The 2024 Mj 7.6 Noto Peninsula, Japan earthquake caused by the fluid flow in the crust

On January 1, 2024 ​at 16:10:09 JST, an Mj 7.6 earthquake struck the Noto Peninsula in the southern part of the Sea of Japan. This location has been experiencing an earthquake swarm for more than three years. Here, we provide an overview of...

Changes in the Association between GDP and Night-Time Lights during the COVID-19 Pandemic: A Subnational-Level Analysis for the US

Night-time light (NTL) data have been widely used as a remote proxy for the economic performance of regions. The use of these data is more advantageous than the traditional census approach is due to its timeliness, low cost, and comparabili...

برآورد احتمالاتی توزیع بار در واحدهای فرآوری مواد معدنی با روش زنجیره مارکف

در روش‌های مرسوم موازنه جرم، برای تعیین عیار فلز، درصد جامد و توزیع دانه‌بندی نمونه‌برداری در مسیرها (شاخه‌ها) انجام می‌شود و در نهایت خطاهای مربوط به آنها سرشکن می‌شود. در این روش‌ها، برای هر واحد فرآوری (تجهیزات کارخانه)، در خصوص مقدار با...

Air distribution to reduce nitrogen oxide emissions in the furnace of a boiler with tangential combustion scheme

Relevance. Determined by the importance of analyzing the combustion characteristics and factors affecting the emission of nitrogen oxides (NOx) in the furnace chamber of pulverized coal-fired power boiler unit when installing tertiary air n...

The emission factor of volatile isoprenoids: stress, acclimation, and developmental responses

The rate of constitutive isoprenoid emissions from plants is driven by plant emission capacity under specified environmental conditions (<i>E</i><sub>S</sub>, the emission factor) and by responsiveness of the emissio...

DESENVOLVIMENTO DE UMA TIPOLOGIA HIDROGEOMORFOLÓGICA DE NASCENTES BASEADA EM ESTATÍSTICA NEBULOSA MULTIVARIADA

As nascentes de cursos d’água são sistemas hidrogeomorfológicos complexos, caracterizados por uma grande variabilidade de seus elementos estruturantes. Esta heterogeneidade ainda pouco conhecida cria dificuldades para os processos de gestão...

The cause of high intensity of seismicity in Ukraine

In the article, the earthquake near Sumy is considered in detail. According to the authors, this earthquake occurred under the influence of several stress regimes. At the regional level: it is related to the transfer of stresses from the Vr...

Structural Properties of Syngenetic Ice-Rich Permafrost, as Revealed by Archaeological Investigation of the Yana Site Complex (Arctic East Siberia, Russia): Implications for Quaternary Science

Ice-rich syncryogenic (termed “Ice Complex”) deposits are common in northern East Siberia and constitute the most important feature of the Quaternary geology of the region. The Ice Complex formed throughout the Late Pleistocene and not only...

Metallogenic potential and prospecting of orogenic gold deposits in the Shuihouling area of the Dabie Orogenic Belt: A geochemical evidence from stream sediment anomalies

The Shuihouling ductile shear zone, located in the core of the Dabie Orogenic Belt spanning Anhui and Hubei provinces, is a key structural unit with notable mineral potential. Situated within the Wudang-Tongbai-Dabie Mo-REE-Au-Ag-Pb-Zn poly...

Stress-dilatancy properties for fiber-reinforced sand

It is observed that randomly distributed polypropylene fibers act to interlock particles and thus improve the mechanical behavior of the reinforced soils. The polypropylene fiber inclusion clearly increases the shear strength of soils, and ...

Underground Gas Storage Process Optimisation with Respect to Reservoir Parameters and Production Equipment

The storage of natural gas in geological structures such as depleted fields, aquifers and salt caverns plays an important role in a gas supply system as it balances the fluctuation of gas demand and price. Hydraulic loss due to fluid flow t...
