Authors: Wu Gang , Ruben Marc D. , Lee Yinyeng , Li Jiajia , Hughes Michael E. , Hogenesch John B.
Published: November 2020

Transcriptome profiling at different times of day is powerful for studying circadian regulation in model organisms and humans. To date, 24 h profiles from many tissue types suggest that about half of all genes are circadian-expressed somewhere in the body. However, few of these studies focused on the brain. Thus, despite known links between circadian disruption and neurological disease, we have virtually no mechanistic understanding. In the coming decade, we expect more genome-wide studies of time of day in different brain diseases, regions, and cell types. We expect just as many different approaches to the design and analysis of these studies. This review considers key principles of circadian tran scriptomics, with the goal of maximizing utility and reproducibility of future studies in the nervous system.
The effect of fatigue on brain connectivity networks
Authors: Zhang Shangen , Sun Jingnan , Gao Xiaorong
Published: November 2020

In the fatigue state, the neural response characteristics of the brain might be different from those in the normal state. Brain functional connectivity analysis is an effective tool for distinguishing between different brain states. For example, comparative studies on the brain functional connectivity have the potential to reveal the functional differences in different mental states. The purpose of this study was to explore the relationship between human mental states and brain control abilities by analyzing the effect of fatigue on the brain response connectivity. In particular, the phase‐scrambling method was used to generate images with two noise levels, while the N‐back working memory task was used to induce the fatigue state in subjects. The paradigm of rapid serial visual presentation (RSVP) was used to present visual stimuli. The analysis of brain connections in the normal and fatigue states was conducted using the open‐source eConnectome toolbox. The results demonstrated that the control areas of neural responses were mainly distributed in the parietal region in both the normal and fatigue states. Compared to the normal state, the brain connectivity power in the parietal region was significantly weakened under the fatigue state, which indicates that the control ability of the brain is reduced in the fatigue state.

Published: November 2020

Various living creatures exhibit embodiment intelligence, which is reflected by a collaborative interaction of the brain, body, and environment. The actual behavior of embodiment intelligence is generated by a continuous and dynamic interaction between a subject and the environment through information perception and physical manipulation. The physical interaction between a robot and the environment is the basis for realizing embodied perception and learning. Tactile information plays a critical role in this physical interaction process. It can be used to ensure safety, stability, and compliance, and can provide unique information that is difficult to capture using other perception modalities. However, due to the limitations of existing sensors and perception and learning methods, the development of robotic tactile research lags significantly behind other sensing modalities, such as vision and hearing, thereby seriously restricting the development of robotic embodiment intelligence. This paper presents the current challenges related to robotic tactile embodiment intelligence and reviews the theory and methods of robotic embodied tactile intelligence. Tactile perception and learning methods for embodiment intelligence can be designed based on the development of new large‐scale tactile array sensing devices, with the aim to make breakthroughs in the neuromorphic computing technology of tactile intelligence.

Within the qualitative approach, a multiple case study was used as a research design. A sample size of six participants (N=6, two males and four females) was drawn from a rural school in a Thabo Mofutsanyana District in the Free State Province. Purposive and convenience sampling techniques were used to select participants in this study. The participants had teaching experience ranging from 2 to 7 years. Data were collected through telephone interviews and analysed using thematic analysis. The finding suggested that the Protection Motivation Theory was an insightful framework in responding to the challenges emanating from COVID-19 induced online teaching and learning. Thus, the study revealed that there are various challenges to online learning. These include poor parental involvement in children’s homework, incomplete work and poor performance, insufficient personal protective equipment, poor access to network access, and lack of learning devices. Subsequently, we recommend that stakeholders such as the Department of Education, Department of Basic Education, and School Governing Bodies, among others, should ensure that parents are sensitized about the need for learners to manage the resources at their disposal. Furthermore, the provision of adequate resources such as; Internet connectivity and Information and Communication Technologies learning devices is imperative.

Integrated Tubulars Supply Model Provides Cost Savings to Drilling Projects
Authors: Hamzah M.
Published: November 2020

Classical Oil Country Tubular Goods (OCTG) procurement approach has been practiced in the indus-try with the typical process of setting a quantity level of tubulars ahead of the drilling project, includ-ing contingencies, and delivery to a storage location close to the drilling site. The total cost of owner-ship for a drilling campaign can be reduced in the range of 10-30% related to tubulars across the en-tire supply chain. In recent decades, the strategy of OCTG supply has seen an improvement resulting in significant cost savings by employing the integrated tubular supply chain management. Such method integrates the demand and supply planning of OCTG of several wells in a drilling project and synergize the infor-mation between the pipes manufacturer and drilling operators to optimize the deliveries, minimizing inventory levels and safety stocks. While the capital cost of carrying the inventory of OCTG can be reduced by avoiding the procurement of substantial volume upfront for the entire project, several hidden costs by carrying this inventory can also be minimized. These include storage costs, maintenance costs, and costs associated to stock obsolescence. Digital technologies also simplify the tasks related to the traceability of the tubulars since the release of the pipes from the manufacturing facility to the rig floor. Health, Safety, and Environmental (HSE) risks associated to pipe movements on the rig can be minimized. Pipe-by-pipe traceability provides pipes’ history and their properties on demand. Digitalization of the process has proven to simplify back end administrative tasks. The paper reviews the OCTG supply methods and lays out tangible improvement factors by employ-ing an alternative scheme as discussed in the paper. It also provides an insight on potential cost savings based on the observed and calculated experiences from several operations in the Asia Pacific region.
Unlocking hydrocarbon reserves by Optimizing Pore pressure and Fracture Pressure Predictions in Mature Mahakam Delta Fields
Authors: Pramono W.
Published: November 2020

The Mahakam PSC is a mature oil and gas concession in the Mahakam Delta which has been producing for more than 40 years. More than 100 wells per year are drilled from deltaic to offshore production fields (Tunu, Tambora, Handil, Peciko, Bekapai, Sisi-Nubi, and South Mahakam). A total cumulative production of 19 TCF of gas and approximately 1.5 Billion barrels of oil have been produced since 1974. The Peak of Mahakam PSC production started from 2005 and the PSC has been facing natural decline from 2010 to the current date. Several strategies have been implemented to maintain the production rate, and one of them is unlocking less developed reservoirs in the deeper target. Overpressure is one of the challenges to reach the deeper target reservoir. Drilling in an overpressure zone often has serious and unpredictable outcomes. In addition, it has also been exacerbated by massive production in the main zone reservoirs for many years. This massive production has reduced reservoir pressure that led to the decreasing of fracture pressure. These two subsurface challenges effect the narrow window for drilling in the Mahakam operational area and it will certainly also affect the safety, cost and economics of the wells. So, optimizing pore pressure and fracture pressure predictions become the key to unlock less developed reservoirs in mature Mahakam fields. Pore Pressure and Fracture Pressure predictions are developed by understanding the geopressure concept, predicting pore pressure, estimating fracture pressure, developing 3D pore pressure model and performing reservoir distribution analysis. During 2019, eight challenging wells had been drilled and succeeded in unlocking 7.7 BCF of gas reserves. Besides that, Non Productive Time (NPT) of the well control is also decreased yearly and affects the well’s cost efficiency. The improvement of the methodology has been implemented comprehensively to support upcoming challenging exploration and is also expected to sustain the future development of mature Mahakam Fields.
Novel Approach on Thin Bed Reservoir Case Study from Muda Formation, Natuna Basin
Authors: Panjaitan J.
Published: November 2020

The presence of shale in thin beds reservoirs affects formation evaluation where the standard conventional log analyses are not designed to properly correct this effect. The conventional logging tools, with low vertical resolution, are not able to characterize these thin beds. This implies that log values do not represent the true bed or layer properties, but rather an average of multiple beds. Muda Formation are characterized by thin bed layers, made up of clastic rock sequences with dominant lithology of sandstone inter-bedded with shale, siltstone, and organic material as confirmed by drilling cuttings, logs response, and also supported by observation from sidewall cores. There are many uncertainties related to the presence of thin beds, primarily sand, silt, shale or their combination in term of their petrophysical properties and lateral extent. Inadequate reservoir characterization can cause significant amounts of oil and gas to remain unidentified. Accurate petrophysical parameters determination play an important role in the development plan of a field. The lateral and vertical variations in the petrophysical properties of the reservoir lead to different scenarios of the field development. The study of Muda Formation in this structure has integrated the sidewall core and log data. The contribution of the thin sand laminae to the average log response resulted in underestimating the porosity (Ф) and hydrocarbon saturation (Sh). The advanced measurement, like the resistivity anisotropy, proved quite useful as the vertical and horizontal resistivity across these beds leading to measurable electrical anisotropy. The resistivity measured perpendicular to the bedding is significantly higher than resistivity measured parallel to the bedding. The situation occurs due to high resistivity sand layers interbedded with low resistivity shale layers. The true sand porosity and hydrocarbon saturation were calculated using the laminated sand shale sequence and calibrated with core data. The study led to the more realistic petrophysical estimation of the sand shale laminae. A combination and integration of high-resolution image log for sand count, nuclear magnetic resonance (NMR) for porosity evaluation and triaxial resistivity for volumetric model through Laminated Sand Analysis approach are found useful to solve thin bed reservoir issue.

Published: November 2020

Three-dimensional reconstruction of real objects comprises capturing the appearance and the shape for these objects and determining the three-dimensional coordinates for their profiles. This reconstruction process can be accomplished either by using active or passive techniques. In this paper, a new fusion method is proposed for 3D reconstruction. This method exploits the advantages of both stereo-based passive and laser-based active techniques and overcomes their limitations to improve the performance of 3D reconstruction. With this method, a hybrid laser-based structured light scanning system is designed and implemented. This system captures the required information using passive and active techniques and uses the proposed fusion method for 3D reconstruction. The performance of the proposed method and its scanning system were experimentally evaluated. The evaluation results show high reconstruction performance for the proposed fusion method over the traditional 3D reconstruction techniques. The results also show the effectiveness of the hybrid laser scanning system and its ability to scan and reconstruct the shape and the appearance for real objects using the proposed fusion method.

Published: November 2020

There are a huge number of types of well operations that involve pumping various reagents into the reservoir through the well. In this case, there may be a need for destruction and removal of the reagents used, associated with non-standard or technological problems, for example, undesirable deterioration of the filtration properties of the reservoir in the bottom-hole zone, blocking the well or bottom of the well. In this case, breakers are used – reagents that destroy or change the physical and chemical properties of certain chemical products, after which they can be easily removed from the well. Temposcreen-Plus reagent is applied for water shutoff. This article presents the results of laboratory studies of the effectiveness of various breakers for the destruction of polymer-gel systems based on the Temposcreen-Plus reagent. Some aspects of methods for studying the physical and chemical properties of polymer dispersed systems are also described.

Authors: Chigarev B.N.
Published: November 2020

A brief discussion on the Clean Energy Transitions Programme is presented. The keywords of 2256 publications indexed in the Web of Science abstract database for the period 2019–2020 are analyzed. It is shown that the dominant keywords describe well the subject area under review related to renewable energy, its optimization, carbon dioxide emission, energy generation and storage, specific types of renewable energy, economic growth, innovation, efficiency, demand and sustainability. In doing so, authors are more likely to use more general terms to classify their publications, and keywords plus of the Web of Science platform are more likely to describe specific processes related to the transition to clean energy. Basing on keyword clustering, 5 sustainable sub-themes in the clean energy theme are identified. It is demonstrated that bibliometric analysis can be used to highlight emerging topics.

Thermo-mechanical stress analysis of dissimilar material joints using FEM
Authors: Somadder Somnath
Published: November 2020

Abstract: This article presents numerical investigation of isotropic dissimilar material joints. Dissimilar material joints are broadly used in in various structures, including offshore, nuclear, electronic packaging, IC chip and spacecraft various fields of science and technology. In bi-material joints two different material are bonded with common interface region. High stress concentration occur at the interface of the joint under thermo-mechanical loadings due to the difference in the elastic properties and the thermal expansion coefficients of dissimilar materials. The stresses acting along the interface of dissimilar material joints are very important to determine whether the structure is reliable or not for operation. The main purpose of this research is to provide finite element solutions to predict the stress distribution at the interface of the joint based on the theory of elasticity. Keywords: Numerical Investigation, Dissimilar material joints, Stress concentration, Stress distributions, Theory of elasticity.

Sporcular terlemeyle beraber su ve elektrolit kaybederken enerji depolarını da kullanırlar. Sıvı kaybının çok olması vücuttan atılan elektrolit miktarını arttırmakta, enerji tüketimini de hızlandırmaktadır. Yapılan araştırmalar vücut kütlesinin %2’den fazlasının sıvı kaybı olarak oluşması durumunda aerobik performansta düşüş yaşandığını ve anaerobik performansın da etkilenebileceğini göstermektedir. İçerik analizi yöntemi kullanılmış olan bu nitel araştırmanın amacı, hidrasyonun egzersiz performansına etkilerini ve sporcular için sıvı alım stratejilerini son yapılan çalışmalarla derlemektir. Sonuç olarak, performansı koruyabilmek için egzersiz öncesi, sırasında ve sonrası için uygun sıvı tüketiminin önemli olduğu, vücudun terle kaybettiği minerallerin geri kazanımının gerekliliği yapılan çalışmaların ortak noktasını oluşturmaktadır.
