Published: April 2024

Background: Excessive internet usage has become a significant issue among adolescents and young adults, affecting their physical, mental, social, and emotional well-being. In the Pakistani context, this trend is particularly concerning due to limited digital literacy and awareness of the negative effects of internet overuse. Aim: This study aims to explore the impact of excessive internet usage on the emotional maturity of adolescents in Pakistan, analyzing how limitless internet access contributes to physical, mental, and social challenges among this age group. Methodology: The research adopts a qualitative approach, reviewing existing literature on internet abuse and its repercussions on the physical, mental, and emotional health of Pakistani adolescents. The study analyzes key factors contributing to the decline in emotional maturity due to excessive internet use. Results: The findings indicate that high levels of internet usage are closely associated with reduced emotional maturity among adolescents. This reduction is manifested through various issues, including increased mental stress, decreased physical activity, and deteriorated social relationships. Conclusion: The study concludes that excessive internet usage can significantly impact the emotional development and maturity of adolescents, leading to a range of mental, physical, and social problems. It underscores the need for interventions that promote balanced internet use and enhance emotional resilience among Pakistani youth.
Computer assisted personality analysis (CAPA) and simulation (CAPS)
Authors: Pierson George R.
Published: April 2024

This paper discusses the development of technology designed to simulate hypothetical personality structures and to predict specific behaviours as a consequence of personality and situational interactions.4 This device should be useful in theoretical psychology to pose questions of the "What would happen if...?" variety. The program can also evaluate a different kind of questions, "Given the present personality structure of an individual, as a set of dependent variates, what might one predict his behaviour to be if...?" Examples are given of the use to which the personality simulator has been put. Some potential uses are suggested.
A large sample cross-check on 16 P.F. primary structure by parcelled factoring
Authors: Cattell Raymond B.
Published: April 2024

Some disputes about primary personality structure on Q-data suggested the need for an entirely fresh analysis unbiased by existing scales. Both to achieve this and to check some superiorities claimed for radial parcel over items factoring, 184 16 P.F. items were given to 780 adults. Reduced by radial parceling to 46 variables, they factored to 20 factors (19 having been found in item and scale factoring) which rotated to a statistically significant simple structure. Despite slight alterations by approximation which followed in projecting these factors on the items the item patterns significantly matched, by two indices: (a) the original "ideal" 16 P.F. keys for the primaries, and (b) an independent factoring of the same items as items. It is concluded that the 16 P.F. primaries are well confirmed ans that parceled factoring can in some respects exceed the precision of item factoring.
An investigation of the common factor space of some well known questionnaire scales: the Eysenck EPI, the Comrey scales and the IPAT Trait-State kit (CST)
Authors: Barton Keith , Cattell Raymond B.
Published: April 2024

In the domain of measurement of personality by questionnaire, the last decade has been one of integration. At least among the designers of factored scales, if not among others, there have been attempts systematically to discover the common factor space and the relative standing of the various scales therein (Cattell, 1973; Comrey & Duffy, 1968; Derman & Harman, 1973; Eysenck & Eysenck, 1968).

Authors: Nurul Fadilah
Published: April 2024

Defending the State or what can be called national resilience is an important thing in state life. The attitude of defending the country is something that must be owned and realized by the people, especially the younger generation who will be the future leaders of the nation. Article 27 paragraph (3) of the 1945 Constitution states that "every citizen has the right and obligation to participate in efforts to defend the State". This research uses the literature review method which is a systematic, explicit and reproducible method for evaluating and identifying research works. The aim of this research is that citizens, especially the younger generation, must have a responsibility to defend the country and prepare students to become good citizens. The results of the discussion show that to realize the 1945 Constitution concerning National Defense, the government provides citizenship education to help educate citizens, especially the nation's next generation. Through citizenship education, the descendants of the Indonesian people will be able to understand, analyze and answer the challenges faced in society, nation and state. As well as being sustainable and in accordance with the principles and ideals of the nation as intended in the preamble to the 1945 Constitution. It is hoped that awareness of defending the State or national security can be instilled in the minds of all Indonesian people, especially in this technological era. Because in the technological era there are several external threats that are sometimes overlooked.

Induced Magnetization in Antiferromagnetic GdFeO3 by Nonmagnetic Titanium Substitution for Magnetic Switching and Storage Application
Authors: Shah Jyoti , Kotnala R K ,   CSIR-National Physical Laboratory, Delhi-110012, India
Published: April 2024

Room temperature ferromagnetism has been induced in antiferromagnetic GdFeO3 by substituting titanium at Gd site Gd1-xTixFeO3 (x=0.00 - 0.25). Perovskite GdFeO3 has been synthesized at lower temperature by chemical co-precipitation. Titanium substitution in gadolinium orthoferrite has transformed the perovskite phase to garnet phase confirmed by X-ray diffraction analysis. Tolerance factor of perovskite structure has been reduced from 0.81 to 0.78 for x=0.25 Ti substitution. Antiparallel G-type electron spins of GdFeO3 has been distorted by structural change induced due to titanium substitution. Ferromagnetism has been increased to 0.74 emu/g from 0.5 emu/g by titanium substitution. Retentivity and coercivity has been also increased from 0.005 emu/g to 0.28 emu/g and 27 Oe to 218 Oe respectively. The increase in magnitude of ferromagnetic transition with respect of temperature has been significantly observed by high temperature magnetization measurement. Present process is easy to induce room temperature ferromagnetism in antiferromagnetic GdFeO3 by distorting the structure at lower temperature by titanium substitution. The retentivity and coercivity produced at x=0.25 titanium substitution is useful for magnetic memory and switching application.

Authors: Arhin Ebenezer Prince , Cobblah Collins
Published: April 2024

This study shed additional understanding on how Total Quality Management (TQM) practices affect customer satisfaction through the innovative behavior of employees. Based on quantitative data from the 5 Teaching Hospitals in Ghana, this study employed a multistage sampling procedure to analyze the relationship between innovative employee work behavior and total management commitment, Training and Education, Performance Management System, Supplier Management, and innovative employee work behavior. We find that these relationships are positive and that the relationship between TQM practices and customer satisfaction is mediated by innovative employee work behavior. In addition to theoretical contributions to the field of TQM and healthcare systems, these results have managerial implications for hospital professionals who work at prioritizing the adaptation of TQM practices.

Authors: Wang Johnny
Published: April 2024

Drawing a qualitative case study over two years during, this paper provides a detailed sociological account of the local practices and institutional logic and found out that local teams used selective coupling, which led to hybrid practices such as delegation and bricolage. These findings can help top-level manager enhance their awareness of the issues raised by the ERP implementation across organizations. Understanding the constellation of institutional logic within the organization can direct their attention toward new perspectives, thus creating opportunities to influence institutional change. This study analyzes the institutional contradiction during post-implementation from the perspective of flexible coupling and provides further evidence from a completely different context, namely the cross-border implantation in the industrial sector, and within the organization.

International legal means of protecting human rights in health emergencies
Authors: Malichenko Vladislav Sergeevich
Published: April 2024

The subject of the study is international legal norms, documents of international organizations (of a recommendatory and binding nature), as well as acts of domestic law establishing guarantees for ensuring the human right to health and the right to use the results of scientific progress, as well as forming international legal mechanisms for the protection of intellectual property and technology transfer. The object of the study is public relations arising from the interaction of various subjects of international relations in the framework of countering emergencies in the field of health protection and ensuring equitable access to healthcare technologies in all regions of the world, regardless of the level of development of the pharmaceutical industry. The purpose of the study is to develop proposals for the introduction of international legal means aimed at ensuring the human right to health in the framework of achieving a balance of public and private legal guarantees of access to healthcare technologies. The research methodology is based on general scientific methods of cognition, including formal logical and situational, and private legal methods such as comparative-legal, historical-legal and formal-legal. The past decades have been accompanied by rapid rates of emergency situations in the field of public health, which have demonstrated systemic problems in the organization of medical care in each State, as well as revealing imperfections in international legal regulation of the field of health protection. Healthcare technologies, which determine the effectiveness of countering any large-scale threat of an infectious and non-infectious nature, in the vast majority of cases are developed by non-State actors, the main purpose of whose activities is legitimately to make a profit. At the same time, the obligation to ensure the right to the highest attainable standard of health and access to health technologies rests with the State, which forms stable barriers to ensuring a balance of public and private legal guarantees in the field of health protection. The paper presents a list of the main problems of international legal response to emergencies of international importance. The article consistently reveals the main international legal means of ensuring the transfer of healthcare technologies. The authors have formulated a number of practical recommendations aimed at expanding access to healthcare technologies.
Analysis of drought and heat stress response genes in rice using co-expression network and differentially expressed gene analyses
Authors: Cao Gaohui , Huang Hao , Yang Yuejiao , Xie Bin , Tang Lulu
Published: April 2024

Studies on Oryza sativa (rice) are crucial for improving agricultural productivity and ensuring global sustenance security, especially considering the increasing drought and heat stress caused by extreme climate change. Currently, the genes and mechanisms underlying drought and heat resistance in rice are not fully understood, and the scope for enhancing the development of new strains remains considerable. To accurately identify the key genes related to drought and heat stress responses in rice, multiple datasets from the Gene Expression Omnibus (GEO) database were integrated in this study. A co-expression network was constructed using a Weighted Correlation Network Analysis (WGCNA) algorithm. We further distinguished the core network and intersected it with differentially expressed genes and multiple expression datasets for screening. Differences in gene expression levels were verified using quantitative real-time polymerase chain reaction (PCR). OsDjC53, MBF1C, BAG6, HSP23.2, and HSP21.9 were found to be associated with the heat stress response, and it is also possible that UGT83A1 and OsCPn60a1, although not directly related, are affected by drought stress. This study offers significant insights into the molecular mechanisms underlying stress responses in rice, which could promote the development of stress-tolerant rice breeds.
Cuidar en comunidad: La junta de vecinos como articulador socioespacial de cuidados
Authors:   , Zambrano Palma Matías Arnaldo
Published: April 2024

Se evidencia que los adultos mayores o jubilados no tienen un espacio físico más allá de lo doméstico, siendo segregados de la vida pública y su actividad. La plaza y el parque no otorgan la misma protección física de un interior, ni tampoco la cercanía social que lugares como el trabajo o el colegio le ofrecen a otros grupos etarios. La falta de lugares comunes que permitan el agenciamiento de este grupo y el encuentro intergeneracional, se vuelve una prioridad en el resguardo de sus derechos y los actos de cuidar.Un espacio donde este grupo accede a la participación en sociedad resultó ser la junta de vecinos, presente en múltiples puntos de la ciudad. Relacionadas al Estado mediante los recursos y programas que adquieren por parte de su respectiva municipalidad, y encargadas por ley de velar por el resguardo e intereses de la comunidad, permiten un rol activo del adulto mayor en el sistema social. Con diversidad de dinámicas y usuarios según la mixtura social que presenta su respectiva unidad vecinal, suelen ser frecuentadas y dirigidas por personas mayores, así como otros usuarios que tienden a permanecer en el hogar. Aunque sin exclusión de otros perfiles o rangos etarios que se pretenden integrar en sus tiempos libres o posterior a su jornada laboral.De forma que ante un espacio que resulta intermedio entre lo público y lo particular, adquiriendo forma de casa, departamento o local, e incluso compartiendo dependencias con jardines infantiles o centros deportivos de administración municipal. Es que se sugiere que las juntas de vecinos no responden a una tipología ni a un patrón de forma en que se puedan encasillar. Recayendo una serie de interrogantes respecto a esta figura que se procederá a levantar: ¿cómo es una junta de vecinos?¿qué espacios dispone para que se genere el encuentro y los actos de cuidar?¿cómo interviene la arquitectura en la promoción de estos lugares y su integración a las localidades y barrios de la ciudad?
Iluminación, clima y comunicación: La envolvente del Edificio Reval
Authors:   , Di Próspero Josefina María
Published: April 2024

La envolvente es la imagen de un edificio. Su materialidad y sus distintos componentes le otorgan una idea a la ciudad de lo ocurre dentro de la estructura, y es justo a partir de estos que podemos suponer para lo que es utilizada una estructura. Además, entre aquellos elementos originales y aquellos que se fueron agregando con el tiempo podemos construir una historia y sacar conclusiones sobre las falencias de un edificio.Así pues las envolventes son quizá una de las piezas más importantes de todo proyecto, ya que funcionan como un intermediario entre un interior y un exterior, entre edificio y ciudad, entre un programa y su contexto. No solo influencian en la percepción que nosotros tenemos del edificio sino que también sus distintas características o elementos pueden condicionar la forma en que nosotros nos comportamos en un interior. La cantidad de luz o la cantidad de ruido o de calor que éstas dejan traspasar generan distintos espacios interiores y formas de utilizarlos. De esta manera, es importante conocer las distintas variables que componen una envolvente, y la influencia que dichas variables pueden tener sobre el edificio en su totalidad. Entendiendo que un tipo específico de envolvente o los distintos cambios que le ocurren a esta, pueden significar un cambio en el uso de la estructura.La fachada del Edificio Reval es un caso especial dentro de lo que es el centro de Santiago. Su forma cilíndrica con vista 360° y su condición vidriada hacen que la torre destaque en comparación con el centro cívico. Sin embargo, con el tiempo la envolvente del edificio ha ido incorporando artefactos como equipos de aire acondicionado y carteles publicitarios, elementos que dan cuenta de ciertos cambios y problemas en el diseño de la torre. Donde quizá su cambio más llamativo sea la mutación que ha tenido con respecto al uso, pasando de ser departamentos a oficinas.Tomando en consideración estos problemas aparece una idea de reprogramar el Edificio Reval para convertirlo en una biblioteca y centro de investigación universitario, a partir del diseño de una nueva envolvente. Ciertamente, un espacio donde se conservan libros no requiere de las mismas condiciones lumínicas y climáticas que un espacio para la lectura o un espacio más público como una cafetería o un restaurant. El hecho de hacer una misma envolvente con cualidades distintas dependiendo de las condiciones exteriores permite darle más valor al edificio y crear distintas situaciones que vayan de la mano con un tipo específico de envolvente. Por el otro lado, en Santiago Centro hoy por hoy existen múltiples universidades e institutos que fragmentan el conocimiento en distintas sedes, y por tanto, existe un potencial en que puedancomplementarse y unificarse para crear un gran centro de estudio donde el conocimiento sea accesible a todos.
La brecha salarial de género en Chile: un enfoque de industrias
Authors:   , Apablaza Quitral Valentina , Fantoni Izquierdo Dominga
Published: April 2024

La brecha salarial de género es un fenómeno que ha ido disminuyendo en el tiempo, pero que siguesiendo una problemática relevante para la mayoría de los países. Aun cuando dicho fenómeno se haestudiado ampliamente en la literatura, los determinantes detrás de la brecha y su aporte, están lejosde ser un tema zanjado. Esta investigación busca estimar la brecha salarial para el caso chileno, analizando sus principales determinantes y sus contribuciones, lo cual es de suma importancia para el diseño de políticas públicas que combatan la diferencia de ingresos entre los sexos. Para este análisis se utilizan los datos recopilados por la encuesta CASEN, separando la muestra por nivel educacional, y se utiliza la descomposición Blinder Oaxaca, metodología que además de identificarla contribución de componentes observables a la brecha salarial, permite visualizar el componenteno explicado de esta. Los resultados indican que la brecha por hora para quienes asistieron a laeducación superior alcanza un 26 % y supera la de quienes no lo hicieron (23 %). La principalexplicación de este fenómeno, es que en el último grupo las mujeres están más educadas que loshombres, a diferencia del primer grupo de comparación.Finalmente, el análisis se desagrega a nivel industria y según otras características pertinentes, locual no se ha realizado previamente para Chile. Lo anterior es clave para evaluar cómo el comportamiento y la magnitud de la brecha difiere para distintas industrias. Se concluye que la industriacon mayor brecha entre las personas con mayor nivel educacional es Agricultura (37 %), y entre losmenos educados es Servicios comunales (28 %), siendo esta última la industria con mayor participación femenina. Adicionalmente, se concluye que, en caso de quienes poseen educación superior,la menor brecha está en Minas, sin embargo, se encuentran indicios de discriminación en esta industria. Por el lado de los que no asisten a la educación superior, la menor brecha se encuentra enConstrucción, porque las mujeres realizan oficios más calificados en este sector.
Achieving a proactive policy for patient flow management in a complex hospital network through reinforcement learning
Authors:   , De Geyter Messina Matías
Published: April 2024

La toma de decisiones en el cuidado de la salud es un problema complejo debido a la incertidumbre y la realidad dinámica. Un tema muy importante está relacionado con las decisiones sobre admisiones de pacientes. En una red de atención médica compuesta por varios hospitales, debería ser conveniente considerar la capacidad combinada de todo el sistema. Por lo tanto, además de las admisiones a un hospital, también es posible transferir pacientes a otros. Estas decisiones dependen no solo de la condición médica del paciente, sino también de la capacidad actual de las diferentes áreas de los hospitales. En este trabajo, hemos formulado el problema como un Proceso de Decisión de Markov, y lo abordamos utilizando un enfoque de Aprendizaje por Refuerzo donde se estima el costo futuro esperado utilizando un modelo XGBoost, combinado con simulación, basado en la metodología de Q-learning. Basándonos en la política obtenida a traves del aprendizaje por refuerzo y en nociones de la literatura, se proponen pautas generales de gestión hospitalaria, que resultan en una política simplificada y fácil de implementar con resultados prometedores, incluída una reducción en el tiempo de servicio promedio en un 13.38% y una reducción del tamaño de la lista de espera del 65.86%. En comparación con el escenario base, hay una reducción en los costos totales del 71.44%, donde los costos sociales (debidos a los tiempos de espera y los costos de oportunidad de las camas para pacientes) se reducen en un 87.30%.
Analysis of the microstructure and electrochemical properties of Cu-NiAl used for molten carbonate fuel cell
Authors:   , Arcos Segura Camila Fernanda
Published: April 2024

Global population growth has influenced further technological and scientific challenges, where the exponential increase in electricity demand stands out. In this context, it is necessary to continue researching alternatives to conventional energy generation to reduce greenhouse emissions. Fuel Cell technology is promising for lowering and storing carbon dioxide emissions in this context. It is a backup system to avoid intermittent problems with wind, solar, or other technologies. Fuel cells correspond to an electrochemical device that converts the chemical energy of a fuel directly into electrical energy. Their main components are the electrodes (anode and cathode), electronically conductive, and electrolyte. In particular, molten carbonate fuel cells use hydrogen as fuel, highlighting their excellent power. However, the high working temperature, close to 650 °C, is a disadvantage due to the reduction of the component’s lifetime. Therefore, for a long-term operation, electrode corrosion behavior must be considered. This thesis aims to study Cu-Ni-Al alloys' microstructure and electrochemical behavior for molten carbonate fuel cells. The metal samples were manufactured using powder metallurgical techniques, such as hot pressing and additive manufacturing. The porosity was analyzed using the Archimedes method. The micro-macrostructure of the samples will be studied before and after exposure to Li2CO3-K2CO3 at 550 °C using surface analysis, such as optical microscopy, field emission scanning electron microscopy, and X-ray diffraction. Moreover, gravimetric measurements before and after exposure and electrochemical impedance spectroscopy at open circuit potential were used to analyze the corrosion of the anodes in an aerated and controlled environment.
Análisis de la historia de Griselda del Decamerón desde una reescritura protofeminista realizada por Eleanora Louisa Hervey
Authors:   , Bardin Quesieh María Fernanda
Published: April 2024

Esta investigación pretende ampliar los estudios del libro The Feasts of Camelot: with the Tales that Were Told There (1863) de la escritora victoriana Eleanora Louisa Hervey, quien ha sido históricamente relegada del canon literario. En este sentido, las escasas investigaciones sobre su obra, llevadas a cabo en su mayoría por la académica Renée Ward, han demostrado un interés por recuperar a esta autora y sus escritos; sin embargo, sigue existiendo un gran vacío respecto a esta materia. En la presente investigación se busca evaluar, a partir de la intertextualidad, si la obra mencionada se puede catalogar como una reescritura protofeminista bajo una perspectiva traductológica enfocada en la traducción feminista (Flotow, 1991, 1997, 2019; Castro, 2008). De este modo, se analizó la reescritura de la historia de Griselda que se encuentra en los capítulos VI y VII de The Feasts of Camelot, a partir de su comparación y contraste con tres textos: la versión de la historia de Griselda presentada primero, en el capítulo “Décima Narración” de la “Décima Jornada” del Decamerón de Boccaccio, y las reescrituras posteriores realizadas por Petrarca y Chaucer. Debido a la inclusión de cambios temáticos y de focalización en la narración de Hervey que se vinculan a estrategias de traducción feminista como el secuestro, la retraducción y la selección estratégica de textos, la investigación dio como resultado que la historia de Griselda presente en la obra de Hervey constituye una reescritura protofeminista.
Non-Working Workers. The Spanish Labour Market under Covid-19
Authors:   Universidad Pablo de Olavide and FEDEA, García-Pérez José Ignacio , Villar Antonio ,   Universidad Pablo de Olavide and ISEAK
Published: April 2024

We propose in this paper a way of analyzing the evolution of unemployment that considers, besides conventional unemployment rates, unemployment duration, discouraged workers and workers with suspended jobs. Those variables are combined into a synthetic index of non-employment that can be expressed as the product of two components, incidence and severity. We apply this methodology to analyse the evolution of the Spanish labour market during one year with Covid-19. The data show that the behaviour of the job market has been very asymmetric by regions and types of workers. We find that not only incidence and severity are quite heterogeneous across regions and worker types, but also that the evolution between 2019 and 2020 has been different from that corresponding to the financial crisis, with high unemployment regions and older workers suffering less, in terms of incidence and severity.

African histoplasmosis is a rare deep mycosis caused by Histoplasma capsulatum var duboisii. It can affect various organs such as the skin, lymph nodes, and bones. The diagnosis is often delayed due to its similarity to certain diseases such as tuberculosis, cryptococcosis, pyogenic abscesses, and even neoplasia. We report a case of cutaneous and osseous histoplasmosis caused by H. capsulatum var. duboisii in a seemingly immunocompetent 19-year-old senegalese woman who presented with chronic disseminated cutaneous abscesses, some of which had fistulised, and umbilicated papules on the face. The radiograph of the right forearm showed a metaphyso-diaphyseal osteolytic lesion of the ulna. Histology after biopsy of a facial papule confirmed the diagnosis of histoplasmosis caused by H. capsulatum var duboisii. The patient's condition improved with fluconazole treatment.
A Comprehensive Review on Soilless Cultivation for Sustainable Agriculture
Authors: Kumar Tammineni Varun , Verma Ravi
Published: April 2024

With the growing challenges of food security and environmental degradation, there is an increasing need for sustainable agricultural practices. Soilless cultivation techniques offer a promising solution by minimizing land and water use while maximizing crop yield and quality. This review examines the potential of soilless cultivation methods in promoting sustainable agriculture. The purpose of this review is to evaluate the effectiveness of soilless cultivation techniques in sustainable agriculture. It aims to analyze the various methods used, their advantages and limitations, and their contributions to environmental sustainability and food security. A comprehensive literature review was conducted to gather information on soilless cultivation techniques, including hydroponics, aeroponics, and aquaponics. Relevant studies and reports were analyzed to assess the performance of these methods in terms of resource efficiency, crop productivity, and environmental impact. The review found that soilless cultivation techniques offer significant advantages over traditional soil-based farming, including higher crop yields, efficient water and nutrient use, and reduced environmental footprint. Hydroponic systems, in particular, have been widely adopted and have shown promising results in various crops. Additionally, soilless cultivation methods can be tailored to different environmental conditions, making them adaptable to a wide range of settings. In conclusion, soilless cultivation holds great potential for sustainable agriculture by addressing key challenges such as land and water scarcity, soil degradation, and climate change. While further research and technological advancements are needed to optimize these techniques and make them more accessible to farmers, the evidence suggests that soilless cultivation can play a significant role in achieving global food security and environmental sustainability goals.
Petroleum Exploration in the Niger Delta Region and Implications for the Environment: A Review
Authors: SJ Olukaejire , CC Ifiora , PA Osaro , LC Osuji , AI Hart
Published: April 2024

Petroleum exploration and production in the Niger Delta, Nigeria, has been a significant source of revenue and foreign exchange for the country. Nevertheless, this industry has also been blamed for serious environmental pollution in the region. This review aims to shed light on the implications of petroleum exploration in the Niger Delta region and the resultant environmental damage it has caused. One of the most severe consequences of petroleum exploration in the Niger Delta is the frequent occurrence of oil spills. Due to aging infrastructure, poor maintenance, and criminal activities such as oil theft, pipeline spills have become a recurrent problem. Oil spills lead to the destruction of farmland, loss of biodiversity, poisoning of water sources, and widespread contamination of ecosystems. Petroleum exploration and production activities release substantial pollutants into the atmosphere, posing a significant threat to both human health and the environment. The burning of natural gas during oil production, also known as flaring, is particularly prevalent in the Niger Delta. This practice results in the emission of toxic gases such as carbon dioxide, methane, and sulfur dioxide, contributing to climate change, respiratory diseases, and acid rain. Petroleum exploration in the Niger Delta has led to significant damage to forests and mangrove ecosystems. The destruction of these vital habitats has serious implications for species survival. Oil exploration activities often release harmful chemicals and wastes into the region's water bodies. These pollutants infiltrate the groundwater and surface water, leading to contamination that poses severe risks to human health and aquatic life. Contaminated water supplies have been linked to increased instances of skin diseases, as well as liver and kidney problems among the local population. The negative environmental implications of petroleum exploration in the Niger Delta also have severe socioeconomic consequences. Displaced fishermen and farmers face declining livelihoods, while sporadic employment opportunities generated by the oil industry do not compensate for the long-term damage inflicted on the region.

In this research, many materials used as shields against ionizing radiation (neutrons and gamma rays) were studied. Seven glass systems compounds and five polymeric compounds were used to test their effectiveness in attenuating fast neutrons. These compounds are (S1-S7) as shown in table (1) and polymeric compounds as shown in table (3), many attenuation coefficients for these compounds were calculated through the use of a computer program called (SAZ) written in the Python programming language, which is used to calculate a number of basic parameters based on certain semi-empirical equations. The results showed that the sample (S7) and C9H9O is the best glass system compound and polymeric compound for neutrons attenuation, because they have a largest value of ΣR. Also, a number of Eco-friendly metallic compounds as shown in table (2) were used, to test them in shielding against gamma rays. The mass attenuation coefficient was calculated through the NIST-XCOM program for a range of energies starting from 59.53 keV up to 1 GeV. These compounds differed in their ability to attenuate gamma rays, as the results showed that the best studied compound against gamma rays was the PbS compound because it contains the Lead element, which has a largest atomic number.

Published: April 2024

The evolution of wireless communication technologies has led to the widespread adoption of Wireless Local Area Networks (WLANs). IEEE 802.11n provides many enhancements in physical and MAC layers such as (channel bonding(CB), Multiple Input/Output (MIMO), frame aggregation and block acknowledgment) to achieve higher throughput and improved reliability. As a result, CB is a key technique for enhancing the performance of wireless network. It is frequently used in various fields, such as workplace networks and live streaming. This research paper focuses on analyzing the effect of channel bonding on the performance of the IEEE802.11n WLANs, especially in two terms (throughput and delay). By using the OPNET (Riverbed) Modular version 17.5, five various number of nodes (5, 10, 15, 18 and 30 nodes) uniform topologies are modeled and simulated to investigate the WLANs performance for various MIMO up to 4 SS. Simulation outcomes indicated that applying of CB enhanced both delay and velocity performance. Specifically, in the scenarios (30 nodes), for MIMO (4×4) spatial streams, the average throughput value for channel bonding is (157.28 Mbps) compared to (87.41 Mbps) for no-channel bonding, and the average delay value for channel bonding is (0.0476 Sec) compared to (0.06762 Sec) for no-channel bonding. The enhancement values in the performance of WLANs are 42% and 79.9% for latency and throughput (velocity), respectively.

This unit describes a simple and efficient synthesis of the phosphoramidite derivative of N1‐methyl‐2′‐deoxyadenosine from 2′‐deoxyadenosine. The synthesis starts with the monomethoxytritylation of 2′‐deoxyadenosine followed by methylation of 5′‐O‐protected nucleoside at N‐1. Subsequent N‐chloroacetylation leads to N6‐chloroacetyl‐N1‐methyl‐5′‐O‐(p‐anisyldiphenylmethyl)‐2′‐deoxyadenosine, which is finally converted to its 3′ phosphoramidite derivative. This phosphoramidite is used to incorporate N1‐methyl‐2′‐deoxyadenosine into synthetic oligonucleotides. N‐Chloroacetyl protection and controlled anhydrous deprotection conditions are used to avoid the Dimroth rearrangement. Curr. Protoc.

Socio‐economic, socio‐political and socio‐emotional variables explaining school bullying: a country‐wide multilevel analysis
Authors: Chaux Enrique , Molano Andrés , Podlesky Paola

Why do some countries, regions and schools have more bullying than others? What socio‐economic, socio‐political and other larger contextual factors predict school bullying? These open questions inspired this study with 53.316 5th‐ and 9th‐grade students (5% of the national student population in these grades), from 1,000 schools in Colombia. Students completed a national test of citizenship competencies, which included questions about bullying and about families, neighborhoods and their own socio‐emotional competencies. We combined these data with community violence and socio‐economic conditions of all Colombian municipalities, which allowed us to conduct multilevel analyses to identify municipality‐ and school‐level variables predicting school bullying. Most variance was found at the school level. Higher levels of school bullying were related to more males in the schools, lower levels of empathy, more authoritarian and violent families, higher levels of community violence, better socio‐economic conditions, hostile attributional biases and more beliefs supporting aggression. These results might reflect student, classroom and school contributions because student‐level variables were aggregated at the school level. Although in small portions, violence from the decades‐old‐armed conflict among guerrillas, paramilitaries and governmental forces predicted school bullying at the municipal level for 5th graders. For 9th graders, inequality in land ownership predicted school bullying. Neither poverty, nor population density or homicide rates contributed to explaining bullying. These results may help us advance toward understanding how the larger context relates to school bullying, and what socio‐emotional competencies may help us prevent the negative effects of a violent and unequal environment.

Electric Field‐Directed Convective Assembly of Ellipsoidal Colloidal Particles to Create Optically and Mechanically Anisotropic Thin Films
Authors: Mittal Manish , Furst Eric M.
Published: September 2009

A method of simultaneous field‐ and flow‐directed assembly of anisotropic titania (TiO2) nanoparticle films from a colloidal suspension is presented. Titania particles are oriented by an alternating (ac) electric field as they simultaneously advect towards a drying front due to evaporation of the solvent. At high field frequencies (ν > ∼25 kHz) and field strengths (E > 300 V cm−1), the particles orient with their major axis along the field direction. As the front recedes, a uniform film with thicknesses of 1–10 µm is deposited on the substrate. The films exhibit a large birefringence (Δn ≈ 0.15) and high packing fraction (ϕ = 0.75 ± 0.08), due to the orientation of the particles. When the frequency is lowered, the particle orientation undergoes a parallel–random–perpendicular transition with respect to the field direction. The orientation dependence on field frequency and strength is explained by the polarizability of ellipsoidal particles using an interfacial polarization model. Particle orientation in the films also leads to anisotropic mechanical properties, which are manifested in their cracking patterns. In all, it is demonstrated that the field‐directed assembly of anisotropic particles provides a powerful means for tailoring nanoparticle film properties in situ during the deposition process.

A conjugated polymer (CP) and molecular‐beacon‐based solid‐state DNA sensing system is developed to achieve sensitive, label‐free detection. A novel conjugated poly(oxadiazole) derivative exhibiting amine and thiol functional groups (POX‐SH) is developed for unique chemical and photochemical stability and convenient solid‐state on‐chip DNA synthesis. POX‐SH is soluble in most nonpolar organic solvents and exhibits intense blue fluorescence. POX‐SH is covalently immobilized onto a maleimido‐functionalized glass slide by means of its thiol group. Molecular beacons having a fluorescent dye or quencher molecule as the fluorescence resonance energy transfer (FRET) acceptor are synthesized on the immobilized POX‐SH layer through direct on‐chip oligonucleotide synthesis using the amine side chain of POX‐SH. Selective hybridization of the molecular beacon probes with the target DNA sequence opens up the molecular beacon probes and affects the FRET between POX‐SH and the dye or quencher, producing a sensitive and label‐free fluorescence sensory signal. Various molecular design parameters, such as the size of the stem and loop of the molecular beacon, the choice of dye, and the number of quencher molecules are systematically controlled, and their effects on the sensitivity and selectivity are investigated.
