Structures in chemical and petrochemical facilities are often located in areas that may be subjected to blast loading. Occupied buildings typically have non-structural components located along the interior of the exterior walls and roof such as windows, doors, wall mounted AC units, lights, furniture, storage racks, hanging equipment, and loose articles. Occupants of buildings subjected to accidental explosions may be injured from glass fragments and interior non-structural items becoming projectiles and impacting building occupants. As a pressure wave from a blast impacts the exterior of a building, the wall and roof components are rapidly accelerated inward. Equipment or contents mounted on or in contact with the exterior façade are also accelerated and may be dislodged and projected as debris. Items anchored to the ceiling structure can be thrown vertically from the initial forward d...

A digital image may contain objects that can be made up of multiple regions concerning different material properties, physical or chemical attributes. Thus, segmented simplicial meshes with non-manifold boundaries are generated to represent the partitioned regions. We focus on repairing non-manifold boundaries. Current methods modify the topology, geometry or both, using their own data structures. The problem of modifying the topology is that if the mesh has to be post-processed, for instance with the Delaunay refinement, the mesh becomes unsuitable. In this paper, we propose alternatives to repair non-manifold boundaries of segmented simplicial meshes, among them is the Delaunay based one, we use common data structures and only consider 2 and 3 dimensions. We developed algorithms for this purpose, composed of the following tools: relabeling, point insertion and simulated annealing. Thes...

This paper presents Best Theory Diagrams (BTDs) constructed from non-polynomial terms to identify best shell theories for the free vibration analysis of laminated and sandwich shell. The shell theories have been constructed using Axiomatic/Asymptotic Method (AAM). The refined models are implemented following the compactness of a unified formulation developed. The governing equations are derived from the Hamilton’s Principle. NavierType solution technique is used for solving the eigenvalue problem of simply supported shell. The BTDs use 3D equilibrium solutions as a reference. The BTDs built from non-polynomial functions are compared with Maclaurin expansions. The results are compared with Layerwise solutions. Cylindrical and spherical shells with different layer-configurations are investigated. The results demonstrate that the shell models obtained from the BTD using non-polynomial ter...

Disordered crystalline Fe50Mn25+xSn25?x alloys, with x =-1.25, 0.0, 2.5, 5.0, 7.5 (close to the full-Heusler alloys), were arc-melted in a high purity argon atmosphere and the molten pellets were individually sealed in quartz tubes also under argon atmosphere. Subsequently, they were annealed at 1173 K for 4 days, being finally quenched in a bath with cold water. Structural and magnetic properties have systematically been studied using X-ray diffraction,57Fe, and119Sn Mössbauer spectroscopies, and magnetization measurements recorded at room temperature. Rietveld refinement of the X-ray diffraction patterns of the annealed samples with x =-1.25 and 0 has revealed the presence of two hexagonal crystallographic phases: (i) a chemically disordered solid solution identified as ??(Fe/Mn)3Sn (majority fraction) and (ii) the ??Fe5Sn3 intermetallic compound (minority fraction). For samples with ...

One of the main problems of athletes and people who practice sports for passion is dehydration, this happens because the human body to avoid overheating its structure generates sweat that cools the body and is the sweat where they are lost the mineral sales vital for our body. The human body generates a feeling of fatigue (fatigue) due to dehydration, with the consequence that people can not perform as much as possible and that they are prone to muscle injuries due to the loss of mineral salts such as sodium and potassium that serve a correct absorption of water in our body. Due to these reasons and that according to Euromonitor (2015); the isotonic beverage market is growing every year, it is proposed to study the realization of a project for the manufacture of a drink of this type that contains natural protein and that does not require further refinements, or processes for its preparat...

The present study analyzes the characterization of adhesion properties in intermediate layers of asphalt pavement, a critical factor influencing road durability and performance. The research is based on a systematic review of scientific literature, highlighting different methodologies for evaluating interlayer bonding, experimental tests, and international standards such as AASHTO, ASTM, and MTC regulations. A comparative analysis was conducted between samples obtained from the “Improvement of the Santa Maria - Santa Teresa - Hydroelectric Machu Picchu Bridge Road” project and laboratory simulations using the LOTTMAN test. The results demonstrate that the amount of tack coat significantly affects interlayer adhesion. Experimental tests confirmed that a tack coat application rate of 0.4 l/m² provides optimal indirect tensile strength (TSR) values, improving mechanical bonding between...

This study examines the effect of technostress on boreout syndrome among municipal workers in Lambayeque, Peru, addressing a significant gap in the literature regarding the relationship between technological stressors and workplace disengagement. Using a quantitative, correlational, non- experimental design, data were collected from 300 municipal employees through validated scales measuring technostress (RED-TIC) and boreout syndrome. Structural equation modeling with partial least squares (PLS-SEM) was employed to test the hypothesized relationships. Contrary to theoretical expectations, results revealed a significant negative relationship between technostress and boreout syndrome (β = −0.584; p < 0.001), with a large effect size (f² = 0.519). This paradoxical finding suggests that technological demands may serve as cognitive activators that protect against workplace boredom and dis...

In the global context, there is a growing trend to incorporate mechanisms for land value capture into public policies to address challenges associated with the financing of public transportation infrastructure. For a proper assessment, it is crucial to gather information on the impacts of public actions that generate value in private assets, and such information is scarce in the Peruvian context. The main objective of the research was to estimate the impact of Metro Line 1 on housing sales price around three stations in the San Borja - Surquillo district in Lima, Peru. A quantitative methodology was proposed, with an explanatory approach, non-experimental design, and cross-sectional design (2023), for a refined sample of 339 residencial properties surrounding the La Cultura, San Borja Sur, and Angamos stations of Line 1 of the Lima Metro using available information from real estate websi...

The Cachíos Formation of the Arequipa Sedimentary Basin is the most distinguishable lithostratigraphic unit of the Yura Group, due to its lithological attributes and its unusual deformational features. The Cachíos Fm. (± 603 m thick) is composed of interlayered very fine-grained siltstones and claystones, both dark gray to very dark gray. These sediments represent the Fl facies (cf. Miall 1985). It is common to find some intercalations of thin strata (<0.5 m) of gray-green quartz sandstones, and eventual thicker strata (up to ca. 12 m) of the same lithological material deformed as olistoliths. Such structures are frequently found with flexures, eventual folds, slumps, and normal non-sedimentary faults, and eventual siliciclastic dikes, which reflect a continuous process of deformation. Such facies association is representative for the Cachíos Fm., and it is due to its lithological...

This study investigates emotional involvement in romantic relationships through the Relationship Involvement Scale (RIS), emphasizing its validation and reliability in a Peruvian sample. Interpersonal relationship challenges underline the significance of emotional commitment for well-being. The RIS uniquely assesses this aspect, distinguishing it from love, satisfaction, and maintenance measures. Through meticulous validation involving translation and expert review, and a sample of 300 Peruvian young adults, the research confirms the RIS’s unidimensional structure and reliability. Factorial analysis refines the scale by eliminating low-loading items, while associations with relationship satisfaction validate its construct. Utilizing confirmatory factor analysis, the study highlights the positive link between involvement and satisfaction, suggesting the RIS’s utility in understanding ...

The evaluation of presence and origin of ground-ice in the non-glaciated peripheral areas of Nevado Corpuna can contribute to a more refined estimation of its real extent, as well as of the ongoing and recent transformation processes (i.e. permafrost aggradation/degradation). We carried out GPR surveys in sectors immediately outside the glacial tongues which diverge from the glaciated area, both on rock glaciers and debris-covered glaciers. The data acquisition was made with an unshielded antenna operating at a central frequency of 25 MHz, and according longitudinal and cross profiles. We defined a processing sequence particularly effective in removing in air-reflections generated by isolated blocks on the surface, and the numerous point-source diffractions. The signal-to-noise ratio consents a data imaging interpretable up to 25-30 m of depth, according to the estimated velocity of GPR ...
