Contribution of magnetic resonance imaging in the biomechanical interpretation of the temporomandibular joint. Clinical case report
Authors: Zambrano de Carrasquero Elba
Published: November 2022

X-rays and tomography, in their different modalities, are used as auxiliary diagnostic elements in temporomandibular joint (TMJ) dysfunction, both in static and dynamic situations; however, because they only allow the observation of bone structures, magnetic resonance imaging (MRI) is the ideal method to analyze, among other structures, the articular disc. Among the internal disorders of the TMJ are the abnormal postural relationships between the disc, mandibular head, fossa and articular tubercle, which can even lead to a musculoskeletal condition causing noise, pain and functional limitation. The clinical evaluation of temporomandibular dysfunctions is complex, especially in asymptomatic patients; the Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), place these entities within the AXIS I protocol, considering that the image is not strictly necessary. However, analyzing the disc situation statically and dynamically, with its surroundings, allows considering the loads that generate dysfunction, leading to the correct diagnosis, and selection of the best treatment. A clinical case is presented, an asymptomatic patient, without functional limitation, who reported a history of occasional mouth opening locking upon awakening. MRI was indicated, finding an abnormal position of the disc, in a static and dynamic situation; finding anterior displacement of the disc in the right and left TMJ in closed mouth position, dynamically anterior displacement without recapture in the right TMJ and with recapture in the left TMJ; Treatment was performed with Jaw Functional Orthopedics (JFO), obtaining changes in the dynamic disc-mandibular head relationship, anterior displacement with recapture of the right TMJ and total recapture of the left TMJ.

Published: November 2022

The current state policy of the Russian Federation supports the development of physical culture and sports, in particular hockey, to solve a complex of social and political problems. Sport as a sphere and industry is changing rapidly due to various external challenges. Consequently, strategic management has to adapt to these changes and challenges. The current situation demands a clear strategic plan, not universal business models or outdated strategic methods. Sport is a business that requires complex management and a strategy. A sports team owes its success not only to its athletes but also to the proper strategic decisions. Unfortunately, the methodology of developing strategies for sports industry received little scientific attention. The present research objective was to identify effective strategies in the sports industry. This paper clarifies and systematizes many concepts and approaches to the strategy development that have been adapted for sports organizations with all their specifics. The authors propose a new scheme for sports industry strategy and a number of recommendations on the strategy development in the sports industry that can be recommended for practical application. The study relied on the general theory and methodology of strategizing developed by V.L. Kvint, Foreign Member of the Russian Academy of Sciences, Dr.Sc.(Econ.), at the Center for Strategic Studies of the Institute for Mathematical Research of Complex Systems, the Central Economics and Mathematics Institute of the Russian Academy of Sciences, the Department of Economic and Financial Strategy of the Moscow School of Economics of the Lomonosov Moscow State University, the Department of Regional and Sectoral Development Strategy of the Kemerovo State University, and the Department of Industrial Strategy of National University of Science and Technology “MISIS”.

Authors: Edamo Muluneh Legesse , Bushira Kedir , Ukumo Tigistu Yisihak
Published: November 2022

Flood susceptibility mapping plays a key role in planning flood mitigation. Floods may not be avoidable due to the future climate changes. The Bilate catchment in Ethiopia is vulnerable to flood disasters and it is used as case study in this project. The analytical hierarchy process (AHP) under multi-criteria decision analysis (MCDA) is used to develop the flood susceptibility map of the Bilate catchment. It was accordingly found that factors such as slope, rainfall, land use/land cover (LULC), elevation, topographic wetness index (TWI), soil type (ST), sediment transport index (STI), drainage density (DD), stream power index (SPI), and distance from the river (DR) have significant effects on the flood intensity in Bilate catchment. Each factor was evaluated by AHP, and an output map was developed in ARCGIS. The prepared flood susceptibility map was classified into five classes such as very low, low, moderate, high, and very high 9.3%, 32.6%, 41.2%, 10.8%, and 6.1% areas respectively. The flood susceptibility map reported in this research is a great resource for relevant parties, including government and non-governmental organizations, to evaluate the impacts of flooding in the Bilate catchment and throughout the nation. The flood identified in this research may also be used as a reference to flood-related studies.
Applicability of several machine learning models in estimation of vortex tube trapping efficiency
Authors: Kumar Shubham , Tiwari N. K. , Ranjan Subodh
Published: November 2022

A vortex tube ejector comprises a tube with a slitted crown that lies flush across the entire width of a channel bed surface. The bed and suspended loads are ejected with minimal flushing water through the slit with the same efficacy as any other alternative extractor. The whirling flow phenomena through the vortex duct are very complex, so ordinary classical models have results contrary to required design guidelines. So, the machine learning (ML) models of the artificial neural network (ANN), deep neural network (DNN), gradient boosting machine (GBM), stacked ensemble (SE), and adaptive neuro-fuzzy inference system (ANFIS) are used to predict vortex tube trapping efficiency (VTE). The input dataset takes the size of the sediment (Sz), concentration (I) of the sediment, the ratio of slit thickness to diameter of the tube (th/dia), and extraction ratio (Extro) while trapping efficiency (TE) is taken as output. Based on statistical assessments, GBM appears to be better than all proposed models. However, other proposed ML models give comparable performance. The classical models, multivariate linear, and nonlinear regression techniques also provide comparatively good results. According to sensitivity analyses, the extraction ratio is the most relevant parameter in evaluating the VTE.

Published: November 2022

Wetlands deliver many ecosystem services but are under continuous threat due to various anthropogenic activities. The present study has been carried out to examine the suitability of Kusheshwar-Asthan wetland's water for agriculture. A total of 57 water samples were analyzed for various water quality parameters like electrical conductivity, pH, temperature, dissolved oxygen (DO), major cations (Ca2+, Mg2+, Na+, K+), and major anions (PO43–, SO42−, N-NO3−, Cl−, HCO3−). Overall, the water of the wetland was found to be alkaline. The pre-monsoon samples had a relatively higher concentration in most of analyzed parameters except for pH, DO, NO3−, PO43− and Cl−. The concentration of cations follows the order of Na+ > Ca2+ > Mg2+ > K+ in both seasons and for anions it is HCO3− > SO42− > Cl− > NO3− > PO43− for pre-monsoon and HCO3− > Cl− > SO42− > NO3− > PO43− for post-monsoon. According to Piper diagram and Durov plot, Na-K-HCO3 was the major hydro chemical facies of the surface water. The various irrigation quality parameters showed that wetland water can be categorized as good to excellent quality. As a result, this finding can aid in the long-term sustainable use of the wetland water with regulated anthropogenic interventions. The study will be beneficial in designing long-term extensive management plans for the conservation of the wetland.

Published: November 2022

The synthesis of optimized thin film nanocomposite (TFN) membrane with no or few defects is an efficacious method which can improve nanofiltration performance. However, poor dispersion of fillers in the organic phase and wrong compatibility between fillers and polymerizate are still a serious problem. In this study, the particle size of metal organic framework (MOF), aluminum-based metal-organic frameworks (CAU-1) was modulated and for the first time, dodecyl aldehyde was used to modify the surface hydrophobicity of CAU-1, which improved the dispersibility and inhibited the aggregation in the trimesoyl chloride (TMC)/n-hexane solution; later CAU-1 and modified CAU-1 were incorporated into the polyamide (PA) selective layer to synthesize TFN membrane by interfacial polymerization (IP). The particle size modulation and modification of the CAU-1 were demonstrated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) characterization. The characterization showed that PA selective layer was synthesized on the top layer of polysulfone (PSF) substrate. The pure water flux of the TFN membrane was increased to 79.89 ± 1.24 L·m−2·h−1·bar−1 compared to the original thin film composite (TFC) membrane, which was due to the polymerization of 100 nm modified CAU-1 on the PA layer to form a new water molecular channel, thus increasing the water flux by about 70%.

Authors: Tovío-Martínez Eilien , Urbano-del Valle Samuel , Cantillo-Pallares Oswaldo
Published: November 2022

Included dental organs are associated with various jaws pathologies, among the most frequent are cysts, which are benign lesions that develop around the crowns from permanent teeth. The aim of this research is to propose a therapeutic algorithm and a treatment plan combined with two known techniques, in addition to describe clinical and radiographic findings and conservative therapeutic management. For this, gender and clinical diagnosis data were obtained from a series of 3 cases of dentigerous cyst, in which clinical, histological, radiographic characteristics and treatments used were described. In each case conservative surgical treatment was given accompanied by gauze soaked in nitrofurantoin. Because dentigerous cysts are the most common pathology associated with included dental organs, which can be detected in routine radiographic examinations, this must be corroborated with the histopathological study, allowing less invasive techniques, this work is based on a therapeutic algorithm and combined treatment plan, not only in children but also in adults, regardless of their size.

Published: November 2022

A chymotrypsin inhibitor 2 variant, CI2(G83D), was expressed as a fusion with fd minor coat protein, pili, via a flexible linker (Gly-Ala 3) and displayed on the surface of bacteriophage. Biopanning with immobilised subtilisin BPN' demonstrated that the inhibitor-displaying phage could be selectively enriched 13-fold over control phage in one round of affinity purification. The inhibitor (incorporating the linker sequence) was also expressed as soluble protein in E. coli and purified to homogeneity. Kinetic analysis revealed the displayed inhibitor possesses inhibition characteristics that approximate those of this soluble inhibitor. The results demonstrate that functionally active inhibitor can be displayed on the phage surface. Further use of this technology should facilitate the selection of remodelled inhibitor variants exhibiting novel protease binding specificities.

Published: November 2022

Background:

Social distancing as a preventive measure to contain the spread of the COVID-19 pandemic has resulted in many people working from home, using online digital resources. Staying at home has led to the adaptation of many work activities to allow continuity of people´s jobs. It can also affect home routines and ways of working, thereby leading to changes in behavior, as the main interest of this study.

Objective:

The study aimed to assess the impact on human behavior of working conditions in home office format due to social distancing.

Methods:

Data collection was done online, using a specific computational tool (Google Forms) for this type of research, using the Home Office Work Scale (HOWS) validated and published in Mental Health and Addiction Research in 2021, with a total sample of 1,056 valid questionnaires. After the data collection, a database was created for statistical analysis of the results.

Results:

More women than men volunteered to answer the questionnaire, although the results were similar between women and men. Home office work has impacts on human behavior and results in changes in routines and adaptations in people´s personal and professional lives.

Conclusion:

Proportionally, more women participated, and there was low participation by young and elderly people. In general, people accepted home office work and the possibility of continuing to work in this format. Changes to routines and restrictive adaptations were necessary. The limitations reported for applying the scale did not compromise the results.

Published: November 2022

Introduction:

Polycystic ovary syndrome (PCOS), an endocrine glands disorder, caused by hormonal imbalance, is featured by diverse potential effects for women; while individuals perpend to those that are affecting appearance and menstruation disorder. Our aim was to assess PCOS risk factors in working women.

Materials and Methods:

The study was carried out as a literature review work through searching databases including Scopus, PubMed, and ScienceDirect for papers published before December 2019. The databases were searched for the terms such as PCO, job stress, and risk factors of PCO. Risk factors for polycystic ovarian syndrome and occupational risk factors for working women were investigated.

Results and Discussion:

There are several reasons known for PCOS like obesity and insulin resistance along with the stressors that increase its risk. Working women tend to be exposed to several stressors and being in charge of home affairs creates a higher workload and intensified stresses. The risk of PCOS is higher in women with higher stressors at work.

Conclusions:

Working women experience many stressors and taking into account that stress is a precursor or intensifier of PCOS risk factors, working women are at a higher risk of PCOS compared with housewives.

From the bench to the bedside: the history of lupin bioactive peptides as useful ingredient for the prevention of metabolic syndrome
Authors:   University of Milan, Lammi Carmen
Published: November 2022

Proteins derived from lupin seeds are gaining attention as a source of bioactive peptides. In fact, several pieces of evidence highlight the biological activities of lupin protein hydrolysates and peptides, including hypocholesterolemic, hypoglycemic, antimicrobial, anti-inflammatory, and immunomodulatory effects. The health-promoting activities of lupin peptides have been tested in different animal models and clinical trials. Briefly, diets containing protein from L. albus or L. angustifolius significantly reduce both total cholesterol and low-density lipoprotein (LDL) cholesterol (LDL-C) levels versus control diets containing casein in a rat or hamster models of hypercholesterolemia. An uncontrolled clinical trial on L. albus and two controlled ones on L. angustifolius have confirmed the hypocholesterolemic activity in humans. In light with these evidences and with a more updated perception of the phenomenon, our study suggests that the observed health-promoting activity does not lie in the native protein, but the mixture of peptides generated from the physiological hydrolysis of proteins during digestion. Indeed, many efforts have been pursued in order to characterize the molecular mechanism through which lupin hydrolysates, obtained different hydrolytic enzymes, exert hypocholesterolemic and anti-diabetic effects in vitro and in vivo. In this context, specific peptides responsible of the biological activity exerted by the peptide mixture were also identified and fully characterized from chemical and biological point of view. Doubtless, our results highlight that lupin hydrolysates may be exploited as new ingredients for the development of dietary supplements or functional foods
New high performance starch based emulsifiers using amylose inclusion complexes

Published: November 2022

High value amylose inclusion complexes can be formed when corn starch (having 70% amylose) is gelatinized in the presence of hydrophobic ligands. As the components cool, the amylose wraps around the ligand to form an amylose inclusion complex (AIC). The properties of the AIC will be dependent on the selection of the ligand and the amount of amylose. AIC formed from fatty sodium/amine salts were found to be effective non-foaming emulsifiers. These AIC fatty acid/amine salts were produced using either steam jet cooking or microwave techniques. Various fatty acid/amine salts (C10-22) were produced and evaluated.  Colloidal suspensions were produced using the AIC at concentrations of 0.1-3% solids, and their surface and rheological properties were then characterized. The AICs successfully formed stable emulsions with corn and other oils. The emulsification properties of the AIC is dependent on pH. Superior emulsifying activity at neutral and alkaline pH were obtained for fatty acid salt AICs when compared with commercial octenyl succinic anhydride (OSA) starch. The fatty amine salt AICs were superior at neutral and acidic pH with compared to OSA starch. Emulsions formed with the AIC were stable during long-term storage as the oil droplets were resistant to coalescence. Emulsion stability increased with ligand chain length due to viscosity differences (higher molecular weight ligand AICs have greater viscosity). The AIC are effective emulsifiers produced from readily available inexpensive ingredients (some food grade) formed via association rather than chemical bonds using current inexpensive industrial techniques.

Functional foods are gaining traction as a source of peptides possessing hydrogelation properties. Analysis of peptides (n=429) in egg white protein hydrolysates resulted in the identification of six peptides: IFYCPIAIM, NIFYCPIAIM, VLVNAIVFKGL, YCPIAIMSA, MMYQIGLF, and VYSFSLASRL as prominent self-assembly candidates based on prediction of their aggregation-prone segments. The objective of this study was to characterize the hydrogel formed via self-assembly of the peptides. Of the six peptides studied, NIFYCPIAIM and MMYQIGLF showed promising self-assembly and hydrogelation properties. Thioflavin T kinetics indicated that NIFYCPIAIM possesses the strongest self-assembly property, confirmed by dynamic light scattering which indicated the largest average particle diameter was achieved after 24 hours. Rheological characterization indicated that all six peptides possessed viscoelastic pseudoplastic properties and some were able to regain some level of viscosity following the exertion of shear stress. Finally, transmission electron microscopy of the six peptides showed the development of fibrillar structures of varying morphologies after 24 hours. The remarkable difference in self-assembly and hydrogelation properties of NIFYCPIAIM, IFYCPIAIMSA and YCPIAIMSA, which share a common sequence YCPIAIM, indicate the importance of amino acid sequence in the formation and property of peptide hydrogels. Identification of the egg white-derived peptides with hydrogelation properties shows a promising future for the use of functional foods in applications of drug delivery systems and tissue engineering, in the food, pharmaceutical, cosmetics, and biomedical sectors.
3D Printing of Gelatin/Alginate Based Hydrocolloids as Delivery Systems for Food and Pharmaceutical Applications
Authors:   Iowa State University, Shi Xiaolei
Published: November 2022

3D printing technology has been applied in bioprinting to fabricate three-dimensional matrices to upload living cells, biomaterials, and active ingredients, thus protecting the encapsulated active compounds. Food-grade, protein-based hydrocolloids such as gelatin, collagen, and carrageenan have been used as bioprinting materials and thickening/gelling agents commonly used in the food industry; however, the research of this area is still in its infancy. The objective of this series of studies was to investigate the feasibility of developing a 3D printed, hydrocolloid-based delivery system for active ingredients in the areas of food and pharmaceutical applications. Hydrogels were prepared using alginate and gelatin (A/G) with total solids (w/w%) of 3%, 5%, and 7% at A/G ratios of 1/2, 1/1, and 2/1. The 3D printability was assessed by flow ramp test and frequency sweep. After 3D printing, freeze-drying was conducted to solidify and dehydrate the hydrogels. Hydrogels with formulations of 3% A/G 1/2, 5% A/G 1/1, and 7% A/G 2/1 demonstrated shear-thinning flow behavior, and viscoelasticity of storage modulus (GÊ¹) higher than loss modulus (GÊº), with a loss factor (tan= GÊº/GÊ¹) in the range of 0.50-0.60 at the frequency sweep of 15-40 rad/s. The freeze-dried matrices demonstrated significantly increased hardness and crunchiness, which indicated that the novel matrix had distinguished texture properties. In one study, Bifidobacterium lactis at 10^11 CFU/g was encapsulated within alginate/gelatin hydrogels, 3D printed into tear-drop shapes, and followed by freeze-drying. The results demonstrated that the probiotics encapsulated in the novel matrix have the potential to maintain > 10^6 CFU/g during an 8-week shelf-life test conducted at ambient temperature. This study validated that this 3D-printed, hydrogel-based matrix has the potential to be used as a convenient, shelf-stable delivery system for active ingredients.
Advanced detergent formulation design by progressing from hydrophilic/lipophilic balance (HLB) to hydrophilic-lipophilic deviation (HLD)
Authors:   University of Oklahoma, Phaodee Parichat , Sabatini David ,   University of Oklahoma, Harwell Jeffrey ,   University of Oklahoma
Published: November 2022

Laundry detergent products generally contain 10-30% surfactants as active ingredients and detergency is an essential worldwide activity that the global market is anticipated to reach over $200 billion by 2027 (Research and Market, 2021). While the hydrophilic-lipophilic balance (HLB) concept was initially utilized to design detergency formulations, it does not take into consideration important formulation variables (e.g., salinity, target soil, and temperature). Detergency formulation based on microemulsion phase behavior was then widely employed as an improved formulation design but is time-consuming. More importantly, optimal formulations (optimal salinity (S*) for ionic surfactants and phase inversion temperature for nonionic surfactants) varied widely depending on surfactant systems and the nature of the soil being cleaned. The hydrophilic-lipophilic deviation (HLD) method advances the HLB approach by incorporating formulation variables and has been extensively utilized for microemulsion formation and more recently as a unifying detergency formulation design approach. HLD-based detergency results demonstrated that surfactant formulation approaching HLD of 0 (specifically, between -3 and 0) showed significant detergency improvement for oily and waxy soils with widely varying equivalent alkane carbon numbers (EACNs). Thus, the HLD approach is recommended as a unifying approach for designing effective detergency formulations for a range of surfactant systems and soils.
Biosurfactants and biopolymers: Between interactions, orthogonality and mutual responsivity
Authors:   Laboratoire de chimie de la matière condensée de Paris, Baccile Niki , Poirier Alexandre ,   Sorbonne Université, Seyrig Chloe ,   Sorbonne Université
Published: November 2022

Polymer-surfactant systems have many applications in everyday life, but their petrochemical origin is not only controversial but soon submitted to regulatory restrictions. In a more environmentally friendly approach, but also to forecast regulations in both EU and USA, biopolymer-biosurfactant systems are an interesting alternative. There exists a large family of both biobased surfactants and polymers, which possess a huge potential, however currently limited, because both the solution behaviour of the former and their interactions are not established, yet. [1] This presentation shows the first set of work where biosurfactants (sophorolipids, glucolipids) are studied together with biopolymers (chitosan, alginate, gelatin, collagen, silk fibroin) (Figure 1). The results are astonishing, as they depend on the biosurfactant's self-assembled state, but also its charge and the charge of the biopolymer. Complex coacervates are often formed at basic pH when biosurfactants are within their micellar state and charges are opposite. [2] At acidic pH, orthogonality seems to prevail when the biosurfactant reorganizes into crystalline fibers, [3] but new phases, derived from mutual electrostatic interactions, can also appear, when the biosurfactants forms a vesicular phase. [4] These data are important to design biosurfactant-biopolymer-based nanocarriers or stimuli-responsive hydrogels.  [1] Baccile N, Seyrig C, et al.

Published: November 2022

Research shows that people are increasingly valuing quality of life, for which reducing housework is key. In laundry, one challenge is stubborn stains like permanent marker and collar/cuff darkening/yellowing. While a common solution is to apply detergent directly to such stains, this takes time, effort (scrubbing), and often does not remove satisfactorily. Although more surfactant in detergent generally produces higher detergency, Alcohol Ethoxylate changes to hexagonal phase when its concentration reaches 30%, limiting surfactant concentration. Alternatively, Methyl Ester Ethoxylate (MEE) has a bent molecular geometry, keeping it in lamellar phase when 30-70% concentrated, so we examined its potential to increase surfactant concentration.We first tested MEE's effectiveness on permanent marker stains. After applying a 30% MEE solution and leaving it for 30 minutes, detergency was 30% and the fabric did not appear clean. Yellowing or permanent marker stains are caused by polymerized sebum and resin components, so we theorized that surfactant alone could not fully emulsify them.    Hence, we switched focus to the solubility parameter (SP value). When we applied an agent with a similar SP value as the permanent marker stain together with the detergent and left it for 30 minutes, detergency increased to around 40%. Furthermore, after extending application time to 6-12 hours, the detergency of applying surfactant alone increased to 70%, but the combination of agent and extended application time increased it to 85%, achieving an overwhelmingly clean appearance. This suggests that detergency factors include effectiveness of application time and polarity transformation due to water volatilization. Therefore, we believe that extended application of MEE is a simple method to achieve thorough cleanliness, which can reduce housework.  In this report, we discuss stain dissolution after detergent application and the corresponding change of detergent state during extended application.

A a systematic understanding of pea protein composition, conformation and functionalities as impacted by extraction methods is limited. Moreover, previous works focused on investigating the effects of gelling conditions on gel properties and showed that pea protein had significantly lower gelling capacity and weaker gel texture than soy proteins. However, gelling mechanism of pea protein has not been fully understood yet. Six protein isolation methods were selected, including air-classification (AC), alkaline extraction followed by isoelectric precipitation (AI) or ultrafiltration (AU), salt solution extraction followed by dialysis (SD) or ultrafiltration (SU) and micellar precipitation (MP). The pea protein compositions were analyzed by size exclusive-HPLC. The structures of proteins were revealed by Fourier-transform infrared spectrum, intrinsic fluorescence, and surface hydrophobicity. This study found that recovery methods determine the protein composition. Those obtained by ultrafiltration and dialysis contains albumins, whereas precipitation methods specifically retained globulins. Pea proteins prepared by alkaline solution had higher 11S/7S ratio and surface hydrophobicity than those by salt solution. The protein isolates by different methods showed large variation in gelling properties. Pea protein extracted by MP, AU or SU formed gels with a compressive strength of 60-80 kPa, comparable to soy protein gels. AU, SU, MP experienced high degree of unfolding upon heating, resulting in the exposure of interaction regions. The appropriate level of 7S allowed unfolded proteins to aggregate in a more organized manner through intra-floc links. These together led to homogeneous percolating-like microstructure with greater strength. Instead, the aggregates triggered by extraction through SD method prevented protein unfolding, leading to coarse particulate structure, and weak gels. This study showed the impact of extraction methods on protein composition and structure in relation to their gelling properties. The generated knowledge will help industry target the improved pea protein gels for specific applications.

Many of the giant carbonate reservoirs are in a declining phase where Enhanced Oil Recovery (EOR) techniques are needed to maintain or improve oil production. Interfacial Tension (IFT) reduction and wettability alteration (WA) are considered as the two most important mechanisms for EOR in carbonate rocks. Gemini surfactants are surfactants with more than one head group and a tail group linked by a spacer in one molecule. The main objective of this work was to evaluate the WA performance of gemini surfactants under different reservoir conditions. Novel cationic gemini surfactants of different spacer lengths were studied. Limestone substrates were oil-aged in filtered crude oil. One set of the substrates were then immersed into gemini surfactant solutions under ambient conditions. Ambient contact angle measurements were conducted. The second set of substrates were immersed in gemini surfactant solutions under different temperature and pressure conditions to evaluate the contact angle at reservoir conditions. Results showed that the tested gemini surfactant was able to alter oil-wet carbonate samples to intermediate-wet or water-wet conditions at ambient conditions. There appears to be an optimal spacer length for this group of gemini surfactants to achieve the best WA performance. Increasing the pressure from 1600 to 4600 psi had no significant effect on the contact angle results. Increasing temperature from 50°C to 110°C, however, resulted in a lower contact angle compared to the results obtained at ambient measurements. In spontaneous imbibition experiments, the gemini surfactant achieved a significantly higher oil recovery factor than commercial surfactant under a much lower concentration, due to its advantages in WA. Compared with conventional surfactants, the tested gemini surfactant improved the oil recovery significantly at a much lower concentration, indicating the superior efficiency of the newly developed gemini surfactant in the oil-wet carbonate reservoirs.

Published: November 2022

This research analyzes competency-based management (CNM) in Brazilian electoral justice courts’ personnel management (PM). This qualitative study is based on the integrated multiple case study method using data collected from documents and interviews from six courts. It applies the thematic content analysis technique, resulting in five CBM and main PM-related practices in the courts studied. It contends that despite the norms and studies’ efforts to make CBM plausible in public organizations, its assimilation has been slow and fragmented. Thus, it evidences the need to expand research and actions in CBM evaluation programs in Public Administration that provide theoretical and practical recommendations for the strategic improvement of PM in the Judiciary System.
