“Michael Cavendish’s” 14 Airs in Tablature to the Lute (1598)
Authors: Faktorovich Anna
Published: February 2023

This article is part of A Comparative Study of Byrd Songs: Volume 17 of the British Renaissance Re-Attribution and Modernization (BRRAM) series. Volume 17 offers evidence to re-assign the authorship of the 29 texts in William Byrd’s linguistic group. Volumes 1-2 of the series present a new computational-linguistic attribution method that reassigns all of the tested 303 texts from the British Renaissance to a Workshop of only six ghostwriters: Byrd, William Percy, Josuah Sylvester, Gabriel Harvey, Richard Verstegan and Gabriel Harvey. This article is a fragment from Volume 17 that presents new evidence, beyond the quantitative linguistics, for one of the Byrd re-assignments, “Michael Cavendish’s” Airs (1598), together with a modernizing translation of a representative sample of poetry from the linguistically-tested text. Airs is a rarely commented on work that tends to appear in studies of the self-plagiarisms within it, or between it and other texts. Only a single private copy of Airs has survived; this closeting is likely to have been the result of its dedication addressing Lady Arbella, who repeatedly unsuccessfully plotted with the Cavendishes and Percys to gain the British throne, first after Elizabeth I’s reign, and then after James I’s. The dedication appears to have been a propagandistic marker of support during Arbella’s attempt in 1609 to marry Seymour to challenge James I’s claim, which ended with Arbella’s imprisonment and premature death. The Airs book is likely to have been published to encourage this effort and was probably closeted and had its title-page backdated to 1598 when the attempt failed. Additionally, a comparative study is included in the Appendix between a poem in Airs and a translation of a song it echoes from Giovanni Croce.

Introduction

Bovine papillomatosis affects animal health and represents one of the greatest economic losses in the livestock sector. New control and prevention methods to protect the livestock industry from this disease are necessary. The aim of this study was to evaluate a candidate peptide for antibody production against bovine papillomavirus (BPV).

Material and Methods

A total of 64 cattle underwent wart excision among 5,485 cattle distributed over 2 to 4 farms per state and 12 farms in total in the four Mexican states of Tabasco, Chiapas, Veracruz, and Nuevo León. The prevalence of bovine papillomatosis per farm was calculated by wart visualisation. The warts were genotyped by PCR and sequenced, then a phylogenetic tree was built using MEGA X software. A synthetic peptide was designed in the ABCpred, Bepipred 2.0, Bepipred IDBT, Bepitope, LBtope, and MHC II predictor online server software’s based on the C-terminal region of the L1 protein. Mice antibody production was induced by subcutaneous immunisation with 50 μg of synthetic peptide and evaluated by indirect ELISA.

Results

The prevalence of BPV was higher in Tabasco, Chiapas, and Veracruz. Bovine papillomaviruses 1 and 2 were found in all representative samples. A phylogenetic tree showed that Mexican sequences were located in exclusive clades yet were highly related to international ones. The peptide immunisation induced antibody titres of 1 : 10,000/1 : 1,000,000 against synthetic peptide and whole wart lysate (WWL), respectively.

Conclusion

Co-infections of BPV-1 and -2 were found in all four states. Immunisation of BALB/C mice with BPV-1/2–derived synthetic peptide based on the C-terminal region of the major viral capsid protein L1 induced the production of specific antibodies able to recognise BPV-1/2 viral particles from bovine WWL.

Certain stimulations in the prenatal and early postnatal period may have irreversible effects on later stages of human cognitive and emotional maturity. The period between conception and birth, and the first thousand days of life are the critical periods for establishing the basic foundations for child development. Recent research showed that the fetal auditory cortex becomes mature in the third trimester of pregnancy, indicating functional fetal hearing in this period. On the other hand, there are research findings indicating to which extent prenatal and early postnatal stimulation may improve cognitive and sensory-motor development, prevent deprivation, and even epigenetic widen the limits of human perception. The paper discusses the role of prenatal auditory development in child development, and also highlighted the positive effects of prenatal and early postnatal stimulation in the improvement of child psychophysiological capacity. In that sense, the paper points to the importance of prenatal and postnatal stimulation which may lead to healthy fetal and child development.

El desempeño de los productos agroindustriales Huilenses en los mercados internacionales ha sido uno de los principales temas de análisis tanto para los hacedores de política como para productores, comerciantes y demás dependientes de este sector, es por ello que con base en datos departamentales, se pretende determinar cuáles de los productos incluidos en la apuesta agroindustrial del departamento del Huila, presentan ventajas comparativas reveladas frente a un grupo de países con los cuales el departamento mantiene relaciones comerciales significativas en estos productos; para ello se realiza el índice de la ventaja comparativa revelada (IVCR), el índice de intensidad importadora (III) y el índice de complementariedad comercial (ICC).

Los resultados evidencian que el departamento se muestra competitivo en los mercados internacionales en la comercialización de café y cacao, presentando índices de ICV sobresalientes en estos productos y afianzándolos como las especializaciones exportadoras del departamento del Huila de los productos de la apuesta agroindustrial. De igual manera, los resultados del III reflejan que el Huila exporta café al mejor destino posible para este producto; mientras que el grado de asociación comercial entre el café y el cacao que exporta el Huila es favorable (un ICC mayor a uno) respecto a las importaciones de sus socios comerciales para dichos productos.
Los hijos blancos de los dioses negros. Blanquitud, negritud y religiosidad popular en Cuba

Published: February 2023

El presente artículo indaga en las intersecciones entre etnoracialidad —con blanquitud y lo afrocubano como categorías analíticas claves— y religiosidad popular en Cuba, referida a las prácticas mágico-religiosas de origen africano, con énfasis en la santería o regla de Ocha. Partimos del análisis de lo afrocubano como un objeto teórico y cultural construido por las élites intelectuales blancas, donde las narrativas desde la blanquitud operan como definición exclusiva de lo negro y su lugar en la cubanidad. Desde estos antecedentes nos acercamos al fenómeno de creciente adscripción a las religiones afrocubanas de personas, dentro y fuera de la isla, que se consideran a sí mismas como blancas. ¿Cómo se construye y se sitúa la blanquidad en un contexto de prácticas religiosas que históricamente han estado asociadas a comunidades negras? Consideramos que la promoción de las otrora «religiones de negros pobres», con énfasis en la santería o regla de Ocha-Ifa, a nuevo estandarte de la cubanidad exige un enfoque centrado en los sujetos que garantizan la supervivencia de estas prácticas.

En el presente artículo intento entender cómo opera una «blanquidad» masculina, bogotana y propia de las clases medias altas y altas. Para esto, parto de lo disperso que puede resultar este concepto y lo anclo a una etnografía vivida en un colegio tradicional de Bogotá. En esta etnografía, analizo los escenarios en los que se habita, performa y reproduce esta blanquidad (el fútbol, la banda de guerra y los «comités»). Finalmente, concluyo que la característica central de la blanquidad es la legitimación y el ejercicio de una dominación naturalizada y violenta hacia la mayoría de la población colombiana.

Introduction. The bird cherry (Padus avium Mill.) belongs to the Rosaceae family and is common in Poland. In various parts of the plant, among others, flavonoids, anthocyanins, phenolic compounds, cyanogenic glucosides, tannins, essential oil, organic acids and sugars are present. They determine astringent, anti-inflammatory, estrogenic, anesthetic, antidiabetic, cytotoxic and antibacterial properties. Aim. Determination of antioxidant activity and sum of polyphenols in leaves, flowers, fruits and young branches of bird cherry, as well as confirmation of the presence of selected flavonoids and phenolic acids. Material and methods. The research material was leaves, flowers, fruit and young twigs of Padus avium, collected from a natural site in the Noteć Forest (near Sieraków). The contents of the sum of polyphenols in the prepared extracts were determined by spectrophotometric method using the Folin-Ciocalteu (FC) reagent and the antioxidant activity by the DPPH radical method and the FRAP method, and the presence of selected flavonoids and phenolic acids was confirmed by thin-layer and paper chromatography. Results. In water and methanol extracts, the highest content of polyphenols (%) in terms of coffee acid was found in leaves (6.91 ± 0.30%; 9.02 ± 0.34%), and the lowest in fruits (2.05 ± 0, 11%; 3.11 ± 0.11%). Water and methanol extracts from leaves showed the highest antioxidant activity and the weakest water extracts from fruit (DPPH and FRAP methods). 1D-TLC, 2D-TLC and tissue paper (PC) analysis revealed the presence of rutoside in flowers and twigs, hyperoside in leaves, flowers, fruits and twigs, and most likely ferulic and vanillic acids in fruits and twigs, chlorogenic and coffee acids in all raw materials from the bird cherry. Conclusions. The highest content of polyphenolic compounds was determined in black cherry leaves, both in water and methanol extracts. The water and methanol extracts from the leaves showed the strongest antioxidant activity. The presence of rutoside, hyperoside and some phenolic acids was confirmed in the tested raw materials.
THE UKRAINIAN PICTURE OF OSCAR WILDE: FIRST TOUCHES
Authors: ДЕРКАЧ Галина , ЧУМАК Галина , РЕШЕТУХА Тетяна
Published: February 2023

Oscar Wilde – is one of the most controversial figures in world literature, having entered into a dialogue with almost all European literatures. The reception of O. Wilde in Europe can be traced back to the late nineteenth and early twentieth centuries. Since that time, it is also possible to follow the reception of his name, ideas and works in the Ukrainian literary and critical discourse. The artistic critical response in numerous reviews, essays, literary and critical portraits, biographies, parodies of artistic life, etc. play an important role in the process of reception of the writer and his literary heritage in a foreign language culture. Translation is a special form of mediation and an important component of the perception of the literary heritage of a foreign author by a certain national literature. The choice of a work for translation is determined by the artistic needs of the perceiving literature. The synergy of literature with other art forms such as theatre, opera, cinema, book illustration, etc. can create an exceptional aesthetic pleasure. The explanation of a literary work by means of art often plays a primary role and sometimes replaces reading or completes it. The combination of all these components of reception allows us to characterize the introduction of the English-speaking Irish writer – Oscar Wilde – into the Slavic context in general and into the Ukrainian one in particular. Various ways of reception: original articles in Ukrainian periodicals, early literary reviews, critical studies, first Ukrainian translations have been analyzed in this research. The features of Wilde’s works reception in the cultural heritage of the representatives of Ukrainian literature and drama have been highlighted. The article under consideration argues that Oscar Wilde noticeably contributed to the emerging discourse around Decadence in art and literature in Ukrainian literary process. The existence of a receptive environment for the phenomenon of Oscar Wilde and his works in the Ukrainian cultural context during the 1st decade of the twentieth century is revealed and convincingly proved.

У статті йдеться про особливості формування вмінь читання у студентів китайських університетів, які вивчають українську мову як спеціальність. У методиці навчання іноземним мовам найбільш традиційною формою подання навчального матеріалу з метою його подальшого закріплення у системі вправ є викладання та вивчення мови за навчальними текстами. Лексичний склад будь-якої мови складається під впливом соціокультурних факторів і ступінь семантичних відповідностей між мовами залежить від умов життя і культури відповідних народів. Нерозуміння соціокультурної інформації іноді може заважати навіть більше, ніж незнайомі слова чи граматичні структури, і тому соціокультурні схожості та відмінності в рідній та китайській культурах повинні бути предметом обговорення і рефлексії на заняттях української мови для студентів китайських вузів. Ретельний підбір навчальних текстів і продумана система вправ з опорою на навчальний текст допоможуть усунути цю проблему.У процесі вивчення української чи будь-якої іншої іноземної мови важливими є автентичні тексти як важливий засіб навчання. Робота з автентичними текстами відіграє провідну роль у пізнанні культури країни, мову якої вивчають, у створенні мотивації, підтримання інтересу, забезпеченні взаємозв’язку навчання із життям.

Trajectory Optimization of a Partially Reusable Rocket–Scramjet–Rocket Launch System Including Fly-Back

Published: February 2023

The integration of high-speed airbreathing engines into dedicated small satellite launchers may allow for some of the stages of the launch system to be reused, resulting in improved cost efficiency and turnaround times. Designing a trajectory of this type is challenging, due to the high number of competing performance drivers and design constraints, which are often in opposition with each other between the different modes of flight (i.e. airbreathing, rocket, and glide). In this work the design of the trajectory for a partially airbreathing rocket–scramjet–rocket multistage launch system is studied by generating optimal trajectories using the pseudospectral method of optimal control for maximum payload-to-orbit. This optimization simultaneously determines the ascent of all three stages, as well as the return trajectory of the scramjet stage within the trajectory optimization. It is found that the scramjet accelerator is able to achieve fly-back to its initial launch site, but that it must ignite its scramjet engines during its return flight, causing this to become an important consideration in the optimal trajectory design. This work shows that the return of the scramjet stage of a rocket–scramjet–rocket launch system may be feasible, and indicates the trajectory features that may heavily influence future partially airbreathing launch system designs.
Analysis of Mars 2020 Entry Vehicle Aerothermal Flight Data
Authors: Edquist Karl T. , West Thomas K. , Mahzari Milad , Alpert Hannah S.
Published: February 2023

The Mars 2020 entry vehicle’s thermal protection system included measurements of in-depth temperature on the heatshield and backshell, and surface heating on the backshell. This paper describes the flight data and resulting analysis: subsurface temperatures at 11 heatshield and 6 backshell locations, measured total heat flux at two backshell locations, and a radiometer on the backshell to measure shock layer radiation. All temperatures were within allowable material limits. Total surface heat flux was derived from the in-depth temperature measurements at the thermocouple locations. Turbulent boundary-layer conditions occurred at nine heatshield locations and the radiometer provided evidence that heating from shock layer radiation significantly exceeded convective heating on the backshell. Computational results on the reconstructed entry trajectory are compared to the flight data. After boundary-layer transition, total heat flux from algebraic turbulence model calculations qualitatively matches the reconstructed heating, but with lower peak magnitudes. On the backshell, laminar heat flux predictions generally exceed the as-flown values by less than [Formula: see text], with shock layer radiation predicted to contribute the majority of heating. At the radiometer location, the maximum predicted radiative heat flux exceeds the measurement, with the measured value likely suppressed by ablation products on the sapphire window.
Control Moment Gyro Actuator for a Guided Projectile
Authors: Roussel Emmanuel
Published: February 2023

This paper investigates the suitability of using a gimbaled rotor actuator for trajectory control of a projectile. In this novel concept, a single-gimbal variable-speed control moment gyro is used as the sole control actuation system, allowing actuation in two orthogonal directions and two-dimensional control over the projectile’s flight path without any moving aerodynamic surfaces. A complete nonlinear model of the eight-degree-of-freedom rotational and translational flight mechanics is developed, as well as an accurate aerodynamic model for short-range trajectories. Linear models are derived for control design, and controllers are synthesized along with a steering logic to achieve control of the projectile’s roll and sideslip angles. Successful tracking of both angles is demonstrated, and a large course deviation is achieved, showing significant maneuverability and proving the viability of the concept.
The Latest Research Progress of Micro-Nano Dispersion System Conformance Control Technology–From Theoretical Research in Laboratory to Field Trail
Authors: Sun Zhe , Wang Xiujun
Published: February 2023

Although polymer flooding technology has been widely applied and achieved remarkable effect of increasing oil. Yet the "entry profile inversion" phenomenon occurs inevitably in its later stage, which seriously affects the development effect. The dispersion system is a novel flooding system developed in recent years. Due to its excellent performance and advanced mechanism, it can slow down the process of profile inversion, and achieve the goal of deep fluid diversion and expanding swept volume.

The dispersion system consists of dispersion particles and its carrier fluid. After coming into porous media, it shows the properties of "plugging large pore and leave the small one open" and the motion feature of "trapping, deformation, migration". In this paper, the reservoir adaptability evaluation, plugging and deformation characteristics of dispersion system in pore throat is explored. On this basis, by adopting the microfluidic technology and CT tomography technology, the research on its oil displacement mechanism is further carried out. Furthermore, the typical field application case is analyzed.

Results show that, particles have good performance and transport ability in porous media. The reservoir adaptability evaluation results can provide basis for field application scheme design. Through microfluidic experiments, the temporary plugging and deformation characteristics of particles in the pore throat are explored. Also, the particle phase separation occurs during the injection process of dispersion system into the core, which makes the particles enter and plug the large pore in the high permeability layer. Therefore, their carrier fluid displace oil in the small pore, which works in cooperation and causes no porous media and the distribution law of remaining oil during displacement process are analyzed. It shows that, particles presents the motion feature of "migration, trapping, and deformation" in the porous media, which can realize deep fluid diversion and expand swept volume. 3D macro physical simulation experiment shows that, particles can achieve the goal of enhance oil recovery. Finally, the dispersion flooding technology has been applied in different oilfields, which all obtained great success.

Through interdisciplinary innovative research methods, the oil displacement mechanism and field application of dispersion system is researched, which proves its progressiveness and superiority. The research results provide theoretical basis and technical support for the enhancing oil recovery significantly.

Published: February 2023

The construction of Zhongyuan gas storage group takes the salt layer as the caprock. Therefore, the cementing quality of the sealed salt interval is a key factor in the construction of gas storage. The cement slurry was eroded by the salt gypsum layer during the migration of the salt layer, which affects the basic performance of cement slurry, resulting in the poor cementation quality between cement sheath and salt layer. In addition, the irregular borehole in the salt layer and the expansion of well diameter make the displacement efficiency poor in the cementing process, which restricts the cementing quality of this kind of wells. At present, due to the unsatisfactory cementing quality and low excellent rate of cementing quality in the salt layer during the construction of Wen 23 gas storage, the construction of gas storage cannot be completed as planned. Therefore, in order to ensure the successful construction and service life of gas storage, the cementing technology research of big-thickness salt layer in Zhongyuan Gas Storage Group is carried out.

The salt resistant fluid loss reducer and retarder are selected through the project test, and the expansion early strength agent and toughening agent are selected. Through the compatibility research and the evaluation of the performance of cement slurry and the cementation strength of cement stone by the erosion of different salt content, a fresh-water-salt-resistant and ductile cement slurry system suitable for salt rock cementing is formed; In terms of cementing technology, we have developed well hole optimization technology, optimized leakage prevention technology in salt section and supporting high-quality sealing technology in salt layer, formed cementing technology and recommended practices for Wen 23 gas storage, and effectively ensured the primary success rate of cementing in Wen 23 gas storage. The research results of this subject have been successfully applied in 12 wells of Wen 23 gas storage and Wei 11 gas storage. The qualified rate of cementing quality has been increased from 96% to 100% and the excellent rate has been increased from 12% to 83.33%, which meets the requirements of gas storage for salt layer sealing quality and ensures the safe and efficient operation of Zhongyuan Gas Storage Group.
A Novel Capacitance-Based Emulsion Monitoring Technology
Authors: El Sharif Saba , Talaq Mustafa , Less Simone , Duval Sebastien
Published: February 2023

The objective of this paper is to introduce a capacitance-based fixture to assess and monitor crude oil and water emulsion separation kinetics in Gas Oil Separation Plants (GOSPs). The technology provides an online phase separation assessment through dielectric response analysis.

The principle of operation of this technology is based on measuring the changes in the capacitance of water/crude oil system versus time as the separation process develops. Free water, emulsion and dry crude oil have different electrical properties, and provide a unique signature to describe the physical composition of the system they form. The evolution of electrical properties of crude oil emulsions at different temperatures, and with or without the addition of chemical demulsifiers is reported.

The monitoring tool consists of a cylindrical fixture where the emulsion electrical properties are monitored during the phase separation. The fixture is connected to an Inductance Capacitance Resistance meter (LCR) to measure the change in electrical impedance of the emulsion. The fixture has a cylindrical geometry and its design was adapted to discretize the phase distribution of complex fluid mixtures. The fixture electrical properties were estimated based on its shape and material of construction, and verified by measuring the electrical impedance of fluids of known dielectric properties. The technology was tested under different conditions of temperature and concentration of demulsifier and was able to measure accurately the sample water cut and to monitor water separation kinetics in real time.

The results are driving the development of an online emulsion stability assessment tool to characterize emulsion separation kinetics at process conditions. In addition, this tool will improve the accuracy of emulsion separation measurements in crude oil processing facilities by avoiding emulsion alteration due to degassing, shearing and aging inherent to bottle test procedure.
Integrity Investigation of Macroscopic and Microscopic Properties of Non-Aqueous Foams for Enhanced Oil Recovery
Authors: Li Yibo , He Tianshuang , Zhao Jinzhou , Lin Xiang , Sun Lin , Wei Bing , Pu Wanfen
Published: February 2023

Foam flooding is a crucial enhanced oil recovery technique for profile control during the oil displacement process. The stability of the foam is the key factor for the success of foam flooding, but typical aqueous foams generally lose their stability in the presence of hydrocarbons because of their low oil tolerance. Non-aqueous foams possess outstanding stability in the presence of hydrocarbons as a result of their unique properties. However, few studies have been conducted on the stabilization mechanisms of non-aqueous foams in the presence of hydrocarbons. In this study, comparative experiments were performed to investigate differences in the stabilization mechanism between aqueous and non-aqueous foams. The results showed that a non-aqueous foam had excellent oil tolerance in a bulk foaming test. Then, the stabilization mechanisms of foams were investigated in terms of surface dilatational viscoelasticity and liquid film thinning. For a non-aqueous foam system, the maximum viscoelastic modulus of 55 mN/m occurred at a surfactant concentration of 5.0 wt%, which indicated that the foam was more stable. In a foam film thinning experiment, the thinning time of an aqueous foam system was shortened but the liquid film thickness was increased by crude oil, whereas crude oil increased the thinning time of a non-aqueous foam system but decreased its liquid film thickness. In a non-aqueous foam system, the film could remain stable for hours before rupturing, which indicated that its stability in the presence of an oil phase was excellent. These results are meaningful for the understanding of the stabilization mechanisms of oil-based foams and the employment of non-aqueous foams for enhanced oil recovery.
Carbon Storage Monitoring in Saline Aquifers Using CSEM Data
Authors: Amani Sajjad
Published: February 2023

Finding economical non-seismic methods for safe and long-term underground Carbon storage monitoring is significant. Electromagnetic methods such as controlled source electromagnetic (CSEM) are among the top economical and powerful geophysical methods for this purpose to investigate more. However, the CSEM monitoring of Carbon storage can be affected by shallower conductive materials due to their strong electromagnetic wave attenuation. So, the processing of controlled source electromagnetic (CSEM) data is investigated for monitoring Carbon storage in marine saline aquifers. High attenuation of CSEM data in the high conductive media should be considered. For safe Carbon storage, the potential for leak detection is also checked here. The solution of Maxwell's equations in a goal-oriented adaptive finite element approach is used to decrease the computational cost. This modeling method is advantageous for nonlinear inversion because the parameters can be modified to reach a certain amount of accuracy. A Carbon storage reservoir in a saline aquifer modeled for testing the CSEM monitoring method. The results confirm the high potential of this method for demonstrating the areas of target Carbon storage, its leak, and its surrounding structures.

High Carbon dioxide (CO2) content presents a serious challenge in the development of Arthit Field. Accurate resource estimation, especially in the deep reservoir sections (Lower Miocene - Oligocene), depends on the accuracy of CO2 prediction. Formulated as a manual clustering approximation, conventional CO2 prediction requires intensive labor and fails to re-calibrate the model once the latest information is acquired. This paper introduces the application of machine learning concepts to the prediction of CO2. The proposed CO2 prediction methodology leverages machine learning techniques to enhance the understanding of a known field with existing CO2 concerns. Compared to the conventional manual clustering method, the machine learning model improves accuracy and reduces time and cost in the process of CO2 prediction and, in turn, resource estimation. Although our methodology is demonstrated specifically for CO2 in Arthit Field, it is equally applicable to other parameters and fields.

Carbon Nanotube (CNTs) is a carbon-based nanoparticle regarded as the "Futuristic Materials" for advanced applications. With the initiative to produce CNTs from natural gas included the potential to reduce greenhouse gas emission in "Company X" assets, the Fluidized Bed Chemical Vapor Deposition (FBCVD) and chemical leaching was selected for production technology. During project execution, challenges in scaling up processes and equipment from laboratory data were discussed as a lesson learned for new technology development.

The CNT project began with laboratory experiments of the reaction between mimic natural gas and custom catalysts, followed by purification with acidic mixtures. Based on synthesis recipes, the prototype unit was designed and installed at the onshore plant to test with real gas under various operating conditions such as different gas ratio (HC/H2/N2), temperature etc. to verify production technique. The FBVCD reactor improves overall reactions in a short time while the new acid mixture shows high leaching efficiency, resulting in high CNTs yield and purity. With the promising results, the larger scale plant has been designed with a lean facility concept for brownfield modification.

CNTs quality is varied with production recipes which 65% yield and 95% purity for Multi-Walled CNTs with a diameter of 50 nm, approximately can be achieved by prototype unit which it is comparable with commercial grade product. Consequently, this production technique has high potential for producing CNTs from natural gas. However, some engineering points must be considered when scaling units. Some issues which had a significant impact on the initial design were encountered when scaling-up the plant. In large scale fluidized bed reactors, fluidization parameters such as velocity, flow pattern are important for equipment design. Computational fluid dynamics (CFD) based on the actual flow test is needed because the scale factor based on laboratory and prototype tests has shown different results in larger vessels. Based on CNTs purification, chemical kinetics and chain reactions are mandatory for system design. Because their effects may be undetected on a small scale, but it may lead to completely change the design concept due to more bulky mixing effects. While the examples mentioned have made the system more complex, a larger footprint with a higher project cost, but can be resolved with different approaches.

CNTs synthesis using natural gas oil&gas plants as carbon source was firstly initiated with promising results from actual field tests. This production technology is proven with higher product yield and purity compared with other conventional methods and larger scale plant is considered highly feasible. In technology development, the new things with less data are considered risky for investment, but it is a challenge that could open the new horizon for oil and gas development.

Cosmetics have fascinated the human race for ages. Cosmetics have been found to benefit in several ways such as enhancing appearance, protection, cleansing etc. If fortified with the benefit of herbal ingredients, these personal care products have proven to be a boon for many. The current study involves the formulation of seven shampoos using different herbal extracts and their comparative investigation for physicochemical and performance characteristics. Various herbal extracts using components such as coffee, fenugreek, green tea, bringaraj, onion seeds, orange oil, and lemon oil were developed and compared against the marketed standard. The effect of various extracts on the parameters such as surface tension, foam test and foam stability test, viscosity, cleansing test, sag test, dirt dispersion, wetting time and pH was successfully tested. All the formulations were found to be beneficial in eliminating oil, dirt, and dandruff, encouraging smooth, silky hair appearance, fortifying and darkening hair without altering or harming hair tresses. Our findings suggest the incorporation of fenugreek, lemon and orange peels to increase the cleansing ability. However, the inclusion of onion seeds and green tea has been found to be beneficial in the generation and stability of the foam.

Fenofibrate (FF) is a lipid-lowering agent classified in the biopharmaceutics classification system (BCS) class II with lower solubility and higher permeability. This research work deals with developing FF containing liquid self-micro emulsifying drug delivery system (L-SMEDDS) and converting it into solid SMEDDS (S-SMEDDS) using a lyophilization technique followed by the manufacturing of tablets with enhanced solubility and dissolution rate. L-SMEDDS of FF were manufactured using Tween 80, oleic acid, and transcutol. With the help of the lyophilization technique, this L-SMEDDS was converted to S-SMEDDS using microcrystalline cellulose and finally, immediate-release tablets were developed using S-SMEDDS. The L-SMEDDS showed excellent stability due to zeta potential of -1.69 mV and a globule size of 250 μm. The lyophilized S-SMEDDS of FF showed nearly 58-fold solubility enhancement in distilled water in comparison to pure FF due to the formation of amorphous material confirmed in the X-ray diffraction (XRD) study. The F9 formulation showed 100% drug release within 40 minutes with enhanced dissolution properties compared to conventional tablets. The optimized formulation was robust and stable at the accelerated condition for 3 months. The current research work demonstrates lyophilization as a potential approach to convert the L-SMEDSS to a S-SMEDDS with an enhanced solubility and dissolution rate.
