The paper "Development a prototype of mobile laminar air flow instrument" presents research on the view toward the realization of a mobile laminar airflow system for preventing the contamination of airborne pathogens by protecting the surgical site area as well as the instrument table at low-cost. Simulations with computational fluid dynamics (CFD) were conducted to optimizing system design. The simulation results were examined and evaluated in this paper.

In the study "Swash model approach for flows induced by low-frequency waves over wooden fences" the low-frequency wave, which is considered the main contribution to flows, is focused on assessing the possibility of sediment transports through the wooden fence. This study applies the SWASH model developed by Delft University of Technology to carry out a couple of wave scenarios for the southeast and northeast monsoons that were inherited from a previous study.

The experimental results show that the flow of all CLSM mixtures met high flowability requirements under ACI 229R. Using BA as fine aggregate reduced the fresh unit weight of CLSM but delayed the setting time. Moreover, CLSM mixtures could serve as a re-excavation and pavement subbase.

Porous sunshade roof cover sheets installed on building roofs are new structures for mitigating heat absorption. Thus, there have been few studies on wind flow and its effects on windpermeable structures, and there is no provision for these structures in the major international wind load standards and codes.

Saline intrusion is one of the most frequently occurring natural disasters in a coastal area, posing the most serious impact in the Vietnamese Mekong Delta (MD). With the characteristics of the region as an open and low system, located at the end of the Mekong River basin and part of the Vam Co River system, this region is strongly affected by the tidal regime, and therefore saline intrusion is a feature of the region and has become familiar to the people living here in the dry season.

Despite an increase in governments' demand for private participation in infrastructure, Public-Private Partnerships (PPPs) have received low engagement from the private sector in the task of bridging infrastructure gaps in emerging markets. Previous literature in the field mainly focuses on the effects of PPPs from the governments' perspective and it is inconclusive in its examination of the advantages and disadvantages of the private sector's participation.

Marine fish populations are often characterized by high levels of gene flow and correspondingly low genetic divergence. This presents a challenge to define management units. Goldsinny wrasse (Ctenolabrus rupestris) is a heavily exploited species due to its importance as a cleaner-fish in commercial salmonid aquaculture. However, at the present, the population genetic structure of this species is still largely unresolved.

In the present work a galactomannan extract of low protein residue (< 1.3 % wt dry basis) was isolated from alfalfa (Medicago sativa L.) seed endosperm meal. The alfalfa gum (AAG) comprised primarily mannose and galactose at a ratio of 1.18:1, had a molecular weight of 2 × 106 Da and a radius of gyration of 48.7 nm.

The performance of an original CE-MS interface that allows the in-axis positioning of the electrospray with respect to the MS inlet was evaluated. The variations in the geometrical alignment of this configuration in the absence of a nebulizing gas afforded a significant reduction in the sheath-liquid flow rate from 3 μL/min to as low as 300 nL/min.

Over 170 post-transcriptional RNA modifications have been described and are common in all kingdoms of life. These modifications range from methylation to complex chemical structures, with methylation being the most abundant. RNA modifications play a key role in RNA folding and function and their dysregulation in humans has been linked to several diseases such as cancer, metabolic diseases or neurological disorder

The pilot test of GAGD was recorded with a good oil rate and low water-cut during flowing back after gas injection and shut-in for gas segregation, which suggests the positive effectiveness of GAGD to some degree. The expansion of the GAGD application to other wells and areas in the field would be encouraged in any similar situation.

Magnetite (Fe3O4) is a potential material for spintronic development due to its high Curie temperature (858 K) and half-metallic structure with only one spin polarization at Fermi level. The bulk properties of Fe3O4 make it a big challenge to grow perfectly stoichiometric thin films at a low temperature.

The low-lying terrain in downstream area of Sai Gon - Dong Nai river is mostly affected by natural disasters such as flooding, saltwater intrusion causing difficulties in process of socio-economic development. The project of building Vung Tau - Go Cong sea dyke with a length of 32 km was proposed to solve these problems, particularly creating a reservoir for storing water and preventing saltwater intrusion, expanding urban space, industrial parks, tourism, services, shelter for boats from the storm, reserving fresh water in the future.

This paper reports the optimization of the molybdenum thin film electrode as the back contact of dye-sensitized solar cell (DSSC). The molybdenum thin film was grown on the glass substrate by direct current sputtering techniques of which the sputtering power was 150 W at 18 sccm flow rate of Ar. At such sputtering parameters, the Mo film can reach the lowest resistivity of 1.28E−6 cm at 400 nm thick. And the reflection of Mo membrane was 82%. This value is considered as a very good result for preparation of the back contact of DSSC.

Microcirculatory driving pressure is defined as the difference between post-arteriolar and venular pressure. In previous research, an absence of correlation between mean arterial blood pressure (MAP) and microcirculatory perfusion has been observed. However, the microcirculation may be considered as a low pressure compartment with capillary pressure closer to venous than to arterial pressure.
