Background:
Carotid endarterectomy (CEA) is an effective intervention for the treatment of high-grade carotid stenosis. Technical preferences exist in the operative steps including the use patch for arteriotomy closure. The goals of this study are to compare the rate of postoperative complications and the rate of recurrent stenosis between patients undergoing primary versus patch closure during CEA.

Methods:
Retrospective chart review was conducted for patients who underwent CEA at single institution. Vascular surgeons mainly performed patch closure technique while neurosurgeons used primary closure. Patients’ baseline characteristics as well as intraprocedural data, periprocedural complications, and postprocedural follow-up outcomes were captured.

Results:
Seven hundred and thirteen charts were included for review with mean age of 70.5 years (SD = 10.4) and males representing 64.2% of the cohort. About 49% of patients underwent primary closure while 364 (51%) patients underwent patch closure. Severe stenosis was more prevalent in patients receiving patch closure (94.5% vs. 89.4%; P = 0.013). The incidence of overall complications did not differ between the two procedures (odds ratio = 1.23, 95% confidence intervals = 0.82–1.85; P = 0.353) with the most common complications being neck hematoma, strokes, and TIA. Doppler ultrasound imaging at 6 months postoperative follow-up showed evidence of recurrent stenosis in 15.7% of the primary closure patients compared to 16% in patch closure cohort.

Conclusion:
Both primary closure and patch closure techniques seem to have similar risk profiles and are equally robust techniques to utilize for CEA procedures.

The Kyaukmyet prospect is located near the main ore bodies of the Kyisintaung and Sabetaung high-sulfidation Cu-Au deposits, Monywa copper-gold ore field, central Myanmar. Lithologic units in the research area are of mainly rhyolite lava, lapilli tuff and silicified sandstone, mudstone and siltstone units of Magyigon Formation which hosted to be polymetallic mineralization. Our field study recorded that epithermal quartz veins are hosted largely in rhyolite lava and lapilli tuff units. Those quartz veins show crustiform, banded (colloform), lattice bladed texture and comb quartz. The main objectives of the present research in which fluid inclusion studies were considered to conduct the nature, characteristics and hydrothermal fluids evolution from the epithermal quartz veins. In this research, there are three main types of fluid inclusions are classified according to their phase relationship (1) two-phase liquid-rich inclusions, (2) the coexisting liquid-rich and vapor-rich inclusions, and (3) only vapor-rich inclusions. Microthermometric measurements of fluid inclusions yielded homogenization temperatures (Th) of 148–282 °C and final ice-melting temperature (Tm) of -0.2°C to -1.4°C . The value of (Tm) are equal to the salinities reaching up 0.35 to 2.07 wt % NaCl equiv. respectively. Estimation formation temperature of the quartz veins provide 190°C and 210°C and paleo-depth of formation are estimated to be between 130m and 210m. Petrography of fluid inclusion and microthermometric data suggest that fluid boiling as well as mixing processes were likely to be happened during the hydrothermal fluid evolution at the Kyaukmyet prospect. According to the characteristics of many parameters including petrography of fluid inclusion, microthermometric data, paleo-depth, evidence of quartz vein textures and types of hydrothermal alteration from the Kyaukmyet prospect allows to interpret these data to be the low-sulfidation epithermal system.

Communication is essential to providing quality primary care. Linguistic concordance between patients and physicians has been linked to improved health outcomes and greater patient satisfaction. Although Canadian Francophones often struggle to access linguistics concordant health services, the concept of the active offer of French Language Services (FLS) has emerged as a means of ensuring the availability of such services and improving the francophone patient experience. However, the impact of language concordance and the active offer of FLS on patient satisfaction among Ontario Francophones remain largely unknown. Patient satisfaction surveys were collected as part of a continuing education program targeted at family physicians in Northeastern Ontario. Participating physicians distributed patient surveys consisting of select patient satisfaction questions from the Physicians Achievement Review (PAR) and select questions from the Active Offer of French Language Services in Minority Context Measure. Valid surveys were received from 235 patients. Just under half of these (44%) identified as Francophones, 62.6% had a French-speaking family physician; however, only 17.2% reported regularly speaking in French with their family physician. As hypothesized, there was a consistent tendency for Francophones who experience stronger linguistic concordance with their family physician to report higher satisfaction scores. Francophones who regularly speak French with their family physicians were more satisfied ( = 4.63) than those who rarely/never speak French ( = 4.29, F(1; 83) = 4.852; p < 0.05). There was also a statistically significant interaction between the patients' language of preference and the service language. Francophones who prefer French and regularly speak it with their family physician (linguistic concordance; adj= 4.82) were significantly more satisfied than those who prefer French yet rarely/never speak it (linguistic discordance; adj= 4.06, F(1; 75) = 11.950; p < 0.001). Furthermore, a positive correlation between patient satisfaction and the active offer was observed in Francophones (r = 0.49, p<0.001). The present findings provide evidence of the impact of linguistically adapted health care services on the satisfaction of Ontario Francophones and suggest that patient satisfaction may be improved through the active offer of FLS. A larger and more diverse sample is required to confirm these findings.

Published: January 2022

The palynological study of the Jambi Sub-basin, South Sumatera is carried out to construct biostratigraphy of the identifi ed formation. The palynological analysis provides an age interpretation as well as environment of depositional interpretation. The study uses outcrop samples which were collected from Merangin River, Muara Jernih and Mengupeh areas. The age of the studied sediment ranges from Early to Middle Miocene. The top Middle Miocene age is identifi ed by the occurrence of pollen Florschuetzia levipoli and Florschuetzia meridionalis, whilst the base of Early Miocene is marked by the appearance of nannoplankton Sphenolithus compactust. The studied sediment cropping out at the Merangin River and Muara Jernih area interpreted as Talang Akar Formation was deposited in a lower delta plain to delta front during Early Miocene. In the Mengupeh area, this sediment shifted landward into upper delta plain to lower delta plain environment during Middle Miocene.

Published: January 2022

Tolo Bay is located between East Arm and Southeast Arm Sulawesi, reaching a water depth of up to 3500 meters below sea level. Regionally, this block is situated within Banggai Basin where some gas and oil fi elds are already in production. The closest fi eld is Tiaka Oil Field located about 125 kilometers northwest of the study area. A geo-science review has been conducted to clarify the potential existence of hydrocarbon in this block. Based on previous reports, papers, and subsurface data from the Directorate General of Oil and Gas, the study area is located within the collision area between Banggai-Sula Microcontinent and Sulawesi. This collision occurred during Late Creataceous and Middle Miocene periods. During drifting phase a sedimentation process occurred at the front of the Banggai-Sula Microcontinent. This sediment is potentially source rock and reservoir rock. Meanwhile, during the drifting phase the study area is interpreted as located at the southern part of Banggai-Sula Microcontinent. This different tectonic setting will impact on the type of sedimentary rock, hence source rock and reservoir rock occurrence in the study area is still unclear. As source rock and reservoir rock within the study area are unclear, hydrocarbon explorations will be very risky. In order to reduce exploration risk, it is proposed to conduct geological and geophysical studies using the latest seismic data that was surveyed by PT. TGS – NOPEC and PT. ECI – PGS.

Published: January 2022

The Government of Indonesia will implement the mandatory policy on the use of Diesel Fuel and Biodiesel mixture with minimum 20% volume of biodiesel (B-20) start from 2016. From technical point of view, compatibility issue becomes one of the problems to be considered by automotive industries. The concern relate with solvent characteristic of biodiesel, which cause the biodiesel and its blends react with the parts of fuel system, especially the elastomers. This work is aimed to identify the material constructed the fuel system parts, including metal and non-metal parts, which has good compatibility to biodiesel blends up to B-20. Identifi cation of the parts material was done by FTIR and DSC for non-metal parts and by XRD and XRF for metal parts. The immersion test is used to compare the effect of fi ve biodiesel-diesel fuel blends (B-0, B-5, B-10, B-15, and B-20) to the physical change of metal and non-metal parts of diesel fuel system in a 2500 hours test period. The physical change being checked is the weight of the parts. The result obtained that for immersed metal parts, the change of weight occurred in the range of 0.007% to 0.595%. The higher weight change obtained by non-metal parts in the range of 0.001% to 13.85%. The lowest change was shown by metal parts consists of an alloy of CuO, Al2O3 and SiO, whether for non-metal parts was shown by a polymer type of Fluoroviton A. Through FTIR analysis we also observed that fuels composition before and after immersed with the tested parts were not change signifi cantly means that effect of solvent characteristic of biodiesel in the fuel mixture is negligible.
EFFECT OF ACTIVATION TEMPERATURE AND ZnCl2 CONCENTRATION FOR MERCURY ADSORPTION IN NATURAL GAS BY ACTIVATED COCONUT CARBONS
Authors: Rosmayati Lisna 
Published: January 2022

Elemental mercury from natural gas has increasingly become an environmental concern due to its high volatility and toxicity. Activated carbon adsorption is an effective mercury control method. Mercury content in natural gas should be removed to avoid equipment damage in the gas processing plant or the pipeline transmission system. This research describes the process of mercury removal from natural gas by coconut active carbon impregnated with ZnCl2. Activation temperature and ZnCl2 solution concentration are significant affect the mercury adsorption capacity. Charcoal was prepared from coconut shell and activated at 500, 700 and 900oC in constant fl ow of nitrogen. The effect of activation temperature and ZnCl2 concentration for mercury adsorption on adsorbent show that the adsorption ability of adsorbent is affected by increasing activation temperature up to an optimum temperature of 700oC. Ability of adsorption increases with increasing ZnCl2 concentration and mercury adsorption was optimum at 7% concentration of ZnCl2. The results indicated that the adsorption capacity of mercury in natural gas by activated carbon-impregnated chlor is very signifi cant. The conclusion of this paper is that optimum activation temperature 700oC and 7% ZnCl2 impregnated on adsorbent can improve the mercury adsorption in natural gas.

The use of biodiesel as fuel in light- and heavy-diesel engine vehicles in general will negatively affects the lubricant performance. the changes in lubricants properties during the use of B20 were investigated. Two type of vehicles engines were used, namely heavy duty and light duty diesel engines. The road test wascarried out until 40,000 km, while the lubricant was drained and analysed only for 10,000 km of distances. The laboratory test was conducted to observe both fresh and used lubricants. The results show that the biodiesel dilutions were less than 2% both in light- and heavy-duty diesel engines. The kinematic viscositiesof 4 samples of used lubricants in light-duty diesel engine were decreased in the ranges of 0.58 – 7.5%, while in heavy-duty diesel engines were 4.66-16.04% from the initial values. The decreasing of TBNs were less than 14% in light-duty diesel engine and fewer than 16% in heavy-duty diesel engine fuelled by biodiesel (B20). Meanwhile, the acidity of used engine oil was increased until 173% for light-duty diesel engine and 63% heavy-duty diesel engine compare to the initial values. The results show that the metal additives decreased while wear metal increased. According to this study, the increasing of wear metal (copper) in the used lubricants were less than 23% in light-duty diesel engine and lower than 26% in heavy-duty diesel engine fuelled by biodiesel (B20). Meanwhile, the lead contents of used engine oil were increased to 3.2 ppm in heavy-duty diesel engine and was not detected in light-duty diesel engine. After all, this work found that the lubricants exhibit good performances in the light- and heavy-duty diesel engines fuelled by B20. The changes of some critical properties were still in the acceptable values regarding to the specification as required in the SNI-7069-5 (2021).

This paper primarily is focusing on presenting the non-productive time overview and any kind of non-productive time that can be reduced by real-time data technology, real-time data transmission and visualization infrastructure which supports the processes of aggregation, transmission, and visualization; the example of multipurpose implementation and further innovation and improvements that can be made within the real-time data transmission and visualization, such as real-time reservoir footage calculation during geosteering and drill-time calculation to pick the formation tops and casing point; the challenges and limitation while using real-time data, such as VSAT and local network connectivity issue; and future target and improvement of real-time data usage especially to make an artifi cial intelligence system to predict the potential feature, such as formation or drilling problem while drilling. All of those stuff s could be found by literature study and direct professional experience while handling real-time data system. This technology will inspire the user to design their own solution for their operations. Despite the signifi cant advances on real-time data transmission and visualization, there is signifi cant room to fully use itspotential for advanced workfl ows and the usage of real-time data technology which was proven to reduce the Non-Productive Time that could save the operational cost. We believe that the utilization of real-time data transmission and visualization will defi nitely increase the effi ciency of the drilling operations, especially for multiple wells operations.

Published: January 2022

The Jambi Sub-Basin is part of the prolifi c South Sumatra Basin which has been proven to produce conventional oil and gas in large quantities. In the basin, Talang Akar Formation (TAF) is believed to be the dominant source rock for commercial hydrocarbons. That means the TAF has potential as shale play resulting oil and gas. Generally, shale plays of the TAF was deposited on littoral-neritic environment during late period of syn-rift until early post-rift at Late Oligocene - Early Miocene. Based on well log analysis, identifi cation characters shale plays of the TAF in the Jambi Sub-Basin have good character as source rock reservoir. Several wells showed that early maturity level happened at depth less than 2000m. Most of TOC, S2 and HI values exist in the range of (1-10) wt%, (0.25 - 10) mg/g rock and (50 - 400) mg HC/ g TOC respectively. Shale plays of the TAF tend to have Type II, II / III and III kerogen. Most of existing wells are not located in the basin center. The geophysical methods such as seismic inversion and seismic attribute can be applied to predict the TOC (Total Organic Carbon) and brittleness index (BI) distributions especially in the basin center. Geologically, the shale plays quality in center of basin was interpreted better than the fl ank. Age of the shale in the Jambi Sub-Basin is relatively much younger when compared to shale in North America. This fact is suspected to cause the TAF shale play to be relatively less brittle. The data processing result shows that the brittleness index values of shale plays tend to be in the range of 40% - 70%.

Published: January 2022

El objetivo del trabajo radica en la importancia de dar valor a los pueblos indígenas presentando sus expresiones culturales y así contribuir a parar la discriminación y marginación a través de su conocimiento. Tras la conquista española, el desarrollo regional tuvo en la explotación de minas su principal actividad económica, lo que motivó el establecimiento de poblados y haciendas que se beneficiaron de la explotación de metales preciosos, del sub suelo, del uso del Henequén y la extracción del pulque.
En la época de la conquista se pretendió construir una “república de indios” para conservar, por un lado, los elementos culturales autóctonos que no fueran contrarios a los preceptos cristianos, y por el otro, incorporar los nuevos contenidos religiosos a la vida cotidiana de su nueva feligresía. Para llevar a cabo ese objetivo congregaron a los indígenas dispersos en la profundidad de las serranías y de las cuevas casi inexpugnables para formar pueblos.
En la etapa de la evangelización los agustinos fundaron hospitales anexos a sus conventos y aprovecharon los conocimientos de la herbolaria prehispánica, aplicaron la terapia ocupacional que convirtió a sus fieles en excelentes artesanos y participaron en los trabajos de construcción de iglesias y conventos, además construyeron escuelas para los niños, grupos de coros y músicos para los oficios religiosos, Tepeji del río Hidalgo y San Ildefonso Chantepec, comunidad de Tepeji no fueron la excepción.
