Bromeliaceae arose in the Early Cretaceous, diverging from Typhaceae at ca. 125 Ma. After an apparent evolutionary stasis of 100 million years, they have undergone a high diversification starting Miocene. By adding fossils to phylogenies, one can infer dates arising and divergence lineages link them geological climatic events. The use reliable fossils, therefore, greatly impact results interpre...

In this study, we propose dynamic prioritization of image macro-blocks for Wireless Multimedia Sensor Networks (WMSN). An encoding scheme is employed at the source node by labeling the blocks as “important” or “not-important” based on the information they contain. We introduce a set of novel priority measures to weigh importance of macro-blocks using their intrinsic properties. Experimental res...

in order to the effects of macronutrients  and micronutrients on morphological traits and yields of rice, an examination as factorial in random complete block design and 3 replicate in galoogah region during the year of 2014 conducted. the treatments of nutrients were microelements, microelements, and the mixture of microelements, macro elements and control. the results showed the treatments ha...

rue, ruta graveolens, is a medicinal plant in traditional medicine that has several therapeutic properties such as anti-carcinogenic agent, antioxidant, anti-inflammatory, antimicrobial, hypotensive, and spasmolytic. this study was carried out to evaluate the antibacterial effects of the etanolic extract of rue against piscine pathogenic bacteria viz. lactococcus garvieae and aeromonas hydrophi...

Three-dimensional analyses of the early Ediacaran microfossils from the Weng'an biota (Doushantuo Formation) have focused predominantly on multicellular forms that have been interpreted as embryos, and yet they have defied phylogenetic interpretation principally because of absence of evidence from other stages in their life cycle. It is therefore unfortunate that the affinities of the various o...

Biomineralization marks one of the most significant evolutionary milestones among the Eukarya, but its roots in the fossil record remain obscure. We report crystallographic and geochemical evidence for controlled eukaryotic biomineralization in Neoproterozoic scale microfossils from the Fifteenmile Group of Yukon, Canada. High-resolution transmission electron microscopy reveals that the microfo...

Cocoa beans (Theobroma cacao) are processed into cocoa beverage through fermentation, drying, roasting and grounding of the seed to powder. The mycological quality of 39 samples of different brand of these cocoa – based beverage referred to as ‘eruku oshodi’ collected from 3 different markets in south – west Nigeria was determined by serial dilution using the pour plate method on Potato Dextros...

paddy straw is one of the most abundant agricultural by-products in tamil nadu, india. itcontains high amounts of cellulose and lignin. the fungal strains were isolated from naturally decomposingsites of paddy straw. eight fungal strains were isolated and later these eight fungi were used for finding outtheir potential for the degradation of lignin and cellulose content of paddy straw. among ei...
