hypoxic ischemic encephalopathy. There are very few studies comparing the neurodevelopmental outcomes in neonates with moderate to severe HIE who received and not received TH. Objective was assessment of neurodevelopmental outcome between TH and non-TH group till last follow-up.
Methods: Hospital Based Prospective study. All term neonates with Moderate to severe birth asphyxia with HIE who received TH and not received TH, admitted in NICU of BalChikitsalay, RNTMC, Udaipur, consenting for the study were followed up at age 3-6 month, 6-12 month, 12-18 month and 18-24 month from September 2018 to February 2021 and neurodevelopment outcome was assessed.
Results: 70 neonates with birth asphyxia HIE II / III were included in the study, 35 in TH group and 35 in non-TH group. Out of 70 babies enrolled 46 (65.7%) were having normal development and 24 (34.3%) were having development delay. Out of 46 who were having development delay 6 (17.4%) were of TH group and 18 (51.4%) were of non-TH group. Most of the babies of TH group i.e., 30 (85.7%) were neurodevelopmentally normal and 5 (14.3%) were having some neurodevelopmental abnormality. In non-TH group 15 (42.8%) were normal and 20 (57.2%) were having some neurodevelopmental abnormality.
Conclusions: Results of the study showed significantly better outcome in infant who received therapeutic hypothermia than those who did not.

Authors: Khan Rizwana R. , Flora Thanadar A. , Biswas Urmilata , Rashid Jubyda S. , Zabin Shirin G.
Published: September 2023

Background: Cervical cancer, ranking as the second most prevalent cancer and a leading cause of female cancer-related deaths in low to middle-income nations, exhibits a notable connection between tumor proliferation (Ki-67) and invasiveness (e-cadherin). Both factors contribute significantly to cervical cancer's aggressiveness. This study aims to establish the clinical-pathological link between e-cadherin and Ki-67 expression in cervical carcinoma, and assess their potential as diagnostic biomarkers.
Methods: This cross-sectional study spanned July 2017 to June 2019 at Sir Salimullah Medical College and Mitford Hospital Dhaka. It encompassed 60 adult female patients histopathologically diagnosed with cervical cancer. All patients underwent e-cadherin, Ki-67 expression assessments, and histopathological diagnosis. Ethical clearance was granted by SSMC Institutional Ethics Committee.
Results: E-cadherin expression presented as follows: strong intensity in 36.7% cases, weak and homogeneous in 35.0%, weak and heterogeneous in 8.3%, negative staining in 15.1%, and negative expression in 5.0%. Ki-67 mean levels varied significantly among different types of cervical cancer (p<0.05). Squamous cell carcinoma was predominant (80.0%), with heightened e-cadherin expression in well-differentiated cases (14 cases). Notably, cases with no e-cadherin expression exhibited Ki-67 mean of 71.0±7.9, while those with strong E-cadherin expression displayed Ki-67 mean of 56.5±8.2 (p<0.05). A significant negative correlation (r=-0.300; p=0.022) emerged between Ki-67 LI (%) and e-cadherin expression.
Conclusions: E-cadherin correlates effectively with clinicopathological features and Ki-67 expression in cervical carcinoma. This underscores its pivotal role in cervical cancer progression.

Published: September 2023

Reactive arthritis (ReA) is an inflammatory arthritis that manifests days to weeks after a gastrointestinal or genitourinary infection. It is also described as a classic triad of arthritis, urethritis, and conjunctivitis. Here we discuss the clinical presentation of ReA in a 20-year-old male who presented with typical triad of symptoms. But there was presence of hematuria which couldn't be explained by this single diagnosis. So further investigations where necessary to find the cause of his haematuria. A 20-year-old male student with history of childhood onset renal stone disease presented with complaints of dysuria for 3 days followed by bilateral conjunctival congestion along with pain around right hip joint, painful swelling around right ankle joint for 2 days. All examination were normal except for bilateral conjunctivitis and features of right ankle joint arthritis. His blood investigations showed neutrophilic leucocytosis with raised CRP levels. Chlamydia IgM Antibody was detected positive, which revealed the causative organism being Chlamydia Trachomatis. Urine routine showed 50-55 RBC’S and 2+ proteinuria. Hematuria was attributed to the CT evidence of renal stone and abnormal retroaortic coarse of his left renal vein described as posterior nutcracker syndrome.

Published: September 2023

Acute thrombotic closure of more than one coronary artery causing STEMI is an infrequent finding in coronary angiography during primary angioplasty in myocardial infarction (PAMI). We presented a case of 37 years old male with acute inferior wall myocardial infarction (IWMI) with complete heart block (CHB) with left ventricular failure (LVF). Coronary angiography showed thrombotic occlusion in right coronary artery (RCA) and circumflex arteries. Clinical condition improved only after percutaneous transluminal coronary angioplasty (PTCA) of both arteries. Given this unique presentation, the best management is not standardized. Further studies are needed to better predict outcomes and guide future management.

Published: September 2023

Neonatal mortality is a widely significant problem since diseases such as sepsis, apnea and jaundice have claimed the lives of 2.3 million neonates in 2021. As such, better tools need to be developed to reduce its rate. While traditional methods like Clinical risk index (CRIB) and Score for neonatal acute physiology (SNAP) have proven helpful in predicting neonatal mortality, there is a need for more efficient measures. One such approach is support vector machine (SVM), a supervised machine-learning algorithm that is primarily used for classification. SVM can perform both linear and non-linear classification; it conducts the latter with the assistance of the kernel trick and functions such as polynomial, gaussian, RBF and sigmoid functions. This narrative review aims to explore the potential and limitations of SVM in predicting major global causes of neonatal mortality. We searched through articles employing SVM to predict different diseases and symptoms such as sepsis, seizures, fetal heart rate, low birth weight, hypoxic-ischemic encephalopathy, apnea, jaundice and neonatal respiratory distress syndrome, and concluded that while SVM has its merits and has shown promising results in many aspects, it also has its demerits such as requiring an extensive training time to achieve higher accuracy and precision.
A prospective study of clinicopathological profile and outcome of otomycosis in patients presenting to a tertiary care center
Authors: Puthukudy Preetham A. , Feshan Musarrat , Muthu Devipriya
Published: September 2023

Background: Otomycosis is reported all over the world and it accounts for 5 to 20 percent of all cases of infective otitis externa during rainy seasons. The article's main purpose was to study the predisposing factors, most common symptoms, different species of fungi involved, and the treatment outcome of otomycosis. A Chi-square test was used to analyze the association of various factors. Statistical package for the social sciences (SPSS) version 20 was used for statistical analysis.
Methods: In this prospective observational study, 100 patients with clinical evidence of otomycosis were evaluated and data regarding age, gender, risk factors, clinical appearance, fungal culture, and treatment modality received were taken. Response to treatment at the 1st follow-up (at 1 week), 2nd follow-up (at 2 weeks), and 3rd follow-up (at 3 weeks) were statistically analyzed.  
Results: In our study we found the disease to be more common among the 51 to 60 years age group. Males were affected more than females. The most common occupation was housewife. The most common predisposing factor was ear picking and the symptom was otalgia followed by itching. The disease was predominantly unilateral. Aspergillus niger was found to be the most common organism. Clotrimazole was the effective drug for otomycosis and significant responses were seen at the end of the 3rd week of treatment.
Conclusions: Aspergillus niger was the most common organism causing otomycosis and responded well with clotrimazole ear drops.
A study on the utility of KOH mount and HPR in the diagnosis of post COVID mucormycosis
Authors: B. Anjalikrishna , Sachdeva Kavita , Saini Soumya , Kabade Mayur
Published: September 2023

Background: Mucormycosis is a deadly disease that mostly affects the immunocompromised. Steroid therapy following COVID-19 infection has led to an alarming rise in the rates of this rare infection. Key to management of this disease is early diagnosis. The most common modalities used for diagnosis are KOH mount and histopathological examination. In our study we compare the efficacy of these two diagnostic modalities.
Methods: Nasal endoscopy was done in all suspected cases of the disease. Nasal discharge, crusts were collected in a sterile manner and sent for KOH mount examination. Specimens collected following surgical debridement was sent for HPR examination. The results of both are compared.
Results: In our study, HPR was positive in 82.2% cases while KOH mount showed positive results in 43.5% cases only.
Conclusions: Histopathology helps in confirming the diagnosis of mucormycosis. It also helps to demonstrate tissue invasion and identification of species of fungus. But it is time consuming. KOH mount examination is rapid and inexpensive but the test shows high false negative values. Thus, KOH mount examination can be used as a screening tool while histopathological examination can be used as a confirmation test for post covid mucormycosis.

Published: September 2023

Follicular dendritic cell sarcoma (FDCS) is a rare mesenchymal neoplasm. It arises from not only from lymph nodes but also from extra nodal tissues, either as acquired lymphoid tissue or as part of the organized constitutive lymphoid tissue. We here report this rare entity which developed again after 7 years post tonsillectomy in a 5-year old male patient. Patient underwent radical tonsillectomy and adjuvant treatment is awaited. Differential diagnosis includes large cell lymphoma, peripheral nerve sheath tumor, extracranial meningioma, malignant melanoma, metastatic carcinoma, ectopic thymoma, malignant fibrous histiocytoma, and interstitial reticulum cell sarcoma. Currently, the management of FDCS includes the therapeutic guidelines similar to that of high-grade soft tissue sarcomas that is complete surgical resection of the lesion with possibility of adjuvant radiotherapy and/or chemotherapy. The ideal combination of management of FDCS has yet to be defined.

Thermal Effects on Prefabricated Box Culverts and Implications for Joint Performance under Elevated Temperatures
Authors: Di Xianjie , Wang Yijun , Huang Chunshui
Published: September 2023

With the rapid progression of urbanisation and the continual refinement of transportation networks, prefabricated box culverts have increasingly attracted attention as modern structural components. Their rapid construction and environmentally friendly characteristics have rendered them a favoured choice within the engineering community. However, under high-temperature conditions, such as in fires or high-temperature industrial processes, concerns remain about the temperature distribution within these culverts and the subsequent impact on joint performance. Although some studies have addressed the temperature distribution and thermal effects associated with these culverts, most have been grounded in theoretical assumptions or have only engaged in preliminary experiments. In this research, an in-depth analysis of the temperature distribution within prefabricated box culverts under high-temperature conditions and the implications for joint performance is undertaken. Advanced finite element analysis tools are utilised for simulations. The findings provide the engineering community with comprehensive and precise reference data, holding significant implications for the design, construction, and maintenance of future prefabricated box culverts.

Published: September 2023

The construction sector in Indonesia witnesses a significant number of work accidents, with construction sites being particularly prone to such incidents. It is imperative for stakeholders, especially project owners, to prioritize safety performance. The authorization of safety plans empowers project owners, granting them substantial influence over safety outcomes. This research employs Structural Equation Modeling (SEM) to investigate the relationship between project owners' safety leadership and safety performance, with valuable input obtained from contractors who directly interact with project owners. The identified variables encompass leader's maturity attributes, psychosocial factors, participatory approaches, communication practices, and competence levels. All interrelationships between the variables demonstrate high significance in shaping safety performance (with z-scores exceeding 1.96). Two distinct patterns are identified to characterize project owners' leadership styles. The first pattern relates to the personal maturity of the owner, while the second pattern focuses on the owner's ability to foster effective stakeholder relationships. To manifest maturity, project owners must make three key contributions: 1) ensuring safety costs are factored into the project value, 2) procuring contractors with well-defined safety policies, and 3) ensuring swift responses to accidents. These findings underscore the importance of project owners in enhancing construction safety practices, emphasizing their role beyond that of contractors.

Published: September 2023

In the endeavor to halt the transmission of infectious diseases, containment and isolation emerge as pivotal preventive strategies. The elucidation of disease spread dynamics, through the lens of mathematical models, is instrumental in forecasting epidemiological trajectories. This study presents an augmented Susceptible-Infected-Recovered (SIR) model, assimilating these preventive measures, to scrutinize the propagation of COVID-19 since its initial emergence. The combat against this pandemic has predominantly hinged upon non-pharmaceutical interventions (NPIs) including, but not limited to, mask utilization, physical distancing, patient isolation, contact quarantine, and hand hygiene. The focal point of our investigation lies in the examination of the influence of susceptible population containment and infected individual isolation on the evolution of the ongoing outbreak. The basic reproductive number, an indicator of contagiousness, is analyzed over the course of the outbreak, yielding promising outcomes.

Lažna božanstva in njih besede
Authors: Šprogar Matej
Published: September 2023

Znanost je religija in kot taka potrebuje svoje cerkve in vernike. Dejansko je v vsakdanji vojni za slednje z ostalimi cerkvami. V bitko za vernike pa je pritlehno vstopil še kapital, ki skriva svoj namen, pa vendar deluje najbolj grobo in brezobzirno. Glavno orodje delovanja vseh cerkva so besede, ki določajo človeka, človeško civilizacijo. Določajo, kaj in kako razmišljamo, določajo, kaj je prav in dobro že s tem, ko obstajajo - domače besede predstavljajo »normalno«, vse neubesedljivo pa je avtomatsko tuje in »nenormalno«. Če potem dodamo še napačno uporabo in zlorabo, hitro pridemo do trenutka, ko narobe postane prav… Vse to se seveda pozna tudi v virtualnem svetu, kjer besede vodijo razvoj (in vojne) med programskimi jeziki, platformami, s katerimi ukazujemo idealnemu sužnju – stroju. Monopol nad jeziki prinaša moč in dobiček, kar pa še ni konec zgodbe: sedaj so namreč stroji že prišli do stopnje, ko so pričeli tvoriti besede! Vse v imenu napredka; kaj sploh pomeni beseda »napredek«?

Published: September 2023

Današnja sodobna podjetja imajo vse večje zahteve na področju mobilne povezljivosti. Nastajajoče aplikacije in industrijska okolja zahtevajo večjo pasovno širino, predvsem pa izjemno nizko zakasnitev, več spektra in večjo zanesljivost. Z dodeljevanjem namenskega spektra za ta okolja s strani regulatorjev (Nemčija, Norveška, Združeno kraljestvo in druge napredne države) so v podjetjih nastali pogoji za uvajanje zasebnih mobilnih omrežij, ki so samostojna in razširjajo njihova obstoječa brezžična omrežja. Oblačno zasnovana omrežja podjetjem omogočajo učinkovito upravljanje in pomagajo pri sprejemanju hitrejših in boljših poslovnih odločitev. V prispevku smo naslovili motivacijo prehoda na oblačno arhitekturo in pridobljene izkušnje, ki smo jih pridobili ob razvoju in uvajanju oblačno zasnovanih rešitev na Kubernetesu. Razvoj 5G je zahteval usklajenost med ekipami, ki so razvijali omrežne elemente v različnih jezikih (Java, Golang, C) in enoten pristop do modernih DevSecOps praks (infrastruktura-kot-koda, avtomatizacija, varnostno skeniranje, Helm). Kubernetes in mikroservisi so nov koncept za telekomunikacijske aplikacije, ki se počasi selijo iz paradigme VNF (virtual network functions) proti paradigmi CNF (cloud-native network functions)[6]. V prispevku so izpostavljeni izzivi, s katerimi smo se soočali pri implementacij oblačnih omrežnih funkcij. Nanizane so tudi številne pridobljene kompetence, ki smo jih inženirji pridobili tekom trajanja projekta.

Authors: Kumar S. Pradeep , Yassin M. Mohamed , Marimuthu S. , Kalarani M.K. , Thiyageshwari S. , Meenakshi Guru
Published: September 2023

Background: A significant amount of rice production waste is rice husk. It is not humifiable and turns into a significant environmental pollutant if not properly utilized. Rice husk contains silica nanoparticles, which is a major inorganic component. High purity amorphous silica nanoparticles can thus be produced using simple thermo-chemical procedures without polluting the environment by cutting out the release of carbon dioxide during the process. Methods: A study was carried out to extract amorphous silica nanoparticles from rice husk ash using an environmentally benign chemical process. Utilising a variety of material characterization techniques viz., X-ray diffraction (XRD), fourier-transform infrared spectroscopy (FT-IR), field emission scanning electron microscope (FESEM), energy dispersive X-ray spectroscopy (EDS) and Particle size analyser (PSA), the extracted nanoparticles properties were confirmed. Result: The amorphous behaviour of the silica sample was confirmed using transmission electron microscopy-selected area electron diffraction patterns and X-ray diffraction analyses, whilst siloxane and silanol groups were primarily discovered using Fourier-transform infrared spectroscopy. Images obtained using scanning electron and transmission electron microscopy showed initial nanoparticles to be present along with secondary microparticles, possibly as a result of their agglomeration. The extracted amorphous silica has particles with an average diameter of 35 nm. This synthesized silica nanoparticles can be used in agriculture, nano-additives, microelectronics, sensors and in other fields.

Mortero aislante para tarrajeo de exteriores empleando paja de trigo y corcho como sustituto parcial del agregado fino para mejorar el confort térmico de las viviendas rurales en la provincia de Abancay
Authors:   , Labrin Shimizu Maria Daniela , Pacheco Valle María Fernanda
Published: September 2023

La falta de confort térmico está relacionada con la sensación de frío o calor percibida en el interior de las viviendas. La causa principal del problema es la autoconstrucción, donde se emplean materiales no aislantes y de baja calidad que debilitan el rendimiento térmico de la envolvente residencial. Por esta razón, durante la época de heladas, los descensos de temperatura aumentan la vulnerabilidad de regiones en la zona centro-sur del país, tales como Apurímac, Cusco, Puno, entre otros. En consecuencia, más de un millón de pobladores están expuestos a un alto índice de daños personales, emergencias y graves enfermedades. El problema se delimita en la provincia de Abancay, ya que las viviendas rurales no son capaces de minorizar el impacto de las heladas. Entonces, se propone el diseño de un mortero aislante para tarrajeo de exteriores, reemplazando el agregado fino con paja de trigo y corcho al 5%, 10% y 15%. Se demostró la mejora de las propiedades térmicas y mecánicas del mortero mediante ensayos de laboratorio y prototipos de vivienda. Las muestras de mortero aislante obtuvieron una conductividad térmica de 0.183W/mK, 0.166W/mK y 0.132W/mK, siendo menores al de un mortero convencional. Asimismo, presentaron una resistencia a la compresión a los 28 días de 92.5Kg/cm2, 60.8Kg/cm2 y 26.1Kg/cm2, superando la resistencia mínima de la norma ASTM-C270. Por último, los prototipos de vivienda aumentaron la temperatura interior hasta en 4.5°C en climas fríos. De esta manera, se otorgará un gran refuerzo térmico, empleando materiales oriundos de la zona, económicos y ecoamigables.

La presentación de este trabajo de investigación tiene por finalidad, lograr exponer las ventajas y posibles beneficios del uso de nuevas técnicas de estabilización de taludes, frente al uso de la técnica convencional: Gaviones; si bien esta técnica es funcional, tiene serias implicaciones ambientales, no es auto reparable, cambia drásticamente el panorama visual de las riberas de los ríos. La barrera de vetiver es una técnica nueva e innovadora, que se caracteriza por el uso de vegetación; tales como el vetiver o el bambú. Para este caso en específico seleccionaremos el vetiver, debido a que esta vegetación tiene menos requerimientos para el sembrado, cuenta con raíces profundas y entrelazadas, provee estabilidad al suelo, añade resistencia a la erosión y altera mínimamente los parámetros geométricos de la ribera del río; tiene alta resistencia a medios químicos, sequía, máximas avenidas, estar sumergidas y un amplio rango de temperatura (-10 a +55 °C). Este tipo de vegetación presenta cierta intolerancia a la sombra, lo cual es ideal debido a que la zona de estudio no presenta árboles, ni casas que puedan proporcionarle sombra. Puede crecer en suelos arenosos, zonas con piedras y desde 0 msnm hasta 2000 msnm y retiene el limo que arrastran los ríos por procesos de socavación en zonas no protegidas, por lo cual reduce las partículas en suspensión que arrastran los ríos

Las patologías en el concreto en diferentes tipos de estructuras es un problema muy común en el sector de la construcción, siendo las fisuraciones una de las complicaciones más frecuentes en aparecer, con el pasar de los años es necesario tomar acciones que involucran el mantenimiento y resanado completo en estas estructuras; muchas empresas constructoras ignoran dichos procedimientos con el fin de obtener más ganancias, estas al omitirse puede llevar a una pérdida importante de sus condiciones y propiedades físicas como el deterioro de este, y en consecuencia se llega a tener altos costos de mantenimiento en el presupuesto final. Con el fin de poder dar una respuesta frente a estas problemáticas se realizó un proyecto de investigación el cual consiste en el estudio y elaboración de un concreto convencional con una resistencia de 210 kg/cm2 mezclados con bacterias tipos bacillos dirigido a losas aligeradas, el cual le da un factor autorreparable mediante la segregación de calcita, cuando esté presente fisuras por distintas causas durante su vida útil. Como base para esta investigación, se identificó tres tipos de bacteria de la familia bacillas además de la que estamos empleando en nuestro trabajo de investigación, donde se analizaran las ventajas y desventajas de cada una desde el proceso de activación, cultivo hasta la participación de esta en la mezcla endurecida del concreto. Una vez ya elegida la bacteria a utilizar, se hará un análisis exhaustivo desde la adquisición de esta, hasta que materiales se utilizan para su adicción a la mezcla. Para después llegar a elaborar una mezcla de concreto convencional con una resistencia de 210 kg/cm2 incorporándose de manera conjunta diferentes concentraciones de bacterias bacillas pseudofirmus y lactato de calcio para la alimentación de esta. Finalmente se realizará una tabla comparativa sobre los ensayos de compresión que se realizaron, con el fin de definir como mejora la resistencia del concreto según su concentración.

Bu araştırmada; süt dişi restorasyonlarında kullanılan yeni nesil restoratif materyaller ile mineral trioksit agregatın (MTA) bağlanma dayanımına farklı adeziv uygulamaların etkisinin karşılaştırmalı olarak değerlendirilmesi amaçlandı. Üretici firmaların talimatları doğrultusunda hazırlanan MTA (ProRoot MTA), silindirik akrilik blokların üst yüzeyinde hazırlanan 4 mm çapında ve 2 mm derinliğinde standart boşluklara yerleştirildi. Hazırlanan 117 adet örnek, üzerine nemli pamuk peletler yerleştirilerek sertleşmeleri için 24 saat süresince %100 ve 37°C sıcaklıkta inkübasyona bırakıldı. Rastgele 3 gruba ayrılan örneklere (n=39) farklı adeziv materyaller (G-Premio Bond, Clearfil SE Bond, Prime Bond NT) üretici firmanın önerileri doğrultusunda uygulandı. Restoratif materyal uygulamaları için örnekler her bir grupta 13 adet yer alacak şekilde tekrar alt gruplara ayrıldı. Restoratif materyaller (Dyract XP, Cention N, ACTIVA Kids) MTA üzerine 3,2 mm çapında ve 3 mm yüksekliğinde silindirik kalıplar yardımıyla firma önerileri doğrultusunda uygulandı. Tüm örnekler 24 saat %100 nem altında 37°C'lik etüvde bekletildikten sonra makaslama bağlanma dayanım değerleri üniversal test cihazı kullanılarak ölçüldü. Gerçekleşen kırılma tipi mikroskop altında değerlendirildi. Elde edilen verilerin istatistiksel değerlendirilmesinde tek yönlü ve çift yönlü varyans analizi (One-way/Two-wayANOVA-PostHoc Tukey) ve ki kare testleri kullanıldı. Her bir restoratif materyalin adeziv gruplarına olan makaslama bağlanma dayanımı değerlendirildiğinde gruplar arasında istatistiksel olarak anlamlı farklılık gözlenmezken, her bir adezivin restoratif materyal gruplarına olan makaslama bağlanma dayanımı değerleri ortalamaları değerlendirildiğinde, SE Bond örneklerinde istatistiksel olarak anlamlı farklılık tespit edildi (P=0.029). Tüm gruplar arasında en yüksek ortalama makaslama bağlanma dayanım değeri adeziv olarak SE Bond kullanılan Cention N örneklerinde gözlendi. Tüm gruplarda çoğunlukla koheziv kırılma tipi tespit edildi. Cention N ve ACTIVA Kids restoratif materyallerinin MTA’ya olan bağlanma dayanımları adeziv tipine göre değişmekle birlikte klinik kullanıma uygun referans değerler göstermektedir.
Eucalyptus Planting in Pasture Matrix and Erosive Reactivation of Gullies in the Sesmaria River Basin (SP/RJ): a cycle of instability in headwater valleys

Published: September 2023

In the 21st century, eucalyptus plantations have expanded in the middle valley of the Paraíba do Sul River, in the southwestern region of Brazil, replacing degraded pastures. Some studies associate these plantations with the reduction of groundwater levels, but field observations have indicated that erosive activity related to permanent and temporary underground water flows is more significant. This study focuses on the reactivation of erosive processes leading to the regressive growth of gullies after the introduction of eucalyptus in pasture areas. Infiltration experiments, soil suction monitoring, well water levels, and gully erosion were conducted after the introduction of eucalyptus. The results indicated that eucalyptus cover facilitated rainwater infiltration, feeding temporary and suspended aquifers. These flows, combined with the permanent aquifer, caused erosion due to excessive pressure on gully margins, bottoms, and slopes. Erosion rates decreased over the years after the introduction of eucalyptus. Tree vegetation began to recover in the gullies, indicating a trend towards stabilization. In response to changes in land use, the drainage and erosion system are undergoing an internal adjustment period in search of a new balance and stability.

As ilhas do arquipélago Shetland do Sul apresentam rápidas mudanças ambientais decorrentes das condições climáticas, promovidas pelo aquecimento regional registrado nas últimas décadas. A ilha Deception, localizada no arquipélago, é a mais meridional das ilhas Shetland do Sul e contém o maior vulcão ativo da Antártica Marítima. As últimas erupções subglaciais que ocorreram entre 1969 e 1970 afetaram o balanço de massa das geleiras locais. Este estudo buscou evidências de processos ambientais na ilha Deception por meio da análise sedimentológica e medições de propriedades físicas em testemunhos sedimentares marinhos. Os resultados dos sedimentos referentes ao cone vulcânico submerso Ferraz Peak indicam a granulometria predominante em silte arenoso que se diferenciou das outras áreas que predominam em silte argiloso. O parâmetro da susceptibilidade magnética sugere valores de distinção entre a sedimentação de origem vulcânica (>150 SI x 10^-5), marinha e glacial (< 120 SI x 10^-5). Dados geoquímicos apresentaram teores maiores de Fe-Mn que sugerem mineralização hidrotermal submarina nos sedimentos do cone vulcânico Ferraz Peak. Portanto, as características sedimentares da ilha apresentam a dinâmica sedimentológica e as variabilidades ambientais da região.
Improving orientation mapping by enhancing the diffraction signal using Auto-CLAHE in precession electron diffraction data

Precession electron diffraction (PED) is a powerful technique for revealing the crystallographic orientation of samples at the nanoscale. However, the quality of orientation indexing is strongly influenced by the quality of diffraction patterns. In this study, we have developed a novel algorithm called Auto-CLAHE (automatic contrast-limited adaptive histogram equalization), which automatically enhances low-intensity diffraction pattern signals using contrast-limited adaptive histogram equalization (CLAHE). The degree of enhancement is dynamically adjusted based on the overall intensity of the diffraction pattern, with greater enhancement applied to patterns with fewer spots (i.e., away from zone axes) and little or no enhancement applied to patterns with many spots (i.e., at a zone axis). By improving the visibility of low-intensity diffraction spots, Auto-CLAHE significantly improves the template matching between experimentally acquired and simulated diffraction patterns, leading to orientation maps with dramatically higher quality and lower noise. We anticipate that Auto-CLAHE provides an efficient and practical solution for preprocessing PED data, enabling higher-quality crystal orientation mapping to be routinely obtained.
