1. Behavior of plaster with water-repellent additive under natural aging
Abstract This research evaluates the behavior of plaster with a water-repellent additive when submitted to a natural aging process. Casting plaster and silane/siloxane-based water-repellent were used as materials. The water/plaster ratio was set at 0.7 and the contents of 0.2% and 0.4% of water-repellent were used, in relation to the plaster mass. Plaster pa

2. Pathogenicity of Metarhizium anisopliae and Beauveria bassiana fungi to Tetranychus ludeni (Acari: Tetranychidae)
RESUMO O uso de acaricidas é o principal método de controle de Tetranychus ludeni (Acari: Tetranychidae) em cultivos hortícolas. Esse ácaro foi registrado causando danos em batata-doce (Ipomoea batatas (L.). A utilização de fungos patogênicos é uma alternativa ao controle químico. O objetivo foi avaliar a patogenicidade dos fungos Metarhizium anisop

3. Surface morphology and repellency mechanism investigation of Salvinia molesta plant
ABSTRACT Bionics is a versatile tool with a technological potential, which designers use to search for signs and clues about functional elements and mechanisms in nature that allow for the development of products. The purpose of this study was to analyze the morphology of the aquatic plant Salvinia molesta, aiming to determine the water repellency of its lea

4. Larvicidal activity of Syzygium aromaticum (L.) Merr and Citrus sinensis (L.) Osbeck essential oils and their antagonistic effects with temephos in resistant populations of Aedes aegypti
Environmentally friendly botanical larvicides are commonly considered as an alternative to synthetic larvicides against Aedes aegypti Linn. In addition, mosquito resistance to currently used larvicides has motivated research to find new compounds acting via different mechanisms of action, with the goal of controlling the spread of mosquitos. Essential oils h

5. Hidrofobicidade em Neossolo litólico sob plantação de Pinus taeda.
Compreender os processos de estabilização do carbono no solo pode ser muito útil no desenvolvimento de técnicas de mitigação das emissões de CO2 e do aquecimento global. Quanto maior a hidrofobicidade da matéria orgânica do solo, mais estabilizado é o carbono do solo. Portanto, a hidrofobicidade pode ser usada como indicador para caracterizar a qua

6. Seletividade de fungos entomopatogênicos a Trichogramma pretiosum Riley (Hymenoptera: trichogrammatidae) e virulência a Bemisia tabaci (Hemiptera: Aleyrodidae
The entomopathogenic fungi and the parasitoid Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) can be used, at the same time, in the tomato culture. However, it is still unclear the effects of entomopathogenic fungi on T. pretiosum. Thus, this study aimed to analyze the selectivity of entomopathogenic fungi against T. pretiosum and assess the vi

7. Water repellency induced by pulmonary surfactants.
1. Pure cotton fabric was partially carboxylated to produce a tough, porous, hydrophilic sub-phase to stimulate the epithelial membrane of the alveolar wall from a permeability standpoint. 2. Two of the predominant pulmonary surfactants, dipalmitoyl lecithin (DPL) and dipalmitoyl phosphatidylethanolamine (DPPE), were found to inhibit wetting of this syntheti

8. Pulmonary surfactant: hydrophobic nature of the mucosal surface of the human amnion.
The contact angle has been measured for a drop of saline placed upon the rinsed mucosal surface of the amnion in eleven human placental membranes obtained from normal births at full term. The contact angle averaged 70 degrees, indicating a hydrophobic surface comparable with graphite (86 degrees), polyethylene (94 degrees) or oxyntic tissue (85 degrees) whic
