In the process of its activities, SPBU (General Fuel Filling Station) X has the risk of fire and explosion because there is storage and distribution of flammable liquid fuel, one of which is Pertamax. Therefore, it is necessary to evaluate the risk control of the incident in order to reduce the losses incurred. This study aims to determine the risk of fire and explosion, as well as the value of business interruption (BI) or the value of possible losses suffered in the event of a fire and explosion. The risk assessment method used is the Dow's Fire and Explosion Index. The results of the study indicate that the potential for fire and explosion or the value of the fire explosion index (F&EI) is 110.828. This figure shows that the level of potential fire and explosion hazard in the Pertamax storage tank with a capacity of 21,694 liters at SPBU X is classified as Intermediate. The exposure radius is 28.39 meters and the damage factor to the pertamax buried tank is 63%. The large area of ​​the Exposure is 24 m2 with the exposed area as large as the volume of the bunker building of 96 m3. This means that pertamax containment tanks require special safety and security attention in order to reduce the value of the risk level. The value of the loss suffered by the company in the event of a fire and explosion in the Pertamax tank is Rp. 403.908076.97

El estudio del Derecho en las oposiciones: posibles aportaciones a la vida universitaria
Authors: Vigil de Quiñones Otero Diego 
Published: November 2023

Las pruebas selectivas para la función pública u oposiciones, son un ámbito donde se produce desde siempre un estudio muy elevado del Derecho. En la preparación de dichas pruebas se siguen una serie de prácticas como repetir, entrenarse para un examen concreto, centrarse en dominar un temario condensado o especializarse en una sola materia que dan grandes frutos y no son siempre seguidos en la Universidad. Resulta asimismo interesante destacar que gran parte del éxito que produce la formación jurídica de los opositores radica en el papel que asumen los maestros (más empático, con diferentes incentivos y más apoyado en la comunicación oral y el trato individualizado) y en el grado de complicidad y colaboración que se da entre los opositores.The selective exams for the achievement of a public function, also called oppositions, are an area in which we always find a very advanced study of Law. In preparing these exams, exercises such as repeating, training for a specific test, focus on dominating a condensed syllabus or specialize in a single subject produce great results, but are not usually implemented in University. It is also interesting to note that much of the success which produces the legal training of the applicants for the oppositions lies in the role assumed by teachers (more empathetic with different incentives and more supported on oral communication and individualized treatment than usual) and the degree of complicity and collaboration that occurs among opponents .

Abstract
The purpose of this article is to present a model for simultaneous optimization of pricing, marketing, distribution and sales decisions. Due to the high importance of time and costs along the chain, this model will be very attractive. In previous studies, these decisions have not been considered simultaneously. This paper introduces a bi-objective model including utility maximization and profit maximization. Then it was solved using LP metric method in GAMS optimization software and Gurobi Optimizer in Python environment. After solving the model, the decision variables have been obtained and the model has been subjected to sensitivity analysis. Based on the results obtained, it can be concluded that optimizing distribution network elements simultaneously saves time and money and improves distribution network performance. A trade-off matrix and Pareto chart is ​​provided in which the numbers on the main diagonal represent the most optimal state for each objective. In addition, a comparison was made between the results of the GAMS and Gurobi Optimizer in the Python showing that in larger sizes the Gurobi Optimizer delivers the desired results in a more reasonable time. Also, the results show the sensitivity of the model to the competitors' prices.

Published: November 2023

Abstract
In todays increase in population at metro cities there is a need in development of urban transport infrastructures. Due to development in urban transportation, many cities are proposed with metro structure to facilitate the public with modern transport systems. Since the metro cities are highly populated with congested traffic, development of transportation facility with isolated infrastructure for different transportation system is a major challenge. To overcome these issues, the transportation infrastructures can propose with integrated transportation structures like double decker highway structure, double decker metro with highway structures to facilitate the public with modern transport systems. In one of the metro projects at Chennai in India, a double decker integrated elevated viaduct is proposed with a first level highway traffic and second level with metro traffic. In highway bridges, simply supported superstructure with expansion joint is the conventional practice. But, in these conventional type with expansion joint for each span leads to discomfort to riders and huge maintenance issues. There are many studies and development in highway structure with the reduced number of expansion joint by making structures with deck continuity, diaphragm continuity, integral structures are undergoing. However, in integrated structure with single pier / substructure carrying both metro superstructure and highway superstructure is generally proposed with simply supported spans. In this paper, the study on behavior of integrated double decker viaduct with metro and highway structure is endeavored with deck continuity through link slab at highway level superstructure to avoid many numbers of expansion joints and thereby to provide comfort riding to the public, cost saving during construction and less maintenance cost. An analytical study using finite element-based MIDAS CIVIL software is performed to study the behavior of deck continuity at highway level superstructure in integrated double decker bridge for the thermal effect, other secondary effects like creep, shrinkage and for live load forces. In this study, the structural parameters, boundary conditions are considered as per Indian Railway Standards, Indian Road Standards & other applicable Indian Standards, and the rail structure connectivity with deck for unballasted conditions are followed as per UIC 774-3R. This paper discusses the behavior of deck continuity in double decker integrated structure and based on the optimum force to the substructure, four span deck continuity is proposed in this double decker integrated viaduct with first level deck carrying road system and second level deck carrying metro system.

Abstract
Auxin, as a vital phytohormone, is enriched in the vascular cambium, playing a crucial role in regulating wood formation in trees. Despite its significance, the molecular mechanisms underlying the influence of auxin on wood development remain elusive. In this study, we report a transcription factor, PLETHORA 5 (PLT5), whose expression was specifically activated by auxin signalling in the vascular cambium. PLT5 was found to regulate cell expansion and lignification of fibres in poplar. Genetic experiments confirmed the noncell-autonomous regulation of auxin signalling from the vascular cambium and revealed the necessity of PLT5 protein mobility to mediate this process. Remarkably, PLT5 proteins specifically inhibit the initiation of fibre cell wall thickening by directly repressing SND1 genes. This study unveils a sophisticated model wherein the auxin-PLT5 signalling cascade intricately regulates wood fibre development in poplar by fine-tuning the thickening of fibre cell walls.
A Comparison of cryoballoon and Radiofrequency ablation as redo procedure-ablation in Patients with recurrent Atrial fibrillation after cryoballoon-ablation
Authors: Schehab Wasim , schloemicher Markus , Kciku Gresa , Pradhan Snehasis , Trappe Hans-Joachim , Strauch Justus 
Published: November 2023

Abstract
Background:
A significant proportion of patients with recurrent atrial fibrillation (AF) require repeat radiofrequency (RFC) or cryoballoon (CB) ablation after the blanket period (90 days) following the initial cryoablation. However, little is known about the efficacy of pulmonary vein isolation using either of the technique as a redo procedure. Therefore, the present study aimed to analyze the electrophysiological characteristics of pulmonaary veins (PVs) during redo ablation procedures and clinical outcomes in patients undergoing CB-vs-RFC ablation as redo procedures.
Methods:
61 Patients with paroxysmal and persistent atrial fibrillation were retrospectively included in the analysis. The number and location of reconnected PVs, another arrhythmic drug before the reablation, structural heart disease and antiarrhythmic drugs were determined.
Results:
Before the redo procedure, paroxysmal atrial fibrillation was the predominant recurrent arrhythmia (60%). However,20 patients (70%) had paroxysmal atrial fibrillation in the RFC and 16 Patients (50%) in the CB group 29 Patients (47,5%) underwent a catheter ablation with radiofrequency, and 32 Patients (50,8%) underwent a catheter ablation with a cryoballoon. The Median of reablation occurred of 238 and 323 days (P= 0,0008). The Number of the reconnected PVs was 42 in the RFC group and was 99 in the CB group, which means the number of lesions applied during the redo Procedure was significantly greater in the CB cohort. The reconnection was driven by more reconnection in the left superior PV. After Reablation, there were no differences in the antiarrhythmic drug between the cohorts, but significantly more patients required amiodarone in the RFC Cohort.
Conclusion:
This analysis revealed an overall success rate of 70% in patients with recurrent atrial fibrillation who underwent a redo treatment using either radiofrequency or cryoballoon, implying equivalent performance effectiveness between both modalities.
Evidence for small-scale segmented fault rupture along the East Anatolian Fault during the Mw 7.8 2023 Kahramanmaras earthquake
Authors: Palo Mauro , Zollo Aldo 
Published: November 2023

Abstract

The rupture front of the first ∼25 s of the 2023 Mw 7.8 Kahramanmara¸s earthquake is tracked using the P-wave polarization vector vs time as measured at the dense three-component accelerometer network surrounding the slipping fault. We find a coherent increase of the spatially variable rupture velocity along portions of the earthquake fault zone where high coseismic slip has been previously mapped by kinematic source imaging studies. This is clearly detected in a domain of the Pazarcik segment of the East Anatolian Fault located at 70 km NE of the mainshock epicenter where the rupture velocity rises to super-shear values. This domain spatially matches the part of the Pazarcik segment where most micro-earthquakes nucleate in the inter-seismic phase and edges at north a nearly aseismic domain. We postulate the existence of velocity weakening subsegment on the Pazarcik fault sandwiched between velocity strengthening domains and/or mechanic barriers to the fault slipping.
