This study was conducted from November 2018 to October 2019 in 8 forested streams the Haut-Nyong and Mvilla watersheds determine influence of substrates granulometry on benthic macroinvertebrates. The physicochemical analyses showed highly oxygenated, weakly mineralized slightly acidic waters. granulometric reveal 9 categories depending scale sand, sand+gravel or sand+mud. Sampling macroinverte...

The human promyelocyte leukemic cell line HL-60 secretes a glycoprotein factor which stimulates HL-60 and myeloid cell growth and colony formation in vitro. Functional and biochemical studies indicate this autostimulatory activity (ASA) is distinct from colony-stimulating factor (CSF) activities reported previously. Human CSF I, CSF II, and HL-60 ASA stimulated HL-60 growth and colony formation...

Microplastics have been detected all around the globe in freshwaters which are frequently used to produce drinking water. Therefore, contamination of raw water with microplastics that supplies treatment plants, and their removal efficiency is raising more concern interest. In present study, we evaluated microplastic a conventional plant (Geneva, Switzerland) contribution coagulation on filtrati...

This study investigates water-sand bursting disasters associated with fractured rock that affect safe mining in the areas of Western China. A broken seepage rheological test device was developed, and tests were conducted on multiple groups samples single-stage axial loading different load levels. When rheology each group stable, mixed fluid injected into at a certain pressure gradient to conduc...

A colony-stimulating factor (M-CSF) has been partially purified and concentrated from mouse yolk sac-conditioned medium (YSCM). M-CSF appeared to preferentially stimulate CBA bone marrow granulocyte-macrophage progenitor cells (GM-CFC) to differentiate to form macrophage colonies in semisolid agar cultures. By comparison, colony-stimulating factor (GM-CSF) from mouse lung-conditioned medium (ML...

Nonglacial deposits Artificial fill (Holocene)—Mud, sand, and gravel of varying proportions, possibly including foreign debris such as concrete, logs, timbers, or brick. Used for highway roadbeds and other construction. Thickness generally greater than 2 m. Mapped where fill substantially obscures or has altered original geologic deposit. Beach deposits (Holocene)—Soft sand, silt, and mud depos...
