Puhjajar is one of the villages in Papar District, Kediri Regency with the majority of the population making their living as producers of realizeyah crackers. They are members of associations, each of which consists of 11 craftsmen, where each craftsman has four to six members. The realizeyah crackers produced by the people of Puhjajar village are very famous among the cracker industry, especially in Kediri. In fact, in the marketing of these realizeyah crackers, they are sent outside Java and overseas. However, the problem arises as the market for realizeyah cracker products increases, namely that the realizeyah cracker producers have not been able to increase their production capacity. So there are often delays in delivery which can result in disappointing consumers. This happens because the production process is quite long, and raw materials are sometimes difficult to obtain. It was from this problem that the Nusantara University PGRI Kediri community service team tried to help solve the problems faced by producers by designing an automatic cracker cracker chopping machine. The results obtained after using this machine were an increase in production capacity, which initially only reached 80kg/day to around 350kg/day. Manufacturers are of course greatly helped by the existence of this chopping machine, they are ultimately able to meet the quite high market demand.

Mechanism of Opal-CT deposit from the Lam Narai Volcanics in Lop Buri, Thailand by using Petrography
Authors: Pimwaree Thitiwatthanakarn  , Supanut Suntikoon
Published: March 2024

Common opals were discovered in the rhyolite host rock, where various structural features such as cavities, fractures, and veins are observed. These voids served as pathways for the infiltration of silica-rich fluids originating from meteoric water, establishing a hydrothermal connection. The aqueous solution derived from meteoric water actively dissolves silica from the rhyolite host rock, thereby increasing the silica saturation within the fluid. Subsequently, the silica-saturated hydrothermal fluid fills the cavities and veins within the host rock. The margin of the host rock underwent alteration as it interacted with infiltrating hydrothermal fluid in a phenomenon known as hydrothermal fluid-rock interaction. At the periphery of the cavities, quartz crystals begin to form, effectively reducing the concentration of dissolved silica in the solution. As a result, the subsequent precipitation of amorphous opals occurs, predominantly within the inner part or central region of the vein or cavity. The formation of opals associated with Lam Narai volcanic activity occurred at a relatively high temperature of about 105-170 °C through a hydrothermal process.

Authors: C. Kayelvizhi  , A. Emimal Kanaga Pushpam
Published: March 2024

The main objective of this work is to propose the polynomial based Subdomain collocation method using successive integration technique for solving delay differential equations (DDEs). In this study, the most widely used classical orthogonal polynomials, namely, the Bernoulli polynomial, the Chebyshev polynomial, the Hermite polynomial, and the Fibonacci polynomial are considered. Numerical examples of linear and nonlinear DDEs have been considered to demonstrate the efficiency and accuracy of the method. Approximate solutions obtained by the proposed method are well comparable with exact solutions. From the results it is observed that the accuracy of the numerical solutions by the proposed method increases as N (order of the polynomial) increases. The proposed method is very effective, simple, and suitable for solving the linear and nonlinear DDEs in real-world problems.

Differential mode of processing GNSS in the preferred choice for high precision assignments in areas where there are active reference stations. Studies into the performance of these continuously operating reference stations (CORS) have mainly been centered on either session times or baseline lengths. Active CORS have emerged replacing the old passive stations. However, these innovations in the science of spatial data acquisition needs to be monitored for networks strength and sensitivity. In this study, GPS data from five CORS stations for 12 days were used and processed with RTKLib. The research was restricted to baseline lengths of 2.5 to 13.5 km with varying session lengths starting from 1 hour to 24 hours. 3D error for each baseline and 3D RMS for each group of baselines were subsequently computed. A plot of the results was analyzed and compared. This comparison reveals that Geodetic accuracy (below 1cm) is achieved after 4 hours of observation session showing that the precision of Rtklib baseline solution can reach sub-centimeter level and therefore can yield reliable results in almost any professional project.

Coliform-like bacteria can be found when examining coliforms in fresh water using the CCA media on membrane filter method. Therefore, it is necessary to characterize and identify coliform-like colonies that grow on CCA medium so that is easier to perform colony count analysis. One hundred ml of fresh water samples were filtered using filter membrane paper and then planted in CCA medium. Two different colonies growing on the media (red (A) and pink-purple (B)) were subjected to oxidase test, gram staining and re-cultured in various growth media such as blood agar, nutrient agar, MacConkey, and B. coli agar. Both colony types were also identified with Vitek MS to determine the species. The results of the examination showed that the red colonies (code A) were coliform-like bacteria, while the pink-purple colonies (code B) were coliform bacteria. The characteristics of coliform-like bacteria are that they produce hemolysis on blood agar and do not ferment lactose. Identification with Vitek MS showed that the isolated coliform-like bacteria was Aeromonas hydrophilla. Therefore, it can be concluded that Aeromonas sp. are coliform-like bacteria that grow on CCA, so further verification is needed when counting membrane filter colonies using CCA media.

Disturbances in gut microbiota are prevalent in inflammatory bowel disease (IBD), which includes ulcerative colitis (UC). However, whether these disturbances contribute to development of the disease or are a result of the disease is unclear. In pairs of human twins discordant for IBD, the healthy twin has a higher risk of developing IBD and a gut microbiota that is more similar to that of IBD patients as compared with healthy individuals. Furthermore, appropriate medical treatment may mitigate these disturbances. To study the correlation between microbiota and IBD, we transferred stool samples from a discordant human twin pair: one twin being healthy and the other receiving treatment for UC. The stool samples were transferred from the disease-discordant twins to germ-free pregnant dams. Colitis was induced in the offspring using dextran sodium sulfate. As compared with offspring born to mice dams inoculated with stool from the healthy cotwin, offspring born to dams inoculated with stool from the UC-afflicted twin had a lower disease activity index, less gut inflammation, and a microbiota characterized by higher α diversity and a more antiinflammatory profile that included the presence and higher abundance of antiinflammatory species such as Akkermansia spp., Bacteroides spp., and Parabacteroides spp. These findings suggest that the microbiota from the healthy twin may have had greater inflammatory properties than did that of the twin undergoing UC treatment.

Published: March 2024

Preweaning mortality is a widespread problem in laboratory mouse breeding, particularly in the case of fragile mouse models. While numerous studies explore alternative care methods to increase the survivability of common mouse strains, there remains a paucity of research into the care of mice with fragile health conditions that result from induced or natural genetic mutations. In this study, standard husbandry practices were enhanced by the addition of a softened diet, a nutritionally fortified dietary supplement, soft bedding, gentle handling techniques, decreased handling, lengthened weaning age, and dam productivity tracking. This alternative care plan was shown to increase the survival of a fragile recessive dystrophic epidermolysis bullosa mouse model, and some aspects could be used in developing a care plan for other fragile mouse strains.

Esta falla se asoció con un puntaje Injury Severity Score (ISS) mayor o igual a 20 (RR=6,4; IC95% 2,34-17,86), presencia de hemoperitoneo en la tomografía axial de ingreso (p=0,02) y el grado de lesión esplénica (p<0,001). Las complicaciones ocurrieron en el 31,7 % y las infecciones fueron la causa más frecuente en ambos grupos. La mortalidad global fue 7,3 % (3 pacientes en el grupo de manejo no operatorio y 3 en el de manejo operatorio), debida a las lesiones asociadas en la mayoría de los pacientes. Conclusiones. La mayoría de pacientes con trauma cerrado de bazo puede recibir manejo no operatorio, siendo este un método seguro y efectivo para la preservación esplénica, si se mantiene una vigilancia clínica continua, especialmente en casos de trauma grave.
The Hebrew Bible and Philosophy of Religion
Authors: Gericke Jaco
Published: March 2024

The complex relations between Hebrew Bible interpretation and the discipline of the Philosophy of Religion were last discussed in detail a decade ago (Gericke 2012). In the years that followed, the associated literature was seen as samples of a recent return to philosophy of religion as auxiliary discourse, albeit one that had yet to obtain a clear research profile (Schmid 2019). Shortly thereafter, evidence of a variety of philosophical approaches to the HB/OT as a distinct emergent current was provided (Keefer 2022). The original contribution of this article and its objective is to supplement and compliment the related research by way of an update on the relations between the Bible and Philosophy with special attention to Philosophy of Religion.

The article examines the publicistic texts of the journal «Suchasnist», which at various times of its existence developed the national idea, united Ukrainians, supported the patriotic spirit, oriented politically, informed about the events of cultural life, published new works of art by domestic writers, revealed to readers the names of those banned during the Soviet era talented representatives of the Ukrainian diaspora. The main problems of the journal in the last years of its operation have been clarified. The issue of the negative impact of the entire Russian and Soviet heritage on the development of Ukraine, the unreliability of many historical facts and their manipulation, the peculiarities of Ukrainian democracy, the strengthening of the influence of the oligarchy, the inertia of civil society, and the decline of national culture is considered. The place of keywords in the context of journal publications, which are characterized by frequency of use and additional associative subtext, is determined. Key words: Ukraine, independence, civil society, nationalism, Ukrainian elite, power, revolution.

Published: March 2024

Russia’s full-scale invasion of Ukraine has changed the media landscape not only in Ukraine but also around the world. The established standards that journalists have been using in their work for a long time need to be revised and adapted to the new conditions. The article analyzes the challenges that Ukrainian journalists have to overcome in the context of the Russian-Ukrainian war. A comparative analysis of standards and rules for covering events in peacetime and wartime is presented. The essence of the new terms for standards that have been used in Ukraine during the full-scale war is revealed. The author emphasizes the ability of Ukrainian journalists to adhere to ethics and morality, to experience and comprehend the new reality, and to form new rules of journalistic creativity. Different opinions and positions of journalists who cover military events in Ukraine on a daily basis are collected. The article analyzes the experience of Ukrainian and foreign journalists in acting, understanding and forming content within the standards of journalistic creativity, and the development of new rules by the journalistic community and state institutions, taking into account the challenges faced by Ukrainian journalism during the Russian-Ukrainian war. The author theoretically substantiates the standards and their features; highlights the basic principles of preparation of materials taking into account traditional standards; substantiates the need to improve the rules, expand their understanding and formulation, taking into account the latest challenges. Key words: standards of journalistic creativity; media ethics; military journalism, balance of opinion, reliability of sources, media analytics, commentary, efficiency, accuracy.

Background: The objective was to estimate the effect of intrapartum amnioinfusion (AI) for recurrent variable decelerations on neonatal morbidity. The primary outcome was composite neonatal neurologic morbidity assembled from individual neonatal outcomes used clinically with suspected hypoxic-ischemic encephalopathy (HIE). Secondary outcomes were composite neonatal morbidity not associated with HIE. Methods: Data Sources: A predefined, systematic search was conducted through Ovid Medline, Embase, CINAHL PLUS, Cochrane library (including CENTRAL), Scopus, and Clinicaltrials.gov and was used to identify studies assessing the relationship between intrapartum AI and neonatal morbidity yielding 345 unique citations from 1982 to 2018. Study Eligibility Criteria: Randomized control trials that compared intrapartum AI to no AI for recurrent variable decelerations and included neonatal outcomes were included. Randomized trials comparing AI for other indications (e.g., meconium aspiration syndrome) were excluded, as were studies on intrapartum AI that lacked a control group (i.e., no amnioinfusion). Results: A total of 3 randomized control trials met the selection criteria. Outcomes from 282 neonates exposed to intrapartum AI for recurrent variable decelerations were compared to those from 286 who had fetal monitoring with recurrent variable decelerations but did not receive AI. There were no data on neonatal neurologic morbidity outcomes related to HIE. Among the data available, composite neonatal morbidity was not significantly different with AI (28.7% vs. 59.1%, pooled risk ratio, –0.30; 95% CI (95% confidence interval) –0.99–0.40; I2 = 94.51%; p = 0.40). Separated by individual outcomes contributing to the composite, intensive care unit admissions (ICU) (1 study; 6.8% vs. 16.5%; risk ratio 0.45; 95% CI 0.25–0.83) were less likely in those receiving an intrapartum AI, compared to no intrapartum AI while there was no difference in umbilical cord pH <7.20 (1 study; 19% vs. 8%; p = 0.62). There was no difference in Apgar scores <7 at 1 and 5 minutes on pooled analysis. Conclusions: Few studies have been published on the effect of intrapartum AI for recurrent variable decelerations on neonatal morbidity. Nevertheless, this meta-analysis suggests that intrapartum AI for recurrent variable decelerations may improve surrogate markers of neonatal morbidity, but further research is warranted.

Published: March 2024

Background: Vulvovaginal candidiasis (VVC) is a prevalent infectious disease that affects the majority of women. While Candida albicans is the most common cause of VVC, the prevalence of non-albicans species is increasing, and mixed infections have made treatment more challenging. This study aimed to identify Candida species and detect mixed infections in women with VVC in a tropical region of northeastern Iran, employing the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Methods: In the prospective study, a total of 270 specimens of vaginal discharge were collected using sterile swabs from patients suspected of having VVC. After extracting DNA from Candida colonies, the genome was amplified using PCR with specific primers. Species identification was conducted through PCR-RFLP analysis of the ribosomal DNA internal transcribed spacer (ITS) regions, using the MspI restriction enzyme. Results: Out of the 270 specimens suspected of VVC, 167 tested positive for Candida cultures. Among these positive Candida cultures, Candida species were identified in 150 specimens, with 44 (29.3%) showing evidence of mixed Candida infections. The species of Candida in 17 specimens were not identified. Out of the 190 identified Candida isolates included, the distribution was as follows: 85 (44.8%) C. albicans, 39 (20.5%) C. glabrata, 28 (14.7%) C. guilliermondii, 11 (5.8%) C. kefyr, 11 (5.8%) C. parapsilosis, 8 (4.2%) C. tropicalis, and 8 (4.2%) C. krusei. The mixed Candida species combinations observed were as follows: C. albicans/C. guilliermondii 26 (65%), C. albicans/C. kefyr 4 (10%), C. parapsilosis/C. glabrata 4 (10%), C. parapsilosis/C. tropicalis 4 (10%), C. krusei/C. tropicalis 2 (5%), C. albicans/C. parapsilosis 1 (2.5%), C. albicans/C. krusei 1 (2.5%), C. glabrata/C. guilliermondii 1 (2.5%), and C. kefyr/C. tropicalis 1 (2.5%). Conclusions: In women with VVC in the tropical region of northeastern Iran, the prevalence of clinical non-albicans species is higher than that of C. albicans. Furthermore, there is a notable high prevalence of clinical specimens containing mixed Candida infections.

Background: Attention to mothers during pregnancy, childbirth, and postpartum has focused on the physical aspects, overlooking mental health, which is critical to maternal well-being and childbirth. The aim of this study was to analyze the levels of anxiety experienced during labor and within the first 24 hours post-delivery, in order to identify the associated social and clinical factors associated with such anxiety. Methods: We performed a prospective observational follow-up study involving 448 women. Validated state and trait anxiety questionnaires, namely State-Trait Anxiety Inventory (STAI), which were employed in the study participants. All tests were performed with a bilateral approach. The p-values < 0.05 were considered significant. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS, v.22.0, IBM Corp, Chicago, IL, USA). Results: State anxiety was more frequent among primiparous pregnant women, individuals who did not attend maternal education classes, and those with a history of prior abortion or cesarean section. Additionally, a significant association was observed with a history of mental disorder. Concerning Trait anxiety, significantly higher levels of anxiety were found in women with lower levels of education and in patients with a history of mental health issues. At 24 hours postpartum, elevated anxiety was more frequent in primiparous and significantly more frequent in patients with difficult deliveries, women whose infants were admitted to the Neonatal Intensive Care Unit (NICU), those lacking skin-to-skin contact, and those with previous mental health disorders. Conclusions: Insufficient maternal education, along with a complicated birthing process requiring infant hospitalization, both contribute to elevated levels of postpartum anxiety.
