Authors: Dhema Albertha Monika 
Published: June 2023

The tendency of speaking anxiety is the condition of individuals who are uncomfortable and feel anxious so that they cannot compose messages when facing situations in public. However, the fact is that students often experience anxiety about speaking in public. One of the factors a person experiences anxiety when speaking in public is a person's self-confidence and abilities because it is closely related to a person's self-concept. The purpose of this study was to find out whether there is a relationship between self-concept and public speaking anxiety among students at Merdeka University Malang. The study population consisted of 12,104 students at Merdeka University Malang, using a purposive sampling technique with a sample of 270 students. The research instrument used a self-concept scale and a tendency scale of public speaking anxiety with a Likert scale model. Based on the results of hypothesis testing, indicates that self-concept has a significant negative relationship with the tendency of anxiety to speak in public. The higher the self-concept, the lower the tendency of public speaking anxiety among students at the Merdeka University of Malang. Conversely, the lower the self-concept, the higher the tendency of public speaking anxiety among students at the Merdeka University of Malang.KEY WORDS: self concept; anxiety; public speaking anxiety; student ABSTRAKKecenderungan kecemasan berbicara yaitu kondisi individu yang tidak nyaman, merasa cemas sehingga tidak mampu menyusun pesan ketika menghadapi situasi di depan umum.

Authors: Alkan Gürkan , Ulusoy Seyhan , Akgün Mert , Oral Ayhan 
Published: June 2023

Nanofibers loaded with pharmaceutical agents for various medical purposes have become more important in recent years because of their advantages, such as control on release, gas permeability, high surface area, and lightweight matrices. In the present study, polylactic acid (PLA)-gelatin (Gel) nanofibers were successfully loaded with Ibuprofen-Na/Paracetamol (henceforth Ibu-Na and Par, respectively) by electrospinning. The nanofibers were characterized by scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. The Ibu-Na/Par content of the nanofibers was determined by using high-performance liquid chromatography (HPLC). Their antibacterial activities were tested against Enterococcus faecalis ATCC 29212, Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, and Pseudomonas aeruginosa PA01, opportunistic pathogenic bacteria which are frequently associated with infections. Moreover, their antibiofilm activities against P. aeruginosa and E. faecalis were also investigated.
The Ibu-Na-containing nanofibers exhibited antibacterial activity against S. aureus, E. coli, and E. faecalis. The inhibition zone diameters of PLA-Gel-Ibu-Na 300 against E. faecalis, S. aureus, and E. coli were calculated to be 23.0 ± 2.1 mm, 18.0 ± 1.5 mm, and 12.0 ± 1.2 mm, respectively. It was found that PLA-Gel-Ibu-Na 300 and PLA-Gel-Par 300 nanofibers’ capacity to show biofilm formation inhibition originated remarkable effects on P. aeruginosa, which were found to be 48 % and 50.4 %, respectively.
This study indicated that Ibu-Na/Par-loaded nanofibers are promising materials for wound healing applications.
METHOD OF ULTRASONIC PHASE TWO-COORDINATE INFORMATION REGISTRATION FOR AUTOMATED NON-DESTRUCTIVE TESTING SYSTEMS
Authors: Malko Volodymyr , Kuts Yurii , Lysenko Iuliia , Scherbak Leonid 
Published: June 2023

The article is devoted to the issue of improving the coordinate registration of information in means of automated non-destructive testing. Existing systems of non-contact registration of spatial position sensors of non-destructive testing are mostly focused on the use of signal fields of different physical nature, for example, acoustic or optical, which are created around the position of these sensors and amplitude methods of signal processing. These methods do not provide the necessary accuracy of determining the coordinates in the case of using small-aperture sensors of non-destructive testing.
The basis of the proposed technical solution is the trilateration method. The distance between the emitter of ultrasonic vibration, which is structurally connected to the sensor, and the two receivers is determined by the phase method. This method provides increased accuracy in determining the coordinates of the sensor. Eliminating the ambiguity of phase measurements is based on the combination of the multi-frequency method and the numerical system of residual classes. This makes it possible to minimize the probability of incorrect resolution of the ambiguity of the results of phase distance measurements and to ensure high accuracy of coordinate determination (with an absolute error of the order of mm). The idea of the method and the main calculation formulas that make it possible to determine the modules of the numerical system of residual classes and the values of the operating frequencies of ultrasonic oscillations are presented. Matching the discretes for determining the phase shifts of signals with the modules of the numerical system of residual classes at different operating frequencies makes it possible to reduce the resolution of the ambiguity of the results of phase measurements to the task of restoring integers in the positional counting system from their representation by residuals in the numerical system of residual classes. The mechanism of occurrence of gross errors in the recovery of whole numbers is considered. An algorithm for eliminating this error is proposed. In general, the correctness of the algorithm for determining the sensor coordinates is confirmed by the simulation results. The considered method of two-coordinate information registration can be used both in the development of new automated means of non-destructive testing, and for the improvement of existing ones, which involve a manual method of scanning the surface of testing objects.
AUTOMATED NATURAL GAS VOLUME MEASUREMENT SYSTEM
Authors: Pysarets Anna , Horzhyi Ihor 
Published: June 2023

One of the main problems in the gas supply industry remains the insufficient accuracy in determining the volumes of consumed gas. On the one hand, this is due to the use of faulty or outdated measuring equipment in metering stations, and on the other hand, the operating conditions of metering stations do not always meet the requirements of technical documentation. In particular, the absence of automated data collection and processing systems from metering stations complicates, and sometimes prevents, the monitoring of actual natural gas consumption. Therefore, the task of creating automated gas volume measurement complexes remains relevant.
The aim of this work is to substantiate the structure and elements of such a complex.
The article presents a generalized structure of a gas metering station based on an automated measurement complex. One of the key elements of complex, ensuring the quality and accuracy of measurements, is the gas flow converter under working conditions.
The authors have analyzed the methods of gas flow measurement that have gained the widest popularity in measurement practice and the possibilities of using devices based on them, considering the peculiarities of the operational use of the complex. In turn, the operating conditions are determined by internal technological, external mechanical, and design factors.
A separate issue in the creation of an automated complex is the application of interfaces for data exchange with other systems or remote data transmission. The paper formulates requirements for the functionality of the electronic computing unit and its software, which, in addition to polling, registration, indication, and calculations, include self-diagnostics.
The application of the complex will significantly improve the quality of natural gas metering and contribute to increased resource utilization efficiency, gas consumption forecasting, loss reduction, prevention of possible emergency situations, and more, based on the collection, processing, and analysis of measurement data.

Published: June 2023

Fit-for-purpose land administration (FFPLA) seeks to simplify cadastral mapping via lowering the costs and time associated with conventional surveying methods. The approach can be applied to both initial establishment and on-going maintenance of system. In Ethiopia, cadastral maintenance remains an on-going challenge, especially in rapidly urbanizing peri-urban areas, where farmers&#039; land rights and tenure security are often jeopardized. Automatic Feature Extraction (AFE) is an emerging FFPLA approach, proposed as an alternative for mapping and updating cadastral boundaries. This study explores the role of the AFE approach for updating cadastral boundaries in the vibrant peri-urban areas of Addis Ababa. Open-source software solutions are utilized to assess the (semi-) automatic extraction of cadastral boundaries from orthophotos (segmentation), designation of &#039;boundary&#039; and &#039;non-boundary&#039; outlines (classification), and delimitation of cadastral boundaries (interactive delineation). Both qualitative and quantitative assessments of the achieved results (validation) are undertaken. A high-resolution orthophoto of the study area and a reference cadastral boundary shape file are used, respectively, for extracting the parcel boundaries and validating the interactive delineation results. Qualitative (visual) assessment verified the completed extraction of newly constructed cadastral boundaries in the study area, although non-boundary outlines such as footpaths and artefacts are also retrieved. For the buffer overlay analysis, the interactively delineated boundary lines and the reference cadastre were buffered within the spatial accuracy limits for urban and rural cadasters. As a result, the quantitative assessment delivered 52% correctness and 32% completeness for a buffer width of 0.4m and 0.6m, respectively, for the interactively delineated and reference boundaries. The study further demonstrated the potentially significant role AFE could assist in delivering fast, affordable, and reliable cadastral mapping. Further investigation, based on user input and expertise evaluation, could help to improve the approach and apply it to a real-world setting.

Published: June 2023

Cows are one of the farm animals that are very popular with farmers. In the villages many people have cattle in their homes. Likewise with the Wono Asri 3 Farmer Group which also has several members who choose to become cattle breeders. Raising cattle is indeed very profitable, but farmers need to have skills and understanding in order to get these benefits. One of the things that needs to be considered in raising cows is feed. Cattle farmers have various types, including some who like to give forage feed (such as grass, weeds, and corn weevils) only, and some like to mix it with concentrate feed. Forage feed is relatively cheaper, but it requires more effort in providing it, while concentrate feed is easier to provide but the price is more expensive. This then affects the farmer's expenditure on feed preparations. Therefore, there is a need for new innovations so that farmers can provide feed at a lower price, but it is easy to provide and of course the quality of the products produced. The activities offered from this PkM are mentoring, and training on processing Corn Weevil and elephant grass (pennisetum purpureum) for members of the Wono Asri 3 Farmer Group. This activity aims to equip the knowledge and skills of processing Corn Weevil and elephant grass into quality animal feed. This activity will be carried out using various appropriate implementation methods such as deliberation, brainstorming, interviews, demonstrations and practices. The planned stages of activities are coordination of teams and partners, identification of target group learning needs including farm conditions and corn weevil processing equipment needed, planning activities involving target groups, training, and mentoring.

RUNX1::RUNX1T1 is a core-binding factor driving fusion gene which arises from t(8;21)(q22;q22). It is one of the most common chromosomal rearrangements in both pediatric and adult Acute Myeloid Leukemia (AML) with a reported incidence of 15% in children and young adults. There are few case reports documenting RUNX1::RUNX1T1 translocation in pediatric AML. Although this is generally associated with a favorable prognosis, we report two (2) cases of de novo pediatric AML in the Philippines harboring a RUNX1::RUNX1T1 translocation, one eventually relapsed while the other attained remission but succumbed to sepsis.
Location, Location—Tanzania, Mozambique Soon To Join Club of Global LNG Suppliers to India, China, Southeast Asia
Authors: Szymczak Pat Davis 
Published: June 2023

_
East Africa is positioning itself as a global player in liquefied natural gas (LNG) with the world’s supermajors staking out projects that will ramp up this decade to supply India, Southeast Asia, and China through 2050.
With three LNG megaprojects—two in Mozambique and one in neighboring Tanzania—soon to take off after years of false starts and delays, it is no wonder that India’s External Affairs Minister Subrahmanyam Jaishankar visited the region in April with energy security top of mind.
Jaishankar’s East Africa trip was the first official visit to the region by an Indian foreign minister in over a decade. He stopped first in Uganda where oil is in play after Uganda inked a deal in February to complete the long-delayed East African Crude Oil Pipeline (EACOP) and deliver first oil in 2025 from Uganda’s Lake Albert oil fields to Tanzania’s port of Tanga on the Indian Ocean.
After spending 3 days in Uganda, Jaishankar traveled to Mozambique where state-owned ONGC Videsh leads an Indian consortium holding a 30% stake in the country’s $20-billion Offshore Area 1 project, Mozambique LNG, which stalled in April 2021 after the operator, TotalEnergies, declared force majeure over terrorist attacks in Cabo Delgado Province near the Afungi peninsula plant site.
Mozambique LNG’s 13.1-mtpa capacity, two-train facility is one of two megaprojects that will help transform East Africa into a global LNG supplier. The other is ExxonMobil’s Rovuma LNG project, another two-train facility for which a final investment decision (FID) was delayed as the Islamic insurgency that had been building since 2020 intensified along the Cabo Delgado coast.
India imports 85% of its oil and 55% of its natural gas. In 2022, it consumed about 22 mpta of LNG, according to Shell’s LNG Outlook 2023. India’s business daily Mint reported that during Q1 2023, India’s LNG imports were worth $14.88 billion, an amount that was 36.46% higher than the $10.90 billion value of LNG India imported in Q1 2022.
So far in 2023, Qatar has been India’s No. 1 LNG supplier followed by the UAE and the US. By 2030, Mozambique, Tanzania, and possibly the Republic of Djibouti (with access to the Indian Ocean via the Gulf of Aden) will be joining the list.
Considering that tankers can deliver LNG and oil from the East African coast to the subcontinent in 3 days, it’s no wonder that Mint described the foreign minister’s visit as “signifying New Delhi’s push to develop Africa as a key (energy) supplier.”

India and China Claim Big Stakes in Future East African Energy Flows
Indian partners ONGC Videsh Rovuma, Beas Rovuma Energy Mozambique, and BPRL Ventures Mozambique control 30% of the Mozambique LNG project (10% each). Total E&P Mozambique Area 1 holds a 26.5% operator interest with remaining shares distributed among Mozambique state-owned ENH Rovuma Área Um (15%); Japan’s Mitsui E&P Mozambique Area 1 (20%), and Thailand’s PTTEP Mozambique Area 1 (8.5%).
Expandable Geopolymers Improve Zonal Isolation and Plugging
Authors: Carpenter Chris 
Published: June 2023

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 212493, “Expandable Geopolymers for Improved Zonal Isolation and Plugging,” by Foster D. Gomado, SPE, Mahmoud Khalifeh, SPE, and Jan A. Aasen, SPE, University of Stavanger. The paper has not been peer reviewed.

_
The sealability performance of an expanding geopolymer (E-GP) is compared with that of an expansive commercial cement (EC) with regard to shear bond strength (SBS) and hydraulic bond strength (HBS) at curing conditions of 25°C and 34.5 bar. A neat Class G (NG) cement and a neat geopolymer (N-GP) were characterized alongside corresponding expansive versions. The effect of these expansive agents on cement and geopolymers was evaluated in terms of linear expansion using the annular ring test. The complete paper reveals that geopolymers can be deployed as an alternative to Portland cement upon optimization.

Geopolymer Characteristics and Use
In recent years, geopolymers have been receiving attention as a viable and environmentally friendly alternative for zonal isolation and plugging and abandonment (P&A) operations because of their robust features such as higher strength, lower permeability, and durability in high-pressure/high-temperature conditions. Geopolymers can be described as binders formed by a chemical reaction between aluminosilicate materials and alkali hydroxide or soluble silicates. In this study, cement/casing bonding properties are the primary focus.
Greener options for cementing, zonal isolation, and P&A must meet acceptable criteria before mass adoption. Geopolymers, like Portland cement, experience shrinkage to some extent. To improve cement bonding, expansive agents are regarded as relevant additives, correlating volume changes to bonding properties, mostly SBS. In the case of geopolymers, few studies have been directed toward the study of volumetric changes with and without expansive additives. The current literature for geopolymers lacks correlation between the performance of expansive agents on geopolymers in terms of HBS, SBS, and load-to-displacement profile.
Thus, the authors explored the effect of expansive agents on SBS and accompanying interfacial friction and hydraulic sealability for both NG and EC, as well as neat geopolymers and expansive versions at equal conditions.

Experimental Procedures
NG cement was used as a reference because it is the most widely used cement in the Norwegian North Sea. The EC was made by the addition of a commercially available expansive agent [made of a blend of calcium oxide (CaO) and quartz] to NG at a concentration of 5% by weight of cement (BWOC). The geopolymer deployed in this study was synthesized in house. The E-GP was synthesized by the addition of a calcium salt in a concentration of 1.1% of the solid precursors.
The complete paper details slurry preparation and the methodology for linear-expansion (shrinkage) tests, SBS/bond slip tests, and HBS tests.

Abstract
Linear secular resonances happen when there is a commensurability between the precession frequency of the pericenter, g, or longitude of the node, s, of an asteroid and a planet. Non-linear resonances are higherorder combinations of these frequencies. Here, we studied the three most diffusive g−type non-linear secular resonances using Artificial Neural Networks. We identified a population of more than 2100 resonant objects in the g − 2g6 + g5 and g − 3g6 + 2g5 resonances. This allows the creation of a Convolutional Neural Network model for the g − 2g6 + g5 resonance, able to predict the status of several thousands of asteroids in seconds. We identified 12 new possible dynamical groups among the resonant population, including the 5507 and 170776 families, which have both estimated ages of less than 7 My. These are the two first-ever identified young families in resonant configurations of the investigated resonances, which allows setting limits on their original ejection velocity field.
