Published: October 2023

Background: Pain is an obnoxious stimulus usually triggered by stressors that can affect homeostasis. The inability to sense pain is usually connected to abnormal fluctuations in normal body functions, leading to shortened life expectancy. Purpose: This study aimed to assess the effects of Lawsonia inermis, Waltheria indica, Moringa oleifera and Nigella sativa on hematology, electrocardiography, and blood pressure in Wistar rats experimentally exposed to acute pain. Methods:21 Adult female rats were divided into (1-7) of three rats each. Group 1 (negative control), group 2 (positive control), group 3 (Lawsonia inermis at 200 mg/kg), group 4 (Waltheria indica at 200 mg/kg), group 5 (Nigella sativa at 200 mg/kg), group 6 (Moringa oleifera at 200 mg/kg), and group 7 (Diclofenac at 10 mg/kg). Rats were dosed for 14 days, after which pain was induced. Result: The extracts showed non-significant increases in most hematological parameters, including PCV, RBC, and WBC counts, compared to positive controls. The effects of the extracts on the electrocardiographic parameters were not significant. Although the extract relieved pain, the effect of acetic acid on the heart was not completely ameliorated. The results of this study showed high blood pressure in untreated rats, which could be linked to pain induction.  M. oleifera and W. indica exhibited minimal blood pressure-lowering effects. W. indica. and L. inermis showed transient blood pressure-lowering effects. Conclusion: This study concluded that the extract had a modulatory effect on hematology and a lowering effect on blood pressure and electrocardiac parameters in all treatments.

Background: Gastrointestinal parasitic diseases remain an obstacle to goat farmers in Somalia and worldwide. Purpose: This study aimed to determine the prevalence and associated risk factors of gastrointestinal parasites in goats in the Afgooye district, Lower Shabelle region, Somalia. Methods: To fulfill this study, an examination of 384 fecal samples of goats kept by smallholders was conducted. The results were achieved during the period from August 2020 to January 2022. Results: The examination of fecal samples revealed that the overall prevalence of gastrointestinal parasitic infections among goats was 71.61%. The data analysis conducted during the study indicated that there is no significant association (P > 0.05) between goat districts and gastrointestinal (GI) parasite infection. The corresponding percentage of gastrointestinal parasites in males and females was 70% and 72%, respectively. However, these variables were not significantly associated (p-value = 0.399). After categorization, age was not significantly associated with the parasitic infection status of the animal. The common parasitic infections prevalent were Nematode, Trematode, Cestode, and Protozoa types were found in different numbers. According to the flotation and sedimentation techniques, Eimeria sp. (29%) was found with higher prevalence followed by Haemonchus sp. (23%), Trichostrongylus sp. (11%), Moniezia sp. (10%), Trichuris sp. (9%), Strongyloides sp. (7%), Dictyocaulus sp. (5.2%), Nematodirus (4%), and least was Fasciola sp. (1.0%). Conclusion: This study provides comprehensive documentation on multiple GI parasites among goats in the Afgooye district, Lower Shabelle region of South-western State, Somalia, and the findings are crucial for effective farm management, especially for formulating the effective GI parasitic control vis-a-vis novel elimination strategies.

Carassius auratus is one of the potential ornamental freshwater fish in Indonesia. The potential of this fish increases along with the dominance of the colors produced during cultivation. We have demonstrated to treat differences in the light spectrum to increase the brightness of the colors. Completely randomized design with 5 treatments and 4 replications as the design i.e., (P1) negative control with no LED, (P2) positive control using white LED light and a room light intensity, (P3) red LED, (P4) green LED, and (P5) blue LED. We reported that the red LED was the light spectrum that produced the best treatment to increase the color brightness and growth of goldfish. The brightness level of the color in the P3 treatment was 63,04% as measured by Adobe Photoshop; using the M-TCF method, it was 8,94% body color, 9,37% dorsal fin, and 9,31% tail fin. Meanwhile, the best specific growth rate were found in P5 followed by P3 treatment in a row of 5,33 ± 0,66b, 3,46 ± 0,57ab, respectively. The red color spectrum produced the best pigmentation but the blue color spectrum was the best for the growth of C. auratus.

The semen quality of Gembrong goats is lower than other goats and may be related to the low concentration of testosterone hormone. Implementation of reproductive technology using prostaglandin F2α (PGF2α) hormone is beneficial to increase the testosterone hormone in Gembrong goats. This study aimed to determine the effect of PGF2α injection on increasing testosterone levels in Gembrong goats. Male Gembrong goats (n=4), aged 2.5-4 years with similar body condition scores (BCS=3) were used in this study. Goats were divided into two treatment groups (n=2). Goats in group 1 (G1) were injected intramuscularly with 1 ml PGF2α (75 μg), while those in group 2 (G2) were injected with 1 ml physiological NaCl. Semen collection was carried out 30 minutes after treatment using an artificial vagina. Testosterone levels were measured using the enzyme-linked immunosorbent assay (ELISA). The collected data was tabulated and analyzed descriptively. The results showed that the average testosterone concentration of G1 was higher than G2 with respective concentrations of 6.41 ± 0.70 and 2.81 ± 1.75 ng/ml. It was concluded that administration of PGF2α in vivo could increase testosterone concentration in Gembrong goats.

Published: October 2023

Forward-bias hole injection from 10 nm-thick p-type Nickel Oxide layers into 10 um-thick n-type Gallium Oxide in a vertical NiO/Ga2O3 p-n heterojunction leads to more than a factor of 2 enhancement of photoresponse measured from this junction. While it takes only 600 seconds to obtain such a pronounced increase in photoresponse, it persists for hours, indicating feasibility of photovoltaic device performance control. The effect is ascribed to charge injection-induced increase of minority carrier (hole) diffusion length (resulting in improved collection of photogenerated non-equilibrium carriers) in n-type beta-Ga2O3 epitaxial layers, due to trapping of injected charge (holes) on deep meta-stable levels in the material and subsequent blocking of non-equilibrium carrier recombination through these levels. Suppressed recombination leads to increased non-equilibrium carrier lifetime, in turn determining a longer diffusion length and being the root-cause for the effect of charge injection.

Published: October 2023

This study aims at the sustainable valorization of eggshells (ES) from different countries of origin in cement concrete as a cement replacement. For this purpose, sixteen different eggs from different regions across the world were selected. Firstly, the extent of uniformity in the weight and mineral content of sampled eggshells was assessed by a specific gravity test and thermogravimetric analysis (TGA), respectively. It was found that specific gravity varies between 2.02 – 2.39, having an average value of 2.20 ± 0.01, whereas the CaCO3 varies between 94.65% - 97.23%, having an average value of 96.33%. These values were a bit lower than extra-pure limestone (LS) because of having organic part and the porous structure of eggshells. Secondly, three different eggshells were selected for cement replacement in cement concrete both in the uncalcined and calcined state based on having the highest, medium, and lowest CaCO3 content, respectively. To get the calcined eggshells, the eggshells were calcined at 800oC for three hours. It was found that the strength of eggshells varies with the CaCO3, but the variation was acceptable. The calcined eggshells showed comparatively more compressive strength and were close to the LS because of free CaO and the absence of an organic part. In general, the variation in the basic properties of eggshells from different regions across the world is negligible and is suitable for use in as a cement replacement with acceptable variation in the strength.

Published: October 2023

The effects of co-addition CeO2 and SiC particles on the morphology, surface cracks, microstructure, precipitated phases and wear property of plasma beam spraying Fe55-based coatings on 1025 steel were investigated by optical microscopy (OM), scanning electron microscopy (SEM), energy-dispersive X-ray spectrometer (EDS), ultra-deep field microscope and wet sand rubber wheel friction tester, respectively. The results showed that the dendrite exhibited a directional growth pattern perpendicular to the substrate and the transitional states of microstructure with the co-addition CeO2 and SiC particles. With addition of CeO2 or SiC affected the flowability of molten steel at macro level, leading to a reduction in the liquid phase diffusion coefficient DL of Cr and C and resulted in a decrease in the G/R ratio. The dendrites changed into equiaxed grains. The main phase composition of Fe55 welding layer is Cr7C3, γ-Fe. The grain boundaries consisted mainly of a reticular eutectic structure. The worn-out uniformly surface of the Fe55+1.5 wt% SiC+0.01wt% CeO2 with Ra was 0.28 μm was smoother than that of other samples. The sub-wear mechanisms during the friction process were microploughing and microcutting. The hardness and toughness of Fe55+1.5 wt% SiC+0.01wt% CeO2 were well-matched, avoiding excessive microcutting and microplastic deformation.

Authors: Abdelrehim Tamer , Salah Maha , Fok Alex , Conrad Heather J , Chew Hooi Pin
Published: October 2023

(1) Background: OCT imaging has been used to assess enamel demineralization in dental research but is not yet developed enough to qualify as a diagnostic technique in clinics. The current capabilities of most commercial acquisition software allow for visual and qualitative assessment. There is a need for a fast and verified batch-processing algorithm for segmenting and analyzing the de-mineralized enamel. This study suggests a GUI MATLAB algorithm for processing and quantitative analysis of the demineralized enamel. (2) Methods: A group of artificially demineralized human enamels was in vitro scanned under the OCT, and ROI frames were extracted. By using a selected intensity threshold colormap, inter- (Ie) and intra- (Ia) prismatic demineralization can be segmented. A set of quantitative measurements for average demineralized depth, average line profile, and integrated reflectivity can be obtained for an accurate assessment. Real and simulated OCT frames were used for algorithm verification. (3) Results: A strong correlation between automated and known Excel measurements for the average demineralization depth was found (R² > 0.97). (4) Conclusions: OCT image segmentation and quantification of the enamel demoralization zones are possible. The algorithm can assess the future development of a real-time assessment of dental diagnostics using an oral probe OCT.
Relativistic Correction to Black Hole Entropy
Authors: Kumar Naman
Published: October 2023

In this paper, we study the relativistic correction to Bekenstein-Hawking entropy in the canonical ensemble and isothermal-isobaric ensemble and apply it to the cases of non-rotating BTZ and AdS-Schwarzschild black holes. This is realized by generalizing the equations obtained using Boltzmann-Gibbs(BG) statistics with its relativistic generalization, Kaniadakis statistics, or κ-statistics. The relativistic corrections are found to be logarithmic in nature and it is observed that their effect becomes appreciable only in the high-temperature limit suggesting that the entropy corrections must include these relativistically corrected terms while taking the aforementioned limit. The non-relativistic corrections are recovered in the κ → 0 limit.
Fostering Urban Walking: Strategies Focused on Pedestrian Satisfaction
Authors: Distefano Natalia , Leonardi Salvatore
Published: October 2023

Urban mobility and sustainable transportation are fundamental for the European Union's goal of achieving climate neutrality by 2050. The EU encourages national governments to prioritize zero-emission urban transport systems that emphasize safety, accessibility, and inclusiveness. Promoting walking plays a fundamental role in sustainable urban mobility, offering advantages such as emission reduction, better air quality, and enhanced public health. Recent research underscores the importance of creating appealing and safe pedestrian environments to encourage walking. These efforts align with the United Nations' Agenda 2030 sustainability goals, particularly Objective 11, which aims to build inclusive, safe, and sustainable cities and communities. This paper explores the factors influencing pedestrians' willingness to walk and categorizes them into four main groups: Physical Characteristics, Comfort, Safety, and Attractiveness. Significantly, the study reveals that the importance of these factors varies based on demographics, mainly the age of the users. Understanding these factors and their relative significance for pedestrian satisfaction is crucial for shaping effective policies and urban planning strategies aimed at promoting sustainable mobility. By prioritizing pedestrian satisfaction and addressing the specific needs and preferences of diverse groups, cities can create more walkable and environmentally friendly urban environments. These findings offer valuable insights for policymakers and urban planners working toward EU climate-neutral objectives and enhancing the well-being of citizens.

Published: October 2023

This paper presents the prelaunch radiometric calibration of the Ozone Monitor Suite - Nadir (OMS-N) instrument, a vital payload on the FY-3F satellite. FY-3F achieved a successful launch on August 3, 2023. The radiance calibration of the OMS-N instrument was achieved using an integrating sphere, with known exit radiance ascertained through a transferring radiometer. The calibration model incorporates six energy levels. The Solar Simulator Standard System was employed to validate the calibration results, selecting specific rows to represent varying spatial dimensions. Considering the influence of xenon lamp characteristic peaks and transmission errors during the calibration process, the average deviation remained within 2.3% for the UVIS channel, 3% for the UV1 channel, and 2.2% for the UV2 channel. Furthermore, this study analyzed the uncertainty of the radiometric calibration. The results indicated an absolute uncertainty of 2.32% for both UV1 and UV2 channels, while the VIS channel exhibited an uncertainty of 1.67%. The relative uncertainty was 1.84% for both UV1 and UV2 channels, with the VIS channel exhibiting an uncertainty of 1.45%. The obtained calibration coefficients are accurate and reliable and can be used for the inversion of product parameters, which is of great significance to the quantitative application of satellite data and the advancement of scientific research on quantitative remote sensing.

Wavelet Theories and Techniques for Brain Disease: Diagnosis and Treatmentz
Authors: Ye Shengpei
Published: October 2023

This paper first introduces the main classification of brain diseases and the main causes of these diseases. It is followed by wavelet analysis, which is a mathematical function or wave-like pattern used to transform data, which can decompose the signal into different wavelet functions, each of which is related to a specific scale or frequency. Wavelet analysis has been applied in many fields such as image processing, data analysis and engineering. In addition, wavelet is also used in the analysis of biological signals. Wavelet analysis breaks down brain signals, such as EEG or fMRI data, into various frequency components at different scales. Wavelet analysis provides time-frequency localization. Pattern recognition can be enhanced by isolating salient features in the data. Wavelet denoising can effectively separate noise from underlying brain signals. Wavelet denoising usually adopts threshold method. Wavelet analysis can enhance pattern recognition by isolating salient features in the data. Researchers can train machine learning models based on these wavelet-derived features to recognize specific patterns associated with different neurological disorders. Wavelet analysis can track these changes by continuously evaluating the frequency content of the neuroimage data over time. Through continuous efforts, wavelet theory and technology have become valuable tools in the field of neuroscience and brain disease research.

Authors: López Martínez Jorge , Féber González Déborah
Published: October 2023

El objetivo del artículo es demostrar y determinar la relación entre factores socioeconómicos y urbanos, y la generación de Sintomatologías Depresivas (SD) en la población que habita las principales veinte ciudades del país. Para ello, —en primera instancia— se hace un análisis comparativo de la presencia de SD en dos entornos: el rural y el urbano. Posteriormente, se crea el Índice Complejo de Condiciones Socioeconómicas y Urbanas (ICCSU), conceptualizado con base en el Mind the GAPS framework. La construcción del ICCSU toma en cuenta cuatro indicadores urbanos y cuatro socioeconómicos para los años 2012 y 2018-19, a partir de datos Sistema Nacional de Información Estadística y Geografía (SNIEG), del Instituto Mexicano para la Competitividad, A. C. (IMCO), y del Consejo Nacional de Evaluación de la Política de Desarrollo Social (Coneval). Finalmente, se establece un modelo de panel de datos que toma en cuenta el ICCSU y los datos de la Encuesta Nacional de Salud y Nutrición (ENSANUT). Los hallazgos revelan la existencia de una relación clara entre factores urbanos y socioeconómicos, y la SD; entre las ciudades y las personas que sufren de SD moderada a severa, a diferencia de las áreas rurales, padecimiento que se intensifica con las condiciones socioeconómicas de la población, es decir, su estrato socioeconómico, su género y la marginación urbana presente. Sin embargo, se encuentra que, en el corto plazo, las mejoras en las condiciones socioeconómicas y urbanas en las ciudades de estudio, han tenido un leve impacto sobre la disminución de la sintomatología depresiva

A rapid review módszerének kísérleti alkalmazása a nyelvtudományban. Szakirodalmi áttekintés az iskolai szövegalkotással kapcsolatos magyar nyelvű empirikus kutatásokról
Authors: Jakab Dorottya , P. Tóth Teodóra
Published: October 2023

A szakirodalmi áttekintés a tudományos kutatómunkák elengedhetetlen lépése. A hazai tudományos munkákban a hagyományos szakirodalom-feltárási eljárások, a nemzetközi szakirodalomban azonban a részletesebb áttekintésre alkalmas gyakorlatok alkalmazása jellemző. A systematic review és rapid review az orvostudomány területéről származó, szigorú módszertannal rendelkező áttekintési mód, amely egy adott témához kapcsolódó tudományos munkák feltárását és feldolgozását teszi lehetővé. Mivel a hazai gyakorlatban nem jellemző ilyen áttekintések készítése, a tanulmány elsődleges célja, hogy a systematic review és a rapid review módszertanát ismertesse. Emellett a tanulmány bemutat egy olyan kísérletet is, amely a rapid review módszerét magyar nyelvű szakcikkek áttekintésében alkalmazza. Az áttekintés témája a szövegalkotás tanítása a közoktatásban. A kísérlet eredményei rámutatnak arra, miért lenne fontos egyre több szisztematizált áttekintés készítése magyar nyelven is.
Marine bioinvasion risk : review of current ecological models
Authors: Altman Safra , Powell Krystyna , Kress Marin
Published: October 2023

This special report describes the first phase of developing an ecological model to inform marine bioinvasion risks in the United States. The project responds to the needs of the US Army Corps of Engineers (USACE) Aquatic Nuisance Species Research Program, or ANSRP, which addresses all problematic invasive aquatic species affecting the nation’s waterways, infrastructure, and associated resources, and the needs of the USACE navigation and dredging programs. Multiple port-deepening studies are either in progress or under consideration, and all must address ecological risk. Understanding whether and how increased dredging contributes to increased marine bioinvasion risk allows risk mitigation during early planning phases. Considering the potential impacts of future environmental change, such as changing sea level, ocean temperature, and ocean chemistry, will further strengthen planning for marine bioinvasion risk. Therefore, this special report documents current ecological modeling approaches to marine bioinvasion risk models and identifies models that incorporate shipping as a vector. The special report then presents a conceptual model and identifies historic vessel position data from the Automatic Identification System, or AIS, now available for most commercial and some recreational vessels around the United States, as a key source for future model development and testing.

Published: October 2023

Objective: Posterior full-endoscopic cervical foraminotomy/discectomy (PECF) is used to treat medically intractable cervical radiculopathy. PECF has many potential advantages; however, despite its minimally invasive nature, complications of PECF are possible, including hemorrhage, infection, injury to neural tissue, damage to the facet joint and musculature, loss of cervical lordosis, and subsequent progression to cervical kyphosis. We examined complications following PECF and reviewed the relevant literature.Methods: We retrospectively reviewed 101 patients who underwent PECF for either disc herniation (DH, 59 patients) or foraminal stenosis (FS, 42 patients). After surgery, the patients were encouraged to ambulate and were discharged 2–3 days later without the use of a neck collar. Events occurring during hospitalization were documented in the hospital information system. Patients were followed-up for a mean period of 21±26 months (range, 1–110 months).Results: Clinical parameters improved from 1 month postoperatively and were maintained throughout the follow-up period, with no significant differences between the DH and FS groups (p>0.05). Complications occurred in 14 patients (14%) with no significant difference between the DH (8 of 59, 14%) and FS (6 of 42, 14%) groups (p>0.05). The most common complication was dural tear, followed by motor weakness, sensory changes, hematoma collection, incomplete decompression, reoperation, and wrong-level surgery. Two patients underwent reoperation due to symptomatic hematoma collection and symptom recurrence 3 years postoperatively.Conclusion: The incidence of complications following PECF was 14%. Although most were transient, an understanding of both reported and unreported complications, along with thorough preparation, could reduce the occurrence of PECF-associated complications.
Single- and Multiple-Segment Percutaneous Pedicle Screw-Rod Fixation: Complications and Bailout Strategies
Authors: Agrawal Aniruddh , Anand Neel
Published: October 2023

Percutaneous pedicle screw fixation systems have improved significantly since their introduction in 2001. A new surgeon’s learning curve is usually 70 cases when defined by the complication rate and not by a specific time to insertion. An appropriate preoperative assessment is important when considering a percutaneous pedicle screw approach, and high complication rates are linked to patients above the age of 65 and the need for multilevel fixation. A surgeon should be wary of performing surgery at the wrong site; therefore, meticulous documentation should be carried out, and the operative level should be confirmed. During surgery, attention should be paid to positioning the patient and varying the location of the skin incision depending on the patient’s obesity. Penetration of visceral structures and vessels due to guidewire insertion is not an uncommon complication. Anterior penetration of the guidewire by as little as 5 mm can cause significant sympathetic chain dysfunction. Guidewire removal should also be prevented during tapping of the screw hole and removal of the Jamshedi needle. This procedure has a high complication rate in unexperienced hands and should be performed by surgeons after adequate cadaver training. Surgeons should initially attempt only single-level fixations and then later on move to more complex multilevel fixations and deformity corrections.

Published: October 2023

Objective: This study investigated the clinical and radiological outcomes of lumbar spinous process-splitting laminectomy (LSPSL) performed to treat lumbar spinal stenosis at a single institution in Korea. Methods: A retrospective review was conducted of patients who underwent LSPSL for lumbar spinal stenosis between June 2020 and February 2022, with a minimum 1-year follow-up. Clinical outcomes were assessed using the visual analogue scale (VAS), Oswestry Disability Index (ODI), European quality of life - 5 dimensions - 5 levels (EQ-5D-5L), European quality of life VAS (EQ-VAS), and modified MacNab criteria. One year after surgery, radiological outcomes were evaluated through computed tomography scan to assess the spinolaminar bone union rate and patterns.Results: Out of 38 patients, data from 30 patients (male:female = 17:13) and 36 surgical levels were analyzed. The mean age was 67 years (range, 46–88 years). The preoperative mean leg VAS score and ODI significantly decreased at the 1-year postoperative follow-up (leg VAS, 6.6–3.8; p = 0.001; ODI, 19.3–10.9, p = 0.006). The EQ-5D-5L index and EQ-VAS also significantly improved (0.52–0.77, p < 0.001; 50.8–67.1, p = 0.018; respectively). Using the modified MacNab criteria, the study reported excellent and good outcomes in 80% of patients at the 1-year follow-up, with no serious complications observed. The overall spinolaminar union rate was 77.8% (complete union, 58.3%; partial union 19.4%).Conclusion: LSPSL was found to provide favorable clinical outcomes and a satisfactory rate of posterior bony structure restoration for lumbar spinal stenosis, making it a feasible treatment option.
