Objective: In this study investigated effects of different amounts of pelleted manure with urea and micro elements on yield and seed quality of medicinal plants, pumpkin (Cucurbita pepo var. styriaca). Methods: The animal manure and urea as pellet with four levels (150 Kg urea, 50 Kg urea + 3.5 ton animal manure, 100 (Kg) urea+ 1.5 ton animal manure and 150 (Kg) urea+1.5 ton animal man...

We introduce a novel amortization technique for computation of consecutive preimages of hash chains, given knowledge of the seed. While all previously known techniques have a memorytimes-computational complexity of O(n) per chain element, the complexity of our technique can be upper bounded at O(log n), making it a useful primitive for low-cost applications such as authentication, signatures an...

BACKGROUND AND AIMS Myrmecochory is a conspicuous feature of several sclerophyll ecosystems around the world but it has received little attention in the semi-arid areas of South America. This study addresses the importance of seed dispersal by ants in a 2500-km(2) area of the Caatinga ecosystem (north-east Brazil) and investigates ant-derived benefits to the plant through myrmecochory. METHOD...

Influences on viability and germination of seeds have been studied intensively for many years, particularly for the numer-ous commercially important agricultural, ornamental, and timber species. High germinating seed lots may differ substantially in field emergence when sown at the same time in the same field, and/or may differ in performance after storage in the same environment or transport t...

Background and aims. Promoting remineralization is the ultimate goal of clinical prevention of caries lesion. The present in vitro study aimed to investigate the effect of grape seed extract (GSE) on artificial enamel caries in primary human teeth. Materials and methods. Seventeen human sound primary incisors were sectioned mesiodistally. The tooth slices were placed in a demineralizing solutio...

There is increasing interest among growers in novel establishment systems for cover crops that can rehabilitate and protect soil. Cropping intensification has led to yield declines, compacted and poor quality soil, and increased pest problems. Cover crops in the Brassica (mustard) family offer benefits in soil conservation, improvement in soil quality, reduction in nitrate leaching, and suppres...

Background: The global incidence of snakebite has become a major concern to the community. This study aimed to evaluate the effect of mango seed kernel methanol extract on metalloproteases in Carpet Viper (Echis ocellatus) venom. Methods: Mango seed kernel methanolic extract was evaluated in vitro for its anti-venom activity and inhibition of metalloproteases of Carpet Viper's (Echis ocellatus...

The aims of this study were to investigate the effects of hesperidin, a citrus flavonoid, on human root dentin demineralization and collagen preservation, and compare it with chlorhexidine and grape seed extract. Specimens were assigned to different treatment groups: hesperidin, chlorhexidine and grape seed extract. Specimens were subjected to pH cycling by demineralization for 14 h, incubation...
