Integrating Reservoir and Geomechanical Models to Compare the Productivity of Shale Reservoirs Using Different Fracture Techniques
Authors: Lakshminarayanan S.. , Jayakumar R.. , Safari M. R. , Huang Jian , Rai R.. , Christian S.. , Mutlu U..
Published: November 2013

The ultra-tight nature of shale gas reservoirs has made hydraulic fracturing inevitable. Whilst most of the gas industry is driven by the success of hydraulic fracturing, alternate fracturing techniques have repeatedly been overlooked. In hydraulic fracturing, only 20–30% of the injected water is recovered during clean-up, and this causes a concern over the fracture efficiency. Additionally, the overbalanced pressure during fracturing poses a threat towards damaging the fracture sand face. A potential alternative to eliminate these drawbacks is a forgotten technology-pulsed gas fracturing. The pulsed fracturing (through high pressure gas) also makes the clean-up much faster/simpler. Although the stimulated reservoir volume (SRV) resulting from pulsed fracturing might not be comparable to the one resulting from hydraulic fracturing, it is suspected that the former technique would be more efficient especially in ductile shale where the industry lacks efficient stimulation technique as hydraulic fracturing fails to be successful.

Hydraulic fracturing involves a relatively slow loading rate and this usually results in bi-wing fracture geometries. On the other hand, explosive fracturing involves very rapid loading of formation that can trigger multiple fractures. However, due to extreme stress/heat that is generated during the explosion, near wellbore region may reach the plastic limit which inhibits fracture growth away from the wellbore. The pulsed fracturing loading rate and peak load (via high energy gas or propellants) lies in between hydraulic and explosive fracturing processes. This technique has the potential to shatter ductile shale(s): in particular by triggering a ductile to brittle transition: at an optimized pulse rate at a certain depth.

Through coupling of geomechanical and reservoir models, a workflow to predict the generated fracture networks and to quantify the productivity/efficiency of the same has been established. Additionally, in order to account for the various phenomena that are expected to occur during transient production, parameters such as desorption and stress dependent permeability have been considered and are presented in this paper.

This paper serves as a platform to compare the models depicting the established process of hydraulic fracturing versus an alternate fracturing technique like pulsed gas fracturing.
Modeling the adsorption of emerging contaminants on activated carbon: classical and quantum QSAR approaches
Authors: Zhang Juan , Hofmann Ron
Published: November 2013

The adsorption of 115 emerging contaminants, mainly organic chemicals identified by the US Environmental Protection Agency's 2009 Contaminant Candidate List 3, was ranked using two published classical quantitative structure-activity relationship (QSAR) models and a newly developed quantum QSAR model. Approximately 75% of the investigated contaminants were predicted to be cost-effectively treatable, with an activated carbon usage rate below 10 mg/L. A limited experimental validation campaign was carried out by rapid small-scale column testing (RSSCT) using Lake Ontario water for eight selected compounds: 17β-estradiol, ibuprofen, diazinon, sulfamethoxazole, carbamazepine, 4-nonylphenol diethoxalyate, azithromycin and tylosin, with the activated carbon adsorption of the latter three having never been previously reported. The experimental results were consistent with the quantum chemistry model rankings.

Published: November 2013

Polymorphic Amplified Typing Sequences (PATS) is a PCR-based Escherichia coli O157 (O157) strain typing system. Here, we show that PATS compares excellently with Pulsed-Field Gel Electrophoresis (PFGE) in that both methods cluster geographically diverse O157 isolates similarly. Comparative analysis of the results obtained in this simulated “blind” study attests to the discriminating power and applicability of PATS to epidemiological/nosocomial situations.
Does SFAS No. 151 Trigger More Overproduction?
Authors: Young Chaur-Shiuh , Peng Chih-Wei , Chien Chin-Chen , Tsai Liu-Ching
Published: November 2013

This study explores whether SFAS No. 151 affects firms' production-level decisions. Although the change from ARB No. 43 (FASB 1953) to SFAS No. 151 (FASB 2004) seems trivial at first glance, using a sample of U.S. manufacturing firms from the Compustat database (SIC 2, 3) for the period 2003–2008, we document that abnormal production costs significantly increased after SFAS No. 151 became effective in 2005. The empirical evidence substantiates our hypothesis that the explicit expensing and reporting of idle facilities, as stipulated in SFAS No. 151, inadvertently further induces opportunism for excess production. Moreover, we find that firms that have limited options to indulge in accruals management, and those that have pressures to boost income, will have higher excess production after the adoption of SFAS No. 151. Supplementary analyses indicate that our results are robust with regard to controlling for sales manipulation, and to alternative explanations for excess production as well as alternative overproduction measures.

This descriptive type of cross sectional study was carried out among purposively selected 90 coronary artery bypass graft operated patients attended at cardiovascular surgery out patient department of combined military hospital, Dhaka from 01 March 2012 to 30 June 2012 with the objective to assess the quality of life by using the RAND Medical Outcomes Short Form 36 (SF- 36) questionnaire. The population studied had a mean age of 54.60 years with 92.2% were male and 7.8% were female. Most of the respondents were retired (43.3%) followed by service personnel (38.9%). Regarding educational qualification, most of them were between class VIII to SSC and 95.6% were Muslim. The mean monthly income of the respondents was Tk. 18127.78. The findings showed that post CABG respondents possessed a good level of QOL with an average score of 86.0921. The mental components score (87.8571) was found to be higher than physical component score (84.9153). It was found that the association between age and physical functioning domain of physical component was statistically significant (r= -.189*, p<0.05) and association between all other domains (role physical, bodily pain, general health, vitality, social functioning, role emotional and mental health) were statistically not significant. The study also revealed a negative correlation of total quality of life with age but positive correlation with other socio demographic characteristics (level of income, education and occupation) though all of the relations were statistically not significant. No statistically significant difference revealed with the different domains of quality of life and socio demographic characteristics. In regards to the monthly income, highest score noted in Tk. 10000-30000 income groups in all the domains. Respondents' occupation showed significant difference with the general health domain (F= 3.456, p <0.05) and physical component summary (F= 2.969, p <0.05) of the SF- 36 items. The education level showed significant difference with the physical functioning of physical component domain (F= 2.675, p <0.05). The findings showed that the highest score was for HSC education in both the components of quality of life. The post CABG respondents possessed a good level of QOL with good mental components score than physical component score. It is also revealed from the study that with increasing age the physical functioning of the patient decreases. From the study it depicts that higher education, better occupation and good monthly income of the respondents have better quality of life out come than that of others. Study on larger sample size may be carried out for more accurate results on quality of life after CABG operation.

Published: November 2013

Among hospitalized patients, the most common nosocomial infection is Urinary tract infection (UTI). The knowledge about the type of pathogens responsible for UTI and susceptibility and resistance pattern of the causative agents at a specific area may help the doctors to choose correct treatment regimen. This study was aimed to investigate the antibiotic susceptibility and resistance pattern of isolated urinary pathogens. This study was done at Anwer Khan Modern Medical College Hospital, Dhaka during January- June, 2011. Out of 498 clinical samples of urine collected, 245 (49.19%) showed significant bacterial growth. The most common pathogens isolated were Escherichia coli (142, 58.0%), Streptococcus feacalis (38, 15.5%), Pseudomonus (20, 8.2%), Klebsiella species (20, 8.2%) and Staphylococcus epidermidis (14, 5.7%). Members of the Enterobacteriaceae were 75%-100%sensitive to Amikacin and Nitrofurantoin while they were found variably sensitive to other commonly used antibiotics. Pseudomonas species were found 90% sensitive to Meropenem and 70% to Amikacin. Strep. feacalis were found 94.7% sensitive to Amoxicillin, 84.2% to Amoxiclave and 78.9% to Ciprofloxacin, 65.5% to Cephalexin, 50% to Ceftriaxone. The clinicians should use Meropenem and Amikacin selectively in cases of un-responsiveness to commonly used antibiotics.

Published: November 2013

Association of fasting plasma glucose (FPG) and post prandial plasma glucose (PPG) on hemoglobin glycation is still controversial. In this study we aimed to assess the influence of FPG and PPG on hemoglobin glycation in newly diagnosed never treated diabetic (NDNT-DM) subjects and treated diabetic (T-DM) subjects. One hundred and seventy seven diabetic subjects were included in this study. Plasma glucose concentrations were measured by hexokinase end point technique and glycated hemoglobin (HbA1c) levels were measured by modified cationexchange high performance liquid chromatography (HPLC). Univariate and multivariate linear regression models were applied to assess the relative contribution of FPG and PPG on HbA1c. Univariate linear regression analysis showed significant positive association of FPG and PPG with HbA1c in both groups. Multivariate regression model showed that ? (beta) value of HbA1c was 0.5528 (p<0.0001) for FPG and 0.3047 (p<0.01) for PPG in the NDNT-DM whereas 0.5509 (p<0.0001) for FPG and 0.1874 (p>0.05) for PPG in treated diabetic subjects. After adjustment for age and sex, beta remains statistically significant for FPG and PPG where beta value for FPG was higher for FPG than for PPG in both NDNT-TM group and T-DM groups. This study revealed that FPG has a stronger association on hemoglobin glycation as compared to PPG in diabetes mellitus.

Reproductive health is an emerging issue in Bangladesh as well as in the world. Women reproductive health is relatively a new area of health intervention in Bangladesh and recently it is an important issue. Among the women, married adolescents are particularly vulnerable regarding reproductive health problem in Bangladesh. This descriptive cross sectional study was carried among 534 married women of reproductive age by purposive sampling from 22nd to 28th December, 2012 in different villages of Dhamrai Upazila, Dhaka. Data were collected on a pretested questionnaire by face to face interview. Data were analyzed manually and by using computer. The study revealed that majority of the women had either primary (33%) or secondary level (39%) education with mean age of 29±7.33 years. Most of them (86%) were house-wives and dependant on their husband for financial support and major segment (52%) had poor monthly income (TK <9000). Among all, about 58% respondents were found having 2-4 number of children and 58% gave birth of first child during adolescence (15-19 years) with mean age of 19±3.5 years. About (79%) received TT immunization and (77%) utilized antenatal care. Most of the delivery (52%) were conducted at home by skilled birth attendant (30%) and untrained birth attendant (22%). About 31% had problems during last pregnancy. Among them adverse outcomes were Abortion (21%), PPH (22%) and Obstructed labor (28%). Reproductive health problems faced by the women included Menstrual disturbance (52%), Leucorrhoea (41%) and Urinary Tract Infections (35%). Reproductive health practice was still worse among the rural community of the study area. The study recommends formulation and implementation of effective strategies to improve reproductive health status of the rural women.

Legal term hurt means bodily pain, injury or wound and disease or infirmity caused to any person. Abrasion, bruise, laceration, fracture, dislocation, incised wound, stab wound, puncture, penetrating wound, firearm wound, bomb blast wound, burn, scald are common types of injury or hurt. Different types of weapons or means used to cause hurts are blunt, sharp and pointed weapons, firearms, bombs, heat, electricity and corrosives. For legal purposes, hurts are grouped as grievous hurt and simple hurt. There are eight categories of grievous hurt. In reporting hurt cases, the clinical state of the victim with full description of the wounds are noted and an opinion regarding their legal state i.e. whether grievous or simple, age of the injury, type of the weapon or means causing the injury, whether inflicted by others or self inflicted etc. is given. These help the court to give its judgment. There are enacted laws describing section, numbers, types of crime and their punishments.

In the era of information explosion, it is impossible for anyone to keep himself up-to-date with the literature by reading alone. Moreover there is vast amount of un-useful information added each day in the literature. Someone has to remain up-to-date with the valid and usable new information. Since its inception, journal club has been used as a useful meeting with the purposes of staying abreast of scientific publications and to judge their usability. In this article the concept of journal club and its practices were reviewed. The journal club has been proved to be a versatile program for its adaptable and multidirectional format to help the participants to develop many essential skills. It is now used as an academic program and is incorporated into curriculum in many institutes. Critical appraisal journal club models are most widely used to accomplish defined learning objectives. Evidence based journal club is one step ahead, through which practitioners judge the evidences and weigh its usability to bring a change in practice. Each institute should have defined journal club objectives for the development of students learning capability and also to develop and cultivate more skilled faculty. The practice of journal club can be adjusted and formatted according to the set goal of the organizing authority and the learning objectives of the participants.

Published: November 2013

Random Amplified Polymorphic DNA (RAPD) assay was initiated for molecular genetic analysis among 13 F3 rice lines and their parents. Four out of 15 decamer random primers were used to amplify genomic DNA and the primers yielded a total of 41 RAPD markers of which 37 were considered as polymorphic with a mean of 9.25 bands per primer. The percentage of polymorphic loci was 90.24. The highest percentage of polymorphic loci (14.63) and gene diversity (0.0714) was observed in 05-6 F3 line and the lowest polymorphic loci (0.00) and gene diversity (0.00) was found in 05-12 and 05-15 F3 lines. So, relatively high level of genetic variation was found in 05-6 F3 line and it was genetically more diverse compared to others. The average co-efficient of gene differentiation (GST) and gene flow (Nm) values across all the loci were 0.8689 and 0.0755, respectively. The UPGMA dendrogram based on the Neis genetic distance differentiated the rice genotypes into two main clusters: PNR-519, 05-19, 05-14, 05-12 and 05-17 grouped in cluster 1. On the other hand, Baradhan, 05-9, 05-13, 05-11, 05-5, 05-6, 05-1, 05-4, 05-15 and 05-25 were grouped in cluster 2. The highest genetic distance (0.586) was found between 05-4 and 05-17 F3 lines and they remain in different cluster.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16839 Progress.

Authors: Rehana S , Alam MS , Islam KS , Samad MA
Published: November 2013

The effect of BAP and IBA on in vitro regeneration of four banana cultivars viz. Amritsagar, Seeded banana, Sabri and Anajee was studied. The response of single shoot regeneration from shoot tips of four banana cultivars at different concentrations of BAP was found to be different. The cultivar Amritsagar produced the highest percentage (60 %) of single shoot at 4.0 mg/l BAP within 10-15 days. The cultivar Sabri and Anajee produced lower percentage of single shoots. Rates of shoot multiplication of Amritsagar, Sabri, and Anajee were 6-7 plantlets/explant, 2-4 plantlets/explant, and 2 plantlets/explant, respectively on medium containing 4.0 mg/l BAP after 30 days of culture. But in subsequent subculture, on the same medium, Amritsagar produced the highest number of plantlets (9 plantlets/explant) within the same period of time. The best root formation in multiplied shoots of Amritsagar was found on MS medium containing 2.0 mg/l IBA after 15 days of culture. All the in vitro cultured banana plantlets of Amritsagar survived when weaned to ex vitro conditions on soil.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16840 Progress. Agric. 20(1 & 2): 9  16, 2009

Published: November 2013

Efficacy of some botanicals viz., neem oil, karanja oil and mahogoni oil at different concentrations was determined against brinjal shoot and fruit borer (BSFB). Three botanical oils were evaluated by assessing larval mortality in laboratory. Neem oil at 4% concentration showed lowest larval survivability (26.67%) while mahogoni oil caused highest survivability (68.89%) at 2% concentration. The effect of botanical oils on larval survivability decreased proportionally with the increase of concentrations. Considering the efficacy of all concentrations the order of toxicity was neem oil>karanja oil>mahogoni oil. The effectiveness of the botanicals viz., neem oil (4%), karanja oil (4%), mahogoni oil (4%), neem cake (250 kg/ha), neem oil + neem cake (4% + 250 kg/ha) were evaluated by application at 15 days interval against BSFB in the field. The highest percentage of reduction (70.44% infested shoots/plant) of BSFB was found in neem oil + neem cake. Minimum reduction of shoot infestation by BSFB was observed in neem cake treated plot. Similiar efficacy was found in case of reduction percentage of fruit infestation by BSFB.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16847 Progress. Agric. 20(1 & 2): 35  42, 2009

Published: November 2013

A field study was conducted on the nature and extent of damage of corn earworm, Helicoverpa zea (Boddie) in two maize varieties viz. BARI Hybrid Bhutta-5 and BARI Bhutta-7. The larvae caused damage by feeding on the ear tip at silk stage and then to kernel, the larvae were mainly confined to the ear tip and excreted faecal matter. It was found that the cob infestation rate was in linear progress and the mean cob infestation was 6.50% and 6.69% in BARI Hybrid Bhutta-5 and BARI Bhutta-7, respectively. The mean length of cob infestation was 24.90% and 25.07% and the mean number of kernel damage was 24.30 and 25.43 in BARI Hybrid Bhutta-5 and BARI Bhutta-7, respectively. The average yield loss was 0.016 t/ha in BARI Hybrid Bhutta-5 and 0.017 t/ha in BARI Bhutta-7. It was revealed from the results that BARI Bhutta-7 was more susceptible to this pest.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16849 Progress. Agric. 20(1 & 2): 49  55, 2009

Prey consumption efficiency of the wolf spider, Pardosa pseudoannulata (Boesenberg and Strand) preying on brown planthopper (BPH), Nilaparvata lugens (Stål), green leafhopper (GLH), Nephotettix virescens (Distant) and drosophila, Drosophila melanogaster was investigated in the laboratory of the Department of Entomology, Bangladesh Agricultural University, Mymensingh during the period from June 2008 to April 2009. Depending on the instars and maturity, the spiders were grouped into four different age classes, namely Class I (3rd and 4th instars), Class II (5th and 6th instars), Class III (7th and 8th instars) and Class IV (egg bearing female). When the spiders of each class was supplied with sufficient number of BPH, GLH and Drosophila then the order of the prey consumption of Class I spider was BPH > drosophila > GLH and the order of the prey consumption of Class II, Class III and Class IV were BPH > GLH > drosophila. But in two cases BPH was highly preferred over drosophila and GLH in a mixed diet.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16850 Progress. Agric. 20(1 & 2): 57  62, 2009

Published: November 2013

An experiment was conducted at farmers field of Kushtia sadar MLT site under AEZ 11 during three consecutive years at 2001-2004 to find out the rate of nutrients (NPKS) for Onion (Taherpuri), T. aus (IR-50) and T. aman rice (BR-11) to NPKS on the yield under AEZ11. Four different levels of NPKS were assigned in RCB design with 4 replications. Average of three years study reveals that a considerable response of Onion, T. aus and T. aman rice to NPKS was observed. However, the response to P, K and S was more distinct in comparison to N. Similarly, the response was more evident in Onion compared with T. aus and T. aman rice. Yield of Onion increased up to the application of 120, 43, 120 and 20 kg/ha of N, P, K and S, respectively. Yield of T. aus and T. aman rice increased up to the application of 70, 18, 34 and 10 kg/ha of N, P, K and S, respectively. From the regression analysis it was found that the relationship was almost quadratic in nature. The application of 115-40-118-18 kg NPKS/ha for Onion, 63-19-29-9 kg NPKS/ha for T. aus rice and 65-17-33-9 kg NPKS/ha for T. aman rice was the most economically optimum fertilizer dose in the High Ganges River Floodplain Soil under AEZ 11.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16851 Progress.

Published: November 2013

A total of 17 stool samples were collected from enteric fever suspected patients of Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Results of morphological, biochemical examinations and pathogenicity test revealed Escherichia coli (47%), Klebsiella spp. (41%), Citrobacter spp. (29%). In cultural examination, all Escherichia coli showed metallic sheen on EMB agar, Klebsiella spp. showed moist shiny mucoid colonies and Citrobacter spp. showed large convex colorless dwarf colonies on MacConkey agar. In biochemical examination, all the isolates fermented five basic sugars with the production of acid and gas where the Citrobacter spp. were late lactose fermenter. Escherichia coli was indole and MR positive but V-P negative, Klebsiella spp. were V-P positive but MR and Indole negative and Citrobacter spp. were MR positive but V-P and Indole negative. All isolated bacterial species were sensitive to ciprofloxacin but resistant to amoxicillin. Salmonella typhi or Salmonella paratyphi organisms were not present in the stool samples examined. This may be due to collection of samples from patient having antibiotic therapy with Ceftriaxone through intravenous route for 3 days prior to collection of samples. From this study, it may be concluded that Escherichia coli, Kelbsiella spp. and Citrobacter spp. may be commonly present in enteric fever suspected patients or they may produce enteric fever like symptoms in human.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16857 Progress.

Authors: Rashid MA , Kawsar MH , Rashid MA , Miah MY , Howlider MAR
Published: November 2013

Five hundred ten duck eggs of Pekin and each of Muscovy duck eggs were incubated to determine fertility and hatchability. The eggs were cleaned and stored at 18-21oC for 6 days prior to setting in the incubator. The eggs were incubated in a forced-draft electric incubator and the hatching performances were recorded. Ninety Pekin and ninety Muscovy day-old ducklings were randomly selected from the hatched ducklings for a growth trial. Each breed was divided into three replications and each replication had 30 ducklings. They were reared up to 10 weeks of age. Fertility of Muscovy duck eggs tended to be higher (P>0.05) than that of Pekin duck eggs. Hatchability of Pekin egg on fertile egg was higher (P<0.05) than that of Muscovy eggs. But, dead in shell of Muscovy duckling was higher (P<0.05) than that of Pekin duckling. Feed consumption was higher (P<0.01) in Muscovy ducklings than that of Pekin ducklings. Feed conversion was slightly higher (P>0.05) in Muscovy ducklings than that of Pekin. At 10 weeks of age, Muscovy ducklings were slightly heavier (P>0.05) than that of Pekin. It was concluded that the fertility of Pekin and Muscovy ducks are more or less similar while hatchability is higher in Pekin ducks. Muscovy ducks are superior in respect of feed conversion and growth rate.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16859 Progress. Agric. 20(1 & 2): 93  98, 2009

Authors: Hossain MS , Sarder MRI
Published: November 2013

A series of experiments were conducted to develop and standardize the protocols for cryopreservation of sperm of silver carp (Hypophthalmicthys molitrix) with the view to conserve gene pool. Three extenders such as Alsevers solution, urea egg-yolk, egg-yolk citrate, and three cryoprotectants namely DMSO, methanol and ethanol were employed. Cryodiluents were prepared by mixing the cryoprotectants at 10% concentration of the extenders (%v/v). Milt and cryodiluents were mixed at a ratio of 1:9 for Alsevers solution and 1:4 for urea egg-yolk and egg-yolk citrate solutions. Alsevers solution, urea egg-yolk and egg-yolk citrate with DMSO found suitable for cryopreservation of sperm and it produced 81 ± 2.24%, 79 ± 5.48% and 74 ± 4.18% post-thawed spermatozoan motility respectively. In optimizing milt dilution, five dilution ratios (1 : 2, 1 : 4, 1 : 6, 1 : 9 and 1 : 12) were tested and among them 1:9 (milt: cryodiluent) demonstrated the highest post-thaw spermatozoan motility with Alsevers solution (76.67 ± 2.89%) and 1 : 4 produced the same with urea-egg-yolk (73.33 ± 2.8%) and egg-yolk citrate (76.67 ± 2.89%). As an optimum cryoprotectant fraction, 10% concentration was found effective to produce the highest spermatozoan motility for all three extenders. Sperm preserved with Alsevers solution, urea egg-yolk and egg-yolk citrate plus DMSO demonstrated the ability to fertilize eggs and produced hatchlings.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16861 Progress.

Published: November 2013

An experiment to observe the growth performance of the larvae produced from female Clarias batrachus treated with 4 dietary levels of vitamin E viz. 0 mg, 50 mg, 100 mg, and 200 mg /kg feed was conducted for 28 days. After rearing for 3 months females were used for induction of breeding to produce larvae. Same dose of pituitary gland (100 mg PG/kg body weight) was used for all treatments. From the 7th day of hatching, the larvae were reared for another period of 28 days to see growth and survival rate of the larvae produced by the broods maintained under different dietary levels of vitamin E. In case of growth performance (percent length gain, percent weight gain, specific growth rate) and health condition larvae of T2 (50 mg vitamin E/kg feed) showed significantly better result when compared with those of T1 and T3. There was no significant difference in the growth performance between the larvae of T2 and T4. Larvae of T2 although showed higher survival rate but the difference between different treatments was insignificant. The results concluded that 50 mg vitamin E/kg feed is more suitable to increase growth and survival rate of the larvae.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16862 Progress.
