Jiaogulan (Gynostemma pentaphyllum (Thunb.) Makino) is distributed mostly in mountainous areas, in shaded and humid places at 300-3200 meters above sea level. This study was conducted to determine the appropriate application dose of nitrogen for the growth of Jiaogulan under different shading conditions.

The prognostic significance of mast cells and different phenotypes of macrophages in the microenvironment of hepatocellular carcinoma (HCC) following resection is unclear. We aimed in this study to assess the local distribution of infiltrating macrophages and mast cells of specific phenotypes in tissues of HCC and to evaluate their prognostic values for survival of post-surgical patients.

This paper investigates the nonlinear vibration of saturated porous functionally graded plate subjected to the combination of mechanical and thermal loadings. Three different distributions of porosity are considered. Based on the Biot and higher order shear deformation theories, the vibration characteristics including natural frequency, deflection amplitude – time curves and relation between frequency ratio and amplitude of the saturated porous plate are determined.

Ebook "Estimating in heavy construction: Roads, bridges, tunnels, foundations" provides a good basis for estimation because all important cost categories are considered. The risks of different construction contracts are systematically evaluated with regard to risk distribution between owner and contractor. Specific risks, for instance for joint ventures, are also considered. A systematic scheme for the calculation of interim interest is provided as well.

This work focuses on the free vibration of the functionally graded porous (FGP) sandwich microplates using the isogeometric approach (IGA). The FGP sandwich plate comprises the homogeneous core and the FG porous face sheets. The material properties of the FGP face sheets are supposed to vary through the thickness direction according to the power-law function and modified rule of a mixture of the volume fraction with three different types of porosity distribution: homogeneous porous, X porous and V porous distributions.

Large deflections of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) sandwich beams are studied in this paper by a nonlinear finite element procedure. The core of the beams is homogeneous while the two faces are of CNTRC material. The effective properties of the two CNTRC face sheets are determined by an extended rule of mixture. CNTs are reinforced into matrix phase through uniform distribution (UD) or four different types of functionally graded (FG) distribution, named as FG-X, FG-A, FG-V, FG-O.

A study on Mollusks’ species composition and distribution on dead coral from Quang Ngai to Cat Ba was conducted during the field survey between Vietnam and Russia on the AKADEMIC OPARIN RC vessel in 2021 at 39 reef stations in 14 study areas. By comparative morphology method, the authors have identified 135 taxa of Mollusca belonging to 48 families, 4 classes on coral reefs. The species composition of Mollusca was slightly different between study areas.

The taxonomic treatment with a description is provided, along with photographs, distribution, ecology, a conservation assessment, and morphological comparison with its alliance species. It is similar to Zingiber orbiculatum and Zingiber mioga in having whitish flowers and bright yellow anthers but differs in many aspects of vegetative and reproductive characteristics. Moreover, a taxonomic key for all species of sect. Cryptanthium in Vietnam is included.

This study is conducted based on the hypothesis of an accident from Fengcheng NPP with an incident level of 7, equivalent to the Fukushima accident. A modeling system has been established with different failure scenarios based on the Delft3D model. The research results will provide more insights into the extent and scope of the incident and the impact of meteorological conditions and dynamics on the propagation and distribution of radiation when an incident occurs.

The study found that nematode composition differed significantly between the upper and deeper layers of sediment but not among the deeper layers. Nematode density showed spatial variability across layers, with higher values in the upper layer. Nematode diversity decreased with increasing depth. Non–selective deposit feeders (1B) were dominated in the surface layers, while the predator–omnivores feeders (2B) was numerous in the deeper layers

Preserving the integrity of halal food has become increasingly complex since its supply chain undergoes numerous production processes and distribution stages performed by different organisations. The longer the supply chain is, the greater its vulnerability and complexity. Concurrently, the rise in the number of halal food product status revocation indicates their non-compliance with Shariah requirements.

Picking and packing is the one of the main principle action in a distribution centre. Picking and packing action ensures the right product at the right quantity reaches the right customer. As such, this study is purported to recognize the issues related to picking and packing error and to know how to overcome it. The study was conducted using a semi-structured interview to elicit response concerning picking and packing issues and error.
