The critical arguments for radiofrequency radiation exposure limits are currently based on the principle that radio frequencies (RF) and electromagnetic fields (EMFs) are non-ionising, and their exposure limits are even 100-fold lower than those emitted ...

The Current Status and the Long-Term Variations of Water Quality in Lake Manzala, Egypt [PDF]
This study aimed to shed light on the long-term current state and variations of Lake Manzala water quality by some chemical, physical, and biological properties as: temperature, pH, total solids, hardness, sodium, chlorides, total nitrogen, total ...

Exploring the Limits of Biological Complexity Amenable to Studies by Incoherent Neutron Spectroscopy
The wavelengths of neutrons available at neutron scattering facilities are comparable with intra- and inter-molecular distances, while their energies are comparable with molecular vibrational energies, making such neutrons highly suitable for studies of ...

Informational limits of biological organisms [PDF]
Genomic analyses have revealed that free‐living biological organisms carry between 10 7 and 10 11 bits of information in their genomes. In large organisms with relatively small population sizes, such as humans, only in the order of 1% of the genomic information is shaped by the environment via natural selection.

In live-cell microscopy, motion blur limits resolution and contrast. Here the authors use 100 Hz super-resolving Rotating Coherent Scattering (ROCS) microscopy on various dynamic biological systems, and time-window analysis to understand biological ...

Optical Biosensors and Their Applications for the Detection of Water Pollutants
The correct detection and quantification of pollutants in water is key to regulating their presence in the environment. Biosensors offer several advantages, such as minimal sample preparation, short measurement times, high specificity and sensibility and

Grazing limits natural biological controls of woody encroachment in Inner Mongolia Steppe
Woody encroachment in grasslands has become increasingly problematic globally. Grazing by domestic animals can facilitate woody encroachment by reducing competition from herbaceous plants and fire frequency.

Revisiting safe biological limits in fisheries
AbstractThe appropriateness of three official fisheries management reference points used in the north‐east Atlantic was investigated: (i) the smallest stock size that is still within safe biological limits (SSBpa), (ii) the maximum sustainable rate of exploitation (Fmsy) and (iii) the age at first capture. As for (i), in 45% of the examined stocks, the

Challenges and Limitations of Biological Network Analysis
High-Throughput technologies are producing an increasing volume of data that needs large amounts of data storage, effective data models and efficient, possibly parallel analysis algorithms. Pathway and interactomics data are represented as graphs and add a new dimension of analysis, allowing, among other features, graph-based comparison of organisms ...
