Authors: Luo Chengwen , Geng Cai-Zheng , Tung Yung-Hsien , Wang Bing-Long , Tung Tao-Hsin
Published: September 2022

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, has become a major public exigency of international concern. The COVID-19 epidemic has spread rapidly around the world, profoundly impacting people's lives. Patients are among those most affected by the pandemic. COVID-19 has adversely affected health-care systems, and the effects are long-lasting and devastating. Most medical institutions in the impacted countries and regions have been imbued with COVID-19 cases, both confirmed and suspected, leading to an overburdened health-care workforce like never before. While most of the critical situations involved internal medicine departments, such as infectious diseases, and intensive care units, other specialties, including dermatology, have also been profoundly affected by this pandemic. Dermatoepidemiology, the application of epidemiological methods to dermatology practice, is an important emerging discipline in dermatology. In this review, we discussed the influence of the COVID-19 epidemic on dermatology practice, as well as the application of public health strategies in dermatology. These findings from genetic epidemiological research, clinical trial networks, and pharmacovigilance research suggested that further research in dermatology requires collaborative studies across different fields, institutions, and countries. To solve the highly complex unsolved problems that we face, dermatologists and epidemiologists should be dynamic team members with multiple approach skills.

Published: September 2022

Purpose:

To compare different immobilization devices used for chest wall and nodal irradiation in breast cancer dosimetrically.

Materials and Methods:

All patients with left-sided breast cancer received chest wall and lymphatic irradiation. Treatment plans were created for radiotherapy in single arm (SA) lift board, double arm (DA) lift board, and wing board (WB) positions. Dose–volum e histograms (DVH) were used for evaluation based on planning target volume (PTV) coverage and organs at risk (OARs). One-way analysis of variance (ANOVA) test was performed to identify the dose–volume differences among different immobilization techniques.

Results:

Clinically acceptable plans were generated with all immobilization boards. Significantly lower doses in the body except target volumes were found in the SA lift board group compared to other groups (P < 0.05). No relevant differences were observed among the plans according to the other dose parameters of target volumes and OARs.

Conclusion:

SA board is an immobilization device that can be used safely for three-dimensional conformal radiotherapy in young left-sided breast cancer with an unfavorable anatomy as it significantly reduces low-dose exposure.

Introduction:

In any given population, coronary artery diameter is highly variables. It has been postulated that Indians have an increased risk of coronary artery disease (CAD) due to smaller diameter of arteries in them. However, small diameter can be due to smaller body surface area (BSA). Hence, we tried to assess whether smaller coronary artery dimensions in Indians are due to their smaller BSA or not.

Methodology:

In this observational study, patients undergoing computed tomography coronary angiography and having normal angiogram were included in this study. Patients' coronary artery diameters in major epicardial vessels were measured and indexed to BSA. Analysis was done to assess for any significance compared to Caucasians.

Results:

A total of 250 patients were part of this study. The mean diameters of proximal left main (LM), distal LM, left anterior descending (LAD), left circumflex (LCX), and right coronary artery (RCA) were 4.27 ± 0.78, 4.26 ± 0.79, 3.47 ± 0.6, 2.99 ± 0.64, and 3.33 ± 0.63 mm, respectively. On indexing to BSA, the measurements in proximal LM, distal LM, LAD, LCX, and RCA were 2.31 ± 0.4, 2.31 ± 0.4, 1.89 ± 0.32, 1.62 ± 0.35, and 1.81 ± 0.34 mm/BSA, respectively. When they were compared to other Indian and Caucasian studies, the diameters were not found to be statistically significant.

Conclusion:

Thus, the authors conclude that Indians do not have an increased risk for CAD because of their smaller diameters, but it is because of their smaller BSA. This study helped us evaluate the reference range of major epicardial vessel diameters in Indian population.
Broken Guidewire During Percutaneous Transluminal Coronary Angioplasty Retrieved Properly and Nightmare Became a Good Lesson and Experience
Authors: Mukherjee Sudeb , Paul Kaushik
Published: September 2022

Percutaneous transluminal coronary angioplasty is associated with less complications compared to the open surgical technique. Fractured guidewire inside coronary arteries is not common during the procedure. It should be removed with proper technique. Nonremoval of such fractured wire may pose several complications. Different techniques can be used to remove such fractured wires. Here, we have reported a case of such incidence and its removal successfully percutaneous safely.

Authors: Mahanta Dibyasundar , Singh Jogendra , Mahapatra Rudra Pratap , Barik Ramachandra
Published: September 2022

Left main coronary artery dissection induced by the tip of the guide catheter (Razor blade effect) with or without extension into the adjacent aortic wall can result in no flow. It is being a life threatening, complication and must be time timely detected and treated by stenting or surgery. A 59-year-old male patient presented with crescendo angina having a history of stenting to left anterior descending coronary artery (LAD) using 3 mm × 23 mm drug-eluting stent 5 years back. Coronary angiogram revealed 100% instent re-stenosis of the LAD. Left circumflex (LCX) coronary artery had proximal chronic total occlusion with J-CTO score of ≥2. The dominant right coronary artery was normal. LMCA dissection was noticed like an invisible dragon from nowhere after stenting of the proximal LCX followed by abrupt retrograde extension into aorta, resulting in no flow in the left coronary artery. The true lumen of LMCA was re-wired, and timely bailout stenting from LMCA to LCX was performed.
Current Concepts of Optical Coherence Tomography Assessment of Left Main Coronary Artery During Coronary Interventions
Authors: Kasturi Sridhar
Published: September 2022

Conventional angiography is poor in assessing type of plaque, plaque volume, disease extent, severity and features associated with optimization of percutaneous coronary intervention (PCI), whereas Intra-Vascular Ultra-Sound (IVUS) and optical coherence tomography (OCT) overcome these limitations by providing cross sectional images of vessel wall, and longitudinal extent of disease. OCT provides high-resolution images at the cost of limited penetration compared with IVUS with an axial spatial resolution of 10–20 μm versus 100–200 μm, lateral resolution of 20 μm versus 200 μm, and penetration depth 1–2.5 mm versus 10 mm, respectively. OCT measurements were proved to be nearer to the actual luminal areas whereas IVUS measurements were overestimated and were less reproducible in the phantom model. OCT and IVUS are proved to be a valid guidance for optimization of PCI. However, usefulness of OCT in day to day practice is very limited in the assessment of Left Main disease. Both imaging technologies have different distinct features, these are complementary and should be opted carefully for each patient based on pros and cons, and clinical indications of each technique.

Authors: Mba Chioma Judith , Yunusa Umar , Ibrahim Amina N. , Rajah Amina Suleiman
Published: September 2022

Midwifery practice has continued to gain recognition as a result of its influence on the health of mothers and newborns. However, the practice of midwifery in Nigeria is associated with numerous challenges leading to negative health indicators in the region. This paper examined the challenges associated with midwifery practice and education in Northern Nigeria with a view of exploring the way forward. Relevant literatures of stakeholders ’ reports and studies conducted globally and locally were searched and reviewed. Findings from the reviewed literatures showed that midwifery workforce is short of the ideal number required globally and specifically in Northern Nigeria. This shortage of midwives could be linked to the poor performance of Nigeria in achieving MDGs and now SDGs leading to outrageous Maternal Mortality Rate (MMR) in Northern Nigeria. Other highlighted challenges affecting midwifery practice and education in the region include; usurping of midwives’ roles/duties by doctors lack of comprehensive data on midwives, poor attitude of midwives, poor remuneration, negative patient’ s perception of midwives, feminization of midwifery profession and lack of resources and equipment. The paper therefore recommends that there should be continuous training of midwives as well as a need to review of the curriculum, code of ethics, scheme of service and entry qualification for midwives.
Adoption and use of open-source software in academic libraries in Ghana
Authors: Dei De-Graft Johnson , Tetteh Citizen Francis
Published: September 2022

The study sought to assess the adoption and use of open-sourced software (OSS) in academic libraries in Ghana, specifically, find out the types, user-friendliness, the extent of use, advantages, and limitations of OSS within the academic library domain. This study adopted the descriptive survey and mixed research approach to collect data from 12 academic libraries that have adopted open-source software for managing their resources. The purposive sampling strategy was adopted to select 10 respondents (comprising the head of libraries, head and staff of the IT units of the libraries, and heads of the other units such as electronic resources, cataloging, classification, and referencing, among others) from each of the 12 libraries. Questionnaires (consisting of both closed-ended and open-ended questions) were used to collect primary data directly from the respondents. The study revealed that Koha, DSpace, Destiny, NewGenLib, Evergreen ILS, Fedora, WordPress, and Drupal were the open-sourced software deployed and used in the libraries and provided lots of advantages to the libraries. The open-sourced software was largely found to be easy to acquire, install, update, modify, use, operate; user-friendly; and more reliable and accessible. However, the use of open-sourced software in the libraries is mitigated by some limitations which include lack of continuous training on the use of the open-sourced software and inability of the open-sourced software; lack of expertise to train and manage the software among others. These limitations need to be addressed to alleviate their negative impact on the library. The research focused on the adoption and use of OSS in academic libraries in Ghana. Although the findings of the study are similar to perceptions and practices from researchers around the world, they can not be used as a basis for generalization across other scientific disciplines and settings. The study concludes that the deployment and use of OSS in academic libraries to manage its processes and functions are speedily changing the frontiers of the libraries. It is relevant in achieving optimal efficiency at a minimal cost in the library. The management of the libraries should put measures and policies to realize these benefits and arrest the challenges faced by the use of OSS.

Authors: Ezeani E.U. , Ngobiri N.C. , Agbagwa I.O.
Published: September 2022

The efficacy of bio-stimulants on the remediation of hydrocarbon polluted soil was assessed using Gas Chromatography with Flame Ionization Detector (GC-FID). The enhanced bio-stimulants were discarded melon pulps, discarded breadfruit pulps and poultry droppings. These were applied to the polluted soil in the ratio of 1:5; the blend was observed for sixty days. Inferring from the chromatographs, the carbon compounds present in the polluted and remediated soils ranged from C12 – C40 with varying concentrations; C12 to C19 were dominant, C9 to C11 were residual with negligible concentrations. The total petroleum hydrocarbon (TPH) of polluted soil was 42,229.73 mg/kg, and the remediated soils were: biodegraded melon pulp - 23,786.3 mg/kg, biodegraded breadfruit pulp - 15,322.82 mg/kg, and chicken droppings, - 7,314.29 mg/kg. The results indicated that TPH of the polluted soil was reduced by 43.67% in sample remediated with biodegraded melon pulp, 63.71% in sample remediated with biodegraded breadfruit pulp, and 82.67% in sample remediated with chicken droppings. Therefore, a decreasing order of the effectiveness of the bio-stimulants is thus: chicken droppings > biodegraded breadfruit pulp > biodegraded melon pulp. The higher remediation potential of poultry droppings is attributable to high nitrogenous content. The study showed that the aforementioned bio-stimulants are effective in remediation of petroleum polluted soil. GC-FID detected the hydrocarbon present and their concentrations in the polluted and remediated soils. GC-FID is preferred to other analytical techniques due to its precision in identification and quantification of hydrocarbon fractions.

Authors: Charles Gameti , Afrifa Acheampong Akwasi , Ayer John
Published: September 2022

Processing of Global Navigational Satellite System (GNSS) data forms the basis for the usage of differential systems for obtaining spatial data. All open sources or commercial software packages developed for data processing give specific details to suit the intended purpose of the software. To obtain a uniform format for submitted survey data, Survey and Mapping Division (SMD) in various jurisdictions have specified formats for data submission for all kinds of surveys. In this regard, “GNSS Ghana” Software (GGS), a GNSS standalone Windows-based application with a modern user-friendly interface was developed for geodetic applications such as, projection and datum transformation worldwide, GNSS data post-processing of Receiver Independent Exchange Format (RINEX) files, and generating reports to meet Ghana SMD reporting standards including cadastral computations and reports for submission. To assess the developed software, GNSS data from two International GNSS Service (IGS) stations (BJCO and YKRO) were processed using GGS and three other commercial software such as GNSS Solution Software (GSS), Spectrum Survey Software (SSS), and Leica Geo Office (LGO), and the positional results compared against the existing coordinate. The results revealed that the GGS outperformed the remaining three commercial software packages with a sub-meter level of accuracy. Further assessment was conducted on datum transformation using the coordinates of 21 existing geodetic control points in Ghana. Utilizing the 7-transformation parameters of Ghana, the results gave uncertainties of [0.10ft. ± 0.99ft.] in the eastings and [0.02ft. ± 1.61ft.] in the northings with a 99% confidence level.

Published: September 2022

We present the measurement of fractures near the town of Beaufort West, South Africa. A field visit was conducted to examine the dip and azimuth of rock outcrops in and around the town. The locations of these various fractures were mapped and their orientation, which included the dip and strike of the rock surface, was measured using a geological compass (i.e., Brunton Truarc 15 Compass). The geological compass measurements were then compared to three mobile devices. These mobile devices, namely an iPad 2 and two smartphones (Samsung S8 and Huawei P10 Lite), all had the same application for standardization and the mobile device results were individually compared to the geological compass. The data stemming from the various mobile devices and the geological compass were then compared in terms of their variance. This statistical analysis was performed using the Correlated T-test method, as well as the Pearson Correlation Coefficient formula. To visually examine the main fracture orientations, the data obtained using the geological compass was plotted on a rose diagram. Results show that the relationship between the geological compass and the mobile device readings had little to no correlation, when using both the correlation and t-tests as combined determinants. This highlights the importance of ensuring measurement accuracy in the field as well as instrument calibration in situ.

Published: September 2022

Uromycladium acaciae, also known as wattle rust, is a rust fungus that has adversely impacted black wattle (Acacia mearnsii) in South Africa. This study assessed the potential of the Landsat 8 multispectral sensor to detect canopy damage caused by wattle rust on two plantation farms near Richmond, KwaZulu-Natal. The Landsat 8 bands and vegetation indices detected forest canopy damage caused by Uromycladium acaciae with an accuracy of 88.24% utilising seven bands and the Partial Least Squares Discriminate Analysis (PLS-DA) algorithm. Additionally, the model was optimised using the Variable Importance in Projection (VIP) method which only selected the most influential bands in the model. The coastal aerosol band (430nm-450nm), red band (640nm-670nm), near infrared (850nm-880nm) and NDVI were exclusively used in the optimised model and an accuracy of 82.35% was produced. The study highlighted the potential of remote sensing to detect canopy damage caused by a rust fungus and contributes towards a monitoring framework for analysing trends using freely available Landsat 8 imagery

Published: September 2022

Information on deformation of the land surface is vital for planning of infrastructure especially in areas such as the Albertine graben with substantial amounts of oil discoveries. Traditionally, global positioning systems, precise leveling and geotechnical techniques have been used for assessing and monitoring ground deformations. While these techniques provide accurate information, they are point based, expensive, time consuming and labour intensive over large area monitoring. This study explored an interferometric synthetic aperture radar (InSAR) approach for mapping deformation over Buliisa oil discovery area located in the Western arm of the East African rift valley. The method was implemented by measuring the phase differences of ALOS PALSAR data acquired between 2007 and 2011. Deformation estimates varied between -0.45m to +0.34m while the mean displacements varied from –0.10m to 0.089m. High ground deformation was detected in the Southern, North Eastern and North Western parts contributed by agricultural activity and drilling pad constructions. Generally, analysis of ALOS PALSAR data using InSAR approach provides a viable option for assessing land surface deformation in Buliisa oil exploration area.

Published: September 2022

Invasive alien plants (IAPs) are responsible for loss in biodiversity and the depletion of water resources in natural ecosystems. Prosopis species are IAPs previously introduced by farmers to provide shade and fodder for livestock. In the Northern Cape, Prosopis spp. invasions are associated with the loss of native species resulting in overgrazing and degrading rangelands. Mapping Prosopis glandulosa is essential for management initiatives to assist the government in minimising the spread and impact of IAPs. This study aims to evaluate the performance of two machine learning algorithms i.e., Support Vector Machine (SVM) and Random Forest (RF) to map the spatial dynamics of P. glandulosa in Prieska. The spatial invasion extent of P. glandulosa was mapped using multitemporal Landsat data spanning the period from 1990 to 2018. Validation of the results was done through an estimated error matrix with the use of the proportion of area and the estimates of overall accuracy, user’s accuracy and producer’s accuracy with a 95% confidence interval. The performance of the SVM and RF classifiers showed similar results in the overall accuracy and Kappa statistics throughout the years. These methods showed an overall increase of at least 3.3% of the area invaded by P. glandulosa from 1990 to 2018. The study indicates the importance of Landsat imagery for mapping historical and current land cover change of IAPs. The spread of P. glandulosa was confirmed by an increase in the total area of invasion, which enables decision-makers to improve monitoring and eradication initiatives.
Modelling the effect of terrain variability in even-aged Eucalyptus species using LiDAR-derived DTM variables
Authors: Munsamy Roxanne , Gebreslasie Michael , Peerbhay Kabir , Ismail Riyad
Published: September 2022

Accurate multi-source forest inventory attributes are necessary for estimating productivity and timber stock in commercial forest plantations. This study aims to uncover the effects of terrain variation on the growth of even aged Eucalyptus forest species using Light Detection and Ranging (LiDAR) topographical variables. Using 32 generated variables at 5 different spatial resolutions (1m, 3m, 5m, 7m, 9m), the random forest (RF) regression successfully revealed variations for structural attributes such as volume (Vol/ha), dominant tree height (HtD), mean tree height (Htm), and diameter breast heights (DBH). Results indicate that smaller spatial resolutions performed better for younger stands while larger resolutions produced the best results for mature stands. Using the multi-resolution approach results improved with variable selection. Incoming solar radiation and slope variables were among the most important terrain variables for modelling forest structural variability. The findings from this study demonstrates the value of stratifying forest productivity across the commercial forest landscapes of South Africa.
Comparison of gross morphological and histological features of placenta between hypertensive and normotensive pregnant women attending Muhimbili National Hospital.
Authors: Furaha Antpas , Russa Dennis
Published: September 2022

Background: Placenta is the vital fetomaternal organ that is responsible for the maintenance of the pregnancy and promotion of fetal growth and development. The optimal survival, growth, and development of the fetus correspond to the appropriate formation and development of the placenta. Hypertensive disorders of pregnancy exert a great impact on the placenta and reflect changes both morphological and histological.

 Objective: To compare the morphological and histological features of the placenta between hypertensive pregnant mothers and non-hypertensive pregnant mothers who attended Muhimbili National Hospital (MNH).

Methods: A hospital-based cross-sectional study was conducted from June 2020 to August 2020 at Muhimbili National Hospital (MNH).  A total of 80 placentas were studied morphologically and histologically, of which 40 placentas were from hypertensive pregnant mothers and 40 placentas were from normotensive pregnant mothers. In the morphological aspect shape, weight, the site of insertion of the umbilical cord, the number of cotyledons of each placenta and thickness of the placenta were noted. In the histological part, Neutral buffered formalin (NBF) was used the routine staining technique which was Hematoxylin and Eosin (H&E) and a light microscope was used. The data were analyzed by using SPSS version 20 computer software and the results were summarized in means and proportions. ‘T-test’ and chi-square’ tests were used and the difference was statistically significant when the p-value>0.05

 

Results: The irregular shape of the placenta and marginal insertion of the umbilical cord were more in the hypertensive group and were statistically significant (p>0.01). The mean placenta weight, mean placenta thickness and mean numbers of cotyledons were significantly less in a hypertensive group compared to the normotensive group (p<0.01). A microscopic study of the placenta revealed the presence of fibrinoid necrosis, syntial knots, calcifications and villous hypoplasia in both normotensive and hypertensive group however these findings were significantly higher in the hypertensive group (p>0.01).

Conclusion: Hypertensive disorders of pregnancy (HDP) exert a profound impact on the placenta. Morphologically altering its dimensions and histologically fibrinoid necrosis, calcifications, syntial knots, and villous hypoplasia were significantly more in the hypertensive group than in the normotensive (p>0.01).

Nanyin village is a malaria endemic area consisting of Bunmouk Township Sagaing Region in Myanmar. Ohnpinkone and Bwedarkone wards were chosen for measuring vector bionomics, potential vectors, susceptibility and bio-efficacy of long lasting insecticidal nets (LLINs) (due to high prevalence of P. falciparum) in both wards from December 2019 to October 2020. A total of 3236 and 3019 Anopheles mosquitoes consist of 12 species were collected from both Ohnpinkone and Bwedarkone wards. Anopheles barbirostris was found highest number (1088 and 820) followed by An. philippinensis (267 and 605) in both areas. Higher number of Anopheles mosquitoes were collected by Cattle bait catching method followed by Indoor Light traps method. The highest was collected in October in Ohnpinkone and September in Bwedarkone. In Ohnpinkone, the highest was collected in April by outdoor and August in indoor light trap and March by outdoor and June by indoor light traps in Bwedarkone. Higher number of main vectors of An. minimus and An. dirus were collected in Ohnpinkone than Bwedarkone and highest number of An. minimus was collected by cattle bait (77) followed by indoor light method (72) in Ohnpinkone. Only 11and 3 An. dirus were collected, of this 9 and 1 number were collected by indoor light traps method from both wards. One An. minimus from Ohnpinkone was found sporozoite positive (0.47%). Main vector An. minimus was collected highest in April in Ohnpinkone and June in Bwedarkone. Susceptibility status of primary and secondary vectors were found susceptible to Pyrethroid insecticides. Bio-efficacy of all tested LLINs nets were found lower efficacy 20% and 63.33% in both wards. Main vector of An. minimus was collected year round in large number in both areas as well as sporozoite positive and An. dirus was available in both areas. Therefore, both areas are highly malaria risk areas and need to proper treatment and control measure using RIS and supply new LLINs nets or retreatment with deltamethrin to old nets according to WHO guideline to ovoid malaria transmission.

Manuela García-Teruel Manso, una señorita decimonónica en el billete mexicano: género y formas simbólicas materializadas
Authors: Castelli Olvera Azul Kikey
Published: September 2022

Analizar desde la hermenéutica, el contexto sociohistórico de la imagen de la poblana Manuela García-Teruel Manso impresa en los billetes mexicanos de finales de siglo XIX, desde la perspectiva de género y el concepto de forma cultural material. Se retoma la propuesta de análisis hermenéutico de J. B. Thompson que se subdivide en tres categorías: análisis sociohistórico, análisis formal y análisis interpretativo, centrándose en la primera, la cual comprende: escenarios espacios temporales, campos de interacción, instituciones sociales, estructura social y medios técnicos de transmisión. Los billetes pueden considerarse como una forma cultural materializada, en ellos se reiteran formas simbólicas interiorizadas, permeadas por la ideología política, cultural, religiosa y por supuesto, de género. Por lo anterior, en los billetes se reiteró la imagen idealizada de la mujer porfiriana en la impresión se perciben la idea romántica de la belleza y la virtud, mezcladas con la estética romántica y modernista que trajo consigo reiteraciones de lo mítico, lo tecnológico y lo nacional. Aunado a lo anterior, también se detecta lo que podría denominarse, desde los conceptos actuales, como violencia simbólica por la forma en la que la imagen llegó a los billetes y por la invisibilización histórica del personaje femenino.

La inclusión de los cuidados en el diseño de las ciudades para disponer del equipamiento suficiente y accesible que permita atender el derecho a cuidar y ser cuidado sigue siendo un desafío. En México se han logrado avances sobre este derecho, pero no son suficientes ya que son logros locales o muy generales. Esta investigación toma como referente el crecimiento urbano en el Estado de México, a partir de la producción masiva de vivienda a través de la figura de conjuntos urbanos, los cuales se presentan como una unidad espacial integral, más allá de la simple producción de vivienda. El objetivo de este artículo es presentar una caracterización del equipamiento para los cuidados en un conjunto urbano de interés social y popular del municipio de Zumpango, perteneciente a la Zona Metropolitana del Valle de México. Metodológicamente, se llevó a cabo una investigación documental, teórica y de documentos oficiales, procediendo de manera deductiva para contextualizar el objeto de estudio, esto es, el equipamiento para los cuidados. También, se utilizó el Censo de población 2020, y para la investigación de campo se realizaron recorridos dentro del conjunto urbano. Los resultados se presentan con un análisis descriptivo. Dentro de los hallazgos se encontró que, si bien este conjunto urbano se podría considerar como propositivo en cuanto a equipamiento para los cuidados, éste se enfoca predominante hacia la niñez, dejando fuera a otras poblaciones, principalmente a las personas mayores, denotando una planificación a corto plazo.

Published: September 2022

Concrete is one of the most widely used building materials throughout the world. Concrete is used in large amounts because it is an extremely good building material. In many places of the world the temperature is rising day by day. These days due to constant sand mining the natural sand is depleting at an alarming rate. In this case, fine aggregate is partially replaced by magnetic sand. In this present study, an attempt has been made to study the mechanical properties of M₂₅ grade concrete with a different percentage at a range of 10%, 15% and 20% as partially replaced with magnetic sand to the total weight of fine aggregate. It has been experimented that the required strengths are achieved the optimum percentage of magnetic sand by conducting compressive strength and flexural strength of concrete. Use of magnetic sand in concrete, will enhance shrinkage and crack resistance and reduce the environmental impact and also reduce the cost. The compression and flexural strength of concrete increases with various percentage replacements of magnetic sand. The main aim of this study is to make economical and eco-friendly concrete.

Authors: Srinivasan J. , Sathiyamoorthy A.
Published: September 2022

Reinforced concrete beam members are load-carrying members in structures. The beams performance is largely depending on the condition of the tensile reinforcement in members and quantity in the beam. Focus is put on flexural strengthening, which currently is the most common application field for composite materials in structural engineering. Generally, pre-stressed FRP will be demonstrated to follow the principle of conventional pre-stressed concrete by resulting in higher cracking, yielding, and bearing loads. Especially under service loads, the structural behavior is improved. Civil structures in several situations require strengthening of the structural members due to lack of stiffness, strength, serviceability, durability. Some situations where the members are in need of rehabilitation in their lifespan. There are many situations where the requirement of strengthening is must for structures such as Retrofit for seismic effected building

Las teorías dominantes en la gestión estratégica consideran que la ventaja competitiva es el desempeño de la empresa, mientras que la oposición afirma que es la capacidad de las empresas para lograr un desempeño superior. Esta última afirma que la ventaja competitiva podría determinar el desempeño de la empresa, pero que muchos otros factores pueden modificar la relación. El propósito de este estudio fue analizar la importancia de la ventaja competitiva y el desempeño empresarial en el contexto de las pequeñas y medianas empresas en México. Sellevó a cabo desde un enfoque cualitativo, con un alcance descriptivo a través de una profunda revisión bibliográfica. En el caso mexicano, la ventaja competitiva de las pequeñas y medianas empresas se ha visto afectada negativamente por la falta de acceso a financiamiento, fallas administrativas, rezago tecnológico y falta de mano de obra calificada, lo que afecta negativamente su desempeño.Por lo tanto, los resultados de la investigación han demostrado que el capital humano, la innovación, la tecnología de procesos, la planificación estratégica, la productividad, el aseguramiento de la calidad, la gestión de la cadena de suministro y la adaptabilidad juegan un papel crucial en la competitividad y el éxito del sector empresarial estudiado.
