La dilatación gástrica aguda se fundamenta por dos teorías, la mecánica que es explicada por el síndrome de arteria mesentérica superior y la atónica; que es producto de una condición médica en la que el estómago progresivamente se vuelve hipotónico y se sobre distiende aún en ausencia de una causa mecánica obstructiva; con mayor frecuencia la dilatación gástrica aguda se presenta en pacientes con trastornos de la alimentación; y puede conllevar a una complicación rara pero letal como la perforación gástrica; presentamos el caso de una paciente de 18 años, quien acude al servicio de emergencia de nuestro hospital ,con dolor abdominal agudo, es intervenida quirúrgicamente, donde se encuentra perforación de la pared gástrica anterior, se le realiza una gastrectomía parcial proximal, y se envía el espécimen para estudio patológico. La histopatología muestra necrosis transmural predominantemente en fondo gástrico.
Pore-Scale Numerical Investigations of the Impact of Mineral Dissolution and Transport on the Heterogeneity of Fracture Systems During CO2-Enriched Brine Injection
Authors: You Jiahui , Lee Kyung Jae 
Published: January 2022

Summary
Carbon dioxide (CO2) storage and sequestration is regarded as an effective approach to mitigate greenhouse gas emissions. While injecting an enormous amount of CO2 into carbonate-rich aquifers, CO2 dissolves in the formation brine under the large pressure and the subsequently formed CO2-enriched brine reacts with the calcite. Reaction-induced changes in pore structure and fracture geometry alter the porosity and permeability, giving rise to the concerns of CO2 storage capacity and security. Especially in the reservoir or aquifer with natural fractures, the fractures provide highly permeable pathways for fluid flow. This study aims to analyze the acid-rock interaction and subsequent permeability evolution in the systems with complex fracture configurations during CO2 injection by implementing a pore-scale Darcy-Brinkman-Stokes (DBS) reactive transport model. The model has been developed by expanding the functionality of OpenFOAM, which is an open-source code for computational fluid dynamics. A series of partial differential equations are discretized by applying the finite volume method and then solved sequentially. Different fracture configurations, such as fracture length, density, connection, and mineral components, have been considered to investigate their impacts on the dynamic porosity-permeability relationship, dissolution rate, and reactant transport characteristics during CO2 storage. Various mineralogical compositions were investigated to compare their effects on the reactive transport and subsequent system behavior induced by water-rock interactions. The investigation revealed several interesting findings. We found that calcium (Ca) ions concentration was low in the poorly connected area at the initial time. Because CO2-enriched brine saturated the system and reacted with calcite, Ca ions started accumulating in the system. However, Ca ions barely flowed out of the poorly connected area, and the concentration became high. Lengths of branches mainly influenced the dissolution rates, while they had slight impacts on the porosity-permeability relationship. While fracture connectivity had an apparent influence on the porosity-permeability relationship, it showed a weak relevance on the dissolution rate. The calcite-clay fracture-matrix system showed a slow increase of permeability because CO2-enriched brine was injected. These microscopic insights can help enhance the CO2 sealing capacity to guarantee environmental safety.
A balanced watershed decomposition method for rain-on-grid simulations in HEC-RAS

Published: January 2022

Abstract
Rain-on-grid simulations for the modeling of 2D unsteady flows in response to precipitation input are implemented in Hydrologic Engineering Center's River Analysis System (HEC-RAS) software by means of a finite volume method and a sparse parallel linear solver running on a unique processor. Obviously, this may fail due to memory shortage when the discretization yields too large linear systems. Such simulations are good candidates for the design of partition and domain decomposition methods for the modeling of very large catchments by means of hydrological sub-units. Thinking in load-balanced computations, the proposed area-balanced partition method is based on the flow accumulation information. Implemented in HEC-RAS, the domain decomposition method comprises 2D–1D models combining 2D sub-unit meshes to 1D channels for extracting outflow data from upstream units and passing the information to downstream units. The workflow is automated using the HEC-RAS Controller. As a case study, we consider the French Saar catchment (1,747 km2). The new partition methods demonstrate a better equilibrium for sub-basin areas and the computational load for the sub-problems. The total computational time is substantially reduced. Domain decomposition is required for carrying rain-on-grid simulations over the Saar watershed (2,800,000 elements). The resulting discharge and flood maps show very good agreements with available data.

Abstract
Achieving high-quality economic development under the new development pattern has become an inevitable requirement for China's economic development. Correctly calculating the value of water resources and optimizing the price mechanism of water resources is one of the important guarantees for promoting the high-quality development of the regional economy. Based on this fact, this paper takes Hubei Province as an example to construct a coupling relationship model between water resources and economic high-quality development and to evaluate the coupling coordination between the two. And then, the fuzzy comprehensive evaluation model is used to evaluate the value of water resources in Hubei Province, and recalculate its water price. The results show that Hubei province now is a lagging development of water resources, and the current water price is far lower than assessed. The government should improve the mechanism of water price which should be driven by innovation to adjust the water use structure, finally achieve high-quality economic development of Hubei Province.

Abstract
The scarcity of water resources has posed serious threats to the sustainable development of agriculture. China is a largely agricultural country with a large population, and agricultural water consumption accounts for more than 50% of the total water consumption. The application of water-saving irrigation is the main way to realize the sustainable development of water resources and economics. To comprehensively improve crop water-use efficiency and reduce agricultural water consumption, the Chinese central government have promulgated a series of agricultural water-saving policies since 2012, such as strengthening water management, increasing financial investment, and strengthening project construction and operation management and protection. Taking Jiangsu as an example, this paper reviews the main water-saving policies and measures of governments after 2012, as well as the conflicting interest between different water-saving participants. Results showed that, through water-saving policies and measures, its effective utilization coefficient of agricultural irrigation water (EUCAIW) has increased from 0.59 in 2014 to 0.614 in 2019. By 2019, the area of irrigated arable land controlled by water-saving technologies is 2.848 million hectares, accounting for 67.8% of the irrigated arable land area in Jiangsu. Jiangsu's water-saving policies have been implemented well, and it has guidance on water-saving reform work in other places.

Abstract
In order to reduce the membrane pollution of ultrafiltration caused by natural organic matter and improve the treatment efficiency, electroflocculation/oxidation is used as the premembrane treatment method. The membrane specific flux attenuation characteristics was compared and analyzed under the conditions of direct ultrafiltration and electroflocculation/oxidation-ultrafiltration. Combined with the analysis of the reversibility of membrane fouling, the mechanism of electroflocculation/oxidation pretreatment to alleviate ultrafiltration membrane fouling was evaluated, and the membrane pore clogging model was used to fit the fouling law. The results show that, in the continuously fed filtration experiment, the electroflocculation/oxidation process involved in the pretreatment and the direct ultrafiltration membrane filtration decreased the ultrafiltration membrane flux to 79.1% and 28.5%, respectively. The reversible resistance generated by ultrafiltration and electroflocculation/oxidation-ultrafiltration processes accounted for 37.70% and 62.26% of their total pollution resistance, whereas the irreversible resistance generated accounted for 47.30% and 12.40%, respectively. Meanwhile, the direct correlation between the the flux dropped and complete clogging became less than that of the ultrafiltration process. The pretreatment significantly strengthened irreversible fouling resistance of the membrane pores. The membrane permeation flux was significantly increased after the electroflocculation/oxidation pretreatment.
The Great Power of Prediction from a Massive Photon Hypothesis.
Authors: CORNIERE Henri 
Published: January 2022

Mass, an inherent property of matter, is calculated directly for the photon particle from the very classical principles of the kinetic theory of gases. That concept of photon mass is nearly as old as physics itself and in fact nothing prevents this approach to be carried out for a so-called quantum particle, not even its minute size. It is not an end result with no perspective nor other outcome. Quite the opposite, a single ponderable tiny photon frees the mind of old ways of thinking and opens up new paths to a broad field of investigation where the very large can then be described and explained by the very small. This reality of a non-zero mass suddenly shows up in the interpretation of many experiments which become clear and simple to comprehend. Besides, that same key particle has the potential to unlock and solve some long lasting major observational issues or enigmas. All this converges upon its acknowledgment and acceptance.
