- Perspective on Dating the Sumerian Great Flood and Hypothetical
Reconstruction of Events
Authors: Judith Giannini
Abstract: The Sumerian kingship records are divided into two periods: The Mythical period that ends with the Great Flood, and the Dynastic (semi-historical and historical) period that follows. The dating of this Flood is not known in recognizable calendar years. The purpose here is to attempt to identify a likely modern calendar date and a cause precipitating the event. This is done by calibrating (to calendar years) the length of years of reign during the Mythical period, and also during the semi-historical Dynastic period (counting backward from a known historical date) to identify a range of years that most likely encompassed the Flood. That range of dates is used to identify the geophysical event that can be associated with a possible cause for the Flood, which is the basis of validating the Flood myth as being the result of a real event, not merely an ancient story with religious or political purpose. The relation between the Sumerians and Egyptian during this time is discussed.

- An Almost Old Gravitational Theory Solves the Crisis of Physics
Authors: Walter Petry
Abstract: It is well-known that there is a crisis of physics which is stated by several authors. The author of this article has already given a new theory of gravitation in the year 1979 several years ago and totally different from General Relativity (GR). It is a field theory and not geometry. The redshift of galactic objects e.g. galaxies is by the use of this theory a gravitational effect and not a Doppler one as stated by Hubble and as accepted by almost all scientists today. Einstein has already remarked by the use of GR implying that redshift may also be a gravitational effect as also given by the new theory of gravitation and not a Doppler one. This is the reason for the crisis of physics as noted by many scientists. All of my submitted articles use this new theory of gravitation which I published in the death year 1979 of the great physicist Albert Einstein.

- Pollution, Climate Change, and their MPACT in Cardiovascular and
Respiratory Diseases
Authors: Alcibey Alvarado González
Abstract: The effects of climate change and pollution are widespread and rapidly intensifying and are largely driven by greenhouse-gas (GHG) emissions from burning fossil fuels. Global mean temperatures have already increased by 1.1°C since 1900, and given the current policies and actions, a warming of 2.5°C to 2.9°C or more by the end of this century is expected. Most of the change having occurred in the past 50 years. The climate change is happening faster than expected and that the window to act is quickly closing. The severe injuries induced by pollution and climate change affect the morbidity and mortality of the planet and the species that inhabit it. The human species has the tools and knowledge to reduce this injury and safeguard the future of a habitable planet. One of the great stumbling blocks to achieve this end are the political and economic interests of a sector of the same species that has enough power and control to stop the healthy tools that could solve a problem that is planetary. This document concisely discusses climate change and pollution as etiologies of diseases, giving special emphasis to cardiovascular and respiratory diseases, which constitute a significant example of them but are obviously not the only ones.

- Investigating Soil Instability and Subsidence Risks Using an Integrated
ERT and MASW Analysis
Authors: Oboshenure, K. K; George Godwin C, Keme, P.
Abstract: Subsidence is a major structural concern, particularly in deltaic areas with soft, compressible soils. This study looks into the subsurface conditions at Niger Delta University, Amassoma, using a combination of Electrical Resistivity Tomography (ERT), Multichannel Analysis of Surface Waves (MASW), and Standard Penetration Tests. Analysis of five ERT profiles identified three stratigraphic layers having resistivity values that ranged from 0.453 Ωm to 145 Ωm, indicating different soil compositions and moisture levels. MASW measurements also confirmed these findings, with shear wave velocities ranging from 207 m/s in the topmost layer characterised with moisture to 824 m/s in the deepest probed layer. The computed Standard Penetration Test (N-value) findings revealed a significant variance in soil strength, with N-values ranging from 8.3 in the topmost layer to 459 in the deepest layer probed. This complex profile suggests that the softer upper layer, which is insufficiently secure for normal foundations, overlies stiffer layers. The study emphasises the importance of deep foundation techniques and soil stabilisation in reducing subsidence risks and ensuring the structural integrity of facilities. These findings provide critical insights into geotechnical engineering techniques in deltaic regions, emphasising the significance of thorough subsurface investigations in anticipating and dealing with structural stability issues.

- Phytochemical Screening, Antimicrobial Properties and Pharmaceutical
Applications of Tapinanthus globiferus Leaf Extract
Authors: Alang Michael Bong; Ngassoum Martin Benoit, Nodem Sohanang, Fotio Defo Danielle, Njong Vera Akah
Abstract: This study was carried out unveil the secondary metabolites of Tapinanthus globiferus leaves used in traditional medicine through meticulous phytochemical screening. The leaf extracts were obtained by methods of Soxhlet extraction and maceration using water and ethanol as solvents. The leaf extracts were used to carry out phytochemical screening, carry out some antimicrobial susceptibility tests and indicate some industrial applications of the plant extracts. The extract obtained by maceration in 95% ethanol gave a yield of 14.85% and extract tested positive flavonoids and other polyphenolic compounds. For extended qualitative analyses, the following secondary metabolites were identified; tannins, saponins, anthraquinones, reducing sugars, alkaloids and terpenoids. The phenolic compounds present give the extract antioxidant and antimicrobial properties. The antimicrobial susceptibility tests were done on three bacterial species (E. coli with 27.78% inhibition, Staphylococcus aureus 28.33%; Streptococci 23.33%) and a mold (C. albicans with a percentage inhibition of 26.67%). Results from microbiological analysis showed that the plant extracts could inhibit the proliferation of some pathogenic bacterial and fungal species. The minimum inhibitory concentration (MIC) of the plant extract was 15.63 mg/mL for both E. coli, S. aureus, and Streptococcus respectively while the MIC for C. albicans was 125 mg/mL. But the minimum bactericidal concentration (MBC) of the plant extract against the bacteria was 125 mg/mL while the minimum fungicidal concentration (MFC) of the plant extract against C. albicans was 250 mg/mL. The outcome of this research validates the use of this plant in traditional medicine and also validating the plausible application of Tapinanthus globiferus in pharmaceutical and cosmetic preparations for public health enhancement amongst others.

- Development of a Cryptography Secured E-Administration System
Authors: Ohwobeno; Omohwo, Iwasokun, Gabriel Babatunde, Adegoke, Michael Abejide, Agbelusi, Olutola, David, Bamidele, Ibraheem, Temitope
Abstract: This paper presents the design of the e-administration platform that adopts the concept of cryptography for identity management. The architectural framework of the platform comprises subcomponents for service and forms identification, business process redesign, service architecture, amalgamation, and deployment. The cryptography model for securing the platform was designed based on the combination of authentication criteria presented in the Rijndael-Advanced Encryption Standard (AES), Lattice-based cryptography (LBC), and Secure Hash Algorithm (SHA512). It is required that a record be encrypted prior to its commitment to the database via a double encryption method. The AES algorithm-based encryption’s output formed the input to the LBC algorithm to obtain the final output. Five text files of varying sizes were used to evaluate the performance of the AES, GGH, and the Hybrid Encryption Algorithm (HEA). The evaluation of the algorithms focused on three key parameters; namely encryption time, decryption time, and the size of the encrypted file. Results showed that the time taken by the HEA encryption algorithm encryption and decryption processes is significantly higher compared to the time taken by the AES and GGH algorithms. This suggests that the HEA takes longer times and hence will be more difficult for intruders to manipulate or read.

- Enhancing Cancer Registry Data for Comparative Research at the Nairobi
Hospital
Authors: Elvis M. Ondego; Lucy A. Ochieng
Abstract: The global incidence of cancer is rising, with GLOBOCAN projecting over 1.27 million new cases and one million deaths by 2030. This trend underscores the need for robust cancer registries to inform policy, healthcare financing, and resource allocation. High-quality cancer registry data is essential for comparative effectiveness research, which evaluates the efficacy of different treatments and interventions. This study aimed to determine the prevalence and distribution of various cancer types by age and gender among patients at The Nairobi Hospital (TNH). A retrospective cohort review of 362 patient records from TNH was conducted. Data were collected from confirmed cancer cases using ICDO and IARC guidelines and analyzed using CANREG-5 and Excel 2016. Among the 362 cases, 34% were male and 66% were female. Cervical cancer was most prevalent (30%), followed by prostate and breast cancers (13% each). Age-specific data showed the highest cancer prevalence in males aged 60-75 and females aged 45-59. Childhood cancers were less than 2%. The study highlights the importance of enhancing cancer registry data for effective cancer care and policy-making.

- Fractal Representation of Composite Elementary Fermions with Positive and
Negative Mass Components
Authors: Judith Giannini
Abstract: The Fractal Rings And Composite Elementary Particles (FRACEP) Model provides an alternate view to the elementary fermion picture. FRACEP represents a dual universe where there are equal amounts of positive and negative matter (mass). Its dual universe construction allows for composite particles of mixed (positive and negative) mass with fractal-based components. The fractal dimension of these composite particles is D = ~1.55, and is consistent with other estimates of D for the elementary fermions and other fractal-based composite models. Initial efforts developed an empirically-based two-parameter fit for the mass hierarchy formula, relating the fractal dimension to the composite particle masses. The formula predicts the cross-family (first-generation particles) masses, and the intra-family masses (the three generations within each family). The mass predictions for the structure-based composite particles, as well as, the mass hierarchy are consistent with the Particle Data Group’s 2016/2020-update estimates for the elementary fermions.

- Incorporating Flood Inundation to Flood Risk Modeling
Authors: Stephanya Salazar Lotero; Frederick Bloetscher, Mushfiqul Hoque, Wiebo Liu, Daniel E. Meeroff, D. Mitsova, S. Nagarajan, S. Salazar, Hongbo Su, Ramesh Teegavarapu, Zhixiao Xie, Yan Yong, Caiyun Zhang
Abstract: Coastlines are particularly vulnerable to flood under multiple conditions, including heavy precipitation, high sea levels and tropical storm surge. These conditions should be considered to assess and manage inundation with more effectiveness. As a part of a larger research effort to develop a watershed level screening tool to identify areas with potential for flooding, incorporating readily available data on topography, ground, and surface water elevations, tidal data for coastal communities, soils, and rainfall data. However, the most destructive impacts are more likely to be from storm surge – moving waves of water that inundate the coast. While SLOSH and other models can be used for this purpose, this effort reviewed prior storms to determine the impact surge actually has on coastal communities in South Florida. What was found was that in urban areas, a wedge of surge waters could be created. Likewise a wedge could be created for natural areas, although natural area extension was double that of urban areas. The wedge can be added to storm events, acting as inputs for Cascade 2001 software to calculate the headwater height for probabilities of inundation.

- Best Input Factors in EDM 90CrSi Using Graphite Electrodes by TOPSIS
Method
Authors: Le Thi Phuong Thao; Nguyen Thi Quoc Dung, Vu Trung Tuyen
Abstract: This research presents a study that found the ideal process variables for Electrical Discharge Machining (EDM) of 90CrSi using graphite electrodes. This work used a multi-criteria decision making (MCDM) approach for the first time to produce cylindrical-shaped parts utilizing the EDM technique and various kinds of graphite as the electrode material. The MCDM problem was solved using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) approach, and the weights of the criteria were estimated using the Entropy method. Furthermore, the two investigational criteria used were electrode wear rate (EWR) and material removal rate (MRR). Furthermore, five process factors were examined: servo voltage (SV), servo current (IP), pulse on time (Ton), pulse off time (Toff), and graphite type (TOG). In addition, the experiment was designed and the outcomes were assessed using the Taguchi method in Minitab R19 software. Furthermore, for this experiment, the design L18 (6^1 + 3^4) was used. The MCDM issue has been resolved, and the ideal process parameters were recommended.

and Breastfeeding
Authors: Solís-Pacheco Josué; Rodríguez-Arreola Ariana, Julia Aurora Pérez-Montaño, Aguilar-Uscanga Blanca Rosa
Abstract: COVID-19 represented a public health problem for pregnant and breastfeeding women, and the question arose whether or not to continue breastfeeding. Various studies were carried out to elucidate whether or not breast milk from mothers in the COVID-19 pandemic and post-pandemic stages provided benefits to newborns. We collected information on PubMed, Scolar Google, Research Gate platforms about studies carried out on breastfed newborns from mothers infected with COVID-19, during pregnancy and after delivery. We used the scientific reports carried out between 2019 and 2023 show that a mother infected with COVID-19 or vaccinated does not harm the health of the infant, on the contrary, the consumption of human milk provides important immunological and neurological benefits to newborn babies. The results of these studies support vaccination as a useful clinical strategy to beneficially affect anti-SARS-CoV-2 IgG levels in the human milk. The reported research demonstrates that breast milk is safe and effective, even during times of illness in a mother infected with COVID-19, and provides protection to the infant when the mother has been vaccinated against COVID-19.

Authors: Kouamé; Maïmouna Liliane, Zoro, Armel Fabrice, Brou, Gboko Konan Gatien, Traoré, Mariam, Touré, Abdoulaye, Soro, Yadé Réné
Abstract: Knowledge of the physicochemical and nutritional parameters of milk is essential for its use. It is in this context that the present study was conducted with a view to contributing to the food security of the people of Poro by assessing the physicochemical and nutritional quality of raw milk produced by three breeds of cattle from traditional farms in the Korhogo sub-prefecture. A survey was carried out among farmers to describe their treatment of cattle up to milking. Milk samples were taken from pasture by milking three breeds (Métis, Zébu djeli and Goudales). Physicochemical and nutrient parameters were determined using the AFNOR method. The study revealed that 56.38% of the breeders were foreigners and 52.13% had more than 10 years' experience. Traders accounted for 51.06%. Cattle were fed on pasture (100%) and milking was carried out manually (98.93%). The results of the physicochemical and nutritional parameters of the milk analysed are as follows: pH (6.70 - 6.80); acidity (16 - 18 °D); density (1.01 - 1.03); ash (6.16 - 7.90 g/L); lipids (32.20 - 45.10 g/L) and proteins (37.57 - 42.47 g/L). These results show that the milks studied comply with standards and could contribute to food security for the people of Poro.

- Dirac’s Variable Gravitational Parameter G Offers a Link Between
Gravity and Quantum Mechanics
Authors: Jarl-Thure Eriksson
Abstract: The Standard model has successfully depicted the universe from a tremendous number of astronomical observations. However, the model faces several problems, it does not provide theoretical explanations for the origin of the Big Bang, dark energy or dark matter. The theory behind this article, CBU for Continuously Breeding Universe, was developed according to known principles of physics. The universe is an emerging system, which starts from the single fluctuation of a positron-electron pair. Expansion is driven by the emersion of new pairs. The gravitational parameter G is inversely proportional to the Einsteinian curvature radius r. The Planck length and Planck energy WP are dependent of the curvature and accordingly by the size of the universe. As a measure of the change of the state between a stationary body (G0) and a moving body (G1) the ratio G1/G0 unites the Special theory with the General theory of relativity. Relativity means that the motion of a body always is relative to another body according to the ratio of their G values. The introduction of different individual Gs implies symmetry in the twin paradox, leading to the first credible solution to the problem.

Abstract: Our cognitive perception of ׳Paradise׳ usually portrays an attractive heavenly garden, ‘Eden’, where Adam and Eve were created (ref. 1). Quite the opposite is our imaginary picture of ‘Hell’, a concept raised at early Christianity, describing an afterlife world of punishment in flames of those being evil or living in sin during their life time.

Authors: Helli Kitinoja; Kaija Nissinen, Maria Kasanen, Mari Salminen-Tuomaala
Abstract: Aims: The objective of this study was to describe experiences about multiprofessional and cross-sectoral co-operation, its forms, success, and challenges, in promoting the overall health and wellbeing of children, adolescents and their families in the Healthy Kids of Seinäjoki (HKS) action model. Methods: The European Commission Criteria to select best practices in health promotion and chronic disease prevention and management in Europe (2017) was used as a theoretical framework in the current state analysis of the HKS action [1]. Several methods were used in collecting the data: policy documents of the City of Seinäjoki, electronic survey to all the staff members, interviews of the directors and virtual workshops for the key informants. Data collected by the electronic survey was analysed by using the SPSS statistical programme and other data collected by using inductive content analysing. Results: In the policy documents and in directors´ interviews all city sectors were seen as actors in the promotion of health and wellbeing of children, adolescents, and their families, in the survey 68% of the respondents experienced that they co-operate a lot or to some extent with the other sectors. Co-operation with the actors outside city sectors was seen weak. Multiprofessional teamwork, transfer meetings and integrated services were seen as best practices. Challenges were seen to be development of co-operation and information sharing. Conclusions: Coordination of services, multiprofessional teamwork, cross-sectoral comprehensive working methods and holistic thinking are needed to develop in the promotion of health and wellbeing of children, adolescents, and their families.

Brazilian Oil and Gas Industry'
Authors: João Lafraia; Murillo Dias
Abstract: This study examines the impact of organizational power distance, uncertainty avoidance, autonomy, and trust on the capacity to produce desired operational discipline and achieve better ESG results in a Brazilian Oil and Gas Company's business unit. Previous studies highlight the importance of intangible factors in internal coordination for operational discipline. However, a combination of low trust, high power distance, high uncertainty avoidance, and collectivism creates a reactive planning culture, increasing transaction costs and hindering efficiency and effectiveness in solving complex problems. The results show that individualism and uncertainty avoidance predict operational discipline, while power distance and trust moderate the first two variables.

- Harnessing Active Force: the Pumping Mechanism of Child’s Swing
Motion
Authors: Rong Li; Weicheng Cui
Abstract: Life mechanics, an emerging field, focuses on the self-organizing motions manipulated by the mind within living systems. This study introduces the concept of 'active force’, generated by mind-body-environment interactions, as a fundamental driver underlying these self-organizing movements. As an example, we propose a new set of control equations to model the self-pumping swing motion by incorporating the active force into Newton's second law. With this new mechanical framework, we inversely derived the total (i.e., responsive) active force due to the body-environment interaction from the child’s swing motions with rapid standing and squatting movements. It revealed a pulse-like pattern of the total active force along the swing length, driving changes in the radial speed and swing length. This force counteracts the resistance and propels the swing, which is not attainable by the stone. Consequently, the active force serves as the foundational principle for self-organization in living systems, offering a novel mechanical approach for understanding and predicting extraordinary movements (e.g., sports and rehabilitation) regulated by the mind (e.g., nervous system) in biological systems.

Authors: Tersoo-Abiem Evelyn Mnguchivir; Abel Christopher Omale, Akpensuen Mfe Samuel
Abstract: Pawpaw fruit powders were produced from two mature unripe Carica papaya fruit cultivars via sun-drying and oven drying respectively, and were used to stabilize thermized yoghurt, at 0, 1, 2 and 3% concentrations respectively. The pawpaw fruit powders were evaluated for functional, physicochemical and microbial quality. The values for pH, TTA, TSS and moisture content ranged from 5.51±0.01 to 5.71±0.01, 0.11±0.01 to 0.13±0.01, 2.41±0.01 to 2.91±0.01 and 13.35 ±0.21 to 14.90±0.14 respectively. The functional properties of the fruit powders revealed bulk density, water absorption capacity, oil absorption capacity, emulsion capacity and foam capacity values ranged from 0.46±0.01 to 0.76±0.01, 0.81±0.01 to 1.61±0.01, 0.81±0.01 to 2.60±0.01, 4.70±0.07 to 7.95±0.07 and 39.21±0.01 to 48.05±0.07 respectively, while the microbial load of the powders were within acceptable levels. Results of the physicochemical analyses of thermized yoghurt with addition of pawpaw powder at different concentrations for pH, total soluble solids, specific gravity and TTA values ranged from 5.39±0.01 to 5.67±0.02, 11.72±0.03 to 12.61±0.01, 1.00±0.00 to 1.19±0.00 and 0.01±0.00 to 0.21±0.01. The microbial load of the stabilized thermized yoghurt showed no significant bacterial and fungal count. Results of sensory analyses revealed that 1% pawpaw fruit powder addition to thermized yoghurt was the most preferred.

- Implementation of Principal-Agent Relationship: Case Study Strategic
Decision in Financing Policies
Authors: Verawati; Erwin Saraswati, Noval Adib
Abstract: Strategic Decisions in the self-help housing finance assistance policiy create complexity both in the formulation and implementation processes. The failure to achieve the target for distribution of self-help housing financing assistance funds proves that strategic decisions have not accommodated the needs of stakeholders and policy implementation has not been effective. This research aims to describe problems that arise during the process of strategic decision making and it’s implementation and also identify necessary improvements. Using qualitative methods with a case study approach, data collection in this research was carried out using in-depth interviews and documentation studies. The research results show the formation of a principal-agent relationship between the Ministry of PUPR and stakeholders. Conflicts of interest in the strategic decision-making process are very clearly visible when the Ministry of PUPR faces various different goals (goals conflict) between the need for empowering financial and financing institutions, provision of houses that meet construction quality standards, financing schemes and product structures that suit market needs, and easy requirements, while still prioritizing conformity with other laws and regulations and mitigating the risk of utilizing government budget funds. Strategic decisions agreed upon under the influence of these conflicts of interest ultimately provide challenges in the policy implementation stage. In order to minimize agency conflicts that occur, improvements to policy and governance are needed.

- An Innovative Paradigm and Proposal of the Universe Including Gravity,
Magnetic Field, and Magnetic Shielding
Authors: Eiichi Akaho
Abstract: The universe is expanding and is believed to be infinite. Therefore, we should consider the physical nature of the universe as an infinite and endless matter. To begin with the speed of light by Einstein’s theory , in which speed of light is fastest, that theory should be stated on the earth only, or at most in the Galactic system only. Because , somewhere in the universe there might be some object which runs faster than light. The gravity formula on the earth should include the effect of magnetic fields and they should be considered te be the following two types; Akaho’s gravity formula-1 for two mases on the Earth which is F = G (M is the mass of object M, and H is the magnetic value of object M. N is the mass of object N and P is the magnetic value of object N. r is distance between M and N. G is 6.67259 x 10-11m3 .S-2 .kg-1). Akaho’s formula-2 is, F = (M is the mass of the Earth which is 5.973 ×1024 Kg. H is magnetic field of the earth which ranges from 25,000 to 65,000 nanoteslas depending on the location. N is the mass of N. P is the magnetic field of the object N. ) . We don’t have to use G because we used the actual values of mass and magnetic field of the earth.- The universe is expanding constantly, and it is an endless object (or just a mass). Anything can exist and/or happen. For these the present mankind are not aware of them. As far as gravity shielding or antigravity is concerned various projects or proposal have been taking place. Those include creation of antigravity from electromagnetism, transversal suspended accelerometer designed to investigate the effect of gravity shielding, and non-magnet methods of propagation to create thrust. Something intriguing device and/or idea will be developed in the near future.

- Telepathic Proficiency - A Factual Threat on Humanity
Authors: Michael Gurevitz; Roee Dagan
Abstract: The molecular mechanism underlying human cognition is still a ‘black box’ despite intense brain research. The ~1.4 kg brain tissue contains billions of nerve cells (neurons) connected via synaptic junctions that transport electrical and chemical signals toward target regions, while its functioning is associated with activation or inactivation of variable neuronal networks, demonstrating high plasticity. In recent years, imaging techniques enabling visualizatuin of neurons and synapses have been developed, monitoring brain centers that ‘light up’ by external stimuli (e.g., ref 1). Moreover, various non-invasive techniques for real time monitoring of spatio-temporal (position and time) brain activity upon external stimuli (e.g., sensory, cognitive, motor, regulatory) have been developed {e.g., electroencephalography (EEG), position emission tomography (PET), near infrared spectroscopy (NIRS), magnetoencephalography (MEG), and functional magnetic resonance imaging (fMRI) (e.g., ref. 2)}, but despite this impressive repertoire, the processing mechanisms by which activation of certain neuronal networks constitute our consciousness, soul, or abstractive competence (thinking, spiritual perception, inventive productivity, build-up of moral principles, emotions, memories) remain unclear. These open questions are especially puzzling in light of the central role of the brain in controlling our physical and mental abilities and successful mapping of activated structural regions involved in various functions, as well as in light of the enormous progress in other scientific fields such as exploration of marvels in our planet (structure and function of the earth and deep sea, or the protecting atmospheric layers covering our planet, and the enormous variety of life forms); or, the great advances in medicine and prolongation of life expectancy; or, the new findings about deep space and the universe, and the amazing aspirations of reaching to the stars.

Authors: Michael Gurevitz; Roee Dagan
Abstract: The Big Bang theory, first raised in 1931 by the Belgian physicist and catholic priest Georges Lemaître, and supported ever since by most astrophysicists, depicts a 13.8 billion years-old galactic event, wherein an enormous quantity of light energy that aggregated within an infinitely hot and dense ‘Singularity’ dot, suddently inflated and stretched, spreading tremendous amounts of heat and gas that were the primordial components of the universe. Over time that began at the inflation moment (A. Einstein), the extremely hot matter cooled enough to form galaxies (stars surrounded by planets in orbits dictated by their gravitational interactions). Amazingly, subsequent to the inflationary moment, the universe continues to expand in an accelerating manner.

- Phase Change Material for Thermal Comfort Improvement in Tropical Climate
of Cameroon
Authors: Aloys Martial Ekoe A Akata; Auguste Oscar Mackpayen, Nembot Ouembe Kennedy, Mbiake Robert
Abstract: Current typical dwellings in the Sub-Saharan tropical climate of Cameroon provide opportunities for more effective design and the use of Phase-change materials (PCM) to reduce cooling energy demand. In this paper, a typical residential house of a single family is modelled with the local construction habits and materials under the tropical region of Cameroon. Energy analysis of the building is performed, taking into account the use of PCM paraffin RT26 in order to enhance the thermal comfort of the building. The impact of using phase change material on indoor air temperature is quantified. The results of the numerical analysis obtained show that the PCM can be a good option in a hot climate for reducing indoor air temperature. The average annual indoor air temperature was reduced from 35°C to 25°C.

- The Influence of COVID-19 Infection on Chinese Peoples’ Negative Mood:
The Role of Rumination and Social Support
Authors: Ling-ling He; Zhao Feng, Chun-Mei Hu, Qi-lan Pan
Abstract: Objective: To investigate the Influence of COVID-19 infection on Chinese peoples’ negative mood and the role of rumination and social support, so as to provide reference for the prevention and control of COVID-19 infection. Study design:Cross-sectional study. Methods: Using convenient sampling, 2200 people participated to complete a questionnaire survey. Results: The peoples’ infection rate of COVID-19 was 91.3%, and 89.7% people were infected once. COVID-19 infection could predict peoples’ negative mood positively. Rumination played a partial mediating role between COVID-19 infection and negative mood. Social support not only moderated the predictive effect of COVID-19 infection on rumination, but also moderated the predictive effect of rumination on negative mood. Conclusion: High levels of social support can reduce the impact of COVID-19 infection on rumination and the impact of rumination on negative mood. The whole society should support people in coping with COVID-19 infection in multiple ways, and this can reduce their rumination and negative mood.

- Light Time Delay and Bending of Photon Sources Located in The Solar System
Calculated with The Extended Newtonian Inertia (ENI)
Authors: Barbaro Q Leyva
Abstract: An equation for the gravitational redshift was obtained which coincides with the GR result for the case of an emitter being far from the gravitational field. The expression was obtained from the relativistic Einstein-Doppler effect without using general relativity. This suggested the equivalence between a change of speed and a change of gravitational potential and triggered a generalization of the 2 nd law of Newton using high order derivative of the gravitational/inertial acceleration. The implied gravitational time dilation (considering a variable speed of light) was used in the ENI model previously developed by the author to calculate the Shapiro delay for light sources coming from the solar system. The obtained results agree very well with the results of general relativity (maximum relative deviation of about 0.2 percent for Pluto). The use of the time dilation factor in the Newtonian model yields also results very close to GR. Therefore the factor of 2 commonly attributed to the difference between the Newtonian and the GR model did not appear here. The speed of light for photons grazing the Sun (Earth and the Milky Way) was calculated to be almost the one in vacuum but for a neutron star it is about 30 percent higher than the one in vacuum. The ENI model yielded results consistent with the GR models when applied to the Mariner 6 and 7 missions, and to the Cassini probe. The ENI model for the deflection of light was extended (without invoking the time dilation) to finite distances of the source and the observer with results being in very good agreement with GR. The decomposition of the starlight frequencies when approaching the Sun was hypothesized

- The Role of Meteorology in The Mining Chain in Northern Brazil
Authors: Douglas Silva Ferreira; Ana Paula Paes, Cláudia Wanzeler da Costa, Renata Tedeschi, Renato Silva Júnior, Wilson Nascimento Júnior, Antônio Nogueira Neto, Paulo Kuhn, Vânia Franco, Edmir Jesus, Pedro Walfir Souza-Filho, Everaldo de Souza, Giordani Sodré, Fabrício Silva, Ivan Saraiva, Eduardo Carvalho, Rafael Rocha, Ronnie Alves
Abstract: Mining is an important branch of the economy in Brazil. Particularly in the eastern Amazon, a large part of the mineral chain spans regions with heterogeneous landscapes characterized by ridges colonized by native rainforests and canga vegetation, where mining activities have developed, rolling hills with extensive pastures and croplands, and restricted urban areas. Regarding operational activities, the mining industry takes place in open-pit, railway and port settings, all of which are naturally exposed to the impacts of adverse weather conditions. This article addressed the importance of meteorological studies in minimizing and managing the rebounding of atmospheric processes in the mining chain from the mines to the ports. The main methods used in the analyzed studies included regional numerical models and statistical modeling adapted for the target area. The results presented herein refer to the development of climate projections focusing on precipitation extremes, seasonal precipitation forecasts, a short-term meteorological forecasting system, a lightning alert system for mining areas and the creation of a hydrometeorological monitoring network. Such results were presented to stakeholders, who can use information derived from scientific research, especially when planning their respective activities on different time scales, including annual, monthly, daily and hourly timescales, from the perspective of process optimization, human safety, community well-being, biodiversity conservation and water resource management.
