Information on the tiller development of hybrid bromegrass (Bromus inermis × Bromus riparius Rehm) is limited. The objective this study was to evaluate effect clipping frequency at vegetative and reproductive stages concentrations sugars ‘AC Knowles’ compared ‘Kirk’ crested wheatgrass (Agropyron cristatum L.). This experiment conducted in greenhouse using tillers vernalized plants dug from fiel...

In this paper, we introduce a reduced order model (ROM) for the propagation of nonlinear multi-directional ocean wave-fields. The ROM relies on Galerkin projection Zakharov equations embedded in high-order spectral (HOS) method, which describes evolution waves. dominant flow features wave are computed from proper orthogonal decomposition (POD) and these modes used projection. HOS scheme to comp...

Low-crested and submerged breakwaters are frequently employed as coastal defence structures. Their efficiency is governed by wave energy dissipation, the transmission coefficient can evaluate this parameter. The current study conducts experimental investigations on both low-crested exposed to different conditions compare their performance with that of emerged breakwaters. provides a comprehensi...

The sluicing flume that was designed is less capable of silting up and losing its calibration than its counterparts of standard sharp-crested compound weir design. The laboratory work described here led to a refinement in the design in the form of a short flume set into the lowest section of a compound Crump weir gauging installation. Critical flow occurs near the exit of this flume, and it is ...

This paper presents the first census of captive gibbons in selected zoos and other institutions of China and Vietnam. All institutions which were suspected to keep gibbons of the Hylobates concolor group were visited by the author in 1990 and/or 1993. In Chinese institutions, H. hoolock was relatively common, whereas in Vietnam, H. gabriellae was the species most frequently seen in captivity. S...

A new species, Lysimachia huangsangensis (Primulaceae), from Hunan, China is described and illustrated. The new species is closely related to L. carinata because of the crested calyx, but differs in the leaf blades that are ovate to elliptic and (3-)4.5-9 × 2-3.4 cm, 2-5-flowered racemes, and the calyx lobes that are ovate-lanceolate and 5-6 × 3-4 mm. The systematic placement and conservation s...

For generating electricity, direct-drive wave energy converters (WECs) with linear permanent magnet generators (LPMGs) have advantages in terms of efficiency, simplicity, and force-to-weight ratio over WEC rotary generators. However, the converter’s work under approaching-real conditions should be investigated. This paper studies performance a pico-scale two different LPMGs unidirectional long-...
