This research was conducted to investigate the effects of natural zeolite on vegetative growth, flower and physiological characteristics of African marigold (Tagetes erecta L. 'Queen'). The experiment was performed as a completely randomized design with six treatments (2, 4, 6, 8 and 10 g zeolite/kg soil mixture along with control) and 5 replications. Results indicated that zeolite decreased leaching of nitrogen, potassium, phosphorus, calcium, and magnesium due to increase in cation exchange capacity (CEC) of soil mixture. Application of zeolite in the medium resulted in significant increase in photosynthetic rate, mesophyll efficiency, water use efficiency, chlorophyll content, fresh and dry weights of roots and shoots, leaf area and flower length, but did not significantly affect flower diameter and stomatal conductance. It was concluded that zeolite had a pronounced effect on vegetative growth, flower and physiological characteristics of African marigold. It my be recommended that zeolite being used, as an amendment to soil of ornamental plants such as African marigold to decrease nutrient leaching and irrigation interval.

The present study evaluated the efficacy of Maxforce gel baits containing 0.01% fipronil (Maxforce), 0.05% fipronil (Maxforce Magnum), 1.0% clothianidin (Maxforce Impact), and 0.6% indoxacarb (Avion gel bait; all from Bayer Environmental Science, Clayton, CA, USA) against reference and wild strains (Mobasher, Andisheh, Tamin‐e Ejtemaei, and Maskoni) of German cockroach collected in 2016. Test design and bait placement were according to World Health Organization (WHO) procedures for efficacy achieving a 95% mortality rate. Although cockroaches fed on all gel baits, gel baits containing clothianidin and indoxacarb were eaten at higher rates than gel baits containing 0.01% and 0.05% fipronil. The cumulative mortality rates reached 100% for all cockroach strains at 32, 28, 28 and 40 h after eating baits containing 0.01% fipronil, 0.05% fipronil, clothianidin, and indoxacarb, respectively. Efficacy (a 95% mortality rate) after exposure (consumption) of gel baits containing 0.05% fipronil and clothianidin was seen after 28 h, compared with 32 h for 0.01% fipronil and 40 h for indoxacarb. In conclusion, commercial gel baits have improved and may be more effective than spray formulations against German cockroaches.

Polycaprolactone (PCL) based nanocomposite scaffolds containing graphene (Gr) and baghdadite (BAG)nanoparticles were fabricated using the electrospinning method. Mechanical properties of the scaffolds were evaluated. Viability and adhesion of cells on the scaffolds were confirmed using fluorescence optical microscopy, MTT and FE-SEManalysis methods. The results indicated that incorporation of various concentrations of BAG from 1 to 3 wt% notablyimproved the mechanical properties. Cell adhesion assay revealed that the addition of BAG nanoparticles to PCL-Gr scaffoldcaused further adhesion, viability, and proliferation of the cells.
