Published: January 2023

Pada tahun 2012 Proyek Pengembangan Air Tanah (P2AT) Jawa Timur membangun sumur bor SDMJ 552 agar kebutuhan air irigasi di Desa Purwojati Kabupaten Mojokerto terpenuhi. Walaupun sudah dibangun sumur pompa seperti SDMJ 552, kurangnya sistem pengoperasian yang tepat menyebabkan sumur tersebut beroperasi kurang optimal, untuk menghindari mangkraknya SDMJ 552 pada studi ini akan dilakukan penilaian kinerja jaringan irigasi air tanah. Penilaian ini akan mencakup penilaian teknis dan non teknis berdasarkan parameter yang tercantum pada Permen PUPRÂ No.12/PRT/M/2015. Aspek teknis yang dinilai meliputi kinerja pra sarana fisik dan sarana penunjang SDMJ 552, dimana dinilai dengan metode observasi/pengamatan di lapangan, mengukur efisiensi dari saluran irigasi, kemudian menilai produktivitas tanaman dengan menilai faktor K, realisasi luas tanam, pemenuhan kebutuhan air, produktivitas padi palawija dan nilai panen. Selain itu, wawancara akan dilakukan kepada petani terkait dengan Perkumpulan Petani Pemakai Air (P3A) untuk penilaian dari aspek sosial. Hasil penilaian indeks kinerja pada aspek teknis SDMJ 552 didapatkan nilai 87,78% untuk prasarana fisik yang termasuk dalam kategori baik dan dibutuhkan pemeliharaan secara berkala, sedangkan didapatkan nilaiÂ 40% untuk sarana penunjang dengan kategori buruk dan dibutuhkan perbaikan atau pengadaan komponen yang belum ada. Selain itu pada aspek ekonomi didapatkan nilai sebesar 89,6% untuk produktivitas tanaman dengan kategori sangat baik dan perlu dilakukan peningkatan sistem pemberian air agar produktivitas semakin optimal. Selanjutnya dari aspek sosial didapatkan nilai 49% dengan kategori buruk dan dibutuhkan upaya peningkatan kerjasama antar petani pemakai air dalam pengelolaan jaringan irigasi air tanah SDMJ 552.

Published: January 2023

Daerah Aliran Sungai (DAS) Pekalen yang terletak di wilayah administrasi Kabupaten Probolinggo, Provinsi Jawa Timur bermuara di Selat Madura dan bersumber dari Gunung Argopuro dan Gunung Lemongan yang mempunyai luas wilayah sekitar 1.696,17 km2 . Penyebab terjadinya banjir di Probolinggo pada tahun 2018 dan 2019 kemungkinan dikarenakan banyak terjadi penebangan pohon di hulu DAS Kali pekalen yang didominasi pohon sengon pada hutan masyarakat, selain juga diduga akibat perubahan tata guna lahan. Dengan adanya kejadian tersebut, maka diperlukan kajian erosi DAS Pekalen Hulu dengan outlet Bendung Pekalen serta meninjau tingkat bahaya erosi dan arahan rehabilitasi lahan dan konservasi tanah (ARKLT). Penelitian ini dilakukan dengan menggunakan metode USLE dan MUSLE, kemudian dibandingkan untuk mengetahui besarnya debit limpasan permukaan dan erosivitas di DAS Pekalen hulu, laju erosi, tingkat bahaya erosi, dan arahan rehabilitasi lahan dan konservasi tanah yang sesuai dengan kondisi DAS. Berdasarkan hasil analisis diketahui bahwa curah hujan rancangan periode ulang 1.01 dan 2 tahun masing-masing 82,27 mm 122,74 mm, dan total debit limpasan sebesar 48,35 m3/dt dan 72,13 m3/dt. Erosivitas hujan rata-rata tahunan Stasiun Hujan Condong sebesar 511,09 kJ/ha/tahun, Kertosuko 951,46 kJ/ha/tahun, Segaran 953,02 kJ/ha/tahun, dan Tiris sebesar 1069,86 kJ/ha/tahun. Erosi lahan metode USLE diperoleh sebesar 89,79 ton/ha/tahun, dengan SDR (Sedimen Delivery Ratio) menurut rumus Boyce, 1975 sebesar 11,72 % sehingga didapatkan SY (Sedimen Yield) sebesar 10,52 ton/ha/tahun. Erosi MUSLE dengan periode ulang 1.01 tahun rata-rata sebesar 5,75 ton/ha/tahun,untuk periode ulang 2 tahun rata-rata sebesar 9,03 ton/ha/tahun. Tingkat bahaya erosi didominasi oleh harkat erosi sangat tinggi dengan luas wilayah 6.693,08 ha (39,74 %), harkat erosi sedang dengan luas wilayah 5.051,82 ha (30 %), harkat erosi tinggi dengan luas wilayah 2.653,15 ha (15,75 %), dan harkat erosi rendah dengan luas wilayah 2.443,46 ha (14,51 %). Jadi dapat disimpulkan bahwa DAS Pekalen Hulu didominasi erosi sangat tinggi sebesar 39,74 %. Pola ARLKT yang dilakukan adalah memberikan kebijakan arahan penggunaan lahan yaitu, Kawasan Lindung dengan luas 5.094,76 ha (30,25 %), Kawasan Penyangga dengan luas 10.092,43 ha (59,93 %), dan Kawasan Budidaya dengan luas 1.654,31 ha (9,83 %).

Design Issues in Personalized Nutrition Advice Systems
Authors: de Hoogh Iris M , Reinders Machiel J , Doets Esmée L , Hoevenaars Femke P M , Top Jan L
Published: January 2023

The current health status of the general public can substantially benefit from a healthy diet. Using a personalized approach to initiate healthy dietary behavior seems to be a promising strategy, as individuals differ in terms of health status, subsequent dietary needs, and their desired behavior change support. However, providing personalized advice to a wide audience over a long period is very labor-intensive. This bottleneck can possibly be overcome by digitalizing the process of creating and providing personalized advice. An increasing number of personalized advice systems for different purposes is becoming available in the market, ranging from systems providing advice about just a single parameter to very complex systems that include many variables characterizing each individual situation. Scientific background is often lacking in these systems. In designing a personalized nutrition advice system, many design questions need to be answered, ranging from the required input parameters and accurate measurement methods (sense), type of modeling techniques to be used (reason), and modality in which the personalized advice is provided (act). We have addressed these topics in this viewpoint paper, and we have demonstrated the feasibility of setting up an infrastructure for providing personalized dietary advice based on the experience of 2 practical applications in a real-life setting.
E-learning Skills’ Impact on Teachers’ Performance in Higher Technical Teachers’ Training College of the University of Buea, Cameroon
Authors: Lyonga Ngemunang Agnes Ngale
Published: January 2023

The aim of this study was to evaluate the effect of E-learning skills on the performance of teachers in HTTTC Kumba. It was hypothesized that E-learning skills have no significant effect on teachers’ performance in HTTTC Kumba. A sample of 42 respondents was obtained by multistage sampling and administered a questionnaire to. The data were analyzed using frequencies and percentages for descriptive statistics, while the Chi-Square Test was used for testing the hypothesis. The results revealed that teachers in HTTTC Kumba are aware of E-learning and E-learning tools and are also of the opinion that the use of E-learning tools can improve performance, but they do not use E-learning platforms, nor do they believe that their students are better at E-learning platforms than in their traditional classrooms. It was recommended that education stakeholders should put all hands on deck to ensure a smooth integration of E-learning tools into the classroom.
Teaching Vectors to Junior Secondary School Learners: A Comparison of Two Approaches
Authors: Chirume Silvanos
Published: January 2023

The purpose of this study was to investigate whether Form 2 learners taught using the position and movement approach (Experimental group) performed better in a test on Vectors than their counterparts taught using the non-geometric or matrix approach (Control group). A comparison of the two approaches in relation to the Gestalt and the Behaviourist learning theories was also discussed. The mixed research approach (QUANT- Qual) was used. For the QUANT part, the quasi-experimental approach involving the pre-test – post-test control group design with 50 randomly chosen learners (25 in each group) was used. Results showed that, generally, the Experimental group performed better than the Control group, although the findings could be taken with caution due to the small sample sizes and the lack of a true experiment. For the Qual approach, four learners were purposively sampled. The learners were asked to talk about their experiences and performances during learning. An attempt to relate these experiences with the Gestalt and Behaviourist learning theories was also made. It could be concluded that the position and movement approach fitted quite well with the Gestalt Theory, whereas the matrix approach fitted with Behaviourism. These results and findings could help to inform the theory and practice of teaching Vectors in particular and other Math topics in general. There is also a need for further research to see if consistencies in these views could be established.

Authors: Saleem Balindi Shakir , Saleh Khidhur Khidhur
Published: January 2023

Objectives: The study designed to compare outcomes and morbidities in patient undergoes multi tracts percutaneous nephrolithotomy (PCNL) versus single tract PCNL.

Methods: From October 2019 to September 2020, 50 patients were prospectively investigated at Azadi Teaching Hospital and Vajeen Private Hospital in Duhok, Iraq. Group A included 25 patients who received single tract PCNL while group B had 25 patients who underwent multiple tract PCNL. Complex renal stones are treated with single or multiple tract PCNL depending on stone configurations and urinary system architecture utilising Guy's stone score. Laboratory and imaging data were correlated with stone size, stone-free rate, mean haemoglobin decrease, operation time, hospital stay, and postoperative problems.

Results: 64% of cases are male and 36% are female. The mean stone size in Group A was 3.3 cm (ranges 2.0 - 4.9 cm), but in Group B it was 5.1 cm (ranges 3.3 - 7.4 cm), which is substantially bigger. Group A's mean operational time was 64.4 minutes (ranges from 30-115 minutes), which is statistically significant compared to multiple tracts' 80.2 minutes (ranges from 45-120minutes). The decline in mean hemoglobin between the two groups is statistically significant. Group A and B had 8% and 12% blood transfusions, which is not significant. Group A had a mean hospital stay of 28.2 hours (20-48 hours), whereas group B had 40.8 hours (ranges 24-96 hours). In group A, 16% of patients experienced post-operative fever, whereas in group B, 20% did. 84% of single tract PCNL and 88% of multiple tract PCNL were stone-free.

Conclusion: Complex renal stones treated by multiple tracts PCNL; is efficient and safe with acceptable postoperative outcomes and complications in comparison to single tract PCNL.
Variation on a Theme: Demographic Patterns of Nuestra Señora de los Reyes Yapeyú Mission (Corrientes, Argentina)
Authors: Jackson Robert Howard
Published: January 2023

Several generations of scholars have accepted general assumptions about indigenous demographic patterns in the Americas after 1492 suggested by scholars such as Alfred Crosby and Henry Dobyns. According to this model, waves of epidemics spread across the Americas in outbreaks that claimed the lives of millions of people, but over time the indigenous populations built up immunities to pathogens such as smallpox and recovered. The analysis of demographic patterns of the Jesuit missions among the Guaraní challenges these assumptions. The mission populations experienced catastrophic mortality, which in some cases was more than 50 percent of the population of a given community several centuries following first sustained contact, and epidemics occurred about once a generation after there was a large enough pool of potentially susceptible hosts born since the previous outbreak. The case study ofYapeyú mission highlights the reality of considerable variation in levels of epidemic mortality between communities. For some 50 years, the mission did not suffer catastrophic epidemic mortality, as did neighboring mission communities.
La Real Cédula de 1781 y la disputa por el control de los protectores partidarios en la Intendencia de Trujillo
Authors: Zegarra Moretti Carlos Benjamín
Published: January 2023

El artículo analiza las luchas por controlar la protectoría partidaria en las últimas décadas del periodo virreinal. En estas disputas la Real Cédula del 11 de marzo de 1781, que otorgó a los fiscales protectores la exclusividad de nombrar a los protectores de partidos, ocupa un lugar de interés, ya que cambió el funcionamiento de esta institución en aspectos formales y en su rol de mediación en la sociedad. En algunos casos, grupos de poder local expresaron una aparente conformidad con los nombramientos, mientras que en otros plantearon una férrea oposición. El estudio de estas alianzas, que podían ser integradas por subdelegados, cabildos de naturales y comerciantes españoles, revela, en el caso de la Intendencia de Trujillo (Perú), que la protectoría partidaria podía quedar fuertemente limitada.

Published: January 2023

Objective Delirium has been reported in all the course of
COVID-19, especially in aged patient with severe SARS-CoV-2 infection,
but there are few studies on these millions of patients with none-severe
omicron infection. To study the incidence of delirium and its factors in
hospitalized elderly patients with non-severe Omicron infection，we
reported this single-center observational study. Methods
Patients tested positive for SARS-CoV-2 infection at the hospital were
included. We used the 3-min diagnostic Confusion Assessment Method for
delirium diagnosis. We collected the demographic data, medical history,
number of vaccine doses against COVID-19, the first laboratory tests and
chest computed tomogram, days to the outcome, and medications to treat
COVID-19. Results The data of 311 patients were analyzed, of
whom 73 (23.47%) patients were diagnosed with delirium. The five
parameters identified as independent factors for delirium were age, body
mass index, total protein, albumin-to-globulin ratio, and platelet-large
cell ratio. These parameters were used to create a risk prediction
model, which showed good predictive accuracy. A decision curve analysis
was made, using this model, patients could benefit from the treatment
with the incidence from 0.15 to 0.5. Conclusion we found that
delirium is frequently seen in elderly patients with non-severe Omicron
infection. Age, body mass index, total protein, albumin-to-globulin
ratio, and platelet-large cell ratio were identified as independent
factors for delirium. These factors are good for delirium, and early
detection and preventive action may be taken based on them.

Authors: Arosemena Marilyn , Salguero Maria V. , Naylor Rochelle N. , Wroblewski Kristen , Tasali Esra , Philipson Louis H.
Published: January 2023

OBJECTIVE

To examine sleep patterns in adults with maturity-onset diabetes of the young (MODY).

RESEARCH DESIGN AND METHODS

Adults with glucokinase (GCK)-MODY and transcription factor (TF)-related MODY (HNF1A, HNF1B, HNF4A) were recruited (n = 24; age 46.0 years, 79% women, BMI 24.7 kg/m2) from The University of Chicago’s Monogenic Diabetes Registry. Sleep patterns were assessed by 2-week wrist actigraphy (total 315 nights), one night of a home sleep apnea test, and validated surveys.

RESULTS

Overall, compared with established criteria, 29% of participants had sleep latency ≥15 min, 38% had sleep efficiency ≤85%, 46% had wake after sleep onset >40 min, all indicating poor objective sleep quality. Among all participants, 54% had a sleep duration below the recommended minimum of 7 h, 88% reported poor sleep quality, 58% had obstructive sleep apnea, and 71% reported insomnia. Compared with GCK-MODY, participants with TF-related MODY had poorer objective sleep quality and increased night-to-night variability in sleep patterns.

CONCLUSIONS

Sleep disturbances appear to be common in adults with MODY despite absent traditional risk factors for sleep disorders. Future research investigating the sleep-diabetes relationship is warranted in this population.
A Review on Novel Corona Virus SARS-CoV-2 and its Ocular Manifestations
Authors: SH Behera
Published: January 2023

A novel coronavirus (nCoV) pandemic named as coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) emerged from Wuhan, Hubei, China in December 2019, spread in almost all continents, countries, territories across the world and became a threat to human population. Some reports of ocular infections along with respiratory infection in the patients of COVID-19 were also reported during this pandemic. The ocular manifestation of this virus has not completely been established yet; hence more research is needed to confirm the association of SARS-CoV-2 with ocular infections. However few reports have already been published about the association of corona virus infections in various animals. Clinical symptoms such as conjunctivitis, retinitis, and anterior uveitis are documented in feline and murine models, which on diagnosis were proved due to the corona virus infections. In this review article, some evidences of the association of SARS-CoV-2 with ophthalmic infections in the current pandemic and some published reports of corona virus infections in some animals has been briefly highlighted. Simultaneously we have tried to explain briefly about some research ideas that may establish the ocular association of this virus. We have also tried to suggest some new visitor’s policies in ophthalmic settings and some preventive measures those can be obeyed by an Ophthalmologist and other associated staffs during consultation to prevent themselves and to break spread of infections. We hope that, this article will inspire some researchers and Ophthalmologists to establish the exact pathophysiology behind the SARS-CoV-2 infections in ocular system.
Participation of Vision in the Perception of Two-Dimensional Objects with a Variative Form
Authors: B Alla
Published: January 2023

The article deals with the problem of the participation of vision in the perception of objects of variable, soft form. The analysis of the mental process of perception with the help of perceptual influences on an object of variable form is carried out. For the study, experimental equipment in the form of a tablet was developed and a special program was created to record hand movements when applying perceptual influences. The subjects were students in grades 1-4. The idea is substantiated that a person with the help of a tactile and visual analyzer is able to accurately reveal the properties of softness, elasticity, and viscosity of objects. It was revealed that vision is a necessary component in their study. Based on the study of the problem, it has been established that vision "prompts" the hand to the correct trajectory for applying perceptual influence on the studied soft object. The article summarizes the theoretical provisions, supported by practical experience.

Authors: A Shrestha
Published: January 2023

Background: Diabetic retinopathy (DR) is one of the preventable causes of visual impairment and blindness in the world. In resource limiting country, treatment of diabetic retinopathy is very challenging. So, early diagnosis and appropriate preventive approach should be a mainstay of strategy. It is of utmost important issue to explore the status of awareness of diabetic patients about diabetic retinopathy in Eritrea. Objective: To study the demographic and general characteristics of diabetic patients and their awareness about diabetic retinopathy. Methods: A hospital-based cross-sectional study was carried out at Berhan Ayini Hospital (BAH) in Eritrea from January 2014 to August 2014. The study included all consecutive diabetic patients visiting the retina clinic. The study variables were demographic characteristics and awareness of diabetic patients on diabetic retinopathy. Result: The mean age of new diabetic patients visiting the clinic was 58.81 (12.97) years. For every three males attending the retina clinic, there were two females. Twenty-two % of the patients were illiterate. Awareness about diabetic eye diseases was found in 89.3% of patients. Conclusion: A high rate of awareness among patients about diabetic eye complications is encouraging. Less service utilization by female patients raises the questions of possible gender inequity in Eritrea. Diabetic retinopathy screening program should be conducted to increase attendance of diabetic patients before retinopathy develops in Eritrea.

Methods: In this prospective randomized controlled study, 30 eyes of 30 patients undergoing phacoemulsification were assigned to 2 groups. 15 eyes (Intracameral Group A) received 0.2ml of a combination of tropicamide 0.02%, phenylephrine 0.31% and lidocaine 1% just after the first incision. While 15 eyes (Group B) received a topical regimen of one drop of each of cyclopentolate hydrochloride 1% and tropicamide 1%, every 15min for 1hour preoperatively. The main outcome measures were safety on corneal endothelium, by comparing the preoperative and 3 weeks postoperative corneal endothelium cell count in the two groups. Efficacy was also evaluated by measuring pupil size before capsulorhexis and before intraocular lens implantation, in both groups. Results: There was no significant statistical difference in the percentage of endothelial cell loss between the Groups A (27.4%) and the reference Group B (25.7%), with P value (0.595). Regarding Pupillary dilatation, adequate dilatation (>7.4mm) was achieved in both groups. Dilatation was maintained to the end of operation in the Fydrane group, while in the reference group, reduction in pupillary dilatation occurred in 20% (3 cases) reaching pupil diameter 5.5mm before IOL implantation. Conclusions: This study showed that intracameral injection of tropicamide 0.02%, phenylephrine 0.31% and lidocaine 1% is safe on corneal endothelium and effective in maintaining pupillary dilatation throughout the surgery

Authors: MS Noman
Published: January 2023

Purpose: To describe the patterns of outcomes and management approaches to patients diagnosed with angle recession glaucoma presenting at the Glaucoma Department, Chittagong Eye Infirmary & Training Complex, and Bangladesh. Design: A hospital-based prospective observational case series review. Participants: 25 patients who were diagnosed with angle recession glaucoma over a 1 year period from November 1st 2009 to October 31st 2011. Method: Patient particulars, history and mechanism of trauma were recorded. Ophthalmic examination details (including gonioscopy, intraocular pressure and fundoscopy) and management given were documented. Similar relevant details were recorded for three follow-up periods, on all patients, extending over a total period of 9 months. Results: 25 patients with angle recession glaucoma were included in the study. Twenty-two of the patients were male. The mean age of patients was 34.9±20.84 years (Range: 9-72 years). All patients had an angle cleavage of more than 180 degrees, with 68% having a recession of 360 degrees. 56% had a history of hyphaema. In 88% of patients, the intra-ocular pressure (IOP) was controlled and kept at a stable level (<21mmHg) over follow-up. Of these, 91% were controlled by conservative treatment (topical anti-glaucoma drugs or observation) and 9% was controlled after cataract surgery. Patients with uncontrolled IOP (12%) were advised for filtration surgery. The mean IOP at time of diagnosis was 29.8±9.7mmHg (Range: 14-50mmHg). The mean IOP at last follow-up was 18.4±8.4mmHg (Range: 10-50mmHg). Visual Acuity (VA) for 23 patients (92%) either remained stable or improved. Conclusion: Angle recession glaucoma can cause further loss of vision in ocular trauma patients who may already have compromised vision due to injury. Control of IOP and preservation of presenting VA was seen in most cases with conservative management with topical medications and sustained follow-up. Patients sustaining blunt ocular trauma, especially those associated with hyphaema, should be advised for future follow up and have gonioscopic evaluation of the angle.

Objective: To outline the clinical presentation, management and outcome of lens induced glaucoma in Chittagong Eye Infirmary and Training Complex. Methods: A case series review was done among the patients who visited Chittagong Eye Infirmary and Training Complex from January 2015 to December 2018. Demographic data, clinical presentations, management and outcome were recorded and analysed. Results: 30 phacomorphic cases and 20 phacolytic glaucoma patients were included in our study. The mean age at presentation was 60 years. Female to male ratio was 2:1. The reason for late presentation was distance which was 60% in phacomorphic glaucoma and 50% in phacolytic glaucoma. The main symptoms were reduced vision followed by ocular pain and redness of eye. Visual acuity was either HM or just PL in all eyes before surgery. All patients underwent SICS with posterior chamber lens implantation. IOP reduced tremendously upon discharge and vision kept improving up to a month after surgery. Conclusion: Reduced vision, ocular pain and redness are the main clinical presentations of lens induced glaucoma. Cataract surgery proves to be effective in lowering IOP and visual recovery in patients with lens induced glaucoma.
COVID-19 Epidemic: View from an Ophthalmologists Eye
Authors: J Sahu
Published: January 2023

COVID-19 pandemic is one of the worst medical emergencies the world has seen in quite some time. Still surrounded by a lot of controversies, it has managed to give all clinicians a run for their lives. In present circumstances, it remains of utmost importance that the right practice guidelines are made to reach clinicians in every possible way. Ophthalmologists remain an important link with coronavirus after preliminary reports of conjunctival and tear related spread in Chinese literature. There has been a lot of speculation and confusion for ophthalmologists in such circumstances. They do not want to disregard patients and at the same time are worried about the community spread from any probable case reporting to them. In such scenarios, it becomes critical to understand the current standard operating protocols for ophthalmologists.

This study assesses the role of strategic groups in the formulation of composite budgets and the dynamics of power play at the Tamale Metropolitan Assembly. It deals with the questions of how participatory budgeting is operationalized, how strategic groups affect the composite budget system, and how strategic groups' participation in the composite budget is determined. It uses purposive sampling to select 45 members of strategic groups that are critical to the Assembly's composite budgeting processes. Data collected were mainly qualitative; key informant interviews, observations and focus group discussions. Strategic groups have varying degrees of interest in social intervention programs that do not significantly influence the Assembly's composite budget processes. The paper found that members of the executive committee, the budget committee, heads of decentralized units, and business executives generally have a high level of influence on the budget. The only opportunities for non-state actors to participate in the processes are the town hall and council sessions which are limited and technical for most non-state actors to follow. The paper recommends that it is necessary to strengthen the capacity of the non-state actors to guarantee that all interested parties participate fully and effectively in the composite budget system.

En este documento se presenta el desarrollo y ensayo de una plataforma de prototipos de control rápido (RCP) para sistemas fotovoltaicos. La plataforma propuesta tiene por objeto apoyar la evaluación tanto de los controladores de tensión de los sistemas fotovoltaicos como de los algoritmos MPPT, dedicados a los sistemas fotovoltaicos, sin necesidad de construir un banco de pruebas para cada aplicación. En cambio, la plataforma proporciona un entorno experimental unificado, fácil de utilizar, para probar las estrategias de control en condiciones realistas, antes de su aplicación final en los dispositivos comerciales. El sistema RCP propuesto es capaz de medir, en tiempo real, las variables físicas necesarias para evaluar el comportamiento de las estrategias de control, sin necesidad de construir sensores dedicados o utilizar equipos costosos. La plataforma se basa en la combinación de hardware de bajo costo (placa Arduino) y software comúnmente disponible (Matlab/Simulink), que proporciona un entorno fácil de usar para los no expertos en la programación de dispositivos incorporados. La usabilidad del sistema RCP se valida utilizando un controlador de tensión PI clásico y perturba y observa el algoritmo MPPT, pero se puede probar cualquier otra estrategia de control. Por último, los resultados muestran que la plataforma propuesta proporciona resultados similares en comparación con las simulaciones detalladas, lo que confirma la correcta implementación tanto del controlador de tensión como del algoritmo MPPT mediante la plataforma RCP

Los residuos mineros (RM) generan grandes problemas ambientales debido a la alta y progresiva explotación de minerales y su consecuente disposición. La activación alcalina es un método ampliamente utilizado para la fabricación de materiales de construcción, usando los residuos como materiales cementantes suplementarios. En esta investigación se generaron morteros a partir de RM activados alcalinamente. Se estudiaron residuos de la explotación de minería aurífera de veta, activadas mediante una mezcla de solución NaOH y Na2SiO3. Se fabricaron dos tipos de morteros, uno utilizando el residuo con granulometría original y el otro con el residuo molido, para evaluar la influencia del tamaño de partícula. Además, cada tipo de mortero fue fraguado a 24 y 80 ºC. El análisis de las fases presentes en los morteros se llevó a cabo mediante difracción de rayos X (DRX) y el análisis de la morfología de las superficies de fractura después del ensayo de compresión se llevó a cabo mediante microscopía electrónica de barrido (MEB). Los resultados mostraron que la resistencia a la compresión es superior en los morteros preparados con los residuos molidos, frente a los morteros con los residuos de granulometría original. En adición, el incremento de la temperatura de fraguado no presentó influencia en la propiedad evaluada.

La minería a pequeña y gran escala en el Bajo Cauca Antioqueño genera un aporte significativo a la producción de oro a nivel departamental, siendo motor de desarrollo e inversión social en el territorio (Camara de Comercio de Medellín, 2019). Sin embargo, la industria minera genera consigo una gran cantidad de desechos al ambiente, que son almacenados en estructuras de contención tipo presa a un alto costo y sin ningún valor agregado al proceso de minería (Beltrán-Rodríguez, Larrahondo, & Cobos, 2018). Por otro lado, los suelos degradados por la actividad minera del pequeño minero se han transformado en un problema para el desarrollo de la región, limitando la utilización de los recursos naturales que posee el territorio para potencializar las destrezas, conocimientos y habilidades de los habitantes del Bajo Cauca (Güiza, 2013). Estos daños generados a los suelos de la región se deben a los procesos de extracción rudimentarios y a la disposición de desechos no controlada posterior a la extracción minera por parte del pequeño minero.

De acuerdo a este panorama expuesto se hizo necesario crear alternativas de aprovechamiento de suelos degradados de la pequeña minería y relaves mineros de la gran minería de empresas presentes en la región en opciones productivas a través de su transformación y utilidad para la industria de la construcción.

Es por ello que, en esta investigación se presentan alternativas de aprovechamiento de suelos degradados y relaves mineros en el sector de la construcción a través de la fabricación de morteros de revoque y mezclas de concreto, representando con esto no solo una alternativa de reconversión laboral para los habitantes de la región sino también una alternativa de aprovechamiento de todo el material que queda como residuo posterior a la extracción minera, no solo de las empresas mineras en general sino también del pequeño minero, mitigando con ello el impacto ambiental generado con la minería a través de una alternativa productiva.
