BACKGROUND: The differential diagnosis of peripheral nervous system damage depends on a thorough collection of history, comprehensive assessment of clinical manifestations, and dynamic examination of the patient. This article describes a clinical case of acute polyneuropathy in a young child, which began with gastrointestinal symptoms and bilateral facial neuropathy.
CLINICAL CASE DESCRIPTION: The article presents a case of a child with an atypical course of acute polyneuropathy, which began with bilateral facial neuropathy combined with gastrointestinal complaints and pain syndrome. Features of the clinical presentation of the disease required extended laboratory and instrumental testing. Protocols for instrumental verification of diagnosis included nerve conduction studies examining neural conduction and axonal excitability of the affected facial nerve and the healthy side. Additionally, the functional status of the peripheral nerves in the upper and lower limbs was assessed. Polyneuropathic alterations revealed through nerve conduction studies confirmed diagnostic lumbar puncture to determine the presence of neuroinfectious processes. Magnetic resonance imaging of the brain, brachial, and lumbosacral plexuses using intravenous contrast showed the nature and prevalence of a lesion. Based on the overall clinical, laboratory, and instrumental examination data of the patient, “acute inflammatory demyelinating polyneuropathy” was diagnosed; timely etiopathogenetic treatment was initiated.
CONCLUSION: In children, the course of a neuroinfection may be atypical. Sometimes, when dissociating the clinical manifestations of the disease from the results of a standard laboratory and instrumental test, expert diagnostic techniques should be used for differential diagnosis purposes.
Post-COVID asthenia, sarcopenia and muscle weakness among geriatric patients
Authors: Belopasov Vladimir V. , Veselova Daria K.
Published: June 2024

Sarcopenia, asthenia, and motor activity restriction are common among geriatric patients in the post-COVID period. The SARS-CoV-2 virus triggers a cytokine storm in the human body and induces a direct viral effect on skeletal muscles. Manifestations of post-acute sequelae of COVID-19 (PASC) can include organ and system dysfunction, asthenia, muscle weakness, dyspnea, chest pain, cognitive impairment, depression, anxiety, and sleep disorders. Hypoxemia, comorbidity, and prolonged inactivity contribute to changes in the structure and functionality of the muscular fibers. One of the recent studies is ALMI-index, which indicates that a decrease in muscle mass of the upper and lower extremities may cause functional limitations in patients with long-COVID conditions. Rehabilitation of patients with post-COVID syndrome involves daily exercise with weights, considering load tolerance; mandatory medication; and nutritional and psychological support.

Published: June 2024

Las evaluaciones de riesgos del cambio climático y la variabilidad climática generalmente se centran en ciclones tropicales debido al peligro potencial para la sociedad humana, especialmente en áreas costeras urbanas como las que se encuentran a lo largo del Golfo de México. La frecuencia de este fenómeno natural depende de la confluencia de diferentes factores dinámicos (divergencia del viento y vorticidad relativa) y termodinámicos (contenido de agua atmosférica y temperatura de la superficie del mar). Las oscilaciones atmosféricas a gran escala modulan estos factores e influyen en la formación y el desarrollo de ciclones tropicales (TC), produciendo importantes impactos sociales y económicos. Este trabajo explora la relación entre la Oscilación Maden-Julian (MJO) y El Niño-Oscilación del Sur (ENSO) con respecto a la ciclogénesis tropical del Golfo de México, utilizando series temporales y análisis de estudios de casos sinópticos, con el fin de contribuir a futuras evaluaciones de riesgos en estas zonas costeras. Los resultados indican que las frecuencias de OMJ y ENSO están presentes en la divergencia del viento y la vorticidad relativa, el contenido de vapor de agua atmosférico y la temperatura de la superficie del mar. Las condiciones concurrentes de ENOS de fase fría y OMJ de fase convectiva benefician la formación de TC, mientras que las condiciones de ENOS de fase cálida inhiben la formación de TC y afectan el ciclo de OMJ. Los análisis sinópticos de los estudios de caso muestran que la divergencia del viento y las anomalías en el contenido de agua atmosférica dominan el comportamiento de los TC.

Objectives: The main aim of this article was to analyze the emotional levels of anxiety amongst health professionals employed in prisons during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic. Material and method: This descriptive, cross-sectional study was conducted by means of a validated anxiety questionnaire answered by 100 clinical nurses and nursing assistants residing in Spain and working in prisons. Alongside the demographic information, the test included 14 items related to anxiety levels. The questionnaire turned out to be highly reliable after carrying out an analysis with a Cronbach´s alpha of 0.935, demonstrating high reliability. Results: Over one third of health participants presented severe anxiety levels, with a greater impact on women than on men. The situation in centers for the elderly appears to be more tense and complex than in prisons, although the latter are far more overcrowded. However, both institutions show common factors, such as the vulnerability of their populations and a possible explosive outbreak, which would exceed the resources available in such institutions. Discussion: The significant levels of anxiety that nursing professionals showed in the study make it necessary to implement measures to avoid more serious future consequences in the medium and long term.

Published: June 2024

In his beautiful book, Consilience: The Unity of Knowledge, the eminent biologist Edward O Wilson, advocates the need for integration and reconciliation across the sciences. He defines consilience as “literally a ‘jumping together' of knowledge with a linking of facts … to create a common groundwork of explanation”. It is the premise of this paper that as much as basic biomedical research is in need of data generation using the latest available techniques– unifying available knowledge is just as critical. This involves the necessity to resolve contradictory findings, reduce silos, and acknowledge complexity. We take the cornea and the lens as case studies of our premise. Specifically, in this perspective, we discuss the conflicting and fragmented information on protein aggregation, oxidative damage, and fibrosis. These are fields of study that are integrally tied to anterior segment research. Our goal is to highlight the vital need for Wilson's consilience and unity of knowledge which in turn should lead to enhanced rigor and reproducibility, and most importantly, to greater understanding and not simply knowing.

AIM: To explore the effect of silent information regulator factor 2-related enzyme 1 (SIRT1) on modulating apoptosis of human lens epithelial cells (HLECs) and alleviating lens opacification of rats through suppressing endoplasmic reticulum (ER) stress.
METHODS: HLECs (SRA01/04) were treated with varying concentrations of tunicamycin (TM) for 24h, and the expression of SIRT1 and C/EBP homologous protein (CHOP) was assessed using real-time quantitative polymerase chain reaction (RT-PCR), Western blotting, and immunofluorescence. Cell morphology and proliferation was evaluated using an inverted microscope and cell counting kit-8 (CCK-8) assay, respectively. In the SRA01/04 cell apoptosis model, which underwent siRNA transfection for SIRT1 knockdown and SRT1720 treatment for its activation, the expression levels of SIRT1, CHOP, glucose regulated protein 78 (GRP78), and activating transcription factor 4 (ATF4) were examined. The potential reversal of SIRT1 knockdown effects by 4-phenyl butyric acid (4-PBA; an ER stress inhibitor) was investigated. In vivo, age-related cataract (ARC) rat models were induced by sodium selenite injection, and the protective role of SIRT1, activated by SRT1720 intraperitoneal injections, was evaluated through morphology observation, hematoxylin and eosin (H&E) staining, Western blotting, and RT-PCR.
RESULTS: SIRT1 expression was downregulated in TM-induced SRA01/04 cells. Besides, in SRA01/04 cells, both cell apoptosis and CHOP expression increased with the rising doses of TM. ER stress was stimulated by TM, as evidenced by the increased GRP78 and ATF4 in the SRA01/04 cell apoptosis model. Inhibition of SIRT1 by siRNA knockdown increased ER stress activation, whereas SRT1720 treatment had opposite results. 4-PBA partly reverse the adverse effect of SIRT1 knockdown on apoptosis. In vivo, SRT1720 attenuated the lens opacification and weakened the ER stress activation in ARC rat models.
CONCLUSION: SIRT1 plays a protective role against TM-induced apoptosis in HLECs and slows the progression of cataract in rats by inhibiting ER stress. These findings suggest a novel strategy for cataract treatment focused on targeting ER stress, highlighting the therapeutic potential of SIRT1 modulation in ARC development.

AIM: To introduce a novel surgical technique using a Z-shaped incision without epithelial resection in ophthalmic pterygia.
METHODS: This was a prospective study. During pterygium surgery, all proliferative tissues were separated from the cornea and conjunctiva without resection of the tissues. The unaffected conjunctiva was incised in a Z-shape. The upper (or lower) conjunctival flap was sutured to the lower (or upper) normal conjunctiva on the limbal sclera, while the proliferative tissue was sutured to the upper conjunctiva (or lower) near the fornix.
RESULTS: Ten patients with pterygia were eligible for this study. Eight patients with primary pterygia and 2 with recurrent pterygia were included. The age of patients at surgery ranged from 47 to 90y (average: 71.9y). Five patients each showed right and left-sided pterygia. The postoperative follow-up periods were from 8 to 78mo (average: 25.0mo). The surgery was successfully conducted and wounds were favorably reconstructed in all patients. The proliferative tissues sutured to the normal conjunctiva showed palor and attenuated neovessles, and never showed re-growth after surgery. Nine patients did not show recerrence. Recerrent pterygium was noted in 1 patient, but additional treatments were not required.
CONCLUSION: The procedure involves the reconstruction of pterygial tissue and normal conjunctiva using a Z-shaped incision. The scleral limbal wound can be covered with non-affected conjunctiva without any excision of conjunctival epithelia in patients with primary or recurrent pterygia.

AIM: To evaluate refractive outcomes and corneal astigmatism changes after Toric implantable collamer lens with a central port (V4c T-ICL) implantation over 1y of follow-up.
METHODS: A retrospective study was performed including 50 eyes of 50 patients that underwent V4c T-ICL implantation. Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, refractive and corneal astigmatism changes and corneal coupling correction were evaluated preoperatively, 1 and 12mo postoperatively. Vector analysis was used for astigmatism changes. Coefficient of adjustment (CAdj) was calculated for corneal coupling analysis.
RESULTS: The mean UDVA achieved was 0.03 logMAR at 1mo and remained unchanged throughout the whole follow-up (P=0.193). At the last visit, 84% of the eyes achieved a CDVA of 0.00 logMAR or better. Regarding spherical equivalent refraction (SEQ), 96% of eyes were ranges of ±1.00 D and 84% of them within ±0.50 D. Also, 94% of eyes had a remaining refractive cylinder within ±1.00 D and 78% of them within ±0.50 D. Both, SEQ and refractive cylinder, remain stable over the postoperative follow-up (P=1.000 and P=0.660, respectively). In terms of surgically induced astigmatism (SIA), no statistically significant differences were found over the follow-up (P=0.102) and under correction was found with a correction index lower than the unit at each visit. A keratometric astigmatism induced of 0.59±0.53 (vector mean: 0.26×73º) D was reached at the last visit. No significant changes in terms of corneal astigmatism orientation were reported over post-surgery visits (P=0.129 and P=0.097 at 1 and 12mo respectively). No clinical significance was found for CAdj on with-the-rule astigmatism. No postoperative complications resulting from the surgery were found.
CONCLUSION: Refractive outcomes suggest that the V4c T-ICL implantation for correction of myopic astigmatism was satisfactory in terms of effectiveness, safety, and stability during 1y of follow-up. Corneal astigmatism induced by the incision around 0.5 D is achieved according to the remaining refractive cylinder found at one-year post-surgery. Corneal coupling analysis results in no unexpected spherical change.

“Hyper-grammaticality” of Norwid’s syntax (though not only)
Authors: Kozłowska Anna
Published: June 2024

The article discusses major characteristics of Norwid’s language and style in light of the concept of “hyper-grammaticality” [po-nad-gramatyczność] developed by the poet himself. Considered as a descriptive category, it organizes and foregrounds certain properties of his syntax as well as other elements. The adjective “hyper-grammatical” can be understood in three ways: 1. failing to comply with rules; 2. departing from linguistic convention; hence unconventional; 3. derived from a different level of language than grammar.Norwid’s works can be shown to display hyper-grammaticality in all of the above senses. Discussion of constructions that violate linguistic norms accounts for the following: anacoluthon,homonymic structures, obscurities related to functions of anaphoric elements, and disruptions of coherence. Unconventional elements departing from the epoch’s standards include, among other things, innovations in collocability, complications of syntax, numerous parenthetical remarks, and the usage of archaic constructions. In Norwid’s texts an important place is held not only by mechanisms proper to syntactical or grammatical level of enunciation, but also by phenomena present on other levels:meta-textualityandthematic-rhematic structure.
“Neither a leafnor a single toothin it.” Norwid beyond romanticism
Authors: Chlebowski Piotr
Published: June 2024

The article polemicizes with those findings in the history of literature that situate Norwid’s output within the Romantic movement, especially conclusions drawn by Zofia Stefanowska, Zofia Trojanowiczowaand Edward Kasperski, but also certain ideas developed by Rev. Antoni Dunajski, who argues that the poet’s historiosophic reflection is rooted in Hegelian dialectics (or German philosophy in general), seasoned with the Christian tradition and readings from the Bible. The authoremphasizes certain properties of Norwid’s poetics: an original concept of the protagonist, a personalist concept of history, irony, and the development of both the lyrical subject and the virtual lyrical audience, which all decidedly confirm that the poet functioned outside the said literary and ideological movement. These claims are also informed by the idea that even though Norwid operated beyond the Romantic convention, he would not embrace some other, existing trend (e.g. positivism or Parnassianism), or already represent one from the future (e.g. modernism). Instead, as a pre-modernist and precursor of contemporary lyricism, or a symbolist, he foreshadowed future literary movements. Accordingly, the article claims that Norwid’s work constitutes a separate and original phenomenon, at least in Polish literature.
Norwid in studies by Rolf Fieguth
Authors: Trybuś Krzysztof
Published: June 2024

This article aims discusses Rolf Fieguth’s studies of works by Norwid, focusing primarily on the German Slavist’s interpretations of the cycle Vade-mecum and the long poem Quidam. The first work reconstructed here, along with its assumptions and conclusions, is Fieguth’s 1985 study on “poetry in a critical phase”and the second is the 2005 essay on the comparative contexts of Norwid’s famous cycle (the latter was published in Polish in 2011). A lot of room is devoted in this section to Fieguth’s analysis of distortions introduced by Norwid at various levels of the poem’s organization. These remarks are complemented with an account of Fieguth’s comparatist conceptof “cultural confrontation,” which goes beyond dualistic accounts of literary creativity, revealing the invariably broad, European context of meetings between poets and texts, facilitated by the process of national cultures permeating each other. The second part of the article is devoted to Fieguth’s 2014 book Zaproszenie do „Quidama”. Portret poematu Cypriana Norwida [An invitation to Quidam. A portrait of Cyprian Norwid’s long poem]. Reflections on this publication concern not only its detailed findings about Norwid’s long poem but also the critic’s methodological assumptions, which have helped him to update the long-standing genre in the history of literature, namely the “author and his particular work” type of monograph. Among the issues addressed in the book, the article discusses, in particular, the difficulties accompanying interpretations of Quidamand the question of Norwid’s classicism. The third part of the article draws attention to Fieguth’s remarks onNorwid made in recent years (2017, 2018, 2020). The article thus summarizes Rolf Fieguth’s thirty years of research on the most important poetic achievements of the Polish poet.
La trayectoria de vida de Irma Carrica: una aproximación a los debates político-sanitarios de las décadas de 1960 y 1970 desde el método biográfico

Published: June 2024

Reconstruimos la trayectoria de vida de la enfermera y militante popular argentina Irma Carrica, entendida como una experiencia político-profesional ligada a sus redes de sociabilidad y atravesada por conflictos y contradicciones inherentes a su contexto histórico. Desde ese recorte analítico y teniendo en cuenta los recaudos sugeridos por el método biográfico de las ciencias sociales, nos adentramos en los debates político-sanitarios de las décadas de 1960 y 1970, principalmente en lo relativo a las disputas por el sentido de la “comunidad” en el campo de la salud. En particular, nos enfocamos en las contribuciones de un actor histórico colectivo –heterogéneo y plural, pero identificable en sus distintas modulaciones– que hemos denominado izquierda peronista en salud. Al analizar sus redes profesionales e intelectuales, hicimos hincapié en el rol que desempeñó Irma Carrica como referente de esa izquierda peronista en salud, a la hora de construir dinámicas alternativas para el abordaje comunitario en salud, que pusieron en tela de juicio los paradigmas epistemológicos y pedagógicos dominantes.

Published: June 2024

Soil nutrient cycling, the distribution of soil aggregates, and their stability are directly influenced by soil texture. Different sizes of soil aggregates provide microhabitats for microorganisms and therefore influence soil carbon (C) and nitrogen (N) mineralization. The purpose of the present study was to assess the aggregate stability and dynamics of carbon and nitrogen in macroaggregate size fractions (1-8 mm) with different clay content from meadow soils. Surface soil samples (0-15 cm) were collected from 4- to 5-year-old forage crops. Four macroaggregate size classes were isolated by dry sieving and analyzed for their mass proportions: fine macroaggregates (FM) (less than 1 mm), medium-fine macroaggregates (MFM) (1-2 mm), medium-coarse macroaggregates (MCM) (2-4 mm), and large-coarse macroaggregates (LCM) (4-8 mm). The dry mean weight diameter (MWD), organic carbon (OC), total nitrogen (TN), carbon and nitrogen of microbial biomass (C-MB, N-MB) were determined. CO2 emission and net nitrogen mineralized (NM) were measured after 14 weeks of incubation. The amounts of FM were significantly lower than those of intermediate macroaggregates (MCM and MFM) and decreased markedly with increasing clay content within soil macroaggregates. In general, the amounts of macroaggregate size fractions were lowest in soils with high clay content. MWD exhibited a significant correlation with particle size distribution, OC, and MB-C. OC, TN, MB-C, and MB-N contents within macroaggregates increased with decreasing macroaggregate size and increasing clay content of macroaggregate fractions. The CO2 emission and NM content increased with increasing macroaggregate size, indicating higher organic C and N mineralization activity in larger macroaggregates. Mineralization of OC was lowest in macroaggregate fractions with the highest clay content. We conclude that clay content can increase the protection of microbial biomass in meadow soils. Small macroaggregates tend to contain more recalcitrant organic matter compared to larger macroaggregates.

Authors: Hasan Tanveer , Bonny Moushumi Zaman , Das Rajesh Kumar , Sultana Salma , Islam Md. Touhidul , Sattar Abdus
Published: June 2024

The popularity of mobile gaming is increasing globally, fueled by technological advancements, high-quality smartphones with gaming features, and widespread internet access. A large number of young people and also children are mainly involved in different types of mobile gaming, primarily online mobile gaming, which is a matter of concern for society. This addiction leads to various psychological issues, including mental health problems, loneliness, introversion, insomnia, and a lack of self-control. Bangladesh’s lack of public mental health facilities exacerbates this challenge, particularly in rural areas. To address this issue, we have developed a machine learning model to predict the level of mental health issues faced by Bangladeshi urban children due to gaming addiction.  A total of 1996 data were collected from urban parents about their children's gaming activities and categorized them as 'Serious,' 'Partial,' and 'Normal.' The dataset was then split into a 70:30 ratio for training and testing purposes. K-Nearest Neighbors (KNN), Support Vector Machine (SVM), Multinomial Naïve Bayes, & Random Forest were applied as the machine learning approaches for prediction. Here, the Support Vector Machine gives good accuracy (92.75%), and other classifiers have different accuracy. The research highlights the significance of addressing gaming addiction in children and the potential of machine learning technology in predicting mental health issues, particularly in the absence of public mental health services. The study concludes by proposing the expansion of the research to include smartphone and mobile gaming addiction among Bangladeshi rural children and ensure a holistic approach to tackling the broader issue of technology-related addiction.

Published: June 2024

The development of civil construction technology in Indonesia is progressing along with the rise in high-rise building construction. The emergence of high-rise buildings has altered wind flow characteristics, leading to phenomena that can directly impact surrounding structures. One of the observable phenomena is the wind speed amplification caused by the narrowing of the wind flow section, known as the Venturi effect. This study aims to compare the outcomes of two Computational Fluid Dynamics (CFD) methods—Reynolds-Averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES)—against experimental results. The study employs a model of four buildings of similar height and symmetrical positioning, with a 72 mm passage width, to verify numerical simulations against experimental data. The RANS method yields a maximum wind speed amplification of 14.9% along the passage's centerline, which remains below the experimental prediction of 25.5% in Zone A. Conversely, the LES results show a higher wind speed amplification, reaching 40.2%, surpassing the experimental findings. Nevertheless, LES identifies a similar location for wind speed amplification observed in Zone A. Additionally, CFD simulations were conducted to analyze the effects of passage width, revealing that a passage width of 54 mm produces the highest wind speed amplification, with a ratio value of passage width to building influence scale (L/S) of 0.481. Further research on building model scale may be necessary to verify CFD accuracy compared to the actual scale. However, such simulations demand exceedingly high computational resources with current technology.

The first step in the road handling effort is to survey to get an accurate road condition value to take correct action in implementing maintenance. As pavement performance is known to be probabilistic, various levels of uncertainty must be assumed. Modern pavement management methods are ineffective without an effective model to predict pavement performance. Discrete-time Markov chains are the most widely used probabilistic models, and examples from different countries worldwide can be found in pavement management systems. This research aims to predict the value of road conditions during maintenance and compare road assessments with real conditions during road maintenance using the IRI, SDI, and PCI methods using the Markov process. The analysis method used is to collect secondary data from related departments and carry out direct data collection in the field to obtain condition values based on IRI, SDI, and PCI to forecast by making a pavement condition prediction model based on the Markov process and then assessing road conditions by comparing the three index values with the slightest deviation value. The analysis showed that the average value of road conditions with the IRI indicator is 4.45, which is moderate, and the most negligible difference between the probability distribution of pavement condition prediction modeling and the actual survey results was the IRI (International Roughness Index) method. This model is closest to the actual conditions during implementation, with a difference value of 5.7%.

This study aimed to investigate the effects of NPK fertilizer and coconut husk ash as an ameliorant on growth and photosynthetic levels of oil palm seedlings in peat soil growth media. A Completely Randomized Design (CRD) was used with two factors, NPK 12:12:17:2+TE including control, 30 g, 60 g, and 90 g per plant. Coconut husk ash includes control, 40 g, 80 g, and 120 g per plant. The data were statistically analyzed using ANOVA, and any observed significant difference led to Duncan's test at p<0.05. The combination of 90 g of fertilizer dose and 80 g of coconut husk ash produced the tallest plant height of 104.53 cm. The highest increase in stem girth was 6.01 cm. The photosynthetic rate was 39.11 μmol CO2 m-2 s-1, and the highest stomatal conductance was 0.21 H2O m-2 s-1. The highest internal CO2 and Water Use Efficiency was 177 μmol CO2 mol-1 and 16.15, respectively, while the best transpiration rate was 2.94 mM H2O m-2s-1. Additionally, the photosynthetic rate positively correlated with seedling height and stem diameter, with a R2 0.25 and 0.44 coefficient, respectively. Stomatal conductance was positively correlated with stem diameter, namely R2 0.04. Meanwhile, transpiration rate was negatively correlated with seedling height (R2 17%) and seedling stem diameter (R2 6.9%). Intracellular CO2 was negatively correlated with plant height but positively correlated with stem diameter. The results of this study are expected to be used in increased growth and photosynthesis.

Euglena sp. is rich in primary and secondary metabolite compounds. This cosmopolitan organism can survive extreme conditions such as salt stress because it can increase cell growth rate and metabolism. This mass cultivation research uses an open pond system that is very vulnerable to contamination, so variations in salinity of MgCl2 and CaCl2 are used as treatments because they minimize contamination. The research examines the correlation of salt types to cell growth rate, biomass, monosaccharide profile, paramylon, pigment, and lipid of Euglena sp. Research methods include preparation, medium making, mass cultivation, and measurement of test parameters. Data were analyzed through One-Way ANOVA followed by DMRT, with a 5% confidence level. Based on the research result, the highest value of biomass and paramylon content and productivity at CaCl2 treatment with consecutive values 0.013 ± 0.001, 0.002 ± 0.000, 9.556 ± 0.070, and 0.149 ± 0.019. Monosaccharides analysis produced in the form of sucrose, glucose, fructose, and arabinose amounted to < 10 ppm. CaCl2 treatment produced the highest sucrose of 6251 ppm. The highest chlorophyll-a and carotenoid pigments are located at CaCl2 treatment, respectively (1.698 ± 0.051)b and (0.500 ± 0.032)b. At the same time, the salt treatment has a significant effect on lipid content. To summarize, almost all metabolite compounds were highest in CaCl2 treatment. This research is expected to contribute to developing the Euglena sp. mass cultivation system as a source of bioenergy and biomaterials.

The amount of carbohydrates in sugarcane directly results from photosynthesis. This means that we can predict the weight of the cane, sucrose content, and sugar yield by examining the photosynthesis process. One way to measure the amount of photosynthesis is by using chlorophyll fluorescence or the OJIP test. This study aimed to determine the dominant OJIP variable that could predict cane weight, sucrose content, sugar yield, and measurement time. The study was conducted at the Asembagus Experimental Station in Situbondo Regency, East Java, Indonesia, from December 2016 to October 2017 using two-bud stem cuttings from 18 sugarcane clones and arranged them in a Randomized Block Design with three replications. Each clone in one replication was planted in five rows, each row being five meters long, and the center-to-center distance was 130 cm. OJIP variables were measured during the stalk elongation phase and the maturity phase. The results showed that sugarcane clones influenced OJIP variables other than Fv/Fm, cane weight, sucrose content, and sugar yield. The most accurate time for measuring OJIP variables was during the maturity phase. The dominant OJIP variables that could predict cane weight and sugar yield were TRo/RC, DIo/CS, ABS/RC, and PI (79.4% and 76.0%). The dominant predictors of yield were RC/CSo, RC/CSm, DIo/CS, PI, ABS/RC, and ETo/RC (92.9%). This study found that measuring OJIP variables during the maturity phase is ideal for predicting cane weight, sucrose content, and sugar yield. The OJIP test can quickly identify high-yielding sugarcane varieties.

Barong shrimp or lobster (Panulirus versicolor) is a fishery commodity with high economic value and great demand. This study aims to determine the genetic characteristics of Panulirus versicolor at the fishing location in the waters of Barrang Caddi Island, Makassar Strait, using primers LCO-1490F and HCO-2198R. Genomic DNA extraction was performed using a Quick-DNA Tissue Miniprep Kit for total isolation. For DNA purity, the elution buffer utilized in this research was specifically selected for its suitability for PCR amplification with KOD FX Neo, providing optimal conditions for efficient genetic analysis. The primary genes used were LCO-1490F with primers GGT CAA CAA ATC ATA AAG ATA TTG G, and HCO-2198R with TAA ACT TCA GGG TGA CCA AAA AAT CA. The study utilized a 1% agarose gel in a 1X TBE buffer at 50 voltage for 45 minutes to move the total DNA and PCR products. The analysis results at sampling stations 0.2-03 showed increasingly smaller genetic distances. Based on the results of BLASTn analysis, each station had the same type of Panulirus versicolor with a similarity of 99-100%. The morphological characteristics included a carapace with a black spot and black and white lines on each abdominal segment. The analysis of genetic variation in the lobster population on Barrang Caddi Island using primers LCO-1490F and HCO-2198R obtained a DNA fragment of 700 bp. The population of Panulirus versicolor lobster on Barrang Caddi Island showed a high level of similarity or low diversity.
Study of the System Response Analysis for the Eddy Current Test Crack Assessment on SS 316 Metal Arc Welding Joints

In modern industry, accurately assessing metal coupling by welding is critical. Given its reliability and other advantages, the eddy current test (ECT) is essential and commonly used in metal processing, especially welding. The classical ECT assesses the presence of discontinuities in the structure by monitoring the change in the probe's impedance. According to the wireless power transfer (WPT) theory, ECT members will exchange power wirelessly through mutual induction determined by inductance, capacitance, and resistance (LCR). The cracks will affect the mutual induction in the ECT's power exchange. Since LCRs are impedance components, the crack in the target will affect the system’s mutual induction, as it did to the impedance in the classical ECT. This study applies the WPT model of ECT, implements system response analysis to assess cracks, and compares the results with classical ECT. The test piece is a metal arc-welded joint on SS 316 with an implanted notch on the welded joint to simulate the crack. A series of initial tests were performed to ensure the test piece was defects-free. Simulation and a frequency scan were performed to acquire a safe measurement. The result was that both the classical ECT and the system’s response analysis successfully assessed the presence of cracks with excellent agreement. The system’s response analysis yields a more rapid result than classical ECT.

O objetivo deste artigo é o de apresentar uma outra abordagem para se trabalhar com dados em séries temporais em economia do que a já tradicional abordagem sob o domínio do tempo, ou seja, a utilização da abordagem sob o domínio da frequência. Essa abordagem espectral demonstra muitas vantagens que podem trazer importantes insights para os pesquisadores particularmente interessados em ciclos e relação de liderança entre as séries. Para atingir esse objetivo apresentamos as metodologias sob o domínio da frequência, com especial atenção na metodologia Wavelet, no qual conjuga, simultaneamente, análise sob o domínio do tempo e frequência. Realizamos simulações computacionais para aplicar e exemplificar a forma de entendimento dos resultados encontrados. No entanto, apesar do grande potencial, ainda são poucos os estudos empíricos em economia que utilizam essa abordagem. Esperamos com isso motivar novas pesquisas na área no campo da análise espectral.
The Sovereignty Category in the Practice of Russian Constitutional Justice
Authors:   Head of the Secretariat of the Constitutional Court of the Russian Federation, LL.D., Associate Professor, Taribo Evgeny V.
Published: June 2024

The category of “sovereignty” is inherent in the characteristics of the Russian state, this is predetermined by the provisions of the Constitution of the Russian Federation. The appeal to this category in the practice of constitutional justice is conditioned by the need to protect against increased threats to the rights and freedoms, security and well-being of society and the state itself. An analysis of the practice of the Constitutional Court of the Russian Federation shows that the category of “sovereignty” manifests itself and reveals itself in particular legal relations (international, federal, tax, customs, etc.) as a kind of protective mechanism that ensures the preservation of the state and legal system of Russia in conditions of the most acute and dangerous threats of both internal and external origin.
