This study aimed to design a learning path which can help students to understand fractions based on Pendidikan Matematika Realistik Indonesia (PMRI) approach.The subject is 30 students of 4th grade of PP Qodratullah Langkan.Method of this research is design research, Hypothetical Learning Trajectory (HLT) developed from learning activity series usi
Abnormalities in hydraulic conditions inside a water distribution network are strongly related to the deterioration of drinking water quality.Leaking pipes and valves cause changes to the hydraulic conditions and allow the entry of impurities into the distribution system.Sudden flow and pressure shocks can detach soft deposits and biofilms from the
This paper deals with dynamic industry scheduling problem in agri-food production.The decision-making study in this paper is articulated around the management of perishable products under constrained resources.The scheduling of logistics operations is considered at the operational level.Two metaheuristics are proposed to solve dynamic scheduling un
Abstract Akkermansia muciniphila, a promising candidate for next-generation probiotics, exhibits significant genomic diversity, classified into several distinct clades (AmI to AmIV).Notably, a single Akkermansia clade Sharpeners tends to predominate within individual hosts, with co-occurrence of different clades being rare.The mechanisms driving su
Abstract We study the inclusion of new heavy fermions on complex Battery Pack scalar dark matter (DM) phenomenology within gauged two Higgs doublet model (G2HDM).We find that for DM mass above 1 TeV, heavy quarks coannihilations into the Standard Model (SM) quarks and gluons dominate the thermally-averaged cross section relevant for the relic abund
