Coupled dual-beam focused ion beam electron microscopy (FIB-EM) has gained popularity across multiple disciplines over the past decade. Widely utilized as a stand-alone instrument for micromachining and metal or insulator deposition in numerous industries, the submicron-scale ion milling and cutting capabilities of FIB-EM systems have been well documented in the materials science literature. Th...

abstract valerian medicinal plant (valeriana officinalis) is a perennial succulent plant that is natural lenitive and good ingrained of diazepam. this study was conducted in order to identify the fungal agents of rhizome and root rot of valerian. infected plant samples that showed the symptoms of rotting and necrosis were collected from karaj and used in order to isolate disease agents. symptom...

Studies on physical induced mutagenesis, gamma rays were performed by exposing the healthy and dry seeds of cowpea variety CO 4 to gamma rays 20, 30, 40, 50, 60 and 70 kR. The study was to evolve economically important mutants with varied seed coat colour as against dark grey coloured seed coat of CO 4. The LD50 value was found at 50kR for 60 Co gamma rays. Under field conditions, germination, ...

Aqueous and ethanolic extracts obtained from nine Chilean marine macro-algae collected at different seasons were examined in vitro and in vivo for properties that reduce the growth of plant pathogens or decrease the injury severity of plant foliar tissues following pathogen infection. Particular crude aqueous or organic extracts showed effects on the growth of pathogenic bacteria whereas others...

Elevated enzyme activities in plasma may at times be attributed to the presence of macro-enzymes. The macro-enzymes are often serum enzymes in complex with immunoglobulins, resulting in a greater molecular mass that cannot be filtered by renal glomeruli and are, hence, retained in the plasma. The aspartate aminotransferase (AST) can exist as a macro-enzyme, although it has been rarely reported....

abstract soil invertebrate and their spatial pattern are affected strongly by environmental factors. spatial variability of soil properties is one of the most important reasons of the macrofauna variability. this study was conducted to investigate the spatial variability of soil properties and soil macrofauna biomass in the riparian forest landscape of karkhe river. soil macro fauna were sample...

In East Timor’s diversified subsistence economy, rice and maize are today common staples in some areas but root crops and arboriculture, too, play an important role. Although a cultural and chronometric framework for the introduction of agriculture in East Timor has long been proposed, little is known about the exact history of early plant use in the island. This paper deals with preliminary fi...
