Las fermentaciones frecuentemente requieren la adición de nutrientes o inóculos, así como el control de ciertos parámetros. Esto aumenta los costos operativos y dificulta su implementación, especialmente en lugares donde no hay interés en tratar residuos orgánicos. El objetivo fue realizar una fermentación sumergida sin la adición de inóculo y utilizando solo residuos de frutas y verduras para evaluar la cantidad de ácidos orgánicos y actividades enzimáticas como alternativa para obtener productos de alto valor agregado. Para ello, desechos de naranja, plátano, manzana, zanahoria, papaya y piña se utilizaron y colocaron en un recipiente de plástico de 6 L con 4 L de agua destilada y 400 g de piloncillo. La fermentación se monitoreó durante 49 días analizando una muestra de 30 mL cada 7 días. Ácidos órgánicos se cuantificaron por cromatografía de líquidos, mientras que azúcares reductores y totales, proteínas y actividades enzimáticas se determinaron por espectrofotometría. La concentración de ácido láctico (16.53 g/L) fue similar a la obtenida con microorganismos especializados. La mayor actividad de pectinasa (55 U/L) se registró al día 28. Los resultados demuestran que se pueden obtener productos de alto potencial biológico mediante fermentaciones sumergidas.

Authors: Gencer Gülcan
Published: September 2024

Bladder cancer is among the ten most common types of cancer worldwide, with approximately 550,000 new cases occurring each year. It accounts for comprehensively compared to 3% of all newly diagnosed cancer cases and contributes to 2.1% of cancer-related deaths globally. This article introduces goodness-of-fit tests that aim to fit the exponentialized exponential distribution. These tests are based on the Kullback-Leibler difference and have been applied to censored and complete samples of Bladder Cancer Patients. We calculated critical values and statistical power measurements, considering the best and worst bandwidth scenarios. We then comprehensively compared essential values and power across various parameters, accounting for optimal and suboptimal bandwidth choices derived from the Kullback–Leibler difference. In the final phase of our study, we used a dataset of individuals diagnosed with bladder cancer to demonstrate the practical applicability of our proposed research. Finally, this modeling type can benefit researchers and healthcare professionals through time-to-event analysis (survival analysis), investigation of events, medical decision-making, and risk prediction.

Trifolium pratense L. flowers (TPF) were collected and dried in shade in this study. After extraction in methanol, a diluted solution was applied to the liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) device to determine the bioactive compounds quantitatively. Isoquercitrin (38.64 mg/g extract), coumarin (13.66 mg/g extract), and catechin (12.52 mg/g extract) were verified as major products. Antioxidant activity of TPF was performed using a potentiometric PVC membrane sensor to evaluate 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and total phenolic content of TPF. TPF inhibited the DPPH radical as 31.4 ± 0.02% at the 500-ppm concentration. However, the DPPH activity of gallic acid was determined as 81.43 ± 0.07% and 92.44 ± 0.1% at the TPF concentrations of 12.5 ppm and 25 ppm, respectively. In addition, the total phenolic content was calculated to be 82.4 ± 0.15 mg gallic acid eq/g extract. It was observed that TPF has the potential to be an antioxidant and a valuable source of isoquercitrin, coumarin, and catechin.

Intranasal Fentanyl Versus Morphine in Fracture Reduction in a Pediatric Trauma Center
Authors: Bisso Raoul , Tielli Alexandra , Lopes Anne-Aurelie
Published: September 2024

Purpose:

Pain management in orthopaedic manipulation in the emergency department (ED) is crucial to decrease fracture reduction performed in the operating room. This study compared intranasal fentanyl (INF) with oral morphine in time of care and effectiveness on pain during the reduction of bone fractures in a pediatric trauma center.

Methods:

A before-and-after INF implementation study was conducted in a pediatric ED with a trauma center on children with a confirmed displaced closed fracture on radiographs with reduction and casting performed in the ED. The time of care, time for sufficient analgesia, effectiveness on pain, and tolerance were compared between both analgesics in 3 consecutive phases.

Results:

77 children were included: 31 children received oral morphine and 46 INF. The time of care was shorter in the INF group (150 [111 to 193] minutes versus 215 [155 to 240], P = 0.01) as the time for sufficient analgesia (10 [9 to 13] minutes versus 80 [53 to 119], P < 0.001) with a higher pain reduction after a dose of INF (3 [0 to 4] versus 6 [3 to 7], P < 0.001) and less dose requirement (P = 0.002). Although pain scores were similar at arrival in both groups (P = 0.15), the pain was significantly lower before and during the procedure in the INF group and equivalent after the procedure (2 [0 to 4] versus 3 [0 to 5], P = 0.02, 3 [1 to 5] versus 7 [3 to 9], P < 0.001, and 1 [0 to 2] in both groups, P = 0.87, respectively). Keeping pain levels low during the procedure in the INF group allowed the extension to lower limb fracture reductions (P = 0.04). No serious adverse events were reported.

Conclusion:

INF reduces the time to obtain sufficient analgesia and time of care, with good effectiveness maintained during the procedure in fracture reduction, allowing the extension to lower limb fractures. Thus, this rapid and efficient analgesia facilitates orthopaedic care in the pediatric ED that would otherwise require to be reduced in the operating room under general anesthesia.

Authors: Dartono Dartono , Santoso Budi
Published: September 2024

Ancaman eksistensi negara kian kompleks, namun kesadaran bela negara kaum muda cenderung reaktif dan stag pada orientasi ancaman fisik. Peran keluarga, sekolah, dan masyarakat sebagai pilar pendidikan terindikasi berjalan sendiri-sendiri. Studi literatur ini bertujuan menjelaskan tentang kesadaran, pengaruh faktor dominan, serta alternatif strategi pembangunan bela negara bagi generasi muda di era globalisasi. Melalui penerapan metode deskriptif-kualitatif studi menyimpulkan; (1) Ancaman eksistensi negara yang kian kompleks belum direspon pemahaman generasi muda secara komprehensif. Konsekuensinya kesadaran bela negara mereka pun belum kontekstual, (2) Kehadiran ancaman non fisik yang juga destruktif seperti faham kontra nilai Pancasila dan kearifan lokal, membanjirnya produk import, dll. terasa begitu natural, sehingga kebanyakan generasi muda tidak menyadarinya, (3) Kontekstualisasi pemahaman melalui pendidikan menjadi elemen terpenting, dan materi faham kontra nilai-nilai Pancasila dan kearifan lokal, ancaman produk import, dll. sebagai ancaman atas eksistensi negara menjadi prioritas insersi dalam pendidikan, baik di lingkup keluarga, lingkup sekolah, maupun lingkup masyarakat. Keberadaan langkah dan kebijakan yang relevan juga sangat diperlukan guna terus meningkatkan efektivitas pelaksanaannya.

Semakin majunya teknologi dewasa ini mendorong teknologi perang hingga generasi ke-6. Perang generasi ke-6 adalah perang yang melibatkan teknologi kecerdasan buatan, satelit, dan robotik. Juga mengisyaratkan bahwa perang telah melampaui cara-cara konvensional, tak lagi harus saling berhadapan atau face-to-face. Perang generasi ke-6 juga melibatkan kendali C4ISR, yaitu Command, Control, Communication, Computer, Intelligence, Surveillance, dan Reconnaissance. Hal ini berujung kepada peningkatan penggunaan gadget pendukung seperti laptop atau komputer. Penggunaan gadget dalam waktu yang lama menimbulkan dampak buruk bagi kesehatan khususnya bagian mata. Penulis menganalisis sistem program yang berfungsi sebagai pengukur jarak antara wajah dan mata dengan layar monitor berbasis bahasa pemrograman python menggunakan algoritma Haar-cascade Classifier. Program bekerja dengan mengakses kamera bawaan atau yang terintegrasi dengan gadget sebagai sensor. Apabila jarak mata dan wajah dengan layar monitor terlalu dekat, program memberikan pesan peringatan disertai suara buzzer. Hasil pengujian program dapat mendeteksi jarak antara mata dan wajah dengan layar monitor hampir sama seperti jarak aslinya. Program dapat mendeteksi mata dan wajah lebih dari satu subjek dalam satu frame dan dapat bekerja dalam kondisi cahaya ruangan yang minim. Sistem ini harapannya dapat diaplikasikan pada lab komputer yang ada di satuan pendidikan dan satuan operasi untuk menjaga kesehatan mata para personel karena personel merupakan sumber daya yang penting guna mempersiapkan perang generasi ke-6.

Coelhos possuem os olhos mais proeminentes para aumentar seu campo de visão e proteger de predadores, todavia isso aumenta o risco de traumas, sendo relativamente comum lesão ulcerativa córnea. A ruptura da barreira epitelial e exposição de estroma gera edema e opacificação da estrutura córnea, além de possíveis sinais clínicos decorrentes do desconforto ocular como blefaroespasmo e lacrimejamento excessivo. O presente trabalho visou relatar o tratamento de uma ceratite ulcerativa em coelho doméstico (Oryctolagus cuniculus domesticus) da raça Mini Lop. Tutor relatou desconforto ocular e opacidade em olho esquerdo, no exame clínico a olho nu, além da opacidade foram observados blefaroespasmo e opacidade de córnea em olho esquerdo, e discreta hiperemia conjuntival em ambos os olhos. Foi realizado teste de fluoresceína com o auxílio da lâmpada de fenda em azul de cobalto sendo evidenciada ceratite ulcerativa superficial em ambos os olhos, com maior extensão no olho esquerdo. O tratamento clínico consistiu na utilização de medicações tópicas, com Tobramicina 0,3%, diclofenaco sódico 0,1% e lubrificante a base de hialuronato de sódio a 0,15%. O protocolo terapêutico se mostrou eficaz obtendo resolução completa em aproximadamente duas semanas.

O Traumatismo Cranioencefálico (TCE) é um problema grave de saúde pública no Brasil, com alta incidência na população economicamente ativa. Este estudo analisa casos de TCE no Rio Grande do Norte, de 2018 a 2024, para compreender prevalência, causas e impactos. Dados do Sistema Único de Saúde (DATASUS) indicam que o TCE predomina entre homens de 20 a 29 anos. O ano de 2020 registrou o maior número de casos, com uma predominância em atendimentos de urgência. As causas mais comuns são acidentes de trânsito, quedas e agressões, com os homens mais vulneráveis devido a fatores comportamentais e socioculturais. O TCE resulta em altas taxas de mortalidade e sequelas neurológicas. O estudo enfatiza a importância de políticas públicas preventivas para mitigar os impactos do TCE, melhorando a qualidade de vida dos afetados e destacando a necessidade de estratégias educativas contínuas.

Technology self-efficacy plays a pivotal role in learners’ technology uptake during their learning process in technology-mediated learning environments. This study aims to explore EFL learners’ perceived technology self-efficacy in online language learning. The quantitative data obtained in this study was via a survey questionnaire with 910 learners of a Vietnamese university. The study results revealed that the overall level of EFL learners’ technology self-efficacy was moderate, except for their high efficacy in using the Internet to gather information. Moreover, these results indicated that male learners were more confident in fulfilling online learning tasks than their female counterparts. The learners majoring in engineering showed more confidence in their capability to use computers and learning management systems in their English learning process compared to those of other majors. However, the learners’ length of time learning English had no significant impact on their perceptions of technology self-efficacy. The findings provide some insights into how the EFL learners perceive their self-efficacious beliefs of technology use in online language learning, which will help train strategies to promote technology uptake in Vietnamese higher education settings.
Temporal Variation Analysis in Clean Ice Glacier of Annapurna Basin
Authors: Subedi Sushmita , Pandit Roman
Published: September 2024

Glaciers of the Himalayas are the storehouse of fresh water. The impacts of climate change, mainly the melting of snow cover have been noticed in Nepal’s Himalayas. These changes have local as well as regional implications on water resources, and at global level on the sea level rise. This study is carried out to analyze the temporal variation of glacier retreat in the Annapurna valley from 2000 to 2020 using remote sensing technology. It is a multi-step process and involves the computation of several mathematical indices for glaciers based on the spectral properties of Landsat imagery. The final outcome is the delineation of Clean Ice Glacier (CIG) area of Annapurna basin for the years 2000, 2010 and 2020. The findings from this study reveal that the glaciers of Annapurna basin are shrinking more rapidly in the recent years than before. The decrease in CIG area coupled with the increase in the CIG number clearly indicate that the glaciers are being fragmented into smaller parts creating several disconnected ice bodies. Monitoring the dynamics of glaciers along with their trend analysis is crucial for strengthening the climate change mitigation and adaptation strategies.

Published: September 2024

A new cascaded multilevel inverter (MLI) is presented. This MLI aims to use a lesser number of switches, achieve better modularity, and reduce voltage stress. The new structure can operate in symmetric and asymmetric modes, producing all odd and even voltage levels. It comprises semi-half-bridge cells connected in series with crisscross switches to generate target voltage levels for synthesizing the sinusoidal output waveform. An extended version of the proposed MLI topology cascades sub-inverters to generate more voltage levels with reduced standing voltage. Compared to the cascading H-bridge topology, the proposed MLI and its extended version use fewer semiconductor switches. The MATLAB R2013b-based simulation results, confirm the efficacy of the proposed MLI topology.
