Dynamics of Low-Interfacial-Tension Imbibition in Oil-Wet Carbonates
Authors: Tagavifar M.. , Balhoff M.. , Mohanty K.. , Pope G. A. 
Published: January 2019

Summary
Surfactants induce spontaneous imbibition of water into oil-wet porous media by wettability alteration and interfacial-tension (IFT) reduction. Although the dependence of imbibition on wettability alteration is well-understood, the role of IFT is not as clear. This is partly because, at low IFT values, most water/oil/amphiphile(s) mixtures form emulsions and/or microemulsions, suggesting that the imbibition is accompanied by a phase change, which has been neglected or incorrectly accounted for in previous studies. In this paper, spontaneous displacement of oil from oil-wet porous media by microemulsion-forming surfactants is investigated through simulations and the results are compared with existing experimental data for low-permeability cores with different aspect ratios and permeabilities. Microemulsion viscosity and oil contact angles, with and without surfactant, were measured to better initialize and constrain the simulation model. Results show that with such processes, the imbibition rate and the oil recovery scale differently with core dimensions. Specifically, the rate of imbibition is faster in cores with larger diameter and height, but the recovery factor is smaller when the core aspect ratio deviates considerably from unity. With regard to the mechanism of water uptake, our results suggest, for the first time, that (i) microemulsion formation (i.e., fluid/fluid interface phenomenon) is fast and favored over the wettability alteration (i.e., rock-surface phenomenon) in short times; (ii) a complete wettability transition from an oil-wet to a mixed microemulsion-wet and surfactant-wet state always occurs at ultralow IFT; (iii) wettability alteration causes a more uniform imbibition profile along the core but creates a more diffused imbibition front; and (iv) total emulsification is a strong assumption and fails to describe the dynamics and the scaling of imbibition. Wettability alteration affects the imbibition dynamics locally by changing the composition path, and at a distance by changing the flow behavior. Simulations predict that even though water is not initially present, it forms inside the core. The implications of these results for optimizing the design of low-IFT imbibition are discussed.
A New Approach to the Analytical Treatment of Steam-Assisted Gravity Drainage: A Prescribed Interface Model
Authors: Keshavarz Mohsen , Harding Thomas G. , Chen Zhangxin 
Published: January 2019

Summary
The majority of the models in the literature for the steam-assisted-gravity-drainage (SAGD) process solve the problem of conductive heat transfer ahead of a moving hot interface using a quasisteady-state assumption and extend the solution to the base of the steam chamber where the interface is not moving. This approach, as discussed by Butler (1985) and Reis (1992), results in inaccurate or sometimes infeasible estimations of the oil-production rate, steam/oil ratio (SOR), and steam-chamber shape. In this work, a new approach for the analytical treatment of SAGD is proposed in which the problem of heat transfer is directly solved for a stationary source of heat at the base of the steam chamber, where the oil production occurs. The distribution of heat along the interface is then estimated depending on the geometry of the steam chamber.
This methodology is more representative of the heat-transfer characteristics of SAGD and resolves the challenges of those earlier models. In addition, it allows for the extension of the formulations to the early stages of the process when the side interfaces of the chamber are almost stationary, without loss of the solution continuity. The model requires the overall shape of the steam chamber as an input. It then estimates the movement of chamber interfaces using the movement of the uppermost interface point and by satisfying the global material-balance requirements. Oil-production rate and steam demand are estimated by Darcy's law and energy-balance calculations, respectively. The result is a model that is applicable to the entire lifetime of a typical SAGD project and provides more-representative estimations of in-situ heat distribution, bitumen-production rate, and SOR.
With the improved knowledge obtained on the fundamentals of heat transfer in SAGD, the reason for the discrepancies between the various earlier models will be clarified. Results of the analytical models developed in this work show reasonable agreement with fine-scale numerical simulation, which indicates that the primary physics are properly captured. In the final section of the paper, the application of the developed models to two field case studies will be demonstrated.

Using Naïve Bayes Algorithm to Estimate the Response to Drug in Lung Cancer Patients
Authors: Guo Baoling , Zheng Qiuxiang 
Published: January 2019

Aim and Objective:
Lung cancer is a highly heterogeneous cancer, due to the significant
differences in molecular levels, resulting in different clinical manifestations of lung cancer patients
there is a big difference. Including disease characterization, drug response, the risk of recurrence,
survival, etc.

Method:
Clinical patients with lung cancer do not have yet particularly effective treatment options,
while patients with lung cancer resistance not only delayed the treatment cycle but also caused strong
side effects. Therefore, if we can sum up the abnormalities of functional level from the molecular
level, we can scientifically and effectively evaluate the patients' sensitivity to treatment and make the
personalized treatment strategies to avoid the side effects caused by over-treatment and improve the
prognosis.

Result & Conclusion:
According to the different sensitivities of lung cancer patients to drug
response, this study screened out genes that were significantly associated with drug resistance. The
bayes model was used to assess patient resistance.

Published: January 2019

Background and Objectives:
Multiple-Drug-Resistance (MDR) among bacteria is an
imminent problem and alternative therapies are seen as a future abode. Agarwood Oil (AO) is
described to possess antimicrobial activity besides many other medicinal utilities. This paper
discusses the antimicrobial activity of AO on MDR and non-MDR strains of microbes of 69
genera isolated from clinical and non-clinical samples.

Methods and Results:
In this study sensitivity of microbes was determined for conventional
antimicrobials and AO using disc diffusion assay followed by determination of minimum
inhibitory concentration (MIC) using agar well dilution assay. A total of 18.5% (522) strains were
found sensitive to AO. Carbapenem resistant bacterial strains were more often (p, ≤0.01) resistant
to antibiotics with 4.2 times more odds (99% CI, 2.99-5.90) of being MDR than carbapenem
sensitive strains but no difference in their AO sensitivity was observed. However, MDR strains
were more often (p, <0.001) resistant to AO than non-MDR strains. Bacteria isolated from dogs
were more often sensitive to AO than those from buffaloes, human, horse, and cattle. On the other
hand, bacteria from pigs were more often (p, ≤0.05) resistant to AO than bacteria from human,
cattle, buffaloes, dogs, wild carnivores and birds. Oxidase positive Gram positive bacteria had 4.29
(95% CI, 2.94-6.27) times more odds to be AO sensitive than oxidase negative Gram negative
bacteria. Bacillus species strains were the most sensitive bacteria to AO followed by strains of
Streptococcus and Staphylococcus. The MIC of AO for different bacteria ranged from 0.01 mg/mL
to > 2.56 mg/mL.

Conclusion:
The study concluded that MDR and AO resistance had a similar trend and AO may
not be seen as a good antimicrobial agent against MDR strains.

Background:Tobacco smoking is among the most significant predictors of cardiovascular disease and lung cancer in People Living with HIV (PLHIV). Smoking rates in this population are high, necessitating more effective smoking cessation strategies. We conducted a descriptive analysis of tobacco-related clinical and sociodemographic characteristics of smokers at a tertiary care HIV clinic in Montreal and an exploratory analysis of smoking cessation methods in order to identify potential areas of improvement in the clinic’s approach to smoking cessation.Methods:A convenience sample of patients completed a 10-minute questionnaire on tobacco-related behaviours and outcomes. Use of smoking cessation methods was compared using McNemar’s exact test with a Bonferroni correction for multiple testing (p<0.01 considered significant).Results:Seventy-two PLHIV participated. Two-thirds of our total participants were interested in quitting within six months, but the use of effective cessation strategies was low, particularly for counseling and oral therapy. Overall, oral therapy (e.g.varenicline) (16.7%) and counseling for cessation (5.6%) were used less than nicotine patches (50.0%) or ‘other’ methods (50.0%), which included abstinence and nicotine gum (p<0.001).Conclusion:Despite a small and potentially unrepresentative sample of HIV positive tobacco smokers at our clinic, this study could help guide further research aiming to determine and address barriers to smoking cessation and access to effective smoking cessation aids in PLHIV. Future studies might consider factors that affect motivation to quit, such as co-morbid mental health and substance use disorders, or the attitudes of HIV healthcare providers.

AbstrakEkonomi kreatif menjadi salah satu tulang punggung pertumbuhan perekonomian Negara. Kita dapat mengamati bahwa industri kreatif semakin aktif sehingga penyerapan tenaga kerja akan semakin tinggi dan dapat di pastikan pengangguran akan semakin berkurang. Terbukti pada tahun 2014 ekonomi kreatif berkontribusi sebesar 7,1% terhadap PDB nasional, mampu menyerap 12 juta tenaga kerja, serta memberikan kontribusi perolehan devisa negara sebesar 5,8%. Namun beberapa sub-sektor yang ada di dalam ekonomi kreatif, potensi di bidang seni (kriya, seni rupa, tari, dan musik) masih dirasa kurang maksimal. Artikel ini merupakan sebuah upaya menganalisis potensi seni di bidang ekonomi kreatif dalam memaksimalkan penjualan produk/jasa kesenian. Peneliti mencoba mengkaji potensi seni dengan menggunakan teori dari Philip Kotler, yaitu teori bauran pemasaran (marketing mix). Alat-alat bauran pemasaran (marketing mix) yang populer sering digunakan meliputi: produk (product), harga (price), saluran distribusi (place), dan promosi (promotion). Studi ini menggunakan pendekatan deskriptif-kualitatif dengan metode studi literatur.Kata kunci: produk seni, ekonomi kreatif, bauran pemasaran.
