The Ronggojalu spring, with a discharge intensity of more than 3,000L/second, makes it one of the spring with the most significant discharge in Indonesia and is the main supplier of clean water for the City of Probolinggo. From the observation of topographic maps, the existence of this spring forms a lineament with Paras Spring and Sumber Kramat with a direction of Northeast to Southwest. The presence of this lineament can indicate the existence of geological structures that play a role in the formation of spring. In addition, this lineament is in the same direction as the active Probolinggo fault identified by PUSGEN (Pusat Studi Gempa Nasional). This study aims to identify the presence of geological structures in the lineament using satellite gravity data GGMplus (Global Gravity Model) and Remote Sensing. This data is quite efficient and effective in identifying subsurface geological structures. With the SVD (Second Vertical Derivative) analysis, the residual anomaly results from the second derivative value of the Bouger anomaly so that it can show the density contrast value as an indication of the geological structure. From the results of the interpolation of satellite gravity data in the study area, the CBA (Complete Bouguer Anomaly) value range is -16.8 – 4.8 mGal. The analysis of SVD and FHD shows a significant contrast different values along the fault line that passes through the spring. The lineament density processing also shows a weak zone around the fault zone, indicating the continuity in that zone. The existence of a fault under this spring indicates the influence of the fault on the formation of Ronggojalu Spring, Paras Spring, and Keramat Spring. In addition, it is estimated that this fault is a continuation of the active Probolinggo fault.

Green Chemistry (GC) is an issue that is very relevant to chemistry subjects in senior high schools. Chemistry subject is closely related to the environment as one of the pillars of sustainable development. This certainly contributes to the possibility integration of green chemistry principles into chemistry learning. This exploratory research aims to describe the principles of GC that allow it to be integrated into chemistry learning in grades X and XI; describes the high school teacher's and students' perceptions and understanding of GC and its principles in chemistry learning. The subjects in this study were 230 students who were selected purposively from five Senior high schools. Totally 40 chemistry teachers were purposively used as research subjects from a number of high schools throughout South Sulawesi. The instrument used was ten items of teacher's perception questionnaires, while the students' perception questionnaire consisted of twelve items. Guidelines for interviewing teachers and students were used to describe more deeply about their understanding of GC. All instruments have been validated by two experts. The results of the exploration of material elements for phases E and F show that five GC principles can be integrated into learning chemistry. In general, the teacher's perception of GC is good, which assumes that GC is an environmentally friendly concept. Understanding of the five principles of GC for students and teachers is in the moderate and poor categories. This shows the importance of integrating GC principles in the form of positive habits in chemistry learning.

Published: October 2023

RELEVANCE. Unbalance of loads adversely affects both the work of consumers and the electrical network itself. This phenomenon leads to a decrease in the efficiency of the processes of transmission and distribution of electrical energy due to the appearance of additional losses. Balancing of loads in electrical networks of 0.4 kV is carried out both at the design stage of networks and during their operation. At the design stage, they try to evenly distribute the loads across the phases. The authors of the article solve the actual problem of distributing single-phase electrical consumers at the stage of designing a power supply system to analyze the total share of additional losses from unbalance in the structure of total losses in distribution networks of 0.4 kV.THE PURPOSE. To consider the problem of unbalance of loads in electrical 0.4 kV networks, causing additional losses of electricity.

Develop an algorithm for single-phase power consumer distribution, using arrays of instantaneous values of the current strength of individual electrical receivers as initial data. It stipulates calculating the best distribution of power consumers across the phases of lines L1, L2, L3 using the minimization of the load unbalance impact on the losses in power grid elements used for the electric power transfer.METHODS. To solve this problem, the authors employed the complete enumeration method implemented with a tertiary numerical system used to code power consumer distribution across the power supply grid phases. The coefficient accounting for the unbalance of load distribution across power grid phases is used as the target function.RESULTS. The developed algorithm can be applied as an external plug-in for the design software package to distribute the power consumers of one of the rooms in a BIM office building. The developed algorithm is compared to the existing widely-used approaches to single-phase power consumer distribution in power grids.CONCLUSION. The developed algorithm allowed producing brand-new engineering solutions while developing a design document for the power supply grid (design and detailed documentation stage). They help improve the efficiency of electric power transmission by reducing additional losses caused by unbalanced loads.

Objective:Scaphoid and lunate fractures have a relatively high incidence rate. Traditional carpectomy and carpal arthrodesis in the treatment of carpal osteonecrosis will lead to many complications. Three-dimensional (3D) printed tantalum has good biocompatibility and can be designed to match the patient’s personalized anatomical carpal structure. This study aims to investigate carpal function and prosthesis-related conditions after carpal bone replacement using 3D printed tantalum prostheses.Methods:From July 2020 to January 2022 at our center, seven patients with osteonecrosis of the carpus received carpal bone replacement using 3D printed tantalum prosthesis. The Disability of the Arm, Shoulder and Hand (DASH) score and patient satisfaction, as well as the Mayo Wrist Scores (Cooney method, modified Green, and O’Brien wrist score), were used to evaluate the preoperative and postoperative wrist function of patients. The Visual Analog Scale (VAS) pain scores were also recorded before and after surgery. The angles of flexion, dorsiflexion, ulnar deviation, and radial deviation were measured using an arthrometer. The grip strength and pinch strength of the operated hand after carpal bone replacement and the contralateral healthy carpus were measured using a dynamometer. Radiographs were taken to confirm the condition and complications of the tantalum prosthesis.Results:All seven patients were followed for 19.6 ± 2.7 months. At the last follow-up, the grip strength of the operated wrist joint after carpal bone replacement was 33.4 ± 2.3 kg, the pinch strength was 8.9 ± 0.7 kg, the flexion was 54.6° ± 0.8°, the dorsiflexion was 54.7° ± 1.7°, the ulnar deviation was 34.6° ± 1.9°, and the radial deviation was 25.9° ± 0.8°, all of which showed no statistically significant difference with the contralateral healthy carpus (p&gt; 0.05). There were significant differences in the VAS, DASH, and MAYO scores between the preoperative and the last follow-up (p&lt; 0.01). Patients had reduced postoperative pain and improved wrist function and range of motion (ROM), and the tantalum prostheses were stable.Conclusion:The 3D printed tantalum brings us new hope, not only for hip or knee replacement, but also for joint replacement of other complex anatomical structures, and patients with other irregular bone defects such as bone tumors and deformity, which could realize personalized treatment and precise medicine.

PurposePatients with digestive system cancers (DSCs) are at a high risk for hospitalizations; however, the risk factors for readmission remain unknown. Here, we established a retrospective cohort study to assess the association between metabolic obesity phenotypes and readmission risks of DSC.Experimental designA total of 142,753 and 74,566 patients at index hospitalization were ultimately selected from the Nationwide Readmissions Database (NRD) 2018 to establish the 30-day and 180-day readmission cohorts, respectively. The study population was classified into four groups: metabolically healthy non-obese (MHNO), metabolically healthy obese (MHO), metabolically unhealthy non-obese (MUNO), and metabolically unhealthy obese (MUO). Multivariate Cox regression analysis was used to estimate the effect of metabolic obesity phenotypes on DSC readmission.ResultsThe MUNO phenotype had 1.147-fold (95% CI: 1.066, 1.235; p &lt; 0.001) increased 180-day readmission risks in patients with neoplasm of the upper digestive tract. The MUNO phenotype had 1.073-fold (95% CI: 1.027, 1.121; p = 0.002) increased 30-day readmission risks and 1.067-fold (95% CI: 1.021, 1.115; p = 0.004) increased 180-day readmission risks in patients with neoplasm of the lower digestive tract. The MUNO and MUO phenotypes were independent risk factors of readmission in patients with liver or pancreatic neoplasm. Metabolic obesity status was independently associated with a high risk of severe and unplanned hospitalization within 30 days or 180 days.ConclusionBoth obesity and metabolic abnormalities are associated with a high risk for the poor prognosis of DSC patients. The effect of metabolic categories on the short- or long-term readmission of liver or pancreas cancers may be stronger than that of obesity.
