Authors: Santos Natália da Conceição , da Silva Patrício Francisco
Published: November 2022

Sabe-se que a adesão ao tratamento antirretroviral representou, ao longo dos anos, melhoria na saúde e diminuição na mortalidade dos pacientes portadores de vírus da Imunodeficiência humana (HIV), Síndrome da Imunodeficiência Adquirida (AIDS). Infelizmente nem todas as pessoas que vivem com HIV/AIDS têm facilidade de aderir ao tratamento, de modo que a não adesão constitui um dos significativos problemas na Terapia Antirretroviral. Isso acontece porque o processo de adesão é um fenômeno multifatorial e dinâmico, abrangendo aspectos físicos, sociais, psicológicos, culturais e comportamentais. Reconhecendo as diversas e distintas constituições do tratamento antirretroviral, este estudo aborda, a partir da literatura produzida, a importância do farmacêutico no programa IST/AIDS na dispensação dos medicamentos antirretrovirais, com o objetivo de destacar as contribuições do farmacêutico no tratamento Antirretroviral. A metodologia do estudo compreende a Revisão de Literatura que permitiu uma análise de importantes estudos sobre o assunto abordado. Os resultados apresentados são consistentes ao reconhecer o caráter multifatorial do tratamento antirretroviral que consequentemente exige a contribuição de uma equipe multiprofissional e campo de saberes e o farmacêutico e a farmácia são imprescindíveis para a promoção de saúde às pessoas que vivem com HIV/AIDS.
On the Analytical Models of Protoplanetary Formation in Extrasolar Systems
Authors: Krot Alexander M.
Published: November 2022

In this work, we consider a statistical theory for a cosmogonical body formation (so-called spheroidal body) to develop the analytical models of protoplanetary formation in extrasolar systems. Within the framework of this theory, the models and evolution equations of the statistical mechanics have been proposed, while the well-known problem of gravitational condensation of infinite distributed cosmic substances has been solved. This paper derives the general equation of distribution of the specific angular momentum of forming protoplanets since the specific angular momentums (for particles or planetesimals) are averaged during a conglomeration process (under a planetary embryo formation). As a result, a new law for planetary distances (which generalizes Schmidt’s law) is derived theoretically. This paper develops also an alternative thermal emission of particles model of the formation of protoplanets in extrasolar systems. Within the framework of this model, the equation for the thermal distribution function of the specific angular momentums of particles moving in elliptical orbits in the gravitational field is derived. According to this thermal escape model, only 0.8% of the total number of particles in the solar system composing the protoplanetary cloud has angular momentum 15.6 times higher than the angular momentum of the remaining 99% of particles. This conclusion agrees completely with the known fact of a nonuniform distribution of the angular momentums in our solar system noted by ter Haar. As pointed out here, the exponential laws of planetary distances occur in some extrasolar systems.

La clasificación taxonómica de organismos generalmente involucra el análisis de sus características morfológicas. Sin embargo, los taxónomos tienen serios problemas al tratar de ubicar adecuadamente a individuos que perteneciendo a la misma especie, subespecie, variedad, línea, etc., presentan el mismo fenotipo. El fitomejorador necesita conocer sus plantas desde el punto de vista genético para incorporar eficientemente en sus programas a las que posean el mejor potencial; tal selección puede dificultarse si las plantas son fenotípicamente indistinguibles. Por lo general, los investigadores cruzan individuos sobresalientes y seleccionan las progenies, lo que les permite, a largo plazo, conformar variedades o líneas endogámicas. Este proceso es costoso económicamente y tardado. Con la finalidad de facilitar la apropiada selección de plantas, en la década pasada se desarrollaron técnicas moleculares que permiten conocer de manera inequívoca el perfil específico del ADN para establecer una tipificación única y confiable, referida como "huellas de ADN", así como la detección de marcadores asociados a diferentes aspectos tales como, resistencia a patógenos, a estrés o a rendimiento, entre otros. Por otro lado, estas técnicas también han permitido elaborar mapas genéticos en menor tiempo y conducir programas de mejoramiento genético más eficientes. El objetivo de este trabajo es describir algunas de estas técnicas utilizadas para tipificar genomas vegetales, e ilustrar con resultados propios aquéllas que son particularmente eficientes en el cultivo del garbanzo (Cicer arietinum L.).
EFECTO DE DÉFICIT HÍDRICO EN EL PATRÓN ELECTROFORÉTICO DE PROTEÍNAS TOTALES EN DOS VARIEDADES DE MAÍZ
Authors: Espinosa-Paz Néstor , Montiel-Aguirre Fernando , Rodríguez-Ontiveros José Luis
Published: November 2022

En el presente trabajo se analizo el efecto del déficit hídrico en los patrones electroforéticos de proteínas totales de la raíz, tallo y hojas de las variedades de maíz Criollo Cajete y Michoacán 21 Compuesto 1-104 cultivadas en campo e invernadero. El déficit hídrico inhibió y promovió la síntesis de unas proteínas, pero la expresión de otras no fue afectada. Los patrones electroforéticos fueron diferentes entre tratamientos hídricos, variedades y órganos vegetativos. Las dos variedades mostraron mayor número de bandas protéicas cuando fueron sembradas en invernadero que en campo y en cuanto a los patrones de la hoja, en invernadero no se observaron cambios. Las bandas de proteínas encontradas en este estudio bajo déficit hídrico son semejantes en su peso molecular a las reportadas en la literatura bajo las mismas condiciones.

Authors: López-Santillán José Alberto , Castro-Nava Sergio , J.-Huerta Alfredo
Published: November 2022

En un experimento efectuado durante 1992, se evaluó el efecto del temporal sobre la producción de ceras epicuticulares por hojas de cinco genotipos de sorgo (Sorghum bicolor L. Moench) en diferentes etapas fenológicas. Se muestrearon segmentos de hoja en etapa vegetativas (53 días después de la siembra, DDS), en antesis (68 DDS) y en llenado de grano (83 DDS), en las que se cuantificó la cantidad de ceras epicuticulares mediante un método colorimétrico. Se encontraron diferencias estadísticas (P<0.01) entre genotipos, entre etapas fenológicas y entre condiciones de humedad. En promedio, la concentración de cera aumentó en 21 % en la condición de temporal, en comparación con la de riego. Tal aumento de ceras epicuticulares fue superior en 64 % en la etapa de llenado de grano que en la etapa vegetativa. Se concluyó que el aumento de concentración de ceras epicuticulares en la lámina de hoja de sorgo, se da en respuesta al estrés hídrico, en magnitud que depende del genotipo y del grado de estrés.

Published: November 2022

Una población de 117 líneas endogámicas recombinantes (RILs) F6, derivada de la cruza de las variedades Frontana e INIA66, se analizó mediante el uso de marcadores moleculares para construir un mapa genético que servirá de base para determinar los QTL de caracteres que segregan en la población. Un segundo objetivo fue determinar el potencial conjunto de la utilización de dos tipos de marcadores: RFLPs y los microsatélites o secuencias simples repetidas (SSRs), en el análisis genético de una especie de genoma complejo, como el que posee el trigo harinero (Triticum aestivum L. em. Thell.). Los progenitores se analizaron con 822 sondas de RFLPs y 68 pares de iniciadores. Mientras que los RFLPs mostraron un nivel bajo de polimorfismo (29 %), los SSRs tuvieron una mayor capacidad de detección del mismo (40 %). El análisis de las 117 RILs con 158 sondas RFLPs y 27 SSRs permitió la formación de 26 grupos de ligamiento. La especificidad de los SSRs fue un factor importante para la correcta designación de los grupos de ligamiento. Los resultados muestran que la combinación de diferentes clases de marcadores es una mejor estrategia para superar la limitante del nivel bajo de polimorfismo detectado al utilizar exclusivamente marcadores RFLPs en especies como el trigo.

Esta propuesta es el resultado del análisis de la realidad del Ecuador en cuanto a pruebas psicométricas, evidenciando, que, en su mayoría, no presentan baremos apropiados para la población ecuatoriana. 
Por otro lado, calificar las evaluaciones con baremos no contextualizados al país, dan valores que no son completamente reales, y, esto, a su vez, da un informe que no es específico en cuanto a la función evaluada. Este proceso no es coherente con los requerimientos y normas que establece la toma de un test psicométrico y por ello se generan dificultades marcadas en la ejecución del test y los resultados obtenidos. 
Uno de los test más conocidos y utilizados en el área psicológica, específicamente en la neuropsicología, es el test de atención D2, este mide diferentes elementos esenciales y componentes claves que intervienen en la atención, y como parte del análisis, no tiene datos contextualizados ni baremos estructurados para la población ecuatoriana. Por esto, el siguiente estudio busca obtener datos normativos preliminares para la prueba de atención D2 en el Ecuador.

Provinsi Riau secara umum memiliki wilayah dengan kondisi tanah gambut dengan cakupan yang cukup luas di Pulau Sumatera yaitu ±4,04 jt Ha atau 56,1% dari jumlah lahan gambut di Pulau Sumatera. Pembangunan jalan raya yang berada diatas tanah gambut harus memperhatikan kondisi tanah dasarnya terlebih dahulu agar jalan yang dibangun dapat bertahan lama. Tanah gambut yang digunakan diambil dari Desa Sadar Jaya, Siak Kecil, Bengkalis, Riau dan akan distabilisasi dengan menggunakan abu batang jagung (ABJ) dan semen sebagai bahan campuran stabilisasi. Metode stabilisasi tanah merupakan salah satu cara yang sering digunakan untuk memperbaiki kondisi tanah asli dengan kuat dukung tanah yang kurang bagus menjadi lebih baik lagi. Variasi campuran yang digunakan yaitu 2% ABJ, 5% semen dan 4% ABJ, 10% semen. Masa waktu pemeraman yang digunakan 0, 4, dan 7 hari pemeraman. Nilai CBR tanah asli pada pemeraman 0 hari sebesar 13,33%, 4 hari sebesar 16,04%, dan 7 hari sebesar 16,88%. Untuk nilai CBR pada tanah campuran 2% ABJ, 5% semen pada masa pemeraman 0 hari sebesar 13,75%, 4 hari sebesar 18,63% dan 7 hari sebesar 19,80%.

Published: November 2022

This article presents a case study that provides assessment of access to the Irish healthcare system and the services it provides. We explore factors related to unmet heath care needs using recent survey data. Our approach is based on using support vector machines for building predictive models that analyse and measure those factors. The proposed methodology is novel for the domain. Following the behavioural model for access to medical care, we group factors into three categories: predisposing, enabling, and needs, and analyse each group. Experimental results show and measure the primary causes of imbalances and inequalities of treatment in the Irish healthcare system today.

Institutions of higher learning around the world are considering the use of technology as alternative methods of instruction. Mobile learning technologies and wireless networks are becoming increasingly popular tools of facilitating learning in higher education institutions. Mobile learning (or m-learning) has the ability to connect learners to information anytime and anywhere. While some studies have explored the challenges and the issues of implementing this technology, a majority have focused on acceptance alone. However, little research has been conducted to comprehend factors for sustainable deployment of m-learning in higher education. This study was conducted with the intention of identifying the factors that affect the deployment of m-learning, in order to propose and evaluate a sustainable model for mobile learning deployment in university education. Objective: The main objective of the study was to develop a deployment model for use of m-learning in HEI in Kenya. Another objective was to find out the factors that affect deployment of HEI. Methodology: The study adopted a mixed method of research design where both qualitative and quantitative approaches were used. The study was A survey was conducted with a total of 148 students and 28 lecturers. The findings of this study indicate that a conceptual framework and model clearly delineating pre and post-deployment processes can provide a roadmap for sustainable deployment of m-learning. Furthermore, Education Organization and schools can use the model for blending mobile learning with traditional learning using a planned approach to improve education and learning

Shear lag effect increase as we move away from the section thereafter, the effects becomes predominant especially for the unsymmetric structures. The force transmission between the structure and patch occurs through bond layer, via shear mechanism, invariably causing shear lag. In the present study, an attempt is made to correlate the average shear stress in the bond layer obtained using the Bhalla & Soh model (2004) & BSC(Bhatt Saxena Chaudhary) model. In BSC model overall deformation of the bond layer is considered. It is simplified model of the complex shear lag phenomenon as with force transmission among PZT (lead zirconate titanate) patch and host structure .PZT is one of the world’s most widely used piezoelectric ceramic materials. When fired, PZT has a perovskite crystal structure, each unit of which consists of a small tetravalent metal ion in a lattice of large divalent metal ions. PZT is used to make ultrasound transducers both for loudspeakers and microphones and other sensors and actuators, as well as high –value ceramic capacitors and FRAM chips. PZT is also used in the manufacture of ceramic resonators for reference timing in electronic circuitry. PZT has a high dielectric constant, ferroelectric, piezoelectric, & pyroelectric properties. The ideal properties of PZT have made its application to transducer, sensor and actuator devices ubiquitous. Piezoelectric ceramics, when mechanically activated with pressure or vibration, have the capacity to generate electric voltages sufficient to spark across an electrode gap. Piezoelectric energy harvester has good compression performance, fatigue resistance and waterproof performance. Piezoelectric effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. The word Piezoelectric is derived from the Greek piezein , which means to squeeze or press ,& piezo , which is Greek for “push”. The main advantage of BSC model is that it does not involve solving the complex differential equations. Shear stress distribution is practically independent of excitation frequency except near pressure. BSC model can be made use of for carrying out the preliminary design in structural control related problems.

A single-stage refrigeration system has a low Coefficient of Performance (COP), thus it becomes paramount to have cascade refrigeration systems when there is need to have an evaporator temperature that is below -25 oC. Heat absorbed (QE) in the evaporator of low temperature cycle of two-step cascade refrigeration systems is one of the two parameters that determine the COP of the lower temperature cycle of the two-step refrigeration systems which is also a function of the COP of the cascade refrigeration systems. This research aimed at modelling and optimizing QE of the lower temperature cycle of two-step cascade refrigeration systems using eco-friendly refrigerants. Thermodynamic of the cascade refrigeration systems was performed by varying seven operating parameters using refrigerants R-134a in the High Temperature Cycle (HTC) and R-23 in the Low Temperature Cycle (LTC). Heat absorbed in the evaporator of the lower temperature cycle (QE[LTC]) of the refrigeration systems was optimized using Half Factorial Design of Design-Expert 12.0.1. The influence of the evaporating temperature (TE,HTC), condensing temperature (TC,HTC), cascade temperature difference (ΔTCAS,DIFF), evaporating temperature (TE,LTC), superheating temperature (TSUP,LTC), sub-cooling temperature (TSUB,LTC), and refrigerant mass flow rate (ṁHTC) was investigated on the values of QE[LTC] of the refrigeration systems. The numerical QE[LTC] value is 14.183 while the measured value is 14.81.The study revealed that all the factors having interaction with TC[HTC] and TE[HTC] have a great influence on the value of QE[LTC].

The need for habitable and affordable shelter cannot be overemphasized but the high cost of components of shelter such as hollow sandcrete blocks, bricks etc. posed a challenge to our ability to access affordable and habitable shelter. Utilization of already discarded waste foundry sand (WFS) as eco-friendly construction material for production of hollow sandcrete blocks, will save cost and preserve our environment. In this study, impact of locally available waste foundry sand as partial substitute for sharp sand in production of hollow sandcrete blocks was investigated. Sharp sand was partially substituted with WFS at 0, 10, 20 and 30%. A mix ratio of 1:6 (ratio of cement to sharp sand) and a water-cement ratio of 0.5 were used. Hollow sandcrete blocks were subjected to compressive strength tests at 7th and 28th days as well as a water absorption test on the 28th-day. Outcomes of the research showed that an increase in the amount of WFS led to the loss of compressive strength across all curing ages, and that all sandcrete block samples including control samples did not satisfy the minimum 28th day strength requirement of 3.5 MPa stipulated for load-bearing hollow sandcrete blocks. However, block samples containing 0 and 10% of WFS can satisfactorily be used for the construction of non-load bearing walls since they meet the required minimum strength of 1.5 MPa at 28th day. It was also observed that increasing the quantities of WFS from 0 – 30% caused a corresponding increase in the water absorption for all the block samples although the recorded values did not exceed the recommended maximum of 12% except for samples containing 30% WFS. Conclusively, WFS has a negative impact on both compressive strength and water absorption properties of sandcrete blocks and as such cannot serve as a good partial substitute for sharp sand.

Location and its elements such as ease of accessibility, efficiency of movement in terms of cost and time taken are crucial in determining the performance and returns inherent in every commercial investment. As a result, the effects of location on the performance of event halls in Akure were investigated in this study. The study’s sampled populations were the 30 owners/managers of event halls in Akure which were stratified based on the income zones into low, medium and high income zones. Data were gathered using structured questionnaires and analysed using descriptive statistics, Trend and Regression Analysis. The findings revealed the price of the event halls in Akure varied between N 80,000 and N 300,000. The results also showed that the income zone, distance to road and capacity of the halls are statistically significant at p value ≤0.05 in affecting the performance of event halls in Akure. The study concluded that location is crucial in enhancing performance and recommended that investors should be encouraged to take into account the placement of the event halls, with a fundamental consideration of the income zone as it influences the performance of the event halls.
A Review on Students’ Housing in Nigerian Universities

Published: November 2022

Students housing in Nigeria Universities has witnessed several policy interventions, yet the challenges of deficit and satisfaction persist – requiring an overall review. This paper utilized a desktop review approach to collate and process secondary data which were sourced from published academic and governmental documents. It discovered that the challenges of student housing in Nigeria cannot be disconnected from the establishment of new universities and an increase in student admission to the universities – which affected funding. Unfortunately, the uncontrolled involvement of the private sector and full entrants of non-residential universities, rather than improving students’ housing, further magnified the challenges – as private investors are only interested in profits. The paper concluded by recommending increased funding, build, operate and transfer model for the development of hostels, and the introduction of student villages.

Authors: Garba H , Abiola A.
Published: November 2022

Water distribution systems are designed to adequately satisfy the water requirement for domestic, commercial industrial and firefighting purpose. A spatial database of the water distribution systems (WDS) for Hayin-Banki was created in a Geographic Information System (GIS) environment (ArcGIS), drawing inputs data from water supply and demand. Environmental Protection Agency Network (EPANET, 2.0) was used to analyze the WDS to explore its reliability in current and future scenarios. Mapping of the existing 12.270 km long distribution network revealed that the total length of ductile iron pipe (DIP) is 11.12 km and asbestos cement (AC) pipes is 1.15 km. Running the analysis identified supply gaps, which includes deficiencies in the distribution system (small diameters pipes, system losses) resulting to negative and very small pressures. Running simulations with EPANET and geospatial techniques was used to solve the identified deficiencies.

Conflict is inherent in construction projects due to uniqueness, complexity and involvement of several stakeholders. Occurrence of conflicts affects projects outcomes if not properly managed. This study assessed the influence of factors responsible for conflicts on time, cost and quality performance of construction projects. A quantitative approach which entails questionnaire survey was adopted. Data were collected through questionnaire administered to 125 construction professionals, out of which. 83 were properly filled and returned. The data collected was analysed using both descriptive and inferential statistics. Influence of the conflict factors on project performance parameters was ranked using mean and standard deviation. Kruskal-Wallis Test was used to determine the statistical significance of the variation in influence of the conflict factors on time, cost and quality performance of construction projects. Results indicated that the influence of all the 21 assessed conflict factors ranges from ‘moderate’ to ‘high’. 15, 13 and 13 factors have high influence on time, cost and quality performance respectively. Findings of the study also indicated that the variation in the influence of conflict factors on time, cost and quality performance of construction project was statistically not significant (p value obtained is 0.286 for P≤ 0.05). The study concludes that 13 conflict factors have high influence across time, cost and quality performance of construction projects. Furthermore, the influence of conflict factors on time, cost and quality performance of construction projects is similar. The study recommends that construction stakeholders should strive to minimise the occurrence of factors which give rise to conflict in any given project so as to achieve optimal project performance.

A Review on Outliers in IoT
Authors: Reddy Y. Harshavardhan , Srinivas M. Hari , Ali Adnan , Sha A. Zaheer
Published: November 2022

In recent decades, the Internet of Things (IoT) has grown rapidly, attracting the attention of scientists and businesspeople. In extreme conditions, autonomously scattered sensor nodes pose a high risk of failure and intrusion into the IoT, skewing sensor values. Abnormal data, anomalies, or outliers are sensor values that depart from norms. When abnormalities are factored into data analytics, the ultimate judgment is affected. Using data-driven algorithms for IoT outlier detection is a cutting-edge tactic in Machine Learning (ML). However, evaluating the effectiveness of implemented ML techniques for outlier detection in IoT, which have the minimal processing power and power sources to ensure data quality, raises several difficulties that have just recently begun to be addressed in the academic literature. This paper analyses the cutting-edge architecture, type, degree, technique, and detection mode of AI and statistical outlier detection strategies in IoTs. Also, each of the ways to find outliers is talked about in detail, along with ways to make them better.
