Risk Management in Oil and Gas Field Development Project with Marginal Resources: A Case in Mature Field in East Kalimantan
Authors: Saptarini Dyah A. , Nainggolan Yunieta A. 
Published: September 2022

The oil and gas industry and risks are very related to each other. There are several risks known in this industry, from economic risks, political risks, environmental and safety risks, up to geological risks itself. Because oil and gas are a non-renewable source of energy, the more mature an oil and gas field is, the risks for the company to develop a project investment may be lower and higher at the same time. Entering its declining phase, PT MNO who is trusted to operate an ex-termination oil and gas field in East Kalimantan which has been producing for almost 50 years, is required to find a way to survive until end of contract in 2037 by developing the remaining hydrocarbon resources which become more and more marginal. The project development is proposed as a bundling to allow flexibility during execution phase in selecting the well candidates based on recent data acquired from previous wells drilled, hence reducing the risks. Field Development Package (FDP) 2.3 is prepared as part of PT MNO long term plan and commitment after receiving incentive from Government of Indonesia in 2021. According to the Company Guideline, a risk register is mandatory to be developed since beginning of project which covers risks identification, risks analysis, and risks evaluation. The project team is also responsible to define risks treatment to manage the risks borne by the project. This is in line with the requirement for Good Corporate Governance, where risk management is introduced since beginning of the project life-cycle. This study covers the risk assessment on the basis of selected project scope which has been validated technically. The risk assessment will determine the major risks in FDP 2.3 considering available historical data of oil price, drilling cost realization, and facility cost realization. These risks need to be monitored to ensure the FDP 2.3 will create value for the shareholder as per plan or avoid loss at the minimum. The most important risks concluded in this study is oil price lower than economic assumption, production target not achieved, and no fix gas sales contract to absorb production. The company may focus in these risks for the risk management of future project development.
Regional Science, Location and Economic Theory: Thoughts and Discussions about Development
Authors: Castro Hélder Uzêda 
Published: September 2022

This theoretical discussion intends to reinforce some of the main aspects of Regional Science, discussing the spatial issue through studies on geographic location, and how these relate to important economic theories. From the rescue of the thinking of classic authors of Regional Science, emphasizing spatial and location issues, and of Economics with a focus on development, using the resource of bibliometric research of periods of contemporary history, it was possible to review thoughts and theories and emphasize the importance of connecting factors present in economic and geographical studies. The region and the territory were approached in an attempt to demonstrate them as an environment for important research phenomena. It was noted that phenomena linked to Regional Economic Development have re-emerged in recent years as a global trend, considering internal movements due to the health crisis (COVID-19) and global conflicts (i.e. Russia x Ukraine), but they are still poorly studied. The scientific contribution lies in strengthening the relationship between what is discussed in academia and what happens in society.

Published: September 2022

The use of social media and IT application tools as an alternative pedagogical approach in higher educational institutions of learning cannot be compromised. Considering their incalculable advantages especially, in these times of the COVID-19 pandemic where closure of schools characterised some of the mitigating factors which wedged pedagogy. Nonetheless, quite a few institutions have taken advantage of these technologically inclined resources to facilitate teaching and learning. Therefore, this study explores the perceived usage of social media outlets and IT application tools in the University of Cape Coast (UCC) as a means of pedagogy by the Academic Staff. The study employed a cross-sectional survey as result of which 102 Academic Staff were sampled. The findings disclosed that the use of social media (i.e., Twitter), online collaborative tool (i.e., Google Hangouts) as a means of pedagogy is conspicuously absent among the teaching staff. Whiles some IT application tools (i.e., Dropbox, Google Drive, OneDrive) were hardly used in the classroom context, although the participants revealed possessing the skills in the use of such social media outlets and the IT application tools at their individual level. However, the use of Presentation tools (i.e., Microsoft PowerPoint), Spreadsheets (i.e., Microsoft Excel) and Word Processing (i.e., Microsoft Word) were mostly used to facilitate teaching and learning. The study recommends the adoption and enforcement of these resources by the management of the university. Taking into cognizance, the numerical strength of the yearly enrollment of students into the University vis a viz its limited infrastructure.

Published: September 2022

At least 33 million people worldwide are living with human immunodeficiency virus (HIV) infection, and about 20-30% of these are also infected with hepatitis C virus (HCV). Co-infection with HIV and HCV is a major public health concern. Co-infected persons develop cirrhosis and end-stage liver disease more quickly than individuals infected with HCV only. The particular HCV strain or genotype is a major factor for HCV prognosis. The pattern of HCV genotypes in a cohort of HIV/HCV co-infected patients was investigated. One hundred (100) adult patients were recruited from the Nigerian Institute of Medical Research (NIMR), Yaba, Lagos, with age ranging from 18 to 65 years (58% male). Upon recruitment, they were placed on appropriate antiretroviral drugs; 300 mg tenofovir (TDF), 200 mg emtricitabine (FTC) plus 600 mg efavirenz (EFV) once daily dosage. HCV genotyping was done using the Linear Array hepatitis C virus genotyping kit (Roche Molecular Systems, Inc. USA). HCV genotyping revealed prevalence of genotypes 1 (65.6%) and 4 (34.4%), respectively. These are the hard-to-treat genotypes that previously required a long duration of HCV therapy until newer drugs were introduced. The nature of HCV genotypes in HIV/HCV co-infected people has serious implications for further HCV therapy. These findings are pertinent for decisions about the best possible time for and kind of HCV treatment in the setting of co-morbid HIV infection.
Impact of hydrocarbon oxidizing strains Serratia grimesii and Bacillus sp.3 on microcenosis of molluscs and ecosystem components under oil pollution impact

Bivalved molluscs are natural filter feeders of the aquatic environment due to their physiological characteristics. Passing sea water containing emulsified oil through them, they bind its droplets in pseudofeces, thereby accel-erating water self-purification. Mussels prove to be resistant to oil pollution. Experiments have shown that in aquariums with mussels the content of petroleum hydrocarbons decreases faster than in the tanks without mussels. The interaction of mussels with oil has been studied in detail. It has been established that when passing through the body
of mussels the group composition of oil products changes. Oil resignification is noted, which is also observed during its natural weathering. Currently, for the post-purification of natural ecosystems from oil pollution, the method of introducing active hydrocarbon-oxidizing microorganisms is widely used, often with the simultaneous incoming of additional biogenic elements, the so-called bioaugmentation. In this regard, the study of the interaction of oil-oxidizing microorganisms and molluscs is of practical and scientific interest. The aim of the work was to study the interaction
of hydrocarbon-oxidizing microorganisms on molluscs Unio and other components of the microecosystem when modeling the process of oil pollution. A study was made of river water, soil and molluscs Unio from model microecosystems for contamination by saprophytic and hydrocarbon-oxidizing microflora with the additional introduction of hydrocarbon-oxidizing microorganisms – Serratia grimesii and Bacillus sp.3 under conditions of Caspian oil pollution.The values of the bacterial composition of saprophytic and hydrocarbon-oxidizing microflora obtained in the experiment suggest that the processes of restoration and reclamation of a water body take place due to the structural and functional organization of ecosystems and communities.

Abstract in English
Clean drinking water supply is a major concern to the population of the urban municipality of Boké, Republic of Guinea. This study is aimed to investigate the favourable geological structure for the accumulation of groundwater in Boké. Apparent resistivity data was collected by using the Schlumberger-type vertical electrical sounding technique. The apparent resistivity values were obtained on a bi-logarithmic scale in which the distances AB/2 were plotted on the abscissa and the resistivities are on the ordinate. It found the number of terrains and their characteristics (resistivity and thickness) in the area and the behaviour of the current in the soil through a curve. The results show that the structures favourable to the accumulation of groundwater were fractured dolerites, cracked shales and cracked or crushed sandstones. The sandstones were the most important in terms of the amount of water. They are located at a depth of more than 100 metres. It was also found that dolerites and shales are located at shallower depths (less than 100 m).

Easy Risk Assessment for Unmanned Aircraft Systems: Outline of the Method
Authors: Wyszywacz Wiktor 
Published: September 2022

Abstract
The key element of safety systems in air transport is risk management. The rules for the safety of unmanned aircraft system (UAS) operations are established by the Commission Implementing regulations (European Union [EU]) and national regulations. Risk assessment is the foundation of all activities. The broadest scope is covered by the special category of flights for which the Joint Authorities for rulemaking on Unmanned Systems (JARUS) developed the Specific Operations risk Assessment (SORA) analysis. The primary purpose of the SORA analysis is to create a comprehensive safety portfolio, which is attached to the National Aviation Authority (NAA) application for permission to perform specific category flights. Aviation authorities may accept the use of other risk analysis methods to demonstrate risk reduced to a safe level. Easy risk Assessment (erA) for UASs is an attempt to determine the risk for UAS flights in a simple way by considering a range of factors influencing risk management in a similar way to the SORA. It is an uncomplicated method, which determines threats and their sources, provides risk management, and allows the determination of the level of risk tolerance. The ERA is intended to be an alternative to the SORA methodology for those looking to carry out risk assessment.
Determination of the Geometric Properties of a Jet Engine Fan Blades Based on Modal Vibration Testing

Published: September 2022

Abstract
The article presents an experimental method of determining the geometric properties of jet engine rotor airfoils based on modal vibration testing. The procedure is based on adjusting the results of analytical calculations to the laboratory outcomes. Experimental tests were carried out on a set of 20 jet engine fan blades made of AL7022-t6 aluminium alloy. Each blade differed in weight and geometric dimensions within the accepted design tolerance. Numerical analysis of five airfoils that differed in thickness was performed. Modal vibration test results were summarised and compared with the results obtained by the numerical method. The comparison revealed a high similarity of the frequency and form of vibrations acquired by numerical simulation for each of the blades in relation to the executed vibration testing. Based on the verification of the theoretical model with the results obtained through experimental testing, conclusions were drawn about the object’s dynamic behaviour and its technological quality and geometric properties, whereby each of airfoil was probably thinned.

Rozważania na temat zrzeczenia się prawa do wniesienia odwołania w kontekście orzecznictwa sądów administracyjnych
Authors: Tyska Magdalena 
Published: September 2022

W niniejszym artykule ukazano prawo do zrzeczenia się wniesienia odwołania od decyzji administracyjnej w wybranych zagadnieniach w świetle orzecznictwa sądów administracyjnych. Instytucja ta została wprowadzona do krajowego porządku prawnego w 2017 r., a powstałe wątpliwości przy jej stosowaniu doprecyzowuje judykatura. Dla jasności podjętych rozważań pierwsza część artykułu przedstawia charakterystykę prawnej konstrukcji zrzeczenia się odwołania. Dalsza część tekstu odnosi się do najnowszego stanowiska Naczelnego Sądu Administracyjnego w zakresie określenia początku biegu terminu na złożenie oświadczenia o zrzeczeniu się prawa do wniesienia odwołania, możliwości cofnięcia oświadczenia o zrzeczeniu się prawa do wniesienia odwołania, sytuacji procesowej pominiętej strony w sytuacji, gdy strony uczestniczące w postępowaniu zrzekły się prawa do wniesienia odwołania. Nadto przez pryzmat orzeczenia Naczelnego Sądu Administracyjnego podkreślono konieczność pouczenia strony o skutkach skorzystania ze zrzeczenia się odwołania przez organ administracyjny. Zakresem badawczym objęto zatem uprawnienie procesowe strony w postępowaniu administracyjnym, z którego może ona skorzystać, aby przyśpieszyć zakończenie postępowania przez otrzymanie ostatecznej i prawomocnej decyzji. Ostatecznym wnioskiem, do jakiego dochodzi autorka, jest to, że uprawnienie strony do zrzeknięcia się wniesienia odwołania może zostać skutecznie zgłoszone przez stronę nawet w dniu fizycznego doręczenia (ogłoszenia) decyzji administracyjnej oraz istnieje możliwość cofnięcia tak złożonego oświadczenia woli.
