Published: February 2021

Introduction: An individual’s overall muscle strength is commonly assessed by a power grip measurement, a reliable indicator of functional capacity and physical condition. The development of muscle parallels the changes of body composition during growth. Aim of this study is to examine the correlationship between hand grip strength and anthropometric.
Methods: This cross-sectional study involved 76 male students of Dhammasavana School, aged between 12 – 16 years old, North Jakarta. Hand grip strength was examined using a digital dynamometer on the dominant side. Statistical analysis was computed using SPSS ver. 15.0 program with Spearman correlations test. Significance was set at p<0.05.
Results: Dominant hand grip strength was found to have significant (p<0.05 - 0.001) positive correlation with height (r=0.612), lower arm muscle-and-bone cross-sectional circumference and area (CSA) (r=0.553 and r=0.553 respectively), hand length (r=0.548), forearm length (r=0.540), age (r=0.520), weight (r=0.416), and forearm girth (r=0.376).
Conclusion: No significant correlation between grip strength and body mass index was found. Positive correlations between the variables mentioned above conclude that the higher the value of the anthropometric measurements, the greater the strength generated in a power grip.

Prediction of Liquid Loading in Gas Condensate and Volatile Oil Wells for Unconventional Reservoirs
Authors: Alsadoun Reem , Al Momen Mohammad , Luo Hongtao 
Published: February 2021

Abstract
All producing wells experience reservoir pressure depletion which will ultimately cause production to cease. However, the accumulation of wellbore liquid known as liquid loading can reduce production at a faster rate bringing forward the end of well life. In theory, there are many works written on liquid loading in unconventional wells however, these assumptions are challenged when implemented in the field. The aim of this paper is to investigate the relationship between empirical and mechanistic methods used to determine liquid loading critical rates for volatile oil and gas condensate wells, improving liquid loading forecast workflow for future wells.
The study was carried on a wide Pressure, Volume, and Temperature (PVT) window with varying compositions ranging from gas condensate to volatile oils. Wells with liquid loading exhibit sharp drops and fluctuations in production. Due to the wide variation in composition however, correlations used must be varied whilst accounting for both composition and horizontal configuration of the well. Using Nodal Analysis methods, Inflow Performance
Relationships (IPR) and Vertical Lift Profile (VLP) curves were created from different correlation models fitted for multiple wells selected for this study to optimize well performance. By combining theoretical analysis and field practices for estimating liquid loading critical rate, the appropriate workflow was determined for the volatile oil and gas condensate wells.
When comparing the critical rate for liquid loading calculated from theoretical methods against actual rates seen in the field, an inconsistency was observed between the two values for several wells. By establishing a relationship between field estimate and theoretical calculations, liquid loading was forecasted with greater certainty for varying PVT windows. When the liquid loading rate is determined earlier on, the production efficiency can be improved by deploying unloading measures, increasing the well’s producing life, and ultimately alleviating economic losses. By investigating, we were able to establish a suitable process to predict liquid loading critical rates for volatile oil and gas condensate wells. This workflow can be utilized by production engineers to arrange for liquid loading mitigation increasing well life and improving well economics.

Символічні коди української культури
Authors: Янковська Жанна 
Published: February 2021

Українська культура, як і культура кожного народу, глибоко символічна. Різними символами пронизане буквально все матеріальне й духовне життя етносу: побут, звичаї, традиції, фольклор. На жаль, деетнізація української культури у ХХ ст. та сьогоднішні глобалізаційні процеси не сприяють розумінню та збереженню давніх символів, якими послуговувалися наші предки. Як наслідок – втрачається міжпоколінний зв’язок, уніфікуються знакові смисли культури, утилітарне переважає над духовним, масові «одноденні» явища, швидко виникаючи й так само швидко зникаючи, змінюючи один одного, поглинають традиційні форми культури, які вже не завжди можемо пояснити. Посібник призначений для викладачів освітніх закладів різного типу й для молоді. Матеріали посібника в НаУОА апробовано під час викладання дисциплін тематичного блоку «Традиційна культура українців», зокрема «Народна художня творчість», «Українська етнологія», «Народно-обрядовий комплекс». Актуальний він також у курсах «Усна народна творчість», «Історія української культури», «Українська література», засвідчуючи інтердисциплінарний підхід до вивчення художніх творів. У тексті посібника авторка зробила спробу поєднати науковий і традиційний погляди на окремі реалії та об’єкти народної культури, декодувати їх символіку. Окремі розділи праці присвячені аналізу символіки хліба, вінка, дороги, воріт, культу предків та ін. Цікавий виклад матеріалу, яскраві приклади зумовлюють доступність видання, кожна із частин якого свого часу була апробована під час виступів на науково-практичних конференціях та у відповідних публікаціях.
