Published: January 2024

Crimes caused by the development and progress of Information Technology and Telecommunications are crimes related to the internet, or in foreign terms it is often called cybercrime. Cybercrime is a crime that takes advantage of technological developments, especially the internet. The internet, which presents cyberspace with its virtual reality, offers various hopes and conveniences, but behind that, problems arise in the form of a crime called cybercrime, both the computer network system itself and the computer itself which is the vehicle for committing crimes. There are a variety of digital scams such as phishing, lottery scams, video scams, identity theft and scareware. This study uses a normative juridical approach. The normative juridical approach is legal research carried out by examining literature or secondary data as the basic material to be examined by conducting a search of regulations and literature related to the problem under study. The efforts of the police in handling fraud cases online are guided by the Criminal Procedure Code (KUHAP) as well as in the Regulation of the Indonesian National Police Number 6 of 2019), namely as "Investigators and Investigators". The step taken by the Police is to trace the accounts used by the perpetrators of crimes, where the last whereabouts or position of the perpetrators of these crimes are.

Published: January 2024

This article is motivated by the law in a study said to be a practical science whose position is certainly special because the pattern as a normative science has its own characteristics in a science. While Economics in history was first assessed as a concrete positive science developed very advanced, without skepticism contributed to a breakthrough in the development of the economy of the people, nation and state.. This article uses a descriptive qualitative approach that is more specific to the data library or library research. In this paper the authors produce that the economy in the context of society is used as a subject of principal as a means to achieve prosperity, because prosperity is a basic entity in humans to meet their needs both goods and services. Then the law is used as the basic instructions, orders, and prohibitions that regulate Order in the composition of society and must be obeyed by those concerned. Furthermore, law and economics were born due to the rapid economic growth in society which causes law to be oriented as an intermediary that limits economic activities in the event of a dispute, which aims at economic progress not to harm the parties either in the rights or interests of the community itself.

Pregnancy is a physiologically demanding phase marked by profound changes that elevate oxidative stress levels, posing potential risks to maternal and fetal health. Oxidative stress, resulting from an imbalance between reactive oxygen species (ROS) production and antioxidant defense mechanisms, has been implicated in various pregnancy complications. Antioxidants, renowned for their ability to counteract ROS and mitigate cellular damage, have emerged as a potential intervention to ameliorate adverse outcomes during pregnancy. The paper highlights the physiological changes in pregnancy that contribute to heightened oxidative stress, emphasizing the link between oxidative stress and complications such as pre-eclampsia, gestational diabetes, preterm birth, and intrauterine growth restriction. This paper emphasizes the imperative for robust, well-designed clinical trials to elucidate the optimal timing, dosages, and formulations of antioxidants in pregnancy. It calls for a comprehensive approach to establish clear guidelines and recommendations for antioxidant supplementation. In conclusion, this review underscores the potential of antioxidants as a promising intervention to mitigate oxidative stress-related pregnancy complications. However, the inconclusive nature of current evidence necessitates further rigorous research endeavors. Through this exploration, it accentuates the urgency for standardized protocols, ethical considerations, and extensive clinical studies to unlock the full potential of antioxidants in improving maternal and fetal health outcomes during pregnancy.

Deep learning-based distributed denial of service detection system in the cloud network
Authors: DENİZ Emine , SERTTAŞ Soydan
Published: January 2024

Cloud computing offers an efficient solution that enables businesses and users to deliver flexible and scalable services by sharing resources. However, this shared resource pool also exposes vulnerabilities to various cyber threats, such as Distributed Denial of Service (DDoS) attacks. These DDoS attacks, due to their potential impact, can be highly destructive and disruptive. They render servers unable to serve users, leading to system crashes. Moreover, they can severely tarnish the reputation of organizations and result in significant financial losses. Consequently, DDoS attacks are among the most critical threats faced by institutions and organizations.
The primary objective of this study is to identify and detect DDoS attacks within cloud computing environments. Given the challenges associated with acquiring a cloud-based dataset, the main motivation behind this research was to construct a dataset within a cloud-based system and subsequently evaluate the intrusion detection capabilities of deep learning (DL) algorithms using this dataset. Initially, an HTTP flood attack was executed after creating a network topology within the OpenStack framework. The study employed Convolutional Neural Network (CNN), Artificial Neural Network (ANN), and Long Short-Term Memory (LSTM) models for attack detection. The performance of these models was assessed using various measurement metrics, and it was found that the LSTM model delivered the most impressive results, achieving an accuracy rate of 98%.
Positioning analysis of the lift force sensor in subsonic wind tunnel test chamber design and its effect on naca0015 airfoil
Authors: TUNCA Samet Giray , ÖZGÜR Mustafa Arif
Published: January 2024

In this study, analysis was carried out by placing the force sensor in different positions in the subsonic wind tunnel test room. NACA0015 profile was used as the airfoil. The model used in the open system subsonic wind tunnel with a 50x50 cm test chamber was manufactured by 3D printing method. Lift force (CL) measurements were studied at Reynolds number (Re) values of 60000, 80000 and 100000. Measurements were analyzed in one-degree increments of the angle of attack, starting from 00. The force device is positioned in 4 different ways around the test room. Efficient results could not be obtained in 3 of the connection attempts. The reason why the results are not efficient is that the fasteners are incompatible with the airfoil, force device and system. The incompatibility of the fasteners caused vibration and a negative situation in the airfoil. There is a slope in the connection made from the side. As a result of the slope, the airfoil has deteriorated.
It was observed that the measurements made by positioning the force device inside the test chamber were compatible with the literature. The resulting graph shows an approach to the literature. Although it is graphically compatible, it should be noted that there is a deviation of approximately 10% in the data. Connection stiffness is gaining importance. It has been observed that stall begins at angles of approximately 100 and 110 degrees.
Numerical Analysis for Investigation of Hydraulic Fracturing Potential of the Rockfill Dam
Authors: TOPÇU Sadettin , SEYREK Evren
Published: January 2024

Embankment dams may collapse because of internal erosion that develops in the crack developed in the upstream-downstream direction by hydraulic fracturing. It is known in the literature that many dams collapsed due to hydraulic fracturing. The hydraulic fracturing mechanism is defined as the propagation of an existing crack on the upstream face of the clay core under hydrostatic stresses or the formation of a new crack in low-stress zones by hydrostatic stress. The variety of materials and materials' mechanical properties generally affect the hydraulic fracturing potential. This study examined the effect of the deformation parameters (Elasticity modulus and Poisson ratio) of the impermeable curtain-function clay core material on the hydraulic fracturing potential. Normal Stress and Mohr-Coulomb methods were used to determine the hydraulic fracturing potential. The principal stress values required for these two methods were determined for the maximum cross-section of the clay-core rockfill type Çınarcık Dam by the finite element method. While the hydraulic fracturing potential is negligibly affected by the change of deformation parameters in the Normal Stress method, this effect is clearly seen in the Mohr-Coulomb method.

The awesome thing about language is that, well, we all mostly speak it, to some extent or another. This gives us an immensely powerful tool to manipulate transformational tasks. For the purposes of this post, I consider a transformational task to be essentially anything that takes an input and is largel intended to return some version of the same thing. This is not a very precise definition, but it will have to do for now.
BENEFICIAL IMPACTS ON IMMUNE RESPONSES AND DISEASE RESISTANCE OF WHITELEG SHRIMP (Litopenaeus vannamei) FED DIETARY HERBAL EXTRACTS
Authors: Mutunga Robert
Published: January 2024

The present study was conducted to determine the effective herbal extracts of Phyllanthus urinaria and Combretum quadrangulare incorporated into the diets on the health of whiteleg shrimp (Litopenaeus vannamei). A commercially available feed diet was incorporated with a concentration of 1% P.urinaria, 1% C.quadrangulare,1% of a mixture of both 1% P. urinaria and 1% C. quadrangulare Kurz (experimental diets), and no herbal extract (control treatment). Shrimps (1.05±0.33 g) in triplicate groups were fed with the supplemented diets for 4 weeks in a 500 L tank with a stocking density of 70 shrimp/tank. Hematological and immunological parameters (Total hemocyte count, granular cells, hyaline cells, phenoloxidase activity-PO, and immune gene expressions) were evaluated after the feeding trial. The results showed that after 4 weeks of dietary herbal supplementation of 1% P. urinaria (PUE), and 1% mixture of P. urinaria and C. quadrangulare (PUE-CQE) significantly enhanced hematological and immunological parameters (total hemocyte count, granular and hyaline cells, phenoloxidase, lysozyme, and Penaeidin-3). After being challenged against V. parahaemolyticus, cumulative mortality of shrimp in treatment of a 1% mixture of P. urinaria and C. quadrangulare (PUE-CQE) was lower compared to the positive control at 43.6% and 66.7% respectively and the difference was statistically significant (p<0.05). Dietary herbal-supplemented treatments of 1% CQE and 1% PUE were slightly lower than the positive control at 55.6% and 59.5% respectively hence no significant difference (p>0.05). This shows that all the herbal treatments lowered the susceptibility and increased protection against V. parahaemolyticus compared to the positive control. In summary, the results indicate that P. urinaria and C. quadrangulare dietary herbal extracts have beneficial impacts on immune responses and disease resistance in whiteleg shrimp (Litopenaeus vannamei) against V. parahaemolyticus.

Practical Application of Interceptors on Small Non-Planing and Slow Planing Powerboats
Authors: Grifka Ron
Published: January 2024

A surplus U.S. Coast Guard 26 foot Motor Surf Boat (MSB) was purchased and outfitted for use as a pleasure craft. This boat had been previously repowered by the Coast Guard and is capable of considerably higher speeds than the original design. The hull form has curved buttocks aft and a rounded transom which caused excessive trim at these higher speeds. The owner investigated a number of possible solutions to correct this excessive trim and selected installation of a fixed interceptor. This solution was believed to be simpler than installation of trim tabs, especially considering the rounded shape of the transom. However, there were two areas of uncertainty related to use of this devise on the MSB: (1) would an interceptor be effective on this hull form at the pre-planing and planning speeds; and (2) what size interceptor would be required to correct the trim problem? The following were the design considerations (1) the total project cost must be less than $3,500 The design must be able to allow for the installation of different interceptors without hauling the boat out of the water (3) the interceptor must be able to be removed from the boat leaving no trace of it’s existence if it did not improve the boats performance. To determine the length of the interceptor the transom was marked with masking tape at 4 inch intervals off the center line of the transom to aid in visual observation of water flow and set of pictures were taken of the stern wake as well as the water flow off the transom. It was believed that a minimum depth of an inch would be need to interrupt the water flow. Expectations (1) the interceptor would have no effect on the boat at run angle under 1500 RPMS and would only present a small fuel penalty (2) the interceptor would be effective above 1500 RPMS and make the boat more mannerly. A relatively small interceptor was found to be very effective reducing trim, improving fuel consumption and increasing maximum speed. This paper presents design details and trials results quantifying the performance improvements.
Modeling of Vertical-Plane Motions of a Tunnel Hull Boat
Authors: Chaney Christopher S. , Matveev Konstantin I.
Published: January 2024

Tunnel hull boats, capable of achieving speeds up to 150 knots, are among the fastest waterborne vehicles. A tunnel hull configuration consists of a platform and two side hulls. The weight of this craft is supported mainly by hydrodynamic forces on the hulls and aerodynamic force on the platform. Utilization of aerodynamic support usually improves the boat’s lift-drag ratio. However, it also leads to deterioration of stability characteristics. Frequent crashes of high-speed boats, including tunnel hulls, show the importance of stability issues. In this study, a mathematical model is developed for vertical-plane motions of tunnel hulls. Nonlinear formulations of the added-mass strip theory and extreme ground effect theory account for unsteady hydrodynamic and quasi-steady aerodynamic forces, respectively. The influence of the system’s geometrical and loading parameters on transitions to unstable regimes is demonstrated. Simulations of unsteady motions, such as responses to wind gusts and behavior in waves, are also shown. The developed mathematical model can be applied for design of a variety of fast boats with aerodynamic support.
Evaluation of High-Speed Craft Designs for Operations in Survival Conditions
Authors: DeBord Frank , Stambaugh Karl , Barry Chris , Schmid Eric
Published: January 2024

Designs for high-speed planing craft are typically driven by performance on plane in operating sea conditions. These conditions govern the principal characteristics, installed power, structural design and design features related to seakeeping and handling. When these high-speed craft are operated for military, law enforcement or search and rescue missions, performance and safety in severe seas at low speed can become issues and should be considered during design. This paper discusses the issues related to operations in these survival conditions and provides examples of performance analyses related to: (1) stability and flooding; (2) capsize, broaching and control problems; (3) structural design; and (4) seakeeping motions and acceleration affects on crew, machinery and systems. For each of these aspects of performance, analysis methodologies are discussed and typical results are provided. Methods for comparing risks associated with operations in various sea conditions are developed and recommendations are formulated for definition of limiting conditions. Finally, areas where typical design practices are found to be deficient related to these survival operations are identified and discussed.
Wave Height and Planing Hull Wave Slams in Regular Waves
Authors: Judge Carolyn , Mychalowych Alexander , Slater Rachel
Published: January 2024

High-speed planing boats are subject to repeated slamming impacts. These impacts can cause structural damage and discomfort, or even injury, to passengers. The motivation for this research is to determine a relationship between wave height and vertical accelerations of planing crafts. A series of towed-scale model experiments was conducted in regular waves to capture a sequence of individual impact events. The experiments were conducted in a 380-foot long, 26-foot wide, and 16-foot deep tow tank at the US Naval Academy. Two model scales of the same geometry were tested at different Froude numbers and over regular waves with different wave heights. Wave height was varied using two methods. The first method was to keep the wavelength constant and increase the wave height. This produced waves with a larger wave slope, as well as the larger wave height. The second method was to keep the wave slope constant, thus increasing the wavelength along with the wave height. Vertical accelerations were measured at three locations (the LCG, the bow near the FP, and a point between the bow and LCG). Each wave encounter was treated as an individual slam event. The acceleration time histories were separated into individual impacts. All impacts show a general shape. There is strong agreement in the overall shape of the impact event. The peak vertical accelerations depend on the ratio of wave height to boat length squared, the square-root of the wave slope, and the boat speed squared. This paper will explain the methodology for separating impacts in regular waves as well as the scaling relationships for peak acceleration magnitudes and full acceleration impact time histories.

Educación problematizadora de Paulo Freire
Authors: Cuello Romero Corina
Published: January 2024

El presente artículo tiene como propósito brindar una reflexión teórica al discurso Freireano sobre la educación problematizante de Paulo Freire, siendo de interés abordar los aportes del autor en cuanto a la perspectiva antropológica y epistemológica que subyace en la metodología educativa propuesta. Este documento de carácter reflexivo se sostiene en dar cuerpo interpretativo a una educación problematizadora atendiendo a los postulados de Freire (1970, 1971); el cual encausa en la praxis educativa como una acción dialógica y democrática sujeta a conceptos tales como: pedagogía, emancipación, política, transformación social, educación bancaria, dialogo y dialéctica, que permiten develar las intencionalidades en las interrelaciones educando-educador. Por tanto, el artículo se sustentó en los postulados Freire (1970); y se complementó con los planteamientos de otros autores como: Walsh (2013), Cabaluz (2015), Dussel (2013), De Souza Silva (2013), entre otros. La metodología se enmarcó en el enfoque interpretativo en la modalidad hermenéutica, con un diseño de análisis documental bibliográfico, sustentado en los contenidos de las distintas fuentes. A manera de reflexión final se expresa que la educación problematizadora, desde la perspectiva antropológico ve al ser como un proyecto inacabado y en constante construcción donde la educación liberadora invita al sujeto a tomar conciencia de su rol paradigmático de la transformación de su realidad opresiva.

Authors: Samba Stephen , Estreed Merna , Arogo Rita , Kireki Fredrick
Published: January 2024

Background: There exists an unmet need for timely initiation of reliable postpartum contraception among mothers. This could result in unplanned and closely spaced pregnancies that may endanger the lives of the mother and the unborn baby.

Case presentation: A 22-year-old para 1+0 presented to the emergency department with gradual onset of lower abdominal pains, per vaginal spotting, and bloating 10 weeks after childbirth. She reported full-time breastfeeding and regular and consistent use of male condoms for contraception. A diagnosis of ectopic pregnancy was established following a positive urine pregnancy test and a transabdominal ultrasound that revealed features of right tubal pregnancy. Exploratory laparotomy and partial salpingectomy were performed. The patient was stable and was discharged on the second postoperative day.

Conclusion: Early return of fertility in exclusively breastfeeding mothers is possible; hence, an effective family planning method is needed during the postpartum period to minimize the complications of short interpregnancy intervals.
Heavy metal and bacterial water filtration using Moringa oleifera and coconut shell-activated carbon
Authors: Nadella Satvika , Nadella Latha
Published: January 2024

Scarcity of potable drinking water exposes people to dangerous impurities – i.e., lead, copper, nitrates, and Escherichia coli – that contribute to life-threatening health concerns and are subsequently detrimental to the environment. Current, complex water filtration systems, most commonly reverse osmosis (RO) water filtration systems, remove some heavy metals and bacteria, but are chemically based and expensive to install and maintain. Moringa oleifera, commonly referred to as moringa, is a vegetable tree that produces leaves and fruit with both antibacterial and filtration properties for the removal of bacteria, sediment, and heavy metals suitable for removing them from water. The purpose of this study was to examine the use of moringa seeds as a filtration material. To conduct this study, we filtered simulated polluted water containing lead oxide, copper, and ammonium nitrate with moringa. Our results showed that moringa seeds were an effective filtration material. However, the filtered water still contained a significant concentration of heavy metals. Therefore, to further purify the water, we added a coconut shell-activated carbon (CSAC) filter, which proved to remove 100% of the residual contaminants. A real-world testing sample from Elm Fork Trinity River water was also tested for both heavy metal elimination and bacterial filtration. Results revealed that after the two-stage filtration, E. coli was no longer in detectable range. Our study demonstrates an effective method of heavy metal and bacteria removal from polluted water. Using moringa seed powder and CSAC, this economical, readily available filter can prove to be a more efficient alternative than current RO Systems.

Las principales variedades de manzano en la sierra de Arteaga, Coah., presentan autoincompatiblidad y, por ende, bajo amarre de fruto. Una alternativa de solución es la polinización apícola, por ello durante 1996, en un huerto localizado en el ejido Los Lirios y plantado con las variedades Red y Golden Delicious se co1ocaron 9 colmenas al centro del huerto, y se seleccionaron 4 árboles por variedad, a distancias de 2, 81 y 144 m del apiario. Antes de la floración y en cada tratamiento, se cubrieron con tela de tul 80 yemas (flores sin abejas) y se etiquetaron 80 yemas (flores con abejas), en el mismo árbol. Se determinó la fuerza de las colmenas, y se calculó el porcentaje de amarre de fruto a 11 días de floración completa, analizándose con un diseño factorial 2 x 2 x. Además, se cosecharon 25 frutos por tratamiento, registrándose lóculos con semilla y número de semillas por fruto, por su relación con la polinización. Los resultados indican que la presencia de abejas en floración favorece el amarre de fruto en 75 % para Golden Delicious y 76.5 % para Red Delicious. Los datos del huerto en estudio se comparan con un huerto de manejo intensivo con mayor número de colmenas por hectárea y el suministro de polen en la piquera de las colmenas.

Se observó la presencia de insectos del género Neochhetina spp, atacando lirio acuático, se evaluó su fluctuación poblacional, con el fin de conocer su comportamiento para establecer estrategias de control de esta maleza acuática; se localizaron mayor número de insectos cuando las plantas de lirio acuático eran más grandes, y cuando el número de mordeduras en las hojas también era mayor. Los muestreos se realizaron de mayo de 1996 hasta abril de 1997. Además se desarrolló un trabajo experimental de combate químico sobre lirio acuático, con dos herbicidas y un testigo, encontrando que el herbicida 2,4-D, fue el que mejor actuó sobre las plantas de lirio acuático, el herbicida Glifosato no presentó el mismo control que el herbicida 2,4-D.

Esta investigación se llevó a efecto con la finalidad de determinar la susceptibilidad de larvas de Amphidees latifrons Sharp a diferentes dosis de insecticidas. Los estudios se realizaron con larvas de tercer estadío, utilizando la técnica de aplicación tópica, se colocó 1 mg de insecticida sobre el tórax del insecto, observando a las 24 h el número de individuos muertos, de acuerdo al criterio de muerte establecido. Se evaluaron insecticidas de los grupos fosforados, carbámicos, dorados y piretroides. En las evaluaciones con insecticidas los mejores resultados se obtuvieron con la cipermetrina y el clorpirifos ya que presentaron las DL50 más bajas, con 29.35 μg g-1 y 32.36 μg g-1, respectivamente; aunque el carbofuran (40.42 μg g-1), paration metílico (42.99 μg g-1) y metamidofos (45.16 μg g-1) presentaron valores cercanos. La cipermetrina mostró una proporción de eficiencia mayor, siendo 4.83X (veces) mas eficiente que el diazinon, y 3.02 más que el endosulfan, el resto de los productos se ubican entre 1.10X y 1.69X.

Linguistic Perceptions of Irish English in Nineteenth-century Emigrant Letters
Authors: Amador-Moreno Carolina P. , Ruano-García Francisco Javier
Published: January 2024

In this paper we look at the real voices of Irish English speakers in the nineteenth century. By turning to the Corpus of Irish English Correspondence (McCafferty & Amador-Moreno, 2012), we analyse the perceptions that letter writers had of their own language use. We apply a micro-perspective analysis to the language of John Kerr, an Irish emigrant to America, in his letters to his uncle James Graham of Newpark (Co. Antrim, N. Ireland). We examine Kerr’s incisive comment on language use alongside metacommentary found in different Late Modern works, including dictionaries, essays on Irish English, as well as contemporary fictional representations of the variety of English spoken in Ireland during this period. Through this small batch of letters, we explore how the real voices of Irish English speakers echoed an enregistered Irish repertoire that may have raised awareness shaping their perceptions of their own dialect.

Ngadilegi Utara Hamlet is one of the hamlets in Plinlahan Village, Pandaan District, Pasuruan Regency which has large potential land for cultivating plants. Farmers in Ngadilegi Hamlet grow many crop commodities, one of which is melons. Melon (Cucumis melo L) is an annual fruit plant originating from the Persian Hot Valley or the Mediterranean region which is the border between West Asia, Europe and Africa. Melon plants are a type of pumpkin plant which is in the same family as watermelon, cantaloupe and cucumber. One effort to increase melon production in North Ngadilegi Hamlet can be done by good development and correct cultivation technology and supported by the use of new technology, namely the use of bacteria contained in PGPR. Soaking seeds with PGPR aims to ensure that the bacteria contained in PGPR are able to colonize the seeds as early as possible. Proper long soaking treatment of seeds can increase plant yields because bacteria will bind to the seed coat and imbibition into the seeds.
