Healing and acclimatization are critical in vegetable grafting under controlled environments. Here, we investigated the impacts of LED light qualities on morphological traits photosynthetic performance grafted tomato seedlings. Seeds tomatoes “DRW 7806 F1” “Maxifort” (Solanum lycopersicum × Solanum habrochaites) used as scion rootstock were planted 104-cell plug trays into a mixture cocopeat pe...

This study evaluated the bioactivity of polypropylene melt-blown filtering nonwovens used in respiratory protective devices (RPD) with a biocidal agent (alkylammonium microbiocides) on 2 mineral carriers. Two types of carriers were tested: a bentonite, with an aluminosilicate base, and a perlite, volcanic glass. High biostatic and biocidal effects of modified nonwovens with biocides were tested...

In order to evaluate the different growing media and nitrogen fertilizer (urea) on some morphological traits of Spathiphyllum plant, an experiment was carried out in split plot arrangement based on completely randomized design in three replications in greenhouse conditions in 2018. The main plot consisted of different growing media including T1: Leaf-mold, T2: Vermicompost and T3: A mi...

Expanded perlite has been assumed as simple nuisance, however during an accidental spill out in Taiwan, among 24 exposed workers followed for more than 6 months, three developed persisted respiratory symptoms and positive provocation tests were compatible with reactive airway dysfunction syndrome. During simulation experiment expanded perlite is shown to be very dusty and greatly exceed current...

Abstract Soil degradation is a serious problem in Indonesia and the world. To solve such it can use coco peat derived from coconut fiber, which source very abundant Indonesia. The research aimed to understand impact of bio-textile application prevent run-off erosion indicated by cover crop growing. material used was cocopeat pressed block at dimension 30 cm x 2.5 thickness. It completed seed co...

Before acclimatization of Bowiea volubilis, in vitro propagated bulbs were cleaned and separated into four sizes (from 6 to 15 mm). We formed a total 10 groups with 30-30 individuals, distributing the evenly. Four types substrate (peat, perlite, coconut fiber, sand) their mixtures 50-50% used. Previously we examined three parameters: length, diameter weight bulbs; later successfully acclimatize...

Mineral phases and their content were determined in attic dust samples collected from 27 houses in the Tikveš Valley, Republic of Macedonia. By using quantitative X-ray diffraction, the principal mineral phases were determined to be the serpentinite group (chrysotile, lizardite) and amphibole group of minerals (ribecite, tremolite, actinolite) present in the attic dust samples from this region ...

This paper puts forward a scheme to form perlite sound absorption boards by vibration molding according to the material properties and the characteristics of vibration forming method. In the trial, the feasibility and reliability of this method were confirmed by studying the effect of working pressure, frequency and vibration force on the quality of the perlite sound absorption board. Besides, ...

Abstract Zamiifolia (Zamioculcas zamiifolia) is an ornamental and perennial medicinal plant, which belongs to Araceae family. This plant holds a prominent place in the economic significance of this particular study aimed examine process root development rhizome production through leaf cuttings zamiifoliain experiment. experiment was conducted as factorial design within completely randomized fra...
