Anastomosing fluvial systems have multiple shallow channels that branch and rejoin with a sinuosity over 2.0. They are dominated by mud deposits and characteristic of large perennial rivers with very low gradients. Channel deposits show thin beds of cross-bedded sandstone within thick overbank successions of laminated mud and peat. Unlike meandering rivers, anastomosing rivers have channels that become vertically stacked due to high subsidence rates rather than migrating laterally.
Sedimentary basins are the depressions in the earth's crust where loose particles accumulate and finally lithified to form sedimentary rocks. Basins are particularly attractive to geoscientists from time immemorial due to the wealth hidden here in the form of oil, gas, coal etc. In this document you will find the types of basins, basin-fill types, methods of basin analysis and so on.

Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

1. Anastomosing Fluvial System
(Multichannel/mud-dominated)
Anastomosing fluvial systems have multiple, relatively shallow channels
with a sinuosity of at least 2.0, a very low bed/suspended load ratio, and
highly cohesive bank material. Anastomosing river deposits are
typically dominated by mud and are characteristic of high-discharge
perennial rivers flowing over very low gradients.
2. • Low gradient relative to discharge
• High discharge relative to load
• Very low bed load relative to suspended load
• Very cohesive bank materials (commonly muddy & vegetated)
• Perennial discharge with relatively low fluctuation
Conditions Favoring Anastomosing
3. Simplified Model
Anastomosed fluvial systems have facies associations similar to those
of meandering systems (active channel, abandoned channel, overbank,
splay) but in different proportions and with different geometries.
4. Contrast with Meandering
Channel processes are similar for both meandering and anastomosed
stystems. The main difference is that subsidence rates are so high for
anastomosed systems that channels become vertically stacked, rather
than migrate laterally.
5. Common Facies
Anastomosed rivers are dominated by
muddy facies representing thick
floodplain successions. Swamp, peat
bogg, splay, and other environments are
common. Channel facies show point bar
successions that are not as well developed
as those of meandering systems.
6. Channel belt
Splay
Floodplain
Common Facies
Narrow, but thick deposits of trough cross-bedded
sandstone dominate channel deposits. Thick overbank
successions composed of laminated mud are common
and often include significant deposits of peat. Thin
beds of trough cross-bedded to ripple-bedded sandstone
interbedded with mudstone represent splay deposits.
7. Large-scale Architecture
Anastomosed fluvial systems are characterized by:
• Low sand:mud ratio
• Low sand body connectivity
• Lens geometry
• Very high accommodation development
