In order to investigate the effect of seed priming on yield, yield components and some quality characteristics of rainfed wheat Azar2 cultivar, an experiment was conducted as a randomized complete blocks design with three replications in the Research Field of Kurdistan University, Sannandaj, Iran during two seasons (2018-2020). Priming treatments included control (nonprime), potassium chloride ...
“Is there a mouthwash or toothpaste that removes this plaque and calculus?” asks the patient undergoing periodontal treatment, particularly one who has not succeeded in removing plaque with a toothbrush and dental floss. In reviewing the literature on this subject it was found that scientists and clinical researchers are making a determined effort to understand plaque, while at the same time te...
We investigated the effects of Heterodera glycines cyst components and surface disinfestants on hatching of H. glycines eggs in vitro. Eggs were incubated in either H. glycines cyst wall fragments, cyst wall and egg rinsate, egg homogenate, or control solutions of soybean root diffusate, sterile distilled water, or zinc sulfate. Hatch in cyst wall and egg rinsate, and egg homogenate, was greate...
Fourteen cations were tested at a 1% concentration (wt:wt), as chlorides, for their effects on the biological activity of the gypsy moth, Lymantria dispar (L.), nuclear polyhedrosis virus (LdMNPV). Cupric chloride was toxic to gypsy moth larvae. Ferrous and ferric chloride were inhibitory to larval growth and development as well as to virus activity. Strontium chloride was inhibitory to virus a...
A large number of reinforced concrete structures subjected to chloride ions. Two basicapproaches for preventing corrosion of reinforcing steel embedded in concrete are: Increasing theconsolidation of concrete and using different coating on rebars. In present research steel rebarsare coated in different ways: a) 40 µm of zinc electroplated on steel rebar b) Zinc powder withepoxy paste (zinc rich...
A wide range of volcanic sublimates and alteration products from the Johnston-Lavis collection z has been analysed for major elements plus copper, lead, and zinc. 'Aphthitalite' and 'natrikalite' from Mount Vesuvius and an 'alum' from the island of Vulcano all proved to be enriched in copper and selected analyses are tabulated. The process leading to copper and lead enrichment of the Vesuvian m...
Background: Postpartum depression is a mood disorder that has harmful effects on mothers, infants, family and relationships. Acute decrease of progesterone after delivery has been proposed as a cause for postpartum depression. This hormone can affect neurotransmitters' function. Zinc (Zn) and magnesium (Mg) as trace elements exert their antidepressant effects through neurotransmitter pathway...
