Numerical Simulation in Gas Hydrate Formation

/in /by

The formation of gas hydrates is an undesirable process in the natural gas transportation industry, ensuring the blockage of pipelines and especially the reduction of transport flows and the increase of working pressure. That is why it is necessary to simulate the water adsorption processes using chemicals as well as the mathematical simulation of the processes. The article presents data on the simulation stages and especially the behavior of natural gas with water content in main pipelines.

Numerical Simulation of The Operation of Natural Gas Treatment

/in /by

Natural gas will remain a transitional fuel for many years to come. However, the exploitation of deposits also brings water particles associated with them (with a decrease in their pressure). Therefore, drying natural gas becomes a main activity in providing them as an energy source. In this material, we present a numerical model of the behavior of water in the natural gas mixture and provide data on the use of molecular sieves impregnated with alumina, silica gel, activated carbon, and hygroscopic salts.

Parenthetical Clauses and Their Prosodic Boundaries in English

/in /by

This research explores the intonational features of parenthetical clauses in English, focusing on their role within the broader structure of spoken discourse. Parenthetical clauses, though syntactically integrated into a sentence, serve as optional, often explanatory or evaluative elements that interrupt the main syntactic flow. Their presence poses a unique challenge for listeners and speakers alike, as they must be clearly distinguished from core propositional content without disrupting overall discourse coherence.

Grounded in the framework of discourse intonation and prosodic phonology, this study analyzes the ways in which speakers employ intonational cues—such as pitch contour variation, boundary tones, pausing, and tempo changes—to mark the insertion of parentheticals. The analysis is based on a dataset of natural spoken English, including both scripted and spontaneous speech, with acoustic measurements carried out using PRAAT software.

Findings indicate that parenthetical clauses are typically set off from the main clause by a combination of prosodic features, most notably a noticeable pause before and after the clause, a shift in pitch range (often a reset), and in some cases, a slower articulation rate. These features help signal a temporary departure from the main communicative thread and guide listener interpretation. Moreover, the study reveals differences in intonation strategies based on the syntactic type and discourse function of the parenthetical—whether it serves as clarification, hedging, commentary, or citation.

By examining the prosodic marking of parentheticals, this study contributes to a deeper understanding of how spoken English encodes syntactic and pragmatic structures through intonation. The results have practical implications for speech synthesis, language teaching, and discourse analysis, especially in distinguishing core versus peripheral information in spoken communication.

Effect of Drying Temperature and Wilting Period on the Physical and Sensory properties of Indonesian Pondoh Snake Fruit (Salacca zalacca) Powder

/in /by

Snake fruit (Salacca zalacca) is a thorny plant that grows in clusters. The relatively rapid browning process and the phytochemical content in Pondoh variety snake fruit present its potential as a raw material for fruit tea production. This study aimed to determine and identify the optimal combination of the interaction between drying temperature and wilting duration of the fruit flesh powder in the production of snake fruit powder tea on its physical and sensory characteristics. The research was conducted in two stages: the production of Pondoh snake fruit powder through wilting and drying processes, and the testing of physical characteristics including solubility level and powder tea appearance (L, a, b values), as well as sensory properties encompassing taste, aroma, and color. A randomized block design (RBD) with two factors was employed. The first factor was wilting duration (45 minutes, 60 minutes, and 75 minutes), and the second factor was drying temperature (60°C, 70°C, and 80°C). Based on the analysis of physical and sensory characteristics, it was concluded that the influence of wilting duration (45 to 75 minutes) and drying temperature (60°C to 80°C) resulted in generally easily soluble tea powder with solubility levels ranging from 82.45% to 84.03%. Furthermore, the variations in drying temperature (60°C to 80°C) and wilting duration (45 to 75 minutes) did not show a significant effect on the sensory properties, solubility level, lightness (L), redness (a), and yellowness (b). However, the treatment with drying temperatures of 70°C to 80°C and wilting durations of 60 to 75 minutes tended to yield better results. The taste, aroma, and color were generally liked to very liked, particularly in the treatment with a wilting duration of 75 minutes and a drying temperature of 80°C.
