Calophyllum inophyllum L. (Calophyllaceae), locally called “tamanu” in French Polynesia, is an evergreen pantropical tree growing mostly along the seashores. Its barks, leaves, and fruits are still used in traditional medicine. The oil expressed from the nuts has been also traditionally used. Tamanu oil is topically applied on skins as well as mucous membrane lesions. This oil is especially recommended to heal all kinds of skin ailments. Bioassays and different assessments of Tamanu oil revealed numerous biological activities (antioxidant, anti-inflammatory, antibacterial, wound healing…), so bringing scientific evidence of beneficial effects of this oil on human skin healing. Such biological properties may explain the use of tamanu oil as an active cosmetic ingredient recorded as “Calophyllum inophyllum seed oil” by the INCI (International Nomenclature of Cosmetic Ingredients). Most of the bioactive properties of tamanu oil are attributed to oil composition including the presence of resinous compounds in tamanu oil beside common fatty acids, which constitutes a unique characteristic of this healing oil. Actually, resinous part of tamanu oil is known to contain bioactive secondary metabolites mostly constituted by neoflavonoids including pyranocoumarin derivatives. Herein, chemical constituents and biological properties of tamanu oil are presented with a focus of its traditional use inspiring modern valuations related to cosmetic field.

Aims: Tamanu is a plant oil derived from the fruit and seeds of the Calophyllum inophyllum tree. Although scientific data on tamanu oil are limited, it is recommended worldwide for the treatment of abrasions, burns, diabetic wounds and scars. This study aimed to compare the wound healing efficacy of the topical use of tamanu oil with a reference drug in rats. Methods: Uniform wounds were induced on the dorsum of 21 rats, randomly divided into three groups. The control group received normal saline; the tamanu group received tamanu oil; and the centella group was treated with Centella asiatica. Wound healing was clinically evaluated using wound healing scoring and wound contraction. A biopsy was taken from the wound sites of each rat on days 7, 14 and 21 for histopathological evaluation. Results: Wound contraction was significantly lower in the tamanu group compared with the other groups. On day 7, the intensity of macrophage infiltration and mature granulation tissues were significantly higher in the centella and tamanu groups than in the control group. Fibrosis and collagen density were higher in the tamanu group than the other groups on day 7. Conclusion: In wound healing in rats, tamanu oil accelerated the formation of macrophage-granulation tissues-fibrosis and resulted in less wound contraction.

The natural product of tamanu oil is valuable in medicine and cosmetic. In this study, the tamanu oil was extracted by supercritical CO2 (sCO2) and Soxhlet (using hexane solvent) methods. The fatty acids and coumarins compound of the obtained tamanu oil were analyzed by gas chromatography–mass spectrometry (GC-MS). The antibacterial and anti-inflammatory activities were also investigated by the diffusion method and performed on the white mice ears (Swiss albino). Content of fatty acid in tamanu oil extracted using sCO2 (72.62 %) was higher than that using Soxhlet method. The compound of coumaron (2H-1-bezopyran-2-one, C9H6O2) was identified belonging the simple coumarin group and its content in the tamanu oil extracted using sCO2 was the highest (169.69 μg/g), 1.79 and 2.04 times as much as that using Soxhlet method and the commercial oil, respectively. Besides, the results of investigation of the antibacterial activity suggested that the tamanu oil extracted using sCO2 was able to against some of strains namely: Staphylococcus aureus (S. aureus) ATCC 25923, S. aureus ATCC 29213, methycilin-resistant S. aureus (MRSA) ATCC 43300, and Pseudomonas aeruginosa (P. aeruginosa) ATCC 277853. In term of the anti-inflammatory activity, the tamanu oil extracted using sCO2 was anti-inflammatory effectively with reducing flammatory: 21.41 – 25.39 % as for the thickness of mice ears and 33.88 – 39.40 % as for the weight of mice ears.

Tamanu oil, derived from the nut of Calophyllum inophyllum L., has been traditionally used to treat various skin-related ailments. In recent years, this oil is increasingly gaining popularity as researchers continue to search for novel natural alternative therapies for various skin diseases. There have been a number of in vitro and in vivo studies investigating various skin-active properties of tamanu oil, and it has been proven to have potent anti-inflammatory, antioxidant, antimicrobial, analgesic, and even wound-healing abilities. These properties make tamanu oil an especially interesting candidate for the treatment of atopic dermatitis (AD). This multifaceted disease is marked by the disruption of the skin barrier function, chronic inflammation, and skin microbiome dysbiosis with limited treatment options, which is free from adverse events and inexpensive, making it desperate for a new treatment option. In this review, we examine previous in vitro and in vivo studies on AD-relevant pharmacological properties of tamanu oil in order to evaluate the potential of tamanu oil as a novel treatment option for AD.

Tamanu oil from Calophyllum inophyllum L. has long been used in traditional medicine. Ethanol extraction was found the best strategy for recovering bioactive compounds from the resin part of Tamanu oil, yielding two neutral and acidic resins fractions with high phenolics, flavonoids and pyranocoumarins concentrations. A further cascade of LPLC/HPLC separations of neutral and acidic resin fractions allowed identifying fifteen metabolites, and among them, calanolide D and 12-oxocalanolide A (both in neutral fraction) were first identified from a natural source. All these extracts, subfractions and isolated metabolites demonstrated increased free radical scavenging, antioxidant, anti-inflammatory, antimicrobial and antimycobacterial activity compared to Tamanu oil and its de-resinated lipid phase. Overall, these results could promote resinous ethanol-soluble Tamanu oil extracts as a useful multifaceted and renewable medicinal resource.

BackgroundDifferent parts of the treeCalophyllum inophyllumL. (nuts, leaves, roots, bark, fruits, nut oil and resin) are used as traditional medicines and cosmetics in most of the Pacific Islands. The oil efficiency as a natural cure and in traditional cosmetics has been largely described throughout the South Pacific, which led us to investigateC. inophyllum’s chemical and genetic diversity. A correlative study of the nut resin and leaf DNA from three distinct archipelagos in the South Pacific was carried out in order to identify diversity patterns inC. inophyllumacross the South Pacific.MethodsCalophyllum inophyllumplants were sampled from French Polynesia, New Caledonia and Fiji. We extracted tamanu oil (nut oil) resin for chemo-diversity studies and sampled leaf tissues for genetic studies. We applied an analysis method designed for small quantities (at a microscale level), and used High Performance Liquid Chromatography (HPLC) to establish the chemo-diversity of tamanu oil resin. In-house standards were co-eluted for qualitative determination. Genetic diversity was assessed using chloroplast barcoding markers (the Acetyl-CoA carboxylase (accD) gene and the psaA-ycf3 intergenic spacer region).ResultsOur HPLC analysis revealed 11 previously known tamanu oil constituents, with variability among plant samples. We also isolated and characterized two new neoflavonoids from tamanu oil resin namely, tamanolide E1 and E2 which are diastereoisomers. Although genetic analysis revealed low genetic variation, our multivariate analysis (PCA) of the tamanu oil resin chemical profiles revealed differentiation among geographic regions.ConclusionWe showed here that chromatographic analysis using formalized in-house standards of oil resin compounds for co-elution studies against oil resin samples could identify patterns of variation among samples ofC. inophyllum,and discriminate samples from different geographical origins.

Abstract The repellency to female Stomoxys calcitrans (L.) (Diptera: Muscidae) of 21 essential oils (EOs) alone or in combination with Calophyllum inophyllum L. (Clusiaceae) nut oil (tamanu oil) was examined using an exposed human hand bioassay. Results were compared with those of commonly used repellent N,N-diethyl-3-methylbenzamide (DEET). In tests with six human male volunteers at a dose of 0.5 mg/cm2, patchouli (protection time [PT], 3.67 h) was the most effective EO but less active than DEET (4.47 h), as judged by the PT to first bite. Very strong repellency also was produced by clove bud, lovage root, and clove leaf EOs (PT, 3.50–3.25 h), whereas strong repellency was obtained from thyme white EO (2.12 h). Thyme red, oregano, and geranium EOs exhibited moderate repellency (PT, 1.24–1.11 h). At 0.25 mg/cm2, protection time of clove bud, clove leaf, and lovage root EOs (PT, ≈1 h) was shorter than that of DEET (2.17 h). An increase in the protection time was produced by binary mixtures (PT, 2.68–2.04 h) of five EOs (clove bud, clove leaf, thyme white, patchouli, and savory) and tamanu oil (0.25:2.0 mg/cm2) compared with that of either the constituted essential oil or tamanu oil alone (PT, 0.56 h). The protection time of these binary mixtures was comparable with that of DEET. With the exception of savory EO, the other EOs, tamanu oil, and binary mixtures did not induce any adverse effects on the human volunteers at 0.5 mg/cm2. Thus, binary mixtures of essential oils and tamanu oil described merit further study as potential repellents for protection from humans and domestic animals from biting and nuisance caused by S. calcitrans.

Tamanu (Calophyllum inophyllum L.) oil is a non-food oil used in traditional medicine, and with potential applications in the pharmaceutical and cosmetic industry. However, this oil, obtained by pressing the nuts, is being used as crude oil, in spite of a variable but large amount of non-lipids (called resin) being entrained. Although these should not be seen as impurities owing to their known bioactivity in many fields, not only they are responsible for the poisonous nature impeding human consumption in addition to bad smell, but they contribute to the poor oil quality, especially low stability and associated short shelf life. The present study aimed at purifying a crude tamanu oil sample through a combination of simple steps: deresination with ethanol, degumming using hot water, neutralization (KOH), bleaching with activated carbon, and deodorization. Ethanol 96% was more efficient for deresinating, compared to methanol, resulting in the extraction of 44–46% w/w of resin within 10 min (temperature 40 °C; oil:ethanol 1:1.5 w/v). Oil quality was checked in the industrial crude sample and in the fully refined product. The applied process strongly improved the color from dark brown to light golden yellow, decreased the acid value (62 down to 0.11 mgKOH/g of oil), and the viscosity (181 to 130 mPa.s). The saponification value was lowered from 206 to 180 mgKOH/g oil. The peroxide value was only slightly lowered from 85 to 55 mgO2/kg oil, thus pointing out the peculiar chemical nature of tamanu oil. Improving this important quality parameter would require additional research work, together with fine-tuned optimization of experimental conditions for a panel of crude oil samples; this was out of the scope of present work. This preliminary study shows that refining steps widely applied at industrial scale could help improving the quality of tamanu oil – an underused natural feedstock – for enhanced application in health and cosmetic fields.

This chapter discusses how the arrival of Croton water in 1842 not only gave the city potable water, it supplied the firemen with a reliable source to fight the flames. It was hoped that an accessible water supply would make the city safer. Even so, blazes still flared up. Sadly, the Bowery Theatre caught fire for the fourth time in April 1845, two and a half years after the Croton celebration. And then three months later, the new aqueduct system received a serious test when a fire broke out at J.L. Vandoren's sperm-oil store on New Street. While what became known as the Great Fire of 1845 destroyed 345 buildings, wiped out firms like Philip Hone’s American Mutual Insurance company, and brought physical, personal, and financial damage to many, the Croton water supply proved its worth. At the same time, the chapter explores how the volunteer fire department had become a problem for the city. While the men had zealously committed themselves to their jobs, their fire houses had developed into entrenched and troubling centers of entitlement, and would give future Tammany boss William Tweed his springboard to power.

El presente artículo tiene como objetivo analizar la calidad de vida laboral como reto del trabajo decente frente al COVID-19 en las MIPYMES en Latinoamérica. Se trata de una investigación teórica, documental, descriptiva, reflexiva, analítica, apoyada en una metodología cualitativa basada en la revisión de material y autores que han sintetizado la situación actual de este tipo de empresas, cuantificando resultados y consolidando cifras que sirven para interpretar la perspectiva actual de este sector empresarial. Representa un avance de investigación en el tema de calidad de vida dentro de las empresas en tiempos de pandemia donde las condiciones habituales se ven afectadas sin que esto oculte la responsabilidad social interna que tienen todas las empresas sin importar su tamaño o área de negocio. Entre los autores que sustentan los argumentos teóricos se encuentran Durán, (2011), CEPAL (2020), OIT (2018), OMS (2014) entre otros. Entre las consideraciones finales se propone a la calidad de vida como determinante para un trabajo digno y como la fuerza laboral que integra las MIPYMES de América Latina se encuentran en un momento de gran afectación debido a la falta de planeación estratégica en unos casos y en otros la transversalidad del escenario extraordinario, planteado por la pandemia la cual ha obligado a cerrar un porcentaje importante de este sector empresarial en la región.

Abstract Because of the high temperatures involved, undesirable ignition events can happen during gas turbine operation, often necessitating expensive down time and repairs. The ignition events are frequently linked to the lubricant, a flammable mixture of large hydrocarbons with a very low vapor pressure. To understand better the role of the lubricant in such ignition events, increased understanding of the fundamental thermal and oxidation characteristics of such oils is needed. To this end, a suite of different tests has been set up and demonstrated at the TEES Turbomachinery Laboratory at Texas A&M University (TAMU) to study various aspects of lubrication oil breakdown and oxidation at elevated temperatures, mostly those related to their coking and ignition behaviors. Five types of tests have been implemented: ignition delay time measurements using a shock tube; hot surface ignition (HSI); autoignition temperature (AIT) determination; thermal cook-off under controlled heating; and a high-temperature coking experiment. Such tests can be used both for fundamental understanding of how lube oils burn and for comparing the reactivity of various types and grades of oil. Each technique at TAMU is briefly described in this paper as they pertain to gas turbine lube oils, and sample results are presented for a common lubrication oil, Mobil DTE 732. For this oil, the HSI tests produced a lowest temperature without ignition of 510°C, and in shock-tube measurements, lower-temperature ignition kinetics are observed below about 1300 K, even at 1 atm. Typical AIT values for oils have been found to be around 370°C but do vary amongst brands, types, and level of degradation. The measured temperatures for the exothermic and boiling events were measured as 166±2 °C and 277±4 °C using the cook-off rig.

The Thunder Horse Field targets Middle Miocene deepwater turbiditic reservoirs. Despite of being prolific, the mapping of the ~180 m thick, partly amalgamated reservoir sandstones is challenging. Seismic quality is reduced by the presence of salt structures. The salt overburden and high formation pressure requires the use of heavy mud weights and oil-based drilling fluids, which limit the resolution and interpretation potential of borehole image logs (BHI). Halokinetic movements caused significant post-depositional deformation of the already complex gravity- driven sediment stack and the reservoir beds drape against an E–W oriented salt wall. Consequently, the assessment and removal of the structural dip component is not trivial and the evaluation of paleo-transport directions is considerably more complicated compared to undisturbed deepwater reservoirs. The intention of this paper is to bring the main results from Henry et al. (2018) into context with the eigenvector methodology from Ruehlicke et al. (2019) and to emphasize its value for reservoir characterization.

Abstract Modern casing design can reduce significant amounts of CO2 and considerable cost per well [1]. Collapse design was modernized by ISO/API Technical committee 67, Sub Committee 5, Work Group 2b (ISO/API TC67/SC5/WG2b). Modernization of burst design has so far not had the same focus and only minor changes have been made. A new burst design model has been developed to add to the collapse prediction for a complete environmental and cost effective well design tool. It is based on the theories of Lubinski [2] (1975) and presents designs using “exact von Mises ellipsis” together with the Klever and Stewart ductile rupture model [3]. This paper presents the model developed for burst design and the improvement compared to current industry practice. Inspired by the current most accurate collapse prediction model [4], the modified burst model (prototype) is the first to consider actual wall thickness to predict a more accurate internal yield of OCTG (Oil Country Tubular Goods). Investigations show that the standard 12.5% wall thickness reduction for manufacturing tolerances may be obsolete. ISO 10400 offers physical measurements and statistics of tubular properties. Following the principals by WG2b applied with the Klever & Tamano collapse prediction, there is a set of data to be used for a specific batch of tubulars or they are deducted through large quantum of measurements; ensemble Probability Density Function (PDF). The value proposed as “ensemble PDF” for wall thickness is based on more than 10 000 measurements of tubulars from 11 vendors distributed over Electrical Weld (EW) and quenched and tempered (Q&T) qualities of miscellaneous sizes and grades. The batch specific value proposed is based on more modest numbers of specimens from 4 sources but offers “minimum measured wall thickness” for all the samples. Adding to the confidence of the final design is the automated ductile burst calculation, which is one of the latest contributions to burst modeling in the industry [4] [5] [6]. It is a useful aid for the design engineer to know the potential failure mode and the limit before loss of integrity. However, burst is limited to yield because exceeding this limit may lead to loss of the pipe’s effective diameter and eventually loss of integrity. Therefore, the ductile burst prediction is proposed as a visual aid only.
