We prove a general lemma on the existence of {I/r)-cuttings of geometric objects in Ed that satisfy certain properties. We use this lemma to construct (I/r)-cuttings of (asymptotically) optimal size for arrangements of line segments in the plane and arrangements oftriangles in 3-space; for line segments in the plane we obtain a cutting of size O(r + Ar2/n2 ), and for triangles in 3-space our cu...

The work aimed to study all the possible factors affecting efficiency of plant propagation via stem cuttings. Several factors including type of cutting, culture medium, type and concentration of growth regulators were investigated. These factors were studied on Ficus hawaii as woody tree and Chrysanthemum morifolium as herbaceous plant to investigate the effect of plant type factor. All experim...

Cost-efficient tracers with fast and simple detection quantification methods at low limits via on-site is a current industrial target for state-of-the-art tracer tests. To bridge the gap between desired properties limits, we developed broad spectrum of robust cost-efficient fluorescent tags to innovate reservoir management practices. We engineered new extended test applications real-time well-d...

T h e nor thern root-knot nematode, Meloidogyne hapla Chitwood, 1949, parasitizes a number of impor tant crops in Washington (1). M. hapla is widespread on Concord grapes (Vitis labrusca L.), and heavy infestations have been associated with vines with poor growth. All the same, a greenhouse pathogenicity study with an isolate of M. hapla from alfalfa (Medicago sativum L.) showed that Concord gr...

This study aims to determine the effect of composition growing media and natural growth regulators their interactions on lemon cuttings. research was conducted at Banjar Dinas Pangereregan Kaja, Lumbung Village, Selemadeg Barat District, Tabanan Regency. The altitude site is 200 m above sea level. from 23 January 2022 20 March for 8 weeks planting interaction between treatment medium regulator ...
