Activated carbon filters play an important role in water filtration and purification from contaminants of different origin. Their limit consists in bacterial proliferation, which may occur only during prolonged periods of non-use and in their ability to remove radioactive contaminants present in waste water from Industry or Nuclear Medicine departments. In this work we tested a commercially ava...

Biological systems have, through the course of time, evolved unique solutions for complex optical problems. These solutions are often achieved through a sophisticated control of fine structural features. Here we present a detailed study of the optical properties of basalia spicules from the glass sponge Euplectella aspergillum and reconcile them with structural characteristics. We show these bi...

Many load bearing biological structures (LBBSs)-such as feather rachises and spicules-are small (<1 mm) but not microscopic. Measuring the flexural behavior of these LBBSs is important for understanding the origins of their remarkable mechanical functions. We describe a protocol for performing three-point bending tests using a custom-built mechanical testing device that can measure forces rangi...

A comparative study of the microscopic morphology and chemical characteristics spicules Hexactinellids (Hexactinellida) with different structural features skeletons, as well freshwater Baikal sponge belonging to class common sponges (Demospongia), was carried out. The trace element composition determined by X-ray fluorescence spectrometry. siliceous contain many elements, arranged in decreasing...

The aim of this research is to develop a safe and effective anthelmintic from plants, due the resistance toxic effect synthetic anthelmintics on animals humans. There are several side effects for drugs including drug resistance, toxicity, residual in animal products. So there need exploration medicinal plants treatment different types worm infections.&#x0D; In medicinally traditionally importan...

In the Philippines, use of non-native earthworm species in vermicomposting is popular. Given that country a vital geographical resource for diversity, study to establish potential their vermicasts agricultural applications essential. this study, bacteria associated with recently described indigenous species, Pheretima losbanosensis, were investigated using next-generation sequencing, community-...
