Une Ã©tude a Ã©tÃ© rÃ©alisÃ©e dans les RÃ©gions de la BagouÃ©, du Poro et du Tchologo pour Ã©valuer les facteurs dâ€™avant-garde du niveau sanitaire des vergers anacardiers en CÃ´te dâ€™Ivoire. Les donnÃ©es ont Ã©tÃ© recueillies dans 250 plantations sÃ©lectionnÃ©es au hasard sur des fiches de relevÃ©s sanitaires. Le niveau sanitaire de dix pieds par hectare a Ã©tÃ© Ã©valuÃ© sur la diagonale en zigzag dans chaque verger dâ€™anacardier. Les techniques dâ€™analyse utilisÃ©es comprenaient des statistiques descriptives pour les caractÃ©ristiques des arbres et un modÃ¨le de rÃ©gression linÃ©aire pour dÃ©terminer les principaux facteurs qui influencent le niveau sanitaire des vergers. Il resort de cette Ã©tude que le nombre de plantes par hectare, lâ€™Ã¢ge du verger, la source des semences, la nature du sol et lâ€™utilisation de pesticides ont eu une influence significative sur le niveau sanitaire des vergers. Les exploitations de plus de 100 arbres par hectare et le manque dâ€™entretien des vergers ont augmentÃ© lâ€™infestation de plus de 5%. Les vergers qui respectent cette densitÃ© ont rÃ©duit lâ€™incidence des agents pathogÃ¨nes Ã  moins de 25%. Les efforts dâ€™amÃ©lioration de la production de la noix dâ€™anacarde en CÃ´te dâ€™Ivoire doivent tenir compte de ces facteurs dâ€™avant-garde. Lâ€™Ã©tude a recommandÃ© une meilleure formation des producteurs sur les techniques de lutte agronomique en cajouculture pour une production saine.
A study was carried out in BagouÃ©, Poro and Tchologo Regions to assess the determinants of the cashew orchards sanitary level in Cote dâ€™Ivoire. Data were collected from 250 randomly selected plantations through the use of structured sanitary sheet. The sanitary level of ten trees per hectare was assessed on the zigzag diagonal in each cashew tree orchard. Analytical techniques employed included descriptive statistics to analyze the characteristics of respondent cashew orchards, and linear regression model to examine the determinants of orchards sanitary level among the farms visited. From this study, it appears that the number of plants per hectare, farm age, source of seeds, nature of soil and the use of pesticides were found to significantly influence sanitary level of cashew orchards. In a priori expectation, the farms with more than 100 trees per hectare and the lack of maintenance of orchards were found to be increased the infestation more than 5%. The farms which respect this line reduced the incidence of pathogens less than 25%. Efforts to improve cashew nut production in Cote d'Ivoire must take  these leading factors into account. The study recommended better training of producers on cashew nut agronomic control techniques for healthy production.

Tackling Slippage
Authors: Hickling Sophie
Published: November 2020

This issue of Frontiers of CLTS explores current thinking and practice on the topic of tackling slippage of open defecation free (ODF) status. It looks at how slippage is defined and identified, and at different patterns of slippage that are seen after ODF is declared. Although a considerable amount has been written on how to establish strong Community-Led Total sanitation (CLTS) programmes that prevent slippage from happening, this issue looks at how to reverse slippage that has already taken place. Note however, that at a certain level, strategies used to reverse slippage and those used in advance to set a programme up for success to prevent slippage occurring overlap. From the literature, there is little documented evidence on how slippage can be reversed; evidence and guidance tend to focus on prevention. This review begins to address this gap. Implementers are encouraged to use the proposed patterns of slippage framework and slippage factors section to understand the type and extent of slippage experienced, then use the examples in the section on tackling slippage to identify potential slippage responses. In addition to a review of current literature,1 in depth interviews were carried out with key informants at global, regional and country level. Key informants were selected purposively to identify experiences and innovations in tackling slippage from across the sector.

The Meauco Formation, a dune region of the central Pampa province, has numerous shallow lakes. Although there is hydrological information about them, it is very scarce about their limnological characteristics. The objectives are to know the physical-chemical and zooplankton parameters of two nearby shallow lakes, with and without fishes: Santa Isabel I (SI I) and Santa Isabel II (I II) respectively, and determine the influence of zooplankton on phytoplankton biomass and transparency. It was sampled during 2018 and 2019. In both the mean salinity were less than 1g.L-1 and the Secchi disk depth was around 0.45m. The chlorophyll concentrations varied between 9.32 and 11.63 mg.m-3. Seven cladocerans, 4 copepods and 20 rotifers were recorded. Most of the taxa were shared by both lakes, however, 20 rotifers were recorded in SI I and 13 in SI II. The total zooplankton density did not differ, but SI I had greater abundance of rotifers (69% of total) and SI II of crustaceans (72%). The presence of fish influences the zooplankton composition but its small size, even in the absence of fish, makes it have little influence on the phytoplankton; therefore, no differences were found in the transparency and phytoplankton biomass of both lakes.

A new species of Terminalia, T. santisukiana (Combretaceae) from fresh water swamp forest in North-Eastern Thailand is described and illustrated. The new species is similar to Terminalia nigrovenulosa, having similar leaves with glands on the leaf margin near the base and paniculate inflorescences, but it is mainly distinguished by the loose panicles with dense indumentum on the flowers and the 4–5-winged fruits. It is also similar to Terminalia polyantha, having 4–5-winged fruits, but differs by the dense indumentum on the flowers and asymmetrical fruits.
The Role of Divalent Transition Metal Ions in the Binding of Fur Dimer to DNA: Binding of Mn2+ and Co2+ to EC Fur dimer-DNA Complex
Authors: Hamed Mazen
Published: November 2020

Ferric uptake regulation protein is a repressor protein which binds an AT rich region of DNA (the iron box). Fur binds as a dimer in a helix turn helix mode and it is activated by iron(II) and other transition metal ions at elevated concentrations. Each transition metal ion induces certain conformational changes to aid the Fur binding, both the N-terminal and C-terminal domains take part in binding to DNA in addition to His 88 and His 86. The process is discussed in view of experimental reports. Fe(II), Mn(II) and Co(II) activate Fur to bind DNA but Zinc plays a structural role and does not activate Fur to bind DNA.
Autoimmune Concept Of Schizophrenia: HIistorical Roots and Current Facets
Authors: Mayorova Margarita , Butoma Boris , Churilov Leonid , Gilburd Boris , Petrova Natalia , Shoenfeld Yehuda
Published: November 2020

The review analyzes a possible role of autoimmune processes in the pathogenesis of schizophrenia and evolution of concepts on this issue from its origin to present. Risks of autoimmune processes causing schizophrenia are associated with several factors: an impaired functioning of dopaminergic and glutamatergic systems in the brain, kynurenine pathway disorder with overproduction of quinolinic, anthranilic and kynurenic acids (possibly altering both neurons and T-regulators), increased intestinal permeability, as well as food antigens’ effects, stress and infections with various pathogens at different stages of ontogenesis. An increase in the levels of proinflammatory cytokines and chemokines as well as a decrease in the levels of anti-inflammatory ones also may contribute to schizophrenia risks. Schizophrenia often occurs in those patients having various autoimmune diseases and their first-degree relatives. Cases of schizophrenia resulted from autoimmune pathogenesis (including autoimmune encephalitis caused by autoantibodies against various neuronal antigens) are characterized by quite severe cognitive and psychotic symptoms and less favorable prognosis. This severe course may result from the chronic immune damage of the neuronal receptors such as NMDA, GABA, and others and depend on hyperprolactinemia, induced by antipsychotics, but aggravating autoimmune processes [with 2 tables, 4 figures, bibliography: 99 references].

Published: November 2020

With the increased scientific interest in green technologies, many researches have been focused on the production of polymeric composites containing naturally occurring reinforcing particles. Apart from increasing mechanical properties, these additions can have a wide range of interesting effects, such as increasing the resistance to bacterial and fungal colonization. In this work, different amounts of two different natural products, namely neem and turmeric, have been added to polyethylene to act as a natural antibacterial and antifungal product for food packaging applications. Microscopic and spectroscopic characterization showed that fractions up to 5% of these products can be dispersed into low-molecular weight polyethylene, while higher amounts could not be properly dispersed and resulted in an inhomogeneous, fragile composite. In vitro testing conducted with Escherichia coli, Staphylococcus aureus and Candida albicans showed a reduced proliferation of pathogens when compared to the polyethylene references. In particular, turmeric, resulted to be more effective against E. coli when compared to neem, while they had similar performances against S. aureus. Against C. albicans, only neem was able to show a good antifungal behavior, at high concentrations. Tensile testing showed that the addition of reinforcing particles reduces the mechanical properties of polyethylene, and, in the case of turmeric, it is further reduced by UV irradiation.
DKPRG or How to Succeed in the Kolkata Paise Restaurant Game via TSP
Authors: Kastampolidou Kalliopi , Papalitsas Christos , Andronikos Theodore
Published: November 2020

The Kolkata Paise Restaurant Problem is a very challenging game, where n agents have to decide where they will have lunch on a busy day during their lunch break. The game is very interesting because there are exactly n restaurants and each restaurant can accommodate only one agent. If two or more agents happen to choose the same restaurants, only one gets served and the others have to return back to work hungry. In this paper, we tackle this problem from an entirely new angle. We abolish certain implicit assumptions, which allows us to propose a novel strategy with greater utilization of the restaurants and overall efficiency. We emphasize the spatially distributed nature of our approach, which, for the first time, perceives the locations of the restaurants as uniformly distributed in the entire city area. This critical change in perspective has profound ramifications in the topological layout of the restaurants, which now makes it completely realistic to assume that every agent has a second chance. Every agent now may visit, in case of failure, more than one restaurants, within the predefined time constraints. From the point of view of each agent, the situation now resembles more that of the iconic travelling salesman, who must compute an optimal route through n cities. Following this shift in paradigm, we advocate the use of metaheuristics, as exacts solution of the TSP are prohibitively expensive, because they can produce near-optimal solutions in a very short amount of time. The use of metaheuristics enables each agent to compute her own personalized solution, incorporating her preferences, and providing alternative destinations in case of successive failures. We analyze rigorously the resulting situation, proving probabilistic formulas that confirm the advantages of this policy and the increase in utilization. The detailed mathematical analysis of our scheme demonstrates that it can achieve utilization ranging from .85 to 0.95 from the first day, while rapidly attaining steady state utilization 1.0. Moreover, the equations we have developed generalize previously presented formulas in the literature, which can be shown to be special cases of our results.
Review of Neural Networks in the EEG Signal Recognition
Authors: Rakhmatulin Ildar
Published: November 2020

In the last decade, unprecedented progress in the development of neural networks influenced dozens of different industries, among which are signal processing for the electroencephalography process (EEG). Electroencephalography, even though it appeared in the first half of the 20th century, to this day didn’t change the physical principles of operation. But the signal processing technique due to the use of neural networks progressed significantly in this area. Evidence for this can serve that for the past 5 years more than 1000 publications on the topic of using machine learning have been published in popular libraries. Many different models of neural networks complicate the process of understanding the real situation in this area. In this manuscript, we provided the most comprehensive overview of research where were used neural networks for EEG signal processing.
The Energy, Economic and Environmental Efficiency of a PV Installation Cooperating with a Heat Pumpin the Central Part of Europe. Case study
Authors: Wciślik Sylwia , Kotrys-Działak Dagmara
Published: November 2020

The paper addresses an analysis of the efficiency and profitability of the operation of a photovoltaic installation located in the geometric centre of Europe (near Białystok, Poland), where the intensity of solar irradiation is not too high compared to other European countries. It is calculated that in that place average solar irradiation being lower even by approx. 26 kWh than that for the whole Europe, which results in a 26% drop in the economic potential of the utilisation of solar energy for its conversion. A case study and an economic analysis show that without minimum funding amounting to 50% of the investment costs paid for the modernisation of a central heating system assisted by PV cells, the time of return of pecuniary expenditures exceeds 7 years. Apart from the Simple Pay-Back Time SPBT, discount indicators determined in the paper also include the net present value NPV and the internal rate of return IRR. Moreover, a direct ecological effect has been determined for such an investment.
Silicon Nanowire Field-Effect Transistor as Next Generation Biochip for Post-Translational Modification
Authors: Su Ping-Chia , Chen Bo-Han , Lee Yi-Chan , Yang Yuh-Shyong
Published: November 2020

Protein tyrosine sulfation (PTS), a vital post-translational modification, facilitates protein–protein interactions and regulates many physiological and pathological responses. Monitoring PTS has been difficult owing to the instability of sulfated proteins and the lack of a suitable method for detecting the protein sulfate ester. In this study, we combined an in situ PTS system with an ultra-high-sensitivity polysilicon nanowire field-effect transistor (pSNWFET)-based sensor to directly monitor PTS formation. A peptide containing the tyrosine sulfation site of P-selectin glycoprotein ligand (PSGL)-1 was immobilized onto the surface of the pSNWFET by using 3-aminopropyltriethoxysilane and glutaraldehyde as linker molecules. A coupled enzyme sulfation system consisting of tyrosylprotein sulfotransferase and phenol sulfotransferase was used to catalyze PTS of the immobilized PSGL-1 peptide. Enzyme-catalyzed sulfation of the immobilized peptide was readily observed through the shift of the drain current–gate voltage curves of the pSNWFET before and after PTS. To the best of our knowledge, this is the first study to describe in situ PTS and its direct observation by using semiconductor devices. We expect that this approach can be developed as a next generation biochip for biomedical research and industries.
Estimating Lower Limb Kinematics using a Lie Group Constrained Extended Kalman Filter with a Reduced Wearable IMU Count and Distance Measurements
Authors: Sy Luke Wicent F. , Lovell Nigel H. , Redmond Stephen J.
Published: November 2020

Tracking the kinematics of human movement usually requires the use of equipment that constrains the user within a room (e.g., optical motion capture systems), or requires the use of a conspicuous body-worn measurement system (e.g., inertial measurement units (IMUs) attached to each body segment). This paper presents a novel Lie group constrained extended Kalman filter to estimate lower limb kinematics using IMU and inter-IMU distance measurements in a reduced sensor count configuration. The algorithm iterates through the prediction (kinematic equations), measurement (pelvis height assumption/inter-IMU distance measurements, zero velocity update for feet/ankles, flat-floor assumption for feet/ankles, and covariance limiter), and constraint update (formulation of hinged knee joints and ball-and-socket hip joints). The knee and hip joint angle root-mean-square errors in the sagittal plane for straight walking were 7.6±2.6∘ and 6.6±2.7∘, respectively, while the correlation coefficients were 0.95±0.03 and 0.87±0.16, respectively. Furthermore, experiments using simulated inter-IMU distance measurements show that performance improved substantially for dynamic movements, even at large noise levels (σ=0.2 m). However, further validation is recommended with actual distance measurement sensors, such as ultra-wideband ranging sensors.

Eysenhardtia platycarpa (Fabaceae) is a medicinal plant used in México and it lacks biotechnological studies for its use. The aim of this work was to establish a cell suspension cultures (CSC) of E. platycarpa, determine the phytochemical profile, and evaluate its antifungal activity. Friable callus and CSC were established with 2 mg/L 1-naphthaleneacetic acid plus 0.1 mg/L kinetin. The highest total phenolics of CSC was 15.6 mg GAE/g dry weight and the total flavonoids content ranged from 56.2 to 104.1 µg QE/g dry weight. CG‒MS analysis showed that the dichloromethane extracts of CSC, sapwood and heartwood have a high amount of hexadecanoic acid (22.3 ‒ 35.3 %) and steroids (13.5 ‒ 14.7%). Heartwood and sapwood defatted hexane extracts have the highest amount of stigmasterol (≈ 23.4%) and β-sitosterol (≈ 43%), and leaf extracts presented β-amyrin (16.3%). Methanolic leaves extracts showed mostly sugars and some polyols, mainly D-pinitol (74.3%). Dichloromethane and fatty hexane extracts of CSC exhibited the percentages inhibition higher for Sclerotium cepivorum with 71.5 and 62.0%, respectively. The maximum inhibition for Rhizoctonia solani was with fatty hexane extracts of the sapwood (51.4%). Our study suggest that CSC extracts could be used as a possible complementary alternative to synthetic fungicides.

Published: November 2020

(1) Background: Chronic musculoskeletal pain (CMP) in adolescents can negatively affect physical, psychological and social functioning, resulting in functional disability. This study aims to evaluate the effectiveness of an outpatient rehabilitation program based on graded exposure in vivo (EP) compared with care as usual (CAU) in a RCT. The aim of the interventions (EP and CAU) is to improve functional ability in adolescents with CMP, CAU is interdisciplinary outpatient rehabilitation care, based on graded activity. (2) Methods: A pragmatic multicenter randomized clinical trial with a 12-month follow-up was used. Adolescents (12-21 years) with musculoskeletal pain were invited to participate. Primary outcome was functional disability (Functional Disability Inventory). Most important secondary measures: perceived harmfulness, pain catastrophizing and intensity. Data analysis was performed by intention-to-treat linear mixed model analysis. (3) Results: Sixty adolescents were randomized to EP or CAU and data of 53 adolescents (93% female) could be analyzed (25 EP, 28 CAU). Mean age was 16.0 years (SD=1.87). Adolescents in EP showed a clinically relevant and statistically significant decrease in functional disability (estimated mean difference at least -8.81,p-values≤0.01) compared with CAU at all time points. Significant differences in favor of EP were found for perceived harmfulness at all time points (p-values≤0.002), for pain catastrophizing (PCS) at 2 months follow-up (p-value=0.039) and for pain intensity at 4 and 10 months follow-up (p-values≤0.028). (4) Conclusion: The effectiveness of the trial is in favor of the EP and leads to a significant and clinically relevant decrease in functional disability compared to usual care.
Experimental Supersymmetry
Authors: Amoroso Richard L
Published: November 2020

A radical, albeit pragmatic protocol for experimental access to putative String/M-theoretic, Einstein Unified Field Mechanical (UFM) additional dimensionality (XD) of the brane-bouquet bulk is presented. If successful, results demonstrate the existence dimensionality beyond the metric of observed physical reality provided by the Standard Model (SM) of particle physics and Cosmology. Quantum Mechanics (QM), as well-known is incomplete and further, should no longer be considered the basement of reality; meaning, Locality and Unitarity – the fundaments of quantum theory are an insufficient basis for extending the representation of reality. A seminal model of Tight Bound States (TBS) below the lowest Bohr orbit in the hydrogen atom, proposed by Vigier, is extended to a Kaluza-Klein-like (KK) cyclical tier of XD hyperspherical cavities defined within a manifold of uncertainty (MOU) of finite radius up to the semi-quantum limit, predicting, within its domain, new spectral lines in Hydrogen. The proposed protocol for this process, with phase modifications, provides efficacy of large-scale additional dimensionality (LSXD) of the brane bulk; XD-LSXD incursion duality accesses nonlocal Einsteinian UFM phenomena, leading to myriad new classes of technological innovation.

Numerous studies have warned the urgent necessity for educational institutions to organize a systematic, planned and intentional program so that coexistence in school becomes a valuable asset. Furthermore, both studies and legislation on education emphasize the need for schools to carry out specific actions to counter and prevent violence manifestations, including bullying. This paper presents partial data of the establishment of a Support System between Equals model called Help Teams in Brazilian and Spanish schools. The sample consisted of 1,191 students from secondary schools in different cities of São Paulo State and several schools in Spain. The instrument used for data collection was INSEBULL, a specific questionnaire for the diagnosis of typical bullying situations. The results show that youth protagonist is one of the possible solutions to overcome bullying in the school environment.
The absence of literature in the National Curricular Common Base for high school
Authors: Fontes Nathalia Soares , Santos Fabiano Antonio
Published: November 2020

Is there a place for teaching literature on the National Common Curriculum Base for High School? Is its presence important to the formation of humanization in individuals? The paper answers that, although it plays a founding role in the process of appropriation of the humanities, the teaching of literature is absent in the new document proposed by the Brazilian Ministry of Education. The starting point is the exacerbated pragmatism and spontaneity that pushes away school content to the detriment of an immediate teaching based on the development of skills and abilities as responses to the problems generated in this society. The analysis is made from a literary education perspective that enables the aesthetic enjoyment and the process of human objectification. It is argued that literature, as classical knowledge, should be in schools and, above all, converge with its learning objectives, which enable the construction of humanization and lead the individual to aesthetic catharsis. To this end, a documental analysis is carried out, establishing relationships between the theory of Marxist aesthetics and the approach to literature in the new regulatory document, highlighting points considered relevant for the formation of an emancipatory education.

Published: November 2020

With the growing applications of information technologies, consumer electronics products are being widely used in our daily life and at our workplaces. However, most consumer electronics packaging is one-time consumption and produces tremendous environmental impacts. Different package designs affect not only logistics efficiency, but also environmental performance. Here, various package designs for a consumer electronics product are studied and a packaging evaluation method is proposed. The method evaluates package designs mainly based on package characteristics information to avoid the inclusion of too much subjective human judgment. The criteria of the evaluation consider five aspects: marketing, logistics, cost, user convenience, and environment, including protection and containment, stackability, volume, and weight efficiency, product information, packaging cost, packaging waste, etc. The case of computer mice is used to illustrate the proposed method. The preliminary results show that different package designs of a consumer electronics product have a significant impact on logistical, marketing, economic, and environmental performance.

An advantage of solar-powered houses is the concurrent generation and consumption of power. However, the simultaneous power consumption of a solar-powered house tends to be lower than its actual load consumption. We aim to design a multi-agent system for exchanging the power value information within a solar-powered house and neighborhood in order to maximize simultaneous solar-derived power usage. This study purposes a priority order to determine the simultaneous solar-derived power usage procedure. Using the measurement data of a next-generation solar-powered house on a sunny day, we evaluate the estimation result of the domestic power balance and analyze the time series of each of the power variabilities. From the result, the three types of power usage are classified, and the four phases of the power capacity allocation are defined. We clarify the specific calculation procedure and indicate the availability of simultaneous solar-derived power usage by finding the optimum combination of the power capacity and the usage volume per hour. Finally, we estimate that the total value of available simultaneous solar-derived power usage is approximately 80% of the capacity in the solar-powered house and four hypothetical neighborhood houses, contributing to a drastic reduction in surplus power.

Recently, cubic boron nitride (CBN) cutting tools and high pressure coolant (HPC) have garnered significant attention for high performance machining of difficult-to-cut materials, such as nickel-based super alloy, Inconel 718. In this study, the cutting performance of a low-CBN-content (L-CBN) cutting tool, which is known as a suitable CBN material structure for the high-speed machining of Inconel 718, is investigated under the HPC conditions. The experimetntal results show that, although crater wear is significantly suppressed as the coolant pressure increases, the combination of high cutting speed and high pressure coolant causes severe thermal cracking on the tool rake face of the L-CBN cutting tool. Hence, we evaluate the cutting performance of high-CBN-content (H-CBN) cutting tool which has smaller coefficcient of thermal expansion, compared with the L-CBN cutting tool. A series of cutting experiments shows that changing the material structure of the CBN tool effectively suppressed thermal cracking and that the H-CBN tool is a highly promising option for the high performance machining of Inconel 718.

The study examined the influence of anonymity and mutual disclosure on trust in online counselling relationships in Obafemi Awolowo University (OAU), Ile-Ife, Nigeria. The study adopted a descriptive survey research design. The population for the study comprised undergraduate and postgraduate students of Obafemi Awolowo University (OAU), Ile-Ife, Nigeria.  Findings revealed that majority of the students showed moderate level of trust. It was also revealed that anonymity (β = 0.310, p < 0.05) and mutual disclosure (β= 0.627, p < 0.05) had positive and significant influence on counsellor-client trust. Also, sex significantly and inversely influenced counsellor-client trust (β= -1.683, p < 0.05), while the type of concerns presented by students had no significant relationship with counsellor-client trust (F= 2.313, p > 0.05).

Published: November 2020

In this paper, comprehensive experimental and simulation studies were conducted to determine the optimum combination of seat and ball for actual gas lift valve (GLV). The experiments were run for multiple ball and seat sizes to cover the whole gamut of industrially used GLVs. A numerical model, built based on computational fluid dynamics (CFD), was validated first using experimental results. The difference between experimental and simulation runs for multiple cases was found to be maximum 5%. Finally, results from both simulations and experiments were utilized to determine the optimum seat and ball geometries.

From the actual GLV experiments and the simulations, it was concluded that the optimum port top diameter (PTD) of the seat is 2/16-inch larger than the port bottom diameter (PBD) when used in combination with a ball that is 1/16-inch larger in dimeter than the PBD. It was also concluded that, with the aforementioned optimum combination of the ball and the seat, the entirely beveled seats perform better than both the partially beveled seats and the sharp edge seats. This optimum combination of the ball and the seat resulted in a GLV gas throughput improvement of more than 27% over the currently used design in the industry for 5/16-inch port seat. For larger port seats, this improvement is expected to be even greater.
Full-Scale Validation Test of Liquid Assisted Gas Lift LAGL

A new and transformational gas lift method termed Liquid Assisted Gas Lift (LAGL) has been developed. LAGL utilizes the co-injection of liquid with lift gas to reduce surface pressure requirements for the kick-off of gas lift, simplify well completions and improve system reliability/flexibility. PetroleumETC executed a Shell GameChanger project to demonstrate the delivery of LAGL for well unloading and kick-off of gas lift. Qualification testing was performed at a university test facility utilizing a 2,788 ft TVD test well with 5 ½-inch casing and 2 7/8-inch tubing. Air and water were the test media. In-well measurements were available bottomhole and mid-string for both the annulus and the tubing. The test well was successfully unloaded in 2 hours with a maximum pressure of 535 psig using manual operation of the module. Two automated tests were successfully conducted; one requiring 2 hours (670 psig max pressure) and one requiring 1 hr and 24 min (724 max pressure). Many lessons were learned, effectively de-risking the technology for field application. A new sliding-sleeve orifice valve was also tested with water, air and under multiphase flow conditions. The larger orifice sizes provided by the 2 7/8-inch sliding sleeve slim valve provides for faster unloading using the LAGL process. The paper provides an update on advances in the value case for the new LAGL technology. LAGL utilizes a single G-L valve, which reduces system costs versus the traditional use of multiple G-L valves and mandrels and dramatically reduces the risk of multi-pointing. LAGL provides the advantage of High-Pressure Single Point Gas Lift (HPSPGL) without the need for high pressures on the well pad, changing surface piping and a high pressure compressor.

Published: November 2020

Unconventional oil and gas development revolutionized the energy sector in North America and has been transforming the world's energy markets. Notwithstanding the enormous potential, unconventional resource development presents unique challenges to production and long-term hydrocarbon recoveries. As market dynamics are shifting, technologies are advancing, opening up new opportunities in areas once considered out of reach. This paper describes a new technology, a subsurface compressor system, which simultaneously removes liquids, increases gas production, and improves recoverable reserves in gas wells. The subsurface compressor can reverse the vicious cycle of liquid loading, which decreases gas production from a gas well and leads to premature abandonment, by creating a virtuous cycle of increased gas and condensate production. The complete process from well analysis, performance projection, deployment, commissioning to operation are discussed. A recently completed the world's very first field trial in an unconventional shale gas well supports the mechanism of subsurface gas compression and its impacts and benefits on unconventional gas production.
