Authors: Aime Randrianantenaina Solohery Mampionona , Premananto Gancar Candra , Rakotoarisoa Sedera 
Published: April 2022

Objective: Based on cognitive-affective-conative theory, this study aims to create an integrated model that investigates the effects of six marketing-mix components (cognitive) on purchase intention (cognitive) in social commerce (SC) via customer's attitude toward SC (affective).
Design/Methods/Approach: An online survey was used to facilitate the collecting data procedure. A structural equation model with partial least squares is employed to analyze valid data from 200 members of the SC store (Coulisses) who have never purchased in SC.
Findings The results from PLS analysis show that only two components of the SC marketing mix (SCMM) have significant effects on customers' attitude toward social commerce (Att.), which is social influence (SI) and SC needs (SCN). Moreover, customers' attitude toward SC value positively influences purchase intention (PI). Another finding from this research was that internet access (IA) could not moderate the relationship between Att. and PI.
Originality: This paper explained the overarching impacts of SCMM components on PI in SC, as mediated by Att. This study enriches the SCMM theory, which is scarcely discussed nowadays despite the rapid development of SC.
Practical/Policy implication: Practical implications are made for new and old online sellers who want to expand their channels. Sellers need to focus on the role of influencers in their trading business. Moreover, sellers should accommodate more product varieties at competitive prices and quality to compete with offline shops' products.

Published: April 2022

Objective: The main objective of this study is to analyze the importance of intellectual abilities in increasing the role of competence and strengthening the performance of lecturers in the management study program at a private university in Surabaya.
Design/Methods/Approach: The study utilizes 200 samples obtained by distributing questionnaires to respondents. The explanatory method makes it possible to measure confirmatory factor analysis and SEM analysis to test the model.
Finding: The results indicate that intellectual ability has a significant effect on lecturer competence and indirect positive effect on performance. However, the indirect effect is less strong than its direct effect on performance. These results indicate that they have a logical, inspirational, creative, and innovative mindset in carrying out the “tri dharma”, such as education, producing scientific papers published in reputable national and international journals, publishing the results of community service, and contributing to other activities. In short, the stronger the professional competence, the higher the successful performance achieved because of the contribution of intellectual ability as an independent domain of lecturers.
Originality: This is the first comprehensive study conducted at the 18 private universities in Indonesia. Therefore, it will be valuable to better understand the intellectual abilities of lecturers and improve the relationship between their performance and competence.
Practical/Policy implication (optional): The success of lecturers in “tri dharma” activities is an important policy for the academic community, that characterized by their success in producing high performance, not only for individual but also for the universities. In addition, the study concludes with a location model that can be used as an important tool by university leaders in conducting their national and international business because this model can also be applied in various sectors other than the higher education sector.

Inorganic Acid Optimizes Remediation of Formation Damage in Carbonate Producer
Authors: Carpenter Chris 
Published: April 2022

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 208185, “Single-Phase Retarded Inorganic Acid Optimizes Remediation of Drilling Formation Damage in High-Temperature Openhole Horizontal Carbonate Producer,” by Ahmed Mohamed Fawzy, Noor Nazri Talib, SPE, and Ruslan Makhiyanov, SPE, ADNOC, et al. The paper has not been peer reviewed.
Emulsified acid is one of the preferred choices among retarded-acid options used in Middle East high-temperature carbonate producers. However, it also brings operational complexities. The recent introduction of a single-phase retarded inorganic acid system (SPRIAS) has enabled stimulation with the same benefits as those of emulsified acids while eliminating its drawbacks. A newly drilled oil producer in one of the largest carbonate fields onshore Middle East was selected for pilot implementation of the SPRIAS. The experience gained with this pilot well confirmed the SPRIAS as a reliable option to replace emulsified acids in the region.
SPRIAS
The SPRIAS has the dissolution capacity of hydrochloric acids (HCl) of similar concentration. It also has a retardation factor equivalent to that of emulsified acid, which allows the creation of wormholes just as deep into the formation. Such a retardation effect was demonstrated through numerous pore-volume-to-breakthrough (PVBT) coreflow experiments at downhole conditions. Fig. 1 shows such a PVBT experiment with 15% HCl, emulsified acid, and a SPRIAS of similar HCl acid concentration on a 1-in.-diameter×6-in.-long, 8-md Indiana limestone core at 250°F. The PVBT of the emulsified acid and SPRIAS are significantly smaller than that of HCl and are statistically similar.
Because it is not an emulsion but a single-phase aqueous fluid, the SPRIAS also has a viscosity within the same order of magnitude as HCl. This allows the SPRIAS to be pumped at higher rates than retarded emulsified acid. For the application discussed in this study, the SPRIAS was selected to improve the stimulation of the tighter part of the wellbore because the retarded-acid system can develop deep wormholes at low injection rates.

AbstractBit hydraulics is an important factor for obtaining proper hole cleaning and optimized drilling rate or rate of penetration (ROP). The drilling engineer and drilling Foreman must be aware about the effect of drilling bit hydraulics on the drilling operation. The knowledge and interpretation of the drilling hydraulics are the keys of acquiring drilling optimization. Understanding the circulating pressure or mud pump pressure that includes pressure loss of surface equipment, pressure loss of drilling string, pressure loss of mud motor, pressure loss of bit and pressure loss of annulus, is so critical.Additionally, a comprehension of hydraulics will help properly to utilize maximum power that is available to drill hole and know the effect on pressure losses. Knowledge from this research will help in modeling drilling bit hydraulics more accurately and therefore optimize rate of penetration. Also, will introduce a new robust rate of penetration model that takes into consideration the effect of drilling bit hydraulics before spud or start drilling hole section. This is the first study to develop such a new methodology and validate for drilling bit hydraulics on rate of penetration in a real time.There are several theoretical methods, and models have been proposed to determine the rate of penetration models that are not applicable in drilling and work-over operations and were not including the influences of drilling rig or bit hydraulics properly. The critical influence to have an optimized rate of penetration is extremely dependent on implementing proper drilling bit hydraulics. Drilling bit hydraulics from same formation section, mud type, rig and bit hydraulics were collected and analyzed to determine their effect on ROP. A strong new model, methodology and strategy were established for optimized bit hydraulics to confirm high drilling rate to reduce the drill time and accelerate wells delivery.Drilling bit hydraulics such as total flow area of nozzles (TFA), jet velocity of nozzles (Vn), pressure loss of bit (dPb), Hydraulic horsepower of bit (HHP), hydraulic horsepower of bit per square inches (HSI), jet impact force (Fj) were considered in this methodology.The methodology confirms optimum well drilling performance that can facilitate to improve the rate of penetration to assist drilling engineers and foremen to reduce the drilling time. Validation of deployment of this model has shown improved rate of penetration by more than 50%.

Abstract
Assessing drilling and rig operations performance are a cumbersome issue for oil operators. The evaluation of effectiveness of drilling operations and safe, environmental and competent manner is drilling scenarios such depths, formation lithology, drilling proximity, directional plan complexity and completion types. In this paper a new a new firm methodology improves rig performance is implemented during drilling operations. The method strongly depends on monitoring drilling time and dead time. Drilling time or rotating time and dead time or non-productive time will assessed during drilling operations to predict the rig performance and hence evaluate which performance of drilling rigs has the highest ratio. The ration is based on the drilling time (Tdrilling) over dead time (Tdead) for evaluating rig efficiency. The methodology can compare performance in different scenarios under variable condition with difficult uncertainties. That will lead to utilize the provided resources by oil operators effectively. Several procedures and tactics were developed earlier to evaluate the rig efficiency regarding drilling rate, hole cleaning and rig operations effectiveness, however, they lack for practicality in fields, not applicable in all drilling scenarios, high cost & time impact. Many offset data for rotating time and non-productive time were collected to analysis and monitor the performance of rigs to come up with best estimate of rig performance indicator (RPI) by using technical limit ratio (TLR). The TLR uses, rate of penetration (ROP), Hole cleaning performance (HCP) and rig matrix to finally develop RPI which is ratio that combines ( rotating time plus lost time during drilling over ( dead time plus lost time during rig operations. RPI contains time drilling, rig operations, coring, tripping, completion, blowout preventer equipment (BOPE) nippileing and wellhead work. This is the first time to develop RPI to utilize and evaluate the performance efficiently in real time and was deployed in filed operations. RPI showed recognized improvement in rig efficiency by 50%. Hence, it ca be run in a real-time operating center (RTOC) for meeting fourth industrial revolution for drilling automations. It an effective tool for drilling team to allow immediate evaluation and monitoring for optimizing rig performance
Circ_0047339 promotes the activation of fibroblasts and affects the development of urethral stricture by targeting the miR-4691-5p/TSP-1 axis
Authors: Ding Ke , Li Daoyuan , Zhang Rui , Zuo Meilin 
Published: April 2022

Abstract
Background
Urethral stricture is related to scar tissue fibrosis, but its pathogenesis is still unclear. This study aims to explore the mechanism of circular RNA (circRNA) in the occurrence and development of urethral stricture.
Methods
CircRNA microarray was employed to analyze circRNA expression profiles between human urethral scar tissue and normal urethral tissue. The first nine circRNA differentially expressed were selected for RT-qPCR detection. Urethral scar fibroblasts were isolated from human urethral scar tissue and cultured in vitro. The cells were transfected with si-circ_0047339, LV-circ_0047339, and miR-4691-5p mimic and their corresponding negative controls. Related gene and protein expression was measured by RT-qPCR, Western Blot and immunofluorescence staining, and the cell function was detected by CCK-8 and EDU assay. The targeting relationship between miR-4691-5p and circ_0047339 or TSP-1 was analyzed by dual-luciferase reporter assay.
Results
The results of circRNA microarray showed that there were 268 differential genes between urethral scar tissue and normal urethral tissue (circRNA expression difference multiple ≥ 2 and p value ≤ 0.05). The enrichment analysis of KEGG (Kyoto encyclopedia of genes and genomes) showed that these circRNAs were significantly correlated with ECM-receptor interaction. The first nine differentially expressed circRNA were selected to predict the circRNA-miRNA network. RT-qPCR results showed that circ_0047339 was upregulated considerably in urethral scar tissue. After silencing circ_0047339, the proliferation of urethral scar cells decreased significantly, and the expression of collagen 1 (COL-1) and α-smooth muscle actin (α-SMA) also reduced. Circ_0047339 as a competing endogenous RNA (ceRNA) could increase the expression of TSP-1 by competitively binding miR-4691-5p. In addition, miR-4691-5p mimic transfection could inhibit the proliferation of urethral scar fibroblasts and the presentation of thrombospondin-1 (TSP-1), α-SMA and COL-1, while circ_0047339 overexpression eliminated this inhibition.
Conclusion
Our results showed that the dysfunctional circ_0047339 might promote the growth and fibrosis of urethral scar fibroblasts through the ceRNA mechanism, thus promoting the development of urethral stricture via miR-4691-5p/TSP-1 axis.

Published: April 2022

Abstract
Background: Chronic hypoxia is prevalent in chronic kidney disease (CKD), and Blood oxygenation level-dependent magnetic resonance imaging (BOLD-MRI) provides noninvasive evaluation of renal oxygenation. This study aimed to explore the correlation of renal oxygenation evaluated by BOLD-MRI with renal function. Methods: 97 non-dialysis patients with stage 1-5 CKD and healthy volunteers (HVs) recruited in the study. Base on their estimated glomerular filtration rate (eGFR), the patients were divided into two groups: the mild to moderate renal injury (MMI) group and severe renal injury (SI) group. We measured cortical and medullary T2* (COT2* and MET2*) values in all participants by BOLD-MRI. Physiological indices were also recorded and compared among three groups. Correlation of T2* values with clinical characteristics were determined. Results: The COT2* values were significantly higher than MET2* values in all participants. The COT2* and MET2* values of three groups were ranked as HV> MMI> SI (p< 0.0001). There were positive correlations between the COT2* values, MET2* values and eGFR, Hemoglobin (r> 0.4, p< 0.01), while the serum creatinine (SCr), blood urea nitrogen (BUN) and serum cystatin C (Cys C) were significantly negatively correlated with the COT2* and MET2* values (r< -0.7, p< 0.0001). The 24-h urinary protein (24-h Upr) shown weak correlation with the COT2* value (rs= -0.2301, p= 0.0265), and no correlation with the MET2* value (p> 0.05). Urinary microprotein, including urinary alpha1-microglobulin (α1-MG), urinary beta2-microglobulin (β2-MG), and urinary retinol binding protein (RBP), was showed strong correlation with COT2* and MET2* values. According to analysis of receiver-operating characteristic (ROC) curve, we obtained the optimal cut-point between HV and MMI were “< 61.17 ms” (sensitivity: 91.23%, specificity: 100%) for COT2* values and “< 35.00 ms” (sensitivity: 77.19%, specificity: 100%) for MET2* values, whereas COT2* values (“< 47.34 ms”; sensitivity: 90.00%, specificity: 92.98%) and MET2* values (“< 25.09 ms”; sensitivity: 97.50%, specificity: 80.70%) between MMI and SI. Conclusion: The decline of renal oxygenation reflected on T2* values, especially in cortex, may be an effective diagnostic-marker for early detection of renal injury in CKD patients.

Abstract
Background
Stroke is a type of circulation dysfunction in some areas of the brain that causes neurologic events. It is one of the main causes of morbidity, mortality and disability around the world. It has various risk factors such as psychosocial stresses. Job strain is one of the main criteria of psychosocial stress. Recent studies have controversial results and conclusions about the association between job strain and acute stroke. Due to the considerable prevalence of stroke in our country and our province and the lack of studies related to occupational stress and acute stroke in our area, in this study we aimed to find out if there is any association between job strain and acute stroke or not.
Findings:
In this study, 301 participants were enrolled. Patients' mean age was 66.93 ± 15.41 years. 49.2% of these patients were male and 50.8% were female. 1.7% of them had night shift jobs and 7% had high strain jobs. 91% of patients had an ischemic stroke and 9% had hemorrhagic stroke. In this study housewives (46.8%), employees (10.6%), farmers (7.9%) and self-employed patients (7.3%) were suffering stroke more frequently.
Conclusions
Based on statistical analysis and mathematical data, no significant association was found between job types, job difficulties, night shifts and stroke as well as two subtypes of stroke. Housewives, employees, farmers and the self-employed patients were suffering acute stroke more frequently.

Abstract
Lipoptena cervi and Lipoptena fortisetosa are hematophagous ectoparasites from the Hippoboscidae family that mainly parasitizes Cervidae. These species may also attack humans and its bites may cause allergenic symptoms. The aim of the study was to determine the role of Lipoptena species as a potential vector and/or reservoir of Borrelia burgdorferi sensu lato and Bartonella spp. pathogens in forested areas of north-eastern Poland. The presence of B. burgdorferi s.l was shown in 16.6% of L. cervi. Bartonella spp. was detected in 53.5% of L. cervi and in 75.7% of L. fortisetosa, respectively. The conducted study confirmed the presence of Bartonella spp. in L. cervi and L. fortisetosa. The first evidence of Borrelia bugdorferii s.l. in winged specimens of L. cervi was shown. The obtained data indicates that deer keds can harbor these pathogens, but further investigations are required to confirm that Lipoptena could be a biological vector of these pathogens.
