Abstract
BackgroundSurgical education evolves through time, and it's related to the number and type of procedures that residents are exposed to. Hour regulations in resident training affect learning curves, and recording surgical exposure remains to be an effective method to assess and keep track of surgical training. Web-based logbooks have proven to be useful to monitor and follow surgical training in general surgery residents. This study aims to evaluate surgical proficiency in general surgery residents by quantifying their operative exposure and experience by using data collected in a web-based logbook.MethodsA retrospective study from a prospectively collected data base between September 2018 to September 2019 was performed. All surgery residents were surveyed.ResultsA total of 13160 surgical procedures were performed by residents. Laparoscopic cholecystectomy was the most frequent procedure performed 7404 times (52,6%), followed by open appendectomy in 34,6%. Trauma context procedures represent 4.9% of surgical training in our program. Complex procedures such as whipple or distal pancreatectomy represent less than 1% of the training. 70% of residents are confident to perform the surgical procedures proposed for their year of residency, 90% agree that logbooks have a positive impact in their formation.ConclusionWeb based logbooks are a feasible method to follow operative experience in general surgery residents, with adequate record of procedures, its complexity, and trauma context. General surgery residents in our program are confident to perform surgical procedures based on the year of residency. Nevertheless, there is no consensus regarding the best way to measure resident experience and meanwhile we keep relying on proxies.

Oil and gas industry is an international scale of business which is very affected with the global issue and situation. Indonesia is a country that known for its wealth of natural resources especially in oil and gas resources. Production-Sharing Contract is the form cooperation types of contractual arrangements for petroleum exploration and development in Indonesia. With current oil and gas business situation, where oil prices are fluctuative, oil lifting is decreased, operating expenditure of a company tends to increase. The trend of contractor’s net shares on this oil and gas company in Indonesia is fluctuative, it seems very unpredictable pattern. If its continuing, it can obstruct the company’s sustainability and growth. In order to know the significance factor and to optimize the contractors net share of this unpredictable pattern during time limitation to the end of contract then it raises the need to quantify, model and know the significant factors that is affecting the performance of Production Sharing Contract’s net share. Thus can be done based on historical financial data report. The data obtained is used to measure the relationship of independent variables such as operating expenditure, oil lifting and Indonesia crude price to the dependent variable: contractor’s net share in order having a base of decision making to determine the action plan for the PSC by using multiple regressions as its methods. The result showed that oil liftings and Indonesia crude price significantly affect the contractor’s net share.

Authors: Susanto Antoni , Tirok Junius 
Published: November 2021

This paper is to investigate the determinants of the Dividend Payout Ratio (DPR) of Indonesian firms. Five factors (maturity, cash availability, leverage, profitability, firm size) are analyzed as the DPR determinants. Additionally, this thesis also examines the ability of DPR to serve as a signal subsequent year’s earnings growth. Multiple regression models is used in this paper to analyze research sample that consists of 180 firms that are listed in Indonesia Stock Exchange (IDX) and paid dividends during 2003-2008. The results shows that cash availability and maturity are significant determinants of DPR. Further analysis shows that the DPR signals subsequent earnings growth, the result concludes that mature firms has high dividend payment ratio, which supports firm lifecycle theory. High DPR results in high subsequent earnings growth, which supports Black’s (1976) claim that DPR carries information on future growth.
Seasonal effects of controlled drainage on field water balance and groundwater levels

Published: November 2021

Abstract
Adaptive water management solutions such as controlled drainage have raised interest in Nordic areas due to climate variability. It is not fully known how controlled drainage affects seasonal field water balance or can help in preventing water scarcity during dry growing seasons (GSs). The objective was to simulate the effects of controlled drainage on field hydrology using a well-tested, process-based hydrological model. The FLUSH model was calibrated and validated to an experimental field. The model performance with non-local input data was moderate but acceptable for running the controlled drainage scenarios to test the response of the water management method to meteorological forcing. Simulation results showed that controlled drainage reduced drain discharge while increasing surface layer runoff and shallow groundwater outflow. Groundwater depths from the scenario simulations demonstrated that controlled drainage could keep the depth closer to the soil surface, but the effect diminished during the dry conditions. Controlled drainage can be used to change the water flow pathways but has a secondary effect compared with the primary meteorological drivers. The field data set and FLUSH formed a novel computational platform to study the impacts of different water management options on the whole water balance and spatial variability of groundwater depths.
Effect of nozzle geometry on the dynamics and mixing of self-similar turbulent jets
Authors: Nejatipour Pourya , Khorsandi Babak 
Published: November 2021

Abstract
The effect of nozzle geometry on the dynamics and mixing of turbulent jets is experimentally investigated. The jets with a Reynolds number of 13,000 were issued from four different pipes with circular, elliptical, square and triangular cross sections. The velocity field was measured in the self-similar region of the jets using an acoustic Doppler velocimeter. Statistical parameters, such as the mean velocities, velocity variances, spreading rates, mass flow rates, and entrainment rates are presented. The results show that despite having approximately similar decay rates for the mean centerline velocities, the radial profiles of the axial mean velocity varied in jets with different nozzle cross sections and were widest for elliptical jets and narrowest for the triangular ones. On the other hand, velocity variances were greatest for the triangular jet when compared to the jets released from cross sections of other geometries. Furthermore, the spreading rate, mass flow rate, and entrainment rate were highest for the elliptical jet, and lowest for the triangular jet. From this it can be inferred that the elliptical jet has the highest mixing and dilution. The results of this study could help to improve the initial mixing of pollutants by optimizing the initial conditions.

Published: November 2021

Background:
Chronic infection with hepatitis C virus (HCV) is among the major
causes of hepatic fibrosis, cirrhosis, as well as hepatocellular carcinoma (HCC), and it
is associated with a significant risk of developing lymphoproliferative disorders. The rate
of clinical disease progression is variable depending on multiple host and viral factors, including
immune response.

Methods:
To perform a comprehensive epitope mapping of anti-HCV antibodies in patients
suffering from HCV-related liver or lymphoproliferative diseases, we analyzed clinical
samples on a peptide microarray platform made of 5952 overlapping 15-mer synthetic
peptides derived from the whole HCV proteome. We evaluated the antibody profile of 71
HCV-positive patients diagnosed with HCC, mixed cryoglobulinemia (MC), and HCV
chronic infection. Antibody reactivity against virus peptides was detected in all HCVpositive
patients. Importantly, the signal amplitude varied significantly within and between
diverse patient groups.

Results:
Antibody reactivity against C peptides were found generally low in HCV chronically
infected asymptomatic subjects and increasingly high in HCC and MC patients.
Moreover, we found a statistically significant higher IgG response in HCC and MC patients
against specific domains of HCV C, E2, NS3, NS4A, NS4B, NS5A, and p7 compared
to HCV-positive subjects.

Conclusion:
In conclusion, our data suggest that immune response against specific HCV
protein domains may represent useful biomarkers of disease progression among HCVpositive
patients and suggest that peptide microarrays are good tools for the screening of
immunotherapy targets in preclinical HCV research.
