The concept is to create a game based on augmented reality and use object tracking as the primary function for recognizing objects using a camera. The key goal is to design an atmosphere that not only satisfies a person's desire to play video games but also lowers their stress levels in a manner that is both cost-effective and makes less use of flashy devices and cutting-edge technology. The environment produced in this way will use a camera that can identify objects and carry out a series of activities that have been preset according to their functions.

Business Intelligence (BI) plays an important role in decision support systems by analyzing business data. Demand forecasting is a primary part of a sales decision system. In this research work, a Neural Network based Business Intelligence (NNBI) dashboard is proposed for a sales decision system. Data is collected from a leading clothing brand, then NNBI executes data and uses Recurrent Neural Network (RNN) to predict daily, monthly and weekly sales. The accuracy of the prediction model (0.95) validates the performance of NNBI. Tableau, a well-known BI tool is used to design NNBI dashboard. A combination of graphs, charts and text is used to interactively present the sales information. Results of NNBI show that a BI dashboard with the analysis and prediction power of NN is a good fit for a business organization.
THE METHOD OF POTENTIALLY DANGEROUS OBJECTS DETERMINATION, INVOLVED INTO POLLUTANTS EMISSION INTO RIVER BED
Authors:   State University of Telecommunications, Gertsiuk M.M.
Published: June 2023

Abstract. This article describes a method of determination potentially dangerous objects, that could be involved in pollution based on the specified riverbed monitoring point. A way to solve the problem is considered through the filtration and sorting potentially dangerous objects list algorithm, which applies facts database, that allows to determine a possible rived bed potentially dangerous objects list. There are a number on software models and methods, which allows to determine an approximate or exact rived pollutant spill point in case of determining dangerous and/or rising pollutant concentration level from below downstream. Such methods work by forecasting the situation, or direct analysis of the natural environment. These methods make it possible to find the point of toxic substances spillage on the riverbed. However, it is not possible to find the enterprise/factory that made such an emission. Such problem mostly solved using analytical way. A method, which allows to determine a possible list of riverbed pollution potentially dangerous objects has been developed. Current development validation is a series of test checks and simulations that show the correctness of the neural network. A practical realization is implementation of the river pollution forecasting system in emergency situations informational system, to make a functionality, that determines a possible polluting object list based on the selected point of release of hazardous substances. Method can also be used with methods that allow to determine an approximate or exact rived pollutant spill point to find the enterprise/factory that made such an emission.
Development of method of decoding block codes based on differential evolution procedure
Authors:   National Aviation University, Kozlovsʹkyy V. V.
Published: June 2023

The approach of soft decoding of block codes based on determining the most reliable basis of the generator matrix and applying the differential evolution procedure is proposed. The choice of this search optimization procedure was made as a result of the analysis of the features and limitations of evolutionary optimization procedures. The scheme and the essence of the main stages of the developed method of soft decoding of block codes are presented. At the first stage, a hard decision is formed and the received word syndrome is calculated. After that, the received symbols are ranked by reliability and the generator matrix of the block code is transformed into the corresponding most reliable basis. Next, a differential evolution procedure is applied to search for the most probable transmitted information message and a binary codeword. Decoding is completed by inverse transformation of the found most probable binary codeword by rearranging the corresponding elements. It is shown that the key stage of decoding is the search for the transmitted codeword using the differential evolution procedure, and the formation of the most reliable basis of the generator matrix of block code makes it possible to increase the decoding efficiency. In order to be able to technically implement this decoding method, an appropriate algorithm has been developed and its main steps are given. The results of the work can be used for the implementation of new generation radio communication technologies to improve the reliability of the transmission of service messages. It is also recommended to use the obtained results when solving the problem of decoding other error-correcting code structures that are used in modern telecommunication technologies.

The aim of this study was to synthesize LiFe1-xNixPO4/C with x = 0; 0.05; 0.07; 0.09 using the reflux method assisted by microwave irradiation. The goal was to increase the value of the electronic conductivity and reaction rate of Li+ compounds. The results showed that the method successfully synthesized LiFePO4/C and LiFe1-xNixPO4/C with an orthorhombic crystal structure in the Pnma space group. The optimum reflux-microwave irradiation time was 10 minutes, and increasing moles of Ni doping lead to a decrease in the lattice parameters cell volume. The crystalline size ranged from 21.42–22.62 nm, and the surface of the compound particles was irregular. The compound LiFe0.93Ni0.07PO4/C had the highest conductivity (5.45 × 10-7 S/cm).

Due to their chemical stability, potent antibacterial activity, and comparatively low hazardous profile, inorganic metal oxides may be used as efficient antibacterial. Zinc oxide nanoparticles (ZnO NPs) significantly slow down the growth of various bacteria. This study aimed to determine the effect and interaction of pH, calcination temperature, and pectin (capping agent) on the synthesis and antibacterial activity of ZnO NPs. The synthesis was carried out by the precipitation method. Synthesis optimization using Design Expert software (factorial design) with parameters including yield, particle size, polydispersity index, zeta potential, particle shape, and inhibition zone of bacteria (P.acnes, S.aureus, and S.epidermidis). This study proves that the synthesis of ZnO NPs is influenced by pH, calcination temperature, and pectin. Various characteristics of the synthesized ZnO NPs have different antibacterial activity. The results of Design Expert analysis with 3 g of precursor obtained the optimum combination at pH 8.8, calcination temperature of 600°C, and pectin 0.76%.
INFLUENCE OF Au3+ SWIFT HEAVY ION ON DIELECTRIC, FLUORESCENCE, SCANNING ELECTRON MICROSCOPE, AND NONLINEAR OPTICS: 2-AMINO-5-NITROPYRIDINIUM CHLORIDE (2A5NPCl) SINGLE CRYSTAL

Published: June 2023

The single crystal of 2-amino-5-nitropyridinium chloride (2A5NPCl) was developed using the assembled temperature reduction (ATR) technique and a slow evaporation solution. The crystal was cut for irradiation as it was growing. Cesium sputtering was used to choose a swift heavy ion (SHI) of Au3+ from a source of negative ions (SNICS). Au3+ ions of (1013, 5 x1013, and 1014 ions/cm2 ) different fluence irradiated on the semi-organic samples. A luminescence study reveals that intensity decreased due to the loss of luminescence property of the material, which is caused by swift heavy ions (SHI). The formation of intermediate energy levels which converted the photon into phonon affected the radiative transition. Hence, the peak shifted and the intensity of the peak decreased. More ions were activated with lattice disorders at higher fluences, which boosted the activation of ion interactions. Capacitance increased due to this interaction of ions hence dielectric constant increased as increased the ion fluence 1013 ions/cm2 through 1014 ions/cm2 . When a semi-organic 2-amino-5-nitropyridinium chloride (2A5NPCl) was exposed to high fluence radiation, pores, cracks, and roughness could all be clearly visible in the SEM along with the material's roughness. SHI significantly changed the surface of 2-amino-5-nitropyridinium chloride (2A5NPCl) at higher fluence. When compared to pristine, it was determined that the non-centro symmetric system in 2-amino-5- nitropyridinium chloride (2A5NPCl) was less impacted than in the other derivatives of the 2-amino-5- nitropyridinium families of crystals. Irradiated crystals' nonlinear optical properties were less than pristine; however, they were still higher than reference material KDP.

Published: June 2023

Experimental infrared and laser Raman spectra of 3,4,5-trimethoxyaniline were recorded in the first part of our investigation. Theoretically, using Hartree-Fock and density functional theory, structural properties and vibrational frequencies were estimated. The Hartree-Fock level spectral analysis was conducted using the HF/6-31+G(d,p) and HF/6-311++G(d,p) approaches. The B3LYP/6-31+G(d, p) technique was implemented to accomplish the DFT analysis. Comprehensive details of infrared, Raman intensity, scaled frequencies, reduced masses, and force constants are also presented in this paper. The vibrational experimental and theoretical findings are compared in the final section of our investigation using the 3D Gauss view visualization program. This paper also creates and provides Raman and IR spectra of 3,4,5-trimethoxy aniline using HF and DFT methodology.
SIMULATION OF THE PROCESS OF FILLING POLYSTYRENE FOAM FOUNDRY MOLD WITH THE METAL
Authors:   Khmelnytskyi National University, SAVYTSKYI YURYI
Published: June 2023

Modern approaches to prefabrication production consist in the maximum approximation of the shape and size of the blanks to the finished part, which essentially makes the final part cheaper. One of the methods of precision casting is casting in gasified models, or foam models. The basis is the task of developing a theoretical model of filling a polystyrene foam model with liquid metal. The analysis of the process of filling the mold with a gasified model and the process of filling the mold with a closed sprue system are considered. The analysis of the obtained solutions shows that the movement of the metal has the character of aperiodic oscillations. The speed of metal in quantity is maximum at the initial moment of metal processing in the form and happens as it is filled. The pressure of the steam-gas mixture at the initial moment of time exceeds the pressure of the weak metal in the riser, which provides the possibility of metal ejection from the bowl. At the same time, the pressure in the mold cavity changes little with the increase in gas permeability of the mold, which is explained by the small gap between the melting front of the model and the metal mirror. However, with an increase in gas permeability due to a decrease in back pressure, the speed of the metal in the mold cavity and the path traveled by it increase. The analysis of the system of equations allows predicting the behavior of metal during the design of molds for the summer, which reduces the probability of production defects.

La siguiente investigación exploratoria de tipo mixto (cualitativo y cuantitativo), ilustra el uso y apropiación que se le pueden dar a las redes sociales digitales (RR. SS.) y a las aplicaciones con las mismas características en los Proyectos Educativos de Aula (PEA) entre los estudiantes del grado quinto de la escuela Mariano Ospina Pérez y los jóvenes del Instituto Técnico Marillac del grado décimo de Santa Rosa de Cabal, en la resolución de problemas matemáticos como punto de partida para determinar cuáles son las habilidades que más se pueden apropiar y la forma en que se pueden adquirir, con el fin de poder generar una estrategia para el uso educativo de estas redes, permitiendo un acercamiento de la educación a los intereses y gustos de los estudiantes. Para esto, se realizó un muestreo intencionado con los estudiantes y docentes, se buscó determinar la forma de acceso y de permanencia de los estudiantes en internet, asimismo se buscó identificar el conocimiento que tenían de las diferentes redes, al igual que las posibilidades educativas que se pueden presentar. Por otra parte, se implementaron diferentes estrategias en las tres redes más utilizadas en cada grado, se observaron las diferentes habilidades educativas que los jóvenes pueden adquirir y el modo de apropiación, de acuerdo al tipo de actividades desarrolladas en ellas, tales como: la comunicativa, la tecnológica, la cognitiva, la habilidad para trabajar en equipo y la para resolver problemas, asimismo, para la búsqueda y selección de información. Aunque se logró evidenciar que los miembros del grupo focal tuvieron presente que mediante las diferentes redes sociales se pueden generar procesos de aprendizaje, también estaba claro que la falta de conocimiento por parte de los docentes sobre las innumerables posibilidades y lo atractivos que suelen ser para los estudiantes estos ambientes y escenarios de aprendizaje, permitía generar una posibilidad de ahondar e investigar.
cinco libros de Juan Borchers
Authors: Hornillos Ignacio
Published: June 2023

Una carta de despedida sirve como desencadenante para atisbar el final del Taller de Juan Borchers. El arquitecto y teórico chileno, que da nombre a esta organización, dedicó su tiempo al estudio y a la reflexión crítica sobre las ciencias, las artes y la percepción de la realidad física. Sus últimos años de vida, apoyado por Suárez y Bermejo, los dedicó a trazar un plan para dar difusión a las obras realizadas y a las ideas planteadas a través de 5 libros que supusieran el tratado de la arquitectura del siglo XX que aún no había sido escrito. Este hecho lo hemos localizado en “las libretas del hospital” que Borchers utilizaba con Bermejo para intercambiar información mientras convalecía tras sufrir un infarto en 1971 en París. La radiografía de aquellos últimos años, así como el descubrimiento de este manifiesto inconcluso, busca poner en valor aquellos textos que quedaron sin edición.
Célula Habitacional y la Casa Telemática
Authors: Pierpaoli Barbara
Published: June 2023

El objetivo del ensayo es explorar dos propuestas habitacionales que el arquitecto Ugo La Pietra realiza en 1972 y 1983. Se analizan estos paradigmáticos proyectos en sus respectivos contextos, así como la implementación de las nuevas tecnologías en el espacio. En ambos casos, los aparatos electrónicos interactúan con el cuerpo humano, reconfigurando y resignificando los objetos, los ambientes de la casa y la ciudad, ofreciendo unos resultados espaciales y comportamentales diferentes, que evidencian un giro sustancial en la concepción del diseño del espacio y de los objetos. Los proyectos visionarios, adelantan no solo la llegada de internet en el espacio doméstico y urbano, sino que avanzan la cuestión de las redes sociales como agentes transformadores de los rituales domésticos y del entorno cotidiano construido, aportando consideraciones y cuestiones de reflexión para la actualidad.

Published: June 2023

La cartografía ha sido tradicionalmente una de las operaciones llevadas a cabo desde la posición de poder para convertir una ciudad en un espacio ordenado, es decir, previsible y estable. El objetivo de este texto es desvelar esa intención que se encuentra velada bajo la apariencia de una objetividad científica y que genera que el mapa, que nace de un viaje, pase a condicionar los siguientes. Pero también, que es el caminante quien tiene la última palabra y que, en su desplazamiento, se demuestra que guarda la potestad tanto de acatar como de desbaratar las directrices cartográficas oficiales, así como también puede prescindir de cualquier mapa o bien fabricarse uno personal, honesto en su factura y sin pretensiones de universalidad.
tiempo en la obra de Juan Navarro Baldeweg
Authors: Espuelas Fernando
Published: June 2023

Los artistas siempre transfieren tiempo en sus obras, pero cada uno lo hace de muy distinta forma. Puede ser el tiempo histórico del suceso que reconstruye, o el tiempo fugaz que corresponde al momento del día en que se pintó, o puede reflejar la velocidad con que se realizó el cuadro, o manifestar el tiempo transcurrido desde que se acabó la obra. Formas de tiempo que involucran la memoria o la materia. En cualquier caso, con estas u otras modalidades de tiempo, los artistas expresan algo importante de sus intenciones estéticas. Juan Navarro Baldeweg maneja en su obra cuestiones que implican al tiempo de manera muy personal y persistente.
Este ensayo ha procedido a decantar unas formas de tiempo que permiten apreciar su obra de otra manera. Para ello se vale de la capacidad de las palabras, que agrupadas en “ejércitos móviles de metáforas” (Nietzsche), llegan a expresar la verdad.

Published: June 2023

Kehadiran Perseroan Terbatas sebagai suatu bentuk badan usaha dalam kehidupan sehari-hari tidak lagi dapat diabaikan. Pelaku usaha dalam menjalankan praktik bisnisnya sangat lazim dengan kehadiran Perseroan Terbatas sebagai bentuk badan usaha yang digunakan dalam skala usaha mikro, kecil, menengah, hingga skala besar. Sehingga PT merupakan bentuk badan usaha yang paling sering digunakan saat ini dengan ciri khas berupa pembatasan tanggung jawab di dalamnya.konsep Perseroan Terbatas yang mulanya didirikan dengan prinsip persekutuan modal dan berdasarkan perjanjian, dengan adanya Perseroan Perorangan konsep persekutuan modal dan berdasarkan perjanjian tidak lagi menjadi syarat mutlak pendirian PT karena Perseroan Perorangan hanya dapat didirikan oleh 1 (satu) orang pemegang saham. Sehingga, bentuk badan usaha berupa perseroan perorangan ini merupakan suatu konsep yang baru diterapkan di Indonesia yang tentunya menganut prinsip pemisahan tanggungjawab (separate entity) sebagai ciri khas PT antara perseroan dengan pemegang saham (yang tunggal tersebut). Berbeda dengan Usaha Dagang (selanjutnya disebut UD) yang merupakan salah satu bentuk badan usaha yang didirikan dan dijalankan oleh satu orang saja. berdasarkan pendekatan yuridis maka dapat disimpulkan bahwa stautus badan hukum perseroan perseorangan adalah sah berbadan hukum, karena men\mang sudah diatur keberadaannya dalam UU Cipta kerja yang mana diatur menyatu dengan pengertian perseroan Terbatas itu sendiri. Berdasarkan teori Insitusional dan perkembangan ilmu hukum moderna maka secara teori konsep perseroan perseorangan sesuai dengan teori innstitusional, dalam hal ini pengertioan perseroan menggunakan pendekatan teori perjanjian dan institusional.Pemerintah perlu mensosialisasikan keberadaan konsep perseroan perseorangan ini dalam rangka peningkatan pertumbuhan ekonomi bangsa melalui usaha mikro dan kecil. Namun perlu dilakukan pengaturan khusus terkait perseroan perseorangan.
Doyle’s Two-Stage Approach to Free Will: A Biophysics for Real Choice?
Authors: Edwards Jonathan
Published: June 2023

Robert Doyle has argued that traditional difficulties associated with the concept of free will can be resolved by a two-stage approach, explored by several philosophers and scientists. Possibilities for action can be generated within the brain, more or less randomly, from which an ‘adequately determined’ choice can be made. A similar selective process is well worked out within immune cells, which may provide a useful model. A degree of randomness is pervasive in the physical world but living systems have evolved to both tame and exploit this aspect at the interface between fluid and solid phases. Random and systematically determined processes are used in combination. These cell biological considerations support the plausibility of the two-stage model and may help point to specific mechanisms but may also raise a question about ‘who’ is doing the choosing. Computer modelling may sharpen the focus of that question. It may also highlight a paradox – that ‘freedom’ may only exist as the flipside of limitations or constraints imposed by real world situations.
Operadic categories as a natural environment for Koszul duality
Authors: Batanin Michael , Markl Martin
Published: June 2023

This is the first paper of a series which aims to set up the cornerstones of Koszul duality for operads over operadic categories. To this end we single out additional properties of operadic categories under which the theory of quadratic operads and their Koszulity can be developed, parallel to the traditional one by Ginzburg–Kapranov. We then investigate how these extra properties interact with discrete operadic (op)fibrations, which we use as a powerful tool to construct new operadic categories from old ones. We pay particular attention to the operadic category of graphs, giving a full description of this category (and its variants) as an operadic category, and proving that it satisfies all the additional properties. Our present work provides an answer to a question formulated in Loday's last talk, in 2012: "What encodes types of operads?". In the second and third papers of our series we continue Loday's program by answering his second question: "How to construct Koszul duals to these objects?", and proving Koszulity of some of the most relevant operads.
The Relationship Between Cold Stress Syndrome Mortality And Body Shape in Florida Manatees
Authors:   ,   Andrews University, Chirachevin Purin
Published: June 2023

West Indian manatees (Trichechus manatus latirostris) are tropical and subtropical aquatic mamals that can develop cold stress syndrome (CSS) when subjected to water temperatures below 20'C for prolonge dperiods. This study investigtes the potential impact that cold winter water temperatures in Florida may have on manatee body shape as a selective force to reduce surface-area-to-volume ratio (SA:Vol; i.e. Bergmann's and Allen's Rule). Morphometric measurements collected from state-mandated necropsies (1974-2014) were used to calculate surface area, volume, and mass. We found that manatees that died of CSS on average had significantly greater SA:Vol and less mass compared to those that died of other causes, and that for one unit (0.01) increase in SA:Vol, the odds of succumbing to CSS increases by 34.6%
Families and God-human Interactions in Genesis
Authors:   ,   Andrews University, Flores Josias
Published: June 2023

This study carefully analyzes the themes found in various interactions between God and humans in the book of Genesis, viewing them through the lens of family. The majority of the texts that record direct verbal communication between God and humans reveal that God initiates such encounters in order to develop and define healthy families. Themes found in the God-human interactions parallel previous conclusions in family studies research regarding family rituals. Motivated by insights from the behavioral sciences, this work contributes to the scholarly discussion surrounding families from a theological perspective and also provides practical implications for modern-day families.
An Evaluation of Footwashing as Practiced by the Seventh-day Adventist Church
Authors:   ,   Andrews University, Cortez Hadid
Published: June 2023

My goal in conducting this honors thesis is to find the biblical, theological, and historical reasons for why Seventh-day Adventists perform footwashing and the Lord's Supper in the same ceremony. A more thorough analysis of the scriptural texts depicting footwashing and the Lord's Supper could help us discern whether there is a strong thematic connection that justifies their joining into one ceremony. Additionally, research into the origins of the practice of footwashing within the Early Christian Church and the Early Seventh-day Adventist Church will help us discern whether the way that the Seventh-day Adventist Church performs communion is based on biblical principle or Christian tradition.
A Note on the Onset of Synchronous Egg Laying in a Seabird Behavior Model
Authors:   ,   Andrews University, Gallos Dorothea , Gallos Christiane ,   Andrews University
Published: June 2023

Protection Island, Washington hosts a large colony of Glaucous-winged gulls (Larus glaucescens). These birds are known to exhibit every-other-day egg-laying synchrony in dense areas of the colony in response to egg cannibalism, which is the main source of egg loss. Here we present an equilibrium analysis of a discrete-time animal behavior model for egg laying. We use Jury Conditions to find the stability criteria for the equilibrium as a function of the colony density and show that a 2-cycle bifurcation occurs when the equilibrium loses stability. The 2-cycle pattern in egg laying becomes increasingly synchronous as the colony density increases. We also show that egg-laying synchrony benefits the colony by allowing more eggs to survive cannibalism.
Hollywood Dreams: Postcolonial Nationalism and Gender Oppression in Jessica Hagedorn's Dogeatersp
Authors:   ,   Andrews University, Defino Andrei
Published: June 2023

This paper addresses how gender, sexuality, and resistance affect personal and national identity construction in Dogeaters. This 1990 novel traces the lives of Filipino characters during President Ferdinand Marcos's dictatorial regime--a period that reshaped the Philippines' national identity. Using gender theory and nationhood studies, I highlight how women and queer individuals who challenge masculine norms attempt subversion by creating communities outside of patriarchal constructs but ultimately fail. Specifically, I read Joey Sands's and Daisy Avila's marginality and failure to comply with societal expectations as futile pushbacks against the larger system. Furthermore, their embrace and use of violence as a means of final resistance makes them complicity with their oppressors.
The Effects of the Omega-3 Fatty Acid Decosahexaenoic Acid on Intracellular myo-Inositol Levels and the INO1 Gene Expression in Saccharomyces Cerevisiae
Authors:   ,   Andrews University, Ok Taejun
Published: June 2023

Bipolar disorder is a mental disorder portrayed with repeated episodes of mania and depression. Its current treatments often entail inefficacy and negative side effects. From previous clinical research, omega-3-fatty acids were suggested to be effective in the amelioration of bipolar disorder. Such an effect is hypothetically attributed to their ability to alter the level of myo-inositol, a molecule that valproate and lithium are known to deplete out. Thus, the goal of this study is to determine the effects of the omega-3 decosahexaenoic acid (DHA) on myo-inositol levels and the expression of the myo-inositol synthase gene INO1. Yeast cells were cultured with various concentrations of DHA and extracted after 18-24 hours. These cell extracts were enzymatically assayed for myo-inositol concentration and examined by RT-qPCR for gene expression. The results suggest that DHA increases intracellular myo-inositol and decreases the gene expression of INO1, as hypothesized. Thus, the results support the hypothesis that omega 3-fatty acids can ameliorate bipolar disorder by manipulating myo-inositol hypothesis that omega 3-fatty acids can ameliorate bipolar disorder by manipulating myo-inositol level.

Bipolar disorder is a mental disorder associated with abnormal inositol levels. Preliminary studies show omega-3 fatty acids alter intracellular inositol levels; however, the cellular mechanism behind this process is unknown. Therefore, the focus of this study is to determine the effects of the omega-3 fatty acid docosahexaenoic acid (DHA) on the expression of INM1 which encodes inositol monophosphatase. Using yeast as our model system, cells were grown in varying concentrations DHA and the expression on INM1 was determined by RT-qPCR. The results show INM1 expression increased with increasing concentrations of DHA; thus, the effects of DHA on inositol levels may be exerted via its impact on INM1 expression.

The primary objectives of this interdisciplinary study were the synthesis of novel heterocyclic arylidenes and the investigation of their anticancer activity against U87 glioblastoma cell viability. Recently, novel hybrid derivatives have been considered as potential candidates for treating glioblastoma, demonstrating a synergistic anticancer effect in previous studies. 12 heterocyclic arylidenes with various functional groups, including halogens and boronic acid, were produced via a Knoevenagel condensation. These compounds and their starting reagents were then administered to U87 glioblastoma cancer cells at graded concentrations within a 12-well cell viability assay to determine each compound’s lethal concentration 50 (LC50). The LC50 of each compound was then compared to determine the effects of substituent type and position on anticancer activity. Although these arylidenes displayed some anticancer effects, their high LC50 suggest they have no significant effect on U87 glioblastoma cell viability and proliferation.
Is Natural Selection Shaping Florida Manatees? : An Investigation into the Body Shapes Between the Subspecies of the West Indian Manatee
Authors:   ,   Andrews University, Johnson Juliane
Published: June 2023

The West Indian manatee (Trichechus manatus) is currently divided into two subspecies: the Antillean (T. m. manatus) and Florida manatee (T. m. latirostris). Florida manatees are found at the northern extreme of the species range, primarily inhabiting the waters around the Florida peninsula, while the Antillean manatee inhabits the remaining range from the Caribbean islands to eastern Brazil. Only in the range of the Florida manatee does water temperature drop below 20°C during the winter, and these manatees have to seek warm water refuge for thermal regulation. Allen's rule predicts that in colder climates animals will adapt to have smaller surface area to volume ratios (SA:V). It has been reported that on average, Florida manatees are larger in absolute body size than Antillean manatees. However, no one has explored differences in body shape independent of size between the two subspecies. This study proposes that Florida manatees have stockier body shapes (smaller SA:V) compared to Antillean manatees due to the selective pressure of the colder water. Data on Florida manatee morphometrics (n=543) were obtained from the Florida Fish and Wildlife Commission, while Antillean measurements (n=90) came from live captures in Quintana Roo and Tabasco, Mexico. SA:V was calculated by creating a geometric model of manatee shape using standard morphometric measurements. An ANCOVA on SA:V controlling for total length indicated that the SA:V of Florida manatees was significantly smaller (p=0.004). It appears natural selection has not only increased the total body size of Florida manatees, but also altered the body shape in relation to Antillean manatees. Our results lend further support for Allen's rule and indicate that Florida and Antillean manatees are diverging on separate adaptive trajectories.
Are Florida Manatees (Trichechus Manatus Latirostris) Wearing their Teeth Beyond Functionality? Interspecific and Intraspecific Mesowear in Manatees
Authors:   ,   Andrews University, Woodard Nina
Published: June 2023

Manatees (Trichechus spp.) are herbivorous aquatic mammals found in tropical and subtropical waters. At maturity, they possess only supernumerary molars (SM), with 5-8 in occlusion at each quadrant. Manatees exhibit a dental replacement system in which they shed old teeth anteriorly and erupt new teeth posteriorly. This adaptation is thought to have arisen to deal with abrasive foods. Mesowear (facet development on occlusal surfaces of teeth) increases from posterior (younger) to anterior (older) molars. Tooth functionality is linked to level of mesowear, with increased amounts resulting in decreased food-processing ability. Less functional teeth can result in an increase in feeding time, potentially decreasing fitness. Domning (1982) noted that Florida manatees (T. manatus latirostris) appeared to experience greater levels of mesowear compared to other manatee populations, however, he did not quantify the difference. To address this, we examined museum specimens from all manatee taxa: Florida (n=64), Antillean T. m. manatus (n=49), Amazonian T. inunguis (n=121) and African T. senegalensis (n=4) manatees. Photographs of the dental arcade (upper and lower) were taken and analyzed. Each SM in occlusion was numbered (posterior to anterior) per quadrant and classified into one of five discrete wear categories (level 5, extreme, being considered as non-functional). Total number of teeth (TNTQ) and total number of functional teeth (TNFTQ) per quadrant were counted including missing teeth (evidenced by dental alveoli). Florida manatees had significantly fewer mean TNTQ (H=130.03, p<0.001) than other taxa except Antillean manatees, and fewer mean TNFTQ (H=362.21, p<0.001) than all other manatee taxa. In addition, except for SM1, Florida manatees had greater mean levels of mesowear (SM2-SM6) compared to all other taxa. Florida is not only a marginal habitat for manatees because of seasonally cooler water, but also because of the additional dental burden: it appears they are wearing down their teeth faster than the replacement process.
Finding Optimal Input Parameters for BayesWave
Authors:   ,   Andrews University, Rook Kelsey
Published: June 2023

This project involves data analysis for LIGO with the goal of finding optimal input parameters for the BayesWave analysis pipeline, which is an algorithm for the detection of unmodelled gravitational wave transients. To test the BayesWave pipeline, we add binary black hole gravitational waveforms to LIGO noise, and run BayesWave with different combinations of parameters on the resulting signal data to find the best method of separating gravitational waves from noise and glitches. From the results, we calculate various statistical measures for each parameter combination in order to determine which allows for the most accurate classification of gravitational wave transients.
Natural Law, Literary Accommodation and the Successful Social Justice Movement : Thomas Reid's Natural Law Philosophy and the Abolitionist Writings of Olaudah Equiano and Ottobah Cugoano
Authors:   ,   Andrews University, Miller Patrick
Published: June 2023

I will be discussing natural law and the abolition movement of the 18th century-specifically the works of Olaudah Equiano and Ottobah Cugoano, two freed slaves who were members of an English abolitionist society known as the Sons of Africa- and the role that Scottish philosopher Thomas Reid’s ideas of natural law played in their authorship. Natural law philosophy, based on the idea that observation of the natural world can lead to conclusions about morality, has largely been sidelined in modern conversations about ethics. However, it played an important part in one of the greatest moral struggles of western society- the abolition of slavery- both by producing a coherent set of arguments against the practice and, as I will argue, promoting a method of communication by which those arguments were to be successfully delivered. In this project I will seek to demonstrate how natural law philosophy lead early abolitionists to prioritize a literary style that seeks common ground on a basis of universal human identity.

Objectives: To determine the association between cervical radiculopathy and quality of life (QoL) in patients with cervical spondylosis. Methods: This analytical cross-sectional study was conducted on 273 patients in five hospitals in Lahore within 3 months from April to June 2021. The Spurling test was used to measure cervical radiculopathy. The participants were selected according to the inclusion criteria. The Spurling test was used to measure cervical radiculopathy and its symptoms. The World Health Organization quality of life scale (WHOQoL) was used to evaluate the QoL of patients suffering from cervical spondylosis. Results: Of 273 patients, 42.9% were male and 57.1% female. Their Mean±SD age was 42±11.9 years. Also, 70.3% had positive Spurling test, and 29.7% had negative results. Their Mean±SD physical health score was 11.70±1.74 (out of a total of 20), and their Mean±SD psychological health score was 11.75±1.78 (out of a total of 20). The Mean±SD social relationships score was 11.19±2.98 (out of a total of 20), and their Mean±SD environment health score was 11.13±3.08 out of a total of 20. P indicates a significant difference in the QoL between patients with positive and negative Spurling tests. Patients with negative Spurling tests had higher QoL scores. Greater scores denote a higher QoL Discussion: There is a significant association between cervical radiculopathy and QoL in patients with cervical spondylosis. These results will help us in the future to design educational programs or modify the lifestyle of those patients with cervical radiculopathy. This research concluded that there is a significant difference in the QoL among patients with positive and negative Spurling tests. Patients with negative Spurling tests have higher QoL scores. Hence there is a significant association between diagnosed cervical radiculopathy and QoL.
