The Indonesian region is affected by the monsoon system, which leads to a rainy season in December-March and dry June-September. Global warming caused human activities increasing risk of extreme climate events like floods, droughts, etc. study aims analyze trends correlations temperatures South Sumatra coastal area its relationship with DMI Nino 3.4 indices. four-stage research methodology incl...

An increase in extreme temperature events could have a significant impact on terrestrial ecosystems. Reanalysis data are an important set for estimation mountainous areas with few meteorological stations. The ability of ERA5-Land reanalysis to capture the index published by Expert Team Climate Change Detection and Indices (ETCCDI) was evaluated using observational from 17 stations Qilian Mounta...

Penggunaan machine learning menjadi salah satu bidang yang banyak digunakan seiring berkembangnya zaman. Melakukan prediksi dengan baik pada suatu data dapat dibantu teknik dan model learning. Regresi terbaik dalam memprediksi data. Tujuan penelitian ini yaitu untuk memanfaatkan menggunakan regresi sebuah baik. Tahapan melakukan meliputi pengumpulan materi, analisis perancangan, uji coba, imple...

We report on the progress a first generation of realistic size metascintillators for time-of-flight PET. These heterostructures combine dense LYSO or BGO plates, interleaved with fast scintillator layers producing bunch prompt photons from energy leakage recoil photoelectric electron. From Geant4 simulation sharing distribution between and 42 LYSO-based BGO-based configurations, detailed study ...

The cold regions of China (CRC) are important and vulnerable freshwater recharge areas on land, any changes in them related to the survival millions people East Asia. However, for nearly half a century, regions, extreme temperature response global warming is still poorly understood. In this study, we systematically studied since 1961 discussed possible circulation factors detail. results showed...

In this article, the dynamic thermal rating assessment method of oil-immersed power transformer with multiple operating conditions is proposed, considering constraints hot spot temperature (HST), top oil temperature, losses life and maximum allowable current on-load tap changer (OLTC) or bushing, which can determine load curves under different give most sensitive to limit capacity. To improve a...

Background: Lead is a toxic element which causes acute, subacute or chronic poisoning through environmental and occupational exposure. The aim of this study was to investigate clinical and laboratory abnormalities of chronic lead poisoning among workers of a car battery industry. Methods: Questionnaires and forms were designed and used to record demographic data, past medical histories ...

Abstract A measure of how easy it is to transport, cast, compact and surface finish fresh concrete without any segregation directly proportional workability concrete. The consistency indirectly measures its workability. VeBe test, slump test compaction factor are some the methods that can be used study quick determination strength properties an important element on large construction sites for ...

The 2021 IPCC report found that most studies show declining trends for the global diurnal temperature range (DTR) since 1950s, decreasing mainly during 1960–1980. This issue is revisited here using an up-to-date in-situ data set, Hadley Center Integrated Surface Database, constrained by rigorous station selection conditions. observed DTR trend was to reverse 1980–2021, increasing significantly ...
