Authors: Kurniawan Albertus Edy , Setiawan Andree Wijaya
Published: May 2024

Fruit flies (Bactrocera spp.) are pests that attack cayenne peppers, with attacks reaching 100%. Generally, farmers use synthetic insecticides, but in the long term this can disrupt the balance of the ecosystem and trigger pest outbreaks and resistance—integrated pest control by planting refugia as a micro-habitat for natural enemies. Marigolds and zinnias were chosen as refugia plants. The aim of the research was to determine the types of fruit flies that attack chili plants, the symptoms of fruit fly attacks on chili fruit, the effectiveness of marigold and zinnia plants in reducing the intensity of chili plant attacks, and external factors that influence the efficacy of refugia marigold and zinnia plants. The research was conducted in July – October 2023 in Jlarem Village, Gladaksari District, Boyolali Regency, using a Randomized Block Design (RAK) with four treatments, namely control, marigold, zinnia, and a combination of both, using six replications so that there were 24 experimental units with ten plants in each experimental unit. This research used a hygrometer thermometer (HTC2), camera, net, and binocular microscope. Observation variables include the type of fruit fly, attack symptoms, attack intensity, and external factors. The types of fruit flies found in the study area were Bactrocera dorsalis, Bactrocera umbrosa, and Bactrocera carambolae. Symptoms that arise due to fruit fly attacks on chili fruit are black spots on the skin of the fruit, which become more expansive over time, causing the fruit to rot and fall prematurely. Refugia planting effectively reduced the intensity of fruit fly attacks, with the lowest attack intensity in the combination treatment of marigold and zinnia at 22.16%. Several external factors influence the effectiveness of refugia in controlling fruit flies, namely environmental temperature and humidity and the types of plants growing around the cultivated land.

Cultivating vegetables using the hydroponic method is essential in developing Indonesia's agricultural sector. Vegetables are a type of food that is consumed at any time, so there is always a stable demand all the time. The ever-increasing demand and awareness of the importance of nutritious food make hydroponics an attractive option. The potential for high demand for vegetables opens up many business opportunities to meet people's needs, including cultivating hydroponic vegetables. This research aims to analyze the actual profits of hydroponic businesses and the maximum profits they can generate. The research location is in Deedad Hidroponik, Tamalate District, Makassar City, from July to October 2023. Primary data was collected through interviews and direct observation of owners and employees, and secondary data was obtained from previous studies related to this research. Linear programming analysis via the Simplex Method is used to analyze Deedad Hidroponik's profit maximization. Profit analysis involves production costs, inputs, production results, and business revenues. The research results show that Deedad Hidroponikis can generate profits of IDR 6,980,492 from various types of vegetables. Deedad Hidroponik's source of profit comes from the production of 4 kinds of vegetables: lettuce, bok choy, kale, and spinach. Through a linear programming approach, Deedad Hidroponikwill achieve maximum profits if they plant vegetables with a combination of 625 planting holes for lettuce, 302 planting holes for bok choy, 257 planting holes for kale, and 260 planting holes for spinach; therefore, they could increase profits to IDR 7,496,783 with the potential increase of 7.38%. This shows that selecting vegetable types and resource allocation can be optimized to achieve maximum profits.

Published: May 2024

The textile industry plays an important role in the global economy; however, it faces persistent challenges related to reducing rework for improving productivity. The purpose of this study is to summarize some scientific researches about production delay caused by rework in a clothing and accessory industry. It provides a general overview of the current state of knowledge concerning the interdependence between reduced productivity and rework rate. The research process is based on the Functional Analysis System Technique. It facilitates a systematic examination of sequential and logical steps necessary to achieve objective and attain outcomes. Functional Analysis System Techniques not only provides a structured methodology but also aids in identifying the successive functions crucial for attaining desired outcomes. The initial phase involves conducting a comprehensive systematic literature review focused on productivity issues stemming from rework within the textile industry. The first phase, related to the Seiri of the 5S methodology, involves conducting a comprehensive systematic literature review focused on productivity issues stemming from rework within the textile industry. Subsequently, the filling of a literature review synthesis matrix using Excel is conducted which represents Seiton. Next, focusing specifically on the Lean tools employed utilized and the corresponding productivity improvements, data are extracted. This corresponds to Seiso step. Following this, a Network Meta-Analysis is applied, representing the Seiketsu. Finally, the identification of the most effective Lean tools combination to reduce rework is undertaken, corresponding to Shitsuke. As results, the Ishikawa Diagram appears to have obtained the best ranking position according to the rankogram. Ishikawa Diagram is often associated with other tools to multiply its performance. The study's findings highlight that the Ishikawa, Pareto, Single-Minute Exchange of Die and Work Study combination emerges as the most effective approach for minimizing rework and enhancing productivity, as indicated by the League Table. This network meta-analysis provides a comprehensive overview of the Lean tools synergy effectiveness in rework reduction and productivity improvement strategies in textile industries. While powerful, Network Meta-Analysis has limitations including reliance on indirect comparisons from studies that may not directly compare all treatments, inheriting biases and complexities, which can pose challenges in assessing result certainty.
Resource Optimization in H-CRN with Supervised Learning Based Spectrum Prediction Technique
Authors: Prabhavathi S. , Saminadan V.
Published: May 2024

Cognitive radio network shows potential means of granting intensifying demand for wireless applications. In this model, an efficient resource optimization scheme with Priority Pricing Technique (PPT) is proposed with supervised learning-based SVM to tackle limited spectrum availability and underutilization in Hybrid-Cognitive Radio Networks (H-CRN). H-CRN works under the principle of detection of PUs states (active/inactive). If spectrum sensing is made in favor of active PUs, then the CSI (Channel State Information) is estimated and works in underlay principle. If it is made in favor of inactive PUs, then the transmission is performed in overlay manner. In the proposed PPT the PUs and SUs with highest channel gain have the highest priority to use the spectral resources. SVM is used as an effective technique of spectrum sensing to provide higher probability of detection of PUs as soon as possible. The proposed method faces following challenges such as in order to enhance the CRN transmission performance, the PUs have to withstand more interference power and transmit power control is needed in improving the sum rates when the interference is severe in H-CRN. With Simulation outcomes, the assessment of the proposed (PPT) model among (Fixed Pricing Technique and Without Pricing Technique) indicates the proposed method's improved efficiency. The results reveal significant effectiveness in obtaining better classification accuracy with less computation complexity, increased throughput, spectral efficiency and energy efficiency of the network.

Published: May 2024

The production demands highly specific environmentally and toxicologically acceptable plant protection products are increasing. Computer-aided molecular design of new active components has a great deal in developing plant protection products to avoid that long-lasting and expensive process. Computational design of future compounds and their synthesis, evaluation of their effectiveness on harmful and beneficial organisms in the soil, as well as detailed research mechanism of action at the molecular level, represents an initial stage in the long-lasting and expensive process of plant protection products. In this paper, the recent advances in quantitative structure-activity relationship (QSAR) studies, molecular docking, and calculation of “Pesticidelikeness properties “, as well, have been reviewed. QSAR models for antifungal activities against phytopathological fungi were obtained for the thiazoline and coumarine derivatives, coumarinyl Schiff bases, and coumarin-1,2,4-triazoles. A molecular docking study revealed that antifungal activities of fluorinated pyrazole aldehydes are related to the inhibition of proteinase K, coumarinyl Schiff bases with endoglucanase and pectinase, hybrids of coumarins and 1,2,4-triazoles with sterol 14α-demethylase inhibition, 3-gydroxycoumarin chitin synthase, while γ-thionins strongly binds to fungal membrane moieties.

Visual word identification beyond common words: The role of font and letter case in brand names
Authors: Labusch Melanie , Duñabeitia Jon Andoni , Perea Manuel
Published: May 2024

While abstractionist theories of visual word recognition propose that perceptual elements like font and letter case are filtered out during lexical access, instance-based theories allow for the possibility that these surface details influence this process. To disentangle these accounts, we focused on brand names embedded in logotypes. The consistent visual presentation of brand names may render them much more susceptible to perceptual factors than common words. In the present study, we compared original and modified brand logos, varying in font or letter case. In Experiment 1, participants decided whether the stimuli corresponded to existing brand names or not, regardless of graphical information. In Experiment 2, participants had to categorize existing brand names semantically – whether they corresponded to a brand in the transportation sector or not. Both experiments showed longer response times for the modified brand names, regardless of font or letter-case changes. These findings challenge the notion that only abstract units drive visual word recognition. Instead, they favor those models that assume that, under some circumstances, the traces in lexical memory may contain surface perceptual information.

Descolonización de la educación peruana: una mirada epistemológica hacia la formación del profesorado
Authors: Oyola Gaspar Emperatriz Karina , Durand Cuba Krisel Anayka , Gutiérrez Huamaní Oscar
Published: May 2024

En Latinoamérica, los conocimientos y planteamientos epistemológicos son de afuera, de un grupo de poder hegemónico. Descolonizar la educación requiere de una insurgencia ante el conocimiento e ideología eurocentrista, considerando aspectos propios de la cosmovisión andina y la cultura ancestral; reescribir y reconstruir nuestras bases epistemológicas hacia la formación de profesores, para obtener resultados positivos de contenido y de forma educativa. La descolonización permite alcanzar una sociedad con menos brechas de desigualdad. En la educación peruana y la de otros países latinoamericanos se evidencia la influencia del occidentalismo dominante, que no permite el despegue de epistemologías que fortalezcan la educación. Es importante respetar la pluralidad de las epistemologías del sur y la complejidad educativa. La reconstrucción de la epistemología andina es un camino hacia la descolonización de la educación peruana.

Bruxism is a parafunctional behavior that involves clenching and grinding of the teeth, as well as increased masseters activity with or without contact with the teeth. It can happen during the day or at night. Diagnostic tools for bruxism include self-assessment questionnaires, clinical evaluation forms and polysomnography. Stress and anxiety represent two psychological factors that have been frequently related to bruxism. Twenty students in dental medicine were included in this study and a self-assessment questionnaire together with a clinical evaluation form were used as diagnostic tools for bruxism. Consequently, two groups developed: group A or non-bruxers and group B or bruxers. A questionnaire of perceived stress and anxiety levels was applied for both groups. The average score for group A was 20.8 and for group B was 31.8 with a statistically significant difference (p=0.0062, T-test). Higher perceived stress level was associated with a higher risk of bruxism, along with higher anxiety level, parafunctions, and poor sleep quality. In order to accurately diagnose bruxism, a comprehensive clinical examination and, if feasible, a polysomnography ought to be performed after completing a self-assessment questionnaire.

Methods: This randomized case-control study was conducted at Watim General Hospital over four months from April to July 2023. A total of 120 children aged 3 months to 12 years with acute diarrhoea were included and randomly allocated to two groups. Group A (n=60) received standard treatment with oral rehydration therapy, while Group B (n=60) received oral rehydration therapy, zinc, probiotics, and racecadotril. The primary outcome measured was the mean duration of illness, and the secondary outcome was the number of stools 48 hours after the start of treatment. Data were collected using a pre-designed proforma and analyzed using SPSS version 24.
Results: The study population had an average age of 50.35±41.52 months, with equal gender distribution. The mean duration of illness in Group A was 2.72±1.34 days, while in Group B, it was 2.70±1.29 days. There was no statistically significant difference in the mean duration of illness between the two groups (p=0.945).
Conclusion: This study did not demonstrate a significant reduction in the mean duration of illness for children with acute gastroenteritis using standard treatment with or without racecadotril. Further investigations and large-scale studies may be needed to establish the efficacy of racecadotril in the management of acute diarrhoea in children.

Published: May 2024

Objective: The objective of the article is to assess anxiety in patients undergoing complete denture treatment.
Method: A valid pre-structured questionnaire was presented to the patients desirous of receiving complete dentures after obtaining informed consent. The questionnaire for the survey was filled out and collected from 500 patients receiving complete denture treatment.
Results: Of the 500 patients, 61.1% had prior denture experience, and 38.1% were undergoing denture placement for the first time. While 84.4% felt comfortable with the idea of complete dentures, 15.4% found it repulsive. Reasons inducing anxiety in a dental setting, include materials (28.3%), instruments (8.2%), the dentist's chair (28%), and other reasons (60.5%). Specific concerns related to complete denture use included fear of breakage (16.6%), ill-fitting prosthesis (43.3%), and discomfort with wearing and removing dentures (25%). Patients overwhelmingly appreciated having the entire procedure described beforehand (99.2%) and considered language understanding by the doctor as crucial for good treatment (97.8%).
Conclusion: There is a greater need for the patient's expectations to be understood and their doubts, concerns and fears to be narrowed by effective communication. A good understanding of patients' mental attitudes will help us improve the technique of dentists towards complete denture treatment in a more patient-friendly way.
Keywords: Anxiety, attitude, communication, complete dentures.

Objective: To establish a relationship between maternal weight gain during pregnancy and a newborn’s birth weight.
Method: A total of 120 patients were selected for this study. The weight and height of all patients were recorded in the first month of pregnancy and at term. Weight gain during pregnancy was placed in three categories. Category 1,2 and 3 included patients with weight gain of 4.9 kg or less, weight gain between 5 to 10 Kg and weight gain over 10 kg respectively. The weight of all newborns was also recorded. The association of maternal weight gain with neonate's birth weight was looked for.
Results: In our study, 4.16% of women were underweight, 49.17% of women were labelled normal weight, 45% were overweight and 2% were obese. Five per cent of women gained less than 5 kg weight during pregnancy, the majority (88.33%) gained between 5 to 10 kg and only 8% gained weight more than 10 kg. In our study, 9.17% of newborns were born with low birth weight, 90.83% had normal birth weight and no newborn fell into the category of macrosomia. Mean birth weight was 2.52±0.26 kg in mothers who gained less than 5 kg weight during pregnancy. Similarly, the mean birth weight was 2.92±0.23 in mothers who gained weight between 5 to 10 kg. Mean birth weight was 3.34±0.23 in mothers who gained weight more than 10 kg.
Conclusion: It is concluded in our study that maternal weight gain during pregnancy is strongly associated with the birth weight of the newborn.

Objective: To find out the toxic effects of arsenic on the histology of the vagina and reproductive hormones of female Sprague Dawley rats.
Methods: 60 female Sprague Dawley rats were divided into control group A and experimental group B with 30 rats in each group. The gross weight of all the rats was checked before and at the end of the experiment. After one week of acclimatization, the control group was administered 10ml of distilled water by oral gavage daily for 14 days and the experimental group was administered 4µg of sodium arsenite dissolved in 10ml of distilled water by oral gavage daily for 14 days. After being euthanized by chloroform inhalation on day 15, blood from each rat was drawn by a single intra-cardiac puncture and stored for biochemical analysis. After that, rats were sacrificed and the whole reproductive tract was removed and vaginal sections were prepared and stained with hematoxylin and eosin (H&E ). The histological parameters were analyzed by using Image J software. Whereas, biochemical parameters e.g. serum LH and FSH levels were analyzed by ELISA. 
Results: After exposure to a low dose of arsenic administered for a short period, the gross weight of rats, weight of reproductive tract, height of vaginal epithelium and serum FSH and LH values were significantly reduced in experimental animals as compared to control animals with p-value < 0.05.
Conclusion: Low dose of arsenic given via contaminated drinking water for a short period is very toxic to the female reproductive tract which is evident by the histological changes in the vagina and deranged hormonal profile of female Sprague Dawley rats.

The Square Kilometre Array (SKA) radio telescope will achieve unparalleled sensitivity and angular resolution, substantially progressing our research into the formation and development of the early universe. Sensitivity is one of the most critical telescope metrics, often used to determine the observing mode and observing time of a radio source. It is also used to determine imaging parameters to balance imaging sensitivity and spatial resolution during data processing. In this paper, to meet the needs of continuum imaging pipeline data processing for the SKA1-LOW telescope, we derive equations for point-source-sensitivity (PSS) calculations under multichannel, multipolarization, discrete frequency sampling, discrete time sampling, and different weighting schemes. After validating the correctness of the equation, we improved and refined the sensitivity calculation application in the Radio Astronomy Simulation, Calibration, and Imaging Library, and further calculated the variation of the PSS versus angular resolution for the full-scale SKA1-LOW with different weighting schemes, and provided SKA1-LOW broadband image performance as functions of angular scale for four frequencies. These results can provide not only a theoretical basis for the construction and commissioning of the SKA1-LOW telescope but also guidance for imaging processing in future scientific data processing.

We have analyzed Chandra and Suzaku observations of the globular cluster Terzan 6, made when the recurrent transient GRS 1747–312 was in quiescence. Our analysis reveals the presence of a second eclipsing, bursting neutron star low-mass X-ray binary in the central regions of the cluster, in addition to GRS 1747–312. The new source, which we name Terzan 6 X2, is located only ∼0.″7 away from GRS 1747–312 in the 2021 Chandra images. The detection of a 5.14 ks long eclipse in the light curve of X2 at a time not predicted by the ephemeris of GRS 1747–312 confirms that it is an unrelated source. Using the Suzaku light curve from 2009, which, in addition to a type I X-ray burst, also showed an eclipse-like feature, we constrain the orbital period to be longer than 16.27 hr. The 0.5–10 keV luminosities of X2 vary in the range of ∼0.24–5.9 × 1034 erg s−1 on timescales of months to years. We have identified a plausible optical counterpart of X2 in Hubble Space Telescope F606W and F814W images. This star varied by 2.7 mag in V
606 between epochs separated by years. In the cluster color–magnitude diagram, the variable counterpart lies in the blue-straggler region when it was optically bright, about 1.1–1.7 mag above the main-sequence turn-off. From the orbital period–density relation of Roche-lobe filling stars, we find the mass-donor radius to be ≳0.8 R

Bayesian Survey of the Dense Matter Equation of State Built upon Skyrme Effective Interactions
Authors: Beznogov Mikhail V. , Raduta Adriana R.
Published: May 2024

The nonrelativistic model of nuclear matter (NM) with zero-range Skyrme interactions is employed within a Bayesian approach in order to study the behavior of the neutron star (NS) equation of state (EOS). A minimal number of constraints from nuclear physics and ab initio calculations of pure neutron matter (PNM) are imposed together with causality and a lower limit on the maximum mass of an NS to all our models. Our key result is that accounting for correlations among the values that the energy per neutron in PNM takes at various densities and that are typically disregarded efficiently constrains the behavior of the EOS at high densities. A series of global NS properties, e.g., maximum mass, central density of the maximum mass configuration, minimum NS mass that allows for direct URCA, and radii of intermediate and massive NSs, appear to be correlated with the value of effective neutron mass in PNM at 0.16 fm−3. Together with similar studies in the literature our work contributes to a better understanding of the NS EOS as well as its link with the properties of dense NM.

The repointing time of the X-Ray Telescope (XRT) instrument on the Neil Gehrels Swift Observatory satellite has posed challenges in observing and studying the early X-ray emissions within ≈40 s after a gamma-ray burst (GRB) trigger. To address this issue, we adopt a novel approach that capitalizes on the cosmological time dilation in GRBs with redshifts ranging from 3 to 9. Applying this strategy to Swift/XRT data, we investigate the earliest X-ray emissions of 368 GRBs from the Swift catalog, including short and long GRBs. We compare the observed time delay between the GRB trigger and the initial Swift/XRT observation, measured in the GRB observer frame, and the corresponding cosmological rest-frame time delay (RTD). This technique is here used in the analysis of GRB 090423 at z = 8.233 (RTD ∼8.2 s), GRB 090429B at z ≈ 9.4 (RTD ∼10.1 s), and GRB 220101A at z = 4.61 (RTD ∼14.4 s). The cosmological time dilation enables us to observe the very early X-ray afterglow emission in these three GRBs. We thus validate the observation of the collapse of the carbon–oxygen core and the coeval newborn neutron star (νNS) formation triggering the GRB event in the binary-driven hypernova (BdHN) scenario. We also evidence the νNS spin-up due to supernova ejecta fallback and its subsequent slowing down due to the X-ray/optical/radio synchrotron afterglow emission. A brief gravitational-wave signal may separate the two stages owing to a fast-spinning νNS triaxial-to-axisymmetric transition. We also analyze the long GRB redshift distribution for the different BdHN types and infer that BdHNe II and III may originate the NS binary progenitors of short GRBs.

We report the discovery of the 10 kpc scale radio lobes in the Sombrero galaxy (NGC 4594), using data from the Continuum Halos in Nearby Galaxies—an Expanded Very Large Array Survey project. We further examine the balance between the magnetic pressure inside the lobes and the thermal pressure of the ambient hot gas. At the radii r of ∼(1–10) kpc, the magnetic pressure inside the lobes and the thermal pressure of the ambient hot gas are generally in balance. This implies that the jets could expand into the surroundings to at least r ∼ 10 kpc. The feedback from the active galactic nucleus jet responsible for the large-scale lobes may help to explain the unusually high X-ray luminosity of this massive quiescent isolated disk galaxy, although more theoretical work is needed to further examine this possibility.
