Authors: Moreno José Antonio Hernández , Vargas Bianca Gilliana Alcaraz
Published: September 2024

Actualmente, la tecnología del escaneo láser terrestre (TLS) representa una oportunidad de investigación con alta prioridad, ya que posee un enorme potencial como herramienta de detección remota, debido a su eficiencia para adquirir datos tridimensionales de la estructura forestal, con aplicaciones en medición, generación de ecuaciones de volumen y biomasa, modelos de competencia, entre otros. El objetivo de este trabajo fue medir parámetros dendrométricos, a partir de datos adquiridos con el TLS, y validarlos utilizando el método convencional de medición en campo, para desarrollar una metodología alternativa que combine TLS con software de uso libre. El estudio se realizó en dos parcelas mixtas de coníferas (Abies religiosa (Kunth) Schltdl. & Cham y Pinus pseudostrobus Lindl), en la Reserva de la Biosfera Mariposa Monarca, Michoacán, México. Las comparaciones entre mediciones en campo y TLS no mostraron diferencia estadística significativa (p>0.05), con un RMSE=1.34 cm y R2=0.99, para el diámetro a la altura del pecho (DAP) y un RMSE= 2.06 m y R2=0.97, para la altura total (AT). Los resultados demuestran que el TLS es una técnica eficiente para la elaboración de modelos tridimensionales de la estructura forestal in situ, que proporciona atributos precisos de los árboles. La medición de parámetros dendrométricos con TLS es confiable y aplicable en el manejo forestal. Este estudio demostró que el TLS representa un método no destructivo capaz de generar mediciones confiables y puede ayudar a generar nuevos conocimientos en el campo de la ecología forestal, debido a sus múltiples aplicaciones.

Authors: Machate David Johane , Cortes Mario Rodrigues , Oliveira Lincoln Carlos Silva de , Yoshida Nídia Cristiane
Published: September 2024

Baru nut (Dipteryx alata Vogel) oil obtained by cold pressed machine yielded 24% (mg g–1), primarily composed of unsaturated fatty acids (⁓ 79%), with oleic and linoleic acids in the proportion of 2:1. The oxidative stability assessed by Rancimat method, Thermogravimetry analysis and Differential Scanning Calorimetry revealed thermal stability, which attributed to a higher amount of oleic than linoleic fatty acids, synergistic action of the natural antioxidants and low iodine index. The nutritional qualities were calculated to atherogenic (AI = 0.07), thrombogenic (TI = 0.22) and hypocholesterolemic/ hypercholesterolemic (HH = 13.77), and physicochemical indices: acidity (0.62), peroxide (9.99), saponification (179.93) were higher, whereas iodine (93.00) and relative density (0.9121) were found between the recommended Codex Alimentarius parameters. Mineral elements were quantified using ICP OES (inductively coupled plasma optical emission spectroscopy) in decreased order of Mg > Se > Zn > Mn > Al > Cu, whereas As, Co, Cd, Cr, Fe, Ni, and Pb < LOD. In addition, this oil showed optimal indices to non-cancer risk (CR < 10–6), and non-carcinogenic: hazard quotient (HQ), and total hazard indices (HI) < 1. Nevertheless, major attention is necessary for children and Se hypersensitive consumers, which baru oil daily consumption quantity was estimated based on selenium (Se) trace element at 0.7964 g kg–1. Thus, we recommend the consumption of baru nut oil for human health promotion and metabolic disease prevention.

Authors: Rosmayanti Lina , Abimanyu Yudha , Sonhaji Imam , Faridan Juniawan Ahmad
Published: September 2024

The research aims to calculate the runway occupancy time (ROT) at Soekarno-Hatta International Airport. ROTs are crucial in calculating the runway capacity, which can influence the time it takes for the aircraft to exit the runways after landing or enter a runway before takeoff. This may have an impact on the quantity of aircraft that utilize the runway for takeoffs and landings within an hour. The Runway Occupancy Time calculation model, which is the Doratask model in the Runway Capacity Calculation Manual, is employed in this study along with quantitative methodologies and questionnaires. The data collection techniques used are observations, documentation studies and interviews. The results of this study showed that the average ROT at Soekarno-Hatta International Airport was 95.36 seconds for ROTT and 54.63 seconds for the ROTL.
Host and Environmental Factors Modulating Innate Immune Responses
Authors: Kilic Gizem
Published: September 2024

The immune system is a complex network influenced by various internal and external factors, which also affect trained immunity—the ability of the innate immune system to develop a memory response. For example, BCG vaccination, known for its protection against tuberculosis, is a well-studied inducer of trained immunity. This thesis investigates how host-related and environmental variables affect immune responses, focusing on innate immunity. The research revealed that the gene RORA, seasonal changes, and alendronate, which is commonly prescribed for osteoporosis, significantly impact the trained immunity response after BCG vaccination. Specifically, BCG vaccination in the spring, the use of alendronate on the day of BCG administration, and certain variants of the RORA gene weaken this trained immunity. Additionally, another study in the thesis found that a similar immune signature seen in severe COVID-19 patients is already present in healthy elderly individuals and males, making these groups more susceptible to severe infection. Moreover, mild to moderate COVID-19 infection does not impact immune system functionality after recovery. The findings of this thesis highlight the importance of timing vaccinations and improving vaccine formulations by considering both internal and external factors.

Bullous pemphigoid (BP) is a dermatological autoimmune disease characterized by itch and blisters. Sometimes the blisters are preceded by years of itching and eczematous patches, which can cause a delay in recognition of BP. The disease is caused by production of autoantibodies against the hemidesmosomal proteins BP180 and BP230 at the dermal-epidermal junction. An association between BP and neurodegenerative disorders, such as Parkinson’s disease, is known. However, this association is not commonly known amongst health care professionals, but is of clinical significance. Neurodegenerative disorders (including Parkinson’s disease) are thought to disrupt the blood brain barrier, resulting in exposure of neuronally located BP180 and BP230 to the immune system. In most studies that have examined the association between BP and Parkinson’s disease (and other neurodegenerative disease), BP develops several years after the diagnosis of Parkinson’s. We present a case of a patient with proven bullous pemphigoid who developed clinical features of Parkinson’s disease during follow-up at the dermatology outpatient clinic. After neurological analysis, the patient most likely suffered from long-standing Parkinson’s disease.

Published: September 2024

Construction and public works sites generate a significant amount of waste that is often costly to dispose of. To reduce the environmental impact and promote sustainability, recycling and recovering this waste is increasingly being recognized as a viable solution. This paper presents the findings of an experimental program investigating the feasibility of using brick and road demolition waste as concrete components. By substituting a portion of sand and cement with recycled materials, this study compares the properties of the reference concrete with concrete containing varying amounts of brick waste and road demolition debris. The obtained results demonstrate that the produced concrete with up to 40 % recycled content achieved a compressive strength exceeding 20 MPa after 28 days. This study suggests that recycled brick and road demolition waste could be a sustainable and economical substitute for conventional aggregates. Incorporating these materials into concrete reduces the cement content while maintaining or even improving the fresh and hardened properties of the concrete. However, it is crucial to limit the use of road demolition sand to 10 %, crushed brick fines to 20%, and brick sand (CBS) to 30% to ensure optimal performance.
Optimized Dehydrogenation of Magnesium Hydride with Fe and Cu Additives
Authors: Gbenebor Oluwashina , Popoola Abimbola Patricia
Published: September 2024

Solid state hydrogen storage with the use of MgH2 has gained widespread attention because of its good reversible storage capacity. This metal hydride however slowly releases hydrogen at high temperatures ranging between 325 – 375 oC. An important feature required of MgH2 is its ability to commence hydrogen release at a fast rate and reduced temperature. Transition metal-containing alloys/compounds having either Fe or Cu as the principal element have been used to improve the dissociation of hydrogen from MgH2.  Studies involving the use of each metal in its elemental form as an additive are minimal. This study investigated the catalytic effects of elemental Fe and Cu on the hydrogen release performance of MgH2 for potential applications in transportation and power generation. It was observed that MgH2/Fe had a better dehydrogenation performance; the temperature of onset of MgH2/Fe and MgH2/Cu dehydrogenation were 205, and 215 oC which were 98 and 88 oC lower than that for as-received MgH2.  The highest amount, 1.9 wt. % H2 was released by MgH2/Fe while 1.44 wt. % H2 was released by MgH2/Cu. The activation energy for dehydrogenation was reduced from 150.5 kJ/mol for as-received MgH2 to 89.8 and 79.8 kJ/mol in MgH2/Cu and MgH2/Fe respectively. It took 18.8 min for as-received MgH2 to commence dehydrogenation while that for MgH2/Fe and MgH2/Cu composites started from 12.2 and 13.4 min respectively. The in-situ formed Fe and Cu in MgH2 after milling acted as active catalytic sites for its improved dehydrogenation with MgH2/Fe behaving better.
Leg Length Discrepancy in Total Hip Arthroplasty: Not All Discrepancies Are Created Equal
Authors: Burnett Robert A. , Wang Jennifer C. , Gililland Jeremy M. , Anderson Lucas A.
Published: September 2024

The original review article, published in 2006, describing leg length discrepancy after total hip arthroplasty commented that “equal leg length should not be guaranteed.” There has been considerable advancement in surgical technique and technology over the past decade, allowing surgeons to “hit the target” much more consistently. In this interval paper, we review leg length discrepancy and introduce some technologies designed to mitigate this complication. In addition, we present challenging clinical scenarios in which perceived leg length may differ from true leg length and how these can be addressed with proper workup and surgical execution.

Published: September 2024

BACKGROUND: To assess Stanniocalcin-2 (STC-2) expression in breast cancer and explore its correlation with clinicopathological parameters and prognostic factors.
METHODS: In this study, immunohistochemical STC2 staining was performed on 38 breast carcinoma patients who underwent modified radical mastectomy between March 2017 and November 2022. We examined its association with various prognostic factors, including age, histopathological subtype, histological grade, T stage, nodal metastasis, distant metastasis, lymphovascular invasion, tumor-infiltrating lymphocytes, hormonal status, HER2 status, Ki67 expression.
RESULTS: The mean age was 63.4 ± 14.9 (min. 43–max. 98). High STC2 expression was found in 22 (57.9%) patients, while low STC2 expression was found in 16 (42.1%) patients. Age, histopathological subtype, histological grade, T stage, nodal metastasis, distant metastasis, lymphovascular invasion, tumor-infiltrating lymphocytes, hormonal status, HER2 status, and Ki67 expression were similar in the high and low STC2 expression groups. Overall survival (OS) was significantly higher in those with high STC2 expression (p < 0.05). However, STC2 expression did not correlate with progression-free survival (PFS) (p > 0.05). In univariate and multivariate Cox regression analysis for overall OS, STC2 expression, nodal metastasis, tumor-infiltrating lymphocytes (TIL), histological type, and PFS were identified as independent risk factors for poor OS. In univariate and multivariate Cox regression analysis for PFS, T stage, nodal metastasis, distant metastasis, TIL, histological type, and PFS were independent risk factors for poor PFS.CONCULUSION: STC2 expression positively correlated with overall survival in breast carcinomas, suggesting that STC2 can be considered a favorable prognostic factor in this context.

Published: September 2024

Objective: This study aims to determine the value of 24-hour Rhythm Holter monitoring (HM) in diagnosing and treating pediatric patients. Somebody reviewed our clinic's indications and results of 24-hour rhythm Holter monitoring.
Materials and Methods: The files of 1670 patients who applied to our clinic between January 1, 2015, and December 31, 2022, were scanned retrospectively. Somebody retrospectively evaluated and recorded age, gender, reason for admission, presence of cardiac disease, presence of cardiac disease in the family, treatment histories, family consanguineous marriages, Electrocardiography (ECG) findings, Echocardiography (ECHO) findings, and HM findings were from the hospital computer archive files.
Result: Found to be expected in 1,005 (60.2%) of the patients who underwent Holter monitoring(HM). Detected tachyarrhythmia in 408 (24.4%) patients, bradyarrhythmia in 85 (5.1%) patients, preexcitation syndrome in 73 (4.4%) patients, right bundle branch block in 27 (1.6%) patients, atrial-derived arrhythmia in 27 (1.6%) patients, genetic-related arrhythmia in 12 (0.7%) patients, pace rhythm in 12 (0.7%) patients, and other different Holter findings in 21 (1.3%) patients.
Discussion: Since arrhythmic symptoms often occur intermittently in childhood, detecting them at presentation may not be possible. A missed ECG taken at rest provides information for a short period of cardiac rhythm and many arrhythmias, so the 24-hour Holter method(HM) is helpful for diagnosis. Our study has supported that HM is used increasingly frequently and is beneficial as an easy-to-apply, noninvasive method in diagnosing arrhythmia and in monitoring and treatment planning of cases with arrhythmia.
Optic sheath diameter and microstructural changes of the optic nerve in idiopathic intracranial hypertension
Optic nerve DTI changes in IIH
Authors: balsak serdar
Published: September 2024

Abstract
Objective: We aim to investigate whether increased perioptic cerebrospinal fluid (CSF) pressure causes changes in the optic sheath diameter and microstructure of the optic nerve in patients with idiopathic intracranial hypertension (IIH). We also aim to investigate the relationship between optic sheath diameter and the optic nerve microstructural changes.
Methods: Our retrospective study is a neuroimaging study of CSF opening pressure-confirmed IIH cases and controls, including 1.5 T magnetic resonance imaging (MRI) and diffusion tensor brain imaging. Optic sheath diameters were measured from axial T2-weighted images. The optic nerve was evaluated by range of interest (ROI) with diffusion tensor imagine (DTI) and compared with the healthy control. DTI findings were correlated with optic sheath diameters.
Results: The ADC and RD values obtained from the left optic nerve were significantly increased compared to the healthy group. The FA values obtained from the right and left optic nerves were decreased considerably compared to the healthy group. We found that perioptic CSF distance increased in cases with IIH and there was a negative correlation between CSF distance and both optic nerve AD values.
Conclusion: Patients with IIH have significant DTI changes in the optic nerve microstructure, which is related to the optical sheath diameter. It may be possible to detect optic nerve damage early with microstructural changes before permanent vision loss develops and to monitor nerve damage with DTI parameters. Early recognition of optic nerve damage due to intracranial high pressure with DTI parameters is important in preventing permanent vision loss.

Published: September 2024

Aim: Constipation is frequently seen in obese individuals. It is still not fully known whether the constipation in these individuals is related only to excess weight or due to other reasons. It is limited that the hormones secreted from the gut can play an important role in constipation. In this study, we think that hormones such as intestinal peptide YY (PYY), SS, GLP-1, GLP-2 and Oxyntomodulin, which are known to have effects on bowel movements, may have effects on constipation. In this study, it will be tried to determine how the changes in the levels of the mentioned hormones with constipation in individuals who are obese and have constipation problems.
Materials and Methods: Twenty-two obese and 22 obese and constipated individuals aged 20-64 years with VKI>30 who would sign the voluntary consent form were included in the study. Individuals with chronic diseases such as diabetes and hypertension in addition to obesity, those who received psychiatric treatment and those who used alcohol were not accepted. The demographic information of the individuals was determined by the face-to-face survey method. GLP-1, GLP-2, somatostatin, peptide yy, serotonin, oxyntomodulin levels were determined with the help of commercial ELISA kit in fasting blood samples taken from obese and obese+constipated individuals in the morning.
Results: Peptide yy, SS, Oxyntomodulin levels did not differ in obese and constipated individuals (p>0.05). GLP-1, GLP-2, Serotonin levels were found to be significantly higher in obese individuals than in constipated individuals (p<0.01).
Conclusion: In our study, high levels of GLP-1, GLP-2, and Serotonin, which have conflicting results in the literature, and positive correlations between these hormones can be considered as important findings in our study.

Authors: Arslan Ahmet , olak Cemil
Published: September 2024

Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by motor and non-motor symptoms. The diagnosis and management of PD have been significantly impacted by recent advancements in epidemiology, genetics, biomarkers, and therapeutic approaches.
This study aimed to identify potential risk factors for PD and assess their contribution to PD risk using the Explainable Boosting Machines (EBM) model, a machine learning approach. The dataset utilized in this research, accessible to researchers, comprised 2105 individuals and included 32 clinical and laboratory predictors across various categories, along with a response feature indicating PD diagnosis (yes/no). Statistical analyses, such as the Mann-Whitney U and Pearson chi-square tests, were conducted to determine significant differences between PD diagnosis groups.
The study identified several predictors as significantly different between the groups, including age, sleep quality, diabetes, depression, tremor, rigidity, bradykinesia, postural instability, and scores from assessment scales like UPDRS, MoCA, and Functional assessment. The EBM model effectively classified PD cases, demonstrating high accuracy, sensitivity, specificity, AUROC, and positive-negative predictive values. The "UPDRS" score emerged as the most influential predictor in the model, with higher scores indicating an increased risk of PD.
Future research, with more samples and predictors, can delve deeper into the interaction of these predictors and explore the potential for developing targeted interventions for PD prevention and management.

Ethical hacking and vulnerability testing represent critical components of modern cybersecurity strategies, aimed at proactively identifying and mitigating potential security threats within organizational systems and networks. Ethical hacking, also known as penetration testing, involves authorized attempts to exploit vulnerabilities in systems, applications, or networks, mirroring the tactics of malicious actors. This proactive approach allows organizations to uncover weaknesses before they are exploited by cybercriminals, thereby strengthening overall security posture. Vulnerability testing complements ethical hacking by systematically assessing systems for known vulnerabilities and configuration errors, providing insights into areas requiring remediation. Together, these practices enable organizations to assess, prioritize, and address security risks effectively, safeguarding sensitive data, maintaining regulatory compliance, and preserving business continuity. This article explores the principles, methodologies, and benefits of ethical hacking and vulnerability testing, emphasizing their role in enhancing cybersecurity resilience in an increasingly interconnected digital landscape.

Published: September 2024

Surveillance cameras have become a primary tool for monitoring human movement and preventing unwanted or unintended activities. In today's world, security management professionals increasingly rely on video surveillance to combat crime and mitigate incidents that could adversely affect society. The number of surveillance camera installations has dramatically increased in both the private and public sectors, serving to monitor public activities effectively. Video surveillance is considered one of the most efficient methods for ensuring security. Installing a surveillance camera allows the captured footage to be transmitted to security personnel; however, merely having video footage is insufficient for identifying abnormal activities. To effectively analyze this footage, it is essential to integrate an intelligent system.This paper aims to design and implement an Intelligent Video Analytics Model (IVAM), also known as the Human Object Detection (HOD) method, for analyzing and detecting video-based anomalies and abnormal human activities. IVAM can be deployed alongside surveillance cameras in various public locations such as Institutions, airports, hospitals, shopping malls, and railway stations, allowing for the automatic identification of unusual events. The IVAM was experimented with using MATLAB software, and the results were thoroughly verified. The performance of IVAM was assessed by comparing the obtained results with those from existing approaches, demonstrating that IVAM outperforms contemporary methods concerning accurate anomaly detection, lower error rates, and higher classification accuracy.
PR179-22600-R03 Evaluation of High Flow Sampler Technologies
Authors: Vaughn Tim
Published: September 2024

Operators may be obligated to measure certain emission sources for regulatory, reporting, or internal environmental and/or maintenance programs. high-flow samplers remain the most useful and accurate tool for direct measurement of fugitive and vented emissions in the field. Certain regulated sources require periodic measurement with a high-flow sampler; thus, their use is likely to continue even as new alternative technologies mature. Several new samplers are currently available commercially and development work on prototype units is ongoing. This report will describe the performance and user experience during a battery of tests performed in both laboratory and field-like settings. Two commercial units (AddGlobe GFM 2.0, and Semtech HiFlow 2) and one prototype unit (CSU OS-HFS V2) were tested.

Background: Uric acid is the end result of the metabolism of purines in the form of nucleoproteins, which are one component of nucleic acids found in the nuclei of body cells. Celery boiled water containing apiin and apigenin is believed to reduce uric acid levels naturally without causing side effects. This study aims to examine the effect of celery boiled water on reducing uric acid levels in the elderly. Purpose of the study: The purpose of this study was to identify the effect of giving celery boiled water on reducing uric acid levels in the elderly in Tanjung Alam Village. Methods: The study used pre-experiments with One Group Pretest Posttes design. Sampling technique with simple random sampling technique. The number of samples was 66 elderly people. Results: The results of statistical analysis using the Paired T-Test test. The results of the Paired T-test test on 66 elderly people showed a decrease in uric acid levels with a p-value of 0.000 (p <0.05). This shows that there is an effect of celery boiled water on reducing uric acid levels in the elderly. Conclusion: Based on the results of the study, there is an effect of giving celery boiled water on reducing uric acid levels in the elderly. Giving this therapy can be used to reduce uric acid levels in the elderly by doing it regularly with 200 cc every morning.

The nature of the infestation of cardamom scale (Aulacaspis elettaria Joshi & Nafeesa) on small cardamom [Elettaria cardamomum (L.) Maton] was illustrated. The percentage of infestation and pest density of A. elettaria in the cardamom hill reserves, Kerala, during 2021-2023 were recorded, respectively as 22.4% and 9.6 female scales/ 5 cm length of the pseudostem portion. Lower infestation and higher reduction levels in pest density were reported in plants treated with spiromecifen 22.9 SC (0.7 ml/ l) followed by spinetoram 11.7 SC (0.4 ml/ l), quinalphos 25 EC (2 ml/ l) and thiamethoxam 25 WG (0.2 g/ l). Among the botanicals tested, infestation percentage was reduced and a considerable decline in pest density (30%) was also noticed on plants treated with neem seed kernel extract (5%). The importance of integrated pest management, including the introduction of natural enemies was discussed.
