Published: September 2024

Cultivation of Litopenaeus vannamei shrimp is an important fishery commodity in Indonesia. Providing the right amount of feed is crucial for optimal shrimp growth. The amount of feed given greatly depends on the measurement of shrimp length. The aim of this research is to develop an image processing-based program for measuring the length of Litopenaeus vannamei shrimp using the YOLOv8 algorithm through Euclidean distance calculation. YOLOv8 detects shrimp objects within a defined distance. The obtained images are used to estimate the length using Euclidean distance calculation. The results show that this program can detect and measure shrimp length with an accuracy of 96.8%. Based on the detected shrimp length, the program can calculate the Mean Body Weight (MBW) and Feeding Ratio (FR) with an average error below 5%.

Published: September 2024

Abstract
The article deals with the development of standards and library information systems in Croatia from the late 1970s to 2023. Despite the turmoil of the dissolution of former Yugoslavia, the National and University Library in Zagreb (NUL) was able to continue its operations and was central to initiatives aimed at adapting national needs to international developments until the early 2000s, when it switched to a commercial system. The publication of the National Content Standard in 2021 has given the NUL the opportunity to assume again its central role in the Croatian bibliographic ecosystem.

Abstract
Mechanomyography (MMG) may be used to quantify very small motor responses resulting from muscle activation, voluntary or involuntary. The purpose of this study was to investigate the MMG mean peak amplitude (MPA) and area under the curve (AUC) and the corresponding mechanical responses following delivery of transcranial magnetic stimulation (TMS) to the knee extensors. Fourteen adults (23 ± 1 years) received single TMS pulses at intensities from 30–80 % maximum stimulator output to elicit muscle responses in the relaxed knee extensors while seated. An accelerometer-based sensor was placed on the rectus femoris (RF) and vastus lateralis (VL) muscle bellies to measure the MMG signal. Pearson correlation revealed a positive linear relationship between MMG MPA and TMS intensity for RF (r=0.569; p<0.001) and VL (r=0.618; p<0.001). TMS intensity of ≥60 % maximum stimulator output produced significantly higher MPA than at 30 % TMS intensity and evoked measurable movement at the knee joint. MMG MPA was positively correlated to AUC (r=0.957 for RF and r=0.603 for VL; both p<0.001) and knee extension angle (r=0.596 for RF and r=0.675 for VL; both p<0.001). In conclusion, MMG captured knee extensor mechanical responses at all TMS intensities with the response increasing with increasing TMS intensity. These findings suggest that MMG can be an additional tool for assessing muscle activation.

Abstract

Objectives
The performance of synovial fluid biomarker D-lactate to diagnose septic arthritis (SA) and differentiate it from crystal-induced arthritis (CA), other non-infectious rheumatic joint diseases (RD) and osteoarthrosis (OA) was evaluated.

Methods
Consecutive adult patients undergoing synovial fluid aspiration due to joint pain were prospectively included in different German and Swiss centers. Synovial fluid was collected for culture, leukocyte count and differentiation, detection of crystals, and D-lactate concentration. Youden’s J statistic was used to determine optimal D-lactate cut-off value on the receiver operating characteristic (ROC) curve by maximizing sensitivity and specificity.

Results
In total 231 patients were included. Thirty-nine patients had SA and 192 aseptic arthritis (56 patients with OA, 68 with CA, and 68 with RD). The median concentration of synovial fluid D-lactate was significantly higher in patients with SA than in those with OA, CA, and RD (p<0.0001, p<0.0001 and p<0.0001, respectively). The optimal cut-off of synovial fluid D-lactate to diagnose SA was 0.033 mmol/L with a sensitivity of 92.3 % and specificity of 85.4 % independent of previous antimicrobial treatment. Sensitivity and specificity of synovial fluid leukocyte count at a cut-off of 20,000 cells/µL was 81.1 % and 80.8 %, respectively.

Conclusions
Synovial fluid D-lactate showed a high performance for diagnosing SA which was superior to synovial fluid leukocyte count. Given its high sensitivity and specificity, it serves as both an effective screening tool for SA and a differentiator between SA and RD, especially CA.
Sanskrit scholars in Nazi Germany
Authors: Vigasin Alexei 
Published: September 2024

Abstract
German Sanskrit scholars from the beginning of the 19th century addressed the problem of the kinship between the ancient Germans and Aryans – while romantic patriotism was gradually replaced by militant nationalism. After World War I racism, widespread not only in Germany, but also in other Western countries, became the essential element of the ideology of National Socialism. In the 30s all German scholars were forced to make compromises under the pressure of totalitarian power. However, only a few Sanskrit scholars can be called active supporters of the regime. They have different motives: from the frank careerism of Walter Wüst to the cautious conformism of Ludwig Alsdorf. Religious scholar Jakob Wilhelm Hauer claimed to be the prophet of the “Aryan Worldview”, and Bernhard Breloer was passionate about plans of building a new social and political system, in which the individual is completely subordinate to the state. The anti-Semitic policies and political persecutions of the Nazi period had disastrous consequences for classical German Indology.

Published: September 2024

Abstract
This study investigates the influence of post-oxidation duration on the wear performance and microstructural features of AISI 4140 steel subjected to nitrocarburizing followed by post-oxidation. For this aim, the quenched and tempered AISI 4140 samples were nitrocarburized (NC) and post-oxidized (PO) at various times (45–180 min) under low vacuum. Microstructural features were investigated using optical microscopy, scanning electron microscope (SEM), energy-dispersive X-ray spectrum analysis (EDS), X-ray diffraction (XRD) analysis, and microhardness test. Wear behavior was evaluated using a ball-on-disk tribometer. Experimental results showed that the structures consisting of nitride layer (ε-Fe2–3N) and γ′-Fe4N + iron oxide (Fe3O4) were obtained at the top surfaces of the samples. Increasing post-oxidation times resulted in a notable enhancement in the thickness of the Fe3O4 layer. The growing Fe3O4 layer has induced the closing of micro porosities for further post-oxidizing times, leading to decreased surface roughness of the samples. It was determined that the post-oxidation times have no significant effect on the hardness profiles of NC + PO samples. The highest (0.375) and lowest (0.276) mean coefficient of friction was obtained in the post-oxidation times of 150 and 180 min, respectively. The best wear rate was obtained in the post-oxidized sample for 150 min.
Ionic surfactants critical micelle concentration prediction in water/organic solvent mixtures by artificial neural network

Published: September 2024

Abstract
Critical micellar concentration (CMC) is a key physicochemical property of surfactants used to study their behaviour. This property is affected by factors such as temperature, pressure, pH, the type of organic solvent/water mixture, the chemical structure of the surfactants and the presence of electrolytes. Most of the existing studies in the literature have predicted the CMC under fixed conditions based on the chemical parameters of the surfactant. In this study, a machine learning approach using artificial neural network (ANN) models was used to estimate the CMC of some ionic surfactants. These models considered variables defining both the organic solvent-water mixture (T, molecular weight, molar fraction and log P) and the chemical structure of the surfactant (number of atoms of each element). A database consisting of a total of 258 CMC values for 10 ionic surfactants was collected from the literature. The ANN architecture consisting of an input layer with 12 neurons, an intermediate layer with 25 neurons and one neuron in the output layer is proposed. According to the results, the normalized ANN models provided the best statistical adjustments for the CMC prediction. These ANN models could be a promising method for CMC estimation.

Penelitian dilaksanakan pada tanggal 15 Maret 2023 sampai 23 Mei 2023 di KMN. Audy Maega Dalle berpangkalan di Pangkalan Pendaratan Ikan (PPI) Oeba Kupang. Analisis deskriptif digunakan mendeskripsikan tentang teknik penangkapan dengan alat tangkap purse seine, pada waktu pelingkaran alat tangkap, penarikan tali kerut dan penggunaan alat bantu lampu pengumpul ikan. Pengaruh aspek teknis pukat cincin terhadap hasil tangkapan. Yaitu lama pelingkaran sebesar 34,12 %. Lama penarikan tali kerut sebesar 40,48%. Lama waktu penyinaran sebesar 0,38%, artinya setiap penambahan 1 menit dalam dua perlakuan tersebut akan terjadi penurunan hasil tangkapan sedangkan pengaruh penyinaran apabila berkurang 1 menit akan terjadi penurunan hasil tangkapan. Dengan demikian, semakin cepat durasi waktu pelingkaran jaring, waktu penarikan tali kerut dan semakin lama durasi waktu penyinaran lampu pengumpul ikan, maka hasil tangkapan ikan yang diperoleh akan semakin besar.
Identifying Barriers and Facilitators to Active Travel Infrastructure Usage Amongst Under-Represented Population Groups in the United Kingdom: A Rapid Systematic Review
Authors: Malden Stephen , McDougall Craig , Wendelboe Nelson Charlotte , Carroll-Monteil Emma , Jepson Ruth 
Published: September 2024

Utilising active travel has the potential to positively impact health. Research shows that certain members of society may be less likely to undertake active travel than others, particularly individuals belonging to marginalised population groups such as ethnic minorities and people with disabilities. The aim of this rapid systematic review was to assess the barriers and facilitators to active travel amongst marginalised groups in the United Kingdom. Electronic databases were searched from inception to October 2022. All primary study designs were deemed eligible for inclusion if they investigated either barriers or facilitators to active travel amongst a marginalised population group within the UK. Twelve studies met inclusion criteria encompassing participants from an ethnic minority background, physical disability or a learning disability. Safety concerns were identified as a barrier for each group. Infrastructural barriers were apparent for people with a physical disability. Bike ownership or lack of bike-riding knowledge was a barrier for ethnic minorities. Facilitators identified were provision of recourses in the form of bicycles and training for ethnic minorities, while improved independence and perceived health benefits facilitated active travel amongst people with disabilities. Overall, the included studies were deemed to be of a high risk of bias. There is a lack of high-quality research in this area in the UK context, and future studies should aim to identify ways to improve access to active travel for ethnic minorities, people with disabilities, in addition to other marginalised groups who are currently not represented in the existing literature.
Sexual and gender minority youth in Canada: An investigation of disparities in positive mental health
Authors: Hajo Sonia , Capaldi Colin A. , Liu Li 
Published: September 2024

Abstract
Objectives
While studies indicate that 2SLGBTQ + youth are more likely to experience negative psychological outcomes compared to their heterosexual and cisgender peers, less is known about the positive mental health (PMH) of 2SLGBTQ + youth in Canada. To fill this gap, we investigated disparities in PMH by self-reported sexual attraction among 15‒17-year-olds and gender modality among 12‒17-year-olds.

Methods
We analyzed data from youth respondents in the 2019 Canadian Health Survey on Children and Youth. We obtained estimates of average life satisfaction and high self-rated mental health, happiness, autonomy, competence, and relatedness for youth with an exclusively heterosexual attraction and youth with a minority sexual attraction (those exclusively attracted to the same gender, and those attracted to both females and males), and for cisgender and gender minority youth. Regression analyses were conducted to test for disparities on each PMH outcome.

Results
Compared with exclusively heterosexual youth, sexual minority youth reported lower life satisfaction and were less likely to report high self-rated mental health, happiness, autonomy, competence, and relatedness. Significant disparities were more consistently found for youth attracted to both females and males than youth exclusively attracted to the same gender. Gender minority (versus cisgender) youth also reported lower average life satisfaction and were less likely to report high self-rated mental health, happiness, autonomy, competence, and relatedness.

Conclusion
Although this study provides evidence for the presence of disparities in PMH, its strength-based focus on PMH also documents the presence of well-being among many sexual and gender minority youth in Canada.

Authors: Kliuchagina Yu. I. , Zeynalova P. A. , Gromova E. G. , Valiev T. T. 
Published: September 2024

Background. Renal failure (RF) is the most common complication of multiple myeloma (MM), and severe RF requiring hemodialysis is diagnosed in 2–4 % of cases. RF associated with MM is potentially reversible. Severe RF requiring hemodialysis is associated with low overall survival rates, increased risk of complications and early death, low quality of life for patients. Aim. To analyze treatment results of newly diagnosed MM patients with severe RF requiring hemodialysis. Materials and methods. We analyzed data of 39 patients with newly diagnosed MM and severe RF requiring hemodialysis (CKD-EPI < 15 mL/min/1.73 m2) who underwent combination therapy at the N.N. Blokhin National Medical Research Center of Oncology between January 2000 and December 2020. Results. As induction therapy, 25 (64.1 %) patients received bortezomib-based regimens: 13 (33.3 %), VCD (bortezomib + cyclophosphamide + dexamethasone); 12 (30.8 %), VCP (bortezomib + cyclophosphamide + prednisolone); 14 (35.9 %) patients received chemotherapy: VAD (vincristine + doxorubicin + prednisolone), VMCP (vincristine + melphalan + cyclophosphamide + prednisolone), CD (cyclophosphamide + prednisolone). Seven (17.9 %) patients underwent high-dose chemotherapy followed by autologous hematopoietic stem cell transplantation, 5 (71.4 %) patients from this group received bortezomib-based regimens (VCD, VCP), and 2 (28.6 %) – chemotherapy (VAD). After induction therapy, 19 (48.7 %) patients achieved objective hematologic response, and 23 (59 %) patients achieved objective renal response. The use of bortezomib-based induction therapy significantly increased the likelihood of achieving both hematologic and renal responses (p = 0.021 and p = 0.049, respectively) compared with the use of regimens without bortezomib. With a median follow-up of 19 months (95 % confidence interval 1–64 months), median progression-free survival was 15 months (95 % confidence interval: 8–26 months), median overall survival was 29 months (95 % confidence interval: 9–47 months). Multivariate analysis showed statistical significance of the effect of receiving autologous hematopoietic stem cell transplantation on progression-free survival and overall survival (p = 0.015 and p = 0.018, respectively). Conclusion. Using bortezomib-based regimens in newly diagnosed MM patients with severe RF requiring hemodialysis is associated with greater likelihood of achieving both hematologic and renal responses. Performing autologous hematopoietic stem cell transplantation improves progression-free survival and overall survival.

Published: September 2024

Background. Primary immune thrombocytopenia (ITP) is an orphan disease characterized by decreased platelet count in the peripheral blood which in some cases can cause bleeding of varying severity. Currently, the use of thrombopoietin receptor agonists (TPO-RAs) is recommended as the second line therapy for ITP as it allows to achieve high platelet response (PR), including complete, in 73 % of cases of chronic ITP and in 87 % of cases of newly diagnosed disease. The mechanism of action differs for different TPO-RAs. Given this fact, in cases of resistance or intolerance to therapy with one TPO-RA, attempts are made to switch to another. The effectiveness of this approach for overcoming ITP resistance varies from 50 to 93 % according to various publications. Aim. To assess the ability to achieve and maintain PR by switching from one TPO-RA to another in cases of resistance to the previous TPO-RA used in the second or subsequent lines of therapy. Materials and methods. The analysis included 59 patients who were resistant (in 2 cases intolerance was also noted) to TPO-RA therapy (received after standard therapy) who were prescribed TPO-RA treatment with a different mechanism of action: switch from romiplostim to eltrombopag (25 patients) or vice versa (34 patients). Both groups were comparable in terms of demographic characteristics and median platelet level at the time of TPO-RA switching. Results. PR was obtained in 76 % of cases, including complete response in 54 %, as a result of switching from one TPO-RA to another in 59 patients. Among 34 patients switched from eltrombopag to romiplostim, PR was achieved in 31 (91 %) patients, including complete response in 22 (65 %). Romiplostim was switched to eltrombopag in 25 patients, PR was achieved in 14 (56 %) with complete response in 10 (40 %). Conclusion. The study showed that PR can be achieved and maintained through switching from one TPO-RA to an alternative.

Authors: Rasheed Zahraa Raad , Abd Ahmed Najem , Hassan Karim H 
Published: September 2024

Purpose: Zinc Oxide Nanoparticle (ZnO NPs) production has become more common because of the benefits of the green strategy, which include its ease of use, environmental friendliness, and cheap operating costs. In order to accomplish the goal of green chemistry, the green synthesis process also uses safe solvents like water and ethanol. ZnO NPs are among the metal oxide-NPs used in antibacterial and bioremediation applications.
Materials and Methods: Energy Dispersive X-ray spectroscopy (EDX), Fourier Transform Infrared spectroscopy (FT-IR), X-Ray Diffractometer (XRD), and Field Emission Scanning Electron Microscopy (FESEM) were used to analyze the green-produced ZnO NPs.
Results: ZnO nanoparticles have an average size of 22.89 nm, which is corroborated by FESEM pictures, indicating that the particles are tiny. The excellent purity of ZnO NPs has been confirmed by EDX data. The antibacterial activity of ZnO NPs was assessed against a few dangerous pathogens. Zinc oxide nanoparticles were shown to have an interesting antibacterial action against both gram-positive and gram-negative bacteria at micromolar concentrations because they exhibit the maximum diameter of inhibition zone at concentrations 100 mg/ml of S. aureus, E. coli, K. pneumonia, Acintobacret spp, S. fecalis reaching (27,19,18,17, and 14) mm, respectively while S. pneumonia were resistant.The ZnO NPs recorded at a concentration of 12.5 mg/ml lowest areas of the inhibition zone against the same isolates reaching (16, 11, 11, 12, and 10) mm while S. pneumonia were resistant, respectively, as well.
Conclusion: ZnO NPs, since they have excellent antibacterial properties, and are biocompatible, they will open up a new line of inquiry for antibacterial agent research because they are stable, nontoxic, and harmless.
