Lake Chalco lies south of the Basin Mexico and has been subject studies related to Late Quaternary climate variability. In 2016, International Continental Scientific Drilling Program “MexiDrill Project” recovered a 520-m sediment record from Chalco. Magnetic susceptibility measurements revealed substantial changes in physical properties between 343 285 m depth, suggesting composition associated...

Zeta sedimentation ratio (ZSR) is a simple, rapid and reproducible test which is not influenced by variables like sex and anemia. There is good correlation with Westergren erythrocyte sedimentation ratio (ESR) in normal and hospital population. Limitation of packing force affects the use of the procedure in polycythemia and in patients with ZSR greater than 80%.

The neritic region of the Chaoshan plain is located on northeastern (NE) boundary South China Sea (SCS). Despite extensive research stratigraphic architecture and sedimentary processes within plain, neighboring area remains largely unexplored. In this study, we provide a new set ages seventeen quartz optically stimulated luminescence (OSL) dating results from four cores (SY2-2, SY3-1, SY3-2, HS...

Presence of salts in water has been one of the biggest problems of industrial equipment such as evaporators, boilers, and pipes. These salts gradually form scales on evaporators and boilers tubes and reduce their efficiency. Pretreatment processes are conducted to remove these salts; with sedimentation tanks being one of the essential equipment used in these processes. This study numerically si...

Fluvial features present around impact craters on Mars can offer insight into the ancient martian climate and its relationship to the impact cratering process. The widespread spatial and temporal distribution of surface ice on Mars suggests that the interaction between impact cratering and surface ice could have been a relatively frequent occurrence. We explore the thermal and melting effects o...

[1] To explain the much higher denudation rates and valley network development on early Mars (> 3.6 Gyr ago), most investigators have invoked either steady state warm/wet (Earthlike) or cold/dry (modern Mars) end-member paleoclimates. Here we discuss evidence that highland gradation was prolonged, but generally slow and possibly ephemeral during the Noachian Period, and that the immature valley...

[1] Field work and topography analysis show that remnant, local areas of a low-relief landscape or erosion surfaces are geographically continuous across the southeastern Tibetan Plateau margin. We correlate these remnant surfaces as a paleolandscape that formed at low elevation. Remnants of this paleolandscape are preserved because incision of the fluvial system has been largely limited to majo...

The development of paraglacial fans, studied in the upper Bhagirathi valley, Garhwal Himalaya, northern India, relates to the retreat of the Gangotri Glacier over the last 200 years. These fans demonstrate the speed by which mass movement and fluvial processes may lead to the modification and readjustment of the Himalayan landscapes during deglaciation. The paraglacial fans in this region grew ...

Modern river ecosystems undergo constant stress from disturbances such as bank stabilization, channelization, dams, and municipal, agricultural, and industrial water use. As these anthropogenic water requirements persist, more efficient methods of characterizing river reaches are essential. Benthic macroinvertebrates are helpful when evaluating fluvial health, because they are often the first g...
