Combustible de Aviación Sostenible (SAF), como alternativa para la reducción de gases de efecto invernadero en el sector aeronáutico en el Perú
Authors: Bravo Artica José Luis 
Published: November 2024

La industria aérea, responsable del 2,5% de las emisiones globales de CO2 y otros gases nocivos, busca reducir su impacto ambiental. El aumento en la demanda de vuelos ha llevado al Reino Unido a contemplar un aumento del 10% en los precios de los boletos para gestionar la demanda y reducir vuelos comerciales. Los biocombustibles, especialmente el Combustible de Aviación Sostenible (SAF), destacan como alternativas prometedoras al ser fabricados con recursos renovables y al utilizarse en algunos aeropuertos. Un estudio evalúa los beneficios del SAF en la reducción de emisiones de gases de efecto invernadero, comparándolos con combustibles fósiles en términos de costos y rendimiento. En 2019, en Perú, el uso de SAF demostró una reducción del 28% en emisiones. La investigación se centra en la viabilidad de los biocombustibles, especialmente el SAF, para disminuir emisiones en la industria de la aviación. La metodología implicó comparar las emisiones de combustibles fósiles con SAF al 30%, elaborado con aceite usado de cocina, logrando una reducción del 28% en las emisiones de gases de efecto invernadero. A pesar de las ventajas del SAF, se destacan desafíos como el alto costo y el rendimiento comparativo con combustibles convencionales, subrayando la necesidad de abordar aspectos económicos para una implementación efectiva.

From the Village to the Táncház: The Revival Metamorphosis of a Peasant Flute Player
Authors: Salamon Soma 
Published: November 2024

AbstractDuring an inevitable rural-to-urban conforming process, the Hungarian revival movement, known as táncházmozgalom, has left marks of change on the knowledge of tradition bearers, which is the very source and condition of its existence. The aim of preserving original cultural frames of music and dance in its new environment was obvious, and still active village musicians and dancers have been respected (or even idolized) as the protagonists of the movement from the onset. Still, their original social roles as well as the status and function of their knowledge have been misinterpreted in multiple cases. Despite deliberate attempts to maintain authenticity, the result is a brand-new milieu with new musical phenomena, differing greatly from the original forms of musical tradition. The case study presented here concerns one of the last living Hungarian peasant musicians, András Hodorog. He and his unique technique of playing the furulya (flute) are highly regarded in the movement. After nearly two decades of recording, learning, and researching Hodorog's flute technique, comparatively monitoring changes in his instrumental style and repertoire, I have discovered that certain aspects of his musical profile would not have evolved without the impact and demands of the Hungarian revival movement.
Among-population variation in sexual size dimorphism of Nepa cinerea (Heteroptera: Nepomorpha)
Authors: Bakonyi Gábor , Seres Anikó 
Published: November 2024

AbstractNepa cinerea is a common aquatic predator. It is widely distributed in various aquatic biotopes of the Palaearctic. Body size is an important trait that impacts the fitness and survival of animals and thus their evolution. Like most insects, N. cinerea males are smaller than females, but sexual size dimorphism (SSD) has not been investigated. We investigated the extent of SSD, the validity of Rensch's rule, and morphological differences between nine populations based on 51 morphological parameters. Females were found significantly and marginally significantly larger than males in all but one population. However, no difference in body length was found between the populations. Population had a significant effect on 12 traits for females and only on 5 for males, showing that females are more variable than males. Specifically, differences were found in the length of the second and third leg pairs. We did not find any support for the Rensch's rule. Nevertheless, female body size and SDI (sexual dimorphism index) were positively correlated. We suggest that fecundity selection accounts for female-biased SSD in N. cinerea.

AbstractIt is well known that prolonged rainwater erosion can adversely affect the surface texture of asphalt pavements, leading to a rapid decline in their skid resistance. This study utilized a small-scale accelerated loading device, a high-precision 3D scanner, and digital image processing technology to investigate the surface texture wear process and skid resistance decay trends of basalt asphalt pavement and steel slag asphalt pavement under water erosion and traffic load. The results indicate that under submerged conditions, the skid resistance (BPN) of asphalt pavement declines rapidly during the first 500,000 load cycles, and the rate of decline gradually stabilizes after 500,000 cycles. After 1.2 million load cycles, the BPN of basalt pavement decreased by 28.10%, while that of steel slag pavement decreased by 21.18%, indicating that the skid resistance of steel slag pavement is significantly better than that of basalt pavement. Texture parameters—namely, root mean square height, peak material volume, core material volume, void volume of the core, and valley void volume—exhibited the same decay trend as BPN. The average correlation coefficients between BPN and texture parameters were 0.846, 0.848, 0.898, and 0.916, respectively, indicating that texture parameters can be used as evaluation indicators for skid resistance decay. Finally, the decay of pavement skid resistance was predicted using an exponential decay equation.

In Industrial applications, DC motors are commonly applied because of high reliability, ease of control and ability to provide accurate speed. However, to get accurate speed control under several operation conditions such as disturbances and changes in the load is significant challenge. This research explores the implementation of particle swarm optimization (PSO) to tune parameters of proportional-integral (PI) controller. PSO that is a population-based optimization technique, is inspired by the social behavior of swarms. It is a population-based optimization technique. By automation process in the algorithm. Using the tuning process of PSO, it can effectively obtain the parameters of PI controller. experimental hardware using DIGIAC 1750 is used to assess the performance of the proposed method. The parameters of and are 0.7492 and 0.2007, respectively. The results show that the performance of the DC motor using PSO tuned by PI for , , and are 0.3687 s, 0.5106 s, and 0.6051 s, respectively. Furthermore, when the system is given a disturbance, the response can come back again following the setpoint and when the setpoint is changed, the response can follow the setpoint quickly as well. The proposed method can address the challenges associated with DC motor speed control.
Study on Depositional Elements and Sandstone Body Development Characteristics Under High-Resolution Sequence Framework of the Fuyu Oil Layer in Bayanchagan Area

Published: November 2024

Summary
With the development of oil and gas exploration, the tight oil in Daqing Oil Field has attracted attention. In recent years, the Fuyu oil layer in the northern Songliao Basin has become a focal point for exploration; however, the study of depositional elements in this area remains insufficient. Based on several analyses of sandstone thickness, depositional environment, heavy minerals, rock color, sedimentary structures, and logging curve characteristics, as well as stratigraphic division and comparison in the Bayanchagan area’s Fuyu oil layer, it has been revealed that the clastic source directions are northwest and west. The area features river-dominated, shallow water lacustrine delta deposits. These deposits are further divided into two subenvironments: delta plain and delta front, encompassing eight depositional elements. The main depositional elements are distributary channels, crevasse splays, floodplains and overbank sand lenses, subaqueous distributary channels, river mouthbars, interdistributary bays, and frontal splays. The whole oil layer in the study area is in the background of a transgressive deposition, during which lake level oscillates and several water regressions occur, thus establishing the sedimentary evolution characteristics of the oil layer in the study area. The Fuyu I (FI) sandstone thickness and oil layer thickness in the study area are the largest, with the widest distribution range, while the Fuyu III (FIII) is the least developed; the Distributary channels are the most effective oil and gas depositional elements. Vertically, the FI and Fuyu II (FII) oil layers are the most developed, and gradually deteriorate downwards.

Abstract

Er3+ and Yb3+ doped CaTiO3 phosphors were prepared using combustion synthesis. The synthesized samples underwent comprehensive analysis to evaluate their structural, morphological, and optical properties. This analysis encompassed techniques such as X-ray powder diffraction, field emission scanning electron microscopy, and photoluminescence investigations. A meticulous luminescence investigation was conducted on the synthesized samples. The study revealed that erbium ions (Er3+) exhibited distinct green and red emissions when subjected to excitation by a 980 nm infrared (IR) source. These emissions were attributed to the 2H11/2, 4S3/2 → 4I15/2 and 4F9/2 → 4I15/2 electronic transitions, respectively. The up-conversion process of the synthesized phosphor, CaTiO3:Yb3+, Er3+, was examined through the analysis of power-dependent emission spectra. Subsequently, a rate equation model was proposed to elucidate this process. To evaluate the thermosensitive capabilities of the phosphor, the temperature-dependent responses of different thermally and non-thermally linked emission lines associated with Er3+ were investigated. Temperature sensing measurements were performed between 303 and 583 K using the fluorescence intensity ratio technique. Relative sensitivities of 1.14, 1.66, 0.15, and 0.33% K− 1 were observed across different thermally and non-thermally linked transitions. By utilizing heat and IR excitation as inputs, the versatility of the synthesized phosphor in designing logic gates was demonstrated. This scheme enabled us to attain a notable switching ratio of approximately 170.86% for the AND gate and about 72.28% for the INHIBIT gate. The synthesized phosphor exhibits considerable potential as a versatile material suitable for applications in both future molecular logic devices and optical thermometry.

Abstract

Introduction: Colorectal cancer (CRC) poses a significant global health challenge with increasing incidence and mortality rates worldwide. To address this burden, novel biomarkers are being explored to enhance early detection and improve patient outcomes. Nicotinamide N-Methyltransferase (NNMT) has emerged as a potential biomarker for CRC, showing elevated levels in CRC patients compared to healthy individuals.
Aim of the study: This study was conducted to evaluate Serum N-Methyl-Transferase as a Biomarker for Colorectal Cancer Diagnosis.
Patients and methods: In this study, we evaluated the diagnostic efficacy of NNMT in CRC by conducting a case-control study involving 160 subjects, including CRC patients and healthy controls.
Results: Our findings indicate that NNMT achieved high diagnostic accuracy in CRC diagnosis, with an area under the curve (AUC) of 0.838 at a cutoff point of 1726 pg/ml with a sensitivity of 71.25%, specificity of 85.00%, positive predictive value (PPV) of 34.5%, and negative predictive value (NPV) of 96.4%. The high NPV of NNMT makes it a valuable asset in ruling out CRC, potentially reducing unnecessary procedures and improving patient care.
In conclusion, our study provides compelling evidence supporting NNMT as a promising biomarker for CRC diagnosis. Integrating NNMT into routine clinical practice has the potential to enhance early detection, risk stratification, and ultimately improve patient outcomes in CRC. Further research and validation studies are warranted to establish the clinical utility of NNMT and its role in CRC management.

Abstract

This study reports the first pig-to-human lung xenotransplantation using a six gene-edited pig lung. A left lung from a gene-edited Chinese Bama Xiang pig was transplanted into a 39-year-old brain-dead human recipient. The xenograft maintained viability and functionality for 216 hours without signs of hyperacute rejection. Postoperatively, severe edema resembling primary graft dysfunction (PGD) was observed, potentially due to ischemia-reperfusion injury. Antibody-mediated rejection appeared to contribute to xenograft damage on postoperative days 3 and 6, with partial recovery by day 9 under the current immunosuppressive regimen. This pioneering study suggests that genetically modified pig lungs could potentially be used for future clinical applications in xenotransplantation.
Midgut Volvulus Secondary to Intestinal Malrotation and Meckel’s Diverticulitis: A Case Report
Authors: Bhattarai Bhawesh , Luitel Prajjwol , Poudel Sujan , Pariyar Suraj , Dahal Aakriti , Koirala Dinesh 
Published: November 2024

Abstract

Background:
Volvulus, a condition where the intestines twist upon themselves, is a serious surgical emergency that commonly affects children. Midgut volvulus is frequently caused by congenital malrotation, a developmental anomaly where the intestines fail to rotate and fixate properly during fetal development. Although Meckel's diverticulum, the most prevalent gastrointestinal congenital anomaly, occurs in approximately 2% of the population, its coexistence with intestinal malrotation is rare.
Case Presentation:
A 7-year-old boy presented with recurrent abdominal pain and bilious vomiting over the past month, worsening in recent weeks. Physical examination revealed mild abdominal distension and tenderness, with stable vitals. Laboratory findings indicated mild leukocytosis and elevated C-reactive protein, suggesting inflammation. Imaging studies, including X-ray, ultrasound, and contrast-enhanced CT, revealed features of small bowel obstruction, midgut volvulus, and intestinal malrotation. An emergency exploratory laparotomy confirmed a volvulus caused by a fibrous band of the vitelline duct, with Meckel's diverticulum and an inflamed appendix. The patient underwent wedge excision of the Meckel’s diverticulum and appendectomy, with an uneventful recovery. He was discharged on postoperative day 4 and remained symptom-free at a 6-month follow-up.
Discussion and Conclusion:
Midgut volvulus, primarily caused by intestinal malrotation, is a life-threatening condition in children that can lead to bowel obstruction and ischemia. While malrotation accounts for 70-80% of volvulus cases, rarer causes, such as Meckel's diverticulum, contribute to fewer than 5%. In this case, the volvulus was further complicated by a fibrous band associated with Meckel’s diverticulitis and concurrent appendicitis. Surgical intervention, including Ladd’s procedure, wedge excision of the Meckel’s diverticulum, and appendectomy, was crucial in preventing further complications. Early diagnosis and prompt surgical correction are essential to avoid volvulus-related morbidity. This case highlights the importance of recognizing coexisting conditions like Meckel’s diverticulitis and appendicitis, which can exacerbate volvulus. The patient recovered uneventfully and remained symptom-free at follow-up, emphasizing the necessity of timely surgical intervention for successful outcomes.

Abstract

Sitobion miscanthi is the dominant species and can damage seriously agricultural production. The effective management of wheat aphids was depended on chemical insecticides. However, their wide application has led to severe resistance of wheat aphids to some insecticides, and cytochrome P450 as a detoxifying enzyme plays a crucial role in the insecticide resistance. In this study, CYP6CY1, a new P450 gene was isolated and overexpressed in the resistant strain to imidacloprid. The increased sensitivity to imidacloprid after silencing of CYP6CY1 indicated that it could be participated in imidacloprid resistance. Subsequently, CYP6CY1 within the 3′ UTR targeted by miR-3047-3p was confirmed at the posttranscriptional regulatory level, and involved in the resistance to imidacloprid. These results provide opportunities for understanding the roles of P450 in insecticide resistance of pests.

Abstract

Objective: To investigate the clinical efficacy and patient-reported discomfort associated with traditional versus reverse placement of double-J ureteral stents (DJUS) in patients undergoing ureteroscopic stone removal.
Materials and Methods: This prospective, randomized, single-center, one blinded, controlled study. Participants were randomly assigned to either the control group (conventional placement) or the study group (reverse placement). Patients in the study group were further subdivided based on the orientation of the upper and lower tips of the stent (B1: upper medial/lower lateral, B2: both medial, B3: both lateral). Patient discomfort was assessed using the Turkish version of the Ureteral Stent Symptom Questionnaire (T-USSQ), and secondary outcomes included postprocedural hydronephrosis, hematuria, and urinary tract infection.
Results: A total of 120 patients completed the study. The reverse placement group (Group B) reported significantly lower USSQ (p<0.05) and reduced analgesic use compared to the control group. Midline crossing of the stent was significantly less frequent in the study group (11.7% vs. 30%; p=0.013). Subgroup analysis revealed that the B1 and B3 groups had significantly lower analgesic usage and symptom scores compared to the control group, while the B2 group reported higher hydronephrosis and symptom scores.
Conclusion: Reverse placement of DJUS, particularly when both stent ends are laterally positioned, may reduce stent-related discomfort. There is a need for a new stent design with both ends facing laterally, tentatively named "ipsi-DJUS".
