress
Authors: Wardell Susan 
Published: October 2020

]We are living in a time of massive anthropogenic ecological and climatic shifts. Awareness of these changes and their effects on human lives is increasing, with recognised impacts on mental health. At present, a variety of different terms exist to describe ecological change-related distress. They range from the philosophical to the clinical, and are already beginning to form part of professional practice, as well as popular discourse, with prescriptive implications. In this piece, I explore some of the different names and frames for ecological distress by drawing on a sample of 30 online articles, blogs, and videos, and bringing these into dialogue with scholarly literature. My purpose is to open up a conversation about how medical anthropologists might attend to the meaning-making processes that surround ecological distress and (individual, institutional, and political) responses to it.
COMPARISON OF NONINVASIVE CENTRAL VENOUS PRESSURE MEASUREMENT METHODS: INTERNAL JUGULAR VEIN VERSUS VENA CAVA INFERIOR
Authors: ÖZLÜER Yunus Emre , KAPÇI Mücahit 
Published: October 2020

Objective
Central venous pressure measurement is an effective
method to detect the volume status of the patients.
However, life-threatening complications such as
pneumothorax may occur. We assume that ultrasonographic
measurements may be used as a surrogate
of invasive central venous pressure.
Materials and Methods
Our study has been conducted between January
2015-January 2016 on 81 patients who were over
the age of 18 and to whom a central venous catheter
has been placed in the internal jugular vein (IJV)
in our Emergency Intensive Care Unit. The height of
the blood column in the internal jugular vein, internal
jugular vein collapsibility index (IJV-CI) and the caval
index (CI) of vena cava inferior have been measured
by ultrasound. Then, invasive central venous pressure
(CVP) has been measured and the patients were
separated into two groups as low CVP and normal
CVP groups and statistically significance was sought
between groups in regard of these three methods.
Results
The mean age was 68.58±13.33 years. Fifty-four of
the patients (66.6%) were male. Forty-six patients
(56.8%) were mechanically ventilated. Low CVP
group consisted of 62 patients (76.5%). Mean invasive
CVP was 4.83±4.26 mmHg. There were significant
correlations between IJV-CI and invasive CVP along
with the CI (r=-0.267, p=0.016 and r=0.319, p=0.04,
respectively), IJV height method and CI as well as
invasive CVP measurement (r=-0.231, p=0.03 and
r=0.357, p=0.01, respectively). The CI did not yield
any correlation between invasive CVP measurement
(r=-0.010, p=0.368).
Conclusion
Noninvasive central venous pressure measurement
methods may be used as a surrogate for invasive
central venous pressure levels. The IJV-CI may be
a useful tool to estimate CVP. Measurements of IJV
yields better results than the measurements from
vena cava inferior (VCI) especially in volume depleted
patients.
THE USE OF THORACOACROMIAL ARTERIAL TRUNK AND CEPHALIC VEIN SYSTEM WITH DIFFERENT MODALITIES INCLUDING CHIMERIZATION OF FREE FLAP IN DIFFICULT SITUATIONS AS THE RECIPIENT VESSELS
Authors: ALTUNTAŞ Selman Hakkı , USLUSOY Fuat , YAVUZ Dudu Dilek , AYDIN Asım 
Published: October 2020

Objective
We aimed to remind surgeons of the presence of the
thoracoacromial arterial trunk and cephalic vein (TATCV)
for a comfortable and reliable free flap transfer
to the head, arm, and trunk, in case the mainstream recipient vessels of these regions pose some inconveniences
due to previous surgery, radiotherapy, or
trauma.
Material and Methods
Eight cases of trauma or tumor involving the head and
neck or upper extremity, treated with free tissue transfer
in which this vascular system was used with different
modalities, were reviewed retrospectively.
Results
This vascular system proved to be reliable in all cases.
It enabled chimerization with the pectoral flap. It was
used in six patients for head and neck reconstructions
and in two upper extremity restrorations. Switching
the anastomoses to TAT-CV site and cephalic vein
transposition were found to be rapid and reliable methods
to rescue a flap with compromised circulation.
Discussion
Although anatomically well known by many reconstructive
surgeons, its ease of dissection, consistency,
supply of branches of differing caliber, and strategic
location is not adequately appreciated. Moreover, in
cases of pectoralis major flap transfer in which additional
tissue is required, this vascular system is already
there to receive it.

On the basis of the new method it is possible to obtain mass data on the geochemistry of light lanthanides in soils.
Vapor-Liquid Equilibria and Diffusion of CO2/n-Decane Mixture in the Nanopores of Shale Reservoirs

Published: October 2020

Abstract
Numerous laboratory tests on the Northern American shale plays have observed a large number of nanopores. Because of the pore-proximity effect, the vapor-liquid phase equilibrium and transport performance of fluids in nanopores differ significantly from that observed in PVT cell. In recent years, CO2 huff-and-puff has been widely applied to unlock the shale reservoirs. But on account of the high adsorption selectivity of CO2, after the injection of CO2, the original vapor-liquid equilibria of hydrocarbons is changed. The purpose of this study is to predict the phase behavior and diffusion of the CO2/n-decane mixtures in the nanopores. The Peng-Robinson (PR) equation of state is combined with Young-Laplace equation to calculate the phase-composition diagram at the presence of capillary pressure. The equilibrium molecular dynamics simulations (MDS) are also conducted to study the phase behavior, and the number density profiles of different molecules are calculated. Then, based on the discussion of phase behavior, a series of equilibrium MDS runs are carried out to calculate the self-diffusion coefficients of CO2, n-decane, and all fluid molecules. For each MDS with a different CO2 mass fraction, the two types of fluid molecules are thoroughly mixed, the conditions of pore size and temperature are consistent with those in the phase behavior studies.
Results indicate that considering the capillary pressure, when the mass fraction of CO2 is less than 40%, the bubble point suppression is more clearly shown in the phase envelope. The number density profiles of n-decane molecules show the apparent characteristics of adsorption layers. As the mass fraction of CO2 molecules increases, the self-diffusion coefficients of CO2, n-decane, and their mixtures all increase. The self-diffusion coefficients of CO2 molecules are higher than that of the n-decane molecules, and the diffusion coefficients of the entire fluid system are somewhere in between. Appropriate CO2 injection into shale oil reservoirs can not only reduce the confinement-induced bubble point suppression but also improve the flow behavior of oil in nanopores. This study can shed some critical insights for the vapor-liquid phase equilibria of confined fluids in nanopores and provide sound guidelines for the application of CO2 huff and puff in shale reservoirs.
Lessons Learned in Developing Human Capital for The Oil and Gas Industry in Kazakhstan

Published: October 2020

Abstract
The World Economic Forum's (WEF) Human Capital initiative has been implemented at Satbayev University (SU), Almaty, Kazakhstan for the last two years. Participating in this effort are Chevron, Eni, Shell, and the Colorado School of Mines (Mines). This paper assesses the effectiveness of project components, such as industry guest lectures, summer internships, and program improvement and provides lessons learned for human resources development initiatives.
This paper utilizes the qualitative research method in which data are collected through focus group interviews. Key participants of the study include students enrolled in the WEF program and faculty members. Moreover, the interviewing process involves students that are not part of the WEF program as a control group to measure progress made with additional benefits.
The article explains major challenges of talent development in higher education institutions. It has been determined that the local specifics, especially students' socio-economic and educational background, play an important role on future academic success. For example, students encountered difficulties with understanding course materials and industry guest lectures, which is attributed to English language barriers. Yet, select students have had strong success in the upper-intermediate and above levels. Students' internships revealed that summer experience has greatly strengthened their practical knowledge and skills, opened eyes to industry settings, and more importantly, influenced better planning of career paths. Students reported internships not only provided an industry outlook but also perspectives of continuing graduate studies. It is noted that workforce development requires sufficient faculty development in a case of scarce human resources. The competent and adequate faculty, especially in petroleum engineering (PE), is a prominent problem in most developing oil and gas countries. This issue was articulated among stakeholders, and the project results demonstrate the successful case of company support to raise professional competencies of SU faculty.
This paper covers the human capital development challenges within the WEF project framework, and based on scientific evidence, further elucidates the project-specific tools to propagate similar initiatives around the world. Kazakhstan's experience, as a former Soviet Union state, brings useful suggestions to transform higher education talent development to match the industry-wide standards. It is highlighted that an effective industry-academia collaboration develops from shared visions, values, and goals.

Abstract
The authors have developed an algorithm that combines simple, proven, analytical work tools. The algorithm allows one to quickly update the potential, taking into account geological and technical factors, assess risks, estimate current recoverable reserves, incremental oil production, and economics for each well. The purpose of the work is to reduce routine labor costs when searching for and selecting wells, to rank the entire list of relevant candidates, to increase the share of successful operations, as well as to increase incremental oil production by accelerating well optimization with minimal risk. A pilot project helped to improve the success rate of optimization jobs from 75 to 89%, and increase specific incremental oil production by 57% in comparison with the previous year. The tool can also be used for auditing decisions as a retrospective.
Evaluation of A Cyclic Water Injection Program Using A Combination of Artificial Intelligence and Reservoir Physics
Authors: Calad Serrano Carlos Mario , Sarma Pallav , Gutierrez Fernando 
Published: October 2020

Abstract
An innovative technology called Data Physics*, which combines the predictive capacity of traditional numerical simulators with the speed and flexibility of machine learning, was applied to optimize a mature waterflood in the Neuquen basin in Argentina.
A reservoir model was built by combining machine learning techniques with the partial differential equations of fluid flow as applied in conventional reservoirs simulatiors. The approach is probabilistic in nature, thereby supporting the quantification of uncertainty. Given the complex conditions of operation and control in secondary recovery projects, the dearth of data, which was inherently noisy, it is not feasible to define a unique deterministic solution. The proposed approach provides physically possible and statistically viable distributions (ranges and frequencies) of the variables affecting reservoir behavior.
Due to its predictive capabilities, the reservoir model, created at a layer level using raw uninterpreted production and injection data, is capable of reproducing and predicting field production history. This enables continuous closed loop optimization and provides a program of injection water redistribution. The result is optimized production, and reserves development with reduced injection costs.
As part of the assessment of different prescriptions, the operator wanted to evaluate the optimum way to cycle two sets of injectors to reduce water handling and injection costs. A robust connectivity model was built from the reservoir model which was then used to evaluate and compare the different alternatives to cycle injectors during two years versus an optimum injection redistribution. The results include production forecasts for the scenarios evaluated which, when executed, would allow the customer to reduce water cost while maintaining production levels unaltered.
An Efficient Alternative for Joining Internally Clad Pipes Using Innovative Welding Techniques and Equipment

Published: October 2020

Abstract
High strength steel pipes internally clad with Ni superalloys are components widely used in the oil and gas industry, with distinguished application in the production of rigid steel risers. The joining of clad pipes is carried out through a girth welding process, in which the joint is totally filled with a filler material similar to the internal clad. However, depending on mechanical strength of the pipe substrate, an undermatching condition is created. Thus, a critical weaker region results in the welded joint, where loads and plastic deformations will occur preferentially. In view of this problematic, this work aims to apply an alternative approach as a method of joining clad steel pipes, whereby an overmatching condition is achieved in the joint. This technique is carried out through a double-sided weld, which enables the use of steel filler wire in the joint filling externally, preserving the internal cladding through an inside diameter weld with a CRA filler wire. A C-Mn API X-65 steel pipe, metallurgically cladded with Inconel 625 was used in the study. For joining the pipes, modern welding techniques as GMAW CCC (Controlled Short-Circuit) and GTAW with dynamic wire feeding were applied. The developments showcased weld beads with excellent surface appearance and without welding defects, fact verified by internal videoscopy and cross section macrography. Energy Dispersive X-ray Spectometry (EDS) indicated low iron dilutions, around 2,7% in weight, on the internal weld bead surface. The double-sided welding methodology produces favorable conditions to reach joint properties equalization, enabling the employment of steel filler wire in joint filling, in addition to preserving the internal clad and its corrosion properties.
