S M Nazmuz Sakib’s Quantum LSTM Model for Rainfall Forecasting (S M Nazmuz Sakib’s QLSTM-RF)
Authors: Sakib S M Nazmuz
Published: July 2023

: LSTM networks are powerful tools for modeling time series data, as they can capture long-term dependencies and nonlinear relationships in the data. However, they still face some limitations, such as the vanishing gradient problem, the curse of dimensionality, and the computational complexity of hyperparameter optimization. Quantum machine learning algorithms, on the other hand, are emerging as a promising paradigm for enhancing the performance and efficiency of machine learning models, by exploiting the quantum properties of superposition, entanglement, and interference. Quantum machine learning algorithms can potentially offer exponential speedup, lower memory requirements, and higher accuracy than classical machine learning algorithms.Therefore, a hybrid model that combines LSTM networks with quantum machine learning algorithms can potentially overcome the limitations of both approaches and achieve superior results in rainfall forecasting. Specifically, quantum machine learning algorithms can be used to optimize the hyperparameters of the LSTM networks, such as the number of hidden units, the learning rate, the batch size, and the dropout rate. Moreover, quantum machine learning algorithms can be used to enhance the feature extraction and dimensionality reduction processes of the LSTM networks, by using quantum Fourier transforms, quantum principal component analysis, and quantum autoencoders.Additionally, the hybrid model can take into account the effects of solar activity and cosmic rays on cloud formation and precipitation. Solar activity refers to the fluctuations in the sun’s magnetic field, radiation output, and sunspot cycle. Cosmic rays are high-energy particles that originate from outer space and interact with the earth’s atmosphere. Both solar activity and cosmic rays have been shown to influence cloud formation and precipitation by affecting the ionization of aerosols and water droplets in the atmosphere. By incorporating these factors into the hybrid model, it can capture more information from the data and improve its predictive power.

Alpha-2-macroglobulin is differentially expressed in central nervous system metastasis.
Authors: Mamoor Shahan
Published: July 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer and lung cancer (1-3). We mined published microarray and multiplexed gene expression data (4, 5), comparing primary and brain metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the CNS. We found that alpha-2-macroglobulin, encoded by A2M, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. Multiplexed gene expression data (5) revealed conserved differential expression of A2M in CNS metastasis in patients with lung cancer. A2M mRNA was present at decreased quantities in metastasis to the brain in humans with breast cancer. Expression of A2M in primary tumors of the breast was correlated with recurrence-free survival. Modulation of A2M expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with cancer of the lung and breast.
Non-relativistic model of the laws of gravity and electromagnetism, invariant under the change of inertial and non-inertial coordinate systems.
Authors: Poliakovsky Arkady
Published: July 2023

Under the classical non-relativistic consideration of the space-time we propose the modelof the laws of gravity and Electrodynamics, invariant under the galilean transformations andmoreover, under every change of non-inertial cartesian coordinate system. Being in the framesof non-relativistic model of the space-time, we adopt some general ideas of the General Theoryof Relativity, like the assumption of invariance of the most general physical laws in every inertialand non-inertial coordinate system and equivalence of factious forces in non-inertial coordinatesystems and the force of gravity. Moreover, in the frames of our model, we obtain that thelaws of Non-relativistic Quantum Mechanics are also invariant under the change of inertial ornon-inertial cartesian coordinate system.

Exchange Rate Fluctuations and Firm’s Survival: Evidence Manufacturing Contribution to the Nigerian Economic Growth
Authors: Ugwu Chukwuma C. , Okwa Ene I. , Sonia Idemudia
Published: July 2023

Exchange rate fluctuation has remained a challenging issue for developing countries and sub-Saharan African region in particular. Despite all the efforts towards a stable exchange rate by the sub-Saharan African countries in the last decades, economic growth has been sluggish in almost all the countries in the region. Objective of this study is to assess the economic impact of exchange rate fluctuations on manufacturing companies’ survival in Nigeria, taking manufacturing contribution to gross domestic product as a proxy for survival. The study adopted Ex Post Facto Research Design and time-series data was used. Relevant secondary data for this study were generated from Central Bank of Nigeria statistical bulletin and the Annual Abstract of the National Bureau of Statistics between 1990 and 2020. The study employed ordinary least square estimation and used regression analysis to test the relationship between exchange rate fluctuations on manufacturing companies’ survival in Nigeria. The study showed that exchange rate and production growth are positively and significantly related. From the result, exchange rate, interest rate and trade openness are statistically significant at 5 percent level while inflation is not. It therefore shows that exchange rate, interest rate and trade openness have effect on the manufacturing contribution to gross domestic product in Nigeria within the period studied. The indication from the result is that exchange rate fluctuation is not good for a growing economy like Nigeria. Exchange rate as the variable of interest in the study appears with correct sign showing that there is a positive and significant relationship between exchange rate and production growth. Based on the research finding, the study therefore recommends that efforts should be made in order to have an effective monetary policy that will guarantee a realistic exchange rate to boost sectorial output performance in Nigeria.
CXCL9 is differentially expressed in central nervous system metastasis.

Metastasis to the brain occurs in a significant fraction of patients with breast cancer and lung cancer (1-3). We mined published RNA-sequencing and multiplexed gene expression data (4, 5), comparing primary and brain metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the CNS. We found that C-X-C motif chemokine ligand 9, encoded by CXCL9, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. Multiplexed gene expression data (5) revealed conserved differential expression of CXCL9 in CNS metastasis in patients with lung cancer. CXCL9 mRNA was present at decreased quantities in metastasis to the brain in humans with breast cancer. Expression of CXCL9 in primary tumors of the breast was correlated with overall survival. Modulation of CXCL9 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with cancer of the lung and breast.

Published: July 2023

The study investigated the relationship between principals' leadership styles and administrative effectiveness in public senior secondary schools in Oyo State, Nigeria. The role of school principals is crucial in creating an environment that fosters effective teaching and learning, and their leadership styles have a significant impact on the overall functioning and success of the school. A mixed method approach is utilized, combining quantitative surveys and qualitative interviews. Data from 629 principals and 4,204 teachers were analyzed using descriptive statistics and Pearson Product Moment Correlation (PPMC). The study revealed a high level of administrative effectiveness (overall weighted mean = 3.47) among principals in planning (weighted mean = 3.48), coordinating (weighted mean = 3.39), and supervising (weighted mean = 3.47) activities in their schools. However, areas for improvement were identified, such as ensuring the provision of necessary resources, planning for maintenance of school infrastructural facilities, and deciding how the school budget will be spent. The prevalence of autocratic leadership (44.5%) among public secondary school principals in Oyo State was also found, but a significant proportion reported using democratic and digital leadership styles. The findings from the study indicate that there is a significantly high positive relationship (r = 0.958) between leadership styles and administrative effectiveness. The study suggested among others that there is a need for principals to explore alternative leadership styles that promote teamwork, collaboration, and shared decision-making.

Temporal Mechanisms Associated with Affordance in the Perihand Space
Authors: Thomas Tony , Maurya Ankit
Published: July 2023

The space near the body, the peripersonal space (PPS), acts like an anticipatory buffer, giving sufficient time to the motor system to prepare for actions; such as moving towards an object to pick it up, or moving away from a dangerous object in time. The anticipatory mechanisms associated with the PPS involve the pre-activation of motor resources, resulting in visual processing bias that favors the processing of action-relevant properties of an object, such as its distance, size, and manipulability. The anticipatory mechanisms also seem to make more time available for engaging in defensive behaviors. Therefore, it is expected that the subjective experience of time slows down in the PPS. In two experiments, the present project intends to look for temporal distortions in the processing of action-relevant information (manipulability in this case) in the PPS. Experiments 1 (Temporal Bisection task ) and 2 (Verbal Estimation Task ) will compare participant responses between two experimental conditions. The first condition will require participants to place both their hands on the sides of a computer monitor, making the stimuli presented on the monitor appear within the peri-hand space (the 'Near-Hand’ condition). Whereas, the second experimental condition will require the hands to be placed on the lap, making the stimuli appear far away from the hands (‘Far-Hand’ condition). To anticipate the results, there will be temporal overestimation that is specific to manipulable objects, in the PPS. Also, the temporal dilation will be modulated by changes in the Attentional Switch/Gate mechanisms, and not to the Pacemaker component of the Attentional Gate Model of Time perception; reflecting the early anticipatory mechanisms associated with the PPS.

Published: July 2023

This journal aims to establish Papua as the window of Indonesia's spirit for the Melanesian communities. Using a comprehensive qualitative literature review approach, the research analyzes strategies that address geopolitical dynamics, resource competition, cultural and technological impacts, regulatory frameworks, and implementation processes. The article acknowledges challenges in historical grievances, governance, infrastructure, environmental risks, and social cohesion in both Indonesia and Papua. To unlock Papua's well-being and security, several key initiatives are proposed. These initiatives include preserving cultural heritage, improving education and healthcare, developing infrastructure and tourism, promoting regional cooperation, and ensuring equitable benefits for indigenous Papuan communities. Emphasizing drivers of competitiveness such as innovation, research, human capital, and regional integration, the research identifies sectors with growth potential, such as natural resources, agriculture, renewable energy, tourism, and manufacturing. To fulfill Indonesia's global role, an outward-oriented strategy that prioritizes cultural values, economic progress, environmental conservation, maritime collaboration, and diplomatic engagement is recommended. Successful implementation of these strategies is expected to enhance regional stability, increase prosperity, improve cooperation, and achieve inclusive and sustainable development in Papua. The article provides recommendations for strengthening national identity, preserving cultural diversity, empowering local communities, enhancing education, promoting social cohesion, ensuring environmental sustainability, and strengthening global partnerships. By implementing these initiatives, Indonesia can effectively navigate geopolitical dynamics, unlock Papua's economic potential, and foster inclusive growth. This research aligns with the vision of Indonesia Golden 2045, promoting a harmonious, prosperous, and inclusive environment.
On Liking How You Look and Feeling Sexy: Quantifying the Overlap Between Sexual Desirability and Body Satisfaction in a Sample of Australian Sexual Minority Men
Authors: Grey Wesley , Harris Emily , Kalokerinos Elise Katherine , Griffiths Scott
Published: July 2023

The body image field aims to cultivate positive body image. To do so, it must appreciate factors contributing to positive body image. Sexual desirability is one such factor. Using experience sampling data from Australian sexual minority men, we aimed to quantify the overlap between sexual desirability and body satisfaction. We found sexual desirability and body satisfaction correlated strongly between- (r = .90) and within-persons (r¬¬Median = .60). Using dynamic structural equation modeling, we analyzed 238 participants' data (T = 9,058), finding that sexual desirability and body satisfaction were bidirectionally related – previous sexual desirability predicted current body satisfaction (β = 0.22) and vice versa (β = 0.17). Our results suggest prior sexual desirability contributes more to current body satisfaction than prior body satisfaction does to current sexual desirability. We also found participants’ average body satisfaction tended to be higher when sexual desirability contributed more to body satisfaction (r = .31) and was more stable (r = .19) across time. Our results suggest that (1) sexual desirability and its dynamics across time influence body satisfaction considerably, and (2) research on sexual desirability and its relationship with body image should be a focus for the field. We discuss avenues for future research on sexual desirability.
Estimating chronological age from the electrical activity of the brain: how EEG-age can be used as a marker of neural integrity
Authors: James Thomas , Burgess Adrian
Published: July 2023

As the number of older adults around the globe increases, the need to understand age-related changes in the brain, and their effects on cognition, has become increasingly pressing as we seek to make progress in the early detection and treatment of conditions such as dementia. There is extensive literature on the effects of ageing on the EEG, such as a decline in Peak Alpha Frequency (PAF), but here, in a reversal of convention, we used the EEG power-frequency spectrum to estimate chronological age. The motivation for this approach was that an individual’s brain age might act as a marker of their neural integrity, whereby a discrepancy between chronological age and EEG-age could prove clinically informative by implicating deleterious conditions. With a sample of sixty healthy adults, whose ages ranged from 20 to 78 years, and using multivariate methods to analyse the broad EEG spectrum (0.1 to 45 Hz), strong positive correlations between chronological age and EEG-age emerged. Furthermore, EEG-age was a more accurate estimate and accounted for nearly twice as much variance in chronological age as the best PAF-based estimate of age, indicating that EEG-age is a more comprehensive measure of integrity. We conclude that EEG-age could become a biomarker for neural and cognitive integrity.
Cross-Societal Variation in Norm Enforcement Systems: A Review
Authors: Molho Catherine , De Petrillo Francesca , Garfield Zachary H , Sam
Published: July 2023

Across human societies, people are sometimes willing to punish norm violators. Such punishment can take the form of revenge from victims, seemingly altruistic intervention from third parties, or legitimized sanctioning from institutional representatives. Although prior work has documented cross-cultural regularities in norm enforcement, substantial variation exists in the prevalence and forms of punishment across societies. Such cross-societal variation may arise from universal psychological mechanisms responding to different socio-ecological conditions, or from cultural evolutionary processes, resulting in different norm enforcement systems. To date, empirical evidence from comparative studies across diverse societies has remained disconnected, due to a lack of interdisciplinary integration and a prevalent tendency of empirical studies to focus on different underpinnings of variation in norm enforcement. To provide a more complete view of the shared and unique aspects of punishment across societies, we review prior research in anthropology, economics, and psychology, and take a first step towards integrating the plethora of socio-ecological and cultural factors proposed to explain cross-societal variation in norm enforcement. We conclude by discussing how future cross-societal research can use diverse methodologies to illuminate key questions on the domain-specificity of punishment, the diversity of tactics supporting social norms, and their role in processes of norm change.
Ending the Stigma of Male Domestic Violence and Abuse Victims: A Mixed-Methods Study
Authors: Ambrozewicz Paige , Fido Dean , Hammond Courtney
Published: July 2023

One in three victims of domestic violence and abuse (DVA) are male. Males experience great levels of stigma, and as such, research that explores public perceptions of this victim group is needed to reduce barriers to reporting and attract gender-sensitive support. Across two studies, this paper investigates public perceptions of male victims of DVA through a mixed methods approach. In study one, 202 members of the public provided judgements of vignettes depicting a scenario of DVA, which differed as a function of victim sex and whether a ‘justification’ (i.e., infidelity) for DVA was present. After controlling for participant age, sex, and own victimisation, vignettes featuring male victims and victim infidelity were viewed more harshly. In study two, comparative deductive thematic analysis was used to explore qualitative perceptions of male victims of DVA between 5 men who did and 5 men who did not identify as being a victim of DVA. Results indicated a distinct lack of knowledge and awareness surrounding male DVA victims' experiences and the support services available, in addition to doubt in the support services’ and Criminal Justice System’s (CJS) ability to effectively respond to male victims. Taken together, this paper highlights the need for gender sensitive support, in addition to improvements across educational pathways, support services, and the CJS to end the stigmas attached to male DVA victims.

Adolescents’ relationship to social media (SM) use shifted significantly during the COVID-19 lockdown. However, less is known about how adolescents’ social media use behaviors and mood were associated during this time. This study examined objective (passively sensed) SM use—including ‘screen time’ (duration of use) and checking (frequency of opening apps), retrospective daily reports of positive and negative affect during SM use, and general negative mood among adolescents during the COVID-19 lockdown period. Participants included 19 adolescents (Mean age = 15.8; 37% female). Bayesian multilevel models examined whether within person-changes in SM ‘screen time’ and checking were associated with 1) retrospectively reported positive and negative affect while using SM and daily duration of SM use, 2) daily reports of overall negative mood. These relationships were examined both within the same day and prospectively (one day’s SM behaviors predicting next-day mood and vise versa). On the same day, stronger positive or negative mood during SM use were associated with more SM ‘screen time’ (duration) and checking. Prospectively (next-day models), checking SM more frequently than usual was uniquely associated with within-person increases in adolescents’ positive mood when using SM the next day (p < .05), but not negative mood when using SM the next day. However, neither ‘screen time’ nor checking were associated with general negative mood on the same day or next day. These findings support the notion that SM is rewarding by highlighting that higher-than-usual SM checking is associated with within-person increases in positive mood during use. These findings also add to growing evidence that social media may not be directly tied to adolescents’ general mood state.

Published: July 2023

In high-income countries, people with low socio-economic status (SES) engage in less leisure-time physical activity (PA) than those with higher SES. Beyond a materialist account of this difference, the role of motivational precursors of which attitudes are emblematic remain poorly understood. This pre-registered study aimed to examine the associations between SES (i.e., income and educational attainment) and motivational precursors of PA (i.e., explicit and implicit attitudes), and whether gender and age may moderate these relationships. We used data from 970 adults (64% of women; mean age = 33 ± 12 years) from the Attitudes, Identities, and Individual Differences (AIID) study. Results of multiple linear regression analyses showed that participants with the highest level of income (> 150,000$ per year) reported more positive explicit and implicit attitudes towards PA than those with lower income. Exploratory analysis further showed that women reported weaker explicit attitudes towards PA, while both explicit and implicit attitudes towards PA became weaker at older age increases. In contrast, educational attainment was not significantly associated with those attitudes, and there was only mixed evidence for a moderating role of participants’ gender on the pattern of associations. Our findings suggest that both the explicit and implicit attitudes towards PA may be socially patterned. Future studies should examine whether such differences may contribute to explain the unequal levels of PA behaviors across social groups.
A pilot randomised controlled trial comparing the effectiveness of the MaTerre180' participatory tool including a serious game versus an intervention including carbon footprint awareness-raising on behaviours among academia members in France

Published: July 2023

Background. Activities embedded in academic culture (international conferences, field missions) are an important source of greenhouse gas emissions. For this reason, collective efforts still need to be strengthened to lower the carbon footprint of the academic sector. Serious games are often used to promote ecological transition. Nevertheless, most evaluations of their effects either uses qualitative methods or focuses on changes in knowledge and not on behaviour. The main objectives of this study are to 1) Evaluate the feasibility of a control and an experimental behaviour change intervention and, 2) Evaluate the fidelity (the extent to which the implementation of the study corresponds to the original design) of both interventions.Methods. People employed by a French research organisation (N=30) will be randomised to one of the two arms. The experimental arm consists in a 1-hour group discussion for raising awareness about climate change, carrying out a carbon footprint assessment and participating to a serious game called “Ma terre en 180 minutes.” The control arm consists of the same intervention (1h discussion + carbon footprint assessment) but without participating to the serious game. On two occasions over one month, participants will be asked to fill in online surveys about their behaviours, psychological constructs related to behaviour change, sociodemographic and institutional information. For every session of intervention, the facilitators will assess task completion, perceived complexity of the tasks, percentage of completion of online questionnaires, duration of each session and perceived responsiveness of participants. Descriptive statistics will be done to analyse percentages and averages of the different outcomes.Discussion. Ma-terre EVAL pilot study is a 1-month and a half pilot randomised controlled trial aiming to evaluate the feasibility and the fidelity of a 24-month randomised controlled trial aiming to change academic behaviours such as professional mobility by air, daily commuting and digital and material purchases.

In cosmological special relativity theory, we study Maxwell equations, electromagnetic wave equations and functions. In the cosmological special theory of relativity, we study energy?momentum relations, the Klein-Gordon equation and wave functions. If we solve the Klein?Gordon equation, we obtain the Yukawa potential in the cosmological inertial frame. We derive the Schrodinger equation from Klein-Gordon free particle’s wave function in the cosmological special theory of relativity. We derive the uncertainty principle in cosmological quantum mechanics in cosmological special relativity theory. The Dirac equation is a one order wave equation. The wave function is used as a probability amplitude in quantum mechanics. We derive the Dirac equation from the wave function, Type A in the cosmological inertial frame. The Dirac equation satisfies the Klein-Gordon equation in the cosmological inertial frame. We found equations of complex scalar fields and electromagnetic fields on the interaction of complex scalar fields and electromagnetic fields in Klein-Gordon-Maxwell theory from Type A of the wave function and Type B of the expanded distance in the cosmological inertial frame. In the cosmological special theory of relativity, we quantized the Klein-Gordon scalar field. We treat the Lagrangian density and Hamiltonian in a quantized Klein-Gordon scalar field. We address the particle’s force and kinetic energy in the cosmological special theory of relativity. In the expanded universe, we found the gravity field equation and solution. We found the Schwarzschild solution and Kerr-Newman solution in an expanded universe. Hence, we found a new general relativity theory-the Cosmological General Theory of Relativity (CGTR).
ДОСЛІДЖЕННЯ ВІБРАЦІЙНИХ НАПРУЖЕНЬ, ВИКЛИКАНИХ ПОШИРЕННЯМ ПРУЖНИХ КОЛИВАНЬ У КОЛОНІ ШТАНГ

Задача визначення вібраційного напруження у точці підвісу штанг верстата-качалки,  який приводить у рух плунжерний насос ШСНУ, пов’язана з необхідністю розв’язання одновимірного хвильового диференціального рівняння. Точність визначення величини вібраційного напруження залежить як від швидкості руху точки підвісу штанг, так і від пружних переміщень і їх швидкостей перерізів колони штанг у період початкової деформації колони і у момент початку  руху плунжера насоса угору. Все це разом взяте формує початкові умови задачі. Мета даної статті полягає у визначенні вібраційного напруження при врахуванні дійсної нелінійної швидкості точки підвісу штанг і її заміни лінійною швидкістю і послідовно знайдених значеннях швидкостей пружних переміщень перерізів колони штанг у момент початку руху плунжера насоса вгору. При цьому не враховується пружне переміщення нижнього кінця колони штанг вгору під час їх початкової деформації, а пружне переміщення перерізів штанг у момент початку руху плунжера насоса приймається рівним нулю. Спочатку знаходили швидкість точки підвісу штанг у період їх початкової деформації при використанні кінематики кривошипно-коромислового механізму і її заміну лінійною швидкістю. Після цього були отримані швидкості пружних переміщень перерізів штанг у момент початку руху плунжера насоса вгору у результаті розв’язання допоміжних задач (круглий стержень, один кінець якого защемлений, а другий переміщається із вказаними вище швидкостями; в результаті розв’язування цих задач знаходяться швидкості пружних переміщень перерізів стержня). Ці задачі розв’язувалися методом інтегрального перетворення Лапласа. Насамкінець, знаючи швидкості пружних переміщень перерізів колони штанг у початковий момент руху плунжера насоса вгору і приймаючи пружні переміщення перерізів штанг у цей момент рівними нулю, були поставлені крайові задачі з визначення пружних переміщень перерізів колони штанг при русі плунжера насоса вгору. Ці задачі розв’язувалися методом Фур’є. Отримані розв’язки дали можливість одержати вібраційні напруження у точці підвісу штанг. Встановлено, що врахування нелінійності швидкості точки підвісу штанг незначно впливає на величину вібраційного напруження. Але отримані значення вібраційних напружень є наближеними, оскільки при їх визначенні знехтуванено пружним переміщенням нижнього кінця колони штанг під час їх початкової деформації і пружні переміщення перерізів штанг у початковий момент руху плунжера прийнято рівними нулю. Тому додатково виконана математична постановка ще однієї допоміжної задачі, розв’язок якої дасть можливість отримати у подальшому більш точне значення для вібраційного напруження.

Актуальність досліджень зумовлена необхідністю в забезпеченні промисловості вуглеводневою сировиною. На сьогоднішній день, для забезпечення потреб промисловості  та збільшення енергонезалежності України, доцільно проводити розробку родовищ вуглеводнів. Тому виникає потреба в бурінні і освоєнні нових свердловин. Однією з таких є нафтова свердловина 914-Пасічнянська, навколо якої планується будівництво комплексу привишкових споруд з метою її обслуговування. Відповідно до цієї мети слід провести комплекс інженерно-геологічних досліджень та робіт, спрямованих на детальне вивчення геологічних умов території будівництва. Основним завданням роботи є вивчення природних умов майданчика свердловини 914-Пасічнянська із розміщеними на ньому привишковими спорудами, оцінка взаємодії привишкових споруд із навколишнім середовищем, обгрунтування їх інженерного захисту. Об’єктом досліджень є процес взаємодії споруд із грунтовою основою, явища їх можливого просідання та несуча здатність інженерно-геологічних елементів (ІГЕ). Предметом досліджень є інженерно-геологічні умови території. У більш вузькому значенні – це характеристики всіх виділених ІГЕ (їх пористість, літологічний та гранулометричний склад, консистенція та інші параметри, визначені лабораторними та польовими методами), визначення рівня ґрунтових вод, оцінка зсувонебезпечності схилу та прогноз розвитку несприятливих фізико-геологічних процесів. В роботі використовувались аналітичні методи досліджень (аналіз літературних джерел та фондових матеріалів) та експериментальні. До останніх можна віднести такі дослідження, як буріння свердловин з відбором монолітів і проб ґрунту; лабораторні дослідження фізико-механічних властивостей ґрунтів; камеральна обробка матеріалів. Завдяки бурінню свердловин з відбором монолітів і проб ґрунту були отримані: схема розташування свердловин, позначки границь ІГЕ, нашарування грунтів,  зразки грунту для лабораторних досліджень. Лабораторні дослідження фізико-механічних властивостей ґрунтів дозволили нам отримати їх фізико-механічні характеристики, а завдяки камеральній обробці – інженерно-геологічний розріз. Результати, одержані в роботі, рекомендується застосовувати при будівництві привишкових споруд свердловини № 914. Також, ці результати доповнюють знання про геологічну будову даного регіону та Скибової зони складчатої області  Українських Карпат.

На основі результатів проведених досліджень розроблено технології регулювання процесу обводнення продуктивних покладів та видобувних свердловин шляхом нагнітання діоксиду вуглецю поблизу початкового контуру газоносності, які характеризуються високою технологічною ефективністю. Визначено, що підвищення коефіцієнта вилучення природного газу можна досягнути шляхом реалізації технології нагнітання діоксиду вуглецю за тривалості періоду його нагнітання в поклад, яка за батарейного розміщення нагнітальних свердловин на початковому контурі газоносності і видобувних свердловин у центрі покладу становить чотири місяці на сто метрів відстані між нагнітальними та видобувними свердловинами, а у випадку циклічного його нагнітання – за тривалості циклу нагнітання 8 місяців. Для отримання максимальних значень коефіцієнта вилучення природного газу необхідно забезпечити відповідне відношення відстані між нагнітальними свердловинами до відстані між видобувними свердловинами. Відповідно до результатів розрахунків необхідне відношення відстані між нагнітальними свердловинами до відстані між видобувними свердловинами становить 1,29 для однорідного покладу та 0,97 - для неоднорідного покладу. Підвищення коефіцієнта вилучення природного газу шляхом нагнітання діоксиду вуглецю можна забезпечити у випадку обґрунтування раціональних технологічних параметрів експлуатації нагнітальних та видобувних свердловин. Для забезпечення високих коефіцієнтів вуглеводневилучення необхідно забезпечити раціональне відношення темпу нагнітання діоксиду вуглецю до темпу видобутку природного газу на рівні 1,25. Впровадження розроблених технологій підвищення кінцевого вуглеводневилучення родовищ природних газів для водонапірного режиму дозволить суттєво інтенсифікувати процес видобутку вуглеводнів та вийти на світовий рівень вирішення даної проблеми.

Наведено особливості експлуатації газових і газоконденсатних свердловин в умовах обводнення і конденсації з газу важких вуглеводнів. Охарактеризовано аналітичні залежності для визначення мінімально необхідного дебіта газу для винесення рідини з вибою на поверхню, критичної швидкості руху газу на вході в насосно-компресорні труби (НКТ) і відповідного їй критичного дебіта газу, параметра Фруда для газорідинної суміші, модифікованого параметра Фруда для газового і рідинного потоків і зведеного параметра Фруда для газового потоку. Виконано розрахунки наведених критеріальних параметрів для шести обводнених газових і газоконденсатних свердловин з різною геолого-технічною характеристикою на різних родовищах України. Встановлено сферу застосування різних розрахункових методик для оцінювання умов стабільної роботи обводнених газових і газоконденсатних свердловин. Рекомендовано для оцінювання умов стабільної роботи обводнених газових і газоконденсатних свердловин використовувати значення критичного дебіта газу за формулою Тернера, збільшивши його на 10-20 %, і мінімально необхідного дебіта за формулами ВНДігазу і Кондрата Р.М., Петришака В.С. При використанні формули Тернера необхідно мати достовірне значення поверхневого натягу на межі розділу газ-рідина, а формула ВНДігазу не враховує дебіт рідини. Встановлено умови роботи розглянутих шести свердловин: дві свердловини працюють стабільно з повним винесенням рідини з вибою на поверхню, одна свердловина знаходиться на межі припинення природного фонтанування, а на трьох свердловинах потрібно впровадити методи інтенсифікації винесення рідини.

ABSTRACT

In the current attendance recording process, most of it is still done manually by requiring signatures on paper, which can lead to possible fraud. Doing attendance manually takes time to write and also queue. The online presence application is a solution to overcome this, by creating an attendance application it can help the company to record the attendance of apprentice students. With this system, student attendance can be done using a qr code scanner, so it is no longer done manually using paper. The method used in making this application is the waterfall method which includes requirements analysis, design, development, testing, maintenance. From this research, it produces an application that will help apprentice students to take attendance and for the company in managing the attendance recap of apprentice students and can be used as material for consideration for the company in evaluating and taking action to give value to the intern student concerned. For further research, it is hoped that additional features will be more complete to make it easier for the company to record attendance.
